Problems solved by technology

With the upgrading of technology, the power of the motor of the handheld vacuum cleaner is getting higher and higher, and the corresponding suction is getting stronger and stronger. The noise generated by the high-speed rotation of the motor is also getting louder. The lack of a perfect noise reduction structure makes the user experience Not good; at the same time, in order to match the high-power motor, the battery requirements of the vacuum cleaner are getting higher and higher
The quality and capacity of the battery directly determine the battery life of the cordless vacuum cleaner. A battery pack with good quality and large capacity can definitely bring a longer battery life for the cordless vacuum cleaner. big problem

Embodiment 1

[0039] As shown in the figure, the present invention provides a noise reduction and heat dissipation structure, including a motor case 3 , an air outlet 5 , a battery case 6 , a motor 8 , a battery pack 9 , and ribs 10 .

[0040] The motor 8 is arranged in the motor casing 3 ; the battery pack 9 is arranged in the battery casing 6 .

[0041] The battery case 6 has and only has two openings, one is the air inlet 6-1, and the other is the air outlet 6-2;

[0042] The battery pack 9 is a hollow ring structure; the inside of the battery case 6 is provided with a plurality of ribs 10, and the ribs 10 limit the circumferential direction and the radial direction of the battery pack 9, and there is a gap between the battery pack 9 and the battery case 6. Gap: one end of the hollow channel of the battery pack 9 abuts against the motor 8 , and the other end communicates with the gap between the battery pack 9 and the battery case 6 .

[0043] The hollow channel and the gap of the batte...

Embodiment 2

[0048] On the basis of Embodiment 1, the motor inner shell 4 is added, the motor 8 is wrapped by the motor inner shell 4, and the motor inner shell 4 is wrapped by the motor shell 3, the first and second interfaces 4-1, 4-2 of the motor inner shell Corresponding to the sealed connection of the dust collection cup 2 and the first interface 6-1 of the battery case respectively, the structure of the motor inner case limits the direction of the airflow when passing through the motor part.

[0049] At the same time, a handle air channel 7-1 is added inside the handle, and the air outlet 5 is arranged at the bottom of the handle 7, so that one end of the handle air channel 7-1 is connected to the air outlet 5, and the other end is connected to the battery pack 9 and the battery case 6 the gap between

[0050] The airflow that flows out through the gap between the battery pack 9 and the battery case 6 passes through the second interface 6-2 of the battery case, then passes through th...

Abstract

The invention relates to the field of dust collectors. The invention discloses a noise reduction and heat dissipation structure and a dust collector. The noise reduction and heat dissipation structurecomprises a motor shell, a motor, a battery shell and a battery pack, wherein the battery pack is located at one end of the motor, the battery pack is of a hollow annular structure, and a gap is formed between the battery pack and the battery shell; an exhaust port is formed between the motor shell and the battery shell; a hollow channel of the battery pack and the gap form an airflow channel, and an outlet of the airflow channel is the exhaust port. According to the technical scheme, the airflow channel is greatly lengthened, and noise generated by friction between air flow at an air outletof the motor and the air outlet can be lowered; the airflow channel is located in the middle and on the periphery of the battery pack, high-speed airflow achieves a good heat dissipation effect on thebattery pack when passing through the airflow channel, and the temperature of the battery pack is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a noise reduction and heat dissipation structure and a vacuum cleaner thereof. Background technique [0002] With the advancement of science and technology, more and more portable household appliances have entered thousands of households. Handheld cordless vacuum cleaners are favored by more and more families because of their light weight, small size, flexible operation, and can be used for cleaning in various environments. With the upgrading of technology, the power of the motor of the handheld vacuum cleaner is getting higher and higher, and the corresponding suction is getting stronger and stronger. The noise generated by the high-speed rotation of the motor is also getting louder. The lack of a perfect noise reduction structure makes the user experience Not good; at the same time, in order to match the high-power motor, the vacuum cleaner has higher a...
