Description

Technical Field

[0001] The present invention relates to the technical field of aseptic operation equipment, in particular to a foldable and portable clean bench. Background Art

[0002] After sampling explants for plant tissue culture, they must be inoculated onto sterile culture media as quickly as possible. This is especially true for plant materials that are sensitive to temperature and other factors. Long-distance transportation can cause the explants to rapidly lose activity and easily cause them to brown and die after inoculation. Therefore, it is crucial to find a sterile operating environment as close to the sampling site as possible and to inoculate promptly.

[0003] However, in reality, sampling sites are often located in remote mountainous areas or in areas with inconvenient transportation, making it difficult to transport explants to laboratories with sterile operating conditions for inoculation. Transporting explants in constant-temperature containers prevents the timely elimination of microorganisms carried by the explants, and the high humidity during transportation causes microorganisms to multiply rapidly and even invade the explants, significantly increasing the infection rate after inoculation. While low-temperature transportation slows microbial proliferation, it is not suitable for temperature-sensitive plants, especially young and tender parts. Finding the optimal balance between various transportation methods is difficult.

[0004] If the sterile operating environment could be easily carried to the sampling site, all of the above problems could be effectively solved. Currently, the only sterile operating table that can be carried by one person is a simple box-shaped table designed for mushroom inoculation. This is not entirely suitable for inoculating plant explants and has various problems, such as being unable to fold and transport.

[0005] Therefore, a foldable portable clean bench is urgently needed. Summary of the Invention

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0049] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0050] See also Figures 1 to 8 As shown, an embodiment of the present application provides a foldable portable clean bench, comprising: a bottom plate 4, a front plate 1, a back plate 6, a top plate 7, a side plate 2 and a side plate 3. The front plate 1 and the back plate 6 are respectively foldably connected to two opposite long sides of the bottom plate 4. The side plates 2 and the side plates 3 are respectively foldably connected to two opposite short sides of the front plate 1. The top plate 7 is foldably connected to one length side of the back plate 6. The foldable portable clean bench has a folded state and a supported state. In the folded state, the back plate 6 is attached to one side of the bottom plate 4, the top plate 7 is attached to the back plate 6, the front plate 1 is attached to the other side of the bottom plate 4, and both side plates are attached to the side of the front plate 1 facing away from the bottom plate 4. In the supported state, the bottom plate 4, the front plate 1, the back plate 6, the side plates 2, the side plates 3 and the top plate 7 enclose a rectangular frame.

[0051] The foldable portable clean bench of the present application can be folded to reduce the size, which is convenient for carrying. When the sampling site is in the wild in the mountains or in a place with inconvenient transportation, it is difficult to transport the explants to a laboratory with sterile operating conditions for inoculation in time. If a constant temperature box is used for transportation, the microorganisms carried on the explants cannot be killed in time. The high humidity environment during transportation causes a large number of microorganisms to multiply and even invade the inside of the explants, and the infection rate after inoculation increases significantly. If low-temperature transportation is used, although the proliferation of microorganisms is slowed down, it is not suitable for plants that are sensitive to temperature, especially young and tender parts. Therefore, the foldable portable clean bench of the present application can be carried to conveniently carry the sterile operating environment to the sampling site.

[0052] In a possible embodiment, the folding portable clean workbench includes two folding support components 41 and two U-shaped beams 43. The two U-shaped beams 43 are arranged on both sides of the base plate 4 along the width direction. The U-shaped beams 43 have strip grooves. The two folding support components 41 are arranged on both sides of the base plate 4 along the length direction. Each of the folding support components 41 has two legs 411 arranged at intervals. The bases of the two legs 411 respectively extend into the corresponding strip grooves and are hinged to the U-shaped beams 43. In the folded state, the two legs 411 of the folding support component 41 are respectively accommodated in the corresponding strip grooves, and the legs 411 are immersed in the strip grooves and do not interfere with the rear plate 6.

[0053] In this embodiment, a foldable support member 41 is provided on the base plate 4 of the clean bench, eliminating the need for a separate support structure such as a table. When the clean bench is in use, the foldable support member 41 can be extended, allowing the legs 411 to extend out of the slots, perpendicular to the base plate 4, and supported on the ground or a platform, allowing the foldable portable clean bench to be positioned at a suitable height, making it convenient for the operator to operate.

[0054] In the embodiment of the present application, by providing a U-shaped beam 43, when in the folded state, the legs 411 can be immersed in the strip grooves to prevent interference between the rear plate 6 and the legs 411, thereby ensuring that the bottom plate 4 and the rear plate 6 have a good folding effect.

[0055] In a possible embodiment, a corner guard plate 5 is provided between the rear panel 6 and the bottom panel 4, and the corner guard plate 5 is foldably connected to the rear panel 6 and the bottom panel 4, respectively. In the folded state, the bottom panel 4 and the rear panel 6 are parallel, and the corner guard plate 5 is perpendicular to the bottom panel 4 and the rear panel 6, respectively. If the rear panel 6 and the bottom panel 4 are directly connected, they cannot be folded due to the setting of the U-shaped beam 43. In the present application, a corner guard plate 5 is provided between the rear panel 6 and the bottom panel 4, and the length of the corner guard plate 5 is the same as the length of the rear panel 6 and the bottom panel 4, and the width of the corner guard plate 5 is approximately the same as the width of the U-shaped beam 43. In this way, in the folded state, the corner guard plate 5 can be bent to be perpendicular to the bottom panel 4, and then the rear panel 6 is bent, so that the rear panel 6 is stably supported on the buffer device 42, and the rear panel 6 and the bottom panel 4 are parallel.

[0056] In one possible embodiment, a buffer device 42 is provided on the outer wall of the base plate 4. In a direction perpendicular to the base plate 4, the extension length of the buffer device 42 is greater than the extension length of the U-shaped beam 43. The provision of the buffer device 42 can provide a buffering effect during the folding process of the clean bench, preventing the base plate 4 and the rear plate 6 from rigid impact, avoiding collision damage, and extending the service life.

[0057] Specifically, the buffer device 42 may include a plurality of short buffer bodies, each of which is distributed in multiple rows and columns on the bottom wall of the cavity. For example, six buffer bodies may be provided, and the six buffer bodies are located between the two U-shaped beams 43 and are laid flat on the outer surface of the bottom plate 4. The height of the buffer body is slightly higher than the U-shaped beam 43. It plays the role of buffering the rear plate 6 to prevent severe friction between the surface of the rear plate 6 and the end of the support plate 43. The buffer body may be a protective foam. The buffer device 42 may also include two long strip-shaped buffer bodies, and the two long strip-shaped buffer bodies may be located on both sides of the bottom plate 4 along the width direction, and the two long strip-shaped buffer bodies are close to the corresponding U-shaped beam 43. Furthermore, the folding support component may also include a crossbeam connecting the two legs, the U-shaped beam having an inner beam and an outer beam, and an avoidance notch is provided on the inner beam. When the folding support component is in the folded state, the crossbeam passes through the avoidance notch of the corresponding inner beam, so that the legs can be accommodated in the strip groove.

[0058] In a possible embodiment, the folding support component 41 further includes a telescopic column 413, the support leg 411 has a hollow cavity, the telescopic column 413 is slidably connected to the hollow cavity, and the telescopic column 413 can slide along the length direction of the support leg 411 and can be fixed by a fastener b. The height of the clean bench can be adjusted to meet the needs of different operators. A plurality of positioning grooves can be provided along the length direction of the support leg 411, and a connecting hole can also be provided on the telescopic column 413. After the telescopic column 413 can slide along the length direction of the support leg to a set length, one end of the fastener b can be operated to pass through the connecting hole and connect to the corresponding positioning groove to fix the support leg and the telescopic column. Among them, the arrangement position of each buffer body located between the two U-shaped beams avoids the crossbeam of the folding support component 41. For example, multiple groups of buffer bodies can be arranged along the length of the base plate 4. Each group of buffer bodies includes two buffer bodies arranged sequentially along the width of the base plate 4. The buffer bodies in each group are spaced apart, and the two buffer bodies in each group are also spaced apart. When the folding support member 41 is in the folded state, the two legs 411 are located in the corresponding strip grooves, and the crossbeam is located between the two adjacent groups of buffer bodies. The base of the legs can be connected to the U-shaped beam 43 via a rotating shaft.

[0059] In one possible embodiment, the foldable portable clean bench further includes a support beam 44, one end of which is rotatably connected to the U-shaped beam 43 and the other end of which is detachably connected to the corresponding leg 411. For example, a hook portion is provided at the end of the support beam 44, and a hook mating portion is provided on the leg, and the hook portion is hooked to the hook mating portion. Alternatively, a connecting seat 411a is provided on the leg 411, and the connecting seat 411a has a threaded hole, and the connecting member d passes through the support beam 44 and connects to the threaded hole of the connecting seat 411a. A connecting member storage block c for accommodating the connecting member d can be provided on the bottom plate. The support beam 44, the U-shaped beam 43, and the folding support member 41 form a triangular stable structure. The support beam 44 can also limit the position of the folding support member 41, preventing it from folding. When the clean bench needs to be folded, the hook portion or the connecting member d of the support beam 44 can be removed and folded into the strip groove.

[0060] In one possible embodiment, the side panel has a fixed edge and four detachable connecting edges, wherein the fixed edge is foldably connected to the front panel 1. In the supported state, the four detachable connecting edges are respectively sealed to the rear panel 6, the bottom panel 4, the top panel 7, and the corner guard 5.

[0061] In this embodiment, one, two or three sides of each plate of the clean bench are connected to the adjacent plates and can be rotated 180° along the connecting axis. Folding in a zigzag shape can reduce the volume and facilitate carrying. After folding and assembly, it forms a hollow, approximately rectangular parallelepiped structure. Sealing strips are provided on the two sides where each plate is connected, and are connected and fixed by a connecting buckle 8. The connecting buckle 8 can be divided into two parts, a parent and a child, which are symmetrically connected to the two sides of the folded joint of each plate, and can tighten and fix the two plates after buckling. It can reduce the exchange of internal and external gases. Among them, the front plate 1, the rear plate 6, the bottom plate 4, the top plate 7, the side plates and the corner guard 5, the adjacent two are connected by a long hinge 0, and a connecting axis is provided in the long hinge 0 to achieve 180° rotation.

[0062] The sealing strip 9 may include a first strip 91 and a second strip 92. The first strip 91 and the second strip 92 are perpendicular to each other. The first strip 91 has a first clip groove, and the second strip 92 has a second clip groove. Of the adjacent panels, the connecting edge of one panel is inserted into the first clip groove, and the connecting edge of the other panel is inserted into the second clip groove, thereby achieving a sealed connection between the corresponding edges of the two adjacent panels. Each panel is also provided with a buckle body. The sealing strip may be provided with a buckle seam, into which each buckle body can be inserted, thereby securing the sealing strip in place and preventing it from falling off. For example, buckle seams may be provided on both the first strip 91 and the second strip 92 to accommodate the buckle bodies on the corresponding panels.

[0063] It should be noted that the connection and flipping direction between the plates of the clean bench are not limited to the above-mentioned methods. Any connection structure that can connect the two plates and enable the two plates to rotate relative to each other is within the scope of protection of this application.

[0064] In one possible embodiment, the foldable portable clean bench further includes a fresh air system 73, which is disposed on the outer side of the top plate 7. An air outlet 736 connected to the fresh air system 73 is disposed on the other side of the top plate 7. The fresh air system 73 includes a housing having an air inlet. An air duct extending from the air inlet to the air outlet 736 is disposed within the housing. A filter device and a fan 732 are disposed within the air duct.

[0065] In this embodiment, the outside air flows through the filter device under the action of the fan 732 and enters the internal sterile operating space from the air outlet 736, so that the operating space always maintains a positive pressure environment, further reducing the material contamination rate and extending the effective cleanliness maintenance time of one disinfection.

[0066] The filtering device may include a primary filter 733, a medium filter 734, and a high efficiency filter 735. The primary filter 733, medium filter 734, and high efficiency filter 735 are sequentially arranged along the air duct to improve the filtering effect. A dust filter 7301 may also be provided on the top plate 7, covering the air inlet outside the housing.

[0067] Furthermore, an air guide plate 731 is provided in the air duct, the side of the air guide plate 731 close to the air inlet is a wide end, and the side of the air guide plate 731 away from the air inlet is a narrow end, and the fan 732 is provided at the narrow end.

[0068] The top plate 7 is provided with an illumination lamp 72 and an ultraviolet disinfection lamp 71 , which can illuminate the operation space and disinfect the operation space.

[0069] Two operating ports 13 can be provided on the front panel 1, and a sleeve 14 is installed on the operating port 13. A sleeve clip 12 is provided at one end of the sleeve, and the sleeve clip 12 can be snapped onto the operating port 13. An elastic band 15 is provided at the other end of the sleeve 14. A transparent window 11 is also provided on the front panel 1 to facilitate the operator to see the inside of the clean bench. A take-out port 22 is provided on the side panel, and a closed door 21 is provided on the side panel. The closed door 21 is used to open or close the take-out port 22, and the closed door 21 is connected to the side panel 2 through a door hinge 23. The shell of the fresh air system has an openable and closable cover 730. When the cover 730 is opened, the internal structure can be easily disassembled, repaired and cleaned.

[0070] The top plate 7 of the foldable portable clean bench can be provided with an electric control box 737 and a switch 738, which are connected to the electric control box, which are electrically connected to the fan 732, the lighting lamp 72, the ultraviolet disinfection lamp 71 and the external power supply.
