[0002] Patent publication number CN118161105A is a handheld cleaning device that uses water flow sprayed from a water nozzle to drive the impeller plate to rotate, and the impeller plate drives the brush on the bottom plate to rotate to clean the items, which saves energy and reduces the cost of use. When in use, the user holds the outer wall of the shell and uses the brush to clean the items, avoiding the discomfort of soaking both hands. The user experience is good and it is easy to use.

[0003] However, in the above patent, the impeller plate directly drives the brush on the bottom plate to rotate, the rotation speed of the brush is relatively fast, the brushing force acting on the article is relatively small, the cleaning effect of the brush is relatively poor, and the rotation speed of the bottom plate is too fast, the water flow at the leakage hole on the bottom plate splashes everywhere, polluting the surrounding cleaning environment. Utility Model Content

[0004] The purpose of this application is to provide a handheld cleaning device with high cleaning power. A gear ring and a driven wheel group are introduced between the impeller plate and the base plate. Through the transmission and deceleration effect of the gear ring and the driven wheel group, the problems of excessive brush speed, poor cleaning effect and water splashing pollution are solved, thereby improving the overall performance and user experience of the handheld cleaning device.

[0005] The technical solution adopted by the present application to solve the above technical problems is as follows: a handheld cleaning device with high cleaning power is proposed, comprising: a shell, a water inlet chamber is provided in the shell, a water inlet channel connected to the water inlet chamber is provided on the shell, a water spray port connected to the water inlet chamber is provided in the shell, a mounting shaft extending along the central axis of the shell is provided in the shell, the mounting shaft is located below the water inlet chamber and is rotatably connected to an impeller shaft on the outer periphery, a plurality of impeller plates are evenly spaced along the circumference of the outer periphery of the impeller shaft, a water spray end of the water spray port faces the impeller plate, a gear ring is provided on the outer periphery of the lower end of the impeller shaft, a driven wheel group is transmission-connected to the outer periphery of the driven wheel group, a bottom plate is provided at the lower end of the shell, the bottom plate is coaxially rotatably connected to the outer periphery of the mounting shaft, a plurality of brushes are spaced and connected to the lower end of the bottom plate, a water outlet is provided on the inner side of the brush on the bottom plate, and the water outlet is communicated with the water spray port.

[0006] Through the above technical features, a gear ring and a driven wheel set are introduced between the impeller plate and the bottom plate. Through the transmission deceleration effect of the gear ring and the driven wheel set, the rotation speed of the bottom plate is reduced relative to the rotation speed of the impeller shaft, and the rotation speed of the brush is also slowed down accordingly, thereby increasing the contact time and friction between the brush and the surface of the object, so that the brush can contact and clean the surface of the object at a lower speed but with greater torque, thereby improving the cleaning strength and cleaning effect. At the same time, because the rotation speed of the bottom plate is decelerated, the water flow at the water outlet on it will flow out more stably, reducing the phenomenon of splashing everywhere, and effectively protecting the surrounding clean environment.

[0007] Preferably, the outer periphery of the driven wheel group is meshingly connected to a gear ring, an end of the gear ring away from the driven wheel group is coaxially connected to a gear ring shaft, the gear ring shaft is rotatably connected to the outer periphery of the mounting shaft and a second bearing is provided between the gear ring shaft and the mounting shaft, and the base plate is coaxially connected to the gear ring shaft.

[0008] Through the above technical features, when the driven wheel group rotates, the driving gear ring rotates together, and the end of the gear ring away from the driven wheel group is coaxially connected to a gear ring shaft, and the gear ring shaft is rotatably connected to the outer periphery of the mounting shaft, and a second bearing is provided between the gear ring shaft and the mounting shaft so that the gear ring shaft can rotate smoothly. The bottom plate is coaxially connected to the gear ring shaft, so when the gear ring shaft rotates, the bottom plate will also rotate. Through the meshing transmission of the gear ring and the gear ring shaft, the rotation of the driven wheel group can be more effectively transmitted to the bottom plate, thereby improving the transmission efficiency.

[0009] Preferably, the driven wheel group includes a gear fixing frame, a first driven wheel, a second driven wheel, a driven wheel shaft, and a fourth bearing. The gear fixing frame is sleeved on the outer periphery of the lower end of the mounting shaft located at the impeller shaft, the first driven wheel is meshingly connected to the outer periphery of the gear ring, the driven wheel shaft is connected at the axis of the first driven wheel, the driven wheel shaft is rotatably connected to the gear fixing frame, the gear fixing frame is provided with a rotation groove corresponding to the driven wheel shaft, the fourth bearing is arranged between the inner circumferential wall of the rotation groove and the outer circumferential wall of the driven wheel shaft, the second driven wheel is connected to an end of the driven wheel shaft away from the first driven wheel, and the second driven wheel is meshingly connected to the gear ring.

[0010] Through the above technical features, the gear fixing frame provides a stable support platform for the driven wheel set, ensuring that the driven wheel set can rotate smoothly. As the gear ring rotates, the first driven wheel starts to rotate, and drives the second driven wheel to rotate through the driven wheel shaft, and the second driven wheel transmits power to the gear ring, thereby realizing the deceleration transmission of power in turn.

[0011] Preferably, a connecting sleeve extending upward is provided at the center of the base plate, the connecting sleeve is rotatably connected to the outer periphery of the mounting shaft via a third bearing, and the connecting sleeve is inserted into the gear ring shaft.

[0012] Through the above-mentioned technical features, the base plate is rotatably connected to the mounting shaft through the connecting sleeve, and the friction and wear are reduced through the third bearing. The plug-in connection between the connecting sleeve and the gear ring shaft makes the power transmission more direct and efficient, reduces the power loss during the transmission process, and improves the transmission efficiency.

[0013] Preferably, the bottom plate is coaxially disposed at the outer periphery of the connecting sleeve with a first retaining ring and a second retaining ring extending upward and downward respectively, and the water outlet is arranged between the first retaining ring and the second retaining ring and the connecting sleeve.

[0014] Through the above technical features, the water outlet is arranged between the first baffle ring, the second baffle ring and the connecting sleeve, and the sprayed water flow will be guided by the baffle ring and flow to the area that needs to be cleaned more concentratedly and orderly. The baffle ring also reduces the splashing and diffusion of the water flow during the spraying process, thereby maintaining a tidy cleaning environment.

[0015] Preferably, a water guide member is provided between the bottom plate and the gear ring, the water guide member includes an inverted cone-shaped water guide portion and a tubular connecting portion, the outer periphery of the water guide portion is connected to the inner side of the shell, the connecting portion is coaxially arranged on the outer periphery of the gear ring shaft, and the connecting portion is coaxially arranged on the inner side of the first baffle ring.

[0016] With the above technical features, when water flows into the housing and contacts the water guide, the water guide guides it to the connection part, and then the water flows through the connection part to the water outlet on the inner side of the first baffle ring, and finally sprays out for cleaning. The water guide enables the water flow to be more effectively collected and guided to the water outlet. This reduces the waste and splashing of water flow and improves the utilization efficiency of water flow.

[0017] Preferably, a sealing ring is connected to the inner peripheral wall of the lower end of the shell located at the water inlet chamber, and the lower end of the sealing ring abuts and seals with the upper end of the water guide part.

[0018] With the above technical features, when water flows into the water inlet cavity through the water inlet channel, the role of the sealing ring is to ensure that the water can flow smoothly to the water guide part instead of leaking out through the gap of the shell. At the same time, the sealing ring can also prevent external impurities and dust from entering the water inlet cavity to a certain extent, keeping the internal environment clean.

[0019] Preferably, the bottom plate is coaxially connected to a water pipe on one side of the brush, the water pipe is sleeved on the outer periphery of the second retaining ring, the water pipe is connected to the lower end of the mounting shaft, and the water pipe extends away from the bottom plate.

[0020] Through the above technical features, the water pipe guides the water flow directly to the working area of ​​the brush, and the water flow sprayed from the water outlet can act more accurately on the surface to be cleaned, enhancing the impact force and cleaning effect of the water flow, making the cleaning work more efficient and thorough. In addition, the water pipe extends to one side of the brush, so the water flow can be used more directly for cleaning work, avoiding water splashing everywhere, reducing the risk of secondary pollution of the water flow, and keeping the working environment clean.

[0021] Preferably, a first bearing is provided between the impeller plate and the mounting shaft.

[0022] Through the above technical features, the first bearing is installed between the impeller plate and the mounting shaft, which supports the impeller plate and enables it to rotate freely relative to the mounting shaft, thereby ensuring the stability and precision of the impeller plate during rotation.

[0023] In summary, this application has the following beneficial effects:

[0024] (1) The present application introduces a transmission component between the impeller plate and the bottom plate. By regulating the rotation speed through the transmission component, the problems of excessive brush rotation speed, poor cleaning effect and water splashing pollution are solved, thereby improving the overall performance and user experience of the handheld cleaning device.

[0025] (2) The present application reduces the rotation speed of the bottom plate and the brush and increases the torque through the deceleration and torque-increasing effect of the multi-stage gear transmission assembly. The low-speed and high-torque operation mode enables the brush to act more effectively on the surface of the object, thereby improving the cleaning effect;

[0026] (3) In the present application, by arranging the water outlet between the first baffle ring, the second baffle ring and the connecting sleeve, the sprayed water flow will be guided by the baffle ring and flow to the area that needs to be cleaned in a more concentrated and orderly manner.

The end of the pipe 91 extending into the housing 1 is inserted into the water inlet channel 17, and a plurality of sealing rings are spaced axially between the extension section and the inner peripheral wall of the water inlet channel 17.

[0038] The partition plate 16 is provided with a connecting sleeve 43 extending away from the cover plate 9 on one side of the lower cavity space 15. The connecting sleeve 43 is arranged at the center of the partition plate 16. The lower cavity space 15 is connected to the mounting shaft 2 in the connecting sleeve 43. The mounting shaft 2 extends away from the upper cavity space 14. The outer periphery of the mounting shaft 2 is rotatably connected to the impeller shaft 3. The impeller shaft 3 is rotatably connected to the outer periphery of the mounting shaft 2 and close to the side of the mounting block 10 through the first bearing 32. The outer periphery of the impeller shaft 3 is evenly spaced along the circumference. A plurality of impeller plates 31 are evenly spaced along the circumference. Two water spray ports 13 are provided on the peripheral wall of the water inlet cavity 11 on the mounting block 10. The water spray ports 13 connect the water inlet cavity 11 and the lower cavity space 15. The water spray ports 13 spray the water in the water inlet cavity 11 vertically to the impeller plate 31 to drive the impeller plate 31 to rotate.

[0039] The bottom plate 4 is provided with a water outlet 42 , which is connected with the lower cavity space 15 and the water spray port 13 . The water spray port 13 drives the impeller plate 31 to rotate and then flows out from the water outlet 42 through the lower cavity space 15 .

[0040] like Figure 3 , Figure 4 As shown, the impeller plate 31 is connected to the base plate 4 through a transmission assembly 5. The transmission assembly 5 includes a gear ring 51, two driven wheel groups 52, and a gear ring 53 arranged on the outer periphery of the lower end of the impeller shaft 3. The two driven wheel groups 52 are meshedly connected to the outer periphery of the gear ring 51 at intervals, and the gear ring 53 is meshedly connected to the outer periphery of the driven wheel group 52. The end of the gear ring 53 away from the driven wheel group 52 is coaxially connected to a gear ring shaft 531. The gear ring shaft 531 is rotatably connected to the outer periphery of the installation shaft 2, and a second bearing 532 is provided between the gear ring shaft 531 and the installation shaft 2. The base plate 4 is coaxially connected to the gear ring shaft 531.

[0041] The driven wheel assembly 52 includes a gear fixing frame 521, a first driven wheel 522, a second driven wheel 523, a driven wheel shaft 524, and a fourth bearing 525. The gear fixing frame 521 is sleeved on the outer periphery of the lower end of the mounting shaft 2 located at the impeller shaft 3. The first driven wheel 522 is meshedly connected to the outer periphery of the gear ring 51. The driven wheel shaft 524 is connected to the axis of the first driven wheel 522. The driven wheel shaft 524 is rotatably connected to the gear fixing frame 521. The gear fixing frame 521 is provided with a rotating groove 5211 corresponding to the driven wheel shaft 524. The fourth bearing 525 is arranged between the inner circumferential wall of the rotating groove 5211 and the outer circumferential wall of the driven wheel shaft 524. The second driven wheel 523 is connected to one end of the driven wheel shaft 524 away from the first driven wheel 522. The second driven wheel 523 is meshedly connected to the gear ring 53.

[0042] like Figure 5 , Figure 6 As shown, an upwardly extending connecting sleeve 43 is provided at the center of the base plate 4. The connecting sleeve 43 is rotatably connected to the outer periphery of the mounting shaft 2 through a third bearing 44. The connecting sleeve 43 is inserted into the gear ring shaft 531. The gear ring shaft 531 directly drives the base plate 4 to rotate through the connecting sleeve 43.

[0043] The bottom plate 4 is coaxially provided with a first baffle ring 45 and a second baffle ring 46 extending upward and downward respectively on the outer periphery of the connecting sleeve 43. The water outlet 42 is arranged between the first baffle ring 45, the second baffle ring 46 and the connecting sleeve 43. The baffle rings reduce the splashing and diffusion of water during the spraying process, thereby maintaining a clean environment.

[0044] A water guide member 6 is provided between the bottom plate 4 and the gear ring 53. The water guide member 6 includes an inverted cone-shaped water guide portion 61 and a tubular connecting portion 62. The outer periphery of the water guide portion 61 is connected to the inner side of the shell 1. The connecting portion 62 is coaxially arranged on the outer periphery of the gear ring shaft 531. The connecting portion 62 is coaxially arranged on the inner side of the first baffle ring 45.

[0045] The inner peripheral wall of the lower end of the housing 1 located in the water inlet chamber 11 is connected with a sealing ring 7, the upper end of the sealing ring 7 is sealed with the mounting block 10, and the lower end of the sealing ring 7 is abutted and sealed with the upper end of the water guide 61. The sealing ring 7 ensures that the water can flow smoothly to the water guide 61 instead of leaking out through the gap between the mounting block 10 and the housing 1.

[0046] The bottom plate 4 is coaxially connected to a water pipe 8 on one side of the brush 41. The water pipe 8 is sleeved on the outer periphery of the second retaining ring 46. The water pipe 8 is connected to the lower end of the mounting shaft 2. The water pipe 8 extends away from the bottom plate 4. The water pipe 8 directly guides the water flow to the working area of ​​the brush 41. The water flow sprayed from the water outlet 42 can more accurately act on the surface to be cleaned, enhancing the impact force and cleaning effect of the water flow, making the cleaning work more efficient and thorough. In addition, the water pipe 8 extends to one side of the brush 41, so that the water flow can be used more directly for cleaning work, avoiding the splashing of the water flow, reducing the risk of secondary pollution of the water flow, and keeping the working environment clean.

[0047] Working principle: When water flows through the water nozzle 13 and is sprayed onto the impeller plate 31, the impeller plate 31 begins to rotate around the impeller shaft 3 due to the impact of the water flow, and the gear ring 51 at the lower end of the impeller shaft 3 rotates synchronously. The outer periphery of the gear ring 51 is meshedly connected with at least two driven wheel groups 52, which are arranged at intervals and transmit power through the meshing between gears. Since the gear transmission has the characteristics of deceleration and torque increase, as the power is transmitted from the gear ring 51 to the driven wheel group 52, the speed gradually decreases and the torque gradually increases. The outer periphery of the driven wheel group 52 is meshedly connected with a gear ring 53, which continues to transmit the power after multiple stages of deceleration to the gear ring shaft 531. The gear ring shaft 531 is coaxially connected to the bottom plate 4, and transmits the power to the bottom plate 4, driving the bottom plate 4 and the brush 41 thereon to rotate. Through the deceleration and torque-increasing effect of the multi-stage gear transmission assembly 5, the rotation speed of the base plate 4 and the brush 41 is reduced and the torque is increased. The low-speed and high-torque operation mode enables the brush 41 to act on the surface of the object more effectively, thereby improving the cleaning effect.

[0048] During the washing process, water flows into the lower cavity space 15 through the water spray port 13. The sealing member avoids leakage in the gap of the water delivery shell 1, ensuring that the water can flow into the water guide portion 61 of the guide member, and then flows to the water outlet 42 of the bottom plate 4 through the connecting portion 62, and flows out through the water guide pipe 8, thereby avoiding water splashing around during the cleaning process and keeping the working environment clean.

[0049] The specific embodiments described herein are merely examples of the present application. A person skilled in the art of the present application may make various modifications or additions to the specific embodiments described or replace them in a similar manner without departing from the scope defined in the present application.
