First embodiment
Details refer to Fig. 1, and Fig. 1 shows the dust guard 100 that this utility model first embodiment provides, this dust-proof dress
Put 100 for scialyscope 200.Dust guard 100 includes dust-proof screen component 110, fixed seat 120, sensing device 130 and controller
140.
Dust-proof screen component 110 is used for preventing dust from entering inside scialyscope 200, and dust-proof screen component 110 is arranged on scialyscope
The inner side of 200 air inlet, dust-proof screen component 110 includes Air Filter 112 and dust-proof screen frame 111, Air Filter 112 and dust-proof screen frame
111 shape size coupling, Air Filter 112 is fixed in dust-proof screen frame 111.
Air Filter 112 is used for filtering dust, and Air Filter 112 can be one layer of sponge.Preferably, as shown in Fig. 2 Air Filter
112 include double-level-metal stratum reticulare 113 and spongy layer 114, and spongy layer 114 is located between double-level-metal net.Double-level-metal stratum reticulare 113
It is fixed together by two dust-proof screen frames 111 with spongy layer 114, spongy layer 114 is used for absorbing and dust, double-level-metal stratum reticulare
113 are used for fixing and protect spongy layer 114.Preferably, double-level-metal stratum reticulare 113 and spongy layer 114 and two dust-proof screen frames 111
It is detachably connected, convenient disassemble each layer is cleaned and changed spongy layer 114.Preferably, metal net layer is stainless (steel) wire
Layer, stainless steel material is prevented from this metal net layer and gets rusty or by air corrosion, prevents Air Filter 112 from deforming, makes Air Filter
112 service life is longer.
Air Filter 112 is to be other geometry such as the network structure of circular port arrangement or rectangle
The network structure of hole arrangement.Here the shape and structure of Air Filter 112 is not defined.
The size of dust-proof screen component 110 and the size of the air inlet side wall 220 of scialyscope 200 applied
Join, the area of specially dust-proof screen component 110 is more than or equal to the area of air inlet side wall 220, cover air inlet side wall comprehensively
220, so that omnibearing prevent dust from entering scialyscope 200.
Fixed seat 120 is used for fixing dust-proof screen component 110, and dust-proof screen component 110 can be fixed in this fixed seat 120,
In fixed seat 120, the position of corresponding dust-proof screen component 110 side is provided with first through hole 121, and first through hole 121 is used for placing sensing
Device 130.
Sensing device 130 is used for experiencing the information that dust-proof screen component 110 is arranged in this fixed seat 120, and this is believed
Breath is converted into the signal of telecommunication or other signal outputs to controller 140.Sensing device 130 is arranged on above-mentioned fixed seat 120
In first through hole 121, sensing device 130 exposes fixed seat 120 through this throughhole portions, so that when dust-proof screen component 110 is installed
When sensing device 130 can contact with dust-proof screen component 110.The opposite side of sensing device 130 is connected with controller 140.

When dust-proof screen component 110 is installed in fixed seat 120, pressure transducer detects the gravity of dust-proof screen component 110,
And the first activation signal or the second activation signal are produced according to the magnitude range of power.When controller 140 receives the first signal,
Control scialyscope 200 to point out dust-proof screen component 110 not install, can be specifically to show to be similar on the screen being projected out " to prevent
Dirt net is not mounted to position, please check " printed words；When controller 140 receives the second activation signal, controller 140 can control
Scialyscope 200 display Air Filter has connected it is also possible to not show any prompting.
Wherein, this pressure transducer pre-sets corresponding two signals of two pressure limits, by testing in advance, when anti-
When dirt screen component 110 is arranged in fixed seat 120 but does not install, for example dust-proof screen frame 111 has a clamp with fixed seat 120
Angle, or install not in place when, the power that pressure transducer receives is less, test obtain first pressure scope；When dust-proof
When screen component 110 is installed in order in fixed seat 120, test obtains corresponding second pressure scope.First pressure scope
Corresponding first activation signal, second pressure scope corresponds to the second activation signal.
The dust guard 100 that first embodiment provides is applied to operation principle during scialyscope 200：
It is as a example microswitch 131 by the sensing device 130 of dust guard 100, when dust preventing component is not installed at fixed seat
When 120, microswitch 131 is in opening, and controller 140 receives the signal of microswitch 131 unlatching, controls scialyscope
The 200 dust-proof screen components 110 of prompting are not connected with.When dust preventing component is installed, microswitch 131 is in closure state, controller 140
Receive the signal of microswitch 131 closing, control scialyscope 200 to point out dust-proof screen component 110 to connect or do not pointed out.
The dust guard 100 that this utility model first embodiment provides is used in scialyscope 200, does not pacify in scialyscope 200
During dress dust preventing component, realization can point out dust-proof screen component 110 to be not connected with scialyscope 200.
