[0002] External detergent dispensers are typically installed on self-service washing machines. Users purchase and use detergent from the external dispenser when using the machine. Simply open the valve on the dispenser, and the detergent is dispensed into the washing machine through the dispensing pipe, thus completing the detergent dispensing process.

[0003] However, currently available external detergent dispensers have a significant drawback: they lack a dispensing detection device in their dispensing lines. If the dispensing pump malfunctions, the device cannot promptly alert the user of the dispensing failure. This results in detergent not being properly added to the washing machine during the washing process, severely impacting washing performance and failing to meet the user's basic requirements for clean clothes. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a liquid dosing detection device and a dosing pipeline. This liquid dosing detection device can effectively detect the liquid dosing status of the equipment and promptly alert the user to any abnormalities in the liquid dosing process.

[0005] In a first aspect, this utility model provides a liquid dosing detection device, including a liquid dosing detection port installed on a main pipeline. The liquid dosing detection port includes a liquid dosing detection housing connected to the main pipeline. The liquid dosing detection housing has a hollow structure and a through-hole is provided at one end. A movable magnetic valve core is installed inside the liquid dosing detection housing. The magnetic valve core cooperates with the through-hole to control the opening and closing of the through-hole. A magnetic induction switch corresponding to the magnetic valve core is installed on the liquid dosing detection housing.

[0006] In one embodiment of this utility model, a retaining ring is also installed inside the liquid dosing detection housing. The retaining ring is fixedly connected to the inner wall of the liquid dosing detection housing. A guide seat is abutted on one side of the retaining ring, and a spring is provided between the magnetic valve core and the guide seat.

[0007] In one embodiment of this utility model, the guide seat is provided with a guide hole and a plurality of flow holes surrounding the guide hole, and a web is provided between adjacent flow holes; the magnetic valve core includes a valve core head, a valve core tail, and a step fixedly connected between the valve core head and the valve core tail; the valve core head is movably inserted into the through-hole, the valve core tail is movably inserted into the guide hole, and the spring abuts against the plurality of webs of the guide seat and the step.

[0008] In one embodiment of this utility model, a sealing ring 103 is installed on the valve core head, and an inclined surface is provided on the inner wall of the liquid dosing detection housing near the port. The sealing ring is used for sealing between the magnetic valve core and the inclined surface of the inner wall of the liquid dosing detection housing.

[0009] In one embodiment of this utility model, the outer wall of the retaining ring is provided with protruding teeth, which are embedded in the inner wall of the liquid dosing detection housing.

[0010] In one embodiment of this utility model, the liquid dosing detection housing is provided with a mounting groove, and the magnetic induction switch is installed in the mounting groove.

[0011] In one embodiment of this utility model, the liquid dosing detection port includes a first liquid dosing detection port and a second liquid dosing detection port. The first liquid dosing detection port includes a first liquid dosing detection housing connected to the main pipeline, and the second liquid dosing detection port includes a second liquid dosing detection housing connected to the main pipeline.

[0012] In one embodiment of this utility model, the diameter of the valve core head of the first liquid dosing detection housing is ≤2mm, and the diameter of the valve core head of the second liquid dosing detection housing is ≥4mm.

[0013] In one embodiment of this utility model, the magnetic induction switch is a reed switch or a Hall element.

[0014] Secondly, this utility model provides a dispensing pipeline, including the aforementioned liquid dispensing detection device.

[0015] The present invention has the following beneficial effects:

[0016] This invention provides a liquid dosing detection device and dosing pipeline. By improving the structure of the liquid dosing detection housing, the valve core of the one-way valve is made into a movable magnetic valve core with a magnet. A corresponding magnetic induction switch is set on the outer wall of the liquid dosing detection housing, thus achieving both the one-way conduction function of the one-way valve and the purpose of liquid dosing detection of the dosing pump. Specifically, during normal liquid dosing, the dosing pump pumps out detergent, which enters the liquid dosing detection housing through the inlet, thereby pushing the magnetic valve core to move. The magnetic induction switch corresponds to the magnetic valve core, sensing changes in the magnetic field to switch on or off. The main controller determines the liquid dosing status of the dosing pump based on the switching changes of the magnetic induction switch. Therefore, this invention utilizes the change in the magnetic field caused by the movement of the magnetic valve core under the liquid dosing pressure of the dosing pump. The magnetic induction switch converts the change in the magnetic field into a switching signal, allowing the main controller to determine the liquid dosing status of the dosing pump based on the switching signal. This effectively detects the liquid dosing status of the equipment and promptly alerts the user to any abnormalities. This invention overcomes the functional deficiencies of current products on the market and improves the liquid dosing detection function of detergent dosing equipment. Attached Figure Description

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this utility model provides a liquid dosing detection device, including a liquid dosing detection port installed on the main pipeline 3. The liquid dosing detection port includes a liquid dosing detection housing connected to the main pipeline 3. The liquid dosing detection housing has a hollow structure and a through port 109 at one end. A movable magnetic valve core 104 is installed inside the liquid dosing detection housing. The magnetic valve core 104 cooperates with the through port 109 to control the opening and closing of the through port 109. A magnetic induction switch 102 corresponding to the magnetic valve core 104 is installed on the liquid dosing detection housing.

[0029] In some embodiments, a retaining ring 107 is also installed inside the liquid dosing detection housing. The retaining ring 107 is fixedly connected to the inner wall of the liquid dosing detection housing. One side of the retaining ring 107 abuts against a guide seat 106. A spring 105 is provided between the magnetic valve core 104 and the guide seat 106.

[0030] In some embodiments, the guide seat 106 is provided with a guide hole 1061 and a plurality of flow holes 1062 surrounding the guide hole 1061, and a web plate 1063 is provided between adjacent flow holes 1062; the magnetic valve core 104 includes a valve core head 1041, a valve core tail 1043, and a step 1042 fixedly connected between the valve core head 1041 and the valve core tail 1043; the valve core head 1041 is movably inserted into the through port 109, the valve core tail 1043 is movably inserted into the guide hole 1061, and the spring 105 abuts against the plurality of web plates 1063 and the step 1042 of the guide seat 106.

[0031] In this embodiment, the valve core guide seat 106 has a circular structure, with a central guide hole 1061 through which the valve core tail 1043 passes, serving as a guide for the valve core tail 1043; and flow holes 1062 arranged around the perimeter allow detergent to flow through them. A spring 105 is installed between several webs 1063 of the guide seat 106 and the steps 1042 of the magnet valve core 104, and the spring force of the spring 105 can reset the magnet valve core 104.

[0032] In some embodiments, a sealing ring 103 is installed on the valve core head 1041, and an inclined surface 1010 is provided on the inner wall of the liquid dosing detection housing near the port 109. The sealing ring 103 is used for sealing between the magnetic valve core 104 and the inclined surface 1010 on the inner wall of the liquid dosing detection housing.

[0033] In this embodiment, the valve core head 1041 is movably inserted into the through-hole 109 of the liquid dosing detection housing. When the valve core head 1041 extends into the through-hole 109, the valve core head 1041 drives the sealing ring 103 to move toward the inclined surface 1010, so that the sealing ring 103 is squeezed between the valve core head 1041 and the inclined surface 1010 of the inner wall of the liquid dosing detection housing, thereby achieving a seal between the magnetic valve core 104 and the liquid dosing detection housing through the sealing ring 103.

[0034] In some embodiments, the outer wall of the retaining ring 107 is provided with protruding teeth 1071, which are embedded in the inner wall of the liquid dosing detection housing.

[0035] In this embodiment, the retaining ring 107 can be made of a metal ring and plastic. The outer wall of the retaining ring 107 can be provided with protruding metal teeth 1071. The metal teeth 1071 are interference-fitted with the inner wall of the liquid dosing detection housing, thereby realizing the fixed connection between the retaining ring 107 and the inner wall of the liquid dosing detection housing, preventing the retaining ring 107 from falling out, and ensuring the stable connection of the entire liquid dosing detection device.

[0036] In some embodiments, the liquid dosing detection housing is provided with a mounting groove 108, and the magnetic induction switch 102 is installed in the mounting groove 108.

[0037] In some embodiments, the liquid dosing detection housing is connected to the main pipeline 3 by a threaded connection, which facilitates disassembly and assembly.

[0038] In some embodiments, the liquid injection detection port includes a first liquid injection detection port 1 and a second liquid injection detection port 2. The first liquid injection detection port 1 includes a first liquid injection detection housing 101 connected to the main pipeline 3, and the second liquid injection detection port 2 includes a second liquid injection detection housing 201 connected to the main pipeline 3.

[0039] Furthermore, the diameter of the valve core head 1041 of the first liquid dosing detection housing 101 is ≤2mm, and the diameter of the valve core head 1041 of the second liquid dosing detection housing 201 is ≥4mm.

[0040] In this embodiment, the first liquid dosing detection port 1 can be a disinfectant liquid dosing detection port, used to detect the dosing status of the disinfectant liquid; the second liquid dosing detection port 2 can be a laundry detergent dosing detection port, used to detect the dosing status of the laundry detergent.

[0041] Because the disinfectant solution has a low viscosity, the dispensing pump has a flow rate of 40–50 ml / min. To ensure the proper functioning of the magnetic valve core 104, the diameter of the valve core head 1041 in the first dispensing detection housing 101 needs to be designed to be ≤2 mm. Because the laundry detergent has a high viscosity, the diameter of the valve core head 1041 in the second dispensing detection housing 201 needs to be designed to be ≥4 mm.

[0042] In some embodiments, the magnetic induction switch 102 is a reed switch or a Hall element.

[0043] The working principle of the liquid dosing detection device provided by this utility model is as follows:

[0044] When the dispensing pump is damaged or not working, there is no liquid flow in the pipeline. Under the elastic force of the spring 105, the magnetic valve core 104 drives the sealing ring 103 to move towards the inclined surface 1010, so that the sealing ring 103 is squeezed between the valve core head 1041 and the inclined surface 1010 of the inner wall of the liquid dispensing detection housing, thus sealing the magnetic valve core 104 and the liquid dispensing detection housing, thereby closing the pipeline. At this time, the magnetic field of the magnetic valve core 104 does not trigger the magnetic induction switch 102 to turn on or off.

[0045] When the dispensing pump is working normally, it squeezes the detergent in the pipeline from the inlet 109 into the main pipeline 3, pushing the magnetic valve core 104 forward. The magnetic field of the magnetic valve core 104 causes the magnetic induction switch 102 to turn on or off, so that the main controller connected to the magnetic induction switch 102 can sense the working status of the dispensing pump, thereby effectively detecting the liquid dispensing status of the equipment, promptly alerting the user to any abnormal liquid dispensing, ensuring that the detergent can be added normally into washing equipment such as washing machines, and guaranteeing the washing effect.

[0046] In addition, this utility model also provides a dispensing pipeline, including the above-mentioned liquid dispensing detection device.

[0047] The dispensing pipeline provided by this utility model is used to dispense detergent from the detergent dispensing device into the washing device to complete the detergent dispensing.

[0048] The washing equipment can be commercial washing equipment such as washing machines, dishwashers, shoe washing machines, dryers, and dry cleaning machines. Because the dispensing pipeline includes a liquid dispensing detection device for any of the above-mentioned devices, it possesses all the advantages described above.

[0049] In summary, existing dosing pumps have a one-way valve installed at the outlet, allowing detergent dispensed by the pump to enter the dosing pipeline while preventing tap water from entering the pump. However, this method cannot detect whether the pump's dispensing function is malfunctioning. The dosing detection device and dosing pipeline provided by this invention improves the structure of the dosing detection housing by making the valve core of the one-way valve structure a movable magnetic valve core 104 with a magnet. A corresponding magnetic induction switch 102 is installed on the outer wall of the dosing detection housing, simultaneously achieving the one-way conduction function of the one-way valve and the purpose of dosing pump detection. Specifically, during normal dosing, the pump dispenses detergent, which enters the dosing detection housing through the inlet 109, thereby moving the magnetic valve core 104. The magnetic induction switch 102 corresponds to the magnetic valve core 104; it senses changes in the magnetic field and switches on or off. The main controller determines the dosing status of the pump based on the switching changes of the magnetic induction switch 102. Therefore, this invention utilizes the change in magnetic field caused by the movement of the magnetic valve core 104 under the dispensing pressure of the dispensing pump. This change in magnetic field is converted into a switching signal by the magnetic induction switch 102, allowing the main controller to determine the dispensing status of the dispensing pump based on the switching signal. This effectively detects the dispensing status of the equipment and promptly alerts the user to any abnormalities. This invention overcomes the functional deficiencies of current products on the market and improves the dispensing detection function of detergent dispensing equipment.

It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
