Description

Technical Field

[0001] This application relates to the field of beauty device technology, and in particular to a sliding cover structure for a beauty device. Background Technology

[0002] Beauty devices are primarily used to assist users in skin care and beauty maintenance, enabling various skincare procedures such as cleansing, nutrient delivery, firming and lifting, light therapy, and massage. Users can choose appropriate beauty devices based on their skin type and specific needs, and enhance facial care effects by injecting different types of serums into the device head. In existing technology, a sliding cover is typically installed at the corresponding position of the serum inlet to seal the inlet when not in use, preventing dust from entering.

[0003] Most common sliding cover structures rely on the alignment and cooperation of elastic protrusions and grooves, or on the interlocking structure of blocks and slots to limit and fix the position of the sliding cover. These structures require significant force to switch the cover between open and closed states, making the sliding operation somewhat laborious and lacking in ease of use. Furthermore, the smoothness and feel of the sliding cover during movement are poor, affecting the overall user experience. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems and provide a sliding cover structure for a beauty device. The sliding cover operation of this application is effortless and smooth, and provides a good user experience.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A sliding cover structure for a beauty device is disclosed. The sliding cover is mounted on the body of the beauty device and includes a connector, a push cover, and a torsion spring. The push cover is fastened to the connector, and the connector has a sliding groove. The connector is slidably mounted on the body of the beauty device through the sliding groove.

The fixed end of the torsion spring is fastened to the positioning post, and the other end of the torsion spring is a movable end and fastened to the connector. When the push cover is pushed, the connector slides along the sliding groove and compresses the torsion spring. When the movable end of the torsion spring passes the positioning post in the horizontal direction, under the restoring force of the torsion spring, the sliding cover automatically slides to the other side of the sliding cover groove and achieves a limit, thereby changing the open or closed state of the installation port.

[0006] In this application, a torsion spring driven sliding cover structure is adopted. Utilizing the automatic rebound characteristic of the torsion spring after reaching the critical position, the sliding cover can quickly and stably complete the switching between open and closed states the instant it passes the positioning post. This significantly reduces the force required for user sliding operations, improves the ease and smoothness of operation, and the sliding cover is not easily displaced when no force is applied. At the same time, this structure achieves automatic limiting and state maintenance of the sliding cover through the restoring force of the torsion spring, avoiding the jamming and frictional resistance caused by the traditional protrusion and groove combination. This effectively improves the smoothness and feel of the sliding cover during movement, enhances the user experience, and increases the automation and reliability of product use. Furthermore, the entire drive and reset mechanism has a simple and compact structure, integrated within the sliding cover, eliminating the need for complex external mechanisms, ensuring aesthetics, and facilitating manufacturing.

[0007] In one embodiment, a connecting post extends from the upper surface of the connector near the center, and the movable end of the torsion spring is sleeved on the connecting post.

[0008] In one embodiment, both the positioning post and the connecting post have radially protruding limiting blocks on one side to limit the axial displacement of the torsion spring.

[0009] In one embodiment, the bottom of the positioning post is provided with a lower opening groove, and the bottom of the connecting post is provided with a side opening groove on the side corresponding to the positioning post, so as to provide elastic deformation space for the positioning post and the connecting post; the position of the limiting block of the positioning post corresponds to the position of the lower opening groove, and the position of the limiting block of the connecting post corresponds to the position of the side opening groove.

[0010] In one embodiment, in its natural state, the included angle between the fixed arm where the fixed end of the torsion spring is located and the movable arm where the movable end is located ranges from 68° to 72°. In one embodiment, the torsion spring has annular ends that are sleeved on the positioning post and the connecting post at its two ends, and a winding loop is provided in the middle of the torsion spring.

[0011] In one embodiment, the connector has a guide hole whose length direction is consistent with the sliding direction of the sliding cover, and the positioning post passes through the guide hole.

[0012] In one embodiment, the sliding cover groove is provided with a limiting guide rail below the mounting port, and the limiting guide rail is slidably installed in the sliding groove.

[0013] In one embodiment, the outer side of the push cover is provided with an anti-slip protrusion in the middle, and the two sides of the anti-slip protrusion are arc-shaped surfaces that gradually expand outward.

[0014] In one embodiment, the connector has engagement grooves on both sides of its side, and the inner sidewall of the push cover has corresponding locking blocks. The locking blocks and engagement grooves work together to achieve a fixed connection between the push cover and the connector. Attached Figure Description

Detailed Implementation

[0016] This application provides a sliding cover structure for a beauty device, addressing the technical issues of existing sliding covers being laborious to operate and lacking ease of use. Furthermore, the sliding cover's poor smoothness and feel during movement negatively impacts the overall user experience.

[0017] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Please see Figures 1 to 4This application provides a sliding cover structure for a beauty device. The sliding cover 100 is installed on the beauty device body 200. The sliding cover 100 includes a connector 110, a push cover 120, and a torsion spring 130. The push cover 120 is fastened to the connector 110. The connector 110 is provided with a sliding groove 111, and the connector 110 is slidably installed on the beauty device body 200 through the sliding groove 111. The beauty device body 200 is provided with an installation port 210 and a sliding cover 100 groove. A positioning post 221 is provided on the sliding cover 100 groove, and the positioning post 221 passes through the connector 110. 0. The fixed end 131 of the torsion spring 130 is fastened to the positioning post 221, and the other end of the torsion spring 130 is the movable end 132, which is fastened to the connector 110. When the push cover 120 is pushed, the connector 110 slides along the sliding groove 111 and compresses the torsion spring 130. When the movable end 132 of the torsion spring 130 passes the positioning post 221 in the horizontal direction, under the restoring force of the torsion spring 130, the sliding cover 100 automatically slides to the other side of the sliding cover 100 groove and achieves a limit, so as to change the open or closed state of the mounting port 210.

[0019] Specifically, the beauty device body 200 has a sliding cover groove 111 for mounting the sliding cover 100 and providing sliding space for the sliding cover 100. An installation port 210 for mounting an essence bottle is located on the upper side of the sliding groove 111. The installation port 210 has an inlet, and the essence bottle is inserted into and connected to the inlet. The sliding cover 100 consists of a connecting piece 110 and a push cover 120 that are interlocked. The cavity between the connecting piece 110 and the sliding cover 100 forms the installation and deformation space for the torsion spring 130. A guide opening on the connecting piece 110 is installed in the groove of the sliding cover 100. When the sliding cover 100 is pushed, the connecting piece 110 slides along the guide opening. A positioning post 221 located below the installation port 210 passes through the connecting piece 110. One end of the torsion spring 130 is sleeved on the positioning post 221, serving as the positioning end. The other end of the torsion spring 130 is sleeved on a connecting post on the upper surface of the connecting piece 110. The column 112 forms a movable end 132. When pushed and slid, the position of the column 112 moves accordingly, and the torsion spring 130 is gradually compressed until it crosses the horizontal line corresponding to the positioning column 221. Under the restoring force of the torsion spring 130, the sliding cover 100 is automatically moved to the other side of the sliding cover 100 groove to change the open or closed state of the mounting port 210. Utilizing the characteristic of the torsion spring 130 to generate a reverse restoring force after passing the midpoint, the maximum operating force required for the user to slide the cover 120 is reduced, making the opening and closing action more effortless and smooth, and effectively improving the operating feel. This structure can automatically drive the sliding cover 100 to quickly and accurately complete the remaining stroke and stably limit it to the target position after the movable end 132 of the torsion spring 130 crosses the dead point, realizing the automatic and reliable switching of the state of the mounting port 210. The overall structure is simple and compact, and improves the automation and reliability of product use.

[0020] Furthermore, a connecting post 112 extends from the upper surface of the connector 110 near the center, and the movable end 132 of the torsion spring 130 is sleeved on the connecting post 112. The connecting post 112 is located in the center of the upper surface of the connector 110, making the stress point of the torsion spring 130 more central, which matches the position of the positioning post 221, ensuring the balance and stability of the torque transmission of the torsion spring 130. At the same time, the sleeve connection is reliable and easy to assemble.

[0021] Furthermore, both the positioning post 221 and the connecting post 112 have radially protruding limiting blocks 1121 on one side to limit the axial displacement of the torsion spring 130. Both the positioning post 221 and the connecting post 112 are cylindrical, with a radially protruding limiting block 1121 on one side of their outer periphery. The upper end surface of the limiting block 1121 is inclined, facilitating the insertion of both ends of the torsion spring 130 into the positioning post 221 and the connecting post 112; and effectively limiting the axial displacement of the torsion spring 130, preventing it from loosening or misaligning during operation, thus improving the reliability of the structure. The positioning post 221 has a lower opening groove 2211 at its bottom, and the connecting post 112 has a side opening groove 1122 on the side corresponding to the positioning post 221 at its bottom, providing elastic deformation space for the positioning post 221 and the connecting post 112. The position of the limiting block 1121 of the positioning post 221 corresponds to the position of the lower opening groove 2211, and the position of the limiting block 1121 of the connecting post 112 corresponds to the position of the side opening groove 1122. By setting opening grooves in a specific direction at the bottom of the positioning post 221 and the connecting post 112, the opening direction corresponds to the force of the torsion spring 130, ensuring that the positioning post 221 and the connecting post 112 have sufficient rigidity in the direction of force. The lower opening groove 2211 and the side opening groove 1122 make them have radial elasticity on the corresponding side, which simplifies the assembly process of the torsion spring 130, reduces the assembly difficulty, and effectively prevents the torsion spring 130 from accidentally coming off the post.

[0022] Furthermore, in its natural state, the included angle between the fixed arm where the fixed end 131 of the torsion spring 130 is located and the movable arm where the movable end 132 is located ranges from 68° to 72°. The two ends of the torsion spring 130 are respectively formed with annular ends that fit onto the positioning post 221 and the connecting post 112. A winding loop 133 is provided in the middle of the torsion spring 130. The annular ends of the torsion spring 130 are respectively fitted onto the positioning post 221 and the connecting post 112, and a winding loop 133 is also provided at the intersection of the fixed arm and the movable arm. This ensures that the middle of the torsion spring 130 has sufficient rigidity, is not easily deformed, and facilitates the concentration of elastic force, ensuring efficient and stable torque transmission. In this embodiment, the included angle between the fixed arm and the movable arm is preferably 70.8°, optimizing the elastic restoring force and stroke relationship of the torsion spring 130 to ensure it provides just the right driving force, making the sliding cover 100 move both sensitively and stably.

[0023] For details, please refer to [link / reference]. Figures 3 to 4The connector 110 has a guide hole 113 whose length direction is consistent with the sliding direction of the sliding cover 100, and the positioning post 221 passes through the guide hole 113. The guide hole 113 is elongated and cooperates with the positioning post 221 to provide precise guidance for the sliding of the connector 110. The sliding cover 100 groove is provided with a limiting guide rail 222 below the mounting opening 210. The limiting guide rail 222 is slidably installed in the sliding groove 111. The limiting guide rail 222 is arranged in parallel and has a hook shape at the top. This not only makes installation simple, but also ensures stability during the sliding process and limits the movement trajectory by sliding the limiting guide rail 222 on both sides with the sliding groove 111, thus avoiding overtravel.

[0024] Furthermore, the outer side of the push cover 120 is provided with an anti-slip protrusion 121 in the middle, and the two sides of the anti-slip protrusion 121 are arc-shaped curved surfaces that gradually expand outwards. The anti-slip protrusion 121 in the middle of the outer side of the push cover 120 and the arc-shaped curved surfaces on both sides increase the friction and comfort when pushing with fingers and prevent slippage. The two sides of the connector 110 are provided with engagement grooves 114, and the inner sidewall of the push cover 120 is provided with corresponding locking blocks 122. The push cover 120 and the connector 110 are fixedly connected by the cooperation of the locking blocks 122 and the engagement grooves 114. The engaging grooves 114 on both sides of the connector 110 have stepped positions and are engaged and fixed with the locking block 122. The connection between the push cover 120 and the connector 110 is achieved through the cooperation of the locking block 122 and the engaging groove 114. This structure is simple and reliable, easy to assemble, and has high connection strength, ensuring that the push cover 120 and the connector 110 can maintain a stable connection under frequent operation.
