Abstract
The utility model relates to the field of office stationery, in particular to a cleaning pencil. A lead refill is arranged in a pencil holder. A cleaning unit is arranged at one end of the pencil holder, and comprises a tubular sleeve. A piston is arranged in the tubular sleeve, and forms sliding and sealing fit with the inner wall of the sleeve. One end of the pencil holder extends into the sleeve from an open hole in the bottom of one end of the sleeve, and is connected with the piston. An end cover is arranged at the other end of the sleeve. A liquid outlet communicated with an inner cavity of the sleeve is formed in the end cover. According to the cleaning pencil, a cleaning agent is stored in the inner cavity of the sleeve, and when a hand of a user is contaminated by stains, the pencil holder is squeezed to drive the piston to slide in the sleeve to discharge a certain amount of cleaning agent through the liquid outlet to clean the stains on the hand; the cleaning pencil is simple in structure and easy to implement; in addition, the cleaning unit is arranged on the pencil holder, so that the probability of the pencil is improved, and the pencil is convenient to use.
Description
Technical field
The utility model relates to office stationary field, particularly a kind of clean pencil.
Background technology
In prior art, pencil is widely used in the middle of people's learning life as a kind of conventional writing implement.And the student of kindergarten or primary school is in using the process of pencil, often because of carelessness pencil to be drawn and made to stay on hand spot on hand or because the mode of writing is incorrect, these spot waters are difficult to clean up.These spots are easy to be wiped the clothes of making dirty on clothes, are also easy to cause hygienic issues when child has a meal or eats a piece.
Utility model content
The purpose of this utility model is to provide a kind of clean pencil, can effectively to the spot of staying in writing process on hand, clean.
For realizing above object, the technical solution adopted in the utility model is: a kind of clean pencil, pen core is set in penholder, one end of described penholder is provided with cleaning unit, described cleaning unit comprises the sleeve of tubulose, piston is set in sleeve, between described piston and sleeve lining, forms slippage and be sealed and matched; One end of penholder is extended and is connected with piston in sleeve from the tapping of cylinder bottom, sleeve one end, and the other end of sleeve arranges end cap, and the liquid outlet that is communicated with barrel bore is set on described end cap.
Compared with prior art, there is following technique effect in the utility model:
In barrel bore, store cleaning agent, when user has spot to produce on hand, by extruding penholder, drive piston to slide in sleeve, make liquid outlet emit a certain amount of cleaning agent and clean spot on hand, this is simple in structure, easily realizes; , cleaning unit is arranged on penholder meanwhile, improves its portability, it is extremely convenient to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with Fig. 1, the utility model is described in further detail:
Consult Fig. 1, a kind of clean pencil, the interior pen core 20 that arranges of penholder 10, one end of described penholder 10 is provided with cleaning unit 30, described cleaning unit 30 comprises the sleeve 31 of tubulose, the interior piston 32 that arranges of sleeve 31, forms slippage between described piston 32 and sleeve 31 inwalls and is sealed and matched, and piston 32 is similar to syringe with the operating principle of sleeve 31 herein; One end of penholder 10 is connected to the interior extension of sleeve 31 and with piston 32 from perforate 311 places of sleeve 31 cylinder bottoms, one end, and it is more bigger that the external diameter of the aperture in hole 311 and penholder 10 matches, and is arranged so that like this that piston 32 is unlikely to skid off from sleeve 31.In the cylinder chamber of sleeve 11, accommodate cleaning agent, by promoting penholder 10, can drive piston 32 slippage in sleeve 31, the cleaning agent of storing in sleeve 31 cavitys is squeezed out.
The other end of sleeve 31 arranges end cap 33, and described end cap 33 leading portion external diameters and sleeve 31 internal diameters match, and back segment external diameter and sleeve 31 external diameters match, and the leading portion of end cap 33 is inserted in sleeve 31 and forms and be sealed and matched.Being provided with of end cap 33 is beneficial to reusing of this device, after cleaning agent uses, takes off end cap 33, can in the inner chamber of sleeve 31, add cleaning agent easily; In addition, because penholder 10 is connected with piston 32, if both adopt plug-in type to be fixedly connected with, so, when changing penholder 10, penholder 10 is inserted in piston 32 can produce certain thrust, now, take off end cap 33, and prop up piston 32 from end cap 33 these one end, be more conducive to the insertion of penholder 10.
The liquid outlet 331 that is communicated with sleeve 31 inner chambers is set on described end cap 33, because cleaning agent itself has certain tension force, when the aperture of liquid outlet 331 hour, if there is no the promotion of piston 32, even if arrange, do not stop up 35, cleaning agent can not flow out from liquid outlet 331 yet.
As preferred version of the present utility model, guarantee the sealing of 31, piston 32 and sleeve, the face place fitting at both is provided with sealing ring 34, sleeve 31 barrels own are not very thick, therefore comparatively ideal scheme is: described piston 32 outside peripheries are provided with annular groove, are furnished with sealing ring 34 in annular groove.
More preferably, described liquid outlet 331 is arranged on the center of end cap 33, and liquid outlet 331 places are provided with adaptive with it obstruction 35; One end of described obstruction 35 is column and forms plug-in type sealeds with liquid outlet 331 and coordinates, and it is spherical that the other end is, and is convenient to stop up 35 take off/insert.
