Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a ventilation device host and a ventilation device. Background Art

[0002] In order to facilitate the assembly and testing of core components, the ventilation device host of the existing ventilation device integrates the core components into the core bracket and combines with the core bracket to form a core module, and then installs the core module into the shell. Although this design method is convenient for the assembly and testing of core components, the use of the core bracket causes the overall weight of the ventilation device host of the ventilation device to be relatively large, and the internal space of the ventilation device cannot be reasonably utilized, resulting in a large volume of the ventilation device host of the ventilation device, which cannot meet the requirements for lightweight and miniaturized ventilation devices in emergency and transportation occasions. Summary of the invention

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

[0004] The ventilation device host provided in the first aspect of the present invention comprises:

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

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

[0007] a turbine assembly, disposed inside the housing assembly to receive the oxygen output by the oxygen control assembly;

[0008] a gas output assembly, disposed on the housing assembly, the gas output assembly being used to receive the gas output by the turbine assembly and to connect to an inhalation branch for delivering gas to a patient; and

[0009] A pressure monitoring component, disposed inside the housing component, the pressure monitoring component being 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 comprises a first support member, wherein the first support member divides the interior space of the housing assembly into an upper area and a bottom area;

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

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

[0013] The ventilation device provided in the second aspect of the present invention comprises an air inhalation branch and the above-mentioned ventilation device host, wherein the air inhalation branch is connected to the gas output component.

[0014] From the above technical scheme, it can be seen that the ventilation device host proposed in the first aspect of the present invention, by setting the first supporting component, the internal space of the shell assembly is divided into an upper area and a bottom area, the gas output assembly, the oxygen control assembly, the pressure monitoring assembly, and the turbine assembly are arranged in the upper area, and the bottom area is used to accommodate the battery assembly. In this way, the first supporting component separates the chamber where the gas output assembly, the oxygen control assembly and the pressure monitoring assembly are installed from the chamber where the battery assembly is installed, which is beneficial to 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 area to accommodate the battery assembly, when the bottom area accommodates the battery assembly, the center of gravity of the ventilation device host as a whole can be lowered, so that the ventilation device host can be stably placed on the bearing surface. In addition, by setting at least one of the gas output assembly, the oxygen control assembly, the pressure monitoring assembly and the turbine assembly to be fixed on the shell assembly, there is no need to fix the four to the same bracket and then assemble them to the shell assembly, eliminating the large volume and heavy weight of the bracket, which can effectively reduce the overall weight of the ventilation device host, so that the ventilation device host is lightweight and the volume of the ventilation device host is reduced.

[0027] 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.

[0028] like Figures 1 to 6 As shown, an embodiment of the present invention proposes a ventilation device host 100, and the proposed ventilation device host 100 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. The first side plate 12 and the second side plate 13 are respectively arranged on opposite sides of the back plate 11, and the panel 14 is arranged opposite to the back plate 11. The oxygen control assembly 40 is arranged inside the housing assembly 10, and the oxygen control assembly 40 is used to connect the oxygen supply device. The turbine assembly 104 is arranged inside the housing assembly 10 to receive the oxygen output by the oxygen control assembly 40. The gas output assembly 20 is arranged in the housing assembly 10, and the gas output assembly 20 is used to receive the gas output by the turbine assembly 104, and is used to connect the inhalation branch for delivering gas to the patient. The pressure monitoring component 30 is disposed inside the shell component 10. The pressure monitoring component 30 is used to communicate with the gas output component 20 to monitor the 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 further includes a first support member 60, which divides the internal space of the housing assembly 10 into an upper area A1 and a bottom area A2. The gas output assembly 20, the oxygen control assembly 40, the pressure monitoring assembly 30, and the turbine assembly 104 are arranged in the upper area A1, and at least one of them is fixed to the housing assembly 10, and the bottom area A2 is used to accommodate the battery assembly.

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

[0031] At least one of them being fixed on the housing assembly 10 may be: one of them being fixed on the housing assembly 10, and the other two of them being fixed on the housing assembly 10 through the same bracket, or the other three of them being fixed on the housing assembly 10 through the same bracket. At least one of them being fixed on the housing assembly 10 may also be: two of them being fixed on the housing assembly 10 respectively, and the other two of them being fixed on the housing assembly 10 through, for example, the same bracket. At least one of them being fixed on the housing assembly 10 may also be: all four of them being fixed on the housing assembly 10.

[0032] Throughout the present application, "one of them", "two of them", or "four of them" of the gas output assembly 20, the oxygen control assembly 40, the pressure monitoring assembly 30, and the turbine assembly 104 are fixed on the shell assembly 10, and the "fixed" emphasizes that they are connected to the shell assembly separately, that is, they are not connected to the shell assembly 10 with any other of the four through a common large-volume bracket. The "separate connection" here can be directly fastened to the shell assembly 10 by fasteners alone. Of course, it can also be dispersedly fixed to the shell assembly 10 through small-volume partitions, sheet metal parts, connecting columns, brackets and other supporting parts. The specific details can be determined according to actual design needs. Since there is no need to fix these four to the same bracket and then assemble them to the shell assembly 10, the large and heavy bracket is omitted, which can make the ventilation device host 100 smaller in size and lighter in weight.

[0033] The ventilation device host 100 proposed in the embodiment of the present invention divides the internal space of the shell component 10 into an upper area A1 and a bottom area A2 by setting a first support component 60. The gas output component 20, the oxygen control component 40, the pressure monitoring component 30, and the turbine component 104 are set in the upper area A1, and the bottom area A2 is used to accommodate the battery component. In this way, the first support component 60 separates 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 battery component 50 is installed, which is beneficial to the protection between the two components, reduces the mutual influence between the two components, and improves the safety performance. Secondly, by setting the bottom area A2 to accommodate the battery component, when the bottom area A2 accommodates the battery component, the center of gravity of the ventilation device host 100 as a whole can be lowered, so that the ventilation device host 100 can be stably placed on the bearing surface. In addition, by fixing at least one of the gas output assembly 20, the oxygen control assembly 40, the pressure monitoring assembly 30 and the turbine assembly 104 on the shell assembly 10, there is no need to fix the four on the same bracket and then assemble them on the shell assembly 10, thereby eliminating the need for a large and heavy bracket, and effectively reducing the overall weight of the ventilation device host 100, thereby achieving lightweight of the ventilation device host 100 and reducing the volume of the ventilation device host 100.

[0034] In one embodiment, the first support member 60 is fixedly 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 component 60 is provided with a hollow structure. With this embodiment, the weight of the first support component 60 can be reduced, thereby reducing the weight of the ventilation device host 100, which is conducive to achieving lightweight ventilation device host 100. It should be noted that the above-mentioned setting is not limited to the above-mentioned setting method. For example, in another embodiment, the first support component 60 can be set to a ring shape. With this embodiment, the weight of the first support component 60 can be greatly reduced. Of course, it is also possible to set the first support component 60 as a complete component, which can be determined according to actual design needs.

[0036] In one embodiment, the first support component 60 is connected to the first side plate 12, the second side plate 13, and the back plate 11. That is, the first support component 60 is separately provided relative to the first side plate 12, the second side plate 13, and the back plate 11, and the first support component 60 is connected to the first side plate 12, the second side plate 13, and the back plate 11 through a mechanical structure. Of course, it is also possible that the first support component 60, the first side plate 12, the second side plate 13, and the back plate 11 are provided as an integral molding.

That is, the first support component 60 is separately provided relative to the second side plate 13 and the back plate 11, and the first support component 60 is connected to the second side plate 13 and the back plate 11 through a mechanical structure. Of course, it is also possible that the first support component 60, the second side plate 13, and the back plate 11 are provided as an integral molding.

[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 adjust the oxygen flow rate, and the first flow sensor is used to monitor the oxygen flow rate.

[0040] In one embodiment, the gas output assembly 20 includes a release valve and a second flow sensor, wherein 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, and the second flow sensor is used to monitor the flow of the output gas.

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

[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 independently arranged. The gas output assembly 20 is installed on the back plate 11 or the first side plate 12, and extends from the first side plate 12 to the outside of the shell assembly 10.

[0043] like Figure 4 and Figure 5 As shown, in one embodiment, the pressure monitoring assembly 30 is installed on the first supporting member 60. It should be noted that the pressure monitoring assembly 30 is not limited to being installed on the first supporting member 60. For example, in some other embodiments, the pressure monitoring assembly 30 can be installed 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 host 100 also includes an interface component F for connecting the inhalation branch and the pressure monitoring component 30, the pressure monitoring component 30 is installed on the back plate 11, and the interface component F is connected to the first side plate 12. In this embodiment, by separately arranging 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, so that the internal space of the shell component 10 can be reasonably utilized to reduce the size of the ventilation device host 100. Not limited to the above-mentioned embodiment, for example, in another embodiment, the pressure monitoring component 30 is installed on the first side plate 12, and the interface component F is connected to the panel 14.

[0045] In one embodiment, the pressure monitoring assembly 30 is in communication with the turbine assembly 104 to monitor parameters associated with the gas output by the turbine assembly 104 .

[0046] In another embodiment, the pressure monitoring component 30 is in communication with the interface component F to monitor relevant parameters of the gas input into 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 can be mounted on the back plate 11 or the first side plate 12.

[0048] like Figure 3 and Figure 5 As shown, in one embodiment, the ventilation device host 100 further includes a second support member 70, which is horizontally arranged between the first side plate 12 and the second side plate 13 to separate the upper area A1 into a top area A11 and a middle area A12, and the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30 are located in the middle area A12. The ventilation device host 100 further includes a control panel 80, which is located in the top area A11. In this embodiment, by arranging the control panel 80 in the top area A11, the control panel 80 generates more heat when working, which will heat the surrounding air, and the hot air will stay in the top area A11, thereby reducing the influence of the hot air on the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30. In addition, by arranging the second support member 70, the chamber where the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30 are installed is separated from the chamber where the control panel 80 is installed, which is beneficial to the protection between the two parts of the components, reduces the mutual influence between the two parts of the components, and improves the safety performance.

[0049] In one embodiment, the control panel 80 is laid flat on the upper area A1. This embodiment reduces the space occupied by the control panel 80, so that the overall height of the ventilation device host 100 is lower.

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

[0051] like Figure 3 and Figure 5 As shown, in one embodiment, the ventilation device host 100 further includes a support assembly 90 for supporting the second support component 70, and the support assembly 90 is installed between the first support component 60 and the second support component 70. In this embodiment, by providing the support assembly 90 between the first support component 60 and the second support component 70 to form a support, the support strength of the control panel 80 can be improved. The support assembly 90 can be, but is not limited to, a support assembly 90 made of a metal material. It can be understood that the support assembly 90 can also increase the strength of the entire housing assembly 10 and improve the impact resistance of the housing assembly 10. When the ventilation device host 100 accidentally falls, the deformation of the housing assembly 10 under the action of the impact force can be reduced, thereby providing a better protection effect 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, and the crossbeam 91 and the support rod 92 may both be in an elongated shape. The crossbeam 91 is connected to the back plate 11. The support rod 92 is connected between the crossbeam 91 and the first support component 60. The second support component 70 is connected to the crossbeam 91 and supported by the crossbeam 91, and the control board 80 is mounted on the second support component 70.

In this embodiment, the control board 80 is fixed by clamping the reinforcement plate 1012 and the second support member 70. Compared with the existing control board 80 fastened by screws, the fixing method of the control board 80 proposed in this embodiment does not affect the stress of the screw connection, which can reduce the situation that the control board 80 is deformed by stress during assembly, resulting in circuit disconnection and damage, thereby improving the yield rate of the device.

[0054] In addition, in this embodiment, when the ventilation device main unit 100 accidentally falls on its top, the reinforcement 101 can protect the control panel 80 and prevent the control panel 80 from being damaged. The reinforcement 101 can be, but is not limited to, a reinforcement 101 made of metal material.

[0055] like Figure 5 As shown, in one embodiment, the ventilation device host 100 further includes a physiological parameter acquisition component, which is used to connect to the physiological parameter sensor and collect 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 panel 12 or the panel 14.

[0057] In one embodiment, the oxygen control component 40 and the pressure monitoring component 30 are arranged sequentially in the direction from the back plate 11 to the panel 14. In some embodiments, in order to facilitate the viewing of the display screen 102, the panel 14 is tilted so that the ventilation device host 100 is narrow at the top and wide at the bottom. In this embodiment, the oxygen control component 40 and the pressure monitoring component 30 are arranged below the gas output component 20, and the oxygen control component 40 and the pressure monitoring component 30 are arranged sequentially in the direction from the back plate 11 to the panel 14. In this way, the pressure monitoring component 30, the oxygen control component 40 and the gas output component 20 are also arranged in a narrow at the top and wide at the bottom, so that the internal space of the shell component 10 can be reasonably utilized, so that the ventilation device host 100 can be miniaturized.

[0058] like Figures 2 to 4 As shown, in one embodiment, the housing assembly 10 includes a first area B1, a second area B2 and a third area B3 arranged in sequence along the length direction YY from the second side plate 13 to the first side plate 12.

In this embodiment, by separately arranging 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, so that the internal space of the housing assembly 10 can be reasonably utilized to reduce the size of the ventilation device host 100.

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

[0063] In one embodiment, the ventilation device host 100 further includes a battery assembly 50, and the battery assembly 50 is located in the bottom area A2.

[0064] In one embodiment, the bottom area A2 and the battery assembly 50 are both flat, and the battery assembly 50 is laid flat on the bottom area A2. This embodiment is conducive to lowering the center of gravity of the ventilation device host 100, making the ventilation device host 100 more stable, and can reduce the height of the entire ventilation device host 100 to meet the miniaturization requirements.

[0065] like Figure 6 As shown, in one embodiment, the back plate 11 is provided with an assembly port 111, the assembly port 111 is communicated with the bottom area A2, and the battery assembly 50 is loaded into the bottom area A2 through the assembly port 111. The ventilation device host 100 also includes a clamping assembly 106, which can be movably mounted on the back plate 11, and the clamping assembly 106 is used to clamp the battery assembly 50 in the bottom area A2. In this embodiment, by providing the clamping assembly 106 to clamp the battery assembly 50 in the bottom area A2, it is possible to avoid the ventilation device host 100 being subjected to vibration and impact in a harsh transportation environment, resulting in damage to the battery and / or falling out of the ventilation device host 100.

[0066] like Figures 6 to 9 As shown, in one embodiment, the assembly opening 111 includes a first side arranged along the up-down direction shown in the figure and a second side opposite to the first side, the first side of the assembly opening 111 is provided with a first assembly portion C1, and the second side of the assembly opening 111 is provided with a protrusion C2. The clamping assembly 106 includes a cover assembly 1061, a locking tongue 1062 and an elastic member 1063, the cover assembly 1061 is provided with a second assembly portion C3, and the second assembly portion C3 is used to connect with the first assembly portion C1.

In this embodiment, when the operator presses the second side of the cover assembly 1061, the protrusion C2 abuts against the first inclined surface 1064, and the force of the protrusion C2 acting on the first inclined surface 1064 pushes the lock tongue 1062 downward until the protrusion C2 passes over the lock tongue 1062 and is clamped to the second side of the lock tongue 1062, that is, the installation of the second side of the cover assembly 1061 is completed, and this embodiment makes the cover assembly 1061 easy to install.

As mentioned above, a latch position D is provided on the cover assembly 1061. When installing the cover assembly 1061, the operator may also press the lock tongue 1062 downward through the latch position D to move the cover assembly 1061 into place, and then release the lock tongue 1062. The lock tongue 1062 may move upward under the action of the elastic member 1063 until the protrusion C2 is locked on the second side of the lock tongue 1062.

[0069] In one embodiment, a second inclined surface 1065 is provided on the second side of the first end of the locking tongue 1062, and the second inclined surface 1065 extends obliquely from the end of the first end of the locking tongue 1062 toward the second side of the locking tongue 1062. In this embodiment, by providing the second inclined surface 1065, the protrusion C2 acts on the second inclined surface 1065, and a component force that presses the cover plate assembly 1061 toward the battery assembly 50 is always maintained, so that the cover plate assembly 1061 can remain stable and will not shake. Of course, it is also possible that the second side of the locking tongue 1062 is not provided with the second inclined surface 1065, which can be determined according to 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 is a protrusion and the second assembly part C3 is a groove, which can be determined according to actual design needs.

[0071] The installation and removal 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 assembly 1061, so that the first inclined surface 1064 of the first end of the lock tongue 1062 abuts against the protrusion C2, and the force of the protrusion C2 acting on the first inclined surface 1064 pushes the lock tongue 1062 to move downward until the protrusion C2 passes over the first end of the lock tongue 1062 and is clamped on the second side of the lock tongue 1062, and the installation of the clamping assembly 106 is completed. Of course, the operator can also press the lock tongue 1062 to make the lock tongue 1062 move downward, and then press the second side of the cover assembly 1061 into place so that the protrusion C2 is located on the second side of the lock tongue 1062, and then release the lock tongue 1062, and the lock tongue 1062 moves upward under the push of the elastic member 1063 until the protrusion C2 is clamped on the second side of the lock tongue 1062. When the clamping assembly 106 needs to be removed, the operator inserts his finger into the buckle position D to press the locking tongue 1062, so that the locking tongue 1062 is disengaged from the protrusion C2, and the clamping assembly 106 can be taken out.

[0072] It should be noted that the pressing assembly 106 is not limited to the above-mentioned configuration. For example, in another embodiment, Fig.10 and Fig.11 As shown, the clamping assembly 106 includes a clamping member 1066, and the clamping member 1066 includes a first end and a second end opposite to the first end, and the first end of the clamping member 1066 is provided with a second assembly portion C3, and the second end of the clamping member 1066 is provided with a snap portion C4, wherein the second assembly portion C3 is rotatably connected to the first assembly portion C1, and the snap portion C4 is snapped with the protrusion C2.

[0073] In one embodiment, the second end of the pressing member 1066 includes an elastic arm 1067, and the elastic arm 1067 may include a bent portion, and the bent portion is connected to the main body of the pressing member 1066. When the elastic arm 1067 is subjected to a squeezing force, it will deform toward the first end of the pressing member 1066, and after the squeezing force is removed, the elastic arm 1067 will return to its original position. The buckle portion C4 includes a first protruding portion C41 and a second protruding portion C42 spaced from the first protruding portion C41, and the protrusion C2 is clamped between the first protruding portion C41 and the second protruding portion C42.

[0074] like Fig.11As shown, in one embodiment, the pressing member 1066 includes a first side and a second side opposite to the first side, and the first side of the pressing member 1066 faces the battery assembly 50. The pressing assembly 106 also includes a shock absorbing member 1068, which is disposed on the first side of the pressing member 1066 and abuts against the battery assembly 50. In this embodiment, the shock absorbing member 1068 can press the battery assembly 50 and play a role in shock absorption and buffering the battery assembly 50. The shock absorbing member 1068 can be, but is not limited to, a sponge or PE (polyethylene) foam.

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

[0076] The installation and removal 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 clamped between the first protrusion C41 and the second protrusion C42, and then seals the cover assembly 1061 on the assembly opening 111. When the clamping assembly 106 needs to be disassembled, the operator removes the cover assembly 1061, presses the elastic arm 1067 to separate the first protrusion C41 and the second protrusion C42 from the protrusion C2, and then turns the clamping member 1066 away.

[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, and the ventilation device host 100 further includes a fan assembly 107, which is located inside the housing assembly 10, and is used to drive the gas to enter the housing assembly 10 from the first vent 15 and then be discharged from the second vent 16. The fan assembly 107 is installed on the housing assembly 10 and is opposite to 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 influence of the temperature generated by the heat-generating components when they are working on the 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 area B1, and the first vent 15 is located in the third area B3. With this embodiment, the flow path of the airflow after entering the shell assembly 10 can be extended, so that more heat inside the shell assembly 10 can be carried away, and a better heat dissipation effect can be achieved. In addition, with this embodiment, the assembly layout is reasonable, the gas output assembly 20 and the pressure monitoring assembly 30 are located on the same side of the shell assembly 10, and the interface can be set on the same side panel to facilitate subsequent pipeline connection. Moreover, the turbine assembly 104 is located between the air inlet 15 and the air outlet 16. The airflow entering the shell assembly 10 from the air inlet 15 will pass through the turbine assembly 104 and then be discharged from the air outlet 16, which can achieve a better heat dissipation effect on 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, which is arranged near the bottom of the housing assembly 10, and the second vent 16 is an air outlet 16, which is arranged near the top of the housing assembly 10. When the fan assembly 107 is running, the airflow enters the interior of the housing assembly 10 from the air inlet 15, flows through the pressure monitoring assembly 30 and the turbine assembly 104, and then is discharged from the air outlet 16. According to physical principles, hot air has a small density and will automatically flow upward. In this embodiment, by arranging the air outlet 16 near the top of the housing assembly 10, the hot air flow can be directly discharged from the air outlet 16 when it automatically flows to the top of the housing assembly 10, avoiding the hot air flow from flowing inside the housing assembly 10, and achieving a better heat dissipation effect.

[0080] In addition, it should be noted that, as can be seen from the above, the control panel 80 of the ventilation device host 100 is arranged in the top area A11 of the shell assembly 10. In this way, the heat generated by the control panel 80 during operation can be directly discharged from the air outlet 16, thereby avoiding the heat generated by the control panel 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 arranged on the back plate 11, and the air outlet 16 can also be arranged on the back plate 11 and is arranged diagonally with the air inlet 15. In another embodiment, the air inlet 15 is arranged on the back plate 11, and the air outlet 16 is arranged on the second side plate 13 or is located on the same side as the second side plate 13, and the air outlet 16 is arranged diagonally with the air inlet 15. With this embodiment, the flow path of the airflow after entering the interior of the shell assembly 10 can be extended, so that more heat inside the shell assembly 10 can be carried away, 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 arranged on the back plate 11 of the shell assembly 10, and can be arranged at any position of the shell assembly 10, and can be determined according to design requirements.

[0082] like Figure 5 As shown, in one embodiment, the ventilation device host 100 further includes an air inlet guide 108, and the air inlet guide 108 and the back plate 11 are enclosed to form an air inlet cavity that is connected to the air inlet 15 and has an opening at the top. In one embodiment, the air inlet guide 108 includes a baffle 1081 and three side plates 1082 arranged around 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 side, right side and bottom side of the air inlet 15 and are sealed and connected to the back plate 11, and the air inlet guide 108 and the back plate 11 are enclosed to form an air inlet cavity that is connected to the air inlet 15 and has an opening at the top. In this embodiment, when the fan assembly 107 is running, the gas enters the air inlet cavity from the air inlet 15, and is guided by the air inlet guide 108 to blow toward the upper area A1 where the control board 80 is located. After hitting the control board 80, the gas folds downward and passes through the gas output assembly 20, the oxygen control assembly 40, and the pressure monitoring assembly 30, and then flows to the display screen 102 and flows through the turbine assembly 104 to the air outlet 16 and diffuses out. In this embodiment, the airflow passes through the heat-sensitive components of the control board 80, the display screen 102, and the turbine assembly 104 in sequence, and the purpose of effective heat dissipation can be achieved.

[0083] It should also be noted that the three side panels 1082 of the air inlet guide 108 are respectively located on the left side, right side and bottom side of the air inlet 15 and are sealed with the back plate. In this embodiment, the air inlet guide 108 can also play a waterproof role. When liquid enters the shell assembly 10 from the air inlet 15, due to the obstruction of the air inlet guide 108, the liquid will be retained in the air inlet cavity for a while and then discharged from the air inlet 15, which can effectively prevent the liquid from directly entering the shell 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, and the assembly cavity 131 is connected to the air inlet 15 of the turbine assembly 104. The ventilation device host 100 further includes a filter assembly G, which is detachably accommodated in the assembly cavity 131.

[0085] In one embodiment, the ventilation device host 100 further includes an oxygen interface component 105, and the oxygen interface component 105 and the filter component G are located in the first area B1 and below the fan component 107. In this embodiment, the space below the fan component 107 is reasonably utilized, which is conducive to miniaturization of the size of the ventilation device host 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 plate 11, a first side plate 12, a second side plate 13, and a bottom plate 17. In another embodiment, as shown in FIG. Figure 1 As shown, the rear shell assembly includes a back plate 11, a first side plate 12, a second side plate 13, a bottom plate 17, and a top connecting plate 18 connected between a portion of the top of the first side plate 12 and the second side plate 13 along the length direction YY of the shell assembly 10. The shell assembly 10 also includes a handle 19. The handle 19 can be connected to the top connecting plate 18, and the surface of the handle 19 located on one side of the panel 14 is higher than the panel 14. In this embodiment, when the ventilation device host 100 accidentally falls, the handle 19 first contacts the contact surface, thereby protecting the panel 14 and reducing the possibility of damage to the display screen 102.

[0087] The gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30 are installed on the rear shell assembly, and the rear shell assembly may include a portion made of metal. In this embodiment, the metal rear shell assembly has a high strength and can provide a good protective effect for the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30. When the ventilation device host 100 accidentally falls, the metal rear shell assembly can provide a good protection for the internal gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30, and reduce the possibility of damage to the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30. The metal rear shell assembly can be made of, but not limited to, magnesium alloy, aluminum alloy and magnesium-aluminum alloy.

[0088] In one embodiment, the ventilation device host 100 further includes a flexible member R, and the flexible member R covers at least a portion of the surface of the housing component 10. In one embodiment, the flexible member R covers at least a portion of the surface of the rear housing component.

[0089] Preferably, the flexible member R covers the connection of multiple surfaces of the shell assembly 10, and the outer surface of the flexible member R is higher than the corresponding surfaces of the shell assembly 10. In the illustrated embodiment, the flexible member R covers the surrounding of the bottom plate 17, the connection between the first side plate 12 and the panel 14, the connection between the second side plate 13 and the panel 14, the connection between the back plate 11 and the top connecting plate 18, and at least part of the handle 19. The present invention is not limited to this, and the coverage area of ​​the flexible member R can be more or less than the above-listed areas, and the flexible member R can be continuous or discontinuous.

[0090] In this embodiment, the flexible member R can play a buffering role. Since the flexible member R covers the connection between multiple surfaces of the housing assembly 10, and the outer surface of the flexible member R is higher than the corresponding surfaces, when the ventilation device host 100 accidentally falls, the flexible member first contacts the ground, which can effectively buffer the impact and further form a better protective effect for the gas output assembly 20, the oxygen control assembly 40 and the pressure monitoring assembly 30. The flexible member can be, but is not limited to, a silicone member.

[0091] An embodiment of the present invention further provides a ventilation device, which includes an inhalation branch and the above-mentioned ventilation device host 100 , and the inhalation branch is connected to the gas output component 20 .

[0092] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
