[0033] in;
[0034] The ventilation fan assembly 100 includes a ventilation fan housing 110, with retaining rings 120 tightly welded to both sides of the ventilation fan housing 110, and a grid 130 bolted to the side of the retaining rings 120. A motor base 140 is tightly welded to the inner cavity of the ventilation fan housing 110, and a motor leg 150 is bolted to the motor base 140. A motor 160 is tightly welded to the top of the motor leg 150, and a fan 170 is fitted onto the output end of the motor 160.
[0035] The base assembly 200 includes a fixing block 210 disposed at the bottom of the outer circumferential wall of the fan housing 110, a base 220 sleeved on the bottom of the fixing block 210, an extension block 230 tightly welded to both sides of the base 220, a housing 250 tightly welded to both sides of the base 220, and a pull rod 260 sleeved inside the housing 250.
[0036] The support assembly 300 includes a support base 310 disposed at the bottom of the outer circumference of the fan housing 110. Fixing blocks 320 are tightly welded to both sides of the support base 310. Multiple support legs 330 are bolted to both sides of the support base 310. A support top shell 360 is snapped to the top of the support base 310. Fixing blocks 370 are tightly welded to both sides of the support top shell 360.
[0037] Meanwhile, to ensure a more secure fixation of the fan 170, a ring-shaped array of holes is provided on the side of the fan 170, and screws 180 are threaded into the holes.
[0038] Furthermore, in order to enable quick installation of the fixing block 210, specifically, the bottom of the fixing block 210 is tightly welded with multiple protruding blocks, the top of the base 220 is provided with multiple square slots, the size of the square slots is matched with the protruding blocks, and the side of the base 220 is threaded with multiple pins 240.
[0039] It is worth noting that, for better results, specifically, a drill bit 270 is tightly welded to the bottom of the pull rod 260, a handle is tightly welded to the outer circumference of the pull rod 260, and a spring 280 is fitted on the outer circumference of the drill bit 270.
[0040] It is worth noting that, for better performance, the outer casing 250 has a strip-shaped groove on its side, and the lower half of the strip-shaped groove has a fixing groove. The size of the strip-shaped groove and the fixing groove are matched with the size of the handle.
[0041] When the ventilator housing 110 needs to be fixed, the fixing block 210 at the bottom of the ventilator housing 110 is engaged with the base 220 through the protruding block. Then, the pin 240 passes through the engagement between the base 220 and the fixing block 210. The end of the pin 240 is threaded and is threaded to the through hole of the base 220. The protruding horizontal block on the side of the pin 240 is used to rotate and unscrew it. The extension blocks 230 on both sides of the base 220 are used to increase the overall support of the base 220. Then, using the anchor points composed of the pull rod 260, drill bit 270 and spring 280 in the housing 250 on both sides of the base 220, the handle is pressed down to drive the spring 280 at the bottom of the pull rod 260 to be fixed in the ground. Then, the pull rod 260 is rotated to make the handle engage with the groove on the housing 250, thus completing the fixing process. When it is necessary to disassemble, the pull rod 260 is rotated in the opposite direction. At that time, the force stored in the spring 280 will drive the pull rod 260 to return to its original position.
[0042] Next, for better results, specifically, a groove is provided on the top of the first fixing block 320, and a protruding locking block is tightly welded to the bottom of the second fixing block 370. The size of the groove matches the size of the protruding locking block, and a locking chain 380 is installed on the top of the second fixing block 370.
[0043] Subsequently, for better results, specifically, an extension block 340 is installed on the side of the support leg 330, and a crossbar 350 is tightly welded to the side of the support leg 330.
[0044] When the outer circumferential wall of the fan housing 110 is engaged with the support base 310, the support base 310 and the support top shell 360 are made of lightweight materials. The support base 310 is engaged with the support top shell 360 by the fixing blocks 320 on both sides of the support base 310 and the fixing blocks 370 on both sides of the support top shell 360. Then, the fixing blocks 320 and 370 are fixed by the chain 380. The support base 310 and the support top shell 360 fix the fan housing 110. The two sides of the support base 310 are supported by the support members composed of the support legs 330, the extension block 340 and the crossbar 350, thereby greatly reducing the vibration amplitude of the fan housing 110.
[0045] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0046] The models of the devices or equipment mentioned in this article are as follows:
[0047] Motor 160: T35-11.
[0048] Working principle:
[0049] When the device is in operation, the motor 160 starts working after the power is turned on, driving the fan 170 to rotate. The fan 170 has a ring-shaped array of holes on its side, and screws 180 inside the holes ensure the fan blades are secure, thus achieving efficient airflow propulsion. As the fan 170 rotates, air is drawn into the ventilator housing 110 and initially filtered through the grid 130, blocking anything that could damage the fan 170 and ensuring human safety. Subsequently, the airflow is accelerated and discharged from the ventilator by the power generated by the motor 160, forming a continuous airflow cycle. The ventilator is securely installed using the base assembly 200 and the support assembly 300. The fixing block 210 in the base assembly 200 and the base 220 are connected by pins 240. The design of the pull rod 260 and drill bit 270 inside the housing 250 allows the user to easily adjust the installation position of the ventilator and ensures its stability. The support base 310 and support leg 330 in the support assembly 300 provide additional support force and are firmly connected to the support top shell 360 through fixing block one 320 and fixing block two 370. Together, they stabilize the fan housing 110. Through the above design, the goal of quick disassembly and assembly, good stability, and reduced fan vibration is achieved to meet the usage needs in different scenarios.
