[0044] Referring to Figure 1 and Figure 5 , a cleaning device 1000 provided by an embodiment of the present application is mainly used for cleaning a ceramic inner liner 2100 of an intelligent toilet 2000. Referring to Figure 1 and Figure 2As shown, the cleaning device 1000 comprises a liquid inlet part 110, a liquid outlet part 120 and a pressurizing part 200, the pressurizing part 200 is located between the liquid inlet part 110 and the liquid outlet part 120, the liquid inlet part 110 is provided with a liquid inlet channel 111, the pressurizing part 200 is provided with a pressurizing channel 210, the liquid outlet part 120 is provided with a liquid outlet 121, the pressurizing channel 210 connects the liquid inlet channel 111 and the liquid outlet 121, the pressurizing channel 210 has a pressurizing function, when the liquid flows from the liquid inlet channel 111 into the pressurizing channel 210, the dynamic pressure of the liquid will increase.

[0045] Specifically, referring to Figure 2 As shown, the pressurizing channel 210 connects the liquid inlet channel 111 and the liquid outlet 121, which can be understood as that the liquid inlet channel 111, the pressurizing channel 210 and the liquid outlet 121 are sequentially arranged along the water outlet direction, the water outlet direction can refer to the direction of the dashed arrow in Figure 2 The liquid entering the liquid inlet part 110 sequentially passes through the liquid inlet channel 111, the pressurizing channel 210 and the liquid outlet 121, the minimum cross-sectional area of the inner peripheral wall of the liquid inlet channel 111 is greater than the minimum cross-sectional area of the inner peripheral wall of the pressurizing channel 210, and the center line of the pressurizing channel 210 is perpendicular to the liquid outlet 121, the center line of the pressurizing channel 210 can be understood as the axis of the pressurizing channel 210, and it can also be understood that the center line of the pressurizing channel 210 is arranged along the extension direction of the pressurizing channel 210.

[0046] The present embodiment sets the liquid inlet channel 111 and the pressurizing channel 210, because the minimum cross-sectional area of the inner peripheral wall of the liquid inlet channel 111 is greater than the minimum cross-sectional area of the inner peripheral wall of the pressurizing channel 210, when the liquid sequentially passes through the liquid inlet channel 111 and the pressurizing channel 210, the cross-sectional area of the liquid passing through the channel is in a decreasing trend, which can increase the flow speed of the liquid, thereby increasing the dynamic pressure of the liquid, allowing the liquid to be sprayed farther from the liquid outlet 121, the principle is similar to the Venturi effect, and the center line of the pressurizing channel 210 is perpendicular to the liquid outlet 121, so that the spraying direction of the pressurizing channel 210 is the same as the liquid outlet direction of the liquid outlet 121, which can reduce the resistance to the liquid, reduce the consumption of the liquid, and further increase the spraying distance of the liquid, the present embodiment can achieve the pressurizing effect without setting a pressurizing pump, which can save manufacturing cost.

[0047] It should be noted that clean water or foam liquid can be introduced into the cleaning device 1000 of the present embodiment, the cleaning device 1000 increases the dynamic pressure of the clean water or foam liquid before spraying it out of the liquid outlet 121, thereby increasing the spraying distance of the clean water or foam liquid, if the foam liquid is introduced into the cleaning device 1000, the cleaning device 1000 can be understood as a foam shield device.

In other embodiments, the cross-sectional area of the inner circumferential wall of the liquid inlet channel 111 can be constant, and the cross-sectional area of the inner circumferential wall of the pressurizing channel 210 can gradually decrease along the water outlet direction, and when the liquid flows from the liquid inlet channel 111 into the pressurizing channel 210, the flow rate of the liquid can also be increased.
