DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-5The subway car air purification and refrigeration device comprises a purification channel 1, two purification plates 2 are slidably installed in the purification channel 1 through slots, a pull-out opening matching with the two purification plates 2 is opened on the outer wall of the purification channel 1, and sealing gaskets 3 matching with the pull-out opening are fixedly installed on the outer walls of the two purification plates 2. Both sealing gaskets 3 are made of vulcanized rubber. Vulcanized rubber refers to vulcanized rubber, which has the characteristics of not being sticky and not easy to break, and also has high elasticity, heat resistance, tensile strength and insolubility in organic solvents, etc. Handles 4 are fixedly installed on the outer walls of the two purification plates 2, and multiple slow flow plates 5 are fixedly installed in the purification channel 1, each slow flow plate 5 is tilted, and two spring telescopic rods 7 are fixedly installed in the purification channel 1 through a supporting mechanism. The supporting mechanism comprises a supporting plate 6 fixedly installed on the inner wall of the purification channel 1, and the spring telescopic rod 7 is fixedly installed on the outer wall of the supporting plate 6.

[0027] The telescopic ends of the two spring telescopic rods 7 are commonly fixedly connected with an intercepting mesh plate 8, and an upper top groove is provided on the upper end surface of the intercepting mesh plate 8, and an upper top pin 10 is slidably installed inside the upper top groove through an upper top mechanism. The upper top mechanism includes an upper top spring 9 installed inside the upper top groove, and the two ends of the upper top spring 9 are elastically connected to the inner wall of the upper top groove and the bottom wall of the upper top pin 10 respectively, and the outer wall of the upper top pin 10 is provided with an inclined surface, and the inner wall of the purification channel 1 is provided with an extrusion groove 11 that cooperates with the inclined surface of the upper top pin 10, and the upper end surface of the purification channel 1 is provided with a fixed through hole 12 connected with the interior, and a dial plate 13 is fixedly installed on the outer wall of the upper top pin 10, and a movable opening that cooperates with the dial plate 13 is provided on the outer wall of the intercepting mesh plate 8, and the outer wall of the purification channel 1 is fixedly connected with a cold air duct 15 through a connecting mechanism. The connecting mechanism includes two connecting rods 14 fixedly installed on the outer wall of the purification channel 1, and the ends of the two connecting rods 14 are fixedly connected to the outer wall of the cold air duct 15.

[0028] The outer wall of the cold air duct 15 is provided with multiple air outlets connected to the interior, and a connecting pipe 16 connected to the interior is fixedly installed on the outer wall of the cold air duct 15. Two storage boxes 18 and two adding pumps 20 are fixedly installed on the outer wall of the purification channel 1 through a connecting mechanism. The connecting mechanism includes a connecting plate 17 fixedly installed on the outer wall of the purification channel 1. The two storage boxes 18 and the two adding pumps 20 are fixedly installed on the upper end surface of the connecting plate 17. One of the storage boxes 18 is filled with disinfectant, and the other storage box 18 is filled with fragrance. The upper end surfaces of the two storage boxes 18 are provided with filling ports connected to the interior, and the inner walls of the two filling ports are threadedly installed with sealing plugs 19. The inlet pipes of the two adding pumps 20 extend to the interior of the storage boxes 18 on the same side, respectively, and the outlet pipes of the two adding pumps 20 are connected to the cold air duct 15.

[0029] When the utility model is used, the interception mesh plate 8 is first pushed forward so that the interception mesh plate 8 squeezes the spring telescopic rod 7 when it moves, and the inclined surface of the upper ejector pin 10 can contact the extrusion groove 11 during the movement, thereby the upper ejector pin 10 is forced to move downward inside the upper ejector groove and squeeze the upper ejector spring 9. As the interception mesh plate 8 continues to move inside the purification channel 1, when the upper ejector pin 10 moves to the fixed through hole 12, the upper ejector pin 10 loses its extrusion and can move to the fixed through hole 12 under the elastic action of the upper ejector spring 9. Thus, the interception mesh plate 8 can be fixed, and the purification channel 1 can extract the air inside the car by cooperating with the induced draft fan, and the interception mesh plate 8 can intercept and filter larger debris in the air;

[0030] When air enters the purification channel 1, the two purification plates 2 slidably installed inside the purification channel 1 can purify the air. During purification, the multiple slow flow plates 5 inclined inside the purification channel 1 slow down the speed of air circulation, thereby increasing the residence time of air in the purification channel 1, thereby improving the purification effect of the purification plate 2 on the air. The sealing gasket 3 can increase the sealing between the purification plate 2 and the pull-out opening. When it is necessary to clean the purification plate 2, the purification plate 2 can be moved out of the pull-out opening for cleaning by the handle 4. When it is necessary to clean the interception mesh plate 8, the plate 13 can be moved through the mobile opening to drive the upper ejector pin 10 to move downward, thereby moving the upper ejector pin 10 out of the fixed through hole 12. At this time, the spring telescopic rod 7 releases its elastic potential energy to drive the interception mesh plate 8 to move out of the purification channel 1, and then the inner and outer walls of the interception mesh plate 8 can be cleaned;

[0031] Twisting the sealing plug 19 can release the closure of the filling port, and then the disinfectant and the fragrance can be added to the two storage boxes 18 respectively through the filling port. When the air conditioner cools the car compartment through the cooperation of the connecting pipe 16 and the cold air duct 15, one of the adding pumps 20 can pump the fragrance into one of the storage boxes 18, and then pump the fragrance out into the cold air duct 15. At this time, the cold air can mix the fragrance and be discharged through multiple air outlets in the cold air duct 15. In this way, fragrance can be added to the air inside the car during cooling, thereby eliminating the odor inside the car and increasing the comfort of riding. When the subway is in a suspension period, another adding pump 20 can pump the disinfectant into the other storage box 18, and the disinfectant can be mixed with the cold air in the cold air duct 15 and blown out, thereby disinfecting the interior of the car, thereby increasing the safety of passengers.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
