[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a humidifier, comprising: a base 10; an air outlet 20 disposed on the base 10, the upper end of the air outlet 20 having an air outlet 21; a cylinder 30, the lower end of the cylinder 30 being connected to the upper end of the air outlet 20, the upper end of the cylinder 30 having an opening; a sealing member 40 movably disposed within the cylinder 30; a water tank 50 detachably connected to the base 10; and a pushing part 60 disposed at the bottom of the water tank 50; wherein, when the water tank 50 and the base 10 are separated, the pushing part 60 is located outside the cylinder 30, and the sealing member 40 blocks the air outlet 21; when the water tank 50 and the base 10 are connected, the pushing part 60 extends into the cylinder 30 and pushes the sealing member 40 to move, thereby forming a gap between the air outlet 20 and the sealing member 40.

[0025] Using this design, during the installation and removal of the water tank 50, the pushing part 60 located at the bottom of the water tank 50 can move the sealing element 40, thereby opening or blocking the air outlet 21. This design has a simple structure, which reduces costs and is easy to operate. The gap formed between the air outlet 20 and the sealing element 40 can also be understood as opening the air outlet 21, allowing ventilation.

[0026] The pushing part 60 can be fixedly connected to the bottom of the water tank 50 or movably connected to the bottom of the water tank 50. The bottom of the water tank 50 has a groove, and the pushing part 60 is disposed in the groove. When the pushing part 60 and the water tank 50 are fixedly connected, the entire pushing part 60 is located in the groove to prevent the lower end of the pushing part 60 from protruding from the bottom surface of the water tank 50, thus facilitating the placement of the water tank 50.

[0027] In this embodiment, the base 10 has a water tank, and cavities are spaced apart below the water tank. A fan is located inside the cavity, and the air outlet duct 20 is connected to the cavity, with the fan supplying air to the air outlet duct 20. By providing a sealing element 40, the air outlet 21 can be blocked, thus preventing water from entering the air outlet duct 20 and the fan when water is added to the water tank.

[0028] Specifically, in this embodiment, the pushing part 60 is rotatably disposed at the bottom of the water tank 50, and the cylinder 30 has a conical structure, with the lower end of the cylinder 30 having a smaller opening and the upper end having a larger opening. Thus, the inner wall of the cylinder 30 is inclined. During the installation of the water tank 50, the pushing part 60 moves downwards, contacts the inner wall of the cylinder 30, and rotates. During this rotation, the pushing part 60 contacts the sealing element 40 and pushes the sealing element 40 to move, thereby forming a gap between the air outlet 20 and the sealing element 40, i.e., opening the air outlet 21.

[0029] Optionally, the projection on the horizontal plane shows the pushing part 60 located inside the upper opening of the cylinder 30. This ensures that the pushing part 60 automatically falls into the cylinder 30 during the installation of the water tank 50, facilitating operation.

[0030] In this embodiment, the pushing part 60 includes: a push rod 61, the upper end of which engages with the water tank 50; and a ball head 62, disposed at the lower end of the push rod 61. When the water tank 50 and the base 10 are connected, a portion of the push rod 61 and the ball head 62 extend into the air outlet pipe 20. The push rod 61 can drive the ball head 62 to move. By providing the ball head 62, resistance can be reduced, making it easier to insert the ball head 62 between the air outlet pipe 20 and the sealing member 40, thus creating a gap for air outlet between the air outlet pipe 20 and the sealing member 40.

[0031] Specifically, during the installation of the water tank 50, the push rod 61 and the ball head 62 push the seal 40 to roll along the inner wall of the cylinder. The seal 40 moves upward during rotation, thus no longer blocking the air outlet 21. When the water tank 50 and the base 10 are separated, the push part 60 is located outside the cylinder 30. Optionally, the ball head 62 is made of rubber.

[0032] In this embodiment, the pushing unit 60 further includes a rotating shaft 63, which is rotatably mounted on the water tank 50, and the upper end of the push rod 61 is connected to the rotating shaft 63. This arrangement facilitates smooth rotation of the push rod 61.

[0033] In this embodiment, the water tank 50 has a downward-facing groove 51, and a support 52 is located within the groove 51. The rotating shaft 63 is hinged to the support 52. The support 52 supports and limits the rotation shaft 63.

[0034] In this embodiment, the seal 40 is a spherical structure, and the air outlet duct 20 is a circular tube. The diameter of the seal 40 is larger than the inner diameter of the air outlet duct 20. Setting the seal 40 as a spherical structure reduces resistance, facilitates movement, and effectively seals the air outlet 21. Specifically, the seal 40 is made of rubber, resulting in a good sealing effect.

[0035] In this embodiment, the side wall of the cylinder 30 has a water inlet groove 31, which connects the inside and outside of the cylinder 30. In this way, water entering the cylinder 30 can flow to the outside of the cylinder 30 through the water inlet groove 31, which can prevent water from accumulating inside the cylinder 30, and further prevent water from entering the air outlet duct 20.

[0036] In this embodiment, the cylinder 30 has a conical structure, and the water inlet trough 31 has a spiral structure. This facilitates the downward flow of water on the inner wall of the cylinder 30 and the flow to the outside of the cylinder 30.

[0037] In this embodiment, the air outlet duct 20 is vertically arranged, and the upper end face of the air outlet duct 20 has an annular groove 22. In the projection on the horizontal plane, the inner periphery of the lower end of the cylinder 30 is located in the annular groove 22. In this way, when there is water on the inner wall of the cylinder 30, the water can drip into the annular groove 22 and will not enter the interior of the air outlet duct 20, thereby preventing water from entering the air outlet duct 20.

[0038] Furthermore, the side wall of the air outlet duct 20 has a drain port 23, which connects the annular groove 22 and the outside of the air outlet duct 20. Water in the annular groove 22 can be drained through the drain port 23, preventing excessive water accumulation in the annular groove 22.

[0039] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0040] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
