Description

Technical Field

[0001] The utility model relates to the technical field of household cleaning daily necessities, in particular to a cleaning structure. Background Art

[0002] In the prior art, there are cleaning structures with collodion heads, such as mops and glass cleaners. Figure 1 As shown, the cleaning structure of the related art is usually provided with a clamping seat 3 at the lower end of the handle 5, and the clamping seat 3 can be clamped with the holding rod 1. The holding rod 1 is provided with a movable sleeve 2, and one end of the pull rod 4 is hinged on the handle 5 and the other end is connected to the collodion head 6. When the clamping seat 3 is clamped with the holding rod 1, the movable sleeve 2 moves toward the direction close to the collodion head 6, driving the pull rod 4 to bend the center of the collodion head 6 toward the direction away from the holding rod 1, so that the collodion head 6 can be automatically disassembled.

[0003] When the sponge head 6 needs to be cleaned, the user pulls the handle 5 upward, and the handle 5 drives the pull rod 4 to move axially along the gripping rod 1, and the pull rod 4 drives the center of the sponge head 6 upward to fold the entire sponge head 6, thereby cleaning the sponge head 6. However, after the user has finished cleaning and squeezing the sponge head 6, the user often fails to reset the clamping seat 3 to the position of clamping with the gripping rod 1 due to negligence. At this time, if the movable sleeve 2 directly moves in the direction close to the sponge head 6, the clamping seat 3 will move away from the gripping rod 1, that is, the entire handle 5 rotates upward, and cannot drive the pull rod 4 to move and remove the sponge head 6, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the utility model provides a cleaning structure to solve the problem that in the cleaning structure with a collodion head in the prior art, the user fails to reset the card seat after squeezing the water, which will affect the automatic disassembly of the collodion head.

[0005] The utility model provides a cleaning structure, comprising:

[0006] Cotton head assembly;

[0007] Hold the pole;

[0008] A movable sleeve, which is movably sleeved on the holding rod and can move along the axial direction of the holding rod;

[0009] The water squeezing mechanism includes an articulated seat, a pull rod and a handle; the handle is hinged to the movable sleeve; the articulated seat is arranged on the handle; the first end of the pull rod is hinged to an end of the articulated seat away from the handle, and the second end of the pull rod is connected to the cotton head assembly;

[0010] The water squeezing mechanism has an initial state; when the water squeezing mechanism is in the initial state, the articulated seat is sleeved outside the holding rod; when the articulated seat is subjected to a driving force, the articulated seat is separated from the holding rod to drive the pull rod to move, thereby driving the cotton head assembly into the water squeezing state; when the driving force is cancelled, the pull rod can drive the water squeezing mechanism to reset to the initial state.

[0011] Beneficial effect: when the user has finished cleaning and squeezing out the water from the cotton head assembly and cancels the driving force on the handle and the hinged seat, the pull rod will drive the squeezing mechanism to automatically reset to its initial state under the action of its own elastic restoring force. Since the pull rod is hinged at the end of the hinged seat away from the handle, the pull rod will not generate an upward component force on the handle during the resetting process, thereby effectively avoiding the phenomenon that the entire handle and the hinged seat are tilted away from the holding rod, causing the pull rod to be unable to move normally and the cotton head assembly to be unable to be automatically disassembled. The user experience is improved, and the problem of the existing cleaning structure with a rubber cotton head is effectively solved. After squeezing out the water, the user often neglects to reset the card seat due to negligence, which affects the automatic disassembly of the rubber cotton head.

[0012] In an optional embodiment, the pull rod is a straight rod structure, and the extension direction of the pull rod is parallel to the extension direction of the gripping rod.

[0013] Beneficial effect: The pull rod adopts a straight rod structure, and the extension direction of the pull rod is parallel to the extension direction of the holding rod. When the user cleans the cotton head assembly by pulling the handle, the end of the pull rod follows the handle to move away from the holding rod, and the pull rod generates elastic deformation at this time. After the user completes the cleaning, the pull rod can reset the handle to its initial state under the action of the elastic restoring force. The hinged seat sleeve is arranged outside the holding rod, and at this time the extension direction of the pull rod is parallel to the axial direction of the holding rod. When the moving sleeve moves in the direction close to the cotton head assembly, the force applied to the pull rod by the moving sleeve is along its extension direction, that is, the pull rod will not be deformed in other directions under the action of the force, but will directly transmit the force to the cotton head assembly, so that the center of the cotton head assembly bends in the direction away from the holding rod, thereby realizing the automatic disassembly of the cotton head assembly.

[0014] In an optional embodiment, in the direction close to the hinge seat, the pull rod includes a straight section and a curved section connected in sequence; the extension direction of the straight section is parallel to the extension direction of the grip rod; the curved section is bent or folded in the direction away from the handle.

[0015] Beneficial effect: the end of one side of the pull rod close to the hinged seat is bent or folded in the direction away from the holding rod, and the end is hinged to the end of the hinged seat away from the handle. After the user finishes cleaning the cotton head assembly, the pull rod resets the handle to its initial state under the action of the elastic restoring force. The hinged seat is arranged outside the holding rod. At this time, the force application point of the handle on the pull rod is located on the lower side of the central axis of the holding rod. When the movable sleeve moves in the direction close to the rubber cotton head, the force applied by the movable sleeve makes the handle continue to move in the direction close to the holding rod, that is, the handle and the hinged seat can always be kept in the initial position, and the pull rod can directly transmit the force applied by the movable sleeve to the cotton head assembly along the axial direction of the holding rod, thereby realizing automatic disassembly of the cotton head assembly.

[0016] In an optional embodiment, the hinge seat includes a hinge plate; the number of the hinge plates is set to two, the two hinge plates are arranged opposite to each other and are respectively arranged on both sides of the handle; there are two pull rods, the first ends of the two pull rods are respectively hinged on the two hinge plates, and the second ends of the two pull rods are respectively connected to the corresponding positions of the cotton head assembly.

[0017] Beneficial effect: By adopting two hinged plates arranged relatively to each other, two pull rods are correspondingly arranged, and the two pull rods and the two hinged plates are distributed on both sides of the holding rod. The two pull rods and the two hinged plates are correspondingly connected to the handle and the cotton head assembly on both sides. This design makes the handle more balanced and stable when driving the cotton head assembly to move.

[0018] In an optional embodiment, a first hinge portion is provided on the hinge plate; a second hinge portion is provided on the pull rod; and the first hinge portion and the second hinge portion are hinged to each other.

[0019] Beneficial effect: The hinged plate and the pull rod are connected by a first hinged portion arranged on the hinged plate and a second hinged portion arranged on the pull rod, and the first hinged portion and the second hinged portion are hinged to each other.

[0020] In an optional embodiment, the first hinged part includes a hinge shaft; the second hinged part includes a hinge ring.

[0021] Beneficial effect: The first hinged part and the second hinged part are connected more conveniently and quickly by adopting the form of a hinge shaft and a hinge ring.

[0022] In an optional embodiment, a slot is provided in the middle of the end of the hinge shaft.

[0023] Beneficial effect: A slot is provided in the middle of the end of the hinge shaft. By providing the slot in the middle of the end of the hinge shaft, when the hinge ring is connected to or disassembled from the hinge shaft, the hinge shaft is squeezed by the hinge ring and is more likely to deform and shrink inward, thereby making it easier to disassemble and assemble the hinge shaft and the hinge ring and improving assembly efficiency.

[0024] In an optional embodiment, a conical guide portion is provided at the end of the hinge shaft.

[0025] Beneficial effect: The end of the hinge shaft is provided with a conical guide portion. The conical guide portion provided at the end of the hinge shaft can play a guiding role, so that the hinge shaft and the hinge ring can be quickly positioned, further improving the assembly efficiency of the hinge shaft and the hinge ring.

[0026] In an optional embodiment, the handle includes a support body and a hinge structure and a pull ring portion arranged at both ends of the support body; the support body includes a straight portion and an arc portion, and the straight portion is connected between the arc portion and the pull ring portion; the handle is hinged to the movable sleeve through the hinge structure;

[0027] The hinge structure is arranged on the end of the arc-shaped portion; and / or the hinge seat is fixedly arranged on the straight portion.

[0028] Beneficial effects: The support body of the handle is convenient for connecting the handle with the movable sleeve by adopting the design of the arc portion, and is convenient for connecting the hinge seat with the handle by adopting the design of the straight portion.

[0029] In an optional embodiment, the cotton head assembly includes a cotton head and a mounting structure; the cotton head is detachably arranged on the mounting structure, and the movable sleeve has a locked state and a released state;

[0030] When the movable sleeve is in a locked state, the cleaning structure can perform cleaning or water squeezing operations;

[0031] When the movable sleeve is in a released state, the movable sleeve moves toward the direction close to the cotton head, and drives the middle part of the pull rod holding the cotton head to bend or bend toward the direction away from the holding rod, so that the cotton head can be automatically disassembled.

[0032] Beneficial effect: The cotton head assembly adopts a mounting structure and a design in which the cotton head is detachably arranged on the mounting structure, which facilitates the installation and fixation of the cotton head on the one hand, and also facilitates the automatic disassembly of the cotton head on the other hand.

[0033] In an alternative embodiment, the cleaning structure comprises a mop or a glass wiper. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0056] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] Combine the following Figures 2 to 9 , describing an embodiment of the utility model.

[0059] According to an embodiment of the utility model, the utility model provides a cleaning structure, including a cotton head assembly 10, a gripping rod 20, a movable sleeve 30, and a water squeezing mechanism 40. The movable sleeve 30 is movably sleeved on the gripping rod 20, and the movable sleeve 30 can move along the axial direction of the gripping rod 20; the water squeezing mechanism 40 includes a hinge seat 41, a pull rod 42, and a handle 43; the handle 43 is hinged to the movable sleeve 30; the hinge seat 41 is arranged on the handle 43; the first end of the pull rod 42 is hinged At the end of the hinged seat 41 away from the handle 43, the second end of the pull rod 42 is connected to the cotton head assembly 10; the water squeezing mechanism 40 has an initial state; when the water squeezing mechanism 40 is in the initial state, the hinged seat 41 is sleeved outside the holding rod 20; when the hinged seat 41 is subjected to a driving force, the hinged seat 41 is separated from the holding rod 20 to drive the pull rod 42 to move, thereby driving the cotton head assembly 10 to enter the water squeezing state; when the driving force is cancelled, the pull rod 42 can drive the water squeezing mechanism 40 to reset to the initial state.

[0060] In the above embodiment, when the user has finished cleaning and squeezing water from the cotton head assembly 10 and cancels the driving force on the handle 43 and the hinged seat 41, the pull rod 42 will drive the squeezing mechanism 40 to automatically reset to the initial state under the action of its own elastic restoring force. Since the pull rod 42 is hinged at the end of the hinged seat 41 away from the handle 43, the pull rod 42 will not generate an upward component force on the handle 43 during the resetting process, thereby effectively avoiding the phenomenon that the entire handle 43 and the hinged seat 41 are tilted away from the holding rod 20, resulting in the pull rod 42 being unable to move normally, making it impossible for the cotton head assembly 10 to be automatically disassembled. The user experience is improved, and the problem of the existing cleaning structure with a rubber cotton head is effectively solved. After squeezing water, the user often fails to reset the card seat due to negligence, which affects the automatic disassembly of the rubber cotton head.

[0061] In some embodiments, Figures 2 to 6 As shown, the pull rod 42 is a straight rod structure, and the extension direction of the pull rod 42 is parallel to the extension direction of the gripping rod 20 .

[0062] In the above embodiment, the pull rod 42 adopts a straight rod structure, and the extension direction of the pull rod 42 is parallel to the extension direction of the gripping rod 20. When the user cleans the cotton head assembly 10 by pulling the handle 43, the end of the pull rod 42 follows the handle 43 to move away from the gripping rod 20, and the pull rod 42 generates elastic deformation. After the user finishes cleaning, the pull rod 42 can restore the handle 43 to the initial state under the action of the elastic restoring force. The hinge seat 41 is sleeved outside the gripping rod 20, and at this time, the extension direction of the pull rod 42 is parallel to the axial direction of the gripping rod 20. When the moving sleeve 30 moves in the direction close to the cotton head assembly 10, the force applied by the moving sleeve 30 to the pull rod 42 is along its extension direction, that is, the pull rod 42 will not be deformed in other directions under the action of the force, but will directly transmit the force to the cotton head assembly 10, so that the center of the cotton head assembly 10 bends in the direction away from the gripping rod 20, thereby realizing the automatic disassembly of the cotton head assembly 10.

[0063] In some embodiments, Figures 7 to 9 As shown, in the direction close to the hinge seat 41, the pull rod 42 includes a straight section 421 and a curved section 422 connected in sequence; the extension direction of the straight section 421 is parallel to the extension direction of the gripping rod 20; the curved section 422 is bent or folded in the direction away from the handle 43.

[0064] In the above embodiment, the end of the pull rod 42 close to the hinge seat 41 is bent or folded in the direction away from the holding rod 20, and the end is hinged to the end of the hinge seat 41 away from the handle 43. After the user finishes cleaning the cotton head assembly 10, the pull rod 42 resets the handle 43 to the initial state under the action of the elastic restoring force. The hinge seat 41 is sleeved on the outside of the holding rod 20. At this time, the force application point of the handle 43 on the pull rod 42 is located on the lower side of the central axis of the holding rod 20. When the movable sleeve 30 moves in the direction close to the rubber cotton head, the force applied by the movable sleeve 30 causes the handle 43 to continue to move in the direction close to the holding rod 20, that is, the handle 43 and the hinge seat 41 can always remain in the initial position, and the pull rod 42 can directly transmit the force applied by the movable sleeve 30 to the cotton head assembly 10 along the axial direction of the holding rod 20, thereby realizing the automatic disassembly of the cotton head assembly 10.

[0065] It should be noted that, in this embodiment, no matter the pull rod 42 is a straight rod-shaped structure or a curved rod-shaped structure, in the initial state, the hinge point of the pull rod 42 and the hinge seat 41 is located below the central axis of the gripping rod 20. It should be further explained that, in this embodiment, the upper, lower, upper side, lower side, etc. of the gripping rod 20 involved are all referred to in Figure 3 , Figure 8As shown, the top, bottom, upper side and lower side of the gripping rod 20 in this embodiment are relative to the radial direction of the gripping rod 20, wherein the side where the handle 43 is located is defined as the top and upper side of the gripping rod 20, and the side of the gripping rod 20 away from the handle 43 is defined as the bottom and lower side of the gripping rod 20.

[0066] In some embodiments, the hinge seat 41 includes a hinge plate; the number of hinge plates is set to two, the two hinge plates are arranged opposite to each other and are respectively arranged on both sides of the handle 43; there are two pull rods 42, the first ends of the two pull rods 42 are respectively hinged on the two hinge plates, and the second ends of the two pull rods 42 are respectively connected to the corresponding positions of the cotton head assembly 10.

[0067] In the above embodiment, by adopting two hinged plates arranged relatively to each other, the pull rod 42 is correspondingly arranged in two, and the two pull rods 42 and the two hinged plates are distributed on both sides of the holding rod 20. The two pull rods 42 and the two hinged plates are correspondingly connected to the handle 43 and the two sides of the cotton head assembly 10. This design makes the handle 43 more balanced and stable when driving the cotton head assembly 10 to move.

[0068] Specifically, the two hinge plates and the two pull rods 42 are symmetrically arranged about the central axis of the gripping rod 20, and the hinge plates are integrally formed with the handle 43. The hinge plates include a strip-shaped plate-like body, and the length of the hinge plates is greater than the diameter of the gripping rod 20. The pull rod 42 is hinged at one end of the hinge plate away from the handle 43.

[0069] In some embodiments, a first hinge portion is disposed on the hinge plate; a second hinge portion is disposed on the pull rod 42; and the first hinge portion and the second hinge portion are hinged to each other.

[0070] In the above embodiment, the hinge plate and the pull rod 42 are connected by a first hinge portion provided on the hinge plate and a second hinge portion provided on the pull rod 42, and the first hinge portion and the second hinge portion are hinged to each other.

[0071] In some embodiments, the first hinge portion includes a hinge shaft 411 ; the second hinge portion includes a hinge ring 423 .

[0072] In the above embodiment, the first hinged part and the second hinged part are connected more conveniently and quickly by adopting the form of hinge shaft 411 and hinge ring 423 .

[0073] Specifically, the hinge shaft 411 is fixedly arranged on the outer wall of the hinge plate, and the central axis direction of the hinge shaft 411 is parallel to the radial direction of the holding rod 20. The first end of the pull rod 42 is integrally formed with a hinge ring 423, and the hinge ring 423 is rotatably sleeved on the hinge shaft 411, thereby realizing the hinge connection between the hinge plate and the pull rod 42.

[0074] Of course, in other alternative implementations, the first hinged portion and the second hinged portion may also adopt a structural form such as a hinge shaft or a hinge hole, which is not limited in this embodiment.

[0075] Preferably, the second hinged portion adopts a hinge ring 423 structure, which can minimize the width of the pull rod 42 compared to the opening method, thereby achieving the purpose of weight reduction and saving material costs.

[0076] In some embodiments, in combination Figure 5 , Figure 6 As shown, a slot 4111 is provided in the middle of the end of the hinge shaft 411. By providing the slot 4111 in the middle of the end of the hinge shaft 411, when the hinge ring 423 is connected to or removed from the hinge shaft 411, the hinge shaft 411 is squeezed by the hinge ring 423, and is more likely to deform and shrink inward, thereby making it easier to disassemble and assemble the hinge shaft 411 and the hinge ring 423, thereby improving assembly efficiency.

[0077] In some embodiments, a conical guide portion 4112 is provided at the end of the hinge shaft 411. The conical guide portion 4112 provided at the end of the hinge shaft 411 can play a guiding role, so that the hinge shaft 411 and the hinge ring 423 can be quickly positioned, further improving the assembly efficiency of the hinge shaft 411 and the hinge ring 423.

[0078] Specifically, the conical guide portion 4112 is truncated cone-shaped, and the hinge shaft 411 includes a root, a hinge portion, and a conical guide portion 4112. The hinge portion is located between the conical guide portion 4112 and the root, and the cross section of the conical guide portion 4112 gradually decreases from the hinge plate to the outside. The root is fixed on the hinge plate, the outer diameter of the hinge portion is smaller than the outer diameter of the root, and the outer diameter of the hinge portion is smaller than the maximum outer diameter of the conical guide portion 4112. The outer peripheral shape and size of the hinge portion match the inner peripheral shape and size of the hinge ring 423. The hinge ring 423 is clamped on the hinge portion and limited between the root and the conical guide portion 4112.

[0079] Furthermore, in this embodiment, the design of the groove 4111 makes the conical guide portion 4112 have two states, namely a normal state and a contracted state with a reduced outer diameter. When the conical guide portion 4112 is squeezed by the hinge ring 423, it contracts inwardly to the contracted state, thereby making it easier to disassemble the hinge ring 423 and the hinge shaft 411; when the hinge ring 423 is assembled to the hinge portion in the middle of the hinge shaft 411, the conical guide portion 4112 is not squeezed by the hinge ring 423 and automatically resets to a normal state. In the normal state, the maximum outer diameter of the conical guide portion 4112 is greater than the inner diameter of the hinge ring 423, thereby being able to limit the hinge ring 423 and prevent the hinge ring 423 from falling off the hinge shaft 411.

[0080] Furthermore, a stepped through hole is provided in the hinge ring 423, and the stepped through hole is rotatably sleeved on the hinge part and forms a limit with the tapered guide part 4112. Specifically, the stepped through hole includes a first aperture section and a second aperture section, and the aperture of the first aperture section is smaller than the aperture of the second aperture section; the outer diameter of the hinge part is smaller than the aperture of the first aperture section, and the maximum outer diameter of the tapered guide part 4112 under normal conditions is between the aperture of the first aperture section and the aperture of the second aperture section. The inner circumference of the second aperture section and the stepped surface between the first aperture section and the second aperture section enclose to form a stepped accommodating groove, and the hole depth of the second aperture section is greater than the length of the tapered guide part 4112. The stepped accommodating groove can accommodate the tapered guide part 4112, so that the tapered guide part 4112 can be hidden in the stepped accommodating groove, which not only improves the aesthetics, but also avoids the problem that the tapered guide part 4112 is exposed and easily interferes with other components.

[0081] In some embodiments, the handle 43 includes a support body 431 and a hinge structure 432 and a pull ring portion 433 arranged at both ends of the support body 431; the support body 431 includes a straight portion and an arc-shaped portion, and the straight portion is connected between the arc-shaped portion and the pull ring portion 433; the handle 43 is hinged to the movable sleeve 30 through the hinge structure 432; the hinge structure 432 is arranged on the end of the arc-shaped portion, and / or the hinge seat 41 is fixedly arranged on the straight portion.

[0082] In the above embodiment, the supporting body 431 of the handle 43 is designed with an arc portion to facilitate the connection between the handle 43 and the movable sleeve 30, and is designed with a straight portion to facilitate the connection between the hinge seat 41 and the handle 43.

[0083] Specifically, the hinge structure 432 can be in the form of a hinge shaft, a hinge hole, a hinge ring, etc. The straight portion is plate-shaped, the arc-shaped portion is rod-shaped, and there are two arc-shaped portions, which are arranged on both sides of the straight portion, and the hinge structure 432 is also two groups. Two groups of hinge matching structures are arranged on both sides of the movable sleeve 30 corresponding to the two groups of hinge structures 432. The handle 43 is hinged on both sides of the movable sleeve 30 through the two groups of hinge structures 432 and the two groups of hinge matching structures, so that the movable sleeve 30 is more balanced and stable when subjected to force during movement.

[0084] In some embodiments, the cotton head assembly 10 includes a cotton head and a mounting structure; the cotton head is detachably arranged on the mounting structure, and the movable sleeve 30 has a locked state and a released state; when the movable sleeve 30 is in the locked state, the cleaning structure can perform cleaning or water squeezing operations; when the movable sleeve 30 is in the released state, the movable sleeve 30 moves toward the direction close to the cotton head, and drives the pull rod 42 to bend or bend the middle part of the cotton head away from the holding rod 20, thereby realizing automatic disassembly of the cotton head.

[0085] In the above embodiment, the cotton head assembly 10 adopts a mounting structure and a design of a detachable cotton head disposed on the mounting structure, which facilitates the installation and fixation of the cotton head on the one hand, and also facilitates the automatic disassembly of the cotton head on the other hand.

[0086] In some embodiments, the cleaning structure comprises a mop or a glass cleaner. Preferably, in this embodiment, the cleaning structure is a mop.

[0087] In the present application, the pull rod can be made of materials such as plastic or metal.

[0088] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
