In addition, because the cushioning component with the split structure is adopted, the consumption of consumables of the cushioning component can be effectively reduced, and therefore the processing cost of the motor component and the dust collector is reduced.
It should be noted that, because the motor body 3 is erected between the air inlet end buffer member and the air outlet end buffer member, that is, the middle part of the motor body 3 is suspended, the motor body 3 cannot directly contact with the motor housing, and therefore, vibration in the middle part of the motor body 3 cannot be transmitted to the motor housing.
For example, the air inlet end cushioning member 1 and the air outlet end cushioning member 2 may be made of an elastic material (e.g., soft rubber).
In order to facilitate the installation of the motor body 3 and the buffer assembly in the motor housing, the motor housing can also be of a split structure, specifically, the motor housing can comprise an air inlet end housing 4 and an air outlet end housing 5 buckled with the air inlet end housing 4, the air inlet end housing 4 and the air outlet end housing 5 form a cavity for accommodating the motor body 3 and the buffer assembly, the air inlet end housing 4 is provided with an air inlet 8, the air outlet end housing 5 is provided with an air outlet 9, and the air inlet 8, the cavity and the air outlet 9 form an air flow channel. Therefore, when the motor body 3 and/or the buffer component are installed or replaced, the air inlet end shell 4 and the air outlet end shell 5 can be separated, and then the motor body 3 and/or the buffer component are installed or replaced, so that the operation is simple and convenient.

Example two
The present embodiment provides an exhaust assembly for a vacuum cleaner, see fig. 6, comprising a motor assembly provided in the first embodiment, which is disposed above the vacuum cleaner handle 10.
Compared with the prior art, the exhaust assembly of the dust collector provided by the embodiment has the same beneficial effects as the motor assembly provided by the first embodiment, and is not described in detail herein.
It will be appreciated that in order to achieve the exhaust function of the above-described exhaust assembly, it may further include a main exhaust duct 11, a main exhaust duct 12, an auxiliary exhaust duct 13, and an auxiliary exhaust duct 14. The main exhaust passage 11 is arranged in the handle, the main exhaust hole 12 is arranged at the bottom of the handle, one end of the main exhaust passage 11 is communicated with the air outlet of the motor shell, and the other end of the main exhaust passage 11 is communicated with the main exhaust hole 12; the auxiliary exhaust duct 13 is arranged between the air outlet of the motor shell and the upper shell 15 of the dust collector, the auxiliary exhaust hole 14 is arranged at the rear end of the upper shell 15 of the dust collector, one end of the auxiliary exhaust duct 13 is communicated with the air outlet of the motor shell, and the other end of the auxiliary exhaust duct is communicated with the auxiliary exhaust hole 14. This is because, in the prior art, the vacuum cleaner has only a single exhaust passage, and the flow rate of the air is too fast when passing through the inside of the exhaust passage, so that the vacuum cleaner generates a relatively large noise in the exhaust process. It should be noted that, the exhaust passage provided in the handle is taken as the main exhaust passage 11, that is, the main exhaust hole 12 is provided at the bottom of the handle, and is provided downwards, far away from the nostril of the user, and the exhausted gas flows downwards, so that the pollution of the dust which is not filtered completely to the gas near the user can be reduced; meanwhile, the downward flowing gas can generate upward reaction force on the dust collector, so that the hand feeling weight of a user is reduced, and the dust collector is convenient to hold. The exhaust passage between the air outlet of the motor housing and the upper housing 15 of the dust collector is used as the auxiliary exhaust passage 13, so that the air flow of the main exhaust hole 12 can be properly shared on the basis of avoiding pollution of incompletely filtered dust to gas nearby a user, and vibration at the main exhaust hole 12 is reduced.
In order to further reduce the vibration at the main exhaust hole 12, the main exhaust passage 11 may be inclined, so that the flow path length and flow time of the air flow in the main exhaust passage 11 can be increased, the air flow is affected by the flow resistance when flowing in the main exhaust passage 11, the flow speed thereof is gradually reduced, the longer the flow path and flow time are, the larger the reduction amplitude is, and therefore, the obliquely arranged main exhaust passage 11 can further reduce the flow speed of the air flow flowing through the main exhaust hole 12, thereby reducing the vibration at the main exhaust hole 12.
It should be noted that, the exhaust amount of the main exhaust passage 11 is greater than the exhaust amount of the auxiliary exhaust passage 13, the exhaust amount of the main exhaust passage 11 may account for 60% -80% of the total exhaust amount (i.e., total exhaust volume), and the exhaust amount of the auxiliary exhaust passage 13 may account for 20% -40% of the total exhaust amount. For example, the exhaust amount of the main exhaust passage 11 may be 70% of the total exhaust amount (i.e., the total exhaust volume), the exhaust amount of the auxiliary exhaust passage 13 may be 30% of the total exhaust amount, and the exhaust amount ratio of the two may be controlled at 7:3.
in order to make one part of the air flow discharged from the motor assembly be guided to the main air discharge passage 11 and the other part be guided to the auxiliary air discharge passage 13, the air discharge assembly may further comprise an air guide assembly, through which one part of the air flow discharged from the motor assembly can be guided to the main air discharge passage 11 and the other part is guided to the auxiliary air discharge passage 13, thereby realizing dual-channel air discharge.
Specifically, the air guiding assembly includes a first air guiding member 16 disposed between the air outlet of the motor housing and the auxiliary air outlet 14, and a second air guiding member 17 disposed below the air guiding member, where the second air guiding member 17 is disposed on a windward surface at a connection portion of the main air outlet 11 and the auxiliary air outlet 13, and an air outlet direction of the second air guiding member 17 is directed toward the auxiliary air outlet 13. Wherein, the first air guide piece 16 blocks the direct communication between the air outlet of the motor housing and the auxiliary air exhaust hole 14, so that the air flow exhausted by the motor housing can be prevented from directly flowing out of the auxiliary air exhaust hole 13 without passing through the main air exhaust hole 11. The air flow is guided to the direction of the main exhaust duct 11 by the first air guide 16, and then, when passing through the junction of the main exhaust duct 11 and the auxiliary exhaust duct 13, the air flow contacts the second air guide 17, and a certain amount of refraction is generated by the air flow by the second air guide 17, so that a part of the air flow can be guided to the auxiliary exhaust duct 13.
In order to further adjust the direction of the air flow, so that the air flow can be guided to the main exhaust duct 11 after passing through the first air guiding member 16, the angle between the first air guiding plate and the air inlet axis of the motor housing may be controlled to be 80 ° to 100 °, and for example, the angle may be 90 ° to 93 °.
Illustratively, the second air guiding member 17 has a convex arc shape, and when the air flow contacts with the arc surface of the second air guiding member 17, the air flow is smoothly guided into the auxiliary air exhaust duct 13 and finally exhausted from the auxiliary air exhaust duct 14.
In view of the fact that the path of the air flow flowing into the auxiliary exhaust duct 13 is complicated and is not smooth, in order to properly increase the amount of the air discharged from the auxiliary exhaust duct 14, the auxiliary exhaust duct 14 may be formed in a plurality of shapes, specifically, the plurality of auxiliary exhaust ducts 14 may be arranged in a vertical direction, and the auxiliary exhaust duct 14 may be formed in a long-strip shape, that is, both sides of the auxiliary exhaust duct 14 extend toward both side wall surfaces of the rear end surface of the cleaner upper case 15, respectively, thereby forming a long-strip-shaped hole. In this way, the exhaust area of the auxiliary exhaust hole 14 is large, and the air flow introduced into the auxiliary exhaust hole 13 can be exhausted from any part of the auxiliary exhaust hole 14 to the outside of the cleaner, so that the exhaust amount of the auxiliary exhaust hole 14 can be appropriately increased.
Considering that the air exhausted from the auxiliary exhaust hole 14 may be directly blown onto the user, if the flow rate of the air flow is too high, the user may feel the impact of the air flow, so as to reduce the user experience, in order to further reduce the flow rate of the air flow exhausted from the auxiliary exhaust hole 14, the side wall of the auxiliary exhaust hole 14 may be provided with a plurality of buffer grooves, and the cross-sectional area of the buffer grooves gradually increases along the direction from the air inlet end to the air outlet end of the auxiliary exhaust hole 14. Therefore, the flow speed of the air flow can be further reduced, so that a user basically does not feel the impact of the air flow, and the user experience is improved.
Considering that the impact between the air flow and the second air guiding member 17 is strong when the air flow passes through the connection part of the main air exhaust passage 11 and the auxiliary air exhaust passage 13, large vibration and noise are easy to generate, the second air guiding member 17 can also be made of an elastic material (such as soft rubber) so that the air flow guiding effect can be realized through the second air guiding member 17, the shaking of the handle caused by the vibration of the motor can be avoided, and the noise reduction effect can be also achieved.
Example III
The present embodiment provides a vacuum cleaner, and referring to fig. 7, the vacuum cleaner includes a front end unit and an exhaust assembly provided in the second embodiment in order along an air intake direction of the vacuum cleaner.
Compared with the prior art, the beneficial effects of the dust collector provided by the embodiment are basically the same as those of the exhaust assembly provided by the embodiment two, and are not described in detail herein.
It is to be understood that the above-mentioned dust collector can also include the dust collector stores pylon, see fig. 8 through 9, and the dust collector stores pylon includes body and connecting piece, and the connecting piece is located on the body, and the protrusion forms in the body and hangs and establish the structure, and the base of dust collector host computer is hung and is located on the connecting piece, and it is to be understood that need set up corresponding spread groove on the base through arranging the connecting piece in the spread groove, realizes the connection of base and dust collector stores pylon. The hanging structure is formed by the connecting pieces, the base is hung on the hanging structure, the size of the hanging structure can be effectively reduced, the weight and cost of the hanging structure are reduced, and the integral structure of the dust collector is further simplified.
Illustratively, the length of the above-described cleaner hanger may be 135-145 mm (e.g., 140.5 mm), and the width of the cleaner hanger may be 60-65 mm (e.g., 62.5 mm).
Specifically, the connector may include a connection portion 22 and a hanging portion 23, wherein the hanging portion 23 is connected to the body through the connection portion 22, that is, the bottom end of the connection portion 22 is connected to the body, and the top end of the connection portion 22 is connected to the hanging portion 23. It will be appreciated that, in order to form the hanging structure, the edge of the hanging portion 23 (e.g. the upper side, the left side and/or the right side of the hanging portion 23) needs to protrude outside the connecting portion 22, and when the connecting slot on the host chassis is hung on the hanging member, the edge of the hanging portion 23 can be clamped in the connecting slot, so as to better limit the host chassis, and ensure that the host chassis cannot fall out of the connecting slot.
As for the structure of the body, it may specifically include an intermediate plate 24 and end plates 25 provided at both ends of the intermediate plate 24, the intermediate plate 24 being located between the two end plates 25, and the connecting member being provided on the intermediate plate 24.

This is because the height of the end plate 25 is lower than the height of the intermediate plate 24, the gap between the end plate 25 and the connecting portion 22 is larger than the gap between the intermediate plate 24 and the connecting portion 22, and the base can be more conveniently hung on the connecting member when the base is connected to the intermediate plate 24. Meanwhile, when the body needs to be fixedly connected with the mounting surface through the screw, the screw can be arranged on the end plate 25, the screw penetrates through the end plate 25 to be connected with the mounting surface, the thickness of the end plate 25 is properly reduced, and the size of the required screw can be reduced. In addition, the end plate 25 at the lower end can be spaced a certain distance, so that the base can rotate counterclockwise by a certain angle relative to the plane of the middle plate 24 under the action of gravity, and further, the connecting groove can be in close contact with the connecting piece.
