In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0031] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0032] According to a first aspect of the present application, the present application provides a hardware box, which comprises a box body 11 and a first functional plate, the box body 11 is formed with a containing cavity 111 having an open end, and the first functional plate is installed on the open end to close the containing cavity 111. The first functional plate and the box body 11 form the outer wall of the containing cavity 111, and the containing cavity 111 is formed as a closed cavity having a closed space, so that the electronic components located in the closed space can be isolated from the external environment, reducing the risk of oxygen enrichment of the electronic components. The first functional plate of the present application can realize the functions of power transmission and / or signal transmission with the system inside and outside the hardware box through the active devices arranged thereon. Compared with the existing mechanical sealing method, the first functional plate can reduce the processing difficulty of sealing isolation, and the compactness of the hardware box as a whole can be improved.

[0033] The hardware box can include one or more power management circuits, which are located within the enclosed space of the accommodation cavity 111, and thus can be isolated from the external environment. In different embodiments, the power management circuits can be located on the first functional board, or can be located within the cavity of the accommodation cavity 111 and electrically connected to the first functional board through wires or connectors. The power management circuits located on the first functional board refer to the case where the power management circuits are not arranged on the surface of the first functional board facing the outside of the accommodation cavity 111. That is, as long as the power management circuits arranged on the first functional board are not exposed to the external environment of the accommodation cavity 111, they are described in this application as being arranged on the first functional board and located within the enclosed space of the accommodation cavity 111. When the power management circuits are located within the cavity of the accommodation cavity 111, the hardware box can include a second functional board built into the accommodation cavity 111 and separated from the first functional board, and the power management circuits are arranged on the second functional board; the second functional board is electrically connected to the first functional board through wires or connectors.

[0034] The power management circuits can implement voltage conversion of direct current, for example, converting the received direct current of the first voltage into direct current of the second voltage, thereby supplying power to other functional modules. When the power management circuits are used to supply power to functional modules with working power exceeding the power threshold, the design of the power management circuits enclosed in the accommodation cavity 111 can significantly reduce the risk of fire caused by the power management circuits due to the large working power when supplying power. The power threshold here can be defined and distinguished by the manufacturer, which is not limited in this application.

[0035] When the functional module is located outside the accommodating cavity, the first functional board is provided with a second interface module 41 facing the outer side of the hardware box, and the second interface module 41 is electrically connected with the power management circuit in the closed space, so that the power management circuit can supply power to the functional module outside the accommodating cavity through the second interface module 41. In this configuration, even if the power management circuit operates at a large working power due to external power supply, the risk of fire of the hardware box caused by oxygen enrichment can still be controlled since the power management circuit is enclosed in the accommodating cavity. Further, to avoid abnormal short circuit when the second interface module 41 is idle, the circuit on-off between the second interface module 41 and the power management circuit is controlled. When it is detected that no functional module is connected to the second interface module 41, the processor controls the power management circuit and the second interface module 41 to be in an off state, that is, the second interface module 41 is not powered at this time, and even if the terminals are short-circuited, no instantaneous large current will be formed. Only when it is detected that the functional module is indeed connected to the second interface module 41, the power management circuit will output power to the second interface module 41 to realize power supply through the second interface module. The second interface module can also include an information transmission interface. For example, when a plurality of second interface modules are provided on the first functional board, a part of the second interface modules are information transmission interfaces (which can be referred to as the first part of the second interface modules in this application), a part of the second interface modules are power transmission interfaces (which can be referred to as the second part of the second interface modules in this application), and a part of the second interface modules are used as both information transmission interfaces and power transmission interfaces (which can be referred to as the third part of the second interface modules in this application). Therefore, in some embodiments, at least part of the second interface modules can be used for information transmission.

[0036] When the functional module is located outside the accommodating cavity and the power management circuit is provided on the second functional board, the first functional board is further provided with a first interface module 42 facing one side of the accommodating cavity 111. The second functional board can be electrically connected with the second interface module 41 through the first interface module 42. Therefore, the power management circuit, the first interface module 42 and the second interface module 41 are electrically connected in sequence to supply power to the functional module provided outside the accommodating cavity 111. The first functional board and the second functional board can be connected through a cable assembly, or the two board cards can be arranged in parallel and electrically connected through a plug-in connector.

[0037] When the functional module is located in the accommodating cavity, the power management circuit can be connected with the functional module through other interface modules, or through the board card wiring, or through the cable assembly to realize power supply to the functional module. For example, when the power management circuit is arranged on the first functional board, the power management circuit can be connected with the functional module through the first interface module 42 (the first interface module 42 is arranged towards the inner side of the accommodating cavity 111, and the second interface module 41 is oppositely arranged on the two sides of the first functional board), or the power management circuit can be electrically connected with the functional module through the board card wiring of the first functional board. When the power management circuit is arranged on the second functional board in the accommodating cavity, the power management circuit can be connected with the functional module through the third interface module on the second functional board, or the power management circuit can be electrically connected with the functional module through the cable assembly or the board card wiring on the second functional board. When the working power of the functional module exceeds the power threshold value, the functional module itself and the power management circuit for supplying power to the functional module are arranged in the accommodating cavity, and the oxygen-enriched isolation of the load and the power supply element can be further realized.

[0038] The hardware box of the present application can further include a third functional board for converting the received alternating current into direct current of a first voltage, and outputting the direct current of the first voltage to the power management circuit. The power management circuit is used to convert the received direct current of the first voltage into direct current of a second voltage. When the AC-DC conversion and voltage conversion electronic elements of the present application are arranged in the closed space of the hardware box, the safety of the hardware box designed by the present application is further improved.

[0039] In one embodiment, the third functional board can be a power board 20, i.e. an AC-DC conversion board; the second functional board provided with the power management circuit can be a conversion board 30, i.e. a DC-DC conversion board; and the first functional board can be an interface board 40, which can be provided with components for realizing power supply in cooperation with the conversion board 30, or can be provided with components for realizing information transmission. When the hardware box of the present application is applied to an anesthesia machine, the AC-DC board can be used to convert the alternating current input to the AC-DC board by the auxiliary output device into a direct current, and then input the direct current to the DC-DC board; the DC-DC board converts the direct current into direct currents of different voltages required by each module of the anesthesia machine; the interface board 40 is connected with the DC-DC board to realize electrical connection between the DC-DC board and each module of the anesthesia machine, and the interface board 40 can also realize information interaction with each module of the anesthesia machine. The modules of the anesthesia machine include a display module, a turbine module, a battery module, a system switch module and a full electronic flowmeter module on the anesthesia machine.

[0040] The following embodiments are described by way of example with the second functional board and the third functional board arranged in the hardware box, the first functional board closing the open end, and the power management circuit arranged on the second functional board. However, it should be understood that the hardware box of the present application is not limited to the specific embodiments listed below. As described above, the power management circuit can be arranged on the first functional board, and the hardware box can be free of the third functional board and / or the second functional board, etc. However, since the hardware box adopts the manner of closing the power management circuit in the accommodating cavity and closing the accommodating cavity by the first functional board, the effects of the anti-oxygen-rich and compact design of the present application can be achieved.

[0041] Reference Figures 1 to 9 The hardware box comprises a box body 11, a power board 20, a conversion board 30 and an interface board 40. The box body 11 forms an accommodating cavity 111 with an open end. The power board 20 and the conversion board 30 are arranged in the accommodating cavity 111. The interface board 40 is mounted on the open end to close the accommodating cavity 111, so that the electronic devices on the power board 20, the conversion board 30 and the interface board 40 that need to be oxygen-rich sealed can be sealed in the accommodating cavity 111, and the electronic devices on the interface board 40 that do not need to be oxygen-rich sealed are exposed outside the accommodating cavity 111. The design of the hardware box not only can isolate the part of the electronic devices on the power board 20, the conversion board 30 and the interface board 40 from the oxygen-rich environment outside, but also can ensure that the other part of the electronic devices on the interface board 40 can be exposed outside the hardware box, so that the electric energy or information can be transmitted to the anesthesia machine.

[0042] In the prior art, the power board 20, the conversion board 30, the interface board 40 and the gas path components of the circuit system in the anesthesia machine are dispersed in the interior of the workbench or the interior of the main machine of the anesthesia machine, and do not form a systematic module. Meanwhile, the power board 20, the conversion board 30, the interface board 40 and the gas path components are not oxygen-rich sealed, which can easily cause the power board 20, the conversion board 30 and the interface board 40 to catch fire. The power board 20, the conversion board 30 and the interface board 40 are integrated in the hardware box of the present application, which not only facilitates the installation of the power board 20, the conversion board 30 and the interface board 40, and facilitates the subsequent maintenance of the power board 20, the conversion board 30 and the interface board 40, but also can isolate the power board 20, the conversion board 30 and the interface board 40 from the oxygen-rich environment of the gas path components, thereby playing a fireproof role.

[0043] In an optional embodiment, the interface board 40 comprises a first interface module 42 and a second interface module 41, the power board 20, the adapter board 30 and the first interface module 42 are sequentially electrically connected, and the second interface module 41 is electrically connected with the first interface module 42. The first interface module 42 is arranged on the side of the interface board 40 facing the accommodating cavity 111, and the arrangement position of the first interface module 42 can realize oxygen-enriched isolation of the electronic devices on the interface module, that is, the first interface module 42 is isolated from the oxygen-enriched environment outside; the second interface module 41 is arranged on the side of the interface board 40 facing the outside of the box body 11, so that the interface board 40 can be connected with each module of the anesthesia machine through the second interface module 41, for transmitting electric energy or information to the anesthesia machine and each module, that is, the second interface module 41 can be used as an electric socket and also as a communication interface with other modules of the anesthesia machine. The modules include but are not limited to a display module, a turbine module, a battery module, a system switch module and a full-electronic flowmeter module, etc.

[0044] For example, the power board 20 and the adapter board 30 are arranged in the accommodating cavity 111, and the interface board 40 is arranged on the open end to seal the electronic devices on the power board 20, the adapter board 30 and the interface board 40 which need oxygen-enriched sealing in the accommodating cavity 111, and the electronic devices on the interface board 40 which do not need oxygen-enriched sealing are arranged on the outside of the accommodating cavity 111. The electronic devices on the interface board 40 which do not need oxygen-enriched sealing include but are not limited to sockets and buzzers, etc.

[0045] For example, the power board 20 and the adapter board 30 are arranged on the bottom of the accommodating cavity 111; or the power board 20 and the adapter board 30 are arranged on the inner wall of the accommodating cavity 111; or the power board 20 and the adapter board 30 are arranged on two different side walls of the accommodating cavity 111; or one of the power board 20 and the adapter board 30 is arranged on the bottom of the accommodating cavity 111, and the other one of the power board 20 and the adapter board 30 is arranged on the side wall of the accommodating cavity 111; or the power board 20 and the adapter board 30 are arranged on the bottom of the accommodating cavity 111 and towards the open end of the accommodating cavity 111.

[0046] With the above technical solutions, the first interface module 42 and the second interface module 41 are integrated on the inner and outer surfaces of the interface board 40, the electronic device requiring oxygen-enriched sealing is arranged on the side of the interface board 40 facing the accommodating cavity 111, and the electronic device not requiring oxygen-enriched sealing is arranged on the other side of the interface board 40 and outside the accommodating cavity 111, so that the first interface module 42 can be connected with the adapter board 30 and sealed in the accommodating cavity 111, and the second interface module 41 can transmit electric energy or signals to each module of the anesthesia machine to realize ventilation control of each module of the anesthesia machine. Compared with arranging the first interface module 42 and the second interface module 41 on different board cards, the application can not only reduce the occupied space of the first interface module 42 and the second interface module 41 in the hardware box, but also reduce the manufacturing cost of the first interface module 42 and the second interface module 41, and facilitate the installation of the first interface module 42 and the second interface module 41.

[0047] In an optional embodiment, as shown in Figures 4 to 7 The hardware box further comprises a partition plate 13, wherein the partition plate 13 is arranged in the accommodating cavity 111, and the adapter board 30 is mounted on the partition plate 13, so as to form a layered layout with respect to the power supply board 20, which is beneficial to the miniaturization design of the hardware box as a whole.

[0048] At least part of the partition plate can be arranged to be spaced apart from the inner wall of the box body and divide the accommodating cavity 111 into two parts, and the power supply board and the adapter board are respectively mounted in the two spaces spaced apart by the partition plate (the two spaces can be closed spaces or two parts spaced apart by the partition plate). When the adapter board is mounted on the partition plate and the power supply board is directly or indirectly mounted on the inner wall of the box body, a layered layout of multiple board cards can be formed inside the box body of the hardware box. For example, the partition plate 13 is parallel to the bottom of the accommodating cavity 111, and both ends of the partition plate 13 are fixed on the side walls of the accommodating cavity 111, so that the power supply board 20 can be arranged below the partition plate 13, and the adapter board 30 can be arranged above the partition plate 13; or the partition plate 13 is perpendicular to the bottom of the accommodating cavity 111, the power supply board 20 is arranged on one side of the partition plate 13, and the adapter board 30 is arranged on the other side of the partition plate 13; or the partition plate 13 is arranged at an angle with respect to the bottom of the accommodating cavity 111, and the power supply board 20 and the adapter board 30 are distributed on both sides of the partition plate 13, which is not limited in the application.

[0049] In an optional embodiment, the partition plate 13 comprises a middle plate 131 and mounting plates 132 extending from both sides of the middle plate 131 towards the bottom of the box 11. Among them, the power board 20 is accommodated between the two mounting plates 132 and fixed on the bottom of the box 11, and the adapter board 30 is fixed on the side of the middle plate 131 facing away from the power board 20, so that the adapter board 30 can be in different spaces in the accommodating cavity 111 with the power board 20 respectively, avoiding the heat generated by the power board 20 directly transmitted to the adapter board 30, and also facilitating the installation of the partition plate 13.

[0050] For example, the mounting plate 132 is bent in one direction from both ends of the middle plate 131, and then the end of the mounting plate 132 away from the middle plate 131 is bent towards the other mounting plate 132 to form a fixing seat 133. Among them, the bottom of the box 11 is provided with a fixing column 114, and the fixing seat 133 is fixed on the fixing column 114. The power board 20 and the adapter board 30 can be electrically connected through a socket assembly, or the power board 20 and the adapter board 30 are connected through a cable assembly.

[0051] In an optional embodiment, the side of the middle plate 131 facing away from the mounting plate 132 is provided with one or more protruding structures 1311. When the number of protruding structures 1311 is one, the area of the protruding structure 1311 is larger than that of a single area when the number of protruding structures 1311 is multiple, so that the end surface of the adapter board 30 can have a certain contact area with the protruding structure 1311, and the end surface of the adapter board 30 abuts on the protruding structure 1311. When the number of protruding structures 1311 is multiple, the protruding structures 1311 are arranged on the middle plate 131 in a spaced manner, and the end surface of the adapter board 30 abuts on the protruding structure 1311, and the adapter board 30 and the middle plate 131 can form an avoiding space, which not only can set electronic devices on the side of the adapter board 30 facing the middle plate 131, but also facilitates heat dissipation of the adapter board 30.

[0052] For example, the protruding structure 1311 comprises a first protrusion 1311a and a second protrusion 1311b, and the first protrusion 1311a and the second protrusion 1311b are arranged on the middle plate 131 in a spaced manner, for supporting the adapter board 30, so that the adapter board 30 and the middle plate 131 can form an avoiding space.

[0053] In an optional embodiment, the intermediate plate 131 is provided with a second accommodating groove 1312, and a adapter plate heat-conducting pad 17 is arranged on the second accommodating groove 1312. The adapter plate 30 abuts against the adapter plate heat-conducting pad 17, so that the heat on the adapter plate 30 can be transmitted from the adapter plate heat-conducting pad 17 to the intermediate plate 131, and then be dissipated through the intermediate plate 131 or be dissipated to the cabinet 11, thereby avoiding the reduction of the service life of the adapter plate 30 due to poor heat dissipation, and effectively avoiding the adapter plate 30 failure caused by the high heat and poor heat dissipation of the adapter plate 30.

[0054] In an optional embodiment, a power supply plate heat-conducting pad 16 is arranged between the bottom of the cabinet 11 and the power supply plate 20. The power supply plate heat-conducting pad 16 is used to conduct the heat generated by the power supply plate 20 to the cabinet 11 for heat dissipation, thereby avoiding the reduction of the service life of the power supply plate 20 due to poor heat dissipation, effectively avoiding the power supply plate 20 failure caused by the high heat and poor heat dissipation of the power supply plate 20, and making the operation and work of the power supply plate 20 more stable and reliable.

[0055] For example, the adapter plate heat-conducting pad 17 and the power supply plate heat-conducting pad 16 are rectangular in the vertical direction of the height of the cabinet 11, i.e., the top view of the adapter plate heat-conducting pad 17 and the power supply plate heat-conducting pad 16 is rectangular, thereby increasing the contact area between the adapter plate 30 and the intermediate plate 131 and the contact area between the power supply plate 20 and the bottom of the cabinet 11, i.e., increasing the heat transfer area.

[0056] In an optional embodiment, the hardware cabinet further comprises a first insulating member 14 arranged between the bottom of the cabinet 11 and the power supply plate 20 to insulate the electrical connection between the power supply plate 20 and the cabinet 11. In an optional embodiment, the hardware cabinet further comprises a second insulating member 15 arranged between the power supply plate 20 and the mounting plate 132 to insulate the electrical connection between the power supply plate 20 and the mounting plate 132.

[0057] In an optional embodiment, as shown in Figures 5 to 10 The hardware cabinet further comprises a protective cover 50 covering the outside of the interface plate 40. The protective cover 50 is provided with at least one hollow part 51 for exposing the second interface module 41. The hollow part 51 can be an opening or a notch on the protective cover 50. The protective cover 50 can protect the electronic devices on the interface plate 40, and the second interface module 41 can be exposed outside the protective cover 50 through the opening or the notch to be electrically connected with various modules of the anesthesia machine, such as a display module, a turbine module, a battery module, a system switch module, and a full-electronic flowmeter module.

[0058] In an alternative embodiment, the interface board 40 is further provided with a first component 43 on the same side as the second interface module 41, the second interface module 41 is arranged along the peripheral side of the interface board 40, the first component 43 is arranged inside the second interface module 41, and the opening or gap is correspondingly arranged on the peripheral side of the protective cover 50, so that the protective cover 50 can be arranged above the first component 43, and the second interface module 41 can be exposed outside the protective cover 50 through the opening or gap.
