Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in figure 1, the foam pump with the suck-back effect comprises an outer cover 1, a gland 2, an outer cover 3, a large racket 4, a small racket 6, a friction cylinder 7, a spring 8, a friction seat 9, a ball valve 10, a suction pipe 11, a pull rod 12 and a friction net 13. The outer cover 1 is buckled on the top of the outer cover 3, and the outer cover 1 is used for protecting the gland 2 positioned in the outer cover 1 from being accidentally pressed before the foam pump is used for the first time, so that the gland 2 can be prevented from being accidentally pressed to squeeze out liquid before transportation and non-use.
Clap 4 greatly and be located the inner chamber of enclosing cover 3, the inner chamber of enclosing cover 3 includes inner chamber and lower inner chamber, and the upper end of clapping 4 greatly stretches into the last inner chamber of enclosing cover 3, and the lower extreme of clapping 4 greatly extends to the lower inner chamber of enclosing cover 3, and extend to down 4 terminal and the 7 upper end swing joint of rubbing that lie in enclosing cover 3 inner chamber down that clap 4 greatly, clap 4 terminal greatly and can slide from top to bottom in axial direction along the inside wall that rubs 7 upper ends of a section of thick bamboo. The top end of the friction cylinder 7 is fixedly connected with the outer cover 3, and the friction cylinder 7 can also be connected with the inner upper wall of the outer cover 3 through a gasket 5.
The middle part of the lower end of the big racket 4 is provided with a notch which is connected with the upper end of the thin racket 6, so that the big racket 4 is connected with the thin racket 6. The joint of the notch of the large racket 4 and the upper end of the fine racket 6 is provided with a bone position gap, so that the joint of the large racket 4 and the fine racket 6 is provided with the bone position gap.
The fine racket 6 is positioned in a large cavity formed by the large racket 4 and the friction cylinder 7, the pull rod 12 is arranged in the fine racket 6, the top end of the pull rod 12 is movably connected with the top end of the fine racket 6 in a sealing manner, so that the fine racket 6 and the pull rod 12 can slide relatively, and a gap is reserved between the top end of the pull rod 12 and a notch of the large racket 4. The end of the pull rod 12 extends into a long notch of the friction seat 9, the pull rod 12 is sleeved with a spring 8, the spring 8 is arranged along the axial direction of the pull rod 12, one end of the spring 8 far away from the large racket 4 is fixed on the friction seat 9, and the friction seat 9 is fixed at the lower end of the friction barrel 7 and is located in the large cavity.
A ball valve 10 is further arranged in the massage cylinder 7 below the massage seat 9, the massage cylinder 7 at the lower end of the ball valve 10 is communicated and connected with a suction pipe 11, and the upper end of the suction pipe 11 is fixed at the tail end of the massage cylinder 7. The ball valve 10 is a circular sphere and can be made of metal or nonmetal materials.
In practice, the foam pump is usually mounted on a container containing the liquid, for example on a bottle of a bath lotion bottle for daily use, and is abutted against the container by the outer cover 3 (for example by screwing a thread on the inner wall of the outer cover 3 onto the upper end of the container). When the utility model is used for the first time, pull down dustcoat 1 from enclosing cover 3, pull down dustcoat 1 after, press down gland 2, gland 2 drives big bat 4 downstream through interior knot line 21, and at this in-process, because enclosing cover 3 is withstood by the container and gland 2 can slide relative enclosing cover 3, consequently, enclosing cover 3 remains stationary. Big 4 drive of clapping of 4 thin claps 6 and move down, because be located the pull rod 12 top of clapping 6 and clap 4 greatly and be provided with an interval and pull rod 12 and rub the frictional force effect between the seat 9 inner wall, 4 move down before contacting with pull rod 12 clapping 4 greatly, clap 4 greatly and thin clap 6 and move down a distance before pull rod 12 for the passageway of thin clapping 6 and pull rod 12 top is opened. When the pressing is continued, the big racket 4 is contacted with the pull rod 12, and the big racket 4 drives the pull rod 12 and the thin racket 6 to move downwards together. Liquid in the cavity at the lower part of the friction cylinder 7 flows out to a channel which is opened between the top of the pull rod 12 and the fine racket 6 through a bone position gap between the large racket 4 and the fine racket 6, and is mixed with air in the cavity at the channel part of the friction cylinder 7, and the mixed gas-liquid mixture forms foam through the friction net 13 and is finally discharged through a discharge channel in the gland 2, so that the foam is extruded through pressing. Wherein, the air of the upper cavity of the friction cylinder 7 enters from the external air through the gap between the gland 2 and the outer cover 3, and then enters into the container through the small hole of the friction cylinder 7, so as to balance the pressure in the container.
When the pressing is stopped, for example, after the hand pressing the gland 2 is released, the top end of the pull rod 12 forms an inclined plane seal with the racket 6 under the action of the spring 8, a vacuum environment is formed (close to) in the cavity below the rubbing tube 7, because the pressure in the container is greater than the pressure in the cavity below the rubbing tube 7, the ball valve 10 slightly moves upwards to open, the liquid in the container enters the lower space of the rubbing tube 7 through the suction pipe 11 and the ball valve 10 to be stored, and the volume of the part of the space can be set according to the requirement, for example, to be 0.4 CC. Synchronously, after the pressing gland 2 is loosened, negative pressure is generated at the bottom of the big racket 4, so that foam at the outlet (mouth) of the gland 2 and external air enter the upper cavity of the friction cylinder 7 through gaps among the gland 2, the friction net 13 and the big racket 4 to balance the air pressure, the foam in the discharge channel inside the gland 2 is sucked back into the friction cylinder 7, and the foam sucking back is completed. When the gland 2 is pressed again, the foam sucked back into the friction cylinder 7 from the previous time passes through the bone gap between the fine racket 6 and the large racket 4 together with air and is discharged again. By repeating the pressing-releasing operation, the foam liquid can be continuously extruded until the liquid is completely consumed or the external force of the pressing operation disappears, and the foam at the outlet of the gland 2 can flow back again after the contact pressing (i.e. the hand of a person is released) after each pressing, so that the liquid suck back is completed.
The utility model discloses after pressing at every turn loosen the completion after, can be with the foam resorption of exit to the foam pump in, there is not liquid to remain to avoid condensing the oral area or drip and breed the bacterium, improved user experience degree.
The embodiment disclosed in this specification is only an example of the single-sided features of the present invention, and the protection scope of the present invention is not limited to this embodiment, and any other embodiments having equivalent functions all fall into the protection scope of the present invention. Various other changes and modifications may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such changes and modifications should fall within the scope of the present invention.
