Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a partition structure applied to a sewage tank. Background Art

[0002] To solve the problem that sewage is likely to backflow into the vacuum motor when the body of a handheld cleaning device is used in a tilted state, the applicant proposes to use a partition to divide the sewage tank into a first cavity and a second cavity (a through hole communicating the first cavity and the second cavity is provided on the partition). An inlet for sewage, a first air extraction port, and a second air extraction port are provided on the sewage tank. The inlet for sewage extends inward to form a sewage inlet pipe communicating with the first cavity. The first air extraction port communicates with the first cavity and is used to connect to the suction end of the vacuum motor. The second air extraction port communicates with the second cavity and is used to connect to the suction end of the vacuum pump. During use, the air in the first cavity is sucked by the vacuum motor so that sewage enters the first cavity through the sewage inlet pipe, and the air in the second cavity is sucked by the vacuum pump so that sewage enters the second cavity from the first cavity through the through hole. That is, the vacuum motor is separated from the sewage storage area, thereby avoiding the problem of sewage backflowing into the vacuum motor.

[0003] However, it is found in the actual use process that, in the tilted state, the sewage sucked into the second cavity will flow back to the first cavity through the through hole under the action of surging; the problem of sewage backflowing into the vacuum motor in the tilted use state is still not completely solved.

[0004] Therefore, in view of the deficiencies of the existing technology, it is necessary to design a partition structure applied to a sewage tank to solve the above problems. Summary of the Utility Model

[0005] To overcome the above deficiencies in the existing technology, the purpose of the utility model is to provide a partition structure applied to a sewage tank.

[0006] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a partition structure applied to a sewage tank, an inlet for liquid is provided on the top side of the partition, an outlet for liquid is provided on the bottom side of the partition, the diameter of the inlet for liquid is larger than the diameter of the outlet for liquid, and a bent pipeline communicating the inlet for liquid and the outlet for liquid is formed in the partition.

[0007] The preferred technical solution is: the bent pipeline adopts an S-shaped pipeline or a C-shaped pipeline or a Z-shaped pipeline.

[0008] The preferred technical solution is: the inlet for liquid is arranged close to the user side.

[0009] The preferred technical solution is: the outlet for liquid is arranged far from the user side.

[0010] The preferred technical solution is that the caliber of the liquid inlet is larger than that of the liquid outlet.

[0011] The preferred technical solution is that a detachable filter disc is further provided on the top side of the partition board, and a plurality of filter holes are provided on the bottom of the filter disc.

[0012] Due to the application of the above technical solution, the beneficial effects of the present utility model are as follows:

[0013] The partition board structure applied to the sewage tank provided by the present utility model prolongs the liquid flow path and slows down the liquid flow rate by arranging a liquid inlet on the top side of the partition board, a liquid outlet on the bottom side of the partition board, and a bent pipeline connecting the liquid inlet and the liquid outlet in the partition board, so as to avoid the direct passage of liquid; in the actual use process of this structure, it can effectively prevent sewage from entering the top side cavity from the bottom side cavity due to surges, and thus effectively solve the problem of sewage backflow into the vacuum motor. Its structure is simple and ingenious in design, and is suitable for popularization. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Embodiment:

[0020] As Figures 1 to 2 shown, according to a general technical concept of the present utility model, there is provided a partition structure applied to a sewage tank. An inlet is provided on the top side of the partition 1, and an outlet is provided on the bottom side of the partition 1. The diameter of the inlet is larger than that of the outlet. A bent pipeline 11 communicating the inlet and the outlet is formed in the partition 1.

[0021] As Figures 1 to 2 shown, in an exemplary embodiment of the present utility model, the bent pipeline 11 adopts an S-shaped pipeline, a C-shaped pipeline, or a Z-shaped pipeline to extend the liquid flow path and slow down the liquid passing speed.

[0022] As Figures 1 to 2 shown, in an exemplary embodiment of the present utility model, the inlet is arranged near the user side, that is, to ensure that when the sewage tank is in a dumping state (the sewage tank is dumped towards the user side), the inlet is at a lower position, facilitating the discharge of sewage from the inlet.

[0023] As Figures 1 to 2 shown, in an exemplary embodiment of the present utility model, the outlet is arranged away from the user side, that is, to ensure that when the sewage tank is in a dumping state (the sewage tank is dumped towards the user side), the outlet is at a higher position, so that it is difficult for sewage to flow out from the outlet.

[0024] As Figures 1 to 2 shown, in an exemplary embodiment of the present utility model, the diameter of the inlet is larger than that of the outlet, further avoiding the situation of sewage diversion.

[0025] As Figures 1 to 2 shown, in an exemplary embodiment of the present utility model, a detachable filter plate 3 is further provided on the top side of the partition. A plurality of filter holes are provided on the bottom of the filter plate 3 for filtering solid-liquid garbage to prevent solid garbage from blocking the bent pipeline 11.

[0026] In addition, a sewage inlet is usually provided on the bottom side of the sewage tank, and the sewage inlet extends inward to form a vertically arranged sewage pipe. A through hole 12 for the sewage pipe to pass through is provided at the center of the partition 1 in this application, and a sealing ring for sealing connection with the outer wall of the sewage pipe is provided on the inner ring of the through hole 12. In addition, a liquid level sensor 2 for monitoring the sewage volume is also provided on the bottom side of the partition 1, which can prevent sewage from overflowing.

[0027] Therefore, the utility model has the following advantages:

[0028] The partition structure applied to the sewage tank provided by the utility model prolongs the liquid flow path and slows down the liquid flow rate by setting a liquid inlet on the top side of the partition, a liquid outlet on the bottom side of the partition, and a bent pipeline connecting the liquid inlet and the liquid outlet in the partition, so as to prevent the liquid from passing directly through. During actual use, this structure can effectively prevent sewage from entering the top side cavity from the bottom side cavity due to surges, and thus effectively solve the problem of sewage backflow into the vacuum motor. Its structure is simple and ingenious, and is suitable for popularization.

[0029] The above embodiments merely illustrate the principles and effects of the utility model, rather than limiting the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the utility model should still be covered by the claims of the utility model.
