Description

Technical Field

[0001] This utility model relates to the field of cell culture equipment technology, and in particular to a cell culture box. Background Technology

[0002] Previous incubators used a single door with a glass window. Due to temperature differences on both sides of the glass, fogging was common. To address this issue, existing technologies, such as an incubator with patent number CN116286343A, use an outer door and an inner glass door, a double-layered door system to solve the fogging problem. However, for general-purpose and standard incubators that require 180℃ high-temperature dry heat sterilization, the inner door is located inside the outer door, and the sensor switch for the inner door is also located inside the outer door and within the insulation layer of the cavity. During sterilization, excessively high temperatures can damage the sensor switch. Utility Model Content

[0003] The purpose of this utility model is to provide a cell culture chamber that solves the problem of how to set the door sensor switch of the existing culture chamber to avoid damage from high temperature.

[0004] This invention is implemented as follows: a cell culture chamber includes a cavity and an inner door and an outer door located at the opening of the cavity. The outer side of the cavity is provided with an insulation layer and a sensing component for detecting the opening and closing of the inner door. The sensing component includes:

[0005] A trigger element is located between the cavity opening and the outer door and can be connected to the inner door;

[0006] The sensing element is located on the outside of the insulation layer;

[0007] A transmission component is used to connect the trigger and the sensor.

[0008] To prevent fogging of the observation window, the cell culture incubator uses a double-door design. The sensor on the inner door, being close to the cavity, is easily affected by the high temperature of the cavity, thus reducing the lifespan of the sensor. In this invention, the sensor component is located on the outside of the insulation layer, separated from the cavity by the insulation layer, thus avoiding the impact of the cavity's high temperature on the sensor. Considering the closing of the outer door, the trigger component that works with the sensor is located on the inner side of the outer door between the cavity opening and the outer door. In this case, there is a relatively large distance between the trigger component and the sensor. To address this issue, a transmission component connects the trigger component and the sensor component. When the trigger component is activated by the inner door, the activation action is transmitted to the sensor component through the transmission component, thereby sensing the opening and closing status of the inner door.

[0009] A further technical solution of this utility model is: the triggering element is movable and connected to the transmission element in a transmission manner, and the transmission element is rotatable for entering and exiting the sensing area of ​​the sensing element. When the triggering element is triggered by the closing of the inner door, the triggering element moves and drives the transmission element to rotate. When the transmission element rotates, it enters the sensing area of ​​the sensing element, thereby being sensed by the sensing area as the inner door is closed.

[0010] A further technical solution of this utility model is as follows: the transmission component includes a rotatable and elastically arranged inclined portion. One end of the inclined portion is provided with a connecting portion connected to a trigger, and the other end is provided with a sensing portion connected to a sensing element. When the trigger is triggered, the connecting portion drives the elastically arranged inclined portion to rotate, thereby causing the sensing portion to enter and exit the sensing area of ​​the sensing element. The transmission component in this utility model can effectively amplify the movement of the connecting portion at the sensing portion through the lever principle, making it easier for the sensing element to detect the signal. The lever principle amplifies the detection range, making the detection more sensitive and reliable.

[0011] A further technical solution of this utility model is that: an angle is formed between the connecting part and the inclined part, and an angle is formed between the sensing part and the inclined part. Since the inclined part forms angles with both the connecting part and the sensing part, it is easier to connect with the trigger element and the space occupancy is more reasonable.

[0012] A further technical solution of this utility model is: a protective cover is fitted over the outside of the sensing component to prevent obstruction of the sensing component's movement.

[0013] A further technical solution of this utility model is: the sensing component further includes a mounting component for mounting the transmission component, the mounting component having a rotating shaft connected to the transmission component and an elastic component, and the mounting component having multiple elastic component connection points. The transmission component is rotatably connected to the mounting component via the rotating shaft and elastically connected to the mounting component via the elastic component. When it is necessary to adjust the tightness of the transmission component, this can be achieved by installing the elastic component at different connection points.

[0014] A further technical solution of this utility model is: the inner door is provided with a protrusion that can be connected to the trigger. When the inner door is opened or closed, the protrusion contacts or separates from the trigger, thereby the sensor detects the inner door opening / closing signal, reducing the material consumption of the inner door and lowering costs.

[0015] The beneficial effects of this utility model are as follows: In this utility model, the sensing element of the sensing component is set on the outside of the insulation layer, and the insulation layer separates the sensing element from the cavity, thus avoiding the influence of the high temperature of the cavity on the sensing element; considering the closing problem of the outer door, the trigger element that cooperates with the sensing element is set on the inside of the outer door and between the cavity opening. At this time, there is a relatively large distance between the trigger element and the sensor. To address this problem, the trigger element and the sensing element are connected by a transmission element, so that when the trigger element is triggered by the inner door, the triggering action is transmitted to the sensing element through the transmission element, thereby realizing the sensing of the opening and closing status of the inner door.

[0026] Example 1:

[0027] Figure 1-3 A cell culture chamber is shown, including a cavity 1 and an inner door 2 and an outer door 3 located at the opening of the cavity 1. An insulation layer 4 is provided on the outer side of the cavity 1, and a sensing component 5 for detecting the opening and closing of the inner door 2 is provided. The sensing component 5 includes:

[0028] A trigger 51 is located between the opening of the cavity 1 and the outer door 3 and can be connected to the inner door 2;

[0029] The sensing element 53 is disposed on the outside of the insulation layer 4;

[0030] The transmission component 52 is used to connect the trigger component 51 and the sensing component 53.

[0031] To prevent fogging of the observation window, the cell culture incubator uses a double-door design. The sensor on the inner door, being close to the cavity, is easily affected by the high temperature of the cavity, thus reducing the lifespan of the sensor. In this invention, the sensor component is located on the outside of the insulation layer, separated from the cavity by the insulation layer, thus avoiding the impact of the cavity's high temperature on the sensor. Considering the closing of the outer door, the trigger component that works with the sensor is located on the inner side of the outer door between the cavity opening and the outer door. In this case, there is a relatively large distance between the trigger component and the sensor. To address this issue, a transmission component connects the trigger component and the sensor component. When the trigger component is activated by the inner door, the activation action is transmitted to the sensor component through the transmission component, thereby sensing the opening and closing status of the inner door.

[0032] In this embodiment, the trigger 51 is movable and connected to the transmission member 52. The transmission member 52 is rotatable and can move in and out of the sensing area of ​​the sensor 53. When the trigger is triggered by the inner door closing, the trigger moves and drives the transmission member to rotate. When the transmission member rotates, it enters the sensing area of ​​the sensor, thereby sensing the information that the inner door is closed.

[0033] In this embodiment, the transmission component 52 includes a rotatable and elastically arranged inclined portion 521. One end of the inclined portion 521 is provided with a connecting portion 522 connected to the trigger component 51, and the other end is provided with a sensing portion 523 connected to the sensing component 53. When the trigger component is triggered, the connecting portion drives the elastically arranged inclined portion to rotate, thereby causing the sensing portion to enter and exit the sensing area of ​​the sensing component. The transmission component in this invention can effectively amplify the movement of the connecting portion at the sensing portion through the lever principle, making it easier for the sensing component to detect the signal.

[0034] In another embodiment, the trigger and the transmission are an integral structure.

[0035] In this embodiment, the connecting portion 522 and the inclined portion 521 form an angle, and the sensing portion 53 and the inclined portion 521 also form an angle. The inclined portion forms an angle with both the connecting portion and the sensing portion, making it easier to connect to the trigger and also resulting in a more efficient use of space.

[0036] In this embodiment, a protective cover 6 is fitted over the outside of the sensing component 5 to prevent obstruction of the sensing component's movement.

[0037] In this embodiment, the sensing component 5 further includes a mounting component 54 for mounting the transmission component 52. The mounting component 54 is provided with a rotating shaft 55 connected to the transmission component 52 and an elastic element 56. The mounting component 54 has multiple connection points for the elastic elements 56. The transmission component is rotatably connected to the mounting component via the rotating shaft and elastically connected to the mounting component via the elastic elements. When it is necessary to adjust the tightness of the transmission component, this can be achieved by installing the elastic elements at different connection points.

[0038] In this embodiment, the inclined portion of the transmission component is rotatably and elastically connected to the mounting component. The inclined portion forms a lever, and the two ends of the inclined portion are respectively engaged with the trigger and the sensing component, so that the trigger signal of the trigger is amplified by the transmission component and sensed by the sensing component.

[0039] In this embodiment, the sensing element is placed above the mounting base.

[0040] In this embodiment, the inner door 2 is provided with a protrusion 21 that can be connected to the trigger 51. When the inner door is opened or closed, the protrusion contacts or separates from the trigger, thereby the sensor detects the inner door opening signal, reducing the material consumption of the inner door and lowering costs.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
