The air supply device generates airflow, which is blown into the water mist collection hood through the air outlet duct. The water mist in the air is blown to the spray plate through the connecting pipe and sent out by the fan blade assembly.

[0008] This utility model significantly improves the integration of the structure by integrating the water collection tray and the base into one piece, reducing the number of parts and assembly steps, and lowering production costs and assembly complexity. The coordinated work of the water mist collection cover, atomizing device, and air outlet ensures the efficient generation and delivery of water mist. The overall structure is compact and highly integrated, making it suitable for various scenarios such as home and office, and has good practicality and market competitiveness.

[0009] In some embodiments, after the connecting pipe is connected to the water mist collection hood, it passes through the riser and the inside of the housing in sequence before connecting to the spray disc.

[0010] This embodiment effectively avoids the impact of exposed pipes on the overall aesthetics of the product through an internally integrated piping design.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0037] This utility model provides a spray fan, comprising: a base 1 and a vertical pipe 2 fixedly connected to the base 1. A housing 3 is connected to the upper end of the vertical pipe 2. A control device 4 is installed inside the housing 3. A fan blade assembly 5, electrically connected to the control device 4, is rotatably mounted on the upper end of the housing 3 via a pivot. A spray disc 6 with a spray groove 602 is fixedly mounted on the front of the fan blade assembly 5. Specifically, an integrally formed water receiving tray 101 is recessed on the upper surface of the base 1. The lower end of a water tank 7 matches the shape of the water receiving tray 101 and can be inserted into the water receiving tray 101 to achieve a water filling function. A water mist collecting hood 8 is provided in the water receiving tray 101. The lower end of the water mist collecting hood 8 forms a water inlet gap communicating with the water receiving tray 101 and is connected to the spray disc 6 via a connecting pipe 9. Furthermore, an atomizing device 10 is installed on the water receiving tray 101 within the water mist collection hood 8 to atomize the water. An air supply device is also provided inside the base 1, and an air outlet 102 is erected on the water receiving tray 101. One end of the air outlet 102 is connected to the air supply device, and the other end extends into the water mist collection hood 8 to form an air outlet 1021. In this way, the airflow generated by the air supply device is blown into the water mist collection hood 8 through the air outlet 102, and the water mist is blown towards the spray disc 6 via the connecting pipe 9, and finally delivered by the fan blade assembly 5.

[0038] Specifically, the air duct 102 can also be integrally injection molded with the water receiving tray 101, and the base 1 has an air inlet at the bottom.

[0039] Specifically, the fan blade assembly 5 includes a drive assembly consisting of a motor and fan blades.

[0040] Specifically, the air supply device is located inside the base 1 and is a fan used to provide power airflow for the atomization system.

[0041] Centrifugal fans or small axial fans can be used. Centrifugal fans are preferred because they have high air pressure and the airflow direction is perpendicular to the rotation axis (which is very suitable for blowing air from bottom to top). Air can be blown in from the connection point with the air outlet 102 and discharged at high pressure from the air outlet 1021 of the air outlet 102. The air supply device and the control device 4 are connected by wires to the control device 4 and electrically connected to it.

[0042] Specifically, the atomizing device 10 can be a piezoelectric ultrasonic atomizer. A hole is made on the water receiving tray 101 corresponding to the position of the atomizing device 10, allowing the connecting wire to pass through the base 1 and then be led to the control device 4 for electrical connection. The edges of the hole are sealed.

[0043] Specifically, the control device 4 includes: control buttons located on the surface of the housing 3 and a control circuit board located inside the housing 3 and electrically connected to the control buttons.

[0044] Furthermore, after the connecting pipe 9 is connected to the water mist collection hood 8, it passes through the inside of the riser 2 and the outer casing 3 in sequence, and finally connects to the spray disc 6. This arrangement allows all the pipes to be built-in, which is not only aesthetically pleasing but also avoids damage from external impacts. Flexible plastic pipes are preferred, as they have a certain degree of bending performance, which facilitates pipe laying, and the pipe diameter can be selected to be approximately 8 mm to balance water mist delivery efficiency and space occupation.

[0045] In some embodiments, the lower end of the water tank 7 is provided with a water outlet 701, and a first mounting cavity 103 extends upward in the water receiving tray 101 for the water outlet 701 to be inserted into. A core 11 is vertically arranged in the first mounting cavity 103. When the water tank 7 is installed, the core 11 is inserted into the water outlet 701 and pushes it open, thereby realizing automatic water dispensing. A notch 1031 is provided on the side of the first mounting cavity 103 to allow water to flow smoothly into the water receiving tray 101. Preferably, the core 11 is made of rubber to ensure sealing, and the width of the notch 1031 can be about 10 mm to ensure smooth water flow.

[0046] When the core 11 is not precisely aligned with the outlet 701 of the water tank 7, or when the core 11 deforms due to prolonged use, a large amount of water may overflow from the water tank 7. To address this, it is preferable to extend upwards in the water receiving tray 101 to form a second mounting cavity 104 with a height lower than the depth of the water receiving tray 101, and install a water level detection device 12 therein. When the water level is too high and overflows into the second mounting cavity 104, this device can trigger an audible and visual alarm to promptly alert the user. The preferred water level detection device 12 includes a float switch or a photoelectric sensor, which is connected to the control device 4 via wires to achieve automatic water level monitoring and alarm functions.

[0047] Specifically, the connecting pipe 9 is installed on top of the water mist collection hood 8. In particular, the air outlet 1021 of the air outlet 102 adopts an arc-shaped structure, its orientation opposite to that of the atomizing device 10. The water mist collection hood 8 has a corresponding arc-shaped guide section 801 that matches its shape. When the air supply device is activated, the airflow is guided through the arc-shaped air outlet 1021 and then sent out in an arc shape. It is then guided a second time by the arc-shaped guide section 801 of the water mist collection hood 8, further enhancing its arc-shaped flow. This allows the water mist around the atomizing device 10 to be more smoothly carried upwards into the connecting pipe 9 in an arc-shaped motion. This design not only effectively improves the water mist delivery efficiency but also helps reduce energy loss, further enhancing the spraying effect.

[0048] Furthermore, the water tray 101 is provided with multiple screw sleeves 105 corresponding to the positions of the water mist collection cover 8, and the water mist collection cover 8 is locked and fixed by screws 13. Preferably, the screw sleeves 105 and the water tray 101 are integrally injection molded, and the screws 13 can be self-tapping screws 13 to achieve quick assembly. This method not only provides a firm connection, but also facilitates disassembly for cleaning or replacement of parts.

[0049] Preferably, the two sides of the water tank 7 are symmetrically recessed near the top to form two handle grooves 702, and the area on the top of the water tank 7 corresponding to the handle grooves 702 is also provided with anti-slip texture 703. The depth and width of the handle grooves 702 are suitable for adult fingers to grip, and the anti-slip texture 703 can be designed as dots or stripes to increase friction. In this way, the portability and operational safety of the water tank 7 are significantly improved.

[0050] Specifically, the spray disc 6 has multiple air inlets 601 on one side of the base 1 for the fan blade assembly 5 to blow air in, and a spray groove 602 is evenly opened on the front side to achieve uniform spraying of water mist.

[0051] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
