Abstract

The utility model relates to the technical field of an ultraviolet-ray photosensitive machine, particularly an ultraviolet-ray photosensitive machine which has the advantages of simple and convenient operation and safe use. The utility model comprises a supporting frame, an ultraviolet-ray emitting lamp tube and a spotlight body, wherein, the ultraviolet-ray emitting lamp tube is arranged in the spotlight body; the spotlight body is fixed on the supporting frame, and the exterior of the spotlight body is also provided with a rotatable light shielding hood; the spotlight body is also connected with an exhaust fan of which the exhaust opening is opened into the spotlight body. After using the structure, if operators stop using ultraviolet-ray photoreception temporary in the process of use, ultraviolet-ray can be shielded through rotating the light shielding hood, and the operators are not damaged by light; when the operators need use ultraviolet-ray photoreception, the light shielding hood is moved away from the front of the spotlight body through rotating the light shielding hood so as to enable the light to be emitted again, and thus, a power supply of the ultraviolet-ray emitting lamp tube need not be cut off. Simultaneously, the exhaust fan can discharge heat arranged in the spotlight body in time, lower the temperature of the spotlight body, and the condition that equipment is damaged caused by high temperature is avoided.

Description

The UV-radiation-sensitive machine

Technical field:

This utility model relates to UV-radiation-sensitive machine technology field, refers in particular to a kind of UV-radiation-sensitive machine easy and simple to handle, safe in utilization.

Background technology:

Present UV-radiation-sensitive machine mainly comprises ultraviolet emission fluorescent tube and condensing body, its middle-ultraviolet lamp emission fluorescent tube is placed in the condensing body, after ultraviolet emission fluorescent tube energized, will produce the ultraviolet high light, by condensing body light is reflected, gathering needs on sensitization or the germ-resistant object.Owing to when ultraviolet acts directly on human body, will damage the skin of human body,, make it to extinguish so when not using, need cut off the power supply of ultraviolet emission fluorescent tube usually.But there is certain deficiency in this mode, often needs aborning constantly to use the UV-radiation-sensitive machine, if frequent Switching Power Supply is easy to cause the damage of ultraviolet emission fluorescent tube, or is reduced its service life.In the process of using, will produce a large amount of heats in the condensing body in addition,, then damage equipment easily as untimely eliminating.

Summary of the invention:

The purpose of this utility model is to provide a kind of UV-radiation-sensitive machine easy and simple to handle, safe in utilization.

This utility model is achieved by the following technical solution: it comprises support, ultraviolet emission fluorescent tube, condensing body, and ultraviolet emission fluorescent tube places in the condensing body, and condensing body is fixed on the support, and condensing body also is provided with rotatable shade outward; Also be connected with an exhaust fan on the condensing body, and the air vent of this exhaust fan leads in the condensing body.

Described shade rotates shade relatively by two to be formed, and shade one end is set on the axle respectively; Axle is connected on the support between two connecting plates; Two mutual meshed gears also are set on the axle respectively, and this pitch wheel is separately fixed on the shade; Be installed in a driven wheel on the rack connecting plate and an engagement in above-mentioned two meshed gears, this driven wheel is rotated by driver drives.

After adopting this structure, in use as need temporarily stop using UV-radiation-sensitive, can be by the rotation shade, be located at condensing body before, form the cover body of a shield lights, UV-preventing is lived, make the operator not injured by light; When waiting need to use, rotate the refractive power cover again, it is moved before the condensing body come, light emits again, so just need not cut off the power supply that ultraviolet is launched fluorescent tube.Exhaust fan can be discharged the intravital heat of optically focused timely simultaneously, reduces its temperature, avoids occurring causing owing to temperature is too high that the situation of equipment damage occurs.

Description of drawings:

Below in conjunction with accompanying drawing this utility model is further described:

Fig. 2 is a shade of the present utility model axonometric chart when opening;

Fig. 3 is this utility model partial structurtes sketch maps.

The specific embodiment:

See accompanying

drawing

1,2,3, this utility model comprises: support 1, ultraviolet emission fluorescent tube 2, condensing body 3,

shade

41,42, exhaust fan 5 and driver 6.

Support 1 main body is " Y " shape, and its upper end is connected with a plate 11, and axle 411,421 is connected between two connecting plates 11.Ultraviolet emission fluorescent tube 2 places in the condensing body 3, and condensing body 3 is fixed on the support 1 by linking arm 12.

Condensing body 3 inwalls are reflecting metal, by the moulding of its depression ultraviolet are launched the light-ray condensing that fluorescent tube 2 sends, to strengthen the intensity of light.Condensing body 3 outer two

shades

41,42 that are provided with,

shade

41,42 1 ends are set in respectively on the axle 411,421, two mutual meshed gears 412,422 also are set in respectively on the axle 411,421, and this pitch wheel 412,422 is separately fixed on the

shade

41,42, be installed in an engagement in driven wheel 61 and above-mentioned two meshed gears 412,422 on support 1 connecting plate 11, this driven wheel 61 is by driver 6 driven rotary.Shade 41 is slightly larger than shade 42, and both can produce coincidence when rotating to certain position like this, prevents that light from by penetrating in the slit between two

shades

41,42, making the better effects if of shield lights.

Also be connected with an exhaust fan 5 on the condensing body 3, the QI KOU 51 of this exhaust fan 5 is led in the condensing body 3, and QI KOU 51 is over against ultraviolet emission fluorescent tube 2, so that radiating effect reaches best.

Bottom at support 1 also is equipped with roller 13, utilizes roller 13 easily this equipment to be moved to appointed positions.

In using process of the present utility model, temporarily stop using UV-radiation-sensitive as need, can drive driven wheel 61 rotations by control driver 6, thereby driven wheel 412 or gear 422,

shade

41,42 is rotated relatively, be located at condensing body 3 before, form the cover body of a shield lights, UV-preventing is lived, make the operator not injured by light; When waiting to need to use, rotate

refractive power cover

41,42 again, it is come from condensing body 3 preceding moving, light emits again, so just need not cut off the power supply of ultraviolet emission fluorescent tube 2.Exhaust fan 5 can be discharged the heat in the condensing body 3 timely simultaneously, reduces its temperature, avoids occurring causing owing to temperature is too high that the situation of equipment damage occurs.
