Description

Technical Field

[0001] This utility model relates to the field of atomizing fan technology, specifically to an atomizing fan rotating device. Background Technology

[0002] As an innovative electrical appliance that combines cooling and humidification functions, the atomizing fan has received widespread attention in the market in recent years. It uses an atomizing device to convert water into tiny water mist particles, and then uses the airflow generated by the fan to blow these water mists into the surrounding environment. This design can not only effectively reduce the air temperature and bring a cool and comfortable feeling to users, but also increase the air humidity and alleviate the discomfort caused by dry environments. It is especially suitable for various places such as homes, offices, shopping malls, and factories, and plays an important role in improving the quality of indoor environments. In atomizing fan usage scenarios, users often need to adjust the fan's rotation angle according to the actual environment and their own needs to change the airflow direction, allowing the cool water mist to evenly cover the desired area and improve user comfort. However, existing traditional atomizing fans have obvious design flaws. When users try to adjust the fan's rotation angle, the water tank at the bottom, which stores water for atomization, will inevitably rotate along with the fan. Since the water tank contains a certain amount of water, the inertia of the water in the tank during rotation will make the rotation of the tank unstable, causing it to shake or even tilt. The stress at the connection between the water tank and the fan body is relatively large, making the operation of adjusting the fan angle difficult and clumsy. Users need to spend more effort and energy to control the rotation of the fan and the water tank, reducing the convenience and smoothness of operation. Utility Model Content

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides an atomizing fan rotating device, which can effectively solve the technical problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an atomizing fan rotating device, including a water tank assembly, a water pump, an atomizing assembly, a fan mounting assembly, and a fan assembly.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1-5 As shown, this utility model provides an atomizing fan rotating device, including a water tank assembly, a water pump 19, an atomizing assembly, a fan mounting assembly, and a fan assembly. The water tank assembly includes an outer casing 5 and a fixing seat 16. The bottom of the outer casing 5 is closed and the top has an opening. The fixing seat 16 is mounted on the top of the outer casing 5. At least one sealing ring 20 is provided at the position where the edge of the fixing seat 16 contacts the outer casing 5 to prevent liquid in the outer casing 5 from leaking from the connection. The fixing seat 16 is provided with a connecting pipe 14. The connecting pipe 14 is hollow inside to form a water flow channel 29. One end of the connecting pipe 14 extends into the interior of the outer casing 5 and is provided with filter cotton 15. The other end is provided with a water outlet 18. The water inlet of the water pump 19 is connected to the connecting pipe 14, and the water outlet 18 of the water pump 19 is connected to the atomizing assembly. In the initial state, the outer casing 5 is sealed with a preset amount of water. The connecting pipe 14 and the filter cotton 15 extend into the water surface. The water pump 19 is started. Under the action of the water pump 19, the water flows through the pores of the filter cotton 15 towards the water flow channel 29. At this time, the filter cotton 15 filters the water flow. The filtered water flows upward along the water flow channel 29 and is discharged through the outlet 18. The atomizing component atomizes the discharged water into tiny water droplets. The air outlet of the fan component is aimed at the atomizing area of ​​the atomizing component and blows the atomized water vapor to the surrounding environment. The fan mounting assembly includes a rotating base 4, which is hollow to form a mounting cavity. Inside the mounting cavity are a battery module 10, a drive module 11, and a water pump 19, all fixedly connected to the rotating base 4. A connector 24 is fixedly connected to the water pump 19 via bolts. The drive module 11 is connected to a drive wheel 12 located on the outside of the rotating base 4, and the rotating base 4 has a driven wheel rotatably connected to it. An internal gear ring 13 is mounted on the end face of the fixed base 16. The bottom end of the rotating base 4 is fitted onto the outside of the internal gear ring 13 but not fixedly connected to it. There is a gap between the rotating base 4 and the outer casing 5 to form a rotational clearance. Both the drive wheel 12 and the driven wheel are meshed with the internal gear ring 13. The drive module 11 drives... The drive wheel 12 rotates and meshes with the gear cam. Since the internal gear ring 13 is fixed, the circumferential force applied by the drive wheel 12 to the internal gear ring 13 is fed back in the opposite direction by the internal gear ring 13, forming a reaction force that drives the rotating seat 4 to rotate. This reaction force is transmitted to the driven wheel through the rotating seat 4. While the driven wheel rotates around the connecting shaft, it converts the linear reaction force into the circumferential motion of the rotating seat 4 around the axis of the internal gear ring 13 through continuous meshing with the internal gear ring 13. This allows the rotating seat 4 to rotate 360° relative to the fixed seat 16. The battery module 10, drive module 11, water pump 19 and connector 24 rotate synchronously with the rotating seat 4, and the connecting end 25 rotates relative to the seal 26.

[0015] This embodiment also includes a pipe connection assembly, which includes a seal 26, a connector 24, a first water flow pipe 27, and a second water flow pipe 21. The seal 26 has a T-shaped cross-section. During assembly, the lower end of the seal 26 is embedded inside the outlet 18, and the outer wall of the seal 26 is tightly fitted with the inner wall of the outlet 18. The bottom of the connector 24 has a protrusion 28 and a connecting end 25 formed sequentially from the inside to the outside. The protrusion 28 presses the seal 26 tightly, and the connecting end 25 is inserted into the seal 26 and press-fitted with it. This design can effectively prevent water leakage and ensure sealing reliability. The connecting end 25 is hollow to form a water inlet channel. One end of the first water flow pipe 27 is mounted on the connector 24 and communicates with the water inlet channel. The other end is connected to the water inlet of the water pump 19. One end of the second water flow pipe 21 is connected to the water outlet 18 of the water pump 19. The other end is connected to the atomizing nozzle 1. The water pump 19 provides power for the water flow, sucks the water flow from the water flow channel 29, pressurizes it, and discharges it from the water outlet 18. The atomizing nozzle 1 atomizes the pressurized water flow into fine water droplets to achieve the atomization function.

[0016] The fan mounting assembly in this embodiment also includes a mounting bracket 2 integrally formed with the rotating base 4. The upper end of the mounting bracket 2 is horizontally U-shaped, with the opening facing the fan assembly. The mounting bracket 2 is provided with two symmetrically distributed rotating shaft protrusions 6, and each rotating shaft protrusion 6 is provided with an angle limiting protrusion 7 on its outer periphery. The fan assembly includes a base frame 32, a front frame 33, a drive motor 30, and fan blades 22. The drive motor 30 is fixed to the base frame 32 with screws and is connected to the fan blades 22 for driving. The front frame 33 is fastened to the base frame 32 through a snap-fit ​​structure. The base frame 32 is provided with a shaft hole 31 that mates with the shaft protrusion 6. The inner wall of the shaft hole 31 is provided with an abutment protrusion. The shaft protrusion 6 is inserted into the shaft hole 31 to form a clearance fit. When the base frame 32 rotates relative to the mounting bracket 2 to the maximum angle, the angle limiting protrusion 7 contacts the abutment protrusion to limit the rotation range.

[0017] In this embodiment, a control circuit board 34 and a plurality of LED beads 36 are provided on the outer edge of the front frame 33. The control circuit board 34 is connected to the plurality of LED beads 36 for controlling the brightness, color and flashing frequency of the LED beads according to a preset program or external control signal. In addition, the front frame 33 is equipped with a light-transmitting plate 35, which covers the area where the control circuit board 34 and LED beads are located, and is used to protect the control circuit board 34 and LED beads, while ensuring that the light from the LED beads can pass through normally. The front frame 33 is provided with a hole for the atomizing nozzle 1 to pass through.

[0018] In this embodiment, the fixed base 16 is provided with a water inlet 17, and the rotating base 4 is provided with a flip cover 3 rotatably connected to it. A sealing plug 23 is installed on the side of the flip cover 3 facing the water inlet 17. When water needs to be injected, the user rotates the flip cover 3, so that the flip cover 3 rotates around the rotatable connection with the rotating base 4. When the flip cover 3 is rotated to the appropriate position, the water inlet 17 is fully exposed. At this time, the user can inject water into the water inlet 17 of the fixed base 16. After the water is injected, the user rotates the flip cover 3 again, so that it rotates in the opposite direction until the sealing plug 23 on the side of the flip cover 3 facing the water inlet 17 is tightly inserted into the water inlet 17, thereby sealing the water inlet 17 and preventing internal liquid leakage or external impurities from entering.

[0019] In this embodiment, the mounting bracket 2 is equipped with a main control circuit board, a charging interface, an indicator light 8, and multiple function buttons 9. The charging interface, function buttons 9, and indicator light 8 are electrically connected to the main control circuit board. The charging interface is located on one side of the mounting bracket 2, the indicator light 8 is located on the front of the mounting bracket 2, and multiple function buttons 9 are arranged in a matrix below the indicator light 8. The outer edge of the function buttons 9 is fitted with a sealing ring 20 to prevent external moisture from entering the interior of the mounting bracket 2 and affecting the electrical connection.

[0020] Compared to traditional technologies: The rotating base 4 is rotatably connected to the fixed base 16, and the rotating base 4 can rotate 360° relative to the fixed base 16. Since the outer casing 5 and the fixed base 16 are fixed and do not participate in the rotation, on the one hand, the stress on the connection between the water tank and the fan assembly is reduced. On the other hand, the rotating base 4 can rotate 360° relative to the fixed base 16, which allows for flexible adjustment of the air delivery direction of the fan assembly. The fixed water tank does not affect the flexibility of rotation, and users can precisely control the air delivery angle according to actual needs.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
