Description

Technical Field

[0001] This invention relates to the field of medical devices, and more particularly to a ventilation device main unit and a ventilation device. Background Technology

[0002] To facilitate the assembly and testing of core components, existing ventilation equipment integrates these components into a core support frame, forming a core module which is then installed inside the housing. While this design simplifies assembly and testing, the use of a core support frame results in a relatively large overall weight for the ventilation equipment unit. Furthermore, the internal space is not efficiently utilized, leading to a bulky unit that fails to meet the demands for lightweight and miniaturized ventilation equipment in emergency and transport settings. Summary of the Invention

[0003] In view of this, the present invention proposes a ventilation device main unit and a ventilation device.

[0004] The ventilation device main unit according to the first aspect of the present invention includes:

[0005] The housing assembly includes a back plate, a first side plate and a second side plate respectively disposed on opposite sides of the back plate;

[0006] An oxygen control component is disposed inside the housing assembly, and the oxygen control component is used to connect to an oxygen supply device;

[0007] A turbine assembly, located inside the housing assembly, receives oxygen output from the oxygen control assembly;

[0008] A gas output assembly, disposed within the housing assembly, is used to receive gas output from the turbine assembly and to connect to an inspiratory branch for delivering gas to a patient; and

[0009] A pressure monitoring component is disposed inside the housing assembly, and the pressure monitoring component is used to communicate with the gas output component to monitor relevant parameters of the input and / or output gas of the gas output component;

[0010] The housing assembly further includes a first support member that divides the internal space of the housing assembly into an upper region and a bottom region.

[0011] The gas output component, oxygen control component, pressure monitoring component, and turbine component are disposed in the upper region, and at least one of them is fixed to the housing component;

[0012] The bottom area is used to house the battery assembly.

[0013] The ventilation device proposed in the second aspect of the present invention includes an intake branch and the above-mentioned ventilation device main unit, wherein the intake branch is connected to the gas output component.

[0014] As can be seen from the above technical solution, the ventilation equipment main unit proposed in the first aspect of the present invention divides the internal space of the housing assembly into an upper region and a bottom region by setting a first supporting component. The gas output component, oxygen control component, pressure monitoring component, and turbine component are located in the upper region, while the bottom region is used to accommodate the battery component. In this way, the first supporting component separates the chamber where the gas output component, oxygen control component, and pressure monitoring component are installed from the chamber where the battery component is installed, which is beneficial for the protection between the two components, reduces the mutual influence between the two components, and improves safety performance. Secondly, by setting the bottom region to accommodate the battery component, the center of gravity of the ventilation equipment main unit can be lowered, allowing the ventilation equipment main unit to be placed stably on the bearing surface. In addition, by setting at least one of the gas output component, oxygen control component, pressure monitoring component, and turbine component to be fixed to the housing assembly, it is not necessary to fix these four components to the same bracket and then assemble them onto the housing assembly. This eliminates the need for a large and heavy bracket, which can effectively reduce the overall weight of the ventilation equipment main unit, making the ventilation equipment main unit lightweight and reducing its size.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 6 As shown, an embodiment of the present invention provides a ventilation device main unit 100, which includes a housing assembly 10, a panel 14 connected to the housing assembly 10, a gas output assembly 20, a pressure monitoring assembly 30, an oxygen control assembly 40, and a turbine assembly 104. The housing assembly 10 includes a back plate 11, a first side plate 12, and a second side plate 13, with the first side plate 12 and the second side plate 13 respectively disposed on opposite sides of the back plate 11. The panel 14 is disposed opposite to the back plate 11. The oxygen control assembly 40 is disposed inside the housing assembly 10 and is used to connect to an oxygen supply device. The turbine assembly 104 is disposed inside the housing assembly 10 to receive oxygen output from the oxygen control assembly 40. The gas output assembly 20 is disposed in the housing assembly 10 and is used to receive gas output from the turbine assembly 104 and to connect to an inspiratory branch for delivering gas to the patient. The pressure monitoring component 30 is located inside the housing component 10. The pressure monitoring component 30 is used to communicate with the gas output component 20 to monitor relevant parameters of the input and / or output gas of the gas output component 20. The relevant parameters of the gas output by the gas output component 20 monitored by the pressure monitoring component 30 include, but are not limited to, monitoring airway pressure and controlling PEEP (positive end-expiratory pressure).

[0029] The housing assembly 10 also includes a first support member 60, which divides the internal space of the housing assembly 10 into an upper region A1 and a bottom region A2. The gas output assembly 20, the oxygen control assembly 40, the pressure monitoring assembly 30, and the turbine assembly 104 are disposed in the upper region A1, and at least one of them is fixed to the housing assembly 10. The bottom region A2 is used to accommodate the battery assembly.

[0030] It should be noted that the gas output assembly 20, oxygen control assembly 40, pressure monitoring assembly 30, and turbine assembly 104 are disposed in the upper region A1, and at least one of them is fixed to the housing assembly 10. For example, one of them may be fixed to the first side plate 12, and the others may be fixed to the first support member 60. For example, in one embodiment, the gas output assembly 20 is fixed to the first side plate 12, and the oxygen control assembly 40, pressure monitoring assembly 30, and turbine assembly 104 are fixed to the first support member 60.

[0031] The at least one component being fixed to the housing assembly 10 can be: one component is fixed to the housing assembly 10, while the other two are fixed to the housing assembly 10 via the same bracket; or the other three are fixed to the housing assembly 10 via the same bracket. The at least one component being fixed to the housing assembly 10 can also be: two components are each fixed to the housing assembly 10, while the other two are fixed to the housing assembly 10 via, for example, the same bracket. The at least one component being fixed to the housing assembly 10 can also be: all four components are fixed to the housing assembly 10.

[0032] Throughout this application, the gas output component 20, oxygen control component 40, pressure monitoring component 30, and turbine component 104 are described as "one of," "two of," or "all four" fixed to the housing component 10. The term "fixed" emphasizes that they are individually connected to the housing component, meaning they are not connected to the housing component 10 via a common bulk support. This "individual connection" can mean directly fastening each component to the housing component 10 with fasteners, or it can mean distributing and fixing them to the housing component 10 using small partitions, sheet metal parts, connecting columns, brackets, or other supporting components. The specific method depends on the actual design requirements. Since it eliminates the need to fix these four components to the same support before assembling them onto the housing component 10, a large and heavy support is eliminated, allowing the ventilation equipment main unit 100 to be smaller and lighter.

[0033] The ventilation equipment main unit 100 proposed in this embodiment of the invention divides the internal space of the housing assembly 10 into an upper region A1 and a bottom region A2 by setting a first support member 60. The gas output assembly 20, oxygen control assembly 40, pressure monitoring assembly 30, and turbine assembly 104 are arranged in the upper region A1, and the bottom region A2 is used to accommodate the battery assembly. In this way, the first support member 60 separates the chamber where the gas output assembly 20, oxygen control assembly 40, and pressure monitoring assembly 30 are installed from the chamber where the battery assembly 50 is installed, which is beneficial for the protection between the two parts of the assembly, reduces the mutual influence between the two parts of the assembly, and improves the safety performance. Secondly, by setting the bottom region A2 to accommodate the battery assembly, the center of gravity of the ventilation equipment main unit 100 can be lowered when the bottom region A2 accommodates the battery assembly, so that the ventilation equipment main unit 100 can be placed stably on the support surface. Furthermore, by fixing at least one of the gas output component 20, oxygen control component 40, pressure monitoring component 30, and turbine component 104 to the housing component 10, it is not necessary to fix these four components to the same bracket and then assemble them onto the housing component 10. This eliminates the need for a bulky and heavy bracket, effectively reducing the overall weight of the ventilation equipment main unit 100, thus achieving lightweighting of the ventilation equipment main unit 100 and reducing its size.

[0034] In one embodiment, the first support member 60 is fixedly horizontally disposed between the first side plate 12 and the second side plate 13. In a preferred embodiment, the first support member 60 is integrally formed with the first side plate 12 and the second side plate 13 of the housing assembly 10 by means of a connector or integral molding.

[0035] In one embodiment, the first support member 60 has a hollow structure. This embodiment reduces the weight of the first support member 60, thereby reducing the weight of the ventilation equipment main unit 100, which is beneficial for achieving lightweight design of the ventilation equipment main unit 100. It should be noted that the design is not limited to the above-described configuration. For example, in another embodiment, the first support member 60 can be configured as a ring, which can significantly reduce the weight of the first support member 60. Of course, the first support member 60 can also be configured as a single, continuous component, depending on the actual design requirements.

[0036] In one embodiment, the first support member 60 is connected to the first side plate 12, the second side plate 13, and the back plate 11. That is, the first support member 60 is separately configured relative to the first side plate 12, the second side plate 13, and the back plate 11, and is connected to them via a mechanical structure. Of course, it is also possible for the first support member 60 to be integrally formed with the first side plate 12, the second side plate 13, and the back plate 11.

[0037] In one embodiment, the first support member 60 is connected to the first side plate 12 and the back plate 11. That is, the first support member 60 is separately disposed from the first side plate 12 and the back plate 11, and the first support member 60 is connected to the first side plate 12 and the back plate 11 through a mechanical structure. Of course, it is also possible for the first support member 60 to be integrally formed with the first side plate 12 and the back plate 11.

[0038] In one embodiment, the first support member 60 is connected to the second side plate 13 and the back plate 11. That is, the first support member 60 is separately disposed from the second side plate 13 and the back plate 11, and the first support member 60 is connected to the second side plate 13 and the back plate 11 through a mechanical structure. Of course, it is also possible for the first support member 60 to be integrally formed with the second side plate 13 and the back plate 11.

[0039] In one embodiment, the oxygen control assembly 40 includes a proportional valve and a first flow sensor, wherein the proportional valve is used to regulate the oxygen flow rate and the first flow sensor is used to monitor the oxygen flow rate.

[0040] In one embodiment, the gas output component 20 includes a release valve and a second flow sensor. When the pressure of the output gas is greater than a preset value, the release valve opens to release part of the gas to balance the pressure. The second flow sensor is used to monitor the flow rate of the output gas.

[0041] like Figure 1 As shown, in one embodiment, the ventilation device main unit 100 also includes a display screen 102 disposed on the panel 14, the display screen 102 being used to display at least the waveform of breathing and monitoring parameters.

[0042] In one embodiment, the gas output assembly 20, the oxygen control assembly 40, the pressure monitoring assembly 30, and the turbine assembly 104 are arranged independently of each other. The gas output assembly 20 is mounted on the back plate 11 or the first side plate 12 and extends from the first side plate 12 to the outside of the housing assembly 10.

[0043] like Figure 4 and Figure 5 As shown, in one embodiment, the pressure monitoring component 30 is mounted on the first support member 60. It should be noted that the pressure monitoring component 30 is not limited to being mounted on the first support member 60. For example, in some other embodiments, the pressure monitoring component 30 may be mounted on the back plate 11 or the first side plate 12.

[0044] like Figure 4 and Figure 5As shown, in one embodiment, the ventilation device main unit 100 further includes an interface component F for connecting the inhalation branch and the pressure monitoring component 30. The pressure monitoring component 30 is mounted on the back panel 11, and the interface component F is connected to the first side panel 12. In this embodiment, by separating the interface component F50 and the pressure monitoring component 30, the positions of the interface component F50 and the pressure monitoring component 30 can be flexibly arranged, thereby making reasonable use of the internal space of the housing component 10 to reduce the size of the ventilation device main unit 100. Not limited to the above embodiment, for example, in another embodiment, the pressure monitoring component 30 is mounted on the first side panel 12, and the interface component F is connected to the panel 14.

[0045] In one embodiment, the pressure monitoring component 30 is connected to the turbine assembly 104 to monitor relevant parameters of the gas output from the turbine assembly 104.

[0046] In another embodiment, the pressure monitoring component 30 is connected to the interface component F to monitor relevant parameters of the gas input to the interface component F.

[0047] like Figure 4 and Figure 5 As shown, in one embodiment, the oxygen control assembly 40 is mounted on the first support member 60. It should be noted that the oxygen control assembly 40 is not limited to being mounted on the first support member 60. For example, in some other embodiments, the oxygen control assembly 40 may be mounted on the back panel 11 or the first side panel 12.

[0048] like Figure 3 and Figure 5 As shown, in one embodiment, the ventilation equipment main unit 100 further includes a second support member 70, which is horizontally disposed between the first side plate 12 and the second side plate 13 to divide the upper region A1 into a top region A11 and a middle region A12. The gas output component 20, the oxygen control component 40, and the pressure monitoring component 30 are located in the middle region A12. The ventilation equipment main unit 100 also includes a control board 80, which is located in the top region A11. In this embodiment, by placing the control board 80 in the top region A11, the control board 80 generates more heat when it is working, which heats the surrounding air. The hot air is lighter and will stay in the top region A11, thereby reducing the impact of the hot air on the gas output component 20, the oxygen control component 40, and the pressure monitoring component 30. In addition, by setting the second support member 70 to separate the chamber where the gas output component 20, the oxygen control component 40, and the pressure monitoring component 30 are installed from the chamber where the control board 80 is installed, it is beneficial for the protection between the two components, reduces the mutual influence between the two components, and improves safety performance.

[0049] In one embodiment, the control panel 80 is laid flat in the upper region A1, thereby reducing the space occupied by the control panel 80 and making the overall height of the ventilation equipment main unit 100 lower.

[0050] The control board 80 involved in this embodiment is one of the PCB boards of a medical ventilation device. The control board 80 can realize ventilation control of the medical ventilation device. For example, it can control the turbine assembly 104 and receive pressure and / or flow rate monitored by various sensors. Optionally, it can also integrate a power supply module. This application does not limit the control that the control board 80 can realize.

[0051] like Figure 3 and Figure 5 As shown, in one embodiment, the ventilation equipment main unit 100 further includes a support assembly 90 for supporting the second support member 70, the support assembly 90 being installed between the first support member 60 and the second support member 70. In this embodiment, by providing the support assembly 90 to form a support between the first support member 60 and the second support member 70, the support strength for the control panel 80 can be improved. The support assembly 90 can be, but is not limited to, a support assembly 90 made of metal. Understandably, the support assembly 90 can also increase the strength of the entire housing assembly 10, improving its impact resistance. When the ventilation equipment main unit 100 is accidentally dropped, it can reduce the deformation of the housing assembly 10 under impact force, thereby providing better protection for the gas output assembly 20, the oxygen control assembly 40, and the pressure monitoring assembly 30.

[0052] In one embodiment, the support assembly 90 includes a crossbeam 91 and a support rod 92, both of which may be elongated. The crossbeam 91 is connected to the back plate 11. The support rod 92 connects the crossbeam 91 to the first support member 60. A second support member 70 is connected to and supported by the crossbeam 91, and a control plate 80 is mounted on the second support member 70.

[0053] like Figure 3 and Figure 5As shown, in one embodiment, the ventilation device main unit 100 further includes a reinforcing member 101, which is located in the top region A11 and connected to the second support member 70. The control plate 80 is located in the area enclosed by the reinforcing member 101 and the second support member 70. Specifically, the reinforcing member 101 includes a reinforcing plate 1011 and a column 1012 extending from the reinforcing plate 1011 toward the second support member 70. The control plate 80 has a through mounting hole 81, through which the column 1012 passes and is connected to the second support member 70. The control plate 80 is sandwiched between the reinforcing plate 1012 and the second support member 70. In this embodiment, the control plate 80 is fixed by clamping it between the reinforcing plate 1012 and the second support member 70. Compared with the existing method of using screws to fasten the control plate 80, the fixing method of the control plate 80 proposed in this embodiment is not affected by the stress of screw connection, which can reduce the occurrence of circuit breakage damage caused by stress deformation of the control plate 80 during assembly, thereby improving the yield rate of the equipment.

[0054] Furthermore, in this embodiment, when the ventilation equipment main unit 100 accidentally falls to the ground top-down, the reinforcing member 101 can protect the control board 80 and prevent damage to it. The reinforcing member 101 can be, but is not limited to, a reinforcing member 101 made of metal.

[0055] like Figure 5 As shown, in one embodiment, the ventilation device main unit 100 further includes a physiological parameter acquisition component, which is used to connect to a physiological parameter sensor and acquire the patient's blood oxygen parameters through the physiological parameter sensor. The physiological parameter acquisition component includes a physiological parameter acquisition interface 103, wherein the physiological parameter acquisition interface 103 is connected to the first side plate 12 or the front panel 14.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment, the oxygen control assembly 40 and the pressure monitoring assembly 30 are located below the gas output assembly 20. In this embodiment, by making reasonable use of the space in the height direction of the housing assembly 10, the thickness of the housing assembly 10 can be reduced.

[0057] In one embodiment, the oxygen control component 40 and the pressure monitoring component 30 are arranged sequentially from the back panel 11 to the front panel 14. In some embodiments, to facilitate viewing on the display screen 102, the front panel 14 is tilted, making the ventilation device main unit 100 narrower at the top and wider at the bottom. In this embodiment, by positioning the oxygen control component 40 and the pressure monitoring component 30 below the gas output component 20, and arranging them sequentially from the back panel 11 to the front panel 14, the pressure monitoring component 30, the oxygen control component 40, and the gas output component 20 also exhibit a narrower-than-wider arrangement, thereby making efficient use of the internal space of the housing component 10 and enabling the ventilation device main unit 100 to be miniaturized.

[0058] like Figures 2 to 4 As shown, in one embodiment, the housing assembly 10 includes a first region B1, a second region B2, and a third region B3 arranged sequentially along the length YY from the second side plate 13 to the first side plate 12. The turbine assembly 104 is disposed inside the housing assembly 10 and located in the second region B2, while the gas output assembly 20, the oxygen control assembly 40, and the pressure monitoring assembly 30 are located in the third region B3. In this embodiment, the gas output assembly 20 and the pressure monitoring assembly 30 are located on the same side within the housing assembly 10, and their corresponding interfaces can be located on the same side plate, facilitating subsequent pipeline connections.

[0059] like Figure 3 and Figure 4 As shown, in one embodiment, the ventilation device main unit 100 further includes an oxygen interface component 105, which is located in the first region B1.

[0060] In one embodiment, the oxygen interface assembly 105 is connected to the oxygen control assembly 40 via a pipeline P. The oxygen control assembly 40 is connected to the turbine assembly 104. The oxygen interface assembly 105 is used to connect to an oxygen supply device to allow the oxygen supplied by the oxygen supply device to flow into the oxygen control assembly 40. The oxygen control assembly 40 then flows the oxygen into the turbine assembly 104.

[0061] In one embodiment, the oxygen interface assembly 105 is mounted on the second side plate 13. The pipeline P can be, but is not limited to, a PU pipe. In this embodiment, by separating the oxygen interface assembly 105 and the oxygen control assembly 40, the positions of the oxygen interface assembly 105 and the oxygen control assembly 40 can be flexibly arranged, thereby making reasonable use of the internal space of the housing assembly 10 and reducing the size of the ventilation equipment main unit 100.

[0062] like Figure 4As shown, in one embodiment, the ventilation device host 100 further includes an oxygen monitoring module S, which is connected to the gas output component 20. The oxygen monitoring module S is used to detect the oxygen content in the gas output by the gas output component 20.

[0063] In one embodiment, the ventilation device main unit 100 further includes a battery assembly 50 located in the bottom region A2.

[0064] In one embodiment, both the bottom region A2 and the battery assembly 50 are flat, with the battery assembly 50 laid flat on the bottom region A2. This implementation helps to lower the center of gravity of the ventilation equipment main unit 100, making the ventilation equipment main unit 100 more stable, and also reduces the overall height of the ventilation equipment main unit 100, achieving miniaturization requirements.

[0065] like Figure 6 As shown, in one embodiment, the back panel 11 is provided with an assembly port 111, which communicates with the bottom region A2. The battery assembly 50 is installed into the bottom region A2 through the assembly port 111. The ventilation device main unit 100 also includes a clamping assembly 106, which is movably mounted on the back panel 11 and is used to clamp the battery assembly 50 within the bottom region A2. In this embodiment, by providing the clamping assembly 106 to clamp the battery assembly 50 within the bottom region A2, it is possible to avoid the battery being damaged and / or falling out of the ventilation device main unit 100 due to vibration and impact during harsh transportation environments.

[0066] like Figures 6 to 9 As shown, in one embodiment, the assembly port 111 includes a first side disposed along the vertical direction and a second side opposite to the first side. The first side of the assembly port 111 is provided with a first assembly portion C1, and the second side of the assembly port 111 is provided with a protrusion C2. The clamping assembly 106 includes a cover plate assembly 1061, a locking tongue 1062, and an elastic member 1063. The cover plate assembly 1061 is provided with a second assembly portion C3, which is used to connect with the first assembly portion C1. The locking tongue 1062 is movably mounted on the cover plate assembly 1061 along the vertical direction shown in the figure. The locking tongue 1062 includes a first end and a second end. The first end of the locking tongue 1062 is used to engage with the protrusion C2 so that the clamping assembly 106 is engaged with the protrusion C2. An elastic element 1063 is disposed inside the cover plate assembly 1061. The elastic element 1063 abuts against the second end of the cover plate assembly 1061 and the latch 1062. The elastic element 1063 provides a restoring force to keep the latch 1062 engaged with the protrusion C2. The cover plate assembly 1061 has a handle position D, and a portion of the latch 1062 is located in or exposed in the handle position D. By pressing the portion of the latch 1062 located in the handle position D, the latch 1062 can be driven to disengage from the protrusion C2.

[0067] In one embodiment, the latch 1062 includes a first side and a second side opposite to the first side, with the first side of the latch 1062 facing the battery assembly 50. The first side of the first end of the latch 1062 has a first inclined surface 1064, which extends obliquely from the end of the first end of the latch 1062 toward the first side of the latch 1062, that is, it extends obliquely downward from the end of the first end of the latch 1062 toward the battery assembly 50. In this embodiment, when an operator presses the second side of the cover assembly 1061, the protrusion C2 abuts against the first inclined surface 1064, and the force exerted by the protrusion C2 on the first inclined surface 1064 pushes the latch 1062 downward until the protrusion C2 passes over the latch 1062 and engages with the second side of the latch 1062, thus completing the installation of the second side of the cover assembly 1061. This embodiment makes the installation of the cover assembly 1061 convenient.

[0068] It should be noted that the first side of the latch 1062 may not have the first inclined surface 1064. As mentioned above, the cover plate assembly 1061 is provided with a handle position D. When installing the cover plate assembly 1061, the operator can press the latch 1062 down through the handle position D to move the cover plate assembly 1061 into place, and then release the latch 1062. Under the action of the elastic element 1063, the latch 1062 moves upward until the protrusion C2 is locked on the second side of the latch 1062.

[0069] In one embodiment, a second inclined surface 1065 is provided on the second side of the first end of the latch 1062. The second inclined surface 1065 extends obliquely from the end of the first end of the latch 1062 toward the second side of the latch 1062. In this embodiment, by providing the second inclined surface 1065, the protrusion C2 acting on the second inclined surface 1065 will always maintain a component force pressing the cover assembly 1061 against the battery assembly 50, thereby ensuring that the cover assembly 1061 remains stable and does not wobble. Of course, it is also possible not to provide the second inclined surface 1065 on the second side of the latch 1062, depending on the actual design requirements.

[0070] In one embodiment, one of the first assembly part C1 and the second assembly part C3 is a groove, and the other of the first assembly part C1 and the second assembly part C3 is a protrusion, which is embedded in the groove. It should be noted that the positions of the groove and the protrusion can be interchanged, that is, the first assembly part C1 can be a protrusion and the second assembly part C3 can be a groove, depending on the actual design requirements.

[0071] The installation and disassembly process of the clamping assembly 106 proposed in the above embodiment is as follows: When installing the clamping assembly 106, the operator first inserts the protrusion into the groove, and then presses the second side of the cover plate assembly 1061. The first inclined surface 1064 of the first end of the latch 1062 abuts against the protrusion C2. The force exerted by the protrusion C2 on the first inclined surface 1064 pushes the latch 1062 downward until the protrusion C2 passes over the first end of the latch 1062 and is locked on the second side of the latch 1062, thus completing the installation of the clamping assembly 106. Of course, the operator can also press the latch 1062 to make it move downward, then press the second side of the cover plate assembly 1061 into place, so that the protrusion C2 is located on the second side of the latch 1062, and then release the latch 1062. The latch 1062 moves upward under the push of the elastic member 1063 until the protrusion C2 is locked on the second side of the latch 1062. When it is necessary to remove the clamping component 106, the operator inserts their finger into the latch position D and presses the locking tongue 1062, causing the locking tongue 1062 to disengage from the protrusion C2, and then the clamping component 106 can be removed.

[0072] It should be noted that the clamping component 106 is not limited to the above-described configuration. For example, in another embodiment, such as... Figure 10 and Figure 11 As shown, the clamping assembly 106 includes a clamping member 1066, which includes a first end and a second end opposite to the first end. The first end of the clamping member 1066 is provided with a second assembly part C3, and the second end of the clamping member 1066 is provided with a latching part C4. The second assembly part C3 is rotatably connected to the first assembly part C1, and the latching part C4 is engaged with the protrusion C2.

[0073] In one embodiment, the second end of the clamping member 1066 includes a spring arm 1067, which may include a bent portion connected to the main body of the clamping member 1066. When the spring arm 1067 is subjected to compressive force, it deforms toward the first end of the clamping member 1066; after the compressive force is removed, the spring arm 1067 returns to its original position. The latching portion C4 includes a first protrusion C41 and a second protrusion C42 spaced apart from the first protrusion C41, and a protrusion C2 is engaged between the first protrusion C41 and the second protrusion C42.

[0074] like Figure 11As shown, in one embodiment, the clamping member 1066 includes a first side and a second side opposite to the first side, with the first side of the clamping member 1066 facing the battery assembly 50. The clamping member 1066 also includes a shock absorber 1068, which is disposed on the first side of the clamping member 1066 and abuts against the battery assembly 50. In this embodiment, the shock absorber 1068 can clamp the battery assembly 50 while providing shock absorption and cushioning for the battery assembly 50. The shock absorber 1068 can be, but is not limited to, sponge or PE (polyethylene) foam.

[0075] In one embodiment, the clamping assembly 106 further includes a cover plate assembly 1061, which is detachably connected to the housing assembly 10 for sealing the assembly opening 111.

[0076] The installation and disassembly process of the clamping assembly 106 proposed in the above embodiment is as follows: When installing the clamping assembly 106, the operator pushes the second end of the clamping member 1066 until the protrusion C2 is engaged between the first protrusion C41 and the second protrusion C42, and then the cover plate assembly 1061 is placed over the assembly opening 111. When it is necessary to disassemble the clamping assembly 106, the operator removes the cover plate assembly 1061, then presses the spring arm 1067 to disengage the first protrusion C41 and the second protrusion C42 from the protrusion C2, and then the clamping member 1066 is rotated open.

[0077] like Figure 3 and Figure 6 As shown, in one embodiment, the housing assembly 10 is provided with a first vent 15 and a second vent 16. The ventilation device main unit 100 also includes a fan assembly 107, which is located inside the housing assembly 10. The fan assembly 107 drives gas to enter the housing assembly 10 through the first vent 15 and then exit through the second vent 16. The fan assembly 107 is mounted on the housing assembly 10 and faces the second vent 16. In this embodiment, by providing the fan assembly 107 to dissipate heat from the heat-generating components inside the housing assembly 10, the impact of the temperature generated by the heat-generating components during operation on surrounding components can be reduced.

[0078] like Figures 2 to 4 , Figure 6As shown, in one embodiment, the fan assembly 107 and the second vent 16 are located in the first region B1, and the first vent 15 is located in the third region B3. This implementation extends the airflow path after entering the housing assembly 10, thereby carrying away more heat from inside the housing assembly 10 and achieving better heat dissipation. Furthermore, this implementation has a reasonable component layout; the gas output assembly 20 and the pressure monitoring assembly 30 are located on the same side of the housing assembly 10, and their interfaces can be located on the same side plate, facilitating subsequent pipe connections. Moreover, the turbine assembly 104 is located between the air inlet 15 and the air outlet 16. Airflow entering the housing assembly 10 from the air inlet 15 passes through the turbine assembly 104 and is then discharged from the air outlet 16, providing good heat dissipation for the turbine assembly 104.

[0079] like Figures 2 to 4 , Figure 6 As shown, in one embodiment, the first vent 15 is an air inlet 15, located near the bottom of the housing assembly 10, and the second vent 16 is an air outlet 16, located near the top of the housing assembly 10. When the fan assembly 107 is running, airflow enters the interior of the housing assembly 10 through the air inlet 15, flows through the pressure monitoring assembly 30 and the turbine assembly 104, and is then discharged from the air outlet 16. According to physical principles, hot air has a lower density and will automatically rise. In this embodiment, by placing the air outlet 16 near the top of the housing assembly 10, the hot airflow can be directly discharged from the air outlet 16 when it automatically flows to the top of the housing assembly 10, avoiding the hot airflow from flowing inside the housing assembly 10 and achieving a better heat dissipation effect.

[0080] In addition, it should be noted that, as mentioned above, the control board 80 of the ventilation equipment main unit 100 is located in the top area A11 of the housing assembly 10. In this way, the heat generated by the control board 80 during operation can be directly discharged from the air outlet 16, thereby preventing the heat generated by the control board 80 during operation from flowing to other areas and affecting other components.

[0081] like Figure 6 As shown, in one embodiment, the air inlet 15 is disposed on the back plate 11, and the air outlet 16 can also be disposed on the back plate 11 and diagonally opposite to the air inlet 15. In another embodiment, the air inlet 15 is disposed on the back plate 11, and the air outlet 16 is disposed on the second side plate 13 or on the same side as the second side plate 13, and the air outlet 16 is diagonally opposite to the air inlet 15. With this implementation, the flow path of the airflow after entering the housing assembly 10 can be extended, thereby carrying away more heat from the inside of the housing assembly 10 and achieving a better heat dissipation effect. It should be noted that the air inlet 15 and the air outlet 16 are not limited to being disposed on the back plate 11 of the housing assembly 10, and can be disposed at any position on the housing assembly 10, depending on the design requirements.

[0082] like Figure 5 As shown, in one embodiment, the main unit 100 of the ventilation device further includes an air inlet guide 108, which, together with the back plate 11, forms an air intake cavity that communicates with the air inlet 15 and has an open top. In one embodiment, the air inlet guide 108 includes a baffle 1081 and three side plates 1082 surrounding the three edges of the baffle 1081. The baffle 1081 is opposite to the air inlet 15, and the three side plates 1082 are respectively located on the left, right and bottom sides of the air inlet 15 and are sealed to the back plate 11. The air inlet guide 108 and the back plate 11 form an air intake cavity that communicates with the air inlet 15 and has an open top. In this embodiment, when the fan assembly 107 is running, gas enters the intake chamber through the air inlet 15 and, guided by the air inlet guide 108, is blown towards the upper region A1 where the control board 80 is located. After hitting the control board 80, the gas folds downwards, passes through the gas output assembly 20, the oxygen control assembly 40, and the pressure monitoring assembly 30, then flows to the display screen 102 and, after passing through the turbine assembly 104, flows to the outlet 16 and diffuses out. In this embodiment, the airflow sequentially passes through the heat-sensitive components of the control board 80, the display screen 102, and the turbine assembly 104, achieving effective heat dissipation.

[0083] It should also be noted that the three side plates 1082 of the air inlet guide 108 are located on the left, right and bottom sides of the air inlet 15 and are sealed to the back plate. In this embodiment, the air inlet guide 108 can also play a waterproof role. When liquid enters the housing assembly 10 from the air inlet 15, the liquid will remain in the air inlet cavity for a moment and then be discharged from the air inlet 15 due to the obstruction of the air inlet guide 108. This can effectively prevent liquid from directly entering the housing assembly 10, thereby achieving a better waterproof effect.

[0084] like Figure 4 As shown, in one embodiment, the second side plate 13 is recessed inward to form an assembly cavity 131, which communicates with the air inlet 15 of the turbine assembly 104. The ventilation equipment main unit 100 also includes a filter assembly G, which is detachably housed within the assembly cavity 131.

[0085] In one embodiment, the ventilation equipment main unit 100 further includes an oxygen interface assembly 105, which, along with the filter assembly G, is located in the first region B1 and below the fan assembly 107. This implementation makes efficient use of the space below the fan assembly 107, facilitating miniaturization of the ventilation equipment main unit 100.

[0086] like Figure 1 and Figure 3As shown, in one embodiment, the housing assembly 10 includes a rear housing assembly, which may include a back panel 11, a first side panel 12, a second side panel 13, and a bottom panel 17. In another embodiment, as... Figure 1 As shown, the rear housing assembly includes a back panel 11, a first side panel 12, a second side panel 13, a bottom panel 17, and a top connecting plate 18 that connects along the length YY direction of the housing assembly 10 between a portion of the top of the first side panel 12 and the second side panel 13. The housing assembly 10 also includes a handle 19. The handle 19 can be attached to the top connecting plate 18, and the surface of the handle 19 on one side of the panel 14 is higher than the panel 14. In this embodiment, if the ventilation device main unit 100 is accidentally dropped, the handle 19 will contact the contact surface first, thereby protecting the panel 14 and reducing the possibility of damage to the display screen 102.

[0087] The gas output assembly 20, oxygen control assembly 40, and pressure monitoring assembly 30 are mounted on the rear housing assembly, which may include portions made of metal. In this embodiment, the metal rear housing assembly has high strength and provides good protection for the gas output assembly 20, oxygen control assembly 40, and pressure monitoring assembly 30. If the ventilation equipment main unit 100 is accidentally dropped, the metal rear housing assembly can provide good protection for the internal gas output assembly 20, oxygen control assembly 40, and pressure monitoring assembly 30, reducing the possibility of damage to these components. The metal rear housing assembly may be, but is not limited to, made of magnesium alloy, aluminum alloy, or magnesium-aluminum alloy.

[0088] In one embodiment, the ventilation device main unit 100 further includes a flexible element R that at least covers a portion of the surface of the housing assembly 10. In one embodiment, the flexible element R at least covers a portion of the surface of the rear housing assembly.

[0089] Preferably, the flexible element R covers the joints of multiple surfaces of the housing assembly 10, and the outer surface of the flexible element R is higher than the corresponding surfaces of the housing assembly 10. In the illustrated embodiment, the flexible element R covers the perimeter of the base plate 17, the joint between the first side plate 12 and the front panel 14, the joint between the second side plate 13 and the front panel 14, the joint between the back plate 11 and the top connecting plate 18, and at least part of the handle 19. The invention is not limited thereto; the coverage area of ​​the flexible element R may be more or less than the areas listed above, and the flexible element R may be continuous or discontinuous.

[0090] In this embodiment, the flexible element R acts as a buffer. Since the flexible element R covers the joints of multiple surfaces of the housing assembly 10, and the outer surface of the flexible element R is higher than the corresponding surfaces, when the ventilation equipment main unit 100 is accidentally dropped, the flexible element contacts the ground first, effectively buffering the impact and further providing better protection for the gas output assembly 20, oxygen control assembly 40, and pressure monitoring assembly 30. The flexible element can be, but is not limited to, a silicone component.

[0091] An embodiment of the present invention also proposes a ventilation device, which includes an intake branch and the aforementioned ventilation device main unit 100, wherein the intake branch is connected to the gas output component 20.

[0092] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
