Technical Field

[0001] The utility model relates to the technical field of hair dryer structures, in particular to a hair dryer structure with side air intake. Background Art

[0002] A hair dryer is composed of a group of electric heating wires and a small high-speed fan. When powered on, the electric heating wires will generate heat, and the wind blown by the fan will become hot air after passing through the electric heating wires. Hair dryers are mainly used for hair drying and shaping, but can also be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, and art. According to the type of motor it uses, it can be divided into AC series-excited type, AC shaded-pole type, and DC permanent magnet type.

[0003] The main working principle of a hair dryer is to draw outside air into the interior through the air intake fan at the rear end thereof, and then heat this air through the heating wire and blow it out to achieve the purpose of drying. However, the air inlet of existing hair dryers is often directly opened at the rear end of the hair dryer's wind tube, which has a small area and a small air intake volume. It is also easily clogged by dust, and the effect of the hair dryer will decrease after long-term use.

[0004] Therefore, how to increase the air intake of the hair dryer and prevent the air inlet from being blocked is a technical problem that needs to be urgently solved in the industry. Utility Model Content

[0019] It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Refer to Figures 1 - 3, an embodiment of the present utility model is proposed. A hair dryer structure with side air intake includes a main cylinder body 1. A grip 2 is vertically and fixedly connected to the bottom end of the main cylinder body 1. A nozzle 3 is fixedly connected to the front end of the main cylinder body 1. A plurality of air inlets 4 are formed through the rear part of the outer surface of the main cylinder body 1. A dust-proof cylinder 7 with a closed rear end is detachably installed on the rear part of the outer surface of the main cylinder body 1. When the dust-proof cylinder 7 is installed on the outer surface of the main cylinder body 1, all the air inlets 4 are located inside the dust-proof cylinder 7;

[0021] An external thread 9 is provided on the outer surface of the main cylinder body 1 and in front of the plurality of air inlets 4. An internal thread corresponding to and adapted to the external thread 9 is provided at the front end of the inner surface of the dust-proof cylinder 7. The dust-proof cylinder 7 is detachably installed on the outer surface of the main cylinder body 1 through the internal thread.

[0022] The main cylinder body 1, the grip 2 and the nozzle 3 constitute the overall external structure of the device. A control button 12 is provided on the grip 2 to control the start and stop of the device. The plurality of air inlets 4 of the device are arranged on the outer surface of the main cylinder body 1 and are not limited by the cross-sectional area of the main cylinder body 1, so its open area will be larger, thereby increasing the air intake of the device. And the device is also provided with a dust-proof cylinder 7. When the device is not in use, the dust-proof cylinder 7 can be installed on the outer surface of the device. Under the action of the dust-proof cylinder 7, external dust cannot contact the air inlets 4, making it more difficult for the air inlets 4 to be blocked, thereby improving the service life and use effect of the device.

[0023] The dust-proof cylinder 7 is installed on the outer surface of the main cylinder body 1 by means of threaded connection. This connection method is relatively simple and is very suitable for use in this device.

[0024] Furthermore, a first sealing ring 6 is fixedly connected to the outer surface of the main cylinder body 1 and in front of the external thread 9. A second sealing ring 8 is fixedly connected to the front end of the dust-proof cylinder 7. When the dust-proof cylinder 7 is installed on the main cylinder body 1, the first sealing ring 6 and the second sealing ring 8 are in contact.

[0025] When the dust-proof cylinder 7 is installed on the outer surface of the main cylinder body 1, the first sealing ring 6 and the second sealing ring 8 are in contact, further improving the sealing effect of the dust-proof cylinder 7.

[0026] Furthermore, a anti-loss cord 10 is fixedly connected between the rear end surface of the inner cavity of the dust-proof cylinder 7 and the rear end surface of the main cylinder body 1.

[0027] When using the device, it is necessary to remove the dust-proof cylinder 7. The anti-loss cord 10 can prevent the dust-proof cylinder 7 from completely separating from the main cylinder body 1, playing an anti-loss role.

[0028] Furthermore, an installation frame 13 is fixedly connected to the rear end inside the main cylinder body 1. A motor 14 is horizontally and fixedly connected inside the installation frame 13. The rear end of the output shaft of the motor 14 is fixedly connected to an exhaust fan 15.

[0029] The main cylinder 1 is also provided with a heating wire and other structures, which are the same as the structure of the existing hair dryer and will not be described in detail here.

[0030] Furthermore, dustproof nets 5 are fixedly connected inside the plurality of air inlets 4 .

[0031] The dustproof net 5 can play a dustproof effect and can also prevent excessive dust from the outside from entering the interior of the device when the device is used.

[0032] Furthermore, the outer surface of the dustproof cylinder 7 is provided with anti-slip grooves 11 .

[0033] The anti-skid pattern 11 has an anti-skid effect, and can facilitate people to install and remove the dustproof cylinder 7.

[0034] When working, the multiple air inlets 4 of the device are arranged on the outer surface of the main cylinder 1, and will not be limited by the cross-sectional area of ​​the main cylinder 1, so the open area will be larger, thereby increasing the air intake of the device, and the device is also provided with a dustproof cylinder 7. When the device is not in use, the dustproof cylinder 7 can be installed on the outer surface of the device. Under the action of the dustproof cylinder 7, external dust cannot contact with the air inlet 4, and the air inlet 4 is more difficult to be blocked, thereby improving the service life and use effect of the device.

[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
