Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0031] As Figures 1-5 shown, the present utility model provides a hair dryer assembly structure, including an outer shell 1, a movement assembly 2 and a tail cap 3. One end of the outer shell 1 is provided with an air outlet 11, and the other end is provided with an air inlet 12. The movement assembly 2 is inserted into the outer shell 1 from the air outlet 11 and is fixedly connected to the outer shell 1. The tail cap 3 is inserted into the outer shell 1 from the air inlet 12 and is fixedly connected to the outer shell 1;

[0032] Wherein, at least one positioning rib 13 is provided on the inner wall of the outer shell 1. One end of the positioning rib 13 close to the air outlet 11 is in limiting abutment with the movement component 2, and one end close to the air inlet 12 is in limiting abutment with the end cover 3.

[0033] During installation, the movement component 2 and the end cover 3 are respectively inserted into the outer shell 1 from the air outlet 11 and the air inlet 12 of the outer shell 1. When both the movement component 2 and the end cover 3 are in abutment and fixed with the positioning rib 13, the connection and installation of the movement component 2, the end cover 3 and the outer shell 1 are completed. During disassembly, only the movement component 2 and the end cover 3 need to be taken out from the air outlet 11 and the air inlet 12 of the outer shell 1 respectively.

[0034] In the installation structure of the existing hair dryer, usually the internal components (not shown) inside the outer shell 1 are integrated into an integrated device (not shown) and then installed into the outer shell 1 together. When individual components need to be repaired or replaced, the integrated device needs to be taken out together, and then the individual components are disassembled, repaired or replaced. This is not only time-consuming and laborious, but also there is a risk of damaging the components and the internal structure of the outer shell 1, resulting in inability to install or use. However, the present utility model effectively solves or alleviates the problem of difficult repair and rework such as repairing or replacing components of the existing hair dryer through the setting of the positioning rib 13. At the same time, the assembly structure is simple, which is beneficial to large-scale mechanized batch processing, thereby improving production efficiency.

[0035] Specifically, the movement component 2 includes an inner shell 21 and a motor bracket 22. One end of the inner shell 21 is fixedly connected to one end of the motor bracket 22 to form an integrated structure. A heating bracket 211 is provided inside the inner shell 21, and a blower 221 is provided inside the motor bracket 22. During installation, the movement component 2 is installed inside the outer shell 1, and the motor bracket 22 is installed at one end close to the air inlet 12, while the end of the inner shell 21 away from the motor bracket 22 faces the air outlet 11.

[0036] Wherein, a plurality of bosses 222 corresponding to the positioning rib 13 are provided on the outer peripheral wall of one end of the motor bracket 22 close to the inner shell 21. During installation, the end face of the boss 222 facing the air inlet 12 abuts and fixes with one end of the positioning rib 13 close to the air outlet 11, so as to realize the axial (the axial direction is the direction parallel to the length direction of the outer shell 1) movement limit of the movement component 2.

[0037] Further, as Figure 5As shown, one end of the positioning rib 13 that abuts against the boss 222 is provided with a clamping portion 131 having an "L" - shaped structure. The clamping portion 131 includes an abutting surface 1311 and a supporting surface 1312. During installation, the end face of the boss 222 facing the air inlet 12 abuts against the abutting surface 1311, and the side wall of the boss 222 abuts against the supporting surface 1312. Through the setting of the supporting surface 1312, the radial movement (the radial direction means the direction perpendicular to the axial direction, that is, the direction perpendicular to the length direction of the outer shell 1) of the boss 222 and the movement of the movement mechanism assembly 2 are limited, thereby preventing internal shaking during the use of the hair dryer, and further effectively improving the user experience of consumers;

[0038] Furthermore, as Figure 6 shown, a guiding block 14 is further provided on the inner peripheral wall of the outer shell 1, and a guiding groove 212 corresponding to the guiding block 14 is provided on the outer peripheral wall of the inner shell 21. During the process of installing the movement mechanism assembly 2 into the outer shell 1, the guiding block 14 slides in the guiding groove 212 and has a guiding effect on the installation of the movement mechanism assembly 2 and the outer shell 1;

[0039] Preferably, in order to improve the installation convenience of the movement mechanism assembly 2 and the outer shell 1 and improve the installation efficiency, the guiding groove 212 includes a fixing portion 2121 and a guiding portion 2122. The guiding portion 2122 is connected to one end of the fixing portion 2121 close to the air inlet 12. The guiding portion 2122 has a "V" - shaped structure, so that the opening distance of the guiding portion 2122 at the end close to the air inlet 12 is greater than the opening distance at the other end. During the fixing process of the movement mechanism assembly 2 in the outer shell 1, when the guiding block 14 abuts against the inner wall of the guiding portion 2122, due to the "V" - shaped structure of the guiding portion 2122, the guiding block 14 can be guided to move along the inner wall of the guiding portion 2122 into the fixing portion 2121, so as to achieve the purpose of improving the installation efficiency;

[0040] Specifically, as Figure 5 shown, an annular limiting step 15 is provided on the inner wall of one end of the outer shell 1 close to the air outlet 11, and a limiting convex ring 213 corresponding to the limiting step 15 is provided on the outer peripheral wall of one end of the inner shell 21 away from the motor bracket 22. During installation, while the boss 222 on the motor bracket 22 abuts and is fixed to the positioning rib 13, the limiting step 15 also abuts and is fixed to the limiting convex ring 213, thereby further improving the installation firmness of the movement mechanism assembly 2 in the outer shell 1;

[0041] Further, as Figure 7As shown, in order to better fix the movement assembly 2, prevent the movement assembly 2 from falling off at the air outlet 11 and improve the aesthetics of the air outlet 11 of the hair dryer, a front fixing ring 4 is further provided at the air outlet 11. One end of the front fixing ring 4 is provided with a plurality of first clamping corners 41. One end of the limiting convex ring 213 close to the air outlet 11 is provided with a clamping groove 2131 corresponding to the first clamping corners 41. During installation, the front fixing ring 4 is clamped and fixed to the limiting convex ring 213 through the first clamping corners 41 and the clamping groove 2131;

[0042] Preferably, a gap 5 is provided between the limiting convex ring 213 and the inner wall of the housing 1. The peripheral wall edge of the front fixing ring 4 is provided with a plurality of second clamping corners 42 corresponding to the position of the gap 5. During installation, the second clamping corners 42 of the front fixing ring 4 are inserted into the gap 5, so as to realize the clamping and fixing of the limiting convex ring 213 and the housing 1 in the radial direction, and further effectively prevent the limiting convex ring 213 from shaking in the housing 1, thereby improving the user experience of consumers;

[0043] Specifically, as Figure 8 shown, one end of the tail cover 3 close to the positioning rib 13 is provided with a clamping groove 31 corresponding to the positioning rib 13. During installation, the positioning rib 13 is clamped and fixed to the clamping groove 31 of the tail cover 3, so as to achieve the effect of clamping and fixing the tail cover 3;

[0044] Furthermore, as Figure 9 shown, one end of the motor bracket 22 close to the air inlet 12 is provided with a connecting column 223. The tail cover 3 is provided with a connecting sleeve 32 corresponding to the connecting column 223. During installation, the connecting sleeve 32 is correspondingly sleeved on the connecting column 223, so as to realize the fixation of the housing 1, the tail cover 3 and the motor bracket 22;

[0045] Preferably, the connecting sleeve 32 and the connecting column 223 are connected and fixed by screws 33;

[0046] Specifically, as Figure 10 shown, a rear fixing cover 6 is sleeved on one end of the tail cover 3 away from the motor bracket 22. One end of the rear fixing cover 6 away from the tail cover 3 is provided with a plurality of through holes 61 for air intake. The inner peripheral wall of one end of the rear fixing cover 6 close to the tail cover 3 is provided with an "L"-shaped fixing groove 62. The outer peripheral wall of the tail cover 3 is provided with fixing lugs 34 corresponding to the fixing groove 62. During installation, the rear fixing cover 6 moves towards the tail cover 3, so that the fixing lugs 34 enter the fixing groove 62, and then by rotating the rear fixing cover 6, the fixing lugs 34 move along the "L"-shaped direction of the fixing groove 62, so as to realize the connection and locking of the rear fixing cover 6 and the tail cover 3;

[0047] Further, a recess 341 is provided on the fixed lug 34, and a protrusion 621 corresponding to the recess 341 is provided in the fixed groove 62. After the tail cover 3 and the rear fixed cover 6 are snapped together through the fixed lug 34 and the fixed groove 62, the protrusion 621 in the fixed groove 62 is snap-fitted with the recess 341 of the fixed lug 34, thereby improving the snap-fitting firmness between the tail cover 3 and the rear fixed cover 6;

[0048] Preferably, as Figure 3 shown, a filter net 7 is further provided between the rear fixed cover 6 and the tail cover 3. The filter net 7 is fixedly connected to the tail cover 3 by screws 33. Through the arrangement of the filter net 7 and the through hole 61, a double filtering effect is formed at the air inlet 12 of the hair dryer, thereby effectively preventing dust from entering the interior of the housing 1 and damaging the internal components therein, and further improving the service life of the hair dryer.

[0049] It should be noted that under the same effect, the arrangement positions between the guide block 14 and the guide groove 212, the connecting column 223 and the connecting sleeve 32, the fixed lug 34 and the fixed groove 62, and the recess 341 and the protrusion 621 can be exchanged with each other;

[0050] The working principle of the present invention will be described in detail below;

[0051] During installation, the movement assembly 2 is inserted into the housing 1 from the air inlet 12 of the housing 1, and through the guiding action of the guide groove 212 and the guide block 14, as well as the abutting action of the convex platform 222 and the positioning rib 13, the connection and installation of the movement assembly 2 and the housing 1 are completed; then the tail cover 3 is inserted into the housing 1 from the air inlet 12 of the housing 1. After the positioning rib 13 is snap-fitted and fixed with the card slot 31, the connecting column 223 of the movement assembly 2 and the connecting sleeve 32 of the tail cover 3 are connected and fixed by screws 33, thereby completing the installation of the tail cover 3, the housing 1, and the movement assembly 2. Finally, the front fixing ring 4, the filter net 7, and the rear fixed cover 6 are respectively installed at the air inlet 12 and the air outlet 11, thereby completing the overall installation of the housing 1 part of the hair dryer.

[0052] The innovation of the present utility model lies in that the movement assembly and the end cap are respectively inserted into the housing from different ends of the housing, and the positioning ribs provided on the inner wall of the housing are used to realize the fixed connection of the movement assembly, the end cap and the housing, effectively solving the problems in the prior art that when repairing a single component inside the housing, the entire internal structure of the housing needs to be disassembled, resulting in difficult repair rework and high damage risk; at the same time, the assembly structure is simple, facilitating large-scale mechanized production and processing, thereby improving production efficiency and reducing production costs.
