Description

Technical Field

[0001] The present invention relates to the field of heat dissipation technology, and in particular to a fan structure with multi-faceted air outlets. Background Art

[0002] A fan is an electrical appliance that uses an electric motor to drive rotation to accelerate the circulation of air. The fan is mainly based on the principles of electromagnetism and dynamics. When current passes through the coil of the fan motor, a magnetic field is generated. This magnetic field interacts with the magnetic field in the rotor to cause the rotor to rotate. The blades on the rotor rotate with the rotating magnetic field, thereby driving the surrounding air to rotate together. As the blades rotate, the surrounding air is sucked into the fan, and after acceleration and turning, it is discharged from the fan, thereby achieving the effect of ventilation.

[0003] The existing fan structure usually has only one air outlet and is a single-sided air outlet. A fan with a single-sided air outlet can often only supply air in a fixed direction, which will cause uneven air circulation and fail to effectively distribute the cold air, resulting in higher temperatures in some areas and relatively lower temperatures in other areas. In addition, the fan with a single-sided air outlet has a limited air supply range and poor heat dissipation effect, which is not conducive to personnel use.

[0004] To this end, the present invention provides a fan structure with multi-faceted air outlets. Summary of the invention

[0009] By adopting the above technical solution, the flow of surrounding air can be accelerated, and the heat can be taken away from the surface of the heating element, thereby achieving the purpose of heat dissipation.

[0017] Preferably, an air inlet is provided inside the magnetic block, a duct is installed inside the fan housing close to the magnetic block, and an air outlet end of the duct is located outside the power source of the fan mechanism.

[0018] By adopting the above technical solution, the power source of the fan mechanism can be cooled, thereby extending the service life of the power source.

[0019] Preferably, a wind shield is rotatably installed on one side of the fan cover close to the fan shell, and corresponding openings are provided inside the wind shield close to the air outlet. A screw is installed on the wind shield passing through the inside of the fan cover, and a scraper plate is provided on one side of the wind shield close to the fan cover for processing the air outlet.

[0020] By adopting the above-mentioned technical solution, the air outlet on the fan cover can be processed to prevent dust from clogging the inside of the air outlet and affecting the air delivery. When the wind shield rotates, the wind shield will drive the scraper and brush plate to move. As the wind shield rotates, the scraper and brush plate wipes and cleans along the contour of the air outlet. In this process, the scraper and brush plate can effectively remove dust, dirt and other impurities attached to the surface of the air outlet.

[0021] Preferably, the support seat includes a base plate and a support rod, the support rod is rotatably mounted on the top end of the base plate, and the top end of the support rod is connected to the fan housing.

As the threaded rod rotates and rises or falls, the suction cup connected to the bottom end thereof also moves accordingly. When the suction cup is in close contact with a desktop, the ground or other flat surface, a strong suction force can be quickly formed between the suction cup and the contact surface through manual squeezing operation, thereby ensuring the stability of the device in a fixed position.

[0025] The beneficial effects of the present invention are: The fan structure with multi-sided air outlet described in the present invention is used in conjunction with an air outlet, an exhaust port, a noise reduction ring and a docking port. The noise reduction ring can effectively absorb sound waves, reduce the reflection and propagation of sound, and thus achieve the effect of noise reduction. When the docking port inside the noise reduction ring is aligned with the exhaust port, the wind generated by the fan mechanism can be discharged simultaneously through the air outlet inside the fan cover and the exhaust port and the inside of the docking port, thereby achieving the effect of multi-directional air outlet, expanding its air supply range, and enabling it to better achieve the purpose of heat dissipation, which is further beneficial to personnel use.

[0026] A fan structure with multi-sided air outlets described in the present invention is used in conjunction with a transmission disk and a noise reduction ring. The transmission disk is rotated to transmit information to a transmission groove on the inner wall of the noise reduction ring. When the noise reduction ring rotates to align the internal docking interface with the exhaust port, the wind generated by the fan mechanism can be discharged through the docking interface and the inside of the exhaust port. When the docking interface and the exhaust port are staggered, the wind discharged by the fan mechanism cannot be discharged. At the same time, the exhaust port at some positions is blocked by the noise reduction ring, so that the wind can be discharged through the docking interface at the designated position and the inside of the exhaust port. Therefore, the positions of the exhaust port and the docking interface can be adjusted, so that the wind generated by the fan mechanism is discharged through the designated exhaust port, which is convenient for personnel to operate and use.

[0027] A fan structure with multi-sided air outlet described in the present invention is used in combination with a magnetic block, a magnetic column, an air duct and a duct. When the noise reduction ring rotates, the magnetic block will rotate along with it. When the magnetic block contacts the magnetic column, a repulsive force will be generated therebetween. At this time, the magnetic column will be lifted up, thereby providing a prompt for whether the air outlet and the docking interface are aligned. At the same time, when the magnetic column is lifted up, the air inlet end of the duct will be exposed. At this time, the air duct is connected to the internal guide path of the duct. When the fan mechanism is working, part of the wind generated will be transported to the duct through the inside of the air duct. When the wind is discharged from the air outlet end of the duct, the outside of the motor can be cooled, thereby extending its service life.

[0028] The fan structure with multi-sided air outlet described in the present invention is used in combination with a fixed seat, a spring, a positioning pin, a transmission disc and a positioning hole. When the transmission disc rotates forward, the transmission disc will squeeze the positioning pin, and the positioning pin will squeeze the spring. The spring is compressed inside the fixed seat. When the transmission disc stops rotating, the positioning pin will move inside the fixed seat under the action of the spring. When one end of the positioning pin is located inside the positioning hole, the transmission disc can be positioned, so that the use position of the noise reduction ring and the internal docking interface can be fixed.

[0029] The fan structure with multi-sided air outlet described in the present invention is used in conjunction with a magnetic block and a magnetic column. When the noise reduction ring rotates, the magnetic block will rotate along with it. When the magnetic block contacts the magnetic column, a repulsive force will be generated between them. At this time, the magnetic column will be lifted up, thereby providing a prompt to the exhaust port and the docking port to facilitate timely adjustment by the worker.

[0030] The fan structure with multi-sided air outlet described in the present invention is used in combination with a screw, a wind shield, a passage and a scraper and brush plate. The worker drives the wind shield to rotate by rotating the screw. When the passage inside the wind shield is aligned with the air outlet, the wind generated by the fan mechanism can be discharged through the air outlet. When the passage inside the wind shield is staggered with the air outlet, the wind shield will shield the air outlet. At this time, the wind generated by the fan mechanism cannot be discharged from the air outlet inside the fan cover, so that the surface from which the fan mechanism discharges air can be adjusted. At the same time, when the wind shield rotates, the wind shield will drive the scraper and brush plate to move. The scraper and brush plate can effectively remove dust, dirt and other impurities attached to the surface of the air outlet, thereby ensuring that the inside of the air outlet is always kept clean and unobstructed, thereby avoiding dust clogging the inside of the air outlet and affecting the flow and transportation of wind.

[0033] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples. Example

[0034] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 7 , this application provides a fan structure with multi-sided air outlet, please refer to Figure 1 , Figure 2 and Figure 3 , comprising a support base 1; a fan case 3 is installed on the top of the support base 1, a fan cover 301 is installed on the front of the fan case 3, an air outlet 302 is arranged inside the fan cover 301, a fan mechanism 4 is installed on the front of the inside of the fan case 3, the fan case 3 and the fan cover 301 are used to protect the internal fan mechanism 4, the air outlet 302 is used to discharge the wind generated by the fan mechanism 4, and an air outlet mechanism 5 is rotatably installed on the inner wall of the fan case 3, and the air outlet mechanism 5 is used to discharge the wind generated by the fan mechanism 4 in multiple directions; The air outlet mechanism 5 includes an exhaust port 501, a noise reduction ring 502 and a docking port 503. The noise reduction ring 502 is rotatably installed inside the support seat 1, and the docking port 503 is provided inside the noise reduction ring 502. The exhaust port 501 is provided inside the fan housing 3 near the docking port 503. The noise reduction ring 502 is a plate made of polyester fiber. The porous structure of the polyester fiber enables it to effectively absorb sound waves, reduce the reflection and propagation of sound, and thus achieve the effect of noise reduction.

[0035] Specifically, the fan casing 3 on the top can be supported by the support base 1, and the internal fan mechanism 4 can be protected by the fan casing 3 and the fan cover 301. The operation of the fan mechanism 4 can accelerate the flow of surrounding air to achieve the effect of heat dissipation. The air outlet mechanism 5 can discharge the wind generated by the fan mechanism 4 in multiple directions. When the docking interface 503 inside the noise reduction ring 502 is aligned with the exhaust port 501, the wind generated by the fan mechanism 4 can be discharged through the air outlet 302 inside the fan cover 301 and the exhaust port 501 and the docking interface 503 at the same time. Thereby, the effect of multi-directional air outlet can be achieved, so that the heat dissipation purpose can be better achieved.

[0036] Please refer to Figure 2 and Figure 3The fan mechanism 4 includes a motor 401 and fan blades 402. The motor 401 is installed on the front of the inner wall of the fan housing 3, and the fan blades 402 are installed on the outer side of the output end of the motor 401. Five groups of fan blades 402 are distributed on the outer side of the output end of the motor 401 at equal distances in a circle.

[0037] Specifically, in order to achieve the purpose of heat dissipation, when the motor 401 receives a working instruction and starts to run, the fan blades 402 tightly connected to its output end will rotate accordingly. The rotation of the fan blades 402 is not just a simple mechanical action, it is actually performing a vital physical process - accelerating the flow of surrounding air. During the rotation of the fan blades 402, the surrounding air is precisely cut. This cutting not only changes the original static state of the air, but also effectively promotes the air to flow forward through the shape of the fan blades 402, forming a continuous and stable airflow. During the flow, this airflow will exchange heat with the surface of the heating element, take away the heat from the surface of the element, and gradually dissipate the heat into the surrounding air through the circulation of air. Therefore, when the motor 401 drives the fan blades 402 to rotate, the entire heat dissipation device enters an efficient working state, and the purpose of heat dissipation can be achieved by continuously accelerating the air flow and taking away the heat from the surface of the heating element.

[0038] Please refer to Figure 3 A transmission disc 7 is rotatably mounted on one side of the fan cover 301 close to the noise reduction ring 502 , and the transmission disc 7 is in transmission connection with the noise reduction ring 502 .

[0039] Specifically, in order to adjust the use position of the noise reduction ring 502 and to adjust whether the docking interface 503 inside the noise reduction ring 502 is aligned with the exhaust port 501, the transmission disk 7 is rotated, and the transmission disk 7 is transmitted to the transmission groove on the inner wall of the noise reduction ring 502, so that the noise reduction ring 502 can be caused to rotate. When the noise reduction ring 502 rotates to align the internal docking interface 503 with the exhaust port 501, the wind generated by the fan mechanism 4 can be discharged through the docking interface 503 and the inside of the exhaust port 501. When the docking interface 503 is staggered with the exhaust port 501, the wind discharged by the fan mechanism 4 cannot be discharged. At the same time, the exhaust port 501 at some positions is blocked by the noise reduction ring 502, so that the wind can be discharged through the docking interface 503 at the specified position and the inside of the exhaust port 501, so that the positions of the exhaust port 501 and the docking interface 503 can be adjusted, so that the wind generated by the fan mechanism 4 is discharged through the specified exhaust port 501.

[0040] Please refer to Figure 5 and Figure 6 A fixing seat 6 is fixedly installed on the front of the fan cover 301 , a spring 601 is installed inside the fixing seat 6 , and a positioning pin 602 is movably installed inside the spring 601 .

[0041] Please refer to Figure 5 and Figure 6 A positioning hole 701 is provided inside the shaft core of one end of the transmission plate 7 close to the fixing seat 6, one end of the positioning pin 602 is located inside the positioning hole 701, and one end of the fixing seat 6 close to the positioning hole 701 is inclined.

[0042] Specifically, in order to fix the position of the transmission disk 7, when the transmission disk 7 starts to rotate forward, its edge will come into contact with the positioning pin 602 and produce extrusion. As a movable component with a certain rigidity, the positioning pin 602 will move toward the inside of the fixed seat 6 under the action of this extrusion force. At the same time, the spring 601 behind the positioning pin 602 begins to play a role. It is compressed and stores energy to prepare for the subsequent resetting action. As the transmission disk 7 continues to rotate, the interaction between the positioning pin 602 and the spring 601 will continue until the transmission disk 7 stops rotating. At this time, the spring 601 begins to release the energy stored previously, pushing the positioning pin 602 to move in the opposite direction, that is, to the outside of the fixing seat 6. This movement process continues until one end of the positioning pin 602 is just aligned with the positioning hole 701 on the transmission disk 7 and smoothly enters it. Once the positioning pin 602 is inserted into the positioning hole 701, the position of the transmission disk 7 is firmly fixed. Due to the close fit between the positioning pin 602 and the positioning hole 701, the transmission disk 7 can no longer rotate in any form at this time, so that the position of the transmission disk 7 can be fixed.

[0043] Please refer to Figure 7 A magnetic block 5021 is installed on the outer surface of the noise reduction ring 502 close to the docking port 503 , and a magnetic column 5022 is installed on the inner wall of the fan housing 3 close to the exhaust port 501 .

[0044] Specifically, in order to monitor the moving position of the noise reduction ring 502, when the noise reduction ring 502 rotates, the magnetic block 5021 will rotate along with it. When the magnetic block 5021 contacts the magnetic column 5022, a repulsive force will be generated between them. At this time, the magnetic column 5022 will be lifted up, thereby providing a prompt for whether the exhaust port 501 and the docking port 503 are aligned, thereby facilitating the worker to make timely adjustments.

[0045] Please refer to Figure 7 An air inlet 5023 is provided inside the magnetic block 5021 , and a duct 5024 is installed inside the fan housing 3 near the magnetic block 5021 , and an air outlet end of the duct 5024 is located outside the power source of the fan mechanism 4 .

[0046] Specifically, in order to improve the heat dissipation effect of the motor 401 and extend its service life, when the magnetic block 5021 contacts the magnetic column 5022, the magnetic column 5022 will be lifted up to expose the air inlet end of the duct 5024. At this time, the air inlet 5023 is connected to the internal road of the duct 5024. When the fan mechanism 4 is working, part of the wind generated will be transported to the duct 5024 through the inside of the air inlet 5023. When the wind is discharged from the air outlet end of the duct 5024, the outside of the motor 401 can be cooled, thereby extending its service life.

[0047] Please refer to Figure 3 A windshield plate 3012 is rotatably mounted on one side of the fan cover 301 close to the fan housing 3 . A through hole 3013 is correspondingly arranged inside the windshield plate 3012 close to the air outlet 302 . A screw 3011 is mounted on the windshield plate 3012 passing through the inside of the fan cover 301 .

[0048] Specifically, in order to close and open the air outlet 302 inside the fan cover 301, the worker rotates the screw 3011 to rotate the screw 3011 through the threaded structure, and then drives the wind shield 3012 to rotate. When the opening 3013 inside the wind shield 3012 is aligned with the air outlet 302, the wind generated by the fan mechanism 4 can be discharged through the air outlet 302. When the opening 3013 inside the wind shield 3012 is staggered with the air outlet 302, the wind shield 3012 will block the air outlet 302. At this time, the wind generated by the fan mechanism 4 cannot be discharged from the air outlet 302 inside the fan cover 301, so that the air discharge surface of the fan mechanism 4 can be adjusted to achieve the function of closing and opening the air outlet 302 inside the fan cover 301.

[0049] Please refer to Figure 3 A scraper plate 3014 is provided on one side of the wind shield 3012 close to the fan cover 301. The scraper plate 3014 is offset from the air outlet 302 when in a stationary state. The scraper plate 3014 is used to process the air outlet 302. The scraper plate 3014 is in contact with the fan cover 301. The scraper plate 3014 is made of a soft but wear-resistant material, which may be wear-resistant rubber.

[0050] Specifically, in order to close and open the air outlet 302 inside the fan cover 301, the worker rotates the screw 3011 to rotate the screw 3011 through the threaded structure, and then drives the wind shield 3012 to rotate. When the opening 3013 inside the wind shield 3012 is aligned with the air outlet 302, the wind generated by the fan mechanism 4 can be discharged through the air outlet 302. When the opening 3013 inside the wind shield 3012 is staggered from the air outlet 302, the wind shield 3012 will block the air outlet 302, and the wind generated by the fan mechanism 4 cannot be discharged from the air outlet 302 inside the fan cover 301. 2 discharge, so that the surface of the fan mechanism 4 for discharging wind can be adjusted to realize the function of closing and opening the air outlet 302 inside the fan cover 301. When the wind shield 3012 rotates, the wind shield 3012 will drive the scraper 3014 to move. As the wind shield 3012 rotates, the scraper 3014 wipes and cleans along the contour of the air outlet 302. In this process, the scraper 3014 can effectively remove impurities such as dust and dirt attached to the surface of the air outlet 302, ensuring that the inside of the air outlet 302 is always kept clean and unobstructed, thereby preventing dust from clogging the inside of the air outlet 302 and affecting the delivery of wind.

[0051] Please refer to Figure 4 The support base 1 includes a base plate 101 and a support rod 102 . The support rod 102 is rotatably mounted on the top of the base plate 101 , and the top of the support rod 102 is connected to the fan housing 3 .

[0052] Specifically, in order to support the fan casing 3, the fan cover 301 and the fan mechanism 4, the base plate 101 is used to support the top support rod 102, the interior of the base plate 101 is connected to the support rod 102 through a motor assembly, and the output end of the motor assembly is connected to the support rod 102. The support rod 102 is driven to rotate by the motor assembly, so that the position of the air outlet surface of the fan mechanism 4 can be adjusted, and the fan casing 3, the fan cover 301 and the fan mechanism 4 can be supported by the base plate 101 and the support rod 102.

[0053] Please refer to Figure 4 A threaded rod 2 is installed inside the bottom plate 101 through a thread, and a suction cup 201 is installed at the bottom end of the threaded rod 2. The suction cup 201 has excellent sealing and adsorption capabilities.

[0054] Specifically, in order to fix the use position of the device, the worker manually drives the threaded rod 2 to rotate, and uses the spiral propulsion force generated between the precisely machined threaded structure on its outer side and the base plate 101 to enable the threaded rod 2 to achieve precise movement control in the vertical direction. As the threaded rod 2 rotates and rises or falls, the suction cup 201 connected to its bottom end also moves accordingly. When the suction cup 201 is in close contact with a desktop, the ground or other flat surface, a strong suction force can be quickly formed between the suction cup 201 and the contact surface through manual squeezing operation. This suction force can not only effectively resist the weight of the device, but also cope with certain lateral forces and impact forces, thereby ensuring the stability of the device in a fixed position, thereby fixing the use position of the device. When the device needs to be moved or rearranged, the worker only needs to rotate the threaded rod 2 in the opposite direction to release the suction force of the suction cup 201, and the device can be easily removed from the fixed position.

[0055] Working principle: the worker rotates the threaded rod 2 to move the threaded rod 2 through the outer threaded structure, and the bottom end of the threaded rod 2 will drive the suction cup 201 to move. The suction force generated by the suction cup 201 and the desktop or the ground can fix the use position of the device. Then, the screw 3011 is rotated to rotate the screw 3011 through the threaded structure, and then the windshield 3012 is driven to rotate so that the opening 3013 inside the windshield 3012 is aligned with the air outlet 302. Then, the transmission disk 7 is rotated, and the transmission disk 7 is transmitted to the transmission groove on the inner wall of the noise reduction ring 502. The noise reduction ring 502 rotates to align the internal docking interface 503 with the exhaust port 501. When the noise reduction ring 502 rotates, the magnetic block 5021 will rotate along with it. When the magnetic block 5021 contacts the magnetic column 5022, a repulsive force will be generated between them. At this time, the magnetic column 5022 will be lifted up, which can align the exhaust port 501. 01 and the docking interface 503 serve as a prompt for it. When the transmission disk 7 rotates forward, the transmission disk 7 will squeeze the positioning pin 602, and the positioning pin 602 will squeeze the spring 601. The spring 601 is compressed inside the fixed seat 6. When the transmission disk 7 stops rotating, the positioning pin 602 will move inside the fixed seat 6 under the action of the spring 601. When one end of the positioning pin 602 is located inside the positioning hole 701, the transmission disk 7 can be positioned, and then the motor 401 works. The output end of the motor 401 will drive the fan blades 402 to rotate. The rotation of the fan blades 402 can accelerate the flow of surrounding air. When the fan blades 402 rotate, they will cut the air and promote the flow of air. The wind generated by the fan blades 402 can be discharged through the docking interface 503 and the exhaust port 501, so as to achieve the effect of multi-directional air outlet, so as to better achieve the purpose of heat dissipation.

[0056] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
