[0024] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention is described below using specific embodiments illustrated in the accompanying drawings. However, it should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0025] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0027] Example 1: Figures 1 to 6As shown, a three-dimensional cleaning nozzle is mainly composed of a connecting sleeve 1, a drive assembly outer cylinder 2, a rotating water outlet 3, a nozzle 5, a nozzle 6, and a drive assembly 7. The connecting sleeve 1 has a water inlet 1-1 at one end that communicates with an external water pipe. The connecting sleeve 1, the drive assembly outer cylinder 2, the rotating water outlet 3, and the nozzle 5 form a water injection channel connected to the nozzle 6. The water injection channel is connected to the water inlet 1-1. The water inlet 1-1 is a threaded connection. The external water pipe can be connected to the water inlet 1-1 by simply screwing it into the water inlet 1-1, without the need for special tools or equipment, making assembly very convenient. Similar to the ease of assembly, the threaded connection is also very convenient to disassemble. Simply unscrewing can separate the water pipe and the nozzle, facilitating maintenance. The other end of the connecting sleeve 1 is sealed and connected to the outer cylinder 2 of the driving component, the outer cylinder 2 of the driving component and the rotating water outlet 3, and the nozzle 5 and the rotating water outlet 3 are connected internally. The nozzle 6 is installed at the nozzle 5, and the driving component 7 is installed in the outer cylinder 2 of the driving component, the rotating water outlet 3 and the nozzle 5. The rotating water outlet 3, the nozzle 5 and the nozzle 6 can be rotated around the central axis 11 of the outer cylinder 2 of the driving component through the driving component 7, thereby realizing rotatable cleaning of the nozzle and ensuring the cleaning effect. The cleaning nozzle works through a plunger pump. Specifically, the inlet of the plunger pump is connected to the water outlet of the water tank truck, and then the outlet of the plunger pump is connected to the water pipe, and the water outlet end of the water pipe is connected to the water inlet 1-1 on the connecting sleeve 1. The water inlet 1-1 is connected to the above-mentioned water injection channel and the nozzle 6. The plunger pump increases the pressure to force the water in the water tank truck to be transported to the nozzle through the water pipe, and then a high-pressure water column is ejected outward through the nozzle 6 on the nozzle to flush the pipe or tank.

[0028] In order to expand the cleaning range and improve the cleaning rate, in this embodiment, the above-mentioned nozzle 5 is set on the side of the above-mentioned rotating water outlet 3. By installing the nozzle 5 laterally, the water can be sprayed to the side, thereby covering a wider cleaning area. Specifically, in order to enable the above-mentioned rotating water outlet 3 to drive the above-mentioned nozzle 5 and nozzle 6 to rotate, the above-mentioned drive assembly 7 in this embodiment includes a reducer 7-1, a drive shaft 7-2, a fixed gear 7-3, a rotating gear 7-4, an impeller shaft 7-5 and an impeller 7-6. The above-mentioned drive shaft 7-2 is the output shaft of the above-mentioned reducer 7-1 and is installed at one end of the above-mentioned reducer 7-1. The above-mentioned impeller shaft 7-5 is the input shaft of the above-mentioned reducer 7-1 and is installed at the other end of the above-mentioned reducer 7-1. The above-mentioned impeller 7-6 is installed on the above-mentioned impeller shaft 7-5. The above-mentioned fixed gear 7-3 is installed on the above-mentioned drive shaft 7-2 and is located in the above-mentioned rotating water outlet 3. The above-mentioned rotating gear 7-4 meshes with the above-mentioned fixed gear 7-3 and is located in the above-mentioned nozzle 5. Among them, the fixed gear 7-3 and the rotating gear 7-4 are bevel gears. Due to their unique tooth design, the bevel gears can provide a stable transmission ratio. The stable transmission ratio can ensure the stability of the nozzle during use. The structure of the bevel gear is relatively compact compared to traditional gears, which makes the overall structure of the nozzle compact and miniaturized, making it easy for users to use. An anti-slip component 7-7 is installed on the impeller shaft 7-5 outside the impeller 7-6. The impeller 7-6 is located in the connecting sleeve 1. The energy of the pressurized water flow can be converted into kinetic energy through the impeller 7-6, thereby providing energy for the reducer 7-1 to ensure the function of the reducer 7-1, and then the fixed gear 7-3 is driven by the reducer 7-1, thereby driving the rotating gear 7-4 to rotate on the fixed gear 7-3, and then driving the nozzle 5 and the nozzle 6 to realize the rotation action of the nozzle 6 to meet the use requirements.

[0029] In the sprinkler in the prior art, the planetary gear set in the reducer is usually composed of a sun gear, three planetary gears and an internal gear. When in use, when the water flow drives the internal gear set of the sprinkler to gradually reduce from high-speed rotation to the required low speed, the rotating shaft in the cavity is subjected to a large torque in this process, causing the gear set to often get stuck, jammed, etc., and the rotating shaft is prone to breakage during use, affecting the use effect and service life of the sprinkler, and thus affecting the user experience. To solve the above technical problems, the reducer 7 in this embodiment is a planetary gear reducer, including multiple sets of planetary gear sets 7-8, each set of the planetary gear sets 7-8 includes planetary gears 7-8-1, sun gears 7-8-2 and planetary gear discs 7-8-3. The number of the planetary gears 7-8-1 is greater than three and all are mounted on the planetary gear discs 7-8-3. The sun gear 7-8-2 is mounted at the center of the multiple planetary gears 7-8-1. Specifically, the number of planetary gears 7-8-1 can be four. By increasing the number of planetary gears 7-8-1, the stress state of the planetary gear sets 7-8 is improved, thereby increasing the service life of the reducer 7 and enhancing the practicality of the nozzle. The planetary gear sets 7-8 can be designed as multiple sets as needed, and the multiple sets of the planetary gear sets 7-8 are mounted on the drive shaft 7-2 at intervals. To ensure the service life of the drive shaft 7-2 and reduce the probability of breakage, the drive shaft 7-2 in this embodiment is made of stainless steel. After fabrication, it undergoes a heat treatment to achieve a surface hardness of HRC44-47. This means that after the heat treatment, the hardness of the drive shaft 7-2 reaches a range of 44 to 47 on the Rockwell C scale. This ensures that the transmission shaft 9 has sufficient strength and good wear resistance, while preventing breakage or cracking during use due to excessive brittleness. To reduce leakage and thereby improve the effective utilization of high-pressure water, a Che seal is used at the connection between the rotating water outlet 3 and the outer cylinder of the drive assembly.

[0030] To improve water flow efficiency and ensure effective use, a water flow guide block 8 is installed within the connecting sleeve 1. The water flow guide block 8 has multiple water flow holes 8-1, and the multiple water flow holes 8-1 are evenly distributed within the water flow guide block 8. The outer diameter of the water flow guide block 8 is compatible with the inner diameter of the connecting sleeve 1. To prevent impurities in the water from affecting components such as the interior of the nozzle, a filter screen 9 is installed within the connecting sleeve 1 at the water inlet 1-1. The filter screen 9 can intercept large particles of impurities such as sand, soil, and organic matter in the water, preventing these impurities from entering the nozzle, thereby reducing the probability of clogging of the nozzle 5 and nozzle 6.

[0031] To facilitate maintenance and reduce the difficulty of maintenance, the rotating water outlet 3 in this embodiment is an open structure and a water outlet cover 4 is installed at the opening to seal it. Similarly, the exterior of the nozzle 5 can also be designed as an open structure, and a removable plug can be installed at the opening to facilitate user maintenance and repair of the nozzle 6 and the interior of the nozzle 5.

[0032] In order to increase the cleaning rate and shorten the cleaning time, in this embodiment, there are four nozzles 6 , which are equidistantly installed on the nozzle 5 .

[0033] In order to further improve the stability of the nozzle during use and facilitate the installation of the nozzle 5, a water outlet shaft 3-1 is formed on the side of the rotating water outlet 3, and the nozzle 5 is mounted on the water outlet shaft 3-1.

[0034] The above-mentioned connecting sleeve 1, the above-mentioned driving assembly outer cylinder 2, the above-mentioned rotating water outlet 3, the above-mentioned nozzle 5 and the above-mentioned nozzle 6 are all made of stainless steel. Stainless steel has good corrosion resistance to water and many chemical media, which is very important for cleaning nozzles that are often in contact with water and may contain chemical components. It can effectively extend the service life of the nozzle and reduce damage and maintenance costs caused by corrosion.

[0035] Example 2: This example differs from Example 1 in that it comprises a three-dimensional cleaning nozzle having two nozzles 6 symmetrically mounted on the nozzle 5, thereby ensuring the same performance. The number of nozzles 6 can be adjusted as needed; if the flow rate permits, a greater number of nozzles 6 results in higher cleaning efficiency.

[0036] A three-dimensional cleaning nozzle in the above embodiment has an ingenious structure. By setting a connecting sleeve 1, a driving component outer cylinder 2, a rotating water outlet 3, a nozzle 5, a nozzle 6 and a driving component 7, a water inlet 1-1 connected to an external water source is provided on the connecting sleeve 1, and the connecting sleeve 1 and the driving component outer cylinder 2, the driving component outer cylinder 2 and the rotating water outlet 3, the rotating water outlet 3 and the nozzle 5 are all sealed and connected internally to form a water supply channel for supplying water to the nozzle, and then the direction of the nozzle 5 and the nozzle 6 is changed by the internal driving component 7, even if the nozzle 6 can be moved along The central axis 11 of the outer cylinder 2 of the driving component rotates, the fixed gear 7-3 is fixed at the outer cylinder 2 of the driving component, and the rotating gear 7-4 is fixed at the nozzle 5. The nozzle 5 rotates around the central axis 11 and at the same time rotates around the central axis 2 12 through the engagement of the fixed gear 7-3 and the rotating gear 7-4, and the water flow is sprayed 360 degrees without dead angles, thereby realizing cleaning of the inner wall or other parts of the tank body. There is no need for the operator to enter the tank, which reduces the labor intensity of the operator and enhances the user experience, which is conducive to the promotion and application of the above-mentioned three-dimensional cleaning nozzle in the market.

[0037] The three-dimensional cleaning nozzle in the above embodiment only needs to be placed inside the container during cleaning. Water flow from the external water pipe drives the internal impeller 7-6 to rotate. The reducer 7-1 is a planetary reducer that controls the speed, causing the rotating gear 7-4 to mesh with the fixed gear 7-3, which in turn rotates the nozzle 360 ​​degrees. This eliminates the need for manual entry into the container, thus preventing accidents. The nozzle itself has no explosion source, making it safer for cleaning flammable and explosive tanks.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
