Four output valve structure

The "four-output gas valve structure" of the present invention relates to a gas supply device for an air bed, and more particularly to a technical field having a four-output gas valve capable of achieving various gas supply changes.

If people are lying on a hospital bed for a long time because of illness, they tend to be forced by the body for a long time, causing the body to contact with the bed surface due to poor blood circulation for a long time, and tissue hemorrhoids. In order to avoid the patient getting hemorrhoids, the most effective way is to let the patient lie down and exchange the inflatable air bed. The exchange type air bed is divided into airbag strips with exchangeable inflation and exhaust, which can be charged and exhausted by gas exchange. The patient's body reaches an alternating and temporarily untouched decompression effect, thereby reducing the chance of acne.

Although the inventor has previously proposed and obtained a number of domestic and foreign patents, such as Taiwan's first case No. I400403, the inventor has not been complacent and continued to research and develop. The inventors have found that in the past, a single gas valve can only change the gas supply in turn for the three-zone airbag. If the four-zone air-conditioning change is to be supplied, the two sets of air valves must be used, so that the cost is greatly increased and the volume is also increased. Double, very unsatisfactory.

The reason is that the inventor has no way to use the single air bed. One gas valve reached a four-zone airbag to improve the lack of gas supply changes, so the completion of the case.

The "four-output gas valve structure" of the present invention has the main purpose of using the single gas valve to achieve the purpose of making the air supply or deflation state of the airbags of the four regions differently arranged and combined. In this way, the case can achieve the previously unattainable effect by maintaining only a single gas valve, and it is obviously improved in progress and efficiency.

To achieve the above objective, the present invention specifically provides that the valve structure includes a first body and a second body.

Preferably, the first body comprises one or two intake pipes, one or two exhaust pipes, an intake chamber, four gas delivery ports and one or two exhaust chambers. Wherein the intake pipe has an outer end connected to a pump, and an inner end is connected to the inlet chamber. The air inlet chamber has a ring shape, and an edge surface is open; the first body is provided with a gas outlet A, a gas outlet B, a gas outlet C and a fourth equidistant position. The gas outlet D, the outer end of each gas outlet is connected to a tube structure for connecting to the airbags of the four regions of the air bed; and the first body is provided with two exhaust chambers, and the exhaust chambers are It is connected to each exhaust pipe. Each of the air inlets, the inlet chamber and the exhaust chamber are independent of each other and are not in communication with each other.

Preferably, the second body includes an air intake space on the inner ring, and a space for the partition is disposed on the outer periphery of the air space, and an outer space is disposed on the outer ring; and the air space is further provided. The first exhaust portion, a second intake portion and a third intake portion are included; the exhaust space further includes a first exhaust portion, a second exhaust portion, and a third row a gas portion and a fourth exhaust portion.

Preferably, the first body is centrally disposed with a first shaft hole, and the second body is centrally disposed with a second shaft hole. The first body is attached to the second body, and the second body is opposite to the second body. Rotating on the first body, the case is specifically designed to have an angle of 30 degrees per rotation.

Referring to FIG. 8 again, the second body 2 is rotated by another 30 degrees, so that air enters the intake chamber 13 from the intake pipe 11 of the first body 1 and enters the intake space 21 of the second body 2. At this time, the air inlet A 14 and the air inlet D 17 are both connected to the air intake space 21 and have air supply, but the air inlet B 15 and the air outlet C 16 are connected to the exhaust space 22, so the original is located at the transmission. The air port B 15 and the space inside the air port C 16 are transferred to the exhaust pipe 12 via the exhaust chamber 18 to be exhausted.

Referring again to the ninth figure, the second body 2 is rotated by another 30 degrees, so that air enters the intake chamber 13 from the intake pipe 11 of the first body 1 and enters the intake space 21 of the second body 2. At this time, the air inlet B 15 and the air outlet D 17 are both connected to the air intake space 21 and have air supply, but the air inlet A 14 and the air outlet C 16 are connected to the exhaust space 22, so the original air is located at the input. The air port A 14 and the space inside the air port C 16 are transferred to the exhaust pipe 12 via the exhaust chamber 18 to be exhausted.

Referring again to the tenth figure, the second body 2 is rotated by another 30 degrees to allow air to enter the intake chamber 13 from the intake pipe 11 of the first body 1 and enter the intake space 21 of the second body 2. At this time, the air inlet A 14 , the air inlet B 15 , the air inlet C 16 and the air outlet D 17 are connected to the air inlet 21 All have air supply.

Referring to FIG. 11 again, the second body 2 is rotated by another 30 degrees to allow air to enter the intake chamber 13 from the intake pipe 11 of the first body 1 and enter the intake space of the second body 2. 21, at this time, the air inlet A 14 and the air outlet B 15 are both connected to the air intake space 21 and have air supply, but the air inlet C 16 and the air outlet D 17 are connected to the exhaust space 22, so the original location is The space inside the gas delivery port C 16 and the gas delivery port D 17 is transferred to the exhaust pipe 12 via the exhaust chamber 18 to be exhausted.

Referring to FIG. 12 again, the second body 2 is rotated by another 30 degrees, so that air enters the intake chamber 13 from the intake pipe 11 of the first body 1 and enters the intake space of the second body 2. 21, at this time, the air inlet A 14 and the air inlet C 16 are both connected to the air intake space 21 and have air supply, but the air inlet B 15 and the air outlet D 17 are connected to the exhaust space 22, so the original location is The air inlet B 15 and the space inside the air outlet D 17 are transferred to the exhaust pipe 12 via the exhaust chamber 18 to be exhausted.

Referring to FIG. 13 again, the second body 2 is rotated by another 30 degrees, so that air enters the intake chamber 13 from the intake pipe 11 of the first body 1 and enters the intake space of the second body 2. 21, at this time, the air inlet A 14 , the air inlet B 15 , the air inlet C 16 and the air outlet D 17 are both connected to the air inlet 21 and have air supply.

Referring to FIG. 14 again, the second body 2 is rotated by another 30 degrees to allow air to enter the intake chamber 13 from the intake pipe 11 of the first body 1 and enter the intake space of the second body 2. 21, at this time, the air inlet B 15 and the air outlet C 16 are both connected to the air intake space 21 to supply air, but the air inlet A 14 and the air outlet D 17 are connected to the exhaust space 22, so the original location is The space inside the air inlet A 14 and the air outlet D 17 will be transferred via the exhaust chamber 18 The exhaust pipe 12 is exhausted.

Referring again to the fifteenth figure, the second body 2 is rotated by another 30 degrees to allow air to enter the intake chamber 13 from the intake pipe 11 of the first body 1 and enter the intake space of the second body 2. 21, at this time, the air outlet B 15 and the air outlet D 17 are both connected to the air intake space 21 and have air supply, but the air inlet A 14 and the air outlet C 16 are connected to the exhaust space 22, so the original location is The air inlet A 14 and the space inside the air inlet C 16 are transferred to the exhaust pipe 12 via the exhaust chamber 18 to be exhausted.

It can be seen from the above that the gas valve structure of this case, with a special and clever design, can make the gas supply port A 14 , the gas transmission port B 15 , the gas transmission port C 16 and the gas transmission port D 17 have gas supply and partial rotation. Different changes such as gas supply or partial rotation and exhaust can make an air bed separated into four different areas of airbag strips or airbag blocks, which can produce variable filling and deflation changes, which can effectively prevent the occurrence of hemorrhoids in patients.
