The water inlet valve 204 is fixedly connected to the box body 202. The driving part 205 is arranged in the atomization chamber 2031. The driving part 205 is used to control the opening and closing of the water inlet valve 204. The atomizer 206 is arranged in the atomization chamber 2031. The first liquid level switch 207 is arranged in the atomization chamber 2031. Preferably, both the driving part 205 and the atomizer 206 are fixedly connected to the atomization cover 203. Specifically, both the driving part 205 and the atomizer 206 are fixedly connected to the bottom of the atomization cover 203. The driving part 205 can be a stepping motor or a servo motor, etc. Preferably, the driving part 205 is a stepping motor.

[0029] The box body 202 is provided with a water storage chamber 2021, a fog inlet end 2022 and a fog outlet end 2023. The water storage chamber 2021 is provided with a water inlet hole 20211. The water inlet hole 20211 is communicated with the water pump 201. The fog inlet end 2022 is communicated with the fog outlet end 2023. The fog inlet end 2022 is communicated with the atomization chamber 2031. Preferably, the fog inlet end 2022 and the fog outlet end 2023 are communicated through a through hole.

[0030] A seal is fixedly connected to the connection between the atomizing cover 203 and the box body 202 to ensure the sealing performance of the atomizing chamber 2031 and prevent water leakage from the atomizing chamber 2031.

[0031] The water inlet valve 204 is fixedly connected to the box body 202, and the position of the water inlet valve 204 corresponds to the position of the water storage chamber 2021. The water inlet valve 204 is used to control the connection and disconnection between the water storage chamber 2021 and the atomizing chamber 2031. That is to say, after the water inlet valve 204 is opened, the water storage chamber 2021 is communicated with the atomizing chamber 2031, and after the water inlet valve 204 is closed, the water storage chamber 2021 is not communicated with the atomizing chamber 2031.

[0032] The first liquid level switch 207 is used to control at least one of the driving member 205 and the water pump 201. Specifically, the first liquid level switch 207 is used to control at least one of the forward and reverse rotation of the driving member 205 and the connection and disconnection of the water pump 201. Preferably, one end of the first liquid level switch 207 is fixedly connected to the box body 202, and the other end of the first liquid level switch 207 is fixedly connected to the atomizing cover 203. Preferably, please refer to Figure 3 , Figure 3 is Figure 2 the enlarged view of part A in

[0033] Further, please refer to Figure 3-5 , in which, Figure 4 is the three-dimensional view of the water inlet valve in the embodiment, Figure 5Explosion diagram of the water inlet valve in the embodiment. The water inlet valve 204 includes a valve body 2041, a movable member 2042, an elastic element 2043, and a sealing soft body 2044. The valve body 2041 is fixedly connected to the box body 202. The valve body 2041 is provided with a communication hole 20411 for communicating the water storage chamber 2021 with the atomization chamber 2031. One end of the movable member 2042 passes through the communication hole 20411 and is provided with a sealing soft body 2044. The outer diameter of the other end of the movable member 2042 is larger than the outer diameter of the remaining part. One end of the elastic element 2043 abuts against the other end of the movable member 2042, and the other end of the elastic element 2043 abuts against the valve body 2041. The outer diameter of the sealing soft body 2044 is larger than the outer diameter of the communication hole 20411. Under the action of the elastic element 2043, the sealing soft body 2044 abuts against the valve body 2041, so that the sealing soft body 2044 seals the communication hole 20411. The other end of the movable member 2042 is disposed opposite to the driving member 205. The driving member 205 is used to drive the movable member 2042 to move, so as to separate the sealing soft body 2044 from the valve body 2041, and further enable the water in the water storage chamber 2021 to flow from the communication hole 20411 to the atomization chamber 2031. Preferably, one end of the valve body 2041 extends out of the water storage chamber 2021, and the lower edge of the valve body 2041 is at the same horizontal line as the interval position between the first upper reed switch 2072 and the first lower reed switch 2073. Preferably, the elastic element 2043 is a spring, and the sealing soft body 2044 is made of silica gel. Preferably, the water inlet valve 204 further includes a snap ring 2045. The sealing soft body 2044 is sleeved on one end of the movable member 2042, and this end extends out of the sealing soft body 2044, and the snap ring 2045 is provided on this end. Thus, when there is no external force acting on the water inlet valve 204, the elastic element 2043 is in a compressed state, and both ends of the elastic element 2043 abut against the valve body 2041 and the movable member 2042 respectively. The sealing soft body 2044 is in close contact with the valve body 2041, so that the water inlet valve 204 is automatically closed to prevent the water in the water storage chamber 2021 from flowing to the atomization chamber 2031. When the driving member 205 pushes the movable member 2042 upward, the movable member 2042 drives the sealing soft body 2044 to separate from the valve body 2041, so that the water in the water storage chamber 2021 can flow to the atomization chamber 2031.

[0034] Further, please refer to Figure 6 , Figure 6 is Figure 2A second liquid level switch 208 is provided in the water storage chamber 2021. Specifically, one end of the second liquid level switch 208 is fixedly connected to the inner wall of the top of the water storage chamber 2021. The second liquid level switch 208 is used to control at least one of the driving member 205 and the water pump 201. In other words, the second liquid level switch 208 is used to control at least one of the forward and reverse rotation of the driving member 205 and the on and off of the water pump 201. Preferably, the second liquid level switch 208 is a float liquid level switch. Specifically, the float liquid level switch includes a second connecting rod 2081, a limit piece 2082, a second reed switch 2083 and a second float 2084. One end of the second connecting rod 2081 is fixedly connected to the top of the water storage chamber 2021, and the other end of the second connecting rod 2081 is fixedly connected to the limit piece 2082. The second reed switch 2083 is fixedly connected to the second connecting rod 2081, and the second float 2084 is movably connected to the second connecting rod 2081. When the second float 2084 is at the lowest position, the second float 2084 contacts the limit piece 2082, and the position of the second float 2084 coincides with the position of the second reed switch 2083, and the second reed switch 2083 is turned on. When the water level in the water storage chamber 2021 is higher than the second reed switch 2083, the second float 2084 follows the water level and is higher than the second reed switch 2083. That is to say, the position of the second float 2084 is offset from the position of the second reed switch 2083, the second reed switch 2083 is disconnected, and the circuit of the water pump 201 controlled by the second liquid level switch 208 is disconnected. At the same time, the second liquid level switch 208 controls the driving member 205 to move upward, and the driving member 205 pushes the movable member 2042 upward, so that the sealing software 2044 is separated from the connecting hole 20411, so that the water inlet valve 204 is opened, and the water in the water storage chamber 2021 enters the atomization chamber 2031 from the connecting hole 20411. In short, the second liquid level switch 208 makes the water pump 201 stop adding water after the water storage chamber 2021 is filled, and the water in the water storage chamber 2021 flows to the atomization chamber 2031, so as to prevent the water in the water storage chamber 2021 from being overfilled and bursting the water storage chamber 2021.

The diffusion cover 412 is evenly provided with diffusion through holes 4121. The silencer 42 is provided with a silencing air inlet hole 421 and a silencing air outlet hole 422. The silencing air inlet hole 421 is communicated with the oxygen inlet nozzle 3, and the silencing air outlet hole 422 is communicated with the diffusion air inlet hole 4111. Oxygen enters the diffusion groove 4112 and then diffuses into the room through the diffusion through holes 4121, increasing the oxygen content in the room.

[0036] Further, please review Figure 2 , this embodiment further includes a first electromagnetic valve 5. The first electromagnetic valve 5 is respectively communicated with the oxygen inlet nozzle 3 and the silencing air inlet hole 421 through air pipes. Preferably, a throttling copper plug is arranged in the air pipe between the oxygen inlet nozzle 3 and the first electromagnetic valve 5. The first electromagnetic valve 5 is used to control the on-off of the diffusion oxygen outlet part 4. When not in use, the diffusion oxygen outlet part 4 can be cut off by cutting off the first electromagnetic valve 5, avoiding waste of oxygen.

[0037] Further, this embodiment further includes a personal oxygen inhalation part 6. The personal oxygen inhalation part 6 includes a humidifying cup 61 and an oxygen outlet nozzle 62. The humidifying cup 61 is fixedly connected inside the outer shell 1. The humidifying cup 61 is provided with a humidifying air inlet hole 611 and a humidifying air outlet hole 612. The humidifying air inlet hole 611 is communicated with the oxygen inlet nozzle 3, and the humidifying air outlet hole 612 is communicated with the oxygen outlet nozzle 62. The oxygen outlet nozzle 62 is fixedly connected to the outer shell 1, and one end of the oxygen outlet nozzle 62 extends into the outer shell 1, while the other end of the oxygen outlet nozzle 62 extends out of the outer shell 1. The personal oxygen inhalation part 6 flows into the mouth and nose of the human body through the oxygen outlet nozzle 62. Preferably, a breathing mask is fixedly connected to the oxygen outlet nozzle 62. The oxygen of the personal oxygen inhalation part 6 flows from the oxygen outlet nozzle 62 to the breathing mask and then into the mouth and nose. Adding the personal oxygen inhalation part 6 expands the function of the oxygen outlet device. When the human body is severely short of oxygen, oxygen can be quickly inhaled through the personal oxygen inhalation part 6.

[0038] Further, a pressure relief valve 613 is arranged at the top of the humidifying cup 61. When the air pressure in the humidifying cup 61 is too high, the pressure relief valve 613 opens to relieve the pressure, avoiding the rupture of the humidifying cup 61 due to excessive air pressure in the humidifying cup 61.

The second solenoid valve 7 is used to control the on / off of the personal oxygen inhalation part 6. When the personal oxygen inhalation part 6 is not in use, the personal oxygen inhalation part 6 can be cut off by cutting off the second solenoid valve 7, so as to avoid waste of oxygen.

[0040] Further, the atomizing part 2 further includes an atomizing member 209, the atomizing member 209 is rotatably connected to the atomizing end 2023, the atomizing member 209 is provided with an atomizing port 2091, the atomizing port 2091 is communicated with the atomizing end 2023, and the atomizing port 2091 is inclined to the rotating shaft of the atomizing member 209. By rotating the atomizing member 209, the atomizing port 2091 can face any direction, so as to adjust the atomizing port 2091 to the required direction, and then make the mist spray in the required direction.

[0041] Further, a drain switch 210 is detachably connected to the bottom of the atomizing cover 203, and the drain switch 210 extends out of the housing 1. When the oxygen generating device is not used for a long time, the water pump 201 is turned off, the water inlet valve 204 and the drain switch 210 are opened, and the water in the water storage chamber 2021 flows into the atomizing chamber 2031, and the water in the atomizing chamber 2031 is discharged to the outside, so as to discharge the water in the water tank and the atomizing chamber 2031. In this way, when the atomizing chamber 2031 is not used for a long time, the water in the water storage chamber 2021 and the atomizing chamber 2031 is emptied, so as to avoid the water in the water storage chamber 2021 and the atomizing chamber 2031 from generating water stains and polluting the oxygen generating device, thereby improving the sanitary conditions of the atomizing chamber 2031, and further improving the sanitary conditions of the mist discharged by the atomizing member 209, and ensuring the health of the user.

[0042] When the atomizer 206 works, the water in the atomizing chamber 2031 is atomized by the atomizer 206, and the atomized water flows through the mist inlet end 2022 and the mist outlet end 2023 in sequence, and finally flows out from the atomizing port 2091 of the atomizing member 209. When the diffused oxygen supply part 4 works, the first solenoid valve 5 is turned on, oxygen enters from the oxygen inlet nozzle 3, flows into the first solenoid valve 5 and the silencer 42 in sequence, and finally flows out from the diffusing member 41 to the outside.

[0043] When the water level in the atomizing chamber 2031 is low, the first float 2074 overlaps with the first lower reed switch 2073, and the second float 2084 overlaps with the second reed switch 2083, that is, the first lower reed switch 2073 and the second reed switch 2083 are both in a conducting state, the water pump 201 is powered on, and the water pump 201 pumps water into the water storage chamber 2021. At the same time, the driving member 205 pushes the movable member 2042 upward, so that the movable member 2042 drives the sealing software 2044 and the valve 2044 to move. The first float 2074 rises with the water level in the atomizing chamber 2031. As the water level in the atomizing chamber 2031 rises, the first float 2074 is staggered with the first lower reed switch 2073, and the first lower reed switch 2073 is disconnected. The driving member 205 moves downward, and the elastic element 2043 pushes the movable member 2042 to move downward. The sealing member 2042 drives the sealing soft body 2044 to move downward, and the sealing soft body 2044 fits tightly with the valve body 2041, thereby sealing the connecting hole 20411, so that the water inlet valve 204 is closed; the second float 2084 rises with the water level of the water storage chamber 2021. When the second float 2084 and the second reed switch 2083 are staggered, the water storage chamber 2021 is filled with water, the second reed switch 2083 is disconnected, and the water pump 201 stops pumping water. At the same time, the driving member 205 pushes upward The movable part 2042 drives the sealing software 2044 to separate from the valve body 2041, so that the water inlet valve 204 is opened, and the water in the water storage chamber 2021 enters the atomizing chamber 2031 from the connecting hole 20411; when the water level in the atomizing chamber 2031 rises to the lower edge of the valve body 2041 and the valve body 2041 is filled with water, there is no air flow in the valve body 2041, and according to the vacuum principle, the water in the water storage chamber 2021 stops flowing to the atomizing chamber 2031. When the water level in the atomizing chamber 2031 accidentally rises to the first upper reed switch 2072, the first float 2074 overlaps with the first upper reed switch 2072, the first upper reed switch 2072 is turned on, the driving member 205 moves downward, the elastic element 2043 pushes the movable member 2042 to move downward, the movable member 2042 drives the sealing software 2044 to move downward, the sealing software 2044 fits tightly with the valve body 2041, the sealing software 2044 seals the connecting hole 20411, so that the water inlet valve 204 is closed, the water in the water storage chamber 2021 stops entering the atomizing chamber 2031 from the connecting hole 20411, and the water pump 201 is turned off at the same time.

[0044] In summary, when the water level in the atomization chamber is low, the water pump automatically pumps water into the water storage chamber, and the water in the water storage chamber automatically enters the atomization chamber, so that there is always water in the atomization chamber, so that the atomizer can continuously atomize, and then the mist outlet can continuously emit mist.
