[0013] A method for using a flush nozzle for a floor scrubber comprises the following steps:

[0014] S1. The connecting sleeve is fixed on the water pipe for inputting water flow. When the nozzle needs to be installed, the connecting shell is aligned with the connecting sleeve and inserted into the inside, and the threaded connection is made through the threaded connection groove A and the threaded connection groove B. When the threaded connection is rotated, the connecting sleeve will gradually move to the bottom of the connecting shell, and the expansion shell will be pressed down. The expansion shell moves on the vertical path block, and will gradually move outward with the downward pressure, and pull the sealing ring in four directions at the same time to expand it, so as to fit closely to the inner wall of the connecting sleeve, increase the friction at the connection and keep the connection stable;

[0015] S2, the wheel limit block is engaged with the wheel engaging groove on the impact water wheel through the wheel groove block on the surface. When the water flows through the nozzle shell, if the water flow is large, the wheel limit blocks on both sides of the nozzle shell will impact and press down to both sides. At this time, the wheel limit block is no longer in contact with the impact water wheel. When the water flows through, one side is blocked by the water flow baffle, and the water flow can only flow through the lower half of the impact water wheel, continuously impacting the impact water wheel to make it rotate. When the water flow decreases, the wheel limit block will bounce up again under the action of the block spring to clamp the impact water wheel;

[0016] S3, the impact water wheel drives the eccentric wheel to rotate through the water wheel shaft in the middle, and the wheel sleeve moves vertically and horizontally following the rotation of the eccentric wheel, continuously driving the vertical driven rod to make vertical reciprocating movements, and the top sleeve block is sleeved on the surface of the sliding connection shaft, which will push the sliding connection shaft to reciprocate, and the sliding connection shaft will be continuously lifted and lowered, so that the rotating column connected to it reciprocates, and the reciprocating rotation is output to the swing rod at the other end, so that it swings back and forth;

[0017] S4. The swing rod continuously lifts and lowers the rotating input disk by rotating the connecting rod to realize the reciprocating rotation of the rotating shell. When the rotating shell is vertically downward, the traction rope is tightened, and the mobile platform is pushed out by the push-out spring installed on the outer mounting plate to the lowest point on the rotating shell. When the rotating shell is transferred to both sides, the traction rope will pull the mobile platform. At this time, the mobile platform will move upward on the rotating shell. In the process of the rotating shell moving up and down, the two sides push and pull the driven push-pull seat through the rotating connecting shaft through the hinge rod. When moving outward at the same time, the elastic water outlet is pulled open by the deformation push-pull column, so that the two sides of the outlet become longer and narrower, and the original straight-rushing water column is converted into a fan-shaped water mist. When moving inside the box, the elastic water outlet is pushed, pulled and restored inside the box.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In the present invention, the water pressure follower mechanism is set to realize opening and closing swing according to the size of the water flow. When the water flow increases, the structure is unlocked, and the swing effect in the direction perpendicular to the water flow is realized through the action of the eccentric wheel and the driven rod. This design enables the nozzle to automatically adjust the spraying mode according to the size of the water flow, thereby improving the adaptability and efficiency of the floor scrubber.

[0020] In the present invention, by setting up the follow-up deformation mechanism, dynamic adjustment of the nozzle when the water flow size changes is realized, and the reciprocating swing of the rotating shell drives the moving platform to move up and down, thereby changing the shape of the elastic water outlet and realizing the switching of the water column mode. This design enables the nozzle to output a straight water column when the water flow rate is small, and output a reciprocating fan-shaped water mist when the water flow rate is large, thereby increasing the floor washing range, and by swinging, while spraying and washing the ground, the surface garbage is swept to one side, which is easy to clean, thereby improving the cleaning efficiency and practicality of the floor scrubber.

[0021] In the present invention, a quick and stable connection between the nozzle and the water pipe is achieved by setting a connection expansion mechanism. When the connection shell rotates, the expansion shell is pressed down, the sealing ring expands, and fits tightly to the inner wall of the connection sleeve, thereby increasing the friction and sealing of the connection, improving the stability and waterproof effect of the connection, and facilitating quick assembly and disassembly of the nozzle and the pipeline.

[0040] The water pressure follower mechanism 2 includes a water flow baffle 21, which is fixedly connected to the inner surface of the nozzle housing 1, and the inner surface of the nozzle housing 1 is rotatably connected to a water wheel shaft 22, and both ends of the water wheel shaft 22 are fixedly connected to impact water wheels 221, and the outer surface of the impact water wheel 221 is provided with a wheel engaging groove 2211, and the inner surface of the nozzle housing 1 is slidably connected to a wheel limiting block 23, and the outer surface of the wheel limiting block 23 is fixedly connected to a wheel groove block 231, and the bottom surface of the wheel limiting block 23 is fixedly connected to a block limiting column 232, and the outer surface of the block limiting column 232 is sleeved with a block spring 233, and the outer surface of the water wheel shaft 22 is fixedly connected to an eccentric wheel 24, and the outer surface of the eccentric wheel 24 is slidably connected to a wheel sleeve 241, and the top of the wheel sleeve 241 is fixedly connected to the outer surface of the wheel sleeve 241. A vertical follower rod 25 is fixedly connected to the surface of the top of the vertical follower rod 25, a sleeve block 251 is fixedly connected to the top surface of the vertical follower rod 25, a sliding connection shaft 26 is slidably connected to the inner surface of the sleeve block 251, one end of the sliding connection shaft 26 is fixedly connected to a rotating column 261, the other end of the rotating column 261 is fixedly connected to a swing rod 262, and the outer surface of the rotating column 261 is fixedly connected to a column mounting bracket 27. Through the setting of the water pressure follower mechanism 2, during use, after the water flow enters the nozzle housing 1, it will continue to be input to the water pressure follower mechanism 2 and the follower deformation mechanism 3 along the inner wall. When passing through the nozzle housing 1, if the water flow is large, the wheel limit blocks 23 on both sides of the nozzle housing 1 will impact and press down to both sides, and the wheel limit blocks 23 will be connected with the wheel groove blocks 231 on the surface. The wheel engaging groove 2211 on the impact water wheel 221 is meshed, and when in contact, the impact water wheel 221 will be stuck to prevent it from rotating. After the wheel limit block 23 is pressed down, if the water flow decreases, it will bounce up again under the action of the block spring 233 to stick the impact water wheel 221. If the impact water wheel 221 is not stuck, the water flow will be blocked by the water flow baffle 21 on one side when passing through, and the water flow can only flow through the lower half of the impact water wheel 221, continuously impacting the impact water wheel 221 to make it rotate, and the impact water wheels 221 on both sides drive the middle water wheel shaft 22 to rotate. An eccentric wheel 24 is fixed on the surface of the water wheel shaft 22, and the connection between the water wheel shaft 22 and the eccentric wheel 24 is not more than the center of the eccentric wheel 24, so that the eccentric wheel 24 is regarded as a cam at this time. Since it is circular with the wheel sleeve 241, the wheel sleeve 241 It does not rotate itself, but will move vertically and horizontally following the rotation of the eccentric wheel 24, and will continuously drive the vertical follower rod 25 to make vertical reciprocating movement.

The connection between the nozzle housing 1 and the vertical follower rod 25 also allows the vertical follower rod 25 to move horizontally. During the vertical movement of the vertical follower rod 25, the top sleeve block 251 is sleeved on the surface of the sliding connection shaft 26, which will push the sliding connection shaft 26 to move back and forth. Due to the eccentricity of the eccentric wheel 24, the vertical follower rod 25 will also move horizontally, and the sleeve block 251 can also slide on the sliding connection shaft 26 to adapt to the lateral movement. The sliding connection shaft 26 will be continuously lifted and lowered, causing the rotating column 261 connected thereto to rotate back and forth.The reciprocating rotation is output to the swing rod 262 at the other end, so that it swings back and forth. The swing rod 262 is supported by the column mounting frame 27 and rotates inside, realizing the swing effect on the plane perpendicular to the water flow direction triggered according to the size of the water flow.

The symmetrical wheel limiting blocks 23 are used to simultaneously clamp the impact water wheels 221 on both sides. The clamping block spring 233 plays the role of resetting the wheel limiting block 23 while also limiting the reset wheel limiting block 23 on the nozzle housing 1 to prevent it from falling. The vertical driven rod 25 extends to the outside of the nozzle housing 1 to output reciprocating direct motion. The sleeve block 251 can slide and rotate on the sliding connection shaft 26 to adapt to the moving path of the vertical driven rod 25. The column mounting frame 27 is installed on the top of the nozzle housing 1 to set the installation height of the rotating column 261.

Through the setting of the follow-up deformation mechanism 3, during use, the rotating shell 31 can rotate on the nozzle shell 1, and during the rotation process, the rotating connecting ring 32 on the rotating shell 31 can be embedded in the rotating connecting groove 33 on the nozzle shell 1. When the distance between the rotating connecting ring 32 and the rotating connecting groove 33 becomes larger, the connecting pad 321 will be unfolded to cover the gap. When the distance is reduced, it will be rolled up in the rotating connecting groove 33, and the rotating connecting ring 32 and the rotating connecting groove 33 will also be blocked by the nozzle shell 1 on both sides, so as to ensure that the rotating shell 31 still maintains a seal with the nozzle shell 1 when rotating, and the swing rod 262 swings back and forth , the rotating input disk 34 will be continuously lifted and lowered by the rotating connecting rod 341 to realize the reciprocating rotation of the rotating input disk 34, and the rotating input disk 34 passes through the rotating connection between the nozzle housing 1 and the rotating housing 31 and is fixedly connected thereto to realize the reciprocating rotation of the rotating housing 31. In this way, when the water flows through, if the water flow is large, the rotating housing 31 will swing back and forth, and the moving platform 35 can slide up and down in the rotating housing 31. Since the top is pulled by the traction rope 36, the length of the traction rope 36 is fixed. When the rotating housing 31 is vertically downward, the traction rope 36 is tightened, and the moving platform 35 is at the lowest point on the rotating housing 31. When the rotating housing 31 is transferred to both sides, compared with the vertical state, the moving platform 35 is farther away from the rope positioning block 361 at this time.The traction rope 36 will pull the moving platform 35, and the moving platform 35 will move upward on the rotating shell 31 at this time, and when it rotates to the vertical state again, the push-out spring 372 installed on the outer mounting plate 37 will retreat to the lowest position again, so that the moving platform 35 follows the swing of the rotating shell 31 and moves up and down inside it. During the up and down movement of the rotating shell 31, the hinged rod 3521 is installed on both sides through the rotating connecting shaft 352, and the driven push-pull seat 3522 can only move horizontally in the push seat sliding groove 3523 through the path limit block 35221 at the bottom. When the movable housing 31 moves downward, the included angle increases and pushes the driven push-pull seat 3522 to both sides. When the rotating housing 31 moves upward, the included angle of the hinged rod 3521 decreases and the driven push-pull seat 3522 is pulled back on both sides. When moving outward at the same time, the elastic water outlet 353 is pulled open by the deformed push-pull column 35222, so that the two sides of the outlet become longer and narrower, and the original straight-type water column is converted into a fan-shaped water mist. According to the size of the water flow, a straight water column is output when the water flow is small, and a reciprocating swinging fan-shaped water mist is output when the water flow is large, thereby increasing the washing range, and by swinging, while spraying and washing the ground, the surface garbage is swept to one side for easy cleaning.

[0043] There are two rotating connecting rings 32, and the two rotating shells 31 are symmetrically distributed with the central axis of the rotating shell 31 as the symmetry axis.

The rotating connecting ring 32 and the connecting pad 321 are both slidably connected to the inner surface of the rotating connecting groove 33. The top surface of the rotating connecting rod 341 is rotatably connected to the swing rod 262. The moving platform 35 and the driven push-pull seat 3522 are both slidably connected to the inner surface of the shell through the groove 311. The path limit block 35221 is slidably connected to the inner surface of the push seat sliding groove 3523. The deformation push-pull column 35222 is fixedly connected to the outer surface of the elastic water outlet 353. The traction rope 36 passes through the rope positioning block 361, and the other end of the traction rope 36 is fixedly connected to the moving platform 35. The push-out mounting column 371 passes through the moving platform 35 and is slidably connected to its inner wall. The two ends of the push-out spring 372 are respectively connected to the top surface of the moving platform 35 and the bottom of the outer mounting plate 37 The surface is fixedly connected, and the rotating connecting ring 32, the connecting pad 321, and the rotating connecting groove 33 are symmetrically arranged to adapt to the swinging of both sides of the rotating shell 31. The rotating connecting ring 32 and the connecting pad 321 are inserted into the rotating connecting groove 33. When rotating, one side is retracted and the other side is unfolded to ensure the sealing of the rotating connection. The rotating connecting rod 341 transmits the reciprocating rotation of the swing rod 262 to the rotating shell 31 through the rotating input disk 34 to make it swing back and forth. The distance between the moving platform 35 and the driven push-pull seat 3522 increases when they are pressed down and extended outward. The shell is opened through the groove 311 to provide deformation space. The push seat sliding groove 3523 limits the path limit block 35221 so that it can only move in a straight line. The deformation push-pull column 35222 controls the bottom opening shape of the elastic water outlet 353 by pulling and squeezing. The traction rope 36 makes the distance between the moving platform 35 and the rope positioning block 361 always consistent. According to the swing of the rotating shell 31 and the joint action of the push spring 372, the position of the moving platform 35 on the rotating shell 31 is automatically adjusted.

[0044] The connecting expansion mechanism 4 includes a vertical path block 41, which is fixedly connected to the outer surface of the connecting shell 11, and the outer surface of the vertical path block 41 is slidably connected to the expansion shell 42, and the outer surface of the expansion shell 42 is sleeved with a sealing ring 43. The outer surface of the connecting shell 11 is provided with a threaded connection groove A44, and the outer surface of the connecting shell 11 is slidably connected to a connecting sleeve 45, and the bottom surface of the connecting sleeve 45 is provided with a path embedding groove 46, and the inner surface of the connecting sleeve 45 is provided with a threaded connection groove B47. Through the setting of the connecting expansion mechanism 4, during use, the connecting sleeve 45 is fixed on the water pipe of the input water flow, and when the nozzle needs to be installed, the connecting shell 1 is connected. 1 Align the connecting sleeve 45 and insert it into the inside until the threaded connecting groove A44 contacts the threaded connecting groove B47. At this time, the connecting shell 11 is rotated, and the connecting sleeve 45 will gradually move to the bottom of the connecting shell 11 and press down the expansion shell 42. The vertical path block 41 is located inside the path embedding groove 46 of the connecting sleeve 45 during connection. The expansion shell 42 moves on the vertical path block 41 and gradually moves outward with the downward pressure, and pulls the sealing ring 43 in four directions at the same time to expand it, so as to fit closely to the inner wall of the connecting sleeve 45, increase the friction at the connection to keep the connection stable, and use the expansion of the sealing ring 43 to improve the waterproof effect, so as to achieve the effect of quick assembly and disassembly and increase the friction and sealing at the connection.

[0045] There are four vertical path blocks 41, and the four vertical path blocks 41 are distributed in a ring around the connecting shell 11. There are four expansion shells 42, and the four expansion shells 42 are distributed in a ring around the connecting shell 11. The connecting sleeve 45 is slidingly connected to the outer surface of the expansion shell 42, and the vertical path block 41 is slidingly connected to the inner surface of the path embedding groove 46. The connecting shell 11 and the connecting sleeve 45 are threadedly connected through the threaded connection groove A44 and the threaded connection groove B47. The vertical path block 41 uses the expansion shell 42 to pull the sealing ring 43 outward from four directions to increase the contact area with the sealing ring 43 as much as possible and disperse the force. When in use, the vertical path block 41 is located inside the path embedding groove 46 without affecting other structures.

[0046] In this embodiment, Figure 1 As shown, the nozzle housing 1 is the outer shell part of the entire nozzle, which is used to install and protect the internal components, and the connecting housing 11 is used to connect with the connecting expansion mechanism 4 and is connected with the external pipeline;

[0047] In this embodiment, Figure 2 , Figure 3 , Figure 4 As shown, after the water flows into the nozzle housing 1, it will continue to be input to the water pressure follower mechanism 2 along the inner wall, and impact the impact water wheel 221 according to the size of the water flow to achieve rotation, and the wheel limit block 23 unlocks the rotation of the impact water wheel 221 according to the size of the water flow;

[0048] In this embodiment, Figure 5 , Figure 6 As shown, the impact water wheel 221 drives the eccentric wheel 24 to rotate through the middle water wheel shaft 22, and the wheel sleeve 241 moves vertically and horizontally following the rotation of the eccentric wheel 24, continuously driving the vertical driven rod 25 to make vertical reciprocating movements, which are transmitted to the rotating connecting rod 341 through the sliding connecting shaft 26 and the swing rod 262 to trigger the rotation of the rotating input disk 34;

[0049] In this embodiment, Figure 7 As shown, the rotating housing 31 can rotate on the nozzle housing 1;

[0050] In this embodiment, Figure 8 As shown, when the rotating housing 31 is transferred to both sides, the traction rope 36 will pull the mobile platform 35, and the mobile platform 35 will move upward on the rotating housing 31;

[0051] In this embodiment, Fig. 9 As shown, the rotating connecting ring 32 on the rotating housing 31 can be embedded in the rotating connecting groove 33 on the nozzle housing 1. When the distance between the rotating connecting ring 32 and the rotating connecting groove 33 increases, the connecting pad 321 will be unfolded to cover the gap. When the distance decreases, it will be rolled up in the rotating connecting groove 33, and the rotating connecting ring 32 and the two sides of the rotating connecting groove 33 will also be blocked by the nozzle housing 1, so as to ensure that the rotating housing 31 still maintains a seal at the connection with the nozzle housing 1 when rotating;

[0052] In this embodiment, Fig.10 , Fig.11 , Fig.12 As shown, during the up and down movement of the rotating housing 31, the two sides push and pull the driven push-pull seat 3522 through the rotating connecting shaft 352 through the hinge rod 3521, and when moving outward at the same time, the elastic water outlet 353 is pulled open through the deformation push-pull column 35222, so that the two sides of the outlet become longer and narrower, and the original straight-type water column is converted into a fan-shaped water mist;

[0053] In this embodiment, Fig.14 As shown, the vertical path block 41 uses the expansion shell 42 to pull the sealing ring 43 outward from four directions to increase the contact surface with the sealing ring 43 as much as possible and disperse the force;

[0054] In this embodiment, Fig.13 , Fig.15 As shown, align the connecting shell 11 with the connecting sleeve 45 and insert it into the interior until the threaded connecting groove A44 contacts the threaded connecting groove B47. At this time, rotate the connecting shell 11, and the connecting sleeve 45 will gradually move to the bottom of the connecting shell 11 and press the expansion shell 42 down.

[0055] A method for using a flush nozzle for a floor scrubber comprises the following steps:

[0056] S1. The connecting sleeve 45 is fixed on the water pipe for inputting water flow. When the nozzle needs to be installed, the connecting shell 11 is aligned with the connecting sleeve 45 and inserted into the inside, and the connecting sleeve 45 is threadedly connected through the threaded connection groove A44 and the threaded connection groove B47. When the threaded connection is rotated, the connecting sleeve 45 will gradually move to the bottom of the connecting shell 11, and the expansion shell 42 will be pressed down. The expansion shell 42 moves on the vertical path block 41, and will gradually move outward with the downward pressure, and pull the sealing ring 43 in four directions at the same time to expand it, so as to be close to the inner wall of the connecting sleeve 45, increase the friction at the connection and keep the connection stable;

[0057] S2, the wheel limit block 23 is meshed with the wheel engaging groove 2211 on the impact water wheel 221 through the wheel groove block 231 on the surface. When the water flows through the nozzle housing 1, if the water flow is large, the wheel limit blocks 23 on both sides of the nozzle housing 1 will impact and press down to both sides. At this time, the wheel limit block 23 is no longer in contact with the impact water wheel 221. When the water flows through, one side is blocked by the water flow baffle 21, and the water can only flow through the lower half of the impact water wheel 221, continuously impacting the impact water wheel 221 to make it rotate. When the water flow decreases, the wheel limit block 23 will bounce up again under the action of the block spring 233 to clamp the impact water wheel 221;

[0058] S3, the impact water wheel 221 drives the eccentric wheel 24 to rotate through the middle water wheel shaft 22, and the wheel sleeve 241 moves vertically and horizontally following the rotation of the eccentric wheel 24, continuously driving the vertical driven rod 25 to make vertical reciprocating movements, and the top sleeve block 251 sleeves on the surface of the sliding connection shaft 26, which will push the sliding connection shaft 26 to move back and forth. The sliding connection shaft 26 will be continuously lifted and lowered, so that the rotating column 261 connected to it reciprocates, and the reciprocating rotation is output to the swing rod 262 at the other end, so that it swings back and forth;

[0059] S4, the swing rod 262 continuously lifts and lowers the rotating input disk 34 by rotating the connecting rod 341, so as to realize the reciprocating rotation of the rotating shell 31. When the rotating shell 31 is vertically downward, the traction rope 36 is tightened, and the moving platform 35 is pushed out by the pushing spring 372 installed on the outer mounting plate 37 to the lowest point on the rotating shell 31. When the rotating shell 31 is transferred to both sides, the traction rope 36 will pull the moving platform 35. At this time, the moving platform 35 will move upward on the rotating shell 31. In the process of the rotating shell 31 moving up and down, the two sides push and pull the driven push-pull seat 3522 through the hinge rod 3521 through the rotating connecting shaft 352. When moving outward at the same time, the elastic water outlet 353 is pulled open by the deformation push-pull column 35222, so that the two sides of the outlet become longer and narrower, and the original straight-flushing water column is converted into a fan-shaped water mist. When moving inside the box, the elastic water outlet 353 is pushed, pulled and restored inside the box.

5. The method for using the flushing nozzle for a floor scrubber according to claim 1 comprises the following steps: S1. The connecting sleeve (45) is fixed on the water pipe for inputting water flow. When the nozzle needs to be installed, the connecting housing (11) is aligned with the connecting sleeve (45) and inserted into the inside. The connecting sleeve (45) is threadedly connected through the threaded connection groove A (44) and the threaded connection groove B (47). When the threaded connection is rotated, the connecting sleeve (45) gradually moves to the bottom of the connecting housing (11), pressing the expansion housing (42) down. The expansion housing (42) moves on the vertical path block (41), gradually moves outward with the downward pressure, and pulls the sealing ring (43) in four directions at the same time to expand it, thereby clinging to the inner wall of the connecting sleeve (45), increasing the friction at the connection to keep the connection stable; S2, the wheel limit block (23) is meshed with the wheel engagement groove (2211) on the impact water wheel (221) through the wheel groove block (231) on the surface. When the water flows through the nozzle housing (1), if the water flow is strong, the wheel limit blocks (23) on both sides of the nozzle housing (1) will impact and press down to both sides. At this time, the wheel limit block (23) is no longer in contact with the impact water wheel (221). When the water flows through, one side is blocked by the water flow baffle (21). The water flow can only flow through the lower half of the impact water wheel (221), continuously impacting the impact water wheel (221) to make it rotate. When the water flow decreases, the wheel limit block (23) will bounce up again under the action of the block spring (233) to clamp the impact water wheel (221); S3, the impact water wheel (221) drives the eccentric wheel (24) to rotate through the middle water wheel shaft (22), and the wheel sleeve (241) moves vertically and horizontally following the rotation of the eccentric wheel (24), continuously driving the vertical driven rod (25) to make vertical reciprocating movements, and the top sleeve block (251) sleeves on the surface of the sliding connection shaft (26), which will push the sliding connection shaft (26) to move back and forth. The sliding connection shaft (26) will be continuously lifted and lowered, causing the rotating column (261) connected thereto to reciprocate, and the reciprocating rotation is output to the swing rod (262) at the other end, causing it to swing back and forth; S4, the swing rod (262) continuously lifts and lowers the rotating input disk (34) by rotating the connecting rod (341), thereby realizing the reciprocating rotation of the rotating housing (31). When the rotating housing (31) is vertically downward, the traction rope (36) is tightened, and the mobile platform (35) is pushed out by the push-out spring (372) installed on the outer mounting plate (37) to the lowest point on the rotating housing (31). When the rotating housing (31) moves to both sides, the traction rope (36) will pull the mobile platform (35). The movable platform (35) moves upward on the rotating shell (31). During the upward and downward movement of the rotating shell (31), the two sides push and pull the driven push-pull seat (3522) through the hinge rod (3521) by the rotating connecting shaft (352). When moving outward at the same time, the elastic water outlet (353) is pulled open by the deformable push-pull column (35222), so that the two sides of the outlet become longer and narrower, and the original straight-type water column is converted into a fan-shaped water mist. When moving inside the box, the elastic water outlet (353) is pushed and pulled and restored inside the box.
