[0058] This invention proposes a fan with multiple functions and high humidification efficiency.

[0059] Please see Figures 1 to 4In one embodiment of the present invention, the fan 10 includes a fan head 100, a support assembly 200, and a humidifying device 300. The fan head 100 includes a mesh cover 110 and fan blades 120, the fan blades 120 being rotatably disposed within the mesh cover 110. The support assembly 200 includes a support member 210 and a base 220, the fan head 100 being disposed on the support member 210, and the support member 210 being disposed on the base 220. The humidifying device 300 is disposed on the base 220 for generating water mist, the humidifying device 300 having a mist outlet 310, the mist outlet 310 being spaced apart from the fan head 100 and located below the fan head 100.

[0060] It is understood that the mesh cover 110 has an air inlet end, an air outlet end, and an airflow channel. The fan blade 120 is rotatably disposed within the airflow channel of the mesh cover 110. Air enters the mesh cover 110 from the air inlet end as the fan blade 120 rotates, and after passing through the airflow channel, it is discharged from the air outlet end of the mesh cover 110 to achieve the function of blowing cool air. The fan head 100 is disposed on the support member 210. 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 arranged in the horizontal direction.

[0061] In one embodiment, the mesh cover 110 is rotatably mounted on the support member 210, and the rotation axis of the mesh cover 110 is arranged in the horizontal direction. It is understood that the fan 10 also includes an up-and-down oscillation drive mechanism, which is connected to both the mesh cover 110 and the support member 210 to drive the mesh cover 110 to rotate relative to the support member 210. The specific structure of the up-and-down oscillation drive mechanism is not limited here. In one embodiment, the up-and-down oscillation drive mechanism includes a horizontal rotating shaft, a first drive motor, a first drive gear, and a first transmission gear. The first drive gear is sleeved on the power output shaft of the first drive motor, and the first drive gear meshes with the first transmission gear. The first transmission gear is arranged in the vertical direction. The first drive motor is installed inside the support member 210. The horizontal rotating shaft is fixedly connected to the first transmission gear. The horizontal rotating shaft is mounted on the mesh cover 110 via bearings. The mesh cover 110 is rotatably connected to the support member 210 via the horizontal rotating shaft. This configuration realizes the up-and-down oscillation function of the fan 10.

[0062] Furthermore, the support member 210 is disposed on the base 220, and the support member 210 and the base 220 can 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 arranged in the vertical direction. The fan 10 also includes a left and right oscillation drive mechanism, which is connected to the base 220 and the support member 210 respectively, to drive the support member 210 to rotate relative to the base 220. The structure of the left and right oscillation drive mechanism is not limited. In one embodiment, the left and right oscillation drive mechanism includes a vertical rotating shaft, a second drive motor, a second drive gear, and a second transmission gear. The second drive motor is installed inside the base 220. The second drive gear is sleeved on the power output shaft of the second drive motor. The second drive gear and the second transmission gear mesh. The second transmission gear is arranged in a horizontal direction. The vertical rotating shaft is fixedly connected to the second transmission gear. The vertical rotating shaft is installed inside 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 configuration, the function of the fan 10 oscillating left and right is realized.

[0063] Furthermore, the humidifier 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, or it can be set directly in front of the fan 10 or diagonally in front, so that the water mist can diffuse with the air flow and thus humidify the air.

[0064] Furthermore, the mist outlet 310 is spaced apart from the fan head 100's mesh cover 110, with the mist outlet 310 located below the mesh cover 110. The fan blades 120 rotate to drive airflow around the fan head 100. This airflow causes water mist to flow and diffuse outwards along the airflow direction of the fan 10, thus achieving the function of humidifying the air. The humidification method can be electric heating evaporation humidification or ultrasonic atomization humidification; the specific method is not limited here. In this design, no mist guide tube is provided between the mist outlet 310 and the fan head 100. This avoids the situation where water mist condenses and flows back into the mist guide tube when the humidification device 300 has a mist guide tube, affecting the humidification efficiency. The structures of the humidification device 300 and the fan head 100 are simple, and the structure between them is concise, thereby simplifying the structure of the fan 10 and making the fan 10 aesthetically pleasing.

[0065] The fan 10 of the present invention includes a fan head 100, a support assembly 200, and a humidifying device 300. The fan head 100 includes a mesh cover 110 and fan blades 120, with the fan blades 120 rotatably disposed within the mesh cover 110 to achieve the function of blowing cool air. The support 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 to support the fan head 100. The humidifying device 300 is disposed on the base 220 to generate water mist, i.e., the fan 10 of this application. The fan 10 also has the function of humidifying air. The humidifier 300 has a mist outlet 310, which is spaced apart from and 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 from the fan head 100, thereby humidifying the air. In other words, no mist guide pipe is provided between the mist outlet 310 and the fan head 100 in this design, avoiding the condensation and backflow of water mist in the mist guide pipe, which would affect the humidification efficiency. The humidifier 300 of this application has a simple structure and high humidification efficiency. Therefore, it can be seen that the fan 10 of this application, in addition to blowing cold air, also has the function of humidifying air, and the humidifier 300 has a simple structure and high humidification efficiency.

[0066] Please see Figures 1 to 4 In one embodiment, the humidification device 300 includes a housing, an atomizing plate 340, and a fan 350. The housing has an atomizing chamber 320, a mist guiding channel 330, and a mist outlet 310 connected in sequence. The atomizing plate 340 is disposed in the atomizing chamber 320 to atomize the water in the atomizing chamber 320. The fan 350 is disposed in the housing and / or the base 220, and the fan 350 is used to blow air into the atomizing chamber 320 so that the water mist in the atomizing chamber 320 is guided by the mist guiding channel 330 and discharged from the mist outlet 310.

[0067] It is understandable that the atomizing plate 340 can be an ultrasonic atomizing plate. The atomizing plate 340 is electrically connected to the controller of the fan 10. The atomizing plate 340 uses the high-frequency electronic oscillation of the ultrasonic principle to break down the liquid water molecule structure to form water mist, thus ensuring the humidification amount. At the same time, the atomizing plate 340 can be replaced in the atomizing chamber 320, which makes the structure of the humidification device 300 simple and easy to manufacture.

[0068] Furthermore, the user can add water to the atomizing chamber 320 so that the atomizing plate 340 can atomize the water into water mist. In another embodiment, the housing also 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 plate 340 can atomize the water into water mist. An air inlet can be provided on the base 220 of the fan 10 or on the housing. The fan 350 can be located at the air inlet. The number of fans 350 can be set as needed, and there is no limitation on the number.

[0069] Specifically, the controller of the fan 10 controls the operation of the atomizing plate 340 and also controls the operation of the fan 350 to blow air into the atomizing chamber 320. Water in the water storage chamber 360 flows into the atomizing chamber 320 for atomization by the atomizing plate 340. A mist passage is formed on the housing, connecting the atomizing chamber 320 and the mist guiding channel 330. When air humidification is required, the controller controls the fan 350 to rotate, blowing air into the atomizing chamber 320. Under the action of the airflow, the water mist in the atomizing chamber 320 enters the mist guiding channel 330 through the mist passage. The mist guiding channel 330 guides the airflow and water mist, so that the water mist is discharged from the mist outlet 310, and the discharged water mist humidifies the air. In this embodiment, the air inlet can be located at the bottom of the base 220 or on the side wall of the housing, and the mist outlet 310 can be located at the top of the housing. This ensures that all the water mist in the atomization chamber 320 can be discharged from the mist outlet 310 under the action of the fan 350. The mist guiding channel 330 is hidden inside the housing. Compared with the prior art that uses a mist guiding pipe to guide the water mist to the air outlet side of the mesh cover 110, the length of the mist guiding channel 330 in this solution is shorter. This avoids the situation in the prior art where the mist guiding pipe is too long, and some water mist will condense and flow back along the pipe wall, affecting the humidification efficiency. This solution is beneficial to improving the humidification effect. Furthermore, the mist guiding channel 330 improves the smoothness of water mist flow. Under the pressure of the fan 350, the water mist is sprayed outward at a faster speed, which is beneficial to improving the uniformity of the humidified air.

[0070] In one embodiment, the mist guiding channel 330 extends vertically, and the mist outlet 310 is located at the top of the housing. This arrangement reduces the resistance to water mist flow within the mist guiding channel 330, allowing the water mist to flow smoothly toward the mist outlet 310, thereby improving the smoothness of water mist flow.

[0071] In one embodiment, a mist-passing port is formed inside the housing, connecting the atomizing chamber 320 and the mist-guiding channel 330. The mist-passing port is oriented towards the side wall of the housing. Specifically, in this embodiment, the side wall of the housing is horizontal, meaning the opening of the mist-passing port is horizontal. This arrangement connects the atomizing chamber 320 and the mist-guiding channel 330, preventing the airflow from the mist-passing port from blowing directly upwards. When the airflow containing water droplets passes through the mist-passing port and enters the mist-guiding channel 330, the water droplets 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. This prevents water droplets from being blown directly out of the mist outlet 310, thereby ensuring the humidification effect of the water mist.

[0072] In one embodiment, the base 220 is provided with an air inlet, 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, thus ensuring that all the water mist in the atomizing chamber 320 can be discharged from the mist outlet 310.

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

[0074] Understandably, the water storage chamber 360 is arranged around the periphery of the mist guiding channel 330. This makes full use of the internal space of the shell, resulting in a compact arrangement of the mist guiding channel 330 and the water storage chamber 360. The mist guiding channel 330 extends vertically, and the mist outlet 310 is located at the top of the shell, allowing the water mist to flow smoothly towards the mist outlet 310. At the same time, the mist guiding channel 330 is also hidden inside the shell. Compared with the prior art that uses a mist guiding pipe to guide the water mist to the mesh cover 110, the length of the mist guiding channel 330 in this solution is shorter. This avoids the situation in the prior art where the mist guiding pipe is too long, and some water mist will condense and flow back along the pipe wall, affecting the humidification efficiency. This solution is beneficial to improving the humidification effect.

[0075] In one embodiment, the mist guiding channel 330 includes at least a gradually widening section, the inner diameter of which gradually increases from bottom to top. This arrangement facilitates the smooth upward flow of water mist and promotes its outward diffusion.

[0076] Please see Figures 7 to 12 In one embodiment, the fan 10 further includes a heating element 400, which is disposed inside the mesh cover 110 and located between the fan blade 120 and the air inlet end of the mesh cover 110, for heating the air.

[0077] It is understood that the heating element 400 is located on the air inlet side of the fan blade 120. When the fan blade 120 rotates, cold air is drawn in from the air inlet of the mesh cover 110, heated by the heating element 400, and then blown out from the air outlet of the mesh cover 110 as the fan blade 120 rotates. The hot air is dispersed by the rotation of the fan blade 120, resulting in uniform hot airflow, which helps improve user comfort. The type and shape of the heating element 400 are not limited here. The heating element 400 can be a heating wire 420, a heating tube, or other objects capable of generating heat. When the fan 10 is in warm air mode, the heating element 400 operates to heat the air flowing along the airflow channel of the mesh cover 110. The heated air is discharged from the air outlet of the mesh cover 110 as the fan blade 120 rotates, so that the fan 10 can blow out warm air, that is, the fan 10 of this application has a heating function.

[0078] Please see Figures 7 to 11 In one embodiment, the fan 10 further includes a plurality of overheat protectors 500, which are disposed inside the mesh cover 110 and electrically connected to the heating element 400 respectively, for overheat protection of the heating element 400. The plurality of overheat protectors 500 are arranged sequentially along the extension direction of the airflow 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] Understandably, multiple overheat protectors 500 are electrically connected to the heating element 400, and each of the multiple overheat protectors 500 provides overheat protection for the heating element 400. The multiple overheat protectors 500 correspond to various abnormal operating states of the heating wire 420. The multiple overheat protectors 500 are arranged sequentially along the extension direction of the airflow channel of the mesh cover 110. For example, one overheat protector 500 is located on the periphery of the heating element 400, one overheat protector 500 is located on the air outlet side of the heating element 400, or one overheat protector 500 is located on the air inlet side of the heating element 400. The specific configuration can be determined according to the needs.

[0080] If one of the overheat protectors 500 fails to detect a rapid increase in the temperature of the heating element 400 in time, another overheat protector 500 among the multiple overheat protectors 500 arranged sequentially along the extension direction of the airflow channel can detect the rapid increase in the temperature of the heating element 400 in time. In other words, the multiple overheat protectors 500 arranged sequentially along the extension direction of the airflow channel can correspond to different temperature rise states of the heating element 400, thereby being able to detect the overheating of the heating element 400 in time and thus provide overheat protection to ensure the safety of the fan 10.

[0081] It should be noted that one of the overheat protectors 500 is located on the air outlet side of the heating element 400. Here, the air outlet side refers to the downstream side of the heating element 400 when air passes through it. For example... Figure 7 In the middle, air enters the mesh cover 110 from the rear cover 114 and passes through the heating element 400 before being blown 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 and the fan blades 120 cannot rotate normally, the heating element 400 continues to work. Heat accumulates on the heating element 400. The overheat protector 500 located on the air outlet side of the heating element 400 can quickly sense the rapid rise in the temperature of the heating element 400. When the temperature exceeds the preset protection value of the overheat protector 500, the overheat protector 500 will cut off the power to the heating element 400 to prevent fires, electric shocks, and other situations caused by overheating of the heating element 400, thereby ensuring the safety 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 when the temperature is too high, and the temperature limiter is a resettable temperature controller. The fuse is used to melt its own fusible element 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. The melting temperature of the fuse is higher than the cutting-off temperature of the temperature limiter. In this case, the fuse provides double protection for the heating element 400, thereby improving the safety of the fan 10.

[0084] Therefore, multiple overheat protectors 500 are installed within the airflow channel and electrically connected to the heating element 400 respectively, to provide overheat protection for the heating element 400. When the heating element 400 is in an abnormal overheating state, the multiple overheat protectors 500 arranged sequentially along the extension direction of the airflow channel, as well as at least one overheat protector 500 on the air outlet side of the heating element 400, can promptly sense the rise in the temperature of the heating element 400 and disconnect the circuit. This prevents the heating element 400 from overheating and causing fires or electric shocks in situations such as the fan 10 tipping over or the fan blades 120 stopping. In other words, the fan 10 of this solution can prevent fires and electric shocks caused by overheating of the heating element 400, thus improving the safety of the fan 10. Therefore, in addition to its air blowing function, 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 periphery 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 a corresponding air inlet and outlet, and the fan 10 has a front and a rear. When the air outlet of the mesh cover 110 faces the front of the fan 10, that is, on the projected surface of the heating element 400, if the fan blade 120 stops rotating or rotates slowly due to a malfunction, the heating element 400 will heat up rapidly. The heat generated by the heating element 400 will flow upwards, and the first overheat protection device located around the heating element 400 can promptly and sensitively sense the temperature rise of the heating element 400, thereby quickly cutting off the power to the heating element 400. In this way, the first overheat protector 510 can provide overheat protection for the heating element 400. The first overheat protector 510 is located around the upper half of the heating element 400, which further improves the sensing sensitivity of the first overheat protection device.

[0087] Furthermore, when the fan 10 tilts, the air outlet of the mesh cover 110 faces upward or downward at an angle, i.e., the air outlet of the mesh cover 110 is at an upward or downward angle. The heating element 400 is also tilted. The second overheat protector 520 is located on the air outlet side of the heating element 400. When the fan blade 120 stops rotating or rotates slowly due to a malfunction, the heating element 400 heats up rapidly. The heat generated by the heating element 400 will flow upward. At this time, the second overheat protector 520 is closer to the heating element 400, and the hot airflow will pass through the second overheat protector 520. In this way, the second overheat 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. Therefore, when the fan 10 tilts, the second overheat protector 520 is located on the air outlet side of the heat-generating element 400 and can promptly and sensitively protect the heat-generating element 400 from overheating. This solution, through the cooperation of the first overheat protector 510 and the second overheat protector 520, ensures the safety of the fan 10 in use.

[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 is understood that the interval arrangement of the first overheat protector 510 and the second overheat protector 520 along the extension direction of the airflow channel ensures that the temperatures on the first overheat protector 510 and the second overheat protector 520 do not interfere with each other, which is beneficial 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 ensures sufficient spacing between them but also allows them to be at 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 protectors 510 and the second overheat protector 520 is closer to the heating element 400, it can promptly and sensitively sense the temperature rise of the heating element 400, thereby quickly cutting off the power to the heating element 400 and improving the safety of the fan 10.

[0090] Please see 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 around the outer peripheral wall of the heating bracket 410 and forms a receiving notch 430 with the heating bracket 410. The first overheat protector 510 is disposed on the heating bracket 410 and located in the receiving notch 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 turn, two turns, or more turns. In this embodiment, the number of heating wires 420 is two turns. By providing a receiving notch 430 on the heating element 400 for the installation of the first overheat protector 510, the structure of the heating element 400 is fully utilized, without the need to reserve space for the first overheat protector 510 inside the mesh cover 110, thus improving the space utilization rate inside the mesh cover 110. Furthermore, the first overheat protector 510 is located within the receiving notch 430, making the distance between the first overheat protector 510 and the heating wire 420 relatively close. The first overheat protector 510 can quickly sense the temperature rise of the heating wire 420, which helps to improve the sensing sensitivity of the first overheat protector 510. Furthermore, since the receiving notch 430 is located on the periphery of the upper half of the heating element 400, that is, when the first overheat protector 510 is located on the periphery of the upper half of the heating element 400, if the fan blade 120 stops rotating or rotates slowly due to a malfunction, the heating element 400 will heat up rapidly. The heat generated by the heating wire 420 will flow upward and pass through the first overheat protector 510, thereby enabling the first overheat protector 510 to accurately and sensitively sense the temperature rise change, and thus enabling the first overheat protector 510 to quickly cut off the power to the heating wire 420. Therefore, this solution is beneficial 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 located 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 this arrangement, when the fan 10 tilts and the heating wire 420 tilts, the second overheat protector 520, located outside the receiving notch 430 and downstream of the first overheat protector 510, is relatively close. Simultaneously, the offset arrangement of the second overheat protector 520 from the first overheat protector 510 allows the second overheat protector 520 to quickly and sensitively sense changes in the temperature rise of the heating wire 420, enabling it to quickly cut off power to the heating wire 420. This improves the reliability of the second overheat protector 520 and also enhances the safety of the fan 10.

[0093] Furthermore, the second overheat protector 520 is located downstream of the upper half of the heating element 400. This arrangement ensures that when the fan blade 120 stops rotating due to a malfunction or rotates slowly, the heating element 400 heats up rapidly. The heat generated by the heating wire 420 flows upwards and passes through the second overheat protector 520, allowing it to accurately and sensitively detect the temperature change and cut off power to the heating wire 420. Therefore, this design improves the safety of the fan 10.

[0094] To improve the accuracy and sensitivity of the temperature sensing of the first overheat protector 510, please refer to [link / reference needed]. Figure 11 In one embodiment, on the orthographic projection plane of the heating element 400, the angle between the line connecting the center line of 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 is understandable that, on the projected 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, and the line on the horizontal plane is L2. 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 limited. Limiting the position of the first overheat protector 510 helps to improve the sensitivity of temperature sensing and to quickly and accurately sense changes in temperature rise, thereby quickly cutting off power to the heating wire 420. The angle M can be 25°, 30°, 40°, 45°, 50°, 60°, or 65°, etc., specifically limited here.

[0096] In one embodiment, the mesh cover 110 has opposing air inlet and air outlet ends. 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 disposed above a line parallel to the horizontal plane and passing through the center line of the heating element 400.

[0097] With this configuration, when the air outlet faces the front of the fan 10, the first overheat protector 510 and / or the second overheat protector 520 are located above L2, that is, the first overheat protector 510 is located on the periphery of the upper half of the heating element 400, and / or the second overheat protector 520 is located on the air outlet side of the upper half of the heating element 400. As mentioned above, when the heating element 400 overheats and the fan 10 is facing forward, 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. When the fan 10 is tilted 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 work together to ensure the safety of the fan 10.

[0098] Please see Figure 9 and Figure 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 is understandable 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 limit the protection of 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 temperature controller.

[0100] Furthermore, the second temperature limiter 521 is used to automatically cut off the power when the temperature is too high. The second temperature limiter 521 is a resettable temperature controller. 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. This setting allows the second temperature limiter 521 to provide limit protection for the heating element 400 independently. The second temperature limiter 521 and the first temperature limiter 511 do not interfere with each other. This can correspond to different temperature rise states of the heating element 400, thereby improving the safety of the fan 10 when using the heating function.

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

[0102] Understandably, the first fuse 512 is used to melt its own fusible element when the temperature is too high. The first fuse 512 is connected in series in the first circuit and 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, thus improving the reliability of the first overheat protector 510.

[0103] Similarly, the second fuse 522 is used to melt its own fusible element when the temperature is too high. The second fuse 522 is connected in series in the second circuit and in parallel with the first circuit. That is, the second fuse 522 and the second temperature limiter 521 can provide dual protection for the heating element 400, thus providing double insurance for the heating element 400, thereby 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℃ to 100℃; and / or, the temperature limit protection range of the second temperature limiter 521 is 70℃ to 130℃. This configuration provides overheat protection for the heating element 400, preventing fires, electric shocks, and other accidents caused by overheating, 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. This configuration further provides overheat protection for the heating element 400. It is understood 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 provides overheat protection for the heating element 400, and when the first temperature limiter 511 fails, the first fuse 512 then provides overheat protection for the heating element 400, thus providing double protection 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 provides overheat protection for the heating element 400. When the second temperature limiter 521 fails, the second fuse 522 then provides overheat protection for the heating element 400, which is a double insurance for the heating element 400.

[0106] Please see Figure 7 , Figure 12 and Figure 13 In one embodiment, the fan 10 further includes a heat insulation member 600, which is disposed inside the mesh cover 110 and sleeved around the heat-generating member 400 along the axial direction of the fan blade 120.

[0107] It is understandable that the heat insulation component 600 can be arranged in a ring shape. The heat insulation component 600 is used to insulate against heat generated by the fan, preventing heat from the heat-generating component 400 from being transferred to the grille 110. Especially when the fan blade 120 stops rotating due to a malfunction, or when the fan blade 120 speed decreases and the fan 10 malfunctions, if the heat insulation component 600 is not installed, the heat from the heat-generating component 400 will be transferred to the grille 110 or objects outside the grille 110, potentially causing fires or other safety accidents. This solution, by sleeved around the heat-generating component 400 along the axial direction of the fan blade 120, improves the safety performance of the fan 10. In this embodiment, the centerline of the heat insulation component 600 coincides with the rotation axis of the fan blade 120, which helps improve the consistency of the fan 10.

[0108] In addition, the heat insulation component 600 also has the function of concentrating heat. When the heating element 400 heats the air, the heat generated by the heating element 400 is concentrated within the heat insulation component 600 to prevent the heat from dissipating arbitrarily. The rotation of the fan blades 120 carries away the concentrated heat, thus improving the heating effect of the fan 10. Furthermore, by setting the heat insulation component 600, the heat on the mesh cover 110 is lower, allowing the mesh cover 110 to be made of a material with lower heat resistance than the heat insulation component 600. Since the material usage of the mesh cover 110 is greater than that of the heat insulation component 600, using a material with lower heat resistance in the mesh cover 110 helps reduce the manufacturing cost of the fan 10.

[0109] Please see Figure 14 and Figure 15 In one embodiment, the distance between the heating element 400 and the heat insulation element 600 in the radial direction of the fan blade 120 is D1, where 5mm ≤ D1 ≤ 25mm. It is understood that when the distance between the heating element 400 and the heat insulation element 600 is too close, the heat insulation element 600 will affect the smoothness of airflow; when the distance between the heating element 400 and the fan blade 120 is too far, it will affect the heat insulation and heat concentration effect of the fan 10. This solution limits the distance between the heating element 400 and the heat insulation element 600 in the radial direction of the fan blade 120, allowing air to flow smoothly within the heat insulation element 600 and achieving a better heat insulation effect. D1 can be 5mm, 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, or 25mm, etc., and is not specifically limited here.

[0110] Please see Figure 4 , Figure 7 , Figure 14 and Figure 15 In one embodiment, the mesh cover 110 has a ring-shaped middle shell portion 111, the upper half of the middle shell portion 111 is closed, and the lower half of the middle shell portion 111 is provided with an air inlet 112.

[0111] It is understood that the mesh cover 110 may include a front cover 113 and a rear cover 114, with the front cover 113 and the rear cover 114 detachably connected. In this case, the middle shell portion 111 is a part of either 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, with the front cover 113 and the middle shell detachably connected, and the middle shell and the rear cover 114 detachably connected. The middle shell includes a middle shell portion 111. That is to say, the specific structure of the mesh cover 110 is not limited, as long as the middle shell portion 111 is 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 the air outlet, and the side of the rear cover 114 facing away from the front cover 113 is the air inlet. The middle shell is disposed between the front cover 113 and the rear cover 114. The middle shell includes a middle shell portion 111. The upper half of the middle shell is closed, and the lower half of the middle shell is provided with an air inlet 112. The air inlet 112 includes multiple air inlet holes, which are arranged sequentially on the side wall of the lower half of the middle shell to form the air inlet 112.

[0112] Furthermore, by providing an air inlet 112 in the lower half of the middle shell 111, when the fan 10 is in 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 in the lower half of the middle shell 111. This dual air intake at both the air inlet end of the mesh cover 110 and the air inlet 112 helps increase the volume of cold air intake and ensures the airflow speed, thus giving the fan 10 a better cooling effect. When the fan 10 is in warm air mode, the air entering the mesh cover 110 is heated. Hot air has a lower density and is heavier. The air is light and rises upwards. Because the upper half of the middle shell 111 is closed, the hot air inside the mesh cover 110 cannot directly pass through the upper half of the middle shell 111 and flow upwards, 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 helps to ensure the effect of warm air. In addition, the upper half of the middle shell 111 can also block some cold air from entering the mesh cover 110, thus reducing the cold air mixed in during the warm air mode, further improving the warm air effect of the fan 10. Therefore, the fan 10 of this application has good cold air and warm air effects, that is, the fan 10 of this application can be well compatible with both cold air and warm air modes.

[0113] In one embodiment, the vertical projection of the air inlet 112 falls on the base 220 and / or the humidification device 300 and is spaced apart from the support member 210. This arrangement ensures that when air enters the mesh cover 110 from the air inlet 112 in the lower half of the mesh cover 110, the support member 210 will not obstruct the airflow, facilitating smooth airflow from the air inlet 112 into the mesh cover 110.

[0114] In one embodiment, the mesh cover 110 has an air inlet end and an air outlet end, and the air inlet 112 is disposed between the air inlet end and the air outlet end, with at least a portion of the fan blades 120 projecting into the air inlet 112 in the vertical direction.

[0115] Understandably, the air inlet 112 is located between the air intake and air outlet. In cold air mode, cold air can enter from both the air intake end of the grille 110 and the air inlet 112, thus supplementing the intake volume of cold air and ensuring the output volume of cold air, thereby giving the fan 10 a better cooling effect. Moreover, in heating mode, cold air mainly enters from the air intake end. The air entering from the air intake end is heated by the heating element 400 before being discharged. In heating mode, the fan blade 120 speed is reduced, less air enters from the air inlet 112, and the upper half of the middle shell 111 is closed, further reducing the entry of cold air from the side of the grille 110, that is, reducing the amount of cold air mixed in with the warm air, so that there is less cold air in the warm air blown out from the air outlet end of the grille 110, and the fan 10 has a better warm air effect.

[0116] Furthermore, at least a portion of the fan blades 120 are projected vertically into the air inlet 112, so that the air entering from the air inlet 112 is directly dispersed by the rotating fan blades 120, thereby reducing the wind resistance of this air and reducing the noise generated by the reversal of this air. Therefore, this solution, by setting at least a portion of the fan blades 120 to have their downward projection fall into the air inlet 112, helps to increase the air intake while reducing the noise generated by the fan 10, thus improving the applicability of the fan 10.

[0117] In one embodiment, the vertical projection of the end of the fan blade 120 near the heating element 400 falls into the air inlet 112. This arrangement ensures that all the air entering from the air inlet 112 is dispersed by the rotating fan blade 120 before being blown out from the air outlet 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 this air reversal.

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

[0119] Please see Figure 15 To ensure a good heating effect for the fan 10, in one embodiment, the distance between the heating element 400 and the fan blade 120 in the axial direction of the fan blade 120 is D2, where 10mm ≤ D2 ≤ 25mm. It is understood that when the distance between the heating element 400 and the fan blade 120 is too 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 too far, it will affect the heating effect of the fan 10. This solution limits the distance between the heating element 400 and the fan blade 120 in the axial direction of the fan blade 120 to ensure a good heating effect for the fan 10. D2 can be 10mm, 12mm, 15mm, 18mm, 20mm, 22mm, or 25mm, etc., and is not specifically limited here.

[0120] Please see Figure 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, the distance between the end of the fan blade 120 near 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] Understandably, by limiting the size of D3, it can be ensured that the downward projection of some or all of the fan blades 120 falls into the air inlet 112. As mentioned above, the air entering through the air inlet 112 along the radial direction of the fan blades 120 can be dispersed by the rotating fan blades 120 and then blown out from the air outlet of the mesh cover 110. This reduces the wind resistance of the air entering from the air inlet 112, thereby reducing the noise generated by this air reversal. D3 can be 5mm, 8mm, 10mm, or 15mm, etc., and can be set according to the height H of the fan blades 120 along their axial direction. It is not limited here.

[0122] In one embodiment, at least a portion of the fan blades 120 are projected vertically onto the humidification device 300, the mist outlet 310 is opened upwards and located on the air outlet side of the heating element 400 along the axial direction of the fan blades 120, and the air inlet 112 is projected vertically onto the outside of the mist outlet 310 and located between the mist outlet 310 and the air inlet end of the mesh cover 110. With this configuration, the fan blade 120 is positioned directly above the humidifier 300. 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 forward with the air outlet end of the mesh cover 110. The water mist will not enter the mesh cover 110 along the air inlet 112 and cause the heating element 400 to fail. This avoids the influence of water mist on the heating element 400 and improves the service life of the fan 10.

[0123] Please see Figure 4 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. The distance between 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 is D4, where D4 ≥ 50 mm.

[0124] It is 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 not less than 50mm, it is ensured that when the water mist is sprayed upward, it will flow towards the air outlet of the mesh cover 110, and the water mist will not enter the mesh cover 110 and affect the heating element 400. Among them, D4 can be 50mm, 55mm, 60mm, or 70mm, etc., and is not specifically limited here.

[0125] Please see Figure 12 , Figure 13 , Figure 16 and Figure 17 In one embodiment, the fan 10 further includes a filter 700, which is detachably disposed on and located outside the mesh cover 110 for filtering the air drawn in and / or blown out by the fan blades 120.

[0126] It is understood that the filter element 700 is disposed outside the mesh cover 110 and detachably connected to the mesh cover 110. The detachable connection can be made in various ways, such as, but not limited to, snap-fit ​​connections or screw connections, depending on the specific requirements. The filter element 700 may include a filter screen 710 for filtering air. Furthermore, the filter element 700 can be disposed on the air inlet side of the mesh cover 110 to filter the intake air; the filter element 700 can also be disposed on the air outlet side of the mesh cover 110 to filter the exhaust air; of course, the filter element 700 can be disposed on both the air inlet and air outlet sides of the mesh cover 110 to achieve dual filtration and improve the filtration effect. Therefore, the fan 10 of this application also has the function of purifying air.

[0127] Please see Figure 16 and Figure 17 In one embodiment, the mesh cover 110 has an air inlet side, and the fan 10 further includes a drive member 130, which is drivenly connected to the fan blade 120. The drive member 130 is disposed inside the mesh cover 110 and extends outward toward the air inlet side to the outside of the mesh cover 110.

[0128] Understandably, the drive unit 130 includes a drive motor connected to the fan blade 120 to drive the fan blade 120 to rotate. The mesh cover 110 has an air inlet end and an air outlet end. When the fan blade 120 rotates, air is drawn in from the air inlet end of the mesh cover 110, passes through the airflow channel of the mesh cover 110, and is discharged from the air outlet end of the mesh cover 110.

[0129] Furthermore, the drive component 130 is located inside the mesh cover 110, occupying a certain space inside the mesh cover 110. In this solution, the drive component 130 extends out of the mesh cover 110 towards the air intake side, reducing the space occupied by the drive component 130 inside the mesh cover 110 and utilizing the space outside the mesh cover 110. This is beneficial for improving the space utilization rate inside and outside the mesh cover 110, for miniaturizing the mesh cover 110, and for heat dissipation of the drive component 130.

[0130] In one embodiment, the filter element 700 is located on the air inlet side, and the filter element 700 is provided with a clearance portion for avoiding the drive element 130. It is understood that the filter element 700 is disposed outside the mesh cover 110 and located on the air inlet side of the mesh cover 110. The end of the drive element 130 facing the air inlet side extends out of the mesh cover 110. To avoid interference between the filter element 700 disposed on the mesh cover 110 and the protruding part of the drive element 130, the filter element 700 is provided with a clearance portion. The clearance portion can be perforated, grooved, or other shapes, and is not limited here. By providing the clearance portion, the drive element 130 can smoothly extend out of the mesh cover 110, and the arrangement structure of the filter element 700 and the drive element 130 disposed outside the mesh cover 110 is compact, resulting in better overall integrity of the fan 10.

[0131] In one embodiment, the filter element 700 includes a filter screen 710, the filter screen 710 having a clearance hole 711, the filter screen 710 being disposed outside the mesh cover 110 and located on the air inlet side, and the drive member 130 being disposed outside the mesh cover 110 being disposed inside the clearance hole 711.

[0132] It is understood that the material of the filter screen 710 can be various, such as polyester screen, fiber screen, or nylon screen, etc., and there is no specific limitation here. The clearance hole 711 can be set in the middle of the filter screen 710 or any other position. In this embodiment, the center line of the clearance hole 711 coincides with the center line of the filter screen 710. The filter screen 710 is sleeved on the drive member 130 located outside the mesh cover 110 through the clearance hole 711. In this way, the space on the air inlet side of the mesh cover 110 is fully utilized. The filter screen 710 and the drive member 130 do not interfere with each other, and their structures are arranged compactly. The overall space utilization of the fan 10 is high, which is conducive to the miniaturization of the fan 10 and the reduction of material usage, thereby helping to reduce production costs.

[0133] In one embodiment, the filter element 700 further includes a filter cover 720, which is disposed outside the mesh cover 110 and covers the filter mesh 710; the filter cover 720 is provided with air passage holes and clearance grooves, the filter mesh 710 is disposed corresponding to the air passage holes, and the end of the drive member 130 located outside the mesh cover 110 is disposed in the clearance groove.

[0134] It is understandable that the filter cover 720 is provided with air passage holes, which are correspondingly set with the filter screen 710. When the fan blade 120 rotates, the air drawn in by the fan blade 120 passes through the air passage holes and the filter screen 710 in sequence and enters the mesh cover 110. After flowing along the airflow channel of the mesh cover 110, it is discharged from the air outlet side of the mesh cover 110. The air passage holes are used to allow air to pass through.

[0135] Furthermore, the filter cover 720 is also provided with a relief groove for accommodating the end of the drive member 130 that protrudes outside the mesh cover 110. By providing the relief groove, the end of the drive member 130 is covered inside the filter cover 720, and the filter cover 720 can protect the drive member 130, which helps to improve the safety of the fan 10.

[0136] In one embodiment, the filter cover 720 has a groove on the side facing the mesh cover 110, and a limiting part is provided at the opening of the groove. The limiting part and the bottom of the groove are spaced apart to form a limiting groove. The filter mesh 710 is disposed in the limiting groove, and the clearance groove is disposed at the bottom of the limiting groove.

[0137] It is understood that the limiting part can be a limiting block or a limiting ring, and there is no specific limitation here. In this embodiment, the limiting part includes multiple limiting blocks. The multiple limiting blocks are arranged sequentially and at intervals around the circumference of the filter cover 720 on the groove sidewall of the groove to form a limiting groove with the groove. The filter element 700 is disposed in the limiting groove. The limiting blocks limit 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 understood that there are various ways to achieve this detachable connection, such as a snap-fit ​​connection or a connection via a connector. In this embodiment, the mesh cover 110 has a groove on its outer surface facing the air inlet side, and the filter element 700 is disposed within the groove. This arrangement facilitates the installation of the filter element 700.

[0139] In one embodiment, one of the filter cover 720 and the mesh cover 110 is provided with a buckle, and the other is provided with a slot, the buckle engaging with the slot. It is understood that the buckle can be a rotary buckle, and the slot is adapted to the rotary buckle. When installing the filter cover 720, rotating the filter cover 720 will cause the rotary buckle to engage in the slot. In this embodiment, the outer peripheral wall of the filter cover 720 is provided with a rotary buckle, and the side wall of the groove is provided with a slot, thus facilitating the installation of the filter cover 720 into the groove of the mesh cover 110.

[0140] In one embodiment, the filter cover 720 is provided with a first screw hole, and the mesh cover 110 is provided with a second screw hole. 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, thus ensuring the stability of the filter cover 720 installed on the mesh cover 110.

[0141] Please see Figure 16 and Figure 17In one embodiment, the filter cover 720 is further provided with a first heat dissipation hole 721, and the drive member 130 is provided with a second heat dissipation hole 131, wherein the first heat dissipation hole 721 and the second heat dissipation hole 131 are connected.

[0142] Understandably, the first heat dissipation hole 721 is located outside the mesh cover 110. The drive component 130 includes a housing, and the drive motor is located inside the housing. The housing is provided with a second heat dissipation hole 131 that communicates with the first heat dissipation hole 721. Air outside the filter cover 720 can pass through the first heat dissipation hole 721 and the second heat dissipation hole 131 to enter the housing to dissipate heat from the drive motor. Of course, the housing is also provided with a third heat dissipation hole to allow air to be discharged outside the housing. This can improve the heat dissipation effect of the drive motor and improve the stability of the fan 10 operation.

[0143] In addition, the third heat dissipation hole is located inside the mesh cover 110. That is to say, the air that the drive motor dissipates heat 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 drive motor dissipates heat and the air heated by the heating element 400 are combined and blown out from the exhaust side of the mesh cover 110, which helps to improve the heating effect of the fan 10.

[0144] Please see Figure 18 and Figure 19 In one embodiment, the fan 10 further includes a plasma ion generator 800 disposed inside the mesh cover 110 for generating plasma ions inside the mesh cover 110.

[0145] Understandably, the ion generator 800 is used to produce clean ions, which are positive and negative ion clusters. The combination of positive and negative ions surrounds and decomposes harmful substances such as airborne mold and viruses. Upon attaching to the surface of airborne bacteria, the ions in the ion cluster generate OH- (hydroxyl) free radicals, the most potent oxidizing agents. These free radicals extract H+ (hydrogen ions) from the proteins of the airborne bacteria, rendering them inactive and causing their death. The H2O generated by the combination of OH- and H+ is then returned to the air as water molecules, achieving air purification. Furthermore, clean ions can inhibit the growth and reproduction of attached mold, further eliminating odors and unpleasant smells. In addition, the ion generator 800 can be mounted on the mesh cover 110, or it can be fixed using a mounting bracket. The specific location is not limited, as long as the clean ions generated by the ion generator 800 can flow with the air within the airflow channel.

[0146] Therefore, it can be seen that the ion generator 800 in this solution can generate ions, which are discharged into the room with the air in the airflow channel of the mesh cover 110 to sterilize the indoor air and inhibit the growth of bacteria in the air, thus removing odors. In other words, the fan 10 in this solution also has the function of sterilizing and removing odors from the air, and the fan 10 of this application has high practicality.

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

[0148] It is understood that the heat insulation component 600 can be arranged in a ring shape. The heat insulation component 600 is used to insulate the heat of the heat-generating component 400 to prevent the heat of the heat-generating component 400 from being transferred to the mesh cover 110. In one embodiment, the fan 10 also includes a drive component 130, which is mounted on the heat insulation component 600. The drive component 130 can be a drive motor, that is, the drive motor is mounted on the heat insulation component 600. This makes the internal structure of the mesh cover 110 compact, the utilization rate of the heat insulation component 600 high, and eliminates the need for additional fasteners. This is beneficial for the miniaturization of the fan 10 and the reduction of material usage, thereby reducing the production cost of the fan 10.

[0149] Furthermore, the ion generator 800 can be mounted on the mesh cover 110 or on the heat insulation component 600. Alternatively, it can be partially mounted on the mesh cover 110 and partially on the heat insulation component 600; the specific configuration can be determined as needed and is not limited here. When the ion generator 800 is mounted on the heat insulation component 600, the arrangement of the heat insulation component 600 and the ion generator 800 is compact, resulting in high utilization of the heat insulation component 600. The ion generator 800 and the heating element 400 are spaced apart to prevent the heat generated by the heating element 400 from damaging or burning the ion generator 800, thus extending the service life of the ion generator 800.

[0150] In one embodiment, the heat insulation member 600 and the mesh cover 110 enclose a cavity, and the ion generator 800 is disposed in the cavity. The ion generator 800 includes an ion emission head 810, which extends out of the cavity toward the heating member 400.

[0151] Understandably, the ion generator 800 is housed within the cavity formed by the heat insulation component 600 and the mesh cover 110. The cavity not only serves to house the ion generator 800 but also to shield it. This allows the heat insulation component 600 to protect the ion generator 800 and prevents it from being fully exposed within the mesh cover 110, thereby improving the aesthetics of the fan 10.

[0152] Furthermore, the ion emitter 810 has an ion emission port 811, which extends out of the housing cavity and is spaced apart from the heating element 400. This facilitates the emission of ions generated by the ion emitter 810 to the outside of the housing cavity. In other words, the ions generated by the ion emitter 810 can be directly emitted into the airflow channel and flow into the room with the air, so as to realize the function of sterilizing and removing odors from the indoor air.

[0153] Please see Figure 19 In one embodiment, the ion generator 800 further includes a generator body 820 connected to the ion emitter 810. The generator body 820 is disposed in the accommodating cavity. The mesh cover 110 and / or the heat insulation member 600 are provided with mounting holes communicating with the accommodating cavity, and the ion emitter 810 passes through the mounting holes.

[0154] It is understood 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 to ionize and generate net ions. The generated net ions are emitted through the net ion emitter 810. The mounting hole is provided on the mesh cover 110; or, the mounting hole is provided on the heat insulation component 600; or, the mesh cover 110 and the heat insulation component 600 enclose to form a mounting hole, and the heating element 400 is spaced apart from the mounting hole. The net ion emitter 810 passes through the mounting hole, and the end of the net ion emitter 810 near the heating element 400 is provided with a net ion emission port 811. The net ion emission port 811 is located between the mounting hole and the heating element 400. With this arrangement, when the heating element 400 is working, the net ions emitted from the net ion emission port 811 can also be heated, thereby improving the sterilization effect of the net ions.

[0155] Please see Figure 18 In one embodiment, the heat insulation component 600 includes a heat insulation ring 610 and a cover 620. The heat insulation ring 610 is sleeved on the heating component 400, the ion generator 800 is disposed on the mesh cover 110, and the cover 620 is disposed on the outer peripheral wall of the heat insulation ring 610 and covers the ion generator 800. The cover 620 and the mesh cover 110 enclose each other to form the mounting hole.

[0156] Understandably, the mesh cover 110 can be provided with mounting positions, within which both the generator body 820 and the ion emitter 810 can be placed. The cover 620 covers the generator body 820 and the ion emitter 810 to fix and protect them. Furthermore, the mounting hole is formed by the cover 620 and the mesh cover 110, facilitating the insertion of the ion emitter 810 into the mounting hole, and the ion emission port 811 of the ion emitter 810 easily protrudes out of the mounting hole. Therefore, this design allows the ion generator 800 to be stably installed inside the mesh cover 110, and prevents the heat generated by the heating element 400 from burning out the ion generator 800, thereby improving the reliability of the fan 10.

[0157] In one embodiment, the ion emitter 810 has an ion emission port 811, which is spaced apart from the heating element 400. The ion emission port 811 is located radially between the inner peripheral wall of the heat insulation ring 610 and the heating element 400.

[0158] Understandably, the opening direction of the ion emission port 811 can be set towards the heating element 400, which is located within the airflow channel of the mesh cover 110. This allows the ions emitted from the ion emission port 811 to be smoothly discharged into the room along the airflow channel. Furthermore, the ion emission port 811 is located radially along the heat insulation ring 610 between the inner peripheral wall of the heat insulation ring 610 and the heating element 400. The annular structure of the heat insulation ring 610 forms an airflow channel, meaning that the ion emission port 811 is located on the outer peripheral side of the heating element 400 and within the airflow channel of the heat insulation ring 610. This fully utilizes the internal space of the heat insulation ring 610, resulting in high internal space utilization and improving the smoothness of the flow of ions within the airflow channel.

[0159] In one embodiment, the mesh cover 110 is rotatably mounted on the support member 210, and the axis of rotation of the mesh cover 110 is arranged in the horizontal direction; and / or, the support member 210 is rotatably mounted on the base 220, and the axis of rotation of the support member 210 is arranged in the vertical direction. It is understood that the horizontal axis of rotation of the mesh cover 110 allows the fan to oscillate up and down; the vertical axis of rotation of the support member 210 allows the fan to oscillate left and right. This arrangement enables the fan 10 to oscillate up and down and left and right. The specific structures of the up-and-down oscillation drive mechanism and the left-and-right oscillation drive mechanism can be referred to the foregoing description and are not limited here.

[0160] Please see Figure 1 and Figure 2In one embodiment, the support member 210 includes a column segment 211, a column inclined segment 212, and a column bracket 213 with an opening. The column inclined segment 212 is connected to the upper end of the column segment 211 and is inclined upward. The column bracket 213 is connected to the column inclined segment 212. The mesh cover 110 is disposed at the opening and is rotatably connected to the opposite ends of the column bracket 213.

[0161] It is understandable that the column tilting section 212 tilts upwards, that is, there is an angle between the column rod section 211 and the column tilting section 212. By setting this angle, the column support 213 can also be tilted, thereby adjusting the position of the mesh cover 110 so that the downward projection of the air inlet 112 of the lower half of the mesh cover 110 falls on the base 220 and is spaced apart from the support member 210. This improves the smoothness of air entering the mesh cover 110 along the air inlet 112.

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

[0163] Please see Figure 2 In one embodiment, the column segment 211 is arranged vertically, and the angle between the column inclined segment 212 and the column segment 211 is α, wherein 105°≤α≤150°; and / or, the opening of the column support 213 is arranged upward, and on the axial projection plane of the fan blade 120, the angle between the column inclined segment 212 and the column support 213 is β, wherein 60°≤β≤105°.

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

[0165] On the axial projection plane of the fan blade 120, the included angle between the inclined column section 212 and the column support 213 can be 60°, 70°, 80°, 90°, 100°, or 105°, etc., and is not specifically limited here. By limiting the size of β, the tilt angle of the column support 213 relative to the column rod section 211 is limited, which also limits the position of the fan head 100 relative to the column rod section 211. The lower half of the middle shell 111 is provided with an air inlet 112. 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 inclined column section 212 and the column support 213 cooperate to reduce the air resistance, that is, reduce the wind resistance of air entering the mesh cover 110 through the column assembly, thereby helping to increase the air intake volume into the mesh cover 110. Therefore, this solution is beneficial for increasing the air intake of fan 10.

[0166] Please see Figures 4 to 6 In one embodiment, the fan 10 further includes a water receiving component 900, the base 220 has a receiving cavity 221, the support member 210 is rotatably disposed on the base 220, the rotation axis of the support member 210 is arranged in the vertical direction, the support member 210 and the base 220 have a rotation gap 222, the rotation gap 222 communicates with the receiving cavity 221; the water receiving component 900 is disposed in the receiving cavity 221 to receive water flowing into the rotation gap 222.

[0167] It is understood that the specific structure of the water receiving component 900 is not limited. The water receiving component 900 can be partially inserted into the rotation gap 222, or it can be located below the rotation gap 222, as long as it can collect the water flowing into the rotation gap 222. The water in the water receiving component 900 can be collected through a water storage component, or it can be discharged to the outside of the base 220 through the drainage channel 950. Specific details are not limited here, and will be discussed later. By setting up the water receiving component 900, water is prevented from flowing into the base 220 from the rotation gap 222 and coming into contact with the electrical control components inside the base 220, thereby preventing short circuits in the electrical control components.

[0168] Please see Figure 5 In one embodiment, the base 220 includes a top cover 223, the top cover 223 is provided with a first mounting hole 224 communicating with 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 understood that the support member 210 can be connected to the base 220 via a left-right oscillation drive mechanism. That is, the fan 10 also includes a left-right oscillation drive mechanism, which is located at the first mounting hole 224 and is driven by the support member 210. The support member 210 can be entirely located outside the first mounting hole 224, or it can be inserted into the first mounting hole 224. There are no specific limitations here, as long as the support member 210 can rotate relative to the base 220. The first water receiving tank 910 can be set in a recessed trough shape or in an annular groove 214 shape; there are no specific limitations here. The edge of the first mounting hole 224 is the edge of the opening of the first mounting hole 224. The projection of the edge of the first mounting hole 224 in the vertical direction falls into the first water receiving tank 910. That is, water flowing into the rotation gap 222 along the edge of the first mounting hole 224 can fall downwards into the first water receiving tank 910, thereby achieving the function of collecting water.

[0170] Please see Figure 5 In one embodiment, the edge of the first mounting hole 224 is provided with an outwardly extending first water-blocking platform 225, which is arranged in a ring shape. It is understood that when water is splashed onto the base 220, if the height of the water droplets or flow does not exceed the height of the first water-blocking platform 225, the water cannot flow into the rotation gap 222. That is, the first water-blocking platform 225 can block some water from flowing into the rotation gap 222, thus improving the safety of the fan 10.

[0171] In one embodiment, a second water-retaining platform 226 extending inward is provided at the edge of the first mounting hole 224. The second water-retaining platform 226 is arranged in a ring shape, and its downward projection falls into the first water receiving groove 910. This arrangement allows the second water-retaining platform 226 to guide the water flowing into the first water receiving groove 910 along the wall of the first mounting hole 224, ensuring that all water flowing along the inner wall of the first mounting hole 224 flows into the first water receiving groove 910. Simultaneously, the height difference between the bottom end of the second water-retaining platform 226 and the inner wall of the upper cover 223 prevents water from flowing along the edge of the first mounting hole 224 across the inner wall of the upper cover 223 and contacting the electrical control components in the accommodating cavity 221, thus improving the safety of the fan 10. In one embodiment, the bottom end of the second water-retaining platform 226 is located within the first water receiving groove 910, which further enhances the guiding effect of the second water-retaining platform 226.

[0172] In one embodiment, the water receiving component 900 is provided with a second mounting hole 920. The lower end of the support component 210 passes through the first mounting hole 224 and the second mounting hole 920 and is rotatably connected to the base 220. The first water receiving groove 910 is arranged in a ring around the second mounting hole 920. This arrangement, where the lower end of the support component 210 passes through the water receiving component 900 and is located within the receiving cavity 221, and the position where the support component 210 is driven to connect with the base 220 is relatively low, facilitates the installation of the left and right oscillation drive mechanism and also improves the stability of the support component 210 rotating on the base 220. The second mounting hole 920 avoids the support component 210, allowing it to pass through; the first water receiving groove 910 is arranged in a ring around the second mounting hole 920, so that the first water receiving groove 910 can receive water flowing into the rotation gap 222 from all directions.

[0173] In one embodiment, an annular groove 214 is provided on the outer peripheral wall of the lower end of the support member 210. The hole wall of the first mounting hole 224 and the hole wall of the second mounting hole 920 are disposed in the annular groove 214. The diameter of the first mounting hole 224 is larger than the diameter of the second mounting hole 920. With this configuration, the downward projection of the lower outer peripheral wall of the support member 210 falls outside the first mounting hole 224, thus preventing some water from falling into the rotation gap 222. Furthermore, the wall of the second mounting hole 920 is located within the annular groove 214, with the groove opening of the annular groove 214 facing outward in the horizontal direction. This creates a meandering structure between the rotation gap 222 and the support member 210, making it difficult for water spilled on the base 220 to flow into the rotation gap 222. Moreover, the diameter of the first mounting hole 224 is larger than that of the second mounting hole 920, causing water flowing into the rotation gap 222 to flow into the first water receiving groove 910. This ensures that the water receiving member 900 can collect the water flowing into the rotation gap 222, giving the fan 10 of this application a high level of safety.

[0174] Please see Figure 6 In one embodiment, the water receiving component 900 is further provided with a drainage channel 950, and the bottom end of the base 220 is provided with a drain outlet 227. The drainage channel 950 connects the first water receiving tank 910 and the drain outlet 227. It is understood that the water in the first water receiving tank 910 can be stored by a water storage component, or it can be discharged outside the base 220. This solution adopts the method of draining the water out of the base 220. The drain outlet 227 can be located on the bottom wall of the lower cover of the base 220, or it can be located on the side wall of the lower cover; the specific location is not limited here. By providing a drainage channel 950 on the water receiving component 900, the collected water can be discharged from the base 220 in a timely manner, which helps to improve the safety of the fan 10.

[0175] Please see Figure 5 In one embodiment, the fan 10 further includes a mounting bracket 930, on which a second water inlet 940 is provided. The bottom end of the support member 210 is located in the second water inlet 940 and is rotatably connected to the mounting bracket 930. The second water inlet 940 is connected to the drainage channel 950.

[0176] Understandably, by setting up the second water receiving trough 940, water not collected by the first water receiving trough 910 can be further collected, ensuring that all water flowing into the rotation gap 222 is collected, thus improving the safety of the fan 10. The second water receiving trough 940 is located below the first water receiving trough 910. A positioning part is provided within the second water receiving trough 940, and a rotating bearing is provided on the positioning part. The bottom end of the support member 210 is fitted onto the rotating bearing, allowing the support member 210 to be rotatably connected to the mounting bracket 930. The second water receiving trough 940 communicates with the drainage channel 950, allowing the water collected in the second water receiving trough 940 to be discharged from the base 220 in a timely manner, thus improving the safety of the fan 10.

[0177] In one embodiment, a flow guiding area is formed on the outer surface of the upper cover 223. The flow guiding area is inclined downward from its center toward the periphery, and the first mounting hole 224 is located near the center of the flow guiding area. This configuration, where the outer surface of the upper cover 223 is higher in the middle and lower at the edges, and the first mounting hole 224 is located near the center of the outer surface of the upper cover 223, ensures that water spilled on the outer surface of the upper cover 223 flows towards the edges, preventing water from accumulating in the center and flowing into the rotation gap 222. This helps reduce the amount of water flowing into the base 220.

[0178] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
