Description

Technical Field

[0001] This utility model relates to the field of air filtration technology, and in particular to a low-resistance, high-efficiency air filter. Background Technology

[0002] Air filters are devices that use porous filter materials to capture dust from a gas-solid two-phase flow. They are used to remove harmful substances such as particulate matter, gaseous pollutants, and microorganisms from the air and are widely used in homes, commercial buildings, industrial sites, and vehicles. They aim to improve indoor air quality, protect human health, and ensure the normal operation of equipment.

[0003] With the rapid development of industrialization and urbanization, air quality has gradually deteriorated, thus increasing the demand for air filters. However, the filter element holder and filter element of existing air filters are not easy to remove. When the dust on the filter element reaches saturation, it will increase the resistance of the air filter and thus affect the air filtration effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-resistance, high-efficiency air filter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-resistance high-efficiency air filter includes a low-resistance high-efficiency air filter body, a slot is provided in the low-resistance high-efficiency air filter body, a filter element bracket is vertically inserted into the slot, a handle is provided on the top of the filter element bracket, a filter element is provided in the filter element bracket, mounting holes are provided on both sides of the upper end of the slot, and two positioning mechanisms are provided on the upper end of the filter element bracket.

[0007] In addition, a preferred structure is that the filter element support has hidden grooves on both sides and a groove on the top, which is connected to the two hidden grooves.

[0008] In addition, a preferred structure is that two sets of sliding grooves are provided on both sides of the groove.

[0009] Furthermore, in a preferred configuration, the positioning mechanism includes a connecting column located within a hidden groove. One end of the connecting column is fixedly mounted on the inner wall of the hidden groove, and a positioning pin is slidably fitted onto the other end of the connecting column and slidably inserted into the mounting hole.

[0010] In addition, a preferred structure is that an L-shaped push plate is provided at the top of one side of the positioning pin head and is movably located in the groove, and sliders are provided on both sides of the L-shaped push plate, with the sliders sliding in the groove.

[0011] In addition, a preferred structure is that the connecting column is fitted with a spring, and the two ends of the spring are fixedly connected to one side of the positioning pin head and the other side of the hidden groove, respectively.

[0012] Furthermore, in a preferred configuration, one end of the low-resistance high-efficiency air filter body is provided with several rotatable guide vanes.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, two L-shaped push plates are simultaneously pushed to move towards each other, thereby disengaging the positioning pin of the positioning mechanism from the mounting hole. Then, the filter element bracket can be removed for filter element replacement or cleaning, facilitating the air filtration of the filter. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-7 A low-resistance high-efficiency air filter includes a low-resistance high-efficiency air filter body 1, a slot 101 is provided in the low-resistance high-efficiency air filter body 1, a filter element bracket 3 is vertically inserted into the slot 101, a handle 32 is provided on the top of the filter element bracket 3, a filter element 31 is provided in the filter element bracket 3, mounting holes 102 are provided on both sides of the upper end of the slot 101, and two positioning mechanisms 4 are provided on the upper end of the filter element bracket 3.

[0025] The filter element support 3 has hidden grooves 33 on both sides and a groove 34 on the top, which is connected to the two hidden grooves 33.

[0026] Meanwhile, two sets of sliding grooves 341 are provided on both sides of the groove 34.

[0027] Furthermore, the positioning mechanism 4 includes a connecting post 43, which is located in the hidden groove 33. One end of the connecting post 43 is fixedly installed on the inner wall of the hidden groove 33, and the other end of the connecting post 43 is slidably fitted with a positioning pin head 41 which is slidably inserted into the mounting hole 102 to limit the installation of the filter element bracket 3.

[0028] Meanwhile, an L-shaped push plate 42 is provided on one side of the top of the positioning pin 41 and is located in the groove 34. Slider 421 is provided on both sides of the L-shaped push plate 42. The slider 421 slides in the groove 341. When the L-shaped push plate 42 is pushed, the slider 421 slides in the groove 341, making the movement of the L-shaped push plate 42 more stable.

[0029] Meanwhile, a spring 44 is provided on the outer sleeve of the connecting column 43. The two ends of the spring 44 are fixedly connected to one side of the positioning pin head 41 and the other side of the hidden groove 33, respectively. The spring 44 springs the positioning pin head 41 into the mounting hole 102.

[0030] Furthermore, the low-resistance high-efficiency air filter body 1 is equipped with several rotatable guide vanes 2 at one end to guide the air.

[0031] In this embodiment, the low-resistance high-efficiency air filter body 1 is placed in a suitable position to filter the air in the space. When the dust collected on the filter element 31 of the low-resistance high-efficiency air filter body 1 reaches saturation and needs to be replaced or cleaned, the two L-shaped push plates 42 at both ends of the filter bracket 3 are simultaneously pushed to move towards each other. The L-shaped push plates 42 will drive the positioning pin head 41 to slide on the connecting post 43 and then leave the mounting hole 102 and enter the hidden groove 33. The positioning pin head 41 will compress the spring 44, and then move upward. Pull the handle 32 to pull the filter element bracket 3 out of the slot 101. Then replace the filter element 31 or clean the filter element 31. At this time, insert the filter element bracket 3 vertically into the slot 101. At the same time, push the two L-shaped push plates 42 to drive the positioning pin head 41 into the hidden groove 33. When the filter element bracket 3 is fully inserted, loosen the two L-shaped push plates 42. Under the elastic action of the spring 44, the positioning pin head 41 slides on the connecting post 43 and is then inserted into the mounting hole 102 to complete the replacement or cleaning of the filter element 31.

[0032] In this invention, two L-shaped push plates 42 are pushed to move towards each other, thereby disengaging the positioning pin 41 of the positioning mechanism 4 from the mounting hole 102. Then, the filter element bracket 3 can be removed to replace or clean the filter element 31, making it easier for the filter to filter the air.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
