Specific Embodiments

[0018] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model. The present utility model will be described in detail below with reference to the drawings.

[0019] As Figure 1 and Figure 2 shown, a uniform liquid spraying channel structure provided by the present utility model includes a main body 1. The main body 1 is provided with a liquid inlet channel 2, a uniform channel 3, and n liquid outlet channels 4. The outer diameters of the n liquid outlet channels 4 are all different. The n liquid outlet channels 4 are concentrically arranged at the same end of the main body 1. The liquid inlet channel 2 is communicated with the uniform channel 3. One end of the main body 1 is arranged at an acute angle with the uniform channel 3. The uniform channel 3 is communicated with the n liquid outlet channels 4 one by one;

[0020] The width of the uniform channel 3 gradually increases from the end close to the liquid inlet channel 2 to the other end, and n is a natural number greater than 1.

[0021] In actual use, the shape of the liquid outlet channel 4 is annular, that is, multiple liquid outlet channels 4 are concentrically arranged. The working principle of the present utility model is as follows: Water enters the main body 1 from the liquid inlet channel 2, then enters the uniform channel 3 and flows along the uniform channel 3. Since the uniform channel 3 is inclined and communicates with each liquid outlet channel 4, water will enter different liquid outlet channels 4 during the flowing process; and the larger the outer diameter of the liquid outlet channel 4, the smaller the distance between the uniform channel 3 and this liquid outlet channel 4, so as to compensate the time for water to enter the liquid outlet channel 4. In addition, since water is more likely to fill the liquid outlet channel 4 when the outer diameter of the liquid outlet channel 4 is small, the flow rate and pressure of water are adjusted by increasing the distance between the uniform channel 3 and the liquid outlet channel 4, and the time for water to enter and fill the liquid outlet channel 4 can be adjusted, realizing the function of balancing the water outlet effect of each liquid outlet channel 4.

[0022] In this embodiment, the uniform channel 3 is provided with (n - 1) connecting structures 5. The connecting structure 5 includes a straight part 6 and an inclined part 7. The straight part 6 communicates with the uniform channel 3, the straight part 6 is parallel to the liquid inlet channel 2, the inclined part 7 is arranged between the straight part 6 and the liquid outlet channel 4, and the length of the inclined part 7 is negatively correlated with the outer diameter of the liquid outlet channel 4;

[0023] The uniform channel 3 directly communicates with the outermost liquid outlet channel 4.

[0024] Specifically, the heights of the straight parts 6 are basically the same, while the length of the inclined part 7 decreases as the outer diameter of the liquid outlet channel 4 increases. The outer diameter of the straight part 6 is larger than the outer diameter of the corresponding liquid outlet channel 4, and the distance between the projection of each straight part 6 at one end of the main body 1 and the corresponding liquid outlet channel 4 is the same. Through this setting, the distance between the uniform channel 3 and the liquid outlet channel 4 and the length of the inclined part 7 are both negatively correlated with the outer diameter of the liquid outlet channel 4, so as to achieve a better and more accurate effect of adjusting the water pressure and the water outlet rate.

[0025] For the specific coefficient of the above negative correlation, those skilled in the art can calculate it based on the present utility model and will not be elaborated here.

[0026] Specifically, the included angle between the straight part 6 and the inclined part 7 is 90 - 135°, preferably 120°. At the above included angle, water enters the liquid outlet channel 4 obliquely, so that after the water is output through the liquid outlet channel 4, it needs to be blocked and redirected by the inside of the liquid outlet channel 4 before being output, ensuring that the water outlet is not too violent.

[0027] In this embodiment, the liquid inlet channel 2 includes a liquid outlet part 8 and a liquid equalizing part 9. The liquid equalizing part 9 is located on one side of the liquid outlet part 8. The liquid equalizing part 9 communicates with the liquid outlet part 8, the liquid equalizing part 9 communicates with the uniform channel 3, the liquid equalizing part 9 penetrates through both ends of the main body, and n liquid outlet channels 4 are concentrically arranged with the liquid outlet part 8 as the center.

[0028] That is, the liquid outlet part 8 also belongs to the water outlet structure. After water enters from the liquid outlet part 8, a part of it is output from the liquid outlet part 8, and the other part enters the uniform channel 3 along the liquid equalizing part 9, and finally is output by each liquid outlet channel 4.

[0029] Specifically, a communication structure 5 is arranged between the uniform channel 3 and the liquid inlet channel 2. The main function of this communication structure 5 is to balance the water pressure: if the water outlet of the liquid outlet part 8 is too fast, part of the water will be introduced into the uniform channel 3 by the communication structure 5 before output; if the water outlet of the liquid outlet part 8 is too slow, the communication structure 5 will introduce part of the water from the uniform channel 3 into the liquid outlet part 8, achieving the effect of dynamic balance.

[0030] The setting of the liquid equalizing part 9 mainly plays a buffering role to prevent excessive water pressure from entering the uniform channel 3.

[0031] Specifically, the liquid outlet part 8 and the liquid equalizing part 9 are both provided with liquid inlet ports 10, and internal threads 11 are arranged in the liquid inlet ports 10. Both of them can be directly connected to the water source to form a loop with the water source to ensure the stability of the water pressure in the water source.

[0032] Specifically, the main body is provided with an installation part 12. The liquid outlet part 8 and the liquid equalizing part 9 are both arranged between the installation part 12 and the main body 1, and the liquid inlet port 10 is located at the installation part 12.

[0033] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
