Detailed Description

Referring to fig. 1-6, the present invention relates to a water-gas mixed tooth-rinsing device nozzle, including a hollow nozzle body 100, the top end of the nozzle body 100 is provided with an outlet 112, the bottom end of the nozzle body 100 is provided with a water inlet 132, the side wall surface of the nozzle body 100 near the bottom end is provided with an air inlet 123, the nozzle body 100 includes an integrally formed nozzle part 110, a nozzle tube 120 and a connector 130 connected to a tooth-rinsing device body (not shown), the outlet 112 is located on the end surface of the nozzle part 110, a partition plate 124 is provided in the nozzle tube 120, the partition plate 124 divides the inner space of the nozzle tube 120 into two parts to form a water flow passage 121 and an air flow passage 122 which are axially arranged in parallel and arranged along the length direction of the nozzle tube 120, the water inlet 132 is located on the end surface of the connector 130, the water inlet 1211 of the water flow passage 121 is connected to the water inlet 132, the transverse cross-sectional area of the water inlet 1211 is smaller than the cross-sectional area of the water inlet 132, the pressure of the rinsing liquid entering the water flow passage 121 is increased, the

ends

1221 and 123 of the air flow passage 122 are connected to the air flow passage 110, the water flow passage 121 is capable of storing more water, and the rinsing liquid is more effective, and the water flow is formed by the water flow mixing amount of the water flow passage 110, and the water flow 122, the water flow passage 111. The rinse liquid is pumped into the water inlet 132 by the water pump of the tooth flusher body and then flows in the water flow channel 121, the gas flows in the gas flow channel 122, and the rinse liquid and the gas are mixed in the water-gas mixing space 111 to form bubble rinse liquid which is sprayed out through the spray outlet 112.

The working principle is as follows: the rinse liquid is pumped into the water inlet 132 by the water pump of the tooth flusher body and then enters the flow guide tube 120, the flow guide tube 120 is divided into two parts by the partition plate 124 to form the water flow passage 121 and the air flow passage 122, because the inner wall of the flow guide tube 120 and the partition plate 124 form a conical surface, and the transverse area of the water flow passage 121 gradually decreases from the water inlet 1211 to the water outlet 1212, the flow rate of the rinse liquid becomes faster, the pressure of the water outlet 1212 becomes smaller, the rinse liquid rushes out the water outlet 1212 and continues to be sprayed out from the spray outlet 112 along the water-air mixing space 111, because the water-air mixing space 111 is very short, the rinse liquid is sprayed out from the spray outlet 112 rapidly, so that the water-air mixing space 111 forms a negative pressure, the gas of the air flow passage 122 communicated with the outside through the air inlet 123 is "sucked" into "gas due to the negative pressure, the" sucked "gas is cut into small bubbles under the shearing action and the pressure action of the rinse liquid continuously rushed out from the water-air mixing space 111, the washing liquid is mixed in the washing liquid to form stable bubble washing liquid, finally the bubble washing liquid is released from the spraying port 112, the washing liquid is only needed to be input into the water flow channel 121 through the water inlet 132, no additional power is needed, negative pressure can be automatically generated, gas can be automatically sucked in through the air inlet 123 through the gas flow channel 122, the operation is simple and convenient, the energy consumption is low, the dissolved bubbles are small in size, the gas solubility can be effectively improved, the guide pipe 120 is divided into two parts to realize the simultaneous supply of water and air, meanwhile, the space in the length direction of the guide pipe 120 is utilized to store more air, the washing liquid output from the water flow channel 121 is output along the length direction of the guide pipe 120 and is fully contacted with the air entering the water-gas mixing space 111, the quantity of the washing liquid in the washing liquid is increased, the more the gas quantity dissolved in the washing liquid is, and the effect of micro-bubble water is more obvious, the flushing effect is better. Because the air inlet 123 is located on the flow guide tube 120 and far away from the nozzle part 110 and close to the limit stop 140, the air inlet 123 cannot be placed in the inlet, so that the blockage of the air inlet 123 is avoided, and the air inlet efficiency is improved.

Further, a water inlet cavity 131 is arranged in the joint 130, a sealing plug 125 is arranged at the joint of the water inlet cavity 131 and the partition plate 124, the sealing plug 125 divides the water inlet cavity 131 into two parts and seals the bottom end of the air flow passage 122, the partition plate 124, the sealing plug 125 and the inner wall surface of the draft tube 120 enclose the air flow passage 122, the water inlet cavity 131 is communicated with the water inlet end 1211 of the water flow passage 121, flushing liquid firstly enters the water inlet cavity 131 and then flows in the water flow passage 121, and therefore the transverse sectional area of the water flow passage 121 is smaller than that of the water inlet cavity 131, and the water pressure entering the water flow passage 121 is increased.

Further, the outer wall of the joint 130 is provided with a groove 133 to facilitate connection with the tooth flusher body. A limit stop 140 is arranged between the joint 130 and the guide tube 120, and the nozzle body 100 can play a role in positioning when being mounted on the tooth flushing device body.

Further, the discharge port 112 is provided with a relief hole 113, the relief hole 113 is perpendicular to the cavity of the water-air mixing space 111, the relief hole 113 may be provided in one or more than one, and the provision of the relief hole 113 can avoid the possibility that a user blocks the discharge port 112 during use, thereby avoiding the possibility that the flushing fluid flows back from the water flow path 121 to the air flow path 122 due to the blocking of the discharge port 112.

The utility model discloses be applied to a towards tooth ware, including the mixed towards tooth ware shower nozzle of aqueous vapor and towards tooth ware fuselage, can make the flush fluid contain the bubble and the blowout contains the flush fluid of bubble through this shower nozzle.
