Description

Technical Field

[0001] This utility model relates to the field of salt spray machine nozzle technology, specifically a salt spray machine nozzle with an anti-clogging structure. Background Technology

[0002] The nozzle of a salt spray tester is one of its key components, directly affecting the uniformity of the salt spray, particle size, and accuracy of the test results. According to patent application publication number CN106622815A, this invention discloses a salt spray tester nozzle, including a salt spray tube and an air tube. The nozzle further includes a first fixing member, a second fixing member, and a telescopic mechanism. One end of the salt spray tube passes through and is fixed to the first fixing member, and one end of the air tube passes through and is detachably fixed to the second fixing member. The liquid outlet direction of the salt spray tube and the air outlet direction of the air tube form an angle. One end of the telescopic mechanism is fixed to one side of the first fixing member, and the other end of the telescopic mechanism is fixed to one side of the second fixing member.

[0003] However, existing salt spray nozzles require uniform spraying of salt water during use. After spraying, salt water residue easily remains inside the nozzle. As the water inside the nozzle evaporates, the salt crystallizes, which can clog the nozzle and affect its normal operation. Furthermore, pressure changes occur between the connecting pipe and the nozzle during spraying, and increased pressure can lead to leaks at the connection point. Therefore, improvements to the existing technology are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a salt spray nozzle with an anti-clogging structure, which solves the problems of nozzle clogging caused by salt crystallization and leakage at the connection point caused by high pressure after salt water injection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a salt spray nozzle with an anti-clogging structure, comprising a nozzle, a connecting pipe connected to the upper end of the nozzle via a thread, an inflation ring fixedly connected to the upper part of the inner wall of the nozzle, a thickened layer provided on the inner wall of the inflation ring, an inflation / deflation mechanism provided inside the nozzle, two symmetrically distributed fixing frames fixedly connected to the middle of the inner wall of the nozzle, a waterproof cover fixedly connected inside the two fixing frames, a movable plate slidably connected inside the waterproof cover, a rotating shaft mounted on the center of the movable plate via a bearing, a reamer fixedly connected to the lower outer side of the rotating shaft, an internally threaded pipe mounted inside the movable plate via a bearing, a screw fixedly connected inside the waterproof cover, a motor fixedly mounted on the upper end of the movable plate, and a gear fixedly connected to the outer side of the internally threaded pipe.

[0006] Preferably, a sealing tube is fixedly connected to the lower end of the waterproof cover, and the sealing tube is movably connected to the rotating shaft. The sealing tube can seal the connection between the rotating shaft and the waterproof cover.

[0007] Preferably, the screw is connected to the internally threaded tube by a thread, and the output shaft of the motor is fixedly connected to the rotating shaft, so that the motor can drive the rotating shaft to rotate.

[0008] Preferably, a second gear is fixedly connected to the outer side of the rotating shaft, and the second gear meshes with the first gear, so that the second gear can drive the first gear to rotate.

[0009] Preferably, the inflation / deflation mechanism includes an air pipe, the air pipe is fixedly connected inside the nozzle, a fixing plate is fixedly connected inside the air pipe, a guide rod is slidably connected inside the fixing plate, a ball plug is fixedly connected to one end of the guide rod, and a spring is provided on the outside of the guide rod, which can guide the movement of the ball plug.

[0010] Preferably, the air tube is fixedly connected to the inflation ring, and the ball plug is in sliding contact with the air tube, so that the ball plug can seal the air tube.

[0011] Preferably, one end of the spring is fixedly connected to the ball plug, and the other end of the spring is fixedly connected to the fixing plate. The spring can support the ball plug through its elastic force.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adds a waterproof cover, a reamer, and a screw inside the nozzle. When the nozzle is clogged, the motor drives the reamer on the outside of the shaft to rotate, and the gear set drives the internal threaded tube to rotate. The reamer moves downward while rotating, and the nozzle can be cleared by rotating the feed reamer, which can effectively prevent nozzle clogging.

[0014] 2. This utility model adds an inflation ring, an air pipe, and a sealing plug to the nozzle. After the connecting pipe is connected to the nozzle, air can be injected into the inside of the inflation ring through the air pipe, which increases the pressure inside the inflation ring. The increased pressure inside the inflation ring can increase the wrapping force of the inflation ring on the connecting pipe through the deformation of the inflation ring, thereby effectively improving the sealing performance and preventing leakage.

[0021] Please see Figure 1 , Figure 2 , Figure 3 A salt spray nozzle with an anti-clogging structure includes a nozzle 1. The upper end of the nozzle 1 is connected to a connecting pipe 2 via a thread. An inflation ring 3 is fixedly connected to the upper part of the inner wall of the nozzle 1. The inner wall of the inflation ring 3 is provided with a thickened layer 4. An inflation / deflation mechanism 5 is provided inside the nozzle 1. Two symmetrically distributed fixing frames 6 are fixedly connected to the middle of the inner wall of the nozzle 1. A waterproof cover 7 is fixedly connected to the inside of the two fixing frames 6. A movable plate 8 is slidably connected inside the waterproof cover 7. A rotating shaft 9 is installed at the center of the movable plate 8 via a bearing. A reamer 10 is fixedly connected to the lower outer side of the rotating shaft 9. An internally threaded pipe 12 is installed inside the movable plate 8 via a bearing. A screw 13 is fixedly connected inside the waterproof cover 7. A motor 16 is fixedly installed at the upper end of the movable plate 8. A gear 14 is fixedly connected to the outer side of the internally threaded pipe 12.

[0022] Please see Figure 1 , Figure 2 , Figure 3A sealing tube 11 is fixedly connected to the lower end of the waterproof cover 7. The sealing tube 11 is movably connected to the rotating shaft 9. The sealing tube 11 can seal the connection between the rotating shaft 9 and the waterproof cover 7. The screw 13 is connected to the internal threaded tube 12 by threads. The output shaft of the motor 16 is fixedly connected to the rotating shaft 9. The motor 16 can drive the rotating shaft 9 to rotate. A gear 2 15 is fixedly connected to the outside of the rotating shaft 9. The gear 2 15 meshes with the gear 1 14. The gear 2 15 can drive the gear 1 14 to rotate.

[0023] Please see Figure 1 , Figure 2 , Figure 4 The inflation / deflation mechanism 5 includes an air pipe 51. The air pipe 51 is fixedly connected inside the nozzle 1. A fixing plate 52 is fixedly connected inside the air pipe 51. A guide rod 53 is slidably connected inside the fixing plate 52. A ball plug 54 is fixedly connected to one end of the guide rod 53. A spring 55 is provided on the outside of the guide rod 53. The guide rod 53 can guide the movement of the ball plug 54. The air pipe 51 is fixedly connected to the inflation ring 3. The ball plug 54 slides in contact with the air pipe 51 and can seal the air pipe 51. One end of the spring 55 is fixedly connected to the ball plug 54, and the other end of the spring 55 is fixedly connected to the fixing plate 52. The spring 55 can support the ball plug 54 with its elastic force.

[0024] The specific implementation process of this utility model is as follows: After the connecting pipe 2 is installed inside the nozzle 1, the air pump pipeline is connected to the air pipe 51, and then the air pump is used to inflate the air pipe 51. When the thrust generated by the inflated air pressure is greater than the thrust of the spring 55 on the ball plug 54, the ball plug 54 moves. When the ball plug 54 is separated from the air pipe 51, the air pipe 51 can be used to inflate the air ring 3. After the air ring 3 is inflated, it expands, which increases the adhesion of the connecting pipe 2, thereby avoiding the leakage caused by excessive pressure inside the nozzle 1.

[0025] When nozzle 1 needs cleaning, motor 16 is started. Motor 16 drives shaft 9 to rotate. During the rotation of shaft 9, reamer 10 rotates. At the same time, shaft 9 drives gear 2 15 to rotate. Gear 2 15 drives internal thread tube 12 to rotate through gear 1 14. During the rotation of internal thread tube 12, the threaded engagement between internal thread tube 12 and screw 13 drives moving plate 8 to move. During the movement of moving plate 8, reamer 10 moves while rotating through shaft 9. Thus, nozzle 1 can be unblocked by rotating reamer 10, which can effectively prevent nozzle 1 from becoming clogged.
