Technical Field

[0001] The invention relates to the technical field of fans, in particular to a low-noise cooling fan with adjustable air supply direction. Background Art

[0002] ‌Low-noise air cooler is a ventilation device that adopts advanced aerodynamic design and optimized fan blade structure. It is designed to provide low noise, high efficiency and stable cooling effect. By optimizing the fan blade structure and adopting advanced aerodynamic design, the noise generated by the rotation of the fan blade is effectively reduced. It has a large air volume and a wide air supply range, which can meet the ventilation needs of different places. This kind of equipment is usually used in environments that require cooling and ventilation, such as factory workshops, shopping malls, offices, etc. It can minimize the impact of noise on the environment and human body while ensuring good ventilation effect.

[0003] When the existing low-noise air cooler is in use, it can only supply air in a directional manner because it does not have the function of adjusting the air supply direction, which makes the air supply effect of the fan unsatisfactory and leads to reduced ventilation and cooling. Summary of the invention

The driving tooth and the multiple adjusting tooth sleeves on the same side are provided with an adjustment chain. When the driving motor drives the impeller to rotate, the air inlet can inhale the external airflow through the sleeve, which is convenient for the filter to filter the external airflow and then discharge it through the air outlet. When the air supply direction needs to be adjusted, the double-axis brake reduction motor can be started to drive the driving shaft to drive the driving teeth to rotate, so that under the transmission of the driving teeth, adjusting teeth and the sprocket teeth of the adjustment chain, the rotating shaft can drive the blade to adjust the angle, thereby realizing the adjustment of the air supply direction.

[0006] As a preferred technical solution, an air outlet utilization component and an air outlet reinforcement component are provided on the shell, and the operation of the driving motor is utilized to provide operating driving force for the air outlet utilization component and the air outlet reinforcement component.

[0007] As a preferred technical solution, the air outlet utilization assembly includes a driving wheel, a fixed plate, a rotating column, a driven wheel, a transmission belt, a reciprocating screw, a transmission tooth, a fixed ring rail, a rotating ring, a driven tooth, a transmission chain, a linkage rod and a dust removal plate;

[0008] A driving wheel is installed on the output shaft of the driving motor, and two fixed plates are symmetrically installed on the shell, and rotating columns are rotatably installed on the two fixed plates. A driven wheel is installed on the end of the rotating column close to the driving wheel, and a transmission belt is sleeved on the driving wheel and the driven wheel. The two rotating columns are connected by a reciprocating screw, and a transmission tooth is installed on the end of the rotating column away from the driven wheel. A fixed ring rail is installed on the side of the shell close to the air inlet, and a swivel is rotatably installed on the fixed ring rail. A driven tooth is installed on the swivel, and a transmission chain is sleeved on the transmission tooth and the driven tooth, and two linkage rods are symmetrically installed on the swivel. The two linkage rods are connected by a transmission chain. The dust plate is connected, and the dust removal plate is in contact with the filter screen. When the driving motor is running, the driving motor can drive the driving wheel to rotate. During the rotation, the driving wheel can drive the driven wheel to rotate through the transmission belt, so that the driven wheel can drive the transmission teeth to rotate synchronously through the rotating column and the reciprocating screw. Since the swivel can rotate on the fixed ring rail, the transmission teeth can drive the driven teeth to rotate through the transmission chain during the rotation. The rotation of the driven teeth can realize the periodic rotation of the swivel, which is beneficial for the swivel to drive the dust removal plate to rotate through the linkage rod during the rotation, so that the dust removal plate can perform comprehensive dust removal treatment on the filter screen during the rotation.

[0009] As a preferred technical solution, the length of the dust removal plate is the same as the diameter of the filter screen.

[0010] As a preferred technical solution, the air outlet reinforcement assembly includes a slide seat, a cross bar, an extrusion plate, a driving airbag, a connecting rod, a fixed arc plate, a pressurized airbag and a clamping plate;

[0011] A sliding seat is slidably installed on the reciprocating screw, and the two fixed plates are connected by a cross bar. An extrusion plate is slidably installed on the cross bar, and the extrusion plate is connected to the fixed plate by a driving airbag, and the extrusion plate is connected to the sliding seat by a connecting rod. Two fixed arc plates are symmetrically installed on one side of the shell near the air inlet, and telescopic rods are installed on the opposite surfaces of the two fixed arc plates. A clamping plate is installed on the telescopic rod, and the clamping plate is connected to the fixed arc plate by a pressurized airbag, and an elastic band is connected to the clamping plate and the fixed arc plate. The input end of the pressurized airbag is connected to the output end of the driving airbag through a one-way air pipe. When the reciprocating screw is moved When rotating, the slide can be driven to move back and forth laterally along the reciprocating screw, and the slide can drive the extrusion plate to move synchronously, so that the extrusion plate can periodically squeeze the driving airbag. When the driving airbag is squeezed, the airflow in the driving airbag can enter the boosting airbag through the one-way air pipe, and the volume expansion of the boosting airbag can push the clamping plate to move. The sleeve can be clamped and fixed by the relative movement of the two clamping plates, thereby ensuring the stability of the sleeve during the airflow conveying process and achieving the effect of noise reduction. When the driving airbag is stretched as the extrusion plate is reset, the driving airbag can inhale external airflow for recovery.

When the air intake needs to be increased, the power of the driving motor is increased, so that the driven wheel can realize the self-rotation of the fixed column during the rotation process, and the centrifugal force on the squeezing ball can be greater than the elastic force of the supporting spring, so that the squeezing ball can push the slide to compress the supporting spring, so that the slide can drive the pressing plate to squeeze the touch switch through the connecting rod, so that the touch switch can be self-started according to the power change of the driving motor.

[0015] As a preferred technical solution, the touch switch is electrically connected to the pressure-stabilizing valve and the air release valve. In the initial state, the air release valve is open and the pressure-stabilizing valve is closed. When the touch switch is touched, the air release valve can be controlled to close and the pressure-stabilizing valve to open, which is beneficial for the pressurized airbag to expand to its maximum volume, allowing the pressurized airbag to discharge airflow through the pressure-stabilizing valve, thereby achieving stable support of the clamping plate by the pressurized airbag, and when the touch switch is disconnected, the airflow in the pressurized airbag can be discharged through the air release valve, making it convenient for the clamping plate to be reset under the action of the elastic band.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the air supply direction needs to be adjusted, the dual-axis brake reduction motor can be started to allow the driving shaft to drive the driving teeth to rotate, so that under the transmission of the driving teeth, adjusting teeth and the sprocket teeth of the adjustment chain, the rotating shaft can drive the blades to adjust the angle, thereby achieving the adjustment of the air supply direction.

[0018] The present application sets up an air outlet utilization component and utilizes the operation of a driving motor. Under the pulley transmission composed of a driving wheel, a transmission belt and a driven wheel, and the sprocket transmission of a transmission tooth, a transmission chain and a driven tooth, the periodic rotation of the rotating ring can be achieved, thereby facilitating the dust removal plate to carry out comprehensive dust removal treatment on the filter screen.

[0037] The length of the dust removal plate 1613 is the same as the diameter of the filter screen 7 .

[0038] like Figure 1-Figure 4 and Figure 6-Figure 9 As shown, the air outlet reinforcement assembly 17 includes a slide seat 1701, a cross bar 1702, an extrusion plate 1703, a driving airbag 1704, a connecting rod 1705, a fixed arc plate 1706, a pressurized airbag 1707 and a clamping plate 1708;

[0039] A slide seat 1701 is slidably mounted on the reciprocating screw 1606, the two fixed plates 1602 are connected by a cross bar 1702, an extrusion plate 1703 is slidably mounted on the cross bar 1702, the extrusion plate 1703 is connected to the fixed plate 1602 by a driving airbag 1704, and the extrusion plate 1703 is connected to the slide seat 1701 by a connecting rod 1705, two fixed arc plates 1706 are symmetrically mounted on one side of the shell 1 close to the air inlet 4, telescopic rods are mounted on the opposite surfaces of the two fixed arc plates 1706, a clamping plate 1708 is mounted on the telescopic rod, the clamping plate 1708 is connected to the fixed arc plate 1706 by a pressurized airbag 1707, and the clamping plate 1708 is connected to the fixed arc plate 1706 by an elastic belt 1709, the input end of the pressurized airbag 1707 and the output end of the driving airbag 1704 are connected by a single When the reciprocating screw 1606 rotates, the slide 1701 can be driven to move back and forth laterally along the reciprocating screw 1606, so that the slide 1701 can drive the extrusion plate 1703 to move synchronously, so that the extrusion plate 1703 can periodically squeeze the driving airbag 1704. When the driving airbag 1704 is squeezed, the airflow in the driving airbag 1704 can enter the boosting airbag 1707 through the one-way airway. The volume expansion of the boosting airbag 1707 can push the clamping plate 1708 to move.

When the driving airbag 1704 is stretched as the extrusion plate 1703 is reset, the driving airbag 1704 can inhale external airflow for recovery.

[0040] A one-way air intake valve is installed on the input end of the driving airbag 1704, and a pressure stabilizing valve and an air release valve are installed on the output end of the boosting airbag 1707.

[0041] The air outlet reinforcement assembly 17 further includes a fixing column 1710, a cylindrical chamber 1711, a squeezing ball 1712, a touch switch 1713, a slide plate 1714, a supporting spring 1715, a connecting rod 1716 and a pressing plate 1717;

[0044] Working principle of the present invention:

[0045] When the driving motor 3 drives the impeller 2 to rotate, the air inlet 4 can inhale the external airflow through the sleeve 6, which is convenient for the filter net 7 to filter the external airflow and then discharge it through the air outlet 8. When the air supply direction needs to be adjusted, the double-axis brake reduction motor 12 can be started to allow the driving shaft 13 to drive the driving gear 14 to rotate, so that under the sprocket transmission of the driving gear 14, the adjusting gear 11 and the adjusting chain 15, the rotating shaft 9 can drive the blade 10 to adjust the angle, thereby realizing the adjustment of the air supply direction.

[0046] When the driving motor 3 is running, the driving motor 3 can drive the driving wheel 1601 to rotate. During the rotation, the driving wheel 1601 can drive the driven wheel 1604 to rotate through the transmission belt 1605, so that the driven wheel 1604 can drive the transmission tooth 1607 to rotate synchronously through the rotating column 1603 and the reciprocating screw 1606. Since the rotating ring 1609 can rotate on the fixed ring rail 1608, the transmission tooth 1607 can drive the driven tooth 1610 to rotate through the transmission chain 1611 during the rotation. The rotation of the driven tooth 1610 can realize the periodic rotation of the rotating ring 1609, which is beneficial for the rotating ring 1609 to drive the dust removal plate 1613 to rotate through the linkage rod 1612 during the rotation, so that the dust removal plate 1613 can perform comprehensive dust removal treatment on the filter screen 7 during the rotation.

[0047] When the reciprocating screw 1606 rotates, the slide 1701 can be driven to move back and forth laterally along the reciprocating screw 1606, so that the slide 1701 can drive the extrusion plate 1703 to move synchronously, so that the extrusion plate 1703 can periodically squeeze the driving airbag 1704. When the driving airbag 1704 is squeezed, the airflow in the driving airbag 1704 can enter the boosting airbag 1707 through the one-way air pipe. When the driving motor 3 is running at normal power, the airflow entering the boosting airbag 1707 can be directly discharged through the air relief valve. When it is necessary to increase the air intake and the power of the driving motor 3, the driven wheel 1604 can realize the fixing column 1710 during the rotation process. The self-rotation can make the centrifugal force on the squeezing ball 1712 greater than the elastic force of the supporting spring 1715, so that the squeezing ball 1712 can push the slide plate 1714 to compress the supporting spring 1715, so that the slide plate 1714 can drive the pressing plate 1717 to squeeze the touch switch 1713 through the connecting rod 1716, so as to control the closing of the air release valve and the opening of the pressure regulating valve, so that the volume of the boosting airbag 1707 expands under the action of the airflow, and the volume expansion of the boosting airbag 1707 can be used to push the clamping plate 1708 to move, and the two clamping plates 1708 can move towards each other to clamp and fix the sleeve 6, thereby ensuring the stability of the sleeve 6 during the airflow conveying process and achieving the effect of noise reduction.
