Description

Technical Field

[0001] This invention relates to vacuum cleaners, and more specifically, to a vacuum cleaner that uses negative pressure to draw in outside air, separates dust from the drawn-in air and collects it into a dust bin, and compresses the collected dust to reduce its volume. Background Technology

[0002] Generally, a vacuum cleaner is a household appliance that uses electricity to suck up small pieces of trash or dust and fills them into a dustbin inside the product; it is usually called a vacuum cleaner.

[0003] Vacuum cleaners can be categorized into manual vacuum cleaners, where the user moves the vacuum cleaner directly to perform cleaning, and automatic vacuum cleaners, which move automatically and perform cleaning. Manual vacuum cleaners can be further classified according to their shape, such as canister vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, and stick vacuum cleaners.

[0004] In the past, canister vacuum cleaners were the most common type of household vacuum cleaner. However, in recent years, there has been a growing trend towards handheld and stick vacuum cleaners that combine the dustbin and the vacuum cleaner body into one unit, improving ease of use.

[0005] In canister vacuum cleaners, the main body and the suction port are connected by a rubber hose or tube, and a brush can be inserted into the suction port as needed.

[0006] Handheld vacuum cleaners maximize portability. While lightweight, their short length can limit the cleaning area when seated. Therefore, they are best suited for cleaning specific areas such as table or sofa surfaces or car interiors.

[0007] Stick vacuum cleaners can be used standing up, allowing cleaning without bending over. This makes them advantageous for moving and cleaning in spacious areas. While handheld vacuum cleaners clean narrower spaces, stick vacuums can clean wider spaces and reach higher places that are inaccessible by hand. In recent years, stick vacuum cleaners have also been offered in modular versions, allowing for proactive changes in vacuum cleaner type to suit various applications.

[0008] The prior art provides a vacuum cleaner capable of compressing dust in a dustbin through the operation of a cleaning device, and easily expelling the dust from the dustbin. See below for reference. Figure 1 and Figure 2 This explains the existing technology. Figure 1 and Figure 2 The reference numerals in the accompanying drawings are limited to those in the prior art and are not applicable to the description of the vacuum cleaner of the present invention.

[0009] Figure 1This is a 3D diagram of a vacuum cleaner using existing technology. Figure 2 This diagram shows the configuration of the movable part 730, the filter part, and the air guide. (Refer to...) Figure 2 The existing method for compressing dust includes an operating unit 710, a transmission unit 720, and a movable unit 730. The operating unit 710 is a component operated by a user pressing with their finger. The movable unit 730 is disposed inside the dustbin and compresses the dust inside the dustbin by lifting and lowering. The transmission unit 720 is a component that transmits the drive of the operating unit 710 to the movable unit 730.

[0010] When the user operates the operation unit 710, the operation unit 710 descends. Since the operation unit 710 is fixedly connected to the transmission unit 720 and the movable unit 730, the transmission unit 720 and the movable unit 730 also descend as the operation unit 710 descends.

[0011] According to the prior art, a guide body 180 protrudes radially outward from one side of the dust bin. The guide body 180 communicates with the internal space of the dust bin. A hole is formed on the upper surface of the guide body 180, and a transmission part 720 is inserted into the hole. The transmission part 720 is partially inserted into the interior of the guide body through the hole, or partially extended outward from the guide body 180.

[0012] According to existing technology, when the movable part 730 rises or falls, the moving distance is the same as the length of the transmission part 720. That is, referring to... Figure 2 The movable part 730 descends to a length equivalent to the length by which the transmission part 720 is inserted into the guide body 180. However, during vacuum cleaner operation, since the movable part 730 should be close to the upper part of the dustbin, the operating part 710 and the transmission part 720 protrude upwards towards the guide body 180 and the upper part of the dustbin, thus causing inconvenience in terms of vacuum cleaner operation and aesthetics.

[0013] Reference Figure 1 To address the aforementioned problem, existing technology designs the upper part of the dustbin's main body cover 3 to be sufficiently high, and positions the operating part 710 below the upper surface of the vacuum cleaner body even when it moves upwards to its maximum extent, preventing the operating part 710 or the transfer part 720 from getting caught on furniture during cleaning. However, this design has the drawback of not being able to lower the height of the vacuum cleaner body to a sufficient degree.

[0014] Furthermore, according to the prior art, since the guide body 180 is connected to the internal space of the dust bin, if the dust is hooked by the guide body 180, the lower end of the transmission part 720 will be stuck by the dust and will not be able to continue to descend, thus further shortening the moving distance of the movable part 730. Summary of the Invention

[0015] The problem the invention aims to solve

[0016] The problem to be solved by the present invention is to address the issues of the prior art and provide a vacuum cleaner that is not limited by the height of the dustbin and the height of the vacuum cleaner body, and allows the compression plate to be raised and lowered fully.

[0017] Another problem to be solved by the present invention is to provide a vacuum cleaner that can prevent the compression plate from descending further due to dust accumulation during the lifting and lowering of the compression plate.

[0018] Another problem to be solved by the present invention is to provide a vacuum cleaner that can be separated according to its components so that the user can easily clean and keep it clean.

[0019] The subject matter of this invention is not limited to the subject matter described above, and those skilled in the art will clearly understand from the following description other subject matters not mentioned.

[0020] means for solving problems

[0021] To achieve the aforementioned goal, the vacuum cleaner of this embodiment can be separated into a dustbin with a slit formed on one side and a compression lever assembly. The compression lever assembly includes: a compression lever cover disposed outside the slit of the dustbin and mounted on the dustbin; a compression plate disposed inside the dustbin and moving up and down along the direction extending from the slit of the dustbin; a compression lever disposed on the compression lever cover and connected to the compression plate through the slit of the dustbin; and a sealing member disposed on the compression lever cover, in close contact with the slit of the dustbin and extending along the slit of the dustbin.

[0022] The vacuum cleaner may also include: a compression track disposed inside the compression lever housing and extending along the slit of the dust bin; and a compression guide, connected on one side to the compression plate and on the other side to the compression lever, the compression guide moving up and down along the compression track.

[0023] The vacuum cleaner may also include a compression guide, at least a portion of which is inserted into the interior of the dust bin through a slit in the dust bin, with one inserted side engaging with a compression plate and the other non-inserted side engaging with a compression lever, the compression guide moving up and down along the slit in the dust bin.

[0024] The sealing element may include: a fixing part, fixed to the compression lever cover; and a deformable part, supported by the fixing part, to seal the slit of the dust bin, but at least a portion of it deforms and forms a gap.

[0025] Multiple seals can be provided, and they can be arranged on the left and right sides with the slit of the dust bin as the center.

[0026] The dustbin of a vacuum cleaner can be formed in a cylindrical shape, and the slit in the dustbin can be formed in a direction parallel to the central axis of the dustbin.

[0027] The angle formed by the assumed line from the center of the vacuum cleaner's compression lever and dust bin to the central axis of the main body can be an acute angle.

[0028] The compression lever cover forms a slit parallel to the slit of the dustbin, and the vacuum cleaner may also include a shielding plate that covers at least a portion of the slit of the compression lever cover.

[0029] The vacuum cleaner may include: a compression lever housing mounting protrusion that protrudes outward from the outer periphery of the dust bin and in a direction different from the radial direction of the dust bin; and a compression lever housing mounting groove formed on one side of the compression lever housing for the compression lever housing mounting protrusion to be inserted.

[0030] In a vacuum cleaner, at least a portion of the main body can be inserted into one side opening of the dustbin, and the other side opening of the dustbin can be fixed to the main body.

[0031] The vacuum cleaner may include: a dustbin retaining protrusion formed in the dustbin; and a dustbin release lever disposed on the main body cover, which is hooked by the dustbin retaining protrusion to secure the dustbin and releases the dustbin retaining hook during operation.

[0032] When viewing the vacuum cleaner from one side, an assumed line extending along the direction of the compression lever's rise and fall can intersect the length axis of the handle.

[0033] When viewing a vacuum cleaner from one side, an assumed line extending along the direction of the compression lever's rise and fall can intersect the length axis of the suction section.

[0034] To achieve the aforementioned goal, the vacuum cleaner of this invention includes: a dustbin with a slit formed on one side; a compression lever cover disposed outside the slit of the dustbin and mounted on the dustbin; a compression plate disposed inside the dustbin and moving up and down along the direction extending from the slit of the dustbin; a compression lever disposed on the compression lever cover and connected to the compression plate through the slit of the dustbin; a compression guide, at least a portion of which is inserted into the dustbin through the slit, connected to the compression plate on the inner side and to the compression lever on the outer side, the compression guide moving along the slit of the dustbin; and a sealing member, with its front side in close contact with the slit of the dustbin and its side side in close contact with the compression guide.

[0035] Detailed descriptions of other embodiments are provided in the accompanying drawings.

[0036] Invention Effects

[0037] The vacuum cleaner of the present invention has one or more of the following effects.

[0038] First, the compression track is fixed outside the dustbin, and the compression plate and compression guide move up and down along the slit of the dustbin and the compression track. This has the advantage that the compression track, which corresponds to the transfer section in existing literature, does not protrude towards the top of the dustbin, and the height of the vacuum cleaner body can be designed to be lower.

[0039] Secondly, the compression track is located outside the dust bin. Since it lacks the structure corresponding to the guide body in the prior art, there is no possibility of dust getting trapped. Therefore, it does not have a structure that could hinder the lifting and lowering of the compression lever assembly, thus having the advantage of not being hindered by dust and ensuring the lifting and lowering of the compression plate.

[0040] Third, it has the advantage of easily separating the vacuum cleaner into a dustbin, cyclone section, and compression lever assembly, allowing users to easily clean each component and disinfect each part of the vacuum cleaner individually, thereby maintaining a clean state.

[0041] The effects of this invention are not limited to those described above, and those skilled in the art can clearly understand other effects not mentioned from the appended claims. Attached Figure Description

[0063] The advantages, features, and implementation methods of the present invention will become clearer through the detailed description of the embodiments below with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and can be embodied in many different forms. These embodiments are provided only to fully disclose the present invention and to completely reveal the scope of the invention to those skilled in the art. The invention is defined solely by the scope of the claims. Throughout this specification, the same reference numerals denote the same constituent elements. Hereinafter, the present invention will be described with reference to the accompanying drawings illustrating a vacuum cleaner 1 used to explain embodiments of the present invention.

[0064] Figure 3 This is a perspective view of a vacuum cleaner 1 according to an embodiment of the present invention. Figure 4 This is a top view of a vacuum cleaner 1 according to an embodiment of the present invention. Figure 5 This is a front view of a vacuum cleaner 1 according to an embodiment of the present invention. Figure 6 This is a rear view of a vacuum cleaner 1 according to an embodiment of the present invention. Figure 7 This is a right-side view of a vacuum cleaner 1 according to an embodiment of the present invention.

[0065] Reference Figures 3 to 7 According to one embodiment of the present invention, a vacuum cleaner 1 may include a main body 2. The main body 2 may include a suction section 10 for drawing in air containing dust.

[0066] Using the length axis A1 of the suction section 10 as a reference, the direction on the side where the suction section 10 is located is defined as forward, and the direction on the other side where the motor section 20 (described later) is located is defined as rearward. Figure 1 Using the main body 2 shown as a reference, the upper side is defined as above and the lower side is defined as below.

[0067] The main body 2 can be formed by the main body cover 3 to form its appearance.

[0068] Reference Figure 4 The main body 3 can be formed symmetrically about the central axis A0 of the main body.

[0069] A handle 40 is formed on the main body 3.

[0070] An intake section 10 is attached to the front of the main body 3.

[0071] A dust bin 60 is attached to the main body 3. An opening is formed at the joint between the hood 3 and the dust bin 60, and the hood 3 and the dust bin 60 are in communication with each other.

[0072] A portion of the lower front part of the main body cover 3 is inserted into the dust bin 60. A portion of the lower front part of the main body cover 3 can be inserted into the upper open part of the dust bin 60, so that the dust bin 60 is fixedly installed on the main body cover 3.

[0073] A battery 50 is attached to the lower part of the main body cover 3. More specifically, the battery 50 is located at the lower rear of the main body cover 3.

[0074] A suction motor 20 is attached to the upper part of the main body cover 3. The suction motor 20 can be attached to the upper rear part of the main body cover 3.

[0075] The suction unit 10 can be a hollow cylindrical shape, configured to draw in dust-containing air, and can provide a suction flow path for the dust-containing air to flow. The dust-containing air can be guided to the main body 2 through the suction unit 10.

[0076] The intake section 10 is connected to the inlet 311 of the cyclone section 30. Air drawn in from the nozzle passes through the intake section and flows into the cyclone section 30 through the inlet 311.

[0077] The main body 2 may also include a suction motor 20, a cyclone unit 30, a handle 40, and a battery 50.

[0078] The intake section 10 can be formed symmetrically about the length axis A1 of the intake section. (Refer to...) Figure 4 When viewed from above, the length axis A1 of the suction section can overlap with the central axis A0 of the main body. (Refer to...) Figure 7 When viewed from the side, the length axis A1 of the suction section can intersect with the central axis A2 of the motor, or the axis A3 of the cyclone flow, or the length axis A4 of the handle, or the central axis A5 of the dust bin, or the lifting direction A6 of the compression lever.

[0079] Here, the intake motor 20 is a component that generates airflow (i.e., airflow) so that dust-containing air can flow into the intake section 10.

[0080] The suction motor 20 is located inside the housing 3.

[0081] The suction motor 20 is located behind the dust bin 60. In other words, the suction motor 20 is located behind the cyclone section 30.

[0082] The central axis A2 of the suction motor is defined. The central axis A2 of the suction motor is aligned with the rotation axis of the shaft of the suction motor 20. Since the suction motor 20 of the present invention is equipped with an axial flow fan, the central axis A2 of the suction motor is parallel to the flow direction of the air passing through the suction motor 20.

[0083] The suction motor 20 can be a BLDC (Brushless DC) motor. A BLDC motor is a type of DC motor that does not have brushes. Because BLDC motors do not have brushes as wear parts, they have the advantages of low electrical and mechanical noise, no problems at high speeds, and low rotational noise.

[0084] The cyclone section 30 is connected to the suction section 10 and is constructed using the principle of a dust collector that utilizes centrifugal force to separate dust that is sucked into the interior of the main body 2 through the suction section 10.

[0085] Reference Figure 8 The cyclone section 30 is combined with the main body cover 3 or the dust bin 60 and is positioned between the suction section and the suction motor.

[0086] The cyclone section 30 is disposed between the suction section 10 and the suction motor 20. The suction section 10 is disposed upstream of the cyclone section 30, and the suction motor 20 is disposed downstream of the cyclone section 30. The suction section 10 is disposed in front of the cyclone section 30, and the suction motor 20 is disposed behind the cyclone section 30.

[0087] As an example, the cyclone section 30 may include a first cyclone 310 capable of separating dust using cyclone flow. The first cyclone 310 may be in communication with the suction section 10. Air and dust drawn in through the suction section 10 may spiral along the inner circumferential surface of the first cyclone 310.

[0088] The axis A3 of the cyclone flow of the first cyclone 310 can extend in the vertical direction.

[0089] The cyclone section 30 may further include a second cyclone 330 that further separates dust from the air discharged from the first cyclone 310. In this case, the second cyclone 330 may be disposed inside the first cyclone 310 to minimize the size of the cyclone section 30. The second cyclone 330 may include a plurality of cyclone bodies arranged in parallel. The air discharged from the first cyclone 310 may be divided and passed through by the plurality of cyclone bodies.

[0090] At this time, the axis of the cyclone flow of the second cyclone 330 can also extend in the vertical direction, and the axis A3 of the cyclone flow of the first cyclone 310 is arranged parallel to the axis of the cyclone flow of the second cyclone 330.

[0091] The axis of the first cyclone flow and the axis of the second cyclone flow can be collectively referred to as the axis A3 of the cyclone flow.

[0092] The axis A3 of the cyclone flow intersects the longitudinal axis A1 of the intake section. More specifically, the axis A3 of the cyclone flow can be configured to be perpendicular to the longitudinal axis A1 of the intake section. Therefore, the intake air flows rearward along the central axis A1 of the intake section and flows into the cyclone section 30 in a direction perpendicular to the axis A3 of the cyclone flow. With this configuration, there is an effect of preventing pressure loss when air flows from the intake section 10 into the cyclone section 30.

[0093] The main body 2 may also include a cyclone filter 350 configured to surround the second cyclone section 330. The cyclone filter 350 may be disposed on the inner circumferential surface of the first cyclone section 310. As an example, the cyclone filter 350 is formed in a cylindrical shape and guides the air separated from the dust in the first cyclone section 310 to the second cyclone 330. The cyclone filter 350 filters dust as the air passes through.

[0094] Therefore, the cyclone filter 350 may include a mesh portion having a plurality of holes. While not limited, the mesh portion may be formed of a metallic material.

[0095] The air present in the first cyclone 310 flows to the second cyclone 330. At this time, the air flows from the radial outside of the cyclone filter 350 to the radial inside of the cyclone filter 350.

[0096] On the other hand, as another example, the cyclone section 30 may also have a single cyclone, and in this case, the axis A3 of the cyclone flow may extend in the vertical direction.

[0097] Reference Figure 8 The cyclone section 30 has an inlet 311 formed radially along the dust bin 60. The inlet 311 is disposed on the central axis A1 of the suction section. The suction section 10 communicates with the cyclone section 30 through the inlet 311.

[0098] The cyclone section 30 has an outlet 312 formed along the length of the dust bin 60. In other words, the outlet 312 is formed along the axis A3 of the cyclone flow. The air that flows in the cyclone section 30 and is separated from the dust is discharged in the length direction of the dust bin 60 along the axis A3 of the cyclone flow and flows into the main body cover 3. The air flowing into the main body cover 3 passes through the filter 70 and the suction motor 20.

[0099] The handle 40, as a component that allows the user to hold and move the vacuum cleaner 1, is positioned opposite to the suction unit 10, with the cyclone unit 30 as the reference. The handle 40 has a generally cylindrical shape and extends along the axis A4 in the length direction. In addition, the handle 40 can be configured such that its upper part is tilted forward.

[0100] Reference Figure 8 The upper surface 41, the lower surface 42, the front end 43, and the rear end 44 of the handle are defined.

[0101] Reference Figure 8 The lower surface of the handle 40 is fixed to the main body cover 3. Additionally, a handle support member 45 extends from one side of the front end of the handle, fixing the handle 40 and the main body cover 3 together. More specifically, the rear end of the handle support member 45 is joined to the front end 43 of the handle and extends forward, with its front end joined to the main body cover 3. Since the upper surface 41 of the handle is separated from the main body cover 3, the handle support member 45 allows for a more secure connection between the handle 40 and the main body cover 3.

[0102] Reference Figure 8 The front end of the upper surface 41 of the handle is positioned on the upper part of the rear end. More specifically, the upper surface 41 of the handle is formed as an upward-facing inclined surface.

[0103] An operating unit 80 may be disposed on the upper surface 41 of the handle. The user can issue commands to the vacuum cleaner through the operating unit 80. The commands may include on / off switching and changes to all operating modes, including changes to the output of the suction motor.

[0104] Reference Figure 8 The upper surface 41 of the handle is separated from the main body cover 3. With this configuration, the vibration generated by the suction motor 20 will not be transmitted to the handle 40.

[0105] The battery 50 is a component used to power the suction motor 20. The upper side of the battery 50 can be configured to be adjacent to the handle 40, and the front can be configured to be adjacent to a lower portion of the outer peripheral surface of the dust bin 60, which will be described later.

[0106] The vacuum cleaner 1 may also include a dust bin 60 for storing dust separated from the cyclone section 30.

[0107] The dust bin 60 may include a cylindrical dust collection body 610. As an example, the dust collection body 610 may function as the first cyclone 310 without having a separate first cyclone 310. All or at least a portion of the second cyclone 330 may be located within the dust collection body 610.

[0108] A dust storage guide 604 can be configured within the dust collection body 610 to store dust separated from the second cyclone 330. The dust storage guide 604 can be attached to the lower part of the second cyclone 330.

[0109] The dust storage guide 604 divides the internal space of the dust collection body 610 into a first dust storage section 602 for storing dust separated from the first cyclone 310 and a second dust storage section 606 for storing dust separated from the second cyclone 330. In other words, the internal space of the dust storage guide 604 is the second dust storage section 606, and the space between the dust storage guide 604 and the dust collection body 610 is the first dust storage section 602.

[0110] A slit 611 is formed on one side of the dust bin 60.

[0111] Reference Figure 16 The slit 611 of the dust bin is formed on one side of the dust collection body 610. More specifically, the slit 611 of the dust bin is located on the rear right side of the dust collection body 610. However, it is not limited to this; the slit 611 of the dust bin may also be located on the left side or the front, within the range that can be easily used by a person of ordinary skill.

[0112] The slit 611 of the dust bin is disposed on the outer peripheral surface of the dust bin 60. The slit 611 of the dust bin extends toward the central axis A5 of the dust bin.

[0113] The slit 611 of the dust bin can be formed by penetrating the dust collection body 610, and the internal space of the dust bin 610 can be connected with the external space of the dust bin 610 through the slit 611.

[0114] Reference Figure 16 The slit 611 of the dust bin can be formed in a direction parallel to the central axis A5 of the dust bin. When the dust bin 60 is configured such that the central axis A5 of the dust bin is perpendicular to the ground, the slit 611 of the dust bin can be configured in a vertical direction. The compression plate 622 can move up and down along the slit 611 of the dust bin and move downward along the central axis A5 of the dust bin, thereby compressing the dust inside the dust bin 60.

[0115] A compression guide 625 is inserted into the slit 611 of the dust bin and slides along the slit 611 of the dust bin.

[0116] The following is for reference Figure 7 and Figure 8 The filter 70 will be described below.

[0117] The filter 70 is a component disposed in the airflow path and filters dust contained in the air. The filter 70 provided in the vacuum cleaner 1 of the present invention has a pre-filter 71 and a high-efficiency particulate air (HEPA) filter 73.

[0118] The pre-filter 71 is a component used to filter dust that is not collected in the cyclone section 30.

[0119] The pre-filter 71 is located upstream of the suction motor 20. (See reference...) Figure 8 The pre-filter 71 is disposed on the upper part of the cyclone section 30 and in front of the suction motor. Air is discharged to the upper part of the cyclone section 30 and flows into the suction motor from the front of the suction motor; therefore, the pre-filter 71 is disposed upstream of the suction motor.

[0120] Pre-filter 71 removes larger foreign objects from the air flowing into the intake motor upstream of the intake motor. Pre-filter 71 may be formed with a plurality of hollows, which can physically filter foreign objects larger than the size of the hollows.

[0121] The pre-filter 71 can be a mesh filter with a cylindrical shape. As an example, the pre-filter 71 may be made of nylon or spunbonded fabric. The spunbonded fabric is a type of nonwoven fabric made by heating and bonding synthetic fibers such as polypropylene (PP) after spinning.

[0122] In this invention, a vacuum cleaner 1 is described as including a pre-filter 71 and a high-efficiency filter 73, but the type and number of filters 71 are not limited.

[0123] Reference Figure 8 At least one of the pre-filter 71 or the high-efficiency filter 73 is configured on an extension of the central axis of rotation of the suction motor 20. (Refer to...) Figure 8 Viewed from the right, the pre-filter 71 is positioned on an extension line extending forward from the central axis A2 of the suction motor 20. The high-efficiency filter 73 is positioned on an extension line extending rearward from the central axis A2 of the suction motor. With this configuration, the air discharged from the pre-filter 71 flows into the suction motor 20 with almost no change in flow direction, thus preventing pressure loss due to airflow changes and improving the efficiency of the vacuum cleaner 1.

[0124] Reference Figure 8 The pre-filter 71 is inserted into the main body cover 3 from the front. More specifically, the pre-filter is inserted downwards and backwards on the upper front side of the main body cover 3. Conversely, the pre-filter 71 can be removed by pulling it forwards.

[0125] The pre-filter 71 can be formed elongated along the direction of insertion into the main body cover 3 and formed into a cylindrical shape with a space inside.

[0126] The front end of the pre-filter 71 is shaped to allow a user to hold it with their fingers and is sealed to prevent air leakage. The rear end of the pre-filter 71 is open to allow air to escape. A filter element is disposed on the outer peripheral surface between the front and rear ends of the pre-filter 71, allowing air to pass through while preventing dust from passing through. With this configuration, air moves from the outside of the pre-filter 71 through the filter element to the inside and is discharged from the rear end of the pre-filter 71.

[0127] A diffusion space 72 is formed between the outer peripheral surface of the pre-filter 71 and the main body cover 3.

[0128] Reference Figure 8 The upper surface of the pre-filter 71 is spaced apart from the main body shroud 3, and the lower surface of the pre-filter 71 is spaced apart from the cyclone section 30. The space formed between the pre-filter 71 and the shroud 3 is defined as the diffusion space 72. The diffusion space 72 is the space in which air flowing in from the cyclone section 30 diffuses before passing through the pre-filter 71. Air discharged from the cyclone section 30 can diffuse in the diffusion space 72 and flow along the outer peripheral surface of the pre-filter 71, allowing air to pass evenly across all surfaces of the outer peripheral surface.

[0129] The main body 2 may also include a high-efficiency filter 73 disposed between the pre-filter 71 and the motor unit 20. The full name of the high-efficiency filter 73 is a high-efficiency particulate air filter, which is a high-performance filter for filtering particulate matter.

[0130] The high-efficiency filter 73 can filter out the micro-dust that was not filtered in the pre-filter 71 at the end, and is contained inside the main body 3.

[0131] Air discharged from the cyclone section 30 and passing through the pre-filter 71 is discharged to the outside through the high-efficiency filter 73.

[0132] The high-efficiency filter 73 is positioned downstream of the suction motor 20. (See reference...) Figure 8 The high-efficiency filter 73 is positioned downstream of the intake motor 20. Since air flows in from the front of the intake motor 20 and exits to the rear of the intake motor 20, the high-efficiency filter 73 is positioned downstream of the intake motor 20.

[0133] The high-efficiency filter 73 removes smaller foreign objects from the air expelled downstream of the intake motor 20. The high-efficiency filter 73 can pull particles and filter them by applying electrostatic forces or the like to the filter material.

[0134] The airflow direction into the HEPA filter 73 is parallel to the airflow direction discharged from the intake motor 20. (Refer to...) Figure 8 Since the air discharged from the intake motor 20 moves from front to back, and the air flowing into the high-efficiency filter 73 also moves from front to back, the air flow direction in the high-efficiency filter 73 is parallel to the air flow direction discharged from the intake motor 20.

[0135] The HEPA filter is inserted parallel to the central axis A2 of the intake motor. More specifically, the HEPA filter is inserted in the same direction as the central axis A2 of the intake motor. Therefore, air flows in the same direction from the intake motor 20 to the HEPA filter 73, and since there is no change in air direction, there is almost no pressure loss.

[0136] The high-efficiency filter 73 is removed from the rear of the main body cover 3. When the user wants to separate the pre-filter 71, the pre-filter 71 can be removed only towards the front of the main body cover 3, and when the user wants to separate the high-efficiency filter 73, the high-efficiency filter 73 can be removed only towards the rear of the main body cover 3.

[0137] Air that has passed through the HEPA filter 73 is discharged to both sides of the HEPA filter 73. (Refer to...) Figure 3Exhaust ports are formed on the left and right sides of the HEPA filter 73. Therefore, the air that moves backward and passes through the HEPA filter 73 changes its flow direction to the left or right and is discharged to the left or right side of the vacuum cleaner 1.

[0138] Reference Figures 9 to 11 The vacuum cleaner 1 of the present invention can be decomposed into a plurality of units. Figure 9 Figure 10 is an exploded perspective view of the vacuum cleaner body 2 of the present invention, and is a diagram showing the operation of the dustbin disassembly lever 613b. Figure 11 This is a diagram showing the process of separating the vacuum cleaner body 2 of the present invention according to its various components.

[0139] Reference Figure 9 The vacuum cleaner 1 can be separated into a main body cover 3, a dust bin 60, a cyclone section 30, and a compression lever assembly 620. The compression lever assembly 620 can be separated into a compression plate 622 and the remaining components.

[0140] Referring to Figure 10, the dust bin 60 can be separated from the main body cover 3 by operating the dust bin disassembly lever 613b.

[0141] The dustbin 60 is detachable from the main body cover 3. One side of the main body cover 3 is inserted into an opening formed on one side of the dustbin 60 and supports the dustbin 60, while the other side of the main body cover 3 is hooked by the other side of the dustbin 60 and supports the dustbin 60. More specifically, the lower front part of the main body cover 3 is inserted into an opening formed on the upper part of the dustbin 60, supporting the upper part of the dustbin 60. The dustbin removal lever 613b of the main body cover 60 is hooked by a dustbin fixing protrusion 613a formed on the back of the dustbin 60, supporting the rear of the dustbin 60. The main body cover 3 is fixedly connected to the dustbin 60 by supporting the dustbin 60 at at least two points.

[0142] Referring to Figure 10, a dustbin fixing protrusion 613a is formed on the dustbin 60, and a dustbin removal lever 613b is disposed on the main body cover 3. The dustbin 60 is installed on the main body cover 3 by hooking and fixing the dustbin fixing protrusion 613a and the dustbin removal lever 613b together. When the fixing of the dustbin fixing protrusion 613a and the dustbin removal lever 613b is released, the dustbin 60 is removed from the main body cover 3.

[0143] A dustbin fixing protrusion 613a is formed in the dustbin 60. The dustbin fixing protrusion 613a protrudes rearward from the outer periphery of the dust collection body.

[0144] The dustbin removal lever 613b is disposed on the main body cover 3 and is hooked by the dustbin fixing protrusion 613a to fix the dustbin 60. It releases the dustbin fixing hook during operation. The dustbin removal lever 613b is disposed on the main body cover 3 in a height-adjustable manner.

[0145] Reference Figure 10a A hook that protrudes further downward is formed at the end of the dustbin fixing protrusion 613a. A hook that protrudes further upward is formed at the end of the dustbin disassembly lever 613b. The hooks of the dustbin fixing protrusion 613a and the dustbin disassembly lever 613b hook each other, thereby fixing the dustbin 60 to the main body cover 3.

[0146] Figure 10b The illustration shows the user sliding the dustbin removal lever 613b downwards to detach the dustbin 60. As the dustbin removal lever 613b descends, the latches of the hooks on the dustbin retaining protrusion 613a and the dustbin removal lever 613b are released. Thus, the dustbin 60 can be detached from the main body cover 3. More specifically, the dustbin 60 can be detached by rotating clockwise around its upper front portion.

[0147] Figure 11 The process of separating the vacuum cleaner body 2 of the present invention into its various components is shown.

[0148] Reference Figure 11 a. The dustbin 60 can be detached from the main body cover 3. With the dustbin 60 installed, as a portion of the main body cover 3 is inserted into the open portion of the dustbin 60, the upper part of the dustbin 60 is supported by the main body cover 3, and as the dustbin fixing protrusion 613a engages with the dustbin removal lever 613b, the rear of the dustbin 60 is supported by the main body cover 3. At this time, when the dustbin removal lever 613b is slid downward, the fixation at the rear of the dustbin 60 is released, and the dustbin 60 can be separated from the main body cover 3 by rotating the dustbin 60 clockwise around its upper front portion.

[0149] Reference Figure 11 b. The cyclone section 30 can be separated from the dust bin 60. The cyclone section 30 is housed in the dust bin 60 through the upper opening of the dust bin 60. Conversely, the cyclone section 30 can be drawn out to the upper part of the dust bin 60 and separated.

[0150] Reference Figure 11 c. The compression plate 622 can be separated from the dust bin 60. The compression plate 622 is attached to the compression guide 625, and the compression plate 622 can be separated from the compression guide 625 by rotating it clockwise or counterclockwise around the central axis A5 of the dust bin. The separated compression plate 622 can be led out upward through the upper opening of the dust bin 60 and separated from the dust bin 60.

[0151] Reference Figure 11d. The compression lever assembly 620 can be separated from the dust bin 60. A compression lever housing mounting protrusion 612 formed in the dust bin 60 is inserted into a compression lever assembly mounting groove 6213 formed in the compression lever assembly 620 and secured, thus mounting the compression lever assembly 620 to the dust bin 60. Conversely, after sliding downwards along the outer peripheral surface of the dust bin 60, the compression lever assembly 620 can move radially outwards from the dust bin 60 and separate from it.

[0152] As mentioned above, according to Figure 11 a to Figure 11 d. The vacuum cleaner body 2 can be separated into a main body cover 3, a dustbin 60, a cyclone unit 30, a compression plate 622, and a compression lever assembly 620 excluding the compression plate 622. This allows the user to keep the dustbin 60, cyclone unit 30, and compression plate 622 clean by washing them individually, while preventing malfunctions caused by water leakage from the main body cover 3.

[0153] Reference Figure 12 and Figure 16 The compression lever assembly 620 can be installed and removed from the dust bin 60. Figure 12 yes Figure 7 The planar sectional view of part C shows that the compression lever cover mounting protrusion 612 is hooked and fixed by the compression lever cover 621. Figure 16 This is a perspective view of the compression lever assembly 620 without the compression plate 622 in Figure 15, showing only the other components of the compression lever assembly 620. The shapes of the compression lever housing mounting protrusion 612 and the matching compression lever housing mounting groove 6213 can be seen.

[0154] Reference Figure 12 and Figure 16 The dustbin 60 has a compression lever cover mounting protrusion 612. Although the compression lever cover mounting protrusion 612 protrudes outward from the outer periphery of the dustbin 60, it protrudes in a direction different from the radial direction of the dustbin 60. A plurality of compression lever cover mounting protrusions 612 are arranged along the slit of the dustbin 60. The compression lever cover mounting protrusions 612 can be arranged symmetrically about the slit of the dustbin 60.

[0155] Reference Figure 12 The compression lever cover mounting protrusion 612 protrudes in a direction different from the radial direction of the dust bin 60. In other words, the compression lever cover mounting protrusion 612 does not protrude perpendicularly to the outer peripheral surface of the dust bin 60, but rather protrudes in an outward inclined direction. With this configuration, the compression lever cover mounting protrusion 612 can be firmly fixed to the compression lever cover mounting groove 6213.

[0156] Reference Figure 16The compression lever cover 621 has a mounting groove 623. A compression lever cover mounting protrusion 612 is inserted into the compression lever cover mounting groove 6213, and the compression lever cover 621 is mounted on the dust bin 60. The compression lever cover mounting groove 6213 is formed on one side of the compression lever cover 621, and the compression lever cover mounting protrusion 612 is inserted therein. A plurality of compression lever cover mounting grooves 6213 are arranged along the seal 626. The compression lever cover mounting grooves 6213 can be arranged symmetrically about the seal 626. The compression lever cover mounting grooves 6213 and the compression lever cover mounting protrusions 612 mate with each other.

[0157] The upper width of the compression lever cover mounting groove 6213 can be greater than the lower width. Therefore, the compression lever cover mounting protrusion 612 can enter from the upper part of the compression lever cover mounting groove 6213 and slide downwards, thereby being fixed at the lower part of the compression lever cover mounting groove.

[0158] Reference Figure 3 As shown in Figure 13, the vacuum cleaner 1 of the present invention includes a compression lever assembly 620. The compression lever assembly 620 is a component that compresses the dust collected inside the dust bin 60 to reduce its volume.

[0159] Reference Figure 13a During operation of the vacuum cleaner 1, the compression lever 623 and compression plate 622 are in close contact with the upper end of the dust bin 60. During operation of the vacuum cleaner 1, dust is separated from the air by spiral movement in the internal space of the dust bin 60 and is collected in the internal space of the dust bin 60.

[0160] Reference Figure 13b When the vacuum cleaner 1 stops, the compression lever 623 and compression plate 622 descend and pressurize the dust collected in the dust bin 60 to reduce its volume. (See reference...) Figure 13b Due to the limitation of the length of the compression lever cover slit 6212, the compression lever 623 and compression plate 622 can only descend to the middle position of the dust bin 60. However, they are not limited to this. By designing the compression lever cover slit 6212 to be longer, the compression plate 622 can descend to the bottom of the dust bin 60, which is different from the existing literature.

[0161] Reference Figure 14 As shown in Figure 15, the vacuum cleaner 1 of the present invention includes a compression lever cover 621. The compression lever cover 621 forms the exterior of the compression lever assembly 620, has an internal space, and houses the constituent elements constituting the compression lever assembly 620.

[0162] A compression lever cover 621 is disposed on the outside of the slit 611 of the dust bin and is installed on the dust bin 60. The compression lever cover 621 covers the slit 611 of the dust bin.

[0163] The inside of the compression lever cover 621 is open. The inner surface of the compression lever cover 621 faces the outer peripheral surface of the dust bin 60.

[0164] The inner side of the compression lever cover 621 is curved. Therefore, the inner side of the compression lever cover 621 is in close contact with the outer peripheral surface of the dust bin 60 without forming a gap.

[0165] The compression lever cover 621 is formed long along the slit 611 of the dust bucket.

[0166] The compression lever cover 621 has a slit 6212 parallel to the slit 611 of the dust bin. The slit 6212 of the compression lever cover is elongated along the slit 611 of the dust bin. The length direction of the slit 6212 of the compression lever cover is parallel to the length direction of the slit 611 of the dust bin. Therefore, the compression guide 625 is supported at two points along the slit 6212 of the compression lever cover and the slit 611 of the dust bin, and can slide and rise stably.

[0167] Referring to FIG15, the vacuum cleaner 1 of the present invention includes a compression plate 622. The compression plate 622 is located inside the dust bin 60 and is a component that compresses the dust collected inside the dust bin 60 to reduce its volume.

[0168] The compression plate 622 is disposed in the internal space of the dust bin 60 and moves up and down along the direction of the slit 611 of the dust bin.

[0169] The compression plate 622 is formed into a shape similar to a ring.

[0170] The inner circumferential surface of the compression plate 622 is in close contact with the inner circumferential surface of the first cyclone 320. In other words, the inner circumferential surface of the compression plate 622 is in close contact with the cyclone filter 350. Therefore, when the compression plate 622 is raised and lowered, the dust attached to the cyclone filter 350 can be swept out.

[0171] Referring to FIG15, the vacuum cleaner 1 of the present invention includes a compression lever 623. The compression lever 623 is a component that receives a force applied by a user and transmits the force to a compression plate 622, thereby moving the compression plate 622.

[0172] The compression lever 623 is disposed on the compression lever cover 621 and is connected to the compression plate 622 through the slit 611 of the dust bucket.

[0173] Compression lever 623 is disposed on the outer side of compression lever cover 621. Compression lever 623 moves up and down along the slit 6212 of compression lever cover.

[0174] Reference Figure 16 , Figure 19 as well as Figure 21 The vacuum cleaner 1 of the present invention includes a compression track 624 and a compression guide 625. The compression track 624 and the compression guide 625 are constituent elements that connect the compression plate 622 and the compression lever 623 and guide them during lifting and lowering.

[0175] The compression track 624, together with the compression guide 625, is a component that assists in raising and lowering the compression lever 623 and the compression plate 622 along the slit 611 of the dust bin. The compression track 624 is disposed inside the compression lever housing 621 and extends along the slit. More specifically, the compression track 624 may extend along the slit 6212 of the compression lever housing or along the slit 611 of the dust bin.

[0176] The compression track 624 is fixed inside the compression lever cover 621. More specifically, the upper or lower end of the compression track 624 is fixed inside the compression lever cover 621. Therefore, the compression track 624 will not rise or fall.

[0177] Compression track 624 is disposed on the outside of seal 626. Compression track 624 is isolated from dust collected inside dust bin 60 by being disposed on the outside of seal 626.

[0178] The compression track 624 extends along the slit 611 of the dust bin and guides the compression guide 625. More specifically, the compression track 624 is parallel to the length direction of the slit 611 of the dust bin and the length direction of the slit 6212 of the compression lever cover.

[0179] The compression guide 625, together with the compression track 624, is a component that helps to accurately raise and lower the compression lever 623 and the compression plate 622 along the slit 611 of the dust bin. One side of the compression guide 625 is engaged with the compression plate 622, and the other side is engaged with the compression lever 623, and it moves up and down along the compression track 624.

[0180] At least a portion of the compression guide 625 is inserted into the dust bin 60 through a slit, with the inserted side connected to the compression plate 622 and the uninserted side connected to the compression lever 623, and moves up and down along the slit 611 of the dust bin.

[0181] The compression guide 625 has a hollow structure extending vertically, into which a compression track 624 is inserted. The compression guide 625 slides along the compression track 624.

[0182] The compression guide 625 includes a compression plate connecting portion 6251, which protrudes radially inward from the hollow part of the compression guide 625 toward the dust bin 60.

[0183] The compression plate connector 6251 penetrates the seal 626. More specifically, the compression plate connector 6251 is inserted between the left seal 626a and the right seal 626b. The left side of the compression plate connector 6251 is in close contact with the left seal 626a, and the right side of the compression plate connector 6251 is in close contact with the right seal 626b.

[0184] The compression plate connector 6251 passes through the slit 611 of the dust bin. More specifically, the compression plate connector 6251 is inserted into the interior of the dust bin 60 through the slit 611. The two sides of the compression plate connector 6251 are adjacent to the seal 626 of the dust bin, so the compression plate connector 6251 can move up and down along the seal 626 of the dust bin.

[0185] A compression plate 622 is attached to the end of the compression plate connecting part 6251. (Refer to...) Figure 19 A hole is formed at the end of the compression plate connecting portion 6251. Although not shown in the figure, a fixing protrusion is formed on the compression plate 622 to be inserted into the hole. As the compression plate 622 rotates clockwise or counterclockwise, the fixing protrusion can be inserted into the hole of the compression plate connecting portion 6251, and the compression plate 622 can be fixedly connected to the compression plate connecting portion 6251.

[0186] A sealing groove may be formed at the connection between the compression plate connection 6251 and the compression track 624. At least a portion of the seal 626 is inserted into the sealing groove to fix its position. The sealing groove is formed by further recessing the compression plate connection 6251 inward. That is, the thickness of the portion of the compression plate connection 6251 in which the sealing groove is formed is thinner than the thickness of the portion in which the sealing groove is not formed.

[0187] The compression guide 625 includes a compression lever connection 6252, which protrudes from the hollow part of the compression guide 625 toward the slit 6212 of the compression lever cover.

[0188] Since the two sides of the compression lever connecting part 6252 are adjacent to the sealing part 626 of the compression lever cover, the compression lever connecting part 6252 can move up and down along the sealing part 626 of the compression lever cover.

[0189] A compression lever 623 is attached to the end of the compression lever connection 6252.

[0190] The angle formed by the extending direction of the compression plate connecting part 6251 and the extending direction of the compression lever connecting part 6252 can be an obtuse angle.

[0191] Reference Figure 20The vacuum cleaner 1 of the present invention includes a seal 626. The seal is a component that covers the slit 611 of the dustbin and seals the internal space of the dustbin 60.

[0192] A seal 626 is disposed on the compression lever cover 621, closely abutting against the slit 611 of the dust bin, and extending along the slit 611 of the dust bin. The slit extends along the central axis A5 of the dust bin, and the seal 626 may also extend along the central axis A5 of the dust bin.

[0193] The front of the seal 626 is in close contact with the slit 611 of the dust bin, and the side is in close contact with the compression guide 625.

[0194] Reference Figure 20 and Figure 21 The seal 626 includes a fixed part 6261 and a deformable part 6262.

[0195] The deformable part 6262 is supported by the fixed part 6261 and seals the slit, while at least a portion of it deforms and forms a gap.

[0196] The deformable portion 6262 is formed into a hollow cylindrical shape. The deformable portion 6262 extends along the central axis A5 of the dust bin. The upper and lower surfaces of the deformable portion 6262 may be open.

[0197] At least a portion of the deformable part 6262 can deform and more firmly seal the gap. (Refer to...) Figure 21 The front end of the deformable part 6262 can protrude forward toward the front of the compression lever cover 621. Therefore, when the compression lever cover 621 is installed on the dust bin 60, the front end of the deformable part 6262 is slightly recessed backward and fits tightly against the dust bin 60, which can more firmly seal the slit 611 of the dust bin so that it is not affected by the outside.

[0198] Reference Figure 21 One side of the deformable portion 6262 is in close contact with the compression guide 625. At this time, one side of the deformable portion 6262 is slightly pushed inward and in close contact with the compression guide 625, thereby eliminating the gap between the deformable portion 6262 and the compression guide 625. In particular, when the compression guide 625 descends, at the lower end of the compression guide 625, the deformable portion 6262 deforms and forms a gap for the compression guide 625 to move. At the upper end of the compression guide 625, the deformable portion 6262 returns to its original shape and removes the gap between it and the compression guide 625, thereby maintaining a sealed state between the seal 626 and the compression guide 625.

[0199] The fixing part 6261 is fixed to the compression lever cover 621. The fixing part 6261 protrudes outward from the outer peripheral surface of the deformable part 6262. The fixing part 6261 extends along the central axis A5 of the dust bin. The fixing part 6261 can be formed in the shape of a plate.

[0200] The end of the fixing part 6261 can be inserted into the compression lever cover 621. A long groove can be formed in the compression lever cover 621, and as the fixing part 6261 is inserted into the groove, the seal 626 can be disposed on the compression lever cover 621.

[0201] The fixing part may be composed of a first extension 6261a and a second extension 6261b.

[0202] The first extension 6261a extends along the outer peripheral surface of the dust bin 60 in the deformed portion. The first extension 6261a can extend along the central axis A5 of the dust bin. That is, the first extension 6261a can extend toward the outer peripheral surface of the dust bin 60 and can be formed into a plate shape extending along the central axis A5 of the dust bin.

[0203] The first extension 6261a may be formed as a curved surface along the outer peripheral surface of the dust bin 60. Alternatively, the first extension 6261a may also be formed as a flat surface.

[0204] The second extension 6261b extends from the end of the first extension 6261a toward the compression lever cover 621, and at least a portion thereof is inserted into a groove formed in the compression lever cover 621. The second extension 6261b may extend rearward from the end of the first extension 6261a. The second extension 6261b is inserted into the groove formed in the compression lever cover 621, thereby fixing the seal 626 to the compression lever cover 621. The second extension 6261b may be formed elongated vertically along the central axis A5 of the dust bin.

[0205] Reference Figure 12 and Figure 21 A plurality of seals 626 are provided. The plurality of seals 626 are arranged on the left and right sides of the slit 611 of the dust bin as the center. The left seal 626a is arranged on the left side of the slit 611 of the dust bin, and the right seal 626b is arranged on the right side of the slit 611 of the dust bin.

[0206] Reference Figure 12 and Figure 21 The left seal 626a is in close contact with the left end of the compression guide 625. Additionally, the right seal 626b is in close contact with the right end of the compression guide 625.

[0207] The front end of the left seal 626a is in close contact with the outer peripheral surface of the dust bin 60, the front end of the right seal 626b is in close contact with the outer peripheral surface of the dust bin 60, and the right end of the left seal 626a is in close contact with the left end of the right seal 626b, so that the seal 626 seals the slit 611 of the dust bin and can block the internal space of the dust bin 60 from the outside.

[0208] Reference Figure 12 The angle (angle 1) formed by an assumed line passing through the slit 611 of the dust bin and the center of the dust bin, and the central axis A0 of the main body, is an acute angle. A compression lever 623 is arranged radially from the slit 611 of the dust bin toward the dust bin 60. Therefore, the user can hold the handle 40 with their right hand and press the compression lever 623 with their left hand to slide the compression lever 623 along the slit 611 of the dust bin. Alternatively, the user can also hold the handle 40 with four fingers of their right hand and press the compression lever 623 with their thumb to slide it along the slit 611 of the dust bin.

[0209] Reference Figures 17 to 19 The vacuum cleaner 1 of the present invention includes a shielding plate 627. The shielding plate 627 is a component that covers the slit 6212 of the compression lever cover and shields the internal space of the compression lever cover 621.

[0210] A shielding plate 627 covers at least a portion of the slit 6212 of the compression lever cover. The slit 6212 of the compression lever cover is formed elongated vertically. The shielding plate 627 is formed in the shape of a plate that is formed elongated vertically, covering the slit 6212 of the compression lever cover, thereby isolating the internal space of the compression lever cover 621 from the outside.

[0211] Reference Figure 17 and Figure 18 The shielding plate 627 can be divided into an upper shielding plate 6271 and a lower shielding plate 6272.

[0212] The upper end of the upper shielding plate 6271 is connected to the compression lever 623 or the compression guide 625, and moves up and down together with the compression lever 623. The lower shielding plate 6272 is disposed below the upper shielding plate 6271, and at least a portion thereof is configured to overlap the upper shielding plate 6271 front and back.

[0213] The upper shielding plate 6271 can be disposed inside the lower shielding plate 6272. With this configuration, when the compression lever 623 descends, causing the upper shielding plate to descend completely to the lower critical position, the compression lever 623 contacts the upper end of the lower shielding plate, thereby enabling the lower shielding plate to descend together with the upper shielding plate.

[0214] When the vacuum cleaner 1 is viewed from one side, an assumed line A6 extending along the direction of the compression lever 623 intersects the length axis A4 of the handle.

[0215] Reference Figure 7 An assumed line A6 extending along the lifting direction of the compression lever 623 is vertically arranged, while the length axis A4 of the handle is arranged forward. Therefore, the assumed line A6 extending along the lifting direction of the compression lever 623 at the top of the vacuum cleaner 1 can intersect the length axis A4 of the handle. With this configuration, during cleaning, the length axis A4 of the handle can be set horizontally to the ground, and at this time, the assumed line A6 extending along the lifting direction of the compression lever 623 is arranged downwards and backwards, allowing the user to easily operate the compression lever 623 by pulling it towards their body.

[0216] When the vacuum cleaner 1 is viewed from one side, an assumed line A6 extending along the direction of the compression lever 623 is intersected with the length axis A1 of the suction section.

[0217] Reference Figure 7 An assumed line A6 extending along the lifting direction of the compression lever 623 is arranged vertically, and the length axis A1 of the suction unit is arranged in the forward direction. Therefore, the assumed line A6 extending along the lifting direction of the compression lever 623 at the upper part of the vacuum cleaner 1 can intersect with the length axis A4 of the handle. With this configuration, during cleaning, the length axis A4 of the suction unit is arranged to tilt towards the ground, and at this time, the assumed line A6 extending along the lifting direction of the compression lever 623 is arranged in the rearward direction, so that the user can easily operate the compression lever 623 by pulling it towards the body side.

[0218] The function and effects of the vacuum cleaner 1 of the present invention described above will be explained below.

[0219] Reference Figures 9 to 1 The vacuum cleaner 1 of the present invention can be disassembled into a plurality of parts. The vacuum cleaner 1 can be separated into a main body cover 3, a dustbin 60, a cyclone section 30, and a compression lever assembly 620. The compression lever assembly 620 can be separated into a compression plate 622 and remaining components. In the separated parts, the dustbin 60, the cyclone section 30, and the compression plate 622 are constantly exposed to dust, resulting in dirt and difficulty in cleaning. The dustbin 60 and the cyclone section 30 are washable parts. Since there is a risk of malfunction when the main body cover 3 is immersed in water, separating and washing the dustbin 60 and the cyclone section 30 allows for disinfection and maintenance of the dustbin 60. Similarly, the compression plate 622, being a washable part, can be disinfected and maintained in a clean state.

[0220] In particular, referring to FIG10, the buckle at the rear of the dust bin 60 is removed by operating the dust bin disassembly lever 613b, and the buckle at the top of the dust bin 60 is removed by rotating it clockwise, thereby making it easy to remove the dust bin 60 from the main body cover 3, and during installation, it can be easily installed and securely fixed.

[0221] The compression lever assembly 620 of the present invention includes: a compression plate 622 disposed within the internal space of the dustbin 60; a compression lever 623 operable by a user; a compression guide 625 connecting the compression plate 622 and the compression lever 623; and a compression track 624 passing through the compression guide 625 and guiding its sliding movement. Referring to FIG13, the assembly combining the compression plate 622, the compression guide 625, and the compression lever 623 has a significantly reduced height compared to the prior art, resulting in a greatly increased travel distance without being limited by the height of the vacuum cleaner 1 alone.

[0222] Reference Figure 12 and Figure 16 The compression lever assembly 620 can be installed and removed from the dust bin 60. More specifically, the compression lever cover mounting protrusion 612 formed in the dust bin 60 is inserted into the compression lever cover mounting groove 6213 formed in the compression lever cover 621, so that the compression lever cover 621 slides along the length direction of the slit 611 in the dust bin, thereby making it easy to install the compression lever assembly 620 in the dust bin 60.

[0223] Reference Figure 20 and Figure 21 The compression lever assembly 620 includes a seal 626 that seals the gap. The seal 626 is disposed on the outside of the slit 611 of the dust bin, thus isolating the internal space of the dust bin 60 from the outside. The seal 626 includes a cylindrical deformable portion 6262, at least a portion of which is recessed and more firmly adheres to the outer peripheral surface of the dust bin 60 to achieve a seal. The deformable portion 6262 is disposed on the left and right sides of the compression guide 625, and is able to deform only partially and form a gap when the compression guide 625 slides, returning to its original shape and sealing the gap after the compression guide 625 moves. The seal 626 includes a fixing portion 6261 that protrudes from the deformable portion 6262 and is inserted into and fixed to the cover, thereby easily and securely fixing it to the compression lever cover 621.

[0224] While preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the specific embodiments described above. Various modifications can be made by those skilled in the art without departing from the spirit of the invention as claimed in the claims, and these modifications should not be understood solely from the technical concept or prospect of the present invention.
