[0024] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-6 As shown, this embodiment discloses a powder spraying rod, including an inner bottle 1, a pusher head 2, a screw cap 3, an outer shell 4, an outer cap 5, and a conduit 6. The upper end of the inner bottle 1 has an opening, and part of the inner bottle 1 is located inside the outer shell 4. The pusher head 2 is installed at the upper opening of the inner bottle 1 and is threaded into the opening of the inner bottle 1. The pusher head 2 is at least partially located inside the outer shell 4. The outer shell 4 includes a housing 41 and a shoulder sleeve 42. The shoulder sleeve 42 is fixedly installed at the upper end of the housing 41. The inner wall of the shoulder sleeve 42 has a second limiting groove 421, and the outer wall of the pusher head 2 has a first limiting block 2 corresponding to the second limiting groove 421. 4. The second limiting groove 421 can limit the up and down sliding of the first limiting block 24. The push head 2 can slide up and down along the outer shell 4. The inner bottle 1 can be elastically deformed. The inner bottle 1 has a corrugated tube-like deformable part that can be pressed up and down. The guide tube 6 is located inside the inner bottle 1. The upper end of the guide tube 6 is connected to the push head 2. The push head 2 has a nozzle 21. The nozzle 21 is connected to the guide tube 6. The powder in the inner bottle 1 is compressed by air and sprayed from the guide tube 6 to the nozzle 21. The outer cover 5 is detachably installed on the shoulder sleeve 42, covering the push head 2 and the screw cap 3 inside, which plays a role in dust protection.

[0026] More preferably, at least one guide bar 422 is provided in the second limiting groove 421, and at least two first limiting blocks 24 are provided. A second guide groove 241 is formed between two adjacent first limiting blocks 24. The guide bar 422 is located in the second guide groove 241. The guide bar 422 and the second guide groove 241 cooperate to prevent the pusher head 2 from rotating, so that the pusher head 2 can only be pressed up and down, and the orientation of the nozzle 21 of the pusher head 2 will not change when it is pressed.

[0027] The cap 3 is rotatably mounted on the press head 2. The outer wall of the press head 2 is provided with a first limiting groove 23. The inner wall of the cap 3 is provided with a second limiting block 34 corresponding to the first limiting groove 23. The second limiting block 34 is inserted into the first limiting groove 23 so that the cap 3 and the press head 2 can rotate relative to each other. The cap 3 is provided with a through hole 31. The nozzle 21 is located on the side wall of the press head 2. The through hole 31 is located on the side wall of the cap 3. The cap 3 rotates so that the through hole 31 coincides with or is offset from the nozzle 21. When the through hole 31 coincides with the nozzle 21, the nozzle 21 can spray powder outward through the through hole 31. When the through hole 31 is offset from the nozzle 21, the cap 3 can seal the nozzle 21 to prevent moisture from entering the nozzle 21 when not in use.

[0028] The inner top surface of the screw cap 3 is provided with a locking block 32, and the upper end surface of the push head 2 is provided with a first ring plate 22. The first ring plate 22 extends upward and includes a misaligned area 221 and a third groove 222. The misaligned area 221 and the third groove 222 are separated by a first protrusion 223. The first ring plate 22 is provided with two transverse grooves 225, one of which is located below the first protrusion 223. The transverse groove 225 located below the first protrusion 223 connects to the third groove 222. The first protrusion 223 has the ability to deform downwards. The locking block 32 can move between the misaligned area 221 and the third groove 222 as the cap 3 rotates, passing over the first protrusion 223. When the locking block 32 is in the third groove 222, the through hole 31 coincides with the nozzle 21. The locking block 32 is blocked by the first protrusion 223 to prevent the cap 3 from rotating, thus fixing the cap 3 when the through hole 31 coincides with the nozzle 21. When the locking block 32 is in the misaligned area 221, the through hole 31 and the nozzle 21 are misaligned.

[0029] The misaligned area 221 includes a first groove 2211, a second groove 2212, and a second protrusion 224. The first groove 2211 and the second groove 2212 are separated by the second protrusion 224. Another transverse groove 225 is located below the second protrusion 224. The transverse groove 225 located below the second protrusion 224 connects to the second groove 2212. The second groove 2212 is located at the end of the first groove 2211 away from the third groove 222. The second protrusion 224 has the same structure as the first protrusion 223. The locking block 32 can move between the first groove 2211 and the second groove 2212 as the cap 3 rotates, passing over the second protrusion 224. The locking block 32 is blocked by the second protrusion 224 in the second groove 2212 to prevent the cap 3 from rotating, thus fixing the cap 3 when closing the nozzle 21.

[0030] More preferably, the upper sides of the first protrusion 223 and the second protrusion 224 are provided with rounded corners, the lower end surface of the locking block 32 is higher than the upper end surface of the second groove 2212, and the lower end surface of the locking block 32 is lower than the upper end of the first protrusion 223 and the second protrusion 224, which makes it easier for the locking block 32 to pass over the first protrusion 223 and the second protrusion 224, making the screw cap 3 rotate more easily, and providing a better feel when the locking block 32 enters and passes over the first protrusion 223 and the second protrusion 224.

[0031] The cap 3 is provided with a second ring plate 33, which is located on the inner side of the cap 3. A slot 331 is formed between the second ring plate 33 and the inner side wall of the cap 3. The first ring plate 22 is inserted into the slot 331, and the locking block 32 is located in the slot 331, which can make the cap 3 and the push head 2 more stable. A fourth groove 226 is formed inside the first ring plate 22, and the second ring plate 33 is located in the fourth groove 226. The inner top surface of the cap 3 is provided with multiple reinforcing ribs 332. The lower end of the reinforcing ribs 332 abuts against the inner bottom surface of the fourth groove 226. The reinforcing ribs 332 can strengthen the connection structure between the cap 3 and the push head 2 and prevent the cap 3 from being deformed by pressing.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
