[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] The purpose of this utility model is to provide a detachable air purifier to solve the problems existing in the background technology. Without damaging the connection structure of the side wall, the filter and fan components can be easily disassembled and maintained, thereby ensuring the integrity and aesthetics of the overall structure of the air purifier.
[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0041] like Figures 1-2 As shown, this embodiment provides a detachable air purifier, including a top cover 1, a bottom cover 2, and a side wall 3 that surround and form the air purifier housing. An air outlet 11 is provided on the top cover 1, and an air inlet 31 is provided on the side wall 3. The top cover 1 and the bottom cover 2 are detachably connected to the side wall 3. A filter 4 is provided inside the air purifier housing, and the filter 4 is located on the bottom cover 2. The peripheral side of the filter 4 is opposite to the air inlet 31. An air guide grille 5 is provided above the filter 4, and the air guide grille 5 is detachably connected to the side wall 3. An air duct 6 is provided above the air guide grille 5, and a fan assembly 7 is detachably fixed inside the air duct 6. The air duct 6 is located below the top cover 1.
[0042] Specifically, in this embodiment, the air purifier has a square structure, and its sidewall 3 includes four sides, three of which are provided with air inlets 31. Figure 2 As shown, the filter 4 is roughly cylindrical, with its peripheral side as the air inlet and its top surface as the air outlet. Under the action of the fan assembly 7, air flows in from the air inlet 31 of the side wall 3, passes through the peripheral side of the filter 4 and enters the cavity in the middle of the filter 4, then flows upward and flows out from the top of the cavity into the air guide grille 5. After being guided and noise-reduced by the air guide grille 5, it flows out from the air outlet 11 of the top cover 1.
[0043] When filter 4 needs to be replaced, simply invert the air purifier, remove the bottom cover 2, and take out filter 4 for cleaning or replacement. The operation is simple and does not require disassembly of the side wall 3, ensuring the integrity of the overall structure of the air purifier. After cleaning or replacing filter 4, simply reinstall the bottom cover 2.
[0044] When the fan assembly 7 needs to be replaced, first remove the top cover 1 to expose the air duct 6, then remove the fan assembly 7 from the air duct 6 for cleaning and maintenance. Alternatively, invert the air purifier, first remove the bottom cover 2 to remove the filter 4, then pull the air guide grille 5 out from the side wall 3. With the air purifier inverted, pull the air guide grille 5 out from bottom to top, and finally remove the fan assembly 7 from the air duct 6 for cleaning and maintenance. With the air purifier inverted, remove the fan assembly 7 from bottom to top.
[0045] The connection between the air guide grille 5 and the side wall 3 is provided with mutually cooperating elastic clips and fasteners. This allows the air guide grille 5 to be pulled out from the side wall 3 of the air purifier housing, or to be pushed into the air purifier housing and locked in place with the side wall 3. The pulling / pushing direction of the air guide grille 5 is parallel to the extension direction of the side wall 3. The specific elastic clips and fasteners can adopt conventional snap-fit structures found in existing technology; those skilled in the art can choose according to their needs, and will not be elaborated upon here.
[0046] In a preferred embodiment, such as Figures 3-4 As shown, a horizontally protruding card block 12 is provided at one end of the top cover 1, and a card slot 32 that is inserted into the card block 12 is provided horizontally at the top of the side wall 3; a first magnetic suction member 13 is provided at the other end of the top cover 1 opposite to the card block 12, and a second magnetic suction member 33 corresponding to the first magnetic suction member 13 is provided at the top of the side wall 3.
[0047] When it is necessary to remove the top cover 1, first lift one end of the top cover 1 with the first magnetic 13 upwards so that the first magnetic 13 separates from the second magnetic 33, and then move the top cover 1 laterally so that the card block 12 disengages from the card slot 32, thereby removing the top cover 1.
[0048] In a preferred embodiment, such as Figure 3 As shown, a sensor switch 34 is installed at the connection between the top cover 1 and the top of the side wall 3. The sensor switch 34 is used to detect whether the top cover 1 is installed correctly. When the top cover 1 is removed, the air purifier automatically cuts off the power to ensure user safety; when the top cover 1 is installed in place, the air purifier can operate normally after being powered on.
[0049] In a preferred embodiment, such as Figures 5-6 As shown, the air duct 6 extends radially from its inner peripheral wall towards the center with several support frames 61. Receiving grooves 62 are provided at the intersections of the support frames 61, and groove covers 63 are provided at the upper openings of the receiving grooves 62. Specifically, the air duct 6 is cylindrical in shape, with openings at both ends for airflow. Several support frames 61 extend from the inner peripheral wall of the air duct 6 towards the center to fix the fan assembly 7. Receiving grooves 62 are provided at the intersections of the support frames 61 to fix the motor 71, and a fan wheel 72 is installed on the motor 71. Groove covers 63 are provided at the openings of the receiving grooves 62 to prevent the motor 71 from being exposed to the top cover 1 of the air purifier, as this would affect the aesthetics if the user could see the fan assembly 7 from the top cover 1.
[0050] In a preferred embodiment, such as Figure 6 As shown, the groove cover 63 has downwardly extending side ears 631 around its periphery, and a window 632 is provided on the side ears 631. The inner peripheral wall of the receiving groove 62 is provided with a protrusion 621 corresponding to the window 632. When it is necessary to disassemble the fan assembly 7, the groove cover 63 needs to be removed first. At this time, it is only necessary to pull out the groove cover 63 forcefully to disengage the window 632 on the side ear 631 from the protrusion 621. When installing the groove cover 63, it is only necessary to press the groove cover 63 forcefully to make the window 632 on the side ear 631 cooperate with the protrusion 621 and secure it. The operation is simple and convenient.
[0051] In a preferred embodiment, such as Figure 6 As shown, the periphery of the slot cover 63 is also provided with a groove 633, and the inner peripheral wall of the receiving groove 62 is provided with ribs 622 corresponding to the groove 633. The side ears 631 are distributed at intervals with the groove 633. This embodiment adds a way for the groove 633 on the slot cover 63 to cooperate and fix with the ribs 622 on the receiving groove 62, and adopts the method of the side ears 631 and the groove 633 being distributed at intervals, further improving the stability of the connection between the slot cover 63 and the receiving groove 62.
[0052] In a preferred embodiment, such as Figure 7As shown, the fan assembly 7 includes a motor 71 and a fan wheel 72 fixed to the shaft of the motor 71. The motor 71 is disposed within a receiving groove 62, and the shaft of the motor 71 extends downward through the bottom wall of the receiving groove 62. The fan wheel 72 is fixed below the receiving groove 62. In this embodiment, fixing the motor 71 within the receiving groove 62 allows the receiving groove 62 to support the motor 71 upwards, making the motor 71 more stable. Fixing the fan wheel 72 below the receiving groove 62 brings the distance between the fan wheel 72 and the air guide grille 5 closer, resulting in better air guidance and lower noise.
[0053] It should be noted that in this embodiment, when the fan assembly 7 needs to be disassembled, it needs to be disassembled from both the top and bottom ends of the air purifier. Specifically, first, invert the air purifier, and then remove the bottom cover 2, filter 4, and air guide grille 5 from the bottom in sequence. Then, remove the impeller 72 from the shaft of the motor 71. Next, place the air purifier upright, remove the top cover 1 from the top, remove the slot cover 63, and then remove the motor 71 from the top of the receiving slot 62, thus completing the disassembly of the fan assembly 7. If only the impeller 72 on the fan assembly 7 needs to be cleaned and maintained without replacing the motor 71, simply invert the air purifier, and then remove the bottom cover 2, filter 4, and air guide grille 5 from the bottom in sequence. Finally, remove the impeller 72 from the shaft of the motor 71.
[0054] In a preferred embodiment, such as Figure 7 As shown, a motor mounting bracket 73 is fixed to the bottom wall of the receiving groove 62, and the motor 71 is fixed to the motor mounting bracket 73. A vibration damping pad 74 is provided between the motor mounting bracket 73 and the bottom wall of the receiving groove 62. The design of the vibration damping pad 74 can reduce the vibration of the motor 71 and reduce noise.
[0055] In a preferred embodiment, such as Figure 8 As shown, the air guide grille 5 is a flat plate with a certain thickness. The periphery of the air guide grille 5 is snapped to the side wall 3. The air guide grille 5 is recessed from the periphery to the center along the thickness direction to form an arc surface 51. The lowest point of the arc surface 51 is flush with the bottom surface of the air guide grille 5. In this embodiment, the thickness direction of the air guide grille 5 is parallel to the side wall 3, which is the height direction of the air purifier. The lowest point of the arc surface 51 is flush with the bottom surface of the air guide grille 5. That is, when the air guide grille 5 and the filter 4 are installed in place, the lowest point of the arc surface 51 is exactly located at the top of the cavity of the filter 4. This can maximize the overall height of the air purifier while ensuring that there is space between the fan assembly 7 and the arc surface 51, so that the air is fully guided and noise is reduced.
[0056] In a preferred embodiment, such as Figure 9As shown, the bottom cover 2 includes a connecting bracket 21 and a base 22. The connecting bracket 21 is annular and is used to fix it to the bottom of the side wall 3. The base 22 is located inside the connecting bracket 21. One end of the base 22 is inserted into the connecting bracket 21, and the other end of the base 22 is connected to the connecting bracket 21 through a locking assembly 23. The base 22 is used to support the filter 4. In this embodiment, the bottom cover 2 includes a detachable connecting bracket 21 and a base 22. The connecting bracket 21 is connected to the side wall 3 of the air purifier, and the base 22 supports the filter 4. When the filter 4 needs to be removed for replacement or cleaning, only the base 22 needs to be removed to remove the filter 4. It is not necessary to disassemble the side wall 3 or the connecting bracket 21, thus avoiding damage to the connection structure between the side wall 3 and the connecting bracket 21. This ensures the integrity and aesthetics of the overall structure of the air purifier and avoids the problem of the side wall 3 being completely or partially disassembled, deforming the connection position, and creating gaps, which would ultimately lead to the instability of the overall structure. Figure 10 As shown, a portion of the locking assembly 23 is exposed at the bottom of the base 22, allowing the user to directly disassemble the base 22 from the bottom of the air purifier. That is, by pressing the handle of the exposed part, the locking assembly 23 can be unlocked, allowing the base 22 to separate from the connecting bracket 21, thereby removing the filter 4.
[0057] The detachable air purifier provided by this utility model allows for the individual removal of components such as the bottom cover 2, filter 4, air guide grille 5, impeller 72 of the fan assembly 7, motor 71 of the fan assembly 7, and top cover 1. This facilitates cleaning and maintenance of each component, improves the overall performance of the air purifier, and extends its service life. Figure 11 The diagram shown illustrates the disassembly steps of an air purifier according to one embodiment. Figure 11 The three sides of the sidewall are hidden to make the disassembly diagram more intuitive; among them, Figure (a) is a diagram after removing the bottom cover 2, Figure (b) is a diagram after removing the filter 4, Figure (c) is a diagram after removing the air guide grille 5, Figure (d) is a diagram after removing the impeller 72, Figure (e) is a diagram after removing the top cover 1, and Figure (f) is a diagram after removing the motor 71.
[0058] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0059] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
