If the first, second, etc. are described, it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of indicated technical features.

[0039] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing, connecting, etc. should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical solution.

[0040] Referring to Figures 1 to 9 The liquid outlet device of the first aspect embodiment of the present application is mainly applied to liquid cleaning products such as dishwashing liquid, hand washing liquid, laundry liquid, etc. The liquid outlet device comprises a bottle body 100, an automatic pump component 200 and a replacement pump component.

[0041] The automatic pump component 200 is integrally arranged and can be detachably connected with the bottle body 100, and the replacement pump component is integrally arranged and can be detachably connected with the bottle body 100. During use, one of the automatic pump component 200 and the replacement pump component is connected with the bottle body 100. By designing the automatic pump component 200 and the replacement pump component as an integrally arranged structure, the automatic pump component 200 and the replacement pump component can be arbitrarily switched and one of them can be installed on the bottle body 100 for normal use of the liquid outlet device, so that the replacement pump component can be mutually matched and shared and switched when the automatic pump component 200 needs to be disassembled, repaired or charged, etc., thereby providing the user with multiple choices and backup solutions.

[0042] In some embodiments, the brand-new platformized and compatible liquid dispensing system device can realize the mutual use of manual push pumps and automatic dispensing pumps, providing users with multiple choices. When the automatic pump component 200 needs to be charged or the automatic dispensing device is damaged, the manual push pump can be used as a backup through quick switching. This is convenient and practical, and meets the user's demand for multiple scenarios.

[0043] In some embodiments, the replacement pump component is an automatic pump component 200 or a manual pump component 300. It can be understood that after the automatic pump component 200 that needs to be replaced is disassembled, the manual pump component 300 or another automatic pump component 200 can be installed on the bottle body 100, so as to meet the backup demand while not affecting the user experience, thereby providing users with multiple choices and backup solutions through mutual use and switching.

[0044] It can be understood that as users' awareness of environmental protection and sustainability improves, users will also consider and accept more environmentally friendly and cost-effective replacement refills after using liquid cleaning products. However, conventional liquid cleaning products can be directly opened for use or the pump head can be unscrewed for liquid replacement and replenishment, which can easily lead to contamination of the liquid in the bottle, posing certain hygiene and safety problems. In addition, when using replacement refills, the pump needs to be removed from the empty bottle and installed in the replacement refill. However, the pump core and its liquid pipe will be contaminated with liquid, which will slide or drip due to gravity, easily staining hands and the ground, and affecting the user's experience. Therefore, users need a safer and cleaner product to provide a replacement method that does not contaminate or drip liquid and to solve the problems of liquid replacement and replenishment.

[0045] In some embodiments of the present application, the liquid dispensing device further comprises a pump sleeve 400 and a first check valve 410. The pump sleeve 400 is arranged at the bottle mouth 110 of the bottle body 100 and extends into the interior of the bottle body 100. The pump sleeve 400 has a containing cavity for containing the automatic pump component 200 or the replacement pump component. The end of the pump sleeve 400 opposite to the bottle mouth 110 is provided with a liquid inlet 440, and the liquid inlet 440 is in communication with the containing cavity. The first check valve 410 is arranged between the liquid inlet 440 and the containing cavity and can be unidirectionally conducted in the direction from the liquid inlet 440 to the bottle mouth 110. It can be understood that the main function of the pump sleeve 400 is to isolate the automatic pump component 200 and the manual pump component 300 from being soaked in liquid and contaminated. Through the design of the embedded and fixed pump sleeve 400, when replacing and replenishing, neither the manual pump nor the automatic pump needs to be soaked in liquid. Instead, the pump sleeve 400 is used to suck liquid, so that liquid can be replaced and replenished without contamination, and the operation is more hygienic, fast and convenient.

[0046] In some embodiments, the end of the pump sleeve 400 that is relatively far from the bottle mouth 110 is provided with a gradually narrowing flow guide portion in the direction from the bottle mouth 110 to the liquid inlet 440, the liquid inlet 440 is arranged at the relatively smallest end of the flow guide portion, the relatively largest end of the flow guide portion is in communication with the accommodation cavity, and the first check valve 410 is arranged in the flow guide portion. It can be understood that the main function of the pump sleeve 400 is mainly to isolate the pump component from the liquid in the container, so that the pump component is not soaked in the liquid, thereby avoiding the liquid adhesion. For this purpose, the liquid inlet 440 of the pump sleeve 400 is designed to enable the pump component to smoothly contact the liquid in the container. In addition, by designing the structure of the liquid inlet 440, the liquid adhesion and leakage are further avoided, thereby further improving the use experience.

[0047] In some embodiments, the relatively large end of the flow guide portion is used for interference sealing connection with the liquid inlet pipe 420 of the pump component, so that the liquid can flow smoothly, the relatively small end of the flow guide portion is used for arranging the liquid pipe that extends into the liquid surface of the container, and the first check valve 410 is arranged between the two ends of the flow guide portion, thereby ensuring that the check effect of the first check valve 410 is better.

[0048] In some embodiments of the present application, the pump sleeve 400 is arranged on the bottle mouth 110 by means of buckle connection. It can be understood that the one-way pump sleeve 400 is matched with the packaging bottle by means of buckle + blocking point positioning, wherein the outer side of the one-way pump sleeve 400 is interference sealed on the inner side of the bottle mouth 110 by means of a sealing ring, and the inner side is sealed by means of a one-way valve, thereby ensuring the sealing effect so that the pump component can still work normally after the pump sleeve 400 is arranged.

[0049] In some embodiments of the present application, the inner side of the pump component is provided with a positioning clamping groove, the pump sleeve 400 is provided with a positioning blocking point and an anti-rotation blocking point, and the pump component is abutted to the positioning blocking point when being connected with the pump sleeve 400 and installed to a preset position, and the anti-rotation blocking point is embedded in the positioning clamping groove. It can be understood that the inner side of the pump component is provided with a threaded structure, and a protruding portion is arranged at the end of the threaded structure, when the pump component is rotated and installed to a suitable position on the pump sleeve 400 by means of the threaded structure, the protruding portion is abutted to the positioning blocking point, which represents that the pump component has been installed to the position, and the anti-rotation blocking point is also arranged in the positioning clamping groove at the same time when being installed to the position. Through the cooperation of the anti-rotation blocking point and the positioning clamping groove, the pump component cannot be pulled out in the opposite direction, thereby achieving the effect of anti-rotation.

[0050] In some embodiments of the present application, at least one of the automatic pump component 200 or the replacement pump component includes a liquid inlet pipe 420 and a second check valve 430, the liquid inlet pipe 420 is interference sealed with the liquid inlet 440, and the second check valve 430 is arranged in the liquid inlet pipe 420 and can be unidirectionally communicated in the direction from the liquid inlet 440 to the bottle opening 110. It can be understood that through the bottom check valve design, the situation that the liquid attached in the internal channel of the dispensing device falls or drops during replacement and supplement is avoided, so that there is no dripping during replacement and supplement and manual pump / automatic pump switching, making the operation process more hygienic and clean.

[0051] At the same time, the second check valve 430 can also be used to solve the problem of stable pumping of the automatic liquid dispensing device. It can be understood that after taking liquid, the conventional automatic liquid dispensing device will be found to be empty pumping or to have less pumping liquid at the beginning when taking liquid again after a period of time without continuous frequent operation. The root cause of this unstable pumping amount is that the liquid in the pipeline flows back under the influence of gravity, resulting in a cavity in the front half of the liquid outlet pipe. To solve this problem, a check valve can be added in the liquid channel range, so that even in the case of infrequent use, there will be no empty pumping or significantly less pumping liquid, which can better ensure the stable amount and stability of liquid pumping.

[0052] In some embodiments of the present application, the replacement pump component is a manual pump component 300, which includes a first mounting part 310, a push head assembly 320, a piston column assembly 330, a spring 340, and a body assembly 350. The body assembly 350 includes a cavity, and is arranged on the first mounting part 310 for embedding in the bottle body 100. One end of the piston column assembly 330 and the spring 340 are arranged in the cavity of the body assembly 350, and the other end of the piston column assembly 330 passes through the first mounting part 310 and is connected with the push head assembly 320. It can be understood that through the integration of component functions and the vertical arrangement of components, the distance between components is compressed more compactly and neatly, without leaving too much unnecessary space, which reduces the amount of materials used, and at the same time, the appearance is more concise and more conducive to improving the molding quality of the product, thereby reducing the product cost of the device, to solve / improve the problems of large volume, large exposed volume, high exposed height, large occupation, and high product cost of the liquid dispensing device.

[0053] In some embodiments, the first mounting portion 310 comprises a cover and a locking cover arranged on the cover, and the head assembly 320 is threadedly connected to the locking cover to prevent liquid leakage after assembly or during transportation. When in use, the head assembly 320 is screwed off from the locking cover, and the elastic member 340 and the piston column assembly 330 can be repeatedly pressed and multiple liquid discharges can be achieved. The elastic member 340 can be a spring, and the piston column assembly 330 comprises a main column, a secondary column, a piston, and a glass ball arranged in sequence.

[0054] In some embodiments, the automatic pump component 200 or the manual pump component 300 is detachably connected to the pump sleeve 400 or the bottle mouth 110 by the same detachable connection mode. When the pump sleeve 400 is used, the pump sleeve 400 is also detachably connected to the bottle mouth 110. The detachable connection mode includes, but is not limited to, a threaded connection or a buckle connection, and the like. The connection between adjacent components needs to be sealed and air return channels are provided to ensure smooth flow of liquid.

[0055] In some embodiments of the present application, the automatic pump component 200 comprises a second mounting portion 210, a machine body 220, and an electric component 230. The machine body 220 comprises a first mounting cavity 221, and the machine body 220 is arranged on the second mounting portion 210 and is used to be embedded in the bottle body 100. At least part of the electric component 230 is arranged in the first mounting cavity 221. When the second mounting portion 210 is mounted on the bottle mouth 110 of the bottle body 100, at least part of the electric component 230 is located in the bottle body 100. It can be understood that the embedded automatic dispensing device can solve / improve the problems of excessive height, excessive volume, and large occupation of the exposed dispensing device. By designing a machine body 220 that can be embedded in the container and integrating the electric component 230, at least part of the electric component 230 can be accommodated in the first mounting cavity 221. When the second mounting portion 210 is mounted on the container mouth, at least part of the electric component 230 can be embedded in the container, thereby reducing the exposed height and volume, compacting the structure arrangement, and reducing the product cost to a certain extent.

[0056] In some embodiments, the second mounting portion 210 comprises a mounting end for mounting, the body 220 is arranged on the second mounting portion 210 and is configured to be embedded in a container, and the body 220 comprises a first mounting cavity 221 formed in a direction away from the mounting end. It can be understood that the embedded design of the components of the automatic dispensing device can solve / improve the problems of excessive height, excessive volume, large footprint, etc. of the exposed automatic dispensing device. By embedding the components in the packaging bottle, the volume of the automatic dispensing device exposed outside the bottle is smaller, and the height of the automatic dispensing device is also reduced. The embedded design can be that all components are embedded in the packaging bottle, such as the automatic pump component 200, except for the liquid outlet, and other components such as the battery and the pump are embedded in the packaging bottle. Alternatively, part of the components can be embedded in the packaging bottle, such as the automatic pump component 200, except for the liquid outlet, and other components are not embedded in the packaging bottle.

It can be understood that by arranging the first mounting cavity 221 and the second mounting cavity 211 adjacent to and in communication with each other, the distance between the components is designed more compactly, and the components and their functions are more integrated, which makes the product more compact and lightweight, and the appearance is also more simple and beneficial to improve the molding quality, the reduction of the amount of material used and the proportion of unqualified products also means the reduction of cost.

[0058] In some embodiments, when the electric components 230 are arranged in the second mounting cavity 211, the distance between the components can be designed to be more compact, and the components and their functions can be more integrated, so as to achieve the effect of making the product smaller and lighter. At this time, the second mounting part 210 can be arranged with other corresponding components, or the first mounting cavity 221 of the second mounting part 210 can be cancelled, so as to meet different use requirements. It can be understood that through the embedded design, the automatic liquid dispensing device is reduced in size, and the automatic pump component 200 can be more space-saving. By compressing the component size as much as possible, the automatic pump component 200 is embedded in the space inside the packaging bottle as much as possible, so as to control the volume of the part of the automatic pump component 200 exposed outside the bottle. The volume of the automatic liquid dispensing device is further reduced by visually reducing the volume of the automatic liquid dispensing device. Through the integrated design, the distance between the components can be designed to be more compact, and the components and their functions can be more integrated, so as to make the product smaller and lighter, and the appearance is more simple and beneficial to improve the molding quality. The reduction of the amount of material and the proportion of unqualified products means the reduction of cost.

[0060] In some embodiments, the order of the control assembly 231, the driving assembly 232 and the battery assembly 233 arranged along the axis can be adjusted adaptively, so as to meet different requirements and scenes.

[0069] In some embodiments, when the automatic liquid outlet device + packaging bottle (without pump sleeve 400 structure), the pumping of the liquid of the automatic liquid outlet device is mainly that the liquid in the bottle passes through the suction pipe at the bottom of the automatic liquid outlet device, then passes through the check valve at the bottom of the automatic liquid outlet device, then enters the liquid inlet seat, then enters the pump machine through the liquid pipe, then comes out through the liquid pipe, and finally is pumped out through the liquid outlet head and the liquid outlet one-way valve. The backflow of the gas in the bottle is mainly that the external air enters through the position matched by threads between the automatic liquid outlet device and the packaging bottle, then enters the bottle through the step at the position matched by the automatic liquid outlet device and the top surface of the bottle mouth 110 (the one-way pump sleeve 400 and the top surface of the bottle mouth 110 are designed to have a circumferential small rib, which is mainly to ensure that an air passage is formed between the pump body and the pump sleeve 400), to supplement the gas in the bottle, so as to realize the pumping of the liquid.

[0070] In some embodiments, when the manual liquid outlet device + packaging bottle (without pump sleeve 400 structure), the pumping of the liquid of the manual liquid outlet device is mainly that the liquid in the bottle passes through the suction pipe and the one-way valve, then enters the liquid storage cavity at the bottom of the body of the manual liquid outlet device, then is pressed to pass through the liquid hole of the auxiliary column into the auxiliary column, then passes through the main column, and finally is pumped out through the liquid outlet channel of the pressing head. The backflow of the gas in the bottle is mainly that the external air enters the body through the gap between the main column of the manual liquid outlet device and the locking cap component, then enters the inside of the one-way pump sleeve 400 through the backflow hole on the circumferential inner side of the body, then backflows to the bottle through the backflow hole on the side of the inside of the one-way pump sleeve 400 to supplement the gas in the bottle, so as to realize the pumping of the liquid.

[0071] In some embodiments of the present application, the automatic pump component 200 comprises a liquid inlet seat assembly 240, the second mounting cavity 221 comprises an outwardly extending liquid outlet arm 212, the liquid outlet arm 212 is provided with an output nozzle 250, the electric component 230 can drive the output nozzle 250 to output, the liquid inlet seat assembly 240 is arranged in the first mounting cavity 221 and is used for bearing the battery assembly 233, and the liquid inlet seat assembly 240 can communicate the inside of the bottle body 100, the driving assembly 232 and the output nozzle 250 through the liquid pipe. It can be understood that the battery assembly 233 is reliably supported through the liquid inlet seat assembly 240, at the same time, the installation position of the liquid pipe is limited, and the overall layout inside the machine body 220 is reasonable.

[0072] In some embodiments, the first liquid pipe and the second liquid pipe are included, the liquid inlet 440 is arranged on the body 220, one end of the first liquid pipe is in communication with the output nozzle 250, one end of the second liquid pipe is in communication with the liquid inlet 440, and the other end of the second liquid pipe and the other end of the first liquid pipe are respectively connected to the driving assembly 232. It can be understood that the liquid can be delivered to the output nozzle 250 by the driving assembly 2320 through the first liquid pipe and the second liquid pipe, and the first liquid pipe is arranged between the cavity inside the liquid outlet arm 212 and the second mounting cavity 211, and the first liquid pipe is arranged in the first mounting cavity 221, so that the effect of further integrated arrangement is achieved. The liquid inlet end is connected to the liquid inlet 440, the liquid outlet end is connected to the first liquid pipe, and the liquid inlet end and the liquid outlet end are in communication and arranged on one side of the mounting position.

[0073] In some embodiments of the present application, the automatic pump component 200 includes an induction assembly 260 arranged on the liquid outlet arm 212 and relatively close to the output nozzle 250, and the induction assembly 260 is electrically connected to the control assembly 231. After the automatic pump component 200 is installed to the bottle mouth 110 of the bottle body 100, it can be adjusted to rotate around the circumference of the bottle body 100, so that the circumferential position of the output nozzle 250 can be adjusted. It can be understood that the automatic pump component 200 can be adjusted to rotate around the circumference of the bottle body 100 after being installed to the bottle mouth 110 of the bottle body 100, which can be used to solve the problem of easy mis-induction of the automatic liquid outlet device and improve the user experience.

[0074] It can be understood that the root cause of the mis-induction of the automatic liquid outlet device is not only the possible damage of the device, but also the fact that the liquid taking window is generally stretched forward, because it needs to provide enough liquid taking range for the hand. Since the liquid taking induction itself has a certain distance, when the liquid taking window is stretched too far forward, it is more likely to cause the user to move closer to the liquid taking window range in the case of washing / rinsing tableware, washing hands, etc., thereby more easily causing mis-induction of liquid. In addition, the larger the induction range of the liquid taking window is designed, the greater the probability of mis-induction is. However, since the liquid taking window range of the automatic liquid outlet device is mainly designed to better meet the hand-machine size of the user for the convenience of liquid taking, if we simply want to shorten the stretching range of the liquid taking window, it will be a contradictory point. Therefore, the present scheme makes the liquid outlet device have multiple operable liquid taking directions after being matched in place with the pump cover 400, instead of a single forward direction. When mis-induction frequently occurs or is not involved in frequent liquid taking, the liquid taking window can also be turned to the left and right sides, which can well avoid the problem of mis-induction.

[0075] In some embodiments, the automatic pump component 200 and the pump cover 400 are designed through four-head positioning threads, so that the liquid outlet device has four operable liquid taking directions after being matched in place with the pump cover 400, instead of a single forward direction, thereby well avoiding the problem of mis-induction.

[0076] In some embodiments, when the overall appearance of the product is oblong, such as a liquid output device with only a single forward mating direction, the placement of the product on an offline sales shelf can affect the display of the appearance. The liquid output device with left and right direction mating and the oblong bottle can better resonate and be more beneficial to display the appearance effect.

[0077] In some embodiments, the second mounting portion 210 includes an outwardly extending liquid output arm 212, and an output nozzle 250 is arranged on the liquid output arm 212. The electric component 230 can enable the output nozzle 250 to output. The liquid output arm 212 is used to keep the output nozzle 250 at a certain distance from the bottle body to facilitate use. The output nozzle 250 is arranged at a suitable position of the liquid output arm 212, and the output is realized by the control of the electric component 230, or the automatic output is realized by the cooperation of the electric component 230 and the sensing assembly 260, so as to further achieve the effect of facilitating use. When the sensing assembly 260 senses that a preset detection object exists in the position near the output nozzle 250, it sends a signal to the control assembly 231. The control assembly 231 triggers the driving assembly 232 to actuate the output nozzle 250 to output.

[0078] In some embodiments, the liquid output arm 212 has a cavity inside, which is in communication with the second mounting cavity 211. The cavity is used to arrange a liquid pipe to enable the output nozzle 250 to normally output, and is also used to reserve space for electrical connection, so that the electric component 230 is arranged in at least one of the first mounting cavity 221 or the second mounting cavity 211, so that the overall layout is reasonable.

[0079] In some embodiments of the present application, the output nozzle 250 is provided with a one-way cut-off valve 270 along the output direction. It can be understood that the cut-off valve 270 is used to solve the problem of liquid hanging and weathering and dryness of the output nozzle of the automatic liquid output device. In some embodiments, the cut-off valve 270 is a one-way silica gel cut-off valve 270. In other embodiments, other structural forms of cut-off valve 270 can be used to meet different use requirements.

[0080] It can be understood that the conventional automatic liquid outlet device will have some liquid remaining in the mouth of the automatic liquid outlet device after taking the liquid, which is what we call the liquid hanging on the liquid outlet nozzle. And these liquid residues are not limited to the following cases, including: ① The cutting force of the liquid outlet nozzle to the content liquid is not good, and the liquid cannot be quickly cut off, resulting in the liquid hanging on the liquid outlet nozzle; ② The viscosity of the content liquid is too high and not easy to cut off; ③ After the liquid is pumped out, a small amount of liquid will remain in the liquid outlet nozzle channel. When the pump stops working, the liquid in the channel will flow down under the influence of gravity. The liquid outlet nozzle is usually designed vertically downward or downward curved, which causes the content liquid remaining in the liquid outlet nozzle channel to flow to the liquid outlet nozzle, forming a hanging liquid condition. When the liquid remaining and hanging on the automatic liquid outlet device is not removed or processed, and in the case of long-term accumulation or infrequent use, the content liquid in the liquid outlet nozzle will dry and form a dry knot and a block. Not only is there a hygiene problem, but the coagulated content liquid may also block the automatic liquid outlet device, causing the liquid to be unable to be pumped out for use or the automatic liquid outlet device to be damaged.

[0081] Therefore, in order to solve the problem of liquid hanging on the mouth of the automatic liquid outlet device after taking the liquid, a one-way silicone cutting valve 270 is added to the liquid outlet nozzle. When the automatic liquid outlet device is subjected to hand induction for liquid outlet, the one-way silicone cutting valve 270 will open due to the extrusion pressure of the liquid. After the liquid is taken, the one-way silicone valve will automatically close the opening due to its structure and material properties, quickly cutting off the liquid, thereby avoiding the liquid hanging on the liquid outlet nozzle of the liquid outlet device. In addition, the closing of the opening of the one-way silicone cutting valve 270 can also better protect the liquid inside the liquid outlet nozzle and the liquid inside the liquid outlet channel from being air dried, solving the problem of liquid weathering, dry knot and block in the liquid outlet nozzle, which also avoids bringing bad user experience at the source.

[0082] In some embodiments of the present application, the control component 231 is configured to control the driving component 232 to deliver different amounts of liquid to the output nozzle 250 for output according to the different sensing distance information detected by the sensing component 260 between the approaching object and the output nozzle 250. It can be understood that, in order to meet the usage needs of users in different scenarios, the automatic liquid output device in this embodiment does not have a completely predetermined pump-out amount for liquid taking, but has two or more different gradient pump-out amount options. Among them, the automatic liquid taking principle of the conventional automatic liquid output device mainly relies on sensing technology and intelligent control. The automatic liquid output device is usually composed of a body 220, a sensing module, a control module, a driving module, a power module, and a packaging bottle. When the user's hand approaches the sensing module, the sensing module detects the approach of the hand through infrared sensing technology and immediately sends a signal. After receiving the signal, the control module drives the motor to work, extracts the contents of the packaging bottle, and then pumps out through the liquid outlet nozzle. However, the conventional automatic liquid output device is limited by the predetermined pump-out amount, making it difficult to meet the usage needs of users in different groups and different scenarios.

[0083] To this end, the present application controls the liquid output amount by sensing the distance. When the user performs liquid taking operation of different gradient pump-out amount liquid according to his / her actual usage scenario needs, he / she only needs to sense the liquid taking according to the distance between the hand and the liquid taking window, so as to realize pumping out of different usage amounts of liquid. Thus, the cleaning scenario needs of different groups such as single person, multiple person family, etc. are met. The automatic liquid output device is more humanized, and liquid waste is avoided. This design is not only convenient to use and high in hygiene, but also accurately positions the actual liquid taking amount needs of the user, effectively reduces hand pollution, improves cleaning efficiency, avoids liquid waste, and meets the sustainable requirements of the current environment.

[0084] Referring to Figures 1 to 9 The use method of the liquid output device of the second aspect embodiment of the present application can be the use method of the liquid output device of the first aspect embodiment of the present application. The use method of the liquid output device includes the following steps:

[0086] When the automatic pump component 200 needs to be removed, the replacement pump component is installed on the bottle body 100 for use;

[0087] 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.

[0088] It can be understood that if the automatic liquid outlet device assembly needs to be charged or is damaged during use, it can be turned off, removed and replaced with a press liquid outlet device assembly for temporary use. When the charging or repair is completed, the press liquid outlet device assembly can be replaced with the automatic liquid outlet device assembly for use. In summary, the manual liquid outlet device and the automatic liquid outlet device can be used interchangeably.

[0089] In some embodiments, when using a replacement package, the following replacement operation steps are added:

[0090] Step 1: Rotate and open the refill bottle cap 120;

[0091] Step 2: Put in the automatic liquid outlet device or the manual liquid outlet device and tighten it in place;

[0092] Step 3: Use normally.

[0093] Here it is assumed that the first use is a manual liquid outlet device. If the first use is an automatic liquid outlet device, the same applies. The manual liquid outlet device and the automatic liquid outlet device can be interchanged.

[0094] In some embodiments, the bottle cap 120 sealing ring of the replacement package tightly seals the gas return hole on the one-way pump sleeve 400 to ensure that the liquid enters the inside of the pump sleeve 400.

[0095] In some embodiments, whether there is a pump sleeve 400 in the bottle body 100, the manual pump component 300 and the automatic pump component 200 of the two schemes can be used interchangeably.

[0096] The technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.
