Detailed Description

In order to further understand the present invention, the following detailed description will be made with reference to the following examples, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

Thus, the material can be used up to the maximum.

Example 1

Specifically, please refer to fig. 1-3 for the device of embodiment 1.

The embodiment 1 provides a multistage ejecting device, which at least comprises a group of first ejecting assemblies and a group of second ejecting assemblies, wherein the first ejecting assemblies comprise a spiral body 21 and a storage bin 22, and the storage bin 22 can move along the axial direction relative to the spiral body 21; the second pushing-out assembly comprises a piston 41, an elastic piece and a pushing piece, the piston 41 is arranged in the storage bin 22, the elastic piece generates driving force to the pushing piece when rotating, and the pushing piece pushes the piston 41 to ascend.

Specifically, the inner side of the spiral body 21 is provided with a thread, and the outer side of the storage bin 22 is provided with a first protrusion 221 matched with the thread.

Further, a positioning groove is further arranged on the inner side of the spiral body 21. When the first protrusion rotates to the positioning groove, positioning is realized, and when the first protrusion rotates in the same direction again, the storage 22 and the spiral body 21 are kept relatively static. At this point, rotation will cause the second ejection assembly to move.

In this embodiment, the elastic member includes a first guiding driving member 31 and a second guiding driving member 32, the first guiding driving member 31 has a first tooth at one end, at least one side of the first tooth is a bevel, the second guiding driving member 32 has a second tooth at an end adjacent to the first guiding driving member, and at least one side of the second tooth matches with the bevel.

The first guiding driving member 31 is disposed between the spiral body 21 and the storage bin 22, and the first guiding fixing member 31 has a first slot through which the first protrusion 221 passes to match with the thread.

In this embodiment, the first guiding driving member 31 may be screwed with the screw body 21, or the first guiding driving member 31 may be engaged with the screw body 21. As illustrated in fig. 1-3 for the snap-fit condition, it can be seen from the exploded view that the first guide driver 31 has a plurality of laterally projecting stripes adjacent the first teeth to facilitate the snap-fit.

As can be seen from the exploded view, the first teeth are distributed annularly.

Correspondingly, the second teeth are distributed annularly.

In this embodiment, the first and second teeth may be fully meshed.

The pushing part comprises a nut 44 and a screw 43 fixed inside the second guide driving part 32, the nut 44 is screwed with the screw 43, and a screw guide ring 42 is arranged between the screw 43 and the piston 41. The second guiding driving member 32 has an extending portion facing the first guiding driving member 31, the screw guiding ring 42 is sleeved on the extending portion, and then the screw 43 passes through the screw guiding ring 42, so as to control the position of the screw 43, prevent deviation, and ensure that the screw 43 can only move up and down.

In this embodiment, the first and second teeth are rigid teeth, and the elastic assembly further includes a spring 33 disposed between a base and the second guide driving member 32.

Specifically, the second guiding driving member 32 is a double-layer structure, a cavity is formed between two layers, the spring 33 is arranged in the cavity, and one end of the spring is in contact with the transverse connecting portion of the double-layer structure.

The second tooth may be disposed at an outer layer of the double-layer structure, and the protruding portion may be an inner layer of the double-layer structure.

In this embodiment, the base comprises an inner bottom 13, and the inner bottom 13 and the second guiding driving member 32 are arranged at intervals, specifically, the intervals are realized by the spring 33. The side wall of the inner bottom 13 is provided with a second slot, and the side wall of the second guiding driving piece 32 is provided with a second protrusion which is movably arranged in the second slot.

As can be seen in fig. 1 and 2, the intermediate bottom of the insole 13 is provided with a raised ring, which can be used to position the spring 33.

When the storage bin 22 is fixed and continues to rotate, and the first guide driving member 31 moves relative to the second guide driving member 32, for example, when the first guide driving member 31 rotates clockwise, the oblique plane of the first tooth generates pressure on the second tooth of the second guide driving member 32 due to the oblique plane of the first tooth below the first guide driving member 31, so that the spring 33 is compressed; on further rotation, the pressure of the first chamfered surface of the first guide driving member 31 on the second guide driving member 32 is reduced, and the spring 33 is relaxed, so that the second guide driving member 32 can be rotated controllably, that is, the nut 44 is rotated, thereby pushing the screw 43 to move upward. When the screw rod 43 is pushed forward, the pressure of the first guide driving piece 31 on the second guide driving piece 32 keeps increasing, decreasing, increasing and decreasing, so that the compression and relaxation movement is kept. During rotation, the gear can generate a 'click' sound. The other side of the first tooth and the second tooth can be selected to be a straight surface or a slant surface as required, so as to meet the requirements of the inner screw 43 and the piston 41 for retraction or not.

When the other side of the first tooth and the second tooth is a straight side: for example, when rotating counterclockwise, since the vertical surface of the gear of the first guide driving member 31 is in contact with the vertical surface of the second guide driving member 32, no relative movement is generated, the spring is not compressed any more, and the screw is not pushed out. Meanwhile, due to the counterclockwise rotation, the first protrusion 221 of the storage bin 22 is disengaged from the positioning groove and can descend along the spiral track.

When the other bevel of the first tooth and the second tooth: for example, counterclockwise, the storage bin 22 is lowered to the initial position as a whole, and then, the rotation is continued, and the first guide driving member 31 and the second guide driving member 32 are also rotated with respect to each other, thereby lowering the screw and the piston.

Further, a weight 34 is included in this embodiment, and the weight 34 is disposed in the cavity or in the insole 13. As shown in fig. 1, one end of the spring 33 is disposed in the weight member 34 in the embodiment of the present invention, so that the elasticity of the spring can be well adjusted. However, this is not intended to limit the positional relationship between the weight 34 and the spring 33, and the weight 34 and the spring 33 may be relatively independent.

Further, the base of this embodiment further includes an outsole 12, and the insole 13 is sleeved in the outsole 12. Furthermore, the multistage ejection device comprises a top cover 11, which top cover 11 covers the base (mainly the outsole 12).

Example 2

Referring to fig. 4-7, the structure of the multi-stage ejector according to the second embodiment of the present invention is shown. In the present embodiment, the same or similar components as those in embodiment 1 are denoted by the same reference numerals, have the same or similar functions, and description thereof is omitted, and specific features may be referred to embodiment 1, and embodiment 2 mainly describes differences from embodiment 1.

In this embodiment 2, the difference is that the second tooth is a compressible resilient tooth. Specifically, as seen in fig. 6 and 7, the second tooth 321 on the second guide driving member 32 'is an elastomer extending from the outer layer of the second guide driving member 32', and includes at least one inclined surface that is engageable with the first tooth. In addition, the number of the second teeth 321 is less than that of the first teeth, because the second teeth 321, which extend outward with the elastic body, occupy a plurality of positions as in embodiment 1.

In the present embodiment 2, since the second tooth 321 itself is an elastic body, when the second tooth 321 presses against the first tooth of the first guide driving member 31, elastic potential energy can be accumulated and released by the second tooth 321 itself, and thus a spring may not be required in the present embodiment 2.

Accordingly, in addition to the second tooth 321 being an elastomer, other parts, such as whether it has a straight surface or another inclined surface, can refer to embodiment 1.

In summary, the multi-stage ejecting apparatus provided by the present invention at least comprises a set of first ejecting assemblies and a set of second ejecting assemblies, wherein the first ejecting assemblies comprise a spiral body and a storage bin, and the storage bin can move axially relative to the spiral body; the second pushing assembly comprises a piston, an elastic piece and a pushing piece, the piston is arranged in the storage bin, the elastic piece generates driving force to the pushing piece when rotating, and the pushing piece pushes the piston to ascend. The invention can use up the material body to the maximum extent; moreover, a protective shell can be provided for the material bodies in the unfixed forms such as paste, liquid and the like; furthermore, the multi-stage ejection device of the present invention may be used in a variety of containers, including but not limited to cosmetics.
