Description

Technical Field

[0001] This utility model belongs to the field of biotechnology and relates to a vacuum storage box. Background Technology

[0002] In the field of biotechnology, cell culture technology is a crucial method for research in cell biology and molecular biology, playing an irreplaceable role. The cell culture process is inseparable from the incubator; the success of cell culture is closely related to the incubator. Incubators are indispensable experimental equipment in scientific research and teaching fields such as plants, microorganisms, and viruses, and are widely used in biological experiments. Especially for microorganisms living in high-temperature or negative-pressure environments, precise temperature and vacuum environment control is required, necessitating the use of vacuum incubators. Currently, vacuum incubators on the market are generally made of metal, making it difficult to clearly observe the culture dishes inside during vacuum culture. Furthermore, vacuum incubators lack surface reinforcement structures, resulting in relatively low overall strength and lifespan, and offering insufficient protection for the contents.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a layered culture dish vacuum storage box [application number: 202221432823.8], which includes a box body and a slide rail. A door is rotatably installed at one end of the box body, and a control box is fixedly connected to one side of the box body. A placement plate is slidably installed on the inner wall of the slide rail, and an anti-collision block is fixedly installed at the bottom of the slide rail. A connecting plate is slidably connected inside the slide rail, and several scale marks are opened on the surface of the connecting plate. A locking block is engaged inside the connecting plate, and a rotating block is fixedly installed on one side of the locking block. A spring is fixedly connected to one end of the locking block. However, the box body of this solution is not transparent, making it difficult to clearly observe the condition of the culture dishes inside the box during vacuum culture. It also lacks a reinforced surface structure and protection for the items inside the box, resulting in relatively weak overall strength and service life of the box body. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a vacuum storage box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The door is connected to the storage box body via a hinge structure. The storage box body is made of transparent plastic and is integrally molded. Multiple culture dish trays are arranged from top to bottom inside the vacuum storage chamber, with an observation space formed between adjacent trays. The surface of the storage box body has an integrally molded reinforcing structure. An electromagnetic three-way valve, connected to the vacuum storage chamber, is located on the side or back of the storage box body. A vacuum pump is externally connected to the electromagnetic three-way valve to evacuate the vacuum storage chamber to a vacuum state.

[0007] In the aforementioned vacuum storage box, the box reinforcement structure includes a back reinforcement rib, a side reinforcement rib, and an end reinforcement rib integrally formed with the storage box body. The back reinforcement rib is located on the back of the storage box body, the side reinforcement ribs are located on the left and right sides of the storage box body, and the end reinforcement ribs are located at the top and bottom ends of the storage box body. The tail end of the side reinforcement rib intersects with the back reinforcement rib and the two are integrally formed at the intersection and connection point. The two ends of the end reinforcement rib intersect with the side reinforcement rib and the two are integrally formed at the intersection and connection point.

[0008] In the aforementioned vacuum storage box, the back reinforcing rib includes a back reinforcing frame plate disposed on the back of the storage box body.

[0010] In the aforementioned vacuum storage box, a first weight-reducing buffer groove is provided inside the side reinforcing horizontal bar and the side reinforcing vertical bar. The side reinforcing horizontal bar, the side reinforcing vertical bar, and the box back reinforcing frame plate together form a side protective space.

[0011] In the aforementioned vacuum storage box, the end reinforcing ribs include several end reinforcing crossbars respectively disposed at the upper and lower ends of the storage box body. The two ends of the end reinforcing crossbars intersect with the side reinforcing crossbars, and the two are integrally formed at the intersection.

[0012] In the aforementioned vacuum storage box, a second weight-reducing buffer groove is provided inside the end reinforcing crossbar, and the end reinforcing crossbar, the side reinforcing crossbar, and the box back reinforcing frame plate together form an upper and lower protective space.

[0013] In the aforementioned vacuum storage box, the hinge structure includes a door hinge and a hinge fixing seat. The hinge fixing seat is fixedly connected to one side of the front end of the storage box. One end of the door hinge is connected to the door, and the other end is screwed to the hinge fixing seat by screws. Several clips are provided on the end of the door away from the door hinge. A buckle plate is provided on the other side of the front end of the storage box, which is rotatably connected to the storage box and can engage with the clips.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, a vacuum storage box includes a storage box body 1, a vacuum storage chamber 2 inside the storage box body 1, a door 3 at the front end of the storage box body 1 that is rotatably connected to the storage box body 1 and used to seal the opening of the vacuum storage chamber 2, the door 3 being connected to the storage box body 1 via a hinge structure 4, the storage box body 1 being made of transparent plastic and integrally molded, multiple culture dish placement trays 5 arranged from top to bottom inside the vacuum storage chamber 2, an observation space 6 being formed between two adjacent culture dish placement trays 5, a box body reinforcement structure 7 integrally molded with the storage box body 1 on the surface of the box body 1, and an electromagnetic three-way valve 8 connected to the vacuum storage chamber 2 on the side or back of the storage box body 1, the electromagnetic three-way valve 8 being externally connected to a vacuum pump for drawing the vacuum storage chamber 2 to a vacuum state.

[0029] In this embodiment, during use, the culture dish containing microorganisms is placed on the culture dish placement tray 5, and multiple culture dish placement trays 5 are sequentially inserted into the vacuum storage chamber 2 inside the storage box 1. Then, the box door 3 is closed. The box door 3 is connected to the storage box 1 by a hinge structure 4 for easy rotation. The electromagnetic three-way valve 8 is opened, and the vacuum pump is started to evacuate the vacuum storage chamber 2 inside the storage box 1 to a vacuum state. The storage box 1 is made of transparent plastic, such as transparent acrylic or transparent PET material, to ensure that the culture dishes inside the storage box 1 can be observed under vacuum. An observation space 6 is formed between two adjacent culture dish placement trays 5. With the fully transparent box, blind spots are avoided. On the one hand, the storage box 1 adopts an integrated structure, making it less prone to deformation during use. On the other hand, the box reinforcement structure 7 can strengthen the overall structure of the storage box 1, improve the service life of the box, and enhance the protection of the items inside.

[0030] Combination Figure 1-6 As shown, the box reinforcement structure 7 includes a box back reinforcement rib 7a, a box side reinforcement rib 7b, and a box end reinforcement rib 7c integrally formed with the storage box 1. The box back reinforcement rib 7a is located on the back of the storage box 1, the box side reinforcement rib 7b is located on the left and right sides of the storage box 1, and the box end reinforcement rib 7c is located at the top and bottom ends of the storage box 1. The tail end of the box side reinforcement rib 7b intersects with the box back reinforcement rib 7a and the two are integrally formed at the intersection and connection point. The two ends of the box end reinforcement rib 7c intersect with the box side reinforcement rib 7b and the two are integrally formed at the intersection and connection point.

[0031] Specifically, the back reinforcing rib 7a strengthens the back of the storage box 1, the side reinforcing rib 7b strengthens the left and right sides of the storage box 1, and the end reinforcing rib 7c strengthens the top and bottom of the storage box 1. The back reinforcing rib 7a, the side reinforcing rib 7b, and the end reinforcing rib 7c are integrally formed with the storage box 1, making the storage box 1 less prone to deformation during use, improving the service life of the box, and strengthening the protection of the items inside.

[0032] Combination Figure 1-4 As shown, the back reinforcing rib 7a of the box includes a back reinforcing frame plate 7a1 disposed on the back of the storage box 1. The back reinforcing frame plate 7a1 is integrally formed with the storage box 1, and a back protection space 10 is formed between the back reinforcing frame plate 7a1 and the back plate 1a of the storage box 1.

[0033] In this embodiment, the back reinforcing frame 7a1 is square and matches the shape of the storage box 1. The back reinforcing frame 7a1 plays a role in structurally reinforcing the back of the storage box 1. The back protection space 10 can prevent direct impact on the back panel 1a of the storage box 1 during use, thus avoiding affecting the items inside the box. The structure is reasonable and compact, and the protection effect is good.

[0034] The side reinforcing ribs 7b of the box include two side reinforcing horizontal bars 7b1 and one side reinforcing vertical bar 7b2 respectively disposed on the left and right sides of the storage box body 1. The side reinforcing horizontal bars 7b1 and the side reinforcing vertical bar 7b2 are integrally formed with the storage box body 1. The two ends of the side reinforcing vertical bar 7b2 intersect with the two side reinforcing horizontal bars 7b1, and the intersection and connection are integrally formed. The side reinforcing horizontal bars 7b1 and the side reinforcing vertical bar 7b2 are provided with a first weight-reducing buffer groove 7b3. The side reinforcing horizontal bars 7b1, the side reinforcing vertical bars 7b2 and the box back reinforcing frame plate 7a1 together form a side protection space 11.

[0035] In this embodiment, the side reinforcing horizontal bars 7b1 and the side reinforcing vertical bars 7b2 provide structural reinforcement to the left and right sides of the storage box 1. The first weight-reducing buffer groove 7b3 can reduce the weight of the side reinforcing horizontal bars 7b1 and the side reinforcing vertical bars 7b2 on the one hand, and on the other hand, it can buffer the impact and improve the impact resistance. The side protection space 11 can prevent direct impact on the left and right side panels of the storage box 1 during use, thus avoiding affecting the items inside the box. The structure is reasonable and compact, and the protection effect is good.

[0036] The end reinforcing rib 7c includes several end reinforcing crossbars 7c1 respectively disposed at the upper and lower ends of the storage box 1. The two ends of the end reinforcing crossbars 7c1 intersect with the side reinforcing crossbars 7b1 and the two are integrally formed at the intersection. The end reinforcing crossbars 7c1 are provided with a second weight-reducing buffer groove 7c2. The end reinforcing crossbars 7c1, the side reinforcing crossbars 7b1 and the box back reinforcing frame plate 7a1 together form an upper and lower protective space 12.

[0037] In this embodiment, the end reinforcing crossbar 7c1 strengthens the structure of the upper and lower ends of the storage box 1. The second weight-reducing buffer groove 7c2 reduces the weight of the end reinforcing crossbar 7c1 and acts as a buffer, improving the impact resistance. The upper and lower protective spaces 12 prevent direct impact on the upper and lower end plates of the storage box 1 during use, thus avoiding damage to the items inside the box. The structure is reasonable and compact, and the protection effect is good.

[0038] Combination Figure 5-6 As shown, the hinge structure 4 includes a door hinge 4a and a hinge fixing seat 4b. The hinge fixing seat 4b is fixedly connected to one side of the front end of the storage box 1. One end of the door hinge 4a is connected to the door 3, and the other end is screwed to the hinge fixing seat 4b. The end of the door 3 away from the door hinge 4a is provided with several clips 3a. The other side of the front end of the storage box 1 is provided with a buckle plate 3b that is rotatably connected to the storage box 1 and can be engaged with the clips 3a. A pressure gauge 3c is installed on the door 3.

[0039] In this embodiment, the door 3 and the storage box 1 are rotatably connected by a door hinge 4a and a hinge fixing seat 4b. One end of the door hinge 4a is connected to the door 3, and the other end is screwed to the hinge fixing seat 4b. The disassembly and assembly are simple and convenient. When the door 3 is closed, the buckle plate 3b is rotated until it engages with the buckle head 3a to lock the door. The pressure gauge 3c can display the atmospheric pressure inside the storage box 1. Those skilled in the art should understand that the pressure gauge 3c can be a commercially available vacuum pressure gauge.

[0040] Combination Figure 2 , Figure 4 As shown, the storage box 1 has a sealing head 13 on its side or back that communicates with the vacuum storage chamber 2.

[0041] In this embodiment, when it is necessary to release the vacuum state inside the storage box 1, the sealing head 13 can be removed from the side or back of the storage box 1, so that the vacuum storage chamber 2 is connected to the outside world for natural ventilation or to connect an air filling device to introduce sterilized air into the storage box 1.

[0042] Combination Figure 4-5 As shown, the vacuum storage chamber 2 is equipped with several side-fixed slide rails 14, and the culture dish placement tray 5 slides in conjunction with the side-fixed slide rails 14.

[0043] In this embodiment, the culture dish placement tray 5 is slidably engaged with the side fixing slide rail 14, which facilitates the removal and fixing of the culture dish placement tray 5.

[0044] The working principle of this utility model is as follows:

[0045] In use, place the culture dish containing microorganisms on the culture dish placement tray 5, and insert multiple culture dish placement trays 5 sequentially into the vacuum storage chamber 2 inside the storage box 1. Then close the box door 3. The box door 3 is rotatably connected to the storage box 1 by the box door hinge 4a and the hinge fixing seat 4b. One end of the box door hinge 4a is connected to the box door 3, and the other end is screwed to the hinge fixing seat 4b. Disassembly and assembly are simple and convenient. After the box door 3 is closed, rotate the buckle plate 3b until it engages with the buckle head 3a to close the box door. Locked, pressure gauge 3c displays the atmospheric pressure inside storage box 1. Open the solenoid three-way valve 8 to start the vacuum pump, evacuating the vacuum storage chamber 2 inside storage box 1 to a vacuum state. Storage box 1 is made of transparent plastic, such as transparent acrylic or transparent PET material, ensuring that the culture dishes inside storage box 1 can be observed under vacuum. An observation space 6 is formed between two adjacent culture dish placement trays 5, which, together with the fully transparent box, avoids blind spots in observation. The back reinforcing frame 7a1 is square and is integrated with storage box 1. The shape is well-matched. The back reinforcing frame 7a1 strengthens the back of the storage box 1. The back protection space 10 prevents direct impact on the back panel 1a of the storage box 1 during use, thus protecting the items inside. The side reinforcing horizontal bars 7b1 and side reinforcing vertical bars 7b2 strengthen the left and right sides of the storage box 1. The first weight-reducing buffer groove 7b3 reduces the weight of the side reinforcing horizontal bars 7b1 and side reinforcing vertical bars 7b2 and also acts as a buffer, improving the impact resistance. The side protection space 11 prevents direct impact on the left and right side panels of the storage box 1 during use, thus protecting the items inside. The end reinforcing horizontal bars 7c1 strengthen the top and bottom of the storage box 1. The second weight-reducing buffer groove 7c2 reduces the weight of the end reinforcing horizontal bars 7c1 and also acts as a buffer, improving the impact resistance. The top and bottom protection spaces 12 prevent direct impact on the top and bottom end panels of the storage box 1 during use, thus protecting the items inside. The structure is reasonable and compact, providing good protection.

[0046] When it is necessary to release the vacuum in storage chamber 1, the sealing head 13 can be removed from the side or back of storage chamber 1, allowing the vacuum storage chamber 2 to be connected to the outside for natural ventilation or by connecting an air filling device to introduce sterilized air into storage chamber 1.

[0047] The culture dish placement tray 5 slides in conjunction with the side fixing slide rail 14, making it convenient to pick up and fix the culture dish placement tray 5.
