Description

Technical Field

[0001] The utility model relates to the technical field of electric toothbrushes, in particular to an electric toothbrush capable of automatically and accurately supplying toothpaste. Background Art

[0002] An electric toothbrush uses the rapid rotation or vibration of the electric motor to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth and has a massage effect on the gum tissue. In principle, there are two types of electric toothbrushes: rotational and vibrational. The vibration type of toothbrush has an electrically driven vibration motor inside that allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle, but the amplitude of the swing is very small, generally about 5 mm up and down. The industry's largest swing amplitude is 6 mm. When brushing your teeth, on the one hand, the high-frequency swinging brush head can efficiently complete the action of brushing your teeth. On the other hand, the tens of thousands of vibrations per minute also cause the mixture of toothpaste and water in the mouth to produce a large number of tiny bubbles. The pressure generated when the bubbles burst can penetrate deep into the teeth to clean dirt.

[0003] Existing electric toothbrushes still have many shortcomings. For example, people who pay attention to oral hygiene when traveling have 8 to 10 essential items when traveling, which can be described as "dragging the whole family with them." They will choose toothpaste, toothbrushes, pointed brushes, interdental brushes, mouthwash, mouth spray, dental floss, water flossers and storage bags as oral hygiene items when traveling. Most people use a container or storage bag to group the required items together, but the size and usage of the products are different, and carrying and storage are a headache. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0028] An electric toothbrush that automatically and accurately supplies toothpaste, such as Figure 1 and Figure 2 As shown, it includes a shell 1, a circuit board shell 2, and an operation button 3. The shell 1 and the circuit board shell 2 are fixedly connected, the circuit board shell 2 is connected to the operation button 3, a connector 4 is fixedly provided on the upper end of the shell 1, a toothbrush rod 5 is connected to the upper end of the connector 4, toothbrush bristles 6 are provided on one side of the toothbrush rod 5, and a disassembly shell 7 is connected to the outer wall of the shell 1.

[0029] like Figure 3 , Figure 4 and Figure 6 As shown, a vibration motor 8 and a threaded pump 10 are fixedly provided on the inner wall of the upper end of the shell 1, a vibration rod 9 is fixedly connected to the upper end of the vibration motor 8, a channel 17 is connected to the outer wall of the threaded pump 10, the channel 17 and the toothpaste tube 13 are connected by a spring tube 21, a lifting plate 14 is movably connected to the inner wall of the toothpaste tube 13, a threaded rod 15 is connected to the inner wall of the lifting plate 14, a rotating head 16 is provided at the lower end of the threaded rod 15, a discharge pipe 20 is provided at the upper end of the toothpaste tube 13, and the discharge pipe 20 and the spring tube 21 are connected by a telescopic spring 22.

[0030] Working principle of embodiment 1: after removing the disassembly shell 7 from the outer shell 1, install the toothpaste tube 13 into the inner part of the outer shell 1, and then reinstall the disassembly shell 7 on the outer shell 1. The disassembly shell 7 and the outer shell 1 are connected through the latch teeth and the latch groove. After the toothpaste tube 13 is installed, the discharge pipe 20 at the upper end of the toothpaste tube 13 will be connected with the channel 17. The discharge pipe 20 ejects the spring tube 21 through the telescopic spring 22, thereby connecting the spring tube 21 to the inner wall of the channel 17. Then, the threaded rod 15 is driven to rotate by the rotating head 16, and the threaded rod The outer wall of 15 is connected to the lifting plate 14. After the toothpaste tube 13 is installed in the housing 1, the lifting plate 14 will be connected to the reducer. The rotating head 16 will be connected to the driving motor 24 through the reducer. The driving motor 24 drives the rotating head 16 to rotate through the output shaft 24 on the reducer 25, and the lifting plate 14 moves upward on the surface of the threaded rod 15. The outer ring of the lifting plate 14 is provided with a rubber ring 23. When the lifting plate 14 squeezes the toothpaste on the inner wall of the toothpaste tube 13, it is ensured that the toothpaste will not leak from the bottom, and then the toothpaste enters the threaded pump 1 from the inside of the channel 17. 0, and is distributed through the screw pump 10. The screw pump liquid distribution technology is to apply pressure to the liquid in the distribution valve by driving the screw to rotate through the motor, forcing the liquid material to flow in the spiral direction and finally squeezed out from the nozzle. The operation of this mechanism requires the screw pump to be controlled by the circuit. The quantitative distribution can be achieved by adding a quantitative valve 28 at the output port. The quantitative valve is a device that realizes flow control by reducing the medium chamber. In the quantitative valve, the medium enters the valve body through the valve and is controlled by the valve body and the valve. When the valve is opened, the medium can flow. When the valve is opened, the medium can flow. After closing, the medium cannot pass through, thereby achieving flow control. Then the threaded pump 10 delivers the toothpaste into the delivery chamber inside the connector 4, connects the plug hole 18 set in the toothbrush rod 5 with the vibration rod 9, and then the flow chamber inside the toothbrush rod 5 is aligned with the delivery chamber in the connector 4, so that the threaded pump 10 can squeeze the toothpaste from the delivery chamber and the flow chamber onto the toothbrush bristles 6, and then controls the vibration motor 8 through the operation button 3. The vibration motor 8 makes the toothbrush rod 5 vibrate through the vibration rod 9, thereby generating sound waves to clean the teeth. Example 2

[0031] Embodiment 2 is based on embodiment 1, as Figure 7 As shown, after the toothbrush rod 5 is disassembled, it can be connected to the fixing platform 11 , and the inner wall of the fixing platform 11 is connected to the disinfection chamber 12 .

[0032] When the electric toothbrush is not in use, the toothbrush rod 5 can be removed from the vibration rod 9, and then the toothbrush rod 5 can be fixed on the fixing platform 11, and then the disinfection chamber 12 can be covered on the fixing platform 11, so as to protect the toothbrush rod 5.
