Description

Technical Field

[0001] This utility model relates to the field of atomizing fan technology, specifically to an atomizing fan 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. Most commercially available atomizing fans work by connecting a water pump to a pipe, with a filter cotton installed at the end of the pipe. Water flows through the filter cotton before entering the atomizing device, thus filtering out larger particles and impurities. However, this water flow path design has significant limitations. First, the single water flow path restricts the distribution and flow of water. When the pipe becomes blocked or malfunctions, the entire water supply system will not function properly. The lack of redundancy and emergency mechanisms reduces the reliability and stability of the equipment. Second, due to the small surface area of ​​the filter cotton, its contact area with water is also relatively small. During the process of water flowing through the filter cotton, only a portion of the water can make full contact with the filter cotton. A large amount of water passes directly without effective filtration, failing to effectively intercept tiny particles, bacteria, and impurities in the water. This not only affects the normal operation of the atomizing device and reduces the atomization quality but may also cause these impurities to be sprayed out with the water mist. In addition, the small surface area of ​​the filter cotton also makes it prone to clogging, requiring frequent replacement or cleaning, increasing the cost of use and maintenance difficulty.

The water flow channel is connected to the water inlet.

[0005] Furthermore, the bottom of the inner cover is provided with a positioning part, which is used to fix the position of the filter cotton.

[0017] 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.

[0018] like Figure 1-11 As shown, this utility model provides an atomizing fan device, including a water tank assembly, a negative pressure assembly, an atomizing assembly, and a fan assembly. The water tank assembly includes an outer box 1 and an inner cover 16. The bottom of the outer box 1 is closed and the top has an opening. Filter cotton 17 is installed inside the outer box. The top of the inner cover 16 is closed and the bottom has an opening. At least one water inlet 20 is provided on the side. The inner cover 16 is installed inside the outer box 1. There is a gap between the outer wall of the inner cover 16 and the inner wall of the outer box 1 to form a water flow channel 18. More specifically, the water flow channel 18 is an annular surface surrounding the inner cover 16. The water flow channel 18 is interconnected with the water inlet 20. In the initial state, the inner cover 16 is sealed with a preset amount of water. When the negative pressure component is not activated, there is no pressure difference between the inner cover 16 and the outer box 1. The tiny pores of the filter cotton 17 form a liquid bridge through the surface tension of water, preventing water from flowing out, so as to prevent water inside the inner cover 16 from leaking into the water flow channel 18 when stored statically. Activating the negative pressure component creates a pressure difference between the inner cover 16 and the outer box 1. Under the action of negative pressure, the water overcomes its surface tension and flows out evenly through the pores of the filter cotton 17. At this time, the filter cotton 17 filters the water flowing out from the inner cover 16. The filtered water flows into the water channel 18 between the inner cover 16 and the outer box 1. Under the negative pressure drive, it flows upward along the water channel 18 and is discharged through the water inlet 20 of the inner cover 16. The atomizing component is connected to the water inlet 20 through a pipe, atomizing 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 into the surrounding environment.

[0019] In this embodiment, the filter cotton 17 is ring-shaped and detachably connected to the outer casing 1. The bottom of the inner cover 16 is provided with a positioning part, which is used to fix the position of the filter cotton 17. The outer diameter of the positioning part is smaller than the outer diameter of the inner cover 16, and the cross-section of the positioning part is L-shaped. In the assembled state, the inner cover 16 presses down the filter cotton 17, and the filter cotton 17 is sleeved on the outside of the positioning part, so that the inner wall of the filter cotton 17 is in contact with the outer wall of the positioning part. The close fit design reduces the direct contact area between water and the filter cotton 17. At the same time, the length of the positioning part is less than the height of the filter cotton 17, so that water can only pass through from the bottom of the filter cotton 17 upward. When water permeates upward from the bottom of the filter cotton 17, the tiny pores of the filter cotton 17 can form a liquid bridge with the help of the surface tension of the water. The surface tension generated by the liquid bridge can generate sufficient resistance to prevent water from flowing out of the inner cover 16 in a static or low pressure difference state, thereby maintaining the preset water volume in the inner cover 16 and preventing water from leaking into the water flow channel 18.

[0020] In this embodiment, the top of the inner cover 16 has a certain thickness. The inner cover 16 is provided with a confluence port 31 and a water flow channel 19 corresponding to the number of water inlets 20. The front end of each water flow channel 19 is connected to the corresponding water inlet 20, and the end converges at the confluence port 31. This design can guide the water flow entering from different water inlets 20 to the confluence port 31 in an orderly manner, so as to realize the centralized collection of water flow. The inner cover 16 is formed with a ring-shaped positioning connection part 29. The confluence port 31 is located at the axis of the positioning connection part 29. A sealing element 30 with a T-shaped cross section is installed inside the confluence port 31. During assembly, the lower end of the sealing element 30 is embedded inside the confluence port 31. The outer wall of the sealing element 30 is tightly fitted with the inner wall of the positioning connection part 29. At the same time, there is a height gap between the end face of the sealing element 30 and the confluence port 31 to form a buffer chamber 32. When water flows into the confluence port 31 from the water inlet channel 26, the buffer chamber 32 can temporarily store part of the water flow, so that the water flow enters the subsequent water pump 34 and other components in a more stable state, thereby improving the stability of the entire water flow delivery system. The atomizing assembly includes a connector 27, a first water flow pipe 25, a second water flow pipe 25, a water pump 34, and an atomizing nozzle 9. The bottom of the connector 27 has a protrusion 28 and a connecting end 33 formed sequentially from the inside to the outside. The protrusion 28 is embedded inside the positioning connecting part 29, and the outer wall of the protrusion 28 is tightly fitted with the inner wall of the positioning connecting part 29. At the same time, the connector 27 presses the sealing part 30 tightly, and the connecting end 33 is inserted into the sealing part 30 and is interference-fitted with it. This design can effectively prevent water and air leakage, prevent outside air from entering under negative pressure environment, avoid water leakage under high pressure environment, maintain stable internal pressure of the device, and ensure sealing reliability. The connecting end 33 is hollow to form a water inlet channel 26. One end of the first water flow pipe 25 is fixedly mounted on the connector 27 and communicates with the water inlet channel 26. The other end is fixedly connected to the water inlet 20 of the water pump 34. One end of the second water flow pipe 25 is fixedly connected to the water outlet of the water pump 34. The other end is fixedly connected to the atomizing nozzle 9. The water pump 34 provides power for the water flow, sucks the water flow from the buffer chamber 32, pressurizes it, and discharges it from the water outlet. The atomizing nozzle 9 atomizes the pressurized water flow into fine water droplets to achieve the atomization function.

[0021] This embodiment also includes a fan mounting assembly, which includes a rotating base 2. The rotating base 2 is hollow to form a mounting cavity. Inside the mounting cavity, a battery module 43, a drive module 14, and a water pump 34 are fixedly connected to the rotating base 2. A connector 27 is fixedly connected to the water pump 34 by bolts. The drive module 14 is driven by a drive wheel located on the outside of the rotating base 2, and the rotating base 2 is provided with a driven wheel 40 rotatably connected to it. The bottom of the rotating base 2 is provided with a connecting shaft for rotatably engaging with the driven wheel 40. An internal gear ring 22 is fixedly mounted on the end face of the inner cover 16. The bottom end of the rotating base 2 is sleeved on the outside of the internal gear ring 22 and is not fixedly connected to it. There is a gap between the rotating base 2 and the outer casing 1 to form a rotational clearance. The drive wheel and the driven wheel 40... All are engaged with the gear protrusions of the internal gear ring 22. The drive module 14 drives the drive wheel to rotate. The drive wheel engages with the gear protrusions. Since the internal gear ring 22 is fixed, the circumferential force applied by the drive wheel to the internal gear ring 22 is fed back in the opposite direction by the internal gear ring 22, forming a reaction force that drives the rotating seat 2 to rotate. This reaction force is transmitted to the driven wheel 40 through the rotating seat 2. While the driven wheel 40 rotates around the connecting shaft, it converts the linear reaction force into the circumferential motion of the rotating seat 2 around the axis of the internal gear ring 22 through continuous engagement with the internal gear ring 22. Furthermore, the rotating seat 2 can rotate 360° relative to the inner cover 16. The battery module 43, drive module 14, water pump 34 and connector 27 rotate synchronously with the rotating seat 2, and the connecting end 33 rotates relative to the sealing member 30.

[0022] The fan mounting assembly in this embodiment also includes a mounting bracket 6 integrally formed with the rotating base 2. The upper end of the mounting bracket 6 is horizontally U-shaped, with the opening facing the fan assembly. The mounting bracket 6 is provided with two symmetrically distributed rotating shaft protrusions 48, and each rotating shaft protrusion 48 is provided with an angle limiting protrusion 47 on its outer periphery. The fan assembly includes a base frame 4, a front frame 56, a drive motor 10, and fan blades 8. The drive motor 10 is fixed to the base frame 4 with screws and is connected to the fan blades 8 for driving. The front frame 56 is fastened to the base frame 4 through a snap-fit ​​structure. The base frame 4 is provided with a shaft hole 53 that mates with a rotating shaft protrusion 48. The inner wall of the shaft hole 53 is provided with an abutment protrusion. The rotating shaft protrusion 48 is inserted into the shaft hole 53 to form a clearance fit. When the base frame 4 rotates relative to the mounting bracket 6 to the maximum angle, the angle limiting protrusion 47 contacts the abutment protrusion to limit the rotation range.

[0023] In this embodiment, a control circuit board 49 and multiple LED beads 55 are provided on the outer edge of the front frame 56. The control circuit board 49 is connected to the multiple LED beads 55 and is used to adjust the brightness, color and flashing frequency of the LED beads according to a preset program or external control signal. In addition, the front frame 56 is equipped with a light-transmitting plate 35, which covers the area where the control circuit board 49 and LED beads are located, and is used to protect the control circuit board 49 and LED beads, while ensuring that the light from the LED beads can be transmitted normally. The front frame 56 is provided with a hole 50 for the atomizing nozzle 9 to pass through.

[0024] In this embodiment, the inner cover 16 is provided with a water inlet 24, and the rotating seat 2 is provided with a flip cover 3 rotatably connected to it. A sealing plug is fitted on the side of the flip cover 3 facing the water inlet 24. When water needs to be added, the user rotates the flip cover 3, causing the flip cover 3 to rotate around the rotatable connection with the rotating seat 2. When the flip cover 3 is rotated to the appropriate position, the water inlet 24 is fully exposed. At this time, the user can add water to the water inlet 24 of the inner cover 16. After the water is added, the user rotates the flip cover 3 again, causing it to rotate in the opposite direction, until the sealing plug on the side of the flip cover 3 facing the water inlet 24 is tightly inserted into the water inlet 24, thereby sealing the water inlet 24 and preventing internal liquid leakage or external impurities from entering.

[0025] In this embodiment, the mounting bracket 6 is equipped with a main control circuit board 12, a charging interface 11, an indicator light 5, and multiple function buttons 7. The charging interface 11, function buttons 7, and indicator lights 5 are electrically connected to the main control circuit board 12 via wires. The charging interface 11 is located on one side of the mounting bracket 6, the indicator light 5 is located on the front of the mounting bracket 6, and the multiple function buttons 7 are arranged in a matrix below the indicator lights 5. The outer edge of the function buttons 7 is fitted with a sealing ring to prevent external moisture from entering the interior of the mounting bracket 6 and affecting the electrical connection.

[0026] In this embodiment, at least one sealing gasket 21 is provided at the connection between the inner cover 16 and the outer box 1. The inner cover 16 is provided with an air inlet 13 and at least one exhaust port 23. The negative pressure assembly includes an air inlet valve 15 located inside the air inlet 13, a drive wheel located above the air inlet 13, and a driven wheel 40 located above the exhaust port 23. When the drive module 14 is running, it drives the drive wheel to rotate, so that external gas enters the inner cover 16 through the air inlet valve 15. At the same time, the gas inside the inner cover 16 is discharged through the exhaust port 23.

[0027] In this embodiment, the mounting bracket 6 has an internal accommodating space. The accommodating space is provided with at least one locking block 42 for fixing the position of the water pipe 25. The locking block 42 has a shape and structure that matches the outer wall of the water pipe 25. When the water pipe 25 is placed in the mounting bracket 6, the locking block 42 can clamp and fix the water pipe 25 from at least one direction, ensuring the stability of the position of the water pipe 25 and effectively preventing the water pipe 25 from shifting due to water flow impact, equipment vibration and other factors, which would affect the normal transmission of water flow.

[0028] Compared to traditional technologies: The outer casing 1 is equipped with a ring-shaped filter cotton 17. The inner cover 16 has at least one water inlet 20 on its side. There is a gap between the outer wall of the inner cover 16 and the inner wall of the outer casing 1 to form a water flow channel 18. The water flow channel 18 is connected to the water inlet. On the one hand, after the filtered water enters the water flow channel 18 between the inner cover 16 and the outer casing 1, it flows upward along the water flow channel 18 under negative pressure and is discharged through the water inlet 20 of the inner cover 16. This design optimizes the water flow path, improves the flow efficiency of the water flow, reduces the risk of the entire water supply system being paralyzed due to pipe blockage, and reduces the possibility of failure. On the other hand, the filter cotton 17 is designed in a ring shape, which increases the effective contact area between the water flow and the filter cotton 17, so that the water can come into fuller contact with the filter cotton 17 during the flow process, thereby more effectively intercepting small particles, bacteria and impurities in the water, significantly improving the filtration efficiency, ensuring the cleanliness of the water entering the atomizing component, helping to improve the atomization quality, and reducing the damage to the atomizing device caused by water quality problems.
