Description

[Technical Field]

[0001] The present invention relates to the field of cleaning equipment technology, and more particularly to a skirt separator device and cleaning equipment therefor. [Background technology]

[0002] Among cleaning appliances, handheld cleaning appliances are generally used by users for cleaning their homes, and have a cyclone separating unit provided in a dust cup.

The separation chamber includes a cyclone separating section located at one end of the dust cup and a dirt collecting section located at the other end of the dust cup. Dirt is separated in the cyclone separating unit by airflow flowing around the separation chamber. The separated clean air passes through a strainer in the cyclone separating unit to proceed to the next separation step. However, as the air flows around the inside of the separation chamber, the dirt separated from the airflow is re-entered by the airflow. To prevent the cyclone separating section and the dirt collecting section from affecting each other and to improve the dust and air separation efficiency of the cyclone separating unit, a partition skirt is usually provided between the cyclone separating section and the dirt collecting section.

[0004] In the prior art, the structure of some of the partition bottom edges makes them too hard, making it difficult for large-sized dirt to fall into the dirt collection section, and when removing and installing the cyclone separation unit, interference with the dust cup components is likely to occur, making it difficult to remove the cyclone separation unit.In addition, the structure of some of the partition bottom edges makes them too hard, making it difficult to achieve effective separation.

[0020] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments with reference to the accompanying drawings. Directional nouns such as "upper", "lower", "left" and "right" referred to in this specification are based on the orientation of Fig. 1. The side where the main body 80 is located is defined as the "lower" part, and the side where the dust cup 20 and the main engine 60 are located is defined as the "upper" part.

[0021] In one aspect, as shown in FIG. 1, the cleaning appliance provided in the embodiment of the present invention includes a main body 80, a main engine 60 attached to the main body 80, a dust cup 20, and a removable cyclone separating unit 10 provided in the dust cup 20, and further includes a scraping device used in the cleaning appliance.

[0022] The dust cup 20 and the main machine 60 are mounted on the main body 80, the scraping device is fixedly mounted on the dust cup 20, and the scraping device and the main machine 60 are connected via an engaging structure.

[0023] The main engine 60 includes a main engine housing 61 and a fan 62 mounted within the main engine housing 61 .

[0024] A cylindrical connecting tip extends outward from the lower end surface of the main engine housing 61, and three locking blocks 63 are integrally formed at equal intervals on the outside of the connecting tip to fit into the locking grooves 31 opened in the scraping device on the dust cup 20. The provision of the locking blocks 63 and locking grooves 31 allows for quick installation and easy removal of the dust cup 20 and main engine 60.

[0025] The fan 62 is electrically connected to a main control circuit inside the body 80 to draw in outside air.

[0026] Example 1 Based on the above technical solution, and referring to Figures 2 and 3, the scraping device includes a scraping member, and the scraping member has a connecting portion extending in the removal direction of the cyclone separating unit 10, and a scraping portion extending toward the inside of the dust cup 20 perpendicular to the removal direction and slidably abutting the cyclone separating unit 10.

[0027] The dust cup 20 has a cylindrical dust cup body and an opening provided at one end of the dust cup body, and the scraping member is a cylindrical scraping ring 50, which is attached coaxially to the opening of the dust cup 20.

[0028] The cyclone separating unit 10 is coaxially disposed within the dust cup 20, and includes a cylindrical strainer 11 and a cyclone separating section located downstream of the strainer 11. The scraping ring 50 can scrape foreign matter from the outside of the strainer 11 so that the foreign matter falls into the dust cup 20.

[0029] The main body 80 is formed as a gun-like structure and includes a first horizontal connecting portion 82 extending generally horizontally and a handle portion 81 extending generally vertically. A fluid passage extending generally horizontally is provided within the first horizontal connecting portion 82, with one end of the fluid passage being an air intake port and the other end being connected to the dust cup suction port 21 of the dust cup 20. The dust-laden airflow enters the fluid passage's air intake port of the first horizontal connecting portion 82, passes through the dust cup suction port 21, and enters the dust cup 20, where it is separated into dust and air by the cyclone separating unit 10 provided coaxially within the dust cup 20. Referring to FIG. 1, a first cyclone separation stage is formed between the inner wall of the strainer 11 and the inner wall of the dust cup 20, and the first cyclone separation stage can perform preliminary dust and air separation for the dust-containing airflow. A skirt partitioning device is provided at the left end of the strainer 11, away from the opening, and the chamber inside the dust cup 20 is divided by the skirt partitioning device into a cyclone separation section (i.e., the first cyclone separation stage) and a dirt collection section.

[0030] Specifically, the dust-laden airflow entering the dust cup 20 first travels around the strainer 11, undergoing a first cyclone separation. A first cyclone separation stage is formed between the strainer 11 and the dust cup 20, and the dirt separated in the first cyclone separation stage is collected in a first dirt collection area. The gas separated after passing through the first cyclone separation stage then passes through holes in the strainer 11 and enters multiple cyclone cones inside the strainer 11, undergoing a second cyclone separation. The multiple cyclone cones inside the strainer 11 form a second cyclone separation stage. The dirt separated after passing through the second cyclone separation stage is discharged from the dirt outlets of each cyclone cone and collected. Referring to FIG. 1 , the left side of the cyclone cones is the second dirt collection area, which collects the dirt discharged from each cyclone cone. The gas separated in the second cyclone separation stage passes through the exhaust port of the cyclone cone and is discharged downstream to a HEPA filtering device or the like, and ultimately to the outside.

[0031] The strainer 11 is a perforated plate made of a hard material, such as a metal plate. The purpose of the holes is to facilitate the passage of gas separated in the first cyclone separation stage, retain large-sized dirt particles on the outside of the strainer 11, and allow the dust-laden airflow that enters the strainer 11 to pass through the second cyclone separation stage, where dust and air are separated. The multiple cyclone cones in the second cyclone separation stage are arranged in a ring, and a storage space is formed between the left ends of the multiple cyclone cones to store dirt from a certain second dirt collection area.

[0032] Specifically, the structure in which multiple cyclone cones are arranged in a ring allows the space for arranging the cyclone separating unit 10 to be fully utilized, making the structure of the cyclone separating unit 10 compact and allowing more cyclones to be arranged in a limited space, thereby improving the dust and air separation efficiency of the cyclone separating unit 10.

[0033] More specifically, the hand-held portion 81 is located between the first lateral connection portion 82 and the second lateral connection portion 83. A main control circuit is fixedly connected within the hand-held portion 81, and the main control circuit is electrically connected to the fan 62 via a start switch to control starting and stopping of the fan 62.

[0034] The left end of the first lateral connection portion 82 is an intake duct, and the dust cup 20 is removably attached to the first lateral connection portion 82 .

[0035] A battery pack 100 is provided in the second lateral connection portion 83 to supply power to the main control circuit in the hand-held portion.

[0036] Example 2 The scraping device includes a scraping member, and the scraping member has a connection portion extending along the removal direction of the cyclone separating unit 10 and a scraping portion extending perpendicular to the removal direction toward the inside of the dust cup 20 and slidably abutting the cyclone separating unit 10.

[0037] The dust cup 20 has a cylindrical dust cup body and an opening provided at one end of the dust cup body, and the scraping member is a cylindrical scraping ring 50, which is attached coaxially to the opening of the dust cup 20.

[0038] A skirt partition device is fixedly attached to the bottom of the cyclone separating unit 10, and when the cyclone separating unit 10 is removed from the dust cup 20, the scraping device is used to scrape foreign matter from the first surface of the skirt body 2 on the skirt partition device at the bottom of the cyclone separating unit 10 into the dust cup 20.

[0039] The space between the dust cup 20 and the cyclone separating unit 10 is referred to as the separation chamber. The left side of the separation chamber of the dust cup 20 of the skirt separator device is referred to as the dirt collecting section. The right side of the separation chamber of the dust cup 20 is referred to as the cyclone separating section. When the dust collector is used to clean low surfaces such as floors, sofas, and beds, the dirt collecting section is located below the cyclone separating section in the direction of gravity, which helps dust to concentrate in the dirt collecting section due to its own gravity.

[0040] Based on the above-described first and second embodiments, the dust cup body has a side wall with a dust cup inlet 21 that communicates with the intake duct. External dust-laden airflow drawn in by the fan 62 enters the intake duct, passes through the dust cup inlet 21, and enters the separation chamber, where dust and air are separated. During use, the dirt collection section is typically located below the cyclone separation section in the direction of gravity. Therefore, any dirt separated by the separation chamber accumulates in the dirt collection section due to the action of gravity. The intake duct 10 is located at the first horizontal connection 82 of the body 80 and communicates with the dust cup inlet 21. The intake duct 10 is provided with a structure that causes the incoming dust-laden airflow to spiral. Specifically, by changing the dust-laden airflow from a linear flow to a spiral flow, centrifugal force is increased, improving the dust collection effect. The dust cup 20 has a dust guide opening at its left end and a dust cup end cap 22 that can close the dust guide opening. The dust cup end cap 22 is attached to the dust cup body via a hinge member, and the tip of the dust cup end cap 22 has an engaging member that holds the dust cup end cap 22 in the closed position. Specifically, the dust cup end cap 22 can rotate between the closed position and the open position. In the closed position, the dust cup end cap 22 keeps dirt in the dirt collecting section, and in the open position, dirt can be removed from the dirt collecting section.

[0041] Furthermore, the radial cross section of the scraper ring 50 is "L" shaped. The horizontal part of the "L" shape is the connecting part, and the vertical part of the "L" shape is the scraping part. The "L" shape has a simple structure, is more compact than the conventional technology, and occupies a small proportion of space, minimizing interference between the scraper ring 50 and other components on the cyclone separating unit 10. Of course, the radial cross section is not limited to the "L" shape, and may also have a "T" shape.

[0042] Furthermore, the scraper ring 50 includes a mounting ring 51 and an annular scraper plate 52. The outer wall of the mounting ring 51 is fixedly connected within the dust cup 20. The annular scraper plate 52 is an "L"-shaped vertical scraper portion that is integrally formed with the mounting ring 51 on one side of the opening of the dust cup 20 and extends radially inward to abut against the strainer 11. When the cyclone separating unit 10 is removed from the dust cup 20, the strainer 11 slides past the annular scraper plate 52 so that foreign matter is scraped off.

[0043] Furthermore, the initial position of the annular scraping plate 52 is the position where the inner ring of the annular scraping plate 52 abuts against the base 111 of the strainer 11. The annular scraping plate 52 scrapes the strainer 11 from the base 111 of the strainer 11, and further ensures that dust from the entire strainer 11 can be scraped by the scraping ring 50, improving the scraping effect of the annular scraping plate 52.

[0044] The scraping device further includes a connecting base 30 coaxially mounted on the scraping ring 50 and a scraping ring mounting frame 40. The connecting base 30 is fixed to the opening of the dust cup 20, the scraping ring mounting frame 40 is mounted within the connecting base 30, and the side of the scraping ring mounting frame 40 remote from the opening is fixedly connected to the scraping ring 50. Preferably, the scraping ring 50 is detachably connected to the scraping ring mounting frame 40, which makes it easy to replace the scraping ring 50.

[0045] Specifically, a positioning protrusion is formed between the connection base 30 and the scraping ring mounting frame 40 to limit the circumferential direction of the scraping ring 50 in the dust cup 20, and the connection base 30 is fixed to the dust cup 20 by adhesive bonding.

[0046] Based on the above technical solution, as shown in FIG. 2, the scraping device in this embodiment further includes a support washer 70, which is coaxially mounted within the mounting ring 51. The outer circumferential surface of the support washer 70 abuts against the inner circumferential surface of the mounting ring 51, and the end of the support washer 70 abuts against the annular scraping plate 52 to support the mounting ring 51 and the annular scraping plate 52, thereby improving the overall strength of the scraping ring 50 and its scraping effect. The main engine 60 and the dust cup 20 are coaxially connected via a locking structure. The scraping device is mounted in the opening where the dust cup 20 and the main engine housing 61 connect.

[0047] Furthermore, an annular positioning step is formed at the connection point between the inner wall of the connection base 30 and the scraper ring mounting frame 40 to position the cyclone separating unit 10, and a fitting step that fits into the annular positioning step is formed on the cyclone separating unit 10. By mounting the cyclone separating unit 10 so that it engages exactly with the positioning step, the base 111 on the strainer 11 abuts against the annular scraper plate 52, facilitating accurate positioning and quick mounting of the cyclone separating unit 10.

[0048] Furthermore, a seal ring is provided between the annular positioning step and the fitting step to improve the sealing performance of the connection between the cyclone separating unit 10 and the dust cup 20.

[0049] Furthermore, a rubber material such as TPU is used for the scraping ring 50. This improves the deformability of the scraping ring 50 when it moves relative to the cyclone separating unit 10, and also reduces interference with components such as the skirt separator of the cyclone separating unit 10.

[0050] Example 3 As shown in Figures 4 to 6, the skirt separator is used in a cyclone separating unit attached to a cleaning machine. The skirt separator has an annular structure. The skirt separator includes an annular inner ring 1 and an annular skirt body 2.

[0051] The skirt body 2 has a root portion connected to the inner ring 1, and the end of the skirt body 2 away from the inner ring 1 is an edge portion. The diameter of the edge portion is larger than the diameter of the root portion. The skirt body 2 has a plurality of crushed portions spaced apart along the circumferential direction of the skirt body 2. 3 is The crushed portion 3 is formed as a long structure extending along the radial direction of the skirt side main body 2.

[0052] The crushed portion 3 extends along the thickness direction of the bottom hem body 2, protruding from the bottom hem body 2 on one surface of the bottom hem body 2 and recessed from the bottom hem body 2 on the other surface of the bottom hem body 2. On the one surface of the bottom hem body 2, the size of the crushed portion 3 protruding from the bottom hem body 2 gradually decreases from the base to the edge.

[0053] The present invention provides a skirt separator comprising an inner ring 1 and a skirt body 2, with a number of flattened sections 3 formed on the skirt body 2, each of which protrudes from one surface of the skirt body 2 and is recessed from the other surface of the skirt body 2. On one surface of the skirt body 2, the flattened sections 3 gradually decrease in size from the base to the edge. Compared to the prior art, this provides a more effective separation effect. The structure is simple, the flattened sections 3 are rationally arranged, and the arc-shaped connections between adjacent flattened sections 3 easily deform to allow dirt to pass through. This ensures that the overall structure of the skirt separator is of adequate rigidity, reduces interference with components on the dust cup, and effectively separates dirt, allowing it to smoothly flow into the dirt collection section.

[0054] Furthermore, on the other side surface of the skirt body 2, the size of the depression of the crushed portion 3 in the skirt body 2 gradually decreases from the base portion to the edge portion, and / or The size of the collapsed portion 3 extending along the circumferential direction of the skirt body 2 gradually decreases from the root to the edge, which ensures effective separation of dirt and facilitates smooth flow of the dirt into the dirt collecting section.

[0055] Furthermore, as shown in Figure 5, a first arc-shaped connection portion 31 is formed on one side of the crushed portion 3 along the circumferential direction of the bottom edge body 2, and a second arc-shaped connection portion 32 is formed on the other side of the crushed portion 3, and the second arc-shaped connection portion 32 of one crushed portion 3 is connected to the first arc-shaped connection portion 31 of another adjacent crushed portion 3, and an arc-shaped connection portion is formed between the crushed portion 3 and the surface of one side of the bottom edge body 2, resulting in a beautiful appearance.

[0056] The surface on one side of the skirt side main body 2 is defined as the surface on which the connection point between the first arc-shaped connecting portion 31 and the second arc-shaped connecting portion 32 exists.

[0057] Furthermore, an arc-shaped connection is formed between the crushed portion 3 and the surface of the other side of the skirt body 2.

[0058] Furthermore, along the circumferential direction of the hem body 2, a third arc-shaped connecting portion is formed on one side of the crushed portion 3, and a fourth arc-shaped connecting portion is formed on the other side of the crushed portion 3, and the fourth arc-shaped connecting portion of one crushed portion 3 is connected to the third arc-shaped connecting portion of another adjacent crushed portion 3.

[0059] Furthermore, on one surface of the skirt body 2, the size of the collapsed portion 3 protruding from the skirt body 2 gradually decreases from the root to the edge until it disappears, and on the other surface of the skirt body 2, the size of the collapsed portion 3 recessed into the skirt body 2 gradually decreases from the root to the edge until it disappears, thereby smoothing the edges, and / or The inner ring 1 is an annular structure, and its inner wall has an engagement portion for connecting to the cyclone separation unit 10, which makes it easy to attach and detach the inner ring 1 from the cyclone separation unit 10. The inner ring 1 is an annular structure, and its inner wall has an engagement portion for connecting to the cyclone separation unit 10. The inner ring 1 is integrally molded with the root portion in the circumferential direction of the outer wall of the inner ring 1. The root portion of the skirt body 2 is formed in a wavy shape in the circumferential direction of the outer wall of the inner ring 1. An annular engagement groove is opened in the left end face of the inner ring 1, which is used for assembling with the bottom portion of the cyclone separation unit 10.

[0060] Furthermore, the material of the skirt separator is silica gel, which has a high deformation effect and facilitates the smooth passage of dirt.

[0061] The skirt separator is angled toward the outer wall of the dust cup 20 and extends away from the central axis; and / or The dust cup 20 includes a cylindrical body, along the axial direction of which a dust cup end cap 22 is provided at one end of the cylindrical body, an opening is provided at the other end of the cylindrical body, a skirt divider device is located in the middle of the cylindrical body, a dirt collection section is formed between the dust cup end cap 22 and the skirt divider device, a cyclone separation section is formed between the opening and the skirt divider device, and the skirt body extends obliquely toward the dirt collection section.

[0062] Furthermore, the skirt body 2 is made from an elastically deformable material.

[0063] The skirt body 2 is pushed and deformed toward the central axis and away from the opening on the dust cup 20, so that the skirt body 2 is located at the first position, The bottom side body 2 is pushed in the direction opposite to the first position and deformed, so that the bottom side body 2 is located at the second position, and the bottom side body 2 is deformed between the first position and the second position.

[0064] Specifically, when the cyclone separating unit is removed from the dust cup 20, the skirt body 2 is pushed as it passes through the scraping structure, contracting and deforming in the direction opposite to the removal direction of the cyclone separating unit, and folding at the collapsed portion 3 (similar to the state when an umbrella is folded), so that the skirt body 2 is positioned in a first position, and after passing through the scraping structure, it automatically returns to its unfolded state due to its own elastic restoring force. When the cyclone separating unit is attached to the dust cup 20, the skirt body 2 is pushed as it passes through the scraping structure, and deformed in the direction opposite to the attachment direction of the cyclone separating unit, so that the skirt body 2 is positioned in a second position, and after passing through the scraping structure, it automatically returns to its unfolded state due to its own elastic restoring force.

[0065] The specific operation of the skirt separator device is as follows: In the first situation, when large-sized dirt passes from the cyclone separating chamber to the dirt collecting chamber, the force applied by the dirt to the skirt body 2 causes deformation of the arc-shaped connection formed between the adjacent crushed parts of the skirt body 2. Therefore, deformation occurs at the position of the skirt body 2 that receives the force, allowing the dirt to pass through smoothly.

[0066] In the second situation, in the process of removing the cyclone separating unit 10, specifically, it is determined whether or not the skirt body 2 needs to be folded according to the size of the removal opening of the cyclone separating unit 10.

[0067] When the skirt body 2 fixed to the cyclone separating unit 10 of the scraping device on the dust cup 20 passes, interference occurs, and the arc-shaped connection parts formed between the adjacent crushed parts are deformed and folded under the force.

[0068] When the cyclone separating unit 10 is removed and the size of the opening on the dust cup 20 is large enough, the skirt body 2 can be removed directly without folding it.

[0069] The cleaning device further includes an integrated filter element 90 disposed at the outlet end of the cyclone cone for re-filtering the air separated in the second cyclone separation stage. The integrated filter element 90 is removably disposed within the cyclone separating unit 10, facilitating replacement of the integrated filter element 90. The integrated filter element 90 also further filters the air separated from the second separating unit, reducing impurities in the air discharged to the outside and improving dust collection efficiency.
