Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

An air filter assembly 20 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 3, an air filter assembly 20 according to an embodiment of the present invention includes a housing 200, a filter 300, and a heat exchanging seal 100, the housing 200 having a filter mounting portion 220 and a main body 210.

The filter 300 is mounted to the filter mounting part 220, the filter 300 is for filtering air, the sealing member 100 is ring-shaped, and the sealing member 100 is disposed at one end of the main body 210 adjacent to the filter 300.

It can be understood that the filter mounting portion 220 is disposed at the lower end of the main body 210, the filter mounting portion 220 is a frame, and the filter 300 is embedded in the filter frame, so that the filter 300 can be stably mounted on the main body 210, and the sealing member 100 is sleeved on the main body 210, so as to effectively seal the filter 300 and prevent the filter from falling off.

The sealing member 100 of the air filter assembly 20 according to the embodiment of the present invention is disposed on the main body 210 and close to one end of the filter member 300, so as to provide a good sealing effect for the filter member 300.

Therefore, the air filter assembly 20 according to the embodiment of the utility model has the advantages of good sealing performance and difficult falling off.

In some embodiments, as shown in fig. 1 and 2, the sealing member 100 includes an inner circumferential surface 110, the inner circumferential surface 110 is provided with a mounting groove 160, and the main body 210 is provided with a rib 213, and the rib 213 cooperates with the mounting groove 160 to fix the sealing ring to the main body 210. Therefore, the sealing performance of the seal member 100 is good, and the seal member 100 is not easily detached.

Specifically, as shown in fig. 2-4, the inner circumferential surface 110 of the seal 100 includes a first section 111, a second section 112, and a third section 113. The second segment 112 is located between the first segment 111 and the third segment 113 in a thickness direction (up-down direction in fig. 1) of the seal 100, and a radial dimension of the second segment 112 is larger than a radial dimension of each of the first segment 111 and the third segment 113. That is, the inner circumferential surface 110 of the seal member 100 is a stepped surface, the radial dimension of the second section 112 is larger than that of the first section 111, and the radial dimension of the second section 112 is larger than that of the third section 113, i.e., the second section 112 is a concave surface with respect to the first section 111 and the third section 113.

It should be noted here that the "radial dimension" is to be understood in a broad sense, and for example, the radial dimension of the inner circumferential surface 110 of the seal 100 is a distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the inner circumferential surface 110. Specifically, when the inner peripheral profile of the cross section of the seal 100 is circular, the radial dimension of the inner peripheral surface 110 of the seal 100 is the diameter of the inner peripheral surface 110 of the seal 100.

That is, the "radial dimension of the second section 112 is greater than the radial dimension of the first section 111" means: the distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the second section 112 is larger than the distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the first section 111; "the radial dimension of the second section 112 is greater than the radial dimension of the third section 113" means that: a distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the second section 112 is larger than a distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the third section 113.

As shown in fig. 1, seal 100 also includes a first face 130 and a second face 140, the first face 130 intersecting each of the first section 111 and the second section 112, and the second face 140 intersecting each of the second section 112 and the third section 113. Specifically, the first face 130 is perpendicular to and intersects each of the first segment 111 and the second segment 112, and the second face 140 is perpendicular to and intersects each of the second segment 112 and the third segment 113. That is, the first face 130 and the second face 140 are both annular planar surfaces, and the first face 130, the second face 140, and the second section 112 define the mounting slot 160.

In the air filter assembly 20 according to the embodiment of the present invention, the radial dimension of the second section 112 of the inner circumferential surface 110 of the sealing member 100 is large, the first surface 130, the second surface 140 and the second section 112 define the mounting groove 160, and the mounting groove 160 can be engaged with the rib 213 of the main body 210, so that the sealing property can be improved.

In addition, mounting groove 160 and installed part cooperation back, first face 130 and second face 140 can laminate with two sides of protruding muscle 213 to play limiting displacement, and then can avoid sealing member 100 to drop.

Therefore, the air filter assembly 20 of the embodiment of the utility model has the advantages of good sealing performance and difficult falling-off.

As shown in fig. 2 and 3, the cross-sectional inner peripheral profile of the seal 100 is rectangular. It will be appreciated that the cross-section of the seal 100 is perpendicular to the thickness direction of the seal 100. That is, the first section 111, the second section 112, and the third section 113 of the inner circumferential surface 110 of the sealing member 100 are all surrounded by four planes, and the projections of the first section 111, the second section 112, and the third section 113 of the inner circumferential surface 110 of the sealing member 100 in the thickness direction of the sealing member 100 are all rectangular, wherein the projections of the first section 111 and the third section 113 are located in the projection of the second section 112.

Thus, the air filter assembly 20 of the present embodiment can be mounted on the main body 210 having a rectangular structure.

In some embodiments, as shown in fig. 1 and 2, the radial dimension of the first segment 111 is greater than the radial dimension of the third segment 113. That is, the distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the first segment 111 is greater than the distance between two points where a line perpendicular to the center line of the inner circumferential surface 110 intersects the third segment 113. In other words, the projection of the first section 111 in the thickness direction of the seal 100 is located within the projection of the second section 112 in the thickness direction of the seal 100, and the projection of the third section 113 in the thickness direction of the seal 100 is located within the projection of the first section 111 in the thickness direction of the seal 100.

As shown in fig. 1 and 2, the inner circumferential surface 110 of the seal 100 further includes a fourth segment 114. The first section 111 is located between the fourth section 114 and the second section 112 in the thickness direction of the seal 100, and the radial dimension of the fourth section 114 gradually increases in a direction away from the first section 111. That is, the fourth segment 114 is a tapered peripheral surface surrounded by four inclined surfaces, and can perform a guiding function.

Therefore, when the air filter assembly 20 of the embodiment of the present invention is installed, the installation is started from the end adjacent to the first section 111, so that the sealing member 100 is conveniently sleeved on the main body 210, and the installation of the sealing member 100 is facilitated.

In some embodiments, as shown in fig. 1-3, the seal 100 includes an outer peripheral surface 120, and the outer peripheral surface 120 includes a first side surface 103, a second side surface 104, a third side surface, and a fourth side surface. I.e., the outer circumferential profile of the cross-section of the seal 100 is also rectangular.

The first side surface 103 is located on one side in the width direction of the seal 100 (the left-right direction in fig. 1), the second side surface 104 is located on the other side in the width direction of the seal 100, and the third side surface and the fourth side surface are opposed in the length direction of the seal 100 (the front-back direction in fig. 1).

The extending direction of the projection line of the first side surface 103 on the third side surface is consistent with the thickness direction of the sealing member 100, and the included angle between the projection line of the second side surface 104 on the third side surface and the projection line of the first side surface 103 on the third side surface is greater than 0 degree and smaller than 90 degrees.

That is, the first side surface 103 is a plane, and the second side surface 104 is a slope. Preferably, an included angle between a projection line of the second side surface 104 on the third side surface and a projection line of the first side surface 103 on the third side surface is greater than or equal to 5 degrees and less than or equal to 15 degrees.

It is understood that, in order to improve the filtering effect of the air conditioner in the related art, the air filter assembly is generally disposed to be inclined, so that the filtering area is increased, and it is advantageous for the filtered impurities to fall off, so that the air filter assembly needs to be inserted into the filter chamber to be inclined.

When the air filter assembly 20 of the embodiment of the present invention moves in the oblique direction, the second side surface 104 of the sealing member 100 is an inclined surface and is not easily touched, so that the sealing member 100 can be prevented from falling off.

Therefore, the air filter assembly 20 according to the embodiment of the utility model has the advantages of good sealing performance and difficult falling off.

In some embodiments, as shown in fig. 1-3, the seal 100 of the air filtration assembly 20 of embodiments of the present disclosure includes a first major surface 101 and a second major surface 102. The first main surface 101 and the second main surface 102 are opposed in the thickness direction of the seal 100, the second main surface 102 is a sealing surface, and the width of the outer peripheral profile of the cross section of the seal 100 is gradually reduced in the direction of the first main surface 101 adjacent to the second main surface 102.

That is, the first main surface 101 is an upper surface of the seal 100, the second main surface 102 is a lower surface of the seal 100, and the width of the outer circumferential profile of the cross section of the seal 100 is gradually reduced from top to bottom, and the area of the second main surface 102 is smaller than that of the first main surface 101.

It will be appreciated that the seal 100 is compressed by the fastener to apply pressure to conform the sealing surface to the article 100 to be sealed. The same sealing effect is small, the larger the area of the sealing surface is, the larger the required pressure is; conversely, the smaller the area of the sealing surface, the less pressure is required.

Therefore, the second main surface 102 serves as a sealing surface, and a small pressure is required to achieve a sealing effect.

As shown in fig. 1 and 3, the air filter assembly 20 of the present embodiment further includes a sealing rib 150, the sealing rib 150 being disposed on the second major surface 102, the sealing rib 150 being formed to protrude from the second major surface 102. It will be appreciated that the sealing bead 150 is a sealing strip that encloses a closed shape. Specifically, as shown in fig. 3, the sealing rib 150 has a cross-section with both a rectangular outer and inner peripheral profile.

When the air filter assembly 20 of the present embodiment is installed, the surface of the sealing rib 150 is attached to the sealed member 100, i.e., the surface of the sealing rib 150 forms a sealing surface. Therefore, the area of the seal surface is further reduced, and the pressure required to achieve sealing is also further reduced.

As shown in fig. 1 and 3, the sealing rib 150 is plural, and the plural sealing ribs 150 are arranged at intervals in the inner and outer directions. In particular, there are three sealing ribs 150, a first sealing rib 150 being located within a second sealing rib 150, and the second sealing rib 150 being located within a third sealing rib 150.

Therefore, the plurality of sealing ribs 150 can be sealed individually, thereby achieving a multi-seal effect and improving the sealing performance.

In some embodiments, as shown in FIG. 1, the body 210 includes a first portion 211 and a second portion 212, the second portion 212 having a radial dimension that is less than a radial dimension of the first portion 211, the ribs 213 being disposed on the second portion 212, and the seal 100 being disposed on the second portion 212 of the carrier. That is, the rib 213 is an annular protrusion provided on the outer circumference of the second portion 212, and the mounting groove 160 of the inner circumferential surface 110 of the sealing member 100 is fitted with the rib 213.

It can be understood that the radial dimension of the sealing element 100 is smaller than the radial dimension of the first portion 211, and when the air filter assembly 20 according to the embodiment of the present invention is assembled and disassembled, the first portion 211 of the main body 210 can play a role in protection, so that the outer circumferential surface 120 of the sealing element 100 is not easily touched, and the sealing element 100 can be prevented from falling off.

Therefore, the air filter assembly 20 according to the embodiment of the present invention has the advantages of good sealing performance and difficulty in dropping the sealing member 100.
