Description

Technical Field

[0001] The invention relates to a solution filling device. Background Art

[0002] Existing solution filling devices typically squeeze the bottle upward to fill. When the bottle is released, air enters the bottle through a one-way valve, facilitating the next filling. This structure has the following disadvantages: It places high demands on the bottle's material, requiring it to withstand high hydraulic pressure and exhibit a high degree of deformation. Each filling requires squeezing the bottle, and the user must wait for the bottle to recover before squeezing again, resulting in low filling efficiency and cumbersome operation. Summary of the Invention

[0003] The object of the present invention is to provide a solution filling device which is simple to operate, has high filling efficiency and relatively low requirements on the material of the bottle.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A solution filling device comprises a container having an opening at an upper portion, a first cover connected to the opening, an air inlet and a liquid outlet provided on the first cover, an air inlet assembly communicating with the air inlet and located in the container, and a liquid outlet assembly communicating with the liquid outlet and located outside the container;

[0006] The air intake assembly includes an air intake pipe whose upper end is connected to the air inlet and a one-way valve connected to the lower end of the air intake pipe. The one-way valve extends downward into the container to a depth of h, and the height of the container is d, where h≥d / 2.

[0007] Preferably, the one-way valve includes a connecting seat whose upper end is sleeved on the lower end of the air inlet pipe, a first valve seat provided in the lower end of the connecting seat, and a valve core provided in the first valve seat.

[0008] Preferably, the opening is protruded on the container and has an external thread, and the first cover is sleeved on the opening and has a matching internal thread.

[0009] Preferably, the air inlet is a first tube body protruding below the first cover body, and the first tube body is sleeved on the upper end of the air inlet pipe.

[0010] Preferably, the liquid outlet is a second tube body protruding above the first cover body, and the liquid outlet assembly is sleeved on the second tube body.

[0011] More preferably, the liquid outlet assembly includes a flow guide tube with a lower end sleeved on the second tube body, and a switch valve provided at an upper end of the flow guide tube.

[0012] Further preferably, the switch valve includes a second valve seat whose lower end is connected to the upper end of the flow guide tube, and a second cover body that is liftably mounted on the second valve seat, and a liquid outlet is provided on the upper end side of the second valve seat, and the second cover body is lifted and lowered to cover or expose the liquid outlet.

[0013] Still further preferably, a first convex portion and a second convex portion are provided on the outer side of the second valve seat, the first convex portion and the second convex portion are arranged at intervals in the up and down directions, and the second cover body includes a second main body for sealing the liquid outlet, and a bayonet portion connected to the bottom of the second main body and located between the first convex portion and the second convex portion.

[0014] Preferably, the air inlet pipe is arranged in a vertical direction.

[0015] Preferably, the air intake pipe is arranged tilted in the up-down direction.

[0016] Due to the application of the above technical solution, the present invention has the following advantages over the prior art: The solution filling device of the present invention extends a one-way valve downwardly into the container through an air inlet pipe. This eliminates the need to squeeze the container during filling; the liquid flows out through the liquid outlet under the action of gravity by tilting the container. Because the container is tilted, the one-way valve remains above the liquid surface, and air entering the container through the one-way valve is not affected by the liquid pressure, allowing continuous liquid filling. This solution filling device is simple to operate, has high filling efficiency, and has relatively low requirements for the material of the bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1 As shown, this embodiment provides a solution filling device, including a container 1 with an opening 11 on the top, a first cover body 2 connected to the opening 11, an air inlet 21 and a liquid outlet 22 provided on the first cover body 2, an air inlet component 3 connected to the air inlet 21 and located in the container 1, and a liquid outlet component 4 connected to the liquid outlet 22 and located outside the container 1.

[0031] The air inlet assembly 3 comprises an air inlet pipe 31, the upper end of which communicates with the air inlet port 21, and a one-way valve 32 connected to the lower end of the air inlet pipe 31. The one-way valve 32 extends downward into the container 1 to a depth h, and the height of the container 1 is d, where h ≥ d / 2. In this embodiment, h = 3d / 4. With this arrangement, when the container 1 is tipped or tilted for filling, the one-way valve 32 approaches the liquid level and quickly rises above the liquid level during the filling process. Air entering the container 1 through the one-way valve 32 is not hindered by liquid pressure, allowing air to continuously enter the container 1, maintaining continuous and rapid liquid filling.

[0032] In this embodiment, the air inlet pipe 31 is arranged in a vertical direction. Through this arrangement, when the container 1 is inverted and filled, the one-way valve 32 can be higher than the liquid level quickly.

[0033] In another embodiment, the air inlet pipe 31 is arranged in an inclined direction in the vertical direction and extends downward to below the handle. Through this arrangement, when the container 1 is tilted by the handle to fill, the one-way valve 32 can also be raised above the liquid level quickly.

The lower end of the second valve seat 421 is inserted into the flow guide tube 41, and a liquid outlet hole 4211 is defined on the side of the upper end of the second valve seat 421. The second cover 422 is raised and lowered to cover or expose the liquid outlet hole 4211.

[0039] In this embodiment, a first protrusion 4212 and a second protrusion 4213 are provided on the outside of the second valve seat 421, and the first protrusion 4212 and the second protrusion 4213 are arranged at intervals in the up and down directions. The second cover body 422 includes a second main body 4221 for sealing the liquid outlet hole 4211, and a bayonet portion 4222 connected to the bottom of the second main body 4221 and located between the first protrusion 4212 and the second protrusion 4213.

[0040] Figure 2 In the embodiment, the second cover 422 is located at the top, and the bayonet portion 4222 abuts against the first protrusion 4212 above. At this time, the second body 4221 blocks the liquid outlet 4211.

[0041] Figure 3 In the embodiment, the second cover 422 is located at the bottom, and the bayonet portion 4222 abuts against the second protrusion 4213 below. At this time, the second body 4221 is located below the liquid outlet 4211, and the solution in the container 1 can be discharged outward from the liquid outlet 4211.

[0042] The working process of this embodiment is described in detail below:

[0043] When filling, press the second cover 422 downward to expose the liquid outlet 4211, then tilt or invert the container 1 so that the opening 11 faces downward, and output the liquid in the container 1 through the guide tube 41 and the switch valve 42. During the filling process, the one-way valve 32 is close to the liquid surface or above the liquid surface.
