Abstract
Description
Technical Field
[0001] This utility model belongs to the field of jet fan technology, and in particular relates to an energy-saving jet fan. Background Technology
[0002] A jet fan is a ventilation device that relies on a motor to drive an impeller to rotate at high speed, causing air to form a high-speed jet. When working, the high-speed jet generated inside the fan drives a large amount of surrounding air to flow together due to the entrainment effect, thereby achieving ventilation. Compared with ordinary fans, its advantage is that it can efficiently disturb the airflow in a large space without relying on a duct system, and it is widely applicable to various ventilation needs.
[0003] However, in actual operation, traditional jet fans face the severe challenge of complex and ever-changing ventilation demands. The required ventilation volume varies greatly depending on the time of day and the scenario. Traditional jet fans are not convenient for flexibly adjusting the air intake volume according to ventilation demands. As a result, when the ventilation demand is low, if the fan still maintains a large air volume, it will cause a lot of energy waste and increase operating costs. During periods of high demand, if the air volume cannot be increased in time, not only will the ventilation effect be poor, but the fan may also consume additional energy due to frequent start-stop operation, which will exacerbate energy loss. Utility Model Content
[0004] The purpose of this utility model is to provide an energy-saving jet fan. By incorporating an adjustment mechanism, specifically when the air intake of the fan body needs adjustment, a motor on the top wall of the drive box is activated. The motor drives the rotating shaft to rotate, and through connecting block one, connecting plate one, connecting block two, and connecting plate two, the rotating shafts rotate synchronously, thereby driving the adjustment plate to rotate. This rotation of the adjustment plate changes the air intake area of the air inlet pipe. When ventilation demand is low, the air intake is reduced, lowering the fan body's energy consumption and achieving energy saving; when demand is high, the air intake is increased. This allows for flexible adjustment of the air volume according to actual needs, effectively saving energy and improving the fan's efficiency. It solves the problem that traditional jet fans are not convenient for flexibly adjusting the air intake volume according to ventilation needs.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to an energy-saving jet fan, comprising a fan body, on which an adjustment mechanism and a disassembly mechanism are provided.
[0007] The adjustment mechanism includes an air outlet pipe fixedly connected to the left side of the fan body, an air inlet pipe fixedly connected to the right side of the fan body, an adjustment box fixedly connected to the right end of the air inlet pipe, a drive box fixedly connected to the top of the adjustment box, a plurality of rotating shafts rotatably connected to the inner bottom wall of the adjustment box, the top ends of the plurality of rotating shafts extending into the interior of the drive box and rotatably connected to the drive box, and adjustment plates fixedly connected to the outer walls of the plurality of rotating shafts. The disassembly mechanism includes two mounting seats fixedly connected to the front and rear sides of the adjustment box.
[0008] Furthermore, a motor is fixedly connected to the inner top wall of the drive box, and the output shaft of the motor is fixedly connected to the corresponding rotating shaft through a coupling. A connecting block is fixedly connected to the outer wall of each of the rotating shafts.
[0009] Furthermore, a guide rod is fixedly connected to the inner wall of the drive box, a slider is slidably connected to the outer wall of the guide rod, and a connecting plate is fixedly connected to the side of the slider away from the guide rod.
[0010] Furthermore, a plurality of connecting blocks 2 are fixedly connected to the side of the connecting plate 2 away from the slider, and each of the plurality of connecting blocks 2 is fixedly connected to a corresponding connecting block 1 by a connecting plate 1.
[0011] Furthermore, a filter plate is slidably connected to the right side of the regulating box, and positioning grooves are provided on the right side of both mounting seats. Positioning plates are fixedly connected to the front and rear sides of the filter plate, and the left sides of both positioning plates extend into the interior of the corresponding positioning grooves and are slidably connected to the corresponding positioning grooves.
[0012] Furthermore, each of the two mounting bases has a sliding groove on its top, and a positioning pin is slidably connected to the inner wall of each of the two sliding grooves. One end of each of the two positioning pins extends to the outside of the corresponding mounting base, and the other end of each of the two positioning pins passes through the corresponding positioning plate and is slidably connected to the corresponding positioning plate.
[0013] Furthermore, each of the two positioning pins has a connecting piece fixedly connected to its outer wall, and a spring is wound around the outer wall of each of the two positioning pins. One end of each of the two springs is fixedly connected to the corresponding connecting piece, and the other end of each of the two springs is fixedly connected to the inner wall of the corresponding slide groove.
[0014] Furthermore, each of the two positioning pins is fixedly connected to a fixing plate at its top end, and each of the two fixing plates is threadedly connected to its corresponding mounting base with two bolts.
[0015] This utility model has the following beneficial effects:
[0016] 1. By setting up an adjustment mechanism, specifically when it is necessary to adjust the air intake of the fan body, the motor on the top wall of the drive box is started. The motor drives the rotating shaft to rotate, and through connecting block one, connecting plate one, connecting block two, and connecting plate two, the rotating shafts rotate synchronously, which in turn drives the adjustment plate to rotate. Thus, by rotating the adjustment plate, the air intake area of the air intake pipe is changed. When the ventilation demand is low, the air intake is reduced, reducing the energy consumption of the fan body and achieving energy saving; when the demand is high, the air intake is increased. The air volume is flexibly adjusted according to the actual needs, effectively saving energy and improving the efficiency of the fan.
[0017] 2. By setting up a disassembly mechanism, specifically, when disassembling the filter plate, first remove the bolts between the fixing plate and the mounting base. At this time, the fixing plate is no longer constrained, and the positioning pin, under the elastic force of the spring, moves upward through the connecting piece, causing it to disengage from the positioning plate. Then, the filter plate can be easily slid out from the right side of the adjustment box. During installation, align the positioning plate of the filter plate with the positioning groove of the mounting base and slide it in to achieve initial positioning. Press the fixing plate so that the positioning pin passes through the positioning plate, and then fix the fixing plate with bolts to complete the installation. This makes it easy to install and disassemble the filter plate, thoroughly clean and maintain the filter plate, ensure the cleanliness of the air entering the fan body, and extend the service life of the fan.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7As shown, this utility model is an energy-saving jet fan, including a fan body 1. The fan body 1 is equipped with an adjustment mechanism 2 and a disassembly mechanism 3. The adjustment mechanism 2 includes an air outlet pipe 21 fixedly connected to the left side of the fan body 1, an air inlet pipe 22 fixedly connected to the right side of the fan body 1, an adjustment box 23 fixedly connected to the right end of the air inlet pipe 22, a drive box 24 fixedly connected to the top of the adjustment box 23, and several rotating shafts 25 rotatably connected to the inner bottom wall of the adjustment box 23. The top ends of the rotating shafts 25 extend into the interior of the drive box 24 and are rotatably connected to the drive box 24. Adjustment plates 26 are fixedly connected to the outer walls of the rotating shafts 25. The disassembly mechanism 3 includes two mounting seats 31 fixedly connected to the front and rear sides of the adjustment box 23. A motor 27 is fixedly connected to the inner top wall of the drive box 24. The output shaft of the motor 27 is fixedly connected to the corresponding rotating shaft 25 via a coupling. Connecting blocks 28 are fixedly connected to the outer walls of the rotating shafts 25. A guide plate 28 is fixedly connected to the inner wall of the drive box 24. A guide rod 213 is slidably connected to a slider 212 on its outer wall. A connecting plate 211 is fixedly connected to the side of the slider 212 away from the guide rod 213. Several connecting blocks 29 are fixedly connected to the side of the connecting plate 211 away from the slider 212. Each of the connecting blocks 29 is fixedly connected to a connecting plate 210 between itself and its corresponding connecting block 28. By setting an adjustment mechanism 2, when it is necessary to adjust the air intake of the fan body 1, the motor 27 on the top wall of the drive box 24 is started. The motor 27 drives the rotating shaft 25 to rotate. Through the connecting block 28, connecting plate 210, connecting block 29, and connecting plate 211, the rotating shaft 25 rotates synchronously, thereby driving the adjustment plate 26 to rotate. Thus, by rotating the adjustment plate 26, the air intake area of the air intake pipe 22 is changed. When the ventilation demand is low, the air intake is reduced to reduce the energy consumption of the fan body 1 and achieve energy saving. When the demand is high, the air intake is increased. The air volume is flexibly adjusted according to the actual demand, effectively saving energy and improving the efficiency of the fan.
[0031] A filter plate 32 is slidably connected to the right side of the regulating box 23. Positioning grooves 33 are provided on the right sides of both mounting bases 31. Positioning plates 34 are fixedly connected to the front and rear sides of the filter plate 32. The left sides of both positioning plates 34 extend into the interior of the corresponding positioning grooves 33 and are slidably connected to them. Slide grooves 35 are provided on the top of both mounting bases 31. Positioning pins 36 are slidably connected to the inner walls of both slide grooves 35. One end of each positioning pin 36 extends to the outside of the corresponding mounting base 31, and the other end of each positioning pin 36 passes through the corresponding positioning plate 34 and is slidably connected to it. Connecting pieces 37 are fixedly connected to the outer walls of both positioning pins 36. Springs 38 are wound around the outer walls of both positioning pins 36. One end of each spring 38 is fixedly connected to the corresponding connecting piece 37, and the other end of each spring 38 is fixedly connected to the inner wall of the corresponding slide groove 35. Each filter plate 32 is fixedly connected to a fixing plate 39 at its top. Each fixing plate 39 is threadedly connected to a corresponding mounting base 31 by two bolts 310. By setting a disassembly mechanism 3, specifically when disassembling the filter plate 32, the bolts 310 between the fixing plate 39 and the mounting base 31 are first removed. At this time, the fixing plate 39 is unrestrained, and the positioning pin 36, under the elastic force of the spring 38, moves upward through the connecting piece 37, causing it to disengage from the positioning plate 34. Then, the filter plate 32 can be easily slid out from the right side of the regulating box 23. During installation, the positioning plate 34 of the filter plate 32 is aligned with the positioning groove 33 of the mounting base 31 and slid in to achieve initial positioning. The fixing plate 39 is pressed so that the positioning pin 36 passes through the positioning plate 34. The fixing plate 39 is then fixed with bolts 310 to complete the installation. This makes the filter plate 32 easy to install and disassemble, and allows for thorough cleaning and maintenance of the filter plate 32, ensuring the cleanliness of the air entering the fan body 1 and extending the service life of the fan.
[0032] A specific application of this embodiment is as follows: When using the device, the motor 27 installed on the top wall inside the drive box 24 is started. The output shaft of the motor 27 drives the connected rotating shaft 25 to start rotating. When the motor 27 drives the corresponding rotating shaft 25 to rotate, the connecting block 28 on the rotating shaft 25 will drive the corresponding connecting block 29 to move through the corresponding connecting plate 210. This causes the connecting plate 211 to slide on the guide rod 213 through the slider 212. The slider 212 and the guide rod 213 guide and limit the movement path of the connecting plate 211, thereby keeping the movement of the connecting plate 211 stable. Since several connecting blocks are fixed on the connecting plate 211... Connecting block 29, each of which is fixedly connected to the corresponding connecting block 28 by a connecting plate 210. Therefore, when the connecting plate 211 moves, the other rotating shafts 25 will rotate synchronously. When the rotating shaft 25 rotates, the adjusting plate 26 fixed on its outer wall will rotate with the rotating shaft 25. Since the adjusting box 23 is connected to the air inlet pipe 22, the change in the rotation angle of the adjusting plate 26 will change the air inlet area of the air inlet pipe 22. When the ventilation demand is low, the adjusting plate 26 rotates to reduce the air inlet area, reduce the air volume entering the fan body 1, reduce the fan energy consumption, and achieve energy saving. When the ventilation demand increases, the adjusting plate 26 rotates in the opposite direction through the rotating shaft 25 to increase the air inlet area.
[0033] The filter plate 32 is installed on the right side of the regulating box 23 to filter the air entering the fan, blocking dust, debris, etc., ensuring the cleanliness of the air entering the fan body 1, and extending the service life of the fan. When installing the filter plate 32, the filter plate 32 is placed on the right side of the regulating box 23, and the positioning plate 34 on the filter plate 32 will slide into the corresponding positioning groove 33. This step serves as the initial positioning of the filter plate 32. After the positioning plate 34 slides into the positioning groove 33, the fixing plate 39 is pressed, causing the fixing plate 39 to drive the lower end of the positioning pin 36 to move downward and pass through the positioning plate 34, thereby locking the positioning plate 34 in the positioning groove 33, so that the filter plate 32 is stably installed on the regulating box 23. Meanwhile, when the positioning pin 36 moves, it will drive the spring 38 to stretch through the connecting piece 37, and finally fix the fixing plate 39 to the mounting base 31 through the bolt 310, so that the positioning pin 36 cannot move, thereby further ensuring the stability of the filter plate 32 installation. When the filter plate 32 needs to be disassembled, first loosen the bolt 310 and remove the bolt 310. At this time, the fixing plate 39 is no longer fixed, and the spring 38 returns to its original position and contracts under its own elasticity, thereby driving the positioning pin 36 to move through the connecting piece 37, so that the lower end of the positioning pin 36 is disengaged from the positioning plate 34. At this time, the filter plate 32 can be slid out from the right side of the adjustment box 23 to complete the disassembly operation.
