Description

Technical Field

[0001] This application relates to the technical field of medical device drying, and more particularly to a vacuum drying apparatus for medical devices. Background Technology

[0002] A vacuum drying device is a drying apparatus that places the material to be dried in a negative pressure environment. It mainly includes a drying chamber, a vacuum pump, and a heating element. The vacuum pump, connected to the drying chamber, extracts gas from the chamber, creating a vacuum environment and lowering the vaporization temperature of water droplets adhering to the material. The heating element, located in the drying chamber, heats the material, causing the water droplets to fully vaporize. Then, the vacuum pump removes the vaporized water vapor, achieving the drying process.

[0003] In related technologies, traditional vacuum drying devices are generally configured as a large-space drying chamber, with a vacuum pump and a heating element installed in this chamber to achieve simultaneous drying of large quantities of materials. However, when the amount of material to be dried is small, the vacuum pump still needs to evacuate the entire drying chamber, and the heating element still needs to provide heat to the entire drying chamber. This results in long start-up times, high energy consumption, and severely affects the drying efficiency of the device. Utility Model Content

[0004] This application provides a vacuum drying device for medical devices to solve the technical problems of high energy consumption and low drying efficiency of traditional vacuum drying devices.

[0005] Therefore, this application provides a vacuum drying device for medical devices, comprising: a housing including at least two drying chambers; a switching assembly disposed between two adjacent drying chambers, the switching assembly being movable to open and connect the two adjacent drying chambers or close and isolate the two adjacent drying chambers; a vacuum assembly connected to the drying chambers for removing gas from the drying chambers; and a heating assembly disposed in the housing for providing a heat source to the drying chambers.

[0006] In one possible implementation, a through connection window is provided between two adjacent drying chambers. The switching assembly includes a torsion spring, a closing plate, and a locking member. The closing plate is rotatably connected to the drying chamber via the torsion spring, and the locking member is used to lock the closing plate when it is closed on the connection window.

[0007] In one possible implementation, the switch assembly further includes a sealing gasket disposed on the side of the opening plate facing the connection window.

[0008] In one possible implementation, the sealing gasket is a sealing ring, the size of which is greater than or equal to the size of the connecting window, and can be placed around the outer periphery of the connecting window when the opening and closing plate is closed on the connecting window.

[0009] In one possible implementation, a control unit is also included, disposed in the housing, and the control unit is electrically connected to the switching assembly, the vacuum assembly, and the heating assembly, respectively.

[0010] In one possible implementation, the vacuum assembly includes a vacuum pump, a vacuum main pipe, at least two vacuum branch pipes, and at least two control valves. One end of each vacuum branch pipe is connected to the drying chamber, and the other end is connected to the vacuum pump via the vacuum main pipe. At least one control valve is provided on each vacuum branch pipe, and the control valve is electrically connected to a control component.

[0011] In one possible implementation, the heating assembly includes at least two heating elements arranged around the peripheral sidewall of the drying chamber, and the heating elements are electrically connected to the control unit.

[0012] In one possible implementation, a heat insulation element is also included, which is disposed on the inner peripheral wall of the drying chamber.

[0013] A vacuum drying device for medical devices according to an embodiment of this application includes: a housing comprising at least two drying chambers; a switching assembly disposed between two adjacent drying chambers, the switching assembly being movable to open and connect the two adjacent drying chambers or close and isolate the two adjacent drying chambers; a vacuum assembly connected to the drying chambers for removing gas from the drying chambers; and a heating assembly disposed in the housing for providing a heat source to the drying chambers. This technical solution provides at least two drying chambers within the housing and a switching assembly between two adjacent drying chambers, allowing the movement of the switching assembly to control the connection or isolation of the two adjacent drying chambers. This allows users to selectively use one drying chamber to dry a small batch of materials, shortening start-up time, reducing energy consumption, and improving drying efficiency; or to simultaneously use multiple drying chambers to achieve simultaneous drying of a large batch of materials, shortening waiting time and improving drying efficiency. Specifically, when one drying chamber is used, the switching component is in the off state, isolating the two adjacent drying chambers. In this case, the vacuum and heating components operate only on the designated drying chamber, providing it with negative pressure and a thermal environment. Due to the smaller overall space of this drying chamber, the evacuation and heating times are short, resulting in a short start-up time from ambient temperature to drying temperature, low energy consumption, high drying efficiency, and good drying effect. When at least two drying chambers are required, the switching component is in the on state, connecting the two adjacent drying chambers. In this case, the vacuum and heating components operate on multiple drying chambers, providing negative pressure and a thermal environment to all of them. This allows for the simultaneous drying of large batches of materials, resulting in short drying time and high drying efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] See Figure 1 and Figure 2 A vacuum drying apparatus for medical devices includes: a housing 100 including at least two drying chambers 101; a switching assembly 200 disposed between two adjacent drying chambers 101, the switching assembly 200 being movable to open and connect the two adjacent drying chambers 101 or close and isolate the two adjacent drying chambers 101; a vacuum assembly 300 connected to the drying chambers 101 for removing gas from the drying chambers 101; and a heating assembly 400 disposed in the housing 100 for providing a heat source to the drying chambers 101.

[0025] In this embodiment, at least two drying chambers 101 are provided in the housing 100, and a switch assembly 200 is provided between two adjacent drying chambers 101. The movement of the switch assembly 200 controls the connection or disconnection of the two adjacent drying chambers 101. In this way, the user can use one of the drying chambers 101 individually to dry a small batch of materials, shorten the start-up time, reduce energy consumption, and improve drying efficiency; or multiple drying chambers 101 can be used simultaneously to achieve synchronous drying of a large batch of materials, shorten the waiting time, and improve drying efficiency. When one of the drying chambers 101 is used, the switching assembly 200 is in the closed state, and the two adjacent drying chambers 101 are isolated. At this time, the vacuum assembly 300 and the heating assembly 400 can act only on the designated drying chamber 101, providing negative pressure and a thermal environment to that drying chamber 101. Because the overall space of the drying chamber 101 is small, the evacuation time is short, the heating time is short, the entire start-up time of the drying chamber 101 from ambient temperature to drying temperature is short, the energy consumption is low, the drying efficiency is high, and the drying effect is good. When at least two drying chambers 101 need to be used, the switching assembly 200 is in the open state, and the two adjacent drying chambers 101 are connected. At this time, the vacuum assembly 300 and the heating assembly 400 can act on multiple drying chambers 101, providing negative pressure and a thermal environment to all multiple drying chambers 101. Since large batches of materials to be dried can be dried simultaneously, the drying waiting time of the materials to be dried is short, and the drying efficiency is high.

[0026] Specifically, the vacuum drying device for medical devices is configured as a combination of at least a housing 100, a switching assembly 200, a vacuum assembly 300, and a heating assembly 400. The housing 100 can be divided into at least two drying chambers 101 by at least one partition. Windows can be opened on the partitions to connect adjacent drying chambers 101. The switching assembly 200 can cover these windows to completely isolate adjacent drying chambers 101. Each drying chamber 101 is connected to the vacuum assembly 300 and is equipped with the heating assembly 400. Thus, the vacuum assembly 300 can remove gas from the corresponding drying chamber 101, and the heating assembly 400 can heat the drying chamber 101, providing a low-temperature, negative-pressure drying environment for the material to be dried within it. This avoids the aging effects of high-temperature drying on the material, extending its service life, and achieves rapid and comprehensive drying with excellent results. The vacuum drying device provided in this example can operate independently for a small-volume drying chamber 101, shortening the response time of the drying chamber 101, making it suitable for dehydration and drying of small batches of materials to be dried; it can also operate simultaneously for multiple large-volume drying chambers 101, shortening the drying waiting time of the materials to be dried, making it suitable for dehydration and drying of large batches of materials to be dried. It has a wide range of applications, low energy consumption, high drying efficiency, and good drying effect.

[0027] In one possible implementation, a through connection window 102 is provided between two adjacent drying chambers 101. The switch assembly 200 includes a torsion spring 210, an opening and closing plate 220, and a locking member 230. The opening and closing plate 220 is rotatably connected to the drying chamber 101 via the torsion spring 210. The locking member 230 is used to lock the opening and closing plate 220 when it is closed on the connection window 102.

[0028] In this embodiment, the specific configuration of the switch assembly 200 is optimized. Specifically, the switch assembly 200 is configured as a combination of at least a torsion spring 210, an opening / closing plate 220, and a locking member 230. The torsion spring 210 can be rotatably connected to the side wall of the drying chamber 101 near the connecting window 102 via a fixed shaft. The opening / closing plate 220 is drivenly connected to the torsion spring 210 and can rotate synchronously with the torsion spring 210 to move closer to or away from the connecting window 102, thereby closing or opening the connecting window 102 and realizing the isolation or connection of two adjacent drying chambers 101. The locking member 230 can be a structural component such as a pin. When the opening / closing plate 220 is closed onto the connecting window 102, the locking member 230 passes sequentially through the opening / closing plate 220 and the side wall of the drying chamber 101 to fix the opening / closing plate 220 to the side wall of the drying chamber 101, thereby improving the stability of the closed state. Of course, the locking element 230 can also be a magnetic structure, a snap-fit ​​structure, or other mechanical combinations, which will not be elaborated here.

[0029] In another example, the switch assembly 200 can also be a partition structure inserted into the housing 100. In this case, the switch assembly 200 can be pulled outward to connect two adjacent drying chambers 101; or it can be pushed inward to isolate two adjacent drying chambers 101. The switch assembly 200 provided in this example can be used as both an isolation structure for adjacent drying chambers 101 and a connection control structure for adjacent drying chambers 101. It is multifunctional, simple in structure, and easy to manufacture. Furthermore, when the switch assembly 200 is completely pulled out, complete convection between the two adjacent drying chambers 101 can be achieved, improving gas heat exchange efficiency, shortening the overall machine response time when drying large quantities of materials, and resulting in high drying efficiency.

[0030] In one possible implementation, the switch assembly 200 further includes a sealing gasket 240 disposed on the side of the opening / closing plate 220 facing the connecting window 102. This arrangement further enhances the isolation between adjacent drying chambers 101 in the closed state, improving the anti-interference capability of a single drying chamber 101 operating independently. Specifically, the sealing gasket 240 can be any of a polytetrafluoroethylene (PTFE) gasket, a flexible graphite spiral wound gasket, a cotton rubber sheet gasket, or an asbestos gasket. For example, but not limited to, the sealing gasket 240 is a cotton rubber sheet gasket.

[0031] In one possible implementation, the sealing gasket 240 is a sealing ring, the size of which is greater than or equal to the size of the connecting window 102. It can cover the outer periphery of the connecting window 102 when the opening and closing plate 220 is closed over it. This arrangement reduces the material used for the sealing gasket 240, lowering production costs, and completely covers the outer periphery of the connecting window 102, achieving a sealed connection between the opening and closing plate 220 and the side wall of the drying chamber 101. Specifically, the sealing ring can be an annular structure, which can be attached to the opening and closing plate 220 with adhesive or the like. The inner ring size of the sealing ring is larger than the maximum outer edge size of the connecting window 102, so that the connecting window 102 can be completely covered within the sealing ring, improving sealing performance.

[0032] In one possible implementation, a control component 500 is also included, disposed in the housing 100, and electrically connected to the switching assembly 200, the vacuum assembly 300, and the heating assembly 400. This configuration allows for intelligent control of the switching assembly 200, the vacuum assembly 300, and the heating assembly 400 via the control component 500, achieving automated operation of the vacuum drying device. Specifically, the control component 500 can be a control chip or a control motherboard, and can be disposed inside the housing 100. It is electrically connected to the switching assembly 200, the vacuum assembly 300, and the heating assembly 400 via cables, enabling control of the switching assembly 200 (opening / closing) and the vacuum assembly 300 and the heating assembly 400 (operating / stopping), thereby achieving intelligent control of the drying chamber 101 inside the housing 100.

[0033] In one possible implementation, the vacuum assembly 300 includes a vacuum pump 310, a vacuum main pipe 320, at least two vacuum branch pipes 330, and at least two control valves 340. One end of the vacuum branch pipe 330 is connected to the drying chamber 101, and the other end is connected to the vacuum pump 310 through the vacuum main pipe 320. At least one control valve 340 is provided on one vacuum branch pipe 330, and the control valve 340 is electrically connected to the control unit 500.

[0034] In this embodiment, the specific configuration of the vacuum assembly 300 is optimized. Specifically, the vacuum assembly 300 is configured as a combination of at least a vacuum pump 310, a vacuum main pipe 320, at least two vacuum branch pipes 330, and at least two control valves 340. The vacuum main pipe 320 is provided with at least two air inlets and one air outlet. The air outlet is connected to the vacuum pump 310, and the air inlet is connected to one end of the vacuum branch pipe 330. The other end of the vacuum branch pipe 330 is connected to the drying chamber 101. In this way, the gas in the drying chamber 101 can be extracted by the vacuum pump 310 through the vacuum branch pipes 330 and the vacuum main pipe 320, so that the inside of the drying chamber 101 is kept in a negative pressure state, thereby reducing the vaporization temperature of water droplets adhering to the material to be dried, reducing the heat consumption of the subsequent heating assembly 400, reducing energy consumption, reducing the high-temperature aging problem of the material to be dried, and extending the service life of the material to be dried. The control valve 340 is installed on the vacuum branch pipe 330, which can be connected or disconnected to realize independent control of the vacuuming operation of each drying chamber 101.

[0035] In one possible implementation, the heating assembly 400 includes at least two heating elements 410, which are arranged around the peripheral wall of the drying chamber 101 and electrically connected to the control unit 500. This arrangement allows for heating and drying of the material to be dried around the periphery using the surrounding heating elements 410, further shortening the drying temperature response time and improving drying efficiency and effect. Specifically, the heating elements 410 can be heating strips, which can be snap-fitted or hung onto the inner wall of the drying chamber 101.

[0036] In one possible implementation, a heat insulation element 600 is also included, which is disposed on the inner peripheral wall of the drying chamber 101. The heat insulation element 600 can be heat insulation cotton, which can be adhered to the inner peripheral wall of the drying chamber 101 by adhesive. Alternatively, the heat insulation element 600 can be a heat insulation board, which is formed by pressing skeletal glass fiber and a high heat-resistant composite material, and can be connected to the inner peripheral wall of the drying chamber 101 by fasteners such as screws / bolts. The heat insulation element 600 can also be a heat insulation coating, which is applied to the inner peripheral wall of the drying chamber 101 by spraying. This arrangement can reduce heat loss and further improve the effective utilization rate of heat energy.
