Description

Technical Field

[0001] The invention belongs to the technical field of recycling equipment, and in particular relates to a daily debris recycling box. Background Art

[0002] Daily sundries include clothes, shoes, toys and other metal daily necessities that are not used or depreciated. If these daily sundries are discarded in a trash can, it will cause serious waste and garbage disposal burden. Therefore, a recycling bin specifically for recycling is generally set up. The internal layout of the daily sundries recycling bin in the prior art is roughly the same as that of a traditional garbage sorting bin. According to the types of daily sundries, the recycling bin is divided into several internal chambers isolated from each other. In the prior art, the internal structure of the daily sundries recycling bin is simple. When a large amount of sundries are accumulated, a gravity superposition squeezing effect will be formed on the sundries part at the bottom, that is, the sundries at the bottom of the recycling bin will be squeezed, thereby narrowing the gaps between the parts, resulting in poor air circulation inside the recycling bin. Some of the recycled daily sundries have dirty surfaces. Over time, the interior of the recycling bin will ferment, resulting in a foul smell, which seriously affects the storage and recycling of daily sundries in the recycling bin. In addition, the air vents of the existing recycling bins are easily blocked by the squeezed and superimposed sundries layer, affecting the ventilation efficiency. Therefore, improvement is urgently needed. Summary of the invention

The lower partition plate 2 and the lower partition plate 1 are respectively just adapted to abut against the bottom of the upper partition plate 1 and the upper partition plate 2. An air inlet hole is provided at the bottom of the placement box and passes through the outer side. A plurality of groups of exhaust holes are horizontally passed through the lower partition plate 1 and the lower partition plate 2 at the top of the inner wall of the placement box. The spring is movably sleeved on the outer surface of the piston, and the two ends of the spring are elastically connected to the piston and the sealing cylinder respectively.

[0005] As a preferred solution of the present invention, the lower partition one and the lower partition two divide the inner cavity of the storage box into storage area one, storage area two and storage area three from left to right, the volume value of storage area two is the largest, and three groups of discharge ports are opened at the bottom of the back side of the storage box, which are respectively connected with storage area one, storage area two and storage area three.

[0006] As a preferred solution of the present invention, a discharge door is movably hinged on the back of the placement box, and three groups of rectangular protrusions are provided on the side of the discharge door facing the discharge port, and are respectively adapted to engage with the three groups of discharge ports, and a fixing groove is provided on the top of the discharge door. A telescopic rod located above the discharge door is also installed inside the placement box, and a fixing plate is fixedly installed on the telescopic end of the telescopic rod, and the fixing plate is adapted to be inserted downward into the fixing groove.

[0007] As a preferred solution of the present invention, a sealing ring is glued to the outer side of each group of the rectangular protrusions, and the sealing ring is extruded and arranged between the discharge door and the back side of the placement box.

[0008] As a preferred solution of the present invention, a plurality of protective covers are installed on the inner wall of the placement box, the protective covers cover the outer side of the sealing cylinder, and the outer surface of the protective covers is provided with two upper and lower groups of mutually symmetrical inclined surfaces.

[0009] As a preferred solution of the present invention, the portion of the heat-conducting column located on the outer surface of the inner cavity of the sealing tube is provided with a plurality of heat-conducting ring structures equidistantly distributed along the axis of the heat-conducting column, the outer end of the heat-conducting column is welded to the heat exchange plate, and a gap is left between the heat exchange plate and the side of the placement box.

[0010] As a preferred solution of the present invention, both left and right sides of the placement box are fixedly connected with rain shield strips located above the heat exchange plate, and the top of the rain shield strip is provided with an inclined surface.

[0011] As a preferred solution of the present invention, the metal rings are arranged in three groups which are concentrically distributed inside and outside, the sizes of the three groups of metal rings decrease from outside to inside, and the axial cross-section shape of the metal rings is an isosceles trapezoid.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. This device has been redesigned, and the inner cavity of the storage box is divided from left to right into storage area 1, storage area 2 and storage area 3 by lower partition 1 and lower partition 2. Among them, the volume value of storage area 2 is the largest. A sealing tube and a sealing sleeve are provided with a piston, and the lower partition 1 and the lower partition 2 are connected by the piston, so that the lower partition 1 and the lower partition 2 can slide freely in the horizontal direction and dynamically change the volume of storage area 1, storage area 2 and storage area 3. The condition for triggering the volume change of the three groups of storage areas is the degree of light received by the heat exchange plate and the metal ring, that is, the real-time temperature of the heat exchange plate. The metal ring transmits the heat generated by the sunlight to the kerosene in the sealing cylinder through the heat-conducting column, causing the kerosene to expand thermally, pushing the piston to drive the lower partition one or the lower partition two to move horizontally. At this time, the volume value of the storage area one or the storage area three will increase, thereby reducing the stacking height of the metal or plastic debris located therein, reducing the weight of the debris at the bottom of the storage area one or the storage area three, avoiding the bottom superposition effect caused by the increase in the stacking height of the daily debris, and increasing the gap between the daily debris in the storage box, which is beneficial to improving the air circulation efficiency of the inner cavity of the storage box.

[0014] 2. Then, through the movement of the lower partition 1 and the lower partition 2, the volume of the storage area 2 in the middle is continuously reduced, and the clothes, shoes and other daily sundries therein are compressed. Since the volume of the storage area 2 is the largest, the clothes, shoes and other daily sundries are not greatly affected. However, due to the movement of the lower partition 1 and the lower partition 2, the original positions of the various parts of the clothes, shoes and other daily sundries are changed, and the gaps between the various parts of the clothes, shoes and other daily sundries are increased. As the temperature of the heat exchange plate drops, the spring drives the piston, the lower partition 1 and the lower partition 2 to reset. At this time, the bottom of each storage area returns to its original position to prevent the daily sundries from being squeezed and agglomerated.

[0015] 3. The device also opens exhaust holes on the top of the left and right sides of the placement box and the top of the surface of the lower partition one and the lower partition two. The outside air can enter the inner cavity of the placement box along the air inlet holes and drive the turbid air on the surface of daily necessities. At this time, the air is heated by the heat exchange plate and the metal ring and heated near the exhaust holes opened on both sides of the placement box. According to the "chimney effect", the air discharged from the exhaust holes will increase in temperature and increase its speed upward, and generate negative pressure near the exhaust holes toward the outside of the placement box, which helps to increase the air flow rate. On rainy days, due to the drop in the temperature of the heat exchange plate, the air flow rate near the exhaust holes is just reduced to prevent moisture from entering the inner cavity of the placement box.

DETAILED DESCRIPTION

[0027] 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.

[0028] like Figures 1 to 10As shown, an embodiment of the present invention provides a household debris recycling box, including a placement box 1, a feed box 2 is installed on the top of the placement box 1, an upper partition 1 6 and an upper partition 2 7 are installed horizontally and equidistantly on the inner wall of the feed box 2, a feed door 1 3, a feed door 2 4 and a feed door 3 5 are rotatably installed on the inner wall of the feed box 2, a group of sealing cylinders 15 are fixedly installed on the left and right sides of the inner wall of the placement box 1, an internal sealing sleeve of the sealing cylinder 15 is provided with a piston 16 and a spring 17, the inner cavity of the sealing cylinder 15 is also filled with kerosene 19 located at one end inside the piston 16, one end of the sealing cylinder 15 that passes through the inner wall of the placement box 1 is fixedly connected to a heat-conducting column 18 located in its inner cavity, and an outer side of the heat-conducting column 18 is provided with a sealing sleeve 15. The end is fixedly connected with a heat exchange plate 9, and the surface of the heat exchange plate 9 is fixedly connected with multiple groups of metal rings 10. The outer end of a group of pistons 16 on the right side is fixedly connected with a lower partition plate 21, and the outer end of a group of pistons 16 on the left side is fixedly connected with a lower partition plate 1 20. The lower partition plate 21 and the lower partition plate 1 20 are respectively adapted to abut against the bottom of the upper partition plate 1 6 and the upper partition plate 2 7. The bottom of the placement box 1 is provided with an air inlet hole 13 that penetrates to the outside, and the top of the inner wall of the placement box 1 is provided with multiple groups of exhaust holes 11 that horizontally penetrate the lower partition plate 1 20 and the lower partition plate 21. The spring 17 is movably sleeved on the outer surface of the piston 16, and the two ends of the spring 17 are elastically connected to the piston 16 and the sealing cylinder 15 respectively;

[0029] The device has been redesigned, and the inner cavity of the storage box 1 is divided into storage area 1, storage area 2 and storage area 3 from left to right by using lower partition 1 20 and lower partition 2 21, among which the volume value of storage area 2 is the largest. The sealing sleeve 15 is provided with a piston 16, and the lower partition 1 20 and the lower partition 2 21 are connected by the piston 16, so that the lower partition 1 20 and the lower partition 2 21 can slide freely in the horizontal direction and dynamically change the volume of storage area 1, storage area 2 and storage area 3. The condition for triggering the volume change of the three groups of storage areas is the degree of light exposure to the heat exchange plate 9 and the metal ring 10, that is, the real-time temperature of the heat exchange plate 9, which is controlled by the heat exchange plate 9. The heat generated by the sunlight to which the metal ring 10 is subjected is transmitted to the kerosene 19 in the sealing tube 15 through the heat-conducting column 18, and the kerosene 19 is caused to generate thermal expansion, thereby pushing the piston 16 to drive the lower partition 1 20 or the lower partition 2 21 to move horizontally. At this time, the volume value of the storage area 1 or the storage area 3 will increase, thereby reducing the stacking height of the metal or plastic debris located therein, reducing the weight of the debris located at the bottom of the storage area 1 or the storage area 3, avoiding the bottom superposition effect caused by the increase in the stacking height of the daily debris, and increasing the gap between the daily debris in the storage box 1, which is beneficial to improving the air circulation efficiency of the inner cavity of the storage box 1.

[0030] Then, through the movement of the lower partition 1 20 and the lower partition 2 21, the volume of the storage area 2 located in the middle is continuously reduced, and the clothes, shoes and other daily sundries located therein are compressed. Since the volume of the storage area 2 is the largest, the clothes, shoes and other daily sundries are not greatly affected. However, due to the movement of the lower partition 1 20 and the lower partition 2 21, the original positions of the various parts of the clothes, shoes and other daily sundries are changed, and the gaps between the various parts of the clothes, shoes and other daily sundries are increased. As the temperature of the heat exchange plate 9 drops, the spring 17 drives the piston 16, the lower partition 1 20 and the lower partition 2 21 to reset. At this time, the bottom of each storage area returns to its original position to prevent the daily sundries from being squeezed and forming lumps.

[0031] The lower partition 1 20 and the lower partition 2 21 divide the inner cavity of the storage box 1 into storage area 1, storage area 2 and storage area 3 from left to right, and the volume of storage area 2 is the largest. The bottom of the back of the storage box 1 is provided with three groups of discharge ports 14 respectively connected with the storage area 1, storage area 2 and storage area 3;

[0032] The three groups of storage areas can be flexibly allocated according to the specific conditions of actual use, and the discharge port 14 connected to the storage area is responsible for discharging the accumulated daily sundries.

[0033] Among them, a discharge door 22 is movably hinged on the back of the placement box 1. Three groups of rectangular protrusions are provided on the side of the discharge door 22 facing the discharge port 14, and are respectively adapted to engage with the three groups of discharge ports 14. A fixing groove 23 is opened on the top of the discharge door 22. A telescopic rod 24 located above the discharge door 22 is also installed inside the placement box 1. A fixing plate 25 is fixedly installed at the telescopic end of the telescopic rod 24. The fixing plate 25 is adapted to be inserted into the fixing groove 23 downward;

[0034] like Fig. 9 , Fig.10 As shown, the discharge door 22 is in a vertical state, and the fixing groove 23 opened on its top is just inserted into the fixing plate 25, and the discharge door 22 is fixed to block the discharge port 14. When the telescopic rod 24 drives the fixing plate 25 to move upward, the discharge port 14 can rotate freely and open the discharge port 14.

[0035] Among them, the outer side of each set of rectangular protrusions is glued with a sealing ring 26, and the sealing ring 26 is extruded and arranged between the discharge door 22 and the back side of the placement box 1;

[0036] The sealing ring 26 is made of a rubber block, and its function is to provide auxiliary sealing for the discharge port 14 and the rectangular protrusion on the front of the discharge door 22, thereby preventing rainwater from entering the inner cavity of the storage box 1 along the discharge port 14 on rainy days.

[0037] The inner wall of the placement box 1 is equipped with multiple sets of protective covers 12, which cover the outer side of the sealing cylinder 15. The outer surface of the protective cover 12 is provided with two sets of mutually symmetrical inclined surfaces.

[0038] The protective cover 12 is wrapped around the outer surface of the sealing cylinder 15 to prevent the sealing cylinder 15 from being affected by household debris. The inclined surface of the protective cover 12 is conducive to the household debris sliding downward along the surface thereof.

[0039] The heat-conducting column 18 is located on the outer surface of the inner cavity of the sealing tube 15, and is provided with a plurality of heat-conducting ring structures equidistantly distributed along the axis of the heat-conducting column 18. The outer end of the heat-conducting column 18 is welded to the heat exchange plate 9, and a gap is left between the heat exchange plate 9 and the side of the placement box 1.

[0040] The heat-conducting ring structure distributed on the outside of the heat-conducting column 18 can quickly transfer the heat of the heat-conducting column 18 to the kerosene 19. The narrow gap between the heat exchange plate 9 and the placement box 1 helps to increase the flow rate of the air discharged from the exhaust hole 11 and improve the air circulation speed in the inner cavity of the placement box 1.

[0041] The device also opens exhaust holes 11 on the top of the left and right sides of the placement box 1 and the top of the surface of the lower partition 1 20 and the lower partition 2 21. The outside air can enter the inner cavity of the placement box 1 along the air inlet hole 13 and drive the turbid air on the surface of the daily necessities. At this time, the air is heated by the heat exchange plate 9 and the metal ring 10 and is heated near the exhaust holes 11 opened on both sides of the placement box 1. According to the "chimney effect", the air discharged along the exhaust holes 11 will increase in temperature and increase its speed upward, and a negative pressure will be generated near the exhaust holes 11 toward the outside of the placement box 1, which helps to increase the air flow rate. On rainy days, due to the decrease in the temperature of the heat exchange plate 9, the air flow rate near the exhaust holes 11 is just reduced to prevent moisture from entering the inner cavity of the placement box 1.

[0042] The left and right sides of the placement box 1 are fixedly connected with rain shield strips 8 located above the heat exchange plate 9, and the top of the rain shield strips 8 is provided with an inclined surface;

[0043] The inclined design of the top of the rain shield strip 8 just blocks the raindrops left on both sides of the storage box 1 and prevents them from entering the inner cavity of the storage box 1 along the exhaust hole 11.

[0044] The metal rings 10 are arranged in three groups which are concentrically distributed inside and outside. The sizes of the three groups of metal rings 10 decrease from outside to inside. The axial cross-section of the metal rings 10 is an isosceles trapezoid.

[0045] The three groups of metal rings 10 can increase the contact area with sunlight and improve the heat exchange efficiency. The isosceles trapezoidal axial cross-section design allows the light incident on the surface of the metal ring 10 to be reflected to other areas on the surface of the metal ring 10, thereby improving the light utilization efficiency.

[0046] Working principle:

[0047] First, determine the storage types of daily necessities in the three groups of storage areas in the inner cavity of the placement box 1, place metal sundries in the storage area 1 or the storage area 3, place clothing sundries in the storage area 2, and place plastic sundries in the storage area 3 or the storage area 1. The front of the feed box 2 is provided with an inclined surface, which is just overlapped with the feed door 1 3, the feed door 2 4 and the feed door 3 5. When the user needs to throw daily necessities into the placement box 1, push the feed door 3 5 backwards and open the front opening of the feed box 2 to throw daily necessities into the inner cavity of the placement box 1 according to the type;

[0048] Then, the two groups of heat exchange plates 9 and metal rings 10 on both sides of the storage box 1 are exposed to sunlight and generate heat. When the heat exchange plates 9 and metal rings 10 on the right side are exposed to direct sunlight, the heat-conducting column 18 on the right side absorbs the heat from the heat exchange plates 9 and causes the kerosene 19 to expand in volume due to the heat, pushing the piston 16 on the right side toward the left, stretching the spring 17, and driving the lower partition plate 2 21 to move to the right. At this time, the volume of the storage area 2 decreases, and the volume of the storage area 3 increases. The clothes and other sundries in the storage area 2 are squeezed, and the storage volume of the metal or plastic sundries stored in the storage area 3 on its right side increases, thereby reducing the height of the sundries stacked therein and reducing the weight of the sundries at the bottom of the storage area 3.

[0049] Then, when the heat exchange plate 9 on the left side is directly exposed to sunlight, its surface temperature rises rapidly, and acts on the kerosene 19 on the left side through the heat-conducting column 18 on the left side, causing it to expand thermally, and driving the piston 16 on the left side to push the lower partition 1 20 to the right, the volume of the storage area 2 decreases, the volume of the storage area 1 increases, the clothes and other sundries in the storage area 2 are squeezed, and the storage volume of the plastic or metal sundries stored in the storage area 1 on its left side increases, thereby reducing the height of the sundries stacked therein and reducing the weight of the sundries at the bottom of the storage area 1;

[0050] Then, when the sun sets or it is cloudy and rainy, the temperature of the heat exchange plate 9 drops, causing the volume of the kerosene 19 to recover. At this time, the stretched spring 17 drives the piston 16 to reset, so that the lower partition 1 20 and the lower partition 2 21 are reset;

[0051] Then, the gaps between the daily necessities placed at the bottom of the three groups of storage areas are adjustable, and air is taken in through the air inlet 13 and exhausted through the air outlet 11, forming an internal and external gas circulation of the storage box 1, and the heat exchange plate 9 and the metal ring 10 are directly exposed to sunlight, so that the air temperature near the air outlet 11 increases, thereby generating a "chimney effect" in which air flows upwards faster between the gaps between the two sides of the storage box 1 and the heat exchange plate 9, thereby accelerating the air circulation efficiency of the inner cavity of the storage box 1;

[0052] Finally, when the inner cavity of the storage box 1 is full of daily necessities, the telescopic rod 24 is started to drive the fixing plate 25 to move upward, so that the fixing plate 25 is disengaged from the fixing groove 23, the discharge door 22 is rotated upward, the discharge port 14 is opened, and the daily necessities can be discharged.
