DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] Reference Figure 1-Figure 8 As shown, the oral irrigation device of this embodiment mainly comprises a body 1, a first liquid storage container 2 and a second liquid storage container 3. The first liquid storage container 2 and the second liquid storage container 3 are both detachably connected to the body 1.

[0029] The body 1 includes a shell 11 and a water spraying mechanism 12, a water pumping mechanism 13, a first pipe 14 and a locking mechanism 15 arranged on the shell 11. The water spraying mechanism 12 is used to pump out the liquid in the first liquid storage container 2 to achieve the function of flushing the oral cavity. The water pumping mechanism 13 is used to pump the liquid in the external environment into the second liquid storage container 3, for example, sucking the sewage in the oral cavity during the oral cleaning process. The two ends of the first pipe 14 are respectively connected to the first liquid storage container 2 and the second liquid storage container 3, and its function is to realize the liquid circulation between the two liquid storage containers when necessary, forming a larger liquid storage space to meet different usage requirements. The locking mechanism 15 is used to squeeze the middle part of the first pipe 14 to close the middle part of the first pipe 14. The operation of the locking mechanism 15 can release the closure of the middle part of the first pipe 14, thereby flexibly controlling the connection state between the two liquid storage containers.

[0030] In this embodiment, the locking mechanism 15 includes a pressure-bearing member 151, an extrusion assembly 152, and a control assembly 153. The pressure-bearing member 151 is fixedly connected to the housing 11 and is located above the middle of the first pipe 14. The extrusion assembly 152 includes a pressure-applying member 1521 and a first elastic member 1522. The pressure-applying member 1521 is longitudinally slidably connected to the housing 11 and is located below the middle of the first pipe 14. The first elastic member 1522 is used to push the pressure-applying member 1521 upwards. The control assembly 153 is used to drive the pressure-applying member 1521 to overcome the elastic force of the first elastic member 1522 and move downwards.

[0031] In the natural state, the first elastic member 1522 will cooperate with the housing 11 to push the pressure member 1521 upward, so that the pressure member 1521 and the pressure receiving member 151 cooperate to squeeze the middle of the first pipe 14, making it closed and preventing the liquid from flowing between the two liquid storage containers. In this state, the two liquid storage containers can be used to store the liquid sucked from the outside to the inside and the liquid pumped from the inside to the outside respectively.

[0032] When the two liquid storage containers need to be connected, the control assembly 153 is operated to drive the pressure member 1521 to overcome the elastic force of the first elastic member 1522 and move downward. The downward movement of the pressure member 1521 can release the squeezing of the first pipe 14, so that the first pipe 14 is unblocked and the liquid flows between the two liquid storage containers. In this state, it is suitable for flushing or suctioning operations alone to meet the needs of large-capacity use.

[0033] The control assembly 153 includes a suspension member 1531 and a pressing member 1532. The suspension member 1531 is rotatably connected to the pressure member 1521 via a rotating shaft 1534 extending left and right. The front and rear sides of the suspension member 1531 respectively have guiding inclined surfaces 15311 inclined forward and backward. The center of gravity of the suspension member 1531 is located below the rotating shaft 1534. This arrangement allows the suspension member 1531 to return to the state before rotation under the action of gravity after the rotation stops. There are two pressing members 1532. Both pressing members 1532 are slidably connected to the housing 11 and are located at the front and rear sides of the suspension member 1531 respectively. The pressing member 1532 can slide toward one side of the suspension member 1531 until it abuts against the guiding inclined surface 15311 on the corresponding side.

[0034] When the pressing pieces 1532 on both sides are pressed inward at the same time, the pressing pieces 1532 slide along the shell 11 and abut against the guide slope 15311 corresponding to the hanging piece 1531, so that the thrust of the two pressing pieces 1532 will act on the guide slope 15311. Under the guiding action of the guide slope 15311, the hanging piece 1531 will drive the pressure piece 1521 to move downward through the rotating shaft 1534 to release the closure of the first pipe 14.

[0035] After the pressing member 1532 is released, the pressure member 1521 will be reset upward under the action of the first elastic member 1522, so that the first pipe 14 can be squeezed and closed. In this process, the pressing member 1532 will be reset to the corresponding position under the pushing action of the guiding inclined surface 15311.

[0036] It is worth mentioning that when only one side of the pressing member 1532 is pressed, after the pressing member 1532 abuts against the hanging member 1531, the hanging member 1531 will flip around the rotating shaft 1534 to make way, thereby preventing accidental touch and avoiding the accidental connection of the two liquid storage containers when they do not need to be connected.

[0037] The locking mechanism 15 also includes a bolt assembly 154, which includes two groups. The two groups of bolt assemblies 154 are respectively located at the front and rear sides of the suspension member 1531 and correspond to the first liquid storage container 2 and the second liquid storage container 3. The bolt assembly 154 includes a bolt 1541, a second elastic member 1542, a support member 1543 and a pull rope 1544. The bolt 1541 slides left and right through the housing 11 close to the corresponding liquid storage container. The support member 1543 is fixedly connected to the housing 11 and is located at the side of the suspension member 1531 close to the corresponding liquid storage container. The second elastic member 1542 is provided between the support member 1543 and the bolt 1541 to push the bolt 1541 toward the corresponding liquid storage container. One end of the pull rope 1544 is fixedly connected to the bolt 1541, and the other end is fixedly connected to the side of the housing 11 away from the corresponding liquid storage container. When the suspension member 1531 is flipped forward and backward, the pull ropes 1544 on the front and rear sides can be pushed upward respectively. The first liquid storage container 2 and the second liquid storage container 3 are both provided with a lock slot 4 for the lock bolt 1541 to be inserted.

[0038] When the user presses only one side of the pressing member 1532, the pressing member 1532 will drive the hanging member 1531 to flip in the direction of being pressed. For example, when the front side pressing member 1532 is pressed, the pressing member 1532 will drive the hanging member 1531 to flip backward. When the hanging member 1531 flips, it will push the pull rope 1544 upward, and the pull rope 1544 will drive the locking bolt 1541 to overcome the elastic force of the second elastic member 1542 and slide in the direction away from the liquid storage container, so that the locking bolt 1541 is pulled out of the locking groove 4 of the liquid storage container, and the connection between the liquid storage container and the machine body 1 is unlocked, so that the user can remove the liquid storage container conveniently; when the hanging member 1531 is reset, under the action of the second elastic member 1542, the locking bolt 1541 will be reinserted into the locking groove 4 of the liquid storage container to achieve the locking of the connection between the liquid storage container and the machine body 1.

[0039] The two support members 1543 are interconnected to form a rectangular structure, and the other end of the pull rope 1544 is fixedly connected to the support member 1543 of another group of locking bolt assemblies 154. This structural design makes the layout of the locking bolt assemblies 154 more reasonable, the force is more uniform, and the stability and reliability of the device are improved.

[0040] In this embodiment, the water spray mechanism 12 includes a second pipe 121, a first water pump and a nozzle 122. One end of the second pipe 121 is connected to the first liquid storage container 2, and the other end is connected to the pumping end of the first water pump, and the nozzle 122 is connected to the pumping end of the first water pump. The first water pump pumps the liquid in the first liquid storage container 2 into the second pipe 121, and sprays it out through the nozzle 122, so as to achieve the function of rinsing the oral cavity.

[0041] In this embodiment, the pumping mechanism 13 includes a third pipe 131, a second water pump and a suction head 132. One end of the third pipe 131 is connected to the second liquid storage container 3, and the other end is connected to the pump outlet of the second water pump, and the suction head 132 is connected to the pump inlet of the second water pump. The second water pump sucks the liquid in the external environment through the suction head 132, and pumps it into the second liquid storage container 3 through the third pipe 131, thereby realizing the suction function of oral sewage and the like.

[0042] In this embodiment, the control assembly 153 further includes a third elastic member 1533, which is used to push the pressing member 1532 to a side away from the hanging member 1531. In this way, after the user releases the pressing member 1532, the pressing member 1532 can automatically reset more smoothly, which is convenient for the next operation.

[0043] In this embodiment, the pressing member 1532 specifically includes a push rod 15321, a stopper 15322, and a button 15323. The push rod 15321 slides forward and backward through the housing 11, the stopper 15322 is fixed to the push rod 15321 and is located inside the housing 11, and the button 15323 is fixed to the push rod 15321 and is located outside the housing 11. The user presses the button 15323 to drive the push rod 15321 and the stopper 15322 to slide inside the housing 11, thereby operating the suspension member 1531.

[0044] In this embodiment, the control assembly 153 further includes a slide bar 1535, the front and rear ends of which are respectively fixed to the front and rear walls of the housing 11, the stopper 15322 is slidably connected to the slide bar 1535, and the third elastic member 1533 is sleeved on the outside of the slide bar 1535 and the two ends are respectively in contact with the two stoppers 15322. The slide bar 1535 provides a guide for the sliding of the stopper 15322 to ensure the sliding stability of the pressing member 1532, and the third elastic member 1533 is sleeved on the slide bar 1535, and by contacting with the stopper 15322, an elastic pushing action on the pressing member 1532 is achieved, so that the pressing member 1532 can be reliably reset.

[0045] When it is necessary to use the first liquid storage container 2 alone for water spraying and flushing, ensure that the first pipe 14 is in a closed state (achieved by using the extrusion assembly 152 of the locking mechanism 15 to make the pressure-applying member 1521 squeeze the middle part of the first pipe 14), start the first water pump of the water spraying mechanism 12, and the first water pump pumps out the liquid in the first liquid storage container 2 through the second pipe 121, and sprays it through the nozzle 122 to flush the oral cavity.

[0046] It is worth mentioning that the end of the nozzle 122 has a shower head, and the connection between the shower head and the nozzle 122 is a hose that can be bent at any angle. The hose is usually made of a material with good flexibility and elasticity, such as silicone or some special polymer materials. The hose may contain a metal wire or other rigid but bendable support structure inside, so that the hose can be bent at will while maintaining a certain shape stability, and will not easily change its shape due to its own gravity or slight external force. In this way, in actual use, the user can more flexibly adjust the angle and position of the nozzle to adapt to different oral parts and cleaning needs. For example, when it is necessary to rinse the teeth deep in the mouth, the shower head can be adjusted to a suitable angle by bending the hose to ensure that the rinsing liquid can accurately reach the target position, thereby improving the cleaning effect. This design increases the convenience and flexibility of the device and further enhances the user's experience in the oral care process. At the same time, the flexible hose connection also makes the nozzle easier to operate during use, reduces the inconvenience caused by the fixed angle, and provides users with a more comfortable and efficient oral care method. Whether it is daily oral cleaning or care for specific oral problems, it can better meet the needs of users.

[0047] When the second liquid storage container 3 needs to be used alone to absorb water, ensure that the first pipe 14 is in a closed state, start the second water pump of the pumping mechanism 13, and the second water pump sucks liquid such as sewage in the oral cavity through the suction head 132 and pumps it into the second liquid storage container 3 through the third pipe 131.

[0048] In this embodiment, the second liquid storage container 3 is also provided with an external negative pressure connector, so that when connected to an external negative pressure source, the second liquid storage container 3 can more efficiently extract the liquid in the oral cavity with the help of the external strong negative pressure suction. The connector can be closed by a cover when not in use.

[0049] In this embodiment, the nozzle 122 and the suction head 132 are provided with various sizes and are detachably connected to the housing 11. This design has many advantages.

[0050] For the nozzle 122, nozzles of different sizes can meet the oral structures and cleaning needs of different users. For example, for users or children with narrow oral cavity, a smaller nozzle can more conveniently enter the oral cavity for flushing, while for situations where a large area needs to be flushed, a larger nozzle can improve the flushing efficiency. At the same time, the detachable connection method allows users to easily replace nozzles of different sizes according to actual conditions, and the operation is simple and quick. When the nozzle is blocked or damaged, it can also be easily disassembled for cleaning or replacement, which extends the service life of the entire device and reduces the cost of use.

[0051] For the suction head 132, multiple sizes can better meet the needs of sewage suction in different oral environments. During the oral cleaning process, different degrees of water accumulation or debris may be encountered. A smaller suction head can accurately suck a small amount of local sewage, while a larger suction head is suitable for quickly sucking more sewage. The detachable connection also facilitates the maintenance and replacement of the suction head, ensuring that the pumping mechanism always maintains good working performance when sucking oral sewage, improving the reliability and practicality of the entire oral irrigation device, and providing users with a more flexible and efficient oral care experience.

[0052] When it is necessary to connect the two liquid storage containers to form a larger liquid storage space to meet special needs (for example, a long or large amount of flushing or absorbing water is required), the control component 153 of the locking mechanism 15 is operated. The pressing members 1532 on both sides are pressed at the same time, and the pressing members 1532 push the hanging member 1531 to slide downward, so as to drive the pressure member 1521 to move downward, release the squeeze and closure of the first pipe 14, make the first pipe 14 unobstructed, and realize liquid circulation between the two liquid storage containers to form a larger liquid storage space. At this time, the water spraying mechanism 12 or the water pumping mechanism 13 can be started as needed to perform corresponding operations.

[0053] In this embodiment, the housing 11 has three buttons for adjusting the pressure, which are used to adjust the water extraction and pumping pressure in three levels, so that different pressure settings can meet different oral conditions and care needs. For users with more sensitive oral cavity, or when performing some more delicate oral care operations, a lower pressure level can be selected to avoid excessive stimulation or damage to oral tissues and ensure the comfort of the care process. For situations where strong flushing or absorption of stubborn stains is required, a higher pressure level can provide more powerful water flow power or suction, effectively remove dirt, and improve the cleaning effect.

[0054] By controlling the first pipe 14 through the locking mechanism 15, the two liquid storage containers can be used separately or connected to form a larger liquid storage space as needed. Users can flexibly choose the use of the liquid storage container according to different oral care scenarios and needs, which meets the diverse use needs and improves the applicability and practicality of the device.

[0055] The design of the locking mechanism 15 adopts a push-type operation. By simply pressing the pressing piece 1532, the closing and opening control of the first pipeline 14 and the locking and unlocking of the connection between the liquid storage container and the body 1 can be achieved. The operation is convenient and quick, and the user does not need to perform complicated operating steps, which improves the convenience of use.

[0056] The liquid storage container is detachably connected to the body 1 , and the liquid storage container can be easily removed by controlling the locking mechanism 15 , so that the user can clean, replace or add liquid to the liquid storage container.

[0057] The device integrates water spraying and water pumping functions, which can meet the needs of flushing and sewage suction during oral care. The water spraying mechanism 12 and the water pumping mechanism 13 work through independent pipes and water pumps respectively, ensuring the stability and reliability of their respective functions, and providing users with a comprehensive oral care solution.

[0058] In summary, the oral irrigation device effectively solves the problems existing in existing oral irrigation devices through unique structural design and functional configuration, realizes the flexibility of use and convenience of operation of the two liquid storage containers, and improves the effect of oral care and user experience.

[0059] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
