In other embodiments, the atomizing matrix 21 may also include only a sleeve structure, and the sleeve is used to plug in the atomizing matrix. The heating body 22 heats the plugged atomizing matrix to form smoke.

[0045] In this embodiment, the heater 22 may be connected to a positive electrode lead 221 and a negative electrode lead 222 . The positive electrode lead 221 and the negative electrode lead 222 may extend to be electrically connected to the circuit board 4 .

[0047] The display screen 31 is a flexible screen that can be bent and deformed. The flexible screen can be distributed on a curved outer surface of the housing 1. The flexible screen can also extend to multiple outer sides of the housing 1, such as Figure 1 and Figure 2 As shown, the flexible screen can extend from the first outer side surface of the housing 1 to the second outer side surface and the third outer side surface of the housing 1, wherein the first outer side surface, the second outer side surface and the third outer side surface of the housing 1 are sequentially connected surfaces, wherein the first outer side surface and the second outer side surface are opposite to each other, and the connection between the first outer side surface, the second outer side surface and the third outer side surface can be bent. The flexible screen can also be formed into a ring to wrap around the four outer side surfaces of the housing 1.

[0048] The display screen 31 is set as a flexible screen, so that the display screen 31 can adapt to the appearance of different products, and the shape is better and more beautiful. The structure of the flexible screen is thinner, which can reduce the occupied space. The flexible screen can cover more outer sides, display more information, and is easy to use for viewing, which can improve the user experience.

[0049] In other embodiments, the display screen 31 may also be a common display screen, and the common display screen, the screen control panel 32 and the first connector 33 may also be combined into a modular structure, which may be installed on an outer side of the housing 1 .

[0050] In this embodiment, the screen control panel 32 and the display screen 31 are arranged side by side, and the screen control panel 32 and the display screen 31 can be laid flat on the outer side of the housing 1, so that the installation of the display screen 31 and the screen control panel 32 is convenient. The first connector 33 can be arranged on the screen control panel 32, and the first connector 33 can be arranged on the front of the screen control panel 32, the back of the screen control panel 32 is the surface facing the housing 1, and the front of the screen control panel 32 is the surface facing away from the housing 1. The first connector 33 is located on the front of the first connector 33, which is convenient for the plugging of the circuit board 4 and the first connector 33.

[0051] In other embodiments, the screen control panel 32 may also be disposed on the back of the display screen 31, with a portion of the screen control panel 32 extending out of one side of the display screen 31, and the first connector 33 installed on the portion of the screen control panel 32 extending out of one side of the display screen 31. This structure may also form an integrated modular structure, which is facilitating the installation of the display screen assembly 3.

[0052] In this embodiment, the outer side surface of the housing 1 is provided with a first accommodating groove 11 and a second accommodating groove 12 arranged side by side. The first accommodating groove 11 can extend to multiple outer side surfaces of the housing 1. The distribution of the first accommodating groove 11 corresponds to the distribution of the display screen 31. Figure 4 As shown, the first receiving groove 11 is distributed on the first outer side surface, the second outer side surface and the third outer side surface of the housing 1 to form a C-shaped curved distribution. The second receiving groove 12 is disposed on the first outer side surface of the housing 1, and a communicating gap is provided between the first receiving groove 11 and the second receiving groove 12.

[0053] The shape and size of the first receiving groove 11 are adapted to the display screen 31. The display screen 31 is installed in the first receiving groove 11. The four edges of the display screen 31 are close to or in contact with the four side walls of the first receiving groove 11, so as to reduce the gap between the first receiving groove 11 and the display screen 31, and to achieve the position limitation of the first receiving groove 11 on the display screen 31, and to improve the aesthetics. The shape and size of the second receiving groove 12 are adapted to the screen control panel 32. The screen control panel 32 is installed in the second receiving groove 12.

[0054] The depth of the first accommodating groove 11 is equal to or approximately equal to the thickness of the display screen 31, and the depth of the second accommodating groove 12 is equal to or approximately equal to the thickness of the screen control panel 32, so that after the display screen 31 and the screen control panel 32 are respectively installed in the first accommodating groove 11 and the second accommodating groove 12, the front of the display screen 31 and the screen control panel 32 can be flush with the outer side surface of the shell 1, which is more beautiful and can also play a role in hiding and protecting the display screen 31 and the screen control panel 32.

[0055] In other embodiments, one or both of the display screen 31 and the screen control panel 32 may also be directly mounted on the outer surface of the housing 1 , and the installation of the display screen 31 and the screen control panel 32 may also be achieved.

[0056] In this embodiment, the back side of the display screen 31 can be adhered to the first accommodating groove 11 by double-sided foam 3M glue or other adhesives. The display screen 31 is a flexible screen, and double-sided foam 3M glue or other adhesives are also flexible adhesive structures, so that double-sided foam 3M glue or other adhesives can be bent together with the flexible screen and fit the shell 1. When the shape and area of ​​double-sided foam 3M glue or other adhesives are the same as those of the flexible screen, double-sided foam 3M glue or other adhesives can bond and fix the entire area of ​​the flexible screen, ensuring that the flexible screen can be stably fixed on multiple outer surfaces of the shell 1.

[0057] In other embodiments, the flexible screen may also be bonded and fixed to one or more outer surfaces of the shell 1 by adhesive materials such as liquid, semi-liquid or solid glue to achieve a fixed connection between the flexible screen and the shell 1.

[0058] In this embodiment, the screen control panel 32 can also be fixed in the second receiving groove 12 by using double-sided foam 3M adhesive or other adhesive. Since the screen control panel 32 is a flat structure, the screen control panel 32 can also be fixedly connected to the housing 1 by means of snap connection, screw connection, etc.

[0059] In this embodiment, the screen control panel 32 is electrically connected to the display screen 31 and the first connector 33 respectively. The screen control panel 32 is used to control the display content of the display screen 31, and the first connector 33 is used to be electrically connected to the circuit board 4. By incorporating the screen control panel 32 into the display screen assembly, the display screen assembly 3 can control the display, making it easier to combine the display screen assembly 3 with other products and adapt to the circuit boards of other products, thereby improving the expandability and compatibility of the display screen assembly 3.

[0060] The first connector 33 may be a connection structure such as a socket with a socket, and the circuit board 4 may be plugged into the first connector 33 through a flexible flat cable 6 (abbreviated as FPC). The housing 1 may be provided with an escape opening 13, one end of the flexible flat cable 6 is connected to the circuit board 4, and the other end of the flexible flat cable 6 passes through the escape opening 13 of the housing 1 and is plugged into the first connector 33.

[0061] In this embodiment, the second accommodating groove 12 can be set at a position close to the lower cover 1c, the screen control panel 32 is located on one side of the display screen 31 closer to the lower end, the circuit board 4 is installed at the bottom of the shell 1, and the avoidance opening 13 can be set close to the second accommodating groove 12, so that one end of the flexible flat cable 6 passes through the avoidance opening 13 and extends a shorter distance to connect with the first connector 33, which can reduce the length of the flexible flat cable 6, reduce costs and improve transmission stability.

[0062] In other embodiments, the circuit board 4 may be disposed close to the first connector 33 , and the circuit board 4 may be provided with plug-in terminals such as plugs, which are plugged into the first connector 33 to form an electrical connection.

[0063] In other embodiments, the first connector 33 may also be a conductive magnetic terminal, and the circuit board 4 may be magnetically connected to the first connector 33 through an electrical connection structure such as a magnetic flexible flat cable to form an electrical connection.

[0064] In this embodiment, the installation of the electronic atomization device mainly includes the following three steps:

[0065] Step 1: Install the atomizer core 2, atomizer bin 5, circuit board 4 and other components in the housing 1, and lead one end of the flexible flat cable 6 connected to the circuit board 4 out of the escape opening 13 of the housing 1 to the outside of the housing 1;

[0066] Step 2: fix the display screen 31 in the first receiving groove 11 by bonding, and fix the screen control panel 32 in the second receiving groove 12 by bonding or other means;

[0067] Step 3: One end of the flexible flat cable 6 passing through the avoidance opening 13 is plugged into the first connector 33 to complete the assembly of the electronic atomization device.

[0068] The first and second steps can also be interchanged, that is, the display screen assembly 3 is first installed on the outer side of the shell 1, and then the atomizer core 2, the atomizer bin 5 and the circuit board 4 are installed in the shell 1.

[0069] Of course, the electronic atomization device may also include other components, such as a transparent shell or the like, which is sleeved on the outer side of the housing 1 to protect the display screen assembly 3. The transparent shell may be sleeved on the outer side of the housing 1 in the final installation step to achieve installation.

[0070] The electronic atomization device of this embodiment connects the display screen 31, the screen control panel 32 and the first connector 33 into an integrated display screen assembly 3; during installation, the display screen assembly 3 and the circuit board 4 can be installed on the housing separately, and then the circuit board 4 can be connected to the first connector 33 of the display screen assembly 3. This fixed connection method greatly facilitates the assembly of the electronic atomization device. In addition, the display screen assembly 3 forms a modular structure with a screen control panel 2, which makes the display screen assembly 3 more expandable and compatible, and can be easily applied to other types of electronic atomization devices, effectively reducing the development cost of other products.

The first through hole 71a and the second through hole 72a are perpendicular to the circuit board 4 and penetrate the first base 7a. The circuit board 4 is provided with a positive terminal 42 and a negative terminal 43 perpendicular to the circuit board 4. The positive terminal 42 is provided in the first through hole 71a, and the end of the positive terminal 42 passes through and is exposed in the first through hole 71a; the negative terminal 43 is provided in the second through hole 72a, and the end of the negative terminal 43 passes through and is exposed in the second through hole 72a.

[0087] The circuit board 4 may be provided with a through hole, and a portion of the first base 7a passes through the through hole of the circuit board 4, and a portion of the first base 7a passing through the circuit board 4 forms a vent.

[0088] The second base 7b can be fixed to one end of the atomization bin 5 by bonding, clamping, etc., and a mounting hole 73b is provided in the second base 7b, and one end of the atomization core 2 is inserted into the mounting hole 73b. The second base 7b can be provided with a first plug hole 71b and a second plug hole 72b, and the openings of the first plug hole 71b and the second plug hole 72b are facing away from the atomization bin 5 and toward the first base 7a. The positive lead 221 of the heating body 22 passes through the mounting hole 73b and bends to extend into the first plug hole 71b, and the negative lead 222 of the heating body 22 passes through the mounting hole 73b and bends to extend into the second plug hole 72b.

[0089] The first insertion hole 71b is axially aligned with the first through hole 71a, and the end of the positive terminal 42 is inserted into the first insertion hole 71b to contact and connect with the positive lead 221; the second insertion hole 72b is axially aligned with the second through hole 72a, and the end of the negative terminal 43 is inserted into the second insertion hole 72b to contact and connect with the negative lead 222.

[0090] In this embodiment, the first plug hole 71b and the second plug hole 72b are configured as blind holes, which can prevent the first plug hole 71b and the second plug hole 72b from penetrating the second base 7b and affecting the sealing of the liquid storage cavity, thereby preventing leakage of the atomized matrix.

[0091] In this embodiment, air inlet holes are provided in the first base 7a and the second base 7b, and the air inlet holes in the first base 7a and the second base 7b are connected to form an air inlet channel. A sealing structure such as a sealing ring is provided at the connection between the first base 7a and the second base 7b to prevent the air inlet channel from being connected to other space gaps, so as to improve the effectiveness of smoking.
