Any embodiment described in this application as "exemplary" is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any person skilled in the art to implement and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the invention can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0038] The embodiments of the present application provide a cleaning nozzle assembly and a cleaning system, which are described in detail below.
[0039] First, see Figure 1 as well as Figure 2 , Figure 1 A schematic diagram of the structure of the cleaning nozzle assembly in an embodiment of the present application is shown. Figure 2 A cross-sectional schematic diagram of a cleaning nozzle assembly in an embodiment of the present application is shown, wherein the cleaning nozzle assembly includes:
[0040] The nozzle body 10 is provided with a liquid passage 11 and a gas passage 12;
[0041] The nozzle body 10 has a first fluid output mode and a second fluid output mode, and the nozzle body 10 switches back and forth between the second fluid output mode and the first fluid output mode;
[0042] When the nozzle body 10 is in the first fluid output mode, liquid is sprayed out through the liquid channel 11 to clean the object; when the nozzle body 10 is in the second fluid output mode, gas is sprayed out through the gas channel 12 to dry the object.
[0043] Specifically, the nozzle body 10 is used to form a liquid channel 11 and a gas channel 12 to spray gas (such as air, nitrogen, etc.) and liquid (cleaning liquid, water, etc.), see Figure 3 as well as Figure 4 , Figure 3 A schematic diagram of the structure of the nozzle body 10 in the embodiment of the present application is shown. Figure 4 A cross-sectional schematic diagram of the nozzle body 10 in the embodiment of the present application is shown, wherein the nozzle body 10 is provided with a liquid inlet 13 and a liquid outlet 14 connected to the liquid channel 11, and a gas inlet 15 and a gas outlet 16 connected to the gas channel 12. Generally, the nozzle body 10 is cylindrical, and the gas inlet 15 and the gas outlet 16 are located on the cylindrical surface of the nozzle body 10, so that the outlet direction can be adjusted by rotating the nozzle body 10, thereby changing the angle at which the nozzle body 10 sprays liquid and gas.
[0044] In the above embodiment, liquid flows in through the liquid inlet 13 and is finally ejected from the liquid outlet 14, and gas flows in through the gas inlet 15 and is finally ejected from the gas outlet 16. In the actual cleaning operation, the cleaning nozzle assembly first ejects high-pressure liquid (e.g., 10Mpa high-pressure water) for cleaning, and then ejects high-pressure gas (e.g., 0.5Mpa high-pressure air) for drying after cleaning is completed, thereby providing a cleaning nozzle assembly that provides cleaning and drying functions.
[0045] It can be understood that the liquid channel 11 and the gas channel 12 can also share the same inlet and the same outlet. After the nozzle body 10 receives the liquid through the inlet, the liquid flows into the liquid channel 11 and is finally ejected through the outlet; after the nozzle body 10 receives the gas through the inlet, the gas flows into the gas channel 12 and is finally ejected through the outlet.
[0046] The present application provides a liquid channel 11 and a gas channel 12 on the nozzle body 10, and the nozzle body 10 can switch back and forth between the second fluid output mode and the first fluid output mode. When the nozzle body 10 is in the first fluid output mode, liquid is sprayed out through the liquid channel 11 to clean the object; when the nozzle body 10 is in the second fluid output mode, gas is sprayed out through the gas channel 12 to dry the object, so that the nozzle body 10 has both cleaning and drying functions, which can shorten the drying time of the object after liquid cleaning, thereby improving the cleaning efficiency of the parts.
[0047] In some embodiments of the present application, see Figure 3 as well as Figure 4 The liquid inlet 13 is arranged at one end of the nozzle body 10, and the gas outlet 16 and the liquid outlet 14 are arranged at the other end of the nozzle body 10, and the gas outlet 16 and the liquid outlet 14 are in opposite directions. Generally, the gas outlet 16 and the liquid outlet 14 are both arranged on the outer wall surface, and the directions of the gas outlet 16 and the liquid outlet 14 can be adjusted simultaneously during the rotation of the nozzle body 10, so it is beneficial to change the gas injection angle and the liquid injection angle.
[0048] Further, in order to facilitate changing the angle at which the nozzle body 10 sprays liquid or gas, in some embodiments of the present application, refer to Figure 1 , Figure 2 , Figure 5 as well as Figure 6 , Figure 4 A schematic diagram of the structure of the rotating docking member 20 in the embodiment of the present application is shown. Figure 6 A cross-sectional schematic diagram of the rotating docking piece 20 in the embodiment of the present application is shown, wherein the cleaning nozzle assembly also includes a rotating docking piece 20, the rotating docking piece 20 has a through groove 21, and the rotating docking piece 20 is sleeved on the outer wall surface of the nozzle body 10 through the through groove 21. The inner wall surface of the through groove 21 is provided with a first annular groove 22. The first annular groove 22 and the outer wall surface of the nozzle body 10 are enclosed to form an annular flow channel 23. The annular flow channel 23 is connected to the gas channel 12 so that during the rotation of the nozzle body 10, the gas flows in the annular flow channel 23 and the gas channel 12.
[0049] Since the rotating docking piece 20 is provided with a through groove 21, and is sleeved on the outer wall surface of the nozzle body 10 through the through groove 21, the rotating docking piece 20 and the nozzle body 10 can rotate relative to each other. In combination with some embodiments of the present application, for example, for embodiments in which the gas outlet 16 and the liquid outlet 14 are oriented in opposite directions, the injection angle of the gas or liquid can be changed when the nozzle body 10 rotates, so that the workpiece can be cleaned and dried more flexibly. Generally, in order to facilitate the introduction or output of fluid, the rotating docking piece 20 is provided with a delivery channel 24 connected from its outer wall surface to the first annular groove 22, so that the fluid can flow into the annular flow channel 23 through the delivery channel 24, or the fluid can be discharged from the delivery channel 24. As an example, the axis of the delivery channel 24 is perpendicular to the axis of the nozzle body 10.
[0050] In the above embodiment, the angle of the fluid ejected from the cleaning nozzle assembly can be adjusted by rotating the nozzle body 10. Compared with the current solution of controlling the movement of the nozzle by a manipulator to adjust the angle of the fluid ejected from the nozzle, the nozzle spray angle adjustment structure is simplified; at the same time, since the first annular groove 22 is provided on the inner wall surface of the through groove 21 of the rotating docking member 20, the first annular groove 22 and the outer wall surface of the nozzle body 10 are enclosed to form an annular flow channel 23, and the annular flow channel 23 is connected to the gas channel 12, so that during the rotation of the nozzle body 10, the gas flows in the annular flow channel 23 and the gas channel 12, thereby avoiding leakage caused by the nozzle body 10 or.
[0051] In some embodiments of the present application, for example, the nozzle body 10 is provided with a liquid inlet 13 and a liquid outlet 14 connected to the liquid channel 11, and a gas inlet 15 and a gas outlet 16 connected to the gas channel 12, see Figure 1 as well as Figure 2 The rotating docking member 20 is installed at the gas inlet 15, and the gas inlet 15 is opposite to the first annular groove 22, so that the annular flow channel 23 and the gas channel 12 are connected through the gas inlet 15. In this embodiment, the gas flows through the delivery channel 24, the annular flow channel 23, and the gas channel 12 in sequence. Since the annular flow channel 23 is sealed with the outer wall of the nozzle body 10 through the rotating docking member 20, no leakage will occur at the annular flow channel 23.
[0052] It is understandable that another rotating docking member 20 may be provided and installed at the liquid inlet 13 to avoid liquid leakage caused by the nozzle body 10 .
[0053] Further, in order to ensure the sealing of the joint between the rotating joint member 20 and the nozzle body 10, in some embodiments of the present application, continue to refer to Figure 2 as well as Figure 6 , wherein a second annular groove 25 and a third annular groove 26 are further provided on the inner wall surface of the through groove 21, and the second annular groove 25 and the third annular groove 26 are respectively located on both sides of the first annular groove 22, and the second annular groove 25 and the outer wall surface of the nozzle body 10 are enclosed to form a first annular space 210, and the third annular groove 26 and the outer wall surface of the nozzle body 10 are enclosed to form a second annular space 220.
[0054] Specifically, as an example, a first sealing ring 27 is installed in the first annular space 210, and a second sealing ring 28 is installed in the second annular space 220. For the annular flow channel 23, since there are sealing ring structures on both sides, when the fluid flows in the annular flow channel 23, the sealing ring structure prevents the fluid from continuing to flow to both sides, thereby improving the sealing performance of the docking point between the rotating docking piece 20 and the nozzle body 10.
[0055] As another example, the outer surface of the nozzle body 10 is provided with a first annular boss and a second annular boss opposite to the second annular groove 25 and the third annular groove 26, and multiple sealing surfaces are formed by the cooperation of the grooves and the bosses, thereby improving the sealing performance of the docking point between the rotating docking piece 20 and the nozzle body 10.
[0056] In some embodiments of the present application, for example, in an embodiment in which a first sealing ring 27 is installed in the first annular space 210 and a second sealing ring 28 is installed in the second annular space 220, the first sealing ring 27 can also contact the first annular boss and the second annular groove 25 on both sides, and the second sealing ring 28 can contact the second annular boss and the third annular groove 26 on both sides. After the cleaning nozzle assembly is assembled, the extrusion of the boss and the groove causes the sealing ring to elastically deform, thereby utilizing the elastic force of the sealing ring to restore the deformation to improve the sealing performance of the cleaning nozzle assembly.
[0057] It is worth noting that the above description of the cleaning nozzle assembly is only for clarifying the verification process of the present application. Under the guidance of the present application, those skilled in the art can make equivalent modification designs to the above cleaning nozzle assembly, for example, setting more channels to spray other fluids, such as cleaning agents, etc.
[0058] Furthermore, in order to better implement the cleaning nozzle assembly in the embodiment of the present application, based on the cleaning nozzle assembly, a cleaning system is also provided in the embodiment of the present application, and the cleaning system includes:
[0059] A cleaning nozzle assembly as described in any of the above embodiments;
[0060] The liquid supply device and the air supply device are connected to the nozzle body 10 of the cleaning nozzle assembly.
[0061] Specifically, the liquid supply device is a device / device for conveying liquid, such as a centrifugal pump, a vane pump, etc.; the gas supply device is a device / device for conveying gas, such as a blower, a compressor, etc. When the nozzle body 10 is in the first fluid output mode, the liquid supply device passes liquid into the liquid channel 11, and when the nozzle body 10 is in the second fluid output mode, the gas supply device passes gas into the gas channel 12, so that the nozzle body 10 can spray liquid or gas in different output modes to clean or dry the workpiece.
[0062] In some embodiments of the present application, the cleaning system may further include a rotating mechanism, and the rotating mechanism and the nozzle body 10 of the cleaning nozzle assembly are connected to drive the nozzle body 10 to rotate and change the spray angle of the nozzle body 10. Exemplarily, the rotating mechanism may use a motor to realize the rotation function through a transmission structure (gear, belt) and the like.
[0063] Furthermore, in some embodiments of the present application, the cleaning system may further include a moving mechanism, such as a three-dimensional moving mechanism, to drive the cleaning nozzle assembly to move, thereby further improving the flexibility of the cleaning nozzle assembly. The cleaning system in the embodiment of the present application has all the beneficial effects of the cleaning nozzle assembly of the above embodiment because it is provided with the cleaning nozzle assembly of the above embodiment, which will not be described in detail here.
