Passengers pay more attention to the problem of bacterial cross-infection when using toilets. For this reason, some passengers will wipe the toilet ring with a paper towel before using the toilet, or put on a disposable toilet pad. This method will increase the use time of the toilet, reduce the efficiency of toilet use and bring a bad use experience to passengers. At present, there are toilets that can automatically replace toilet cleaning covers, which can overcome the above problems. However, the current toilets that can automatically replace toilet cleaning covers have the following problems:

[0058] The Hall sensor may be an existing device, and its counting sensing component 18 and data processing module 19 are not described in detail here.

[0059] like Figure 4 As shown, the counting roller 16 includes a rotating shaft 16-1. Preferably, the rotating shaft 16-1 is made of stainless steel. A plurality of rubber rings 16-2 are sleeved on the rotating shaft 16-1 along the axial direction. The rubber rings 16-2 are used to contact with the sanitary cover to prevent slipping.

[0060] A positive magnet and a negative magnet are arranged on the end surface of the rubber ring 16 - 2 located at the inner end, and the positive magnet and the negative magnet are used to cooperate with the counting induction component 18 of the Hall sensor.

[0061] like Figure 5-Figure 7 As shown, the seat ring assembly 2 includes a lower seat ring 2-1 and an upper seat ring 2-2 located above the lower seat ring. One end of the lower seat ring 2-1 is connected to the output shaft of the seat ring flip motor 15. Specifically, as shown in Figure 8-Figure 9 As shown, the output shaft of the seat ring flipping motor 15 is installed with an inner rotating insert 23, and the lower seat ring 2-1 is installed with an outer rotating insert 17. The outer rotating insert and the inner rotating insert 23 are sleeve-connected, and the two opposite outer side surfaces of the inner rotating insert are planes parallel to each other. Correspondingly, the middle hole of the outer rotating insert has two opposite parallel plane hole surfaces. This arrangement can prevent the seat ring assembly from slipping when flipping.

[0062] Preferably, the outer rotating insert 17 and the inner rotating insert are made of copper.

[0063] In other embodiments, the output shaft of the seat ring flipping motor 15 is directly fixedly connected to the lower seat ring 2-1.

[0064] The other end of the lower race 2-1 is rotatably connected to the bearing seat 20 via a shaft.

[0065] The shape of the upper seat ring 2-2 matches the shape of the lower seat ring 2-1. A connecting block 2-3 is provided on the bottom surface of one end of the upper seat ring close to the bearing seat. The connecting block 2-3 is inserted into the groove 2-4 provided on the top surface of the lower seat ring 2-1. The connecting block 2-3 is connected to the lower seat ring 2-1 by bolts to realize the connection between the upper seat ring 2-2 and the lower seat ring 2-1.

[0066] In this embodiment, the sanitary sleeve is sleeved on the upper seat ring 2-2, and the connecting block 2-3 simultaneously cuts the sanitary sleeve, which enables the sanitary sleeve to move smoothly and cuts the used sanitary sleeve to avoid reuse.

[0067] The upper seat ring 2-2 is composed of an upper seat ring upper cover 2-2-1 and an upper seat ring lower cover 2-2-2 through friction welding, and the connecting block 2-3 is fixed on the bottom surface of the upper seat ring upper cover 2-2-1, and the corresponding upper seat ring lower cover 2-2-2 is provided with a hole for the connecting block to pass through, and a heating element is fixed in the cavity formed after the upper seat ring 2-2-1 cover and the upper seat ring lower cover 2-2-2 are fixed, and the upper seat ring upper cover 2-2-1 and the upper seat ring lower cover 2-2-2 are connected by friction welding, without screws and nuts, and are fully enclosed, more beautiful and comfortable, and the heating element adopts an electric heating plate, and the power supply line of the electric heating plate extends into the inner space of the lower seat ring through the opening set near the end of the bearing seat of the upper seat ring lower cover 2-2-2, and then enters the outer shell 3 through the inner space of the lower seat ring and is connected with the control circuit board 10, which ensures that the wiring is internal wiring, making the appearance more beautiful.

[0068] The upper seat ring upper cover 2-2-1 is also provided with a sensing element 21, which is a pressure sensor. The signal line of the sensing element 21 passes through the upper seat ring lower cover 2-2-2 and enters the internal space of the lower seat ring 2-1, and then enters the outer shell 3 and is connected to the circuit control board 10.

[0069] The setting position of the sensing element 21 is 166 mm away from the front end of the upper seat ring 2-2, and children, the elderly and adults can all touch it in actual use, which can minimize the problem of the heating function not being triggered.

[0070] Furthermore, the bottom surface of the lower seat ring 2-1 is provided with a plurality of anti-collision buffer pads 22. Preferably, five anti-collision buffer pads 22 are provided, and the five anti-collision buffer pads 22 are arranged at equal intervals to prevent the toilet bowl 4 of the toilet from being crushed.

[0071] In this embodiment, the control circuit board is also connected to the train's TCMS system, the feces collection control system and the toilet door system, and can be linked with the train's TCMS system, the feces collection control system and the toilet door system, thereby improving the intelligence level of railway passenger car toilets and meeting the high-end needs of railway EMU passengers. The train's TCMS system, the feces collection control system and the toilet door system are built-in systems of the train and will not be described in detail here.

[0072] The seat ring assembly includes two layers, an upper seat ring and a lower seat ring. It has high structural strength and is not easily damaged, and is suitable for the high-frequency use requirements of railway passenger cars.

[0073] The contactless toilet cover of this embodiment has a cover flip motor connected to the cover through a connecting piece, and is also provided with a radar sensor connected to the control system. When the radar sensor senses a user, the cover can be automatically opened by the cover flip motor without manual opening. The entire toilet use process is completely contactless, reducing the risk of cross infection. The cover flip motor connected to the cover is located in the power compartment, and can be improved on the basis of the current toilet cover that can automatically replace the toilet cover. There is no need to occupy additional external space of the toilet, and the improvement is convenient.

[0074] Example 2

[0075] This embodiment provides a toilet, such as Figure 10-11 As shown, it includes a toilet body, which includes a toilet collecting tank 4 and a water tank. The toilet collecting tank is provided with the contactless toilet cover for railway passenger cars described in Example 1. The toilet collecting tank 4 and the water tank can adopt the existing technology, and their specific structure is not described in detail here. A pressure sensor is provided on the button of the water tank, and the pressure sensor is connected to the control circuit board.

[0076] Example 3

[0077] This embodiment provides a working method of the toilet described in Embodiment 2:

[0078] Put the cleaning sleeve on the core shaft in the new cleaning sleeve bin, then lead the movable end of the cleaning sleeve out of the new cleaning sleeve bin, put the cleaning sleeve on the upper seat ring, pull the movable end of the cleaning sleeve along the upper seat ring, the movable end of the cleaning sleeve passes under the counting roller and over the counting roller, enters the cleaning sleeve recovery bin and is fixed to the core shaft in the cleaning sleeve recovery bin, the rubber ring of the counting roller contacts the cleaning sleeve, and the cleaning sleeve is cut at the connecting block.

[0079] When in the standby state, the cover plate and the seat ring assembly are both in a dropped and closed state.

[0080] When the radar detector detects that someone enters within 80cm in front, it sends a signal to the control circuit board. After receiving the signal, the control circuit board controls the cover flip motor to work, and drives the cover to flip upward through the connecting piece and open automatically. After the first set time, the seat ring flip motor works to drive the seat ring assembly to flip upward.

[0081] Preferably, the first set time is 2 seconds.

[0082] When the user uses the seat, the user triggers the infrared sensor, which senses the user and sends a signal to the control circuit board. The control circuit board controls the seat flip motor to work, driving the seat assembly to flip downward until the anti-collision cushion fits with the toilet body.

[0083] At this time, the user can use the toilet. After the user sits on the upper seat, the sensing element senses the user and then sends a signal to the control circuit board. The control circuit board starts the electric heating plate to make the upper seat in a set constant temperature state to meet the user's comfort requirements. After use, the user presses the button on the water tank to complete the flushing of the toilet. After the pressure sensor on the button detects the pressure, it sends a flushing signal to the control circuit board. The control circuit board controls the core shaft drive motor to work, and the core shaft in the toilet cover recovery bin rotates to pull the toilet cover to replace the toilet cover.

[0084] The Hall sensor detects the movement distance of the sanitary cover. When the Hall sensor detects that the sanitary cover moves the length of an upper seat ring, it sends a signal to the control circuit board. The control circuit board controls the spindle drive motor to stop working, and the number of times the sanitary cover is used displayed on the display screen is +1.

[0085] In this embodiment, the design number of times a roll of toilet cover is about 50 times. When the Hall sensor records the specified length, that is, the remaining toilet cover reaches the set number of times (this value can be set manually), the control circuit board outputs a warning signal to the train's TCMS system. When the Hall sensor records that the toilet cover has been used up, it outputs a signal to the train's TCMS system to remind the crew to replace the toilet cover with a new one.

[0086] It is understandable that a manual button is provided on the housing, and the manual button is connected to the control circuit board. The mandrel drive motor can be started by the manual button to complete the replacement operation of the sanitary cover.

[0087] When the pressure sensor of the button on the water tank detects the pressure for the second set time, the cover flip motor drives the cover to rotate downward and the cover is closed. The second set time is greater than the time required to replace the sanitary cover once. It can be set according to actual needs and is not described in detail here.

[0088] When the infrared sensor does not sense the user, after the control circuit board receives the flushing signal detected by the pressure sensor, after the third set time, the seat ring flip drive drives the seat ring assembly to flip down, and after the fourth set time, the cover plate flip drive drives the cover plate to flip down and close.

[0089] The third setting time and the fourth setting time can be set according to actual needs, preferably 2-6s.

[0090] By adopting the working method of this embodiment, the entire toilet use process is completely contact-free, reducing the risk of cross infection.

[0091] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
