Description

Automatic paper feeder for toilet paper

The utility model relates to an automatic adsorption paper feeding device of toilet paper.

In the prior art, as shown in the disclosure of Taiwan application No. 80203071 entitled "electric toilet paper roll capable of setting sheet number", it is known from the scope and illustration of the patent, which mainly comprises a base, a roll cover, and a control circuit; wherein, a driving device which drives a plurality of gears by a motor, a battery box, a starting switch and a plurality of selection switches are formed in the base; a reel cover, the front end of which forms a horizontal strip tip, and the middle of the horizontal strip tip forms a hollow round groove which can contain the upper rubber roller; therefore, when the starting switch is pressed, the motor of the driving device is started through the control circuit, the lower rubber roller is driven through the gear set, the toilet paper is sent out, and when the length required by the sheet number selection switch is reached, the motor is closed; so as to achieve the purposes of automatic paper feeding and convenient use. In the light of the above, however,

according to the above elements, the device drives the motor to drive the gear to rotate by using the battery and the control circuit, which not only wastes electric power, but also has high failure rate and short service life; especially, the electric power-free electric heater cannot be used at all when no electric power is available, and is a use product which has high manufacturing and use cost and is not in line with economic benefit.

In addition, there is a patent publication of Taiwan application No. 82210675, namely the structure of automatic toilet paper and notepaper for stationery case, which is disclosed in the patent scope and drawings, the device is mainly characterized in that an external pen is inserted and rotated to screw a scroll spring, the scroll spring is coaxially connected with a large gear, the large gear is engaged with a small gear, when the scroll spring is screwed, the small gear jumps out of engagement through an elliptical hole, when the scroll spring releases elastic force, the large gear is rotated to engage with the small gear again, and the large gear formed integrally with the small gear can be engaged with a gear on a conveying wheel arranged in the center of three conveying wheels to rotate clockwise and cooperate with the conveying wheels to convey toilet paper; when the note paper is to be conveyed, the push buttons beside the two convex bamboo shoots are pushed inwards, the movable wheel is driven upwards to be separated from the conveying wheel by the switching set device, and the gear on the movable wheel is separated from the large gear and is meshed with the idle wheel, so that when the elasticity of the scroll spring is released, the movable wheel can be driven to rotate reversely to be matched with the conveying wheel to send out the note paper. Although, this creation can achieve the effect of transporting paper by using basic mechanical principle without the above-mentioned assistance of electric power and electronic components; in the light of the above, however,

although the device can have the using function of a writing case, the probability of using the toilet paper on an office desk is quite low, the device is practical without multiple functions, but the device has the fear of adding enough pictures, and when the toilet paper and the note paper are used, the convex bamboo shoots are required to be pressed, the type of conveying is changed by using the switching device, the inconvenience in operation and use is increased virtually, and the problem of confusion in use is easily caused.

Furthermore, when the device is used, the volute flat spring has moderate rebound force, so that a certain force is needed to pull, and in order to save more labor and be light in operation, a pen is inserted and fixed on the sleeve body 81 to lengthen the force arm; therefore, not only the inconvenience that other elements are needed in operation is increased, but also the pen is only nested at the tail end, and when the upper end of the pen is held and pulled downwards without pivot or fixation, the pen is easy to be separated from the sleeve body 81, and the pen shape is the same as the nominal one below the pen is held, (the arm of force is short) in operation, so that the pen is difficult to control in holding and positioning, and the operation is unsmooth.

In addition, the device has multiple using functions and needs to be operated by matching with a pen, for example, when toilet paper, hand towel or kitchen paper towel used in a common public toilet is used, the device cannot be applied at all (can one go to the toilet and carry the pen), so the device only has the using effect of an office table, and the application range is narrow.

Therefore, the main objective of the present invention is to provide an automatic toilet paper feeding device, which can thoroughly eliminate the existing defects of the existing products, and can achieve the effect of automatically feeding paper only by using the basic mechanical principle without using electric power and electronic components, and can be operated without using other components, so that the user can obtain more convenient and labor-saving operation effect, and the application range can be improved, so that the device can be applied to rolled toilet paper, paper wiping towel or kitchen paper towel.
