Abstract
Description
Technical Field
[0001] This invention relates to the field of air purification, and in particular to an air purifier and purification method that employs positive and negative ion generation. Background Technology
[0002] Traditional air purifiers use fans to draw air in and filters to remove dust, employing a passive adsorption filtration principle. This method only filters dust from the surface, resulting in poor indoor air purification. Therefore, negative ion air purifiers have emerged. These purifiers utilize generated negative ions to purify, remove dust, deodorize, and sterilize the air, thus optimizing the environment. Current negative ion air purifiers typically contain negative ion balls. A fan circulates the air, continuously passing it over the negative ion balls. The released negative ions from these balls purify the air, effectively improving its purification capabilities. However, the negative ion balls need to be replaced periodically.
[0003] For example, Chinese invention patent with publication number 202110555651.7 discloses a negative ion air purifier. This invention discloses a negative ion air purifier, which includes a blocking ring and a pressure-relieving suspension part. The blocking ring is provided with a pressure-relieving suspension part. The blocking ring can ensure that the air purifier is placed away from furniture and walls, preventing a large amount of charged dust around the air purifier from adsorbing onto the wall and causing pollution. After the air purifier is placed away from the wall, the blocking ring can be easily folded. After the blocking ring is folded, the blocking ring and the pressure-relieving suspension part can easily suspend the air purifier at a high place in the room, allowing negative ions to fully combine with the air from a high place, thus purifying the air more fully and effectively.
[0004] Research on the aforementioned negative ion air purifier revealed that it only allows negative ions to fully combine with the air from a high altitude, thus effectively purifying the air; however, this invention cannot adjust the purification based on the amount of air pollution.
[0005] Therefore, we urgently need to invent an air purifier and purification method that uses positive and negative ion generation, which can be adjusted according to the degree of air pollution and effectively reduce the power consumption of the air purifier to solve the above problems. Summary of the Invention
[0006] To address the aforementioned problems, this invention provides an air purifier and purification method employing positive and negative ion generation. By incorporating a shielding mechanism, a filter cleaning mechanism, a purification port closing mechanism, a selective closing mechanism, and a housing, the device integrates functions such as shielding, filter cleaning, and selective purification port closing into one unit. External sensors automatically identify the level of pollution in the external air and selectively close the inlets of one or more negative ion generators based on the pollution level, reducing power consumption. The device automatically cleans dust and impurities from the filter plate, and the collected dust is sucked into an internal dust bag, which can then be manually removed, making the process convenient, quick, and efficient.

[0015] Furthermore, the selective closing mechanism includes: a lead screw E, gear B, gear C, gear D, a transmission structure, a coil spring, a turntable, a coaxial turntable, a rotating disk, a motor C, and a slider;
[0016] The transmission structure is connected to the shaft of the cam via a belt connection. The drive wheel of the transmission structure is connected to the coil spring below.

Detailed Implementation
[0032] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0033] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0034] Examples, such as Figure 1-9 As shown, an air purifier and purification method using positive and negative ion generation includes: a shielding mechanism 1, a filter cleaning mechanism 2, a purification port closing mechanism 3, a selective closing mechanism 4, and a housing part 5;
[0035] The purification port closing mechanism 3 is embedded in the ventilation duct 106 of the shielding mechanism 1. A selective closing mechanism 4 is installed at the bottom of the ventilation duct 106. The transmission structure 405 in the selective closing mechanism 4 is connected to the cam 301 shaft of the purification port closing mechanism 3 by means of a belt connection. The upper shielding mechanism 1 of the shielding mechanism 3 has three sets of sliding baffles 104. The opening of the sliding baffle 104 faces the filter plate cleaning mechanism 2. The shielding mechanism 1, the purification port closing mechanism 3 and the selective closing mechanism 4 are all inside the outer shell 5. The collection box 210 of the filter plate cleaning mechanism 2 is fixed to the outside of the outer shell 501, and the rest are installed inside the outer shell 5.
[0036] When gas enters the shielding mechanism 1, it first passes through the filter plate 107 to filter out dust and impurities in the air, then passes through the negative ion generator 303 in the purification port closing mechanism 3, and then the purified gas is discharged through the outer shell. The selective closing mechanism 4 selectively closes the inlet of one or more negative ion generators according to the degree of air pollution. The filter plate cleaning mechanism 2 can automatically clean the dust and impurities on the filter plate 107.
[0037] Examples, such as Figure 3-4 As shown, the shielding mechanism 1 includes: a ring rack 101, a gear A102, a locking block 103, a sliding baffle 104, a motor A105, a ventilation duct 106, and a filter plate 107.
[0038] The filter plate 107 is mounted on the ventilation duct 106. The ventilation duct 106 has an opening, and above the opening is a groove along the direction of the opening. The groove contains a motor A105. A gear A102 is fixed on the shaft of the motor A105. The gear A102 meshes with the annular rack 101 fixed on the groove. A locking block 103 is fixed to the end of the shaft of the motor A105. The locking block 103 is fixed on the sliding baffle 104. When the filter plate cleaning mechanism 2 is running, the replacement plate 207 can be inserted into the opening of the ventilation duct 106.
[0039] To ensure the airtightness of the ventilation duct 106, when cleaning the filter plate 107, the motor A105 drives the gear A102 to rotate, causing the gear A102 to slide along the ring rack 101, thereby moving the locking block 103, which in turn causes the sliding baffle 104 to slide and block the groove on the ventilation duct 106, thus ensuring the airtightness of the ventilation duct 106.
[0040] Examples, such as Figure 5-6 As shown, the filter plate cleaning mechanism 2 includes: lead screw A201, lead screw B202, lead screw C203, sliding plate 204, cleaning plate 205, lead screw D206, replacement plate 207, clamp 208, motor B209 and collection box 210.
[0041] Lead screw A201 is directly above lead screw B202. A support plate is installed between lead screw A201 and lead screw B202, which supports replacement plate 207. Cleaning plate 205 is above replacement plate 207. Cleaning plate 205 is slidably connected to sliding plate 204 in its middle. Motor B209 is fixed on the top of sliding plate 204. The bottom of the shaft of motor B209 is fixedly connected to cleaning plate 205. Lead screw C203 is also installed on sliding plate 204. The end of replacement plate 207 near housing 501 is connected to clamp 208. Clamp 208 is installed on the connecting plate between the two symmetrical lead screws A201 and the two symmetrical lead screws B202. Lead screw D206 in the up-down direction is installed near housing 501. Collection box 210 is fixed to the outside of housing 501.
[0042] To ensure the filtration capacity of the air purifier's internal filter plate 107, it needs to be cleaned regularly. During cleaning, the upper blocking mechanism 1 is opened, and the clamp 208 of the lead screw A201 pushes the replacement plate 207 into the hole of the ventilation duct 106. Then, the lead screw B202 drives the clamp 208 to pull out the filter plate 107 to be cleaned. By pulling the filter plate 107 below the cleaning plate 205, the lead screw C203 drives the sliding plate 204 to descend, thereby lowering the cleaning plate 205. Since the motor B209 is fixedly mounted on the sliding plate 204, and the shaft of the motor B209 is fixedly connected to the cleaning plate 205, the sliding plate... The moving plate 204 is rotatably connected to the cleaning plate 205, so the motor B209 will drive the cleaning plate 205 to rotate, thereby cleaning the filter plate 107. After cleaning, the filter plate 107 is pushed back, and the replacement plate 207 is pulled back to its original position. After cleaning the first filter plate 107, the entire mechanism is moved to the position of the second filter plate 107 by the lead screw D206, and the filter plate 107 is cleaned by the same operation. After cleaning the three filter plates 107, the replacement plate 207 is cleaned by the same steps. The dust that is cleaned off is sucked into the internal dust bag by the collection box 210, and the dust bag is removed manually.
[0043] Examples, such as Figure 7 As shown, the mechanism for closing the purification port 3 includes: a cam 301, a baffle 302, a negative ion generator 303, and a spring 304;
[0044] The negative ion generator 303 is installed on the outside of the ventilation duct 106. There is a closable gap between the negative ion generator 303 and the baffle 302 located inside the ventilation duct 106. The middle position of the baffle 302 contacts the cam 301. Springs 304 are installed on the upper and lower parts of the baffle 302 respectively.
[0045] The cam 301 drives the baffle 302, which blocks the air inlet of the negative ion generator 303.
[0046] Examples, such as Figure 8 As shown, the selective closing mechanism 4 includes: a lead screw E401, a gear B402, a gear C403, a gear D404, a transmission structure 405, a coil spring 406, a turntable 407, a coaxial turntable 408, a rotating disk 409, a motor C410, and a slider 411;
[0047] The transmission structure 405 is connected to the shaft of the cam 301 via a belt connection. The drive wheel of the transmission structure 405 is connected to the coil spring 406. The motor C410 is mounted on the rotating disk 409. The shaft of the motor C410 is also connected to the coaxial turntable 408 and the turntable 407. The coaxial turntable 408 is below the rotating disk 409, and the turntable 407 is below the coaxial turntable 408 and at the bottom of the mechanism. The rotating disk 409 meshes with the gear C403. The gear B402 is mounted below the gear C403 and is mounted on the lead screw E401 in the same way as the gear C403. The gear B402 meshes with the coaxial turntable 408. The slider 411 is mounted on the lead screw E401, and the gear D404 is fixed on the slider 411.
[0048] Motor C410 drives coaxial turntable 408 to rotate, which in turn drives gear B402 to rotate, which in turn drives lead screw E401 to rotate, which in turn drives slider 411 to move, further driving gear D404 to move downward, so that gear D404 meshes with transmission structure 405. The rotation of coaxial turntable 408 drives turntable 407 to rotate, which in turn drives gear D404 to rotate, which in turn drives transmission structure 405 to rotate, which in turn drives cam 301 to rotate, further opening or closing the corresponding negative ion generator 303 vent. Rotating disc 409 drives gear C403 to rotate, which in turn drives lead screw E401 to reverse, so that gear D404 disengages from transmission structure 405. As gear D404 disengages, coil spring 406 drives transmission structure 405 to reverse, so that cam 301 reverses, and under the action of spring 304, baffle 302 returns to its original position.
[0049] Examples, such as Figure 9 As shown, the outer casing 5 includes: an outer casing 501 and an air outlet 502;
[0050] A collection box 210 is fixed on the outer casing 501, and an air outlet 502 with many ventilation holes is located below the outer casing 501.
