The present disclosure relates to a rod-type cleaning component and a dust collector with the same, and belongs to the field of manufacturing of small household appliances technology.
At present, cross-sectional areas of water suction pipes of most of cleaning products on the market are roughly round or roughly rectangular. In an operating process, sewage flows up along a sidewall of the water suction pipe, and meanwhile, the air also goes up in the water suction pipe. For ensuring an air inlet area of a motor of a main unit, a certain dimensional requirement is made on a cross-sectional area of a water inlet pipe, which makes it impossible to further increase a flow velocity of the air in the water suction pipe due to the limits of the cross-sectional area. As a result, when the sewage flows up to a certain height, a thrust provided by the airflow in the water suction pipe may not offset the gravity of the sewage, and the sewage may not be effectively delivered to a recycling tank. In addition, when the water suction pipe works, the flow velocity of the airflow on two sides of the water suction pipe is low because of high resistance generated by delivery of the sewage, while the airflow in the center of the water suction pipe moves upwards at a high flow velocity without any resistance, so that it is very likely to cause turbulence in the pipe in case of a high liquid flow to affect the effect that the sewage climbs up along the wall.
For solving the foregoing problem, the climbing effect of the sewage of most of products on the market may be ensured only by use of methods of reducing a climbing height of the sewage, etc. which not only greatly affects the layout of the products but also does not solve the problem radically.
For solving the shortcomings of the conventional art, the present disclosure provides a rod-type cleaning component and a dust collector with the same. A suction pipe is divided into multiple air ducts by separation ribs to not only enlarge a climbing area of water along a wall but also ensure that a flow velocity of the air in each chamber in multiple separated chambers in the air ducts is uniform and avoid interference between the chambers, so that the water suction efficiency of the cleaning component and the dust collector is greatly improved, and in addition, the products are more attractive in appearance and simpler.
The technical problem to be solved in the present disclosure is solved through the following technical solutions.
A rod-type cleaning component includes a rod body, the rod body includes a suction pipe connected with a suction inlet of a floor brush, a recycling tank for recycling sewage and a solution tank for providing clean liquid, a main unit joint is arranged at an upper end of the rod body, a floor brush joint is arranged at a lower end, and more than one separation ribs are arranged in an inner cavity of the suction pipe to divide the inner cavity into more than two chamber air ducts. Specifically, cross-sectional areas of the chamber air ducts are substantially the same.
For ensuring sufficient product strength and avoiding the influence of impact of airflow and a water flow, the separation ribs are preferably made from a rigid material.
More specifically, the rod body further includes a separation chamber formed above and communicated with the recycling tank, and an air-water separation device is arranged in the separation chamber; and according to a flowing direction of an air-solid-liquid mixture, an upstream of the separation chamber is connected with a water outlet of the suction pipe, and a downstream is connected with the main unit joint.
The present disclosure also provides a dust collector, which mainly includes a main body and a floor brush connected therewith. The main body includes a body and a dust cup connected with the body, a dust collection pipe is arranged on the dust cup, a vacuum source for generating a suction force and a battery supplying power to the vacuum source are arranged in the body, and a handle is arranged on one side of the body. The handheld dust collector further includes the aforementioned rod-type cleaning component, the main unit joint is connected with the dust collection pipe, and the floor brush joint is connected with the floor brush.
Specifically, an axis of the battery is parallel to an axis of the handle.
Based on the above, the present disclosure provides the rod-type cleaning component and the dust collector with the same. The suction pipe is divided into multiple air ducts by the separation ribs to not only enlarge a climbing area of water along a wall but also ensure that a flow velocity of the air in each chamber in multiple separated chambers in the air ducts is uniform and avoid interference between the chambers, so that the water suction efficiency of the cleaning component and the dust collector is greatly improved, and in addition, the products are more attractive in appearance and simpler.
The technical solutions of the present disclosure will be described below in combination with the drawings and specific embodiments in detail.
In combination with
When the rod-type cleaning component and the dust collector works, clean water or cleaning solution in the solution tank 130 enters the floor brush 2000 from a water outlet valve 131 through a water outlet pipe 132, and a floor is cleaned through the floor brush. Meanwhile, sewage enters the suction pipe 110 with multiple air ducts from the floor brush through the floor brush joint 300. With formation of multiple air duct chambers in the suction pipe 110, air in each air duct flows at a uniform high velocity. The sewage is driven by the air flowing at the high velocity to climb up rapidly through a sidewall of the suction pipe 110 and a sidewall of the separation rib 1101. In such case, with formation of the multiple air ducts, a chamber with sewage and a chamber without sewage may not be affected by each other due to different flow velocities of the air. Then, the sewage and the air enter the air-water separation device 400 from the water outlet through the suction pipe with the multiple air ducts, and after passing through the air-water separation device 400, clean air enters a main unit of the dust collector through the main unit joint 200, and the sewage enters the recycling tank 120 from the inlet under the influence of centrifugation and the gravity. In such a manner, a cleaning operating process of the rod-type cleaning component and the dust collector is completed.
Based on the above, the present disclosure provides the rod-type cleaning component and the dust collector with the same. The basic principle that water flows along a wall is fully utilized, and the suction pipe is divided into multiple air ducts by the separation ribs to not only enlarge a climbing area of water along a wall but also ensure that a flow velocity of the air in each chamber in multiple separated chambers in the air ducts is uniform and avoid interference between the chambers, so that the water suction efficiency of the cleaning component and the dust collector is greatly improved, and the efficiency of the products is fully utilized. In addition, since a climbing height of the sewage is effectively improved, the influence thereof on the planning and layout of the products is avoided, and provision of more attractive, simple and high-performance cleaning products for consumers is facilitated.
