Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of household appliances, and particularly relates to a mop. BACKGROUND

[0002] A mop, also known as a floor mop, refers to a long-handled cleaning tool for scrubbing the floor, and also refers to a long-handled cleaning tool in general. The mop is provided with a mop cloth, which needs to be wrung out after scrubbing the floor with water stains or after being cleaned. One end of the mop cloth of the mop can be fixedly connected with the mop rod, and the other end of the mop cloth can be connected with a movable piece arranged on the mop rod, so that the distance between the two ends of the mop cloth can be adjusted, so that the mop cloth can have different shapes. For example, a mop disclosed in a prior application of the present applicant, Chinese Patent ZL202223208335.1, which keeps the sleeve at a specific position on the mop rod through a limiting mechanism.

[0003] However, in the above-mentioned manner, when the user rotates the sleeve to wring out the wiping material, the wiping material becomes shorter in the length direction of the mop rod as the sleeve rotates, so that the sleeve gradually moves downward until the second limiting part passes the first limiting part. However, in this way, the first limiting part and the sleeve are simultaneously provided with a rotation-stopping structure, and the rotation-stopping structure needs to have a certain length in the axial direction of the mop rod to ensure its structural reliability. Therefore, when the second limiting part presses on the first limiting part, the rotation-stopping structure will lose its function, so that the sleeve will rotate back under the driving of the wiping material, thereby making it inconvenient to wring out the wiping material. The size of the disabled interval is related to the length of the first limiting part.

[0004] Therefore, there is an urgent need for a new limiting way of the sleeve and the mop rod in the axial direction of the mop rod to reduce the disabled interval of the rotation-stopping structure. CONTENT OF THE UTILITY MODEL

[0005] The present application aims to solve the problem of the rotation-stopping structure losing its function in the prior art, so that the sleeve rotates back under the driving of the wiping material, thereby making it inconvenient to wring out the wiping material.

[0009] The mop rod further comprises a first limiting part arranged below the rotation-stopping tooth and a second limiting part arranged inside the sleeve, the first limiting part and the second limiting part are connected by clamping to limit the movement of the sleeve and the mop rod in the axial direction of the mop rod.

[0010] In some embodiments, the length of the rotation-stopping tooth is greater than the length of the second limiting part along the length direction of the mop rod.

[0011] In some embodiments, the first limiting part is arranged on the mop rod and can be elastically retracted inside the mop rod, and the second limiting part is arranged on the inner wall of the sleeve to clamp the first limiting part.

[0012] In some embodiments, the second limiting part is shaped as an annular protruding rib on the inner wall of the sleeve.

[0013] In some embodiments, a guide slope towards the sleeve is arranged on the first limiting part in the axial direction of the mop rod, and a matching slope towards the mop rod is arranged on the second limiting part.

[0014] In some embodiments, a driving device is further arranged to drive the clamping of the first limiting part and the second limiting part to be released.

[0015] In some embodiments, the driving device comprises a main body part and a pressing part arranged at the first end of the main body part, and the first limiting part is connected to the second end of the main body part.

[0016] In some embodiments, the driving device is rotationally connected to the mop rod, and the driving device further comprises a torsion device to make the pressing part and the first limiting part respectively protrude out of the outer side of the mop rod in opposite directions.

[0035] The present application will be described below in conjunction with the accompanying drawings and specific embodiments:

[0036] As Figures 1-5 The present application discloses a mop, which comprises a mop rod 1 and a sleeve 2, and two ends of a wiping material are connected to the mop rod 1 and the sleeve 2 respectively.

[0037] The mop rod 1 is generally in the shape of a long rod, and the material can be solid plastic or metal to ensure sufficient strength and durability. The cross section of the rod should be at least partially circular to allow the sleeve 2 to rotate smoothly on the mop rod 1. The upper end of the mop rod 1 is generally held by the user during cleaning operation, and a handle, a hanging ring or other components can be installed thereon. The lower end of the mop rod 1 is used to connect with one end of the wiping material, which can directly fix the wiping material at the lower end of the mop rod 1, or install the wiping material at the lower end of the mop rod 1 through a detachable mounting seat.

[0038] The sleeve 2 of the present application is generally cylindrical, or it should at least have a cylindrical inner cavity, so that it can be sleeved on the mop rod 1, and through appropriate fitting tolerance, the inner diameter of the sleeve is slightly larger than the outer diameter of the mop rod, so that it can freely slide and rotate on the mop rod. The other end of the wiping material is connected to the sleeve 2, for example through common fixing methods such as bolts, buckles or magic tapes, etc., to ensure that the wiping material can be firmly fixed on the sleeve, when the sleeve 2 rotates on the mop rod 1, the wiping material gradually winds on the mop rod 1, as the user gradually applies force to the sleeve 2, the wiping material is gradually "pulled" tight and wound on the mop rod 1, so that the cleaning liquid in the wiping material is squeezed out.

[0039] The mop of the present application also includes a rotation stopping structure, including one-way teeth 21 and rotation stopping teeth 11, wherein the one-way teeth 21 are arranged on the inner side of the sleeve 2, they are arranged along the circumferential direction of the sleeve, have a specific tooth shape and angle to realize the function of one-way rotation stopping, for example, the one-way teeth have a spacing of 3 mm and are arranged in 15 numbers, and the rotation stopping teeth 11 are arranged on the outer side of the mop rod 1 and cooperate with the one-way teeth, in order to ensure its reliability, the rotation stopping teeth should have a certain length, for example, the length is 10 mm.

[0040] The mop of the present application also includes a first limiting part 12 and a second limiting part 22, the first limiting part 12 is located below the rotation stopping teeth 11, and the second limiting part 22 is located on the inner side of the sleeve 2, when the sleeve 2 is sleeved on the mop rod 1, the first limiting part 12 and the second limiting part 22 cooperate with each other through clamping, thereby limiting the movement of the sleeve 2 and the mop rod 1 in the axial direction of the mop rod 1, and in the axial direction of the mop rod 1, the length of the first limiting part 12 should be less than the length of the rotation stopping teeth 11 in this direction, for example, the length of the first limiting part 12 is 3 mm. Wherein, when the rotation stopping teeth 11 protrude from the side surface of the mop rod 1, the first limiting part 12 is generally also protruding from the side surface of the mop rod 1, which can be protruding from the side surface of the mop rod 1 in an extendable and retractable manner, or can be fixedly protruding from the side surface of the mop rod 1.

[0041] In some embodiments, the first limiting part 12 of the present application is protruded on the mop rod 1 and can be elastically retracted into the mop rod 1, and the second limiting part 22 is protruded on the inner wall of the sleeve 2. When it is needed to fix the sleeve 2 to the mop rod 1, the first limiting part 12 can be retracted into the mop rod 1, so that the second limiting part 22 can smoothly pass the position of the first limiting part 12. When the sleeve 2 moves to the predetermined position, the first limiting part 12 is protruded on the side of the mop rod 1. At this time, when the sleeve 2 has a tendency to slide to the lower end of the mop rod 1 under the action of gravity or other external force, the second limiting part 22 can be clamped with the first limiting part 12, so as to limit the relative movement of the sleeve 2 and the mop rod 1 along the axis of the mop rod 1. When it is needed to move the sleeve 2 to the lower end of the mop rod 1, the first limiting part 12 can also be retracted into the mop rod 1, so that the second limiting part 22 can smoothly pass the position of the first limiting part 12, so as to move the sleeve 2 to the lower end of the mop rod 1. In addition, it should be noted that when the first limiting part 12 is protruded on the mop rod 1 and cannot be elastically retracted into the mop rod 1, the first limiting part 12 or the second limiting part 22 should have a certain deformation ability, and the material is usually selected from rubber or plastic materials with good elasticity. These materials have a certain elastic deformation ability and can maintain good elastic recovery performance during multiple uses and disassembly, thereby providing reliable protection for the normal use of the mop and achieving the above technical effects.

[0042] Specifically, in the present application, the second limiting part is arranged in the form of an annular protruding rib, so that no matter what angle the sleeve 2 is rotated to on the mop rod 1, the first limiting part 12 can be clamped with the second limiting part 22, thereby avoiding the clamping failure caused by the change of the length of the wiping material.

[0043] Further, along the axis of the mop rod 1, the mop of the present application is further provided with a guide slope 121 on the first limiting part 11 and a matching slope 221 on the second limiting part 22. The guide slope 121 is directed towards the sleeve 2, i.e. towards the second limiting part 22, and the matching slope 221 is directed towards the mop rod 1, i.e. towards the first limiting part 12. When it is needed to fix the sleeve 2 to the mop rod 1 by clamping the first limiting part 12 and the second limiting part 22, due to the existence of the guide slope 121, the matching slope 221 on the inner side of the sleeve 2 will be in contact with the guide slope 121 during the movement of the sleeve 2 on the mop rod 1. With the continuous movement of the sleeve 2, the matching slope 221 gradually slides along the guide slope 121 and gradually presses the first limiting part 12 into the mop rod 1, so that the first limiting part 12 is retracted into the mop rod 1, thereby enabling the sleeve 2 to smoothly pass the position of the first limiting part 12 to complete the upward movement. The design of the slope makes the upward movement of the sleeve 2 more smooth and natural, and reduces the resistance and jamming phenomenon in the upward movement.

[0044] In some embodiments, the mop of the present application further comprises a driving device 3, which can be in various forms, such as electric driving mode, mechanical driving mode or pneumatic driving mode, etc. When it is necessary to release the clamping of the first limiting part 12 and the second limiting part 22, the driving device 3 starts to work. If it is electric driving mode, it can drive the corresponding transmission mechanism, such as lead screw, gear, etc., by motor to transmit power to the first limiting part 12, so that it overcomes the elastic force or other fixing force to retract, thereby releasing the clamping with the second limiting part 22, while the mechanical driving mode can achieve the operation of the first limiting part 12 through some connecting rods, levers, cams, etc. to achieve the purpose of releasing the clamping, and the pneumatic driving mode drives the related parts by using the pressure of compressed air to make the first limiting part 12 act. The setting of the driving device 3 makes the user more convenient and efficient to release the clamping of the first limiting part 12 and the second limiting part 22 when it is necessary to disassemble or adjust the parts of the mop, without the need for manual labor operation, improving the efficiency and convenience of operation. For example, when it is necessary to move the sleeve 2 to the lower end of the mop rod 1 to make the wiping material dispersed in a larger area for cleaning operation, only the driving device 3 needs to be started to complete the action of releasing the clamping, and then the user can easily move the sleeve 2 to the lower end of the mop rod 1, or even under the action of the gravity of the sleeve 2, the sleeve 2 can slide to the lower end of the mop rod 1. Moreover, the driving device 3 can be connected with the control system of the mop, and its start and stop can be controlled by some buttons, switches or remote controllers, etc., further increasing the convenience and flexibility of operation.

[0045] Further, the driving device 3 of the present application is in mechanical driving mode, which comprises a main body part 31 and a pressing part 32, the main body part 31 is usually made of solid material, such as metal or high-strength plastic, to ensure its reliability and durability during long-term use. The pressing part 32 is arranged at the first end of the main body part 31, which is convenient for user to press, only needs to press the pressing part 32 with fingers or other appropriate tools to trigger the work of the driving device 3, and its shape and size can be designed according to the user's use habit to provide comfortable operation feeling. The first limiting part 12 is connected to the second end of the main body part 31, and when the pressing part 32 is pressed, the force will be transmitted to the first limiting part 12 through the transmission of the main body part 31. The first limiting part 12 can be connected to the main body part 31 in elastic connection or other mechanical connection, etc. to ensure that it can smoothly act when pressed. In addition, in order to ensure the stability and reliability of the driving device 3, some auxiliary structures or parts, such as guiding mechanism, limiting device, etc. can be arranged between the main body part 31 and the first limiting part 12 to ensure the accurate and stable movement track of the first limiting part 12, avoiding the problems of jamming or deviation, etc.

[0046] Further, the driving device 3 is rotatably connected with the mop rod 1, and the driving device 3 further comprises a torsion device 33, which is usually composed of elastic material or torsion spring, etc., and can generate a certain torsion force, so that the pressing part 32 and the first limiting part 12 can be kept in a specific position state when no external force is applied, and when the pressing part 32 is pressed, the first limiting part 12 is withdrawn into the mop rod 1, and the torsion device 33 is charged, and when the pressing part 32 is released, the torsion device 33 can drive the first limiting part 12 and the pressing part 32 to reset, and the pressing part 32 and the first limiting part 12 can always keep in a state of protruding in opposite directions outside the mop rod 1 without external force.

[0047] In some embodiments, the rotating tooth 11 and the first limiting part 12 are designed as a whole, which simplifies the production process, reduces the number of parts and assembly procedures, improves the production efficiency, and reduces the production cost.

[0048] Specifically, the rotating tooth 11 and the first limiting part 12 are arranged on the mop rod 1 through the elastic cantilever, and both are located at the free end of the elastic cantilever, so that the rotating tooth 11 and the first limiting part 12 can protrude from the side of the mop rod 1 without external force through the structure of the elastic cantilever, and the elastic cantilever has a certain elastic deformation capacity, so that the rotating tooth 11 and the first limiting part 12 can be withdrawn into the mop rod 1 when the mop rod 1 is subjected to external force, that is, the wiping material can restore to the loose state without external force when the wiping material is twisted to the desired degree of water being squeezed out, so as to perform the cleaning operation.

[0049] In some embodiments, the mop of the present application comprises a driving device 3, which comprises a main body part 31 and a pressing part 32, and the combination of the pressing part 32, the rotating tooth 11 and the first limiting part 12 are distributed at both ends of the main body part 31, so that when the user needs to fix the sleeve 2 at a specific position on the mop rod 1 through the clamping of the first limiting part 12 and the second limiting part 22 or needs to contact and clamp from the position, only the pressing part 32 needs to be pressed, so that the first limiting part 12 is withdrawn into the mop rod 1, so that the second limiting part 22 is positioned by the first limiting part 12; and when the wiping material is twisted to the desired degree of water being squeezed out through the rotation of the sleeve 2, and then the loose state of the wiping material is restored, the pressing part 11 can also be pressed to withdraw the rotating tooth 11 into the mop rod 1, so that the sleeve 2 can be reversed, so as to restore the state of the wiping material. The withdrawal of the first limiting part 12 and the rotating tooth 11 can be actively withdrawn by pressing the pressing part 32, so as to improve the controllability of the operation.
