[0038] As Figure 1 shown, the present application discloses a nozzle holder adapted to connect an intake pipe and a nozzle. The nozzle holder includes: an air pipe joint 1, a nozzle joint 2, a ventilation pipe 3, a first sleeve 4, a second sleeve 5, a longitudinal bracket 6, and a spring 7.

[0039] The intake end of the air pipe joint 1 is adapted to connect to the intake pipe, and the outlet end of the air pipe joint 1 is connected to the intake end of the ventilation pipe 3.

[0040] The intake end of the nozzle joint 2 is connected to the outlet end of the ventilation pipe 3, and the outlet end of the nozzle joint 2 is adapted to connect to the nozzle.

[0041] The first sleeve 4 is sleeved outside the spring 7, and the first end of the first sleeve 4 is connected to the nozzle joint 2.

[0042] The second sleeve 5 is sleeved outside a part of the air pipe joint 1 and a part of the ventilation pipe 3. The inner diameter of the first end of the second sleeve 5 is smaller than the inner diameter of the second end of the first sleeve 4. The first end of the second sleeve 5 is the end close to the nozzle joint 2, and the second end of the first sleeve 4 is the end far from the nozzle joint 2.

[0043] The longitudinal bracket 6 is adapted to support the second sleeve 5.

[0044] The spring 7 is sleeved outside the ventilation pipe 3. Along the extension direction of the ventilation pipe 3, the spring 7 is located between the first end of the second sleeve 5 and the nozzle joint 2.

[0045] The nozzle bracket disclosed in this application is successively connected with an intake pipe, a pipe joint 1, a ventilation pipe 3, a nozzle joint 2 and a nozzle from left to right. Additionally, a second sleeve 5 is sleeved outside a part of the pipe joint 1 and a part of the ventilation pipe 3, the spring 7 is sleeved outside the ventilation pipe 3, and a first sleeve 4 is sleeved outside the spring 7. The longitudinal bracket 7 is fixedly connected to the second sleeve 5 and is adapted to support the second sleeve 5.

[0046] As Figure 2 shown, the pipe joint 1 includes a first air duct 12 and a first connection channel 11.

[0047] The intake end of the first air duct 12 is connected to the intake pipe, and the outlet end of the first air duct 12 is connected to the intake end of the first connection channel 11. The outlet end of the first connection channel 11 is connected to the intake end of the ventilation pipe 3.

[0048] The nozzle joint 2 includes a second air duct 21, a second connection channel 22 and a groove portion 221.

[0049] The first end of the groove portion 221 is connected to the outlet end of the ventilation pipe 3, and the second end of the groove portion 221 is connected to the intake end of the second connection channel 22. The outlet end of the second connection channel 22 is connected to the intake end of the second air duct 21. The outlet end of the second air duct 21 is connected to the nozzle.

[0050] The outer periphery of the first end of the groove portion 221 has a protrusion 222. The inner diameter of the protrusion 222 on the side close to the groove portion 221 is larger than the inner diameter on the side far from the groove portion 221; the outer edge of the protrusion 222 is an inclined surface.

[0051] The arrangements of the groove portion 221 and the protrusion 222 are for facilitating the installation and clamping of the first sleeve 4. The protrusion 222 has an inclined surface inclined towards the ventilation pipe 3. The first sleeve 4 is sleeved outside the spring 7, and then is pushed towards the direction of the groove portion 221 with an external force along the inclined surface of the protrusion 222. Because the inner diameter of the protrusion 222 on the side close to the groove portion 221 is larger than the inner diameter on the side far from the groove portion 221, during the process of the first sleeve 4 being pushed along the protrusion 222, the first sleeve 4 will deform and thus is relatively easy to slide into the groove 221 and is then clamped by the groove 221.

[0052] In addition, the air outlet end of the first connection channel 11 and the air inlet end of the second connection channel 22 both have internal threads, and both the air inlet end and the air outlet end of the ventilation pipe 3 have external threads. The external cross-section of the first connection channel 11 and the second connection channel 22 perpendicular to the ventilation pipe 3 is polygonal.

[0053] The air outlet end of the first connection channel 11 and the air inlet end of the second connection channel 22 are respectively threadedly connected to the air inlet end of the ventilation pipe 3, and the external cross-sections of the first connection channel 11 and the second connection channel 22 perpendicular to the ventilation pipe 3 are both polygonal, such as hexagons. The threaded connection method and the polygonal structure enable the detachable connection and convenient separation between the tracheal connector 1, the nozzle connector 2 and the ventilation pipe 3 respectively, which is convenient for cleaning the metal debris generated by the friction between the spring 7 sleeved outside the ventilation pipe 3 and the ventilation pipe 3, and also convenient for directly replacing the first sleeve 4 with too much metal debris remaining.

[0054] Furthermore, the inner diameters of the ventilation pipe 3, the first air duct 12 and the second air duct 21 are equal. In this way, the inner diameter of the nozzle bracket after the whole connection is completed is unobstructed, and the inner wall is flat without convex surfaces, avoiding the remaining metal debris on the inner wall during the working process and affecting the air intake efficiency of the equipment.

[0055] As Figure 2 shown, in this embodiment, the tracheal connector 1 further includes a gasket 13.

[0056] The gasket 13 is sleeved on the outer wall of the ventilation pipe 3, and the gasket 13 is located between the first connection channel 11 and the longitudinal bracket 6.

[0057] When the nozzle bracket is in the inhalation state, the second sleeve 5 moves towards the spring 7 to press the spring, and then the spring rebounds, and the second sleeve 5 moves away from the spring. During the process of the second sleeve 5 moving from the direction away from the spring to the stationary state, the surface where the longitudinal bracket 6 and the second sleeve 5 coincide contacts and slightly collides with the second connection channel 22. Since the second connection channel 22 is made of stainless steel, this collision and extrusion will cause wear on the contact surface. By setting the gasket 13 between the first connection channel and the longitudinal bracket 6, that is, at the position of the coincident surface described above, the wear of the contact surface is avoided.

[0058] As Figure 1 and Figure 2 shown, the longitudinal bracket 6 further includes: a middle hole structure 61.

[0059] The middle hole structure 61 is an oblong ellipsoid, and the middle hole structure 61 is adapted to cooperate with the connecting piece to fix the nozzle bracket on the fixing plate, and is adapted to cooperate with the connecting piece to enable the longitudinal bracket 6 to slide on the fixing plate.

[0060] An active guide rail is provided on the fixed plate of the fixed nozzle support. The nozzle support can move along the active guide rail, which is suitable for adjusting the working position of the nozzle support. A middle hole structure 61 is provided on the longitudinal support 6 of the nozzle support. This middle hole structure 61 can not only cooperate with the connecting piece to fix the nozzle support on the fixed plate, but also be suitable for cooperating with the connecting piece to enable the longitudinal support 6 to move along the axial direction of the guide rail. The middle hole structure 61 cooperates with the active guide rail, making the moving range of the nozzle support larger and the selectable working angles of the adjustable nozzle support more.

[0061] Generally speaking, a nozzle support provided in this application includes an air pipe joint, a nozzle joint, an air pipe, a first sleeve, a second sleeve, a longitudinal support and a spring. The spring is sleeved outside the air pipe, and the first sleeve is sleeved outside the spring, so that the metal debris generated by the friction between the spring and the air pipe falls into the first sleeve, rather than directly falling on the components contacted by the nozzle joint. The air pipe joint and the nozzle joint are respectively threadedly connected to the air pipe, making the air pipe joint, the suction pipe joint and the air pipe easy to disassemble. Therefore, it is convenient to clean the metal debris falling in the air pipe or directly replace the air pipe, avoiding the accumulation of metal debris in the air pipe and further avoiding the overflow of the debris in the air pipe and falling on the components.

[0062] The above embodiments are only illustrative of the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
