Description

Single-mouth wind nozzle and direct pressure double valve nozzle automatically switch the air nozzle

The invention relates to a wind mouth head which can be used alone or in combination. More specifically, it relates to the technical field of directly inflating by inserting a nozzle to be inflated by one hand, thereby greatly improving the technical field. The dual-use wind mouth is smooth and convenient when pumping.

Press, the previous two-use wind mouth is like China's application No. 095107665, No. 097203517. . As shown in the previous patent case, however, these patents have the following disadvantages:

1. In the case of these patents, when pumping, you must hold the body with one hand and control the nozzle to be inserted into any nozzle, and then use another hand to push the wrench to move the internal cylinder down. The mouthpiece of the movable mouth is to be inflated, and finally, the air can be pumped. This mode of operation through both hands is not convenient, and it is time-consuming and laborious.

Second, the patents are forced to move the nozzle axially through the downward movement of the cylinder to "indirectly" actuate the nozzle to be inflated by the radial deformation of the nozzle. The radial deformation of the nozzle is quite limited. Therefore, the force of the mouthpiece to be inflated is quite limited, so when inflating, it is very easy to have a gas leak problem.

Third, the overall structure of the patents is too complex, resulting in manufacturing and assembly costs that cannot be reduced.

In view of this, the inventor has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the inventor has finally obtained the practical invention.

That is, the main object of the present invention is to allow the tuyere to be pumped with only one hand.

The secondary object of the present invention is to allow the wind mouth head to have two types of nozzles, so that the wind mouth head can not only be operated by one hand, but also can be freely selected according to the type of the air nozzle to be used.

The present invention provides a direct-pressure double-nozzle automatic switching air nozzle head, which at least includes: a body having a valve hole penetrating therethrough, and an air supply hole is connected between the two ends of the valve hole; a first nozzle having a first nozzle hole for the first to-be-inflated nozzle; an annular second nozzle having a second nozzle for the second inflation nozzle to be inserted; and a valve a plug capable of moving between the first and second positions along the axial direction of the valve hole; the valve plug is provided with a plurality of first jaws and second jaws, so that the first jaws are The first layer is configured to define a first bundle of holes coaxial with the valve hole and radially convergent, the first beam is for coaxial insertion and assembly of the first nozzle, and the second clamp The claws are arranged in a ring shape to define a second beam hole coaxially disposed with the valve hole and radially converging, and the second beam hole is coaxially inserted into the second nozzle When the first to-be-inflated nozzle is engaged with the first nozzle, the valve plug can be moved to the first position, the valve hole releases the second jaw, and the first jaw is pressed, so that the first beam is automatically Radially clamping the first nozzle, and the air supply hole is opened to the first nozzle hole, so that the first to-be-inflated nozzle can be pumped; however, when the second to-be-inflated nozzle is inserted into the second nozzle, the second nozzle is used for interlocking When the valve plug is moved to the second position, the valve hole releases the first jaw and presses the second jaw, so that the second jaw automatically clamps the second nozzle automatically, and the air supply hole is turned on the second The mouth hole, the cockroach can pump the second to-be-inflated nozzle.

The present invention further provides a single-nozzle tuyeres comprising: a body having a valve bore therethrough, and an air supply opening between the two ends of the valve bore; an annular first nozzle, The utility model has a first nozzle hole for inserting a gas inlet nozzle, the first nozzle is disposed in a valve plug, and a valve plug is disposed in the body, which is axially movable along the valve hole of the body. Restricting reciprocating movement between the first position and the second position; one end of the valve plug is provided with a plurality of jaws, and the other end forms a closed pressing portion, and the valve plug is internally formed with a flow path Conductively connected to the outer annular surface, the jaws are arranged in a ring shape by a groove, for defining a beam hole coaxially arranged with the valve hole and radially converging, the outer surface of each jaw Forming a radially enlarged bow portion, the beam hole is for coaxial insertion and assembly of the first nozzle; when the first nozzle to be inflated is inserted into the first nozzle, it can move the valve plug to the first position, so as to press The protrusion protrudes to the outside of the valve hole, and at the same time, the valve hole presses each of the clamping jaws, and the guiding of the arc of each of the clamping jaws causes the beam aperture to Radially clamping the first mouthpiece and the hole for the valve plug are simultaneously turned on to the inner surface of the outer ring and the first nozzle hole ilk channel to be able to pump to a pneumatic nozzle.

Therefore, the present invention has at least the following advancement:

1. The present invention can be easily operated by simply manipulating the body through one hand when providing air pumping. This one-hand operation mode is far more convenient and simpler than the conventional two-hand operation, and has the benefit of saving time and labor. Nothing wrong.

2. The jaw of the present invention is a "direct" compression nozzle that is radially deformed to strongly restrain the aeration nozzle. This structural relationship minimizes air leakage during air pumping.

3. The invention can be achieved only by the four components of the body, the first nozzle, the second nozzle and the valve plug, and the overall structure is far more compact than the conventional one.
