Technical Field

[0001] This application relates to the technical field of automotive parts, and more particularly to a water filter for an automobile. Background Art

[0002] The cooling water tank of an automobile is an important device for cooling the heat generated during the driving of the automobile. To reduce impurities from entering the cooling water tank, a water filter is generally installed at the water inlet of the cooling water tank to filter impurities in the water through the water filter.

[0003] In related technologies, a single layer of filter screen is provided inside the water filter to filter impurities in the water. However, the filtering effect of the single layer of filter screen is average, resulting in more impurities remaining in the water. Utility Model Content

[0004] In order to improve the filtering effect and reduce the impurities remaining in the water, this application provides a water filter for an automobile.

[0005] A water filter for an automobile provided by this application adopts the following technical solutions:

[0006] A water filter for an automobile includes a top cover, a housing having a water filtering chamber, and a filter element. The top cover is connected to the housing;

[0007] The filter element includes a first filtering member connected to the top cover and a second filtering member connected to the housing. There is a secondary filtering chamber between the first filtering member and the second filtering member;

[0008] Both the first filtering member and the second filtering member include a support frame and a filter screen mounted on the support frame. The support frame is provided with a magnet for adsorbing magnetic metals.

[0009] By adopting the above technical solutions, during use, the water flowing in from the water inlet pipe first flows into the first filtering member, and the first filtering member filters the water for the first time. Then, the second filtering member filters the water for the second time. Through the secondary filtering, the impurities in the water are reduced. Moreover, when the water flows through the first filtering member and the second filtering member, the magnet can adsorb the magnetic metals in the water, making it difficult for the magnetic metals to block the filter screen and reducing the impurities in the water at the same time.

[0010] Optionally, the support frame includes a plurality of vertically arranged rods and a plurality of radial spokes. The radial spokes extend radially from the center to the periphery, and the end of the radial spoke away from the center is connected to the vertical rod; the magnet of the first filtering member is installed at the center position of the support frame.

[0011] By adopting the above technical solutions, when the water flows into the first filtering member, the magnet can adsorb the magnetic metals in the water.

[0012] Optionally, the magnet of the second filter element is installed on the radial spokes of the support frame.

[0013] By adopting the above technical solution, when water flows into the second filter element, the magnet can adsorb magnetic metals in the water; and since the magnets of the first filter element and the second filter element are staggered in position, the water flowing into the first filter element may not pass through the central position of the support frame but fall from the periphery. At this time, there may be residual magnetic metals in the water; then when the water falls from the periphery of the first filter element and enters the second filter element, the magnet on the radial spoke of the second filter element can adsorb the magnetic metals in the water, further removing impurities in the water.

[0014] Optionally, the top cover is provided with an embedded ring groove for installing the support frame, and the support frame is embedded in the embedded ring groove.

[0015] By adopting the above technical solution, by embedding the support frame in the embedded ring groove, the support frame is connected and fixed to the top cover.

[0016] Optionally, the top of the housing is provided with a fixed ring groove, the second filter element has a flanging that turns outward, and the flanging is snapped into the fixed ring groove.

[0017] By adopting the above technical solution, when the second filter element is connected to the housing, the flanging of the second filter element is embedded in the fixed ring groove, so that the second filter element is connected to the housing.

[0018] Optionally, a compression spring is arranged in the secondary filter cavity, one end of the compression spring abuts against the bottom of the first filter element, and the other end abuts against the second filter element.

[0019] Optionally, a plurality of compression springs are provided, and the plurality of compression springs are arranged at intervals in a ring in the secondary filter cavity.

[0020] By adopting the above technical solution, the upper end of the compression spring abuts against the first filter element, and the lower end abuts against the second filter element. The first filter element and the second filter element are more stable in the water filtering cavity through the compression spring; at the same time, during the long-term use of the vehicle, due to reasons such as water pressure and bumpy vibration, the first filter element and the second filter element may become loose. Through the action of the compression spring, the first filter element and the second filter element are not easily loosened.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. During use, the water flowing in from the water inlet pipe first flows into the first filter element, and the first filter element filters the water for the first time. Then, the second filter element filters the water for the second time, reducing the impurities in the water through the two - stage filtration. Moreover, when the water flows through the first filter element and the second filter element, the magnet can adsorb the magnetic metals in the water, making it difficult for the magnetic metals to block the filter screen and reducing the impurities in the water at the same time.

[0023] 2. Since the magnets of the first filter element and the magnets of the second filter element are staggered in position, the water flowing into the first filter element may fall from the periphery without passing through the central position of the support frame. At this time, there may be residual magnetic metals in the water. When the water falls from the periphery of the first filter element and enters the second filter element, the magnets on the radial spokes of the second filter element can adsorb the magnetic metals in the water, further removing the impurities in the water.

[0024] 3. The upper end of the compression spring abuts against the first filter element, and the lower end abuts against the second filter element, making the first filter element and the second filter element more stable in the water filtering cavity through the compression spring. At the same time, during the long - term use of the vehicle, due to reasons such as water pressure and bumpy vibration, the first filter element and the second filter element may become loose. Through the action of the compression spring, the first filter element and the second filter element are not easily loosened. Brief Description of the Drawings

[0031] The following further elaborates on the present application with reference to the drawings.

[0032] An embodiment of the present application discloses a water filter for an automobile.

[0033] Referring to Figure 1 And Figure 2 , the water filter of the automobile includes a top cover 1, a housing 2 and a filter element 3. The top cover 1 is connected to the housing 2, and the filter element 3 is installed on the top cover 1 and the housing 2, and the water is filtered through the filter element 3.

[0034] Specifically, the top cover 1 is integrally connected with a water inlet pipe 11, the housing 2 is integrally connected with a water outlet pipe 21, and the housing 2 has a water filtering cavity 22 communicated with the water outlet pipe 21. When in use, the top cover 1 covers the water filtering cavity 22 of the housing 2, water flows into the water filtering cavity 22 from the water inlet pipe 11, and after being filtered by the water filtering cavity 22, it flows out from the water outlet pipe 21.

[0035] The filter element 3 includes a first filter element 31 and a second filter element 32. The first filter element 31 is connected to the top cover 1, the second filter element 32 is connected to the housing 2, and a secondary filter cavity 33 is formed between the first filter element 31 and the second filter element 32. When in use, the water flowing in from the water inlet pipe 11 first flows into the first filter element 31, and the water is first filtered by the first filter element 31, and then the second filter element 32 filters the water for the second time, reducing the impurities in the water through secondary filtration.

[0036] See Figure 3 And Figure 4 , both the first filter element 31 and the second filter element 32 include a support frame 34 and a filter screen 35. The support frame 34 is a plastic part, the filter screen 35 is made of stainless steel, the filter screen 35 is integrally installed on the support frame 34 by injection molding, and the mesh number of the filter screen 35 of the second filter element 32 is greater than that of the filter screen 35 of the first filter element 31, that is, the filter screen 35 of the second filter element 32 can filter smaller impurities. When in use, the first filter element 31 first filters the water quality to filter out larger impurities, and then the second filter element 32 filters the water quality for the second time to filter out smaller impurities.

[0037] The support frame 34 includes a plurality of vertical rods 36 arranged in parallel with each other and a plurality of radial spokes 37. The plurality of vertical rods 36 correspond to the plurality of radial spokes 37, and the plurality of radial spokes 37 all extend radially from the center to the periphery, and one end of the radial spoke 37 far from the center is connected to one of the vertical rods 36.

[0038] A ring-shaped magnet 4 is embedded at the center position of the support frame 34 of the first filter element 31, and the magnet 4 is integrally installed in the support frame 34 by injection molding; when water flows into the first filter element 31, the magnet 4 can adsorb magnetic metals in the water.

[0039] The second filter element 32 is fitted with strip-shaped magnets 4 on the radial spokes 37 of the support frame 34. Similarly, the magnets 4 are also integrally installed in the support frame 34 by injection molding. When water flows into the second filter element 32, the magnets 4 can adsorb magnetic metals in the water.

[0040] Moreover, since the positions of the magnets 4 of the first filter element 31 and the magnets 4 of the second filter element 32 are staggered, the water flowing into the first filter element 31 may fall from the periphery without passing through the central position of the support frame 34. At this time, there may be residual magnetic metals in the water. When the water falls from the periphery of the first filter element 31 and enters the second filter element 32, the magnets 4 on the radial spokes 37 of the second filter element 32 can adsorb the magnetic metals in the water, further removing impurities in the water.

[0041] See Figure 2 , the top cover 1 is provided with an embedded ring groove 12 for installing the support frame 34 of the first filter element 31, and the water inlet pipe 11 is located at the center of the embedded ring groove 12. When the first filter element 31 is connected to the top cover 1, the top of the support frame 34 is embedded in the embedded ring groove 12, so that all the water in the water inlet pipe 11 flows into the first filter element 31.

[0042] See Figure 2 And Figure 4 , the top of the housing 2 is provided with a fixed ring groove 23, and the second filter element 32 has a turned-out flange 321. When the second filter element 32 is connected to the housing 2, the flange 321 of the second filter element 32 is snapped into the fixed ring groove 23 of the housing 2, so that the second filter element 32 is connected to the housing 2.

[0043] When the top cover 1 is connected to the housing 2, first place the first filter element 31 into the second filter element 32, then cover the top cover 1 on the housing 2, and connect the top cover 1 and the housing 2 together by vibration friction welding. At the same time, the second filter element 32 can also be connected and fixed to the housing 2.

[0044] See Figure 2 And Figure 5 , a plurality of compression springs 5 are arranged in the secondary filter cavity 33. The plurality of compression springs 5 are arranged vertically and at annular intervals, and the compression springs 5 are in a compressed state. The upper ends of the compression springs 5 abut against the first filter element 31, and the lower ends abut against the second filter element 32. The first filter element 31 and the second filter element 32 are made more stable in the water filtering cavity 22 through the compression springs 5. At the same time, during the long-term use of the vehicle, due to reasons such as water pressure and bumpy vibration, the first filter element 31 and the second filter element 32 may become loose. Through the action of the compression springs 5, the first filter element 31 and the second filter element 32 are not easily loosened.

[0045] The implementation principle of a water filter for an automobile in an embodiment of the present application is as follows: When the water filter is in use, water enters the top cover 1 from the water inlet pipe 11, and after passing through the filtration of the first filter element 31 and the second filter element 32 in sequence, it finally flows out from the outlet pipe, and the impurities remain in the first filter element 31 and the second filter element 32.

[0046] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
