Description

Technical Field

[0001] The present application relates to the technical field of extrusion container-related equipment, and in particular, to an extrusion container and an electric extrusion device. Background Art

[0002] Existing electric extruders consist of a tube structure and a gland structure, which are connected to each other. The tube structure houses a chamber for accommodating materials. A piston and screw assembly are located within the chamber, while the gland structure houses a reduction motor, battery, control circuit board, and other components. The reduction motor powers the screw via a planetary gear transmission. The rotation of the screw drives the piston in linear motion, achieving simultaneous extrusion of one or more materials from the tube structure.

[0003] Since a planetary gear transmission structure is installed at the connection between the tail of the tube structure and the gland structure to drive the screw assembly and the piston, when the screw rotates to push the piston to perform linear motion, the material can easily flow through the piston and the screw into the planetary gear transmission structure, as well as the battery and control circuit board in the gland structure, causing contamination of the various components in the gland structure, easily causing the electric extrusion container to malfunction, thereby reducing the working efficiency of the electric extrusion container. Utility Model Content

[0015] In one embodiment, a limiting protrusion rib is provided in the shaft sleeve mounting portion, and a portion of the transmission member located in the shaft sleeve mounting portion is provided with a limiting groove that cooperates with the limiting protrusion rib.

DETAILED DESCRIPTION

[0103] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0104] Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and should not be understood as indicating or implying relative importance.

[0105] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, a schematic structural diagram of an extrusion container 10 provided in the present application. An extrusion container 10 comprises: a container body 100, a cover plate 200, a connecting structure 300, and a transmission extrusion structure 400; the container body 100 is provided with a chamber 110 for accommodating materials, and the container body 100 is provided with an outlet 120, which is in communication with the chamber 110; the cover plate 200 is detachably connected to the rear end of the container body 100 via the connecting structure 300, and is used to seal the container body 100; the transmission extrusion structure 400 is provided in the container body 100, and is movably connected to the cover plate 200, and is used to extrude the material in the chamber 110 from the outlet 120.

[0106] In this embodiment, the material is stored in the chamber 110 within the extrusion container 10, and the material within the chamber 110 is sealed by connecting the cover plate 200 to the rear end of the extrusion container 10. By providing a transmission extrusion structure 400 for extruding the material within the container body 100, and relying on the movable connection between the cover plate 200 and the transmission extrusion structure 400, the cover plate 200 can play a role in positioning and supporting the transmission extrusion structure 400 during the process of extruding the material toward the outlet 120, thereby enabling the transmission extrusion structure 400 to extrude the material from the outlet 120 more automatically, stably, and efficiently. Due to the sealing effect of the cover plate 200, the problem of material leakage from the chamber 110 when the transmission extrusion structure 400 is extruding the material can be improved, thereby reducing the risk of failure of the extrusion container 10 and improving the working efficiency of the extrusion container 10 in extruding the material.

[0107] In order to facilitate the filling of materials into the chamber 110, the rear end of the container body 100 and the cover plate 200 can be detachably connected via a connecting structure 300. During one operation, the material is poured into the chamber 110 from the rear end of the container body 100, and a certain distance is left between the material liquid level and the rear end of the container body 100. This can prevent the material from being squeezed by the transmission extrusion structure 400 and overflowing when the chamber 110 is filled with material and then the transmission extrusion structure 400 and the cover plate 200 are installed, causing waste and pollution. Next, the transmission extrusion structure 400 is first installed on the cover plate 200, and the transmission extrusion structure 400 is inserted into the chamber 110 that has been filled with material. Finally, the cover plate 200 is pushed into the container body 100 and installed with the rear end of the container body 100 via the connecting structure 300, thereby completing the positioning and fixation of the cover plate 200.

[0108] In some embodiments, once the material within the container body 100 is exhausted, the cover plate 200 can be removed from the container body 100 via the connection structure 300, and the same type or composition of material can be continuously poured into the chamber 110 of the container body 100. In such cases, the extrusion container 10 can be reused, typically primarily for production cost considerations. For environmental and hygienic reasons, the extrusion container 10 can be used as a disposable consumable, meaning that once the material within the container body 100 is exhausted, the extrusion container 10 is no longer reused.

[0109] In some embodiments, the container body 100 can be a cylindrical, regular tubular structure, or an irregular tubular structure such as an elliptical cylinder. Accordingly, the cover plate 200 seals the container body 100, and the shape of the cover plate 200 should be consistent with the shape of the container body 100.

[0110] In some embodiments, the container body 100 may be made of polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate glycol (PETG), polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), thermoplastic polyurethane (TPU), etc. The container body 100 may be manufactured using different materials according to actual production needs.

[0111] In some embodiments, the extrusion container 10 can be used in scenarios such as oral care, beauty and personal care, medicine, and industrial construction.

[0112] As an example, in the application scenario of oral care, the material contained in the cavity 110 of the container body 100 of the extrusion container 10 can be toothpaste paste, toothpaste powder, oral care liquid, etc. The toothpaste paste, toothpaste powder, and oral care liquid can be automatically squeezed out through the transmission extrusion structure 400, which is convenient for users to perform oral care.

[0113] In the application scenario of beauty and personal care, the materials contained in the chamber 110 of the container body 100 can be skin care water, essence, lotion, face cream, facial cleanser, paste-like facial mask, etc. The skin care water, essence, lotion, face cream, facial cleanser, paste-like facial mask can be automatically squeezed out through the transmission extrusion structure 400, which is convenient for users to perform skin care.

[0114] In medical application scenarios, the materials contained in the chamber 110 of the container body 100 can be disinfectants (such as alcohol, hydrogen peroxide, etc.), liquid medicine, paste medicine, powder medicine, etc. The disinfectant solution, liquid medicine, paste medicine, and powder medicine can be automatically squeezed out through the transmission extrusion structure 400, making it convenient for users to provide medical care.

[0115] In the application scenario of industrial buildings, the materials contained in the chamber 110 of the container body 100 can be cement, lime paste, lime, etc., which can be automatically squeezed out through the transmission extrusion structure 400, making it convenient for construction workers to carry out construction work.

[0116] For the convenience of description, the extrusion container 10 of the present application is taken as an example for application in an oral care scenario, and the materials described below are described using toothpaste paste as an example.

[0117] In some embodiments, the cross-sectional dimension of the container body 100 gradually decreases from the tail end of the container body 100 to the outlet 120 end of the container body 100. When the cross-sectional dimension of the container body 100 gradually decreases from the tail end to the outlet 120 end, this means that the volume of the toothpaste paste squeezed out each time is reduced. By adjusting the cross-sectional dimension at the outlet 120 to gradually decrease, the amount of toothpaste used each time can be controlled to avoid waste and ensure that the user can control the amount used. This design not only takes into account the complex ingredients of toothpaste and the user's usage habits, ensuring that the user can better control the amount used each time, but also avoids the problem of waste caused by excessive use. In addition, this design also takes into account the quality of the toothpaste. By reducing the amount used each time, quality problems caused by the contact of toothpaste with air can be reduced, thereby maintaining the freshness and effectiveness of the toothpaste.

[0118] Please refer to Figure 3 In the first embodiment shown, the chamber 110 in the container body 100 is set as one, and correspondingly, a transmission extrusion structure 400 can be set in the chamber 110. Therefore, Figure 3 The extrusion container 10 shown in the embodiment can realize the automatic extrusion of a material of one component, that is, the automatic extrusion of a toothpaste paste of one component.

[0119] In other embodiments, please refer to Figure 4 、 Figure 5 As shown, the container body 100 further includes: a partition 130 ; the partition 130 is disposed in the chamber 110 , and the partition 130 is used to separate the chamber 110 into a plurality of sub-chambers 111 along the extension direction of the container body 100 , and the sub-chambers 111 are connected to the outlet 120 .

[0120] In this embodiment, the partition 130 is provided in the chamber 110 and connected to the container body 100. The partition 130 is used to separate the chamber 110 into a plurality of sub-chambers 111 along the extension direction of the container body 100. As an example, Figure 5As shown, a single partition 130 is provided, dividing the interior space of chamber 110 into two along the extension direction of container body 100, forming two sub-chambers 111 of equal volume. The two sub-chambers 111 can be filled with toothpaste of different compositions or toothpaste of the same composition. Furthermore, each sub-chamber 111 is connected to outlet 120. The transmission extrusion structure 400 can synchronously drive the toothpaste in the two sub-chambers 111 to achieve simultaneous extrusion of the two toothpastes of different compositions, enabling the toothpaste to be mixed and used immediately.

[0121] In some other embodiments, please refer to Figure 6 As shown, there are three partitions 130, which can be integrally formed or glued together. The three partitions 130 divide the internal space of the chamber 110 into three along the extension direction of the container body 100, forming three sub-chambers 111 of equal volume. The three sub-chambers 111 can be filled with toothpaste of different ingredients or toothpaste of the same ingredients, and all three sub-chambers 111 are connected to the outlet 120. An independent transmission extrusion structure 400 is set in each sub-chamber 111 to realize the automatic extrusion of the material in each sub-chamber 111. The transmission extrusion structure 400 in each sub-chamber 111 can be driven by a separate drive structure. Therefore, it can be understood that different numbers of partitions 130 can be set in the extrusion container 10 according to the use requirements of toothpaste of different ingredients to divide the chamber 110 into more sub-chambers 111, for example, into four sub-chambers 111 or even more sub-chambers 111.

[0122] exist Figure 3 、 Figure 4 、 Figure 6 It can be seen from the structure of the extrusion container shown in the embodiment that the container body 100 is configured as a single tube structure, that is, the container body 100 is configured as one.

[0123] In other embodiments, the container body 100 may be provided in plurality, and each container body 100 is connected to each other to form an extrusion container 10 for extruding different materials.

[0124] In this embodiment, as an implementation method, a chamber 110 can be set in each container body 100, and a transmission extrusion structure 400 is set in each chamber. The transmission extrusion structure 400 is movably connected to the cover plate 200, and then the cover plate 200 is installed together with the extrusion container 10. Each extrusion container 10 can drive the transmission extrusion structure 400 to extrude the toothpaste paste through its own independent driving structure, or a driving structure can be used to synchronously drive the transmission extrusion structures 400 in three extrusion containers 10 to extrude the toothpaste paste, so that the toothpaste paste can be mixed and used immediately.

[0125] Then, two or three container bodies 100 of the same structure as described in the above embodiment are connected, for example, adjacent container bodies 100 can be glued together or fixed together by screws, to finally form an integrated extrusion container 10. The extrusion container 10 with such a structure can be used to extrude two or three toothpastes with different ingredients, so that the toothpaste can be mixed and used immediately.

[0126] In some embodiments, as Figure 4 As shown, one end of the partition 130 extends to the outlet 120, and the other end of the partition 130 abuts against the cover plate 200. One end of the cover plate 200 extends toward the outlet 120, and is connected to the wall surface of the outlet 120 of the container body 100 at the outlet 120. The other end of the cover plate 200 extends toward the tail of the container body 100, and abuts against the cover plate 200 connected to the tail of the container body 100. The abutment between the cover plate 200 and the partition 130 plays a role in installation and positioning. Through the arrangement of the partition 130 and the interaction force of the connecting structure 300 in two directions on the side wall of the container body 100, sufficient supporting force is given to the transmission extrusion structure 400, further strengthening the stability of the connection between the partition 130 and the container body 100, so that the transmission extrusion structure 400 can extrude the material from the outlet 120 more automatically, stably and efficiently.

[0127] by Figure 4 As shown in the embodiment, the container body 100 is divided into two parts by a partition 130, and the container body 100 is an elliptical tubular structure. Figure 5 、 Figure 7 、 Figure 8 and Figure 9 As shown, the structure of the cover plate 200 is consistent with the shape of the container body 100, and is an elliptical structure with uniform thickness.

[0128] In some embodiments, the material of the cover 200 can be consistent with the material of the container body 100. For example, the material of the cover 200 is polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonate (PC), polyethylene terephthalate glycol (PETG), polylactic acid (PLA), etc.

[0129] Please refer to Figure 3 、 Figure 4 As shown, the connection structure 300 is connected to the cover plate 200 , and the connection structure 300 is clamped with the container body 100 .

[0130] In some embodiments, please refer to Figure 2 、 Figure 11 As shown, the container body 100 is provided with a snap-in 112. As an example, the snap-in 112 can be a slot or a hole provided on the container body 100.

[0131] Please refer to Figure 11 FIG. 3 is a diagram showing a connection structure provided in the first embodiment of the present application. The connection structure 300 includes a latch 310 , one end of which is disposed on the cover 200 , and the other end of which is engaged with the latch 112 .

[0132] As an example, the latch 310 can be a protrusion integrally formed on the cover plate 200, and the protrusion can be snapped into the latch 112. In order to facilitate the connection between the cover plate 200 and the container body 100, in this embodiment, two latches 310 can be provided, and symmetrically arranged at the two ends of the cover plate 200. Correspondingly, the latch 112 on the container body 100 is also provided with two. In other embodiments, more than two, or multiple latches 310 can be provided on the cover plate 200 according to specific design requirements. It should be noted that the number of latches 112 on the container body 100 should be consistent with the number of latches 310.

[0133] In this embodiment, the container body 100 and the connecting structure 300 can be connected by a snap-fit connection. This snap-fit connection facilitates the removal of the container body 100 from the cover plate 200 and is easy to operate. By pushing the cover plate 200 into the container body 100, the snap-fit member 310 on the cover plate 200 snaps into the snap-fit opening 112 of the container body 100, thereby securing the cover plate 200 to the wall of the chamber 110 of the container body 100. When the snap-fit member 310 snaps into the snap-fit opening 112 of the container body 100, the cover plate 200 and the container body 100 are positioned and fixed.

[0134] In some embodiments, the connection structure 300 further includes positioning ribs 320 disposed on one end of the latch 310 that engages the latch 112. The positioning ribs 320 enhance the connection stability between the latch 310 and the latch 112. When the user needs to disassemble the container body 100 and the cover 200, they can grasp the positioning ribs 320 on the latch 310 on both sides of the cover 200 with one hand and press the positioning ribs 320 to disengage the positioning ribs 320 from the latch 112, facilitating disassembly.

[0135] Furthermore, the latch 310 bends in the direction of extension of the container body 100 to form a curved arc structure 311. A positioning rib 320 is provided on the latch 310 at one end, away from the arc structure 311, and is engaged with the latch 112. In this embodiment, the latch 310 is a resilient, arc-shaped member. When the user needs to disassemble the container body 100 and the cover 200, they can grasp the positioning ribs 320 on both sides of the latch 310 with one hand and press the positioning ribs 320. Due to the elasticity of the latch 310, the latch 310 can be quickly disengaged from the latch 112, making disassembly more convenient.

[0136] Please refer to Figures 12(a), 12(b), and 12(c), which illustrate a connection structure provided in a second embodiment of the present application. A first mounting hole 113 is provided on the container body 100, and a second mounting hole 230 is provided on the cover plate 200. The connection structure 300 includes a first connector 330, which passes through the first mounting hole 113 and the second mounting hole 230, respectively, to connect the cover plate 200 to the container body 100.

[0137] In some embodiments, the first connecting member 330 can be a screw, wherein a threaded structure is provided in the first mounting hole 113, and a threaded structure is provided in the second mounting hole 230. The screw passes through the first mounting hole 113 and the second mounting hole 230 in sequence to threadably connect and fix the cover plate 200 to the container body 100.

[0138] In some other embodiments, the first connecting member 330 may be a pin, which passes through the first mounting hole 113 and the second mounting hole 230 in sequence to fasten the cover plate 200 to the container body 100 .

[0139] In the above two embodiments, the connection structure 300 has a simple structure, is easy for the user to operate, and has a simpler connection method.

[0140] Please refer to Figures 13(a), 13(b), and 13(c), which illustrate a connection structure provided in a third embodiment of this application. Connection structure 300 includes a first connection portion 340 and a second connection portion 350. The first connection portion 340 is disposed on the container body 100, and the second connection portion 350 is disposed on the cover plate 200. The first connection portion 340 and the second connection portion 350 are threadedly connected. This embodiment of connection structure 300 is simpler in structure and more convenient for users to operate.

[0141] In some embodiments, the first connection portion 340 is disposed on the inner wall of the chamber 110 of the container body 100; the second connection portion 350 is disposed on one end of the cover plate 200 adjacent to the inner wall of the chamber 110 of the container body 100. In this embodiment, the container body 100 may be a cylindrical tubular structure, and the cover plate 200 may be a circular cover plate structure. The second connection portion 350 is disposed on the circumferential edge of the cover plate 200 along the thickness direction, and the first connection portion 340 is disposed along the circumference of the inner wall of the chamber 110 of the container body 100. During installation, the first connection portion 340 and the second connection portion 350 engage and dock to achieve connection between the container body 100 and the cover plate 200.

[0142] Please refer to Figures 14(a), 14(b), and 14(c), which illustrate a connection structure provided in a third embodiment of the present application. The cover plate 200 further includes a mounting portion 240, which extends from the cover plate 200 outside the container body 100 and is at least partially located outside the sidewall of the container body 100. A first connecting portion 340 is located on the outside of the sidewall of the container body 100, and a second connecting portion 350 is located on the portion of the mounting portion 240 located outside the sidewall of the container body 100.

[0143] In this embodiment, the container body 100 can be a cylindrical tubular structure, and accordingly, the cover plate 200 is a circular cover plate structure. A mounting portion 240 is provided on the circumferential edge of the cover plate 200 along the thickness direction. When the cover plate 200 is installed with the container body 100, the mounting portion 240 is extended out of the container body 100, and a portion of the mounting portion 240 is exposed on the outside of the side wall of the container body 100, so that when the first connecting portion 340 and the second connecting portion 350 are docked, a portion of the mounting portion 240 can support the outer wall of the container body 100, thereby realizing the connection between the cover plate 200 and the container body 100 from the outside of the side wall of the container body 100.

[0144] In the embodiments shown in Figures 13(b) and 14(b), as one embodiment, the first connecting portion 340 is provided with an internal thread structure, and the second connecting portion 350 is provided with an external thread structure. As another embodiment, the first connecting portion 340 is provided with an external thread structure, and the second connecting portion 350 is provided with an internal thread structure. In both embodiments, the first connecting portion 340 and the second connecting portion 350 are connected by a threaded connection, which facilitates installation and removal.

[0145] As an example, in Figure 13(b), when positioning and installing the container body 100 and the cover plate 200, the cover plate 200 is pushed into the container body 100 to make the first connection part 340 and the second connection part 350 docked, and then by holding the cover plate 200 and rotating the container body 100 at the same time, the first connection part 340 on the inner wall of the chamber 110 of the container body 100 and the second connection part 350 on the cover plate 200 are threadedly connected, thereby realizing the installation connection between the container body 100 and the cover plate 200, which is more convenient and simple to operate.

[0146] As an example, in Figure 14(b), when positioning and installing the container body 100 and the cover plate 200, the cover plate 200 is pushed into the container body 100, and the mounting portion 240 is exposed outside the container body 100, so that the mounting portion 240 partially supports the outer side of the side wall of the container body 100, and then by holding the mounting portion 240 and rotating the container body 100, or holding the container body 100 and rotating the mounting portion 240, the second connecting portion 350 on the mounting portion 240 is threadedly connected to the first connecting portion 340 on the outer side wall of the container body 100, thereby realizing the installation connection between the container body 100 and the cover plate 200, and the operation is more convenient and simple.

[0147] Please refer to Figure 15 , which is a schematic diagram of a transmission extrusion structure provided in one embodiment of the present application. The transmission extrusion structure 400 includes: a transmission member 410 and a piston 420. One end of the transmission member 410 is movably connected to the cover plate 200. The transmission member 410 is disposed within the chamber 110 along the extension direction of the container body 100. The piston 420 is in transmission connection with the transmission member 410. The transmission member 410 drives the piston 420 forward or backward along the extension direction of the axis of the transmission member 410 to achieve material extrusion.

[0148] In this embodiment, the piston 420 can be driven forward or backward along the axial extension direction of the transmission member 410 by the forward and reverse transmission of the transmission member 410 in the transmission extrusion structure 400, thereby realizing the automatic extrusion of the material in the chamber 110 by the piston 420.

[0149] by Figure 4 Taking the structure of the extrusion container 10 shown as an example, a partition 130 is provided in the container body 100, dividing the chamber 110 of the container body 100 into two independent sub-chambers 111, each of which is used to accommodate toothpaste pastes of different components. In order to achieve the automatic and synchronous extrusion of the toothpaste pastes in the two sub-chambers 111 and achieve the purpose of mixing and using, the transmission extrusion structure 400 in this embodiment includes two transmission members 410 and two pistons 420. A transmission member 410 and a piston 420 are respectively provided in each sub-chamber 111. The two transmission members 410 can rotate synchronously, thereby driving the two pistons 420 to achieve synchronous forward or backward movement, ultimately achieving the automatic and synchronous extrusion of the toothpaste pastes of different components in the two sub-chambers 111.

[0150] Further, please combine Figure 7 、 Figure 9 、 Figure 10 As shown, the cover plate 200 is provided with a through hole 210, and the through hole 210 is provided with a shaft sleeve mounting portion 220; please refer to Figure 4As shown, the transmission member 410 passes through the through hole 210 and is rotatably connected to the sleeve mounting portion 220. In this embodiment, since there are two transmission members 410, there are correspondingly two through holes 210 on the cover plate 200. Since the cover plate 200 is fixedly connected to the container body 100, and the transmission member 410 transmits power by rotation, the transmission extrusion structure 400 and the cover plate 200 are movably connected. Specifically, the transmission member 410 passes through the through hole 210 on the cover plate 200 and penetrates the cover plate 200. The setting of the sleeve mounting portion 220 enables the transmission member 410 to be installed on the cover plate 200 while also transmitting power to the piston 420 to drive the piston 420 forward or backward.

[0151] In some embodiments, please refer to Figure 9 、 Figure 10 As shown, the sleeve mounting portion 220 is provided with a limiting protrusion rib 221, please refer to Figure 16 、 Figure 17 As shown, the portion of the transmission member 410 located within the shaft sleeve mounting portion 220 is provided with a limiting groove 411 that cooperates with the limiting protruding rib 221 .

[0152] In this embodiment, a circle of limiting protrusions 221 is provided on the inner side of the sleeve mounting portion 220, and correspondingly, a circle of limiting grooves 411 is provided on the transmission member 410. The cooperation between the limiting protrusions 221 and the limiting grooves 411 ensures that the transmission member 410 is relatively firmly connected to the sleeve mounting portion 220 when transmitting power to the piston 420, reducing the risk of the transmission member 410 slipping.

[0153] For further information, please refer to Figure 10 As shown, the sleeve mounting portion 220 is provided with a slot 222 along the axis of the transmission member 410. The slot 222 of a certain width is cut into the sleeve mounting portion 220 in the radial direction along the axis of the transmission member 410. The provision of the slot 222 provides the sleeve mounting portion 220 with a certain degree of flexibility, facilitating the installation of the transmission member 410. The transmission member 410 can also be movably connected to the cover plate 200 by the cooperation between the limiting protrusion rib 221 and the limiting groove 411.

[0154] In some embodiments, please refer to Figure 16 As shown, the transmission member 410 is mounted on the shaft sleeve mounting portion 220 and has a male connector 412 at one end extending out of the cover plate 200. The male connector 412 is used to connect to the driving structure.

[0155] In other embodiments, please refer to Figure 17 As shown, the transmission member 410 is mounted on the shaft sleeve mounting portion 220 and has a female connector 413 at one end extending out of the cover plate 200. The female connector 413 is used to connect to the driving structure.

[0156] As an embodiment, the driving structure can be a driving motor for driving the transmission extrusion structure 400. The output end of the driving motor can be connected to the transmission member 410 of the transmission extrusion structure 400 through a docking component. The power source is transmitted to the transmission member 410 through the driving structure, and the transmission member 410 transmits power to the piston 420 to drive the piston 420 forward or backward.

[0157] exist Figure 16 In the embodiment shown, the shaft head of the transmission member 410 is a male joint portion of an outer polygonal boss, so the docking component on the drive structure for connecting with the transmission member 410 can be provided with a female joint portion of an inner concave polygonal sleeve. Figure 17 In the embodiment shown, the shaft head of the transmission member 410 is a female joint portion of an inwardly concave polygonal sleeve, and a male joint portion of an outer polygonal boss can be provided on the docking component on the drive structure for connecting with the transmission member 410.

[0158] In the above two embodiments, the cross section of the male connector 412 or the female connector 413 is set to be a circle or a polygon. Figure 18 As shown, when the cross-section of the male connector portion 412 or the female connector portion 413 is provided with a polygonal structure, the transmission member 410 can be prevented from rotating and slipping on the cover plate 200 and facilitates the rapid alignment and connection between the transmission member 410 and the driving structure.

[0159] For further information, please refer to Figure 15 As shown, the transmission member 410 is threadedly connected to the piston 420; the transmission member 410 is provided with an external thread structure, and the piston 420 is provided with an internal thread structure; or, the transmission member 410 is provided with an internal thread structure, and the piston 420 is provided with an external thread structure.

[0160] In one embodiment, the transmission member 410 can be a screw or lead screw, with a threaded structure provided on the transmission member 410. The piston 420 has a threaded hole, which is also provided with a threaded structure. The transmission member 410 passes through the threaded hole of the piston 420 and is threadedly connected to the piston 420. The piston 420 can move along the axial extension direction of the transmission member 410 without rotating in place. When the drive structure drives the transmission member 410 to rotate, the rotation of the transmission member 410 drives the piston 420 to move forward or backward in the axial extension direction of the transmission member 410, thereby squeezing out or sucking the toothpaste paste back into the chamber 110.

[0161] As some other embodiments, the transmission extrusion structure 400 may be an electric push rod, and a piston 420 is provided at the end of the electric push rod. The piston 420 is pushed forward by the electric push rod to realize automatic extrusion of the toothpaste paste.

[0162] As another embodiment, the transmission extrusion structure 400 can be driven by a cylinder, and a pushing component is provided on the piston rod of the cylinder. Figure 15 The piston 420 in the cylinder has the same function, which is to realize the toothpaste paste. The piston is used to move back and forth in a straight line in the cylinder to drive the pushing component forward or backward to realize the extrusion or suction of the toothpaste paste.

[0163] Please refer to Figure 19 As shown, piston 420 comprises a piston body 421 and a skirt 422. Skirt 422 is disposed on piston body 421 and is inclined toward the inner wall of chamber 110. The thickness of skirt 422 can be adjusted based on the material, ensuring that skirt 422 maintains a reasonable degree of elasticity. The configuration of skirt 422 ensures a good seal between piston 420 and the inner wall of chamber 110 while also ensuring the flexibility of piston 420's movement.

[0164] Furthermore, the end of the piston body 421 away from the cover plate 200 protrudes in the direction of the axis of the transmission member 410 to form a raised portion 4211, and the shape of the raised portion 4211 matches the shape of the inner wall of the container body 100 near the outlet 120. The shape of the sub-chamber 111 separated by the piston body 421 and the partition 130 is similar to that of a non-circular irregular shape. The raised portion 4211 formed by the end of the piston body 421 away from the cover plate 200 protruding in the direction of the axis of the transmission member 410 matches the shape of the front inner wall of the container body 100 near the outlet 120. When the piston 420 is pushed to the front end of the outlet 120 of the container body 100, the toothpaste paste in the sub-chamber 111 can be squeezed out to the greatest extent, thereby reducing the waste of toothpaste paste.

[0165] In some embodiments, the outermost dimension of the inclined skirt 422 is larger than the dimension of the inner wall of the chamber 110. The skirt 422 is inclined outward at a certain angle to the piston 420, and the outermost dimension of the skirt 422 is larger than the inner dimension of the chamber 110 of the container body 100. This design ensures a good seal between the piston 420 and the inner wall of the chamber 110. When the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 is pressed against the skirt 422 by pressure. Under the action of pressure, the skirt 422 and the inner wall of the chamber 110 are more closely attached, thereby allowing the piston 420 to seal the chamber 110.

[0166] As an embodiment, the skirt 422 includes: a first skirt 4221 and a second skirt 4222, the first skirt 4221 is arranged on the end of the piston body 421 away from the cover plate 200, and the second skirt 4222 is arranged on the end of the piston body 421 close to the cover plate 200.

[0167] In this embodiment, when the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 is subjected to pressure to squeeze the first skirt 4221 and the second skirt 4222. Under the action of the pressure, the first skirt 4221 and the second skirt 4222 are more closely attached to the inner wall of the chamber 110, so that the piston 420 acts to seal the chamber 110. At the same time, when the piston 420 moves backward, the second skirt 4222 also contacts the inner wall of the chamber 110, acting as a seal and improving the stability of the piston 420.

[0168] As another embodiment, please refer to Figure 20(a) and Figure 20(b), the skirt 422 also includes: a third skirt 4223, the third skirt 4223 is provided on the piston body 421 and is located between the first skirt 4221 and the third skirt 4223.

[0169] In this embodiment, the third skirt 4223 can be provided on the piston body 421 and between the first skirt 4221 and the second skirt 4222, and can be closer to the first skirt 4221. The third skirt 4223 can be a skirt structure formed along the circumference of the piston body 421 and protruding toward the inner wall of the chamber 110.

[0170] When the transmission member 410 drives the piston 420 forward to squeeze out the toothpaste, the piston 420 is subjected to pressure, squeezing the first skirt 4221 and the second skirt 4222. Under the action of pressure, the first skirt 4221 and the second skirt 4222 are more closely attached to the inner wall of the chamber 110. As the transmission member 410 continues to drive the piston 420 forward, the first skirt 4221 is subjected to pressure, and the seal may fail to seal the toothpaste. In this case, the toothpaste is likely to overflow along the gap between the first skirt 4221 and the inner wall of the chamber 110 toward the rear of the container body 100. Because the third skirt 4223 is disposed between the first skirt 4221 and the second skirt 4222, when the overflowing paste flows along the gap between the first skirt 4221 and the inner wall of the chamber 110 toward the rear end of the container body 100, it will first overflow toward the third skirt 4223. The third skirt 4223 blocks the paste, preventing it from continuing toward the second skirt 4222 or even overflowing onto the partition 130. Therefore, in this embodiment, the provision of the third skirt 4223 further improves the sealing performance of the piston 420.

[0171] Therefore, when the transmission extrusion structure 400 is extruding toothpaste, the rotation of the two transmission members 410 drives the pistons 420 connected to each transmission member 410 to move forward synchronously along the axial extension direction of the transmission member 410. When the drive structure driving the transmission extrusion structure 400 outputs driving force at a uniform speed, the drive structure drives the two transmission members 410 to propel the two pistons 420 forward at a uniform speed, thereby ensuring that the amount of extruded toothpaste is controllable.

[0172] Please refer to Figure 21 As shown, a switch 500 is provided on the container body 100, and a plug-in component 600 is provided on the container body 100. The switch 500 is electrically connected to the plug-in component 600, and the plug-in component 600 is used to electrically connect with the conductive component on the base installed in conjunction with the extrusion container 10 to transmit electrical signals.

[0173] In this embodiment, a control module, a power module, and a drive structure can be provided in the base. By providing an electrically connected switch 500 and a plug-in component 600 on the container body 100, the plug-in component 600 is electrically connected to the control module and the power module. The base provided with a conductive component is docked and installed with the extrusion container 10.
