Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner products, and in particular to a noise-reducing vacuum cleaner. Background Technology

[0002] Canister vacuum cleaners are a commonly used type of vacuum cleaner. The structure of the canister vacuum cleaner currently in use is shown in patent publication document CN106377205B. This type of vacuum cleaner has a problem when it is working, that is, the exhaust port of this type of vacuum cleaner is directly opened on the top of the cover. This design causes the gas drawn into the canister by the motor to be directly discharged without any buffering or noise reduction structure. Therefore, this type of canister vacuum cleaner will generate a lot of gas noise when it is working. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a noise-reducing vacuum cleaner. By installing a noise-reducing cover on the exhaust port and an external sound-absorbing sponge block on the overflow channel, the air noise during vacuum cleaner operation is reduced through the sound-absorbing effect of the external sound-absorbing sponge block and the noise-reducing cover.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A noise-reducing vacuum cleaner includes a barrel, a support, a soundproof cover, and a motor. The support is mounted on the barrel, the soundproof cover is mounted on the support, and the motor is mounted on the support, with the motor located between the support and the soundproof cover. The barrel has an air inlet. The vacuum cleaner also includes a top cover, a noise-reducing cover, and an external sound-absorbing sponge block. The top cover is mounted on the support, the soundproof cover is located between the support and the top cover, and the top cover has an exhaust port. The noise-reducing cover is mounted on the exhaust port, and an overflow channel is formed between the top cover and the support. The external sound-absorbing sponge block is disposed within the overflow channel.

[0006] In this type of noise-reducing vacuum cleaner, gas enters through the air inlet of the barrel, then passes through the sound insulation cover and the support frame, and exits through the overflow channel and the exhaust port. Therefore, this vacuum cleaner features a noise-reducing cover on the exhaust port. The function of the noise-reducing cover is to change the straight flow of gas from the exhaust port to a curved flow, and further reduce the gas velocity during this process, thereby achieving noise reduction. Simultaneously, for the gas flowing out from the overflow channel, this vacuum cleaner further incorporates an external sound-absorbing sponge block at the overflow channel. This external sound-absorbing sponge block reduces the noise when the gas leaves the overflow channel and further reduces the airflow velocity.

[0007] In summary, this type of noise-reducing vacuum cleaner reduces air noise during operation by installing a noise-reducing cover on the exhaust port and an external sound-absorbing sponge block on the overflow channel, with the help of the sound-absorbing sponge block and the noise-reducing cover.

[0008] Optionally, it also includes a flow guide plate, which is disposed on the bracket and at the outlet of the overflow channel, and the external sound-absorbing sponge block presses the flow guide plate.

[0009] The function of the guide vane is to further form a guide groove at the outlet of the overflow channel, and use the guide groove to guide the gas flow, thereby further reducing the gas flow rate and noise.

[0010] Optionally, there are multiple guide vanes, and the multiple guide vanes are in a parallel and non-contact state.

[0011] Optionally, the noise reduction cover includes a cylinder, fins, and a baffle. The baffle is disposed at one end of the cylinder via the fins. The baffle is not in contact with the cylinder. The cylinder is fitted together with the exhaust port.

[0012] The gas exits from the exhaust port and enters the cylinder, then flows from the cylinder to the baffle, where it is deflected. The deflected gas then exits through the gap between the baffle and the cylinder.

[0013] Optionally, a soundproof cover is also included, which is disposed inside a soundproof enclosure, and the motor is located between the bracket and the soundproof cover.

[0014] Optionally, it also includes an inner sound-absorbing sponge, which is disposed between the sound-absorbing cover and the sound insulation cover, and a soft rubber block is disposed between the sound-absorbing cover and the sound insulation cover.

[0015] The purpose of the soundproof enclosure, soundproof cover, and inner sound-absorbing sponge is to reduce the noise during motor operation. The soft rubber blocks serve to buffer and dampen vibrations between the soundproof enclosure and the soundproof cover.

[0016] Optionally, a filter mesh is provided on the bracket.

[0017] The function of filter mesh is to filter dust.

[0018] Optionally, the bracket is provided with an imported sound-absorbing sponge, which is placed between the motor and the filter cloth.

[0019] Optionally, a shock-absorbing rubber pad is provided between the motor and the bracket.

[0020] Specifically, the shock-absorbing rubber pads are located below the motor, while the sound insulation cover and the silencing cover are located above the motor. The shock-absorbing pads, sound insulation cover, and silencing cover form a motor mounting structure similar to an island. This type of motor island mounting structure can reduce the vibration noise caused by the motor to components such as the barrel and top cover when the motor is working.

[0021] The beneficial effects of this utility model are: by setting a noise-reducing cover on the exhaust port and setting an external sound-absorbing sponge block on the overflow channel, the air noise of the vacuum cleaner during operation is reduced by the sound-absorbing sponge block and the noise-reducing cover.

[0033] As attached Figure 1 ~Appendix Figure 6 As shown, a noise-reducing vacuum cleaner includes a barrel 1, a support 10, a soundproof cover 6, and a motor 2. The support 10 is mounted on the barrel 1, the soundproof cover 6 is mounted on the support 10, and the motor 2 is mounted on the support 10, with the motor 2 located between the support 10 and the soundproof cover 6. An air inlet 101 is provided on the barrel 1. The vacuum cleaner also includes a top cover 5, a noise-reducing cover 7, and an external sound-absorbing sponge block. The top cover 5 is mounted on the support 10, the soundproof cover 6 is located between the support 10 and the top cover 5, and an exhaust port 501 is provided on the top cover 5. The noise-reducing cover 7 is mounted on the exhaust port 501.

[0034] In this type of noise-reducing vacuum cleaner, gas enters through the air inlet 101 of the barrel 1, then passes through the sound insulation cover 6 and the bracket 10, and is discharged through the overflow channel 502 and the exhaust port 501. After the gas is discharged through the overflow channel 502 and the exhaust port 501, a noise-reducing cover 7 is provided on the exhaust port 501. The function of the noise-reducing cover 7 is to change the straight flow direction of the gas flowing out of the exhaust port 501 into a curved flow direction, and further reduce the gas velocity during the process of changing the gas flow direction, thereby achieving noise reduction. Simultaneously, for the gas flowing out from the overflow channel 502, this vacuum cleaner further provides an external sound-absorbing sponge block at the overflow channel 502. The external sound-absorbing sponge block can reduce the noise when the gas leaves the overflow channel 502 and further reduce the airflow velocity.

[0035] In summary, this type of noise-reducing vacuum cleaner reduces air noise during operation by setting a noise-reducing cover 7 on the exhaust port 501 and an external sound-absorbing sponge block on the overflow channel 502, with the help of the sound-absorbing sponge block and the noise-reducing cover 7.

The cylinder 701 is engaged with the exhaust port 501.

[0040] The gas exits from the exhaust port 501 and enters the cylinder 701, then flows from the cylinder 701 to the baffle 703. The baffle 703 then deflects the gas, and the deflected gas exits from the gap between the baffle 703 and the cylinder 701.
