The inlet pipe 13 also includes a sealing structure, preferably a sealing ring, between the inlet pipe 13 and the outlet 64. However, the present invention is not limited to this, and other sealing structures may be used.

The brush head 12 is configured by the connection assembly 11 to be rotatable about a first axis of rotation and a second axis of rotation, the second axis of rotation extending in the direction of the inlet pipe 13, the direction of extension of the first axis of rotation and the direction of extension of the second axis of rotation being angularly disposed. The first axes of rotation may lie in the same plane and may be disposed out of plane. When the first rotation axis and the second rotation axis are located in the same plane, the angle between the extending direction of the first rotation axis and the extending direction of the second rotation axis refers to the angle formed by the intersection or the intersection after the intersection is prolonged. When the first rotation axis and the second rotation axis are arranged in a non-coplanar manner, the angle between the extending direction of the first rotation axis and the extending direction of the second rotation axis refers to an angle formed by the intersection after the two rotation axes move to the same plane or the intersection after the two rotation axes extend. The first rotation axis and the second rotation axis are only used for describing the rotation relationship, and have no relationship with the shapes of the water inlet pipe, the connecting assembly and the brush head shell, and the three can be in any shapes. The water-driven brush can rotate around the first rotation axis and the second rotation axis, so that the cleaning plane of the cleaning brush can rotate to any position in an omnibearing manner to meet the requirements of users. Preferably, the angle between the extension of the first axis of rotation and the extension of the second axis of rotation is 60-90 degrees.

In the present embodiment, the angle between the extending direction of the first rotation axis and the extending direction of the second rotation axis is 90 degrees, and the first rotation axis and the second rotation axis are located in the same plane.

The connecting assembly 11 comprises a connecting bracket 1101, the connecting bracket 1101 comprises a second mounting end 112 rotatably connected with the water inlet pipe 13, and the connecting bracket 1101 drives the brush head 12 to rotate relative to the water inlet pipe 13 to realize rotation of a second rotation axis. In order to reduce the weight of the cleaning machine, the connecting bracket 1101 is preferably a housing structure.

Horizontal placement of the cleaning brush 14 as shown in figure 2, the brush head 12 is in an initial position. The brush head 12 is capable of 360 degrees of left or right rotation about the second axis of rotation. The left-right direction refers to a left-right direction when the user holds the handle 61, and in this application, the second rotation axis coincides with the axis of the water inlet pipe 13. Specifically, the connecting bracket 1101 can be rotated to the left and right by the same angle about the axis of the inlet pipe 13. More specifically, the connecting bracket 1101 can be rotated by the same angle in each of the left and right directions about the axis of the inlet pipe 13 in the range of 0 to 180 degrees, preferably in the range of 20, 30, 40, 50, 60, 70, 80, 100, 120, 180 degrees. The brush head 12 is configured to rotate around the axis of the water inlet pipe 13 by the same angle in the left-right direction, so that when the cleaning machine 100 is used for cleaning, the brush head 12 rotates by the same angle in the left-right direction, that is, the flexibility of left-right cleaning is the same, and different surfaces to be cleaned on the left side and the right side can be cleaned conveniently. That is, the user can change the left hand and the right hand according to the operation habit to conveniently brush the cleaning objects on the left side and the right side of the body, so that the cleaning machine 100 rotates leftwards or rightwards, and the cleaning angle is more convenient to adjust. Meanwhile, when the surface to be cleaned is a curved surface, the brush head 12 rotates around the axis of the water inlet pipe 13 in the process of moving along the curved surface, the cleaning brush 14 is attached to the surface to be cleaned to the greatest extent all the time while the handheld action of a user is not changed, the operation is simple, and the cleaning efficiency is improved. Preferably, the connecting bracket 1101 can rotate by 90 degrees to the left and right around the axis of the inlet pipe 13. The cleaning brush 14 is rotated by 90 degrees to the left or right so that the cleaning plane of the cleaning brush 14 is rotated to a vertical plane, so that the cleaning brush 14 can brush the vertical wall surfaces on the left and right sides without changing the posture of the hand holding the washing machine 100, thereby facilitating the operation of the user.

Of course, the connecting bracket 1101 may be provided so as to be rotated by different angles in the left-right direction about the axis of the inlet pipe 13, or the connecting bracket 1101 may be provided so as to be rotated only by a set angle in the left-right direction. Since the right-handed operation of the washing machine 100 is used to rotate the cleaning brush 14 to the right, which is usually the right-handed person, to facilitate washing of the surface of the object to be washed, the right rotation of the cleaning brush 14 is more ergonomic for most right-handed users.

The second mounting end of the connecting bracket 1101 is a hollow structure, the connecting bracket 1101 is sleeved on the water inlet pipe 13 through the second mounting end 112, and the connecting bracket 1101 and the water inlet pipe 13 are rotatably mounted to realize the rotating mounting of the brush head and the water inlet pipe. A sealing structure, which may be a sealing ring, is also provided between the connecting bracket 1101 and the water inlet pipe 13.

The connecting bracket 1101 further includes a first mounting end 111 connected to the head 12, and the head 12 rotates relative to the connecting bracket 1101 to effect rotation of the head 12 about a first axis of rotation. The brush head 12 rotates up and down about the first axis of rotation to change the angle a between the cleaning plane of the hydrodynamic brush 10 and the inlet conduit as shown in fig. 4 to adjust the angle of the cleaning plane for easier user operation. For example, when the wall surface at a higher position needs to be cleaned, the angle between the water inlet pipe 13 and the cleaning plane of the brush head 12 can be adjusted to 0, so that the cleaning brush 14 reaches the farthest height, and when the floor near the feet needs to be cleaned, the angle between the water inlet pipe 13 and the cleaning plane of the brush head 12 is set as shown in fig. 4, so that the user can keep a standing posture for cleaning without bending down, and the labor intensity is reduced. The ability of the head 12 to rotate about the first axis of rotation should be understood to mean that from the position shown in figure 2 the head 12 rotates upwardly towards the side facing away from the cleaning brush 14 or the head 12 rotates downwardly towards the side adjacent to the cleaning brush 14, the cleaning angle being adjusted in two dimensions, the angle of application of force by the user being adjustable, making the use of the water driven brush 10 more flexible.

The brush head 12 may be configured to rotate up and down the same angle, which may range from 0-90 degrees, preferably between 0-60 degrees. In addition, depending on the user's usage habits, it is preferred that the brush head 12 be rotated upward toward the side away from the cleaning brush 14, as shown in FIG. 4, because this rotation pattern allows the cleaning surface to be fully exposed and facilitates the user's exertion.

The brush head shell 1201 is provided with a bulge 122, and the first mounting end 111 is rotatably mounted with the bulge 122. Specifically, an outer annular groove and an outer guide groove connected to the outer annular groove are formed on the outer side wall of the protrusion 122. The first installation end 111 of linking bridge 1101 establishes the mounting groove with protruding 122 adaptation, and the mounting groove inner wall is equipped with installation arch 1132, and installation arch 1132 gets into outer annular groove through outer guide way, and at this moment, protruding 122 is located the mounting groove, and the installation arch 1132 can slide in the annular groove and realize linking bridge 1101 and brush head 12's rotation installation.

A first angle limiting structure is arranged between the connecting bracket 1101 and the brush head 12 for limiting the rotation angle between the connecting bracket 1101 and the brush head. In this embodiment, the first angle limiting structure is a circumferential groove 128 formed on the protrusion 122, at least a portion of the connecting assembly 11 always moves in the circumferential groove 128, and the rotation angle is defined by the contact between at least a portion of the connecting assembly 11 and two opposite sides of the circumferential groove 128.

The brush head 12 can rotate relative to the connecting bracket 1101 in a stepless manner within the range defined by the first angle limiting structure, and can stay at any angle within the range defined by the first angle limiting structure. In this embodiment, the circumferential groove 128 limits the brush head 12 from 0 to 90 degrees of rotation relative to the connecting bracket 1101. Preferably, the circumferential groove 128 limits the rotation of the head 12 to the side away from the brush 14, as shown in FIG. 4, by an angle a between 0 and 90 degrees. Preferably, the angle a is between 0 and 60. In addition, the arrangement of the circumferential groove 128 also enables the connecting bracket 1101 to be closer to the center of the brush head 12, so that the structure is more compact.

When a user rotates the connecting bracket 1101 and the brush head 12 to an optimal angle for cleaning, the user often applies force to the brush head 12 to increase the cleaning capability, but the angle of the force cannot be controlled, so that the connecting bracket 1101 and the brush head 12 are easy to rotate again, the optimal angle adjusted between damage is damaged, and the use experience of the user is influenced.

In this embodiment, the coupling assembly 11 further includes a twist-on structure 16 that defines the rotational fixation of the head 12 at a plurality of predetermined angles. Specifically, the cinch structure 16 is located between the first mounting end 111 and the head 12.

Referring to fig. 13, the tightening structure 16 includes a first tooth structure 1601 disposed on the brush head housing 1201, a second tooth structure 1602 disposed to cooperate with the first tooth structure 1601 at the first mounting end 111, and a knob 1603 for tightening or loosening the first tooth structure 1601 and the second tooth structure 1602. The knob 1603 loosens the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602, and the connecting assembly 11 can rotate in an electrodeless way relative to the brush head 12; knob 1603 is tightened to engage first and

second tooth structures

1601, 1602, and the angle of rotation between coupling assembly 11 and head 12 is a predetermined angle defined by the engagement of first and

second tooth structures

1601, 1602.

Two types of situations are involved in screwing the first tooth structure 1601 and the second tooth structure 1602. One of them is that the tooth form of the first tooth form structure 1601 and the tooth form of the second tooth form structure 1602 are in a non-meshing position, and at this time, the first tooth form structure 1601 and the second tooth form structure 1602 rotate, and continue to move relatively along the tooth form until the tooth form meshes and is fastened with each other, that is, in the process of screwing the knob 1603, the connection bracket 1101 and the brush head 12 are driven by the first tooth form structure 1601 and the second tooth form structure 1602 to rotate. In another case, the tooth form of the first tooth form structure 1601 and the tooth form of the second tooth form structure 1602 are in a meshing position, and when the first tooth form structure 1601 and the second tooth form structure 1602 rotate, the first tooth form structure 1601 and the second tooth form structure 1602 are tightly connected, and when the knob 1603 is tightened, the connection bracket 1101 and the brush head 12 do not rotate, the tightening structure 16 can limit a rotation angle of the brush head 12 relative to the connection bracket 1101, where the rotation angle is a preset angle determined by the meshing position of the first tooth form structure 1601 and the second tooth form structure 1602. Preferably, the preset angle is an arithmetic progression. In this embodiment, the preset angle is an arithmetic progression with an interval of 10 degrees, and the preset angles are 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, etc., respectively, but the preset angle may be other regularly arranged progression or irregularly arranged progression.

The tightening mechanism 16 has a free state not selected for use and an operating state selected for use. The tightening mechanism 16 is in a free state, which should be understood as: without the use of the tightening structure 16, the first tooth structure 1601 and the second tooth structure 1602 are loosely disposed so that the connecting assembly 11 rotates endlessly with respect to the head 12. The tightening mechanism 16 is in an operating state, which should be understood as: the tightening structure 16 is applied, the knob 1603 is used for loosening the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 to realize that the connecting assembly 11 rotates relative to the brush head 12, the knob 1603 is used for screwing the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 to enable the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 to be meshed, the connecting assembly 11 and the brush head 12 are stably fixed at a preset angle, and the knob 1603 is tightened to enable the rotating angle of the connecting assembly 11 and the brush head 12 to be only a preset angle limited by the meshed tooth shapes. The user can better use the water driven brush 10 for cleaning without concern for forcibly rotating the brush head 12 of the water powered brush to destroy the set cleaning angle.

The water driven brush 10 has a selectable stepless rotation mode, a defined rotation mode. When the water driven brush 10 is in the stepless rotation mode, the tightening structure 16 is in a free state, and the connecting assembly 11 can rotate in a stepless manner by 0 to 360 degrees relative to the brush head 12, or the angle of rotation of the connecting assembly 11 relative to the brush head 12 can be limited by the first limiting structure, for example, in the present application, by the circumferential groove 128. When the water driven brush 10 is in a limited rotation mode, the tightening structure 16 is in an operating state, and the connecting assembly 11 can rotate relative to the brush head 12 within a limited preset angle.

The user can choose to use the electrodeless rotation mode to adjust the brush head 12 at will, stops at any angle, rotates in a flexible way, also can choose to limit the rotation mode, rotates the brush head 12 and fixes on the preset angle, operates more stably, avoids the cleaning process, and the brush head 12 rotates, and the regulation that the brush head 12 can be diversified, and user's selection is more, and man-machine is better.

In this embodiment, the tooth shapes of the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 are both located on a plane and arranged around a center of a circle, the centers of the circle of the first tooth-shaped structure 1601 and the circle of the second tooth-shaped structure 1602 are on the same straight line after installation, the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 rotate around the center of a circle to relatively move and change the meshing position, and the knob 1603 changes the distance between the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 by changing the position of the center of a circle, so as to control the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602 to loosen and fasten. Preferably, the centers of both are located on the axis of the knob 1603.

Tightening the knob 1603 presses the handle 1623 against the second toothed structure 1602, compressing the second toothed structure 1602 and the first toothed structure 1601 to secure them. In the present application, the connection shaft 1613 is threadedly coupled to the first toothed structure 1601 such that turning the knob 1623 can loosen or tighten the second toothed structure 1602 and the first toothed structure 1601.

The tightening mechanism 16 further includes a resilient structure that assists the tightening mechanism 16 in maintaining a free state, and when the knob-releasing tightening mechanism is in the free state, the resilient structure applies a force to the first tooth-shaped structure and the second tooth-shaped structure to keep them disengaged. In this embodiment, the elastic structure is a spring 1604 located between the torsion bar 1623 and the first toothed structure 1601, when the knob 1603 is unscrewed, the spring 1604 moves the torsion bar 1623 in a direction away from the first toothed structure 1601, and the torsion bar 1623 releases the first toothed structure 1601 and the second toothed structure 1602, and maintains the released state, which assists the tightening structure 16 in a free state.

The tightening mechanism 16 also includes a second angular limit that defines a range of preset angles of rotation of the head 12 and the connecting bracket 1101. The second angular limit structure is only active when the water driven brush 10 is in the limited rotation mode, and when the water driven brush 10 is in the stepless rotation mode, the brush head 12 rotates steplessly within the range limited by the first angular limit structure.

Preferably, the range defined by the second angle limiting structure is within the range defined by the first angle limiting structure, so that the preset angle within the range defined by the second angle limiting structure can be realized. In this embodiment, the range defined by the second angle limiting structure is 0 to 60 degrees, when the tightening structure 16 works, the preset angles of the rotation of the connecting assembly 11 relative to the brush head 12 at the side of the brush head 12 away from the cleaning brush 14 are 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, and 60 degrees, and in this embodiment, when the tightening structure 16 works, the connecting assembly 11 rotates at the side of the brush head 12 away from the cleaning brush 14 by 10 degrees, 20 degrees, 30 degrees, 40 degrees, 50 degrees, and 60 degrees, and the preset angles can meet the requirement of the cleaning operation of the user. Specifically, the second angle limiting structure includes a limiting groove 162 located on one of the first tooth-shaped structure 1601 and the second tooth-shaped structure 1602, and a limiting protrusion 161 located on the other, when the water driven brush 10 is in the limited rotation mode, the limiting protrusion 161 is located in the limiting groove 162, the limiting protrusion 161 and the limiting groove 162 limit the range of the preset angle of rotation of the connecting assembly 11 and the brush head 12, and when the tightening structure 16 is in the stepless rotation mode, the limiting protrusion 161 and the limiting groove 162 are separated so as not to affect the angle of the stepless rotation.

In this application, the connecting bracket 1101 is Y-shaped, and includes a second mounting end 112 and two first mounting ends 111, the two first mounting ends 111 are rotatably connected to the brush head housing 1201, and the two first mounting ends 111 clamp the brush head 12 therebetween to limit the movement of the brush head 12 between the two first mounting ends 111. The connection structure between the two first mounting ends 111 and the head housing 1201 may be different and may be the same. In this application, a rotary connection structure of the mounting protrusion 1132 and the outer annular groove is adopted between one first mounting end 111 and the head housing 1201, and a rotary connection structure of the knob 1603 and the screw thread is adopted between the other first mounting end 111 and the head housing 1201. At this time, the first angle limiting structure and the second angle limiting structure are respectively arranged between the two first mounting ends 111 and the brush head shell 1201, so that mutual interference is avoided, and the structure is simpler.

The connection assembly 11 further includes a connection pipeline, the connection pipeline is communicated with the water inlet pipeline, and the fluid is sequentially injected onto the impeller 121 through the water inlet pipeline and the connection pipeline.

The brush head shell 1201 is further provided with a mounting opening 124, one end of the connecting pipe far away from the water inlet pipe is accommodated in the mounting opening 124, and the connecting pipe sprays water flow into the brush head 12 through the mounting opening 124 to drive the impeller 121 to drive the cleaning brush 14 to work.

The rotational speed of the cleaning brush 14 is within a certain range to achieve its desired effect, for example, to brush off dust accumulated by friction of the brush head, etc. Therefore, there is a certain requirement for the rotation speed of the impeller 121, so that the water flow from the water outlet of the nozzle 125 needs to have enough impact force to drive the impeller to have a certain rotation speed, and drive the cleaning brush 14 to ensure that the cleaning brush 14 achieves the desired effect.

The application of the conventional water-driven brush 10 is limited to be connected to a high-pressure water source, and the high-pressure water source can drive the impeller 121 to reach a corresponding rotating speed even though energy loss exists after entering the water-driven brush 10 and the high-pressure water source is sprayed out from the nozzle 125. When connected to a low pressure water source, which after a portion of the energy loss after entering the water-driven brush, has hardly hit the impeller 121 to rotate the impeller 121 or can only slowly rotate the impeller 121 at a very low rotational speed, only with a "scratchy boot" cleaning effect.

The water driven brush 10 of the present application, by limiting the size of the water jet of the nozzle 125, enables the water driven brush 10 to be adapted for use in connection with any source of water under pressure, including low and high pressures. After the water enters the water-driven brush and flows to the nozzle 125, after a round of energy loss, the water is accelerated in the water jet just before the water is sprayed out through the water jet with a certain number of apertures, so that the water can obtain enough energy to impact the impeller 121 to drive the impeller 121 to rotate. And the energy of the water flow accelerated by the water jet is not meaningfully lost and is directly sprayed and applied to the impeller 121. Of course, the diameter of the water jet is also related to the overall weight of the impeller 121, the size of the blades of the impeller 121, and the like.

In this application, a water driven brush 10 can be attached to the washer 100. The portable cleaning machine 100 is often limited in terms of its weight, both in terms of functional components and power source, resulting in a low nominal pressure and low flow rate characteristic of the emitted water flow. In all aspects, in this embodiment, the diameter of the water jet of the nozzle is 1-3mm, so that the nozzle can adapt to the low-pressure and low-flow characteristics of the portable cleaning machine 100, so that the jetted water can be jetted out at a higher speed through the small-diameter nozzle 125, and a certain flow is ensured, thereby more effectively driving the impeller 121 to rotate, and further driving the brush head 12 to work. The diameter of the water jet of the nozzle 125 can also be 1-2.5mm, ensuring that the impeller can have a certain rotational speed even if low-pressure water flow is connected.

Further, for the water-driven brush 10 of the present application to cooperate with the washing machine 100 to realize the washing function, the impeller 121 can rotate at a speed not less than 200 revolutions to achieve an ideal cleaning effect. The rotational speed of the impeller connected to the washer can also be between 200 and 300 when the cleaning machine is operating at the lowest power. Therefore, in order to ensure the rotation speed, the diameter of the water jet of the nozzle 125 of the present application is 1.8-2 mm. For example, in the case that the nominal value of the washing machine 100 is 2Mpa, the water flow is accelerated and sprayed out through the water spraying opening of the nozzle 125 after being sprayed out from the washing machine, and then the impeller 121 is driven to rotate, and the rotation speed is 200 revolutions and 300 revolutions, so that the cleaning function can be better realized.

In this embodiment, the mounting opening 124 extends through the protrusion 122. In this embodiment, referring to fig. 7, the connection pipe includes an outlet pipe 116 rotatably connected to the inlet pipe 13, and a nozzle joint 113 fixed to an end of the outlet pipe 116 far from the inlet pipe 13, the nozzle 125 is rotatably connected to the nozzle joint 113, and water flows to the nozzle joint 113 through the outlet pipe 116 and is sprayed out from the nozzle 125.

The outlet tube 116, part of the nozzle fitting 113, is housed within the housing structure of the connection bracket 1101. The nozzle adapter 113 is always within the circumferential groove 128, limiting the angle of rotation between the connecting bracket 1101 and the brush head 12.

And a sealing structure is arranged between the water inlet pipe 13 and the connecting pipeline 1302, so that water flow is prevented from flowing out, and the sealing property is enhanced. The connecting pipe 1302 and the connecting bracket 1101 are rotatably connected with the water inlet pipe 13, so that the connecting pipe 1302 and the connecting bracket 1101 can rotate around the water inlet pipe 13, and the brush head 12 can rotate around a second rotation axis, wherein the rotation angle range is greater than 0 degree and less than or equal to 360 degrees. And an axial limiting structure is arranged between the connecting bracket 1101 and the water inlet pipe so as to make the connecting bracket 1101 and the water inlet pipe 13 axially immovable, and the axial limiting structure can be any structure.

In this embodiment the nozzle connection 113 is a right angle connection which changes the flow of water from a tangential direction to the brush head 12 to a radial direction to the brush head 12. Of course, the nozzle joint 113 can be arranged as an acute angle joint, one end of the acute angle joint extends along the radial direction of the brush head 12, and the acute angle type nozzle joint 113 enables the nozzle joint 113 to be close to the side of the brush head 12, so that the water driven brush 10 is more compact and has small volume.

The height of the limiting protrusion 161 along the axial direction of the nozzle joint 113 is equal to the height of the inner annular groove along the axial direction of the water outlet pipe 116, so as to prevent the nozzle joint 113 from moving relative to the water outlet pipe 116 along the water flow direction, and thus, the limiting function is achieved.

The nozzle joint 113 is pivotally connected with the nozzle 125, and a sealing structure is arranged between the nozzle joint 113 and the nozzle 125 to prevent water leakage.

In order to prevent the reaction force of the sprayed water to the nozzle joint 113 and the nozzle 125 from disconnecting or loosening the nozzle joint 113 from the nozzle 125, so that the water is sprayed from the fracture or gap, and to prevent the nozzle 125 from rotating or moving in the mounting opening 124, a fixing structure is provided between the nozzle 125 and the mounting opening 124.

The fixed structure may be such that the nozzle 125 has at least two different cross-sectional areas and is smaller in the direction of fluid flow in the nozzle 125, i.e., the end near the nozzle adapter 113 has a larger diameter, the mounting opening 124 matches the shape of the nozzle 125, and when the nozzle 125 is mounted in the mounting opening 124, the brush head 12 and the nozzle adapter 113 hold the nozzle 125 therebetween to overcome the reaction force and keep the nozzle adapter 113 and the nozzle 125 connected to each other.

Preferably, the water flow is emitted along the radial direction of the impeller 121 in the extending direction of the nozzle 125 at an inclined angle of 45 degrees, that is, the water flow is emitted onto the impeller 121 in a tangential direction, so that the mechanical loss of the water flow emitted from the obliquely arranged nozzle 125 is reduced to the maximum extent, and the transmission efficiency is higher.
