[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Please refer to Figure 1-3 A bubble generator includes a mounting frame 1 installed on the inner wall of a fish pond, and a fixing plate 2 installed on one side of the mounting frame 1. The mounting frame 1 has multiple suction cups 8 on one side, and the suction cups 8 are installed on the inner wall of the fish pond. The fixing plate 2 has a sliding plate 13 slidably connected on one side, and a ventilation bend 15 is fixedly installed on one side of the sliding plate 13. A ventilation head 14 is installed at the output end of the ventilation bend 15. An L-shaped telescopic rod 3 is fixedly installed at the upper end of the fixing plate 2, and a sleeve rod 4 is slidably connected at one end of the L-shaped telescopic rod 3. A fixing frame 5 is fixedly installed at one end of the sleeve rod 4, and an air pump 6 is installed on one side of the fixing frame 5. The air pump 6 is connected to the interior of the ventilation bend 15.

[0016] The mounting bracket 1 and suction cup 8 serve as the anchor points for the entire device. The mounting bracket, acting as the main support structure, is attached to the inner wall of the fishpond via multiple suction cups. This installation method offers significant advantages: it eliminates the need for drilling into the fishpond, avoiding damage to the pond structure, and is particularly suitable for glass or acrylic aquariums. It allows for easy installation, disassembly, and repositioning, facilitating pond cleaning and adjustment of the aeration area. The fixing plate is the primary fixing structure mounted on the mounting bracket. The sliding plate and fixing plate are slidably connected, forming the first-stage horizontal movement mechanism of the device. This allows the bubble generating component connected to the sliding plate to move back and forth horizontally along the inner wall of the fishpond. The ventilation bend is an L-shaped or U-shaped pipe fixed to the sliding plate. Its output end is typically fitted with a sand and gravel aeration head, a microporous aeration tube, etc., which is the final component for bubble generation. The bend design allows it to bypass a plane. One end of the L-shaped telescopic rod is fixed to the fixed plate, and the other horizontal end is hollow inside, allowing the sleeve rod to extend and retract. The sleeve rod 4 is fitted inside the L-shaped telescopic rod and its extended length is fixed by locking screws or a locking pin mechanism, thereby realizing vertical adjustment. The fixing bracket 5 is installed at the end of the sleeve rod to support the air pump and subsequent fixing components. The air pump 6 is the power source of the entire system. It is connected to the ventilation bend through a hose and is responsible for compressing air and delivering it to the ventilation head.

[0017] Limiting plates 12 are installed on both sides of the fixed plate 2, and the outer side of the sliding plate 13 is slidably connected to the inner groove of the limiting plate 12. The inner wall of the fixed plate 2 is provided with a sliding block 19 that is slidably connected, and the sliding block 19 is fixedly connected to one side of the sliding plate 13.

[0018] The limiting plate 12 is fixed on both sides of the fixed plate to form a precise guide groove, ensuring that the sliding plate can only slide smoothly in the preset direction and preventing it from shaking or falling out.

[0019] The inner wall of the fixed plate 2 is provided with a lifting screw 18, and the two ends of the lifting screw 18 are rotatably connected to the inner wall of the fixed plate 2 respectively. The sliding block 19 is provided on the outer side of the lifting screw 18. The top of the fixed plate 2 is provided with a waterproof motor 9, and the output end of the waterproof motor 9 is fixedly connected to one end of the lifting screw 18.

[0020] The lifting screw is a precision component that converts rotary motion into linear motion. The threads on the screw match the threaded holes inside the sliding block. A waterproof motor 9 provides power, and its waterproof characteristics ensure electrical safety in the humid environment of the fishpond. When the waterproof motor drives the lifting screw to rotate, the sliding block meshing with the screw cannot rotate, but can only move along the axial direction of the screw, thereby driving the sliding plate fixed to it to move together.

[0021] A connecting pipe 11 is provided on the upper side of the sliding plate 13, and the connecting pipe 11 is connected to the interior of the ventilation bend 15. A connecting stretch hose 10 is provided at the upper end of the connecting pipe 11, and one end of the stretch hose 10 is connected to the air pump 6.

[0022] Among them, the connecting pipe 11 and the stretching hose 10 are designed with dynamic air circuit. Since the sliding plate will move relative to the fixed plate, the air circuit connecting them cannot be a rigid pipe. The stretching hose is usually a spiral protective hose or a silicone hose with good flexibility and extensibility. It can be bent and stretched freely within a certain length range, which perfectly solves the problem of gas transmission between moving parts, ensuring that the air circuit is unobstructed and will not entangle or hinder mechanical movement.

[0023] The lower end of the mounting bracket 5 is fixedly installed with a base plate 7, and the air pump 6 is fixedly installed on the upper side of the base plate 7.

[0024] The base plate 7 provides a sturdy and flat mounting platform for the air pump, ensuring minimal vibration and stable operation during operation.

[0025] The fixing bracket 5 has a fixing bolt 17 inside, and a fixing pad 16 is provided at one end of the fixing bolt 17. The fixing pad 16 is located on the outside of the fish pond.

[0026] The fixing bolt 17 and fixing pad 16 serve as a double safety and reinforcement device for the entire equipment. Although the suction cup provides the main suction force, this mechanical fixing device is crucial for high-power air pumps or to prevent suction cup failure after long-term use. The fixing bolt passes through the fixing frame, and the fixing pad at its end rests against the outer wall of the fish pond. By tightening the fixing bolt, the reaction force firmly "clamps" the entire equipment to the pond wall, greatly enhancing the overall stability and reliability.

[0027] Working principle: The mounting bracket 1 is attached to the predetermined position on the inner wall of the fish pond using suction cup 8. The fixing bolt 17 of the fixing bracket 5 is extended, so that the fixing pad 16 is pressed tightly against the outer wall of the fish pond. The fixing bolt 17 is tightened to firmly clamp the equipment to the pond wall. The horizontal depth of the vent head can be adjusted by sliding the sliding plate 13 directly by hand. The height can be adjusted by pulling the sleeve rod 4. The waterproof motor 9 is started. The motor rotates forward or reverse to drive the lifting screw 18, thereby causing the sliding plate 13 and the vent head to move back and forth automatically. The air pump 6 is started, and the air is compressed. The compressed air flows through the following in sequence: air pump 6 outlet → stretching hose 10 → connecting pipe 11 → vent bend 15 → Finally, the air is discharged from the vent 14. The micropores inside the vent 14 break the air into countless tiny bubbles, which then flow into the water. These tiny bubbles increase the contact area between water and air, improving oxygen dissolution efficiency. The rising bubbles drive water flow, preventing stagnant areas in the fishpond, ensuring uniform water temperature and quality, and mimicking natural water flow, which is beneficial to fish health. The core advantages of this design are its multifunctional integration, adjustable position flexibility, and stable and convenient installation. It is not just a simple air stone, but a complete system integrating support, adjustment, power, and execution functions, solving the problems of fixed position, inconvenient installation, and unsightly appearance of traditional bubble generators, thus possessing high practicality and market value.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
