[0039] 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.

[0040] An embodiment of the present utility model discloses a water-spraying electric toothbrush, as Figure 1-16 shown, which includes a toothbrush main body 1, a toothbrush head 2 and a water storage cup 3. A driving motor 11 and an air pump 12 are provided in the toothbrush main body 1. A driving shaft 111 engaged with the toothbrush head 2 is provided on the driving motor 11. The driving shaft 111 has a structure with openings at both ends and a hollow interior. A water outlet passage 211 communicated with the driving shaft 111 is provided in the toothbrush head 2. A water spraying hole 212 communicated with the water outlet passage 211 is provided at one end of the toothbrush head 2.

[0041] A first water inlet pipe 4 is installed at the bottom of the toothbrush main body 1. One end of the first water inlet pipe 4 is located in the water storage cup 3, and the other end of the first water inlet pipe 4 is communicated with the air pump 12. The water outlet of the air pump 12 is communicated with the driving shaft 111. In the specific implementation process, the driving shaft 111 and the air pump 12 are communicated through a first joint 81. The first joint 81 is sleeved with a second joint 82. The first joint 81 is made of soft rubber material, and the second joint 82 is made of hard rubber material. Vibration isolation pads 83 are installed at the ends of the driving motor 11 and the air pump 12.

[0042] It should be noted that the air pump 12 pumps the water in the water storage cup 3, which flows through the driving shaft 111 and the water outlet passage 211 in sequence and is sprayed out from the water spraying hole 212. The driving motor 11 provides driving power for the toothbrush head 2, thereby providing a water-spraying electric toothbrush with a water spraying function and enhancing the user experience.

[0043] As Figure 1-16 shown, a connection seat 18 is installed in the toothbrush main body 1. A second water inlet pipe 19 is installed at the water inlet of the air pump 12. The first water inlet pipe 4 and the second water inlet pipe 19 are respectively inserted and matched with the connection seat 18.

[0044] As Figure 2-4 shown, a filtering component 5 is installed at one end of the first water inlet pipe 4 located in the water storage cup 3. The filtering component 5 is used to filter the water in the water storage cup 3.

[0045] As shown Figure 2-4 in FIG. 3, the filtering component 5 includes a first filtering housing 51, a filter screen 52 is lapped inside the first filtering housing 51, and a second filtering housing 53 communicating with the first water inlet pipe 4 is clamped to the first filtering housing 51. In the specific implementation process, the second filtering housing 53 is in interference fit with the first water inlet pipe 4. Through the filtering effect of the filter screen 52, large particles are prevented from entering, ensuring the normal use of the water spraying electric toothbrush.

[0046] As shown Figure 5-10 in FIG. 4, the toothbrush main body 1 includes a toothbrush housing 13. A first mounting bracket 141 and a second mounting bracket 142 which are tightly connected are arranged inside the toothbrush housing 13. The first mounting bracket 141 is slidably clamped to the toothbrush housing 13. The drive motor 11 and the air pump 12 are both installed between the first mounting bracket 141 and the second mounting bracket 142. One end of the first mounting bracket 141 is clamped with a first bottom cover 151, and a second bottom cover 152 is sleeved on the first bottom cover 151. In the specific implementation process, a decorative ring 9 is sleeved on the second bottom cover 152, and a charging base 10 for charging the water spraying electric toothbrush is installed on the first bottom cover 151.

[0047] As shown Figure 5-10 in FIG. 5, a top waterproof ring 61 is installed inside the toothbrush housing 13. The drive shaft 111 passes through the top waterproof ring 61, and the same end of the first mounting bracket 141 and the second mounting bracket 142 is embedded inside the top waterproof ring 61. A bottom waterproof ring 62 abutting against the toothbrush housing 13 is sleeved on the first bottom cover 151. Through the arrangement of the top waterproof ring 61 and the bottom waterproof ring 62, the toothbrush main body 1 can be effectively waterproofed.

[0048] As shown Figure 5-10 in FIG. 6, a control board 161 electrically connected to the drive motor 11 is installed on the side wall of the first mounting bracket 141, and a battery 162 electrically connected to the control board 161 is clamped inside the first mounting bracket 141. A first button 171 and a second button 172 are installed on the toothbrush housing 13. The first button 171 is used to control the on / off state of the water spraying electric toothbrush, and the second button 172 is used to control the working mode of the water spraying electric toothbrush.

[0049] It should be noted that the battery 162 provides working electric energy for the toothbrush. The control board 161 is electrically connected to the air pump 12. The control board 161 separately controls the working states of the drive motor 11 and the air pump 12, realizing water spraying while performing electric tooth cleaning, and improving the user experience.

[0050] As shown Figure 7 and Figure 9As shown in the figure, a first buffer sleeve 71 and a second buffer sleeve 72 are sleeved on the drive motor 11, and a third buffer sleeve 73 and a fourth buffer sleeve 74 are sleeved on the air pump 12. It should be noted that both the first buffer sleeve 71 and the second buffer sleeve 72 are made of silica gel material, which can reduce the vibration during the operation of the drive motor 11; both the third buffer sleeve 73 and the fourth buffer sleeve 74 are made of silica gel material, which can reduce the vibration during the operation of the air pump 12. The air pump 12 can be a pneumatic diaphragm pump.

[0051] As Figure 11-14 shown, the toothbrush head 2 includes a toothbrush handle 21. A plurality of bristles 22 are installed at one end of the toothbrush handle 21. A water outlet channel 211 is arranged inside the toothbrush handle 21, and a water spraying hole 212 is arranged adjacent to the bristles 22; a connecting member 23 that is clamped with the drive shaft 111 is installed inside the toothbrush handle 21. The connecting member 23 is provided with a clamping arm 231, and the drive shaft 111 is provided with a clamping groove 1111 that is clamped and matched with the clamping arm 231. The clamping groove 1111 is arranged in a ring shape. A partition 213 located inside the water outlet channel 211 is arranged inside the toothbrush handle 21.

[0052] In the specific implementation process, a sealing ring 24 that abuts against the inner wall of the toothbrush handle 21 is sleeved on one end of the drive shaft 111. The sealing ring 24 is arranged in an O shape and is made of silica gel material; through the arrangement of the sealing ring 24, effective sealing can be carried out between the toothbrush head 2 and the drive shaft 111 to prevent water leakage.

[0053] As Figure 11 and Figure 14 shown, the water spraying hole 212 includes a first hole section 2121, a second hole section 2122, and a third hole section 2123 that are sequentially arranged in a penetrating manner from the outside to the inside. The third hole section 2123 is communicated with the water outlet channel 211, and the diameters of the first hole section 2121, the second hole section 2122, and the third hole section 2123 show a decreasing trend. It should be noted that due to the decreasing trend of the diameters of the first hole section 2121, the second hole section 2122, and the third hole section 2123, the water in the water outlet channel 211 can be quickly ejected.

[0054] Working principle: The air pump 12 pumps the water in the water storage cup 3, which sequentially flows through the drive shaft 111 and the water outlet channel 211, and is ejected from the water spraying hole 212. The drive motor 11 provides driving power for the toothbrush head 2, thereby providing a water spraying electric toothbrush, enabling it to have a water spraying function and enhancing the user experience.

[0055] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the creation of the present utility model.
