Abstract
The invention belongs to the multimedia teaching appliance field, and particularly discloses a projection curtain capable of automatically removing dust. The projection curtain comprises a housing, a curtain, a twyer, a dedusting bag, a rotation shaft installed inside the housing and a dedusting plate installed on the housing; one end of the curtain is fixedly connected to a scroll; one end of the dedusting plate is fixedly connected to the housing; the other end of the dedusting plate is in contact with the curtain; the dedusting plate, the housing and the curtain form a cavity which is of a triangular prism; the housing is provided with a support for installing the twyer; the twyer is fixedly installed on the support and arranged on one side of the cavity; and the dedusting bag is installed on the other side of the cavity. The invention is aimed to provide the projection curtain capable of automatically removing dust, which can prevent the effect from being affected by the dust.
Description
Technical field
The present invention relates to multimedia teaching apparatus field, be specifically related to a kind of projection screen of automatic dust removing.
Background technology
Indispensable apparatus during projection screen in college classroom instruction and business presentations, general employing can the curtain of automatic lifting.But the surface of projection screen in use can be glued and is covered with dust, the time one is long, and dust will be cumulative, thus affect the drop shadow effect of curtain, can be smudgy when watching.A kind of projection screen that dust can be avoided to affect the automatic dust removing of drop shadow effect of present urgent need.
Summary of the invention
The object of the present invention is to provide a kind of projection screen that dust can be avoided to affect the automatic dust removing of drop shadow effect.
The base case that this programme provides is: the projection screen of automatic dust removing, comprises shell, curtain, fan blower, dust settling pocket, installation rotating shaft in the enclosure and the dedusting plate be arranged on shell; Curtain one end is fixedly connected with spool, dedusting plate one end is fixedly connected with shell, the dedusting plate other end contacts with curtain, dedusting plate, shell and curtain form a triangular prism shaped cavity, shell is provided with the support for installing fan blower, fan blower to be fixedly mounted on support and to be positioned at the side of cavity, and dust settling pocket is fixedly mounted on the opposite side of cavity.
Principle of work and the advantage of this programme are: when rotating shaft works, curtain can rise and decline, in the process rise at curtain, declined, curtain meeting and dedusting plate produce relative motion, in motion process, the dust on curtain surface can be wiped off by dedusting plate, allows dust be separated with curtain.Because dedusting plate, shell and curtain form a triangular prism shaped cavity, fan blower is positioned at the side of cavity, and the dust in cavity can be blown to the opposite side of cavity by fan blower, and dust collects by the dust settling pocket of opposite side.Dedusting plate can allow the dust on curtain surface and curtain depart from the one hand; On the other hand the cavity that forms of dedusting plate and shell and curtain, can strengthen the work efficiency of fan blower, reach the object of automatic dust removing.And in the ascending and descending process of each curtain, can carry out dedusting to curtain, ensure in use, dust removal process was entered on the surface of curtain, reached the object avoiding dust to affect drop shadow effect.
Preferred version one: based on the preferred version of scheme, dedusting plate is provided with soft bristle.Soft bristle better can know the dust on curtain surface.
Preferred version two: the preferably preferred version of: the switch also comprising fan blower and spool, fan blower is electrically connected with same switch with spool.Fan blower only drives during curtain motion at spool and just starts working, fan blower also only needs to work when spool works, adopt same switch, can simplify the operation steps of user, reaching user only needs normally to start the object that spool just can know curtain surface dirt.
Preferred version three: the preferably preferred version of two: the web joint being provided with inclination between dedusting plate and soft bristle, upper side and the fan blower of web joint are adjacent.The web joint tilted can allow dust better from the upper side at fan blower place, moves to the comparatively downside at dust settling pocket place, the collection of more convenient dust settling pocket.
Accompanying drawing explanation
Fig. 1 is the structural representation of the projection screen embodiment of automatic dust removing of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: shell 1, curtain 2, fan blower 3, dust settling pocket 4, dedusting plate 5, web joint 6.
Embodiment is substantially as shown in Figure 1: the projection screen of automatic dust removing, comprises shell 1, curtain 2, fan blower 3, dust settling pocket 4, is arranged on the rotating shaft in shell 1 and is arranged on the dedusting plate 5 on shell 1; Curtain 2 one end is fixedly connected with spool, dedusting plate 5 one end is fixedly connected with shell 1, dedusting plate 5 other end contacts with curtain 2, dedusting plate 5, shell 1 and curtain 2 form a triangular prism shaped cavity, shell 1 is provided with the support for installing fan blower 3, fan blower 3 to be fixedly mounted on support and to be positioned at the side of cavity, and dust settling pocket 4 is fixedly mounted on the opposite side of cavity.The projection screen 2 of automatic dust removing also comprises the switch of fan blower 3 and spool, and fan blower 3 and spool are same switch.Dedusting plate 5 is provided with soft bristle.Be provided with the web joint 6 of inclination between dedusting plate 5 and soft bristle, web joint 6 side mutually close with fan blower 3 is higher.
During concrete use: when rotating shaft works, curtain 2 can rise and decline, in the process rise at curtain 2, declined, curtain 2 meeting and dedusting plate 5 produce relative motion, in motion process, the dust on curtain 2 surface can be wiped off by dedusting plate 5, allows dust be separated with curtain 2.Because dedusting plate 5, shell 1 and curtain 2 form a cavity, fan blower 3 is positioned at the side of cavity, and the dust in cavity can be blown to the opposite side of cavity by fan blower 3, and dust collects by the dust settling pocket 4 of opposite side.Dedusting plate 5 one aspect can allow the dust on curtain 2 surface and curtain 2 depart from; The cavity that another aspect dedusting plate 5 is formed with shell 1 and curtain 2, can strengthen the work efficiency of fan blower 3, reach the object of automatic dust removing.And in the ascending and descending process of each curtain 2, can carry out dedusting to curtain 2, ensure in use, dust removal process was entered on the surface of curtain 2, reached the object avoiding dust to affect drop shadow effect.
Soft bristle better can know the dust on curtain 2 surface.Fan blower 3 is only just started working when spool drives curtain 2 to move, fan blower 3 also only needs to work when spool works, adopt same switch, can simplify the operation steps of user, reaching user only needs normally to start the object that spool just can know curtain 2 surface dirt.The web joint 6 tilted can allow dust better from the upper side at fan blower 3 place, moves to the comparatively downside at dust settling pocket 4 place, the collection of more convenient dust settling pocket 4.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the embodiment in instructions etc. record the content that may be used for explaining claim.
