Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and more specifically, to an air inlet mesh plate installation structure. Background Technology

[0002] Air purifiers are products that can adsorb, decompose, or transform various air pollutants to effectively improve air cleanliness. Some air purifiers have a perforated mesh air inlet panel that covers the air inlet and filters large particulate pollutants. To facilitate cleaning and maintenance of the air inlet panel, some existing models use threaded connections or magnetic adsorption to fix the panel. However, while threaded connections are reliable, disassembly is cumbersome. Magnetic adsorption offers quick removal, but the adhesion may not be secure, affecting the normal use of the air inlet panel. Therefore, developing a stable, reliable, and easy-to-remove installation structure for the air inlet panel is a pressing technical problem. Utility Model Content

[0034] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0035] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0036] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0037] Please see Figures 1 to 3 The air inlet mesh panel 2 mounting structure provided in one embodiment of this utility model mainly includes a body 1, an air inlet mesh panel 2, and a movable component 3. The air inlet mesh panel 2 is located in front of the body 1, and has several air inlet holes. It also has a first fastening part 21, which extends from front to back and into the body 1. The movable component 3 has an operating part 3111 exposed on the body 1 and a second fastening part 321 located inside the body 1. The movable component 3 is movable on the body 1 in the left-right direction, allowing the air inlet mesh panel 2 mounting structure to have a locked state and an unlocked state. In the locked state, the second fastening part 321 engages with the first fastening part 21, preventing the first fastening part 21 from retracting forward from the body 1, thus fixing the air inlet mesh panel 2 to the body 1. In the unlocked state, the second fastening part 321 is released from the first fastening part 21.

[0038] In the installation structure of the air inlet mesh plate 2 in this embodiment of the utility model, in the locked state, the air inlet mesh plate 2 is fixedly installed on the body 1 by the mutual fastening between the first fastener 21 and the second fastener 321. Since the second fastener 321 can restrict the first fastener 21 from moving forward out of the body 1, it is difficult for the air inlet mesh plate 2 to detach from the body 1 from the installation direction, thereby ensuring that the air inlet mesh plate 2 can be stably and reliably installed on the body 1 so as to perform its function normally.

[0039] Specifically, when the user applies force to the operating part 3111 exposed on the main body 1, it can drive the moving part 3 to move to the left or right relative to the main body 1, and drive the second buckle 321 on the moving part 3 to move inside the main body 1, so as to switch from the locked state to the unlocked state. Since the second buckle 321 can be unhooked from the first buckle 21 in the unlocked state, and does not restrict the first buckle 21 from leaving the main body 1, at this time, it is only necessary to move the air intake mesh 2 forward as a whole, and drive the first buckle 21 out of the main body 1, so that the air intake mesh 2 can be removed from the main body 1 as a whole. The removal method is relatively quick and simple and easy to implement.

[0040] It is conceivable that the action of applying force to the operating part 3111 can be either pressing or pulling.

[0041] Please see Figure 2 and Figure 3 In a specific embodiment, the operating part 3111 and the second fastening part 321 are arranged at intervals in the left-right direction, and the first fastening part 21 is located between the operating part 3111 and the second fastening part 321 in the left-right direction. The air inlet mesh plate 2 mounting structure also includes an elastic element 4, which is installed in the body 1 and is used to provide elastic force to drive the second fastening part 321 to move towards the side closer to the first fastening part 21 in the left-right direction.

[0042] When the operating part 3111 is not operated by external force, the second latch 321 can approach the first latch 21 under the elastic force of the elastic member 4 and remain in the position where it is engaged with the first latch 21, thereby ensuring the stability of the air inlet mesh plate 2 installation structure in the locked state. When the user presses on the operating part 3111, since both the operating part 3111 and the second latch 321 are located on the moving member 3, the pressing force pushes the second latch 321 to move in the left-right direction along the side away from the first latch 21 and disengage from the first latch 21. During this process, the elastic member 4 deforms and accumulates elastic potential energy, and can drive the second latch 321 to reset when the pressing action ends, preparing for the next installation. In this embodiment, the elastic member 4 is a compression spring.

[0043] In other embodiments, the operating part 3111, the second latch 321, and the first latch 21 are arranged sequentially in the left-right direction. The air inlet mesh plate 2 mounting structure also includes an elastic element 4, which is installed inside the body 1 and is used to provide elastic force to drive the second latch 321 to move in the left-right direction along the side closer to the first latch 21. The elastic element 4 is a tension spring. In this embodiment, the user's action of pulling the operating part 3111 can cause the second latch 321 to disengage from the first latch 21. During this process, the elastic element 4 deforms and accumulates elastic potential energy, and can drive the second latch 321 to reset when the pulling action ends, preparing for the next installation.

[0044] Please see Figure 5 and Figure 6 In a specific embodiment, the main body 1 has a window 1111, within which a slide rail 14 is provided. The movable component 3 includes a button 31 and a slide base 32 arranged sequentially in the left-right direction. The button 31 is movably mounted in the window 1111 in the left-right direction, and the slide base 32 is slidably connected to the slide rail 14 so as to be movable in the left-right direction. The button 31 has an operating part 3111 on the side away from the slide base 32 in the left-right direction, and the slide base 32 has a second latching part 321 on the side away from the button 31 in the left-right direction. The other side of the button 31 in the left-right direction abuts against the other side of the slide base 32 in the left-right direction.

[0045] Through the cooperation between button 31 and window 1111, the cooperation between slide 32 and slide rail 14, and the abutting relationship between button 31 and slide 32, the force applied by the user to the operating part 3111 can be effectively transmitted to the slide 32 to drive the second latch 321 to move. The split design allows button 31 and slide 32 to be designed independently, reducing the design and installation difficulty of the moving part 3, and making it easy to maintain and replace.

[0046] Please see Figure 4 In a specific embodiment, the body 1 includes a shell 11, a main body 12 and a connector 13. The shell 11 is fitted over the main body 12 and has a window 1111. The main body 12 can be inserted into the first buckle 21. The connector 13 is located inside the shell 11 and is connected to the main body 12 to form a slide 14.

[0047] The shell 11 is fitted over the main body 12, which protects the internal main body 12 and the connector 13. The main body 12 serves as the core support, providing a stable foundation for the installation of the air inlet mesh 2. The connector 13 is connected to the main body 12 to form a slide 14. This design makes the forming of the slide 14 more flexible. The modular design of the shell 11, the main body 12 and the connector 13 makes the installation and maintenance process simpler.

[0048] Please see Figure 5 and Figure 6 In a specific embodiment, the housing 11 is provided with a mounting groove 111. The groove wall of the mounting groove 111 in the left-right direction has a window 1111 and two limiting ports 1112, and one limiting port 1112, the window 1111 and the other limiting port 1112 are arranged vertically. The button 31 includes a base 311 and a support part 312 and two limiting parts 313 provided on the base 311. The support part 312 and the limiting parts 313 both extend in the left-right direction, and one limiting part 313, the support part 312 and the other limiting part 313 are arranged vertically. The support part 312 passes through the window 1111 and abuts against the slide 32. The limiting part 313 passes through the limiting port 1112 and forms a limiting engagement with the limiting port 1112 to restrict the button 31 from disengaging from the mounting groove 111 in the left-right direction.

[0049] The cooperation between the support part 312 and the window 1111, and between the limiting part 313 and the limiting port 1112, can provide guidance for the button 31 to move in the left and right directions. The limiting part 313 and the limiting port 1112 can also form a limiting cooperation to restrict the button 31 from coming out of the mounting groove 111 in the left and right directions. This arrangement can improve the smoothness of the movement of the button 31 on the one hand, and ensure that the button 31 is stably installed in the mounting groove 111 on the other hand, thereby improving the stability and reliability of the overall structure.

[0050] Please see Figure 8 In a specific embodiment, the slide 32 has a slot 322 extending through its front and rear sides. A second latching part 321 protrudes from one wall of the slot 322 in the left-right direction and extends in that direction. The first latching part 21 includes a connecting part 211 and a locking part 212. The connecting part 211 extends from front to back, passes through the slot 322, and its front side is connected to the air inlet mesh plate 2, while its rear side is connected to the locking part 212, which extends in the left-right direction. In the locked state, the locking part 212 is located behind the second latching part 321 and abuts against it in the front-back direction. The slot 322 on the slide 32 provides a passage for the latching part 212 of the first latching part 21 to move to the rear of the second latching part 321. Through the cooperation between the slot 322, the second latching part 321, the connecting part 211 and the latching part 212, a specific and feasible structure is provided for the mutual engagement of the first latch and the second latch, and the overall layout is relatively compact and reasonable.

[0051] Please see Figure 2 and Figure 3In a specific embodiment, the front side of the second buckle 321 has a slope, and the thickness of the second buckle 321 in the left-right direction gradually increases from the side away from the groove wall of the slot 322 to the side closer to the groove wall of the slot 322. The rear side of the latching part 212 has a slope, and the thickness of the latching part 212 in the left-right direction gradually increases from the side away from the connecting part 211 to the side closer to the connecting part 211.

[0052] During the installation of the air inlet grille 2, the backward movement of the first latch 21 first causes the slope of the latch 212 to engage with the slope of the second latch 321. Continued backward movement allows the latch 212 to gradually push the second latch 321 to move laterally, smoothly passing through the slot 322 to the rear of the second latch 321. Under the elastic action of the elastic element 4, the second latch 321 moves towards the connecting part 211, allowing it to engage with the latch 212 in the front-to-back direction. The engagement of the two slopes and the elastic element 4 eliminate the need to simultaneously press the operating part 3111 during the installation of the air inlet panel, making the operation quick and convenient.

[0053] In a specific embodiment, a sleeve 143 extending in the left-right direction is provided inside the slide rail 14. The button 31, slide 32, and elastic element 4 are arranged sequentially in the left-right direction. A mounting groove 323 is provided on the side of the slide 32 facing the elastic element 4. The elastic element 4 is a spring that extends in the left-right direction, sleeved over the sleeve 143, and extends into the mounting groove 323. The sleeve 143 and mounting groove 323 provide accurate positioning for the installation of the elastic element 4, ensuring that the elastic element 4 can correctly and stably provide elastic force to the slide 32 and its second latch 321.

[0054] Please see Figure 2 , Figure 3 and Figure 7 In a specific embodiment, the slide rail 14 extends in the left-right direction and is provided with positioning strips 141 and positioning grooves 142 extending in the left-right direction, respectively, and the positioning strips 141 and positioning grooves 142 are arranged opposite to each other in the front-back direction. The slide block 32 is provided with mating grooves 324 and mating strips 325 that respectively cooperate with the positioning strips 141 and positioning grooves 142, and the positioning grooves 142 and mating strips 325 can form a limiting fit to restrict the left-right movement of the slide block 32 so as to disengage from the slide rail 14.

[0055] The engagement between the positioning bar 141 and the mating groove 324, as well as between the positioning groove 142 and the mating bar 325, reduces the wobbling and offset of the slide block 32 during movement, thereby improving the accuracy of the slide block 32 and its sliding within the slide rail 14. Furthermore, the limiting engagement formed between the positioning groove 142 and the mating bar 325 prevents the slide block 32 from accidentally dislodging from the slide rail 14, thus improving the stability and reliability of the overall structure.

[0056] In this embodiment, the positioning strip 141 is provided on the main body 12, and the positioning groove 142 is provided on the connector 13.

[0057] Please see Figure 9 and Figure 10 In a specific embodiment, the air inlet mesh plate 2 is also provided with a plug-in portion 22, which extends from front to back and is located below the first fastening portion 21. At least two plug-in portions 22, two first fastening portions 21, and two moving parts 3 are provided, and each plug-in portion 22, each first fastening portion 21, and each moving part 3 is spaced apart in the left-right direction. The front side of the main body 1 has a number of plug-in interfaces 121 equal to the number of plug-in portions 22 and a number of clearance openings 122 equal to the number of first fastening portions 21. The plug-in interfaces 121 are used to form a plug-in engagement with the plug-in portions 22, and the clearance openings 122 allow the first fastening portions 21 to extend into the main body 1.

[0058] During disassembly, the user unlocks all the first latches 21 and second latches 321 by pressing the operating part 3111, and then simply pulls the air inlet grille 2 forward to separate all the plugs 22 from the plug interfaces 121. Through the interlocking of multiple first latches 21 and multiple second latches 321 of the moving parts 3, and the insertion of multiple plugs 22 and plug interfaces 121, a multi-point fixing connection is formed. This multi-point fixing can distribute stress, thereby greatly enhancing the connection strength and stability between the air inlet grille 2 and the body 1. On the other hand, the first latches 21 and the clearance opening 122, as well as the plugs 22 and the plug interfaces 121, provide multiple positioning points for the air inlet grille 2, enabling quick and precise installation.

[0059] In this embodiment, the plug-in part 22 and the plug interface 121 can form a limiting fit that restricts the plug-in part 22 from coming out of the plug interface 121 in the front-back direction. In specific disassembly and assembly scenarios, the air inlet mesh plate 2 needs to be rotated at a certain angle so that the plug-in part 22 can be smoothly inserted into or pulled out of the plug interface 121.

[0060] In this embodiment, both the insertion interface 121 and the clearance port 122 are provided on the main body 12.

[0061] In the above embodiments, the first buckle 21 is detachably connected to the air inlet grille 2. Since the first buckle 21 is detachably connected to the air inlet grille 2, the slide 32 and the button 31 are separately arranged, and the main body 12 is connected to the connector 13 to form a slide 14. Specifically, different models of the first buckle 21, slide 32 and connector 13 can be replaced according to actual usage requirements.

[0062] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
