Description
- The present invention relates to a hand-held vacuum lint remover for removing lint, dust, and foreign materials from the clothing or fabric objects to clean them.
- A vacuum lint remover is a device known for severing and removing lint or foreign materials from the clothing. Examples include a lint removing device having an externally-powered electric motor employed or connected in the device, in which the electric motor rotates brushes and the vacuum generating fan as well to remove lint and dust from the object clothing while brushing the same to facilitate the removing of lint. However, such conventional lint removing devices are generally bulky and have a limited portability in use since an electric cord needs to be attached to the device. Moreover, the lint remover with such rotating brushes incorporate many machine elements such as gear trains and rotary shafts to make the brushes in appropriate speed, and thus, the manufacturing cost for the device becomes relatively high.
- For another example, another type of lint removers is known, which incorporates rotating scrapers (or cutting blades) positioned inside a stationary cover having holes on its surface for receiving the pilled materials there-through in order to sever the pilled materials by the rotating scrapers. In this device, the interior surface of the stationary cover functions as a stationary scraper to cut the lint or pilled materials in cooperation with the inwardly positioned rotating scrapers, in a manner generally similar to the conventional mechanism of electric savers. Accordingly, with this structure the pilled materials (e.., residual or matted fibers, wools, other fabrics, dust, etc.) can be stuck inside or tangled over the narrow space between the rotating scrapers and the stationary cover, and thus, hindering the severing operation of the rotating scrapers. Moreover, this type of lint removing device requires a higher machining accuracy in producing the rotating scrapers and corresponding stationary covers, thus, requiring a higher manufacturing cost.
- Moreover, conventional lint removers typically include a complex structure for storing the lint in the device, attaching and detaching the lint container to and from the lint remover after dumping or removing the stored lint from the container.
- In order to solve the above described and other shortcomings or drawbacks known in the conventional vacuum lint removers, the present invention provides a vacuum lint remover with a compact and portable design to be conveniently held with a hand and also for easy operation by the user. The lint remover of the invention also provides an effective design for the dust container which is detachably attached onto the hand grip portion of the device, in which the grip portion is adapted to receive a rechargeable battery, thus, making the device more compact, while also enabling an easy operation of the device in use. Moreover, with the detachable dust container structure, the dust container of the lint remover is easily attached to and detached from the handle portion of the device to remove the stored dust from the container. Moreover, with the resilient dust escape prevention member (one-way valve), the lint remover of the invention can also be used without fearing the risks of the leakage or escape of the stored dust through the inlet opening.
- According to one preferred embodiment of the present invention, a vacuum lint remover comprises: a housing including a head portion with an inlet opening for taking air there-through, and a handle portion extending generally laterally from the head portion and configured to be held with a hand; an impeller received in the head portion of the housing to provide an air flow upon rotation; an actuator (e.g., an electric motor) disposed adjacent to the impeller and adapted to rotate the impeller; a battery compartment in the handle portion of the housing, the battery compartment configured to receive a battery therein to operate the actuator; and a dust container detachably attached to a bottom portion of the handle portion of the housing, the dust container having a front opening for receiving the air flow from the impeller, and at least one window to discharge the air there-from, the dust container having a filtering or screening member disposed at the window to filter dust and foreign materials while allowing the air discharge from the window.
- According to one preferred embodiment, the impeller is preferably of a radial flow type, and the actuator is placed above the impeller and has a rotation shaft coupled to the impeller. The head portion preferably has a vertically extending narrow tip portion, and the inlet opening can be provided at the narrow tip portion, with a brush is disposed at the font side of the inlet opening to facilitate removing of the foreign materials and dust from the object clothing.
- According to another preferred embodiment, the vacuum lint remover further includes a dust escape prevention member, preferably made of elastic rubber or other resilient and elastic materials, which is disposed at the front opening of the dust container and configured to prevent a reversal flow of the dust and foreign materials from the dust container. The dust escape prevention member can include one or more cuts formed therein such that a re-closable opening can be formed in the dust escape prevention member due to the cuts when the pressure of the air flow from the impeller reaches at a predetermined level, wherein the opening is to be re-closed when the impeller is stopped.
- The handle portion of the housing preferably includes an on-off switch electrically connected to the battery to turn on or off the operation of the actuator, the on-off switch positioned at a front side of the handle portion to facilitate the on-off operation with a thumb of the user as the user operates the vacuum lint remover while holding the handle portion of the housing with a hand. In addition, the handle portion of the housing can include a foldable plug, preferably at a rear portion of the handle portion, wherein the foldable plug is configured to connect an electric source when unfolded, in order to recharge the battery.

Thehousing 110 consists generally of a front orhead portion 110 a and a rear or handle portion 110 b, with the handle portion 110 b extending generally laterally from thehead portion 110 a as shown. Thehead portion 110 a includesimpeller housing 112 for receiving animpeller 130 therein, andmotor housing 114 for receiving an actuator (e.g., electric motor 140) therein. Theimpeller housing 112 preferably has a generally beak or bill-like shape with a narrow downward protrusion ortip portion 116 defining aninlet opening 118 which is shaped to facilitate the introduction of the external air and foreign materials (such as lint, residual fabrics, fibers, and dust) from the clothing to clean it. The inlet opening 118 is generally shaped to have a narrow but relatively wide opening, for example, a wide rectangular opening as shown inFIG. 2 . Theimpeller housing 112 further defines therein anair passage channel 120 having a generally conical shape as shown inFIG. 1 . However, thetip portion 116, theinlet 118, and theair passage channel 120 can have other shapes known in the art, other than the shapes as shown in the drawings, as long as they can facilitate the introduction of the air and lint mixture from the object clothing. - In order to facilitate the removal of lint, dust, and other foreign objects from the clothing, a
brush 124, preferably formed with a plurality of bristles of suitable length, is provided in thetip portion 116. As in the present embodiment as shown, thebrush 124 is preferably provided on a front ordistal side 117 of thetip portion 116. Thus, the lint and dust on the clothing is easily gathered toward theinlet area 118 when the user pulls and scrub the device 100 (while holding the device in the orientation as shown inFIG. 1 ) along the clothing placed below and toward the user. Accordingly, with thebrush 124, it can facilitate the intake of the removed foreign materials through the inlet opening 118. -
Impeller 130 is rotatably connected to a rotatingshaft 142 ofmotor 140 which is positioned inside thehousing 114 and electrically connected to one or more batteries (not shown) placed inside abattery compartment 150. Theimpeller 130 is a radial flow type configured to blow the air (with dust) “A” from the front axial side of the impeller toward the lateral or radial side of the impeller as illustrated inFIG. 1 . The battery to be received in thebattery compartment 150 is preferably of rechargeable type having a suitable power to rotate themotor 140. However, non-rechargeable type batteries can alternatively be used. When using the rechargeable type batteries, the rear end portion of thebattery compartment 150 is adapted to connect to an electric source. For example, as shown inFIG. 1 , an electric plug, preferably offoldable type plug 160, is provided at the rear end of thebattery compartment 150 to plug into an electric source after unfolding it in order to charge the rechargeable battery. An on-off switch 155 is provided at a front side end portion of thebattery compartment 150 at a suitable location to reach with a thumb of the user as the user hold the handle portion (i.e., thebattery compartment 150 and thedust container 170 to be described below) with a hand to operate themotor 140 with theswitch 155. -
Dust container 170 is provided at a bottom portion of thebattery compartment 150 for storing lint, dust, and other foreign materials removed from the clothing by operation of theimpeller 130. Thedust container 170 and thebattery compartment 150 together have a generally rectangular box shape (working as a handle) with suitable size to be held with a hand. The left side end of thedust container 170 is open to enable the introduction of the air “A” from theimpeller 130 and to store the dust in thedust container 170. The air “A” flows within thedust container 170 and exits through holes orwindows 172 provided at the wall of thedust container 170. As shown inFIGS. 1 and 2 , thewindows 172 are preferably provided at the rear side portion and the rear end portion of thedust container 170 to facilitate the air flow. Air filters orscreen members 180 are attached to the inner side of thewindows 172 in order to allow the air “A” to exit from thewindows 172, while preventing the dust and lint from escaping from thewindows 172. With this structure, lint and dust can effectively be stored and accumulated within thedust container 170. The upper side of the generally rectangularshaped dust container 170 is preferably open (as shown inFIG. 3 ) in order to facilitate discharging or dumping of the stored lint and dust from thedust container 170 after using the device. However, in another embodiment, the upper side of thedust container 170 can be closed with a thin wall portion. In this alternative embodiment, the discharging of the stored lint and dust can be accomplished through the opening at the left side end of thedust container 170. - The
dust container 170 is detachably attached to the bottom portion of thebattery compartment 150 as illustrated inFIG. 3 . For realizing the detachable attachment, the bottom wall of the battery compartment, or its equivalent structural wall member of thehousing 110, includes at least a pair ofprotrusions 176, and thedust container 170 has corresponding pairs ofengagements 178 for releasably catching theprotrusions 176.

In another embodiment as shown inFIG. 5 , the dustescape prevention member 190 a includes diagonal orslanted cuts 197, and thus, defining a cross (“X”) or star-like shape with the cuts. With this structure, the dustescape prevention member 190 a can provide a four-pointed star-like opening (not shown) at the center when the air flow from theimpeller 130 exceeds a predetermined air pressure to push open the fourflap portions 198, which opening will be reclosed by the returning force of theelastic member 190 a when theimpeller 130 is turned off. In this manner, the dustescape prevention members dust container 170, and also as a one-way valve to provide a selective communicating channel or opening to the inlet side of theduct container 170 to transport the lint and dust into the dust container for retaining therein without an accidental discharge to the environment. As shown inFIGS. 4 and 5 , the narrow cuts preferably include round through-holes 199 (having a hole diameter slightly larger than the width of the cuts) at the starting points of the cuts adjacent to the four corners of the dustescape prevention members elastic members - It is also noted that the dust
escape prevention member 190 can have various different shapes other than illustrated and described above as long as they can have the above-stated one-way valve and dust reverse-flow preventing functions. For example, the cuts in the dustescape prevention member 190 can have other shapes than the above-illustrated “H” shape or cross (“X”-like) shapes, for instance, a “U”-like shape (not shown) with one flap reclosably openable in operation. - Accordingly, as described above, the vacuum lint remover of the present invention is provided with a compact structure and portable design to be conveniently held with a hand and also for easy operation by the user. The lint remover of the invention also provides an effective design for the dust container which is detachably attached onto the handle portion of the device, in which the handle portion is adapted to receive a rechargeable battery therein, thus, making the device more compact, while also enabling an easy handling of the device in use. Moreover, with the detachable dust container structure, the dust container of the lint remover is easily attached to and detached from the handle portion of the device to remove the stored dust from the container. Moreover, with the resilient one-way valve (dust escape prevention member), the lint remover of the invention can also be used without fearing the risk of the leakage or escape of the stored dust through the inlet opening.
- The above disclosed embodiments of the invention are representatives of a presently preferred form of the invention, and are intended to be illustrative rather than definitive thereof. Accordingly, those skilled in the art will appreciate or recognize that various modifications and substitutions can be made thereto without departing from the spirit and scope of the present invention as set forth in the appended claims.
