[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment, this embodiment provides a high-pressure nozzle head with atomization function, such as Figure 1 , Figure 2 as well as Figure 3 As shown, it includes a head 3, one end of the head 3 is provided with an atomizing spray hole distributed in an annular structure, one end of the atomizing spray hole has a small opening, and the other end has a large opening, the end of the atomizing spray hole with a large opening is a liquid inlet, and the end of the atomizing spray hole with a small opening is a spray port, and dust particles placed in the spray port with a small opening enter the atomizing spray hole and cause blockage. The other end of the head 3 is a connecting end with a docking port, a hollow docking part 2, one end of the hollow docking part 2 is inserted into the docking port of the connecting end, and the other end is connected to a hollow external joint 1, and the outer wall of the end of the hollow external joint 1 is provided with an external thread for docking with an external pipe. An annular limiting part is radially extended from one end of the hollow docking part 2 inserted into the head 3, and the hollow docking part 2 is threadedly connected to the docking hole. By rotating the head 3, the docking port can adjust the relative position of the head 3 along the longitudinal direction of the hollow docking part 2, and the annular limiting part can prevent the hollow docking part 2 from detaching from the docking hole. A rubber sealing sleeve 31 is fixed in the head 3 and is located at the opening of the docking port and is slidably sleeved with the hollow docking part 2. The inner wall of the rubber sealing sleeve 31 is provided with a plurality of convex strips of annular structure, which are tightly fitted with the outer wall of the hollow docking part 2 to enhance the sealing performance.

[0025] At the same time, if Figure 2 and Figure 3As shown, a bracket 33 is adjustable on the inner top wall of the head 3, and a plurality of thin rods 34 extending into the atomizing spray hole are fixed on the edge side walls of the bracket 33. The thin rods 34 are synchronously raised and lowered with the bracket 33. An elastic ring 35 with an elliptical structure is fixed on the inner top wall of the head 3, and the bottom wall of the elastic ring 35 is against the upper side wall of the bracket 33; a guide rod 36 slidably plugged with the bracket 33 is fixed on the bottom wall of the elastic ring 35, and an anti-slip expansion part is provided at the end of the guide rod 36. The elastic potential energy of the elastic ring 35 is used to press the bottom wall of the bracket 33 against the end of the hollow docking part 2 in real time, and the anti-slip expansion part prevents the bracket 33 from being separated from the guide rod 36. The rotating head 3 can adjust its position relative to the hollow docking part 2, and at the same time, the end of the hollow docking part 2 is used to push the bracket 33 to move synchronously, thereby adjusting the position of the thin rods 34. A sealing adjustment block 341 is sleeved on the outer wall of the thin rod 34, and a gap is provided between the sealing adjustment block 341 and the atomizing spray hole. The sealing adjustment block 341 is a rubber block or a stainless steel ball with a spherical structure, such as Figure 3 As shown, whether the sealing adjustment block 341 is a rubber block or a stainless steel ball, it follows the thin rod 34 to adjust the relative position and adjust the gap between it and the inner wall of the atomizing nozzle hole. In addition, the diameter of the sealing adjustment block 341 is not less than the inner diameter of the end with the smaller opening of the atomizing nozzle hole, so as to prevent the sealing adjustment block 341 from extending out of the atomizing nozzle hole.

[0026] The distance of the sealing adjustment block 341 relative to the end with the smaller opening of the atomizing spray hole can be adjusted, and the position of the head 3 relative to the end of the hollow docking part 2 is adjusted, thereby driving the multiple thin rods 34 on the edge side wall of the bracket 33 to be raised and lowered synchronously, so as to facilitate the use of the thin rods 34 to clear the atomizing spray hole and avoid blockage that affects the normal injection of the fluid. At the same time, the sealing adjustment block 341 adjusts the distance relative to the end with the smaller opening of the atomizing spray hole, so that the size of the gap between the sealing adjustment block 341 and the atomizing spray hole is adjusted synchronously, thereby adjusting the caliber of the liquid sprayed from the atomizing spray hole, that is, adjusting the pressure of the fluid injection. The greater the pressure, the fluid will adjust from the water column shape to the atomized shape, and realize the adjustment of multiple fluid injection states by one hole. According to the requirements of the fluid injection state, the user only needs to rotate the head 3 by hand relative to the hollow docking part 2 to adjust the position of the atomizing spray hole of the head 3 relative to the sealing adjustment block 341, that is, adjust the size of the gap. The smaller the gap, the faster the flow rate of the fluid flowing through the gap, and the fluid is sprayed in the form of atomization. On the contrary, the larger the gap, the slower the fluid speed, the slower the water column jet speed, the larger the water column diameter, and the fluid will not be atomized.

[0027] In this embodiment, a tray 21 is provided at the bottom end of the outer wall of the hollow docking part 2, and the hollow docking part 2 is sleeved with a spring 22 clamped between the tray 21 and the head 3. The elastic force of the spring 22 is used to press between the tray 21 and the hollow docking part 2, and there is friction between the head 3 and the end of the spring 22, which will increase the resistance to the rotation of the head 3 relative to the hollow docking part 2.

[0028] Furthermore, a plurality of reinforcing rods 32 are fixed to the inner bottom wall of the head 3. The reinforcing rods 32 are laterally provided with lifting sliding holes that are slidably connected to the bracket 33. The bracket 33 slides in the lifting sliding holes of the reinforcing rods 32 to assist in enhancing the stability of the bracket 33 sliding in the axial direction of the guide rod 36.

[0029] In a further embodiment, Figure 2 and Figure 4 As shown, it also includes a flow guide member arranged in the hollow external joint 1, and the flow guide member includes two spherical baffles 41, one of which is fixed on the side wall of the intersection of the hollow external joint 1 and the hollow docking part 2, and the baffle 41 blocks the passage into the hollow docking part, and the upper part of the hollow external joint 1 is a spherical cavity, and the radial distance between the other baffle 41 and the inner wall of the spherical cavity is S, which facilitates the flow to be introduced into the spherical cavity from the end of the hollow external joint 1. A flow guide pipe 4 is fixed between the two baffles 41, and a flow guide hole is opened on the radial side wall of the flow guide pipe 4. The end of the flow guide pipe 4 passes through a baffle 41 near the hollow docking part 2. The flow entering between the two baffles 41 will flow between the two spherical baffles 41 to form a vortex, and at the same time, the fluid enters the flow guide pipe 4 from the flow guide hole on the radial side wall of the flow guide pipe 4, and enters the hollow docking part 2 from one end passing through the baffle 41. The advantage of the eddy current is that it can continuously change the position of the fluid and the impurities mixed in the fluid between the two baffles 41, thereby preventing the impurities from docking at the guide holes of the guide tube 4, which may easily affect the fluid flow rate and cause blockage.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
