Detailed Description

in order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.

the first embodiment of the present invention relates to a handle of a hair dryer, as shown in fig. 1, the handle 1 is provided in the hair dryer, and a blower is disposed in the handle 1 and held by a user.

As shown in fig. 1 and 2, the handle 1 includes: handle inner shell 2, the handle outer shell 3 that encircles handle 1, handle inner shell 2 includes: the hair dryer comprises a first inner wall 21, a second inner wall 22 opposite to the first inner wall 21 and a rear body shell 23 which is integrally formed with the first inner wall 21, wherein the second inner wall 22 and the first inner wall 21 are fixedly connected and jointly enclose an air duct 4 of the hair dryer. In this embodiment, the first inner wall 21 and the second inner wall 22 are connected by a bolt, but the first inner wall 21 and the second inner wall 22 may also be connected by other methods, such as a plug connection, and the like. The blower of the hair dryer draws air from the bottom of the handle 1, through the duct 4 into the body and out. If a gap exists between the air duct 4 and the handle shell 3, air can escape from the air duct 4 to the gap between the handle shell 3 and the air duct 4 and overflow out of the handle 1, so that air volume loss blown out by the hair dryer is caused.

the back body casing 23 is formed integrally with the first inner wall 21, part of the back body casing 23 is used for covering the body, the other part of the back body casing 23 covers the second inner wall 22, a containing area 31 is formed between the back body casing 23 and the second inner wall 22, and the switch of the hair dryer is placed in the containing area 31. As can be seen from the above, the wind in the wind tunnel 4 may escape from the accommodating area 31 between the rear body casing 23 and the second inner wall 22 and flow out of the handle 1.

Referring to fig. 3, a part of the rear body casing 23 away from the first inner wall 21 is inserted into the handle casing 3 and protrudes toward the accommodating area 31 to form a protruding portion 231 inserted into the accommodating area 31, and the protruding portion 231 is spaced from the second inner wall 22 and does not contact with the second inner wall. The handle 1 further comprises: and the sealing piece 5 is arranged in the accommodating area 31, and the sealing piece 5 is tightly attached to the second inner wall 22 and the protruding part 231 respectively and used for sealing the accommodating area 31 and preventing the air in the air duct 4 from escaping from the accommodating area 31 to the outside of the hair dryer.

As shown in fig. 4, wherein the sealing member 5 includes: the seal body 51 and at least one lip 52 annularly provided on the peripheral side of the seal body 51 are arranged at equal intervals if the number of the lips 52 is larger than two. In the present embodiment, two lips 52 are provided, but of course, the number of lips 52 may be other, and only two lips are used as an example in the present embodiment, and are not particularly limited.

as shown in fig. 3, the lip 52 includes: an outer ring inclined surface 521, an inner ring inclined surface 522 opposite to the outer ring inclined surface 521, the outer ring inclined surface 521 connected with the outer surface of the seal main body 51 and extending obliquely toward the direction of the rear body casing 23. The inner ring slope 522 is also connected to the outer surface of the seal body 51 and is inclined in the same direction as the outer ring slope 521, and the inner ring slope 522 is located below the outer ring slope 521. While the inner ring chamfer 522 forms a space with the outer surface of the seal body 51, which is a tapered space. It should be noted that the lip 52 is a flexible body, and the outer annular inclined surface 521 and the inner annular inclined surface 522 are both arranged obliquely, so that the sealing member 5 can be conveniently taken out from the accommodating area 31 to perform maintenance on the switch and the motor in the accommodating area 31.

The handle 1 in this embodiment seals the accommodating area 31 between the second inner wall 22 and the handle housing 3 through the arrangement of the sealing member 5, so as to prevent air in the air duct 4 from entering the accommodating area 31 through a gap between the second inner wall 22 and the protruding portion 231 and escaping from the handle 1, which causes the air volume blown out by the hair dryer to be small.

A second embodiment of the invention relates to a hair dryer comprising a front body and a handle 1 as in the first embodiment. Wherein, as shown in fig. 2, the precursor comprises: the front body inner shell and the front body outer shell surrounding the front body inner shell are detachably connected, and part of the front body inner shell is inserted into the back body outer shell 23 and clamped with the back body outer shell 23. The air in the air duct 4 enters the front body from the air duct 4, and is blown out of the front body to dry the hair of the user.

Notably, the hair dryer further comprises: the back body inner shell is arranged in the back body outer shell 23 and detachably connected with the back body outer shell 23, the back body inner shell and the back body outer shell 23 are mutually separated to form an annular space 6, the annular space 6 is communicated with the air duct 4, and the control circuit board 8 of the hair dryer is arranged in the annular space 6. When the hair dryer works, most of air in the air channel 4 is blown out from the front body, a small part of air enters the annular space 6 communicated with the air channel 4, flowing air can dissipate heat of the control circuit board 8 in the annular space 6, normal operation of the hair dryer is guaranteed, air in the air channel 4 is fully utilized, a heat dissipation device does not need to be arranged, and resources are saved.

As shown in fig. 2 and 3, the second inner wall 22 is partially separated from the handle housing 3 to form a mounting area 32 communicated with the accommodating area 31, the switch component 7 and the motor component are mounted in the mounting area 32, the switch component 7 is used for triggering when being pressed by a user, the switch component 7 is electrically connected with the control circuit board 8 through a first conducting wire, and the motor component is electrically connected with the control circuit board 8 through a second conducting wire. Since the seal 5 seals between the second inner wall 22 and the projection 231, the seal main body 51 of the seal 5 is opened with a first wire guide 511 and a second wire guide 512. The first wire guide 511 and the second wire guide 512 both penetrate the sealing body 51, and the first wire guide 511 is used for guiding the first guide from the mounting area 32 to the annular space 6, so as to electrically connect the switch assembly 7 with the control circuit board 8. The second conductor is used to guide the second guide from the mounting area 32 to the annular space 6, enabling the electrical connection of the motor assembly to the control circuit board 8.

It should be noted that, as shown in fig. 4, a through hole 513 is further formed on the sealing member main body 51, a part of the switch component 7 is inserted into the through hole 513, and a part of the switch component 7 inserted into the through hole 513 is engaged with the through hole 513.

It will be understood by those skilled in the art that the foregoing embodiments are specific examples of the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in its practical application.
