Problems solved by technology

[0002] During the use of the nozzle, because there are impurities in the conveying medium, if the nozzle is not cleaned in time after the conveying is completed, the nozzle will be blocked after a long time. First, the continuous impact of impurities will cause damage to the nozzle. The injection pressure will also be reduced due to the blockage of impurities, which cannot meet the work needs

Embodiment Construction

[0010] The present invention includes a nozzle body 1 fixedly arranged, a lower nozzle 2 which can move up and down relative to the nozzle body 1 and an upper nozzle 3 fixedly connected to the nozzle body 1 are arranged inside the front end of the nozzle body 1; A space 4 for liquid injection is formed, and a block 5 is provided inside the nozzle body 1 to prevent the lower spray head 2 from over-moving.

[0011] The nozzle body 1 is provided with an inwardly protruding step 6, and the lower part of the lower spray head 2 is provided with a retaining ring 7 that protrudes from the lower spray 2 and the lower spray head 2. Between the step 6 and the retaining ring 7 Establish spring 8.

[0012] The junction between the lower spray head 2 and the nozzle body 1 is provided with a guide rail guide groove structure.

Abstract

The invention relates to a self-cleaning nozzle. The self-cleaning nozzle comprises a nozzle body arranged fixedly. A lower nozzle head capable of moving up and down relative to the nozzle body and an upper nozzle head fixedly connected with the nozzle body are arranged inside the front end of the nozzle body. A space for injecting of fluid is formed between the upper nozzle head and the lower nozzle head. The nozzle body is internally provided with a stop block for preventing the lower nozzle head from moving too fast. The self-cleaning nozzle has the advantages that 1, the nozzle heads are arranged in an up-down mode, mediums pass through the space between the upper nozzle head and the lower nozzle head and are sprayed out, and the injection pressure is formed by adjusting the mediums in the upper nozzle head and the mediums in the lower nozzle head; the stop block for preventing the lower nozzle head from moving too fast is arranged on the self-cleaning nozzle, so that the defect that the lower nozzle head cannot be repositioned due to too fast movement is overcome; and 2, the lower nozzle head can be buffered by arranging a spring when being impacted, and accordingly the situation that the lower nozzle head is damaged due to the fact that the lower nozzle head moves too fast and the impact force is too large is avoided.

Description

technical field [0001] The invention relates to a self-cleaning nozzle, which belongs to the technical field of nozzles. Background technique [0002] During the use of the nozzle, because there are impurities in the conveying medium, if the nozzle is not cleaned in time after the conveying is completed, the nozzle will be blocked after a long time. First, the continuous impact of impurities will cause damage to the nozzle. The injection pressure will also be reduced due to the blockage of impurities, which cannot meet the work needs. Contents of the invention [0003] The purpose of the present invention is to provide a self-cleaning nozzle with simple structure and capable of self-cleaning the nozzle. [0004] For this reason, the technical solution of the present invention is: the present invention includes a fixedly installed nozzle body (1), a lower spray head (2) and a nozzle body (1) that can move up and down relative to the nozzle body (1) are arranged inside the ...
