Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a novel rear-inlet high-speed hair dryer. Background Art

[0002] With the development of society and the improvement of people's living standards, people's requirements for the quality of material life are constantly increasing, and high-speed hair dryers are also a tool used in people's daily lives. Naturally, people's quality requirements for using it are also increasing. Hair dryers are one of the most widely used household appliances among existing home users and consumers, and one of the most popular hairdressing electrical appliances. All existing high-speed hair dryers have handle air intake. Since the air duct has a 90-degree turn, there is a great loss of air volume and electric energy. In order to reduce the loss of air volume and electric energy, the handle air intake is changed to rear air intake. However, at the same time, the following problems arise: the high-speed hair dryer has a small fan diameter, a small wind beam diameter, and the wind flow passes through the middle of the electric heating wire loop, resulting in poor heat dissipation of the electric heating wire and heating of the side wall when the hair dryer is used. For this reason, the utility model proposes a new type of rear air intake high-speed hair dryer with rear air intake to solve the deficiencies and shortcomings of the prior art. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the above-mentioned technology and to provide a novel rear-inlet high-speed hair dryer.

[0004] The technical solution adopted by the utility model is:

[0005] A novel rear-inlet high-speed hair dryer comprises a hair dryer housing, a high-speed fan installed on the rear side of the hair dryer housing through a fixing seat, and a heating element installed on the front side of the hair dryer housing, a fixing element is installed between the high-speed fan and the heating element, and an air guide plate is installed on the fixing element;

[0006] Among them, the fixing part consists of a fixing block and an air guide block, the air guide block is fixedly installed on the rear side of the fixing block, the fixing block is fixedly connected to the inner wall of the hair dryer housing, the edge of the air guide plate abuts against the top of the air guide block, and the air guide plate and the fixed block are connected by fixing screws.

[0007] Preferably, the outer diameter of the air guide plate is half the inner diameter of the hair dryer housing.

[0008] Preferably, the air guide plate is in a spherical crown shape, the rear side of the air guide plate is a protruding surface, and the front side is a flat surface.

[0009] Preferably, the rear end of the high-speed fan is an air inlet, and the front end thereof is an air outlet, and the distance from the center of the outer surface of the air guide plate to the center of the air outlet of the high-speed fan is one quarter of the outer diameter of the air guide plate.

[0010] Preferably, the heating element comprises a heating wire and a mica frame, a mounting groove is provided on the front side of the fixing block, the mica frame is snapped into the mounting groove, and the heating wire is mounted on the mica frame.

[0011] The beneficial effects of the utility model are as follows: the utility model effectively solves the problem of heating of the side wall when the rear-inlet high-speed hair dryer is in use, and by adding the setting of the fixing parts and the air guide plate, the airflow can be dispersed and flow along the inner wall of the hair dryer, which can take away the heat on the heating wire. Not only does the airflow along the inner wall of the hair dryer form a wind curtain, which can effectively play a heat insulation effect and prevent the side wall of the hair dryer from being heated by the heating wire, but also reduces the heat conduction loss; the utility model adds the air guide plate and can also make the wind flow along the inner wall of the hair dryer to the air outlet, which greatly reduces the noise generated by the airflow directly hitting obstacles such as the heating wire and the mica rack, and has significant practicality.

[0017] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0018] like Figure 1-4As shown, a novel rear-inlet high-speed hair dryer comprises a hair dryer housing 001, a high-speed fan 002 installed on the rear side of the hair dryer housing 001 through a fixing seat 004, and a heating element 003 installed on the front side of the hair dryer housing 001, a fixing element 005 is installed between the high-speed fan 002 and the heating element 003, and an air guide plate 006 is installed on the fixing element 005;

[0019] Among them, the fixing part 005 is composed of a fixing block 510 and an air guide block 520, the air guide plate 520 is fixedly installed on the rear side of the fixing block 510, the fixing block 510 is fixedly connected to the inner wall of the hair dryer housing 001, the edge of the air guide plate 006 abuts against the top of the air guide block 520, and the air guide plate 006 and the fixing block 510 are detachably connected by fixing screws 007.

[0020] The further optimization settings of this scheme are: Figure 1-4 As shown, the outer diameter of the air guide plate 006 is half the inner diameter of the hair dryer housing 001. The airflow blown out by the high-speed fan 002 is evenly guided to the inner wall of the hair dryer after encountering the air guide plate 006, and passes between the inner wall of the hair dryer and the heating wire 310, taking away the heat on the heating wire 310, and then outputted from the outlet end of the hair dryer.

[0021] Among them, the outer diameter of the air guide plate 006 in the novel rear-inlet high-speed hair dryer of this embodiment is the same as the outer diameter of the high-speed fan 002, which can ensure that the wind blown out by the high-speed fan 002 can be completely guided out by the air guide plate 006.

[0022] The further optimization settings of this scheme are: Figure 1-4 As shown, the air guide plate 006 is spherical, the rear side of the air guide plate 006 is a protruding surface, and the front side is a plane, which can make the airflow blown out by the high-speed fan 002 be smoothly guided out from the protruding surface, reduce the influence on the wind speed as much as possible, and make the airflow be guided out evenly.

[0023] The further optimization settings of this scheme are: Figure 1-4 As shown, the rear end of the high-speed fan 002 is an air inlet 210, and the front end is an air outlet 220. The distance from the center of the outer surface of the air guide plate 006 to the center of the air outlet 220 of the high-speed fan 002 is one-fourth of the outer diameter of the air guide plate 006. When the distance between the two is too large, the length of the hair dryer increases. When the distance between the two is too small, the airflow blown out by the high-speed fan 002 will be blocked, reducing the final wind speed.

[0024] The further optimization settings of this scheme are: Figure 1-4As shown, the heating element 003 includes a heating wire 310 and a mica frame 320. A mounting groove 511 is opened on the front side of the fixed block 510. The mica frame 320 is snapped into the mounting groove 511. The heating wire 310 is installed on the mica frame 320. The mica frame 320 is cross-shaped. One end of the mica frame 320 is fixedly installed in the mounting groove 511 on the fixed block 510. The radius of the heating wire 310 is larger than the outer diameter of the air guide plate 006. This allows the airflow blown out by the high-speed fan 002 to be guided out through the air guide plate 006, and then the heat on the heating wire 310 can be smoothly taken away.

[0025] The further optimization settings of this scheme are: Figure 1-4 As shown, the air guide plate 006 is installed on the mica frame 320 with a slot, and the mica frame 320 is assembled and the air guide plate 006 is snap-fitted. This allows the airflow blown out by the high-speed fan 002 to be guided out through the air guide plate 006, and then the heat on the heating wire 310 can be smoothly taken away.
