Compared with the prior art, the beneficial effects of the vacuum cleaner provided by the embodiment are basically the same as those of the rear end unit provided by the first embodiment, and are not repeated herein.

Among them, as for the structure of the rear end unit, specifically, referring to fig. 9 to 14, it includes an upper housing 15, a handle 10, a base 18, and a motor assembly, the handle 10 is located between the upper housing 15 and the base 18, the upper housing 15 is connected with the base 18 through the handle 10, that is, one end of the handle 10 is connected with the upper housing 15, and the other end of the handle 10 is connected with the base 18.

In order to facilitate the installation of the motor assembly, the axis A-A of the motor assembly is arranged along the horizontal direction, so that the distribution of the whole force of the dust collector can be optimized, and the comfort degree of a user when the user holds the dust collector is improved.

For the structure of the motor assembly, specifically, the motor assembly comprises a motor shell, a motor body 3 arranged in the motor shell and a shock absorption assembly. For the convenience of motor body 3 in the motor casing and buffer assembly's installation, above-mentioned motor casing is for dividing the body structure, particularly, motor casing includes air inlet end casing 4 and holds casing 5 with the air-out of 4 locks of casing, the inside constitution of air inlet end casing 4 and air-out end casing 5 holds motor body 3 and buffer assembly's cavity, air intake 8 has been seted up to air inlet end casing 4, air outlet 9 has been seted up to air-out end casing 5, air intake 8, cavity and air outlet 9 constitute airflow channel, air outlet 9 is corresponding with exhaust passage 11.

The main parts of the motor for generating vibration and noise are arranged at two ends, so that the cushioning component is of a split structure and comprises an air inlet end cushioning piece 1 and an air outlet end cushioning piece 2. Wherein, air inlet end bradyseism piece 1 is located between air inlet end casing 4 and the 3 air inlet ends of motor body, the outer wall of 3 air inlet ends of motor body is located to air inlet end bradyseism piece 1 cover, the air inlet face and the side of air inlet end bradyseism piece 1 are respectively in the inner wall contact of motor casing, air outlet end bradyseism piece 2 is located between air outlet end casing 5 and the 3 air outlet ends of motor body, the outer wall of the air outlet end of motor body 3 is located to air outlet end bradyseism piece 2 cover, the air outlet end card of motor body 3 is located in the recess of air outlet end bolster, the air inlet face and the side of air outlet end bradyseism piece 2 are respectively in the inner wall contact of motor casing, thereby make motor body 3 erect between air inlet end bradyseism piece 1 and air outlet end brady. Like this, adopt the bradyseism subassembly of components of a whole that can function independently structure, only set up air inlet end bradyseism piece 1 and air-out end bradyseism piece 2 respectively at comparatively strong motor casing air inlet end of vibrations and air-out end and 3 air inlet ends of motor body and air-out end, and need not to wrap up the motor wholly to can improve the exposed heat radiating area of motor body 3 on the basis of effectively bradyseism to motor body 3, thereby improve motor body 3's heat dispersion. In addition, owing to adopt the bradyseism subassembly of components of a whole that can function independently structure, can effectively reduce the consumptive material use amount of bradyseism subassembly to reduce the processing cost increase of above-mentioned motor element and dust catcher.

It should be noted that, because motor body 3 erects between air inlet end bolster and air outlet end bolster, that is to say, motor body 3's the unsettled setting in middle part, motor body 3 can not direct and motor casing contact, consequently, the vibrations in motor body 3 middle part also can not transmit to motor casing.

For example, the inlet end vibration damping member 1 and the outlet end vibration damping member 2 are made of elastic material (e.g., soft rubber) to form an elastic vibration damping member.

In order to reduce the noise generated in the exhaust process of the dust collector, the rear end unit also comprises an auxiliary exhaust duct arranged between the air outlet 9 of the motor shell and the upper shell 15 and an auxiliary exhaust hole 14 arranged at the rear end of the upper shell 15. One end of the auxiliary exhaust passage is communicated with an air outlet 9 of the motor shell, and the other end of the auxiliary exhaust passage is communicated with an auxiliary exhaust hole 14. Compared with the existing dust collector with only a single exhaust passage, the exhaust passage is designed into a double-passage way, gas exhausted by the motor assembly is mainly exhausted out of the dust collector from the exhaust passage 11, and the auxiliary exhaust passage can properly reduce the exhaust amount and the airflow speed of the exhaust passage 11, so that the noise generated in the exhaust process of the dust collector is reduced. It should be noted that the exhaust duct 11 disposed in the handle 10 is used as an exhaust duct, in which the exhaust hole 12 is disposed at the bottom of the handle 10, and is disposed downward, and is far away from the nostril of the user, and the exhausted gas flows downward, so that the pollution of the incompletely filtered dust 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 hand-held dust collector is convenient to hold. The exhaust passage arranged between the air outlet of the motor shell and the upper shell 15 is used as an auxiliary exhaust passage, so that the airflow of the exhaust hole 12 can be properly shared on the basis of avoiding the pollution of incompletely filtered dust to the gas near a user, and the vibration at the exhaust hole 12 is reduced.

It should be noted that the exhaust volume of the exhaust passage 11 is greater than that of the auxiliary exhaust passage, the exhaust volume of the exhaust passage 11 accounts for 60% to 80% of the total exhaust volume (i.e., the total exhaust volume), and the exhaust volume of the auxiliary exhaust passage accounts for 20% to 40% of the total exhaust volume. Illustratively, the exhaust amount of the exhaust passage 11 accounts for 70% of the total exhaust amount (i.e., the total exhaust volume), the exhaust amount of the auxiliary exhaust passage accounts for 30% of the total exhaust amount, and the exhaust amount ratio of the two is controlled to be 7: 3.

in order to allow most of the air discharged from the outlet 9 to enter the air discharge duct 11, the rear end unit further includes a first air guide 16 provided between the outlet 9 and the upper case 15, and the air discharged from the outlet 9 is guided into the air discharge duct 11 in the handle 10 through the first air guide 16. In addition, the first air guide 16 blocks the direct communication between the motor housing air outlet 9 and the auxiliary air outlet 14, and can prevent the air current discharged by the motor housing from directly flowing out of the auxiliary air outlet without passing through the air outlet 11.

In view of shock absorption, the windward surface of the first wind guide 16 is a concave arc structure. This is because, compared with other structures, the concave arc structure does not have a corner, and the gas can be directly and smoothly introduced into the exhaust passage 11 through the concave arc structure, and no disorder is generated at the corner, so that the vibration generated by the first wind guide 16 when the gas interacts with the first wind guide 16 is reduced, and a cushioning effect is achieved.
