[0041] This utility model provides a housing structure 100, which is applicable to hair care devices such as hair dryers, hair dryers, and hair styling machines. For ease of explanation, the following description uses the application of the housing structure 100 to a hair dryer as an example; other devices can be adapted accordingly.

[0042] Specifically, please refer to Figure 1 and Figure 2 In this embodiment, the housing structure 100 includes a blower 1 and a handle 2. The blower 1 is provided with an air outlet. The handle 2 includes a first handle portion 21, a second handle portion 22 which is radially separate from the first handle portion 21, and an outer shell structure 23 sleeved on the outside of the first handle portion 21 and the second handle portion 22. The first handle portion 21 and the blower 1 are integrally formed. The outer shell structure 23 is provided with an air inlet. The first handle portion 21 and the second handle portion 22 together form an airflow guiding channel. The airflow enters the handle 2 from the air inlet and flows into the blower 1 along the airflow guiding channel and flows out from the air outlet.

[0043] In this embodiment, an air outlet is provided on the air duct 1, and an air inlet is provided on the handle 2. An airflow guiding channel is formed inside the handle 2. Airflow can enter the handle 2 from the air inlet, enter the air duct 1 under the guidance of the airflow guiding channel, and then be blown out through the air outlet of the air duct 1. The handle 2 includes a first handle 21 and a second handle 22, and a shell structure 23. The first handle 21 and the second handle 22 are arranged separately in the radial direction. The handle 2 is generally cylindrical. The first handle 21 and the second handle 22 are both generally semi-circular. The first handle 21 and the second handle 22 are combined to form the airflow guiding channel. The shell structure 23 is sleeved on the first handle 21 and the second handle 22. The outer side of the two handle portions 22 improves the strength of the handle 2, making it less prone to breakage. Furthermore, from the outer surface of the shell structure 100, the surface of the entire handle 2 is smoother and more fluid, providing a better grip experience for the user. Moreover, separating the first handle portion 21 and the second handle portion 22 makes the assembly of the internal components of the handle 2 more convenient. Components can be fixed in one of the handle portions before being closed. The assembly operation of the internal structure of the handle 2 is not limited by the space of the handle 2, making the operation more convenient and thus the assembly efficiency higher. In addition, the first handle portion 21 is integrated with the air duct 1, which reduces the number of assembly parts and makes the handle 2 less prone to rotation relative to the air duct 1, resulting in better stability.

[0044] It should be noted that both the air duct 1 and the handle 2 are approximately cylindrical in shape, and the aforementioned radial direction refers to the radial direction of the cylindrical handle 2. The axial direction of the air duct 1 and the axial direction of the handle 2 are approximately perpendicular. The air outlet is located at the front end of the air duct 1 along its axial direction, i.e., the end facing the user. The handle 2 is located on one side of the circumference of the air duct 1 and is connected to the air duct 1, allowing airflow to enter the handle 2 from the air inlet and then enter the air duct 1. The end of the handle 2 connected to the air duct 1 is the upper end, and the end of the handle 2 away from the air duct 1 is the lower end. All descriptions of orientation in this utility model can be referenced accordingly.

[0045] Among them, combined Figure 2 and Figure 3As shown, the first handle 21 includes a first handle body 211 and a first connecting portion 212 disposed at one end of the first handle body 211. The first handle body 211 and the first connecting portion 212 are arranged sequentially along the axial direction of the handle 2. The first connecting portion 212 is arranged in a ring shape and connected to the air duct 1, so that the handle 2 and the air duct 1 form a complete ring shape at the joint, thereby facilitating the connection and assembly of the first handle 21 and the second handle 22 and ensuring the structural strength of the joint between the handle 2 and the air duct 1. The second handle 22 is connected to the first handle body 211 and positioned with the first connecting portion 212. The second handle 22 and the first connecting portion 212 form a limiting fit along the radial direction of the handle 2. The second handle 22 and the first handle body 211 form a relative fixation along the axial direction of the handle 2, thereby completely restricting the second handle 22 onto the first handle 21, making the first handle 21 and the second handle 22 easy to install.

[0046] Furthermore, the first connecting portion 212 is annular, and one side of the first connecting portion 212 is connected to the first handle body 211. Specifically, half of the first connecting portion 212 is connected to the first handle body 211. Preferably, the first connecting portion 212 and the first handle body 211 are integrally formed. A positioning protrusion 2121 protrudes from the other side of the first connecting portion 212, that is, the end of the other half of the first connecting portion 212 is provided with a positioning protrusion 2121. The positioning protrusion 2121 protrudes along the axial direction of the first connecting portion 212 at the end facing away from the air duct 1. The second handle 22 is provided with a positioning groove. The positioning protrusion 2121 engages with the positioning groove, thereby positioning one end of the second handle 22 along its axial direction through the positioning protrusion 2121 and the positioning groove, and initially fixing the second handle 22 to the first handle 21.

[0047] Moreover, combined Figure 3 and Figure 4 As shown, a snap-fit ​​portion is provided on the first handle body 211, and a fastening portion is provided on the second handle 22 to engage with the snap-fit ​​portion. The snap-fit ​​portion and the fastening portion form a fastening engagement along the radial direction of the handle 2. The snap-fit ​​portion includes multiple hooks 2113 provided on the side of the first handle body 211, and the fastening portion includes multiple slots 2212 provided on the side of the second handle 22. The multiple hooks 2113 and the multiple slots 2212 are engaged in a one-to-one snap-fit ​​engagement, so that the second handle 22 can be fastened and fixed to the first handle 21, thereby facilitating further locking and fixing operations between the first handle 21 and the second handle 22.

[0048] Furthermore, such as Figure 3 As shown, the first handle body 211 is provided with a plurality of first mounting holes 2111, which are spaced apart along the axial direction of the handle 2 to be evenly distributed in the middle and lower part of the first handle body 211; the second handle body 221 is provided with a plurality of second mounting holes 2211, which are arranged in a one-to-one correspondence with the plurality of first mounting holes 2111; the housing structure 100 also includes a plurality of first connecting members, which are respectively inserted into the plurality of first mounting holes 2111 and the plurality of second mounting holes 2211 to connect and fix the first handle body 211 and the second handle body 221. The first connecting members can be configured as screws, bolts, or pins, etc. The first handle portion 21 and the second handle portion 22 can be connected and fixed through the first connecting members, ensuring a more stable and reliable fixation between the first handle portion 21 and the second handle portion 22.

[0049] Furthermore, the first handle portion 21 also includes a second connecting portion 213 located at the other end of the first handle body 211, specifically at the bottom of the first handle body 211. The second handle portion 22 includes a second handle body 221 and a third connecting portion 222 located at the end of the second handle body 221 facing away from the air duct 1. The second handle body 221 is connected to the first handle body 211, and the second connecting portion 213 is connected to the third connecting portion 222. The first handle body 211 and the second handle body 221 are used to enclose the main electrical components inside the handle 2, such as the suction fan, to prevent external debris from entering the suction fan. Multiple hollow areas are provided on the second connecting portion 213 and the third connecting portion 222 to allow external airflow to enter the suction fan. By segmenting the handle 2, the air intake volume is increased while better protecting the internal components.

[0050] Preferably, such as Figure 2As shown, the outer shell structure 23 includes a protective shell 231, a filter cartridge 232, and an air inlet hood 233. The protective shell 231 is fitted onto the outside of the first handle body 211, the first connecting part 212, and the second handle body 221 to cover the joint between the first handle body 211 and the second handle body 221, making the outer surface of the handle 2 more complete and smoother, and providing a better grip for the user. One end of the protective shell 231 abuts against the air duct 1, and the second connecting part 213 and the third connecting part 222 protrude from the protective shell 231. The filter cartridge 232 is fitted onto the outside of the second connecting part 213 and the third connecting part 222. The air inlet hood 233 is fitted onto the outside of the filter cartridge 232 and abuts against the other end of the protective shell 231, and the air inlet is located on the air inlet hood 233. The filter cartridge 232 and the air inlet cover 233 are supported and fixed by the second connecting part 213 and the third connecting part 222, and the air inlet can be better misaligned with the first handle body 211 and the second handle body 221, which can better protect the internal components. At the same time, more air inlets can be set to better ensure the air intake.

[0051] The filter cartridge 232 is used to filter impurities in the airflow entering from the air inlet, preventing debris from entering the suction fan and affecting its normal operation, and also better protecting the entire blower. However, after the blower has been in operation for a long time, a lot of debris will accumulate on the filter cartridge 232, causing the filter holes to become clogged, thus affecting the air intake efficiency.

[0052] Furthermore, the air inlet hood 233 is detachably disposed on the outside of the filter cartridge 232, making it easy to disassemble and assemble the air inlet hood 233, thereby facilitating the cleaning of the filter cartridge 232 and ensuring better air intake performance.

[0053] The filter cartridge 232, the second connecting part 213, and the third connecting part 222 are magnetically attracted to each other. Specifically, as shown... Figure 5As shown, a first through hole is provided at the end of the protective shell 231 facing away from the air duct 1 (i.e., the bottom end of the protective shell 231), and a second through hole is provided at the end of the filter cylinder 232 facing away from the protective shell 231 (i.e., the bottom end of the filter cylinder 232). The first through hole and the second through hole are arranged opposite to each other. At least one of the second connecting part 213 and the third connecting part 222 is provided with a first magnetic attraction part. The first magnetic attraction part can be exposed from the first through hole and the second through hole. A second magnetic attraction part 2331 is provided on the inner side of the air inlet cover 233, which magnetically engages with the first magnetic attraction part. The first magnetic attraction part and the second magnetic attraction part 2331 are magnetically attracted to fix the air inlet cover 233 to the outside of the filter cylinder 232. The air inlet cover 233 is more easily disassembled and assembled by magnetic attraction, thereby facilitating the cleaning of the filter cylinder 232. Preferably, there are two first magnetic suction parts, which are respectively located at the bottom of the second connecting part 213 and the bottom of the third connecting part 222, and both can be exposed or protruding from the first through hole and the second through hole, so as to better magnetically attract with the second magnetic suction part 2331. The number of second magnetic suction parts 2331 can be the same as the number of first magnetic suction parts, and two are also provided to ensure a better fixing effect, ensuring that the air inlet cover 233 is not easy to fall off during use, and is also easy to remove during disassembly.

[0054] Preferably, the outer surface of the protective shell 231 is flush with the outer surface of the air inlet cover 233, making the entire handle 2 smoother and providing a better grip.

[0055] Moreover, combined Figures 2 to 4 As shown, the second connecting part 213 and the third connecting part 222 are provided with a third mounting hole 223 at the end facing away from the air duct 1, and the filter cylinder 232 is provided with a fourth mounting hole 2321 corresponding to the third mounting hole 223 at the end facing away from the air duct 1. Similarly, the second connecting part 213 and the filter cylinder 232, as well as the third connecting part 222 and the filter cylinder 232, can be connected and fixed by screws, bolts or pins passing through the third mounting hole 223 and the fourth mounting hole 2321, to ensure that the filter cylinder 232 is more reliably fixed and will not shake.

[0056] Similarly, a fifth mounting hole 2112 is provided at the end of the first handle body 211 and the second handle body 221 facing away from the air duct 1, and a sixth mounting hole 2311 is provided at the end of the protective shell 231 facing away from the air duct 1. The sixth mounting hole 2311 corresponds to the fifth mounting hole. Screws, bolts, or pins are inserted into the fifth mounting hole 2112 and the sixth mounting hole 2311 to connect and fix the first handle body 211 and the protective shell 231, as well as the second handle body 221 and the protective shell 231, making the protective shell 231 less prone to collapsing.

[0057] This utility model also provides a hair care device, which includes the aforementioned housing structure 100. Through the housing structure 100, the hair care device is easier to assemble and more convenient to assemble, thus effectively improving the assembly efficiency of the hair care device.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
