Problems solved by technology
In the related technology, the vacuum cleaner does not use any noise reduction and silencing means in the dust collection part. The high-speed and energy-concentrated airflow quickly passes through the filter Hypa, and hits the upper dust cup vertically. In addition, the forced airflow is 90° The steering makes most of the energy concentrate on the dust cup cover. In addition, due to the wall thickness and single-layer structure, as well as the limitation of space height, the washing noise is further amplified, which increases the noise during the use of the vacuum cleaner. Affect the comfort of use

Embodiment Construction
[0025] Refer below figure 1 and figure 2 The dust cup upper cover assembly 100 of the vacuum cleaner according to the embodiment of the present invention is described.
[0026] like figure 1 and figure 2 As shown, the dust cup upper cover assembly 100 of the vacuum cleaner according to the embodiment of the present invention includes: the dust cup upper cover 1 , the inner cover 4 of the dust cup upper cover, the sound-absorbing member 3 and the sound-absorbing partition 2 .
[0027] Specifically, the dust cup upper cover inner cover 4 is arranged on the inner side of the dust cup upper cover 1 (for example figure 1 The lower side of the dust cup upper cover 1 shown in ), the dust cup upper cover inner cover 4 is provided with a sound-absorbing hole 41, the sound-absorbing hole 41 can absorb the sound wave of the frequency corresponding to it, thereby can play the effect of noise reduction.
[0028] The silencing element 3 is arranged on the outer surface of the inner co...

The invention discloses a dust cup upper cover assembly of a dust collector. The dust cup upper cover assembly of the dust collector comprises a dust cup upper cover, a dust cup upper cover inner cover, a muffling part and a muffling partition plate, wherein the dust cup upper cover inner cover is arranged on the inner side of the dust cup upper cover, muffling holes are formed in the dust cup upper cover inner cover, the muffling part is arranged on the outer side face of the dust cup upper cover inner cover and covers the muffling holes, and the muffling partition plate is arranged on the inner side of the dust cup upper cover and covers the outer side face of the muffling part. According to the dust cup upper cover assembly of the dust collector, scouring noise of airflow can be reduced, energy of the airflow can be absorbed, and the flow velocity of the airflow can be decreased; therefore, the overall noise of the dust collector is reduced, and the use comfort of a user is improved.
Description
technical field [0001] The invention relates to the technical field of cleaning appliances, in particular to a dust cup upper cover assembly of a vacuum cleaner. Background technique [0002] With the continuous development of the vacuum cleaner industry, people's requirements for vacuum cleaners are getting higher and higher, and the requirements for the experience in use are becoming more and more strict, especially the sound generated when the machine is working, which has become the primary condition for people to buy vacuum cleaners one. In the related technology, the vacuum cleaner does not use any noise reduction and silencing means in the dust collection part. The high-speed and energy-concentrated airflow quickly passes through the filter Hypa, and hits the upper dust cup vertically. In addition, the forced airflow is 90° The steering makes most of the energy concentrate on the dust cup cover. In addition, due to the wall thickness and single-layer structure, as we...
