when the control air hole is not filled with air, the valve core blocks the main water hole; when the control air hole is filled with air, the air pushes the valve core and the valve rod, and the main water hole is opened.

Furthermore, the cover cap is fixed with the sprayer body through a clamp spring.

Furthermore, a hollow ball head is fixed at the end part of the air pipe quick joint through a fixing nut.

Use the utility model provides a mould spraying shower nozzle, its beneficial effect is: a first sealing ring and a second sealing ring are arranged between the valve core and the inner wall of the sprayer body, the sealing effect is good, and the internal leakage of the sprayer body can be prevented; when the control air hole is not filled with air, the valve core is blocked by the valve rod under the action of the elastic force of the spring, and the valve core can achieve the water locking effect after being used together with the first sealing ring and the second sealing ring, namely, only when the control air hole is filled with air, water containing a release agent can be sprayed out, and the release agent can be prevented from being wasted to a certain extent; when the atomizing device works, high-pressure gas is introduced into the main gas hole, water containing the release agent is converged with the high-pressure gas, and the high-pressure gas is sprayed out after scattering the water, so that the atomizing effect of a product is improved.

Shown in the figure: the nozzle comprises a nozzle body, an inner cavity, a gas pipe quick joint, a control gas hole, a main water hole, a valve core, a valve rod, a spring, a cover cap, a clamp spring, a first sealing ring, a second sealing ring, a fixing nut and a ball head, wherein the nozzle body comprises 1 part, 11 parts, an inner cavity, 12 parts, a gas pipe quick joint, 13 parts, a control gas hole, 14 parts, the main gas hole, 15 parts, the main water hole, 2 parts, a valve core.

Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

as shown in fig. 1-7, a mold spray nozzle includes a nozzle body 1, the nozzle body 1 has an inner cavity 11, the lower end of the nozzle body 1 has an air pipe quick connector 12 communicated with the inner cavity 11, a valve core 2, a valve rod 3, a spring 4 and a cap 5 are sequentially installed in the inner cavity 11 from inside to outside, the valve rod 3 is fixed with the valve core 2, the spring 4 is clamped between the valve rod 3 and the cap 5, the nozzle body 1 is provided with a control air hole 13, a main air hole 14 and a main water hole 15, the control air hole 13, the main water hole 15 is communicated with the inner cavity 11, and the main air hole 14 is communicated with the air pipe quick connector 12.

As shown in fig. 2 and 4, in order to fix the cap 5, the cap 5 is fixed to the head main body 1 by a snap spring 6.

As shown in figures 1 and 4, a hollow ball head 10 is fixed at the end of the air pipe quick connector 12 through a fixing nut 9, the ball head 10 can move, and multi-angle spraying can be realized.

As shown in figure 2, a first sealing ring 7 and a second sealing ring 8 are arranged between the core and the inner wall of the sprayer body 1, the sealing effect is good, and the internal leakage of the sprayer body 1 can be prevented.

When the control air hole 13 is not filled with air, the valve core 2 is enabled to block the main water hole 15 by the valve rod 3 under the action of the elastic force of the spring 4, and the valve core can achieve the water locking effect after being used together with the first sealing ring 7 and the second sealing ring 8, namely, only when the control air hole 13 is filled with air, water containing a release agent can be sprayed out, and the release agent can be prevented from being wasted to a certain extent; when the control gas hole 13 lets in gas, gaseous promotion case 2 and valve rod 3, main water hole 15 is opened, lets in high-pressure gas in the main water hole 14, and the water that contains the release agent joins the back with high-pressure gas, and high-pressure gas breaks up the back blowout with water, has improved the atomization effect of product. When the control air hole 13 is deflated, the spring 4 resets the valve rod 3 and the valve core 2, so that the main water hole 15 is blocked again, and the spraying is stopped.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
