Description

Technical Field

[0001] This utility model relates to the field of microbial incubator technology, and in particular to a microbial incubator that is easy to control in temperature. Background Technology

[0002] In many fields such as microbial research, medical testing, and biopharmaceuticals, microbial culture is a crucial basic experimental operation. Suitable temperature is one of the key factors for the normal growth and reproduction of microorganisms. Different types of microorganisms have specific requirements for culture temperature. Therefore, precise and stable control of the temperature inside the microbial incubator is of decisive significance for ensuring the quality of microbial culture and the accuracy of experimental results.

[0003] A search revealed a Chinese patent application with patent number 202120713561.1, which discloses a microbial incubator with temperature regulation function. The incubator includes a body, with a first incubation chamber and a second incubation chamber respectively disposed at the top and bottom of the inner wall of the body. Both the first and second incubation chambers are slidably connected to the inner wall of the body. A constant temperature heating plate is fixedly connected to the side of the first and second incubation chambers that are close to each other. A temperature display device is fixedly connected to the middle of one side of the body. A temperature detection device is fixedly connected to the side of the temperature display device that is close to the body. Air boxes are disposed on both the upper and lower sides of the temperature display device, and both air boxes are fixedly connected to the body.

[0004] The microbial incubator with temperature regulation function in the above-mentioned patent has the following shortcomings: Although the fan can accelerate the heat exchange inside the chamber, the fan only blows cold air into the chamber from one side, which causes uneven cooling inside the chamber and thus affects the cooling effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a microbial incubator that facilitates temperature control.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microbial incubator with easily controllable temperature includes a chamber body with a door hinged to one end. An intermediate ring is fixed between the inner wall of the top and the inner wall of the bottom of the chamber body. A placement assembly is movably connected to the inner wall of the bottom of the chamber body. A rotating column is movably connected to the top of the chamber body. The rotating column is driven to rotate by a driving component. Blades are fixed to the outer circumference of the rotating column. Air holes are opened on the outer circumference of the rotating column. An air cylinder is welded to the bottom of the rotating column. Spray holes are opened on the outer circumference of the air cylinder. A temperature sensor and a heating plate are fixed to the inner wall of the chamber body.

[0008] As a further embodiment of this utility model: the driving component includes a servo motor and an L-shaped plate. The L-shaped plate is fixed to the outer wall of the top of the box, and the servo motor is fixed to the inner wall of the top of the L-shaped plate. Both the output end of the servo motor and the outer wall of the rotating column are fixed with pulleys, and the two pulleys are driven by a synchronous belt.

[0009] As a further embodiment of this utility model: the placement assembly includes a placement tray, a vertical rod, and a turntable. The turntable is movably connected to the inner wall of the bottom of the box, and multiple placement trays are fixedly connected to each other by the vertical rod. The placement tray at the bottom is fixedly connected to the top of the turntable.

[0010] As a further improvement of this utility model: a top seat is fixed to the top of the box, and a control panel is installed on the surface of the top seat.

[0011] As a further embodiment of this utility model: a second rotating column is welded to the bottom of the air cylinder, and an installation ring is welded to the outer circumference of both the second rotating column and the outer circumference of the first rotating column. A connecting rod is fixed to the side wall of the installation ring by a pin, and a pad is welded to one end of the connecting rod.

[0012] As a further embodiment of this utility model: a T-shaped rod is movably connected to the through hole on the surface of the pad, and a scraper is fixed to one end of the T-shaped rod, and a spring is installed between the inner wall of one side of the T-shaped rod and the outer wall of one side of the pad.

[0013] As a further improvement of this utility model, filter screens are fixed to the top and bottom outer walls of the box.

[0014] As a further improvement of this utility model: the bottom of the box is fixed with a bottom seat, and the bottom of the bottom seat is movably connected with casters.

[0015] Compared with the prior art, this utility model provides a microbial incubator that facilitates temperature control, and has the following beneficial effects:

[0016] 1. The temperature sensor monitors the internal temperature of the chamber in real time. When the temperature is lower than the set value, the control panel automatically controls the heating plate to turn on. When the temperature is higher than the set value, the drive component drives the rotating column and blades to rotate, and the air is introduced into the air cylinder through the air hole and sprayed evenly from the nozzle to cool the middle ring, thereby reducing the internal temperature of the chamber and providing a stable and suitable temperature environment for microbial culture, which helps to improve the quality of microbial culture.

[0017] 2. The placement component is designed to be ring-shaped and rotatable. By rotating the placement tray, it is easy to pick up and put down the petri dishes placed at different positions on the placement tray. The operation is simple and quick, which improves the efficiency of the experiment. The outer walls of the top and bottom of the box are fixed with filter screens, which can effectively prevent dust from entering the middle ring.

[0018] 3. By setting a rotating column at the bottom of the air cylinder and using structures such as a mounting ring, connecting rod, pad, T-shaped rod, scraper, and spring, automatic cleaning of lint on the filter screen is achieved. When the drive unit drives the blades to rotate at a low speed, the scraper adheres to the outer circumference of the filter screen under the action of the spring force, and rotates along the outer circumference of the filter screen to clean the lint trapped by the filter, thus ensuring the ventilation performance of the filter screen.

[0019] 4. When the blades rotate at a high speed, the spring deforms under the action of centrifugal force, and the T-shaped rod slides outward relative to the pad. The scraper and the filter screen are temporarily separated, which avoids wear of the filter screen and scraper caused by long-term friction and extends the service life of the filter screen and scraper.

[0020] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1

[0031] A microbial incubator that allows for easy temperature control, such as Figures 1 to 7 As shown, the device includes a housing 1, a top seat 2 fixed to the top of the housing 1, a control panel 7 mounted on the surface of the top seat 2, a door 3 hinged to one end of the housing 1, an intermediate ring 8 fixed between the inner wall of the top and the inner wall of the bottom of the housing 1, a placement component rotatably connected to the inner wall of the bottom of the housing 1, a rotating column 12 rotatably connected to the top of the housing 1, the rotating column 12 being driven to rotate by a drive component, blades 25 fixed to the outer circumference of the rotating column 12 by screws, air holes 21 opened on the outer circumference of the rotating column 12, an air cylinder 24 welded to the bottom of the rotating column 12, a spray hole 23 opened on the outer circumference of the air cylinder 24, and a temperature sensor 9 and a heating plate 10 fixed to the inner wall of the housing 1 respectively.

[0032] The placement component can place the petri dishes. After the door 3 closes along the body 1, the control panel 7 is touch-sensitive and can set the culture temperature of the petri dishes. After the culture temperature is set using the control panel 7, the temperature sensor 9 monitors the ambient temperature inside the body 1. If the ambient temperature is lower than the set temperature, the temperature sensor 9 sends a signal back to the control panel 7. The control panel 7 then controls the heating plate 10 to turn on and raise the ambient temperature inside the body 1. When the ambient temperature reaches the set temperature, the power of the heating plate 10 is kept constant to keep the inside of the body 1 warm.

[0033] When the temperature sensor 9 detects that the ambient temperature inside the chamber 1 is higher than the set temperature, the temperature sensor 9 sends a signal back to the control panel 7. The control panel 7 controls the drive to drive the rotating column 12 and the blades 25 to rotate. During the rotation, the blades 25 generate airflow that is introduced into the rotating column 12 and the air cylinder 24 through the air holes 21. The airflow is finally ejected through the nozzles 23, which are evenly arranged in a ring on the outer circumference of the air cylinder 24. The airflow acts evenly on the surface of the intermediate ring 8 to cool the intermediate ring 8 and reduce the ambient temperature inside the chamber 1. When the ambient temperature inside the chamber 1 reaches the set temperature, the drive controls the rotating column 12 and the blades 25 to rotate at a constant speed to maintain the stability of the ambient temperature inside the chamber 1.

[0034] The driving components include a servo motor 15 and an L-shaped plate 16. The L-shaped plate 16 is fixed to the top outer wall of the housing 1 by bolts, and the servo motor 15 is fixed to the top inner wall of the L-shaped plate 16 by bolts. The output end of the servo motor 15 and the outer wall of the rotating column 12 are both fixed with pulleys by screws. The two pulleys are driven by a synchronous belt.

[0035] The servo motor 15 drives the rotating column 12 and blades 25 to rotate by the transmission action of the synchronous belt and pulley, so that the wind is evenly sprayed out through the nozzle 23.

[0036] The top and bottom outer walls of the housing 1 are both fixed with filter screens 6 by screws;

[0037] The filter screen 6 can prevent dust from entering the interior of the intermediate ring 8.

[0038] The placement assembly includes a placement tray 11, a vertical rod 27, and a turntable 13. The turntable 13 is rotatably connected to the inner wall of the bottom of the box 1, and multiple placement trays 11 are fixedly connected to each other by the vertical rod 27. The placement tray 11 located at the bottom is fixedly connected to the top of the turntable 13.

[0039] The placement tray 11 can hold culture dishes. By setting the placement component to be ring-shaped and rotatable, the culture dishes placed at different positions on the placement tray 11 can be picked up and put in by rotating the placement tray 11.

[0040] The bottom of the box 1 is fixed with a bottom base 4, and the bottom of the bottom base 4 is rotatably connected with casters 5;

[0041] The inclusion of casters 5 enhances the mobility of the entire incubator.

[0042] Working principle: If the ambient temperature is lower than the set temperature, the temperature sensor 9 sends a signal to the control panel 7. The control panel 7 then controls the heating plate 10 to turn on, raising the ambient temperature inside the chamber 1. Once the ambient temperature reaches the set temperature, the power of the heating plate 10 is kept constant to maintain the temperature inside the chamber 1. When the temperature sensor 9 detects that the ambient temperature inside the chamber 1 is higher than the set temperature, the driving component drives the rotating column 12 and blades 25 to rotate. During the rotation, the blades 25 generate airflow that is introduced into the rotating column 12 and the air cylinder 24 through the air holes 21. The airflow is finally ejected through the nozzles 23, which are evenly arranged in a ring on the outer circumference of the air cylinder 24, allowing the airflow to be emitted. A relatively large and uniform force is applied to the surface of the intermediate ring 8, and the wind power is used to cool the intermediate ring 8, thereby reducing the ambient temperature inside the chamber 1. When the ambient temperature inside the chamber 1 reaches the set temperature, the drive unit controls the rotating column 12 and the blade 25 to rotate at a constant speed, thereby maintaining the stability of the ambient temperature inside the chamber 1. The bottom inner wall of the chamber 1 is rotatably connected to a placement component. By setting the placement component to be ring-shaped and rotatable, the petri dishes placed at different positions on the placement tray 11 can be picked up and put in by rotating the placement tray 11. The top and bottom outer walls of the chamber 1 are both fixed with filter screens 6 by screws. The filter screens 6 can play a dust prevention role, preventing dust from entering the interior of the intermediate ring 8.

[0043] Example 2

[0044] A microbial incubator designed for easy temperature control, to facilitate the cleaning of flocculent material on the filter screen 6, such as... Figures 1 to 7 As shown, this embodiment makes the following additions based on embodiment 1: A rotating column 27 is welded to the bottom of the air cylinder 24, and an installation ring 26 is welded to the outer circumference of both the rotating column 27 and the outer circumference of the rotating column 12. A connecting rod 14 is fixed to the side wall of the installation ring 26 by a pin, and a pad 20 is welded to one end of the connecting rod 14. A T-shaped rod 22 is slidably connected to the through hole on the surface of the pad 20, and a scraper 18 is fixed to one end of the T-shaped rod 22. A spring 19 is installed between the inner wall of one side of the T-shaped rod 22 and the outer wall of one side of the pad 20.

[0045] The spring force of the spring 19 is used to make the scraper 18 and the outer wall of the filter screen 6 fit together. When the drive unit drives the blade 25 to rotate at a high speed, the spring 19 is deformed under the action of centrifugal force, and the T-shaped rod 22 slides outward relative to the pad 20. The scraper 18 and the filter screen 6 are temporarily separated, thereby avoiding long-term friction between the scraper 18 and the filter screen 6 when the blade 25 rotates at a high speed, which would cause the filter screen 6 and the scraper 18 to wear out to a large extent.

[0046] When the drive unit drives the blade 25 to rotate at a low speed, the scraper 18 scrapes off the fibrous material trapped on the filter screen 6 as it rotates along the outer circumference of the filter screen 6.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
