Description

Technical Field

[0001] The utility model relates to the technical field of fan dampers, and in particular to a fan damper with a connection structure. Background Art

[0002] A fan damper is a device used to regulate and control the flow of air, typically in ventilation and air conditioning systems. They are used extensively in buildings, industrial and commercial applications to control air flow, temperature, humidity and air quality. A fan damper typically consists of a rotatable panel (also called a damper blade) and a switch mechanism that adjusts the position of the damper, thereby changing the size of the airflow path.

[0003] For example, the Chinese patent with application number 202022253110.2 discloses a damper device for a coal mine ventilator, including a bottom plate, a special-shaped plate and a slide slot, wherein a limit ring 1 and a limit ring 2 are arranged inside the slide slot, the surface of the limit ring 1 is threadedly connected with a screw ring, the side of the limit ring 1 is fixedly connected with a fixed block, and the side of the fixed block is threadedly connected with a threaded rod. When using the damper device for a coal mine ventilator, the main body of the ventilator is placed on the upper surface of the special-shaped plate, the limit ring 1 and the limit ring 2 are stuck on the surface of the main body of the ventilator, and are fixed by the screw ring thread connection, and are further fixed by the connecting rod in the form of extrusion, which is convenient for later installation and disassembly, and easy for maintenance. The handle is turned to drive the threaded rod to rotate, so that one end of the threaded rod supports the main body of the ventilator, which can maintain the stability of the equipment when in use. However, in the specific use process of the device, the size of the wind force cannot be adjusted according to the demand, and the damper of the device cannot be quickly disassembled and installed, which is very troublesome when the internal part of the air outlet needs to be disassembled and repaired. Utility Model Content

[0004] In view of the above problems, the utility model proposes a fan damper with a connection structure to solve the problems existing in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A fan damper with a connection structure comprises a fan body and a connection mechanism, wherein the connection mechanism comprises a damper assembly, one side of the damper assembly is fixedly connected to a connection plate, and the other end of the connection plate away from the damper assembly is fixedly connected to a fan base;

[0007] The damper assembly includes a damper frame, vertical slots are provided on both sides of the damper frame, a servo motor is provided inside the vertical slot, the output shaft of the servo motor is fixedly connected to a screw rod through a coupling, the external thread of the screw rod is connected to a first L-shaped slider, an end of the first L-shaped slider away from the screw rod is plugged with a damper plate, a notch is provided on the other side of the damper plate, a return spring is fixedly connected inside the notch, the other end of the return spring is fixedly connected to a second L-shaped slider, and the second L-shaped slider is movably connected to a guide rod inside.

[0008] A further improvement of the technical solution of the utility model is that an air inlet is fixedly connected to the side of the fan body, a drive motor is fixedly connected to the other side of the fan body, and an air outlet is fixedly connected to the front side of the fan body.

[0009] The above technical solution is adopted, in which a filter is arranged outside the air inlet to filter out some particulate debris in the air while letting in air, thereby protecting the fan body.

[0010] A further improvement of the technical solution of the utility model is that: a support pad is fixedly connected to the bottom of the connecting mechanism, and an anti-slip sticker is pasted on the bottom of the support pad.

[0011] By adopting the above technical solution, the support pad in the solution can keep the fan body at a certain distance from the ground, preventing the fan body from getting damp due to long-term contact with the ground, and the anti-slip pad can improve the stability of the device.

[0012] A further improvement of the technical solution of the utility model is that: two groups of vertical slots are provided, symmetrically distributed on both sides of the damper frame, and the guide rod is fixedly connected to the inside of the vertical slot on the right side and is on the same horizontal plane as the screw rod and remains parallel.

[0013] By adopting the above technical solution, the setting of the guide rod in the solution can enable the first L-shaped slider and the second L-shaped slider to jointly drive the damper plate to move up and down, thereby improving the stability during the translation process.

[0014] A further improvement of the technical solution of the utility model is that rubber pads are arranged around the inner wall of the damper plate, and the rubber pads are fitted with the front side of the damper frame.

[0015] By adopting the above technical solution, the rubber pad arranged on the inner wall of the damper plate in the solution can well increase the sealing performance of the damper plate, thereby achieving a better effect of air volume regulation.

[0016] A further improvement of the technical solution of the utility model is that: two groups of return springs are provided, both of which are tightly fitted with the side surface of the second L-shaped sliding block, and when the damper plate is installed, the return springs are in a semi-compressed state.

[0017] By adopting the above technical solution, two groups of reset springs are provided in the solution to share the pressure together, thereby increasing the service life of the springs. When the first L-shaped slider is plugged into the interior of the damper plate, the spring is reset and the plug-in effect becomes more stable.

[0018] A further improvement of the technical solution of the utility model is that an opening having a size consistent with the air outlet is provided in the middle of the air door frame, and the length and width of the air door plate are both larger than the air outlet.

[0019] The above-mentioned technical scheme is adopted. The outer diameter size of the damper frame in this scheme is set so that when the fan is stopped, the first L-shaped slider moves down to the lowest point, so that the damper is in a closed state as a whole, preventing dust and other debris from entering the inside of the fan body when the fan stops working, so as to avoid damaging the fan body, thereby protecting the fan body to a certain extent.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a fan damper with a connection structure, which adopts the cooperation of a servo motor, a screw rod, a first L-shaped slider, a damper plate, and a guide rod.

[0031] The damper assembly 401 includes a damper frame 4011, vertical slots 4012 are provided on both sides of the damper frame 4011, a servo motor 4013 is provided inside the vertical slot 4012, the output shaft of the servo motor 4013 is fixedly connected to a screw rod 4014 through a coupling, the external thread of the screw rod 4014 is connected to a first L-shaped slider 4015, the end of the first L-shaped slider 4015 away from the screw rod 4014 is plugged with a damper plate 4016, a slot 4017 is provided on the other side of the damper plate 4016, a return spring 4018 is fixedly connected inside the slot 4017, the other end of the return spring 4018 is fixedly connected to a second L-shaped slider 4019, and the second L-shaped slider 4019 is movably connected to a guide rod 4020 inside.

[0032] In this embodiment, a servo motor 4013, a screw rod 4014, a first L-shaped slider 4015, a damper plate 4016, and a guide rod 4020 are coordinated. The servo motor 4013 drives the screw rod 4014 to rotate, so that the first L-shaped slider 4015 drives the damper plate 4016 to move up and down, thereby controlling the air volume. This solves the problem that the air volume at the air outlet 6 cannot be adjusted, thereby improving the applicability of the device.

[0033] Example 2

[0034] like Figure 1-4As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, an air inlet 2 is fixedly connected to the side of the fan body 1, a drive motor 3 is fixedly connected to the other side of the fan body 1, an air outlet 6 is fixedly connected to the front side of the fan body 1, a support pad 5 is fixedly connected to the bottom of the connecting mechanism 4, an anti-slip sticker is pasted on the bottom of the support pad 5, two groups of vertical grooves 4012 are provided, which are symmetrically distributed on both sides of the damper frame 4011, and the guide rod 4020 is fixedly connected to the inside of the vertical groove 4012 on the right side and is on the same horizontal plane as the position of the screw rod 4014 and remains parallel.

[0035] In this embodiment, a filter is provided on the outside of the air inlet 2 in the scheme, which filters some particulate matter in the air while taking in air, thereby protecting the fan body 1.

[0036] Example 3

[0037] like Figure 1-4 As shown, on the basis of Example 1 and Example 2, the utility model provides a technical solution: preferably, rubber pads are arranged around the inner wall of the damper plate 4016, and the rubber pads are fitted with the front of the damper frame 4011, two groups of return springs 4018 are arranged, both of which are tightly fitted with the side of the second L-shaped slider 4019, and when the damper plate 4016 is installed, the return spring 4018 is in a semi-compressed state, and an opening consistent with the size of the air outlet 6 is opened in the middle of the damper frame 4011, and the length and width of the damper plate 4016 are both larger than the air outlet 6.

When the first L-shaped slider 4015 is plugged into the damper plate 4016, the spring is reset and the plug-in effect becomes more stable. The outer diameter size of the damper frame 4011 in the scheme is set so that when the fan is stopped, the first L-shaped slider 4015 moves down to the lowest point, so that the damper is in a closed state as a whole, thereby preventing dust and other debris from entering the inside of the fan body 1 when the fan stops working, so as to avoid damaging the fan body 1, thereby protecting the fan body 1 to a certain extent.

[0039] The working principle of the fan damper with a connection structure is described in detail below.

[0040] like Figure 1-4 As shown, when in use, the fan body 1 is placed on the fan base 402, and the air outlet 6 is aligned with the air door frame 4011. When the wind force needs to be adjusted, the servo motor 4013 is started, and the servo motor 4013 drives the screw rod 4014 to rotate. At this time, the first L-shaped slider 4015 connected to the external thread of the screw rod 4014 and the second L-shaped slider 4019 connected to the external active connection of the guide rod 4020 jointly drive the air door plate 4016 to move up and down to adjust the size of the air outlet.
