Description

Technical Field

[0001] This application relates to the field of fans, and particularly to a humidifying fan. Background Art

[0002] In the hot summer, fans have become essential items for people to relieve the heat. In hot climates, to enhance the cooling effect of the fan, people will adopt a method of increasing the air humidity while increasing the air flow speed. Thus, a humidifying fan has emerged.

[0003] In the prior art, the structure commonly adopted by humidifying fans is: arranging the atomizing structure in front of the fan. When both the fan and the atomizing structure are in working state, the fan drives the atomized water vapor generated by the atomizing structure to move by blowing out air flow, achieving the effect of atomized air blowing.

[0004] The inventor of this invention found in the research that the air flow generated by the humidifying fan in the prior art when the fan is in working state will suppress the atomized water vapor located in front of it. Only a small amount of air flow on one side of the atomizing structure can drive the atomized air flow to move in coordination with it, and the air flow at other positions cannot contact the atomized water vapor. Therefore, the diffusibility of the atomized water vapor of the humidifying fan is not good. Utility Model Content

Making the outflow rate of the atomized water vapor positively correlated with the air outlet rate of the fan can make the outflow rate of the atomized water vapor match the actual use requirements, enhance the cooling effect of the humidifying fan, improve the adaptability of the humidifying fan to different use scenarios, and broaden the application scenarios of the humidifying fan.

[0037] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of the three-dimensional structure of the humidifying fan of this embodiment; Figure 2 This is a schematic diagram of the exploded structure of the humidification fan part of this embodiment.

[0038] like Figure 1 and Figure 2As shown in the figure, a humidifying fan includes: a fan housing 1, a fan assembly 2, a fan outer cover 3, a water tank 4, and an atomizing generator 52. A wind channel is formed inside the fan housing 1; the fan assembly 2 is arranged inside the fan housing 1; the fan outer cover 3 covers the fan housing 1 and is connected to the fan housing 1; the water tank 4 is connected to the fan outer cover 3, and an atomizing chamber 5 is formed in the water tank 4 and / or the fan outer cover 3; the atomizing generator 52 is connected to the water tank 4, one end of the atomizing generator 52 is arranged inside the atomizing chamber 5, and the other end of the atomizer is arranged inside the water tank 4; an atomizing air outlet 51 is formed on the fan outer cover 3, the atomizing air outlet 51 is communicated with the atomizing chamber 5, and the atomizing air outlet 51 is arranged around the fan air outlet 13 of the fan housing 1.

[0039] A wind channel is arranged inside the fan housing 1. The wind channel refers to the space formed inside the housing between the fan air inlet and the fan air outlet 13 for air flow. However, the structure of the wind channel is not limited to this. In some embodiments, the wind channel refers to the space inside the fan housing 1 through which the air flows during the process from the air entering the fan housing 1 to the air completely leaving the fan housing 1.

[0040] The water tank 4 refers to a container for holding liquid water or fragrance liquid. To facilitate adding the above liquids into the water tank 4, the water tank 4 and the fan housing 1 are connected in a detachable manner. The detachable connection methods include (but are not limited to): screw connection, snap connection, or magnetic coupling connection. However, the connection method between the water tank 4 and the fan housing 1 is not limited to this. In some embodiments, the water tank 4 can be fixedly connected to the fan housing 1, and a water injection port is formed on the water tank 4 or the water tank 4 is designed as an openable structure.

[0041] The atomizing generator 52 in this embodiment includes (but is not limited to): an ultrasonic atomizer, a vibrating atomizer, or a spray humidifier. Different types of atomizing generators 52 can be selected for use according to different specific application scenarios.

[0042] The fan assembly 2 in this embodiment includes: a fan motor and a fan blade. Among them, the fan motor is a three-phase motor. The three-phase motor has a higher speed and a larger adjustable speed range, so that the humidifying fan has more adjustment gears and stronger air supply capacity. In this embodiment, the fan motor adopts an outer rotor motor structure.

[0043] However, the specific type of the fan motor is not limited to this. According to different specific application scenarios, in some embodiments, the fan motor can be a two-phase motor, and the fan motor can adopt an inner rotor structure.

[0044] In this embodiment, the fan blade can be an axial-flow fan. However, the type of the fan blade is not limited to this. According to different specific application scenarios, in some embodiments, the fan blade can be an axial fan.

[0045] In the above humidifying fan, the atomizing chamber 5 is arranged in the water tank 4 and / or the fan housing 3. An atomizing generator 52 is arranged in the atomizing chamber 5. The atomizing air outlet 51 of the atomizing chamber 5 is arranged on the fan housing 3, and the atomizing air outlet 51 is arranged around the fan air outlet 13. When the air flow blows out from the fan air outlet 13, it can mix with the atomized water vapor at the atomizing air outlet 51. Since the atomizing air outlet 51 is arranged in a surrounding manner, the contact area between the blown air flow and the atomized water vapor can be increased, the mixing space between the blown air flow and the atomized water vapor is larger, and the mixing effect is better. At the same time, since the air flow blown out from the fan air outlet 13 is faster, a negative pressure area will be formed around the fan air outlet 13. The air pressure value in the negative pressure area is lower than the atmospheric pressure value, which will extract the atomized water vapor in the atomizing air outlet 51, accelerate the outflow rate of the atomized water vapor from the atomizing chamber 5, and make the outflow rate of the atomized water vapor match the air outlet rate of the fan. The outflow rate of the atomized water vapor is positively correlated with the air outlet rate of the fan. When the air outlet rate of the fan is high, the space where the air flow reaches is larger and more atomized water vapor is required. On the contrary, when the air outlet rate of the fan is low, the space where the air flow reaches is relatively small and the required atomized water vapor will also be correspondingly reduced. Making the outflow rate of the atomized water vapor positively correlated with the air outlet rate of the fan can make the outflow rate of the atomized water vapor match the actual use requirements, enhance the cooling effect of the humidifying fan, improve the adaptability of the humidifying fan to different use scenarios, and broaden the application scenarios of the humidifying fan.

[0046] In some embodiments, the opening direction of the atomizing air outlet 51 is perpendicular to the direction of air flow at the position of the fan air outlet 13.

[0047] The atomizing air outlet 51 in this embodiment is configured as an arc-shaped slit. However, the structure of the atomizing air outlet 51 is not limited thereto. According to different specific application scenarios, the structure of the atomizing air outlet 51 can be (but not limited to): circular, polygonal, oval, heart-shaped or holes of other shapes.

[0048] The number of the atomizing air outlets 51 in this embodiment can be (but not limited to): 1, 2, 3, 4, 5 or more.

[0049] The atomizing air outlet 51 is arranged between the inner housing 32 of the housing and the outer ring 33 of the housing. The slit structure makes the atomized water vapor relatively dispersed when blown out, reducing the interference of the atomized water vapor on the air flow blown out from the fan air outlet 13.

[0050] In some embodiments, the atomizing air outlet 51 can also be opened between the inner housing 32 of the housing, the outer ring 33 of the housing, the outer shell 31 of the housing or between the outer shell 31 of the housing and the outer ring 33 of the housing.

[0051] Please refer to Figure 3 and Figure 4 ,Figure 3 Schematic cross-sectional view of the humidifying fan of this embodiment; Figure 4 Front view schematic diagram of the humidifying fan of this embodiment.

[0052] As Figure 3 and Figure 4 shown, the atomizing air outlets 51 are circumferentially distributed around the fan air outlet 13, so that the air flow flowing out at each air outlet position can be mixed with the atomized water vapor flowing out from the atomizing air outlet 51 at the corresponding position. Compared with the traditional point-like atomization, more fan air flow can be mixed with the atomized water vapor, making the mixing effect of the blown air flow better and more uniform, and greatly improving the cooling effect of the humidifying fan.

[0053] The opening direction of the atomizing air outlet 51 is perpendicular to the direction of the air flow at the fan air outlet 13. The air flow flowing out at the fan air outlet 13 and the movement direction of the atomized water vapor flowing out from the atomizing air outlet 51 are perpendicular to each other. The atomized water vapor flows along its original movement direction and will collide perpendicularly with the fan air flow. This collision will make the fan air flow and the atomized water vapor fuse more fully, improve the mixing efficiency, and make the air flow and the atomized water vapor fuse more fully.

[0054] In some embodiments, the opening direction of the atomizing air outlet 51 is inclined towards the direction of the air flow at the fan air outlet 13, so that the intersection angle between the atomized water vapor flowing out of the atomizing air outlet and the air flow flowing out at the air outlet position is an acute angle.

[0055] The opening direction of the atomizing air outlet 51 is inclined towards the direction of the air flow blown out by the fan air outlet 13. The opening direction of the atomizing air outlet 51 is inclined, so that the movement direction of the atomized water vapor coming out of the atomizing air outlet 51 is inclined towards the water vapor blown out by the fan air outlet 13. This structure reduces the influence of the atomized water vapor coming out of the atomizing air outlet 51 on the air flow blown out by the fan air outlet 13. Because the atomized water vapor moves obliquely, its movement kinetic energy is decomposed into vertical kinetic energy perpendicular to the air flow of the fan air outlet 13 and horizontal kinetic energy of horizontal movement. The movement direction of the horizontal kinetic energy is the same as the movement direction of the air flow blown out by the fan air outlet 13. Therefore, this structure can reduce the impact of the atomized water vapor on the blown air flow and reduce the interference to the blown air flow. In this embodiment, the angle between the opening direction of the atomizing air outlet 51 and the horizontal line is 0 - 90°.

[0056] Please refer to Figure 7 , Figure 7 Schematic diagram of the outer cover base structure of this embodiment.

[0057] As Figure 7As shown, in some embodiments, the fan housing 3 extends towards the water tank 4 to form a housing base 311. The housing base 311 is connected to the water tank 4. The atomization chamber 5 is arranged inside the housing base 311. The atomization generator 52 is connected to the housing base 311, and the housing base 311 is provided with liquid leakage through holes 312 around the position where the atomization generator 52 is located.

[0058] One end of the atomization generator 52 is arranged inside the atomization chamber 5, protruding inside the atomization chamber 5, and the liquid leakage through holes 312 are arranged around the atomization generator 52. Specifically, the liquid leakage through holes 312 are configured in an arc shape and arranged around the atomization generator 52. However, the shape of the liquid leakage through holes 312 is not limited to this. According to different specific application scenarios, in some embodiments, the shape of the liquid leakage through holes 312 can be (but not limited to): circular, polygonal, elliptical, or other regular shapes.

[0059] In some embodiments, in order to better guide the liquid water formed by condensation, the bottom surface of the atomization chamber 5 where the liquid leakage through holes 312 are located is configured to be inclined, so that the water flow can better condense, converge and flow towards the water tank 4.

[0060] Due to factors such as a larger density and internal and external temperature differences, the atomized water vapor generated inside the atomization chamber 5 will condense into liquid water. The accumulation of liquid water will reduce the space inside the atomization chamber 5, or the liquid water will submerge the atomization generator 52 and make it unable to work. Setting the liquid leakage through holes 312 can guide the liquid water formed inside the atomization chamber 5 into the water tank 4, effectively avoiding the occurrence of the above adverse effects. It can also supplement the water in the water tank 4, reduce the number of times the user replenishes the water in the water tank 4, and improve the user experience.

[0061] In some embodiments, the fan housing 3 includes: an inner housing 32, an outer housing 31, and a housing ring 33. The inner housing 32 is connected to the fan housing. The outer housing 31 covers the inner housing 32. The housing ring 33 is arranged between the inner housing 32 and the outer housing 31 and is respectively connected to the inner housing 32 and the outer housing 31. The outer housing 31 extends towards the water tank 4 to generate the housing base 311.

[0062] By setting the fan housing 3 independent of the fan housing, the inner housing 32, the outer housing 31, and the housing ring 33 of the fan housing 3 form an independent space for guiding the atomized water vapor, which can prevent the atomized water vapor from entering the fan housing 1 and eroding or causing a short circuit to the electronic components inside the fan housing 1, further improving the safety of the atomization fan. At the same time, it can also extend the service life of the atomization fan.

[0063] In some embodiments, an atomization partition 53 is disposed inside the outer cover base 311. One end of the atomization partition 53 abuts against the inner shell 32 of the outer cover. The atomization partition 53 divides the outer cover housing into an atomization chamber 5 and an outdoor space 54.

[0064] The atomization partition 53 divides the space inside the outer cover base 311, so that the space inside the outer cover base 311 is divided into: an atomization chamber 5 and an outdoor space 54. The space inside the atomization chamber 5 is reduced, compressing the space where the atomized water vapor can diffuse, and thus reducing the time for the atomized water vapor to flow to the atomization air outlet 51. When the humidifying fan is started, only when the atomization chamber 5 is filled with atomized water vapor can the atomized water vapor diffuse along the direction from the atomization chamber 5 to the atomization air outlet 51. In the case of a smaller atomization space, the time for this atomization diffusion will be shortened. Therefore, the setting of the atomization partition 53 can reduce the "fogging" time of the humidifying fan and improve the timeliness of atomization and mixing of the humidifying fan.

[0065] In some embodiments, the atomization partition 53 is inclinedly disposed inside the outer cover base 311. Along the direction from the water tank 4 to the atomization air outlet 51, the space of the atomization chamber 5 gradually decreases.

[0066] The atomization partition 53 is inclined towards the atomization air outlet 51, so that the space on the horizontal section inside the atomization chamber 5 gradually decreases along the direction from the water tank 4 to the atomization air outlet 51. Similarly, the inclined setting of the atomization partition 53 plays a role in controlling the overall space inside the atomization chamber 5, further compressing the space inside the atomization chamber 5, and thus reducing the time for the atomized water vapor to flow to the atomization air outlet 51, improving the timeliness of atomization and mixing of the humidifying fan. Moreover, the inclined setting of the atomization partition 53 makes the space for the atomized water vapor to flow gradually decrease during the process of flowing out towards the atomization air outlet 51, thereby gradually increasing the flow velocity of the atomized water vapor, reducing the velocity difference between the atomized water vapor and the outflowing air current, making the mixing of the atomized water vapor and the outflowing air current more uniform, and making the cooling effect of the humidifying fan more obvious.

[0067] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the connecting frame of this embodiment.

[0068] As Figure 6 shown, in some embodiments, the humidifying fan further includes: a connecting frame 6. The connecting frame 6 is connected to the fan housing 1 through a plurality of air guide plates 61 arranged in a surrounding manner. The fan assembly 2 is connected to the connecting frame 6. A storage cover 62 is provided on one side of the connecting frame 6 opposite to the fan assembly 2. A storage bin 63 is formed between the storage cover 62 and the connecting frame 6.

[0069] The fan motor in the fan assembly 2 is connected to the connecting frame 6, and the fan blades are sleeved on the fan motor. A plurality of air guide plates 61 divide the fan air outlet 13 into a plurality of arc-shaped air outlets. In some embodiments, each arc-shaped air outlet is provided with a corresponding atomizing air outlet 51, and the arc curve length of the atomizing air outlet 51 is greater than the arc length of the arc-shaped air outlet. Since the air flow blown out from the arc-shaped air outlet will quickly spread and cover a larger space position after leaving the restraint of the arc-shaped air outlet, and the length of the atomizing air outlet 51 corresponding to the arc-shaped air outlet is larger, which corresponds to the space after the air flow spreads, so that the contact area between the atomizing air flow and the blown air flow is increased, and the mixing effect is better.

[0070] The shape of the storage cover 62 is configured as an arc. However, the shape of the storage cover 62 is not limited to this. According to different specific application scenarios, in some embodiments, the shape of the storage cover 62 can be (but not limited to): oval, polygon or other regular shapes.

[0071] In some embodiments, a battery assembly 7 is arranged in the storage bin 63, a battery bracket 64 is arranged in the storage bin 63, and a buffer member 71 is provided on the battery assembly 7. The buffer member 71 covers the contact position between the battery assembly 7 and the battery bracket 64, so that at least part of the structure of the battery assembly 7 is exposed.

[0072] A battery bracket 64 is arranged in the storage bin 63. The battery bracket 64 includes support plates arranged alternately horizontally and vertically. Battery notches are arranged on the support plates, and the shape of the battery notches fits the shape of the battery assembly 7, playing a role in clamping the battery.

[0073] In order to better protect the battery and reduce the influence of external forces on the stability and safety of the battery, a buffer member 71 is provided on the battery assembly 7. The buffer member 71 is made of (but not limited to): foam, fabric, paper sheet or other materials with buffering effects.

[0074] The buffer member 71 covers the contact position between the battery assembly 7 and the battery bracket 64. When the humidifying fan vibrates or collides, the acting force on the battery assembly 7 needs to be conducted through the battery bracket 64, and the buffer member 71 covers the contact position between the battery assembly 7 and the battery bracket 64, which can play the maximum protection role for the battery. And at the non-contact position between the battery bracket 64 and the battery assembly 7, the chance of being impacted and acted by external forces is very limited. Exposing this position will not only not reduce the safety protection effect on the battery, but also because the exposed position can better dissipate heat from the battery, improving the heat dissipation ability of the battery assembly 7.

[0075] In some embodiments, the battery assembly 7 can be arranged in the outdoor space 54.

[0076] In some embodiments, in order to increase the battery capacity of the humidifying fan, two sets of battery assemblies 7 are provided, which are respectively arranged in the outdoor space 54 and the storage bin 63.

[0077] In some embodiments, when two sets of battery assemblies 7 are provided, the power supply can be carried out in a separate power supply mode. One set of battery assembly 7 supplies power to the fan assembly 2, and the other set of battery assembly 7 supplies power to the rotary servo, the lighting device or other electrical devices provided in the humidifying fan. However, the power supply mode of the two sets of battery assemblies 7 is not limited to this. According to different specific application scenarios, in some embodiments, the two sets of batteries can be connected in series or in parallel and then supply power together.

[0078] In some embodiments, an air-increasing gap 34 is provided between the fan outer cover 3 and the fan housing 1. The gap distance of the air-increasing gap 34 at the first end 14 of the fan housing 1 is greater than the gap distance at the second end 15 of the fan housing 1.

[0079] The fan assembly 2 rotates to push the air flow entering the fan housing 1 towards the fan air outlet 13. After the air flow flows out of the fan air outlet 13, it has initial kinetic energy. The air flow with this initial kinetic energy will drive other air flows in the air that come into contact with it to flow. The air flow flowing out of the fan air outlet 13 will drive the air flow at the air outlet position of the fan outer cover 3 to move, and thus a negative pressure wind area is formed in the front position of the fan outer cover 3. Under the action of the atmospheric pressure, the air flow behind the fan outer cover 3 will flow into the air-increasing gap 34 and form a stable directional flow air flow. The air flow coming out of the air-increasing gap 34 will be driven by the air flow flowing out of the fan air outlet 13 to flow, thereby enhancing the wind force of the humidifying fan, increasing the air output of the humidifying fan, and improving the air output efficiency of the humidifying fan.

[0080] The first end 14 of the air-increasing gap 34 is the end facing away from the fan air outlet 13, and the second end 15 is the end opposite to the first section. The gap distance of the air-increasing gap 34 at the first end 14 of the fan housing 1 is greater than the gap distance at the second end 15 of the fan housing 1. This makes the flow space of the air flow in the air-increasing gap 34 gradually decrease, achieving the effect of pressurizing the air flow in the air-increasing gap 34 and making the initial velocity of the air flow finally flowing out of the air-increasing gap 34 higher.

[0081] Please refer to Figure 5 , Figure 5 which is a schematic diagram of the connection structure between the inner shell of the outer cover and the air guide housing of this embodiment.
