[0032] Figures 1 to 3 The disinfection module 100 of an embodiment of the present utility model is shown. The disinfection module 100 includes a housing 101, a fan 116, a first disinfection device, and a second disinfection device. The housing 101 includes an air duct 118. The air duct 118 includes an air inlet 102 and an air outlet 103, and both the air inlet 102 and the air outlet 103 are located on the outer surface of the housing 101. The fan 116 is used to drive air to flow along the air duct 118, and the second disinfection device is arranged in the air duct 118. The specific structures of the first disinfection device and the second disinfection device will be specifically introduced below.

[0033] The disinfection module 100 has a first disinfection mode and a second disinfection mode, and these two disinfection modes do not operate simultaneously. In Figure 3 the figure, the dotted line with an arrow indicates the main flow path of air when the fan 116 is operating. Whether the disinfection module 100 is in the first disinfection mode or the second disinfection mode, the path of the air flow flowing through the air duct 118 is basically the same. However, when the disinfection module 100 is in different disinfection modes, the operating states of the first disinfection device and the second disinfection device are different. When the disinfection module 100 is in the first disinfection mode, the second disinfection device is closed, and the first disinfection device sprays the disinfectant into the air duct 118, and the fan 116 blows the disinfectant out from the air outlet 103. When the disinfection module 100 is in the second disinfection mode, the first disinfection device is closed, and the fan 116 blows the disinfection particles out from the air outlet 103. The disinfectant can be a hypochlorous acid solution. When the second disinfection device ionizes air, it can ionize oxygen and / or water vapor in the air, and the disinfection particles can include ions (such as negative oxygen ions, hydrogen ions, hydroxide ions, etc.) and groups (such as hydroxyl groups).

[0034] That is, in the first disinfection mode, the disinfection module 100 mainly disinfects the surrounding environment of the disinfection module 100 by spraying disinfectant liquid; in the second disinfection mode, the disinfection module 100 mainly disinfects the surrounding environment of the disinfection module 100 by spraying disinfection particles. The disinfection module 100 of the present utility model has two different disinfection modes and can disinfect the environment with different types of disinfection substances. Compared with the disinfection module 100 that only uses disinfectant liquid for disinfection in the prior art, the disinfection module 100 of the present utility model can be applied to more scenarios. In addition, for the disinfection module 100 of the present utility model, the air ducts 118 and the fans 116 of the two disinfection modes are shared, and the air flow paths when blowing out the disinfectant liquid and when blowing out the disinfection particles are basically the same. The disinfection module 100 does not need to set up a dedicated air duct 118 for the disinfectant liquid and the disinfection particles respectively, and the disinfection module 100 does not need to set up a dedicated fan 116 for the disinfectant liquid and the disinfection particles respectively. Therefore, the structure of the disinfection module 100 is relatively simple, and the manufacturing difficulty and cost are relatively low.

[0035] In some embodiments, the first disinfection device includes an electrolyzer 109 and a spraying unit 114. The first disinfection device has both the function of generating disinfectant liquid and the function of spraying disinfectant liquid. Please refer to Figure 1 and Figure 2 . In this embodiment, the housing 101 includes an outer frame 117, a water tank 111 and an upper cover 108. As Figure 3 shown, the housing 101 further includes a liquid storage cavity 110. The liquid storage cavity 110 is arranged in the water tank 111. The water tank 111 is accommodated inside the outer frame 117. The upper cover 108 is detachably installed on the top of the outer frame 117, and the upper cover 108 covers the liquid storage cavity 110 of the water tank 111. The liquid storage cavity 110 is used to accommodate the liquid to be electrolyzed 119. If the disinfectant liquid is hypochlorous acid solution, the liquid to be electrolyzed 119 contains chlorine element. For example, in order to save costs, the liquid to be electrolyzed 119 can be sodium chloride aqueous solution (i.e., brine) or tap water. As Figure 3 shown, the inner surfaces of the water tank 111 and the outer frame 117 jointly enclose an air duct 118. The air inlet 102 and the air outlet 103 are both arranged on the outer surface of the outer frame 117. The electrolyzer 109 is arranged in the liquid storage cavity 110. The electrolyzer 109 includes electrode plates (the electrode plates are not shown). The electrode plates can contact the liquid to be electrolyzed 119 in the liquid storage cavity 110. After the electrode plates are energized, the electrolyzer 109 will electrolyze the liquid to be electrolyzed 119. As Figure 3As shown, the spraying unit 114 is connected to the housing 101. For example, the spraying unit 114 is fixed to the water tank 111 by screws. The spraying unit 114 includes a spraying inlet 120 and a spraying outlet 121. The spraying inlet 120 communicates with the liquid storage chamber 110, and the spraying outlet 121 communicates with the air duct 118. The spraying outlet 121 is used to spray the disinfectant liquid into the air duct 118. When the disinfection module is in the first disinfection mode, the electrolyzer 109 electrolyzes the liquid to be electrolyzed 119 to generate a disinfectant liquid in the liquid storage chamber, and the spraying unit 114 sprays the disinfectant liquid into the air duct 118.

[0036] The second disinfection device includes an ion generator 115. The ion generator 115 is arranged in the air duct 118 and can be used to ionize the water vapor in the air duct 118 to generate hydrogen ions and hydroxyl radicals. Among them, the "water vapor in the air duct 118" specifically refers to the water vapor contained in the air in the air duct 118. The ion generator 115 also has electrodes (not shown), which are located in the air duct 118 and can contact the water vapor in the air duct 118. After the electrodes are energized, the ion generator 115 will ionize the water vapor. The fan 116 is used to drive the air to flow along the air duct 118, that is, the fan 116 can drive the air to enter the air duct 118 from the air inlet 102 and drive the air to leave the air duct 118 from the air outlet 103. The fan 116 can be installed in the air duct 118. The fan 116 is located at the bottom of the water tank 111, and the fan 116 is connected to the water tank 111 or the outer frame 117 by screws.

[0037] As Figure 2 shown, the disinfection module 100 further includes a circuit board 112 and a cover plate 113. The circuit board 112 is connected to the water tank 111 and is located outside the liquid storage chamber 110. The cover plate 113 is connected to the water tank 111 by screws, and the cover plate 113 covers the circuit board 112. The circuit board 112 includes a controller (not specifically shown), which is used to control the operation of the fan 116, the electrolyzer 109, the ion generator 115 and the spraying unit 114.

[0038] When the disinfection module 100 is in the first disinfection mode, the electrolyzer 109 electrolyzes the liquid to be electrolyzed 119 to generate a hypochlorous acid solution in the liquid storage chamber 110. The spraying unit 114 sprays the hypochlorous acid solution into the air duct 118, and the ion generator 115 is turned off and does not ionize the water vapor in the air duct 118; the hypochlorous acid solution sprayed into the air duct 118 will be mixed into the air flow formed by the fan 116 (for example, this air flow will carry hypochlorous acid droplets), and the fan 116 will blow out the hypochlorous acid solution from the air outlet 103. Taking brine as an example, the chemical formula for generating a hypochlorous acid solution by electrolyzing the liquid to be electrolyzed 119 is as follows:

[0039]

[0040] Cl 2 + H 2 O = HCl + HClO.

[0041] When the disinfection module 100 is in the second disinfection mode, the electrolyzer 109 and the spraying unit 114 are turned off. The electrolyzer 109 does not perform electrolysis, and the spraying unit 114 does not spray the hypochlorous acid solution or the liquid to be electrolyzed 119 into the air duct 118. The ion generator 115 ionizes the water vapor in the air duct 118 to generate hydrogen ions and hydroxyl radicals, and the fan 116 blows the hydrogen ions and hydroxyl radicals out from the air outlet 103.

[0042] That is, in the first disinfection mode, the disinfection module 100 mainly disinfects the surrounding environment of the disinfection module 100 by spraying hypochlorous acid. In the second disinfection mode, the disinfection module 100 mainly disinfects the surrounding environment of the disinfection module 100 by spraying hydroxyl radicals. The first disinfection mode can be applied to scenarios where bacteria are likely to grow and a strong disinfection effect is required, such as bathrooms and toilets when there is no one. The second disinfection mode can be applied to scenarios where people stay for a long time to prevent discomfort caused by hypochlorous acid to the human body. If there are items in the environment where the disinfection module 100 is located that may be easily corroded by hypochlorous acid, then the user can also make the disinfection module 100 operate in the second disinfection mode. Therefore, the disinfection module 100 of the present utility model has two different disinfection modes and can disinfect the environment with different disinfection substances. Compared with the disinfection module that only uses hypochlorous acid for disinfection in the prior art, the disinfection module 100 of the present utility model can be applied to more scenarios.

[0043] In some embodiments, the spraying unit 114 may be configured as an atomizer. When the disinfection module 100 is in the first disinfection mode, the spraying unit 114 atomizes the disinfectant liquid (such as hypochlorous acid solution) and sprays the atomized disinfectant liquid into the air duct 118. More specifically, in some embodiments, the atomizer may be configured as an ultrasonic atomizer, which has an ultrasonic atomization sheet. One side surface of the ultrasonic atomization sheet contacts the liquid to be electrolyzed 119, and the other side surface of the ultrasonic atomization sheet faces the spraying outlet 121. The atomization sheet uses high-frequency oscillation to break up the liquid so as to atomize the liquid. In other embodiments not shown, in order to spray the disinfectant liquid into the air duct 118, the spraying unit 114 may also include a pump and a nozzle. The pump transports the hypochlorous acid solution to the nozzle, and the nozzle sprays the hypochlorous acid solution into the air duct 118. When the spraying unit 114 is configured as an atomizer, the hypochlorous acid solution sprayed by the spraying unit 114 is in a mist form. The mist-form hypochlorous acid solution can be more fully dispersed into the air flow generated by the blower 116, and hypochlorous acid is also more likely to diffuse in the environment where the disinfection module 100 is located. In addition, in order to reduce the cost of the disinfection module 100, in other embodiments not shown, the first disinfection device may also omit the function of generating the disinfectant liquid. The first disinfection device may only include the spraying unit 114 and not include the electrolyzer 109, and the liquid storage chamber 110 directly stores the disinfectant liquid.

[0044] In some embodiments, the electrolyzer 109 may be installed on the bottom wall 124 of the liquid storage chamber 110. In this way, even if the liquid to be electrolyzed 119 in the liquid storage chamber 110 is less, the electrolyzer 109 can still contact the liquid to be electrolyzed 119 in the liquid storage chamber 110. The liquid level of the liquid to be electrolyzed 119 does not need to be kept at a relatively high position all the time, and the user does not need to frequently replenish the liquid to be electrolyzed 119 into the liquid storage chamber 110.

[0045] In other embodiments, as Figure 4 shown, the housing 101 further includes a mounting groove 125. The mounting groove 125 is provided at the water tank 111. The mounting groove 125 includes an opening 126. The opening 126 is located at the top of the mounting groove 125 and the opening 126 is located on the bottom wall 124 of the liquid storage chamber 110. The electrolyzer 109 is disposed in the mounting groove 125. In this setting manner, even if the liquid to be electrolyzed 119 in the liquid storage chamber 110 is less, the electrolyzer 109 can still contact the liquid to be electrolyzed 119 in the liquid storage chamber 110. Moreover, the mounting groove 125 can position the electrolyzer 109, facilitating the installation of the electrolyzer 109.

[0046] In some embodiments, the blower 116 may be configured as a centrifugal blower 116, as Figure 3As shown, the blower 116 includes a blower housing 122, an impeller 123, and a motor (the motor is not shown). The blower housing 122 is connected to the water tank 111 or the outer frame 117. The impeller 123 is located inside the blower housing 122, and the motor drives the impeller 123 to rotate, thereby forming an air flow.

[0047] Please refer to Figure 1 and Figure 2 , in some embodiments, the outer surface of the housing 101 includes a bottom surface 106, a top surface 107, and a plurality of side surfaces 104. The top ends of the side surfaces 104 are connected to the top surface 107, and the bottom ends of the side surfaces 104 are connected to the bottom surface 106. For Figure 1 and Figure 2 the disinfection module 100 shown, its housing 101 is in the shape of a cuboid. The housing 101 includes 4 side surfaces 104, and these four side surfaces 104 are respectively a front side surface 105, a rear side surface, a right side surface, and a left side surface. The air inlet 102 is provided on the bottom surface 106, and at least one side surface 104 is provided with an air outlet 103. In Figure 1 the embodiment shown, in order to simplify the structure of the air duct 118, only the front side surface 105 among the four side surfaces 104 of the housing 101 is provided with the air outlet 103. However, in other embodiments, the air outlet 103 can also be added to the remaining side surfaces 104 to expand the disinfection range of the disinfection module 100. Since the air inlet 102 is provided on the bottom surface 106 and the air outlet 103 is provided on the side surface 104, the disinfection module 100 is suitable for being installed at the bottom of an object, and this object can be a cabinet, a bracket, etc. When the disinfection module 100 is installed at the bottom of the object, its top surface 107 is connected to the object, and the air inlet 102 and the air outlet 103 are not easily blocked by the object, and the air flow can normally enter and exit the air duct 118. Moreover, in the case where the spraying outlet 121 faces the horizontal direction and the ion generator 115 is located below the spraying unit 114, setting the air outlet 103 on the side surface 104 is beneficial to shortening the flow path of the air flow (compared with the case where the air outlet 103 is located on the top surface 107 of the housing 101), and improving the efficiency of blowing the disinfectant liquid and disinfection particles out of the air outlet 103.

[0048] As Figure 3 shown, in some embodiments, in order for the disinfectant liquid to be ejected from the air outlet 103, the spraying outlet 121 and the air outlet 103 can be arranged facing each other, and the axes of the spraying outlet 121 and the air outlet 103 coincide. The axes of both are straight line L.

[0049] In some embodiments, to facilitate the ejection of the disinfectant solution and disinfection particles from the air outlet 103 and to facilitate the diffusion of the disinfectant solution and disinfection particles in the environment, the air outlet 103 can be configured such that the cross-sectional area of the air outlet 103 gradually increases from the end of the air outlet 103 close to the spraying outlet 121 to the end of the air outlet 103 far from the spraying outlet 121. The cross-sectional area of the air outlet 103 refers to the area of the portion of the air outlet 103 on a plane that is perpendicular to the axis (straight line L) of the air outlet 103 and cuts through the air outlet 103. As Figure 3 shown, to meet the above conditions, the air outlet 103 can be in a flared shape. The end of the air outlet 103 close to the spraying outlet 121 is the rear end of the air outlet 103, and the end of the air outlet 103 far from the spraying outlet 121 is the front end of the air outlet 103. From the rear end of the air outlet 103 to the front end of the air outlet 103, the diameter of the air outlet 103 gradually increases.

[0050] As Figure 3 shown, in some embodiments, the blower 116 is located in the air duct 118. The blower 116 is located upstream of the ion generator 115 and is also located upstream of the spraying outlet 121. The blower 116 being located upstream of the ion generator 115 means that the airflow in the air duct 118 first passes through the blower 116 and then through the ion generator 115. Similarly, the blower 116 being located upstream of the spraying outlet 121 means that the airflow in the air duct 118 first passes through the blower 116 and then through the spraying outlet 121. The blower 116 being located upstream of the ion generator 115 and the spraying outlet 121 can prevent the blower 116 from consuming the hydroxyl and hypochlorous acid solution used for disinfecting the external environment. In addition, the droplets of the hypochlorous acid solution may cause the motor of the blower 116 to short-circuit and may also overlook the impeller 123 and motor of the blower 116, thereby affecting the lifespan of the motor. Therefore, the blower 116 being located upstream of the spraying outlet 121 can also reduce the contact between the hypochlorous acid solution and the motor and reduce the adverse effects of the hypochlorous acid solution on the motor.

[0051] In some embodiments, the spraying outlet 121 and the ion generator 115 are offset from each other. This arrangement can reduce the hypochlorous acid droplets sprayed onto the surface of the ion generator 115, thereby reducing the interference of the hypochlorous acid droplets on the ion generator 115. Herein, "the spraying outlet 121 and the ion generator 115 are offset from each other" means that in the axial direction of the spraying outlet 121, there is no overlapping portion between the spraying outlet 121 and the ion generator 115. To offset the spraying outlet 121 and the ion generator 115 from each other, the positions of the spraying unit 114 and the ion generator 115 can be set in the form shown as Figure 3 shown. As Figure 3As shown, the ion generator 115 is located upstream of the spraying unit 114 (the air flow passes through the ion generator 115 first and then through the spraying unit 114), the spraying unit 114 is located above the ion generator 115, and the spraying outlet 121 of the spraying unit 114 is arranged forward.

[0052] As Figure 5 As shown, the present utility model further provides a bathroom cabinet 200, which includes a cabinet body 201 and the disinfection module 100 in any of the above embodiments. The disinfection module 100 is connected to the cabinet body 201, and both the air inlet 102 and the air outlet 103 are exposed outside the cabinet body 201 so that the hypochlorous acid solution and hydroxyl radicals can be blown into the bathroom. The bathroom cabinet 200 integrates the disinfection module 100, and the bathroom cabinet 200 can not only store toiletries but also disinfect the bathroom environment.

[0053] As Figure 5 As shown, in some embodiments, the disinfection module 100 is detachably connected to the bottom of the cabinet body 201. The disinfection module 100 can be connected to the bottom of the cabinet body 201 by screws, or the disinfection module 100 and the cabinet body 201 can also be connected by a snap connection. Based on the common installation height of the bathroom cabinet 200, the disinfection module 100 being located at the bottom of the cabinet body 201 makes the height of the disinfection module 100 appropriate, facilitating the user to use and repair the disinfection module 100. In addition, the cabinet body 201 of the bathroom cabinet 200 is usually installed above the washbasin, and the washbasin is prone to water accumulation and dirt accumulation. Therefore, the disinfection module 100 being located at the bottom of the cabinet body 201 also makes the disinfection module 100 suitable for disinfecting the area around the washbasin.

[0054] In some embodiments, the bathroom cabinet 200 further includes a cabinet door 202, and the cabinet door 202 is movably connected to the cabinet body 201. For example, the cabinet door 202 is connected to the cabinet body 201 by hinges. The cabinet door 202 and the cabinet body 201 jointly define a storage chamber, which is not shown in the drawings. Figure 5 In the figure, the cabinet door 202 blocks the storage chamber, and the storage chamber is located behind the cabinet door 202. The storage chamber can be used to store toiletries. In some embodiments, the bathroom cabinet 200 can be set as a mirror cabinet, that is, the cabinet door 202 includes a door frame and a lens installed on the door frame.

[0055] As Figure 5As shown, in some embodiments, a button assembly 203 is provided on the surface of the cabinet door 202 facing away from the storage chamber. The button assembly 203 is communicatively connected to the disinfection module 100. The button assembly 203 and the circuit board 112 of the disinfection module 100 can communicate through wires, or can communicate through Bluetooth or other wireless transmission methods. The button assembly 203 is used to switch the operating state of the disinfection module 100. The user can manually control the disinfection module 100 through the button assembly 203. Switching the operating state of the disinfection module 100 can be turning on the disinfection module 100, turning off the disinfection module 100, changing the disinfection mode, etc. The button assembly 203 can include multiple buttons. For example, one button is used to turn on and off the disinfection module 100, and another button is used to change the disinfection mode. To improve the aesthetics of the bathroom cabinet 200, the button assembly 203 can be set as a capacitive touch button assembly 203.

[0056] The disinfection module 100 can be manually controlled by the user so as to operate according to the disinfection mode selected by the user. In some embodiments, the disinfection module 100 also has the function of automatically selecting the disinfection mode according to the environmental conditions, and the intelligence level of the disinfection module 100 is relatively high.

[0057] Specifically, the bathroom cabinet 200 further includes a sensor. The sensor is installed on the cabinet body 201 or on the disinfection module 100. The sensor is communicatively connected to the disinfection module 100. At least a part of the detection area of the sensor is located in front of the disinfection module 100. Among them, the air outlet 103 is arranged forward, and the orientation of the air outlet 103 is "front". The sensor can be an infrared sensor. The detection area is not shown in the drawings. The detection area of the sensor is generally fan-shaped or conical. The sensor can be arranged forward or forward and downward. The sensor can be installed on the cabinet door 202 or on the front side 105 of the housing 101 of the disinfection module 100. When the sensor detects that someone is in the detection area, the disinfection module 100 operates in the second disinfection mode, that is, disinfects through hydroxyl radicals. When the sensor detects that no one is in the detection area, the disinfection module 100 operates in the first disinfection mode, that is, disinfects through hypochlorous acid solution. When someone is in the detection area, to reduce the impact of hypochlorous acid on the human body, the disinfection module 100 disinfects through hydroxyl radicals; when no one is in the detection area, the disinfection module 100 uses hypochlorous acid with stronger disinfection ability for disinfection, so as to perform relatively strong disinfection on the environment where the disinfection module 100 is located.
