Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette charging technology, and in particular to a charging base structure. Background Technology

[0002] In the current e-cigarette industry, all devices have built-in batteries and use electronic solutions to heat tobacco or e-liquid. Since e-cigarettes are currently small and mostly portable products, their own battery capacity is small, requiring frequent external charging to extend their battery life. The traditional charging method for e-cigarettes is to directly plug the charging cable into the device to power it on. Frequent plugging and unplugging of the charging cable will reduce the product's lifespan, and there will be some resistance during the plugging and unplugging process, resulting in a poor user experience in actual operation. Utility Model Content

[0003] The main purpose of this utility model is to propose a charging base structure that aims to solve the problems of traditional electronic cigarette charging methods, which involve directly inserting the charging cable into the device to power it on. Frequent plugging and unplugging of the charging cable will reduce the product's lifespan, and there will be some resistance during the plugging and unplugging charging process, resulting in a poor user experience in actual operation.

[0004] To achieve the above objectives, the charging dock structure proposed in this utility model includes:

[0007] An electrical connection portion has opposing connection ends and contact ends, the connection ends extending into the mounting cavity and electrically connected to the circuit board structure, the contact ends extending to a location corresponding to the clearance hole, and the electrical connection portion being at least partially capable of elastically deforming upward along the axial direction of the clearance hole;

[0008] The charging dock structure has an unloaded state and a loaded state. In the unloaded state, at least part of the contact end protrudes outward from the clearance hole. In the loaded state, when the product to be charged comes into contact with the connection surface, at least part of the contact end moves inward to elastically abut against the electrical connection terminal provided on the product to be charged for electrical connection.

[0020] In the current e-cigarette industry, all devices have built-in batteries and use electronic solutions to heat tobacco or e-liquid. Since e-cigarettes are currently small and mostly portable products, their own battery capacity is small, requiring frequent external charging to extend their battery life. The traditional charging method for e-cigarettes is to directly plug the charging cable into the device to power it on. Frequent plugging and unplugging of the charging cable will reduce the product's lifespan, and there will be some resistance during the plugging and unplugging process, resulting in a poor user experience in actual operation.

[0021] This utility model proposes a charging dock structure 100 to solve the above problems.

[0022] Please see Figures 1 to 4In one embodiment of this utility model, the charging base structure 100 is mainly designed for electronic cigarettes. Traditional electronic cigarettes are typically charged via a plug-in connection similar to USB-C. This charging method presents challenges during insertion and removal, hindering quick access and resulting in a poor user experience. Furthermore, frequent plugging and unplugging reduces the lifespan of the charging structure. Considering these issues, this embodiment proposes a charging base structure 100 to change the charging method of electronic cigarettes to a contact-based method. Specifically, the charging base structure 100 is applied to electronic cigarette structures with external leakage connection terminals. The charging base structure 100 includes a base 1, within which a circuit board structure 2 is installed. One end of the circuit board structure 2 has a plug-in portion 5, which is electrically connected to the circuit board structure 2. In use, the plug-in portion 5 connects to an external charging structure to supply power to the circuit board structure 2. The plug-in portion 5 can be configured as a corresponding connector structure, including Type-C or USB-C, etc. A clearance hole 114 is provided on the connecting surface of the base, through which the mounting cavity can be connected. The connecting end of the electrical connection part is mounted on the circuit board structure 2, forming an electrical connection between the two. The contact end of the electrical connection part extends to the location of the clearance hole 114 and can elastically deform along the axial direction of the clearance hole 114. The deformation state of the contact end depends on whether the electronic cigarette structure is placed on the connecting surface for charging. Specifically, in the unloaded state, no related structure is in contact with the connecting surface. At this time, the contact end is at least partially protruding outward from the clearance hole 114. In the loaded state, the charging end of the electronic cigarette abuts against the connecting surface, and the contact end moves at least partially inward to elastically abut against the electrical connection terminal provided on the product to be charged, forming an electrical connection state. At this time, the electronic cigarette can be charged by contact. Using this contact-based charging method, the e-cigarette, during charging, can make contact and conduction with the two contact ends through its own gravity. After sufficient contact, the outer end of the e-cigarette contacts the connecting surface, which supports the e-cigarette structure. In this state, the connecting terminals on the e-cigarette and the contact ends maintain a relatively stable contact, thus ensuring stable charging. Therefore, there is no insertion or removal resistance during charging, enabling quick insertion and removal of the e-cigarette structure during charging, further improving the user experience. It is conceivable that the traditional plug-in charging structure could still be retained on the charging end of the e-cigarette structure, without affecting the aforementioned contact-based charging structure. Furthermore, retaining the traditional plug-in charging structure provides another charging option for e-cigarettes.

[0023] Specifically, the electrical connection part is configured as a connecting spring 3, which is made of a metal material with good conductivity, such as beryllium copper. Specifically, the clearance hole 114 and the electrical connection part are configured as a one-to-one structural group, with two structural groups. Each of the connecting spring 3 and the clearance hole 114 corresponds to one of the two connection terminals of the electronic cigarette. The connecting spring 3 is bent in its extending direction to form a protrusion 31. The contact end includes the protrusion 31. During actual installation, the protrusion 31 is disposed within the clearance hole 114, with its end protruding from the connection surface. Therefore, when the charging terminal of the electronic cigarette is placed on the connection surface, the two protrusions 31 can respectively contact the two connection terminals on the electronic cigarette for charging.

[0024] If the charging end of the electronic cigarette structure is not planar, it will be difficult to maintain a stable charging state on the connection surface. To enable electronic cigarettes of various shapes to be charged on the connection surface, a receiving groove 113 is provided at the upper end of the base 1. The receiving groove 113 is used to accommodate the product to be charged. The specific shape of the receiving groove 113 can be set according to the actual shape of the corresponding electronic cigarette charging end, and is not limited here. In this case, the connection surface is contained within the inner bottom wall of the receiving groove 113. During actual charging, placing the charging end of the electronic cigarette in the receiving groove 113 allows a conductive state to be formed between the electronic cigarette's connection terminal and the electrical connection spring 3. The receiving groove 113 has a certain depth, ensuring the stability of the electronic cigarette structure's position after the electronic cigarette is placed inside, thereby ensuring a stable charging process.

[0025] To facilitate the installation of internal structures such as circuit boards, the base 1 is designed as a split structure. Specifically, the base 1 includes an upper shell 11 and a lower shell 12, with the mounting cavity defined between the upper shell 11 and the lower shell 12. A receiving groove 113 is formed in the upper shell 11, and multiple positioning post structures 115 are provided on the bottom outer wall of the receiving groove 113 for positioning the circuit board structure 2. The circuit board structure 2 is then fixedly installed to the bottom outer surface of the receiving groove 113 by screws. Considering that most electronic cigarettes are elongated, and their charging structure is generally located at one end along their length, when the electronic cigarette is placed inside the receiving groove 113, the center of gravity of the entire structure shifts upwards. Due to the compact structure, the entire charging structure is easily tipped over by external force after the electronic cigarette is placed in the receiving groove 113. To further improve the stability of the entire charging base structure 100 during use, a counterweight 4 is provided in the mounting cavity. The counterweight 4 increases the overall weight of the entire charging base structure 100, thereby ensuring its overall stability after being combined with the electronic cigarette structure.

[0026] To make the entire charging base structure 100 more compact, achieving a small and portable design, the mounting cavity space formed by the upper shell 11 and the lower shell 12 is limited in size. Therefore, to ensure a better counterweight effect, in this embodiment, the counterweight 4 is designed as a wraparound structure. Specifically, a clearance groove 43 is provided on the upper surface of the counterweight 4. The clearance groove 43 includes a first groove 431 and a second groove 432 that are interconnected. The first groove 431 is disposed corresponding to the outer bottom wall of the receiving groove 113, and the second groove 432 is disposed corresponding to the circuit board structure 2. Figure 3 As shown, after the upper shell 11 and the lower shell 12 are assembled into a whole, the clearance groove 43 surrounds the outer periphery of the receiving groove 113. Therefore, within the limited space inside the mounting cavity, the counterweight 4 can be set to be as large as possible, thereby ensuring the stability of the entire charging base structure 100 during use.

[0027] The upper shell 11 and the lower shell 12 are connected by a snap-fit ​​structure, thereby achieving quick disassembly. Specifically, the lower shell 12 has an annular protrusion 122 on its end face facing the upper shell 11, and a plurality of snap-fit ​​protrusions 1221 on the annular protrusion 122. The upper shell 11 has a plurality of snap-fit ​​grooves 111 corresponding to the plurality of snap-fit ​​protrusions 1221. The plurality of snap-fit ​​protrusions 1221 are respectively snapped into the corresponding snap-fit ​​grooves 111. After installation, the upper shell 11 and the lower shell 12 form an integral shell structure. Meanwhile, in order to ensure that the snap-fit ​​protrusions 1221 and the snap-fit ​​grooves 111 correspond during the snap-fit ​​installation of the upper shell 11 and the lower shell 12, a guide rib 112 protruding from the inner wall of the upper shell 11 is provided. The guide rib 112 extends along the opening direction of the upper shell 11. A guide groove 1222 corresponding to the guide rib 112 is also provided on the annular protrusion 122. During actual installation, the guide rib 112 slides inside the guide groove 1222, thereby allowing multiple snap-fit ​​protrusions 1221 and multiple snap-fit ​​grooves 111 to be snapped together, improving the convenience of the installation process.

[0028] During actual installation, the counterweight 4 is installed inside the annular protrusion 122. To ensure the weight of the counterweight 4, it is designed to be as large as possible, with its sidewalls essentially in contact with the inner wall of the annular protrusion 122. During installation, the two mounting holes 42 on the counterweight 4 are aligned with the two threaded sleeves 121 on the two lower shell portions 12. Then, screws are used to engage with the threaded sleeves 121, thereby installing the counterweight 4 onto the inner end face of the lower shell portion 12. Installing the counterweight 4 using the two threaded sleeves 121 ensures the stability of its position after installation.

[0029] During the installation of the upper shell 11 and the lower shell 12, the outer wall of the annular protrusion 122 is attached to the inner wall of the upper shell 11 to ensure a tight fit. The snap-fit ​​end of the snap-fit ​​protrusion 1221 protrudes from the outer wall of the annular protrusion 122. During the installation of the upper shell 11 and the lower shell 12, one end of the snap-fit ​​protrusion 1221 slides against the inner wall of the upper shell 11, causing partial deformation of the end of the snap-fit ​​protrusion 1221 towards the center of the lower shell 12. The counterweight 4 has multiple clearance grooves 41 corresponding to the multiple snap-fit ​​protrusions 1221. When the multiple snap-fit ​​protrusions 1221 undergo elastic deformation, their deformation position is located inside the clearance grooves 41, thus ensuring the smooth operation of the snap-fit ​​process.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
