Description

Technical Field

[0059] In this embodiment, a support 10 is further included, and the telescopic tube 20 is slidably installed on the support 10, and the movable control mechanism is arranged between the support 10 and the outlet nozzle 30; or, the movable control mechanism is arranged between the telescopic tube 20 and the outlet nozzle 30, and the movable control mechanism cooperates with the outlet nozzle 30. This embodiment specifically adopts the former.

[0060] In this embodiment, the outlet nozzle 30 is rotatably mounted on the outlet end of the telescopic tube 20. The outlet nozzle 30 and the telescopic tube 20 are rotatably matched by providing a rotational matching hole 21 at the front end of the telescopic tube 20, and providing a rotation shaft 31 on both sides of the outlet nozzle 30. The rotation of the outlet nozzle 30 relative to the telescopic tube 20 is achieved by pivotally matching the rotation shaft 31 with the rotational matching hole 21.

[0061] The movable control mechanism controls the outlet nozzle 30 to move relative to the telescopic tube 20 as the telescopic tube 20 moves. When the telescopic tube 20 extends forward, the movable control mechanism controls the outlet nozzle 30 to move forward. Figure 3 , Figure 5 , Figure 7 and Fig. 9 When the telescopic tube 20 is retracted, the activity control mechanism controls the outlet nozzle 30 to move in the reverse direction. Figure 3 , Figure 5 , Figure 7 and Fig. 9 From the perspective of the embodiment of the present invention, the reverse movement of the outlet nozzle 30 refers to a clockwise rotation.

[0062] The support 10 is provided with a telescopic rail 11, and the telescopic tube 20 is driven to move forward and backward along the telescopic rail 11 by a telescopic control mechanism 40; the telescopic tube 20 is provided with a transmission rack 22 that is slidably matched with the telescopic rail 11, and the telescopic control mechanism 40 includes a telescopic drive motor 41 and a telescopic drive gear 42, the telescopic drive motor 41 controls the rotation of the telescopic drive gear 42, and the telescopic drive gear 42 is meshed with the transmission rack 22 to drive the telescopic tube 20 to move forward and backward. The telescopic drive motor 41 and the telescopic drive gear 42 are attached to the support 10, the transmission rack 22 is arranged at the bottom of the telescopic tube 20, and the telescopic drive gear 42 is arranged below the transmission rack 22.

[0063] In this embodiment, the movable control mechanism uses mechanical transmission to control the rotation amplitude.

In this embodiment, the movable control mechanism includes a turning guide rail 51 arranged on the support 10 and a turning shaft 32 arranged on the outlet nozzle 30 and movably coordinated with the turning guide rail 51; or, the movable control mechanism includes a turning guide rail 51 arranged on the outlet nozzle 30 and a turning shaft 32 arranged on the support 10 and movably coordinated with the turning guide rail 51; when the telescopic tube 20 telescopes, the turning shaft 32 slides along the turning guide rail 51, and controls the rotation amplitude of the outlet nozzle 30 relative to the telescopic tube 20 by the inclination angle of the turning guide rail 51. In this embodiment, the turning shaft 32 is arranged in the middle of the upper end surface of the outlet nozzle 30.

[0064] The said turning guide rail 51 comprises more than two turning sections with different inclination angles, and each turning section corresponds to a different rotation amplitude. In this embodiment, the said turning guide rail 51 comprises a first turning section 511, a second turning section 512, a third turning section 513, a front end 514 and a rear end 515; when the said telescopic tube 20 is in the retracted position, the said turning shaft 32 is limitedly matched with the rear end 515 of the said turning guide rail 51; when the said telescopic tube 20 is extended forward, the said turning shaft 32 slides to the front end 514 of the said turning guide rail 51 and / or continues to slide forward and disengage from the front end 514.

[0065] When the outlet nozzle 30 moves relative to the telescopic tube 20, the outlet end of the telescopic tube 20 forms a first outlet 301 and a second outlet 302; when the telescopic tube 20 is in the first extension stroke, the outlet nozzle 30 is correspondingly located in the first movement range, the first outlet 301 is opened, and the second outlet 302 is closed (such as Figure 2 and Figure 3 When the telescopic tube 20 is in the second extension stroke, the outlet nozzle 30 is correspondingly located in the second activity range, and the first outlet 301 and the second outlet 302 are both opened (as shown in FIG. Figure 4 and Figure 5 When the telescopic tube 20 continues to move forward to the third extension stroke, the first outlet 301 is closed and the second outlet 302 is opened (as shown); Figure 6 and Figure 7 shown).

[0066] In this embodiment, the outlet nozzle 30 is rotatably mounted on the outlet end of the telescopic tube 20, the outlet of the outlet nozzle 30 forms the first outlet 301, and the gap between the upper end surface 33 of the outlet nozzle 30 and the top wall of the telescopic tube 20 forms the second outlet 302; when the outlet nozzle 30 is located in the first movable range, the upper end surface 33 of the outlet nozzle 30 abuts against the top wall of the telescopic tube 20, thereby closing the second outlet 302, and the inlet of the outlet nozzle 30 is connected to the inner cavity of the telescopic tube 20, thereby opening the second outlet 302. The first outlet 301; the outlet nozzle 30 is located in the second movable range, the upper end surface 33 of the outlet nozzle 30 is separated from the top wall of the telescopic tube 20, thereby opening the second outlet 302, and the inlet of the outlet nozzle 30 is connected with the inner cavity of the telescopic tube 20, thereby partially opening the first outlet 301; the outlet nozzle 30 is located in the third movable range, the inlet of the outlet nozzle 30 is staggered and not connected with the inner cavity of the telescopic tube 20, thereby closing the first outlet 301, and the second outlet 302 is in an open state.

[0067] The working process of the telescopic device of this embodiment is briefly described as follows:

[0068] like Figure 2 , 3 As shown in Figure 10, when the telescopic tube 20 is in the retracted position, the change-of-direction shaft 32 is limitedly engaged with the rear end 515 (first change-of-direction section 511) of the change-of-direction guide rail 51; the outlet nozzle 30 is located in the first movable range, and the upper end surface 33 of the outlet nozzle 30 abuts against the top wall of the telescopic tube 20, thereby closing the second outlet 302, and at the same time, the inlet of the outlet nozzle 30 is connected to the inner cavity of the telescopic tube 20, thereby opening the first outlet 301; at this time, the second outlet 302 is closed, the first outlet 301 is opened, and the fluid outflow direction is approximately horizontally forward.

[0069] like Figure 4 and Figure 5 As shown, when the telescopic tube 20 is extended forward under the drive of the telescopic drive motor 41, the direction-changing shaft 32 slides to the second direction-changing section 512 of the direction-changing guide rail 51; the outlet nozzle 30 drives the outlet nozzle 30 to change direction and rotate upward through the cooperation of the direction-changing shaft 32 and the direction-changing guide rail 51 of the support 10, and the outlet nozzle 30 is located in the second range of motion; at this time, the upper end surface 33 of the outlet nozzle 30 rotates and separates from the top wall of the telescopic tube 20 to open the second outlet 302, and the inlet of the outlet nozzle 30 is connected to the inner cavity part of the telescopic tube 20 to partially open the first outlet 301. That is, at this time, the first outlet 301 and the second outlet 302 are opened at the same time, achieving the effect of fluid flowing out of the dual outlets at the same time. In this embodiment, the fluid outflow direction of the first outlet 301 is inclined upward by 21° relative to the water surface, and of course other angle values ​​can also be designed according to needs.

[0070] like Figure 6 and Figure 7 As shown, the telescopic tube 20 continues to extend forward under the drive of the telescopic drive motor 41, and the direction-changing shaft 32 slides to the third direction-changing section 513 of the direction-changing guide rail 51. When the direction-changing shaft 32 slides to the front end 514 of the direction-changing guide rail 51, the outlet nozzle 30 is located in the third movable range, and the inlet of the outlet nozzle 30 is staggered and not connected with the inner cavity of the telescopic tube 20, thereby closing the first outlet 301, and the second outlet 302 remains in an open state. In this embodiment, the rotation amplitude of the outlet nozzle 30 at this position reaches the maximum value (40° upward tilt relative to the horizontal plane, of course, other angle values ​​can also be designed as needed), and the fluid flows out from the second outlet 302.

[0071] like Figure 8 , 9As shown in FIG. 11 , the telescopic tube 20 continues to slide forward and detaches from the front end 514. The telescopic tube 20 continues to drive the outlet mouth 30 to move forward under the drive of the telescopic drive motor 41. During the process of the outlet mouth 30 continuing to move forward, the angular direction of the first outlet 301 and the second outlet 302 is kept unchanged, and only the position is moved forward.

[0072] Second embodiment (electrically controlled rotation range)

[0073] like Figures 12 to 20 As shown, the main difference between this embodiment and the first embodiment is that: in this embodiment, the activity control mechanism includes a drive motor 52 and a transmission mechanism, and the drive motor 52 and the transmission mechanism are arranged on the telescopic tube 20. The drive motor 52 drives the transmission mechanism, and the transmission mechanism further drives the outlet nozzle 30 to move relative to the telescopic tube 20.

[0074] The transmission mechanism may adopt any one of the following or a combination of two or more: connecting rod transmission, gear transmission, synchronous belt transmission, chain transmission, guide groove transmission, fluid force and limiter coordination control, screw transmission. In this embodiment, the transmission mechanism includes an angle driving swing rod 521 that is linked with the driving motor 52, and a transmission connecting rod 522 that is movably connected between the angle driving swing rod 521 and the outlet nozzle 30; when the driving motor 52 rotates, the angle driving swing rod 521 is driven to swing, and then the outlet nozzle 30 is driven to rotate relative to the telescopic tube 20 through the transmission connecting rod 522. In this embodiment, the driving motor 52 is installed on the telescopic tube 20 and moves synchronously with the telescopic tube 20.

[0075] The rest of the structure and working process of the telescopic device of this embodiment are basically similar to those of the first embodiment, and will not be described in detail here.

[0076] It should be noted that the mouth in the above two embodiments can also be replaced by a guide portion (not shown), such as a guide plate, and the guide portion is movably attached to the outlet end of the telescopic tube 20. The direction of fluid outflow from the outlet end of the telescopic tube 20 can be changed by the movement of the guide portion, which can also achieve the purpose of the present invention.

[0077] In other embodiments, the mouth or the guide portion may be slidably mounted on the telescopic tube 20; or, the mouth or the guide portion may be rotatably and slidably mounted on the telescopic tube 20, so that the flow direction of the fluid at the outlet end of the telescopic tube 20 can be adjusted.
