Description

TECHNICAL FIELD

[0001] The utility model relates to a cleaning article technical field, especially a kind of cleaning structure. BACKGROUND

[0002] In the field of cleaning tools, with the continuous improvement of people's requirements for cleaning efficiency and convenience, traditional single-function cleaning tools gradually cannot meet the diversified cleaning needs.For example, in common floor cleaning tools, broom is only suitable for cleaning dry light garbage and dust, mop is mainly used for cleaning stains, but for different ground materials such as ceramic tile, wood floor, carpet, etc., single mop or broom function is limited.

[0003] Some combined cleaning tools have appeared on the market, which are usually designed as detachable cleaning components with different functions, and users need to manually replace the cleaning head to adapt to different cleaning tasks.This way may increase the functional diversity to some extent, but it is cumbersome to operate, and users need to stop cleaning, spend time on cleaning head disassembly and installation, and in the replacement process, cleaning head and connecting components are easy to be contaminated with dust and dirt, which not only affects the cleaning effect, but also may cause the service life of cleaning tool to be shortened.

[0004] In addition, some existing cleaning devices with automatic switching function are often complex in structure and high in cost, and are mainly applied to professional cleaning robots and other devices in large commercial cleaning field, which are not suitable for ordinary household consumer market.For example, although some high-end sweeping robots can automatically switch different cleaning modes and cleaning heads, they are expensive and have low popularization rate.

[0005] Therefore, how to provide a cleaning structure with simple operation, low cost and meeting various cleaning needs has become a technical problem urgently to be solved by the technical personnel in the field. CONTENT OF UTILITY MODEL

[0006] The utility model aims at at least solving one of the technical problems existing in the prior art.Therefore, one purpose of the utility model is to provide a cleaning structure, comprising:

[0007] Base; base is provided with mounting cavity, and mounting cavity has outlet;

[0008] First cleaning head and second cleaning head; first cleaning head and second cleaning head can be extended or retracted into mounting cavity through outlet;

[0009] The rotating structure is rotatably arranged on the base. The rotating structure has an initial position. The rotating structure rotates from the initial position to a first direction, which can drive the first cleaning head to extend out of the installation cavity while the second cleaning head retracts into the installation cavity. The rotating structure rotates from the initial position to a second direction, which can drive the first cleaning head to retract into the installation cavity while the second cleaning head extends out of the installation cavity. The first direction and the second direction are different directions.

[0010] Beneficial effects: The rotating structure rotates in different directions to drive the first cleaning head or the second cleaning head to extend out of the installation cavity or retract into the installation cavity through the outlet. The application can select one cleaning head to work and the other to retract according to actual cleaning needs, which increases the functional diversity of the cleaning tool. The application is simple to operate, low in cost, and can meet various cleaning needs.

[0011] Further, when the rotating structure is located at the initial position, the first cleaning head and the second cleaning head are retracted into the installation cavity or flush with the outlet.

[0012] Beneficial effects: The cleaning structure also has a storage state, i.e., the first cleaning head and the second cleaning head cannot be used, which can prevent the first cleaning head or the second cleaning head from being damaged during transportation or standby state.

[0013] Further, the cleaning structure further comprises a first mounting member and a second mounting member, and the first cleaning head and the second cleaning head are arranged on the first mounting member and the second mounting member, respectively. The first mounting member and the second mounting member are movably arranged in the installation cavity to drive the first cleaning head and the second cleaning head to extend out or retract into the installation cavity.

[0014] Beneficial effects: The first mounting member and the second mounting member are driven to drive the first cleaning head and the second cleaning head, which is simple to install and convenient to drive.

[0015] Further, the rotating structure is provided with a driving member, the first mounting member is provided with a first guide hole, and the second mounting member is provided with a second guide hole. The driving member extends into the first guide hole and the second guide hole at the same time. The rotation of the rotating structure can drive the driving member to move. The movement of the driving member can drive the first mounting member and the second mounting member to move in the installation cavity through the first guide hole and the second guide hole, respectively, thereby driving the first cleaning head and the second cleaning head to extend out or retract into the installation cavity.

[0016] Beneficial effects: Since the driving member extends into the first guide hole and the second guide hole at the same time, the driving member rotates when the rotating structure rotates. At this time, the driving member can drive the first mounting member to move through the first guide hole and drive the second mounting member to move through the second guide hole. This driving method is more reliable and stable, which effectively ensures the extension and retraction of the first cleaning head and the second cleaning head.

[0017] Further, the first guide hole comprises a first inclined hole, a cross section of the first inclined hole is a first strip-shaped hole; the second guide hole comprises a second inclined hole, a cross section of the second inclined hole is a second strip-shaped hole; in the first direction, the first strip-shaped hole gradually inclines in a direction away from the outlet, and the second strip-shaped hole gradually inclines in a direction close to the outlet; the driving member is movable in the first inclined hole to drive the first mounting member to move in a direction close to or away from the outlet, thereby driving the first cleaning head to extend out of or retract into the mounting cavity; the driving member is movable in the second inclined hole to drive the second mounting member to move in a direction close to or away from the outlet, thereby driving the second cleaning head to extend out of or retract into the mounting cavity.

[0018] Beneficial effects: since the driving member rotates with the rotation of the rotating structure, and the driving member extends into the first guide hole and the second guide hole at the same time; when the rotating structure rotates, the driving member moves along the path defined by the first guide hole and the second guide hole, and since the movement of the driving member is circumferential movement, the existence of the first inclined hole and the second inclined hole can convert the circumferential movement of the driving member into axial movement of the first mounting member and the second mounting member, so as to ensure the extension and retraction of the first cleaning head and the second cleaning head; through the limitation of the guide hole on the movement direction of the driving member, the movement trajectory of the first mounting member and the second mounting member can be ensured to be very accurate, thereby making the extension and retraction of the first cleaning head and the second cleaning head accurate and stable, avoiding the situation that the cleaning head moves deviatedly to cause the cleaning head to be unable to normally extend out of or retract into the mounting cavity or collide with the inner wall of the mounting cavity, and ensuring the reliability of the operation of the entire cleaning structure.

[0019] Further, the first inclined hole has a first middle position between the two ends of the first inclined hole; the second inclined hole has a second middle position between the two ends of the second inclined hole; in the axial direction of the outlet, the two ends of the first inclined hole correspond to the two ends of the second inclined hole respectively, and the first middle position and the second middle position correspond to each other; when the rotating structure is located at the initial position, the driving member is located at the first middle position and the second middle position at the same time.

[0020] Beneficial effects: when the rotating structure is located at the initial position, the driving member is located at the first middle position and the second middle position at the same time, which is a starting and reference state of the entire cleaning structure; at this time, the cleaning head is in a relatively stable and balanced standby state, and the first cleaning head and the second cleaning head neither have a tendency to extend out nor have a tendency to retract; in this state, the driving member is just located at the corresponding middle positions of the two inclined holes, like a “balance point”, and the subsequent rotation of the rotating structure will break this balance, so that the driving member moves in the inclined hole, thereby driving the two cleaning heads to extend and retract respectively, to realize the switching of the two cleaning heads.

[0021] Further, the first guide hole further comprises a first circumferential extension hole; the second guide hole further comprises a second circumferential extension hole; in the first direction, the first inclined hole and the first circumferential extension hole are sequentially communicated, and the second circumferential extension hole and the second inclined hole are sequentially communicated; in the axial direction of the outlet, the first circumferential extension hole is arranged corresponding to the second inclined hole, and the second circumferential extension hole is arranged corresponding to the first inclined hole; in the cross section of the outlet, the orthographic projection of the first circumferential extension hole overlaps or covers the orthographic projection of the second inclined hole, and the orthographic projection of the second circumferential extension hole overlaps or covers the orthographic projection of the first inclined hole; when the rotating structure is located at the initial position, the driving member is simultaneously located in the first circumferential extension hole and the second circumferential extension hole.

[0022] Beneficial effects: when the rotating structure is located at the initial position, the driving member is simultaneously located in the first circumferential extension hole and the second circumferential extension hole, which is a reference state of the entire cleaning structure when the cleaning head switching operation has not started; the first circumferential extension hole and the second circumferential hole cannot change the activity direction of the driving member, at this time, the first mounting member and the second mounting member respectively carry the first cleaning head and the second cleaning head at the initial position, and when the rotating structure rotates to the first direction or the second direction, the driving member enters the first inclined hole or the second inclined hole, then under the action of the first inclined hole or the second inclined hole, the first mounting member or the second mounting member drives the first cleaning head or the second cleaning head to stretch or retract; this state ensures that the rotating structure is more stable at the initial state and is not easy to be misoperated.

[0023] Further, the base comprises a sleeve, an installation cavity is formed on the inner circumferential side of the sleeve, and a first end of the sleeve forms an outlet; the first cleaning head and the second cleaning head are telescopically arranged in the sleeve; and the rotating structure is rotatably arranged on the sleeve.

[0024] Beneficial effects: the installation cavity is the "activity site" of the two cleaning heads for stretching and retracting activities. It limits the activity range of the cleaning heads and components such as the mounting members connected thereto, so that the stretching and retracting actions of the cleaning heads can be carried out in this relatively closed and orderly space, avoiding problems such as deviation from the preset track and interference with external structures during the movement of the cleaning heads, ensuring the stability and reliability of the cleaning structure operation; and making the structure of the entire cleaning structure compact, the space utilization rate higher, and the volume of the entire product smaller, more convenient to carry, store and use.

[0025] Further, the first mounting member comprises a first mounting cylinder, and the first cleaning head is arranged at one end of the first mounting cylinder; the first mounting cylinder is sleeved in the sleeve; the second cleaning head is arranged on the inner circumferential side of the first mounting cylinder; a first guide member is arranged between the sleeve and the first mounting cylinder, and the first guide member is used to guide the first mounting cylinder to move in the axial direction of the sleeve to drive the first cleaning head to stretch out or retract into the installation cavity.

[0026] Beneficial effects: the first guide is located between the sleeve and the first mounting cylinder, which determines that it plays a key role in the motion control of the entire cleaning structure; the movement of the first mounting cylinder is strictly in the axial direction of the sleeve, avoiding the influence of cleaning head normal extension and retraction caused by skewing, shaking or irregular motion.

[0027] Further, the second mounting member includes a second mounting cylinder, and the second cleaning head is arranged at one end of the second mounting cylinder; the second mounting cylinder is sleeved in the first mounting cylinder, and a second guide is arranged between the first mounting cylinder and the second mounting cylinder, and the second guide is used for guiding the relative movement of the first mounting cylinder and the second mounting cylinder in the axial direction of the sleeve.

[0028] Beneficial effects: the second guide is located between the first mounting cylinder and the second mounting cylinder, which determines that it plays a key role in the motion control of the entire cleaning structure; the movement of the first mounting cylinder and the second mounting cylinder is strictly in the axial direction of the sleeve, avoiding the influence of cleaning head normal extension and retraction caused by skewing, shaking or irregular motion.

[0029] Further, the first guide includes a first slot and a first protrusion which are matched with each other; one of the first slot and the first protrusion is arranged on the inner circumferential wall of the sleeve, and the other is arranged on the outer circumferential wall of the first mounting cylinder; and the first slot extends in the axial direction of the sleeve.

[0030] And / or, the second guide includes a second slot and a second protrusion which are matched with each other; one of the first slot and the second protrusion is arranged on the inner circumferential wall of the first mounting cylinder, and the other is arranged on the outer circumferential wall of the second mounting cylinder; and the second slot extends in the axial direction of the sleeve.

[0031] Beneficial effects: such a matched structure has good directionality and stability; once the first protrusion is embedded in the first slot, the first mounting cylinder can only move in the direction defined by the first slot under normal circumstances, effectively avoiding unnecessary displacement or shaking in other directions, and ensuring the accuracy and reliability of the movement of the entire cleaning structure; similarly, the cooperation of the second protrusion and the second slot is also the same.

[0032] Further, the rotating structure includes a rotating cover, and the rotating cover is arranged at the second end of the sleeve and is rotatably connected with the sleeve; the rotating cover includes an end cover and a first axial extension which are connected with each other.

[0033] The end cover is rotatably connected with the second end of the sleeve; the first axial extension extends into the inner circumferential side of the sleeve, and a driving member is arranged on the first axial extension and extends into the first guide hole and the second guide hole at the same time.

[0034] Alternatively, the first axial extension extends into the sleeve, and the driving member is arranged on the outer peripheral wall of the first axial extension; a limiting groove is arranged on the inner peripheral wall of the sleeve; the limiting groove extends in the circumferential direction of the sleeve; the driving member sequentially passes through the second guide hole and the first guide hole, and is limited in the limiting groove; the limiting groove limits the movement of the driving member in the axial direction of the sleeve, and can guide the movement of the driving member in the circumferential direction of the sleeve; the driving member can relatively move in the first guide hole and the second guide hole when moving in the limiting groove, so as to drive the first mounting member and the second mounting member to move in the mounting cavity, respectively.

[0035] Beneficial effects: when the rotating cover rotates, the first axial extension rotates, and the driving member arranged thereon moves together, and the driving member extends into the first guide hole and the second guide hole at the same time. By moving in these guide holes, the corresponding mounting member can be driven to move, and the cleaning head can be driven to perform the telescopic action, so as to realize the switching function of the cleaning head. The rotating movement of the rotating cover is converted into the axial telescopic movement of the cleaning head, which completes the key link of power transmission and function conversion of the entire cleaning structure. The above technical solution can ensure the accurate switching of the first cleaning head and the second cleaning head.

[0036] Further, the rotating structure comprises a rotating ring, and the rotating ring is sleeved outside the sleeve; a through hole is formed in the side wall of the sleeve, and the through hole is an arc-shaped hole or a ring-shaped hole extending in the circumferential direction of the sleeve; the driving member is arranged on the inner peripheral wall of the rotating ring; the driving member extends into the sleeve through the through hole, and sequentially passes through the first guide hole and the second guide hole.

[0037] Beneficial effects: by using the relatively simple structure of the rotating ring, the sleeve through hole and the driving member, the switching function of the cleaning head is realized. The user only needs to rotate the rotating ring, which is an external visible and easy-to-operate component, to easily control the telescopic switching of the cleaning head. The entire operation process is intuitive and easy to understand, and does not require complex operation steps or professional knowledge, which meets the needs of ordinary consumers for convenient use of cleaning tools. Moreover, the rotating ring is sleeved outside the sleeve, which fully utilizes the space on the outer periphery of the sleeve and does not occupy too much additional space, so that the entire cleaning structure can still maintain a relatively compact form, facilitating carrying and storage. At the same time, this layout around the sleeve is relatively stable during rotation and is not prone to eccentricity, shaking and other factors that affect the accuracy of the switching of the cleaning head, thereby ensuring the reliability of the operation of the cleaning structure.

[0038] Further, the first cleaning head comprises a sponge; and / or, the second cleaning head comprises bristles; and / or, the first direction is a clockwise rotation direction, and the second direction is a counterclockwise rotation direction.

[0039] Beneficial effects: By setting the sponge on the first cleaning head and the bristles on the second cleaning head, the cleaning structure has two different characteristics of cleaning function, which can deal with various types of stains and cleaning surfaces, without frequent replacement of different cleaning tools, greatly improving the cleaning efficiency.

[0040] The cleaning structure of the utility model, through the rotation structure rotates in different directions, thereby drive the first cleaning head or the second cleaning head can realize the extension installation cavity or the retraction installation cavity through the outlet;Then the application can select one of the cleaning heads to work according to the actual cleaning demand, and the other is retracted and not used, which increases the functional diversity of the cleaning tool.

DETAILED DESCRIPTION

[0051] Embodiments of the present application are described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are for the purpose of explaining the present application only and are not to be understood as limiting the present application.

[0052] Reference is made below Figures 1-6 A cleaning structure according to embodiments of the present application is described.

[0053] As Figures 1-6As shown, the application discloses a cleaning structure, which comprises a base 1, a first cleaning head 2 and a second cleaning head 3, and a rotating structure 4; the base 1 is provided with a mounting cavity, and the mounting cavity has an outlet; the first cleaning head 2 and the second cleaning head 3 can extend out of or retract into the mounting cavity through the outlet; the rotating structure 4 is rotatably arranged on the base 1; the rotating structure 4 has an initial position; the rotating structure 4 rotates from the initial position to a first direction, and can drive the first cleaning head 2 to extend out of the mounting cavity while the second cleaning head 3 retracts into the mounting cavity; the rotating structure 4 rotates from the initial position to a second direction, and can drive the first cleaning head 2 to retract into the mounting cavity while the second cleaning head 3 extends out of the mounting cavity; wherein the first direction and the second direction are different directions. The application drives the first cleaning head 2 or the second cleaning head 3 to extend out of or retract into the mounting cavity through the outlet by rotating the rotating structure 4 in different directions; then the application can select one cleaning head to extend out for work according to actual cleaning requirements, and the other cleaning head is retracted and not used, which increases the functional diversity of the cleaning tool. The application has the advantages of simple operation, low cost and meeting various cleaning requirements. The technical scheme of the application can easily switch different cleaning heads, so that the cleaning structure can be suitable for various cleaning scenes and surface materials, without the need of preparing multiple different cleaning tools, and the cleaning efficiency and convenience are improved. For example, when cleaning at home, the cleaning structure can be quickly switched from cleaning ceramic tile floor to cleaning carpet, and only the rotating structure 4 needs to be rotated. The two cleaning heads can be stored in the mounting cavity, and compared with a cleaning tool which is separately provided with two different cleaning heads and is externally placed, the overall structure is more compact, the space occupied during storage is smaller, and storage is facilitated. In the application, a plurality of cleaning heads such as a third cleaning head and a fourth cleaning head can be further included, and the cleaning heads can be the same or different; when the cleaning heads are the same, one cleaning head can be damaged, and the remaining cleaning heads can be switched by rotating the rotating structure 4; when the cleaning heads are different, different cleaning heads can be switched by rotating the rotating structure 4 to cope with different cleaning scenes.

[0054] In some embodiments, the first cleaning head 2 can be a brush cleaning head suitable for cleaning hard ground, and the second cleaning head 3 can be a dust cleaning head for cleaning carpet, and the two cleaning heads can be switched according to different ground materials.

[0055] In some other embodiments, the first cleaning head 2 can be a scraping strip, and the second cleaning head 3 can be a cotton cloth cleaning head or a sponge cleaning head; the first cleaning head 2 can be used to scrape water on a glass, a ground or other surface, and then the sponge or the cloth cleaning head can be switched by the rotating structure 4 to wipe the surface.

[0056] In some embodiments, the first cleaning head 2 can be a steel wire brush cleaning head, and the second cleaning head 3 can be a cotton cleaning head. In this case, the cleaning structure can be used to clean kitchen utensils such as pots and bowls. The first cleaning head 2 is used to clean stains on the kitchen utensils. After the kitchen utensils are washed, the rotating structure 4 is switched to the cotton cleaning head to dry the kitchen utensils.

[0057] In some embodiments, the rotating structure 4 is rotatably mounted on the base 1 and has an initial position as a key setting. When it rotates in the first direction, it acts as a "switch" to push the first cleaning head 2 to extend out of the mounting cavity while the second cleaning head 3 is retracted. Conversely, when it rotates in the second direction, the first cleaning head 2 is retracted and the second cleaning head 3 is extended. For example, the rotating structure 4 can be a disc-shaped component with a lever or knob. By manually rotating the lever or knob, the rotating structure 4 can be rotated in different directions to control the extension and retraction of the cleaning heads.

[0058] The present application can easily switch between different cleaning heads, so that the cleaning structure can be suitable for a variety of different cleaning scenarios and surface materials, without the need to prepare multiple different cleaning tools, improving cleaning efficiency and convenience. For example, when cleaning at home, you can quickly switch from cleaning ceramic tile floors to cleaning carpets by rotating the rotating structure 4. The two cleaning heads can be stored in the mounting cavity. Compared with separate cleaning tools with two different cleaning heads and external placement, the overall structure is more compact and occupies less space when stored, making it easier to store.

[0059] The present application can be applied to handheld multifunctional cleaners, such as detachable cleaning components of a sweeping robot, or brush head switching devices for handheld multifunctional cleaning tools for floors, tables, etc., to meet the cleaning needs of different surfaces in daily household cleaning.

[0060] The present application is also useful in cleaning work in hotels, shopping malls and other places. Cleaning personnel can use such a cleaning structure to quickly switch cleaning heads to handle cleaning tasks in different areas such as lobby floors (which may be made of materials such as marble), corridor carpets, etc., to improve work efficiency.

[0061] In the present application, the cleaning head can be switched by manually rotating the rotating structure 4. Alternatively, it can be combined with an electric motor, a sensor, etc. to automatically sense and switch the cleaning head according to different cleaning surface materials, improving the degree of intelligence and convenience of use.

[0062] The application also discloses some embodiments, when the rotating structure 4 is located at the initial position, the first cleaning head 2 and the second cleaning head 3 are retracted into the installation cavity or are flush with the outlet. The cleaning structure also has a storage state, that is, the first cleaning head 2 and the second cleaning head 3 are retracted into the installation cavity or are flush with the outlet; at this time, the first cleaning head 2 and the second cleaning head 3 cannot be used, and damage to the first cleaning head 2 or the second cleaning head 3 can be prevented in the transportation or standby state.

[0063] The application also discloses some embodiments, the cleaning structure further comprises a first mounting member 21 and a second mounting member 31, and the first cleaning head 2 and the second cleaning head 3 are arranged on the first mounting member 21 and the second mounting member 31 respectively; the first mounting member 21 and the second mounting member 31 are movably arranged in the installation cavity, so as to drive the first cleaning head 2 and the second cleaning head 3 to extend out of or retract into the installation cavity. The first mounting member 21 and the second mounting member 31 are driven to drive the first cleaning head 2 and the second cleaning head 3, the installation is simple, and the driving is convenient. The driving member 41 is arranged on the rotating structure 4, and the driving member 41 plays a key transmission role, that is, the driving member 41 is like an "movable bridge" and transmits the rotating action of the rotating structure 4 to promote the corresponding movement of other components. For example, the driving member 41 can be a columnar protruding structure or a special sliding block.

[0064] The application also discloses some embodiments, the rotating structure 4 is provided with a driving member 41, the first mounting member 21 is provided with a first guide hole 211, and the second mounting member 31 is provided with a second guide hole 311; the driving member 41 extends into the first guide hole 211 and the second guide hole 311 simultaneously, the rotating structure 4 rotates to drive the driving member 41 to move, the driving member 41 moves to drive the first mounting member 21 and the second mounting member 31 to move in the installation cavity through the first guide hole 211 and the second guide hole 311 respectively, and then the first cleaning head 2 and the second cleaning head 3 can extend out of or retract into the installation cavity. Since the driving member 41 extends into the first guide hole 211 and the second guide hole 311 simultaneously, the driving member 41 rotates with the rotating structure 4 when the rotating structure 4 rotates, at this time, the driving member 41 can drive the first mounting member 21 to move through the first guide hole 211 and drive the second mounting member 31 to move through the second guide hole 311, and the driving mode is more reliable and stable.

[0065] In some embodiments, the driving member 41 is a driving block, the rotating structure 4 rotates to drive the driving member 41 to rotate; the driving member 41 can move in the first guide hole 211 and the second guide hole 311; the driving member 41 moves in the first guide hole 211 and the second guide hole 311 to drive the first mounting member 21 and the second mounting member 31 to move, and then the first cleaning head 2 and the second cleaning head 3 can extend or retract in the installation cavity.

[0066] The application further discloses some embodiments, the first guide hole 211 comprises a first inclined hole 2111, the cross section of the first inclined hole 2111 is a first strip-shaped hole; the second guide hole 311 comprises a second inclined hole 3111, the cross section of the second inclined hole 3111 is a second strip-shaped hole; in the first direction, the first strip-shaped hole gradually inclines to the direction away from the outlet, and the second strip-shaped hole gradually inclines to the direction close to the outlet; the driving member 41 can move in the first inclined hole 2111, so as to drive the first mounting member 21 to move in the direction close to or away from the outlet, and then drive the first cleaning head 2 to extend out of or retract into the mounting cavity; the driving member 41 can move in the second inclined hole 3111, so as to drive the second mounting member 31 to move in the direction close to or away from the outlet, and then drive the second cleaning head 3 to extend out of or retract into the mounting cavity. Since the driving member 41 rotates along with the rotation of the rotating structure 4, and the driving member 41 extends into the first guide hole 211 and the second guide hole 311 at the same time, when the rotating structure 4 rotates, the driving member 41 moves along the path defined by the first guide hole 211 and the second guide hole 311, and since the movement of the driving member 41 is the circumferential movement, the existence of the first inclined hole 2111 and the second inclined hole 3111 can convert the circumferential movement of the driving member 41 into the axial movement of the first mounting member 21 and the second mounting member 31, so as to ensure the extension and retraction of the first cleaning head 2 and the second cleaning head 3; through the limitation of the guide hole on the movement direction of the driving member 41, the movement track of the first mounting member 21 and the second mounting member 31 can be ensured to be very accurate, and then the extension and retraction of the first cleaning head 2 and the second cleaning head 3 are accurate and stable, the movement deviation of the cleaning head can be avoided, and the cleaning head cannot normally extend out of or retract into the mounting cavity or collide with the inner wall of the mounting cavity and the like, and the reliability of the whole cleaning structure is ensured. The first strip-shaped hole is a straight strip-shaped hole or a curved strip-shaped hole; in the first direction, the first strip-shaped hole can gradually incline to the direction away from the outlet, and the inclination can be straight inclination or curved inclination such as arc shape; the second strip-shaped hole can also be a straight strip-shaped hole or a curved strip-shaped hole; in the first direction, the second strip-shaped hole can gradually incline to the direction close to the outlet.

[0067] In combination Figures 4-6As shown, this application also discloses some embodiments, wherein the first inclined hole 2111 has a first central position, which is located between the two ends of the first inclined hole 2111; the second inclined hole 3111 has a second central position, which is located between the two ends of the second inclined hole 3111; in the axial direction of the outlet, the two ends of the first inclined hole 2111 correspond to the two ends of the second inclined hole 3111 respectively, and the first central position and the second central position correspond to each other; when the rotating structure 4 is in the initial position, the driving member 41 is simultaneously located in the first central position and the second central position. When the rotating structure 4 is in the initial position, the driving member 41 is simultaneously located in the first central position and the second central position, which is a starting, reference state of the entire cleaning structure. At this time, the cleaning head is in a relatively stable and balanced standby state. The first cleaning head 2 and the second cleaning head 3 neither extend nor retract. The driving component 41 is located at the corresponding midpoint of the two inclined holes, like a "balance point." The subsequent rotation of the rotating structure 4 will break this balance, causing the driving component 41 to move within the inclined holes, thereby driving the cleaning head to perform the extension and retraction switching action. At this time, when the rotating structure 4 rotates in the first or second direction, the movable component moves simultaneously within the first inclined hole 2111 and the second inclined hole 3111, which can simultaneously drive the first mounting component 21 and the second mounting component 31 to move, that is, simultaneously drive the first cleaning head 2 and the second cleaning head 3 to extend or retract into the mounting cavity respectively.

[0068] In some embodiments, the first middle position is located at the middle position in the length direction of the first inclined hole 2111; at this time, the second middle position can be located at the middle position in the length direction of the second inclined hole 3111, or it can be located at a position near one end in the length direction of the second inclined hole 3111.

[0070] exist Figure 6 In the initial position, the rotating structure 4 is in the retracted state, with both the first cleaning head 2 and the second cleaning head 3 retracted into the mounting cavity or flush with the outlet. The rotating structure 4 rotates in the first direction, and the driving component 41 moves to... Figure 4 The position is such that the first cleaning head 2 extends and the second cleaning head 3 retracts into the mounting cavity; the rotating structure 4 rotates in the second direction, and the driving member 41 can move to... Figure 5 The position is such that the second cleaning head 3 extends out and the first cleaning head 2 retracts into the mounting cavity.

[0071] like Figure 1As shown, the application further discloses some embodiments, the first guide hole 211 further comprises a first circumferential extension hole 2112; the second guide hole 311 further comprises a second circumferential extension hole 3112; in the first direction, the first inclined hole 2111 and the first circumferential extension hole 2112 are sequentially communicated, and the second circumferential extension hole 3112 and the second inclined hole 3111 are sequentially communicated; in the axial direction of the outlet, the first circumferential extension hole 2112 is arranged corresponding to the second inclined hole 3111, and the second circumferential extension hole 3112 is arranged corresponding to the first inclined hole 2111; in the cross section of the outlet, the orthographic projection of the first circumferential extension hole 2112 overlaps or covers the orthographic projection of the second inclined hole 3111, and the orthographic projection of the second circumferential extension hole 3112 overlaps or covers the orthographic projection of the first inclined hole 2111; when the rotating structure 4 is located at the initial position, the driving member 41 is located in the first circumferential extension hole 2112 and the second circumferential extension hole 3112 at the same time. When the rotating structure 4 is located at the initial position, the driving member 41 is located in the first circumferential extension hole 2112 and the second circumferential extension hole 3112 at the same time, which is a reference state of the entire cleaning structure when it does not start the cleaning head switching operation; at this time, the first circumferential extension hole 2112 and the second circumferential hole cannot change the activity direction of the driving member 41, and the first mounting member 21 and the second mounting member 31 respectively carry the first cleaning head 2 and the second cleaning head 3 at the initial position at this time, and when the rotating structure 4 rotates to the first direction or the second direction, the driving member 41 enters the first inclined hole 2111 or the second inclined hole 3111, which will cause the first mounting member 21 or the second mounting member 31 to drive the first cleaning head 2 or the second cleaning head 3 to stretch or retract; this state ensures that the rotating structure 4 is more stable at the initial state and is not easy to be misoperated. The first mounting member 21 can be a first arc-shaped member, and the first circumferential extension hole 2112 extends in the circumferential direction of the first arc-shaped member; the second mounting member 31 can be a second arc-shaped member, and the second circumferential extension hole 3112 extends in the circumferential direction of the second arc-shaped member. The first arc-shaped member, the second arc-shaped member and the side wall of the mounting cavity are concentric circles. In the application, the "axial direction of the outlet" refers to the direction perpendicular to the outlet cross section.

[0072] The application also discloses some embodiments, the base 1 comprises a sleeve, the inner circumferential side of the sleeve forms a mounting cavity, and the first end of the sleeve forms an outlet; the first cleaning head 2 and the second cleaning head 3 are telescopically arranged in the sleeve; and the rotating structure 4 is rotatably arranged on the sleeve. The sleeve is a key component of the base 1, and is generally in a cylindrical shape, having the structural characteristics of an inner circumferential side, an outer circumferential side and two ends. The space surrounded by the inner circumferential side forms the mounting cavity, which provides a necessary space for the telescopic movement of the cleaning heads in the entire cleaning structure, like a special "active area", limiting the movement range of the cleaning heads, ensuring that they can orderly perform telescopic movement according to the design requirements, and without position deviation or interference with other irrelevant components. The outlet formed by the first end of the sleeve is an important channel for the cleaning heads to contact the external environment. Its existence enables the cleaning heads to extend from the inside of the sleeve to the surface to be cleaned to work, and to be smoothly retracted into the sleeve through the outlet after the cleaning task is completed or when the cleaning heads need to be switched, realizing flexible switching and storage protection of the cleaning heads, and its size and shape are generally reasonably designed according to the size of the cleaning heads and other factors to ensure the smoothness of the telescopic movement of the cleaning heads. The first cleaning head 2 and the second cleaning head 3 are telescopically arranged in the sleeve, which reflects the flexibility and multifunctionality of the cleaning structure. In order to realize the telescopic function of the cleaning heads, a series of mechanical structures cooperating with the cleaning heads are necessarily involved, such as the mounting piece (such as the structure containing the mounting cylinder mentioned later) connecting the cleaning heads and the sleeve, and the guide piece (such as the structure of the strip-shaped groove cooperating with the protrusion) for guiding the mounting piece to move in the axial direction of the sleeve, and the like, which work cooperatively to convert the rotating movement of the rotating structure 4 into the telescopic movement of the cleaning heads along the axial direction of the sleeve, so that the cleaning heads can extend or retract into the mounting cavity as required. For example, when the user rotates the rotating structure 4 by a certain angle through operation, under the action of the related transmission components, the mounting piece connected with the cleaning head will move along the axial direction of the sleeve, thereby driving the cleaning head to extend out of the sleeve to start cleaning work; conversely, the rotating structure 4 is reversely rotated, the mounting piece drives the cleaning head to move reversely, and the cleaning head will be retracted into the sleeve.

The second guide 6 is located between the first mounting cylinder and the second mounting cylinder, and the position determines that the second guide 6 plays a key role in the motion control of the whole cleaning structure. The movement of the first mounting cylinder and the second mounting cylinder is strictly in the axial direction of the sleeve according to the design requirement, and the first mounting cylinder and the second mounting cylinder are prevented from moving in a skewed, shaking or irregular manner, which affects the normal extension and retraction of the cleaning head.

[0077] The application also discloses some embodiments, the second guide 6 comprises a second strip-shaped slot and a second protrusion which are matched with each other; one of the first strip-shaped slot and the second protrusion is arranged on the inner circumferential wall of the first mounting cylinder, and the other is arranged on the outer circumferential wall of the second mounting cylinder; and the second strip-shaped slot extends in the axial direction of the sleeve; at this time, the second protrusion can be a strip-shaped protrusion which is consistent with the extending direction of the second strip-shaped slot, or can be a block-shaped protrusion. The matched structure has good directivity and stability, once the first protrusion is embedded in the first strip-shaped slot, under normal circumstances, the first mounting cylinder can only move relatively along the direction defined by the first strip-shaped slot, effectively avoiding unnecessary displacement or shaking in other directions, and ensuring the accuracy and reliability of the movement of the whole cleaning structure; similarly, the cooperation of the second protrusion and the second strip-shaped slot is also the same.

[0078] The application also discloses some embodiments, the rotating structure 4 comprises a rotating cover which is arranged on the second end of the sleeve, and the rotating cover comprises an end cover and a first axial extension which are connected with each other; the end cover is rotationally connected with the second end of the sleeve; the first axial extension extends into the inner circumferential side of the sleeve, and the driving piece 41 is arranged on the first axial extension and extends into the first guide hole 211 and the second guide hole 311 at the same time; when the rotating cover rotates, the first axial extension rotates, and the driving piece 41 arranged thereon moves together, and the driving piece 41 extends into the first guide hole 211 and the second guide hole 311 at the same time, and through the movement in the guide holes, the corresponding mounting piece can be driven to move, and the cleaning head is driven to perform the telescopic action, so that the switching function of the cleaning head is realized, the rotating movement of the rotating cover is converted into the axial telescopic movement of the cleaning head, and the key link of power transmission and function conversion in the whole cleaning structure is completed; the above technical scheme can ensure the accurate switching of the first cleaning head 2 and the second cleaning head 3. The primary function of the end cover is to support and position the whole rotating cover, so that the rotating cover is stably arranged on the second end of the sleeve, and the relative stable space relationship between the rotating cover and the sleeve is maintained, so that a reliable basis is provided for the subsequent rotating operation and cooperation with other components. Design consideration for facilitating operation: from the perspective of user operation, the outer surface of the end cover can be provided with some designs which are convenient for the hand to hold and rotate, such as anti-skid textures, protrusions or recesses and the like, so that the user can exert force more easily and stably when rotating the rotating cover, the convenience and comfort of operation are enhanced, and the switching action of the cleaning head is better controlled.

[0080] In some embodiments, the end cap is directly rotationally connected with the second end of the sleeve.

[0081] In some embodiments, the end cap can be rotationally connected with the end face of the second end of the sleeve. A limiting block is arranged on the end cap or the second extension, and a necked slot is arranged on the end face of the second end of the sleeve, the necked slot refers to the slot width of the slot is less than the width in the slot, and the limiting block is arranged in the necked slot; the width of the limiting block corresponds to the width in the slot and is greater than the width of the slot neck, that is, the slot neck and the slot bottom jointly limit the movement of the end cap and the sleeve in the axial direction of the sleeve, preventing the end cap and the sleeve from being separated from each other; the necked slot extends in the circumferential direction of the sleeve, which can be a plurality of arc-shaped slots arranged in sequence, or a ring-shaped slot.

The structure is simpler, and the connection is more stable.

[0083] The driving member 41 is arranged on the first axial extension, which makes the first axial extension become a key component for transmitting rotational power. When the end cap rotates, the first axial extension will rotate synchronously, and then drive the driving member 41 arranged thereon to move together. For example, if the end cap rotates clockwise, the first axial extension will rotate in the same direction, and the driving member 41 will also make a corresponding circular motion, transmitting the rotational power of the end cap, providing a power source for the subsequent driving of the extension and retraction of the cleaning head. The first axial extension also has the function of connecting internal components: since the first axial extension extends to the inner peripheral side of the sleeve, it can directly contact the first guide hole 211, the second guide hole 311 and the related mounting member in the sleeve.

In addition, the rotating ring is arranged outside the sleeve, the space around the sleeve is fully utilized, and no additional space is occupied, so that the whole cleaning structure can still maintain a relatively compact form, and is convenient to carry and store. Meanwhile, the layout mode around the sleeve is relatively stable during the rotating process, and the eccentricity and shaking which affect the switching accuracy of the cleaning head are not prone to occur, so that the reliability of the cleaning structure is ensured.
