[0032] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a humidifier, which at least includes: a water tank assembly 1, a base 2, an atomizing device, a fan 3 and a circuit board. The water tank assembly 1 is assembled on the base 2, and the water tank assembly 1 is used to hold water. The base 2 includes: a bottom shell 21 and a bottom plate 22. The bottom shell 21 and the bottom plate 22 form an internal cavity after assembly. The circuit board and the fan 3 are installed in the internal cavity of the base 2. A water tank 224 is provided on the bottom plate 22. The atomizing device is provided at the bottom of the water tank 224 and is electrically connected to the circuit board. The water tank 224 is connected to the water tank assembly 1 through a water valve assembly, so that the water in the water tank assembly 1 can be introduced into the water tank 224, so that the atomizing device can atomize the water. An air outlet pipe 221 connected to the water tank 224 is provided throughout the water tank assembly 1, and the air outlet pipe 221 forms a mist outlet 11 at the top of the water tank assembly 1.

[0033] like Figure 2 , Figure 4 and Figure 7 As shown, an air outlet 222 is also provided on the bottom plate 22, and the air outlet 222 is used to blow the air flow provided by the fan 3 into the water tank 224 and discharge it through the air outlet pipe 221, so as to discharge the water mist and achieve an atomization effect.

[0034] like Figure 2 As shown, a waterproof device 4 is also provided on the bottom plate 22, and the waterproof device 4 is provided between the base 2 and the water tank assembly 1, and the waterproof device 4 can be used to block the air outlet 222 on the base 2. Specifically, when the water tank assembly 1 is installed on the base 2, the waterproof device 4 is in a state of not blocking the air outlet 222, so as to ensure normal ventilation of the air outlet 222; when the water tank assembly 1 is removed from the base 2, the waterproof device 4 is in a state of blocking the air outlet 222, and when the base 2 is cleaned, water is effectively prevented from entering the internal cavity hole of the base 2 through the air outlet 222, thereby preventing water from damaging the circuit board.

[0035] Specifically, Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the waterproof device 4 includes: a movable column 41 movably arranged on the base 2, a waterproof door 42 arranged on the movable column 41 and used to block the air outlet 222, and a stopper 43 arranged on the base 2 and used to keep the waterproof door 42 at the position of blocking the air outlet 222. The movable column 41 has a guiding function, which is used to ensure the installation of the waterproof door 42 and the stability when it is in different positions. The stopper 43 is used to provide a power to keep the waterproof door 42 blocking the air outlet 222, so as to ensure the blocking effect of the waterproof door 42.

[0036] The waterproof device 4 provided in the embodiment of the present invention has a waterproof door 42 that is movably arranged on the base 2 through a movable column 41, so that the waterproof door 42 can be stably in two states: blocking the air outlet 222 and not blocking the air outlet 222. Then, the waterproof door 42 is enabled to block the air outlet 222 when no external force is applied through a limiting member 43, thereby effectively preventing water from entering the interior of the base 2 through the air outlet 222 when the base 2 is cleaned, thereby improving the cleaning efficiency and safety of the humidifier.

[0037] Specifically, Figure 4 and Figure 7As shown, in this embodiment, an air outlet pipe 221 is provided on the base 2, and the air outlet 222 is provided on the side of the air outlet pipe 221. The waterproof door 42 is attached to the side of the air outlet pipe 221 having the air outlet 222. A hollow guide cylinder 223 is provided on the base 2 located on the side of the air outlet 222. The movable column 41 is movably arranged in the guide cylinder 223, and the limiting member 43 is arranged in the guide cylinder 223. When no external force is applied, the limiting member 43 drives the movable column 41 to move in the axial direction away from the guide cylinder 223, so that the waterproof door 42 blocks the air outlet 222.

[0038] Specifically, in this embodiment, the air outlet pipe 221 is a square pipe, and the air outlet 222 is arranged at one end of the air outlet pipe 221 away from the surface of the bottom shell 21, so that there is a distance between the air outlet 222 and the surface of the bottom shell 21, which is used to prevent water on the surface of the bottom shell 21 from overflowing into the air outlet 222. The guide cylinder 223 is used to install the movable column 41, and has a positioning function, so that the waterproof door 42 is always attached to the side of the air outlet pipe 221 with the air outlet 222, so as to ensure the effect of the waterproof door 42 blocking the air outlet 222. The limiter 43 is arranged in the guide cylinder 223, which has the advantage of easy installation.

[0039] More specifically, if Figure 4 As shown, in one implementation of this embodiment, the limiting member 43 is a spring, one end of the spring abuts against the bottom of the guide cylinder 223 , and the other end of the spring abuts against the movable column 41 .

[0040] like Figure 2 and Figure 4 As shown, when the water tank assembly 1 is removed from the base 2, the elastic force of the spring itself ejects the movable column 41 in a direction away from the bottom shell 21, thereby driving the waterproof door 42 to block the air outlet 222 through the movable column 41, so as to quickly clean the base 2. Figure 6 As shown (water tank assembly 1 is omitted, and the actual water tank is installed on the base 2), the bottom of the water tank assembly 1 is pressed against the movable column 41. Due to the deadweight of the water tank assembly 1, the movable column 41 is accommodated in the guide cylinder 223. At this time, the spring is compressed, and the movable column 41 drives the waterproof door 42 to move toward the bottom plate 22, so that the waterproof door 42 moves downward and away from the air outlet 222, ensuring that the air outlet 222 is in a ventilated state, and achieving the smoothness of the humidifier's air outlet. When the water tank assembly 1 is removed from the base 2, the spring returns to the uncompressed state, and drives the movable column 41 to move in the direction away from the base 2, so that the waterproof door 42 blocks the air outlet 222, and this cycle is repeated without additional operation, which is simple and practical, and has a good waterproof effect.

[0041] In another embodiment of the present embodiment, the stopper 43 includes: two mutually repelling permanent magnets, one permanent magnet is arranged at the bottom of the guide cylinder 223, and the other permanent magnet is arranged on the movable column 41. The two mutually repelling permanent magnets are used to increase the effective use time of the stopper 43, and effectively ensure the stability of the waterproof door 42 in blocking the air outlet 222. Of course, in other embodiments, the stopper 43 can also be a buckle structure.

[0042] Specifically, Figure 4 and Figure 7 As shown, a guide column 2231 for the spring to be sleeved is provided in the guide cylinder 223, and a blind hole 411 for accommodating the spring and for the guide column 2231 to be inserted is provided on the movable column 41. The guide column 2231 is convenient for installing the spring and keeping the spring in a straight line state in a compressed or uncompressed state, and the blind hole 411 cooperates with the guide column 2231, which has a good effect on keeping the spring in a straight line state.

[0043] Specifically, Figure 4 , Figure 5 and Figure 7 As shown, a guide groove 2232 is provided on the side wall of the guide cylinder 223 near the air outlet 222, and the movable column 41 and the waterproof door 42 are connected by a guide plate 44 penetrating the guide groove 2232, and the guide plate 44 can move along the extension direction of the guide groove 2232. The setting of the guide groove 2232 can be used to limit the movement of the guide plate 44, prevent the movable column 41 and the waterproof door 42 from deflecting their positions, so that the waterproof door 42 always faces the air outlet 222 and blocks it.

[0044] Specifically, Figure 4 and Figure 8 As shown, in this embodiment, a limiting cover 5 is provided on the air outlet pipe 221, and a U-shaped groove 521 is provided on the limiting cover 5 located above the air outlet 222, and the limiting member 43 drives one end of the waterproof door 42 to be assembled in the U-shaped groove 521 to block the air outlet 222. The U-shaped groove 521 is assembled with the waterproof door 42 to form a double seal on the upper part and both sides of the waterproof door 42, and the U-shaped groove 521 also has a limiting function, which is used to stably install the movable column 41 on the base 2, and to prevent the movable column 41 from being separated from the guide cylinder 223 under the drive of the limiting member 43, so that the waterproof door 42 cannot face and block the air outlet 222. The limiting cover 5 is detachably arranged on the air outlet pipe 221, so as to facilitate the installation and removal of the waterproof door 42. Specifically, the limiting cover 5 is fixed to the air outlet pipe 221 by screws, wherein the limiting cover 5 is provided with a stud, and a screw hole is provided at the top of the air outlet pipe 221, and the screw passes through the screw hole and is threadedly connected with the stud. Of course, the limiting cover 5 can also be fixed to the air outlet pipe 221 by a buckle.

[0045] More specifically, in one implementation of this embodiment, the limit cover 5 includes: three side panels 51 connected to each other and enclosed in a U shape, and a top panel 52 provided on the same end surface of the three side panels 51, a U-shaped groove 521 provided on the inner side of the top panel 52, and the three side panels 51 are respectively attached to the corresponding side surfaces of the air outlet pipe 221. In this embodiment, a side wall of the air outlet pipe 221 away from the air outlet 222 is arranged in an arc shape, which has a drainage effect on the wind flow, and effectively reduces the noise of the wind flow directly hitting the side wall of the air outlet pipe 221.

[0046] Among them, there is a distance between the lower end surface of the limit cover 5 (that is, the other same end surface of the three side panels 51) and the surface of the bottom shell 21, that is, the lower end surface of the limit cover 5 is higher than the surface of the bottom shell 21, thereby effectively preventing water from gathering and climbing through the gap into the air outlet 222, thereby realizing the waterproof function during cleaning.

[0047] Specifically, Figure 4 and Figure 8 As shown, the two opposite side plates 51 are provided with a bent edge 53 at one end close to the air outlet 222, and a limiting groove 54 is formed between the bent edge 53 and the side wall of the air outlet pipe 221, and the waterproof door 42 is partially accommodated in the limiting groove 54. The limiting groove 54 cooperates with the U-shaped groove 521 to achieve double sealing on both sides of the waterproof door 42.

[0048] Specifically, Fig. 9 As shown, in another embodiment of the present embodiment, the limiting cover 5 is a limiting plate, which is detachably arranged on the top of the air outlet pipe 221, and the U-shaped groove 521 is arranged on the side of the limiting plate close to the air outlet 222. Setting the limiting cover 5 as a limiting plate has the advantage of saving materials while ensuring its limiting and waterproofing functions. Specifically, the limiting plate is connected to the top of the air outlet pipe 221 by screws; wherein, a stud is provided on the limiting plate, and a screw hole is provided on the top of the air outlet pipe 221, and the screw passes through the screw hole and is threadedly connected to the stud.

[0049] In this embodiment, the waterproof door 42, the guide plate 44 and the movable column 41 are integrally formed and made of plastic material. The base 2 and the water tank assembly 1 are also injection molded of plastic material.
