Description

Technical Field

[0001] The invention relates to the technical field of hair dryer equipment, and in particular to a semiconductor ion wind hair dryer. Background Art

[0002] With the improvement of living standards and the continuous advancement of science and technology, people need smarter and more energy-efficient hair dryers. In daily life, hair dryers have become an indispensable household item in most households, mainly used for drying hair and styling hair. They can also be used for local drying, heating, and physical therapy in laboratories, physical therapy rooms, and art studios.

[0003] Existing hair dryers typically consist of a heating wire, a mechanical fan, and a control motherboard. Traditional fans mechanically generate airflow, resulting in noise and vibration during operation. When the hot air setting is selected, the heating wire takes time to generate heat, and the air blown out by the fan is heated by the heating wire to form hot air. However, switching to the cold air setting requires time for the heating wire to cool, so the air blown out of the outlet still contains heat. Furthermore, the high temperature of the hot air setting can reduce the self-heating performance of the control motherboard.

[0004] Furthermore, the hot air from existing hair dryers is too dry, making hair frizzy and dry. Hair dryers also lack constant temperature control, which can easily damage hair. Drying hair also requires using a comb, which can easily generate static electricity, which can cause hair to become deformed, bent, or curled.

[0005] Therefore, the market demand is in urgent need of a hair dryer that can switch between hot and cold air and eliminate static electricity. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a semiconductor ion wind hair dryer, which can achieve switching between hot and cold air and eliminate static electricity.

[0014] As described above, the semiconductor ion wind hair dryer, further, the switching path component includes a rotatable quarter-spherical baffle and a fixed circular baffle, the rotatable quarter-spherical baffle is fixedly connected to the connection between the plug-in handle and the blowpipe by a fixed rotating shaft, the fixed rotating shaft signal is connected to the control circuit board, the fixed circular baffle is bonded above the quarter-spherical baffle, and the fixed circular baffle has an annular area that blocks and covers the hot air channel.

[0015] The semiconductor ion wind blower as described above, further, the rotation angle of the fixed shaft is 90 degrees.

[0016] As described above, the semiconductor ion wind hair dryer further has a button on the plug-in handle, and the button signal is connected to a control circuit board.

[0038] See also Figures 1 to 6 The present invention provides a semiconductor ion wind hair dryer, which may include: a blow tube and a plug-in handle, wherein the blow tube includes an outer cylinder 3 and an inner cylinder 4 arranged inside the outer cylinder 3, the annular space between the outer cylinder 3 and the inner cylinder 4 forms a hot air channel, and the space inside the inner cylinder 4 forms a cold air channel, the inner wall of the outer cylinder 3 is provided with a first thermoelectric cooling chip 31, the heating surface of the first thermoelectric cooling chip 31 faces the hot air channel, and the inner wall of the inner cylinder 4 is provided with a second thermoelectric cooling chip 41, the heating surface of the second thermoelectric cooling chip 41 faces the hot air channel, and the cooling surface faces the cold air channel; one end of the plug-in handle is connected to the blow tube and a switching path component is provided at the connection, an ion wind generating unit is provided inside the plug-in handle, the ion wind generating unit is used to generate ion wind, and the switching path component is used to control the ion wind to lead to the hot air channel or the cold air channel.

[0039] Specifically, the outer cylinder 3 and the inner cylinder 4 of the embodiment of the present invention are both provided with thermoelectric cooling chips. Through the use of the thermoelectric cooling chips, the hot air temperature of the air outlet of the outer cylinder 3 and the cold air temperature of the air outlet of the inner cylinder 4 can be effectively regulated. Compared with the traditional hair dryer, it can achieve the switching between cold and hot air in a short time. At the same time, the embodiment of the present invention generates ion wind through the ion wind generating unit, which has the advantages of low noise and no static electricity compared with the traditional hair dryer. It can be understood that the thermoelectric cooling core of the embodiment of the present invention utilizes the Peltier effect of semiconductor materials. When direct current passes through a galvanic couple formed by two different semiconductor materials in series, heat can be absorbed and released at both ends of the galvanic couple respectively.

[0040] See again Figure 1-Figure 2 , Figure 1 and Figure 2 A semiconductor ion wind hair dryer is presented. It may include a blow tube and a plug-in handle. The blow tube comprises an outer body 3, an inner body 4, and a switching path. The outer body 3 is provided with a handle slot and a button 10. A first thermoelectric cooling chip 31 is housed within the outer body 3, while a second thermoelectric cooling chip 41 is housed within the inner body 4. The switching path consists of a fixed circular baffle 6 and a rotatable quarter-spherical baffle 5, positioned at the junction of the plug-in handle and the blow tube. The plug-in handle is equipped with a mains power connector. An ion wind generating unit is housed within the plug-in handle. The ion wind generating unit includes an electrode holder 12, on which are arranged several transmitting electrode pins 13 electrically connected to a high-voltage power supply. A receiving electrode 11 is located above the transmitting electrode pins 13. In this embodiment, thermoelectric cooling technology enables the hair dryer to quickly switch between hot and cold air. Corona discharge from the ion wind generating unit also eliminates static electricity generated by hair. Compared to traditional hair dryers, this device reduces noise and energy consumption during use.

[0041] See also Figure 4 In some embodiments, the cold end face of the first thermoelectric cooling chip 31 in the outer cylinder 3 faces outward, and the hot end face faces the inner hot air channel. The hot end face of the second thermoelectric cooling chip 41 in the inner cylinder 4 faces the outer hot air channel, and the cold end face faces the inner cold air channel. The arrangement of the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 can heat the hot air channel of the outer cylinder 3 and cool the cold air channel of the inner cylinder 4, thereby ensuring that the air outlet of the outer cylinder 3 blows hot air and the air outlet of the inner cylinder 4 blows cold air, thereby effectively reducing energy consumption and achieving constant temperature air outlet. For example, the thickness of the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 can both be 5 mm, and the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 are both electrically connected to a low-voltage DC power supply.

[0042] See again Figure 1-Figure 2 In some embodiments, a button 10 is provided on the plug-in handle. The button 10 is signal-connected to the control circuit board 7. The button 10 may include a power switch, a cold air blocker, and a hot air blocker. The power switch is used to turn the entire device on and off; the cold air blocker is used to allow the inner cylinder 4 to blow out cold air; and the hot air blocker is used to allow the outer cylinder 3 to blow out hot air.

[0043] See also Figure 5In some embodiments, the switching path member includes a rotatable quarter-spherical baffle 5 and a fixed circular baffle 6. The rotatable quarter-spherical baffle 5 is fixedly connected to the connection between the plug-in handle and the blowpipe by a fixed shaft. The fixed shaft is signal-connected to a control circuit board 7. The fixed circular baffle 6 is bonded to the top of the quarter-spherical baffle and has an annular area that blocks and covers the hot air passage. In this embodiment, the rotation of the quarter-spherical baffle is controlled by the hot and cold air settings. When the hot air blocking button 10 is engaged, the quarter-spherical baffle directs air into the hot air passage of the outer cylinder 3. When the cold air blocking button 10 is engaged, the quarter-spherical baffle directs air into the cold air passage of the inner cylinder 4. By manipulating the spherical baffle with the button 10, the hot and cold air passages can be switched, achieving a quick exchange of hot and cold air. Preferably, the radius of the rotatable quarter-spherical baffle 5 is 20 mm, and the fixed shaft has a rotation angle of 90 degrees.

[0044] See also Figure 3 In some embodiments, an ion wind generating unit is used to generate ion wind, which can be composed of a two-stage pin-fin structure. The two-stage pin-fin structure is arranged in an upper and lower array inside the plug-in handle. The emitting electrode pins 13 are fixed to the electrode holder 12 in a horizontal cross array. In this embodiment, the ion wind generating unit uses corona discharge to eliminate static electricity generated by hair, and this structural arrangement can increase the air output and allow the wind to enter the air outlet duct of the outer cylinder 3 or the air outlet duct of the inner cylinder 4 along the inside of the plug-in handle. In addition, the ion wind generating unit has the advantages of low noise and no static electricity generation. The ion wind generating unit has a certain sterilization function, which can improve the practicality of the equipment. For example, the length of the emitting electrode pin 13 is 10 mm. The diameter of the electrode holder 12 is 40 mm. The diameter of the fin is 40 mm. The vertical distance between the emitting electrode pin 13 and the fin of the receiving electrode 11 is 10 mm. The vertical distance between a single pin-fin ion wind generating unit in the two-stage pin-fin structure is 30 mm. The vertical distance between the two-stage needle-fin structure and the barrel is 50 mm. The emitter electrode needle 13 is electrically connected to a high voltage power supply.

[0045] In the above embodiment, the surface of the emitting electrode needle 13 is further coated with a graphene coating. Specifically, by coating the surface of the emitting electrode needle 13 with the graphene coating, oxidation of the emitting electrode needle 13 during operation can be prevented, which would reduce the air output.

[0046] In some embodiments, the handle 1 of the ion wind hair dryer has a diameter of 45 mm and a length of 200 mm. The outer diameter of the outer cylinder 3 of the ion wind hair dryer is 80 mm, and the inner diameter of the outer cylinder 3 of the ion wind hair dryer is 70 mm. The outer diameter of the inner cylinder 4 of the ion wind hair dryer is 40 mm, and the inner diameter of the inner cylinder 4 of the ion wind hair dryer is 30 mm. The length of the inner cylinder 4 of the ion wind hair dryer is 40 mm, and the length of the outer cylinder 3 is 100 mm.

[0047] In certain embodiments, a temperature sensor 8 is provided at the air outlet of the outer barrel 3, and its signal is connected to the control circuit board 7. In this embodiment, the temperature sensor 8 and the control circuit board 7 constitute a constant temperature control system, which enables constant temperature control of the hot air. Compared with existing technologies, this constant temperature control system can regulate the outlet temperature of the hot air from the outlet duct, speeding up hair drying while preventing hair damage from high temperatures and effectively reducing energy consumption.

[0048] In the above embodiment, further, the air outlet of the blow tube is further provided with a flow balancing film 9. Specifically, by providing the flow balancing film 9 at the air outlet of the blow tube, the wind blown out by the hair dryer can be made more uniform and stable.

[0049] In order to better understand the present invention, the present invention is described below through specific examples.

[0050] Example 1:

[0051] When the hair dryer is in the OFF position, the two-stage needle-fin ion wind generating unit including the receiving electrode 11, the electrode bracket 12, the transmitting electrode needle 13, the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 are all in the closed state.

[0052] Example 2:

[0053] When the hair dryer cord 2 is connected to a power source and the hair dryer is in the cold air mode, the electrode holder 12 of the bipolar needle-fin ion wind generating unit is connected to a high-voltage power source. The tip of the emitting electrode needle 13 ionizes the air within the hair dryer handle 1, generating charged particles. Under the influence of the electric field, these charged particles are accelerated toward the receiving electrode 11, where they collide with air molecules, causing fluid motion and generating ion wind. The tip of the emitting electrode needle 13 also generates negatively charged particles, which disinfect bacteria and microorganisms in the ion wind and eliminate particles generated during hair drying, thereby eliminating static electricity. Simultaneously, a quarter-spherical baffle rotates to the front end of the handle 1, cooperating with the fixed circular baffle 6 to block the ion wind from entering the hot air passage of the outer cylinder 3, allowing the ion wind to enter the cold air passage of the inner cylinder 4 and be blown out through the cold air passage of the inner cylinder 4. Simultaneously, the second thermoelectric cooling chip 41 of the inner cylinder 4 is connected to a low-voltage power source, and its inward-facing cold end surface cools the ion wind in the cold air passage of the inner cylinder 4. Finally, the cold air is blown out from the air outlet of the inner cylinder 4 and passes through the flow-equalizing membrane 9 to achieve uniform air discharge, completing the cold air blowing process of the hair dryer.

[0054] Example 3:

[0055] When the hair dryer wire 2 is connected to the power supply and the hair dryer is in the hot air gear, the electrode bracket 12 of the two-pole needle-fin ion wind generating unit is connected to the high-voltage power supply, and the tip of the emitting electrode needle 13 will ionize the air in the hair dryer handle 1, generating charged particles. Under the action of the electric field, the charged particles are accelerated to move toward the receiving electrode 11, and at the same time collide with air molecules to cause fluid movement, generating ion wind. The tip of the emitting electrode needle 13 electrode will also produce negatively charged particles, which will disinfect bacteria, microorganisms, etc. in the ion wind, and eliminate the particles generated when blowing hair to achieve the purpose of eliminating static electricity. At the same time, the quarter-spherical baffle rotates to the rear end of the handle 1, and cooperates with the fixed circular baffle 6 to block the ion wind from entering the cold air channel of the inner cylinder 4, so that the ion wind enters the hot air channel of the outer cylinder 3 and is blown out from the hot air channel of the outer cylinder 3. At the same time, the first thermoelectric cooling chip 31 of the outer cylinder 3 and the second thermoelectric cooling chip 41 of the inner cylinder 4 are connected to a low-voltage power supply. The outward-facing hot end surface of the second thermoelectric cooling chip 41 of the inner cylinder 4 and the inward-facing hot end surface of the first thermoelectric cooling chip 31 of the outer cylinder 3 heat the ionized air in the channel of the outer cylinder 3. When the hot air passes through the air outlet, the temperature sensor 8 detects the current temperature of the air being blown out and transmits the data to the control circuit board 7. If the current air temperature is below 34°C, the first and second thermoelectric cooling chips 31 and 41 continue to heat the ionized air. If the current air temperature is above 42°C, the first and second thermoelectric cooling chips 31 and 41 stop heating the ionized air, achieving a constant temperature control effect on the hot air. Finally, the hot air is blown out of the hot air channel outlet of the outer cylinder 3 and passes through the flow equalizing membrane 9 for uniform air discharge, completing the hair dryer's hot air setting process.
