Description

Technical Field

[0001] This application relates to the field of handheld fans, specifically to the field of a handheld spray fan technology. Background Technology

[0002] Handheld fans, as portable cooling tools, are gradually becoming popular products on the market. At the same time, handheld mist fans with humidification functions have appeared on the market. These handheld mist fans integrate a miniature water pump and water tank into the fan structure, evenly atomizing water and delivering it with the wind, thus achieving the dual effects of cooling and humidification.

[0003] Conventional designs typically integrate the water tank and handle, using a screw-on assembly method, similar to the structure of a traditional spray bottle. However, because spray fans require frequent refilling, the water tank needs to be disassembled and reassembled frequently. The screw-on design can easily lead to decreased sealing performance, resulting in leaks. Secondly, this design makes assembling the fan head more difficult, increasing the complexity and cost of the production process.

[0004] Therefore, there is still considerable room for improvement in the structural design of existing handheld spray fans, especially in terms of improving the water tank's sealing performance, simplifying the disassembly and assembly process, and improving overall assembly efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art as described above, this application proposes a handheld spray fan that improves at least one of the problems mentioned above by optimizing the installation structure of the water tank.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] This application discloses a handheld spray fan, including a water bottle and a fan assembly connected to the upper end of the water bottle. The lower end of the water bottle is provided with a cover, and the water bottle serves as the handle of the fan assembly.

[0008] The fan assembly includes a front shell and a rear shell, and fan blades. The front shell and the rear shell are fitted together and form a hollow vent at their upper end and a mounting cylinder at their lower end. The fan blades are disposed in the vent, and the kettle is installed inside the mounting cylinder.

[0009] It also includes a pump body for drawing water from a kettle and a control handle for triggering the operation of the pump body. The pump body is located at the upper end of the kettle and installed inside the mounting cylinder. The upper end of the pump body is provided with a nozzle, and the lower end is provided with a water suction pipe. The nozzle is located inside the vent.

[0010] The fan assembly is framed by a single front and rear housing. A vent for mounting the fan blades is formed at the upper end of this frame, while a mounting sleeve for the water tank is formed at the lower end. This allows for the assembly of the entire fan assembly and water tank simply by fitting the front and rear housings together, significantly improving assembly efficiency.

[0011] Meanwhile, the lid is located at the bottom of the kettle, which serves as the handle, allowing for a larger diameter lid with good operability. Compared to removing the neck from the top of the kettle, it offers better durability.

[0012] In some possible implementations, a fan blade holder for mounting the fan blades is provided extending upward from the middle of the front and rear housings.

[0013] In some possible implementations, the nozzle is fixed to the blade seat and located at the lower end of the blade.

[0014] In some possible implementations, the front and rear housings are respectively provided with power batteries at the left and right ends of the pump body.

[0015] In some possible implementations, the kettle is connected to the mounting cylinder via a flange seal.

[0016] In some possible implementations, the flange seal is disposed between the pump body and the kettle.

[0017] In some possible implementations, the flange sealing ring includes a flange ring, an upper sleeve disposed at the upper end of the flange ring and fitted into the pump body, and a lower sleeve disposed at the lower end of the flange ring and fitted into the kettle.

[0018] In some possible implementations, the upper end of the kettle is provided with a concave mounting groove, and the mounting cylinder is provided with a threaded post that can be inserted into the mounting groove.

[0019] In some possible implementations, the outer wall of the kettle is a gradually expanding slope from top to bottom, and the slope is provided with a plurality of recessed concave rings. Attached Figure Description

[0026] The following examples further illustrate the features of this application and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0029] Please refer to Figures 1 to 4 The handheld spray fan of this application includes a water bottle 1 that can be refilled with water and a fan assembly 2 connected to the upper end of the water bottle 1. The water in the water bottle 1 is pumped to the fan assembly 2 and atomized when the fan blows. The water mist, together with the fan, helps to disperse the air and accelerate the cooling effect.

[0030] First, the kettle 1 is made of transparent material, which can be polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), etc. There are no restrictions on the material. The main purpose is to make the transparent material reflect the visual design and make it easy for users to observe the water level.

[0031] Meanwhile, the water bottle 1 can also be used as a handle for the fan assembly 2. A cover 11 is located at its lower end, and the cover 11 is sealed by a sealing gasket 12 and threadedly connected to the water bottle 1. To improve grip, the outer wall of the water bottle 1 has a gradually widening slope from top to bottom, and multiple recessed rings 13 are provided on the slope. At this point, the diameter at its lower end is relatively large, making the removal and installation of the cover 11 more operable and stable compared to removing it from the neck of the water bottle 1, thus exhibiting better durability.

[0032] The fan assembly 2 includes a front housing 21 and a rear housing 22, and fan blades 23. The front housing 21 and the rear housing 22 are attached to each other and form a hollow vent 24 at their upper ends, and a mounting cylinder 25 at their lower ends. At this time, the fan blades 23 are placed in the vent 24, and the water bottle 1 is installed in the mounting cylinder 25. The front housing 21 and the rear housing 22 can be fastened by bolts. This method only requires alignment and tightening the bolts at the rear housing 22. It is a conventional fastening method and will not be described in detail.

[0033] A fan blade holder 241 for mounting the fan blade 23 extends upward from the middle of the front shell 21 and the rear shell 22, and is located in the middle of the vent 24. At this time, the vent 24 is open. The fan blade 23 is made of toy-grade softness to avoid scratching hands. Specifically, it can be made of soft materials such as silicone, thermoplastic elastomer (TPE), or polyurethane (PU), without specific limitations. A motor 231 and a motor mount 232 can be installed at the rear end of the fan blade 23. The control button 233 for the motor 231 can also be located on the motor mount 232, which is installed on the rear shell 22 for easy maintenance.

[0034] Water is drawn from the kettle 1 via the pump body 3 and the control handle 4 that activates the pump body 3. The pump body 3 is located at the top of the kettle 1 and is installed inside the mounting cylinder 25. The pump body 3 is positioned at the top of the kettle 1 within the mounting cylinder 25; that is, the kettle 1 is fixed at the bottom of the mounting cylinder 25, and the pump body 3 is fixed at the top, thus achieving a sealed installation of the kettle 1. In the field of spray bottles, using the pump body 3 to achieve spraying is a common industry technique, and will not be elaborated upon or limited further. For example, a piston pump can be used, with the control handle 4 triggering the piston and a spring return mechanism. In this case, the piston moves as the control handle 4 is pressed, and the cylinder serves as the fixing component of the pump body 3 as described above.

[0035] Furthermore, the pump body 3 has a nozzle 31 at its upper end and a water suction pipe 32 at its lower end, with the nozzle 31 disposed inside the ventilation opening 24. Specifically, the nozzle 31 is fixed to the fan blade seat 241 and is located at the lower end of the fan blade 23.

[0036] At this time, as the power supply device for the motor 231, power batteries 234 are respectively installed at the left and right ends of the pump body 3 on the front shell 21 and the rear shell 22. Two AA batteries can be used. In this way, the installation space of the power supply can be saved, and the maintenance plate 221 is set at the lower end of the rear shell 22 to facilitate the replacement of the power batteries 234. To prevent them from falling, they are fastened with half-threaded screws.

[0037] Thus, the fan assembly 2 is formed by the integrated front shell 21 and rear shell 22, with a vent 24 for mounting the fan blades 23 at the upper end of the frame and a mounting cylinder 25 for mounting the water tank 1 at the lower end. This allows for the installation of the entire fan assembly 2 and water tank 1 simply by fitting the front shell 21 and rear shell 23 together, significantly improving assembly efficiency.

[0038] At this point, the key is ensuring the seals are properly maintained on the water tank 1, pump body 3, and fan assembly 2. Please refer to [reference needed]. Figure 5 and Figure 6 The kettle 1 is connected to the mounting cylinder 25 via a flange sealing ring 4. Specifically, the flange sealing ring 5 is located between the pump body 3 and the kettle 1, meaning the kettle 1 is secured to the lower end of the mounting cylinder 25 while pressure is applied to the pump body 1 at the upper end. This allows the flange sealing ring 5 to achieve a sealing effect. Optionally, the mounting cylinder 25 can secure the kettle 1 by providing a concave mounting groove 14 at the upper end of the kettle 1, and by providing two threaded posts 251 within the mounting cylinder 25 that can be inserted into the mounting groove 14, thus creating a clamping and securing effect on the kettle 1.

[0039] Furthermore, the flange sealing ring 5 can be made of silicone or ethylene propylene diene monomer (EPDM) rubber, including a flange ring 51. The upper end of the flange ring 51 is provided with an upper sleeve 52 that can be fitted into the pump body 3, and the lower end of the flange ring 51 is provided with a lower sleeve 53 that can be fitted into the water tank 1. Through the double sleeve sealing, a more stable sealing effect can be achieved.

[0040] As stated above, this case protects a handheld spray fan, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
