[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for the purpose of illustrating the present invention, and are not intended to limit the present invention. For the sake of simplicity, each figure only shows a schematic representation of the parts related to the present invention and does not represent the actual structure of the product. Also, for ease of understanding, some figures may show only one schematic representation of components having the same structure or function or may be marked only one. In this specification, "one" may mean not only "only one" but also "one or more." [Example]

[0014] Referring to Figures 1 to 4, this embodiment provides a technical solution of a two-stage retractable nozzle, including:

[0015] Case Assembly 1: The container includes a base 11, an upper cover 12 detachably connected to the upper end of the side wall of the base 11, and a bottom cover 13 detachably connected to the lower end of the side wall of the base 11.

[0016] Primary Payout Assembly 2: The device comprises a fork 21 fixedly connected to the inner wall of the base 11, a screw bundle 22 arranged between the fork 21 and the base 11, and a moving body 23 arranged in the inner cavity of the fork 21. The screw bundle 22 is rotatably connected to the fork 21, a guide pin on the outer wall of the moving body 23 passes through a guide groove of the fork 21, and the moving body 23 is arranged in the rotating inner groove of the screw bundle 22. By rotating the screw bundle 22 forward and backward, the moving body 23 moves up and down along the inner wall of the fork 21.

[0017] Secondary Feeding Assembly 3: The device comprises a rotating part 31 rotatably connected to the bottom of the moving body 23, a connecting rod 33 slidably connected to the outer wall of the rotating part 31, and a pushing part 32 disposed at the bottom of the inner cavity of the moving body 23. The outer wall of the connecting rod 33 is slidably connected to the bottom cover 13, and the tail of the pushing part 32 passes through the lower end surface of the moving body 23 and is threadedly connected to the inner wall of the rotating part 31. When the bottom cover 13 is rotated forward or backward, the pushing part 32 moves up and down.

[0018] In a specific implementation, the components inside the lipstick that facilitate its delivery mainly include a base 11, a fork 21 fixedly connected to the base 11, a screw bundle 22 sleeve-likely arranged around the fork 21, and a moving body 23 arranged within the fork 21. The lipstick stick is housed within the moving body 23. A guide pin is provided on the side wall of the moving body 23, and two guide grooves are provided on the side wall of the fork 21 symmetrically arranged along the vertical direction. The inner wall of the screw bundle 22 has a spiral rotating inner groove. The guide pin of the moving body 23 passes through the guide groove and is then positioned within the screw bundle 22. When the screw bundle 22 is rotated, the inner wall of the rotating inner groove applies a downward or upward force to the guide pin. Meanwhile, the guide pin of the fork 21 restricts the movement of the moving body 23. Therefore, when the screw bundle 22 is rotated, the rotating inner groove moves the moving body 23 up and down along the guide pin. Moreover, the specific connection method of the moving body 23, the fork 21 and the screw bundle 22 is a conventional technique used in lipstick manufacturing, so it will not be described in further detail.

[0019] In a specific implementation, the connection between the bottom cover 13 and the base 11 is as follows: a first sliding groove is provided on the upper part of the inner wall of the bottom cover 13, and a first sliding protrusion is provided on the outer wall of the base 11 at a position that coincides with the first sliding groove. The first sliding protrusion can slide within the first sliding groove as the base 11 rotates.

[0020] In a specific implementation, the connection between the bottom cover 13 and the connecting rod 33 is as follows: A connecting post 131 is coaxially disposed in the center of the bottom cover 13. A first hollow groove is vertically disposed on the inner wall of the connecting post 131, and the first hollow groove is not connected to the upper end surface of the connecting post 131 so as to penetrate therethrough (this is to prevent the first limiting protrusion of the connecting rod 33 from slipping off the connecting post 131; the non-penetrating connection of the second hollow groove described below is similar and will not be repeated here). A first limiting protrusion that cooperates with the first hollow groove is disposed at the bottom of the outer wall of the connecting rod 33.

[0021] When the moving body 23 moves up along the inner wall of the fork 21 , it drives the rotating part 31 and moves the connecting rod 33 up inside the connecting column 131 .

[0022] In a specific implementation, the connection between the connecting rod 33 and the rotating part 31 is as follows: a second hollow groove is vertically formed on the inner wall of the connecting rod 33, and the second hollow groove is not connected to the upper end surface of the connecting rod 33 so as to penetrate through; a second limiting protrusion is formed at the bottom of the outer wall of the rotating part 31, which cooperates with the second hollow groove.

[0023] When the moving body 23 rises, the rotating part 31 rises along the inner wall of the connecting rod 33.

[0024] Specifically, the rotating part 31 has a hollow cylindrical structure. The movable body 23 and the rotating part 31 are connected as follows: A hollow part 24 for mounting the rotating part 31 is provided at the bottom of the lower end surface of the movable body 23. The upper part of the inner cavity of the hollow part 24 forms a first guide ring that is recessed in the outer diameter direction, a first guide protrusion that corresponds to the first guide ring is provided on the outer wall of the rotating part 31, and a female thread is formed on the inner wall of the rotating part 31.

[0025] Specifically, the extrusion part 32 includes a push plate 321 and a threaded rod 322 provided at the center of the lower end surface of the push plate 321. The outer wall of the threaded rod 322 is provided with a male thread that matches the female thread of the rotating part 31, and at least one side surface of the threaded rod 322 is formed with a vertical recess.

[0026] In a specific implementation, to prevent the extrusion part 32 from moving too far upward and falling off the moving body 23, a third hollow groove is provided on the lower end surface of the moving body 23 to allow the threaded rod 322 to move vertically. The shape of the third hollow groove corresponds to the shape of the threaded rod. A third limiting protrusion 323 is provided at the bottom of the vertically extending groove on the side wall of the threaded rod 322. The outer edge of the third limiting protrusion 323 extends beyond the side wall of the third hollow groove but does not extend beyond the top of the male thread of the threaded rod 322. The third limiting protrusion 323 can be configured as needed, but the shape and size of the outer edge of the third limiting protrusion 323 should not be larger than the shape and size of the thread to avoid interference with the inner wall of the rotating part 31 when the threaded rod 322 rotates. Taking the design shown in FIG. 4 as an example, one row of threads on at least one side of the threaded rod 322 is vertically notched (the notched portion is a vertically extending groove), and a third limiting protrusion 323 is provided at the bottom of this area.

[0027] The outer edge of the third limiting protrusion 323 does not exceed the top of the male thread of the threaded rod 322, so the setting of the third limiting protrusion 323 does not affect the rotation of the threaded rod 322. In addition, the outer edge of the third limiting protrusion 323 exceeds the side wall of the third hollow groove, so that when the pushing part 32 pushes the lipstick stick to the top of the moving body 23, the third limiting protrusion 323 accurately engages with the lower end surface of the moving body 23, preventing the pushing part 32 from falling off due to further upward movement.

[0028] Specifically, the outer diameter of the push plate 321 is the same as the inner diameter of the moving body 23 .

[0029] In a specific implementation, the extrusion part 32 has a T-shaped structure. During the first dispensing process, the push plate 321 remains at the bottom of the moving body 23, with its upper surface contacting the underside of the lipstick. When the lipstick is used up, the guide pin on the outer wall of the moving body 23 reaches the top of the rotating inner groove of the screw bundle 22. At this time, the rotating part 31 is driven by the bottom cover 13 and the connecting rod 33 to rotate. The rotating part 31 engages with the threaded rod 322 of the extrusion part 32, and the push plate 321 pushes the lipstick remaining on the moving body 23 upward.

[0030] The working principle or process of the two-stage retractable lipstick provided by this utility model is as follows: Primary feeding: Remove the top cover 12, and rotate the base 11 in the forward direction while holding the screw bundle 22. The guide pin of the moving body 23, the fork 21, and the screw bundle 22 cooperate to make the moving body 23 lift the lipstick along the guide pin of the fork 21. In this state, the lifting of the moving body 23 synchronously lifts the rotating part 31 at the bottom of the moving body 23, and the lifting of the rotating part 31 lifts the connecting rod 33.

[0031] Secondary feeding: While holding the base 11 or the screw bundle 22, rotate the bottom cover 13 in the forward direction. The first hollow groove of the connecting post 131 of the bottom cover 13 engages with the first limiting protrusion of the connecting rod 33, restricting its rotation, causing the connecting rod 33 to rotate in the forward direction. The second hollow groove of the connecting rod 33 engages with the second limiting protrusion of the rotating part 31, restricting its rotation, causing the connecting rod 33 to rotate the rotating part 31 in the forward direction. The female thread provided in the inner cavity of the rotating part 31 engages with the male thread of the threaded rod 322 of the extrusion part 32, causing the rotating part 31 to drive the extrusion part 32 to push up the remaining lipstick stick, enabling secondary use.

[0032] Finally, it should be noted that the above only shows preferred embodiments of the present invention, and does not limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features.
