Description

Technical Field

[0001] The invention relates to an external faucet of a closed container. Background Art

[0002] People use a certain amount of liquid foods such as water, oil, and wine every day in their family life. Due to the large demand, it is impossible to use small bottles like vinegar and soy sauce, but they must be packaged in large bottles or even barrels. At present, the large bottles or barrels available on the market all use bottle caps or barrel covers, but the bottle caps or barrel covers have a particularly great impact on the preservation of liquids (such as water) contained in the large bottles or barrels during long-term and repeated use, which is specifically manifested in the following aspects: First, when pouring the liquid (such as water) in the barrel out of the large barrel, it can only be obtained by turning the barrel (bottle) upside down or scooping it out with a spoon, which causes unsmooth outflow and is extremely inconvenient to use; second, the liquid (such as water) taken out by this method is very easy to be contaminated again, affecting the quality of food and even causing food safety hazards; third, the barrel (bottle) cover is taken off and put on again frequently and repeatedly, which is not conducive to the preservation of liquid food in the barrel and easily causes the food to deteriorate during the shelf life; fourth, the barrel (bottle) cover is often taken off and put on again, which is bound to make it difficult to re-seal and have poor sealing performance. Therefore, developing a new type of large bottle or barrel with good sealing effect and convenient and simple use is of great significance to ensuring food safety and maintaining people's health. To this end, there is an urgent need for a barreled sealed container that can ensure simple operation, smooth outflow, easy re-sealing, not prone to secondary contamination and obvious shelf life during repeated use. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an external faucet that can ensure that the barreled sealed container is easy to operate, flows smoothly, is easy to reseal, is not prone to secondary pollution and has a significant preservation effect during repeated use, in view of the defects of existing large barrels of liquid (such as water) in use, outflow, resealing, secondary pollution and preservation effect during long-term and repeated use.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an external faucet, including a faucet box and an inserted pipe, wherein a drainage pipe, an exhaust pipe, a piston pipe and a piston hidden pipe are arranged inside the faucet box, a drainage pipe water inlet and an exhaust pipe exhaust port are arranged on the outer side of the faucet box, a faucet mouth is arranged on the outer bottom surface of the faucet box, and the faucet mouth is composed of an exhaust pipe air inlet and a drainage pipe water outlet, a manual switch box is arranged on the outer top of the faucet box, and a telescopic spring, a piston top, a return spring and a manual handle are arranged inside the manual switch box, and one end of the manual handle is connected to the top plate of the manual switch box. The manual handle is located above the piston top, the telescopic spring is located between the piston top and the bottom plate of the manual switch box, the return spring is located on the fulcrum connecting the manual handle and the manual switch box, the interior of the piston pipe is provided with an upper piston, a lower piston and a piston connecting rod, and the piston connecting rod connects the upper piston, the lower piston, the telescopic spring and the piston top into a whole; a breaking blade is provided at the front end of the insertion pipe, a water outlet is provided on the pipe wall at the middle end of the insertion pipe, the interior of the rear end of the insertion pipe is communicated with the water inlet of the drainage pipe and the exhaust port of the exhaust pipe, and the exterior of the rear end of the insertion pipe is sealed and connected to the outer side of the faucet box.

[0005] Furthermore, the drainage pipe, the exhaust pipe and the piston pipe inside the faucet box are an integrated structure that is interconnected, independent of each other and yet affects each other.

[0006] Furthermore, the manual handle, the telescopic spring, the piston top and the return spring form a whole that moves in a unified and coordinated manner.

[0007] Furthermore, the manual handle enables the upper piston and the lower piston to move up and down in conjunction in the piston pipe through the piston top and the piston connecting rod.

[0008] Furthermore, the manual switch box, the upper piston, the lower piston, and the piston connecting rod form an independent system that can be freely assembled or disassembled to facilitate the repair and maintenance of the external faucet.

[0009] Furthermore, the notching blade is a conical notching blade.

[0010] Furthermore, a leakage-blocking ring surrounding the rear end of the insertion pipe is provided at the sealing connection between the outside of the rear end of the insertion pipe and the outer side of the faucet box.

[0011] Furthermore, the faucet box and the inserted pipe are made of materials such as copper, stainless steel or polypropylene.

[0012] Technical principle of the present invention:

[0013] (1) By using a manually controlled manual handle to enable the upper piston and the lower piston in the manual piston to move up and down simultaneously in the piston pipe, the flow of water in the drainage pipe and the flow of air in the exhaust pipe are controlled, and the flow of water and the flow of air are coordinated to solve the problem of the external (water) faucet continuing to maintain a closed state in the container during the switch closing process.

[0014] (2) The conical breaking blade at the front end of the inserted pipe can be used to quickly break the sealed opening of the closed container, thereby solving the problem of the inserted pipe of the external (water) faucet smoothly entering the closed container from the outside along the preset (external) channel.

[0015] (3) By using the exhaust pipe and its exhaust port to form a certain air contact surface inside the rear end of the inserted pipe, the liquid (such as water) in the closed container can obtain the support of the air on the contact surface to restore its own weight, thereby solving the problem that the liquid (such as water) in the closed container can flow out smoothly from the external (water) faucet.

[0016] (4) Furthermore, a sealing ring (leakage-proof ring) is added to solve the problem of leakage of liquid (such as water) at the contact point between the container and the external (water) faucet and at the adhesion point between the inserted pipe and the outer side of the faucet box.

[0017] The present invention adopts the innovative design concept of "double tubes (drainage pipe, exhaust pipe) and double plugs (upper piston, lower piston)", which effectively solves the defects of current large barrels of liquid (such as water) in operation, outflow, re-sealing, secondary pollution and shelf life during long-term and repeated use. It has a reasonable structural design, feasible technical solutions and a wide range of applications. It is of great significance for effectively extending the shelf life of edible liquids (such as water) and preventing food from spoiling. It has strong market targeting and great development potential. BRIEF DESCRIPTION OF THE DRAWINGS
