technical field

The utility model relates to a cleaning device, in particular to a fan system of a household sweeper and the household sweeper.

Background technique

With the development of science and technology, various household appliances have gradually entered people's lives, bringing great convenience to people's lives. For example, household sweepers such as vacuum cleaners and sweeping robots are used to clean indoor floors. Household sweepers are more and more popular because they can free their hands, so that people don't need to spend a lot of time cleaning the house, especially for office workers.

Generally, a household sweeper usually includes a fan system, specifically including a dust suction port, an air inlet duct, a dust collection box, a filter device (such as a filter screen) and an air outlet duct. During use, dust and other garbage pass through the dust suction port. Enter the body, and enter the dust box through the air inlet channel, and the filter device is used to filter the dust in the body.

However, most of the air inlet ducts, filter devices and air outlet ducts of the fan systems of current household sweepers are arranged in a "one" shape or approximately "one" shape. This arrangement will not only make the machine itself The size of the filter is large, and more importantly, the inhaled dust or garbage will be directly blown to the filter device and adsorbed on the filter device, thereby causing the blockage of the filter device, and this arrangement basically sucks once and blocks once.

Utility model content

The purpose of the utility model is to solve the problem that the filter device of the household sweeper in the prior art is easily blocked, and provide a fan system of the household sweeper, which can prevent the filter device from being blocked.

In order to achieve the above object, the utility model provides a fan system for a household sweeper on the one hand, the fan system includes a dust collecting device, a flow guide channel and a filter device, and the flow guide channel is sequentially composed of an air inlet channel, the The cavity of the dust collecting device and the air outlet channel are formed, the filter device is arranged on the air outlet channel, and the guide channel has a function to prevent the garbage sucked into the air inlet channel from blowing directly to the filter device up to block the arc of the filter.

Preferably, the fan system includes a fan, one side of the dust collecting device communicates with the air inlet duct, the other side of the dust collecting device communicates with the fan, and the fan communicates with the air outlet The air passage is connected, and the fan is arranged on a side of the arc portion close to the filtering device.

Preferably, the guide channel is U-shaped.

Preferably, the filtering device is a filter screen arranged on the dust collecting device.

Preferably, the filter device adopts a Hypa structure.

The second aspect of the utility model provides a household sweeper. The household sweeper includes a body shell, a dust suction port arranged on the body shell, and the fan system. The dust suction port and the air inlet The channel is connected.

Preferably, the household sweeper includes a floor brush fixed to the housing of the body.

Preferably, the housing of the fuselage is in the shape of a semi-closed cylinder, and the dust collecting device is a cylindrical dust cup.

Preferably, the air outlet duct includes an inlet connected to the fan and an air outlet arranged on the casing of the fuselage and connected to the outside.

Preferably, the household sweeper is a sweeping robot.

Through the above-mentioned technical scheme, since the guide channel has an arc-shaped portion, the dust or garbage sucked into the air inlet duct will not be directly blown and adsorbed to the filter device due to the centrifugal effect of the rotating wind, but will pass through the filter device. Filtration is preceded by a certain rotational transition, which prevents clogging of the filter unit.

Detailed ways

In the present utility model, in the case of no contrary description, the used orientation words such as "up, down, left and right" usually refer to the up, down, left and right shown in the accompanying drawings; "Refers to the inside and outside of the outline of each part itself.

As shown in Figures 1 and 2, according to one aspect of the present invention, the present invention provides a fan system for a household sweeper, the fan system includes a dust collection device 10, a flow guide channel and a filter device 20, the The guide channel is formed by the air inlet channel 30, the cavity of the dust collecting device 10, and the air outlet channel in turn. The filter device 20 is arranged on the air outlet channel. The garbage in the air duct 30 is directly blown onto the filter device 20 to block the arc portion of the filter device 20 .

In the utility model, since the diversion channel has an arc-shaped portion, the dust or garbage sucked into the air inlet duct 30 will not be directly blown and adsorbed to the filter device due to the centrifugal effect of the rotating wind, but will pass through After a certain rotation, the filter is filtered through the filter device, which can prevent the blockage of the filter device.

Further, the fan system includes a fan, one side of the dust collecting device 10 communicates with the air inlet duct 30, and the other side of the dust collecting device 10 communicates with the fan, and the fan communicates with the air outlet duct , the fan is arranged on a side of the arc portion close to the filter device 20 . In this way, the garbage or dust can be sucked into the air inlet duct 30 by the action of the fan, and then filtered through the filter device after the rotation transition of the arc portion of the flow guiding channel.

Wherein, the shape of the guide channel can be selected according to the actual situation. In this embodiment, in order to reduce the overall size of the household sweeper, the guide channel is U-shaped, and the direction of the arrow shown in Figure 2 is The direction of garbage or dust. It should be noted that the U-shape here is not a strict U-shape in the geometric sense, and the U-shape mentioned in this embodiment includes U-shape and near U-shape.

In addition, the structure of the filter device can be selected according to the actual situation. For example, in this embodiment, the filter device 20 is a filter screen arranged on the dust collecting device 10 . Preferably, the filtering device 20 adopts a Hypa structure.

According to another aspect of the utility model, the utility model also provides a household sweeper, the household sweeper includes a body shell 50, a dust suction port provided on the body shell 50, and the above-mentioned fan system. The dust port communicates with the air inlet channel 30 . In this way, rubbish or dust enters the air inlet duct 30 through the dust suction port, and then rotates and transitions through the arc portion of the guide channel, and finally filters through the filter device, and discharges clean air through the air outlet duct, as shown in Figure 2 indicated by the arrow direction. The household sweeper may be a sweeping robot.
