Description

[Technical Field]

[0001] The present invention belongs to the technical field of electric paste dispensing equipment, and particularly relates to a stand and an electric dispensing device. [Background technology]

[0002] People use cosmetics, skin care products, toothpaste, and other paste-type products every day to care for their bodies. For example, in oral hygiene, when brushing teeth, toothpaste is usually squeezed out manually. The manual toothpaste squeezing method is inefficient and the amount of toothpaste squeezed out is not precise, so toothpaste is easily left behind, resulting in waste.

[0003] As a result, electric toothpaste dispensers have emerged, replacing manual toothpaste squeezing. Most current electric toothpaste dispensers are connected to a toothpaste container and are typically used as disposable consumables. When a user uses toothpaste, the drive mechanism within the dispenser drives the squeezer assembly within the container to squeeze out the paste. When the drive mechanism within the dispenser and the squeezer assembly within the container are connected, there are often problems with the connection being unstable, which can easily lead to malfunctions in the electric toothpaste dispenser and reduce the efficiency of toothpaste squeezing. Furthermore, because the dispenser and the toothpaste container are connected to each other, the electric toothpaste dispenser cannot be reused after the toothpaste is used up. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0051] Terms such as "first," "second," "third," etc. are for descriptive purposes only and do not represent sequence numbers or imply or express relative importance.

[0052] Furthermore, terms such as "horizontal," "vertical," and "gravity direction" do not mean that a component is placed absolutely horizontally or vertically, but may be slightly tilted. For example, "horizontal" means that the orientation of the component is merely more horizontal than "vertical," and does not necessarily require that the component be completely horizontal, but may be slightly tilted.

[0053] In describing this invention, the directions or positional relationships expressed by terms such as "inside," "outside," "left," "right," "up," and "down" are based on the drawings or are the normal arrangement directions or positional relationships of products according to this invention, and are merely for the purpose of simply and concisely explaining this invention. The relevant devices or parts do not necessarily have a specific direction or are configured or operated in a specific direction, and therefore do not limit this invention.

[0054] In describing the present invention, unless otherwise specified, the terms "installation," "mounting," "coupling," and "connection" should be understood in a broad sense. For example, they may refer to a fixed connection, a detachable connection, or an integral connection. They may also refer to a mechanical connection or an electrical connection. They may also refer to a direct connection, an indirect connection via an intermediate, or internal communication between two elements.

[0055] The technical solution of the present invention will be described below with reference to the drawings.

[0056] As shown in Figures 1, 2, 3, 4, and 5, the present invention provides a stand 11. The stand 11 includes a stand body 100, a driving member 200, a transmission structure 300, a connecting member 400, a control unit 500, and an electrical supply unit 600. The driving member 200 is installed within the stand body 100, and the transmission structure 300 is installed within the stand body 100 and connected to the driving member 200. The transmission structure 300 is installed with a connecting member 400, which is for fixedly connecting with the transmission squeezing structure in the squeezing container when the stand 11 and the squeezing container are assembled. The driving member 200 drives the transmission structure 300, which in turn drives the transmission squeezing structure fixedly connected to the connecting member 400, thereby squeezing out the ingredients. The control unit 500 is installed within the stand body 100 and is electrically connected to the driving member 200. The power supply unit 600 is installed in the stand body 100 and is electrically connected to the control unit 500 and the driving member 200 .

[0057] In this embodiment, when the control unit 500 issues a command, it controls the operation of the driving member 200, which then drives the transmission structure 300 to transmit power, thereby achieving automatic control of the stand 11. This eliminates the need for manual operation by the user and is easy to use. The stand 11 is assembled and connected to a squeezing container to automatically control the squeezing of ingredients in the squeezing container. The connecting member 400, located within the stand 11 and installed on the transmission structure 300, is stably and effectively connected to the transmission squeezing structure in the squeezing container, thereby solving the problem of mechanical failure when the driving member 200 drives the operation of the transmission structure 300 to drive the transmission squeezing structure to squeeze ingredients, and improving the work efficiency of the stand 11 when automatically squeezing ingredients.

[0058] The dispenser can accommodate different materials for different applications, and in some embodiments, the stand 11 can be used to automatically dispense materials for oral care, beauty and personal care, medicine, industrial construction, and other applications.

[0059] For example, in an oral care application scenario, the material contained in the squeeze container may be toothpaste, toothpaste powder, oral care liquid, etc. The user simply assembles and connects the stand 11 of the present invention to the squeeze container containing the material, and then stably connects the connecting member 400 installed on the transmission structure 300 in the stand 11 to the transmission squeezing structure in the squeeze container. After the connection is complete, the user starts the stand 11, and the control unit 500 controls the driving member 200, which in turn controls the operation of the transmission structure 300 to drive the transmission squeezing structure in the squeeze container to automatically squeeze out the toothpaste, toothpaste powder, oral care liquid, etc. In this way, the user can automatically squeeze out materials such as toothpaste, toothpaste powder, oral care liquid, etc. by simply installing and operating the stand 11, eliminating the need for manual squeezing by the user, making it easier to use, more environmentally friendly, reducing waste, and improving the user experience.

[0060] For example, in beauty and personal care applications, the materials contained in the squeeze container may be lotion, essence, emulsion, face cream, cleanser, paste mask, etc. When a user installs and operates stand 11, the materials such as lotion, essence, emulsion, face cream, cleanser, paste mask, etc. can be automatically squeezed out, eliminating the need for manual squeezing by the user, making use easier, more hygienic, and improving the user experience.

[0061] For example, in a medical application scenario, the material contained in the squeeze container may be a disinfectant (e.g., alcohol, Oxyful, etc.), a liquid medicine, a paste-like medicine, a medicinal powder, etc. When a user attaches and operates stand 11, materials such as a disinfectant (e.g., alcohol, Oxyful, etc.), a liquid medicine, a paste-like medicine, or a medicinal powder can be automatically squeezed out, eliminating the need for the user to manually squeeze out the materials, making use easier, more hygienic, and improving the user experience.

[0062] For example, in industrial construction applications, because the amount of material used in industrial construction is relatively large, the squeezer can have a tank structure with a relatively large capacity, and the corresponding stand structure and volume are also relatively large. Materials stored in the squeezer include cement, lime paste, lime powder, etc. Workers use crane equipment to assemble and connect the stand and squeezer, and then operate the stand to automatically squeeze out the cement, lime paste, lime powder, etc., thereby replacing manual labor and improving work efficiency.

[0063] For convenience of explanation, the stand 11 of the present invention will be described as being applied to an oral care scene, and the stand 11 is configured to cooperate with a squeeze bottle to automatically squeeze out toothpaste paste.

[0064] The stand body 100 is a housing structure of the stand 11 and has an accommodation space in which the driving member 200, the transmission structure 300, the control unit 500, the power supply unit 600 and other electrical components are accommodated.

[0065] In some embodiments, the stand body 100 is a housing made of polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate (PETG), polylactic acid (PLA), acrylonitrile-butadiene-styrene plastic (ABS), thermoplastic polyurethane (TPU), etc. The material of the stand body 100 can be selected according to actual needs.

[0066] In some embodiments, the drive member 200 is a servo motor, a stepper motor, a brushless motor, or the like.

[0067] As shown in Figures 3, 4, 5, 6 and 7, the transmission structure 300 includes a bracket 310 and a transmission member 320, the transmission member 320 is installed on the bracket 310, the output end of the driving member 200 penetrates the bracket 310 and is connected to the transmission member 320, and the connecting member 400 is installed on an end of the transmission member 320 away from the output end of the driving member 200.

[0068] In this embodiment, the bracket 310 serves to fix the transmission member 320 and provide support to the transmission member 320. The output end of the driving member 200 passes through the bracket 310, so that the bracket 310 provides a certain amount of support to the driving member 200 and fixes the driving member 200. The output end of the driving member 200 is connected to one end of the transmission member 320, and the other end of the transmission member 320 is connected to the connecting member 400. The driving member 200 drives the transmission member 320 to transmit power to the connecting member 400.

[0069] In the first embodiment of the present invention, the transmission member 320 is a screw shaft, one end of which is connected to the output end of the driving member 200, and the other end of which is connected to the connecting member 400, which is connected to the transmission squeezing structure in the squeezing container.

[0070] For example, a drive-driven squeezing structure comprises a screw and a piston, the piston being attached to the screw, and the forward and reverse drive of the screw drives the piston to move forward or backward along the axial direction of the screw, thereby enabling the piston to automatically squeeze out the toothpaste paste in the squeezing container.

[0071] Therefore, in the first embodiment of the present invention, the transmission member 320 is configured as a screw shaft, and is connected to the screw of the transmission dispensing structure by the connecting member 400. During an operation, the control unit 500 issues a command to control the driving member 200 to operate. After the driving member 200 receives the command, it drives the transmission member 320 to rotate. The rotation of the transmission member 320 drives the screw connected by the connecting member 400 to rotate, thereby driving the piston to advance along the axial direction of the screw and automatically dispensing the toothpaste paste in the dispensing bottle. The transmission structure 300 in the first embodiment enables automatic dispensing of single-component toothpaste paste.

[0072] In a second embodiment of the present invention, the transmission member 320 includes a first transmission member 321 and a second transmission member 322. The output end of the driving member 200 is connected to the first transmission member 321, the first transmission member 321 and the second transmission member 322 are meshed with each other to transmit power, and the connecting member 400 is installed on the second transmission member 322.

[0073] In one embodiment of the second example, the first transmission member 321 is a driving gear, and the second transmission member 322 is a driven gear. The driving gear is installed at the output end of the driving member 200, and the driving gear and the driven gear mesh together to transmit power. The driving member 200 drives the driving gear to rotate, and the driving gear and the driven gear mesh together to transmit power, thereby realizing synchronous rotation of the driven gear.

[0074] The drive-driven dispensing mechanism will be described using a screw and piston as an example. The output end of the drive member 200 is connected to the first transmission member 321, and the first transmission member 321 and the second transmission member 322 mesh with each other to transmit power. The second transmission member 322 is connected to the screw of the drive-driven dispensing mechanism by the connecting member 400. During an operation, the control unit 500 issues a command to control the drive member 200 to operate. After the drive member 200 receives the command, it rotates the first transmission member 321, and the first transmission member 321 and the second transmission member 322 mesh with each other to transmit power, thereby rotating the second transmission member 322. The rotation of the second transmission member 322 rotates the screw connected by the connecting member 400, thereby driving the piston to advance along the axis of the screw, automatically squeezing out the toothpaste from the dispenser. The transmission mechanism 300 in this embodiment can also realize automatic squeezing of single-component toothpaste.

[0075] As another embodiment of the second embodiment, the transmission member 320 may be a planetary gear set.

[0076] 6 and 7, in a third embodiment of the present invention, a transmission member 320 includes a first transmission member 321, a second transmission member 322, and a third transmission member 323. The output end of the driving member 200 is connected to the first transmission member 321, the first transmission member 321 and the second transmission member 322 are meshed together to transmit power, and the second transmission member 322 and the third transmission member 323 are meshed together to transmit power, and a connecting member 400 is installed on the third transmission member 323.

[0077] In this embodiment, three transmission members 320 are installed, and the output end of the driving member 200 is connected to the first transmission member 321. The first transmission member 321 and the second transmission member 322 are meshed with each other to transmit power, and the second transmission member 322 and the third transmission member 323 are meshed with each other to transmit power. Through the meshing and transmission of each transmission member, the driving force of the driving member 200 is transmitted to the transmission squeezing structure, thereby realizing automatic squeezing of the toothpaste paste in the squeezing container.

[0078] 6 and 7, as one embodiment of the third example, the second transmission member 322 includes a rotating shaft 3221, a first sub-transmission member 3222, and a second sub-transmission member 3223. The rotating shaft 3221 is rotatably mounted on the bracket 310, the first sub-transmission member 3222 and the second sub-transmission member 3223 are mounted coaxially on the rotating shaft 3221, the first transmission member 321 and the first sub-transmission member 3222 mesh with each other to transmit power, and the second sub-transmission member 3223 and the third transmission member 323 mesh with each other to transmit power.

[0079] The rotating shaft 3221 is mounted on the bracket 310 and is rotatable on the bracket 310, and the first sub-transmission member 3222 and the second sub-transmission member 3223 are mounted coaxially on the rotating shaft 3221, i.e., the first sub-transmission member 3222 and the second sub-transmission member 3223 are rotatable synchronously. The output end of the driving member 200 is connected to the first transmission member 321, and the driving member 200 rotates the first transmission member 321. The rotation of the first transmission member 321 rotates the first sub-transmission member 3222 that is engaged with the first transmission member 321. The rotation of the first sub-transmission member 3222 rotates the second sub-transmission member 3223 that is installed coaxially with the first sub-transmission member 3222. The rotation of the second sub-transmission member 3223 rotates the third transmission member 323 that is engaged with the second sub-transmission member 3223. In this way, one driving member 200 can drive multiple transmission members to transmit driving force. This transmission structure can solve the technical problem of excessive stand volume when installing multiple driving members.

[0080] For example, the first transmission member 321 is a worm, the first sub-transmission member 3222 is a worm wheel, and the worm and worm wheel mesh together to transmit power, the second sub-transmission member 3223 is a drive gear, and the third transmission member 323 is a driven gear, and the drive gear and driven gear mesh together to transmit power. Two second sub-transmission members 3223 are provided, and the two second sub-transmission members 3223 are provided symmetrically on both sides of the first sub-transmission member 3222 and are provided coaxially with the first sub-transmission member 3222 and the rotating shaft 3221. Two third transmission members 323 are provided, and each third transmission member 323 is meshed with a second sub-transmission member 3223 in a one-to-one relationship to transmit power. The ends of each third transmission member 323 are connected to corresponding connecting members 400, and the other ends of the two connecting members 400 are connected to two screws in the squeezing container.

[0081] The worm wheel / worm has the advantages of a large reduction ratio, large transmission torque, and high transmission efficiency, etc. Therefore, in order to achieve a compact and efficient stand 11, the present invention uses a two-stage worm wheel / worm reduction transmission structure 300, which reduces the overall volume and weight of the stand 11 and makes it easy for users to hold.

[0082] During an operation, the control unit 500 issues a command to control the operation of the driving member 200. After the driving member 200 receives the command, it rotates the first transmission member 321. The rotation of the first transmission member 321 rotates the first sub-transmission member 3222 meshing with the first transmission member 321. The rotation of the first sub-transmission member 3222 rotates the two coaxial second sub-transmission members 3223. The rotation of the two second sub-transmission members 3223 rotates the two third transmission members 323 meshing with the second sub-transmission members 3223. The rotation of the two third transmission members 323 rotates the connecting members 400 connected to the two third transmission members 323, and the two connecting members 400 are further connected to the two screws in the squeeze container, respectively. The driving member 200 drives the worm to rotate, and multiple transmission members are driven by one driving member through the meshing of the worm wheel and the worm and the meshing transmission between gear sets. The driving force of the driving member 200 is transmitted to the connecting member 400 through the meshing transmission of the multiple transmission members, and then to the transmission squeezing structure connected to the connecting member 400, which enables the toothpaste with two different ingredients to be automatically squeezed out.

[0083] The stand 11 of this invention can automatically dispense not only toothpastes with one or two compositions, but also toothpastes with a wider variety of compositions. To accommodate the need for automatic dispensing of toothpastes with multiple different compositions, the transmission members 320 in the transmission structure 300 can be optimized, for example, by increasing the number of second sub-transmission members 3223, the number of connecting members equal to the number of second sub-transmission members 3223, and the number of screws in the transmission dispensing structure equal to the number of second sub-transmission members 3223 and located within the dispensing container. The worm-wheel-worm meshing transmission and the drive gear-driven gear meshing transmission enable one driving member to drive multiple transmission members, thereby achieving synchronous dispensing of materials with multiple compositions within the dispensing container.

[0084] 6 and 8, the connecting member 400 includes a connecting shaft 410 and an elastic member 420. The connecting shaft 410 is provided with a connecting portion 411, which is for fixed connection to a transmission component of the transmission squeeze structure. The elastic member 420 is connected to the connecting shaft 410, and the elastic member 420 is connected to the transmission structure 300.

[0085] In this embodiment, the connecting shaft 410 is provided to ensure a stable connection between the transmission member 320 and the transmission structure. The elastic member 420 is provided below the end of the connecting shaft 410 that is remote from the transmission structure. When the driving member 200 drives the transmission member 320 to rotate by a relatively small angle, the elasticity of the elastic member 420 ensures that the coupling portion 411 of the connecting shaft 410 and the transmission components of the transmission structure are securely fitted together. This prevents the transmission member 320 and the transmission components from being stably and accurately coupled together due to a mismatch between the coupling portion 411 and the transmission components. The transmission components of the transmission structure may be the screw described above.

[0086] In some embodiments, as shown in FIG. 6 , the connecting portion 411 is configured as a male connecting head or a female connecting head. As described above, the connecting portion 411 is for connecting with a screw in a power-driven squeezing structure. The end of the screw that connects with the connecting member 400 is usually configured as a male connecting head or a female connecting head, and the connecting portion 411 of the connecting member 400 can be mated with the end of the screw. That is, if the end of the screw is a male connecting head, the connecting portion 411 that connects with the male connecting head of the screw is a female connecting head. If the end of the screw is a female connecting head, the connecting portion 411 that connects with the female connecting head of the screw is a male connecting head. The mating connection between the male connecting head and the female connecting head improves the stability of the connection and prevents the screw and the connecting member 400 from coming loose when connected.

[0087] In some embodiments, the cross section of the connecting portion 411 is circular or polygonal. When the male connecting head of the screw is an outwardly protruding polygonal protrusion base, the connecting portion 411 is a sleeve-shaped female connecting head having an inwardly concave polygonal structure and a circular outer contour. When the female connecting head of the screw is a sleeve-shaped male connecting head having an inwardly concave polygonal structure and a circular outer contour, the connecting portion 411 is an outwardly protruding polygonal protrusion base. Whether it is a male connecting head or a female connecting head, the cross section of the connecting portion 411 can be circular or polygonal. Providing the cross section of the connecting portion 411 with a polygonal structure can prevent the screw from rotating uncontrollably and contribute to quick alignment and connection between the screw and the connecting member 400.

[0088] Therefore, in this invention, by installing the connecting member 400, the squeeze bottle and the stand 11 can be assembled separately, so that the user only needs to replace the used up squeeze bottle of toothpaste and the stand 11 can continue to be used. This solves the problem in the prior art automatic paste dispensers that the entire automatic paste dispenser must be replaced after the toothpaste is used up.

[0089] In some embodiments, the control unit 500 includes a circuit board on which a control circuit and a driving circuit are arranged, and the control circuit is connected to a microcontroller unit (MCU) that receives user commands, reads information, and controls the driving member 200 to execute corresponding start and stop commands.

[0090] In some embodiments, the electric supply unit 600 is electrically connected to each of the control unit 500 and the driving member 200. The electric supply unit 600 is for supplying power to the driving member 200 and the control unit 500. For example, the electric supply unit 600 is a lithium-ion battery, a nickel-metal hydride battery, an alkaline battery, etc.

[0091] When the stand 11 is used in an oral care scene, the user typically places the stand 11 on a bathroom sink. The bathroom environment is humid, and multiple electrical components are installed inside the stand 11. When the user installs or removes the stand 11 and squeeze bottle, moisture from the humidity is likely to enter the stand 11, causing problems such as a short circuit of the electrical components inside the stand 11.

[0092] In some embodiments, as shown in FIG. 5, a first waterproof sealing member 700 is installed outside the connecting shaft 410 to improve the waterproof performance of the stand 11.

[0093] For example, the first waterproof sealing member 700 is installed at the connecting portion of the connecting shaft 410 where the screw of the transmission squeezing structure is connected. The installation of the first waterproof sealing member 700 can improve the sealing performance of the connecting portion of the connecting shaft 410 where the screw of the transmission squeezing structure is connected, and can prevent water from entering the transmission member 320 and the driving member 200 from the connecting portion.

[0094] 8, a second waterproof sealing member 800 is further installed at the connection point between the elastic member 420 and the transmission structure 300. The installation of the second waterproof sealing member 800 can further prevent water from entering the stand 11 through the connection point between the elastic member 420 and the third transmission member 323.

[0095] In some embodiments, as shown in Figure 2, the stand body 100 is provided with a port 110, which is used for charging. When the power supply unit 600 in the stand 11 runs out of power, the user connects a cable to the port 110, turns on the power, and then charges the power supply unit 600. When the port 110 is not in use, it is covered with a silicone pad, and when the port 110 is in use, the silicone pad is removed to enable charging.

[0096] The type of the port 110 includes, but is not limited to, a USB port, a Type-C port, etc. By connecting to the port 110 via a cable, charging of the power module can be realized.

[0097] 5, a third waterproof sealing member 900 is installed on the port 110. The third waterproof sealing member 900 can prevent water from entering the stand 11 through the port 110 during charging, thereby preventing a short circuit.

[0098] As shown in Figures 4 and 9, in one embodiment, a switch 1200 and an insertion member 1300 are installed on the stand body 100, and the switch 1200 and the insertion member 1300 are electrically connected, and the insertion member 1300 is electrically connected to the control unit 500 and the power supply unit 600.

[0099] In some embodiments, the switch 1200 is one of a membrane switch, a photoelectric switch, and a push button switch. In this embodiment, the switch 1200 is a push button switch.

[0100] In some embodiments, the switch 1200 and the insert 1300 communicate with each other via a wired electrical connection to transmit the switch signal. In other embodiments, the switch 1200 and the insert 1300 communicate via wireless communication, which eliminates the need for wiring and attachment and simplifies the structure of the switch 1200.

[0101] As one embodiment of the first example, as shown in Figures 2 to 5, an extension section 120 is provided on the stand main body 100, a switch 1200 and an insertion member 1300 are installed on the extension section 120, and the switch 1200 is installed at the end of the extension section 120 close to the outlet of the squeeze container.

[0102] In this embodiment, when the stand 11 and the squeeze bottle are assembled, the extension 120 of the stand body 100 is located at the outlet of the squeeze bottle, and the switch 1200 is installed at the end of the extension 120 that is close to the outlet of the squeeze bottle. When a user uses the stand 11 and operates the switch 1200 to automatically squeeze out paste, the posture is closer to the natural posture of manually squeezing out paste, which is more ergonomic and easy for the user to hold, making the paste squeezing action smooth and easy, and the usage experience is closer to the daily habit of squeezing out toothpaste.

[0103] When a user performs oral care, their hands tend to get wet. When wet hands touch the switch 1200, water can easily enter the extension 120 through the gap in the switch 1200 and flow into the insertion member 1300, causing a short circuit. In view of this, in some embodiments, a fourth waterproof sealing member 1000 is installed in the extension 120 at the location where the switch 1200 is located. The fourth waterproof sealing member 1000 is installed along the gap at the connection point between the switch 1200 and the extension 120.

[0104] In the embodiment shown in Figure 9, the squeeze container is connected and attached to the stand body 100, so that the screw of the transmission squeeze structure in the squeeze container and the connecting member 400 on the stand body 100 are inserted into each other. When the user turns on the switch 1200, the switch 1200 and the insertion member 1300 are electrically connected. The control unit 500 sends a control command to the driving member 200 based on the signal from the user turning on the switch. The driving member 200 receives the command and drives the first transmission member 321 to rotate. The rotation of the first transmission member 321 drives the first sub-transmission member 3222 that engages with the first transmission member 321 to rotate. The rotation of the first sub-transmission member 3222 drives the two second sub-transmission members 3223 that are arranged on the same axis to rotate. The rotation of the two second sub-transmission members 3223 drives the two third transmission members 323 that engage with them to rotate. The rotation of the two third transmission members 323 rotates the connecting members 400 connected to the two third transmission members 323 together, and the rotation of the two connecting members 400 rotates the two screws in the transmission squeezing structure in the squeezing container, thereby driving the piston to advance along the extension direction of the screw axis, thereby realizing automatic squeezing of two different ingredient toothpastes.

[0105] 10, in the second embodiment, a mounting groove 130 is provided in the stand body 100, an elastic electrode 1320 is installed in the mounting groove 130, and a soft rubber 1330 is filled in the gap between the mounting groove 130 and the elastic electrode 1320 for sealing and waterproofing. The elastic electrode 1320 is electrically connected to the power supply unit 600. A switch 1200 and a metal insert block 1310 are installed in the squeeze container 22. When the stand 11 and the squeeze container 22 are assembled, the switch 1200 is electrically connected to the elastic electrode 1320 via the metal insert block 1310, thereby realizing signal transmission.

[0106] In this embodiment, a mounting groove 130 is provided on the housing of the stand body 100, an elastic electrode 1320 is mounted in the mounting groove 130, and soft rubber 1330 is poured into the mounting groove 130 to seal the gap between the elastic electrode 1320 and the stand body 100, thereby achieving a tight seal. The soft rubber 1330 also provides a certain degree of waterproofing.

[0107] Switch 1200 is exemplified by a membrane switch or a pushbutton switch, and elastic electrode 1320 is exemplified by a metal elastic piece. Metal insert block 1310 is installed at the rear end of squeeze container 22, and elastic electrode 1320 is installed inside, outside, or both inside and outside the housing of stand body 100. When squeeze container 22 and stand 11 are assembled and connected, metal insert block 1310 located at the rear end of squeeze container 22 and elastic electrode 1320 located at stand body 100 are connected to form a circuit, and elastic electrode 1320 is electrically connected to power supply unit 600. When a user turns on switch 1200 on squeeze container 22, switch 1200 is connected to metal insert block 1310 via wiring, and a switch signal is transmitted through wiring to metal insert block 1310, elastic electrode 1320, and power supply unit 600, thereby achieving circuit continuity.

[0108] 4, a fifth waterproof sealing member 1100 is installed on the bottom wall of the stand body 100. The stand body 100 is a housing structure for the stand 11, and a cover structure is usually used on the bottom of the stand body 100. Because the stand 11 is often placed in a humid environment such as a bathroom sink, in order to further prevent water from entering the stand body 100 through the cover on the bottom of the stand body 100, in this embodiment, the fifth waterproof sealing member 1100 is installed at the connection point between the stand and the cover of the stand body 100 to achieve waterproofing.

[0109] In the above embodiment, the first waterproof sealing member 700, the second waterproof sealing member 800, the third waterproof sealing member 900, the fourth waterproof sealing member 1000, and the fifth waterproof sealing member 1100 are one of rubber packings, sealing rings, O-rings, and X-rings. By installing a waterproof sealing member at each assembly port of the stand 11, it can be adapted to high-humidity environments such as bathrooms.

[0110] 4, a notification member 1400 is installed on the stand body 100, and the notification member 1400 is electrically connected to the control unit 500 and configured to notify information on the amount of electricity and operating status. The notification member 1400 is electrically connected to the control unit 500 and notifies information on the amount of electricity in the power source, operating status, etc.

[0111] In some embodiments, the notification element 1400 is a notification light, for example, an LED light.

[0112] After the switch 1200 is turned on, the control unit 500 on the one hand sends a control command to the driving member 200 to control it to operate, and then sends another control command to the notifying member 1400 to control it to notify the operating status of the stand 11. After the user stops turning on the switch 1200, the control unit 500 stops sending the control command to the driving member 200, at which time the driving member 200 stops operating, the automatic toothpaste dispensing action stops, and the notifying member 1400 turns off.

[0113] When the amount of electricity in the power supply unit 600 is insufficient, the notification member 1400 lights up abnormally and flashes intermittently to notify the user that the amount of electricity in the stand 11 is insufficient and that the stand 11 should be charged in a timely manner.

[0114] 1, 2 and 3, an engagement assembly 1500 is installed on stand body 100, and stand body 100 is removably connected to the squeeze container by engagement assembly 1500. In this embodiment, stand body 100 and the squeeze container are removably connected, so that when the toothpaste in the squeeze container runs out, the squeeze container can be removed from stand 11 and replaced with a new squeeze container, allowing stand 11 to be used continuously.

[0115] In some embodiments, as shown in FIG. 3, the engagement assembly 1500 includes an engagement block 1510 and an elastic spacer 1520, the engagement block 1510 is connected to the stand body 100 by the elastic spacer 1520, an engagement opening is provided on the squeeze container, and the squeeze container is engaged with the engagement block 1510 through the engagement opening.

[0116] The engagement assembly 1500 has a G-shape rotated 90 degrees. Because the internal space of the engagement block 1510 is narrow and the engagement block 1510 receives force in only one direction, the shape of the engagement block 1510 is unbalanced and tends to assume a roughly "eight" shape, making it difficult to remove by pressing the engagement block 1510. In view of this, in this embodiment, an elastic spacer 1520 structure is installed inside the button of the engagement block 1510. The force-receiving surface of the elastic spacer 1520 is larger than the force-receiving surface of the spring. Therefore, when the user presses the engagement block 1510, the engagement block 1510 is less likely to collapse and is easier to remove. The elastic spacer 1520 may be made of rubber.

[0117] In order to facilitate the connection between the stand 11 and the squeeze container, in this embodiment, two engagement blocks 1510 are provided, and the two engagement blocks 1510 are provided symmetrically on the stand body 100, and two engagement ports for the squeeze container are also provided.

[0118] During a certain operation, the screw of the transmission squeezing structure of the squeeze container is aligned with the connecting member 400 in the stand 11, and the engagement block 1510 of the stand body 100 is engaged with the engagement opening of the squeeze container, at which point the screw of the transmission squeezing structure is connected to the connecting member 400 in the stand 11, and the stand 11 and the squeeze container are positioned and connected. When the user wants to remove the stand 11, they hold the stand with one hand and press the engagement block 1510 to release it from the engagement opening, and then pull the squeeze container out of the stand 11 to achieve removal.

[0119] As described above, the stand 11 of the present invention is configured to be assembled and attached to the squeezing container separately by installing the connecting member 400, thereby allowing the stand 11 to be used continuously, realizing automatic squeezing of one or more ingredients with different compositions, and improving the work efficiency when the stand 11 automatically squeezes ingredients.

[0120] As shown in Figures 11, 12 and 13, the present invention provides an electric squeezing device 1. The electric squeezing device 1 includes a stand 11 and a squeezing container 22. When the stand 11 and the squeezing container 22 are assembled, a transmission structure 300 is connected to the transmission squeezing structure 220 of the squeezing container 22.

[0121] As described above, the stand 11 is removably assembled with the squeeze container 22. When assembling the stand 11 and the squeeze container 22, the screw of the transmission squeeze structure in the squeeze container and the connecting member 400 on the stand main body 100 are inserted into each other. The engagement block 1510 on the stand main body 100 is engaged with the engagement opening on the squeeze container, and the stand 11 and the squeeze container are positioned and connected. When the user turns on the switch 1200, the switch 1200 and the insertion member 1300 become conductive, and the control unit 500 sends a control command to the driving member 200 based on the signal from the user turning on the switch, and the driving member 200 receives the command and rotates the first transmission member 321, and the rotation of the first transmission member 321 rotates the first sub-transmission member 3222 that meshes with the first transmission member 321, and the rotation of the first sub-transmission member 3222 rotates the two second sub-transmission members 3223 that are installed coaxially, and the rotation of the two second sub-transmission members 3223 rotates the two third transmission members 323 that mesh with them, respectively. The rotation of the two third transmission members 323 rotates the connecting members 400 connected to the two third transmission members 323 together, and the rotation of the two connecting members 400 rotates the two screws in the transmission squeezing structure inside the squeezing container, thereby driving the piston to advance along the extension direction of the screw axis, thereby realizing automatic squeezing of two different ingredient toothpastes.

[0122] After the switch 1200 is turned on, the control unit 500 on the one hand sends a control command to the driving member 200 to control it to operate, and then sends another control command to the notifying member 1400 to control it to notify the operating status of the stand 11. After the user stops turning on the switch 1200, the control unit 500 stops sending the control command to the driving member 200, at which time the driving member 200 stops operating, the automatic toothpaste dispensing action stops, and the notifying member 1400 turns off.

[0123] As described above, the electric squeezing device 1 of the present invention can be used in applications such as oral care, beauty and personal care, medicine, industrial construction, etc. The electric squeezing device 1 of the present invention can realize automatic squeezing of a single ingredient in the squeezing container 22, and can also realize automatic synchronous squeezing of multiple ingredients in the squeezing container 22.

[0124] The above embodiments are only for illustrating the technical solution of the present invention and are not intended to limit the present invention. Those skilled in the art may have various modifications and variations to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention are within the scope of protection of the present invention.
