[0012] By adopting the above technical solution, the beneficial effects are as follows: 1. The control mechanism is used to control the liquid outlet of the liquid outlet hole in the storage cavity, the water storage amount in the water tank is used as the pressure change condition, at this time, the different pressures formed by the water storage amount in the water tank can make the different magnetism of the electromagnet, the liquid outlet control of the liquid outlet hole is realized, and the disinfectant liquid forms the corresponding liquid outlet operation with the change of the water tank drainage, so that good disinfection effect is realized, the practicality is strong, and the structure is simple.

[0013] 2. By setting the control mechanism to include a diaphragm that is directly in contact with the water in the toilet tank and located in the control chamber, a fixing ring located below and connected to the diaphragm, a micro-touch switch located below the fixing ring, and a control circuit electrically connected to the micro-touch switch, and the control circuit includes an electromagnet, a power supply, and a controller that are electrically connected in sequence. The electromagnet produces different magnetic properties due to changes in the amount of current it carries.

A return spring is provided between the permanent magnet and the electromagnet. With the above structure, when the electromagnet undergoes a change in magnetism, the permanent magnet will move closer to or away from the electromagnet. At this time, the connecting rod structure connected to the permanent magnet will cooperate with the cover plate structure to form a corresponding reciprocating motion, thereby realizing the control of liquid discharge. It is highly practical and has a simple structure.

[0015] 4. The reflective structure, combined with the ultraviolet lamp, creates a sterilization effect on the upper and lower surfaces of the toilet seat. It employs a main board structure made of thermoplastic resin material.

The arc-shaped structure A is formed of a first resin material and has a convex interface formed by the connecting surfaces of the arc-shaped structure A and the arc-shaped structure B, as well as a first vertex located on the convex interface. The arc-shaped structure B is formed of a second resin material including photosensitive resin and has an outer surface spaced from the convex interface of the arc-shaped structure A, as well as a second vertex located on the outer surface. This achieves a good reflective effect, facilitating sterilization of the upper surface of the toilet seat in conjunction with the ultraviolet lamp. Furthermore, the reflective structure is positioned along the periphery of the toilet seat, thus not affecting its normal use. It is highly practical and has a simple structure.

[0016] A control method applicable to the above-mentioned toilet sterilizer includes the following steps: S1. When the toilet tank is at the normal water level, the diaphragm is under the greatest force. The fixed ring connected below the diaphragm continues to exert force on the micro-touch switch. At this time, the control circuit electrically connected to the micro-touch switch is energized, the electromagnet is energized, and it exerts a continuous force on the permanent magnet. The cover is in a sealed state.

[0017] S2. During the flushing stage, as the water level decreases, the force on the diaphragm decreases. At this time, the micro-touch switch loses its force, the control circuit is broken, the electromagnet is de-energized, and the permanent magnet is reset under the action of the reset spring. At this time, the cover is in the open state, and the disinfectant in the storage cavity flows out.

[0018] S3. When the water level in the storage tank rises, the force on the diaphragm increases as the water level in the tank continues to rise. At this time, the micro-touch switch is gradually activated and the force increases. The control circuit is energized, the electromagnet is energized, and a continuous force is exerted on the permanent magnet. The cover is in a liquid-sealing state.

[0019] S4. Complete the above operations.

[0020] By adopting the above technical solution, the beneficial effects are achieved by using the water volume in the toilet tank as a control condition.

In combination with the linkage structure and the reset spring, the effect of liquid discharge or reset is achieved. The structure is simple, the triggering condition is simple, it is highly practical, and it is easy to operate. Attached Figure Description

[0025] Reference Figs. 1 to 3 The present invention provides a further description of an embodiment of a toilet sterilizer and disinfection device and its control method.

[0026] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0027] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0028] A toilet sterilizer includes a disinfectant control unit installed in the toilet tank and an ultraviolet light irradiation unit installed on the toilet seat. The disinfectant control unit includes a mounting bracket 1 placed inside the toilet tank and a disinfectant container 2 installed on the mounting bracket 1. The disinfectant container 2 includes a cylinder 20 and a bottom cover 21. The bottom cover 21 needs to be opened for use. The cylinder 20 includes a storage chamber 201 and a control chamber 202 located above the storage chamber 201. The storage chamber 201 has a liquid outlet 203. The control chamber 202 has a control mechanism for controlling the liquid outlet 203. By using the control mechanism to control the liquid outlet 203 in the storage chamber 201, the water volume in the tank is used as a condition for pressure change. At this time, the different pressures formed by the water volume in the tank cause different magnetic fields of the electromagnet 330, thereby realizing the liquid outlet control of the liquid outlet 203. Moreover, the disinfectant liquid is dispensed according to the water volume changes, thus achieving a good disinfection effect. It is practical and has a simple structure.

[0029] The present invention is further configured such that the control mechanism includes a diaphragm 30 disposed within the control chamber 202 and in direct contact with the water in the toilet tank, a fixing ring 31 disposed below and connected to the diaphragm 30, a micro-touch switch 32 disposed below the fixing ring 31, and a control circuit 33 electrically connected to the micro-touch switch 32. The control circuit 33 includes an electromagnet 330, a power supply 331, and a controller 332 connected in sequence. By configuring the control mechanism to include a diaphragm 30 disposed within the control chamber 202 and in direct contact with the water in the toilet tank, a fixing ring 31 disposed below and connected to the diaphragm 30, a micro-touch switch 32 disposed below the fixing ring 31, and a control circuit 33 electrically connected to the micro-touch switch 32, the present invention provides a more comprehensive control mechanism. The device includes a fixing ring 31 located below and connected to the tympanic membrane 30, a micro-touch switch 32 located below the fixing ring 31, and a control circuit 33 electrically connected to the micro-touch switch 32. The control circuit 33 includes an electromagnet 330, a power supply 331, and a controller 332 connected in sequence. The electromagnet 330 produces different magnetic properties due to changes in the amount of current flowing through it. Using the electromagnet 330 as the main control means can amplify the control range and improve its practicality. Furthermore, the structure of the tympanic membrane 30 can increase the pressure sensing effect and amplify the effect of current changes.

A return spring 38 is provided between the permanent magnet 36 and the electromagnet 330. With the above structure, when the electromagnet 330 undergoes a magnetic change, the permanent magnet 36 will move closer to or away from the electromagnet 330. At this time, the connecting rod structure 35 connected to the permanent magnet 36 will cooperate with the cover plate 34 structure to form a corresponding reciprocating motion, thereby realizing the control of liquid discharge. It is highly practical and has a simple structure.

[0031] The present invention is further configured such that a sliding structure is provided between the cover plate 34 and the storage cavity 201.

The buffer spring 41 is disposed on one side of the sliding direction when the cover plate 34 opens the liquid outlet hole 203. With the above structure, when the cover plate 34 is pushed, a reverse force can be generated by the buffer spring 41, thereby ensuring the stability of the liquid outlet and avoiding a large amount of disinfectant flowing out, which would affect the subsequent normal use. The structure is simple and highly practical.

[0032] The present invention is further configured such that the ultraviolet light irradiation part includes a mounting ring 50 disposed below the toilet seat, an ultraviolet lamp tube 51 disposed within the mounting ring 50, a power supply 331 disposed within the toilet water tank and used to power the ultraviolet lamp tube 51, and a light guide structure 52 disposed within the mounting ring 50. The light guide structure 52 is transparent on both the side near the upper surface of the toilet seat and the side near the lower surface of the toilet seat. With the above-mentioned structure, the ultraviolet lamp tube 51 forms a sterilization effect on both the upper and lower surfaces of the toilet seat, which is highly practical and simple in structure.

By adopting the above structural configuration, with the ratio between H2 and H1 between 0.2 and 0.5, and using a microstructure, a diffuse reflection effect on light is achieved, the light refraction effect is increased, and a good disinfection effect is ensured. The invention is practical and has a simple structure.

[0036] The reflective structure 53, in conjunction with the ultraviolet lamp 51, creates a sterilization effect on the upper and lower surfaces of the toilet seat. A main board structure 530, formed of thermoplastic resin material, is used. The main board structure 530 has an arc-shaped structure A531 and an arc-shaped structure B532 connected to the arc-shaped structure A531 in a direction away from the substrate. The arc-shaped structure A531 is formed of a first resin material and has a convex interface formed by the connecting surfaces of the arc-shaped structure A531 and the arc-shaped structure B532, and a first vertex 533 located on the convex interface. B532 is formed from a second resin material including photosensitive resin and has an outer surface spaced from the convex interface of the arc-shaped structure A531 and a second vertex 534 located on the outer surface, thus achieving a good reflective effect. This facilitates the use of the ultraviolet lamp tube 51 to sterilize the upper surface of the toilet seat. Furthermore, the reflective structure 53 is set along the periphery of the toilet seat, so it does not affect the normal use of the toilet seat. It is highly practical, has a simple structure, and the materials used are designed for light sensitivity, achieving a good sterilization effect, strong stability, and a simple structure.

At this time, the micro-touch switch 32 loses its force, the control circuit 33 forms an open circuit, the electromagnet 330 is de-energized, and the permanent magnet 36 is reset under the action of the reset spring 38. At this time, the cover plate 34 is in the open state, and the disinfectant in the storage cavity 201 flows out.
