[0027] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The embodiment of the present application provides a filter installation assembly to solve the technical problem in the prior art that the filter installation assembly is not highly adaptable to the filter.

[0030] In the embodiments of the present application, Figure 1-Figure 3 As shown, the filter screen installation assembly includes a guide rail 10, a first fixed plate 20 and an elastic member 30. The guide rail 10 includes a first side plate 11 and a second side plate 12 that are relatively arranged. A guide groove 14 for accommodating the filter screen 50 is formed between the first side plate 11 and the second side plate 12, and the first side plate 11 and the second side plate 12 are configured to limit the filter screen 50 in the thickness direction thereof; one end of the elastic member 30 abuts against the guide rail 10, and the other end of the elastic member 30 abuts against the first fixed plate 20, so that the first fixed plate 20 is movably arranged between the first side plate 11 and the second side plate 12, and under the extrusion action of the elastic member 30, the side of the first fixed plate 20 facing the filter screen 50 abuts against the side surface of the filter screen 50.

[0031] It should be noted that in order to ensure air quality, the filter 50 needs to be replaced regularly, and in the prior art, the size of the filter is adapted to the guide groove, so that only filters of corresponding sizes can be installed in the guide groove. When the user needs to increase the size of the filter to improve the filtering effect, the filter cannot be assembled into the guide groove; or when the user needs to reduce the cost of the filter and reduce the size of the filter, the filter is difficult to fix in the guide groove. Therefore, the existing filtering device is not universal for filters of different sizes and cannot meet the installation requirements of filters of different sizes.

[0032] To this end, the filter installation assembly provided in the present application is provided with a first fixed plate 20 and an elastic member 30 in the guide groove 14. Since the two ends of the elastic member 30 are respectively connected to the guide rail 10 and the first fixed plate 20, the first fixed plate 20 can move relative to the first side plate 11 and the second side plate 12. When the filter 50 is assembled into the guide groove 14, the first fixed plate 20 is abutted against the side of the filter 50 toward the side of the filter 50. Under the squeezing action of the filter 50, the elastic member 30 is elastically deformed, so that filters 50 of various sizes can be installed in the guide groove 14, thereby improving the universal performance of the filter installation assembly and meeting the user's needs for filters 50 of different sizes.

[0033] It is understandable that the filter 50 may include a frame and a filter installed in the frame, the frame may be a rectangular grid structure, the filter may be a mesh structure, and the mesh of the filter may be determined according to actual filtering requirements to filter out dust in the air. In this embodiment, the filter may be assembled by sliding the frame in the guide groove 14. After assembly, one side of the frame is fixed in the guide groove 14, and the filter is located outside the guide groove 14 to filter the air.

[0034] For details, please refer to Figure 2 and Figure 3 The guide rail 10 is a long strip structure, and the cross-section of the guide groove 14 can be rectangular, arc-shaped, etc. When the filter screen 50 is assembled with the filter screen 50 mounting structure, the filter screen 50 is inserted into the guide groove 14 from the length direction of the guide rail 10. At this time, the side of the filter screen 50 is abutted against the first fixed plate 20, and the first fixed plate 20 squeezes the elastic member 30. By pushing the filter screen 50 until one side of the filter screen 50 completely slides into the guide groove 14, the assembly of the filter screen 50 and the guide rail 10 can be achieved.

[0035] The first side plate 11 and the second side plate 12 can be arranged in parallel, and the first side plate 11 and the second side plate 12 are used to limit the filter 50 in the thickness direction to prevent the filter 50 from falling out. In an optional embodiment, the first side plate 11 and the second side plate 12 are respectively abutted against the filter 50 on both sides in the thickness direction, and the first fixing plate 20 is used to limit the filter 50 in the length or width direction. Under the elastic force of the elastic member 30, it can be ensured that the guide rail 10 can adapt to the filter 50 of different lengths or widths, meet the different usage requirements of users, and improve the universal performance of the filter installation assembly.

[0036] In some embodiments, there are two filter installation components, which are respectively installed on opposite sides of the filter 50, that is, both ends of the filter 50 in the length or width direction are slidably set in the guide groove 14, and both ends of the filter 50 in the length or width direction are abutted against the first fixed plate 20. In this way, not only the installation of the filter 50 is ensured to be more stable, but also the general performance of the filter installation component is further improved, thereby improving the user experience.

[0037] Optionally, in one embodiment, see Figure 4-Figure 7 The filter installation assembly also includes a second fixing plate 40 arranged on the second side plate 12, and the second fixing plate 40 is spaced apart from the first side plate 11; the first side plate 11, the second side plate 12 and the side of the second fixing plate 40 facing away from the first side plate 11 are enclosed to form a first installation position, and the first side plate 11, the first fixing plate 20 and the side of the second fixing plate 40 facing away from the second side plate 12 are enclosed to form a second installation position, and the first installation position and the second installation position are used to install filters 50 of different models.

[0038] In this embodiment, the guide rail 10 is installed in the length direction of the filter 50. The first installation position is suitable for the installation of the filter 50 with a larger thickness value and a smaller width value, and the second installation position is suitable for the installation of the filter 50 with a smaller thickness value and a larger width value.

[0039] Specifically, the second fixing plate 40 is fixedly connected to the second side plate 12, and an opening 15 for the filter 50 to pass through is formed between the second fixing plate 40 and the first side plate 11. The second fixing plate 40 is arranged parallel to the first fixing plate 20 and spaced apart. The second fixing plate 40 is located on the side of the first fixing plate 20 that is away from the elastic member 30. In this embodiment, a filter installation assembly can be provided on both sides of the filter 50 in the length direction, so that the filter 50 is fixed by the second fixing plates 40 on both sides of the filter 50. The distance between the two second fixing plates 40 can be determined according to the filter 50 with a higher usage rate in the market, so that the filter installation assembly can be used in a targeted market and improve the universal performance of the filter installation assembly.

[0040] See also Figure 5 and Figure 6 When the user needs to increase the thickness of the filter 50 to improve the filtering effect, and does not change the width of the filter 50, the filter 50 can still be fixed to the second fixing plate 40 due to the large spacing between the first side plate 11 and the second side plate 12, that is, the two sides of the filter 50 in the length direction are respectively abutted against the second fixing plate 40, thereby achieving the installation of the filter 50; please refer to Figure 7 When the user subsequently needs to reduce the cost of the filter 50 and reduce the thickness of the filter 50, and increase the width of the filter 50, the two ends of the filter 50 in the length direction thereof pass through the opening 15 and abut against the first fixing plate 20. At this time, the side of the second fixing plate 40 facing away from the second side plate 12 and the first side plate 11 are used to limit the filter 50 in the thickness direction, and the two sides of the filter 50 in the length direction abut against the first fixing plate 20, thereby achieving the installation of the filter 50. In this embodiment, the filter installation assembly can adapt to the installation of filters 50 of different thicknesses and widths, greatly improving the universal performance of the filter installation assembly and meeting the different usage requirements of users.

[0041] Optionally, in one embodiment, see Figure 2 and Figure 3, the first fixed plate 20 is provided with a first guide portion 21 for guiding the filter 50 into the guide groove 14; and / or, the second fixed plate 40 is provided with a second guide portion 41 for guiding the filter 50 into the guide groove 14. Through the provision of the first guide portion 21 and the second guide portion 41, it is very easy to insert the filter 50 into the guide groove 14, so that the assembly of the filter 50 and the filter installation assembly is relatively easy, and the installation efficiency of the filter 50 is improved. When the filter 50 can be assembled from both ends of the first fixed plate 20, the first guide portion 21 can also be provided at both ends of the first fixed plate 20 in this embodiment, so as to improve the universal performance of the filter installation assembly and adapt to different installation conditions. Similarly, when the filter 50 can be assembled from both ends of the second fixed plate 40, the second guide portion 41 can also be provided at both ends of the second fixed plate 40 in this embodiment, so as to improve the universal performance of the filter installation assembly and adapt to different installation conditions.

[0042] For further information, see Figure 2-Figure 4 , the first guide portion 21 and the second guide portion 41 are both guide slopes. One end of the first guide portion 21 is connected to the first fixed plate 20, and the other end of the first guide portion 21 extends toward the bottom of the guide groove 14. The angle formed between the first fixed plate 20 and the first guide portion 21 is an obtuse angle. The first fixed plate 20 and the first guide portion 21 can be connected in a straight line or in an arc. In a preferred embodiment, the angle formed between the first fixed plate 20 and the first guide portion 21 is between 130°-150°. Since the filter screen 50 needs to be installed against the first fixed plate 20, that is, the distance between the filter screen 50 and the first fixed plate 20 is 0, the setting of the first guide portion 21 facilitates the insertion of the filter screen 50 into the guide groove 14, simplifies the installation of the filter screen 50, and improves the installation efficiency of the filter screen 50.

[0043] Similarly, one end of the second guide portion 41 is connected to the second fixing plate 40, and the other end of the second guide portion 41 extends toward the bottom of the guide groove 14. The angle formed between the second fixing plate 40 and the second guide portion 41 is an obtuse angle. The second fixing plate 40 and the second guide portion 41 can be connected in a straight line or in an arc. In this way, the installation of the filter 50 is simplified and the installation efficiency of the filter 50 is improved.

[0044] Optionally, in one embodiment, see Figure 1-Figure 3 The guide rail 10 also includes a bottom plate 13 , a first side plate 11 and a second side plate 12 are respectively connected to two opposite sides of the bottom plate 13 , and the first side plate 11 , the second side plate 12 and the bottom plate 13 enclose a guide groove 14 .

[0045] Specifically, the bottom plate 13 has a first side and a second side opposite to each other, the first side plate 11 is connected to the first side of the bottom plate 13, the second side plate 12 is connected to the second side of the bottom plate 13, and the first side plate 11 and the second side plate 12 can be arranged in parallel to form a guide groove 14 with a rectangular cross section, so that the filter screen can slide in the guide groove 14. In this embodiment, the first side plate 11, the second side plate 12 and the bottom plate 13 can be arranged in one piece, thereby improving the overall structural strength of the guide rail 10, while facilitating the production and processing of the guide rail 10 and improving assembly efficiency.

[0046] Optionally, in one embodiment, see Figure 3 and Figure 8 , a flange 131 is provided on one side of the bottom plate 13 close to the first side plate 11, and the first side plate 11 is detachably connected to the flange 131.

In order to make the connection between the first side plate 11 and the flange 131 more stable, the first side plate 11 and the flange 131 can be connected and fixed by multiple screws.

[0047] See also Figure 8 By detachably connecting the first side panel 11 and the flange 131, when replacing the filter 50, the filter 50 can be removed not only from the installation direction of the first side panel 11, but also from the length direction of the guide rail 10, making the disassembly and assembly of the filter 50 more convenient, and being able to meet the disassembly and assembly requirements of the filter 50 in different scenarios, thereby improving the practical performance of the filter installation assembly.

[0048] Optionally, in one embodiment, see Figure 2-Figure 4 A plurality of protrusions 121 are arranged at intervals at one end of the second side plate 12 away from the bottom plate 13 , and a third guide portion 122 is provided at both ends of each protrusion 121 , and the third guide portion 122 extends toward a side away from the first side plate 11 .

[0049] Specifically, the third guide portion 122 may be a guide slope, the angle formed between the protrusion 121 and the third guide portion 122 is an obtuse angle, the protrusion 121 and the third guide portion 122 may be connected by a straight line transition or an arc transition. In this embodiment, please refer to Figure 2 and Figure 6The protrusion 121 is used to limit the filter screen 50 in the thickness direction, and the second fixing plate 40 is used to limit the filter screen 50 in the width direction. Therefore, the third guide portion 122 is used to guide the filter screen 50 in the thickness direction, and the second guide portion 41 is used to guide the filter screen 50 in the width direction.
