Abstract

The invention discloses a spray head of a wave power pushing structure, which comprises a shell of the spray head and an inner cavity and is characterized in that the inner cavity is detachable; the detachable inner cavity comprises a conical inner cavity and at least one ellipsoidal inner cavity; both ends of the ellipsoidal inner cavity are open; a small mouth of the conical inner cavity is communicated with the ellipsoidal inner cavity; and firstly, the conical inner cavity is used for acceleration, and then, the ellipsoidal inner cavity is used for acceleration, and thus, an acceleration effect is obvious.

Description

Wave power-driven injection head

Technical field

The present invention relates to a kind of injector head, particularly a kind of spray chamber volume has the injector head of continuous size variation.

Background technology

Injection nozzle structure on general injection machine, comprise as shown in Figure 1 shell (1) and inner chamber (2), its inner chamber is the oval cone-shaped that is shaped as two open ends, after jetting material enters inner chamber, progressed into the part of less volume by the part of larger volume in inner chamber, jetting material is accelerated after being squeezed in this process, but the acceleration effect of this structure is not very desirable.

Summary of the invention

Goal of the invention of the present invention is in order to overcome the shortcoming described in the above-mentioned background technology, the injector head of the good wave power pushing structure of a kind of acceleration effect to be provided.

Technical scheme of the present invention is: a kind of wave power-driven injection head, comprise injector head shell and inner chamber, described inner chamber is removable inner chamber, this removable inner chamber comprises cone inner chamber and at least one ellipsoid inner chamber, the both ends open of ellipsoid inner chamber, the osculum of cone inner chamber is communicated with the ellipsoid inner chamber, also is provided with on the injector head shell to screw spiral shell and emit, removable inner chamber is packed in the inner chamber of injector head shell, and turn screws spiral shell and emits and fix.

Described removable inner chamber can comprise the ellipsoid inner chamber of a cone inner chamber and three series windings, and the volume of three ellipsoid inner chambers is descending, and wherein capacious ellipsoid inner chamber is communicated with the osculum of cone inner chamber.

Described ellipsoid inner chamber comprises the two parts that vertically are divided into two from the centre.

Jetting material enters inner-cavity structure of the present invention, at first passes through the acceleration of cone inner chamber, and then the ellipsoid inner chamber accelerates, and acceleration effect is better than independent cone inner chamber.

Wherein: 1, shell, 2, inner chamber, 21, shell, 22, screw spiral shell and emit, 23, jet, 24, the cone inner chamber, 25, the ellipsoid inner chamber, 31, the cone inner chamber, 32, the ellipsoid inner chamber.

The specific embodiment

As shown in Figure 2, embodiment 1 comprises shell (21), also be provided with on shell (21) and screw spiral shell and emit (22, the shell front end is jet (23), it is a cylindrical space in shell, removable inner chamber loads wherein, the removable inner chamber of this embodiment comprises the ellipsoid inner chamber (25) of cone inner chamber (24) and two two open ends, cone inner chamber and ellipsoid inner chamber are connected successively, the ellipsoid inner chamber that wherein osculum of cone inner chamber and cavity volume are large is communicated with, and then the little ellipsoid inner chamber of communication with cavity volume, be communicated at last jet.The ellipsoid inner chamber is comprised of the two parts that vertically separate from the centre.

Removable inner chamber in embodiment 2 comprises a cone inner chamber (31) of series connection successively and the ellipsoid inner chamber (32) of three arrogant both ends opens that diminish of cavity volume as shown in Figure 2, and the ellipsoid inner chamber is comprised of the two parts that vertically separate from the centre.

Claims
