Description

Technical Field

[0001] This application relates to the field of culture equipment technology, and in particular to an incubator. Background Technology

[0002] An incubator is a temperature-controlled chamber primarily used for culturing microorganisms, plant cells, and animal cells. Some incubators have a two-way temperature control system for both cooling and heating. They are essential experimental equipment in research departments of biology, agriculture, medicine, and environmental protection, and are widely used in experiments such as constant-temperature culture and constant-temperature reactions. The main features of incubators include: the chamber body uses polyurethane or other foam plastics as insulation materials, providing good insulation against external cold and heat; the inner cavity is mostly made of stainless steel, offering strong corrosion resistance; and it has heating, cooling, and automatic temperature control devices that can sensitively regulate the internal temperature. With the continuous development of biotechnology, higher requirements are being placed on incubators.

[0003] In related technologies, traditional incubators, due to their simple design, require operators to manually open or close the door using the handle on the incubator door.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] If the incubator has been used at high temperatures, the inner door of the incubator will also be hot due to the high temperature inside the incubator. If it is necessary to open the inner door to observe the cells or tissues inside the incubator or to conduct further experiments, the operator will need to manually open and close the inner door, which may result in burns to the operator and cause an experimental accident.

[0042] Today, with the development of technology, people have begun to conduct experimental cultures of many cells or tissues to improve their reproduction. Incubators are widely used equipment in research, teaching, and production in fields such as microbiology, biomedicine, gene recombination, and biopharmaceuticals, enabling cells or tissues to grow optimally. An incubator can simulate an environment suitable for the growth of a target tissue or cell by creating a suitable environment within its chamber. Since different target tissues and living cells require different environmental temperatures, most incubators can simulate both high-temperature and low-temperature environments.

[0043] like Figures 1 to 2 As shown, this embodiment of the disclosure provides an incubator. The incubator includes a chamber body 1, an inner door 2, and an outer door 3.

[0044] The inner door 2 is equipped with a locking device. The incubator also includes a control unit, which is configured to control the outer door 3 to be driven open by the outer door motor 301 according to a first command; and to control the outer door 3 to be driven open by the outer door motor 301 according to a second command. When the outer door 3 is open, the locking device of the inner door 2 locks the inner door 2. After the outer door 3 is opened, the locking device of the inner door 2 is unlocked, and the inner door 2 is driven open by the inner door motor 201.

[0045] In this embodiment, the first instruction and the second instruction are independent control instructions, meaning that the control unit does not need to execute the first instruction before executing the second instruction, nor does it need to execute the second instruction before executing the first instruction. For example, the control unit can control the outer door 3 to open according to the first instruction, or it can control the inner door 2 to open after controlling the outer door 3 to open according to the second instruction.

[0046] Specifically, when both the inner door 2 and the outer door 3 are closed, upon inputting the first command, the control unit controls the outer door motor 301 to drive the outer door 3 to open according to the first command.

[0047] When both inner door 2 and outer door 3 are closed, upon input of the second command, the control unit controls the outer door motor 301 to drive the outer door 3 to open. While the outer door 3 is open, the locking device of the inner door 2 locks the inner door 2. After the outer door 3 is opened, the control unit unlocks the locking device and controls the inner door motor 201 to drive the inner door 2 to open.

[0048] When the outer door 3 is opened, the locking device of the inner door 2 locks the inner door 2. This can be understood as the locking device of the inner door 2 locking the inner door 2 at the instant the outer door 3 is opened, so as to avoid motion interference between the outer door 3 and the inner door 2.

[0049] In some embodiments, the control unit is further configured to control the outer door 3 to be driven open by the outer door motor 301 according to the second instruction, and the locking device of the inner door 2 locks the inner door 2 when the outer door 3 is open. When the opening angle of the outer door 3 is greater than or equal to a preset angle, the locking device of the inner door 2 unlocks, and the inner door 2 is driven open by the inner door motor 201.

[0050] Specifically, the preset angle is 10°. For example, when the outer door 3 is opened to 10°, 20°, 30° or 40°, the control unit controls the locking device of the inner door 2 to unlock, and the inner door 2 is driven to open by the inner door motor 201 to avoid motion interference between the outer door 3 and the inner door 2.

[0051] In some embodiments, the control unit is further configured to control the outer door 3 to be driven to close by the outer door motor 301 according to a first instruction; control the inner door 2 to be driven to close by the inner door motor 201 according to a second instruction; lock the inner door 2 after the inner door 2 is closed; and control the outer door 3 to be driven to close by the outer door motor 301.

[0052] Specifically, when the outer door 3 is in the open state and the inner door 2 is in the closed state, a first command is input. The control unit controls the outer door motor 301 to drive the outer door 3 to close according to the first command.

[0053] When both outer door 3 and inner door 2 are open, a second command is input. The control unit controls the inner door motor 201 to drive the inner door 2 to close according to the second command. After the inner door 2 is closed, the control unit controls the locking device to lock the inner door 2, and controls the outer door motor 301 to drive the outer door 3 to close.

[0054] In some embodiments, the control unit is further configured to control the inner door 2 to be driven to close by the inner door motor 201 according to the second instruction, and to control the outer door 3 to be driven to close by the outer door motor 301 when the closing angle of the inner door 2 is greater than or equal to a predetermined angle.

[0055] Specifically, the preset angle is 10°. For example, when the inner door 2 is closed at 10°, 20°, 30° or 40°, the control unit controls the outer door 3 to be driven to close by the outer door motor 301.

[0056] In some embodiments, the control unit is further configured to control the inner door 2 to be driven to close by the inner door motor 201 according to a third instruction when the outer door 3 is in the open state, and to control the locking device of the inner door 2 to lock the inner door 2.

[0057] Specifically, when both outer door 3 and inner door 2 are open, a third command is input. The control unit then controls the inner door motor 201 to close inner door 2 according to the third command. After inner door 2 is closed, the control unit controls the locking device to lock inner door 2.

[0058] In some embodiments, the control unit is further configured to, when the outer door 3 is in the open state and the inner door 2 is in the closed state, control the locking device of the inner door 2 to unlock the inner door 2 according to a third instruction, and control the inner door 2 to be driven open by the inner door motor 201.

[0059] Specifically, when the outer door 3 is in the open state and the inner door 2 is in the closed state, a third command is input. The control unit controls the locking device of the inner door 2 to unlock the inner door 2 according to the third command. After the inner door 2 is unlocked, the control unit controls the inner door motor 201 to drive the inner door 2 to open.

[0060] In some embodiments, the locking device includes a locking protrusion 204 and a first locking mechanism 101. The locking protrusion 204 is disposed on the edge of the inner door 2. The first locking mechanism 101 is disposed on the housing 1 at a position corresponding to the locking protrusion 204, and the first locking mechanism 101 includes a movable locking stop 1012.

[0061] Specifically, the locking stop 1012 is moved to the unlocked position, releasing the locking protrusion 204, thereby unlocking the inner door 2. The locking stop 1012 is moved to the locked position, stopping the locking protrusion 204, thereby locking the inner door 2.

[0062] Specifically, when the inner door 2 is closed, the locking stop 1012 is in the locked position to lock the inner door 2. At this time, the control unit controls the locking stop 1012 to move to the unlocked position, releasing the locking protrusion 204 to unlock the inner door 2, and controlling the inner door 2 to be driven open by the inner door motor 201. Similarly, when the inner door 2 is open, the locking stop 1012 is in the unlocked position. At this time, the control unit controls the inner door 2 to be driven closed by the inner door motor 201, and after the inner door 2 is closed, controls the locking stop 1012 to move to the locked position to stop the locking protrusion 204 from locking the inner door 2. Figure 3 As shown, in some embodiments, the first locking mechanism 101 further includes a sliding rail 1013 and a first push rod 1011. The sliding rail 1013 is disposed in the housing 1 and serves as a sliding guide for the locking stop 1012. The first push rod 1011 is used to push the locking stop 1012 to slide along the sliding rail 1013.

[0063] The first push rod 1011 and the locking stop 1012 are fixedly connected. The sliding rail 1013 includes an unlocking end near the outside of the housing 1 and a locking end opposite to the unlocking end.

[0064] Specifically, when the door is in the open state, the locking stop 1012, which is movable in the first locking mechanism 101, is in its initial position, i.e., at the unlocked end of the sliding track 1013. When the inner door motor 201 receives the closing command, it starts to drive the first rotating member 202. The first rotating member 202, under the force of the inner door motor 201, starts to drive the inner door 2 to rotate towards the housing 1. When the inner door 2 moves to the designated position, the first push rod 1011 starts to move. The first push rod 1011 drives the locking stop 1012 to move along the sliding track 1013 to the locking end. At this time, the locking stop 1012 can lock the locking protrusion 204 to complete the function of locking the inner door 2.

[0065] In some embodiments, the sliding track 1013 includes a horizontally arranged first slide rail and a second slide rail. The locking stop 1012 includes a first sliding rod, a second sliding rod, and a stop rod connecting the first sliding rod and the second sliding rod. The first sliding rod and the second sliding rod slide along the first slide rail and the second slide rail, respectively, so that the stop rod locks the locking protrusion 204.

[0066] The first sliding rod, the second sliding rod, and the stop rod are set perpendicularly.

[0067] In some embodiments, the stop bar includes a lower bottom surface of a stop locking protrusion 204. An elastic pad is provided on the lower bottom surface of the stop bar stop locking protrusion 204.

[0068] like Figures 4 to 5As shown, the incubator provided in this embodiment further includes a magnetic absorbing sheet 203 and a second locking mechanism 102. The second locking mechanism 102 includes a second push rod 1021 and a magnetic element 1022. The magnetic absorbing sheet 203 is disposed on the edge of the inner door 2. The second push rod 1021 is telescopically disposed at a position on the chamber 1 corresponding to the magnetic absorbing sheet 203. The magnetic element 1022 is disposed on the second push rod 1021. When the second push rod 1021 extends, it can drive the magnetic element 1022 to approach and attract the magnetic absorbing sheet 203 to lock the inner door 2.

[0069] Specifically, when the door is open, the movable locking stop 1012 of the first locking mechanism 101 is in its initial position, i.e., at the end closest to the outside of the housing 1; the second push rod 1021 is in a retracted state. When the inner door motor 201 receives the closing command, it starts to drive the first rotating component 202. The first rotating component 202, under the force of the inner door motor 201, starts to rotate the inner door 2 towards the housing 1. When the inner door 2 moves to the designated position, the second push rod 1021 drives the magnetic element 1022 to extend, and the magnetic element 1022 attracts the magnetic piece 203 to lock the inner door 2. After the magnetic element 1022 attracts the magnetic piece 203, the first push rod 1011 drives the locking stop 1012 to move along the sliding track 1013 to the locking end. At this time, the locking stop 1012 can lock the locking protrusion 204 to complete the function of locking the inner door 2. Then the second push rod 1021 retracts, causing the magnetic element 1022 to move away and release the magnetic plate 203.

[0070] In some embodiments, the incubator further includes a magnetic chuck 203 and a second locking mechanism 102. The second locking mechanism 102 includes a second push rod 1021 and a magnetic element 1022. The magnetic chuck 203 is disposed on the edge of the inner door 2. The second push rod 1021 is telescopically disposed on the chamber 1 at a position corresponding to the magnetic chuck 203. The magnetic element 1022 is disposed on the second push rod 1021. When the second push rod 1021 extends or retracts, it can drive the magnetic element 1022 to attract the magnetic chuck 203 to lock the inner door 2.

[0071] Among them, the magnetic absorbing sheet 203 is made of metals such as iron, cobalt, and nickel that can be magnetized.

[0072] In some embodiments, the incubator further includes a magnetic chuck 203 and a second locking mechanism 102. The second locking mechanism 102 includes a second push rod 1021 and a magnetic element 1022. The magnetic chuck 203 is disposed on the edge of the inner door 2. The second push rod 1021 is telescopically disposed on the chamber 1 at a position corresponding to the magnetic chuck 203. The magnetic element 1022 is disposed on the second push rod 1021. When the second push rod 1021 extends or retracts, it can drive the magnetic element 1022 to attract the magnetic chuck 203 to lock the inner door 2.

[0073] The magnetic element 1022 is a permanent magnet. When the door is open, the movable locking stop 1012 of the first locking mechanism 101 is in its initial position, i.e., at the end closest to the outside of the housing 1; the second push rod 1021 is in a retracted state. When the inner door motor 201 receives the closing command, it starts to drive the first rotating component 202. The first rotating component 202, under the force of the inner door motor 201, starts to drive the inner door 2 to rotate towards the housing 1. When the inner door 2 moves to the designated position, the second push rod 1021 drives the magnetic element 1022 to extend, and the magnetic element 1022 attracts the magnetic piece 203 to initially lock the inner door 2. After the magnetic element 1022 attracts the magnetic piece 203, the first push rod 1011 drives the locking stop 1012 to move along the sliding track 1013 to the locking end. At this time, the locking stop 1012 can lock the locking protrusion 204 to complete the function of locking the inner door 2. Then the second push rod 1021 drives the magnetic attraction element 1022 to retract, releasing the magnetic attraction piece 203.

[0074] In some embodiments, the incubator further includes a magnetic chuck 203 and a second locking mechanism 102. The second locking mechanism 102 includes a second push rod 1021 and a magnetic element 1022. The magnetic chuck 203 is disposed on the edge of the inner door 2. The second push rod 1021 is telescopically disposed on the chamber 1 at a position corresponding to the magnetic chuck 203. The magnetic element 1022 is disposed on the second push rod 1021. When the second push rod 1021 extends or retracts, it can drive the magnetic element 1022 to attract the magnetic chuck 203 to lock the inner door 2.

[0075] The magnetic element 1022 is an electromagnet. When the door is open, the movable locking stop 1012 of the first locking mechanism 101 is in its initial position, i.e., at the end closest to the outside of the housing 1; the second push rod 1021 is in a retracted state and the magnetic element 1022 is de-energized. When the inner door motor 201 receives the closing command, it starts to drive the first rotating member 202. The first rotating member 202, under the force of the inner door motor 201, begins to rotate the inner door 2 towards the housing 1. When the inner door 2 moves to the designated position, the second push rod 1021 drives the magnetic element 1022 to extend and energizes the magnetic element 1022, causing it to generate magnetic force. The magnetic element 1022 then attracts the magnetic plate 203 to initially lock the inner door 2. When the magnetic element 1022 attracts the magnetic piece 203, the first push rod 1011 drives the locking stop 1012 to move along the sliding track 1013 to the locking end. At this time, the locking stop 1012 can lock the locking protrusion 204 to complete the function of locking the inner door 2. Then the magnetic element 1022 is de-energized and the second push rod 1021 drives the magnetic element 1022 to retract, releasing the magnetic piece 203.

[0076] In some embodiments, the incubator is further provided with a locking mounting hole 106, which is located at a position corresponding to the magnetic chuck 203. The second locking mechanism 102 is installed in the locking mounting hole 106, and the depth of the locking mounting hole 106 is equal to the length of the second push rod 1021 when fully extended.

[0077] In some embodiments, the inner door 2 further includes a first end connected to the first rotating member 202 and a second end opposite to the first end. A locking protrusion 204 and a magnetic clasp 203 are disposed at the second end of the inner door 2.

[0078] In some embodiments, the incubator further includes a first sensor 103 and a second sensor 104. The first sensor 103 is used to detect the opening and closing state of the inner door 2. The second sensor 104 is used to detect the opening and closing state of the outer door 3.

[0079] Specifically, when the door is open, the movable locking stop 1012 of the first locking mechanism 101 is in its initial position, i.e., at the end closest to the outside of the housing 1; the second push rod 1021 is in a retracted state. When the inner door motor 201 receives the closing command, it starts to drive the first rotating component 202. The first rotating component 202, under the force of the inner door motor 201, begins to rotate the inner door 2 towards the housing 1. When the first sensor 103 detects that the inner door 2 is closed, the second push rod 1021 drives the magnetic element 1022 to extend, and the magnetic element 1022 attracts the magnetic piece 203 to initially lock the inner door 2. After the magnetic element 1022 attracts the magnetic piece 203, the first push rod 1011 drives the locking stop 1012 to move along the sliding track 1013 to the locking end. At this time, the locking stop 1012 can lock the locking protrusion 204 to complete the function of locking the inner door 2. Then, the second push rod 1021 drives the magnetic element 1022 to retract, releasing the magnetic plate 203. At this time, after receiving the closing command, the outer door motor 301 starts to drive the second rotating component 302. The second rotating component 302, under the force of the outer door motor 301, starts to drive the outer door 3 to rotate towards the cabinet 1. Then, the second sensor 104 detects whether the outer door 3 is closed. Only after detecting that the outer door 3 is closed will the heating or cooling operation inside the cabinet 1 be performed to avoid causing safety hazards.

[0080] When the inner door motor 201 receives the command to open the inner door 2, it first uses the second sensor 104 to detect whether the outer door 3 is open or closed. If the outer door 3 is detected to be closed, the command to open the inner door 2 is rejected. If the outer door 3 is detected to be open, the first rotating component 202 is driven. The first rotating component 202, under the force of the inner door motor 201, begins to drive the inner door 2 to rotate in the opposite direction to the housing 1.

[0081] In some embodiments, the first sensor 103 and the second sensor 104 are pressure sensors.

[0082] Specifically, the first sensor 103 determines whether the inner door 2 is closed and to what extent it is closed by detecting the pressure applied by the inner door 2 to the housing 1; the second sensor 104 determines whether the outer door 3 is closed and to what extent it is closed by detecting the pressure applied by the outer door 3 to the housing 1.

[0083] In some embodiments, the incubator is provided with a pressure threshold. When the first sensor 103 detects that the pressure value of the inner door 2 on the chamber 1 is less than the first pressure threshold, it determines that the inner door 2 is not tightly closed; when the first sensor 103 detects that the pressure value of the inner door 2 on the chamber 1 is greater than the pressure threshold, it determines that the inner door 2 is tightly closed.

[0084] Specifically, when the incubator receives a heating or cooling command from inside chamber 1, it first uses a first pressure sensor to detect the pressure applied to chamber 1 by inner door 2 and compares it with a pressure threshold to determine the closing status of inner door 2. If inner door 2 is determined to be tightly closed, the incubator executes the heating or cooling command normally; if inner door 2 is determined to be not tightly closed, the incubator refuses to execute the heating or cooling command and issues a warning that inner door 2 is not closed properly. This avoids potential safety hazards.

[0085] like Figure 6 As shown, in some embodiments, the control unit further includes a command switch device 303. The command switch device 303 can input a first command, a second command, or a third command to the control unit.

[0086] Specifically, when the command switch device 303 inputs a second command to the control unit, and the control unit controls the outer door 3 and inner door 2 to open according to the second command, the inner door 2 should open only after the outer door 3 opens to an angle greater than or equal to a preset angle. Similarly, when the command switch device 303 inputs a second command to the control unit, and the control unit controls the outer door 3 and inner door 2 to close according to the second command, the outer door 3 should close only after the inner door 2 closes to an angle greater than or equal to a preset angle.

[0087] In some embodiments, the instruction switch device 303 includes an inner door switch 3031, an outer door switch 3032, and a main switch 3033.

[0088] Among them, the outer door switch 3032 is used to input a first command to the control unit, the main switch 3033 is used to input a second command to the control unit, and the inner door switch 3031 is used to input a third command to the control unit.

[0089] Specifically, when the outer door 3 of the incubator is closed and the outer door switch 3032 is pressed, the outer door motor 301 drives the second rotating component 302 to rotate, thereby opening the outer door 3. The second sensor 104 detects that the pressure value of the outer door 3 on the chamber body 1 is less than the pressure threshold, and then determines that the outer door 3 has changed to the open state. When the outer door switch 3032 is pressed again, the incubator first uses the first sensor 103 to detect the pressure value of the inner door 2 on the chamber body 1 and compares it with the pressure threshold to determine whether the inner door 2 is closed or open. If the incubator determines that the inner door 2 is closed, the outer door motor 301 drives the second rotating component 302 to rotate in the opposite direction, thereby closing the outer door 3. If the incubator determines that the inner door 2 is open, it refuses to execute the command to close the outer door 3 and issues a prompt that the inner door 2 is not closed.

[0090] When the inner door 2 of the incubator is closed and the inner door switch 3031 is pressed, the incubator first uses the second sensor 104 to detect the pressure value of the outer door 3 on the chamber body 1 and compares it with a pressure threshold to determine whether the outer door 3 is closed or open. If the incubator determines that the outer door 3 is open, the inner door motor 201 drives the first rotating component 202 to rotate, thereby opening the inner door 2. When the first sensor 103 detects that the pressure value of the inner door 2 on the chamber body 1 is less than the pressure threshold, it determines that the inner door 2 has changed to the open state. When the inner door switch 3031 is pressed again, the inner door motor 201 drives the first rotating component 202 to rotate in the opposite direction, thereby closing the inner door 2. If the incubator determines that the outer door 3 is closed when the inner door is opened, it refuses to execute the command to open the inner door 2 and issues a prompt that the outer door 3 is not open.

[0091] When the main switch 3033 is pressed while both the inner door 2 and outer door 3 of the incubator are closed, the outer door motor 301 drives the second rotating component 302 to rotate, thereby opening the outer door 3. The second sensor 104 determines that the outer door 3 is now open when it detects that the pressure value of the outer door 3 on the incubator body 1 is less than a pressure threshold. When the opening angle of the outer door 3 is greater than or equal to a preset angle, the inner door motor 201 drives the first rotating component 202 to rotate, thereby opening the inner door 2. The first sensor 103 and the second sensor 104 respectively detect the pressure values ​​of the inner door 2 and outer door 3 on the incubator body 1 and compare them with the pressure threshold. If the pressure values ​​of both the inner door 2 and outer door 3 on the incubator body 1 are less than the pressure threshold, it is determined that both the inner door 2 and outer door 3 are now open. When the main switch 3033 is pressed again, the inner door motor 201 drives the first rotating component 202 to rotate, thereby closing the inner door 2. The first sensor 103 determines that the inner door 2 is now closed when it detects that the pressure value of the inner door 2 on the incubator body 1 is greater than the pressure threshold. When the closing angle of the inner door 2 is greater than or equal to the preset angle, the outer door motor 301 drives the second rotating component 302 to rotate, thereby driving the outer door 3 to close. The opening and closing sequence of the inner door 2 and the outer door 3 is determined by the pressure values ​​detected by the first sensor 103 and the second sensor 104, as well as the rotation angles of the inner door motor 201 and the outer door motor 301, to ensure that the inner door 2 and the outer door 3 do not interfere with each other's movements.

[0092] In some embodiments, the instruction switch device 303 of the incubator can be a remote control switch. The inner door 2 and / or outer door 3 can be opened and closed remotely via wireless signals such as infrared signals and / or Bluetooth signals.

[0093] In some embodiments, the incubator further includes a sealing ring 105, which is disposed at the opening of the chamber 1 to improve the sealing of the chamber 1 when the inner door 2 is closed.

[0094] In some embodiments, the first rotating member 202 and the second rotating member 302 are hinges.

[0095] In some embodiments, the inner door 2 is a glass door, allowing the interior of the enclosure 1 to be viewed without opening the inner door 2.
