By arranging the oral cleansing liquid capsule 300 at the bottom of the housing 100, the bottom of the housing 100 generally refers to the part below the vertical center line of the housing 100, which allows the use of a larger volume of oral cleansing liquid capsule 300, thereby extending the service time of the product, reducing the frequency of replacing the oral cleansing liquid capsule 300, and improving the user experience; when the oral cleansing liquid capsule 300 is inserted into the capsule accommodating cavity 103, the clamping end of the clamping assembly 400 is clamped in the card slot 303, which can effectively fix the oral cleansing liquid capsule 300 and make the product structure more stable; when detaching the oral cleansing liquid capsule 300, the clamping end of the clamping assembly 400 is detached from the card slot 303, and the oral cleansing liquid capsule 300 is separated from the capsule accommodating cavity 103, which is convenient for the user to disassemble the oral cleansing liquid capsule 300 and the operation is convenient.

[0073] In this embodiment, the clamping assembly 400 includes a clamping member 410, a pressing member 420, and a second elastic member 430. The housing 100 is provided with a key hole 104. The pressing member 420 is disposed in the key hole 104. The first end of the second elastic member 430 abuts against the pressing member 420, and the second end of the second elastic member 430 abuts against the clamping member 410. The elasticity of the second elastic member 430 drives the clamping member 410 to be inserted into the clamping groove 303, and the pressing member 420 is used to drive the clamping member 410 to be detached from the clamping groove 303 under an external force. Through the setting of the above structure, when in use, the pressing member 420 is pressed, the second elastic member 430 deforms, the pressing member 420 drives the clamping member 410 to move outwards, and the clamping end of the clamping member 410 is detached from the clamping groove 303, so that the oral cleaning liquid capsule 300 can be conveniently separated from the capsule accommodating cavity 103; when the user releases the pressing member 420, the second elastic member 430 resets, drives the clamping member 410 to move inwards, and the clamping end of the clamping member 410 is clamped in the clamping groove 303, then the oral cleaning liquid capsule 300 can be stably connected to the capsule accommodating cavity 103, improving the stability of the product and being convenient for disassembly and assembly.

[0074] In this embodiment, the clamping assembly 400 further includes a transmission member 440. The first end of the transmission member 440 is rotatably connected to the pressing member 420, the middle part of the transmission member 440 is rotatably connected to the housing 100, and the second end of the transmission member 440 is rotatably connected to the clamping member 410. Through the setting of the above structure, when in use, the pressing member 420 is pressed, the second elastic member 430 deforms, the pressing member 420 pushes the transmission member 440 inwards to rotate around the middle part thereof, and the second end of the transmission member 440 drives the clamping member 410 to move outwards, so that the clamping end of the clamping member 410 is detached from the clamping groove 303; when the user releases the pressing member 420, the second elastic member 430 resets, drives the clamping member 410 to move inwards, and at the same time the clamping member 410 drives the transmission member 440 to rotate around the middle part thereof, and the transmission member 440 pushes the pressing member 420 outwards to make the pressing member 420 reset to the initial position.

[0075] In this embodiment, there are two clamping assemblies 400, and the two clamping assemblies 400 are disposed in the housing 100 and are respectively located on both sides of the capsule accommodating cavity 103. Through the setting of the above structure, the two symmetrically arranged clamping assemblies 400 can respectively be clamped to the clamping grooves 303 on both sides of the oral cleaning liquid capsule 300, which can not only enhance the stability of the product structure, but also prevent the user from accidentally touching. The user needs to press the pressing members 420 of the two clamping assemblies 400 simultaneously to separate the oral cleaning liquid capsule 300 from the capsule accommodating cavity 103.

[0076] In this embodiment, it further includes a pumping assembly 200. A water storage cavity 101 and a liquid outlet 102 communicating with the water storage cavity 101 are provided in the housing 100. The liquid outlet 102 is arranged at the bottom of the water storage cavity 101. The pumping assembly 200 is arranged in the housing 100. The liquid suction port 201 of the pumping assembly 200 extends to be arranged near the liquid outlet 102 at the bottom of the water storage cavity 101. The pumping assembly 200 is used to suck liquid and spray the liquid along the nozzle 210. An oral cleaning liquid containing cavity 301 is provided in the oral cleaning liquid capsule 300. The oral cleaning liquid capsule 300 is arranged at the bottom of the housing 100. The oral cleaning liquid containing cavity 301 communicates with the liquid outlet 102. The oral cleaning liquid capsule 300 is used to drive the oral cleaning liquid in the oral cleaning liquid containing cavity 301 to pass through the liquid outlet 102 and enter the water storage cavity 101 under the action of an external force. The axis where the force application direction of the oral cleaning liquid capsule 300 is located intersects or projects and intersects with the axis of the housing 100 in the vertical direction. Through the setting of the above structure, during use, the user holds the housing 100 and can simultaneously press the oral cleaning liquid capsule 300 at the bottom of the housing 100. The oral cleaning liquid capsule 300 is stressed, and the oral cleaning liquid therein is injected to the bottom of the water storage cavity 101. The pumping assembly 200 works. The liquid suction port 201 of the pumping assembly 200 extends to the bottom of the water storage cavity 101, and can suck the liquid with a higher concentration of oral cleaning liquid at the bottom of the water storage cavity 101, and the cleaning effect of the product is better. In order to ensure the stability of the center of gravity of the dental irrigator product, it is usually set with a narrower upper part and a wider lower part. The oral cleaning liquid capsule 300 is arranged at the bottom of the housing 100. The bottom of the housing 100 generally refers to the part below the midline of the housing 100 in the vertical direction, which allows a larger volume of the oral cleaning liquid capsule 300, thereby prolonging the service time of the product and reducing the frequency of replacing the oral cleaning liquid capsule 300, which is convenient to use. And because the axis where the force application direction of the oral cleaning liquid capsule 300 is located intersects or projects and intersects with the axis of the housing 100 in the vertical direction, there is no need to provide a greater holding force when pressing the oral cleaning liquid capsule 300. The user is more labor-saving and convenient when pressing the oral cleaning liquid capsule 300. The user can hold the product with one hand and press the oral cleaning liquid capsule 300 with the palm of the hand.

[0077] In this embodiment, the oral cleaning liquid capsule 300 includes a capsule housing assembly 310, a piston assembly 330, and a connecting housing 340. An oral cleaning liquid accommodation cavity 301 is provided in the capsule housing assembly 310. The capsule housing assembly 310 further has a piston cavity 311. The piston cavity 311 communicates with the oral cleaning liquid accommodation cavity 301 and is used to communicate with the liquid outlet 102 of the dental irrigator. The piston assembly 330 is slidably disposed in the piston cavity 311. The connecting housing 340 has a sliding cavity 341, and the capsule housing assembly 310 is slidably disposed in the sliding cavity 341. When the capsule housing assembly 310 slides inward along the sliding cavity 341 under an external force, the piston assembly 330 slides into the piston cavity 311 to eject the oral cleaning liquid in the piston cavity 311 along the liquid outlet 102 of the dental irrigator. It further includes a movable member 320. The movable member 320 is movably disposed in the capsule housing assembly 310. An oral cleaning liquid accommodation cavity 301 is formed between the inner wall of the movable member 320 and the inner wall of the capsule housing assembly 310. The movable member 320 moves in the direction towards the piston assembly 330 under the action of atmospheric pressure and the hydraulic pressure difference in the oral cleaning liquid accommodation cavity 301. Through the above structural arrangement, during use, when the capsule housing assembly 310 is pressed, the capsule housing assembly 310 and the movable member 320 move into the sliding cavity 341 along the direction of the force. At this time, the piston assembly 330 slides into the piston cavity 311, the pressure in the oral cleaning liquid accommodation cavity 301 increases, and the oral cleaning liquid flows from the oral cleaning liquid accommodation cavity 301 into the piston cavity 311, and then flows into the water storage cavity 101 along the liquid outlet 102, and the operation is simple. When the capsule housing assembly 310 resets, the piston assembly 330 slides in the direction away from the piston cavity 311, the pressure in the oral cleaning liquid accommodation cavity 301 becomes smaller, and the atmospheric pressure drives the movable member 320 to move inward along the axis direction of the oral cleaning liquid capsule 300 to maintain the pressure stability in the oral cleaning liquid accommodation cavity 301.

[0078] In this embodiment, the oral cleaning liquid capsule 300 further includes a first elastic member 350. The first end of the first elastic member 350 abuts against the capsule housing assembly 310, and the second end of the first elastic member 350 abuts against the inner wall of the sliding cavity 341. With the above structure, during use, when the capsule housing assembly 310 is pressed, the capsule housing assembly 310 slides in the sliding cavity 341 of the connecting housing 340, so that the piston assembly 330 slides towards the piston cavity 311. At this time, the first elastic member 350 is deformed by the force, and the oral cleaning liquid in the oral cleaning liquid containing cavity 301 flows out; when the user releases the capsule housing assembly 310, the first elastic member 350 resets and drives the capsule housing assembly 310 back to the initial position. Under the action of atmospheric pressure, the movable member 320 moves inward along the axis of the oral cleaning liquid capsule 300; the sliding cavity 341 of the connecting housing 340 can make the capsule housing assembly 310 move reciprocally more smoothly, and the user operation is more labor-saving and convenient. Moreover, using the connecting housing 340 can better connect the oral cleaning liquid capsule 300 with the housing 100 and protect each component therein; and the first elastic member 350 can realize the reset of the capsule housing assembly 310, and the operation is more simple.

[0079] In this embodiment, the connecting housing 340 is provided with a connecting channel 342. The first end of the connecting channel 342 communicates with the piston cavity 311, and the second end of the connecting channel 342 communicates with the liquid outlet 102. With the above structure, during use, when the capsule housing assembly 310 is pressed, the piston assembly 330 slides towards the piston cavity 311, the pressure in the oral cleaning liquid containing cavity 301 increases, the oral cleaning liquid flows from the oral cleaning liquid containing cavity 301 into the piston cavity 311, passes through the connecting channel 342, and then flows into the water storage cavity 101 along the liquid outlet 102.
