Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a dual-drive spray device for cleaning equipment. Background Technology

[0002] In cleaning equipment, the spraying device is the main cleaning component. The rotating shaft of the rotating spray arm is driven to rotate by a motion system or power device, and sprays out cleaning water to achieve cleaning.

[0003] To ensure effective cleaning, multiple sets of nozzles or rotating nozzles are typically used to spray water over a sufficient area. However, deploying multiple nozzles increases costs, and some areas may remain uncovered. While multiple nozzles can help maintain the flushing power of the spray, rotating nozzles, which usually operate on a single shaft, still have blind spots and limitations. Furthermore, leaks in the rotating pipe connections can lead to poor cleaning results. Therefore, we propose a dual-drive spray device for cleaning equipment. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] A dual-drive spray device for cleaning equipment, such as Figure 1 - Figure 4As shown, the device includes a housing 1, with a flange 2 rotatably connected to the top of the housing 1. The flange 2 is fixedly connected to the cleaning chamber of the cleaning equipment. A gear 4 is rotatably connected to one side inside the housing 1. A rotary joint is located on the housing 1 below the gear 4. A spray arm 3 is connected to the bottom of the inner wall of the housing 1 and extends to the rotary joint, communicating with it. A nozzle 5 is fixedly connected to the gear 4 and communicates with the spray arm 3, extending to the outside of the housing 1. A guide pipe 6 is connected to the end of the spray arm 3 away from the rotary joint. The guide pipe 6 passes through the central hole of the flange 2 and extends to the outside of the housing 1 for connecting to a water source. A sealing ring is provided between the guide pipe 6 and the spray arm 3, and a locking clamp is fitted on the outside of the connection.

[0029] In this embodiment, the guide pipe 6 is used as part of the water flow channel. The guide pipe 6 is directly inserted into the spray arm 3 through the flange 2, which eliminates the need for a complex sealing structure, reduces equipment costs, and facilitates maintenance.

[0030] like Figure 1-5 As shown, preferably, a central motor 7 is fixedly connected to the middle of the inner wall of the housing 1. The output shaft of the central motor 7 is a hollow gear, which is fixedly connected to the flange 2 and is used to drive the housing 1 to rotate around the output shaft of the central motor 7. A gear is sleeved on the outer wall of the gear 4. A spray motor 8 is fixedly connected to the inner wall of the housing 1. The spray motor 8 drives the gear on the gear 4 to rotate. The spray motor 8 and the central motor 7 are both meshed and transmitted through a reduction gear set to ensure that the central motor 7 and the spray motor 8 can be driven at a uniform speed and smoothly.

[0031] In this embodiment, after the central motor 7 is started, the gear driven by the central motor 7 is fixedly connected to the flange 2, causing the lower housing 1 to rotate around the flange 2. At the same time, the nozzles 5 installed on the housing 1 rotate together. Meanwhile, the spray motor 8 drives the nozzles 5 to rotate. Driven by two different rotation axes, the spray of the nozzles 5 can achieve a combination of rotation and revolution. In one cycle of rotation, a large coverage area can be achieved, and the cleaning efficiency is significantly improved through large-area cleaning coverage. This solves the technical problem of small water flow coverage and low cleaning efficiency of the existing spray device. Furthermore, the use of dual motor drive also improves the controllability of the spray trajectory.

[0032] Specifically, water flows through the guide pipe 6 into the spray arm 3, and finally sprays through the nozzle 5. At the same time, since the gear driven by the central motor 7 is fixedly connected to the flange 2, the lower housing 1 rotates around the flange 2, which in turn drives the nozzle 5 mounted on the housing 1 to rotate. Meanwhile, the spray motor 8 drives the nozzle 5 to rotate. Driven by two different rotation axes, the spraying of the nozzle 5 can achieve a combination of rotation and revolution, which can achieve a large coverage area.

[0033] like Figure 1-5 As shown, preferably, the housing 1 is composed of two parts, upper and lower, which can be disassembled for maintenance. A retaining ring is provided at the connection between the flange 2 and the housing 1 to limit the axial displacement of the flange 2 and the housing 1 and increase the stability of the connection.

[0034] like Figure 1-5 As shown, preferably, the nozzle 5 includes a rod segment, a mounting head, and a nozzle. The rod segment is fixedly connected to the gear 4, and the mounting head is fixedly connected to the bottom of the rod segment. The mounting head is used to connect the nozzle. The inner wall of the rotary joint is provided with two sealing rings. The two sealing rings are sleeved on the outer wall of the rod segment at the positions on both sides of the channel. Pressure plates are respectively provided on the outer wall of the rod segment on the side away from the channel of the two sealing rings to limit the axial displacement of the sealing rings. The inner wall of the rotary joint has an annular groove for embedding the pressure plates to limit the axial displacement of the pressure plates.
