Description

Technical Field

[0001] This utility model relates to a magnetic levitation diaphragm type low-consumption oxygenation pump, and belongs to the technical field of oxygenation pump equipment. Background Technology

[0002] Traditional diaphragm aerator pumps typically use a motor to drive a crankshaft and connecting rod mechanism, which in turn drives the diaphragm to reciprocate and pump air. This mechanical drive method has unavoidable drawbacks: First, there is mechanical friction between moving parts such as the crankshaft and connecting rod, resulting in high energy consumption, low efficiency, and significant mechanical noise and vibration; second, mechanical parts are prone to wear after long-term high-speed operation, affecting the pump's service life and reliability.

[0003] To improve efficiency and reduce energy consumption, patent CN220015430U discloses a magnetic pendulum oxygenation pump body, including a housing. A cylinder head A is fixedly installed at one end of the housing. One end of the cylinder head A has an outlet A, and the other end has an inlet A. The cylinder head A, inlet A, outlet A, and the interior of the housing are interconnected. A cylinder head B is fixedly installed at the other end of the housing. One end of the cylinder head B has an outlet B, and the other end has an inlet B. The outlet B, inlet B, cylinder head B, and the interior of the housing are interconnected. In this invention, the magnet is fixedly mounted on a slider using a mounting bracket, and the slider is connected to... The existing magnetic levitation pump moves horizontally on a straight track, causing the magnet to move horizontally in sync. This alternating motion drives the two rubber cups, resulting in alternating air intake and exhaust from both sides. This achieves stable movement of the magnet and rubber cups, avoiding the displacement of the magnet and rubber cups that can occur with traditional magnetic levitation systems, which would affect air output. However, the core technology of this scheme relies on magnetic drive combined with a mechanical guide rail for sliding, thus solving the problem of poor support stability during rubber cup movement. However, this scheme inevitably suffers from mechanical wear and energy loss due to the use of a mechanical guide rail for limiting movement, and it also inevitably generates noise pollution. Therefore, a magnetic levitation diaphragm-type low-consumption oxygen pump is proposed to address the problems existing in the current technology. Utility Model Content

[0023] See Figures 1-5As shown, the technical solution adopted in this specific embodiment is as follows: It includes an upper cover 1, a filter cover 2, and a base 3. The upper cover 1 and the base 3 are sealed together. The filter cover 2 is located on the top of the upper cover 1. A core seat 4 is provided on the base 3. Two symmetrical coil modules 5 are installed on the inner wall of the core seat 4. A set of magnetic frames 6 is placed between the two coil modules 5. A strong magnet is provided on the magnetic frames 6. There is a radial gap between the inner wall of the coil module 5 and the outer wall of the magnetic frames 6. The magnetic frames 6 are connected to two end cups 7. The edge of the concave surface of the cups 7 is in close contact with the two sides of the core seat 4. In this embodiment, a pure magnetic drive guiding structure is adopted, in which two coil modules and magnetic frames cooperate. The magnetic frames are placed between the coil modules. After being energized, the magnetic frames are located at the center of the magnetic field generated by the coil modules. There is only a very small radial gap between the inner wall of the coil module and the outer wall of the magnetic frames. The radial gap between the frame 6 and the inner walls of the two coil modules 5 is 1mm-2mm. A strong magnet is vertically installed on the magnetic frame. When the strong magnet is in the center of the energized coil, the magnetic resistance of the system is the smallest, the magnetic flux is the largest, and the energy state is the most stable. Once the strong magnet tries to shift to one side due to disturbance, it will deviate from the center position, causing the gap on one side to become smaller and the magnetic resistance to become smaller, while the gap on the other side becomes larger and the magnetic resistance to become larger. This difference in magnetic resistance will generate a strong restoring force (magnetic pull), which will automatically pull the strong magnet back to the center position. This precise radial gap and symmetrical magnetic circuit form an invisible magnetic bearing, which replaces the radial constraint function of the mechanical guide rail, thereby realizing a magnetic levitation structure without mechanical wear. This not only makes the air intake speed faster but also reduces energy consumption and achieves silent operation, bringing a better user experience to the equipment.

[0024] The leather cups on both sides of the magnetic frame are the air intake motion components, the movement base is the actual air chamber, and the space between the top cover and the movement base is the external air intake chamber. Air is drawn in from the air intake chamber by the movement of the leather cups, and then the movement base discharges the drawn-in airflow through the base.

[0025] More specifically, the magnetic frame 6 is provided with fastening screws 601 at both ends to connect with the leather cup 7. In this embodiment, the leather cup is a detachable structure. The leather cup can be disassembled and assembled by the cooperation of the fastening screws and nuts. This is one connection method. Clips or other detachable connection methods can also be used to fix the leather cup. This embodiment does not make specific limitations.

[0026] More specifically, the movement base 4 has circular through holes on both sides that match the cups 7. A cup mating groove 401 is provided on the outside of the through hole. A cup expansion ring 8 is provided in the cup mating groove 401 and mates with the edge of the cup 7. In this embodiment, the cups are fastened to both sides of the movement base and limited by the cup expansion ring to ensure that the cups will not undergo greater deformation.

[0027] More specifically, air chamber sealing gaskets 9 are provided on both sides of the mechanism base 4, and an air chamber 10 is provided on the outside of the air chamber sealing gasket 9 and connected to the mechanism base 4. The air chamber sealing gasket is used to increase the stability and sealing of the connection between the air chamber and the mechanism base, and also to reduce the hard wear between the two, thereby extending the service life of the equipment.

[0028] More specifically, the air chamber 10 is provided with two umbrella valve mounting slots 1001, the mounting slots of the two umbrella valve mounting slots 1001 are in opposite directions, and umbrella valves 13 in opposite directions are provided in the two umbrella valve mounting slots 1001. A valve core hole 1002 is provided in the center of the umbrella valve mounting slot 1001, and the valve core of the umbrella valve 13 is installed in the valve core hole 1002. The two umbrella valves act as one-way valves and are set in opposite directions. When the cup moves linearly, a negative pressure or high pressure will be formed in the core chamber, which will attract or push one of them to be pressed against the umbrella valve mounting slot, while the other will continue to be drawn inward or pushed out to separate from the umbrella valve mounting slot, thereby drawing in external airflow and achieving rapid air intake and pressurization.

[0029] More specifically, the outer side of the air chamber 10 is provided with an air chamber cover sealing gasket 11 and an air chamber cover 12. The air chamber cover sealing gasket 11 located on one side of the umbrella valve 13 is provided with an air passage groove 111. In order to enable the external airflow to enter the inner chamber of the mechanism for circulation, multiple air passage grooves are provided on the air chamber cover sealing gasket. Thus, when the diaphragm cup is evacuated, the airflow enters from the air passage groove. The integrated air passage structure eliminates the need for multiple pipelines, simplifies the equipment structure, reduces production costs, and also improves the production and assembly speed.

[0030] More specifically, the base 3 is provided with a bottom plate sealing gasket 16 and a bottom plate 14 arranged sequentially upwards. The bottom plate 14 is sealed to the base 3 through the bottom plate sealing gasket 16. An exhaust sleeve 15 is provided on the bottom plate 14. An exhaust pipe 402 is provided at the bottom of the movement base 4 and is connected to the exhaust sleeve 15. In this embodiment, the base is a sealed air outlet cavity structure that can buffer a large amount of air. The airflow is discharged from the exhaust pipe at the bottom of the movement base and is sealed to the bottom plate through the exhaust sleeve. A pagoda-shaped air outlet 17 is provided on one side of the base 3 and is connected to the cavity of the base 3. The air is buffered in the base and then output through the pagoda-shaped air outlet.

[0031] More specifically, the core base 4 is provided with four shock-absorbing columns 18 connected to the base plate 14. The core base 4 is also provided with a power cord electrically connected to the coil module 5. In this embodiment, in order to further achieve stable and quiet operation of the equipment and reduce the vibration during operation, four shock-absorbing columns are provided to connect the core base and the bottom. The shock-absorbing columns are preferably made of rubber, which can filter some of the vibration during operation of the core base, thereby obtaining a better quiet effect. The top of the core base 4 is provided with a core base sealing gasket 19 and a core cover 20 in sequence. The core base is sealed by the core base sealing gasket and the core cover to ensure the air outlet effect.

[0032] More specifically, the top of the upper cover 1 is provided with a filter cotton groove 102, and an air inlet pipe 101 is provided in the filter cotton groove 102 and connected to the inside of the upper cover 1. Filter cotton 21 is provided in the filter cotton groove 102 and covers the air inlet pipe 101. In order to ensure the purity of the output airflow, the filter cotton is provided to cover the air inlet pipe, which can filter impurities in the air. Filter cotton with different functions can be placed according to the output requirements.

[0033] The working principle of this utility model is as follows: When the equipment is turned on, the coil module 5 is energized to generate an alternating magnetic field, which drives the magnetic frame 6 to move horizontally between the coil modules 5. The magnetic frame 6 drives the two side cups 7 to move and draw in air. During the air intake process, the two umbrella valves 13 open and close alternately under the air pressure of the core seat 4. The air passage groove 111 on the air chamber cover sealing gasket 11 is connected to the inside of the upper cover 1, so that air can be drawn in from the top air inlet pipe 101. The airflow enters the core seat 4, enters the base 3 from the exhaust pipe 402, and then exits from the pagoda air outlet 17, realizing exhaust and oxygenation. Since there is a very small gap between the magnetic frame 6 and the coil module 5, it can be stably driven by the coil module 5 during movement. There is magnetic resistance in the linear movement. Once a movement deviation occurs, a magnetic resistance difference will be generated. The magnetic frame 6 will be forcibly reset under the action of the magnetic resistance difference, thus realizing magnetic self-stabilizing guidance. There is no mechanical guidance or mechanical friction in the whole process. Therefore, it can not only operate quietly, but also greatly reduce equipment wear and energy consumption.

[0034] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
