Description

Technical Field

[0001] This utility model relates to the field of trash can technology, specifically a trash can with an expandable capacity. Background Technology

[0002] Trash cans, as an indispensable part of urban life, play a vital role. They are not only temporary storage places for garbage, but also important tools for maintaining urban sanitation and environmental cleanliness. There are many types of trash cans, which can be divided into plastic trash cans, metal trash cans, wooden trash cans, etc., according to their materials; and into household trash cans, public place trash cans, medical waste cans, etc., according to their uses.

[0003] In daily life and work, trash cans are essential tools for waste collection and disposal, and their capacity and ease of use directly impact environmental hygiene and user experience. However, traditional trash cans typically have a fixed capacity. When the amount of trash is large, frequent bag changes are often necessary. This not only increases the user's workload but can also lead to overflowing trash, especially when the trash can is full and a replacement bag cannot be obtained immediately, leaving the user with nowhere to put their trash, which is frustrating. Therefore, there is a need for a trash can that is simple in structure, easy to operate, and can be easily expanded. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional trash cans in the background art and to provide a more practical, convenient trash can that can increase the trash holding capacity in a timely manner.

Therefore, they should not be construed as limitations on this utility model.

[0024] Combination Figures 1 to 4 The trash can shown includes an outer shell 1, a bottom bucket 2 inside the outer shell 1, an inner cylinder 3 slidably disposed inside the bottom bucket 2, a lifting mechanism 4 on one side of the bottom bucket 2 for driving the inner cylinder 3 to move up and down, the lifting part of the lifting mechanism 4 is connected to the inner cylinder 3, a battery for providing power to the lifting mechanism 4 is disposed at the bottom of the bottom bucket 2, and a top cover 5 is installed on the top of the inner cylinder 3; a lifting switch 6 for controlling the lifting mechanism 4 is disposed on the side of the outer shell 1.

[0025] Example 1

[0026] like Figure 2 As shown, the lifting mechanism 4 is an electric push rod 41 installed on one side of the bottom barrel 2. One end of the telescopic rod of the electric push rod 41 is provided with a connecting rod 42, which is fixedly connected to the inner cylinder 3. The electric push rod 41 is located inside the outer casing 1. In use, the electric push rod 41 can be activated via the lifting switch 6. The telescopic rod of the electric push rod 41 drives the connecting rod 42 and the inner cylinder 3, which is fixedly connected to the connecting rod 42, to move upwards. For example... Figure 4As shown, guide keys 31 are symmetrically arranged on the bottom outer surface of the inner cylinder 3, and guide grooves matching the guide keys 31 are opened on the inner side wall of the bottom bucket 2. The inner cylinder 3 moves upward under the guidance of the guide grooves to ensure the stability of the inner cylinder 3's rise. Thus, the inner cylinder 3 can be driven upward by the lifting mechanism 4, thereby expanding the capacity of the trash can. In addition, the rising height of the inner cylinder 3 is less than the distance between the top opening of the bottom bucket 2 and the bottom surface of the bottom bucket 2, so as to avoid the trash inside the bucket from leaking into the outer shell 1.

[0027] Example 2

[0028] like Figure 3 As shown, the lifting mechanism 4 is a drive motor 43 installed on one side of the bottom bin 2. The output end of the drive motor 43 is connected to a lead screw 44, and a lifting block 45 is threadedly connected to the lead screw 44. The lifting block 45 is fixedly connected to the inner cylinder 3. One end of the lead screw 44 is rotatably installed on the outer shell 1, and the drive motor 43 is located inside the outer shell 1. In use, the drive motor 43 can be started by the lifting switch 6. The drive motor 43 drives the lead screw 44 to rotate, and then the lifting block 45 on the lead screw 44 drives the inner cylinder 3, which is fixedly connected to it, to move upward, thereby expanding the capacity of the trash can.

[0029] Example 3

[0030] When this utility model is used as a small trash can in an office or home, the bottom of the outer shell 1 is provided with a charging port for the storage battery. The charging port is electrically connected to the storage battery through a wire. The storage battery can be charged through the charging port to store electrical energy, so as to provide power for the lifting mechanism. The top cover 5 is installed on the top of the inner cylinder 3 by threads. Thus, when a trash bag is placed in the trash can, the opening of the trash bag can be pressed tightly against the top of the inner cylinder 3 by the threaded installation of the top cover 5, preventing the trash bag from falling into the trash can.

[0031] Example 4

[0032] like Figure 1 and Figure 4As shown, the top surface of the top cover 5 is provided with a rotatable flip cover 51, and solar panels 52 are provided on both sides of the flip cover 51. The solar panels 52 are electrically connected to the storage battery. The outer side of the inner cylinder 3 is provided with a wiring clip 32, and a first line connected to the storage battery is laid in the wiring clip 32. The top cover 5 is provided with a second line connected to the solar panels 52. The first line and the second line are connected. When this utility model is placed outdoors as a large trash can, the solar panels 52 on its top cover 5 can absorb light energy and convert it into electrical energy, which is stored in the storage battery. When installing the top cover 5, the second line is first connected to the first line, and the second line and the first line can be connected by a connector. Then the top cover 5 is installed on the top of the inner cylinder 3 by threads or a buckle, so that the storage battery can store electrical energy. When disposing of trash, the trash can be put into the trash can from the opening of the cover by rotating the flip cover 51.

[0033] Working principle: When the space inside the trash can is insufficient, the lifting mechanism 4 can be activated by the lifting switch 6. The lifting mechanism 4 will drive the inner cylinder 3 to move upward, thereby expanding the space inside the trash can and solving the problem of insufficient space for timely trash disposal. When the trash can is to be emptied, the top cover 5 can be opened to remove the trash directly.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
