Description

Technical Field

[0001] This utility model relates to the field of fan-related technology, and in particular to a fan structure that can spray mist. Background Technology

[0002] Fans are common household appliances in our daily lives, used to cool off in hot weather. Due to their practical function, fans are widely used.

[0003] Most ordinary fans only have a single function of blowing air and cooling. When used in dry seasons or air-conditioned environments, they cannot improve air humidity. Long-term use can easily lead to problems such as dry skin and respiratory discomfort, failing to meet users' comprehensive needs for a comfortable air environment. To solve this problem, some users will use a humidifier separately. However, humidifiers and fans are independent devices, which not only take up a lot of space and are inconvenient to move and store, but also have the disadvantages of high operating costs and cumbersome operation. Moreover, when the two are used together, the water vapor diffusion is uneven, and the humidification effect is limited.

[0004] In summary, there is a need for a sprayable fan structure with environmental humidification function. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art by providing a sprayable fan structure with environmental humidification function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A sprayable fan structure, comprising: The base includes a fan ring housing, a water storage box is fixed inside the fan ring housing, and the water storage box has an opening on the front side. A front cover is installed and fixed at the front port of the fan ring housing. A water storage box cover that matches the opening of the water storage box is fixed on the front cover. The water storage box cover and the opening of the water storage box are sealed together. An atomizing plate is fixed on the water storage box cover. The rear cover is installed and fixed at the rear port of the fan ring housing. A motor is installed and fixed on the rear cover, and a fan blade assembly is installed and fixed on the motor shaft. The fan blade assembly is located behind the water storage box.

[0007] In use, water can be poured into the water tank. After starting the fan, the motor drives the fan blade assembly to rotate, generating airflow. At the same time, the atomizing plate is energized to atomize the water in the water tank. The atomized water vapor is blown forward by the airflow generated by the fan blade assembly, achieving simultaneous operation of air blowing and atomization humidification. The compact and reasonable structural design combines the dual functions of air blowing and cooling with environmental humidification, meeting the needs of regulating ambient temperature and improving air humidity, thus enhancing functionality.

[0008] Preferably, the fan ring housing has an internal water tank located above the water storage box. The water tank and the water storage box are connected by three drainage channels located on both sides and the top of the water storage box. The top of the fan ring housing has a water inlet connected to the water tank, and this inlet has a flip-top cover. Clean water is injected into the water tank through the inlet on the top of the fan ring housing. The clean water flows smoothly into the water storage box through the three drainage channels on both sides and the top. When the fan is started, the motor drives the fan blade assembly to generate airflow. Simultaneously, the atomizing plate atomizes the water in the water storage box, and the water vapor is blown forward with the airflow, achieving simultaneous operation of air blowing and humidification. The three drainage channels increase the water storage capacity and ensure a uniform and stable water supply. The flip-top design of the water inlet facilitates water filling and prevents dust and leakage.

[0009] Preferably, a water level viewing window is provided on the side wall of the fan ring housing, and the water level viewing window is located on the side of the water tank. The water level viewing window on the side wall of the fan ring housing allows for direct observation of the remaining water level in the water tank, facilitating timely water replenishment and preventing leakage due to overfilling, further improving ease of use and safety.

[0010] Preferably, the side of the water tank cover facing away from the water tank has an atomizing plate mounting groove. The atomizing plate includes an outer base ring placed in the atomizing plate mounting groove. A working inner core is fixed inside the outer base ring. A water passage hole matching the working inner core is provided on the bottom surface of the atomizing plate mounting groove. One side of the outer base ring is sealed to the bottom surface of the atomizing plate mounting groove. A decorative cover is installed and fixed on the front cover. The decorative cover is located on the front side of the water tank cover. The atomizing plate is fixed between the decorative cover and the water tank cover. The other side of the outer base ring is sealed to the decorative cover. The decorative cover has a spray hole matching the working inner core. A spray hole flip cover is provided at the spray hole. A groove for mounting the atomizing plate and a water passage hole are machined on the side of the water tank cover facing away from the water tank. One side of the outer base ring is placed on the bottom of the mounting groove, and the gap between the outer base ring and the mounting groove is sealed with a sealing ring or gasket. A decorative cover with a spray hole flap is then installed and fixed to the front hood, positioned in front of the water tank cover, clamping the atomizing plate between the decorative cover and the water tank cover, and sealing the gap between the outer base ring and the decorative cover again with a sealing ring or gasket. During spraying, water from the water tank contacts the working core of the atomizing plate through the water passage hole. When the atomizing plate is energized, it atomizes the water. The atomized water vapor is blown out through the spray hole on the decorative cover by the airflow generated by the fan blade assembly. When not in use, the spray hole flap is closed to block the spray hole. The atomizing plate is fixed by a double-sealed structure, and the precise fit between the water passage hole and the spray hole ensures both a leak-proof seal and effective atomization, further enhancing the product's reliability.

[0011] Preferably, the device also includes a base with a socket on its top and a plug fixed to the bottom of the rear cover. The plug and the socket are interlocked. A button groove is provided on the side wall of the plug. A release button is movably connected to the inside of the button groove. A spring is provided at the bottom of the button groove. One end of the release button is connected to the bottom of the button groove by the spring. A button limiting block is fixed at the edge of the button groove opening. Under the elastic force of the spring, the release button is pushed against the button limiting block at the opening of the button groove, and the other end of the release button is located outside the button groove. A button locking hole matching the other end of the release button is provided on the side wall of the socket. An insertion transition inclined guide surface is provided on the other end of the release button and the side closest to the bottom of the socket. An insertion port is provided on the top of the base, and a button locking hole is provided on the side wall. A plug with a button slot is fixed at the bottom of the rear cover. A spring and a release button are installed in the button slot. A button limiting block is provided at the slot so that the release button is partially exposed under the action of the spring, and the end has a plug-in transition inclined guide surface. When the plug is inserted into the insertion port, the release button moves towards the bottom of the button slot under the guidance of the plug-in transition inclined guide surface and is compressed by the spring. After being fully inserted, the release button is locked into the button locking hole under the action of the spring force and is fixed. Pressing the release button can unlock and separate the fan body. This can achieve quick assembly and disassembly between the fan body and the base. The connection is stable and the operation is convenient. At the same time, it improves the product assembly flexibility and ease of use.

[0012] Preferably, the rear cover is provided with a handle groove, which is located on the top and rear side of the rear cover. The groove wall is inclined at 10° to 15° relative to the central axis of the fan ring housing, and the height of the opening of the handle groove is lower than the height of the bottom of the groove. The handle groove on the top rear side of the rear cover is designed with a 10° to 15° inclination and the opening is lower than the bottom of the groove, which conforms to ergonomics and facilitates gripping and carrying.

[0013] Preferably, a power supply is installed and fixed on the rear cover, and the motor and atomizing plate are electrically connected to the power supply.
