[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0049] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0050] As Figures 1 - 4 shown, the present invention provides a nozzle welding method, which includes:

[0051] Step 1: Configure the fixture 3 on the welding device 4;

[0052] Step 2: Configure the nozzle 100 to be welded on the fixture 3, so that the first welding position of the nozzle 100 is located at the welding station;

[0053] Step 3: Start the welding device 4 to weld the first welding position 100a;

[0054] Step 4: After the welding device 4 resets, operate the fixture 3 again, so that the second welding position 100b of the nozzle 100 is located at the welding station;

[0055] Step 5: Start the welding device 4 to weld the second welding position 100b;

[0056] Step 6: Remove the welded nozzle 100 from the fixture 3, and then configure the nozzle 100 to be welded.

[0057] Among them, through the step design of the above method, the welding method is suitable for the production of small-scale and customized nozzles, and the welding method can be used to weld two different positions of the nozzle, greatly improving the production efficiency. Moreover, compared with the threaded connection, the welding method can improve the sealing performance of the nozzle and prevent liquid leakage.

[0058] Exemplary welding device

[0059] As Figures 2 - 3 shown, further, in some embodiments of the present invention, the welding device 4 is set as an ultrasonic welding machine. Here, the ultrasonic welding machine is used to weld the first welding position and the second welding position of the nozzle 100 (mainly made of plastic). It should be noted that the nozzle 100 is mainly made of plastic, and the first welding position and the second welding position are also welds on plastic parts. Therefore, ultrasonic welding is used to improve the sealing performance of the nozzle and prevent liquid leakage.

[0060] Specifically, the welding device 4 with the above structure includes a welding machine base 41, a welding lifting frame 42, and an ultrasonic welding head module 43. The welding lifting frame 42 is installed on the welding machine base 41, and the ultrasonic welding head module 43 is installed on the welding lifting frame 42. Here, in order to facilitate the operator to operate the welding device 4, an operation switch can be installed on the welding machine base 41. Pressing the operation switch can realize the up and down movement of the ultrasonic welding head module 43, and the welding lifting frame 42 is used to drive the ultrasonic welding head module 43 to move up and down to weld the nozzle 100;

[0061] The above-mentioned fixture 3 is installed on the welding machine base 41. Here, the fixture 3 is located below the ultrasonic welding head module 43. The fixture 3 drives the nozzle 100 to rotate, so that the first welding position on the nozzle 100 is first located below the ultrasonic welding head module 43, and then the second welding position is located below the ultrasonic welding head module 43 after rotation, thus facilitating the continuous welding of the nozzle 100 without the operator manually changing the position of the nozzle 100 to change the first welding position and the second welding position.

[0062] Exemplary fixture

[0063] As Figures 3 - 4As shown in the figure, further, in some embodiments of the present invention, the specific structure of the above-mentioned fixture 3 is provided. Here, the fixture 3 of this structure includes a first clamp body 31, a second clamp body 32, a first motor 33, and two second motors 34. Among them, the first clamp body 31 and the second clamp body 32 are installed on the welding base 41, and a clamp plate 35 is rotatably installed between the first clamp body 31 and the second clamp body 32. The above-mentioned first motor 33 is installed on one side of the first clamp body 31 and is rotatably connected to the clamp plate 35. A fixed clamp arm 351 and a movable clamp arm 352 are respectively installed on the clamp plate 35, and the two second motors 34 are installed at the bottom of the clamp plate 35 and are respectively connected to the movable clamp arm 352. Therefore, the second motor 34 can be started through a fixture controller (not shown), and the movable clamp arm 352 is driven by the second motor 34 to approach or move away from the fixed clamp arm 351, so as to realize the clamping and fixing or loosening of the nozzle 100 by the fixed clamp arm 351 and the movable clamp arm 352; the first motor 33 can drive the clamp plate 35 to rotate by 90°, so as to realize the rotation of the first welding position of the nozzle 100 to the second welding position and improve the welding efficiency.

[0064] Furthermore, in some embodiments of the present invention, two guide grooves 3 are opened on the clamp plate 35, and guide rods 354 are installed in the guide grooves 3. Furthermore, the bottom of the movable clamp arm 352 has a guide plate 355 corresponding to the guide rods 354. Here, the guide plate 355 is slidably connected in the guide grooves 3, and the guide rods 354 provide a guiding effect for the guide plate 355. Moreover, the guide plate 355 is movably connected to the second motor 34. Therefore, when the second motor 34 is started, it can drive the guide plate 355 to move along the guide rods 354, and then the movable clamp arm 352 can approach or move away from the fixed clamp arm 351, so as to facilitate the fixing or loosening of the nozzle 100 and improve the working efficiency of the operator.

[0065] Furthermore, a transverse lead screw 341 is installed on the motor shaft of the second motor 34, a lead screw block 342 is installed on the transverse lead screw 341, and the lead screw block 342 is connected to the guide plate 355. Here, the transverse lead screw 341 and the lead screw block 342 can drive the movement of the guide plate 355, and then realize the movement of the movable clamp arm 352.

[0066] Exemplary ultrasonic welding head module

[0067] Such as Figures 5 - 16As shown, further, in some embodiments of the present invention, the specific structure of the above ultrasonic welding head module 43 is provided. Here, the ultrasonic welding head module 43 includes a welding head body 44, a welding head rod 45, and a welding head seat 46. It can be understood that the welding head body 44 is installed on the welding lifting frame 42, and a starting device (not shown) for generating ultrasonic welding is provided inside the welding head body 44. The welding head seat 46 is installed at the bottom of the welding head body 44, and the welding head rod 45 is installed at the bottom of the welding head seat 46. The welding head body 44 performs ultrasonic welding actions on the welding head seat 46, and then ultrasonic welding is performed on the first welding position 100a and the second welding position 100b respectively through the welding head rod 45. Moreover, when the welding head rod 45 is worn, it can be conveniently replaced from the welding head seat 46, improving production efficiency.

[0068] As Figure 6 shown, further, in some embodiments of the present invention, an internal connection groove 461 is provided in the welding head seat 46, a rod cap 462 is installed in the internal connection groove 461, and a locking mechanism 47 is also installed at the bottom of the welding head seat 46. The upper end of the above welding head rod 45 passes through the locking mechanism 47 and extends into the rod cap 462. A clamping groove 451 is provided at the upper end of the welding head rod 45, and a clamping block 463 corresponding to the clamping groove 451 is provided inside the rod cap 462. The welding head rod 45 can be preliminarily fixed by the rod cap 462, and the locking mechanism 47 further strengthens the welding head rod 45, and it is also convenient to release the fixation of the welding head rod 45, improving the efficiency of replacing the welding head rod 45.

[0069] Exemplary locking mechanism

[0070] As Figures 6 - 10As shown in the figure, further, in some embodiments of the present invention, the specific structure of the above-mentioned locking mechanism 47 is provided. Here, the locking mechanism 47 of this structure includes an outer support ring 48, an outer retaining disk 49, and two inner locking members 50. Among them, the outer support ring 48 is installed at the bottom of the welding head base 46, and the outer retaining disk 49 is rotatably installed at the bottom of the outer support ring 48. There are two locking guide grooves 491 on the outer retaining disk 49. The two inner locking members 50 are symmetrically installed inside the outer support ring 48. Here, the inner locking member 50 of this structure includes an inner guide rod 501 and a C-shaped clamping plate 502. The inner guide rod 501 slidably passes through the guide hole 480 of the outer support ring 48. The C-shaped clamping plate 502 is installed at the inner end of the inner guide rod 501, and there is a T-shaped guide post 503 on the inner guide rod 501 corresponding to the locking guide groove 491. The welding head rod body 45 passes through between the two C-shaped clamping plates 502. Therefore, by rotating the outer retaining disk 49, the locking guide groove 491 drives the inner guide rod 501 to move towards the welding head rod body 45, so that the two C-shaped clamping plates 502 tightly fix the welding head rod body 45; conversely, the two C-shaped clamping plates 502 can be loosened from the welding head rod body 45, facilitating the removal of the welding head rod body 45 from the welding head base 46 and the locking mechanism 47 for replacement.

[0071] As Figures 9 - 10 shown, further, side shielding blocks 504 are respectively installed on both sides of the C-shaped clamping plate 502, and a shielding body 505 is installed between the inner guide rod 501 and the two side shielding blocks 504. There are a plurality of buckling grooves 506 on the inner wall of the side shielding block 504, so that the adjacent two side shielding blocks 504 are buckled and connected. Therefore, when the two C-shaped clamping plates 502 are buckled and fixed to the welding head rod body 45, the adjacent two side shielding blocks 504 also approach and are buckled and connected. In this way, the shielding body 505 shields between the outer support ring 48 and the outer retaining disk 49, preventing external dust, water vapor, etc. from entering the outer support ring 48, preventing the components inside the outer support ring 48 from rusting, and also preventing the welding head rod body 45 from rusting.

[0072] Exemplary limiting mechanism

[0073] As Figure 11 shown, further, in some embodiments of the present invention, a limiting mechanism 51 corresponding to the outer retaining disk 49 is also installed at the bottom of the welding head base 46. The limiting mechanism 51 prevents the outer retaining disk 49 from undergoing circumferential displacement, causing the loosening of the welding head rod body 45 and affecting the ultrasonic welding quality.

[0074] Specifically, the limiting mechanism 51 of this structure includes a limiting cap 52, an inner spring telescopic member (not shown), and a limiting block 54. Among them, the limiting cap 52 is located on one side of Chen, and the inner spring telescopic member is installed inside the limiting cap 52. The limiting block 54 is connected to the inner spring telescopic member through a support rod 541. The inner spring telescopic member provides elastic support for the limiting block 54 inside the limiting cap 52. Further, there are two first limiting bodies 542 on the limiting block 54. Correspondingly, there are multiple second limiting bodies 492 on the outer retaining disc 49 that engage with the first limiting bodies 542. In this way, the outer retaining disc 49 can be limited by the limiting block 54 to prevent it from undergoing circumferential displacement. When it is necessary to release the outer retaining disc 49, the limiting block 54 can be pressed upward. In this way, the limiting block 54 drives the support rod 541 to move inside the limiting cap 52, and then the inner spring telescopic member contracts to release the limiting block 54 and the outer retaining disc 49. The above process is simple to operate and highly efficient.

[0075] Exemplary anti-rust mechanism

[0076] As Figures 12 - 13 shown, further, in some embodiments of the present invention, there is also an anti-rust mechanism 55. Here, the anti-rust mechanism 55 is installed in the outer support ring 48 to adsorb the water vapor entering the outer support ring 48 and prevent other components from rusting.

[0077] Specifically, the anti-rust mechanism 55 of this structure includes an inner connecting rod 551, an anti-rust outer seat 552, and an anti-rust inner seat 553. Among them, the inner connecting rod 551 is installed on the inner guide rod 501, and the anti-rust outer seat 552 is installed on the inner connecting rod 551. The anti-rust inner seat 553 is slidably installed inside the anti-rust outer seat 552. An activated carbon bag (not shown) is placed in the anti-rust inner seat 553. A pull cap block 554 is provided at the outer end of the anti-rust inner seat 553. A moving groove 481 corresponding to the pull cap block 554 is opened on the outer support ring 48. Therefore, when replacing the welding head rod body 45, the outer retaining disc 49 is rotated so that the inner guide rod 501 moves outward along the guide hole 480. At the same time, the inner guide rod 501 drives the inner connecting rod 551 to also move outward. Then, the anti-rust outer seat 552 moves outward along the moving groove 481. Then, the operator can pull the pull cap block 554 outward to take out the anti-rust inner seat 553 from the anti-rust outer seat 552. Then, by opening the cap block 554, the activated carbon bag can be replaced, thereby greatly improving the service life of the components in the outer support ring 48.

[0078] Among them, a first magnet 556 is also installed at the bottom of the anti-rust inner seat 553, and a second magnet 557 is installed inside the anti-rust outer seat 552. In this way, the mutual magnetic attraction of the first magnet 556 and the second magnet 557 further increases the stability of the anti-rust inner seat 553 inside the anti-rust outer seat 552. The anti-rust inner seat 553 and the anti-rust outer seat 552 are provided with adsorption holes to facilitate the internal activated carbon bag to adsorb water vapor.

[0079] Furthermore, a first side groove 482 and a second side groove 483 are also formed in the outer support ring 48. The first side groove 482 is located at the end of the moving groove 481, and the second side groove 483 is located at the inner end of the first side groove 482. A side blocking body 484 is installed in the first side groove 482, and a side ejector rod 485 extending into the first side groove 482 is installed in the second side groove 483. The side ejector rod 485 is connected to the side blocking body 484. The part of the side ejector rod 485 located in the first side groove 482 has an inner spring 486. Therefore, when the inner spring 486 abuts against the side blocking body 484, the side blocking body 484 can enter the moving groove 481 to block the pull cap block 554, preventing the rust-proof inner seat 553 from sliding out of the rust-proof outer seat 552 during ultrasonic welding. An inner guiding layer 487 is also provided on the side blocking body 484, and a guiding bead 555 corresponding to the inner guiding layer 487 is provided on the pull cap block 554. Therefore, when the side blocking body 484 is moved to the first side groove 482, the sliding connection between the guiding bead 555 and the inner guiding layer 487 makes it easier for the operator to move the side blocking body 484. A side pulling plate 489 extending to the outer wall of the outer support ring 48 is provided on the side blocking body 484. Therefore, the side pulling plate 489 can drive the side blocking body 484 to move into the first side groove 482, so that the side pulling plate 489 no longer blocks the pull cap block 554, facilitating the subsequent removal of the pull cap block 554.

[0080] Exemplary outer support ring

[0081] As Figures 14 - 15 shown, further, in some embodiments of the present invention, two C-shaped cylinders 56 are also installed on the outer support ring 48. One ends of the two C-shaped cylinders 56 are connected to each other. A lock head 561 is installed at the other end of one C-shaped cylinder 56, and a lock core 562 is installed at the other end of the other C-shaped cylinder 56. A plurality of first lock teeth 563 are provided on the lock core 562, and second lock teeth 564 are provided in the lock head 561. Therefore, when the lock core 562 enters the lock head 561, the first lock teeth 563 on the lock core 562 abut against the second lock teeth 564, so that the two C-shaped cylinders 56 wrap the outer support ring 48 and can further block the side blocking body 484. Heat-conducting materials such as heat-conducting silicone grease can be filled in the C-shaped cylinder 56 to achieve the heat dissipation effect on the welding head rod body 45.

[0082] Further, a release plate 542 is mounted on the support rod 541, a release rod 543 is mounted on the release plate 542, and a release tooth 544 is provided on the release rod 543. Here, the release tooth 544 has a first inclined surface, and the first locking tooth 563 has a second inclined surface corresponding to the first inclined surface. Therefore, when replacing the welding head rod body 45, press the limit block 54 upward. The limit block 54 drives the support rod 541 to move, and then the support rod 541 drives the release plate 542 and the release rod 543 to move upward as well, so that the release tooth 544 abuts against the first locking tooth 563, and then the first locking tooth 563 is pushed out of the lock head 561 outward. In this way, the operator can pull the two C-shaped cylinders 56 apart, and then can remove the C-shaped cylinder 56 from the outer support ring 48. By rotating the outer retaining disc 49, the C-shaped fastener 502 and the rust-proof inner seat 553 can be opened. When removing the welding head rod body 45, it is also convenient to replace the activated carbon bag in the rust-proof inner seat 553, which facilitates the use of the ultrasonic welding head module 43.

[0083] As Figures 16 - 20 shown, the present invention also provides a nozzle 100, including: a nozzle 100. Here, the nozzle 100 includes a nozzle seat 1 and a nozzle cap 2. A first channel 101, a second channel 102 communicating with the first channel 101, a third channel 103 communicating with the second channel 102, and a fourth channel 104 communicating with the first channel 101 are formed in the nozzle seat 1. The nozzle cap 2 is rotatably mounted on the nozzle seat 1 through a fixed shaft 20, and the fixed shaft 20 extends to block the first channel 101, that is, the nozzle cap 2 rotates around the fixed shaft 20. The opening of the second channel 102 extends to the bottom of the nozzle seat 1, and a blocking body 121 is provided at the bottom of the second channel 102. Therefore, the bottom of the nozzle seat 1 has the blocking body 121 for blocking the second channel 102, and the high-pressure liquid leakage is prevented through the blocking body 121.

[0084] Therefore, when the nozzle 100 is connected to an external pipe during use, the high-pressure liquid flow in the external pipe enters the fourth channel 104, enters the first channel 101 through the fourth channel 104, then enters the second channel 102, and enters the third channel 103 through the second channel 102. Since the nozzle cap 2 has a first nozzle cap 21 and a second nozzle cap 22 corresponding to the third channel 103, and the nozzle cap 2 is also rotatably connected to the nozzle seat 1, by rotating the nozzle cap 2, when the first nozzle cap 21 corresponds to the third channel 103, a first-shaped spray can be ejected outward; when the second nozzle cap 22 corresponds to the third channel 103, a second-shaped spray can be ejected outward.

[0085] Among them, the first welding position 100a is where the fixed shaft 20 is located below the ultrasonic welding head module 43, and the second welding position 100b is where the plugging body 121 is located below the ultrasonic welding head module 43. Therefore, the fixed shaft 20 and the plugging body 121 are installed by the above-mentioned nozzle welding method, so that the fixed shaft 20 and the plugging body 121 are fixedly installed on the nozzle seat 1. Moreover, compared with using threaded connection, the welding method can improve the sealing performance of the nozzle and prevent liquid leakage.

[0086] After the nozzle 100 is ultrasonically welded, it can be easily adjusted. It is not only used for ordinary liquid spraying, but also for disinfectant spraying, and can also be used on vacuum cleaner equipment. By rotating to adjust different nozzles, spraying can be carried out for different environments, and the spraying method can be conveniently installed and replaced, with good versatility.

[0087] It can be understood that those skilled in the art can also set a third nozzle cap, a fourth nozzle cap, and even more nozzle caps on the nozzle cover 2 to meet the spraying needs of more scenarios, and the present invention will not list them one by one here.

[0088] Exemplary nozzle seat

[0089] As Figures 16 - 20 shown, further, in some embodiments of the present invention, the specific structure of the above-mentioned nozzle seat 1 is provided. Here, the nozzle seat 1 of this structure includes a seat plate 11, a seat body 12, and a tail rod 13. Among them, the seat plate 11 is installed at the front of the seat body 12, and the tail rod 13 is installed at the rear of the seat body 12. Of course, the above three can be integrally formed by injection molding; the first channel 101 and the third channel 103 are respectively arranged in the seat plate 11 and the seat body 12, the second channel 102 is opened in the seat body 12 and is located between the first channel 101 and the third channel 103, and the fourth channel 104 is arranged in the tail rod 13.

[0090] Due to manufacturing process reasons, the opening of the second channel 102 will extend to the bottom of the seat body 12. Therefore, the bottom of the seat body 12 has a plugging body 121 for plugging the second channel 102 to prevent high-pressure liquid from leaking;

[0091] Furthermore, an outwardly convex decorative seat 200 can be configured on the front wall of the nozzle cover 2, and the first mounting hole 200a, the second mounting hole 200b, and the third mounting hole 200c corresponding to the first nozzle cap 21, the second nozzle cap 22, and the fixed shaft 20 are provided in the outwardly convex decorative seat 200.

[0092] Exemplary first nozzle cap

[0093] As Figure 21As shown, further, in some embodiments of the present invention, a first spray cavity 211 corresponding to the third channel 103 is provided inside the first nozzle cap 21, and a strip-shaped spray outlet 212 communicating with the first spray cavity 211 is provided at the cap end of the first nozzle cap 21. Therefore, when the nozzle head cover 2 rotates to make the first nozzle cap 21 correspond to the third channel 103, the high-pressure liquid inside enters the first spray cavity 211, and then sprays out through the strip-shaped spray outlet 212 to present a strip-shaped first-shaped spray.

[0094] Exemplary second nozzle cap

[0095] As Figure 22 As shown, further, in some embodiments of the present invention, a second spray cavity 221 corresponding to the third channel 103 is provided inside the second nozzle cap 22, and a circular spray outlet 222 communicating with the second spray cavity 221 is provided at the cap end of the second nozzle cap 22. Therefore, when the nozzle head cover 2 rotates to make the second nozzle cap 22 correspond to the third channel 103, the high-pressure liquid inside enters the second spray cavity 221, and then sprays out through the circular spray outlet 222 to present a conical second-shaped spray. Here, the diameter of the circular spray outlet 222 is smaller than the inner diameter of the second spray cavity (not shown).
