The non-handheld high-pressure cleaning machine comprises a cleaning machine main body, a spray gun and a spray head, wherein the spray gun is arranged on a water outlet channel of the cleaning machine main body, the spray head is arranged on the spray gun, a single nozzle or a plurality of nozzles are arranged on the spray head, and after the cleaning machine main body carries out high-pressure treatment on water, the water is sprayed to a target object outwards through the nozzles on the spray head.

According to the prior art, the nozzle is provided with a jet hole and a jet cavity, the hole center line of the jet hole is superposed with the center line of the jet cavity, and the center line of the jet cavity is superposed with or parallel to the center line of the spray head. For example, a single nozzle is arranged at the center of the spray head, and the hole center line of the spray hole and the center line of the spray cavity are coincident with the center line of the spray head; the spray head is provided with a plurality of nozzles which are distributed around the central line of the spray head, and the hole center line of each spray hole and the central line of the spray cavity are parallel to the central line of the spray head. The patent document with the granted publication number of CN 207839213U, the name of which is high-pressure washer and the name of the nozzle applied to the high-pressure washer, discloses a nozzle, which comprises a nozzle shell and a nozzle, wherein the nozzle shell is provided with a base part and a matching part positioned at one end of the base part, and the matching part can be in inserted connection and matching with a water outlet part; the nozzle is connected to the other end of the base; when the matching part is matched with the water outlet part in an inserting mode, the matching part cannot rotate relative to the water outlet part, the water flows from the water outlet part to the sprayer shell and is sprayed out from the nozzle, and the nozzle can rotate relative to the sprayer shell in an operable mode so as to spray out different types of water flows from the nozzle.

When cleaning the object with low height, such as the side of the automobile and the surface of the engine cover of the automobile, the operator can incline the cleaning machine, incline the spray head, and thus incline the water flow sprayed from the spray nozzle, so as to achieve the purpose of cleaning the object. However, the object having a high height can be cleaned by raising the head and spraying the cleaning liquid to the head by the nozzle, and the conventional cleaning machine can also perform a cleaning operation on the object, for example, a ceiling having a high height. However, the high pressure cleaning machine of the prior art has difficulty in cleaning the upper surface of a high-height object, such as the roof of an SUV car or the roof of a medium bus, which is high in height, and an operator lifts the cleaning machine, and the nozzle of the cleaning machine may be slightly higher than the roof, so that the operator cannot wash the roof by pressing the nozzle down, and the effect of effectively cleaning the roof is not achieved.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the high-pressure cleaning machine can effectively clean the upper surface of the object with higher height.

In order to solve the technical problem, the utility model provides a following technical scheme: a nozzle for high-pressure washer is composed of a jet hole and a jet cavity communicated with each other, and the jet direction of the liquid jetted from jet hole is inclined to the central line of jet cavity.

For the hand-held high-pressure cleaning machine, after the cleaning liquid is subjected to high-pressure treatment by the cleaning machine main body, the cleaning liquid passes through the water outlet channel (or referred to as a water outlet part of the high-pressure cleaning machine), the spray head (or referred to as a spray head shell) arranged on the water outlet channel and the spray cavity of the spray nozzle, and is sprayed to a target object from the spray hole of the spray nozzle, so that the target object is cleaned.

For a non-handheld high-pressure cleaning machine, cleaning liquid is subjected to high-pressure treatment by a cleaning machine main body, and then passes through a water outlet channel, a spray gun arranged on the water outlet channel, a spray head arranged on the spray gun and a spray cavity of the spray nozzle, and is sprayed to a target object from a spray hole of the spray nozzle, so that the target object is cleaned.

Because the utility model discloses the injection direction of outwards spraying cleaning liquid through the jet orifice inclines in the central line that sprays the chamber, promptly through the direction of the outwards spraying liquid of jet orifice incline in the central line of shower nozzle also inclines in outlet channel, consequently, places at the cleaning machine level, when outlet channel is put flat promptly, can incline to spray downwards at the upper surface of subject matter through the outwards liquid of spraying jet orifice, effectively washs the subject matter upper surface. The utility model discloses be particularly useful for and highly be higher than operator's height, but be less than the washing of the subject matter upper surface that operator's height adds the arm length.

Detailed Description

A nozzle is applied to a high-pressure cleaning machine.

The nozzle is arranged on the spray head, and particularly for the handheld high-pressure cleaning machine, the spray head is arranged on a cleaning machine main body of the high-pressure cleaning machine, namely the spray head is arranged on a water outlet channel of the cleaning machine main body; for a non-handheld high pressure cleaner, the spray head is mounted on the spray gun.

Referring to fig. 1 and 3, the nozzle is provided with a spray hole 10 and a spray cavity 20 which are communicated with each other, the cleaning liquid is pressed into the nozzle by the cleaning machine main body, and the high-pressure cleaning liquid in the nozzle is sprayed outwards through the spray cavity 20 of the nozzle and the spray hole 10.

The spraying direction of the liquid sprayed outwards through the spraying hole 10 is inclined to the central line of the spraying cavity 20, and the central line 22 of the spraying cavity 20 is parallel to the central line of the spray head and the central line of the water outlet channel.

Any structural design of the injection hole 10, as long as the liquid injection direction injected outwards through the injection hole is inclined to the injection cavity 20, all belong to the structural category of the nozzle of the present invention. Alternatively, the front end 21 of the injection cavity 20 is a curved structure, and the front end of the nozzle is provided with a notch 30, and the notch intersects with the curved structure to form the injection hole 10. The notch 30 may be formed at any position of the front end surface of the nozzle, and the notch 30 may have any shape as long as the injection direction of the liquid injected outward through the injection hole 10 is inclined to the center line of the injection chamber 20.

Referring to fig. 3, since the front end 21 of the spray chamber has a curved structure, the center line of the spray hole 10 may be inclined to the center line of the spray chamber 20, or may be parallel to the center line of the spray chamber 20, and the spray hole is irregular in shape, and the opening of the spray hole is inclined to the center line direction of the spray hole, and the direction of the liquid sprayed out through the spray hole 10 is inclined to the spray chamber 20.

Alternatively, the gap 30 is offset from the center of the nozzle tip, as shown in figures 2, 4 and 5.

Alternatively, as shown in fig. 3, the curved surface structure is a spherical surface, and the curved surface structure can converge the liquid in the injection cavity 20 to increase the pressure of the injection hole 10. The injection hole 10 is located near the center of the nozzle although it is offset from the center of the nozzle, so as to better receive the high-pressure liquid converged by the curved surface structure.

Preferably, as shown in fig. 1, 2 and 3, the slit 30 is a V-shaped slit which can increase the spraying range of the cleaning liquid.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
