In the prior art, as shown in fig. 1, after the spray head of the cleaning machine sprays liquid, part of the liquid impinges on the water blocking surface 31 of the water blocking member 3, and under the reaction, the part of the liquid flows back to the connecting member 2 along the water blocking surface 31, and finally the liquid loses speed and drops under the action of gravity, but under the condition, the liquid sprayed by the spray head of the cleaning machine can be influenced, so that the sprayed liquid cannot be atomized well, the surface to be cleaned cannot be wetted uniformly, and the cleaning effect of the cleaning machine can be influenced finally.
In order to solve the above problems, as shown in fig. 2-5, the present embodiment provides a spray head of a cleaning machine, including: the spray head comprises a spray head main body 1, wherein a liquid outlet channel 11 is formed in the spray head main body, and an outlet 13 of the liquid outlet channel is positioned on the front end face 12 of the spray head main body; the rear end face of the connecting piece 2 is connected with the front end face 12 of the nozzle body, and the connecting piece 2 does not shade the outlet 13 of the liquid outlet channel; in a possible implementation, the connecting piece 2 may be arranged horizontally or may have a certain angle with the horizontal plane, as long as the connecting piece 2 does not block the outlet 13 of the liquid outlet channel. The water retaining member 3 is obliquely arranged, one surface of the water retaining member 3 facing the spray head main body 1 is a water retaining surface 31, and the upper end of the water retaining member 3 is connected with the front end surface of the connecting member; the front end surface of the connecting piece is provided with a step surface 22 which transits to the water blocking surface 31, so that the liquid flowing back along the water blocking piece 3 is ejected along the water blocking surface 31 of the water blocking piece 3 after impacting the step surface 22. When the liquid is sprayed out from the outlet 13 of the liquid outlet channel, part of the liquid impacts the water blocking surface 31 of the water blocking part 3, when the part of the liquid flows to the step surface 22 along the water blocking surface 31 under the reaction, the liquid backflow path is reduced, so that the liquid flows to the step surface 22 at a certain speed, can be sprayed out along the water blocking surface 31 under the reaction of the step surface 22, still has an atomization effect, does not generate a liquid dropping phenomenon, and does not influence the liquid spraying effect of the spray head.
In a possible implementation, as shown in fig. 2 and 3, the water blocking surface 31 is a sector, which conforms to the flow state of the liquid, and the flow of the liquid in the liquid outlet channel 11 is similar to a laminar flow state, but when the liquid flows out of the outlet 13 of the liquid outlet channel, the liquid is in a parabolic state under the action of gravity, and the sector can be similar to the flow shape of the liquid. In one possible implementation, the central angle α of the sector may be adjusted according to the liquid outlet angle, when the spray area of the liquid sprayed by the spray head is large, the angle of the central angle α of the sector may be increased accordingly, and when the spray area of the liquid sprayed by the spray head is small, the angle of the central angle α of the sector may be reduced accordingly, so that the size of the central angle α of the sector may be adapted to the spray area of the liquid. The central angle α of the fan-shaped surface is also related to the connection relationship between the connecting piece 2 and the water blocking piece 3, in this embodiment, because the top view of the front end surface of the connecting piece is in a middle concave shape, and the top view of the upper end of the water blocking piece 3 is in a middle convex shape, the central angle α of the fan-shaped water blocking surface 31 is smaller than 180 degrees; if the top view of the front end surface of the connecting piece is in a middle convex shape, the top view of the upper end of the water retaining piece 3 is in a middle concave shape, and accordingly, the central angle alpha of the fan-shaped water retaining surface 31 is larger than 180 degrees but always smaller than 360 degrees; similarly, when the top view of the front end surface of the connector is in a flush state, and correspondingly, the top view of the upper end of the water blocking member 3 is also in a flush state, the central angle α of the fan-shaped water blocking surface 31 will be equal to 180 degrees.
In a possible implementation, the height H of the step surface 22 may be adjusted according to the flow rate of the liquid, and when the flow rate of the liquid is high, and part of the liquid flows back to the step surface 22, the situation that the liquid impacts on the connecting piece 2 beyond the step surface 22 may occur, so that the height H of the step surface 22 may be increased to reduce the occurrence of the situation; similarly, when the flow rate of the liquid is slow, the height H of the stepped surface 22 can be reduced correspondingly.
In a possible implementation, as shown in fig. 4-6, the connecting piece 2 is located at the upper part of the outlet of the liquid outlet channel 11, so that the outlet 13 of the liquid outlet channel is not blocked, and the liquid spraying effect of the sprayer is not affected. In a possible implementation, when the connecting member 2 is arranged horizontally, it is necessary that the lowest point of the connecting member 2 is not lower than the highest point of the outlet 13 of the liquid outlet channel, and the lowest point of the connecting member 2 may be just on the same vertical level as the highest point of the outlet 13 of the liquid outlet channel, or the lowest point of the connecting member 2 is higher than the highest point of the outlet 13 of the liquid outlet channel. The connecting piece 2 has an inner side 23 close to the outlet and an outer side 24 opposite the inner side 23. The step surface 22 is inclined from the inner side surface 23 to the outer side surface 24. It will be understood that the accommodating space can be formed between the step surface 22 and the water blocking surface 31, so that the liquid flowing back can stay in the accommodating space at a moment after striking the step surface 22, and does not flow back from the accommodating space to the inner side surface 23 of the connecting member 2, thereby causing the liquid dripping phenomenon. In one possible implementation manner, the step surface 22 is perpendicular to the inner side surface 23 and the outer side surface 24, the connecting piece 2 is horizontally arranged, the inner side surface 23 and the outer side surface 24 are parallel to the horizontal plane, the step surface 22 is perpendicular to the inner side surface 23 and the outer side surface 24, that is, the step surface 22 is a vertical surface perpendicular to the horizontal plane, and at this time, the step surface 22 can still prevent liquid from flowing back to the connecting piece 2 beyond the step surface 22, so that the dripping phenomenon is prevented. In a possible implementation manner, the connecting piece 2 and the water retaining piece 3 are integrally formed, so that the integration of the connecting piece 2 and the water retaining piece 3 can be increased, errors generated at the step surface 22 by the water retaining piece 3 and the connecting piece 2 due to assembly and the like are reduced or even avoided, and the kinetic energy of the backflow liquid is absorbed, and the speed is reduced so that the backflow liquid cannot be ejected along the water retaining surface 31.
In one possible implementation, as shown in fig. 4 and 5, the lower end of the water guard 3 is inclined away from the nozzle body 1, so that the flow characteristics of the liquid are more consistent, because the flow of the liquid is gradually dispersed when the liquid is not restrained by the pipe, and the flow of the liquid is more favored when the distance between the lower end of the water guard 3 and the nozzle body 1 is within a certain range.
The application still provides a cleaning machine, including clear water pipe (not shown in the figure) and the shower nozzle of application foretell cleaning machine, clear water pipe and drain channel 11 fluid intercommunication, and the during operation of cleaning machine is filled with liquid in the clear water pipe, and liquid can be water, also can be the cleaning solution of mixed water, and in the liquid of clear water pipe flowed the shower nozzle of cleaning machine, the surface of the object of waiting to clean was sprayed again.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
