[0034] 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.
[0035] An embodiment of the present utility model discloses a bubble electric toothbrush, as Figures 1-12 shown, including: a toothbrush main body 1 and a toothbrush head 2; a drive motor 11 and an air pump 12 are provided inside the toothbrush main body 1. A drive shaft 111 that is clamped with the toothbrush head 2 is provided on the drive motor 11. The drive shaft 111 has a structure with openings at both ends and a hollow interior. The drive shaft 111 is communicated with the outlet pipeline of the air pump 12, and the inlet of the air pump 12 is communicated with the external space; an exhaust passage 211 communicated with the drive shaft 111 is provided inside the toothbrush head 2, and an exhaust hole 212 communicated with the exhaust passage 211 is provided at one end of the toothbrush head 2.
[0036] It should be noted that by providing an exhaust passage 211 communicated with the drive shaft 111 inside the toothbrush head 2 and an exhaust hole 212 communicated with the exhaust passage 211 at one end of the toothbrush head 2, a bubble electric toothbrush is provided, which can generate bubbles while performing electric tooth cleaning, enhancing the cleaning effect of the electric toothbrush on teeth.
[0037] AsFigure 7 and Figure 10 As shown in Figure 10 , the number of exhaust holes 212 is set to two, and the two exhaust holes 212 are arranged adjacent to each other. It should be noted that by setting the two exhaust holes 212, the number of generated bubbles can be increased, and the cleaning effect of the electric toothbrush can be further enhanced.
[0038] As Figure 7 and Figure 8 As shown in Figure 8 , a sealing ring 24 that abuts against the inner wall of the toothbrush head 2 is sleeved on one end of the drive shaft 111. In the specific implementation process, the sealing ring 24 is tightly pressed against the inner wall of the toothbrush handle 21. Through the setting of the sealing ring 24, the space between the toothbrush handle 21 and the drive shaft 111 is sealed, ensuring that the air flow passes through the exhaust passage 211 and the exhaust holes 212 in sequence for discharge.
[0039] As Figures 1-6 As shown in Figures 1-6 , the toothbrush main body 1 includes a toothbrush housing 13. Inside the toothbrush housing 13, a first mounting bracket 141 and a second mounting bracket 142 are fixedly connected. The first mounting bracket 141 is slidably clamped with 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. 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, the first mounting bracket 141 and the second mounting bracket 142 are fixedly connected by screws; 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. Through the setting of the first buffer sleeve 71 and the second buffer sleeve 72, the operation of the drive motor 11 is vibration-damped; through the setting of the third buffer sleeve 73 and the fourth buffer sleeve 74, the operation of the air pump 12 is vibration-damped, thereby reducing the working noise of the bubble electric toothbrush and enhancing the user experience.
[0040] As Figures 1-12 As shown in Figures 1-12 , 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. In the specific implementation process, a charging base 6 for charging the battery 162 is installed on the first bottom cover 151.
[0041] As Figures 1-6 As shown in Figures 1-6 , 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 bubble electric toothbrush, and the second button 172 is used to control the working mode of the bubble electric toothbrush.
[0042] As Figures 1-6As shown, a connection base 18 is installed on the first bottom cover 151, and the connection base 18 is communicated with the air pump 12 through an air inlet pipe 19. In the specific implementation process, the connection base 18 and the air inlet pipe 19 are in interference fit. A first joint 81 is installed at the outlet of the air pump 12. One end of the drive shaft 111 is inserted into the first joint 81. A second joint 82 is sleeved outside the first joint 81. Vibration isolation pads 9 for vibration reduction are installed at the ends of the drive motor 11 and the air pump 12. The first joint 81 is made of soft rubber material, the second joint 82 is made of hard rubber material, and the vibration isolation pad 9 is made of elastic material.
[0043] As Figure 3 and Figure 4 shown, a top waterproof ring 3 is installed in the toothbrush housing 13. The drive shaft 111 passes through the top waterproof ring 3. The same ends of the first mounting bracket 141 and the second mounting bracket 142 are embedded in the top waterproof ring 3. In the specific implementation process, a bottom waterproof ring 4 is sleeved on the first bottom cover 151, and the bottom waterproof ring 4 is arranged in an O shape. Through the settings of the top waterproof ring 3 and the bottom waterproof ring 4, the electric toothbrush can be effectively waterproofed.
[0044] As Figures 1-6 shown, the toothbrush head 2 includes a toothbrush handle 21. A connecting piece 22 that is clamped with the drive shaft 111 is installed in the toothbrush handle 21. A plurality of bristles 23 are installed at one end of the toothbrush handle 21. An exhaust channel 211 is arranged in the toothbrush handle 21. Exhaust holes 212 are arranged adjacent to the bristles 23. In the specific implementation process, the exhaust holes 212 include a first hole section 2121, a second hole section 2122, and a third hole section 2123 arranged from outside to inside. The aperture diameters of the first hole section 2121, the second hole section 2122, and the third hole section 2123 show a decreasing trend. The connecting piece 22 is provided with a clamping arm 221, and the drive shaft 111 is provided with a clamping groove 1111 that is clamped and matched with the clamping arm 221. The clamping groove 1111 is arranged in a ring shape.
[0045] As Figure 7 and Figure 10 shown, at least one partition 213 is arranged in the toothbrush handle 21, and the partition 213 is located in the exhaust channel 211. In the specific implementation process, the partition 213 and the toothbrush handle 21 are of an integrally formed structure. Through the setting of the partition 213, the number of generated bubbles can be increased, thereby enhancing the cleaning effect of electric tooth cleaning.
[0046] Working principle: Since the toothbrush head 2 is provided with an exhaust channel 211 communicated with the drive shaft 111, and one end of the toothbrush head 2 is provided with exhaust holes 212 communicated with the exhaust channel 211, a bubble electric toothbrush is provided, which can generate bubbles while performing electric tooth cleaning, enhancing the cleaning effect of the electric toothbrush on teeth.
[0047] Obviously, the above embodiments are merely examples given 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 still fall within the protection scope of this utility model.
