Air disc with reverse prevention effect

Abstract

This utility model discloses an air disc with a built-in backflow preventer, comprising a fixedly connected connecting end and a fixed plate. A through-hole plate is fixedly connected to the outer wall of the fixed plate via an mounting sleeve. An inner seat is fixedly connected to the inner wall of the connecting end. A valve core overlaps the top of the inner seat, and a connecting sleeve is sleeved on the outer side of the top of the valve core. In this application, the connecting end is connected to the aerator pump's pipeline via an external thread. During operation, airflow pushes the valve core and connecting sleeve to move, causing the connecting sleeve to abut against the through-hole plate. A gap appears between the valve core and the top of the inner seat, allowing airflow to exit through this gap and the gap between the connecting end and the vertical end of the inner seat. Similarly, when the aerator pump stops running, the connecting sleeve and valve core fall under the combined action of gravity and water pressure, sealing the inner seat and thus achieving the air disc's backflow preventer function. This eliminates the need to assemble a backflow preventer valve on the external pipeline; the air disc can be directly used simply by attaching it to the pipeline, thereby improving the ease of use of the air disc.

Description

Technical Field

[0001] This utility model relates to the field of air pressure plate technology, and in particular to an air pressure plate with a built-in anti-reverse effect. Background Technology

[0002] Air stones are devices commonly used in aquariums, aquaculture, laboratories, and water treatment systems. Their main function is to disperse air into tiny bubbles through microporous materials, thereby increasing the dissolved oxygen content in the water and promoting water circulation.

[0003] Chinese Patent Publication No. CN215422342U, published on 20220107, discloses an aquarium air pump. Its features include an air duct with nano-bubble stones fixed to it, a brushless motor connected to a power source, and an air pump driven by the brushless motor. The air duct has a mounting shell for fixing the nano-bubble stones, preventing them from falling. The air duct has a bend that hooks onto the side wall of the aquarium. The air duct has an access end, and a flexible tube connects the air pump to the access end of the air duct.

[0004] The existing aerator pump is connected to the air stone through a pipeline. In the actual implementation process, considering the problem of water backflow, a check valve needs to be added to the output end of the aerator pump. However, the existing check valve is installed in the pipeline, and it is cumbersome for operators to assemble the air stone, pipeline and check valve. The structure of the air stone can be further optimized. Therefore, it is urgent to propose a corresponding air plate with built-in check function to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gas disc with a built-in anti-reverse function in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gas disc with a built-in anti-reverse function includes a fixed connecting end and a fixed disc. The outer wall of the fixed disc is fixedly connected to a through-hole disc by an installation sleeve. The inner wall of the connecting end is fixedly connected to an inner seat. A valve core is attached to the top of the inner seat. A connecting sleeve is sleeved on the outer side of the top of the valve core. The vertical end of the connecting sleeve is inserted between the horizontal end of the connecting end and the inner seat.

[0008] Preferably, the outer wall of the fixing plate is screwed to the inner wall of the mounting sleeve via threads, and the top of the mounting sleeve is fixedly connected to the through plate via adhesive.

[0009] Preferably, the top of the mounting sleeve has a step, and the through plate fits into the step.

[0010] Preferably, a limiting plate is fixedly connected to the inner wall of the mounting sleeve, the bottom of the limiting plate abuts against the top of the fixed plate, and the top of the limiting plate and the bottom of the through plate form an overflow space for adhesive.

[0011] Preferably, sealing ring one and sealing ring two are respectively engaged and connected on both sides of the vertical end of the fixed plate.

[0012] Preferably, the inner wall of the connecting end is fixedly connected to multiple sets of reinforcing strips, and the multiple sets of reinforcing strips are distributed in a ring.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the connecting end is connected to the pipe of the aerator pump via an external thread. During operation, the airflow pushes the valve core and the connecting sleeve to move. The connecting sleeve abuts against the through plate, and a gap appears between the valve core and the top of the inner seat. The airflow is discharged through this gap and the gap between the connecting end and the vertical end of the inner seat. Similarly, when the aerator pump stops running, the connecting sleeve and the valve core will fall under the combined action of gravity and water pressure, thereby sealing the inner seat and realizing the anti-backflow function of the air plate. There is no need to assemble a check valve on the external pipe. The air plate can be used directly by simply connecting it to the pipe, thereby improving the convenience of using the air plate.

[0015] 2. In this application, the perforation plate and the mounting sleeve are fixed by adhesive. The function of the limiting plate is to limit the screwing of the fixing plate, while the space between the top of the limiting plate and the perforation plate can be used as an overflow notch to prevent excessive overflow of adhesive from flowing into the lower area.

[0023] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A gas disc with a built-in anti-reverse function includes a fixedly connected connecting end 1 and a fixed plate 2. The outer wall of the fixed plate 2 is fixedly connected to a through plate 4 via an mounting sleeve 3. The inner wall of the connecting end 1 is fixedly connected to an inner seat 8. A valve core 10 is overlapped on the top of the inner seat 8. A connecting sleeve 9 is sleeved on the outer side of the top of the valve core 10. The vertical end of the connecting sleeve 9 is inserted between the horizontal end of the connecting end 1 and the inner seat 8.

[0026] The connecting end 1 is connected to the pipe of the oxygenation pump via an external thread. During operation, the airflow pushes the valve core 10 and the connecting sleeve 9 to move. The connecting sleeve 9 abuts against the through plate 4, and a gap appears between the valve core 10 and the top of the inner seat 8. The airflow is discharged through this gap and the gap between the connecting end 1 and the vertical end of the inner seat 8. Similarly, when the oxygenation pump stops running, the connecting sleeve 9 and the valve core 10 will fall under the combined action of gravity and water pressure, thereby sealing the inner seat 8 and realizing the anti-backflow function of the air plate. There is no need to assemble the anti-backflow valve on the external pipe. The air plate can be used directly by simply connecting it to the pipe, thereby improving the convenience of using the air plate.

[0027] See Figure 5 As one embodiment of this application, a flexible hose is connected to the outside of the connection end, and the flexible hose can be connected to a rubber hose, thereby expanding the application scenarios of the air compressor.

[0028] Specifically, such as Figure 2 and Figure 4As shown, the outer wall of the fixing plate 2 is screwed to the inner wall of the mounting sleeve 3 via threads. Its function is to allow this part to be unscrewed directly when the surface of the air stone is blocked and needs to be unblocked, without having to empty the aquarium water and remove the entire component. The top of the mounting sleeve 3 is fixedly connected to the perforation plate 4 via adhesive. The top of the mounting sleeve 3 has a step, and the perforation plate 4 fits into the step, thus ensuring the ease of independent assembly and disassembly of the mounting sleeve 3 and the perforation plate 4. The inner wall of the mounting sleeve 3 is fixedly connected to the limiting plate 5. The bottom of the limiting plate 5 abuts against the top of the fixing plate 2. The top of the limiting plate 5 and the bottom of the perforation plate 4 form an overflow space for adhesive. The perforation plate 4 and the mounting sleeve 3 are fixed by adhesive. The function of the limiting plate 5 is to limit the screwing in of the fixing plate 2, while the space between the top of the limiting plate 5 and the perforation plate 4 can serve as an overflow notch to prevent excessive adhesive from flowing into the area below.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, sealing ring 6 and sealing ring 7 are respectively engaged and connected on both sides of the vertical end of the fixed plate 2 to ensure the airtightness of the air plate connection. Multiple sets of reinforcing strips 11 are fixedly connected to the inner wall of the connecting end 1, and the multiple sets of reinforcing strips 11 are distributed in a ring to guide the airflow better.

[0030] Working principle: Connecting end 1 is connected to the aerator pump pipe via external thread. During operation, airflow pushes valve core 10 and connecting sleeve 9 to move. Connecting sleeve 9 abuts against perforated plate 4, creating a gap between valve core 10 and the top of inner seat 8. Airflow is discharged through this gap and the gap between connecting end 1 and the vertical end of inner seat 8. Similarly, when the aerator pump stops running, connecting sleeve 9 and valve core 10 will fall under the combined action of gravity and water pressure, sealing inner seat 8. This achieves the anti-backflow function of the air plate, eliminating the need to assemble a check valve on the external pipe. The air plate can be used directly by simply attaching it to the pipe, thus improving the convenience of air plate use. Perforated plate 4 and mounting sleeve 3 are fixed with adhesive. The function of limiting plate 5 is to limit the screwing of fixed plate 2, while the space between the top of limiting plate 5 and perforated plate 4 can serve as an overflow gap to prevent excessive overflow of adhesive into the lower area.

[0031] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
