DETAILED DESCRIPTION OF EMBODIMENTS

[0021] The present utility model is described in further detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0022] As shown in FIGS. 1-7:

[0023] A three-door electronic-interlocking pass-through box comprises a box body 1. The box body 1 has a first opening 11, a second opening 12 and a third opening 13; the outer side of the first opening 11 is a clean area, the outer side of the second opening 12 is a non-clean area, and the outer side of the third opening 13 is a clean area. A first door panel 14, a second door panel 15 and a third door panel 16 are provided on the first opening 11, the second opening 12 and the third opening 13 respectively. A first electronic interlocking device 2, a second electronic interlocking device 3 and a third electronic interlocking device are provided on the box body 1; a first lock groove matched with the first electronic interlocking device 2 is provided on the first door panel 14, a second lock groove matched with the second electronic interlocking device 3 is provided on the second door panel 15, and a third lock groove matched with the third electronic interlocking device is provided on the third door panel 16. An ultraviolet germicidal lamp 4 is provided at an upper end inside the box body 1, and ultraviolet rays emitted by the ultraviolet germicidal lamp 4 have a very good killing effect on bacteria. A cavity is provided at the bottom of the box body 1, and an ozone generator 5 is provided in the cavity; air holes 17 communicating with the cavity are provided at the bottoms of the inner sides of the first opening 11, the second opening 12 and the third opening 13. Ozone generated by the ozone generator 5 can be delivered into the box body 1 through the air holes 17, and ozone has a relatively good sterilization effect and can reduce bacterial contamination of the two clean areas to a certain extent.

[0024] Preferably, a first photoelectric sensor 6 is provided at the inner side of the first opening 11, a first light shielding plate 7 corresponding to the first photoelectric sensor 6 is provided at the inner side of the first door panel 14, a second photoelectric sensor is provided at the inner side of the second opening 12, a second light shielding plate corresponding to the second photoelectric sensor is provided at the inner side of the second door panel 15, a third photoelectric sensor is provided at the inner side of the third opening 13, and a third light shielding plate corresponding to the third photoelectric sensor is provided at the inner side of the third door panel 16. Taking the first photoelectric sensor 6 as an example, after the first door panel 14 is opened, the first light shielding plate 7 leaves the light-shielding area of the first photoelectric sensor 6, and the first photoelectric sensor 6 can receive a light signal, so that the ozone generator 5 can be controlled to start. The ozone generator 5 generates ozone, which has a relatively good sterilization effect and can reduce bacterial contamination of the clean area to a certain extent.

[0025] Preferably, each of the first electronic interlocking device 2, the second electronic interlocking device 3 and the third electronic interlocking device consists of a control panel and an electromagnetic lock, the control panel is provided with an indicator lamp, and the first electronic interlocking device 2, the second electronic interlocking device 3 and the third electronic interlocking device are controlled for interlocking by an integrated circuit. The interlocking principle is as follows: when one of the door panels is opened, the indicator lamps on the control panels corresponding to the other two door panels do not light up, indicating that these door panels cannot be opened, and at the same time the electromagnetic locks act to realize interlocking. When this door panel is closed, the electromagnetic locks on the control panels corresponding to the other two door panels start to operate, and at the same time the indicator lamps on the corresponding control panels light up, indicating that the other two door panels can be opened.

[0026] Preferably, a glass transparent window 81 is provided in the middle of each of the first door panel 14, the second door panel 15 and the third door panel 16.

[0027] Preferably, a handle 82 is further provided on the outer side of each of the first door panel 14, the second door panel 15 and the third door panel 16.

[0028] The above embodiments only express one embodiment of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as limiting the patent scope of the present utility model. It should be noted that, for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can be made, all of which fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
