[0050] Embodiment 1

[0051] Reference Figure 1 and Figure 2 , a schematic diagram of the overall structure of a multifunctional jet nozzle is provided, as Figure 1 A multifunctional jet nozzle comprises a mixing mechanism 100, which has an inner chamber 101, a water inlet 102 and an abrasive inlet 103 communicating with the inner chamber 101, and a first fluid passage 104 connected to the inner chamber 101; a rotating nozzle mechanism 200, which comprises a rotating head 201, a second fluid passage 202 provided on the rotating head 201, and a nozzle communicating with the second fluid passage 202; wherein a plurality of second fluid passages 202 are annularly distributed on the rotating head 201, and the rotating head 201 rotates, so that the plurality of second fluid passages 202 can be circulated to communicate with the first fluid passage 104.

[0052] In this embodiment, the number of second fluid passages 202 is three, and the number of nozzles is also three, the water inlet 102 is connected with a high-pressure water supply pipeline, in addition, the number of abrasive inlets 103 is two, which are used to add abrasives for different purposes, the water flow enters the inner side of the inner chamber 101 through the water inlet 102, different specifications of abrasives enter the inner side of the inner chamber 101 through the two abrasive inlets 103 respectively, and a switch member is arranged between the abrasive inlet 103 and the inner chamber 101, when the abrasive is fed through one of the abrasive inlets 103, the other abrasive inlet 103 is in a closed state.

[0053] The three nozzles have different functions, in this embodiment, the three nozzles are respectively set as cleaning nozzles, strengthening nozzles and cutting nozzles, according to the change of the actual application scene, when it is necessary to adjust the use of the nozzle 203, the rotating head 201 can be rotated, so that the three second fluid passages 202 can be circulated to correspond to the first fluid passage 104, thereby adjusting the communication relationship between the three nozzles and the first fluid passage 104, so as to switch the fluid inside the first fluid passage 104 to enter the inside of which nozzle, so that the nozzle 203 can adapt to different application scenes.

[0054] Specifically, the first fluid passage 104 is connected to the end of the inner chamber 101 away from the water inlet 102, and the first fluid passage 104 and the water inlet 102 are arranged off-axis.

[0055] The off-axis arrangement enables the water to enter the inner side of the inner chamber 101 and then cannot directly enter the inner side of the first fluid passage 104, so that the water can enter the inner side of the first fluid passage 104 after being stirred in the inner side of the inner chamber 101, and the water can be fully mixed with the abrasive in the inner side of the inner chamber 101.

[0056] Further, the rotating head 201 and the mixing mechanism 100 are connected through the connecting member 204, the connecting member 204 includes a connecting sheet 204a arranged on the rotating head 201, a connecting protrusion 204b arranged on the connecting sheet 204a, and connecting grooves 204c annularly arranged on the rotating head 201 and corresponding to the second fluid passages 202 one by one.

[0057] In this embodiment, the connecting sheet 204a is an arc sheet having a fixed end L1 and a micro-motion end L2, and an arc-shaped elastic section L3 between the fixed end L1 and the micro-motion end L2. When the rotating head 201 is rotated, the connecting sheet can be manually pulled to make the connecting protrusion 204b disengage from the inner side of the groove, so that the rotating head 201 can be rotated. When the connecting protrusion 204b needs to be positioned in the adjacent connecting groove 204c, the first fluid passage 104 and the adjacent second fluid passage 202 and the position of the nozzle correspond, so that the connecting groove 204c plays a prompting effect on the operator to determine whether the first fluid passage 104 and the second fluid passage 202 are positioned correspondingly.

[0058] In addition, a threaded hole is arranged on the locking mechanism, and a through hole corresponding to the threaded hole is arranged on the rotating head 201. The rotating head 201 and the mixing mechanism 100 are fixed through a connecting bolt 204d, and the connecting bolt 204d passes through the through hole and is connected to the threaded hole.

[0059] When the rotating head 201 needs to be adjusted, the connecting bolt 204d is loosened, and then the operation can be performed.

[0060] Operation process: according to the change of the actual application scene, when the nozzle 203 needs to be adjusted, the rotating head 201 can be rotated, so that the three second fluid passages 202 can be cyclically corresponded to the first fluid passage 104, so as to adjust the communication relationship between the three nozzles and the first fluid passage 104, so as to switch the fluid in the inner side of the first fluid passage 104 to enter the inner side of which nozzle, so that the nozzle 203 can adapt to different application scenes.

[0061] Embodiment 2

[0062] Reference Figures 3 to 9In order to adjust the rotating head 201 more conveniently, the embodiment is different from the first embodiment in that the rotating head 201 and the mixing mechanism 100 are positioned by a positioning mechanism 300 and a guiding locking mechanism 400; the positioning mechanism 300 comprises a sliding assembly 301 arranged on the locking mechanism and a contact assembly 302 arranged on the sliding assembly 301; the guiding locking mechanism 400 comprises an adjusting assembly 401 arranged on the rotating head 201 and clamping members 402 arranged on the adjusting assembly 401 and distributed in a ring shape and corresponding to the second fluid channel 202; and the sliding assembly 301 is provided with a communication port K.

[0063] The position of the adjusting assembly 401 can be adjusted, and the adjusting assembly 401 has two states according to the change of the position, one is an adjusting state and the other is a positioning state; when the adjusting assembly 401 is in the positioning state, the communication port K on the sliding assembly 301 corresponds to the first fluid channel 104, the first fluid channel 104 and the second fluid channel 202 can be communicated, and in the positioning state, the clamping members 402 and the contact assembly 302 are clamped, so that the relative rotation between the rotating head 201 and the mixing mechanism 100 can be avoided to cause the dislocation of the first fluid channel 104 and the second fluid channel 202.

[0064] When the adjusting assembly 401 is converted from the positioning state to the adjusting state, the contact assembly 302 drives the sliding assembly 301 to displace, so that the contact assembly 302 and the clamping members 402 are separated, thereby locking the rotating head 201 and the mixing mechanism 100; at this time, the rotating head 201 can be rotated; when the adjustment is completed, the adjusting assembly 401 is converted from the adjusting state to the positioning state; at this time, the contact assembly 302 can be clamped with the clamping members 402 again, so that the rotating head 201 and the mixing mechanism 100 are repositioned.

[0065] Moreover, in the process of converting the whole assembly from the positioning state to the adjusting state, the communication port K can be dislocated from the first fluid channel 104 and block the discharge port of the first fluid channel 104 in the case that the sliding assembly 301 moves, so that when the rotating head 201 and the mixing mechanism 100 rotate relatively, too much fluid can not enter the gap between the rotating head 201 and the mixing mechanism 100.

[0066] Specifically, the mixing mechanism 100 is provided with an inner groove 105 at a corresponding position of the first fluid channel 104; the sliding assembly 301 comprises a fixed column group 301a, which comprises a first column body 301a-1 arranged in the inner groove 105 and a second column body 301a-2 coaxially arranged with the first column body 301a-1, and a gap corresponding to the first fluid channel 104 is formed between the first column body 301a-1 and the second column body 301a-2; a first spring 301b is sleeved on the outer side of the first column body 301a-1; and a displacement member 301c is slidingly sleeved on the outer sides of the first column body 301a-1 and the second column body 301a-2 and is in contact with the first spring 301b.

[0067] Two limiting grooves are formed in the groove wall of the inner groove 105, and limiting protrusions are arranged at both ends of the displacement member 301c, the two limiting protrusions slidingly extend to the inner sides of the two limiting grooves, so that the displacement member 301c is prevented from rotating, and the gap between the first column body 301a-1 and the second column body 301a-2 can prevent the first column body 301a-1 and the second column body 301a-2 from blocking the fluid flowing out of the first fluid channel 104.

[0068] When the adjusting assembly 401 is switched from the positioning state to the adjusting state, the clamping member 402 can be in contact with the contact sheet, so that the displacement member 301c can slide along the first column body 301a-1 and the second column body 301a-2, and press the first spring 301b, so that the first spring 301b is deformed.

[0069] Further, the clamping member 402 has a contact slope 402a and is provided with a clamping groove 402b, and the clamping member 402 further has a flush surface 402c connected with the contact slope 402a; the contact assembly 302 comprises a contact part 302a capable of being in contact with the contact slope 402a and a clamping pin part 302b capable of being clamped in the inner side of the clamping groove 402b.

[0070] In this embodiment, the contact part 302a is fixedly connected with the displacement member 301c, the clamping pin part 302b is fixed on the contact part 302a, and the clamping groove 402b is located on the side of the clamping member 402 away from the first fluid channel 104.

[0071] When the adjusting assembly 401 is switched from the positioning state to the adjusting state, the contact slope 402a will press the contact part 302a, so that the contact part 302a drives the displacement member 301c to move and press the first spring 301b, and in this process, the clamping pin part 302b clamped in the inner side of the clamping groove 402b is separated from the inner side of the clamping groove 402b along with the sliding of the contact part 302a, so that the positioning relationship between the rotating head 201 and the mixing mechanism 100 is released.

[0072] Further, the abutting slope 402a has a contact end 402a-1 at one end and a transition end 402a-2 at the other end connected to the flush surface 402c; the connecting rail body 401b has an inner arc surface M1, and the inner arc surface M1 is connected to the flush surface 402c.

[0073] When the adjustment assembly 401 is in the positioning state, the contact end 402a-1 is closer to the first fluid passage 104 than the transition end 402a-2, wherein the abutting part 302a has a connecting section 302a-1 connected to the displacement member 301c and a force receiving end 302a-2 extending to the outside of the inner recess 105, and the contact end 402a-1 is closer to the first fluid passage than the force receiving end 302a-2, and when the adjustment assembly 401 is switched from the positioning state to the adjustment state, the clamping member 402 is pushed to move towards the abutting part 302a, the contact end 402a-1 abuts against the force receiving end 302a-2, so that the force receiving end 302a-2 is forced to drive the displacement member 301c through the connecting section 302a-1 to press the first spring 301b, until the contact position of the force receiving end 302a-2 and the clamping member 402 transitions from the transition end 402a-2 to the flush surface 402c, at which time the displacement member 301c stops moving.

[0074] Further, the rotating head 201 is provided with a circular groove 201a; the adjustment assembly 401 includes a rotating ring 401a slidably arranged on the inner side of the circular groove 201a; a connecting rail body 401b intermittently arranged between the clamping members 402; and an extension rod 401c connected to the rotating ring 401a and extending to the outer side of the rotating head 201.

[0075] In this embodiment, the rotating head 201 is provided with an extension groove 201b, the width of the extension rod 401c is adapted to the width of the extension groove 201b, and the extension rod 401c can move along the extension groove 201b towards or away from the mixing mechanism 100, in addition, the rotating ring 401a can rotate synchronously with the rotating head 201, and in this embodiment, the number of extension rods 401c is two, and the number of extension grooves 201b is also two.

[0076] When the rotating ring 401a is driven by the extension rod 401c to move towards the mixing mechanism 100, and the extension rod 401c reaches the first end of the extension groove 201b, the adjustment assembly 401 is switched from the positioning state to the adjustment state, and when the rotating ring 401a is driven by the extension rod 401c to move away from the mixing mechanism 100, and the extension rod 401c reaches the second end of the extension groove 201b, the adjustment assembly 401 is switched from the adjustment state to the positioning state.

[0077] In addition, the number of the clamping members 402 is three, the three clamping members 402 are fixed on the inner side wall of the rotating ring 401a, further, the positions of the three clamping members 402 correspond to the positions of the three second fluid channels 202 one by one, further, the connecting rail 401b is in a circular arc type, is fixed intermittently between the three clamping members 402, and the two ends of the connecting rail 401b are connected to two clamping members 402 respectively, when the rotating head 201 rotates, under the pushing force of the first spring 301b, the stressed end 302a-2 is transitioned from the flush surface 402c to the inner arc surface M1, moves along the inner arc surface M1, and reaches the flush surface 402c of the other clamping member 402.

[0078] Further, the mixing mechanism 100 is provided with the annular protrusion 106, the rotating head mechanism 200 is provided with the connecting buckle 206, and the mixing mechanism 100 and the rotating head mechanism 200 are rotationally connected through the annular protrusion 106 and the connecting buckle 206.

[0079] Wherein, the rotating head 201 is provided with the clamping groove, the diameter of the annular protrusion 106 is matched with the diameter of the circular clamping groove, the rotating head 201 and the mixing mechanism 100 are in a connected state, the annular protrusion 106 enters the inner side of the clamping groove, the inner diameter of the connecting buckle 206 is smaller than the outer diameter of the annular protrusion 106, the annular protrusion 106 is buckled, so that the annular protrusion 106 cannot be separated from the inner side of the clamping groove, so that the rotating head 201 and the mixing mechanism 100 can rotate relatively, but will not be separated.

[0080] In order to improve the sealing performance of the entire spray head 203, a dynamic sealing structure is arranged between the annular protrusion 106 and the connecting buckle 206, and a sealing pad is also arranged on the side where the displacement member 301c and the first fluid channel 104 are in contact. This sealing means is a prior art and will not be described in detail here.

[0081] The remaining structures are the same as those of example 1.

[0082] Operation process: the position of the adjusting assembly 401 can be adjusted, according to the change of the position, there are two states, one is an adjusting state, and the other is a positioning state. When the adjusting assembly 401 is in the positioning state, the communication port K on the sliding assembly 301 corresponds to the first fluid channel 104, the first fluid channel 104 and the second fluid channel 202 can be communicated, and in this positioning state, the clamping member 402 and the contact assembly 302 are clamped, which can avoid the problem that the relative rotation between the rotating head 201 and the mixing mechanism 100 causes the misalignment of the first fluid channel 104 and the second fluid channel 202, so that the rotation and positioning of the rotating head 201 and the mixing mechanism 100 are more convenient.

[0083] Example 3

[0084] Reference Figure 7 andFigure 10 The difference between this embodiment and the above embodiments is that the rotating ring 401a is provided with a prompt mechanism 500, which comprises a middle ring 501 arranged on the rotating ring 401a and coaxial with the rotating ring 401a, and elastic sheets 502 annularly arranged on the middle ring 501 and corresponding to the clamping grooves 402b.

[0085] Specifically, when the rotating head 201 rotates, the rotating ring 401a can be driven to rotate relative to the mixing mechanism 100, so as to drive the middle ring 501 to rotate relative to the mixing mechanism 100.

[0086] The elastic sheets 502 are metal sheets, and the number of the elastic sheets 502 is three. The three elastic sheets 502 correspond to the three clamping grooves 402b, and there is an included angle between the three elastic sheets 502 and the three clamping grooves 402b. When the adjusting assembly 401 is in the adjusting state, the clamping pin portion 302b generates a position in the direction away from the first fluid channel 104. When the clamping pin portion 302b rotates and approaches the next clamping groove 402b, the clamping pin portion 302b will touch the elastic sheet 502. When the clamping pin portion 302b and the next clamping groove 402b are in a corresponding position, the clamping pin portion 302b is just separated from the bent elastic sheet 502, and at this time, the elastic vibration emits a prompt sound.

[0087] The rest of the structure is the same as that of the embodiment 2.

[0088] Operation process: When the adjusting assembly 401 is in the adjusting state, the clamping pin portion 302b generates a position in the direction away from the first fluid channel 104. When the clamping pin portion 302b rotates and approaches the next clamping groove 402b, the clamping pin portion 302b will touch the elastic sheet 502. When the clamping pin portion 302b and the next clamping groove 402b are in a corresponding position, the clamping pin portion 302b is just separated from the bent elastic sheet 502, and at this time, the elastic vibration emits a prompt sound, so that the user knows that the first fluid channel and the second fluid channel are in a corresponding position at this time.
