Fig. 1 shows the decomposition texture schematic diagram of the embodiment of the electric machine assembly of dust catcher according to the present utility model.Such as Shown in Fig. 1, the electric machine assembly of the dust catcher of the present embodiment includes:Shell 10 and wind turbine portion 20.Wherein, shell 10, which has, accommodates Chamber is provided with the air entry 11 being connected to accommodating chamber and the first gas outlet 12 on shell 10.Wind turbine portion 20 is arranged in accommodating chamber, The import in wind turbine portion 20 is correspondingly arranged with air entry 11, wherein passes through the first outlet from the air-flow of the outlet outflow in wind turbine portion 20 Mouth 12 drains into outside shell 10.
Using the technical solution of the present embodiment, the electric machine assembly of dust catcher includes shell 10 and wind turbine portion 20, wind turbine portion 20 settings are in the housing 10.Shell 10 forms one layer of separation layer in the periphery in wind turbine portion 20, the vibrations warp for making wind turbine portion 20 generate The decaying for crossing shell 10 is transferred to the body of dust catcher again, meanwhile, so that the noise that wind turbine portion generates is passed through the anti-of shell 10 Penetrate and cut down again the body of the outer wall of the first gas outlet 12 by shell 10 or shell 10 outflow dust catcher.And then it realizes The purpose for reducing the noise generated when dust catcher operation, improves user experience.
Further, Fig. 2 shows the schematic cross-sectional views of the electric machine assembly of the dust catcher of Fig. 1.Such as Fig. 1 and Fig. 2 institutes Show, the shell 10 of the present embodiment includes first shell 13 and second shell 14, and first shell 13 and second shell 14 are connected with each other To form accommodating chamber, air entry 11 is arranged in first shell 13, and the first gas outlet 12 is arranged in second shell 14.First shell Body 13 and the combination of second shell 14 form shell 10, are on the one hand convenient for the molding and assembling of shell 10, on the other hand seperated shell Body 10 is conducive to alleviate the vibrations that wind turbine portion 20 generates, and reduces the vibrating effect for being transferred to dust catcher body.
Further, as shown in Fig. 2, in the present embodiment, the first gas outlet 12 be arranged second shell 14 side wall and The junction of bottom wall.Compared with the first gas outlet to be set up directly on to the side wall of shell or the scheme of bottom wall, above structure exists The path length for exporting to the first gas outlet from wind turbine portion is extended to a certain extent, thereby reduces the flowing velocity of air, Improve the noise reduction of electric machine assembly.
In other figs. in unshowned embodiment, flow-guiding structure can be set on the inner wall of the housing, so that air Can accurately the first gas outlet be flowed to according to the direction and mode of designer's anticipation.
Further, Fig. 3 shows the A-A of the electric machine assembly of the dust catcher of Fig. 2 to schematic cross-sectional view;Fig. 4 is shown The overlooking structure diagram of the second shell of Fig. 1.As shown in Figures 1 to 4, in the present embodiment, it is arranged in first shell 13 Fluted 15, compatible with groove 15 raised 16 are provided in second shell 14.Specifically, in the present embodiment, first shell Body 13 is located at the top of second shell 14, the bottom wall of the opening of groove 15 towards second shell 14.First shell 13 and second shell Body 14 stretches into the protrusion 16 of second shell 14 when assembling in the groove 15 of first shell 13, and groove 15 and protrusion 16 match limit Determine the relative movement of first shell 13 and second shell 14, while can also be by being spirally connected or other connection types improve first The fixed effect of shell 13 and second shell 14.
It, can be by the opening of groove towards second shell it should be noted that in other embodiment not shown in the figure The side wall of body is arranged, and the corresponding side wall by protrusion towards first shell is arranged, using first shell and second shell material from The elasticity of body realizes the fixation of the two.
It should be further noted that in other embodiment not shown in the figure, first shell and second shell can With using other assembly methods.For example, substituting the connection side of two-piece unit in above-described embodiment by the way of split left and right Formula, to meet structural requirement in practical dust catcher.Either increase shell seperated quantity for example by shell be divided into three parts or Four parts are to optimize the moulding process of shell.Shell it is each it is seperated between connection type can be according to the specific side of molding of shell Formula or combination accordingly arrange the direction and position of groove and protrusion.
Further, as shown in Figures 2 and 3, in the present embodiment, between the inner wall of the outer wall and shell 10 in wind turbine portion 20 With distance.Gap between the outer wall and the inner wall of shell 10 in wind turbine portion 20 forms air duct, enables air to flow to along air duct First gas outlet.
Further, as shown in Figure 1 to Figure 3, it is provided with bolster 30 between the shell 10 and wind turbine portion 20 of the present embodiment. Specifically, bolster 30 includes that the first bolster 31 between the roof and the top in wind turbine portion 20 of shell 10 is arranged and sets Set the second bolster 32 between the bottom wall and the bottom in wind turbine portion 20 of shell 10.First bolster 31 and the second bolster 32 The vibrations that wind turbine portion 20 is transmitted to shell 10 are further weakened, noise reduction is improved.
Present invention also provides a kind of dust catcher, the dust catcher (not shown) according to the present embodiment includes motor group Part, electric machine assembly are the electric machine assembly of above-mentioned dust catcher.The dust catcher of the present embodiment has the advantages that low noise.
Further, dust catcher includes casing, and shell 10 is set in casing, and casing has the second gas outlet, at least portion There is distance, so that between the inner wall of casing and the outer surface of shell 10 between the outer surface of shell 10 divided and the inner wall of casing With gap, the second gas outlet is connected by gap with the first gas outlet 12.The inner wall of casing and the outer surface of shell 10 it Between gap avoid the vibrations of shell 10 from being transferred directly to casing, improve noise reduction.In addition, buffering can also be placed in gap Part further increases buffering noise reduction.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects:
The electric machine assembly of dust catcher includes shell and wind turbine portion, and wind turbine portion is arranged in the housing.Shell is in wind turbine portion Periphery forms one layer of separation layer, and the vibrations that wind turbine portion generates is made to be transferred to the body of dust catcher again by the decaying of shell, meanwhile, Enable the noise that wind turbine portion generates by the reflection of shell and cuts down again through the outer of the first gas outlet of shell or shell Wall spreads out of the body of dust catcher.And then the purpose for reducing the noise generated when dust catcher operation is realized, improve user experience.
