Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning equipment technology, and in particular to a dust collection device and a vacuum cleaner. Background Technology
[0002] Vacuum cleaners generally consist of a main unit, an airflow generator, a cyclone separator, and a dust cup. The airflow generator draws in outside dust and air into the main unit. After being filtered and separated by the cyclone separator, the dust and debris are collected in the dust cup, while relatively clean air is discharged from the main unit. After the vacuum cleaner finishes its work, the dust cup needs to be emptied promptly to prevent excessive dust buildup and maintain cleaning performance. Furthermore, because the cyclone separator has a filter that prevents dust from being expelled with the airflow from the main unit, some dust accumulates on the filter after use. Therefore, cleaning the dust cup requires detaching the cyclone separator from the dust cup to clean the filter, making the cleaning process cumbersome and inefficient, which no longer meets current market demands.
[0003] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention
[0004] The purpose of this invention is to provide a dust collection device and a vacuum cleaner that can simultaneously clean the dust in the dust cup and scrape dust from the cyclone separator.
[0005] The objective of this invention is achieved through the following technical solution: a dust collection device, comprising:
[0006] A dust cup includes a dust cup body with a dust outlet and a dust cup cover movably connected to the dust cup body for opening and closing the dust outlet;
[0007] A cyclone separator includes a base fixedly connected to the dust cup body and a separator body movably connected to the base. The separator body has a working state and a dust-scraping state. The base is adapted to scrape dust from the separator body when the separator body switches between states.
[0008] The telescopic mechanism is connected to the separator body and has an extended state and a retracted state. The telescopic mechanism switches from the retracted state to the extended state in response to the opening of the dust cup cover, and drives the separator body to switch from the working state to the dust scraping state in response to the closing of the dust cup cover.
[0009] When the separator body is in the ash-scraping state, the base is adapted to reset the separator body from the ash-scraping state to the working state, and to switch the telescopic mechanism from the extended state to the retracted state.
[0010] Furthermore, the base includes:
[0011] The guide tube is movably connected to the separator body and can guide the separator body to move to the working state or the ash-scraping state;
[0012] A scraper is fixedly connected to the guide cylinder. The scraper surrounds the scraping part of the separator body and is used to scrape the scraping part.
[0013] The base body is fixedly connected to the guide cylinder; and
[0014] A first elastic element is mounted on the base and provides a force to drive the separator body back from the scraping state to the working state.
[0015] Furthermore, the base is detachably connected to the dust cup body.
[0016] Furthermore, the separator body includes:
[0017] The housing is coaxially arranged with the guide cylinder, and a filter screen is provided around the outer periphery of the housing. The scraper is made of flexible material and surrounds the outer periphery of the filter screen.
[0018] The second mounting component is fixedly connected to the housing and can be moved along the axial direction of the guide tube and pass through the guide tube.
[0019] A receiving frame is fixed inside the housing, and the first elastic member abuts between the base and the receiving frame;
[0020] The telescopic mechanism is telescopically disposed within the housing along the axial direction of the guide cylinder.
[0021] Furthermore, the telescopic mechanism includes:
[0022] The guide sleeve is fixedly connected to the separator body;
[0023] The push rod is movably inserted into the guide sleeve;
[0024] The second elastic element abuts between the guide sleeve and the push rod, and provides a force to drive the push rod out of the ash discharge port; and
[0025] A latch is movably connected to the guide sleeve and adapted to lock the push rod when the push rod is in the extended state and to unlock it when the separator body is in the scraping state;
[0026] The dust cup cover is adapted to push the push rod to move along the contraction direction when switching from the open state to the closed state, and drive the separator body to switch to the dust scraping state.
[0027] Furthermore, the side of the dust cup cover facing the push rod is at least partially an inwardly concave arc surface, and the end of the push rod that contacts the arc surface is a hemispherical structure.
[0028] Furthermore, the latch is hinged to the guide sleeve and can be rotated to a locked state or an unlocked state. The latch is provided with a third elastic element that drives the latch to remain in the locked state, and the push rod is provided with a locking groove that matches the latch.
[0029] Furthermore, the latch is disposed opposite to the seat, and when the separator body moves to the scraping state, the seat can push the latch to gradually disengage from the locking groove.
[0030] Furthermore, the rebound force of the first elastic element is greater than that of the second elastic element.
[0031] In addition, the present invention also provides a vacuum cleaner, including the aforementioned dust collection device;
[0032] The vacuum cleaner main unit is detachably connected to the dust collection device.
[0033] Compared with the prior art, the present invention has the following beneficial effects: When cleaning the dust collection device, the dust collected in the dust cup can be emptied by opening the dust cup cover. When the dust cup cover is closed, the telescopic mechanism responds to the above-mentioned switch action and drives the separator body to move relative to the base, so that the base can perform a dust scraping operation on the separator body, avoiding the user from performing additional dust scraping operations on the separator body. The operation is simple and efficient, effectively improving the user experience. In addition, since the dust scraping operation can easily cause dust to fly around, in the present invention, the base performs the dust scraping operation when the dust cup cover is turned to the closed state. The scraped dust is less likely to fly out of the dust cup body and be inhaled by the human body, improving safety and the cleanliness of the area around the dust collection device.

Detailed Implementation
[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, it should be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings, not the entire structure. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.
[0048] The terms “comprising” and “having”, and any variations thereof, used in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.
[0049] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0050] Please see Figure 1 As shown, a dust collection device corresponding to a preferred embodiment of the present invention includes a dust cup 100 and a cyclone separator 200 located inside the dust cup 100. The dust cup 100 can receive dust from the outside, and the cyclone separator 200 can perform gas-solid separation on the dust so that relatively clean air is discharged from the dust cup 100.
[0051] Furthermore, the dust cup 100 includes a dust cup body 110 and a dust cup cover 120 movably connected to the dust cup body 110. The dust cup body 110 is generally cylindrical, and a dust chamber 111 is formed inside it. The dust chamber 111 has a through structure along the axial direction of the dust cup body 110, so that a dust discharge port 112 and an installation port 113 are formed at its two ends, respectively. The dust discharge port 112 is used to pour out dust, and the dust cup cover 120 is disposed at the dust discharge port 112 to open and close the dust discharge port 112. The cyclone separator 200 can be inserted into the dust chamber 111 through the installation port 113. An air inlet 114 is opened on the periphery of the dust cup body 110, and the air inlet 114 is connected to the dust chamber 111. External dust can enter the dust cup body 110 through the air inlet 114 and undergo gas-solid separation under the action of the cyclone separator 200, so that dust is collected in the dust cup body 110 and relatively clean air is discharged from the outlet of the cyclone separator 200.
[0052] Furthermore, the dust cup cover 120 is a circular cover plate adapted to the ash discharge port 112. In this embodiment, for ease of operation, the dust cup cover 120 is hinged to the dust cup body 110. The dust cup cover 120 can be rotated to the end of the dust cup body 110 to cover the ash discharge port 112, or the dust cup cover 120 can be rotated away from the end of the dust cup body 110 to open the ash discharge port 112. A snap-fit structure can be provided between the dust cup cover 120 and the dust cup body 110 to ensure a reliable connection between the dust cup cover 120 and the dust cup body 110 after the dust cup cover 120 is placed on the ash discharge port 112, preventing leakage from the ash discharge port 112 due to loosening.
[0053] Furthermore, combined Figure 2 and Figure 3 As shown, the cyclone separator 200 includes a base 210 and a separator body 220. The base 210 is detachably fixedly connected to the dust cup body 110, and the separator body 220 is movably connected to the base 210. The separator body 220 has a working state and a dust scraping state. The working state is the state in which the cyclone separator 200 performs normal cyclone separation. The base 210 is adapted to scrape dust from the separator body 220 when the state of the separator body 220 is switched.
[0054] The dust collection device also includes a telescopic mechanism 300 connected to the separator body 220. The telescopic mechanism 300 has an extended state extending out of the ash discharge port 112 and a retracted state retracted into the ash discharge port 112. The telescopic mechanism 300 switches from the retracted state to the extended state in response to the opening of the dust cup cover 120, and drives the separator body 220 from the working state to the ash scraping state in response to the closing of the dust cup cover 120. In addition, when the separator body 220 is in the ash scraping state, the base 210 is adapted to reset the separator body 220 from the ash scraping state to the working state, and to switch the telescopic mechanism 300 from the extended state to the retracted state.
[0055] By employing the above-described structure, when the dust collection device needs cleaning, the dust cup cover 120 is opened, allowing the dust collected in the dust cup body 110 to be emptied. When the dust cup cover 120 is closed, the telescopic mechanism 300 responds to the aforementioned switch action, driving the separator body 220 to move relative to the base 210. This allows the base 210 to perform a dust scraping operation on the separator body 220, avoiding the need for the user to perform additional dust scraping operations on the separator body 220. This makes the operation simple and efficient, effectively improving the user experience. Furthermore, since dust scraping operations can easily cause dust to fly around, in this invention, the base 210 performs the dust scraping operation when the dust cup cover 120 is turned to the closed state. The scraped dust is less likely to fly out of the dust cup body 110 or be inhaled by the human body, improving safety and the cleanliness around the dust collection device.
[0056] Furthermore, referring to Figure 1 , Figure 2 and Figure 4As shown, the base 210 includes a guide cylinder 211 coaxially arranged with the dust cup body 110, and the guide cylinder 211 has a through structure in the axial direction. The guide cylinder 211 is located near the mounting port 113, and a sealing ring 2111 is provided between the guide cylinder 211 and the inner wall of the dust chamber 111.
[0057] The separator body 220 can be inserted into the guide tube 211 from one end toward the ash discharge port 112, and can move along the axial direction of the guide tube 211 to switch between working state and ash scraping state. The base 210 also includes an ash scraper 212 disposed on the guide tube 211. The ash scraper 212 is an annular structure continuously distributed along the periphery of the separator body 220 and corresponds to the outer periphery of the ash scraping part of the separator body 220.
[0058] When the separator body 220 switches from the working state to the dust-scraping state, the separator body 220 gradually extends into the guide cylinder 211. At this time, the dust-scraping component 212 can gradually perform dust-scraping operations on the outer periphery of the dust-scraping part. In this embodiment, the dust-scraping component 212 can be made of flexible materials such as rubber sheets, silicone sheets, or brushes with a certain degree of elasticity. The inner diameter of the dust-scraping component 212 is smaller than the outer diameter of the dust-scraping part, so that it can fit tightly with the dust-scraping part under the rebound force, improving the cleaning effect of the dust-scraping part and making it less likely to damage the dust-scraping part. Of course, the dust-scraping component 212 can also be made of a hard sheet with high strength. The inner diameter of the dust-scraping component 212 is not smaller than the outer diameter of the dust-scraping part. The hard structure of the dust-scraping component 212 has a longer service life and is not easily deformed during the dust-scraping process.
[0059] Preferably, to improve the stability of the separator body 220 along the axial direction of the guide cylinder 211, a guide rail 2112 is protruding from the inner wall of the guide cylinder 211. The guide rail 2112 is preferably integrally formed with the guide cylinder 211 for easy assembly. The guide rail 2112 extends from one end of the guide cylinder 211 to the other along its axial direction. A guide groove 2222, which matches the guide rail 2112, is recessed inward on the outer circumference of the separator body 220 to guide the movement of the separator body 220 while preventing it from rotating around the axis of the base 210. In this embodiment, there are multiple guide rails 2112, evenly distributed along the circumference of the guide cylinder 211. Correspondingly, there are also multiple guide grooves 2222, each corresponding to one of the guide rails 2112.
[0060] In addition, the base 210 also includes a seat 213 fixedly connected to the guide tube 211. The seat 213 includes a first mounting member 214 and a mounting cylinder 215 fixed on the first mounting member 214. The first mounting member 214 covers the end of the guide tube 211 away from the ash discharge port 112. The mounting cylinder 215 is coaxially inserted in the guide tube 211 and is at least partially located inside the separator body 220. An exhaust port (not shown) communicating with the mounting cylinder 215 is provided on the first mounting member 214, and air inside the separator body 220 can be discharged through the mounting cylinder 215 and the exhaust port.
[0061] A first elastic element 216 is sleeved on the mounting cylinder 215, and the first elastic element 216 is limited between the separator body 220 and the first mounting member 214. The first elastic element 216 is specifically a spring. When the separator body 220 is pushed and switches to the dust scraping state, the first elastic element 216 will be compressed, and when the pushing force is removed, the first elastic element 216 can push the separator body 220 back to the working state.
[0062] Furthermore, referring to Figure 1 , Figure 2 and Figure 5 As shown, the separator body 220 includes a housing 221, a second mounting member 222, and a receiving frame 223. The housing 221 is coaxially arranged with the base 210 and has a through structure in the axial direction. A filter screen 224 for filtering dust is provided around the outer periphery of the housing 221, allowing air to enter the housing 221 through the filter screen 224. The second mounting member 222 is fixedly sealed at the end of the housing 221 away from the ash discharge port 112, and the outer periphery of the second mounting member 222 protrudes relative to the housing 221. A clearance hole 2221 is provided on the second mounting member 222, through which the mounting cylinder 215 extends into the housing 221 to communicate with the interior of the housing 221. The outer contour of the second mounting member 222 is adapted to the inner contour of the guide cylinder 211 to slide in the axial direction with the guide cylinder 211. The guide groove 2222 is formed by recessing inward from the outer edge of the second mounting member 222.
[0063] In this embodiment, the dust scraping part of the separator body 220 is specifically the filter screen 224. The filter screen 224 is in close contact with the dust scraper 212. When the second mounting part 222 moves axially along the guide tube 211, the dust scraper 212 can scrape and clean the surface of the filter screen 224.
[0064] The receiving frame 223 is fixed inside the housing 221 and contacts the end of the first elastic member 216 away from the first mounting member 214. When the separator body 220 is pushed and moves toward the dust scraping state, the first elastic member 216 is gradually compressed under the resistance of the first mounting member 214 and the receiving frame 223.
[0065] Furthermore, referring to Figure 1 , Figure 2, Figure 6 and Figure 7 As shown, the telescopic mechanism 300 is located at one end of the housing 221 near the ash discharge port 112. The telescopic mechanism 300 includes a mounting head 310, a guide sleeve 320, a push rod 330, a second elastic element 340, and a latch 350.
[0066] The mounting head 310 is detachably fixed to the end of the housing 221 near the ash outlet 112. The mounting head 310 and the housing 221 can be connected by a screw-on structure or by a threaded connector. In this embodiment, the screw-on structure is preferred, so that the mounting head 310 can be installed and removed without additional tools.
[0067] The mounting head 310 has a mounting hole 311 in the middle, and the guide sleeve 320 is fixedly inserted into the mounting hole 311 and housed in the housing 221. The guide sleeve 320 is coaxially arranged with the housing 221. The push rod 330 is movably inserted into the guide sleeve 320 along the axial direction and can extend to the outside through the mounting hole 311 and the ash discharge port 112. In order to improve the stability of the push rod 330 moving in the axial direction of the guide sleeve 320, a guide structure as described above between the second mounting member 222 and the guide cylinder 211 can also be provided on the periphery of the mounting hole 311.
[0068] The second elastic element 340 is specifically a spring, which rests between the guide sleeve 320 and the push rod 330, and provides a force to drive the push rod 330 out of the ash discharge port 112. The latch 350 is movably connected to the guide sleeve 320 and is adapted to lock the push rod 330 when it extends out of the ash discharge port 112, and to release the lock when the separator body 220 is in the ash scraping state.
[0069] Specifically, the side of the dust cup cover 120 facing the push rod 330 is at least partially an inwardly concave arc surface 121. When the dust cup cover 120 switches from the open state to the closed state, the arc surface 121 can contact the push rod 330 and guide the push rod 330 to move along the contraction direction (i.e., the axial direction). Preferably, in order to improve the reliability of the retraction of the push rod 330, the end of the push rod 330 that contacts the arc surface 121 has a hemispherical structure and is adapted to fit the arc surface 121, so that the arc surface 121 and the push rod 330 fit tightly together.
[0070] The latch 350 is hinged to the guide sleeve 320, and the rotation axis of the latch 350 is perpendicular to the axis of the guide sleeve 320. The latch 350 can rotate relative to the guide sleeve 320 to a locked or unlocked state. The push rod 330 has a recessed locking groove 331 on its circumference. When the latch 350 is in the locked state, the latch 350 is embedded in the locking groove 331, thereby restricting the axial movement of the push rod 330. When the latch 350 is in the unlocked state, the latch 350 disengages from the locking groove 331, and the push rod 330 can extend and retract normally.
[0071] The latch 350 includes a latch body 351, a first connecting part 352, and a second connecting part 353. The latch body 351 has a latch part 3511 corresponding to the push rod 330 at one end near the ash outlet 112, and the latch part 3511 is adapted to the locking groove 331. The first connecting part 352 is a hoop-like structure that connects to the latch body 351. The first connecting part 352 surrounds a portion of the outer periphery of the guide sleeve 320, and a hinge post 3521 is provided on the inner surface of the first connecting part 352 towards the guide sleeve 320. The axial direction of the hinge post 3521 is perpendicular to the axial direction of the guide sleeve 320. A hinge hole 321 is recessed inward on the periphery of the guide sleeve 320 corresponding to the position of the hinge post 3521, and the hinge post 3521 is rotatably inserted into the hinge hole 321. Preferably, there are two hinge posts 3521, which are arranged opposite to each other, and correspondingly, there are also two hinge holes 321, thereby ensuring that the latch 350 is tightly connected to the guide sleeve 320. A second connecting part 353 is connected to the first connecting part 352. The second connecting part 353 has a columnar structure, and its axial direction is consistent with the axial direction of the guide sleeve 320. The second connecting part 353 is arranged opposite to the mounting head 310. A third elastic element 360 is sleeved on the second connecting part 353. The third elastic element 360 is specifically a spring, and its two ends are in contact with the mounting head 310 and the first connecting part 352, respectively. The third elastic element 360 can provide a force to drive the latch 350 to the locked state. Preferably, there are two second connecting parts 353, located on the sides of the two hinge posts 3521, and correspondingly, there are also two third elastic elements 360.
[0072] When the dust cup cover 120 is in the closed state, the push rod 330 is retracted into the guide sleeve 320 by the resistance of the dust cup cover 120, and the second elastic element 340 is compressed at this time. When the dust cup cover 120 switches from the closed state to the open state, the push rod 330 extends out of the ash discharge port 112 under the push of the second elastic element 340. At the same time, the locking groove 331 gradually moves towards the locking buckle 350 and is embedded in the locking groove 331 under the action of the third elastic element 360, realizing the relative fixation of the push rod 330 and the guide sleeve 320. When the dust cup cover 120 switches from the open state to the closed state, the dust cup cover 120 can push the telescopic mechanism 300 to move along the axial direction, and drive the separator body 220 to move synchronously, so that the separator body 220 switches to the ash scraping state.
[0073] Furthermore, to ensure the separator body 220 returns to its working state under the action of the second elastic element 340 after being in the slagging state, thus ensuring the normal operation of the separator body 220, see [reference needed]. Figure 3 and Figure 5As shown, the mounting cylinder 215 and the end of the locking body 351 away from the locking part 3511 are respectively arranged opposite each other. The end of the locking body 351 away from the locking part 3511 is provided with a first guide slope 3512, and the end of the mounting cylinder 215 facing the locking 350 is provided with a second guide slope 2151. When the separator body 220 moves to the dust scraping state, the first guide slope 3512 and the second guide slope 2151 come into contact and guide the locking 350 to gradually turn to the unlocking state. When the separator body 220 is completely moved to the dust scraping state, the locking 350 releases the lock on the push rod 330. The separator body 220 is reset to the working state under the action of the first elastic member 216. At the same time, the rebound force of the first elastic member 216 is greater than the rebound force of the second elastic member 340. The retraction mechanism 300 moves towards the dust cup cover 120 under the drive of the separator body 220 and switches to the retraction state under the support of the dust cup cover 120.
[0074] Reference Figures 8 to 10 As shown, the cleaning process of the dust collection device of the present invention is as follows: The dust cup cover 120 is opened, and the push rod 330 extends out of the ash discharge port 112 under the push of the second elastic element 340. The latch 350 locks the push rod 330, achieving relative fixation between the push rod 330 and the guide sleeve 320. The user can then empty the dust inside the dust cup body 110. After emptying, the dust cup cover 120 is closed. The push rod 330 is pushed back axially to the ash discharge port 112 by the push of the dust cup cover 120. Since the push rod 330 and the guide sleeve 320 are relatively fixed, the push rod 330 will push the guide sleeve 320 and the separator body 220 together to move... When the separator body 220 moves to the dust scraping state, the base 210 can perform dust scraping operation on the separator body 220. When the dust cup cover 120 is completely closed, the separator body 220 is in the dust scraping state. At this time, the latch 350 switches from the locked state to the unlocked state under the guidance of the base 210, thereby releasing the lock on the push rod 330. The separator body 220 switches to the working state due to the rebound of the first elastic element 216. At the same time, the telescopic mechanism 300 moves together with the separator body 220, and the push rod 330 is retracted into the guide sleeve 320 by the resistance of the dust cup cover 120.
[0075] In addition, refer to Figure 11 As shown, the present invention also provides a vacuum cleaner, including the aforementioned dust collection device and a vacuum cleaner main unit 400, wherein the dust collection device is detachably mounted on the vacuum cleaner main unit 400. The vacuum cleaner main unit 400 is provided with a suction channel 410, which is connected to the air inlet 114 of the dust cup body 110. The vacuum cleaner main unit 400 is provided with a suction motor 420, which is connected to the exhaust port on the base 210.
