[0025] The components include: housing 10, mounting cavity 11, positioning protrusion 12, guide slope 121, limiting slot 13, guide arc surface 14, support surface 15, second limiting groove 16, arc-shaped recess 17, fan assembly 20, cavity 21, first limiting groove 22, eaves 23, limiting protrusion 24, locking block 30, limiting block 31, and top bead 40. Detailed Implementation

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] In a first aspect, embodiments of this application provide a mounting structure for a fan assembly, used in a humidifier, such as... Figure 1 As shown, the mounting structure includes a housing 10 and a fan assembly 20, as well as a locking structure disposed between the housing 10 and the fan assembly 20. The housing 10 has a mounting cavity 11 with a top opening; the fan assembly 20 is assembled into the mounting cavity 11 through the top opening of the mounting cavity 11. The locking structure includes a plurality of corresponding locking blocks 30 and a plurality of positioning protrusions 12. The plurality of locking blocks 30 are circumferentially spaced on the outer side wall of the fan assembly 20, and the locking blocks 30 can move radially and telescopically relative to the fan assembly 20. The plurality of positioning protrusions 12 are circumferentially spaced on the cavity wall of the mounting cavity 11.

[0028] The fan assembly 20 can rotate horizontally relative to the housing 10, allowing the locking block 30 to switch between a first position and a second position relative to the positioning protrusion 12. That is, the locking structure has a locked state and an unlocked state. The locking block 30 is in the locked state when it is in the first position and in the unlocked state when it is in the second position. Specifically, when the locking block 30 is in the first position, it can retract radially inward under the action of a spring and then spring back to lock with the positioning protrusion 12 to fix the housing 10 and the fan assembly 20. When the fan assembly 20 rotates relative to the housing 10 in a predetermined direction and at a predetermined angle to move the locking block 30 to the second position, the locking block 30 disengages from the positioning protrusion 12.

[0029] During installation, the fan assembly 20 is first placed into the mounting cavity 11 through the opening at the top of the housing 10. As the fan assembly 20 descends, the locking block 30 contacts the positioning protrusion 12. Under the action of the spring, the locking block 30 retracts radially into the housing 10 until the fan assembly 20 continues to descend to the predetermined position, i.e., the first position. At this time, the locking block 30 on the fan assembly 20 is locked in place with the positioning protrusion 12 on the housing 10, thus achieving a fixed connection between the fan assembly 20 and the housing 10. During disassembly, the fan assembly 20 is simply rotated relative to the housing 10 in a predetermined direction, such as clockwise or counterclockwise, until the locking block 30 moves to the second position and disengages from the positioning protrusion 12. Then, the fan assembly 20 can be easily removed from the mounting cavity 11.

[0030] In this way, by cooperating with the positioning protrusion 12 and the locking block 30, compared with setting a relief groove on the cavity wall of the mounting cavity 11 corresponding to the position of the locking block 30, the wall thickness of the housing 10 can be greatly reduced, and the positioning protrusion 12 protruding outside the cavity wall of the mounting cavity 11 can provide a larger contact area, thereby ensuring the stability and reliability of the locking and avoiding the problem of loosening or falling off due to insufficient contact area.

[0031] In some embodiments, the cavity wall of the mounting cavity 11 is provided with a plurality of limiting slots 13, which are arranged adjacent to the lower part of the positioning protrusion 12. When the locking block 30 is in the first position, it extends into the limiting slot 13, and when the locking block 30 moves to the second position, it disengages from the limiting slot 12. Figure 3 , Figure 8 As shown, the limiting slot 13 is located directly below the positioning protrusion 12. When the locking block 30 rebounds radially outward under the action of the spring and locks tightly with the positioning protrusion 12 on the housing 10, when the user rotates the fan assembly 20, at least part of the locking block 30 extends into the limiting slot 13. At this time, the user can clearly feel the change in rotational resistance, thus clearly perceiving that the fan assembly 20 has been installed in place. This tactile feedback mechanism provides the user with a clear signal that the installation is in place. Furthermore, the limiting slot 13 can further limit the loosening or separation between the locking block 30 and the positioning protrusion 12 caused by the slight rotation of the fan assembly 20 in the working state, thereby further improving the reliability and stability of the connection.

[0032] In some embodiments, such as Figure 3 , Figure 8As shown, the limiting latch 13 has a guide arc surface 14 that abuts against the latch 30; the guide arc surface 14 is used to guide the latch 30 to switch between the first position and the second position. The design of the guide arc surface 14 provides a smooth transition path for the latch 30 to switch between the first position and the second position, avoiding sudden collisions or jamming of the latch 30 during movement. The depth of the limiting latch 13 gradually increases from the first position to the second position, that is, the depth of the limiting latch 13 is the greatest in the first position, which can more firmly restrict the latch 30. When the user tries to rotate the fan assembly 20 in the wrong direction, that is, in an unexpected disassembly direction, the latch 30 will be blocked by the deeper part of the limiting latch 13, generating a noticeable resistance. This resistance serves as a warning, reminding the user of the incorrect operation direction and avoiding damage to components or safety hazards caused by misoperation. In addition, the design of the guide arc surface 14 allows the block 30 to smoothly reach the first position and cooperate with the positioning protrusion 12 from the second position when the fan assembly 20 is placed in the mounting cavity 11, which is simple and efficient.

[0033] In some embodiments, a plurality of clips 30 are arranged circumferentially and evenly at intervals on the outer side wall of the fan assembly 20. For example... Figure 2 , Figure 4 As shown, four card blocks 30 are set at the corresponding positions of card blocks 30. This can improve the reliability of the connection. Even if one card block 30 fails or is damaged, the other card blocks 30 can still provide sufficient connection force to ensure that the wind turbine assembly 20 will not fall off.

[0034] In some embodiments, such as Figure 3 , Figure 8 As shown, the positioning protrusion 12 has a guide ramp 121 extending from its top to its bottom, the top of which smoothly transitions with the cavity wall of the mounting cavity 11. In this embodiment, the main function of the guide ramp 121 is to guide the locking block 30 to smoothly slide into the engagement position with the positioning protrusion 12. That is, when the fan assembly 20 is installed into the mounting cavity 11 of the housing 10, the locking block 30 first contacts the guide ramp 121. As the fan assembly 20 descends, the locking block 30 gradually retracts inward along the guide ramp 121 until it passes the bottom of the positioning protrusion 12, and then springs back into place. This process is smooth and avoids rigid collision or jamming between the locking block 30 and the top of the positioning protrusion 12.

[0035] In some embodiments, such as Figure 4 , Figure 8As shown, the fan assembly 20 is provided with a cavity 21 for accommodating the locking block 30. The cavity 21 provides sufficient space for the movement of the locking block 30 and prevents the locking block 30 from interfering with other components. The locking block 30 is connected to the cavity 21 by a return spring (not shown), which provides the necessary elastic force for the extension and retraction of the locking block 30, ensuring that the locking block 30 can rebound to the initial position in time after being compressed by external force. A limiting block 31 is protruding from the surface of the locking block 30, and a first limiting groove 22 is provided on the cavity wall of the cavity 21 to prevent the limiting block 31 from falling out of the cavity 21, so as to ensure that it can only extend and retract in a predetermined direction, thereby avoiding the locking block from deviating or getting stuck during the movement and improving the reliability of the structure.

[0036] In some embodiments, such as Figure 2 , Figure 4 As shown, the top of the housing 10 has a support surface 15, and the top opening of the mounting cavity 11 is located on the support surface 15; the top edge of the fan assembly 20 extends outward to form an eave 23, which abuts against the support surface 15. The support surface 15 provides support for the eave 23 of the fan assembly 20, preventing the fan assembly 20 from being excessively inserted into the mounting cavity 11.

[0037] In some embodiments, such as Figure 3 , Figure 4 , Figure 6 As shown, a limiting protrusion 24 protrudes from the bottom surface of the eaves 23; the supporting surface 15 is provided with a second limiting groove 16 corresponding to the position of the limiting protrusion 24; the eaves 23, through the cooperation of the limiting protrusion 24 and the second limiting groove 16, limits the rotation angle of the fan assembly 20 relative to the housing 10. Thus, when the supporting surface 15 provides support for the eaves 23 of the fan assembly 20, the limiting protrusion 24 extends into the second limiting groove 16, forming a double limiting mechanism together with the previously mentioned limiting slot 13. Furthermore, the limiting protrusion 24 and the second limiting groove 16 can provide clear assembly orientation indicators for the fan assembly 20, thereby simplifying installation.

[0038] In some embodiments, such as Figure 3 , Figure 4 , Figure 8 As shown, the bottom surface of the eaves 23 is provided with multiple top beads 40 with built-in springs, and the top beads 40 protrude from the bottom surface of the eaves 23; the support surface 15 is provided with an arc-shaped recess 17 corresponding to the position of the top beads 40.

[0039] Specifically, the top ball 40 has a built-in spring. When the fan assembly 20 is installed onto the housing 10, the top ball 40 contacts the arc-shaped recess 17 on the support surface 15. Under the action of the spring, the top ball 40 can provide a certain buffering effect, reducing the rigid collision between the fan assembly 20 and the housing 10 and reducing the impact force. Furthermore, the top ball 40 with its built-in spring provides a soft tactile feedback during installation, improving the installation feel. When the top ball 40 slides into the arc-shaped recess 17, the user can feel a slight damping sensation and a "click" sound, thus obtaining a better operating experience. It can also help the user more accurately judge the installation position and improve installation efficiency. In this embodiment, the top ball 40 is a standard part, meaning that a compression spring and a top ball are built into the sleeve, with a small portion of the top ball protruding from the opening at the bottom of the sleeve.

[0040] Secondly, embodiments of this application provide a humidifier, including a mounting structure for a fan assembly as provided in any embodiment of the first aspect. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working process of the humidifier described above can be referred to the corresponding process in the aforementioned embodiments of the mounting structure for the fan assembly, and will not be repeated here.

[0041] The fan assembly mounting structure provided in this embodiment, through the cooperation of the locking block and the positioning protrusion, makes the installation and disassembly of the fan assembly extremely simple. Simply insert the fan assembly into the top opening of the housing mounting cavity and rotate it slightly. The locking block, under the action of the spring, retracts radially inward and then springs back to lock into the positioning protrusion, achieving a secure connection. Conversely, disassembly is easily achieved by rotating in the opposite direction, without the need for any tools, greatly improving assembly and maintenance efficiency. Simultaneously, the synergistic effect of the limiting slot and the limiting protrusion effectively limits the rotation angle of the fan assembly relative to the housing, preventing connection failure or component damage due to excessive rotation, further enhancing the reliability and stability of the connection. Furthermore, the design of the top ball and the arc-shaped recess not only provides a good cushioning feel during installation, improving the user experience, but also absorbs accidental impacts to a certain extent, protecting the housing and fan assembly from damage and extending the product's service life.
