[0036] To clearly and completely describe the technical solution of this application, further explanation will be provided below in conjunction with embodiments and accompanying drawings.

[0037] The inventor's research team previously developed an air sterilization device. In this device, the ion emission electrode is mounted on one circuit board (referred to as the ion emission circuit board), and the high-voltage generating circuit is mounted on another circuit board (referred to as the high-voltage generating circuit board), connected by a wire. When the air sterilization device is operating, the wire needs to withstand high voltage, often reaching several thousand volts or even higher. To avoid or reduce the impact of the high voltage on other components near the wire (such as the main control board, metal structural parts, etc.), in some implementations, the wire can be encased in a high-voltage resistant rubber tube to isolate it; in other implementations, special structural designs can be used, such as maximizing the distance between the wire and other components to achieve isolation.

[0038] Portable air sterilization devices are small in size, with limited internal space, which places higher demands on structural design. This application proposes a novel portable device that integrates the ion emission electrode and high-voltage generating circuit directly onto a single circuit board (hereinafter referred to as the first circuit board). The high-voltage generating circuit is connected to the ion emission electrode through a copper-clad layer on the first circuit board, eliminating the need for separate wires. This simplifies the complex structural design required to isolate such wires and avoids the risk of discharge due to inadequate wire protection. Furthermore, the device in this application embodiment incorporates other optimized structural layouts, resulting in a compact, small, and lightweight device. This portable device is ideal for users to wear, such as around the neck, thereby facilitating the deposition of exogenous allergens around the user's mouth and nose, alleviating rhinitis symptoms, and aiding in rhinitis treatment.

[0039] The structure, function, and assembly process of the portable rhinitis treatment device provided in the embodiments of this application will be further described below with reference to the accompanying drawings.

[0040] See Figures 1 to 9 The portable rhinitis treatment device according to this application includes a housing 100, an ion generating component 300, and a main control unit.

[0041] The housing, as the main supporting structure of the equipment, primarily serves to form a accommodating space. The shape of the housing can be any possible shape, such as a cuboid, cylinder, or a specific object shape; this application does not limit this. For example, such as... Figure 1 and 2 As shown, the housing 100 is shaped like a cuboid and includes an upper housing 110 and a lower housing 120. The sides of the two are connected together, for example, by ultrasonic welding. 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 configuration. The receiving space and the vicinity of the housing can be used to house possible components, such as ion generating components, ion cold spraying components, main control units, batteries, sensors, etc.

[0042] The shell is made of non-metallic materials, such as plastic, glass, ceramic, and rubber. It is understood that when the shell comprises multiple different components, these components can be made of the same or different materials, and this application does not limit this. For example, when the shell includes components such as side walls, an upper cover, and a lower cover, the side walls can be made of plastic or ceramic materials, and the upper and lower cover can be made of plastic or glass materials. As another example, when the shell includes... Figure 2 When the upper shell 110 and lower shell 120 are shown, both the upper shell 110 and lower shell 120 can be made of plastic or the like, or they can each be made of different materials. It is also understood that in some cases, metal components may be partially disposed, installed, or embedded in the shell; this application does not limit this, as long as it does not affect the basic function of the device in generating and releasing negative ions. For example, components such as... can be provided on both sides of the shell. Figure 1 The implementation of the metal strip 401 shown will be further explained later.

[0043] The ion generating component is housed within the containment space and is primarily used to generate and release electrons. Under high voltage, the ion generating component ionizes to produce electrons, most of which are captured by O2 in the air to form negative oxygen ions, which are then transported into the ambient space. In this embodiment, the ion generating component can be an existing ion generator or other possible structures.

[0044] See also some possible implementations. Figure 2The ion generating component 300 includes a high-voltage generating circuit 312 and an ion emitting electrode 311. The high-voltage generating circuit generates a negative DC high voltage and inputs it to the ion emitting electrode, which then ionizes the air under the negative high voltage, releasing electrons into the air. As mentioned earlier, in previous air disinfection devices, the high-voltage generating circuit and the ion emitting electrode were respectively placed on two circuit boards. However, in this embodiment, they are integrated on a single circuit board, namely the first circuit board 310. The two are electrically connected through traces on the copper-clad layer (not shown in the figure) on the first circuit board 310, eliminating the need for separate wires. The copper-clad layer, while providing electrical connection, also has a certain electromagnetic shielding effect, reducing the influence of high-voltage electric fields on the circuit and providing a certain degree of high-voltage protection.

[0045] See also some possible implementations. Figure 1 , Figure 2 and Figure 4 An open groove is formed on the first surface 103 of the housing 100, which is mainly used to set the carbon brush, and is also referred to as the carbon brush groove 104 below. The ion emission electrode includes a carbon brush 3111, which is disposed in the carbon brush groove 104. The bottom end of the carbon brush 3111 is disposed on the first circuit board 311, and the top end faces the external environment of the housing 100.

[0046] When the ion generator is working, the carbon brush, under the influence of a negative DC high voltage, generates a high-voltage corona discharge at its tip. This discharge continuously ionizes the air, forming a large number of positive and negative ion pairs. Positive ions, due to the negative high voltage, move towards the bottom of the carbon brush and eventually neutralize it, while a large number of electrons are rapidly released into the air through the tip of the carbon brush. Electrons have extremely short lifespans (nanoseconds) and cannot exist in the air for long periods. Furthermore, their affinity for oxygen is much greater than that for other gases in the air, such as CO2 and N2. Therefore, most of the ionized electrons are captured by oxygen to form negative oxygen ions. These negative oxygen ions are repelled by the negative high-voltage electric field and move away from the tip of the carbon brush, thus creating a negative ion wind. Negative oxygen ions carry a negative charge. Many airborne allergens, such as dust, pollen, dust mites, and bacteria, are usually positively charged or uncharged. When these positively charged particles encounter negative oxygen ions, the negative ions attract them electrostatically, forming larger composite particles. Negative oxygen ions can also alter the surface charge and physical properties of some particulate matter, causing allergens that were originally suspended in the air to settle. Furthermore, negative oxygen ions may induce aggregation between multiple particles. All of these factors can cause the composite / aggregated particles to become heavier, unable to remain suspended in the air, and eventually settle to the ground due to gravity. This reduces the concentration of allergens in the air (especially near devices), which helps alleviate rhinitis symptoms caused by allergens in users.

[0047] The main control unit is also housed in the accommodating space 101. A typical control unit is a unit capable of issuing various control commands to control the operation of connected components to achieve specific functions. In this application, the control unit is used as the main controller of the device, hence the name "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 in other possible ways, such as by improving existing hardware and programs. In some possible implementations, the main control unit is mounted on a circuit board; for ease of distinction, this embodiment also refers to it as a main control board, such as... Figure 2 As shown. It is understood that, in addition to the main control unit, other possible components may be installed on the main control board 201, and this application does not limit this.

[0048] The main control unit can be electrically connected to the ion generating component and output control signals to it to control its generation and release of electrons, such as controlling the ion generating component to start or stop emitting negative ions, or to increase or decrease the number of negative ions emitted. For example, such as... Figure 3 and Figure 9 As shown, the main control unit on the main control board 310 can be electrically connected to the ion generating component via the ion control line 313.

[0049] In some possible implementations, the ion emission electrode is positioned between the high-voltage generation circuit and the main control unit. For example, such as... Figure 2 , Figure 3 and Figure 9 As shown, the entire ion generating assembly 300 is located in the upper half of the portable rhinitis treatment device. The high-voltage generating circuit 312 is positioned at the head of the device, the ion emitting electrode 311 is below the high-voltage generating circuit 312, and the main control board 310 is located in the lower half. This arrangement effectively reduces the distance between the high-voltage generating circuit and other electronic components such as the main control unit within the limited space of the portable device, thereby minimizing the impact of the high-voltage generating circuit on these components.

[0050] See also some possible implementations. Figure 3 and Figure 9The high-voltage generator 312 has a potting shell 321 on its upper cover, and the potting shell 321 is filled with insulating material (not shown in the figure). The potting shell in this embodiment can take any possible shape, and this application does not limit it. The insulating material can be epoxy resin, polyimide, or other possible materials. Exemplarily, the insulating material can be in a fluid state during potting, and can be cured after a period of time or after the addition of specific components, so that the first circuit board, the potting shell, and the insulating material form a solid whole, which facilitates subsequent assembly and other steps.

[0051] Understandably, when filled with insulating material, the aforementioned copper-clad layer is also protected by the insulating material. The copper-clad layer, in conjunction with the insulating material, further enhances protection, reducing or preventing electric shocks or short circuits caused by excessive voltage. This protects components such as transformers in high-voltage generating circuits and minimizes impact on other electronic components within the equipment. Furthermore, since the potting shell and insulating material have a certain thickness after curing, placing them at the head of the equipment, rather than in the middle, reduces the impact on the layout of other components, contributing to a more compact design and achieving overall miniaturization and thinning of the equipment.

[0052] Optionally, see Figure 3 and Figure 9 The first circuit board 310 may be provided with fastening holes 331, and during assembly, the first circuit board 310, the potting shell 321, the insulating material, etc. can be fixed as a whole to the housing of the equipment by fasteners 322.

[0053] Optionally, when the ion generating component is connected to the main control unit via the ion control line, one end of the ion control line connected to the ion generating component can also be protected by an insulating material, while the other end can be a detachable structure, such as a plug-in connection structure, in which case the other end can be plugged into the main control unit or the main control board where the main control unit is located during assembly.

[0054] Optionally, since the high-voltage generating circuit and the potting shell are located at the head of the portable rhinitis treatment device, to avoid increasing the length and size of the portable device, the structure for opening a lanyard hole at the head of the shell and reserving space for installing a lanyard can be omitted. Instead, structures for connecting to the lanyard can be provided on both sides of the outer exterior of the shell. For example, the structure could be as follows: Figure 1 and Figure 9 The lanyard connector 105 is shown in the form of an outwardly protruding ear.

[0055] In some possible implementations, a lighting component is also provided on the first surface of the housing. This lighting component is electrically connected to the main control unit and serves at least to indicate the device's operating status, allowing the user to visually and intuitively understand the device's working condition and improving the user experience. For example, the lighting component can indicate whether the device is in operation, its operating mode, or the intensity of negative ion emission. Of course, the lighting component can also be used to indicate other information, such as whether the device is charging. It is understood that the specific information indicated by the lighting component can be configured according to actual needs, and this application does not limit this.

[0056] See also some possible implementations. Figure 2 , Figure 4 and Figure 5 The lighting assembly may include a lamp panel 501. The lamp panel is a major component of the lighting assembly, primarily used to generate light under the control of the control unit, and in some possible implementations, it can also be used to adjust the lighting effects. A second opening 502 may be provided on the lamp panel 501 for the carbon brush 3111 to pass through.

[0057] Optionally, see Figure 6 The lamp board may include a second circuit board 510. The second circuit board may be a rigid circuit board or a flexible circuit board; this application does not limit this. A light source 511 is disposed on the second circuit board 510. The light source may, exemplarily, take the form of LED beads or other possible forms; this application does not limit the form or specific number of light sources. The second circuit board 510 is electrically connected to the main control unit to supply power to the light source, at least through the main control unit. In some possible implementations, the main control unit may also send control commands, signals, or other possible information to the second circuit board to control the light source. For example, such as... Figure 6 and Figure 9 As shown, the second circuit board 510 can be connected to the main control unit via the lamp board wire 513.

[0058] Optionally, see Figure 6 The light panel may also include a diffuser plate 520. The diffuser plate can be any type of diffuser plate found in the prior art; this application does not limit the shape, material, etc., of the diffuser plate. For example, the diffuser plate may be made of... Figure 6 The circular acrylic diffuser shown is an example. The diffuser is positioned above the second circuit board to scatter at least a portion of the light emitted by the light source onto the first surface, thereby allowing the user to observe a relatively uniform and soft lighting effect from outside the device.

[0059] Optionally, see Figure 6The diffuser plate has at least one notch 521, and the light source 511 is correspondingly disposed at the notch 521. The notch can be any possible shape such as circular, trapezoidal, or triangular, and this application does not limit it. In this way, on the one hand, at least part of the light emitted by the light source can enter the diffuser plate through the side wall at the notch, thereby scattering more light onto the first surface; on the other hand, the second circuit board, the light source such as the lamp bead, and the diffuser plate itself also have a certain thickness. If the three are directly stacked one on top of the other, the thickness will be large. However, by placing the light source at the notch of the diffuser plate, the overall thickness after stacking can be effectively reduced, which is conducive to reducing the thickness of the device and making the device smaller and thinner.

[0060] Optionally, see Figure 6 A third opening 512 may be formed on the second circuit board 510, and a fourth opening 522 may be formed on the diffuser board. The third opening 512 and the fourth opening 522 are mainly used for the carbon brush 3111 to pass through. The third opening and the fourth opening can be of any possible shape, as long as they allow the carbon brush to pass through without affecting its normal operation. For example, their shape can be the same as or similar to the shape of the carbon brush groove, for example... Figure 4 and Figure 6 As shown, the carbon brush groove is waist-shaped, and the third opening 512 and the fourth opening 522 are also waist-shaped.

[0061] Optionally, the fourth opening may communicate with the aforementioned notch. For example, as shown... Figure 6 As shown, the notch 521 is trapezoidal and connects to the edge of the waist-shaped fourth opening 522. This design allows light to enter the diffuser plate from the sidewalls of the notch and the fourth opening, increasing the amount of light entering the diffuser plate and making the lighting assembly appear brighter under the same light source conditions.

[0062] Optionally, when multiple light sources are provided on the second circuit board, the light sources can be positioned corresponding to the sidewalls of the notch and / or the second opening, thereby better directing the light from the light sources into the diffuser plate. For example, as shown... Figure 5 and Figure 6 As shown, the second circuit board 510 is equipped with six LEDs, which are respectively positioned corresponding to the upper base and two sides of the two trapezoidal notches 521. That is, each upper base / side of the trapezoidal notch is respectively equipped with a light source 511. It is understood that this application does not limit the specific correspondence between the light source and the sidewall of the notch and / or the second opening. It can adopt a one-to-one correspondence as in the previous example, or it can be a one-to-many, many-to-one, or many-to-many relationship, which can be set according to different situations.

[0063] Optionally, see Figure 6A first reflective surface is provided on the outer peripheral sidewall of the diffuser to prevent light from escaping from the outer peripheral sidewall of the diffuser. For example, the first reflective surface can be a reflective sticker, which is wrapped around and fixed to the outer peripheral sidewall of the diffuser, for example, by adhesive.

[0064] Optionally, see Figure 6 A first diffuser film is provided on the environmentally facing side of the diffuser. The shape, openings, etc., of the first diffuser film can be adapted to the diffuser film. The first diffuser film can further homogenize and disperse the light emitted from the diffuser film, thereby making the light observed by the user softer and more uniform. This application embodiment does not limit the thickness, color, material, etc., of the first diffuser film. For example, the first diffuser film can be a white plastic film with a thickness of 0.1-0.5 mm.

[0065] Optionally, see Figure 6 A second diffuser film is provided on the side of the diffuser plate facing the receiving space. The second diffuser film may have the same or different properties as the first diffuser film, and this application does not limit this.

[0066] Optionally, a second reflective surface is provided on the side of the diffuser facing the receiving space. The second reflective surface can reflect light emitted from the side of the diffuser facing the receiving space.

[0067] By setting a second diffuser or a second reflective surface, light emitted from the side of the diffuser facing the accommodating space can be diffused or reflected, preventing too much light from escaping from the side of the diffuser facing the accommodating space, improving the utilization rate of the light emitted by the light source, and making the light inside the diffuser more uniform, thus presenting a more comfortable lighting effect for the user.

[0068] See also some possible implementations. Figure 1 , Figure 4 , Figure 6 and Figure 8 The lighting assembly may also include a cover plate 504, which can be positioned above the diffuser plate 520. After the cover plate 504 is installed, its outer surface is flush with or substantially flush with the first surface of the housing 100. The cover plate may be made of a material that is wholly or partially translucent, and this application does not limit this choice.

[0069] Optionally, see Figure 4 and Figure 9 A first wire-passing hole 106 can be formed on the housing for the lamp board wire 513 of the lighting assembly to pass through. It is understood that if a second diffuser film or a second reflective surface is provided on the side of the diffuser facing the receiving space, a wire-passing hole for the lamp board wire 513 to pass through can also be provided on the second diffuser film or the second reflective surface.

[0070] Optionally, see Figure 4 and Figure 5 The housing can protrude outwards to form a protruding positioning part 107. This positioning part can be made of... Figure 4 The cylindrical shape shown can also be other possible shapes such as a square column, and this application does not limit this. A through hole 503 adapted to the positioning part 107 can be provided on the lamp plate 501 for the positioning part 107 to pass through. It is understood that when the lamp plate includes components such as a diffuser plate, a second circuit board, and a diffuser film, these components can correspondingly have through holes. In some cases, the notch 521 provided on the diffuser plate 520 can also serve as the aforementioned through hole for the positioning part 107 to pass through, without the need for additional notches, such as... Figure 6 As shown. During assembly, the positioning part passes through the corresponding through hole, which facilitates assembly and prevents the components in the lamp panel assembly from moving arbitrarily after assembly.

[0071] See also some possible implementations. Figure 1 The device also includes an obstruction detection component 600 disposed on the housing 100. The obstruction detection component is mainly used to detect whether there are obstructions or obstacles in a specific detection area near the carbon brush. It is understood that the obstruction detection component can be placed in any possible location, as long as its detection area at least covers the area around the carbon brush. The structure of the obstruction detection component can adopt existing structures in the prior art, or other possible structures. Several exemplary implementation methods will be provided below for further explanation.

[0072] For example, see Figure 7 , Figure 8 and Figure 4 The occlusion detection assembly may include a sensor cover 620 and a sensor 611. The housing 100 has a first opening 108, the sensor cover 620 covers the first opening 108, and a viewing window 622 is provided on the sensor cover 620 facing the carbon brush.

[0073] The sensor can be, for example, any possible transmitter-receiver sensor such as infrared or TOF (Time Offlight), or any other sensor capable of detecting obstacles or obstructions. This application does not limit the specific type of sensor. The sensor is housed inside the sensor housing, corresponding to the viewing window, so that the detection area near the carbon brush can be detected through the viewing window.

[0074] Sensor 611 is electrically connected to the main control unit, for example, via sensor cable 612. Optionally, when the device is operating normally, if the main control unit receives a preset signal from the sensor indicating the presence of an obstruction within the detection area, it can send a stop command to control the ion generating component to cease operation. This approach prevents direct contact between living organisms or objects and the carbon brushes, thus avoiding unnecessary adverse effects and further enhancing the electrical safety of the device.

[0075] Optionally, the aforementioned sensor can be a wide-viewing-angle sensor, for example, with both the horizontal and vertical viewing angles greater than 40 degrees. A wide-viewing-angle sensor can appropriately expand the detection area, allowing the ion emission electrode to stop working and cease emitting negative ions before a living organism or object enters the detection area and makes contact with the carbon brush. Of course, since the portable device of this embodiment is carried by the user, the sensor's viewing angle is generally not too large, for example, not greater than 90 degrees, to avoid excessive false detections and miscontrols due to user actions or objects around the user, thus affecting the user experience.

[0076] Optionally, the viewing window can be achieved by opening an opening in the sensor housing and providing a cover plate that allows light or waves to pass through. The cover plate can be made of materials such as acrylic or glass, and can be attached to the sensor housing by means of adhesive, fastening, snap-fit, or other methods. This application does not limit the specific material or method of attachment of the cover plate. Providing a cover plate helps protect the sensor inside the sensor housing.

[0077] See also some possible implementations. Figure 1 The device also includes a button assembly 700. The button assembly is primarily used to control the device's on / off state. Of course, in some cases, the button assembly can also be used to input other commands, such as long-pressing to put the device into sleep mode. This application does not limit the specific commands or signals that the button assembly can input. The structure of the button assembly can adopt existing structures in the prior art, or other possible structures, such as mechanical buttons, touch buttons, etc.

[0078] The button assembly and the occlusion detection assembly can be independently located in different positions on the housing, or they can be combined. In some possible implementations, participants... Figure 1 and Figure 2 The button assembly 700 can be embedded in the occlusion detection assembly 600, making the overall appearance of the device simpler and reducing the space occupied on the housing surface, making it more suitable for portable devices with limited surface space.

[0079] Optionally, see Figure 2 , Figure 4 and Figure 7The sensor cover 620 can be disposed on the first surface 103 of the housing. The top of the sensor cover 620 is provided with a button hole groove 623 for mounting the button assembly 700 or some of its components.

[0080] Optionally, see Figure 1 , Figure 2 and Figure 7 The button assembly 700 may include a button 710 and a waterproof plug 720.

[0081] The button 710 may include a keycap 711 and a keypost 712. One end of the keypost 712 is connected to the keycap 711, and the other end passes through the keyhole slot 623 on the sensor cover 620 and extends into the receiving space 101 to abut against the switch control position in the main control unit. The keycap 711 of the button is embedded in the sensor cover 620, flush or substantially flush with the sensor cover 620, forming a relatively flat or smooth surface.

[0082] A waterproof plug 720 is disposed on the outer periphery of the key post 712, and is tightly fitted with both the key post 712 and the sensor cover 620. Its main function is to prevent liquid from outside the housing from entering the containment space through the gap between the key post and the sensor cover. For ease of distinction and description, the contact surface between the key post and the waterproof plug can be referred to as the first contact surface, and the contact surface between the waterproof plug and the sensor cover as the second contact surface. The tight fit between the key post and the waterproof plug, and between the waterproof plug and the sensor cover, makes it difficult for liquid to enter the containment space through the first and second contact surfaces.

[0083] Optionally, the waterproof plug can be made of a material with a certain degree of elastic deformation, such as silicone, to improve the sealing between the parts in contact with it through interference fit and other means, thereby effectively improving the waterproof performance of the button location of the device.

[0084] Optionally, see Figure 7 The key post 712 has a recessed mating position 7121, and one side of the waterproof plug 720 is embedded in the mating position 7121. The waterproof plug 720 and the key post 712 are also interference-fitted. This method increases the area of ​​the first contact surface, effectively preventing loosening or leakage of the connection due to user pressing, external vibration, or impact, improving the sealing between the two, and further enhancing waterproof performance.

[0085] Optionally, see Figure 8 and Figure 9The sensor assembly also includes a mounting plate 630. The mounting plate 630 is connected to the sensor cover 620, and can be exemplarily connected by a threaded connection or similar method to press the contact surface between the waterproof plug and the sensor cover (i.e., the second contact surface), and the contact surface between the waterproof plug and the mounting plate (also referred to as the third contact surface in this embodiment for easy distinction). This approach not only further improves the waterproof performance between the sensor cover and the button assembly, but also secures the sensor between the sensor cover and the mounting plate, ensuring stability even when the device is subjected to significant external impacts or vibrations while being carried.

[0086] Optionally, any of the rhinitis treatment devices in the embodiments of this application may further include an ion cooling spray component. The ion cooling spray component is mainly used to enable the device to operate in a closed manner when the user comes into contact with certain components of the ion cooling spray component, working together with the ion generating component to form a directional cooling spray of negative ions directed towards the user, thereby locally increasing the concentration of negative oxygen ions in the user's area.

[0087] The ion spray assembly can employ existing structures or other possible structures. For example, the ion spray assembly may include a metal strip and a large resistor.

[0088] The metal strip can be disposed on the outer surface of the housing, with at least a portion of it exposed to the environment and accessible to the user. This application does not limit the specific shape or number of the metal strip; it can be elliptical, square, oblong, irregularly shaped, etc., and is not required to be strip-shaped, as long as it provides a certain contact surface for the user to access. For example, such as... Figure 1 and Figure 2 As shown, metal strips 401 can be respectively provided on both sides of the housing 100. Oval-shaped holes are respectively opened on both sides of the housing 100, and the metal strips 401 are adapted to be embedded in the oval-shaped holes, with their outer surfaces exposed to the environment and flush or substantially flush with the outer surface of the housing 100. When the user holds the device, they can naturally come into contact with these metal strips. Alternatively, the metal strips can also be provided on the first surface of the upper shell, the second surface of the lower shell, or other locations convenient for the user to access.

[0089] A large resistor (not shown in the figure) can be placed in the accommodating space 101, for example, on the main control board. Large resistors are also commonly referred to as high-value resistors, high-resistance resistors, etc. In this embodiment, the large resistor can be a resistor with a resistance value at the kiloohm level or higher, such as megaohm level or higher, so that the current passing through the large resistor during operation does not exceed the microamp level, thereby meeting higher product standards, such as medical electrical equipment standards. It is understood that the large resistor in this embodiment can refer to a single resistor or a component composed of multiple resistors and other possible electronic components; this application does not limit this, as long as its resistance value reaches at least the kiloohm level.

[0090] Alternatively, the connection lines between the large resistor and the metal strip, and between the large resistor and the main control unit, can also be located on the main control board. This method offers a simple structure, relatively reliable electrical characteristics, and relatively low cost.

[0091] One end of the large resistor is electrically connected to the metal strip, and the other end is grounded. This forms a path from the metal strip, through the large resistor, to the ground. In some implementations, a digital ground can be provided on the circuit board (e.g., the main control board), and the other end of the large resistor can be directly or indirectly connected to this digital ground. Of course, in other implementations, the other end of the large resistor can also be connected to signal ground, etc.

[0092] This rhinitis treatment device can operate in either an open or closed mode, depending on whether the conductive medium in the user's environment is in contact with the metal strip or not. In open mode, a large number of electrons are released into the air through the carbon brush tip and captured by oxygen to form negative oxygen ions. These negative oxygen ions are then repelled by the negative high-voltage electric field, creating a negative ion wind. This open structure uses the carbon brush as the negative electrode and the entire space around the device (e.g., the ground, a tabletop) as the positive electrode, creating a high-voltage electrostatic field between the positive and negative electrodes. This field fills the entire space, significantly improving the diffusion of negative oxygen ions into the surrounding space, resulting in good diffusion and a high ion concentration, making it suitable for providing better allergen settling capabilities around the device. When the user's body parts are in contact with the metal strip, such as when the user holds the device, the device operates in a closed mode. Under the influence of the negative high voltage, the carbon brush tip also rapidly releases electrons into the air, forming negative oxygen ions. Unlike other methods, this method involves the user's body contacting a metal strip, which is grounded through a high resistance. The user's body is at a high potential relative to the carbon brush (negative high voltage), creating a closed electrode between the carbon brush and the body. This forms a strong electric field, causing more negative oxygen ions near the carbon brush to be transported towards the user's area (e.g., the head and face), creating a directional, cold-spray negative ion airflow. This locally increases the concentration of negative oxygen ions in the area, improving local disinfection. Simultaneously, the directional blowing of the cold-spray negative ion airflow enhances the body's ability to inhale negative oxygen ions through the respiratory tract, further strengthening allergen deposition and alleviating rhinitis. Inhaling negative oxygen ions can also enhance cardiovascular function and improve overall bodily function. Furthermore, the high resistance prevents excessively high electric field strength between the carbon brush and the body, thus minimizing ozone production in the closed-loop operation and effectively preventing ozone exceedances.

[0093] It is understood that the portable rhinitis treatment device in this application embodiment may also include other possible components, parts, and elements, such as batteries and battery cases. For example, see [link to relevant documentation]. Figure 2 The portable rhinitis treatment device may also include a battery 701, such as a lithium battery, to provide power to the entire device. The battery 701 may be covered by a battery case 702 to isolate the battery 701 from some components (such as the main control board 201, the ion generating component 300, etc.) in the housing space 101.

[0094] The following provides an exemplary assembly process for a portable rhinitis treatment device according to an embodiment of this application.

Snap the sensor cover and button assembly together into the first opening 108 on the outside of the upper shell 110, insert the fixing plate 630 from the inside of the upper shell 110, and secure the fixing plate 630 to the upper shell 110 with screws. In this way, the fixing plate 630 and the sensor cover 620 can be clamped and fixed to the upper shell 110.
