Description

Technical Field

[0001] This invention relates to the field of cosmetic box technology, and in particular to a powder box with a replaceable powder tray. Background Technology

[0002] In the cosmetics industry, powder compacts are used to hold powder materials (pressed powder) for facial beautification and are common cosmetic products. To enable the replacement of powder compacts, the applicant filed a Chinese patent application (application number 202321222085.9) disclosing a replaceable powder compact, including a box body, a lid rotatably connected to one side of the box body, and an inner compartment within the box body's interior. When the lid is closed, the inner compartment is sealed within the box body's interior. The center of the inner compartment is located within the receiving cavity, and the edge of the inner compartment has a recessed operating groove communicating with the receiving cavity. A replaceable tray is detachably mounted within the receiving cavity. Because the replaceable tray is installed from top to bottom within the receiving cavity and lacks an upward upper limit for the replaceable tray, it easily detaches from the receiving cavity, resulting in poor stability. Adding an upward upper limit or locking structure to the inner compartment would complicate the powder compact's structure and make the disassembly and replacement of the replaceable tray inconvenient. Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a replaceable toner cartridge.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A replaceable toner cartridge includes a base box, an inner compartment rotatably connected to one side of the base box and accommodating within the inner cavity of the base box, a cover that closes to the base box and encapsulates the inner compartment within the base box, and a toner cartridge detachably mounted within the inner compartment. The top surface of the inner compartment has a viewing hole, and the center of the inner compartment has a mounting cavity communicating with the viewing hole. The front side of the mounting cavity has a front opening, and the bottom wall of the mounting cavity has a clearance hole. A flexible rocker arm extends from the side wall of the clearance hole, and a locking protrusion is provided on the top surface of the flexible rocker arm. An elastic element is provided on the rear side of the mounting cavity, which applies a spring force to push the toner cartridge out of the mounting cavity. The bottom surface of the toner cartridge has a recessed guide groove and a path hole. The inlet and outlet guide groove extends from one side of the powder tray to the other side. The bottom surface of the powder tray is provided with a path guide block located in the path hole. The outer peripheral wall of the path guide block and the inner side wall of the path hole form an loading groove and a disassembly groove. One end of the loading groove is connected to one end of the disassembly groove and forms a locking position. The other end of the loading groove and the other end of the disassembly groove converge and are connected to the inner end of the inlet and outlet guide groove. The locking protrusion can enter the loading groove along the inlet and outlet guide groove, the locking protrusion can enter the locking position along the loading groove, the locking protrusion can enter the disassembly groove from the locking position, and the locking protrusion can enter the inlet and outlet guide groove along the disassembly groove. When the locking protrusion is engaged with the locking position, the elastic element is in a compressed state, and the storage cavity of the powder tray is exposed in the exposure hole.

[0006] Furthermore, the path guide block has a recess on the side away from the inlet and outlet guide groove, which serves as a locking mechanism.

[0007] Furthermore, a check guide block is provided on the inner wall of the path hole away from the inlet and outlet guide groove, and the check guide block is set opposite to the locking position; when the locking protrusion disengages from the locking position, the check guide block guides the locking protrusion to the disassembly groove.

[0008] Furthermore, the outer ends of the guide channels are provided with flared openings.

[0009] Furthermore, there are two sets of elastic elements, which are symmetrically arranged on the rear side of the mounting cavity.

[0010] Furthermore, the rear side of the mounting cavity has a rear opening, and the elastic element is an ejector spring, which is bent into the mounting cavity from one side of the rear opening.

[0011] Furthermore, a first guide surface is provided on each of the two opposite sidewalls of the mounting cavity, and a second guide surface is provided on each of the two sides of the powder tray, with a first guide surface and a second guide surface slidingly abutting each other.

[0012] Furthermore, a lifting groove is recessed on the other side of the bottom box; when the cover closes the bottom box, the front top plate of the inner compartment and the edge of the cover are positioned above the lifting groove from the inside to the outside.

[0013] Furthermore, the bottom surface of the powder tray is recessed with a push-pull groove, which is located on the side of the path hole away from the inlet and outlet guide groove.

[0014] Furthermore, one side of the cover is rotatably connected to one side of the bottom box, and the inner compartment is rotatably positioned between the cover and the bottom box, with the rotation axis of the cover and the rotation axis of the inner compartment coinciding.

[0015] The beneficial effects of this invention are as follows: In practical applications, when the powder tray is installed in the mounting cavity of the inner compartment, the powder tray compresses the elastic element, causing the elastic element to undergo restorable elastic deformation. The locking protrusion is located at the locking position and engages with the locking position. The elastic element applies an outward pushing force to the powder tray, making the locking protrusion and the locking position firmly engaged. This ensures that the powder tray is securely installed in the mounting cavity of the inner compartment, and the powder compact loaded in the powder tray's storage cavity is just exposed in the exposure hole. Simply open the face cover to apply the powder compact with a powder puff. Furthermore, the powder puff can be stored in the exposure hole. When the powder tray needs to be replaced, first rotate the inner compartment out of the inner cavity of the base box, then apply inward pressure to the outer side of the powder tray. This causes the powder tray to move inward along the mounting cavity and squeeze the elastic element. During this process, the locking protrusion disengages from its locking position and enters the disassembly groove. When the pressure is released, the elastic element will elastically recover, and the rebound force of the elastic element will push the powder tray outward. As the powder tray moves outward, the locking protrusion enters the inlet / outlet guide groove along the disassembly groove, thereby realizing the outward ejection of the powder tray for easy replacement. When a new powder tray needs to be installed, align the powder tray with the mounting cavity and the guide groove of the powder tray with the locking protrusion. Then push the powder tray into the mounting cavity, causing the locking protrusion to move along the guide groove to the insertion slot, and then from the insertion slot to the locking position. At this time, the powder tray will compress the elastic element. When the user feels the powder tray installed in place, release the inward pushing force on the powder tray. The rebound force of the elastic element will apply an outward pushing force to the powder tray, so that the locking position of the powder tray and the locking protrusion are firmly engaged, thus achieving a stable assembly of the powder tray and the inner compartment. This invention only requires pushing the powder tray into the mounting cavity of the inner compartment to achieve a stable assembly of the powder tray and the inner compartment. Simply press the powder tray to pop it out of the mounting cavity of the inner compartment. The operation is simple and easy, and the disassembly and replacement of the powder tray is convenient.

[0024] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0025] like Figures 1 to 6 As shown, the present invention provides a replaceable powder tray, comprising a base box 1, an inner compartment 2 rotatably connected to one side (rear side) of the base box 1 and capable of being accommodated within the inner cavity of the base box 1, a cover 3 that closes to the base box 1 and can encapsulate the inner compartment 2 within the base box 1, and a powder tray 4 detachably installed within the inner compartment 2. The top surface of the inner compartment 2 has a display hole 5, and the middle of the inner compartment 2 has a mounting cavity 6 communicating with the display hole 5. The front side of the mounting cavity 6 has a front opening 7. The bottom wall of the mounting cavity 6 is provided with a clearance hole 8, and an elastic swing rod 9 extends from the rear side wall of the clearance hole 8. The elastic swing rod 9 is capable of elastic recovery swinging. A locking protrusion 10 is provided on the top surface of the free end of the elastic swing rod 9. An elastic element 11 is provided on the rear side of the mounting cavity 6. The elastic element 11 is used to apply an elastic force to push the powder tray 4 out of the mounting cavity 6. The bottom surface of the powder tray 4 is recessed with an inlet / outlet guide groove 12 and a path hole. The inlet / outlet guide groove 12 extends from one side of the powder tray 4 to the other side. The outer end of the guide groove 12 penetrates the rear side of the powder tray 4. A path guide block 13 is provided on the bottom surface of the powder tray 4, located within a path hole. An insertion groove 14 and a disassembly groove 15 are formed between the outer peripheral wall of the path guide block 13 and the inner side wall of the path hole. One end of the insertion groove 14 communicates with one end of the disassembly groove 15, forming a locking position 16. The other end of the insertion groove 14 converges with the other end of the disassembly groove 15 and communicates with the inner end of the guide groove 12. The locking protrusion 10 can move along the guide groove 12. When the cam 10 enters the loading groove 14, it can enter the locking position 16 along the loading groove 14. The cam 10 can enter the disassembly groove 15 from the locking position 16. The cam 10 can enter the inlet / outlet guide groove 12 along the disassembly groove 15. When the cam 10 is engaged with the locking position 16, the elastic element 11 is in a compressed state, and the storage cavity of the powder tray 4 is exposed in the exposure hole 5. Specifically, the cam 10 is located near the front opening 7, the cam 10 extends into the mounting cavity 6, and the elastic swing rod 9 is located in the clearance hole 8.

[0026] In practical applications, when the powder tray 4 is installed in the mounting cavity 6 of the inner compartment 2, the powder tray 4 presses against the elastic element 11, causing the elastic element 11 to undergo a recoverable elastic deformation. The locking protrusion 10 is located at and engages with the locking position 16. The elastic element 11 applies an outward pushing force to the powder tray 4, making the locking protrusion 10 and the locking position 16 firmly engaged. This ensures that the powder tray 4 is securely installed in the mounting cavity 6 of the inner compartment 2, and the powder compact loaded in the storage cavity of the powder tray 4 is just exposed in the exposure hole 5. Simply open the face cover 3 to apply the powder compact with a powder puff. In addition, the powder puff can be stored / placed in the exposure hole 5. When the powder tray 4 needs to be replaced, first rotate the inner compartment 2 out of the inner cavity of the bottom box 1, and then apply inward pressing pressure to the outer side of the powder tray 4, so that the powder tray 4 moves inward along the mounting cavity 6 and squeezes the elastic element 11. During this process, the locking protrusion 10 disengages from the locking position 16 and enters the disassembly groove 15. When the pressing pressure is released, the elastic element 11 will elastically recover, and the rebound force of the elastic element 11 will push the powder tray 4 outward. As the powder tray 4 moves outward, the locking protrusion 10 enters the inlet and outlet guide groove 12 along the disassembly groove 15, thereby realizing the outward ejection of the powder tray 4, so as to facilitate the replacement of the powder tray 4. When a new powder tray 4 needs to be reinstalled, align the powder tray 4 with the mounting cavity 6, and align the inlet / outlet guide groove 12 of the powder tray 4 with the locking protrusion 10. Then push the powder tray 4 into the mounting cavity 6, causing the locking protrusion 10 to move along the inlet / outlet guide groove 12 to the insertion groove 14, and then from the insertion groove 14 to the locking position 16. At this time, the powder tray 4 will squeeze the elastic element 11. When the user feels the powder tray 4 installed in place, release the inward pushing force on the powder tray 4. The rebound force of the elastic element 11 will apply an outward pushing force to the powder tray 4, so that the locking position 16 of the powder tray 4 and the locking protrusion 10 are firmly locked together, thereby achieving a stable assembly of the powder tray 4 and the inner compartment 2. The structure of this invention is simple and low in cost. Simply pushing the powder tray 4 into the mounting cavity 6 of the inner compartment 2 is enough to achieve a stable assembly of the powder tray 4 and the inner compartment 2. Simply pressing the powder tray 4 will make the powder tray 4 pop out of the mounting cavity 6 of the inner compartment 2. The operation is simple and easy, and the disassembly and replacement of the powder tray 4 is convenient.

[0027] Specifically, the inner compartment 2 is made of one-piece plastic injection molding, which gives the elastic component 11 and the elastic swing rod 9 a certain degree of elasticity and toughness, which is beneficial for the powder tray 4 to be inserted into the inner compartment 2 and ejected from the inner compartment 2.

[0028] In this embodiment, the path guide block 13 has a recess on the side away from the inlet / outlet guide groove 12, which is a locking position 16. This structural design facilitates the forming of the locking position 16.

[0029] In this embodiment, a check guide block 17 is protruding from the inner wall of the path hole away from the inlet / outlet guide groove 12. The check guide block 17 is disposed opposite to the locking position 16. When the locking protrusion 10 disengages from the locking position 16, the check guide block 17 guides the locking protrusion 10 to the disassembly groove 15. The check guide block 17 can also guide the locking protrusion 10 from the loading groove 14 to the locking position 16. In practical applications, when the locking protrusion 10 moves to the end of the loading groove 14 and abuts against the check guide block 17, the inward pushing force on the powder tray 4 is released, and the elastic member 11 pushes the powder tray 4 outward. At this time, the check guide block 17 can guide the locking protrusion 10 to the locking position 16, so that the locking protrusion 10 and the locking position 16 are firmly locked together. When the powder tray 4 is pressed, the locking protrusion 10 will disengage from the locking position 16 and enter the disassembly groove 15 under the guidance of the check guide block 17, so that the locking protrusion 10 moves along the disassembly groove 15, thereby causing the powder tray 4 to gradually pop out of the inner compartment 2. The anti-return guide block 17 not only ensures that the locking protrusion 10 can be smoothly moved from the loading groove 14 into the locking position 16, but also ensures that the locking protrusion 10 can be smoothly moved from the locking position 16 into the disassembly groove 15.

[0030] In this embodiment, a flared opening 18 is provided at the outer end of the inlet / outlet guide groove 12; specifically, the flared opening 18 is trumpet-shaped. The flared opening 18 facilitates the insertion of the locking protrusion 10 into the inlet / outlet guide groove 12.

[0031] In this embodiment, there are two sets of elastic elements 11, which are symmetrically arranged on the rear side of the mounting cavity 6. The two sets of elastic elements 11 push the powder tray 4 out of the inner compartment 2, so that the powder tray 4 is subjected to uniform force, which is conducive to the stable pushing of the powder tray 4 out of the inner compartment 2.

[0032] In this embodiment, the rear side of the mounting cavity 6 has a rear opening 19, and the elastic element 11 is an ejector spring, which is bent into the mounting cavity 6 from one side of the rear opening 19. The rear opening 19 can provide sufficient elastic deformation space for the ejector spring, ensuring that the ejector spring can work normally, and also reduces the weight of the inner compartment 2, reduces the amount of material used in the inner compartment 2, and saves energy and is environmentally friendly.

[0033] Specifically, the spring sheet is V-shaped, arc-shaped, or U-shaped, and the elastic element 11 can also be replaced by a part that can undergo recoverable elastic deformation, such as a spring.

[0034] In this embodiment, each of the two opposite sidewalls of the mounting cavity 6 is provided with a first guide surface 20, and each of the two sides of the powder tray 4 is provided with a second guide surface 21. A first guide surface 20 and a second guide surface 21 slide against each other. During the process of the powder tray 4 being pushed inward into the mounting cavity 6 of the inner compartment 2 or popped outward from the mounting cavity 6 of the inner compartment 2, the first guide surface 20 and the second guide surface 21 slide against each other to ensure that the powder tray 4 can be stably installed into or popped out of the inner compartment 2, thus improving the operational stability of assembling and disassembling the powder tray 4.

[0035] In this embodiment, a lifting groove 22 is recessed on the other side (front side) of the bottom box 1; when the cover 3 closes the bottom box 1, the front top plate of the inner compartment 2 and the edge of the cover 3 are located above the lifting groove 22 from the inside to the outside. The lifting groove 22 provides space for the user's fingers to lift the cover, which not only makes it easy for the user to lift the cover 3, but also makes it easy for the user to lift the inner compartment 2.

[0036] In this embodiment, the bottom surface of the powder tray 4 is recessed with a push-pull groove 23. The push-pull groove 23 is located on the side of the path hole away from the inlet / outlet guide groove 12, that is, the push-pull groove 23 is located on the front side of the bottom surface of the powder tray 4. The setting of the push-pull groove 23 makes it easier for users to push and pull the powder tray 4, and also reduces the weight of the powder tray 4, reduces the amount of material used in the powder tray 4, and saves energy and is environmentally friendly.

[0037] In this embodiment, one side of the cover 3 is rotatably connected to one side of the bottom box 1, and the inner compartment 2 is rotatably disposed between the cover 3 and the bottom box 1. The rotation axis of the cover 3 and the bottom box 1 coincides with the rotation axis of the inner compartment 2 and the bottom box 1. The cover 3, the inner compartment 2, and the bottom box 1 are rotatably connected via the same pivot.

[0038] Specifically, when the cover 3 and the bottom box 1 are closed, the cover 3 and the bottom box 1 are magnetically attracted together by magnets, or the cover 3 and the bottom box 1 are fastened together by a fastening assembly. This structural design makes the cover 3 and the bottom box 1 securely closed, not easy to open accidentally, and also makes it easy for the user to open the cover 3.

[0039] Specifically, a mirror is provided on the inner wall of the face cover 3. The mirror allows the user to see themselves and makes it convenient for them to apply makeup.

[0040] It should be noted that during the relative movement of the card protrusion 10 along the inlet / outlet guide groove 12, the loading groove 14 and the disassembly groove 15, the elastic swing rod 9 can make adaptive swings to ensure that the present invention can work normally.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
