Background technique

Taiwan Announcement No. 201914 "Mobile Indoor Sterilizer" patent case is to set the ultraviolet lamp on a movable body, which can irradiate bacteria indoors; but because the ultraviolet lamp is within a certain irradiation distance (about 150 cm) , has a bactericidal effect. And the ultraviolet lamp tube of this case is arranged on the fixed lamp holder body, and the range that can irradiate is fixed, and can't change the irradiating mode, has the narrow shortcoming of irradiating (sterilizing) range.

Secondly, the sterilizing line w of the existing ultraviolet lamps varies according to different power lamps. For a 10W lamp, the sterilizing line is 1.85; for 20W is 4.2; for 30W is 10.0; , then its sterilizing line is only 1.85×3=5.55, which is about half of a 30W sterilizing line. Therefore, according to the characteristics of the current ultraviolet lamps, installing a 30W lamp can almost double the irradiation efficiency of three 10W lamps; and the length of the 30W lamp is 893mm, and in order to increase its irradiation range, it needs to be configured horizontally. As a result, it is only suitable for places with fixed devices such as operating rooms, and is not conducive to mobile use in homes or offices, such as irradiating and sterilizing kindergarten classrooms with desks and chairs.

Therefore, the problem to be solved by the present invention is how to use it in homes or classrooms with the best irradiation efficiency and in a mobile manner.

Detailed ways

At first, referring to Fig. 1, shown in Fig. 2, the utility model comprises:

A base 1 is set to be movable, and the movable structure is a common prior art and will not be described in detail;

A skeleton 2 is erected on the base 1;

Several elongated extension arms 3, the inner ends of which are pivotally arranged on the platform 21 above the frame 2 with pivot joints 31, and the bottom is provided with telescopic rods or air rods 32 to support its expansion, on which there are The ultraviolet lamp tube 4, and each retractable arm 3 can be independently folded or unfolded in a horizontal state. The telescopic rod 32 includes an oil pressure rod or an air pressure rod or the like.

Furthermore, the frame 2 is provided with a clasp 22 at a predetermined position, which clasps and positions the retractable arm 3 in the folded state.

The pivoting device 31 of the above-mentioned retractable arm includes: a pivoting body 311 is pivotally arranged on a lug 313 fixed on the side of the platform 21 with a pivoting member 312, and the platform 21 above the pivoting body 311 is provided with an extending convex plate 314 , when the retractable arm 3 is unfolded in a horizontal state, it can be positioned against the top of the platform 21 .
