Detailed Description

The present invention will be described in further detail with reference to embodiments shown in the drawings.

As shown with reference to figures 1-4,

a dustproof mechanism of a laboratory ventilation system comprises a shell 1 and a ventilation hole 2 arranged on the shell 1, wherein the shell 1 comprises a main body 3 and a dustproof cover 4 arranged on the main body 3, a movable exhaust duct 5 is arranged on the main body 3, and the position of the exhaust duct 5 corresponding to the main body 3 is matched with the ventilation hole 2 so as to exhaust air through the ventilation hole 2; the dust cover 4 is movably connected to the main body 3 to cooperate with the main body 3 to form or remove the covering of the exhaust duct 5.

In a specific embodiment, the main body 3 can be provided with a groove for accommodating the exhaust pipe 5, the exhaust pipe 5 can be accommodated in the groove, and then the dust cover 4 can move to cover the exhaust pipe 5, so that the dust prevention effect is achieved. Wherein exhaust pipe 5 cooperates with ventilation hole 2, can realize the effect of airing exhaust to have the extension effect, can utilize exhaust pipe 5 to aim at the position that needs the air exhaust, discharge harmful gas, let the experimentation safer.

Specifically, the dust cap 4 can be moved in the following two ways:

A. the movable mode of the dust cover 4 is sliding, the covering and the opening of the groove are realized by sliding on the main body 3 along the length direction, and the exhaust duct 5 can be taken out after the opening and then is aligned to the position needing exhaust to work.

B. The active mode of shield 4 is the form of upset, and one side articulates on main part 3 to set up along the length direction of main part 3, can cover and open exhaust pipe 5 through the form of upset. After the dust cover 4 is turned outwards, the dust cover is opened, and the exhaust pipe 5 is taken out to be aligned to the position needing exhaust to work.

Specifically, in the mode a, the dust cap 4 may be slidably connected to the main body 3 by a key-groove fit. The positions of the keys and the grooves can be respectively arranged on the dust cover 4 and the main body 3, and the keys arranged on the dust cover 4 and the main body 3 can form sliding fit. Preferably, the key may be provided on the dust cap 4, which can reduce the thickness requirement for the dust cap 4 and thus control the cost.

In the mode B, the main body 3 is further provided with a lamp tube or a lamp strip 6, and the lamp tube or the lamp strip 6 is arranged on the main body 3 and is located between the main body 3 and the dust cover 4. Fluorescent tube and lamp area 6 set up the position between main part 3 and shield 4, can realize the dustproof effect to light and lamp area 6 with the help of shield 4.

Preferably, a side of the dust cover 4 facing the lamp tube or the lamp strip 6 is a reflective surface 41 for reflecting light of the lamp tube or the lamp strip 6. Light and lamp area 6 are reflected light through the reflective surface 41 of shield 4, make it can reflect the laboratory bench, can have better illuminating effect to can solve the problem that the position illumination of 6 installations in lamp area can receive the influence, can adapt to the mounting means in various lamp areas 6.

In further cooperation, the light reflecting surface 41 is a matte surface for forming diffuse reflection. Light is reflected through the form of diffuse reflection, so that the light irradiation is softer, and the irradiation range can be enlarged.

Of course, optionally, with the above scheme, a lamp tube or a lamp strip 6 for illumination may be disposed at a position on the main body 3 facing downward and exposed. Can provide brighter illuminating effect through this lamp area 6, select according to the experimental personnel actual needs, when the higher illuminating effect of needs, can select lamp area 6 and the lamp area 6 of high illuminating effect of opening the diffuse reflection effect, both cooperations provide local high illuminating effect, whole big irradiation range.

The dust cover 4 can be turned over manually. However, the mode of turning the dust cover 4 by the pulling rope can be improved, and the dust cover 4 can be turned upwards by pulling the pulling rope by hanging the pulling rope on the dust cover 4. The main body 3 may be modified to be electrically controlled, and specifically, the main body 3 is provided with an electric driving member 7 for driving the dust cap 4 to rotate, and a detection member 8 for detecting that the dust cap 4 is rotated to the proper position, and the detection member 8 is linked with the electric driving member 7 and controls the electric driving member 7 to stop operating.

The dust cover 4 is driven by the electric driving part 7 to turn over, meanwhile, the detection part 8 is matched for feedback, and the electric driving part 7 is controlled to stop driving after the detection part 8 detects that the dust cover 4 turns over in place. The specific detection component 8 can adopt infrared detection, laser ranging, trigger switch and the like. The electric driving part 7 may be a motor, and the main body 3 may be provided with a plurality of motors to drive the dust cap 4 synchronously. The specific driving mode can be that the hinged shaft of the dust cover 4 is driven and is transmitted by means of gear engagement. And the detection position of the detection part 8 can be covered in position or opened in position. The detection component 8 may be arranged at a corresponding position by a person skilled in the art according to a required detection manner, and the specific arrangement position is selected by the person skilled in the art according to requirements, which is not described herein in detail.

And specifically, the detection part 8 of this scheme can be as follows, and detection part 8 adopts micro-gap switch, and a stay cord is connected to this micro-gap switch's preforming, and the one end and the preforming of this stay cord are connected, and the other end is connected with shield 4, and when shield 4 overturned when targetting in place, the stay cord was pulled down the preforming and was triggered micro-gap switch.

The shape of the dust cover 4 needs to be matched with the main body 3, and a space capable of accommodating the exhaust pipe 5 needs to be formed between the dust cover 4 and the main body 3, so that the dust cover 4 is generally arc-shaped, the detection is difficult to realize by matching the shape with a conventional detection part 8, for example, the dust cover 4 is difficult to match and detect when being turned upwards, the pull rope is connected onto the dust cover 4, the pull rope can be pulled by turning the dust cover 4 upwards, the pressing sheet can be pulled finally along with the pulling of the pull rope, the pressing sheet triggers a button of a microswitch, the in-place feedback is achieved, and the electric driving part 7 is controlled to stop driving; in the same way, in-place feedback can be realized when the dust cover 4 is turned downwards.

Certainly, the detection component 8 may also adopt a hall switch, and the turnover degree of the dust cover 4 is detected in a magnetic induction manner, for example, the magnet is attached to the dust cover 4, the hall switch is installed on the main body 3, when the dust cover 4 is opened in place, the magnet approaches the dust cover 4, so that the hall switch is fed back in place, and at this time, the electric driving component 7 stops driving; in the same way, in-place feedback can be realized when the dust cover 4 is turned downwards.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
