Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning nozzles, and in particular relates to a forward and reverse combined cleaning nozzle. Background Art

[0002] When it comes to cleaning the interior of a container, you will usually encounter parts inside the container, such as heat exchange coils and other built-in structures, which require a special cleaning nozzle.

[0003] In the prior art, three-dimensional nozzles are typically used to clean the interior of containers. These nozzles, arranged in an annular pattern, rotate around their axis to clean the container. However, each nozzle can only rotate clockwise or counterclockwise. When it comes to the corners of internal components, single-directional rotation may not fully clean them in one go (the water sprays out in an arc, leaving blind spots at corners). This requires replacing another nozzle (changing the rotation direction) and cleaning again, which is time-consuming and labor-intensive, as well as inefficient and impractical. Utility Model Content

[0004] The embodiment of the utility model provides a forward and reverse combined cleaning nozzle, which aims to solve the problem of poor practicality of the existing three-dimensional cleaning nozzle caused by unidirectional rotation.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is to provide a forward and reverse combined cleaning nozzle, comprising:

[0006] The intermediate connecting pipe has a tube cavity with an open end, and two groups of water outlet holes are provided on the side wall of the intermediate connecting pipe. The two groups of water outlet holes are spaced apart along the axis direction of the intermediate connecting pipe;

[0007] There are two rotating sleeves, each corresponding to the two groups of water outlet holes, and each rotating sleeve is coaxially connected to the intermediate connecting pipe through a bearing; each rotating sleeve is provided with a plurality of nozzles;

[0010] In a possible implementation, two bearings are provided between each rotating sleeve and the intermediate connecting pipe, and the two bearings are respectively located on both sides of the corresponding water outlet.

[0011] In a possible implementation, each group of the water outlet holes includes a plurality of water outlets annularly spaced along the axis of the intermediate connecting pipe.

[0012] In a possible implementation, each of the nozzles is arranged along the radial direction of the rotating sleeve.

[0013] In a possible implementation, the linkage structure includes:

[0014] There are two crown gears, the two crown gears are fixed on the two rotating sleeves respectively, and the tooth surfaces of the two crown gears are arranged facing each other;

[0015] There are at least two intermediate gears, and the two intermediate gears are arranged in a ring-shaped manner along the axial direction of the intermediate connecting tube. Each intermediate gear is rotatably set on the side wall of the intermediate connecting tube, and the rotation axis is set along the radial direction of the intermediate connecting tube. Each intermediate gear is respectively engaged with the two crown gears.

[0016] In a possible implementation, the driving structure includes:

[0023] a first worm wheel rotatably disposed in the cylindrical cavity and meshing with the first worm;

[0024] a second worm, coaxially connected to the first worm wheel;

[0025] a second worm gear rotatably disposed in the cylindrical cavity and meshing with the second worm;

[0026] a transmission shaft, rotatably disposed in the cylindrical cavity, and having one end coaxially connected to the second worm gear;

[0044] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Please also refer to Figure 1 and Figure 2 , the forward and reverse combination cleaning nozzle provided by the present invention is now described. The forward and reverse combination cleaning nozzle includes an intermediate connecting pipe 10, a rotating sleeve 20, a driving structure 30 and a linkage structure 40. The intermediate connecting pipe 10 has a lumen with an open end, and two groups of water outlet holes 11 are provided on the side wall of the intermediate connecting pipe 10. The two groups of water outlet holes 11 are arranged at intervals along the axial direction of the intermediate connecting pipe 10. There are two rotating sleeves 20, and the two rotating sleeves 20 correspond to the two groups of water outlet holes 11 respectively, and each rotating sleeve 20 is coaxially connected to the intermediate connecting pipe 10 through a bearing 21. A plurality of nozzles 22 are provided on each rotating sleeve 20. The driving structure 30 is arranged on the intermediate connecting pipe 10, and is dynamically connected to the rotating sleeve 20 away from the opening of the lumen to drive the rotating sleeve 20 away from the opening of the lumen to rotate in the forward direction. The linkage structure 40 is disposed between the two rotating sleeves 20 and is power-connected to the two rotating sleeves 20 , and can drive the rotating sleeve 20 close to the opening of the lumen to rotate in the opposite direction.

[0046] Compared to the prior art, the forward and reverse combined cleaning nozzle provided in this embodiment features an intermediate connecting pipe 10 that ensures connection to an external pressure water pipe, while a drive structure 30 disposed at the other end of the intermediate connecting pipe 10 ensures that one of the rotating sleeves 20 is driven to rotate forward, thereby driving the other rotating sleeve 20 to rotate in the reverse direction via a linkage structure 40. The water jets from the nozzles 22 on the two rotating sleeves 20 sweep the entire interior of the container 50 in opposite directions, avoiding blind spots and ensuring complete cleaning in one go, effectively improving cleaning efficiency and enhancing practicality.

[0047] In this embodiment, see Figure 6 , which is the water flow path sprayed by the nozzles 22 in the two rotating sleeves 20. After the water is swept, both sides of the corresponding fixed parts 60 inside the container 50 can be cleaned.

[0048] It should be noted that a connecting plate is provided at the open end of the lumen of the intermediate connecting tube 10, which may be a flange. This technology is prior art and will not be described in detail here.

[0049] In some embodiments, the rotating sleeve 20 may be used as follows: Figure 2 The structure shown. Figure 2 Two bearings 21 are provided between each rotating sleeve 20 and the intermediate connecting pipe 10 , and the two bearings 21 are respectively located on both sides of the corresponding water outlet 11 .

[0050] After the rotating sleeve 20 is mounted on the intermediate connecting pipe 10 and supported by the bearing 21, an annular water flow cavity is formed between the rotating sleeve 20 and the intermediate connecting pipe 10. The annular water flow cavity is connected to each water outlet 11. The provision of the bearing 21 ensures the sealing of the annular water flow cavity, thereby ensuring the water outlet effect, and has strong practicality.

[0051] In this embodiment, each bearing 21 may be a sealed bearing 21 .

[0052] In some embodiments, the water outlet 11 may be formed as follows: Figure 2 The structure shown. Figure 2 Each group of water outlet holes 11 includes multiple water outlets arranged at annular intervals along the axis of the intermediate connecting pipe 10. The arrangement of multiple water outlets can ensure the water output and thus ensure the cleaning effect.

[0053] In some embodiments, the nozzle 22 may be used as follows: Figures 1 to 2 The structure shown. Figures 1 to 2 Each nozzle 22 is arranged along the radial direction of the rotating sleeve 20, and the radial arrangement of the nozzle 22 can ensure the cleaning effect.

[0054] It should be noted that the end of the nozzle 22 can be configured as a universally adjustable structure, which is a prior art and will not be described in detail here.

[0055] Preferably, each rotating sleeve 20 is provided with two nozzles 22. The arrangement of the two nozzles 22 can ensure the spray pressure of the water flow and also ensure the force stability during the rotation process.

[0056] In some embodiments, the linkage structure 40 may be configured as follows: Figures 2 to 3 The structure shown. Figures 2 to 3The linkage structure 40 includes a crown gear 41 and an intermediate gear 42. Two crown gears 41 are provided, each fixed to the two rotating sleeves 20, with the tooth surfaces of the two crown gears 41 facing each other. At least two intermediate gears 42 are provided, annularly spaced along the axis of the intermediate connecting tube 10. Each intermediate gear 42 is rotatably mounted on the side wall of the intermediate connecting tube 10, with the rotation axis arranged along the radial direction of the intermediate connecting tube 10. Each intermediate gear 42 meshes with two crown gears 41.

[0057] The rotation of the intermediate gear 42 ensures that the two crown gears 41 rotate synchronously in opposite directions, thereby ensuring that the two rotating sleeves 20 rotate in opposite directions. The structure is simple and practical.

[0058] It should be noted that annular grooves may be provided at the opposite ends of the two rotating sleeves 20 to ensure the built-in positioning of the crown gear 41 and the intermediate gear 42. Figure 3 .

[0059] In some embodiments, the driving structure 30 may be configured as follows: Figures 2 to 5 The structure shown. Figures 2 to 4 The driving structure 30 includes a fixed cylinder 31, a rotating rod 32, an impeller 33 and a transmission component 34. The fixed cylinder 31 is fixed to the end of the intermediate connecting tube 10 away from the opening of the tube cavity, and has a tube cavity. The rotating rod 32 is located in the tube cavity and is coaxially arranged with the intermediate connecting tube 10. One end of the rotating rod 32 passes through one end of the intermediate connecting tube 10 and extends into the tube cavity. The impeller 33 is arranged in the tube cavity and is coaxially connected to the rotating rod 32. It can drive the rotating rod 32 to rotate as the water flows into the tube cavity. The transmission component 34 is arranged in the tube cavity and is dynamically connected to the rotating rod 32. The transmission component 34 can transmit the power of the rotating rod 32 to the rotating sleeve 20.

[0060] The intermediate connecting pipe 10 is connected to the pressure water pipe. The impeller 33 can be driven to rotate during the passage of water, thereby driving the rotating rod 32 to rotate, and then transmitting power to the transmission component 34, thereby driving the rotating sleeve 20 away from the opening of the tube cavity to rotate. It can achieve self-drive through water flow, save energy, and is highly practical.

[0061] In some embodiments, the transmission component 34 may be configured as follows: Figures 4 and 5 The structure shown. Figures 3 and 4The transmission component 34 includes a first worm 341, a first worm wheel 342, a second worm 343, a second worm wheel 344, a transmission shaft 345, a driving gear 346 and an internal gear 347. The first worm 341 is coaxially connected to one end of the rotating rod 32. The first worm wheel 342 is rotatably set in the cylindrical cavity and meshes with the first worm 341. The second worm 343 is coaxially connected to the first worm wheel 342. The second worm wheel 344 is rotatably set in the cylindrical cavity and meshes with the second worm 343. The transmission shaft 345 is rotatably set in the cylindrical cavity, and one end is coaxially connected to the second worm wheel 344. The driving gear 346 is coaxially set at the other end of the transmission shaft 345. The internal gear 347 is coaxially fixed on the rotating sleeve 20, and the internal gear 347 has an internal tooth surface that meshes with the driving gear 346.

[0062] The first worm 341, the first worm gear 342, the second worm 343, and the second worm gear 344 ensure power transmission, fully utilize the space of the barrel cavity, and avoid interference during transmission. The power is then transmitted to the driving gear 346 via the transmission shaft 345, and the driving gear 346 drives the internal gear 347 to rotate, thereby driving the rotating sleeve 20.

[0063] Specifically, a support structure 348 for rotatably connecting the first worm gear 342 , the second worm gear 344 and the transmission shaft 345 is fixed in the cylinder cavity.

[0064] In this embodiment, an accommodating space for fixing the internal gear 347 may be provided at the end of the rotating sleeve 20 .

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
