Detailed Description
For clarity of explanation of the aspects of the present utility model, preferred embodiments are given below in detail with reference to the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the application or uses of the present disclosure. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
As shown in fig. 1 to 3, the safety nozzle for wall roughening for an ultra-high pressure cleaning machine provided by the utility model comprises a nozzle body 1, wherein a universal male head 2 suitable for being connected with the cleaning machine and a plurality of nozzle openings 3 arranged on the nozzle body 1 are arranged on the nozzle body 1, a water flow channel 11 is arranged in the nozzle body 1, the water flow channel 11 is connected with the universal male head 2 and the nozzle openings 3, the axis of the nozzle openings 3 is obliquely arranged, and jet streams 10 sprayed by all the nozzle openings 3 are converged into one or more offset points 4 outside an effective range H. The number of the nozzle openings 3 is at least two, but can also be three, four, six, eight, etc. When the number is relatively large, the two rows of the nozzle openings 3 can be arranged to be in a two-row structure, and the two rows of the nozzle openings are converged to form a plurality of counteracting points 4. In this embodiment, two nozzle openings 3 are provided, two of the nozzle openings 3 are inclined inwards, and the two nozzle openings 3 are adjusted to enable the high-pressure water jet 10 sprayed by the two nozzle openings to be converged into a counteracting point 4 in the effective range H, and two water jets 10 counteract atomization at the counteracting point 4, so that accidental injury of people due to water jets is prevented. The nozzle openings are arranged in parallel and diagonally, when the distance between the nozzle and the wall surface is smaller than the effective range in normal operation, the high-pressure water jet cuts the wall surface to carry out napping, the water jet is injected diagonally at a certain inclination, and the surface stripping effect can be improved; when the high-pressure water jet is started and leaves the wall surface due to misoperation, the two groups of water jets are opposite to each other outside the effective range to eliminate fog, so that the water jet is prevented from injuring people accidentally.
