The embodiment of the utility model will be described in detail again according to the above drawings.

Intermittent sprayer nozzle (see Figure 1-5) is the main part of the sprayer, with plastic as the main material, it has a threaded ring (14) that is interchangeably screwed with the bottle body, and the main body (2) is connected to the threaded ring with a barb On the top, the main body is provided with a casing (1) that is also surrounded and covered by barbs. The main body has a vertical cavity, an inclined cavity and a horizontal cavity that communicate with each other. The vertical cavity and the inclined cavity are connected by a liquid hole (20) and The air return hole (15) is connected with each other, and the liquid outlet channel (3) is connected between the inclined cavity and the horizontal cavity.

The steel ball seat (17) is pressed into the vertical cavity of the main body (2) from below, and the suction pipe (16) is inserted into the steel ball seat, and the steel ball (18) for opening and closing the valve port is arranged at the upper end, and the steel ball is directly facing the steel ball. Be provided with 6 small ribs (19) that are conical and evenly distributed for positioning steel balls.

There is a piston (5) that can slide axially and a reset piston spring (4) inside the tilting cavity, and a piston seat (6) that slides synchronously with the piston is set outside the piston, and the power of their sliding is driven by the trigger (12). Obtained, the synchronous sliding of the piston and the piston seat is equivalent to two pistons, and the use of double pistons effectively solves the vacuum phenomenon caused by the single-piston spraying, and the two pistons complete their respective functions. The function of spraying will not produce a vacuum phenomenon.

A combing head (9) with a liquid outlet groove tightly matched with the main body is arranged in the horizontal chamber, and the liquid outlet groove on the combing head can be a linear groove (22) for linear spraying; The atomization tank (21), the atomization tank is a chute; it can also have a combination of a linear tank and an atomization tank at the same time, so that it has the functions of linear spray and atomized spray at the same time, and the user can choose one function . The outside of the combing head is a nozzle (10) that can be rotated and adjusted simultaneously with the main body. The nozzle also has a liquid outlet groove (23) and a small liquid outlet hole (11) in the center. The outside of the nozzle is square and the inside is a three-ring concentric body. Structure, the surface of the square four is marked with alignment linear groove, atomization groove and closed logo, for users to choose when using. It not only cooperates with the activity of the main body but also cooperates with the activity of the combing head, so it can be used for rotation adjustment. The liquid outlet groove is arranged on the inner surface of the inner ring. When aligned, the ejected liquid is in a linear shape, when aligned with the atomizing groove (21), the ejected liquid is in an atomized state, and when aligned with a groove-free circular surface, it is in a closed state. The horizontal cavity is also provided with a sealing structure to prevent air backflow. The sealing structure includes a thimble (7) and a spring (8) that are movably fitted in the liquid outlet channel (3). The liquid outlet channel in the horizontal cavity is stepped, so The thimble is also in a matching stepped shape, and the spring supports the thimble to generate pressure during spraying and prevent air from flowing back.

The trigger (12) is connected with the main body (2) with a barb, and its other arm is supported on the concave shoulder at the end of the piston seat (6), so that the power to push the sliding of the piston and the piston seat is input. The cambered surface of trigger is provided with anti-slip structure, and this anti-slip structure can be rib shape (13) or groove shape, and this design selects many evenly distributed rib shapes for use.

When spraying is needed, first select the shape of the liquid outlet of the combing head (9), and the rotary nozzle (10) is from the closed state to align with the linear groove of the combing head or the atomization groove mark. Because the steel ball (18) closes the valve port, the liquid in the bottle has not yet entered the liquid outlet channel (3), that is, the sprayer is in a static state. The suction pipe (16) opens the valve port sealed by the steel ball (18) and enters the inclined cavity, and then pulls the trigger. The process of pulling and loosening is a reciprocating cycle, and the piston (5) and the piston seat (6) ) is also pushed up, and the piston seat is pushed up beyond the air return hole (15), so that the outside air enters the bottle through the air return hole, avoiding the vacuum state in the bottle. When the piston spring (4) resets, the piston seat is pushed down, The air return hole is in a closed state, which can prevent liquid leakage. At the same time, the air in the main body cavity is discharged from the small liquid outlet hole (11) of the nozzle, and the liquid is sprayed out in a linear or atomized form from the liquid outlet channel. After spraying, the thimble (7 ) is sealed under the action of the spring (8) to prevent air backflow, and also completes an intermittent spraying task. The utility model is suitable for occasions requiring intermittent spraying.
