Description

Technical Field

[0001] The invention belongs to the technical field of cleaning tools, in particular to a cleaning tool. Background Art

[0002] Mops are a necessity in daily life, and more and more are appearing on the market. However, flat mops remain the mainstream product, and their advantage of a large wiping surface is widely recognized. Cleaning tools with centrifugal rotary dehydration have emerged on the market, such as Chinese Patent CN201320830364.3, a cleaning tool and a rotary mop thereof. These use a compressed, rotating mop rod. After the mop head is suspended in the air, the mop rod is pressed down, causing the wipes on the mop head to undergo centrifugal dehydration. Alternatively, as in Chinese Patent CN 201621152336.0, during dehydration, the mop head is first bent at both ends and placed in the dehydration area of ​​the mop bucket. The mop rod is then pressed down, causing the wipes on the mop head to undergo centrifugal dehydration. The above method utilizes the downward rotational force of the mop rod, changing the traditional method of squeezing the wipes with a relatively moving scraper, making the operator more labor-saving. However, the mop bucket structure, mop head structure, and the mop head and mop bucket matching structure of the above method are extremely complex, and the production cost is high. Summary of the Invention

A positioning protrusion is arranged on the support seat, and the positioning protrusion can be maintained on the low limit part / high limit part; when the positioning protrusion is located on the low limit part, the support seat is located at the low position of the mop bucket; when the positioning protrusion is located on the high limit part, the support seat is located at the high position of the mop bucket.

[0012] At least one pair of tracks is provided on both sides of the mop bucket, and the positioning protrusions move within the tracks, and a low limit portion and a high limit portion are provided within the tracks; and the hinged seat of the mop head is clamped with the positioning seat; when the mop is pulled up and down, the support seat moves up and down in the mop bucket, and the positioning protrusions of the support seat alternately stay on the low limit portion and the high limit portion.

[0013] The track is provided with an inlet, and the positioning protrusion enters the track from the inlet of the track, and the inlet of the track is covered by the pressure cover at the upper end of the mop bucket; and at least two pairs of tracks are provided on both sides of the mop bucket.

[0014] A guide rod is provided at the lower end of the mop bucket, and a guide seat is provided at the lower end of the support seat that matches the guide rod. The guide rod is always located in the guide seat. Under the action of the guide seat, the guide rod will not pass through the support seat during the movement of the support seat.

[0015] When the supporting base is located at a low position, the guide base abuts against the lower end of the mop bucket and supports the supporting base.

[0016] A limit plate is fixedly provided on the support base, and the mop head body is placed in the limit plate; or, a plurality of limit convex points are provided on the support base, and the plurality of limit convex points limit the rotation of the mop head body above the support base.

[0017] The lower end of the articulated seat is provided with a slot, the end of the positioning seat is inserted into the slot, and a buckle is provided on the slot, and the positioning seat is provided with a slot that matches the buckle; or, the lower end of the articulated seat is provided with a slot, the end of the positioning seat is provided with an insertion rod, the insertion rod extends into the slot, and a buckle is provided on the slot, and the positioning seat / insertion rod is provided with a slot that matches the buckle; or, the upper end of the positioning seat is provided with a slot, the lower end of the articulated seat is provided with an insertion rod inserted into the slot, and a buckle is provided on the side of the articulated seat / the insertion rod is provided with a buckle, and the positioning seat is provided with a slot that matches the buckle.

[0018] A through hole is provided in the middle of the mop head body, and a step portion is provided in the through hole. The hinged seat abuts against the step portion, and the through hole is clamped with a limiting cover on the other side of the step portion. Under the action of the limiting cover, the hinged seat cannot be detached from the through hole and is rotatably set in the middle through hole of the mop head body.

[0019] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0020] 1. The positioning seat of the present invention is powered and rotated by the articulated seat. When the positioning seat rotates, the rotating scraper rotates to squeeze the wipes. The user only needs to place the mop head flat on the support seat, ensure that the articulated seat and the positioning seat are plugged in, and then drive the articulated seat to rotate, making the overall operation simple. In addition, the rotating scraper actively squeezes the wipes to clean them. The more the articulated seat rotates, the more the scraper squeezes, and the effect of squeezing the wipes can be effectively controlled by the user. The rotatable scraper placed in the mop bucket can achieve scraping and washing of the wipes, making the scraping and washing structure more simplified.

[0021] 2. The support base of the present invention is equipped with at least two scrapers. The scrapers are linked to each other, so when one scraper is driven and rotated, the others also rotate. The simultaneous rotation of multiple scrapers ensures that the wiped material is cleaned synchronously. Preferably, two adjacent scrapers are staggered. This staggered arrangement prevents interference between adjacent scrapers and ensures that the distance between adjacent scrapers is less than the rotation radius, allowing for comprehensive cleaning of the wiped material.

[0022] 3. The support base of the present invention is movably mounted within the mop bucket. The support base moves within a track via positioning bumps, allowing the support base to remain in either a low or high position within the mop bucket. When the support base is in the low position, the mop head can contact the liquid within the mop bucket, and the scraper rotates to clean the mop. When the support base is in the high position, the mop head does not contact the liquid within the mop bucket, and the scraper rotates to squeeze the mop. This allows for both cleaning and squeezing simply by moving the support base, resulting in a simple structure and excellent results.

[0023] 4. The mop bucket of the present invention is provided with at least two pairs of tracks on both sides. When two pairs of tracks are provided, the support base is supported by four positioning protrusions, which makes the support base more stable when maintained in the low and high positions. Moreover, during the movement of the support base, the four positioning protrusions provide synchronous guidance, making the movement of the support base more stable.

[0024] 5. The mop bucket of the present invention is provided with a guide rod at the lower end, and a guide seat is provided at the lower end of the support base that cooperates with the guide rod. The guide rod is always located within the guide seat. The cooperation between the guide rod and the guide seat ensures more stable movement of the support base. Preferably, the length of the guide seat plus the height of the support base is greater than the travel distance of the support base. This ensures that the guide rod does not protrude from the support base during movement, which would affect the placement of the mop head.

[0025] 6. The mop head of this invention is easy to install. The specific installation method is as follows: First, insert the hinged base into the through-hole in the middle of the mop head body, let the hinged base rest on the step, and then buckle the limit cover. The entire assembly can be completed manually without the use of tools, greatly reducing processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-19 As shown:

[0048] A cleaning tool includes a mop 1 and a mop bucket 2. The mop 1 includes a mop rod 10, a mop head 11 rotatably connected to the mop rod 10, and a wiper 113 disposed on the mop head 11. The mop head 11 can be rotated using methods known in the art, such as those disclosed in Chinese Patent No. CN2010202394946. The mop rod 10 includes at least a first rod 101 and a second rod 102 that are interconnected. The first and second rods 101, 102 are driven by an internal spiral member, converting the telescopic motion between the first and second rods 101, 102 into rotational motion of the first rod 101. The mop head 11 is hinged to the lower end of the first rod 101. Other methods may also be used to rotate the mop head 11, such as manually rotating the mop rod 10 or providing an electric drive device within the mop rod 10 to drive the rotation of the mop rod 10.

[0049] The mop bucket 2 is provided with a support base 3, a positioning base 31 is rotatably provided on the support base 3, and a scraper 30 is integrally formed on the positioning base 31 or the scraper 30 is fixedly provided. The fixing method of the scraper 30 and the positioning base 31 is selected according to the actual production requirements of the manufacturer. Both fixed and integrally formed methods are acceptable. It is only necessary to realize that the rotation of the positioning base 31 can drive the scraper 30 to rotate.

[0050] The mop head 11 includes a mop head body 111, with an articulated seat 112 rotatably provided in the middle of the mop head body 111. The articulated seat 112 is hingedly connected to the lower end of the mop rod 10. Preferably, the lower end of the mop rod is provided with a mop rod hinge 105, and the articulated seat 112 is hingedly connected to the mop rod hinge 105. The lower end of the articulated seat 112 is plugged into the positioning seat 31, and the articulated seat 112 can synchronously drive the positioning seat 31 to rotate through a transmission plug-in method. There are various plug-in methods, such as inserting the articulated seat into a slot at the end of the positioning seat, or inserting the positioning seat into a slot of the articulated seat. Any plug-in method that allows the two to drive each other is acceptable.

[0051] When the mop head 11 is placed on the support base 3, the positioning base 31 is powered by the hinge base 112 and rotates. When the positioning base 31 rotates, the scraper 30 performs a rotational squeezing on the wiping material 113 below the mop head body 111. Figure 1 、 Figure 4 and Figure 5 As shown, the user simply needs to place the mop head flat on the support base 3, ensure that the hinge base 112 and the positioning base 31 are plugged in, and then drive the hinge base 112 to rotate. The overall operation is simple. In addition, the rotating scraper actively squeezes the wipes to clean them. The more the hinge base rotates, the more the scraper squeezes, and the effect of squeezing the wipes can be effectively controlled by the user. The wipes are preferably cleaning cloths / cotton pads.

[0052] At least two scrapers 30 are provided above the support base 3, and the scrapers 30 are linked to each other. When one scraper 30 is driven and rotated, the other scrapers 30 also rotate. By rotating multiple scrapers 30 together, it can be ensured that the wipes 113 are cleaned synchronously. As a preferred embodiment, Figure 6 As shown, two adjacent scrapers 30 are staggered. After the staggered arrangement, interference between adjacent scrapers 30 can be avoided. Moreover, after the staggered arrangement, the distance between adjacent scrapers is less than the rotation radius, so the wiped object can be fully cleaned.

[0053] The support base 3 is equipped with several intermeshing transmission gears 32. The scraper 30 is fixedly mounted on the central rotating shaft of the transmission gear 32 or is integrally formed with the scraper 30. The meshing of the mechanical gears achieves synchronized rotation of the scrapers 30, ensuring structural stability. Preferably, the central portion of the transmission gear is limited by a rotating shaft 39, which can be a separate component or a protruding column integrally formed within the support.

[0054] The support base 3 is movably disposed within the mop bucket 2. A lower limit portion 43 and a higher limit portion 42 are provided on the sidewall of the mop bucket 2. A positioning protrusion 51 is provided on the support base 3. The positioning protrusion 51 can be retained on the lower limit portion 43 or the higher limit portion 42. When the positioning protrusion 51 is located on the lower limit portion 43, the support base 3 is located at the lower position of the mop bucket 2; when the positioning protrusion 51 is located on the higher limit portion 42, the support base 3 is located at the higher position of the mop bucket 2. The support base 3 moves within the track 41 via the positioning protrusion 51, thereby maintaining the support base 3 at the lower and higher positions of the mop bucket 2. When the support base 3 is in the lower position, the mop head 11 can contact the liquid in the mop bucket 2, and the scraper 30 rotates to clean the wipes 113. When the support base 3 is in the higher position, the mop head 11 does not contact the liquid in the mop bucket 2, and the scraper 30 rotates to squeeze the wipes 113. Cleaning and squeezing can be achieved by moving the support base 3, with a simple structure and good effect.

[0055] The mop bucket 2 is provided with a pair of track seats 4 on either side. Track seats 4 are provided with tracks 41, and positioning bumps 51 move within the tracks 41. The tracks 41 are provided with lower and upper limit portions 43 and 42. Furthermore, the hinged seat 112 of the mop head 11 is locked with the positioning seat 31. By pulling the mop up and down, the support seat 3 moves up and down within the mop bucket 2, and the positioning bumps 51 of the support seat 3 alternately rest on the lower and upper limit portions 43 and 42. To remove the mop head 11 from the positioning seat 31, the user simply applies force to disengage the mop head 11.

[0056] The support base 3 is shown with a track bracket 5 fixed below it. The track bracket 5 is provided with the aforementioned positioning bumps 51 at both ends. The track 41 is provided with an inlet 44, through which the positioning bumps 51 enter the track 41. Furthermore, the inlet 44 of the track 41 is covered by the gland 20 at the upper end of the mop bucket 2. During assembly, the positioning bumps 51 of the support base 3 are first aligned with the inlet 44 of the track 41 and inserted smoothly. The gland 20 is then placed on the support base 3 to complete the assembly of the track 41. The gland 20 prevents the positioning bumps 51 from detaching, facilitating installation and maintaining the overall structure's stability.

[0057] At least two pairs of rails 41 are provided on both sides of the mop bucket 2. When two pairs of rails 41 are provided, the support base 3 is supported by four positioning protrusions 51. Then, the support base 3 is more stable when maintained in the low position and the high position. Moreover, during the movement of the support base 3, the four positioning protrusions 51 provide synchronous guidance, and the movement of the support base 3 will also be more stable.

[0058] The mop bucket 2 is provided with a guide rod 21 at the lower end, and the support base 3 is provided with a guide seat 38 at the lower end that cooperates with the guide rod 21. The guide rod 21 is always located within the guide seat 38. The cooperation between the guide rod 21 and the guide seat 38 ensures more stable movement of the support base 3. Preferably, the length of the guide seat 38 plus the height of the support base 3 is greater than the travel distance of the support base 3. In this way, the guide rod 21 will not pass through the support base 3 during movement of the support base 3. If the guide rod 21 passes through the support base 3, it will affect the placement of the mop head 11.

[0059] When the support seat 3 is in a low position, the guide seat 38 rests against the lower end of the mop bucket 2 and supports the support seat 3. When washing the mop at a low position, due to the resistance of water, the force applied by the user to press down on the mop will increase. Therefore, the guide seat 38 is used to assist the support seat 3 to ensure the stability of the structure.

[0060] like Figure 8 As shown, the support base 3 is fixedly provided with a limit plate 37, and the mop head body 111 is placed within the limit plate 37, which limits the rotation of the mop head body 111. Alternatively, the support base 3 is provided with a plurality of limit bumps, which limit the rotation of the mop head body 111 above the support base 3. The limit bumps can be distributed around the mop head body or inserted into the wiping material / mop head body, and the limit bumps limit the rotation of the mop head body 111. Both solutions are acceptable, and manufacturers can choose the method of limiting the position of the mop head body 111. If the mop head body 111 is not limited, the rotating scraper 30 will drive the mop head body 111, and the mop head body 111 will hit the side wall of the mop bucket 2, affecting the user experience. Therefore, the limit plate 37 / limit bumps are used to limit the position of the mop head body 111, making the wiping material 113 more stable during the scraping and washing process.

[0061] The mop head body 111 has a through hole in the middle, with a step 1111 in the through hole. The hinged seat 112 rests against the step 1111, and a limit cap 114 is clamped on the other side of the through hole. The limit cap 114 prevents the hinged seat 112 from detaching from the through hole and allowing it to rotate within the through hole in the middle of the mop head body 111. The mop head of this application is easy to install. The specific installation method is as follows: first, insert the hinged seat 112 into the through hole in the middle of the mop head body 111, allowing the hinged seat 112 to rest against the step 1111, and then buckle the limit cap 114. The entire assembly can be completed manually without the use of tools, significantly reducing processing costs.

[0062] The articulated seat 112 needs to drive the positioning seat 31 to rotate and move the positioning seat 31 up and down. Therefore, there needs to be two parts of plugging and clamping between the articulated seat 12 and the positioning seat 31. The structures used between the two are diverse. Some of the possible implementation methods are described; Method 1: For example Figure 10 and Figure 11 As shown, the lower end of the articulated seat 112 is provided with an articulated seat slot 1121, the end of the positioning seat 31 is inserted into the articulated seat slot 1121, and the slot 312 is composed of a plurality of articulated seat buckles 1122, and the positioning seat 31 is provided with a positioning seat slot 311 that cooperates with the articulated seat buckle 1122; Mode 2: The lower end of the articulated seat 112 is provided with an articulated seat slot 1121, the end of the positioning seat 31 is provided with a positioning seat plug rod, the positioning seat plug rod extends into the articulated seat slot 1121, and the articulated seat slot 1121 is provided with an articulated seat buckle 1122, and the positioning seat / plug rod is provided with a slot that cooperates with the articulated seat buckle 1122; Mode 3: As shown Figure 12 and Figure 13 As shown, the upper end of the positioning seat 31 is provided with a positioning seat slot 312, the lower end of the hinge seat 112 is provided with a hinge seat plug rod 1123 inserted into the positioning seat slot 312, and the hinge seat plug rod 1123 is provided with a hinge seat buckle 1122, and the positioning seat 31 is provided with a positioning seat slot 311 that cooperates with the hinge seat buckle 1122; Mode 4: As shown Figure 14 and Figure 15 As shown and Figure 18 and Figure 19As shown, the upper end of the positioning seat 31 is provided with a positioning seat slot 312, and the lower end of the hinge seat 112 is provided with a hinge seat plug rod 1123 inserted into the positioning seat slot 312. The hinge seat plug rod 1123 can be square or polygonal, as long as the positioning seat 31 can be driven to rotate by the hinge seat plug rod 1123. In addition, the side of the hinge seat 112 is provided with a hinge seat buckle 1122, and the positioning seat 31 is provided with a positioning seat slot 311 that cooperates with the hinge seat buckle 1122; Method 5: As shown in FIG. Figure 16 and Figure 17 As shown, a positioning seat slot 312 is provided at the upper end of the positioning seat 31, and a hinge seat plug rod 1123 is provided at the lower end of the hinge seat 112 to be inserted into the positioning seat slot 312, and at least two hinge seat plug rods 1123 are provided, and a hinge seat buckle 1122 is provided on the side of the hinge seat 112, and the positioning seat 31 is provided with a positioning seat slot 311 that cooperates with the hinge seat buckle 1122.

[0063] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
