[0043] As shown in the structural diagram of the piston 6, the piston 6 has a spherical top surface which is matched with and forms a sealing dynamic cooperation with the spherical inner cavity provided in the stator; the piston 6 also has two angled side surfaces; a protruding shoe 602 is provided in the center of the spherical top surface of the piston 6, and the shoe 602 has two parallel working surfaces.

[0045] The cylindrical hinge in the embodiment is a C-type cylindrical hinge connection, and the piston pin seat 601 is protruding semicylindrical structure on the lower part of the two side surfaces of the piston 6, and the two ends of the semicylindrical structure are spherical surfaces. The rotary disc pin seat 701 is a semicylindrical hole structure on the upper end surface of the rotary disc 7, and the axis of the semicylindrical hole of the rotary disc pin seat 701 is parallel to the two side surfaces parallel to the slider shoe 602. The rotary disc pin seat 701 is matched with the piston pin seat 601, the protruding semicylindrical structure of the piston pin seat 601 is inserted into the semicylindrical hole of the rotary disc pin seat 701 to form a C-type cylindrical hinge connection, and a sealing dynamic fit is formed between the matching surfaces of the C-type cylindrical hinge connection.

[0046] The rotary disc shaft 702 is connected with the motor 13, and in the specific work, the rotary disc shaft 702 is driven to rotate by the motor 13, the rotary disc shaft 702 drives the rotary disc 7, the piston 6 and the slider shoe rotating sleeve 8 to rotate synchronously, that is, the spherical rotor rotates in the spherical inner cavity. When the rotary disc shaft 702 drives the rotary disc 7 and the piston 6 to rotate, the slider shoe 602 reciprocates in the sliding groove 801, and the piston 6 and the rotary disc 7 swing relative to each other, thereby forming two working chambers 100 with alternating volumes between the upper end surface of the rotary disc 7 and the two side surfaces of the piston 6 and the spherical inner cavity.

[0047] When one of the working chambers 100 needs to suck liquid, the liquid inlet 501 provided on the cylinder cover 5 is connected, and at the same time, the gas inlet nozzle 9 is provided on the liquid inlet 501 of the spherical pump. After the spherical pump is started, liquid is sucked into the liquid inlet 501 through the negative pressure effect, the liquid enters the liquid inlet channel in the liquid inlet 501, enters the liquid inlet groove 504 through the liquid inlet groove 504, and enters the working chamber 100 through the liquid inlet groove 504. At the same time, under the action of negative pressure, external gas is sucked into the liquid inlet 501 through the gas flow channel 901 in the gas inlet nozzle 9, the gas enters the liquid inlet channel in the liquid inlet 501, enters the liquid inlet groove 504 through the liquid inlet groove 504, and enters the working chamber 100 through the liquid inlet groove 504. The gas and liquid are mixed in the working chamber 100 of the spherical pump, the gas is mixed into the liquid to form liquid with bubbles; when the other working chamber 100 needs to compress and discharge liquid, the liquid discharge groove 505 provided on the semispherical inner cavity II of the cylinder cover 5 is connected, and the liquid discharge groove 505 is connected with the liquid discharge channel provided in the liquid discharge port 502; the bubbles contain pressure after being compressed in the pump body, the bubbles and the liquid are mixed and sprayed onto the teeth through the nozzle after being pressurized by the pump, and the bubbles with pressure are instantaneously burst after contacting the teeth. The impact force generated after the bubbles are instantaneously burst can effectively remove the dental plaque bacteria and interdental residues on the teeth.

[0048] Wherein, the rotary disc shaft 702 rotates one round, the rotary disc 7 and the piston 6 also rotate one round, the slide shoe 602 swings one time in the slide groove 801 set on the lower end surface of the slide shoe rotating sleeve 8, two working chambers 100 each occurs one complete liquid suction and air suction and liquid discharge and air discharge process, the bubble and liquid mixture sucked through the liquid inlet 501 and liquid channel enters into the working chamber 100 through the liquid inlet groove 504, and the bubble and liquid mixture is discharged through the liquid discharge channel in the liquid discharge groove 14 and liquid discharge port 12 after being pressurized by the pump body.

[0049] The current gas-liquid mixed water dental floss generally directly sets the air inlet part on the nozzle, and drives the gas entering from the nozzle to be directly sprayed out while spraying water, but this way, the gas mixed in the liquid is less, and the number of bubbles formed is less; while the gas is sucked at the same time as the liquid is sucked in the gas-liquid mixed water dental floss provided in the embodiment, the gas and the liquid are fully mixed in the working chamber 100 and sprayed out through the nozzle after being pressurized by the pump, and a large number of dense bubbles with pressure sprayed out through the nozzle will be instantaneously burst after contacting the tooth surface or the blind area of the tooth, the impact force generated by the bubble burst can wash away the dirt on the tooth surface and the residual food residues between the teeth, and the dense bubbles and the liquid formed together contacting the tooth surface can make the impact process more gentle, so that the user will not feel pain due to the excessive impact force, and the user's use comfort can be improved.

[0050] Embodiment 2

[0051] The embodiment is based on embodiment 1, and the difference between the embodiment and embodiment 1 is that the air inlet 101 is set on the outer shell 1 in the embodiment, the air inlet 101 is communicated with the air inlet end of the airflow channel 901 through the communication pipe 10, and the air discharge direction of the air discharge end of the airflow channel 901 and the liquid inlet direction of the liquid inlet of the spherical pump are at a certain angle in the embodiment; as shown in Figure 10 , it is a schematic diagram of the gas-liquid mixed water dental floss provided in embodiment 2.

[0052] Preferably, the air discharge direction of the air discharge end of the airflow channel 901 is perpendicular to the liquid inlet direction of the liquid inlet channel in the liquid inlet of the spherical pump.

[0053] Preferably, the first connecting seat 11 and the second connecting seat 12 are respectively fixed at both ends of the communication pipe 10, as shown in Figure 11 , it is a schematic diagram of the connection of the communication pipe 10 and the first connecting seat 11 and the second connecting seat 12; the first connecting seat 11 is detachably connected with the air inlet nozzle 9, and the second connecting seat 12 is detachably connected with the outer shell, and the use of the first connecting seat 11 and the second connecting seat 12 can quickly detach and connect the communication pipe 10 with the air inlet nozzle 9 and the outer shell, so as to facilitate the replacement of the communication pipe 10.

[0055] In the embodiment, the air inlet 101 is formed on the outer shell 1, and the air inlet 101 is connected with the airflow channel 901 through the communication pipe 10; the communication pipe 10 has two advantages, first, because the external gas of the outer shell 1 is sufficient, more gas is sucked under the negative pressure after the spherical pump rotates; second, if liquid backflow occurs, the backflow liquid will enter the communication pipe 10 through the airflow channel 901, and because the communication pipe 10 has a certain length, the backflow liquid will not be directly sprayed out, but will be temporarily stored in the communication pipe 10 and then enter the working chamber 100 in the next liquid suction process; meanwhile, the exhaust direction of the exhaust end of the airflow channel 901 is perpendicular to the liquid inlet direction of the liquid inlet of the spherical pump in the embodiment, which can further avoid liquid backflow.

[0056] Specifically, the working process of the gas-liquid mixed water dental floss in the embodiment is the same as that in embodiment 1, and will not be repeated here.
