Fig. 1 schematically shows a side cross-sectional structural view of a joint structure in a closed state according to an embodiment of the present disclosure. Fig. 2 schematically shows a side cross-sectional structure view of a joint structure in an unfolded state according to an embodiment of the present disclosure.
As shown in fig. 1 and 2, the joint structure 100 according to this embodiment may include a joint 110, a stopper 120, and a sealing cover 130 for cooperating with the interface such that spaces at both ends of the interface are communicated or blocked. For convenience of understanding, the spaces at the two ends of the interface are respectively referred to as a first space and a second space, wherein the first space is a space located on the side of the limiting head 120, and the second space is a space located on the side of the sealing cover 130.
The joint 110 is in a hollow cylinder shape matched with the interface, and the joint 110 penetrates through the interface and is in telescopic connection with the interface. In the embodiment of the present disclosure, the joint 110 is slidable along its central axis direction under the action of an external force, that is, the joint 110 is retractable relative to the interface. The first through hole 111 is provided inside the joint 110, and the first through hole 111 may have a cylindrical shape such that a central axis of the first through hole 111 coincides with a central axis of the joint 110, in which case the joint 110 has an annular shape as viewed from both ends of the joint 110. The first via hole 111 penetrates the interface, and the first via hole 111 constitutes a part of a passage that communicates the first space and the second space. The sidewall of the first via hole 111 is provided with a circular opening 112, and the opening 112 is used for communicating the first via hole 111 with the space outside the connector 110.
It is to be understood that, in other alternative embodiments, the shape of the first via hole 111 may not be limited to the cylindrical shape of the above example, for example, the first via hole 111 may also have a triangular prism shape, a quadrangular prism shape, etc., as long as it can be used to communicate the first space and the second space. Likewise, the shape of the opening 112 is not limited to a circle, for example, the opening 112 may also be triangular, square, irregular, etc.
The limiting head 120 is in a hollow cylinder shape, one end of the limiting head 120 is connected with one end of the joint 110 close to the first space, for example, the limiting head 120 and the joint 110 can be in an integrated structure, and the other end of the limiting head 120 is externally connected with a pipeline. The stopper 120 is provided with a second through hole 121 therein, and the second through hole 121 is cylindrical and penetrates through the stopper 120. After the stopper 120 is connected to the joint 110, one end of the second through hole 121 communicates with the first through hole 111, the other end of the second through hole 121 communicates with the pipe, and the second through hole 121 constitutes one part of a passage communicating the first space and the second space. It should be understood that the shape of the second via hole 121 is not limited to the above-described cylindrical shape as long as it is sufficient to communicate the first via hole 111 with the pipe.
Alternatively, an end of the stopper 120 remote from the joint 110 may be provided with a flange member for connection with the pipe such that the second leading through hole 121 communicates with the pipe.
The sealing cover 130 has a solid cylindrical shape, and the sealing cover 130 is connected to an end of the joint 110 close to the second space such that an end of the first through hole 111 close to the second space is sealed, and the first through hole 111 can communicate with the second space only through the opening 112.
According to the joint structure 100 of the embodiment of the present disclosure, the end of the joint 110 near the first space is communicated with the external pipe by the stopper 120, and the end of the joint 110 near the second space is sealed by the sealing cover 130, so that the second via hole 121, the first via hole 111, and the opening 112 are sequentially communicated, thereby forming a passage for communicating the first space and the second space. Specifically, when the connector 110 moves along the interface to at least a portion of the opening 112 and passes out of the interface, the channel is smoothly conducted, and when the connector 110 moves to the opening 112 and is completely shielded by the sidewall of the interface, the channel cannot be conducted. Therefore, the opening 112 can be extended out of or into the interface by simply pushing and pulling the joint 110, so that the passage can be conducted or cut off, and the first space and the second space can be communicated or closed. That is, only the position of the joint 110 needs to be moved to separate the first space from the second space, so that the operation is simple and convenient, and the pollution caused by the gas in the first space entering the second space through the passage when the pipeline is directly detached from the joint 110 can be avoided.
According to an embodiment of the present disclosure, the joint structure 100 may further include a fixing portion 140, the fixing portion 140 is disposed in the interface and connected to a sidewall of the interface, and a fixing hole 141 for telescopically connecting with the joint 110 is disposed in the fixing portion 140. For example, the fixing portion 140 may have a substantially hollow cylindrical shape, and the fixing portion 140 is located in the interface, and the periphery of the fixing portion 140 is hermetically connected to the inner wall of the interface, so as to prevent air leakage from the interface. The fixing hole 141 in the fixing portion 140 has a cylindrical shape fitted to the outer circumference of the joint 110 so that the joint 110 can slide in the central axis direction of the fixing hole 141 to perform a telescopic function. In practical applications, the outer diameter of the joint 110 should be as close as possible to the inner diameter of the fixing hole 141 to avoid air leakage between the outer circumference of the joint 110 and the fixing hole 141. By providing the fixing portion 140, the sealing property between the interface and the joint 110 can be enhanced.
In some exemplary embodiments, the adaptor 110 may be screwed to the fixing portion 140, for example, an external thread may be provided on an outer wall of the adaptor 110, and an internal thread may be provided on an inner wall of the fixing hole 141 to match the external thread. When the joint 110 is driven to rotate relative to the fixing portion 140 by the screw, the joint 110 can move toward the second space or the first space, so as to control the opening 112 to penetrate out of the interface or be shielded by the sidewall of the interface, that is, the first space and the second space are connected or separated by the joint structure 100.
According to the embodiment of the present disclosure, the outer diameter of the stopper 120 is greater than the inner diameter of the fixing hole 141, so that the telescopic distance of the joint 110 may be restricted by the stopper 120. For example, when it is desired to communicate the first space with the second space, the joint 110 may be pushed to move toward the second space so that the opening 112 on the joint 110 can communicate with the second space. In this process, since the outer diameter of the stopper 120 is greater than the inner diameter of the fixing hole 141, the stopper 120 may contact the end of the fixing part 140 to restrict the movement of the joint 110, i.e., the joint 110 may not move toward the second space without limitation. In addition, in a state where the stopper 120 is in contact with the fixing portion 140, the opening 112 of the joint 110 is completely exposed in the second space, so that the efficiency of the opening 112 for conducting gas is maximized. Therefore, when the joint structure 100 of the present embodiment is used, the joint 110 is pushed to the position-limiting head 120 to abut against the fixing portion 140 every time, so that the gas-conducting efficiency of the joint structure 100 can be ensured to be maximized.
According to the embodiment of the present disclosure, the first magnet portion 122 is disposed on the limiting head 120, and at least a portion of the fixing portion 140 is configured as a metal structure that attracts the first magnet portion 122, so that the connection strength when the limiting head 120 abuts against the fixing portion 140 can be improved, thereby ensuring the stability of the air flow flowing through the joint 110.
For example, the first magnet portion 122 may be an annular magnet that surrounds the outer periphery of the stopper 120, and the first magnet portion 122 is disposed at one end of the stopper 120 near the interface. Accordingly, at least a portion of the fixing portion 140 near the end of the positioning head 120 is configured as a metal structure that is attracted to the first magnet portion 122, for example, at least a portion of the fixing portion 140 may be made of a ferrous material. When the joint 110 moves to the position-limiting head 120 to abut against the fixing portion 140, the attraction between the first magnet portion 122 and the metal structure on the fixing portion 140 is maximized, so that the position-limiting head 120 and the fixing portion 140 can abut tightly. Referring to fig. 2, when the position limiting head 120 abuts against the fixing portion 140, the connector 110 smoothly connects the first space and the second space, and at this time, under the action of the attraction force of the first magnet portion 122 and the fixing portion 140, the connection strength between the position limiting head 120 and the fixing portion 140 is improved, so that the connector 110 can stably connect the first space and the second space, and the problem that the opening 112 is closed due to the fact that the connector 110 is touched by mistake is avoided.
When the first magnet portion 122 is actually mounted, the attractive force between the first magnet portion 122 and the fixing portion 140 should be controlled not to be too large, so that the limiting head 120 is not driven to move against the fixing portion 140 by the attractive force alone, and the opening 112 is prevented from being automatically turned on.
According to the embodiment of the present disclosure, the sealing cover 130 is protruded from the outer circumference of the joint 110 to a further outer circumference, the outer diameter of the sealing cover 130 is larger than the inner diameter of the fixing hole 141, and the joint 110 may be prevented from being withdrawn from the mouthpiece by the sealing cover 130. For example, the sealing cover 130 may have a solid cylindrical shape, which is provided at an end of the joint 110 such that an end of the first via hole 111 is sealed. When it is desired to block the first space from the second space, the joint 110 can be pulled to move toward the first space, so that the opening 112 on the joint 110 can be completely blocked by the interface sidewall. Since the outer diameter of the sealing cover 130 is larger than the inner diameter of the fixing hole 141, when the joint 110 moves toward the first space, the sealing cover 130 eventually abuts against an end of the fixing portion 140 close to the first space to limit the movement of the joint 110, that is, the joint 110 does not move toward the first space without limitation. In a state where the sealing cover 130 is in contact with the fixing portion 140, the opening 112 of the joint 110 is completely blocked by the interface sidewall, so that the opening 112 cannot conduct gas. Therefore, when the joint structure 100 of the present embodiment is used, the joint 110 can be ensured to separate the first space and the second space only by pulling the joint 110 until the sealing cover 130 abuts against the fixing portion 140 each time. Meanwhile, the sealing cover 130 can prevent the joint 110 from being drawn out from the interface to the first space, so as to prevent the two ends of the interface from being directly conducted.
In some exemplary embodiments, the sealing cover 130 is detachably connected to the end of the joint 110, for example, the sealing cover 130 may be screwed to the end of the joint 110 near the second space, so as to facilitate the detachment and installation of the joint structure 100. In other embodiments, the sealing cover 130 may be integrated with the joint 110, so as to improve the connection strength between the joint 110 and the sealing cover 130, and avoid air leakage between the joint 110 and the sealing cover 130.
According to an embodiment of the present disclosure, the fixing portion 140 is provided with a second magnet portion 142, and at least a portion of the sealing cover 130 is configured as a metal structure that is attracted to the second magnet portion 142. Therefore, the connection strength of the sealing cover 130 against the fixing portion 140 can be improved, and the opening 112 is prevented from being easily conducted due to mistaken touch of the connector 110.
For example, the second magnet portion 142 may be an annular magnet that surrounds the end of the fixing portion 140 near the first space, and the second magnet portion 142 is fixedly connected to the end surface of the fixing portion 140. Accordingly, at least a portion of one end of the sealing cover 130 near the fixing portion 140 is configured as a metal structure that attracts the second magnet portion 142, for example, at least a portion of the sealing cover 130 may be made of a ferrous material. When the joint 110 moves to the sealing cover 130 to abut against the fixing portion 140, the attraction force between the second magnet portion 142 and the metal structure on the sealing cover 130 is maximized, so that the sealing cover 130 can abut against the fixing portion 140 tightly. Referring to fig. 1, when the sealing cover 130 abuts against the fixing portion 140, the joint 110 cannot connect the first space and the second space, and at this time, under the action of the attraction force between the second magnet portion 142 and the fixing portion 140, the connection strength between the sealing cover 130 and the fixing portion 140 is improved, so that the joint 110 can keep separating the first space and the second space, and the problem that the opening 112 is opened due to the mistaken touch of the joint 110 is avoided.
It should be noted that, when the second magnet portion 142 is actually installed, the attraction force between the second magnet portion 142 and the fixing portion 140 should be controlled not to be too large, so that the sealing cover 130 is not driven to move against the fixing portion 140 by the attraction force alone, and the opening 112 is prevented from being automatically closed.
With the above structural design, the joint structure 100 of the embodiment of the present disclosure has at least the following two working states:
as shown in fig. 1, the joint structure 100 is in a closed state. In the closed state, the sealing cover 130 abuts against the fixing portion 140, and the opening 112 on the connector 110 is completely blocked by the sidewall of the interface, i.e. the interface is not conductive. At this time, the pipe and the stopper 120 can be freely detached without moving the joint 110, and the connection of the interface is not caused. When the joint structure 100 is in the closed state, if it is required to communicate the first space with the second space, the joint 110 may be pushed at one side of the first space, so that the joint 110 moves toward the second space until at least a portion of the opening 112 passes through the interface, thereby achieving the spatial communication at the two ends of the interface.
As shown in fig. 2, the joint structure 100 is in an unfolded state. In the open state, the position limiting head 120 abuts against the fixing portion 140, and the opening 112 on the joint 110 passes through the interface and is completely exposed in the second space, i.e. the interface is conducted. At this time, the pipe may communicate with the second space through the second via hole 121 in the restriction head 120, the first via hole 111 in the joint 110, and the opening 112. When the joint structure 100 is in an open state, if the first space needs to be separated from the second space, the joint 110 may be pulled at one side of the first space, so that the joint 110 moves toward the first space until the opening 112 is completely covered by the side wall of the interface, thereby achieving the space separation at the two ends of the interface.
In addition, in the process that the joint 110 moves from the open state to the closed state or from the closed state to the open state, when the joint 110 moves to at least one part of the opening 112 to penetrate out of the interface, the opening 112 can conduct gas, and at this time, the first space and the second space at two ends of the interface are in a communication state.

FIG. 4 schematically illustrates a block diagram of an incubator sterilization system without a protective cover installed, according to another embodiment of the present disclosure. FIG. 5 schematically illustrates a cross-sectional view of an interface of an incubator sterilization system according to another embodiment of the present disclosure, wherein the connector structure is in a closed position. FIG. 6 schematically illustrates a cross-sectional view of an interface of an incubator sterilization system according to another embodiment of the present disclosure, wherein the joint structure is in an open state.
As shown in fig. 3 to 6, another embodiment of the present disclosure provides an incubator killing system 200, including: an incubator 210, on which an interface 211 is provided; a sterilizing device 220 for generating sterilizing gas; and the joint structure 100, the joint structure 100 is connected with the joint 211, when the joint structure 100 is installed, the sealing cover 130 is located inside the incubator 210, and the limiting head 120 is communicated with the killing device 220, so that the killing gas generated by the killing device 220 can enter the incubator 210 to kill, sterilize and stain the incubator 210.
For example, the incubator 210 may be a carbon dioxide incubator 210, i.e., a two-carbon box, for use with a cell workstation, and the sterilizing device 220 may be a hydrogen peroxide generator for generating gaseous hydrogen peroxide, i.e., the sterilizing gas generated by the sterilizing device 220 includes hydrogen peroxide that can sterilize and decontaminate the internal environment of the two-carbon box. The joint structure 100 is arranged at the joint 211 on the carbon dioxide tank, and the joint structure 100 is communicated with an inlet and outlet pipeline 221 of the hydrogen peroxide generator, such as a hose, so that gaseous hydrogen peroxide generated by the hydrogen peroxide generator can enter the carbon dioxide tank for killing. Moreover, due to the arrangement of the joint structure 100, when the inlet/outlet pipeline 221 of the hydrogen peroxide generator needs to be detached from the joint 211 of the second carbon tank, the joint 110 of the joint structure 100 can be pulled to the opening 112 and be completely shielded by the sidewall of the joint 211, so that the internal and external environments of the second carbon tank are isolated, and then the pipeline 221 is detached. Therefore, when the pipeline 221 is detached, air outside the second carbon box can be prevented from entering the second carbon box through the interface 211, and secondary pollution of the air to the internal environment of the second carbon box is avoided.
According to the embodiment of the present disclosure, a protective cover 212 is disposed on one side of the incubator 210 where the interface 211 is disposed, and the protective cover 212 is used for protecting the joint structure 100. As shown in fig. 3, the protective cover 212 is located outside the interface 211, and a through hole for passing the inlet/outlet pipe 221 of the sterilizing device 220 is formed in the protective cover 212, so that the protective cover 212 can prevent an operator from touching the interface 110 by mistake and causing air leakage of the interface 211.
Another embodiment of the present disclosure provides a method of using an incubator sterilization system 200, comprising: connecting the killing device 220 to the joint structure 100; applying an external force to the connector 110 to make the opening 112 of the connector 110 communicate with the inside of the cultivation box 210, thereby connecting the cultivation box 210 and the sterilizing device 220; starting the killing device 220, and closing the killing device 220 after the incubator 210 finishes killing; and applying an external force to the joint 110 to completely block the opening 112 of the joint 110 by the sidewall of the interface 211, and then detaching the killing device 220 from the joint structure 100.
The use method is described by taking a scene applied to dye removal of a two-carbon box as an example:
firstly, installing the joint 110 into the joint 211 of the carbon tank so that the sealing cover 130 is positioned inside the carbon tank and the limiting head 120 is positioned outside the carbon tank, and then communicating the inlet and outlet pipeline 221 of the hydrogen peroxide generator with the joint 110 to complete the communication between the hydrogen peroxide generator and the joint 110;
then, the connector 110 is pushed to the state shown in fig. 6, so that the interface 211 on the carbon two box is conducted;
then, starting the hydrogen peroxide generator, wherein hydrogen peroxide generated by the hydrogen peroxide generator can enter the carbon dioxide box through the pipeline 221 and the interface 211 for killing, dyeing and removing, and closing the hydrogen peroxide generator after the carbon dioxide box is killed;
then, the joint 110 is pulled to the state shown in fig. 5, so that the interface 211 on the two carbon tanks is closed, the air inside the two carbon tanks is isolated from the outside, and the inlet/outlet pipeline 221 of the hydrogen peroxide generator is detached from the joint 110, so that the dye removing operation of the two carbon tanks is completed.
In addition, the connector 110 is buried in the protective cover 212 in the whole decontamination process, so that the situation that the connector 110 is inserted into or pulled out of the interface 211 by mistake due to misoperation of personnel can be avoided.
Through the method, the secondary pollution to the internal environment of the second carbon box caused by the fact that air outside the second carbon box enters the second carbon box through the connector 211 when the pipeline 221 is detached can be avoided, and the joint structure 100 is convenient to install and use, low in cost and suitable for large-scale popularization.

(2) The connector structure 100 in the embodiment of the disclosure does not need complex operation when in use, only needs to push the connector 110 into the interface 211 before dye removal, and then pulls out the connector 110 after dye removal is completed, the operation is simple and fast, and the two ends of the connector 110 are respectively provided with the limiting head 120 and the sealing cover 130 for limiting, so that the worry that the pushing and pulling are not in place is avoided, and the design of the protective cover 212 is added, so that the dye removal efficiency can be improved to the maximum extent.
(3) The joint structure 100 in the embodiment of the present disclosure can be produced by opening the mold, and has mass production capability and low cost, which is convenient for mass production.
