The box cover 92 is sealedly connected to the upper opening of the embedded box 91 and is provided with a liquid filling port 921 connected to the liquid reservoir 21. A switch element for opening and closing the liquid filling port 921 is also provided. The switch element is specifically a push-type pop-up button assembly 10, which can be turned on and off by pressing.

[0045] The present invention further includes a lighting module 20, which is mounted on the inner top surface of the box cover 92 and electrically connected to the electronic control assembly 3 to provide a light indication of the operating status of the flush valve 4 and the foam module 2. The light is emitted through corresponding areas of the box cover 92. Specifically, the lighting module 20 is mounted at the front end of the box cover 92, but the mounting location of the lighting module 20 is not limited to this.

[0046] The integrated box 9 further includes a support plate 93, which is connected to the opening of the embedded box 91 and is located below the box cover 92. The sensing module 5 is connected to the support plate 93. Specifically, the left and right sides of the sensing module 5 are respectively provided with mounting lugs 52, which are locked to the support plate 93 using fasteners. The box cover 92 is tilted with the front lower and the back higher. The end face of the bell mouth 51 of the sensing module 5 is tilted and fits the inner top surface of the box cover 92. Figure 8 、 Figure 9 In this way, the box cover 92 can ensure the sensing effect of the sensing module 5 without opening a sensing window, ensuring the integrity of the product, while avoiding the risk of privacy exposure caused by the user worrying about the presence of a camera in the sensing window.

[0047] The electric control component 3 is installed in an independent sealed chamber 911 in the embedded box 91, which has a good waterproof effect. Figure 11 shown.

[0048] The present invention also includes a remote control and / or a water pressure sensor 7. The remote control communicates wirelessly with the electronic control component 3 to control whether the flushing valve 4 and / or the foam module 2 are working or not. The remote control is a self-generating remote control button 30; the water pressure sensor 7 is arranged at the water inlet end of the flushing valve 4 to detect the inlet water pressure, and the water pressure sensor 7 is electrically connected to the electronic control component 3, so that the electronic control component 3 controls the flushing time of the flushing valve 4 according to the water pressure.

[0049] When installing a squat toilet according to the present invention, the squat toilet body 1 and the embedded box 91 of the integrated box 9 are preliminarily installed by pre-embedding, and the rear end of the embedded box 91 is connected to the water supply of the building pipeline, and an electric wire pipe is reserved for power supply; then, the foam module 2, the electric control component 3, the flushing valve 4, the sensor module 5, etc. are installed in the embedded box 91; finally, the box cover 92 is covered.

[0050] The working principle of the squat toilet of the utility model is as follows:

[0051] When the sensor module 5 senses that the user is urinating in the squat toilet body 1, the light module 20 lights up steadily to remind the user that they are in the sensing area and can urinate normally. The foam module 2 does not produce foam. After the user leaves, the flush valve 4 is activated, and the light module 20 changes to a breathing light mode. After flushing is completed, the breathing light turns to a steady light and turns off after 30 seconds.

[0052] When the sensor module 5 senses that the user is in the defecation position of the squat toilet body 1, the light module 20 lights up steadily to remind the user that they are in the sensing area and can use the toilet normally. At the same time, the electronic control component 3 activates the foam module 2 to produce foam. During the foaming process, the light of the light module 20 switches to a breathing light mode and returns to a steady light after the foaming is completed. After the user leaves, the flush valve 4 is activated, and the light of the light module 20 switches to a breathing light mode. After the flushing is completed, the breathing light returns to a steady light and turns off after 30 seconds.

[0053] The utility model is equipped with a self-generating remote control button 30, which can be freely installed according to user requirements and does not require power supply. Pressing the button activates flushing and / or foaming. When the water pressure sensor 7 at the front end of the flush valve 4 detects low water pressure, it sends a signal to the main control board, which automatically adjusts the flushing time to ensure a good flushing function.

[0054] The foam module 2 operates as follows: When foaming is needed, the electronic control assembly 3 controls the water inlet control valve 24 to open, allowing water to enter the mixing chamber of the mixer 22 and mix with the soap solution in the mixing chamber. Water is then transferred through a pipe to the foam generator 25. The foam generator 25 draws air through the Venturi principle to produce foam. Once generated, the foam is output to the foam outlet connector 62 of the two-in-one connector 6. From there, the foam is ejected into the toilet bowl of the squat toilet body 1, completely covering the water seal. After the user leaves the toilet, the liquid extraction pump 23 starts, extracting the soap solution through the pipe and transferring it to the mixing chamber of the mixer 22, ready for the next foaming, reducing the waiting time for the next user to use the foam.

[0055] The capacity of the liquid reservoir 21 is large and can be used for 2000 times. After use, the bounce button assembly 10 can be pressed to partially bounce the bounce button assembly 10. After the whole assembly is taken out, Figure 12 As shown, in this way, liquid can be added directly from the liquid filling port 921, which is convenient and quick. The bounce button assembly 10 is provided with a sealing ring to prevent sewage from entering the liquid filling port 921 when cleaning.

[0056] The utility model provides a squat toilet that can achieve foaming without an air pump, is more energy-efficient and environmentally friendly, and is conducive to reducing the overall working noise. The utility model further provides a sensing module 5, so that the utility model can achieve intelligent control, which can greatly improve the convenience of user use. In particular, the sensing port of the sensing module 5 is a trumpet mouth 51 made of metal material, which can be used to enhance the signal strength of the sensing module 5 and limit the sensing range of the sensing module 5, to avoid sensing beyond the range of the squat toilet pit, causing false triggering, and at the same time, the sensing signal can increase the sensing range in the vertical direction through the notch 511 of the trumpet mouth 51, to ensure that the squatting state can also be detected. The utility model further provides an integrated box 9, which integrates the foam module 2, the flush valve 4, etc., so that the overall structure is more compact and simple, and is easy to assemble and maintain later.

[0057] The squat toilet of the present invention does not involve parts (such as the foamer 25, the specific structure and working principle of the bounce button assembly 10, etc.) that are the same as those in the prior art or can be implemented using the prior art.

[0058] The above embodiments are only used to further illustrate a squat toilet of the present invention, but the present invention is not limited to the embodiments.
