Description

Technical Field

[0001] This utility model relates to the field of dental cleaning equipment, specifically to a telescopic electric interdental brush with a rinsing function. Background Technology

[0002] Periodontitis is recognized by the World Health Organization as the third leading health threat after cancer and cardiovascular disease, and is also the number one enemy of oral health. Effective interdental cleaning can reduce plaque, thereby lowering the risk of periodontal disease. Interdental spaces can be cleaned using a toothbrush, water flosser, and interdental brush. For patients with larger interdental spaces, water flossers and interdental brushes are more commonly used cleaning tools.

[0003] While water flossers use high-pressure water jets for cleaning, the direction and force of the spray are difficult to control, potentially reducing cleaning efficiency and preventing them from completely replacing the function of interdental brushes. Furthermore, interdental brushes have difficulty accessing narrow or deep interdental spaces and are inconvenient for people with limited hand dexterity, such as the elderly or children. Therefore, it is necessary to provide a new, easy-to-use smart interdental brush to solve these technical problems. Additionally, existing interdental brush heads use a relatively hard material for the central axis that holds the bristles, which can easily irritate and even damage the gums during use.

[0031] See Figures 1-8 As shown, the technical solution adopted in this specific embodiment is as follows: It includes a main body 2, inside which a micro motor 9 and a micro water pump 10 are installed. The micro motor 9 is located at the upper end of the micro water pump 10, and a reciprocating mechanism 8 is installed at the power end of the micro motor 9. A brush head mounting head 7 is installed at one end of the reciprocating mechanism 8. An interdental brush head 1 is provided on the brush head mounting head 7. The water outlet of the micro water pump 10 is connected to the brush head mounting head 7. An extension water pipe 6 is installed at the water inlet end of the micro water pump 10. A water storage cup 5 is installed at the lower end of the main body 2, and the extension water pipe 6 is located in the inner cavity of the water storage cup 5. Inside the main body 2, a storage battery 11 and a control main board 12 are also provided. The storage battery 11 and the control main board 12 are electrically connected.

[0032] More specifically, the main body 2 is equipped with operation buttons 3 for controlling the equipment and indicator lights 4 for users to observe the equipment status.

[0033] More specifically, the interdental brush head 1 includes a bristle tube 1-2 and a connecting tube 1-4. One end of the bristle tube 1-2 is fixedly connected to the connecting tube 1-4. A brush head protective sleeve 1-7 is fitted onto the top end of the bristle tube 1-2. An upper flushing hole 1-1 and a lower flushing hole 1-6 are provided on the bristle tube 1-2. Several bristles 1-3 are provided on the outer wall of the bristle tube 1-2. The bristles 1-3 at the top end of the bristle tube 1-2 are short, and the bristles 1-3 at the bottom end of the bristle tube 1-2 are long. A brush head sealing ring 1-5 is installed on the lower outer side of the connecting tube 1-4. When installing the interdental brush head 1 onto the brush head mounting head 7, the user only needs to insert the connecting tube 1-4 and the brush head sealing ring 1-5 into the water storage chamber I of the brush head mounting head 7, ensuring that the water storage chamber I and the water passage chamber II form a connecting pipe. Since the brush head sealing ring 1-5 and the large sealing ring 7-3 seal each other and the small sealing ring 7-4 seal each other, the water source passes through the water passage chamber II and is flushed out from the upper flushing hole 1-1 and the lower flushing hole 1-6. The bristles 1-3 on the bristle tube 1-2 are used to clean the teeth. The brush head protective sleeve 1-7 is made of soft materials such as rubber, soft plastic, and silicone, which can effectively protect the user's gums and prevent water from flowing out from the end of the bristle tube 1-2. The bristles on the outside of the bristle tube are conical with a small head and a large tail. Because the bristles 1-3 at the top of the bristle tube 1-2 are short, and the bristles 1-3 at the bottom of the bristle tube 1-2 are long, it is convenient for users to insert the bristles 1-3 at the head into the gaps between teeth more easily, while the bristles 1-3 at the bottom can better clean the gaps between teeth and teeth. Of course, the bristles on the outside of the bristle tube can also be the commonly used bristles of the same diameter.

[0034] More specifically, the brush tube 1-2 and the connecting tube 1-4 are integral tubes, and the inner cavity of the brush tube 1-2 and the inner cavity of the connecting tube 1-4 are connected to form a water passage cavity II. The water passage cavity II allows the water source to flow more smoothly to the upper flushing hole 1-1 and the lower flushing hole 1-6. The integral manufacturing of the brush tube 1-2 and the connecting tube 1-4 facilitates production and manufacturing, and ensures their overall strength.

[0035] More specifically, a lower sealing plate 2-3 is installed at the lower end of the battery 11, and buffer pads are provided on the outer sides of both the battery 11 and the control main board 12. A motor support plate 2-1 is provided at the lower end of the micro motor 9, and an upper sealing plate 2-2 is installed at the upper end of the micro motor 9. A sealing ring is provided between the micro motor 9 and the upper sealing plate 2-2. The motor support plate 2-1 is used to support the micro motor 9, while the upper sealing plate 2-2 and the lower sealing plate 2-3 can ensure the dryness of the inside of its main body 2.

[0036] More specifically, the brush head mounting head 7 includes a main frame 7-1, one end of which is fixedly connected to the reciprocating mechanism 8, and the other end of which has a water storage chamber I. A large sealing ring 7-3 and a small sealing ring 7-4 are installed inside the water storage chamber I, and a water inlet 7-2 is located on one side of the water storage chamber I. Its drain pipe 10-1 is connected to the water inlet 7-2, allowing the micro water pump 10 to draw water into the water storage chamber I and then circulate the water through the water storage chamber I to the water passage chamber II. The large sealing ring 7-3 and the small sealing ring 7-4 are used to cooperate with the brush head sealing ring 1-5 to ensure the seal between the interdental brush head 1 and the brush head mounting head 7.

[0037] More specifically, the reciprocating mechanism 8 includes a support plate 8-1, which is installed inside the top of the main body 2. The support plate 8-1 is provided with a positioning block 8-6. A reciprocating crossbar 8-5 is slidably connected to the inner side of the positioning block 8-6. One end of the reciprocating crossbar 8-5 is fixedly connected to the brush head mounting head 7, and the other end of the reciprocating crossbar 8-5 is fixedly connected to a movable connecting plate 8-4. A second transmission rod 8-3 is movably connected to one end of the movable connecting plate 8-4. The other end of the second transmission rod 8-3 is mechanically connected to a first transmission plate 8-2, and the first transmission plate 8-2 is connected to the output shaft of the micro motor 9. When the micro motor 9 is working, the output shaft of the micro motor 9 will drive the first transmission plate 8-2 to rotate. The first transmission plate 8-2 will drive the second transmission rod 8-3 to perform circular motion, and the second transmission rod 8-3 will pull the movable connecting plate 8-4 and the reciprocating crossbar 8-5. Since the reciprocating crossbar 8-5 is slidably connected to the positioning block 8-6, the reciprocating crossbar 8-5 can only perform reciprocating motion. In turn, the reciprocating crossbar 8-5 will drive the brush head mounting head 7 to perform a certain range of reciprocating motion, thereby driving the interdental brush head 1 to perform reciprocating cleaning operation.

[0038] More specifically, the micro water pump 10 has a suction pipe 10-2 installed on its inlet end, which is connected to the extension water pipe 6. The micro water pump 10 has a drain pipe 10-1 installed on its outlet pipe, with the other end of the drain pipe 10-1 connected to the inlet 7-2. The drain pipe 10-1 and the suction pipe 10-2 ensure the normal operation of the micro water pump 10 and keep the inside of its main body 2 dry.

[0039] More specifically, the operation button 3, indicator light 4, micro motor 9 and micro water pump 10 are all electrically connected to its control motherboard 12.

[0040] More specifically, the battery 11 uses wireless magnetic charging. Magnetic charging reduces the number of openings in its main body 2, thereby further ensuring the device's waterproof sealing.

[0041] The working principle of this utility model is as follows: Before using this device, the user should fill the water storage cup 5 with water to ensure the normal operation of the micro water pump 10, and install the interdental brush head 1 on the brush head mounting head 7. When installing the interdental brush head 1, the user should ensure that the brush head sealing ring 1-5 fits the large sealing ring 7-3 and the small sealing ring 7-4. Then, the user can use the device normally. When using the device, the user only needs to turn on the device by operating button 3. After turning on, the micro motor 9 will drive the reciprocating mechanism 8 to work, and the reciprocating mechanism 8 will convert the rotational force of the micro motor 9 into reciprocating force, thereby driving the brush head mounting head 7 to perform reciprocating motion. Under the drive of the brush head mounting head 7, the interdental brush head 1... The brush head 1 will also reciprocate to help users clean their teeth. While cleaning their teeth, users can also turn on the micro water pump 10 to draw water from the water reservoir 5 into the water storage chamber I of the brush head mounting head 7. The water is then guided through the water storage chamber I to the water passage chamber II and finally flushed out through the upper flushing hole 1-1 and the lower flushing hole 1-6 to rinse the teeth and further ensure their cleanliness. The device is also equipped with an outer cover with a UV lamp (marked in the figure). When not in use, users can use the outer cover to protect the device and disinfect it with the built-in UV lamp to ensure its cleanliness.

[0042] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
