The atomizing component is installed inside the oil cup, which forms a liquid storage chamber 11. The liquid supply device and the vacuum device 2 are respectively connected to the liquid storage chamber 11.

[0034] In some embodiments, the housing 1 includes a separable first housing 101 and a second housing 102. The first housing 101 is provided with a suction nozzle, a liquid storage chamber 11 and an atomizing chamber are disposed in the first housing 101, and the suction nozzle communicates with the atomizing chamber. The second housing 102 defines and forms a liquid chamber 12 inside.

[0035] like Figure 2 As shown, the arrows indicate the direction of fluid flow, indicating that the fluid can pass through the liquid chamber 12, the storage chamber 11, and the vacuum device 2 in sequence. The fluid mentioned here can be an atomized matrix or air, or other substances stored in the liquid chamber 12 that can flow.

[0036] Understandably, a fluid channel 31 is provided between the liquid storage chamber 11 and the liquid reservoir 12.

The sealing seat 3 is provided with a fluid channel communicating with the liquid storage chamber 11. The first injection tube 14 can be inserted into the fluid channel, and the end of the first injection tube 14 inserted into the liquid storage chamber 11 is close to the center of the liquid storage chamber 11. The first injection tube 14 can be higher than the bottom of the liquid storage chamber 11 by a certain distance to retain a certain amount of atomized matrix in the liquid storage chamber 11 and prevent the atomized matrix injected into the liquid storage chamber 11 from flowing back to the liquid tank 12.

[0039] In some embodiments, the second shell 102 is provided with a second liquid injection pipe 13 extending into the liquid tank 12, one end of the second liquid injection pipe 13 extending into the liquid tank 12 through the second shell 102 and being close to the bottom of the liquid tank 12, and the other end of the second liquid injection pipe 13 being exposed outside the second shell 102 and being connected with the first shell 101 to communicate with the liquid storage cavity 11. It can be understood that the second liquid injection pipe 13 can define at least a part of the fluid passage 31, and the second liquid injection pipe 13 and the first liquid injection pipe 14 can be communicated when the first shell 101 and the second shell 102 are connected.

[0040] In some embodiments, the vacuum device 2 and the liquid storage cavity 11 are provided with a gas passage 4, and the gas passage 4 is provided with a first one-way valve 5 for allowing air to be released from the liquid storage cavity 11 to outside the liquid storage cavity 11 to form a negative pressure state in the liquid storage cavity 11.

[0041] The vacuum device 2 is installed in the shell 1, and the vacuum device 2 includes a third shell 22 capable of being installed on the shell 1, an elastic membrane 23, and a driving source.

[0042] One end of the third shell 22 is provided with an opening, the elastic membrane 23 is installed at the opening, the third shell 22 and the elastic membrane 23 jointly define an air chamber capable of containing air, the gas passage 4 is arranged on the third shell, and the third shell is further provided with an air hole communicating with the outside of the electronic atomizer, the elastic membrane 23 is driven by the driving source to discharge air to outside the shell 1, so that a negative pressure is formed in the third shell 22, and the air in the liquid storage cavity 11 is extracted by the negative pressure to form a negative pressure state in the liquid storage cavity 11.

[0043] As shown in Figure 2 The shell 1 is provided with a pump 21, and the third shell 22 and the elastic membrane 23 jointly constitute a pump shell of the pump 21, the pump 21 is provided with two air holes, one of which communicates with the liquid storage cavity to form the gas passage 4, and the other of which communicates with the outside of the electronic atomizer.

[0044] The elastic membrane 23 is made of rubber or silicone material, and the initial state of the elastic membrane 23 is outwardly convex, the elastic membrane 23 can compress the volume of the third shell 22 when being pressed, and the air in the third shell 22 is discharged from the air hole as shown by the curved arrow in Figure 2 When the elastic membrane 23 returns, the volume of the third shell 22 increases, and under the condition that the air in the third shell 22 decreases, a negative pressure state is formed in the third shell 22.

[0045] It can be understood that the liquid storage cavity 11 is in communication with the atomization cavity, and the atomization cavity is in communication with the external atmosphere. When a negative pressure is formed in the third shell 22, the external atmosphere can enter the atomization cavity, and then the air in the liquid storage cavity 11 is supplemented into the third shell 22, so that the air pressure in the third shell 22 is restored to a state of balance with the external air pressure. When the air pressure in the third shell 22 is greater than or equal to the air pressure in the liquid storage cavity 11, the first one-way valve 5 is forced to close the gas passage 4, and the air in the liquid storage cavity 11 cannot be extracted into the third shell 22. When the air pressure in the third shell 22 is less than the air pressure in the liquid storage cavity 11, the air in the liquid storage cavity 11 drives the first one-way valve 5 to open the gas passage 4, so that the liquid storage cavity 11 is in communication with the third shell 22. The air in the liquid storage cavity 11 is extracted into the third shell 22, and the liquid storage cavity 11 forms a negative pressure due to the reduction of air. The liquid matrix in the liquid tank 12 is atomized into liquid particles and is sprayed out of the third shell 22 through the atomization cavity. Figure 2 As shown by the straight-line arrows indicated in the middle longitudinal direction, the liquid matrix is sucked into the liquid storage cavity 11.

[0046] In some embodiments, a second one-way valve 28 is arranged on the air hole, and the second one-way valve 28 is used to allow the air in the third shell 22 to be released to the outside of the third shell 22, so that the third shell 22 forms a negative pressure state to extract the air in the liquid storage cavity 11.

[0047] In some embodiments, as shown in Figure 2 The driving source includes an electromagnet 24 and a magnetic piece 25. The magnetic piece 25 is fixed on the elastic membrane 23. The electromagnet 24 is used to generate a magnetic attraction force in an energized state, and the magnetic piece 25 is attracted close to the electromagnet 24 by the magnetic attraction force to drive the elastic membrane 23 to extract the air in the liquid storage cavity 11. When the electromagnet 24 is in a de-energized state, the magnetic attraction force disappears, the magnetic piece 25 is released and moves away from the electromagnet 24, and the elastic membrane 23 is reset to cause the air in the third shell 22 to be compressed to break the closure of the second one-way valve 28. The air is discharged to the outside of the third shell 22, the third shell 22 forms a negative pressure state, and the air in the liquid storage cavity 11 is extracted into the third shell 22.

[0048] In some embodiments, as shown in Figure 3 Figure 3 The driving source includes a motor 26 and a cam 27. The motor 26 has a rotating shaft outputting rotary power, and the cam 27 has at least one protruding convex part. The rotating shaft of the motor 26 is connected with the cam 27, and the convex part on the cam 27 intermittently hits the elastic membrane 23 when the motor 26 rotates. When the elastic membrane 23 is hit, the air in the third shell 22 is discharged from the second one-way valve 28, the air pressure in the third shell 22 is reduced to form a negative pressure state, the air in the liquid storage cavity 11 is extracted into the third shell 22 through the first one-way valve 5, and the air is discharged when the cam 27 next hits the elastic membrane 23.

[0049] Compared with the prior art, the electronic atomizer described in the application can change the air pressure of the liquid storage cavity 11 through the vacuum device 2, use negative pressure to suck the atomized substrate in the liquid bin 12 to the liquid storage cavity 11, and the user can also start or stop the vacuum device 2 according to needs to control the amount of atomized substrate extracted.
