[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example like Figure 1-8 As shown, one embodiment of this utility model discloses a replaceable deodorant device, comprising: The housing assembly 1 has a receiving cavity 111 and an opening 112 communicating with the receiving cavity 111; The inner box 2 is detachably disposed within the outer casing assembly 1 and adjacent to the opening 112; The top cover 3 is detachably mounted on the inner box 2; The lifting platform 4 is movably disposed in the receiving cavity 111 within the outer shell assembly 1 and is located below the inner box 2; The drive mechanism 5 is located at the bottom of the housing assembly 1 and is used to drive the lifting platform 4 to move up and down along the axial direction of the housing assembly 1. Replacement device 6, which is housed between inner box 2 and lifting platform 4, with its bottom supported by lifting platform 4.

[0020] like Figure 1-8 As shown, in some embodiments, the housing assembly 1 includes an outer cover 11 and a lower cover assembly 12 rotatable relative to it, the receiving cavity 111 is disposed inside the outer cover 11, and the opening 112 is disposed on the top of the outer cover 11; A button 113 is provided on the side wall of the outer cover 11, and a buckle 114 corresponding to the position of the button 113 is provided on the inner wall of the receiving cavity 111.

[0021] The outer cover 11 serves as the main frame, forming the main receiving cavity 111 and the top opening 112. The button 113 and the latch 114 provide trigger points for the engagement and release of the internal structure.

[0022] By dividing the outer shell assembly 1 into two relatively rotatable parts, a structural basis is provided for realizing the rotational movement of the drive mechanism 5. The cooperation between the button 113 and the latch 114 provides users with an intuitive and convenient operation method, preparing for the subsequent removal of the inner box 2 for replacement, thus improving the operability of the product and the user experience.

[0023] like Figure 1-8As shown, in some embodiments, the side wall of the inner box 2 is provided with a spring buckle 21 that engages with the buckle position 114, and the inside of the opening 112 is also provided with a spring buckle clearance position 115 located above the buckle position 114.

[0024] The engagement between the spring clip 21 and the latch 114 secures the inner box 2 within the outer cover 11. When the button 113 is pressed, the button 113 presses the spring clip 21 inward, causing it to deform and disengage from the latch 114. The spring clip clearance position 115 provides the necessary space for the spring clip 21 to move when it is deformed under pressure and when the inner box 2 is removed, preventing structural interference. At the same time, it guides the spring clip 21 when the inner box 2 is assembled into the outer cover 11.

[0025] The snap-fit ​​mechanism between the spring clip 21 and the latch 114 is stable and reliable, ensuring that the inner box 2 will not loosen during normal use. Combined with the operation of the button 113, it realizes the convenient function of "one-click unlocking", making the process of taking out the inner box 2 simple and smooth. The design of the spring clip clearance 115 ensures the smooth movement of the mechanism.

[0026] like Figure 1-8 As shown, in some embodiments, the outer side wall of the inner box 2 is provided with a raised ring 22, and the bottom of the raised ring 22 is engaged with the edge of the opening 112 at the top of the outer cover 11. The inner box 2 is provided with a first locking protrusion 23 on the outer side wall above the protruding ring 22, and the inner wall of the upper cover 3 is provided with a second locking protrusion 31. When the upper cover 3 is fitted onto the inner box 2, the second locking protrusion 31 abuts against and passes over the first locking protrusion 23, thereby achieving the locking connection between the upper cover 3 and the inner box 2.

[0027] The protruding ring 22 serves as an axial positioning component for the inner box 2. Its bottom engages with the edge of the opening 112 of the outer cover 11, limiting the inner box 2 from sinking excessively into the outer cover 11. The first locking protrusion 23 and the second locking protrusion 31 form a locking pair, which overcome and lock through elastic deformation, thus achieving a tight fixation between the upper cover 3 and the inner box 2.

[0028] The design of the protruding ring 22 ensures that the inner box 2 is installed in the outer cover 11 in a unique and accurate position, thus guaranteeing the stability of the overall structure. The upper cover 3 and the inner box 2 are connected firmly through the first locking protrusion 23 and the second locking protrusion 31, making it less likely to fall off accidentally. At the same time, the opening force is moderate, providing a good user experience. This double fixing structure ensures that the internal components will not loosen or make abnormal noise when the product is carried or moved.

[0029] like Figure 1-8 As shown, in some embodiments, the lower cover assembly 12 includes a bottom cover 121 and a lower cover 122 fixed to the bottom cover 121; The bottom cover 121 is provided with an annular buckle 123 at its top. The annular buckle 123 is movably engaged with the opening 116 provided at the bottom of the outer cover 11, so that the lower cover assembly 12 can rotate relative to the outer cover 11.

[0030] The bottom cover 121 and the lower cover 122 are fixed together to form the lower cover assembly 12. They are also provided with anti-rotation structures (such as bosses and recesses) between them. The annular buckle 123 forms an axially limited but circumferentially rotatable movable connection with the opening 116 at the bottom of the outer cover 11, which is a "live buckle" structure.

[0031] The engagement of the ring buckle 123 with the opening 116 is the core of enabling the lower cover assembly 12 to rotate relative to the outer cover 11. This structure ensures the integrity of the connection between the upper and lower shells, preventing separation, and precisely limits the rotational motion to the circumferential rotation required by the drive mechanism 5, providing a reliable motion input for the lifting function.

[0032] like Figure 1-8 As shown, in some embodiments, a drive cylinder 124 is fixedly disposed inside the lower cover 122, and the top end of the drive cylinder 124 extends into the receiving cavity 111 and is provided with an anti-rotation notch 125.

[0033] The drive cylinder 124 is fixed inside the lower cover 122 and rotates synchronously with the lower cover 122. The anti-rotation notch 125 at its top is a key feature used to cooperate with subsequent components. The design of the anti-rotation notch 125 provides anti-rotation constraint for the fixed kit 53 in the drive mechanism 5, ensuring that the rotational motion can be converted into linear motion in a preset manner, which is the basis for the stable operation of the drive mechanism 5.

[0034] like Figure 1-8 As shown, in some embodiments, the drive mechanism 5 includes: The screw 51 has its top end fixedly connected to the bottom of the lifting platform 4, and its bottom end extends into the drive cylinder 124 and is provided with a limit buckle 52. The fixing kit 53 is threadedly connected to the screw 51. The fixing kit 53 is also provided with an annular groove 54 that is fixedly connected to the top of the drive cylinder 124. The annular groove 54 is provided with an anti-rotation rib 55 that engages with the anti-rotation notch 125.

[0035] The fixing kit 53 is sleeved on the top of the drive cylinder 124 through its annular groove 54, and is locked to the anti-rotation notch 125 by the anti-rotation rib 55, so that it cannot rotate on its own, but can rotate synchronously with the drive cylinder 124. Since the screw 51 is restricted from rotating by the lifting platform 4 and the height limiting column 41, when the fixed fixing kit 53 rotates, the screw 51 is forced to make only a straight up and down movement through the threaded engagement, thereby driving the lifting platform 4 to rise and fall.

[0036] The rotational motion of the lower cover 122 is converted into the linear lifting motion of the lifting platform 4, which realizes the precise pushing of the perfume. The limit buckle 52 prevents the screw 51 from rising excessively, and the anti-rotation rib 55 and the anti-rotation notch 125 prevent the fixing kit 53 from slipping. The entire transmission process is efficient, stable and reliable. The user can rotate the lower cover 122 smoothly and there is no jamming during the lifting process.

[0037] like Figure 1-8 As shown, in some embodiments, the bottom of the outer cover 11 is symmetrically provided with at least two locking grooves 117, and the top of the bottom cover 121 is correspondingly provided with a locking protrusion 126; When the locking protrusion 126 engages with the locking groove 117, the lower cover assembly 12 and the outer cover 11 are aligned.

[0038] The locking protrusion 126 and the locking groove 117 will engage with each other at a specific position (usually the starting or alignment position), producing a distinct "click" feel, providing clear tactile and audible feedback, allowing the user to clearly perceive that the lower cover 122 has been rotated into place and is in a neat "aligned state". This not only enhances the product's refinement and operational quality, but also allows for positioning of the adjusted screw 51 height.

[0039] like Figure 1-8 As shown, in some embodiments, at least one height limiting column 41 is provided at the bottom of the lifting platform 4, and a plurality of vertical ribs 118 are circumferentially spaced on the inner wall of the receiving cavity 111. The vertical ribs 118 slide in cooperation with the height limiting column 41 to restrict the circumferential rotation of the lifting platform 4.

[0040] The vertical rib 118 serves as a fixed guide rail and forms a sliding fit with the height limiting column 41 at the bottom of the lifting platform 4. The height limiting column 41 can only slide up and down in the gap between the vertical ribs 118, thus completely restricting the circumferential rotational freedom of the lifting platform 4. This ensures that the lifting platform 4 can only perform pure axial lifting. At the same time, the fit between the height limiting column 41 and the vertical rib 118 also plays a role in guiding and stabilizing the lifting process.

[0041] like Figure 1-8 As shown, in some embodiments, the top of the lifting platform 4 is provided with a groove 42, and the bottom of the replacement device 6 is provided with a corresponding bottom support protrusion 61, which is engaged in the groove 42 for positioning.

[0042] The groove 42 and the bottom protrusion 61 are matched to achieve precise positioning and connection between the two, which can effectively prevent the replacement device 6 from sliding or deviating on the lifting platform 4, and ensure that the lifting force is directly and accurately applied to the bottom center of the replacement device 6. This makes the lifting action more stable and reliable, avoids the problem of the perfume tilting or jamming caused by uneven force, and also facilitates the quick alignment of the replacement device 6 during installation.

[0043] The replacement device 6 mainly includes a box, a base, and a breakable connection point connecting the two.

[0044] Box body: It is a container with one end open 112, and is filled with deodorant (or cream cosmetic). Base support (for mounting base protrusion 61): Set inside the box body, slidingly engaged with the inner wall of the box body, its function is to push the paste smoothly out towards the box body opening 112 under the push of the lifting platform 4; Breakable connection points: During the manufacturing process, the base and the box are connected in one piece by several (e.g., four) tiny connection points. These connection points are strong enough to maintain the initial position of the base during transportation and handling, but can be broken by a deliberately applied thrust during first use.

[0045] Initial state and installation: When the new replacement device 6 is installed in the body fragrance device, its base is located at the bottom of the box. There is a base protrusion 61 at the center of the bottom of the base. The base protrusion 61 is engaged with the groove 42 on the top of the lifting platform 4 to achieve precise positioning.

[0046] First use and break point separation: When the user rotates the lower cover 122 for the first time, driving the lifting platform 4 to rise, the lifting platform 4 applies an upward thrust to the bottom support through the cooperation of the groove 42 and the bottom support protrusion 61. When the thrust is greater than the strength of the breakable connection point, the connection point is broken instantly, making a slight breaking sound, indicating that the replacement device 6 is "activated". After that, the bottom support is separated from the box and can be raised and lowered freely under the drive of the lifting platform 4.

[0047] The ejection and retraction of the ointment: Push out: The user continues to rotate the lower cover 122 clockwise, and the lifting platform 4 pushes the separated base upward, thereby pushing the cream in the box out from the opening 112 for easy access by the user.

[0048] Retraction: When the product is not in use for a while, the user can rotate the lower cover 122 counterclockwise to lower the lifting platform 4 and the base together, retracting the cream into the box to keep the cream clean and prevent evaporation.

[0049] Replacement: When the cream is exhausted, the user can press button 113 to remove the inner box 2, take out the empty replacement device 6 from the inner box 2, and replace it with a new replacement device 6.

[0050] Replacement device 6 is made of biodegradable materials, such as (but not limited to) polylactic acid (PLA), starch-based plastics, or pulp molding materials; by adding appropriate amounts of oil-repellent and water-repellent agents to the materials, the box and base can have the required leak-proof performance.

[0051] In summary, by setting a detachable inner box 2, the deodorant device and the replacement device 6 can be used together. The user can press the button 113 to release the snap 21 from the buckle 114 and remove the inner box 2 to replace the replacement device 6, thus realizing the reuse of the deodorant device. By rotating the lower cover assembly 12, the drive cylinder 124 is rotated, which causes the fixing kit 53 to drive the screw 51 and the lifting platform 4 to move up and down along the vertical rib 118. The groove 42 on the top of the lifting platform 4 cooperates with the bottom support protrusion 61 at the bottom of the replacement device 6 to smoothly lift or retract the deodorant. The operation is convenient and reliable. At the same time, the replacement device 6 is made of biodegradable material. The replacement is disposable after use, which greatly reduces packaging waste and combines environmental protection and practicality.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
