[0002] The working principle of a vacuum cleaner is to use an electric motor to drive the blades to rotate at high speed, generate negative air pressure in the sealed shell, and absorb dust. With the improvement of the quality of life, vacuum cleaners have gradually entered thousands of households; with the widespread use of vacuum cleaners, consumers have higher and higher requirements for their performance; in daily use, in order to further improve the cleaning efficiency, in addition to increasing the separation efficiency of the dust cup assembly, increasing the suction force can also effectively improve its cleaning efficiency. However, with the increase in suction force, the speed of the motor is also constantly increasing, and the noise it generates also increases accordingly. The high noise makes the vacuum cleaner very noisy when in use, causing discomfort to the human ear, greatly reducing the user's physical experience. Utility Model Content

[0003] Based on this, it is necessary to provide a low-noise vacuum cleaner to address the problem of high noise in existing vacuum cleaners.

[0004] The present application provides a low-noise vacuum cleaner, comprising:

[0005] A host housing, wherein the host housing is provided with an installation cavity, a first air inlet, a first air outlet and a diversion port, and the installation cavity is communicated with the first air inlet, the first air outlet and the diversion port respectively;

[0006] A handle housing, the handle housing being connected to the main body housing, the handle housing being provided with a diversion channel and a third air outlet which are sequentially connected to the diversion port;

[0007] A cyclone dust cup and a dust suction assembly, wherein the cyclone dust cup and the dust suction assembly are both located in the installation cavity, and an air inlet channel is formed inside the cyclone dust cup and the dust suction assembly, and the air inlet channel is respectively connected to the first air inlet, the first air outlet and the diversion port.

[0008] The low-noise vacuum cleaner disclosed in the present application generates a huge airflow in the installation cavity through the dust collection component to form suction. Dust and other debris on the ground enter the installation cavity through the first air inlet, and then enter the air inlet channel formed by the cyclone dust cup and the dust collection component for transmission. Most of the dust and debris are deposited in the cyclone dust cup or at the bottom of the installation cavity under the action of the cyclone dust cup. After the purified air is discharged from the air inlet channel, a part of it is discharged to the outside from the first air outlet, and the other part of the air enters the diversion channel through the diversion port, and is discharged to the outside through the third air outlet. In the vacuum cleaner with the above structure, the air after dust separation can be discharged to the outside from two different paths, avoiding excessive concentrated discharge of air, thereby reducing noise and improving user experience.

[0009] In one embodiment, the cyclone dust cup is provided with a dust collecting chamber, and the dust collecting chamber is connected to the first air inlet; the dust suction assembly includes a first shell and a fan assembly, the first shell is provided with a second air inlet, a power chamber and a second air outlet, the dust collecting chamber, the second air inlet, the power chamber and the second air outlet are connected in sequence to form the air inlet channel, the fan assembly is located in the power chamber, and the second air outlet is respectively connected to the first air outlet and the diversion port.

[0010] The low-noise vacuum cleaner in the above embodiment further defines that the fan assembly is located in the power chamber formed by the first shell, and the fan assembly generates suction when it works. External air and dust and impurities carried by it enter the installation chamber through the first air inlet, and dust is collected in the dust collecting chamber under the action of the cyclone dust cup. The purified air enters the second air inlet and the power chamber in turn, and is discharged from the second air outlet. Since the second air outlet is respectively connected to the first air outlet and the diversion port, the purified air discharged from the second air outlet can be directly discharged to the outside through the first air outlet, or it can enter the diversion channel from the diversion port, and finally be discharged from the third air outlet.

[0011] In one embodiment, the first air outlet is opened on the top of the host shell, the diversion port is opened on the side wall of the host shell, the second air outlet is opened on the side wall of the first shell, and the second air outlet is arranged adjacent to the diversion port.

[0012] The low-noise vacuum cleaner in the above embodiment further defines that the first air outlet is opened at the top of the main body shell, the diverter port and the second air outlet are opened on the side walls of the main body shell and the first shell respectively, and the diverter port is arranged adjacent to the second air outlet, and the second air outlet is arranged opposite to the diverter port, which can avoid that most of the air discharged through the second air outlet is directly discharged to the outside through the first air outlet.

By extending the length of the air duct, the speed and pressure of the airflow can be reduced, thereby reducing the noise generated by the airflow.

[0015] In one embodiment, the cross-section of the diversion channel is L-shaped.

[0016] The low-noise vacuum cleaner in the above embodiment further defines that the cross-section of the diversion channel is L-shaped. Based on the above design, the diversion channel not only extends from top to bottom in the vertical direction, but the bottom of the diversion channel also extends horizontally away from the main body shell, further extending the length of the air duct and better reducing the noise generated by the airflow.

[0017] In one of the embodiments, the vacuum cleaner further includes a battery module, wherein the battery module is located in the diversion channel, and the battery module is electrically connected to the vacuum assembly.

[0018] The low-noise vacuum cleaner in the above embodiment is further limited to include a battery module, which is installed in the diversion channel. A portion of the purified air enters the diversion channel through the diversion port, thereby dissipating the heat of the battery module and reducing the heat of the vacuum cleaner.

[0020] The low-noise vacuum cleaner in the above embodiment further defines that the main housing is composed of an upper housing and a lower housing, wherein a second cavity and a first air inlet are provided on the lower housing, and a cyclone dust cup is installed in the second cavity. After the air and the dust entrained therein enter the second cavity from the first air inlet, the air and dust are separated under the action of the cyclone dust cup; the purified air is then transported to the first cavity formed by the upper housing, and can not only be discharged to the outside through the first air outlet, but also enter the diversion channel through the diversion port; by respectively installing the dust collection assembly and the cyclone dust cup in the first cavity and the second cavity separated from each other, it can be avoided that part of the dust-entrained air that has just been sucked into the installation cavity is not affected by the cyclone dust cup and is directly discharged to the outside.

[0021] In one embodiment, the upper shell and the lower shell are detachably connected.

[0022] In one embodiment, the lower shell includes a shell body and a flip cover, the shell body and the flip cover are combined to form the second cavity, and the flip cover can rotate relative to the shell body.

[0023] The low-noise vacuum cleaner in the above embodiment further defines that the flap can rotate relative to the shell body. Specifically, the flap rotates relative to the shell body to form at least a first position and a second position. When the flap is in the first position, the flap and the shell body are combined to form a second cavity, which can collect dust and impurities; when the flap is in the second position, the cyclone dust cup and the dust and impurities collected in the cyclone dust cup can be dumped.

[0037] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0040] A handle housing 20, which is connected to the main body housing 10, and is provided with a diversion channel 201 and a third air outlet 202 which are sequentially connected to the diversion port 104;

[0041] The cyclone dust cup 30 and the dust suction assembly 40 are both located in the installation cavity 101, and an air inlet channel 401 is formed inside the cyclone dust cup 30 and the dust suction assembly 40, and the air inlet channel 401 is respectively connected to the first air inlet 102, the first air outlet 103 and the diversion port 104.

[0042] The cyclone dust cup 30 can separate dust and air through the cyclone principle, so that the dust is deposited in the cyclone dust cup 30, while the clean air is discharged, effectively separating the dust and preventing clogging.

[0043] The dust collecting assembly 40 can form a strong airflow in the main body housing 10 through the high-speed rotation of the motor, thereby sucking in the dust on the ground through the first air inlet 102 .

[0044] The low-noise vacuum cleaner provided in the present application generates a huge airflow in the installation cavity 101 through the dust collection component 40 to form suction, and dust and other debris on the ground enters the installation cavity 101 through the first air inlet 102, and then enters the air inlet channel 401 formed by the cyclone dust cup 30 and the dust collection component 40 for transmission. Most of the dust and debris are deposited in the cyclone dust cup 30 or at the bottom of the installation cavity 101 under the action of the cyclone dust cup 30. After the purified air is discharged from the air inlet channel 401, a part of it is discharged to the outside from the first air outlet 103, and the other part of the air enters the diversion channel 201 through the diversion port 104, and is discharged to the outside through the third air outlet 202; in the vacuum cleaner with the above structure, the air after dust separation can be discharged to the outside from two different paths, avoiding excessive concentrated discharge of air, thereby reducing noise and improving user experience.

The purified air enters the second air inlet 404 and the power chamber 402 in turn, and is discharged from the second air outlet 403. Since the second air outlet 403 is respectively connected to the first air outlet 103 and the diversion port 104, the purified air discharged from the second air outlet 403 can be directly discharged to the outside through the first air outlet 103, or it can enter the diversion channel 201 from the diversion port 104, and finally be discharged from the third air outlet 202.
