Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a wringer disc and a mop bucket. Background Technology

[0002] Spin mops are convenient for washing and wringing, and especially can achieve the cleaning effect of a semi-dry mop. They are becoming increasingly widely used in daily life. Their most basic principle is to make the disc at the bottom of the mop rotate with the spin-drying basket or washing disc in the wringing bucket, thereby achieving the functions of centrifugal dehydration or mop washing.

[0003] Because low-speed rotation is needed during washing to prevent splashing, and high-speed rotation is needed during spin-drying to increase centrifugal force, dual-speed spin mops are becoming increasingly common in the market. These mops utilize planetary gear transmission mechanisms to meet this need. To address the issue of gear ratio switching, some products on the market employ a locking mechanism between the mop head and the handle. This mechanism uses a clutch to lock the mop disc handle head and the outer wheel on which the mop pad is mounted, thus disabling the planetary gear reduction structure and achieving high-speed rotation of the mop head during spin-drying. However, this clutch structure is complex, has many parts, and is prone to damage. Furthermore, the spring used to trigger the clutch has a small diameter and is prone to slippage due to poor contact during use, leading to locking failure and reduced spin-drying efficiency.

[0004] Therefore, it is necessary to develop a water-spinning mop disc and mop bucket to address the aforementioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a spin mop disc and mop bucket that can switch between washing and spin drying speeds simply by locking the planetary disc and sun wheel respectively. The structure is simple and the operation is stable.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a spin-dry mop disc and mop bucket, comprising a mop handle head, a sun wheel assembly, a wheel disc retainer, a planetary wheel disc, planetary gears, and an outer wheel disc. The mop handle head is pinned to a plug at the top of the sun wheel assembly. The planetary wheel disc is coaxially and rotatably mounted below the sun wheel assembly via the wheel disc retainer. The outer wheel disc is coaxially and rotatably sleeved on the outside of the sun wheel assembly. The planetary gears are driven between the sun gear teeth of the sun wheel assembly and the external gears on the inner side of the outer wheel disc. The bottom of the outer wheel disc is connected to the mop cloth via a snap-fit ​​mechanism. Multiple planetary gears are rotatably connected to a planetary gear axle on the top of the planetary wheel disc. A cleaning socket for connecting the cleaning seat plug of the mop bucket is provided at the center of the bottom of the planetary wheel disc. A lower connector is coaxially provided at the bottom of the sun wheel assembly, which can be coaxially inserted into the top of the central column of the mop bucket spin-dry basket.

[0008] By using the lower connector to coaxially insert into the top hole of the central column of the mop bucket spin dryer basket, the two can be coaxially connected and circumferentially locked, and the torque can be directly transmitted to the mop bucket spin dryer basket, driving the mop bucket spin dryer basket to rotate at high speed to dehydrate.

[0009] Furthermore, the wheel clamp is a cylindrical structure with claws. The inner folded edge at the top of the wheel clamp is engaged with the outer folded edge at the bottom of the sun wheel. The bottom of the wheel clamp is provided with four claws, which are engaged in the clamping holes of the planetary wheel.

[0010] Furthermore, the lower connector is a four-tooth spline plug, the cleaning socket is a four-tooth spline hole, and the inner diameter of the cleaning socket is larger than the outer diameter of the lower connector.

[0011] Compared to square-headed connectors, four-tooth splined connectors can transmit greater torque and are less prone to deformation and damage.

[0012] Furthermore, the top of the lower connector is a coaxially connected lower positioning post, and the sleeve at the top of the planetary disk is inserted between the lower positioning post and the inner wall of the central hole of the sun gear component.

[0013] This utility model also discloses a mop bucket, which is used in conjunction with the spin mop disc described in any of the above-mentioned claims.

[0014] Furthermore, it includes a mop bucket body, a spin-dry basket, and a spin-dry locking post. The spin-dry basket is rotatably disposed in the spin-drying area of ​​the mop bucket body via a pivot. The spin-dry locking post is fixedly connected to the middle position of the bottom of the spin-dry basket. A spin-drying slot is provided at the center of the top of the spin-dry locking post, and the lower connector can be inserted into the spin-drying slot and locked circumferentially.

[0015] Furthermore, the cross-sectional profile of the spin-dry slot is a four-tooth spline hole and is adapted to the lower connector; the outer diameter of the top of the spin-dry locking post is smaller than the inner diameter of the cleaning socket.

[0016] Furthermore, the cleaning seat plug is vertically disposed in the cleaning area of ​​the mop bucket body, and the cross-sectional profile of the cleaning seat plug is a four-tooth spline that fits into the cleaning socket; the top of the cleaning seat plug is a ball head, and the ball head abuts against the bottom end face of the lower connector.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] This utility model features a spin-dry mop disc and mop bucket. By incorporating a cleaning socket that engages with the cleaning seat plug, the planetary gear disc can be locked, ensuring the normal operation of the planetary gear reduction mechanism. This drives the outer disc to rotate slowly, preventing water splashing during washing. A lower connector coaxially plugs into the top of the spin-dry basket's central column, locking the sun gear and spin-dry basket, which then rotates rapidly to centrifugally dry the mop cloth. Compared to the complex locking methods in existing technologies, this utility model's spin-dry mop disc only requires locking the planetary gear disc and sun gear separately to achieve speed switching between washing and spin-drying, resulting in a simple structure and stable operation.

[0019] Furthermore, the claws of the wheel disc clamp engage with the locking holes of the planetary wheel disc, enabling rapid coaxial assembly of the planetary wheel disc and the wheel disc clamp. The blocking protrusions and blocking side plates prevent the planetary wheel disc from detaching from the wheel disc clamp. The flanged outer ring of the planetary wheel disc closes the bottom edge of the external gear, preventing debris from entering the planetary gear's operating cavity and avoiding its entanglement. The insertion hole allows for secure connection to the mop handle by fitting it onto the bottom of the mop handle and tightening it with a screw-on sleeve. With the addition of a sleeve head and a positioning clip, when the mop handle head and mop handle are coaxial, the pressure protrusion of the positioning clip pushes downwards to press against the sleeve head base, and the oblong hole presses the pin into the pin hole, achieving effective connection between the mop handle head and the sun gear. The top sleeve of the planetary wheel disc fits onto the lower positioning post with a rotatable clearance fit, ensuring the coaxial connection between the planetary wheel disc and the sun gear.

[0020] This utility model of a mop bucket achieves coaxial circumferential locking by creating a spin-drying slot at the top of the spin-drying locking post and inserting a lower connector. This allows the torque of the mop handle to be directly transmitted to the spin-drying locking post via the sun gear, thus achieving synchronous rotation of the spin-drying basket. A support platform, as shown in the figure, is coaxially driven by the spin-drying locking post with external ribs, ensuring the spin-drying basket rotates synchronously. Rounded chamfers at the insertion ends of the spin-drying slot and lower connector facilitate smooth insertion after guidance. Setting the outer diameter of the top of the spin-drying locking post to be smaller than the inner diameter of the cleaning socket prevents interference between the cleaning socket and the top of the spin-drying locking post during insertion, reducing resistance. The ball-shaped tip of the cleaning seat plug reduces wear on the lower connector; the extended design of the lower connector also increases wear resistance and extends the lifespan of the mop disc.

[0034] Example 1

[0035] In one specific implementation, such as Figures 1-4 As shown, the present invention relates to a water-spinning mop disc, comprising a mop handle head 1, a sun gear 2, a disc retainer 3, a planetary disc 4, planetary gears 5, and an outer disc 6. The mop handle head 1 is pinned to a plug at the top of the sun gear 2. The planetary disc 4 is rotatably mounted coaxially below the sun gear 2 via the disc retainer 3. The outer disc 6 is rotatably mounted coaxially on the outside of the sun gear 2, and the planetary gears 5 are connected to the sun gear teeth 201 of the sun gear 2 and the external gear 601 on the inner side of the outer disc 6. A ring is added to the bottom of the outer disc 6 to attach a ring-shaped mop cloth. Multiple planetary gears 5 are rotatably connected to a planetary gear axle on the top of the planetary disc 4; in one specific embodiment, there are three planetary gears 5. A cleaning socket 401 for connecting the cleaning seat plug of the mop bucket is provided at the center of the bottom of the planetary disc 4. The bottom end of the sun wheel component 2 is coaxially provided with a lower insertion connector 203, which can be coaxially inserted into the top of the central column of the mop bucket spin dryer basket.

[0036] By setting the cleaning socket 401 in conjunction with the cleaning seat plug, the planetary gear disk 4 can be locked, enabling the planetary gear reduction mechanism to work normally and drive the outer wheel disk 6 to rotate slowly, avoiding water splashing during the cleaning process. By setting the lower connector 203 to be coaxially inserted into the top of the central column of the spin-drying basket, the sun gear component 2 and the spin-drying basket can be locked, thereby causing the spin-drying basket to rotate rapidly and centrifugally dry the mop cloth. Compared with the complex locking methods in the prior art, the spin-drying mop disc of this utility model only needs to lock the planetary gear disk and the sun gear component separately to achieve the speed switching between cleaning and spin-drying, with a simple structure and stable operation.

[0037] In one specific implementation of this embodiment, such as Figure 1 and Figure 2As shown, the planetary disk retainer 3 is a cylindrical structure with claws. The inner folded edge at the top of the planetary disk retainer 3 is engaged with the outer folded edge at the bottom of the sun gear 2 to prevent the planetary disk 4 from axially disengaging downwards. The bottom of the planetary disk retainer 3 is provided with four claws, which are evenly distributed and spaced around the circumference. The claws engage with the retaining holes of the planetary disk 4.

[0038] Specifically, such as Figure 1 and Figure 2 As shown, the planetary gear 4 has a blocking protrusion at the position of the pawl, and blocking side plates on both sides to prevent circumferential rotation. The outer ring of the planetary gear 4 has an upward-facing flange that closes the bottom edge of the external gear 601.

[0039] The claws of the wheel disc retainer 3 engage with the retaining holes of the planetary wheel disc 4, enabling rapid coaxial assembly of the planetary wheel disc 4 and the wheel disc retainer 3. The blocking protrusions and blocking side plates prevent the planetary wheel disc 4 from detaching from the wheel disc retainer 3. The flanged outer ring of the planetary wheel disc 4 seals the bottom edge of the external gear 601, preventing debris from entering the planetary gear operating cavity and avoiding the interference of entangled debris.

[0040] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the mop handle head 1 includes a handle fork head body and a tightening sleeve 101. The top of the handle fork head body is provided with an insertion hole with a slotted side wall. The tightening sleeve 101 is threaded onto the external thread on the outer wall of the insertion hole. The insertion hole is fitted onto the bottom end of the mop handle and locked by the tightening sleeve 101.

[0041] Specifically, such as Figures 1-5 As shown, the mop handle head 1 also includes a positioning clip 102 and a sleeve head 103. The sleeve head 103 has a thin-shell structure, and its upper part is fitted onto the plug at the top of the sun gear component 2. The upper part of the sleeve head 103 has a vertically arranged oblong hole. The fork head of the handle body is connected to the oblong hole and the pin hole of the plug of the sun gear component 2 by a pin. The positioning clip 102 is installed at both ends of the pin by countersunk screws, and the positioning clip 102 can be rotated circumferentially by being turned by the fork head of the handle body. The side wall of the fork head of the handle body has a receiving groove, and the side wall of the positioning clip 102 facing the fork head has a protrusion that engages with the receiving groove. The bottom of the positioning clip 102 has a pressing block protrusion that presses against the base of the sleeve head 103.

[0042] The mop head 1 is connected to the bottom of the mop handle through the insertion hole and locked by the tightening sleeve 101, which can effectively connect to the mop handle. By adding the sleeve head 103 and the positioning clip head 102, when the mop head 1 and the mop handle are coaxial, the pressure block protrusion of the positioning clip head 102 pushes down to press the base of the sleeve head 103, and the waist-shaped hole presses the pin in the pin hole, thus realizing the effective connection between the mop head 1 and the sun wheel component 2.

[0043] In one specific implementation of this embodiment, such as Figures 1-4 As shown, the lower connector 203 is a four-tooth spline plug, and the cleaning socket 401 is a four-tooth spline hole. The inner diameter of the cleaning socket 401 is larger than the outer diameter of the lower connector 203.

[0044] Obviously, the cross-sectional contours of the lower connector 203 and the cleaning socket 401 can also be square or other polygons, as long as circumferential locking is possible. Similar simple replacement methods all fall within the protection scope of this utility model.

[0045] In one specific embodiment of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, the top of the lower connector 203 is a coaxially connected lower positioning post 202, which is in the form of an optical axis. The sleeve on the top of the planetary disk 4 is inserted between the lower positioning post 202 and the inner wall of the central hole of the sun gear 2.

[0046] The planetary disk 4 is fitted onto the lower positioning post 201 with a top sleeve, allowing for a rotatable clearance fit, which ensures the coaxial connection between the planetary disk 4 and the sun gear 2.

[0047] In summary, the present invention's spin-dry mop disc, by setting a cleaning socket 401 in conjunction with the cleaning seat plug, can lock the planetary wheel 4, enabling the planetary gear reduction mechanism to work normally and drive the outer wheel 6 to rotate slowly, avoiding water splashing during the washing process; by setting a lower connector 203 to be coaxially inserted into the top of the central column of the spin-dry basket, the sun wheel 2 and the spin-dry basket can be locked, thereby causing the spin-dry basket to rotate rapidly and centrifugally spin-dry the mop cloth. Compared with the complex locking methods in the prior art, the present invention's spin-dry mop disc only needs to lock the planetary wheel and the sun wheel separately to achieve the switching of washing and spin-drying speeds, with a simple structure and stable operation. In addition, by the claws of the wheel disc retainer 3 engaging into the retaining holes of the planetary wheel 4, the planetary wheel 4 and the wheel disc retainer 3 can be quickly and coaxially assembled. The setting of the blocking protrusion and the blocking side plate prevents the planetary wheel 4 from detaching from the wheel disc retainer 3. By flanging the outer ring of the planetary gear disk 4 and sealing the bottom edge of the external gear 601, debris can be prevented from entering the planetary gear operating cavity, avoiding the influence of debris entanglement. The disk is fitted onto the bottom end of the mop handle through the insertion hole and locked by the tightening sleeve 101, effectively connecting it to the mop handle. With the addition of a sleeve head 103 and a positioning clip 102, when the mop handle head 1 and the mop handle are coaxial, the pressure block protrusion of the positioning clip 102 pushes downward to press against the base of the sleeve head 103, and the oblong hole presses the pin into the pin hole, achieving effective connection between the mop handle head 1 and the sun gear component 2. The top sleeve of the planetary gear disk 4 is fitted onto the lower positioning post 201, with a rotatable clearance fit, ensuring the coaxial connection between the planetary gear disk 4 and the sun gear component 2.

[0048] Example 2

[0049] This utility model also discloses a mop bucket, such as Figure 5 As shown, it is used in conjunction with the wringer disc of any of the above embodiments.

[0050] like Figures 5-7 As shown, the mop bucket of this utility model includes a mop bucket body 7, a spin-dry basket 8, and a spin-dry locking post 9. The spin-dry basket 8 is rotatably disposed in the spin-drying area of ​​the mop bucket body 7 via a pivot. The spin-dry locking post 9 is fixedly connected to the bottom center of the spin-dry basket 8 and is vertically arranged. A spin-drying slot 901 is centrally located at the top of the spin-drying locking post 9, and a lower connector 203 can be inserted into the spin-drying slot 901 and locked circumferentially.

[0051] By opening a spin-drying slot 901 at the top of the spin-drying locking post 9 and inserting a lower connector 203, coaxial circumferential locking can be achieved, so that the torque of the mop handle head 1 is directly transmitted to the spin-drying locking post 9 through the sun gear 2, thereby realizing the synchronous rotation of the spin-drying basket 8.

[0052] Specifically, such as Figures 5-7As shown, the base of the spin-drying locking post 9 is fixedly connected to the support platform 801, and the central hole of the spin-drying locking post 9 is rotatably connected to the top of the rotating shaft. The bottom edge of the support platform 801 is fixedly connected to the central hole of the spin-drying basket 8.

[0053] Specifically, the support platform 801 is provided with multiple circumferentially distributed outer ribs 902, which are embedded in the slots corresponding to the central holes of the support platform 801.

[0054] By adding a support platform 801, such as Figure 7 As shown, the support platform 801 is coaxially driven by the spin-drying locking column 9 with external ribs 902, ensuring that the spin-drying basket 8 rotates synchronously.

[0055] Specifically, such as Figures 5-7 As shown, the cross-sectional profile of the spin-dry slot 901 is a four-tooth spline hole that is adapted to the lower connector 203. Both the top edge of the spin-dry slot 901 and the bottom edge of the lower connector 203 have rounded chamfers. The outer diameter of the top of the spin-dry locking post 9 is smaller than the inner diameter of the cleaning socket 401.

[0056] Obviously, the cross-sectional profile of the spin-dry slot 901 can also be a square or other polygon, as long as circumferential locking is possible. Similar simple replacement methods all fall within the protection scope of this utility model.

[0057] By providing smooth chamfers at the insertion ends of the spin-dry slot 901 and the lower connector 203, smooth insertion after guidance is facilitated. The outer diameter of the top of the spin-dry locking post 9 is set to be smaller than the inner diameter of the cleaning socket 401, which avoids interference between the cleaning socket 401 and the top of the spin-dry locking post 9 during the insertion process and reduces the resistance during the insertion process.

[0058] In one specific embodiment of this utility model, such as Figure 5 As shown, the cleaning seat plug is vertically positioned in the cleaning area of ​​the mop bucket body 7. The cross-sectional profile of the cleaning seat plug is a four-tooth spline, which fits into the cleaning socket 401. The top of the cleaning seat plug is a ball head, which abuts against the bottom end face of the lower connector 203.

[0059] The top of the cleaning seat plug is a ball head, which reduces wear on the lower connector 203; the extended design of the lower connector 203 also increases wear resistance and improves the service life of the mop disc.

[0060] The working principle of this utility model's spin-dry mop disc and mop bucket is as follows: When the cleaning socket 401 is inserted into the cleaning seat plug of the mop bucket, because the cleaning seat plug is fixed, the planetary gear disc 4 is stuck and cannot rotate. The mop handle drives the mop head 1 to rotate, the mop head 1 drives the sun gear 2 to rotate, and the sun gear 2 drives the planetary gear 5 to rotate on its own axis. At this time, the planetary gear 5 does not revolve around the sun. At this time, the external gear 601 is driven to rotate by the planetary gear 5, and the external disc 6 rotates slowly. Since the number of teeth of the external gear 601 is greater than the number of teeth of the sun gear 2, the ratio of their tooth numbers is the reduction ratio at this time. Ultimately, the mop cloth is driven to rotate at a low speed in the cleaning area, achieving a labor-saving washing effect without splashing water. The disc is moved into the spin-dry basket 8, completing the coaxial connection and circumferential locking of the sun gear 2 and the spin-dry locking post 9. The torque of the mop head 1 is directly transmitted to the spin-dry locking post 9 through the sun gear 2, thereby achieving synchronous rotation of the spin-dry basket 8. Because the mop cloth is clamped between the side wall of the spin-drying basket 8 and the outer wheel 6, the outer wheel 6 cannot rotate relative to the planetary wheel 3. Since the two cannot rotate relative to each other, the planetary wheel 5 will not rotate, and the planetary wheel reduction mechanism will not work. The mop handle 1 drives the spin-drying basket 8 to rotate synchronously at high speed, performing centrifugal spin-drying of the mop cloth.

[0061] In summary, this utility model of a mop bucket, by providing a spin-drying slot 901 at the top of the spin-drying locking post 9 and inserting a lower connector 203, achieves coaxial circumferential locking, allowing the torque of the mop handle head 1 to be directly transmitted to the spin-drying locking post 9 via the sun gear 2, thereby achieving synchronous rotation of the spin-drying basket 8. By adding a support platform 801, such as... Figure 7 As shown, the support platform 801 is coaxially driven by the spin-drying locking post 9 with external ribs 902, ensuring that the spin-drying basket 8 rotates synchronously. Smooth chamfers are provided at the insertion ends of the spin-drying slot 901 and the lower connector 203 to facilitate smooth insertion after guidance. The outer diameter of the top of the spin-drying locking post 9 is set smaller than the inner diameter of the cleaning socket 401 to avoid interference between the cleaning socket 401 and the top of the spin-drying locking post 9 during insertion, reducing resistance during the insertion process. The top of the cleaning seat plug is a ball head, reducing wear on the lower connector 203; the extended design of the lower connector 203 also increases wear resistance and improves the service life of the mop disc.
