Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and more specifically, to a wide-spacing air purifier. Background Technology

[0002] An air purifier is a device that can adsorb, decompose, or transform various air pollutants (such as PM2.5, dust, pollen, odors, formaldehyde, bacteria, allergens, etc.) to effectively improve air cleanliness. It is mainly used in indoor environments such as homes, offices, and commercial spaces, and improves air quality through technologies such as filtration and adsorption. A wide-spacing purifier, on the other hand, is a purifier that improves purification efficiency by increasing the intake area with the air.

[0003] The air purifier disclosed in Chinese Utility Model Patent Publication No. CN222865147U includes a housing, an air outlet grille, a filter component, and a fan assembly. The housing has an air inlet and an air outlet; the air outlet grille is located at the air outlet; the filter component is located at the air inlet; the fan assembly is located inside the housing and drives gas to enter the housing through the air inlet, flow through the filter component and the air outlet grille, and then exit the housing through the air outlet. The air outlet grille includes a frame, a mounting portion, and an air outlet portion; the mounting portion is located within the frame; there are multiple air outlet portions arranged along the inner circumference of the frame, with the first end of each air outlet connected to the mounting portion and the second end connected to the frame; wherein, along the axial direction of the fan assembly, the width of the air outlet portion increases from the side closer to the inside of the housing towards the side closer to the outside of the housing. This utility model, through the design of the air outlet portion shape, utilizes a teardrop-shaped design to reduce the resistance encountered by the airflow during discharge, thereby reducing the noise of the exhaust.

[0004] Leftover food is a common problem in the catering industry. Furthermore, during the mixing and accumulation of various materials, poor ventilation and microbial fermentation can produce foul odors. This not only attracts flies and mosquitoes, affecting food hygiene, but also creates an unpleasant smell and makes cleaning difficult. Therefore, wide-spacing air purifiers are needed to remove these odors. However, existing wide-spacing air purifiers, after inhaling foul odors and filtering them through the air filter, directly expel them. This results in poor filtration and reduces the effectiveness of the air purifier. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a wide-spacing air purifier. The technical problem to be solved by the present invention is that in the process of use, the odorous air inhaled by the existing wide-spacing air purifier is directly discharged after being filtered by the air filter. This makes it difficult for the odorous air to be fully retained and filtered in the wide-spacing air purifier, resulting in poor filtration effect and thus affecting the use effect of the wide-spacing air purifier.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wide-spacing air purifier, comprising a wide-spacing air purifier body and flow channels; the wide-spacing air purifier body includes a casing, an air outlet device, an air filter, and a filter plate; the casing has a mesh structure; the air outlet device is fixed to the top surface of the casing; the air filter is detachably mounted on the top wall of the casing via bolt A; the filter plate is detachably mounted on the top wall of the casing via bolt B, and the air filter is located inside the filter plate; a plurality of flow channels are arranged in a ring array within the filter holes of the filter plate.

[0007] As a further aspect of the present invention: the flow channel has a spiral arc structure, and the cross-section of the flow channel has an arc shape.

[0008] As a further aspect of the present invention, it also includes a scraping component; the scraping component is arranged on the filter plate.

[0009] As a further aspect of the present invention: the scraping assembly includes a transmission rod, blades, a connecting plate, a scraping plate, a guide groove, and a collection box; the transmission rod is rotatably connected to the bottom wall of the machine body via a rotating shaft; a plurality of blades are fixedly arranged in a ring array on the circumferential surface of the transmission rod, and the blades are inclined; a plurality of connecting plates are fixedly arranged in a ring array on the circumferential surface of the transmission rod, and the connecting plates are located below the air filter and the filter plate; the scraping plate is fixedly connected to the end of the connecting plate away from the transmission rod; a guide groove is provided on the scraping plate; the collection box is connected to the scraping plate via a limiting component.

[0010] As a further aspect of the present invention: the guide groove is a right-angled trapezoidal structure with a smaller top and a larger bottom, and the inclined direction of the guide groove is opposite to the inclined direction of the blade.

[0011] As a further aspect of the present invention: the scraping component further includes a guide block; the guide block is fixed to the scraping plate.

[0012] As a further aspect of the present invention: the guide block includes a fixing part, a contact part, and a guiding part; the fixing part is fixed to the scraper plate.

[0013] As a further aspect of the present invention: the contact portion is an arc-shaped structure and contacts the outer circumferential surface of the filter plate; the guide portion is an inclined structure and communicates with the guide groove.

[0014] As a further embodiment of the present invention: the limiting component includes a moving groove, a moving block, a receiving groove, a limiting groove, a limiting block, a moving rod, and a spring; the scraping plate has a moving groove; the moving block is slidably inserted into the moving groove and fixedly connected to the collection box; the moving groove has a receiving groove; the moving block has a limiting groove; the limiting block is slidably disposed in the receiving groove, and the limiting block and the limiting groove are inserted into each other; the moving rod is fixedly disposed on the limiting block, and the end of the moving rod extends to the outside through the receiving groove; the spring is sleeved on the moving rod, and the two ends of the spring are fixedly connected to the inner wall of the receiving groove and the limiting block, respectively.

[0015] As a further aspect of the present invention: the movable block is a T-shaped structure with a larger upper part and a smaller lower part.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by setting a flow channel, first moves the wide-spacing purifier body to a suitable position using casters, then activates the blower in the air outlet device. This allows the odor around the purifier body to enter the body through the air inlet mesh, enabling the filter plate to filter particulate matter in the odor. Furthermore, because the flow channel has a spiral arc structure, it can increase the retention time of odor on the filter plate and improve the filtration effect. The odor filtered by the filter plate is then filtered by the air filter to remove micron-sized impurities, and finally discharged by the blower in the air outlet device. Compared with the prior art, this invention has a reasonable structural design. By extending the flow path of odor on the filter plate, it not only allows the odor to be fully retained and filtered within the wide-spacing purifier body, resulting in a better filtration effect, but also slows down the odor transmission speed, lowering the odor's temperature and thus carrying away the heat generated by the wide-spacing purifier body, thereby assisting in the heat dissipation of the wide-spacing purifier body.

[0018] 2. This invention, by setting up a scraping component, causes the blower on the air outlet device to cause the gas to impact the blades during operation. This causes the transmission rod to rotate within the machine body via the rotating shaft, which in turn causes the connecting plate to rotate the scraping plate. The scraping plate can scrape the particulate impurities adhering to the outer circumference of the filter plate. Since the guide groove is a right-angled trapezoidal structure with a smaller top and a larger bottom, the particulate impurities can fall into the collection box along the inclined surface of the guide groove, thereby reducing the number of times the filter plate needs to be disassembled and cleaned, and ensuring the filtration effect of the filter plate.

[0019] 3. By setting a guide block, the present invention will cause the guide block to rotate when the scraping plate rotates. Since the contact part has an arc-shaped structure and contacts the outer circumferential surface of the filter plate, it can avoid the accumulation of particulate impurities on the outer circumferential surface of the filter plate. Furthermore, since the guide part has an inclined structure and is connected to the guide groove, it can guide the particulate impurities adhering to the outer circumferential surface of the filter plate into the guide groove, thereby improving the scraping and cleaning effect on the filter plate.

[0020] 4. This invention, by setting a limiting component, allows for the treatment of particulate impurities in the collection box. First, the machine body is disassembled. Then, by pressing the moving rod, the moving rod moves, causing the limiting block to slide within the receiving groove and the limiting slot. This causes the spring to stretch until the side of the limiting block contacts the inner wall of the receiving groove. At this point, the limiting block moves out of the limiting slot. Then, the collection box is moved horizontally, causing the moving block to slide within the moving slot until it moves out of the moving slot. This allows for the treatment of particulate impurities in the collection box. The pressing method not only ensures a more stable connection between the limiting block and the limiting slot through the spring's elasticity but also prevents excessive compression of the spring, thus reducing its service life. The moving block has a T-shaped structure, wider at the top and narrower at the bottom, which restricts the vertical direction of the collection box, while the connection between the limiting block and the limiting slot restricts the horizontal direction of the collection box.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, the present invention provides a wide-spacing air purifier, including a wide-spacing air purifier body 1 and a flow channel 2; the wide-spacing air purifier body 1 includes a body 101, an air outlet device 102, an air filter 103, and a filter plate 104; the body 101 has a mesh structure; the air outlet device 102 is fixed to the top surface of the body 101, and a blower is installed inside the air outlet device 102; the air filter 103 is detachably installed on the inner top wall of the body 101 by bolt A, and the air filter 103 is made of fine fiber material. The filter plate 104 is detachably mounted on the inner top wall of the body 101 by bolt B, and the air filter 103 is located inside the filter plate 104; nine flow channels 2 are arranged in a ring array inside the filter holes of the filter plate 104; the flow channels 2 have a spiral arc structure and an arc-shaped cross-section; the bottom surface of the air filter 103 and the filter plate 104 is lower than the bottom surface of the air intake screen of the body 101 to prevent particulate impurities from entering the air filter 103 through the gap between the filter plate 104 and the body 101.

[0034] This invention, by setting a flow channel 2, first moves the wide-spacing purifier body 1 to a suitable position using casters, then activates the blower in the air outlet device 102. This allows the odor surrounding the wide-spacing purifier body 1 to enter the body 101 through the air inlet mesh, enabling the filter plate 104 to filter particulate matter in the odor. Furthermore, because the flow channel 2 has a spiral arc structure, it can increase the retention time and filtration effect of the odor on the filter plate 104. The odor filtered by the filter plate 104 is then filtered by the air filter 103 to remove micron-sized impurities, and finally discharged by the blower in the air outlet device 102. Compared with the prior art, this invention has a reasonable structural design. By extending the flow path of the odor on the filter plate 104, it not only allows the odor to be fully retained and filtered within the wide-spacing purifier body 1, resulting in a better filtration effect, but also slows down the transmission speed of the odor, lowering its temperature and thus carrying away the heat generated by the wide-spacing purifier body 1, thereby assisting in the heat dissipation of the wide-spacing purifier body 1.

[0035] As a preferred embodiment, it also includes a scraping assembly 3; the scraping assembly 3 is arranged on the filter plate 104; the scraping assembly 3 includes a transmission rod 301, blades 302, connecting plates 303, scraping plates 304, guide grooves 305, and a collection box 306; the transmission rod 301 is rotatably connected to the inner bottom wall of the machine body 101 via a rotating shaft; nine blades 302 are fixed in a ring array on the circumferential surface of the transmission rod 301, and the blades 302 have an inclined structure; three connecting plates 303 are arranged in a ring. The array is fixed on the circumferential surface of the transmission rod 301, and the connecting plate 303 is located below the air filter 103 and the filter plate 104; the scraping plate 304 is fixedly connected to the end of the connecting plate 303 away from the transmission rod 301; a guide groove 305 is provided on the scraping plate 304; the collection box 306 is connected to the scraping plate 304 through the limiting component 4; the guide groove 305 is a right-angled trapezoidal structure with a smaller top and a larger bottom, and the inclined direction of the guide groove 305 is opposite to the inclined direction of the blade 302.

[0036] This invention, by setting up a scraping component 3, allows the blower on the air outlet device 102 to cause the gas to impact the blades 302 during operation. This causes the transmission rod 301 to rotate within the machine body 101 via the rotating shaft, which in turn causes the connecting plate 303 to drive the scraping plate 304 to rotate. This allows the scraping plate 304 to scrape the particulate impurities adhering to the outer circumferential surface of the filter plate 104. Since the guide groove 305 has a right-angled trapezoidal structure that is smaller at the top and larger at the bottom, the particulate impurities can fall into the collection box 306 along the inclined surface of the guide groove 305, thereby reducing the number of times the filter plate 104 needs to be disassembled and cleaned, and ensuring the filtration effect of the filter plate 104.

[0037] As a preferred embodiment, the scraping component 3 further includes a guide block 307; the guide block 307 is fixed on the scraping plate 304; the guide block 307 includes a fixing part 3071, a contact part 3072 and a guide part 3073; the fixing part 3071 is fixed on the scraping plate 304; the contact part 3072 has an arc-shaped structure and contacts the outer circumferential surface of the filter plate 104; the guide part 3073 has an inclined structure and communicates with the guide groove 305.

[0038] By setting a guide block 307, when the scraping plate 304 rotates, the guide block 307 will rotate as well. Since the contact part 3072 has an arc-shaped structure and contacts the outer circumferential surface of the filter plate 104, it can prevent particulate impurities from accumulating on the outer circumferential surface of the filter plate 104. Furthermore, since the guide part 3073 has an inclined structure and communicates with the guide groove 305, it can guide the particulate impurities adhering to the outer circumferential surface of the filter plate 104 into the guide groove 305, thereby improving the scraping and cleaning effect of the filter plate 104.

[0039] In a preferred embodiment, the limiting component 4 includes a moving groove 401, a moving block 402, a receiving groove 403, a limiting groove 404, a limiting block 405, a moving rod 406, and a spring 407; the scraping plate 304 has a moving groove 401; the moving block 402 is slidably disposed within the moving groove 401 and fixedly connected to the collection box 306; the moving groove 401 has a receiving groove 403; the moving block 402 has a limiting groove 404; the limiting block 405 is slidably disposed within the receiving groove 403, and the limiting block 405 is inserted into the limiting groove 404; the moving rod 406... Rod 406 is fixed on limiting block 405, and the end of moving rod 406 extends to the outside through receiving groove 403; spring 407 is sleeved on moving rod 406, and the two ends of spring 407 are fixedly connected to the inner wall of receiving groove 403 and limiting block 405 respectively; moving block 402 has a T-shaped structure that is larger at the top and smaller at the bottom; the distance between moving block 402 and the inner wall of machine body 101 is greater than the length of moving block 402; when the side of limiting block 405 contacts the inner wall of receiving groove 403, the side of moving rod 406 away from limiting block 405 is not in receiving groove 403.

[0040] This invention, by setting a limiting component 4, allows for the following process when particulate impurities in the collection box 306 need to be processed: first, the machine body 101 is disassembled; then, by pressing the moving rod 406, it moves, causing the limiting block 405 to slide within the receiving groove 403 and the limiting groove 404. This causes the spring 407 to stretch under pressure until the side of the limiting block 405 contacts the inner wall of the receiving groove 403. At this point, the limiting block 405 moves out of the limiting groove 404. Then, the collection box 306 is moved horizontally, causing the moving block 402 to slide within the moving groove 401. Once the movable block 402 moves out of the movable groove 401, the particulate impurities in the collection box 306 can be processed. By pressing, not only can the elastic force of the spring 407 make the insertion of the limiting block 405 and the limiting groove 404 more stable, but it can also prevent the spring 407 from being excessively squeezed and affecting its service life. Since the movable block 402 has a T-shaped structure that is larger at the top and smaller at the bottom, it can restrict the vertical direction of the collection box 306, while the insertion of the limiting block 405 and the limiting groove 404 can restrict the horizontal direction of the collection box 306.

[0041] The wide-spacing purifier body 1 is a conventional instrument. Its working principle, size, and model are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this invention is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0042] The working principle of this invention is as follows: In use, firstly, the wide-spacing air purifier body 1 is moved to a suitable position using the casters. Then, the blower in the air outlet device 102 is activated, allowing the odor surrounding the wide-spacing air purifier body 1 to enter the body 101 through the air inlet mesh. This allows the filter plate 104 to filter particulate matter in the odor. Furthermore, because the flow channel 2 has a spiral arc structure, it can increase the retention time of odor on the filter plate 104 and improve the filtration effect. The odor filtered by the filter plate 104 is then filtered by the air filter mesh 103 to remove micron-sized impurities, and finally... The filtered odor is discharged by a blower on the air outlet device 102. When the blower is working, the gas impacts the blades 302, causing the transmission rod 301 to rotate within the body 101 via a rotating shaft. This causes the connecting plate 303 to rotate the scraping plate 304, allowing the scraping plate 304 to scrape the particulate impurities adhering to the outer circumference of the filter plate 104. The guide block 307 guides the particulate impurities into the guide groove 305. Since the guide groove 305 has a right-angled trapezoidal structure that is smaller at the top and larger at the bottom, the particulate impurities can be guided along the guide groove. The inclined surface of groove 305 falls into collection box 306 to reduce the number of times filter plate 104 needs to be disassembled and cleaned, thus ensuring the filtration effect of filter plate 104. When it is necessary to treat particulate impurities in collection box 306, first disassemble the machine body 101, then press the moving rod 406 to move it, causing the limiting block 405 to slide in receiving groove 403 and limiting groove 404, causing spring 407 to stretch under force until the side of limiting block 405 contacts the inner wall of receiving groove 403. At this time, limiting block 405 moves out of limiting groove 404, and then moves horizontally. Move the collection box 306 to make the moving block 402 slide in the moving groove 401 until the moving block 402 moves out of the moving groove 401, so that the particulate impurities in the collection box 306 can be processed. After the processing is completed, insert the moving block 402 into the moving groove 401 until the side of the moving block 402 contacts the inner side wall of the moving groove 401. At this time, release the moving rod 406. Under the elastic force of the spring 407, the limiting block 405 will slide in the opposite direction in the receiving groove 403 until the spring 407 returns to its original shape. At this time, the limiting block 405 is inserted into the limiting groove 404.

[0043] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
