Description

Technical Field

[0001] The utility model relates to a toothpaste extruder, in particular to a toothpaste extruder which is easy to clean. Background Art

[0002] The current toothpaste is encapsulated in a plastic, pressable and deformable toothpaste packaging tube. Every time it is used, it is necessary to squeeze the toothpaste tube by hand to squeeze the toothpaste onto the toothbrush. With the popularization of smart home life, some smart toothpaste extruders have gradually emerged. At present, smart toothpaste extruders generally use an extrusion pump to use the vacuum compression principle to control the amount of toothpaste extruded according to the pushing depth of the extrusion button to complete the action of squeezing toothpaste. However, this method generally leaves residues at the outlet of the extrusion pump. The residual toothpaste here hardens in contact with the external air, resulting in a hard head phenomenon, which is not conducive to the next toothpaste extrusion, and is inconvenient to clean. Once cleaned, it needs to be completely disassembled. In order to solve the above-mentioned residual problem, the prior art patent CN211811055U has appeared to disclose a toothpaste extrusion device, which uses two rollers to place the toothpaste tube between the two rollers. The rollers roll to drive the toothpaste tube to move up and squeeze the internal toothpaste out of the toothpaste tube mouth. This technology can solve the problem of residues, but the above technology is also prone to the situation where the rollers are squeezed and stuck or damaged. The toothpaste tube is subject to certain restrictions. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0021] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] like Figure 1-6 As shown, a toothpaste squeezer that is easy to clean includes a shell 1. In order to facilitate fixation, the shell 1 is in a rectangular shape in this embodiment. When fixing, it can be adhered to the wall by adhesive stickers or letter buckles to achieve fixation. A circular extrusion cylinder 7 is provided inside the shell 1, and a piston push rod 9 is provided inside the extrusion cylinder 7. The piston push rod 9 is transmission-connected with a driving device 10 arranged in the shell 1, and the driving device 10 drives the piston push rod 9 to slide along the extrusion cylinder 7, and the piston push rod 9 extends to squeeze out the toothpaste in the extrusion cylinder 7. In order to facilitate the cleaning of the extrusion cylinder 7, a lower cover body 5 is detachably provided below the above-mentioned shell 1. When the extrusion cylinder 7 needs to be cleaned, the lower cover body 5 is disassembled from the extrusion cylinder 7. The lower cover body 5 is provided with a through hole 4, and the extrusion cylinder 7 is stuck at the through hole 4 of the lower cover body 5. At the same time, in order to facilitate the cleaning of the extrusion cylinder 7, a discharging connector 8 is detachably provided below the extrusion cylinder 7. When the extrusion cylinder 7 needs to be cleaned, the discharging connector 8 is disassembled. In this way, the extrusion cylinder 7 forms a cylinder with open ends, which can be completely cleaned by a brush, making it easy to clean. The discharge connector 8 has a discharge port 11, which extends into the through hole 4. When the piston push rod 9 extends to squeeze out the toothpaste, the toothpaste can be prevented from sticking to the through hole 4. An extension plate 2 is provided downwardly under the outer shell 1, and an induction switch 3 is provided on the side of the extension plate 2. The induction switch 3 and the driving device 10 are connected to the controller in the outer shell 1.

[0023] When it is necessary to squeeze out the toothpaste, place the toothbrush under the discharge port 11. At this time, the induction switch 3 generates an induction signal and transmits the signal to the controller. The controller controls the driving device 10 to drive the piston rod to move downward to squeeze out the toothpaste inside the extrusion tube 7. After squeezing out a certain amount, the motor 1001 reverses to suck the residual toothpaste at the outlet into the extrusion tube 7 again to prevent the toothpaste at the outlet from hardening. Then the motor 1001 stops rotating.

[0024] Furthermore, the detachable connection between the extrusion tube 7 and the discharge connector 8 is specifically achieved in the following manner: an external thread section 12 is provided near the lower end of the outer circumferential wall of the extrusion tube 7, and an internal thread section (not shown due to viewing angle issues) is provided on the inner wall of the discharge connector 8. The discharge connector 8 is threadedly connected to the extrusion tube 7, and the end of the discharge connector 8 has a discharge port 11 extending downward, and the lower edge of the discharge port 11 is flush with the lower edge of the through hole 4. The threaded connection here not only serves the purpose of detachable connection, but also the connection strength can bear a certain pressure, and the connection strength can meet the needs, because when the extrusion tube squeezes out the toothpaste, it will generate a pressure on the discharge connector 8, and the threaded connection can meet the pressure-bearing needs and ensure the connection strength.

[0025] Furthermore, the structure of the driving device 10 specifically includes a motor 1001, the motor 1001 is connected to a screw 1002, the screw 1002 is threadedly connected to a slider 1003, the slider 1003 is connected to the top of the piston push rod 9 and is also slidably connected to a guide rail 1004, the guide rail 1004 is vertically arranged on the inner side wall of the housing 1, and the guide rail 1004 extends to the lower surface of the housing 1. This structure can achieve the purpose of driving, and can facilitate the piston push rod 9 Take it out from the shell to facilitate cleaning of the piston push rod 9. Specifically, when taking out the piston push rod 9, first pull the extrusion cylinder from the piston push rod 9, take the extrusion cylinder out of the shell, and then turn on the motor 1001. The motor 1001 rotates to drive the screw 1002 to rotate, and the slider 1003 moves down along the screw 1002 until it is disengaged from the screw 1002. Then, manually pull down the piston push rod 9, slide the piston rod out of the guide rail 1004, and then the piston push rod 9 can be taken out of the shell and cleaned.

[0026] Furthermore, in order to facilitate observation of the amount of toothpaste inside and to observe whether the extrusion tube is time to be cleaned, the housing 1 and the extrusion tube 7 are both made of transparent plastic material.

[0027] Furthermore, regarding the detachable connection between the lower cover body 5 and the outer shell 1, specifically, the lower cover body 5 and the outer shell 1 are connected by screws 6. The screw 6 connection can not only meet the connection needs, but more importantly, the screw 6 connection can satisfy the role of the lower cover body 5 as a load-bearing cover body, because the extrusion cylinder is fixed on the lower cover body 5, which mainly bears the weight of the extrusion cylinder 7 and the internal toothpaste. Therefore, the screw 6 connection is reliable and the connection strength can be guaranteed.

[0028] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0029] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
