A clutch-type rotary mop cleaning tool

Abstract

This invention provides a clutch-type rotary mop cleaning tool, including a mop and a mop bucket. A rotary water spray device is installed inside the mop bucket, and an impeller clutch is fitted around the outside of the rotary water spray device. The impeller clutch can slide up and down relative to the rotary water spray device. An impeller portion is located at the bottom of the impeller clutch. When the mop disc rotates at high speed in conjunction with the impeller clutch, the impeller clutch slides upward relative to the rotary water spray device under the thrust generated by the impeller portion. When the mop disc rotates at low speed, the impeller clutch is in a low position, and the rotary water spray device sprays water for cleaning. When the mop disc rotates at high speed, the impeller clutch is raised to a high position, disengaging the rotary water spray device or closing the water inlet of the rotary water spray device, causing the rotary water spray device to stop rotating or idle, while the wiped items are spun dry at high speed. This clutch-type rotary mop cleaning tool overcomes the shortcomings of existing rotary mop cleaning tools, such as complex structure, inconvenient operation, and inability to clean as needed.

Description

Technical Field

[0001] This invention relates to the field of cleaning tools, and in particular to a clutch-type rotary mop cleaning tool. Background Technology

[0002] Spin mops are among the most popular cleaning products due to their ease of use and excellent wringing effect. To improve the user experience of spin mops, single-bucket spin mops and spin mops with separate cleaning and wringing functions have been introduced to the market. Currently, the main issue affecting the user experience of single-bucket spin mops is the switching between cleaning and wringing. These typically use methods such as adjusting the mop height or setting multiple water tanks to achieve this switching, but these methods often suffer from difficulties in operation, complex structures, or the inability to clean as needed.

[0003] For example, CN112716405A discloses a single-bucket rotary mop set, which uses a sliding centrifugal component on the mop board to control its height, thereby switching between washing and wringing. However, this height-switching mechanism results in a complex mop structure, making the mop less lightweight and thin, and the sliding centrifugal component is prone to damage during mopping. CN201710332872.1 discloses a water-saving mop bucket with multiple cavities. A clean water chamber formed by a water pump is used to complete washing and wringing in one operation. However, this structure with multiple cavities is complex, and the amount of water used for washing is fixed, making it impossible to wash as needed. For example, CN107684406A discloses a cleaning method for a cleaning tool and a cleaning tool using this method. The mop bucket is equipped with a clean water area and a dirty water area. The clean water area is used to draw clean water to clean the wiping object. The structure has a high positioning point and a low positioning point on the central axis to realize the switching between mop cleaning and wringing. This structure is inconvenient to operate and complex, and is inconvenient to use. Summary of the Invention

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0038] Example 1:

[0039] See Figures 1 to 8 This embodiment provides a clutch-type rotary mop cleaning tool, including a mop 1 and a mop bucket 2 used in conjunction with the mop 1.

[0040] See Figure 1 and Figure 2 The mop 1 includes a mop disc 11, a mop handle 12 hinged to the mop disc 11, and a wiping material 13. The mop disc 11 is provided with a drive unit 111. The mop handle 12 is a twisted handle structure, which can drive the mop disc 11 to rotate. The drive unit 111 is used to drive the rotating water spray device to rotate.

[0041] See Figures 4 to 6 The mop bucket 2 is equipped with a rotating water spray device, and the drive unit 111 can engage and drive the rotating water spray device. An impeller clutch 3 is fitted onto the outside of the rotating water spray device, and the impeller clutch 3 can slide up and down relative to the rotating water spray device. An impeller portion 31 is located at the bottom of the impeller clutch 3, and multiple blades are evenly spaced along the circumference of the impeller portion 31. When the mop disc 11 rotates at high speed in conjunction with the impeller clutch 3, the thrust on the impeller portion 31 increases. When the thrust exceeds the weight of the impeller clutch 3, the impeller clutch 3 slides upward relative to the rotating water spray device under the thrust generated by the impeller portion 31.

[0042] See Figure 6 and Figure 7 The outer wall of the rotating water spray device is provided with multiple first stops 221 at equal intervals in a ring, and the impeller clutch 3 is provided with multiple second stops 32 at equal intervals in a ring, which cooperate with the first stops 221. When the mop disc 11 rotates at low speed, the impeller clutch 3 is in the low position, and the positions of the first stops 221 and the second stops 32 correspond. At this time, the mop disc 11 can rotate and spray water through the impeller clutch 3. When the mop disc 11 rotates at high speed, the impeller clutch 3 is in the high position, and the first stops 221 and the second stops 32 disengage. At this time, the impeller clutch 3 disconnects the rotating water spray device, and the mop disc 11 cannot rotate and spray water through the impeller clutch 3.

[0043] See Figures 4 to 6 A drive unit 4 is installed on the upper side of the rotating water spray device. The impeller clutch 3 is slidably mounted on the drive unit 4. The drive unit 111 is linked to the impeller clutch 3 through the drive unit 4. Multiple sliders 41 are spaced apart along the circumferential direction at the lower end of the drive unit 4. Multiple vertical grooves 34 are provided on the impeller clutch 3 to cooperate with the sliders 41. The sliders 41 are placed in the vertical grooves 34 to guide the impeller clutch 3. The drive unit 4 is provided with a limiting flange 42 for limiting the impeller clutch 3. When the impeller clutch 3 slides upward, the limiting flange 42 can limit the impeller clutch 3.

[0044] See Figure 2 and Figure 5 The drive unit 111 has multiple third stops 112 arranged in a ring at intervals, and the drive member 4 has multiple fourth stops 43 arranged in a ring at intervals to cooperate with the third stops 112. The drive unit 111 can be engaged with the drive member 4. Through the cooperation of the third stops 112 and the fourth stops 43, the drive member 4 is driven to rotate, which in turn drives the impeller clutch 3 to rotate. Then, through the clutch action of the impeller clutch 3 sliding up and down, the rotating water spray device is controlled to rotate to spray water or stop rotating.

[0045] See Figures 4 to 6 The rotary water spray device includes a support shaft 21 and a water-driving impeller pump 22 rotatably mounted on the outside of the support shaft 21. The bottom of the water-driving impeller pump 22 has multiple blades for pumping water. An impeller clutch 3 is fitted onto the outside of the water-driving impeller pump 22. A first stop block 221 is located at the upper end of the water-driving impeller pump 22. The rotary water spray device is controlled to spray water or stop by interlocking or disconnecting the water-driving impeller pump 22 through the impeller clutch 3. A bearing 5 is installed inside the drive component 4, and a positioning component 6 is installed inside the water-driving impeller pump 22. The upper end of the support shaft 21 is connected to the bearing 5, and the middle part is connected to the positioning component 6.

[0046] See Figure 1 , Figure 3 and Figure 4 The mop bucket 2 is equipped with a clean water zone 201 and a wastewater zone 202. A rotating water spray device is installed in the clean water zone 201. A cleaning disc 24 covers the clean water zone 201. One end of the drive unit 4 passes through the cleaning disc 24 to facilitate engagement with the drive unit 111. The cleaning disc 24 is equipped with a water spray component 25 and a cleaning component 26. The water spray component 25 is connected to the rotating water spray device, and the cleaning component 26 is a brush or scraper. The clean water zone 201 is located at the center of the mop bucket 2, and the wastewater zone 202 is arranged around the outer circumference of the clean water zone 201. The upper end of the mop bucket 2 is equipped with a water inlet 203, and the lower end is equipped with a water outlet 204. The water inlet 203 connects to the clean water zone 201, and the water outlet 204 connects to the wastewater zone 202.

[0047] In use, the mop 1 is installed on the mop bucket 2, the drive unit 111 engages with the drive component 4, and when the mop disc 11 rotates at low speed, the mop disc 11 drives the impeller clutch 3 to rotate through the drive component 4. Since the thrust on the impeller part 31 is less than its own weight, the impeller clutch 3 is in a low position. At this time, the first stop 221 and the second stop 32 are in corresponding positions, and the impeller clutch 3 is linked to the water-driving impeller pump 22 of the rotating water spray device. The water spray component 25 sprays water to rinse the wiped object, and at the same time, the cleaning component 26 cleans the wiped object. When the mop disc 11 rotates at high speed, the impeller clutch 3 is raised to a high position under the action of the thrust. At this time, the first stop 221 and the second stop 32 are misaligned, and the impeller clutch 3 disconnects the water-driving impeller pump 22 of the rotating water spray device, so that the rotating water spray device stops rotating. The rotating water spray device stops spraying water, and the wiped object 13 rotates at high speed to spin dry.

[0048] Example 2:

[0049] See Figures 9 to 13 This embodiment provides a clutch-type rotary mop cleaning tool, including a mop 1 and a mop bucket 2 used in conjunction with the mop 1. The mop 1 is exactly the same as that in Embodiment 1.

[0050] See Figures 10 to 12 The mop bucket 2 is equipped with a rotating water spray device, and the drive unit 111 can engage and drive the rotating water spray device. An impeller clutch 3 is fitted onto the outside of the rotating water spray device. The impeller clutch 3 can slide up and down relative to the rotating water spray device, but the two cannot rotate relative to each other. An impeller portion 31 is located at the bottom of the impeller clutch 3, and multiple blades are evenly spaced along the circumference of the impeller portion 31. When the mop disc 11 rotates at high speed in conjunction with the impeller clutch 3, the thrust on the impeller portion 31 increases. When the thrust exceeds the weight of the impeller clutch 3, the impeller clutch 3 slides upward relative to the rotating water spray device under the thrust generated by the impeller portion 31.

[0051] See Figure 12 and Figure 13The outer wall of the rotating water spray device is provided with multiple water inlets 231 arranged in a ring, and the impeller clutch 3 is provided with multiple water passage holes 33 arranged in a ring at equal intervals to cooperate with the water inlets 231. When the mop disc 11 rotates at low speed, the impeller clutch 3 is in a low position, the water passage holes 33 correspond to the water inlets 231, the water inlets 231 are open, and the rotating water spray device can spray water. When the mop disc 11 rotates at high speed, the impeller clutch 3 is in a high position, the water passage holes 33 are offset from the water inlets 231, the water inlets 231 are closed, and the rotating water spray device idles without spraying water.

[0052] See Figure 10 and Figure 12 The rotary water spray device includes a support shaft 21, a water-driving impeller pump 22 rotatably mounted on the outside of the support shaft 21, and an outer casing 23 mounted on the outside of the water-driving impeller pump 22. An impeller clutch 3 is slidably mounted on the outer casing 23, and a water inlet 231 is located on the outer casing 23. A transmission component 7 is mounted on the upper end of the water-driving impeller pump 22, and baffles 71 are symmetrically arranged on both sides of the transmission component 7. The impeller clutch 3 is provided with a sliding groove 35 that cooperates with the baffles 71. The water-driving impeller pump 22 can rotate in conjunction with the impeller clutch 3 through the cooperation of the baffles 71 and the sliding groove 35.

[0053] See Figure 11 and Figure 12 The drive unit 111 can engage with the water-driving impeller pump 22. Multiple third stops 112 are evenly spaced in a ring within the drive unit 111. Multiple fourth stops 43, which cooperate with the third stops 112, are spaced in a ring at the upper end of the water-driving impeller pump 22. The drive unit 111 can drive the water-driving impeller pump 22 and the impeller clutch 3 to rotate through the cooperation of the three stops 112 and the fourth stops 43. The water-driving impeller pump 22 has a sliding sleeve 8 at its upper end and a bearing 5 in its middle section; the support shaft 21 is connected to the sliding sleeve 8 at its upper end and to the bearing 5 in its middle section.

[0054] See Figure 9 and Figure 10 The mop bucket 2 is equipped with a clean water zone 201 and a wastewater zone 202. A rotating water spray device is installed in the clean water zone 201. A cleaning disc 24 covers the clean water zone 201. The upper end of the water-driving impeller pump 22 passes through the cleaning disc 24 to facilitate engagement with the drive unit 111. The cleaning disc 24 is equipped with a water spray component 25 and a cleaning component 26. The water spray component 25 is connected to the rotating water spray device. The clean water zone 201 is located at the center of the mop bucket 2, and the wastewater zone 202 is arranged around the outer circumference of the clean water zone 201. The mop bucket 2 has a water inlet 203 at the upper end and a water outlet 204 at the lower end. The water inlet 203 connects to the clean water zone 201, and the water outlet 204 connects to the wastewater zone 202.

[0055] In use, the mop 1 is installed on the mop bucket 2, and the drive unit 111 engages with the water-driving impeller pump 22. When the mop disc 11 rotates at low speed, the mop disc 11 is linked to the water-driving impeller pump 22 and the impeller clutch 3 to rotate. Since the weight of the impeller clutch 3 is greater than the thrust, the impeller clutch 3 is in a low position. At this time, the water passage 33 corresponds to the water inlet 231, the water inlet 231 is open, and the water-driving impeller pump 22 can pump water to rinse the wiped object 13. When the mop disc 11 rotates at high speed, the thrust on the impeller clutch 3 is greater than its own weight. Under the action of the thrust, the impeller clutch 3 is raised to a high position. At this time, the water passage 33 is misaligned with the water inlet 231, the water inlet 231 is closed, the water-driving impeller pump 22 runs idle, the rotating water spray device stops spraying water, and the wiped object 13 rotates at high speed to spin dry.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
