Description

Technical field:

[0001] The utility model belongs to the technical field of toilets, in particular to a toilet cover closing and flushing device. Background technology:

[0002] The toilet is a commonly used toilet tool in family hotels, and is an important part of the sitting toilet. When the flush toilet is in use, liquid may splash out during the flushing process, and bacteria and pathogens in the toilet may splash out from the toilet and spread in the bathroom. Therefore, in order to ensure hygiene and cleanliness, many people cover the toilet lid before flushing. This increases the operation steps during flushing and causes certain inconveniences. Therefore, a toilet lid closing flushing device is proposed to achieve the simultaneous start of flushing when the toilet lid is closed. Summary of the invention:

[0003] The utility model aims to provide a toilet lid closing and flushing device, which can realize the flushing started when the toilet lid is closed.

[0004] The utility model is implemented as follows: a toilet lid closing and flushing device comprises a toilet back seat and a flushing assembly, wherein the toilet back seat is provided with a seat cover rotating shaft mounting hole, the seat cover rotating shaft is penetrated in the seat cover rotating shaft mounting hole, a trigger key is provided on the seat cover rotating shaft, the trigger key is located inside the toilet back seat, a flushing sensor is provided inside the toilet back seat, when the lid is closed, the trigger key rotates with the seat cover rotating shaft, triggering the flushing sensor to drive the flushing assembly to flush.

[0005] In the above-mentioned toilet lid closing and flushing device, the flushing sensor is a micro switch, and the micro switch includes an action reed. When the lid is closed, the trigger key rotates with the seat cover shaft and acts on the action reed.

[0006] In the above-mentioned toilet lid closing and flushing device, the flushing sensor can also be a Hall sensor, and the trigger key includes a magnet that senses the Hall sensor.

[0007] In the above-mentioned toilet lid flushing device, more than two fixing columns are arranged on the inner wall of the toilet back seat, and the flush sensor is provided with fixing holes corresponding to the positions and numbers of the fixing columns. The flush sensor is passed through the fixing holes on the fixing columns, and the fixing columns and the fixing holes fix the flush sensor to the toilet back seat.

[0008] In the above-mentioned toilet lid closing and flushing device, a first fixing seat and a second fixing seat are arranged on the inner wall of the toilet rear seat, and the outer ends of the first fixing seat and the second fixing seat are provided with barbs. The flush sensor is installed between the first fixing seat and the second fixing seat, and the barbs are buckled on the upper surface of the flush sensor. A limiting plate is also provided on the inner wall of the toilet rear seat, which abuts against the lower end of the flush sensor. The electronic component is further fixed on the inner wall of the toilet rear seat by the first fixing seat, the second fixing seat and the limiting plate to prevent the electronic component from deflecting.

[0009] In the above-mentioned toilet lid closing and flushing device, a sealing ring is arranged between the seat cover rotating shaft and the seat cover rotating shaft mounting hole to prevent water from seeping into the back seat of the toilet during use and damaging electronic components.

[0010] In the above-mentioned toilet lid closing and flushing device, the part of the seat cover shaft located outside the toilet back seat is the seat cover connecting part, and the inner end surface of the seat cover connecting part is provided with a fan-shaped recess, and a limit block is provided on the side wall adjacent to the fan-shaped recess on the toilet back seat. The limit block extends into the fan-shaped recess to limit the rotation angle of the seat cover, thereby preventing the seat cover shaft from rotating too much during use, resulting in separation from the action range of the trigger key and the action reed, making the toilet lid closing and flushing device invalid, and at the same time ensuring that the trigger key will not interfere with the action reed when the toilet lid is opened.

[0011] The outstanding advantages of the utility model compared with the prior art are:

[0012] 1. The utility model fixes the electronic component and the toilet back seat through the first fixing seat, the second fixing seat and the fixing column, and realizes the connection between the seat cover rotating shaft and the toilet back seat by inserting the seat cover rotating shaft into the seat cover rotating shaft installation hole. No fasteners are required for assembly, and no tools are required for disassembly and assembly, which is convenient and quick;

[0013] 2. When the lid is closed, the trigger key rotates with the seat cover shaft, and the trigger key presses the action spring, triggering the flush sensor to drive the flush assembly to flush, so as to realize the function of closing the toilet lid and starting the flush at the same time. The lid closing and flushing are combined into one, which saves one operation step and avoids the splashing of liquid during flushing, thus ensuring the cleanliness of the toilet.
