Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application.

[0024] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0025] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning.

[0026] In existing technologies, the method of connecting the display screen 130 and the circuit board 120 using FPC cables is cumbersome and prone to assembly errors. Soldering connections are also susceptible to cold solder joints during manufacturing. Both methods can lead to poor contact between the display screen 130 and the circuit board 120, resulting in malfunction of either the display screen 130 or the circuit board 120. The connector 140 provided in this application offers a simple installation method and a straightforward electrical connection structure, ensuring a secure connection between the circuit board 120 and the display screen 130, preventing poor contact and avoiding functional failures.

[0027] Example 1

[0028] This application provides a display module 100 for an atomizing device. Please refer to [reference needed]. Figure 1-6 The display module 100 includes a housing 110, a circuit board 120, a display screen 130, and a connector 140.

[0029] Please refer to Figure 4-5 A circuit board 120 is disposed within a housing 110, and the circuit board 120 has a first electrical connection structure (not shown). A display screen 130 is disposed within or outside the housing 110. A connector 140 is disposed on and electrically connected to the display screen 130. The connector 140 has a second electrical connection structure 141, which is detachably connected to the first electrical connection structure.

[0030] In this application, a first electrical connection structure is provided on the circuit board 120, a connector 140 is provided on the display screen 130, and a second electrical connection structure 141 is provided on the connector 140. The second electrical connection structure 141 is detachably connected to the first electrical connection structure, thereby realizing the electrical connection between the display screen 130 and the circuit board 120. The connector 140 has a simple structure, is easy to install, and is directly set on the display screen 130, which can reduce operation steps and reduce costs.

[0031] like Figure 4-5 The connector 140 is provided with a holding space 142 having an installation opening 1421. The second electrical connection structure 141 is disposed in the holding space 142. The portion of the circuit board 120 provided with the first electrical connection structure is assembled into the holding space 142 from the installation opening 1421 so that the second electrical connection structure 141 is electrically connected to the first electrical connection structure, and the second electrical connection structure 141 elastically abuts against the first electrical connection structure to hold the circuit board 120 in the holding space 142.

[0032] By providing a retaining space 142 on the connector 140, and placing the second electrical connection structure 141 within the retaining space 142, and making the second electrical connection structure 141 elastically abut against the first electrical connection structure, the circuit board 120 can be retained within the retaining space 142. This not only achieves electrical connection between the circuit board 120 and the display screen 130, but also securely connects the circuit board 120 and the display screen 130, preventing poor contact between the circuit board 120 and the display screen 130.

[0033] Please refer to Figure 4 The mounting opening 1421 is located on the side of the connector 140 away from the display screen 130, and the circuit board 120 is positioned perpendicular to the display screen 130.

[0034] The mounting opening 1421 is located on the side of the connector 140 opposite to the display screen 130. After aligning with the mounting opening 1421, the circuit board 120 can be directly pushed into the retaining space 142, facilitating disassembly and installation. The circuit board 120 is positioned perpendicular to the display screen 130, which facilitates the subsequent arrangement of other structures.

[0035] Please refer to Figure 3 The circuit board 120 is provided with a clearance groove 121, and the sidewall of the clearance groove 121 is provided with a first snap-fit ​​structure 1211, such as... Figure 4 A second snap-fit ​​structure 1422 is provided on the outer side wall of the snap-fit ​​space 142. The side wall of the snap-fit ​​space 142 extends into the clearance groove 121, and the second snap-fit ​​structure 1422 cooperates with the first snap-fit ​​structure 1211 to further fix the circuit board 120 and the display screen 130.

[0036] In addition to the second electrical connection structure 141 elastically abutting against the first electrical connection structure to initially hold the circuit board 120 in the holding space 142, this application provides a first locking structure 1211 in the clearance groove and a second locking structure 1422 on the outer wall of the holding space 142. By engaging the first locking structure 1211 and the second locking structure 1422, the circuit board 120 and the connector 140 can be further fixedly connected, thereby making the connection between the circuit board 120 and the connector 140 more secure and avoiding poor contact between the circuit board 120 and the display.

[0037] Please refer to Figure 3-4 The first snap-fit ​​structure 1211 includes a snap-fit ​​groove, and the second snap-fit ​​structure 1422 includes a snap fastener, which is elastic so that the snap fastener can extend into or leave the snap-fit ​​groove.

[0038] The elastic snap-fit ​​mechanism allows the circuit board 120 and display screen 130 to be easily removed from the slot by avoiding the side wall of the slot. Conversely, when the circuit board 120 and display screen 130 need to be installed, the snap-fit, by avoiding the side wall of the slot, can easily extend into the slot.

[0039] Please refer to Figure 3 In this embodiment, two clearance grooves 121 are provided, and each clearance groove 121 is provided with a first snap-fit ​​structure 1211, and a second snap-fit ​​structure 1422 is provided in a one-to-one correspondence with the first snap-fit ​​structure 1211.

[0040] By providing two clearance grooves 121 on the circuit board 120, the circuit board 120 can be more stably fixed to the connector 140 compared to providing one clearance groove 121.

[0041] Please refer to Figure 4 Within the holding space 142, two flexible second electrical connection structures 141 are respectively provided on opposite sides. These second electrical connection structures 141 elastically abut against the first electrical connection structure to hold and fix the circuit board 120 within the holding space 142. More specifically, there are multiple second electrical connection structures 141 on any side of the holding space 142. The first electrical connection structure and the second electrical connection structure 141 are provided in a one-to-one correspondence.

[0042] By providing relatively flexible second electrical connection structures 141 within the holding space 142, the two second electrical connection structures 141 work together to clamp the circuit board 120.

[0043] More specifically, such as Figure 4 From the view shown, the upper and lower walls of the holding space 142 have inclined slopes at the mounting opening 1421, which facilitates the insertion of the circuit board 120 into the holding space 142.

[0044] Please refer to Figure 5 The display screen 130 is disposed on the outer side wall of the housing 110, and the outer side wall of the housing 110 is provided with a connection port 111 that penetrates the outer side wall of the housing 110. The connector 140 is electrically connected to the circuit board 120 through the connection port 111.

[0045] The display screen 130 is set on the outer wall of the housing 110 so that the content displayed on the display screen 130 can be seen from the outside after the atomizing device is assembled. The circuit board 120 is fixedly set inside the housing 110. The connector 140 passes through the connection port 111 and connects the circuit board 120 and the display screen 130. The display screen 130 is more securely installed by fixing the circuit board 120.

[0046] Please refer to Figure 5 The outer side wall of the housing 110 is recessed with a mounting groove 112, and the display screen 130 is disposed in the mounting groove 112.

[0047] By avoiding the mounting slot 112, the display screen 130 can be installed inside the mounting slot 112, which can save space in the entire atomizing device.

[0048] In this embodiment, an adhesive layer (not shown) is provided on the outer wall of part of the housing 110, and the adhesive layer is located between the mounting groove 112 and the display screen 130 for bonding and fixing the display screen 130. More specifically, an adhesive layer is provided in the mounting groove 112, and the adhesive layer is located between the mounting groove 112 and the display screen 130 for bonding and fixing the display screen 130.

[0049] Compared to the aforementioned connector 140, the display screen 130 has a larger overall area. The parts where connectors 140 are not installed are prone to shaking during use. Therefore, by setting an adhesive layer between the mounting slot 112 and the display screen 130, the display screen 130 is fixed to prevent it from shaking and thus affecting the subsequent display effect.

[0050] Please refer to Figure 1-3 The circuit board 120 also has a third electrical connection structure 122. The end of the third electrical connection structure 122 away from the circuit board 120 passes through the housing 110 and is used for electrical connection with the atomizer of the atomizing device. Thus, the circuit board 120 can control the working state of the atomizer, and the circuit board 120 can control the display screen 130 to display the liquid volume and working status of the atomizer. In the foregoing, the vertical arrangement of the circuit board 120 and the display screen 130 facilitates the electrical connection of the third electrical connection structure 122 to the atomizer after installation.

[0051] Please refer to Figure 6 The housing 110 is also provided with an air regulating channel 113 inside, which is used to communicate with the air regulating channel 113 of the atomizer. The bottom of the housing 110 is provided with an air regulating opening (not shown), and the air regulating opening is provided with an air regulating valve (not shown). The air regulating valve is used to adjust the size of the air regulating opening and control the amount of air entering the air regulating channel 113, thereby adjusting the amount of air entering the atomizing device.

[0053] This application provides a display module 100 for an atomizing device. Please refer to [reference needed]. Figure 1-6 The display module 100 includes a housing 110, a circuit board 120, a display screen 130, and a connector 140.

[0054] Please refer to Figure 4-5A circuit board 120 is disposed within a housing 110, and the circuit board 120 has a first electrical connection structure (not shown). A display screen 130 is disposed within or outside the housing 110. A connector 140 is disposed on and electrically connected to the display screen 130.

[0055] In this application, a first electrical connection structure is provided on the circuit board 120, a connector 140 is provided on the display screen 130, and a second electrical connection structure 141 is provided on the connector 140. The second electrical connection structure 141 is detachably connected to the first electrical connection structure, thereby realizing the electrical connection between the display screen 130 and the circuit board 120. The connector 140 has a simple structure, is easy to install, and is directly set on the display screen 130, which can reduce operation steps and reduce costs.

[0056] The connector 140 is provided with a holding space 142 having an installation opening 1421. The second electrical connection structure 141 is disposed in the holding space 142. The portion of the circuit board 120 provided with the first electrical connection structure is assembled into the holding space 142 from the installation opening 1421, so that the second electrical connection structure 141 is electrically connected to the first electrical connection structure, and the second electrical connection structure 141 elastically abuts against the first electrical connection structure to hold the circuit board 120 in the holding space 142.

[0057] like Figure 4-5 By providing a retaining space 142 on the connector 140, and placing the second electrical connection structure 141 within the retaining space 142, and making the second electrical connection structure 141 elastically abut against the first electrical connection structure, the circuit board 120 can be retained within the retaining space 142. This not only achieves electrical connection between the circuit board 120 and the display screen 130, but also securely connects the circuit board 120 and the display screen 130, preventing poor contact between the circuit board 120 and the display screen 130.

[0058] Please refer to Figure 4 The mounting opening 1421 is located on the side of the connector 140 away from the display screen 130, and the circuit board 120 is positioned perpendicular to the display screen 130.

[0059] The mounting opening 1421 is located on the side of the connector 140 opposite to the display screen 130. After aligning with the mounting opening 1421, the circuit board 120 can be directly pushed into the retaining space 142, facilitating disassembly and installation. The circuit board 120 is positioned perpendicular to the display screen 130, which facilitates the subsequent arrangement of other structures.

[0060] Please refer to Figure 3The circuit board 120 is provided with a relief groove 121, and the side wall of the relief groove 121 is provided with a first snap-fit ​​structure 1211. The outer side wall of the holding space 142 is provided with a second snap-fit ​​structure 1422. The side wall of the holding space 142 extends into the relief groove 121, and the second snap-fit ​​structure 1422 cooperates with the first snap-fit ​​structure 1211 to further fix the circuit board 120 and the display screen 130.

[0062] In this embodiment, the second snap-fit ​​structure 1422 includes a snap-fit ​​groove, and the first snap-fit ​​structure 1211 includes a snap fastener, which is elastic so that the snap fastener can extend into or leave the snap-fit ​​groove.

[0063] The elastic snap-fit ​​mechanism allows the circuit board 120 and display screen 130 to be easily removed from the slot by avoiding the side wall of the slot. Conversely, when the circuit board 120 and display screen 130 need to be installed, the snap-fit, by avoiding the side wall of the slot, can easily extend into the slot.
