[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figure 1-3As shown, the present invention proposes an automatic water inlet and outlet mechanism for a sweeping robot. The water inlet mechanism includes a water inlet pipe 11, which inlets water through a water inlet end seat 12. A pressure reducing valve 13 and a negative pressure valve 14 are sequentially arranged on the water inlet pipe 11 along the liquid transmission direction.

[0026] The liquid supply mechanism includes a water inlet tee 21 connected to the water inlet pipe 11. The remaining two ends of the water inlet tee 21 are connected to the cleaning agent pipe 22 and the liquid supply end seat 24, respectively. The cleaning agent pipe 22 is equipped with a flow rate regulating switch 23.

[0027] The sewage system includes a sewage bottle 31, a sewage pipe 32 is installed at one end of the sewage bottle 31, a sewage end seat 33 is provided on the sewage pipe 32 to connect to the robot's drainage part, a sewage pipe 35 is installed at the lower part of the sewage bottle 31, and a one-way valve 34 for one-way transmission is provided on the sewage pipe 35.

[0028] The ventilation mechanism includes a gas supply tee 42 located on one side of the sewage bottle 31. The gas supply tee 42 is connected to the sewage bottle 31 via a ventilation pipe 41, and the remaining two ends are connected to a vacuum pipe 43 and a suction pipe 44, respectively. A ventilation regulating switch 45 for adjusting the flow rate is installed on the ventilation pipe 41.

[0029] It should be noted that: the water inlet pipe 11 is connected to the external water supply equipment through the water inlet end seat 12, and tap water is drawn in through the water inlet end seat 12. The pressure reducing valve 13 is used to reduce pressure during the water intake process, and the negative pressure valve 14 is used to adjust the channel of the water inlet pipe 11 to a negative pressure state for the intake of tap water.

[0030] In this embodiment, the water inlet mechanism and the liquid supply mechanism work together to supply water to the sweeping robot. First, the water inlet mechanism supplies tap water for cleaning to the sweeping robot. When the water inlet pipe 11 stops supplying water, the channel of the water inlet tee 21 is switched, and the cleaning agent pipe 22 and the liquid supply end seat 24 are connected to form a cleaning agent channel to deliver the cleaning agent into the sweeping robot. During the delivery process, the amount of cleaning agent added can be adjusted by adjusting the switch 23 to independently control the water supply process.

[0031] The sewage system and the ventilation system work together to collect sewage during the operation of the sweeping robot and discharge sewage after operation. The sewage end seat 33 is connected to the drainage part of the sweeping robot. The sweeping robot draws sewage into the sewage bottle 31 through negative pressure. When the negative pressure operation is completed, the one-way valve 34 at the bottom of the sewage bottle 31 opens to discharge sewage. Since the sewage bottle 31 is in a vacuum-sealed state during sewage discharge, the vacuum environment is switched through the operation of the ventilation system. Since the ventilation regulating switch 45 is installed on the main section of the air supply tee 42, it is used to control the air flow of the ventilation pipe 41, which can adjust the amount of air entering the sewage bottle 31, thereby adjusting the speed of sewage discharge.

[0032] Understandably, the liquid supply end cap 24 is plugged into the liquid inlet of the robot vacuum cleaner, and both cleaning agent and tap water are delivered to the robot vacuum cleaner through the liquid supply end cap 24.

[0033] To prevent sewage backflow, the sewage bottle 31 and the sewage pipe 35 are connected to form a sewage channel, and the one-way valve 34 is a one-way transmission structure to prevent sewage backflow.

[0034] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
