[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, an aeration head with adjustable air volume is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4As shown, an adjustable aeration head according to an embodiment of the present invention includes an aeration pipe 1 and an aeration head body 2. One end of the aeration pipe 1 is fixedly connected to the aeration head body 2, and the surface of the aeration head body 2 is provided with aeration holes 3, which is a common structure in the art. A valve 4 is installed on the surface of the aeration pipe 1, and a gear 6 is fixedly installed on the other end of the valve stem 5 of the valve 4. A valve core is installed inside the valve 4 at one end of the valve stem 5, which is a common structure for valve bodies. A bracket 9 is fixedly installed on one side of the aeration pipe 1, and a guide sleeve 10 is fixedly connected to the other end of the bracket 9. A connecting rod 11 is slidably inserted into the guide sleeve 10. A rack 7 is fixedly installed on the bottom surface of the connecting rod 11, and the rack 7 meshes with the gear 6. A float 12 is fixedly installed on the top surface of the connecting rod 11, and the float 12 floats in the water. On the top surface, when the water level drops, it means the water volume decreases, requiring a reduction in aeration. At this time, float 12 moves downward, and rack 7 moves downward under the gravity of counterweight 8, driving the meshing gear 6 to rotate, which in turn drives valve stem 5 to rotate, closing valve 4 and thus reducing the air intake and aeration of aeration holes 3. Similarly, when the water level rises, it means the water volume increases, requiring an increase in aeration. At this time, float 12 moves upward, and rack 7 moves upward under the pull of float 12, driving the meshing gear 6 to rotate in the opposite direction, which in turn drives valve stem 5 to rotate in the opposite direction, opening valve 4 and thus increasing the air intake and aeration of aeration holes 3. This completes the operation of dynamically adjusting the aeration based on the water level, achieving high automation efficiency, eliminating the trouble of manual adjustment, and improving the convenience and efficiency of use.

[0028] In one embodiment, multiple sets of floats 12 are arranged, and the floats 12 are fixedly connected to each other by a connecting frame 13. The top surface of the connecting rod 11 is fixedly connected to the center of the bottom surface of the float 12 located at the center, thereby improving stability.

[0029] In one embodiment, a counterweight 8 is fixedly installed on the bottom surface of the rack 7, and the counterweight 8 is made of metal, which facilitates the downward movement of the rack 7.

[0030] In one embodiment, a one-way valve 14 is installed on the surface of the aeration pipe 1 upstream of the valve 4, and the one-way valve 14 is installed in the direction in which the airflow exits the aeration head body 2, so as to prevent water from flowing back into the aerator.

[0031] In one embodiment, multiple sets of aeration holes 3 are densely and evenly distributed to expand the aeration range.

[0032] In one embodiment, the bracket 9 has a Z-shaped structure and is made of a metal structure that is not easily deformed, so as to avoid deformation affecting the lifting and lowering of the connecting rod 11.

[0033] In one embodiment, the bottom surface of the connecting rod 11 is integrally connected to the screw 16, and the top surface of the connecting rod 11 is provided with a threaded hole 15. The screw 16 and the threaded hole 15 are threadedly connected, which is a common connection structure. The connecting rod 11 is a round rod, which is extended by the threaded connection between the screw 16 and the threaded hole 15. It is suitable for use in water bodies of different depths, making installation and adjustment more convenient and its application range wider. At the same time, the guide sleeve 10 slides against the connecting rod 11. The guide sleeve 10 guides the lifting of the connecting rod 11, improves the stability of the meshing, and thus improves the stability of the operation.

[0034] In one embodiment, the guide sleeve 10 is arranged vertically, and the inner diameter of the guide sleeve 10 matches the outer diameter of the connecting rod 11. The inner wall of the guide sleeve 10 is polished to facilitate the lifting and lowering of the connecting rod 11.

[0035] Working principle:

[0036] Float 12 floats on the top surface of the water. When the water level drops, it means the water volume has decreased, requiring a reduction in aeration. At this time, float 12 moves downward, and rack 7 moves downward under the weight of counterweight 8, driving the meshing gear 6 to rotate, which in turn drives valve stem 5 to rotate, closing valve 4 and thus reducing the air intake and aeration rate of aeration holes 3. Similarly, when the water level rises, it means the water volume has increased, requiring an increase in aeration. At this time, float 12 moves upward, and rack 7 moves upward under the pull of float 12, driving the meshing gear 6 to rotate in the opposite direction, which in turn drives valve stem 5 to rotate in the opposite direction, opening valve 4. Door 4 increases the air intake and aeration volume of the aeration chamber, enabling dynamic adjustment of aeration volume based on water level. This automated process is highly efficient, eliminating the hassle of manual adjustment and improving ease of use and work efficiency. Furthermore, the connecting rod 11 is a round rod extended via threaded connection between the screw 16 and threaded hole 15, making it suitable for use in water bodies of varying depths. This makes installation and adjustment more convenient and expands its application range. Additionally, the guide sleeve 10 slides against the connecting rod 11, guiding its lifting and lowering and improving engagement stability, thus enhancing operational stability.
