Detailed Implementation

[0030] 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.

[0031] Example 1:

[0032] Embodiment 1 of this utility model provides a water-blocking structure for an air outlet. Please refer to [link / reference]. Figures 2-6 The humidifier includes: a sleeve 5, which is fixed to the top of the air outlet cover 4. The top surface of the sleeve 5 is open 501, and the bottom surface has a through hole 502 in the middle; a water baffle 6 is slidably sleeved on the air outlet cover 4, and its top wall abuts against the upper bracket 2 of the humidifier; the side wall 602 of the water baffle 6 has an opening 601 corresponding to the air outlet 401 of the air outlet cover 4, and the side wall 602 below the opening 601 can cover the corresponding air outlet 401; the top of the elastic structure 7 is connected to the top wall of the water baffle 6, and the bottom extends into the sleeve 5 and is connected to a sealing member 8. The bottom surface of the sealing member 8 covers the through hole 502 and abuts against the bottom surface of the sleeve 5.

[0033] In use, the upper bracket 2 is fixed to the top of the humidifier body 1, and the top of the water baffle 6 abuts against the bottom surface of the upper bracket 2. At this time, the elastic structure 7 is in a compressed state, and the opening 601 on the water baffle 6 corresponds to the air outlet 401 on the three sides of the air outlet 4. When the fan 3 is running, the air can be blown out normally through the air outlet 401 and the opening 601. When it is necessary to clean or add water to the inside of the humidifier body 1, the upper bracket 2 is first removed from the top of the humidifier body 1. The elastic structure 7 is then released from its constraint. Under the action of its own rebound force, it drives the water baffle 6 to move upward until the sealing part 8 abuts against the bottom surface of the sleeve 5. At this time, the side wall 602 below the opening 601 of the water baffle 6 blocks the corresponding air outlet 401, and the elastic structure 7 is still in a compressed state.

[0034] With this solution, when it is necessary to clean or add water to the inside of the humidifier body 1, the water baffle 6 and the elastic structure 7 can block the air outlet 401 on the air outlet cover 4, making it difficult for water to enter the fan 3 and other electrical components through the air outlet 401, thereby significantly reducing the adverse effects on the electrical components.

[0035] Further optimization of the scheme: the elastic structure 7 includes an installation body 71 fixedly connected to the top wall of the water baffle 6, the bottom of the installation body 71 extends into the sleeve 5 and is connected to the sealing member 8; an elastic member 72 is provided on the installation body 71, the top of the elastic member 72 abuts against the installation body 71, and the bottom abuts against the inner bottom wall of the sleeve 5.

[0036] In this first embodiment, when the upper bracket 2 is fixed to the top of the humidifier body 1 or removed from the top of the humidifier body 1, the elastic element 72 is always in a compressed state, and when the upper bracket 2 is fixed, the compression of the elastic element 72 is greater than the compression when the upper bracket 2 is removed; when the upper bracket 2 is removed, the rebound force generated by the elastic element 72 is sufficient to support the water baffle 6 and the mounting body 71, that is, without the action of other external forces, the side wall 602 below the opening 601 of the water baffle 6 will stably block the corresponding air outlet 401.

[0037] In a further optimized design, the mounting body 71 includes a ring 711 that is fixed to the top of the water baffle 6, with the bottom of the ring 711 extending into the sleeve 5; a rod 712 is fixedly connected to the inner wall of the ring 711, with the bottom of the rod 712 extending below the ring 711 and connected to the sealing member 8; an elastic member 72 is sleeved on the outer periphery of the rod 712, and its top abuts against the top of the rod 712.

[0038] In this first embodiment, the cross-section of the rod 712 is a T-shaped structure, and the top of the rod 712 is provided with a weight-reducing groove 7120 to reduce the weight of the rod 712 itself; the elastic element 72 is set as a compression spring, the top of the compression spring abuts against the top of the rod 712, and the bottom of the compression spring abuts against the inner bottom wall of the sleeve 5; there is a gap between the ring 711 and the opening 501 on the top surface of the sleeve 5.

[0039] The design was further optimized by setting the sealing component 8 as a screw with a connecting thread. The bottom of the rod 712 has a threaded hole that matches the thread of the screw with a connecting thread, and the screw with a connecting thread is threaded into the threaded hole at the bottom of the rod 712. By setting the screw with a connecting thread, the sealing effect on the through hole 502 can be improved.

[0040] It should be noted that the threaded hole and the weight reduction groove 7120 are not connected in this utility model.

[0041] Example 2

[0042] like Figure 7 As shown, based on the above embodiment one, the difference between this embodiment two and the above embodiment one is that: in this embodiment two, a sealing ring 9 is provided at the gap between the ring body 711 and the opening 501 on the top surface of the sleeve 5, and the ring body 711 slides and seals with the sleeve 5 through the sealing ring 9.

[0043] Specifically, the top surface of the sleeve 5 is provided with an installation groove, the sealing ring 9 is installed in the installation groove and fixed by the pressure block 10. The pressure block 10 and the sleeve 5 are detachably connected by multiple bolts, and the top surface of the pressure block 10 is flush with the top surface of the sleeve 5. The pressure block 10 and the installation groove enable the detachable connection of the sealing ring 9. The sealing element can seal the gap between the ring body 711 and the opening 501 on the top surface of the sleeve 5. Compared with the above embodiment 1, when cleaning or adding water to the inside of the humidifier body 1, water can be prevented from entering the inside of the sleeve 5 through the gap between the ring body 711 and the opening 501 on the top surface of the sleeve 5.

[0044] Finally, it should be noted that: the above embodiment one is only used to illustrate the technical solution of this utility model, and not to limit it; although this utility model has been described in detail with reference to the foregoing embodiment one, those skilled in the art should understand that: modifications can still be made to the technical solutions described in the foregoing embodiment one, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments one of this utility model.
