[0075] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Embodiments of the present invention

[0076] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0077] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0078] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art will understand the specific meaning of these terms in this invention based on the specific circumstances.

[0079] This application provides a dispensing system 40 for use in a clothing processing device 1. The clothing processing device 1 has a drying function configured to dry clothes; it may also have a washing function configured to wash clothes. The clothing processing device 1 of this application may include a dryer, a washer-dryer combo, etc.

[0080] Please refer to Figures 1-2. The clothing processing equipment 1 may include a clothing processing cylinder 10, a box 20, a heat pump system, and a dispensing system 40.

[0081] Specifically, the housing 20 is roughly hexagonal in shape, commonly a cuboid, for ease of placement and use. The housing 20 can be made of engineering plastics or metal, offering good insulation and impact resistance. The front of the housing 20 features a control panel for user operation, integrating a touchscreen display and multiple operation buttons. The touchscreen display provides an intuitive and user-friendly interface, allowing users to easily select various garment processing programs, such as drying, steam care, and quick drying, to meet the needs of different garment materials and processing requirements. The operation buttons serve as auxiliary operation methods; users can press or rotate different buttons to start, pause, and adjust the working time of the garment processing equipment 1.

[0082] The garment processing drum 10 is installed inside the housing 20, which protects it. The housing 20 can be made of stainless steel to ensure sufficient strength and durability to withstand the strong centrifugal force generated by the high rotation during garment processing. This ensures that the garment processing drum 10 will not deform or be damaged during long-term use, thus guaranteeing the stability and reliability of the garment processing equipment 1. The garment processing drum 10 is generally a hollow cylinder, and its internal space can be rationally arranged according to the actual needs of the garments to accommodate different volumes and types of clothing. The garment processing equipment 1 also includes a front support 21, which is located inside the housing 20 and configured to support the front end of the garment processing drum 10. It is understood that the garment processing equipment 1 may also include a rear plate, which is located inside the housing 20 and configured to support the rear end of the garment processing drum 10.

[0083] Please refer to Figure 2. The front support 21 is provided with a clothing loading and unloading port 211 that connects to the inner cavity of the clothing processing cylinder 10. Users can put the clothing to be processed into the clothing processing cylinder 10 through the clothing loading and unloading port 211, or take out the processed clothing from the clothing processing cylinder 10.

[0084] Please refer to Figures 1 and 2. The garment processing device 1 also includes a door 23. The housing 20 includes a front panel 22, which is located in front of the front support 21 and has an opening that communicates with the garment processing cylinder 10. The door 23 is movable relative to the front panel 22 to open or close the opening. When the door 23 is closed, it can seal the opening to prevent external substances from entering or moisture from leaking out. The door 23 can be rotatably connected to the front panel 22, allowing the door 23 to open and close smoothly and facilitating user operation.

[0085] During the garment processing, the garment processing drum 10 can rotate. As the drum rotates, the garments move from the bottom to the top along with the rotating drum wall, and then fall back down under the influence of gravity, repeating this cycle. Under the combined effect of the rotation of the garment processing drum 10 and gravity, the garments are fully dispersed and their posture changed. This movement ensures that the garments are evenly distributed within the drum, guaranteeing that all parts of the garments are evenly heated and dried. This avoids localized overheating or uneven drying, greatly improving drying efficiency and effectiveness. It also helps reduce wrinkles, resulting in smoother garments after drying.

[0086] The heat pump system is connected to the clothes handling drum 10 system to provide hot airflow for drying, and condensate is generated during the operation of the heat pump system. The heat pump system includes an evaporator, which cools the hot airflow, causing the water vapor in the airflow to condense into liquid water, thereby achieving the dehumidification function. The heat pump system also includes a condenser, which releases heat into the airflow after it has been dried by the evaporator, raising the airflow temperature and forming a hot airflow for drying clothes. The dried hot airflow then continues to circulate and dry the clothes.

[0087] Referring to Figures 3 to 6, the dispensing system 40 includes a dispensing device 45, a liquid storage box 41, a piping assembly 42, a power unit 43, and an on / off control element 44. The liquid storage box 41 has a water storage chamber 411 and a care agent chamber 412; it is understood that the dispensing system 40 can be configured with two liquid storage boxes 41, one of which is configured to hold water and the other is configured to hold care agent; or, the internal space of the liquid storage box 41 is divided into a water storage chamber 411 and a care agent chamber 412 by a partition, with the water storage chamber 411 configured to hold water and the care agent chamber 412 configured to hold care solution.

[0088] It should be noted that the fluid in the water storage chamber 411 is water. The fluid in the care agent chamber 412 is a care solution, which may include, but is not limited to, detergent, fabric softener, and fragrance. The detergent is formulated to clean clothes and includes, but is not limited to, dry cleaning agents. Dry cleaning agents are formulations that can effectively remove dirt under waterless or slightly wet conditions. Dry cleaning agents can be organic solvents, which dissolve and adsorb dirt, thus removing it from the clothes and achieving cleaning. Fabric softener serves to soften, fluff, and eliminate static electricity in clothes. Fragrance enhancer is formulated to add fragrance to clothes.

[0089] The piping assembly 42 has at least two inlet ends, which are respectively connected to the water storage chamber 411 and the care agent chamber 412. The outlet end of the piping assembly 42 is connected to the dispensing device 45. The power unit 43 is connected to the piping assembly 42 to provide the necessary power for the system to draw clean water from the water storage chamber 411 and care agent from the care agent chamber 412, and pump the clean water and care agent to the dispensing device 45. The dispensing device 45 is connected to the piping assembly 42 and the garment handling cylinder 10. The on / off control element 44 is disposed on the piping assembly 42 and configured to control the on / off connection between the water storage chamber 411 and the dispensing device 45, and to control the on / off connection between the care agent chamber 412 and the dispensing device 45, so as to adjust the mixing ratio of water and care agent.

[0090] Specifically, this application connects the dispensing device 45 to the water storage chamber 411 and the care solution chamber 412 via the pipeline assembly 42, and the power device 43 is connected to the pipeline assembly 42 to generate power so that the water storage chamber 411 and the care solution chamber 412 can be dispensed into the garment processing drum 10 by the dispensing device 45. The on / off control element 44 is provided in the pipeline assembly 42 and is configured to control whether the liquid dispensed into the garment processing drum 10 by the dispensing device 45 is water from the water storage chamber 411 or care solution from the care solution chamber 412. This application controls the connection and disconnection between the water storage chamber 411 and the dispensing device 45 through the on / off control component 44, thereby controlling the amount of water in the water storage chamber 411 that is dispensed into the clothing treatment tube 10 through the dispensing device 45. The on / off control component 44 also controls the connection and disconnection between the care agent chamber 412 and the dispensing device 45, thereby controlling the amount of care solution in the care agent chamber 412 that is dispensed into the clothing treatment tube 10 through the dispensing device 45. This allows for adjustment of the mixing ratio of water and care agent in the clothing treatment tube 10, facilitating the care of clothing of different materials.

[0091] Referring to Figure 3, the piping assembly 42 includes a first flow path 421 and a second flow path 422. The first flow path 421 connects the water storage chamber 411 and the dispensing device 45, and the second flow path 422 connects the care agent chamber 412 and the dispensing device 45. In some embodiments, the on / off control element 44 includes a first control valve 441 and a second control valve 442. The first control valve 441 is disposed in the first flow path 421, and the second control valve 442 is disposed in the second flow path 422. Specifically, when the first control valve 441 is open, clean water can smoothly enter the dispensing device 45 through the first flow path 421. When the first control valve 441 is closed, the clean water flow path is cut off, and the dispensing device 45 will not receive clean water from the water storage chamber 411. The second control valve 442 is disposed in the second flow path 422 and is responsible for controlling the flow path of the care agent from the care agent chamber 412 to the dispensing device 45. Similar to the first control valve 441, when the second control valve 442 is open, the detergent can smoothly flow through the second flow path 422 to the dispensing device 45. When the second control valve 442 is closed, the detergent flow path is cut off, and the dispensing device 45 will not receive detergent from the detergent chamber 412. By precisely controlling the opening and closing states of the first control valve 441 and the second control valve 442, the liquid dispensed into the garment treatment drum 10 by the dispensing device 45 can be flexibly adjusted to be either water or detergent, and the mixing ratio of water and detergent can be precisely controlled to meet different garment treatment needs.

[0092] Referring to Figure 4, in some embodiments, the second flow path 422 connects to the first flow path 421, dividing the first flow path 421 into an outlet section 4211 and a confluence section 4212 at the connection point. The second flow path 422 connects to the dispensing device 45 through the confluence section 4212. The aforementioned first control valve 441 is located in the outlet section 4211. The first control valve 441 only controls the connection between the water storage chamber 411 and the dispensing device 45, while the second control valve 442 only controls the connection between the care agent chamber 412 and the dispensing device 45. This allows for precise control of the mixing ratio of water and care agent. It is understood that the first flow path 421 and the second flow path 422 can be in the form of pipes. Connecting the second flow path 422 to the first flow path 421 reduces the amount of piping required and makes the entire piping system more compact, reducing space occupation.

[0093] In some embodiments, the on / off control element 44 includes a three-way valve 443. One inlet of the three-way valve 443 is connected to the water storage chamber 411 through the water outlet section 4211, and the other inlet is connected to the care agent chamber 412 through the second flow path 422. The outlet is connected to the dispensing device 45 through the manifold section 4212. This simplifies the installation process, reduces the number of control valves, and reduces the space occupied.

[0094] Referring to Figure 4, in some embodiments, the dispensing device 45 includes a first nozzle 45a with a dispensing channel that communicates with the manifold 4212; the power unit 43 includes a water pump 433, which is disposed on the manifold 4212. Specifically, the water pump 433 is activated to draw clean water or cleaning solution from the first flow path 421 and the second flow path 422 and pump it to the dispensing device 45. When the liquid reaches the dispensing channel of the first nozzle 45a, the dispensing channel uses the pressure difference to disperse the liquid into tiny droplets. These tiny droplets can more evenly cover the clothing, improving the efficiency and effectiveness of clothing treatment. The first nozzle 45a can be in the form of an atomizing nozzle.

[0095] Referring to Figure 5, in some embodiments, the dispensing device 45 includes a second nozzle 45b. Referring also to Figures 7 and 8, in some embodiments, the second nozzle 45b has a jet channel 4513 and a first supply channel 4521 and a second supply channel 4531 connected to the jet channel 4513. The second supply channel 4531 is connected to the confluence section 4212. The power unit 43 is connected to the first supply channel 4521 and creates a negative pressure when flowing towards the jet channel 4513, driving the liquid in the liquid storage box 41 to flow through the second supply channel 4531 to the jet channel 4513, where it mixes with the kinetic fluid in the first supply channel 4521 and is dispensed into the clothing treatment drum 10. Specifically, when the power unit 43 is activated, it generates high-speed fluid, which is transported to the first supply channel 4521 through a pipe. The high-speed flowing fluid enters the jet channel 4513 from the first supply channel 4521, forming a negative pressure area within the jet channel 4513. The negative pressure environment can provide a power source for the second supply channel 4531, drawing clean water or care solution from the second supply channel 4531 into the spray channel 4513. Inside the spray channel 4513, the high-speed fluid and the low-speed flowing liquid (clean water or care solution) are fully mixed, so that the liquid is refined into uniform and tiny droplets, thereby significantly improving the coverage area and uniformity of the water or care solution spray.

[0096] The power unit 43 configured to generate high-speed fluid may include an air pump 431 and a steam generator 432. The air pump 431 can draw in air, compress the air, and then eject the compressed air at high speed, providing a high-speed airflow to the jet channel 4513 through the second supply channel 4531. The steam generator 432 can draw in water and heat the water to form steam. The steam is ejected at high speed through the outlet of the steam generator 432, providing a high-speed airflow to the jet channel 4513 through the second supply channel 4531. The steam flows rapidly within the jet channel 4513. Due to its high speed and high temperature, a negative pressure environment is created within the jet channel 4513, which drives the liquid in the liquid storage box 41 into the jet channel 4513 through the second supply channel 4531. Within the jet channel 4513, the high-speed flowing steam and the low-speed flowing liquid are thoroughly mixed and interact. The energy and velocity of the steam cause the liquid to be rapidly atomized, forming uniform and tiny droplets. These tiny droplets, carried by the steam, are sprayed together into the garment treatment drum 10 to treat the garments.

[0097] When the power unit 43 includes a steam generator 432, the piping assembly 42 also includes a third flow path 423. The third flow path 423 connects the water storage chamber 411 and the steam generator 432, and is configured to provide a water source to the steam generator 432 to ensure sufficient water supply during the operation of the steam generator 432. Since the third flow path 423 connects to the water storage chamber 411, there is no need to install a separate liquid storage device to provide a water source to the steam generator 432, reducing the space required.

[0098] Referring to Figures 7 and 8, in some embodiments, the dispensing device 45 includes a main body 451, a first connector 452, and a second connector 453. The main body 451 has a jet channel 4513, which forms a Venturi channel with a jet nozzle. The first connector 452 is connected to the main body 451 and a third flow path 423, and has a first supply channel 4521 communicating with the Venturi channel. The second connector 453 is connected to the main body 451 and a confluence section 4212, and has a second supply channel 4531 communicating with the Venturi channel. The main body 451 facilitates the formation of the Venturi channel, wherein the Venturi channel has a throat section 4514 in the middle of the flow channel with a small diameter, which increases the velocity and decreases the pressure of the fluid as it passes through, thereby generating suction. The first connector 452 facilitates the formation of the first supply channel 4521, and the second connector 453 facilitates the formation of the second supply channel 4531. Furthermore, the first connector 452 and the second connector 453 facilitate the connection of pipelines.

[0099] Referring to Figures 7 and 8, the main body 451 further includes a valve housing 4511 and a valve core 4512. The valve housing 4511 has a mounting cavity, wherein the valve housing 4511 is connected to a first connector 452 and a second connector 453, so that the first supply channel 4521 and the second supply channel 4531 communicate with the mounting cavity. The valve core 4512 is installed in the mounting cavity and has a Venturi channel, which communicates with the first supply channel 4521. The valve core 4512 is provided with a suction channel 4515 that communicates with the second supply channel 4531 and the Venturi channel. The ratio of the diameter of the throat section 4514 to the outlet diameter of the suction channel 4515 is not greater than 1 and not less than 3. When the ratio of the diameter of the throat segment 4514 to the outlet diameter of the suction channel 4515 is smaller than 1:1, the Venturi effect is stronger, resulting in greater suction and a larger flow rate. Conversely, a larger ratio results in a weaker Venturi effect, weaker suction, and a smaller flow rate. However, a smaller ratio is not always better. If the ratio is greater than 1:1, the Venturi effect is weaker, which can lead to a lower flow rate of liquid in the reservoir 41. Conversely, if the ratio is less than 3:1, the outlet diameter of the suction channel 4515 will be smaller, also affecting the flow rate of liquid in the reservoir 41. The ratio of the diameter of the throat segment 4514 to the outlet diameter of the suction channel 4515 provided in this application is in the range of 1:1 to 3:1. Within this range, the Venturi effect is strong enough to generate sufficient suction without limiting the flow rate due to an excessively small diameter of the suction channel 4515.

[0100] The garment processing equipment 1 includes a controller, which is connected to the on / off control element 44 and the power unit 43 by signal, and is used to control the on / off state of the on / off control element 44 and the working state of the power unit 43.

[0101] The garment handling equipment 1 also includes a flow meter, which is signal-connected to the controller and configured to detect the current flow rate of the care agent dispensed by the dispensing system 40 and the current flow rate of the water dispensed by the dispensing system 40. The controller is configured to, based on the result that the current care agent flow rate reaches the target care agent dispensing amount, control the care agent chamber 412 to disconnect from the dispensing device 45 via the on / off control element 44; and based on the result that the current water flow rate is greater than the target water dispensing amount, control the water storage chamber 411 to disconnect from the dispensing device 45. In this example, based on the feedback from the flow meter, the controller can ensure that the care agent and water dispensing amounts are according to preset values. After the care agent dispensing amount reaches the target, the dispensing of care agent stops and the dispensing of water begins. After the water dispensing amount reaches the target, the dispensing of water stops, thereby achieving precise dispensing of care agent and water.

[0102] It should be noted that the order of adding the care agent and water in this application can be as follows: after the amount of care agent added reaches the target level, the addition of care agent is stopped and water is added; after the amount of water added reaches the target level, the addition of water is stopped. Alternatively, the care agent can be added first, and when the amount of care agent added reaches the preset level, the addition of care agent is stopped and water is added; when the amount of water added reaches the preset level, the addition of water is stopped and then the addition of care agent is started again, until the amounts of both care agent and water are reached. In other words, the care agent and water can be added sequentially according to the target amount, or they can be added alternately until the target amount is reached.

[0103] The garment processing equipment 1 also includes a timer, which is signal-connected to the controller and configured to detect the duration of the care agent dispensing by the dispensing system 40 and the duration of the water dispensing by the dispensing system 40. The controller is configured to, based on the result that the care agent dispensing time reaches the target dispensing time, control the dispensing chamber 412 to disconnect from the dispensing device 45 via the on / off control element 44, and control the water storage chamber 411 to connect to the dispensing device 45; based on the result that the water dispensing time exceeds the target water dispensing time, control the water storage chamber 411 to disconnect from the dispensing device 45, and control the power unit 43 to shut down. It can be understood that the instantaneous flow rate of the care agent or water dispensed by the dispensing device 45 is a fixed value. Based on this, the target care agent dispensing amount, the target water dispensing amount, and the instantaneous flow rate can be used to obtain the target care agent dispensing time and the water dispensing time. When the time detected by the timer meets the target care agent dispensing time and the water dispensing time, it will be fed back to the controller, thereby controlling the on / off control element 44 to adjust the mixing ratio of the dispensed care agent and water.

[0104] This application embodiment also provides a control method for a garment processing device, which is the garment processing device described above. Please refer to Figure 9. The control method includes the following steps:

[0105] S101, when the clothing processing equipment enters the clothing processing program, the target amount of water and the target amount of care agent are obtained;

[0106] In one embodiment, the garment processing program may include a drying program and a care program. When the user selects the drying program, the garment processing device dries the garments. When the user selects the care program, the garment processing device performs the care program and obtains the target water dosage and the target care agent dosage. The target water dosage and the target care agent dosage can be set by the user or preset by the garment processing program.

[0107] S102, based on the target water dosage and the target dosage of the care agent, control the operation of the power unit, and control the on / off state of the care agent chamber and the dispensing device through the on / off control component, as well as control the on / off state of the water storage chamber and the dispensing device.

[0108] Specifically, after the garment processing equipment obtains the target water dosage and the target dosage of the care solution, the controller controls the power unit to operate. The power unit generates power to draw water or care solution. The controller controls the on / off control components, which control the on / off states of the care solution chamber and the dispensing device, as well as the water storage chamber and the dispensing device, to control the liquid drawn by the power unit. This ensures that the amount of water dispensed by the dispensing device meets the target water dosage, and the amount of care solution dispensed by the dispensing device meets the target care solution dosage, thereby adjusting the mixing ratio of the dispensed care solution and water.

[0109] Please refer to Figure 10. The method of this application embodiment may include the following steps S201-S204.

[0110] S201. Obtain the set total dosage of care agent and water, and the set target mixing ratio of care agent and water;

[0111] For example, let T be the total amount of care product and water to be added, and R be the target mixing ratio of care product and water. R is the ratio of care product (denoted as a) to water (denoted as b), i.e., R = a:b. For example, R = 1:3 means that the ratio of care product to water is 1 part care product to 3 parts water.

[0112] S202. Obtain the target dosage of water and the target dosage of the care agent based on the total dosage and the mixing ratio of the care agent to the target dosage;

[0113] The target dosage of the nursing agent (denoted as P) can be calculated using the following formula:

[0114] P = a / (a+b) × T

[0115] The target water delivery volume (denoted as W) can be calculated using the following formula:

[0116] W = b / (a+b) × T

[0117] The target dosage of the output care agent, P, and the target dosage of water, W;

[0118] S203, Obtain the current flow rate of the nursing agent;

[0119] One method is to use a flow meter to obtain the total flow rate of the care agent being dispensed. A flow meter is an instrument configured to measure the flow rate or velocity of a fluid, and can cumulatively calculate the total flow rate of the care agent being dispensed. Optionally, the flow meter can be an electromagnetic flow meter, a vortex flow meter, a mass flow meter, an ultrasonic flow meter, or other similar types.

[0120] S204. Based on the result that the current flow rate of the care agent reaches the target amount of care agent, the care agent chamber is disconnected from the dispensing device by the on / off control component, and the water storage chamber is connected to the dispensing device.

[0121] Based on the fact that the current flow rate of the care agent meets the target dosage of the care agent, the controller controls the on / off control to disconnect the care agent chamber from the dispensing device, stopping the dispensing of the care solution. The controller also controls the on / off control to connect the water storage chamber to the dispensing device, starting the dispensing of water.

[0122] S205. Obtain the current water flow rate;

[0123] The reference for obtaining the current water flow rate is set to the format for obtaining the current care agent flow rate;

[0124] S206. Based on the result that the current water flow rate is greater than the target water delivery amount, control the water storage chamber to disconnect from the delivery device, and control the power device to shut down;

[0125] Based on the fact that the current water flow rate meets the target water delivery amount, the controller controls the on / off control component to disconnect the water storage chamber from the delivery device, stop water delivery, and control the power unit to shut down.

[0126] Please refer to Figure 11. The method of this application embodiment may include the following steps S301-S307.

[0127] S301. Obtain the set total dosage of care agent and water, and the set target mixing ratio of care agent and water;

[0128] For example, let T be the total amount of care product and water to be added, and R be the target mixing ratio of care product and water. R is the ratio of care product (denoted as a) to water (denoted as b), i.e., R = a:b. For example, R = 1:3 means that the ratio of care product to water is 1 part care product to 3 parts water.

[0129] S302. Obtain the target dosage of water and the target dosage of the care agent based on the total dosage and the mixing ratio of the care agent to the target dosage;

[0130] The target dosage of the nursing agent (denoted as P) can be calculated using the following formula:

[0131] P = a / (a+b) × T

[0132] The target water delivery volume (denoted as W) can be calculated using the following formula:

[0133] W = b / (a+b) × T

[0134] The target dosage of the output care agent, P, and the target dosage of water, W;

[0135] S303. Obtain the target dosage of the care agent and the target dosage of the water according to the target dosage of the care agent;

[0136] The instantaneous flow rate of the dispensing device when dispensing care products or water is a fixed value. Based on this, the target dispensing time of care products and the target dispensing time of water can be obtained by using the target dispensing amount of care products, the target dispensing amount of water, and the instantaneous flow rate. When the time detected by the timer meets the target dispensing time of care products and the target dispensing time of water, it will be fed back to the controller, thereby controlling the on / off control element to adjust the mixing ratio of the dispensing care products and water.

[0137] For example, the program pre-sets the instantaneous flow rate Q of the care solution dispenser. p and instantaneous water flow rate Q w The target dosage of the nursing agent, P, and the target dosage of water, obtained from the previous steps, are used to calculate the target dosage time, T, of the nursing agent. p and target delivery duration T w ;

[0138] Target delivery time T for nursing agents p =P / Q p ;

[0139] Water target deployment time T w =W / Q w；

[0140] S304. Obtain the duration of care agent administration;

[0141] The duration of the care product dispensing process is recorded by a timer.

[0142] S305. Based on the result that the care agent dispensing time has reached the target dispensing time, the care agent chamber is disconnected from the dispensing device by the on / off control component, and the water storage chamber is connected to the dispensing device.

[0143] Based on the fact that the dispensing time of the care agent meets the target dispensing time, the controller controls the on / off control to disconnect the care agent chamber from the dispensing device, stopping the dispensing of care solution. The controller also controls the on / off control to connect the water storage chamber to the dispensing device, starting the dispensing of water.

[0144] S306. Obtain the water delivery duration;

[0145] The reference for obtaining the current water flow rate is set to the format for obtaining the current care agent flow rate;

[0146] S307. Based on the result that the water delivery time is greater than the water target delivery time, control the water storage chamber to disconnect from the delivery device and control the power device to shut down;

[0147] Based on the fact that the current water flow rate meets the target water delivery amount, the controller controls the on / off control component to disconnect the water storage chamber from the delivery device, stop water delivery, and control the power unit to shut down.

[0148] This specification also provides a storage medium storing a computer program. When the computer program is executed by a processor, it implements the method shown in the embodiments of Figures 9-11 above. For the specific execution process, please refer to the detailed description of the embodiments shown in Figures 9-11, which will not be repeated here.

[0149] In this embodiment of the application, by obtaining the target amount of water and the target amount of care agent, the power device is controlled to work, and the on / off state of the on / off control component is controlled, thereby adjusting the mixing ratio of the care agent and water to meet different care needs.
