[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor belong to the scope of protection of the utility model.

[0021] Embodiment one

[0022] Please refer to Figures 1-4 The utility model provides the following technical scheme: a kind of elevator car ventilation machine, including elevator car body 1 and the ventilation machine 2 being equipped with on the top of elevator car body 1, ventilation machine 2 is close to the surface of one end of elevator car body 1 and is connected with air inlet pipe 3 and exhaust pipe 4 in relative symmetry, the inside of air inlet pipe 3 and exhaust pipe 4 is provided with first louver 5 and second louver 12 respectively, the outer wall of air inlet pipe 3 and exhaust pipe 4 is provided with recess 9 for the first louver 5 and second louver 12 to move out, and the top surface of first louver 5 and second louver 12 is connected with support rod 6.

[0023] In the preferred embodiment: first louver 5 is integrally connected between support rod 6 and second louver 12.

[0024] In the preferred embodiment: fixed block 7 in the shape of "L" is installed on the outer wall of ventilation machine 2, and electric rod 8 is installed on the top and bottom of fixed block 7.

[0025] In the preferred embodiment: the telescopic end of electric rod 8 is connected with the top surface of support rod 6, and support rod 6 is connected with ventilation machine 2 in a lifting manner through electric rod 8.

[0026] In the preferred embodiment: first louver 5 and second louver 12 are connected with air inlet pipe 3 and exhaust pipe 4 in a lifting manner through support rod 6 and electric rod 8.

[0027] In the preferred embodiment: first louver 5 and second louver 12 are connected with air inlet pipe 3 and exhaust pipe 4 in a lifting manner through support rod 6 and electric rod 8.

[0028] In addition, when the ventilation machine 2 is working, the air inlet pipe 3 is used to suck the elevator car body 1 into purification, and the air outlet pipe 4 is used to discharge the purified air into the elevator car body 1. Then, after the air flow passes through the air inlet pipe 3 and the air outlet pipe 4, it will be dispersed by the first louver 5 and the second louver 12. This design can adjust the angle of air flow, especially in the exhaust state, which can effectively avoid the direct impact of air flow on the inside of the elevator car body 1, thereby reducing the discomfort of the personnel in the elevator car body 1 caused by air flow.

[0029] Subsequently, the telescopic movement of the electric rod 8 connected to the power source can drive the supporting rod 6 to extend or retract, and at the same time, the supporting rod 6 drives the first louver 5 and the second louver 12 to move in the groove 9. This design facilitates the removal of the first louver 5 and the second louver 12 from the inside of the air inlet pipe 3 and the air outlet pipe 4. After the first louver 5 and the second louver 12 are damaged, the connection between the supporting rod 6 and the electric rod 8 can be disassembled for replacement. The telescopic height of the electric rod 8 satisfies the complete removal of the first louver 5 and the second louver 12 from the inside of the air inlet pipe 3 and the air outlet pipe 4. At the same time, the first louver 5 and the second louver 12 are in a sealed state inside the air inlet pipe 3 and the air outlet pipe 4, and the air flow will not be dispersed from the groove 9.

[0030] Example Two

[0031] Please refer to Figures 1-4 The same outer wall of the ventilation machine 2, the air inlet pipe 3 and the air outlet pipe 4 is connected with the mounting ear 10 in the shape of "L" at four corners. The surface of the mounting ear 10 is through-thread connected with the bolt 11.

[0032] In the preferred embodiment, the height of the mounting ear 10 is higher than the groove 9 but smaller than the air inlet pipe 3 and the air outlet pipe 4, and the air inlet pipe 3 and the air outlet pipe 4 are connected to the mounting hole at the top end of the elevator car body 1.

[0033] In the example, according to the description in Example One, the ventilation machine 2 is assembled at the top end of the elevator car body 1 by using the mounting ear 10 to form support, and then the air inlet pipe 3 and the air outlet pipe 4 are connected to the mounting hole at the top end of the elevator car body 1 for sealing. Subsequently, the bolt 11 is fastened to the top end of the elevator car body 1. This design can conveniently assemble at the top end of the elevator car body 1, and the height of the mounting ear 10 is higher than the groove 9 but smaller than the air inlet pipe 3 and the air outlet pipe 4, so it will not hinder the removal of the first louver 5 and the second louver 12 from the air inlet pipe 3 and the air outlet pipe 4.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
