[Prior Art] Press, mop is commonly used as one of the cleaning tools for the ground, while the traditional dewatering bucket is used to assist the mop to remove excess water; the traditional dewatering bucket is used to squeeze the cotton strip on the mop. , the water on the cotton strip is drained; the first figure shows a conventional dewatering bucket (10) having a casing (11), a device portion (12), and a rotating unit (13), wherein The rotating unit (13) is driven by a pedal (131), which in turn drives the dewatering basket (μ) to rotate, thereby dehydrating the mop (16); however, the dewatering bucket (1〇) is installed in a manner Essentially missing; it only provides a mop (16) with a vertical space (15). This type of patent is found in US2010/0218335A1, 2010/0242205A1 and 2010/0287724A1 and the like. In fact, the 'dirty mop (16) can't achieve the cleaning effect if it is only moved in this longitudinal direction (γ_γ); the dirt attached to the mop cotton strip (161) cannot be used alone. The way to get rid of the mop cotton strip is that the effect of cleaning the mop cotton strip with a dewatering bucket is limited. At the same time, the dirt originally deposited on the bottom of the dewatering bucket is also easily attached to the cotton strip due to the repeated contact of the cotton strip, which in turn causes the mop to be more dirty than before. Furthermore, the driving mechanism of the conventional dewatering bucket is too complicated, and the user must stand on one foot and use the foot to step on the pedal (131). Therefore, it is not smooth; it is easy to cause the user's center of gravity to be unstable, resulting in falls and the like; Therefore, there is still room for improvement. M415686 [New content] The main purpose of this creation is to provide a double-rotating dewatering bucket. With the same dewatering bucket, the dirt attached to the mop head can be reached, firstly stirred and cleaned, and then the dewatering basket is used. Drain the water to achieve an enhanced effect. Another object of the present invention is to provide a double-rotating dewatering bucket, which does not require pedaling on both rotating members, and is convenient to operate and user-friendly and safe to use. In order to achieve the above purposes, the technical means adopted in this creation is to use a first type of rotation to agitate the cotton strip of a mop, and the second type of rotation can drain the moisture of the cotton strip, including : a barrel body having an open top surface, the bottom edge facing the barrel body to form a higher first protrusion, and a lower second protrusion, and the barrel corresponding to the second protrusion part The barrel wall is formed as a non-smooth concave and convex surface; a first support shaft is fixed to the first protrusion, and the upper portion protrudes from the top surface thereof; and a second support shaft is fixed to the second protrusion a seat, and the upper portion protrudes from the top surface of the φ; a dewatering basket having a first shaft seat with a downward opening at the center of the bottom edge, which can be sleeved on the first support shaft to make the dewatering basket a freely rotating state; and a bearing body having a second shaft seat with a downward opening at the center of the bottom edge, which can be sleeved on the second support shaft to enable the bearing body to be freely rotatable, and a receiving seat is arranged on the top surface of the rotating body, so as to provide a bottom edge of the bottom of the mop Rotated by. M415686, the mop structure comprises: an inner rod body, which is hollow; an outer rod body, also hollow, is sleeved at its bottom end and the upper end of the inner rod body, and is relatively linear a telescopic displacement; a snap member is disposed in the top opening of the inner rod body, and has a perforation on the bottom surface thereof and a driven ratchet on the inner bottom edge; a driving member is arranged in a long spiral shape The outer rod body is synchronously moved up and down with the outer rod body; a brake member is disposed in the engaging member, and a screw sleeve is disposed on the top surface thereof for receiving the driving member, and the bottom end is opposite to the engaging member The driven ratchet is provided with an active ratchet so that the engaging member can only be driven in one direction when being driven by the driving member; a fixing sleeve having a through hole for the driving member to extend and the system The sleeve is disposed on the opening of the engaging member; a locking structure is disposed on the outer rod body for controlling the inner and outer rod bodies to be positioned or in a relatively telescopic state; a disc body is disposed therein The bottom of the rod body is provided with a cotton strip on the periphery thereof, and is disposed at the center of the bottom edge of the disc body, and is disposed across the dewatering barrel Receiving the socket body on the seat, when the disk body is driven by the inner rod body, 360° rotation can be performed on the bearing body, thereby driving the cotton cloth strip to the concave and convex surface of the barrel wall, according to Stir to remove dirt from the cotton strip. [Embodiment] First, referring to the second to eighth figures, the double rotary dewatering bucket (40) of the preferred embodiment of the present invention comprises: a barrel body (20) having an open top surface and a bottom edge facing the barrel The inner body (20) is raised to form a higher first protrusion (21), and a lower second protrusion (22), M415686 and the barrel (20) corresponds to the second protrusion (a) A part of the barrel wall is provided as a non-smooth concave-convex surface (23); in this embodiment, the uneven surface (23) is formed in a wave shape. The first support shaft (24) is fixed to the first protrusion (21), and the upper portion protrudes from the top surface thereof; a second support shaft (25) is fixed to the second protrusion (22) And the upper section is convexly protruded from the top surface thereof; the dehydration monitor (30) has a first shaft seat (31) with a downward opening at the center of the bottom edge, and can be sleeved on the first support shaft (24), The dewatering basket (3〇) is freely rotatable; and a bearing body (60) having a second shaft seat (61) with a downward opening at the center of the bottom edge of the second support shaft The upper body makes the bearing body (6〇) freely rotatable, and the top surface of the bearing body (6〇) is provided with a receiving seat (62) 'to provide a mop (5〇) bottom plate body (56) The center can be rotated synchronously. In this embodiment, the receiving seat (62) of the bearing body (6〇) is formed into a convex non-circular body such as a polygonal & body shape, and the bottom plate of the mop (5〇) The body (56) is matched with the receiving seat (62), and is provided with a sleeve body (58) which is synchronously rotated across the receiving seat (62) and has a corresponding concave polygonal cap (581) shape. . By means of the above-mentioned structure, the bearing body (6〇) can freely rotate on the top surface of the second boss (21) with the second support shaft (Μ) as its axis, and its function is to take over by its top surface. Seat (62) is used to place and position the handle (5〇). Therefore, when the user wants to remove the dirt of the cotton strip (561) of the mop (50), the disc body (56) is first placed in the barrel body (20) and located above the bearing body (6〇). The sleeve body (58) at the center of the bottom edge of the disk body (56) is placed on the socket (62) with its cap (581), so that the mop (50) can be positioned to be displayed in the barrel body ( 20) The type of free rotation within. Therefore, when the user operates the mop (50) to rotate, the cotton strip (561) of the mop (50) is opened by centrifugal force and thrown toward the undulating concave surface (23), which is like a laundry. The function of the board makes the rotating cotton strip (561) appear agitated, so that the barrel (20) acts like a washing machine, effectively removing the dust or dirt adhered thereto. In addition to the cleaning function of the creation, it is not necessary to use a power source such as a motor in the barrel (20), which is a rotary power generated by the mop (50) to achieve self-cleaning effect. Next, as shown in the ninth figure, the tray (56) of the mop (50) with the removed dirt but with moisture is placed in the dewatering basket (30), and the mop (50) is operated to make the tray (56) Rotating and synchronously driving the dewatering basket (30) to rotate, and further removing the moisture of the cotton strip (561) attached to the disc body (56) by centrifugal force, and scooping out the dewatering hole (32). Therefore, the double-transfer dewatering bucket (40) of this creation is like a washing machine and a dehydrator, achieving a dual-function cleaning effect. The mop (50) is uncovered, although a mop generally having a cotton strip can be used, and then the grip is turned by hand to clean or dehydrate. However, the dual rotary dewatering bucket (40) of the present invention is further combined with more than one lower linear displacement to convert into a one-way driven mop (50), which makes the operation labor-saving and convenient, and a preferred embodiment thereof is tenth to fifteenth. The figure includes: an inner rod body (51) consisting of a hollow round rod, which may be made of metal or non-metal, such as an aluminum tube or a plastic tube body. An outer rod body (52) is sleeved with the bottom end and the upper end of the inner rod body (51), and is telescopically displaceable relative to the line. In this embodiment, when the user is a user, the brake member (54) is driven to rotate counterclockwise, and the downward active ratchet (542) of the brake member (54) is upwardly opposed to the engaging member (53). The movable ratchet (535) is an unspinned idling, that is, the engaging member (53) is not moved, so that the driving member (55) is restored to the original position, and the pressing member is again depressed to drive the engaging member (53). ). ° A disc body (56) is disposed at the bottom end of the inner rod body (51) and is provided with a cotton strip (561); a locking structure (57) is attached to the outer rod body (52) for controlling The inner and outer rods (51) and (52) are positioned or relatively telescopic. In the present embodiment, the locking structure (57) is composed of an inner sleeve (57a), an outer cylinder (57b) and a u-shaped wrench (57c), but is not limited thereto. That is, the locking structure (57) can also use the inner sleeve (57a) and the outer clamp (57b) to rotate and lock the inner and outer rods (51), (52) to be positioned or opposite. The state of the expansion. Thus, in the present embodiment, when the u-shaped wrench (57c) is pressed downward, the inner rod body (51) and the outer rod body (52) are unlocked and retractable. When the lip-shaped wrench (57c) is pulled up, the outer cylinder (57b) is lowered, forcing the inner sleeve (57a) to be locked, so that the inner and outer rods (51), (52) are relatively positioned. Therefore, as shown in Fig. 14, when the locking structure (57) is opened and the outer body (52) is pressed downward, the driving member (55) is driven to descend and the screw of the braking member (54) is extended. The sleeve (541) structure rotates the brake member (54) clockwise, and synchronously drives the engaging member (53) to rotate, and the engaging member (53) is fastened to the domain body (51), so that the inner rod body (51) being unidirectionally driven, and as shown in Fig. 15, when the outer rod (52) is pulled up, as described above, when the brake member (54) is rotated counterclockwise, relative to the engaging member ( 53) The system is idling, because the inner rod (51) of the M415686 is still affected by the pull-up of the inertial force rod (52).疋 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Humanization and usability are enhanced.
