Referring to fig. 1 and 2, there is provided a heating atomization oxygen inhalation device capable of adjusting air flow, which comprises an atomization cup 100, and a gas transmission part 110 and a gas inlet part 120 which are arranged in the atomization cup 100, wherein the outer ring of the atomization cup 100 is communicated with a nozzle 101, the gas transmission part 110 comprises a gas transmission pipe 112 for blowing up liquid medicine in the atomization cup 100 through high-pressure gas, the gas inlet part 120 comprises a gas inlet pipe 121 and a baffle 126 which are positioned at the top of the gas transmission part 110, the baffle 126 is used for guiding the flow state of the blown liquid medicine, so that the gas inlet pipe 121 sucks external gas by utilizing the guiding acting force, a throttle valve 130 is arranged in the gas inlet pipe 121, and the throttle valve 130 is used for controlling the on-off in the gas inlet pipe 121 according to the contact state of people with the nozzle 101.

Specifically, as shown in fig. 3, the air delivery portion 110 includes a liquid storage cup 111 and an air delivery pipe 112, the liquid storage cup 111 is fixed on an inner ring of the atomizing cup 100, preferably, a conical structure is adopted, the air delivery pipe 112 longitudinally penetrates through the liquid storage cup 111, and an opening at a top end of the air delivery pipe 112 is smaller than an opening at a bottom end of the air delivery pipe, so that the conical structure is formed. The advantage of this is that the liquid storage cup 111 bears the liquid medicine, and the conical structure can concentrate less liquid medicine on the outer ring of the gas pipe 112, thereby facilitating the attraction of the liquid medicine (which will be described in detail later), and the gas pipe 112 is connected with the oxygen generator through the connecting pipe 113, so that the oxygen-generating gas enters the gas pipe 112, and the conical shape of the gas pipe 112 can reduce the passing rate of the gas flow, so as to achieve the purpose of compressing the gas.

The baffle 126 is matched with the air delivery part 110 to change the liquid medicine into aerosol, as shown in fig. 4, two sides of the baffle 126 are fixedly connected with the connecting arms 123, the bottom ends of the connecting arms 123 are fixedly connected with the casing 124 sleeved on the outer ring of the air delivery pipe 112, the inner wall of the casing 124 is attached to the outer ring of the air delivery pipe 112, the inner wall of the casing 124 is provided with the suction groove 125, and a gap is reserved between the baffle 126 and the top of the casing 124. In use, as shown in fig. 6, after the gas is ejected through the top end of the gas inlet pipe 121, the flow rate of the ejected gas increases due to the compression of the gas by the top end opening of the gas delivery pipe 112, thereby forming a negative pressure region around. In this way, the liquid medicine stored at the top of the liquid storage cup 111 is sucked to the bottom of the baffle plate 126 through the suction groove 125 under the action of the negative pressure, collides with the air inlet 120 to form aerosol, and then the aerosol is ejected through the nozzle 101 to enter the human body.

In this way, after the gas is blown to the bottom of the baffle 126, the gas and the aerosol are guided by the arc shape of the bottom of the baffle 126, so that a negative pressure area is formed between the air inlet 120 and the baffle 126, and at this time, under the action of negative pressure, the external gas is sucked into the atomizing cup 100 through the air inlet 121, so that the air flow rate sprayed by the nozzle 101 is increased, and the aerosol can be rapidly sprayed out through the nozzle 101.

Further, as shown in fig. 4 and 5, the throttle valve 130 is rotatably disposed at an inner ring of the air inlet pipe 121, one side of the throttle valve 130 is fixedly connected with a transmission shaft 131, one end of the transmission shaft 131 penetrates through the air inlet pipe 121 and the atomizing cup 100, the transmission shaft 131 is rotatably connected with the air inlet pipe 121 and the air delivery part 110, and one end of the transmission shaft 131 is provided with a sliding block 132. The sliding block 132 is slidably disposed at the top of the nozzle 101, a spiral guide groove 133 is formed in an inner ring of the sliding block 132, and a bump 134 engaged in the guide groove 133 is fixedly connected to an outer ring of the transmission shaft 131.

An elastic plate 140 is arranged on one side of the top of the nozzle 101, which is positioned on the sliding block 132, and a return spring 135 which elastically connects the sliding block 132 and the nozzle 101 is arranged between one side of the sliding block 101 and the nozzle 101. When the air inlet pipe 121 is opened, the elastic plate 140 is pressed by lips to deform when people contain the end part of the nozzle 101 in the mouth, so that the elastic plate 140 pushes the sliding block 132 to move, the sliding block 132 moves to drive the transmission shaft 131 to rotate through the guide groove 133, and the transmission shaft 131 drives the air throttle 130 to rotate to open the air inlet pipe 121. Conversely, the slider 132 is elastically returned by the return spring 135, so that the throttle valve 130 closes the intake pipe 121.

Therefore, the throttle valve 130 is utilized to sense the contact between the human body and the nozzle 101, so that the air inlet pipe 121 is opened when a person uses the device, the air inlet pipe 121 is matched with the baffle plate 126 to suck external air, the flow rate of aerosol spraying is increased, and the air inlet pipe 121 is closed when the person leaves the device, so that the flow rate of aerosol spraying is reduced, and the loss caused by the fact that the aerosol flows into the external air is reduced when the person breathes the external air.

In this way, part of the gas in the shunt tube 150 can enter the top of the throttle valve 130 through the shunt tube 150 and then be ejected through the filter element 153, so that the back flushing of the filter element 153 is realized. When the throttle valve 130 is opened, negative pressure is generated in the air inlet pipe 121, and the air sprayed out through the shunt pipe 150 enters the atomizing cup 100 through the air inlet pipe 121, so that circulating flow is formed, and the effect of increasing the flow rate of sprayed aerosol is achieved.

That is, the shunt tube 150 connects the air pipe 112 with the air inlet pipe 121, when people leave the nozzle 101, the air in the air pipe 112 can back flush the filter element 153, and when people contact the nozzle 101, the air in the air pipe 112 can be shunted into the atomizing cup 100 through the air inlet pipe 121 to increase the flow velocity of the aerosol in the atomizing cup 100, so as to adjust the aerosol spraying amount and clean the filter element 153.

In addition, the side wall of the throttle valve 130 is provided with a through hole 136, the lower part of the air inlet pipe 121 is provided with an air outlet passage 152, and the air outlet passage 152 is obliquely arranged. Thus, the gas entering the top of the damper door 130 through the shunt 150 can enter the bottom of the damper door 130 through the orifice 136 and then be ejected to the outer periphery of the baffle 126 through the exhaust passage 152, thereby briefly disturbing the flow state of the aerosol and allowing the aerosol to flow downward, so as to further reduce the amount of aerosol discharged when people breathe outside air.

The air inlet pipe 121 is further provided therein with a heater wire 160, the shunt tube 150 is divided into a main tube 154 and an auxiliary tube 155, the main tube 154 is communicated with the air delivery pipe 112, the auxiliary tube 155 is communicated with the air inlet pipe 121, and an expansion port 156 is provided at the bottom of the auxiliary tube 155. In this way, the gas in the gas delivery pipe 112 is ejected through the main pipe 154 and enters the sub-pipe 155, so that part of the gas in the atomizing cup 100 is sucked through the expansion port 156, and the gas can enter the gas inlet pipe 121 to contact the heater wire 160 a plurality of times, thereby improving the heating efficiency of the gas.
