In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The nozzle structure shown in fig. 1-4 mainly includes a body 1, a first nozzle 2 and a second nozzle 3, a nozzle inlet 11 is formed on the body 1, the nozzle inlet 11 is a circular structural hole, a first flow channel 12 and a second flow channel 13 are respectively formed on the body 1, opposite ends of the first flow channel 12 respectively form a fluid channel with the nozzle inlet 11 and the first nozzle 2, and opposite ends of the second flow channel 13 respectively form a fluid channel with the nozzle inlet 11 and the second nozzle 3. First spray tube 2 be the return bend, second spray tube 3 be straight tube or return bend, specifically:

embodiment mode 1

As shown in fig. 2, a third flow channel 14 is further formed on the machine body 1, two opposite ends of the third flow channel 14 are respectively communicated with the first flow channel 12 and the second flow channel 13, and the first flow channel 12 and the second flow channel 13 are arranged in parallel. In order to facilitate the processing operation of the flow channel on the machine body 1, a plug 5 may be additionally disposed on the nozzle, and accordingly, a plug hole 15 is formed on the machine body 1, the plug hole 15 is communicated with the second flow channel 13, and a sealing structure is formed between the plug 5 and the plug hole 15, as shown in fig. 1 and 2. If the plugging hole 15 is a through hole structure penetrating through the machine body 1, two plugs 5 are needed to seal the outlet of the plugging hole 15.

When fluid enters the nozzle from the nozzle inlet 11, the fluid directly enters the first flow passage 12, one part of the fluid directly enters the first spray pipe 2 and sprays one fluid beam outwards from the first spray pipe 2, the other part of the fluid enters the third flow passage 14 and then directly enters the second spray pipe 3 through the second flow passage 13 and sprays the other fluid beam outwards from the second spray pipe 3, so that the nozzle can spray two fluid beams simultaneously, and the nozzle is simple and compact in integral structure and low in implementation cost.

Embodiment mode 2

As shown in fig. 3, the first flow channel 12 and the second flow channel 13 are arranged in parallel with each other, and the first flow channel 12 and the second flow channel 13 are respectively communicated with the nozzle inlet 11. Compared with embodiment 1, the third flow path 14 is eliminated, so that the hole 15 and the plug 5 can be eliminated, and therefore, the structure is simpler and more compact, and the processing cost is lower.

When fluid enters the nozzle from the nozzle inlet 11, the fluid directly enters the first flow passage 12 and the second flow passage 13 at the same time, and one fluid beam is ejected outwards from the first nozzle 2 and the second nozzle 3 respectively, so that the nozzle can eject two fluid beams at the same time.

Embodiment 3

As shown in fig. 4, the second nozzle 3 is of an elbow structure, an inlet end of the first flow channel 12 is communicated with the nozzle inlet 11, an outlet end of the first flow channel 12 forms a fluid passage with an inlet end of the first nozzle 2 and an inlet end of the second flow channel 13, an outlet end of the second flow channel 13 forms a fluid passage with the second nozzle 3, wherein the first flow channel 12 and the second flow channel 13 are arranged perpendicularly to each other. If the second flow channel 13 is a through hole structure penetrating through the machine body 1, an outlet at one end of the second flow channel is communicated with the second spray pipe 3, and an outlet at the other end of the second flow channel needs to be sealed by a plug 5, which is specifically referred to embodiment 1.

When fluid enters the nozzle from the nozzle inlet 11, the fluid first enters the first flow channel 12 directly and then is divided into two parts from the outlet of the first flow channel 12: one part enters the first spray pipe 2 and sprays one fluid beam outwards from the first spray pipe 2, the other part enters the second flow channel 13 and then directly enters the second spray pipe 3, and sprays the other fluid beam outwards from the second spray pipe 3, so that the nozzle can spray two fluid beams simultaneously.

In order to enable the nozzle to spray a plurality of fluid streams simultaneously, a spray head 4 may be fixedly connected to the outlet end of the first spray pipe 2 and/or the second spray pipe 3. Usually, the nozzle 4 forms a fixed connection structure with the first nozzle 2 and the second nozzle 3 by interference fit or welding, the nozzle 4 is provided with a plurality of nozzles 41, and the plurality of nozzles 41 may be arranged at the side of the nozzle 4. Generally, the central axis of the ejection port 41 forms an angle with the central axis of the head 4 so that the head 4 ejects the fluid beam to a specified position. In addition, the shape of the spray head 4 can adopt a flat square structure, so that the position is limited during assembly, and the fluid beam sprayed by the spray head 4 is directed to a designated position.

When the nozzle is used for cooling and lubricating the piston of an automobile engine, the nozzle inlet 11 on the machine body 1 is connected with the output port of a one-way valve, and the one-way valve can adopt a ball valve type one-way valve or a plunger type one-way valve. When the nozzle works, after the engine oil from the one-way valve enters the nozzle inlet 11, a part of the engine oil enters the first spray pipe 2 through the first flow passage 12 and is sprayed to the bottom of the piston or an oil cooling cavity in the piston through the first spray pipe 2 to cool the piston, and the other part of the engine oil flows through the second flow passage 13 to enter the second spray pipe 3 and then enters the spray head 4, and finally is sprayed to other parts of the piston through the spray port 41 on the spray head 4 to lubricate or cool the other parts of the piston. Therefore, a special cooling oil passage does not need to be specially processed on the inner wall of the connecting rod for cooling, the processing cost is reduced, and the phenomenon that the piston moves and is clamped or even fails due to the blockage of the cooling oil passage in the connecting rod can be prevented.

It should be noted that, in the nozzle structure of the present invention, the first nozzle 2 may adopt a structure as shown in fig. 5, a blind hole 31 and an injection port 32 are respectively formed on the first nozzle 2, an open end of the blind hole 31 penetrates through the first flow passage 12 and the nozzle inlet 11 to form a fluid passage, and the injection port 32 communicates with the blind hole 31. Generally, the injection port 32 is provided at the side of the closed end of the blind hole 31, as shown in fig. 5. Similarly, the second nozzle 3 may also adopt the structure shown in fig. 5, and will not be described herein. With such a structural design, the spray head 4 can be eliminated, which is beneficial for reducing the production cost of the spray nozzle, and through the difference of the number of the arranged spray openings 32, when the fluid enters the spray nozzle from the nozzle inlet 11, the fluid can spray out the fluid beam through the spray openings 32 on the first spray pipe 2, and simultaneously spray out the fluid beam through the spray openings 32 on the second spray pipe 3.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, it should be noted that any modifications, equivalents and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
