Description

Technical Field

[0001] The present invention relates to the field of tooth care, and more particularly to a combined flushing toothbrush. Background Art

[0002] An electric toothbrush is a toothbrush that is driven by electricity. It can achieve the effect of cleaning teeth by rapid rotation or vibration of the electric motor to make the brush head produce high-frequency vibration.

[0003] In order to solve the problem that the existing toothbrush can only clean with the bristles and the cleaning intensity is relatively low, the prior art (Chinese invention patent application with publication number CN113796980A) discloses a replaceable automatic water-spraying toothbrush, which provides a micro air pump and a water pump inside the toothbrush so that the toothbrush has the functions of spraying water and air, thereby realizing the use of water and gas to assist the bristles to clean the teeth, providing convenience for people.

[0004] Although the existing technology can achieve the functions of water spraying and air jetting, the gas pipeline and water pipeline in the existing toothbrush are designed separately, and the water spraying and air jetting need to be switched separately and used separately. When the water spraying or air jetting function is used alone, the best cleaning effect may not be achieved at the same time, affecting the user's experience. For example, using high-pressure water flow alone when cleaning teeth may cause certain impact and damage to the gums, and continuous air jetting alone may make the mouth feel dry and uncomfortable.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) This solution connects the pump body and the output end of the micro air pump to the metal pipe through a one-way valve. Not only can the air jet and water jet be used separately, but also the water jet and air jet can be combined for simultaneous flushing. The mixture of water and gas produces an effect similar to that of bubbling water. The bursting of bubbles in the water will bring a stronger impact force, which helps to remove stubborn dirt on the surface of teeth and in the gaps between teeth. At the same time, the mixed jet can make the water flow softer, which can reduce irritation and damage to the gums while maintaining the cleaning effect, thereby improving the comfort of use.

[0022] (2) The present solution is provided with an adjustment component, which is used to adjust the direction of the block and the output tube, thereby realizing the adjustment of the spray angle of the water spray and the air jet. By adjusting the angle, the water flow or air flow can better enter the difficult-to-clean areas such as the gaps between teeth, under the gum line, and behind the teeth, assisting the bristles to perform deep cleaning and more comprehensively clean the entire oral cavity. The adjustable angle of the water spray and air jet function makes cleaning more targeted, shortens the brushing time by reducing repetitive operations, and the user does not have to repeatedly adjust the position of the brush head. By adjusting the spray angle, a wider cleaning range can be covered.

[0023] (3) This solution is provided with a speed-up and mixing section. When the water flow or water-gas mixture passes through the speed-up and mixing section, the water flow will generate negative pressure at the throat and mix with the gas discharged by the air pump. The spiral guide flange promotes the spiral motion of the water flow, making the bubbles more evenly distributed in the water flow. The small and uniform bubbles increase the impact force and stability of the mixture, further enhancing the gas-liquid mixing effect, making the gas distribution more even, and generating fine small bubbles, which helps to increase the gas-liquid contact area. At the same time, the spiral guide flange guides the gas-liquid mixed flow into a turbulent state, enhancing the impact force of the fluid. Turbulence can better hit the target surface, such as the tooth surface, tooth gaps and other parts. The gas-liquid mixed flow generated after the bubbles are compressed and accelerated will produce a bubble bursting effect when it contacts the tooth surface, thereby forming a tiny shock wave to help clean stubborn dirt.

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 15A combined flushing toothbrush comprises a gripping portion 1 and a brush head 3 plugged into the upper end of the gripping portion 1, wherein the gripping portion 1 comprises a housing 11, a motor 14 and a battery 16 fixedly connected to the inside of the housing 11, a transmission member 13 fixedly connected to the output shaft of the motor 14, and a pipeline 3 5 fixedly connected to the inside of the transmission member 13, wherein one end of the pipeline 3 5 passes through the housing 11 and extends outward;

[0043] The brush head 3 includes an insert rod 31, a slot 33 provided inside the insert rod 31 for accommodating the transmission member 13, a pipeline 34 fixed inside the insert rod 31, bristles 32 fixed to one side of the insert rod 31, a movable groove 36 provided inside the insert rod 31, a block 37 connected to the inner wall of the movable groove 36, an output pipe 38 fixed inside the block 37, and a hose 39 connecting one end of the output pipe 38 to one end of the pipeline 34;

[0044] It also includes an installation part 2 inserted at the lower end of the gripping part 1, the installation part 2 includes a second shell 22 sleeved on the outside of the first shell 11, a second battery 28 fixed inside the second shell 22, and a gas-liquid supply unit 7 fixed inside the second shell 22;

[0045] The gas-liquid supply unit 7 includes a micro air pump 71 and a water tank 72 fixedly connected to the inside of the shell 22, a metal pipeline 74 and a pump body 73 fixedly connected to the inside of the shell 22, and the output end of the micro air pump 71 and the output end of the pump body 73 are connected to the metal pipeline 74 through a one-way valve 79, the input end of the pump body 73 is connected to the water tank 72, one end of the metal pipeline 74 is fixedly connected to the pipeline 2 4, and the other end of the pipeline 2 4 is connected to the extended end of the pipeline 3 5.

[0046] The holding portion 1 also includes a control board 15 fixedly connected to the inside of the shell 11, a pressing cover 12 movably connected to the inside of the shell 11 and connected to the control board 15, a rubber member 6 sleeved on the outside of the battery 16 and the motor 14, a charging portion 17 fixedly connected to the inside of the shell 11 and electrically connected to the battery, and a waterproof cover 18 snapped onto the lower end of the shell 11.

[0047] One end of the transmission member 13 passes through the shell 11 and is inserted into the slot 33, and a waterproof cover 131 is connected between the outside of the transmission member 13 and the shell 11. A hollow flange 132 is integrally formed at one end of the transmission member 13, and a flange groove 35 for accommodating the hollow flange 132 is opened on the inner wall of the slot 33.

[0048] The mounting part 2 also includes a control board 26 fixedly connected to the inside of the shell 22, a pressing cover 21 movably connected to the inside of the shell 22 and connected to the control board 26, a groove 23 opened at one end of the shell 22 for accommodating the shell 11, a waterproof ring 24 fixed to the inner wall of the groove 23, a charging part 25 fixedly connected to the inside of the shell 22 and electrically connected to the battery 28, and a waterproof cover 27 clamped on the lower end of the shell 22.

[0049] By adopting the above technical scheme, by manually applying pressure to the push cover 12 and the push cover 21, the push cover 12 and the push cover 21 can respectively contact the switch contacts on the control board 15 and the control board 26, so that the motor 14 and the gas-liquid supply unit 7 can be controlled to work respectively through the control board 15 and the control board 26. Both the control board 15 and the control board 26 are PCB circuit boards, which belong to mature existing technologies and are not described here. The motor 14 is a vibration motor. When the motor 14 is working, its vibration output shaft can drive the insertion rod 1 31 and the bristles 32 fixed on the insertion rod 1 31 to vibrate at high frequency through the transmission member 13, so as to realize the function of vibrating and brushing the teeth. When the transmission member 13 is inserted into the slot 33 in the insertion rod 1 31, the hollow flange 132 is inserted into the flange groove 35. At this time, one end of the pipeline 3 5 can be connected to one end of the pipeline 1 34 inside the insertion rod 1 31. When the pump body 73 is working, it can The water in the water tank 72 can be pumped into the metal pipe 74. When the micro air pump 71 is working, gas can be pumped into the metal pipe 74. The water and gas in the metal pipe 74 can enter the pipe three 5 through the pipe two 4, enter the pipe one 34 from the pipe three 5, and then be discharged from the pipe one 34 through the hose 39 into the output pipe 38, and finally be discharged from the output pipe 38. The pump body 73 and the micro air pump 71 can work at the same time, so as to pump the gas into the water flow, so as to achieve the effect of simultaneous flushing by spraying water and jetting. After the water and gas are mixed, an effect similar to that of bubble water is produced. The bursting of bubbles in the water will bring a stronger impact force, which is helpful to remove stubborn dirt on the surface of teeth and in the gaps between teeth. At the same time, the mixed jet can make the water flow softer, which can reduce the stimulation and damage to the gums while maintaining the cleaning effect, and improve the comfort of use. The pump body 73 and the micro air pump 71 can also work separately, so as to achieve the function of spraying water or jetting alone.

[0050] like Figure 7 , 10 - Fig.13As shown, the block 37 is rotatably connected to the inner wall of the movable groove 36, and the insert rod 31 is internally connected with an adjusting component 9 for driving the block 37 to rotate, and the adjusting component 9 includes a seat body 91 movably inserted in the block 37, a connecting rod 92 with one end rotatably connected to the outside of the seat body 91, a seat body 93 movably inserted at one end of the connecting rod 92, a frame 94 rotatably connected to the outside of the seat body 93, and an insert rod 95 fixed to the lower end of the frame 94, and the connecting rod 92 is rotatably connected to the inside of the insert rod 31, and the shell 11 is internally connected with a driving component 10 for driving the insert rod 95 to move up and down.

[0051] The inside of the plug rod 1 31 is provided with a movable groove 2 96 for the movement of the plug rod 2 95, and the outside of the plug rod 2 95 is movably sleeved with two waterproof sleeves 2 97, the outer surface of the waterproof sleeve 2 97 is fixedly connected to the inner wall of the movable groove 2 96, and the inside of the plug rod 1 31 is also provided with a drainage groove 98 connected to the movable groove 2 96, and the opening of the drainage groove 98 is plugged with a rubber plug 99.

[0052] The driving assembly 10 includes a motor 101 fixedly connected to the inside of a shell 11, an incomplete gear 102 rotatably connected to the inside of the shell 11 and connected to the output shaft of the motor 101, a movable plate 103 movably connected to the inside of the shell 11, a tooth groove 104 opened in the movable plate 103 and meshing with the incomplete gear 102, and a clamping portion 105 fixedly connected to the upper end of the movable plate 103. The lower end of the insert rod 95 is provided with a clamping groove 951 matching the clamping portion 105.

[0053] By adopting the above technical solution, when the second motor 101 works to drive the incomplete gear 102 to rotate, the incomplete gear 102 can sequentially contact and mesh with the two sets of tooth keys on the inner wall of the tooth groove 104, thereby driving the movable plate 103 and the clamping part 105 to move up and down. The clamping part 105 is clamped in the second plug rod 95. When the clamping part 105 moves up and down, it can drive the second plug rod 95 and the frame 94 to move up and down. When the frame 94 moves upward, the frame 94 can The end of the connecting rod 92 connected to the seat body 2 93 is lifted upward, so that the end of the connecting rod 92 connected to the seat body 1 91 moves downward, thereby driving the block 37 to rotate clockwise inside the movable groove 1 36. When the frame 94 moves downward, the frame 94 drives the end of the connecting rod 92 connected to the seat body 2 93 to move downward, so that the end of the connecting rod 92 connected to the seat body 1 91 is tilted upward, thereby driving the block 37 to rotate counterclockwise inside the movable groove 1 36. The connecting rod 92 acts as a lever. The function of the water spray and air jet is to adjust the direction of the block 37 and the output tube 38 by adjusting the component 9, so as to adjust the spray angle of the water spray and the air jet. By adjusting the angle, the water flow or air flow can better enter the difficult-to-clean areas such as the gaps between teeth, under the gum line, and behind the teeth, and assist the bristles 32 to perform deep cleaning and clean the entire oral cavity more comprehensively. The adjustable angle water spray and air jet functions make cleaning more targeted, and the brushing time can be shortened by reducing repeated operations. The user does not have to repeatedly adjust the position of the brush head, and a wider cleaning range can be covered by adjusting the spray angle; the waterproof sleeve 2 97 is used to prevent water from entering the active groove 2 96 from the active groove 1 36. Two waterproof sleeves 2 97 are provided and a drainage groove 98 is provided between the two waterproof sleeves 2 97, which can achieve a double waterproof effect. If water enters between the two waterproof sleeves 2 97, the rubber plug 99 is pulled out, and the plug rod 1 31 is tapped, and the water can be discharged from the drainage groove 98.

[0054] like Fig. 9 and Fig.14 As shown, the metal pipeline 74 includes a speed-up and mixing-aiding section 8 and two metal pipes respectively connected to the two ends of the speed-up and mixing-aiding section 8, and the speed-up and mixing-aiding section 8 includes an inlet end 81 and a diffusion end 83 respectively connected to the two metal pipes, a throat 82 connecting the inlet end 81 and the diffusion end 83, and a spiral guide flange 84 integrally formed on the inner walls of the throat 82 and the diffusion end 83. The output end of the micro air pump 71 is connected to the throat 82 through a one-way valve 79, and the output end of the pump body 73 is connected to one of the metal pipes through the one-way valve 79, and one end of the other metal pipe is connected to pipeline 2 4.

[0055] By adopting the above technical scheme, when the water flow or the water-gas mixture passes through the speed-up and mixing-aiding section 8, the water flow first enters from the inlet end 81, generates negative pressure in the throat 82, mixes with the gas discharged from the micro air pump 71, and then is discharged from the diffusion end 83. The spiral guide flange 84 on the diffusion end 83 and the inner wall of the throat 82 can promote the water flow to move in a spiral motion, so that the bubbles are more evenly distributed in the water flow. The small and uniform bubbles increase the impact force and stability of the mixture, further enhance the gas-liquid mixing effect, make the gas distribution more even, generate fine small bubbles, and help to increase the gas-liquid contact area. At the same time, the spiral guide flange 84 guides the gas-liquid mixed flow into a turbulent state, enhances the impact force of the fluid, and the turbulence can better hit the target surface, such as the tooth surface, tooth gaps and other parts. The gas-liquid mixed flow generated after the bubbles are compressed and accelerated will produce a bubble rupture effect when it contacts the tooth surface, thereby forming a tiny shock wave to help clean stubborn dirt.

[0056] like Fig. 9 and Fig.15 As shown, an ultrasonic generator 77 is also fixedly connected to the interior of the shell 22, and the output end of the ultrasonic generator 77 is connected to one end of one of the metal pipes. The pipeline 1 34, the pipeline 2 4 and the pipeline 3 5 all include a tube body 41, two metal joints 42 symmetrically fixed at both ends of the tube body 41, a conductive strip 43 fixedly connected to the inside of the tube body 41 and connected to the metal joints 42, a conductive sheet 44 fixedly connected to the inside of the tube body 41 and connected to the conductive strip 43, and a tube cavity 45 opened in the inside of the tube body 41, and one end of the conductive sheet 44 extends into the tube cavity 45.

[0057] A detergent storage box 75 is also fixedly connected to the interior of the shell 22, and the input end of the pump body 73 is connected to a three-way valve 76, and the other two ends of the three-way valve 76 extend into the water tank 72 and the detergent storage box 75 respectively. The outside of the metal pipe 74 is sheathed with an electric heating jacket 78.

[0058] By adopting the above technical solution, the ultrasonic generator 77 (which belongs to mature existing technology and will not be described here) can work to act on the metal pipe 74 with ultrasonic waves. Since the two ends of the pipe 2 4 are respectively connected to the metal pipe 74 and the pipe 3 5, and one end of the pipe 3 5 is connected to the pipe 1 34, the ultrasonic wave can be transmitted to the conductive strips 43 in the pipe 2 4, the pipe 3 5 and the pipe 1 34 through the metal pipe 74, and transmitted to the conductive sheet 44 through the conductive strip 43, and then transmitted to the liquid in the tube cavity 45 through the conductive sheet 44. Multiple conductive sheets 44 are evenly distributed in the tube body 41. The conductive sheets 44 and the conductive strips 43 can be made of metal materials or non-metallic materials (stainless steel), and the ultrasonic wave is transmitted to the inside of the tube body 41. When the ultrasonic wave propagates through the conductive sheets 44 and the conductive strips 43, it will generate vibration and be transmitted to the water flow inside the tube cavity 45, thereby cleaning the inner wall of the tube cavity 45 and acting on the scale on the inner wall of the tube cavity 45 through high-frequency vibration. Vibration will generate tiny bubbles, and the bursting of the bubbles will form local shock waves, thereby stripping off the scale on the inner wall of the tube cavity 45. At the same time, the ultrasonic wave will form rapid vibrations in the water, which will help the water-liquid mixture to produce violent tiny cavitation bubbles. The ultrasonic vibration is superimposed on the water flow, making the impact force of the water flow stronger, and can more effectively remove dirt on the surface and hard-to-reach areas; the water flow in the metal pipe 74 can be heated by the electric heating sleeve 78 so that the water flow can be close to the oral temperature, thereby improving the user experience. The two ports of the three-way valve 76 connected to the water tank 72 and the detergent storage tank 75 are both equipped with control valves. When the control valve in the port connected to the detergent storage tank 75 is opened, the control valve in the port connected to the water tank 72 is closed. At this time, the pump body 73 can pump the cleaning and disinfectant in the detergent storage tank 75 into the pipeline to clean and disinfect the pipeline.

[0059] Instructions for use: Pressing cover 12 and pressing cover 21 can respectively contact the switch contacts on control board 15 and control board 26, so as to respectively control the operation of motor 14 and gas-liquid supply unit 7 through control board 15 and control board 26.
