Description

Technical Field

[0001] This utility model relates to the technical field of filters, and specifically discloses an annular air filter with a reinforced structure and a reinforcement component. Background Technology

[0002] An air filter is a device used to filter dust, particulate matter, and other pollutants from the air. Air filters are widely used in motor vehicles, homes, offices, medical institutions, industrial production, and other places to help improve air quality and protect people's health.

[0003] The existing annular filter consists of an upper cover, a lower cover, and annular filter paper. Air enters the inner cavity formed by the upper and lower covers through the outer side of the annular filter paper and then exits from the air outlet of the upper or lower cover. The filter element is subjected to the impact force of the air from the inside out, which makes the multi-pleated annular filter paper prone to deformation, resulting in uneven arrangement of the multi-pleated annular filter paper, thus affecting the filtration efficiency. In the long run, it may even cause the filter to fail to function properly and become unusable. Therefore, a solution is needed to address the problem of poor impact resistance of annular air filters. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an annular air filter and a reinforcement component with a reinforced structure.

[0005] On the one hand, this utility model discloses an annular air filter with a reinforced structure, which adopts the following technical solution:

[0006] An annular air filter with a reinforced structure includes an annular folded filter paper, a top cover, and a base. The top cover, the base, and the interior of the annular folded filter paper form an inner cavity. The top cover has an air outlet communicating with the inner cavity. A reinforcing component is provided in the inner cavity. The reinforcing component includes a central tube and a reinforcing member disposed on the outer surface of the central tube. The reinforcing member has several grooves, and the peaks of the annular folded filter paper's inner cavity extend into the grooves.

[0007] Preferably, the central tube includes a plurality of annular transverse reinforcing ribs spaced apart and coaxial, and a plurality of vertical reinforcing ribs spaced apart around the annular transverse reinforcing ribs.

[0008] Preferably, the reinforcing member is a plurality of serrated protrusions disposed on an annular transverse reinforcing rib, with the groove formed between adjacent protrusions.

[0009] Preferably, the reinforcing member is integrally formed on the annular transverse reinforcing rib.

[0010] Preferably, the groove is provided with an elastic pad layer.

[0011] Preferably, the cross-section of the groove is any one of a triangle, rectangle, trapezoid, or arc.

[0012] Preferably, the depth of the groove is 1~3mm and the width of the opening is 2~5mm.

[0013] On the other hand, this utility model discloses a reinforcement component for an air filter, which is the reinforcement component described above.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] This invention incorporates a reinforcing assembly, including a central tube and reinforcing components, installed within the inner cavity of the annular pleated filter paper. When the annular pleated filter paper is impacted by air flowing from the outside to the inside, the central tube provides support, preventing the filter paper from concave. The grooves in the reinforcing components position the folds of the annular pleated filter paper, preventing deformation due to lateral movement. The combination of the central tube and the reinforcing components ensures that the annular pleated filter paper is less prone to deformation and damage during use, extending its service life and contributing to stable filtration performance.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] This embodiment discloses an annular air filter with a reinforced structure, including annular folded filter paper 1, a top cover 2, and a base 3. The annular folded filter paper 1 is formed by folding filter paper in a Z-shape and attaching it to both ends in annular shapes. The sides of the annular folded filter paper 1 form a serrated shape with alternating peak and valley folds. The top cover 2, the base 3, and the interior of the annular folded filter paper 1 form an inner cavity. The top cover 2 has an air outlet communicating with the inner cavity. Air enters the inner cavity from the outside of the annular filter paper and then exits from the air outlet. To avoid deformation of the annular folded filter paper 1 due to air impact, as an improvement, a reinforcing component 4 is provided in the inner cavity of the annular folded filter paper 1. The reinforcing component 4 includes a central tube and a reinforcing member disposed on the outer surface of the central tube. The central tube is hollowed out, and the reinforcing member has several grooves 44. The peak folds of the inner cavity of the annular folded filter paper 1 extend into the grooves 44.

[0022] By adopting the above design, the central tube supports the annular pleated filter paper 1 when it is impacted by air from the outside to the inside. In addition, the groove 44 of the reinforcement also positions the peaks of the annular pleated filter paper 1, making it less prone to deformation due to left and right shaking. The cooperation between the central tube and the reinforcement makes the annular pleated filter paper 1 less prone to deformation and damage during use, extending its service life and also helping to stabilize the filtration effect.

[0023] As a preferred embodiment, the central tube includes several spaced-apart and coaxial annular transverse reinforcing ribs 41, and several spaced-apart vertical reinforcing ribs 42 arranged around the annular transverse reinforcing ribs 41. By adopting the above design, while ensuring the structural stability of the reinforced component, the hollowing effect is better, resulting in smoother airflow and improved filtration efficiency.

[0024] As a preferred embodiment, the reinforcement consists of several serrated protrusions 43 disposed on the annular transverse reinforcing rib 41. The protrusions 43 protrude beyond the vertical reinforcing rib 42, and grooves 44 are formed between adjacent protrusions 43. The grooves 44 and protrusions 43 are alternately arranged to engage and match the shape of the annular folded filter paper 1, which helps to improve the positioning stability of the annular folded filter paper 1. In addition, the reinforcement can be integrally formed on the annular transverse reinforcing rib 41, and the integral structure is easier to manufacture.

[0025] As a preferred embodiment, an elastic pad 45 is provided in the groove 44. The material of the elastic pad 45 can be silicone. By adding the elastic pad 45, direct friction between the annular folded filter paper 1 and the protrusion 43 can be effectively avoided during installation or operation. The elastic pad 45 is filled in the micro gap between the annular folded filter paper 1 and the groove 44 under pressure. The assembly tolerance is supplemented by continuous elastic deformation, thereby further improving the support and reinforcement effect of the folded annular filter paper 1.

[0026] As a preferred embodiment, the groove 44 has a triangular cross-section. In other embodiments, it can also be rectangular, trapezoidal, or arc-shaped. The triangular groove 44 structure provides better interlocking and reinforcement for the annular pleated filter paper 1. In addition, the depth of the groove 44 is 1~3mm, and the width of the opening is 2~5mm, which is suitable for the size of common annular pleated filter paper 1 models.

[0027] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
