During this process, the mist continuously impacts the front net of the fan, which may easily cause condensation or even water accumulation at the front net of the fan. When the fan is shaking, the water droplets on the front net will drip into the inside of the fan, posing a safety and quality hazard and affecting the user experience. Utility Model Content

When the mist is sprayed out from the mist outlet, due to the high pressure around the mist outlet, the mist will not disperse to the position with higher pressure around it, but will be sprayed out more concentratedly, thus reducing the probability of the mist being sucked into the air duct cavity, thereby eliminating the phenomenon of water condensation at the air outlet net caused by the mist impacting the air outlet net, effectively solving the problem of water condensation at the air outlet net, eliminating safety and quality risks, and improving the user experience.

[0041] The existing fan with humidification function generally has an atomizing nozzle arranged at the center of the front net of the fan. When the fan is running, the atomizing nozzle sprays mist into the environment at the same time to achieve the effect of humidifying the environment.

[0042] However, the applicant found that after the above-mentioned fan has been running in humidification mode for a period of time, condensation will occur at the front mesh of the fan, and even water accumulation will occur. As the fan runs in different modes, there is a risk that the water droplets at the front mesh of the fan will fall into the inside of the fan head, posing a safety and quality hazard.

[0043] During the analysis, the applicant found that the center of the fan front mesh was blocked by the fan blade hub and the motor, which made the wind speed at the center of the fan front mesh very low, and the wind speed at the position of the fan front mesh corresponding to the fan blade was higher. Since the higher the wind speed, the lower the pressure, this makes the center of the fan front mesh a high-pressure area, and the position of the fan front mesh corresponding to the fan blade a low-pressure area. When the atomizing nozzle set at the center of the fan front mesh sprays mist, the mist will be offset and dispersed toward the low-pressure areas on both sides under the action of negative pressure, and then there is a situation where it is sucked to the fan blades. In this process, the mist continuously impacts the fan front mesh, which easily causes condensation water or even water accumulation at the fan front mesh. When the fan is running in a shaking head or other mode, the water droplets on the fan front mesh will drip into the inside of the fan, creating safety and quality risks and affecting the user experience.

[0044] Regarding the problem that the mist of existing fans with humidification function is sucked out and causes condensation on the fan front screen, see Figure 1 and Figure 2 An embodiment of the present application provides a fan head, which is suitable for connecting to an atomization generator (not shown in the figure), and the fan head includes an air duct assembly 100 and an air outlet net 200.

[0045] The air duct assembly 100 includes an air duct housing 110 and a fan blade 120 rotatably mounted in the air duct housing 110 . The air duct housing 110 and the fan blade 120 together form an air duct cavity 130 surrounding the fan blade 120 .

[0046] The air outlet net 200 is covered on the air outlet side of the air duct cavity 130 , and a mist outlet 210 is provided on the air outlet net 200 . The mist outlet 210 is connected to the output end of the atomizer generator, and the axis of the mist outlet 210 deviates from the axis of the air duct cavity 130 .

[0047] It should be noted that the fan head of the embodiment of the present application can be configured on atomizing fans such as atomizing floor fans, atomizing table fans, atomizing handheld fans, and atomizing folding fans. It is understandable that when the fan head of the embodiment of the present application is configured on atomizing fans, the output end of the atomizing generator on the atomizing fan is connected to the mist outlet 210 on the air outlet network 200 through the corresponding pipeline path inside the atomizing fan.

[0048] The atomizer is a conventional ultrasonic vibration atomizer or a compression atomizer. The atomizer generator transmits small water droplets to the mist outlet 210 of the air outlet network 200. The small water droplets are sprayed out from the mist outlet 210 in a mist state. The mist is spread in the ambient air under the push of the air flow, achieving the effect of rapid cooling and humidification.

[0049] It should also be noted that in the embodiment of the present application, the air duct housing 110, the air outlet net 200 and the mist outlet 210 on the air outlet net 200 are preferably regular rotating body structures. The axis of the mist outlet 210 is the central axis of the mist outlet 210, and the axis of the air duct cavity 130 is the central axis of the air duct cavity 130.

[0050] It is not difficult to understand that the axis of the air duct cavity 130 coincides with the axis of the air outlet net 200, and the axis of the mist outlet 210 deviates from the axis of the air duct cavity 130, that is, the axis of the mist outlet 210 does not coincide with the axis of the air outlet net 200, and the axis of the mist outlet 210 is parallel to the axis of the air outlet net 200 and there is a certain distance between the two.

[0051] Such arrangement makes the position of the mist outlet 210 on the air outlet net 200 offset by a certain distance relative to the center of the air outlet net 200, avoiding the mist outlet 210 being in the high-pressure area at the center of the air outlet net 200, making the position of the mist outlet 210 offset relative to the high-pressure area at the center of the air outlet net 200, and correspondingly reducing the pressure at the mist outlet 210, thereby making the pressure at the mist outlet 210 lower than the pressure around it. When the mist is sprayed out from the mist outlet 210, due to the high pressure around the mist outlet 210, the mist will not disperse to the position with higher pressure around it, but will be sprayed out more concentratedly, thus reducing the probability of the mist being sucked into the air duct cavity 130, thereby eliminating the phenomenon of condensation at the air outlet net 200 caused by the mist impacting the air outlet net 200, effectively solving the problem of condensation at the air outlet net 200, eliminating safety and quality risks, and improving the user experience.

[0052] In some embodiments of the present application, see Figure 1 and Figure 2 The fan blade 120 is configured to be able to rotate in the air duct cavity 130 to define an air flow belt with the air duct cavity 130 and the air outlet net 200. The air outlet net 200 has a maximum wind speed area in the air flow belt, and the mist outlet 210 is set in the maximum wind speed area.

[0053] Specifically, see Figure 5 and Figure 6The air duct assembly 100 further includes a motor 160 and a fan knob 170. The air duct housing 110 is constructed as a cylindrical housing. A first threaded hole 112 is provided at the center of the air duct housing 110. The motor 160 has a threaded column 161. The threaded column 161 of the motor 160 is threadedly connected to the threaded hole 112 of the air duct housing 110 to achieve fixed installation of the motor 160. At the same time, the fan blade 120 has a coaxially connected positioning hole 121 and a second threaded hole. The positioning hole 121 of the fan blade 120 is positioned and inserted on the motor shaft 162 of the motor 160. The fan knob 170 is threadedly installed in the second threaded hole. In this way, the fan blade 120 is fixedly installed.

[0054] It can be understood that the motor 160 drives the fan blade 120 to rotate around its own axis, and after the ambient air is introduced into the air duct cavity 130, the fan blade 120, the air duct cavity 130 and the air outlet net 200 define an air flow belt, and the air flow moves in the air flow belt and blows toward the air outlet net 200 to achieve a blowing effect.

[0055] It is not difficult to understand that the airflow has different wind speeds when passing through each mesh port of the air outlet net 200, that is, there are low wind speed areas, medium wind speed areas, and high wind speed areas on the air outlet net 200. Through simulation calculations of fluid simulation software and actual use tests, the maximum wind speed area of ​​the air outlet net 200 in the air flow belt can be obtained, and the mist outlet 210 is set in the maximum wind speed area.

[0056] Since the mist outlet 210 is located at the maximum wind speed zone of the air outlet net 200 in the air flow belt, according to the principle that the greater the wind speed, the smaller the pressure, the pressure at the mist outlet 210 is the smallest on the air outlet surface formed by the air outlet net 200, and the pressure around the mist outlet 210 is greater than or equal to the pressure at the mist outlet 210. Therefore, when the mist is sprayed out from the mist outlet 210, the mist will not disperse to the surrounding high pressure position, but will be sprayed out more concentratedly, so that the mist sprayed from the mist outlet 210 can be prevented from being sucked into the air duct cavity 130 under the action of the surrounding negative pressure, thereby directly eliminating the phenomenon of condensation at the air outlet net 200 caused by the fog impacting the air outlet net 200, effectively solving the problem of condensation at the air outlet net 200, eliminating safety and quality risks, and improving the user experience.

[0057] In some embodiments of the present application, see Figure 3 and Figure 4 The air outlet net 200 includes a central decorative portion 220 and an air outlet portion 230 surrounding the central decorative portion 220 , and the mist outlet 210 is located at the air outlet portion 230 .

[0058] Specifically, the air outlet net 200 is circular in shape as a whole, and the central decorative part 220 is constructed as a circular structural plate, the axis of which coincides with the axis of the air outlet net 200. The air outlet part 230 includes a collar and a plurality of spokes, and the two ends of each spoke are respectively connected to the central decorative part 220 and the collar, so that all the spokes are radially distributed in a ring shape between the central decorative part 220 and the collar. It can be understood that a mesh opening for airflow to pass through is formed between two adjacent spokes.

[0059] Since the central decorative part 220 is a solid structural plate, when the airflow is blown out through the air outlet net 200, the central decorative part 220 has a certain stopping effect on the airflow, resulting in a lower wind speed and higher pressure at the location of the central decorative part 220. If the mist outlet 210 is set on the central decorative part 220, when the mist is sprayed out from the mist outlet 210, it will be sucked into the air duct cavity 130 through the mesh port of the air outlet part 230 under the action of the pressure difference, causing condensation to appear on the air outlet part 230.

[0060] Based on this, the fan head of the embodiment of the present application directly sets the mist outlet 210 on the air outlet part 230, so that the air outlet part 230 is at a position with lower pressure. When the mist is sprayed out from the mist outlet 210, due to the higher pressure around the mist outlet 210, the mist will not disperse to the position with higher pressure around it, but will be sprayed out more concentratedly. In this way, the probability of the mist being sucked into the air duct cavity 130 can be reduced, thereby eliminating the phenomenon of condensation at the air outlet net 200 caused by the fog impacting the air outlet net 200, effectively solving the problem of condensation at the air outlet net 200, eliminating safety and quality risks, and improving user experience.

[0061] Further, see Figure 4 The outer wall of the central decorative part 220 forms a first annular edge 221, the inner wall of the air outlet part 230 forms a second annular edge 231 which is concentrically distributed with the first annular edge 221, and a third annular edge 240 is provided between the first annular edge 221 and the second annular edge 231. The distance between the third annular edge 240 and the first annular edge 221 is equal to the distance between the third annular edge 240 and the second annular edge 231, and the mist outlet 210 is located at the third annular edge 240.

[0062] Specifically, the air outlet net 200 and the central decorative portion 220 are both circular structures, and the air outlet portion 230 is a circular ring structure. It can be understood that the center of the central decorative portion 220 is the center of the air outlet net 200, and the first annular edge 221, the third annular edge 240 and the second annular edge 231 are concentrically distributed with the center of the central decorative portion 220 as the center of the circle, and the radii of the three increase in sequence.

[0063] With the center of the air outlet net 200 as the center of the circle, along the radial direction, a line connecting a point on the outer edge of the central decorative portion 220 and a point on the inner edge of the air outlet portion 230 is set as a connecting line, and the midpoints of all the connecting lines are connected end to end to form a third annular edge 240. At this time, the distance between the third annular edge 240 and the first annular edge 221 is equal to the distance between the third annular edge 240 and the second annular edge 231.

[0064] When the fan blade 120 rotates, the fan blade 120, the air duct cavity 130 and the air outlet net 200 define an air flow belt. Through simulation calculations of fluid simulation software and actual use tests, it is found that the maximum wind speed area of ​​the air outlet net 200 in the air flow belt is approximately located at the aforementioned third annular edge 240. In other words, at various positions on the air outlet net 200, the wind speed at any point on the third annular edge 240 is approximately equal, and is greater than the wind speed at other positions on the air outlet net 200.

[0065] Based on this, the mist outlet 210 is set at any point on the third annular edge 240, so that the mist outlet 210 can be located at the maximum wind speed on the air outlet net 200. In this way, when the fan blade 120 rotates, the pressure at the mist outlet 210 on the air outlet net 200 is the lowest. When the mist is sprayed out from the mist outlet 210, since the pressure around the mist outlet 210 is higher than the pressure at the mist outlet 210, the mist will not disperse to the surrounding positions with higher pressure, but will be sprayed out more concentratedly. In this way, the probability of the mist being sucked into the air duct cavity 130 can be reduced, thereby eliminating the phenomenon of condensation at the air outlet net 200 caused by the fog impacting the air outlet net 200, effectively solving the problem of condensation at the air outlet net 200, eliminating safety and quality risks, and improving user experience.

[0066] In addition, it should be supplemented that a ring strip can be detachably provided on the air outlet net 200 , and the ring strip surrounds and forms the mist outlet 210 , so that the mist outlet 210 can be conveniently provided at a predetermined position of the air outlet net 200 .

[0067] See also Figure 1 and Figure 2 In some embodiments of the present application, a mist passage 111 is provided on the air duct shell 110, and the two ends of the mist passage 111 are respectively a first port 1111 and a second port 1112, the first port 1111 is connected to the mist outlet 210, and the second port 1112 is connected to the output end of the atomization generator.

[0068] Specifically, the mist passage 111 may be a sealed passage opened on the outer wall of the air duct housing 110. The output end of the atomization generator may be connected to the second port 1112 through a pipeline, and the mist outlet 210 is directly connected to the first port 1111 of the mist passage 111.

[0069] It is understandable that the atomizer generator has a pressure pump. When the atomizer generator is working, the output end of the atomizer generator outputs small water droplets. Under the pumping action of the pressure pump, the small water droplets are transported to the mist outlet 210 along the mist passage 111, and then sprayed out from the mist outlet 210 in the form of water mist.

[0070] It is not difficult to understand that the embodiment of the present application sets a mist passage 111 on the air duct shell 110, and makes the mist passage 111 directly connected to the mist outlet 210. When the fan blade 120 rotates, the small water droplets in the mist passage 111 will not be affected by the airflow of the air duct cavity 130 and change direction, and the connecting end of the mist passage 111 and the mist outlet 210 will not be affected by the airflow of the air duct cavity 130 and change direction. In this way, the small water droplets output by the atomization generator can be accurately transported to the mist outlet 210, and then sprayed out from the mist outlet 210, so as to achieve the effect of humidifying and cooling the environment.

[0071] Of course, in other embodiments, see 1 and Figure 5 A mist pipe 140 is detachably mounted on the air duct housing 110 , and the mist outlet 210 is connected to the output end of the atomization generator through the mist pipe 140 .

[0072] Specifically, see Figure 7 A mounting groove 116 for mounting the mist pipe 140 is provided on the outer wall of the air duct shell 110, a third threaded hole 113 is also provided on the outer wall of the air duct shell 110, and a fourth threaded hole 141 is provided on the mist pipe 140. The fourth threaded hole 141 on the mist pipe 140 is connected to the third threaded hole 113 on the outer wall of the air duct shell 110 by screws, thereby realizing the fixed installation of the mist pipe 140.

[0073] In this way, the mist pipe 140 can be easily disassembled, which makes maintenance and replacement of the mist pipe 140 convenient.

[0074] Also, see Figure 5 The outer wall of the air duct shell 110 is also covered with a decorative shell 150, which improves the structural strength of the air duct shell 110 and plays a decorative role.

[0075] See also Figure 2 and Figure 3 The fan head further includes an atomizing nozzle 300 , which is installed at the mist outlet 210 .

[0076] It can be understood that the atomizing nozzle 300 is connected to the output end of the atomizing generator.

[0077] The atomizing nozzle 300 can spray the water droplets delivered by the atomizing generator in the form of water mist. The specific structure and working principle of the atomizing nozzle 300 are prior art and will not be described in detail here.

[0078] See also Figure 1 and Figure 5 The fan head further includes an air inlet net 400 , which is detachably covered on the air inlet side of the air duct cavity 130 .

[0079] Specifically, see Figure 6 A card slot 114 is provided at the edge of the air duct shell 110, and a screw button 410 is provided at the edge of the air inlet net 400. The screw button 410 of the air inlet net 400 is inserted into the card slot 114 of the air duct shell 110, so as to realize the fixed assembly of the air inlet net 400 and facilitate the disassembly, assembly and cleaning of the air inlet net 400.

[0080] In addition, see Figure 5 The fan head further includes a filter 500, which is disposed between the air inlet net 400 and the air inlet side of the air duct cavity 130. It can be understood that the filter 500 plays a role in filtering impurities in the air, making the air entering the air duct cavity 130 purer.

[0081] Specifically, see Figure 5 and Figure 6 An annular groove 115 is provided at the edge of the air duct shell 110, and the filter 500 can be clamped in the annular groove 115 of the air duct shell 110, so as to realize the fixed assembly of the filter 500 and facilitate the disassembly, assembly and replacement of the filter 500.

[0082] Also, see Figure 1 and Figure 8 The embodiment of the present application also provides an atomizing fan, which includes a base 600, a fan head and an atomizing generator.

[0083] The fan head is detachably mounted on the base 600 , the atomizer generator is mounted inside the base 600 , and the atomizer generator is connected to the mist outlet 210 through a pipeline.

[0084] Specifically, the base 600 includes a base 610, a telescopic tube 620 and a bracket 630. The telescopic tube 620 is mounted on the base 610, the bracket 630 is mounted on the top of the telescopic tube 620, and the air duct housing 110 of the fan head is rotatably mounted on the bracket 630 to achieve the shaking function of the fan head as a whole. The atomizer generator is mounted inside the bracket 630, and the atomizer generator is also connected to the mist outlet 210 through a pipe inside the bracket 630, thereby enhancing the structural integrity of the atomizer fan.

[0085] It is understandable that the telescopic tube 620 can realize the overall lifting and lowering adjustment of the fan head to meet user needs.

[0086] It is not difficult to understand that the atomizing fan of the embodiment of the present application is equipped with the above-mentioned fan head, and therefore, it also has the same technical effect brought by the above-mentioned fan head, that is, it can reduce the probability of mist being sucked into the air duct cavity 130, thereby eliminating the phenomenon of condensation at the air outlet net 200 caused by the mist impacting the air outlet net 200, effectively solving the problem of condensation at the air outlet net 200, eliminating safety and quality risks, and improving user experience.

[0087] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
