Description

Technical Field

[0001] This utility model relates to the field of humidifying fans, specifically a humidifying fan. Background Technology

[0002] Currently, most humidifying fans on the market adopt a layout structure in which the water tank is placed below the fan, such as the humidifying fan disclosed in Chinese patent document CN216143896U. In this structure, the atomizing port is located on the lower side of the fan. When the water in the water tank is atomized, the water mist can be sprayed upward from the atomizing port below and drawn into the fan and blown out together, thereby achieving the humidification effect.

[0003] However, this structure still has some problems in practical applications.

[0004] First, this structure causes water mist to come into contact with the fan blades. When the fan stops, some water mist will still adhere to the blades. If this continues for a long time, the water mist adhering to the blades will form water droplets and drip down, resulting in damp ground or water accumulation.

[0005] Secondly, in some similar structures, in order to supply water from the low-level water tank to the high-level atomizing device, or to achieve the effect of spraying water mist, it is usually necessary to configure a pump and valve assembly. However, these pump and valve assemblies inevitably generate noise during operation, which not only affects the user experience, but also increases the overall energy consumption and maintenance cost of the equipment.

[0006] Therefore, it is necessary to develop a humidifying fan to prevent water mist from entering the fan and to reduce noise problems caused by pump and valve components. Utility Model Content

[0007] To address the aforementioned problems in the prior art where water mist enters the fan and the pump and valve assembly generates excessive noise, the technical solution adopted by this utility model is as follows:

[0008] A humidifying fan includes a fan body, wherein the fan body includes an atomizing water tank, a blowing device located on one side of the atomizing water tank, and a water storage tank communicating with the atomizing water tank, the water storage tank being located above the atomizing water tank, the blowing device having a fan chamber for mounting a fan, and an air outlet communicating with the fan chamber for discharging air, and the atomizing water tank having a water mist outlet for conveying water mist to the air outlet.

[0009] Furthermore, in the humidifying fan described in the solution, the atomizing water tank is located on the side of the air outlet, the water storage tank is arranged in a cuboid shape, and the water storage tank is horizontally placed above the atomizing water tank and the blowing device.

[0010] Furthermore, in the humidifying fan described in the solution, the atomizing water tank further includes a water mist emission component that is connected to the water mist outlet and the air outlet respectively. The air outlet is arranged horizontally, and the water mist emission component is arranged in a long strip shape and is positioned horizontally above the air outlet.

[0011] Furthermore, in the humidifying fan described in the solution, the water mist emission component is provided with a water mist emission port, which faces the air outlet and protrudes from the air outlet.

[0012] Furthermore, in the humidifying fan described in the solution, the length S1 of the water mist discharge port is less than the length S2 of the air outlet.

[0013] Furthermore, the humidifying fan described in the solution also includes an atomizing component attached to the outside of the atomizing water tank. The atomizing component is located at the bottom of the atomizing water tank, and the atomizing component uses ultrasonic vibration to cause the water in the atomizing water tank to form water mist.

[0014] Furthermore, the humidifying fan described in the solution also includes a cooling component attached to the outside of the atomizing water tank, and the bottom of the atomizing water tank is provided with an installation cavity, in which the cooling component is fixed.

[0015] Furthermore, in the humidifying fan described in the solution, the cross-section of the fan body is elongated along the horizontal plane.

[0016] Furthermore, the humidifying fan described in the solution also includes a flow guiding component located on one side of the air outlet. The flow guiding component is provided with a plurality of first flow guiding vanes arranged horizontally and capable of swinging up and down. The first flow guiding vanes are arranged in a wave-like shape.

[0017] Furthermore, in the humidifying fan described in the solution, the airflow guiding component is further provided with a plurality of second airflow guiding vanes that are vertically arranged and can swing left and right.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention places the water storage tank above the atomizing water tank, allowing water to automatically flow from the storage tank to the atomizing water tank under gravity. This avoids the noise problems associated with pump and valve assemblies, improves the user experience, and reduces the overall energy consumption and maintenance costs of the equipment. Furthermore, the blower device has a fan chamber connected to the air outlet, allowing the fan to be installed within the chamber and blow air through the outlet. The atomizing water tank also has a water mist outlet that delivers water mist directly to the air outlet, enabling the water mist to reach the outlet directly, be carried by the airflow, and evaporate rapidly for quick cooling. Simultaneously, it effectively prevents water mist from contacting the fan, thus avoiding water droplets forming on the fan blades and causing dampness or water accumulation on the ground.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example 1: As Figure 1-8 A humidifying fan is shown, including a fan body 5, wherein the fan body 5 includes an atomizing water tank 2, a blower 6 located on one side of the atomizing water tank 2, and a water storage tank 1 connected to the atomizing water tank 2. The water storage tank 1 is located above the atomizing water tank 2. The blower 6 is provided with a fan chamber 62 for installing a fan, and an air outlet 61 connected to the fan chamber 62 for discharging air. The atomizing water tank 2 is provided with a water mist outlet 25 for conveying water mist to the air outlet 61.

[0031] This invention places the water storage tank 1 above the atomizing water tank 2, allowing water in the storage tank 1 to automatically flow to the atomizing water tank 2 under gravity. This avoids the noise problem caused by using pump and valve components, improves the user experience, and reduces the overall energy consumption and maintenance costs of the equipment. In addition, the blower device 6 has a fan chamber 62 connected to the air outlet 61, allowing the fan to be installed in the fan chamber 62 and blow air through the air outlet 61. At the same time, the atomizing water tank 2 also has a water mist outlet 25 that delivers water mist to the air outlet 61, so that the water mist can directly reach the air outlet 61, be carried far by the airflow, and evaporate quickly to achieve a rapid cooling effect. At the same time, it can effectively prevent the water mist from contacting the fan, thus avoiding the problem of water mist adhering to the fan blades and forming water droplets that drip down, causing the ground to be wet or water to accumulate.

[0032] Specifically, this invention cleverly utilizes gravity by placing the water storage tank above the atomizing water tank, achieving automatic water transfer from the storage tank to the atomizing water tank without the need for a pump and valve assembly. Compared to the common humidifying fan structure on the market that places the water storage tank below the blower and uses a pump and valve assembly to supply water mist, this design reduces noise caused by the operation of the pump and valve assembly, providing users with a quieter and more comfortable operating environment, while also reducing the overall energy consumption and maintenance costs of the equipment. Furthermore, eliminating the pump and valve assembly also means... With the reduction in equipment failure rate, the maintenance burden on users is further reduced. Furthermore, by providing a fan chamber 62 in the blowing device 6 that communicates with the air outlet 61, the fan is installed in the fan chamber 62, and the atomizing water tank 2 is also provided with a water mist outlet 25 that delivers water mist to the air outlet 61. This allows the water mist output from the water mist outlet 25 to directly reach the air outlet 61 without passing through the fan. Therefore, the possibility of direct contact between the water mist and the fan is fundamentally prevented, thereby effectively avoiding the problem of water mist adhering to the fan blades and forming water droplets that drip down, causing the ground to be wet or water to accumulate.

[0033] Furthermore, in this embodiment, the water supply effect from the water storage tank 1 to the atomizing water tank 2 can be achieved through the pressure difference between the water storage tank 1 and the atomizing water tank 2. Specifically, this embodiment also includes a water outlet assembly connected to the water storage tank 1. The water storage tank 1 has an inner cavity and a water outlet communicating with the inner cavity. The water outlet assembly is used for a normally closed water outlet. The atomizing water tank 2 includes a drain assembly 4 that cooperates with the water outlet assembly to open the water outlet. The drain assembly 4 has a water outlet end near the bottom of the atomizing water tank 2, so that water from the water storage tank 1 flows into the atomizing water tank 2 through the water outlet end. Furthermore, the inner cavity of the water storage tank is only connected to the outside through the water outlet, while the water outlet assembly is sealed to the water outlet, ensuring that the inner cavity of the water storage tank is sealed when the water outlet assembly is closed or when it is filled with liquid. When the user fills the water storage tank 1 with water, the water outlet assembly of the water storage tank 1 is inserted into the drain assembly. In component 4, the water outlet is opened, allowing water in the inner cavity of the water storage tank to flow through the water outlet assembly and the water outlet assembly 4, and then into the atomizing water tank 2 through the water outlet end. At this time, water in the inner cavity of the water storage tank will continuously flow into the atomizing water tank 2. When the liquid level in the atomizing water tank 2 covers the water outlet end, it is equivalent to the inner cavity of the water storage tank being sealed. At this time, the inner cavity of the water storage tank is still under negative pressure, while the air pressure in the inner cavity of the atomizing water tank 2, which is connected to the outside, is greater than that in the inner cavity of the water storage tank. Therefore, the inner cavity of the water storage tank will stop supplying water to the atomizing water tank 2. When the water in the atomizing water tank 2 is consumed by atomization, the liquid level in the atomizing water tank 2 will drop, allowing air to continue to enter the inner cavity of the water storage tank 11 through the water outlet end, thereby allowing water in the inner cavity of the water storage tank to continue flowing into the atomizing water tank 2. This process is continuously cyclical, forming the effect that the water storage tank 1 will automatically supply water to the atomizing water tank 2, while controlling the liquid level height in the inner cavity of the atomizing water tank.

[0034] Furthermore, in some other embodiments, the water supply can be controlled by installing solenoid valves in the water storage tank 1 and the atomizing water tank 2, and an automatic water supply effect can be achieved in conjunction with a liquid level detection sensor.

[0035] Example 2: Further, such as Figure 1-8 The humidifying fan shown has an atomizing water tank 2 located on the side of the air outlet 61, and a water storage tank 1 arranged in a cuboid shape, which is horizontally placed above the atomizing water tank 2 and the blowing device 6.

[0036] This embodiment includes the features of Embodiment 1, the difference being that, by placing the atomizing water tank 2 on the side of the air outlet 61 and setting the water storage tank 1 as a cuboid structure horizontally above the atomizing water tank 2 and the blowing device 6, the structure of the humidifying fan is more compact, which not only improves the space utilization rate, but also, because the position of the water storage tank 1 is higher than that of the atomizing water tank 2, the water in the water storage tank 1 does not need to use a pump valve assembly, but can achieve the supply effect by gravity, further reducing noise and energy consumption.

[0037] Example 3: Further, such as Figure 1-8 The humidifying fan shown includes an atomizing water tank 2 that further includes a water mist emission assembly 26 that is connected to a water mist outlet 25 and an air outlet 61 respectively. The air outlet 61 is arranged horizontally, and the water mist emission assembly 26 is arranged in a long strip shape and is positioned horizontally above the air outlet 61.

[0038] This embodiment includes the features of Embodiment 2, the difference being that the present invention sets the air outlet 61 horizontally, making the horizontal width larger. This setting allows the airflow to be blown out more smoothly through the horizontally set air outlet 61, achieving a more uniform and wider coverage range, ensuring that the blown air can cover a larger area. Furthermore, the water mist emission component 26 is elongated and horizontally positioned above the air outlet 61. This setting ensures that the water mist sprayed from the water mist emission port 261 can evenly reach and distribute throughout the horizontally set air outlet 61, and fully diffuse with the airflow of the air outlet 61, improving the mixing efficiency of water mist and air and the humidification effect. Furthermore, since the water mist emission component 26 is located above the air outlet 61, the water mist sprayed from the water mist emission component 26 can flow fully towards the air outlet 61 under the action of gravity, thereby being fully carried away by the wind blown out by the blower 6, effectively improving the utilization rate of water mist and the humidification effect.

[0039] Example 4: Further, such as Figure 1-8 The humidifying fan shown has a water mist emission assembly 26 having a water mist emission port 261, which is open towards the air outlet 61 and protrudes from the air outlet 61.

[0040] This embodiment includes the features of Embodiment 3, the difference being that, by setting the direction of the water mist discharge port 261 to be the same as the opening direction of the air outlet 61, this utility model ensures that the water mist sprayed from the water mist discharge port 261 can directly enter the airflow generated by the blower device 6, maximizing the use of airflow to bring the water mist into the environment, thereby improving the diffusion efficiency and humidification effect of the water mist; furthermore, by setting the water mist discharge port 261 to protrude from the air outlet 61, the situation where the water mist accumulates on the blower device 6 under the action of gravity when it is discharged from the water mist discharge port 261 is avoided, thereby making full use of the water mist and further improving the humidification effect.

[0041] Example 5: Further, such as Figure 1-8 The humidifying fan shown has a water mist outlet 261 with a length S1 that is less than the air outlet 61 with a length S2.

[0042] This embodiment includes the features of Embodiment 4, the difference being that the length S1 of the water mist outlet 261 is set to be less than the length S2 of the air outlet 61, so that the water mist discharged from the water mist outlet 261 can be more concentrated in the air outlet area of ​​the air outlet 61, thereby mixing with the airflow and improving the contact efficiency and humidification effect of the water mist and the blown air; furthermore, since the water mist outlet 261 is relatively short, it can ensure that the water mist discharged from the water mist outlet 261 enters the area with the strongest airflow more concentratedly, avoiding the problem of weakened humidification effect caused by the water mist being too dispersed; furthermore, if the length S1 of the water mist outlet 261 is greater than the length S2 of the air outlet 61, it may cause the water mist to exceed the effective coverage range of the air outlet in the lateral distribution, so that some water mist may not be carried away by the airflow, resulting in the water mist depositing in the environment around the fan.

[0043] Example 6: Further, such as Figure 1-8 The humidifying fan shown also includes an atomizing component 27 attached to the outside of the atomizing water tank 2. The atomizing component 27 is located at the bottom of the atomizing water tank 2. The atomizing component 27 causes the water in the atomizing water tank 2 to form water mist through ultrasonic vibration.

[0044] This embodiment includes the features of Embodiment 5, the difference being that in this embodiment, the atomizing component 27 adopts a ceramic disc vibrating atomizer. By installing the ceramic disc vibrating atomizer at the bottom of the atomizing water tank 2, the ceramic disc vibrating atomizer can perform ultrasonic vibration on the water at the bottom of the atomizing water tank 2 to achieve water atomization. The water mist is then delivered to the air outlet 61 through the water mist outlet 25 above the atomizing water tank 2. The ceramic disc vibrating atomizer has the characteristics of high efficiency and low noise, and can achieve efficient water mist generation with low energy consumption. Furthermore, by setting the ceramic disc vibrating atomizer at the bottom of the outer side of the atomizing water tank 2, the vibration energy generated by the ceramic disc vibrating atomizer can be more effectively transferred to the water in the atomizing water tank 2, thereby achieving a more efficient atomization effect.

[0045] Example 7: Further, such as Figure 1-8 The humidifying fan shown also includes a cooling component 28 attached to the outside of the atomizing water tank 2. The bottom of the atomizing water tank 2 is also provided with a mounting cavity 29, and the cooling component 28 is fixed in the mounting cavity 29.

[0046] This embodiment includes the features of Embodiment Six, the difference being that, by setting a cooling component 28, the water in the atomizing water tank 2 can be cooled, thereby reducing the temperature of the atomized water mist and achieving the cooling and humidifying effect of the humidifying fan; furthermore, by placing the cooling component 28 at the bottom of the atomizing water tank 2, the temperature of the cooling component 28 can be transferred to the water at the bottom of the atomizing water tank 2 more efficiently, ensuring not only the cooling effect but also better control of the water temperature; furthermore, by setting a mounting cavity 29 for installing the cooling component 28, and the mounting cavity 29 being recessed at the bottom of the atomizing water tank 2, the contact area between the freezing temperature generated by the cooling component 28 and the bottom of the atomizing water tank 2 is increased, thereby improving the freezing effect.

[0047] Example 8: Further, such as Figure 1-8 The humidifying fan shown is wherein the fan body 5 has a long strip-shaped cross-section along the horizontal plane.

[0048] This embodiment includes the features of Embodiment Seven, the difference being that the cross-section of the fan body 5 is set as a long strip and is arranged along the horizontal plane. That is, the fan body 5 can be shaped as a cuboid, cylinder, or prism and placed horizontally on the table. This arrangement not only allows the fan body 5 to be placed horizontally in some narrow spaces on the table, but also makes it convenient for users to store. Furthermore, the fan body 5 can also be equipped with a wall-mounting component, so that users can hang the fan body 5 on the wall for use. Furthermore, the cuboid shape of the fan body 5 allows it to fit more tightly against the wall surface when hung on the wall, making the installation more stable and reliable, and preventing the fan body 5 from swaying left and right when blowing air. Furthermore, in some other embodiments, the fan body 5 can also be shaped as a cylinder. Furthermore, in some other embodiments, the fan body 5 can also be shaped as a prism.

[0049] Example 9: Further, such as Figure 1-8 The humidifying fan shown includes a flow guide assembly 7 located on one side of the air outlet 61. The flow guide assembly 7 is provided with a plurality of first flow guide vanes 71 arranged horizontally and capable of swinging up and down. The first flow guide vanes 71 are arranged in a wave shape.

[0050] This embodiment includes the features of Embodiment Eight, the difference being that the present invention provides a flow guiding component 7 on one side of the air outlet 61, and the flow guiding component 7 is provided with multiple horizontally arranged and vertically swingable first flow guiding vanes 71. This arrangement can effectively improve the uniformity of airflow distribution and coverage. Furthermore, the vertically swingable arrangement of the first flow guiding vanes 71 allows users to adjust the vertical airflow direction according to actual needs, ensuring that the humidified air can be effectively diffused to the designated area. Furthermore, the first flow guiding vanes 71 are arranged in a wave shape, and two adjacent first flow guiding vanes 71 are arranged symmetrically, forming a structure with staggered spaces of different sizes along the horizontal direction of the air outlet 61. When the airflow passes through these staggered and differently sized spaces, it can be divided into multiple uniform airflows, forming a more uniform airflow effect, avoiding the problem of excessively strong or weak local airflow that may be caused by traditional straight-plate flow guiding vanes. Furthermore, this arrangement helps to reduce the generation of turbulence and noise, making the blown airflow softer and more stable.

[0051] Example 10: Further, such as Figure 1-8 The humidifying fan shown is provided with a plurality of vertically arranged and swayable second air guide vanes 72.

[0052] This embodiment includes the features of Embodiment Nine, the difference being that the present invention further provides multiple vertically arranged and left-right swinging second guide vanes 72 on the air guiding component 7, allowing the user to adjust the angle of the second guide vanes 72 according to actual needs, thereby achieving airflow guidance in the left and right directions and ensuring that the humidified air can be evenly diffused to the required location; furthermore, through the arrangement of the first guide vane 71 and the second guide vane 72, the airflow can be adjusted in both horizontal and vertical directions, thereby achieving multi-angle and multi-directional airflow adjustment, further improving the user experience and comfort.
