DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of the present application.

[0044] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the description of a particular example will not necessarily be repeated in each other example. Furthermore, the description is not intended to limit the present application to a particular example. In addition, the present application can use the same reference numbers in different examples to indicate the same or similar elements.

[0045] For the purpose of simplicity, spatial relative terms such as "inner", "outer", "inward", "outward", "lower", "bottom", "top", "upper", "front", "rear", and the like can be used in the description to describe the relative position or movement of one element or feature to another element or feature as shown in the figures.

The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0046] The atomizer (humidifier) is a common household appliance, widely used to improve indoor air quality, especially in dry seasons or environments.

[0047] The atomizer generally uses ultrasonic technology for atomization. The ultrasonic atomizers on the market are mainly divided into two types:

[0048] The first type: the atomizer without a designed air inlet cavity.

[0049] Features: this type of atomizer directly connects the fan outlet to the atomization cavity without a special air inlet cavity design.

[0050] Problem: Since the fan outlet is directly connected to the atomization chamber, there is a lack of proper airflow guidance, and the air flow inside the atomization chamber is chaotic, resulting in significant wind loss and atomization loss. Therefore, this design not only reduces the atomization efficiency, but also may affect the humidification effect, making it difficult for users to achieve the desired humidity level.

[0051] Second: The atomizer with a simple air inlet chamber.

[0052] Features: This type of atomizer designs the space between the box and the box cover as an air inlet chamber, and connects the air inlet chamber with the atomization chamber through a hole.

[0053] Problem: Although this design has improved compared to the first type, since the connection between the air inlet chamber and the atomization chamber is only a simple hole without a special air duct design, it still cannot effectively guide the airflow, resulting in significant loss of wind and atomization. This design also cannot significantly improve the atomization efficiency and atomization effect.

[0054] In order to solve the technical problem of low atomization efficiency and atomization effect in the prior art, the present application provides an atomization device and a tower fan, which can generate a cyclone inside the atomization chamber, improve the wind power, and thus improve the atomization efficiency and atomization effect.

[0055] Referring to Figures 1-13 The atomization device 10 provided by the present application comprises a box 100, an atomizer 200, and a fan 300.

[0056] The box 100 is provided with an atomization chamber 110, an air chamber 120, an air guide duct 130, an atomization hole 210, and an air inlet hole 220. The atomization hole 210 is located at the top of the box 100, and the atomization hole 210 is connected to the atomization chamber 110. The air inlet hole is connected to the air chamber 120. The atomization chamber 110 and the air chamber 120 extend along the height direction of the box 100. The air guide duct 130 is located between the atomization chamber 110 and the air chamber 120 and is connected to the atomization chamber 110 and the air chamber 120. The air guide duct 130 is arranged in an arc shape from the air chamber 120 to the atomization chamber 110.

[0057] The atomizer 200 is located in the atomization chamber 110 and is used to atomize the water mist in the atomization chamber 110 into water mist.

[0058] The fan 300 is arranged in the box 100 and is used to drive air to flow from the air inlet hole to the air chamber 120.

[0059] The atomization chamber 110 and the air chamber 120 are arranged in the length direction or the width direction of the shell

[0060] Thus, the wind is sucked into the fan 300, blows into the air cavity 120, and enters the atomization cavity 110 from the air cavity 120 to form a spiral upward cyclone in the atomization cavity 110 to blow out the mist generated by the atomizer 200. Through the design of the arc-shaped air guide wind channel 130, the airflow can smoothly enter the atomization cavity 110 along the predetermined path to form a stable cyclone airflow, avoid the turbulence and loss of the airflow, and thus can improve the airflow speed in the atomization cavity 110, enhance the atomization effect, and improve the atomization efficiency.

[0061] In some embodiments, the box body 100 includes a main body 102 and an arc-shaped air guide plate 140 located in the main body 102, which together enclose the atomization cavity 110, the air cavity 120, the mist outlet hole 210, and the air inlet hole 220.

[0062] In some embodiments, referring to Figures 1-12 , the main body 102 includes a box body 1021 and a box cover 1022 sleeved on the box body 1021.

[0063] The box cover 1022 is provided with the atomization cavity 110, the air cavity 120, and the air guide wind channel 130, and the large cavity formed between the box body 1021 and the box cover 1022 can constitute the air cavity 120.

[0064] In some embodiments, the arc-shaped air guide plate 140 has an inner arc surface 141 and an outer arc surface 142 arranged oppositely, the inner arc surface 141 and the inner wall surface of the box body 100 together enclose the atomization cavity 110, the outer arc surface 142 and the box body 100 together enclose the air cavity 120, the arc-shaped air guide plate 140 includes a first end 143 and a second end 144 connected to each other, the first end 143 is connected to the inner wall surface of the box body 100, and the outer arc surface 142 of the second end 144 is spaced from the inner wall surface of the box body 100 to form the air guide wind channel 130.

[0065] Thus, by arranging the arc-shaped air guide plate 140, when the wind is sucked into the fan 300 and blows into the air cavity 120, the wind generated by the air cavity 120 can enter the air inlet hole of the atomization cavity 110 under the action of the arc-shaped air guide plate 140, and then form a spiral upward cyclone in the atomization cavity 110 to blow out the mist generated by the atomizer 200.

[0066] In addition, the arc-shaped air guide plate 140 can isolate various turbulent flows generated when the fan 300 directly blows into the air cavity 120, and form regular cyclones in the atomization cavity 110, thereby reducing the loss of the mist, improving the atomization efficiency, and increasing the humidification amount.

[0067] In some embodiments, the arc-shaped air deflector 140 and the main body 102 are integrally formed.

[0068] In this way, the arc-shaped air deflector 140 and the main body 102 are integrally formed, which can eliminate the gap at the connection point, ensure good sealing performance, avoid air leakage, and thus enable the airflow to smoothly enter the atomization cavity 110 along the predetermined path, thereby improving the atomization efficiency.

[0069] In some embodiments, the fan 300 can be located outside the box body 1021 and arranged at the top of the box body 1021.

[0070] In addition, the embodiment of the present application also provides a tower fan 01, which comprises a shell 20, an atomization device 10, an out-mist pipe 30, and a wind wheel 40.

[0071] The shell 20 is provided with a containing space 21, a tower fan air inlet hole 22, and a tower fan air outlet 23, and the tower fan air inlet hole 22 and the tower fan air outlet 23 are communicated with the containing space 21.

[0072] The atomization device 10 is installed in the containing space 21. The atomization device 10 is the atomization device 10 mentioned in the above embodiment.

[0073] The out-mist pipe 30 is installed in the containing space 21, and the out-mist pipe 30 is communicated with the atomization cavity 110. The out-mist pipe 30 has an out-mist opening 31.

[0074] The wind wheel 40 is installed in the containing space 21 and is used to drive air to flow from the tower fan air inlet hole 22 to the tower fan air outlet 23.

[0075] In some embodiments, the box body 100 comprises a cover body 101, a main body 102, and a sealing ring 103. The cover body 101 is detachably connected to the top of the main body 102. The arc-shaped air deflector 140 and the main body 102 form the atomization cavity 110, the air cavity 120, the out-mist hole 210, and the air inlet hole 220. When the cover body 101 is connected to the main body 102, the sealing ring 103 is arranged around the air inlet hole 220 and the out-mist hole 210 and abuts between the cover body 101 and the main body 102.

[0076] In this way, by arranging the sealing ring 103 between the cover body 101 and the main body 102, the gap between the cover body 101 and the main body 102 can be sealed.

[0077] In some embodiments, the cover 101 comprises a cover body 103 and a pressing piece 104, the pressing piece 104 is movably connected to the cover body 103, when the cover 101 is connected to the main body 102, the sealing ring 103 is located on the side of the pressing piece 104 facing the main body 102, and the sealing ring 103 abuts between the pressing piece 104 and the main body 102.

[0078] In this way, by arranging the sealing ring 103 between the pressing piece 104 and the main body 102, the gap between the pressing piece 104 and the main body 102 can be sealed.

[0079] In some embodiments, the pressing piece 104 is provided with a limiting groove 105, and the sealing ring 103 is embedded in the limiting groove 105.

[0080] In some embodiments, the cover 101 further comprises an elastic piece 106, and the elastic piece 106 abuts between the cover body 103 and the pressing piece 104.

[0081] In this way, by arranging the elastic piece 106 between the cover body 103 and the pressing piece 104, the pressing piece 104 is elastically pressed against the main body 102.

[0082] In some embodiments, the side of the pressing piece 104 facing the cover body 103 is provided with a positioning column 107, one end of the positioning column 107 is connected to the pressing piece 104, the other end of the positioning column 107 is movably arranged in the cover body 103 and connected to the cover body 103, the elastic piece 106 is a spring, the elastic piece 106 is sleeved on the outer periphery of the positioning column 107 and abuts between the cover body 103 and the pressing piece 104.
