Description

Technical Field

[0001] This invention relates to the field of pet vacuum cleaner technology, specifically to a dust cup structure for a pet vacuum cleaner. Background Technology

[0002] With the improvement of socioeconomic level and the lowering of the threshold for pet ownership, more and more people are starting to keep pets. In the process of keeping pets, cleaning the room has become a problem. Pets with hair, such as cats and dogs, shed hair frequently, which is not easy to collect. In response to the above problems, various vacuum cleaners for pets have appeared on the market. The working structure of most existing vacuum cleaners is detachable. The power part is installed on the main body, and the dust cup used to collect dirt can be detached and installed on the main body. The air inlet and air outlet on the dust cup are connected to the air inlet and air outlet on the main body respectively.

[0003] In the prior art, patent application number CN201910058692.8 discloses a dust cup assembly used in a vacuum cleaner, including: a dust cup body with a cyclone separation chamber inside, and an air inlet and an air outlet formed on the dust cup body; an end cap hinged to the bottom end of the dust cup body to close the dust cleaning port of the dust cup body; a filter installed in the cyclone separation chamber, and the interior of the filter is connected to the air outlet, the lower end of the filter has a guide post extending downward and fitted with an elastic element; a dust ejection mechanism, the lower end of which abuts against the inner side of the end cap, the upper end passing through the guide post and abutting against the elastic element, and the outer periphery of the dust ejection mechanism has cyclone blades, which are used to eject the dust accumulated in the cyclone separation chamber from the dust cup body under the action of the elastic element after the end cap is opened; the technical solution allows the dust to be automatically ejected after the end cap is opened, eliminating the need to manually disassemble the dust cup assembly on the vacuum cleaner for cleaning, thus facilitating cleaning and reassembly.

[0004] While the aforementioned technical solution can achieve one-click emptying of general dirt, its emptying effect is not ideal when there is hair, lint, or dirt accumulation in the dust cup. In its structure, the airflow carries dirt to the top of the dust collection mechanism when passing through the separation chamber. When lighter dirt such as pet hair and lint enters, the dust collection mechanism cannot expel it from the dust cup, requiring manual cleaning or the use of tools, which causes cleaning and maintenance troubles. Moreover, the air inlet channel on the dust cup body is connected to the dust cup cavity, occupying the space defined in the dust cup cavity, affecting the smoothness of the inner wall of the dust cup and the dust cup capacity, resulting in a cumbersome cleaning process, more time spent, and affecting the product's appearance. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a dust cup structure for a pet vacuum cleaner, which has the functions of one-button complete emptying and cleaning of the inner wall of the dust cup cavity.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a dust cup structure for a pet vacuum cleaner, comprising a bottom cover, a dust collection component, a dust cup body, a filter component, and an end cover arranged sequentially from bottom to top; wherein, the end cover is installed on the top of the dust cup body, the interior of the dust cup body forms a storage cavity for collecting dirt, and when the end cover is closed on the top of the dust cup body, a filter cavity for installing the filter component is formed between the end cover and the storage cavity; the storage cavity has an air outlet channel communicating with the filter cavity; the dust collection component is disposed inside the storage cavity, and the dust collection component includes a slidably sleeved on the air outlet channel. The support on the air duct has a storage groove at the top for accommodating the elastomer. A filter and multiple deceleration ribs are arranged sequentially from bottom to top on the windward side of the support, with the deceleration ribs extending downwards through the filter. A bottom cover is movably connected to the bottom of the dust cup body, and has an air inlet and an air outlet. When the bottom cover is closed on the bottom of the dust cup body, the lower end of the air outlet duct communicates with the air outlet, and airflow flows from the air inlet side to the filter assembly side. When the bottom cover detaches from the bottom of the dust cup body, the elastomer drives the support to move along the axial direction of the dust cup body towards the bottom cover.

[0007] In a preferred embodiment of the present invention, the bottom cover is provided with a groove communicating with the air outlet, the bottom cover is provided with a cyclone mouth communicating with the air inlet on one side corresponding to the storage cavity, and a dust baffle that can be flipped is installed on the air outlet side of the cyclone mouth.

[0008] In a preferred embodiment of the present invention, a groove for limiting and guiding the bracket is provided on the outer circumferential surface of the air outlet channel, and a guide post corresponding to the groove is provided on the inner circumferential surface of the bracket.

[0009] In a preferred embodiment of the present invention, the filter assembly includes a filter frame located between the end cap and the air outlet channel. The filter frame has a first filter layer and a second filter layer for removing particulate impurities in the air arranged sequentially from bottom to top inside, and a filter sealing ring for sealing is provided between the filter frame and the end cap.

[0010] In a preferred embodiment of the present invention, an air outlet sealing ring is installed inside the air outlet, a handle is installed on the top of the end cover, and a positioning rib for fixing the filter assembly is provided inside the end cover.

[0011] In a preferred embodiment of the present invention, a scraping soft rubber plate that fits against the inner wall of the dust cup body is sleeved on the outer circumferential surface of the top of the bracket, and the distance between the scraping soft rubber plate and the inner wall of the dust cup body is ±3mm.

[0012] In a preferred embodiment of the present invention, the air outlet channel and the dust cup body are connected by a spoke frame, the upper end of the spoke frame is provided with a plurality of second sealing grooves for installing the second sealing ring, and the lower end of the filter frame presses against the upper end of the second sealing ring.

[0013] In a preferred embodiment of the present invention, a first sealing groove for installing a first sealing ring is provided at the bottom of the spoke frame, and when the bottom cover is closed on the bottom of the dust cup body, the upper end of the elastic body is pressed against the lower end of the first sealing ring.

[0014] In a preferred embodiment of the present invention, one side of the bottom cover is hinged to the bottom of the dust cup body, and the other side of the bottom cover is detachably connected to the dust cup body via a release component, and the release component is disposed on the outside of the dust cup body.

[0015] This invention addresses the shortcomings of the prior art, and its beneficial effects are as follows:

[0016] (1) In this invention, the filter and deceleration ribs can intercept large and light dirt on its windward side and compress the dirt as it flows through the air. When the bottom cover is opened, the elasticity of the elastic body drives the bracket to provide initial kinetic energy for the compressed dirt, so that the dirt can be completely discharged from the collection cavity under its own weight and initial kinetic energy. This structure can solve the problem that existing dust cup structures cannot completely empty hair and other lint-like dirt, thereby improving the efficiency of one-click emptying of dirt.

[0017] (2) The aforementioned deceleration ribs can not only intercept lint and other fibrous dirt, but also support the compressed dirt away from the surface of the filter screen, thereby ensuring that the air inlet side of the filter screen always has a certain air passage section, so as to ensure that the airflow can pass smoothly.

[0018] (3) In this invention, by setting the air inlet and air outlet on the bottom cover, the smoothness of the inner wall of the dust cup body can be ensured, and the scraping soft rubber plate that is in contact with the inner wall of the dust cup body can move down with the release of the dust ejection component, using the potential energy of the downward movement of the support, so as to scrape and clean the dirt attached to the inner wall of the dust cup body, thereby promoting the cleaning efficiency of the dust cup body.

[0019] (4) In this invention, the sliding distance of the ash-spraying component can be limited and its direction can be guided by the cooperation between the guide post and the slide groove, so as to prevent it from leaving the air outlet channel during the downward movement.

[0020] (5) In this invention, the filter screen can be used to filter the dirt entering the storage cavity once, and the first filter layer and the second filter layer in the filter assembly can be used to filter the airflow twice and three times respectively, thereby ensuring the cleanliness of the exhaust air and extending the service life of the main unit.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention and therefore only show the components relevant to the present invention.

[0028] like Figure 1As shown, a dust cup structure for a pet vacuum cleaner includes, from bottom to top, a bottom cover 3, a dust collection component 50, a dust cup body 1, a filter component 40, and an end cover 2. The end cover 2 is connected to the dust cup body 1 by a snap-fit ​​mechanism. Specifically, the end cover 2 has a corresponding slot, and the dust cup body 1 has a snap-fit ​​mechanism. After the slot on the end cover 2 aligns with the snap-fit ​​mechanism, rotating the end cover 2 in a certain direction will achieve the snap-fit ​​connection. The bottom cover 3 is movably connected to the bottom of the dust cup body 1 and can be released with a single button via a release component. After release, there is at least one connection point between the bottom cover 3 and the dust cup body 1, and a sealing ring is installed on the bottom cover 3 to ensure the airtightness of the storage cavity 9 after the bottom cover 3 and the dust cup body 1 are closed.

[0029] The end cap 2 is installed on the top of the dust cup body 1. A handle 11 is installed on the top of the end cap 2, and a positioning rib 21 for fixing the filter assembly 40 is provided inside the end cap 2. The handle 11 facilitates the installation and removal of the end cap 2. After the end cap 2 is closed, the positioning rib 21 can support and limit the filter frame 44 of the filter assembly 40 to prevent the filter assembly 40 from shifting due to airflow, thereby ensuring the sealing and filtration effect of the assembly.

[0030] like Figure 1 , 3 As shown in Figure 4, when the end cap 2 is closed on the top of the dust cup body 1, a filter chamber for installing the filter assembly 40 is formed between it and the receiving cavity 9. An air outlet channel 80 communicating with the filter chamber is provided inside the receiving cavity 9. The air outlet channel 80 is connected to the dust cup body 1 via a spoke bracket 85. The filter chamber is mainly used to install the filter assembly 40, and the filter assembly 40 has a through hole coaxial with the air outlet channel 80 inside, to ensure that the airflow entering the receiving cavity 9 can smoothly enter the air outlet channel 80 after passing through the filter assembly 40.

[0031] As described above, the upper end of the spoke frame 85 is provided with multiple second sealing grooves 83 for installing the second sealing ring 84, and the bottom of the spoke frame 85 is provided with a first sealing groove 82 for installing the first sealing ring 58. The spoke frame 85 has a ring-shaped hollow design, which can connect the air outlet channel 80 and the dust cup body 1 while ensuring smooth airflow. The upper and lower ends of the spoke frame 85 are respectively provided with the second sealing ring 84 and the first sealing ring 58. When the end cover 2 is installed on the dust cup body 1, the lower end of the filter frame 44 presses against the upper end of the second sealing ring 84 to ensure the sealing between the lower end of the filter assembly 40 and the air outlet channel 80. When the bottom cover 3 is closed on the bottom of the dust cup body 1, the upper end of the elastic body 57 presses against the lower end of the first sealing ring 58 to ensure the sealing between the receiving cavity 9 and the air outlet channel 80.

[0032] like Figure 1-3As shown, the bracket 51 of the dust collection component 50 is sleeved on the air outlet duct 80. The top of the bracket 51 is provided with a storage groove 56 for storing the elastomer 57. The outer circumferential surface of the top of the bracket 51 is fitted with a dust scraping soft rubber plate 53 that fits against the inner wall of the dust cup body 1. Specifically, when the bottom cover 3 is closed, the lower end of the bracket 51 abuts against the bottom cover 3. At this time, the elastic body 57 is compressed and stores a certain elastic potential energy, and contracts inside the storage groove 56. When the bottom cover 3 is opened, under the action of the elastic force of the elastic body 57, the bracket 51 is driven to move down along the air outlet channel 80 to push the compressed dirt stored in the storage cavity 9, provide it with initial kinetic energy, and under its own gravity, it is separated from the storage cavity 9. During the reciprocating movement of the bracket 51, the guide post 55 on the bracket 51 slides in the groove 81 outside the air outlet channel 80 to achieve the purpose of limiting and guiding. Among them, the elastic body 57 is preferably a helical spring. The scraper rubber plate 53 can clean the inner wall of the dust cup body 1 as the bracket 51 moves down, and the distance between the scraper rubber plate 53 and the inner wall of the dust cup body 1 can be set to ±3mm.

[0033] As described above, the windward side of the bracket 51 is provided with a filter screen 59 and multiple deceleration ribs 54 from bottom to top, with the deceleration ribs 54 extending downward through the filter screen 59. The filter 59 is located on the windward side of the bracket 51 and can be made of metal. A slot corresponding to the deceleration rib 54 can be formed on the filter 59 so that the deceleration rib 54 can pass through the filter 59. The metal filter 59 is positioned on the windward side to perform the initial filtration of inhaled hair, dust, and other dirt. As small debris such as hair, lint, and dust are continuously drawn in, they are pulled by the upward airflow and, under the resistance of the deceleration rib 54, accumulate. As the airflow continues to pass through, the dirt is compressed. Simultaneously, the deceleration rib 54 also supports the compressed dirt away from the surface of the filter 59, ensuring that the air inlet side of the filter 59 always has a certain cross-section for airflow, ensuring smooth airflow. This improves the dirt compression effect and the effective volume of the collection chamber 9 while preventing the main unit from overheating and shutting down or malfunctioning due to obstructed airflow.

[0034] like Figure 2As shown, the filter assembly 40 includes a filter frame 44 located between the end cap 2 and the air outlet channel 80. Inside the filter frame 44, from bottom to top, are a first filter layer 41 and a second filter layer 42 for removing particulate impurities from the air. The first filter layer 41 can be made of composite filter cotton, and the second filter layer 42 can be made of HEPA material, a high-efficiency filter paper mainly used in vacuum cleaner filtration designs, capable of filtering up to 99% of fine particles. When airflow passes through the first filter layer 41 and the second filter layer 42 from bottom to top, the impurities carried within are filtered twice and remain in the filter chamber. The filtered air is then discharged from the air outlet along the air outlet channel 80. Additionally, a filter sealing ring 43 is provided between the filter frame 44 and the end cap 2 for sealing.

[0035] like Figure 1-2 As shown, the bottom cover 3 has an air outlet and an air inlet 6 that communicates with the storage cavity 9. The bottom cover 3 has a groove that communicates with the air outlet, and an air outlet sealing ring 10 is installed inside the air outlet. Both the air inlet 6 and the air outlet are located on the bottom cover 3, which can increase the volume of the storage cavity 9 while ensuring that the inner wall of the dust cup body 1 is smooth. The air inlet 6 and the air outlet are respectively connected to the corresponding interfaces of the main unit to ensure that the airflow can pass smoothly through the storage cavity 9. The groove facilitates the quick installation of the dust cup structure on the main unit, which satisfies the positioning conditions and improves the disassembly and assembly speed. The air outlet sealing ring 10 is mainly used to ensure the sealing between the bottom cover 3 and the air outlet channel 80. When the bottom cover 3 is closed on the bottom of the dust cup body 1, the lower end of the air outlet channel 80 is connected to the air outlet.

[0036] The bottom cover 3 is provided with a cyclone 70 connected to the air inlet 6 on one side of the storage cavity 9, and a dust baffle 71 that can be flipped is installed on the air outlet side of the cyclone 70. Dirt is drawn into the air duct of the main body by the dust suction component, and enters the cyclone inlet 70 through the air inlet 6. At this time, the dust baffle 71 is pushed open by the airflow, and the dirt enters the collection chamber 9. Due to the airflow and the angle of the cyclone inlet 70, the dirt is thrown out from the cyclone inlet 70 along the inner wall of the dust cup body 1. The larger dirt is eventually settled above the bottom cover 3 by the centrifugal force and gravity, while the smaller dirt such as hair, lint, and dust is pulled up to the windward side of the filter 59 below the dust ejector assembly 50 by the centrifugal force and the upward airflow. The smaller hair and lint are gradually stopped by the resistance of the deceleration ribs 54 arranged on the bracket 51 and accumulate here. The filter 59 performs the first filtration, and one end of the dust baffle 71 can be rotatably connected to the cyclone inlet 70. A corresponding torsion spring is set at the rotatable connection to ensure that the dust baffle 71 can close in time after the machine stops, so that the collection chamber 9 becomes a sealed chamber and prevents dirt from flowing out.

[0037] One side of the bottom cover 3 is rotatably connected to the dust cup body 1, and the other side of the bottom cover 3 is detachably connected to the dust cup body 1 via a release assembly, which is located on the outside of the dust cup body 1. Specifically, a pivot 31 is provided at the rotatable connection between the bottom cover 3 and the dust cup body 1, and a release assembly is provided on the other side. The release assembly consists of a fastener 32 and a return spring 33. The fastener 32 is hinged to the outside of the dust cup body 1, and one end of the fastener 32 is provided with a hook for engaging the bottom cover 3. The bottom cover 3 is provided with a protrusion corresponding to the hook, and the return spring 33 is located on the side opposite to the hook between the fastener 32 and the dust cup body 1. When one end of the fastener 32 is pressed down to compress the return spring 33, the hook disengages from the protrusion, and the bottom cover 3 is released. Conversely, when the bottom cover 3 is closed, the return spring 33 can drive the fastener 32 to rotate, causing its hook to engage with the protrusion, thereby fixing the bottom cover 3.

[0038] The working principle of cleaning the receiving cavity 9 using the above-disclosed technical solution is as follows:

[0039] Normal operating state: At this time, the dust cup body 1 and the bottom cover 3 are in the closed state. The dust ejector component 50 is close to the filter component 40 and is pressed together with the sealing ring to form an effective seal. The air inlet 6 on the bottom cover 3 is sealed and connected to the main body. Dirt is sucked into the air duct of the main body by the dust suction component. The air inlet 6 enters the cyclone inlet 70. At this time, the dust baffle 71 is pushed open by the airflow, and the dirt enters the collection chamber 9. Due to the airflow and the angle of the cyclone inlet 70, the dirt is thrown out along the inner wall of the dust cup body 1 through the cyclone inlet 70. Larger debris eventually settles to the bottom cover due to centrifugal force and gravity. Above the filter 59, small debris such as hair, lint, and dust rises to the ground under the filter 59 due to centrifugal force and upward airflow. The small hair and lint gradually stop moving due to the resistance of the deceleration ribs 54 on the support 51, accumulating there and achieving the first filtration. The dirt mixed with fine particles and hair passes sequentially through the first filter layer 41 and the second filter layer 42 of the filter assembly 40 under the influence of airflow, achieving the second and third filtrations. The filtered clean air enters the main unit's air outlet duct through the air outlet 80 and the air outlet, and is finally discharged into the room. When the main unit stops working, the dust baffle 71 on one side of the cyclone outlet 70 closes, forming a sealed cavity in the dust cup body 1. The user can disassemble it from the main unit for emptying or cleaning.

[0040] Dust cup assembly tilted state: The user holds the handle 11 with one hand and presses the release assembly with the other. The return spring 33 on one side of the fastener 32 is compressed by the pressing pressure. The fastener 32 flips at a certain angle, causing the protrusion of the bottom cover 3 to disengage from the hook. Under the action of gravity, the bottom cover 3 flips at a certain angle, creating a gap between itself and the lower end face of the dust collection assembly 50. At this time, the elastic body 57 inside the dust collection assembly 50 deforms, applying a spring force to the dust collection assembly 50 axially outward towards the storage cavity 9. Under the action of gravity and the spring force of the dust collection assembly 50, the bottom cover 3 continues to flip downward. As the filter 59 rotates, the dirt that has been gathered or compressed on the windward side is pushed down a certain distance by the dust collection assembly 50 under the elastic potential energy. Then, the guide post 55 of the dust collection assembly 50 stops sliding due to the resistance of the limiting groove 81 on the outside of the air outlet channel 80. The dirt accelerates downward under the combined action of inertia and gravity until it falls outside the collection cavity 9. The scraper rubber plate 53 stays in contact with the inner wall of the dust cup body 1 from the starting point of the movement to the position where it stops due to resistance, removing the dirt remaining on its inner wall.

[0041] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
