Description

Technical Field

[0001] This application relates to the field of liquid cleaning product technology, and in particular to a liquid dispensing device and its usage method. Background Technology

[0002] Most liquid cleaning products are manual, such as pump dispensers, flip-top caps, measuring cup caps, and dispensing caps. These products are either inconvenient or cumbersome to use, and opening the bottle exposes the liquid to the external environment, easily leading to contamination and cross-contamination of bacteria. Furthermore, pump dispensers often require excessive pressure, and measuring cup caps and dispensing caps are prone to getting dirty, all of which severely impact the user experience.

[0003] While automatic liquid dispensing pumps can solve many of the above problems, the need for charging when the power is off or repair due to quality issues can negatively impact the user experience. When an electric liquid dispensing pump is charging or under repair, it is unusable. During this time, if cleaning fluid is needed, users must either purchase a temporary replacement or delay the cleaning process. This not only causes significant inconvenience but may also incur unnecessary expenses.

[0004] In addition, as user scenarios and needs become more diversified and personalized, a single distribution method cannot meet the differentiated needs of more users. For example, producing products specifically for each segment of the population would increase manufacturing costs. Summary of the Invention

[0042] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0043] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0044] In the description of this application, "several" means one or more, "more than" means at least two, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0045] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this application after considering the specific content of the technical solution.

[0046] Reference Figures 1 to 9 The liquid dispensing device of the first aspect of this application is mainly used for other liquid cleaning products such as dishwashing liquid, hand soap, and laundry detergent. The liquid dispensing device includes a bottle body 100, an automatic pump component 200, and a replacement pump component.

[0047] The automatic pump component 200 is integrated and detachably connected to the bottle body 100. A replacement pump component is also integrated and detachably connected to the bottle body 100. In use, one of the automatic pump component 200 or the replacement pump component is connected to the bottle body 100. By designing the automatic pump component 200 and the replacement pump component as an integrated structure, the two can be freely switched, and one can be installed on the bottle body 100 for normal use of the dispensing device. This also allows the replacement pump component to be interchangeable and switched when the automatic pump component 200 needs to be disassembled, repaired, or recharged, providing users with multiple options and backup solutions.

[0048] In some embodiments, this novel platform-based, interoperable liquid dispensing system allows for the interchangeability of manual and automatic dispensing pumps, providing users with multiple options. When the automatic pump component 200 runs out of power and needs charging, or when the automatic dispensing device malfunctions, a quick switch to a manual pump can be implemented as a backup. This convenient and practical system meets the diverse usage needs of users in various scenarios.

[0049] In some embodiments, the replacement pump component is an automatic pump component 200 or a manual pump component 300. It is understood that after removing the automatic pump component 200 that needs to be replaced, either the manual pump component 300 or another automatic pump component 200 can be installed on the bottle body 100. This satisfies backup needs without affecting the user experience, thus providing users with multiple options and backup solutions through compatibility, sharing, and switching.

[0050] Understandably, as users become more environmentally conscious and sustainable, they will consider and accept more environmentally friendly and cost-effective refill packs for liquid cleaning products after the liquid has run out. However, conventional liquid cleaning products can be used directly by opening the cap or unscrewing the pump head for refilling, which can easily lead to liquid contamination inside the bottle, posing certain hygiene and safety issues. Furthermore, when using a refill pack, the pump needs to be removed from the empty bottle and inserted into the pack; since the pump core and its tubing may come into contact with liquid, the liquid on them can slip or drip due to gravity, easily soiling hands and the floor, affecting the user experience. Therefore, users need a safer and cleaner product that provides a non-stick, drip-free refill method and solves the problems of cumbersome refilling, sticking, and dripping.

[0051] In some embodiments of this application, the dispensing device further includes a pump sleeve 400 and a first check valve 410. The pump sleeve 400 is disposed at the bottle opening 110 of the bottle body 100 and extends into the interior of the bottle body 100. The pump sleeve 400 has a receiving cavity for accommodating the automatic pump component 200 or a replacement pump component, and a liquid inlet 440 is provided at one end of the pump sleeve 400 relatively away from the bottle opening 110. The liquid inlet 440 communicates with the receiving cavity. The first check valve 410 is disposed between the liquid inlet 440 and the receiving cavity and is capable of unidirectional flow in the direction from the liquid inlet 440 to the bottle opening 110. It can be understood that the main function of the pump sleeve 400 is to prevent the automatic pump component 200 and the manual pump component 300 from being immersed in liquid and causing liquid contamination. The design of the embedded fixed pump sleeve 400 enables the replacement and replenishment of liquids without immersing the pump in liquid, whether it is a manual or automatic pump. Liquid can be drawn through the pump sleeve 400, thus achieving liquid replacement and replenishment without getting the pump wet. This makes the operation more hygienic, quick and convenient.

[0052] In some embodiments, the pump sleeve 400 has a guide portion at the end relatively far from the bottle opening 110, which gradually narrows along the direction from the bottle opening 110 to the liquid inlet 440. The liquid inlet 440 is located at the relatively smallest end of the guide portion, and the relatively largest end of the guide portion communicates with the receiving cavity. A first check valve 410 is located inside the guide portion. It can be understood that the main function of the pump sleeve 400 is to isolate the pump component from the liquid inside the container, preventing the pump component from being immersed in the liquid and thus avoiding liquid contamination. To this end, the design of the liquid inlet 440 of the pump sleeve 400 allows the pump component to smoothly contact the liquid inside the container. Furthermore, by specifically designing the structure of the liquid inlet 440, liquid contamination and leakage are further avoided, thereby further improving the user experience.

[0053] In some embodiments, the relatively large end of the guide section is used for an interference-sealed connection with the inlet pipe 420 of the pump component, so that the liquid can flow smoothly. The relatively small end of the guide section is used to set a liquid pipe that extends into the liquid surface of the container, and a first check valve 410 is set between the two ends of the guide section, so as to ensure that the check valve 410 has a better backflow prevention effect.

[0054] In some embodiments of this application, the pump sleeve 400 is attached to the bottle opening 110 via a snap-fit ​​connection. It is understood that the one-way pump sleeve 400 engages with the packaging bottle through a snap-fit ​​and stop-point positioning method. The outer side of the one-way pump sleeve 400 is press-fitted against the inner side of the bottle opening 110 by a sealing ring, while the inner side is sealed by a one-way valve, thus ensuring a good seal so that the pump components can still function normally after the pump sleeve 400 is installed.

[0055] In some embodiments of this application, the pump component has a positioning groove on its inner side, and the pump sleeve 400 has a positioning stop and an anti-rotation stop. When the pump component is connected to the pump sleeve 400 and installed to a preset position, it abuts against the positioning stop, and the anti-rotation stop is embedded in the positioning groove. It is understood that the pump component has a threaded structure on its inner side, with protrusions spaced at the ends of the threaded structure. When the pump component is rotated and installed to a suitable position on the pump sleeve 400 via the threaded structure, the protrusions abut against the positioning stop, indicating that it is installed in place. Simultaneously, the anti-rotation stop is also set in the positioning groove when installed in place. Through the cooperation of the anti-rotation stop and the positioning groove, the pump component cannot be dislodged in the opposite direction, achieving the anti-rotation effect.

[0056] In some embodiments of this application, at least one of the automatic pump component 200 or the replacement pump component includes an inlet pipe 420 and a second check valve 430. The inlet pipe 420 is press-fitted to the inlet port 440, and the second check valve 430 is disposed within the inlet pipe 420 and is capable of unidirectional flow from the inlet port 440 to the bottle neck 110. It is understood that the bottom check valve design prevents liquid adhering to the internal channels of the dispensing device from slipping or dripping during replacement and replenishment, ensuring that no dripping occurs during replacement and replenishment or when switching between manual and automatic pumps, making the operation more hygienic and clean.

[0057] Meanwhile, the second check valve 430 can also be used to solve the problem of stable pumping output in automatic liquid dispensing devices. It is understandable that, after a conventional automatic liquid dispensing device has taken liquid, if it is not operated frequently and continuously, when it is taken again after a period of time, it will be found that the automatic liquid dispensing device experiences dry pumping or initially pumps out less liquid. The root cause of this unstable pumping output is that the liquid in the pipeline is affected by gravity and flows back downwards, resulting in a cavity in the first half of the dispensing pipe. To solve this problem, a check valve can be added to the liquid channel. This way, even under infrequent use, dry pumping or significantly insufficient liquid output will not occur, better ensuring the stability and consistency of the pumped liquid output.

[0058] In some embodiments of this application, the replacement pump component is a manual pump component 300. The manual pump component 300 includes a first mounting portion 310, a push-button assembly 320, a piston column assembly 330, a spring element 340, and a body assembly 350. The body assembly 350 includes a cavity and is disposed on the first mounting portion 310 for embedding into the bottle body 100. One end of the piston column assembly 330 and the spring element 340 are disposed within the cavity of the body assembly 350, and the other end of the piston column assembly 330 passes through the first mounting portion 310 and connects to the push-button assembly 320. It is understood that by integrating the functions of the components and designing the vertical arrangement of the components, the distance between the components is compressed to a more compact size, leaving no unnecessary space. This reduces material usage, results in a simpler appearance, and improves product molding quality, thereby reducing the manufacturing cost of the device. This addresses / improves the problems of large volume, large exposed volume, high exposed height, large footprint, and high manufacturing cost of the liquid dispensing device.

[0059] In some embodiments, the first mounting part 310 includes a cover and a locking cap disposed on the cover. The push-button assembly 320 is threadedly connected to the locking cap after assembly or during transportation to prevent leakage. When in use, the push-button assembly 320 is unscrewed from the locking cap, and the push-button assembly 330, in conjunction with the elastic element 340 and the piston column assembly 330, allows for repeated pressing and multiple dispensing of liquid. The elastic element 340 may be a spring, and the piston column assembly 330 includes a main column, a secondary column, a piston, and a glass ball arranged sequentially.

[0060] In some embodiments, the automatic pump component 200 or the manual pump component 300 is installed on the pump sleeve 400 or the bottle neck 110 by the same detachable connection. When the pump sleeve 400 is used, the pump sleeve 400 is also detachably connected to the bottle neck 110. The detachable connection includes, but is not limited to, threaded connection or snap-fit ​​connection. The connection between adjacent components must be properly sealed and have a return air channel to allow the liquid to flow smoothly.

[0061] In some embodiments of this application, the automatic pump component 200 includes a second mounting portion 210, a body 220, and an electric component 230. The body 220 includes a first mounting cavity 221, which is disposed on the second mounting portion 210 and used to embed within the bottle body 100. At least a portion of the electric component 230 is disposed within the first mounting cavity 221, such that when the second mounting portion 210 is installed at the bottle neck 110 of the bottle body 100, at least a portion of the electric component 230 is located within the bottle body 100. It is understood that the embedded automatic dispensing device can solve / improve problems such as excessive exposed height, excessive exposed volume, and large footprint of the dispensing device. By designing a body 220 component that can be embedded in the container and integrating the electric component 230, at least a portion of the electric component 230 can be accommodated in the first mounting cavity 221. After the second mounting part 210 is installed at the container opening, at least a portion of the electric component 230 can be embedded in the container, thereby reducing the exposed height and volume, making the structure more compact, and reducing the product cost to a certain extent.

[0062] In some embodiments, the second mounting portion 210 includes a mounting end for mounting, and the body 220 is disposed on the second mounting portion 210 and used for embedding within the container. The body 220 includes a first mounting cavity 221 extending from the mounting end in a direction away from the mounting end. It is understood that the embedded design of the automatic dispensing device components can solve / improve problems such as excessive exposed height, excessive exposed volume, and large footprint of the dispensing device. By embedding its components within the packaging bottle, the volume of the automatic dispensing device exposed outside the bottle becomes more compact, while also reducing the exposed height of the automatic dispensing device. The embedded design can involve all components being embedded within the packaging bottle, such as the automatic pump component 200 having all components except the outlet embedded within the packaging bottle, such as the battery and pump motor. Alternatively, it can involve partial embedding within the packaging bottle, such as having other components besides the outlet of the automatic pump component 200 not embedded within the packaging bottle.

[0063] In some embodiments of this application, the second mounting portion 210 forms a second mounting cavity 211, which communicates with the first mounting cavity 221. The electric component 230 includes a control component 231, a drive component 232, and a battery component 233. The control component 231, drive component 232, and battery component 233 are arranged along the axial direction of the second mounting portion 210 and are electrically connected. The control component 231 is disposed in the second mounting cavity 211, the battery component 233 is disposed in the first mounting cavity 221, and the drive component 232 is located between the control component 231 and the battery component 233. It is understood that by arranging the first mounting cavity 221 and the second mounting cavity 211 adjacent to and communicating with each other, the distance between components is designed to be more compact, and the components and their functions are more integrated. This makes the product more compact and lightweight, while also making the appearance simpler and improving molding quality. The reduction in material usage and the decrease in the proportion of defective products also mean a reduction in cost.

[0064] In some embodiments, when all electric components 230 are housed within the second mounting cavity 211, the distance between components can be designed to be more compact, and the components and their functions can be more integrated, resulting in a smaller and lighter product. In this case, other corresponding components can be strategically arranged inside the second mounting portion 210, or the design of the first mounting cavity 221 of the second mounting portion 210 can be eliminated to meet different usage requirements. It is understood that the embedded design reduces the volume of the automatic dispensing device while also saving space for the automatic pump component 200. Furthermore, by compressing the component size as much as possible, that is, embedding the automatic pump component 200 as much as possible within the packaging bottle space, the volume of the automatic pump component 200 protruding from the bottle is controlled. The visual reduction in the size of the automatic dispensing device further reduces its overall volume. The integrated design allows for a more compact distance between components and a more integrated function, resulting in a smaller and lighter product with a simpler appearance and improved molding quality. Reducing the amount of materials used and lowering the proportion of defective products both mean lower costs.

[0065] Understandably, the control component 231 is located in the second mounting cavity 211, the battery component 233 is located in the first mounting cavity 221, and the drive component 232 is located between the control component 231 and the battery component 233. The vertical arrangement of the components reduces the diameter of the automatic dispensing device, thereby reducing its footprint. The embedded design of the automatic dispensing device components, by embedding them inside the packaging bottle, makes the volume of the automatic dispensing device exposed outside the bottle more compact, while also reducing the exposed height of the automatic dispensing device.

[0066] In some embodiments, the order in which the control component 231, drive component 232, and battery component 233 are arranged axially can be adaptively adjusted to meet different needs and scenarios.

[0067] In some embodiments, the one-way pump sleeve 400 is engaged with the packaging bottle via a snap-fit ​​and stop positioning mechanism; the outer side of the one-way pump sleeve 400 is interference-sealed inside the bottle opening 110 by a sealing ring, and the inner side is sealed by a one-way valve. The automatic pump component 200 is engaged with the one-way pump sleeve 400 via a thread and positioning mechanism; the automatic pump component 200 is interference-sealed with the one-way pump sleeve 400 via the bottom of its base, primarily to prevent liquid leakage into the one-way pump sleeve 400 after the one-way valve is opened. The manual dispensing device is engaged with the one-way pump sleeve 400 via a thread and positioning mechanism.

[0068] In some embodiments, the manual pump component 300 is press-fitted to the one-way pump sleeve 400 through the bottom of the body or the bottom of the suction pipe, mainly to prevent liquid from leaking into the one-way pump sleeve 400 after the one-way valve is opened; it is also sealed to the top of the pump sleeve 400 through a gasket, providing double leak prevention.

[0069] In some embodiments, the refill cap 120 and the one-way pump sleeve 400 are fitted together by threads and positioning; the refill cap 120 is sealed to the inside of the one-way pump sleeve 400 by a single-ring sealing ring, while preventing liquid from entering through the vent hole.

[0070] In some embodiments, the automatic dispensing device and the packaging bottle are fitted together via threads and positioning; the automatic pump component 200 is interference-sealed with the bottle neck 110 via a gasket at the top of the thread. The manual pump component 300 is fitted together with the packaging bottle via threads and positioning.

[0071] In some embodiments, the manual pump component 300 is interference-sealed with the bottle neck 110 via a gasket at the top of the thread. The refill cap 120 is fitted to the packaging bottle via a threaded and positioning mechanism.

[0072] In some embodiments, the refill cap 120 is press-fitted to the inside of the bottle opening 110 by a single-ring sealing ring.

[0073] In some embodiments, when the automatic liquid dispensing device + one-way pump sleeve 400 + packaging bottle is used, the liquid pumped out by the automatic pump component 200 mainly involves the liquid in the bottle passing through the suction tube and one-way valve of the pump sleeve 400, then entering the inlet seat from the bottom of the automatic liquid dispensing device, then entering the pump through the liquid pipe, and then being pumped out through the liquid outlet head and the one-way valve. The return of gas in the bottle mainly involves external air entering through the threaded connection between the automatic liquid dispensing device and the one-way pump sleeve 400, then passing through the step at the mating position between the one-way pump sleeve 400 and the top surface of the bottle mouth 110 (the mating position between the one-way pump sleeve 400 and the top surface of the bottle mouth 110 is designed with a small rib around the circumference, mainly to ensure that an air passage is formed between the pump body and the pump sleeve 400), then entering the interior of the one-way pump sleeve 400 through the gap of the reinforcing ribs on the inner side of the one-way pump sleeve 400, and then returning to the bottle through the return air hole on the inner side of the one-way pump sleeve 400 to replenish the gas, thereby realizing the pumping out of the liquid.

[0074] In some embodiments, when a manual dispensing device is used with a one-way pump sleeve 400 and a packaging bottle, the liquid is pumped out by the manual dispensing device mainly through the suction tube and one-way valve of the pump sleeve 400, then from the bottom of the manual dispensing device body into the storage chamber. Pressing causes the liquid to enter the secondary column through the liquid hole, then through the main column, and finally through the dispensing channel of the pusher head for pumping out. The return of gas from the bottle mainly involves external air entering the body through the gap between the main column and the locking cap component of the manual dispensing device, then entering the one-way pump sleeve 400 through the return air hole on the inner circumference of the body, and then returning to the bottle through the return air hole on the inner side of the one-way pump sleeve 400 to replenish the gas, thus achieving the pumping out of the liquid.

[0075] In some embodiments, when the automatic liquid dispensing device is combined with a packaging bottle (without the pump sleeve 400 structure), the liquid is pumped out by the automatic liquid dispensing device mainly through the suction tube at the bottom of the device, then through the check valve, into the inlet seat, then through the liquid pipe into the pump, then out through the liquid pipe, and finally pumped out through the outlet head and the one-way valve. The return of gas from the bottle is mainly achieved by external air entering through the threaded connection between the automatic liquid dispensing device and the packaging bottle, then passing through the step at the interface between the automatic liquid dispensing device and the top surface of the bottle opening 110 (the interface between the one-way pump sleeve 400 and the top surface of the bottle opening 110 is designed with a circumferential rib to ensure an air passage is formed between the pump body and the pump sleeve 400) to replenish the gas in the bottle, thus achieving the pumping out of the liquid.

[0076] In some embodiments, when the manual dispensing device is used with a packaging bottle (400 structure without pump sleeve), the liquid is pumped out by the manual dispensing device mainly through the suction tube and one-way valve, then from the bottom of the device body into the storage chamber. Pressing causes the liquid to enter the secondary column through the liquid hole, then through the main column, and finally through the dispensing channel of the pusher head. Gas return from the bottle mainly involves external air entering the device body through the gap between the main column and the locking cap component, then entering the packaging bottle through the circumferential vent hole to replenish the air and achieve liquid pumping.

[0077] In some embodiments of this application, the automatic pump component 200 includes a liquid inlet assembly 240, and the second mounting portion 210 includes an outwardly extending liquid outlet arm 212 with an outlet nozzle 250. An electric component 230 enables the outlet nozzle 250 to output liquid. The liquid inlet assembly 240 is disposed within the first mounting cavity 221 and serves to support the battery assembly 233. The liquid inlet assembly 240 connects the interior of the bottle 100, the drive component 232, and the outlet nozzle 250 via a liquid pipe. It is understood that the liquid inlet assembly 240 reliably supports the battery assembly 233 while limiting the installation position of the liquid pipe, ensuring a reasonable overall layout within the body 220.

[0078] In some embodiments, a first liquid pipe and a second liquid pipe are included. A liquid inlet 440 is provided on the body 220. One end of the first liquid pipe is connected to the output nozzle 250, and one end of the second liquid pipe is connected to the liquid inlet 440. The other ends of the second liquid pipe and the first liquid pipe are respectively connected to the drive assembly 232. It is understood that the first and second liquid pipes enable the liquid to be transported by the drive assembly 2320 to the output nozzle 250. By placing the first liquid pipe between the cavity inside the liquid outlet arm 212 and the second mounting cavity 211, and placing the first liquid pipe within the first mounting cavity 221, a further integrated arrangement is achieved. The liquid inlet end is connected to the liquid inlet 440, and the liquid outlet end is connected to the first liquid pipe. The liquid inlet end and the liquid outlet end are connected and spaced apart on one side of the mounting position.

[0079] In some embodiments of this application, the automatic pump component 200 includes a sensing component 260, which is disposed on the dispensing arm 212 and relatively close to the dispensing nozzle 250. The sensing component 260 is electrically connected to the control component 231. After the automatic pump component 200 is installed at the bottle opening 110 of the bottle body 100, it can be rotated and adjusted around the circumference of the bottle body 100 to make the circumferential position of the dispensing nozzle 250 adjustable. It is understood that the ability of the automatic pump component 200 to be rotated and adjusted around the circumference of the bottle body 100 after being installed at the bottle opening 110 can be used to solve the problem of false sensing in automatic dispensing devices and improve the user experience.

[0080] Understandably, the root cause of false sensing in automatic liquid dispensing devices, besides potential device malfunction, lies in the fact that the dispensing window typically extends forward to provide sufficient space for the hand to dispense liquid. Since the liquid sensor itself has a certain distance, when the window extends too far forward, users are more likely to move closer to the window while washing / rinsing dishes or washing their hands, increasing the likelihood of false dispensing. Furthermore, a larger sensor area further increases the probability of false sensing. However, since the dispensing window of an automatic liquid dispensing device is primarily designed to better accommodate the user's hand size and facilitate liquid dispensing, simply shortening the window's extension would be contradictory. Therefore, this solution provides multiple operable dispensing directions after the dispensing device is properly engaged with the pump sleeve 400, instead of a single forward direction. When frequent false sensing occurs or when frequent dispensing is not involved, the dispensing window can be rotated to the left or right, effectively preventing false sensing.

[0081] In some embodiments, the automatic pump component 200 and the pump sleeve 400 are designed with four positioning threads, so that the liquid dispensing device has four operable liquid dispensing directions after it is properly engaged with the pump sleeve 400, instead of a single forward direction, thereby effectively avoiding the problem of false sensing.

[0082] In some embodiments, when the overall appearance of the product is flat and elongated, if the dispensing device only has a single forward direction, it will affect the appearance when placed on the offline sales shelf. However, when the dispensing device has a left-right direction, it can better complement the flat and elongated bottle and better showcase its appearance.

[0083] In some embodiments, the second mounting portion 210 includes an outwardly extending dispensing arm 212 with an outlet nozzle 250. An electric component 230 enables the outlet nozzle 250 to dispense liquid. The dispensing arm 212 is used to maintain a certain distance between the outlet nozzle 250 and the bottle body for ease of use. The outlet nozzle 250 is positioned appropriately on the dispensing arm 212, and dispensing is achieved under the control of the electric component 230. Alternatively, the electric component 230, in conjunction with the sensing component 260, can achieve automatic dispensing, further enhancing ease of use. When the sensing component 260 detects a preset detection object near the outlet nozzle 250, it sends a signal to the control component 231, which then triggers the drive component 232 to dispensing liquid from the outlet nozzle 250.

[0084] In some embodiments, the liquid dispensing arm 212 has a cavity communicating with the second mounting cavity 211. This cavity is used to install a liquid pipe so that the output nozzle 250 can dispense liquid normally, and also to reserve space for electrical connection. Thus, the electric components 230 are arranged in at least one of the first mounting cavity 221 or the second mounting cavity 211, thereby making the overall layout reasonable.

[0085] In some embodiments of this application, the outlet nozzle 250 is provided with a one-way shut-off valve 270 in the output direction; it is understood that the shut-off valve 270 is used to solve the problems of liquid residue and weathering / drying at the outlet nozzle of the automatic liquid dispensing device. In some embodiments, the shut-off valve 270 is a one-way silicone shut-off valve 270. In other embodiments, shut-off valves 270 with other structural forms can be used to meet different usage requirements.

[0086] It is understandable that conventional automatic dispensing devices will leave some liquid residue at the nozzle after dispensing liquid, which is what we call "liquid residue at the dispensing nozzle." This liquid residue can be caused by, but is not limited to, the following: ① Insufficient cutting force of the dispensing nozzle on the liquid contents, resulting in insufficient liquid cutting and thus liquid residue at the nozzle; ② The viscosity of the liquid contents is too high, making it difficult to cut; ③ After the liquid is pumped out, a small amount of liquid remains in the dispensing nozzle channel. When the pump stops working, the liquid in the channel flows downwards due to gravity. Since dispensing nozzles are typically designed to be vertically downwards or curved downwards, the liquid residue in the dispensing nozzle channel flows to the nozzle, creating liquid residue. If the liquid residue hanging on the automatic dispensing device is not wiped off or treated, it will accumulate over time or with infrequent use, eventually drying and forming clumps at the nozzle. Not only are there hygiene issues, but the condensed liquid may also clog the automatic dispensing device, preventing the liquid from being pumped out or damaging the device.

[0087] Therefore, to address the issue of liquid residue clinging to the nozzle of the automatic dispensing device after dispensing, a one-way silicone shut-off valve 270 is incorporated into the nozzle design. When the automatic dispensing device detects a hand touch and initiates dispensing, the valve opens due to the pressure of the liquid. After dispensing, the valve automatically closes due to the absence of liquid pressure, quickly cutting off the liquid flow and preventing residue cling to the nozzle. Furthermore, the closure of the one-way silicone shut-off valve 270 also better protects the liquid inside the nozzle and dispensing channel from drying out due to air, solving the problem of liquid weathering, drying, and clumping at the nozzle. This prevents a negative user experience from the outset.

[0088] In some embodiments of this application, the control component 231 is configured to control the drive component 232 to deliver different amounts of liquid to the output nozzle 250 for output based on the sensing distance information detected by the sensing component 260 between the approaching object and the output nozzle 250. It is understood that, to meet the usage needs of users in different scenarios, the liquid dispensing device in this embodiment does not have a completely predetermined pumping volume, but rather offers two or more different pumping volume options. The automatic liquid dispensing principle of conventional automatic liquid dispensing devices mainly relies on sensing technology and intelligent control. Automatic liquid dispensing devices typically consist of a body 220, a sensing module, a control module, a drive module, a power module, and a packaging bottle. When a user's hand approaches the sensing module, the sensing module detects the approach using infrared sensing technology and immediately sends a signal. After receiving the signal, the control module drives the motor to extract the liquid contents from the packaging bottle and then pumps it out through the dispensing nozzle. However, conventional automatic liquid dispensing devices are limited by a predetermined pumping volume, making it difficult to meet the usage needs of different groups and users in different scenarios.

[0089] To address this, this application controls the liquid dispensing volume through a sensing distance. When users need to dispense liquid at different rates based on their specific usage scenarios, they simply need to sense the distance between their hand and the dispensing window to dispense the appropriate amount. This caters to the cleaning needs of different groups, including single individuals and multi-person households. It makes the automatic dispensing device more user-friendly while preventing liquid waste. This design is not only convenient and hygienic but also accurately determines the user's actual liquid dispensing needs, effectively reducing hand contamination, improving cleaning efficiency, and avoiding liquid waste, thus aligning with current environmental sustainability requirements.

[0090] Reference Figures 1 to 9 The method of using the liquid dispensing device according to the second aspect of this application can be the method of using the liquid dispensing device according to the first aspect of this application. The method of using the liquid dispensing device includes the following steps:

[0091] The automatic pump component 200 is installed onto the bottle body 100 for use.

[0092] When it is necessary to remove the automatic pump component 200, install the replacement pump component onto the bottle body 100 for use;

[0093] When the automatic pump component 200 needs to be reused, the replacement pump component is removed and the automatic pump component 200 is reinstalled on the bottle body 100 for use.

[0094] Understandably, if the automatic dispensing device runs out of power and needs charging, or if the automatic dispensing device itself malfunctions during operation, it can be turned off, unscrewed, removed, and temporarily replaced with a push-button dispensing device. Once charging or repair is complete, the push-button dispensing device can be replaced back with the automatic dispensing device. In short, the manual and automatic dispensing devices are interchangeable.

[0095] In some embodiments, when using replacement packaging, an additional replacement step is performed:

[0096] Step 1: Twist and open the refill bottle cap 120;

[0097] Step 2: Insert the automatic or manual liquid dispensing device and tighten it in place;

[0098] Step 3: Normal liquid collection and use.

[0099] This assumes that the first use is a manual dispensing device. If the first use is an automatic dispensing device, the same principle applies; simply swap the positions of the manual and automatic dispensing devices.

[0100] In some embodiments, the replacement bottle cap 120 sealing ring of the supplementary packaging provides an interference seal to the vent hole on the one-way pump sleeve 400 to ensure that liquid enters the pump sleeve 400.

[0101] In some embodiments, regardless of whether the pump sleeve 400 is present in the bottle body 100, the manual pump component 300 and the automatic pump component 200 of both schemes can be interchanged and used interchangeably.

[0102] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
