Example one
The present embodiment provides an exhaust manifold of a cleaning device, referring to fig. 1 to 5, comprising at least one set of pipe assemblies, wherein the pipe assemblies comprise an outlet pipe 1 and at least two inlet pipes 2 connected with the air inlets of the outlet pipe 1, and the air outlets of the outlet pipe 1 are oriented differently from the air inlets of the inlet pipes 2.
When the device is implemented, gas discharged from the gas outlet of the cone part sequentially passes through the inlet pipe 2 and the outlet pipe 1 and then enters a fluid channel formed by the enclosure 4 and the motor cover 6.
Compared with the prior art, in the exhaust manifold of the cleaning device provided by the embodiment, one outlet pipe 1 corresponds to at least two inlet pipes 2, so that the number of the outlet pipes 1 can be greatly reduced, the structures of the exhaust manifold and the fluid air channel are simplified, and the volume of the cleaning device is further reduced.

In order to facilitate the introduction of the fluid from the inlet pipe 2 into the outlet pipe 1, the diameter of the air inlet of the flow converging region 3 is larger than the diameter of the air outlet of the flow converging region 3, so that the air flows flowing out of the plurality of inlet pipes 2 can smoothly enter the flow converging region 3 and gradually converge into one fluid under the converging action of the flow converging region 3, thereby facilitating the fluid to enter the flow converging region 3.
Illustratively, from the perspective of fluid flow stability, from the inlet pipe 2 to the outlet pipe 1 direction, the confluence region 3 includes a leading-in section, a flow stabilizing section and a leading-out section which are arranged in sequence, wherein the diameter of a gas inlet of the leading-in section is larger than the diameter of a gas outlet of the leading-in section, the diameter of the flow stabilizing section is kept unchanged, the diameter of a gas inlet of the flow stabilizing section is equal to the diameter of a gas outlet of the flow stabilizing section, the diameter of a gas inlet of the leading-out section is smaller than the diameter of a gas outlet of the leading-out section, and the diameter of a gas inlet of the leading-in section is larger than the diameter of a gas outlet of the leading-out section.

In addition, for the arrangement of the fluid passage 8, the cleaning device of the embodiment can omit the arrangement of the fluid passage 8 by reserving a certain gap between the housing 4 and the motor cover 6 and using the space in the gap as the fluid passage 8, thereby not only reducing the usage amount of raw materials, but also effectively simplifying the overall structure of the cleaning device.
As for the structure of the cone portion 5, specifically, it includes a plurality of cones arranged along the circumference of the cleaning device and a cover body buckled on the air outlet of the cone, the inlet pipe 2 is communicated with the interior of the cone through the cover body.

Thus, partial surfaces of the conical part 5, the air guide sleeve 9 and the exhaust manifold are used as the shell 4, the area of the shell 4 which is arranged independently can be reduced, raw materials are effectively utilized, and the whole structure of the cleaning equipment is simplified.
In order to reduce the whole volume of the cleaning device, the outer wall surface of the motor cover 6 is provided with a groove for accommodating part or all of the outlet pipe 1, and part or all of the outlet pipe 1 is arranged in the groove. In this way, by providing the recess, it is possible to accommodate part or all of the outlet pipe 1 with the space of the motor cover 6, and thus it is possible to reduce the diameter and the overall volume of the rear end portion of the cleaning device.

In addition, the flocculent dirt can enter the dust collecting area of the dust collecting cup after falling off from the filter screen cover 10 under the action of the reverse fluid, and the flocculent dirt is convenient to collect.
