Description

Self-cleaning seat toilet

technical field

The invention relates to a water closet (that is, a water closet), in particular to a toilet with the function of automatic cleaning of the seat cushion, which is used in public toilets.

Background technique

With its comfortable and hygienic advantages, toilets are gradually replacing squatting toilets in public toilets. Then the toilet seat cushion pollution caused by the improper use of some users makes users and cleaning staff quite a headache, and this has become a long-term and urgent problem that people are looking forward to solving.

There are mainly two types of existing technical solutions:

1. The use of toilet seat paper has the following disadvantages: 1. Paper waste is seriously difficult to manage and is not environmentally friendly. 2. Thin seat paper is difficult to deal with deep pollution (such as urine on the seat);

2. A toilet that automatically cleans the seat cushion, such as the patent application number CN201220657560, which is designed with an electrical device that uses microwaves to clean the seat cushion; there are also some inventions that use water flow or high-pressure gas to flush. The common shortcoming of these inventions is complex structure and high cost.

Technical bias in existing technologies:

These technical prejudices trap people's innovative thinking, and there are two main types:

Prejudice 1: When cleaning the cushion, the cushion is always fixed, and the cleaning tool moves (such as a reciprocating brush to scrub the cushion), or the cleaning medium (such as intense water flow or high-pressure gas) directly washes the cushion;

Prejudice 2: Public toilet seat cushions are still designed to be stored after use (the most common is to lift them up). Cushion storage was originally designed to prevent men from polluting the seat cushions with urine when used in private houses, but public toilets have independent men's urinals, so this design is no longer necessary. Moreover, people are not willing to touch the seat cushion of the public toilet toilet with their hands at all.

Contents of the invention

The invention aims to overcome the prejudice of traditional technology, find a new way and adopt a new solution. When automatically cleaning the toilet seat cushion, it does not rely on electricity or high voltage, and does not need a control chip. It creates a public toilet seat with simple and durable structure and excellent effect. toilet.

1. Innovative ideas:

The idea of the present invention is to make the cleaning tool (such as a brush) fixed and the cushion move. For this reason, we choose a closed ring-shaped hose to replace the traditional hard cushion. The hose can be filled with gas or liquid. The cushion will deform and fit the buttocks under the pressure of the human buttocks, making people feel comfortable.

The hose is driven around the toilet using a drive wheel. The driving force of this driving wheel is set off by the user or depresses the kinetic energy transmission of the toilet lid.

The technical solution based on this idea is shown in Figure 1. The self-cleaning seat toilet is mainly composed of: a closed ring-shaped hose cushion (1) with iron particles inside, and a hose that is pressed on the hose cushion to drive the hose to rotate around the toilet. The pressure belt wheel (2), the decontamination brush (4) used to remove the stains on the hose, the wiper brush (3) used to dry the water stains on the hose, installed on the toilet seat to absorb the hose build The magnet (5) of the magnetic track, the nozzle (6) that is connected to the toilet water tank to spray water to flush the stains on the decontamination brush (4) into the toilet; and the toilet cover, the toilet seat and the water tank.

As shown in accompanying drawing 3, gear is housed on the toilet cover, and this gear engages a gear transmission pinch wheel that is installed on the toilet seat to rotate, thereby makes hose seat cushion rotate around the toilet.

Of course, the hose cushion can also be driven in other ways:

1. For example, use the spring to store the mechanical energy of the toilet lid, and then release it to the pressure pulley. 2. Use the battery and the generator to store the mechanical energy of the toilet cover and then use the electric motor to drive the pinch roller. 3. Directly use electric power (motor) to drive the pinch roller. 4. Directly provide a hand handle to allow users to directly rotate the pinch wheel. etc. include but are not limited to various existing transmission schemes mentioned above.

Important points that must be realized: there is a need for a track between the hose seat cushion and the toilet seat to regulate its rotation. If a groove nested hose designed on the toilet seat is used as a track, its disadvantages are obvious: it is not reliable and the groove is easy to deposit urine and other stains. To this end, we propose a solution to solve this problem: use magnets to create magnetic tracks.

2. Magnetic track:

The tube of the hose seat cushion is stuffed with iron particles, and a magnet is installed on the toilet seat, and the magnet attaches the hose seat cushion to the toilet seat.

It is obvious from accompanying drawing 2 that the end surface of the toilet seat carrying the hose cushion (that is, the contact surface between the toilet seat and the cushion) is inclined towards the inside of the toilet, and its shape is similar to a stadium stand.

This design serves two purposes:

1. Under the heavy pressure of the human buttocks, the hose not only deforms under the downward pressure, but also expands outward due to the extrusion of the buttocks. The inner slope is designed to withstand the extrusion force and prevent the hose from expanding;

2. The inner slope of the end surface can drain the dirt (such as urine) into the toilet.

3. Automatic cleaning process of hose cushion:

Accompanying drawing 1 is the schematic diagram of the automatic cleaning process of the hose cushion of the present invention. In the picture:

1 is a closed ring-shaped hose cushion with iron particles inside; 2 is a pressure wheel that presses on the hose cushion to drive the hose to rotate around the toilet; 3 is a wiper brush used to dry the water stains on the hose ; 4 is a decontamination brush used to remove stains on the hose; 5 is a magnet installed on the toilet seat to absorb the hose to create a magnetic track; 6 is a cleaning nozzle, which is aimed at the decontamination brush to spray water to clean and remove Stain on the stain brush, flush the stain into 7. The nozzle is connected to the toilet tank and is controlled by the toilet flush valve, that is, when people flush the toilet, the nozzle flushes the decontamination brush; 7 is the sewage guide pool connected to the toilet, where the stains washed down by 6 are collected and introduced In the toilet.

It should be noted that the gear or the pinch pulley should be covered with a one-way bearing. For example, when the toilet cover is pressed down, the hose is driven to rotate. Then, under the action of the one-way bearing, turning the toilet cover up will not cause the hose to rotate. That is to say, the one-way rotation of the hose cushion is limited by the one-way bearing, and the two-way rotation is prohibited.

Limit the one-way rotation of the hose: Obviously, the aforementioned one-way bearing to limit the one-way rotation of the hose cushion is also for the purpose of regulating the cleaning sequence of the hose, that is, it is decontaminated first, and then wiped to dehumidify. Reverse the order.

Further, a sterilizing device can also be arranged beside the wiper brush, for example, an ultraviolet germicidal lamp irradiates and sterilizes the hose. Further, before the decontamination brush, a soap liquid device can also be provided to spray soap liquid on the hose to facilitate decontamination.

Further, a soap liquid device can be arranged beside the cleaning nozzle, and soap liquid is mixed into the water flow to facilitate decontamination. Further, the hose can be filled with liquid, and a heating device, such as an electromagnetic heating device, can be used to heat the hose to a comfortable temperature, so that the buttocks can be warmed even in cold seasons.

Advantages of the invention:

The present invention not only solves the problems mentioned in the aforementioned background technology, but also has the following unexpected advantages: 1. The hose cushion can be deformed under the pressure of the buttocks, so it fits the buttocks more comfortably; 2. The inside of the hose cushion is full of Liquid, so it can be easily heated to warm the buttocks for extra comfort.

Description of drawings:

Fig. 1 is a principle diagram of automatic cleaning of a hose seat cushion; Fig. 2 is a vertical sectional view of the toilet according to the present invention; Fig. 3 is a side view of the toilet with the kinetic energy driving the hose of the toilet lid.

Detailed ways:

Accompanying drawing 3 has shown a design example that utilizes the toilet lid kinetic energy to drive the hose cushion to run, 309 among the figure is the toilet lid, and 1 is the hose cushion, and the hose cushion is clamped between two pinch rollers. The toilet lid is equipped with gears that engage a geared pinch wheel mounted on the toilet seat to rotate, thereby causing the hose seat to rotate around the toilet. Accompanying drawing 2 is a vertical sectional view of the toilet, showing the magnetic track created by the magnet and the hose seat cushion with iron particles inside: 5 in the figure is the magnet installed on the toilet seat; 208 is the toilet seat; 1 is the hose cushion ; 200 are iron particles in the hose.

Working process: the hose cushion in the accompanying drawing 1 is driven by the drive wheel and rotates counterclockwise around the toilet, and the stains on the hose are first brushed off by the decontamination brush (while the decontamination brush is polluted). The hose may be wet at this time as the brushes are often rinsed with water. After the hose passes through the wiper brush, the water on the hose is scraped off and transferred out of the treatment area, so that the human buttocks can enjoy it in a clean and dry state.
