[0044] According to the detergent dispensing control device 10 of the present utility model, please refer to Figure 1 and Figure 2 The detergent dispensing control device 10 includes a device body 100, a liquid pump 200, a detection module 300 and a control component (not shown in the figure), the device body 100 forms an installation space 101 for the detergent replacement package 30; the liquid pump 200 is connected to the device body 100, connected to the detergent replacement package 30, and the device body 100 and the liquid pump 200 form a detergent flow path; the detection module 300 is arranged in the detergent flow path; the control component is arranged in the device body 100, and the control component controls the opening and closing of the liquid pump 200 based on the judgment result of the detection module 300.

[0045] According to the detergent dispensing control device 10 of the embodiment of the utility model, by setting the detection module 300 on the detergent flow path, the detergent can generate a detection signal when passing through the detection module 300, which can effectively determine whether the current detergent replacement package 30 still has detergent remaining, effectively reduce the number of empty suction times of the liquid pump 200, thereby extending the service life of the liquid pump 200, and effectively reduce the abnormal noise of empty suction.

[0046] It should be noted that the detergent dispensing control device 10 of the present invention can be installed in an existing cleaning device, or can be installed as a part of the cleaning device. When the detergent dispensing control device 10 is installed as a part of the existing cleaning device, the device body 100 can be fixed in the installation space 101 of the cleaning device, and connected to the liquid pump 200, the detection module 300 and the control component.

[0047] By cooperating with the control system of the cleaning equipment, intelligent control of detergent delivery can be achieved. When the detergent delivery control device 10 is used as an independent device, the device body 100 is an independent device with its own control system and operation interface. The user can place the detergent replacement package 30 in the device body 100, and control the opening and closing of the liquid pump 200 through the control component, thereby realizing intelligent delivery of detergent.

[0048] It can be understood that the device body 100 is the main part of the detergent dispensing control device 10, which is used to install and fix other components, such as the liquid pump 200, the detection module 300 and the control component, and provides an installation space 101 for the detergent replacement package 30.

[0049] It is understandable that the detergent replacement package 30 refers to a replaceable cleaning consumable containing detergent. The detergent replacement package 30 includes a detergent container with good airtightness. The detergent replacement package 30 can be provided with a dedicated installation interface for the detergent dispensing control device 10, and the liquid pump 200 can be connected to the detergent inside the detergent replacement package 30 through the installation interface.

[0050] By using the detergent replacement package 30, the user can easily replace the detergent without having to add detergent every time, thereby simplifying the operation steps and improving the use efficiency. At the same time, since the detergent replacement package 30 is replaceable, the user can purchase a new detergent replacement package 30 when needed instead of the entire cleaning device, thereby reducing the use cost and maintenance cost. The user can directly replace the detergent replacement package 30, avoiding the defect of cumbersome operation of adding detergent and reducing the possibility of splashing detergent and contaminating the surface of the device during the process of adding detergent.

[0051] It is understandable that the liquid pump 200 is used to extract the detergent in the detergent replacement package 30 and deliver it to the detergent flow path on the device body. The device body 100 and the liquid pump 200 form a detergent flow path, which means that the device body 100 and the liquid pump 200 are connected to each other to form a closed or semi-closed detergent delivery system. Specifically, when the detergent is extracted from the detergent replacement package 30, it passes through the channel or pipeline inside the device body 100 and then enters the liquid pump 200, or directly enters the liquid pump 200, and the liquid pump 200 delivers the detergent to the guide component of the device body, and then delivers it to the items to be washed.

[0052] It is understandable that the detection module 300 is used to detect the flow state of the detergent to determine whether there is any detergent remaining in the current detergent replacement package 30. The detection module 300 generally includes components such as sensors, which can sense the state or parameters of the detergent and convert them into electrical signals or other forms of signals and transmit them to the control component.

[0053] It is understandable that the control component can determine whether it is necessary to continue extracting detergent based on the signal of the detection module 300 and control the working state of the liquid extraction pump 200.

[0054] It should be noted that the detergent refill 30 may also be a refill of a flexible package, and in this case the corresponding detection module may be a gravity sensor corresponding to the flexible package.

[0055] According to an embodiment of the present invention, please refer to Figure 1 and Figure 2 The detection module 300 includes a first detection component 310, and the first detection component 310 includes a first electrode 311 and a second electrode 312. The first electrode 311 and the second electrode 312 are arranged in the detergent flow path, and the first electrode 311 and the second electrode 312 are suitable for being turned on when the detergent flows through.

[0056] It can be understood that there is a voltage difference between the first electrode 311 and the second electrode 312. When the first electrode 311 and the second electrode 312 are air, it is equivalent to an open circuit. When the detergent connects the first electrode 311 and the second electrode 312, the first electrode 311 and the second electrode 312 are connected to form a current. The state or parameters of the detergent can be judged by the conduction or the change of the conduction state.

[0057] It should be noted that different liquids have different electrical conductivities, so different voltage and current values ​​are generated when flowing through the first electrode 311 and the second electrode 312. By comparing different current values ​​with characteristic values ​​measured in advance, it can be determined whether detergent flows through the first electrode 311 and the second electrode 312.

[0058] It should be noted that the specific shape, size, material, etc. of the first electrode 311 and the second electrode 312 can be selected and designed according to actual needs to adapt to different detergent state or parameter detection needs. At the same time, the conduction or change of the conduction state of the first electrode 311 and the second electrode 312 can also be used to detect and control the detergent state or parameter through appropriate circuits or logical judgments, and the utility model does not make specific limitations on this.

[0059] According to an embodiment of the present invention, please refer to Figure 2 and Figure 3 The device body 100 further includes a guide plate 110 , which is disposed below the liquid outlet 210 of the liquid pump 200 . The guide plate 110 forms a partial detergent flow path. The first electrode 311 and the second electrode 312 are disposed corresponding to the guide surface 111 .

[0060] It is understandable that the guide plate 110 is disposed below the liquid outlet 210 of the liquid pump 200 to guide the flow direction of the detergent. The guide plate 110 may have a certain inclination angle to adapt to the natural flow trend of the detergent and further optimize the flow path of the detergent.

[0061] The guide plate 110 forms part of the detergent flow path, and together with the channel or pipe inside the device body 100, forms a complete detergent flow path. The design of the guide plate 110 can ensure that the detergent passes through the liquid pump 200 and the detection module 300 more stably and evenly during the flow process.

[0062] The first electrode 311 and the second electrode 312 correspond to the surface of the guide plate 110 and are arranged along the direction of the guide surface 111. Specifically, the first electrode 311 and the second electrode 312 can be formed on the guide plate 110, or can be located above the guide plate 110 and arranged corresponding to the guide surface 111.

[0063] According to an embodiment of the present invention, please refer to Figure 1 and Figure 2 The detection module 300 also includes a second detection component 320, which is disposed on the device body 100 and is used to detect whether the detergent replacement package 30 is replaced.

[0064] It is understandable that the second detection component 320 can be disposed inside the device body 100. When the detergent replacement package 30 is replaced, the second detection component 320 can detect the replacement status of the detergent replacement package 30 and send a corresponding signal to the control component. After receiving the signal from the second detection component 320, the control component determines that the installation status of the detergent replacement package 30 has changed. If the installation status of the detergent replacement package 30 has not changed, it can control the liquid pump 200 to keep stopping working, and issue a corresponding prompt or warning message to notify the user to replace the detergent replacement package 30. At the same time, it can also stop the detection work of the first detection component 310 to avoid waste of resources.

[0065] It should be noted that the second detection component 320 can adopt a contact sensor or a non-contact sensor, wherein the contact sensor can be an electromagnet, a micro switch, etc., and the non-contact sensor can be a laser sensor, an infrared sensor, etc., and the utility model does not make specific limitations on this.

[0066] Taking the second detection component 320 as an electromagnet as an example, when the detergent refill 30 is installed on the device body 100, the electromagnet's attraction action can be triggered, thereby sending a signal to replace the detergent refill 30.

[0067] Taking the second detection component 320 as an infrared sensor as an example, when the detergent refill 30 is installed on the device body 100, it can be determined whether it has been replaced by detecting specific characteristics (such as reflectivity, transmittance, etc.) of the detergent refill 30. When a change in the characteristic is detected, the sensor can send a corresponding signal to the control component.

[0068] According to an embodiment of the present invention, the second detection component 320 is a micro switch, which is disposed in the installation space 101. When the detergent replacement package 30 is disassembled or assembled, the state of the micro switch changes.

[0069] It is understandable that the micro switch is disposed in the installation space 101, usually near the installation position of the detergent refill 30. When the detergent refill 30 is correctly installed on the device body 100, a certain part of the detergent refill 30 contacts the micro switch, triggering the opening and closing action of the micro switch. When the detergent refill 30 is removed or replaced, the state of the micro switch will also change accordingly. For example, if the micro switch was originally in a closed state, when the detergent refill 30 is removed, the micro switch will become an open state.

[0070] After the control component receives the state change signal of the micro switch, if the control component determines that replacement is needed, it can automatically control the liquid pump 200 to stop working and issue a corresponding prompt or warning message to notify the user to replace the detergent replacement package 30.

[0071] In one embodiment, please refer to Figure 5 The detergent refill 30 is provided with a switch protrusion 31. When the detergent refill 30 is installed in place in the installation space 101, the switch protrusion 31 will lift the micro switch to switch the state. When the detergent refill 30 is removed, the micro switch is not lifted.

[0072] According to an embodiment of the present invention, please refer to Figure 1 The detergent dispensing control device 10 further includes a pump mounting frame 400 , which is connected to the device body 100 and is located outside the device body 100 , and the liquid pump 200 is mounted on the pump mounting frame 400 .

[0073] It is understandable that the pump mounting frame 400 is used to support and fix the liquid pump 200 so that the liquid pump 200 can work stably and ensure the accurate delivery and control of the detergent. The pump mounting frame 400 is located outside the device body 100 to facilitate observation of the working state of the liquid pump 200 and to facilitate installation and disassembly. Through the pump mounting frame 400, the liquid pump 200 can be quickly and easily installed on the device body 100, which improves the maintainability and operability of the equipment. In addition, since the pump mounting frame 400 is located outside the device body 100, it can effectively reduce the interference and influence of the liquid pump 200 on the inside of the detergent delivery control device 10. This can ensure that the various components inside the device can work more stably and improve the performance and reliability of the entire device.

[0074] According to an embodiment of the present invention, please refer to Figure 4 The device body 100 is provided with a plurality of delivery ports 600, and the delivery ports 600 are connected to the washing space 21 of the part to be connected. It is understandable that the delivery port 600 can be used to deliver detergents other than the detergent replacement package 30. By providing a plurality of delivery ports 600, the user can add different types of detergents more flexibly to meet different washing needs. For example, the user can deliver laundry detergent in one delivery port 600, deliver softener in another delivery port 600, or deliver different detergent ingredients in more delivery ports 600, and can select a suitable detergent combination according to different washing needs, so that the washing is more thorough and uniform.

[0075] The part to be connected can be understood as the equipment body 20 of the cleaning equipment. A washing space 21 is provided inside the equipment body 20 , and the delivery port 600 is connected to the internal washing space 21 .

[0076] In one embodiment, please refer to Figure 1 The device body 100 is also provided with a switch component 500, which is used to control the connection between the delivery port 600 and the washing space 21 of the device body 20. For example, when the user needs to add detergent, the switch component 500 can open the delivery port 600 to allow the detergent to flow into the washing space 21; when the washing process starts, the switch component 500 can close the delivery port 600 to start the washing cycle.

[0077] Specifically, the on-off component 500 may be a solenoid valve or a liquid pump 200 .

[0078] The cleaning device according to the second embodiment of the utility model comprises a device body 20 and the above-mentioned detergent dispensing control device 10. A washing space 21 is formed inside the device body 20, and the above-mentioned detergent dispensing control device 10 is connected to the device body 20, and the detergent flow path is connected to the washing space 21. The cleaning device combines the device body 20 and the detergent dispensing control device 10 to realize intelligent control of washing.

[0079] It should be noted that cleaning equipment includes various types, which may be dishwashers, pot cleaning equipment, washing machines and other equipment that require detergents, and the present utility model does not impose specific restrictions on this.

[0080] According to an embodiment of the present invention, the detergent dispensing control device 10 is disposed on the top of the device body 20 .

[0081] It is understandable that the detergent dispensing control device 10 is arranged on the top of the device body 20, so that the user does not need to bend down or find a suitable position when adding detergent or performing other operations. This design takes into account the convenience of user use and improves the user experience.

[0082] Since the detergent dispensing control device 10 is arranged on the top of the equipment body 20, the detergent extracted by the liquid pump 200 can automatically flow into the washing space 21 below by utilizing the action of gravity when being dispensed. This natural falling method can reduce the use of mechanical parts and reduce the complexity and maintenance cost of the equipment.

[0083] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
