Description

Technical Field

[0001] This invention relates to the field of bacterial culture technology in biomedicine, and particularly to an observation device for a bacterial incubator. Background Technology

[0002] A bacterial incubator is a device for culturing and operating bacteria in an anaerobic environment. During the bacterial culture process, frequent observation of the culture status is necessary, so some bacterial incubators have observation windows embedded in their doors. However, in current bacterial incubators, when there is a significant temperature difference between the inside and outside of the incubator, the inner side of the observation window (located on the inside of the incubator) is prone to fogging, affecting normal observation. Scraping away the fog requires opening the entire door, and frequent door opening can negatively impact bacterial growth. Furthermore, after one batch of bacteria has been cultured, to culture the next batch, the entire door must be opened, the cultured batch removed, and the next batch placed on the shelf inside the incubator. This process of opening the entire door and removing bacteria can disrupt the constant temperature environment inside the incubator, increasing energy consumption. Summary of the Invention

[0003] In view of this, the present invention provides an observation device for a bacterial incubator to solve the problem that when it is necessary to scrape off the fog on the inner side of the observation window of the current bacterial incubator door during use, the entire door needs to be opened frequently, which will affect the normal growth of bacteria.

[0004] This invention provides an observation device for a bacterial incubator, specifically comprising: a bacterial incubator body; a door rotatably connected to the opening of the bacterial incubator body, with three rectangular openings evenly distributed on the front end face of the door; three support shelves evenly installed inside the bacterial incubator body; characterized in that three transparent observation panels are rotatably connected to the front end of the door, located in front of the three rectangular openings; a support frame is installed on the front side inside the bacterial incubator body, and a mist scraper assembly is provided inside the support frame; a foot-operated drive assembly is provided on the right side of the bacterial incubator body, and each support shelf has a through hole.

[0009] Furthermore, the defogging assembly includes a lifting frame, a U-shaped connecting plate, a connecting rack, a front and rear moving plate, a rubber scraper, and T-shaped sliding columns. There are three lifting frames, all slidably connected to the outside of four transverse limiting rods. The right side of the front ends of the three lifting frames is fixedly connected via the connecting rack, and a U-shaped connecting plate is fixedly connected to the front end of each lifting frame. Each U-shaped connecting plate has a front and rear moving plate slidably connected to its front side via eight T-shaped sliding columns, and the front and rear moving plates are fixedly connected to the eight T-shaped sliding columns. A spring is sleeved on the outside of each T-shaped sliding column between the U-shaped connecting plate and the front and rear moving plates, and a rubber scraper is provided in the middle of the front end of each front and rear moving plate.

[0010] Furthermore, the pedal-driven assembly includes a pedal, a fixed support plate, a vertical sliding rack, rectangular sliding sleeves, a linkage shaft, a linkage gear A, a drive rack, a transmission shaft, a linkage gear B, and a first transmission pulley. Four vertical guide rods are slidably connected to the pedal, and the lower ends of the four vertical guide rods are fixedly connected to the fixed support plate. A spring is sleeved on the outside of each vertical guide rod between the pedal and the fixed support plate, and a circular limiting block is provided at the upper end of each vertical guide rod. The fixed support plate is fixedly connected to the lower right end face of the bacterial culture chamber body. A vertical sliding rack is fixedly connected to the rear side of the upper end face of the pedal, and two rectangular sliding sleeves are slidably connected to the outside of the vertical sliding rack. The set is fixedly connected to the upper front side of the right end face of the bacterial culture chamber body; the linkage shaft is rotatably connected to the right side wall of the bacterial culture chamber body, and the linkage shaft passes through the right side wall of the bacterial culture chamber body; a linkage gear A is fixedly installed at both ends of the linkage shaft, and the linkage gear A at the left end of the linkage shaft meshes with the connecting rack, and the linkage gear A at the right end of the linkage shaft meshes with the vertical sliding rack; a drive rack is fixedly connected to the left side of the pedal; the transmission shaft is rotatably connected to the lower right end face of the bacterial culture chamber body, and a linkage gear B and a first transmission pulley are fixedly connected to the front end of the transmission shaft, and the first transmission pulley is located in front of the linkage gear B, and the linkage gear B meshes with the drive rack.

[0011] Furthermore, when the pedal is in the downward pressing state, the vertical sliding rack rotates clockwise with the right linkage gear A, the linkage shaft and the left linkage gear A, and the left linkage gear A moves upward with the connecting rack, the lifting frame, the U-shaped connecting plate, the T-shaped sliding column, the front and rear moving plates and the rubber scraper, and at this time the front end of the rubber scraper is in close contact with the rear side of the transparent observation plate.

[0012] Furthermore, it also includes a cleaning assembly, which is located at the lower front end of the main body of the bacterial culture chamber, and the lower front end of the main body of the bacterial culture chamber has heat dissipation holes; the cleaning assembly includes a cleaning brush, vertical guide rods, a transmission disc, a connecting rod, a rotating shaft, and a second transmission pulley.

A second transmission pulley is installed outside the rotating shaft, and the second transmission pulley is connected to the first transmission pulley via a belt.

[0013] Furthermore, when the transmission disc is rotating, the transmission disc drives the upper end of the connecting rod to rotate, and the lower end of the connecting rod drives the cleaning brush to move up and down reciprocally, and the bristles on the cleaning brush are in close contact with the front side of the bacterial culture chamber body.

[0014] The observation device for a bacterial culture chamber provided by the present invention has the following beneficial effects: 1. This invention, through the cooperation of a foot-operated drive component and a fog-scraping component, allows operators to remove fog from the rear side of a transparent observation panel by stepping down on the foot pedal. The operator can then remove their foot from the foot pedal and scrape the fog off the rear side of the panel again. This eliminates the need to open the cabinet door when removing fog from the rear side of the transparent observation panel, avoiding frequent door openings and thus preventing interference with normal bacterial growth.

[0015] 2. This invention, through the setting of three transparent observation plates, allows for the removal of a batch of bacteria from the bacterial culture chamber body when the bacteria have been cultured. Only one transparent observation plate needs to be opened, the bacterial culture medium placed on the corresponding support shelf is removed and replaced, and then the corresponding transparent observation plate is closed. This eliminates the need to open the entire chamber door during the entire replacement process; only one transparent observation plate needs to be opened. Furthermore, since the size of the rectangular opening is much smaller than the size of the front opening of the bacterial culture chamber body, it is less likely to disrupt the constant temperature environment inside the bacterial culture chamber body, thus effectively reducing the power consumption of the bacterial culture chamber body.

[0016] 3. This invention, through the cooperation of a foot-operated drive assembly and a cleaning assembly, enables the drive rack to move up and down simultaneously with the foot pedal. The drive rack, linkage gear B, transmission shaft, first transmission pulley, second transmission pulley, and rotating shaft then drive the transmission disc to rotate. The transmission disc, in turn, causes the upper end of the connecting rod to rotate, while the lower end of the connecting rod moves the cleaning brush up and down reciprocally. This allows the cleaning brush to remove debris adhering to the lower front ventilation holes of the bacterial culture chamber, preventing any impact on ventilation and improving the lifespan of the internal electrical components.

[0017] 4. By setting the rear edge of the left end of the connector strip as a chamfer, the present invention enables the connector strip to automatically slide to the right and then to the left under the action of the chamfer when the transparent observation plate is closed, without the need to manually pull the connector strip to the right. Finally, it can automatically insert into the rectangular socket, thereby improving the convenience of limiting the transparent observation plate after it is closed. Attached Figure Description

[0033] Two rectangular sliding cylinders 301 are fixedly installed symmetrically on the left side of the transparent observation plate 3, and a rectangular sliding block 303 is slidably connected inside each rectangular sliding cylinder 301. Each rectangular sliding block 303 has an insertion strip 304 that penetrates the left side wall of the rectangular sliding cylinder 301 at its left end. The rear edge of the left end of the insertion strip 304 is chamfered. By chamfering the rear edge of the left end of the insertion strip 304, when the transparent observation plate 3 is closed, the insertion strip 304 can automatically slide to the right and then to the left under the action of the chamfer without manually pulling it to the right. Finally, it can automatically insert into the rectangular socket 203, thereby improving the convenience of limiting the transparent observation plate 3 after it is closed. Each rectangular sliding block 303 has a pull rod 305 that penetrates the right side wall of the rectangular sliding cylinder 301 at its right end, and a synchronous pull rod 306 is fixedly connected between the right ends of the two pull rods 305. A spring is sleeved on the outside of each pull rod 305 inside the rectangular sliding cylinder 301. A frame-shaped sealing gasket 302 is provided at the edge of the rear end face of the transparent observation plate 3, and a handle 307 is provided on the left side of the front end face of the transparent observation plate 3, and the handle 307 is located to the right of the synchronous pull rod 306. When the transparent observation plate 3 is closed on the door 2, the left end of the insertion strip 304 is inserted into the rectangular insertion port 203, and the rear side of the frame-shaped sealing gasket 302 is in close contact with the front end face of the door 2, thereby improving the sealing performance of the transparent observation plate 3 after it is closed.

[0034] The support frame 4 has four horizontal limiting rods 401 fixedly connected inside, and four vertical sliding rods 402 are fixedly connected inside the support frame 4 in a left-right symmetrical manner, and the four vertical sliding rods 402 pass through the four horizontal limiting rods 401; each vertical sliding rod 402 is sleeved with a spring, so that the lifting frame 501 has downward elasticity.

[0035] The defogging assembly 5 includes a lifting frame 501, a U-shaped connecting plate 502, a connecting rack 503, a front and rear moving plate 504, a rubber scraper 505, and T-shaped sliding columns 506. There are three lifting frames 501, all slidably connected to the outside of four transverse limiting rods 401. The right side of the front end face of each of the three lifting frames 501 is fixedly connected via the connecting rack 503, and a U-shaped connecting plate 502 is fixedly connected to the front end face of each lifting frame 501. A front and rear moving plate 504 is slidably connected to the front side of each U-shaped connecting plate 502 via eight T-shaped sliding columns 506, and the front and rear moving plates 504 are fixedly connected to the eight T-shaped sliding columns 506. A spring is sleeved on the outside of each T-shaped sliding column 506 between the U-shaped connecting plate 502 and the front and rear moving plate 504, and a rubber scraper 505 is provided in the middle of the front end face of each front and rear moving plate 504. The pedal-driven assembly 6 includes a pedal 601, a fixed support plate 602, a vertical sliding rack 603, rectangular sliding sleeves 604, a linkage shaft 605, a linkage gear A 606, a drive rack 607, a transmission shaft 608, a linkage gear B 609, and a first transmission pulley 6010. Four vertical guide rods are slidably connected to the pedal 601, and the lower ends of the four vertical guide rods are fixedly connected to the fixed support plate 602. A spring is sleeved on the outside of each vertical guide rod between the pedal 601 and the fixed support plate 602, and a circular limiting block is provided at the upper end of each vertical guide rod. The fixed support plate 602 is fixedly connected to the lower right end face of the bacterial culture chamber body 1. A vertical sliding rack 603 is fixedly connected to the rear side of the upper end face of the pedal 601, and two rectangular sliding sleeves 604 are slidably connected to the outside of the vertical sliding rack 603. Both rectangular sliding sleeves 604 are fixedly connected to the pedal 601. A linkage shaft 605 is fixedly connected to the upper front side of the right end face of the bacterial culture chamber body 1; the linkage shaft 605 is rotatably connected to the right side wall of the bacterial culture chamber body 1, and the linkage shaft 605 passes through the right side wall of the bacterial culture chamber body 1; a linkage gear A606 is fixedly installed at both ends of the linkage shaft 605, and the linkage gear A606 at the left end of the linkage shaft 605 meshes with the connecting rack 503, and the linkage gear A606 at the right end of the linkage shaft 605 meshes with the vertical sliding rack 603; a drive rack 607 is fixedly connected to the left side of the foot pedal 601; a transmission shaft 608 is rotatably connected to the lower right end face of the bacterial culture chamber body 1, and a linkage gear B609 and a first transmission pulley 6010 are fixedly connected to the front end of the transmission shaft 608, and the first transmission pulley 6010 is located in front of the linkage gear B609, and the linkage gear B609 meshes with the drive rack 607; When the pedal 601 is in the downward pressing state, the vertical sliding rack 603 rotates clockwise with the right linkage gear A606, linkage shaft 605 and left linkage gear A606. The left linkage gear A606 moves upward with the connecting rack 503, lifting frame 501, U-shaped connecting plate 502, T-shaped sliding column 506, front and rear moving plate 504 and rubber scraper 505. At this time, the front end of the rubber scraper 505 is in close contact with the rear side of the transparent observation plate 3. By combining the foot-operated drive assembly 6 with the fog-scraping assembly 5, when it is necessary to remove fog from the rear side of the transparent observation panel 3, the operator can step down on the foot pedal 601 and then remove their foot from the foot pedal 601 to remove the fog from the rear side of the transparent observation panel 3. This eliminates the need to open the cabinet door 2 when removing fog from the rear side of the transparent observation panel 3, thus avoiding the frequent opening of the cabinet door 2 and preventing the normal growth of bacteria from being affected.

[0036] Example 2: Based on Example 1, such as Figure 1 and Figure 11As shown: It also includes a cleaning component 7, which is located at the lower front end of the bacterial culture chamber body 1, and the lower front end of the bacterial culture chamber body 1 has heat dissipation holes; the cleaning component 7 includes a cleaning brush 701, a vertical guide rod 702, a transmission disc 703, a connecting rod 704, a rotating shaft 705, and a second transmission pulley 706. A vertical guide rod 702 is slidably connected to both ends of the cleaning brush 701, and the two vertical guide rods 702 are fixedly installed on the front end of the bacterial culture chamber body 1; the connecting rod 704 is rotatably connected to the middle of the front end of the cleaning brush 701 through a rotating shaft; the rotating shaft 705 is fixedly connected to the center of the rear end of the transmission disc 703, and the rotating shaft 705 is rotatably connected to the front end of the bacterial culture chamber body 1. The second transmission pulley 706 is installed on the outside of the rotating shaft 705, and the second transmission pulley 706 is connected to the first transmission pulley 6010 through a belt; When the transmission disk 703 is rotating, the transmission disk 703 drives the upper end of the connecting rod 704 to rotate, and the lower end of the connecting rod 704 drives the cleaning brush 701 to move up and down back and forth, and the bristles on the cleaning brush 701 are in close contact with the front side of the bacterial culture box body 1. By combining the pedal-driven component 6 with the cleaning component 7, the cleaning brush 701 can move up and down repeatedly as the pedal 601 moves up and down. This allows the cleaning brush 701 to remove debris attached to the heat dissipation holes at the lower front face of the bacterial culture chamber body 1 during its up-and-down movement, thus avoiding affecting the ventilation effect of the heat dissipation holes at the lower front face of the bacterial culture chamber body 1 and improving the service life of the internal electrical components of the bacterial culture chamber body 1.

[0037] The specific usage and function of this embodiment: In this invention, when culturing bacteria, the inoculated bacterial culture medium is first placed on the support shelf 101 inside the bacterial culture chamber body 1, then the chamber door 2 is closed, and then the bacterial culture chamber body 1 is started to provide a constant temperature environment for the inoculated bacterial culture medium.

[0038] During bacterial culture, when fog forms on the rear surface of the transparent observation plate 3, the operator can press down on the foot pedal 601, causing it to move downwards along with the vertical sliding rack 603. This movement, in turn, causes the right-side linkage gear A606, linkage shaft 605, and left-side linkage gear A606 to rotate clockwise. The left-side linkage gear A606 then moves the connecting rack 503, lifting frame 501, U-shaped connecting plate 502, T-shaped sliding column 506, front-back moving plate 504, and rubber scraper 505 upwards. Because the front end of the rubber scraper 505 is in close contact with the rear side of the transparent observation plate 3, it removes the fog. The operator can then remove their foot from the foot pedal. The plate 601 is moved away, causing the pedal 601 to lose its downward pressing force. At this time, the pedal 601 quickly moves upward back to its original position under the action of the external spring of the vertical guide rod. Then, the pedal 601, along with the vertical sliding rack 603, a linkage gear A606 on the right, the linkage shaft 605, and the linkage gear A606 on the left, rotate counterclockwise. Then, the linkage gear A606 on the left moves the connecting rack 503, the lifting frame 501, the U-shaped connecting plate 502, the T-shaped sliding column 506, the front and rear moving plate 504, and the rubber scraper 505 downward, thereby scraping the rear side of the transparent observation plate 3 again. Thus, when scraping the fog on the rear side of the transparent observation plate 3, it is not necessary to open the box door 2, avoiding the frequent opening of the box door 2, thereby avoiding affecting the normal growth of bacteria.

[0039] When a batch of bacteria needs to be removed from the main body 1 of the bacterial culture chamber, firstly, open the upper transparent observation plate 3, then remove the bacterial culture medium placed on the upper support shelf 101, and then replace the next batch of bacteria to be cultured. After placing them, close the upper transparent observation plate 3, and then open and close the other two transparent observation plates 3 in the same way to complete the replacement of the bacterial culture medium. During the entire replacement process, since it is not necessary to open the entire door 2, only the corresponding transparent observation plate 3 needs to be opened. Moreover, since the size of the rectangular opening 201 is much smaller than the size of the front opening of the main body 1 of the bacterial culture chamber, it is not easy to damage the constant temperature environment inside the main body 1 of the bacterial culture chamber, thereby effectively reducing the power consumption of the main body 1 of the bacterial culture chamber.

[0040] During the up-and-down movement of the pedal 601, the drive rack 607 moves up and down together. Then, the drive rack 607 drives the linkage gear B609 to rotate, and the transmission shaft 608 drives the first transmission pulley 6010 to rotate. The first transmission pulley 6010 then drives the second transmission pulley 706 to rotate via a belt, thereby driving the rotating shaft 705 and the transmission disc 703 to rotate. The transmission disc 703 then drives the upper end of the connecting rod 704 to rotate, and the lower end of the connecting rod 704 drives the cleaning brush 701 to move up and down reciprocally. Because the bristles on the cleaning brush 701 are in close contact with the front side of the bacterial culture chamber body 1, the cleaning brush 701 can remove the debris attached to the heat dissipation holes at the lower front face of the bacterial culture chamber body 1 during the up-and-down movement, thus avoiding affecting the ventilation effect of the heat dissipation holes at the lower front face of the bacterial culture chamber body 1 and improving the service life of the internal electrical components of the bacterial culture chamber body 1.
