Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

The utility model discloses a drive pump can carry out the bubble production to water before rivers blowout to only need adopt a pump body can, easily make and save the cost, fig. 1-3 show, in the utility model discloses in have a cylinder body 11 that has cavity 111, when using, outside drive assembly drives and pushes away stopper 12 along movable passage 115 to the mode motion of keeping away from cavity 111, can form the negative pressure in cavity 111 this moment, under the effect of check valve one 116, outlet 114 is in closed state, and the check valve two 117 and the check valve three 118 that are located air inlet 112 and water inlet 113 department can be opened, thereby inhale in cavity 111 with outside air and water, after air and water entered cavity 111, air and water roll and mix thereby produce bubble water;

it is noted that, as shown in fig. 3, the portion of the movable passage 115 that is left free from the chamber 111 forms a larger mixing space with the original chamber 111 due to the movement of the plunger 12 away from the chamber 111.

After the mixing is completed, the external driving component drives the pushing plug 12 to move towards the chamber 111 along the movable channel 115, that is, the pushing plug 12 extrudes water and gas in the chamber 111, so as to increase the pressure in the chamber 111, at this time, the second check valve 117 located at the air inlet 112 and the third check valve 118 located at the water inlet 113 are closed, and the first check valve 116 located at the water outlet 114 is opened, so as to discharge water with bubbles, and the operation process is cycled as shown in fig. 6 and 7.

It should be noted that the pushing stopper 12 of the present invention has a sealing design, so that no air leakage or water leakage occurs in the active channel 115, and the prior art means can be used to perform the waterproof treatment, such as providing a waterproof sealing ring on the periphery of the pushing stopper 12, or adopting the design of the syringe piston head, so there is no unclear condition,

the utility model discloses a driving pump adopts the negative pressure principle to inhale gas and liquid from the entry of difference respectively, lies in cavity 111 again and mixes, has greatly practiced thrift the cost of adopting the double pump design, in addition, the utility model provides a water inlet 113, air inlet 112 adopt the check valve of equidirectional, outlet 114 adopts the check valve opposite to it, when producing the negative pressure, can avoid the water backward flow of outlet 114 department, can also avoid in the impurity follow outlet 114 suction cylinder body 11 in with the oral cavity when suck-back, when the drainage, also can avoid the water after the gassing to leak from water inlet 113 and air inlet 112, has guaranteed the independence of three function, can not mutual interference, improves work efficiency.

In this embodiment, referring to fig. 3 to 5, the first protrusion 121 is formed at the upper end of the push plug 12 along the outer periphery, when the push plug is connected, the first protrusion 121 abuts against the inner wall 119 of the movable passage, so that a sealing effect can be achieved, and other positions of the outer periphery of the push plug 12 do not contact with the inner wall 119 of the movable passage, so that the friction force of the push plug 12 during the movement can be reduced, and then, the second protrusion 122 is formed at the lower end of the push plug 12 along the outer periphery, when the push plug is connected, the second protrusion 122 abuts against the inner wall 119 of the movable passage, and by using the first protrusion 121 and the second protrusion 122 in cooperation, the push plug 12 is more stable during the movement, except that the first protrusion 121 and the second protrusion 122 contact with the inner wall 119 of the movable passage, there is a gap between other positions of the outer periphery of the push plug 12 and the inner wall 119 of the movable passage, so that the friction force of the push plug 12 during the movement can be reduced.

In the present embodiment, after the negative pressure is formed in the chamber 111, the external air and the external water are sucked into the chamber 111, and the water is tumbled after being flushed down the groove 123 by providing the groove 123 on the upper surface of the push plug 12, thereby generating more bubbles.

In this embodiment, referring to fig. 1 and 5, the driving assembly is a piston-type driving structure, the driving motor 136 drives the second gear 135 to rotate, the second gear 135 drives the first gear 133 to rotate synchronously, the eccentric transmission portion 134 is disposed on the first gear 133, and when the first gear 133 rotates, the eccentric transmission portion 134 also performs a circular motion with a center of the first gear 133 as a middle point, so as to drive the piston rod 132 to move up and down, that is, drive the piston 131 to drive the push plug 12 to move along the movable channel 115.

The utility model discloses still provide a tooth washing device including above-mentioned driving pump, refer to fig. 1-7, because wash tooth washing device with the embodiment of the driving pump of the utility model is based on same design, the technological effect that it brought is the same, and concrete content can refer to the utility model discloses narration in the driving pump embodiment, here is no longer described any more.

It should be noted that the action of the driving pump is very fast, and the time required for the processes of suction and discharge is very short, so that the water flow can be ejected at a high speed, in this embodiment, the check valve one 116 is a duckbill check valve, and firstly the duckbill check valve has a simple structure, and secondly, the outlet is closed when negative pressure is generated, and back suction is not generated, so that the basic function is ensured, and when the duckbill check valve is in a drainage state, the caliber of the duckbill check valve is small, so that the flow rate of water ejection can be increased.

In a further embodiment of the tooth flushing device, a first joint 2 is installed at a position corresponding to the air inlet 112 of the driving pump, the first joint 2 is connected with the air pipe, a second joint 3 is installed at a position corresponding to the water inlet 113 of the driving pump, the second joint 3 is connected with the water pipe, and the filter screen 4 is installed at a position located at the air inlet 112.

To another kind of embodiment towards tooth ware, the utility model provides a tooth ware not only can carry out the aqueous vapor and mix, can also carry out the mixture of two kinds of liquid, and air inlet 112 department that corresponds the driving pump installs joint one 2, joint one 2 is connected with the feed pipe that provides the washing liquid, and when producing the negative pressure in cavity 111, water and washing liquid are inhaled respectively in cavity 111, when two kinds of liquid collisions roll and mix, make the washing liquid foaming form the bubble, after the mixed liquid with the bubble is spout, can reach good clean effect equally.

The chamber 111 is not a complete vacuum, and air remains after each water discharge operation, so that the cleaning liquid can be foamed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
