DETAILED DESCRIPTION

[0021] The present application is further described in detail below in conjunction with the accompanying drawings.

[0022] The embodiment of the present application discloses a nozzle.

[0023] Reference Figure 1 and Figure 2 A nozzle includes an injection body 1 and an adjusting member 2. The injection body 1 is provided with an injection channel 10 for passing gas, and an air supply hole 11, an air outlet 12 and an air inlet 13 connected with the injection channel 10. The gas enters from the air inlet 13 and passes through the injection channel 10 before being ejected from the air outlet 12. The air supply hole 11 is used to supply primary air into the injection channel 10. The adjusting member 2 can change the communicating area between the air supply hole 11 and the injection channel 10, thereby changing the intake amount of the primary air.

[0024] In this embodiment, at least a portion of the jet body 1 extends along an axial line O, and the cross section of the jet body 1 is polygonal or circular.

[0025] One end face of the jet body 1 is an air outlet 12, and the other end face is an air inlet 13. The air supplement hole 11 is provided on the circumferential side wall close to the end face of the jet body 1 away from the air outlet 12. A plurality of air supplement holes 11 are evenly arranged along the circumference of the jet body 1.

[0026] The air injection passage 10 extends from an air inlet 13 to an air outlet 12 .

[0027] The adjusting member 2 includes a shielding portion 22 and an adjusting portion 21 . The adjusting portion 21 is used to drive the shielding portion 22 to move on the jet body 1 when subjected to an external force and enable the shielding portion 22 to change the connection area between the air supply hole 11 and the jet channel 10 .

[0028] In this embodiment, the shielding portion 22 and the adjusting portion 21 are integrally formed, and both the shielding portion 22 and the adjusting portion 21 extend along the axis O of the jet body 1. The shielding portion 22 moves along the axis O of the jet body 1, and during the movement, the air supply hole 11 can be completely connected, completely disconnected, or partially connected with the jet channel 10.

[0029] The shielding part 22 has a shielding wall along the circumference of the jet body 1, and the cross-sectional shape of the shielding wall is the same as the cross-sectional shape of the jet body 1. The shielding part 22 can be arranged on the outside or inside of the jet body 1. When the air supplement hole 11 needs to be closed, the shielding part 22 has a portion that completely overlaps with the air supplement hole 11 in the projection perpendicular to the axis O direction of the jet body 1; when the air supplement hole 11 is partially opened, the shielding part 22 has a portion that partially overlaps with the air supplement hole 11 in the projection perpendicular to the axis O direction of the jet body 1; when the air supplement hole 11 is fully opened, the shielding part 22 and the air supplement hole 11 do not overlap at all in the projection perpendicular to the axis O direction of the jet body 1.

[0030] The regulating portion 21 is disposed on a side of the shielding portion 22 away from the air supplement hole 11, and the regulating portion 21 is closer to the air outlet 12 than the shielding portion 22. Because the shielding portion 22 and the regulating portion 21 are integrally formed, in some embodiments, when the air supplement hole 11 is completely closed or partially opened, the regulating portion 21 may also overlap with the air supplement hole 11 in the projection perpendicular to the axis O of the jet body 1.

[0031] For better description, in this embodiment, the adjusting portion 21 is taken as the part where the user applies force. However, when the shielding portion 22 and the adjusting portion 21 are integrated or fixed together, the user may also directly apply force to the shielding portion 22 to directly drive the shielding portion 22 to move, without limiting the adjusting portion 21 to be the part where the user applies force.

[0032] In other embodiments, the shielding portion 22 and the adjusting portion 21 may be formed separately and fixed together by a pin or other means. The cross-sectional shapes of the shielding portion 22 and the adjusting portion 21 may be the same or different.

[0033] In other embodiments, the shielding portion 22 and the adjusting portion 21 are threadedly matched together, and the shielding portion 22 and the jet body 1 have a guide member along the axis O of the jet body 1, and the adjusting portion 21 is connected to the jet body 1 by rotation around the axis O of the jet body 1. When the adjusting portion 21 is rotated, the shielding portion 22 can be moved along the axis O of the jet body 1 due to the thread action between the shielding portion 22 and the adjusting portion 21 and the guiding action of the guide member. The guide member can be a guide rail extending along the axis O and a guide groove slidably connected to the guide rail.

[0034] In order to avoid accidentally touching the adjustment part 21 and causing the shielding part 22 to move during use, the nozzle also includes a protective member 3, which is provided with a accommodating space 30 and an operating port 31 connected to the accommodating space 30. The adjustment member 2 is located in the accommodating space 30 and is used to enable the user to apply force to the adjustment member 2 through the operating port 31.

[0035] In this embodiment, the protective member 3 is integrally formed with the jet body 1, and the protective member 3 is arranged at one end of the jet body 1 away from the air supply hole 11.

[0037] The shielding portion 22 is provided with a first air passage 220 which constitutes at least a part of the jet passage 10 . The regulating portion 21 is provided with a second air passage 210 which is connected to the first air passage 220 and constitutes at least another part of the jet passage 10 .

[0038] The adjusting member 2 is placed in the accommodating space 30 and the jet body 1. When the connecting area between the air supply hole 11 and the jet channel 10 needs to be adjusted, a tool is inserted into the accommodating space 30 to apply force to drive the adjusting portion 21. During normal use, the user is prevented from accidentally touching the adjusting member 2 and causing the adjusting member 2 to move, thereby keeping the air intake stable.

[0039] In this embodiment, the side wall of the accommodating space 30 is provided with a first internal thread, the adjusting portion 21 is provided with a first external thread threadably connected to the first internal thread, and the shielding portion 22 moves in the jet body 1 following the adjusting portion 21 .

[0040] In other embodiments, at least a portion of the sidewall of the jet channel 10 is provided with a second internal thread, the shielding portion 22 is provided with a second external thread threadably connected to the second internal thread, and the adjusting portion 21 rotates in the accommodating space 30 .

[0041] In other embodiments, at least part of the side walls of the accommodating space 30 and the jet channel 10 are provided with internal threads, parts of the adjusting portion 21 and the shielding portion 22 are threadedly connected to the internal threads, and the other part of the shielding portion 22 is used to form a shielding wall.

[0042] Reference Figure 3 In another embodiment, the protective member 3 is disposed outside the jet body 1, the accommodating space 30 is connected to the jet passage 10, the adjusting portion 21 is located in the accommodating space 30, at least part of the adjusting portion 21 is located outside the jet body 1, at least part of the shielding portion 22 is located in the jet passage 10, and at least another part of the adjusting portion 21 is connected to the shielding portion 22. The adjusting portion 21 is threadedly connected to the jet body 1 at the outer part of the jet body 1 and / or the adjusting portion 21 is threadedly connected to the jet body 1 at the inner part of the jet body 1, or the shielding portion 22 is threadedly connected to the jet body 1.

[0043] The caliber of the operating port 31 of the protective member 3 is larger than the caliber of the air outlet 12 of the jet body 1. The center of the adjusting portion 21 is formed with a central portion for extending into the interior of the jet body 1 and connected to the shielding portion 22. The central portion is provided with a central hole connected to the jet channel 10. The adjusting member 21 is formed with an outer ring portion sleeved on the outer side of the jet body 1 near the edge. The distance that the outer ring portion extends along the axis of the jet body 1 is greater than the maximum stroke of the shielding portion 22 when it is adjusted.

[0044] Reference Figure 4In another embodiment, the shielding portion 22 and the adjusting portion 21 are both located outside the jet body 1, and the protective member 3 is disposed outside the shielding portion 22 and the adjusting portion 21.
