Technical Field
[0001] This utility model relates to the field of toilet seat technology, specifically a functional water-filled toilet seat. Background Technology
[0002] In daily life, toilet seat cushions are bathroom products that come into direct contact with the human body, and their comfort and hygiene have always been the focus of users' attention. To ensure hygiene, most users choose to put toilet seat cushions on the toilet seat, but the existing toilet seat cushion designs are difficult to meet diverse usage needs. Currently common toilet seat covers have a simple structure, mostly made of a single layer of fabric or silicone, and have a single function. They are affected by seasonal temperature. In winter, toilet seat covers will feel cold to the touch due to the low temperature, while in summer, they will easily accumulate heat due to their lack of breathability, resulting in stuffiness and discomfort in the contact area. Although some users will change the toilet seat cover material according to the season (such as using a plush cover in winter and an ice silk cover in summer), frequent changes not only increase the storage and cleaning costs, but also cannot flexibly adjust the temperature. Plush covers will become stuffy when the room temperature rises suddenly, and ice silk covers will still retain a cool feeling in low-temperature environments, making it difficult to achieve true temperature adaptation. In addition, for users who need to sit for long periods of time (such as the elderly, pregnant women, or people with constipation), existing toilet seat covers lack support and massage design. When sitting for a long time, the groin and buttocks are subjected to continuous pressure, which can easily lead to poor local blood circulation, causing discomfort such as numbness and soreness, and may even aggravate leg muscle fatigue. The flat structure of ordinary toilet seat covers cannot distribute pressure, nor can they relieve muscle tension through active intervention, further reducing the user experience. Existing toilet seat covers have significant shortcomings in terms of temperature regulation, pressure distribution, and muscle relaxation, failing to meet the needs of different seasons and the comfort of users who sit for long periods. Water-filled toilet seat covers also have poor sealing performance, failing to provide multiple seals for the water filling structure, resulting in water leakage that affects the normal use of the toilet seat cover. Therefore, there is an urgent need for a functional water-filled toilet seat cover that can solve the problems of temperature discomfort and fatigue from prolonged sitting through water filling temperature regulation, pressure distribution, and massage design, thereby improving the comfort and practicality of toilet use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0016] Please refer to Figure 1-5 As shown, this utility model provides a functional water-filled toilet seat, including a seat 1. The seat 1 has an inner cavity 2 for holding water. One end of the cavity 2 is fitted with a water inlet 3. One end of the water inlet 3 is screwed with a sealing cap 4. A sealing element for preventing leakage is installed between the sealing cap 4 and the water inlet 3.
[0017] It should be added that the seat cushion 1 is made of natural rubber material. Hot or cold water can be injected into the movable cavity 2 inside the seat cushion 1 through the water inlet 3 as needed. Then tighten the sealing cap 4 and place the seat cushion 1 on the toilet seat. When you sit on it, the water inside the seat cushion can flow with the body's sitting posture. It can be used all year round, improving the user's comfort when using the seat cushion 1 on the toilet.
[0018] Specifically, the sealing element includes a sealing post 5 integrally formed with the inner side of the sealing cap 4, a plurality of evenly arranged sealing rings 6 fixedly connected to the outer side of the sealing post 5, a plurality of evenly arranged sealing grooves 7 opened on the inner side of the water inlet 3, a sealing ring 11 fixedly connected to one side of the sealing cap 4, a gasket 12 laid on one end of the water inlet 3, a sealing part 13 extending from one side of the sealing ring 11, and the sealing part 13 embedded in one side of the gasket 12.
[0019] In this process, the sealing post 5 on one side of the sealing cap 4 is inserted into the water inlet 3. The sealing cap 4 drives the sealing post 5 to be screwed and fixed to the water inlet seat. The sealing ring 11 and the gasket 12 fit together. At the same time, the sealing part 13 on one side of the sealing ring 11 is embedded in one side of the gasket 12. The sealing post 5 blocks and seals the water. Multiple sealing rings 6 on the outside of the sealing post 5 are embedded in the sealing groove 7 on the inner side wall of the water inlet 3 for double sealing, preventing water from overflowing and increasing the sealing effect between the sealing post 5 and the water inlet 3.
[0020] More specifically, multiple massage balls 8 are fixedly connected to the top of the seat cushion 1 and near both sides, and a deformation cavity 9 is opened on the inner side of the massage ball 8. An elastic frame 10 is fixedly connected to the inside of the movable cavity 2 and near both sides.
[0021] In addition, multiple massage balls 8 can relieve fatigue from prolonged sitting and provide a certain patting effect on the thigh muscles. The deformation cavity 9 inside the massage ball 8 can increase the degree of deformation of the massage ball 8, and the elastic frame 10 inside the movable cavity 2 can support the seat cushion 1 and increase the pressure resistance of the seat cushion 1.
[0022] Furthermore, anti-slip mats 14 are laid on both sides of the bottom of the seat cushion 1 and near the front end. Multiple water guide grooves 15 are evenly arranged on the bottom of the anti-slip mats 14. The three anti-slip mats 14 can be located on both sides and the front end of the toilet respectively. The anti-slip mats 14 are made of rubber and can fit tightly against the toilet surface to prevent the seat cushion 1 from sliding. The multiple water guide grooves 15 on the bottom of the anti-slip mats 14 can facilitate the drainage of water stains and prevent water stains from affecting the stability of the seat cushion 1.
[0023] Working principle: First, hot or cold water is injected into the movable cavity 2 inside the seat cushion 1 through the water inlet 3 as needed, so that the sealing post 5 on one side of the sealing cap 4 is inserted into the water inlet 3. Then, the sealing cap 4 is screwed and fixed to the water inlet 3. At this time, the sealing cap 4 drives the sealing post 5 to be screwed and fixed to the water inlet seat. Multiple sealing rings 6 on the outside of the sealing post 5 are embedded in the sealing groove 7 on the inner side wall of the water inlet 3. At the same time, the sealing ring 11 is in contact with the pad ring 12, and the sealing part 13 on one side of the sealing ring 11 is embedded in one side of the pad ring 12. Then, the seat cushion 1 is placed on the toilet. Then, the massage ball 8 supports and massages the user's thigh muscles, and the elastic frame 10 supports the seat cushion 1.
[0024] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
