Technical Field
[0001] This utility model relates to the field of elevator crossflow fan technology, specifically to an elevator crossflow fan with a speed regulating device. Background Technology
[0002] In the prior art, for example, Chinese utility model patent (authorization announcement number CN212657837U) discloses a crossflow fan device for elevators. Its structure includes an elevator, a bracket welded to the top of the elevator, a filter housing welded to the top of the elevator via the bracket, an air duct inserted into the right side of the filter housing, an air purifier inserted into the right side of the filter housing via the air duct, a fan inserted into the right side of the air purifier via the air duct, and a sterilization device inserted into the right side of the fan via the air duct. This crossflow fan device for elevators blows air much like natural wind, providing a cool and comfortable feel without directly blowing on people. It offers good purification, maximizing comfort, effectively reducing noise and vibration, and charging the battery under normal conditions. It continues to operate normally even in the event of a power outage. The clean air helps calm the anxious hearts of trapped passengers, encouraging them to patiently await rescue.
[0003] When the aforementioned crossflow fan device is working, the first and second filter layers filter the air drawn in and then discharge it after purification. However, when the first and second filter layers filter dust and impurities in the outside air, the filter pores inside are also easily blocked, which leads to inconvenient air circulation and reduces the working efficiency of the crossflow fan. Utility Model Content
[0004] To address the aforementioned issues, an elevator crossflow fan with a speed control device is provided. The motor drives a synchronous pulley to rotate, and the interaction between the synchronous pulley and the synchronous belt drives a rotating rod to rotate. The rotating rod then drives a contact block to rotate, and the contact block reciprocates by pressing the activated carbon filter plate. This causes the activated carbon filter plate to vibrate continuously under the action of a spring telescopic rod, effectively preventing the filter pores inside the activated carbon filter plate from becoming clogged.
[0005] To address the problems of existing technologies, this utility model provides an elevator crossflow fan with a speed regulating device, including a mounting plate installed inside the elevator. A housing is provided on one side of the mounting plate, and a crossflow fan is installed inside the housing. A motor is provided on one side of the housing, and the output shaft of the motor is connected to the crossflow fan. An air outlet duct for air outlet is provided inside the housing. An activated carbon filter plate for filtering dust and impurities is provided on the top of the housing. A vibration component for preventing the activated carbon filter plate from clogging is provided inside the housing.
[0006] Preferably, the vibration assembly includes mounting blocks disposed on the inner walls of both sides of the housing, and each mounting block is provided with a spring telescopic rod on both sides of its top. The telescopic ends of the spring telescopic rods are connected to the bottom of the activated carbon filter plate. A rotating rod is also rotatably disposed on the inner wall of the housing, one end of which extends to the outside of the housing. An abutment block for squeezing the activated carbon filter plate is disposed on the outside of the rotating rod.
[0007] Preferably, the output shaft and the rotor of the motor are both provided with synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt drive.
[0008] Preferably, the interior of the housing is equipped with a collection drawer for collecting dust and impurities.
[0009] Preferably, a positioning frame is provided on one side of the collection drawer, and a pull rod is movably provided on both sides of the positioning frame. A positioning pin is provided at one end of the pull rod, and a return spring is sleeved on the outside of the pull rod. One end of the return spring is connected to the inner wall of the positioning frame, and the other end of the return spring is connected to the side wall of the positioning pin. A positioning hole adapted to the positioning pin is opened on the side wall of the outer shell.
[0010] Preferably, a control panel and a temperature sensor are provided on the other side of the housing, and the control panel is electrically connected to the temperature sensor and the motor respectively via wires.
[0011] The advantages of this utility model compared to the prior art are:
[0012] 1. The motor drives the synchronous pulley to rotate. The synchronous pulley and the synchronous belt work together to drive the rotating rod to rotate. The rotating rod then drives the contact block to rotate. The contact block reciprocates and squeezes the activated carbon filter plate, so that the activated carbon filter plate is constantly vibrating under the action of the spring telescopic rod, which effectively prevents the filter pores inside the activated carbon filter plate from being blocked.
[0013] 2. The temperature inside the elevator is monitored in real time by a temperature sensor. When the temperature inside the elevator changes, a signal is sent to the control panel, which then controls the motor to adjust the speed of the cross-flow fan. Attached Figure Description

[0021] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figures 1 to 6 As shown, this utility model provides:
[0023] An elevator crossflow fan with a speed control device includes a mounting plate 1 installed inside the elevator. A housing 4 is provided on one side of the mounting plate 1. A crossflow fan 12 is provided inside the housing 4. A motor 2 is provided on one side of the housing 4. The output shaft of the motor 2 is connected to the crossflow fan 12. An air outlet duct 3 for air outlet is provided inside the housing 4. An activated carbon filter plate 6 for filtering dust and impurities is provided on the top of the housing 4. A vibration assembly for preventing the activated carbon filter plate 6 from clogging is provided inside the housing 4.
[0024] The motor 2 drives the crossflow fan 12 to work. When the crossflow fan 12 is working, it will draw in the outside air from the top of the housing 4 and blow it out from the air outlet duct 3. While drawing in the air, the crossflow fan 12 will also easily adsorb the outside dust and impurities into the inside of the housing 4. At this time, the activated carbon filter plate 6 on the top of the housing 4 can filter the dust and impurities and remove the odor inside the elevator. At the same time, the vibration component will prevent the filter pores inside the activated carbon filter plate 6 from being blocked.
[0025] like Figure 6As shown, the vibration assembly includes mounting blocks 13 disposed on the inner walls of both sides of the housing 4. Each mounting block 13 is provided with a spring telescopic rod 17 on both sides of its top. The telescopic ends of the spring telescopic rod 17 are connected to the bottom of the activated carbon filter plate 6. A rotating rod 18 is also rotatably disposed on the inner wall of the housing 4. One end of the rotating rod 18 extends to the outside of the housing 4. An abutment block 19 for squeezing the activated carbon filter plate 6 is disposed on the outside of the rotating rod 18.
[0026] The rotating rod 18 drives the contact block 19 to rotate, and the contact block 19 reciprocates to squeeze the activated carbon filter plate 6, so that the activated carbon filter plate 6 is in a state of vibration under the action of the spring telescopic rod 17, which effectively prevents the filter holes inside the activated carbon filter plate 6 from being blocked.
[0027] like Figure 1 and Figure 6 As shown, both the output shaft of the motor 2 and the outside of the rotating rod 18 are provided with synchronous pulleys 10, and the two synchronous pulleys 10 are connected by a synchronous belt 9.
[0028] The motor 2 drives the synchronous pulley 10 to rotate, and the synchronous pulley 10 and the synchronous belt 9 work together to drive the rotating rod 18 to rotate. A single drive source can simultaneously drive the crossflow fan 12 and the vibration component, thus saving energy consumption.
[0029] like Figure 4 As shown, the interior of the outer casing 4 is equipped with a collection drawer 11 for collecting dust and impurities.
[0030] The collection drawer 11 can be used to collect and process the dust and impurities that fall off the surface of the activated carbon adsorption plate, thus avoiding the need for secondary cleaning.
[0031] like Figure 5 As shown, a positioning frame 5 is provided on one side of the collection drawer 11, and a pull rod 14 is movably provided on both sides of the positioning frame 5. A positioning pin 16 is provided at one end of the pull rod 14, and a return spring 15 is sleeved on the outside of the pull rod 14. One end of the return spring 15 is connected to the inner wall of the positioning frame 5, and the other end of the return spring 15 is connected to the side wall of the positioning pin 16. A positioning hole adapted to the positioning pin 16 is opened on the side wall of the outer shell 4.
[0032] By pulling the lever 14 outward, the positioning pin 16 is disengaged from the positioning hole on the side wall of the outer casing 4. At this time, it is convenient to take out the positioning frame 5 and the collection drawer 11. The dust and impurities inside the collection drawer 11 can be cleaned. The positioning pin 16 makes the collection drawer 11 stably inserted into the inside of the outer casing 4, so as to prevent the collection drawer 11 from falling down and injuring passengers when the elevator moves up and down.
[0033] like Figure 2 As shown, a control panel 7 and a temperature sensor 8 are provided on the other side of the housing 4. The control panel 7 is electrically connected to the temperature sensor 8 and the motor 2 respectively via wires.
[0034] Temperature sensor 8 monitors the temperature inside the elevator in real time. When the temperature inside the elevator changes, it sends a signal to control panel 7, which then controls motor 2 to adjust the speed of crossflow fan 12.
[0035] In use, the outer casing 4 and the crossflow fan 12 are first installed inside the elevator using the mounting plate 1. Then, the motor 2 is started to drive the crossflow fan 12. When the crossflow fan 12 is working, it draws in outside air from the top of the outer casing 4 and blows it out from the air outlet duct 3. While drawing in air, the crossflow fan 12 also easily adsorbs external dust and impurities into the interior of the outer casing 4. The activated carbon filter plate 6 on the top of the outer casing 4 can then filter out the dust and impurities and remove odors from inside the elevator. However, after prolonged use, the filter pores inside the activated carbon filter plate 6 are easily clogged, affecting the airflow efficiency. Simultaneously, the motor 2 also drives the synchronous pulley 10 to rotate, utilizing the synchronous pulley... The coordinated operation between 10 and the synchronous belt 9 drives the rotating rod 18 to rotate, which in turn drives the contact block 19 to rotate. The contact block 19 reciprocates by squeezing the activated carbon filter plate 6, causing the activated carbon filter plate 6 to vibrate continuously under the action of the spring telescopic rod 17. This effectively prevents the filter pores inside the activated carbon filter plate 6 from being blocked. At the same time, the collection drawer 11 can be used to collect and process the dust and impurities that fall off the surface of the activated carbon adsorption plate, avoiding the need for secondary cleaning. Then, the temperature sensor 8 monitors the temperature inside the elevator in real time. When the temperature inside the elevator changes, it sends a signal to the control panel 7, which then controls the motor 2 to adjust the wind speed of the crossflow fan 12.
