A sweeper capable of adjusting suction and a method of using the same

Abstract

This invention discloses a sweeping machine with adjustable suction power and its usage method. It includes a sweeping machine body, a dust box and a suction component fixed to the base of the sweeping machine body, a cover for sealing the dust box opening installed at the bottom of the base, an air inlet slot at the bottom of the suction component, and a ventilation duct inside the suction component, with both ends of the ventilation duct connected to the air inlet slot and the dust box, respectively. Starting the motor causes the screw to rotate, which in turn moves the threaded block, horizontal bar, and vertical bar, thereby moving the long rod and baffle. When the baffle no longer seals the groove, the long rod moves within the inclined groove and presses against the inclined plate, thus moving the inclined plate, straight plate, and rectangular plate. When the rectangular plate moves, it causes a wedge plate to move from the inner cavity into the ventilation duct, thereby reducing the ventilation space of the ventilation duct. Since the inclined surface of the wedge plate descends with the wind direction, it increases the wind speed passing through it, thus increasing the suction power.

Description

Technical Field

[0001] This invention relates to the field of sweeping machine technology, and in particular to a sweeping machine with adjustable suction power and its usage method. Background Technology

[0002] Robotic vacuum cleaners, also known as automatic cleaning machines, smart vacuums, or robotic vacuums, are a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. They typically use a combination of brushing and vacuuming to collect debris into their dustbin, thus completing the cleaning process.

[0003] Existing robotic vacuum cleaners can smoothly complete the cleaning work when dealing with ordinary floors. However, in some special cases, such as cleaning dust and hair in carpet fibers, stronger suction is required. Since the air intake channel of existing robotic vacuum cleaners is usually fixed, increasing suction power is mainly achieved by increasing the power of the fan. However, with the increase in fan power, the noise of the fan increases, causing noise pollution. Furthermore, the increased fan power will inevitably make it consume more electricity, which not only wastes electricity but also shortens its working time, requiring frequent charging. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a sweeper with adjustable suction power and its usage method. The technical problem to be solved is that existing sweepers mainly increase suction power by increasing the power of the fan. However, increasing the power of the fan increases the noise of the fan and also inevitably makes it consume more electricity.

[0005] To achieve the above-mentioned technical objectives, the present invention provides a sweeper capable of adjusting suction power: It includes a sweeper body, on which a dust box and a suction component are fixed. A cover for sealing the dust box opening is installed at the bottom of the sweeper body base. An air inlet slot is opened at the bottom of the suction component. A ventilation duct is opened inside the suction component, and both ends of the ventilation duct are connected to the air inlet slot and the dust box, respectively. An air hole connected to the air inlet slot is opened at the bottom of the sweeper body base. Two grooves are opened inside the suction component, and the grooves are connected to the ventilation duct. Two inner cavities are opened in the middle of the suction component, and the inner cavities are connected to the grooves. A wedge plate is slidably connected inside the inner cavity. A drive component is provided on the suction component for driving the wedge plate to move inside the inner cavity.

[0006] As a preferred embodiment of the sweeper capable of adjusting suction power according to the present invention, the suction component has two first stroke grooves, and the first stroke grooves are connected to the groove. A baffle for sealing the groove is slidably connected in the first stroke groove.

[0007] As a preferred embodiment of the sweeping machine capable of adjusting suction power according to the present invention, the suction component has two second stroke grooves, and the second stroke grooves are connected to the inner cavity. The top of the suction component is provided with a rectangular plate connected to it, and the bottom of the rectangular plate is fixed with a connecting plate. The bottom of the connecting plate is fixed to a wedge plate, and the connecting plate is slidably fitted in the second stroke groove.

[0008] As a preferred embodiment of the sweeping machine capable of adjusting suction power according to the present invention, the driving assembly includes a straight plate fixed to one side of a rectangular plate, an inclined plate fixed to one end of the straight plate, a straight groove formed in the straight plate, an inclined groove formed in the inclined plate, and the straight groove and the inclined groove are connected to each other. A long rod is fixed to the top of the baffle, and the long rod is slidably engaged in the first stroke groove, the straight groove, and the inclined groove.

[0009] As a preferred embodiment of the sweeper capable of adjusting suction power according to the present invention, the top of the suction component is fixed with two U-shaped limiting plates, the rectangular plate is slidably fitted within the corresponding U-shaped limiting plates, a connecting block is fixed on the side of the straight plate away from the rectangular plate, and a triangular pressure plate is fixed on one side of the connecting block.

[0010] As a preferred embodiment of the sweeper capable of adjusting suction power according to the present invention, wherein: a vertical rod is fixed on the long rod, a horizontal rod is fixed between the two vertical rods, and a threaded block is fixed in the middle of the horizontal rod.

[0011] As a preferred embodiment of the sweeping machine capable of adjusting suction power according to the present invention, the suction component has two ear plates fixed on it, and a screw is rotatably connected between the two ear plates. The screw passes through a threaded block and is threadedly connected to the threaded block. A motor is installed on one of the ear plates, and one end of the screw is fixed to the output end of the motor.

[0012] As a preferred embodiment of the sweeper capable of adjusting suction power according to the present invention, the suction component has a chamber that is connected to a ventilation duct. A stop block is slidably connected inside the chamber. Two connecting columns are fixed on the top of the stop block. The connecting columns pass through the suction component and slide inside the suction component.

[0013] As a preferred embodiment of the sweeping machine capable of adjusting suction power according to the present invention, a ball is fixed at the top of the connecting column, an elastic element is sleeved on the outside of the connecting column, one end of the elastic element abuts against the ball, and the other end of the elastic element abuts against the suction element.

[0014] The present invention also provides a method of using a sweeping machine, which employs the above-mentioned sweeping machine with adjustable suction power, including the following steps: Step 1: When the suction power of the sweeper needs to be adjusted, start the motor to make the screw rotate. When the screw rotates, it drives the threaded block, the horizontal bar, and the vertical bar to move. When the vertical bar moves, it drives the long bar to move in the straight groove. At this time, when the long bar moves, it drives the baffle to move into the first stroke groove. When the long bar moves to the junction of the straight groove and the oblique groove, the baffle no longer seals the groove. Step 2: As the horizontal and vertical bars continue to move, the long bar will move into the inclined groove and slide within it. At this time, the long bar will press against the inclined plate and drive it to move. When the inclined plate moves, it will drive the straight plate and rectangular plate to move. When the rectangular plate moves, it will drive the connecting plate and wedge plate to move, so that the inclined surface of the wedge plate moves from the inner cavity into the ventilation duct. Step 3: When the straight plate moves, it will also drive the connecting block and the triangular pressure plate to move. When the triangular pressure plate approaches the ball, it will squeeze the ball and drive the ball, connecting column and stop block to move down, so that the bottom of the stop block and the top of the wedge plate are in contact. At this time, the wedge plate and the stop block will reduce the ventilation space of the ventilation duct, thereby increasing the suction.

[0015] As can be seen from the above technical solutions, this application has the following beneficial effects: 1. Start the motor to drive the screw to rotate. The rotation of the screw drives the threaded block, horizontal bar, and vertical bar to move, which in turn drives the long bar and baffle to move. When the baffle no longer seals the groove, the long bar will move in the inclined groove and squeeze the inclined plate, thereby driving the inclined plate, straight plate, and rectangular plate to move. When the rectangular plate moves, it drives the wedge plate to move from the inner cavity into the ventilation duct, thereby reducing the ventilation space of the ventilation duct. Since the inclined surface of the wedge plate tends to descend with the wind direction, it can increase the wind speed passing through it, thereby increasing the suction.

[0016] 2: When the rectangular plate and straight plate move, they will also drive the connecting block and the triangular pressure plate to move. When the triangular pressure plate squeezes the ball and drives the connecting column and the stop block to move down, the bottom of the stop block and the top of the wedge plate will fit together. The cooperation between the stop block and the wedge plate will reduce the ventilation space of the ventilation duct and further enhance the suction.

[0017] 3: When the long rod moves from the straight groove to the inclined groove, it will cause the baffle to move so that it no longer seals the groove. Then, the wedge plate will move from the inner cavity to the ventilation channel, thereby increasing the suction. When the long rod moves from the inclined groove to the straight groove, the wedge plate will first move to the inner cavity, and then the baffle will seal the groove again, which can prevent dust and other impurities from falling into the inner cavity. That is, during the process of the long rod moving from the straight groove to the inclined groove, the baffle will no longer seal the groove and the wedge plate will move to the ventilation channel. During the process of the long rod moving from the inclined groove to the straight groove, the baffle will seal the groove and the wedge plate will move to the inner cavity. The movement of the baffle and the wedge plate is driven by the same force and does not interfere with each other. Attached Figure Description

[0020] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0021] Reference Figure 1-9 : Example 1 This invention provides a sweeper with adjustable suction power, including a sweeper body 1, a dust box 2 and a suction component 4 fixed on the base of the sweeper body 1, a cover 3 for sealing the opening of the dust box 2 installed at the bottom of the base of the sweeper body 1, an air inlet groove 5 at the bottom of the suction component 4, a ventilation channel 7 inside the suction component 4, and both ends of the ventilation channel 7 are respectively connected to the air inlet groove 5 and the dust box 2, an air hole 6 connected to the air inlet groove 5 at the bottom of the base of the sweeper body 1, two grooves 8 inside the suction component 4, and the grooves 8 are connected to the ventilation channel 7, two inner cavities 12 in the middle of the suction component 4, and the inner cavities 12 are connected to the grooves 8, a wedge plate 13 is slidably connected in the inner cavity 12, and a driving component is provided on the suction component 4 for driving the wedge plate 13 to move in the inner cavity 12.

[0022] It should be noted that the vertical cross-section of the inclined surface of the wedge plate 13 has a downward trend from the air inlet slot 5 towards the ventilation duct 7, so that when air passes through the ventilation duct 7 (the airflow direction is as follows)... Figure 7 As indicated by f in the middle), the wedge plate 13 and the baffle 29 compress the ventilation space of the ventilation duct 7, and since the inclined surface of the wedge plate 13 tends to descend with the wind direction, it can increase the wind speed passing through it, thereby increasing the suction.

[0023] The suction component 4 has a chamber 28 inside, and the chamber 28 is connected to the ventilation duct 7. A baffle 29 is slidably connected inside the chamber 28. Two connecting posts 30 are fixed on the top of the baffle 29. The connecting posts 30 pass through the suction component 4 and slide inside the suction component 4. A ball 31 is fixed on the top of the connecting post 30. An elastic member 32 is sleeved on the outside of the connecting post 30. One end of the elastic member 32 abuts against the ball 31, and the other end of the elastic member 32 abuts against the suction component 4.

[0024] In addition, the suction component 4 has two first stroke grooves 9, which are connected to the groove 8. A baffle 10 for sealing the groove 8 is slidably connected in the first stroke groove 9. The suction component 4 has two second stroke grooves 11, which are connected to the inner cavity 12. A rectangular plate 15 is connected to the top of the suction component 4, and a connecting plate 14 is fixed to the bottom of the rectangular plate 15. The bottom of the connecting plate 14 is fixed to the wedge plate 13, and the connecting plate 14 is slidably fitted in the second stroke groove 11.

[0025] Furthermore, the drive assembly includes a straight plate 17 fixed to one side of the rectangular plate 15, with an inclined plate 18 fixed to one end of the straight plate 17. A straight groove 19 is formed inside the straight plate 17, and an inclined groove 20 is formed inside the inclined plate 18. The straight groove 19 and the inclined groove 20 are connected. A long rod 21 is fixed to the top of the baffle 10, and the long rod 21 slides within the first stroke groove 9, the straight groove 19, and the inclined groove 20. Two U-shaped limiting plates 16 are fixed to the top of the suction component 4, and the rectangular plate 15 slides within the corresponding U-shaped limiting plates 16. The straight plate 17 is further... A connecting block 33 is fixed to one side of the rectangular plate 15, and a triangular pressure plate 34 is fixed to one side of the connecting block 33. A vertical rod 22 is fixed to the long rod 21, and a horizontal rod 23 is fixed between the two vertical rods 22. A threaded block 26 is fixed in the middle of the horizontal rod 23. Two ear plates 24 are fixed to the suction component 4, and a screw 25 is rotatably connected between the two ear plates 24. The screw 25 passes through the threaded block 26 and is threadedly connected to the threaded block 26. A motor 27 is installed on one of the ear plates 24, and one end of the screw 25 is fixed to the output end of the motor 27.

[0026] It should be noted that the elastic element 32 can use a spring or other device, and in its normal state, the stop 29 is located inside the chamber 28, and the bottom of the stop 29 and the top inner wall of the ventilation duct 7 are on the same horizontal plane. When the ball 31 is squeezed by the triangular pressure plate 34, the ball 31 will move down and drive the stop 29 down. When the bottom of the stop 29 and the top of the wedge plate 13 are in contact, the top of the stop 29 is still located inside the chamber 28, so that the top of the stop 29 still seals the chamber 28. At this time, the stop 29 and the wedge plate 13 reduce the ventilation space of the ventilation duct 7, thereby increasing the suction.

[0027] In use, when the motor 27 is started, it drives the screw 25 to rotate, which in turn drives the threaded block 26, the horizontal bar 23, and the vertical bar 22 to move. When the vertical bar 22 moves, it drives the long bar 21 to slide in the straight groove 19. At this time, the long bar 21 drives the baffle 10 to move into the first stroke groove 9. When the baffle 10 no longer seals the groove 8, the baffle 10 continues to move in the first stroke groove 9. Meanwhile, the long bar 21 moves in the inclined groove 20 and squeezes the inclined plate 18, thereby driving the inclined plate 18, the straight plate 17, and the rectangular plate 15 to move. When the rectangular plate 15 moves, it drives the wedge plate 13 to move through the connecting plate 14. That is, the wedge plate 13 moves from the inner cavity 12 into the ventilation duct 7, thereby reducing the ventilation space of the ventilation duct 7. When the rectangular plate 15 and the straight plate 17 move, they also drive the connecting block 33 and the triangular pressure plate 34 to move. When the triangular pressure plate 34 squeezes the ball 31, it causes the connecting column 30 and the stop block 29 to move down, so that the stop block 29 and the wedge plate 13 cooperate to reduce the ventilation space of the ventilation duct 7, thereby increasing the suction. When the screw 25 rotates in the opposite direction, the long rod 21 moves from the inclined groove 20 into the straight groove 19, which drives the inclined plate 18, the straight plate 17, and the rectangular plate 15 to move in the opposite direction, thereby driving the wedge plate 13 to move into the inner cavity 12. After that, when the long rod 21 moves in the straight groove 19, the inclined plate 18, the straight plate 17, and the rectangular plate 15 will no longer move. That is, the wedge plate 13 will not move after it moves into the inner cavity 12. After that, when the long rod 21 continues to move in the straight groove 19, it will drive the baffle 10 to seal the groove 8, thereby preventing dust and other impurities from falling into the inner cavity 12.

[0028] Example 2 Based on Embodiment 1, this invention provides a method for using a sweeping machine, including the following steps: Step 1: When the suction power of the sweeper needs to be adjusted, start the motor 27 to drive the screw 25 to rotate. When the screw 25 rotates, it drives the threaded block 26, the horizontal bar 23, and the vertical bar 22 to move. When the vertical bar 22 moves, it drives the long bar 21 to move in the straight groove 19. At this time, when the long bar 21 moves, it drives the baffle 10 to move into the first stroke groove 9. When the long bar 21 moves to the junction of the straight groove 19 and the oblique groove 20, the baffle 10 no longer seals the groove 8. Step 2: As the horizontal bar 23 and vertical bar 22 continue to move, the long bar 21 will move into the inclined groove 20 and slide within it. At this time, the long bar 21 will press the inclined plate 18 and drive it to move. When the inclined plate 18 moves, it will drive the straight plate 17 and rectangular plate 15 to move. When the rectangular plate 15 moves, it will drive the connecting plate 14 and wedge plate 13 to move, so that the inclined surface of the wedge plate 13 moves from the inner cavity 12 into the ventilation duct 7. Step 3: When the straight plate 17 moves, it will also drive the connecting block 33 and the triangular pressure plate 34 to move. When the triangular pressure plate 34 approaches the ball 31, it will squeeze the ball 31 and drive the ball 31, the connecting column 30, and the stop block 29 to move down, so that the bottom of the stop block 29 and the top of the wedge plate 13 fit together. At this time, the wedge plate 13 and the stop block 29 reduce the ventilation space of the ventilation duct 7, thereby increasing the suction.
