Description

Technical Field

[0001] This utility model relates to the technical field of brushes, buffers, cups or similar components, specifically to an electric toothbrush with anti-drop function. Background Technology

[0002] An electric toothbrush is a type of toothbrush that is powered by electricity and cleans teeth through high-frequency vibration or rotation. Compared to traditional manual toothbrushes, electric toothbrushes can remove plaque more efficiently and reduce the risk of gingivitis and bleeding gums. To prevent damage to internal components from drops, electric toothbrushes are usually equipped with drop protection devices, such as a rubber sleeve on the handle. Since electric toothbrushes are used for only two or three minutes each time, the rubber sleeve will not significantly affect the heat dissipation function of the electric toothbrush.

[0003] However, rubber sleeves are prone to bacterial growth during use, which can affect the lifespan of the electric toothbrush and the user's oral health. Prolonged exposure to dark and damp environments can also accelerate the aging of the rubber sleeve. To extend the lifespan of the electric toothbrush and protect the user's health, the rubber sleeve needs to be removed and cleaned regularly, and it's important to replace it. However, current rubber sleeves are directly fitted onto the handle of the electric toothbrush, creating significant friction between the sleeve and the handle. This makes removing and installing the sleeve difficult, resulting in a longer cleaning time and reduced cleaning efficiency. Utility Model Content

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model provides an electric toothbrush with anti-drop function, which has the following beneficial effects:

[0023] (1) When the rubber sleeve of the electric toothbrush with anti-drop function needs to be cleaned, the disassembly block is pulled, and after transmission, the locking state of the plug rod to the connecting block is released, so that the first rubber sleeve and the second rubber sleeve can be removed from the handle for cleaning. After cleaning, the first rubber sleeve and the second rubber sleeve can be installed on the handle in the above manner. When the electric toothbrush is dropped, the first rubber sleeve and the second rubber sleeve will cushion and protect it, preventing the electric toothbrush from being damaged due to the drop. In this way, the rubber sleeve can be easily and quickly disassembled and installed from the handle, so that the time spent on disassembling and installing the rubber sleeve is not wasted during cleaning, thereby improving the cleaning efficiency of the rubber sleeve.

[0024] (2) After the fixing block is installed, it will contact the back of the first rubber sleeve. Because the fixing block is made of rubber, the greater friction will prevent the fixing block from moving out of the mounting groove. At the same time, the first and second plugs will also contact the outer surface of the plug rod, which will further increase the friction and prevent the disassembly mechanism from being released on its own. The airbag can further increase its cushioning effect. When the electric toothbrush falls, the airbag can absorb part of the impact force and reduce the damage to the electric toothbrush.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 4 This utility model provides a new technical solution: an electric toothbrush with anti-drop function, including a handle 1, a water guide shell 2 fixedly sleeved on the outer surface of the handle 1, a toothbrush head 3 provided on the upper side of the water guide shell 2, the toothbrush head 3 connected to the upper end of the handle 1, a first rubber sleeve 4 and a second rubber sleeve 5 sleeved on the outer surface of the handle 1, the first rubber sleeve 4 and the second rubber sleeve 5 have the same connection structure and are arranged symmetrically front and back, a rotating shaft 6 is connected between the first rubber sleeve 4 and the second rubber sleeve 5, the first rubber sleeve 4 and the second rubber sleeve 5 are rotatably connected through the rotating shaft 6, a charging port 7 is provided on the lower side of the first rubber sleeve 4 and the second rubber sleeve 5, and a disassembly and assembly mechanism is provided on the first rubber sleeve 4 and the second rubber sleeve 5, the first rubber sleeve 4 and the second rubber sleeve 5 can be quickly connected and disconnected through the disassembly and assembly mechanism, the disassembly and assembly mechanism includes a connecting groove 8, a connecting block 9, a plurality of first insertion ports 10, a plurality of second insertion ports 11, a mounting groove 12, a fixing block 13, a rotating rod 14, a disassembly and assembly block 15, a plurality of insertion rods 16 and four airbags 17.

[0032] Furthermore, a connecting groove 8 is formed on the front side of the second rubber sleeve 5, and a connecting block 9 is fixedly connected to the rear side of the first rubber sleeve 4. The connecting block 9 extends into the interior of the connecting groove 8. Several first insertion ports 10 are formed inside the connecting block 9, arranged vertically, and passing through the left and right sides of the connecting block 9. Several second insertion ports 11 are formed inside the second rubber sleeve 5, extending out of the outer surface of the second rubber sleeve 5. The positions of the second insertion ports 11 and the first insertion ports 10 are opposite. A mounting groove 12 is formed on the outer surface of the second rubber sleeve 5, and the mounting groove 12 is connected to the several second insertion ports 11. A fixing block 13 is provided. Inside the mounting groove 12, the rotating rod 14 is located inside the fixing block 13. The upper and lower ends of the rotating rod 14 extend out of the upper and lower sides of the fixing block 13, respectively. The upper and lower ends of the rotating rod 14 are rotatably connected to the top and bottom walls of the mounting groove 12, respectively. The disassembly block 15 is fixedly connected to the outer surface of the fixing block 13, and the fixing block 13 can be easily disassembled and assembled through the disassembly block 15. Several insertion rods 16 are fixedly connected to the right side of the fixing block 13. The insertion rods 16 are respectively adapted to the first insertion port 10 and the second insertion port 11. Four airbags 17 are respectively opened inside the first rubber sleeve 4 and the second rubber sleeve 5. The four airbags 17 are arranged in a ring array. The connecting block 9 and the fixing block 13 are both made of rubber.

[0033] When starting work, if the rubber sleeve needs to be cleaned, it needs to be removed. The user then pulls the disassembly block 15, which moves the fixing block 13, which in turn moves several insertion rods 16. The insertion rods 16 then move out from the first insertion port 10 and the second insertion port 11, releasing the locking state of the insertion rods 16 against the connecting block 9. Then, the first rubber sleeve 4 and the second rubber sleeve 5 are pulled, and the connecting block 9 moves out from the connecting groove 8, allowing the first rubber sleeve 4 and the second rubber sleeve 5 to be removed from the handle 1 for cleaning. After cleaning, the first rubber sleeve 4 and the second rubber sleeve 5 can be installed back onto the handle 1 in the same way. When the electric toothbrush falls, the first rubber sleeve 4 and the second rubber sleeve 5 will cushion and protect it, preventing damage to the electric toothbrush from the fall.

[0034] After the fixing block 13 is installed, it will contact the rear side of the first rubber sleeve 4. Because the fixing block 13 is made of rubber, the greater friction will prevent the fixing block 13 from moving out of the mounting groove 12. At the same time, the first insertion port 10 and the second insertion port 11 will also contact the outer surface of the insertion rod 16, which will further increase the friction and prevent the disassembly mechanism from being released on its own. The airbag 17 can further increase its cushioning effect. When the electric toothbrush is dropped, the airbag 17 can absorb part of the impact force and reduce the damage to the electric toothbrush. In this way, the rubber sleeve can be easily and quickly removed and installed from the handle 1, so that no long time is wasted on the removal and installation of the rubber sleeve during cleaning, thereby improving the cleaning efficiency of the rubber sleeve.

[0035] Working principle: When starting work, if the rubber sleeve needs to be cleaned, it needs to be removed. The user then pulls the disassembly block 15, which moves the fixing block 13. The fixing block 13 then moves several insertion rods 16, causing the insertion rods 16 to move out from the first insertion port 10 and the second insertion port 11. This releases the insertion rods 16 from the connecting block 9. Then, pulling the first rubber sleeve 4 and the second rubber sleeve 5 causes the connecting block 9 to move out from the connecting groove 8, allowing the first rubber sleeve 4 and the second rubber sleeve 5 to be removed from the handle 1 for cleaning. After cleaning, the first rubber sleeve 4 and the second rubber sleeve 5 can be installed back onto the handle 1 in the same way. When the electric toothbrush falls, the first rubber sleeve 4 and the second rubber sleeve 5 will cushion and protect it, preventing damage to the electric toothbrush from the fall.

[0036] After the fixing block 13 is installed, it will contact the rear side of the first rubber sleeve 4. Because the fixing block 13 is made of rubber, the greater friction will prevent the fixing block 13 from moving out of the mounting groove 12. At the same time, the first socket 10 and the second socket 11 will also contact the outer surface of the plug 16, which will further increase the friction and prevent the locking state of the disassembly and assembly mechanism from being released on its own. The airbag 17 can further increase its cushioning effect. When the electric toothbrush is dropped, the airbag 17 can absorb part of the impact force and reduce the damage to the electric toothbrush.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
