[0067] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0068] Please also refer to Figures 1-14 This utility model provides some preferred embodiments of a ventilator. The ventilator can be a medical ventilator or a home ventilator. A home ventilator can be a sleep apnea machine.

[0069] like Figure 1 As shown, the ventilator of this application includes a noise-reducing fan structure 20. The noise-reducing fan structure 20 is configured to inhale oxygen and / or ambient air, increasing gas flow rate and pressure, and reducing noise during gas flow. The noise-reducing fan structure 20 includes a noise-reducing chamber 21. The noise-reducing chamber 21 can reduce noise during gas flow. The noise-reducing fan structure 20 also includes a fan 22. The fan 22 can increase gas flow rate and create a low pressure on the inlet side, causing gas to be drawn into the noise-reducing chamber 21. After the inhaled gas enters the noise-reducing chamber 21, the flow velocity is increased by the fan 22, and although the gas flow rate increases throughout the flow process, the noise remains at a low level. The noise-reducing fan structure 20 also includes a flow sensor 23. The flow sensor 23 can detect the gas flow rate on the outlet side of the fan 22. The noise-reducing fan structure 20 also includes a pressure sensor 24. The pressure sensor 24 can detect the gas pressure on the outlet side of the fan 22.

[0070] like Figure 1As shown, the ventilator of this application includes a heated humidification structure 40. The heated humidification structure 40 is configured to heat water to form water vapor and mix it with gas to obtain gas with suitable temperature and humidity. The heated humidification structure 40 includes a water reservoir 41. The water reservoir 41 can store water. The heated humidification structure 40 also includes a heater 42. The heater 42 can heat and evaporate the water in the water reservoir 41. The heated humidification structure 40 also includes a temperature sensor 43. The temperature sensor 43 can detect the temperature of the water in the water reservoir 41 or detect the temperature of the gas in the water reservoir 41.

[0071] like Figure 1 As shown, the ventilator of this application includes a controller 30. The controller 30 is configured to activate and deactivate the noise-reducing fan structure 20, and to activate and deactivate the heating and humidification structure 40. The ventilator of this application also includes a display screen 50. The display screen 50 can display images and can also serve as a human-machine interface.

[0072] Figure 1 The hollow arrow indicates the direction of gas flow. After the gas enters the noise reduction chamber 21, the flow rate is increased by the fan 22 and it is transported to the water storage tank 41. The gas mixes with the evaporated water vapor to form a gas with a certain temperature and humidity, which is output at a certain flow rate.

[0073] Figure 1 The solid arrow indicates the signal output direction. Controller 30 is electrically connected to fan 22, and can start, stop, and adjust the fan speed. Controller 30 is electrically connected to flow sensor 23, and can acquire the flow rate value collected by flow sensor 23. Controller 30 is electrically connected to pressure sensor 24, and can acquire the pressure value collected by pressure sensor 24. Controller 30 is electrically connected to heater 42, and can start, stop, and adjust the power of heater 42. Controller 30 is electrically connected to temperature sensor 43, and can acquire the temperature value collected by temperature sensor 43. Controller 30 is electrically connected to display screen 50. Controller 30 can drive display screen 50 to display images.

[0074] like Figure 2 As shown, the ventilator of this application includes a housing 10. The housing 10 is generally cubic in shape and is a semi-enclosed structure, with a portion of the heating and humidification structure 40 exposed outside the housing 10 (see [link]). Figure 3 The noise-reducing fan structure 20 and the controller 30 are enclosed within the housing 10 (see [reference]). Figure 6The housing 10 is equipped with a filter 60 and a second connecting pipe 72. The filter 60 filters the gas and then delivers it to the noise-reducing fan structure 20. The second connecting pipe 72 can be connected to a breathing mask, breathing face mask, breathing nasal mask, or breathing nasal plug. The second connecting pipe 72 outputs gas with a certain temperature and humidity at a certain flow rate to the breathing mask, breathing face mask, breathing nasal mask, or breathing nasal plug.

[0075] like Figure 3 As shown, the housing 10 is also equipped with a display screen 50 and buttons 51. The display screen 50 can display temperature, humidity, flow rate, pressure, etc. The buttons 51 include at least one of adjustment buttons or switch buttons. The adjustment buttons adjust the temperature, flow rate, pressure, etc., for example, adjusting the speed of the fan 22 or adjusting the power of the heater 42; the switch buttons turn the noise-reducing fan structure 20 or the heating and humidification structure 40 on or off, for example, turning the fan 22 on and off or the heater 42 on and off. In other embodiments, the display screen 50 includes a touch screen. Human-computer interaction is performed through the touch screen to realize the functions of the adjustment buttons and the switch buttons.

[0076] like Figure 4 As shown, the housing 10 has a first side surface 11, on which an air inlet 15 is formed, and a filter 60 is installed in the air inlet 15 (see...). Figure 2 A vent 16 is formed on the first side 11, and a second connecting pipe 72 is installed at the vent 16 (see...). Figure 2 The air inlet 15 is positioned lower than the air outlet 16. The air inlet 15 is located at the lower end of the first side 11, and the air outlet 16 is located at the upper end of the first side 11. The air inlet 15 is located at the end of the first side 11 furthest from the heating and humidifying structure 40, and is closer to the noise reduction fan structure 20. The air outlet 16 is located in the middle of the first side 11. The fact that both the air inlet 15 and the air outlet 16 are located on the first side 11 facilitates the connection of the second connecting tube 72 to a breathing mask, breathing face mask, breathing nasal mask, or breathing nasal plug, and also facilitates observation of whether the air inlet 15 is blocked. The housing 10 has a fourth side 14, on which an opening 17 is formed. The heating and humidifying structure 40 is located within the opening 17 (see...). Figure 2 The fourth side 14 and the first side 11 are two adjacent sides. The housing 10 also has a top surface and a bottom surface. In other embodiments, the first side 11 may also form a power socket for connecting a power source.

[0077] like Figure 5 As shown, the housing 10 has a second side surface 12, which is closed. The housing 10 also has a third side surface 13, on which a first mounting hole 18 is formed for mounting the display screen 50. A second mounting hole may also be formed on the top surface for mounting a button 51 (see [reference]). Figure 3The third side 13 and the second side 12 are two adjacent sides. The first side 11, the second side 12, the third side 13, and the fourth side 14 are connected in sequence, so the first side 11 and the third side 13 are in opposite positions, and the second side 12 and the fourth side 14 are in opposite positions. The first mounting hole 18 is located on the third side 13, and the air outlet 16 is located on the first side 11. Thus, the display screen 50 and the second connecting tube 72 are located on two opposite sides, which facilitates the user to connect the breathing mask, breathing face mask, breathing nasal mask, or breathing nasal plug to the second connecting tube 72, and also facilitates the nursing staff to observe the display screen 50.

[0078] like Figure 6 As shown, the noise-reducing fan structure 20 and the heating and humidifying structure 40 are arranged side by side and close to each other, located on both sides of the second connecting pipe 72. The noise-reducing fan structure 20 is closer to the second side 12 (see...). Figure 2 The heated humidification structure 40 is closer to the fourth side 14 (see...). Figure 4 With the controller 30 and the second connecting pipe 72 located on opposite sides of the noise-reducing fan structure 20, the controller 30 is closer to the third side 13 (see...). Figure 3 It facilitates the connection of the display screen 50 and the button 51.

[0079] like Figure 7 As shown, the noise-reducing fan structure 20 forms an integral modular structure, the heating and humidification structure 40 forms an integral modular structure, and the controller 30 forms an integral modular structure, facilitating installation, disassembly, and replacement. The noise-reducing fan structure 20 and the heating and humidification structure 40 are connected by a first connecting pipe 71. A second connecting pipe 72 is connected to the heating and humidification structure 40.

[0080] like Figure 8 As shown, the heating and humidifying structure 40 has a first inlet 401 and a first outlet 402. The first inlet 401 is connected to a first connecting pipe 71, and the first outlet 402 is connected to a second connecting pipe 72. The gas output from the noise-reducing fan structure 20 enters the first inlet 401 of the heating and humidifying structure 40 through the first connecting pipe 71 and flows out from the first outlet 402 of the heating and humidifying structure 40. It is then delivered to a breathing mask, breathing face mask, breathing nasal mask, or breathing nasal plug through the second connecting pipe 72.

[0081] like Figure 9 As shown, the noise-reducing fan structure 20 has a second inlet 201, which is connected to the air intake 15 (see...). Figure 4 Gas enters the second inlet 201 through the air inlet 15.

[0082] like Figure 10 As shown, the noise-reducing fan structure 20 has a second outlet 202, which is connected to the first connecting pipe 71 (see...). Figure 8 Fan 22 is located inside noise reduction chamber 21. Gas enters noise reduction chamber 21 through second inlet 201, and the gas flow rate is increased by fan 22. Then it flows out from second outlet 202, and enters heating and humidification structure 40 through first connecting pipe 71 (see...). Figure 8 In other embodiments, fan 22 is a turbofan 22, which can increase the gas flow rate to a higher level. Flow sensor 23 and pressure sensor 24 can be installed near the second outlet 202.

[0083] like Figure 11 As shown, the heating and humidification structure 40 forms an integral modular structure.

[0084] like Figure 12 As shown, the heating and humidification structure 40 includes a mounting base 413, which can mount a water storage tank 41 and a heater 42. The mounting base 413 can be fixed to the housing 10, and the water storage tank 41 can be pulled out from the mounting base 413 and pass through the opening 17 (see...). Figure 4 The water storage tank 41 can be removed by placing it on the tank body 411 and removing it from the tank body 412. The tank body 412 can be detached from the tank body 411 or rotated relative to the tank body 411 to facilitate adding water to the tank body 411, emptying water from the tank body 411, and cleaning the tank body 411. In other embodiments, the temperature sensor 43 can be installed in the water storage tank 41 or on the mounting base 413. The first inlet 401 and the first outlet 402 of the heating and humidification structure 40 are formed on the mounting base 413. The water storage tank 41 can be made of a transparent material to allow observation of the water level inside the water storage tank 41.

[0085] like Figure 13 As shown, a first tube 4121 and a second tube 4122 are provided inside the cover 412. The first end of the first tube 4121 faces the first inlet 401 of the heating and humidification structure 40 and is connected to the noise reduction fan structure 20 (see...) via the first connecting pipe 71. Figure 8 The second end of the first tube 4121 is bent toward the heater 42 at the bottom of the water storage tank 41. The first end of the second tube 4122 faces the first outlet 402 and is connected to the vent 16 (see) via the second connecting pipe 72.
