Description

Technical Field

[0001] This invention relates to the field of air purification equipment technology, specifically to a micro-electrostatic coupling negative ion purification and disinfection device. Background Technology

[0002] Traditional air conditioning and other equipment lack effective purification capabilities for particulate matter containing bacteria, viruses, and other microorganisms in indoor air. Therefore, people use micro-electrostatic purification devices installed below air conditioners to purify indoor air. These devices use ionization modules to attach ions to airborne particles, attracting these charged particles and collecting bacteria, viruses, and other microorganisms attached to them, which are then killed in a strong electric field. However, existing micro-electrostatic purification devices typically use high-voltage discharge needles or tungsten wires, which can easily accumulate ozone, harming the respiratory system. Furthermore, cleaning the dust collection screen in these devices is troublesome, and failure to clean it promptly significantly reduces the purification effect.

[0003] A Chinese invention patent with publication number CN113245063B discloses an ultra-thin micro-electrostatic air purifier, comprising: a shell with an air inlet and an air outlet; a discharge mechanism near the air inlet, including a rotating rod and multiple discharge units, each discharge unit including a fixed base, a cathode needle, and an anode needle, the fixed base being connected to the rotating rod, the cathode needle and anode needle being connected to the fixed base and perpendicular to the rotating rod, the rotating rod being rotatably connected to the shell; at least one micro-electrostatic filter near the air outlet, parallel to the rotating rod; and a high-voltage power supply electrically connected to the discharge units and the micro-electrostatic filter; in the working state, the rotating rod rotates to adjust the cathode needle and anode needle to be perpendicular to the air inlet, and in the non-working state, the rotating rod rotates to adjust the cathode needle and anode needle to be internally housed in the shell.

[0004] Although its micro-electrostatic purification can purify harmful substances in indoor air to a certain extent, its high-voltage discharge needle method still produces ozone, which accumulates and can be harmful to the human body. Furthermore, its filter is inconvenient to clean, which can easily affect the purification effect. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a micro-electrostatic coupling negative ion purification and disinfection device. The device includes a housing, a purification mechanism within the housing, a charged component disposed within the housing in the purification mechanism, a dust collection component below the charged component, and a control component above the charged component. The charged component includes a regulated power supply a disposed inside the housing and several carbon brushes disposed at the bottom of the housing. A negative ion generator is disposed on one side of the regulated power supply a. This invention solves the problems of existing technologies, such as the discharge method easily generating and accumulating ozone that is harmful to the human body, and the dust collection area being inconvenient to clean.

[0006] The technical solution of the present invention is as follows:

[0007] A micro-electrostatic coupling negative ion purification and disinfection device includes a housing, within which a purification mechanism is disposed. The purification mechanism includes a charging component disposed inside the housing, a dust collection component disposed below the charging component, and a control component disposed above the charging component. The charging component includes a regulated power supply a disposed inside the housing and several carbon brushes disposed at the bottom of the housing. A negative ion generator is disposed on one side of the regulated power supply a. The control component is used to control the charging component and the dust collection component to turn on and off. The negative ion generator controls the carbon brushes to charge particulate matter while generating negative ions, and the dust collection component adsorbs the charged particulate matter.

[0008] As a preferred embodiment, the top of the housing is provided with an air inlet grille, the bottom of the housing is provided with an air outlet grille, the sides of the housing are provided with mounting plates, and the inside of the housing is provided with a power supply box.

[0009] As a preferred embodiment, the dust collection assembly includes a regulated power supply b disposed inside the housing and an insert plate fixedly disposed inside the housing. The insert plate is provided with a micro electrostatic dust collection screen, and rotating rods are fixedly connected to both sides of the micro electrostatic dust collection screen. The insert plate has a sliding groove a, and the micro electrostatic dust collection screen is provided with a pull ring.

[0010] As a preferred embodiment, the control components include a controller disposed inside the housing and an airflow sensor disposed on the top of the housing.

[0011] As a preferred embodiment, the purification mechanism is provided with a cleaning mechanism, which includes a support component disposed below the dust collection component and a brush component disposed on the support component.

[0012] As a preferred embodiment, the support assembly includes a support plate slidably disposed in a chute a and a chute b formed on a micro electrostatic dust collection screen plate, wherein the support plate is provided with a rotation hole.

[0013] As a preferred embodiment, the cleaning assembly includes a slide plate slidably disposed within a slide groove b, with sliders fixedly connected to both sides of the slide plate, and a brush disposed at the bottom of the slide plate.

[0014] As another preferred embodiment, the cleaning assembly further includes a window opened on one side of the housing and a rotating seat fixedly disposed above the window, wherein a baffle is hinged to the rotating seat.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention features a charging component that provides power to the negative ion generator via a regulated power supply (a). The negative ion generator controls the carbon brush to discharge, charging the blown-in particles with negative electrons. The charged particles are then adsorbed by a micro-electrostatic dust collection screen that is powered on below, thus purifying harmful substances such as bacteria and viruses. The carbon brush does not produce ozone during the charging process, and the negative ions generated by the negative ion generator can be introduced into the room, which is more beneficial to human health.

[0017] This invention includes a cleaning component. After prolonged use, the micro-electrostatic dust collection screen needs to be cleaned of the adsorbed particles on its surface to prevent clogs caused by excessive particle accumulation, which would affect the adsorption and purification effect of the micro-electrostatic dust collection screen. Cleaning is simple: just pull the micro-electrostatic dust collection screen out of the housing using the support component, then flip the screen over, and finally move the sliding plate to clean it effectively and promptly using the brushes on the plate. This simple and efficient cleaning method ensures the smooth operation of the micro-electrostatic dust collection screen.

[0018] In summary, this invention has the advantages of not producing ozone, generating negative ions that are beneficial to the human body, being able to easily clean the micro-electrostatic dust collection screen, having good linkage between components, and having a simple structure, making it suitable for the field of air purification equipment technology.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Example 1

[0028] like Figures 1 to 6As shown, a micro-electrostatic coupling negative ion technology purification and disinfection device includes a housing 1. The housing 1 contains a purification mechanism 2, which includes a charging component 21 disposed inside the housing 1, a dust collection component 22 disposed below the charging component 21, and a control component 23 disposed above the charging component 21. The charging component 21 includes a regulated power supply a210 disposed inside the housing 1 and several carbon brushes 211 disposed at the bottom of the housing 1. A negative ion generator 212 is disposed on one side of the regulated power supply a210. The control component 23 controls the charging component 21 and the dust collection component 22 to open and close. The negative ion generator 212 controls the carbon brushes 211 to charge particulate matter while generating negative ions, and the dust collection component 22 adsorbs the charged particulate matter. The negative ion generator 212 controls the carbon brushes 211 to discharge, charging the particulate matter in the blown-in air with negative electrons. The charged particles are then adsorbed by the energized micro-electrostatic dust collection screen 222 below, thus purifying harmful substances such as bacteria and viruses. A regulated power supply a210 is connected to the negative ion generator 212 via wires, providing a 12V switching power supply. The carbon brushes 211 have 28 units, and the negative ion generator 212 is connected to the carbon brushes 211 via four wires, each wire controlling seven carbon brushes. The position and angle of the carbon brushes can be adjusted. A210 provides power to the negative ion generator 212, which controls the carbon brush 211 to discharge, charging particulate matter in the blown-in air with negative electrons. The charged particulate matter is then adsorbed by the energized micro-electrostatic dust collection screen 222 below, thus purifying harmful substances such as bacteria and viruses. The carbon brush 211 does not produce ozone during the charging process, and the negative ions generated by the negative ion generator 212 can be sent into the room, which is more beneficial to human health and improves indoor air quality. This solves the problem that existing technologies easily generate and accumulate ozone, which is harmful to the human body.

[0029] like Figure 1 and Figure 2As shown, the top of the housing 1 is provided with an air inlet grille 11, the bottom of the housing 1 is provided with an air outlet grille 12, the two sides of the housing 1 are provided with mounting plates 13, and the inside of the housing 1 is provided with a power supply box 14. The housing 1 can be installed at the air conditioner's air outlet and return air inlet. When installed at the air conditioner's air outlet, the air blown out by the air conditioner enters through the air inlet grille 11. The charged particles blown into the air inlet grille 11 are charged with negative electrons by the charging component 21, and the charged particles are adsorbed by the dust collection component 22 below, purifying harmful substances such as bacteria and viruses carried by the particles. At the same time, the negative ions generated by the charging component 21 can be directly sent into the room, which is more beneficial to human health. Purifying the air blown out by the air conditioner at the first time is more conducive to protecting human health. The housing 1 can be drilled and threaded through the mounting plate 13. The mounting plate 13 is magnetic and can also be magnetically installed or hung. The mounting plate 13 is detachable for other installation methods. The power supply box 14 is threaded inside the housing 1 and can protect the internal regulated power supply a210, negative ion generator 212, regulated power supply b220 and controller 230. The power supply box 14 is detachable for easy maintenance.

[0030] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the dust collection assembly 22 includes a regulated power supply b220 disposed inside the housing 1 and an insert plate 221 fixedly disposed inside the housing 1. A micro-electrostatic dust collection mesh 222 is disposed on the insert plate 221, and rotating rods 223 are fixedly connected to both sides of the micro-electrostatic dust collection mesh 222. A sliding groove a224 is provided on the insert plate 221. The regulated power supply b220 provides a 220V high-voltage power supply to the micro-electrostatic dust collection mesh 222, enabling the micro-electrostatic dust collection mesh 222 to adsorb charged particles, thereby achieving a purification effect. The micro-electrostatic dust collection mesh 222 is inserted into the insert plate 221, allowing for easy disassembly and installation. The rotating rods 223 cooperate with the rotating holes 312 on the support plate 310, allowing the micro-electrostatic dust collection mesh 222 to be flipped, facilitating cleaning by the cleaning assembly 32. The cleaned particles fall directly into the collection container below for collection.

[0031] like Figure 2As shown, the control component 23 includes a controller 230 disposed inside the housing 1 and an airflow sensor 231 disposed on the top of the housing 1. The airflow sensor 231 can sense the airflow from the air conditioner. The airflow sensor 231 is electrically connected to the controller 230. When the airflow sensor 231 senses airflow from the air conditioner or no airflow, it sends a signal to the controller 230. The controller 230 is electrically connected to the regulated power supply a210 and the regulated power supply b220. After the airflow sensor 231 sends a signal to the controller 230, the controller 230 sends signals to the regulated power supply a210 and the regulated power supply b220 to control their opening or closing. This allows the device to be opened and closed synchronously with the air conditioner, enabling timely air purification and timely closing when the air conditioner is turned off, effectively saving electricity.

[0032] like Figure 4 As shown, the purification mechanism 2 is equipped with a cleaning mechanism 3, which includes a support component 31 located below the dust collection component 22 and a brush component 32 located on the support component 31. During cleaning, simply pull the micro-electrostatic dust collection screen 222 out of the housing using the support component 31, then flip the micro-electrostatic dust collection screen 222 over, and then move the sliding plate 320 to easily and effectively clean the micro-electrostatic dust collection screen 222 using the brush 322 located on the sliding plate 320.

[0033] like Figure 5 and Figure 6 As shown, the support assembly 31 includes a support plate 310 slidably disposed within a slide groove a224 and a slide groove b311 formed on the micro electrostatic dust collection screen 222. A rotating hole 312 is provided on the support plate 310. The rotating hole 312 matches a rotating rod 223 on the micro electrostatic dust collection screen 222. The micro electrostatic dust collection screen 222 is rotatably disposed on the support plate 310 via the cooperation of the rotating rod 223 and the rotating hole 312, enabling it to flip over. When the device is not in operation and cleaning of the micro electrostatic dust collection screen 222 is required, the support plate 310 can carry the micro electrostatic dust collection screen 222 out of the housing 1 along the slide groove a224, allowing the screen to flip over and complete the cleaning process, which is simple and convenient.

[0034] like Figure 5As shown, the cleaning assembly 32 includes a sliding plate 320 slidably disposed within the slide groove b311. Slider blocks 321 are fixedly connected to both sides of the sliding plate 320, and a brush 322 is provided at the bottom of the sliding plate 320. After prolonged use, the micro-electrostatic dust collection screen 222 needs to have its surface cleaned of adsorbed particles to prevent clogged ducts and maintain its adsorption and purification efficiency. Cleaning is achieved by simply pulling the micro-electrostatic dust collection screen 222 out of the housing 1 using the support plate 310, flipping the screen over, and then moving the sliding plate 320 back and forth along the slide groove b311. The brush 322 on the sliding plate 320 provides convenient and timely cleaning of the micro-electrostatic dust collection screen 222. This simple and efficient cleaning method ensures the smooth operation of the micro-electrostatic dust collection screen 222. The length of the sliding plate 320 is matched to the micro-electrostatic dust collection screen 222, maximizing cleaning efficiency.

[0035] like Figure 1 and Figure 3 As shown, the cleaning assembly 32 also includes a window 323 opened on one side of the housing 1 and a rotating seat 324 fixedly installed above the window 323. A baffle 325 is hinged to the rotating seat 324. The position of the window 323 matches the installation position of the micro electrostatic dust collection screen 222. The size of the window 323 matches the size of the support plate 310 and is larger than the size of the micro electrostatic dust collection screen 222. The baffle 325 is hinged to the rotating seat 324. When it is necessary to clean the micro electrostatic dust collection screen 222, simply flip the baffle 325 upwards to easily bring the micro electrostatic dust collection screen 222 out of the housing 1 through the window 323 for cleaning via the support plate 310. After the micro electrostatic dust collection screen 222 is cleaned and put back into the housing 1, flip the baffle 325 down to reset it to close the window 323, preventing particles that have not yet been adsorbed from entering the room through the window 323 and affecting the indoor air quality. Example 2

[0036] like Figure 4 As shown, components that are the same as or corresponding to those in Embodiment 1 are marked with the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that a pull ring 225 is provided on the micro electrostatic dust collection screen 222. The pull ring 225 makes it easier and less strenuous to flip the micro electrostatic dust collection screen 222 and pull it out of the housing 1.

[0037] Work process

[0038] When the air conditioner is turned on, the airflow sensor 231 senses the airflow and sends a signal to the controller 230. The controller 230 then sends signals to the regulated power supply a210 and the regulated power supply b220 to control their operation. The regulated power supply a210 powers the negative ion generator 212, and the regulated power supply b222 powers the micro electrostatic dust collection screen 222. The negative ion generator 212 controls the carbon brush 211 to discharge, charging the particulate matter carried in the blown air with negative electrons. The charged particulate matter is then adsorbed by the energized micro electrostatic dust collection screen 222, thus completing the process of removing bacteria. For the purification of harmful substances such as viruses, when it is necessary to clean the micro electrostatic dust collection screen 222, simply flip the baffle 325 upwards, and then use the support plate 310 to bring the micro electrostatic dust collection screen 222 out of the housing 1 through the window 323. Next, flip the micro electrostatic dust collection screen 222 over, and then move the slide plate 320 back and forth along the slide groove b311. The brush 322 set on the slide plate 320 effectively and promptly cleans the micro electrostatic dust collection screen 222. After the micro electrostatic dust collection screen 222 is cleaned, put it back into the housing 1, flip the baffle 325 down to reset it, and close the window 323.
