Description

Technical Field

[0001] This disclosure relates to the field of skincare technology, specifically to a lotion bottle and a dispensing device. Background Technology

[0002] As people's living standards improve, consumers are placing higher demands on the quality and efficacy of skincare products. Skincare products such as lotions, creams, and serums generally require measured application to avoid waste from excessive dispensing or insufficient dispensing affecting the user's experience. Currently, most lotion bottles on the market use pump heads or droppers to dispense lotion. These traditional structures do not provide accurate quantitative measurement during dispensing; and the amount of pressure applied and the duration of each pump makes it difficult to precisely control the amount dispensed, resulting in significant errors and failing to meet user needs. Utility Model Content

[0003] To overcome the problems existing in the related technology, an exemplary embodiment of this disclosure provides an emulsion bottle, comprising: a bottle body with an internal space for containing emulsion, a liquid outlet formed at the bottom of the bottle body; a bottle cap disposed on the lower part of the bottle body, the outer periphery of the bottle cap extending upward to form a first cavity for containing at least a portion of the bottle body, the outer periphery of the bottle cap extending downward to form a second cavity, the first cavity and the second cavity communicating with each other; a conduit disposed in the second cavity and communicating with the liquid outlet; a liquid outlet pipe installed on the side wall of the second cavity and communicating with the conduit; a pump body disposed in the second cavity; and a plurality of movable rotors installed in the pump body, the conduit surrounding the outside of the plurality of movable rotors, the movable rotors being used to rotate and squeeze the conduit under the drive of a motor.

[0004] In some embodiments, when the lotion bottle is in storage, the movable rotor does not compress the conduit; when the lotion bottle is in use, the movable rotor compresses the conduit.

[0005] In some embodiments, the pump body includes: a top frame extending outward to form a crossbeam that abuts against the inner wall of the second cavity, and the top frame extending upward to form a column that abuts against the top wall of the second cavity; a bottom frame, the upper top surface of which is connected to the top frame, and the lower part extending downward to form a cavity for accommodating the movable rotor, and the conduit surrounding the bottom frame and located on the outer periphery of the movable rotor.

[0006] In some embodiments, the lower part of the base frame is recessed to form a first mounting groove, located below the movable rotor, and the lower end of the movable rotor is slidably mounted in the first mounting groove; the upper part of the base frame is recessed to form a second mounting groove, located above the movable rotor, and the upper end of the movable rotor is slidably mounted in the second mounting groove; wherein, the second mounting groove and the upper end of the movable rotor are detachably connected; when the emulsion bottle is in storage state, the upper end of the movable rotor is located outside the second mounting groove; when the emulsion bottle is in use state, the upper end of the movable rotor is located inside the second mounting groove.

[0007] In some embodiments, the top frame protrudes downward to form a limiting post. When the emulsion bottle is in storage, the movable rotor is tilted inward and abuts against the periphery of the limiting post, without squeezing the conduit. When the emulsion bottle is in use, the movable rotor is pushed into the second mounting groove, so that the rotor is vertically positioned and squeezes the conduit.

[0008] In some embodiments, a vacuum valve that moves up and down along the inner wall of the bottle is provided inside the bottle body, and the bottle body has a vent hole. When the emulsion is discharged from the bottle body, external gas enters the gap between the vacuum valve and the bottle body through the vent hole, causing the vacuum valve to move downward.

[0009] In some embodiments, a tail cap is provided at the top of the bottle body, and the tail cap is fixedly connected to the side wall of the bottle body. The air guide hole is opened at the top of the tail cap. The vacuum valve is slidably installed on the inner wall of the bottle body and spaced apart from the tail cap, so that the tail cap and the upper part of the vacuum valve form a gap in the bottle body to accommodate gas. The emulsion contained in the bottle body is isolated from the outside world through the vacuum valve.

[0010] In some embodiments, the bottom surface of the dispensing portion is covered with a sealing film, and the emulsion bottle further includes: a needle, installed in the middle of the bottle cap, communicating with the first cavity and the second cavity, the needle extending toward the bottle body, at least a portion of the needle being located in the first cavity, the needle being spaced apart from the sealing film when the emulsion bottle is in storage state, and the needle being used to pass through the sealing film to deliver the emulsion when the emulsion bottle is in use state.

[0011] In some embodiments, the tip extension length of the needle is less than or equal to the height of the liquid outlet.

[0012] In some embodiments, there are four movable rotors, and the gap between any two adjacent movable rotors is equal.

[0013] Secondly, this disclosure also provides a liquid dispensing device, comprising: an emulsion bottle as described in the first aspect; and a motor disposed at the lower part of the emulsion bottle for insertion between a plurality of movable rotors to drive the movable rotors to rotate and squeeze the conduit.

[0014] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0015] The emulsion bottle provided in this disclosure enables a motor to drive a movable rotor installed in the pump body. The movable rotor can squeeze and rotate the conduit, allowing the conduit to form closed and equally spaced delivery chambers between adjacent movable rotors. This achieves precise control of the emulsion output, effectively avoiding waste due to excessive output or poor user experience due to insufficient output. The emulsion bottle provided in this disclosure ensures that the emulsion output is consistent each time and has high output stability. Attached Figure Description

[0022] To overcome the above-mentioned technical problems, such as Figure 1 , Figure 3 As shown, an exemplary embodiment of this disclosure provides an emulsion bottle, which may include: a bottle body 110, a bottle cap 120, a conduit 130, a liquid outlet pipe 140, a pump body 150, and a plurality of movable rotors 160.

[0023] The bottle body 110 has an internal space for containing emulsion, and a dispensing section 111 is formed at the bottom of the bottle body 110. The bottle body 110 may be cylindrical and hollow, and the internal space for containing emulsion may be formed. The dispensing section 111 is formed at the bottom of the bottle body 110, and a dispensing port is formed at the bottom end of the dispensing section 111, through which the emulsion in the bottle can flow outward.

[0024] A bottle cap 120 is disposed on the lower part of the bottle body 110. The outer periphery of the bottle cap 120 extends upward to form a first cavity 121 for accommodating at least a portion of the bottle body 110, and the outer periphery of the bottle cap 120 extends downward to form a second cavity 122. The first cavity 121 and the second cavity 122 are interconnected. The bottle cap 120 can be disposed on the lower part of the bottle body 110 so that the liquid outlet is oriented towards the bottle cap 120, thereby achieving a seal on the bottle body 110. The outer periphery of the bottle cap 120 can extend downward to form the second cavity 122. The second cavity 122 can be a cylindrical space, and the second cavity 122 can be used to install the conduit 130, the pump body 150, and the movable rotor 160. The first cavity 121 at the top of the bottle cap 120 can also be a cylindrical space, allowing the inner wall of the first cavity 121 to fit with the bottle body 110, so that at least the lower part of the bottle body 110 is installed in the first cavity 121. The bottle cap 120 may have through holes or other conductive structures, allowing the first cavity 121 and the second cavity 122 of the bottle cap 120 to communicate with each other. The through holes or conductive structures on the bottle cap 120 can be used to install the conduit 130, allowing the conduit 130 to communicate with the liquid outlet 111. The emulsion in the bottle body 110 can flow out from the liquid outlet, pass through the through holes or conductive structures of the bottle cap 120, and enter the conduit 130 in the second cavity 122.

[0025] A conduit 130 is disposed within the second cavity 122 and communicates with the liquid outlet 111. The conduit 130 can be a flexible tube, disposed within the second cavity 122 such that one end of the conduit 130 communicates with the liquid outlet 111, allowing the emulsion in the bottle 110 to enter the conduit 130 through the liquid outlet 111. The bottle cap 120 may have a through hole or other conductive structure to connect the first cavity 121 and the second cavity 122, thereby further enabling communication between the conduit 130 within the second cavity 122 and the liquid outlet 111 of the bottle 110 installed in the first cavity 121. The emulsion can flow outward along the outlet of the liquid outlet 111, pass through the through hole or conductive structure of the bottle cap 120, and enter the conduit 130 in the second cavity 122.

[0026] A discharge pipe 140 is installed on the side wall of the second cavity 122 and communicates with the conduit 130. The discharge pipe 140 can be a conduit 130 fixedly installed on the side wall of the second cavity 122. The discharge pipe 140 can be L-shaped, with one end of its outer wall fixedly installed on the side wall of the second cavity 122, thus communicating with the interior of the second cavity 122. The discharge pipe 140 communicates with the conduit 130 inside the second cavity 122, allowing the emulsion within the conduit 130 to flow to the discharge pipe 140 and be discharged outwards. The other end of the discharge pipe 140 extends vertically downwards, forming an outlet at its lower end for the emulsion to flow out. The emulsion can flow along the extension direction of the discharge pipe 140 and ultimately flow out through the outlet to the outside of the preservation emulsion bottle, supplying it to the user. The tight connection between the outlet pipe 140 and the conduit 130 ensures good sealing of the emulsion as it flows from the conduit 130 to the outlet pipe 140, preventing it from coming into contact with the outside environment.

[0027] A pump body 150 is disposed within a second cavity 122. The pump body 150 may have an annular groove for mounting a movable rotor 160. This allows the rotor shaft of the movable rotor 160 to be mounted in the groove within the pump body 150 and to slide along the groove. The pump body 150 may be a peristaltic pump, enabling the movable rotor 160 to rotate under the drive of a motor and slide within the groove of the pump body 150.

[0028] Multiple movable rotors 160 are installed within a pump body 150, and a conduit 130 surrounds the outside of the movable rotors 160. The movable rotors 160 are used to rotate and compress the conduit 130 under the drive of a motor. The movable rotors 160 can be installed inside the pump body 150, while the conduit 130 can surround the outside of the multiple movable rotors 160, allowing the movable rotors 160 to compress the conduit 130. When the emulsion bottle is in use, the movable rotors 160 can rotate within the pump body 150 under the drive of the motor, compressing the conduit 130. This compression creates independent, sealed small spaces between adjacent movable rotors 160, the volume of which can be determined based on the distance between the movable rotors 160. By rotating the movable rotor 160 in the pump body 150 driven by a motor, the positions of these independent, enclosed small spaces change with the rotation of the movable rotor 160, gradually moving them closer to the outlet pipe 140. This allows the emulsion in the conduit 130 to be pushed out of the conduit 130 and into the outlet pipe 140 under the rotation of the movable rotor 160, and then supplied to the user via the outlet pipe 140. Since the volume of the enclosed small spaces in the conduit 130 is a fixed value, which can be determined according to the spacing of the movable rotor 160, the amount of emulsion supplied to the user each time can be constant, thus achieving continuous and precise emulsion supply.

[0029] According to the emulsion bottle provided in this embodiment, by setting a conduit 130, a pump body 150, and multiple movable rotors 160 in the second cavity 122 of the bottle cap 120, and with the conduit 130 surrounding the outside of the movable rotors 160, the emulsion bottle provided in this embodiment can achieve a precise and controllable quantitative dispensing function. Multiple movable rotors 160 rotate along the annular groove in the pump body 150 under the drive of a motor, and continuously squeeze the conduit 130 during rotation, causing the conduit 130 to form multiple small, sealed spaces of constant volume between the rotors. The emulsion can then be pushed into the dispensing pipe 140 in units of these sealed spaces, and finally flow out of the bottle body 110 for user use. The emulsion bottle provided in this embodiment provides high repeatability and precise control of each dispensing, effectively solving the problem of unstable dispensing volume caused by human squeezing force, the remaining liquid level in the bottle body 110, or changes in emulsion viscosity in traditional emulsion bottles. Furthermore, since the conduit 130 remains sealed and its internal pressure is actively controlled by the rotor, air backflow or liquid reflux is avoided, further ensuring the accuracy of the dispensing volume. In summary, this lotion bottle not only achieves high-precision, quantitative, and controllable lotion dispensing but also improves ease of use and lotion utilization. It is suitable for skincare product scenarios with high dosage control requirements, such as functional serums and repair lotions, effectively enhancing the user experience.

[0030] In some embodiments, when the lotion bottle is in a storage state, such as Figure 1 As shown, the movable rotor 160 does not compress the conduit 130; as Figure 3 As shown, when the lotion bottle is in use, the movable rotor 160 compresses the conduit 130. The storage state is the same as the lotion bottle's factory condition. In this state, the movable rotor 160 is positioned to avoid compressing the conduit 130. The lotion bottle cannot directly pump lotion to the user; the conduit 130 remains open and uncompressed, extending its lifespan and preventing damage from prolonged compression. During storage, even if the lotion bottle experiences collisions or shaking during transportation, the lotion will not leak from the conduit 130, effectively ensuring the bottle's airtightness during storage. When a user needs to pump out lotion through a lotion bottle, the lotion bottle can be adjusted to the use state. In the use state, the movable rotor 160 can squeeze the conduit 130 surrounding it, so that the conduit 130 forms multiple small sealed spaces with constant volume between the rotors. The lotion can then be pushed into the dispensing tube 140 in units of these small sealed spaces, and finally flow out of the bottle for the user to use.

[0031] According to the emulsion bottle provided in this embodiment, the movable rotor 160 is positioned in a non-contact position during factory storage or transportation, avoiding contact with the conduit 130. This prevents continuous pressure on the conduit 130, effectively extending its service life and preventing deformation, aging, and cracking due to long-term compression. Simultaneously, it effectively prevents accidental leakage of the emulsion due to external forces such as collisions and shaking, significantly improving the sealing and safety of the emulsion bottle during storage and transportation. When the user needs to use the emulsion bottle, it can be switched to the usage state. The movable rotor 160 can automatically or manually return to the working position, contacting the conduit 130 and applying pressure. At this time, the conduit 130 forms multiple small, independent, and constant-volume sealed spaces between adjacent movable rotors 160. As the motor drives the movable rotor 160 to rotate, the emulsion is pushed into the outlet pipe by unit volume, precisely controlling the output volume and ensuring consistent and quantitative emulsion output each time it is used. The emulsion bottle provided in this embodiment can ensure high-precision quantitative dispensing performance while providing higher safety. It also effectively avoids aging and permanent deformation of the conduit 130, extends the service life of the conduit 130, and improves the overall safety and structural stability of the emulsion bottle.

[0032] In some embodiments, such as Figure 2 , Figure 3 As shown, the pump body 150 may include a top frame 151 and a bottom frame 152. The top frame 151 and the bottom frame 152 of the pump body 150 may be integrally formed, or the top frame 151 and the bottom frame 152 may be fixedly connected by welding or other methods.

[0033] The top frame 151 extends outward to form a crossbeam 1511 that abuts against the inner wall of the second cavity 122, and extends upward to form a column 1512 that abuts against the top wall of the second cavity 122. The crossbeam 151 extends outward to form the top frame 1511, the end of which abuts against the inner wall of the second cavity 122, thus ensuring the stability of the pump body 150 installed in the second cavity 122 and preventing the pump body 150 from slipping and falling. The second cavity 122 can be a columnar space; therefore, the pump body 150 can be columnar as a whole for easy installation within the second cavity 122. Multiple crossbeams 1511 can be provided, and these multiple crossbeams 1511 can extend radially outward along the top frame 151. The top frame 151 can also extend upward to form a column 1512, which abuts against the top wall of the second cavity 122. Since the first cavity 121 and the second cavity 122 can be connected through a through hole or conductive structure in the middle of the bottle cap 120, and the conduit 130 needs to be connected to the liquid outlet 111 through this through hole or conductive structure, multiple pillars 1512 can be provided, arranged around the through hole in the middle of the bottle cap 120. The conduit 130 can be partially disposed in the space between the multiple pillars 1512 to facilitate communication between the conduit 130 and the liquid outlet 111. In addition, the space formed between the outer side of the pillar 1512 and the side wall of the second cavity 122 can also be used to accommodate the conduit 130, so that the conduit 130 can extend downward and be mounted around the rotor of the base frame 152.

[0034] The base frame 152 has an upper top surface connected to the top frame 151, and a lower part extending downward to form a cavity for accommodating the movable rotor 160. A conduit 130 surrounds the base frame 152 and is located on the outer periphery of the movable rotor 160. The base frame 152 can be used to mount the movable rotor 160. The upper top surface of the base frame 152 can be connected to the top frame 151, or the top frame 151 and base frame 152 can be integrally formed. The lower part of the base frame 152 forms a cavity for accommodating the movable rotor 160, and the lower top surface of the base frame 152 can support the movable rotor 160, forming a groove or track for mounting the movable rotor 160. The conduit 130 can surround the periphery of the base frame 152, so that the conduit 130 can surround the outer periphery of the movable rotor 160 installed in the base frame 152. When the user uses the lotion bottle, the movable rotor 160 can squeeze the conduit 130, so that the conduit 130 is squeezed and forms an independent sealed small space between two adjacent movable rotors 160. The lotion in the conduit 130 can be pushed out of the conduit 130 by the rotation of the movable rotor 160, enter the outlet pipe 140, and be supplied to the user through the outlet pipe 140.

[0035] According to the emulsion bottle provided in this embodiment, the coordinated support of the top frame 151 and the bottom frame 152 of the pump body 150 not only improves the installation stability of the pump body 150 in the second cavity 122, but also optimizes the layout and conduction path of the conduit 130, further enhancing the structural compactness and dispensing efficiency of the emulsion bottle. The top frame 151 can extend outward to form a crossbeam 1511 that abuts against the inner wall of the second cavity 122, serving as a limit and support to prevent the pump body 150 from shifting or falling off due to vibration during transportation or use. The top frame 151 can also extend upward to form a column 1512 that abuts against the top wall of the second cavity 122, thereby achieving stable vertical support for the pump body 150. Multiple uprights 1512 can be arranged around the through hole in the center of the bottle cap 120 to facilitate the wiring of the conduit 130. This allows the conduit 130 to avoid structural obstacles and maintain a stable arrangement as it extends from the liquid outlet 111 to the base frame 152, ensuring smooth flow of the conduit 130. Simultaneously, the base frame 152, as the supporting structure for the movable rotor 160, has a lower cavity that forms space for installing multiple rotors. The conduit 130 can then be precisely positioned around the outside of the rotor, ensuring that it forms a small, sealed space of constant size when compressed by the rotor. The combination of the top frame 151 and the base frame 152 allows for a rational arrangement of the conduit 130 within the pump body 150, ensuring stable installation and enabling high-precision and efficient quantitative dispensing, meeting the requirements of skincare products for dosage control and sealing.

[0036] In some embodiments, such as Figure 3As shown, the lower part of the base frame 152 is recessed to form a first mounting groove 1521, located below the movable rotor 160, and the lower end of the movable rotor 160 is slidably mounted in the first mounting groove 1521; the upper part of the base frame 152 is recessed to form a second mounting groove 1522, located above the movable rotor 160, and the upper end of the movable rotor 160 is slidably mounted in the second mounting groove 1522; wherein, the second mounting groove 1522 and the upper end of the movable rotor 160 are detachably connected. When the lotion bottle is in the storage state, the upper end of the movable rotor 160 is located outside the second mounting groove 1522; when the lotion bottle is in the use state, the upper end of the movable rotor 160 is located inside the second mounting groove 1522. The lower part of the base frame 152 can be recessed to form the first mounting groove 1521, the first mounting groove 1521 is located below the movable rotor 160, and the lower end of the rotor shaft of the movable rotor 160 can be mounted in the first mounting groove 1521. The first mounting groove 1521 can be annular, allowing the lower end of the rotor shaft of the movable rotor 160 to slide along the first mounting groove 1521, enabling the movable rotor 160 to move along the first mounting groove 1521. Through the compression of the conduit 130 by the movable rotor 160 and the movement and rotation of the movable rotor 160, the emulsion in the conduit 130 can be pushed out of the conduit 130 under the rotation of the movable rotor 160. The upper part of the base frame 152 can be recessed to form a second mounting groove 1522, which can be located above the movable rotor 160. The upper end of the rotor shaft of the movable rotor 160 can be installed in the second mounting groove 1522. The second mounting groove 1522 is detachably connected to the upper end of the movable rotor 160, allowing the upper end of the movable rotor 160 to be installed in or outside the second mounting groove 1522. The second mounting groove 1522 can be annular, allowing the upper end of the rotor shaft of the movable rotor 160 to slide along the second mounting groove 1522, enabling the movable rotor 160 to move along the second mounting groove 1522. Through the squeezing of the conduit 130 by the movable rotor 160 and the movement and rotation of the movable rotor 160, the emulsion in the conduit 130 can be pushed out of the conduit 130 under the rotation of the movable rotor 160. The width and diameter of the first mounting groove 1521 and the second mounting groove 1522 can be equal, so that when the lower end of the rotor shaft of the movable rotor 160 is installed in the first mounting groove 1521 and the upper end of the rotor shaft is installed in the second mounting groove 1522, the movable rotor 160 can be vertically arranged and squeeze the conduit 130 surrounding it. By driving the movable rotor 160 with a motor, the emulsion in the conduit 130 is pushed out of the conduit 130 under the rotation of the movable rotor 160 and supplied to the user through the outlet pipe 140.

[0037] According to the emulsion bottle provided in this embodiment, by providing a first mounting groove 1521 and a second mounting groove 1522 on the upper and lower parts of the base frame 152 respectively, the two ends of the movable rotor 160 can be stably and reliably positioned and slidably installed, thereby significantly improving the operational stability of the pump body 150 structure, achieving quantitative liquid dispensing, and the dispensing volume has high accuracy. The first mounting groove 1521 is provided on the lower part of the base frame 152 for slidingly installing the rotor shaft at the lower end of the movable rotor 160, and the second mounting groove 1522 is provided on the upper part of the base frame 152 for detachably installing the upper end of the rotor shaft. The first mounting groove 1521 and the second mounting groove 1522 can be in a ring shape, allowing the movable rotor 160 to rotate and slide smoothly along the first mounting groove 1521 and the second mounting groove 1522 under drive. This achieves uniform and continuous compression of the conduit 130 surrounding its outer periphery. Consequently, the movable rotor 160 maintains a vertical operating position, ensuring a stable and consistent force direction on the conduit 130 and preventing uneven deformation of the conduit 130 due to tilting or swaying, which would affect the dispensing accuracy. The lotion bottle provided in this embodiment effectively improves the accuracy of lotion dispensing, achieving quantitative dispensing and meeting the stringent requirements for dispensing volume control in skincare products.

[0038] In some embodiments, such as Figure 1 , Figure 2 As shown, when the emulsion bottle is in the storage state, the upper end of the movable rotor 160 is located outside the second mounting groove 1522, and the movable rotor 160 does not compress the conduit 130. Figure 3 As shown, when the emulsion bottle is in use, the upper end of the movable rotor 160 is installed in the second mounting groove 1522, causing the movable rotor 160 to compress the conduit 130. The emulsion bottle can have two different states: a storage state and a use state. The storage state is the factory-set state of the emulsion bottle. When the emulsion bottle is in the storage state, that is, the emulsion bottle has not been used, the user cannot obtain emulsion from the emulsion bottle. In the storage state, the movable rotor 160 can be tilted so that the upper end of the movable rotor 160 is outside the second mounting groove 1522, while the lower end of the movable rotor 160 is installed in the first mounting groove 1521. This allows the movable rotor 160 to be stably installed on the pump body 150 without compressing the conduit 130, thus preventing the emulsion bottle from supplying emulsion. In the use state, the emulsion bottle can supply emulsion to the user. By inserting the motor shaft into the pump body 150, the upper end of the movable rotor 160 is pushed outward by the motor shaft, thereby pushing the upper end of the movable rotor 160 into the second mounting groove 1522. The movable rotor 160 is pushed from an inclined state to a vertical state. The movable rotor 160 can squeeze the conduit 130 and rotate under the drive of the motor, so that the emulsion in the conduit 130 is pushed out of the conduit 130 under the rotation of the movable rotor 160 and supplied to the user through the outlet pipe 140.

[0039] The emulsion bottle provided in this embodiment effectively improves the accuracy of emulsion volume control and sealing performance. When the emulsion bottle is in storage, the movable rotor 160 is tilted, with only its lower end installed in the first mounting groove 1521 and its upper end outside the second mounting groove 1522, not contacting the conduit 130. This prevents the conduit 130 from being squeezed when not in use, preventing aging of the conduit 130 and improving the safety and stability of the product during manufacturing, transportation, and sales. When the emulsion bottle is in use, the user can insert the motor shaft into the pump body 150, causing the motor shaft to apply force to the upper end of the movable rotor 160, pushing it into the second mounting groove 1522. This switches the movable rotor 160 from the tilted state to a vertical state, thereby squeezing the conduit 130. When the rotor rotates under the drive of the motor, it squeezes the conduit 130 surrounding it, pushing the emulsion in the conduit 130 into the outlet pipe 140, allowing for quantitative dispensing and achieving precise control of the emulsion dispensing volume.

[0040] In some embodiments, a limiting post 1513 protrudes downward from the center of the top frame 151. When the emulsion bottle is in storage, the movable rotor 160 is tilted inward and abuts against the periphery of the limiting post 1513, without compressing the conduit 130. When the emulsion bottle is in use, the movable rotor 160 is pushed into the second mounting groove 1522, making the rotor vertical and compressing the conduit 130. The top frame 151 may extend downward to form a protruding limiting post 1513. The extension length of the limiting post 1513 is relatively small. When the emulsion bottle is in storage, the movable rotor 160 may be tilted inward, so that the upper end of the movable rotor 160 is located outside the second mounting groove 1522. The top of the movable rotor 160 may abut against the periphery of the limiting post 1513, allowing the movable rotor 160 to avoid the conduit 130, and the outer periphery of the movable rotor 160 abuts against the conduit 130 without compressing the conduit 130. In the storage state, when the lotion bottle is shaken or impacted by external forces, the movable rotor 160 can maintain its tilted position. The limiting post 1513 effectively restricts the position of the movable rotor 160 in the storage state, preventing positional deviation. Therefore, in the storage state, the limiting post 1513 ensures stable installation of the movable rotor 160, giving the lotion bottle high structural stability and safety. When the motor shaft is inserted between the movable rotors 160, the upper part of the movable rotor 160 can be pushed outward by the motor shaft, allowing the upper part of the movable rotor 160 to be installed in the second mounting groove 1522, and the lotion bottle can be in use. In the use state, the movable rotor 160 can be vertically positioned, with its upper end positioned in the second mounting groove 1522, allowing the movable rotor 160 to compress the conduit 130. Thus, the movable rotor 160 compresses the conduit 130 only in the use state. In the storage state, the conduit 130 is not squeezed by the movable rotor 160 and therefore will not deform. Only in the use state will the conduit 130 be squeezed by the movable rotor 160 and deform. This can effectively avoid the problem of inaccurate liquid output caused by aging of the conduit 130 and permanent deformation. It can make the conduit 130 have a longer service life and better reliability, thereby further ensuring the stability of the liquid output from the emulsion bottle and the accuracy of the liquid output.

[0041] According to the emulsion bottle provided in this embodiment, by providing a downwardly protruding limiting post 1513 in the middle of the top frame 151, the structural stability of the emulsion bottle in both storage and use states can be further improved. When the emulsion bottle is in storage state, the upper end of the movable rotor 160 is located outside the second mounting groove 1522, and the whole is in an inclined state, and its top abuts against the periphery of the limiting post 1513, thereby forming an effective limiting support. This allows the movable rotor 160 to be away from the conduit 130 in storage state, only lightly touching the surface of the conduit 130 with its outer periphery without generating a squeezing effect, effectively avoiding deformation and aging of the conduit 130 due to long-term pressure, and ensuring the elasticity of the conduit 130 and the accuracy of liquid dispensing. In addition, even if the emulsion bottle is shaken or impacted during storage and transportation, the limiting post 1513 can continuously support and limit the movable rotor 160, preventing its posture from shifting, further improving the structural stability and sealing safety of the emulsion bottle in storage state. When the emulsion bottle needs to be put into use, the motor shaft can be inserted into the gap of the movable rotor 160 to push the upper end of the movable rotor 160 into the second mounting groove 1522, changing it from an inclined state to a vertical state. This causes the motor to begin compressing the conduit 130 surrounding the rotor, achieving high-precision quantitative dispensing under motor drive. Thus, by setting the limiting post 1513, not only is the service life of the conduit 130 extended, but the stability and accuracy of the dispensing process are also improved, enabling the emulsion bottle to meet the requirements of preservation and sealing while possessing reliable, safe, and precise dispensing performance.

[0042] In some embodiments, such as Figure 2 , Figure 3As shown, a vacuum valve 112 is provided inside the bottle body 110, which moves up and down along the inner wall of the bottle body 110. A vent 113 is provided in the bottle body 110. When the emulsion is discharged from the bottle body 110, external gas enters the gap between the vacuum valve 112 and the bottle body 110 through the vent 113, causing the vacuum valve 112 to move downwards. A vacuum valve 112 can be provided inside the bottle body 110, and the vacuum valve 112 can move up and down along the inner wall of the bottle body 110. A vent 113 can be provided on the top wall of the bottle body 110, allowing external gas to enter the gap between the upper part of the vacuum valve 112 and the bottle body 110. When the emulsion bottle is in use, emulsion flows out from the outlet 111. The emulsion enters the conduit 130 through the outlet of the outlet 111, and is then squeezed by the movable rotor 160 installed in the pump body 150. This causes the conduit 130 to form an independent, sealed small space between two adjacent rotors, so that the same amount of air or emulsion is squeezed out with each rotation. The emulsion can then enter the outlet pipe 140 through the conduit 130 and finally flow out of the emulsion bottle for the user. When the air or emulsion in the conduit 130 is discharged, it causes a low pressure state in the conduit 130. The conduit 130 is connected to the bottle body 110, and the bottle body 110 is connected to the external air pressure through the air vent 113, creating a pressure difference inside the emulsion bottle. External gas can enter the gap between the vacuum valve 112 and the bottle body 110 through the air vent 113, and the air pressure pushes the vacuum valve 112 downward to squeeze the emulsion, thereby continuing to push the emulsion towards the conduit 130.

[0043] According to the emulsion bottle provided in this embodiment, the vacuum valve 112 can move downwards to compensate for the internal space of the bottle after the emulsion is discharged, based on the changes in air pressure inside and outside the emulsion bottle during use. This ensures that the inside of the bottle 110 is always under negative pressure, thereby continuously and smoothly pushing the emulsion from the outlet 111 into the conduit 130 and the outlet pipe 140 and out of the bottle 110. The emulsion bottle provided in this embodiment can effectively improve the convenience of using the emulsion bottle and ensure the accuracy of the dispensing volume. At the same time, since the movement of the vacuum valve 112 can accurately correspond to the volume change of each dispensing, the emulsion inside the bottle 110 is always in a pushed state, effectively avoiding problems such as emulsion residue and incomplete discharge caused by deformation of the bottle 110 or air entering, thereby further improving the accuracy and utilization rate of emulsion dispensing.

[0044] In some embodiments, such as Figure 2 , Figure 3As shown, a tail cap 115 is provided at the top of the bottle body 110, which is fixedly connected to the side wall of the bottle body 110. A vent 113 is provided at the top of the tail cap 115. A vacuum valve 112 is slidably installed on the inner wall of the bottle body 110, spaced apart from the tail cap 115, so that a gap for accommodating gas is formed in the bottle body 110 between the tail cap 115 and the upper part of the vacuum valve 112. The emulsion contained in the bottle body 110 is isolated from the outside through the vacuum valve 112. A tail cap 115 is provided at the top of the bottle body 110, covering the top of the first cavity. A vent 113 can be provided at the top of the tail cap 115. A connecting part for connecting with the side wall of the bottle body 110 can be formed downward on the periphery of the tail cap 115. The connecting part can cooperate with the top of the side wall of the bottle body 110, so that the tail cap 115 is fixedly connected to the top of the side wall of the bottle body 110. Specifically, the top of the side wall of the bottle body 110 extends upward to form an extension portion, and the outer periphery of the extension portion extends outward to form an outwardly protruding annular locking portion. The inner side of the connecting portion of the tail cap 115 forms an outwardly recessed annular groove. When the tail cap 115 is placed on top of the bottle body 110, the annular locking portion can be installed in the annular groove, thereby fixing the tail cap 115. The vacuum valve 112 can be slidably installed on the inner wall of the bottle body 110, and the vacuum valve 112 is spaced apart from the tail cap 115, so that a gap for accommodating gas is formed between the upper part of the tail cap 115 and the vacuum valve 112 in the bottle body 110. When the vacuum valve 112 is installed inside the bottle body 110, the space below the vacuum valve 112 inside the bottle body 110 is a sealed space isolated from the outside, which can be used to contain emulsion, thereby achieving the preservation of the emulsion. When the emulsion bottle is in storage mode, the movable rotor 160 avoids the conduit 130, preventing it from being compressed, thus allowing air to remain inside the conduit 130 and preserving the emulsion within the bottle body 110. When the emulsion bottle is put into use mode, the movable rotor 160 compresses the conduit 130 and rotates with the drive of the motor, expelling the air from the conduit 130 and creating a low-pressure environment within it. The conduit 130 is connected to the bottle body 110. In this situation, because the tail cap 115 has a vent 113, the bottle body 110 is connected to the external air pressure through the vent 113, resulting in a pressure difference within the emulsion bottle system. The external air pressure can push the vacuum valve 112 downwards, squeezing the emulsion towards the conduit 130 until the emulsion reaches the outlet pipe 140 and is discharged.

[0045] According to the emulsion bottle provided in this embodiment, by setting a tail cap 115 on the top of the bottle body 110 and opening a vent hole 113 on the top of the tail cap 115, and cooperating with the vacuum valve 112 structure slidably installed on the inner wall of the bottle body 110, a sealed liquid storage chamber and an isolated gas buffer chamber are formed inside the bottle body 110. This ensures that the emulsion is isolated from the outside air while possessing excellent sealing and preservation performance. The tail cap 115 is fixedly connected to the side wall of the bottle body 110 by a snap-fit ​​structure, which not only makes assembly simple and the structure sturdy, but also ensures the relative position of the vent hole 113 is stable, which is conducive to forming a stable and controllable air pressure channel. When the emulsion bottle is in storage, a gap is formed above the vacuum valve 112. Although the vent 113 is connected to the outside, the vacuum valve 112 remains in its current position because the air pressure inside and outside the emulsion bottle is the same. The emulsion is effectively sealed in the sealed cavity below the vacuum valve 112, preventing the emulsion from contacting air, extending its shelf life, and preventing liquid leakage during transportation and shaking, significantly improving the safety of product storage and transportation and the user experience. When the emulsion bottle is in use, the motor drives the movable rotor 160 to rotate and squeeze the conduit 130, creating a low-pressure area inside the conduit 130. The conduit 130 is connected to the cavity inside the bottle body 110 used to contain the emulsion. At this time, under the action of external air pressure, air enters the upper gap area of ​​the bottle body 110 through the vent 113 of the tail cap 115, pushing the vacuum valve 112 to slide downward and generating pressure on the emulsion, thereby causing the emulsion to be transported along the conduit 130 and quantitatively discharged to the outlet pipe 140, thus realizing automated pneumatic-assisted liquid supply. The emulsion bottle provided in this embodiment can achieve both sealing and preservation of the emulsion, and in use, it can achieve a stable and continuous emulsion supply through the linkage of air pressure difference and vacuum valve 112, thereby enhancing the sealing performance, reliability and functionality of the emulsion bottle.

[0046] In some embodiments, such as Figure 2 , Figure 3As shown, the bottom surface of the dispensing section 111 is covered with a sealing film 114. The emulsion bottle also includes a needle 170, installed in the middle of the bottle cap 120, connecting the first cavity 121 and the second cavity 122. The needle 170 extends towards the bottle body 110, with at least a portion of the needle 170 located within the first cavity 121. When the emulsion bottle is in storage, the needle 170 and the sealing film 114 are spaced apart. When the emulsion bottle is in use, the needle 170 is used to pass through the sealing film 114 to deliver the emulsion. The bottom of the bottle body 110 may have a dispensing section 111, with a dispensing port at the bottom end of the dispensing section 111. The emulsion in the bottle body 110 can flow outward through the dispensing section 111 and the dispensing port. The bottom surface of the dispensing section 111 may be covered with a sealing film 114, which can seal the dispensing port, thereby ensuring a high degree of airtightness of the bottle body 110 when the emulsion bottle is in storage. The emulsion in bottle 110 can avoid contact with external air, water and impurities during storage, so that the emulsion stored in bottle 110 has a good sealing effect during storage, thereby achieving the preservation of the emulsion in bottle 110.

[0047] The needle 170 can be installed in the center of the bottle cap 120, allowing the first cavity 121 and the second cavity 122 to communicate through the needle 170. The needle 170 can extend towards the bottle body 110, allowing the tip of the needle 170 to extend into the first cavity 121. When the emulsion bottle is in storage, the needle 170 and the sealing film 114 are spaced apart, keeping the bottle body 110 sealed and providing a good sealing and preservation effect. When the emulsion bottle is in use, the bottle body 110 can be pressed down, allowing the needle 170 to pass through the sealing film 114. The end of the needle 170 facing the second cavity 122 can communicate with the dispensing component, allowing the emulsion to flow from the needle 170 to the dispensing component, thus discharging the emulsion out of the emulsion bottle. When the lotion bottle is in use, the lotion inside the bottle 110 can only flow out through the needle 170. Since the cap 120 is located at the bottom of the bottle 110, it further preserves the lotion while in use, preventing it from contacting outside air and effectively blocking the entry of air and contaminants. This ensures that the lotion bottle maintains good preservation even when the user is using it. Using the lotion bottle provided by this disclosure effectively prevents the oxidation of moisture, organic matter, and active ingredients in the lotion or the growth of microorganisms. The lotion bottle provided by this disclosure offers excellent preservation, resulting in better stability of the active ingredients in the lotion, significantly extending its shelf life, reducing waste, and improving product efficiency. Furthermore, due to its superior preservation effect, the lotion bottle provided by this disclosure ensures that its texture, color, and odor remain stable during use, resulting in a better user experience.

[0048] According to the emulsion bottle provided in this embodiment, the bottom surface of the dispensing part 111 is covered with a sealing film 114, and a needle 170 that can penetrate the sealing film 114 is provided on the bottle cap 120. Figure 2 As shown, when the emulsion bottle is in storage, the needle 170 remains spaced from the sealing film 114, and the emulsion is completely sealed inside the bottle body 110, effectively preventing the entry of external air, moisture, and impurities. This significantly improves the emulsion's sealing and preservation capabilities, preventing oxidation of active ingredients or microbial growth. When the emulsion bottle is in use, the user can puncture the sealing film 114 by pressing down on the bottle body 110, allowing the needle 170 to pierce the sealing film 114 and connect with the bottle body 110, enabling the emulsion to be delivered from inside the bottle body 110 through the needle 170 to the external dispensing component. The emulsion bottle provided in this embodiment not only extends the shelf life of the emulsion and maintains product efficacy and stability, but also effectively prevents leakage or contamination caused by poor sealing during storage or transportation of traditional bottled emulsions. Meanwhile, in conjunction with the bottle cap 120 sealing structure and the needle 170 penetration structure, the needle 170 can only penetrate the sealing film 114 when the user uses it for the first time, ensuring that the emulsion is always in a vacuum-sealed state from the time it leaves the factory until it is used. This achieves a higher standard of sealing and preservation performance, improving the product user experience and user satisfaction.

[0049] In some embodiments, the tip extension length of the needle 170 is less than or equal to the height of the dispensing portion 111. Since the tip of the needle 170 needs to pierce the film covering the bottom of the dispensing portion 111 during use, the emulsion in the bottle 110 can flow out along the needle 170, enter the dispensing assembly, and finally flow out to the outside. When the remaining amount of emulsion in the bottle 110 is low, and the emulsion level is lower than the height of the needle tip 170, the emulsion will accumulate in the bottle 110 and cannot be supplied to the user, resulting in waste. Therefore, the length of the needle tip extending into the bottle 110 can be less than or equal to the height of the dispensing portion 111, allowing more emulsion to pass through the needle 170 into the dispensing portion 111, reducing emulsion waste. Since the cross-sectional area of ​​the dispensing portion 111 is smaller than the cross-sectional area of ​​the upper part of the bottle 110, there is less emulsion at the dispensing portion 111, and making the tip extension length of the needle 170 less than or equal to the height of the dispensing portion 111 further reduces emulsion waste. In addition, in some embodiments, an inwardly inclined slope can be formed from the top of the liquid outlet 111, so that the emulsion can flow back into the needle 170 along the slope, making the liquid outlet smoother and avoiding waste caused by the accumulation of emulsion on the plane above the liquid outlet 111.

[0050] According to the emulsion bottle provided in this embodiment, by setting the length of the tip of the needle 170 extending towards the bottle body 110 to be less than or equal to the height of the dispensing section 111, the emulsion in the bottle body 110 can be utilized to the maximum extent, reducing emulsion residue and waste. When the emulsion gradually decreases and approaches the bottom of the bottle body 110, if the tip of the needle 170 is located at or near the bottom of the dispensing section 111, even if the emulsion level is lower than the height of other parts of the bottle body 110, the remaining emulsion can still be smoothly discharged through the needle 170, ensuring more efficient use of the emulsion, extending the usage cycle, and reducing waste. The top of the dispensing section 111 can also be provided with an inwardly inclined slope structure. This structure can effectively guide the emulsion to naturally converge along the slope to the inlet of the needle 170. Even if the emulsion adheres to the inner wall or periphery of the dispensing section 111, it can be guided back by the slope, thereby avoiding residue and waste caused by the accumulation of emulsion on a local plane.

[0051] In some embodiments, there are four movable rotors 160, with equal gaps between any two adjacent movable rotors 160. The four movable rotors 160 are evenly distributed and installed in the pump body 150. The bottom of each movable rotor 160 is installed in the first mounting groove 1521, and the distance between the bottoms of any two adjacent movable rotors 160 is equal. This ensures that, in use, the conduit 130 forms equally sized and independent sealed small spaces between adjacent movable rotors 160. As the movable rotors 160 rotate with the motor shaft, each rotation allows the emulsion or air in an independent sealed small space to be discharged outward through the outlet pipe 140. Therefore, when the motor drives the movable rotors 160 to rotate, each rotation squeezes out the same amount of air or emulsion from the conduit 130 and discharges it out of the emulsion bottle through the outlet pipe 140, thereby achieving quantitative dispensing. The accuracy of the liquid output can be determined based on the gap between every two adjacent movable rotors 160, and the accuracy of the liquid output can reach 0.1ml±0.02ml.

[0052] According to the emulsion bottle provided in this embodiment, by setting four evenly distributed movable rotors 160 in the pump body 150, with equal gaps between adjacent movable rotors 160, the conduit 130 can form a uniform, independent, sealed small space between any two movable rotors 160, thereby achieving continuous and uniform quantitative delivery during the rotation of the movable rotors 160. The emulsion bottle provided in this embodiment effectively solves the problem of liquid output fluctuation caused by uneven placement and inconsistent gaps of the movable rotors 160, effectively improving the liquid output accuracy. Furthermore, the symmetrical arrangement of the movable rotors 160 with uniform gaps also helps reduce vibration and wear during operation, improves system stability and durability, further extends product lifespan, and reduces maintenance costs.

[0053] Based on the same inventive concept, this disclosure also provides a liquid dispensing device, such as... Figure 2 , Figure 3 As shown, it may include: a lotion bottle and a motor 210 as in any of the foregoing embodiments.

[0054] The emulsion bottle has a bottle body 110 for containing emulsion. A cap 120 is placed on the bottom of the bottle body 110, so that the bottle body 110 is partially installed in a first cavity 121 formed above the cap 120. A conduit 130 can be disposed in a second cavity 122 below the emulsion bottle, with one end of the conduit 130 communicating with a liquid outlet 111 formed at the bottom of the bottle body 110, allowing the emulsion in the bottle body 110 to enter the conduit 130 through the liquid outlet 111. The other end of the conduit 130 can be communicated with a liquid outlet pipe 140, allowing the liquid to be transported from the conduit 130 to the liquid outlet pipe 140, and finally flow out and be supplied to the user. A pump body 150 can also be disposed in the second cavity 122, and a movable rotor 160 is disposed in the pump body 150, which can be arranged around the central axis of the pump body 150. The conduit 130 can surround the outer periphery of the movable rotor 160, allowing the movable rotor 160 to rotate and squeeze the conduit 130 under the drive of the motor 210. This compression creates independent, sealed small spaces between adjacent movable rotors 160. During dispensing, one of these independent sealed small spaces can be squeezed out at a time, achieving a quantitative discharge of the emulsion. The space between the multiple movable rotors 160 can be used to insert the motor shaft of the motor 210. After insertion, the motor shaft can rotate and drive the movable rotors 160 to rotate, allowing the movable rotors 160 to squeeze the conduit 130 and push the emulsion in each independent sealed small space within the conduit 130 towards the outlet pipe 140 for discharge.

[0055] A motor 210, located at the bottom of the emulsion bottle, is inserted between multiple movable rotors 160 to drive the movable rotors 160 to rotate and squeeze the conduit 130. The motor 210 can be positioned at the bottom of the emulsion bottle, mounted on the pump body 150, and its shaft can be inserted between the movable rotors 160. Rotation of the motor shaft causes the movable rotors 160 to rotate and move around the motor shaft, thereby squeezing the conduit 130 and pushing the emulsion in each individual sealed space within the conduit 130 towards the outlet pipe 140 for discharge. This enables automated emulsion discharge. The motor 210 can rotate one revolution per cycle, or the rotation angle can be determined based on the rotor arrangement. Each time the motor 210 is activated, the movable rotors 160 squeeze the conduit 130, moving the emulsion in an individual sealed space towards the outlet pipe 140 for discharge. This ensures that each time the dispensing device is activated, only a certain amount of emulsion is discharged, achieving accurate control of the emulsion discharge volume.

[0056] According to the dispensing device provided in this embodiment, by integrating the emulsion bottle, pump body 150, conduit 130, and motor 210, and using the motor 210 to drive multiple movable rotors 160 to rotate and squeeze the conduit 130, a high-precision and automated quantitative dispensing function can be achieved with a compact structure. In particular, the independent, sealed small space formed by the conduit 130 among the multiple movable rotors 160, combined with the precise drive control of the motor 210, allows a fixed volume of emulsion to be discharged with each rotation, thereby achieving consistency and predictability of the dispensing volume. The dispensing device in this embodiment not only has good quantitative control capability but also good sealing performance, which can effectively prevent emulsion leakage when not in operation. In addition, the inverted installation structure of the emulsion bottle combined with the bottom-integrated dispensing mechanism further simplifies the liquid delivery path, reduces residue and waste, and improves emulsion utilization.
