Description

[Technical field]

[0001] The present invention relates to the technical field of hair dryer devices, and more particularly to semiconductor ion wind hair dryers. [Background technology]

[0002] With the improvement of living standards and the continuous progress of science and technology, mankind needs smarter and more energy-saving hair dryers. In daily life, hair dryers have become an indispensable household item for many households, mainly used for drying hair and styling hairstyles, and also used for local drying, heating, physical therapy and other purposes in laboratories, physiotherapy rooms, art studios, etc.

[0003] Existing hair dryers usually include a heating wire, a mechanical fan and a control motherboard. The conventional fan adopts a mechanical method to form an air flow, so noise and vibration are generated when the hair dryer is in operation. When the hot air gear is selected, it takes a certain time for the heating wire to generate heat, and the air blown out by the fan is heated by the heating wire and becomes hot air. However, when switching to the cold air gear, it takes a certain time for the heating wire to cool down, so the air blown out from the air outlet still has heat. At the same time, the high temperature of the hot air gear reduces the self-heating performance of the control motherboard.

[0004] In addition, the hot air blown out of conventional hair dryers can dry out hair too much, causing it to become brittle and dry, and at the same time, hair dryers that cannot control the temperature can easily damage hair.In addition, it is unavoidable to use a comb when drying hair, which can easily generate static electricity in the hair, and the static electricity can cause hair to deform, bend, or lift up.

[0005] Therefore, there is a desperate need for a hair dryer that can switch between hot and cold air and remove static electricity. Summary of the Invention [Problem to be solved by the invention]

[0030] 4, in some embodiments, the surface of the cooling end of the first thermoelectric cooling chip 31 in the outer cylinder 3 faces the outside, and the heating surface faces the inner hot air passage. The surface of the heating end of the second thermoelectric cooling chip 41 in the inner cylinder 4 faces the outer hot air passage, and the surface of the cooling end faces the inner cold air passage. The arrangement of the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 can heat the hot air passage of the outer cylinder 3 and cool the cold air passage of the inner cylinder 4, thereby ensuring that hot air is blown out from the air blower of the outer cylinder 3 and cold air is blown out from the air blower of the inner cylinder 4, effectively reducing energy consumption and realizing constant temperature air blowing. Exemplarily, the thickness of each of the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 is 5 mm, and both the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 are electrically connected to a low-voltage DC power source.

[0031] 1 and 2 again, in some embodiments, the plug-in handle is provided with a button 10, which is signal-connected to the control circuit board 7, and the button 10 may include a power switch, a cold air gear, and a hot air gear. Here, the power switch is used to turn on or off the entire device, the cold air gear is used to blow cold air from the air blower tact of the inner cylinder 4, and the hot air gear is used to blow hot air from the air blower tact of the outer cylinder 3.

Preferably, the radius of the rotatable quarter-spherical baffle 5 is 20 mm. The rotation angle of the fixed rotation axis is 90 degrees.

[0033] Referring to FIG. 3, in some embodiments, the ion wind generating unit is used to generate ion wind and can be configured with a two-stage pin-fin structure, and the two-stage pin-fin structure is arranged vertically inside the plug-in handle. The emitter electrode needle 13 is fixed to the emitter electrode bracket 12 in a horizontal cross arrangement. In this embodiment, the ion wind generating unit can eliminate static electricity generated on the hair by using corona discharge, and the arrangement of the structure can improve the amount of air blowing, and can realize the air blowing into the air blowing tact of the outer tube or the air blowing tact of the inner tube 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, and the ion wind generator unit has a certain sterilization function, which can improve the practicality of the device. For example, the length of the emitter electrode needle 13 is 10 mm. The diameter of the electrode brad 12 is 40 mm. The diameter of the fin is 40 mm. The vertical distance between the emitter electrode needle 13 and the fin of the receiving electrode 11 is 10 mm. The vertical distance between the single pin fin ion wind generating units in the two-stage pin-fin structure is 30 mm. The vertical distance from the two-stage pin-fin structure to the cylinder is 50 mm. The emitter electrode needle 13 is electrically connected to a high voltage power supply.

[0034] In the above embodiment, furthermore, a graphene coating is applied to the surface of the emitter electrode needle 13. Specifically, by applying a graphene coating to the surface of the emitter electrode needle 13, it is possible to prevent the emitter electrode needle 13 from being oxidized in the operating state and thus preventing a decrease in the amount of air blown.

[0035] In some embodiments, the diameter of the ionic wind hair dryer handle 1 is 45 mm, and the length of the hair dryer handle 1 is 200 mm.

The outer diameter of the inner cylinder 4 of the ionic wind hair dryer is 40 mm, and the inner diameter of the inner cylinder 4 of the ionic wind hair dryer is 30 mm. The length of the inner cylinder 4 of the ionic wind hair dryer is 40 mm, and the length of the outer cylinder 3 is 100 mm.

[0036] In some embodiments, a temperature sensor 8 is installed at the air outlet of the outer cylinder 3, and the temperature sensor 8 is signal-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 can control the hot air to a constant temperature. Compared with existing technologies, the constant temperature control system can adjust the hot air temperature of the outer air outlet, speed up hair drying, and at the same time prevent hair damage caused by high temperatures, effectively reducing energy consumption.

[0037] In the above embodiment, the air outlet of the blower tube is further provided with an air equalizing film 9. Specifically, by providing the air equalizing film 9 at the air outlet of the blower tube, the air blown out from the hair dryer can be made more uniform and stable.

[0038] In order that the invention may be better understood, it will now be described by way of specific examples.

[0039] Example 1 When the hair dryer is in off gear, the two-stage pin-fin ion wind generating unit includes a receiving electrode 11, an electrode brad 12, an emitter electrode needle 13, a first thermoelectric cooling chip 31 and a second thermoelectric cooling chip 41, all of which are in off state.

[0040] Example 2 When the hair dryer cord 2 is connected to the power source and the hair dryer is in the cold air gear, the electrode brad 12 of the two-stage pin-fin ion wind generating unit is connected to the high voltage power source, and the tip of the emitter electrode needle 13 ionizes the air in the handle 1 of the hair dryer to generate charged particles, which are accelerated under the action of the electric field and move toward the receiving electrode 11, while colliding with air molecules to cause fluid motion and generate ion wind. In addition, negatively charged particles are generated from the tip of the emitter electrode needle 13, which kills bacteria and microorganisms contained in the ion wind, and achieves the purpose of removing particles generated when blowing hair and removing static electricity. At the same time, the quarter-spherical baffle rotates to the front end of the handle 1 and cooperates with the fixed circular surface baffle 6 to prevent the ion wind from entering the hot air passage of the outer cylinder 3, so that the ion wind enters the cold air passage of the inner cylinder 4 and is blown out from the cold air passage of the inner cylinder 4.

[0041] Example 3 When the hair dryer cord 2 is connected to the power source and the hair dryer is in hot air gear, the electrode brad 12 of the two-stage pin-fin ion wind generating unit is connected to the high voltage power source, and the tip of the emitter electrode needle 13 ionizes the air in the handle 1 of the hair dryer to generate charged particles, which are accelerated under the action of the electric field and move toward the receiving electrode 11, while colliding with air molecules to cause fluid motion and generate ion wind. In addition, negatively charged particles are generated from the tip of the emitter electrode needle 13, which kills bacteria and microorganisms contained in the ion wind, and achieves the purpose of removing particles generated when blowing hair and removing 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 surface baffle 6 to prevent the ion wind from entering the cold air passage of the inner cylinder 4, so that the ion wind enters the hot air passage of the outer cylinder 3 and is blown out from the hot air passage 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, and the surface of the outward heating end of the second thermoelectric cooling chip 41 of the inner cylinder 4 and the surface of the inward heating end of the first thermoelectric cooling chip 31 of the outer cylinder 3 realize the heating effect on the ion wind in the passage of the outer cylinder 3. When the hot air passes through the air outlet, the temperature sensor 8 detects the temperature of the air currently being blown out and transfers the data to the control circuit board 7. If the temperature of the current air is lower than 34°C, the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 continue to heat the ion wind, and if the temperature of the current air is higher than 42°C, the first thermoelectric cooling chip 31 and the second thermoelectric cooling chip 41 stop heating the ion wind, thereby achieving the effect of controlling the hot air at a constant temperature. Finally, the hot air is blown out from the air outlet of the hot air passage of the outer cylinder 3 and passes through the uniform flow film 9 to become an even air volume, completing the blowing process of the hot air gear of the hair dryer.
