Description

Technical Field

[0001] The utility model relates to the technical field of motors, and more specifically to a motor air guide component and a motor. Background Art

[0002] When the motor is working, it drives the impeller by rotating, so that the impeller generates wind volume and wind speed, and the wind flows out through the air duct formed by the wind guide blades in the main housing of the motor.

[0003] The air guide blades in the main housing of the existing motor are injection molded as one piece with the main housing and are single-layer air guide blades. However, due to the limitations of the structural principle of the injection molding mold, the blade length of the air guide blades in the axial direction of the main housing cannot exceed the demolding length of the molding mold. If the injection molding length of the blade reaches the axial length limit of the main housing, it will lead to demolding difficulties and low product qualification rate and production efficiency, resulting in increased costs. Therefore, due to the limitations of the mold, the air guide blades of the existing main housing have limitations on guiding the airflow in the air duct, which can easily cause air turbulence in the air duct of the main housing, causing high and low frequency sounds and wind noise, thereby reducing the air outlet effect of the motor. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a motor air guide component and a motor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Further, a first side of the first air guide blade is connected to the inner wall of the outer shell portion, and a second side of the first air guide blade opposite to the first side is connected to the outer wall of the inner shell portion.

[0011] Furthermore, the second air guide member includes an inner ring portion, an outer ring portion, and a plurality of second air guide blades circumferentially arranged between the inner ring portion and the outer ring portion, the space between two adjacent second air guide blades constitutes the second air duct, and the second air guide member is installed as a whole in the air guide member installation space.

[0012] Furthermore, a step portion is provided in the air guide member installation space, and the step portion divides the air guide member installation space into a first installation space and a second installation space, the first installation space is used to arrange the first air guide member, and the second installation space is used to arrange the second air guide member.

[0013] Furthermore, the first air duct is a spiral air duct or a straight air duct, and the second air duct is a spiral air duct or a straight air duct.

Since the second air guide member is a component independent of the main housing, the problem that the height of the air guide channel of the first air guide member integrally formed with the main housing is insufficient compared with the length of the air outlet path of the main housing can be compensated by installing more than one second air guide member, so that the air guide duct formed by the combination of the overlapping first air guide member and the second air guide member can adapt to the length of the air outlet path of the main housing, and guide the airflow from the air inlet to the air outlet, which is conducive to reducing the turbulence of air inside the main housing, and can effectively reduce the high and low frequency sounds and wind noise caused by the turbulence, thereby improving the air outlet effect of the motor.

[0030] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0031] like Figure 1-Figure 5 As shown, an embodiment of the utility model provides a motor air guide assembly, including a main shell 1, a first air guide member 2 and a second air guide member 3, wherein at least one second air guide member 3 is provided, the main shell 1 is provided with an air inlet and an air outlet in its axial direction, the air inlet is located at the bottom of the main shell 1, and the air outlet is located at the top of the main shell 1, the first air guide member 2 is integrally formed and connected to the main shell 1, the second air guide member 3 is assembled and connected to the main shell 1, the first air guide member 2 and the second air guide member 3 are arranged on an air outlet path formed between the air inlet and the air outlet, and the first air guide member 2 and the second air guide member 3 are overlappedly arranged along the axial direction of the main shell 1, the first air guide member 2 is provided with a first air duct 22, the second air guide member 3 is provided with a second air duct 34, and the first air duct 22 is communicated with the second air duct 34.

[0032] Since the second air guide member 3 is a component independent of the main shell 1, the problem that the height of the air guide channel of the first air guide member 2 integrally formed with the main shell 1 is insufficient compared to the length of the air outlet path of the main shell 1 can be compensated by installing more than one second air guide member 3, so that the air guide duct formed by the overlapping first air guide member 2 and the second air guide member 3 can adapt to the length of the air outlet path of the main shell 1, and guide the airflow from the air inlet in the axial direction of the main shell 1 to the air outlet, which is conducive to reducing air turbulence inside the main shell 1, and can effectively reduce the high and low frequency sounds and wind noise caused by the turbulence, thereby improving the air outlet effect of the motor.

[0033] Specifically, the second air guide member 3 may be assembled and connected to the main shell 1 by means of snap-fitting or bonding. In the present embodiment, the second air guide member 3 is assembled and connected to the main shell 1 by bonding.

[0034] like Figure 1 As shown, the main shell 1 includes an outer shell portion 11 and an inner shell portion 12 arranged inside the outer shell portion 11, and an air guide member installation space 13 is formed between the inner wall of the outer shell portion 11 and the outer wall of the inner shell portion 12, and the first air guide member 2 and the second air guide member 3 are arranged in the air guide member installation space 13.

[0035] In this embodiment, the outer shell 11 is a circular ring structure, and the inner shell 12 is a hollow cylindrical structure. It can be understood that the air guide installation space 13 formed between the outer shell 11 and the inner shell 12 is annular in shape. Such a design is more conducive to the assembly of the second air guide 3.

[0036] like Figure 1-Figure 2 As shown, the first air guide 2 includes a plurality of first air guide blades 21 circumferentially arranged in the air guide installation space 13, and the space between two adjacent first air guide blades 21 constitutes a first air duct 22. It can be understood that a plurality of first air ducts 22 are formed on the first air guide 2, and the plurality of first air ducts 22 are circumferentially distributed.

[0037] Specifically, the first side of the first air guide blade 21 is connected to the inner wall of the outer shell 11, and the second side of the first air guide blade 21 opposite to the first side is connected to the outer wall of the inner shell 12. The advantage of this design is that it is conducive to reducing the difficulty of integrally forming the first air guide member 2 and the main shell 1, and the first air guide blade 21 can be used as a connecting component of the outer shell 11 and the inner shell 12 of the main shell 1, and there is no need to design another component to connect the outer shell 11 and the inner shell 12 together, which reduces the use of components and saves manufacturing costs.

[0038] like Figure 3-Figure 5As shown, the second air guide member 3 includes an inner ring portion 31, an outer ring portion 32, and a plurality of second air guide blades 33 circumferentially arranged between the inner ring portion 31 and the outer ring portion 32, and the space between two adjacent second air guide blades 33 constitutes a second air duct 34, and the second air guide member 3 is integrally installed in the air guide member installation space 13. It can be understood that a plurality of second air ducts 34 are formed on the second air guide member 3, and the plurality of second air ducts 34 are circumferentially distributed.

[0039] It should be noted that the number of second air guide members 3 installed can be determined according to actual needs, and can be multiple or one, as long as the air guide duct formed by the combination of the first air guide member 2 and the second air guide member 3 can adapt to the length of the air outlet path of the main shell 1. When multiple second air guide members 3 are installed, the multiple second air guide members 3 are still arranged in an overlapping manner. Generally, in order to facilitate one-piece molding and avoid being restricted by the mold, only one first air guide member 2 is integrally molded on the main shell 1, and the number of second air guide members 3 installed is selected according to actual needs. In this embodiment, a first air guide member 2 is integrally molded on the main shell 1, and a second air guide member 3 is assembled and connected.

[0040] A step portion 131 is provided in the air guide installation space 13. The step portion 131 divides the air guide installation space 13 into a first installation space and a second installation space. The first installation space is used to arrange the first air guide 2, and the second installation space is used to arrange the second air guide 3. In the present embodiment, the step portion 131 is formed by extending outward along the inner wall of the shell portion 11. The step portion 131 serves as a support structure for the second air guide 3. The second air guide 3 is placed above the step portion 131, and the second air guide 3 is installed and fixed by injecting glue between the outer side surface of the outer ring portion 32 of the second air guide 3 and the inner wall of the shell portion 11 of the main shell 1. The first air guide 2 is integrally formed below the step portion 131. The step portion 131 provided supports the second air guide 3 after installation, thereby improving the stability after installation.

[0041] The first air duct 22 is a spiral air duct or a straight air duct, and the second air duct 24 is a spiral air duct or a straight air duct. In one embodiment, the first air duct 22 is a spiral air duct, and the second air duct 34 is a straight air duct; in another embodiment, the first air duct 22 is a straight air duct, and the second air duct 34 is a spiral air duct; in other embodiments, both the first air duct 22 and the second air duct 34 are spiral air ducts or straight air ducts.

[0042] In one embodiment, in order to facilitate manufacturing and save manufacturing costs, the main shell 1, the first air guide member 2 and the second air guide member 3 are all made of plastic material, the main shell 1 and the first air guide member 2 are integrally injection molded, and the second air guide member 3 is separately injection molded.

[0043] like Figure 6As shown, the utility model also provides a motor, including the above-mentioned motor air guide assembly. In addition to the structure of the above-mentioned motor air guide assembly, the remaining structures can be common in existing motors. For example, the motor also includes a housing 4, a fan 5, an impeller 6, a rotor assembly 7, a stator assembly 8, a rear end cover 9 and an upper cover 10. The assembly relationship of these components belongs to the prior art and will not be repeated in this application.

[0044] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
