Description

Technical Field

[0001] The utility model relates to the technical field of fans, and in particular to a fan structure with a foreign body prevention function. Background Art

[0002] With the development of modernization, transportation has become more and more convenient, and people's means of transportation have become more diverse. Among them, cars are a common means of transportation. In order to facilitate charging, cars are usually equipped with wireless charging modules for charging electronic devices. Wireless charging modules generally include wireless charging components and cooling fans. Since the installation position of the wireless charging module is located in the cockpit, it is inevitable that foreign matter will enter the cooling fan during use, causing damage to the cooling fan blades or even blocking, affecting the cooling effect.

[0003] Existing heat dissipation fans are usually provided with a foreign body anti-structure at the air outlet, but this structure cannot effectively prevent foreign bodies from entering the fan blades, and may also affect the output of air volume and reduce the heat dissipation effect. Utility Model Content

[0004] The utility model aims to provide a fan structure with a foreign body protection function, which can greatly reduce the risk of foreign bodies entering the fan, causing fan damage or stalling, while improving the heat dissipation effect.

[0005] A fan structure with a foreign body protection function comprises a shell and a fan arranged in the shell, the shell is provided with an air outlet, an air outlet channel is formed between the air outlet and the fan, the air outlet channel is arranged obliquely, at least one foreign body port is provided near the lower end of the air outlet channel, the foreign body port connects the air outlet channel and the outside of the shell, and a plurality of protrusions are provided on one side of the foreign body port adjacent to the fan.

[0006] In the above technical solution, the air outlet is used to guide the airflow generated by the fan to the external environment, and an air outlet channel is formed between the air outlet and the fan, so that the airflow generated by the fan can flow to the air outlet through the air outlet channel, and then blow air to the electronic equipment for heat dissipation. The air outlet channel is tilted to enhance the guiding property, which helps to achieve specific wind direction control, so that the airflow generated by the fan can be blown out smoothly, increasing the practicality of the fan. The foreign object port is connected to the air outlet channel and is arranged below the air outlet channel, reducing the risk of fan damage or performance degradation caused by foreign objects entering the shell. Specifically, when foreign objects enter the shell, the foreign objects fall to the outside of the shell after reaching the foreign object port along the tilt direction of the air outlet channel under the action of gravity. If they cannot fall in time, since a number of protrusions are provided on one side of the foreign object port adjacent to the fan, the protrusions provided at the foreign object port can form a physical barrier to block foreign objects in time, prevent foreign objects from entering the fan, causing fan damage or stalling, and improve the reliability and service life of the fan.

[0007] Furthermore, the foreign object opening is arranged along the width direction of the air outlet passage.

[0008] In the above technical solution, the foreign object opening is located below the air outlet channel and is arranged along the width direction of the air outlet channel, so that the foreign object opening can cover a wider area, thereby increasing the chances of capturing and guiding foreign objects. At the same time, it ensures that no matter which direction the foreign objects enter the housing, there is a greater possibility that they will be guided into the foreign object opening, rather than directly blocking the air outlet channel or the inside of the fan, which significantly enhances the foreign object prevention function.

[0009] Furthermore, a baffle is provided on one side of the foreign object opening adjacent to the fan, the baffle extends along the length direction of the foreign object opening, and the protrusions are arranged side by side on the baffle.

[0010] In the above technical solution, a baffle is arranged on the side of the foreign object opening adjacent to the fan, and the protrusions are arranged side by side on the baffle, which can form an effective physical barrier to prevent foreign objects from entering the interior of the fan. At the same time, the setting of the baffle enhances the structural stability of the protrusions and further improves the foreign object prevention function.

[0011] Furthermore, the foreign object opening is provided with a plurality of partitions, and the two ends of the partitions are respectively connected to the air outlet channel and the baffle.

[0012] In the above technical solution, by setting a plurality of partitions, the foreign body opening can be divided, so that the foreign body opening can effectively block foreign bodies of different sizes, enhance the foreign body blocking ability of the foreign body opening, and ensure that foreign bodies of different sizes are effectively blocked in the foreign body opening instead of entering the fan. At the same time, by setting the partitions, the foreign body opening and its surrounding structures are more solid and stable, and can withstand greater external impact and vibration.

[0013] Furthermore, a gap is formed between two adjacent protrusions.

[0014] In the above technical solution, appropriate gap design can ensure that when the fan is running, the airflow generated by the fan is allowed to pass smoothly, ensuring that the air volume and air pressure of the fan meet the design requirements and its air output efficiency will not be affected by excessive obstruction.

[0015] Furthermore, the housing includes a bottom shell and an upper cover, and the bottom shell and the upper cover are detachably connected to form an installation cavity for installing the fan.

[0016] In the above technical solution, the fan is arranged in the installation cavity formed by the connection of the bottom shell and the upper cover, which can ensure the stable installation and good operation of the fan. At the same time, the design of the bottom shell and the upper cover that can be detachably connected makes the assembly, maintenance and cleaning of the shell and the fan more convenient. When in use, different shells and fans can also be replaced according to different usage requirements, which increases the flexibility and applicability of the utility model.

[0017] Furthermore, the bottom shell is provided with a plurality of mounting holes.

[0018] In the above technical solution, a plurality of mounting holes are provided on the bottom shell, so that the fan can be conveniently fixed on other equipment or structures. The mounting holes can be positioned and the number can be adjusted according to specific needs to meet the fixing requirements of different application scenarios. The design of the mounting holes can also ensure that the fan remains stable during operation and reduce vibration and noise.

[0019] Furthermore, the bottom shell is provided with an air inlet, and the air inlet is opposite to the fan.

[0020] In the above technical solution, an air inlet opposite to the fan is arranged on the bottom shell, which can ensure that the fan obtains sufficient air intake and improve the heat dissipation effect and performance of the fan.

[0021] Furthermore, the air inlet is provided with a plurality of ribs, and the ribs form a cross-shaped structure.

[0022] In the above technical solution, the arrangement of ribs at the air inlet can enhance the stability of the air inlet structure and prevent foreign objects such as dust and small particles from directly entering the fan to a certain extent. The ribs are combined in a certain arrangement to form a cross-shaped structure, which makes the air flow at the air inlet more uniform and reduces the turbulence of the air flow. Through the guidance of the ribs, the air can enter the fan more smoothly and exchange with the hot air, thereby improving the heat dissipation effect.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] 1. The air outlet channel is tilted so that the airflow generated by the fan can flow to the air outlet through the tilted air outlet channel, and then blow to the electronic equipment for heat dissipation.

[0025] 2. The foreign object port is connected to the air outlet and is arranged below the air outlet passage, so that after the foreign object enters the shell, it can reach the foreign object port along the inclined direction of the air outlet passage and then fall out of the shell.

[0026] 3. There are several protrusions on the side of the foreign object port adjacent to the fan. When the foreign object cannot fall out of the shell in time, the protrusions on the foreign object port can form a physical barrier to block the foreign object and prevent it from entering the fan, avoiding damage to the fan or blocking the rotation.

[0034] The fan structure with the function of preventing foreign matter of the utility model will be further described in detail below in combination with specific embodiments and drawings. The drawings show a preferred embodiment of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0035] Please refer to Figures 1 to 3 In a preferred embodiment, the fan structure with anti-foreign object function of the utility model includes a shell 1 and a fan 2 arranged in the shell 1, the shell 1 is provided with an air outlet 101, an air outlet channel 3 is formed between the air outlet 101 and the fan 2, the air outlet channel 3 is arranged obliquely, and at least one foreign object port 102 is provided near the lower end of the air outlet channel 3, the foreign object port 102 connects the air outlet channel 3 and the outside of the shell 1, and a plurality of protrusions 4 are provided on one side of the foreign object port 102 adjacent to the fan 2.

[0036] like Figure 3 As shown, the airflow generated by the fan 2 passes through the air outlet channel 3 to the air outlet 101. If a foreign object enters the air outlet housing 1, the foreign object first reaches the air outlet channel 3. Since the foreign object port 102 is connected to the air outlet 101 and is arranged below the air outlet channel 3, the foreign object will directly reach the foreign object port 102 along the air outlet channel 3 after entering the housing 1, and then fall out of the housing 1, avoiding the foreign object falling into the fan 2 and affecting it. At the same time, when the foreign object cannot be discharged in time after reaching the foreign object port 102, a number of protrusions 4 are provided on the side of the foreign object port 102 adjacent to the fan 2. These protrusions 4 will form a physical barrier to block the foreign object, preventing the fan 2 from being damaged or blocked by these foreign objects.

[0037] It can be seen from the above technical solution that an air outlet channel 3 is formed between the air outlet 101 and the fan 2, so that the airflow generated by the fan 2 can flow to the air outlet 101 through the air outlet channel 3, and then blow air to the electronic device for heat dissipation. The air outlet channel 3 is tilted, which helps to achieve specific wind direction control, so that the airflow generated by the fan 2 can be blown out smoothly, increasing the practicality of the fan 2. The foreign body port 102 is connected to the air outlet 101 and is arranged below the air outlet channel 3, reducing the risk of damage or performance degradation of the fan 2 caused by the entry of foreign objects. Specifically, when foreign objects enter, the foreign objects will reach the foreign object port 102 along the tilt direction of the air outlet channel 3 and fall out of the housing 1. If they cannot fall in time, since a number of protrusions 4 are provided on one side of the foreign object port 102 adjacent to the fan 2, the protrusions 4 provided on the foreign object port 102 form a physical barrier to block foreign objects in time, prevent foreign objects from entering the fan 2, causing damage or stalling of the fan 2, and improve the reliability and service life of the fan 2.

[0038] Please refer to Figure 1 and Figure 3 , the foreign object port 102 is arranged along the width direction of the air outlet channel 3. The foreign object port 102 is located below the air outlet channel 3 and is arranged along the width direction of the air outlet channel 3, so that the foreign object port 102 can cover a wider area, thereby increasing the chance of capturing and guiding foreign objects. No matter which direction the foreign objects enter from, there is a greater possibility that they will be guided into the foreign object port 102, rather than being directly blocked in the air outlet channel 3 or inside the fan 2, which significantly enhances the foreign object prevention function. At the same time, the unobstructedness of the air outlet channel 3 can be maintained, ensuring that the wind flow generated by the fan 2 can smoothly pass through the air outlet channel 3 and be discharged. The foreign object port 102 will not significantly affect the flow of the wind flow, so the ventilation efficiency can be maintained.

[0039] At the same time, a baffle 5 is provided on the side of the foreign object opening 102 adjacent to the fan 2, and the baffle 5 extends along the length direction of the foreign object opening 102, and the protrusions 4 are arranged side by side on the baffle 5. The baffle 5 is provided on the side of the foreign object opening 102 adjacent to the fan 2, and the protrusions 4 are arranged side by side on the baffle 5, which can form an effective physical barrier, effectively preventing foreign objects from entering the fan 2, and further enhancing the foreign object prevention function. At the same time, the design of the baffle 5 makes the structure of the protrusion 4 more stable, thereby increasing the stability of blocking foreign objects and improving the foreign object prevention effect.

[0040] Exemplarily, a gap 6 is formed between two adjacent protrusions 4, and a proper design of the gap 6 can ensure that the fan will not affect its air outlet efficiency due to excessive obstruction when it is running. The gap design between adjacent protrusions 4, although reducing the area of ​​direct obstruction, can make foreign matter blocked and dispersed in multiple directions when passing through, increasing the possibility of foreign matter being captured and blocked. By designing the size and number of the gap 6, a "maze-like" blocking structure can be formed, so that when foreign matter tries to enter the inside of the fan 2, it must bypass multiple protrusions 4 and gaps 6, thereby greatly increasing its difficulty. These gaps 6 allow the airflow generated by the fan 2 to pass smoothly, ensuring that the air volume and wind pressure of the fan 2 meet the design requirements. At the same time, if foreign matter is caught in the gap 6, the user can easily remove the foreign matter from the gap 6 through simple operations, such as using a brush or a blowing tool, so as to keep the fan 2 clean and perform well. Compared with a completely enclosed structure, the design with gaps 6 is more convenient and quicker to clean and maintain. During specific implementation, the designer can flexibly adjust the size and shape of the protrusion 4 and the size of the gap 6 to enhance the foreign body prevention effect and air outlet efficiency of the utility model to meet different usage requirements.

[0041] In addition, the foreign body port 102 is provided with a plurality of partitions 9, and the two ends of the partitions 9 are respectively connected to the air outlet channel 3 and the baffle 5. By setting a plurality of partitions 9, the foreign body port 102 is divided, so that the foreign body port 102 has sufficient foreign body blocking ability, can effectively block foreign bodies of different sizes, and ensure that foreign bodies are effectively blocked in the foreign body port 102 instead of entering the inside of the fan 2. At the same time, through the setting of the partitions 9, the foreign body port 102 and its surrounding structures are more solid and stable, and can withstand greater external impact and vibration. It should be noted that the shape, size and number of the partitions 9 are not limited, and the shape, size and number can be adjusted according to specific needs to meet the needs of different application scenarios.

[0042] Please refer to Figures 1 to 3The housing 1 includes a bottom housing 103 and an upper cover 104, which are detachably connected to form an installation cavity 7 for installing the fan 2. The bottom housing 103 and the upper cover 104 are detachably connected, so that the assembly and maintenance process of the fan 2 becomes simple and convenient. The user can easily disassemble the housing 1, replace the fan 2, clean the internal dust or perform other maintenance operations without using complex tools or professional skills. The fan 2 may accumulate dust and dirt during use, affecting the performance and service life of the fan 2. By disassembling the bottom housing 103 and the upper cover 104, the user can thoroughly clean the inside and outside of the fan 2 to keep the fan 2 clean and hygienic. The detachable connection between the bottom housing 103 and the upper cover 104 can ensure the sealing of the installation cavity 7, reduce air leakage, and thus improve the ventilation performance of the fan 2. At the same time, the gap between the bottom housing 103 and the upper cover 104 can be adjusted as needed to meet different ventilation requirements.

[0043] At the same time, the bottom shell 103 is provided with a plurality of mounting holes 1031. The design of the mounting holes 1031 enables the fan 2 to be easily installed on various devices or structures. The user can fix the fan 2 at the desired position by screws or other fasteners to ensure the stability and safety of the fan 2. The plurality of mounting holes 1031 are provided so that the installation position of the fan 2 can be adjusted according to actual needs. The user can select the appropriate position of the mounting holes 1031 according to the heat dissipation requirements, space limitations or other factors to achieve a flexible installation layout. The design of the mounting holes 1031 can also ensure that the fan 2 remains stable during operation and reduces vibration and noise. Exemplarily, the mounting holes 1031 of this embodiment are provided with four, and are respectively located at the corners of the housing 1. When the fan 2 needs to be disassembled or repaired, the fan 2 can be easily disassembled through the mounting holes 1031, and the inside of the fan 2 can be easily accessed for cleaning, replacement of parts and other maintenance work.

[0044] Furthermore, the bottom case 103 is provided with an air inlet 1032, which is opposite to the fan 2. The design of the air inlet 1032 being opposite to the fan 2 reduces the resistance to air flow, ensures that the fan 2 can directly inhale a large amount of cold air from the air inlet 1032 when rotating, so that the fan 2 can work with higher efficiency, which helps to optimize the heat dissipation effect, because the cold air can directly and efficiently enter the inside of the fan 2 and exchange with the hot air inside the device.

[0045] like Figure 4As shown, the air inlet 1032 of this embodiment is provided with a plurality of ribs 10, and the ribs 10 form a cross-shaped structure. The ribs 10 provided at the air inlet 1032 can enhance the stability of the structure of the air inlet 1032, and can also prevent larger foreign objects from directly entering the fan 2 to a certain extent, causing damage to the fan 2. At the same time, the ribs 10 are combined together in a certain arrangement manner, and finally form a cross-shaped structure, so that the air flow of the air inlet 1032 is more uniform, and the turbulence of the air flow is reduced. Through the guidance of the ribs 10, more cold air can be sucked into the fan 2, mixed and exchanged with the hot air inside the device, and further improve the heat dissipation performance.
