Background

People who often use pencils have common trouble, namely rubber scraps generated by using the rubber are inconvenient to clean, and the problem can be well solved by using the rubber scraps cleaner, so that the pencil is a table top cleaning tool. Meanwhile, in the process of using the rubber crumb cleaner, problems exist, such as that rubber crumb is easy to adhere to the inside of the crumb storage bin and the fan blade, the resistance of the cleaner motor is not easy to clean and is increased, the service life of the cleaner motor is shortened, and the novel rubber crumb cleaner is required to be designed, so that the purposes of enabling the rubber crumb cleaner to be more convenient to use and more durable are achieved.

Disclosure of Invention

In order to solve the problems that the traditional rubber crumb cleaner is inconvenient to clean and collect the crumb garbage, blocks a fan and the like, the utility model provides a handheld desktop crumb cleaner, which is integrally cylindrical and is formed by connecting cylindrical coaxial components with different diameters from top to bottom, wherein the uppermost part is a thinner cylindrical handle, a cleaner power switch is arranged, a battery is arranged in the handle, or the handheld desktop crumb cleaner is directly plugged in for use, and when a rechargeable battery is arranged, the handheld desktop crumb cleaner can be used in a rechargeable manner. An air outlet is arranged at the upper end of the handle, so that the air exhaust is convenient. The handle is connected with the thickened cylindrical shell, a round table type reducing cylinder used for transitional connection is arranged between the handle and the shell, a small negative pressure fan is arranged in the reducing cylinder, when the small negative pressure fan rotates at a high speed, air in a lower Fang Fuya bin of the small negative pressure fan is rapidly discharged, negative pressure is generated, and external light-weight debris can be sucked into the negative pressure bin to be cleaned. In order to facilitate the debris discharge treatment in the suction negative pressure bin, a debris collecting net cover is arranged in the negative pressure bin and is tightly clung to the side wall of the negative pressure bin and the bottom surface below the negative pressure bin, the negative pressure bin is tightly sleeved on a tail pipe of the horn-shaped air inlet, the connecting interface is sealed, and air leakage is prevented when the debris is adsorbed. The cylindrical shell bottom is connected with a horn-shaped air inlet, which is called a horn mouth, the cleaning area is increased downwards, a brush is adhered to the periphery of the horn mouth, and when the scraps are cleaned, the scraps adhered to the tabletop are scraped loose and sucked into the negative pressure bin conveniently.

The utility model can be further optimized, the chip collecting net cover is a cylindrical porous material net cover with a closed top, can be made of metal or plastic, is provided with uniform round holes or equilateral holes, can be a flexible net bag, and has the main effects of wrapping up the chip garbage sucked into the negative pressure bin for integral cleaning, so that the ideal chip collecting effect is achieved, the size of the holes in the net cover is moderate, the number of the holes is as large as possible, the air flow is convenient to form a good negative pressure effect, but the interception effect of the chips caused by the overlarge holes is poor, a large amount of chips can flow out of the cleaner to pollute the air, the holes are too small and bad, and larger resistance is generated to the sucked air, so that the negative pressure effect is poor, and the suction effect of the chips is influenced. Through repeated experiments, the ideal data are measured as follows: the diameter of the circular hole of the net cover is 0.5-2 MM, or the diameter of the equilateral Kong Bianchang is 0.5-2 MM, wherein the best data is that the diameter of the circular hole is 1MM, or the diameter of the equilateral Kong Bianchang is 1MM.

In order to conveniently clean the debris garbage in the negative pressure bin, the debris collecting net cover and the air inlet are of an integral disassembly and assembly structure, the three parts can be integrally taken out from the shell of the debris cleaner, can be quickly washed down under a faucet, can be installed and recycled after being dried in the sun or in the air, can also be immediately installed and recycled after being washed down, and can be used after being dried by a small negative pressure fan. If the chips are stuck on the parts and cannot be washed cleanly, the three parts can be disassembled one by one and washed again, or the three parts can be brushed by a brush.

The connection mode between the detachable parts is one of a magnetic attraction type, a buckling type and a threaded type, so that the detachable parts are convenient to assemble and disassemble on one hand, the stability after being installed is improved on the other hand, and the loosening of the parts is prevented.

In order to further improve the effect of collecting the scraps and garbage, the surface of the net cover is provided with an electrostatic adsorption material, so that tiny dust particles sucked into the negative pressure bin can be adsorbed to the net cover, and dust flying caused during scraps cleaning is avoided.

Detailed Description

The utility model is further illustrated by the following examples, which are given solely for the purpose of illustration and are not to be construed as limitations of the present utility model.

[ example ]

A handheld dust collection cleaner for cleaning scraps, such as rubber scraps, crushed paper scraps and the like on a desk top is designed and manufactured, and the cleaner is modified on the basis of the traditional handheld desktop cleaner. Fig. 1 is a longitudinal sectional view of a hand-held tabletop debris cleaner, wherein the overall debris cleaner is cylindrical, and is formed by connecting cylindrical coaxial components with different diameters from top to bottom, the uppermost surface is a thinner cylindrical handle 1, a cleaner power switch is arranged, two 18650 batteries are arranged in the handle, or the hand-held tabletop debris cleaner is directly plugged in for use, and when a rechargeable battery is arranged, the hand-held tabletop debris cleaner can be used for recharging. An air outlet is arranged at the upper end of the handle, so that the air exhaust is convenient. The handle 1 is connected with a thickened cylindrical shell 6, a round table type diameter-changing cylinder 3 for transitional connection is arranged between the handle 1 and the shell, a negative pressure small fan 2 is arranged in the diameter-changing cylinder 3, the negative pressure small fan 2 can rotate at a high speed of 25000 revolutions per minute, a strong suction force of 5000Pa can be generated, air in a lower Fang Fuya bin 4 is rapidly discharged, negative pressure is generated, and external light debris can be sucked into the negative pressure bin 4 to finish cleaning.
