[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0026] Example 1:
[0027] This embodiment provides a detachable blade fan, such as... Figures 1-2 As shown, the device includes a main body 1, a fixing member 2, and multiple fan blades 3. One end of each fan blade 3 has a first engaging portion 31, and the main body 1 has multiple second engaging portions 11 adapted to the first engaging portion 31. The multiple second engaging portions 11 are evenly distributed around the main body 1, and the multiple fan blades 3 are connected to the main body 1 by engaging the first engaging portion 31 onto the second engaging portions 11. The fixing member 2 is connected to the main body 1 and abuts against the first engaging portions 31 of the multiple fan blades 3. The number of fan blades 3 can be three, four, etc. Preferably, the main body 1 is connected to three fan blades 3. Since the multiple fan blades 3 have the same shape, only one mold is needed, reducing production costs.
[0028] In this embodiment, the detachable fan blades are easily connected by snapping multiple fan blades 3 to the main body 1, and then connected to the main body 1 by the fastener 2, which further strengthens the connection between the multiple fan blades 3 and the main body 1.
[0029] Compared to traditional fans, the detachable blade fan in this embodiment does not require each blade to be fixed to the main body with screws, making it easy to assemble and disassemble. When not in use or during transportation, the blades can be easily removed from the main body 1, reducing transportation and storage space and making transportation and storage convenient.
[0030] As a preferred embodiment, such as Figure 1 As shown, the first snap-fit part 31 is a snap-fit groove, and the second snap-fit part 11 is a snap-fit block. The snap-fit groove snaps onto the snap-fit block. The shape and size of the snap-fit groove and the snap-fit block are compatible, and the snap-fit block can be a hollow structure. The fan blade 3 and the main body 1 are snapped together by the snap-fit groove and the snap-fit block, making assembly and disassembly convenient.
[0031] Additionally, it should be noted that the first snap-fit part 31 can be a snap-fit block, and the second snap-fit part 11 can be a snap-fit groove, so that the first snap-fit part 31 and the second snap-fit part 11 can be adapted to each other when snapping.
[0032] In a preferred embodiment, both ends of the first engaging portion 31 protrude from the blade surface of the fan blade 3. For example... Figure 1 As shown, the first snap-fit part 31 has one end with a snap-fit interface protruding from the bottom surface of the fan blade 3, and the other end of the first snap-fit part 31 opposite to the snap-fit interface protruding from the top surface of the fan blade 3, so as to facilitate the snap-fit of the first snap-fit part 31 and the second snap-fit part 11. In addition, the end of the first snap-fit part 31 opposite to the snap-fit interface can abut against the fixing member 2 to make the fan blade more secure.
[0033] Preferably, as shown in Figure 4 The first clamping part 31 is provided with a plurality of reinforcing ribs 32 along the length of the fan blade, which play a balancing role.
[0034] As a preferred embodiment, the second clamping part 11 has multiple sides and at least one corner, so that when the first clamping part 31 is clamped with the second clamping part 11, the fan blade cannot rotate relative to the main body 1, further improving the stability of the fan blade connection.
[0035] As a preferred embodiment, the second clamping part 11 is fan-shaped or polygonal. The second clamping part 11 can also be triangular, quadrilateral, etc. When the second clamping part 11 is fan-shaped, the angle of the fan points to the center of the main body 1 to avoid the fan blade rotating relative to the main body.
[0036] As a preferred embodiment, as shown in Figure 1 and Figure 2 The fixing part 2 includes a connecting part 22 and a limiting plate 21. The connecting part 22 is in a cylindrical structure with one end open, and the limiting plate 21 is connected in a ring shape around the connecting part 22, and the axis of the connecting part 22 is perpendicular to the plate surface of the limiting plate 21. The connecting part 22 is connected with the main body 1, and the limiting plate 21 abuts against the first clamping part 31 of the plurality of fan blades 3. The diameter of the limiting plate 21 of the fixing part 2 is equal to the diameter of the main body 1, and the appearance is more neat.
[0037] The fixing part 2 in this embodiment is connected with the main body 1 through the connecting part 22, and the first clamping part 31 is limited by the limiting plate 21, thereby ensuring the stability of the connection between the plurality of fan blades and the main body 1, and avoiding the fan blades from falling off.
[0038] As a preferred embodiment, a connecting mouth 12 is provided in the middle of the main body 1, which is in a cylindrical structure matched with the connecting part 22. An external thread is provided on the outside of the connecting mouth 12, and an internal thread is provided on the inside of the connecting part 22, and the connecting part 22 is connected with the connecting mouth 12 through the threads. The second clamping part 11 is uniformly distributed around the connecting mouth 12. In addition, an internal thread can also be provided on the inside of the connecting mouth 12, and an external thread is provided on the outside of the connecting part 22, so that the connecting part 22 is connected with the connecting mouth 12 through the threads. The internal thread on the inside of the connecting part 22 can be a full thread provided along the entire circumference of the connecting part 22, or a threaded segment provided on both sides of the connecting part 22.
[0039] The fixing part 2 in this embodiment is connected with the main body 1 through threads, which is convenient to connect and firmly fixed.
[0040] Preferably, as shown in Figure 3As shown, the internal thread 221 is a threaded segment arranged on both sides of the connecting portion 22, that is, the internal thread is a discontinuous threaded segment, preferably, an odd number of threaded segments, such as 3, are arranged on one side of the connecting portion 22, and an even number of threaded segments, such as 4, are arranged on the other side, which can provide higher locking stability and stronger shear force bearing capacity, reduce vibration friction, and make the connection more stable.
[0041] As a preferred embodiment, as shown in the drawings, Figure 1 As shown, a plurality of reinforcing ribs 23 are arranged on one side of the limiting plate 21 close to the main body 1, and the plurality of reinforcing ribs 23 are arranged in multiple circles around the outside of the connecting nozzle 12. A plurality of diverging ribs are arranged between the plurality of reinforcing ribs 23 and diverge outwardly from the center of the connecting nozzle 12. The reinforcing ribs 23 and the diverging ribs can increase the friction between the fixing member 2 and the first clamping portion 31, so that the fixing member 2 and the first clamping portion 31 are clamped more stably.
[0042] As a preferred embodiment, as shown in the drawings, Figure 2 As shown, a plurality of air holes 24 are arranged on the bottom plate of the connecting portion 22, and the bottom plate of the connecting portion 22 is in the same plane as the limiting plate 21. The air holes 24 can facilitate heat dissipation.
[0043] As a preferred embodiment, a plurality of anti-skid strips 25 are arranged on the side of the limiting plate 21 away from the main body 1, and the anti-skid strips 25 are arranged divergingly around the center of the bottom plate of the connecting portion 22. The anti-skid strips 25 can be arranged in different patterns. The anti-skid strips 25 can facilitate the rotation of the fixing member 2 to facilitate the installation on the main body 1.
[0044] The above only describes the preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make some modifications and improvements without departing from the creative concept of the present application, which should be covered within the protection scope of the present application.
