Air amplifier for welding module

Abstract

The utility model provides an air amplifier for a welding module. The air inlet cavity is defined by the radial outer surface of the first sleeve body section, the end face of the second sleeve body section, the radial inner surface of the first sleeve body section and the first matching part, and communication between the air inlet cavity and the inner cavity is achieved through the vent groove in the end face of the first sleeve body section. Therefore, dust is effectively prevented from entering the air inlet cavity and the compressed air inlet through the vent groove. Besides, the air inlet side of the first matching part is a guide cambered surface, and the middle part of the guide cambered surface protrudes towards the radial inner side of the first sleeve body, so that when air enters the first sleeve, dust carried in the air flow can impact the protruding part of the guide cambered surface, and the dust is effectively prevented from entering the first sleeve. Through the arrangement, dust falling into the amplifier can be effectively reduced, and the cleaning period is prolonged.

[0026] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0027] like Figure 1 and Figure 2As shown, an embodiment of the present disclosure provides an air amplifier for a welding module, which includes a first sleeve 10 and a second sleeve 20 that cooperate with each other. The first sleeve 10 includes a first sleeve body 11, a compressed gas inlet 111 is provided on the side wall of the first sleeve body 11, and an annular first matching portion 12 is protruded on the radial inner surface of the air inlet end of the first sleeve body 11. The axis of the first matching portion 12 coincides with the axis of the first sleeve body 11. The air inlet side of the first matching portion 12 includes a guide arc surface 121, and the middle portion of the guide arc surface 121 protrudes toward the radial inner side of the first sleeve body 11.

[0028] The second sleeve 20 includes a second sleeve body, and the second sleeve body includes a first sleeve body section 21 and a second sleeve body section 22 connected to each other. The outer diameter of the first sleeve body section 21 is smaller than the outer diameter of the second sleeve body section 22. The second sleeve body section 22 cooperates with the inner hole of the first sleeve body 11. One end of the first sleeve body section 21 abuts against the first matching portion 12, and the other end of the first sleeve body section 21 is connected to the second sleeve body section 22. The radial outer surface, the end face of the second sleeve body section 22, the radial inner surface of the first sleeve body 11, and the first fitting portion 12 together form an air intake chamber 23, and the compressed gas inlet 111 is connected to the air intake chamber 23. A plurality of ventilation grooves 211 are circumferentially arranged on the end face of the first sleeve body section 21 abutting against the first fitting portion 12. The ventilation grooves 211 connect the air intake chamber 23 and the inner cavity of the second sleeve 20, and the axial size of the ventilation grooves 211 first decreases and then increases in the radial direction.

[0029] In the air amplifier for a welding module provided in this embodiment, an air inlet chamber 23 is formed by the radial outer surface of the first sleeve body section 21, the end surface of the second sleeve body section 22, the radial inner surface of the first sleeve body 11, and the first mating portion 12. The air inlet chamber 23 is connected to the inner chamber via a vent groove 211 on the end surface of the first sleeve body section 21. Because the compressed gas flow path is circuitous, dust is effectively prevented from entering the air inlet chamber 23 and the compressed gas inlet through the vent groove 211. Furthermore, the air inlet side of the first mating portion 12 is a guide arc surface 121, the middle portion of which protrudes radially inwardly of the first sleeve body 11. Thus, when air is introduced into the first sleeve 10, dust carried in the airflow will collide with the protruding portion of the guide arc surface 121, thereby effectively preventing dust from entering the amplifier. This arrangement effectively reduces dust from entering the amplifier, extending the cleaning cycle.

[0030] In one embodiment, the inner diameters of the first sleeve body section 21 and the second sleeve body section 22 are the same, so that the inner walls of the first sleeve body section 21 and the second sleeve body section 22 are smoothly connected, which can reduce wind resistance and avoid the generation of sanitary dead corners.

[0031] In one embodiment, an annular groove 112 is provided on the radial inner surface of the side wall of the first sleeve body 11, and the compressed gas inlet is connected to the annular groove 112. In this way, on the one hand, the setting of the annular groove 112 can enable the air inlet cavity 23 to intake air evenly in the circumferential direction, thereby improving the air outlet efficiency of the air amplifier. On the other hand, the bottom of the annular groove 112 can limit the compressed gas delivery pipe of the compressed gas inlet 111.

[0032] In one embodiment, a second fitting portion 221 is provided on the radial outer surface of the second sleeve body section 22 , and the second fitting portion 221 is fixedly connected to the first sleeve body 11 .

[0033] In one embodiment, the second matching portion 221 is an annular protruding structure, the second matching portion 221 abuts against the end face of the first sleeve body 11, a plurality of first connecting holes are provided on the second matching portion 221, and second connecting holes corresponding one-to-one to the plurality of first connecting holes are provided on the end face of the first sleeve body 11 facing the second matching portion 221, and the first connecting hole and the second connecting hole are fixedly connected by a fastener 30.

[0034] In one embodiment, the outer diameter of the second matching portion 221 is the same as the outer diameter of the first sleeve body 11 , thereby ensuring that the appearance of the air amplifier is smooth and avoiding sanitary dead corners.

[0035] In one embodiment, a sealing ring 40 is provided between the second fitting portion 221 and the first sleeve body 11 , thereby ensuring sealing between the second fitting portion 221 and the first sleeve body 11 and preventing air leakage.

[0036] In one embodiment, the end face of the first sleeve body 11 is provided with a receiving groove, and the sealing ring 40 is arranged in the receiving groove, so that the sealing ring 40 is in contact with the end face of the second matching portion 221 and the radial outer surface of the second sleeve body section 22 at the same time, thereby further improving the sealing performance.

[0037] In one embodiment, if Figure 3As shown, a first super-hydrophobic coating 51 is provided on the radial inner surface of the first fitting portion 12 facing the first sleeve body 11; a second super-hydrophobic coating 52 is provided on the bottom surface of the ventilation groove 211; a third super-hydrophobic coating 53 is provided on the radial inner surface of the first sleeve body section 21; and a fourth super-hydrophobic coating 54 is provided on the radial inner surface of the second sleeve body section 22, thereby effectively reducing the accumulation of dust on various wall surfaces inside the air amplifier.

[0038] In one embodiment, the second super-hydrophobic coating 52 , the third super-hydrophobic coating 53 and the fourth super-hydrophobic coating 54 are an integrated structure, thereby facilitating processing.

[0039] In the air amplifier for a welding module provided in this embodiment, an air inlet chamber 23 is formed by the radial outer surface of the first sleeve body section 21, the end surface of the second sleeve body section 22, the radial inner surface of the first sleeve body 11, and the first mating portion 12. The air inlet chamber 23 is connected to the inner chamber via a vent groove 211 on the end surface of the first sleeve body section 21. Because the compressed gas flow path is circuitous, dust is effectively prevented from entering the air inlet chamber 23 and the compressed gas inlet through the vent groove 211. Furthermore, the air inlet side of the first mating portion 12 is a guide arc surface 121, the middle portion of which protrudes radially inwardly of the first sleeve body 11. Thus, when air is introduced into the first sleeve 10, dust carried in the airflow will collide with the protruding portion of the guide arc surface 121, thereby effectively preventing dust from entering the amplifier. This arrangement effectively reduces dust from entering the amplifier, extending the cleaning cycle.

[0040] The above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the scope of patent protection of the present invention shall be defined by the claims.
