Abstract

Disclosed is an electric hair dryer with dual-purpose length, comprising a housing body (1), an insulating sheath (2) being detachably mounted on the outer wall of a front housing (11) of the housing body (1). When the insulating sheath (2) is not being used, the short body design of the electric hair dryer makes operation more flexible and convenient, reducing the labour intensity for a user. To meet the requirements of users for tasks in which the front housing (11) is customarily gripped, when the insulating sheath (2) is being used, the insulating sheath (2) is located on the outside of the front housing (11) so as not to be directly heated by hot air in the housing body (1) and electrical heating elements. Therefore, even after a long period of use, the insulating sheath (2) will still not cause burns and the user can grip the insulating sheath (2) as needed for drying or shaping tasks without being burned.

Description

Long and short dual-purpose hair dryer

The utility model relates to an electric hair dryer, in particular to a long and short dual-purpose electric hair dryer. Background technique

The electric hair dryer generally comprises a casing composed of a front casing and a rear casing, a handle, and a motor, a fan blade, an electric heating component and the like disposed in the casing. During operation, the motor drives the blade to rotate and sucks air from the air inlet and toward the air inlet. Before the conveyance, the air is directly or after being heated by the electric heating element and blown out from the air outlet for use, but the existing hair dryer has disadvantages, for example, in order to reduce the labor intensity of the user under current market requirements, Improve the flexibility of operation, the hair dryer shell will be shortened as much as possible, so that the operation of the short hair dryer is more flexible, but for some users who are used to holding the front shell operation, the short hair dryer is used for this purpose. The habitual person has two drawbacks. One is that the front case is short, which is inconvenient for the user to hold the hand. The second is that the case is thin and will become very hot after a long time of use, which is easy to hold on the housing. Hand burns.

Summary of the invention

The purpose of the utility model is to provide a hair dryer capable of length and shortness, which is not hot after being used for a long time, and prevents the user from holding the hand on the casing from being burnt.

The utility model relates to a long-short dual-purpose electric hair dryer, which comprises a casing, and an outer wall of the front shell of the casing is detachably mounted with an insulating sleeve.

The long and short dual-purpose electric hair dryer of the utility model has an insulating sleeve detachably mounted on the outer wall of the front shell. When working, the heat insulating sleeve is located outside the front shell and is not directly heated by the hot air and the electric heating element in the housing. Therefore, even after a long time of use, the heat insulating sleeve will not be hot, and the user can hold the sleeve on the sleeve for drying or styling operation without being burnt. DRAWINGS

As shown in FIG. 1 to FIG. 6 , a long and short dual-purpose electric hair dryer according to the present invention comprises a casing 1 , and the casing 1 is composed of a front casing 11 and a rear casing 12 , and the outer wall of the front casing 11 is detachable. The heat insulating sleeve 2 is installed, and the length of the heat insulating sleeve 2 can be designed according to requirements, and should be longer than the front shell 11 to increase the holding length of the hair dryer, and meet the requirements for holding and heat insulating the front shell. In operation, the heat insulating sleeve 2 is located outside the front casing 11 and is not directly heated by the hot air and the electric heating element in the casing 1, so that the heat insulating sleeve 2 is not hot even after a long time of use, the user The drying or styling operation can be carried out on the heat insulating sleeve 2 as needed without being burnt.

The heat insulating sleeve 2 can be detachably mounted on the front case 11 in various ways. As shown in FIG. 1 to FIG. 4, the outer wall of the front case 1 has a card position 3 distributed around its center line. The number of the card slots 3 may be one or more, as shown in FIG. 4, and the inner wall of the heat insulating sleeve 2 has an L-shaped buckle that can be engaged with the card slot 3. 4. When the card position 3 is engaged with the L-shaped buckle 4, the two inner walls of the L-shaped buckle 4 respectively abut against the rear wall and the left wall (or the right wall) of the card position, so as to be restrained when being engaged The axial movement between the heat sleeve 2 and the front case 11 occurs. When installing, the heat insulating sleeve 2 is inserted into the front case 11 and rotated to the L-shaped buckle 4 to engage with the card position 3 of the front case 11. As shown in FIG. 4, in order to make the card slot 3 and the buckle 4 better engaged, the middle portion of the card slot 3 is provided with a recess 31, and the inner wall of the heat insulating sleeve 2 is provided with a position corresponding to the recess 31. The projection 41 of the recess 31 is inserted into the recess 31, and the surface of the projection 41 facing the recess 31 is a curved surface having a low middle side, so that the bump 41 can smoothly enter the recess 31 when the insulating sleeve is rotated. The number of the grooves 31 may be one or plural, as shown in FIG. 4, and the number of the bumps 41 may be one or more, as shown in FIG. Of course, in addition to the above-mentioned snap-in manner, the heat-insulating sleeve 2 can also be detachably mounted on the front case 11 by a screw-fit connection; or directly attached to the front case 11 by an interference fit connection, but Threaded joints and interference fits are common connections and will not be repeated here. As shown in FIG. 3, a gap 5 is formed between the middle portion of the heat insulating sleeve 2 and the middle portion of the front shell 11, and the contact area between the heat insulating sleeve 2 and the front shell 11 can be greatly reduced by the gap 5, thereby The heat transfer between the front case 11 and the heat insulating sleeve 2 is reduced to further prevent the heat insulating sleeve 2 from being burnt. As shown in FIG. 3, the front portion of the inner wall of the heat insulating sleeve 2 is provided with a step 21, and when the heat insulating sleeve 2 is mounted on the front case 11, the side wall of the step 21 abuts against the front end wall of the front case 11.

As shown in FIG. 5, in order to further prevent the heat insulating sleeve 2 from being hot, a sealing ring 6 may be disposed on the outer wall of the front case 11 or the inner wall of the heat insulating sleeve 2 corresponding to the air outlet. The sealing ring 6 may be a silicone rubber. Ring, in use, the sealing ring 6 abuts against the heat insulating sleeve 2 and the front shell 11, preventing hot air from entering the gap 5 in the middle from the gap between the front end of the heat insulating sleeve 2 and the front shell 11 to cause the heat insulating sleeve 2 The temperature rises.

As shown in FIG. 5 and FIG. 6, in order to meet the use requirements, a flap 22 may be disposed at the front portion of the inner wall of the heat insulating sleeve 2, and the inner wall of the heat insulating sleeve 2 may be insulated from the position in front of the flap 22. The center line of the sleeve 2 is provided with a stopper 23 for mounting the prior art tuyère 7. The outer wall of the tuyère 7 is provided with a second step 71 into which the heat insulating sleeve 2 can be inserted, and the front end of the second step 71 has a flange 72, the flange 72 is provided with a notch 73 through which the stopper 23 passes. When the tuyeres 7 are installed, the notch 73 of the tuyeres 7 is adjusted to face the corresponding stoppers, and then the tuyeres 7 are inserted into the heat insulating sleeve 2 And rotating to the flange 72 to be engaged between the stopper 23 and the blocking piece 22, at this time, the front end wall of the air nozzle 7 abuts against the blocking piece 22 of the heat insulating sleeve 2, and the front end of the heat insulating sleeve 2 The wall abuts against the front end wall of the second step 71.
