Description

Technical Field

[0001] The invention relates to the technical field of oxygen generators, in particular to a molecular sieve oxygen generator with a purification function. Background Art

[0002] Molecular sieve oxygen generator, also known as molecular sieve type oxygen generator, is an advanced oxygen production equipment, widely used in hospitals, factories, laboratories, sanatoriums, plateau military stations and stadiums and other scenarios. Its core principle is to use zeolite molecular sieve as adsorbent, through pressure swing adsorption (VPSA) technology, to separate and produce high-purity oxygen from the air. Zeolite molecular sieve is a spherical granular adsorbent processed by a special pore treatment process. Its surface and interior are covered with micropores and have selective adsorption. In the molecular sieve oxygen generator, two or more molecular sieve containers are usually used. The opening and closing of the pneumatic valve is controlled by a programmable controller, so that one container is in the adsorption process while the other container is in the desorption process, alternating between the two processes, thereby achieving continuous oxygen supply.

[0003] In the existing oxygen generator technology, most of the users are elderly people, so corresponding filters are set to achieve preliminary purification of the air, and then the purified gas is discharged through the exhaust fan to achieve the purpose of improving indoor air quality. However, although these devices have achieved certain results in air purification, there are still obvious deficiencies in the detailed processing of the purification process and the maintenance of the filter. When the air is purified through the sticky carbon filter, a large amount of dust and attachments will accumulate on the filter. These pollutants will be retained on the sticky carbon filter for a long time, which will not only reduce the purification efficiency of the filter, but also may cause secondary pollution to the air. When the sticky carbon filter is disassembled for cleaning or replacement, the fluctuations will cause the dust and attachments to fall off. Once these detached pollutants enter the interior of the equipment with the air flow, they are not only difficult to remove, but may also damage the precision parts of the equipment, and may even be discharged again through the exhaust fan, causing a negative impact on the indoor air quality.

One side of the partition 81 close to the inner side wall of the extension frame 16 is fixedly connected to the gear seat 82. The meshing transmission of the first gear 821 and the second gear 822 that are rotatably sleeved in the gear seat 82 provides a powerful power for the dynamic adjustment of the closing mechanism 8. The second gear 822 and the cam The coaxial fixed connection of 823 enables the cam 823 to rotate with the rotation of the second gear 822, and then through the transmission relationship between the first rocker arm 86 and the guide plate 85, the up and down movement of the square plate 84 is realized. When the square plate 84 moves up and down, a number of triangular plates 841 move accordingly, and the rotation sleeve of the rotating shaft and the guide plate 85 ensures the smooth and smooth movement. When the square plate 84 descends to fit tightly with the sealing seat 87, a complete sealing structure is formed, which effectively blocks the entry of outside air and impurities, ensuring the purity and stability of the internal environment of the oxygen generator. When the square plate 84 rises, the air purified by the carbon filter 162 is allowed to smoothly enter the subsequent processing flow of the oxygen generator.

[0034] See also Fig.10 - Fig.14 The driving mechanism 9 includes a driving motor 91 fixedly connected to the inner bottom end of the extension frame 16 and located inside the inner groove 83. The inner bottom end of the extension frame 16 is located inside the inner groove 83 and is symmetrically rotatably sleeved with a two-way reciprocating screw rod 92, one of which is fixedly connected to the output end of the driving motor 91. The inner bottom end and the inner top end of the extension frame 16 are both fixedly connected with a connecting seat 96. The outer wall of the connecting seat 96 is symmetrically slidably sleeved with an extension plate 93. The outer side wall of one of the connecting seats 96 is fixedly connected with a position sensor 963 connected to the main control board 19 through an electrical signal. The outer sides of the extension plate 93 are both rotatably sleeved with a third rocker arm 931. The partition 81 The inner wall is symmetrically fixedly connected with a third fixed bracket 935, and the fourth rocker arm 932 is rotatably sleeved inside several third fixed brackets 935. The other two ends of the fourth rocker arm 932 and the third rocker arm 931 are limitedly rotatably sleeved through a limit pin 933. The outer walls of the two bidirectional reciprocating screw rods 92 are symmetrically threadedly sleeved with a sleeve 921, and the sleeve 921 is fixedly connected with the first fixed bracket 922 near the center position of the extension frame 16. The outer wall of the fourth rocker arm 932 is fixedly connected with the second fixed bracket 934, and the first fixed bracket 922 and the second fixed bracket 934 are rotatably sleeved with the second rocker arm 923 that drives the fourth rocker arm 932 to move.

[0035] The above technical solution is adopted, and the power is mainly provided by the driving motor 91 fixedly connected to the inner bottom end of the extension frame 16 and located inside the inner groove 83. This design not only ensures the stable transmission of power, but also ensures that the output end of the driving motor 91 is fixedly connected to one of the two-way reciprocating screw rods 92. Through the rotation of the two-way reciprocating screw rod 92, the reciprocating movement of the sleeve 921 is realized, which not only simplifies the transmission mechanism, but also improves the transmission efficiency and stability. At the same time, the connecting seat 96, to which the inner bottom end and the inner top end of the extension frame 16 are fixedly connected, provides a stable support for the sliding of the extension plate 93, ensuring the stability and smoothness of the extension plate 93 during the movement. When 921 moves, the second rocker arm 923 rotating inside the first fixed bracket 922 and the second fixed bracket 934 pushes the fourth rocker arm 932 to rotate, thereby driving the third rocker arm 931 and the extension plate 93 to move. After the position sensor 963 detects the position of the extension plate 93, it will send a command to the main control board 19, and the main control board 19 controls the electric push rod 991 to work. The model of the position sensor 963 can be CDJ10-I2A18AN, and the position sensor 963 is located at one-fourth of the length of the connecting seat 96, which can effectively control the moving distance of the electric push rod 991. See also Figure 1 - Fig.14The end of the bidirectional reciprocating screw rod 92 connected to the output end of the driving motor 91 is fixedly sleeved with a double synchronous wheel 94, and the end of the other bidirectional reciprocating screw rod 92 is fixedly sleeved with a first single synchronous wheel 941. The outer walls of the double synchronous wheel 94 and the first single synchronous wheel 941 are sleeved with a first synchronous belt 942 for kinetic energy transmission. A clamping plate 961 is fixedly connected to the middle of the opposite side of the two connecting seats 96. The inside of the clamping plate 961 is symmetrically fixedly connected with a flexible magnetic strip 962. The two ends of the opposite side of the two third rocker arms 931 are formed into a cone shape for Separate the two flexible magnetic strips 962, the inner bottom end of the extension frame 16 is located inside the inner groove 83 and is rotatably sleeved with a sleeve rod 95, the sleeve rod 95 is located on one side of the two-way reciprocating screw rod 92, the outer wall of the sleeve rod 95 is wrapped with a dustproof cloth 951 for dust prevention, the end of the dustproof cloth 951 passes through the partition 81 and is fixedly connected to the inside of the extension plate 93, the end of the first gear 821 passes through the gear seat 82 and is fixedly connected to a fixing rod 97, the outer side wall of the partition 81 is located above the gear seat 82 and is fixedly connected to a fixing plate 99, and the end of the fixing rod 97 The second single synchronous shaft 983 is rotatably sleeved on the outer wall of the second single synchronous shaft 983 and the double synchronous wheel 94, and the second synchronous belt 943 is sleeved on the outer wall of the second single synchronous shaft 983. The other end of the second single synchronous shaft 983 is fixedly connected to an inner frame 982 rotatably sleeved on the fixed rod 97. The outer wall of the fixed rod 97 is located inside the inner frame 982 and is rotatably sleeved on the auxiliary frame 98. The auxiliary frame 98 is symmetrically slidably sleeved on the expansion block 981. The outer wall of the fixed rod 97 is provided with a spline groove 971. The outer wall of the fixed rod 97 is located at the position of the spline groove 971 and is slidably sleeved on the inner wall of the fixed rod 97. The sliding sleeve 972, the outer wall of the sliding sleeve 972 is fixedly connected to the side opposite to the two expansion blocks 981 with a fourth fixed bracket 974, the inner part of the two fourth fixed brackets 974 is rotatably sleeved with a fifth rocker arm 975 for pushing the expansion block 981 to move, the outer wall of the sliding sleeve 972 is fixedly sleeved with a limiting ring 973, the upper top of the fixed plate 99 is symmetrically fixedly connected with an electric push rod 991 connected to the electrical signal of the main control board 19, and the telescopic end of the electric push rod 991 is fixedly connected with an upper slide 992 rotatably sleeved on the outer wall of the limiting ring 973.

[0036] By adopting the above technical solution, the design of kinetic energy transmission between the double synchronous wheels 94 and the first single synchronous wheel 941 through the first synchronous belt 942 ensures the synchronous and stable rotation of the bidirectional reciprocating screw rod 92, which not only simplifies the transmission structure and reduces energy consumption, but also improves the transmission efficiency, making the movement of the extension plate 93 more stable and precise. At the same time, the flexible magnetic strips 962 symmetrically fixedly connected inside the splint 961 and the conical shape of the third rocker arm 931 cleverly realize the automatic separation and adhesion of the two flexible magnetic strips 962 during the movement of the extension plate 93, which not only enhances the sealing of the equipment, but also avoids operational errors caused by magnetic interference. The end of the dustproof cloth 951 is fixedly connected to the inside of the extension plate 93, and automatically expands or contracts with the movement of the extension plate 93, effectively blocking dust. The entry of impurities is prevented, ensuring the cleanliness and stability of the internal environment of the equipment. The connection design of the fixed rod 97 and the second single synchronous shaft 983 through the second synchronous belt 943 not only realizes the kinetic energy transmission between the first gear 821 and the double synchronous wheel 94, but also realizes the precise control of the expansion block 981 through the clever cooperation of the inner frame 982 and the auxiliary frame 98. The expansion block 981 is pushed by the fifth rocker arm 975 and can slide along the spline groove 971 of the fixed rod 97, thereby realizing the stable locking and release of the sliding sleeve 972 and the limiting collar 973. The telescopic end of the electric push rod 991 is rotatably connected with the upper slide 992, so that the user can easily control the up and down movement of the sliding sleeve 972 and the limiting collar 973 through the main control board 19, thereby realizing the locking and release operation of the expansion block 981.

[0037] Regarding the use of the equipment: the air enters the interior of the equipment through the air intake plate 161 and the extension frame 16, and the air is purified by the carbon filter 162, and the attachments in the air are adhered. After the gas enters the extension frame 16, part of the gas will enter the interior of the air filter 3 through the first air intake pipe 31, and the rest of the gas enters the interior of the equipment. The gas entering the air filter 3 will enter the interior of the negative pressure air intake muffler 4 through the second air intake pipe 41 to reduce the noise generated by the air during operation. Then the gas enters the input end of the air compressor body 5 through the exhaust end of the negative pressure air intake muffler 4 and the exhaust pipe 42. At this time, the air compressor body 5 starts to work and compresses the gas. The exhaust end of the air compressor body 5 is connected to the gas distributor 24, and the compressed gas is distributed to the two gas separation screens 21 through the distribution of the gas distributor 24. The nitrogen and oxygen are separated by the gas separation screen 21. The air is separated, wherein oxygen will enter the interior of the oxygen storage tank 22, and nitrogen will pass through the gas distributor 24 again and be discharged into the interior of the terminal sound eliminator 6. The sound generated when the nitrogen is discharged is reduced to the lowest point by the terminal sound eliminator 6 to reduce the noise generated during the discharge. The air compressor body 5 will generate a large amount of heat during operation. At this time, the two vortex radiators 26 start to work at the same time, and the discharge port of the vortex radiator 26 is located above the air compressor body 5. Therefore, the vortex radiator 26 can cool the air compressor body 5. The gas inside the equipment is driven by the exhaust fan 25. At this time, the gas inside the equipment is generated by the fluctuations generated when the exhaust fan 25 works, and the discharge end of the exhaust fan 25 is facing the wind dispersion rack 23. Therefore, the purified gas will be discharged from the interior of the equipment through the wind dispersion rack 23 and the air outlet plate 141. In this way, the air can be purified synchronously during the oxygen production process. Due to long-term use, a large amount of impurities will be attached to the outer wall of the sticky carbon filter 162. Therefore, in order to ensure the purification effect, the sticky carbon filter 162 needs to be disassembled and cleaned. During the disassembly of the air intake plate 161 and the sticky carbon filter 162, the attached objects will fall off and move greatly. Therefore, before disassembling the air intake plate 161, the user can divide the interior of the extension frame 16, and the output end of the driving motor 91 reaches the two-way reciprocating screw 92 to rotate, and the two two-way reciprocating screws 92 are driven to move synchronously through the double synchronous wheels 94, the first single synchronous wheel 941 and the first synchronous belt 942. The two ends of the two-way reciprocating screw 92 are rotatably sleeved with the sleeve 921. When the two sleeves 921 start to move synchronously, The fourth rocker arm 932 will be pushed by the first fixed bracket 922 and the second rocker arm 923, and the other end of the fourth rocker arm 932 is rotatably sleeved with the third fixed bracket 935. Therefore, when the fourth rocker arm 932 moves under the push of the second rocker arm 923, the third rocker arm 931 will be synchronously driven to perform an arc motion. After the third rocker arm 931 and the fourth rocker arm 932 perform an arc motion, a thrust will be applied to the extension plate 93, so that the extension plate 93 pulls the sleeve rod 95 to move. The two ends of the extension plate 93 are trapezoidal in shape, which can realize the pushing of the flexible magnetic strip 962. At this time, the two flexible magnetic strips 962 will no longer contact and separate. When the sleeve rod 95 is located between the two flexible magnetic strips 962, due to the lack of the end of the extension plate 93 When the extension plate 93 moves to the position of the position sensor 963, the position sensor 963 sends a command to the main control board 19, and then the main control board 19 controls the telescopic end of the electric push rod 991 to drive the upper slide 992 to move up and down. The upper slide 992 is located in the outer wall of the limiting collar 973, so the limiting collar 973 and the sleeve 972 will be pushed to slide at the position of the spline groove 971 on the outer wall of the fixed rod 97, and the outer wall of the sleeve 972 is provided with a fourth fixed bracket 974 and a fifth rocker arm 975. By sliding the sleeve 972 up and down, the fifth rocker arm 975 can be used to adjust the position of the expansion block 981 inside the auxiliary frame 98. At this time, the outer wall of the expansion block 981 contacts the inside of the inner frame 982, and as the friction force increases, the sleeve 972 rotates, and the fixed rod 97 is synchronously driven to rotate, and the second single synchronous shaft 983 rotates through the second synchronous belt 943 and the double synchronous wheel 94. Therefore, when the fixed rod 97 rotates, it will drive the first gear 821 and the second gear 822 to engage and transmit, thereby driving the cam 823 to perform an arc motion, and the arc motion of the cam 823 drives the position adjustment of the first rocker arm 86 and the guide plate 85, and further drives the plurality of square plates 84 to flip through the connection between the guide plate 85 and the rotating shaft of the triangular plate 841, so that they can fit each other, thereby forming a closed state.In this way, the interior of the extension frame 16 can be stably partitioned, and no auxiliary objects will enter the interior of the device during the removal of the air intake plate 161 and the carbon-adhesive filter 162. Before the user puts the air intake plate 161 back in, the interior of the extension frame 16 needs to be cleaned to avoid attachments and impurities.
