The present invention relates to a cleaning pen, more particularly to a cleaning pen including a hollow clamping device and a wiping element, wherein the hollow clamping device consists of two clamping units which can be engaged with each other to form a single piece for clamping the wiping element in a bent state and allowing a bent portion of the wiping element to jut out of the cleaning pen and be used for cleaning an object, so as to effectively prevent the object from being scratched by edge of the wiping element and prolong service life of the wiping element.
Nowadays, cell phones, digital cameras, and like digital products are generally equipped with display screens and lenses. However, as the display screens and the lenses are exposed on the outside of such digital products, they are likely to be soiled by airborne dust, which prevents users from viewing or capturing clear images with these digital products.
Conventionally, a wiping cloth is used to wipe off the grease, dust, etc. on the display screens or the lenses, and yet the cleaning effect of the wiping cloth is limited by the shape of the users' fingers, for it is impossible to insert a human finger into the small corners or recessed edges of the display screens and the lenses. As a result, the cleaning tends to be incomplete, and the grime remaining on the display screens and the lenses not only continues to compromise the quality of the images displayed or captured, but also keeps accumulating and hardening. When the display screens and the lenses are subsequently wiped again, the hardened grime may abrade their surfaces and leave permanent scratches thereon.
As a solution to the aforesaid problem, a cleaning pen has been developed, as shown in
Nevertheless, market surveys have shown that the cleaning pen 1 has the following two major drawbacks in use:
1. Due to the properties of the materials, the wiping cloth 12 with the carbon coating is not suitable for cleaning display screens. Therefore, a user wishing to clean a display screen with the cleaning pen 1 has to buy another cleaning pen designed specifically for cleaning display screens, which is inconvenient.
2. As the wiping cloth 12 of the cleaning pen 1 wipes off the grime on a lens, the grime adheres to the wiping cloth 12. Moreover, the grime accumulated on the wiping cloth 12 increases with the number of use of the wiping cloth 12. Since the wiping cloth 12 of the cleaning pen 1 cannot be replaced directly, the user has no choice but to buy a new cleaning pen 1 when a certain amount of grime has accumulated on the wiping cloth 12, thereby preventing the grime on the wiping cloth 12 from falling on, attaching to, or even scratching the lens.
Now that the service life of the cleaning pen 1 cannot be effectively extended, new cleaning pens 1 must be bought on a regular basis. Besides, the risk of scratching is always present when using the cleaning pen 1 to clean a lens. Furthermore, as stated above, the carbon coated wiping cloth 12 is not suitable for cleaning display screens. In short, the cleaning pen 1 is still inconvenient to use and may cause trouble to its users.
Therefore, the present invention is intended to overcome the drawbacks of the foregoing cleaning pen while providing means of effectively cleaning display screens as well as lenses.
In view of the above, the inventor of the present invention has developed a novel cleaning pen as disclosed herein whose service life, unlike that of the conventional cleaning pen, is effectively extended, whose cleaning effect on an object to be cleaned (e.g., a display screen, a lens, etc.) is enhanced, and which is prevented from scratching the object being cleaned.
It is an object of the present invention to provide a cleaning pen which includes a hollow clamping device, a wiping element, and a hollow housing. The hollow clamping device consists, of two clamping units which can be engaged with each other to form a single piece for clamping the wiping element in a bent state and allowing a bent portion of the wiping element to jut out of the hollow clamping device. The hollow clamping device can be inserted into and fixed in position in the hollow housing such that the bent portion of the wiping element juts out of the hollow housing. The bent portion of the wiping element is wetted by a cleaning liquid and then used to clean an object. When the wiping element is soiled or damaged, it can be conveniently and sequentially taken out from the hollow housing and the hollow clamping device and be bent again, thereby shifting the soiled or damaged portion of the wiping element to a position where it is clamped by the hollow clamping device and allowing a clean portion of the wiping element to jut out of the hollow clamping device. After the cleaning pen is reassembled, a clean bent portion of the wiping element can be used for cleaning. Thus, not only is a thorough cleaning effect achievable, but also the grime attached to the wiping element is prevented from scratching the object being cleaned. Moreover, the service life of the wiping element is effectively increased.
It is another object of the present invention to provide the foregoing cleaning pen, wherein the other end of the hollow housing is provided with a receiving cavity for containing the cleaning liquid, and the cleaning pen further includes a nozzle head covering and fixed in position to the receiving cavity. A user wishing to clean an object with the cleaning pen can direct the nozzle of the nozzle head toward the object and press the nozzle head such that the nozzle head draws the cleaning liquid in the receiving cavity and sprays the cleaning liquid on the object. Then, the user can wet the wiping element conveniently with the cleaning liquid on the object and clean the object thoroughly.
It is yet another object of the present invention to provide the foregoing cleaning pen, wherein the hollow housing is provided with a cleaning brush at the end opposite the hollow clamping device. Thus, a user can brush dust or dirt particles off the surface of an object to be cleaned before cleaning the object with the wiping element, for if the object is directly wiped, with the dust or dirt particles still attached thereto, the object is very likely to be scratched by the wiping action.
It is a further object of the present invention to provide the foregoing cleaning pen, wherein a retracting seat is movably provided in the hollow housing and has an end provided with a cleaning brush. By moving the retracting seat, the cleaning brush is extended out of the hollow housing or is received therein.
The invention as well as a preferred mode of use, further objects, and advantages thereof will be best understood by referring to the following detailed description of some illustrative embodiments in conjunction with the accompanying drawings, in which:
The present invention relates to a cleaning pen. A preferred embodiment of the present invention is shown in
A user can wet the bent portion 203 of the wiping element 20 with a cleaning liquid such that the cleaning liquid penetrates the wiping layer 202 evenly and is absorbed by the absorbent material 201. The user can then hold the hollow housing 22 and use the soft and fine surface of the bent portion 203 of the wiping element 20 to clean an object (e.g., a display screen, a lens, etc.). Once the wiping layer 202 of the wiping element 20 is soiled or damaged, the hollow clamping device 21 can be easily removed from the first end of the hollow housing 22, and the clamping units 210 disengaged from each other, so as to take out the wiping element 20 for adjustment. For instance, the bent portion 203 of the wiping element 20 is adjusted by bending the wiping element 20 again such that the soiled or damaged portion of the wiping layer 202 is moved to a position to be fixedly clamped by the clamping units 210 while a clean portion of the wiping layer 202 protrudes from the hollow clamping device 21. After the wiping element 20, the hollow clamping device 21, and the hollow housing 22 are sequentially put together, the now clean bent portion 203 of the wiping element 20 is ready to be used for cleaning. Thus, a thorough cleaning effect is ensured, the object to be cleaned is prevented from being scratched by the grime on the wiping layer 202, and the service life of the wiping element 20 is also effectively extended.
