DETAILED DESCRIPTION OF EMBODIMENTS

[0019] The present utility model will be described in further detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0020] As shown in FIGS. 1-3:

[0021] A three-door interlocking air shower comprises an air shower box 1. A front door panel 11, a left door panel 12 and a right door panel 13 are respectively provided at the front end, the left end and the right end of the air shower box 1. A first electronic interlocking device 14, a second electronic interlocking device 15 and a third electronic interlocking device are provided on the air shower box 1. A first lock groove cooperating with the first electronic interlocking device 14 is provided on the front door panel 11, a second lock groove cooperating with the second electronic interlocking device 15 is provided on the left door panel 12, and a third lock groove cooperating with the third electronic interlocking device is provided on the right door panel 13. A plurality of fans 2 are provided at the top end of the air shower box 1, a primary filter 3 is provided at a lower side of each fan 2, a breathable dust-isolating plate 4 is provided at a lower side of the primary filter 3, and a first air-outlet assembly 5 and a second air-outlet assembly 6 are respectively provided on left and right sides below the breathable dust-isolating plate 4. An infrared emitter 7 is fixed to one side of the first air-outlet assembly 5, and an infrared receiver 8 opposite to the infrared emitter 7 is fixed to one side of the second air-outlet assembly 6. The infrared emitter 7 and the infrared receiver 8 cooperate to sense whether a person or an article passes therebetween. The infrared emitter 7 continuously emits infrared rays; when there is no obstruction between the infrared emitter 7 and the infrared receiver 8, the infrared receiver 8 can receive the optical signal; when a person or an article obstructs between the infrared emitter 7 and the infrared receiver 8, the infrared receiver 8 cannot receive the optical signal, whereby the infrared receiver 8 feeds the signal back to a corresponding control system, and the control system instructs the fan 2, the first blower 51 and the second blower 61 at corresponding positions to operate.

[0022] Preferably, a glass viewing window 91 and a handle 92 are provided on each of the front door panel 11, the left door panel 12 and the right door panel 13.

[0023] Preferably, each of the first electronic interlocking device 14, the second electronic interlocking device 15 and the third electronic interlocking device consists of a control panel and an electromagnetic lock, an indicator lamp is provided on the control panel, and the first electronic interlocking device 14, the second electronic interlocking device 15 and the third electronic interlocking device are interlocked under the control of 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 are off, indicating that these door panels cannot be opened, and 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, while the indicator lamps on the corresponding control panels light up, indicating that the other two door panels can be opened.

[0024] Preferably, the primary filter 3 comprises an outer frame 31, and a first metal mesh 32, a porous sponge filter element 33 and a second metal mesh 34 fixed to an inner side of the outer frame, and the porous sponge filter element 33 can adsorb most of the dust in the gas.

[0025] Preferably, a plurality of truncated-cone-shaped through holes 41 are provided on the breathable dust-isolating plate 4, and a plurality of arc-shaped grooves 42 are further provided at an upper end of the breathable dust-isolating plate 4. When the fans 2 operate, gas passes through the truncated-cone-shaped through holes 41; when the gas passes through the primary filter 3, the primary filter 3 can adsorb most small-particle-size dust, while large-particle dust remains on a lower end face of the primary filter 3 under the action of wind pressure. When the fans 2 stop operating, the large-particle dust falls; since the diameter of the lower end of each truncated-cone-shaped through hole 41 is greater than that of the upper end, only a very small amount of large-particle dust returns to the air shower through the truncated-cone-shaped through holes 41, and a large amount of large-particle dust falls into the arc-shaped grooves 42 and is collected. Edges of the breathable dust-isolating plate 4 are fixed to an inner top end of the air shower box 1 by screws, facilitating disassembly and cleaning.

[0026] Preferably, the first air-outlet assembly 5 comprises a first blower 51, a first air pipe 52 connected to an air outlet of the first blower 51, and a plurality of first nozzles 53 connected to the first air pipe 52.

[0027] Preferably, the second air-outlet assembly 6 comprises a second blower 61, a second air pipe 62 connected to an air outlet of the second blower 61, and a plurality of second nozzles 63 connected to the second air pipe 62.

[0028] The above embodiments only illustrate 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 those of ordinary skill in the art may make various modifications and improvements without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, the patent protection scope of the present utility model shall be subject to the appended claims.
