Description

Technical Field

[0001] The present invention belongs to the technical field of air purifiers, and particularly relates to an electrostatic dust removal device and an air purifier. Background Art

[0002] An air purifier refers to a device designed to improve the cleanliness of indoor air and capable of adsorbing, decomposing or transforming various air pollutants. By setting up an air purifier, various pollutants in indoor air can be effectively removed, including particulate matter, harmful gases, bacteria and viruses, etc., improving indoor air quality and creating a healthier and more comfortable living environment. It is widely used, for example, in various indoor environments such as homes and offices. An electrostatic dust removal air purifier separates dust-containing gas by electricity when it passes through a high-voltage electrostatic field. After dust particles combine with negative ions and carry negative charges, they tend to discharge and deposit on the anode surface. That is, in a strong electric field, air molecules are ionized into positive ions and electrons. When electrons run towards the positive electrode, they encounter dust particles, making the dust particles carry negative charges and adsorbing them to the positive electrode for collection.

[0003] When the existing electrostatic dust removal air purifier is actually in use, both the inside and outside of the machine body need to be cleaned regularly. Generally, the outside of the electrostatic dust removal air purifier is ventilated through holes, making it inconvenient to clean the dust inside the holes. At the same time, when cleaning the electrostatic dust removal component, dust will fall off from the electrostatic dust removal component and scatter into the room, causing secondary pollution to the room.

[0004] Therefore, there is an urgent need to provide an electrostatic dust removal device and an air purifier to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an electrostatic dust removal device and an air purifier.

[0006] The technical solution adopted to solve the above technical problem is: an electrostatic dust removal device and an air purifier, including a mounting base, a cleaning mechanism is arranged at the top end of the mounting base, an installation box is arranged at the top end of the cleaning mechanism, a dust removal fan is fixedly installed at the top end of the installation box, a protective grille is fixedly installed at the top end of the dust removal fan, an electrostatic dust removal mechanism is arranged inside the cleaning mechanism, and a moving mechanism is arranged at the bottom end of the mounting base.

[0007] Preferably, the cleaning mechanism includes a threaded bottom ring threadedly installed on the inner wall of the mounting base, a ventilation connecting rod is fixedly installed on the inner wall of the threaded bottom ring, and a threaded top ring is fixedly installed on the outside of the ventilation connecting rod.

[0008] Through the above technical solution, the threaded bottom ring, the ventilation connecting rod and the threaded top ring together constitute the body of the air purifier. The air purifier is ventilated through the gaps between the ventilation connecting rods. The two ends of the body are respectively threadedly connected to the mounting base and the mounting box.

[0009] Preferably, a foldable garbage bag is placed on the top of the mounting base, a sliding lifting ring is fixedly mounted on the top of the foldable garbage bag, and an outer surface of the sliding lifting ring is slidably connected to the inside of the ventilation connecting rod.

[0010] Through the above technical solution, the foldable garbage bag includes two parts: a bottom and a folding part. The bottom has strong tear resistance, and the folding part is a structure similar to a bellows, and the folding part is lifted by a sliding lifting ring.

[0011] Preferably, a rotating cleaning brush is fixedly mounted on the outer surface of the sliding lifting ring, and a lifting handle is vertically rotatably mounted on the top of the sliding lifting ring, and the outer surfaces of the rotating cleaning brush and the lifting handle are tightly fitted with the ventilation connecting rod.

[0012] Through the above technical solution, the lifting handle is rotated and twisted out of the ventilation connecting rod by hand, and the sliding lifting ring is driven to rise by the lifting handle. The sliding lifting ring cleans the gap of the ventilation connecting rod through the rotating cleaning brush.

[0013] Preferably, the electrostatic dust removal mechanism includes an electrostatic dust removal component embedded in the top of the mounting base, an activated carbon filter is embedded in the outer surface of the electrostatic dust removal component, and a docking ring with one end penetrating and extending into the interior of the mounting box is fixedly installed on the top of the electrostatic dust removal component.

[0014] Through the above technical solution, the activated carbon filter can filter animal hair, flying catkins and larger pollutants, and can also filter volatile gases in the air. The electrostatic dust removal component allows the particles to be positively charged, and then the particles are quickly adsorbed by the negative charge. At the same time, high-voltage static electricity is released to instantly kill viruses and bacteria on the particles, eliminating the source of infection.

[0015] Preferably, two conductive holes are provided at the top of the docking ring, and a conductive plug rod is fixedly mounted on the inner top wall of the installation box, and the conductive plug rod is electrically connected through the conductive holes.

[0016] Through the above technical solution, the conductive rod is inserted into the conductive hole, so that the electrostatic dust removal component is energized through the conductive hole of the docking ring.

[0017] Preferably, the moving mechanism comprises a mounting shell fixed to the bottom end of the mounting base, a double-headed motor is fixedly mounted on the inner bottom wall of the mounting shell, and an output shaft of the double-headed motor is fixedly connected to two worm shafts via a coupling.

[0018] Through the above technical solution, the power supply built into the installation shell provides power for the double-headed motor, and the double-headed motor drives the two worm shafts to rotate.

[0019] Preferably, two pulley shafts are rotatably installed inside the installation shell, worm wheels are fixedly installed on the outer surfaces of the two pulley shafts, and the outer surfaces of the two worm wheels are respectively meshed with the outer surfaces of the two worm shafts.

[0020] Through the above technical solution, the two worm shafts respectively drive the pulley shafts to rotate through the worm wheels.

[0021] Preferably, a thick and thin rubber belt is frictionally connected to the outer surfaces of the two pulley shafts. Half of the thick and thin rubber belt is a thick belt and the other half is a thin belt. Movable wheels are fixedly installed at both ends of the two pulley shafts.

[0022] Through the above technical solution, the size of the movable wheel is larger than the outer contour of the thin belt, and the size of the movable wheel is smaller than the outer contour of the thick belt, so that usually the air purifier moves through the movable wheel, and the movable wheel can be adjusted in angle, and thus can turn and move. When it is necessary to be fixed at a certain specific position for use, the pulley shaft drives the top thick belt and the bottom thin belt of the thick and thin rubber belt to be swapped, so that the thick belt supports the air purifier.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) By providing a cleaning mechanism and an electrostatic dust removal mechanism, the present invention changes the holes outside the body of the air purifier to a vertical rod design, so that the rotating cleaning brush can conveniently carry out the cleaning work. In addition, the electrostatic dust removal component is designed to be covered by a foldable garbage bag to prevent dust from scattering during cleaning and avoid secondary pollution to the room. This structure not only improves the cleaning efficiency of the device, but also enhances the convenience of use and environmental hygiene;

[0025] (2) By providing a moving mechanism, usually the air purifier can be moved through the movable wheel, so that the user can easily move the device from one position to another without having to lift the entire body with effort. When it is necessary to be fixed at a certain specific position for use, the thick and thin rubber belt will contact the ground to increase the friction force, thereby improving the stability of the air purifier and reducing the risk of damage that may be caused by handling.

Detailed implementation manners

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] As Figures 1 - 6As shown in the figure, an electrostatic dust removal device and an air purifier according to this embodiment include a mounting base 1. A cleaning mechanism 2 is provided at the top of the mounting base 1. The cleaning mechanism 2 includes a threaded bottom ring 201 threadedly installed on the inner wall of the mounting base 1. A ventilation connecting rod 202 is fixedly installed on the inner wall of the threaded bottom ring 201. A threaded top ring 203 is fixedly installed on the outer part of the ventilation connecting rod 202. A folded garbage bag 204 is placed in a fitting manner on the top of the mounting base 1. A sliding and lifting ring 205 is fixedly installed at the top of the folded garbage bag 204. The outer surface of the sliding and lifting ring 205 is slidably connected to the inside of the ventilation connecting rod 202. A rotary cleaning brush 206 is fixedly installed on the outer surface of the sliding and lifting ring 205. A lifting handle 207 is vertically rotatably installed at the top of the sliding and lifting ring 205. The outer surfaces of the rotary cleaning brush 206 and the lifting handle 207 are in close contact with the ventilation connecting rod 202. The threaded bottom ring 201, the ventilation connecting rod 202, and the threaded top ring 203 together form the body of the air purifier. The air purifier ventilates through the intervals between the ventilation connecting rods 202. Both ends of the body are threadedly connected to the mounting base 1 and the mounting box 3 respectively. The folded garbage bag 204 includes a bottom part and a folded part. The bottom part has strong tear resistance to prevent damage to the folded garbage bag 204 when the mounting base 1 rotates. The folded part is a structure similar to a corrugated pipe. Usually, it is folded up to reduce the volume. During use, the folded part is lifted by the sliding and lifting ring 205, so that the folded garbage bag 204 covers the electrostatic dust removal component 601 to prevent dust from scattering during cleaning. The lifting handle 207 can be rotated vertically, which is convenient for putting the sliding and lifting ring 205 into the body. At the same time, the sliding and lifting ring 205 is lifted and lowered by the lifting handle 207, and the sliding and lifting ring 205 cleans the gap of the ventilation connecting rod 202 through the rotary cleaning brush 206.

[0035] As Figure 3 and Figure 5As shown, a mounting box 3 is provided at the top of the cleaning mechanism 2, a dust removal fan 4 is fixedly installed at the top of the mounting box 3, a protective grille 5 is fixedly installed at the top of the dust removal fan 4, an electrostatic dust removal mechanism 6 is provided inside the cleaning mechanism 2, the electrostatic dust removal mechanism 6 includes an electrostatic dust removal component 601 embedded in the top of the mounting base 1, an activated carbon filter 602 is embedded in the outer surface of the electrostatic dust removal component 601, a docking ring 603 with one end penetrating and extending into the interior of the mounting box 3 is fixedly installed at the top of the electrostatic dust removal component 601, two conductive holes 604 are provided at the top of the docking ring 603, a conductive plug rod 605 is fixedly installed on the inner top wall of the mounting box 3, and the conductive plug rod 605 passes through the conductive hole 60 4 are electrically connected, the dust removal fan 4 drives the air to enter from the activated carbon filter 602 and the electrostatic dust removal component 601 through the installation box 3, and is discharged through the protective grille 5. The protective grille 5 prevents debris from falling from the top of the dust removal fan 4. The activated carbon filter 602 filters animal hair, flying catkins and larger pollutants, and can also filter volatile gases in the air. The electrostatic dust removal component 601 allows the particles to be positively charged, and then the particles are quickly adsorbed by the negative charge, and at the same time releases high-voltage static electricity to instantly kill viruses and bacteria on the particles, eliminating the source of infection. The conductive plug 605 is inserted into the conductive hole 604, so that the electrostatic dust removal component 601 is energized through the conductive hole 604 of the docking ring 603.

[0036] like Figure 6As shown in the figure, a moving mechanism 7 is provided at the bottom end of the mounting base 1. The moving mechanism 7 includes a mounting shell 701 fixed to the bottom end of the mounting base 1. A double-headed motor 702 is fixedly installed on the inner bottom wall of the mounting shell 701. The output shafts of the double-headed motor 702 are fixedly connected to two worm shafts 703 through couplings. Two pulley shafts 704 are rotatably installed inside the mounting shell 701. Worms 705 are fixedly installed on the outer surfaces of the two pulley shafts 704. The outer surfaces of the two worms 705 are respectively meshed with the outer surfaces of the two worm shafts 703. A thick and thin rubber belt 706 is frictionally connected to the outer surfaces of the two pulley shafts 704. Half of the thick and thin rubber belt 706 is a thick belt and the other half is a thin belt. Moving wheels 707 are fixedly installed at both ends of the two pulley shafts 704. The size of the moving wheel 707 is larger than the outer profile of the thin belt and smaller than the outer profile of the thick belt. Usually, the air purifier moves through the moving wheels 707, and the moving wheels 707 can be adjusted in angle, and thus can move in a turn. When it is necessary to be fixed at a specific position for use, the built-in power supply in the mounting shell 701 provides power for the double-headed motor 702. The double-headed motor 702 drives the two worm shafts 703 to rotate. The two worm shafts 703 respectively drive the pulley shafts 704 to rotate through the worms 705. The pulley shafts 704 drive the top thick belt and the bottom thin belt of the thick and thin rubber belt 706 to be swapped, so that the thick belt supports the air purifier and lifts the moving wheels 707, thereby improving the stability of the air purifier.

[0037] The working principle of this embodiment is as follows. Usually, the air purifier is moved by the movable wheels 707. When it needs to be fixed at a specific position for use, the built-in power supply in the installation shell 701 provides power for the double-headed motor 702. The double-headed motor 702 drives the two worm shafts 703 to rotate. The two worm shafts 703 respectively drive the pulley shafts 704 to rotate through the worm wheels 705. The pulley shafts 704 drive the top thick belt and the bottom thin belt of the thick and thin rubber belt 706 to be swapped, so that the thick belt supports the air purifier. Start the air purifier. The dust removal fan 4 allows air to enter the air purifier through the gap between the ventilation connecting rods 202. The activated carbon filter screen 602 filters animal hair, flying flocs and larger pollutants. The electrostatic dust removal component 601 makes the particulate matter carry a positive charge, and then the particulate matter is quickly adsorbed by the negative charge. At the same time, high-voltage static electricity is released to instantly kill the viruses and bacteria on the particulate matter, eliminating the source of infection. The purified air is discharged through the installation box 3 and the protective grille 5. The protective grille 5 prevents sundries from falling into the air purifier from the top of the dust removal fan 4. When cleaning the air purifier, remove the installation box 3 from the threaded top ring 203, and the lifting handle 207 can be rotated vertically so that the lifting handle 207 leaks out from between the ventilation connecting rods 202. Manually drive the lifting handle 207 and the sliding lifting ring 205 to rise. The sliding lifting ring 205 cleans the gap of the ventilation connecting rod 202 through the rotary cleaning brush 206. At the same time, the sliding lifting ring 205 lifts the folding part of the folding garbage bag 204 so that the folding garbage bag 204 covers the electrostatic dust removal component 601 to prevent dust from scattering during cleaning. After the air purifier is cleaned, the electrostatic dust removal component 601 is electrically connected to the conductive plug 605 through the conductive hole 604 of the docking ring 603. The ventilation connecting rod 202 is threadedly connected to the installation box 3 through the threaded top ring 203. The sliding lifting ring 205 and the folding garbage bag 204 are reinstalled inside the ventilation connecting rod 202. The ventilation connecting rod 202 is threadedly connected to the installation base 1 through the threaded bottom ring 201 to complete the disassembly and cleaning of the air purifier body.
