The pre-filter belt has a front air section and an air outlet section. The air outlet section is arranged adjacent to the filter element. The driving component outputs power to drive the transmission gear to rotate, thereby driving the first transmission belt, the second transmission belt and the pre-filter belt to rotate synchronously. A scraping component is fixedly mounted on the windward or air outlet portion of the pre-filter belt. As the pre-filter belt rotates, the scraping component is used to scrape off impurities from the pre-filter belt. The receiving chamber, located at the bottom of the pre-filter belt, is used to collect impurities scraped off by the scraper.

[0006] In the pre-filtration structure of the filter element as described above, the receiving chamber has no contact with the filter element at the adjacent location, but has at least one contact line with the side away from the filter element.

Detailed Implementation

[0018] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0019] Reference Figures 1 to 5 A filter cartridge pre-filtration structure includes: a first transmission belt 1; The second transmission belt 2 is arranged parallel to the first transmission belt 1; The transmission gear 31 is connected to the first transmission belt 1 and the second transmission belt 2 in a transmission connection. The drive component 32 has its output end connected to the transmission gear 31. The pre-filter belt 4 has its two edges fixed to the first transmission belt 1 and the second transmission belt 2 respectively. The pre-filter belt 4 has a front air section 41 and an air outlet section 42. The air outlet section 42 is arranged adjacent to the filter element 5. The driving member 32 outputs power to drive the transmission gear 31 to rotate, thereby driving the first transmission belt 1, the second transmission belt 2 and the pre-filter belt 4 to rotate synchronously. The scraping member 61 is fixedly mounted on the windward part 41 or the air outlet part 42 of the pre-filter belt 4. As the pre-filter belt 4 rotates, the scraping member 61 is used to scrape off the impurities of the pre-filter belt 4. The receiving chamber 62, located at the bottom of the pre-filter belt 4, is used to collect the impurities scraped off by the scraper 61.

[0020] The pre-filter belt 4 is located on one side of the filter element 5 to pre-filter the air entering the filter element 5. Figure 2 The arrows in the diagram indicate the direction of airflow, thus reducing the frequency of cleaning and replacing the filter element 5. When impurities accumulate on the windward side 41 of the pre-filter belt 4, the drive unit 32 outputs power to drive the first transmission belt 1 and the second transmission belt 2 to rotate synchronously, thereby driving the pre-filter belt 4 to rotate. At the same time, the scraper 61 scrapes off the impurities accumulated on the surface of the pre-filter belt 4 and scrapes the impurities into the receiving chamber 62, thus cleaning the pre-filter belt 4.

[0021] Specifically, the rotation axis of the pre-filter belt 4 is defined as the first horizontal line B. Along the first horizontal line B, the lengths of the scraper 61 and the receiving chamber 62 are both longer than the width of the pre-filter belt 4, ensuring that the scraper 61 can completely scrape off the impurities on the pre-filter belt 4, and that all the impurities scraped off the pre-filter belt 4 can fall into the receiving chamber 62.

[0022] In one embodiment, the receiving chamber 62 has no contact with the filter element 5 at its adjacent location, but has at least one contact line with the side away from the filter element 5. Compared to point contact between the receiving chamber 62 and the filter element 5, the line contact method ensures that impurities at the pre-filter belt 4 can be completely scraped off, improving the scraping effect.

[0023] Specifically, the contact line is parallel to the rotation axis of the pre-filter belt 4.

[0024] It is understandable that if the receiving chamber 62 and the filter element 5 are in surface contact, it means that there are several contact lines between the receiving chamber 62 and the filter element 5.

[0025] In one embodiment, the scraper 61 is fixed to the side of the receiving chamber 62 away from the filter element 5, the scraper 61 matches the arc shape of the pre-filter belt 4, and the scraper 61 is attached to the bottom of the pre-filter belt 4.

[0026] It is understood that the scraper 61 is in surface contact with the pre-filter belt 4. This surface contact allows the scraper 61 to fit more fully against the pre-filter belt 4. The friction between the scraper 61 and the pre-filter belt 4 is relatively large, which helps to loosen and remove dust, dirt and other contaminants attached to the surface of the pre-filter belt 4.

[0027] In one embodiment, the scraper 61 is provided with a cloth brush 63 on the side facing the pre-filter belt 4, the cloth brush 63 being used to scrape off hair adhering to the surface of the pre-filter belt 4.

[0028] Understandably, the pre-filter belt has a filtering function, and its surface is covered with numerous micropores. The bristles of the brush are relatively soft and have a certain degree of elasticity, which can penetrate into various micropores and improve the cleaning effect on the pre-filter belt 4.

[0029] In one embodiment, a first fixing plate 11 is provided on the side of the first transmission belt 1 away from the second transmission belt 2, and a second fixing plate 21 is provided on the side of the second transmission belt 2 away from the first transmission belt 1. The first fixing plate 11 is used to fix the position of the first transmission belt 1, and the second fixing plate 21 is used to fix the position of the second transmission belt 2. This can prevent the pre-filter belt 4 from detaching from the first transmission belt 1 and the second transmission belt 2 during rotation, thus affecting the pre-filtering effect.

[0030] In one embodiment, the system further includes a first rotating shaft 71 and a second rotating shaft 72. The pre-filter belt 4 is sleeved on the first rotating shaft 71 and the second rotating shaft 72. The two ends of the first rotating shaft 71 and the second rotating shaft 72 are rotatably connected to the first fixing plate 11 and the second fixing plate 21, respectively. The transmission gear 31 is fixed to one end of the first rotating shaft 71, and a second transmission gear 33 is fixed to the end of the first rotating shaft 71 away from the transmission gear 31. The second transmission gear 33 is connected to the second transmission belt 2.

[0031] The first rotating shaft 71 and the second rotating shaft 72 serve as the structure supporting the pre-filter belt 4, and also transmit the power of the drive component 32 to the second transmission gear 33 through the first rotating shaft 71, thereby driving the first transmission belt 1 and the second transmission belt 2 to rotate synchronously.

[0032] In one embodiment, a primary transmission gear 34 is connected to the output end of the drive member 32. The drive member 32 is located on the side of the filter element 5 facing away from the pre-filter belt 4. A secondary transmission gear 35 is connected between the primary transmission gear 34 and the transmission gear 31.

[0033] The drive unit 32 is located on the side opposite to the pre-filter belt 4, and the power output of the drive unit 32 is transmitted through the secondary transmission gear 35, instead of being located at the edge of the pre-filter belt 4; this design helps to reduce the overall volume of the filter element pre-filter structure and reduce the floor space occupied.

[0034] Reference Figure 5 In one embodiment, the roller diameter of the first rotating shaft 71 is larger than the tip circle diameter of the second transmission gear 33 and the transmission gear 31. The first rotating shaft 71 and the first fixed plate 11 together restrict the rotation path of the first transmission belt 1, and the second rotating shaft 72 and the second fixed plate 21 together restrict the rotation path of the second transmission belt 2. This ensures that the relative positions of the first fixed plate 11, the first rotating shaft 71, the second fixed plate 21, the second transmission gear 33, and the transmission gear 31 are stable, preventing the pre-filter belt 4 from shifting when the driving member 32 drives the pre-filter belt 4 to rotate, thus affecting the pre-filtering effect, and preventing changes in the relative position of the scraping member 61 and the pre-filter belt 4, which would affect the impurity removal effect.

[0035] In one embodiment, the second rotating shaft 72 has the same structure as the first rotating shaft 71.

[0036] Reference Figure 2 An air purifier, comprising: Casing 100; At least one air inlet 101 is provided on the outer casing 100; At least one air outlet 102 is provided on the outer casing 100; At least one fan 103 is disposed between any one of the air inlets 101 and any one of the air outlets 102; At least one filter element 5 is disposed between any one of the air inlets 101 and any one of the fans 103; At least one filter pre-filter structure 104 is disposed between any one of the air inlets 101 and any one of the filter elements 5, for pre-filtering the air entering the filter element 5.

[0037] Specifically, the air purifier is provided with two air inlets 101 and one air outlet 102. Correspondingly, each of the two air inlets 101 is provided with a filter pre-filtration structure 104, and each of the filter pre-filtration structures is provided with a filter element 5 on one side.

[0038] Specifically, the air purifier has an air inlet 101 and an air outlet 102. Along the direction of air flow, the air inlet 101, the filter pre-filtration structure 104, the filter element 5, the fan 103, and the air outlet 102 are arranged in sequence.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
