[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] refer to Figure 1 to Figure 8The first aspect of the present invention protects an anti-blocking structure, which includes a one-way valve 11 and an ejection assembly. The one-way valve 11 can be arranged on the side of the intake pipe, and the one-way valve 11 can introduce external gas into the intake pipe. The one-way valve 11 is a conventional commercially available part, and the intake pressure of the one-way valve 11 is adjustable to ensure that the intake pressure of the one-way valve 11 is greater than the intake pressure of the intake pipe, so that the one-way valve 11 works only when the intake pipe is blocked.

[0041] The ejection assembly includes a rotatable bearing ring 12 and a telescopic member 13. When the bearing ring 12 rotates, the telescopic member 13 can be driven to repeatedly telescope. When the one-way valve 11 is inlet, the gas can push the bearing ring 12 to rotate.

[0042] The present invention sets a one-way valve 11. When the air inlet of the air inlet pipe is blocked by flying objects, air is introduced into the compressor body through the one-way valve 11. On the one hand, it can prevent the compressor body from being damaged due to the inability to inhale air. On the other hand, the air inlet of the one-way valve 11 is smaller than the aperture of the air inlet, and the air flow rate is fast. The gas during the intake can impact the objects and blow them off, thereby restoring the air intake of the air inlet pipe. The one-way valve 11 replaces manual work to move the objects away, and the degree of automation is high. The present invention sets a bearing ring 12 and a telescopic member 13. When the one-way valve 11 is intaken, the bearing ring 12 can drive the telescopic member 13 to repeatedly extend and retract. The extended telescopic member 13 can further push down the objects blocking the air inlet, so that the air inlet can resume air intake.

[0043] refer to Figure 5 , 7 Or 8, in a specific embodiment, the bearing ring 12 includes an inner ring 122 and an outer ring 121 sleeved outside the inner ring 122, and the inner ring 122 can rotate around the axis. Balls are arranged between the inner ring 122 and the outer ring 121 to make the inner ring 122 easy to rotate.

[0044] A first protrusion 1221 is provided on the side surface of the inner ring 122 close to the telescopic member 13 , and the side surface is also in contact with one end of the telescopic member 13 . When the inner ring 122 rotates, the first protrusion 1221 can push out the telescopic member 13 .

[0045] In this embodiment, the first protrusion 1221 is provided. When the inner ring 122 rotates, the first protrusion 1221 can push out the telescopic member 13, so that the telescopic member 13 can push down the object blocking the air inlet. The number of the first protrusions 1221 is set to be multiple, so that when the telescopic member 13 contacts the first protrusions 1221, it is pushed out, and when the telescopic member 13 is between the first protrusions 1221, it will retract.

[0046] refer to Figure 8In a specific embodiment, the first protrusion 1221 is a right-angled triangle, so that the inner ring 122 rotates along an acute angle of the right triangle. The first protrusion 1221 in this embodiment is set to be a right-angled triangle in order to limit the rotation direction of the inner ring 122, that is, Figure 8 The inner ring 122 rotates in a counterclockwise direction to cooperate with the one-way valve 11. The gas blown out by the one-way valve 11 pushes the inner ring 122 to rotate, thereby preventing the inner ring 122 from reversing and affecting the rotation speed of the inner ring 122. Figure 8 It is only a schematic diagram of an embodiment of the present invention. According to actual needs, the first protrusion 1221 and the air outlet angle of the one-way valve 11 can be adjusted so that the inner ring 122 rotates clockwise to push out the telescopic member 13. At the same time, the inclination angle of the blade 124 is adjusted so that the inner ring 122 rotates counterclockwise through the blade 124 when air is taken in by the intake pipe.

[0047] refer to Figure 8 In a specific embodiment, a plurality of protrusions 1222 are provided on the outer wall of the inner ring 122. Nearly half of the width of the outer wall of the inner ring 122 is used to cooperate with the outer ring 121, and a ball is inserted between the two. The remaining part of the outer wall of the inner ring 122 is provided with protrusions 1222, which cooperate with the air intake of the one-way valve 11 to make the inner ring 122 rotate.

[0048] In this embodiment, the first protrusion 1221 and the protrusion piece 1222 are simultaneously provided on the inner ring 122 , so that the one-way valve 11 can inlet air and blow the protrusion piece 1222 to drive the inner ring 122 to rotate, and at the same time the first protrusion 1221 pushes out the telescopic member 13 .

[0049] refer to Figure 8 In a specific embodiment, a center ring 123 is provided at the center of the inner ring 122, and the inner ring 122 and the center ring 123 are arranged concentrically. A second protrusion 1231 is provided on the side of the center ring 123 close to the telescopic member 13, and the second protrusion 1231 is also a right-angled triangle. The outer wall of the center ring 123 is connected to the inner wall of the inner ring 122 through a plurality of inclined blades 124. The intake of the one-way valve 11 can push the inner ring 122 to rotate in a first direction, and the gas entering the intake pipe can push the inner ring 122 to rotate in a second direction through the blades 124; the first direction and the second direction are opposite. The first direction is clockwise, and the second direction is counterclockwise. Alternatively, the first direction is counterclockwise, and the second direction is clockwise.

[0050] In this embodiment, a second protrusion 1231 is provided so that a retractable member 13 can also be provided in the middle position, so that the obstruction can be pushed out and removed more easily to restore air intake in the air intake pipe. Figure 7 , 8For example, by setting the blade 124, the telescopic member 13 can be returned to its original position. The end of the telescopic member 13 close to the inner ring 122 is always in contact with the side of the inner ring 122. When the one-way valve 11 blows the inner ring 122 to rotate counterclockwise, the contact end of the telescopic member 13 may slide to the inclined surface of the first protrusion 1221, and the obstruction at the air inlet is pushed out, and the air inlet resumes air intake. At this time, the telescopic member 13 partially protrudes from the air inlet, which is easy to cause inconvenience. The air intake at the air inlet blows the blade 124, so that the blade 124 drives the inner ring 122 to rotate clockwise, and the contact end of the telescopic member 13 can be stuck at the right angle end of the first protrusion 1221, so that the telescopic rod 13 retracts and resets. The blade 124 in this embodiment has a small inclination angle, so that the blade 124 generates a small rotational force, because when the abutting end of the telescopic member 13 is stationary on the inclined surface of the first protrusion 1221, the elastic force of the telescopic member 13 will also have a force to rotate the inner ring 122 clockwise, so that the inner ring 122 has a tendency to rotate clockwise, and the blade 124 only plays a small auxiliary role. At the same time, the blade 124 generates a small rotational force when the angle is small, which can also prevent the generation of excessive rotational force and damage to the telescopic member 13.

[0051] refer to Figure 6 In a specific embodiment, the telescopic member 13 includes a rod body 131, a spring 132 and a hinged rod 133. The rod body 131 is hinged to one end of the hinged rod 133, and the other end of the hinged rod 133 can be hinged to the intake pipe; the spring 132 is sleeved on the outside of the rod body 131 to provide a retraction force to the rod body 131.

[0052] This embodiment can limit the movement direction of the telescopic rod 13 by setting the hinge rod 133, and also increase the telescopic stability of the telescopic rod 13. The rod body 131 at the edge is provided with a protrusion that can clamp the spring 132 to prevent the spring 132 from falling off. The two ends of the rod body 131 are rounded to reduce friction, especially the abutting end can slide smoothly on the surface of the first protrusion 1221.

[0053] refer to Figure 5 and Figure 6 In a specific embodiment, the ejection assembly further includes an outer frame 14 , which is arranged parallel to the bearing ring 12 ; a through hole 141 is provided on the outer frame 14 , one end of the telescopic member 13 is arranged in the through hole 141 , and the telescopic member 13 can extend from the through hole 141 .

[0054] The outer frame 14 in this embodiment is a circular outer frame with a cross connecting rod arranged inside. The outer frame 14 is provided with a through hole 141, so that the rod body 131 can pass through the through hole 141, and the non-contact end of the rod body 131 can be placed in the through hole 141, which increases the stability of the rod body 131 when it is extended and retracted. Figure 5 The through hole 141 in the middle of the outer frame 14 enables the rod body 131 to pass through the middle.

[0055] refer to Figures 1 to 4 The second aspect of the present invention protects an air intake pipe having the above-mentioned anti-blocking structure. The anti-blocking structure 1 is arranged at the inlet position of the air intake pipe 2. Among them, the one-way valve 11 is arranged on the side of the air intake pipe 2, and the ejection assembly is arranged inside the air intake pipe 2.

[0056] refer to Figure 1 Or 2, in a specific embodiment, the air inlet pipe 2 includes a pipe body 21, and a sieve plate 22 is provided at the air inlet end of the pipe body 21. The purpose of providing the sieve plate 22 is to prevent some impurities from entering and damaging the anti-blocking structure 1.

[0057] A third aspect of the present invention protects an air compressor having the above-mentioned anti-clogging structure or air intake pipe.

[0058] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
