Abstract
Description
Technical Field
[0001] This utility model relates to the field of household appliance technology, specifically to a hair dryer housing and a hair dryer. Background Technology
[0002] Traditional hair dryers have their handles fixed to the blower tube via a protruding connecting cylinder on the side wall. This protrusion creates a concave side during injection molding, forcing the mold to use radial parting and preventing axial core pulling. This results in a parting line on the outer circumference of the blower tube. The parting line not only damages the appearance but also requires grinding, painting, or applying decorative parts to cover it, increasing the number of processes, reducing yield, and raising costs.

[0032] Example 1
[0033] like Figures 1-3 As shown, Figure 1 This is a three-dimensional structural diagram of the hair dryer casing; Figure 2 This is a cross-sectional view of the hair dryer casing; Figure 3 This is a schematic diagram of the disassembled structure of the hair dryer casing. The hair dryer casing includes a blower nozzle 1 and a handle 2. The blower nozzle 1 is used to support other components and works with other components to blow hot or cold air. The handle 2 is connected to the outer wall of the blower nozzle 1 for easy gripping by the user.
[0034] Please refer to the following: Figure 4As shown, Figure 4 This is a three-dimensional structural diagram of the hair dryer 1. The hair dryer 1 has a receiving groove 11, an air outlet 12, and a first mounting hole 13. The receiving groove 11 is opened along the axial direction of the hair dryer 1, and all other components are located in the receiving groove 11 during use. The air outlet 12 is located at the end of the hair dryer 1 and is connected to the receiving groove 11. Hot or cold air can be discharged through the air outlet 12. The first mounting hole 13 is opened on the outer surface of the hair dryer 1 and is connected to the receiving groove 11. The handle 2 is disposed in the first mounting hole 13.
[0035] Please refer to the following: Figures 5-9 , Figure 5 This is a three-dimensional structural diagram of the connecting cylinder 21; Figure 6 This is another three-dimensional structural diagram of the connecting cylinder 21; Figure 7 This is a front view of the connecting cylinder 21; Figure 8 This is a three-dimensional structural diagram of the inner cylinder 22; Figure 9 This is a three-dimensional structural diagram of the outer cylinder 23. The handle 2 includes a connecting cylinder 21, an inner cylinder 22, and an outer cylinder 23. The connecting cylinder 21 is disposed in the first mounting hole 13. The inner cylinder 22 is connected to the connecting cylinder 21. The outer cylinder 23 is sleeved on the outer surface of the inner cylinder 22 and the connecting cylinder 21, and is connected to the outer wall of the blower 1. Specifically, the connecting cylinder 21 and the blower 1 are connected by ultrasonic welding. The inner cylinder 22 and the connecting cylinder 21 are detachably connected, and the outer cylinder 23 and the outer wall of the blower 1 are also detachably connected. It should be noted that the detachable connection can use existing threaded connections; of course, other existing structures can also be used.
[0036] The connecting cylinder 21 includes a support plate 211 and a cylinder body 212 connected to the support plate 211. In use, the support plate 211 is located on the inner wall surface of the receiving groove 11 and is disposed around the first mounting hole 13, with the cylinder body 212 penetrating through the first mounting hole 13. Furthermore, the support plate 211 has a first slot 2111, and correspondingly, the inner wall surface of the receiving groove 11 is provided with a first retaining strip 111, which is engaged in the first slot 2111. In this embodiment, the first retaining strip 111 and the first slot 2111 are detachably connected. The cooperation between the first retaining strip 111 and the first slot 2111 can help improve the stability of the connection between the connecting cylinder 21 and the blower 1. Furthermore, the support piece 211 also has a second slot 2112. Correspondingly, the inner wall of the receiving groove 11 is provided with a second locking strip 112, wherein the second locking strip 112 is locked in the second slot 2112. In this embodiment, the second locking strip 112 and the second slot 2112 are also detachably connected. Through the cooperation of the second locking strip 112 and the second slot 2112, the connection between the connecting cylinder 21 and the blower 1 can be further stabilized.
[0037] The connecting cylinder 21 also has a second mounting hole 213 penetrating the support plate 211 and the cylinder body 212. The second mounting hole 213 communicates with the receiving groove 11, and the inner cylinder 22 is detachably disposed within the second mounting hole 213. Specifically, the cylinder body 212 has a third slot 2121, and the inner cylinder 22 is provided with a locking block 221. In use, the locking block 221 is located within the third slot 2121. Through the cooperation of the locking block 221 and the third slot 2121, the connecting cylinder 21 and the inner cylinder 22 remain connected. When the locking block 221 disengages from the third slot 2121, the connecting cylinder 21 and the inner cylinder 22 can be separated. It should be noted that, in addition to the detachable connection between the locking block 221 and the third slot 2121, a threaded connection can also be added between the connecting cylinder 21 and the inner cylinder 22 to further secure the connection.
[0038] Furthermore, the outer wall surface of the cylinder 212 has at least one positioning groove 2122, and the outer cylinder 23 is provided with at least one positioning strip 231. In use, the positioning strip 231 is engaged in the positioning groove 2122 to fix the connection between the connecting cylinder 21 and the outer cylinder 23. Specifically, the outer wall surface of the cylinder 212 has two positioning grooves 2122, which are distributed opposite to each other. Correspondingly, the outer cylinder 23 is provided with two positioning strips 231, which are also distributed opposite to each other. In use, the two positioning strips 231 are respectively engaged in the two positioning grooves 2122, further reinforcing the connection between the connecting cylinder 21 and the outer cylinder 23, while also serving as a foolproof mechanism and improving assembly efficiency.
[0039] In practical applications, one end of the outer cylinder 23 is provided with a joint edge 232, which is connected to the outer wall surface of the blower 1. By setting the joint edge 232, the connection between the outer cylinder 23 and the blower 1 can be made tighter, the connection effect is better, and the aesthetics of the two after connection can also be improved.
[0040] In this embodiment, the first mounting hole 13 is located at the lower part of the blower tube 1 and on the arc-shaped structure of the blower tube 1. Therefore, in order to improve the connection effect between the connecting tube 21 and the blower tube 1, the cross-section of the support piece 211 is also arc-shaped, so that the support piece 211 can fit against the inner wall of the receiving groove 11. Similarly, in order to improve the connection effect between the outer tube 23 and the blower tube 1, the cross-section of the joining edge 232 is also arc-shaped, so that the joining edge 232 can fit against the outer wall of the blower tube 1.
[0041] In summary, the connecting cylinder 21 and the blower 1 adopt a separate structure. During assembly, the support plate 211 of the connecting cylinder 21 connects to the periphery of the first assembly hole 13, and the cylinder body 212 passes through the first assembly hole 13. Then, the inner cylinder 22 and the outer cylinder 23 are assembled in sequence. In this way, the blower 1 and the connecting cylinder 21 can be manufactured separately, and the blower 1 can be produced by axial demolding, thus solving the problem of parting line in the traditional structure. Later, there is no need for grinding and painting, which simplifies the process, improves the yield rate, and greatly reduces the cost.
