Above-described piston stage clip bolt has the groove driving it to rotate for screwdriver, can be in-line fluting, cross recess, interior hexagonal flower shape groove or interior hex slot.
Above-described plug tube stage clip bolt has the groove driving it to rotate for screwdriver, can be in-line fluting, cross recess, interior hexagonal flower shape groove or interior hex slot.
Above-described piston is provided with the sealing ring for sealing, can be O type circle (with reference to GB/T3452.1-2005), can be Y shape rubber seal, rubber bud ring, V-arrangement combined seal ring (with reference to GB/T 10708.1-2000), can be cydariform circle, chevron circle (with reference to GB/T 10708.1-2000), also can be VD type rubber seal (with reference to JB/T 6994-1993), separate the air inside epicoele and cavity of resorption closely.
Above-described toothwash assembly comprises water supply connector, also comprise holding rod, cock and toothwash head, holding rod is middle porose tubular member, can supply water and pass through in hole, one end connects water supply connector, the other end is by thread connection toothwash head, holding rod there is transverse holes, cock is installed above, cock there is faucet hole, cock is separated into two parts the hole in the middle of holding rod, when cock rotates to certain angle position, faucet hole can be communicated with on holding rod by the two-part bore separated, cock is half-twist again, then faucet hole is not be communicated with on holding rod by the two-part bore separated, but block it.The centrage of faucet hole and the centrage complete matching in holding rod hole can be made, can make like this water in hole by time have maximum stream flow, can the centrage of faucet hole and the centrage in holding rod hole not complete matching yet, but have a certain degree, although water can pass through from hole, but being not maximum stream flow, is certain numerical value be between zero-sum peak flow values.
Above-described toothwash head is a bending tubular body, and middle hole can water flowing, and one end is threaded, and is connected by screw thread and holding rod; Polygon side's platform is had, so that use spanner to drive it to screw screw thread close to screw thread place; The other end is used for putting toothwash in human mouth.
Above-described toothwash head can make multiple spare part in advance, in order to keep health, avoid the cross infection of pathogenic bacteria, everyone fixing one of them toothwash head of use of kinsfolk, toothwash head is backed out from connection screw thread, and it can be just this kinsfolk's toothwash that the toothwash head changing another kinsfolk into is screwed on again.
For the ease of placing toothwash assembly, avoiding arbitrarily leaving about, avoiding toothwash head contact with desktop and be sticky with upper dirt, this utility model is provided with support, comprises half cylindrical shell, pole and base, and half cylindrical shell and pole connect, pole and base connect, and are placed on table top by base.Holding rod has bulge loop, and the external cylindrical surface of holding rod and the inner cylinder face of half cylindrical shell coordinate, and bulge loop is close to half body end surface, add action of gravity, toothwash assembly can stably be placed on support, and toothwash head is lifted aloft, discord deck contact, can not be sticky with the dirt on table top.
Need in use to be filled with appropriate air in tank body, make the water in tank body have suitable pressure, so tank body needs to maintain the space holding air, tank body is provided with waterline, must not exceed this waterline to the water surface during dress water of the inside, upper space can hold the air of high pressure.
Using method is as follows:
1. rotary-piston cylinder, makes piston cylinder separate from connecting screw thread with tank body.
2. in tank body, pour water into, the water surface must not exceed waterline.
3. screw the screw thread between piston cylinder and tank body, and screw, make thread seal tight.
4. guarantee that cock is in cut-off state, push and pull bar repeatedly.When firmly pushing away downwards, the air pressure of cavity of resorption is larger, the air pressure of epicoele and the pressure of tank inner chamber smaller, the air of cavity of resorption enters tank body intracavity by the check valve on piston cylinder, check valve on piston is closed automatically, and simultaneously extraneous air enters epicoele by the gap between connecting cap and piston rod.When firmly toward pull-up, cavity of resorption inner air pressure is smaller, and the air pressure of epicoele and the pressure ratio of tank inner chamber are comparatively large, and the air of epicoele enters cavity of resorption by the check valve on piston, the closed check valve on piston cylinder.Repeatedly push and pull bar repeatedly, just delivers to tank body intracavity the air in the external world, and the pressure of the endoceliac air of tank and water becomes large.
5. take off toothwash assembly from support, cock of outwarding winding, have current to eject under pressure, just can carry out toothwash by hand-held holding rod, the food residual of aiming in teeth space is rinsed, and also can remove tartar, tartar, also can be used for rinsing gum massage.Can wash to oneself facing to mirror, also can two people wash mutually, centre also can rotate cock makes current temporarily stop, when injection dynamics diminishes also can more repeatedly push and pull bar fill a little air, also piston cylinder assembly of can outwarding winding when water is finished adds some water again, charges gas and continues to use.
6. being used to complete rear air of releasing the inside, placing in order to using next time.
The beneficial effects of the utility model are: low price, simple to operate, just can self-servicely use at home, hospital or dental clinic need not be run, save time.
