Description

Technical Field

[0001] This invention relates to the field of diaphragm pump technology, and in particular to an electromagnetic diaphragm pump. Background Technology

[0002] A diaphragm pump is a type of conveying machinery widely used in disciplines such as biology, chemistry, and chemical engineering. It is primarily used for extracting fluids such as gases and liquids. It relies on the reciprocating movement of a diaphragm to change the volume of the working chamber, thereby drawing in and discharging fluids. Currently, there are many types and models of diaphragm pumps on the market. Diaphragm pumps can be categorized by their function and characteristics, including solenoid valve, electronic, intelligent, and fieldbus-type diaphragm pumps.

[0003] An electromagnetic vibrating diaphragm pump, also known as an electromagnetic diaphragm pump, comprises a diaphragm made of rubber, fixed to both ends of an oscillator equipped with magnets, and an electromagnet positioned facing the magnets on the oscillator. The oscillator and electromagnet are enclosed in a housing, which covers the outer diaphragm. The housing includes a compression chamber adjacent to the diaphragm, an intake chamber adjacent to the compression chamber, and a discharge chamber adjacent to the compression chamber. The intake chamber is controlled unidirectionally by an intake valve, and the discharge chamber is controlled unidirectionally by a discharge valve. Furthermore, the oscillator vibrates according to changes in the polarity of the electromagnet, which in turn changes according to the phase of an alternating current power supply applied to the electromagnet, causing the diaphragm to vibrate, thereby repeatedly drawing in and expelling fluids such as air.

[0004] Existing electromagnetic diaphragm pumps typically require an air chamber structure to pump the gas drawn in inside the pump body to the air storage chamber. Since the internal chamber of the electromagnetic diaphragm pump needs to be connected to the outside air through an air intake component, negative pressure is created during pumping to extract and transport the fluid. In existing technologies, to ensure the airtightness of the internal chamber, the air inlet of the electromagnetic diaphragm pump is generally set very small. However, a small air inlet area reduces the efficiency of the electromagnetic diaphragm pump.

[0005] Furthermore, the air chamber structure of an electromagnetic diaphragm pump must ensure airtight connection with both the pump body assembly shell and the air storage structure. Poor assembly sealing can easily lead to poor airtightness. In addition, based on its motion process, the air output mode of existing electromagnetic diaphragm pumps is generally a discontinuous pulsating flow. If an additional air storage structure with a sealed space is added outside the pump body, the diaphragm pump will increase in size and the assembly structure will be more complex. This will also increase the probability of gas leakage or malfunction during use, affecting the performance of the diaphragm pump. Summary of the Invention

[0006] In view of this, the present invention aims to provide an electromagnetic diaphragm pump to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0017] Furthermore, a first receiving groove is provided on the air intake plate, and two third connecting holes are provided on the first receiving groove. The air intake component is installed in the first receiving groove, and two sets of air intake groups are provided on the air intake component.

[0019] Furthermore, a sponge is provided in the second receiving groove between the first plate and the air intake plate.

[0020] Furthermore, the air chamber assembly includes an air chamber shell and a cover plate. The cover plate covers one side of the air chamber shell. The air chamber assembly is detachably connected to the first mounting side plate of the shell. The interior of the shell forms a cavity for accommodating the electromagnetic component. A first connecting nozzle, a positioning boss, and a second connecting hole are provided on the first mounting side plate. Correspondingly, a first connecting hole, a plug-in hole, and a second connecting nozzle are provided on the air chamber shell. The first connecting nozzle is inserted into and communicates with the first connecting hole, and the second connecting nozzle is inserted into and communicates with the second connecting hole. The first connecting hole communicates with the cavity, and the second connecting hole communicates with the air storage box. The positioning boss can be inserted into the plug-in hole for positioning. The center lines of the first connecting hole, the plug-in hole, and the second connecting nozzle are collinear.

[0021] Furthermore, the air chamber outer shell includes a housing portion, within which a first air chamber is disposed. The first air chamber is sealed by the cover plate.

[0024] Compared with existing technologies, the electromagnetic diaphragm pump of the present invention has the following advantages:

[0025] (1) The electromagnetic diaphragm pump of the present invention improves the air inlet structure, the air outlet structure of the air chamber assembly and the structure of the air storage box, making it compact, easy to install, stable in connection and highly airtight, thus greatly improving the working performance of the electromagnetic diaphragm pump.

[0026] (2) The electromagnetic diaphragm pump of the present invention reduces the flow area of ​​a single air inlet while ensuring the total air inlet flow area, preventing foreign objects from entering the cavity through the air inlet and causing malfunction or component damage. At the same time, it improves the suction efficiency of the electromagnetic diaphragm pump when pumping and enhances the reliability of the electromagnetic diaphragm pump.

[0027] (3) The electromagnetic diaphragm pump of the present invention improves the accuracy and connectivity of the assembly of the air chamber assembly and the housing by improving the assembly structure of the air chamber assembly and the housing, thereby improving the installation efficiency, ensuring the stability and sealing of the component connection, and improving the reliability of the normal operation of the electromagnetic diaphragm pump.

[0028] (4) The electromagnetic diaphragm pump of the present invention forms a baffled flow path structure inside the gas storage box. By changing the flow direction and speed of the airflow, the gas stays in the gas storage box for a longer time, which reduces the impact of the pulsed gas discharge mode of the gas chamber component. This makes the gas discharged by the exhaust component of the electromagnetic diaphragm pump of the present invention more uniform and stable, and avoids turbulence. Attached Figure Description

[0053] Example 1

[0054] like Figures 1-17 As shown, the present invention discloses an electromagnetic diaphragm pump, comprising:

[0055] The housing 1 has a chamber 108 formed inside it for accommodating the electromagnetic component 5;

[0056] Air intake component 2, on which a first air intake port 203 is provided;

[0057] The air chamber assembly 3, under the action of the electromagnetic component 5, injects external air into the chamber 108 on the housing 1 through the air inlet 2, and discharges the air in the chamber 108 to the air storage box 104.

[0058] The end plate 6 can simultaneously cover the opening of the housing 1 and the opening of the gas storage box 104;

[0059] Air outlet 4 is used for exhausting air from the air storage box 104.

[0060] The housing 1 includes an air intake plate 101 and a mounting side plate. The air intake plate 101 and the mounting side plate are arranged to form a frame structure with an opening at one end and a cavity 108 inside. The opening of the housing 1 is opposite to the air intake plate 101 on the housing 1. A plurality of plug-in plates 1013 are provided at one end of the mounting side plate away from the air intake plate 101. A slot 601 is provided on the end cap plate 6. The plug-in plates 1013 are plugged into the slot 601. A limiting plate device 1014 is provided on the inner wall of the mounting side plate. The limiting plate device 1014 is used to fix the electromagnetic component 5. The air storage box 104 is located on the outer side of the mounting side plate. The air intake plate 101, the mounting side plate, the air storage box 104, the plug-in plates 1013, and the limiting plate device 1014 are integrally formed.

[0061] This design discloses an electromagnetic diaphragm pump. By improving the structure of the housing 1 of the electromagnetic diaphragm pump, the air storage box 104, the plate structure forming the chamber 108, the limiting plate device 1014 for installing the electromagnetic component 5, and the plug plate 1013 for positioning and connecting with the end plate 6 are integrally formed. This allows the housing 1 to be integrally formed by injection molding, which is convenient for processing and production and improves production efficiency. At the same time, it can improve the processing accuracy of the positioning structure, connection structure and sealing structure on the housing 1, and improve the stability and sealing of the connection of each component of the electromagnetic diaphragm pump.

[0062] Preferably, four plug-in plates 1013 are provided on the mounting side plate, and the forces exerted on any two adjacent plug-in plates 1013 when inserted into the slots 601 are arranged at an angle. Specifically, the four plug-in plates 1013 are arranged in two groups, with the forces exerted on the two plug-in plates 1013 in each group when inserted into the slots 601 being opposite, and the forces exerted on the two plug-in plates 1013 in different groups when inserted into the slots 601 being perpendicular. This arrangement further improves the rapid positioning and assembly of the housing 1 and the end plate 6, which are then fastened with connecting screws. During assembly, one person can quickly complete the assembly of the housing 1 and the end plate 6, resulting in extremely high installation efficiency and ensuring stable connection.

[0063] As a preferred example of the present invention, the mounting side plate includes two first mounting side plates 102 and two second mounting side plates 1012, which form a rectangular frame structure. A mounting boss 109 is provided on the first mounting side plate 102, and a mounting hole 103 is provided at the center of the mounting boss 109. An air chamber assembly 3 is fixed on each mounting boss 109. The air chamber assembly 3 is fixed on the first mounting side plate 102 and covers the mounting hole 103. The air storage box 104 is disposed on one of the second mounting side plates 1012.

[0064] This design discloses an installation side plate structure for the housing 1, which achieves a reasonable layout of the chamber 108 structure and the air storage box 104 structure, improves the structural strength of each component, ensures that each component can be correctly installed and positioned, has a reasonable structure, improves the convenience of installation of each component and the stability of connection, and at the same time ensures smooth exhaust, thereby improving the performance of the electromagnetic diaphragm pump exhaust assembly of the present invention.

[0065] As a preferred example of the present invention, a first receiving groove 1015 is provided on the air intake plate 101, and two third connecting holes 1016 are provided on the first receiving groove 1015. The air intake component 2 is installed in the first receiving groove 1015, and two sets of air intake groups are provided on the air intake component 2. Each set of air intake groups includes multiple first air inlets 203. When the electromagnetic component 5 is working, each set of air intake groups flows to an air chamber component 3 through a third connecting hole 1016.

[0066] This setup improves the air intake structure of the electromagnetic diaphragm pump. The mechanism and working principle of the electromagnetic component 5 inside the electromagnetic diaphragm pump are the same as those of the prior art, and will not be described in detail here. A diaphragm 501 is provided at each of the opposite ends of the electromagnetic component 5. The two diaphragms 501 are used to separate the two air chamber components 3 of the pump body. Compared to the traditional single-inlet structure, this application modifies the air intake structure of the electromagnetic diaphragm pump to allow air to enter through multiple first air inlets 203 on the air intake component 2. In use, the electromagnetic component 5 drives the two diaphragms 501 to move towards the second air chamber component 3, increasing the air storage space of the first air chamber component 3 and creating a negative pressure inside the air storage chamber. Air from outside the housing 1 flows into the chamber 108 through the third connecting hole 1016 on the air intake plate 101 via the multiple first air inlets 203 on the air intake component 2, and then flows into the air storage chamber of the air chamber component 3. As the electromagnetic component 5 drives the two diaphragms 501 to move towards the side closer to the first air chamber component 3, the volume of the air storage chamber of the first air chamber component 3 decreases, and the air inside the air storage chamber of the first air chamber component 3 is finally discharged through the air outlet 4, and vice versa. By improving the structure of the air intake assembly of the electromagnetic diaphragm pump, the air intake of the electromagnetic diaphragm pump adopts a multi-entry and aggregated discharge method, which reduces the pulse-type air intake impact force of the electromagnetic diaphragm pump and improves the service life of the electromagnetic assembly 5 and the diaphragm 501.

[0067] This design reduces the flow area of ​​a single air inlet while ensuring the total air inlet flow area, preventing foreign objects from entering the chamber 108 through the air inlet and causing malfunction or component damage. At the same time, it improves the suction efficiency of the electromagnetic diaphragm pump during pumping operations and enhances the reliability of the electromagnetic diaphragm pump.

[0068] As a preferred example of the present invention, the air intake component 2 includes a first plate 201 and a flange 202. The flange 202 is disposed on the outer edge of the first plate 201 and is arranged perpendicular to the first plate 201. The first air inlet 203 is disposed on the first plate 201, and a second receiving groove 205 is formed between the first plate 201 and the flange 202.

[0069] This design discloses a structure for an air intake component 2. By forming a second receiving groove 205 between the first plate 201 and the flange 202, the air intake capacity can be increased, making it easier for the mixed air to enter the cavity 108 through the third connecting hole 1016. At the same time, the structural strength of the air intake component 2 is improved, and the structural deformation caused by vibration is reduced, which helps to improve the working performance and reliability of the electromagnetic diaphragm pump.

[0070] Preferably, a plurality of flanges 204 are provided on the outer side of the flange 202. Preferably, the outer contour section of the flange 204 is arc-shaped, which further improves the ease of assembly of the air intake 2 and the housing 1 and the stability of the connection.

[0071] As a preferred example of the present invention, the first air inlet 203 includes a recessed portion 2031 and a through portion 2032, wherein the recessed portion 2031 is disposed on the side of the first plate 201 away from the flange 202. This arrangement serves to guide the incoming airflow and also increases the air intake area of ​​the first air inlet 203, thereby helping to improve air intake efficiency and effect.

[0072] In a preferred embodiment of the present invention, the first receiving groove 1015 is formed by a recessed platform on the air intake plate 101 that extends into the cavity 108, and the first receiving groove 1015 is formed on the air intake plate 101 near the center. Preferably, the first receiving groove 1015 can be rectangular or circular. This arrangement allows the air intake plate 101 and the first receiving groove 1015 on the air intake plate 101 to be integrally formed in the housing 1, facilitating production and improving processing efficiency.

[0073] As a preferred example of the present invention, an air inlet pipe 1017 is provided on the platform corresponding to the third connecting hole 1016. The air inlet pipe 1017 is disposed inside the chamber 108 and its end abuts against the electromagnetic component 5. Specifically, an air inlet pipe 1017 is provided at each of the two third connecting holes 1016. When the electromagnetic component 5 drives the diaphragm 501 to move toward the two air chamber components 3, the air entering through the air inlet 2 enters the air chamber components 3 on both sides of the chamber 108 separately through the two third connecting holes 1016. This arrangement further ensures the reliability of air intake and the stability of operation of the electromagnetic diaphragm pump, ensuring that air enters the pump body evenly and improving the efficiency and performance of the electromagnetic diaphragm pump.

[0074] As a preferred example of the present invention, the first receiving groove 1015 is rectangular, the center line connecting the two third connecting holes 1016 is collinear with the center line of the major axis of the first receiving groove 1015, and the line connecting the first air inlets 203 on each air intake group is offset from the third connecting hole 1016. Preferably, each air intake group includes multiple first air inlets 203, and the line connecting the first air inlets 203 of each air intake group is offset from the center line connecting the two third connecting holes 1016. Preferably, each air intake group has three first air inlets 203.

[0075] This feature enhances the balanced control of gas distribution in the electromagnetic diaphragm pump's air intake assembly, increases the air intake volume, and thus improves the stability and efficiency of the electromagnetic diaphragm pump, thereby enhancing product performance.

[0076] As a preferred example of the present invention, baffles 1018 are provided on opposite sides of the air intake pipe 1017, and the length direction of the baffles 1018 is parallel to the line connecting the centers of the two third connecting holes 1016. This arrangement prevents air from escaping to both ends of the non-chamber assembly after passing through the third connecting holes 1016 and the air intake pipe 1017, while improving the structural strength of the air intake plate 101 and further enhancing the reliability of the electromagnetic diaphragm pump air intake assembly of the present invention.

[0077] As a preferred example of the present invention, a sponge is provided in the second receiving groove 205 between the first plate 201 and the air inlet plate 101.

[0078] This setting is used to filter and purify the air entering the pump body, improve the air intake quality, and reduce noise and vibration, which helps to improve the quietness of the electromagnetic diaphragm pump and enhance the user experience.

[0079] Furthermore, as a preferred example of the present invention, the air chamber assembly 3 includes an air chamber housing 301 and a cover plate 302. The cover plate 302 covers one side of the air chamber housing 301. The air chamber assembly 3 is detachably connected to the first mounting side plate 102 of the housing 1. The interior of the housing 1 forms a chamber 108 for accommodating the electromagnetic assembly 5. A first connecting nozzle 105, a positioning boss 106, and a second connecting hole 107 are provided on the first mounting side plate 102. Correspondingly, a first connecting hole 3017 is provided on the air chamber housing 301. The device includes a first connecting hole 3017 and a second connecting nozzle 3019. The first connecting nozzle 105 is inserted into and communicates with the first connecting hole 3017, and the second connecting nozzle 3019 is inserted into and communicates with the second connecting hole 107. The first connecting hole 3017 communicates with the chamber 108, and the second connecting hole 107 communicates with the gas storage box 104. The positioning boss 106 can be inserted into the connecting hole 3018 for positioning. The center lines of the first connecting hole 3017, the connecting hole 3018, and the second connecting nozzle 3019 are collinear.

[0080] This invention discloses an assembly structure for an air chamber assembly 3 and a housing 1. By improving the air outlet structure of the electromagnetic diaphragm pump, a first connecting nozzle 105, a positioning boss 106, and a second connecting hole 107 are provided on the first mounting side plate 102 of the housing 1. A first connecting hole 3017, a insertion hole 3018, and a second connecting nozzle 3019 are provided on the air chamber outer shell 301 of the air chamber assembly 3. During installation, the positioning boss 106 of the housing 1 is pre-positioned with the insertion hole 3018 on the air chamber outer shell 301, and the first connecting nozzle 105 is inserted simultaneously. The first connecting hole 3017 is connected to it, allowing the gas drawn into the chamber 108 to enter the air chamber assembly 3. The second connecting nozzle 3019 is inserted into the second connecting hole 107 and connected to it, so as to direct the gas inside the air chamber assembly 3 to the air storage box 104, ensuring reliable gas flow between the air chamber assembly and the pump body structure. At the same time, the three-point connection enables rapid positioning and assembly accuracy of the air chamber assembly 3 and the housing 1, reducing assembly errors between the air chamber assembly 3 and the housing 1, and ensuring the accuracy and stability of the assembly connection between the air chamber assembly 3 and the housing 1.

[0087] Preferably, the air chamber housing 301 further includes a second air chamber 3020. The first air chamber 3013 and the second air chamber 3020 are separated by a first partition plate 3012. The second air chamber 3020 is disposed on the side of the air chamber housing 301 near the first mounting side plate 102. An air inlet umbrella valve mounting hole 30121 is provided on the first partition plate 3012 at the position corresponding to the air inlet 30131. An air outlet umbrella valve mounting hole 30122 is provided on the first partition plate 3012 at the position corresponding to the air outlet 30132. The umbrella valves on the air inlet umbrella valve mounting hole 30121 and the air outlet umbrella valve mounting hole 30122 open in opposite directions when subjected to changes in gas pressure.

[0088] This setup, while ensuring gas connectivity, further separates the inlet and outlet air through structures such as the first partition plate 3012, the second partition plate 3014, the inlet umbrella valve mounting hole 30121, and the outlet umbrella valve mounting hole 30122. This helps to precisely control the inlet, outlet, and flow direction of the gas, improves the reliability of the electromagnetic diaphragm pump outlet assembly described in this invention, and enhances the performance of the electromagnetic diaphragm pump.

[0089] As a preferred example of this application, a limiting platform 3015 is provided in the first air chamber 3013. The plane of the limiting platform 3015 is flush with the plane of the second partition plate 3014 away from the end of the first partition plate 3012.

[0092] Specifically, during use, when the electromagnetic component 5 drives the diaphragm 501 to increase the internal space of the second air chamber 3020, the air inlet umbrella valve mounting hole 30121 on the first partition plate 3012 opens. The gas in the chamber 108 enters the air inlet 30131 of the first air chamber 3013 through the first connecting nozzle 105 and the first connecting hole 3017. The air in the air inlet 30131 passes through the air inlet umbrella valve mounting hole 30121 on the first partition plate 3012 and enters the second air chamber 3020. At this time, the air outlet umbrella valve mounting hole on the first partition plate 3012... When 30122 is in the closed state, when the electromagnetic component 5 drives the diaphragm 501 to shrink the internal space of the second air chamber 3020, the internal pressure of the second air chamber 3020 increases, the air inlet umbrella valve mounting hole 30121 on the first partition plate 3012 closes, and the air outlet umbrella valve mounting hole 30122 on the first partition plate 3012 opens under pressure. The air inside the second air chamber 3020 enters the air outlet 30132 through the air inlet umbrella valve mounting hole 30121, and then flows into the air storage box 104 for mixing through the second connecting nozzle 3019 and the second connecting hole 107.

[0093] This configuration enables the electromagnetic diaphragm pump to control and adjust different components when pumping gas, ensuring the reliability of gas flow and mixing processes, and improving the performance and reliability of the electromagnetic diaphragm pump.

[0094] As a preferred example of this application, a connecting plate 3016 is provided on the end of the housing portion 3011 away from the cover plate 302, and a plurality of screw connection holes 1011 are provided on the mounting boss 109, the connecting plate 3016 being screwed into the screw connection holes 1011 on the mounting boss 109. Specifically, one screw connection hole 1011 is provided at each of the four azimuth angles of the mounting boss 109 for detachable connection with the connecting plate 3016 on the air chamber housing 301.

[0095] This arrangement facilitates the installation, disassembly, and maintenance of the air chamber assembly 3, further improving the stability of the connection between the air chamber assembly 3 and the first mounting side plate 102 and the reliability of its operation.

The gas storage box side wall 1041 surrounds the outer surface of the mounting side plate, and the gas storage box top wall 1047 is disposed on the gas storage box side wall 1041 at one end away from the end cap 6. The gas storage box side wall 1041, the gas storage box top wall 1047, and the end cap 6 form a gas storage cavity. A first partition plate 1042 and a second partition plate 1043 are disposed within the gas storage cavity. The gas storage cavity is divided into a first gas outlet cavity 1044, a mixing cavity 1045, and a second gas outlet cavity 1046 by the first partition plate 1042 and the second partition plate 1043. The first gas outlet cavity 1044 and the second gas outlet cavity 1046 are located on opposite sides of the mixing cavity 1045 and are respectively connected to the second connecting nozzles 3019 on the two gas chamber assemblies 3. The airflow in the first gas outlet cavity 1044 and the second gas outlet cavity 1046 can flow to the mixing cavity 1045 and be discharged through the gas outlet 4.

[0097] This configuration, by separating the first air outlet chamber 1044, the second air outlet chamber 1046, and the mixing chamber 1045 within the air storage box 104 using a first partition plate 1042 and a second partition plate 1043, allows the airflow to flow and mix smoothly, further improving the continuity of the electromagnetic diaphragm pump exhaust assembly during airflow discharge and enhancing the exhaust efficiency and working performance of the electromagnetic diaphragm pump.

[0098] As a preferred example of the present invention, two second connecting holes 107 are provided on the side wall 1041 of the gas storage box, namely connecting hole one 1071 and connecting hole two 1072. The connecting hole one 1071 and connecting hole two 1072 are located on the side walls 1041 of the gas storage box on opposite sides of the top wall 1047 of the gas storage box. The connecting hole one 1071 and connecting hole two 1072 are arranged symmetrically along the plane containing the vertical center line of the gas storage box 104. The two second connecting holes 107 are connected to two second connecting nozzles 3019.

[0099] This design facilitates the integrated molding and manufacturing of the gas storage box 104 and the shell 1, while also improving the ease of assembly and airtight connection between the gas outlet on the gas chamber assembly 3 and the gas storage box 104.

[0101] This configuration ensures the reliability of gas flow from the first exhaust chamber 1044 and the second exhaust chamber 1046 to the mixing chamber 1045, while also mitigating changes in airflow speed and pressure, reducing the interference of pulse effects on airflow, and making the exhaust process more stable.

[0102] As a preferred example of the present invention, the second connecting nozzle 3019 is disposed on the side wall 1041 of the gas storage box near one end of the top wall 1047 of the gas storage box, the first through groove 10421 and the second through groove 10431 are disposed on the first partition plate 1042 and the second partition plate 1043 near one end of the end cap plate 6, and the air outlet 4 is disposed on the side wall 1041 of the gas storage box at the position of the mixing chamber 1045.

[0103] This configuration causes the airflow discharged through the air chamber assembly 3 to form a baffled flow path structure inside the air storage box 104. By changing the flow direction and speed of the airflow, the residence time of the gas in the air storage box 104 is increased, reducing the impact of the pulsed air discharge mode of the air chamber assembly 3. This makes the gas discharged by the electromagnetic diaphragm pump exhaust assembly described in the invention more uniform and stable, avoiding turbulence.

[0104] The present invention also discloses an electromagnetic diaphragm pump, wherein a side cover plate 7 is provided on the side of the end plate 6 that is back to the chamber 108 for the installation and fixing of the electromagnetic diaphragm pump.

[0105] The electromagnetic diaphragm pump of the present invention improves the air inlet structure, the air outlet structure of the air chamber assembly 3, and the structure of the air storage box 104, resulting in a compact structure, easy installation, stable connection, and strong airtightness, thus significantly improving the working performance of the electromagnetic diaphragm pump.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
