DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-6 This application is described in further detail.

[0030] Embodiment 1

[0031] An automatic flushing and odor-proof smart toilet, refer to Figure 1 and Figure 2 As shown, the toilet body 1 includes a toilet body 1 and a toilet cavity 2 arranged on the toilet body 1, a siphon pipe 3 connected to the bottom of the toilet cavity 2 is arranged on the toilet body 1, a toilet cover 4 for covering the toilet cavity 2 is rotatably installed on the toilet body 1, a flush pipe 5 is arranged in the toilet body 1, one end of the flush pipe 5 is used for connecting to a tap water pipe, and the other end of the flush pipe 5 is connected to the toilet cavity 2, and a flush solenoid valve 6 is installed on the flush pipe 5.

[0032] When the flush solenoid valve 6 is opened, tap water can enter the toilet cavity 2 through the flush pipe 5. When the water in the toilet cavity 2 reaches a certain amount, the position of the water in the toilet cavity 2 is higher than the highest bending point of the siphon pipe 3. The water will be drawn away in the toilet cavity 2 due to the siphon effect of the siphon pipe 3, thereby realizing the discharge of the water. In the final stage of the siphon, part of the air in the toilet cavity 2 will also be taken away.

[0033] In the present application, a human body sensor 7 is arranged outside the toilet body 1. The human body sensor 7 adopts a pyroelectric infrared sensor. The human body sensor 7 is arranged at the front end of the toilet body 1. When a human body approaches the toilet body 1, the human body sensor 7 can sense the presence of the human body.

[0034] The toilet body 1 is provided with a toilet cover sensor 8 at the edge of the toilet cavity 2. Specifically, the toilet body 1 is provided with a mounting groove 9 at the edge of the toilet cavity 2. The mounting groove 9 is close to the position where the toilet cover 4 is rotatably connected. The toilet cover sensor 8 is embedded in the mounting groove 9. The toilet cover sensor 8 adopts a touch switch or a proximity sensor. Among them, the bottom of the toilet cover 4 is provided with a contact end 10 that cooperates with the toilet cover sensor 8. When the toilet cover 4 is covered on the toilet cavity 2, the contact end 10 at the bottom of the toilet cover 4 will contact the toilet cover sensor 8 to trigger the toilet cover sensor 8.

[0035] A main control chip is provided in the toilet body 1, and the main control chip can be a single chip microcomputer. The main control chip is electrically connected to the human body sensor 7, the lid sensor 8 and the flush solenoid valve 6. When the lid sensor 8 detects that the toilet lid 4 is closed and the human body sensor 7 detects that a human body is approaching, the main control chip controls the flush solenoid valve 6 to open for flushing. When the lid sensor 8 detects that the toilet lid 4 is closed but the human body sensor 7 does not detect that a human body is approaching, the main control chip controls the flush solenoid valve 6 to open for flushing at a preset period. In one embodiment, the preset period is 1 hour. The specific preset period can be set according to the actual usage scenario, and no specific setting is made in this embodiment.

[0036] It is worth noting that by setting the opening time of the flush solenoid valve 6 controlled by the main control chip, for example, the main control chip controls the flush solenoid valve 6 to close after opening for 5 seconds, so that the amount of water in the toilet cavity 2 can reach the flushing action.

[0037] Among them, the main control chip is connected to the remote control through wireless communication. The remote control is provided with control buttons. The control buttons can be set as function buttons of the smart toilet. For example, a flush button is provided on the remote control. By triggering the flush button, the flush solenoid valve 6 can be controlled by the main control chip to complete the flushing action.

[0038] By setting the above-mentioned flushing method, the present application can avoid the accumulation of odor in the toilet cavity 2 after the toilet lid 4 is closed and affecting the subsequent use of the toilet in public places, and because the toilet cavity 2 is flushed at a preset cycle in public places, not only can the odor in the toilet cavity 2 be flushed away, but the toilet cavity 2 can also be kept clean, avoiding dirt remaining in the toilet cavity 2 due to people forgetting to flush.

[0039] In the present application, the odor in the toilet cavity 2 is filled into the siphon pipe 3 through flushing, so that the odor will not escape into the space outside the toilet cavity 2, thereby achieving a deodorizing effect.

[0040] Embodiment 2

[0041] Based on Example 1, refer to Figure 3 and Figure 4 As shown, a water tank 11 is arranged in the toilet body 1, and the water tank 11 has a water inlet and a water outlet, and a water inlet pipe 12 is connected to the water inlet, and a water inlet solenoid valve 13 is installed on the water inlet pipe 12, and the water inlet pipe 12 is connected to the tap water pipe. A flushing pipe 5 is connected to the water outlet of the water tank 11, and a flushing booster pump 14 is installed between the flushing solenoid valve 6 and the water outlet, and the water inlet solenoid valve 13, the flushing solenoid valve 6 and the flushing booster pump 14 are electrically connected to the main control chip.

[0042] When the toilet lid sensor 8 detects that the toilet lid 4 is closed and the human body sensor 7 detects that a human body is approaching, the main control chip controls the flushing solenoid valve 6 and the flushing booster pump 14 to open, and flushes the water in the water storage tank 11 into the toilet cavity 2. When the toilet lid sensor 8 detects that the toilet lid 4 is closed but the human body sensor 7 does not detect that a human body is approaching, the main control chip controls the flushing solenoid valve 6 and the flushing booster pump 14 to open at a preset cycle for flushing.

[0043] Among them, after the water in the water tank 11 is flushed into the toilet cavity 2, the main control chip will open the water inlet solenoid valve 13 to replenish tap water into the water tank 11.

[0044] In this application, in order to achieve the control of each impulse, refer to Figure 5As shown, a first water level sensor 15, a second water level sensor 16 and a third water level sensor 17 are arranged in the water tank 11. The first water level sensor 15, the second water level sensor 16 and the third water level sensor 17 are distributed in upper and lower positions. The first water level sensor 15 is arranged at the top end of the water tank 11, and the third water level sensor 17 is arranged at the bottom end of the water tank 11.

[0045] The water volume between the first water level sensor 15 and the second water level sensor 16 is a small flushing water volume, and the water volume between the first water level sensor 15 and the third water level sensor 17 is a large flushing water volume. When the main control chip controls the flushing solenoid valve 6 to open for flushing, the water level in the water tank 11 is controlled between the first water level sensor 15 and the second water level sensor 16.

[0046] That is, when the toilet lid sensor 8 detects that the toilet lid 4 is closed and the human body sensor 7 detects that a human body is approaching, the main control chip controls the flushing solenoid valve 6 and the flushing booster pump 14 to start flushing, and when the toilet lid sensor 8 detects that the toilet lid 4 is closed but the human body sensor 7 does not detect that a human body is approaching, the main control chip controls the flushing solenoid valve 6 and the flushing booster pump 14 to start flushing at a preset cycle, both with a small flushing water volume, to achieve the effect of saving water resources. However, a large flushing water volume can be achieved through the flush button on the remote control, and the above settings can effectively improve the application of functional scenarios.

[0047] Embodiment 3

[0048] Based on the second embodiment, refer to Figure 6 As shown, the water tank 11 is provided with an adjusting component 18 for adjusting the upper and lower heights of the second water level sensor 16. The adjusting component 18 can adjust the upper and lower heights of the second water level sensor 16, thereby achieving the adjustment of a small flushing water volume.

[0049] The adjustment component 18 includes an electric cable reel 181, an adjustment rope 182 and a tension spring 183. A mounting seat 184 is slidably installed on the side wall of the water tank 11 in the vertical direction. The second water level sensor 16 is fixed on the mounting seat 184. The electric cable reel 181 is arranged on the top of the water tank 11. A wire opening 185 is opened on the top of the water tank 11. One end of the adjustment rope 182 is connected to the mounting seat 184, and the other end of the adjustment rope 182 passes through the wire opening 185 to be wound around the electric cable reel 181. One end of the tension spring 183 is connected to the mounting seat 184, and the other end of the tension spring 183 is connected to the bottom of the inner wall of the water tank 11. The electric cable reel 181 is electrically connected to the main control chip.

[0050] A sealing rubber layer is installed in the wire opening 185 , and the adjustment rope 182 passes through the sealing rubber layer. The sealing rubber layer can prevent the water in the water storage tank 11 from overflowing from the wire opening 185 to a certain extent.

[0051] It is worth noting that the main control chip is connected with an adjustment button. In one embodiment, the adjustment button is arranged on the toilet body 1, and in another embodiment, the adjustment button is arranged on the remote control. The adjustment button is used to control the electric reel 181 to rotate forward or reverse, thereby adjusting the position of the second water level sensor 16 in the water tank 11.

[0052] When the smart toilet is used frequently, the second water level sensor 16 can increase the small flushing water volume, which can take away more odor in the toilet cavity 2, and when there is dirt in the smart toilet, the dirt in the toilet cavity 2 can also be discharged.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
