[0050] Compared with the prior art, the present invention has the following beneficial effects:

[0051] 1. The toothpaste box of the present invention is set inside the toothbrush body, integrating the toothpaste box and the toothbrush together for easy carrying. The toothpaste in the toothpaste box can be squeezed out from the toothbrush head by pushing the component, which is convenient to operate. The toothpaste box is detachably set inside the toothbrush body for easy replacement. Through the engagement of the threaded structure on the lead screw and the threaded meshing structure on the push cylinder, the rotation of the lead screw drives the push cylinder to move, thereby pushing the push piston of the toothpaste tube or the toothpaste tube made of flexible material, realizing convenient and quantitative toothpaste extrusion.

[0052] 2. The present invention limits the push cylinder by using a limiting cap on the sleeve to prevent the push cylinder from detaching from the sleeve and falling off, while also limiting the distance the push cylinder can be lifted.

[0053] 3. This invention features a protruding structure on the sleeve and a grooved structure on the rotating base. When the rotating base drives the lead screw to rotate, the rotating base and the sleeve rotate relative to each other. When the protruding structure rotates to the grooved structure, it springs into the grooved structure through the second elastic connector and collides with the inner wall of the grooved structure. As the rotating base continues to rotate, the protruding structure continuously springs into or slides out of the grooved structure, producing a clicking sound. The number of clicking sounds indicates the rotation angle of the rotating base, which also represents the rotation angle of the lead screw. For every certain angle the lead screw rotates, the distance the pusher cylinder pushes out is constant, thereby achieving quantitative pushing of the toothpaste tube piston or the flexible toothpaste tube, and realizing quantitative extrusion of toothpaste.

[0054] 4. The rotating base of the present invention is provided with a water outlet channel. During brushing, water flowing into the toothbrush body can be discharged through the water outlet channel, thereby preventing water from remaining in the toothbrush body.

[0055] 5. The toothbrush body of the present invention is provided with an observation window. Through the observation window, the remaining amount of toothpaste in the toothpaste tube can be observed at any time, so as to know how long the remaining amount of toothpaste can be used, which is convenient for preparing to replace the toothpaste tube.

[0056] 6. The components of this invention are installed with anti-misalignment protrusions and anti-misalignment grooves to avoid misalignment during installation and use. They are connected by snap-fit ​​and slots to facilitate the installation and disassembly of the components.

[0057] 7. The toothbrush of the present invention also includes a toothbrush case, which includes a detachable upper cover and a lower cover, making it easy to protect and carry the toothbrush body. At the same time, the upper cover and the lower cover can be used as a water cup.

[0058] 8. The push cylinder of the present invention is provided with a guide structure, a threaded engagement structure, and a first elastic connector. Before the sleeve and the push cylinder are installed into the toothbrush body, the threaded engagement structure does not contact the lead screw, and the lead screw and the push cylinder can move relative to each other, thereby adjusting the push cylinder to the starting position of the lead screw. After the sleeve and the push cylinder are installed into the toothbrush body, the guide structure abuts against the guide groove on the inner sidewall of the toothbrush body, the first elastic connector is compressed, the threaded engagement structure engages with the lead screw, and the rotation of the lead screw can drive the push cylinder to move. When replacing the toothpaste tube, when the sleeve and the push cylinder are removed from the toothbrush body, the guide structure has no abutting force, and the guide structure and the threaded engagement structure are reset by the elastic restoring force of the first elastic connector. The threaded engagement structure does not contact the lead screw, and the push cylinder can be adjusted to the starting position of the lead screw again, thereby solving the reset problem of the push cylinder.

[0059] 9. The push cylinder of the present invention is provided with a limiting ring and an inlet groove, and the lead screw is provided with a limiting protrusion. The limiting protrusion and the inlet groove are aligned. When the lead screw is inserted into the push cylinder, the lead screw is rotated so that the limiting protrusion is located on the limiting ring, thereby limiting the lead screw and preventing the lead screw from falling out of the push cylinder.

This facilitates the protection and carrying of the toothbrush body, and the upper and lower covers can also function as water cups.

[0109] The pushing assembly 1 includes a lead screw 101, a pushing cylinder 102, and a rotating base 103. The rotating base 103 is located at one end of the lead screw 101. The lead screw 101 is located inside the pushing cylinder 102. The pushing cylinder 102 is located inside the toothbrush body 3. The lead screw 101 can drive the pushing cylinder 102 to move within the toothbrush body 3. The pushing cylinder 102 is used to push the toothpaste tube 4.

[0110] The rotating base 103 is provided with a water outlet channel 1031, which is connected to the toothbrush body 3.

[0111] One end of the lead screw 101 is provided with an error-proof slot 1014, and the rotating base 103 is provided with an error-proof block 1032.

[0112] One end of the push cylinder 102 is provided with a limiting ring 1025 and an inlet groove 1024, and one end of the lead screw 101 is provided with a limiting protrusion 1016. The limiting protrusion 1016 and the inlet groove 1024 are adapted to each other. The limiting ring 1025 and the limiting protrusion 1016 are used to limit the lead screw 101. The limiting protrusion and the inlet groove are aligned. When the lead screw is inserted into the push cylinder and rotated, the limiting protrusion is positioned on the limiting ring, thereby limiting the lead screw and preventing it from falling out of the push cylinder.

[0113] The push cylinder 102 is provided with a guide structure 1021 and a threaded engagement structure 1022. The inner wall of the toothbrush body 3 is provided with a guide groove 301. The guide structure 1021 abuts against the guide groove 301. When the lead screw 101 rotates, the push cylinder 102 can be driven to move within the toothbrush body 3 through the threaded engagement structure 1022. When the push assembly 1 is assembled with the toothbrush body 3, the threaded engagement structure 1022 is subjected to radial inward pressure and engages with the threaded structure on the lead screw 101. The rotation of the lead screw 101 drives the push cylinder 103 to move closer to or further away from the brush head assembly 2. When the push assembly 1 is disengaged from the toothbrush body 3, the threaded engagement structure 1022 is in its natural state and separates from the threaded structure of the lead screw 101. At this time, the push cylinder 102 can freely translate towards the rotating base 103. When the pushing component 1 is disengaged from the toothbrush body 3, the distance between the outermost part of the guide structure 1021 and the central axis of the pushing cylinder 102 is greater than the distance between the guide groove 301 corresponding to the guide structure 1021 and the central axis of the toothbrush body 3; the pushing cylinder 102 and the toothbrush body 3 are coaxially arranged.

[0114] The functions of the guide structure 1021 and the guide groove 301 are: on the one hand, to provide guidance for the movement of the push cylinder 102; on the other hand, to limit the circumferential rotation of the push cylinder 102.

[0115] The pushing assembly 1 also includes a sleeve 104, with a pushing cylinder 102 disposed inside the sleeve 104. The sleeve 104 is disposed inside the toothbrush body 3.

[0123] The toothpaste tube 4 is equipped with a toothbrush tube cap 8. Before use, the toothpaste tube 4 is sealed by the toothbrush tube cap 8. When in use, the toothbrush tube cap 8 is removed from the toothpaste tube 4.

[0124] Installation process:

[0125] Install the brush head assembly 2 onto the toothbrush body 3;

[0126] Insert the toothpaste tube 4 into the toothbrush body 3 so that the toothpaste tube 44's filling head 401 is connected to the toothpaste outlet on the brush head assembly 2.

[0127] Align the limiting protrusion 1016 on the lead screw 101 with the guide groove 1024 on the push cylinder 102, and insert the lead screw 101 into the push cylinder 102 from the open end of the push cylinder 102, so that the thread engagement structure 1022 is located at the starting end of the lead screw 101. At this time, the thread engagement structure 1022 and the thread structure of the lead screw 101 are not in contact.

[0128] Align the guide structure 1021, threaded engagement structure 1022, and first elastic connector 1023 on the push cylinder 102 with the limiting through hole 1041 on the sleeve 104, and insert the push cylinder 102 with the lead screw 101 into the sleeve 104 from one open end of the sleeve 104, so that one end of the lead screw 101 used to connect to the rotating base 103 protrudes from the other open end of the sleeve 104, that is, one end of the protruding structure 1044 is provided, so that the anti-misalignment groove 1014 and the third buckle 1015 are exposed.

[0129] Align the second anti-mistake protrusion 1049 on the limit buckle cover 1042 with the second anti-mistake groove 10410 on the sleeve 104, and install the limit buckle cover 1042 on one open end of the sleeve 104 through the second buckle 1043 and the second slot 1048; at this time, 10411 is aligned with the first anti-mistake protrusion 1046.

[0130] Align the anti-error slot 1014 of the lead screw 101 with the anti-error block 1032 of the rotating base 103, and install the rotating base 103 on one end of the lead screw 101 through the third buckle 1015 and the third slot 1033, so that the sleeve 104 abuts against the abutment structure 1034 of the rotating base 103, and the end of the sleeve 104 is installed in the rotating base 103, and the sleeve 104 and the rotating base 103 can rotate relative to each other;

[0131] Align the first anti-mistake protrusion 1046 on the sleeve 104 with the first anti-mistake groove 303 on the toothbrush body 3, and at the same time align the guide structure 1021 with the guide groove 301. Push the sleeve 104 into the toothbrush body 3, so that the first buckle 1047 and the first slot 304 engage. During the pushing process, the guide structure 1021 receives the squeezing force of the toothbrush body 3. The guide structure 1021 tightens towards the lead screw 101 through the first elastic connector 1023, thereby driving the thread engagement structure 1022 to approach the lead screw 101 and engaging the thread engagement structure 1022 with the thread structure on the lead screw 101.

[0132] As the sleeve 104 is pushed in, one end of the sleeve 104 abuts against the tube body 402 of the toothpaste tube 4, and the rotating base 3 abuts against the toothpaste body 3.

[0133] After the toothpaste in the toothpaste tube 4 is used up, remove the sleeve 104 from the toothpaste body 3, take the toothpaste tube 4 out of the toothpaste body 3, and put the new toothpaste tube 4 into the toothpaste body 3.

[0134] After the sleeve 104 is removed from the toothpaste body 3, the threaded engagement structure 1022 is reset through the first elastic connector 1023. The threaded engagement structure 1022 is not in contact with the lead screw 101. The push cylinder 102 is pushed to the starting position. After reset, the sleeve 104 is reinstalled into the toothpaste body 3.

[0135] Working principle:

[0136] When brushing teeth, the rotating base 3 is rotated, which drives the lead screw 101 to rotate. The guide structure 1021 and the guide groove 301 guide the movement of the push cylinder 102. The sleeve 104 limits the circumferential rotation of the push cylinder 102. The lead screw 101 and the push cylinder 102 rotate relative to each other. The threaded structure on the lead screw 101 and the threaded engagement structure 1022 on the push cylinder 102 interact with each other, causing the push cylinder 102 to move relative to the lead screw 101. One end of the push cylinder 102 is pushed out through the limiting cover 1042.

[0137] When the toothpaste tube 4 is equipped with a push piston 5, the push cylinder 102 pushes the push piston 5 inside the toothpaste tube 4, thereby squeezing out the toothpaste inside the toothpaste tube 4, and squeezing the toothpaste out at the brush head assembly 2 through the toothpaste dispensing head 401.

[0138] When the toothpaste tube 4 is set as a flexible tube, the push cylinder 102 squeezes the toothpaste tube 4, thereby squeezing out the toothpaste inside the toothpaste tube 4, and squeezing the toothpaste out at the brush head assembly 2 through the toothpaste dispensing head 401.

[0139] Example 2:

[0140] The difference from Embodiment 1 is that a turntable structure 1011 is provided at one end of the lead screw 101, and a plurality of protrusions 1044 are provided at one end of the sleeve 104 near the turntable structure 1011. A plurality of second groove structures 1012 are provided on the turntable structure 1011. When the lead screw 101 is rotated, the turntable structure 1011 and the sleeve 104 rotate relative to each other, and the protrusions 1044 can spring into or slide out of the plurality of second groove structures 1012.

[0141] A second elastic connector 1045 is provided on the sleeve 104. Several protruding structures 1044 are connected to the sleeve 104 through the second elastic connector 1045. When the protruding structure 1044 rotates to the position of the second groove structure 1012, the protruding structure 1044 springs into the second groove structure 1012 through the second elastic connector 1045. A guide slope 1013 is provided in the second groove structure 1012, and the protruding structure 1044 slides out of the groove structure 1012 through the guide slope 1013.

[0142] The installation process becomes:

[0143] Align the guide structure 1021, threaded engagement structure 1022, and first elastic connector 1023 on the push cylinder 102 with the limiting through hole 1041 on the sleeve 104, and insert the push cylinder 102 into the sleeve 104 from one open end of the sleeve 104.

[0144] Align the second anti-mistake protrusion 1049 on the limit cover 1042 with the second anti-mistake groove 10410 on the sleeve 104, and install the limit cover 1042 on one open end of the sleeve 104 through the second buckle 1043 and the second slot 1048; at this time, the third anti-mistake protrusion 10411 is aligned with the first anti-mistake protrusion 1046.

[0145] Align the limiting protrusion 1016 on the lead screw 101 with the guide groove 1024 on the push cylinder 102, and insert the lead screw 101 into the push cylinder 102 from the open end of the push cylinder 102, so that the thread engagement structure 1022 is located at the starting end of the lead screw 101. At this time, the thread engagement structure 1022 and the thread structure of the lead screw 101 are not in contact; the turntable structure 1011 abuts against one end of the sleeve 104 where the protrusion structure 1044 is provided.

[0146] Align the error-proof slot 1014 of the lead screw 101 with the error-proof block 1032 of the rotating base 103, and install the rotating base 103 at one end of the lead screw 101 through the third buckle 1015 and the third slot 1033.

[0147] The end of the sleeve 104 is installed in the rotating base 103, and the sleeve 104 and the rotating base 103 can rotate relative to each other.

[0148] When the rotating base 103 drives the lead screw 101 to rotate, which in turn drives the turntable structure 1011 to rotate, the turntable structure 1011 and the sleeve 104 rotate relative to each other. When the protruding structure 1044 rotates to the second groove structure 1012, the protruding structure 1044 is ejected into the second groove structure 1012 through the second elastic connector 1045, colliding with the inner wall of the second groove structure 1012 and making a clicking sound. As the turntable continues to rotate, the protruding structure 1044 moves within the second groove structure 1012. The toothpaste tube 1012 slides out of the inclined plane 1013 and then bounces back into the adjacent second groove structure 1012 after moving a certain distance. The number of rotations of the turntable structure 1011 can be determined by the spacing between the adjacent second groove structures 1012 and the number of clicks. One rotation of the turntable structure 1011 means that the lead screw 101 also rotates once. The distance pushed out by the push cylinder 102 is constant for each rotation of the lead screw 101, thereby realizing the quantitative pushing of the toothpaste tube 4 and the quantitative extrusion of toothpaste.

[0149] This invention combines a toothpaste box and a toothbrush, enabling simultaneous toothpaste dispensing and brushing without the need to carry separate toothpaste, making it convenient and practical. It also allows for precise dispensing of toothpaste.
