[0016] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0017] like Figures 1 to 3As shown, it is a schematic diagram of the structure of a water column steady-speed constant-flow injection mechanism provided by the utility model. The water column steady-speed constant-flow injection mechanism includes a mounting rod 10 and a water spray head 20 arranged on one end of the mounting rod 10. It can be imagined that the water column steady-speed constant-flow injection mechanism also includes some other functional structures, such as screw rings, etc., which are well known to those skilled in the art and will not be repeated here.

[0018] One end of the mounting rod 10 is used to set the water sprinkler 20, and the other end is used to connect an external device (not shown). A sensor 11 is arranged on one end of the mounting rod 10 inserted into the water sprinkler 20. The sensor 11 is used to detect water flow and water temperature, so as to provide timely feedback to the operator. The sensor 11 is a prior art and will not be described in detail here.

[0019] The sprinkler head 20 includes a housing 21, a water inlet 22 disposed at one end of the housing 21, a water outlet 23 disposed at the other end of the housing 21, and a constant flow portion 24 disposed in the housing 21 and located between the water inlet 22 and the water outlet 23.

[0020] The central axes of the housing 21 , the water inlet 22 , the water outlet 23 and the constant flow portion 24 all coincide with each other, so that the water flows more evenly from the water inlet 22 into the housing 21 .

[0021] The diameter of the end of the shell 21 close to the water inlet 22 is larger than the diameter of the water outlet 23 , so that the outer contour of the shell 21 is conical, which is convenient for guiding the water flow to flow along the side wall of the shell 21 .

[0022] The water inlet 22 includes a cover plate 221 screwed on the housing 21, and a plurality of water inlets 222 spaced and symmetrically arranged on the cover plate 221. The plurality of water inlets 222 clamp the mounting rod 10 in the middle, thereby fixing the mounting rod 10.

[0023] The cover plate 221 is fixed to the housing 21 by means of snap connection or screw connection, and at least one sealing ring 223 is provided between the cover plate 221 and the housing 21 to prevent water leakage at the joint between the cover plate 221 and the housing 21. The water inlet 222 is protrudingly provided on the cover plate 221 for connection with an external water supply pipe. A limiting ring 224 is provided on the cover plate 221 for limiting the movement of the sensor 11 to prevent the buoyancy of water from causing the sensor 11 to float.

[0024] The outer contour of the water outlet 23 is conical. A vertical opening 25 is provided on one end of the water outlet 23 away from the water inlet 22. The central axis of the vertical opening 25 coincides with the central axis of the water outlet 23. The water outlet 23 is used to converge water flow, so that the water column when the water flows out of the water outlet 23 is fuller and the water column is stable. The inner side wall of the vertical opening 25 gradually tilts and converges from one end close to the water outlet 23 to the other end, and the vertical opening 25 is used to guide the flow direction of the water column to prevent the water column from tilting.

[0025] The constant current unit 24 includes two first slots 241 and a second slot 242 spaced apart from each other in the housing 21 , and two first orifice plates 243 and a second orifice plate 244 respectively disposed in the first slots 241 and the second slots 242 .

[0026] The diameter of the first slot 241 is greater than the diameter of the second slot 242 , so that the second orifice plate 244 can be easily installed in the second slot 242 .

[0027] The first orifice plate 243 and the second orifice plate 244 are both provided with a plurality of through holes 245 at intervals and in a specified manner, for dispersing the water flow and reducing the splashing and impact of the water flow. The middle area of ​​the first orifice plate 243 and the second orifice plate 244 are both provided with a plug hole 246, and the sensor 11 is plugged into the plug hole 246, so that the sensor 11 can detect the water level and water temperature.

[0028] When in use, the first orifice plate 243 and the second orifice plate 244 are respectively installed in the first slot 241 and the second slot 242. The mounting rod 10 and the sensor 11 are inserted into the plug hole 246, and then the cover plate 221 is fixed to the housing 21, and the water inlet 222 is connected to the water supply pipe to fill the housing 21 with water.

[0029] Compared with the prior art, the utility model provides a water column steady speed constant flow ejection mechanism by arranging the water inlet 22, the water outlet 23 and the constant flow part 24 on the shell 21. A plurality of the water inlets 222 are arranged at intervals on the water inlet 22, so that the water flow enters the shell 21 in a dispersed manner, and since the flow rate of each of the water inlets 222 is small, it is easier to adjust. The constant flow part 24 includes two first card slots 241 and a second card slot 242 arranged at intervals in the shell 21, and two first orifice plates 243 and a second orifice plate 244 respectively arranged in the two first card slots 241 and the second card slots 242, and the first orifice plate 243 and the second orifice plate 244 are both arranged at intervals and with a plurality of through holes 245 in a specified manner. This makes the water flow rate of the first orifice plate 243 and the second orifice plate 244 smaller, so that the water can cover all the through holes 245 while flowing down, and the water flow is further dispersed into fine water columns through the through holes 245, so that the water columns can maintain a stable speed to converge at the water outlet 23 and flow out from the water outlet 23. It can be seen from this that the water column steady-speed constant-flow ejection mechanism only needs a low cost to maintain a stable water flow rate during use, and has high practicality.

Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
