Description

Technical Field

[0001] The invention relates to a three-stage vacuum generator with vortex airflow and multi-stage suction holes. Background Art

[0002] Generally, the vacuum generators currently used have multiple gas suction holes inside, which usually adopt the design of left and right holes. Therefore, when the gas is guided, the size and design of the gas suction holes may limit the ability of the gas to flow, and the smaller aperture or narrow channel may produce a bottleneck effect of the airflow, restricting the smooth flow of the gas and causing the airflow speed to decrease, thereby affecting the working efficiency and speed of the vacuum generator.

[0003] Furthermore, because the airflow is restricted, pressure loss may occur when the gas passes through the internal gas intake hole, and such pressure loss may also cause the gas outflow pressure to be lower than the required value, thereby affecting the performance of the vacuum system.

[0004] The above-mentioned restrictions on the gas suction hole may also limit the maximum power of the vacuum generator. If the gas cannot pass through the aperture or channel to provide sufficient gas flow, the vacuum generator may not be able to achieve the required vacuum degree or the ability to handle large workpieces. Since the internal gas suction hole is in contact with the environment, there is a certain risk that it may be blocked by dust, pollutants or other foreign matter. These obstructions may limit the passage of gas, further reduce the efficiency of the vacuum generator, and even cause system failure.

[0005] Therefore, the inventors have found out through practical application and research that the above-mentioned existing structure still has shortcomings that need to be improved. Summary of the invention

[0006] In view of the complicated steps of today's industrial processing, the requirements for precision control are becoming more and more stringent, so the ability to increase fluid throughput and stabilize output rate is an area that urgently needs to be improved.

[0007] In order to achieve the above objectives, the main purpose of the present invention is to provide a three-stage vacuum generator with vortex airflow and multi-stage suction holes, wherein a first vacuum tube, a second vacuum tube and a third vacuum tube are sequentially arranged inside the main body.

[0008] A vortex nozzle is arranged at the front end of the body and fixedly connected to the body to increase the fluid flow rate. The body is also provided with a plurality of multi-stage suction holes at a certain interval on the side edge. The first stage vacuum tube and the body are integrated into one design, and the second stage vacuum tube is connected to the third stage vacuum tube and the first stage vacuum tube in sequence to form a vacuum tube assembly to increase the fluid suction amount through the multi-stage suction holes.

[0009] The third section of the vacuum tube further comprises: a pair of protrusions symmetrically arranged at the outer edge of the third vacuum tube, and a pair of positioning protrusions are arranged near the end of the protrusion.

[0010] The protrusion and the positioning protrusion are arranged non-parallel.

[0011] The invention also comprises: a shell body, which can provide an internal space in which at least one of the main bodies is arranged.

[0012] It also includes: a positioning groove for connecting with the cam.

[0013] It also includes: a positioning groove, which is used to connect with the positioning protrusion.

[0014] It also includes: the multi-stage suction hole is four holes, and is arranged in a symmetrical manner, so that the multi-stage suction hole can be further combined with the vacuum tube assembly to further increase the suction volume of the fluid.

[0015] The invention also comprises: the size of the vortex nozzle piece is smaller than the inner wall of the front end of the body and the whole is cylindrical; the inner wall of one end of the vortex nozzle piece is sunken toward the central axis to be in a funnel shape.

[0016] The vortex nozzle component also includes: a first vortex, which is arranged at one end of the vortex nozzle component; a second vortex, which is relatively arranged at the other end of the vortex nozzle component, and the blades of the first vortex and the second vortex are designed to be clockwise and counterclockwise, which can increase the flow rate of the external fluid when passing through, so as to cooperate with the subsequent operation of the vacuum tube assembly.

[0017] The three-stage vacuum generator of the present invention has a vortex nozzle and a multi-stage vacuum tube design inside its body, which is further matched with the multi-stage suction holes provided in the body, so that the fluid suction volume can be effectively increased, and the vacuum tube can also be connected in sections, so that the subsequent maintenance work steps are simplified and convenient.

[0047] Generally, according to the best possible embodiment of the present invention, and in conjunction with Figures 1 to 12 After the detailed description, the understanding of the present invention is increased. The present invention is a three-stage vacuum generator with a vortex airflow and a multi-stage suction hole. The three-stage vacuum generator has a main body 10, and the main body 10 is provided with a front end 101 and a rear end 102, and the interior of the main body 10 is sequentially provided with: a first-stage vacuum tube 11, a second-stage vacuum tube 12 and a third-stage vacuum tube 13.

[0048] A vortex nozzle 30 is used to increase the fluid flow rate. The vortex nozzle 30 is arranged at the front end 101 and connected to the body 10, and a plurality of multi-stage suction holes 20 are arranged at a certain interval on the side edge of the body 10, wherein the first stage vacuum tube 11 and the body 10 are integrated, and the second stage vacuum tube 12, the third stage vacuum tube 13 and the first stage vacuum tube 11 are connected in sequence to form a vacuum tube assembly 14, so as to increase the fluid suction amount through the multi-stage suction holes 20. The multi-stage suction holes 20 can be referred to Figure 7 In the present invention, there are 4 in each layer, 3 layers in total, and 12 in total, which can effectively improve the fluid intake.

[0049] The overall size of the vortex nozzle 30 is smaller than the inner wall of the front end 101 of the body 10, and its overall shape is roughly cylindrical, and the inner wall of one end of the vortex nozzle 30 is sunken toward the central axis to form a funnel shape. The vortex nozzle 30 also includes: a first vortex 31, which is arranged at one end of the vortex nozzle 30; a second vortex 32, which is arranged at the other end of the vortex nozzle 30, and the blades of the first vortex 31 and the second vortex 32 are designed to be clockwise and counterclockwise. This part can be referred to Fig. 9 and Fig.11 Of course, if the first vortex 31 and the second vortex 32 are changed to clockwise, counterclockwise, or counterclockwise, it is also a common change method in this field, so it will not be repeated. Fig.12 As shown, it can be seen that the first vortex 31 and the second vortex 32 are connected to each other, which can increase the flow rate of the external fluid when passing through, so as to cooperate with the subsequent operation of the vacuum tube assembly 14.

[0050] The third section of the vacuum tube 13 further comprises: a pair of protrusions 131, the pair of protrusions 131 are symmetrically arranged at the outer edge of the third section of the vacuum tube 13, and the protrusions 131 are also arranged with a pair of positioning protrusions 132 near the end 102, and the protrusions 131 and the positioning protrusions 132 are non-parallel. The non-parallel arrangement here means that the protrusions 131 and the positioning protrusions 132 are not in the same plane, and the two points extend horizontally and do not intersect.

[0051] A housing 40, whose internal space can accommodate at least one of the main bodies 10, and the housing 40 can also be expanded with additional related components. A positioning groove 41 is also provided inside the housing 40, and the positioning groove 41 is mainly used to connect and fix with the cam. Another positioning groove 42 is provided near the positioning groove 41, and the positioning groove 42 is mainly used to connect and fix with the positioning protrusion 132. Through the cam 131 and the positioning protrusion 132, the main body 10 can be fixed by two means, and the connection with the housing 40 is further strengthened.

[0052] The present invention has a three-stage vacuum generator with a vortex airflow and a multi-stage suction hole. The vortex nozzle member 30 is mainly designed to be disposed at the front end 101 of the body 10 to increase the fluid suction amount. The front end of the body 10 is integrated with the first section vacuum tube 11, which can effectively reduce the complexity of parts and increase the service life. After the second section vacuum tube 12 and the third section vacuum tube 13 are connected to the first section vacuum tube 11, they are further disposed in the body 10 to form a vacuum tube assembly 14, which cooperates with the side of the body 10. A plurality of multi-stage suction holes 20 are arranged at a certain interval on the edge. The multi-stage suction holes 20 are four holes and are arranged in a symmetrical manner. The multi-stage suction holes 20 can further cooperate with the vacuum tube assembly 14 to further increase the amount of fluid suction. The third stage vacuum tube 13 also has the convex catch 131 and the positioning protrusion 132, which can allow the main body 10 and the vacuum tube assembly 14 to utilize the non-parallel arrangement of the convex catch 131 and the positioning protrusion 132, so that at least one or more main bodies 10 can be accommodated in a shell 40, thereby forming a high-efficiency vacuum generator.
