[0030] In order to clearly and completely describe the technical solution of the present application, further explanation will be given below in conjunction with embodiments and drawings.

[0031] The applicant has previously developed an air disinfection device that can not only perform open work, but also perform closed work. When the device is in closed work, it can form a directional cold spray ion wind. For example, when the user touches the metal bar and the device performs closed work, the cold spray ion wind can be blown to the user in a directional manner to increase the local concentration of negative oxygen ions around the user, improve the local disinfection effect and the user's ability to ingest negative oxygen ions. The air disinfection device does not include components such as fans. The directional cold spray ion wind is mainly formed by the electric field between the human body and the carbon brush during closed work, so it is weaker than the wind formed by fans, etc., and users need to feel it carefully. On this basis, the embodiment of the present application introduces a visualization component in the air disinfection device so that the user can visually and intuitively understand the situation of the device directional release of negative ions. For example, when the user picks up the air disinfection device with his hand and faces himself, and his hand touches the metal bar on the device housing, the user can directly observe the visualization component while feeling the directional cold spray ion wind on the skin, thereby obtaining more intuitive feedback and improving the user experience.

[0032] See also Figures 1 to 6 An embodiment of the present application provides an air disinfection device, including a shell 100, a main control unit, an ion generating component 300 and a visualization component 500.

[0033] The shell is the main supporting structure of the air disinfection equipment and is mainly used to form a storage space. The shape of the shell can be any possible shape such as a cylinder, a cuboid, a specific object shape, etc., and this application does not limit this. For example, Figure 2 As shown, the housing is in a rectangular parallelepiped shape, including an upper housing 110 and a lower housing 120, and the sides of the two are connected together, for example, they can be welded together by ultrasonic welding or other processes, and a receiving space 101 is formed between the upper housing 110 and the lower housing 120. The specific shape and size of the receiving space can vary depending on the housing situation. Possible components, such as ion generating components, large resistors, main control units, batteries, sensors, etc., can be arranged in the receiving space.

[0034] The shell is made of non-metallic materials, such as plastic, ceramic, rubber, glass, etc. It is understandable that when the shell includes multiple different components, these components can be made of the same or different materials, and the present application does not limit this. For example, when the shell includes components such as side walls, an upper cover plate, and a lower cover plate, the side walls can be made of plastic or ceramic materials, and the upper cover plate and the lower cover plate can be made of plastic or glass materials. For another example, when the shell includes components such as Figure 2When the upper shell 110 and the lower shell 120 are shown, the upper shell 110 and the lower shell 120 can both be made of plastic or different materials. It can also be understood that in some cases, metal parts may be partially arranged, installed or embedded on the shell, and the present application does not limit this, as long as it does not affect the normal operation of the air disinfection equipment and the generation of the cold spray ion wind.

[0035] A metal strip is provided on the outer surface of the housing, such as the side surface, and at least a portion of the metal strip is exposed to the environment and can be touched by the user. The present application does not limit the specific shape and quantity of the metal strip, which can be elliptical, square, waist-shaped, irregular, etc., and is not required to be strip-shaped, as long as it can provide a certain contact surface for the user to touch. For example, Figure 1 and Figure 2 As shown, a metal strip 401 can be provided on both sides of the housing 100, and waist-shaped holes are provided on both sides of the housing. The metal strip 401 is adaptively embedded in the waist-shaped holes, and the outer surface is exposed to the environment and is flush or substantially flush with the outer surface of the housing. When the user holds the air disinfection device, these metal strips can be contacted more naturally. As another example, the metal strip can also be arranged on the first surface 111 of the upper shell of the housing, the second surface of the lower shell, or other positions that are convenient for the user to contact.

[0036] See also Figure 2 and Figure 6 , a large resistor 402 is provided in the accommodating space 101. A large resistor is also often referred to as a large resistance resistor, a high resistance resistor, etc. The large resistor in the embodiment of the present application mainly refers to a resistor whose resistance value reaches above the kilo-ohm level. Exemplarily, the resistance value of the large resistor can reach the megohm level or higher, so that the current passing through the large resistor during operation of the air disinfection device does not exceed the micro-ampere level, so as to meet higher requirements of product standards, such as medical electrical equipment standards. It is understandable that the large resistor in the embodiment of the present application may refer to a single resistor, or it may be a component composed of multiple resistors and other possible electronic components, and the present application is not limited to this, as long as its resistance value can reach at least above the kilo-ohm level.

[0037] One end of large resistor 402 is electrically connected to metal strip 401, and the other end is grounded. In this way, a path is formed from metal strip, large resistor to ground terminal, for ease of distinction, referred to as first path in the embodiment of the present application. In some implementations, digital ground can be provided on the circuit board (such as main control board) in the air disinfection equipment, and the other end of large resistor can be directly or indirectly connected with the digital ground. Of course, in other implementations, the other end of large resistor can also be connected with signal ground etc.

[0038] A main control unit is also provided in the accommodation space 101. A control unit generally refers to a unit that can issue various control instructions to control the operation of various components connected thereto to realize certain specific functions. In the scheme of the present application, the control unit is used as the main controller of the air disinfection device, and is therefore referred to as the main control unit. The main control unit can be implemented using existing hardware and known computer programs. Of course, in some cases, the main control unit can also be implemented using other possible methods, such as improved hardware and improved methods. Exemplarily, a microcontroller unit MCU or the like can be used as the main control unit of the air disinfection device.

[0039] Optionally, the main control unit, the large resistor, etc. can be arranged on the main control board, and the connection line between the large resistor and the metal strip, and the connection line between the large resistor and the main control unit can also be arranged on the main control board. Compared with the previously designed method of forming the first path together through elastic parts, connectors, etc., the structure of this method is simpler, the electrical characteristics are relatively reliable, and the cost is relatively low.

[0040] The ion generating component is mainly used to generate and release electrons. The life span of electrons is extremely short (nanosecond level), and they cannot exist in the air for a long time. Moreover, their affinity to oxygen is much greater than that of other gases in the air such as N2, and the CO2 content in the air is much lower than that of O2. Therefore, most of the electrons generated by ionization are captured by oxygen to form negative oxygen ions, which are transported to the ambient space. The ion generating component in this embodiment can adopt an existing ion generator, or other possible structures can be adopted. It can be understood that the ion generating component is usually directly or indirectly grounded.

[0041] The ion generating component can be electrically connected to the main control unit, and the main control unit can output a control signal to it to control it to generate and release electrons.

[0042] In some possible implementations, see Figure 2 and Figure 3 , an opening is provided on the first surface 111 of the housing 100 to form a mounting groove (hereinafter referred to as the first mounting groove 104 for easy distinction). The ion generating component 300 may include a carbon brush 301, which is installed in the first mounting groove 104 through a carbon brush plate 302, with its bottom connected to the carbon brush plate 302 and its top facing the environment outside the housing. The ion generating component 300 can raise the low voltage to obtain the required DC negative high voltage, and negative corona discharge occurs under the action of the DC negative high voltage, and the air is continuously ionized to form a large number of positive and negative ion pairs. The positive ions move to the bottom of the carbon brush due to the action of the negative high voltage and are finally neutralized, while a large number of electrons are quickly released into the air through the top of the carbon brush.

[0043] The air disinfection device can work in an open mode and a closed mode. These two working modes can be realized correspondingly when the conductive medium in the environment such as the user does not contact the metal strip and contacts the metal strip. When in an open working mode, a large number of electrons are released into the air through the top of the carbon brush and captured by oxygen to form negative oxygen ions. The negative oxygen ions are repelled away from the top of the carbon brush by the negative high-voltage electric field, thereby forming a negative ion wind. This open structure uses the carbon brush as the negative electrode and the entire space where the air disinfection device is located (such as the earth, desktop, etc. in the environment) as the positive electrode, so that a high-voltage electrostatic field will be formed between the positive and negative electrodes, so that the entire space will be filled with an electrostatic field, which will greatly improve the effect of the diffusion of negative oxygen ions to the surrounding space, has good diffusivity and high ion concentration, and is suitable for providing good disinfection capabilities for indoor spaces. When the user's body parts are in contact with the metal strip, for example, when the user holds the air disinfection device, the air disinfection device is in a closed working mode. Under the action of negative high voltage, the top of the carbon brush also quickly releases electrons into the air and forms negative oxygen ions. The difference is that since the user's body parts are in contact with the metal strip, the metal strip is grounded through a large resistor. At this time, the user's body is at a high potential relative to the carbon brush (negative high voltage), forming a closed electrode between the carbon brush and the human body, forming a strong electric field, so that the negative oxygen ions near the carbon brush are transported more to the direction of the user's area (such as the area where the head and face are located) under the action of the electric field, forming a directional cold spray negative ion wind facing the user, which can locally increase the concentration of negative oxygen ions in the area where the human body is located and improve the local disinfection effect. At the same time, since the cold spray negative ion wind blows towards the human body in a directional manner, it can also improve the human body's ability to inhale negative oxygen ions through the respiratory tract, thereby enhancing cardiovascular and cerebrovascular functions, etc., and improving human body functions. In addition, due to the presence of a large resistor, the field strength between the carbon brush and the human body will not be too high, so too much ozone will not be generated in a closed working mode, which can effectively avoid ozone exceeding the standard.

[0044] Alternatively, see Figure 2 The ion generating part 300 may further include a first protective cover 303, which is semi-enclosed and disposed on the outer periphery of the carbon brush plate 302 to isolate the carbon brush plate 302 from some components (such as a high voltage generating circuit, etc.) in the accommodating space.

[0045] Visual components mainly refer to components that can be visually observed by users. They can display the directional release of electrons by the ion generating components through different visual effects, such as whether the ion generating components are currently releasing electrons in a directional manner to a specific conductive medium in the environment such as the user, that is, whether they are in a closed working mode. In addition to displaying information about whether or not, in some possible implementations, the visual components can also display the number and magnitude of directional release of electrons, the strength of the negative ion wind formed, and other conditions.

[0046] The visualization component can be electrically connected to the main control unit, and the main control unit can output a control signal to it to control its display.

[0047] In some implementations, the visualization component may include a light source, and the light source may be disposed above or below the outer surface of the housing, or at other locations, as long as light can be observed by a user from outside the housing when the light source is turned on.

[0048] In some other implementations, see Figures 1 to 4 The visualization component 500 may include a light source 502 and a light guide bar 501. The light source 502 is disposed in the accommodating space 101 and is electrically connected to the main control unit. Exemplarily, the light source 502 may be in the form of LED lamp beads or the like, which may be integrated on the main control board 200. The light guide bar 501 is disposed on the outer surface of the housing 100 to guide the light emitted by the light source 502 to the outer surface of the housing 100, thereby obtaining a softer and more uniform visual effect for the user to observe. The light source introduction end 5011 of the light guide bar 501 may be close to the light source 502, thereby guiding as much light as possible to the outer surface of the housing.

[0049] Alternatively, see Figure 3 The light guide bar 501 can be arranged on the first surface 111 of the housing 100, that is, the surface with the first mounting groove 104. In this way, when the user picks up the air disinfection device and puts it into closed operation, the top of the light guide bar 501 and the carbon brush 301 are facing the user, so that the user can feel the cold spray ion wind and visually observe the lighting effect at the same time.

[0050] Optionally, the light guide strip may be in a variety of possible shapes such as a line, an arc, or a ring, which is not limited in the present application. Figure 2 and Figure 3 The main body of the light guide bar 501 is annular and arranged around the outer periphery of the carbon brush. In another exemplary embodiment, the light guide bar can also be linear and arranged at a certain position between the carbon brush 301 and the button 600 on the surface of the housing.

[0051] Alternatively, see Figure 3 and Figure 4 A receiving groove 103 is formed on the housing 100, and the light guide bar 501 is embedded in the receiving groove 103, so that the light guide bar 501 is slightly lower than the housing surface or basically flush with it.

[0052] Optionally, a decorative plate that can cover the light guide strip and is at least partially made of a light-transmitting material can be provided on the surface of the housing. The decorative plate can be partially or completely made of glass, acrylic, plastic or other materials, and can be made using existing processes such as in-film injection molding. The present application does not limit its specific materials and preparation processes. For example, Figure 7As shown, the decorative panel 130 may have a local light-transmitting area 1301, and the light emitted or conducted by the light source and / or light guide strip disposed below the decorative panel 130 can pass through the light-transmitting area 1301 and be observed by the user. The decorative panel can be connected to the shell by means of snaps, pasting, etc., and the specific connection method between the two is not limited in this application. In this way, on the one hand, the display effect of the visualization component is slightly or basically not affected, and on the other hand, it can also protect the components covered by it, including the light guide strip. For example, see Figures 2 to 4 A decorative plate 130 is disposed on the first surface 111 of the housing 100 , and a first opening 107 corresponding to the first mounting groove 104 on the first surface 111 is opened on the decorative plate 130 to facilitate the release of negative oxygen ions.

[0053] It is understandable that the visualization component may also include other possible components, which is not limited in this application.

[0054] When the air disinfection equipment is in a closed operation, the main control unit can output a control signal (hereinafter referred to as the first control signal for the sake of distinction) to control the light source to be turned on; when it is not in a closed operation, for example, in an open operation, the main control unit outputs another control signal (hereinafter referred to as the second control signal for the sake of distinction) to control the light source to be turned off. In this way, whether the ion generating component is releasing electrons in a direction is displayed. Exemplarily, the first control signal can be a high level, and the second control signal can be a low level; and again exemplarily, the first control signal and the second control signal can be two different combinations of a high level and a low level, respectively.

[0055] Optionally, the air disinfection device may further include a touch sensing circuit, which is electrically connected to the main control unit and is used to sense whether a biological being touches the metal strip, and input the sensed signal (hereinafter referred to as the second signal for ease of distinction) to the main control unit. For example, when the user touches the metal strip, the touch sensing circuit outputs a high level to the main control unit, and when the user does not touch the metal strip, the touch sensing circuit outputs a low level to the main control unit.

[0056] The touch sensing circuit may adopt an existing circuit or other possible implementation methods. For example, see Figure 5 and Figure 6, the touch sensing circuit may include a copper-clad layer 221 and a second sampling circuit (not shown in the figure) located in the accommodating space. The copper-clad layer 221 is arranged corresponding to the metal strip 401, and the two are equivalent to forming a capacitor. The copper-clad layer is electrically connected to the second sampling circuit, and the second sampling circuit is electrically connected to the main control unit to transmit the sampled signal. For example, when a user touches the metal strip, the capacitance value of the capacitor is changed due to the high potential of the user's body, so that the signal sampled by the second sampling circuit changes, and the main control unit can judge that a user has touched the metal strip at this time, and then output a first control signal to control the visualization component. It can be understood that the second sampling circuit can adopt an existing sampling circuit.

[0057] Alternatively, see Figure 6 A second barrier 142 is provided between the corresponding metal strip 401 and the copper clad layer 221 so that the electrical gap formed between the metal strip 401 and the copper clad layer 221 exceeds a preset safety value.

[0058] Electrical clearance generally refers to the shortest spatial distance measured between two conductive parts or between a conductive part and the protective interface of the equipment. The preset safety value can be the shortest distance that can be insulated through air while ensuring stable and safe electrical performance, or any value greater than the shortest distance. For example, it can be 2 cm.

[0059] The air disinfection equipment of the present application can be designed as a portable device, such as a handheld device, a wearable device, and the like. A handheld device mainly refers to a device that can be held by a user and easily carried between places of use. The device can be held by a user in some cases, and can also be placed, temporarily fixed, etc. in other cases, and the present application does not limit this. A wearable device mainly refers to a portable device that can be worn by a user, such as a device that can be hung around the neck with a lanyard, or can be worn on the wrist or arm, etc. Such a usage scenario usually requires the overall size of the device to be small, and the corresponding accommodation space in the housing will also be small. This places higher demands on product design, requiring not only that the design of each component inside the device needs to be more compact, but also that the electrical clearance needs to meet safety requirements. In the embodiment of the present application, if the electrical gap between the metal strip and the copper clad layer is small, then during the closed operation of the device, the user touches the metal strip, the user's body is at a high potential, and the contact causes the metal strip to also be at a high potential, while the corresponding copper clad layer is at a low potential. When the potential difference between the two is large, the capacitor formed by the two is easily broken down. High-voltage discharge can also easily cause other related electronic components (such as components in the second sampling circuit on the main control board, other capacitors, resistors, chips, etc.) to be damaged, and it is also easy to produce ozone, affecting the health of the user.

[0060] The design of the second barrier can effectively increase the electrical gap between the metal strip and the copper clad layer to exceed the preset safety value, thereby avoiding damage to other electronic components to a certain extent and improving the electrical reliability of the device. At the same time, the second barrier can also prevent the impact of the electric charge on the copper clad layer in the touch sensing circuit when the user touches the metal strip, so as to prevent the touch sensing circuit from missensing, the main control unit from misjudging, and then mistriggering the associated actions, such as mistriggering the light source, etc. This provides a basis for the compact design of various components inside the device.

[0061] Alternatively, see Figure 5 and Figure 6 In addition to the main control unit, the large resistor 401, etc., the copper layer 221, the second sampling circuit and the connection lines between them can also be integrated on the main control board 200. This implementation method of sampling can reduce parts, further improve the electrical reliability of the device, simplify the assembly process, and reduce production costs.

[0062] It should be understood that the air disinfection device in the embodiment of the present application may also include other possible components, parts, components, etc., such as a battery 701, a mechanical or electronic switch / operating member (such as a button assembly 600), a sensor, etc. For example, see Figure 2 The air disinfection device may also include a battery 701, such as a lithium battery, for providing power to the entire device. The periphery of the battery 701 may be covered with a second protective cover 702, for isolating the battery 701 from some components (such as a main control board, an ion generating component, etc.) in the accommodation space 101.

[0063] It should also be understood that in the description of the present application, the directions or positional relationships indicated by the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. are generally based on the directions or positional relationships shown in the drawings. These directions and positional relationships are for the convenience of description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present application.

[0064] It should also be understood that in the description of this application, unless otherwise specifically defined, the terms "install", "connect", "assemble", "fix" and the like should be understood in a broad sense, for example, they can be fixedly connected, detachably connected or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, they can understand the specific meanings of the above terms in this application according to specific circumstances.

[0065] It should also be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. Unless otherwise clearly and specifically defined, "plurality" means two or more.

[0066] The same and similar parts between the various embodiments in this specification can be referred to each other. The different implementation methods in the above embodiments can be combined with each other as long as they are not contradictory. The above implementation methods do not constitute a limitation on the protection scope of the utility model.
