Description

Improvement of luggage structure with fresh-keeping function

The present invention relates to a suitcase, and in particular to an improved structure of a suitcase with a fresh-keeping function.

According to the recent progress of technology, transportation is no longer an obstacle to people's mobility, and domestic and foreign travel has become a leisure way for people to relieve work pressure or expand their horizons. Usually, if a long travel itinerary requires a lot of preparations, such as spare clothes, sanitary products, electronic products, etc., then a storage tool that is easy to carry and move is needed. Among them, suitcases are the most commonly used storage items. Common suitcases include a box body with a storage space inside that can store various items of the user; and a pull rod connected to the box body for the user to hold to tilt the box body and drag the suitcase to move.

Among them, since the storage space of the suitcase is often designed to be difficult to open (such as a lock or buckle), although it can prevent the items inside from being easily taken away, sometimes users will feel troubled when they want to take out the items. Therefore, the industry has developed a suitcase with multiple storage spaces. In addition to the main storage space, a smaller storage space is provided on one side close to the handle for users to place some items that need to be taken out, such as food bought at the airport, snacks, fresh food, etc.

However, the problem with placing food in a suitcase is that some food or fresh food will spoil or rot if it is out of the refrigerated space for too long, and the suitcase does not have a fresh-keeping function, so it will cause the user to be unable to use the suitcase to carry those foods or fresh food, which is very inconvenient. Therefore, how to solve the problem that suitcases cannot preserve fresh food is one of the issues that the suitcase industry needs to solve urgently.

The main purpose of the invention is to provide an improved luggage structure with a fresh-keeping function, which can maintain the structural strength of the luggage while providing a detachable fresh-keeping refrigerator.

Please refer to Figures 1 to 4, the first preferred embodiment of the present invention provides an improvement in the luggage structure with a fresh-keeping function, which mainly includes: a box body 10, a refrigerator unit 20 and a blocking assembly 30. Among them: The box body 10 has a front box shell 11, a rear box shell 12, a connecting piece 13 and a moving piece 14. The front box shell 11 and the rear box shell 12 can be combined together by the connecting piece 13, and the front box shell 11 and the rear box shell 12 jointly enclose a storage space (not shown). In this embodiment, the connecting piece 13 is a zipper. The moving piece 14 is arranged at the bottom of the box body 10 to assist the movement of the box body 10. In this embodiment, the moving member 14 is a plurality of rollers disposed at the bottom of the box body 10. The structure of the box body 10 is similar to that of a conventional suitcase, and its details are not described here. The characteristics of the present invention are as follows: the box body 10 has a storage space 15 inside, which is not connected to the storage space. In this embodiment, the storage space 15 is a space formed by the front box shell 11 of the box body 10 being recessed inward, and has a top side wall 150, a bottom side wall 151, an inner side wall 152 and an opening 153. The top side wall 150 and the bottom side wall 151 are parallel to each other and are at a predetermined distance from each other, and the inner side wall 152 is perpendicular to the top side wall 150 and the bottom side wall 151, and the two ends are respectively connected to the top side wall 150 and the bottom side wall 151. The opening 153 is provided on the surface of the box body 10, is parallel to the inner side wall 152, and is connected to the inside of the accommodating space 15.

The refrigerator unit 20 is detachably arranged in the accommodating space 15 of the box body 10. The refrigerator unit 20 is a square box body, which has a refrigerated space (not shown) and a refrigeration unit (not shown) inside, which is controlled to cool the refrigerated space so that the temperature in the refrigerated space is lower than a predetermined temperature. In this embodiment, the predetermined temperature ranges from 0°C to 7°C. In this embodiment, the refrigeration unit may include a power source, a refrigerator and a processor. The power source is electrically connected to the refrigerator and the processor to supply a current to a semiconductor refrigeration chip of the refrigerator, so that heat is transferred from a cold end of the semiconductor refrigeration chip to a hot end (thermoelectric effect), thereby achieving the effect of lowering the temperature. The surface of the refrigerator unit 20 is provided with a plurality of magnetic surfaces 21, and a movable door 22 is provided on one side of the refrigerator unit 20 for operation to open or close the refrigerated space. It should be added that in this embodiment, the power source is a detachable power source that can be removed or replaced when necessary. Thus, the power source can be removed from the refrigerator unit 20 before boarding the plane or during transportation to cope with the problem that batteries cannot be transported in the cargo hold of the aircraft.

The stopper assembly 30 includes a first stopper 31 and a second stopper 32. The first stopper 31 has a first pivot 310 at one end pivoted on the top side wall 150 of the accommodating space 15 and adjacent to the opening 153, so that the first stopper 31 can rotate between a first position and a second position. When the first stopper 31 rotates to the first position, the first stopper 31 rotates in a direction close to the top side wall 150 until it is approximately parallel to the top side wall 150. When the first stopper 31 rotates to the second position, the first stopper 31 rotates in a direction close to the opening 153 until it is approximately parallel to the opening 153 and closes the opening 153. Among them, one side of the first stopper 31 has a first magnetic attraction portion 311. The second stopper 32 in this embodiment is a square plate, and one end has a second pivot 320 pivotally disposed on the bottom side wall 151 of the accommodating space 15 and adjacent to the inner side wall 152, so that the second stopper 32 can rotate between a third position and a fourth position. When the second stopper 32 rotates to the third position, the second stopper 32 rotates in a direction close to the inner side wall 152 until it is approximately parallel to the inner side wall 152. When the second stopper 32 rotates to the fourth position, the second stopper 32 rotates in a direction close to the bottom side wall 151 until it is approximately parallel to the bottom side wall 151. One side of the second stopper 32 has a second magnetic attraction portion 321.

According to the above structural configuration, please refer to FIG. 3 , when the refrigerator unit 20 is to be placed in the accommodating space 15 of the box 10, the user moves the first stopper 31 to the first position and the second stopper 32 to the third position, so that the opening 153 of the accommodating space 15 is exposed to allow the refrigerator unit 20 to enter the accommodating space 15. When the refrigerator unit 20 is located in the accommodating space 15, the first magnetic attraction portion 311 of the first stopper 31 and the second magnetic attraction portion 321 of the second stopper 32 generate magnetic force to attract the magnetic attraction surfaces 21 of the refrigerator unit 20, so that the refrigerator unit 20 is fixed in the accommodating space 15 and is not easy to be separated from the box 10. In this way, the user can freely use the refrigerator unit 20 to refrigerate items while using the suitcase.

On the other hand, as shown in FIG. 4, the refrigerator unit 20 can also be removed from the box 10 for use. When the refrigerator unit 20 leaves the accommodating space of the box 10, the first stopper 31 and the second stopper 32 will rotate due to gravity, so that the first stopper 31 moves to the second position, and the second stopper 32 moves to the fourth position. At this time, the opening 153 of the accommodating space 15 will be closed by the first stopper 31. In this way, even if the refrigerator unit 20 is taken out for use, the first stopper 31 and the second stopper 32 can still support the accommodating space 15, and the structural strength of the box 10 can also be improved.

It should be added that in this embodiment, the accommodating space 15 is a cubic space with the same length, width and height, and the first stopper 31 and the second stopper 32 are two square plates with the same size.

Please refer to FIG. 5 and FIG. 6, which show the improvement of the luggage case structure with a fresh-keeping function provided by the second preferred embodiment of the present invention. Its structure is similar to that of the first preferred embodiment. However, in this embodiment, a heat preservation layer 40 is further included, which is a sheet made of heat preservation material. Two ends are respectively arranged on the surface of the box body 10 and at least a part thereof extends into the accommodating space 15 to provide the accommodating space 15 with an additional heat preservation effect. Specifically, the heat preservation layer 40 includes a first section 41, a second section 42 and a third section 43. The second section 42 is connected to the first section 41 and the third section 43. The first section 41 is attached to a side of the first stopper 31 away from the top side wall 150. The second section 42 is attached to a side of the second stopper 32 away from the inner side wall 152. The third section 43 is attached to the bottom side wall 151. The heat preservation layer 40 is used to provide additional heat preservation effect for the refrigerator unit 20 and/or the accommodating space 15.

As shown in FIG. 5 , when the refrigerator unit 40 is in the accommodation space 15 and the first stopper 31 is in the first position and the second stopper 32 is in the third position, the first section 41 is generally parallel to the top side wall 150, so that the first stopper 31 is located between the top side wall 150 and the first section 41. The second section 42 is generally parallel to the inner side wall 152, so that the second stopper 32 is located between the inner side wall 152 and the second section 42. The third section 43 is generally parallel to the bottom side wall 151 and is located above the bottom side wall 151. Thus, the first section 41, the second section 42 and the third section 43 of the heat preservation layer 40 are attached to the surface of the refrigerator unit 20.

As shown in FIG. 6 , when the refrigerator unit 20 leaves the accommodating space 15 and the first stopper 31 is located at the second position and the second stopper 32 is located at the fourth position, the first section 41 is generally parallel to the opening 153, so that the first stopper 31 and the first section 41 simultaneously close the opening 153. The second section 42 and the third section 43 are overlapped on the bottom side wall 151, and the second section 42 and the third section 43 are simultaneously sandwiched between the second stopper 32 and the bottom side wall 151.

In summary, the improvement of the luggage structure with a fresh-keeping function provided by the present invention can be provided by the design of the detachable refrigerator unit. The refrigerator unit can be stored in the luggage to provide a refrigeration function at ordinary times, and the refrigerator unit can be taken out of the luggage and carried when it is necessary to go out. On the other hand, the blocking component provides a fixed function when the refrigerator unit is stored in the storage space; after the refrigerator unit leaves the storage space, the blocking component can block the opening after rotation and strengthen the structural strength of the luggage.
