The present disclosure relates to the technical field of cleaning devices, and in particular to a cleaning system achieving a plurality of cleaning paths by using a single vacuum source.
Many devices in a vacuum cleaning apparatus (including a dust collector, a floor scrubber, etc.) on the market have vacuum nozzles. Dirt is collected by an airflow and a brush for stain removal. The dirt is transported to a dirt container, while the remaining airflow leaves the devices through a vacuum source. However, the current single airflow channel can collect dirt into the dirt container, but cannot transfer the dirt from the dirt container, and thus manual contact with the dirt container is mostly required during cleaning. Taking a dust collector as an example, after the dust collector sucks the dirt into a dust cup, a user needs to remove the dust cup and pours the dirt inside into a trash can.
Currently, in order to solve the problem of manually removing the dirt container for cleaning, a dust collector base station has appeared on the market, such as a dust collector base station, a dust collector system, and a control method of the dust collector base station provided in the patent application 202180018767.5. A stick dust collector with a dust collection cylinder is integrated within the base station, a dust collection motor is disposed in the base station, a suction motor (located in the dust collector) is used as a vacuum source to suck the dirt into the dust collector, and the dust collection motor (located in the base station) is used as the vacuum source to transfer the dirt in the dust collector to the base station. A dust suction system and a dust exhaust system are controlled by different vacuum sources, respectively. However, the current base stations on the market all have independent vacuum sources as mentioned above to achieve the normal operation of the dust exhausting air path.
However, the applicant believes that this kind of structure requires two vacuum sources to be installed in the overall system. By controlling different vacuum sources to work, the switching of the cleaning system is achieved, enabling the cleaning system to have a relatively high production cost. Therefore, it is necessary to provide a cleaning device achieving dual/a plurality of air paths switching with only one vacuum source. Furthermore, the current dust collector has a relatively single function and cannot use the same vacuum source to achieve multi-purpose of one machine, while this device can form a variety of cleaning systems to meet the cleaning requirements of users.
In order to overcome the shortcomings in the existing technology, the object of the present disclosure is to provide a cleaning system achieving a plurality of cleaning paths by using a single vacuum source, so as to solve the problems mentioned in the above background art.
In order to achieve the above object, the present disclosure adopts the following technical scheme:
Further, the air inlet of the first air path is a dirt inlet, and the air outlet is disposed on the housing corresponding to the vacuum source.
Further, the switching module includes a three-way pipeline, which is separately docked with the vacuum source and the dust storage cavity and constitutes the second air path; and an air path switching device is disposed in the three-way pipeline, and used for controlling the opening and closing of the first air path and the second air path.
Further, the air path switching device includes a valve switch, the valve switch includes a baffle and a rotating point, the rotating point is located at one end of the baffle and rotatably disposed in the three-way pipeline, and the baffle can rotate around the rotating point.
As another scheme, the cleaning system further includes a dirt collection assembly, the dirt collection assembly is used for docking with the dust collector body to form the second air path; the dirt collection assembly is provided with a dirt recovery bin and an external air duct for communicating with the switching module, and the external air duct is used for forming the second air path.
Further, when the dirt collection assembly is docked with the dust storage cavity of the dust collector body, a path of the second air path is: the air inlet-the dust storage cavity-the dirt recovery bin-the external air duct-the switching module-the vacuum source-the air outlet.
Further, the air inlet in the second air path is the dirt inlet, and the air outlet is disposed on the housing corresponding to the vacuum source.
Further, a first filtering device is disposed at an air path interface between the dust storage cavity and the switching module, the air inlet of the second air path is provided on the housing between the dust storage cavity and the switching module, and the path of the second air path is: the air inlet-the first filtering device-the dust storage cavity-the dirt recovery bin-the external air duct-the switching module-the vacuum source-the air outlet.
Further, when the dirt collection assembly is not docked with the dust storage cavity of the dust collector body, the path of the second air path is: the air inlet-the dirt recovery bin-the external air duct-the switching module-the vacuum source-the air outlet; and the air inlet is disposed on the dirt collection assembly.
Further, one end of the external air duct communicates with the dirt recovery bin while the other end of the external air duct communicates with the switching module, a second filtering device is disposed at the interface between the external air duct and the dirt recovery bin, and used for preventing the dirt in the dirt recovery bin from entering the external air duct.
Compared with the existing technology, the beneficial effects of the present disclosure are as follows:
The cleaning system forms different cleaning paths by the vacuum source of the dust collector body and using the docking between the airflow switching module and the dirt collection assembly. The airflow switching module can switch the airflow path according to cleaning needs, achieving the docking between the vacuum source and different dirt collection systems (such as the dust collection station of the dust collector, the sewage tank of the floor scrubber, etc.) to form different working air paths.
When the dirt collection assembly is docked with the dust storage cavity of the dust collector body, the dirt collection assembly is used for recovering dirt in the dust collector body, and the dirt collection assembly does not require an independent vacuum source, and thus it can be the dust collection station of the dust collector. The valve switch in the airflow switching module is switched to achieve the air path docking between the vacuum source of the dust collector body and the dirt collection container. The vacuum source of the dust collector body is used for transferring the dirt collected in the dust storage cavity to the dirt recovery bin of the dirt collection assembly. The dirt collection assembly does not require the independent vacuum source, effectively achieving non-contact dust dumping, improving user experience and reducing product manufacturing costs.
When the dirt collection assembly is not docked with the dust storage cavity of the dust collector body, the dirt collection assembly is used for cleaning dirt in an external environment, and thus it can be the sewage tank of the floor scrubber. The dirt collection container is docked with the vacuum source of the dust collector body, and the airflow switching module is used for achieving the second air path. Moreover, the air inlet of the second air path is disposed on the dirt collection assembly, and may be the dirt inlet of the dirt collection assembly, such that dual-use of one machine is achieved, thereby meeting more cleaning needs of users.

The air path switching device includes a valve switch, the valve switch includes a baffle 10 and a rotating point 11, the rotating point 11 is located at one end of the baffle 10 and rotatably disposed in the three-way pipeline, and the baffle 10 rotates around the rotating point 11 to block the first air path and communicate with the second air path or block the second air path and communicate with the first air path.
Two interfaces of the three-way pipeline can be blocked respectively by rotating the baffle 10 disposed in the three-way pipeline to different positions. These two interfaces are an interface between the switching module 5 and the second air path and an interface between the switching module 5 and the dust storage cavity, respectively. Of course, other types of mechanical/electronic control switches can also be used, and the control method of air path opening and closing can be changed according to actual conditions.
