    BACKGROUND OF THE INVENTION
  • 1. Technical Field
  • The present invention relates to vacuum cleaners and, more particularly, to a dust-collecting auxiliary device that improves the dust-collecting efficiency of a vacuum cleaner.
  • 2. Description of Related Art
  • A typical vacuum cleaner primarily comprises a motor, a fan, a dust-collecting chamber and a suction inlet, wherein the motor drives the fan to create suction which passes through the dust-collecting chamber and sucks up external air, dust and trash at the suction inlet. As the collected air, dust and trash are drawn into the dust-collecting chamber, which possess reduced pressure due to the relatively large internal space, dust and trash which are relatively heavier than the air are retained in the chamber, while the air is successively filtered through a filter before exhausted from the cleaner at an exhaust.
  • Varied technical means for improving dust-collecting efficiency for various vacuum cleaners has been proposed. A traditional vacuum cleaner in an upright form with a detachable extension pipe, a suction tip and other components can perform relatively strong suction by implementing a relatively large and powerful motor. Alternatively, suction generated under equivalent motor power may by enhanced by simply replacing the suction tip with another having smaller suction inlet to enlarge vacuum pressure at the suction inlet.
  • The current trend is towards self-propelled vacuum cleaners having small volume, and equipped with remote controlling and automatic dust-collecting functions. Such a modern product, as disclosed in U.S. Design Pat. D524,495 and D503,251 generally has a disk-shaped boy and is welcome by the consumers for the advantages as light, easy to be stored, remote-controllable, adaptable, self-propelled and so on. However, the improvement in suction of such a disk-shaped vacuum cleaner may be limited by because the reduced volume thereof may not sufficient to accommodate a larger and powerful motor and the suction inlet thereof is not designed to be fixed an irreplaceable. Thus, a need exists for a disk-shaped vacuum cleaner that performs improved dust-collecting efficiency.
  • SUMMARY OF THE INVENTION

  • A dust-collecting auxiliary device is equipped on a vacuum cleaner that comprises at least a motor, a fan, a dust-collecting chamber, a suction inlet, wherein the motor drives the fan to create suction which passes through the dust-collecting chamber and sucks up external air, dust and trash at the suction inlet and draws the dust an trash into the dust-collecting chamber, and a driving device to propel the vacuum cleaner. Said dust-collecting auxiliary device includes at least one air pipe of which an air inlet at one end is fixed in a fan container of said fan and an air outlet at the opposite end is placed at the lower surface of the bottom cover of the vacuum cleaner adjacent to and with a distance from the suction inlet, at least two wings each with one end fixed at one side of the suction inlet, while the other end thereof extended forward and outward to give an increasing distance from another wing. The disclosed vacuum cleaner further comprises a dust wiper which is composed by battening a wiping cloth in a slot with a batten so that the vacuumed route can be successively cleaned by the wiping cloth.
  • Thus, the object of the present invention to provide a dust-collecting auxiliary device utilizing airflow blew form the air pipe to congregate dust or trash toward the suction inlet. Additionally, the two wings enlarge the dust-collecting area of the suction inlet suction inlet and facilitate converging airflow blew form the air pipe toward the suction inlet so that dust and trash in said dust-collecting area can be sucked through the suction inlet efficiently an smoothly due to the aid of the air pipe and wings.

  • FIG. 2 is a top view showing the inner composition of a vacuum cleaner according to the present invention;
  • FIG. 3 is an exploded view of the bottom portion of the disclosed vacuum cleaner;
  • FIG. 4 is a perspective view according to FIG. 3; and
  • FIG. 5 is a side view showing the inner composition of the disclosed vacuum cleaner.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • As a modern disk-shaped vacuum cleaner according to the present invention is schematically shown in the Figures, those details not related to the essentials of the present invention are not accounted herein. In the Figures, a motor 10, a fan 11, a dust-collecting chamber 12, a suction inlet 13 and a driving device 16 of prior art are disclosed, wherein the driving device 16 drives the vacuum cleaner moving automatically; the motor 10 rotates the fan 11 to generate suction which passes through the dust-collecting chamber 12 and sucks up external air, dust and trash at the suction inlet 13; and retains dust and trash in the dust-collecting chamber 12.
  • For improving dust-collecting ability of such a vacuum cleaner, the present invention provides a dust-collecting auxiliary device which is composed of two air pipes 20 and two wings 25 as shown in FIGS. 1 to 5.
  • Each of the air pipes 20 is a flexible tube, of which an inlet 21 at one end is fixed in a fan container 14 enclosed said fan 11, while an outlet 22 at the opposite end is fixed at the lower surface of the bottom cover 15 adjacent to and with a predetermined distance from one end of the suction inlet 13. For the outlet 22 of each air pipe 20, a nozzle 23 is provided at the lower surface of the bottom cover 15 inclined toward the suction inlet 13 and a nozzle hole 24 is attached to the end thereof. Also, the outlet 22 of each air pipe 20 is fixed in the corresponding nozzle 23.
  • The two wings 25 are made of flexible sheets and each wing 25 has one end respectively fixed at one side of the suction inlet 13, while the other ends thereof are extended forward and outward to give an increasing distance from another wing whereby a dust-collecting division 40, which is greater than the suction inlet 13 in width and accommodating said nozzles 23 is defined between the two wings 25. It is to be noted that the dust-collecting division 40 indicated in FIGS. 3 and 4 by dotted lines is just for illustrating the concept of the present invention, and is not for limiting the dust-collecting division 40 with an absolute spatial pattern.
  • In the disclosed vacuum cleaner, the motor 10 rotates the fan 11 to generate suction which passes through the dust-collecting chamber 12 and collects the external air, dust and trash at the suction inlet 13. As the collected dust and trash are retained in the dust-collecting chamber 12, the sucked air is then filtered by the filter of the dust-collecting chamber 12 before enters the two air pipes 20 through the fan container 14 to be further emitted by the nozzle holes 24 of nozzles 23. Since the nozzles 23 are inclined toward the suction inlet 13 and fenced by said wings 25, the emitted airflow can be oriented toward the suction inlet 13 and precisely facilitates collecting dust and trash and as a result enhances dust-collecting activity of the vacuum cleaner. Additionally, the dust-collecting division 40 defined by said two wings 25 enlarges dust-collecting area of the suction inlet 13 and beneficially aggrandizes dust-collecting ability of the vacuum cleaner.
  • Thus, the disclosed dust-collecting auxiliary device exactly enhances dust-collecting ability of the vacuum cleaner by implementing the two wings 25 to extend dust-collecting area around the suction inlet 13 and utilizing the exhausted air during dust-collecting to blow dust and trash in the dust-collecting area toward the suction inlet 13 for more smooth and fast dust-collecting.
  • In FIGS. 3 and 4, the dust-collecting auxiliary device of the present invention further comprises a dust wiper, which includes:
  • at least a slot 30 positioned at the lower surface of the bottom cover;
  • a first fastening portion 31 and a second fastening portion 32 provided respectively at the opposite ends of said slot 30; and
  • a batten 33 matching the slot 30 so that a wiping cloth 34 can be pressed into the slot 30 and the two ends of the batten 33 can be fastened by the first fastening portion 31 and a second fastening portion 32 thus an wiping cloth 34 can be fixed in the slot 30 and an edge thereof resultantly stretches out the slot 30.
  • Herein the fastening relationship between the batten 33 and the first fastening portion 31 and a second fastening portion 32 according to the particular embodiment is described. A fastening hole 311 and a gap 321 are relatively provided at the opposite ends of the slot 30, and a hook 323 is arranged on the bottom cover adjacent to the gap 321. Further, a salient 331 is provided on one end of the batten 33 and a retaining piece 332 is extended sidelong on the opposite end of the batten 33. Thus, when the batten 33 is pressed into the slot 30, the salient 331 can be fastened in the fastening hole 311 while the retaining piece 332 on other end can be retained by the hook 323 beyond the gap 321. By this means, the batten 33 and slot 30 can be mutually engaged in a detachable way and a wiping cloth 34 may be infixed into the slot 30 by the batten 33. According to the embodiment illustrated in the Figures, the wiping cloth 34 is replaceable.
  • As shown in FIG. 5, as wiping cloth 34 has its edge stretching out the slot 30 contacting the ground, it cleans the ground that the vacuum cleaner passes so that the cleaning efficiency can be improved by the dual cleaning of vacuuming and wiping.
  • Although a particular embodiment of the invention has been described in detail for purposes of illustration, it will be understood by one of ordinary skill in the art that numerous variations will be possible to the disclosed embodiments without going outside the scope of the invention as disclosed in the claims.
