Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a piston compressor for a household oxygen generator. Background Technique

[0002] The PSA (Pressure Swing Absorption) oxygen generation device separates gas mixtures by utilizing the difference in the adsorption performance of molecular sieves for different gas molecules. It uses air as the raw material and separates nitrogen and oxygen in the air by using the selective adsorption performance of a high-efficiency and high-selectivity solid adsorbent for nitrogen and oxygen. Under normal temperature and pressure conditions, PSA special molecular sieves are used to selectively adsorb impurities such as nitrogen, carbon dioxide, and water in the air to obtain oxygen.

[0003] The VPSA (Vacuum Pressure Swing Adsorption) oxygen generation device is a relatively novel oxygen generation method, which has obvious advantages in flexible and variable oxygen usage occasions. It inhales nitrogen and oxygen in the air under low-pressure conditions, and after the molecular sieve is saturated with adsorption, it desorbs under vacuum conditions, discharges nitrogen from the discharge port, and oxygen enters the purification system. The molecular sieve continuously adsorbs and decompresses to cycle and produce high-purity oxygen.

[0004] When the existing four-cylinder piston compressor is used in a PSA or VPSA system, in order to meet the simultaneous positive-pressure operation of four cylinders or the operation of two cylinders with positive pressure and two cylinders with negative pressure, a relatively complex air passage structure generally needs to be set, and the air passage structures in the two system modes are different, having the disadvantages of large processing difficulty and low standardization degree. Content of the Utility Model

[0005] To solve the problems in the background technique, the utility model provides a piston compressor for a household oxygen generator, including a cylinder block assembly and a switching valve body assembly. The cylinder block assembly includes a main frame body, a top cover, and a valve plate, and the switching valve body assembly includes an adjusting bolt and a valve cover;

[0006] The top cover and the main frame are fixedly connected up and down. Four groups of cylinder barrels distributed in a cross shape are installed inside the main frame and the top cover. An upper horizontal air duct is provided inside the top cover. The two ends of the main body of the top cover are provided with a first upper through hole and a second upper through hole communicating with the upper horizontal air duct. A lower horizontal air duct is provided inside the main frame. The two ends of the main body of the main frame are provided with a first lower through hole and a second lower through hole communicating with the lower horizontal air duct. The valve plate is located at the outer end of the cylinder barrel, and one-way air inlet holes and air outlet holes are respectively provided on both sides of the main body of the valve plate. A cylinder head is hermetically connected to the outer side of the main body of the valve plate. An air cavity is symmetrically provided inside the cylinder head. Air outlet connection holes and air inlet connection holes are respectively provided at the diagonal corners of the valve plate, and the air outlet connection hole is connected to the one-way air outlet hole provided on one side of the main body of the valve plate, and the air inlet connection hole is connected to the one-way air inlet hole provided on the other side of the main body of the valve plate. By flipping the valve plate up and down, the air outlet connection holes and air inlet connection holes provided at the diagonal corners of each group of valve plates can be connected to the upper horizontal air duct or the lower horizontal air duct;

[0007] Pairs of switching valve shells are connected in both the upper horizontal air duct and the lower horizontal air duct. An elastic downward valve core is hermetically slidably connected inside each group of switching valve shells. The valve cover is connected to the outer opening of the switching valve shell. The adjusting bolt is threadedly connected to the valve cover, and the inner end of the adjusting bolt is screwed to the outer end of the valve core.

[0008] The technical solution of the present utility model is used as follows:

[0009] By connecting the air outlet connection holes and air inlet connection holes at the diagonal corners of the valve plate to the upper horizontal air duct or the lower horizontal air duct respectively, and cooperating with the opening and closing action of the valve core, the four groups of cylinder barrels of the piston compressor can all be under positive pressure, or two groups of cylinder barrels are under positive pressure and two groups of cylinder barrels are under negative pressure;

[0010] When the four groups of cylinder barrels are under positive pressure, the oxygen generator is a PSA system at this time. At this time, all four groups of valve cores are opened, the air outlet connection holes in all four groups of valve plates are connected to the upper horizontal air duct, and the air inlet connection holes are all connected to the lower horizontal air duct;

[0011] And at this time, both the first upper through hole and the second upper through hole are for air outlet, both the first lower through hole and the second lower through hole are for air inlet, and the compressed air formed by the four groups of cylinder barrels can be discharged from the first upper through hole and the second upper through hole;

[0012] When two groups of cylinder barrels are under positive pressure and two groups of cylinder barrels are under negative pressure, the oxygen generator is a VPSA system at this time;

[0013] And at this time, the first upper through hole and the second upper through hole provided at both ends of the top cover are one for air inlet and one for air outlet, and the first lower through hole and the second lower through hole provided at both ends of the main frame are one for air inlet and one for air outlet;

[0014] And at this time, all four groups of valve cores are closed;

[0015] Moreover, two sets of valve cores in the upper horizontal air duct and the lower horizontal air duct respectively isolate the upper horizontal air duct and the lower horizontal air duct into a positive-pressure air duct and a negative-pressure air duct. The air outlet connection holes in two adjacent sets of valve plates can be communicated with the positive-pressure air duct formed by isolating the upper horizontal air duct by the valve core, and the air inlet connection holes can be communicated with the negative-pressure air duct formed by isolating the lower horizontal air duct by the valve core. At the same time, the air inlet connection holes in the other two adjacent sets of valve plates are communicated with the negative-pressure air duct formed by isolating the upper horizontal air duct by the valve core, and the air outlet connection holes are communicated with the positive-pressure air duct formed by isolating the lower horizontal air duct.

[0016] At this time, two adjacent sets of cylinders are used as positive pressure, and the other two sets of cylinders are used as negative pressure.

[0017] By adopting the above technical solution, the following beneficial effects can be achieved by the present utility model:

[0018] (1) Based on the detachable top cover and the main frame body, the present utility model installs four sets of cylinders distributed in a cross shape in the cavity structure formed by the top cover and the main frame body, which can form the basis for the simultaneous operation of the four sets of cylinders.

[0019] (2) Moreover, the present utility model also respectively opens an upper horizontal air duct and a lower horizontal air duct in the horizontal direction in the main bodies of the top cover and the main frame body. The purpose of horizontally opening the upper horizontal air duct and the lower horizontal air duct is not only to realize the connection with all cylinders through the air outlet connection holes and air inlet connection holes diagonally opened on the valve plates, but also to improve the air inlet and outlet efficiency through the horizontal opening of the upper horizontal air duct and the lower horizontal air duct.

[0020] (3) The present utility model also pairs of switching valve body assemblies are provided in the main bodies of the top cover and the main frame body. By opening and closing the valve cores and cooperating with the connection of the air outlet connection holes and air inlet connection holes in different valve plates with the upper horizontal air duct or the lower horizontal air duct, the piston compressor can form a mode in which all four sets of cylinders are positive pressure, or a mode in which two sets of cylinders are positive pressure and two sets of cylinders are negative pressure, which is suitable for both the PSA system of the oxygen generator and the VPSA system of the oxygen generator.

[0034] The following refers to Figures 1-9 An embodiment of a piston compressor for a household oxygen generator provided by the present utility model will be described;

[0035] The top cover 102 of the cylinder block assembly 1 and the main frame body 101 are fixedly connected up and down, jointly forming the inner cavity framework of the compressor. Four groups of cylinder barrels 103 distributed in a cross shape are installed in the main frame body 101 and the top cover 102. An upper horizontal air passage 117 is provided in the top cover 102. The two ends of the main body of the top cover 102 are provided with an upper first through hole 118 and an upper second through hole 119 communicating with the upper horizontal air passage 117. A lower horizontal air passage 121 is provided in the main frame body 101. The two ends of the main body of the main frame body 101 are provided with a lower first through hole 122 and a lower second through hole 123 communicating with the lower horizontal air passage 121. The valve plate 104 is located at the outer end of the cylinder barrel 103, and one-way air inlet holes and air outlet holes are respectively provided on both sides of the main body of the valve plate 104. The outer side of the main body of the valve plate 104 is also hermetically covered with a cylinder head 107. Air cavities 114 are symmetrically provided inside the cylinder head 107, which can form an air inlet cavity and an air outlet cavity. Air outlet connection holes 115 and air inlet connection holes 116 are respectively provided at the diagonal corners of the valve plate 104, and the air outlet connection hole 115 is connected to the one-way air outlet hole provided on one side of the main body of the valve plate 104, and the air inlet connection hole 116 is connected to the one-way air inlet hole provided on the other side of the main body of the valve plate 104. By flipping the valve plate 104 up and down, the air outlet connection holes 115 and air inlet connection holes 116 provided at the diagonal corners of each group of valve plates 104 can be connected to the upper horizontal air passage 117 or the lower horizontal air passage 121;

[0036] Pairs of switching valve housings 201 are connected in the upper horizontal air passage 117 and the lower horizontal air passage 121. An elastically downward valve core 202 is hermetically slidably connected inside each group of switching valve housings 201. A valve cover 204 is covered at the outer end opening of the switching valve housing 201. An adjusting bolt 203 is threadedly connected in the valve cover 204, and the inner end of the adjusting bolt 203 is screwed to the outer end of the valve core 202. Through the opening and closing action formed by the valve core 202, the through holes at both ends of the upper horizontal air passage 117 or the lower horizontal air passage 121 can be connected or disconnected.

[0037] The working principle is as follows:

[0038] By connecting the air outlet connection holes 115 and the air inlet connection holes 116 at the diagonals of the valve plate 104 to the upper horizontal air duct 117 or the lower horizontal air duct 121 respectively, and cooperating with the opening and closing action of the valve core 202, the four groups of cylinder barrels 103 of the piston compressor can all be under positive pressure, or two groups of cylinder barrels 103 are under positive pressure and two groups of cylinder barrels 103 are under negative pressure;

[0039] When the four groups of cylinder barrels 103 are under positive pressure, the oxygen generator is in the PSA system at this time. At this time, all four groups of valve cores 202 are opened, the air outlet connection holes 115 in all four groups of valve plates 104 are connected to the upper horizontal air duct 117, and the air inlet connection holes 116 are all connected to the lower horizontal air duct 121;

[0040] And at this time, both the upper first through hole 118 and the upper second through hole 119 are for air outlet, and both the lower first through hole 122 and the lower second through hole 123 are for air inlet. The compressed air formed by the four groups of cylinder barrels 103 can be discharged from the upper first through hole 118 and the upper second through hole 119;

[0041] When two groups of cylinder barrels 103 are under positive pressure and two groups of cylinder barrels 103 are under negative pressure, the oxygen generator is in the VPSA system at this time;

[0042] And at this time, the upper first through hole 118 and the upper second through hole 119 opened at both ends of the top cover 102 are one for air inlet and one for air outlet, and the lower first through hole 122 and the lower second through hole 123 opened at both ends of the main frame body 101 are one for air inlet and one for air outlet;

[0043] And at this time, all four groups of valve cores 202 are closed;

[0044] Moreover, the two groups of valve cores 202 in the upper horizontal air duct 117 and the lower horizontal air duct 121 respectively isolate the upper horizontal air duct 117 and the lower horizontal air duct 121 into a positive pressure air duct and a negative pressure air duct. The air outlet connection holes 115 in the adjacent two groups of valve plates 104 can be connected to the positive pressure air duct formed by the isolation of the valve core 202 in the upper horizontal air duct 117, and the air inlet connection holes 116 are connected to the negative pressure air duct formed by the isolation of the valve core 202 in the lower horizontal air duct 121; at the same time, the air inlet connection holes 116 in the other adjacent two groups of valve plates 104 are connected to the negative pressure air duct formed by the isolation of the valve core 202 in the upper horizontal air duct 117, and the air outlet connection holes 115 are connected to the positive pressure air duct formed by the isolation in the lower horizontal air duct 121;

[0045] At this time, the adjacent two groups of cylinder barrels 103 are used as positive pressure, and the other two groups of cylinder barrels 103 are used as negative pressure, which is suitable for both the PSA system of the oxygen generator and the VPSA system of the oxygen generator.

[0046] The specific structure of the cylinder block assembly 1 is as Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in Figure 7 , the intake valve hole 105 is opened on the outer side of one side of the main body of the valve plate 104. An exhaust valve piece 106 is installed on the outer side of the other side of the main body of the valve plate 104. An intake valve piece 112 is installed at a position on the inner side of one side of the main body of the valve plate 104 opposite to the intake valve hole 105. An exhaust valve hole 113 is opened at a position on the inner side of the other side of the main body of the valve plate 104 opposite to the exhaust valve piece 106;

[0047] By installing the intake valve piece 112 on one side of the intake valve hole 105 and the exhaust valve piece 106 on one side of the exhaust valve hole 113, only allows gas to flow from the intake connection hole 116 to the intake valve hole 105, and only allows gas to flow from the exhaust valve hole 113 to the exhaust connection hole 115;

[0048] Both ends of the main body of the main shaft 108 are fixedly installed with rotary joints 109. The main shaft 108 is rotationally connected to the middle of the cavity formed by the top cover 102 and the main frame 101 through the rotary joints 109 at both ends;

[0049] The inner end of the crank 110 is rotationally connected to the main shaft 108 through an eccentric shaft 124. A piston cover 111 is installed at the outer end of each group of cranks 110, and the piston covers 111 facing each other on the same side are slidably connected in the cylinder barrel 103 in a sealed manner, so that under the drive of the rotation of the main shaft 108, the piston cover 111 at the outer end of each group of cranks 110 can reciprocate in the corresponding cylinder barrel 103;

[0050] Both ends of the main shaft 108 are also fixed with balance weights 125, the purpose of which is to increase the rotational inertia of the cylinder barrel 103 and reduce the rotational vibration and noise of the cylinder barrel 103;

[0051] And a pressure relief hole 120 is also opened at the other end of the main body of the top cover 102 for pressure relief operation when the pressure is too high.

[0052] The specific structure of the switching valve body assembly 2 is as Figure 8 shown. The threaded rotary seat 205 is fixedly installed in the middle of the main body of the valve cover 204. The adjusting bolt 203 is threadedly connected to the threaded rotary seat 205;

[0053] An inner pressure spring 206 is also sleeved and installed in the adjusting bolt 203. One end of the inner pressure spring 206 is clamped on the inner surface of the valve cover 204, and the other end of the inner pressure spring 206 is clamped on the outer surface of the valve core 202;

[0054] By screwing the adjusting bolt 203 located outside the valve cover 204, the valve core 202 can be driven to move. Through the vertical movement of the valve core 202 distributed in pairs in the main body of the upper horizontal air duct 117 or the lower horizontal air duct 121, the purpose of isolating the upper horizontal air duct 117 or the lower horizontal air duct 121 can be achieved, so that in the states of positive pressure of the two groups of cylinder barrels 103 and negative pressure of the two groups of cylinder barrels 103, the positive and negative pressure channels in the upper horizontal air duct 117 or the lower horizontal air duct 121 are completely isolated and will not affect each other;

[0055] Moreover, through the elastic top force of the inner pressure spring 206 on the valve core 202, a certain position holding effect can be formed on the adjusted state of the valve core 202, thereby improving the safety effect of the opening and closing state of the valve core 202.

[0056] The specific structure of the driving member 3 is as Figure 9 shown. The outer top end of the rotating motor 301 is fixedly connected to the outer bottom of the main frame body 101, and there is enough space between the outer top end of the rotating motor 301 and the outer bottom of the main frame body 101 to provide space for the switching valve body assembly 2 installed in the main frame body 101;

[0057] The low end of the main shaft 108 is fixedly connected to the rotating shaft of the rotating motor 301;

[0058] Connecting frames 302 are installed on both outer sides of the rotating motor 301. Both sides of the bottom end of each group of connecting frames 302 are connected with shock-absorbing springs 303, and the shock-absorbing springs 303 are used to eliminate noise and vibration after being connected to the external shell.

[0059] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
