[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] like Figure 1-4 The figure shows a humidifier capable of uniform humidification provided by this embodiment, comprising a housing 1, an air duct 2, a fan 3, a water tank 4 and an atomizer 6;

[0040] The housing 1 is a hollow shell structure, and a mist cavity 102 and an air cavity 104 connected by the air duct 2 are provided in the housing 1. An opening 101 connected to the mist cavity 102 is provided at the top of the housing 1, and an air inlet 103 connected to the air cavity 104 is provided at the bottom of the housing 1.

[0041] The atomizer 6 is connected to the water tank 4 and is used to atomize the medium in the water tank 4 and input it into the mist cavity 102;

[0042] The fan 3 is disposed in the air cavity 104 and is used to input the gas entering the air cavity 104 into the mist cavity 102 through the air duct 2;

[0043] The air duct 2 is arranged in the shell 1 at an angle along the peripheral direction of the shell 1, and is used to make the gas in the wind cavity 104 be input into the mist cavity 102 in a vortex shape; in this embodiment, the medium added to the water tank 4 is water; the atomizer 6 is an ultrasonic atomizer; the wind cavity 104 is arranged on the lower side of the interior of the shell 1, and is arranged on the lower side of the air duct 2; the opening 101 is arranged at the center of the top of the shell 1, and cooperates with the mist cavity 102 and the air duct 2 to achieve a relatively uniform wind force on the mist inside the mist cavity 102, so that the mist sprayed through the opening can form a spiral rising state; a detachable opening accessory with an air outlet can be provided at the opening 101, and the inner diameter of the air outlet of the opening accessory affects the diameter of the mist sprayed by the humidifier. According to actual usage requirements, opening accessories with different inner diameters can be installed at the opening 101 to improve the convenience of adjusting the mist diameter of the humidifier and the adaptability of the humidifier.

[0044] The humidifier disclosed in the present invention can humidify evenly. The humidifier changes the direction of the wind generated by the fan through an air duct obliquely arranged inside the shell, and cooperates with the opening on the top of the shell to make the wind entering the mist chamber produce a wind vortex phenomenon, that is, form a tornado shape, so that the mist in the mist chamber spirals up under the action of the wind vortex, and then makes the mist sprayed in all directions through the opening, thereby increasing the contact area between the sprayed mist and the air, increasing the area of ​​air humidification, and achieving a uniform humidification effect on the air, thereby improving the user's physical comfort.

[0045] In a specific embodiment, Figure 5 、 Figure 6 As shown, the water tank 4 is arranged in the housing 1;

[0046] The outer wall of the water tank 4 is also provided with a plurality of guide plates 8 arranged in a circumferential direction and an air duct outer plate 10 connected to the outer periphery of the guide plates 8; the outer wall of the water tank 4, the inner wall of the air duct outer plate 10 and the guide plates 8 form the air duct 2 to change the direction of the wind entering the mist cavity and cause the wind in the mist cavity to produce a vortex phenomenon, driving the mist to achieve a spiral rise of the mist, thereby achieving the effect of uniform humidification of the air; the shape of the cross section of the top of the water tank 4 is consistent with the cross section of the outer shell 1, and can be rectangular, circular or other shapes. In this embodiment, the outer shell 1 is a hollow cylinder; the guide plates 8 are arranged along the outer circumference of the water tank 4, and the surface of the guide plates 8 is set at 45° to the horizontal plane.

[0047] In a specific embodiment, an atomization chamber 401 is provided on the upper side of the water tank 4, and the atomizer 6 is installed in the atomization chamber 401. A power unit 5 is provided on the lower side of the water tank 4, and the power unit 5 is connected to the atomization chamber 401 via a pipeline. In this embodiment, the power unit 5 is a micro water pump; an ultraviolet light strip is installed in the pipeline to disinfect and sterilize the water source before it is transferred to the atomization chamber 401.

[0048] In a specific embodiment, the bottom inner wall and side wall of the outer shell 1 and the outer wall of the water tank 4 form the wind cavity 104; the outer wall of the water tank 4 is a wall structure whose size gradually decreases from the top periphery of the water tank 4 to the bottom center, that is, the cross-sectional area of ​​the water tank 4 gradually decreases from top to bottom. The shape of the outer wall of the water tank 4 is set so that the volume of the wind cavity 104 gradually decreases from bottom to top. The higher the wind pressure generated by the fan 3, the greater the wind force that drives the mist, and then cooperates with the air duct 2 and the opening 101 to make the mist better present a spiral rising effect, and improve the uniformity of humidification of the air by the humidifier.

[0049] In a specific embodiment, a water tank cover 9 is provided on the top of the water tank 4. A mist through hole 901 is provided on the water tank cover 9. The mist through hole 901 is connected to the atomization chamber 401 and the mist cavity 102.

[0050] The water tank cover 9 is further provided with a plurality of water leakage holes 902 communicating with the water tank 4, and the water leakage holes 902 are arranged outside the mist through hole 901;

[0051] The upper side of the water tank cover 9 is provided with a water retaining cover plate 7. Figure 9 As shown, the edge of the water retaining cover plate 7 is provided with a plurality of through holes 701, and the through holes 701 are connected with the mist through holes 901 and the mist cavity 102. When the atomizer 6 atomizes the water transported by the power unit 5 to the atomizing chamber 401, a large water flow may be generated and sprayed into the mist cavity 102, affecting the particle size of the generated mist droplets, thereby affecting the humidification effect on the air. The water retaining cover plate 7 provided directly blocks most of the large flow of water ejected by the atomizer 6 and causes the water flow to fall into the atomizing chamber 401. A small part of the water flow will be ejected through the through holes 701 of the water retaining cover plate 7 and fall onto the water tank cover 9 below the water retaining cover plate 7. The water falling on the water tank cover 9 enters the water tank 4 through the leaking hole 902 and becomes the water source of the power unit 5 and the atomizer 6 for atomization again. The water retaining cover plate 7 and the water tank cover 9 can prevent the generated mist from containing large-particle water droplets, thereby improving the atomization effect. In this embodiment, the water retaining cover plate 7 is detachably mounted on the mist through hole 901 via a threaded structure, which facilitates the removal and replacement of the water retaining cover plate 7 .

[0052] In a specific embodiment, a hollow shell-shaped vertical shell 402 is provided in the water tank 4, and the vertical shell 402 is vertically fixed to the lower side of the water tank cover 9; the upper side of the vertical shell 402 is provided with the atomization chamber 401, and the lower side of the vertical shell 402 is provided with a power device installation cavity 402a in which the power device 5 is installed; a wire harness through hole 402b is provided on the shell wall of the vertical shell 402. Figure 7 、 Figure 8As shown, the water tank 4 is provided with a wiring harness connection hole on the wall to facilitate the passage of the wiring harness for the atomizer 6 and the power unit 5. The vertical shell 402 provides installation space for the atomizer and the power unit. The wiring harness through hole 402b facilitates the use of a pipeline to connect the power unit 5 and the atomizer 6, thereby transporting the water in the water tank 4 to the atomization chamber 401, generating mist and realizing the humidification function of the humidifier.

[0053] In a specific embodiment, the housing 1 is provided with a water dispenser socket 108, and a pull-out water dispenser 15 is provided inside the housing 1. One end of the water dispenser 15 extends into the water tank 4, and the other end is located at the water dispenser socket 108. When water is added to the humidifier, an external force pulls out the water dispenser 15, and then water is added to the water tank of the water dispenser 15, and the water flows into the water tank 4. After the water is added, the water dispenser 15 is pushed back into the housing 1 by an external force, completing the water addition operation of the humidifier.

[0054] In a specific embodiment, the housing 1 includes a top cover 106, an intermediate housing 107, and a bottom housing 105. The intermediate housing 107 is disposed between the top cover 106 and the bottom housing 105. The opening 101 is disposed on the top cover 106. The intermediate housing 107, the top cover 106, and the water tank cover 9 form the mist chamber 102. The air chamber 104 is disposed within the bottom housing 105, and the air inlet 103 is disposed on the bottom wall of the bottom housing 105. In this embodiment, the intermediate housing 107 is made of a transparent acrylic sheet to enhance the user's visual experience and interactive experience.

[0055] In a specific embodiment, Figure 10 As shown, a limiting structure 14 is provided in the bottom housing 105, and the fan 3 is mounted on the limiting structure 14. The provision of the limiting structure 14 can improve the stability and firmness of the fan 3, prevent the vibration generated during operation of the fan 3 from causing instability of the fan 3, thereby affecting its working performance and lifespan, and also prevent the instability of the fan 3 from damaging other components.

[0056] In a specific embodiment, the housing 1 is further provided with a control switch 11 and an indicator light 12. The control switch 11 can be a touch switch or a probe induction switch for activating or deactivating the device. A sensor electrically connected to and corresponding to the control switch is provided within the housing. The principle of the sensor is known from the prior art and will not be further described here. In this embodiment, the control switch 11 is a probe induction switch capable of capturing motion. The housing 1 is also provided with a power connection port 13. A socket 20 corresponding to the position of the power connection port 13 is installed within the housing 1 for connecting the device to power.

[0057] Specifically, in this embodiment, the indicator light 12 can be designed as a LOGO style, and a light bulb is provided in the bottom shell 105 at the position corresponding to the indicator light 12; Figure 10 As shown, a transformer 16, a fuse 19 and a fan transformer 18 are also provided on the limiting structure 14 in the bottom shell 105; the transformer 16 is used to unify the voltage of various components; the fuse 19 is used to cut off the power in time when a circuit fault occurs; the fan transformer 18 is used to adjust the speed of the fan 3; a foot pad 17 is provided on the lower side of the outside of the bottom shell 105 to play an anti-slip role, improve the stability of the humidifier, and also provide a buffer to prevent the humidifier from damaging the surface on which it is placed;

[0058] When the user uses the humidifier, the switch instruction is conveyed to the probe sensing switch through gestures or other actions. After the probe captures the user's action, the product is started, and the fan 3, the atomizer 6, the power device 5 and the light bulb all start to run. The LOGO lights up and mist is generated. The wind generated by the fan 3 blows upward. Under the influence of the air duct 2, the direction of the wind is changed to an upward angle of forty-five degrees, and the opening 101 on the top cover plate acts at the same time to drive the mist, presenting a spiral upward effect of the mist in the middle shell 107. The mist is ejected from the opening 101 in a spiral upward to achieve uniform humidification of the air.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
