Technical Field

[0001] The invention relates to an aquarium oxygen filling pump, in particular to an electromagnetic oxygen filling pump. Background Art

[0002] Currently, there are three types of small oxygen filling pumps: motor-driven, piezoelectric ceramic, and the more commonly used is electromagnetic-driven. Currently, small electromagnetic oxygen filling pumps are relatively large in size, small in gas volume, low in efficiency, and low in pressure. Summary of the invention

[0003] The object of the present invention is to provide an electromagnetic oxygenation pump, the working principle of which is as follows: an outer conductive magnet, a neodymium permanent magnet (1), an inner conductive magnet and a neodymium permanent magnet (2) form a fixed magnetic field, an annular strong magnetic field gap is formed between the outer conductive magnet, the neodymium permanent magnet (1) and the inner conductive magnet, a neodymium permanent magnet (2) is arranged above the inner conductive magnet, and the use of the neodymium permanent magnet (2) enhances the magnetic field strength of the magnetic field gap. A coil wound on a frame forms an electromagnet, and the coil is placed in the magnetic field gap. When the coil is connected to alternating current, an alternating magnetic field is generated on the coil. Under the interaction of the fixed magnetic field and the alternating magnetic field, the coil is sucked or pushed out in the strong magnetic field gap with the change of the power frequency, generating axial reciprocating motion. The coil frame is fixed to the diaphragm through a multifunctional connecting frame, and the diaphragm also generates reciprocating motion synchronously in the pump body. When the coil is sucked in, the diaphragm in the pump body is pulled out, the air inlet valve opens, the air outlet valve closes, and the air enters the gap between the outer magnetic conductor and the neodymium permanent magnet (1), the inner magnetic conductor, the neodymium permanent magnet (2), the coil and the coil frame, the air inlet pipe (2), and the air inlet valve into the pump body, and the volume of the pump chamber increases; when the coil is pushed out, the diaphragm is pushed into the pump body, the air inlet valve closes, the air outlet valve opens, the volume of the pump chamber decreases, and the air is compressed and discharged. The diaphragm repeats the above process continuously, and the compressed air is continuously discharged from the exhaust port. The large neodymium permanent magnet (1) is arranged in the outer magnetic conductor, and the use of the inner magnetic type reduces the volume, effectively shields the magnetic field, and reduces the leakage magnetic field. The setting of the air inlet path is conducive to taking away the weak heat generated by the coil. The multifunctional connecting frame is also provided with a centering elastic bracket, and the centering elastic bracket and the diaphragm can make the coil and the coil frame suspend in the gap of the strong magnetic field. The diaphragm adopts a double-wave, two-way design suitable for large-amplitude operation, which can reduce power consumption and improve pump efficiency. The side of the end cover facing the pump chamber is concave with an arc. The limit amplitude of the diaphragm being pushed into the pump body coincides with the concave shape. The working amplitude of the diaphragm being pushed into the pump body is less than the limit amplitude. The volume of the pump chamber reaches the minimum in the exhaust state, and more air can be discharged. The centering elastic bracket is corrugated and made of elastic and breathable materials. The multifunctional connecting frame is provided with a through hole to reduce the excessive resistance generated on the multifunctional connecting frame when the coil moves. The assembly shell, the electromagnetic drive part and the pump body part constitute the electromagnetic pump assembly.The assembly shell fixes and seals the electromagnetic drive part and the pump body part in the shell to achieve the first-level isolation and noise reduction; the vibration-damping rubber parts and the vibration-damping rubber parts shaft perform the first-level vibration reduction on the electromagnetic pump assembly; the electromagnetic pump assembly is suspended in the inner shell by the tension spring hanging plate, tension spring, and tension spring hanging parts, so that the electromagnetic pump assembly is suspended in the inner shell, which plays a good vibration reduction and buffering role, and minimizes and absorbs the axial vibration generated by the electromagnetic part. The inner shell also seals the electromagnetic pump assembly, achieving the second-level vibration reduction and second-level isolation and noise reduction; the compressed air discharged from the exhaust port directly enters the end of the inner shell, and the increase in space allows the compressed air to be decompressed. The air is output from the front end of the inner shell through the exhaust pipe. The exhaust port, inner shell, and exhaust pipe constitute an expansion chamber muffler, which further eliminates the noise generated by the electromagnetic drive part and the pump body part, and achieves the third-level noise reduction; the sealed outer shell and anti-vibration foot pad achieve the fourth-level noise isolation and the third-level vibration reduction.
