Description

Technical Field

[0001] The invention relates to the technical field of oral cleaning, and in particular to an oral cleaning and care device. Background Art

[0002] With the deepening of modern knowledge about oral health, the innovation and development of oral cleaning tools has become an important trend in the market. The cleaning effect of traditional manual toothbrushes depends largely on the user's brushing skills, including the control of force direction, frequency and angle. These factors vary in stability between individuals, thus affecting the cleaning effect. The complex morphology of the dentition is often difficult to reach with a manual toothbrush, resulting in incomplete removal of plaque biofilm. These residual plaques will form tartar after mineralization, becoming the main risk factor for periodontal disease.

[0003] The emergence of electric toothbrushes has significantly improved the efficiency of tooth cleaning by driving the bristles to vibrate at high frequencies through motors. However, most of the mainstream electric toothbrushes on the market currently use a fixed brush head design. Although this design can achieve high-frequency vibration and effectively enhance the cleaning power, its mechanical stripping effect is still insufficient when facing some stubborn plaque, such as the interproximal gap deep in the dentition and the posterior triangular area of ​​the molars, because the plaque in these areas is often more stubborn and requires more flexible and varied cleaning methods and stronger targeting to be effectively removed. Fixed brush heads are difficult to fully adapt to these complex and changeable tooth shapes due to their fixed vibration modes and angles, resulting in unsatisfactory cleaning effects. Although electric toothbrushes have made significant progress compared to manual toothbrushes, there is still room for improvement in meeting the needs of deep cleaning of teeth.

[0004] Therefore, in view of this, the inventor proposes an oral cleaning and care device to solve the above technical problems. Summary of the invention

[0005] The object of the present invention is to provide an oral cleaning and care device to solve the problem that the existing oral cleaning and care devices are insufficient in terms of teeth cleaning.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] An oral cleaning and care device comprises a body and a toothbrush, wherein the toothbrush is mounted on the body;

[0008] The toothbrush comprises a brush shell, a brush rod, a first brush head and a second brush head, wherein the first brush head and the second brush head are arranged on the brush shell, one end of the brush rod is connected to the brush shell, and the other end of the brush rod is connected to the body;

[0009] A liquid storage cavity and a containing cavity are provided in the body, and the liquid storage cavity is used to store flushing liquid;

[0010] A push rod with a hollow structure is movably arranged in the brush rod;

[0011] A driving assembly is disposed in the accommodating chamber, and the driving assembly is connected to the push rod. The flushing liquid in the liquid storage chamber can flow through the push rod through the driving assembly into the first brush head and the second brush head, and be sprayed out from the first brush head and the second brush head.

[0012] At the same time, the driving assembly drives the first brush head to rotate forward or reverse periodically through the push rod.

[0013] According to the above technical solution, the toothbrush is composed of a brush shell, a brush rod, a first brush head and a second brush head, wherein the brush shell serves as a supporting structure, the brush rod connects the brush shell and the body, and the first brush head and the second brush head are responsible for directly contacting the teeth for cleaning; a liquid storage chamber and a receiving chamber are specially arranged in the body, the main function of the liquid storage chamber is to store the flushing liquid, which can be mouthwash, disinfectant or other liquids that help oral cleaning, and the receiving chamber is used to install the drive assembly, which is closely connected to the hollow structure push rod in the brush rod. When the device is started, the drive assembly starts to work, which can not only generate power to drive the push rod to reciprocate in the brush rod, but also guide the flushing liquid in the liquid storage chamber to the push rod, and then transport it to the first brush head and the second brush head. More advanced is that the drive assembly can drive the first brush head to perform periodic forward or reverse rotation while pushing the push rod to move. This rotation action combined with the spraying of the flushing liquid can more effectively remove stains and dental plaque on the surface of the teeth, especially for hard-to-reach areas such as the gaps between teeth, the cleaning effect is more significant;

[0014] The second brush head is movably mounted on the brush housing. When the push rod moves back and forth, it drives the driving bar to move. Due to the inclined setting of the spring piece, the driving bar can drive the angle of the second brush head to change. The second brush head can also receive the rinse liquid from the push rod and spray the rinse liquid evenly on the teeth and between the teeth, further enhancing the cleaning effect.

[0015] Furthermore, a partition plate and a mounting plate are provided in the body, the partition plate divides the inside of the body into the liquid storage chamber and the accommodating chamber, and the partition plate is fixed to the mounting plate;

[0016] The driving assembly comprises a boosting structure arranged on the mounting plate, the water inlet end of the boosting structure is connected to a water inlet pipe group, and the water outlet end of the boosting structure is sealingly and slidably connected to the push rod.

[0017] According to the above technical solution, inside the body, the space is divided into a liquid storage chamber and a receiving chamber by a partition, and the two are independent of each other; the mounting plate is fixed on the partition to provide a stable mounting base for the drive assembly. The boost structure in the drive assembly is cleverly mounted on the mounting plate, and its water inlet end is connected to the liquid storage chamber through a water inlet pipe group to ensure that the flushing liquid can smoothly enter the boost structure, and the water outlet end of the boost structure is sealed and slidably connected to the push rod. In this way, under the action of the boost structure, the flushing liquid can be pressurized and pushed into the push rod, and then flow to the first brush head and the second brush head of the toothbrush, ensuring the effective delivery of the flushing liquid and achieving the pressure boosting effect of the flushing liquid.

[0018] Furthermore, the boosting structure comprises a boosting housing, a boosting cylinder arranged in the boosting housing, and a piston sheet sealingly and slidably connected in the boosting cylinder, and a boosting chamber is formed in the boosting housing;

[0019] A first connecting rod is fixedly arranged on the piston plate, and an end of the first connecting rod extends out of the boosting cylinder;

[0020] The piston plate divides the interior of the boost cylinder into a first boost chamber and a second boost chamber. The boost cylinder is provided with an inlet flow channel A and an outlet flow channel B connected to the first boost chamber. Both the inlet flow channel A and the outlet flow channel B are provided with a one-way valve diaphragm.

[0021] The boost cylinder is provided with an inlet flow channel C and a plurality of outlet flow channels D which are connected to the second boost chamber, and the inlet flow channel C and each of the outlet flow channels D are provided with a one-way valve diaphragm;

[0022] Wherein, the outlet flow channel B and each of the outlet flow channels D are communicated with the pressurizing chamber.

[0023] According to the above technical solution, a first connecting rod is fixedly arranged on the piston plate, and a boosting cylinder is extended from its end. When the driving mechanism is started, it drives the piston plate to reciprocate in the boosting cylinder through the first connecting rod; on the first boosting chamber, the boosting cylinder is provided with an inlet flow channel A and an outlet flow channel B, both of which are provided with a one-way valve diaphragm. When the piston plate moves toward the second boosting chamber, the one-way valve diaphragm of the inlet flow channel A opens, allowing external air to enter the first boosting chamber; at the same time, the one-way valve diaphragm of the outlet flow channel B closes to prevent the backflow of the flushing liquid in the boosting chamber; when the piston plate moves toward the first boosting chamber, the situation is the opposite, the one-way valve diaphragm of the inlet flow channel A closes, and the one-way valve diaphragm of the outlet flow channel B opens, allowing the compressed gas in the first boosting chamber to enter the boosting chamber. At this time, the gas pressure in the boosting chamber gradually increases, providing power for the pressurization of the flushing liquid.

[0024] At the same time, on the second boost chamber, the boost cylinder also opens an inlet flow channel C and several outlet flow channels D, which are also provided with a one-way valve diaphragm. The functions of these channels are similar to those of the channels on the first boost chamber, but their opening and closing timings are opposite to those of the channels on the first boost chamber; their purpose is also to further enhance the air pressure in the boost chamber through the reciprocating motion of the piston plate. Compared with the prior art, this alternating operation not only improves the impact efficiency of the flushing liquid, realizes efficient pressurization of the flushing liquid, ensures that the flushing liquid can reach the toothbrush head with sufficient pressure and flow, improves the cleaning effect, but also effectively balances the air pressure distribution in the boost cylinder and reduces energy loss.

[0025] Further, the driving assembly includes a motor arranged on the mounting plate and a rotating shaft rotatably connected to the mounting plate, a disc gear and a shifting cylinder are arranged on the rotating shaft, the disc gear is arranged coaxially with the rotating shaft, a first gear is connected to the output shaft of the motor, and the first gear is meshed with the disc gear;

[0026] The driving cylinder is eccentrically arranged with respect to the rotating shaft;

[0027] The driving cylinder is sleeved with a first sliding member, and the first sliding member is connected to the first connecting rod.

[0028] According to the above technical solution, after the motor is started, its output shaft drives the first gear to rotate. Since the first gear is meshed with the disc gear, the disc gear also rotates accordingly. The disc gear is coaxially arranged with the rotating shaft, so the rotating shaft also rotates accordingly. The eccentrically arranged toggle cylinder on the rotating shaft makes a circular motion as the rotating shaft rotates. Since the contact surface of the first sliding member sleeved on the toggle cylinder is constantly changing with the toggle cylinder, it will make a reciprocating sliding motion along its axial direction under the drive of the toggle cylinder. The first sliding member is connected to the first connecting rod, so the first connecting rod will also move with the reciprocating motion of the first sliding member, thereby driving the piston plate in the boosting structure to reciprocate in the boosting cylinder; the rotary motion of the motor is cleverly converted into the reciprocating linear motion of the piston plate, without the need for an additional conversion mechanism, the structure is more compact, and the energy loss is smaller; at the same time, since the toggle cylinder is eccentrically arranged with the rotating shaft, the reciprocating motion of the first sliding member is more stable, thereby ensuring the stability and continuity of the motion of the piston plate, and improving the reliability and durability of the entire device.

[0029] Furthermore, a second sliding member is sleeved on the driving cylinder.

[0030] A pull rod is slidably arranged on the supercharging housing, one end of the pull rod is connected to a flexible rod, the flexible rod is connected to the second sliding member, and the other end of the pull rod is fixedly connected to the push rod.

[0031] According to the above technical solution, when the motor drives the rotating shaft to rotate, the driving cylinder will make a circular motion accordingly. Not only will the first sliding member mounted on the driving cylinder be driven to make a reciprocating sliding motion, thereby driving the first connecting rod and the piston plate to move, but the second sliding member will also make a corresponding sliding motion under the drive of the driving cylinder, driving the pull rod and the push rod to move back and forth left and right.

[0032] Furthermore, the water inlet pipe group includes a water inlet pipe, a first adapter and a second adapter, the water inlet pipe, the first adapter and the second adapter are connected to each other, the water inlet pipe is located in the liquid storage cavity, and the second adapter is connected to the pressurization chamber.

[0033] According to the above technical solution, the first adapter and the second adapter are provided to ensure that the water inlet pipe group can flexibly and stably connect the liquid storage chamber and the pressurization chamber, ensuring that the flushing liquid can flow smoothly and efficiently into the pressurization chamber, thereby improving the reliability and practicality of the entire device.

[0034] Furthermore, a connecting shaft is rotatably connected in the brush housing, a second gear is fixedly arranged on the connecting shaft, and the second gear is fixed to the first brush head;

[0035] Embedding holes are provided on both sides of the brush shell, and connecting protrusions adapted to the embedding holes are provided on both sides of the second brush head, and the two connecting protrusions are located in the middle of the second brush head.

[0036] Furthermore, a second connecting rod is provided on a side of the push rod away from the machine body, the second connecting rod is connected to a driving bar, the driving bar is in a U-shaped structure, and a plurality of teeth are provided on the driving bar; the driving bar is meshed with the second gear;

[0037] A spring sheet is arranged on the top of the second brush head, the spring sheet is arranged obliquely, and the bottom of the driving bar is in sliding contact with the spring sheet.

[0038] According to the above technical solution, when working, the push rod reciprocates under the action of external force, and a second connecting rod is provided on the side of the push rod away from the body. The second connecting rod is connected to a driving bar with a U-shaped structure, and a plurality of teeth are provided on the driving bar, which mesh with the second gear on the connecting shaft that is rotatably connected in the brush housing. Therefore, when the push rod reciprocates, the driving bar is driven to move through the second connecting rod, thereby driving the second gear to rotate. Since the second gear is fixed to the first brush head, the rotation of the second gear will drive the first brush head to rotate together, thereby realizing the scrubbing function. At the same time, the bottom of the driving bar is in sliding contact with the shrapnel that is obliquely arranged on the top of the second brush head. As the driving bar reciprocates, it will continuously squeeze and release the shrapnel. This dynamic action can cause the second brush head to produce a slight vibration or trembling effect, further enhancing the scrubbing effect.

[0039] In addition, embedding holes are provided on both sides of the brush housing, and connecting protrusions matching the embedding holes are provided on both sides of the second brush head. This design not only enables the second brush head to be firmly mounted on the brush housing, but also facilitates disassembly and replacement. When the second brush head is worn or needs to be cleaned, the user can easily remove it from the embedding hole for necessary maintenance or replacement.

[0040] Furthermore, a spray cavity is formed inside the brush housing, and a plurality of spray holes are provided on the first brush head and the second brush head, and each of the spray holes is connected to the spray cavity;

[0041] The push rod is provided with a plurality of flow holes, and the flow holes are communicated with the spray chamber.

[0042] According to the above technical solution, during operation, when the push rod is subjected to an external driving force to reciprocate, a number of flow holes on the push rod will be connected to the spray chamber, and these flow holes serve as a delivery channel for the flushing liquid, so that the flushing liquid can flow smoothly into the spray chamber. The spray chamber serves as a space for storing and distributing the flushing liquid, ensuring that the flushing liquid can be evenly distributed and supplied to the first brush head and the second brush head; the first brush head and the second brush head are both provided with a number of spray holes, which are connected to the spray chamber; therefore, when the flushing liquid enters the spray chamber, it will be evenly sprayed onto the brush head through these spray holes, thereby flushing and scrubbing the surface to be cleaned. This design not only improves the efficiency of the use of the flushing liquid, but also ensures the wetness and cleaning effect during the scrubbing process, providing users with a more efficient and convenient cleaning experience.

[0043] Furthermore, a liquid injection switch is provided on the machine body in an openable and closable manner, and the liquid injection switch is used to open or close the liquid storage chamber.

[0044] According to the above technical solution, the injection switch is openably arranged on the body to control the opening or closing of the liquid storage chamber. When the flushing liquid needs to be added or replaced, the user only needs to open the injection switch to easily inject the flushing liquid into the liquid storage chamber. After the operation is completed, the injection switch is closed to ensure the sealing of the liquid storage chamber and prevent the flushing liquid from leaking.

[0045] Beneficial effects of the present invention:

[0046] 1. The present invention forms a dual cleaning mode of mechanical friction + fluid flushing through the linkage design of periodic positive and reverse rotation of the first brush head and angle change of the second brush head (sliding contact between the drive bar and the spring piece), combined with the injection of the rinse liquid; the rotating first brush head can go deep into the gaps between teeth to scrape away soft plaque, and the high-pressure pulse rinse liquid booster structure can increase the pressure to penetrate narrow gaps between teeth, clean the interproximal gaps deep in the dentition, the posterior triangular area of ​​the molars and other areas, and improve the plaque removal rate.

[0047] 2. By combining the dual brushing design of the first brush head and the second brush head, and connecting the flow hole on the push rod with the spray chamber, the rinse liquid can be evenly sprayed on the brush head and deep into the teeth for cleaning. The combination of the rotating brushing of the first brush head and the vibration effect of the second brush head can more effectively remove stains and plaque on the tooth surface and in the teeth, significantly improving the cleaning effect of the teeth.

[0048] 3. The built-in booster structure of the device achieves efficient pressurization of the flushing liquid through the reciprocating motion of the piston plate, which not only improves the impact efficiency of the flushing liquid, but also ensures that the flushing liquid can reach the toothbrush head with sufficient pressure and flow. Especially when cleaning between teeth, it can more effectively flush away food residues and bacteria hidden in the teeth, further improving the cleaning effect.

[0049] 4. The second brush head is matched with the embedding hole of the brush shell through the connecting protrusion, realizing a stable and easy-to-disassemble installation method. This design not only makes it more convenient and quick for users to replace or clean the brush head, but also helps to extend the service life of the entire device. At the same time, the combined use of the first brush head and the second brush head increases the washing area of ​​oral cleaning, improves the cleaning efficiency, and provides users with a more comprehensive and detailed oral cleaning experience.

[0072] The driving component 4 includes a boosting structure 7 arranged on the mounting plate 6, the water inlet end of the boosting structure 7 is connected to the water inlet pipe group 8, and the water outlet end of the boosting structure 7 is sealed and slidably connected to the push rod 3; the boosting structure 7 in the driving component 4 is arranged on the mounting plate 6, and its water inlet end is connected to the liquid storage chamber 101 through the water inlet pipe group 8, ensuring that the flushing liquid can smoothly enter the boosting structure 7, and the water outlet end of the boosting structure 7 is sealed and slidably connected to the push rod 3, so that under the action of the boosting structure 7, the flushing liquid can be pressurized and pushed into the push rod 3, and then flow to the first brush head 23 and the second brush head 24 of the toothbrush 2, which ensures the effective delivery of the flushing liquid and also achieves the pressure boosting effect of the flushing liquid.

[0073] As a preferred embodiment, Fig.11As shown, the boost structure 7 includes a boost housing 71, a boost cylinder 72 disposed in the boost housing 71, and a piston sheet 73 sealingly and slidably connected in the boost cylinder 72. A boost chamber 711 is formed in the boost housing 71.

[0074] like Figure 8 and Fig.11 As shown, a first connecting rod 74 is fixedly disposed on the piston plate 73, and the end of the first connecting rod 74 extends out of the boosting cylinder 72;

[0075] The piston plate 73 divides the interior of the boost cylinder 72 into a first boost chamber 721 and a second boost chamber 722. The boost cylinder 72 is provided with an inlet flow channel A723 and an outlet flow channel B724 which are connected to the first boost chamber 721. The inlet flow channel A723 and the outlet flow channel B724 are both provided with a one-way valve diaphragm. It should be noted that the one-way valve diaphragm of the inlet flow channel A723 and the one-way valve diaphragm of the outlet flow channel B724 have the same structure, but the installation positions are opposite. The one-way valve diaphragm is an existing structure and will not be described in detail.

[0076] The boost cylinder 72 is provided with an inlet flow channel C725 and a plurality of outlet flow channels D726 which are connected to the second boost chamber 722. The inlet flow channel C725 and each outlet flow channel D726 are provided with a one-way valve diaphragm. Similarly, the one-way valve diaphragm of the inlet flow channel C725 and the one-way valve diaphragm of the outlet flow channel D726 have the same structure, but the installation positions are opposite. The one-way valve diaphragm is an existing structure and will not be described in detail.

[0077] Among them, the outlet flow channel B724 and each outlet flow channel D726 are both connected to the pressurization chamber 711.

[0078] According to the above technical solution, a first connecting rod 74 is fixedly provided on the piston plate 73, and the end of the first connecting rod 74 extends out of the boost cylinder 72. When the driving mechanism is started, it drives the piston plate 73 to reciprocate in the boost cylinder 72 through the first connecting rod 74. On the first boost chamber 721, the boost cylinder 72 is provided with an inlet flow channel A723 and an outlet flow channel B724, both of which are provided with a one-way valve diaphragm. When the piston plate 73 moves toward the second boost chamber 722, the one-way valve diaphragm of the inlet flow channel A723 opens, allowing external air to enter the first boost chamber 721; at the same time, the one-way valve diaphragm of the outlet flow channel B724 closes to prevent the backflow of the flushing liquid in the boost chamber 711; when the piston plate 73 moves toward the first boost chamber 721, the situation is the opposite, the one-way valve diaphragm of the inlet flow channel A723 closes, and the one-way valve diaphragm of the outlet flow channel B724 opens, allowing the gas in the first boost chamber 721 to enter the boost chamber 711. At this time, the gas pressure in the boost chamber 711 gradually increases, providing power for pressurizing the flushing liquid.

[0079] At the same time, on the second boost chamber 722, the boost cylinder 72 also opens an inlet flow channel C725 and several outlet flow channels D726, which are also provided with a one-way valve diaphragm. The functions of these channels are similar to those of the channels on the first boost chamber 721, but their opening and closing timings are opposite to those of the channels on the first boost chamber 721; their purpose is also to further enhance the air pressure in the boost chamber 711 through the reciprocating motion of the piston plate 73. Compared with the prior art, this alternating double boosting not only improves the impact efficiency of the flushing liquid, realizes the efficient pressurization of the flushing liquid, ensures that the flushing liquid can reach the brush head of the toothbrush 2 with sufficient pressure and flow, improves the cleaning effect, but also effectively balances the air pressure distribution in the boost cylinder 72.

[0080] As a preferred embodiment, Figure 4 , Figure 6 and Fig. 9 As shown, the driving assembly 4 includes a motor 41 disposed on the mounting plate 6 and a rotating shaft 42 rotatably connected to the mounting plate 6, a disc gear 43 and a shifting cylinder 44 are disposed on the rotating shaft 42, the disc gear 43 is coaxially disposed with the rotating shaft 42, a first gear 45 is connected to the output shaft of the motor 41, and the first gear 45 is meshed with the disc gear 43;

[0081] The shifting cylinder 44 is eccentrically arranged with respect to the rotating shaft 42 ; a first sliding member 46 is sleeved on the shifting cylinder 44 , and the first sliding member 46 is connected to the first connecting rod 74 .

[0082] According to the above technical solution, after the motor 41 is started, its output shaft drives the first gear 45 to rotate. Since the first gear 45 is meshed with the disk gear 43, the disk gear 43 also rotates accordingly. The disk gear 43 is coaxially arranged with the rotating shaft 42, so the rotating shaft 42 also rotates accordingly. The eccentrically arranged driving cylinder 44 on the rotating shaft 42 performs eccentric circular motion as the rotating shaft 42 rotates. The first sliding member 46 sleeved on the driving cylinder 44 continuously changes its contact surface with the driving cylinder 44. The first sliding member 46 is connected to the first connecting rod 74. Therefore, it drives the first connecting rod 74 to perform reciprocating sliding motion under the drive of the driving cylinder 44, thereby driving the piston plate 73 in the boosting structure 7 to perform reciprocating motion in the boosting cylinder 72. The rotational motion of the motor 41 is cleverly converted into the reciprocating linear motion of the piston plate 73 without the need for an additional conversion mechanism, and the structure is more flexible. It is more compact and has less energy loss. At the same time, due to the eccentric setting of the driving cylinder 44 and the rotating shaft 42, the reciprocating motion of the first sliding member 46 is smoother, thereby ensuring the stability and continuity of the movement of the piston plate 73, and improving the reliability and durability of the entire device. At the same time, the crank-sliding composite transmission structure (eccentric design of the driving cylinder 44, the first sliding member 46 and the second sliding member 47) is used to convert the rotational motion of the motor 41 into the reciprocating motion of the piston plate 73 (frequency 3-5Hz) and the linear motion of the push rod 3, ensuring high-intensity cleaning with low power consumption.

[0083] In a possible implementation, not only the above-mentioned motor 41, shaft 42, disc gear 43 and other structures are not limited to converting circular motion into reciprocating linear motion, but a hydraulic cylinder can also be directly connected to the first connecting rod 74 to drive the first connecting rod 74 to reciprocate.

[0084] As a preferred embodiment, a second sliding member 47 is sleeved on the dial cylinder 44. Figure 7 As shown, a pull rod 75 is slidably provided on the supercharger housing 71, one end of the pull rod 75 is connected to a flexible rod 76, the flexible rod 76 is connected to the second sliding member 47, and the other end of the pull rod 75 is fixedly connected to the push rod 3. The purpose of the flexible rod 76 is to connect the second sliding member 47 and the pull rod 75, and the flexible rod 76 has a certain anti-torsion property to avoid interference during movement. For the convenience of review and understanding, this structure is similar to the crank piston movement of a fuel engine; according to the above technical solution, when the motor 41 drives the rotating shaft 42 to rotate, the shifting cylinder 44 performs a circular motion, and the first connecting rod 74 is driven by it to perform a reciprocating sliding motion, thereby driving the piston plate 73 to move left and right, and the second sliding member 47 will also perform a corresponding movement under the drive of the shifting cylinder 44, driving the pull rod 75 and the push rod 3 to move back and forth left and right.

[0085] As a preferred embodiment, Figure 7 and Fig.13 As shown, the water inlet pipe assembly 8 includes a water inlet pipe 81, a first adapter 82 and a second adapter 83. The water inlet pipe 81, the first adapter 82 and the second adapter 83 are interconnected, the water inlet pipe 81 is located in the liquid storage chamber 101, and the second adapter 83 is connected to the pressurization chamber 711. The first adapter 82 and the second adapter 83 are provided to ensure that the water inlet pipe assembly 8 can flexibly and stably connect the liquid storage chamber 101 and the pressurization chamber 711, ensure that the flushing liquid can flow smoothly and efficiently into the pressurization chamber 711, and improve the reliability and practicality of the entire device.

[0086] In a possible implementation, a booster pump (not shown) is provided on the water inlet pipe 81 , and the booster pump is used to suck the flushing liquid in the liquid storage chamber 101 into the water inlet pipe 81 , so that the flushing liquid cleans the oral cavity.

[0087] As a preferred embodiment, Figure 5 As shown, a connecting shaft 211 is rotatably connected in the brush housing 21, a second gear 212 is fixedly provided on the connecting shaft 211, and the second gear 212 is fixed to the first brush head 23;

[0088] Embedding holes 214 are formed on both sides of the brush housing 21 , and connecting protrusions 215 matching the embedding holes 214 are formed on both sides of the second brush head 24 . The two connecting protrusions 215 are located in the middle of the second brush head 24 .

[0089] The push rod 3 is away from the side of the body 1 ( Figure 5 A second connecting rod 216 is provided on the left side of the brush head 24, and the second connecting rod 216 is connected to a driving bar 213, the driving bar 213 is in a U-shaped structure, and a plurality of teeth are provided on the driving bar 213; the driving bar 213 is meshed with the second gear 212; a spring piece 217 is provided on the top of the second brush head 24, the spring piece 217 is inclined, and the bottom of the driving bar 213 is in sliding contact with the spring piece 217.

[0090] According to the above technical solution, when working, the push rod 3 reciprocates left and right under the action of the driving assembly 4, and drives the driving bar 213 to move through the second connecting rod 216, thereby driving the second gear 212 to rotate. Since the second gear 212 is fixed to the first brush head 23, the rotation of the second gear 212 will drive the first brush head 23 to rotate together, thereby realizing the brushing function. At the same time, the bottom of the driving bar 213 is in sliding contact with the elastic sheet 217 inclined at the top of the second brush head 24. As the driving bar 213 reciprocates, it will continuously squeeze and release the elastic sheet 217. This dynamic action can cause the second brush head 24 to change its angle around the connecting protrusion 215, produce a slight vibration or trembling effect, and further enhance the brushing effect. The second brush head adopts a movable connection structure (embedded hole 214 + connecting protrusion 215), which produces a ±15° swing angle when the push rod 3 reciprocates, and cooperates with the atomization spray of the spray hole 219 to clean the gap between teeth.

[0091] At the same time, the present application combines the first brush head 23 and the second brush head 24 to increase the washing area of ​​oral cleaning, making it more convenient for users to use; through the linkage design of the periodic forward and reverse rotation of the first brush head 23 and the angle change of the second brush head 24 (the driving bar 213 and the spring 217 are in sliding contact), combined with the flushing liquid injection, a dual cleaning mode of mechanical friction + fluid flushing is formed; the double chamber (first boost chamber 721 and second boost chamber 722) alternating pressurization technology is used to form a continuous and stable pressure gradient, avoiding the intermittent impact of traditional pulsed water flow that causes gum sensitivity. The rotating first brush head 23 is combined with the second brush head 24 to scrub and scrape away dental plaque, and the fluid flushing wash improves the plaque removal rate.

[0092] As a preferred embodiment, Fig.10 As shown, a spray chamber 218 is formed inside the brush housing 21, a plurality of spray holes 219 are provided on the first brush head 23 and the second brush head 24, and each spray hole 219 is connected to the spray chamber 218; a plurality of flow holes 301 are provided on the push rod 3, and the flow holes 301 are connected to the spray chamber 218.

[0093] According to the above technical solution, when the push rod 3 is driven by an external driving force to reciprocate, the plurality of flow holes 301 provided on the push rod 3 will be connected to the spray chamber 218, and these flow holes 301 serve as a delivery channel for the flushing liquid, so that the flushing liquid can smoothly flow into the spray chamber 218. The spray chamber 218 is a space for storing and distributing the flushing liquid, ensuring that the flushing liquid can be evenly distributed and supplied to the first brush head 23 and the second brush head 24; the first brush head 23 and the second brush head 24 are both provided with a plurality of spray holes 219, which are connected to the spray chamber 218; therefore, when the flushing liquid enters the spray chamber 218, it will be evenly sprayed onto the brush head through these spray holes 219, thereby flushing and scrubbing the surface to be cleaned. This design not only improves the use efficiency of the flushing liquid, but also ensures the wetness and cleaning effect during the scrubbing process, providing users with a more efficient and convenient cleaning experience.
