Description

Technical Field

[0001] This application relates to the field of air purifiers, and more particularly to a side cover assembly and an air purifier. Background Technology

[0002] As a core device for improving indoor air quality, the rationality of the casing structure design of air purifiers is crucial to the overall performance and reliability of the machine. Currently, the casing of mainstream products typically consists of a top cover, a bottom cover, and a side cover with an air intake function. The side cover generally adopts a grille structure to achieve unobstructed airflow. With the industry's technological iteration and upgrading, high-power, high-airflow products are gradually becoming the market mainstream, which places higher demands on the structural strength of the casing components. As a key component that withstands the vibration and airflow impact of the fan system, the side cover is prone to mechanical stress concentration under long-term high-intensity operation, leading to plastic deformation at the grille connection points. This structural deformation not only compromises the casing's sealing performance, causing secondary pollution risks, but also alters the internal airflow distribution, causing problems such as filter displacement and motor eccentricity. In severe cases, it can lead to systemic failures such as increased abnormal noise and decreased filtration efficiency. Existing technologies mainly improve the side cover strength by increasing the wall thickness of the engineering plastic or locally improving the arrangement of the grille ribs. However, these methods are limited by material properties and structural design space, making it difficult to effectively disperse the stress peaks generated by dynamic loads, while also increasing material costs and complicating the molding process. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a side cover assembly and an air purifier.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A side cover assembly, comprising:

[0008] A first reinforcing plate is disposed in the receiving groove, with its end located within the slot, and the end of the first reinforcing plate away from the receiving groove is used to fix it to the bottom cover.

[0009] Furthermore, the inner wall of the receiving groove is provided with at least one first protrusion along the length direction, and the first reinforcing plate is provided with at least one fixing hole, the first protrusion extending into the fixing hole.

[0010] Furthermore, the first reinforcing plate includes a first plate body, the first plate body includes a substrate, and side plates are integrally formed on both sides of the substrate. The substrate and the side plates define a groove, and the groove faces away from the opening of the substrate and toward the side cover.

[0011] Furthermore, the first plate has a U-shaped cross-section.

[0012] Furthermore, a second plate is integrally formed at the end of the first plate away from the slot, and the second plate is used for detachable connection with the bottom cover.

[0013] Furthermore, the second plate includes a connecting plate integrally formed with the first plate, the connecting plate extending perpendicularly to the first plate in a direction away from the slot opening, and the connecting plate is provided with positioning holes.

[0014] Furthermore, a support plate is provided on the side cover. The support plate includes a connecting portion provided on the side cover. Support portions are provided on both sides of the connecting portion. The support portions extend and protrude from the surface of the connecting portion facing the connecting plate. A through hole coaxial with the positioning hole is opened on the connecting portion. The support portion abuts against the connecting plate.

[0015] This application also provides an air purifier, which includes:

[0016] The side cover assembly described in any of the preceding claims, wherein the number of side cover assemblies is two;

[0017] A front cover, which is disposed on one side of the two side covers and is connected to the side covers;

[0018] A rear cover is disposed on the side of the two side covers away from the front cover, and the rear cover is connected to the side covers;

[0022] This application avoids plastic deformation of the side cover caused by mechanical stress concentration by setting a receiving groove and a slot at the edge of the side cover, and installing the first reinforcing plate in the receiving groove and inserting its end into the slot and fixing it to the bottom cover. This eliminates the need to increase the wall thickness of the side cover or change the arrangement of the grid ribs, thereby reducing material costs and the complexity of the molding process.

[0040] This application provides a side cover assembly for an air purifier. The side cover assembly includes a side cover 100 and a first reinforcing plate 120. Specifically, a receiving groove 110 is provided at the edge of the side cover 100, and a slot 111 is also provided on the side cover 100. The slot 111 is located at the end of the receiving groove 110 and communicates with the receiving groove 110. The first reinforcing plate 120 is disposed in the receiving groove 110, and the end of the first reinforcing plate 120 is located in the slot 111. The end of the first reinforcing plate 120 away from the receiving groove 110 is used to fix it to the bottom cover 400 of the air purifier.

[0041] See Figure 1 and Figure 2 As shown, the receiving groove 110 is formed on one side of the grid of the side cover 100, and the receiving groove 110 is formed along the height direction. Furthermore, in order to fix the first reinforcing plate 120 inside the receiving groove 110, a corresponding slot 111 is formed on the side cover 100 at the top of the receiving groove 110. During installation, the top of the first reinforcing plate 120 can extend into the slot 111, thereby fixing the top of the first reinforcing plate 120. The bottom of the first reinforcing plate 120 is fixed to the bottom cover 400, thus completing the fixation of the top and bottom of the first reinforcing plate 120 to the side cover 100. It can be understood that... Since the first reinforcing plate 120 is fixedly installed on one side of the grid, and the first reinforcing plate 120 is arranged in the receiving groove 110 along the height direction, if the grid is deformed, it will affect the part on one side of the grid. This part is fixedly connected by the first reinforcing plate 120, thereby improving the mechanical strength and its resistance to deformation, and preventing the side cover 100 from deforming. This application can improve the mechanical strength of the side cover 100 without improving the arrangement of the grid ribs, thereby preventing it from deforming and causing component displacement and abnormal noise. Furthermore, since the first reinforcing plate 120 is located on one side of the grid, it will not affect the air intake of the air inlet.

[0042] In this embodiment, the first reinforcing plate 120 is made of metal, such as lightweight materials like aluminum alloy. Compared with plastic materials, metal materials have stronger mechanical properties, further preventing deformation of the side cover 100 that could cause the component to move.

[0043] In some specific embodiments, the inner wall of the receiving groove 110 is provided with at least one first protrusion 112 along the length direction, and the first reinforcing plate 120 is provided with at least one fixing hole 1210, with the first protrusion 112 extending into the fixing hole 1210.

[0044] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, the first protrusion 112 is a screw post. At least one first protrusion 112 is provided along the length direction, i.e. the height direction, on the inner bottom wall of the receiving groove 110. Correspondingly, a fixing hole 1210 is opened on the first reinforcing plate 120. Screws can be inserted through the fixing hole 1210 into the first protrusion 112. The first reinforcing plate 120 is fastened in the receiving groove 110 by screws, so that it can fully contact the surface of the side cover 100 and support the side cover 100 to prevent it from deforming.

[0045] It is understandable that by opening a slot 111 on the side cover 100 at the top of the receiving groove 110, a first protrusion 112 and a fixing hole 1210 can be omitted, reducing the fastening time of the first reinforcing plate 120 and improving production assembly efficiency.

[0046] In some specific embodiments, the first reinforcing plate 120 includes a first plate body 121, the first plate body 121 includes a substrate 1211, and side plates 1212 are integrally formed on both sides of the substrate 1211. The substrate 1211 and the side plates 1212 define a groove 1213, and the groove 1213 faces away from the opening of the substrate 1211 and towards the side cover 100.

[0047] Please see Figure 4 As shown, in this embodiment, in order to prevent the substrate 1211 from deforming, side plates 1212 protruding from its surface are provided on both sides of the substrate 1211. The side plates 1212 are used to improve the ability of the substrate 1211 to bend under force. In this embodiment, the substrate 1211 and the two side plates 1212 are integrally formed to enhance the connection strength between the substrate 1211 and the side plates 1212.

[0048] In this embodiment, the first plate 121 has a U-shaped cross-section.

[0049] In some specific embodiments, a second plate 122 is integrally formed at the end of the first plate 121 away from the slot 111, and the second plate 122 is used to be detachably connected to the bottom cover 400 of the air purifier.

[0050] Specifically, the second plate 122 includes a connecting plate 1221 integrally formed with the first plate 121. The connecting plate 1221 extends perpendicularly to the first plate 121 in a direction away from the opening of the slot 1213, and a positioning hole 1222 is provided on the connecting plate 1221.

[0051] Please see Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, in order to fix the bottom of the first plate 121, a second plate 122 is provided at the bottom of the first plate 121. Specifically, a connecting plate 1221 integrally formed with the substrate 1211 is provided at the bottom of the substrate 1211. In order to enable the connecting plate 1221 to cooperate with the second protrusion 411 of the bottom cover 400, a positioning hole 1222 coaxially adapted to the second protrusion 411 is provided on the connecting plate 1221. During installation, the positioning hole 1222 only needs to pass through the second protrusion 411 to position the connecting plate 1221, that is, to position the bottom of the substrate 1211 and keep its position unchanged. Since the connecting plate 1221 is fixedly connected to the side cover 100 through the cooperation of the fixing hole 1210 and the first protrusion 112, the cooperation of the positioning hole 1222 and the second protrusion 411 is added to further improve the connection strength between the side cover 100 and the bottom cover 400, thereby preventing the side cover 100 and the bottom cover 400 from moving and causing abnormal noise.

[0052] In some specific embodiments, a support plate 130 is provided on the side cover 100. The support plate 130 includes a connecting portion 131 provided on the side cover 100. Support portions 132 are provided on both sides of the connecting portion 131. The support portions 132 extend out of the surface of the connecting portion 131 facing the connecting plate 1221. A through hole 133 coaxial with the positioning hole 1222 is provided on the connecting portion 131. The support portion 132 abuts against the connecting plate 1221.

[0053] See Figure 1 , Figure 2 as well as Figure 5 As shown, in this embodiment, in order to further improve the connection strength between the side cover 100 and the bottom cover 400 and the connection strength between the side cover 100 and the first reinforcing plate 120, a support plate 130 is provided at the bottom of the second plate body 122 of the first reinforcing plate 120. The support plate 130 supports the second plate body 122. When the side cover 100 and the bottom cover 400 are connected, the support plate 130 can be inserted into the position of the second protrusion 411 of the bottom cover 400. The bottom cover 400, the support plate 130 and the second plate body 122 are fixed together by screws to achieve fixation.

[0054] Specifically, the connecting part 131 is integrally formed with the side cover 100, and the connecting part 131 has integrally formed support parts 132 on both sides. The upper surface of the support part 132 contacts the bottom surface of the second plate 122 to support the first plate 121. A through hole 133 is also provided on the connecting part 131, and the through hole 133 is coaxial with the positioning hole 1222. When the side cover 100 is connected to the bottom cover 400, the second protrusion 411 of the bottom cover 400 can pass through the through hole 133 and the positioning hole 1222, making the connection between the side cover 100 and the first reinforcing plate 120 more secure.

[0055] This application embodiment also provides an air purifier. Specifically, the purifier includes any of the side cover assemblies, a front cover 200, a rear cover 300, and a bottom cover 400 as described above. Specifically, there are two side cover assemblies, each including a side cover 100. The front cover 200 is connected to the side cover 100, and the rear cover 300 is disposed on the side of the two side covers 100 away from the front cover 200. The rear cover 300 is connected to the two side covers 100, and the bottom cover 400 is connected to the side cover 100, the front cover 200, and the rear cover 300 respectively. The two side covers 100 are arranged opposite to each other on the bottom cover 400.

[0056] Please see Figure 6 and Figure 7 As shown, in this embodiment, the outer shell of the air purifier is mainly composed of two side covers 100, a front cover 200, a rear cover 300, a bottom cover 400, and a top cover (not shown). The two side covers 100, the front cover 200, and the rear cover 300 are all connected to the bottom cover 400. The side cover assembly is used to improve the structural strength of the side cover 100 and the connection strength between it and the bottom cover 400, thereby preventing the side cover 100 from deforming and generating abnormal noise.

[0057] In some specific embodiments, a second reinforcing plate 500 is provided at the connection between the front cover 200 and the side cover 100. The second reinforcing plate 500 is snapped onto the front cover 200, and the front cover 200 abuts against the side cover 100.

[0058] Please see Figure 6 and Figure 7 As shown, the second reinforcing plate 500 is snapped and fixed to the front cover 200, and a vertical channel is formed between the second reinforcing plate 500 and the front cover 200. This channel is used to house the wiring and avoid messy wiring.

[0059] In some specific embodiments, the bottom cover 400 includes a first cover body 410 and a second cover body 420. The first cover body 410 and the second cover body 420 are detachably connected. A second protrusion 411 is provided on the side of the first cover body 410 facing the second cover body 420. The second protrusion 411 is detachably connected to the first reinforcing plate 120.

[0060] Please see Figure 8As shown, the bottom cover 400 mainly includes a first cover body 410 and a second cover body 420. The first cover body 410 is provided with a second protrusion 411 at the position of the first reinforcing plate 120. In this embodiment, the second protrusion 411 is a screw post. Specifically, when the side cover 100 and the bottom cover 400 are installed and connected, the support plate 130 first abuts against the second plate 122, and then the through hole 133 of the support plate 130 and the positioning hole 1222 of the second plate 122 pass through the second protrusion 411, thereby fixing the position of the side cover 100 and the first reinforcing plate 120 and improving the connection strength between the side cover 100 and the bottom cover 400.
