The suction pump assembly 3 has a simple structure, reliable sealing, and low cost. It can maintain a stable sealing effect in long-term humid and hot environments. Through optimized structural design, the pump housing 32 is reserved with a first external interface 321 for liquid inlet, a second external interface 322 for liquid outlet, and a lead-out groove 324 for leading out the lead wire of the suction pump 33. The assembly is sealed by a glue-filling groove 311 set between the side wall of the cover 314 and the side wall of the pump housing 32, thereby effectively improving the overall waterproof capability of the suction pump assembly 3, expanding its application range, improving its environmental adaptability, and increasing the service life and reliability of the whole machine.

[0052] like Figure 7 , Figures 19 to 23 As shown, a liquid detection component 4 is provided between the pump outlet pipe 35 and the outlet pipe 11. The liquid detection component 4 is used to detect the liquid dispensing status of the cleaning liquid dispenser. The liquid dispensing status includes normal liquid dispensing and abnormal liquid dispensing. Normal liquid dispensing means that the cleaning liquid dispenser dispenses a set dose of cleaning liquid, and abnormal liquid dispensing means that the cleaning liquid dispenser does not dispense a set dose of cleaning liquid. The liquid detection component 4 is installed below the suction pump assembly 3 and above the storage bottle assembly 2. The liquid detection component 4 includes a liquid detection pipe 47 and a detection probe positive electrode 41 and a detection probe negative electrode 42 installed on the liquid detection pipe 47. The head of the detection probe positive electrode 41 and the head of the detection probe negative electrode 42 are connected to the interior of the liquid detection pipe 47. The liquid detection pipe 47 is installed on the rear cover 16 through a third mounting bracket 48. One end of the liquid detection pipe 47 is connected to the outlet of the pump outlet pipe 35, and the other end of the liquid detection pipe 47 is connected to the inlet of the outlet pipe 11.

[0053] In some embodiments, the liquid detection pipe 47 is arranged vertically. In this embodiment, the liquid detection pipe 47 is installed almost vertically, which avoids residual liquid in the liquid detection pipe 47 from affecting the detection accuracy compared to horizontal installation.

[0054] In some embodiments, both the positive electrode 41 and the negative electrode 42 of the detection probe are screw-shaped structures, which are screwed onto the liquid detection pipe 47 and sealed to it. In this embodiment, the screw-shaped positive electrode 41 and the negative electrode 42 of the detection probe are sealed to the liquid detection pipe 47 through a self-tapping thread structure.

[0055] In some embodiments, the positive terminal 41 of the detection probe is connected to the positive terminal lead 43 of the detection probe, and the negative terminal 42 of the detection probe is connected to the negative terminal lead 44 of the detection probe. In this embodiment, the positive terminal 41 of the detection probe is connected to the main control board of the liquid dispenser through the positive terminal lead 43 of the detection probe, and the negative terminal 42 of the detection probe is connected to the main control board of the liquid dispenser through the negative terminal lead 44 of the detection probe. The detection probe uploads the detected liquid dispensing status of the liquid dispenser to the main control board of the liquid dispenser, and promptly notifies the administrator to replenish the liquid or perform maintenance when liquid dispensing fails.

[0056] In some embodiments, the distance between the positive electrode 41 and the negative electrode 42 of the detection probe is greater than 3 mm and less than 20 mm. In this embodiment, after the positive electrode 41 and the negative electrode 42 of the detection probe are screwed into the liquid detection pipe 47, the head of the detection probe extends into the liquid detection pipe 47. The inner diameter of the liquid detection pipe 47 and the diameter of the detection probe can be adjusted accordingly based on the required liquid volume of the dispensing device. To prevent residual liquid in the liquid detection pipe 47 from affecting the detection accuracy, it is recommended that the distance between the positive electrode 41 and the negative electrode 42 of the detection probe be greater than 3 mm. At the same time, for the accuracy of the detection data, the distance between the positive electrode 41 and the negative electrode 42 of the detection probe should not be too large, and it is recommended to be less than 20 mm. The length of the detection probe extending into the liquid detection pipe 47 can be flexibly adjusted according to the viscosity of the internal detection liquid. When the viscosity of the detection liquid is high, the length of the detection probe extending into the liquid detection pipe 47 can be less than 0 to avoid residual liquid affecting the detection results.

[0057] In some embodiments, the liquid detection assembly 4 further includes a second mounting hole 45 and a mounting buckle 46 disposed outside the liquid detection pipe 47, and a third mounting bracket 48 is provided with a fixing hole 482 corresponding to the second mounting hole 45 and a fixing groove 481 corresponding to the mounting buckle 46. In this embodiment, when the liquid detection pipe 47 and the third mounting bracket 48 are installed, they are pre-installed by engaging the mounting buckle 46 with the fixing groove 481 of the third mounting bracket 48, and then screws are used to pass through the second mounting hole 45 and the fixing hole 482 to tighten and fix them.

[0058] In some embodiments, the outlet 11 is threadedly connected to the liquid detection pipe 47.

[0059] In some embodiments, a shut-off valve 17 is installed inside the outlet port 11.

[0060] In this embodiment, when the suction pump assembly 3 stops working, the pipeline is filled with cleaning fluid. Without the shut-off valve 17, the cleaning fluid will flow downwards due to gravity, resulting in waste and ground pollution. With the shut-off valve 17 installed, the cleaning fluid will not flow out of the pipeline. When the suction pump assembly 3 restarts, the pressure inside the pipeline increases, opening the shut-off valve 17, allowing the cleaning fluid to flow out normally. Furthermore, the shut-off valve 17 prevents the cleaning fluid in the pipeline from contacting the outside air, thus avoiding moisture evaporation and subsequent drying and clogging of the pipeline, ensuring reliable equipment operation. The shut-off valve 17 can be made of silicone.

[0061] The liquid detection component 4 provided by this utility model is installed at the end of the pump outlet pipe 35 of the liquid suction pump assembly 3, closest to the outlet pipe 11 of the liquid dispenser. It can accurately detect whether the liquid dispensed to the user meets the set value; at the same time, it can avoid the problem of discrepancies between the detection result and the actual liquid volume obtained by the user due to pipeline leakage. This liquid detection component 4 achieves real-time detection of the liquid dispensing status with fewer components, and can detect whether the liquid dispensing of the dispenser is normal. When the detection probe detects an abnormal resistivity in the liquid, the dispenser will promptly issue an indicator light and sound to remind the manager and user that the equipment is low on liquid, and can promptly prompt the manager to replenish the liquid or carry out maintenance, thereby ensuring reliable operation of the equipment and improving user satisfaction. The liquid detection component 4 has a simple structure, reliable detection, low manufacturing cost, and strong applicability. It can also adjust the size of the detection probe according to the viscosity of the cleaning liquid dispensed by the dispenser, thereby adapting to various usage environments and having good versatility and expandability.
