Description

Technical Field

[0001] The utility model belongs to the technical field of composite filters, and in particular relates to a composite filter with a cleaning mechanism. Background Art

[0002] Composite filters typically use a combination of multiple filter media to achieve multi-stage filtration. Different filter media can effectively remove impurities of different sizes and types, greatly improving filtration efficiency. The filter element inside an air purifier is a composite filter.

[0003] When the air purifier is purifying the air, the external air flows from the surface of the filter element to the inside of the filter element. The air is purified in this process, and the purified air inside the filter element flows out directly from the upper end of the filter element. The surface of the filter element is mainly used to filter larger impurities in the air, and the filtered dust is easy to adhere to the surface of the filter element. With the long-term use of the air purifier, the dust accumulated on the surface of the filter element will become more and more. This phenomenon will easily lead to a decrease in the circulation rate of air flowing into the filter element. In order to ensure the efficiency of the air purifier, the filter element needs to be frequently removed from the inside of the air purifier and cleaned, which reduces the practicality of the air purifier.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0028] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0029] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0030] See also Figures 1-6 As shown, the utility model is a composite filter with a cleaning mechanism, comprising a support assembly 1, a composite filter assembly 2 is arranged inside the support assembly 1, a cleaning assembly 3 is arranged on the outer surface of the composite filter assembly 2, a driving assembly 4 is arranged inside the support assembly 1, the driving end of the driving assembly 4 is connected to the cleaning assembly 3, and a collecting assembly 5 is arranged at the bottom of the support assembly 1.

[0031] The support component 1 is used to support the composite filter component 2, and the composite filter component 2 is used to filter and purify the air. The driving component 4 is used to drive the cleaning component 3 to rotate on the outer surface of the composite filter component 2 so that the collecting component 5 can collect the dust swept down.

[0032] The air purifier extracts the outside air, and the extracted air passes through the inside of the composite filter component 2, so that the composite filter component 2 filters and purifies the air. At the same time, the driving component 4 drives the cleaning component 3, so that the cleaning component 3 rotates on the outer surface of the composite filter component 2. The rotating cleaning component 3 cleans the dust filtered on the outer surface of the composite filter component 2, and the cleaned dust can fall downward and directly fall into the inside of the collecting component 5.

[0033] The cleaning component 3 is driven by the driving component 4, so that the cleaning component 3 cleans the dust and impurities accumulated on the outer surface of the composite filter component 2, and the cleaned dust falls downward under the guidance of the cleaning component 3 and the action of its own gravity and falls directly into the interior of the collecting component 5. The above arrangement prevents dust from accumulating on the outer surface of the composite filter component 2 when the filter element purifies the air, thereby ensuring the overall air circulation rate of the composite filter component 2, and also avoids the frequent disassembly and cleaning of the filter element when the air purifier is in use, thereby improving the overall practicality of the filter element.

[0034] In one embodiment, the support assembly 1 includes a support plate 101 , the top of the support plate 101 is fixedly connected to a support rod 102 , and the top of the support rod 102 is fixedly connected to a support ring 103 .

[0035] The support plate 101 and the support ring 103 can be connected together by the support rod 102, so that the stability of the support plate 101 and the support ring 103 when supporting the composite filter component 2 can be guaranteed. At the same time, the setting of the support rod 102 makes most of the position between the support plate 101 and the support ring 103 not blocked. This setting ensures the efficiency of air passing through the composite filter component 2.

[0036] In one embodiment, for the above-mentioned composite filter assembly 2, the composite filter assembly 2 includes a filter mesh 201, the filter mesh 201 is fixedly connected between the support plate 101 and the support ring 103, and an activated carbon cartridge 202 is fixedly installed between the support plate 101 and the support ring 103, and the activated carbon cartridge 202 is arranged inside the filter mesh 201.

[0037] When air flows into the interior of the air purifier, the filter 201 can filter the dust and impurities carried in the air. When the filtered air passes through the activated carbon cartridge 202, the activated carbon cartridge 202 adsorbs formaldehyde, toluene and odor in the air, so that the purified air does not have any odor. At the same time, the activated carbon cartridge 202 and the support rod 102 can cooperate to support the filter 201, so that the filter 201 will not be deformed as a whole when filtering the air.

[0038] In one embodiment, for the above-mentioned cleaning component 3, the cleaning component 3 includes a cleaning plate 301, the cleaning plate 301 is arranged on the outside of the filter 201, the cleaning plate 301 is arranged tilted as a whole, and the inner wall of the cleaning plate 301 is fixedly connected with bristles 302, and one end of the bristles 302 is in contact with the outer surface of the filter 201.

[0039] By rotating the cleaning plate 301, the cleaning plate 301 can drive the bristles 302 to rotate on the outer surface of the filter 201, and the rotating bristles 302 clean the dust on the filter 201. At the same time, the bristles 302 occupy a part of the position of the cleaning plate 301. This setting allows the cleaning plate 301 to block the cleaning position of the bristles 302, thereby preventing the cleaned dust from adhering to the outer surface of the filter 201 again under the blowing of subsequent air, so that the dust can fall downward better under the guidance and shielding of the inclined cleaning plate 301.

[0040] In one embodiment, for the above-mentioned drive component 4, the drive component 4 includes a mounting frame 401, the mounting frame 401 is fixedly mounted on the inner wall of the support ring 103, the mounting frame 401 is rotatably connected to a rotating shaft 402, the outer surface of the rotating shaft 402 is fixedly connected to a fan blade 403, the top of the support ring 103 is movably connected to a connecting frame 404, the connecting frame 404 is fixedly connected to the cleaning plate 301, and a connecting rod 405 is fixedly connected between the connecting frame 404 and the rotating shaft 402.

[0041] The purified air can flow out from the support ring 103. At this time, the upward flowing air can blow the fan blades 403, so that the fan blades 403 drive the rotating shaft 402 to rotate on the mounting frame 401, and the rotating rotating shaft 402 drives the cleaning plate 301 to automatically rotate on the outer surface of the filter 201 through the connecting rod 405 and the connecting frame 404, so that the cleaning plate 301 can automatically rotate under the action of the airflow. The above arrangement enables the purified air to be reasonably utilized, so that the filter element as a whole has better environmental protection and energy saving properties; since the connecting frame 404 is directly mounted on the support ring 103, the bristles 302 on the cleaning plate 301 can fit tightly with the filter 201, and this state can be maintained continuously.

[0042] In one embodiment, for the above-mentioned collecting assembly 5, the collecting assembly 5 includes a mounting cylinder 501, the mounting cylinder 501 is arranged on the outside of the supporting plate 101, and the bottom of the supporting plate 101 is fixedly connected with an L-shaped fixing rod 502, one end of the L-shaped fixing rod 502 is fixedly connected to the mounting cylinder 501, and the internal thread of the mounting cylinder 501 is connected with the collecting cylinder 503.

[0043] The L-shaped fixing rod 502 allows the mounting tube 501 to be directly mounted on the outside of the support plate 101. At the same time, there is a moving distance between the mounting tube 501 and the support plate 101. In addition, the bottom of the cleaning plate 301 is in contact with the top of the mounting tube 501, so that the dust swept down can directly pass through the gap between the mounting tube 501 and the support plate 101 under the guidance of the cleaning plate 301 and fall into the interior of the collecting tube 503, so that the collecting tube 503 can collect the swept dust.

[0044] In one embodiment, for the above-mentioned collecting cylinder 503 , a groove 504 is formed at the bottom of the collecting cylinder 503 , and a rotating rod 505 is fixedly connected to the inner wall of the groove 504 .

[0045] By rotating the rotating rod 505, the collecting cylinder 503 can be moved out from the inside of the mounting cylinder 501, making it more convenient to clean the dust collected inside the collecting cylinder 503. At the same time, the rotating rod 505 is set inside the groove 504, so that the bottom of the mounting cylinder 501 can be kept flat. This setting makes it more convenient to install the filter element inside the air purifier.

[0046] Through the above technical solution, 1. the cleaning component 3 is driven by the driving component 4, so that the cleaning component 3 cleans the dust and impurities accumulated on the outer surface of the composite filter component 2, and the cleaned dust falls downward under the guidance of the cleaning component 3 and the action of its own gravity and falls directly into the interior of the collecting component 5. The above arrangement prevents dust from accumulating on the outer surface of the composite filter component 2 when the filter element is purifying the air, thereby ensuring the overall air circulation rate of the composite filter component 2, and also avoiding the occurrence of dust accumulation during the cleaning process. When the air purifier is in use, the filter element is frequently disassembled and cleaned, thereby improving the overall practicality of the filter element; 2. The fan blades 403 are blown by the purified air, so that the fan blades 403 drive the cleaning plate 301 to automatically rotate on the outer surface of the filter 201 through the rotating shaft 402, the connecting rod 405 and the connecting frame 404, so that the cleaning plate 301 can automatically rotate under the action of the airflow. The above arrangement enables the purified air to be reasonably utilized, and also makes the filter element as a whole have better environmental protection and energy saving properties.
