Description

Technical Field

[0001] This utility model belongs to the field of dustbin technology, and particularly relates to a cyclone device and a dustbin. Background Technology

[0002] Dust collection equipment typically includes a cyclone structure and a dust collection bin. The cyclone structure draws in external dust and other pollutants, separating them from the air. The dust falls into the dust collection bin, while the air is expelled to the outside. For example, Chinese patent CN210814482U discloses a double-layer cyclone dust collection device. This device mainly includes a top cover, a filter element, an outer bin, a dust collection bin, and an inner baffle. The filter element is located inside the outer bin, which has an air inlet on its wall. The bottom of the outer bin connects to an integrated bin via a dust outlet. When dust-laden air enters the outer bin through the air inlet, it collides directly with the inner baffle, creating a cyclone that separates the dust and air. A large amount of dust falls into the dust collection bin through the dust outlet at the bottom of the outer bin, while the separated air is filtered by the filter element inside the dust collection bin before being discharged to the outside. In this type of dust collection device, dust tends to accumulate on the inner baffle and the outer barrel wall during the dust collection process, making it difficult to clean. Furthermore, the dust is slowly ejected from the outer barrel, and it tends to accumulate at the dust outlet of the outer barrel or float on the top of the dust collection barrel, making it difficult to fall to the bottom of the barrel quickly. As a result, the dust collection efficiency is not high. Utility Model Content

[0003] To address the aforementioned technical problems in the existing technology, this utility model provides a cyclone device and a dust collection bin. This cyclone device has high dust collection efficiency and is less prone to dust accumulation.

[0004] The technical solution adopted in this embodiment of the utility model is:

[0005] A cyclone device for use inside a dust collection bin, the dust collection bin having a cavity for holding garbage, the cyclone device comprising:

[0006] A cyclone shell has a receiving cavity, and the cyclone shell is provided with a shell dust inlet, a shell dust outlet, a shell air inlet, and a shell air outlet communicating with the receiving cavity; the shell dust inlet and the shell air outlet are used to communicate with the outside respectively; the shell dust outlet and the shell air inlet are used to communicate with the barrel cavity respectively;

[0007] A cyclone assembly is disposed within the receiving cavity. The cyclone assembly includes a central column and a first spiral blade and a second spiral blade disposed on the central column. The two spiral blades, the outer peripheral wall of the central column, and the cavity wall of the receiving cavity together define a spiral channel independent of the receiving cavity. The inlet of the spiral channel is connected to the dust inlet of the housing, and the outlet of the spiral channel is connected to the dust outlet of the housing.

[0008] A filter element, disposed within the receiving cavity, is used to filter the airflow entering the receiving cavity through the air inlet of the housing.

[0009] Furthermore, the receiving cavity includes a first cavity and a second cavity that are not interconnected. The dust inlet and dust outlet of the housing are respectively connected to the first cavity, and the air inlet and air outlet of the housing are respectively connected to the second cavity. The cyclone assembly is disposed in the first cavity, and the filter element is disposed in the second cavity. The two cavities are not interconnected, so that the dust collection process and the air exhaust process of the cyclone device do not affect each other.

[0010] Furthermore, the central column is a hollow column, and the hollow portion of the central column forms a core cavity. The filter element extends into the core cavity, and a portion of the outer peripheral wall of the cyclone shell protrudes outward to form a dust outlet cavity communicating with the receiving cavity. A notch is provided on the outer peripheral wall of the central column, allowing the airflow filtered by the filter element to enter the dust outlet cavity through the notch and then be discharged through the air outlet of the shell. By placing the filter element within the core cavity and providing a notch on the outer peripheral wall of the hollow column to communicate with the dust outlet cavity, this structure is more compact and reduces the space occupied by the cyclone assembly and filter element within the receiving cavity.

[0011] Furthermore, the bottom of the cyclone shell is open to form a dust outlet, through which the cyclone assembly can extend into the receiving cavity. The cyclone assembly is provided with a connecting post, which has a first connecting hole. The top wall of the receiving cavity has a second connecting hole. Bolts passing through the first and second connecting holes can fix the cyclone assembly inside the receiving cavity. This structure facilitates the simultaneous installation of the cyclone assembly and the filter element within the receiving cavity.

[0012] Furthermore, the dust inlet and air outlet of the casing are respectively located on the side wall of the cyclone casing, the air inlet is located on the top wall of the cyclone casing, and the dust outlet is located on the bottom wall of the cyclone casing. The dust outlet being located on the bottom wall of the cyclone casing allows dust or debris to quickly fall to the bottom of the container cavity, while the air inlet being located on the top wall of the cyclone casing prevents dust or debris from being sucked into the receiving cavity.

[0013] Furthermore, the filter element includes a columnar core and an upper core cover and a lower core cover connected to both ends of the core. The axis of the core is parallel to the axis of the central column, and the upper core cover is provided with a core cover air inlet for communicating with the air inlet of the housing.

[0014] A dust collection bin includes a bin body, the bin body including a cavity for holding garbage, and the dust collection bin includes a cyclone device as described in any of the above embodiments, the cyclone device being disposed inside the dust collection bin and outside the cavity.

[0015] Furthermore, the dust collection bin also includes a dust inlet channel, an air outlet channel, and an exhaust device. The bottom wall of the bin body is provided with a dust inlet, and the side wall of the bin body is provided with an air outlet. The dust inlet channel connects the dust inlet of the bin body and the dust inlet of the shell. The inlet of the air outlet channel is connected to the air outlet of the shell, the outlet of the air outlet channel is connected to the air inlet of the exhaust device, and the air outlet of the exhaust device is connected to the air outlet of the bin body.

[0016] Furthermore, the barrel body also includes a lower barrel body and an upper barrel body fastened to the lower barrel body. The lower barrel body includes an outer barrel body and an inner barrel body disposed within the outer barrel body. The interior of the inner barrel body forms the barrel cavity, and the outer peripheral wall of the outer barrel body forms the outer peripheral wall of the barrel body. A partition cavity is defined between the outer peripheral wall of the inner barrel body and the inner peripheral wall of the outer barrel body. The dust inlet channel, the air outlet channel, and the exhaust device are disposed within the partition cavity. The dust inlet channel, the air outlet channel, and the exhaust device are all disposed within the partition cavity to avoid occupying the internal space of the barrel cavity.

[0017] Furthermore, the exhaust device is located below the inner barrel, the air inlet channel and the air outlet channel are respectively located on one side of the inner barrel along the direction perpendicular to its axis, and the cyclone device is located in the upper barrel and above the barrel cavity. This can make reasonable use of the space inside the dust collection bucket and make its internal structure compact.

[0018] Compared with the prior art, the beneficial effects of the embodiments of this utility model are as follows:

[0019] The cyclone device provided by this utility model defines a spiral channel by two spiral blades, the outer peripheral wall of the central column, and the cavity wall of the receiving chamber. The spiral channel connects the dust inlet and the dust outlet of the housing. The spiral channel accelerates the flow of dust-laden air, causing the dust to quickly fall to the bottom of the chamber and preventing dust accumulation. Furthermore, the spiral channel is independent of the receiving chamber, ensuring that dust collection and exhaust processes are independent and do not interfere with each other.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the technical solutions of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] This utility model embodiment provides a cyclone device for use inside a dust collection bin. The dust collection bin has a cavity 42 for holding dust or garbage. The cyclone device can draw outside air into the cavity 42. As the outside air enters the cavity 42, it carries dust or garbage from the ground into the cavity 42, where the dust and other debris fall into the cavity 42. The air that has entered the cavity 42 is then discharged to the outside through the cyclone device.

[0037] like Figure 1 and Figure 5 As shown, the cyclone device in this embodiment mainly includes a cyclone shell 1, a cyclone assembly 2, and a filter element 3.

[0038] The cyclone shell 1 has a receiving cavity, and the cyclone shell 1 is provided with a shell dust inlet 10, a shell dust outlet 11, a shell air inlet 12, and a shell air outlet 13 that communicate with the receiving cavity. Among them, the shell dust inlet 10 and the shell air outlet 13 are used to communicate with the outside world, and the shell dust outlet 11 and the shell air inlet 12 are used to communicate with the barrel cavity 42, respectively.

[0039] Cyclone assembly 2 is disposed within the receiving cavity. Cyclone assembly 2 includes a central column 20 and a first helical blade 21 and a second helical blade 22 disposed on the central column 20. The two helical blades have the same diameter, and the first helical blade 21 is located above the second helical blade 22.

[0040] like Figure 1 and Figure 5As shown, the two spiral blades, together with the outer peripheral wall of the central column 20 and the cavity wall of the receiving cavity, define a spiral channel independent of the receiving cavity. The inlet of the spiral channel is connected to the dust inlet 10 of the housing, and the outlet of the spiral channel is connected to the dust outlet 11 of the housing. Air carrying dust can quickly enter the bucket cavity 42 after being accelerated and changed direction through the spiral channel, thereby realizing the dust collection function of the dust collection bucket.

[0041] The filter element 3 is located inside the receiving cavity. The air inside the chamber 42 enters the filter element 3 inside the receiving cavity through the air inlet 12 of the housing for filtration and is finally discharged to the outside, so as to avoid the air pollution caused by the gas discharged through the air outlet 13 of the housing, thereby realizing the function of filtering air in the dust collection bin.

[0042] In the cyclone device provided in this embodiment, the two spiral blades, the outer peripheral wall of the central column 20, and the cavity wall of the receiving cavity together define a spiral channel, which connects the dust inlet 10 and the dust outlet 11 of the housing. The spiral channel can accelerate the flow of air carrying dust, allowing the dust to fall quickly into the bottom of the chamber 42, and it is not easy for dust to accumulate. At the same time, the spiral channel is independent of the receiving cavity, and the dust collection and exhaust processes are independent of each other and do not affect each other.

[0043] like Figure 4 As shown, in some embodiments, the receiving cavity within the cyclone shell 1 includes a first cavity 14 and a second cavity 15 that are not interconnected. The cyclone assembly 2 is disposed within the first cavity 14, and the filter element 3 is disposed within the second cavity 15.

[0044] The dust inlet 10 and dust outlet 11 on the cyclone shell 1 are respectively connected to the first cavity 14, and the air inlet 12 and air outlet 13 on the cyclone shell 1 are respectively connected to the second cavity 15.

[0045] The two spiral blades in the cyclone assembly 2, together with the outer peripheral wall of the central column 20 and the cavity wall of the first cavity 14, define a spiral channel. Outside air carrying dust enters the barrel cavity 42 through this spiral channel. The air inside the barrel cavity 42 is filtered by the filter element 3 before entering the second cavity 15, and then discharged through the housing outlet 13. In this embodiment, the cyclone assembly 2 and the filter element 3 are each housed in a separate cavity, operating independently.

[0046] like Figure 5 and Figure 8 As shown, in some embodiments, the central column 20 in the cyclone assembly 2 is a hollow column, and the hollow portion of the central column 20 forms a core cavity, into which the filter element 3 can extend and be fixed. This structure integrates the cyclone assembly 2 and the filter element 3 together, resulting in a more compact structure and reducing the space they occupy in the receiving cavity.

[0047] Furthermore, part of the outer peripheral wall of the cyclone shell 1 protrudes outward to form a dust outlet chamber 16 that communicates with the receiving cavity. The outer peripheral wall of the central column 20 is provided with a notch 17 that communicates with the receiving cavity. The air in the barrel cavity 42 can enter the dust outlet chamber 16 through the notch 17 after being filtered by the filter element 3, and then be discharged through the air outlet 13 of the shell.

[0048] The notch 17 on the center column 20 is located at its top, and the bottom of the center column 20 is sealed, so that the filter element 3 can be placed directly into the core cavity through the notch 17 at the top of the center column 20. The core cavity can be used to fix the filter element 3.

[0049] Furthermore, such as Figure 8 As shown, in some embodiments, the bottom of the cyclone shell 1 is open and forms the shell dust outlet 11 of the cyclone shell 1. The cyclone assembly 2 as a whole can extend into and be fixed in the receiving cavity from the shell dust outlet 11, and the outlet of the spiral channel is opposite to the shell dust outlet 11. This structure facilitates the installation of the cyclone assembly 2 into the receiving cavity.

[0050] Preferably, such as Figure 5 As shown, in this embodiment, the upper surface of the starting end of the first spiral blade 21 of the cyclone assembly 2 is provided with a vertically arranged connecting post 23, and the free end of the connecting post 23 is provided with a first threaded hole. The top wall of the receiving cavity is provided with a second threaded hole. When the cyclone assembly 2 is placed in the receiving cavity, the first threaded hole of the connecting post 23 and the second threaded hole on the top wall of the receiving cavity are opposite each other. At this time, the cyclone assembly 2 can be fixed in the receiving cavity by screwing the bolts into the first threaded hole and the second threaded hole in sequence. This connection structure is simple and convenient for installing the cyclone assembly 2 and the filter element 3.

[0051] In this embodiment, the cyclone assembly 2 is suitable for placement at the top of the dustbin cavity 42. Dust or debris sucked up by the cyclone device will automatically fall into the cavity 42 under its own gravity. Preferably, as shown... Figure 2 and Figure 3 as well as Figure 6 and Figure 7 As shown, the air inlet 12 of the casing is located on the top wall of the cyclone casing 1, and the dust outlet 11 of the casing is located on the bottom wall of the cyclone casing 1. In this way, after dust or garbage is discharged from the dust outlet 11 of the casing, it can quickly fall into the bottom of the barrel cavity 42. At the same time, placing the air inlet 12 of the casing on the top wall of the cyclone casing 1 can prevent garbage and dust in the barrel cavity 42 from being sucked into the receiving cavity, so as to ensure that the dust suction process and the air exhaust process of the cyclone device do not affect each other.

[0052] As for the dust inlet 10 and the air outlet 13 of the casing, they can be respectively located on the outer peripheral wall of the cyclone casing 1.

[0053] like Figure 1 and Figure 5As shown, in some embodiments, the filter element 3 includes a columnar core 30 and an upper core cover 31 and a lower core cover 32 connected to both ends of the core 30. The upper core cover 31 and the lower core cover 32 have the same outer diameter. The outer diameter of the core 30 is smaller than the outer diameter of the upper core cover 31, and the outer diameter of the upper core cover 31 is smaller than the diameter of the air inlet 12 of the housing. The filter element 3 can directly pass through the air inlet 12 of the housing and extend into the second cavity 15 inside the cyclone shell 1 or into the core cavity of the central column 20, thereby facilitating the installation of the filter element 3.

[0054] Furthermore, in this embodiment, both the core 30 and the central column 20 are vertically arranged within the receiving cavity. The upper core cover 31 is provided with a core cover air inlet for communicating with the housing air inlet 12, so that the gas entering the receiving cavity through the housing air inlet 12 can directly enter the core 30 for filtration.

[0055] This utility model embodiment also provides a dust collection bucket, such as Figures 9 to 12 As shown, the dustbin includes a body 4, which includes a cavity 42 for holding dust or garbage. The dustbin also includes a cyclone device as described in any of the above embodiments.

[0056] The cyclone device is located inside the body 4 of the dust collection bin and outside the bin cavity 42, so that the bin cavity 42 has enough space to hold dust or garbage. At the same time, the cyclone device is located above the bin cavity 42, and the dust sucked in by the cyclone device will automatically fall to the bottom of the bin cavity 42 under the action of gravity.

[0057] like Figure 10 , Figure 11 as well as Figure 12 As shown, in some embodiments, the outer peripheral wall of the dust collection bin is provided with a dust inlet 43 and a dust outlet 44. The dust collection bin also includes a dust inlet channel 5, a dust outlet channel 6, and an exhaust device 7. The dust inlet channel 5 is used to connect the dust inlet 10 of the shell and the dust inlet 43 of the bin, so that air carrying dust from the outside can enter the bin cavity 42 through the dust inlet channel 5.

[0058] The inlet of the air outlet 6 is connected to the air outlet 13 of the housing, the outlet of the air outlet 6 is connected to the air inlet of the exhaust device 7, and the air outlet of the exhaust device 7 is connected to the air outlet 44 of the barrel. By activating the exhaust device, external dust can be sucked into the dust collection barrel through the cyclone device, and the air in the dust collection barrel can be filtered by the cyclone device and discharged to the outside of the dust collection barrel.

[0059] Preferably, the dust inlet 43 is located on the bottom wall of the dust collection bin. Users can sweep dust and other garbage on the ground to the vicinity of the dust inlet 43 and then start the exhaust device 7 to suck the dust and other garbage on the ground into the bin cavity 42, thereby improving the convenience of dust collection in the dust collection bin.

[0060] Meanwhile, the air outlet 44 is located on the side wall of the dust collection bin, so the airflow discharged through the dust collection bin will not blow directly to the ground, thus ensuring that the dust collection bin will not affect dust collection during the exhaust process.

[0061] like Figure 10 As shown, in some embodiments, the bucket body 4 further includes a lower bucket body 41 and an upper bucket body 40 fastened to the lower bucket body 41. The lower bucket body 41 includes an outer bucket body 410 and an inner bucket body 411 disposed within the outer bucket body 410. The outer peripheral wall of the outer bucket body 410 forms the outer peripheral wall of the dust collection bucket, and the interior of the inner bucket body 411 forms a bucket cavity 42.

[0062] A partition cavity is formed between the outer peripheral wall of the inner barrel 411 and the inner peripheral wall of the outer barrel 410. The dust inlet channel 5, the air outlet channel 6, and the exhaust device 7 are all located in the partition cavity to avoid occupying the internal space of the barrel cavity 42.

[0063] In some embodiments, the cyclone device is located inside the upper barrel 40 and above the inner barrel 411. External dust collected by the cyclone device can be accelerated through the spiral channel and quickly fall into the bottom of the barrel cavity 42, avoiding the problem of dust accumulating at the barrel opening.

[0064] The exhaust device is located below the inner barrel 411 in the partition chamber. The dust inlet channel 5 and the air outlet channel 6 are located on one side of the inner barrel 411 along the direction perpendicular to its axis, which can make reasonable use of the space inside the dust collection bucket and make its internal structure compact.

[0065] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
