Description

Technical Field

[0001] The utility model relates to a liquid leakage detection device for detergent dispensing equipment, belonging to the technical field of washing equipment. Background Art

[0002] The external detergent dispenser is generally configured on the self-service washing machine. When the user uses the self-service washing machine, he purchases and uses the detergent in the external detergent dispenser. That is, after the valve of the external detergent dispenser is opened, the detergent in the external detergent dispenser flows out.

[0003] However, most of the external detergent dispensing devices currently available on the market have an inverted liquid bottle structure. When the temperature rises significantly in the environment in which the device is used, the air inside the liquid bottle storing the detergent expands due to the heat, which can easily squeeze the detergent out of the bottle, causing detergent leakage. In addition, after long-term use, aging and failure of the internal seals of the device can also cause detergent or tap water leakage. If the device cannot detect liquid leakage in time, not only will the leakage damage the device, but it will also cause a waste of detergent or tap water, causing economic losses to users, and even serious safety accidents, such as fires caused by electrical short circuits, or accidents such as slips and injuries.

[0026] like Figure 1 and Figure 2As shown, the utility model provides a leakage detection device for a detergent dispensing device, comprising a first detergent storage bottle 1 and a second detergent storage bottle 2, the first detergent storage bottle 1 and the second detergent storage bottle 2 are respectively invertedly mounted on a first storage tank cover plate 3 and a second storage tank cover plate 4; the first storage tank cover plate 3 and the second storage tank cover plate 4 are mounted on a storage tank 5; the storage tank 5 is fixedly mounted on a back plate 6; the back plate 6 is connected to a lower cover 7, and the back plate 6 and the lower cover 7 are butted against each other to enclose the storage tank 5 between the back plate 6 and the lower cover 7. Specifically, the lower cover 7 is pushed in from the front of the back plate 6, and can be fixedly connected to the back plate 6 by screws.

[0027] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a first overflow notch 501 and a second overflow notch 502 are provided on the liquid storage tank 5; an overflow liquid collecting groove 504 for receiving the overflow liquid is provided on one side of the first overflow notch 501 and the second overflow notch 502, and an overflow liquid outflow channel 503 is connected below the overflow liquid collecting groove 504.

[0028] When the gas inside the first detergent storage bottle 1 or the second detergent storage bottle 2 expands and the detergent in the bottle is squeezed out of the bottle, the liquid first flows into the liquid storage tank 5. When the liquid level of the liquid storage tank 5 exceeds the lower edge of the first overflow notch 501 and the second overflow notch 502, the overflowed detergent will flow out from the first overflow notch 501 or the second overflow notch 502. The detergent flowing out from the first overflow notch 501 or the second overflow notch 502 will flow into the overflow liquid collection groove 504. The overflow liquid collection groove 504 is connected to an overflow liquid outflow channel 503 in the middle, which is used to guide the detergent in the overflow liquid collection groove 504 downward.

[0031] Furthermore, the bottom end of the liquid accumulation groove 703 is lower than the bottom end of the overflow liquid flow channel 603. Through the above arrangement, the bottom of the liquid accumulation groove 703 is at the lowest point of the entire device, so that the leaked liquid can be finally collected in the liquid accumulation groove 703.

The lower part of the lower cover 7 is provided with a liquid accumulation groove 703, and the bottom of the liquid accumulation groove 703 is at the lowest point of the entire device. A first liquid leakage detection coupling socket 701 and a second liquid leakage detection coupling socket 702 with a liquid leakage detection probe are provided in the middle of the liquid accumulation groove 703.

[0035] Furthermore, one side of the first liquid leakage detection coupling socket 701 and the second liquid leakage detection coupling socket 702 are both fixedly connected with a liquid level probe 704 , and the bottom of the liquid level probe 704 extends into the bottom of the liquid accumulation groove 703 .

[0036] Furthermore, the first liquid leakage detection coupling socket 701 and the second liquid leakage detection coupling socket 702 are both formed by bending stainless steel sheets and are fixedly connected to the liquid level probe 704 .

[0037] In this embodiment, the first liquid leakage detection coupling socket 701 and the second liquid leakage detection coupling socket 702 are both formed by bending a stainless steel sheet, and a strip-shaped liquid level probe 704 is fixedly connected to the side. The bottom of the liquid level probe 704 extends into the bottom of the liquid accumulation groove 703 as a probe for liquid level detection.

Once the temperature of the liquid storage bottle rises abnormally and the liquid in the bottle begins to overflow, the liquid will overflow from the dedicated overflow notch and pass through the overflow liquid collection groove, the overflow liquid outflow channel, and the overflow liquid flow channel in sequence to reach the liquid accumulation groove. The liquid level probe installed in the liquid accumulation groove detects the leakage, and the device will promptly inform the user to handle it. The liquid leakage detection device for the detergent dispensing device has a simple structure and is easy to manufacture, which can help users detect liquid leakage and water leakage problems in a timely manner and reduce losses.
