Description

Technical Field

[0001] This invention belongs to the field of toiletries technology, specifically a convenient multi-functional toothbrush. Background Technology

[0002] As people's pace of life accelerates and their emphasis on personal hygiene increases, the demand for toothbrushes is no longer limited to basic cleaning functions. Portable multi-functional toothbrushes are designed to meet users' needs in different scenarios while providing a more efficient oral care experience.

[0003] In the prior art, CN209595052U discloses a portable toothbrush, which includes a toothbrush body, a shell that also serves as a handle, and a toothpaste shell and dental floss located inside the shell. The toothbrush body is connected to the handle shell. The handle shell has a toothpaste slot for holding the toothpaste shell and a dental floss slot for holding dental floss. A handle cover is provided on one side of the handle shell, and the handle cover has a through hole for holding dental floss. This portable toothbrush is more practical and convenient.

[0004] In the aforementioned patent, the toothbrush body is connected to the handle housing, and the handle housing is provided with a toothpaste slot for holding the toothpaste cartridge and a dental floss slot for holding dental floss, achieving the effect of being convenient to carry and use. However, this portable toothbrush still has some problems. 1. This portable toothbrush uses the traditional method of squeezing toothpaste packets to dispense toothpaste, which makes it difficult to control the amount of toothpaste dispensed, and toothpaste is prone to remain and cannot be completely dispensed, resulting in waste. 2. Bacteria will grow on the bristles of a toothbrush after prolonged use, and it needs to be replaced regularly. However, since the toothbrush has a fixed structure, it would be a huge waste to replace the entire brush. 3. Toothpaste has limited antibacterial effect and cannot effectively prevent tooth decay and ulcer formation.

The external threaded rod 601 moves up and down in the first sliding groove 108, and the limiting groove 602 is slidably connected to the second limiting block 109. The upper end of the external threaded rod 601 is fixedly connected to the middle of the bottom surface of the third fixed block 603. The top surface of the third fixed block 603 is fixedly connected to the bottom surface of the rubber stopper 604. The third fixed block 603 and the rubber stopper 604 move up and down in the toothpaste storage compartment of the liquid storage tube 101. The second sliding groove 605 is opened on the third fixed block 603 and the rubber stopper 604. The first limiting block 106 is fixed in a ring shape on the upper side of the outer wall of the liquid storage tube 101. The threaded block 3 slides and rotates up and down on the upper outer wall of the liquid storage tube 101. The threaded block 3 is threadedly connected to the lower end of the connecting rod 201. Specifically, by rotating the rotating block 401, the internal threaded rod 402 is driven to rotate on the external threaded rod 601, pushing the external threaded rod 601 to move upward in the first sliding groove 108. The external threaded rod 601 drives the third fixing block 603 and the rubber stopper 604 to move upward in the toothpaste storage compartment, squeezing the toothpaste into the toothpaste tube 202 through the second groove 105, and then out through the toothpaste tube 202 and the second tube 503 to the bristles 506, conveniently squeezing out a certain amount of toothpaste and avoiding toothpaste residue. The outlet flap 8 set in the second tube 503 prevents external liquid from flowing into the second tube 503.

[0027] Example 2 like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the lower end of the connecting pipe 103 is fixedly connected to the partition 102, and the connecting pipe 103 is connected to the sterilization liquid storage chamber of the liquid storage pipe 101. The upper end of the connecting pipe 103 is fixedly connected to the top inner side of the liquid storage pipe 101, and the connecting pipe 103 is connected to the first groove 104. The connecting pipe 103 is slidably connected to the second sliding groove 605. The pressing nozzle body 204 is set on the right side wall of the connecting rod 201, and the pressing nozzle body 204 is connected to the sterilization liquid conduit 203. The first conduit 205 is connected to the pressing nozzle body 204. The sterilization liquid conduit 203 is fitted into the first groove 104, and the first conduit 205 slides up and down in the connecting pipe 103. The lower end of the first conduit 205 extends into the sterilization liquid storage chamber of the liquid storage pipe 101. The third conduit 504 is opened on the second fixing block 501, and the rear side of the third conduit 504 is fitted and connected to the upper end of the bactericidal liquid conduit 203. An atomizing nozzle 7 is provided inside the third conduit 504, and the edge of the atomizing nozzle 7 is fixedly connected to the wall of the third conduit 504. Specifically, pressing the nozzle body 204 directs the disinfectant in the disinfectant storage chamber through the first conduit 205, the disinfectant conduit 203, and the third conduit 504, and then through the atomizing nozzle 7 to spray the teeth with atomized solution for convenient further disinfection.

[0028] Example 3 The second slot 502 is located near the bottom of the rear side wall of the second fixing block 501. The second slot 505 is fixed near the top of the rear side wall of the second fixing block 501. The first slot 208 is fixed near the bottom of the front side wall of the first fixing block 206. The first slot 207 is located near the top of the front side wall of the first fixing block 206. The first slot 208 is engaged with the second slot 502, and the first slot 207 is engaged with the second slot 505. Specifically, by engaging or disengaging the first card block 208 with the second card slot 502 and the first card slot 207 with the second card block 505, the second fixing block 501 can be fixedly connected to or separated from the first fixing block 206, thus achieving the effect of conveniently replacing the brush head 5.

[0029] Example 4 The bristles 506 are evenly fixed to the front side wall of the second fixing block 501, and the bristles 506 are arranged in an arc shape. Specifically, by setting the right end of the first fixing block 206 and the second fixing block 501 in an arc-shaped concave shape, the bristles 506 are evenly fixed to the front side wall of the second fixing block 501, which can perform a covering brushing of the teeth, and brush the top and sides of the teeth at the same time, making brushing more convenient, while avoiding damage to the gums caused by traditional brushing of the sides of the teeth.

[0030] Working principle: When using this portable multi-functional toothbrush, first move the second fixing block 501 to engage or disengage the first locking block 208 with the second locking slot 502 and the first locking slot 207 with the second locking block 505. This allows the second fixing block 501 to be fixedly connected to or separated from the first fixing block 206, enabling the replacement of the brush head 5. Next, rotating the rotating block 401 causes the internal threaded rod 402 to rotate on the external threaded rod 601, pushing the external threaded rod 601 upward within the first sliding groove 108. The external threaded rod 601 then drives the first... The three fixed blocks 603 and the rubber stopper 604 move upward in the toothpaste storage compartment, squeezing the toothpaste through the second groove 105 into the toothpaste tube 202, and then through the toothpaste tube 202 and the second tube 503 to the bristles 506, making it convenient to squeeze out a certain amount of toothpaste for brushing. Next, press the nozzle body 204 to guide the disinfectant in the disinfectant storage compartment through the first tube 205 and the disinfectant tube 203 into the third tube 504, and then through the atomizing nozzle 7 to spray the teeth with atomized spray, making it convenient to further disinfect the teeth.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
