[0038] Figure 1 is a schematic diagram of the structure of a hair dryer provided by an embodiment of the utility model, Figure 2 yes Figure 1 The enlarged schematic diagram of the structure at A in the middle is shown below. Figure 1 and Figure 2 The hair dryer according to the embodiment of the utility model is described.

[0039] like Figure 1 As shown, the hair dryer 1 according to the embodiment of the utility model comprises: a housing 11 , a first bracket 12 and a motor 15 .

[0040] The front end surface of the housing 11 is formed with an air outlet 112, and the rear end surface is formed with an air inlet 111, and the air inlet 111 and the air outlet 112 are arranged opposite to each other. The housing 11 can be made of plastic. The first bracket 12 is arranged inside the housing 11, and the first bracket 12 is provided with a receiving space 123, and the receiving space 123 is located between the air inlet 111 and the air outlet 112. The motor 15 is arranged inside the receiving space 123.

[0041] It should be noted that the first bracket 12 is used to fix the motor 15 inside the housing 11. When the motor 15 is working, it can drive the blades connected thereto to rotate, so as to inhale the external airflow through the air inlet 111 and flow out from the air outlet 112. Therefore, when the motor 15 is working, the motor 15 and the first bracket 12, as well as the first bracket 12 and the housing 11, are prone to resonate, thereby generating noise.

[0042] To this end, the motor 15 is disposed inside the accommodating space 123 through the first vibration damping member 16, and the motor 15 can form a floating state, thereby reducing the vibration between the motor 15 and the first bracket 12 and the vibration between the first bracket 12 and the shell 11 to a certain extent.

[0043] That is to say, the first vibration damping member 16 can play the role of vibration damping and connection, and the first vibration damping member 16 can be made of silicone, foamed silicone or rubber material.

[0044] In the embodiment of the utility model, the motor 15 is fixed inside the shell 11 by the first bracket 12, and the motor 15 is arranged inside the accommodating space 123 by the first vibration damping member 16. The motor 15 can form a floating state, thereby reducing the vibration between the motor 15 and the first bracket 12 and the vibration between the first bracket 12 and the shell 11 to a certain extent, thereby reducing the noise generated during the operation of the motor 15. Compared with setting a silencer structure at the motor 15, the manufacturing cost is lower, the manufacturing process is simple, and the cost performance is higher.

[0045] like Figure 1 As shown, the first bracket 12 includes a connecting portion 121 and a mounting portion 122 connected to each other, the mounting portion 122 is provided with an accommodating space 123 , and the connecting portion 121 is disposed on the inner wall of the housing 11 through the second vibration damping member 14 .

[0046] The second vibration damping member 14 can play the role of vibration damping and connection, and the second vibration damping member 14 can be made of silica gel, foamed silica gel or rubber material.

[0047] To this end, the motor 15 is arranged inside the accommodating space 123 through the first vibration damper 16, and the motor 15 can form a floating state. The first bracket 12 is arranged inside the shell 11 through the second vibration damper 14, and the first bracket 12 can form a floating state. That is to say, the vibration between the motor 15 and the first bracket 12 and the vibration between the first bracket 12 and the shell 11 can be reduced to a certain extent.

[0048] In an optional embodiment, if Figure 1 As shown, the connection portion 121 is matched with the inner wall of the housing 11 , and the second vibration damping member 14 is covered on a side of the connection portion 121 facing the inner wall of the housing 11 .

[0049] It should be noted that the connecting portion 121 can be a hollow cylindrical shape, the mounting portion 122 can also be a hollow cylindrical shape, and the accommodating space 123 includes a first space adapted to the motor body and a second space adapted to the output shaft of the motor 15. At this time, the motor body is arranged inside the first space through the first vibration damping member 16.

[0050] In addition, the first bracket 12 also includes an overlapping portion, and the connecting portion 121 is connected to the mounting portion 122 via the overlapping portion. In addition, an air flow channel is formed between two adjacent overlapping portions so that the air flow entering from the air inlet 111 passes through the air flow channel and then flows out from the air outlet 112.

[0051] Of course, the connecting portion 121, the overlapping portion and the mounting portion 122 can be integrally formed. For example, the first bracket 12 is made by injection molding to improve the structural strength.

[0052] In an optional embodiment, if Figure 1 and Figure 2 As shown, the second vibration damper 14 includes a vibration damper body 141 and a protrusion group provided on one side of the vibration damper body 141 facing the inner wall of the housing 11. The vibration damper body 141 and the protrusion group are integrally formed, and the extension direction of the protrusion group is the same as the length direction of the vibration damper body 141, and the length direction of the vibration damper body 141 is consistent with the flow direction of the airflow.

[0053] In practical applications, the protrusion group includes a plurality of protrusions 142, and the plurality of protrusions 142 are arranged at intervals along the length direction of the vibration damping member body 141. For example, three protrusions 142 are arranged at equal intervals along the length direction of the vibration damping member body 141.

[0054] In an embodiment of the utility model, the first bracket 12 is arranged inside the shell 11 through the second shock absorber 14. At this time, the protrusion 142 abuts against the inner wall of the shell 11, and the shock absorber body 141 abuts against the side of the connecting portion 121 facing the inner wall of the shell 11. The first bracket 12 can form a floating state inside the shell 11, which can reduce the vibration between the first bracket 12 and the shell 11 to a certain extent.

[0055] It is particularly important to point out that, when the connecting portion 121 is adapted to the inner wall of the shell 11 and the second vibration damper 14 is covered on the side of the connecting portion 121 facing the inner wall of the shell 11, the connecting portion 121 can be a hollow cylindrical shape. At this time, a plurality of protrusion groups are spaced apart along the circumferential direction of the connecting portion 121.

[0056] For example, eight protrusion groups are arranged at equal intervals along the circumferential direction of the connecting portion 121 .

[0057] In an optional embodiment, if Figure 1 and Figure 2 As shown, each protrusion 142 forms a point contact with the inner wall of the shell 11, and the protrusion group forms a line contact with the inner wall of the shell 11.

[0058] It should be noted that at least part of the protrusion 142 is in an arc shape, so that the protrusion 142 can form a point contact with the inner wall of the housing 11. For example, the protrusion 142 is semicircular, and the radius of the protrusion 142 can be 2 mm. When the protrusion 142 and the inner wall of the housing 11 can form a point contact, the protrusion group can form a line contact with the inner wall of the housing 11.

[0059] In the embodiment of the utility model, the protrusion 142 and the inner wall of the shell 11 can form a primary vibration reduction, and the vibration reduction member body 141 and the inner wall of the shell 11 can form a secondary vibration reduction, thereby improving the overall vibration reduction effect. In addition, the vibration reduction member body 141 and the protrusion 142 can be made of different materials, so that the vibration reduction member body 141 and the protrusion 142 have different elastic properties. For example, the protrusion 142 is easier to compress, while the vibration reduction member body 141 is more difficult to compress than the protrusion 142.

[0060] In practical applications, each protrusion 142 is in a deformed state.

[0061] Among them, the protrusion 142 has an original state and a deformed state. In the original state, the protrusion 142 is not compressed, and in the deformed state, that is, under the action of external force, the protrusion 142 has a certain amount of compression. For example, the protrusion 142 is compressed by about 20% to 40% in the deformed state.

[0062] In the embodiment of the utility model, when the second vibration damper 14 is located between the connecting portion 121 and the inner wall of the shell 11, each protrusion 142 is in a deformed state, that is, each protrusion 142 is in an extruded state, and when the size of the space between the connecting portion 121 and the inner wall of the shell 11 changes, the second vibration damper 14 still has a certain vibration damping function.

[0063] In an optional embodiment, if Figure 1 As shown, the first vibration damping member 16 is wrapped around the outer circumference of the motor 15 .

[0064] It should be noted that the structure of the first vibration damping member 16 may be the same as that of the second vibration damping member 14 , which will not be described in detail herein.

[0065] In the embodiment of the utility model, the first vibration damping member 16 is wrapped around the outer periphery of the motor 15 , so that the motor 15 can form a floating state, which can reduce the vibration between the motor 15 and the first bracket 12 to a certain extent.

[0066] In an optional embodiment, if Figure 1 and Figure 2 As shown, the hair dryer 1 further includes a second bracket 13 and a heating module (not shown in the figure).

[0067] The second bracket 13 is arranged inside the shell 11, the first bracket 12 is arranged close to the air inlet 111, and the second bracket 13 is arranged close to the air outlet 112. The second bracket 13 is adapted to the inner wall of the shell 11, and the second bracket 13 forms a ventilation channel 131. At least part of the accommodating space 123 extends into the ventilation channel 131. The first bracket 12 and the second bracket 13 are connected, and the heating module is arranged on the second bracket 13.

[0068] According to the embodiment of the utility model, the second bracket 13 is respectively connected to the heating module and the first bracket 12. The heating module is suitable for heating the airflow, and the second bracket 13 is surrounded by the outer periphery of the accommodating space 123 to heat the airflow in the ventilation channel 131, so that the airflow is heated more evenly.

[0069] It is particularly important to point out that the second bracket 13 is a heat-insulating bracket. Using the heat-insulating bracket can reduce the heat received by the first bracket 12 and prevent the motor 15 from being damaged due to excessive temperature.

[0070] In practical applications, the first bracket 12 and the second bracket 13 can be connected by snap-fit, for example, the first bracket 12 is provided with a hook, the second bracket 13 is provided with a slot, and the first bracket 12 and the second bracket 13 are connected by the hook and the slot. The second bracket 13 can be connected to the overlapped portion of the first bracket 12.

[0071] In an optional embodiment, the hair dryer 1 further includes an elastic connecting member (not shown in the figure), and the first bracket 12 is connected to the second bracket 13 via the elastic connecting member.

[0072] The elastic connecting member may be a spring, a leaf spring or a rubber plate.

[0073] In the embodiment of the utility model, the motor 15 is arranged inside the accommodating space 123 through the first vibration damping member 16, and the motor 15 can form a floating state. The first bracket 12 is arranged inside the shell 11 through the second vibration damping member 14, and the first bracket 12 can form a floating state. The first bracket 12 is connected to the second bracket 13 through an elastic connecting member. That is to say, the vibration between the motor 15 and the first bracket 12, the vibration between the first bracket 12 and the shell 11, the vibration between the first bracket 12 and the second bracket 13, and the vibration between the second bracket 13 and the shell 11 can be reduced to a certain extent, thereby reducing the noise generated during the operation of the motor 15 to a certain extent.

[0074] In practical applications, the second bracket 13 is disposed on the inner wall of the housing 11 through a third vibration damping member (not shown in the figure).

[0075] The structures of the third vibration damping member and the second vibration damping member 14 may be the same, which will not be described in detail here.

[0076] That is to say, the third vibration damping member can also play the role of vibration damping and connection support.

[0077] In an optional embodiment, the hair dryer 1 also includes a fan blade (not shown in the figure), which is located inside the shell 11, the fan blade is connected to the output shaft of the motor 15, the air inlet 111 is located on the windward side of the fan blade, and the motor 15 is located on the leeward side of the fan blade.

[0078] According to an embodiment of the utility model, the motor 15 of the hair dryer is located in the housing 11 and on the leeward side of the fan blade, so as to shorten the distance between the fan blade and the air inlet 111 and ensure the ventilation volume inside the housing 11. Moreover, compared with arranging the motor 15 in the handle, arranging the motor 15 in the housing 11 can help reduce the size of the handle so that the handle is easy to hold. In addition, since the motor 15 is located on the leeward side of the fan blade, the airflow passes through the motor 15 and cools the motor 15 before being heated by the heating module (such as a heating wire), which can facilitate the maintenance of the motor 15 and extend the life of the motor 15.

[0079] It should be noted that the hair dryer 1 also includes a handle, on which a switch is provided for controlling the working mode of the hair dryer, including hot air, cold air, hair care and other modes, as well as high-end, medium-end or low-end modes. Users can select different working modes based on their needs.

[0080] According to the embodiment of the utility model, the handle is connected to the housing 11 by means of buckles or screws, and an electric control module is arranged in the handle, and the electric control module is electrically connected to the motor 15 and the heating module.

[0081] In an optional embodiment, the hair dryer 1 further includes an air inlet grille, which is disposed at the air inlet 111 and connected to the housing 11 via buckles or screws.

[0082] According to an embodiment of the utility model, the hair dryer further comprises an air outlet grille, which is arranged at the air outlet 112 and connected to the housing 11 via buckles or screws.

[0083] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
