Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0057] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0058] The invention provides a fan which has multiple functions and high humidification efficiency.

[0059] See also Figures 1 to 4In one embodiment of the present invention, the fan 10 includes a fan head 100, a bracket assembly 200 and a humidifying device 300, the fan head 100 includes a mesh cover 110 and a fan blade 120, and the fan blade 120 is rotatably disposed in the mesh cover 110; the bracket assembly 200 includes a support member 210 and a base 220, the fan head 100 is disposed on the support member 210, and the support member 210 is disposed on the base 220; the humidifying device 300 is disposed on the base 220 for generating water mist, and the humidifying device 300 has a mist outlet 310, and the mist outlet 310 is spaced apart from the fan head 100 and is located below the fan head 100.

[0060] It is understandable that the mesh cover 110 has an air inlet end, an air outlet end and an air flow channel, and the fan blade 120 is rotatably disposed in the air flow channel of the mesh cover 110. Air enters the mesh cover 110 from the air inlet end of the mesh cover 110 as the fan blade 120 rotates, and is discharged from the air outlet end of the mesh cover 110 after passing through the air flow channel, so as to achieve the function of blowing cold air. The fan head 100 is disposed on the support member 210, and the mesh cover 110 and the support member 210 can be fixedly connected or rotatably connected. In this embodiment, the mesh cover 110 is rotatably disposed on the support member 210, and the rotation axis of the mesh cover 110 is disposed in the horizontal direction.

[0061] In one embodiment, the mesh cover 110 is rotatably arranged on the support 210, and the rotation axis of the mesh cover 110 is arranged in the horizontal direction. It can be understood that the fan 10 also includes an up and down shaking driving mechanism, which is connected to the mesh cover 110 and the support 210 respectively to drive the mesh cover 110 to rotate relative to the support 210; the specific structure of the up and down shaking driving mechanism is not limited here. In one embodiment, the up and down shaking driving mechanism includes a horizontal shaft, a first driving motor, a first driving gear and a first transmission gear, the first driving gear is sleeved on the power output shaft of the first driving motor, the first driving gear and the first transmission gear are meshed, the first transmission gear is arranged in the vertical direction, the first driving motor is installed in the support 210, the horizontal shaft is fixedly connected to the first transmission gear, the horizontal shaft is installed on the mesh cover 110 through a bearing, and the mesh cover 110 is rotatably connected to the support 210 through the horizontal shaft. In this way, the fan 10 realizes the up and down shaking function.

[0062] Further, the support member 210 is disposed on the base 220, and the support member 210 and the base 220 may be fixedly connected or rotatably connected. In this embodiment, the support member 210 is rotatably disposed on the base 220, and the rotation axis of the support member 210 is disposed along the vertical direction. The fan 10 further includes a left and right shaking driving mechanism, which is respectively connected to the base 220 and the support member 210 to drive the support member 210 to rotate relative to the base 220. The structure of the left and right shaking drive mechanism is not limited. In one embodiment, the left and right shaking drive mechanism includes a vertical rotating shaft, a second driving motor, a second driving gear, and a second transmission gear. The second driving motor is installed in the base 220, and the second driving gear is sleeved on the power output shaft of the second driving motor. The second driving gear and the second transmission gear are meshed, and the second transmission gear is arranged in the horizontal direction. The vertical rotating shaft is fixedly connected to the second transmission gear. The vertical rotating shaft is installed in the support member 210 through a bearing. The support member 210 is rotatably connected to the base 220 through the vertical rotating shaft. With this arrangement, the function of the fan 10 shaking left and right is realized.

[0063] Furthermore, the humidifying device 300 is used to generate water mist, which is discharged outward through the mist outlet 310. The opening direction of the mist outlet 310 can be set upward, and of course it can also be set directly in front of the fan 10, or diagonally in front, so that the water mist can diffuse with the air flow, thereby humidifying the air.

[0064] Furthermore, the mist outlet 310 is spaced apart from the mesh cover 110 of the fan head 100, and is located below the mesh cover 110. The fan blades 120 rotate to drive the air flow around the fan head 100, and the air flow drives the water mist to flow and diffuse outward along the air flow direction of the fan 10, thereby realizing the function of the fan 10 to humidify the air. The humidification method can be electric evaporation humidification, or ultrasonic atomization humidification, which is not specifically limited here. In this solution, no mist guide pipe is provided between the mist outlet 310 and the fan head 100, thereby avoiding the situation where the water mist in the mist guide pipe condenses and refluxes and affects the humidification efficiency when the humidifying device 300 is provided with a mist guide pipe. The structures of the humidifying device 300 and the fan head 100 are simple, and the structure between the two is concise, thereby simplifying the structure of the fan 10 and making the fan 10 have a certain aesthetics.

[0065] The fan 10 of the present invention comprises a fan head 100, a bracket assembly 200 and a humidifying device 300. The fan head 100 comprises a mesh cover 110 and a fan blade 120. The fan blade 120 is rotatably arranged in the mesh cover 110 to achieve the function of blowing cold air. The bracket assembly 200 comprises a support member 210 and a base 220. The fan head 100 is arranged on the support member 210. The support member 210 is arranged on the base 220 to support the fan head 100. The humidifying device 300 is arranged on the base 220 to generate water mist. That is, the fan 100 of the present application 0 also has the function of humidifying air; the humidifying device 300 has a mist outlet 310, which is spaced apart from the fan head 100 and is located below the fan head 100. This arrangement allows the water mist sprayed from the mist outlet 310 to diffuse into the air along with the airflow blown out by the fan head 100, thereby humidifying the air. That is, no mist guide tube is provided between the mist outlet 310 and the fan head 100 in this solution, thereby avoiding the condensation and reflux of the water mist in the mist guide tube and affecting the humidification efficiency. The humidifying device 300 of this application has a simple structure and high humidification efficiency. It can be seen that the fan 10 of this application has the function of humidifying air in addition to the function of blowing cold air, and the humidifying device 300 has a simple structure and high humidification efficiency.

[0066] See also Figures 1 to 4 In one embodiment, the humidifying device 300 includes a shell, an atomizing sheet 340 and a fan 350, the shell having an atomizing chamber 320, a mist guiding channel 330 and the mist outlet 310 connected in sequence; the atomizing sheet 340 is arranged in the atomizing chamber 320 to atomize the water in the atomizing chamber 320; the fan 350 is arranged in the shell and / or the base 220, and the fan 350 is used to send air into the atomizing chamber 320 so that the water mist in the atomizing chamber 320 is discharged from the mist outlet 310 after being guided by the mist guiding channel 330.

[0067] It can be understood that the atomizer sheet 340 can be an ultrasonic atomizer sheet, which is electrically connected to the controller of the fan 10. The atomizer sheet 340 uses electronic high-frequency oscillation based on the ultrasonic principle to break up the liquid water molecular structure to form water mist, thereby ensuring the humidification amount. At the same time, the atomizer sheet 340 can be replaceably arranged in the atomization chamber 320, so that the structure of the humidification device 300 is simple and easy to manufacture.

[0068] Furthermore, the user can add water to the atomizing chamber 320 so that the atomizing sheet 340 can atomize the water into water mist. In another embodiment, the housing further has a water storage chamber 360, which is connected to the atomizing chamber 320. The user can add water to the water storage chamber 360, and the water will flow into the atomizing chamber 320 so that the atomizing sheet 340 can atomize the water into water mist. An air inlet can be provided on the base 220 or the housing of the fan 10, and the fan 350 can be provided at the air inlet. The number of fans 350 can be set as needed, and the number can be one or more, which is not limited here.

[0069] Specifically, the controller of the fan 10 controls the atomizing sheet 340 to work, and the controller also controls the fan 350 to operate, so as to blow air into the atomizing chamber 320, and the water in the water storage chamber 360 flows into the atomizing chamber 320 for the atomizing sheet 340 to atomize; a mist outlet is formed on the housing to connect the atomizing chamber 320 and the mist guide channel 330. When the air needs to be humidified, the controller controls the fan 350 to rotate, so as to blow air into the atomizing chamber 320. Under the action of the airflow, the water mist in the atomizing chamber 320 passes through the mist outlet and enters the mist guide channel 330. The mist guide channel 330 guides the airflow and the water mist, so as to discharge the water mist from the mist outlet 310, and the discharged water mist humidifies the air. In this embodiment, the air inlet can be arranged at the bottom of the base 220 or on the side wall of the shell, and the mist outlet 310 can be arranged at the top of the shell, so as to ensure that under the action of the fan 350, the water mist in the atomizing chamber 320 can be completely discharged from the mist outlet 310; the mist guide channel 330 is hidden in the shell, and compared with the prior art that sets a mist guide pipe to guide the water mist to the air outlet side of the mesh cover 110, the length of the mist guide channel 330 of this solution is shorter, which avoids the situation that the length of the mist guide pipe set in the prior art is too long, and part of the water mist will condense and reflux along the pipe wall of the mist guide pipe and affect the humidification efficiency. This solution is conducive to improving the humidification effect. In addition, the mist guide channel 330 improves the smoothness of the flow of water mist. Under the pressurization of the fan 350, the speed at which the water mist is sprayed outward is faster, which is conducive to improving the uniformity of the humidified air.

[0070] In one embodiment, the mist guide channel 330 is extended in the up-down direction, and the mist outlet 310 is arranged at the top of the housing. Such an arrangement makes the resistance of the water mist flowing in the mist guide channel 330 small, and the water mist can flow smoothly toward the mist outlet 310, thereby improving the smoothness of the water mist flow.

[0071] In one embodiment, a mist outlet connecting the atomizing chamber 320 and the mist guiding channel 330 is formed in the shell, and the mist outlet is arranged toward the side wall of the shell. Specifically in this embodiment, the side wall direction of the shell is the horizontal direction, that is, the opening direction of the mist outlet is arranged toward the horizontal direction. With such an arrangement, the mist outlet opened toward the horizontal direction connects the atomizing chamber 320 and the mist guiding channel 330, thereby preventing the airflow blown out from the mist outlet from blowing directly upward. When the airflow containing water droplets passes through the mist outlet and enters the mist guiding channel 330, the water droplets will collide with the side wall of the mist guiding channel 330 under the action of the airflow and flow back into the atomizing chamber 320, thereby preventing the water droplets from being blown out directly from the mist outlet 310, thereby ensuring the effect of water mist humidification.

[0072] In one embodiment, an air inlet is provided on the base 220 , and the plane where the highest point of the air inlet is located is lower than the plane where the mist outlet 310 is located, thereby ensuring that all the water mist in the atomization chamber 320 can be discharged from the mist outlet 310 .

[0073] In one embodiment, the shell further has a water storage chamber 360 connected to the atomizing chamber 320 , and the water storage chamber 360 is used to supply water to the atomizing chamber 320 . The water storage chamber 360 is arranged in a ring shape around the circumference of the mist guiding channel 330 .

[0074] It can be understood that the water storage chamber 360 is arranged in a ring around the mist guide channel 330, so that the internal space of the shell can be fully utilized, so that the structures of the mist guide channel 330 and the water storage chamber 360 are compactly arranged, and the mist guide channel 330 is extended in the up and down directions, and the mist outlet 310 is arranged at the top of the shell, so that the water mist can flow smoothly toward the mist outlet 310; at the same time, the mist guide channel 330 is also hidden in the shell. Compared with the prior art in which a mist guide pipe is set to guide the water mist to the mesh cover 110, the length of the mist guide channel 330 of this scheme is shorter, which avoids the situation that the length of the mist guide pipe set in the prior art is too long, and part of the water mist will condense and reflux along the tube wall of the mist guide pipe to affect the humidification efficiency. This scheme is conducive to improving the humidification effect.

[0075] In one embodiment, the mist guiding channel 330 includes at least a gradually expanding section, and the inner diameter of the gradually expanding section gradually increases from bottom to top. Such a configuration is conducive to the smooth upward flow of the water mist and facilitates the outward diffusion of the water mist.

[0076] See also Figures 7 to 12 In one embodiment, the fan 10 further includes a heating element 400, which is disposed in the mesh cover 110 and between the fan blades 120 and the air inlet end of the mesh cover 110, so as to heat the air.

[0077] It is understandable that the heating element 400 is arranged at the air inlet side of the fan blade 120. When the fan blade 120 rotates, cold wind is sucked from the air inlet end of the mesh cover 110, and becomes hot wind after being heated by the heating element 400, and then blown out from the air outlet end of the mesh cover 110 with the rotation of the fan blade 120. The hot wind is scattered by the rotation of the fan blade 120, and the hot wind blown out is uniform, which is conducive to improving the comfort of the user. The type and shape of the heating element 400 are not limited here. The heating element 400 can be a heating wire 420, or a heating pipe, or other objects that can generate heat. When the fan 10 is in the warm air mode, the heating element 400 works to heat the air flowing along the air flow channel of the mesh cover 110, and the heated air is discharged from the air outlet end of the mesh cover 110 with the rotation of the fan blade 120, so that the fan 10 can blow out warm air, that is, the fan 10 of the present application has the function of heating.

[0078] See also Figures 7 to 11 In one embodiment, the fan 10 further includes a plurality of overheat protectors 500, which are disposed in the mesh cover 110 and are electrically connected to the heating element 400, respectively, so as to respectively protect the heating element 400 from overheating. The plurality of overheat protectors 500 are arranged in sequence along the extension direction of the air flow channel of the mesh cover 110, and at least one of the overheat protectors 500 is disposed on the air outlet side of the heating element 400.

[0079] It can be understood that multiple overheat protectors 500 are electrically connected to the heating element 400 respectively, and multiple overheat protectors 500 respectively protect the heating element 400 from overheating. Multiple overheat protectors 500 correspond to various abnormal working conditions of the heating wire 420. Multiple overheat protectors 500 are arranged in sequence along the extension direction of the air flow channel of the mesh cover 110. For example, one of the overheat protectors 500 is arranged on the peripheral side of the heating element 400, one of the overheat protectors 500 is arranged on the air outlet side of the heating element 400, or one of the overheat protectors 500 is arranged on the air inlet side of the heating element 400. The specific settings can be made as needed.

[0080] When one of the overheat protectors 500 cannot sense the rapid temperature rise of the heating element 400 in time, another overheat protector 500 among the multiple overheat protectors 500 arranged in sequence along the extension direction of the airflow channel can sense the rapid temperature rise of the heating element 400 in time. In other words, corresponding to different temperature rise states of the heating element 400, the multiple overheat protectors 500 arranged in sequence along the extension direction of the airflow channel can correspond to different temperature rise states of the heating element 400, thereby being able to sense the overheating of the heating element 400 in time and then perform overheating power-off protection to ensure the safety of the use of the fan 10.

[0081] It should be noted that one of the overheat protectors 500 is disposed on the air outlet side of the heating element 400. The air outlet side here refers to the air outlet side of the heating element 400 when the air passes through the heating element 400. Figure 7 In the figure, air enters the mesh cover 110 from the rear cover 114 and passes through the heating element 400 and then blows out from the front cover 113. At this time, the rear cover 114 is located upstream of the heating element 400, and the front cover 113 is located downstream of the heating element 400. The side of the heating element 400 facing the front cover 113 is the air outlet side of the heating element 400, and vice versa.

[0082] When the fan 10 tilts its blades 120 and cannot rotate normally, the heating element 400 continues to work, and the heat accumulates on the heating element 400. The overheating protector 500 provided on the air outlet side of the heating element 400 can quickly sense the sharp rise in the temperature of the heating element 400. When the temperature exceeds the preset protection value of the overheating protector 500, the overheating protector 500 performs overheating protection on the heating element 400 and cuts off the power to avoid fire, electric shock, etc. caused by overheating of the heating element 400, thereby ensuring the safety of the use of the fan 10.

[0083] In addition, the overheat protector 500 includes a temperature limiter and / or a fuse. The temperature limiter is used to automatically cut off the power supply of the limiter when the temperature is too high. The temperature limiter is a resettable thermostat. The fuse is used to melt its own fuse when the temperature is too high. When the overheat protector 500 includes a temperature limiter and a fuse, the heating element 400, the temperature limiter and the fuse are connected in series in sequence. The melting temperature of the fuse is higher than the power-off temperature of the temperature limiter. At this time, the fuse is a double insurance for the heating element 400, which is conducive to improving the safety of the fan 10.

[0084] It can be seen that a plurality of overheat protectors 500 are arranged in the air flow channel and are electrically connected to the heating element 400 respectively, so as to protect the heating element 400 from overheating. When the heating element 400 is in an overheating state of abnormal operation, a plurality of overheat protectors 500 arranged in sequence along the extension direction of the air flow channel and at least one overheat protector 500 is provided on the air outlet side of the heating element 400, which can timely sense the rise in the temperature of the heating element 400 and disconnect the circuit to avoid the problem that the heat of the heating element 400 cannot be dissipated in time and overheating causes fire and electric shock when the fan 10 falls or the fan blades 120 stop rotating. That is, the fan 10 of this solution can prevent the occurrence of fire, electric shock and other problems caused by overheating of the heating element 400, thereby improving the safety of the fan 10. It can be seen that in addition to the function of blowing air, the fan 10 of this solution has high safety performance.

[0085] In one embodiment, the plurality of overheat protectors 500 include a first overheat protector 510 and a second overheat protector 520 , wherein the first overheat protector 510 is disposed on the peripheral side of the heating element 400 , and the second overheat protector 520 is disposed on the air outlet side of the heating element 400 .

[0086] It is understandable that the mesh cover 110 has an air inlet end and an air outlet end relative to each other, and the fan 10 has a front and a rear end. When the air outlet end of the mesh cover 110 faces the front of the fan 10, that is, on the positive projection surface of the heating element 400, if the fan blade 120 stops rotating or rotates slowly due to a fault, the heating element 400 heats up rapidly, and the heat generated by the heating element 400 flows upward, and the first overheat protection provided on the side of the heating element 400 can timely and sensitively sense the temperature rise of the heating element 400, thereby quickly powering off the heating element 400, so that the first overheat protector 510 can protect the heating element 400 from overheating. Among them, the first overheat protector 510 is provided on the side of the upper half of the heating element 400, so as to further improve the induction sensitivity of the first overheat protection.

[0087] Furthermore, when the fan 10 falls over, the air outlet end of the mesh cover 110 is facing obliquely upward or obliquely downward, that is, when the air outlet end of the mesh cover 110 is at an elevation angle or a depression angle, the heating element 400 is also inclined, and the second overheating protector 520 is arranged on the air outlet side of the heating element 400. When the fan blades 120 stop rotating or rotate slowly due to a malfunction, the heating element 400 heats up rapidly, and the heat generated by the heating element 400 will flow upward. At this time, the second overheating protector 520 is closer to the heating element 400, and the hot air flow will pass through the second overheating protector 520. In this way, the second overheating protection can promptly and sensitively sense the temperature rise of the heating element 400, thereby quickly cutting off the power to the heating element 400 for protection. It can be seen that when the fan 10 is tilted, the second overheat protector 520 is arranged on the air outlet side of the heating element 400 and can promptly and sensitively perform overheating power-off protection on the heating element 400. This solution ensures the safety of the use of the fan 10 by cooperating with the first overheat protector 510 and the second overheat protector 520.

[0088] In one embodiment, the first overheat protector 510 and the second overheat protector 520 are arranged at intervals and / or staggered along the extension direction of the airflow channel of the mesh cover 110. It can be understood that the first overheat protector 510 and the second overheat protector 520 are arranged at intervals along the extension direction of the airflow channel, so that the temperatures of the first overheat protector 510 and the second overheat protector 520 do not interfere with each other, which is conducive to the accuracy of the temperatures sensed by the first overheat protector 510 and the second overheat protector 520 respectively.

[0089] Furthermore, the first overheat protector 510 and the second overheat protector 520 are staggered along the extension direction of the airflow channel, which not only allows the two to have a sufficient spacing, but also allows the two to have different distances from the heating element 400. This is beneficial for corresponding to different tilt positions of the heating element 400. When one of the first overheat protector 510 and the second overheat protector 520 is close to the heating element 400, it can timely and sensitively sense the temperature rise of the heating element 400, thereby being able to quickly cut off the power supply to protect the heating element 400, thereby improving the safety of the use of the fan 10.

[0090] See also Figures 9 to 11 In one embodiment, the heating element 400 includes a heating bracket 410 and a heating wire 420, the heating wire 420 is arranged on the outer peripheral wall of the heating bracket 410 and forms an accommodating gap 430 with the heating bracket 410, and the first overheat protector 510 is arranged on the heating bracket 410 and located in the accommodating gap 430.

[0091] It is understandable that the number of heating wires 420 can be set as needed, for example, the number of heating wires 420 can be one circle, two circles, or multiple circles. In the present embodiment, the number of heating wires 420 is two circles. By providing a receiving notch 430 on the heating element 400 for the installation of the first overheating protector 510, the structure of the heating element 400 is fully utilized, and there is no need to reserve a receiving space for the first overheating protector 510 in the mesh cover 110, thereby improving the space utilization rate inside the mesh cover 110. In addition, the first overheating protector 510 is arranged in the receiving notch 430, so that the distance between the first overheating protector 510 and the heating wire 420 is relatively close, and the first overheating protector 510 can quickly sense the temperature rise of the heating wire 420, which is conducive to improving the sensing sensitivity of the first overheating protector 510. In addition, when the accommodation notch 430 is located on the circumference of the upper half of the heating element 400, that is, when the first overheat protector 510 is located on the circumference of the upper half of the heating element 400, the fan blade 120 stops rotating or rotates slowly due to a fault, the heating element 400 heats up rapidly, and the heat generated by the heating wire 420 flows upward and passes through the first overheat protector 510, so that the first overheat protector 510 can accurately and sensitively sense the temperature rise change, and then the first overheat protector 510 can quickly cut off the power supply to the heating wire 420. It can be seen that this solution is conducive to improving the reliability of the first overheat protector 510 in protecting the heating element 400.

[0092] In one embodiment, the second overheat protector 520 is disposed on the heating bracket 410 and outside the receiving notch 430. The second overheat protector 520 is disposed downstream of the first overheat protector 510 along the direction of the airflow channel and is offset from the first overheat protector 510. With such an arrangement, when the fan 10 falls over and the heating wire 420 tilts, the second overheat protector 520 disposed outside the receiving notch 430 and downstream of the first overheat protector 510 is closer. At the same time, the second overheat protector 520 is offset from the first overheat protector 510, so that the second overheat protector 520 can quickly and sensitively sense the temperature rise of the heating wire 420, so that the second overheat protector 520 can quickly cut off the power supply to the heating wire 420, thereby improving the reliability of the second overheat protector 520 and also improving the safety of the fan 10.

[0093] In addition, the second overheat protector 520 is arranged downstream of the upper half of the heating element 400. In this arrangement, when the fan blade 120 stops rotating or rotates slowly due to a fault, the heating element 400 heats up rapidly, and the heat generated by the heating wire 420 flows upward and passes through the second overheat protector 520, so that the second overheat protector 520 can accurately and sensitively sense the temperature rise change and cut off the power supply to protect the heating wire 420. It can be seen that this solution is conducive to improving the safety of the fan 10.

[0094] In order to improve the accuracy and sensitivity of the first overheat protector 510 in sensing temperature, please refer to Fig.11 In one embodiment, on the orthographic projection plane of the heating element 400, the angle between the line connecting the first overheat protector 510 and the center line of the heating element 400 and the horizontal plane is M, wherein 25°≤M≤65°.

[0095] It can be understood that, on the orthographic projection surface of the heating element 400, the line connecting the first overheat protector 510 and the center line of the heating element 400 is L1, the line on the horizontal plane is L2, and an angle M is formed between L1 and L2. By limiting the size of the angle M, the position of the first overheat protector 510 relative to the heating wire 420 is also limited. Limiting the position of the first overheat protector 510 is conducive to improving the sensitivity of the sensing temperature and being able to quickly and accurately sense the change of temperature rise, thereby quickly powering off the heating wire 420. Among them, the angle M can be 25°, or 30°, or 40°, or 45°, or 50°, or 60°, or 65°, etc., which are specifically defined herein.

[0096] In one embodiment, the mesh cover 110 has relative air inlet and outlet ends, and when the air outlet end faces the front of the fan 10, the first overheat protector 510 and / or the second overheat protector 520 are arranged above a line parallel to the horizontal plane and passing through the center line of the heating element 400.

[0097] In such a configuration, that is, when the air outlet end is facing the front of the fan 10, the first overheat protector 510 and / or the second overheat protector 520 are arranged above L2, that is, the first overheat protector 510 is arranged on the peripheral side of the upper half of the heating element 400, and / or the second overheat protector 520 is arranged on the air outlet side of the upper half of the heating element 400. As can be seen from the above, when the heating element 400 is overheated and the fan 10 is facing straight ahead, the heat generated by the heating element 400 will flow upward and pass through the first overheat protector 510. At this time, the first overheat protector 510 can accurately and sensitively sense the temperature rise change and cut off the power to the heating wire 420; and when the fan 10 falls over and the heating element 400 is tilted, the heat generated by the heating element 400 will flow upward and pass through the second overheat protector 520. At this time, the second overheat protector 520 can accurately and sensitively sense the temperature rise change and cut off the power to the heating wire 420. The first overheat protector 510 and the second overheat protector 520 cooperate with each other to ensure the safety of the use of the fan 10.

[0098] See also Fig. 9 and Fig.10 In one embodiment, the first overheat protector 510 includes a first temperature limiter 511, which is connected in series with the heating element 400; the second overheat protector 520 includes a second temperature limiter 521, which is connected in series with the heating element 400 and in parallel with the first temperature limiter 511.

[0099] It can be understood that the first temperature limiter 511 is connected in series with the heating element 400 to form a first circuit, so that the first temperature limiter 511 can independently perform position limiting protection on the heating element 400. The first temperature limiter 511 is used to automatically cut off the power when the temperature is too high. The first temperature limiter 511 is a resettable thermostat.

[0100] Furthermore, the second temperature limiter 521 is used to automatically cut off the power when the temperature is too high, and the second temperature limiter 521 is a resettable thermostat; the second temperature limiter 521 is connected in series with the heating element 400 to form a second circuit, and the second temperature limiter 521 is connected in parallel with the first temperature limiter 511, that is, the second circuit is connected in parallel with the first circuit. Such an arrangement enables the second temperature limiter 521 to independently perform position limiting protection on the heating element 400, and the second temperature limiter 521 and the first temperature limiter 511 do not interfere with each other, so that they can correspond to different temperature rise states of the heating element 400 to improve the safety of the fan 10 when using the warm air function.

[0101] In one embodiment, the first overheat protector 510 also includes a first fuse 512, which is connected in series with the first temperature limiter 511, and the first fuse 512 is connected in parallel with the second temperature limiter 521; and / or, the second overheat protector 520 also includes a second fuse 522, which is connected in series with the second temperature limiter 521, and the second fuse 522 is connected in parallel with the first temperature limiter 511.

[0102] It is understandable that the first fuse 512 is used to melt its own fuse when the temperature is too high. The first fuse 512 is connected in series to the first circuit, and the first fuse 512 is connected in parallel with the second circuit, that is, the first fuse 512 and the first temperature limiter 511 can provide double protection for the heating element 400, that is, double insurance for the heating element 400, thus improving the reliability of the first overheat protector 510.

[0103] Similarly, the second fuse 522 is used to melt its own fuse when the temperature is too high. The second fuse 522 is connected in series to the second circuit, and the second fuse 522 is connected in parallel with the first circuit, that is, the second fuse 522 and the second temperature limiter 521 can provide double protection for the heating element 400, that is, double insurance for the heating element 400, thus improving the reliability of the second overheat protector 520.

[0104] In one embodiment, the temperature limit protection range of the first temperature limiter 511 is 50° C. to 100° C., and / or the temperature limit protection range of the second temperature limiter 521 is 70° C. to 130° C. This configuration is used to protect the heating element 400 from overheating, thereby preventing fire, electric shock, etc. caused by overheating of the heating element 400, thereby ensuring the safety of the fan 10.

[0105] In one embodiment, the fusing temperature range of the first fuse 512 is 50°C to 150°C; and / or the fusing temperature range of the second fuse 522 is 70°C to 180°C. With such a configuration, the heating element 400 is further protected from overheating. It is understandable that when the first fuse 512 is applied to the first circuit, the fusing temperature of the first fuse 512 is greater than the protection temperature of the first temperature limiter 511, that is, the first temperature limiter 511 first protects the heating element 400 from overheating. When the first temperature limiter 511 fails, the first fuse 512 protects the heating element 400 from overheating, that is, double insurance for the heating element 400. Similarly, when the second fuse 522 is applied to the second circuit, the melting temperature of the second fuse 522 is greater than the protection temperature of the second temperature limiter 521, that is, the second temperature limiter 521 first protects the heating element 400 from overheating. When the second temperature limiter 521 fails, the second fuse 522 then protects the heating element 400 from overheating, that is, double insurance for the heating element 400.

[0106] See also Figure 7 , Fig.12 and Fig.13 In one embodiment, the fan 10 further includes a heat insulating member 600 , which is disposed in the mesh cover 110 and sleeved outside the heat generating member 400 along the axial direction of the fan blade 120 .

[0107] It is understandable that the heat insulating member 600 can be arranged in an annular shape, and the heat insulating member 600 is used to isolate the heat generated by the heating element 400 to prevent the heat from being transferred to the mesh cover 110. In particular, when the fan blade 120 stops rotating due to a fault, or the speed of the fan blade 120 decreases, and the fan 10 fails to work, if the heat insulating member 600 is not provided, the heat of the heating element 400 will be transferred to the mesh cover 110 or an object outside the mesh cover 110, thereby causing a safety accident such as a fire. This solution is beneficial to improving the safety performance of the fan 10 by sleeve-arranging the heat insulating member 600 outside the heating element 400 along the axial direction of the fan blade 120. In this embodiment, the center line of the heat insulating member 600 coincides with the rotation axis of the fan blade 120, which is beneficial to improving the consistency of the fan 10.

[0108] In addition, the heat insulating member 600 also has the function of gathering heat. When the heating element 400 heats the air, the heat generated by the heating element 400 is gathered in the heat insulating member 600 to prevent the heat from spreading arbitrarily. The fan blades 120 rotate to take away the gathered heat, which is beneficial to improving the heating effect of the fan 10. In addition, by providing the heat insulating member 600, the heat on the mesh cover 110 is relatively low, so that the mesh cover 110 can be made of a material with a lower heat resistance than the heat insulating member 600. Since the material usage of the mesh cover 110 is greater than the material usage of the heat insulating member 600, the mesh cover 110 is made of a material with a lower heat resistance, which is beneficial to reducing the manufacturing cost of the fan 10.

[0109] See also Fig.14 and Fig.15 In one embodiment, the distance between the heating element 400 and the heat insulating element 600 in the radial direction of the fan blade 120 is D1, wherein 5mm≤D1≤25mm. It can be understood that when the distance between the heating element 400 and the heat insulating element 600 is close, the heat insulating element 600 will affect the smoothness of air flow; when the distance between the heating element 400 and the fan blade 120 is far, it will affect the heat insulation and heat gathering effect of the fan 10. This solution limits the distance between the heating element 400 and the heat insulating element 600 in the radial direction of the fan blade 120, so that the air can flow smoothly in the heat insulating element 600 and the heat insulation effect is better. Among them, D1 can be 5mm, or 10mm, or 12mm, or 15mm, or 18mm, or 20mm, or 22mm, or 25mm, etc., which is not specifically limited here.

[0110] See also Figure 4 , Figure 7 , Fig.14 and Fig.15 In one embodiment, the mesh cover 110 has a middle shell portion 111 which is arranged in an annular shape, the upper half of the middle shell portion 111 is arranged in a closed shape, and the lower half of the middle shell portion 111 is provided with an air inlet 112 .

[0111] It is understandable that the mesh cover 110 may include a front cover 113 and a rear cover 114, the front cover 113 and the rear cover 114 are detachably connected, and the middle shell portion 111 is a part of the front cover 113 or the rear cover 114; in another embodiment, the mesh cover 110 includes a front cover 113, a middle shell and a rear cover 114, the front cover 113 and the middle shell are detachably connected, the middle shell and the rear cover 114 are detachably connected, and the middle shell includes the middle shell portion 111. In other words, the specific structure of the mesh cover 110 is not limited, and the middle shell portion 111 only needs to be a part of the mesh cover 110. In this embodiment, the mesh cover 110 includes a front cover 113, a middle shell and a rear cover 114. The side of the front cover 113 facing away from the rear cover 114 is an air outlet end, and the side of the rear cover 114 facing away from the front cover 113 is an air inlet end. The middle shell is arranged between the front cover 113 and the rear cover 114. The middle shell includes a middle shell part 111. The upper half of the middle shell is closed. The lower half of the middle shell is provided with an air inlet 112. The air inlet 112 includes a plurality of air inlet holes. The plurality of air inlet holes are arranged in sequence on the side wall of the lower half of the middle shell, thereby forming the air inlet 112.

[0112] Furthermore, by providing an air inlet 112 at the lower half of the middle shell 111, when the fan 10 is in the cold air mode, air can enter not only from the air inlet end of the mesh cover 110, but also from the air inlet 112 at the lower half of the middle shell 111. The air inlet end of the mesh cover 110 and the air inlet 112 are both beneficial to increasing the amount of cold air entering and ensuring the wind speed of the cold air, so that the fan 10 has a better cold air effect. When the fan 10 is in the warm air mode, the air is heated after entering the mesh cover 110, and the density of the hot air is small, so the weight The amount of air is light and rises upward. Since the upper half of the middle shell 111 is closed, the hot air in the mesh cover 110 cannot directly pass through the upper half of the middle shell 111 and flow upward, avoiding heat loss. The hot air can only be blown out from the air outlet of the mesh cover 110 as the fan blades 120 rotate, which is conducive to ensuring the effect of warm air; and the upper half of the middle shell 111 can also block part of the cold air from entering the mesh cover 110, thus reducing the cold air mixed in the warm air mode, and further making the fan 10 have a better warm air effect. It can be seen that the fan 10 of the present application has a good cold air effect and a good warm air effect, that is, the fan 10 of the present application can be well compatible with the cold air mode and the warm air mode.

[0113] In one embodiment, the projection of the air inlet 112 in the up-down direction falls on the base 220 and / or the humidifying device 300 and is spaced apart from the support member 210. In this way, when air enters the mesh cover 110 from the air inlet 112 at the lower half of the mesh cover 110, the support member 210 will not block the air, which is conducive to the air entering the mesh cover 110 smoothly from the air inlet 112.

[0114] In one embodiment, the mesh cover 110 has an air inlet end and an air outlet end opposite to each other, the air inlet 112 is disposed between the air inlet end and the air outlet end, and at least part of the projection of the fan blades 120 in the up and down directions falls into the air inlet 112 .

[0115] It is understandable that the air inlet 112 is arranged between the air inlet end and the air outlet end. In the cold air mode, in addition to the cold air entering from the air inlet end of the mesh cover 110, the cold air can also enter from the air inlet 112, so that the cold air intake can be supplemented to ensure the cold air outlet, so that the fan 10 has a better cold air effect. Moreover, in the heating mode, the cold air mainly enters from the air inlet end, and the air entering the air inlet end is heated by the heating element 400 and then discharged. In the heating mode, the speed of the fan blade 120 is reduced, and the air entering the air inlet 112 is less, and the upper half of the middle shell 111 is closed, which further reduces the entry of cold air from the side of the mesh cover 110, that is, reduces the cold air mixed in the warm air, so that the cold air in the warm air blown out from the air outlet end of the mesh cover 110 is less, and the fan 10 has a better warm air effect.

[0116] Furthermore, at least part of the projection of the fan blades 120 in the up-down direction falls into the air inlet 112, so that the air entering from the air inlet 112 will be directly dispersed by the rotating fan blades 120, thereby reducing the wind resistance of this part of the air and reducing the noise generated by the reversal of this part of the air. It can be seen that this solution is conducive to reducing the noise generated by the fan 10 while increasing the air intake volume by setting the downward projection of at least part of the fan blades 120 to fall into the air inlet 112, thereby improving the applicability of the fan 10.

[0117] In one embodiment, the projection of one end of the fan blade 120 close to the heating element 400 in the vertical direction falls into the air inlet 112. With such a configuration, all the air entering from the air inlet 112 can be dispersed by the rotating fan blade 120 and then blown out from the air outlet end of the mesh cover 110, further reducing the wind resistance of the air entering from the air inlet 112 and reducing the noise generated by the reversal of this part of the air.

[0118] In one embodiment, the projection of one end of the heating element 400 away from the fan blade 120 in the vertical direction falls outside the air inlet 112. This arrangement prevents the air entering from the air inlet 112 from directly blowing toward the heating element 400 and generating noise.

[0119] See also Fig.15 In order to ensure that the fan 10 has a better warm air effect, in one implementation, the spacing between the heating element 400 and the fan blade 120 in the axial direction of the fan blade 120 is D2, wherein 10mm≤D2≤25mm. It is understandable that when the distance between the heating element 400 and the fan blade 120 is close, the high temperature generated by the heating element 400 will cause the fan blade 120 to deform; when the distance between the heating element 400 and the fan blade 120 is far, it will affect the warm air effect of the fan 10. This solution limits the spacing between the heating element 400 and the fan blade 120 along the axial direction of the fan blade 120, so that the fan 10 has a better warm air effect, wherein D2 can be 10mm, or 12mm, or 15mm, or 18mm, or 20mm, or 22mm, or 25mm, etc., which is not specifically limited here.

[0120] See also Fig.15 In order to reduce the noise of the fan 10, in one embodiment, the air inlet 112 has a first edge away from the air inlet end, and the distance between the end of the fan blade 120 close to the heat generating element 400 and the first edge in the axial direction of the fan blade 120 is D3, and the height of the fan blade 120 along its axial direction is H, wherein 5mm≤D3≤H.

[0121] It is understandable that by limiting the size of D3, it is possible to ensure that the downward projection of part of the fan blades 120 or all of the fan blades 120 falls into the air inlet 112. According to the above, the air entering along the radial direction of the fan blades 120 and through the air inlet 112 can be dispersed by the rotating fan blades 120 and then blown out from the air outlet end of the mesh cover 110, which can reduce the wind resistance of the air entering from the air inlet 112, thereby reducing the noise generated by the reversal of this part of the air. Among them, D3 can be 5mm, or 8mm, or 10mm, or 15mm, etc., and can be specifically set according to the height H of the fan blades 120 along its axial direction, which is not limited here.

[0122] In one embodiment, at least a portion of the projection of the fan blade 120 in the up and down direction falls on the humidifying device 300, the mist outlet 310 is opened upward and is located on the air outlet side of the heating element 400 along the axial direction of the fan blade 120, and the projection of the air inlet 112 in the up and down direction falls outside the mist outlet 310 and is located between the mist outlet 310 and the air inlet end of the mesh cover 110. In such an arrangement, the fan blade 120 is located directly above the humidifying device 300, and along the axial direction of the fan blade 120, the mist outlet 310 is located downstream of the heating element 400, and the air inlet 112 is located between the mist outlet 310 and the air inlet end of the mesh cover 110. When the mist outlet 310 sprays water mist outward, the water mist will flow upward and flow forward along the air outlet end of the mesh cover 110. The water mist will not enter the mesh cover 110 along the air inlet 112 to cause the heating element 400 to fail. In this way, the influence of the water mist on the heating element 400 is avoided, and the service life of the fan 10 is improved.

[0123] See also Figure 4 In order to prevent water mist from entering the mesh cover 110 and causing the heating element 400 to fail, in one embodiment, on the axial projection surface of the fan blade 120, the mist outlet 310 has a second edge close to the air inlet end of the mesh cover 110, and the second edge and the first edge of the air inlet 112 away from the air inlet end of the mesh cover 110 in the axial direction of the fan blade 120 are spaced D4, wherein D4 ≥ 50 mm.

[0124] It can be understood that, along the axial direction of the fan blade 120, the second edge of the mist outlet 310 is located downstream of the first edge of the air inlet 112, and the distance between the second edge and the first edge is D4. By limiting D4 to be not less than 50 mm, it is ensured that the water mist will flow toward the air outlet end of the mesh cover 110 when sprayed upward, and the water mist will not enter the mesh cover 110 to affect the heating element 400. Among them, D4 can be 50 mm, or 55 mm, or 60 mm, or 70 mm, etc., which is not specifically limited here.

[0125] See also Fig.12 , Fig.13 , Fig.16 and Fig.17 In one embodiment, the fan 10 further includes a filter 700 , which is detachably mounted on the mesh cover 110 and located outside the mesh cover 110 , so as to filter the air inhaled and / or blown out by the fan blades 120 .

[0126] It is understandable that the filter element 700 is disposed outside the mesh cover 110 and is detachably connected to the mesh cover 110. There are various ways of detachable connection, such as but not limited to: snap connection, or screw connection, which can be specifically set as needed.

The mesh cover 110 has an air inlet end and an air outlet end. When the fan blades 120 rotate, air is sucked in from the air inlet end of the mesh cover 110, passes through the air flow channel of the mesh cover 110, and is discharged from the air outlet end of the mesh cover 110.

[0129] Furthermore, the driving member 130 is disposed in the mesh cover 110, and the driving member 130 occupies a certain space in the mesh cover 110. The driving member 130 in this solution passes through the air inlet side of the mesh cover 110 to the outside of the mesh cover 110, thereby reducing the space occupied by the driving member 130 in the mesh cover 110 and utilizing the space outside the mesh cover 110. This is beneficial to improving the space utilization rate inside and outside the mesh cover 110, is beneficial to the miniaturization of the mesh cover 110, and is also beneficial to the heat dissipation of the driving member 130.

[0130] In one embodiment, the filter element 700 is located on the air inlet side, and a evacuation portion for evading the driver 130 is provided on the filter element 700. It is understandable that the filter element 700 is provided outside the mesh cover 110 and is located on the air inlet side of the mesh cover 110, and one end of the driver 130 facing the air inlet side passes out of the mesh cover 110. In order to avoid interference between the filter element 700 provided on the mesh cover 110 and the part of the driver 130 passing out, a evacuation portion is provided on the filter element 700, and the evacuation portion can be hole-shaped, or groove-shaped, or other shapes, which are not limited here. By providing the evacuation portion, the driver 130 can pass smoothly out of the mesh cover 110, and the arrangement structure of the filter element 700 provided outside the mesh cover 110 and the driver 130 is compact, and the integrity of the fan 10 is better.

The filter screen 710 is disposed outside the mesh cover 110 and located on the air inlet side. The driving element 130 located outside the mesh cover 110 is disposed in the avoidance hole 711 .

[0132] It is understandable that the filter 710 can be made of a variety of materials, such as a polyester screen, a fiber screen, or a nylon screen, etc., which are not specifically limited here. The avoidance hole 711 can be set in the middle of the filter 710, or any other position. In this embodiment, the center line of the avoidance hole 711 coincides with the center line of the filter 710, and the filter 710 is sleeved on the drive member 130 located outside the mesh cover 110 through the avoidance hole 711. In this way, the space on the air inlet side of the mesh cover 110 is fully utilized, and the filter 710 and the drive member 130 do not interfere with each other. The two structures are compactly arranged, and the overall space utilization rate of the fan 10 is high, which is conducive to the miniaturization of the fan 10 and the reduction of material consumption, thereby helping to reduce production costs.

[0134] It can be understood that the filter cover 720 is provided with air holes, and the air holes are arranged corresponding to the filter screen 710. When the fan blades 120 rotate, the air inhaled by the fan blades 120 passes through the air holes and the filter screen 710 in sequence and enters the mesh cover 110, and flows along the air flow channel of the mesh cover 110 and is discharged from the air outlet side of the mesh cover 110. The air holes are used for air to pass through.

[0135] Furthermore, the filter cover 720 is also provided with an avoidance groove for accommodating the end of the driving member 130 that passes through the mesh cover 110. By providing the avoidance groove, the end of the driving member 130 can be covered in the filter cover 720.

In the present embodiment, the limiting portion includes a plurality of limiting blocks, which are arranged in sequence and spaced apart on the groove side wall of the groove around the circumference of the filter cover 720 to form a limiting groove with the groove. The filter element 700 is arranged in the limiting groove, and the limiting block limits the filter screen 710 to prevent the filter screen 710 from falling out of the limiting groove, so that the filter screen 710 can be stably installed in the filter cover 720, and the filter screen 710 is easy to install and replace in the filter cover 720.

[0138] In one embodiment, the filter cover 720 is detachably connected to the mesh cover 110. It is understandable that there are many ways of detachable connection, such as snap connection, or connection through a connector. In this embodiment, a groove is provided on the outer surface of the mesh cover 110 facing the air inlet side, and the filter element 700 is arranged in the groove. Such a configuration facilitates the installation of the filter element 700.

[0139] In one embodiment, a buckle is provided on one of the filter cover 720 and the mesh cover 110, and a slot is provided on the other, and the buckle is engaged with the slot. It is understandable that the buckle can be a rotary buckle, and the slot is adapted to the rotary buckle. When installing the filter cover 720, the rotary buckle can be locked in the slot by rotating the filter cover 720. In this embodiment, a rotary buckle is provided on the outer peripheral wall of the filter cover 720, and a slot is provided on the side wall of the groove, so that the filter cover 720 is easily installed in the groove of the mesh cover 110.

[0140] In one embodiment, a first screw hole is provided on the filter cover 720, and a second screw hole is provided on the mesh cover 110. The filter cover 720 and the mesh cover 110 are fixed together by screws passing through the first screw hole and the second screw hole in sequence, thereby ensuring the stability of the filter cover 720 installed on the mesh cover 110.

[0141] See also Fig.16 and Fig.17In one embodiment, the filter cover 720 is further provided with a first heat dissipation hole 721 , the driving member 130 is provided with a second heat dissipation hole 131 , and the first heat dissipation hole 721 is connected to the second heat dissipation hole 131 .

[0142] It can be understood that the first heat dissipation hole 721 is arranged outside the mesh cover 110, the driving member 130 includes a shell, the driving motor is arranged in the shell, and the shell is provided with a second heat dissipation hole 131 connected with the first heat dissipation hole 721. The air outside the filter cover 720 can pass through the first heat dissipation hole 721 and the second heat dissipation hole 131 into the shell to dissipate the heat of the driving motor. Of course, the shell is also provided with a third heat dissipation hole for air to be discharged outside the shell, which can improve the heat dissipation effect of the driving motor and improve the stability of the operation of the fan 10.

[0143] In addition, the third heat dissipation hole is arranged in the mesh cover 110, that is, the air dissipated by the driving motor will be discharged into the mesh cover 110. When the heating element 400 of the fan 10 is working, the hot air blown out by the driving motor for heat dissipation merges with the air heated by the heating element 400 and is blown out from the exhaust side of the mesh cover 110, which is beneficial to improving the heating effect of the fan 10.

[0144] See also Fig.18 and Fig.19 In one embodiment, the fan 10 further includes a clean ion generator 800 , and the clean ion generator 800 is disposed in the mesh cover 110 to generate clean ions in the mesh cover 110 .

[0145] It can be understood that the net ion generator 800 is used to generate net ions, which are positive and negative ion groups. The positive ions combined with negative ions can surround and decompose harmful substances such as floating molds and viruses in the air. The ions in the ion group generate the most oxidizing OH- (hydroxyl) free radicals at the moment of attaching to the surface of the floating bacteria, extracting H+ (hydrogen ions) from the protein of the floating bacteria, making them inactive, causing the floating bacteria to die, and returning the H2O generated by the combination of OH- and H+ to the air in the form of water molecules, thereby achieving the purpose of purifying the air; and the net ions can also inhibit the proliferation and reproduction of the attached mold, and further eliminate odors and odors. In addition, the net ion generator 800 can be set on the mesh cover 110, and of course it can also be fixed by a mounting bracket. The specific position is not limited, as long as the net ions generated by the net ion generator 800 can flow with the air in the airflow channel.

[0146] It can be seen that the clean ion generator 800 in the present solution can generate clean ions, which are discharged into the room along with the air in the air flow channel of the mesh cover 110 to sterilize the indoor air. It can also inhibit the growth of bacteria in the air and achieve the effect of removing odors. That is, the fan 10 in the present solution also has the function of sterilizing the air and removing odors, and the fan 10 of the present application is highly practical.

[0147] In one embodiment, the fan 10 further includes a heat insulating member 600, which is disposed in the mesh cover 110 and is sleeved outside the heating member 400 along the axial direction of the fan blade 120; the net ion generator 800 is disposed on the mesh cover 110 and / or the heat insulating member 600, and the net ion generator 800 is spaced apart from the heating member 400.

[0148] It is understandable that the heat insulating member 600 can be arranged in a ring shape, and the heat insulating member 600 is used to isolate the heat of the heating element 400 to prevent the heat of the heating element 400 from being transferred to the mesh cover 110. In one embodiment, the fan 10 further includes a driving member 130, and the driving member 130 is installed on the heat insulating member 600. Among them, the driving member 130 can be a driving motor, that is, the driving motor is installed on the heat insulating member 600, so that the structure inside the mesh cover 110 is compactly arranged, the utilization rate of the heat insulating member 600 is high, and no additional fasteners are required, which is conducive to the miniaturization of the fan 10 and the reduction of material consumption, thereby helping to reduce the production cost of the fan 10.

[0149] Furthermore, the clean ion generator 800 can be arranged on the mesh cover 110, or on the heat insulating member 600. Of course, a part of it can be arranged on the mesh cover 110, and the other part can be arranged on the heat insulating member 600. It can be arranged specifically as needed and is not limited here. When the clean ion generator 800 is arranged on the heat insulating member 600, the structure of the heat insulating member 600 and the clean ion generator 800 is compactly arranged, and the utilization rate of the heat insulating member 600 is high. The clean ion generator 800 is arranged at a distance from the heating element 400 to prevent the heat generated by the heating element 400 from scalding or burning the clean ion generator 800, thereby increasing the service life of the clean ion generator 800.

[0150] In one embodiment, the heat insulating member 600 and the mesh cover 110 enclose a receiving cavity, the clean ion generator 800 is disposed in the receiving cavity, and the clean ion generator 800 includes a clean ion emission head 810, and the clean ion emission head 810 passes through the receiving cavity toward the heating element 400.

[0151] It can be understood that the clean ion generator 800 is arranged in a accommodating cavity formed by the thermal insulation member 600 and the mesh cover 110. The accommodating cavity is not only used for the installation of the clean ion generator 800, but also can shield the clean ion generator 800. In this way, the thermal insulation member 600 can protect the clean ion generator 800 and avoid the clean ion generator 800 from being fully exposed in the mesh cover 110, thereby improving the aesthetics of the fan 10.

[0152] Furthermore, the net ion emission head 810 has a net ion emission port 811, which passes through the heating element 400 to the outside of the accommodating cavity and is spaced apart from the heating element 400. This facilitates the emission of the net ions generated by the net ion emission head 810 to the outside of the accommodating cavity. That is, the net ions generated by the net ion emission head 810 can be directly emitted into the air flow channel and flow into the room with the air, so as to realize the function of sterilizing and removing odors from the indoor air by the net ions.

[0153] See also Fig.19 In one embodiment, the net ion generator 800 also includes a generator body 820 connected to the net ion emission head 810, the generator body 820 is disposed in the accommodating cavity, the mesh cover 110 and / or the thermal insulation member 600 are provided with a mounting hole connected to the accommodating cavity, and the net ion emission head 810 is passed through the mounting hole.

[0154] It is understandable that the generator body 820 is electrically connected to the controller of the fan 10, and the controller supplies power to the generator body 820 so that the generator body 820 is ionized to generate clean ions, and the generated clean ions are emitted through the clean ion emission head 810. The mounting hole is provided on the mesh cover 110; or, the mounting hole is provided on the heat insulating member 600; or, the mesh cover 110 and the heat insulating member 600 are enclosed to form a mounting hole, and the heating element 400 is spaced apart from the mounting hole. The clean ion emission head 810 is inserted into the mounting hole, and a clean ion emission port 811 is provided at one end of the clean ion emission head 810 close to the heating element 400, and the clean ion emission port 811 is provided between the mounting hole and the heating element 400. With such a configuration, when the heating element 400 is working, the clean ions emitted from the clean ion emission port 811 can also be heated, which is beneficial to improve the sterilization effect of the clean ions.

[0155] See also Fig.18 In one embodiment, the thermal insulation member 600 includes a thermal insulation ring 610 and a cover body 620, the thermal insulation ring 610 is sleeved on the outside of the heating element 400, the net ion generator 800 is arranged on the mesh cover 110, the cover body 620 is arranged on the outer peripheral wall of the thermal insulation ring 610 and covers the net ion generator 800, and the cover body 620 and the mesh cover 110 enclose the mounting hole.

[0156] It is understandable that a mounting position may be provided on the mesh cover 110, and both the generator body 820 and the net ion emission head 810 may be provided in the mounting position, and the cover body 620 covers the generator body 820 and the net ion emission head 810 to fix and protect the generator body 820 and the net ion emission head 810; and the mounting hole is formed by the cover body 620 and the mesh cover 110, so that the net ion emission head 810 is conveniently inserted into the mounting hole, and the net ion emission port 811 of the net ion emission head 810 is easy to pass out of the mounting hole. It can be seen that this solution enables the net ion generator 800 to be stably installed in the mesh cover 110, and avoids the heat generated by the heating element 400 from burning the net ion generator 800, thereby improving the reliability of the fan 10.

[0157] In one embodiment, the net ion emission head 810 has a net ion emission port 811, which is spaced apart from the heating element 400 and is arranged between the inner circumferential wall of the insulation ring 610 and the heating element 400 along the radial direction of the insulation ring 610.

[0158] It can be understood that the opening direction of the net ion emission port 811 can be set toward the heating element 400, and the heating element 400 is arranged in the air flow channel of the mesh cover 110, so that the net ions emitted from the net ion emission port 811 can be smoothly discharged into the room along the air flow channel; and, the net ion emission port 811 is arranged between the inner wall of the insulation ring 610 and the heating element 400 along the radial direction of the insulation ring 610, and the annular structure of the insulation ring 610 forms an air guide channel, that is, the net ion emission port 811 is arranged on the outer peripheral side of the heating element 400 and is located in the air guide channel of the insulation ring 610, so that the internal space of the insulation ring 610 is fully utilized, the internal space utilization rate of the insulation ring 610 is high, and it is beneficial to improve the smoothness of the flow of net ions in the air guide channel.

[0159] In one embodiment, the mesh cover 110 is rotatably disposed on the support member 210, and the rotation axis of the mesh cover 110 is disposed in the horizontal direction; and / or, the support member 210 is rotatably disposed on the base 220, and the rotation axis of the support member 210 is disposed in the vertical direction. It can be understood that the rotation axis of the mesh cover 110 is disposed in the horizontal direction, so that the fan can be set to shake its head up and down; the rotation axis of the support member 210 is disposed in the vertical direction, so that the fan can be set to shake its head left and right. In this way, the fan 10 can achieve the function of shaking its head up and down and left and right. As for the specific structure of the up and down shaking drive mechanism and the left and right shaking drive mechanism, reference can be made to the aforementioned content and no limitation is made here.

[0160] See also Figure 1 and Figure 2In one embodiment, the support member 210 includes a column rod section 211, a column inclined section 212 and a column bracket 213 with an opening, the column inclined section 212 is connected to the upper end of the column rod section 211 and tilted upward, the column bracket 213 is connected to the column inclined section 212, and the mesh cover 110 is arranged at the opening and is rotatably connected to the opposite ends of the column bracket 213.

[0161] It can be understood that the column inclined section 212 is inclined upward, that is, an angle is formed between the column rod section 211 and the column inclined section 212. By setting the angle, the column bracket 213 can also be inclined, so that the position of the mesh cover 110 can be adjusted so that the downward projection of the air inlet 112 in the lower half of the mesh cover 110 falls on the base 220 and is spaced apart from the support member 210, thereby improving the smoothness of air entering the mesh cover 110 along the air inlet 112.

[0162] Furthermore, the column bracket 213 is arranged in a U shape, and the mesh cover 110 is rotatably arranged on the U-shaped column bracket 213. The rotation axis of the mesh cover 110 is arranged in the horizontal direction and passes through the column bracket 213, so that the mesh cover 110 can be set to shake up and down relative to the column bracket 213.

[0163] See also Figure 2 In one embodiment, the column rod segment 211 is arranged along the vertical direction, and the angle between the column inclined section 212 and the column rod segment 211 is α, wherein 105°≤α≤150°; and / or, the opening of the column bracket 213 is arranged upward, and on the axial projection plane of the fan blade 120, the angle between the column inclined section 212 and the column bracket 213 is β, wherein 60°≤β≤105°.

[0164] It can be understood that the angle between the column inclined section 212 and the column rod section 211 can be 105°, or 110°, or 120°, or 130°, or 140°, or 150°, etc., and is not specifically limited here. By limiting the size of α, it is ensured that the column inclined section 212 can be tilted upward, which is beneficial for the downward projection of the air inlet 112 of the lower half of the mesh cover 110 to fall on the base 220 and be spaced apart from the support member 210.

[0165] On the axial projection surface of the fan blade 120, the angle between the column inclined section 212 and the column bracket 213 can be 60°, or 70°, or 80°, or 90°, or 100°, or 105°, etc., and is not specifically limited here. By limiting the size of β, the inclination angle of the column bracket 213 relative to the column rod section 211 is limited, that is, the position of the fan head 100 relative to the column rod section 211 can be limited. The lower half of the middle shell 111 is provided with an air inlet 112, and the downward projection of the air inlet 112 falls on the base 220, so that air can smoothly enter the mesh cover 110 along the air inlet 112. At this time, the column rod section 211, the column inclined section 212 and the column bracket 213 cooperate to have a small resistance to the air, that is, the wind resistance of the air passing through the column assembly into the mesh cover 110 is reduced, which is conducive to increasing the amount of air entering the mesh cover 110. It can be seen that this solution is beneficial to increasing the air intake volume of the fan 10.

[0166] See also Figures 4 to 6 In one embodiment, the fan 10 further includes a water receiving member 900, the base 220 has a receiving chamber 221, the support member 210 is rotatably disposed on the base 220, the rotation axis of the support member 210 is arranged along the vertical direction, and a rotation gap 222 is provided between the support member 210 and the base 220, and the rotation gap 222 is communicated with the receiving chamber 221; the water receiving member 900 is disposed in the receiving chamber 221 to receive water flowing into the rotation gap 222.

[0167] It is understandable that the specific structure of the water receiving member 900 is not limited. The water receiving member 900 can be partially inserted into the rotating gap 222, and of course it can also be arranged below the rotating gap 222. It is only necessary that the water receiving member 900 can receive the water flowing into the rotating gap 222. The water in the water receiving member 900 can be collected by the water storage member, and of course it can also be discharged to the outside of the base 220 through the drainage channel 950. The specific details are not limited here, and there is a related introduction later. By providing the water receiving member 900, it is prevented that water flows into the base 220 from the rotating gap 222 and contacts the electric control components in the base 220, thereby preventing the occurrence of a short circuit in the electric control components.

[0168] See also Figure 5 In one embodiment, the base 220 includes an upper cover 223, and the upper cover 223 is provided with a first mounting hole 224 connected to the accommodating cavity 221. The support member 210 is rotatably disposed at the first mounting hole 224. The water receiving member 900 is provided with a first water receiving groove 910, and the downward projection of the edge of the first mounting hole 224 falls into the first water receiving groove 910.

[0169] It is understandable that the support member 210 can be connected to the base 220 through a left and right shaking drive mechanism, that is, the fan 10 also includes a left and right shaking drive mechanism, which is arranged at the first mounting hole 224 and is drivingly connected to the support member 210. The support member 210 can be completely arranged outside the first mounting hole 224. Of course, the support member 210 can also be inserted into the first mounting hole 224, which is not specifically limited here, and the support member 210 only needs to be rotatable relative to the base 220. The first water receiving groove 910 can be arranged in a sink shape, or in a ring groove 214 shape, which is not specifically limited here. The edge of the first mounting hole 224 is the edge of the opening of the first mounting hole 224, and the projection of the edge of the first mounting hole 224 in the up and down direction falls into the first water receiving groove 910, that is, the water flowing into the rotating gap 222 along the edge of the first mounting hole 224 can fall downward into the first water receiving groove 910, thereby realizing the function of receiving water.

[0170] See also Figure 5 In one embodiment, the edge of the first mounting hole 224 is provided with a first water retaining platform 225 extending outward, and the first water retaining platform 225 is arranged in a ring shape. It can be understood that when water falls on the base 220, if the height of the water droplets or water flow does not exceed the height of the first water retaining platform 225, the water cannot flow into the rotating gap 222, that is, the first water retaining platform 225 can block part of the water from flowing into the rotating gap 222, which is conducive to improving the safety of the fan 10.

[0171] In one embodiment, the edge of the first mounting hole 224 is provided with a second water retaining platform 226 extending inward, the second water retaining platform 226 is arranged in an annular shape, and the downward projection of the second water retaining platform 226 falls into the first water receiving groove 910. Such an arrangement enables the second water retaining platform 226 to guide the water flowing into the first water receiving groove 910 along the hole wall of the first mounting hole 224, which is conducive to all the water flowing along the inner wall of the first mounting hole 224 flowing into the first water receiving groove 910; at the same time, there is a height difference between the bottom end of the second water retaining platform 226 and the inner wall surface of the upper cover 223, and the second water retaining platform 226 can also prevent water from flowing along the edge of the first mounting hole 224 through the inner wall surface of the upper cover 223 and contacting the electric control components in the accommodating cavity 221, thereby improving the safety of the fan 10. In one embodiment, the bottom end of the second water retaining platform 226 is arranged in the first water receiving groove 910, which is conducive to improving the guiding effect of the second water retaining platform 226.

[0172] In one embodiment, the water receiving member 900 is provided with a second mounting hole 920, the lower end of the support member 210 passes through the first mounting hole 224 and the second mounting hole 920 to be rotatably connected with the base 220, and the first water receiving groove 910 is arranged in a ring shape around the second mounting hole 920. In this arrangement, the lower end of the support member 210 passes through the water receiving member 900 and is arranged in the accommodating cavity 221, and the position of the driving connection between the support member 210 and the base 220 is relatively low, which is conducive to the installation of the left and right shaking driving mechanism, and is also conducive to improving the stability of the support member 210 rotating on the base 220. The second mounting hole 920 avoids the support member 210 so that the support member 210 passes through; the first water receiving groove 910 is arranged in a ring shape around the second mounting hole 920, so that the first water receiving groove 910 can fully receive the water flowing into the rotating gap 222.
