Description

Technical Field

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

[0002] A 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, by pressing the flushing button, the water plug is lifted using the lever principle. At this time, the water in the water tank enters 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 float ball drops to the lowest point, and the switch at this place is turned on. Water enters the water tank through the water supply pipe to replenish water. When it reaches a certain position, the float 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 likely to adhere to the inner wall of the toilet bowl. Just flushing with clean water is difficult to remove bacteria and the like adhering 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 bacteria to breed in the toilet 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 while flushing the toilet. 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 popularized. Additionally, some designs a set of disinfection devices on the toilet, which is completely incompatible with existing toilets and their accessories, and toilets that have already been installed or produced cannot be used at all. And replacing all toilets with new models will undoubtedly cause a substantial increase in the usage cost of the toilets, making it difficult to be promoted. Summary of the Utility Model

[0039] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference 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.

[0040] In one embodiment of the present utility model, referring to Figures 1-5 , 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, and clean the toilet, etc.

[0041] Referring to Figures 1-5 , 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.

[0042] Among them, referring to Figure 1 and Figure 2 , a cavity 110, a control chamber 150, and atomization holes 223 are provided in the sterilization and odor removal device main body 100. The cavity 110 is used to hold brine, clean water, or a mixed solution of water and other substances.

[0043] 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.

[0044] Among them, referring to Figure 1 and Figure 2 , the atomization holes 223 are communicated with the cavity 110, and the atomization module 250 is disposed in the atomization holes 223 to atomize the electrolyzed water to form an aerosol. An aerosol spray outlet 121 communicating with the atomization holes 223 is formed on the outer wall of the sterilization and odor removal device main body 100.

[0045] Among them, referring to Figure 1 and Figure 2 , the control circuit board 300 is disposed 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 sealing property to at least ensure that the liquid at the position of the cavity 110 does not enter the control chamber 150.

[0046] Compared with the prior art, at least one of the above one or more technical solutions in the toilet sterilization and odor removal device 1010 provided by the embodiments of the present utility model has the following technical effects:

[0047] Reference Figure 5 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.

[0048] Reference Figure 2 And Figure 5 When working, taking the brine in the cavity 110 as an example. After the electrolysis module 260 is powered on, the brine in the cavity 110 undergoes electrolysis. First, chlorine gas Cl2 and sodium hydroxide NaOH are generated by the reaction, and then sodium hypochlorite NaClO is obtained by the reaction of chlorine gas Cl2 and sodium hydroxide NaOH. Sodium hypochlorite NaClO combines (mixes) with clean water to form electrolyzed water mainly composed of sodium hypochlorite solution. The electrolyzed water is atomized by the atomization module 250 to form water mist with bactericidal and disinfection functions. The water mist is sprayed outwards from the aerosol spray outlet 121 to sterilize, disinfect, remove odors, etc. the toilet seat 520 and the toilet bowl 530, etc., which can effectively reduce bacteria and odors on the toilet seat 520 and the toilet bowl 530, bring greater protection to daily life and health, have low usage costs, and can meet the disinfection and deodorization requirements without adding disinfectant.

[0049] In addition, referring to Figure 1 And Figure 5 This toilet sterilization and deodorization device 10 can be applied to various styles of toilets, is easy to promote and use, and has extremely high practicality.

[0050] In another embodiment of the present utility model, referring to Figure 2 And Figure 5 The sterilization and deodorization device main body 100 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 by the atomization module 250 to form water mist with bactericidal and disinfection functions and is sprayed outwards from the aerosol spray outlet 121, and the aerosol will not spread outside the toilet, and the toilet seat 520 and the toilet bowl 530 are sterilized, disinfected, deodorized, etc. intensively, with better use effects and no need to be manually turned on, making it more user-friendly. After the atomization module 250 and the electrolysis module 260 run for a set time, the atomization module 250 and the electrolysis module 260 are turned off, and the 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.

[0051] In some embodiments, referring to Figure 2 And Figure 5, the posture sensing module 330 can be a ball-type posture switch 340, but is not limited to the ball-type posture switch. For example: the main body 100 of the sterilization and odor removal 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 posture switch 340 senses the 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 sterilization and disinfection functions is sprayed out from the aerosol nozzle 121 to sterilize, disinfect, and remove odors from the toilet seat 520 and the toilet bowl 530. When the user wants to use the toilet and opens the toilet lid 510, the ball-type posture switch 340 senses that the position returns to the initial state, and does not turn on or turn off the atomization module 250 and the electrolysis module 260. Among them, the ball-type posture switch 340 is a mature existing technology.

[0052] In other embodiments, referring to Figure 2 and Figure 5 , the posture sensing module 330 can be a photosensitive sensor. For example: the main body 100 of the sterilization and odor removal 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 that the light becomes darker, that is, the atomization module 250 and the electrolysis module 260 are turned on. At this time, the water mist with sterilization and disinfection functions is sprayed out from the aerosol nozzle 121 to sterilize, disinfect, and remove odors from the toilet seat 520 and the toilet bowl 530. When the user wants to use the toilet and opens the toilet lid 510, the photosensitive sensor senses that the light becomes brighter, and does not turn on or turn off the atomization module 250 and the electrolysis module 260. Among them, the photosensitive sensor is a mature existing technology.

[0053] 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 turn off the atomization module 250 and the electrolysis module 260 when the toilet lid 510 is opened.

[0054] Furthermore, referring to Figure 2 and Figure 5 , a buzzer 310 electrically connected to the control circuit board 300 is further provided in the main body 100 of the sterilization and odor removal device. Specifically, the buzzer 310 is arranged in the control chamber 150. Since the toilet lid 510 is in a closed state when the toilet sterilization and odor removal device 10 is working, at this time the user cannot see the toilet sterilization and odor removal device 10, and the sound of the buzzer 310 can be used to prompt the working state, improving the user experience of the product.

[0055] In another embodiment of the present utility model, referring to Figure 2 and Figure 5, an outer wall of the sterilization and deodorization device main body 100 is further provided with a switch 340 and an indicator light 341. Both the switch 340 and the indicator light 341 are electrically connected to the control circuit board 300. The switch 340 is used to turn on or off the toilet sterilization and deodorization device 10. Specifically, the switch 340 is a switch 340 key.

[0056] For example, the working procedure can be as follows:

[0057] Refer to Figure 2 and Figure 5 , when the user presses the switch 340 once, the posture sensing module 330 is activated, and the indicator light 341 turns on and then turns off after a few seconds. Pressing the switch 340 again enters the shutdown state, and the green light goes out, cycling in turn.

[0058] Refer to Figure 2 and Figure 5 , when the switch 340 is pressed and the indicator light 341 turns on green, at the same time, when 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 starts with an execution starting voltage of 8V for 15 seconds, and then switches to 5V for work after 15 seconds. Each execution lasts 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, cycling in turn. Pressing the 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.

[0059] In another embodiment of the present invention, refer to Figure 2 and Figure 5 , 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, it can better spread the water mist with sterilization and disinfection functions to the seat board 520 and sterilize, disinfect, and remove odors from the toilet bowl 530 from top to bottom, with better use effects.

[0060] In another embodiment of the present invention, refer to Figure 2, when the atomization module 250 and the electrolysis module 260 are in the on state, the distance between the center of the atomization module 250 and the bottom of the cavity 110 is b, and the value of b is b ≤ 40 mm. When the center of the atomization module 250 is higher than the bottom of the cavity 110, the center of the atomization module 250 is not more than 40 mm higher than the bottom of the cavity 110, so as to avoid excessive remaining water at the bottom of the cavity 110 and cause a poor user experience. When the center of the atomization module 250 is lower than the bottom of the cavity 110, the center of the atomization module 250 is not more than 40 mm lower than the bottom of the cavity 110, so as to avoid the excessive thickness of the main body 100 of the sterilization and deodorization device, which is not practical and affects the actual use.

[0061] Further, referring to Figure 2 and Figure 5 , 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.

[0062] Further, referring to Figure 2 , the cavity 110 is a flat cavity. When the aerosol spray outlet 121 faces laterally, the bottom of the cavity 110 is a large-area bottom surface.

[0063] In another embodiment of the present invention, referring to Figure 2 , a liquid level detection module 320 is provided at the bottom of the cavity 110. The liquid level detection module 320 is electrically connected to the control circuit board 300. The liquid level detection module 320 is used to detect the liquid level of the liquid in the solution cavity. Since the cavity 110 of the toilet sterilization and deodorization device 10 of the present application adopts the characteristic that the liquid flows to the lower place with a high and low drop, and when the toilet sterilization and deodorization device 10 is working, the toilet lid is in the closed state and the user cannot observe the aerosol, the liquid level detection module 320 is set to detect the liquid level of the liquid (such as brine or clear water) in the cavity 110. When the liquid in the cavity 110 is insufficient, the user is reminded to add liquid to the solution cavity in time. 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.

[0064] In another embodiment of the present invention, referring to Figure 2 and Figure 4, at least one liquid addition port 114 is provided at the top of the sterilization and odor removal device main body 100. The liquid addition port 114 is communicated with the cavity 110, and the liquid addition port 114 is detachably covered with a cover body 160. When adding liquid, the cover body 160 is removed, and liquid (such as brine or clear water) can be added into the cavity 110 through the liquid addition port 114, and the structure is simple. Among them, the material of the cover body 160 can be silica gel, rubber or latex.

[0065] Further, referring to Figure 1 and Figure 3 , at least one exhaust hole 115 is formed at the top of the sterilization and odor removal device main body 100 in the cavity 110. The exhaust hole 115 is covered with a waterproof breathable film 116. The waterproof breathable film 116 can not only discharge the gas in the cavity 110, but also prevent the liquid in the cavity 110 from leaking out through the exhaust hole 115. Among them, the waterproof breathable film 116 (breathing paper) is a new type of polymer waterproof material and belongs to the mature existing technology.

[0066] In another embodiment of the present utility model, referring 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 battery 350 supplies power to the control circuit board 300, the attitude sensing module 330, the switch 340, the indicator light 341, the liquid level detection module 320, the electrolysis module 260 and the atomization module 250.

[0067] Further, referring to Figure 3 , 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.

[0068] In another embodiment of the present utility model, referring to Figure 1 and Figure 3 , the toilet sterilization and odor removal device 10 further includes a mounting seat 170. The mounting seat 170 is detachably and fixedly connected to the sterilization and odor removal device main body 100. The mounting seat 170 is used to be fixed on the inner top wall of the toilet lid 510. During use, one side of the mounting seat 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 or 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 cavity and / or the clear water in the clear water cavity are used up or nearly used up, the user disassembles the sterilization and odor removal device main body 100 from the mounting seat 170, and adds brine into the solution cavity through one of its liquid addition ports 114 and / or adds clear water into the clear water cavity through the other liquid addition 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 is connected to an external power supply through a data cable to charge the battery 350.

[0069] Further, referring to Figure 1 and Figure 3 , one of the mounting base 170 and the sterilization and deodorization 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 deodorization device main body 100 are detachably and fixedly connected, facilitating the disassembly and assembly of the sterilization and deodorization device main body 100.

[0070] Specifically, referring to Figure 1 and Figure 3 , two protruding portions 171 are symmetrically provided on one side of the mounting base 170 close to the sterilization and deodorization device main body 100. Two snap buckles 172 are respectively arranged on the two protruding portions 171. Two snap grooves 101 are symmetrically provided on the top of the sterilization and deodorization device main body 100. The two snap buckles 172 are respectively detachably snapped with the two snap grooves 101, so that the mounting base 170 and the sterilization and deodorization device main body 100 are stably snapped together.

[0071] Even further, referring to Figure 1 and Figure 3 , a disassembly and assembly opening 102 is formed at one end of the snap groove 101 on the top of the sterilization and deodorization 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 deodorization 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 deodorization 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 deodorization device main body 100 can be removed.

[0072] Even further, referring to Figure 1 and Figure 3 , the groove wall of the snap groove 101 is provided with engaging teeth, and the outer wall of the snap buckle 172 is provided with tooth grooves. Since the two protruding portions 171 have a certain elasticity, when a user applies an external force to push the sterilization and deodorization device main body 100, the engaging 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 and the mounting base 170 are firmly connected by the engagement of the engaging teeth and the tooth grooves, so that the sterilization and deodorization device main body 100 is not easily dropped.

[0073] Alternatively, in other embodiments, one of the mounting base 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 base 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.

[0074] In another embodiment of the present invention, referring toFigure 1 and Figure 2 , the atomization module 250 includes a microporous atomization sheet 251 provided at the atomization hole 223. The microporous atomization sheet 251 is provided with two second power connection terminals, and both second power connection terminals are electrically connected to the control circuit board 300.

[0075] Among them, referring to Figure 2 , the microporous atomization sheet 251 uses 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 and floating water mist, without heating or adding any chemical reagents, and has a simple and compact structure without occupying too much space. The microporous atomization sheet 251 is a mature existing technology.

[0076] Furthermore, referring to Figure 2 , an installation hole 106 is formed in the outer wall of the main body 100 of the sterilization and deodorization device. The inner end of the installation hole 106 is communicated with the cavity 110 through a flow channel 107. An annular seat 220 is provided near the flow channel 107 of the installation hole 106. The annular hole of the annular seat 220 is the atomization hole 223. The liquid in the cavity 110 flows to the microporous atomization sheet 251 at the atomization hole 223 through the flow channel 107. A through hole is formed in the hole wall of the atomization hole 223, and the two second power connection terminals of the microporous atomization sheet 251 pass through the through hole and are electrically connected to the control circuit board 300. A sealing sleeve 120 is embedded at the outer end of the installation hole 106, and the sleeve hole of the sealing sleeve 120 is the aerosol outlet 121. The sealing sleeve 120 is hermetically abutted against the annular seat 220 to play a sealing role and prevent the liquid from overflowing between the annular seat 220 and the installation hole 106, and the structure is reliable.

[0077] Furthermore, referring to Figure 2 and Figure 4 , the electrolysis module 260 includes an intermediate member 262 and two electrode plates 261 respectively provided on both sides of the intermediate member 262. The two electrode plates 261 are a positive electrode plate and a negative electrode plate respectively. The positive electrode plate and the negative electrode plate are both provided with a first power connection terminal 261a, and both first power connection terminals 261a extend into the control chamber 150 and are electrically connected to the control circuit board 300. The middle parts of the two electrode plates 261 are both provided with hollowed-out parts 261b, and at least one through hole 261c is formed through the hollowed-out parts 261b. The hollowed-out parts 261b are in a mesh structure or a strip structure, and the mesh structure or the strip structure forms a grid shape. This design greatly increases the contact surface between the liquid and the electrode plate 261, has a higher electrolysis efficiency, and is easy to clean. The intermediate member 262 is a diaphragm or a bracket, and the intermediate member 262 is used to separate the positive electrode plate from the negative electrode plate to prevent the positive electrode plate and the negative electrode plate from contacting each other and causing a short circuit.

[0078] In other embodiments, the material of the electrode sheet 261 is one of conductive silicon or conductive diamond, or it can also be one of the elemental substances of titanium, platinum, lead, tantalum, ruthenium, iridium, palladium, antimony or their oxide materials, achieving different electrolysis effects and substances. The material is not limited herein and is subject to the electrolysis requirements.

[0079] Referring to Figure 2 and Figure 4 , when the middle piece 262 is a bracket, brine is placed in the cavity 110. After the electrolysis module 260 is powered on, the brine in the cavity 110 undergoes electrolysis to generate electrolyzed water mainly composed of sodium hypochlorite solution. The electrolyzed water is atomized by the atomization module 250 to form a water mist with a sterilization and disinfection function, and the water mist is ejected outward from the aerosol spray outlet 121 to sterilize, disinfect, remove odors, etc. the toilet seat board 520, the toilet bowl 530, etc.

[0080] When the middle piece 262 is a diaphragm, the diaphragm is a proton exchange membrane, etc., and the electrode sheet 261261 is conductive diamond. Fresh water is placed in the cavity 110. After the electrolysis module 260 is powered on, the fresh water in the cavity 110 undergoes electrolysis.

[0081] The positive electrode reaction is:

[0082] 3O2 + 6H+ + 6e- = 3H2O2

[0083] The negative electrode reaction is:

[0084] 3H2O - 6e- = 6H+ + O3

[0085] Ozone water is generated in the atomization area 221 through electrolysis. The ozone water is atomized by the atomization module 250 to form a water mist with a sterilization and disinfection function, and the water mist is ejected outward from the aerosol spray outlet 121 to sterilize, disinfect, remove odors, etc. the toilet seat board 520, the toilet bowl 530, etc.

[0086] In some embodiments, referring to Figure 2 and Figure 3 , the sterilization and odor removal device main body 100 includes a top shell 103, a middle shell 104, and a bottom shell 105. The top shell 103, the middle shell 104, and the bottom shell 105 are combined to form the sterilization and odor removal device main body 100, and a cavity 110 and a control chamber 150 are formed inside the sterilization and odor removal device main body 100, which is convenient for processing and the installation of each component.

[0087] In another embodiment of the present invention, a sterilization and odor removal device is further provided, which is applied to scenarios such as shoe cabinets, storage cabinets, and wash cabinets, and is used to spray a water mist with a disinfection effect during operation for sterilization, disinfection, cleaning, etc.

[0088] Referring to Figure 1 and Figure 2, the sterilization and deodorization device includes a sterilization and deodorization device main body 100, an electrolysis module 260, an atomization module 250, and a control circuit board 300.

[0089] Among them, referring to Figure 1 and Figure 2 , a cavity 110, a control chamber 150, and atomization holes 223 are provided in the sterilization and deodorization device main body 100. The cavity 110 is used to hold brine, clean water, or a mixture of water and other substances.

[0090] Among them, referring to Figure 1 and Figure 2 , the electrolysis module 260 can contact the solution in the cavity 110 to electrolyze the liquid to form electrolyzed water. Preferably, the electrolysis module 260 is provided in the cavity 110, and the electrolysis module 260 is used to electrolyze the liquid in the cavity 110 to form electrolyzed water.

[0091] Among them, referring to Figure 1 and Figure 2 , the atomization holes 223 communicate with the cavity 110, and the atomization module 250 is provided in the atomization holes 223 to atomize the electrolyzed water to form an aerosol. An aerosol spray outlet 121 communicating with the atomization holes 223 is provided on the outer wall of the sterilization and deodorization device main body 100.

[0092] Furthermore, the sterilization device main body 100 is provided with an identification module (not shown in the figure). The identification module is electrically connected to the control circuit board to turn on or off 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.

[0093] For example: The identification module can be an infrared sensor. When the user closes the cabinet door, when the identification module senses that the cabinet door is closed, the atomization module 250 and the electrolysis module 260 are turned on, 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 turned off.

[0094] For example: The identification module can be a photosensitive sensor. When the cabinet door is closed, when the photosensitive sensor senses that the light inside the cabinet becomes dim, the atomization module 250 and the electrolysis module 260 are turned on, 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 turned off. Or, when the instant electrolysis type spray disinfection device is placed in a relatively dark place, then the door is opened or the light is turned on, indicating that someone has entered, and the photosensitive sensor senses that the light becomes bright, and the atomization module 250 and the electrolysis module 260 are turned on.

[0095] For example, the recognition module can be an image sensor. For example, when the image sensor senses that the cabinet door is closed, the atomization module 250 and the electrolysis module 260 are activated for spray disinfection. Conversely, when the image sensor senses that the cabinet door is open, the atomization module 250 and the electrolysis module 260 are not activated or are deactivated.

[0096] 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.

[0097] 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: an 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, this coating is not permanent. If the coating on the surface of the electrode plate 261 ages or peels 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, by using the power detection module to detect the power of the electrolysis module 260, when the electrolysis power abnormally decreases, the user is alarmed to replace or repair the accessories, 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.

[0098] Among them, with reference 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 is formed and mature 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 of the present utility model will not be elaborated here.

[0099] The rest of this embodiment is the same as that of Embodiment 1. For the features not explained in this embodiment, the explanations of Embodiment 1 are adopted and will not be elaborated here.

[0100] 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 all be regarded as belonging to the scope of patent protection determined by the claims submitted for the present utility model.
