1-2 illustrate an electronic atomization device in some embodiments of the present invention, which can be applied to the atomization of a liquid atomizable substrate, which can be roughly flat and includes a flat atomizer 1 and a flat power supply device 2 electrically connected to the atomizer 1 . Wherein, the atomizer 1 includes a liquid storage chamber for accommodating a liquid atomizable substrate and an atomizing assembly 10 connected with the liquid storage chamber for heating and atomizing the liquid atomizable substrate. The atomizing assembly 10 It can usually be installed in the atomizer 1 in a detachable manner. The power supply device is used for supplying power to the atomizing assembly 10 in the atomizer 1 and controlling operations such as turning on or off the entire electronic atomizing device. In some embodiments, the atomizer 1 and the power supply device 2 may be connected together in a detachable manner such as magnetic attraction or screw connection. It can be understood that the electronic atomization device is not limited to be in a flat shape, and can also be in other shapes such as a cylindrical shape, an elliptical cylindrical shape, a square cylindrical shape, and the like.

2-4 show the atomization assembly 10 in the first embodiment of the present invention, and the atomization assembly 10 may include an atomization seat 11 , a first liquid absorbing member 12 and a heating member 13 . In some embodiments, the atomizing seat 11 can be made by an integral molding process such as integral injection molding, integral stamping molding, integral extrusion molding, etc., and it can include a substantially annular base body 111 and is integrally combined with the base body along the longitudinal direction. The round tubular body 112 above the 111. Electrode columns 113 for electrical connection with the heating element 13 may be disposed in the seat body 111 along the longitudinal direction. Generally, an insulating sleeve 114 may be further disposed between the outer ring of the electrode post 113 and the inner ring of the base body 111 to isolate and seal the electrode post 113 and the base body 111 . The top of the tube body 112 can also be tightly embedded with a cylindrical sealing member 115, and the sealing member 115 can usually be made of a flexible material such as silica gel, which is beneficial to improve the sealing performance.

The first liquid absorbing member 12 is a porous structure, which can be cylindrical in some embodiments, and can be disposed in the pipe body 112 along the axial direction. An inner flange 1111 may be integrally formed on the inner wall surface of the top of the base body 111 to extend inwardly, and the first liquid absorbing member 14 may be installed against the upper end surface of the inner flange 1111 in the axial direction. The first liquid absorbing member 12 can usually be a liquid absorbing cotton, and its porosity can be 50%-90%, and the average pore diameter can be 10um-1000um. At least one liquid inlet 1120 is formed on the tube body 112, so that the liquid atomizable substrate in the liquid storage cavity can enter the tube body 112 through the at least one liquid inlet port 1120, so as to connect the first liquid suction member 12 with the storage chamber. The fluid chamber is connected with fluid. In this embodiment, there are four liquid inlets 1120 , and the four liquid inlets 1120 are symmetrically arranged along the circumferential direction of the pipe body 112 .

The first liquid absorbing member 12 has a certain hardness and resilience, so that the first liquid absorbing member 12 can elastically hold the heating element 13 without external force, which is beneficial to realize automatic assembly. Among them, hardness refers to the ability of a material to resist the pressing of hard objects into its surface. If the hardness of the first liquid absorbing member 12 is too hard, it cannot be compressed into the tube body 112 during assembly, and if the hardness is too soft, the heating element 13 cannot be fixed. Therefore, the first liquid absorbing member 12 needs to have a certain hardness. In some embodiments, the hardness of the first liquid absorbing member 12 may be in the range of Shore 20-80A. Resilience represents the ability of an object to deform under the action of an external force and to restore its original size and shape when the external force is removed.

The C-shaped opening of the heating element 13 may be oriented in the same direction as the C-shaped opening of the first liquid absorbing element 12 . The inner wall surface of the first liquid suction member 12 defines a cylindrical atomizing chamber 120, which is used for mixing the atomized smoke with the outside air and communicating with the air outlet channel formed in the atomizer, so as to connect the smoke with the outside air. The mixture of air is exported. It can be understood that, in other embodiments, the cross section of the first liquid absorbing member 12 can also be in other shapes such as a closed circular ring, a closed or square ring with an opening, and the like.

The assembling method of the atomization assembly 10 may include the following steps:

S1 , providing a C-shaped cylindrical first liquid absorbing member 12 , and placing the first liquid absorbing member 12 on the outside of the heating member 13 . Due to the material properties of the first liquid absorbing member 12, after the first liquid absorbing member 12 and the heating element 13 are assembled, the first liquid absorbing member 12 can tightly hold the heating element 13 without external force, thereby There is no need to knead by hand or mechanical fixtures, which is conducive to automatic assembly and reduces labor costs.

S0. Provide a long cylindrical jig and a net-shaped heating element 13, and set the heating element 13 outside the jig.

In step S0, the outer surface of the fixture is a smooth surface, and the frictional force between the smooth surface of the fixture and the heating element 13 is smaller than the frictional force between the heating element 13 and the first liquid absorbing element 12, so after the assembly is completed When the fixture is taken out, the position of the heating element will not be changed. In some embodiments, the jig may be made of metal material, and the frictional force between the fixture and the metal heating element 13 is relatively small. In addition, in step S0, a cylindrical heating element 13 can be directly provided to be sleeved on the outside of the fixture, or, a flat sheet-shaped heating net can be provided and wound around the fixture to form the cylindrical heating element 13 .

In other embodiments, the second liquid absorbing member 16 can also be formed by winding a flat sheet of organic cotton along the heating member 13 . The length of the sheet-shaped organic cotton is longer than the outer circumference of the heating element 13, so that after the sheet-shaped organic cotton is wound outside the heating element 13, the two ends of the sheet-shaped organic cotton can be attached to each other and the attached part has a certain The extension length is easy to hold by hand or mechanical clamps.
