[0002] The water spraying cleaning device in the cleaning machine mostly comprises a support, a spray head and a water inlet pipe; wherein the water inlet pipe is used for leading water source into the spray head, the spray head is used for spraying water to facilitate cleaning, and the support is used for mounting the spray head. The spray head comprises a rotatable spray head and a non-rotatable spray head. For the rotatable spray head, a rotating mechanism is mostly arranged to drive the rotation of the spray head. In order to ensure the rotation and stability of the spray head, the mounting structure of the spray head is generally complex, which leads to the difficulty in disassembling the spray head, especially when the spray head is in trouble, the whole cleaning device needs to be disassembled from the cleaning machine, which is troublesome. SUMMARY

[0003] The utility model provides a water spraying device on a cleaning machine, aims at solving the problems of complex mounting structure and difficult disassembly of the rotating spray head in the cleaning device in the prior art.

[0004] In order to solve the above technical problems, the utility model adopts the technical scheme that:

[0005] The utility model provides a water spraying device on a cleaning machine, comprising:

[0006] The upper support is provided with an upper positioning part;

[0007] The lower support is detachably connected with the upper support; the lower support is provided with a lower positioning part;

[0008] The spray head is rotatably arranged between the upper positioning part and the lower part; the spray head is provided with a water inlet and a water outlet which are connected in communication; when the water entering the spray head through the water inlet is sprayed from the water outlet, a driving force driving the rotation of the spray head is formed.

[0009] Further scheme: the water outlet comprises a plurality of power ports and a plurality of water spraying ports; the plurality of power ports are symmetrically arranged on the side wall of the spray head; the plurality of water spraying ports are all arranged on the upper surface of the spray head.

[0010] Based on the above scheme, the symmetrical arrangement of the power ports makes the force generated when the water is sprayed from the power ports be able to push the rotation of the spray head. The water sprayed from the water spraying ports can be used for cleaning.

[0011] Further scheme: the power ports are two, and the directions of the two power ports are opposite; the water spraying ports are four, and are respectively located in the front, rear, left and right four directions of the spray head.

[0012] Based on the above scheme, the two power ports are opposite, so that the force direction of the water sprayed is the same, facilitating the rotation of the spray head. The water spray ports distributed in the front, back, left and right directions of the spray head can increase the water spray area, so that the water spray range is larger.

[0013] Further scheme: the lower edge of the upper support is provided with a buckle, the upper edge of the lower support is provided with a buckle groove, and the buckle is detachably connected in the buckle groove.

[0014] Based on the above scheme, the buckle and the buckle groove have a relatively simple structure and are easy to manufacture.

[0015] Further scheme: the upper positioning part is a protruding block arranged at the center of the top of the upper support and protruding downward; the upper end of the spray head is provided with a protruding boss protruding upward; when the spray head is arranged between the upper positioning part and the lower positioning part, the boss is located directly below the protruding block.

[0016] Based on the above scheme, the boss is located directly below the protruding block, which not only plays a positioning role for the top of the spray head, but also avoids upward movement of the spray head when it rotates, ensuring the stability of the spray head when it rotates.

[0017] Further scheme: the lower positioning part is an extension pipe arranged on the lower support and extending downward, and an annular step is arranged on the inner wall of the extension pipe; the lower end of the spray head is provided with an insertion pipe arranged downward along the edge of the water inlet; when the spray head is arranged between the upper positioning part and the lower positioning part, the insertion pipe is inserted in the extension pipe and located directly above the annular step.

[0018] Based on the above scheme, the annular step plays a positioning role for the lower part of the spray head. In addition, the insertion pipe at the lower end of the spray head is inserted in the extension pipe, which has good stability and can ensure that the spray head does not easily separate from the extension pipe when it rotates.

[0019] Further scheme: a water spraying device on a cleaning machine further comprises a water inlet pipe, the upper end of the water inlet pipe is inserted in the extension pipe, and the water inlet pipe enters the spray head through the water inlet of the spray head; the insertion pipe is located between the extension pipe and the water inlet pipe.

[0020] Based on the above scheme, the upper end of the water inlet pipe is inserted in the extension pipe, and the water inlet pipe enters the spray head through the water inlet of the spray head, so that the water in the water inlet pipe can flow smoothly into the spray head, the structure is relatively compact, and the problem of water leakage in the water inlet pipe during flow can be reduced.

[0021] Further scheme: an annular protruding rib is arranged on the outer wall of the water inlet pipe and close to the insertion pipe.

[0022] Based on the above scheme, the annularly arranged convex ribs can reduce the friction force of the plug-in pipe in up-down movement, increase the stability of the nozzle in the up-down direction and the flexibility in the circumferential direction when rotating.

[0023] Further scheme: the extension pipe is provided with an L-shaped clamping groove composed of a horizontal groove and a vertical groove, and the water inlet pipe is provided with a clamping block; the clamping block slides along the vertical groove to the horizontal groove and is locked at the horizontal groove.

[0024] Based on the above scheme, the structure of the L-shaped clamping groove and the clamping block is relatively simple and convenient to operate, so that the extension pipe and the water inlet pipe can be conveniently installed and disassembled. In addition, the structure of the L-shaped clamping groove and the clamping block when being buckled is relatively stable, thereby making the connection between the extension pipe and the water inlet pipe more stable.

[0025] Further scheme: the water inlet pipe is provided with a through hole at a position inside the nozzle, water in the water inlet pipe enters the nozzle through the through hole and is sprayed out of the water outlet.

[0026] Based on the above scheme, the through hole enables water in the water inlet pipe to enter the nozzle, thereby completing nozzle driving by being sprayed out of the power port on the nozzle and completing cleaning by being sprayed out of the water spraying port on the nozzle.

[0027] The beneficial effects of the utility model are as follows:

[0028] In the utility model, the upper support is provided with an upper positioning part, and the lower support is provided with a lower positioning part; the upper support and the lower support are detachably connected, and the nozzle is rotatably arranged between the upper positioning part and the lower positioning part. On the one hand, the detachable connection of the upper support and the lower support makes the installation and disassembly of the nozzle more convenient. On the other hand, the upper positioning part provides positioning for the upper end of the nozzle, and the lower positioning part provides positioning for the lower end of the nozzle, so that the installation of the nozzle is more stable and reliable.

[0029] In addition, the water flow sprayed out of the water outlet of the nozzle provides power for the rotation of the nozzle. Compared with the scheme in the prior art that requires a rotating mechanism to drive the rotation of the nozzle, the utility model only needs to set the water outlet to realize the rotation of the nozzle, and the structure is simpler.
