[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0032] An embodiment of the present utility model discloses a toothbrush flushing structure, as Figures 1-9 shown, which includes: a toothbrush head 1, a drive motor 2, and an air pump 3. The toothbrush head 1 has a communicating drainage channel 111 and a discharge hole 112; a drive shaft 21 for driving the toothbrush head 1 to move is provided on the drive motor 2. The drive shaft 21 has a structure with openings at both ends and a hollow interior. One end of the drive shaft 21 is clamped with the toothbrush head 1, and the other end of the drive shaft 21 is connected to the outlet of the air pump 3 through a joint 9 for pipeline connection; the air pump 3 is used to extract external water and make the water flow through the drive shaft 21, the drainage channel 111, and the discharge hole 112 in sequence to realize toothbrush flushing. In this embodiment, the air pump 3 is a pneumatic diaphragm pump.
[0033] It should be noted that by extracting external water through the air pump 3 and making the water flow through the drive shaft 21, the drainage channel 111, and the discharge hole 112 in sequence, flushing is realized, and thus a toothbrush flushing structure is provided, enabling the toothbrush to have a flushing function.
[0034] As Figures 1-9 shown, a first water inlet pipe 4 is installed at the inlet of the air pump 3.
[0035] As Figure 1 and Figure 6 shown, a communicating connection seat 5 is installed on the first water inlet pipe 4, and a communicating second water inlet pipe 6 is installed on the connection seat 5. Both the first water inlet pipe 4 and the connection seat 5 are installed in the toothbrush main body, and the second water inlet pipe 6 is embedded in the toothbrush main body. In this embodiment, by providing the externally arranged second water inlet pipe 6, it is convenient for the air pump 3 to extract external water sources.
[0036] As Figures 1-9As shown, it further includes a water storage cup 8, and a filter assembly 7 located inside the water storage cup 8 is installed on the second water inlet pipe 6. It should be noted that the cooperation between the water storage cup 8 and the toothbrush head 1 can achieve flushing while performing electric tooth cleaning; through the setting of the filter assembly 7, the water can be filtered to ensure the flushing safety of the user.
[0037] As Figures 7-9 shown, the filter assembly 7 includes a first filter housing 71, a filter net 72 is lapped inside the first filter housing 71, and a second filter housing 73 communicating with the second water inlet pipe 6 is snap-connected to the first filter housing 71. It should be noted that one end of the second filter housing 73 is embedded into the second water inlet pipe 6. Through the setting of the filter net 72, the water in the water storage cup 8 can be filtered to ensure the flushing safety of the user.
[0038] As Figures 1-4 shown, the toothbrush head 1 includes a toothbrush handle 11, a plurality of bristles 12 are installed at one end of the toothbrush handle 11, a drainage channel 111 is arranged inside the toothbrush handle 11, and a discharge hole 112 is arranged adjacent to the bristles 12; a connecting member 13 snap-connected to the drive shaft 21 is installed inside the toothbrush handle 11. In this embodiment, the connecting member 13 and the toothbrush handle 11 are fixed by ultrasonic welding or bonding. Through the driving action of the drive shaft 21, the toothbrush head 1 can be driven to vibrate or swing, realizing electric tooth cleaning.
[0039] As Figure 3 and Figure 4 shown, a waterproof ring 14 located inside the toothbrush handle 11 is sleeved on the drive shaft 21. In the specific implementation process, the waterproof ring 14 is arranged in an O shape and is made of silica gel material; one end of the drive shaft 21 abuts against the inner wall of the toothbrush handle 11. Through the setting of the waterproof ring 14, the toothbrush head 1 can be effectively waterproofed.
[0040] As Figure 3 and Figure 4 shown, the discharge hole 112 includes a first hole section 1121, a second hole section 1122, and a third hole section 1123 that are sequentially arranged in a penetrating manner from the outside to the inside. The third hole section 1123 is communicated with the drainage channel 111, and the diameters of the first hole section 1121, the second hole section 1122, and the third hole section 1123 show a decreasing trend. It should be noted that due to the decreasing trend of the diameters of the first hole section 1121, the second hole section 1122, and the third hole section 1123, the water in the drainage channel 111 can be quickly ejected.
[0041] As Figure 3 and Figure 4As shown, the connecting member 13 is provided with a clamping arm 131, and the driving shaft 21 is provided with a clamping groove 211 adapted to the clamping arm 131. In the specific implementation process, the clamping arm 131 and the connecting member 13 are of an integrally formed structure. Through the cooperation of the clamping arm 131 and the clamping groove 211, it is convenient for the driving shaft 21 to perform clamping assembly on the toothbrush head 1.
[0042] As Figures 3-5 shown, the clamping groove 211 is arranged in a ring shape. It should be noted that since the clamping groove 211 is arranged in a ring shape, the driving shaft 21 can be inserted into the toothbrush handle 11 at any angle, and the clamping arm 131 and the clamping groove 211 are quickly clamped and matched.
[0043] Working principle: The external water is extracted by the air pump 3, and the water flows through the driving shaft 21, the drainage channel 111 and the discharge hole 112 in sequence, realizing flushing, and thus providing a toothbrush flushing structure, enabling the toothbrush to have a flushing function.
[0044] Obviously, the above embodiments are only examples for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
