Technical Field
[0001] This invention belongs to the field of disinfection cabinet technology and relates to a steam disinfection cabinet. Background Technology
[0002] A steam sterilizer is a device that uses high-temperature steam for sterilization and disinfection. It plays an important role in fields such as medical care, catering, pharmaceuticals, and biomedical engineering.
[0003] As the core component of a steam sterilizer, the steam generator's normal operation directly affects the sterilization effect. To ensure sterilization efficiency and coverage, some steam sterilizers are equipped with multiple steam generators, which are usually compactly arranged inside the sterilizer. Currently, steam generators are mostly installed in a fixed manner. When a steam generator malfunctions and needs repair or replacement, the limited space between multiple steam generators and between the steam generator and surrounding components makes it difficult for operators to access the internal parts. Sometimes, it is necessary to disassemble other surrounding components before performing repair work, which not only increases the difficulty of repair, prolongs the repair time, and reduces maintenance efficiency, but may also cause accidental damage to surrounding components during disassembly, increasing maintenance costs.
[0004] To address the above problems, this invention proposes a steam sterilization cabinet. Summary of the Invention
[0005] To address the problems existing in the background art, the present invention proposes a steam sterilization cabinet.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A steam sterilizer includes a cabinet body with a steam chamber at its lower part. An installation unit for mounting a steam generator is disposed within the steam chamber. The installation unit includes a sliding seat, a first push plate, and a second push plate. The sliding seat is slidably disposed within the steam chamber. The first push plate is vertically movable on the sliding seat, and the second push plate is horizontally slidably disposed on the sliding seat. A steam generator is mounted on both the first and second push plates. A guide portion is provided on the side wall of the steam chamber, with one end of the guide portion near the steam chamber outlet inclined outwards. The second push plate is slidably engaged with the guide portion via a connector. A linkage is provided between the first and second push plates; when the second push plate moves away from the first push plate, the first push plate moves upwards. A blocking component is installed on the cabinet body to block the opening of the steam chamber; when the blocking component is opened, the sliding seat moves outwards.
[0007] Furthermore, one end of the steam generator on the second push plate is rotatably mounted on the corresponding second push plate, and the steam generator on the second push plate is fixedly connected to a gear, the gear meshing with a rack, and the rack being fixed on a sliding seat.
[0008] Furthermore, the shielding assembly includes a plurality of connecting blocks that are hinged in sequence, and guide posts are connected to both sides of each connecting block. A first limiting groove is provided on the inner wall of the steam chamber to slide with the guide posts. The first limiting groove includes a vertical section and a horizontal section, and the vertical section and the horizontal section are connected.
[0009] Furthermore, a drive rod for driving the shielding assembly is rotatably installed inside the steam chamber. A connecting block at one end of the shielding assembly is connected to a fixing block, and the fixing block is slidably sleeved on the drive rod. A spiral groove is provided on the drive rod, and a second guide block is slidably disposed in the spiral groove. The fixing block is connected to the second guide block. A threaded rod that drives the sliding seat is rotatably installed inside the steam chamber, and a belt drive assembly connects the drive rod and the threaded rod.
[0010] Furthermore, the spiral groove includes a first spiral segment and a second spiral segment, which are connected; the first spiral segment is located on the side of the drive rod near the opening of the steam chamber; the pitch of the first spiral segment is greater than the pitch of the second spiral segment.
[0011] Furthermore, the guide portion includes a second limiting groove and an inclined groove; the second limiting groove is horizontally arranged, one end of the inclined groove is connected to the end of the second limiting groove near the opening, and the other end of the inclined groove is inclined outward.
[0012] Furthermore, the connector includes a connecting rod and a first guide block; the connecting rod is fixedly connected to the second push plate, and the first guide block is slidably disposed within the guide portion and connected to the connecting rod.
[0013] Furthermore, the linkage includes a connecting rod and a fixed plate; the first push plate is fixedly connected to a guide rod, which slides vertically through the sliding seat; the fixed plate is fixed to the lower end of the guide rod; each second push plate is hinged to a connecting rod, with the end of the connecting rod away from the second push plate hinged to the fixed plate.
[0014] Furthermore, the inner wall of the cabinet is provided with multiple slots for mounting trays.
[0015] Furthermore, the cabinet is equipped with a collection box for collecting condensate.
[0016] Compared with the prior art, the present invention has the following beneficial effects: When the shielding assembly is opened, the sliding seat drives the steam generator to move outward, facilitating maintenance of the steam generator. Furthermore, when the sliding seat moves outside the steam chamber, the second push plate moves away from the first push plate, increasing the distance between adjacent steam generators and thus increasing the maintenance space, facilitating maintenance operations. Simultaneously, the first push plate moves upward, making the central steam generator higher than the steam generators on both sides, further increasing the maintenance space. When the second push plate moves away from the first push plate, one end of the steam generators on both sides flips outward, further increasing the operating space and improving maintenance efficiency.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] like Figures 1-12 As shown, the technical solution adopted by the present invention is as follows: A steam sterilization cabinet includes a cabinet body 1, an installation unit and a steam generator 11.
[0021] The cabinet 1 is equipped with a cabinet door 2, which has a transparent observation window 3 for viewing the interior of the cabinet 1. Multiple slots 5 are provided on the inner wall of the cabinet 1, and the end of a tray 6 is slidably inserted into one of these slots. The tray 6 is slidably installed inside the cabinet 1 via the slots 5. The tray 6 is used to place items to be disinfected.
[0022] A collection box 7 is installed at the bottom of cabinet 1 to collect condensate produced after disinfection.
[0023] A steam chamber 8 is provided at the bottom of the cabinet 1, and the steam chamber 8 is located below the collection box 7.
[0024] The cabinet 1 is equipped with a shielding assembly that blocks the opening of the steam chamber 8. The shielding assembly includes multiple connecting blocks 4 that are hinged together in sequence. Each connecting block 4 has guide posts connected to both ends. A first limiting groove 15 is formed on the inner wall of the steam chamber 8, which slides within the guide posts. The guide posts are slidably disposed within the first limiting groove 15. The first limiting groove 15 includes a vertical section and a horizontal section, which are connected. When the shielding assembly is in the vertical section of the first limiting groove 15, the shielding assembly blocks the opening of the steam chamber 8. When the shielding assembly is in the horizontal section, the steam chamber 8 is open.
[0025] A fixing block 13 is fixedly connected to a connecting block 4 at one end of the shielding component. A drive rod 12 is rotatably installed inside the steam chamber 8, and the fixing block 13 is slidably sleeved on the drive rod 12. A spiral groove is opened on the drive rod 12, and a second guide block 27 is connected to the fixing block 13. The second guide block 27 is slidably disposed in the spiral groove. A motor 28 for driving the drive rod 12 to rotate is fixedly installed on the cabinet 1.
[0026] The mounting unit is installed inside the steam chamber 8, and the steam generator 11 is mounted on the mounting unit. The mounting unit includes a sliding seat 10, a first push plate 9, and a second push plate 19.
[0027] The sliding seat 10 is slidably disposed inside the cabinet 1. Specifically, two sliding grooves are symmetrically opened on the inner wall of the steam chamber 8, and the end of the sliding seat 10 is slidably disposed in the sliding groove.
[0028] A threaded rod 14 is rotatably mounted inside the steam chamber 8, and a nut 24 is threaded onto the threaded rod 14. The sliding seat 10 is fixedly connected to the nut 24. The threaded rod 14 and the drive rod 12 are arranged parallel to each other, and the helical direction of the spiral groove on the drive rod 12 is opposite to the helical direction of the thread on the threaded rod 14. The threaded rod 14 and the drive rod 12 are connected by a belt drive assembly 18. Specifically, the belt drive assembly 18 includes two pulleys and a drive belt. The two pulleys are respectively mounted on the drive rod 12 and the threaded rod 14, and the drive belt is wound between the drive rod 12 and the threaded rod 14.
[0029] The drive rod 12 rotates, causing the fixed block 13 to move away from the opening of the steam chamber 8, thereby moving one end of the shielding assembly into the steam chamber 8 and opening the steam chamber 8. At the same time, the threaded rod 14 rotates, causing the sliding seat 10 to move along the sliding groove, moving the sliding seat 10 to the outside of the steam chamber 8 to facilitate maintenance of the steam generator 11.
[0030] The helical groove on the drive rod 12 includes a first helical segment and a second helical segment. The first helical segment and the second helical segment are connected. The pitch of the first helical segment is greater than the pitch of the second helical segment. The first helical segment is close to the opening of the steam chamber 8. When the blocking assembly blocks the opening of the steam chamber 8, the fixing block 13 is located at the end of the first helical segment away from the second helical segment. When the drive rod 12 rotates, the fixing block 13 moves rapidly along the drive rod 12 towards the second helical segment. The blocking assembly can move rapidly to open the steam chamber 8, allowing the sliding seat 10 to move outside the steam chamber 8.
[0031] In this embodiment, the first push plate 9 is vertically movable and disposed in the middle of the sliding seat 10, and a second push plate 19 is disposed on both sides of the first push plate 9. A steam generator 11 is mounted on both the first push plate 9 and the second push plate 19. The second push plate 19 is horizontally slidably disposed on the sliding seat 10. Guide portions are disposed on the inner walls of both sides of the steam chamber 8, with the end of the guide portion near the outlet of the steam chamber 8 inclined outwards. The second push plate 19 slides along the guide portion on the same side via a connecting member.
[0032] The guide section includes a second limiting groove 25 and an inclined groove 26. The second limiting groove 25 is horizontally arranged, one end of the inclined groove 26 is connected to the end of the second limiting groove 25 near the opening, and the other end of the inclined groove 26 is inclined outward. The connecting member includes a connecting rod 22 and a first guide block 23. The connecting rod 22 is fixedly connected to the second push plate 19, and the first guide block 23 is slidably arranged in the guide section and connected to the connecting rod 22.
[0033] When the sliding seat 10 moves outward, the first push plate 9 and the second push plate 19 move outward accordingly. The second push plate 19 moves outward along the guide portion through the connector. When the first guide block 23 moves into the inclined groove 26, the second push plate 19 moves outward and moves away from the first push plate 9.
[0034] The first push plate 9 is fixedly connected to a guide rod 29. The guide rod 29 slides vertically through the sliding seat 10. A linkage is provided between the first push plate 9 and the second push plate 19. When the second push plate 19 moves away from the first push plate 9, the first push plate 9 moves upward under the action of the linkage.
[0035] Specifically, the linkage includes a connecting rod 17 and a fixed plate 16. The fixed plate 16 is fixed to the lower end of the guide rod 29. Connecting rods 17 are hinged to both ends of the fixed plate 16. The two connecting rods 17 correspond one-to-one with the two second push plates 19, and the end of the connecting rod 17 away from the fixed plate 16 is hinged to the corresponding second push plate 19.
[0036] One end of the steam generator 11 on the second push plate 19 is rotatably mounted on the second push plate 19. A gear 20 is fixedly mounted on the steam generator 11 on the second push plate 19, and the gear 20 meshes with a rack 21, which is fixed to the sliding seat 10. When the second push plate 19 drives the corresponding steam generator 11 to move away from the first push plate 9, the gear 20 rotates under the action of the rack 21, thereby causing one end of the steam generator 11 on the second push plate 19 to deflect outward. This further increases the distance between adjacent steam generators 11, further expands the maintenance space, and further facilitates maintenance.
[0037] Working principle: When in use, start the steam generator 11 in the steam chamber 8. The high temperature steam generated by the steam generator 11 enters the top of the cabinet 1 and disinfects the items on the tray 6.
[0038] When the steam generator 11 in the steam chamber 8 needs maintenance, the motor 28 is started. The motor 28 drives the drive rod 12 to rotate, causing the fixed block 13 to move away from the opening of the steam chamber 8. The fixed block 13 drives the shielding assembly line to move, and the guide column slides along the first limiting groove 15, thereby opening the opening.
[0039] Simultaneously, the drive rod 12 drives the threaded rod 14 to rotate via the belt drive assembly 18, causing the sliding seat 10 to move out of the steam chamber 8. Due to the large pitch of the first helical segment, the fixing block 13 moves quickly, thereby causing the opening to open rapidly, allowing the sliding seat 10 to move out of the steam chamber 8. After the opening is opened, the fixing block 13 engages with the second threaded segment, and the blocking assembly slides slowly along the threaded rod 14.
[0040] The sliding seat 10 drives the first push plate 9 and the second push plate 19 to move outward simultaneously. The first guide block 23 slides along the second limiting groove 25. When the first guide block 23 moves into the inclined groove 26, under the guidance of the inclined groove 26, the first guide block 23 pulls the second push plate 19 outward through the connecting rod 22 and moves away from the first push plate 9. This increases the distance between adjacent steam generators 11, making it easier to repair the steam generators 11.
[0041] When the second push plate 19 moves away from the first push plate 9, the second push plate 19 drives the fixed plate 16 to move upward through the connecting rod 17, and the first push plate 9 moves upward. This causes the steam generator 11 on the first push plate 9 and the steam generator 11 on the second push plate 19 to be vertically offset, further increasing the maintenance space and making maintenance more convenient.
[0042] Furthermore, when the second push plate 19 drives the corresponding steam generator 11 to move away from the first push plate 9, the gear 20 rotates under the action of the rack 21, thereby causing one end of the steam generator 11 on the second push plate 19 to deflect outward. This further increases the distance between adjacent steam generators 11, further expands the maintenance space, and further facilitates maintenance.
[0043] After maintenance, the motor 28 is started, and the drive rod 12 rotates, causing the fixed block 13 to move closer to the opening, which in turn causes the blocking assembly to move towards the opening and block it. At the same time, the threaded rod 14 rotates, causing the sliding seat 10 to move into the steam chamber 8. As the first guide block 23 slides along the inclined groove 26, the second push plate 19 moves closer to the first push plate 9.
[0044] When the second push plate 19 moves closer to the first push plate 9, the first push plate 9 is pushed downward by the connecting rod 17.
[0045] Furthermore, when the second push plate 19 moves closer to the first push plate 9, the gear 20 rotates under the action of the rack 21, and the steam generator 11 on the second push plate 19 rotates towards the first push plate 9.
[0046] Then, the sliding seat 10 continues to move into the steam chamber 8. Finally, the sliding seat 10 returns to the steam chamber 8, and the blocking assembly blocks the opening.
[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
