[0031] Figure 2 This is a three-dimensional combined schematic diagram of the cleaning equipment embodiment two of this application;

[0032] Figure 3 This is a perspective view of the separate impeller in the cleaning equipment of this application. Detailed Implementation

[0033] Please refer to Figure 1 and Figure 2 This application relates to a cleaning device for cleaning surfaces to be cleaned. The cleaning device includes: a clean water tank (not shown), a clean water pipe (not shown), a cleaning head 1, a sewage pipe 2, a sewage tank 3, a gas-liquid separation assembly 4, a main motor 5 (not fully shown), and a controller (not shown).

[0034] The cleaning head 1 is used to move across the surface to be cleaned and absorb dirt from the surface. The clean water tank is connected to the cleaning head 1 via a clean water pipe and is used to distribute the cleaning solution onto the surface to be cleaned through the cleaning head 1; the wastewater tank 3 is connected to the cleaning head 1 via a wastewater pipe 2 and is used to collect dirt from the surface to be cleaned into the wastewater tank 3.

[0035] Specifically, a water pump (not shown) can be installed on the clean water pipe to control the supply of clean water to the clean water tank; a roller brush motor (not shown) is installed on the cleaning head 1 to control the rolling of the roller brush 12.

[0036] The gas-liquid separation component 4 is located at the outlet of the sewage tank 3. The gas-liquid separation component 4 includes an impeller motor 41 and a separation impeller 42 located on the output shaft of the impeller motor 41.

[0037] The main motor 5 is connected to the outlet of the sewage tank 3, and is used to form a recycling path that passes through the cleaning head 1, sewage pipe 2, sewage tank 3 and gas-liquid separation component 4 in sequence in the first working mode.

[0038] The controller is electrically connected to the main motor 5 and the impeller motor 41. In the second operating mode, the main motor 5 stops working in response to the controller's control signal, and the impeller motor 41 drives the separation impeller 42 to rotate in response to the controller's control signal, thereby forming an airflow in the recovery path to dry at least one of the cleaning head 1, sewage pipe 2, sewage tank 3, and gas-liquid separation assembly 4.

[0039] Please refer to Figure 1 and Figure 2 As shown, in Embodiments 1 and 2 of this application, the heating element 6 is electrically connected to the controller. The heating element 6 generates heat in response to the control signal of the controller to heat the airflow passing through the recovery path.

[0040] exist Figure 1 In the first embodiment of this application shown, the heating element 6 is located upstream of the separating impeller 42; specifically, the heating element 6 is located in a ring shape between the impeller motor 41 and the separating impeller 42. In the second operating mode, the impeller motor 41 drives the separating impeller 42 to rotate in a first direction in response to the control signal of the controller, so as to generate a force opposite to that of the main motor 5 in the recovery path.

[0041] exist Figure 2 The second embodiment of this application shown also includes a charging base 7. The charging base 7 has a receiving cavity 70 that can dock with the cleaning head 1, and a heating element 6 is disposed on the charging base 7 and located to the side of the receiving cavity 70. In the second operating mode, the impeller motor 41 drives the separating impeller 42 to rotate in a second direction in response to the control signal of the controller, so as to generate the same force as the main motor 5 in the recycling path.

[0042] Specifically, the charging base 7 has an external AC power adapter. In the second operating mode, the impeller motor 41 is driven by the power adapter. This is because the inventors discovered during their long-term research that a typical battery pack cannot discharge at high power during charging due to the small current drawn by the power adapter, while the main motor 5 experiences its maximum load during normal operation. Since the load on the impeller motor 41 is less than that of the main motor 5, in the second operating mode, the battery pack is not required to power the impeller motor 41 as long as the main motor 5 is not operating. During this process, the power to the impeller motor 41 can be provided by the power adapter.

[0043] Of course, it should also be noted that the cleaning head 1 includes a roller brush 12 and a roller brush motor connected to the roller brush 12, and the roller brush motor is electrically connected to the controller. In the second working mode, the roller brush motor responds to the control signal of the controller and alternately drives the roller brush 12 to rotate forward for a preset duration, and then drives the roller brush 12 to rotate in the reverse direction for a preset duration. The purpose of this setting is to improve the drying effect of the roller brush 12 by rotating it in both directions; and to avoid the roller brush bristles being dried and flattened by the bottom wall of the receiving cavity 70 or the water-spreading scraper and other components in the cleaning head 1 when the roller brush 12 rotates in one direction, which would affect the subsequent cleaning effect.

[0044] This application also relates to a control method for the aforementioned cleaning equipment, the control method comprising:

[0045] In the second operating mode, after the main motor 5 stops working, the impeller motor 41 drives the separator impeller 42 to rotate, thereby forming an airflow in the recovery path to dry at least one of the cleaning head 1, sewage pipe 2, sewage tank 3, and gas-liquid separation assembly 4. The heating element 6 generates heat to heat the airflow passing through the recovery path.

[0046] Corresponding to Embodiment 1 of the cleaning equipment, the step of the impeller motor 41 driving the separating impeller 42 to rotate includes: the impeller motor 41 driving the separating impeller 42 to rotate in a first direction to generate a force opposite to that of the main motor 5 in the recycling path. The heating element 6 generates heat to heat the airflow passing through the recycling path, i.e., the hot airflow sequentially passes through the sewage tank 3, the sewage pipe 2, and the roller brush 12 in the cleaning head 1, and is then discharged outside the entire machine, thus thermally drying the inner walls of these parts.

[0047] Corresponding to Embodiment 2 of the cleaning equipment, the step of the impeller motor 41 driving the separating impeller 42 to rotate includes: in the second working mode, the impeller motor 41 drives the separating impeller 42 to rotate in a second direction to generate the same force as the main motor 5 in the recycling path. The heating element 6 generates heat to heat the airflow passing through the recycling path, i.e., the hot airflow sequentially passes through the roller brush 12, sewage pipe 2, and sewage tank 3 in the cleaning head 1, and then is discharged outside the whole machine, thus thermally drying the inner walls of these parts.

[0048] The cleaning mode of clean water tank -> clean water pipe -> cleaning head 1 -> sewage pipe 2 -> sewage tank 3 is the first working mode. The first working mode includes the normal cleaning process, that is, the clean water tank supplies water, the cleaning head cleans the ground, the main motor sucks up the sewage, and it is collected into the sewage tank, where the gas-liquid separation component 4 performs separation. The first working mode can also include a self-cleaning process. In the self-cleaning process, the clean water tank also needs to supply water, the roller brush 12 in cleaning head 1 rotates, and the main motor 5 sucks up water. The main motor 5 can have a delay during startup to allow the roller brush to be fully cleaned before collection. After self-cleaning, the second working mode, the drying mode, begins. In this drying mode, the main motor 5 must not operate, but the impeller motor 41 needs to operate; other components can be inactive.

[0049] In summary, in Embodiment 1 of this application, when the impeller motor 41 drives the separating impeller 42 to rotate in the first direction, the airflow blows downward; in Embodiment 2 of this application, when the impeller motor 41 drives the separating impeller 42 to rotate in the second direction, the airflow blows upward; in another Embodiment 3 not shown, the impeller motor 41 can drive the separating impeller 42 to rotate alternately in the forward and reverse directions, so the airflow can alternately blow downward and upward. Correspondingly, heating elements 6 can be provided on both the charging base 7 used as a base station and the gas-liquid separation assembly 4.

[0050] It is particularly important to note that in the second operating mode, the impeller motor 41 can either continuously drive the separator impeller 42 or intermittently drive it. Please refer to [reference needed]. Figure 3 The separating impeller 42 has an inner wall surface and an outer wall surface arranged opposite to each other. The separating impeller 42 includes several blades 421 twisted on the outer wall surface and several gap holes 420 between adjacent blades 421. The separating impeller 42 rotates under the drive of the impeller motor 41, and has different functions in different modes: Specifically, in the first mode, after the gas-liquid two-phase mixture drawn by the main motor 5 to the outlet of the sewage pipe 2 reaches the separating impeller 42, the separating impeller 42 generates high-speed centrifugal force through rotation, which throws the droplets attached to the surface of the separating impeller 42 out and then falls into the bottom of the sewage tank 3. Air enters and exits the separating impeller 42 through the gap holes 420, thereby realizing gas-liquid separation; while in the second working mode, the rotation of the separating impeller 42 mainly utilizes the torsional force generated between the blades 421, which can drive the airflow in the recovery path. Therefore, the rotation speed of the impeller motor 41 in the second working mode is usually lower than that in the first mode; however, the rotation speed of the impeller motor 41 in the second working mode is also adjustable, that is, it has multiple speed settings.

[0051] This application uses an impeller motor 41 to drive a separating impeller 42 to rotate in response to a control signal from a controller, thereby creating an airflow in the recovery path to dry at least one of the cleaning head 1, sewage pipe 2, sewage tank 3, and gas-liquid separation assembly 4. In a preferred embodiment, this application also includes a heating element 6 electrically connected to the controller. The heating element 6 generates a hot airflow in response to a control signal from the controller to heat the airflow passing through the recovery path, thereby accelerating the drying of the cleaning head 1, sewage pipe 2, sewage tank 3, and gas-liquid separation assembly 4.
