Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a portable atomizing spray fan. Background Technology

[0002] In the hot summer, fans have become an indispensable cooling tool in people's lives. However, in some areas or environments, the cooling effect of fans is greatly reduced due to the excessively hot summer air, and it is easy to make people feel dry. Ordinary electric fans can no longer meet the requirements for cooling off. Therefore, misting fans and atomizing fans have appeared on the market. They can be connected to an external liquid source to add water mist when the fan is working, which improves the cooling effect and has a good moisturizing effect. They are widely used in various places to provide people with a more comfortable environment.

[0003] Most current misting fans have a water tank at the bottom and a spray nozzle at the air outlet, which is extremely inconvenient to move. The complex overall structure also detracts from the aesthetics of the misting fan, and its poor flexibility makes it inconvenient to use. Therefore, it is necessary to improve the existing technology to overcome these shortcomings. Summary of the Invention

[0004] To overcome the shortcomings and deficiencies of existing technologies, the purpose of this utility model is to provide a portable atomizing spray fan. This portable atomizing spray fan features a dual-purpose liquid storage container. In use, the base assembly can be installed face-up at the opening of the liquid storage container, placing the container at the bottom of the fan assembly. A pump assembly pumps the liquid from the container to the atomizing nozzle, where it is atomized and sprayed out. The mist, carried by the fan blades, is then blown onto the body for faster cooling. When not in use or for transport, the base assembly can be installed face-down at the opening of the liquid storage container, storing the fan assembly inside. This reduces storage space, facilitates transport and organization, and enhances the practicality of the spray fan.

[0005] The objective of this utility model is achieved through the following technical solution: a portable atomizing spray fan, comprising a fan assembly, a base assembly, a rotating support shaft, and a liquid storage container. The fan assembly is provided with a plurality of atomizing nozzles. The fan assembly is movably mounted on the upper end of the base assembly via the rotating support shaft.

The fan assembly can be housed inside the liquid storage container. One end of the water pump assembly extends into the liquid storage container, and the other end of the water pump assembly extends through the rotating support shaft to the atomizing nozzle and communicates with the atomizing nozzle.

[0006] Furthermore, the base assembly includes a housing and a base. The housing is mounted on the upper surface of the base. The housing has first locking holes on opposite sides. A bidirectional rotating locking pin is provided in the first locking hole. The opening end of the liquid storage container has a second locking hole corresponding to the first locking hole. When the base assembly is installed in the forward or reverse direction at the opening end of the liquid storage container, the rotating locking pin extends into the second locking hole and locks.

[0007] Furthermore, the water pump assembly includes a water pump, an inlet pipe, and an outlet pipe. The water pump is fixed inside the housing. One end of the inlet pipe is connected to the inlet of the water pump, and the other end of the inlet pipe extends through the base into the storage container. One end of the outlet pipe is connected to the outlet of the water pump, and the other end of the outlet pipe extends through the rotating support shaft to the atomizing nozzle and is connected to the atomizing nozzle.

[0008] Furthermore, the fan assembly includes a fan cover, fan blades, a first drive motor, and a liquid storage tank. The fan cover includes a front cover and a rear cover.

[0026] See Figure 1-6 A portable atomizing spray fan includes a fan assembly 1, a base assembly 2, a rotating support shaft 3, and a liquid storage container 4. The fan assembly 1 is provided with a plurality of atomizing nozzles 16. The fan assembly 1 is movably mounted on the upper end of the base assembly 2 via the rotating support shaft 3. A water pump assembly is provided inside the base assembly 2. The base assembly 2 is correspondingly disposed at the open end of the liquid storage container 4. The fan assembly 1 can be housed in the liquid storage container 4. One end of the water pump assembly extends into the liquid storage container 4, and the other end of the water pump assembly extends through the rotating support shaft 3 to the atomizing nozzle 16 and communicates with the atomizing nozzle 16.

[0027] In this embodiment, the base assembly 2 includes a housing 21 and a base 22. The housing 21 is mounted on the upper surface of the base 22. The housing 21 has first locking holes 211 on opposite sides. The first locking holes 211 have bidirectional rotating locking pins 212. The opening end of the liquid storage container 4 has a second locking hole 41 corresponding to the first locking hole 211. When the base assembly 2 is mounted in the forward or reverse direction at the opening end of the liquid storage container 4, the rotating locking pin extends into the second locking hole 41 and locks.

[0028] The portable atomizing spray fan in this embodiment, by providing a dual-purpose liquid storage container 4, allows the base assembly 2 to be installed upright at the open end of the liquid storage container 4 during use, so that the liquid storage container 4 is located at the bottom of the fan assembly 1 (see...). Figure 1As shown), the base assembly 2 and the liquid storage container 4 are locked by a bidirectional rotating locking pin 212 located in the first locking hole 211 and the second locking hole 41, which improves the stability of the assembled product. When the fan is turned on, the pump assembly pumps the liquid in the liquid storage container 4 to the atomizing nozzle 16, which atomizes the liquid and sprays it out (the amount of atomization by the atomizing nozzle 16 can be adjusted according to the actual needs by adjusting the number of atomizing nozzles 16 that are open or closed). The air blown by the fan blades 13 blows the mist onto the human body to achieve a faster cooling effect. When transporting or not in use, the base assembly 2 is installed upside down at the open end of the liquid storage container 4 so that the fan assembly 1 is stored inside the liquid storage container 4 (see...). Figure 2 As shown in the figure, the base assembly 2 and the liquid storage container 4 are locked by a bidirectional rotating locking pin 212 located in the first locking hole 211 and the second locking hole 41, which reduces the placement space and facilitates transportation or daily maintenance, thus improving the practicality of the spray fan.

[0029] In this embodiment, the water pump assembly includes a water pump 231, an inlet pipe 232, and an outlet pipe 233. The water pump 231 is fixed inside the housing 21. One end of the inlet pipe 232 is connected to the inlet of the water pump 231, and the other end of the inlet pipe 232 extends through the base 22 into the liquid storage container 4 (when the fan assembly 1 is housed in the liquid storage container 4, the inlet pipe 232 is embedded in the groove provided in the base 22). One end of the outlet pipe 233 is connected to the outlet of the water pump 231, and the other end of the outlet pipe 233 extends through the rotating support shaft 3 to the atomizing nozzle 16 and is connected to the atomizing nozzle 16.

[0030] In this embodiment, the fan assembly 1 includes a fan cover, fan blades 13, a first drive motor 14, and a liquid storage tank 15. The fan cover includes a front cover 11 and a rear cover 12. The bottom of the rear cover 12 is mounted on the base assembly 2 via a rotating support shaft 3. The fan blades 13 and the first drive motor 14 are installed inside the fan cover, and the first drive motor 14 is driven to drive the fan blades 13 to rotate. The liquid storage tank 15 is fixed inside the fan cover and located in front of the fan blades 13. Each of the atomizing nozzles 16 is evenly arranged in the liquid storage tank 15 to atomize and spray the liquid in the liquid storage tank 15. The liquid outlet pipe 233 is connected to the liquid storage tank 15. The pump assembly also includes a pressure relief pipe 234. The liquid storage tank 15 is provided with a pressure relief valve. One end of the pressure relief pipe 234 passes through the rotating support shaft 3 and is connected to the pressure relief valve. The other end of the pressure relief pipe 234 extends into the liquid storage container 4.

[0031] In this embodiment, the water pump assembly adopts the specific structure described above. When in use, the water pump 231 is started to draw the liquid in the storage container 4 from the inlet pipe 232 and pump it out from the outlet pipe 233 to the storage tank 15. (By setting a pressure relief valve, the pressure of the liquid or gas in the storage tank 15 can be effectively controlled to avoid the situation where the internal pressure is too high and damages the storage tank 15 or other related components due to the liquid or gas in the storage tank 15 not being sprayed out in time. When depressurizing, the excess liquid or gas flows out through the pressure relief valve and enters the pressure relief pipe 234. After passing through the pressure relief pipe 234, it flows back into the storage container 4 to achieve pressure relief.) After being atomized by the atomizing nozzle 16, it is sprayed out. Accompanied by the wind blown by the fan blade 13, the mist is blown onto the human body to achieve a faster cooling effect.

[0032] In this embodiment, the base assembly 2 is further provided with a second drive motor 24, a control circuit board 25 (the control circuit board 25 has built-in control programs, including but not limited to control programs for controlling the speed of the fan blade 13, the left and right swing of the fan cover, the power of the water pump 231, and the opening and closing of the atomizing nozzle 16), and a battery assembly 26. The second drive motor 24 is fixed inside the base 22, and the power output end of the second drive motor 24 is connected to the rotating support shaft 3. The second drive motor 24 can drive the rotating support shaft 3 to rotate in the forward or reverse direction, thereby driving the fan head to swing left and right. The control circuit board 25 is fixed inside the housing 21, and the control circuit board 25 extends outward to provide a button 27 for controlling the operation of the fan. The first drive motor 14, the second drive motor 24, and the battery assembly 26 are all electrically connected to the control circuit board 25.

[0033] In this embodiment, the lower end of the base 22 is provided with a rotatable handle 28, and the lower end of the base 22 is recessed with a receiving groove 221 corresponding to the handle 28. When the fan is not in use, the handle 28 can be stored in the receiving groove 221 (see...). Figure 2 As shown, when moving the fan, the handle 28 can be rotated to pull the handle 28 out of the receiving slot 221, making it easier for the user to hold the handle 28 and move the fan.

[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
