Definitions

  • the utility model belongs to the field of air purification, in particular to an air filtering device.
  • Air purification devices have become more and more important in terms of life, medical treatment, production, etc. with increasing air pollution.
  • air purification equipment on the market usually uses air filtration, that is, the purification machine is provided.
  • Fans and fans are installed on the air outlet of the fan. After the air passes through the filter, dust and impurities are left in the filter to obtain clean air.
  • the filter After the air filter is connected to the fan air outlet, the filter has a certain wind resistance. A certain wind pressure is caused, and when the pressure is too large, the air to be filtered leaks from the gap of the upper and lower connecting shells of the filter, so that the air filtering effect is discounted.
  • the purpose of the utility model is to provide an air filter with a filter sealing ring, which aims to solve the problem that the filter in the prior art is easy to leak the air to be filtered.
  • an air filter with a filter sealing ring comprising a filter outer frame, a net base and a filter paper, wherein the outer edge of the filter is connected with the edge of the net base, the filtering Paper is placed in the outer frame of the filter, and a sealing ring is disposed on the inner wall of the outer frame of the filter, and the upper surface of the sealing ring is bonded to the filter paper.
  • the lower portion of the sealing ring has a downward convexity, and the convex outer surface is in contact with the inner surface of the net base.
  • the upper portion of the sealing ring has a "U" shaped groove.
  • the wind pressure caused by the fan in the filter is blocked by the sealing ring, and the filter outer frame and the net base are The joint is sealed to prevent leakage of the air to be filtered from the joint to ensure air filtration efficiency.
  • Figure 1 is a side cross-sectional view of the product provided by the embodiment of the present invention.
  • FIG. 2 is a schematic exploded view of the product provided by the embodiment of the present invention.

Abstract

L'invention porte sur un filtre à air avec une bague d'étanchéité de filet de filtre, lequel filtre comprend un cadre externe de filtre (2), une base de filet (1), et un morceau de papier-filtre (4). Le bord du cadre externe de filtre (2) est relié au bord de la base de filet (1). Le papier-filtre (4) est disposé à l'intérieur du cadre externe de filtre (2). Une bague d'étanchéité (3) est disposée sur la paroi interne du cadre externe de filtre (2). La surface supérieure de la bague d'étanchéité (3) est attachée au papier-filtre (4). La pression d'air d'un ventilateur dans le filtre subit un effet d'écran par la bague d'étanchéité quand le filtre à air est utilisé, de telle sorte que le cadre externe de filtre et une partie de liaison de la base de filet sont hermétiquement scellés, de façon à empêcher ainsi efficacement une fuite d'air devant être filtré à partir de la partie de liaison, et à assurer ainsi l'efficacité de la filtration d'air.
