[0002] With the continuous improvement of people's hygiene requirements, the cleaning and disinfection of toilets have become an essential part of daily life. The traditional toilet cleaning method usually relies on manually adding disinfectant or using disinfection cleaning agents, which is cumbersome and inconvenient to operate. In the prior art, some toilets are already equipped with automatic flushing devices, but there are still many deficiencies in the automatic disinfection function, and it cannot effectively achieve automation and self-cleaning. Users still need to frequently manually operate to add disinfectant, which is time-consuming and laborious.

[0003] In the prior art, the design of the automatic disinfection system is relatively complex, and it often needs to be externally connected to a power source or other power sources, resulting in increased costs, inconvenient maintenance, and problems with operation stability. At the same time, the control of the addition and release of disinfectant is not precise enough, which is likely to cause waste or insufficient use of disinfectant and cannot achieve the ideal disinfection effect. Traditional designs often fail to make full use of the natural characteristics of gravity and buoyancy, resulting in cumbersome device operation and high energy consumption. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an automatic disinfection and self-cleaning mechanism for a toilet, which can simplify the structure, reduce the cost, and improve the convenience and reliability of use while ensuring the disinfection effect.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An automatic disinfection and self-cleaning mechanism for a toilet, comprising a support assembly installed at the bottom of a toilet water tank. A liquid storage tank is slidably connected above the support assembly, and the liquid storage tank is used for storing disinfectant.

[0007] A tank cover is connected to the top tank opening of the liquid storage tank, and a communicating pipe is fixedly connected to the top of the tank cover, and the communicating pipe and the tank cover communicate with each other.

[0008] A guiding mechanism is fixedly connected to the outside of the liquid storage tank. The guiding mechanism includes a limiting seat, and an air ring is clamped outside the limiting seat.

[0009] A liquid discharge hole is formed through the bottom of the liquid storage tank, and a reset mechanism is arranged at the inner bottom of the liquid storage tank. When the liquid storage tank floats, the reset mechanism seals the liquid discharge hole.

[0010] The support assembly includes a base, a cross bar is fixedly connected to the middle of the base, a trigger post corresponding to the liquid discharge hole is arranged on the upper end surface of the cross bar, and when the bottom of the liquid storage tank contacts the trigger post, the trigger post dredges the base.

[0011] Furthermore, cushion blocks are symmetrically and fixedly connected to the upper end surface of the cross bar;

[0012] Flow guiding grooves are equidistantly arranged around the outer side of the trigger post along its central axis.

[0013] Furthermore, guiding posts are symmetrically and fixedly connected to the upper end surface of the base, guiding holes corresponding to the guiding posts are penetrated through the upper end surface of the limiting seat, and the guiding posts penetrate through the guiding holes.

[0014] Furthermore, a retaining ring is fixedly connected to the outer side of the top of the limiting seat, and a clamping groove is arranged on the outer side of the limiting seat, and the air ring is clamped into the clamping groove.

[0015] Furthermore, connecting seats are symmetrically and fixedly connected to the bottom of the liquid storage tank, the reset mechanism includes a screw installed on the connecting seat, and a spring is sleeved on the screw;

[0016] And an extrusion plate is slidably connected to the screw, limiting holes are symmetrically penetrated through the upper end surface of the extrusion plate, and the screw passes through the limiting holes.

[0017] Furthermore, a sealing plug is fixedly connected to the bottom of the extrusion plate, and the sealing plug corresponds to the liquid discharge hole.

[0018] Furthermore, fixing holes are symmetrically penetrated through the upper end surface of the base.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] Firstly, the support assembly in the present utility model includes a base and a cross bar. By fixedly installing the base on the water tank, the stability of the entire mechanism is ensured. The cross bar not only provides support for the liquid storage tank, but also the trigger post on its upper end surface can effectively open the liquid discharge hole when the liquid storage tank moves downward, thereby releasing the disinfectant. This design avoids the cumbersome operation of manually adding disinfectant in the traditional way, realizes automatic operation, and greatly facilitates the users.

[0021] Secondly, the design of the liquid storage tank enables the disinfectant to be automatically added to the water tank under the action of gravity and buoyancy. When the water in the water tank is drained, the liquid storage tank moves downward due to gravity, triggering the column to open the liquid discharge hole, and the disinfectant flows smoothly into the water tank; when the water tank is filled with water, the air ring generates buoyancy to make the liquid storage tank rise, and the spring and the sealing plug in the reset mechanism seal the liquid discharge hole to ensure that the disinfectant is not released excessively. In this way, the disinfectant can effectively disinfect the inner wall of the toilet during each flushing, ensuring both the cleaning effect and avoiding the waste of disinfectant.

[0022] Thirdly, the guiding mechanism includes a limit seat and an air ring. The guiding column is matched with the guiding hole of the limit seat to ensure that the liquid storage tank remains stable during the up and down movement, avoiding uneven release of the disinfectant caused by deviation. The clamping groove and the retaining ring on the limit seat ensure that the air ring does not fall off during use, providing reliable buoyancy support and making the addition process of the disinfectant more stable and accurate.

[0023] Finally, the pressing plate and the sealing plug in the reset mechanism seal the liquid discharge hole under the action of the spring, avoiding the leakage of the disinfectant and ensuring that the disinfectant in the liquid storage tank does not flow out accidentally in the non-working state, thus ensuring the use efficiency and effect of the disinfectant.

[0044] Refer to Figure 4-5 , on the upper end face of the cross bar 13, cushion blocks 131 are symmetrically and fixedly connected; the cushion blocks 131 provide additional support and stability to ensure that the trigger post 14 is not easily offset during use; on the outer side of the trigger post 14, flow guiding grooves 141 are equidistantly arranged around its central axis; the flow guiding grooves 141 contribute to the smooth outflow of the disinfectant solution and avoid blockage.

[0045] Refer to Figure 4-6 , on the upper end face of the base 11, guiding posts 12 are symmetrically and fixedly connected, and through holes 411 corresponding to the guiding posts 12 are penetrated through the upper end face of the limit seat 41, and the guiding posts 12 penetrate through the through holes 411; the guiding posts 12 ensure that the limit seat 41 remains vertically stable when moving up and down and avoid offset affecting the normal release of the disinfectant solution.

[0050] The working principle of the present utility model is as follows:

[0051] When in use, store the disinfectant solution in the liquid storage tank 2;

[0052] When flushing the toilet, when the water in the water tank is drained, under the action of the gravity exerted on the liquid storage tank 2 itself, the liquid storage tank 2 will move downward. As the height of the liquid storage tank 2 gradually decreases, the trigger post 14 will extend into the liquid discharge hole 21 and contact the bottom of the sealing plug 532. At the same time, the sealing plug 532 will be separated from the liquid discharge hole 21, so that the disinfectant liquid in the liquid storage tank 2 can flow out from the liquid discharge hole 21 into the water tank. In this way, when the toilet is flushed next time, the water mixed with the disinfectant liquid in the water tank can disinfect and flush the inner wall of the toilet during the flushing process;

[0053] When the water tank is filling with water, as the water in the water tank increases, the buoyancy force exerted on the air ring 42 will be greater than the gravity exerted on the entire liquid storage tank 2. Then, under the action of the buoyancy force, the bottom of the liquid storage tank 2 will be separated from the trigger post 14. At this time, under the extrusion of the spring 52, the extrusion plate 53 at its bottom will move closer to the liquid discharge hole 21, and then the sealing plug 532 will seal the liquid discharge hole 21.

[0054] In this way, the cooperation of gravity and buoyancy can be utilized to add the disinfectant liquid in the liquid storage tank 2 into the toilet water tank, thereby facilitating the disinfection operation of the toilet more conveniently.

[0055] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
