[0022] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0023] like Figures 1 to 4 As shown, a plant nutrient solution dissolved oxygen nozzle according to an embodiment of the present invention comprises: a nozzle inlet structure 1, a nozzle outlet structure 2 and a rotating blade structure 3; the nozzle inlet structure 1 is connected to the nozzle outlet structure 2, a stirring space is formed between the nozzle inlet structure 1 and the nozzle outlet structure 2, a rotating blade structure 3 is arranged in the stirring space, the rotating blade structure 3 comprises two rotating blades 301, the rotating blade 301 comprises a blade core 3012 and a plurality of blades 3011 arranged on the blade core 3012, an insertion gap 7 is formed between the blade core 3012 and the plurality of blades 3011, each rotating blade 301 is relatively inserted in the insertion gap 7 of another rotating blade 301, and an air hole 4 is opened on the nozzle outlet structure 2.
[0024] In the embodiment, the number of blades 3011 at the plug-in position of the two rotating blades 301 is in a superimposed state; when the two rotating blades 301 are plugged into each other, the blades 3011 at the plug-in position will form an overlap, and the number of blades 3011 is the sum of the number of blades 3011 of the two rotating blades 301; in this embodiment, the number of rotating blades 301 is two, and in another embodiment, the number of rotating blades 301 may be one or more than two.
[0025] In the embodiment, the number of blades 3011 of the rotating blade 301 is more than two; in this embodiment, the number of blades 3011 of the rotating blade 301 is four, and they are evenly distributed at a ninety-degree angle around the circumference of the blade core 3012 .
[0026] In the embodiment, after the two rotating blades 301 are plugged in, there are eight blades 3011 at the plugging position of the two rotating blades 301, and there are four blades 3011 at both ends of the rotating blade structure at the non-plugging position; wherein the blades 3011 of the two rotating blades 301 form a 45 degree angle, such as Figure 5 As shown; the forty-five degree angle between the blades 3011 ensures that the rotating blade structure 3 fully stirs the nutrient solution without dead angles, while ensuring that the flow of the nutrient solution will not be affected by greater resistance due to too many blades 3011.
[0027] For example, when the number of rotating blades 301 is one, setting less than four blades 3011 on one rotating blade 301 cannot ensure that the nutrient solution is fully stirred and the nutrient solution and oxygen are fully mixed; if more than four blades 3011 are set, such as setting eight blades 3011 on one rotating blade 301, due to the excessive number of blades 3011, both ends of the blade core 3012 need to be set as cylindrical to have enough space to set eight blades 3011 on the blade core 3012; setting eight blades 3011 on one blade core in this way will increase the area blocked by the nutrient solution due to the excessive number of blades 3011 and the cylindrical blade core 3012, thereby increasing the resistance to the flow of the nutrient solution, making the flow of the nutrient solution unsmooth;
[0028] When there are two rotating blades 301 and the number of blades 3011 of the two rotating blades 301 is four, the two rotating blades 301 are plugged at one end of the cylindrical 6 of the blade core 3012. At the plugging position, the number of blades 3011 of the two rotating blades 301 is superimposed, so that eight blades 3011 are formed at the plugging position, and four blades 3011 are respectively formed at the two ends of the plugging position; when the rotating blade structure 3 rotates, the nutrient solution enters from the nozzle inlet structure 1 and is stirred and rotated by the four blades 3011, and the nutrient solution is discharged from the nozzle. When the head outlet structure 2 comes out, the four rotations also rotate it, so that the nutrient solution has sufficient space to diffuse when being stirred; and when the nutrient solution flows through the plug-in position, since the number of blades 3011 at the plug-in position is the superposition of two rotating blades 301, the plug-in position has eight superimposed blades 3011 to stir the nutrient solution; therefore, while ensuring that the nutrient solution has sufficient diffusion space, it can also ensure that the nutrient solution is more fully stirred by the blades 3011 with a larger density, so that the nutrient solution and oxygen are more fully mixed.
[0029] In the embodiment, one end of the blade core 3012 is conical 5, and the other end is cylindrical 6, and the two rotating blades 301 are plugged into each other at one end of the cylindrical 6 of their respective blade cores 3012; the nutrient solution enters from one end of the cone 5 of the blade core 3012 of the rotating blade structure 3, and flows out from one end of the cone 5 of the other blade core 3012 of the rotating blade structure 3; after the two rotating blades 301 are plugged in, the blade cores 3012 at both ends of the rotating blade structure 3 are both conical 5; when the nutrient solution enters from the nozzle inlet structure 1, the structure of the cone 5 makes the nutrient solution subject to less resistance, and when the nutrient solution comes out from the nozzle outlet structure 2, the structure of the cone 5 makes the flow of the nutrient solution smoother.
[0030] In the embodiment, the blade 3011 of the rotating blade 301 is flush with the blade core 3012 at one end of the cone 5, and the blade 3011 extends beyond the cylindrical end surface of the cylindrical 6 of the blade core 3012 at one end of the cylinder 6; the parts of the blades 3011 of the two rotating blades that extend beyond the cylindrical 6 of the blade core 3012 are plugged into each other.
[0031] In the embodiment, when two rotating blades 301 are plugged in, the blades 3011 of the two rotating blades 301 are positioned relative to each other, so that the two rotating blades 301 rotate synchronously and stably; because the blades 3011 of the two rotating blades 301 are tightly attached to each other after plugging in, the two rotating blades 301 are positioned relative to each other, and when one rotating blade 301 rotates, it will drive the other to rotate simultaneously.
[0032] In the embodiment, the nozzle inlet structure 1 is configured to have a larger diameter at one end and a smaller diameter at the other end, and one end of the nozzle outlet structure 2 is configured to be trumpet-shaped. The large diameter end of the nozzle inlet structure 1 is matched and assembled with the trumpet-shaped end of the nozzle outlet structure 2, so that the rotating blade structure 3 is limited to the stirring space; since the diameter of the nozzle inlet structure 1 gradually increases, one end of the nozzle outlet structure 2 is trumpet-shaped, and its diameter gradually decreases; and the circumferential diameter of the rotating blade structure 3 is fixed, and is larger than the small diameter end of the nozzle inlet structure 1 and the nozzle outlet structure 2; therefore, the rotating blade structure 3 is limited to the stirring space formed after the nozzle inlet structure 1 and the nozzle outlet structure 2 are assembled and connected, so as to achieve stable rotation; one end of the nozzle outlet structure 2 is configured to be trumpet-shaped, which can make the nutrient solution flow out more smoothly, and after the nutrient solution and oxygen are mixed, the small diameter end of the trumpet can compress the oxygen-containing nutrient solution, so that the oxygen density in the nutrient solution is increased.
[0033] In the embodiment, the diameter of the nozzle inlet structure 1 gradually increases, and the other end of the nozzle outlet structure 2 is in a cylindrical barrel shape; one end of the nozzle outlet structure 2 is perpendicular to the other end.
[0034] In the embodiment, the air hole 4 is used for oxygen to enter the nutrient solution nozzle, so as to achieve mixing of the nutrient solution with the oxygen after rotation.
[0035] In the embodiment, when the nutrient solution flows in from the nozzle inlet structure 1 and flows out from the nozzle outlet structure 2, a negative pressure is generated during the flow of the nutrient solution, so that air is sucked in from the air holes 4 and mixed with the stirred nutrient solution.
[0036] The complete working process and principle are as follows:
[0037] The nozzle inlet structure 1 is connected to the nozzle outlet structure 2, and a stirring space is formed at the connection for placing the rotating blade structure 3; the nozzle outlet structure 2 is provided with an air hole 4 for the entry of oxygen;
[0038] When the nutrient solution enters from the nozzle inlet structure 1 and flows through the rotating blade structure 3, the flow of the nutrient solution generates an impulse to drive the rotating blade structure 3 to rotate, and the rotation of the rotating blade structure 3 generates a vortex effect, so that the nutrient solution is stirred; when the nutrient solution flows through the air hole 4, a negative pressure is generated during the flow of the nutrient solution, so that air is sucked in from the air hole 4, so that the oxygen in the air is mixed with the nutrient solution, and then the nutrient solution with sufficient oxygen is sprayed out through the nozzle outlet structure 2;
[0039] After the two rotating blades 301 are plugged in, the blades 3011 between the two rotating blades 301 are pressed against each other, so that the blades 3011 are positioned relative to each other; in addition, since the nozzle inlet structure 1 is set to have a larger diameter at one end and a smaller diameter at the other end, and one end of the nozzle outlet structure 2 is set to be trumpet-shaped, the large diameter end of the nozzle inlet structure 1 is matched and assembled with the trumpet-mouth end of the nozzle outlet structure 2, so that the rotating blade structure 3 is limited to the stirring space, and the two rotating blades 301 rotate synchronously and stably for stirring; and the trumpet-shaped nozzle outlet structure can make the flow of the nutrient solution smoother, and after the nutrient solution and oxygen are mixed, the small diameter end can compress the oxygen-containing nutrient solution, so that the oxygen density in the nutrient solution is increased.
[0040] During the stirring process of the nutrient solution, the rotating blade structure 3 includes two rotating blades 301; one rotating blade 301 cannot ensure that the nutrient solution is fully stirred and mixed with oxygen, and the rotating blade 301 with more than four blades 3011 will increase the resistance to the flow of the nutrient solution due to the excessive number of blades 3011, and too many blades 3011 will also cause both ends of the blade core 3012 to be set as cylindrical shapes, so that there is enough space to set so many blades 3011 on the blade core 3012, and both ends of the blade core 3012 are set as cylindrical shapes. When the nutrient solution enters, the cylindrical end surface will also cause the nutrient solution to be more obstructed;
[0041] The two rotating blades 301 are plugged in, so that the number of blades 3011 at the plugging position is eight; and the number of blades 3011 at both ends of the plugging position is four; therefore, the inflow and outflow of the nutrient solution are stirred by four blades 3011, which can ensure that the nutrient solution has sufficient diffusion space to facilitate the full mixing of the nutrient solution and oxygen; and the angle between the eight blades 3011 at the plugging position is 45 degrees, which can ensure that the nutrient solution is stirred at 360 degrees without dead angles;
[0042] When the two rotating blades 301 are plugged in, both ends of the rotating blade structure 3 are cone-shaped 5; the nutrient solution enters from the nozzle inlet structure 1, and the blade core 3012 of the cone 5 makes the nutrient solution encounter less resistance. At the same time, when the nutrient solution flows out from the nozzle outlet structure 2, the blade core 3012 of the cone 5 makes the flow of the nutrient solution more in line with the principle of liquid flow, so that the nutrient solution with sufficient oxygen can flow out more smoothly.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
