Description

Technical Field

[0001] The present invention relates to the technical field of daily necessities, and particularly to a one-key ejection water suction nozzle. Background Art

[0002] Currently, most of the existing water bag water suction nozzles adopt a split-type water suction nozzle, that is, the suction nozzle and the cover body are separately arranged, and the cover body is detachably arranged on the suction nozzle. When in use, one hand needs to hold the water bag, and the other hand needs to hold the cover body and pull out the cover body. After drinking water, two hands are required to operate to cover the cover body again. In the case of using the water bag with one hand, such as when climbing a mountain with a hiking pole, the above-mentioned split-type suction nozzle cannot achieve one-handed operation for the user to drink water. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an ejection water suction nozzle that can achieve one-handed operation.

[0004] To achieve the above purpose, the solution of the present invention is as follows:

[0005] A one-key ejection water suction nozzle, including a housing, a left cover body, a right cover body, a connecting shaft, a rotating nozzle and a base. The base is arranged in the housing. The connecting shaft is arranged on one side of the housing or the base. The left cover body and the right cover body are both rotatably arranged on the connecting shaft with the connecting shaft as the rotation axis. The left cover body and the right cover body cooperate with each other, and further include a first torsion spring for closing the left cover body and the right cover body. The first torsion spring is sleeved on the connecting shaft. One torsion bar of the first torsion spring abuts against the left cover body, and the other torsion bar of the first torsion spring abuts against the right cover body. The closed left cover body and right cover body enclose a receiving cavity;

[0006] The base is provided with a first channel, and the rotating nozzle is provided with a second channel. One end of the rotating nozzle is rotatably arranged on the base, and the other end of the rotating nozzle is a free end. The rotation axis of the rotating nozzle is perpendicular to the connecting shaft. Further include a second torsion spring for controlling the rotation of the rotating nozzle. The second torsion spring is fixed on the base. One torsion bar of the second torsion spring abuts against the rotating nozzle. The rotating nozzle is arranged in a manner of approaching or departing from the receiving cavity. When the free end of the rotating nozzle is outside the receiving cavity, the first channel and the second channel are communicated. When the free end of the rotating nozzle is in the receiving cavity, the second torsion spring is in a compressed state, and the second channel and the first channel are not communicated with each other;

[0007] The maximum torsion of the second torsion spring is less than the maximum torsion of the first torsion spring;

[0008] It further includes a key column for prying open the left cover body and the right cover body in the closed state. The key column includes a key and a column body connected together, and the key column is movably arranged on the base.

[0009] Furthermore, both the left cover body and the right cover body each have a lower baffle, two fixing rings, and a cover body main body. The cover body main body is connected to the lower baffle, the fixing rings are arranged on the corresponding lower baffle, the connecting shaft passes through the fixing rings, a first inclined surface is formed on the cover body main body of the left cover body, a second inclined surface is formed on the cover body main body of the right cover body. When the left cover body and the right cover body are closed, the first inclined surface and the second inclined surface enclose a V-shaped notch, the V-shaped notch faces the housing, the end of the column body away from the key is a fitting portion that cooperates with the above V-shaped notch, and the width of the fitting portion is greater than the maximum width of the V-shaped notch.

[0010] Furthermore, the base includes a seat body and a mounting portion connected together. The seat body and the mounting portion are perpendicular to each other. One end of the first channel is located at the bottom of the seat body, the second end of the first channel is located on the side wall of the mounting portion. An axial hole is also formed in the rotating nozzle, the mounting portion passes through the axial hole, the water inlet end of the second channel is located on the inner side wall of the axial hole, the water outlet end of the second channel is located at the free end of the rotating nozzle. When the free end of the rotating nozzle is outside the accommodating cavity and the rotating nozzle rotates to the limit position under the action of the second torsion spring, the second end of the first channel and the water inlet end of the second channel coincide.

[0011] Furthermore, an O-ring is arranged at the mouth of the first channel, and the O-ring is arranged close to the second end.

[0012] Furthermore, a block is arranged on the base, and a slot cooperating with the block is arranged on the rotating nozzle.

[0013] Furthermore, the rotating nozzle includes a rotating tube, a soft rubber water suction nozzle, and a plug. The soft rubber water suction nozzle is sleeved on the rotating tube, the rotating tube has an accommodating cavity, and the plug is arranged in the accommodating cavity.

[0014] After adopting the above structure, the one-key ejection water suction nozzle of the present invention has the following beneficial effects: The left cover body and the right cover body are closed under the action of the first torsion spring. The second torsion spring controls the rotation of the rotating nozzle. When the rotating nozzle is located in the accommodating cavity surrounded by the left cover body and the right cover body, the second torsion spring is in a compressed state. Since the torsion force of the second torsion spring is less than that of the first torsion spring, the closing force of the left cover body and the right cover body is greater than the rotational force applied to the rotating nozzle at this time, and the rotating nozzle cannot push open the closed left cover body and right cover body. Therefore, when no external force is applied, the rotating nozzle remains in the state of being located in the accommodating cavity surrounded by the left cover body and the right cover body. When in use, only need to press the button column with one hand, the button column pushes open the left cover body and the right cover body, and the second torsion spring drives the rotating nozzle to make the rotating nozzle leave the accommodating cavity surrounded by the left cover body and the right cover body from the gap between the top-open left cover body and the right cover body. The rotating nozzle leaves the accommodating cavity surrounded by the left cover body and the right cover body and resets under the action of the second torsion spring. After resetting, the first channel and the second channel are communicated, and water can be absorbed at this time. After use, only need to operate with one hand and turn the rotating nozzle towards the above-mentioned accommodating cavity with the thumb and overcome the resistance of the first torsion spring to push open the left cover body and the right cover body. When the free end of the rotating nozzle is located in the above-mentioned accommodating cavity, the left cover body and the right cover body are closed under the action of the first torsion spring, and the storage of the rotating nozzle is completed. The whole process can be realized only by using one hand. BRIEF DESCRIPTION OF THE DRAWINGS
