Fig. 1 is a schematic view of an electronic atomizer according to an exemplary embodiment of the present disclosure.

As shown in fig. 1, the electronic atomizer 100 includes an atomizer 10 and a power supply module 20, and the atomizer 10 is formed integrally with the power supply module 20.

In other examples, the nebulizer 10 is removably connected to the power supply assembly 20, e.g., a snap-fit connection, a magnetic connection; but also possible.

The atomizer 10, under the influence of electrical power provided by the power supply assembly 20, heats an atomized liquid substrate to generate a smokable aerosol.

The power supply assembly 20 includes a battery cell 21 and a circuit 22.

The battery cell 21 supplies power for operating the electronic atomization device 100. The battery cell 21 may be a rechargeable battery cell or a disposable battery cell.

The circuit 22 may control the overall operation of the electronic atomization device 100. The circuit 22 controls operation of not only the cell 21 and the atomizing assembly 11, but also other components of the electronic atomizing device 100.

Fig. 2-4 are schematic exploded and cross-sectional views of an atomizer as provided in an example of the present application.

As shown in fig. 2-4, the atomizer 10 provided in the present embodiment includes a nozzle assembly 101, an atomizer housing 102, a sleeve 103, a glass fiber tube 104, a heating assembly 105, and a base 106.

The nozzle assembly 101 is mounted at an opening at the upper end of the atomizer housing 102. The nozzle assembly 101 includes a mouthpiece 101a and a sealing member 101b. The mouthpiece 101a is arranged coaxially with the sealing member 101b and part of the aerosol passage formed by the mouthpiece assembly 101 extends through the mouthpiece 101a and the sealing member 101b. The mouthpiece 101a is disposed in a recess in the seal 101b with its upper end horizontally aligned with the upper end face of the seal 101b. A seal 101b is provided between the mouthpiece 101a and the atomizer housing 102 to form a seal.

The atomizer housing 102 is substantially cylindrical and has openings at both ends. The interior of the atomizer housing 102 is formed with a reservoir chamber a for storing a liquid substrate. The atomizer housing 102 and the power supply component housing (not shown) together define or form a housing of the electronic atomizer device 100.

The sleeve 103 is sleeved outside the glass fiber tube 104 to hold the glass fiber tube 104. The sleeve 103 has an axial dimension less than the axial dimension of the glass fiber tube 104. The lower end of the sleeve 103 is received in the seat 106. The lower end of the sleeve 103 has a cutaway slot (not shown) so that the laterally disposed capillary wick 1051 can snap into the cutaway slot.

As will be understood from fig. 5, the upper end of the glass fiber tube 104 is sleeved on the sealing element 101b, and the lower end of the glass fiber tube 104 is sleeved on the base 106. The glass fiber tube 104 is provided with a notch 1041 and a clamping groove 1042. A portion of the glass fiber tube 104 may be bent toward one side along the incision 1041, thereby exposing the slot 1042.

As will be understood in conjunction with fig. 6, the heating element 105 includes a capillary wick 1051, a heating element 1052, a first lead 1053, and a second lead 1054.

The capillary wick 1051 draws the liquid matrix in the reservoir a by capillary action. The wick 1051 can be made of, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc., and is preferably made of cotton fiber. The capillary wick 1051 is arranged inside the atomizer housing 102 along the transverse direction of the electronic atomizer 100. The capillary wick 1051 is laterally disposed in the clamping groove 1042, and both ends thereof can extend into the reservoir a to suck the liquid medium in the reservoir a. Further, a liquid storage member (not shown) for locking the liquid matrix, such as a liquid cotton, may be disposed in the liquid storage chamber a, and both ends of the capillary core 1051 may be in contact with the liquid storage member to suck the liquid matrix in the liquid storage chamber a.

The heating element 1052 is used to heat the liquid substrate drawn by the capillary wick 1051 to generate an aerosol. The heating element 1052 is preferably an electrical resistance heating element, such as an electrical resistance heating wire. The heating element 1052 is wound around the capillary wick 1051 and is placed with a portion of the capillary wick 1051 in the portion of the aerosol channel formed by the glass fiber tube 104.

The first lead 1053 and the second lead 1054 are used to electrically connect the heating element 1052 and the cell 21. One end of the first lead 1053 is connected to the heating element 1052, for example, welded to the heating element 1052, and the weld B is preferably located in the portion of the aerosol path formed by the glass fiber tube 104; the other end of the first lead 1053 extends out of the base 106 through the through hole 1061 of the base 106 to be electrically connected to other parts, for example, the battery cell 21. The second lead 1054 is similar to the first lead 1053, and extends out of the base 106 through the via 1062 of the base 106 at the other end.

Since the first lead 1053 and the second lead 1054 are both easily moved, such as toward the mouth end of the electronic atomizer 100, during assembly, the heating element 1052 is displaced, causing problems such as dry burning. To avoid this problem, the lead has a stopper portion having a radial dimension larger than that of the other positions of the lead, the stopper portion being capable of preventing the lead from being pulled when received into the via 1061.

For example, in a preferred embodiment, the first lead 1053 includes a connection portion C disposed between two ends thereof, the connection portion C is disposed between the first portion lead 1053a and the second portion lead 1053b, and the connection portion C may be a bump formed by soldering, thereby defining the position-limiting portion. In other examples, it is also possible to spot-weld the connection portion C directly on one entire first lead 1053. The radial dimension of the connecting portion C is larger than the radial dimension of the first partial lead 1053a or the second partial lead 1053 b. The connecting portion C prevents the first lead 1053 from being pulled when received in the through hole 1061.

Of course, the form of the connection portion C is not limited to the case shown in fig. 6. As shown in fig. 7, the connecting portion C includes a connecting member for connecting the first partial lead 1053a and the second partial lead 1053b, and the connecting member may be, for example, a member having a cross-sectional shape similar to a butterfly or an arch formed by bending opposite sides of the substrate, and then connecting the ends of the first partial lead 1053a and the second partial lead 1053b by caulking.

In other examples, it is also possible that the radial dimension of the second partial lead 1053b is larger than the radial dimension of the first partial lead 1053a, and at least a portion of the second partial lead 1053b defines the stopper.

Further, a partition wall 1061a is provided in the via hole 1061. The thickness of the partition wall 1061a is small, so that the other end of the first lead 1053 can pierce the partition wall 1061a and extend out of the base 106, and the stopper is retained in the through hole 1061 after passing through the partition wall 1061a. In this way, the punctured partition wall 1061a can block the stopper from moving toward the mouth end of the electronic atomizer 100.

In a preferred embodiment, the partition wall 1061a is disposed near the lower end of the through hole 1061, i.e., the distance between the partition wall 1061a and the lower end of the through hole 1061 is less than the distance between the partition wall 1061a and the upper end of the through hole 1061. The radial dimension of the limiting part is smaller than the aperture of the partial through hole 1061 between the partition wall 1061a and the upper end of the through hole 1061, but is larger than the aperture of the partial through hole 1061 between the partition wall 1061a and the lower end of the through hole 1061, that is, the aperture of the partial through hole 1061 between the partition wall 1061a and the upper end of the through hole 1061 is larger than the aperture of the partial through hole 1061 between the partition wall 1061a and the lower end of the through hole 1061; thus, the cost of punching the base 106 can be reduced, and the first lead 1053 can pass through the base 106.

Similarly, the second lead 1054 is configured similar to the first lead 1053, and the via 1062 is configured similar to the via 1061 to prevent the second lead 1054 from being pulled when received in the via 1062.

As will be appreciated in conjunction with fig. 8-9, the base 106 also includes a hollow tube 1063. The through holes 1061 and 1062 are symmetrically disposed on both sides of the hollow tube 1063. The hollow tube 1063 forms part of the aerosol channel in the hollow part, and the upper end of the hollow tube 1063 protrudes from the upper surface of the base 106. Thus, the lower end of the glass fiber tube 104 can be sleeved on the hollow tube 1063. After entering the hollow tube 1063, the external air flows through the heating assembly 105 and flows out of the partial aerosol passage formed by the mouthpiece assembly 101 together with the aerosol generated by the heating assembly 105.

The base 106 fits within an opening at the lower end of the atomizer housing 102 and extends partially into the atomizer housing 102. The peripheral sidewall of the base 106 has a raised ring 1064, and the raised ring 1064 is in contact with the inner surface of the atomizer housing 102 to seal the reservoir a.

The base 106 also has a protruding support 1065 on the peripheral side wall thereof, and the end of the lower end of the atomizer housing 102 is held on the support 1065.
