Description

Technical Field

[0001] The utility model relates to the technical field of cleaning machine nozzles, in particular to a swing structure of a nozzle of a cleaning machine. Background Technique

[0002] Among all cleaning methods, the spray cleaning machine is a method with the highest efficiency and unified effect. The reason why the spray cleaning machine can achieve such an effect is closely related to its unique working principle and cleaning method. In production and life, there are many things that need to be cleaned, and there are also many types and links that need to be cleaned, such as: removing oil stains, dust, surface rust prevention, etc. from objects. The common manual cleaning method is slow in speed and high in cost, while the spray cleaning machine can clean workpieces in batches, with a unified effect, strong controllability, and low cost. Therefore, the spray cleaning machine is increasingly widely used in various industries. When the existing cleaning machine works, the cleaning solution located inside the water tank is pumped into the water pipe by a water pump, enters each spray rack through the water pipe, and then sprays out from the nozzles to achieve the cleaning purpose. The nozzles of the traditional cleaning machine are fixed on the spray rack. When cleaning workpieces, there will be spray dead corners and the cleaning effect is poor. For this reason, we propose a swing structure of the nozzle of the cleaning machine. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a swing structure of a nozzle of a cleaning machine. It is provided with a swingable nozzle structure. When performing cleaning work, the motor drives the connecting pipe to rotate back and forth through a connecting rod, thereby driving the nozzle to swing back and forth. The swing amplitude of the nozzle can also be adjusted by changing the length of the connecting rod, so as to quickly and accurately perform cleaning work on the material, and effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a swing structure of a nozzle of a cleaning machine, including a housing and a swing mechanism;

[0005] Housing: A connecting pipe is rotatably connected to the middle of the right end of the front side inside it, and a nozzle is provided at the upper middle part of the outer surface of the connecting pipe;

[0006] Swing mechanism: It includes a rotating shaft, a connecting block, a connecting cylinder and a connecting rod. The rotating shaft is rotatably connected to the middle of the right end of the rear side inside the housing. Connecting blocks are provided at the right ends of both the connecting pipe and the rotating shaft. The connecting cylinders are rotatably connected to the right sides of the connecting blocks through pins. A connecting rod is provided between the two connecting cylinders, providing a basis for the swing of the nozzle. It is provided with a swingable nozzle structure. When performing cleaning work, the motor drives the connecting pipe to rotate back and forth through the connecting rod, thereby driving the nozzle to swing back and forth. The swing amplitude of the nozzle can also be adjusted by changing the length of the connecting rod, so as to quickly and accurately perform cleaning work on the material.

[0007] Further, the outer surface of the connecting rod is provided with uniformly distributed external threads, and the outer surface of the connecting rod is threadedly connected to the inner wall of the connecting cylinder, so that the swinging amplitude of the nozzle can be adjusted according to the actual situation.

[0008] Further, the vertical distance between the pin shaft at the front side and the axis of the connecting pipe is greater than the vertical distance between the pin shaft at the rear side and the axis of the rotating shaft, so that the connecting block at the rear side can rotate and drive the connecting block at the front side to swing back and forth at the same time.

[0009] Further, the swinging mechanism further includes a motor, the motor is arranged at the rear side inside the housing, the input end of the motor is electrically connected to the output end of an external control switch, and the right end of the output shaft of the motor is fixedly connected to the left end of the rotating shaft, providing stable drive for the swinging of the nozzle.

[0010] Further, the swinging mechanism further includes a fixing frame and a rotary joint. The fixing frame is arranged at the middle of the front end of the left side wall of the housing.

[0012] Further, it further includes an end cover. The end cover is arranged at the right end of the housing, providing a protection effect for the swinging mechanism.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The nozzle swinging structure of this cleaning machine has the following advantages:

[0014] 1. The motor drives the connecting block at the rear side to rotate. The connecting cylinder at the rear side also rotates in a circular motion with the axis of the rotating shaft as the center. The rotation radius of the connecting cylinder at the front side is greater than that of the connecting cylinder at the rear side, forming the crank and connecting rod principle. As the connecting block at the rear side rotates, the connecting block at the front side also swings back and forth with the axis of the connecting pipe as the center, driving the connecting pipe to rotate back and forth, thereby driving the nozzle to swing back and forth.

[0015] 2. When the two connecting cylinders rotate forward, the two connecting cylinders move inward, and the overall length of the combination of the connecting cylinder and the connecting rod becomes shorter. When the combination of the connecting cylinder and the connecting rod transmits power, the swinging amplitude of the nozzle becomes larger. When the connecting cylinder rotates in reverse, the two connecting cylinders move outward, and the overall length of the combination of the connecting cylinder and the connecting rod becomes longer. At this time, when the combination of the connecting cylinder and the connecting rod transmits power, the swinging amplitude of the nozzle becomes smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3 , this embodiment provides a technical solution: the nozzle swing structure of the cleaning machine, including a housing 1 and a swing mechanism 3;

[0022] Housing 1: A connecting pipe 2 is rotatably connected to the middle of the right end of the front side inside it. A nozzle 4 is provided at the upper middle part of the outer surface of the connecting pipe 2. An end cover 6 is further included. The end cover 6 is arranged at the right end of the housing 1 to provide a protective effect for the swing mechanism 3;

[0023] Swing mechanism 3: It includes a rotating shaft 31, a connecting block 32, a connecting cylinder 33 and a connecting rod 34. The rotating shaft 31 is rotatably connected to the middle of the right rear side inside the housing 1. Connecting blocks 32 are provided at the right ends of both the connecting pipe 2 and the rotating shaft 31. The connecting cylinders 33 are rotatably connected to the right sides of the connecting blocks 32 through pin shafts. A connecting rod 34 is provided between the two connecting cylinders 33, providing a basis for the swing of the nozzle 4. Uniformly distributed external threads are provided on the outer surface of the connecting rod 34, and the outer surface of the connecting rod 34 is threadedly connected to the inner wall of the connecting cylinder 33, so that the swing amplitude of the nozzle 4 can be adjusted according to the actual situation. The vertical distance between the pin shaft at the front side and the axis of the connecting pipe 2 is greater than the vertical distance between the pin shaft at the rear side and the axis of the rotating shaft 31, which can realize the rotation of the connecting block 32 at the rear side and drive the connecting block 32 at the front side to swing back and forth. The swing mechanism 3 further includes a motor 35. The motor 35 is arranged at the rear side inside the housing 1. The input end of the motor 35 is electrically connected to the output end of an external control switch. The right end of the output shaft of the motor 35 is fixedly connected to the left end of the rotating shaft 31, providing stable drive for the swing of the nozzle 4. The swing mechanism 3 further includes a fixing frame 36 and a rotary joint 37. The fixing frame 36 is arranged at the middle of the front end of the left side wall of the housing 1. The fixed end of the rotary joint 37 is arranged inside the fixing frame 36. The rotary end at the left end of the rotary joint 37 is fixedly connected to the right end of the connecting pipe 2. The lower end of the rotary joint 37 is communicated with an external water pipe, ensuring the stability of the connection between the connecting pipe 2 and the external water pipe. It further includes a motor protective cover 5. The motor protective cover 5 is arranged in the middle inside the housing 1. The front side of the motor protective cover 5 is an inclined wall body, protecting the motor 35 and providing an avoidance effect for the swing of the nozzle 4. There is a swingable nozzle structure. When performing the cleaning work, the motor drives the connecting pipe to rotate back and forth through the connecting rod, thereby driving the nozzle to swing back and forth. The swing amplitude of the nozzle can also be adjusted by changing the length of the connecting rod, so as to quickly and accurately clean the material.

[0024] The working principle of the nozzle swing structure of the cleaning machine provided by the present utility model is as follows: When the nozzle 4 performs the cleaning work, the cleaning solution located inside the water tank is pumped into the water pipe by an external water pump, passes through the rotary joint 37 and the connecting pipe 2, and then sprays out from the nozzle 4. At this time, the external control switch controls the operation of the motor 35. The output shaft of the motor 35 drives the rotation of the rotating shaft 31, and the rear connecting block 32 also rotates accordingly. The rear connecting cylinder 33 also makes a circular motion around the axis of the rotating shaft 31. Because the outer surfaces of the connecting rods 34 are threadedly connected to the inner walls of the connecting cylinders 33, as the rear connecting cylinder 33 moves, the front connecting cylinder 33 also starts to move synchronously. Since the vertical distance between the front pin shaft and the axis of the connecting pipe 2 is greater than the vertical distance between the rear pin shaft and the axis of the rotating shaft 31, the rotation radius of the front connecting cylinder 33 is greater than the rotation radius of the rear connecting cylinder 33. Therefore, as the rear connecting block 32 rotates, the front connecting block 32 also swings back and forth around the axis of the connecting pipe 2, driving the connecting pipe 2 to rotate back and forth, thereby driving the nozzle 4 to swing back and forth. The nozzle 4 changes the spraying angle of the cleaning solution through the back-and-forth swing, which can make the cleaning effect better. The rotary joint 37 can rotate 360° to convey the medium, and the connecting pipe 2 can stably and efficiently convey the cleaning solution from the external water pipe to the inside of the nozzle 4, thus ensuring the stability of the cleaning solution conveyance. When it is necessary to change the swing amplitude of the nozzle 4, only the connecting cylinder 33 and the connecting rod 34 need to be removed. When the connecting cylinder 33 is rotated forward, the two connecting cylinders 33 move inward, and the overall formed by the connecting cylinder 33 and the connecting rod 34 becomes shorter. At this time, when the overall formed by the connecting cylinder 33 and the connecting rod 34 is in transmission, the swing amplitude of the nozzle 4 becomes larger. When the connecting cylinder 33 is rotated reversely, the two connecting cylinders 33 move outward, and the overall formed by the connecting cylinder 33 and the connecting rod 34 becomes longer. At this time, when the overall formed by the connecting cylinder 33 and the connecting rod 34 is in transmission, the swing amplitude of the nozzle 4 becomes smaller.

[0025] It should be noted that the motor 35 disclosed in the above embodiments is a 36GP-36ZY motor, and the external control switch controls the operation of the motor 35 using the methods commonly used in the prior art.

[0026] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
