Description

TECHNICAL FIELD

[0001] The utility model relates to hair dryer technical field especially is related to a detachable electric hair dryer. BACKGROUND

[0002] Hair dryer, also known as hair dryer, is a kind of small household appliance commonly seen in our daily life. Its main function is to drive fan blade rotation by motor, and wind power is generated, which is heated by electric heating element, to form hot air, for quickly blowing dry hair, blowing dry objects, etc. In order to obtain strong wind power, and improve the blowing experience and its use safety, the current hair dryer is mostly Dyson type hair dryer, which is mainly composed of high-efficiency motor, air channel, small fan and nozzle. The motor is the power source for driving the fan blade to rotate, and the handle part as the air channel is responsible for guiding the air flow, and the small fan blows the air to the nozzle, and the nozzle is responsible for blowing the air to the hair at high speed. Dyson type hair dryer does not rely on the rear end air inlet of the air cylinder, so the rear end is mostly sealed by a cover. The current cover is mostly connected by bolts or buckles. The bolt connection is not convenient to disassemble, and the buckle is pulled up when disassembled, which can easily cause the buckle to break, so it needs to be improved. SUMMARY

[0003] Therefore, it is necessary to provide a detachable electric hair dryer aiming at the above problems.

[0005] Preferably, a convex point is arranged in the clamping position, and a recess is arranged on the surface of the protrusion corresponding to the convex point.

[0006] Preferably, a sliding strip is arranged on one side of the protrusion facing the port of the rear end of the cylinder.

[0007] Preferably, the number of protrusions is four, and they are evenly spaced around the central axis of the cylinder, and the number of clamping grooves is four.

[0008] The utility model has the advantages that when the cover is screwed to the rear end of the cylinder, the cover can be clamped by the cooperation of the clamping groove and the protrusion, the clamping structure is firm and stable, and is not easy to loosen, and no buckle structure is needed, so that damage during disassembly is avoided, and the user's use cost is reduced.

It is to be understood that the terms "consisting of" and "consisting essentially of" are to be construed as closed terms (i.e., meaning "consisting of only the elements specifically listed").

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in this description, the singular forms "a", "an", and "the" include plural references unless the context clearly dictates otherwise. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0015] As Figures 1-3As shown, a detachable electric hair dryer, comprising a barrel 1 and a handle part 2, the barrel 1 and the handle part 2 are connected to form a T shape, the rear end of the barrel 1 is detachably provided with a cover 3, the inner ring 31 of the cover 3 is provided with a plurality of protrusions 11, the inner ring 31 of the cover 3 is provided with a plurality of clamping grooves 32 corresponding to the protrusions 11, the protrusions 11 are correspondingly clamped in the clamping grooves 32, the clamping grooves 32 comprise an outlet position 321 and a clamping position 322, the outlet position 321 is arranged at the ring opening of the inner ring 31, the clamping position 322 is communicated with the outlet position 321, the outlet position 321 is used to guide the protrusions 11 into the clamping position 322. Specifically, in this embodiment, the barrel 1 and the handle part 2 are communicated, so that the fan in the barrel 1 can draw air from the outside through the handle part 2, and then blow out from the front end of the barrel 1 after pressurization, completing the blowing process. In order to avoid air entering the rear end of the barrel 1, we use the cover 3 to block it, and the cover 3 is detachable, which is convenient for disassembling the cover 3 to maintain the fan in the barrel 1. The side of the cover 3 facing the barrel 1 is provided with an inner ring 31, the inner ring 31 is used to insert into the barrel 1, and a plurality of clamping grooves 32 are arranged on the outer ring surface of the inner ring 31, the clamping grooves 32 are matched with the protrusions 11 in the barrel 1 one by one. The clamping grooves 32 comprise an outlet position 321 and a clamping position 322, when clamping, the user rotates and presses the cover 3, when the protrusions 11 are opposite to the outlet position 321, they can be automatically clamped into the outlet position 321, at this time, the user continues to rotate the cover 3, so that the protrusions 11 enter the clamping position 322 from the outlet position 321, avoiding relying only on the elastic extrusion of the cover 3 and the barrel 1, the cover 3 is easy to separate from the rear end of the barrel 1. The use of outlet position 321 and clamping position 322 can firmly lock the protrusions 11, so that the cover 3 and the barrel 1 are not easy to separate.

[0016] As shown, Figures 2-3 The clamping position 322 is provided with a protruding point 3221, and the surface of the protrusion 11 is provided with a recess 111 corresponding to the protruding point 3221. Specifically, in this embodiment, the protruding point 3221 and the recess 111 cooperate to limit the position, avoid loosening and reverse rotation of the cover 3.

[0017] As shown, Figure 3 The protrusions 11 are provided with a sliding strip 112 on the side facing the rear end port of the barrel 1. Specifically, when the user screws the cover 3 into the rear end of the barrel 1, because the sliding strip 112 is arranged near the rear end port of the barrel 1, it can guide the inner ring 31 of the cover 3 and extrude it slightly, making it easier to clamp the clamping grooves 32 and the protrusions 11 when rotating.

[0018] Specifically, the number of protrusions 11 is four, which are evenly spaced around the central axis of the barrel 1, and the number of clamping grooves 32 is four.

[0019] The above embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
