[0037] Please refer to Figure 1 , Figure 2 and Figure 3The first embodiment of the present application provides an electronic atomizer 100, including an atomizing host 10 and a liquid supply component 20. The atomizing host 10 stores and heats the atomizing matrix to generate aerosol for the user to inhale. The liquid supply component 20 stores the atomizing matrix and is used to provide the atomizing matrix for the atomizing host 10. The atomizing host 10 includes an oil cup 11, which is used to accommodate the atomizing matrix; the atomizing host 10 also includes an atomizing component 12 and a power supply 13; the atomizing component 12 is inserted into the oil cup 11 and communicated with the oil cup 11, and the atomizing component 12 can absorb and heat the atomizing matrix in the oil cup 11; the power supply 13 is electrically connected to the atomizing component 12, and is used to power the atomizing component 12 to ensure the electric heating effect of the atomizing component 12 on the atomizing matrix. The electronic atomizer 100 may also include a shell, and the atomizing host 10 and the liquid supply component 20 are assembled in the shell. Liquid storage cotton can be installed in the oil cup 11, a suction nozzle is provided at the top of the oil cup 11, and a microphone assembly and a circuit board are provided at the bottom of the oil cup 11.

[0038] The liquid supply assembly 20 includes a liquid storage tank 21, a liquid supply pipeline 22 and a valve body assembly 23. The component structure is simple and uncomplicated, and the occupied volume is small. The liquid storage tank 21 has a liquid storage chamber 211 for storing liquid atomization matrix. The liquid supply pipeline 22 includes a first end 221 and a second end 222 opposite to each other, the first end 221 is connected to the liquid storage chamber 211, and the second end 222 is connected to the oil cup 11 of the electronic atomizer 100, so that the liquid atomization matrix in the liquid storage chamber 211 can flow into the oil cup 11 via the liquid supply pipeline 22; specifically, the first end 221 can be placed in the liquid storage chamber 211, and at least below the liquid surface when supplying liquid, and the second end 222 of the liquid supply pipeline 22 is placed outside the liquid storage tank 21. The valve body assembly 23 includes a stopper tube 231 and a valve body 232 movable in the stopper tube 231. The stopper tube 231 is connected to the second end 222 and the oil cup 11 respectively. The stopper tube 231 is located in the oil cup 11. The liquid atomized matrix in the liquid supply assembly 20 enters the liquid supply pipe 22 via the first end 221 of the liquid supply pipe 22, flows out from the second end 222, flows into the stopper tube 231, and is finally transported to the oil cup 11 through the stopper tube 231. In order to ensure that the first end 221 is below the liquid surface during liquid supply, the first end 221 can be set at a bottom position close to the liquid storage chamber 211, and in order to shorten the liquid supply path, the liquid supply pipe 22 between the first end 221 and the second end 222 is set as a straight line. The straight line design of the liquid supply pipe 22 reduces the liquid supply path and improves the liquid supply efficiency. The valve body 232 is configured to cut off the communication between the liquid supply pipe 22 and the oil cup 11 when it is close to the second end 222, and is also configured to connect the liquid supply pipe 22 and the oil cup 11 when it is far away from the second end 222. When the electronic atomizer 100 is used for normal suction, the suction effect forms a negative pressure in the oil cup 11 in the atomizer host 10, which causes the valve body 232 to move away from the second end 222, and the liquid supply pipe 22 is connected to the oil cup 11, so that the atomized matrix in the liquid storage tank 21 can be discharged from the second end 222 through the liquid supply pipe 22. Negative pressure sucks the oil cup 11, thereby supplying liquid to the oil cup 11; under the user's suction action, the atomized matrix in the liquid supply component 20 is automatically sucked into the oil cup 11 under the action of negative pressure, thereby realizing automatic liquid supply, and the liquid supply component 20 does not require manual operation by the user to supply liquid; at the same time, when the user stops suctioning, the valve body 232 is not affected by the negative pressure, and is close to the second end 222, thereby cutting off the connection between the liquid supply pipe 22 and the oil cup 11, preventing the atomized matrix in the liquid supply component 20 from entering the oil cup 11, and effectively preventing leakage.

[0039] Since each suction causes the atomized matrix to flow from the liquid storage tank 21 to the oil cup 11, the atomized matrix in the oil cup 11 can maintain a relatively constant amount, thereby making the flow of the atomized matrix from the liquid storage cotton into the atomizing assembly 12 more stable, and overcoming the defect of the flow rate being sometimes large and sometimes small due to the inability of the liquid storage cotton to replenish the atomized matrix in time.

[0040] Please continue reading Figure 2In one embodiment, the limiting tube 231 has an ellipsoidal limiting cavity 2311, that is, the inner walls of the limiting cavity 2311 at both ends of the long axis of the ellipsoid are spherical, and one end of the long axis of the ellipsoid in the limiting cavity 2311 is connected to the liquid supply pipeline 22; the valve body 232 is spherical, which effectively increases the contact area between the valve body 232 and the inner wall of the limiting cavity 2311, and can improve the blocking effect of the valve body 232 on the connection port between the limiting cavity 2311 and the liquid supply pipeline 22; the diameter of the valve body 232 is smaller than the short axis of the ellipsoid, which ensures that the valve body 232 can move in the limiting cavity 2311, and the valve body 232 and the limiting cavity 2311 are connected to one end of the liquid supply pipeline 22 When the inner wall is in contact, the connection between the liquid supply pipe 22 and the oil cup 11 can be blocked. Under the negative pressure in the atomizing cup, the valve body 232 moves in a direction away from the liquid supply pipe 22, so that the liquid supply pipe 22 and the oil cup 11 are connected, and then the atomized matrix in the liquid storage tank 21 is sucked into the oil cup 11 under negative pressure, so as to achieve the automatic liquid supply effect. At the same time, the atomized matrix passes through the gap formed between the valve body 232 and the ellipsoidal limiting cavity 2311. Since the size of the gap space is fixed, the valve body 232 and the limiting cavity 2311 form a stabilizing effect on the atomized matrix delivery flow, so that the atomized matrix flow delivered through the limiting tube 231 is relatively constant. The surface of the valve body 232 can be specially treated, such as electroplating or coating, to increase its friction with the inner wall of the limiting tube 231 and improve the blocking effect.

[0041] Please refer to Figure 3 and Figure 4 In another embodiment, the limiting tube 231 has a limiting cavity 2311, and the limiting cavity 2311 includes an inlet end 2312 and an outlet end 2313. The inlet end 2312 is connected to the liquid supply pipeline 22, and the outlet end 2313 is connected to the oil cup 11. The cross-sectional area of ​​the limiting cavity 2311 gradually increases from the inlet end 2312 to the outlet end 2313, so as to ensure that the valve body 232 can block the connection between the liquid supply pipeline 22 and the oil cup 11 when it is close to the inlet end 2312, and can realize the connection between the liquid supply pipeline 22 and the oil cup 11 when the valve body 232 is far away from the inlet end 2312 or close to the outlet end 2313. The limiting cavity 2311 is in a truncated cone shape, and the valve body 232 is in a spherical shape. The diameter of the valve body 232 is larger than the cross-sectional diameter of the inlet end 2312 and smaller than the cross-sectional diameter of the outlet end 2313, so that the valve body 232 can not only block the inlet end 2312 at the inlet end 2312, but also block the outlet end 2313 at the outlet end 2313, so that when the electronic atomizer 100 is inverted, the valve body 232 is close to the outlet end 2313, blocking the limiting cavity 2311 from being connected with the oil cup 11, preventing the atomized matrix in the liquid supply assembly 20 from entering the oil cup 11, and effectively preventing leakage.

[0042] Further, in order to improve the blocking effect of the valve body 232 on the outlet end 2313, the density of the valve body 232 can be set to be greater than the density of the atomized matrix in the liquid storage chamber 211, so that the electronic atomizer 100 moves to the outlet end 2313 to block the outlet end 2313 because the density of the valve body 232 is greater than the density of the atomized matrix, making it difficult for the atomized matrix in the liquid storage chamber 211 to be discharged from the outlet end 2313. At the same time, the dead weight of the atomized matrix is ​​also applied to the valve body 232, thereby further blocking the outlet end 2313 by the valve body 232, making it more difficult for the atomized matrix to be discharged from the outlet end 2313. In this embodiment, the valve body 232 can be made of metal, preferably stainless steel, which has good corrosion resistance, prolongs the service life of the product, and reduces the generation of waste.

[0043] Please continue to refer to Figure 2 and Figure 3 Furthermore, the liquid storage tank 21 also includes a pressure relief portion 212, which is used to balance the air pressure of the liquid storage chamber 211 and the outside, and ensure that the atomized matrix in the liquid storage chamber 211 can be smoothly sucked into the oil cup 11 through the liquid supply pipe 22 under the negative pressure in the oil cup 11, so as to realize automatic liquid supply. The pressure relief portion 212 can be located at the top of the liquid storage tank 21, so that when the electronic atomizer 100 is in normal use, the pressure relief portion 212 is at the top, which is convenient for balancing the internal and external air pressures. The pressure relief portion 212 is a one-way air inlet, which is an inverted conical through hole with a narrow inside and a wide outside, so that the outside air can enter the liquid storage tank 21 from the outside of the liquid storage tank 21, that is, the outside air can enter through the large end of the inverted conical through hole and flow into the liquid storage chamber 211 from the small end; while the atomized matrix stored in the liquid storage tank 21 cannot easily enter from the small end of the inverted conical through hole and flow out of the liquid storage chamber 211, effectively preventing leakage. When negative pressure is generated outside the second end 222 of the liquid supply pipeline 22, the air of the one-way air inlet will enter the liquid storage tank 21, so that the atomized matrix in the liquid storage tank 21 enters the liquid supply pipeline 22 from the first end 221, and due to the air pressure, the atomized matrix is ​​transported from bottom to top in the liquid supply pipeline 22, and then flows out from the second end 222 to complete the liquid supply function of the liquid supply pipeline 22. In addition, the pressure relief portion 212 can also adopt a one-way air inlet valve such as a valve core. In order to improve the one-way valve function of the one-way air inlet, the one-way air inlet is made of soft materials, such as silica gel, which can better realize the one-way air inlet from the one-way air inlet to allow air to enter and the atomized matrix cannot be discharged from the one-way air inlet. At the same time, the inverted cone design of the one-way air inlet helps to reduce the condensation of water in a high humidity environment and keep the inside of the liquid storage tank 21 dry. The shape of the liquid storage tank 21 can be columnar, such as cylindrical, to reduce the fluctuation of the internal liquid and improve the stability of the liquid supply.

[0044] The working principle of the electronic atomizer 100 of this embodiment is as follows: when the user inhales through the suction nozzle, negative pressure is generated at the suction nozzle, and air enters the liquid storage tank 21 through the one-way air inlet hole. The atomized matrix is ​​sucked to the valve body 232 through the liquid supply pipe 22 under the action of air, and the valve body 232 at the inlet end 2312 of the limiting tube 231 is pushed open, and the atomized matrix enters the limiting tube 231, and then flows from the outlet end 2313 to the oil cup 11, and the atomized matrix is ​​absorbed and stored by the liquid storage cotton located in the oil cup 11, and the atomized matrix flows to the atomizing component 12 through the liquid storage cotton; while negative pressure is generated at the suction nozzle, the microphone component is activated after sensing the pressure difference change, so that the atomizing component 12 is powered on and heated to start atomizing to generate aerosol.

[0045] In one embodiment, liquid can be supplied to the oil cup 11 by squeezing the liquid storage tank 21; the liquid storage tank 21 is made of elastic material, which deforms when squeezed, so that the volume of the liquid storage cavity 211 becomes smaller, prompting the atomized matrix to enter the liquid supply pipeline, pushing the valve body 232 open, and the valve body 232 moves away from the second end 222 to connect the liquid supply pipeline 22 and the oil cup 11, and the atomized matrix finally enters the oil cup 11, so that liquid is supplied to the oil cup 11.

[0046] Please continue to refer to Figure 2 , Figure 3 and Figure 4In one embodiment, the position limiting tube 231 can be connected to the liquid supply pipe 22 by threaded connection, plug connection, or welding connection, so as to ensure that the liquid supply pipe 22 is connected to the oil cup 11 via the position limiting tube 231, and to ensure that the position limiting tube 231 cooperates with the valve body 232 to effectively control whether the liquid supply pipe 22 is connected to the oil cup 11. Through the threaded connection, the position limiting tube 231 can be removed, which is convenient for the installation of the valve body 232. The position limiting tube 231 can be composed of two cavities. Specifically, the position limiting tube 231 is composed of a first cavity split 2314 and a second cavity split 2315. The second cavity body 2315 is connected and fixed to the second end 222 of the liquid supply pipe 22, or is made in one piece; the outer diameter of the second cavity body 2315 is larger than the outer diameter of the second end 222. This structure can also help limit the depth of the liquid supply pipe 22 inserted into the liquid storage tank 21, so that the first end 221 of the liquid supply pipe 22 remains suspended for easy liquid absorption. If the liquid supply pipe 22 lacks a limit, the straight liquid supply pipe 22 will directly contact the bottom surface of the liquid storage tank 21, and there will be no gap space between the first end 221 and the inner wall of the liquid storage cavity 211 for liquid absorption; the first cavity body 2314 and the second cavity body 2315 are assembled into a complete limiting tube 231 through threaded connection. The position of the liquid supply pipe 22 can also be limited by other structures, such as a limiting groove with a liquid absorption gap at the bottom of the liquid storage tank 21, or a limiting convex edge is directly formed on the outer surface of the liquid supply pipe 22. The first cavity split 2314 and the second cavity split 2315 of this embodiment adopt a structure that is split along the axial direction of the liquid supply pipe 22. The first cavity split 2314 and the second cavity split 2315 can also be made of metal material and assembled by ultrasonic welding, or by gluing, or by snap-fitting, and sealed with a sealing ring, interference fit, etc.; the first cavity split 2314 and the second cavity split 2315 are not limited to the structural assembly shown in this embodiment. The liquid supply pipe 22 can also be divided into a first liquid supply sub-channel and a second liquid supply sub-channel divided along the diameter, the first cavity split 2314 and the first liquid supply sub-channel are an integrated structure, the second cavity split 2315 and the second liquid supply sub-channel are an integrated structure, and the two are assembled to form a complete limit tube 231 and liquid supply pipe 22.
