Description

Technical Field

[0001] The utility model relates to the field of air purification, in particular to an indoor small-sized mobile negative ion purifier. Background Art

[0002] Indoor small mobile negative ion purifier is an environmental optimization appliance that uses negative ions to purify, remove dust, deodorize and sterilize the air. The difference between it and traditional air purifiers is that negative ion purifiers use negative ions as the action factor to actively capture harmful substances in the air, while traditional air purifiers usually use the passive adsorption and filtration purification principle and require regular replacement of filters. Most negative ion generators on the market use single-machine electronic injection technology and bipolar corona discharge devices, but some technologies generate low concentrations of negative ions in the air and poor expansion performance.

[0003] A Chinese invention patent with the publication number CN1876188A proposes an indoor air purifier, including an air filter, the air filter including a box with an air inlet and an exhaust chamber, at least two layers of filter sheets are arranged in the box, the filter sheet is a honeycomb paperboard, and the filter sheet is provided with an air passage that allows air to pass through and is arranged at a density that can filter dust in the air and isolate and adsorb bacteria-carrying particles. Due to the use of a filter sheet with a honeycomb paperboard as the basis and arranged in a layer in the box of the purifier, the incoming air is re-discharged into the room through step-by-step filtration, and because the air passage on the filter sheet is long, the bacteria-carrying particles can be adsorbed in the air passage and killed by a sterilizer.

[0004] The multi-layer filtering and purification structure adopted by the above-mentioned air purifier still has many problems, such as:

[0005] Filtration efficiency issue: Although honeycomb paperboard has a special structure and may have an interception effect on certain particles, its filtration efficiency and filtration performance may not be as good as professional synthetic fiber filter materials, which may limit its filtration ability for fine particles (such as PM2.5).

[0006] Stability of antibacterial performance: The airway on the filter may absorb bacteria-carrying particles, but if the sterilizer in the airway cannot continue to effectively kill bacteria, it may cause bacteria to multiply on the filter and become a source of indoor air pollution.

[0007] Energy consumption: If the fan in the air purifier requires more power to overcome the air resistance caused by the honeycomb paperboard, it may lead to higher energy consumption.

[0008] In summary, although the design concept of this air purifier is novel and creative, it may have shortcomings in filtration efficiency, maintenance cost, energy consumption and aesthetics in actual application, which need further improvement and optimization. Utility Model Content

[0009] The purpose of the utility model is to provide a small indoor mobile negative ion purifier which can purify the air continuously and stably, does not need to be disassembled to replace the filter element, and can release negative oxygen ions.

DETAILED DESCRIPTION Embodiment 1

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] like Figures 1 to 6 As shown, the design of this indoor small mobile negative ion purifier focuses on portability and efficiency, aiming to provide users with an air purification tool that is available at any time. The chassis 2 provides a solid foundation for the machine, ensuring stability and safety when moving indoors. The filter 3 is the first line of defense in the air purification process, which can effectively capture tiny particle pollutants such as dust, pollen, and bacteria in the air. In order to facilitate movement in different rooms or on the ground, the machine is equipped with universal wheels 21, which can easily adapt to various ground conditions, allowing users to effortlessly bring the purifier to where they need it. The housing 1 not only provides protection for the internal mechanical components, but is also designed to be easy to operate, allowing users to easily control the purifier. The variable frequency fan 4 is the core of the air flow, which can automatically adjust the wind speed according to the air purification needs. The wind speed sensor 41 monitors the operating status of the fan to ensure maximum purification efficiency. The fixing ring 11 and the annular micro-electrostatic adsorption filter element 5 are installed on the inner wall of the housing. The filter element 5 adsorbs suspended particles in the air through its micro-electrostatic characteristics, and the main air duct 6 formed is responsible for guiding the smooth flow of air. The control component 7 integrates a series of electronic components and is responsible for the operation control of the entire machine. The negative ion generating device 71 is responsible for generating negative ions, which can help neutralize the positively charged particles in the air, thereby reducing the activity of bacteria and viruses in the air and providing additional purification effects. The auxiliary air duct 8 is located between the control component 7 and the inner wall of the outer shell 1. It is connected to the main air duct 6. An additional layer of charged disinfection filter 81 can further purify the air and eliminate more bacteria and viruses. The air outlet 12 is located at the top of the outer shell 1, close to the control component 7. It is responsible for releasing purified air to ensure that the user can breathe clean air.

[0031] like Figure 2As shown, the design of the filter 3 cleverly incorporates a disassembly handle 31, which allows the user to easily remove the filter for cleaning or replacement. The disassembly handle 31 is usually located in the center of the filter 3, which is convenient for the user to identify and operate. The hexagonal air inlets 32 arranged in an array around increase the surface area of ​​air entering the purifier, thereby improving the air circulation efficiency. The design of these hexagonal air inlets 32 not only optimizes the aerodynamic performance, but also ensures that the air can enter the purifier evenly, improving the overall purification effect. With this design, the purifier can more effectively treat pollutants in the air and provide users with a fresher and healthier indoor air environment.

[0032] like Figure 4 As shown, the design of the fixing ring 11 is not only to fix the annular micro-electrostatic adsorption filter element 5, but also includes an electrode rod 13, which is an innovative technology. The electrode rod 13 extends downward inside and contacts the electrostatic adsorption filter element 5, and charges the filter element through a specific electric field. This charging method can enhance the filter element's adsorption capacity for tiny particles, such as dust, pollen, bacteria, etc., thereby improving the purification efficiency. Above the electrode rod 13, a transformer electrode 14 is also provided. The function of these transformer electrodes 14 is to provide power for the charged disinfection filter 81. The charged disinfection filter 81 is a filter that can use an electric field to kill bacteria and viruses in the air. Through the power provided by the transformer electrode 14, the charged disinfection filter 81 can effectively eliminate microorganisms in the passing air and provide additional purification functions. This design enables the purifier to not only capture pollutants through physical filtration, but also eliminate microorganisms through the action of the electric field, providing a more comprehensive and in-depth air purification solution. Users can therefore enjoy a cleaner and healthier indoor air environment.

[0033] like Figure 5As shown, the design of the control component 7 takes into account the convenience of user operation. At the top of the control component 7, there are buttons 72 for adjusting the wind speed and function mode. These buttons 72 allow users to easily adjust the operating wind speed of the purifier according to personal preferences or the needs of the indoor environment. The user can select the most suitable wind speed setting manually or through a preset intelligent control system. In addition, a microphone 73 is also provided on one side of the button 72. The function of the microphone 73 is to receive the user's voice instructions or voice commands. In this way, the user can operate the purifier by voice control, which improves the convenience and interactivity of use. For example, the user can simply adjust the wind speed, turn on or off a specific function, or ask the status information of the purifier through voice commands. The setting of the microphone 73 may also allow the purifier to be integrated with other smart home systems to achieve a more intelligent home environment. By cooperating with smart speakers or other smart devices, users can remotely control the purifier or incorporate it into the automation scene of the smart home to further improve the quality of life. Overall, the design of the control component 7 not only takes into account the intuitiveness and convenience of user operation, but also incorporates intelligent voice control technology, making the user experience of the purifier more humane and modern.

[0034] like Figure 5 As shown, the core of the control component 7 is the control circuit board 74, which is responsible for the intelligent control and operation management of the entire purifier. On the control circuit board 74, a wind control unit 75 is integrated, which is the brain of wind speed regulation and air flow control. The wind control unit 75 is connected to the wind speed sensor 41 and the button 72, realizing the function of real-time monitoring of wind speed and adjusting wind speed according to user needs. One side of the wind control unit 75 is also equipped with a voice recognition device 76, which is connected to the microphone 73 to form a complete voice control system. The user can issue voice commands through the microphone 73, and the voice recognition device 76 converts these commands into machine-understandable digital signals, and then the wind control unit 75 adjusts the wind speed or other functions according to these signals, thereby realizing intelligent control without manual operation. This design greatly improves the interactive experience of the purifier, and the user can control the purifier more easily, whether it is adjusting the wind speed, switching modes or obtaining device information, it can be completed through simple voice commands. In addition, the voice recognition device 76 can also improve the recognition accuracy and response speed of user voice commands through continuous learning and optimization. In general, the control component 7 forms an efficient voice control system by integrating the control circuit board 74, the wind control unit 75, the voice recognition device 76 and the microphone 73, making the operation of the purifier simpler and more intelligent.

[0035] like Figure 6As shown, the amount of negative ions released by the negative ion generator 71 when it is working is an important performance indicator, which is usually measured in "pieces / cubic centimeter". According to the description, the negative ion generator of the purifier can make the indoor negative ion content reach 80,000 to 100,000 / cubic centimeter. This negative ion concentration level is considered to be beneficial to human health, and can create an air environment close to the natural environment, help relieve people's fatigue, improve sleep quality, enhance immunity, etc.

[0036] Working process

[0037] The working process of this indoor small mobile negative ion purifier is a comprehensive effect of air purification and improvement. First, the air passes through a removable filter to filter large particles and impurities. Then, the air flows through the annular micro-electrostatic adsorption filter element, which uses electrostatic action to remove harmful substances such as tiny particles, bacteria and viruses. The variable frequency fan adjusts the wind speed according to the wind speed signal detected by the wind speed sensor to ensure air circulation and purification effect. The air on the main air duct flows through the control component, and the wind control unit adjusts the fan speed according to user needs or preset programs, while collecting and processing pollutants in the air. The negative ion generator set under the control component releases a large number of negative ions, so that the indoor negative ion content reaches a beneficial level, further improving the air quality. An additional layer of charged disinfection filter is set at the connection between the auxiliary air duct and the main air duct, which uses the electric field to kill microorganisms in the air to ensure cleaner air. Finally, the purified air is released into the indoor space through the air outlet, providing users with a fresh and healthy air environment. During the entire working process, the purifier achieves comprehensive purification and improvement of indoor air through the synergistic effect of multiple filters and functional components, while realizing intelligent control and personalized adjustment through control components and user interaction interface.
