[0069] Referring to Figures 1 to 18 , a bottom shell of a dental irrigator, the bottom shell 120 is used to connect to the upper shell 110 of the dental irrigator to form the entire shell 100 and a water storage cavity 101 inside the shell 100. Among them, the bottom shell 120 is provided with a semi-cylindrical capsule accommodating cavity 103, and the capsule accommodating cavity 103 is used to allow the oral cleaning liquid capsule 300 of the dental irrigator to be inserted and used. The ratio of the length to the width of the capsule accommodating cavity 103 is about 1.5 - 2.0.

[0070] Through the setting of the above structure, since the dental irrigator is usually set with a narrow upper part and a wide lower part, and its lower diameter is larger, by setting the capsule accommodating cavity 103 in the bottom shell 120, a larger-sized capsule accommodating cavity 103 can be allowed, and a larger-volume oral cleaning liquid capsule 300 can be allowed to be used, thereby extending the usage time of the product, reducing the frequency of replacing the oral cleaning liquid capsule 300, and being convenient to use. Moreover, by setting the oral cleaning liquid capsule 300 in the bottom shell 120, when the user uses the dental irrigator, only need to use the palm to squeeze the oral cleaning liquid capsule 300 to realize the injection of the oral cleaning liquid, and the usage experience is good. Preferably, the ratio of the length to the width of the capsule accommodating cavity 103 is 1.8, which can not only accommodate a larger oral cleaning liquid capsule 300, but also enable the inside of the bottom shell 120 to have a moving space to accommodate other components, and the design is reasonable.

[0071] In this embodiment, it further includes a first sealing ring 130. The upper edge of the bottom shell 120 is provided with a first sealing groove 122. The first sealing ring 130 is inserted into the first sealing groove 122, and the outer surface of the first sealing ring 130 is used to abut against the inner wall of the upper shell 110. Through the setting of the above structure, during use, the bottom shell 120 is installed on the upper shell 110. At this time, the outer surface of the first sealing ring 130 abuts against the inner wall of the upper shell 110, and the inner surface and the upper and lower surfaces of the first sealing ring 130 are connected and abut against the inner wall of the first sealing groove 122, which can increase the sealing performance of the product, prevent the liquid in the water storage cavity 101 from leaking, and improve the sealing performance of the product.

[0072] In this embodiment, the bottom shell 120 is provided with a key hole 104, and the key hole 104 is used to allow the pressing member 420 in the clamping assembly 400 of the dental irrigator to penetrate and be used. The inner wall of the capsule accommodating cavity 103 is also provided with a through hole for the clamping member 410 in the clamping assembly 400 of the dental irrigator to pass through. Through the setting of the above structure, the installation health 104 can allow the pressing member 420 to penetrate, and the installation is convenient and stable.

[0073] In this embodiment, a water leakage groove 129 is provided on the bottom shell 120, and the water leakage groove 129 communicates with the internal space of the bottom shell 120. With the above structure, during use, the water leakage groove 129 can allow the accumulated water in the bottom shell 120 to flow out, ensuring the dryness inside the product and preventing the growth of bacteria. Preferably, the water leakage groove 129 is provided at the bottom of the bottom shell 120.

[0074] Referring to Figures 1 to 18 , a dental irrigator includes the bottom shell 120 and the upper shell 110 as described above. The bottom shell 120 is detachably connected to the upper shell 110 to form the entire shell 100, and a water storage cavity 101 is formed between the upper shell 110 and the bottom shell 120. With the above structure, the upper shell 110 and the bottom shell 120 are detachably arranged, allowing the user to detach the bottom shell 120, thereby opening the water storage cavity 101, facilitating the user to clean the water storage cavity 101, ensuring the cleanliness of the water storage cavity 101, and thus ensuring the oral safety of the user.

[0075] In this embodiment, it further includes a pumping assembly 200 and an oral cleaning liquid capsule 300. An outlet 102 communicating with the water storage cavity 101 is provided in the shell 100, and the outlet 102 is provided at the bottom of the water storage cavity 101. The pumping assembly 200 is arranged in the shell 100, and the liquid suction port 201 of the pumping assembly 200 extends to be near the outlet 102 at the bottom of the water storage cavity 101. The pumping assembly 200 is used to suck the liquid and spray the liquid along the nozzle 210. The oral cleaning liquid capsule 300 is provided with an oral cleaning liquid containing cavity 301. The oral cleaning liquid capsule 300 is arranged at the bottom of the shell 100, and the oral cleaning liquid containing cavity 301 communicates with the 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 outlet 102 and enter the water storage cavity 101 under the action of an external force. The axis in the direction of the force on the oral cleaning liquid capsule 300 intersects or projects and intersects with the axis in the vertical direction of the shell 100.

[0076] With 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 chamber 101. The pumping assembly 200 operates. The liquid suction port 201 of the pumping assembly 200 extends to the bottom of the water storage chamber 101, and can suck the liquid with a relatively high concentration of oral cleaning liquid at the bottom of the water storage chamber 101, resulting in a better cleaning effect of the product. In order to ensure the stability of the center of gravity, the oral irrigator product is usually designed with a narrower upper part and a wider lower part. By arranging the oral cleaning liquid capsule 300 at the bottom of the housing 100, which generally refers to the part of the housing 100 below the vertical midline, a larger volume of the oral cleaning liquid capsule 300 can be allowed, thereby extending the usage time of the product and reducing the frequency of replacing the oral cleaning liquid capsule 300, which is convenient to use. Moreover, since the axis of the stress direction of the oral cleaning liquid capsule 300 intersects or projects and intersects with the axis of the housing 100 in the vertical direction, no greater holding force needs to be provided 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.

[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 oral 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 toward the inside of the piston cavity 311 to spray the oral cleaning liquid in the piston cavity 311 out along the liquid outlet 102 of the oral 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 toward 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 toward the inside of the sliding cavity 341 along the force application direction. At this time, the piston assembly 330 slides toward the inside of 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 into the water storage cavity 101 along the liquid outlet 102, with simple operation. 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 keep the pressure in the oral cleaning liquid accommodation cavity 301 stable.

[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 force, and the oral cleaning liquid in the oral cleaning liquid accommodating 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 reciprocate more smoothly, making it more labor-saving and convenient for the user to operate. Moreover, using the connecting housing 340 can better connect the oral cleaning liquid capsule 300 to the housing 100 and protect each component therein. The first elastic member 350 can realize the reset of the capsule housing assembly 310, making the operation simpler.

[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 accommodating cavity 301 increases, the oral cleaning liquid flows from the oral cleaning liquid accommodating 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. The operation is simple, the flow channel of the oral cleaning liquid is unobstructed, and the product structure is stable.

[0080] In this embodiment, the piston assembly 330 includes a fixed rod 331 and a piston rod 332. The fixed rod 331 abuts against the housing 100 and is inserted into the piston chamber 311, and the piston rod 332 is slidably inserted into the piston chamber 311. With the above structure, during use, when the capsule housing assembly 310 is pressed, the capsule housing assembly 310 and the movable member 320 move along the direction of the force. At this time, the fixed rod 331 slides towards the inside of the piston chamber 311, and the piston rod 332 moves towards the fixed rod 331 along with the capsule housing assembly 310 until the piston rod 332 abuts against the fixed rod 331. At this time, the piston rod 332 continues to slide towards the inside of the piston chamber 311 along with the fixed rod 331, the pressure in the piston chamber 311 increases, and the oral cleaning liquid in the piston chamber 311 flows into the connection channel 342 under the pressure drive and then flows into the water storage chamber 101 along the liquid outlet 102; 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. The fixed rod 331 slides in the direction away from the piston chamber 311, the atmospheric pressure drives the movable member 320 to move inward along the axis of the oral cleaning liquid capsule 300, and the pressure in the oral cleaning liquid accommodating chamber 301 drives the oral cleaning liquid to flow into the piston chamber 311, and the piston rod 332 slides in the direction away from the piston chamber 311.
