Description

[Technical Field]

[0001] This invention relates to a cyclone separator and its associated waste collector. [Background Technology]

[0002] Existing separators for separating garbage from airflow include a cylindrical cup, a top cover, and an air inlet extending from the cup. These separators are typically installed on garbage bins, with the interior connected to the bin. The airflow carrying debris and other garbage struggles to form an effective vortex within the cup. After entering the separator, the airflow exits directly from the outlet on the top cover. Heavier or larger pieces of garbage, carried by the airflow, fall into the garbage bin under their own weight, while other garbage flows further out of the cup with the airflow. Existing separators are ineffective at separating garbage from the airflow and require improvement. [Summary of the Invention]

Detailed Implementation Methods

[0036] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0037] Reference Figures 1 to 7The diagram illustrates the cyclone separator 10 and its associated waste collector according to this patent application. The cyclone separator 10 is used for waste separation and includes a cup body 2, a top cover 3 located on the top side of the cup body 2, and an air inlet port 100. The cup body 2 is cylindrical. The top cover 3 is provided with a cyclone tube section 30, which extends downward into the cup body 2. The air inlet port 100 extends integrally from the cup body 2 and is perpendicular to the central axis A of the cyclone separator 10. The airflow entering the cup body 2 through the air inlet port 100 can form a cyclone rotating around the cyclone tube section 30, and can enter the cyclone tube section 30 from its lower end and flow out of the cup body 2. The presence of the cyclone tube section 30 in this application facilitates the more effective formation of a cyclone rotating around the cyclone tube section 30 within the cup body 2. Under centrifugal force, the garbage carried in the cyclone airflow is easily separated from the cyclone airflow, thus the cyclone separator 10 has a better separation effect on garbage in the airflow.

[0038] The upper cover 3 also includes a base plate 31 and an air outlet 32 ​​connected to the cyclone tube section 30. The cyclone tube section 30 is located inside the cyclone separator 10, and the air outlet 32 ​​is located outside the cyclone separator 10. The cyclone tube section 30 extends downward from the base plate 31, and the air outlet 32 ​​extends upward from the base plate 31. The air inlet port 100 is arranged tangentially relative to the cup body 2, that is, the air inlet port 100 is approximately tangential to the cup body 2, so that the airflow entering the cup body 2 from the air inlet port 100 forms a cyclone airflow rotating around the cyclone tube section 30. During the rotation, the airflow enters the cyclone tube section 30 upward through the lower end of the cyclone tube section 30. The presence of the cyclone tube section 30 enhances the rotation of the airflow; otherwise, the airflow would easily flow almost directly to the air outlet 32. Finally, the airflow is discharged from the cyclone separator 10 through the air outlet 32. For heavy and dense waste, it is easier for it to separate from the cyclone airflow and gradually slide down along the inner wall of the cup body 2. The air outlet port 32 and the air inlet port 100 can also be fitted with sealing rings (not shown) to ensure a sealed connection with the corresponding pipes.

[0039] The top cover 3 is detachably mounted on the upper end of the cup body 2. A latching structure is provided between the top cover 3 and the cup body 2 to fasten the upper end of the cup body 2 to the top cover 3. The latching structure includes a slot 330 located at one of the upper ends of the cup body 2 and the top cover 3, and a latching protrusion 200 located at the other of the upper ends of the cup body 2 and the top cover 3. The latching protrusion 200 engages with the slot 330. This design reduces the manufacturing cost of the cyclone separator 10 and facilitates the replacement of the top cover 3.

[0040] The cup body 2 has a cylindrical part 20 and a conical part 21 located below the cylindrical part 20. The conical part 21 is integrally connected to the lower end of the cylindrical part 20. The air inlet port 100 extends integrally from the cylindrical part 20. The conical part 21 gradually tapers downward (i.e., the conical part 21 is a conical shape with a smaller radial dimension as it goes down; in short, the conical part 21 is thicker at the top and thinner at the bottom). The slot 330 is provided at the upper end of the cylindrical part 20 and one of the upper cover 3. The buckle protrusion 200 is provided at the upper end of the cylindrical part 20 and the other of the upper cover 3. The cyclone tube section 30 extends downward into the cylindrical part 20. The cyclone tube section 30 does not extend downward beyond the cylindrical part 20. The lowest point of the cyclone tube section 30 is higher than the highest point of the conical part 21. The cyclone tube section 30 extends downward beyond the lowest point of the inner cavity of the air inlet port 100. This design facilitates the formation of a strong cyclone within the cylindrical section 20. Based on the cylindrical section 20, the waste accompanying the cyclone airflow is more smoothly separated from the cyclone airflow and falls downwards along the inner wall of the cylindrical section 20, which helps to reduce the proportion of waste that is not separated from the airflow.

[0041] The top cover 3 is detachably mounted on the upper end of the cylindrical part 20, the upper end of the cylindrical part 20 forming the upper end of the cup body 2. The top cover 3 also has a peripheral wall 33 extending downward from the base plate 31. The peripheral wall 33 fits onto the upper end of the cylindrical part 20. A slot 330 is provided on one of the upper end of the cylindrical part 20 and the peripheral wall 33, and a buckle protrusion 200 is provided on the other of the upper end of the cylindrical part 20 and the peripheral wall 33. The radial dimension of the cylindrical part 20 is relatively constant, which is suitable for forming a sufficiently tight fit with the peripheral wall 33. With the help of the buckle mechanism and the peripheral wall 33, the cylindrical part 20 is also easier to assemble with the top cover 3.

[0042] A latching protrusion 200 is located at the upper end of the cylindrical section 20 and protrudes from the outer circumferential surface of the cylindrical section 20. A latching groove 330 is located on the peripheral wall 33. The latching groove 330 is a through groove located on the peripheral wall 33. In this embodiment, four latching protrusions 200 are evenly distributed on the upper outer circumference of the cylindrical section 20, and four corresponding latching grooves 330 are evenly distributed on the peripheral wall 33.

[0043] A portion of the peripheral wall 33 protrudes in a direction away from the outer peripheral surface of the cylindrical part 20, forming a raised portion 331. The cup body 2 also has a mounting protrusion 201 protruding from the outer peripheral surface of the cylindrical part 20. The mounting protrusion 201 can be inserted upward from the lower end of the raised portion 331 into the mounting protrusion 201. The raised portion 331 and the mounting protrusion 201 facilitate faster alignment of the cylindrical part 20 and the upper cover 3 during assembly, and can guide the cylindrical part 20 and the upper cover 3 to be assembled more quickly and accurately.

[0044] The top cover 3 is also provided with an annular rib 34 that is integrally connected to the base plate 31. The peripheral wall 33 is fitted onto the upper end of the cup body 2. The annular rib 34 is located inside the cyclone separator 10. The upper end of the cup body 2 is embedded between the annular rib 34 and the peripheral wall 33. The inner peripheral surface of the peripheral wall 33 is against the outer peripheral surface of the cup body 2, and the outer peripheral surface of the annular rib 34 is against the inner peripheral surface of the cup body 2. This design enhances the tightness of the fit between the upper end of the cup body 2 and the top cover 3.

[0045] The upper cover 3 is also provided with a first flexible sealing gasket 35. The annular rib 34 is located inside the cyclone separator 10. The first flexible sealing gasket 35 is attached to the substrate 31. The first flexible sealing gasket 35 is located between the annular rib 34 and the peripheral wall 33, and can be stably held in the upper cover 3. The upper end of the cup body 2 abuts against the first flexible sealing gasket 35. The sealing between the upper end of the cup body 2 and the upper cover 3 is effectively achieved by means of the first flexible sealing gasket 35.

[0046] The garbage collector also includes a garbage bin, which includes a bin body 11 and a detachable lid 4 mounted on the upper part of the bin body 11. A cyclone separator 10 is mounted and fixed to the lid 4, so that the cyclone separator 10 stands upright on the lid 4. The interior of the cyclone separator 10 is connected to the interior of the garbage bin. Garbage separated from the cyclone airflow falls into the garbage bin through the cyclone separator 10. The lower end of the cup body 2 forms a support end for supporting the upright position of the cup body 2, and the cyclone separator 10 stands upright on the lid 4.

[0047] The garbage collector also includes screws 12 for locking the lid 4 to the cyclone separator 10. The lower end of the cyclone separator 10 is provided with a first annular wall 102, a locking screw portion 103 extending upward from the first annular wall 102, and a locking screw hole 104 that passes through the first annular wall 102 and extends upward into the locking screw portion 103. The first annular wall 102 surrounds the central axis A of the cyclone separator 10. The locking screw portion 103 and the first annular wall 102 are located outside the conical cylinder portion 21 of the cyclone separator 10 and are integrally connected to the conical cylinder portion 21. The screw 12 enters the locking screw hole 104 from the lower end of the locking screw hole 104. The locking screw portion 103 closes the upper end of the locking screw hole 104, so that the upper end of the screw 12 locked in the locking screw hole 104 is completely located within the locking screw portion 103. With this design, the locking screw portion 103 and the first annular wall 102 can be stably held together with the conical cylinder portion 21 of the cyclone separator 10, which facilitates a more stable locking of the cyclone separator 10 onto the bucket lid 4. The locking screw portion 103 of this application can prevent the upper end of the screw 12 from being exposed and causing injury. When the cyclone separator 10 of this application is not locked to the bucket lid 4 of this application, but to another bucket lid 4, and the locking screw portion 103 and the first annular wall 102 are basically exposed on the upper side of the other bucket lid 4, there will be no situation where a person touches the upper end of the screw 12 and is scratched. The cyclone separator 10 is made of plastic material, and the locking screw portion 103 is also provided with an anti-deformation hole extending into the locking screw portion 103. The anti-deformation hole is used to suppress the shrinkage deformation of the locking screw portion 103 during injection molding. The central axis A of the cyclone separator 10 is also the central axis of the conical section 21; in this application, the central axis A is a vertical straight line, and the central axis of the conical section 21 and the central axis of the cyclone tube section 30 are both central axis A.

[0048] The bin lid 4 has a recessed portion 40, into which the lower end of the cyclone separator 10 is accommodated. The recessed portion 40 has a base plate 400, which surrounds the central axis A of the cyclone separator 10 in a ring shape. The lower end of the cyclone separator 10 is supported downwards by the base plate 400. This arrangement allows the cyclone separator 10 to stand more stably on the bin lid 4. The base plate 400 is suspended below the recessed portion 40. The interior of the cyclone separator 10 is connected to the interior of the trash can. The interior of the trash can, except for its connection to the interior of the cyclone separator 10, is closed to the outside. The interior space of the trash can connects to the lower end of the cyclone separator 10 via the lower end of the recessed portion 40, thus connecting to the interior space of the cyclone separator 10. To enhance the strength of the base plate 400, several reinforcing ribs are provided on the ground of the base plate 400, and the reinforcing ribs connect the inner and outer perimeters of the base plate 400.

[0049] The lower end of the cyclone separator 10 is provided with a second flexible sealing washer 101 and a first annular wall 102 corresponding to the base plate 400. The first annular wall 102 and the second flexible sealing washer 101 surround the central axis A of the cyclone separator 10. The second flexible sealing washer 101 is attached to the lower surface of the first annular wall 102. Screws 12 pass through the base plate 400, the first annular wall 102, and the second flexible sealing washer 101, and the second flexible sealing washer 101 is pressed between the first annular wall 102 and the base plate 400. This design facilitates the stable support of the cyclone separator 10 by the first annular wall 102 and the base plate 400, and the second flexible sealing washer 101 prevents outside air from entering between the first annular wall 102 and the base plate 400. The second flexible sealing washer 101 is attached to the lower surface of the first annular wall 102 with adhesive. The second flexible sealing washer 101 has several through holes for the corresponding screws 12 to pass through.

[0050] The cyclone separator 10 is also provided with a second annular wall 105, which surrounds and is integrally connected to the conical cylindrical portion 21 of the cyclone separator 10, and is supported on the upper end of the recess 40. The upper end of the recess 40 and the bottom plate 400 form a double support for the cyclone separator 10 at different heights with the help of the first annular wall 102 and the second annular wall 105, so that the cyclone separator 10 can be placed more stably on the barrel cover 4.

[0051] The recess 40 is provided with a circumferential cylindrical wall 401, which surrounds the lower end of the cyclone separator 10. The lower end of the circumferential cylindrical wall 401 is integrally connected to the base plate 400, and the second annular wall 105 is supported on the upper end of the circumferential cylindrical wall 401. This arrangement can more stably support the cyclone separator 10.

[0052] The second annular wall 105 is located above the first annular wall 102 and has a larger inner diameter than the first annular wall 102. The cyclone separator 10 is also provided with a reinforcing rib 106. The conical cylinder portion 21 and the second annular wall 105 are integrally connected to the reinforcing rib 106. The reinforcing rib 106 extends downward from the second annular wall 105 to the corresponding locking screw portion 103 and is integrally connected to the corresponding locking screw portion 103. The upper end of the circumferential cylinder wall 401 is provided with a foolproof groove 402, and the reinforcing rib 106 is embedded in the foolproof groove 402. The reinforcing rib 106 can both cooperate with the foolproof groove 402 to prevent the cyclone separator 10 from being installed incorrectly (the installation angle is prone to deviation and inaccuracy) and connect the first annular wall 102 and the second annular wall 105 with the corresponding locking screw portion 103, thereby improving the structural stability of the first annular wall 102 and the second annular wall 105, and thus providing more stable support for the cyclone separator 10. The second annular wall 105 is vertically opposite to the first annular wall 102. The reinforcing rib 106 corresponds one-to-one with the anti-mistake groove 402, and there are two of each.

[0053] The lid 4 is also provided with a first protrusion 41 and a recess 40 that is recessed from the top of the first protrusion 41. During use, garbage will gradually accumulate inside the bin 11. Once the garbage accumulates to the lower end of the cyclone separator 10, the lid 4 needs to be opened to empty the bin 11. Otherwise, the cyclone separation effect on the garbage will be affected. The recess 40 is provided on the basis of the first protrusion 41 to help raise the cyclone separator 10 and delay the accumulation of garbage to the lower end of the cyclone separator 10.

[0054] The top surface 1050 of the second annular wall 105 and the top end 410 of the first protrusion 41 respectively surround the cyclone separator 10. The top surface 1050 of the second annular wall 105 is flush with the top end 410 of the first protrusion 41. The second annular wall 105 completely covers the first annular wall, the screw part, and the reinforcing rib 106. With this design, when viewed from the outside of the garbage collector, the cyclone separator 10 and the lid 4 are very simply combined, and no trace of the screw 12 locking can be seen.

[0055] The bottom plate 400 does not extend downward beyond the first protrusion 41, and the bottom plate 400 is completely located inside the first protrusion 41. The lower end of the recess 40 is suspended above the bin body 11, and the bottom plate 400 is located above the upper end of the bin body 11. This design ensures that even if the bin body 11 is full of garbage, it will not accumulate to the lower end of the cyclone separator 10, which helps to reduce the frequency of emptying the garbage bin.

[0056] The waste collector also includes a hose 13. The lid 4 is provided with two accessory receiving slots 42 located on opposite sides of the first protrusion 41. A recess 40 is recessed from the first protrusion 41, and a portion of the cyclone separator 10 is accommodated in the recess 40. The first protrusion 41 is provided with two side walls 411 corresponding to the two accessory receiving slots 42. One side wall 411 forms part of the groove wall of the corresponding accessory receiving slot 42, and the other side wall 411 forms part of the groove wall of the corresponding accessory receiving slot 42. The hose 13 can be coiled and stored along the two accessory receiving slots 42 to achieve orderly storage of the hose 13. The air inlet 100 is approximately parallel to the accessory receiving slots 42.

[0057] The lid 4 also includes an annular baffle 43, two elongated connecting walls 44, and several reinforcing ribs 45. The connecting walls 44 are located below the corresponding side walls 411 and are integrally connected to them. The opposite ends of the connecting walls 44 are connected to the annular baffle 43, and the reinforcing ribs 45 connect the annular baffle 43 and the connecting walls 44. This design enhances the stability of the lid 4 and its first protrusion 41. The side walls 411 extend upward from the bottom wall 420 of the accessory receiving groove 42, and the connecting walls 44 extend downward from the bottom wall 420 of the accessory receiving groove 42.

[0058] The lid 4 also has two second protrusions 46 located on opposite sides of the first protrusion 41. One accessory receiving groove 42 is formed by the gap between the first protrusion 41 and one of the second protrusions 46, and the other accessory receiving groove 42 is formed by the gap between the first protrusion 41 and the other of the second protrusions 46. The two second protrusions 46 are secured to the sides of the lid 4 with screws.

[0062] This waste collector can be used with a vacuum cleaner to collect debris and other waste generated during the operation of power tools (such as polishers, planers, etc.). In use, a pipe (such as hose 13) connects the waste outlet of the power tool to the air inlet 100 of the cyclone separator 10. Another pipe (such as hose) connects the vacuum cleaner's suction inlet to the air outlet 32 ​​of the cyclone separator 10. Under the suction of the vacuum cleaner, the waste generated by the power tool enters the cyclone separator 10 through the pipe and air inlet 100. The waste, accompanied by the suction airflow, rotates around the cyclone tube section 30 within the cyclone separator 10. Under centrifugal force, the waste separates from the cyclone airflow and gradually slides down the inner wall of the cup 2 into the waste bin. The airflow (which still carries a small amount of dust and fine debris, as these are difficult to separate from the cyclone) enters the vacuum cleaner through the cyclone tube section 30, air outlet 32, and pipe, and is then filtered by the vacuum cleaner's filter before being discharged into the atmosphere. The cyclone separator 10 can be made of transparent material to allow observation of the garbage's rotation with the cyclone and its sliding. Wheels 15 are provided at the bottom of the garbage bin for easy movement of the garbage collector.
