DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-6 The present invention provides a technical solution: a garbage classification box, which includes: an outer barrel body 1, a rotating shaft 5, a supporting cylinder 2, a pushing mechanism, a pulling mechanism and a rotating positioning device. The outer barrel body 1 has a accommodating cavity. A top cover 3 that can move in a vertical direction but cannot rotate in a circumferential direction is arranged on the top of the outer barrel body 1. A circular garbage opening 301 for inverting garbage or taking out garbage is opened on the top cover 3. The inner diameter of the circular garbage opening 301 is 1-2 cm larger than the outer diameter of the garbage can 6. 3-4 protrusions 302 extend downward from the bottom of the top cover 3 to prevent odor from leaking out. The rotating shaft 5 is rotatably installed in the center of the accommodating cavity. The first end of the rotating shaft 5 is rotatably installed in the center of the bottom of the outer barrel body 1, and the second end passes through the top cover 3 and is connected There is a knob 4, on which 3 or 4 pointing plates 401 are arranged, and 3 or 4 support tubes 2 are arranged, on which a trash can 6 is placed, and the support tube 2 is connected to the vertical end of the rotating shaft 5 through a connecting piece, the inner diameter of the support tube 2 is 1-2 cm larger than the outer diameter of the trash can 6, the bottom of the support tube 2 is a through-through structure, and a flange 201 is arranged along the edge for supporting the trash can 6, the pushing mechanism is located directly below the trash port 301, and is used to push the trash can 6 out of the trash port 301, the pulling mechanism has a pulling force that makes the top cover 3 vertically downward, so that the protrusion 302 is covered with the mouth of the trash can 6, and the rotating positioning device makes the rotating shaft 5 have a resistance to rotation, that is, it is positioned when the trash can 6 rotates to the trash port 301.

[0041] When using the garbage classification box provided in the present embodiment, the user lifts up the knob 4, the tension mechanism is compressed by force, the protrusion 302 is separated from the mouth of the garbage bin 6, and then the knob 4 is turned to rotate the shaft 5, so that the three or four garbage bins 6 rotate around the axis. When one of the garbage bins 6 rotates to just below the garbage port 301, the rotation is stopped and the hand is released. Due to the effect of the rotating positioning device, the above-mentioned one garbage bin 6 is located just below the garbage port 301 and will not shake easily. At the same time, the remaining protrusions 302 will also re-seal the remaining garbage bins 6 under the pulling-down action of the garbage mechanism to prevent the leakage of odor. At this time, the user can pour the designated garbage into the corresponding garbage bin 6 from the garbage port 301. When pouring out the garbage, the garbage bin 6 located at the bottom of the garbage port 301 can be easily pushed out by the pushing mechanism to realize the dumping of the garbage. The garbage classification box integrates multiple types of garbage bins 6 in one, and realizes garbage classification by rotating and transposing. On the one hand, it saves space, and on the other hand, it is easy to operate, providing convenience for home life.

[0042] It should be noted that there are 3 or 4 garbage cans 6 in the garbage classification box, and the garbage cans 6 are used to hold different types of garbage, which can be dry garbage, wet garbage, hazardous garbage and recyclable garbage.

[0043] like Figure 1 As shown, 3 or 4 pointing plates 401 are distributed on the outside of the knob 4, on which words such as wet garbage, dry garbage, hazardous garbage or recyclable garbage are pasted.

[0044] Specifically, the number of the pointing plates 401 and the trash cans 6 are consistent, and they are located one-to-one on the same vertical line. The type of garbage marked on the pointing plate 401 is the type of garbage that can be led by the corresponding trash can 6 below, ensuring accurate classification of different types of garbage.

[0045] like Figure 3 and Figure 6 As shown, the bottom of the knob 4 is rotatably connected to a sleeve 14 through a bearing 15. The sleeve 14 is covered on the outside of the portion of the rotating shaft 5 extending from the outer barrel body 1. The bottom end of the sleeve 14 is fixed to the outer surface of the top of the top cover 3, so that the top cover 3 can move in the vertical direction but cannot rotate in the circumferential direction. The specific structure is: a limiting protrusion 303 is arranged on the bottom edge of the top cover 3; a limiting opening 101 is arranged on the inner edge of the top of the outer barrel body 1; the limiting protrusion 303 is located in the limiting opening 101, and can slide in the vertical direction under the action of external force.

[0046] Specifically, the knob 4 is pulled up to disengage the protrusion 302 from the mouth of the trash can 6, and the knob 4 can be rotated at this time. Due to the setting of the bearing 15, the knob 4 will not drive the top cover 3 to rotate during the rotation process, ensuring that the top cover 3 will not rotate and can only move in the vertical direction under the action of external force, thereby improving the structural stability.

[0047] like Figure 3 As shown, the ejection mechanism includes: a limit sleeve 9, a support rod 8 and a pedal rod 7. The limit sleeve 9 is fixed under the support tube 2. The support rod 8 passes through the limit sleeve 9, and its top is close to or in contact with the bottom of the trash can 6. The first end of the pedal rod 7 is hingedly connected to the bottom end of the support rod 8, and the second end extends to the outside of the outer barrel body 1. The pedal rod 7 has a bending structure, and the bending point of the bending structure is hingedly connected to the outer barrel body 1.

[0048] Specifically, the outer diameter of the support rod 8 is smaller than the inner diameter of the limiting sleeve 9. The limiting sleeve 9 is used to limit the radial deflection angle of the support rod 8 so that the support rod 8 moves upward under the action of external force. When in use, the pedal rod 7 is stepped on and the support rod 8 is pushed upward under the action of the lever principle, thereby finally pushing out the trash can 6, facilitating the removal of the trash can 6 and completing the dumping of the garbage.

[0049] like Figure 3As shown, the tension mechanism includes: a tension member 13 and a connecting protrusion. The tension member 13 is sleeved on the rotating shaft 5, and its first end is connected to the bottom of the top cover 3. The connecting protrusion is fixed on the outer wall of the rotating shaft 5 for connecting the second end of the tension member 13.

[0050] Specifically, the tension member 13 can be a specific component such as a tension spring, an elastic rubber band, etc., which is used to provide tension so that the top cover 3 in a natural state has a tendency to move downward, so that the protrusion 302 can cover the mouth of the trash can 6. The protrusion 302 is a circular structure, and its outer diameter is equal to the inner diameter of the mouth of the trash can 6.

[0051] like Figure 3 and Figure 4 As shown, the rotation positioning device includes: a first magnet piece 11, a circular tube 10 and a second magnet piece 12. The first magnet pieces 11 are provided with 4 or 5 pieces, which are distributed on the outer wall of the rotating shaft 5 at equal angles with the axis of the rotating shaft 5 as the center of the circle. The circular tube 10 is covered on the outer side of the rotating shaft 5 and its bottom end is fixed to the bottom of the outer barrel body 1. The second magnet pieces 12 are provided with 4 or 5 pieces, which are distributed on the inner wall of the circular tube 10 at equal angles with the axis of the rotating shaft 5 as the center of the circle. The number of the second magnet pieces 12 is equal to that of the first magnet pieces 11, and they are located at the same horizontal height, and the magnetic pole directions of the first magnet piece 11 and the second magnet piece 12 are opposite.

[0052] Specifically, due to the balancing effect of forces, in a static state, the single first magnet piece 11 and the single second magnet piece 12 are in a one-to-one correspondence, that is, they are balanced in the uniform radial extension direction of the rotating shaft 5. Every time the rotating shaft 5 rotates an angle (this angle refers to the angle required to complete the replacement of a trash can 6), this balance is instantly broken. After the replacement of a trash can 6 is completed, the balance is re-found under the action of the magnetic force of the first magnet piece 11 and the second magnet piece 12, so that the rotating shaft 5 is obstructed during the rotation process, ensuring that the corresponding trash can 6 will not shake or deflect during the garbage collection process, thereby achieving precise positioning.

[0053] It should be noted that the number of the pointing plates 401 , the supporting tubes 2 , and the trash cans 6 is equal, and the number of the pointing plates 401 is one less than the number of the first magnet sheets 1 .

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
