Description

Technical Field

[0001] This utility model relates to the field of hair dryer motor technology, and in particular to a novel motor that is easy to disassemble. Background Technology

[0002] The duct motor is the core component that enables the blowing function in a hair dryer. The duct motor includes a duct housing, with the stator core mounted inside the housing, and the motor housing fitted over the outer side of the duct housing. In existing duct motor designs, combined with... Figure 6 As shown, the motor housing 20 is directly fitted onto the outside of the duct housing 10. Limiting protrusions 21 are provided at both the front and rear ends of the inner wall of the motor housing 20. These limiting protrusions 21 are used to limit the duct housing 10, preventing it from falling out from the front or rear end of the motor housing. While this structural design is simple and reliable, it presents significant disassembly difficulties. When disassembly and maintenance of the motor are required, as shown in the attached diagram... Figure 5 As shown, workers need to use a screwdriver to pry out the air duct housing 10 from the gap 22 on the inner wall of the motor housing 20. The cavity space of the motor housing 20 is small, making the operation difficult. Therefore, we propose a new type of motor that is easy to disassemble. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of motor that is easy to disassemble.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel motor that is easy to disassemble, comprising a housing base, a limiting member, and a locking ring. The housing base is sleeved on the outside of the air duct housing. The limiting member is installed in the side wall groove of the housing base. The inner wall of the housing base is provided with a first limiting protrusion. The limiting member is provided with a second limiting protrusion that cooperates with the first limiting protrusion. The first limiting protrusion is used to limit one end of the air duct housing, and the second limiting protrusion is used to limit the other end of the air duct housing. The locking ring is fastened between the housing base and the limiting member.

[0005] To further elaborate, the outer shell base is provided with a snap-fit ​​part, the limiting member is provided with an outer limiting protrusion, and the locking ring is fastened between the snap-fit ​​part and the outer limiting protrusion.

[0006] To further elaborate, the two limiting members are disposed opposite to each other on the left and right sides of the outer shell base, and the two buckle parts are disposed opposite to each other on the upper and lower sides of the outer shell base.

[0007] To further elaborate, the inner wall edge of the locking ring is provided with a chamfered portion. When the locking ring is engaged with the snap-fit ​​portion of the outer shell base, the chamfered portion of the locking ring slides into the snap-fit ​​portion.

[0008] To elaborate further, the locking ring has protruding wings on both sides, and pushing the protruding wings can push the locking ring to slide into the latching part of the outer shell base.

[0009] The beneficial effects of this utility model are as follows: This utility model adopts a structural design that combines the outer shell base, the limiting component and the locking ring, which greatly improves the convenience of disassembly and reduces the difficulty of operation. The operator only needs to remove the locking ring from the outside to release the relative fixed state between the outer shell base and the limiting component. Then the limiting component can be pulled out from the side wall groove of the outer shell base, and the outer shell base can be separated from the air duct shell, making it convenient to remove the air duct shell of the motor for maintenance.

Detailed Implementation

[0017] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1 To be continued Figure 4As shown, a novel, easily disassembled motor includes a housing base 30, a limiting member 40, and a locking ring 50. The housing base 30 is fitted onto the outside of the air duct housing 10. The limiting member 40 is installed in the side wall slot 31 of the housing base 30. The inner wall of the housing base 30 has a first limiting step 32, and the limiting member 40 has a second limiting step 41 that cooperates with the first limiting step 32. The first limiting step 32 is used to limit one end of the air duct housing 10, and the second limiting step 41 is used to limit the other end of the air duct housing 10. The locking ring 50 is fastened between the housing base 30 and the limiting member 40. The housing base 30, the limiting member 40, and the locking ring 50 together constitute the protective housing of the motor.

[0019] When installing the protective housing on the motor, first fit the air duct housing 10 onto the housing base 30, with one end of the air duct housing 10 abutting against the first limiting protrusion 32 of the housing base 30, and then combine it with the attached... Figure 3 As shown, the limiting member 40 is then installed. The limiting member 40 is inserted into the side wall groove 31 of the housing base 30. The second limiting protrusion 41 of the limiting member 40 abuts against the other end of the air duct housing 10. Finally, the locking ring 50 is put on.

[0020] Combined with appendix Figure 1 and attached Figure 3 As shown, the outer casing base 30 is provided with a latching part 33, and two limiting members 40 are arranged opposite each other on the left and right sides of the outer casing base 30, while the two latching parts 33 are arranged opposite each other on the upper and lower sides of the outer casing base 30. The limiting members 40 are provided with outer limiting protrusions 42, as shown in the attached figure. Figure 1 As shown, the locking ring 50 is fastened between the latching part 33 and the outer limiting protrusion 42, preventing the limiting member 40 from falling off the outer shell base 30 on its own, as shown in the attached diagram. Figure 2 As shown, the two ends of the air duct shell 10 are respectively abutted by the first limiting protrusion 32 of the shell base 30 and the second limiting protrusion 41 of the limiting member 40, and the shell base 30 and the limiting member 40 are in a mutually fixed state.

[0021] As attached Figure 3 As shown, the inner wall edge of the locking ring 50 is provided with a chamfered portion 51. When the locking ring 50 is engaged with the latching portion 33 of the outer casing base 30, the chamfered portion 51 of the locking ring 50 slides into the latching portion 33. The locking ring 50 is provided with protruding wings 52 on both sides. Pushing the protruding wings 52 can push the locking ring 50 to slide into the latching portion 33 of the outer casing base 30.

[0022] When the motor needs to be disassembled and repaired, the locking ring 50 can be removed directly from the outside. Compared with the existing motor, which can only pry out the air duct shell 10 from the inner wall gap 22 of the motor housing 20, the structural design adopted by this utility model is more convenient to disassemble and greatly reduces the difficulty of operation. The operator only needs to remove the locking ring 50 from the outside to release the relative fixed state between the housing base 30 and the limiting member 40. Then the limiting member 40 can be pulled out from the side wall slot 31 of the housing base 30, and the housing base 30 can be separated from the air duct shell 10.
