[0002] Since electrohydrodynamic flow was proposed by F. Hauksbee in 1709, this phenomenon of gas flow caused by air ionization due to corona discharge has attracted the attention of scholars around the world. After more than 300 years of hard exploration by countless scholars, its mechanism has been gradually revealed and has been widely used in the fields of flow control, enhanced heat transfer, room temperature drying and power.

[0003] In the field of enhanced heat transfer, ion wind enhanced heat dissipation technology has the advantages of simple structure, flexibility, small size, light weight, no mechanical moving parts, low noise, low power, etc. compared with traditional mechanical fan heat dissipation technology. However, the existing ion wind heat dissipation products on the market are mostly used to dissipate heat for high-end electronic products, and there is no ion wind heat dissipation fan for dissipating heat for people. Therefore, the present invention proposes a household ion wind heat dissipation fan. Summary of the invention

[0004] The embodiment of the present application provides a household ion wind cooling fan, which can improve the air quality in the environment while solving the user's heat dissipation problem.

[0016] Optionally, the atomizer comprises a water tank for providing liquid;

[0017] The spray port of the atomizer is provided with a mist delivery pipeline;

[0018] The mist delivery pipeline is fixedly connected to the first insulating bracket;

[0019] A plurality of mist outlets are arranged on the pipe wall of the mist delivery pipe along the circumferential direction.

[0020] Optionally, the atomizer is a mesh atomizer.

[0021] Optionally, the ion wind generating device further includes an insulating shell;

[0022] The first insulating support and the second insulating support are sequentially and parallelly arranged in the insulating shell from the inside to the outside.

[0023] Optionally, the needle emitter array consists of a plurality of needle emitters.

[0024] Optionally, the needle-shaped emitter comprises a metal needle and a bowl-shaped insulating current-conducting structure;

The ions produced by the corona effect are accelerated under the action of the electric field and collide with neutral molecules in the air to exchange momentum and energy, eventually forming a directional ion wind, thereby solving the problem of heat dissipation for users. At the same time, since the negative electrode corona ion wind contains a large number of negative ions, oxygen molecules and water molecules in the air are most likely to capture the electrons produced by corona discharge to form small-particle negative ions. Studies have shown that negative ions can play a bactericidal role, and ecological-grade small-particle negative ions can improve human health conditions to a certain extent. Therefore, household ion wind cooling fans can not only take away the heat from the human body, but also provide the human body with a steady supply of negative ions, providing users with a healthier air environment.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] The inventors have found that there is currently no ion wind cooling fan for cooling people. Since the ion wind cooling technology requires a relatively high voltage to operate normally, it cannot meet the conditions of general household electricity consumption.

[0042] This application provides an embodiment of a household ion wind cooling fan. Figure 1 to Figure 2 .

[0043] The household ion wind cooling fan in this embodiment includes: a power supply 3, a boost circuit and an ion wind generating device 1; the power supply 3 is electrically connected to the boost circuit; the boost circuit is electrically connected to the ion wind generating device 1; the ion wind generating device 1 includes a first insulating bracket 11 and a second insulating bracket 12; a needle-shaped emitter array 13 is provided on the first insulating bracket 11; a receiving electrode is provided on the second insulating bracket 12; the needle-shaped emitter array 13 is grounded.

[0044] It should be noted that: since the conditions of general household electricity cannot generate ion wind, a power supply 3, a boost circuit and an ion wind generating device 1 are provided, the power supply 3 is electrically connected to the boost circuit, the boost circuit is electrically connected to the ion wind generating device 1, and the voltage of the power supply 3 is boosted to obtain a DC negative high voltage required by the ion wind generating device 1; the ion wind generating device 1 includes a first insulating bracket 11 and a second insulating bracket 12, a needle-shaped emitter array 13 is provided on the first insulating bracket 11, and a receiving electrode is provided on the second insulating bracket 12, the needle-shaped emitter array 13 is grounded, and the emitter is made negative high voltage by grounding the needle-shaped emitter array 13, and the ion wind generating device 1 generates a high-intensity electric field around the emitter to ionize the nearby air to produce a corona discharge phenomenon, The ions generated by the corona effect are accelerated under the action of the electric field and collide with neutral molecules in the air to exchange momentum and energy, eventually forming a directional ion wind, thereby solving the problem of heat dissipation for users. At the same time, since the negative electrode corona ion wind contains a large number of negative ions, the oxygen molecules and water molecules in the air are most likely to capture the electrons generated by corona discharge to form small-particle negative ions. Studies have shown that negative ions can kill bacteria, and ecological-grade small-particle negative ions can improve human health conditions to a certain extent. Therefore, household ion wind cooling fans can not only take away the heat from the human body, but also provide the human body with a steady supply of negative ions, which can kill bacteria, accelerate the degradation of toxic substances such as formaldehyde, and improve air quality, providing users with a healthier air environment.

[0045] Compared with the existing mechanical cooling fans, the household ion wind cooling fan has the characteristics of simple structure, flexibility, small size and light weight, and has higher portability. At the same time, since it has no mechanical parts, low noise and higher comfort in use.

[0046] The above is a first embodiment of a household ion wind cooling fan provided by the embodiment of the present application. The following is a second embodiment of a household ion wind cooling fan provided by the embodiment of the present application. For details, please refer to Figures 1 to 7 .

[0047] The household ion wind cooling fan in this embodiment includes: a power supply 3, a boost circuit and an ion wind generating device 1; the power supply 3 is electrically connected to the boost circuit; the boost circuit is electrically connected to the ion wind generating device 1; the ion wind generating device 1 includes a first insulating bracket 11 and a second insulating bracket 12; the first insulating bracket 11 and the second insulating bracket 12 play a supporting and fixing role; a needle-shaped emitter array 13 is provided on the first insulating bracket 11; a receiving electrode is provided on the second insulating bracket 12; the needle-shaped emitter array 13 is grounded, and the ion wind generating device 1 composed of the needle-shaped emitter array 13 and the receiving electrode continuously provides ion wind when working, which not only dissipates heat for the user, but also improves the air quality of the environment.

[0048] Specifically, it also includes: a column 2, the column 2 is a hollow structure, the power supply 3 and the boost circuit are both arranged in the column 2, and the upper and lower ends of the column 2 are sealed by an upper cover plate 21 and a lower cover plate 22 respectively. It can be understood that: the upper cover plate 21 and the lower cover plate 22 can be a detachable structure, which is convenient for replacement and maintenance of the equipment in the column 2.

[0049] The boost circuit includes a high-frequency oscillation circuit, a transformer and a triple voltage rectifier circuit; the high-frequency oscillation circuit is electrically connected to the transformer; the transformer is electrically connected to the triple voltage rectifier circuit

[0050] Specifically, the high-frequency oscillation circuit can convert the 5V DC voltage generated by the power supply 3 into a high-frequency AC power of about 20kHz, the transformer converts the low-voltage high-frequency AC power generated by the high-frequency oscillation circuit into a high-frequency AC power of about 1000V, and the triple voltage rectifier circuit amplifies and rectifies the high-frequency AC power of about 1000V into a negative DC voltage that can meet the requirements of the ion wind generator, thereby solving the problem that household voltage cannot generate ion wind.

[0051] like Figure 7 As shown, the detailed working process is as follows: when the switch SB of the power supply 3 is pressed, the high-frequency oscillator composed of the transistor VT and the high-frequency transformer TU is powered on, and the 5V DC generated by the power supply 3 is converted into a high-frequency AC of about 20kHz, which is boosted by about 1000V by TU, and then tripled rectified by diodes VD2~VD4 and capacitors C1~C3 to about 3000V, and then added to the ion wind generating device 1. By grounding the emitter (leading out a wire from it and connecting it to the ground wire of the triangle plug), the emitter is made into a negative high voltage, and finally the 5V DC is converted into a 3000V DC that can meet the needs of the ion wind generating device 1.

[0052] It also includes: an atomizer 4 for providing mist for the ion wind cooling fan, which locally humidifies the needle-shaped emitter 7 by adopting atomization technology to increase the relative humidity in the needle-shaped emitter 7 area, and finally achieves the function of reducing the starting voltage of the ion wind generating device 1, which also solves the problem of excessively high operating voltage of the ion wind generating device 1.

[0053] It is understandable that the atomizer 4 can change the humidity of the incoming wind according to user needs, and the evaporation of the water mist in the incoming wind can also absorb a certain amount of heat from the surrounding air to further enhance the heat dissipation performance. In addition, the local high humidity around the needle-shaped emitter 7 can reduce the corona discharge inception voltage, making the ion wind cooling fan safer.

[0054] The atomizer 4 includes a water tank 5 for providing a liquid source for the atomizer 4; a mist delivery pipe 6 is arranged on the spray port of the atomizer 4; the mist delivery pipe 6 is fixedly connected to the first insulating bracket 11; and a plurality of mist outlets 61 are arranged circumferentially on the pipe wall of the mist delivery pipe 6.

[0055] Specifically, Figure 6 As shown, a through hole is provided on the column 2, and the mist delivery pipe 6 passes through the through hole and is fixedly connected to the first insulating bracket 11. The mist delivery pipe 6 is fixedly connected to the through hole, and a plurality of mist outlets 61 are circumferentially provided on the pipe wall of the mist delivery pipe 6, so that the overall structure of the household ion wind cooling fan is more compact, and the mist generated from the atomizer 4 moves toward the needle-shaped emitter 7 under the action of suction to finally realize the humidification function.

[0056] The atomizer 4 is a mesh atomizer, which has the characteristics of a compression atomizer and an ultrasonic atomizer. Its function is to provide small-scale droplets for the ion wind cooling fan and increase the relative humidity around the needle-shaped emitter 7. In addition, the user can manually adjust the atomization amount of the atomizer 4 according to his own needs.

[0057] The ion wind generating device 1 also includes an insulating shell; a first insulating bracket 11 and a second insulating bracket 12 are arranged in parallel in the insulating shell from the inside to the outside. It can be understood that: mesh holes are provided on both sides of the insulating shell to prevent the user's body from contacting the needle-shaped emitter 7 while minimizing the insulating shell's obstruction to the ion wind.

[0058] Specifically, the insulating shell includes a bottom shell 15 and a surface cover 16, which are detachably connected. An opening for passing the mist delivery pipe 6 is provided at the center position of the bottom shell 15, and the mist delivery pipe 6 passes through the opening into the bottom shell 15 and is fixedly connected to the first insulating bracket 11.

[0059] like Figure 4 As shown, the needle emitter array 13 is composed of a plurality of needle emitters 7. The needle emitter array 13 may be a 3×3 square array. Such an arrangement can ensure that the amount of ion wind generated is relatively uniform.

[0060] like Figure 5As shown, the needle-shaped emitter 7 includes a metal needle 71 and a bowl-shaped insulating guide structure 72; the metal needle 71 is fixed at the center position of the bowl-shaped insulating guide structure 72, and the bowl-shaped insulating guide structure 72 is located at the bottom end of the metal needle 71. The bowl-shaped insulating guide structure 72 can change the wind direction of the reverse ion wind, thereby making full use of the kinetic energy of the reverse ion wind to increase the ion wind volume of the ion wind generating device 1 and meet the user's heat dissipation needs.

[0061] like Figure 3 As shown, the receiving electrode is a mesh receiving electrode 14 , and the material of the mesh receiving electrode 14 is copper with high conductivity.

[0062] The power source 3 is a rechargeable battery, specifically, a lithium battery with a battery capacity of 2000 mAh, which can be recharged more than 500 times.

[0063] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
