Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner with an adjustable suction nozzle. Background Art

[0002] The suction nozzle is a common configuration component of vacuum cleaner products. The suction port of the suction nozzle has various shapes and sizes, which can lengthen the vacuum cleaner body and improve the surface cleaning ability.

[0003] In the vacuum cleaner products currently on the market, the size and dimensions of the suction port of the suction nozzle are fixed. However, in actual application environments, when facing different cleaning scenes or different materials to be cleaned, it is usually necessary to manually replace the appropriate suction nozzle to increase the suction size of the air port or adapt to the cleaning scene. For example, when cleaning a blanket, due to the rough surface of the blanket, the fluff has a higher adsorption force on impurities. At this time, it is necessary to replace the suction nozzle with a smaller suction port to increase the suction force and enhance the cleaning effect of the vacuum cleaner. However, there are many cleaning scenes in life. A single-sized suction port needs to be repeatedly cleaned manually due to insufficient suction or a small cleaning range, resulting in low cleaning efficiency and poor cleaning effect.

DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] The present invention provides a vacuum cleaner with an adjustable nozzle size, comprising a main body 1, a handle 2 is fixedly connected to the main body 1, a hose 3 is fixedly connected to one side of the main body 1, and a nozzle assembly 4 is installed at one end of the hose 3.

[0029] The suction nozzle assembly 4 includes a shell 41, and a pair of sealing plates 42 are symmetrically arranged inside the shell 41. The top and bottom of the pair of sealing plates 42 are fixedly connected to the top and bottom of the inner wall of the shell 41 respectively; a pair of movable plates 43 are symmetrically arranged between the pair of sealing plates 42; the side walls of the pair of movable plates 43 are symmetrically and vertically opened with first slide grooves 44; the pair of movable plates 43 are slidably connected to the pair of sealing plates 42 through the first slide grooves 44; through grooves 45 are horizontally opened on both sides of the shell 41; first sliders 46 are fixedly connected on both sides of the pair of movable plates 43; the first sliders 46 are slidably connected to the through grooves 45; second slide grooves 47 are vertically opened on one side of the pair of sealing plates 42; a pair of pleated seals 48 are fixedly connected between the pair of movable plates 43; one end of the pair of pleated seals 48 extends into the second slide groove 47 and is slidably connected to the second slide groove 47.

[0030] By moving a pair of movable plates 43 in relative directions to change the size of the suction port, the pleated seal 48 can be folded to adapt to the distance between the pair of movable plates 43, and one end of the pleated seal 48 extends into the second slide groove 47 to enhance the sealing ability of the connection between the pleated seal 48 and the sealing plate 42.

[0031] Among them, the top and bottom of the shell 41 are both provided with a accommodating cavity 49, and a moving block 411 is slidably connected in the accommodating cavity 49. A plurality of limiting rods 410 are horizontally penetrated on the moving block 411. The moving block 411 is slidably connected to the limiting rod 410, and both ends of the limiting rod 410 are sleeved with elastic parts 412, one end of the elastic part 412 is fixedly connected to the moving block 411, and the other end of the elastic part 412 is fixedly connected to the inner wall of the accommodating cavity 49.

[0032] Among them, an opening 413 is opened at the bottom of the accommodating cavity 49, and a sealing belt 414 is arranged in the opening 413. One end of the sealing belt 414 is fixedly connected to the side wall of the moving block 411, and the other end of the sealing belt 414 is fixedly connected to the side wall of the moving plate 43. The side wall of the sealing belt 414 is slidably connected to the side wall of the sealing plate 42.

[0033] It should be noted that the elastic member 412 is preferably a spring, the side wall of the opening 413 opened at the bottom of the accommodating cavity 49 is rounded and slidably connected to the sealing belt 414, and the material of the sealing belt 414 has a strong deformation ability.

[0034] Among them, a pair of first telescopic rods 415 are fixedly connected on both sides of the shell 41, and the output ends of the pair of first telescopic rods 415 are fixedly connected with Y-shaped push rods 416. A third sliding groove 417 is horizontally opened on the Y-shaped push rod 416, and a pin rod 418 is slidably connected in the third sliding groove 417. One end of the pin rod 418 is fixedly connected to the side wall of the first sliding block 46.

[0035] The Y-shaped push rod 416 is driven to move forward and backward by the first telescopic rod 415, so that the pin rod 418 slides in the third slide groove 417 of the Y-shaped push rod 416. Since the first slider 46 is fixedly connected to the pin rod 418, when the pin rod 418 slides in the third slide groove 417, it will drive the first slider 46 to slide in the through groove 45, thereby driving the movable plate 43 fixedly connected to one side of the first slider 46 to move, thereby realizing the adjustment of the distance between the movable plates 43, so as to achieve the purpose of changing the size of the suction port.

[0036] It should be noted that the pair of first telescopic rods 415 fixedly connected at both sides of the housing 41 are electrically connected to each other, so that the pair of first telescopic rods 415 operate synchronously.

[0037] Among them, four pairs of fourth sliding grooves 419 are horizontally opened on a pair of the movable plates 43, and the four pairs of the fourth sliding grooves 419 are respectively located on both sides of the pleated seals 48, and the inner walls of the four pairs of the fourth sliding grooves 419 are symmetrically and horizontally opened with limiting grooves 420, and the four pairs of the fourth sliding grooves 419 are slidably connected with second sliders 421, and limiting blocks 422 are symmetrically fixedly connected on both sides of the second sliders 421. The limiting blocks 422 are slidably connected to the limiting grooves 420, and a rotating rod 423 is fixedly connected to the top of the second slider 421, and a pair of support rods 424 are symmetrically arranged on both sides of the pair of pleated seals 48. The pair of support rods 424 are cross-connected and rotatably connected by axle pins, and both ends of the support rods 424 are rotatably connected to the rotating rod 423.

[0038] The movable plate 43 is supported by multiple pairs of crossed support rods 424 to improve the stability of the movement of the movable plate 43. When a pair of movable plates 43 are displaced in relative directions or opposite directions, the second slider 421 rotatably connected to the two ends of the support rod 424 by the rotating rod 423 will move along the fourth slide groove 419, thereby changing the angle between the support rod 424 and the movable plate 43, thereby adapting to the different distances between the pair of movable plates 43. At the same time, the support rods 424 located on both sides of the pleated seal 48 have a certain protective effect on the pleated seal 48.

[0039] The nozzle assembly 4 further comprises a bundle tube 425 fixedly connected to the side wall of the shell 41 , the bundle tube 425 is communicated with the inside of the shell 41 , the bundle tube 425 is threadedly connected to one end of the hose 3 , and an adjustment mechanism 5 is fixedly connected to the bundle tube 425 .

[0040] Among them, the adjustment mechanism 5 includes a pair of connecting members 51 fixedly connected to both sides of the bundle tube 425, and a rotating shaft 52 is fixedly connected to the pair of connecting members 51. One end of the rotating shaft 52 is fixedly connected to a steering block 53, and a guide groove 54 is horizontally opened on the steering block 53. The pair of connecting members 51 are rotatably connected to a pair of connecting rods 55 through the rotating shaft 52. One end of the pair of connecting rods 55 is fixedly connected to both sides of the handle 2, and one side of the handle 2 is fixedly connected to a second telescopic rod 56. The output end of the second telescopic rod 56 is fixedly connected to a U-shaped frame 57, and the inner wall of the U-shaped frame 57 is symmetrically fixedly connected to a guide rod 58, and the guide rod 58 is slidably connected to the guide groove 54.

[0041] Embodiment 1: Figure 1-7As shown, in this embodiment, during the use of the vacuum cleaner, the first telescopic rod 415 is started to drive the Y-shaped push rod 416 to move, so that the pin rod 418 slidably connected in the third slide groove 417 is displaced along the third slide groove 417, thereby driving the first sliding block 46 fixedly connected to one end of the pin rod 418 to move in the through groove 45 horizontally opened on the side wall of the shell 41, and then driving the pair of movable plates 43 to move in relative or opposite directions, changing the suction port width of the suction nozzle assembly 4, and the pair of pleated seals 48 fixedly connected between the pair of movable plates 43 will adapt to the distance between the pair of movable plates 43 to shrink or extend, thereby cooperating with the sealing plate 42 to seal the two sides of the pair of movable plates 43, and when the pair of movable plates 43 are displaced in relative directions, the movable plates 43 drag the sealing belt 414 fixedly connected to the movable plates 43 from the bottom opening 413 of the accommodating chamber 49. The movable block 411 extending out and located inside the accommodating chamber 49 moves toward the opening 413 along the limiting rod 410 under the drag of the sealing belt 414. At this time, the elastic member 412 located on one side of the movable block 411 (opening 413) is compressed, while the elastic member 412 located on the other side of the movable block 411 is extended. When a pair of movable plates 43 move in opposite directions, the compressed elastic member 412 gradually rebounds, and the extended elastic member 412 gradually shrinks, thereby driving the movable block 411 to drag the sealing belt 414 into the accommodating chamber 49, and the sealing belt 414 fits with the side wall of the sealing plate 42, so that when the size of the suction port is adjusted, the interior is always in a sealed state, thereby improving the suction effect of the suction port, increasing the suction force of the suction port by adjusting the size or adjusting the cleaning range of the suction port, thereby improving the cleaning efficiency and cleaning effect.

[0042] It should be noted that: when the size of the suction port of the suction nozzle assembly 4 is gradually reduced, the suction force of the suction port is increased and the cleaning range is reduced. Conversely, the suction force of the suction port is reduced and the cleaning range is increased.

[0043] By starting the second telescopic rod 56 to drive the U-shaped frame 57 to move, the guide rod 58 symmetrically fixedly connected to the inner wall of the U-shaped frame 57 moves in the guide groove 54 horizontally opened on the steering block 53. Since the steering block 53 is fixedly connected to the connecting member 51 through the rotating shaft 52, and the rotating shaft 52 is rotatably connected to the connecting rod 55, when the guide rod 58 drives the steering block 53 to rotate around the rotating shaft 52 by sliding in the guide groove 54, the connecting member 51 rotates synchronously. Since the connecting member 51 is fixedly connected to the bundle tube 425, the suction nozzle assembly 4 is driven to rotate, and then the suction angle between the suction port of the suction nozzle assembly 4 and the cleaning position is adjusted to be the most suitable, thereby improving the cleaning effect. The user does not need to manually adjust the suction angle between the suction port and the cleaning position by adjusting the holding posture of the device, and the use is more convenient and easy.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
