[0038] The nozzle cavity 3 is arranged at the upper end of the disinfection machine body 1;

[0039] The nozzle cavity 3 is arranged at the upper end of the disinfection machine body 1, and a plurality of openings 301 are opened on the cavity wall of the nozzle cavity 3;

[0041] A nozzle member 5, the front end of which extends out of the nozzle cavity 3, and the rear end of which is located in the nozzle cavity 3 and rotatably connected to the cover plate connecting member 4;

[0042] The limiting assembly 6 is arranged at the rear side of the nozzle component 5 and is used to limit the rotation angle of the nozzle component 5 .

[0043] The nozzle member 5 includes a nozzle 501 and a nozzle connection portion 502 which are integrally arranged and interconnected, the front end of the nozzle 501 extends out of the nozzle cavity 3, the rear end of the nozzle 501 is connected to the front end of the nozzle connection portion 502, and the rear end of the nozzle connection portion 502 is arranged in the nozzle cavity 3;

[0044] The front end of the nozzle connection part 502 is a small-mouth end, and the rear end is a large-mouth end.

[0045] Wherein, the cover plate connector 4 includes a cover plate 401 and two connecting pieces 402. The cover plate 401 is located outside the nozzle cavity 3 and is fixedly connected to the cavity wall of the nozzle cavity 3 through fasteners. A central circular hole is provided on the cover plate 401, and the front end of the nozzle 501 extends out of the nozzle cavity 3 through the central circular hole. The two connecting pieces 402 are symmetrically arranged and are both located on the side of the cover plate 401 facing the nozzle cavity 3. One end of the connecting piece 402 is connected to the cover plate 401, and the other end of the connecting piece 402 is inserted into the nozzle cavity 3 through the opening 301. Preferably, the cover plate 401 is an arc-shaped plate, and the inner arc surface of the arc-shaped plate fits the arc surface of the nozzle cavity 3. The center position of the cover plate 401 is arranged relative to the center position of the opening 301. By providing the connecting piece 402, it is convenient to install the nozzle component 5, and by providing the cover plate 401, the nozzle component 5 can be effectively protected.

[0046] Wherein; the nozzle member 5 has two connecting ears, the center position of the connecting ear is provided with an axial hole 502a, the axial holes of the two connecting ears are symmetrically arranged and the axial direction of the axial hole is perpendicular to and intersects with the axial direction of the nozzle 501;

[0047] The axial hole 502a on the connecting ear is used to insert a limiting shaft (the number is not shown in the figure), and the nozzle connecting part 502 is rotatably connected to the connecting piece 402 of the cover plate connecting part 4 through the limiting shaft. The rotation of the nozzle part 5 is realized by providing the axial hole 502a and the limiting shaft.

[0048] Wherein; the limit assembly 6 includes: a U-shaped fixing seat 601, a top screw 602, a return spring 604, a support block 605 and a card bead 606;

[0049] The U-shaped fixing seat 601 includes two connecting plates arranged opposite to each other and a fixing plate connected between the two connecting plates. The two connecting plates are connected to the two connecting pieces 402 of the cover plate connecting piece 4 through fasteners. One end of the top screw 602 is inserted into the U-shaped fixing seat 601 and fixedly connected to the fixing plate of the U-shaped fixing seat 601. The other end of the top screw 602 is provided with a mounting groove 603. The reset spring 604 and the support block 605 are both arranged in the mounting groove 603. The support block 605 is slidably connected to the inner wall of the mounting groove 603. One end of the positioning spring 604 is fixedly connected to the support block 605, and the other end of the reset spring 604 is fixedly connected to the inner wall of the mounting groove 603. The side of the support block 605 facing away from the reset spring 604 is an arc-shaped surface. The card bead 606 is arranged on the arc-shaped surface of the support block 605 and the top of the card bead 606 protrudes from the mounting groove 603. The end of the nozzle component 5 facing the limiting component 6 has two arc-shaped protrusions, and the two arc-shaped protrusions are symmetrically arranged and have a plurality of arc-shaped card grooves 503 on the surface that are engaged and adapted to the card bead 606.

[0050] When the angle of the nozzle 501 is adjusted by pushing the nozzle 501 upward or pressing the nozzle 501 downward by external force, the nozzle connecting part 502 at its rear end squeezes the card bead 606 under the action of external force, and the card bead 606 is squeezed by the support block 605 under the action of external force and moves toward the inside of the installation groove 603. At this time, the reset spring 604 is in a compressed state. When the angle adjustment of the nozzle 501 is completed, the reset spring 604 releases energy and pushes the card bead 606 into the arc-shaped card groove 503 at the rear end of the nozzle connecting part 502 through the support block 605, thereby ensuring the stable position of the nozzle component 5.

[0051] Since the clamping bead 606 and the nozzle member 5 will rub against each other when adjusting the nozzle angle, in order to reduce wear, the nozzle member 5 is made of wear-resistant elastic material. In this embodiment, the nozzle member 5 is made of elastic plastic and the clamping bead 606 is made of resin. Compared with metal materials, elastic plastic nozzles are easier to make, cheaper, lighter, and more beautiful in appearance.

[0052] Among them, a pump body is arranged at the upper end of the disinfectant storage tank, the liquid inlet of the pump body is connected to the inside of the disinfectant storage tank through a first pipe, and the liquid discharge port of the pump body is connected to the liquid inlet of the spray head 5 through a second pipe. The pump body works to absorb the disinfectant inside the disinfectant storage tank, and finally sprays it out through the spray head 5, so that the disinfection machine can disinfect the outside world. Preferably, the spray heads 5 are located at the same horizontal height and are equidistantly distributed to ensure the comprehensiveness of the disinfection.

[0053] Among them; the upper end surface of the disinfection machine body 1 is provided with a push-pull handrail 2, and the four corners of the lower end surface of the disinfection machine body 1 are provided with universal wheels 101. By providing the push-pull handrail 2 and the universal wheel 101, it is convenient to push the disinfection machine to move and effectively adjust the position.

[0054] The working principle is that the pump body works to absorb the disinfectant inside the disinfectant storage box, and finally sprays it out through the nozzle part 5, so that the disinfection machine can disinfect the outside world. By providing a cover plate connecting part 4, the movable position of the nozzle part 5 can be further limited effectively, and the nozzle part 5 can be protected to a certain extent.

[0055] Furthermore, by setting the limiting axis and the nozzle connection part 502, the nozzle part 5 can rotate around the limiting axis under the action of external force, thereby realizing that the spray angle of the nozzle 501 can be adjusted. During the adjustment process, the arc-shaped groove 503 at the rear end of the nozzle connection part 502 can be clamped or loosened with the clamping bead 606 of the limiting component 6. After the adjustment is completed, the clamping bead 606 cooperates with the arc-shaped groove 502 to lock the position of the nozzle part 5 in time to prevent it from rotating at will.

[0056] 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.
