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, which is composed of an inner wall 1, an outer wall 2, and an air guide grill 3, as shown in fig. 1 and 2. Wherein, the inner wall 1 is connected with the body part 6 of the hair dryer, and the outer wall 2 surrounds the inner wall 1 and is arranged opposite to the inner wall 1. And, the inner wall 1 and the body 6 of the hair dryer jointly form an air duct of the hair dryer, and a fan of the hair dryer is arranged in the air duct, the fan sucks outside air flow into the air duct, and the air flow is brought to an air outlet through the fan in the air duct, so that the blowing function of the hair dryer is realized. In addition, the air guide grid 3 is also arranged in the air duct and is connected with the inner wall 1, the air guide grid 3 is used for guiding partial air flow generated by the fan to the direction of the main control circuit board 4 arranged in the body 6 of the hair dryer, the air duct is divided into two areas, one of the two areas is a main air duct capable of flowing through more air flow, the other area is a heat dissipation air duct capable of flowing through less air flow, most of the air flow from the air inlet to the air outlet is conveyed through the main air duct, the air blowing function is realized, and a small part of the air flow in the air duct can be directly blown to the main control circuit board 4 through the heat dissipation air duct, so that partial air flow in the air duct can be intensively blown to the position of the main control circuit board 4, the main control circuit board 4 is cooled more effectively, and the main control.
From the above, it can be easily found that, since the outer wall 2 is disposed around the inner wall 1, and the inner wall 1 is connected to the body 6 of the hair dryer and encloses the air duct, a closed space can be formed in the outer wall 2 to prevent the air flow inside the air duct from diffusing outwards. In addition, the air guide grids 3 are arranged in the air duct, a heat dissipation air duct is formed by the air guide grids 3, and partial air flow generated by the fan is directly guided to the position where the main control circuit board 4 is installed, so that the partial air flow can be directly blown to the position where the main control circuit board 4 is installed. Therefore, when the hair dryer works, partial air flow can be blown to the position of the main control circuit board 4 all the time to cool the main control circuit board 4, so that the overhigh temperature of the main control circuit board 4 in the hair dryer can be effectively avoided, the service life of the main control circuit board is prolonged, and the service life of the whole hair dryer is further prolonged.
In addition, in the present embodiment, as shown in fig. 2, in order to better radiate heat from the main control circuit board 4, the air guide grille 3 is disposed right below the main control circuit board 4, so that part of the air flow in the air duct can be directly blown to the main control circuit board 4, thereby improving the heat radiation efficiency of the main control circuit board 4. The main control circuit board 4 may be a hard circuit board or a flexible circuit board, and the material of the main control circuit board and the components arranged on the main control circuit board may be adjusted according to actual use conditions.
Preferably, in the present embodiment, as shown in fig. 2, the air guide grille 3 is formed by recessing the portion of the inner wall 1 toward the inside of the air duct to form a recessed portion, and then forming the recessed portion by forming a through hole in the flow direction of the air flow in the air duct, so that the air guide grille 3 can be easily molded while guiding the air flow, thereby reducing the manufacturing cost. Of course, in the practical application process, in order to conveniently maintain and replace the air guide grille 3 or the inner wall 1, the air guide grille 3 can be set as an independent component, and the air guide grille 3 and the inner wall 1 can be detachably connected, for example, after the air guide grille 3 is formed, the air guide grille 3 and the inner wall 1 are locked and fixed through bolts, so that the air guide grille 3 and the inner wall 1 are connected into a whole, and when the air guide grille 3 or the inner wall 1 needs to be maintained and replaced, the bolts are unscrewed, the air guide grille 3 can be separated from the inner wall 1, and therefore, the air guide grille 3 or the inner wall 1 can be conveniently maintained and replaced.
In the present embodiment, as shown in fig. 2, the inner wall 1 is spaced apart from the outer wall 2, and the area of the inner wall 1 spaced apart from the outer wall 2 forms a housing area 7 for mounting the switch assembly 5, and the housing area and the air guide grill 3 are disposed opposite to each other along the axial direction of the hair dryer body 6. Therefore, the switch assembly 5 can be arranged in the area outside the air duct in the arrangement mode, the outward diffusion of air flow through the joint of the connection part of the switch assembly 5 and the outer wall 2 is avoided, the loss of air volume is reduced, and the sealing performance of the air duct is further improved. In addition, in order to reduce the manufacturing cost, the accommodating area 7 is formed by recessing a part of the inner wall 1 towards the inner side of the air duct to form a groove, so that the inner wall 1 and the outer wall 2 are formed in a spaced manner, and the area formed between the groove and the outer wall 2 is the accommodating area 7.
A second embodiment of the present invention relates to a hair dryer, comprising: the fan, the body, set up master control circuit board in the body, the handle as described in the first embodiment. Wherein, the inner wall of handle links to each other with the somatic part, and the fan setting is in the wind channel of closing by the inner wall of handle and closing. Therefore, the main control circuit board can be directly cooled through the independent air channel formed at the air guide grid, the overhigh temperature at the main control circuit board is avoided, and the service life of the hair dryer is effectively prolonged.
it should be noted that this embodiment is a system embodiment corresponding to the first embodiment, and this embodiment can be implemented in cooperation with the first embodiment. The related technical details mentioned in the first embodiment are still valid in this embodiment, and are not described herein again in order to reduce repetition. Accordingly, the related-art details mentioned in the present embodiment can also be applied to the first embodiment.
