The handle is provided with a transmission mechanism, which is connected to the brush head to make the brush head reciprocate relative to the handle.

[0005] Furthermore, the infusion channel includes a connecting valve, which has a first chamber, a second chamber, and a third chamber. The first chamber is connected to the second chamber through the third chamber. The first chamber has an inlet port that is connected to the inlet port. The second chamber has a drain port that is connected to the outlet port.

[0006] Furthermore, a drainage section is provided between the third chamber and the first chamber, and a first liquid guide port is provided on the drainage section to connect the third chamber and the first chamber.

The device is then started to control the suction mechanism and transmission mechanism. The suction mechanism provides suction to the infusion channel, drawing external water into the inlet port and transmitting it through the infusion channel to the outlet port, where it is finally sprayed out to form a pulsed water jet, achieving the effect of teeth cleaning. The transmission mechanism provides the power to drive the brush head to swing relative to the handle. When brushing is needed, the transmission mechanism can be activated to make the brush head swing left and right, achieving the brushing effect. During brushing, if clean water or cleaning solution is needed to clean the teeth, the suction mechanism can be activated, and clean water or cleaning solution will be sprayed out from the outlet port, achieving the teeth cleaning effect. This invention can not only perform brushing and teeth cleaning independently, but also, compared to traditional electric toothbrushes or traditional dental irrigators, allows for simultaneous brushing and cleaning, making it convenient and providing a good user experience.

[0035] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1-14 As shown, an electric toothbrush with rinsing function in this embodiment includes a handle 1 and a brush head 2. The brush head 2 is connected to the handle 1. The handle 1 is provided with a liquid inlet port 11, and the brush head 2 is provided with a liquid outlet port 12. The liquid inlet port 11 is connected to the liquid outlet port 12 through a liquid delivery channel 13. The liquid delivery channel 13 is provided with a suction mechanism 14, which is used to provide suction force to the liquid delivery channel 13 to transfer liquid from the liquid inlet port 11 to the liquid outlet port 12 and spray it out. The handle 1 is provided with a transmission mechanism 15, which is connected to the brush head 2 so that the brush head 2 reciprocates relative to the handle 1.

[0038] With the above structural configuration, the present invention can be connected to an external water source through the inlet port 11. Specifically, in use, a flexible tube can be installed at the inlet port and placed in clean water or cleaning solution. When in use, the device is started to control the suction mechanism 14 and the transmission mechanism 15. The suction mechanism 14 provides suction force to the infusion channel 13 to draw external water into the inlet port 11, which is then transmitted through the infusion channel 13 to the outlet port 12. Finally, the water is ejected from the outlet port 12 to form a pulsed water jet, achieving the effect of teeth cleaning. The transmission mechanism 15... The transmission mechanism 15 is used to provide the power to swing the brush head 2 relative to the handle 1. When brushing teeth is needed, the transmission mechanism 15 can be activated to make the brush head 2 swing left and right to achieve the effect of brushing teeth. During the brushing process, when it is necessary to clean the teeth with water or cleaning solution, the suction mechanism 14 can be activated. Under the action of the suction mechanism 14, water or cleaning solution will be sprayed out from the liquid outlet 12 to achieve the effect of cleaning teeth. Compared with traditional electric toothbrushes or traditional dental irrigators, this invention realizes that teeth cleaning can be performed at the same time as brushing teeth, so that brushing and cleaning teeth can be carried out simultaneously, which is convenient to use and provides a good user experience.

[0039] Furthermore, such as Figures 10-14As shown, the infusion channel 13 includes a connecting valve 3. The connecting valve 3 has a first chamber 31, a second chamber 32 and a third chamber 33. The first chamber 31 is connected to the second chamber 32 through the third chamber 33. The first chamber 31 is provided with an inlet 301, which is connected to the inlet port 11. The second chamber 32 is provided with a drain port 302, which is connected to the outlet port 12.

[0040] Specifically, the suction mechanism 14 is connected to the connecting valve 3 to provide a suction force to the connecting valve 3. Under the action of this suction force, the external liquid will be drawn from the inlet port 11 to the inlet port 301. The liquid enters the first chamber 31 from the inlet port 301. The liquid in the first chamber 31 is transferred to the second chamber 32 through the third chamber 33. Finally, it is transferred to the outlet port 12 through the outlet port 302 of the second chamber 32 and sprayed out from the outlet port 12.

[0041] Furthermore, a drainage section 30 is provided between the third chamber 33 and the first chamber 31. The drainage section 30 is provided with a first liquid guide port 51 to connect the third chamber 33 and the first chamber 31. The third chamber 33 is provided with a second liquid guide port 52, which is connected to the second chamber 32. Through the above structural arrangement, the liquid in the first chamber 31 enters the third chamber 33 through the first liquid guide port 51, and the liquid in the third chamber 33 then enters the second chamber 32 through the second liquid guide port 52.

[0042] Specifically, the second chamber 32 is provided with a one-way valve 42, such as a duckbill valve, at the drain port 302. The one-way valve 42 is used to control the opening and closing of the drain port 302. The connecting valve 3 also includes an umbrella valve 43, which has a head 431 and a handle 432. The drainage part 30 is also provided with an insertion hole 53. The handle 432 is fixedly installed in the insertion hole 53 so that the head 431 of the umbrella valve 43 is tightly attached to the first liquid guide port 51 to achieve the sealing of the first liquid guide port 51. In this embodiment, the head 431 of the umbrella valve 43 is made of an elastic material, such as rubber, silicone, etc. Furthermore, as a preferred method, the umbrella handle 432 is also provided with a locking boss 4321. When the umbrella handle 432 is inserted into the insertion hole 53, the locking boss 4321 abuts against the drainage part 30 to fix the umbrella valve 43. Furthermore, a suction port 331 is provided below the third chamber 33. The transmission end of the suction mechanism 14 is connected to the suction port 331 and reciprocates within the suction port 331 to provide suction force to the connecting valve 3, so as to transfer the liquid from the liquid inlet port 11 to the liquid inlet 301 and spray it out from the liquid outlet 302.

[0043] Specifically, in this embodiment, the second chamber 32 is located directly above the first chamber 31, and a plug 41 is provided between the second chamber 32 and the first chamber 31 to prevent direct communication between the second chamber 32 and the first chamber 31. The third chamber 33 is located directly below the first chamber 31, and a partition is formed between the third chamber 33 and the first chamber 31 to form a drainage section 30. The partition is provided with several through holes to form a first liquid guiding hole 51 and an insertion hole 53. The first chamber 31 is connected to the third chamber 33 through the first liquid guiding hole 51 on the partition. Further, the second liquid guiding hole 52 of the third chamber 33 extends upward along the inner sidewall of the third chamber 33 and the outer sidewall of the first chamber 31 to connect with the second chamber 32, and forms a rectangular opening on the inner sidewall of the second chamber 32.

[0044] The following will combine the above structure, and Figure 7 , Figures 12-14 Specifically, this explains how the suction mechanism 14 provides suction force to the connecting valve 3:

[0045] like Figure 7 , Figure 12 As shown, when the equipment is in a stopped state, the head 431 of the umbrella valve 43 is pressed against the first liquid guide hole 51 to block the first liquid guide hole 51, while the one-way valve 42 is closed to block the drain port 302 of the second chamber 32. Through the above structural arrangement, the transmission end of the suction mechanism 14, the third chamber 33 and the second chamber 32 together form the first sealed space.

[0046] When the suction mechanism 14 is activated, the transmission end of the suction mechanism 14 will reciprocate within the suction port 331. When the transmission end of the suction mechanism 14 moves downward, as... Figure 13 As shown, a negative pressure is formed in the first sealed space, which causes the head 431 of the umbrella valve 43 to deform, so that the head 431 moves away from the first liquid guide hole 51, thereby opening the first liquid guide hole 51. The first liquid guide hole 51 connects the first sealed space with the first chamber 31. At this time, a pressure difference is formed between the first chamber 31 and the outside atmosphere, so that the liquid from the outside is drawn into the first chamber 31 through the liquid inlet 301. The liquid in the first chamber 31 then enters the third chamber 33 through the first liquid guide hole 51.

[0047] When the transmission end of the suction mechanism 14 moves upward, such as Figure 10 , 11As shown in Figure 14, the liquid in the third chamber 33 is squeezed by the transmission end of the suction mechanism 14, causing the liquid to be rushed into the second chamber 32 through the second liquid guide hole 52, and then discharged from the drain port 302 through the one-way valve 42 (it should be noted that in this embodiment, the one-way valve 42 is a duckbill valve. When subjected to the impact force, the top of the duckbill valve will open, and the top will close after the impact force is released). Finally, a pulse water column is formed at the liquid outlet 12 and sprayed out. At the same time, during this process, the head 431 of the umbrella valve 43 will rebound and stick tightly to the first liquid guide hole 51 to block the first liquid guide hole 51, thereby preventing the liquid from being discharged from the liquid inlet 301.

[0048] Through the above steps, when the transmission end of the suction mechanism 14 moves downward, the liquid enters the connecting valve 3 through the inlet 301. When the transmission end of the suction mechanism 14 moves upward, the liquid will be discharged from the connecting valve 3 through the outlet 302 in the form of a pulsed water column to provide suction force, thereby transmitting the liquid from the inlet port 11 to the outlet 301, and then forming a pulsed water column ejected from the outlet 302.

[0049] Furthermore, the suction mechanism 14 includes a first drive device 141, a first eccentric wheel 142, and a transmission rod 143. The rotating end of the first drive device 141 is engaged with the first eccentric wheel 142. The first eccentric wheel 142 is provided with a first eccentric part 1421. The transmission rod 143 is sleeved on the first eccentric part 1421 to realize the reciprocating motion of the transmission rod 143.

[0050] Specifically, the first driving device 141 can be a small motor, and the lower end of the transmission rod 143 is provided with an annular sleeve 144, which is sleeved on the first eccentric part 1421. The first driving device 141 is used to drive the first eccentric wheel 142 to rotate. The rotating first eccentric wheel 142 will drive the first eccentric part 1421 to rotate eccentrically, and the eccentrically rotating first eccentric part 1421 will drive the transmission rod 143 to reciprocate.

[0051] Furthermore, the handle 1 also includes a connector 16, which is hollow inside. The lower end of the connector 16 is connected to the drain port 302, and the upper end is connected to the outlet port 12. It is also detachably connected to the brush head 2 to achieve a detachable connection between the brush head 2 and the handle 1.

[0052] With the above-mentioned structural configuration, the pulsed water column ejected from the drain port 302 will be transmitted to the outlet port 12 via the connector 16 and ejected from the outlet port 12.

[0053] Furthermore, the transmission mechanism 15 includes a second drive device 151 and a second eccentric wheel 152. The connecting member 16 is provided with a connecting part 162 and a connecting groove 161. The transmission end of the second drive device 151 is engaged with the second eccentric wheel 152. The second eccentric wheel 152 is provided with a second eccentric part 1521, which is sleeved in the connecting groove 161 to realize the reciprocating oscillation of the connecting member 16.

[0054] Specifically, in this embodiment, the second drive device 151 can be a small motor, the connecting part 162 is arranged perpendicular to the connecting member 16, the second drive device 151 is used to drive the second eccentric wheel 152 to rotate, the rotating second eccentric wheel 152 will drive the second eccentric part 1521 to rotate eccentrically, the eccentrically rotating second eccentric part 1521 will reciprocate in the connecting groove 161, so as to drive the transmission rod 143 to reciprocate.

[0055] Furthermore, the handle 1 also includes a first liquid guide tube 61 and a second liquid guide tube 62. One end of the first liquid guide tube 61 is connected to the liquid inlet port 11 and the other end is connected to the liquid inlet 301. One end of the second liquid guide tube 62 is connected to the liquid outlet 302 and the other end is connected to the lower end of the connector 16. The brush head 2 is hollow inside to form a fourth chamber 34. A connection port 21 is formed at the lower end of the brush head 2 in the fourth chamber 34. The connection port 21 is sleeved on the upper end of the connector 16 to realize the detachable connection between the brush head 2 and the connector 16. The upper end of the brush head 2 is provided with a brush head 22. The brush head 22 is provided with a protrusion 23 integrally formed with the brush head 22. The protrusion 23 is provided with a spray hole 24. The spray hole 24 is connected to the fourth chamber 34 to form a liquid outlet port 12.

[0056] With the above structural configuration, under the action of the suction mechanism 14, liquid will enter the first liquid guide tube 61 through the liquid inlet 11, and be transmitted from the first liquid guide tube 61 to the connecting valve 3 via the liquid inlet 301. The liquid entering the connecting valve 3 will be sprayed out from the liquid outlet 302, and then transmitted to the connector 16 via the second liquid guide tube 62. The pulse water flow in the connector 16 will pass through the fourth chamber 34 and finally be sprayed out from the spray hole 24 of the protrusion 23 to form a pulse water column. When brushing teeth is required, the transmission mechanism 15 can be activated to make the brush head 2 drive the brush head 22 to reciprocate. The brush head 22 can be equipped with bristles and other cleaning parts to achieve the effect of brushing teeth. When rinsing teeth is required, the suction mechanism 14 can be activated. Under the action of the suction mechanism 14, clean water or cleaning liquid will form a pulse water column and be sprayed out from the spray hole 24 to achieve the effect of rinsing teeth.

[0057] Furthermore, in this embodiment, as a preferred embodiment, the handle 1 is equipped with a built-in power supply 71, which is electrically connected to the suction mechanism 14 and the transmission mechanism 15 to provide electrical energy for the operation of the suction mechanism 14 and the transmission mechanism 15. With the above structural arrangement, the handle has a built-in power supply 71, eliminating the need for a separate external power supply during use, making the process safer and eliminating concerns about short circuits or leakage. When the built-in power supply 71 is low on power, an external power source can be connected to charge it, ensuring safe and convenient use.

[0058] To achieve the above-mentioned charging function, a charging port 72 is provided at the bottom of the handle 1. The charging port 72 is electrically connected to the built-in power supply 71. Preferably, the charging port 72 is provided with a detachable seal to prevent liquid from entering the charging port 72 and causing a short circuit.

[0059] Furthermore, the handle 1 in this embodiment is also equipped with a toothbrush switch 73, a flush switch 74, and a flush speed switch 75. The toothbrush switch 73 is used to control the transmission mechanism 15. Specifically, pressing the toothbrush switch 73 can control the opening or closing of the transmission mechanism 15. When the transmission mechanism 15 is working, pressing and holding the toothbrush switch 73 can adjust the working speed of the transmission mechanism 15. When brushing teeth alone is needed, pressing the toothbrush switch 73 will cause the brush head 2 to swing left and right under the action of the transmission mechanism 15 to achieve the effect of brushing teeth. Furthermore, the user can press and hold the toothbrush switch 73 according to personal needs to adjust the speed of the transmission mechanism 15 to control the frequency of the left and right swing of the brush head 2.

[0060] Furthermore, the flush switch 74 is used to control the opening and closing of the suction mechanism 14, and the flush level switch 75 is used to control the working level of the suction mechanism 14. When teeth cleaning is required separately, the flush switch 74 can be pressed to activate the suction mechanism 14. Under the action of the suction mechanism 14, clean water or cleaning fluid will be sprayed out from the outlet port in the form of a pulse water jet to achieve the effect of teeth cleaning. Furthermore, the user can press the flush level switch 75 to control the flushing intensity of the pulse water jet according to personal needs.

[0061] Furthermore, users can achieve simultaneous brushing and teeth cleaning through the above settings. When using, first press the toothbrush switch 73 to start the transmission mechanism 15, which will drive the brush head 2 to swing left and right for brushing. When it is necessary to rinse the teeth during brushing, press the flush switch 74 to start the suction mechanism 14, which will spray clean water or cleaning solution from the outlet port in the form of a pulse water jet for teeth cleaning. During the brushing and teeth cleaning process, users can also select different brushing and teeth cleaning levels according to their personal needs.

[0062] Furthermore, as a preferred method in this embodiment, the buttons of the toothbrush switch 73, flush switch 74, and flush speed switch 75 can be set to different sizes and shapes. When using them, users can distinguish different function buttons according to the different shapes or sizes of the buttons they touch, so as to achieve the effect of blind operation.

[0063] Furthermore, in this embodiment, the present invention also includes a first waterproof component, a second waterproof component, and a third waterproof component. Specifically, the first waterproof component is an "O"-shaped waterproof ring disposed at the bottom of the handle 1 for waterproofing the bottom of the handle 1. The second and third waterproof components are disposed at the connection between the handle 1 and the brush head 2. Specifically, the second waterproof component is tightly fitted onto the connector 16 at the connection between the handle 1 and the brush head 2 to prevent liquid from flowing back into the handle 1 at the connection. The third waterproof component is disposed below the second waterproof component, and the outer side wall of the third waterproof component is tightly attached to the inner side wall of the handle 1 housing to achieve a further waterproofing effect.
