Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1 and 6 In this embodiment, a filter structure built into the toilet lid is used to fully filter the water body and reduce impurities in the water body;

[0030] Specifically, it includes a toilet seat 1, a cushion 2 and a cover body 3, and is characterized in that: the cushion 2 is installed on the toilet seat 1 through a hinge shaft, and the cover body 3 is hinged on the cushion 2 through a hinge shaft; an installation cavity 5 is opened inside the cushion 2, and a water spraying device 6 is arranged on the inner side of the cushion 2; a filter component 4 is arranged inside the installation cavity 5.

[0031] In actual settings, a filter assembly 4 is arranged inside the toilet seat 3, the water is filtered through the filter assembly 4, and then the filtered water is transmitted to the inside of the water spraying device 6 and sprayed out through the water spraying device 6 to clean the user such as the back.

[0032] See also Figure 2-4In order to clean the water, the filter assembly 4 in this embodiment includes at least two water injection cylinders 401, and at least the two water injection cylinders 401 are arranged inside the installation cavity 5 in the X-axis direction. The left ends of at least the two water injection cylinders 401 penetrate and extend to the outside of the seat cushion 2. Filter elements 402 are arranged inside the at least two water injection cylinders 401. At least the two water injection cylinders 401 are connected by a connecting pipe 403. A water inlet pipe 404 connected to the lower water injection cylinder 401 is installed on the outside of the seat cushion 2; the upper water injection cylinder 401 is connected to the water spraying device 6 to transport the filtered water to the inside of the water spraying device 6.

[0033] During actual use, water from the outside is transported to the interior of the lower water injection cylinder 401 through the water inlet pipe 404, and is filtered by the filter element 402 inside the lower water injection cylinder 401. The water after preliminary filtration is transported to the interior of the upper water injection cylinder 401 through the connecting pipe 403, and is further filtered by the filter element 402 inside the upper water injection cylinder 401. Finally, the filtered water is transported to the interior of the water spraying device 6 and sprayed out through the water spraying device 6.

[0034] Preferably, in order to facilitate the cleaning of the filter element 402, at least two water injection cylinders 401 in this embodiment are shaped like cylinders with a hollow interior and a missing left side. In addition, a sealing plug 405 is interference fit inside the water injection cylinder 401, and the filter element 402 is assembled at one end of the sealing plug 405 located inside the water injection cylinder 401.

[0035] During actual use, the filter element 402 can be taken out from the water injection cylinder 401 by pulling out the sealing plug 405 from the inside of the water injection cylinder 401. In addition, in this embodiment, the sealing plug 405 is preferably an elastic plastic plug, so that after the sealing plug 405 is inserted into the water injection cylinder 401, it can fit tightly with the inner wall of the water injection cylinder 401, thereby ensuring the sealing effect between the two.

[0036] In actual settings, the shape of the water filling barrel 401 is designed to be a cylinder with a hollow interior and a missing left side, so that the user can easily remove the filter element 402 without the need for additional tools, thereby simplifying the cleaning and maintenance process. In addition, a sealing plug 405 is interference fit inside the water filling barrel 401, so that the user only needs to pull out the sealing plug 405 to take out the filter element 402, thereby facilitating the cleaning of the filter element 402. Moreover, the sealing plug 405 is made of elastic plastic material, and can fit tightly against the inner wall after being inserted into the water filling barrel 401, thereby ensuring a sealing effect and preventing water from flowing around the filter element 402 and causing pollution.

[0037] Furthermore, in order to facilitate the transportation of water to the interior of the lower filter element 402 , corresponding to the water inlet pipe 404 , a connection port for communicating with the water inlet pipe 404 is opened inside the lower filter element 402 .

[0038] In actual settings, a connection port is opened inside the lower filter element 402 for connecting with the water inlet pipe 404, so that water can be directly transported from the water inlet pipe 404 to the inside of the lower filter element 402, ensuring that the water fully contacts the filter element 402 and improving the filtration efficiency.

[0039] Furthermore, in order to ensure that the water input from the lower water injection cylinder 401 into the upper water injection cylinder 401 can effectively enter the upper filter element 402, the corresponding connecting pipe 403 in this embodiment is provided with a separating ring 406 inside the upper water injection cylinder 401, and the separating ring 406 is sleeved on the outside of the filter element 402, and the separating ring 406, the water injection cylinder 401, the filter element 402 and the sealing plug 405 cooperate with each other to form a water injection cavity; and the output end of the connecting pipe 403 is located inside the water injection cavity.

[0040] In actual settings, a water injection cavity is formed by cooperating the separating ring 406, the water injection cylinder 401, the filter element 402 and the sealing plug 405 to ensure that the water transported to the upper water injection cylinder 401 enters the inner side of the filter element 402 from the outer side of the filter element 402, and the water can be further filtered in this process.

[0041] See also Figure 3 and 4 In order to improve the sealing effect between the sealing plug 405 and the water injection cylinder 401, at least two sealing plugs 405 in this embodiment are equipped with the same connecting plate 407 on the left side. The connecting plate 407 is attached to the left side of the seat cushion 2, and a fastener 408 with one end threadedly connected to the seat cushion 2 is connected through the inside of the connecting plate 407.

[0042] In actual use, the sealing plug 405 can be pushed into the water injection cylinder 401 by tightening the fastener 408, while making the connecting plate 407 fit with the seat cushion 2. Conversely, the sealing plug 405 can be pulled out from the water injection cylinder 401 by loosening the fastener 408.

[0043] In summary, the filtering structure built into the toilet cover transports the water from the outside to the inside of the lower water injection cylinder 401 through the water inlet pipe 404, and is filtered by the filter element 402 inside the lower water injection cylinder 401. The water after preliminary filtration is transported to the inside of the upper water injection cylinder 401 through the connecting pipe 403, and is further filtered by the filter element 402 inside the upper water injection cylinder 401. The cooperation of the two filter elements 402 can effectively filter the water, ensure the cleanliness of the water sprayed from the water spraying device 6, and by connecting the two cylindrical The water filling cylinder 401 is arranged inside the seat cushion 2 along the X-axis direction, which reasonably utilizes the cavity inside the seat cushion 2 and improves the filtering effect on the water body. By pulling out the sealing plug 405 from the inside of the water filling cylinder 401, the filter element 402 can be taken out from the inside of the water filling cylinder 401. In addition, the sealing plug 405 is preferably an elastic plastic plug, so that after the sealing plug 405 is inserted into the inside of the water filling cylinder 401, it can fit tightly with the inner wall of the water filling cylinder 401, thereby ensuring the sealing effect between the two, and also facilitating the cleaning and maintenance of the filter screen in the water filling cylinder 401.
