Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to an infrared sensor switch for toilets. Background Art

[0002] The toilet infrared sensor switch works on the principle of infrared reflection. When a person enters the sensing area, the sensor detects changes in the infrared spectrum of the human body, triggering the switch to control the flushing system. It uses a combination of electromechanical methods to achieve automatic flushing and control the amount of flushing. It is easy to use and has powerful sensing functions.

[0003] During the use of the toilet infrared sensor switch, the shell is locked in the ceramic hole of the ceramic toilet using a locking nut, and the flushing operation of the smart toilet is triggered by infrared sensing.

[0004] During the use of the existing toilet infrared sensor switch, when the infrared sensor switch is replaced later, it is inconvenient for the user to remove the infrared sensor from the housing because the infrared sensor is installed inside the housing by bolts or other tools, resulting in cumbersome replacement and affecting the practicality of the device.

[0033] Specifically, the bottom end of the pressing rod 505 is set as a slope, and the lower end of the pressing rod 505 abuts against the slope slot 5031. When the pressing rod 505 moves downward, the distance that the card block 503 moves backward is longer than the depth of the installation slot 501, so as to ensure that the card block 503 can be separated from the installation slot 501.

[0034] Furthermore, through the installation component 5, when installing, by pressing the infrared sensor body 1, the outer surface of the infrared sensor body 1 drives the abutment plate 509 downward to move downward in the T-slot 506. At this time, the telescopic spring 508 is compressed. When the installation slot 501 and the installation slot 502 are at the same horizontal line, the two ends of the spring 504 are fixedly connected to the inner wall of the installation slot 502 and the outer surface of the block 503 respectively. The spring 504 pushes the block 503 forward to move forward, so that the block 503 is engaged with the installation slot 501. At this time, the infrared sensor body 1 is plugged into the housing 2. When disassembling, By pressing the button, the pressing rod 505 is driven to move downward in the pressing groove, and the pressing rod 505 is abutted against the inclined slot 5031. The pressing rod 505 moves downward, driving the card block 503 to move backward until the card block 503 is separated from the installation card slot 501. The elastic potential energy of the telescopic spring 508 is then used to pop out the infrared sensor body 1. The telescopic spring 508 is used to drive the abutment plate 509 to move upward, and the abutment plate 509 drives the infrared sensor body 1 to move upward. There is no need to manually use tools to pop out the infrared sensor body 1 from the housing 2. The operation is simple, which improves the practicality of the device.

[0035] Example 2

[0038] Specifically, the sealing plate 403 is inserted into the interior of the sealing groove 401, and the width of the sealing plate 403 is smaller than the width of the sealing groove 401. The butterfly spring 402 is arranged between the sealing plate 403 and the sealing groove 401. The sealing gasket 404 is made of soft rubber, and the width of the sealing gasket 404 is greater than the width of the sealing groove 401. The upper surface of the pressing rod 505 is provided with a mounting cover to prevent the pressing rod 505 from separating from the outer shell 2. A button is provided at one end of the pressing rod 505 close to the mounting cover, and a pressing groove for moving the button is provided inside the outer shell 2.

[0039] Furthermore, through the sealing assembly 4, when the user turns the locking nut 3, the outer shell 2 is fitted with the outer surface of the ceramic toilet. By utilizing the elasticity of the butterfly spring 402, the outer wall of the ceramic toilet squeezes the sealing gasket 404 and the sealing plate 403, and through the butterfly spring 402, the sealing plate 403 and the sealing gasket 404 tightly connect the outer shell 2 and the outer surface of the ceramic toilet, avoiding the formation of gaps at the connection between the outer shell 2 and the ceramic toilet due to long-term use, thereby improving the sealing of the toilet infrared sensor switch.

[0040] When the fixing plate 501 is in the same horizontal line as the fixing slot 502, the two ends of the spring 504 are fixedly connected to the inner wall of the fixing slot 502 and the outer surface of the card block 503, and the spring 504 pushes the card block 503 forward so that the card block 503 is engaged with the fixing slot 501.

The shell 2 is then placed in the ceramic hole opened on the outer surface of the ceramic toilet and is locked and installed using the locking nut 3. When the user turns the locking nut 3, the shell 2 is fitted with the outer surface of the ceramic toilet. The elasticity of the butterfly spring 402 is used to squeeze the sealing gasket 404 and the sealing plate 403 on the outer wall of the ceramic toilet, and the butterfly spring 402 is used to make the sealing plate 403 and the sealing gasket 404 tightly connect the shell 2 to the outer surface of the ceramic toilet. Compared with traditional technology, this device can avoid the formation of gaps at the connection between the shell 2 and the ceramic toilet due to long-term use through the interaction between the sealing gasket 404 and the butterfly spring 402, thereby improving the sealing of the toilet infrared sensing switch.
