Description

Technical Field

[0001] The utility model relates to the technical field of siphons, in particular to a piston-type siphon. Background Art

[0002] The siphon principle is a fluid mechanics phenomenon that allows liquid to be sucked without the aid of a pump. The siphon principle uses the force of the height difference of the liquid level to fill an inverted U-shaped tubular structure (called a siphon) with liquid, and then place the high end of the opening in a container filled with liquid. The liquid in the container will continue to flow out through the siphon to a lower position. The essence of the siphon is that it is caused by the liquid pressure and the atmospheric pressure.

[0003] There are several types of traditional siphons on the market:

[0004] 1. The hand-kneaded air bag siphon relies on the rebound force of the air bag to suck up water, but due to the limitation of the rebound force of the air bag, the siphon height that can be achieved is not high.

[0005] 2. Shake to pump out water. There is a one-way valve at the front end of the water pipe. Water is pumped into the pipe by shaking it with your hand, thereby achieving siphon flow. However, due to the shaking speed and liquid pressure, the siphon height can not be high.

[0006] Based on this background, a siphon that can realize very deep containers was developed. Utility Model Content

[0007] The purpose of the utility model is to provide a piston type siphon to solve the above-mentioned shortcomings in the technology.

[0008] In order to achieve the above object, the utility model provides the following technical solution: a piston siphon, comprising:

[0009] A siphon tube, one end of which is fixedly provided with a hose connected to the interior thereof, and one end of which is fixedly provided with a water pipe one-way valve;

[0010] A connecting rod, wherein the connecting rod is arranged inside the siphon tube, one end of the connecting rod passes through the other end of the siphon tube and extends to the outside thereof, a piston assembly is arranged at the other end of the connecting rod, and the piston assembly comprises an upper limiting component of a sealing ring integrally connected with the other end of the connecting rod, a lower limiting component of a sealing ring is arranged on one side of the upper limiting component of the sealing ring, a connecting plate is fixedly provided between the upper limiting component of the sealing ring and the lower limiting component of the sealing ring, a sealing ring is arranged between the upper limiting component of the sealing ring and the lower limiting component of the sealing ring, the sealing ring is arranged at the outer end of the connecting plate, the outer end of the sealing ring contacts with the inner wall of the siphon tube, and sealing ring exhaust holes are opened inside the connecting rod and the upper limiting component of the sealing ring.

[0012] Preferably, a water outlet pipe connected to the interior of the siphon is fixedly provided on the outer side of the other end of the siphon, so as to facilitate the discharge and transfer of water inside the water storage container.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figures 1 to 7 A piston siphon shown, comprising:

[0027] A siphon tube 2, one end of which is fixedly provided with a hose 3 connected to the inside thereof, and one end of which is fixedly provided with a water pipe check valve 4. A water pipe check valve 4 is added to one end of the hose 3 to prevent liquid from flowing back after entering the hose 3;

[0028] A connecting rod 5 is arranged inside the siphon tube 2, one end of the connecting rod 5 passes through the other end of the siphon tube 2 and extends to the outside thereof, a piston assembly is arranged at the other end of the connecting rod 5, and the piston assembly includes a sealing ring upper limiting component 6 integrally connected to the other end of the connecting rod 5, a sealing ring lower limiting component 7 is arranged on one side of the sealing ring upper limiting component 6, a connecting plate 8 is fixedly arranged between the sealing ring upper limiting component 6 and the sealing ring lower limiting component 7, a sealing ring 9 is arranged between the sealing ring upper limiting component 6 and the sealing ring lower limiting component 7, the sealing ring 9 is arranged at the outer end of the connecting plate 8, the outer end of the sealing ring 9 contacts the inner wall of the siphon tube 2, and a sealing ring exhaust hole is opened inside the connecting rod 5 and the sealing ring upper limiting component 6 10. When the piston assembly is pulled, liquid enters the hose 3, but one pull is not enough to achieve high-depth siphon flow, and the piston assembly needs to be pulled repeatedly. For this reason, the sealing structure of the piston assembly is improved, and it is no longer "completely sealed". It can be achieved that when the piston assembly is pulled, the sealing ring 9 is in a sealed state, allowing liquid to enter the hose 3. When the piston assembly is pushed, there is no sealing effect, and the air in the piston assembly can be discharged, while the liquid in the hose 3 does not change. In this way, by repeatedly pulling the piston assembly, more and more liquid will be in the hose 3. When the liquid level in the hose 3 is lower than the level of the pumped liquid, there is no need to pull the piston anymore. Pull the piston to the outermost side to achieve siphon flow.

[0029] A handle 11 is integrally connected to the outer side of one end of the connecting rod 5, and a water outlet pipe 12 connected to the inner side of the other end of the siphon tube 2 is fixedly provided on the outer side.

[0030] Put the water inlet end of the hose 3 into the external water storage container, pull the handle 11 outward, the handle 11 drives the connecting rod 5 to move outward, at this time, the sealing ring 9 is in close contact with the lower limiting part 7 of the sealing ring, and the piston assembly is in a sealed state. At this time, the liquid enters the hose 3 through the water pipe one-way valve 4. After the piston assembly is pulled to the end, the piston assembly is pushed inward. At this time, the sealing ring 9 is in close contact with the upper limiting part 6 of the sealing ring, and the edge of the lower limiting part 7 of the sealing ring is connected with the gaps between the multiple connecting plates 8 and the sealing ring exhaust hole 10. The air in the piston assembly is discharged from the sealing ring exhaust hole 10. At this time, due to the presence of the water pipe one-way valve 4, the liquid in the hose 3 will not return to the external water storage container. Repeat the above steps. At this time, the liquid in the hose 3 gradually increases. When the liquid level in the hose 3 outside the water storage container is lower than the liquid level of the water storage container, the piston assembly is pulled to the outermost side to make the water outlet pipe 1 lower than the liquid level in the water storage container. At this time, the siphon phenomenon conditions are met and the liquid can flow out automatically.

[0031] The utility model can realize siphon self-flow over a long distance without using electricity through the repeated movement of the piston assembly, and can also realize siphon self-flow in very deep containers, thereby realizing liquid transfer more conveniently. This implementation specifically solves the problem of low siphon height of siphon devices existing in the prior art.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
