Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] It should also be noted that, unless otherwise explicitly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Most current chargers use wired charging, and the cable harnesses are inconvenient to store, making them difficult to carry, especially outdoors. This fails to meet people's need for convenient charging anytime, anywhere. Additionally, while some chargers offer wireless charging, their operation is cumbersome and also doesn't satisfy most people's needs.

[0030] In view of this, in order to solve the above-mentioned technical problems, this application provides a charging structure 10, please refer to... Figure 1 , Figure 2 As shown, it includes an outer cover 101 and a base plate 107, which are fastened together. In this application, the charging structure 10 can be applied to an atomizing device, so the base plate 107 is integrally formed with the concave shell 20 of the atomizing device.

[0031] The outer cover 101 is rotatably mounted relative to the base plate 107. After being fastened together, the outer cover 101 and the base plate 107 form a receiving cavity 102. A circuit board 11 is disposed in the receiving cavity 102. A wireless charging coil 12 is connected to the circuit board 11. A charging position is formed on the outer cover 101. When the outer cover 101 is rotated relative to the base plate 107 to the charging position, the wireless charging coil 12 is connected to an external device through the circuit board 11 to charge the external device.

[0032] The outer cover 101 is fastened to the base plate 107. Rotating the outer cover 101 can drive the outer cover 101 to rotate relative to the base plate 107. A receiving cavity 102 is formed between the outer cover 101 and the base plate 107. The receiving cavity 102 contains a circuit board 11 and a wireless charging coil 12. When the wireless charging coil 12 is energized, it generates a magnetic field to transmit electrical energy. The wireless charging coil 12 is mounted on the circuit board 11 to achieve electrical connection between the two. By connecting the circuit board 11 to external devices, the wireless charging coil 12 can wirelessly charge external devices.

[0033] This application enables wireless charging via the wireless charging coil 12, avoiding the problem of inconvenient cable management in wired charging. Wireless charging is not restricted by cables, making the charging structure easy to carry and suitable for use in places such as airports, subways, and public places where data cables are unavailable.

[0034] In this application, a rotating outer cover 101 is used to achieve charging and power-off. When the outer cover 101 is rotated relative to the base plate 107 to the charging position, the electrical connection between the circuit board 11 and the external device can be established, and the external device can be charged. When the outer cover 101 is rotated relative to the base plate 107 to the non-charging position, the electrical connection between the circuit board 11 and the external device can be severed. Using the rotating outer cover 101 to achieve charging or power-off is simple to operate and enables free and convenient portable wireless charging.

[0035] In addition, the charging structure also includes a display screen. For example, the circuit board 11 and the display screen are integrated. In this application, the display screen can be a digital display screen, which can display status information. Since the circuit board 11 and the display screen are integrated, the display screen and the wireless charging coil 12 share the circuit board 11 to achieve electrical connection. The area on the integrated display screen and circuit board 11 other than the wireless charging coil 12 can be used to display status information. At this time, the outer cover 101 is made of transparent material so that the display information on the screen can be seen through the transparent outer cover 101, making it convenient for personnel to view.

[0036] Integrating the circuit board 11 and the display screen into one unit combines the functions of the circuit board 11 and the display screen into one unit, effectively saves space, facilitates the miniaturization of the product, and makes the product more compact and portable.

[0037] Specifically, the outer cover 101 and the circuit board 11 are fixedly installed, and the rotation of the outer cover 101 can synchronously drive the circuit board 11 to rotate; the back side of the circuit board 11 away from the wireless charging coil 12 is provided with a contact group 110 of positive and negative poles, and the back side of the circuit board 11 faces the base plate 107. The base plate 107 is provided with a spring group 131 that contacts the contact group 110 of positive and negative poles, and the spring group 131 is used to connect to external devices through the wire 22.

[0038] definition Figure 3 The side of the circuit board 11 where the wireless charging coil 12 is located is the front side. Figure 5 A contact group 110 is provided on the back side of the circuit board 11, with one positive and one negative contact. Correspondingly, a spring contact group 131 is provided on the base plate 107, with two spring contacts corresponding to the positive and negative contacts respectively. The back side of the circuit board 11 faces the base plate 107 where the spring contact group 131 is located. Thus, when the outer cover 101 rotates to the charging position, the outer cover 101 synchronously drives the circuit board 11 to rotate, and the contact group 110 on the circuit board 11 rotates to the charging position. The contact group 110 then contacts the spring contact group 131 at the charging position, achieving electrical connection between the contact group 110 and the spring contact group 131. The spring contact group 131 can then connect to an external device via the wire 22 for charging. In this application, the external device is... Figure 7The battery cell 24. In actual use, the outer cover 101 of the charging structure, that is, the area where the wireless charging coil 12 is located, is aligned with the charging area of ​​the wireless charging device or apparatus (such as a Qi wireless charger), so that the charging coil in the wireless charging device or apparatus is coupled with the wireless charging coil 12 in the charging structure to transmit electrical energy. After the electrical energy is transmitted from the wireless charging device or apparatus to the wireless charging coil 12, the wireless charging coil 12 can further transmit the electrical energy through the wire to the external device to charge the external device, such as charging the battery cell in the atomizing device.

[0039] Correspondingly, such as Figure 6 As shown, wire 22 includes two wires, which are used to connect the two spring contacts respectively. Wire 22 can generally be soldered to the spring contacts to achieve conductivity.

[0040] In some embodiments, there are two sets of contact groups 110, which are symmetrically arranged along the center of the circuit board 11. One set of contact groups 110 contacts the spring group 131 to form a first charging position, and the other set of contact groups 110 contacts the spring group 131 to form a second charging position. For example, when the outer cover 101 rotates, the rotation angle between the first charging position and the second charging position is 180 degrees.

[0041] When the outer cover 101 rotates, it will simultaneously drive the circuit board 11 and the contact group 110 to rotate. The base plate 107 and the spring contact group 131 on the base plate 107 remain stationary. The outer cover 101 drives one of the contact groups 110 to rotate to the first charging position where it contacts and connects with the spring contact group 131. When the outer cover 101 rotates to the second charging position where the other contact group 110 contacts and connects with the spring contact group 131, the outer cover 101 needs to rotate 180 degrees between the first charging position and the second charging position. This allows charging to be achieved in both the first and second charging positions. This setting makes it convenient to switch between the two charging positions, and the non-charging position between the two charging positions can also be freely controlled to switch between them, realizing the rotational control of charging or power off.

[0042] In addition, such as Figure 3 As shown, LED beads 112 are also provided around the periphery of the circuit board 11. For example, these can be LED beads, and they are arranged circumferentially on the circuit board 11. The LED beads 112 are used to represent the charging state. When the LED beads 112 are lit, it indicates that the circuit is in a charging state; when the LED beads 112 are off, it indicates that the circuit is not in a charging state.

[0043] Reference Figure 4 The outer cover 101 is also provided with a positioning pin 105 at its center, and the circuit board 11 is provided with a corresponding positioning hole 111. The outer cover 101 and the circuit board 11 are positioned and connected by the cooperation of the positioning pin 105 and the positioning hole 111.

[0044] A positioning pin 105 is provided at the center of the inner wall of the outer cover 101 facing the circuit board 11. Correspondingly, a positioning hole 111 is provided at the center of the circuit board 11. The wireless charging coil 12 is coiled into a ring with a missing center to avoid the positioning hole 111. In this way, after the positioning pin 105 of the outer cover 101 is inserted into the positioning hole 111 of the circuit board 11, the outer cover 101 and the circuit board 11 can be positioned and connected, which makes it convenient to rotate the outer cover 101 to drive the circuit board 11 to rotate synchronously.

[0045] A first positioning structure 103 is provided on the outer cover 101, and a second positioning structure is provided on the base plate 107. The first positioning structure 103 and the second positioning structure cooperate to form a charging position. The first positioning structure 103 and the second positioning structure are correspondingly provided with the contact group 110. When the first positioning structure 103 and the second positioning structure cooperate, the contact group 110 contacts the spring group 131 to position and charge at the charging position.

[0046] In some embodiments, the first positioning structure 103 is a groove and the second positioning structure is a protrusion. The groove and the protrusion are positioned after being fitted together. This positioning position is when the contact group 110 rotates to the charging position connected with the spring group 131, so as to remind the operator that the charging position has been reached.

[0047] Correspondingly, when the circuit board 11 is provided with two sets of contact groups 110 to form two charging positions, the outer cover 101 is provided with two first positioning structures 103, and the base plate 107 is provided with two second positioning structures, so as to be positioned correspondingly in the two charging positions respectively.

[0048] In some embodiments, at least one positioning portion 104 is further provided on the inner wall of the outer cover 101. For example, four positioning portions 104 are evenly distributed around the circumference of the inner wall of the outer cover 101. Figure 5 As shown, the positioning part 104 presses against the edge of the circuit board 11 to engage the circuit board 11 in the receiving cavity 102, thereby defining the relative position of the circuit board 11 in the receiving cavity 102 and thus firmly placing the circuit board 11 in the receiving cavity 102.

[0049] In some embodiments, the outer cover 101 is further provided with a third positioning structure 106, and the base plate 107 is provided with a fourth positioning structure. The third positioning structure 106 and the fourth positioning structure are matched so that the outer cover 101 and the base plate 107 are fastened together.

[0050] In this application, there are four third positioning structures 106 and four fourth positioning structures, which are evenly distributed on the outer walls of the outer cover 101 and the base plate 107. By rotating the outer cover 101 to the position where the third positioning structure 106 and the fourth positioning structure cooperate, the outer cover 101 and the base plate 107 can be fastened together to realize the connection between the two.

[0051] Based on this, refer to Figure 1 , Figure 7 As shown in the embodiment of this application, an atomizing device is also disclosed, including the charging structure 10 described above, as well as a main control board 23 and a wire 22. The wire 22 is connected to the main control board 23, and the main control board 23 is also provided with a charging interface 21. The atomizing device also includes a battery cell 24. The charging structure 10 and the wire 22 are connected, and the main control board 23 controls the charging of the battery cell 24, or directly charges the battery cell 24 through the charging interface 21.

[0052] When charging the atomizing device, one end of the wire 22 is connected to the spring group 131 of the charging structure 10. The spring group 131 and the contact group 110 are connected to conduct electricity for charging. The other end of the wire 22 is connected to the main control board 23. The main control board 23 then transmits the current to the battery cell 24, or directly connects to the electrical components through the charging interface 21 to charge the battery cell 24, thus realizing the charging function of the atomizing device.

[0053] Specifically, refer to Figure 7 The atomizing device also includes an oil-retaining cotton 25, which stores the atomizing liquid through physical adsorption. A heating element is installed within the oil-retaining cotton 25. The charging structure 10 is connected via a wire 22 and controlled by a main control board 23 to charge the battery cell 24, or it can be connected to the battery cell 24 via a charging interface 21. The battery cell 24 supplies power to the heating element within the oil-retaining cotton 25 under the control of the main control board 23. The atomizing liquid within the oil-retaining cotton 25 is guided to the heating element, which heats the liquid to produce mist that is absorbed by the user. The oil-retaining cotton 25 ensures that the atomizing liquid is evenly supplied to the heating element, preventing leakage and thus improving user comfort and taste.

[0054] In this application, the base plate 107 of the charging structure 10 is integrally set with the concave shell 20 of the atomizing device, the outer cover 101 is directly fastened inside the concave shell 20 and rotates relative to the concave shell 20, the second positioning structure and the fourth positioning structure on the base plate 107 are both located on the concave shell 20, and the spring sheet group 131 is also fixed to the concave shell 20 accordingly.

[0055] In addition, the charging structure 10 of this application can also be applied to other charging scenarios to achieve free and convenient portable wireless charging.

[0056] This atomizing device has the same structure and beneficial effects as the charging structure 10 in the foregoing embodiments. The structure and beneficial effects of the charging structure 10 have been described in detail in the foregoing embodiments and will not be repeated here.

[0057] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
