[0073] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0074] Reference Figure 1-8 The nozzle 100 for high-pressure cleaning equipment includes: a connecting member 101, a water spraying member 102, a main shaft 103, a turbine blade member 104, a driving shaft 105, a passive shaft 106, a connecting group 107, and a separating group 108; the connecting member 101 is fixed on the water outlet of the water outlet pipe; the water spraying member 102 is rotatably connected to the connecting member 101 through a fixing member 109, the fixing member 109 is threadedly connected to the connecting member 101, the water spraying member 102 is rotatably connected to the fixing member 109, and a cavity 102a and a water spraying hole 102b are provided on the water spraying member 102; the main shaft 103 is fixed on the connecting member 101 and is located at the center of the connecting member 101; the turbine blade member 104 is rotatably sleeved on the main shaft 103, and the turbine blade member 104 is a fan, and an internal threaded ring 110 is provided above the fan, and the internal threaded ring 110 is threadedly connected to the main shaft 103 for limiting the upward movement of the fan.

[0075] The driving shaft 105 is rotatably arranged on the main shaft 103 and is coaxial with the main shaft 103. A through groove 103a is opened on the main shaft 103, and the driving shaft 105 slides up and down in the through groove 103a; the passive shaft 106 is fixed on the water spraying member 102 and is located above the driving shaft 105; the connecting group 107 is arranged on the driving shaft 105 and the passive shaft 106, and is used to connect the driving shaft 105 and the passive shaft 106, so that when the driving shaft 105 rotates, the passive shaft 106 is driven to rotate synchronously; the separating group 108 is arranged on the driving shaft 105, and is used to separate the driving shaft 105 from the passive shaft 106, so that the passive shaft 106 stops rotating.

[0076] During water spray cleaning, water flows into the connecting member 101 and the water spray member 102, the water drives the turbine blade member 104 to rotate, the turbine blade member 104 drives the driving shaft 105 to rotate, the driving shaft 105 drives the passive shaft 106 to rotate via the connecting group 107, and the passive shaft 106 drives the water spray member 102 to rotate, so that the water column discharged from the water spray hole 102b can clean the holes and other positions on the equipment in an all-round way.

[0077] When the water spraying member 102 is not required to rotate, the user can operate the separation group 108 to separate the driving shaft 105 from the driven shaft 106 , so that the driven shaft 106 stops rotating, thereby stopping the water spraying member 102 from rotating.

[0078] The spaces in the cavity 102a and the water spray hole 102b are both truncated cone-shaped. The cavity 102a is located at the center of the water spray member 102. The cavity 102a has only one opening, and the opening of the cavity 102a is located at one end of the water spray member 102 close to the connecting member 101. The diameter of the lower end of the cavity 102a is greater than the diameter of the upper end of the cavity 102a to accelerate the water flow speed; the water spray hole 102b horizontally surrounds the side wall of the water spray member 102, and the water spray hole 102b is connected to the cavity 102a.

[0079] The connection group 107 includes: a fixed sleeve 107a, a cog 107b, and a fixed ring 107c; ​​the fixed sleeve 107a is fixed to one end of the active shaft 105 close to the passive shaft 106, and the sleeve opening of the fixed sleeve 107a is located at one end of the fixed sleeve 107a close to the passive shaft 106, so that the passive shaft 106 can be inserted into the fixed sleeve 107a, which plays a role in rotation limitation; the cog 107b is integrally formed on the end face of one end of the sleeve opening on the fixed sleeve 107a, and the cog 107b is arranged in a circular array around the axis of the passive shaft 106; the fixed ring 107c is fixed to the passive shaft 106, and is located at the middle end of the passive shaft 106, and a groove 107d is provided on the end face of the fixed ring 107c facing the active shaft 105, in which the kung fu cog 107b is embedded.

[0080] The separation group 108 includes: an insertion rod 108a, a support seat 108b, a spring 108c, a pressure rod 108d, and a guide member 108e; the insertion rod 108a is fixed to the side walls on both sides of the driving shaft 105, the axis of the insertion rod 108a is perpendicular to the axis of the driving shaft 105, the lower end surface of the main shaft 103 abuts on the insertion rod 108a, the insertion rod 108a gives the main shaft 103 an upward support force, and the lower end surface of the turbine blade member 104 is provided with a card slot 104a for the insertion rod 108a to be embedded, so that when the turbine blade member 104 rotates, it drives the driving shaft 105 to rotate; the support seat 108b is fixed on one end of the connecting member 101 away from the water spraying member 102. The support seat 108b is located below the main shaft 103. A support shaft 111 is provided on the support seat 108b. The support shaft 111 is located directly below the driving shaft 105. A clearance groove 111a is provided on the upper end surface of the support shaft 111 to provide space for the insertion rod 108a to slide down. The clearance groove 111a penetrates both sides of the support shaft 111 along the radial direction of the support shaft 111. A socket 111b is provided on the support shaft 111 for the driving shaft 105 to slide down and be inserted, and the socket 111b is connected to the clearance groove 111a.

[0081] The spring 108c is placed in the socket 111b, below the driving shaft 105, and is used to support the driving shaft 105 upward; the pressure rod 108d is slidably arranged on the connecting member 101, and a part of the pressure rod 108d is located in the socket 111b, and the pressure rod 108d is between the spring 108c and the driving shaft 105; the guide member 108e is fixed on the support seat 108b, and a guide groove 108f is provided on the pressure rod 108d for the guide member 108e to pass through.

[0082] The spring 108c supports the pressure rod 108d upward, allowing the pressure rod 108d to lift the active shaft 105, so that the insertion rod 108a is embedded in the card slot 104a, and the cog 107b is embedded in the embedding slot 107d. The active shaft 105, the passive shaft 106 and the turbine blade member 104 are connected together, so that the rotation of the turbine blade member 104 drives the passive shaft 106 to rotate. When the water spraying member 102 is to stop rotating, the user slides the pressure rod 108d downward to allow the pressure rod 108d to compress the spring 108c, and the active shaft 105 moves downward due to gravity, driving the cog 107b to separate from the embedding slot 107d, canceling the transmission connection between the active shaft 105 and the passive shaft 106, and realizing the stopping of the water spraying member 102.

[0083] Magnets with opposite charges attract each other are installed at the contact point between the driving shaft 105 and the pressure rod 108d, so that even if the nozzle 100 for high-pressure cleaning equipment is in a horizontal or upside-down tilted state, the user can slide the pressure rod 108d toward the support seat 108b to drive the driving shaft 105 to move toward the support seat 108b, thereby separating the cog 107b from the cog groove 107d.

[0084] A flow guide 112 is fixed to the lower end of the support seat 108b. The lower end surface of the flow guide 112 is constructed to be a conical surface, forming a flow guide surface 112a. A flow guide groove 112b is formed on the flow guide surface 112a.

[0085] By disposing the guide surface 112 a and the guide groove 112 b , the guide surface 112 a diffuses the water flow outward, reduces the impact of the water flow on the support seat 108 b , and allows the water flow to evenly impact the blades of the guide member 112 .

[0086] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used.
