[0002] As an essential tool for commercial housing residents to enter and exit floors, the average number of times a resident takes the elevator per day is at least about four times. When residents take the elevator, there will be body odor, sweat odor and other odors remaining in the elevator car. Since the elevator car door is closed during standby, it is difficult to discharge the odors in the elevator car, which affects the riding experience of residents. Some elevator cars are equipped with exhaust fans or blowers at the top for ventilation. This exhaust method can only exhaust when the elevator door is open, and the exhaust effect is very small. In view of this, the present utility model is proposed. Content of the Utility Model

[0020] The following details the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0021] Please refer to Figures 1 - 3 , Figure 1 It is a three - dimensional structure schematic diagram of the new fan system provided by the embodiment of the present utility model installed on the car; Figure 2 It is an exploded structure schematic diagram of the new fan system provided by an embodiment of the present utility model installed on the car; Figure 3 It is an exploded structure schematic diagram of the new fan system provided by an embodiment of the present utility model. The new fan system 1 of the present utility model is used to be installed on the elevator car 2 for ventilation of the car 2. The new fan system 1 includes a support component and an exhaust component. The support component includes an installation bottom plate 11 and an installation cover plate 12. The exhaust component includes a fan 13, a first exhaust duct 14, and a second exhaust duct 15. The installation bottom plate 11 is installed on the top of the car 2. The fan 13 is installed on the upper surface of the installation bottom plate 11. The first exhaust duct 14 is communicated with the air inlet of the fan 13. The second exhaust duct 15 is communicated with the air outlet of the fan 13. The installation cover plate 12 is installed on the installation bottom plate 11 to cover the fan 13, the first exhaust duct 14, and the second exhaust duct 15. The installation bottom plate 11 is provided with an air inlet hole 111 corresponding to the position of the first exhaust duct 14. The side surface of the installation cover plate 12 is provided with an air outlet hole 123 corresponding to the position of the second exhaust duct 15.

[0022] By opening an air inlet hole 111 on the installation base plate 11, opening an air outlet hole 123 on the installation cover plate 12, and installing the fan 13 on the installation base plate 11, both ends of the first exhaust duct 14 are respectively communicated with the air inlet of the fan 13 and the air inlet hole 111 on the installation base plate 11, and both ends of the second exhaust duct 15 are respectively communicated with the air outlet of the fan 13 and the air outlet hole 123 on the installation cover plate 12. Thus, when the new type of fan system 1 is used to exhaust the car 2, by starting the fan 13, the fan 13 extracts the air in the car 2 through the first exhaust duct 14 and the air inlet hole 111, and discharges the extracted air through the second exhaust duct 15 and the air outlet hole 123, so as to achieve the ventilation effect of the car 2. Since the air extracted by the fan 13 is directly discharged from the air outlet hole 123 out of the car 2, even when the elevator door is closed, the ventilation of the car 2 can still be carried out, improving the exhaust effect of the car 2, reducing the peculiar smell in the car 2, and improving the elevator riding experience of residents.

[0023] In an embodiment of the present utility model, the installation cover plate 12 includes a cover plate 121 and a ventilation duct 122. The cover plate 121 covers the fan 13, the first exhaust duct 14 and the second exhaust duct 15 to protect and isolate the fan 13, the first exhaust duct 14 and the second exhaust duct 15 under the action of the cover plate 121, and at the same time can also reduce the noise generated when the fan 13 works, improving the experience of residents taking the elevator. The ventilation ducts 122 are symmetrically installed on opposite sides of the cover plate 121. Through holes are provided on the top surface of the ventilation ducts 122, and both sides of the ventilation ducts 122 along their length directions are open. The second exhaust duct 15 is communicated with the ventilation ducts 122 to allow the extracted air to enter the ventilation ducts 122 after passing through the second exhaust duct 15, and finally be discharged from the openings at both ends and the through holes at the top of the ventilation ducts 122 to improve the air quality in the car 2.

[0024] In an embodiment of the present utility model, the second exhaust ducts 15 are symmetrically arranged on both sides of the fan 13, and the two second exhaust ducts 15 are internally communicated. The air outlet holes 123 are opened on the inner wall of the ventilation ducts 122 for the second exhaust ducts 15 to communicate. The exhaust ducts on both sides are respectively communicated with the air outlet holes 123 of the ventilation ducts 122 on both sides, so that after the fan 13 extracts the air in the car 2, the air is discharged from the air outlet holes 123 on both sides, improving the exhaust effect of the fan 13.

[0025] In an embodiment of the present utility model, an exhaust profile 151 is provided at the end of the second exhaust duct 15. The exhaust profile 151 is perpendicular to the second exhaust duct 15 and extends along the length direction of the ventilation duct 122 and fits with the ventilation duct 122. The range of the air outlet holes 123 is adapted to the coverage range of the exhaust profile 151, so as to increase the exhaust space of the second exhaust duct 15 under the action of the exhaust profile 151, and cooperate with the air outlet holes 123 adapted to the coverage range of the exhaust profile 151 for exhaust, thereby improving the ventilation effect of the new fan system 1, improving the air quality in the car 2 and the experience of residents when taking the elevator.

[0026] In an embodiment of the present utility model, the first exhaust duct 14 includes a bent pipe 141 and an intake profile 142. One end of the bent pipe 141 is communicated with the air inlet of the fan 13, and the other end is communicated with the intake profile 142. The intake profile 142 fits on the mounting base plate 11 and is aligned with the air inlet holes 111. The range of the air inlet holes 111 is adapted to the coverage range of the intake profile 142, so as to increase the exhaust space of the first exhaust duct 14 under the action of the intake profile 142, and cooperate with the air inlet holes 111 adapted to the coverage range of the intake profile 142 to extract the air in the car 2, thereby improving the ventilation effect of the new fan system 1, improving the air quality in the car 2 and the experience of residents when taking the elevator.

[0027] In an embodiment of the present utility model, the exhaust assembly further includes a mounting bracket 16. The mounting bracket 16 is mounted on the mounting base plate 11, and the fan 13 is mounted on the mounting bracket 16. Under the support of the mounting bracket 16, the mounting height of the fan 13 is increased, which facilitates the connection between the first exhaust duct 14 and the air inlet holes 111 on the mounting base plate 11. Thus, the fan 13 can extract the air in the car 2 through the first exhaust duct 14 to achieve the effect of ventilating the car 2.

[0028] In an embodiment of the present utility model, an air inlet grille and an air outlet grille are respectively provided on the air inlet holes 111 and the air outlet holes 123 to filter dust and impurities in the air under the action of the air inlet grille and the air outlet grille, and prevent the first exhaust duct 14 and the second exhaust duct 15 from being blocked.

[0029] In an embodiment of the present utility model, two sets of exhaust assemblies are provided, and the two sets of exhaust assemblies are symmetrically arranged along the length direction of the mounting base plate 11 to further increase the ventilation effect of the exhaust assembly on the car 2 and improve the experience of residents when taking the elevator.
