For example, the chinese patent publication No. ZL201180061325.5 (publication No. CN 103269630B) discloses a vacuum cleaner having a moving head which moves back and forth on a surface to be cleaned, the moving head having a front end and a rear end, wherein the moving head further has: a rotating brush disposed in a brush chamber at the forward end of the travelling head, the brush chamber having an opening through which a portion of the rotating brush protrudes, the opening and the rotating brush spanning substantially the full width of the travelling head; a fan blade; a motor for driving the rotary brush and the fan blade; a removable dirt collection chamber spanning substantially the full width of the travelling head; a dust filter located between the dust collection chamber and the fan blades, the dust filter also spanning substantially the full width of the travelling head; and an airflow duct connecting the brush chamber and the dirt-collection chamber, the forward end of the airflow duct being substantially tangential to the rotatable brush, the airflow duct spanning substantially the full width of the travelling head throughout the entire length of the airflow duct. Realized the clearance of treating the cleaning surface in the above-mentioned patent, however, the dust that gets into in the dust collecting chamber only filters through the dust catcher, and its separation effect is poor to lead to the dust catcher to block up easily, influence separation efficiency, and need change the dust catcher constantly.

Disclosure of Invention

A first technical problem to be solved by the present invention is to provide a separation module for a cleaning machine, which can improve the separation capacity by reducing the fluid flow speed to settle the particles with higher specific gravity.

The second technical problem to be solved by the invention is to provide a cleaning machine for both dry and wet purposes.

The technical scheme adopted by the invention for solving the first technical problem is as follows: a separation module for a cleaning machine comprises

The air conditioner comprises a shell, a fan and a fan, wherein a cavity is formed in the shell, and the cavity is provided with an air inlet and an air outlet which is communicated with the air inlet in a fluid mode;

it is characterized by also comprising

A baffle disposed in the chamber and located on a fluid flow path between the air inlet and the air outlet, the baffle and the air inletThe distance between the planes of the air ports is L ₁ The distance between the baffle and the plane where the air outlet is positioned is L ₂ Wherein, the distance L ₁ And a spacing L ₂ Satisfies the following conditions: l is a radical of an alcohol ₁ ≤L ₂ 。

Preferably, the distance L2 and the distance L1 satisfy: l is ₂ ＝4L ₁ . So, the air current such as dust, the air that get into through the air intake collides and the gathering with the baffle earlier, and at this moment, the granule that proportion is big more does benefit to and subsides, because the interval between baffle and the air outlet is great, and the volume increases promptly, the air current flow velocity can slow down, has reduced the great granule of proportion that the deposit got off and has been inhaled the emergence probability of air outlet department, has improved the separation effect.

In order to improve the separation capacity, a first opening communicated with the accommodating cavity is formed in the side wall of the shell, an air inlet channel is arranged in the accommodating cavity, an inlet of the air inlet channel is connected with the first opening, and an outlet of the air inlet channel is the air inlet. The design of the air inlet channel increases the agglomeration of dust, particles and air entering through the first opening, and the dust, the particles and the air are easier to settle after the baffle is impacted, so that the separation effect is improved; in addition, after the subsequent separation module is dumped, the garbage in the volume is prevented from being guided to the upstream module through the first opening.

Preferably, the central line of the air inlet channel satisfies the following conditions: y =0.4203x ³ -3.8481x ² +4.8816x +54.14 (x is more than or equal to 0 and less than or equal to 36). Therefore, the air inlet channel gradually extends downwards along the fluid flow path and then extends in a basically horizontal arrangement mode, so that further agglomeration and collision of the mixed air flow in the air inlet channel are increased, and the flow speed of the mixed air flow is reduced.

In order to further improve the separation capacity, a second opening communicated with the accommodating cavity is formed in the side wall of the shell, an air outlet channel is arranged in the accommodating cavity, the baffle is located between the air inlet channel and the air outlet channel, the outlet of the air outlet channel is connected with the second opening, and the inlet of the air outlet channel is the air outlet. The design of the air outlet channel can ensure that dust or particles with higher specific gravity in the settled mixed airflow are settled and separated again in the air outlet channel, thereby improving the separation and filtration effects; in addition, after the subsequent separation module is dumped, the garbage in the volume is prevented from being guided to the downstream module through the second opening.

Preferably, the center line of the air outlet channel satisfies: y = -0.0794x ⁴ +0.691x ³ -0.3177x ² -2.9466x +38.195 (91. Ltoreq. X.ltoreq.127). So, air-out passageway upwards extends after extending along the basic level of fluid flow path gradually, so, relies on inertia to enter into behind the air-out passageway with the inner wall of air-out passageway collision through the air current after subsiding, the relative great dust of proportion or granule separate once more, have increased the separation effect.

In order to again effect separate filtration of the air flow discharged into the downstream module, a filter element is included, which is located downstream of the second opening along the fluid flow path.

Preferably, the baffle is vertically arranged, and a gap is reserved between the bottom of the baffle and the bottom wall of the accommodating cavity. Thus, the mixed gas flows collide with the baffle plate and then the gas flows out through the interval after sedimentation.

Preferably, the bottom edges of the air inlet and the air outlet are both located above the bottom edge of the baffle, or the bottom edges of the air inlet and the air outlet and the bottom edge of the baffle are located on the same horizontal plane. In this way, substantially all of the air flowing out through the air inlet of the chamber impinges on the baffle for separation.

In order to further reduce the fluid flow speed, the baffle is convexly provided with a convex part on the side facing the air inlet. The presence of the protrusions causes a rapid attenuation of the air flow impacting with the baffle, allowing a majority of the particles and/or water to settle; and if water exists, dust, particles and water are condensed through the convex part and then drop into the bottom of the containing cavity, so that splashing of the water is reduced.

Preferably, the convex parts are strip-shaped and transversely arranged, the convex parts are arranged in groups, and each group is provided with a plurality of convex parts which are arranged at intervals up and down.

In order to enable the impacted fluid to flow downwards into the containing cavity along the baffle, at least two groups of the convex parts are arranged at intervals along the transverse direction of the baffle, and a liquid guide flow channel extending along the vertical direction is formed between every two adjacent groups of the convex parts.

The technical scheme adopted by the invention for solving the second technical problem is as follows: a cleaning machine with above-mentioned separation module which characterized in that: the air purifier is characterized by further comprising a cleaning module and a fan, the separating module is located between the cleaning module and the fan along an airflow flow path, an air inlet of the separating module is communicated with an outlet of the cleaning module, and an air outlet of the separating module is communicated with an inlet of the fan.

Preferably, the cleaning machine is a sweeper.

Compared with the prior art, the invention has the advantages that: the baffle plate in the separation module for the cleaning machine is positioned on a fluid flow path between the air inlet and the air outlet of the cavity, can block airflow flowing towards the air outlet, reduces the flow speed of mixed airflow and reduces splashing, so that particles and/or water with large specific gravity can be settled, the distance between the baffle plate and the plane where the air inlet is positioned is not more than the distance between the baffle plate and the plane where the air outlet is positioned, the mixed airflow flowing out from the air inlet directly impacts the baffle plate to be settled, the airflow after settlement separation slows down the flow speed of the airflow due to subsequent volume increase, the particles with large specific gravity after settlement are prevented from being sucked into the air outlet to influence the separation effect, and the whole separation effect is better.
