Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan with a humidification function. Background Art

[0002] As a common electrical product, fans can not only provide a comfortable living environment, but also play a key role in industrial production, helping to maintain the normal operation of equipment and improve production efficiency. In the prior art, fans are usually used in combination with humidifiers. For example, in the hot and dry climate in summer, humidification can be used to increase the coolness when using fans. When using electric heaters for heating in winter, the internal fan can be humidified to avoid excessive dryness of the air, thereby providing a more comfortable living environment.

[0003] Existing fans mainly use water mist humidification, for example, water is sprayed into tiny water mist particles through a high-pressure pump, or water is atomized into extremely fine water droplets through high-frequency oscillation. During the humidification process, the water mist may not evaporate completely, and the excess water usually flows back into the water tank. After multiple cycles, the water quality will deteriorate, and bacteria and odors will easily grow in the water tank. At this time, the air discharged by the fan may reduce the indoor air quality and affect the user experience. And because water mist is easily inhaled, untreated moisture may pose a health hazard to users and further affect the user experience.

[0004] Accordingly, the art needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve at least one of the above problems in the prior art, that is, to solve the problem that the reflux mechanism of the existing fan during humidification affects the user experience, the present application provides a fan with a humidification function, the fan comprising:

[0006] Supporting part;

[0007] A shell, the shell is arranged on the supporting part, the shell is provided with a groove at least at the bottom, and a heating element is arranged in the groove at the bottom;

[0008] A fan blade and a drive assembly, wherein the fan blade and the drive assembly are arranged on the housing, and the drive assembly is connected to the fan blade;

[0009] A humidifying component, the humidifying component is arranged on the housing, and the humidifying component is located above the groove at the bottom;

[0010] A water tank is used to supply water to at least the humidifying component.

[0011] When the above technical solution is adopted, when the fan is running, the wind takes away the moisture generated by the humidification component to increase the air humidity, and the excess moisture can flow into the groove and be evaporated by the heating element inside the groove, thereby achieving the drying of the inside of the fan and preventing the unevaporated moisture from flowing back into the water tank to cause bacteria to grow in the water tank and produce odor, thereby ensuring the air quality of the fan and improving the user experience. In addition, through the cooperation of the groove and the heating element, the heat generated by heating can also be used to achieve the heating function of the environment.

[0013] When the above technical solution is adopted, when the fan is running, wind can pass through the humidification cotton, thereby taking away the moisture in the humidification cotton, and then increasing the humidity in the air to achieve fogless humidification, avoiding the health risks caused by the water mist being inhaled into the body during spray humidification, and avoiding the degradation of environmental quality caused by the dirt, chlorine, dust and other harmful substances in the water being shaken out during vibration humidification, thereby ensuring a certain humidification effect while avoiding affecting the user experience.

[0014] In the preferred technical solution of the above-mentioned fan, a partition is further provided in the shell, and the partition is arranged around the outer periphery of the humidification bracket and the humidification cotton, and the groove is formed in the inner circumference of the partition, and the heating element is provided in at least the groove at the bottom; and / or

[0015] The humidifying cotton is located on the air inlet side of the fan blade.

[0016] When adopting the above technical solution, the humidifying cotton on the air inlet side can ensure that the air is fully humidified and then blown out of the shell, while the excess moisture on the humidifying cotton and the inner wall of the fan shell can directly flow into the groove. After humidification is completed, the heating element inside the groove starts heating to evaporate the moisture inside the groove, and combines with wind circulation to achieve dehumidification of the inside of the fan and the humidifying cotton.

[0017] In a preferred technical solution of the above-mentioned fan, the water tank is used to supply water to the humidifying component, or the water tank is used to supply water to the humidifying component and the groove.

[0018] When the above technical solution is adopted, the fan can also start heating while humidifying, or start heating after humidification is completed, so as to realize the heating function of the fan for the environment through the groove and the heating element.

The water tank is arranged above the humidifying component, and the humidifying cotton can be supplied with water by gravity without installing a water pump. This avoids the problem of increased cost caused by the need to install a water pump to supply water from the bottom water tank to the upper humidifying component, and the water pump may become blocked after long-term use. Therefore, the present application further reduces the maintenance cost of the fan.

[0022] In a preferred technical solution of the above-mentioned fan, the humidification bracket and the humidification cotton are rotatably arranged, and the rotation plane of the humidification bracket and the humidification cotton is parallel to the rotation plane of the fan blade.

[0024] In the preferred technical solution of the above fan, a first connecting hole is provided on the humidifying bracket, and a second connecting hole is provided on the humidifying cotton;

[0025] The driving assembly includes a motor and a speed-changing shaft, wherein the motor is connected to the fan blades, one end of the speed-changing shaft is connected to the motor, and the other end passes through the first connecting hole and the second connecting hole and is connected to the humidification bracket and the humidification cotton.

[0026] When the above technical solution is adopted, the fan blades and the humidification cotton can be linked by the speed-changing shaft, thereby avoiding the increase in cost caused by driving the humidification bracket and the humidification cotton by other driving components.

[0028] The water outlet is provided with a first sensor for detecting whether the water outlet is connected with the water inlet, and the water tank is configured to supply water when the water outlet is connected with the water inlet.

[0029] When adopting the above technical solution, the humidifying cotton rotates through the humidifying bracket. During the rotation process, when the first sensor detects that the water outlet is connected to the water inlet, the water tank supplies water to the humidifying cotton, and the water volume can be controlled by the cooperation of the water outlet and the water inlet to achieve quantitative humidification of the humidifying cotton and ensure the stable humidification effect of the humidifying cotton.

[0030] In the preferred technical solution of the above fan, the water inlet hole is provided in plurality; and / or

[0031] The drain outlet is provided in a plurality; and / or

[0032] The humidifying cotton is provided with a notch, the notch is arranged corresponding to the water inlet hole, and the notch and the water inlet hole are jointly surrounded to form a water seepage groove.

[0033] When the above technical solution is adopted, the water volume in the humidifying cotton can be ensured through multiple water inlet holes, and the humidifying bracket can be prevented from rotating too fast, resulting in a short connection time between the water inlet hole and the water outlet, thereby affecting the water addition volume. The water flow entering can be temporarily stored through the seepage groove to prevent the water flow from being thrown out during the rotation process, thereby further ensuring the humidification effect of the humidifying cotton.

[0043] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the humidification component is introduced in conjunction with the humidification cotton in this embodiment, this is not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may apply the present application to other application scenarios. For example, when the fan humidifies by spraying or ultrasonic oscillation, it can also achieve the processing of incompletely evaporated water through grooves and heating elements.

[0044] It should be noted that, in the description of the present application, the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "multiple" refers to at least two.

[0045] As described in the background technology, fans are common electrical products that not only provide a comfortable living environment, but also play a key role in industrial production, helping to maintain the normal operation of equipment and improve production efficiency. In the prior art, fans are usually used in combination with humidifiers. For example, in the hot and dry climate of summer, humidification can be used to increase the coolness when using fans. When using electric heaters for heating in winter, the internal fan can be humidified to avoid excessive dryness of the air when it is discharged, thereby providing a more comfortable living environment.

[0046] Existing fans mainly use water mist humidification, for example, water is sprayed into tiny water mist particles through a high-pressure pump, or water is atomized into extremely fine water droplets through high-frequency oscillation. During the humidification process, the water mist may not evaporate completely, and the excess water usually flows back into the water tank. After multiple cycles, the water quality will deteriorate, and bacteria and odors will easily grow in the water tank. At this time, the air discharged by the fan may reduce the indoor air quality and affect the user experience. And because water mist is easily inhaled, untreated moisture may pose a health hazard to users and further affect the user experience.

[0047] In order to solve the problem that the backflow mechanism of the existing fan during humidification affects the user experience, the present application provides a fan with a humidification function, including: a support part, a shell, fan blades, a drive assembly, a humidification assembly and a water tank, the shell is arranged on the support part, the shell is provided with a groove at least at the bottom, and a heating element is provided in the groove at the bottom, the fan blades and the drive assembly are arranged on the shell, and the drive assembly is connected to the fan blades, the humidification assembly is arranged on the shell, and the humidification assembly is located above the groove at the bottom, and the water tank is used to supply water to at least the humidification assembly.

[0048] When the above technical solution is adopted, when the fan is running, the wind takes away the moisture generated by the humidification component to increase the air humidity, and the excess moisture can flow into the groove and be evaporated by the heating element inside the groove, thereby achieving the drying of the inside of the fan and preventing the unevaporated moisture from flowing back into the water tank to cause bacteria to grow in the water tank and produce odor, thereby ensuring the air quality of the fan and improving the user experience. In addition, through the cooperation of the groove and the heating element, the heat generated by heating can also be used to achieve the heating function of the environment.

[0049] Refer to the following Figures 1 to 6 , the fan with humidification function of the present application is described. Among them, Figure 1 This is the overall structural diagram of the fan of this application; Figure 2 A front view of the fan of the present application; Figure 3 A cross-sectional view of the fan of the present application; Figure 4 A schematic diagram of a humidification bracket of the present application; Figure 5 A schematic diagram of the humidifying cotton of the present application; Figure 6 This is a schematic diagram of the separator and humidification component of the present application.

[0050] like Figures 1 to 6As shown, in a preferred embodiment, the fan includes a support portion 10, a shell 20 and a water tank 30, wherein the support portion 10 includes a base 11 and a support rod 12, the bottom of the support rod 12 is connected to the base 11, and the top of the support rod 12 is connected to the shell 20. The shell 20 is provided with a fan blade 21, a drive assembly 22, a humidification assembly 23, a sterilization assembly 24 and a filter assembly 25. The humidification assembly 23 is located on the air inlet side of the fan blade 21, and the humidification assembly 23 includes a humidification bracket 231 and a humidification cotton 232, and the humidification cotton 232 is arranged in the humidification bracket 231, and the humidification bracket 231 and the humidification cotton 232 can rotate and their rotation planes are parallel to the rotation plane of the fan blade 21. Specifically, the driving assembly 22 includes a motor 221 and a driving rod 222. The motor 221 is connected to the fan blade 21. One end of the driving rod 222 is connected to the motor 221. A first connecting hole 2311 is opened at the center of the humidifying bracket 231. A second connecting hole 2321 is opened at the center of the humidifying cotton 232. The other end of the driving rod 222 passes through the first connecting hole 2311 and the second connecting hole 2321 to be connected to the humidifying bracket 231 and the humidifying cotton 232.

[0051] The humidifying bracket 231 is provided with a plurality of water inlet holes 2312 and a plurality of drainage holes 2313. The water inlet holes 2312 are used to dock with the water outlet 31. The humidifying cotton 232 is provided with a plurality of notches 2322 corresponding to the water inlet holes 2312. The water tank 30 includes a box body 31 and a cover body 32. The box body 31 is provided at the top of the housing 20. The cover body 32 is located at the top of the box body 31, and one end of the cover body 32 is hinged to the box body 31. The bottom of the box body 31 is provided with a water outlet 31. A first sensor 33 is provided at the water outlet 31. The first sensor 33 is used to detect whether the water outlet 31 is connected with the water inlet hole 2312. A second sensor 34 is provided in the box body 31. The second sensor 34 is used to detect the water level in the box body 31.

[0052] In this embodiment, the filter component 25 includes a filter element 251 and a purification element 252. When the motor 221 drives the fan blades 21 to rotate, the wind first passes through the filter element 251 to be initially filtered, then passes through the purification element 252 to be efficiently filtered, and then passes through the sterilization component 24, the humidification component 23 and the fan blades 21 before being blown out of the shell 20. Among them, since the motor 221 is connected to the humidifying component 23 through the driving rod 222, the humidifying component 23 can be linked with the fan blade 21 during the rotation of the fan blade 21. During the rotation, multiple water inlet holes 2312 are connected with the water outlet 31 in sequence. When the first sensor 33 detects that the water outlet 31 is connected to the water inlet hole 2312, the water tank 30 supplies water to the humidifying cotton 232. Optionally, a control valve is provided at the water outlet 31. When the first sensor 33 detects that the water outlet 31 is connected to the water inlet hole 2312, the first sensor 33 sends a signal to the control valve, the control valve opens, and the water tank 30 starts to supply water to the humidifying cotton 232. The water flows through the water outlet 31, flows through the water inlet hole 2312 and the notch 2322, and is absorbed by the humidifying cotton 232. During the rotation of the humidifying bracket 231 and the humidifying cotton 232, the humidifying cotton 232 can achieve uniform humidification.

[0053] It needs to be explained that Figure 3 and Figure 4As shown, in this embodiment, the water inlet 2312 protrudes outward relative to the body of the humidifying bracket 231, so the first sensor 33 can adopt a general photoelectric sensor. Specifically, a light emitter and a receiver are installed face to face on both sides below the water outlet 31. The light emitter can emit infrared light or visible light, and the light receiver can receive light without obstruction. However, when the water inlet 2312 is rotated to communicate with the water outlet 31, the water inlet 2312 blocks the light. At this time, the photoelectric switch outputs a signal to control the water supply of the water tank 30, thereby controlling the water tank 30 to supply water to the humidifying cotton 232. However, the specific setting of the first sensor 33 is not fixed, and those skilled in the art can select the type of the first sensor 33 according to needs, as long as it does not affect the realization of the normal function of the first sensor 33. In an alternative embodiment, a sonic sensor is provided below the water outlet 31, and the distance between the humidifying bracket 231 and the obstacle on the side can be measured by emitting sonic waves toward the side facing the humidifying bracket 231. When the water inlet 2312 rotates to communicate with the water outlet 31, the measured distance changes, and it is determined that the water inlet 2312 is connected with the water outlet 31. In another alternative embodiment, the first sensor 33 can be set as a proximity sensor, which detects the distance between the sensor and the water inlet 2312 without physical contact, so as to determine whether the water inlet 2312 rotates to a position relative to the water outlet 31. In addition, in this embodiment, a second sensor 34 is provided in the water tank 30, which can be used to detect the water level in the water tank 30 and issue a reminder when the water in the water tank 30 is insufficient. In this embodiment, the second sensor 34 is set as a float type water level sensor, and the float is made of a light material such as a sponge block. As the water level changes, the float will float up and down. When the float drops to a certain position, the sensor switch can be triggered and a reminder signal can be issued. However, its setting is not necessary. Those skilled in the art can change the specific setting of the second sensor 34 according to their needs. In an alternative embodiment, a light transmitter and a receiver can be installed face to face at the bottom of the box 31. When the water level is normal, the light emitted by the transmitter will be refracted on the water surface, causing the receiver to be unable to receive the light; when the water level drops to the set water level, the light will be directly reflected back into the receiver, and the sensor will judge that there is no water and send out a warning signal. In another alternative embodiment, the second sensor 34 is set as a pressure sensor. When the detected pressure drops to a certain threshold, it is determined that the water level is lower than the preset water level line. Of course, those skilled in the art can also omit the second sensor 34.

[0054] It is also necessary to explain that the humidification component is usually located at the top of the fan machine, while in the prior art, for the counterweight of the fan, the water tank is usually set at the bottom of the fan machine. When the user adds water to the water tank, he needs to bend down to add water to the water tank. When the fan is running the humidification function, it needs to supply water from the bottom water tank to the upper humidification device through a water pump. This water supply method not only increases the cost, but also may cause clogging problems after the water pump is used for a long time. In this embodiment, the water tank 30 is set at the top of the housing 20, and the user can add water to the fan without bending down, thereby providing convenience for the user, and the water tank 30 is set above the humidification component 23, and the humidification cotton 232 can be supplied with water by the gravity of the water, without installing a water pump, thereby reducing the cost of the whole machine, and avoiding the maintenance of the water pump and other problems, reducing the maintenance cost, but the setting position of the water tank 30 is not fixed, and those skilled in the art can also supply water to the humidification cotton 232 in this embodiment through the bottom water tank and water pump.

[0055] Of course, when the water tank 30 is set on the top of the shell 20, the humidification method of the humidifying cotton 232 is not fixed. In a replaceable embodiment, the setting of connecting the driving rod 222 and the humidifying component 23 can be omitted. The humidifying cotton 232 can be humidified in a static state, and the setting of the first sensor 33 can be omitted at this time. A valve body can be set at the water outlet 31 to control the water flow rate to ensure the stable humidification of the humidifying cotton 232. However, considering the humidification effect of the humidifying cotton 232, humidifying the humidifying cotton 232 by rotating the humidifying bracket 231 is a better choice. In addition, when the humidifying cotton 232 is set to be static, the humidifying cotton 232 can also be tilted relative to the fan blades 21, so as to increase the contact area between the wind and the humidifying cotton 232, thereby improving the humidification effect. At this time, those skilled in the art can also omit or change the specific setting of the humidifying bracket 231, as long as the humidifying cotton 232 is fixed. In the case of setting the humidifying bracket 231, such as Figure 4As shown, although three water inlet holes 2312 are evenly arranged on the humidifying bracket 231 in this embodiment, this is not necessary. Those skilled in the art can change the number and setting position of the water inlet holes 2312 according to needs. At this time, those skilled in the art can control the water supply to the humidifying cotton 232 by controlling the rotation speed of the driving rod 222 and the number of water inlet holes 2312. In this embodiment, the driving rod 222 and the motor 221 can be connected by a magnetic coupling, and the magnetic field strength at the connection is changed only by changing the current output by the motor 221, thereby controlling the rotation speed of the driving rod 222. At this time, the rotation speed of the fan blade 21 remains unchanged. Of course, in order to ensure that the water flow has enough time to flow into the water inlet hole 2312, the rotation speed of the humidifying component 23 is usually less than the rotation speed of the fan blade 21. In addition, when the humidifying cotton 232 is set to be rotatable, the driving mode of the humidifying component 23 is not necessary. In an alternative embodiment, another motor can be used to provide power to the humidifying component 23, and the rotation speed of the humidifying component 23 can be controlled by the motor alone.

[0056] like Figure 3 and Figure 6 As shown, a partition 26 is provided inside the housing 20, and the partition 26 is arranged around the outer periphery of the humidifying bracket 231 and the humidifying cotton 232. A groove 261 is formed in the inner circumference of the partition 26, and a heating element is provided in the groove 261 at the bottom. During the operation of the fan, the water thrown out by the humidifying cotton 232 during the rotation process can flow into the groove 261 and be collected at the bottom. When the fan completes humidification, the driving rod 222 can be controlled to disconnect from the motor 221. At this time, the humidifying component 23 stops rotating, and the excess water in the humidifying cotton 232 flows to the groove 261 at the bottom through the drainage hole 2313 on the humidifying bracket 231 under the action of gravity. The heating element in the groove 261 starts heating to evaporate the water. At this time, the heat generated by the heating can be discharged through the rotation of the fan blade 21, thereby achieving the drying of the humidifying cotton 232 and the inside of the housing 20, and avoiding the humidifying cotton 232 and the inside of the housing 20 from producing bacteria and odor due to incomplete dehumidification, which affects the user experience. In this embodiment, the rotation speed of the driving rod 222 can be controlled to 0 by controlling the current to 0. Of course, its setting is not necessary. In a possible embodiment, the driving rod 222 is set as a retractable driving rod. At this time, the humidification component 23 is rotatably set on the shell 20 or the partition 26. During the humidification process, the driving rod 222 extends into the first connecting hole 2311 and the second connecting hole 2321. During the heating and dehumidification process, the driving rod 222 extends out of the first connecting hole 2311 and the second connecting hole 2321.

[0057] It should be explained that in the prior art, since the water mist may not evaporate completely during the humidification process, the excess water usually flows back into the water tank, which will cause the water quality to deteriorate after multiple cycles, and the water tank is prone to breeding bacteria and producing odor. In this embodiment, after the humidification is completed, the humidification cotton 232 can be controlled to be in a static state. At this time, the moisture inside the humidification cotton 232 is discharged to the groove 261 under the action of gravity, and the heating element set at the groove 261 evaporates the excess moisture. At this time, the fan blade 21 remains in a rotating state, and the heat generated by the heating can be used to dry the humidification cotton 232 and then discharged from the housing 20 through the fan blade 21, and the technicians in this field assist the fan to realize the heating function for the environment by changing the heating area of ​​the groove 261. Specifically, the heating wire laid inside the groove 261 can be used to achieve heating, but the setting of the groove 261 is not necessary. In an alternative embodiment, the technicians in this field can change the heating method of the groove 261 according to the needs, for example, a heating element such as a PTC heating plate is set at the bottom of the groove 261. In another alternative embodiment, a heating element is provided inside the groove 261, and when water vapor is distributed on both sides of the groove 261, the side wall can also be evaporated by the heating element. In another alternative embodiment, the setting of the heating element can be omitted, that is, the storage of excess water is completed only by the structure of the groove 261 itself. At this time, the excess water is not heated and evaporated, and the moisture in the humidification cotton 232 and the groove 261 is only dried by the flowing wind. However, considering the dehumidification effect of the inside of the housing 20 and the humidification cotton 232, it is a better choice to set the groove 261 and the heating element. In addition, if the fan is used as a heating device, the groove 261 can also start heating while the humidification component 23 rotates, so as to realize the heating function for the environment. At this time, the fan can realize humidification while heating to avoid the problem of excessive dryness of the air caused by heating and affecting the user experience, and the water tank 30 can also supply water to the groove 261 through a separate water supply passage. In addition, the specific settings of the humidification component 23 and the groove 261 are not static. In an alternative embodiment, when the fan humidifies through the humidification cotton 232, the partition 26 can also be set to a semi-circular shape. However, considering that the water flow may be thrown to the inner wall of the shell 20 during the rotation of the humidification cotton 232, the annular partition 26 is used to prevent the water flow at the inner wall from being blown to the side toward the fan blade 21, thereby ensuring that the groove 261 can fully evaporate the excess moisture in the humidification cotton 232. Therefore, setting the partition 26 to a ring shape is a better choice.In another alternative embodiment, the groove 261 may also be formed by the shell 20 being concave. In this case, the groove 261 may be arranged in parallel with the humidifying cotton 232, or may be arranged along the inlet and outlet directions of the fan. For example, when the fan is humidified by spraying or ultrasonic oscillation, the water droplets remaining inside the fan flow along the inner wall into the groove arranged along the inlet and outlet directions. The contaminated water flow may be evaporated by the groove and the heating element inside it to prevent the backflow from affecting the water quality in the water tank. However, when humidifying by spraying, the untreated water is refined into spray and is easily inhaled. When humidifying by ultrasonic oscillation, the dirt, chlorine, dust and other harmful substances in the water may be shaken out, resulting in a decrease in environmental quality and affecting the user experience. Therefore, humidification by humidifying cotton 232 is a better choice.

[0058] It can be understood by those skilled in the art that, although the humidifying cotton 232 in this embodiment is provided with a notch 2322 opposite to the water inlet hole 2312, those skilled in the art can omit the notch 2322 according to the needs. However, considering that the notch 2322 can temporarily store the water flow entering through the water inlet hole 2312 to prevent the water flow after entering the water inlet hole 2312 from being thrown out of the humidifying bracket 231, thereby ensuring the humidification effect of the humidifying cotton 232, it is a better choice to set the notch 2321 on the humidifying cotton 232. In addition, the setting of the drainage hole 2313 on the humidifying bracket 231 is not fixed. Those skilled in the art can also change the number and setting position of the drainage hole 2313 according to the needs. In an alternative embodiment, the setting of the drainage hole 2313 can be omitted. At this time, the water inlet hole 2312 can also play a role in drainage during the rotation process. However, considering the drainage effect of the humidifying cotton 232, setting the drainage hole 2313 is a better choice.

[0059] It should be explained that, in this embodiment, the filter element 251 can be set as a filter, the purification element 252 can be set as a purification filter element, and the sterilization component 24 can be set as an ultraviolet sterilization device. The air can be purified by the filter component 25 and the sterilization component 24, thereby realizing the combination of the fan and the air purification function, and avoiding the problem of contamination of the humidification cotton 232 during the operation of the fan, thereby avoiding the impact of the humidification cotton 232 on the health of the user after long-term use, and ensuring the user's experience. Of course, the specific settings of the filter component 25 and the sterilization component 24 are not static. In an alternative embodiment, a person skilled in the art can omit the settings of the filter component 25 or the sterilization component 24. In another alternative embodiment, a person skilled in the art can change the specific settings of the filter component 25 and the sterilization component 24 according to needs. For example, the sterilization of the fan air intake can be completed by negative ion sterilization.

[0060] It is also necessary to explain that, in this embodiment, Figure 3 As shown, when the user adds water to the water tank 30, the user can lift the right side of the cover 32 upwards. At this time, since the cover 32 rotates counterclockwise relative to the connection between the left side of the cover 32 and the box 31, after the water is added, the right side of the cover 32 is covered with the right side of the box 31. However, the specific setting of the water tank 30 is not fixed, and those skilled in the art can change it according to needs. In an alternative embodiment, the box 31 can be slidably connected to the cover 32. In addition, although in this embodiment, the support part 10 includes a base 11 and a support rod 12, that is, the fan machine exhibits the structure of a general floor fan, the base 11 is mainly used for counterweight, and the support rod 12 mainly realizes the connection between the base 11 and the housing 20, but the specific setting of the support part 10 is not necessary, and those skilled in the art can change the structure of the support part 10 according to needs. In this case, the fan can be set as a small desktop fan. In addition, those skilled in the art can also apply the humidification method of the present application to other fans, humidifiers or air purifiers as needed, and although the fan is used to provide cool air in this embodiment, those skilled in the art can apply the humidification method of the present application to a heater as needed.

[0061] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0062] So far, the technical solutions of the present application have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
