[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should also be understood that the terms used in this specification of the present invention are only for describing specific realities. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, 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" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0031] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] According to the first aspect of the present application, the present application provides a hardware box, which includes a box body 11 and a first functional board. The box body 11 is formed with a accommodating cavity 111 having an open end, and the first functional board is installed on the open end to close the accommodating cavity 111. The first functional board and the box body 11 form the outer wall of the accommodating cavity 111, and the accommodating cavity 111 is formed as a closed cavity with 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 board of the present application can realize the function 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 parts sealing method, the processing difficulty of sealing and isolation can be reduced by sealing the open end of the accommodating cavity 111 by the first functional board, and the overall compactness of the hardware box can also be improved.

[0033] The hardware box may include one or more power management circuits, and the one or more power management circuits are located in the closed space of the accommodating cavity 111, so that the power management circuit can be isolated from the external environment. In different embodiments, the power management circuit may be located on the first functional board, or located in the cavity of the accommodating cavity 111, and then electrically connected to the first functional board through wiring or connectors. The power management circuit is located on the first functional board, which means that it is not arranged on the surface of the first functional board facing the outside of the accommodating cavity 111. That is, as long as the power management circuit arranged on the first functional board is not exposed to the external environment of the accommodating cavity 111, it is arranged on the first functional board and located in the closed space of the accommodating cavity 111 as described in this application. When the power management circuit is located in the cavity of the accommodating cavity 111, the hardware box may include a second functional board built into the accommodating cavity 111 and separated from the first functional board, and the power management circuit is arranged on the second functional board; the second functional board is then electrically connected to the first functional board by wiring or connectors.

[0034] The power management circuit can realize voltage conversion of direct current, for example, converting the received direct current of the first voltage into direct current of the second voltage, so as to power other functional modules. When the power management circuit is used to power a functional module whose working power exceeds the power threshold, the design of the power management circuit being enclosed in the accommodating cavity 111 can significantly reduce the risk of fire caused by the high working power of the power management circuit during power supply. The power threshold here can be defined and distinguished by the manufacturer, and this application does not limit it here.

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

[0036] When the functional module is located outside the accommodating cavity and the power management circuit is arranged on the second functional board, a first interface module 42 is further arranged on the side of the first functional board facing the accommodating cavity 111. The second functional board can be electrically connected to 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, so as to supply power to the functional module arranged outside the accommodating cavity 111. The first functional board and the second functional board can be connected through a cable assembly, and the two boards can also be arranged in parallel and electrically connected through a connector.

[0037] When the functional module is located in the accommodating cavity, the power management circuit can be connected to the functional module through other interface modules, or through board wiring, or through a 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 form a plug-in connection with the functional module through the first interface module 42 (the first interface module 42 is arranged toward the inner side of the accommodating cavity 111, and is arranged opposite to the second interface module 41 on both sides of the first functional board), or it can be electrically connected to the functional module through the board wiring of the first functional board. When the power management circuit is arranged on the second functional board in the accommodating cavity, it can form a plug-in connection with the functional module through the third interface module on the second functional board, or it can be electrically connected to the functional module through the cable assembly or the board wiring on the second functional board. When the working power of the functional module exceeds the power threshold, the functional module itself and the power management circuit that supplies power to it are both arranged in the accommodating cavity, which can further realize the oxygen-enriched isolation of the load and the power supply element.

[0038] The hardware box of the present application may also include a third functional board, which is used to convert the received alternating current into direct current of a first voltage, and then output the direct current of the first voltage to the power management circuit, and 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 electronic components for AC / DC conversion and voltage conversion are arranged in the closed space of the hardware box, the safety of the hardware box design of 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 a power management circuit can be an adapter board 30, i.e., a DC-DC conversion board; the first functional board can be an interface board 40, which can be provided with components for cooperating with the adapter board 30 to realize power supply, and can also 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 this direct current into the DC-DC board; the DC-DC board converts this direct current into direct current of different voltages required by various modules of the anesthesia machine; the interface board 40 is connected to the DC-DC board to realize the electrical connection between the DC-DC board and various modules of the anesthesia machine, and the interface board 40 can also realize information interaction with various modules of the anesthesia machine, and various modules of the anesthesia machine include a display module, a turbine module, a battery module, a system switch module, and a fully electronic flow meter module on the anesthesia machine.

[0040] In the following embodiments, the second function board and the third function board are arranged in the hardware box, the first function board has a closed open end, and the power management circuit is arranged on the second function 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 function board, and the third function board and / or the second function board may not be arranged in the hardware box; however, since the hardware box adopts the method of enclosing the power management circuit in the accommodating cavity and adopts the method of enclosing the accommodating cavity with the first function board, the effects of anti-oxygen enrichment and compact design of the present application can be achieved.

[0041] refer to Figures 1 to 9 The hardware box includes a box body 11, a power board 20, an adapter board 30 and an interface board 40, wherein the box body 11 is formed with a receiving chamber 111 having an open end, the power board 20 and the adapter board 30 are both arranged in the receiving chamber 111, and the interface board 40 is installed on the open end to close the receiving chamber 111, so that the electronic components on the power board 20, the adapter board 30 and the interface board 40 that need to be sealed with oxygen-enriched gas can be sealed in the receiving chamber 111, while the electronic components on the interface board 40 that do not need to be sealed with oxygen-enriched gas are exposed outside the receiving chamber 111. The design of the hardware box can not only isolate some electronic components on the power board 20, the adapter board 30 and the interface board 40 from the external oxygen-enriched environment, but also ensure that another part of the electronic components on the interface board 40 can be exposed outside the hardware box, so as to transmit electric energy or information to the anesthesia machine.

[0042] In the prior art, the power board 20, adapter board 30, interface board 40 and gas circuit components of the loop system inside the anesthesia machine are scattered inside the workbench or inside the main unit of the anesthesia machine, and no system module is formed; at the same time, there is no oxygen-enriched seal between the power board 20, adapter board 30, interface board 40 and the gas circuit components, which easily causes the power board 20, adapter board 30 and interface board 40 to catch fire. The present application integrates the power board 20, adapter board 30 and interface board 40 in a hardware box, which not only facilitates the installation of the power board 20, adapter board 30 and interface board 40, but also facilitates the subsequent maintenance of the power board 20, adapter board 30 and interface board 40; at the same time, the power board 20, adapter board 30 and interface board 40 can be isolated from the oxygen-enriched environment where the gas circuit components are located, thereby playing a fire prevention role.

[0043] In an optional embodiment, the interface board 40 includes a first interface module 42 and a second interface module 41, the power board 20 and the adapter board 30 are electrically connected to the first interface module 42 in sequence, and the second interface module 41 is electrically connected to 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 setting position of the first interface module 42 can achieve oxygen-enriched isolation of the electronic components 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 11, so that the interface board 40 can be connected to each module of the anesthesia machine through the second interface module 41, and is used to transmit electrical energy or information to the anesthesia machine and each module, that is, the second interface module 41 can be used as an electrical socket, and can also be used 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 fully electronic flow meter module.

[0044] Exemplarily, 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, so that the electronic components on the power board 20, the adapter board 30 and the interface board 40 that require oxygen-enriched sealing are sealed in the accommodating cavity 111, and the electronic components on the interface board 40 that do not require oxygen-enriched sealing face the outside of the accommodating cavity 111. The electronic components on the interface board 40 that do not require oxygen-enriched sealing include but are not limited to electronic components such as sockets and buzzers.

[0045] Exemplarily, the power board 20 and the adapter board 30 are spaced apart on the bottom of the accommodating cavity 111; or the power board 20 and the adapter board 30 are spaced apart 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 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 spaced apart from the bottom of the accommodating cavity 111 toward the open end of the accommodating cavity 111.

[0046] After adopting the above technical solution, since 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 components that need oxygen-enriched sealing are arranged on the side of the interface board 40 facing the accommodating cavity 111, and the electronic components that do not need oxygen-enriched sealing are 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 to the adapter board 30 and sealed in the accommodating cavity 111, and the second interface module 41 can transmit electrical energy or signals to each module of the anesthesia machine to realize ventilation control of each module of the anesthesia machine. Compared with setting the first interface module 42 and the second interface module 41 in different boards, the present application can not only reduce the space occupied by 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, if Figures 4 to 7 As shown, the hardware box also includes a partition plate 13, wherein the partition plate 13 is arranged in the accommodating cavity 111, and the adapter plate 30 is installed on the partition plate 13, thereby forming a layered layout relative to the power board 20, which is beneficial to the overall miniaturization design of the hardware box.

[0048] At least part of the partition plate can be arranged to be spaced apart from the inner wall of the box body, and the accommodating chamber 111 is divided into two parts, and the power board and the adapter board are respectively installed in the two spaces separated by the partition plate (the two spaces can be closed spaces, or can be two parts separated by the partition plate). When the adapter board is installed on the partition plate and the power board is directly or indirectly installed on the inner wall of the box body, a layered layout of multiple boards can be formed inside the box body of the hardware box. Exemplarily, 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 board 20 can be set below the partition plate 13 and the adapter plate 30 can be set above the partition plate 13; or, the partition plate 13 is perpendicular to the bottom of the accommodating cavity 111, the power board 20 is set on one side of the partition plate 13, and the adapter plate 30 is set on the other side of the partition plate 13; or, the partition plate 13 is set at an angle to the bottom of the accommodating cavity 111, and the power board 20 and the adapter plate 30 are distributed on both sides of the partition plate 13, which is not limited in the present application.

[0049] In an optional embodiment, the partition plate 13 includes a middle plate 131 and mounting plates 132 extending from both sides of the middle plate 131 toward the bottom of the box body 11. The power board 20 is accommodated between the two mounting plates 132 and fixed to the bottom of the box body 11, and the adapter plate 30 is fixed on the side of the middle plate 131 facing away from the power board 20, so that the adapter plate 30 and the power board 20 can be in different spaces in the accommodating cavity 111, respectively, to prevent the heat generated by the power board 20 from being directly transferred to the adapter plate 30, and also facilitate the installation of the partition plate 13.

[0050] Exemplarily, the mounting plate 132 is formed by bending the two ends of the middle plate 131 in one direction, and then bending the end of the mounting plate 132 away from the middle plate 131 toward the other mounting plate 132 to form a fixing seat 133. A fixing column 114 is provided at the bottom of the box body 11, 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 can be connected through a cable assembly.

[0051] In an optional embodiment, one or more protruding structures 1311 are provided on the side of the middle plate 131 facing away from the mounting plate 132, wherein when there is one protruding structure 1311, the area of ​​the protruding structure 1311 is larger than the single area when there are multiple protruding structures 1311, so that the end surface of the adapter plate 30 can have a certain contact area with the protruding structure 1311, and the end surface of the adapter plate 30 abuts on the protruding structure 1311. When there are multiple protruding structures 1311, the protruding structures 1311 are arranged on the middle plate 131 at intervals, and the end surface of the adapter plate 30 abuts on the protruding structure 1311, so that an avoidance space can be formed between the adapter plate 30 and the middle plate 131, which not only allows electronic devices to be arranged on the side of the adapter plate 30 facing the middle plate 131, but also facilitates the heat dissipation of the adapter plate 30.

[0052] Exemplarily, the protrusion structure 1311 includes a first protrusion 1311a and a second protrusion 1311b, and the first protrusion 1311a and the second protrusion 1311b are spaced apart on the middle plate 131 to support the adapter plate 30 so that an escape space can be formed between the adapter plate 30 and the middle plate 131.

[0053] In an optional embodiment, a second accommodating groove 1312 is provided on the middle plate 131, and an adapter plate thermal pad 17 is provided on the second accommodating groove 1312. The adapter plate 30 abuts against the adapter plate thermal pad 17 so that the heat on the adapter plate 30 can be transferred from the adapter plate thermal pad 17 to the middle plate 131, and then dissipated through the middle plate 131 or transferred to the box body 11 for heat dissipation, thereby avoiding the adapter plate 30 from having a reduced service life due to poor heat dissipation, and effectively avoiding the adapter plate 30 from having too much heat or poor heat dissipation, thereby causing the adapter plate 30 to fail.

[0054] In an optional embodiment, a power board thermal pad 16 is provided between the bottom of the box body 11 and the power board 20. The power board thermal pad 16 is used to conduct the heat generated by the power board 20 to the box body 11 for heat dissipation, thereby avoiding that the service life of the power board 20 is reduced due to poor heat dissipation. It can effectively avoid that the power board 20 fails due to excessive heat and poor heat dissipation, so that the operation and work of the power board 20 will be more stable and reliable.

[0055] Exemplarily, the cross-section of the adapter board thermal pad 17 and the power board thermal pad 16 along the height direction perpendicular to the box body 11 is rectangular, that is, the top view of the adapter board thermal pad 17 and the power board thermal pad 16 is rectangular, thereby increasing the contact area between the adapter board 30 and the middle plate 131, and the power board 20 and the bottom of the box body 11, that is, increasing the heat transfer area.

[0056] In an optional embodiment, the hardware box further includes a first insulating member 14, which is disposed between the bottom of the box body 11 and the power board 20 to isolate the electrical connection between the power board 20 and the box body 11. In an optional embodiment, the hardware box further includes a second insulating member 15, which is disposed between the power board 20 and the mounting plate 132 to isolate the electrical connection between the power board 20 and the mounting plate 132.

[0076] In an optional embodiment, the box body 11 is made of metal material to prevent the electronic devices in the box body 11 from radiating outward and interfering with external equipment, thereby effectively shielding the electromagnetic radiation generated by the power board 20, the adapter board 30 and the interface board 40 when they are working.
