Referring to fig. 2, the dust box with the filter screen 130 provided by the embodiments of the present application includes a housing 100, the housing 100 is enclosed by a top wall 101, a bottom wall 102 opposite to the top wall 101, and a side wall 103 extending between the top wall 101 and the bottom wall 102; an air inlet 110 and an air outlet 120 are respectively formed in the side wall 103 and the top wall 101 of the housing 100, a filter screen 130 is mounted at the air outlet 120 and used for isolating or adsorbing garbage, dust and the like, and the filter screen 130 is horizontally placed or obliquely placed to cover the air outlet 120; in the housing 100, a baffle 140 is disposed on an airflow path between the inlet 110 and the outlet 120, the baffle 140 is opposite to the inlet 110, and wind entering the housing 100 from the inlet 110 impacts the baffle 140 and is discharged from the outlet 120. When the sweeper works, the fan sucks garbage, dust and the like into the shell 100 along with air through the air inlet 110, and airflow carrying the garbage and the dust firstly collides with the baffle 140 and then is thrown to the filter screen 130.
Referring to fig. 6, a schematic structural diagram of the dust collecting box provided by the present application when the dust collecting box is used in sweeping is shown, and arrows indicate the flow direction of air flow in the sweeper. After the airflow collides with the baffle 140, most of the carried garbage and dust, especially larger particles of objects, are blocked by the baffle 140 due to the larger inertia and fall to the bottom of the housing 100, a small amount of dust is thrown to the filter screen 130 after changing the direction along with the airflow, and after being filtered by the filter screen 130, the clean airflow is discharged from the air outlet 120. So set up, compare with the traditional dust collection box that the filter screen just faces the air intake, the motion trail of air current changes, and before throwing to filter screen 130, can throw to baffle 140 earlier, reduces on the one hand rubbish and dust and is thrown to filter screen 130 directly, makes the probability that filter screen 130 blockked up, and on the other hand has reduced the quantity of rubbish and dust that reach filter screen 130, has prolonged the live time of filter screen 130, need not frequent change or clean filter screen 130.
In the embodiments of the present application, the filter screen 130 is disposed on the top wall 101 of the housing 100, when the blower is not in operation, the airflow flowing through the dust collecting box disappears, and the garbage on the filter screen 130 falls down due to gravity, so as to achieve the effect of self-cleaning the filter screen 130. Moreover, the garbage is accumulated at the bottom of the dust collecting box after falling down, and the filter screen 130 is not blocked. Compare the structure that filter screen 130 set up at the dust collection box lateral wall 103, this application can prevent that the rubbish that gathers in the dust collection box from blockking up the lower half of filter screen 130. Referring to fig. 1, in the conventional dust box, a filter net is installed on a sidewall of the dust box, and even though dust falls down by gravity without a suction action of a blower, the dust is still accumulated on the filter net blocking the middle and lower portions faster than the upper filter net.
The baffle 140 is installed at an angle and has a length and a width such that the garbage thrown from the inlet 110 cannot directly hit the screen 130. Generally, the included angle between the baffle 140 and the axial direction of the air inlet 110 is set to 60 ° to 120 °, so that the air flow is firstly thrown onto the baffle 140 after entering, and the length and the width are suitable for the baffle 140 to completely block the air flow section after being opened. When the plane of the intake vent 110 is a regular plane, the orientation of the baffle 140 can be visually depicted as the angle between the plane of the intake vent 110. The included angle is sized such that all or most of the air flow is thrown against the baffle 140 when entering.
It is understood that the baffle 140 may be located anywhere between the inlet 110 and the outlet 120, or that the outlet 120 is located downstream in the direction of airflow relative to the baffle 140. In a preferred embodiment, the baffle 140 is disposed at the dust box inlet 110.
In some embodiments, the surface of the baffle 140 facing the airflow may be a flat surface or an arc surface to facilitate wind guiding.
In some embodiments, the baffle 140 is fixedly disposed within the housing 100. However, in order to exert the maximum function of the baffle 140, in a preferred embodiment, the baffle 140 is rotatably mounted in the housing 100 around a rotating shaft 150, referring to fig. 3, when the sweeper is not in operation, the baffle 140 covers the air inlet 110, so that the garbage is prevented from reversely leaking; when the sweeper works, the baffle 140 rotates by a certain angle under the action of the airflow to open the air inlet 110 to block the airflow, and the maximum opening angle of the baffle 140 is restricted by the limiting structure, so that all or most of the airflow is thrown onto the baffle 140 when entering. In some existing dust collecting boxes, although a turnover blocking piece is additionally arranged at an air inlet and used for blocking the air inlet in the absence of wind, the turnover angle of the blocking piece is not restricted, so that the blocking piece is fully opened when air flow enters, the air flow is still directly blown onto a filter screen, and the service life of the filter screen is not improved.
Specifically, in each embodiment of the present application, the limiting structure includes a protruding rib 151 disposed on the rotation path of the baffle 140, and an interference portion 152 corresponding to the protruding rib 151, optionally, any one of the interference portion 152 and the protruding rib 151 is disposed on the baffle 140, the other one is disposed on the housing 100, when the baffle 140 rotates to the maximum opening angle, the protruding rib 151 abuts against the interference portion 152, so as to prevent the baffle 140 from further rotating, and form a constraint on the opening angle of the baffle 140.
Referring to fig. 4 and 5, in a preferred embodiment, the protruding rib 151 may be disposed on the surface of the rotating shaft 150, and the interference portion 152 may be disposed on the inner wall of the housing 100. Of course, the limiting structure has various modes, and besides the described structure, the limiting structure can be arranged at other parts of the dust collection box as long as the limiting function can be realized on the opening angle of the baffle plate 140.
Further, the opening direction of the baffle 140 may be opened above the intake vent 110 or obliquely above, or may be opened to the left side or the right side of the intake vent 110. When the rotating shaft 150 is disposed above or obliquely above the air inlet 110, the baffle 140 is opened above or obliquely above the air inlet 110, and in a windless state, the baffle 140 can rotate by its own weight to cover the air inlet 110, so that the structure is simple and practical. Referring to fig. 4, especially, the air inlet 110 may be disposed obliquely, so that the upper side of the air inlet 110 is far away from the center of the housing 100 than the lower side of the air inlet 110, when the baffle 140 covers the air inlet 110, the gravity of the baffle 140 has a component force in a direction perpendicular to a contact surface between the baffle 140 and the air inlet 110, so that the baffle 140 is tightly attached to the air inlet 110 and is not easily opened by shaking.
When the baffle 140 is opened to the left or right, an external force is required to make the baffle 140 cover the air inlet 110 in a windless state, specifically, the rotating shaft 150 is sleeved with the torsion spring 160, one end of the torsion spring 160 is fixed or abutted against the inner wall of the housing 100, and the other end is fixed or abutted against the baffle 140. When the sweeper does not work, the baffle 140 covers the air inlet 110 under the elastic force of the torsion spring 160, and when the sweeper works, the airflow overcomes the elastic force of the torsion spring 160 to push the baffle 140 open.
Further, referring to fig. 4 again, when the baffle 140 is turned upwards, the opening angle of the baffle 140 can be depicted as an included angle with the horizontal direction, when the baffle 140 is turned to the maximum opening angle, the included angle is preferably-45 ° to 45 °, especially 15 ° to 45 °, so as to better block the airflow, the airflow turning angle is suitable, and after the airflow enters, the airflow turns to the downward inclined direction through the baffle 140, and then continues to move upwards to the filter screen 130, so that the influence of the airflow on the falling process of the garbage and the dust is reduced, and the garbage and the dust are favorably deposited to the bottom of the dust collecting box.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
