[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: See also Figure 1 - Figure 7A biosafety cabinet with an adjustable ultraviolet lamp comprises a biosafety cabinet body 1, a sealed door 101 is hingedly connected to the middle of the front of the biosafety cabinet body 1, a first sealed shell 102 is installed on the upper front part and the lower front part of the biosafety cabinet body 1 by bolts, and a second sealed shell 103 is installed on the back of the biosafety cabinet body 1 by bolts. The biosafety cabinet body 1, the sealed door 101, the first sealed shell 102, and the second sealed shell 103 form a relatively sealed biosafety cabinet structure, and the objects inside the biosafety cabinet can be stored and retrieved by opening and closing the sealed door 101.

[0023] A tempered isolation glass 2 is installed inside the biosafety cabinet body 1, and a sealed space is formed between the tempered isolation glass 2, the first sealing shell 102, the second sealing shell 103, and the biosafety cabinet body 1. The tempered isolation glass 2 can isolate the internal space of the biosafety cabinet body 1. The space formed between the tempered isolation glass 2, the biosafety cabinet body 1, and the sealed door 101 is used for storing and accessing materials. The sealed space is used to protect structures such as the long-tube ultraviolet lamp 7. At the same time, the long-tube ultraviolet lamp 7 and the circuits nearby can be isolated to ensure the safety of material storage and access.

[0024] An insulating protection plate 3 is fixedly installed on the inner wall of the biosafety cabinet body 1, and a plurality of insulating support frames 301 are fixedly installed on the sides of the insulating protection plate 3. A conductive metal rail 4 and a rack-type insulating guide rail 5 are arranged at the supporting position of the insulating support frame 301. The conductive metal rail 4 and the rack-type insulating guide rail 5 are arranged in parallel. A driving component 6 is arranged between the conductive metal rail 4 and the rack-type insulating guide rail 5. A long-tube ultraviolet lamp 7 is installed on the driving component 6. The insulating protection plate 3 can prevent the outer shell of the biosafety cabinet body 1 from being charged. The insulating support frame 301 can support the conductive metal rail 4 and the rack-type insulating guide rail 5. When the driving component 6 is working, the long-tube ultraviolet lamp 7 can be controlled to move, so as to adjust the position of the long-tube ultraviolet lamp 7, thereby ensuring that the materials inside the biosafety cabinet body 1 can receive better ultraviolet irradiation, so as to achieve better sterilization and disinfection effects.

[0025] The insulating protection plate 3, the insulating support frame 301, the conductive metal rail 4, the rack-type insulating guide rail 5, the driving assembly 6, and the long-tube ultraviolet lamp 7 are all located inside the sealed space; The driving assembly 6 includes two groups of driving structures, which are symmetrically distributed and operate synchronously. The driving structure includes a driving motor 601. The output end of the driving motor 601 is connected to a traveling gear 602 through a coupling. The traveling gear 602 is meshed with the rack surface of the rack-type insulating guide rail 5. An insulating clamping groove 603 is fixedly installed on the side of the traveling gear 602. The insulating clamping groove 603 is clamped with a conductive connector 604, and the insulating clamping groove 603 is fixed to one end of the conductive connector 604 by screws. The conductive connector 604 slides along the conductive metal rail 4, and the long-tube ultraviolet lamp 7 is installed between the conductive connectors 604 on the two driving structures.

[0026] The driving motor 601 can be connected to the conductive connector 604 via a wire, thereby completing the power supply to the driving motor 601 .

[0027] When the driving motor 601 is working, it can control the travel gear 602 to rotate. At this time, the rack of the rack-type insulating guide rail 5 faces the meshing restriction of the travel gear 602, and the conductive metal rail 4 restricts the sliding of the conductive connector 604, so that the travel gear 602, the insulating positioning groove 603, the conductive connector 604, and the long-tube ultraviolet lamp 7 roll forward synchronously.

[0028] Embodiment 2: Based on the above embodiment 1, further description is given.

[0029] See also Figure 1 , Figure 2 , Figure 3 Specifically, the top and bottom of the inner side of the biosafety cabinet body 1 are fixedly mounted with a support base 104; The upper and lower surfaces of the tempered insulating glass 2 are respectively inserted into corresponding support bases 104 , and the support bases 104 and the tempered insulating glass 2 are fixed by bolts.

[0030] The support base 104 can provide support force for the tempered insulating glass 2 , and at the same time, the tempered insulating glass 2 can be fixed by bolts to ensure the stability of the tempered insulating glass 2 .

[0031] Specifically, the tempered insulating glass 2 is a U-shaped structure, and the width of the vertical section of the tempered insulating glass 2 is equal to the inner width of the biological safety cabinet body 1 .

[0032] When the tempered insulating glass 2 is inserted into the supporting base 104 , the space at both ends of the tempered insulating glass 2 can be isolated.

[0033] Specifically, the conductive metal rail 4 is a parallel metal strip guide structure, and metal heads 401 are fixedly installed at both ends of the conductive metal rail 4 by bolts, a conductive wire 402 is fixedly installed at one end of the metal head 401, and one end of the conductive wire 402 passes through the insulating protection plate 3 and is connected to the circuit of the biosafety cabinet body 1.

[0034] When the metal head 401 is not installed, no current flows through the conductive metal rail 4, and then the metal head 401 is connected to the external circuit. In this way, when a circuit failure occurs in either the conductive metal rail 4 or the metal head 401, it is convenient to replace them.

[0035] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 Specifically, a motor bracket 6011 is fixedly installed on the side of the driving motor 601, a slide bar 6012 is fixedly installed on the bottom of the side of the motor bracket 6011, and a slide plate 6013 is fixedly installed on one end of the slide bar 6012 away from the motor bracket 6011; The slide bar 6012 slides along the non-rack surface of the rack-type insulating guide rail 5 , and the slide plate 6013 slides along the side surface of the rack-type insulating guide rail 5 .

[0036] The motor bracket 6011, the slide bar 6012, and the slide plate 6013 form a sliding structure, so that the driving motor 601 can only slide.

[0037] Since both the rack-type insulating guide rail 5 and the conductive metal rail 4 have an arc structure, the slide bar 6012 can effectively adapt to the sliding of the arc structure, and the slide plate 6013 can achieve the limiting function to ensure the stability of the motor bracket 6011 when sliding along the non-rack surface.

[0038] See also Figure 4 , Figure 5 , Figure 6 , Figure 7 Specifically, the insulating support frame 301 is two symmetrical L-shaped structures, and one end of the L-shaped structure is fixed to the conductive metal rail 4 by bolts, an insulating support bar 302 is fixedly installed on the side of one end of the L-shaped structure, and one end of the insulating support bar 302 is fixed to the middle part of the side of the rack-type insulating guide rail 5.

[0039] Through the special structure of the insulating support frame 301 and the insulating support bar 302, the possibility of generating electrification is small while ensuring the support of the conductive metal rail 4 and the rack-type insulating guide rail 5, thereby preventing the shell of the biosafety cabinet body 1 from being electrified.

[0040] At the same time, the arrangement of the insulating support frame 301 and the insulating support bar 302 will not affect the movement of the conductive connector 604 , the traveling gear 602 , the sliding rod 6012 and other structures.

[0041] Specifically, the conductive connector 604 is composed of a conductive metal rod 6041, an insulating connector 6042 and a flange 6043. The conductive metal rod 6041 moves along the inner side of the conductive metal rail 4. The insulating connector 6042 is fixed to one end of the conductive metal rod 6041, and the insulating connector 6042 is clamped with the insulating clamping groove 603. The other end of the conductive metal rod 6041 is fixed to the flange 6043, and the conductive metal rod 6041 is fixedly installed with the long tube ultraviolet lamp 7 through the flange 6043.

[0042] When the driving motor 601 rotates, the traveling gear 602 and the insulating clamping groove 603 are controlled to rotate synchronously, and then the insulating connector 6042, the conductive metal rod 6041, the flange 6043, and the long-tube ultraviolet lamp 7 rotate synchronously.

[0043] Since the traveling gear 602 will roll forward in the direction of the rack-type insulating guide rail 5, it will drive the insulating connector 6042, the conductive metal rod 6041, the flange 6043, and the long-tube ultraviolet lamp 7 to roll forward synchronously. Since the motor bracket 6011, the slide bar 6012, and the slide plate 6013 limit the driving motor 601, the driving motor 601 moves synchronously in the direction of the rack-type insulating guide rail 5.

[0044] Specifically, a plurality of spring members 6044 are fixedly mounted on the side of the conductive metal rod 6041 , a smooth metal ring 6045 is fixedly mounted on one end of the spring member 6044 , and the smooth metal ring 6045 moves along the side of the conductive metal rod 6041 .

[0045] When the conductive connector 604 is inserted into the side of the conductive metal rail 4, the spring member 6044 always remains in a compressed state, and the smooth metal ring 6045 maintains excellent conductivity and can conduct electricity by contacting the conductive metal rail 4, thereby avoiding the poor conductivity between the conductive metal rail 4 and the conductive metal rod 6041 and affecting the operation of the long tube ultraviolet lamp 7.

[0046] At the same time, the friction between the smooth metal ring 6045 and the conductive metal rod 6041 is relatively small, and when the smooth metal ring 6045 slides along the side of the conductive metal rod 6041, the impact generated will also be greatly reduced.

[0047] Specifically, a hexagonal clamping head 6046 is provided on one side of the insulating connector 6042 , and one end of the insulating clamping slot 603 is a hexagonal clamping slot structure, and the hexagonal clamping slot structure is matched and clamped with the hexagonal clamping head 6046 .

[0048] Through the hexagonal structure, after the insulating connector 6042 and the insulating clamping groove 603 are connected, the two can be ensured to rotate synchronously.

[0049] See also Figure 1 , Figure 2 Specifically, a plurality of ventilation and dustproof holes 1031 are provided on the side of the second sealing shell 103 .

[0050] The ventilation and dustproof holes 1031 are used to improve the heat dissipation effect of the electrical components inside the enclosed space.

[0051] Working principle: When the biosafety cabinet body 1 is in use, the sealed door 101 is opened to carry out material storage and access operations.

[0052] At the same time, the conductive wire 402, the metal head 401, the conductive metal rail 4, and the conductive connector 604 form a connected circuit, so that the long-tube ultraviolet lamp 7 obtains electrical energy from the outside and emits ultraviolet rays. At the same time, the elastic force of the spring part 6044 is used to keep the smooth metal ring 6045 in contact with the conductive metal rail 4 at all times, ensuring the stability of the power supply to the long-tube ultraviolet lamp 7. The long-tube ultraviolet lamp 7 emits ultraviolet rays and completes the work of disinfection and sterilization.

[0053] When the long-tube ultraviolet lamp 7 is working, the driving motor 601 works synchronously, thereby controlling the travel gear 602 to rotate. Since the non-rack surface of the rack-type insulating guide rail 5 has sliding limit on the motor bracket 6011, the slide bar 6012, the slide plate 6013, and the driving motor 601, and the rack surface of the rack-type insulating guide rail 5 has meshing limit on the travel gear 602, at this time, the driving motor 601 slides along the extension direction of the rack-type insulating guide rail 5, and the travel gear 602 rolls along the extension direction of the rack-type insulating guide rail 5. In this way, the insulating connector 6042, the conductive metal rod 6041, the flange 6043, and the hexagonal clamp 6046 will be driven to roll synchronously.

[0054] Since the conductive metal rail 4 and the rack-type insulating guide rail 5 are arranged from the outer top of the tempered insulating glass 2 to the outer bottom of the tempered insulating glass 2, it can be ensured that the long-tube ultraviolet lamp 7 moves from the outer top of the long-tube ultraviolet lamp 7 to the outer bottom of the long-tube ultraviolet lamp 7.

[0055] When the long-tube ultraviolet lamp 7 and the conductive connector 604 move from the head end position of the conductive metal rail 4 to the tail end position of the conductive metal rail 4, the driving motor 601 is controlled to reverse, and the long-tube ultraviolet lamp 7 and the conductive connector 604 can be controlled to move back to the head end. Then, the rotation direction of the driving motor 601 is switched cyclically to realize the cyclic movement of the long-tube ultraviolet lamp 7, realize the movement adjustment of the long-tube ultraviolet lamp 7, and ensure the disinfection and sterilization effect of the long-tube ultraviolet lamp 7 on the internal materials of the biological safety cabinet body 1.

[0056] The device can ensure the safety of the internal circuit of the biosafety cabinet body 1, expand the irradiation range of ultraviolet rays, and effectively ensure that all materials inside the biosafety cabinet body 1 can receive good ultraviolet irradiation effects, thereby ensuring the sterilization and disinfection effects of the device on the materials.

[0057] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
