Description

Technical Field

[0001] The utility model belongs to the technical field of sterilization and deodorization devices, and particularly relates to a toilet sterilization and deodorization device and a sterilization and deodorization device. Background Technique

[0002] The toilet is an essential appliance in people's lives. It includes a water tank and a toilet bowl (the toilet bowl has a bent pipe connecting to the water tank). When in use, press the water release button, and use the lever principle to lift the water plug. At this time, the water in the water tank will enter the toilet bowl to flush the toilet bowl. After the water level drops to a certain level, the water plug closes, and the water in the water tank no longer enters the toilet bowl. At this time, the floating ball drops to the lowest point, and the switch at this place is turned on, and water enters the water tank from the water supply pipe to replenish water. When it reaches a certain position, the floating ball floats up, and the water supply pipe closes, and the next cycle can be carried out.

[0003] During the use of the toilet, excrement is easily attached to the inner wall of the toilet bowl. Just flushing with clean water is difficult to remove bacteria and the like attached to the inner wall of the toilet bowl, resulting in a large number of bacteria in the toilet bowl and an easy emission of foul odors. People are prone to bacterial infections when using the toilet, which affects people's physical health. Especially in crowded public places (such as shopping malls, hotels, etc.), the toilet is used alternately by many people without disinfection, making it easy for the toilet to breed bacteria and even causing cross-infections among people.

[0004] To solve the above technical problems, disinfectant is added to the water tank, so that the water in the water tank is mixed with the disinfectant to disinfect the toilet while flushing. However, the water output of the water tank is large each time, and the disinfectant is greatly diluted after being put into the water tank, resulting in a poor disinfection effect. In order to make it have a certain disinfection effect, a large amount of disinfectant needs to be added to the water tank, which causes a large consumption of disinfectant and a high disinfection cost, making it difficult to be widely used. Moreover, some design a set of disinfection devices on the toilet, which are completely incompatible with the existing toilets and accessories, and the already installed or produced toilets cannot be used at all. And replacing all the toilets with new models will undoubtedly cause a substantial increase in the use cost of the toilets, making it difficult to promote and use. Content of the Utility Model

The embodiments described below by referring to the drawings are exemplary and are intended to explain the embodiments of the present utility model, and should not be construed as a limitation to the present utility model.

[0046] In an embodiment of the present utility model, referring to Figures 1-8 , a toilet sterilization and odor removal device 10 is provided, which is applied to a toilet and is used to spray water mist with a disinfection effect during operation to sterilize, disinfect, clean, etc. the toilet.

[0047] Referring to Figures 1-8 , the toilet sterilization and odor removal device 10 includes a sterilization and odor removal device main body 100, an electrolysis module 260, an atomization module 250, and a control circuit board 300.

[0048] Among them, referring to Figure 2 and Figure 3 , a water chamber 112, a solution chamber 113, and a working chamber 211 are provided inside the sterilization and odor removal device main body 100. The solution chamber 113 is used to hold brine, and the water chamber 112 is used to hold a liquid, which can be pure water or a mixture of water and other substances.

[0049] Among them, referring to Figure 2 and Figure 3 , the electrolysis module 260 is arranged in the working chamber 211. The electrolysis module 260 divides the working chamber 211 into an atomization area 221 and a solution area 231. The atomization area 221 is communicated with the water chamber 112, and the solution area 231 is communicated with the solution chamber 113.

[0050] Among them, referring to Figure 2 and Figure 3 , an atomization hole 223 communicating with the atomization area 221 is further provided inside the sterilization and odor removal device main body 100. The atomization module 250 is arranged in the atomization hole 223, and an aerosol spray outlet 121 communicating with the atomization hole 223 is opened on the outer wall of the sterilization and odor removal device main body 100.

[0051] Among them, referring to Figure 2 and Figure 3, a control chamber 150 is provided inside the sterilization and deodorization device main body 100. A control circuit board 300 is arranged in the control chamber 150. The electrolysis module 260 and the atomization module 250 are both electrically connected to the control circuit board 300, and the electrolysis module 260 and the atomization module 250 are controlled to work through the control circuit board 300. The control chamber 150 has a certain degree of airtightness to at least ensure that the liquid at positions such as the atomization area 221 and the solution area 231 does not enter the control chamber 150.

[0052] Compared with the prior art, at least one of the above one or more technical solutions provided in the toilet sterilization and deodorization device 10 of the present utility model has the following technical effects:

[0053] Refer to Figure 8 , when in use, the toilet sterilization and deodorization device 10 is fixedly installed on the inner top wall of the toilet lid 510. Of course, in other embodiments, the toilet sterilization and deodorization device 10 can also be installed at other positions of the toilet or fixedly installed on the toilet through other mechanisms.

[0054] Refer to Figure 2 , Figure 3 and Figure 8 , when working, taking the example that there is brine in the solution chamber 113 and clear water in the clear water chamber 112. The brine in the solution chamber 113 is electrolyzed after being energized by the electrolysis module 260 in the solution area 231, so that chloride ions are electrolyzed from the brine in the solution area 231 and transported to the clear water in the atomization area 221. The chloride ions combine (mix) with the clear water in the atomization area 221 to form slightly acidic electrolyzed water mainly composed of hypochlorous acid water. The hypochlorous acid water is atomized through the atomization module 250 to form a water mist with a sterilization and disinfection function. The water mist is sprayed outwards from the aerosol spray outlet 121 to sterilize, disinfect, remove odors, etc. the toilet seat board 520 and the toilet bowl 530, etc., which can effectively reduce the bacteria and odors on the toilet seat board 520 and the toilet bowl 530, bring greater protection to daily life and health, have a low use cost, and can meet the disinfection and deodorization requirements without adding disinfectant.

[0055] Also, refer to Figure 1 and Figure 8 , the toilet sterilization and deodorization device 10 can be applied to various styles of toilets, is easy to promote and use, and has extremely high practicability.

[0056] In another embodiment of the present utility model, refer to Figure 2 and Figure 8, the main body 100 of the sterilization and deodorization device is provided with an attitude sensing module 330, and the attitude sensing module 330 is electrically connected to the control circuit board 300. When the toilet lid 510 is in the closed state, the attitude sensing module 330 is used to turn on the atomization module 250 and the electrolysis module 260. Specifically, when the toilet lid 510 is closed, a relatively closed space is formed between the toilet lid 510 and the toilet bowl 530. In this way, the hypochlorous acid water is atomized through the atomization module 250 to form a water mist with bactericidal and disinfection functions and is sprayed outwards from the aerosol spray outlet 121. The aerosol will not spread outside the toilet, and the toilet seat 520 and the toilet bowl 530 are centrally sterilized, disinfected, deodorized, etc., with better use effects and no need for manual activation, making it more user-friendly. After the atomization module 250 and the electrolysis module 260 operate for a set time, the atomization module 250 and the electrolysis module 260 are turned off, and this set time can be determined according to actual usage requirements. Or, when the user opens the toilet lid 510, the atomization module 250 and the electrolysis module 260 are not turned on or are turned off to prevent the aerosol from spraying on the user.

[0057] In some embodiments, referring to Figure 2 and Figure 8 , the attitude sensing module 330 can be a ball-type attitude switch, but is not limited to a ball-type attitude switch. For example: The main body 100 of the sterilization and deodorization device is fixedly installed on the inner top wall of the toilet lid 510. When the user closes the toilet lid 510 after using the toilet, the ball-type attitude switch senses a position change to another state, that is, the atomization module 250 and the electrolysis module 260 are turned on. At this time, the water mist with bactericidal and disinfection functions is sprayed outwards from the aerosol spray outlet 121 to sterilize, disinfect, deodorize, etc. the toilet seat 520 and the toilet bowl 530. When the user needs to use the toilet and opens the toilet lid 510, the ball-type attitude switch senses that the position returns to the initial state, and the atomization module 250 and the electrolysis module 260 are not turned on or are turned off. Among them, the ball-type attitude switch is a mature existing technology.

[0058] In other embodiments, referring to Figure 2 and Figure 8 , the attitude sensing module 330 can be a photosensitive sensor. For example: The main body 100 of the sterilization and deodorization device is fixedly installed on the inner top wall of the toilet lid 510 or other positions. When the user closes the toilet lid 510 after using the toilet, the photosensitive sensor senses a decrease in light, that is, the atomization module 250 and the electrolysis module 260 are turned on. At this time, the water mist with bactericidal and disinfection functions is sprayed outwards from the aerosol spray outlet 121 to sterilize, disinfect, deodorize, etc. the toilet seat 520 and the toilet bowl 530. When the user needs to use the toilet and opens the toilet lid 510, the photosensitive sensor senses an increase in light, and the atomization module 250 and the electrolysis module 260 are not turned on or are turned off. Among them, the photosensitive sensor is a mature existing technology.

[0059] Of course, the posture sensing module 330 can also be other sensing devices, as long as it can turn on the atomization module 250 and the electrolysis module 260 when the toilet lid 510 is closed, and does not turn on or turns off the atomization module 250 and the electrolysis module 260 when the toilet lid 510 is opened.

[0060] Further, referring to Figure 2 and Figure 8 , a buzzer 310 electrically connected to the control circuit board 300 is further provided inside the sterilization and deodorization device main body 100. Since the toilet lid 510 is in the closed state when the toilet sterilization and deodorization device 10 is working, at this time the user cannot see the toilet sterilization and deodorization device 10, and the working state can be prompted by the sound of the buzzer 310, improving the use experience of the product.

[0061] In another embodiment of the present utility model, referring to Figure 2 and Figure 8 , a touch switch 340 and an indicator light 341 are further provided on the outer wall of the sterilization and deodorization device main body 100. The touch switch 340 and the indicator light 341 are both electrically connected to the control circuit board 300. The touch switch 340 is used to turn on or off the toilet sterilization and deodorization device 10. Specifically, the touch switch 340 is a power on / off key.

[0062] For example, the working procedure can be as follows:

[0063] Referring to Figure 2 and Figure 8 , when the user presses the touch switch 340 once, the posture sensing module 330 is started, the indicator light 341 lights up green for 10 seconds and then goes out. Pressing the touch switch 340 again enters the shutdown state, and the green light goes out, and so on in a cycle.

[0064] Referring to Figure 2 and Figure 8 , when the touch switch 340 is pressed and the indicator light 341 lights up green, at the same time the posture sensing module 330 senses a position change to another state (that is, when the user closes the toilet lid 510), the buzzer 310 makes a beeping sound, and at the same time the atomization module 250 and the electrolysis module 260 are turned on to work for sterilization, disinfection, and odor removal; each time the electrolysis is started, the voltage is 8V and it works for 15 seconds, and after 15 seconds it changes to 5V and works. Each time it is executed for 2 minutes, after 2 minutes the atomization module 250 and the electrolysis module 260 stop working at the same time, and the buzzer 310 makes a beeping sound to end, and so on in a cycle. Pressing the touch switch 340 once in the middle, the atomization module 250 and the electrolysis module 260 stop working at the same time and return to the shutdown state.

[0065] In another embodiment of the present utility model, referring to Figure 2 and Figure 8, the aerosol spray outlet 121 is opened on the side wall of the sterilization and deodorization device main body 100. When the user closes the toilet lid 510 and the sterilization and deodorization device main body 100 is in a substantially horizontal state, when the atomization module 250 and the electrolysis module 260 are turned on, the water mist sprays laterally from the aerosol spray outlet 121. For example, the water mist can spray forward, backward, left or right from the aerosol spray outlet 121. In this way, the water mist with the function of sterilization and disinfection can be better diffused to the seat board 520 and sterilize, disinfect and remove odors from the toilet bowl 530 from top to bottom, and the use effect is better.

[0066] In another embodiment of the present invention, refer to Figure 2 and Figure 3 , the electrolysis module 260 and the atomization module 250 are arranged oppositely, the distance between the electrolysis module 260 and the atomization module 250 is a, and the value of a is a≤30mm. a can be 10mm, 20mm or 30mm, and the value of a can be determined according to actual production requirements or usage requirements. Preferably, the atomization module 250 and the electrolysis module 260 are arranged oppositely.

[0067] The explanation is as follows: Refer to Figure 2 and Figure 3 , the distance a between the atomization module 250 and the electrolysis module 260 is related to the time for generating electrolyzed water meeting the disinfection requirements in the atomization area 221. Therefore, when the value of a is within a suitable range, electrolyzed water meeting the disinfection requirements can be generated in the atomization area 221 in the first time, so that the atomization module 250 can atomize and output water mist meeting the disinfection requirements in the first time. If the value of the distance a is too large and the atomization area 221 is large, the concentration of disinfection substances (such as sodium hypochlorite, hypochlorous acid, ozone, etc.) contained in the electrolyzed water generated in the atomization area 221 for the first time is not enough, resulting in that the electrolyzed water cannot meet the disinfection standard. In this case, the electrolysis module 260 needs to electrolyze for a certain time first to increase the concentration of disinfection substances in the atomization area 221 to the required value before meeting the disinfection requirements. If in public places with a large number of people (such as shopping malls, hotels, etc.), the toilet is used alternately by many people queuing up, and the toilet sterilization and deodorization device 10 can only be started for a short time each time, and the electrolysis amount (concentration of disinfection substances) has not increased yet, then it may cause that the water mist sprayed for each disinfection is non-disinfecting water mist or weakly disinfecting water mist, and the effects of sterilization, disinfection and odor removal cannot be achieved, that is, ineffective disinfection is carried out, and the timeliness is lost.

[0068] Therefore, refer to Figure 2 and Figure 3, in the present application, the distance a between the electrolysis module 260 and the atomization module 250 is set to be ≤ 30 mm, that is, the atomization area 221 is a narrow cavity. The smaller atomization area 221 requires less electrolyzed water (disinfectant) to be prepared each time inside it. In this way, when the electrolysis module 260 electrolyzes, electrolyzed water containing a high concentration of disinfectant substances can be generated in the atomization area 221 in the first place, that is, electrolyzed water meeting the disinfection requirements can be generated in the atomization area 221 in the first place. Moreover, the distance between the electrolysis module 260 and the atomization module 250 is small, and the electrolyzed water meeting the disinfection requirements can reach the atomization module 250 in the first place, enabling the atomization module 250 to atomize and spray out the water mist meeting the disinfection requirements in the first place (in a short time), realizing instant electrolysis and instant atomization, so that the toilet sterilization and odor removal device 10 of the present application achieves the effect of being ready to use immediately, meeting the user's usage requirements.

[0069] Preferably, referring to Figure 3 and Figure 5 , the cross-sectional area of the atomization area 221 is equal to or close to the cross-sectional area of the electrolysis module 260 or the cross-sectional area of the atomization module 250. For example: the cross-sectional area of the atomization area 221 is slightly larger than, equal to, or slightly smaller than the cross-sectional area of the electrolysis module 260, and the cross-sectional area of the atomization area 221 is slightly larger than, equal to, or slightly smaller than the cross-sectional area of the atomization module 250, making the volume of the atomization area 221 small, and electrolyzed water meeting the disinfection requirements can be generated in the atomization area 221 in the first place.

[0070] In some embodiments, the cross-sectional area of the atomization area 221 is less than or equal to twice the cross-sectional area of the electrolysis module 260, or the cross-sectional area of the atomization area 221 is less than or equal to twice the cross-sectional area of the atomization module 250.

[0071] In another embodiment of the present utility model, referring to Figure 2 , when the atomization module 250 and the electrolysis module 260 are in the on state, the distance b between the centers of the atomization module 250 and the electrolysis module 260 and the bottom of the clean water chamber 112 has a value of b ≤ 40 mm. When the centers of both the atomization module 250 and the electrolysis module 260 are higher than the bottom of the clean water chamber 112, the centers of the atomization module 250 and the electrolysis module 260 are not more than 40 mm higher than the bottom of the clean water chamber 112, avoiding excessive remaining water at the bottom of the clean water chamber 112 and causing a poor usage experience. When the centers of both the atomization module 250 and the electrolysis module 260 are lower than the bottom of the clean water chamber 112, the centers of the atomization module 250 and the electrolysis module 260 are not more than 40 mm lower than the bottom of the clean water chamber 112, avoiding an overly large thickness of the sterilization and odor removal device main body 100, which is not practical and affects actual use.

[0072] Similarly, referring to Figure 2, the distance between the centers of the atomization module 250 and the electrolysis module 260 and the bottom of the solution chamber 113 is c, and the value of c is c ≤ 40 mm. When the centers of both the atomization module 250 and the electrolysis module 260 are higher than the bottom of the solution chamber 113, the heights of the centers of the atomization module 250 and the electrolysis module 260 above the bottom of the solution chamber 113 do not exceed 40 mm, so as to avoid excessive residual brine at the bottom of the solution chamber 113 and cause a poor user experience. When the centers of both the atomization module 250 and the electrolysis module 260 are lower than the bottom of the solution chamber 113, the depths of the centers of the atomization module 250 and the electrolysis module 260 below the bottom of the solution chamber 113 do not exceed 40 mm, so as to avoid the main body 100 of the sterilization and deodorization device being too thick and impractical, which affects the actual use.

[0073] Further, referring to Figure 2 and Figure 8 , since the toilet sterilization and deodorization device 10 is fixedly installed on the inner top wall of the toilet lid 510 during use, the thickness of the main body 100 of the sterilization and deodorization device is not easy to be set too thick. Preferably, the main body 100 of the sterilization and deodorization device is a flat shell. For example: the main body 100 of the sterilization and deodorization device is in a flat circular, square or other shapes.

[0074] Further, referring to Figure 2 and Figure 4 , both the clean water chamber 112 and the solution chamber 113 are flat cavities. When the aerosol spray outlet 121 faces sideways, the bottom of the clean water chamber 112 is a large-area bottom surface, and the bottom of the solution chamber 113 is a large-area bottom surface.

[0075] In another embodiment of the present invention, referring to Figure 2 , a liquid level detection module 320 is provided at the bottom of the solution chamber 113. The liquid level detection module 320 is electrically connected to the control circuit board 300, and the liquid level detection module 320 is used to detect the liquid level of the liquid in the solution chamber 113. Since the clean water chamber 112 and the solution chamber 113 of the toilet sterilization and deodorization device 10 of the present application both utilize the characteristic that liquid with a high-low drop flows to a lower place, if the brine in the solution chamber 113 disappears, because there is still water in the clean water chamber 112, the product will continue to electrolyze and atomize, resulting in unqualified electrolyzed disinfected water, causing ineffective spraying and failing to achieve the effects of sterilizing, disinfecting, and deodorizing the toilet. And when the toilet sterilization and deodorization device 10 is working, the toilet lid is in a closed state, and the user cannot observe the aerosol. Therefore, by setting the liquid level detection module 320 to detect the liquid level of the brine in the solution chamber 113, when the liquid in the chamber 110 is insufficient, the user is reminded to add brine to the solution chamber 113 in time, and the safety performance is high. For example: the control circuit board 300 can be electrically connected to a speaker, a buzzer or an indicator light 341, and the user is reminded by means of sound or the indicator light 341. Among them, the liquid level detection module 320 can be a liquid level sensor.

[0076] In another embodiment of the present utility model, refer to Figure 2 and Figure 4 , at least two liquid addition ports 114 are provided at the top of the sterilization and odor removal device main body 100. The two liquid addition ports 114 are respectively communicated with the clean water chamber 112 and the solution chamber 113, and the two liquid addition ports 114 are detachably covered with a cover body 160. When adding liquid, the cover body 160 is removed, and clean water can be added to the clean water chamber 112 and brine can be added to the solution chamber 113 respectively through the two liquid addition ports 114, and the structure is simple. Among them, the material of the cover body 160 can be silicone, rubber or latex.

[0077] Furthermore, refer to Figure 1 and Figure 4 , at least one exhaust hole 115 is formed at the top of the sterilization and odor removal device main body 100 in both the clean water chamber 112 and the solution chamber 113. The exhaust hole 115 is covered with a waterproof and breathable membrane 116. The waterproof and breathable membrane 116 can not only discharge the gas in the clean water chamber 112 and the solution chamber 113, but also prevent the liquid in the clean water chamber 112 and the solution chamber 113 from leaking out through the exhaust hole 115. Among them, the waterproof and breathable membrane 116 (breathing paper) is a new type of polymer waterproof material and belongs to the mature prior art.

[0078] In another embodiment of the present utility model, refer to Figure 2 , a battery 350 is further provided in the control chamber 150. The battery 350 is electrically connected to the control circuit board 300, and the control circuit board 300, the attitude sensing module 330, the touch switch 340, the indicator light 341, the liquid level detection module 320, the electrolysis module 260 and the atomization module 250 are powered by the battery 350.

[0079] Furthermore, refer to Figure 2 , a charging interface 351 is embedded on the outer wall of the sterilization and odor removal device main body 100. The charging interface 351 is connected to an external power supply through a data cable to charge the battery 350.

[0080] In another embodiment of the present utility model, refer to Figure 1 and Figure 4, the toilet sterilization and odor removal device 10 further includes a mounting base 170. The mounting base 170 is detachably and fixedly connected to the sterilization and odor removal device main body 100, and the mounting base 170 is used to be fixed on the inner top wall of the toilet lid 510. In use, one side of the mounting base 170 facing away from the sterilization and odor removal device main body 100 can be fixedly adhered to the inner top wall of the toilet lid 510 by means of double-sided tape, glue, etc. The installation is convenient, so that the toilet sterilization and odor removal device 10 can be applied to various styles of toilets, is easy to promote and use, and has extremely high practicability. When the brine in the solution chamber 113 and / or the clear water in the clear water chamber 112 are used up or nearly used up, the user disassembles the sterilization and odor removal device main body 100 from the mounting base 170, and adds brine to the solution chamber 113 through one of its liquid filling ports 114 and / or adds clear water to the clear water chamber 112 through the other liquid filling port 114, which is convenient to use. Also, when the battery 350 runs out of power, the sterilization and odor removal device main body 100 can also be removed, and the charging interface 351 can be connected to an external power supply through a data cable to charge the battery 350.

[0081] Further, referring to Figure 1 and Figure 4 , one of the mounting base 170 and the sterilization and odor removal device main body 100 is provided with a snap buckle 172, and the other is provided with a snap groove 101. The snap buckle 172 and the snap groove 101 are detachably snapped together, so that the mounting base 170 and the sterilization and odor removal device main body 100 are detachably and fixedly connected, facilitating the disassembly and assembly of the sterilization and odor removal device main body 100.

[0082] Specifically, referring to Figure 1 and Figure 4 , two protruding parts 171 are symmetrically provided on one side of the mounting base 170 close to the sterilization and odor removal device main body 100, and two snap buckles 172 are respectively arranged on the two protruding parts 171. Two snap grooves 101 are symmetrically provided on the top of the sterilization and odor removal device main body 100, and the two snap buckles 172 are respectively detachably snapped into the two snap grooves 101, so that the mounting base 170 and the sterilization and odor removal device main body 100 are stably snapped together.

[0083] Even further, referring to Figure 1 and Figure 4 , a disassembly and assembly opening 102 is opened at one end of the snap groove 101 on the top of the sterilization and odor removal device main body 100. During installation, the two snap buckles 172 are respectively inserted into the two disassembly and assembly openings 102, and then the sterilization and odor removal device main body 100 is pushed, and the two snap buckles 172 can be snapped into the two snap grooves 101. During disassembly, the sterilization and odor removal device main body 100 is pushed so that the two snap buckles 172 are respectively moved from the two snap grooves 101 to the two disassembly and assembly openings 102, and the sterilization and odor removal device main body 100 can be removed.

[0084] Even further, referring to Figure 1 and Figure 4, the slot wall of the card slot 101 is provided with card teeth, and the outer wall of the card buckle 172 is provided with tooth grooves. Since the two protruding parts 171 have a certain elasticity, when a user applies an external force to push the sterilization and deodorization device main body 100, the card teeth can be engaged or disengaged with the tooth grooves. Since the toilet sterilization and deodorization device 10 moves along with the toilet lid 510 during use, the sterilization and deodorization device main body 100 is firmly connected to the mounting seat 170 through the engagement of the card teeth and the tooth grooves, so that the sterilization and deodorization device main body 100 is not easily dropped.

[0085] Alternatively, in other embodiments, one of the mounting seat 170 and the sterilization and deodorization device main body 100 is provided with a magnet (not shown in the figure), and the other is provided with a magnetic member (not shown in the figure). The magnetic member is another magnet or a metal (such as iron) that is magnetically attracted to the magnet. The magnet and the magnetic member are magnetically attracted to each other, so that the mounting seat 170 and the sterilization and deodorization device main body 100 are detachably and fixedly connected, facilitating the disassembly and assembly of the sterilization and deodorization device main body 100.

[0086] In another embodiment of the present invention, refer to Figure 3 and Figure 4 , a main housing 210 is provided inside the sterilization and deodorization device main body 100. Specifically, an installation cavity 130 is provided inside the sterilization and deodorization device main body 100. An installation port 132 communicating with the control chamber 150 is opened on the cavity wall of the installation cavity 130. The main housing 210 is installed in the installation cavity 130 through the installation port 132, and the main housing 210 is fixedly installed in the installation cavity 130 by screwing or fixing members 133.

[0087] Further, refer to Figures 5-7 , the main housing 210 includes an atomization housing 220 and an electrolysis housing 230.

[0088] Among them, refer to Figures 5-7 , the atomization holes 223 are opened at one end of the atomization housing 220. An atomization area 221 is provided inside the atomization housing 220. A first cavity opening 224 is formed at the other end of the atomization area 221. The first cavity opening 224 and the atomization holes 223 are arranged opposite to each other. A current-limiting hole 222 communicating with the atomization area 221 is opened on the outer wall of the atomization housing 220. The atomization area 221 is communicated with the clear water cavity through the current-limiting hole 222. First liquid inlet holes 112a corresponding to the current-limiting holes 222 one by one are opened on the cavity wall of the clear water cavity. The clear water in the clear water cavity flows into the atomization area 221 through the first liquid inlet holes 112a and the current-limiting holes 222.

[0089] Among them, refer to Figures 5-7, the electrolysis housing 230 has a solution area 231. A second cavity opening 234 is formed at one end of the solution area 231 in the electrolysis housing 230, and the electrolysis module 260 is arranged at the second cavity opening 234. A solution channel 232 communicating with the solution area 231 is formed on the outer wall of the electrolysis housing 230. The solution area 231 is communicated with the solution cavity through the solution channel 232. Second liquid inlet holes 113a corresponding to the solution channel 232 one by one are formed on the cavity wall of the solution cavity. The brine in the solution cavity flows into the solution area 231 through the second liquid inlet holes 113a and the solution channel 232.

[0090] Among them, referring to Figures 5-7 , one end of the atomization housing 220 having a first cavity opening 224 is connected to one end of the electrolysis housing 230 having a second cavity opening 234. A connecting ring 240 is arranged between the atomization housing 220 and the electrolysis housing 230. The connecting ring 240 is used to fixedly install the electrolysis module 260 in the second cavity opening 234. By setting the main housing 210 into a combined structure of the atomization housing 220 and the electrolysis housing 230, it is convenient to install the electrolysis module 260 and the atomization module 250 in the main housing 210 during production and processing.

[0091] Furthermore, referring to Figure 7 , the atomization module 250 includes a microporous atomization sheet 251 arranged at the atomization holes 223. Two second leads 252 are arranged on the microporous atomization sheet 251. Both of the two second leads 252 extend out of the main housing 210 and are electrically connected to the control circuit board 300.

[0092] Among them, referring to Figure 7 , the microporous atomization sheet 251 utilizes electronic high-frequency oscillation. Through the high-frequency resonance of the microporous atomization sheet 251, the liquid water molecular structure is broken up to generate natural floating water mist, without heating or adding any chemical reagents, and the structure is simple and compact, without occupying too much space. The microporous atomization sheet 251 is a mature existing technology.

[0093] Furthermore, referring to Figure 6 , the electrolysis module 260 includes a diaphragm 262 and two electrode plates 261 respectively arranged on both sides of the diaphragm 262. The two electrode plates 261 are respectively a positive electrode plate and a negative electrode plate. A first lead 261a is arranged on each of the positive electrode plate and the negative electrode plate. Both of the two first leads 261a extend out of the main housing 210 and are electrically connected to the control circuit board 300. Hollow parts 261b are arranged in the middle of the two electrode plates 261, and at least one through hole 261c is arranged through the hollow parts 261b.

[0094] The electrolysis generates weakly acidic electrolyzed water (hypochlorous acid water) as follows:

[0095] Referring to Figure 5 and Figure 6The positive electrode sheet contacts the clean water in the atomization area 221, the negative electrode sheet contacts the salt water in the solution area 231, and the diaphragm 262 is an anion exchange membrane. When the electrolysis module 260 is powered on, electrolysis occurs, and the sodium chloride (NaCl) and water (H2O) in the salt water are ionized to generate hydrogen (H2) and chlorine (Cl2) at the cathode and anode, respectively, and the hydroxide ions combine with the sodium ions to generate sodium hydroxide (NaOH). Among them, the negative electrode produces chloride ions, which are anions and can enter the clean water in the atomization area 221 through the anion exchange membrane, while cations cannot pass through the anion exchange membrane. The chloride ions are combined (mixed) with the clean water in the atomization area 221 to form slightly acidic electrolyzed water mainly composed of hypochlorous acid water. The chloric acid water is atomized by the atomization module 250 to form a water mist with a sterilization and disinfection function. The water mist is sprayed outward from the aerosol spray port 121 to sterilize, disinfect, and remove odors on the toilet seat 520 and the toilet bowl 530, etc., which can effectively reduce the bacteria and odors on the toilet seat 520 and the toilet bowl 530, provide greater protection for daily life and health, have low use costs, and can meet the disinfection and odor removal needs without the need to add disinfectant.

[0096] Further, refer to Figure 5 and Figure 7 A first sealing ring 264 and a second sealing ring 265 are respectively provided on the periphery of one end of the two electrode sheets 261 away from the diaphragm. The connecting ring 240 is used to compress the first sealing ring 264, the positive electrode sheet, the diaphragm, the negative electrode sheet and the second sealing ring 265 to seal each other. The first sealing ring 264 and the second sealing ring 265 are used to seal the four sides of the two electrode sheets 261 to prevent the liquid in the atomization area 221 and the solution area 231 from seeping to the outside of the electrolysis module 260 to cause a short circuit, and at the same time prevent water leakage, and the sealing performance is good.

[0097] Further, refer to Figure 6 The electrode sheet 261 includes an outer frame portion and a hollow portion 261b in the middle. The outer frame portion serves as a supporting and connecting structure for the electrode sheet 261, and the hollow portion 261b is in contact with the liquid. The hollow portion 261b has at least one through hole 261c to ensure that the liquid (such as water, salt water, or a mixture of water and other substances) can pass through the through hole 261c of the hollow portion 261b to contact the diaphragm 262. The electrode sheet 261 is connected to the periphery of the diaphragm 262 through the outer frame portion.

[0098] Furthermore, refer to Figure 6 The hollow part 261b is a strip structure, which forms a grid shape. Gaps are left between the strip structures as through holes 261c. This design greatly increases the contact area between the liquid and the electrode sheet 261, which has higher electrolysis efficiency and is easy to clean.

[0099] In other embodiments, the electrode sheet 261 includes a conductive plate and an electrode attached to the conductive plate. By providing the conductive plate, the cost of the electrode sheet 261 can be greatly reduced because it is difficult to process and apply a metal coating to a very small titanium electrode sheet 261.

[0100] In some embodiments, the electrode sheet 261 can be replaced with different electrode materials. For example, a titanium electrode, a titanium ruthenium iridium coating, a titanium platinum coating, or a BDD diamond electrode can be used to achieve different electrolysis effects and substances.

[0101] Further, referring to Figures 5-7 , one of the inner wall of the first cavity 224 and the outer wall of one end of the connecting ring 240 is provided with a plurality of first clamping grooves 225, and the other is provided with a plurality of first clamping blocks 241. The plurality of first clamping blocks 241 are respectively adapted and clamped with the plurality of first clamping grooves 225, so that one end of the connecting ring 240 is fixedly clamped in the first cavity 224. The structure is simple and convenient for disassembly and assembly. In a specific embodiment, the plurality of first clamping grooves 225 are annularly arranged on the inner wall of the first cavity 224, and the plurality of first clamping blocks 241 are annularly arranged on the outer wall of one end of the connecting ring 240.

[0102] Further, referring to Figures 5-7 , the other end of the connecting ring 240 is provided with a connecting portion 242. One of the connecting portion 242 and the outer wall of one end of the electrolysis housing 230 having a second cavity 234 is provided with a plurality of second clamping grooves 243, and the other is provided with a plurality of second clamping blocks 235. The plurality of second clamping blocks 235 are respectively adapted and clamped with the plurality of second clamping grooves 243, so that the other end of the connecting ring 240 is fixedly clamped to the electrolysis housing 230 and tightly presses the first sealing ring 264, the positive electrode sheet, the diaphragm, the negative electrode sheet, and the second sealing ring 265 to be hermetically fitted to each other. The structure is simple and convenient for disassembly and assembly. In a specific embodiment, the plurality of second clamping grooves 243 are annularly arranged on the connecting portion 242, and the plurality of first clamping blocks 241 are annularly arranged on the outer wall of one end of the electrolysis housing 230 having a second cavity 234.

[0103] Of course, the connecting ring 240 can also be fixedly connected to the atomizing housing 220 and the electrolysis housing 230 by means of screwing, welding, or bonding, etc., which is not limited herein.

[0104] Further, referring to Figures 5-7 , a first sealing sleeve 270 is sleeved outside the electrolysis housing 230. The first sealing sleeve 270 is provided with a clearance hole for avoiding the solution channel 232 and the second liquid inlet hole 113a. The first sealing sleeve 270 is used for hermetically abutting against the cavity wall of the installation cavity 130 to improve the sealing performance and prevent liquid from overflowing between the installation cavity 130 and the electrolysis housing 230. The structure is reliable.

[0105] Further, referring to Figure 2 and Figure 3, one end of the atomizing housing 220 having atomizing holes 223 is in sealing abutment with the wall of the installation cavity 130, preventing liquid from overflowing between the installation cavity 130 and the atomizing housing 220, and the structure is reliable.

[0106] In some embodiments, referring to Figure 3 and Figure 4 , the sterilizing and deodorizing device main body 100 includes a top housing 103, a middle housing 104, and a bottom housing 105; the top housing 103, the middle housing 104, and the bottom housing 105 are combined to form the sterilizing and deodorizing device main body 100, and a fresh water cavity 112, a solution cavity 113, and a control compartment 150 are formed inside the sterilizing and deodorizing device main body 100, which is convenient for processing and the installation of each component.

[0107] In another embodiment of the present utility model, a sterilizing and deodorizing device is further provided, which is applied to scenarios such as shoe cabinets, storage cabinets, and wash cabinets, and is used to spray water mist with a disinfection effect during operation for sterilization, disinfection, cleaning, etc.

[0108] The sterilizing and deodorizing device includes a sterilizing and deodorizing device main body 100, an electrolysis module 260, an atomization module 250, and a control circuit board 300.

[0109] Among them, referring to Figure 1 and Figure 2 , a cavity 110, a control compartment 150, and atomizing holes 223 are provided inside the sterilizing and deodorizing device main body 100, and the cavity 110 is used to hold brine, fresh water, or a mixed liquid of water and other substances.

[0110] Among them, referring to Figure 1 and Figure 2 , the electrolysis module 260 is disposed in the cavity 110, and the electrolysis module 260 is used to electrolyze the liquid in the cavity 110 to form electrolyzed water.

[0111] Among them, referring to Figure 1 and Figure 2 , the atomizing holes 223 are communicated with the cavity 110, and the atomization module 250 is disposed in the atomizing holes 223 to atomize the electrolyzed water to form a mist, and a mist outlet 121 communicating with the atomizing holes 223 is opened on the outer wall of the sterilizing and deodorizing device main body 100.

[0112] Furthermore, the disinfection device main body 100 is provided with an identification module (not shown in the figure), and the identification module is electrically connected to the control circuit board to open or close the atomization module and the electrolysis module. There is no need to manually turn on or off the atomization module and the electrolysis module, which is not only convenient to use, but also greatly improves the user experience.

[0113] For example, the recognition module can be an infrared sensor. When the user closes the cabinet door, the recognition module senses the closing of the cabinet door, and then the atomization module 250 and the electrolysis module 260 are activated, and a water mist with a sterilization and disinfection function is sprayed into the cabinet from the aerosol spray outlet 121 for spray disinfection. When the user opens the cabinet door, the atomization module 250 and the electrolysis module 260 are closed.

[0114] For example, the recognition module can be a photosensitive sensor. When the cabinet door is closed, the photosensitive sensor senses that the light inside the cabinet becomes darker, and the atomization module 250 and the electrolysis module 260 are activated, and a water mist with a sterilization and disinfection function is sprayed into the cabinet from the aerosol spray outlet 121 for spray disinfection. When the user opens the cabinet door, the atomization module 250 and the electrolysis module 260 are closed. Alternatively, when the instant electrolytic spray disinfector is placed in a relatively dark place, and then the door is opened or the light is turned on, indicating that someone has entered, the photosensitive sensor senses the increase in light, and the atomization module 250 and the electrolysis module 260 are activated.

[0115] For example, the recognition module can be an image sensor. For example, when the image sensor senses the closing of the cabinet door, the atomization module 250 and the electrolysis module 260 are activated for spray disinfection. Conversely, when the image sensor senses the opening of the cabinet door, the atomization module 250 and the electrolysis module 260 are not activated or are closed.

[0116] Specifically, the outer wall of the disinfector main body 100 is provided with an installation hole, and a light-transmitting window is embedded in the installation hole. The recognition module is arranged inside the disinfector main body, and the sensing end of the recognition module is close to and faces the light-transmitting window.

[0117] Among them, the control circuit board 300 is provided with a power detection module (not shown in the figure), and the power detection module is used to detect the power of the electrolysis module 260. When the electrolysis module 260 has an abnormal contact, the power of the electrolysis module 260 will also be abnormal, which will cause insufficient electrolysis power and affect the concentration of the disinfection water generated by electrolysis. Therefore, by setting the power detection module to detect the power of the electrolysis module 260, when the power detection module detects an abnormal decrease in the electrolysis power, an alarm prompt is issued (for example: the alarm prompt can be made by means of sound or an indicator light, etc.); or, since a coating is applied to the surface of the electrode plate 261 of the electrolysis module 260, and this coating is not permanent, if the coating on the surface of the electrode plate 261 ages or falls off, the electrolysis power of the electrolysis module 260 will also decrease, and the concentration of the disinfection water generated by electrolysis will not meet the standard. Therefore, the power detection module is used to detect the power of the electrolysis module 260, and when the electrolysis power abnormally decreases, the user is alarmed to replace or repair the parts, which has extremely high practicality. Among them, the power detection module is a mature existing technology, and its structure and working principle will not be elaborated here.

[0118] Among them, referring to Figure 2, the control circuit board 300 can be set by using an integrated chip according to actual production needs. Since the control circuit board 300 belongs to a technology that has been formed and matured in the prior art, how the control circuit board 300 controls the toilet sterilization and odor removal device 10 should be well-known and mastered by those skilled in the art. Therefore, the control principle thereof will not be elaborated herein in the present utility model.

[0119] The rest of this embodiment is the same as that of the first embodiment. For the features not explained in this embodiment, the explanations of the first embodiment are adopted and will not be elaborated herein.

[0120] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, its architecture form can be flexible and variable, and a series of products can be derived. Just making several simple deductions or substitutions should be regarded as belonging to the patent protection scope of the present utility model determined by the submitted claims.
