Description

Technical Field

[0001] This utility model relates to a liquid detection device and a liquid dispenser, belonging to the field of liquid dispenser technology. Background Technology

[0002] Currently, most commercially available automatic liquid dispensers lack liquid detection capabilities and cannot monitor the remaining liquid level in the storage bottle in real time. During use, users can only visually observe the liquid level or discover the liquid is depleted only when dispensing fails. This reliance on manual judgment has significant drawbacks, especially when automatic dispensers are deployed in public places as shared equipment. The problem becomes even more pronounced: equipment administrators struggle to keep track of remaining cleaning fluid levels, hindering timely replenishment or maintenance and impacting the continuous normal operation of the equipment.

[0003] Furthermore, if a user fails to dispense liquid due to running out of liquid during the dispensing process, but the equipment still charges according to the normal procedure, it will lead to user complaints and a decline in user experience, which is not conducive to the promotion and operation of the equipment. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a liquid detection device and a liquid dispenser. The liquid detection device can monitor the liquid dispensing status in real time, detecting whether the dispensing is normal. In the event of dispensing failure, it promptly alerts the administrator to replenish the liquid or perform maintenance, thereby ensuring reliable equipment operation and improving user satisfaction.

[0005] In a first aspect, this utility model provides a liquid detection device, including a liquid detection pipe, and a positive and negative detection probe installed on the liquid detection pipe. The head of the positive detection probe and the head of the negative detection probe are connected to the interior of the liquid detection pipe.

[0022] like Figures 1 to 7 As shown, this utility model provides a liquid detection device 5, which includes a liquid detection pipe 507, and a positive electrode 501 and a negative electrode 502 of a detection probe installed on the liquid detection pipe 507. The head of the positive electrode 501 and the head of the negative electrode 502 are connected to the interior of the liquid detection pipe 507. The liquid detection device 5 is installed on a dispensing device body 8 via a mounting bracket 6. The dispensing device body 8 is equipped with a storage bottle 1 and a pump 3. The storage bottle 1 is connected to the suction port of the pump 3 via a pump suction pipe 2. The outlet of the pump 3 is connected to a pump outlet pipe 4. The other end of the pump outlet pipe 4 is connected to the liquid detection pipe 507. The end of the liquid detection pipe 507 away from the pump outlet pipe 4 is connected to an outlet pipe 7.

[0023] In some embodiments, the storage bottle 1 is vertically installed on the dispensing device body 8 and is connected to the pump suction pipe 2 through a pipe extending into the storage bottle 1. The other end of the pump suction pipe 2 is connected to the suction port of the pump 3.

[0024] The liquid detection device 5 provided by this utility model is installed at the end of the pump outlet pipe 4 of the pump 3, closest to the outlet pipe 7 of the 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 that the detection result is inconsistent with the actual liquid volume obtained by the user due to pipeline leakage.

[0025] In some embodiments, the liquid detection pipe 507 is arranged vertically.

[0026] In this embodiment, the liquid detection pipe 507 of the liquid detection device 5 is installed almost vertically, which can avoid residual liquid in the liquid detection pipe 507 from affecting the detection accuracy compared with horizontal installation.

[0027] In some embodiments, the positive electrode 501 and the negative electrode 502 of the detection probe are both screw-shaped structures, which are screwed onto the liquid detection pipeline 507 and sealed to the liquid detection pipeline 507.

[0028] In this embodiment, the positive electrode 501 and negative electrode 502 of the screw-shaped detection probe are sealed to the liquid detection pipe 507 through a self-tapping thread structure.

[0029] In some embodiments, the positive electrode 501 of the detection probe is connected to the positive electrode lead-out terminal 503 of the detection probe, and the negative electrode 502 of the detection probe is connected to the negative electrode lead-out terminal 504 of the detection probe.

[0030] In this embodiment, the positive terminal 501 of the detection probe is connected to the main control board of the liquid dispenser via a lead wire from the positive terminal 503 of the detection probe, and the negative terminal 502 of the detection probe is connected to the main control board of the liquid dispenser via a lead wire from the negative terminal 504 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.

[0031] In some embodiments, the distance between the positive electrode 501 and the negative electrode 502 of the detection probe is greater than 3 mm and less than 20 mm.

[0032] In this embodiment, after the positive electrode 501 and negative electrode 502 of the detection probe are screwed into the liquid detection pipe 507, the head of the detection probe extends into the liquid detection pipe 507. The inner diameter of the liquid detection pipe 507 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 507 from affecting the detection accuracy, it is recommended that the distance between the positive electrode 501 and the negative electrode 502 of the detection probe be greater than 3mm. Simultaneously, for the accuracy of the detection data, the distance between the positive electrode 501 and the negative electrode 502 of the detection probe should not be too large, and it is recommended to be less than 20mm. The length of the detection probe extending into the liquid detection pipe 507 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 507 can be less than 0 to avoid residual liquid affecting the detection results.

[0033] In some embodiments, the liquid level detection device 5 further includes a mounting hole 505 and a mounting buckle 506 disposed outside the liquid detection pipe 507, and the mounting bracket 6 is provided with a fixing hole 602 that is connected to the mounting hole 505 and a fixing groove 601 that is connected to the mounting buckle 506.

[0034] In this embodiment, when the liquid level detection device 5 is installed with the mounting bracket 6, it is pre-installed by connecting the mounting buckle 506 with the fixing slot 601 of the mounting bracket 6, and then the screw is tightened through the mounting hole 505 and the fixing hole 602.

[0035] In some embodiments, a shut-off valve 701 is installed inside the outlet port 7.

[0036] In some embodiments, the liquid outlet 7 is threadedly connected to the liquid detection pipe 507.

[0037] In this embodiment, when the pump 3 stops working, the pipeline is filled with cleaning fluid. Without the shut-off valve 701, the cleaning fluid will flow downwards due to gravity, resulting in waste and ground pollution. With the shut-off valve 701 installed, the cleaning fluid will not flow out of the pipeline. When the pump 3 restarts, the pressure inside the pipeline increases, opening the shut-off valve 701, allowing the cleaning fluid to flow out normally. Furthermore, the shut-off valve 701 prevents the liquid from contacting air, thus avoiding moisture evaporation and subsequent drying and pipeline blockage, ensuring reliable equipment operation. The shut-off valve 701 can be made of silicone.

[0038] Furthermore, this utility model also provides a liquid dispensing device, including the aforementioned liquid detection device. Because the liquid dispensing device includes any of the aforementioned liquid detection devices, it possesses all the advantages described above.

[0039] In summary, this utility model provides a liquid detection device and a liquid dispenser. The liquid detection device 5 is installed at the end of the pump outlet pipe 4 of the pump 3, closest to the outlet pipe 7 of the dispenser. It can accurately detect whether the liquid dispensed to the user meets the set value, and at the same time avoid the problem of discrepancies between the detection result and the actual liquid volume obtained by the user due to pipeline leakage. The liquid detection device 5 achieves real-time detection of the liquid dispensing status with fewer components, and can detect whether the liquid dispensing of the dispenser is normal. In the event of liquid dispensing failure, it promptly alerts the administrator to replenish the liquid or carry out maintenance, thereby ensuring reliable equipment operation and improving user satisfaction. The liquid detection device 5 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.
