[0002] Oral hygiene is an important part of maintaining health in daily life, and toothbrushes, as a commonly used oral hygiene tool, are widely used. However, traditional toothbrushes are usually designed as separate parts, which can be inconvenient to use.

[0003] On the one hand, the separation of toothbrush and toothpaste requires people to take out the toothbrush first and then squeeze the toothpaste onto the brush head, which is cumbersome. When carrying it out, the toothbrush and toothpaste need to be stored separately, which can easily lead to clutter and inconvenience. In addition, the exposed toothbrush head is prone to bacterial and dust contamination. On the other hand, in the later stages of toothpaste use, it is difficult to squeeze out all the toothpaste from the tube, resulting in waste. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention provides a convenient toothbrush that can effectively solve the problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] According to one aspect of the present invention, the brush head includes: a housing and a brush head. One end of the housing has a receiving cavity, and the brush head is movably connected to the housing. The brush head can be moved into or out of the receiving cavity by moving the brush head. The other end of the housing has a receiving chamber for containing toothpaste. One end of the receiving chamber has a first interface, and a piston is movably embedded inside the other end of the receiving chamber. The toothpaste in the receiving chamber is squeezed out towards the first interface by moving the piston. One end of the brush head has a second interface, and the bristles of the brush head have an extrusion port. The first interface, the second interface, and the extrusion port are connected to form an extrusion channel.

[0007] Furthermore, one end of the piston is threadedly connected to a screw, and the piston can only move linearly within the receiving chamber. The other end of the screw is fixed with a knob, and one end of the outer casing has a first opening for exposing the knob.

[0008] Furthermore, the outer peripheral surface of the knob is provided with a toothed ring, and the other end face of the housing is formed with a second opening for exposing the toothed ring.

[0009] Furthermore, the piston can only move linearly within the receiving chamber, specifically: the cross-section of the receiving chamber is elliptical, and the outer circumferential surface of the piston matches the inner circumferential surface of the receiving chamber.

[0010] Furthermore, it also includes a connector, wherein the brush head is hinged to the housing in a flip-out manner, one end of the connector being connected to a first interface and the other end being connected to a second interface.

[0011] Furthermore, one side of the brush head is rotatably connected to the outer casing, and the other side has the second interface, which is rotatably inserted into one end of the connector, which is fixed inside the outer casing.

[0012] Furthermore, the connector is a right-angle two-way connector.

Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0040] like Figures 1 to 13 As shown, this solution provides a convenient toothbrush.

[0041] Please see Figures 1 to 9 The device includes a housing 1 and a brush head 2. One end of the housing 1 has a receiving cavity 14. The brush head 2 is movably connected to the housing 1, allowing it to move in or out of the receiving cavity 14. Specifically, it also includes a connector 6. The brush head 2 is hinged to the housing 1 in a flip-out manner. One end of the connector 6 is connected to a first interface 31, and the other end is connected to a second interface 21. One side of the brush head 2 is rotatably connected to the housing 1, and the other side has a second interface 21, which is rotatably inserted into one end of the connector 6. The connector 6 is fixed inside the housing 1. The connector 6 is a right-angle two-way connector. The connector 6 enables communication between the receiving cavity 3 and the brush head 2, ensuring smooth delivery of toothpaste to the extrusion port 220. The flip-out hinge of the brush head 2 to the housing 1 maintains stable communication with the connector 6 when the brush head 2 is flipped, ensuring unobstructed toothpaste extrusion.

[0042] Please see Figures 1 to 9The outer casing 1 has a receiving chamber 3 at one end for holding toothpaste. One end of the receiving chamber 3 has a first interface 31, and a piston 4 is movably embedded inside the other end of the receiving chamber 3. Moving the piston 4 causes the toothpaste in the receiving chamber 3 to be squeezed out towards the first interface 31. One end of the brush head 2 has a second interface 21, and the bristle portion 20 of the brush head 2 has an extrusion port 220. The first interface 31, the second interface 21, and the extrusion port 220 are connected to form an extrusion channel 23. Specifically, a screw 5 is threadedly connected to one end of the piston 4. The piston 4 can only move linearly within the receiving chamber 3; that is, the piston 4 cannot rotate relative to the receiving chamber 3. A guide hole 44 is provided inside the piston 4. One end of the screw 5 is rotatably inserted through the guide hole 44, and the other end is threadedly connected to the inner circumferential surface of the piston 4. The piston 4 can only move linearly within the receiving chamber 3, specifically: the cross-section of the receiving chamber 3 is elliptical, and the outer circumferential surface of the piston 4 matches the inner circumferential surface of the receiving chamber 3.

[0043] Please see Figures 1 to 4 At least one sealing ring 8 and / or sealing strip (not shown) are also fitted between the piston 4 and the receiving chamber 3. Specifically, at least two second mounting grooves 43 for mounting the sealing ring 8 are provided annularly on the outer circumferential surface of the piston 4. The sealing ring 8 improves the sealing between the piston 4 and the receiving chamber 3, ensuring that toothpaste can only be extruded through the predetermined extrusion channel 23, improving the controllability and precision of toothpaste extrusion, and preventing toothpaste residue on the inner wall of the receiving chamber 3 or accidental leakage during toothbrush carrying. At least two first mounting grooves 42 for mounting the sealing strip are provided vertically at intervals on the outer circumferential surface of the piston 4.

[0044] Please see Figures 1 to 4 A knob 51 is fixed to the other end of the screw 5, and a first opening 15 is formed at one end of the outer casing 1 to expose the knob 51. Rotating the knob 51 drives the screw 5 to rotate, causing the piston 4 to move linearly within the receiving chamber 3, stably dispensing toothpaste. The structure is simple and easy to operate, and can accurately control the amount of toothpaste dispensed. A toothed ring 511 is provided on the outer circumference of the knob 51, and a second opening 17 is formed at the other end of the outer casing 1 to expose the toothed ring 511. The toothed ring 511 increases the friction between the knob 51 and the finger, making it easier and more convenient to rotate the knob 51, improving operating comfort and convenience.

[0045] Please see Figure 10The brush also includes an extrusion head 22, which is disposed at the extrusion port 220 and located in the middle of the bristle portion 20. A plurality of elastically deformable leaflets 221 are formed at the end of the extrusion head 22 away from the brush head 2. The extrusion port 220 is opened and closed by the opening and closing of the leaflets 221. In this embodiment, there are four leaflets 221, arranged in a ring around the extrusion head 22. The leaflets 221 control the toothpaste extrusion; when toothpaste is being squeezed, the leaflets 221 open, and toothpaste flows out; when no toothpaste is being squeezed out, the leaflets 221 close to prevent toothpaste backflow or impurities from entering the extrusion port 220, keeping the extrusion port 220 clean and hygienic, and extending the toothbrush's lifespan.

[0046] Please see Figure 10 It also includes a cylinder 24, which is fixedly mounted around the extruder head 22. A plurality of guide grooves 241 are spaced apart on the outer circumferential surface of the cylinder 24 away from the extruder head 22. The cylinder 24 protects the extruder head 22 from damage. The guide grooves 241 guide the flow of toothpaste, ensuring even distribution of toothpaste on the bristles 20 and improving brushing effectiveness.

[0047] Please see Figure 1 , Figure 11 and Figure 13 The outer casing 1 includes a cover 13 for concealing or exposing the storage cavity 14. The cover 13 is flip-open and covers the opening of the storage cavity 14. The cover 13 protects the brush head 2 inside the storage cavity 14, preventing the brush head 2 from being contaminated by the outside world and keeping it clean and hygienic. The cover 13 is flip-open, making it easy to access the brush head 2 and convenient to use.

[0048] Please see Figure 12 The outer shell 1 is also provided with an observation window 16 for observing the remaining amount of toothpaste on the side near the receiving chamber 3. The observation window 16 is made of light-transmitting material.

[0049] Please see Figures 1 to 3 The outer casing 1 includes an upper casing 11 and a lower casing 12 that interlock with each other. The upper casing 11 and the lower casing 12 are fixedly connected by several fasteners 7, which are screws. The casing cover 13 is hinged to the upper casing 11. An observation window 16 is provided on the lower casing 12.

[0050] Working principle:

[0051] In use, first open the cover 13 and flip the brush head 2 from inside the storage cavity 14 to the outside. At this time, the brush head 2 forms a certain angle with the outer shell 1, which is convenient for brushing teeth. If toothpaste is needed, simply rotate the knob 51 or turn the gear ring 511. The knob 51 drives the screw 5 to rotate. The screw 5 is threadedly connected to the piston 4. The piston 4 moves linearly in the receiving chamber 3, squeezing the toothpaste in the receiving chamber 3 toward the first interface 31.

[0052] The toothpaste passes sequentially through the first interface 31, the connector 6, and the second interface 21, finally reaching the extrusion port 220 of the brush head 2. The extrusion port 222 is located at the extrusion port 220. When toothpaste is extruded from the extrusion port 220, several leaflets 221 open under the pressure of the toothpaste, allowing the toothpaste to flow out from between the leaflets 221. The toothpaste then flows through the guide groove 241 of the cylinder 24 to the bristle section 20. After brushing, the brush head 2 is flipped over and retracted into the storage cavity 14, and the cover 13 is closed to protect the brush head 2 from contamination.

[0053] To dispense more toothpaste, simply repeat the action of rotating knob 51. The remaining amount of toothpaste in chamber 3 can be visually observed through observation window 16.
