Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner technology, and more specifically, to a flat suction structure with a light. Background Technology

[0002] Handheld vacuum cleaners, a common household cleaning tool, are small in size, making them very convenient to carry and use, and are particularly suitable for cleaning smaller spaces. Handheld vacuum cleaners need to be connected to a crevice tool to operate, using the crevice tool to suck dust into the vacuum cleaner.

[0003] like Figure 17 The aforementioned is a pre-existing illuminated flat nozzle structure, comprising: a flat nozzle, a flat nozzle cover, a flat nozzle bracket, a button, a PCB, and an LED light. The LED light is installed on the flat nozzle to improve its cleaning ability in shadowy corners. This structure is simple, efficient, and inexpensive.

[0004] However, existing flat nozzle structures with lights are mostly integrated designs. To facilitate cleaning of crevices and corners, their flat nozzle channels are narrow. However, narrow flat nozzle channels are prone to blockage, making cleaning inconvenient and affecting the normal use of the vacuum cleaner. At the same time, the integrated flat nozzle design takes up a large area and is inconvenient to carry. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a flat suction cup structure with an integrated light. By controlling the two extended flat suction cups to slide along the guide, they unfold or retract on their own, while simultaneously causing the upper and lower flat suction cups to close or separate. When the two extended flat suction cups are in the retracted state, the upper and lower flat suction cups are separated, facilitating cleaning of the interior of the upper and lower flat suction cups and making them easy to carry.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A flat suction device with an integrated light includes a connecting frame screwed into the suction end of a vacuum cleaner; the connecting frame includes a mounting shell; a support frame is fixedly installed inside the mounting shell; an upper flat suction component and a lower flat suction component are symmetrically slidably arranged on the support frame and interlocked with each other; both the upper and lower flat suction components are slidably engaged with the inner wall of the mounting shell; guide components are symmetrically fixed on the side of the mounting shell; extended flat suction components adapted to the guide components are slidably arranged on both the upper and lower flat suction components; a rubber sleeve is sleeved between the two extended flat suction components in the closed state; a fixing frame adapted to the rubber sleeve is fixed to the end of the rubber sleeve; a PCB box for mounting a PCB is mounted on the surface of the fixing frame; an LED light is electrically connected to the output end of the PCB box.

[0009] The invention is further configured such that: a screw is threaded through the periphery of the semi-connecting pipe; a connector is fixed at one end of the screw, and a square rod is rotatably provided at the other end; the support frame includes a vertical rod fixedly installed between the inner walls of the suction pipe; an extension rod is fixed to the side of the vertical rod; a sleeve that slides with the square rod is fixed to the end of the extension rod; and baffles are fixed to both ends of the sleeve.

[0010] The invention is further configured such that: the side of the semi-inner flat straw has symmetrically opened sliding grooves; the extended flat straw includes a semi-outer flat straw; the interior of the semi-outer flat straw has a sliding cavity that slides and engages with the corresponding semi-inner flat straw; and the inner wall of the sliding cavity is symmetrically fixed with a slide rail that slides and engages with the corresponding sliding groove.

[0011] The present invention is further configured such that: the guide member includes two Z-shaped plates arranged symmetrically; a Z-shaped guide groove is formed inside the Z-shaped plate; the Z-shaped guide groove includes a first straight guide groove and a second straight guide groove arranged parallel to each other; an oblique guide groove is formed between the first straight guide groove and the second straight guide groove.

[0012] The present invention is further configured such that: ear plates are symmetrically fixed on opposite sides of the semi-flat straw; a sliding rod is fixed on the side of the ear plate; and the sliding rod is slidably engaged with the first straight guide groove, the second straight guide groove, and the oblique guide groove respectively.

[0013] The invention is further configured such that: a piston cylinder is fixedly installed at the end of one set of Z-shaped plates in the same guide member, and an inclined guide plate is slidably disposed through the surface of another set of Z-shaped plates; a cover plate adapted to the slide rod is fixedly fixed on the surface of the inclined guide plate; and a return spring is fixedly connected between the cover plate and the corresponding Z-shaped plate surface.

[0014] The invention is further configured as follows: a piston block is slidably disposed inside the piston cylinder; a piston rod is fixed to the side of the piston block and slidably cooperates with the piston cylinder; a connecting spring sleeved on the piston rod is fixedly connected between the piston block and the piston cylinder; an air extraction branch pipe is connected to the end of the piston cylinder, and an exhaust branch pipe is connected to its peripheral side near its end; a sealing cap is screwed onto the air extraction branch pipe; the sealing plate has a hollow internal structure, and installation ports are opened on both opposite sides; an elastic diaphragm is disposed inside the installation port; sealing cavities adapted to the elastic diaphragm in the inflated state are symmetrically opened on both sides of the inner wall of the sealing groove; an air supply pipe communicating with the corresponding sealing plate is fixedly disposed through the outer wall of the semi-connecting pipe; the air supply pipe and the exhaust branch pipe are connected by a flexible hose.

[0016] The advantages of this invention are: 1. This invention controls the two extended flat suction tubes to unfold or retract themselves as they slide along the guide, while simultaneously causing the upper and lower flat suction tubes to close or separate. When the two extended flat suction tubes are in the retracted state, the upper and lower flat suction tubes separate, which facilitates cleaning the inside of the upper and lower flat suction tubes and makes them easy to carry.

[0017] 2. In this invention, as the sliding rod slides inside the second straight guide groove, it slides and squeezes the corresponding piston rod, thereby driving the piston block to slide along the inner wall of the piston cylinder. The connecting spring is stretched, thereby sending the air inside the piston cylinder into the sealing plate through the exhaust branch pipe, hose, and air supply pipe in sequence. The air pressure inside the sealing plate increases, causing the elastic diaphragm to inflate and expand, blocking the sealing cavity and improving the sealing performance of the connection between the upper and lower flat suction parts.

[0018] 3. The present invention improves the sealing performance between the two halves of the outer flat straw in the closed state by placing a rubber sleeve on the two halves of the outer flat straw. This is achieved by attaching a rubber sleeve to the two halves of the outer flat straw in the closed state and then securing the rubber sealing ring to the two halves of the outer flat straw with a strap.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0040] Example 1, please refer to Figure 1-17 The present invention provides the following technical solutions: A flat suction structure with an integrated light, specifically, includes a connecting frame 1 screwed into the suction end of a vacuum cleaner; the connecting frame 1 includes a mounting shell 2; a support frame 3 is fixedly installed inside the mounting shell 2; an upper flat suction component 4 and a lower flat suction component 5 are symmetrically slidably arranged on the support frame 3 and interlocked with each other; both the upper flat suction component 4 and the lower flat suction component 5 are slidably engaged with the inner wall of the mounting shell 2; guide components 6 are symmetrically fixed on the side of the mounting shell 2; both the upper flat suction component 4 and the lower flat suction component 5 are slidably arranged with extension flat suction components 7 adapted to the guide components 6; a rubber sleeve 8 is sleeved between the two extension flat suction components 7 in the closed state; a fixing frame 9 adapted to the rubber sleeve 8 is fixed to the end of the rubber sleeve 8; a PCB box 10 for mounting a PCB is installed on the surface of the fixing frame 9; an LED light 11 is electrically connected to the output end of the PCB box 10.

[0041] Working principle of this embodiment: The upper flat suction component 4 and the lower flat suction component 5 are slidably engaged with the corresponding extended flat suction component 7. By pulling the two extended flat suction components 7 along the guide component 6, the upper flat suction component 4 and the lower flat suction component 5 are driven to slide and rise along the support frame 3.

[0042] As the two extended flat suction tubes 7 slide away from the mounting shell 2, under the guidance of the corresponding guide tubes 6, the two extended flat suction tubes 7 slide closer to each other, causing the upper flat suction tube 4 and the lower flat suction tube 5 to slide closer along the support frame 3. When the upper flat suction tube 4 and the lower flat suction tube 5 complete the insertion and closure, the two extended flat suction tubes 7 close and unfold at the same time. As the two extended flat suction tubes 7 slide closer to the mounting shell 2, the two extended flat suction tubes 7 slide away from each other, causing the upper flat suction tube 4 and the lower flat suction tube 5 to slide away along the support frame 3. When the upper flat suction tube 4 and the lower flat suction tube 5 complete the separation, the two extended flat suction tubes 7 unfold and retract at the same time.

[0043] In summary, by controlling the two extended flat suction tubes 7 to slide along the guide tube 6, they unfold or retract themselves, while simultaneously causing the upper flat suction tube 4 and the lower flat suction tube 5 to close or separate. When the two extended flat suction tubes 7 are in the retracted state, the upper flat suction tube 4 and the lower flat suction tube 5 are separated, which facilitates cleaning the inside of the upper flat suction tube 4 and the lower flat suction tube 5, and also makes them easy to carry.

[0044] Example 2, please refer to Figure 1-17 This embodiment 2 is an improvement on the first embodiment as follows: Specifically, an air extraction pipe 12 is fixed through the inner wall of the mounting shell 2; the end of the air extraction pipe 12 is screwed into the suction end of the vacuum cleaner; both the upper flat suction component 4 and the lower flat suction component 5 include a semi-connecting pipe 13 that is adapted to the outer wall of the air extraction pipe 12; a semi-inner flat suction pipe 14 is fixed to the end of the semi-connecting pipe 13.

[0045] The upper flat suction tube 4 has a sealing plate 15 fixed to the side of the semi-inner flat suction tube 14 and the semi-connecting tube 13. The lower flat suction tube 5 has a sealing groove 16 on the side of the semi-inner flat suction tube 14 and the semi-connecting tube 13 that is inserted into and cooperates with the sealing plate 15.

[0046] A screw 17 is threaded through the side of the semi-connecting pipe 13; a connector 18 is fixed to one end of the screw 17, and a square rod 19 is rotatably provided at the other end; the support frame 3 includes a vertical rod 20 fixedly installed between the inner walls of the suction pipe 12; an extension rod 21 is fixed to the side of the vertical rod 20; a sleeve 22 that slides with the square rod 19 is fixed to the end of the extension rod 21; baffles 23 are fixed to both ends of the sleeve 22.

[0047] Insert the square rod 19 into the corresponding sleeve 22, rotate the screw 17 to make it rotate and descend, causing the square rod 19 to slide inside the sleeve 22 until the connector 18 presses against the outer wall of the half connecting tube 13, thus completing the connection between the support frame 3 and the upper flat suction part 4 and the lower flat suction part 5, which is convenient for disassembly and maintenance.

[0048] The semi-inner flat straw 14 has symmetrically opened grooves 24 on its side; the extended flat straw 7 includes a semi-outer flat straw 25; the semi-outer flat straw 25 has a sliding cavity 26 that slides and engages with the corresponding semi-inner flat straw 14 inside; the inner wall of the sliding cavity 26 is symmetrically fixed with a slide rail 27 that slides and engages with the corresponding groove 24.

[0049] The guide member 6 includes two Z-shaped plates 28 arranged symmetrically; a Z-shaped guide groove 29 is provided inside the Z-shaped plate 28; the Z-shaped guide groove 29 includes a first straight guide groove 30 and a second straight guide groove 31 arranged parallel to each other; an oblique guide groove 32 is provided between the first straight guide groove 30 and the second straight guide groove 31.

[0050] The semi-flat straw 25 has ear plates 33 fixed symmetrically on both sides; the ear plates 33 have slide rods 34 fixed on their sides; the slide rods 34 slide in cooperation with the first straight guide groove 30, the second straight guide groove 31 and the oblique guide groove 32 respectively.

[0051] Working principle of this embodiment two: When the slide bar 34 is inside the corresponding first straight guide groove 30, the two halves of the outer flat straw 25 separate from each other, the upper flat suction part 4 and the lower flat suction part 5 separate from each other, and the upper flat suction part 4 and the lower flat suction part 5 are stored in the sliding cavity 26 inside the corresponding half of the outer flat straw 25. At this time, the inside of the two halves of the outer flat straw 25 can be cleaned, reducing the footprint and making it easy to carry.

[0052] Pull the two halves of the outer flat tube 25 away from the mounting shell 2, so that the slide rod 34 slides from the corresponding first straight guide groove 30 into the inclined guide groove 32. During the sliding of the half outer flat tube 25, the slide rod 34 slides inside the inclined guide groove 32, so that the half outer flat tube 25 slides along the inclined guide groove 32 while sliding, so that the two sets of half outer flat tubes 25 slide closer to each other, thereby driving the upper flat suction member 4 and the lower flat suction member 5 to slide closer along the sleeve 22. When the slide rod 34 slides from the inclined guide groove 32 into the second straight guide groove 31, the upper flat suction member 4 and the lower flat suction member 5 complete the insertion and closure, and at the same time, the two halves of the outer flat tube 25 complete the closure.

[0053] As the slide bar 34 slides inside the second straight guide groove 31, the two halves of the outer flat tube 25 slide only along the second straight guide groove 31 without any lifting or lowering action, thus completing the unfolding of the half outer flat tube 25 and extending the service length of the light strip flat tube structure.

[0054] Example 3, please refer to Figure 1-17 This embodiment three is an improvement on the embodiment two. Specifically, a piston cylinder 35 is fixedly installed at the end of one group of Z-shaped plates 28 in the same guide member 6, and an inclined guide plate 36 is slidably disposed through the surface of another group of Z-shaped plates 28; a cover plate 37 adapted to the slide rod 34 is fixed on the surface of the inclined guide plate 36; a return spring 38 is fixedly connected between the cover plate 37 and the corresponding Z-shaped plate 28 surface.

[0055] A piston block 39 is slidably disposed inside the piston cylinder 35; a piston rod 40 is fixed to the side of the piston block 39 and slides with the piston cylinder 35; a connecting spring 41 sleeved on the piston rod 40 is fixedly connected between the piston block 39 and the piston cylinder 35; an air extraction branch pipe 42 is connected to the end of the piston cylinder 35, and an exhaust branch pipe 43 is connected to its peripheral side near its end; a sealing cap is screwed onto the air extraction branch pipe 42; the sealing plate 15 has a hollow internal structure, and installation ports are opened on both opposite sides; an elastic diaphragm 44 is disposed inside the installation port; sealing cavities 45 adapted to the elastic diaphragm 44 in the inflation state are symmetrically opened on both sides of the inner wall of the sealing groove 16; an air supply pipe 50 communicating with the corresponding sealing plate 15 is fixedly disposed through the outer wall of the semi-connecting pipe 13; the air supply pipe 50 and the exhaust branch pipe 43 are connected by a flexible hose.

[0056] The surface of the semi-flat straw 25 is evenly provided with several U-shaped grooves 46; the inner wall of the rubber sleeve 8 is fixed with several rubber sealing rings 47 that are adapted to the corresponding U-shaped grooves 46; the bottom surface of the rubber sleeve 8 is fixed with several straps 48; the sides of the straps 48 are provided with a rough surface layer; the sides of the rubber sleeve 8 are provided with a hook surface layer 49.

[0057] Working principle of this embodiment three: During the sliding process of the slide rod 34 inside the second straight guide groove 31, it slides and compresses the corresponding piston rod 40, thereby driving the piston block 39 to slide along the inner wall of the piston cylinder 35. The connecting spring 41 is stretched, thereby sending the air inside the piston cylinder 35 into the sealing plate 15 through the exhaust branch pipe 43, the hose, and the air supply pipe 50 in sequence. The air pressure inside the sealing plate 15 increases, causing the elastic diaphragm 44 to inflate and expand, blocking the sealing cavity 45, and improving the sealing performance of the connection between the upper flat suction part 4 and the lower flat suction part 5. When the slide rod 34 slides and compresses the inclined guide plate 36, causing the inclined guide plate 36 to slide along the corresponding Z-shaped plate 28 and be stored inside the corresponding Z-shaped plate 28, the corresponding return spring 38 is stretched. When the slide rod 34 disengages from the inclined guide plate 36, under the elastic return action of the return spring 38, the inclined guide plate 36 slides and returns to its original position to block the slide rod 34, thus completing the fixation and limitation of the semi-outer flat suction tube 25.

[0058] The rubber sleeve 8 is fitted onto the two halves of the outer flat suction tube 25 in the closed state, so that the rubber sealing ring 47 is engaged with the corresponding U-shaped groove 46. The rubber sleeve 8 is tied tightly to the two halves of the outer flat suction tube 25 in the closed state by the strap 48, thereby improving the sealing between the two halves of the outer flat suction tube 25 in the closed state. The setting of LED light 11 improves the cleaning ability of the flat suction structure in shadow corners (the movement process of the slide bar 34 is from the first straight guide groove 30 → oblique guide groove 32 → second straight guide groove 31).

[0059] When it is necessary to clean the inside of the two halves of the outer flat straw 25 in the closed state, remove the rubber sleeve 8 to release the restriction on the two halves of the outer flat straw 25, pull the inclined guide plate 36 upward to release the restriction on the corresponding slide rod 34, and the half outer flat straw 25 can slide towards the mounting shell 2, so that the corresponding slide rod 34 slides along the Z-shaped guide groove 29 (the above-mentioned movement process of the slide rod 34 is from the second straight guide groove 31 → inclined guide groove 32 → first straight guide groove 30).
