Description

FIELD

[0001] The present application relates to the technical field of shower device, and in particular, to a cleaning assembly and a shower device including the same.BACKGROUND

[0002] With the development of the home industry, more and more users choose shower rooms to separate dry and wet spaces.

[0003] In the conventional technology, a shower room limits overflow and sputtered liquid during showering to a specified space. The sputtered liquid adheres to and remains on a screen of the shower room to form water stains, which may easily breed bacteria over time, thereby affecting hygiene and aesthetics. Moreover, the liquid sputtered during showering includes impurities such as bath lotion and grease. These impurities further increase the stubbornness of water stains. The conventional towels and cleaning assemblies have small single cleaning areas and limited cleaning efficiency, so it is time-consuming and laborious to clean the screen of the shower room by using the conventional towels and cleaning assemblies.

[0004] Therefore, there is an urgent need for a cleaning assembly suitable for the shower room.SUMMARY

[0005] In view of this, the technical problem to be solved by the present application is to provide a cleaning assembly with high cleaning efficiency.

[0006] In one aspect, a cleaning assembly is provided according to an embodiment of the present application, which includes a base, a connecting arm, a first action arm and a second action arm, where a first end of the connecting arm is connected to the base; and a second end of the connecting arm is hinged to one end of the first action arm, to allow the first action arm to rotate around the second end; the second action arm is connected to the first action arm, and the second action arm is parallel to an extension axis of the first action arm, so as to allow the second action arm to slide along the extension axis relative to the first action arm; and a first cleaning element is provided on one side of the first action arm, and a second cleaning element is provided on one side of the second action arm.

[0007] According to the present application, the first action arm is hinged to the second end of the connecting arm through the above structure, so that the first action arm rotates around the second end in a plane where the connecting arm is located, and the second action arm connected to the first action arm is driven to rotate synchronously. When the first action arm rotates, the first cleaning element on the first action arm scrapes off water stains, and similarly, the second cleaning element on the second action arm also scrapes off water stains. In particular, the first action arm and the second action arm are connected to each other and can slide relative to each other axially, and an effective cleaning radius can be adjusted according to the dimension of a to-be-cleaned surface. For example, components such as a towel bar, a handle, a hinge or the like may be mounted on a screen of a shower room, and these existing components on the screen can be avoided by adjusting the length of an overlapping portion of the first action arm and the second action arm in the axial direction, so that cleaning is flexible. It should be noted that, the connection between the first end of the connecting arm and the base may be a detachable connection (for example, a threaded connection or a snap connection), or may be a fixed connection (for example, a connection by welding or riveting, etc.), or may be a hinged connection.

[0008] Optionally, the base includes a panel and a first connecting portion, and the first connecting portion is vertically arranged on one side of the panel.

[0009] According to an embodiment of the present application, the panel is configured for fixing the cleaning assembly, and may be pasted on a mounting surface or may be fixed to the mounting surface by a screw or a rivet. Generally, the mounting surface is flat, which may be a wall surface, a screen of a shower room, or a frame of a shower room. The first connecting portion may be a connecting rod, an insertion plate, a threaded hole, a hinge portion, or the like.

[0010] Optionally, the first end of the connecting arm and the first connecting portion form a first hinge; and a rotation axis of the first hinge is parallel to the panel, to allow the connecting arm to rotate in a first working plane perpendicular to the panel.

[0011] In this way, with the first hinge, the connecting arm can rotate in the plane perpendicular to the panel, and thereby driving the first action arm and the second action arm to rotate in the plane perpendicular to the panel. Therefore, a working surface of the first action arm and the second action arm may be a plane where the panel is located, or may be any plane that forms an angle with the panel. The cleaning assembly can clean a first to-be-cleaned surface A which forms an angle greater than or equal to 0 degree and less than or equal to 180 degrees with the panel, thereby increasing the degree of freedom of the cleaning assembly and realizing flexible deployment of the cleaning assembly.

[0012] Optionally, the cleaning assembly further includes an engagement member, and the engagement member includes a sliding portion and a fixing portion that are arranged in parallel with each other; where the sliding portion is a ring with an opening, and the fixing portion is of a cover-shaped structure; the sliding portion is engaged with a main body of the first action arm or a main body of the second action arm; and the fixing portion is connected to an end of the second action arm or an end of the first action arm.

[0013] According to the embodiment of the present application, the first action arm or the second action arm is engaged into an inner side of the sliding portion through the opening of the ring, so that the engagement member can slide along the extension axis of the first action arm or the second action arm. In the embodiment of the present application, the fixing portion is of a cover-shaped structure, and the cover-shaped structure is -connected in a sleeved manner to the end of the second action arm or the end of the first action arm, thereby preventing the axial movement of the second action arm or the first action arm. By means of the engagement member, the first action arm and the second action arm are parallel to each other and can slide relative to each other without separation. Preferably, the cleaning assembly includes two engagement members, so as to prevent the second action arm from swinging when the cleaning assembly works.

[0014] Optionally, the engagement member further includes an extension portion; where the extension portion is located between the sliding portion and the fixing portion, and the extension portion extends in a direction away from a connecting line between a center of the sliding portion and a center of the fixing portion; and a through groove is provided at one end of the extension portion away from the connecting line between the center of the sliding portion and the center of the fixing portion, the through groove is configured for mounting a first guide wheel, and the first guide wheel is configured to roll in a direction perpendicular to an extension direction of the first action arm.

[0015] The first guide wheel reduces the friction between the first cleaning element and the to-be-cleaned surface and the friction between the second cleaning element and the to-be-cleaned surface, and improves the working smoothness of the cleaning assembly.

[0016] Optionally, at least one limiting plate is provided at a position of the opening of the sliding portion, and the at least one limiting plate is configured to prevent the cleaning element from rotating around a central axis of the first action arm or a central axis of the second action arm when the cleaning assembly works.

[0017] The at least one limiting plate at least partially overlaps with a first engagement slot or a second engagement slot, so as to limit the first engagement slot or the second engagement slot, and prevent the first cleaning element in the first engagement slot or the second cleaning element in the second engagement slot from rotating around the first action arm or the second action arm under a reaction force of the to-be-cleaned surface, thereby avoiding weakening the scraping cleanliness. It should be understood that the at least one limiting plate is not an essential feature. If the first action arm or the second action arm has a non-circular (for example, triangle, quadrangle, hexagon or octagonal, etc.) cross section, the contour of the action arm itself limits the cleaning element, so there is no need to provide an additional limiting plate.

[0018] Optionally, the size of the extension portion satisfies that: when the first cleaning element or the second cleaning element is in a natural state, along a direction in which the first cleaning element protrudes from the first engagement slot, a height of the first guide wheel is less than a height of the first cleaning element, or, along a direction in which the second cleaning element protrudes from the second action arm, a height of the first guide wheel is lower than a height of the second cleaning element.

[0019] The size of the extension portion meets the above conditions, so that the first cleaning element and the second cleaning element can be in full contact with the to-be-cleaned surface, the friction between the first cleaning element and the to-be-cleaned surface and the friction between the second cleaning element and the to-be-cleaned surface can be reduced by the first guide wheel, thereby ensuring the smoothness of the cleaning assembly when working.

[0020] Optionally, along the extension direction of the first action arm, a guide groove is provided at one end of the second action arm away from the first action arm; and a second guide wheel is mounted in the guide groove, and a rotation axis of the second guide wheel is perpendicular to the extension direction of the second action arm.

[0021] The second guide wheel is located at one end of the second action arm away from the first action arm, and when the second action arm approaches a ground or a ceiling, the second guide wheel is in contact with the ground or the ceiling, thereby avoiding the friction between the second action arm and the ground or the ceiling, and improving the working smoothness.

[0022] Optionally, the first action arm includes a connecting rod and an operating rod; where a first engagement slot is formed in a side wall of the operating rod, and the first cleaning element is embedded in the first engagement slot; and one end of the connecting rod is hinged to the second end of the connecting arm; and the other end of the connecting rod is connected to one end of the operating rod in a sleeved manner, so that the connecting rod and the operating rod rotate coaxially relative to each other, thereby adjusting a posture of the first cleaning element.

[0023] In this way, the first cleaning element can rotate around the extension axis of the first action arm. Because of the engagement member, the second cleaning element of the second action arm also rotates along with the rotation of the first cleaning element. Therefore, the first action arm includes the connecting rod and the operating rod, and the operating rod and the connecting rod are connected in a sleeved manner to realize the relative rotation of the operating rod and the connecting rod, further driving the second action arm to rotate, and further increasing the degree of freedom of the first cleaning element and the second cleaning element. Such a structure enables the cleaning assembly to clean a second to-be-cleaned surface B which forms an angle greater than or equal to 0 degree and less than or equal to 180 degrees with the panel.

[0024] It should be noted that the angle between the panel and the to-be-cleaned plane is an angle from a surface of the panel to the to-be-cleaned surface.

[0025] In a second aspect, a shower device is further provided according to the present application, which includes a frame, a screen, and the cleaning assembly described above, where a periphery of the screen is at least partially surrounded by the frame, and the base of the cleaning assembly is arranged on a surface of the frame parallel to the screen; when the cleaning assembly is in a non-working state, the first action arm and the second action arm are located within a projection of the frame; and when the cleaning assembly is in a working state, the first action arm and the second action arm rotate around the second end of the connecting arm.

[0026] In this way, when the cleaning assembly is in the non-working state, the cleaning assembly naturally hangs down under the action of gravity and is located within the projection of the frame, without affecting the esthetics of the shower device. When the cleaning assembly works, an operator can hold the first action arm or the second action arm to perform sweeping on the to-be-cleaned surface, and the second action arm extends and retracts along the first action arm to avoid an obstacle (such as a handle, a towel rack, etc.). Optionally, the total length of the first action arm and the second action arm is adjusted based on the size of the to-be-cleaned surface. Preferably, when the second action arm is in a fully extended state, the effective scraping length of the first cleaning element and the second cleaning element is less than or equal to a maximum distance from the second end of the connecting arm to an edge of the to-be-cleaned surface. Preferably, when the second action arm is in a fully retracted state, the effective scraping length of the first cleaning element and the second cleaning element is less than or equal to a minimum distance from the second end of the connecting arm to the edge of the to-be-cleaned surface. For example, when the second action arm is in the fully retracted state, the effective scraping length of the first cleaning element and the second cleaning element is greater than or equal to half of a width of the to-be-cleaned surface.

[0027] The above technical solutions according to the embodiments of the present application have at least the following technical effects.

[0028] With the cleaning assembly, the area covered by a single cleaning is increased, and the single cleaning can cover all of the to-be-cleaned surfaces at the highest, thereby significantly improving the cleaning efficiency. When the cleaning assembly works, the operator only needs to hold the first action arm and / or the second action arm to perform sweeping on the screen being cleaned, which is beneficial for the operator to exert force, and the operator can finish cleaning in a standing posture. Therefore, when the operator uses the cleaning assembly to clean at a low position, the operator does not need to bend down or squat greatly like cleaning with a towel or a conventional wiper, which is ergonomic and is beneficial to improving the cleaning efficiency.

[0029] In the shower device according to the embodiment of the present application, the cleaning assembly described above is mounted on the frame, so that the cleaning assembly is located within the projection range of the frame under the action of gravity when it is in the non-working state, and the cleaning difficulty of the shower device is reduced without affecting the esthetics of the shower device.BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Referring to FIG. 1 and FIG. 2, a cleaning assembly for a shower device is provided according to the present application. FIG. 1 shows a schematic view of a mounting position of the cleaning assembly. As shown in FIG. 1, optionally, the cleaning assembly is mounted on a surface of a frame of a shower room. In FIG. 1, Surface A is a first to-be-cleaned surface, and Surface B is a second to-be-cleaned surface. FIG. 2 shows an optional assembly view of the cleaning assembly. Referring to FIG. 2, the cleaning assembly includes a base 10, a connecting arm 20, a first action arm 30, a second action arm 40, and an engagement member 50.

[0037] Specifically, a first end 202 of the connecting arm 20 is connected to the base 10, and a second end 201 of the connecting arm 20 is hinged to one end of the first action arm 30, so that the first action arm 30 rotates around the second end 201. The second action arm 40 is connected to the first action arm 30, and the second action arm 40 is parallel to an extension axis of the first action arm 30, so that the second action arm 40 can slide relative to the first action arm 30 along the extension axis. A first cleaning element 302 is provided on a side wall of the first action arm 30, and a second cleaning element 402 is provided on a side wall of the second action arm 40. Hereinafter, the first action arm 30 and the second action arm 40 may be collectively referred to as action arms. Hereinafter, the first cleaning element 302 and the second cleaning element 402 are collectively referred to as cleaning elements. According to an embodiment of the present application, preferably, the cleaning element is detachably connected to the action arm, so as to replace the cleaning element based on the cleaning scenario, or the degree of wear or contamination of the cleaning element.

[0038] In some optional embodiments, as shown in FIG. 3, the base 10 includes a panel 101 and a first connecting portion 102. The panel 101 is of a sheet-shaped structure, and the first connecting portion 102 is vertically arranged on one side of the panel 101. A side of the panel 101 away from the first connecting portion 102 is in surface contact with a mounting surface. Optionally, the panel 101 is adhered to the mounting surface. Optionally, the panel 101 may be fixed to the mounting surface by means of screws, riveting, etc. Optionally, one side of the panel 101 away from the first connecting portion 102 is further provided with a snap-fit piece, and the panel 101 is connected to the mounting surface by the snap-fit piece.

[0039] According to an embodiment of the present application, the first connecting portion 102 is configured for mounting the connecting arm 20. In some optional embodiments, one end of the connecting arm 20 is rigidly connected to the first connecting portion 102. For example, the connecting arm 20 is connected to the first connecting portion 102 by an interference fit, snap-fit, a threaded connection, etc. After the connecting arm 20 is connected to the first connecting portion 102, the connecting arm 20 is fixed relative to the first connecting portion 102. For another example, as shown in FIG. 3 and FIG. 4, the first connecting portion 102 is a sheet-shaped insertion plate, and the first end 202 of the connecting arm 20 is provided with a slot. After the sheet-shaped insertion plate is inserted into the slot, a fastener passes through a limiting hole 203 to fasten the sheet-shaped insertion plate.

[0040] In some other optional embodiments, the connecting arm 20 is hinged to the first connecting portion 102. Specifically, the first end 202 of the connecting arm 20 and the first connecting portion 102 form a first hinge. A rotation axis of the first hinge is parallel to the panel 101, so that the connecting arm 20 can rotate around the first end 202 in a plane perpendicular to the panel 101. Exemplarily, as shown in FIG. 5, the connecting arm 20 includes a first end 202 and a second end 201, the first end 202 is configured to form a first hinge with the first connecting portion, and the second end 201 is configured to form a second hinge with the first action arm 30. Optionally, the rotation axis of the first hinge is perpendicular to a rotation axis of the second hinge. Exemplarily, as shown in FIG. 5, the first end 202 includes a first hinged column 2021 and an avoidance hole 2022, and the second end 201 includes a second hinged column 2011. In some optimized embodiments, a limiting device is further provided at a contact position between the first connecting portion 102 and the first end 202, such as a limiting protrusion and a corresponding recess, to limit an angle between the connecting arm 20 and the panel 101. It is not difficult to understand that, the cleaning assembly can achieve a basic cleaning function without the limiting device, because a to-be-cleaned surface itself has a limiting effect on the cleaning assembly.

[0041] In some exemplary embodiments, each of the first action arm 30 and the second action arm 40 is preferably of a rod-shaped structure or a strip-shaped structure. Along a direction perpendicular to an extension direction of the rod-shaped structure or the strip-shaped structure, the cross-sectional shape of the rod-shaped or strip-shaped structure may be circular, quadrilateral, hexagonal or octagonal, etc. It should be understood that, the rod-shaped or strip-shaped structure is not limited to extending along a straight line, and is not limited to having a circular or polygonal cross-sectional shape, and the rod-shaped or strip-shaped structure may be in any shape that is convenient for storage or convenient for an operator to hold.

[0042] Optionally, any end of the first action arm 30, i.e. a third end 303, forms the second hinge with the second end 201 of the connecting arm 20. The rotation axis of the second hinge is perpendicular to the rotation axis of the first hinge, and the rotation axis of the second hinge is perpendicular to a plane where the first action arm 30 is located. By means of the second hinge, the first action arm 30 rotates around the second end 202 and drives the second action arm 40 to rotate synchronously, thereby cleaning the to-be-cleaned surface. The first hinge cooperates with the second hinge, so that the first to-be-cleaned surface A, which forms an included angle α greater than 0 degree and less than or equal to 180 degrees with the panel, can be cleaned. In this way, the flexibility of the cleaning assembly according to the present application is improved, so that the cleaning assembly can be applied to more types of shower rooms, such as rectangular shower rooms or diamond-shaped shower rooms.

[0043] More advantageously, as shown in FIG. 6, the first action arm 30 includes a connecting rod 31 and an operating rod 32. The connecting rod 31 is connected to the operating rod 32 in a sleeved manner, so that the connecting rod 31 and the operating rod 32 can rotate relative to each other around a common central axis of the connecting rod 31 and the operating rod 32. One end of the connecting rod 31 away from a center of the operating rod 32 is referred to as a third end 303, and the third end 303 is configured to form a second hinge with the second end 201 of the connecting arm 20. The first cleaning element may be arranged on any side of the operating rod, and the operating rod and the second action arm are connected to each other and can slide axially relative to each other. When the connecting rod remains stationary, the first cleaning element can rotate around the central axis of the connecting rod by rotating the operating rod. Preferably, when the operating rod is rotated, the second action arm connected to the first operating rod rotates accordingly. Correspondingly, the orientation of the second cleaning element also changes. In this way, the orientation or posture of the cleaning element can be adjusted. Such a mechanism can not only adjust an angle between the cleaning element and a cleaning surface based on requirements of different cleaning tasks, but also clean the second to-be-cleaned surface B. On this basis, in combination with the first hinge, two to-be-cleaned surfaces A and B that are opposite can be cleaned, and the flexibility of the cleaning assembly is further improved. For example, the sleeved connection between the connecting rod 31 and the operating rod 32 may be realized by a threaded connection or a snap-fit connection, or may be limited by a limiter 33. It is not difficult to understand that, by means of conventional technical means in the art, the connecting rod 31 and the operating rod 32 can rotate coaxially with each other, and the axial movement of the connecting rod 31 and the operating rod 32 can be avoided.

[0044] It should be noted that, the connection between the first action arm 30 and the second action arm 40 can be realized by means of any technical means understood by those skilled in the art, as long as the first action arm 30 and the second action arm 40 can slide relative to each other in the axial direction. For example, as shown in FIG. 7, the first action arm 30 and the second action arm 40 are connected in a sleeved manner. For another example, the first action arm 30 is connected to the second action arm 40 by the engagement member 50. The axial direction herein refers to the extension axis (also referred to as a length axis) of the first action arm 30 or the second action arm 40. Exemplarily, as shown in FIG. 7, each of the first action arm 30 and the second action arm 40 is a square profile, and the first action arm 30 and the second action arm 40 are connected in a sleeved manner. Optionally, the cleaning assembly further includes an engagement member 50, which is configured to prevent the second action arm 40 from swinging.

[0045] It is not difficult to understand that, the cleaning element includes a wiper strip, a brush, a roller brush, or other flexible cleaning tools to adapt to different cleaning scenarios. It should be understood that, the cleaning element may be mounted on one side of the action arm by any technical means understood by those skilled in the art. For example, the cleaning element may be adhered to a surface of one side of the action arm. For another example, an engagement slot may be formed in a surface of one side of the action arm by directly slotting in the surface of one side of the action arm, integrally forming, pasting, or the like, so that at least part of the cleaning element is embedded into the engagement slot. For another example, clamping pieces are fixed radially at two ends of the action arm, and the cleaning element (for example, a wiper strip or a rolling brush) is embedded between the clamping pieces. It is not difficult to understand that, when the first action arm and the second action arm are connected in a sleeved manner, the cleaning elements of the two action arms avoid each other in a circumferential direction of the action arms, so as to prevent the corresponding cleaning elements from interfering with each other when the first action arm 30 and the second action arm 40 slide relative to each other in the axial direction.

[0046] In an optional embodiment, as shown in FIG. 7 to FIG. 9, a first engagement slot 301 is formed on one side of the first action arm 30, and the first cleaning element 302 is embedded in the first engagement slot 301. Along the direction perpendicular to the extension direction of the first action arm 30, the first cleaning element 302 at least partially protrudes from the first engagement slot 301. FIG. 8 shows the structures of the first cleaning element 302 and the first clamping slot 301 at different viewing angles when they are engaged with each other. FIG. 9 shows the structures of the first cleaning element 302 and the first clamping slot 301 at different viewing angles when they are disassembled.

[0047] According to some other optional embodiments, as shown in FIG. 10 and FIG. 11, a second engagement slot 401 is formed on one side of the second action arm 40, and the second cleaning element 402 is embedded in the second engagement slot 401. Along the direction perpendicular to the extension direction of the second action arm 40, the second cleaning element 402 at least partially protrudes from the second engagement slot 401. FIG. 10 shows the structures of the second cleaning element 402 and the second engagement slot 401 at different viewing angles when they are engaged with each other. FIG. 11 shows the structures of the second cleaning element 402 and the second engagement slot 401 at different viewing angles when they are disassembled. Exemplarily, the cleaning element illustrated in FIG. 6 to FIG. 11 is a wiper strip, and a wiper portion of the wiper strip includes sheets radially distributed. Optionally, the wiper strip is made of a flexible material such as rubber, silica gel, or the like.

[0048] According to some optional embodiments of the present application, as shown in FIG. 10, a guide groove 403 is provided at one end of the second action arm 40 for mounting a second guide wheel 802. A rotation axis of the second guide wheel 802 is perpendicular to the extension axis of the second action arm. Moreover, when the cleaning assembly works, the second guide wheel 802 is perpendicular to a to-be-cleaned surface. When one end of the second action arm 40 away from the first action arm 30 approaches a ground or ceiling, the second guide wheel 802 can reduce friction between the second action arm 40 and the ground or the ceiling, thereby increasing the smoothness of the operation of the cleaning assembly.

[0049] In some other optional embodiments, as shown in FIG. 2, FIG. 12, FIG. 13 and FIG. 14, the cleaning assembly further includes an engagement member 50. The first action arm 30 is connected to the second action arm 40 by the engagement member 50, so that the second action arm 40 can slide along the extension axis of the first action arm 30. Referring to FIG. 12, the engagement member 50 includes a sliding portion 501 and a fixing portion 502 arranged in parallel. The sliding portion 501 is a ring with an opening, and the fixing portion 502 is of a cover-shaped structure. As shown in FIG. 2 and FIG. 14, the sliding portion 501 is engaged with a main body of the first action arm 30 or a main body of the second action arm 40. The fixing portion 502 is sleeved on an end of the first action arm 30 or an end of the second action arm 40. In this way, the first action arm is engaged with the second action arm. As shown in FIG. 2, FIG. 5 and FIG. 10, one end (i.e., a fourth end 304) of the first action arm 30 away from the connecting arm 20 is matched with the shape of the fixing portion 502. The fourth end 304 is provided with a threaded hole, and a through-hole is provided in a bottom portion of the fixing portion 502. When the engagement member 50 is engaged with the first action arm, the threaded hole is aligned with the through-hole, and the fixing portion is fixedly connected to the first action arm by a bolt. As shown in FIG. 2 and FIG. 10, one end of the second action arm 40 close to the first action arm 30 is provided with a threaded hole, and the end is matched with the shape of the fixing portion 502, so that the second action arm 40 can be fixedly connected to the fixing portion 502 by threaded connection. Optionally, the cleaning assembly includes two engagement members. As shown in FIG. 2, one of the two engagement members is fixedly connected to the fourth end 304 of the first action arm 30, and the other of the two engagement members is fixedly connected to one end of the second action arm 40 close to the first action arm 30. In this way, the second action arm 40 can be prevented from swinging when the second action arm 40 rotates along with the first action arm 30. Optionally, the axial length of the sliding portion 501 is increased, which can improve the stability of the first action arm and the second action arm when the first action arm and the second action arm slide relative to each other in the axial direction. Therefore, only one engagement member 50 is required to prevent the second action arm from swinging when the first action arm and the second action arm slide relative to each other in the axial direction.

[0050] In some preferred embodiments, as shown in FIG. 12, the engagement member 50 further includes an extension portion 503. The extension portion 503 is located between the sliding portion 501 and the fixing portion 502, and the extension portion 503 extends in a direction away from a connecting line between a center of the sliding portion 501 and a center of the fixing portion 502. One end of the extension portion 503 away from the connecting line between the center of the sliding portion 501 and the center of the fixing portion 502 is provided with a through groove 504, the through groove 504 is configured for mounting a first guide wheel 801, and the first guide wheel 801 rolls in a direction perpendicular to the extension direction of the first action arm 30. That is, the first guide wheel 801 can roll on the to-be-cleaned surface. It is not difficult to understand that, a depth of the through groove 504 satisfies that the first guide wheel 801 at least partially protrudes from a top of the through groove 504 or an end of the extension portion 503.

[0051] Further, the size of the extension portion 503 satisfies that: when the first cleaning element 302 or the second cleaning element 402 is in a natural state, a height of the first guide wheel 801 is smaller than a height of the first cleaning element 302 along a direction in which the first cleaning element 302 protrudes from the first action arm 30, or, a height of the second guide wheel 802 is lower than a height of the second cleaning element 402 along a direction in which the second cleaning element 402 protrudes from the second action arm 40. In this way, the friction between the cleaning assembly and the to-be-cleaned surface can be reduced on the premise of ensuring that the cleaning element is in contact with the to-be-cleaned surface, thereby improving the smoothness of the cleaning assembly during operation.

[0052] In some other optional embodiments, at least one limiting plate 505 is provided at a position of the opening of the sliding portion 501. The at least one limiting plate 505 is configured to prevent the first cleaning element 302 or the second cleaning element 402 from rotating around a central axis of the first action arm 30 or a central axis of the second action arm 40 when the cleaning assembly works. For example, as shown in FIG. 12 and FIG. 13, the limiting plate 505 and the extension portion 503 form a limiting slot.

[0053] In another aspect, a shower device is further provided according to an embodiment of the present application. As shown in FIG. 1, the shower device includes a frame, a screen, and the cleaning assembly described above. A periphery of the screen is at least partially surrounded by the frame. The base 10 of the cleaning assembly is arranged on a surface of the frame parallel to the screen. The frame supports the screen.

[0054] When the cleaning assembly is in a non-working state, the first action arm 30 and the second action arm 40 are located within a projection range of the frame. When the cleaning assembly is in a working state, the first action arm 30 and the second action arm 40 rotate around the second end of the connecting arm 20.

[0055] FIG. 15(a), FIG. 15(c), FIG. 15(d), and FIG. 15(e) sequentially show postures of the cleaning assembly according to the present application from the non-working state to a first extreme position.

[0056] In summary, the cleaning assembly improves the area covered by a single cleaning, and the single cleaning can cover all of the to-be-cleaned surfaces at most, which significantly improves the cleaning efficiency. When the cleaning assembly works, the operator only needs to hold the first action arm and / or the second action arm to sweep on the screen being cleaned, which is convenient for the operator to exert force, and the operator can finish cleaning in a standing posture. Therefore, when the operator uses the cleaning assembly to perform the cleaning at a low position, the operator does not need to bend down or squat significantly like using a towel or a conventional wiper, which is more ergonomic and is beneficial to improving the cleaning efficiency.

[0057] In the shower device according to the embodiment of the present application, the cleaning assembly described above is mounted on the frame, so that the cleaning assembly is located within the projection range of the frame under the action of gravity when it is in the non-working state, and the cleaning difficulty of the shower device is reduced without affecting the esthetics of the shower device.

[0058] The description of the above embodiments is only used to facilitate understanding the method and core idea of the present application. It should be noted that, several improvements and modifications may be made to the present application by those skilled in the art without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.

FIELD

[0001] The present application relates to the technical field of shower device, and in particular, to a cleaning assembly and a shower device including the same.BACKGROUND

[0002] With the development of the home industry, more and more users choose shower rooms to separate dry and wet spaces.

[0003] In the conventional technology, a shower room limits overflow and sputtered liquid during showering to a specified space. The sputtered liquid adheres to and remains on a screen of the shower room to form water stains, which may easily breed bacteria over time, thereby affecting hygiene and aesthetics. Moreover, the liquid sputtered during showering includes impurities such as bath lotion and grease. These impurities further increase the stubbornness of water stains. The conventional towels and cleaning assemblies have small single cleaning areas and limited cleaning efficiency, so it is time-consuming and laborious to clean the screen of the shower room by using the conventional towels and cleaning assemblies.

[0004] Therefore, there is an urgent need for a cleaning assembly suitable for the shower room.SUMMARY

[0005] In view of this, the technical problem to be solved by the present application is to provide a cleaning assembly with high cleaning efficiency.

[0006] In one aspect, a cleaning assembly is provided according to an embodiment of the present application, which includes a base, a connecting arm, a first action arm and a second action arm, where a first end of the connecting arm is connected to the base; and a second end of the connecting arm is hinged to one end of the first action arm, to allow the first action arm to rotate around the second end; the second action arm is connected to the first action arm, and the second action arm is parallel to an extension axis of the first action arm, so as to allow the second action arm to slide along the extension axis relative to the first action arm; and a first cleaning element is provided on one side of the first action arm, and a second cleaning element is provided on one side of the second action arm.

[0007] According to the present application, the first action arm is hinged to the second end of the connecting arm through the above structure, so that the first action arm rotates around the second end in a plane where the connecting arm is located, and the second action arm connected to the first action arm is driven to rotate synchronously. When the first action arm rotates, the first cleaning element on the first action arm scrapes off water stains, and similarly, the second cleaning element on the second action arm also scrapes off water stains. In particular, the first action arm and the second action arm are connected to each other and can slide relative to each other axially, and an effective cleaning radius can be adjusted according to the dimension of a to-be-cleaned surface. For example, components such as a towel bar, a handle, a hinge or the like may be mounted on a screen of a shower room, and these existing components on the screen can be avoided by adjusting the length of an overlapping portion of the first action arm and the second action arm in the axial direction, so that cleaning is flexible. It should be noted that, the connection between the first end of the connecting arm and the base may be a detachable connection (for example, a threaded connection or a snap connection), or may be a fixed connection (for example, a connection by welding or riveting, etc.), or may be a hinged connection.

[0008] Optionally, the base includes a panel and a first connecting portion, and the first connecting portion is vertically arranged on one side of the panel.

[0009] According to an embodiment of the present application, the panel is configured for fixing the cleaning assembly, and may be pasted on a mounting surface or may be fixed to the mounting surface by a screw or a rivet. Generally, the mounting surface is flat, which may be a wall surface, a screen of a shower room, or a frame of a shower room. The first connecting portion may be a connecting rod, an insertion plate, a threaded hole, a hinge portion, or the like.

[0010] Optionally, the first end of the connecting arm and the first connecting portion form a first hinge; and a rotation axis of the first hinge is parallel to the panel, to allow the connecting arm to rotate in a first working plane perpendicular to the panel.

[0011] In this way, with the first hinge, the connecting arm can rotate in the plane perpendicular to the panel, and thereby driving the first action arm and the second action arm to rotate in the plane perpendicular to the panel. Therefore, a working surface of the first action arm and the second action arm may be a plane where the panel is located, or may be any plane that forms an angle with the panel. The cleaning assembly can clean a first to-be-cleaned surface A which forms an angle greater than or equal to 0 degree and less than or equal to 180 degrees with the panel, thereby increasing the degree of freedom of the cleaning assembly and realizing flexible deployment of the cleaning assembly.

[0012] Optionally, the cleaning assembly further includes an engagement member, and the engagement member includes a sliding portion and a fixing portion that are arranged in parallel with each other; where the sliding portion is a ring with an opening, and the fixing portion is of a cover-shaped structure; the sliding portion is engaged with a main body of the first action arm or a main body of the second action arm; and the fixing portion is connected to an end of the second action arm or an end of the first action arm.

[0013] According to the embodiment of the present application, the first action arm or the second action arm is engaged into an inner side of the sliding portion through the opening of the ring, so that the engagement member can slide along the extension axis of the first action arm or the second action arm. In the embodiment of the present application, the fixing portion is of a cover-shaped structure, and the cover-shaped structure is -connected in a sleeved manner to the end of the second action arm or the end of the first action arm, thereby preventing the axial movement of the second action arm or the first action arm. By means of the engagement member, the first action arm and the second action arm are parallel to each other and can slide relative to each other without separation. Preferably, the cleaning assembly includes two engagement members, so as to prevent the second action arm from swinging when the cleaning assembly works.

[0014] Optionally, the engagement member further includes an extension portion; where the extension portion is located between the sliding portion and the fixing portion, and the extension portion extends in a direction away from a connecting line between a center of the sliding portion and a center of the fixing portion; and a through groove is provided at one end of the extension portion away from the connecting line between the center of the sliding portion and the center of the fixing portion, the through groove is configured for mounting a first guide wheel, and the first guide wheel is configured to roll in a direction perpendicular to an extension direction of the first action arm.

[0015] The first guide wheel reduces the friction between the first cleaning element and the to-be-cleaned surface and the friction between the second cleaning element and the to-be-cleaned surface, and improves the working smoothness of the cleaning assembly.

[0016] Optionally, at least one limiting plate is provided at a position of the opening of the sliding portion, and the at least one limiting plate is configured to prevent the cleaning element from rotating around a central axis of the first action arm or a central axis of the second action arm when the cleaning assembly works.

[0017] The at least one limiting plate at least partially overlaps with a first engagement slot or a second engagement slot, so as to limit the first engagement slot or the second engagement slot, and prevent the first cleaning element in the first engagement slot or the second cleaning element in the second engagement slot from rotating around the first action arm or the second action arm under a reaction force of the to-be-cleaned surface, thereby avoiding weakening the scraping cleanliness. It should be understood that the at least one limiting plate is not an essential feature. If the first action arm or the second action arm has a non-circular (for example, triangle, quadrangle, hexagon or octagonal, etc.) cross section, the contour of the action arm itself limits the cleaning element, so there is no need to provide an additional limiting plate.

[0018] Optionally, the size of the extension portion satisfies that: when the first cleaning element or the second cleaning element is in a natural state, along a direction in which the first cleaning element protrudes from the first engagement slot, a height of the first guide wheel is less than a height of the first cleaning element, or, along a direction in which the second cleaning element protrudes from the second action arm, a height of the first guide wheel is lower than a height of the second cleaning element.

[0019] The size of the extension portion meets the above conditions, so that the first cleaning element and the second cleaning element can be in full contact with the to-be-cleaned surface, the friction between the first cleaning element and the to-be-cleaned surface and the friction between the second cleaning element and the to-be-cleaned surface can be reduced by the first guide wheel, thereby ensuring the smoothness of the cleaning assembly when working.

[0020] Optionally, along the extension direction of the first action arm, a guide groove is provided at one end of the second action arm away from the first action arm; and a second guide wheel is mounted in the guide groove, and a rotation axis of the second guide wheel is perpendicular to the extension direction of the second action arm.

[0021] The second guide wheel is located at one end of the second action arm away from the first action arm, and when the second action arm approaches a ground or a ceiling, the second guide wheel is in contact with the ground or the ceiling, thereby avoiding the friction between the second action arm and the ground or the ceiling, and improving the working smoothness.

[0022] Optionally, the first action arm includes a connecting rod and an operating rod; where a first engagement slot is formed in a side wall of the operating rod, and the first cleaning element is embedded in the first engagement slot; and one end of the connecting rod is hinged to the second end of the connecting arm; and the other end of the connecting rod is connected to one end of the operating rod in a sleeved manner, so that the connecting rod and the operating rod rotate coaxially relative to each other, thereby adjusting a posture of the first cleaning element.

[0023] In this way, the first cleaning element can rotate around the extension axis of the first action arm. Because of the engagement member, the second cleaning element of the second action arm also rotates along with the rotation of the first cleaning element. Therefore, the first action arm includes the connecting rod and the operating rod, and the operating rod and the connecting rod are connected in a sleeved manner to realize the relative rotation of the operating rod and the connecting rod, further driving the second action arm to rotate, and further increasing the degree of freedom of the first cleaning element and the second cleaning element. Such a structure enables the cleaning assembly to clean a second to-be-cleaned surface B which forms an angle greater than or equal to 0 degree and less than or equal to 180 degrees with the panel.

[0024] It should be noted that the angle between the panel and the to-be-cleaned plane is an angle from a surface of the panel to the to-be-cleaned surface.

[0025] In a second aspect, a shower device is further provided according to the present application, which includes a frame, a screen, and the cleaning assembly described above, where a periphery of the screen is at least partially surrounded by the frame, and the base of the cleaning assembly is arranged on a surface of the frame parallel to the screen; when the cleaning assembly is in a non-working state, the first action arm and the second action arm are located within a projection of the frame; and when the cleaning assembly is in a working state, the first action arm and the second action arm rotate around the second end of the connecting arm.

[0026] In this way, when the cleaning assembly is in the non-working state, the cleaning assembly naturally hangs down under the action of gravity and is located within the projection of the frame, without affecting the esthetics of the shower device. When the cleaning assembly works, an operator can hold the first action arm or the second action arm to perform sweeping on the to-be-cleaned surface, and the second action arm extends and retracts along the first action arm to avoid an obstacle (such as a handle, a towel rack, etc.). Optionally, the total length of the first action arm and the second action arm is adjusted based on the size of the to-be-cleaned surface. Preferably, when the second action arm is in a fully extended state, the effective scraping length of the first cleaning element and the second cleaning element is less than or equal to a maximum distance from the second end of the connecting arm to an edge of the to-be-cleaned surface. Preferably, when the second action arm is in a fully retracted state, the effective scraping length of the first cleaning element and the second cleaning element is less than or equal to a minimum distance from the second end of the connecting arm to the edge of the to-be-cleaned surface. For example, when the second action arm is in the fully retracted state, the effective scraping length of the first cleaning element and the second cleaning element is greater than or equal to half of a width of the to-be-cleaned surface.

[0027] The above technical solutions according to the embodiments of the present application have at least the following technical effects.

[0028] With the cleaning assembly, the area covered by a single cleaning is increased, and the single cleaning can cover all of the to-be-cleaned surfaces at the highest, thereby significantly improving the cleaning efficiency. When the cleaning assembly works, the operator only needs to hold the first action arm and / or the second action arm to perform sweeping on the screen being cleaned, which is beneficial for the operator to exert force, and the operator can finish cleaning in a standing posture. Therefore, when the operator uses the cleaning assembly to clean at a low position, the operator does not need to bend down or squat greatly like cleaning with a towel or a conventional wiper, which is ergonomic and is beneficial to improving the cleaning efficiency.

[0029] In the shower device according to the embodiment of the present application, the cleaning assembly described above is mounted on the frame, so that the cleaning assembly is located within the projection range of the frame under the action of gravity when it is in the non-working state, and the cleaning difficulty of the shower device is reduced without affecting the esthetics of the shower device.BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following description is merely exemplary in nature and is not intended to limit the present disclosure and the application or use thereof. It should be understood that the corresponding reference numerals in the drawings always indicate the same or corresponding components and features throughout.

[0033] Exemplary embodiments are provided so that the disclosure of the present application is sufficient and the scope is fully conveyed to those skilled in the art. Many specific details, such as examples of specific components, devices, and methods, are set forth to provide a comprehensive understanding of the embodiments of the present application.

[0036] Referring to FIG. 1 and FIG. 2, a cleaning assembly for a shower device is provided according to the present application. FIG. 1 shows a schematic view of a mounting position of the cleaning assembly. As shown in FIG. 1, optionally, the cleaning assembly is mounted on a surface of a frame of a shower room. In FIG. 1, Surface A is a first to-be-cleaned surface, and Surface B is a second to-be-cleaned surface. FIG. 2 shows an optional assembly view of the cleaning assembly. Referring to FIG. 2, the cleaning assembly includes a base 10, a connecting arm 20, a first action arm 30, a second action arm 40, and an engagement member 50.

[0037] Specifically, a first end 202 of the connecting arm 20 is connected to the base 10, and a second end 201 of the connecting arm 20 is hinged to one end of the first action arm 30, so that the first action arm 30 rotates around the second end 201. The second action arm 40 is connected to the first action arm 30, and the second action arm 40 is parallel to an extension axis of the first action arm 30, so that the second action arm 40 can slide relative to the first action arm 30 along the extension axis. A first cleaning element 302 is provided on a side wall of the first action arm 30, and a second cleaning element 402 is provided on a side wall of the second action arm 40. Hereinafter, the first action arm 30 and the second action arm 40 may be collectively referred to as action arms. Hereinafter, the first cleaning element 302 and the second cleaning element 402 are collectively referred to as cleaning elements. According to an embodiment of the present application, preferably, the cleaning element is detachably connected to the action arm, so as to replace the cleaning element based on the cleaning scenario, or the degree of wear or contamination of the cleaning element.

[0038] In some optional embodiments, as shown in FIG. 3, the base 10 includes a panel 101 and a first connecting portion 102. The panel 101 is of a sheet-shaped structure, and the first connecting portion 102 is vertically arranged on one side of the panel 101. A side of the panel 101 away from the first connecting portion 102 is in surface contact with a mounting surface. Optionally, the panel 101 is adhered to the mounting surface. Optionally, the panel 101 may be fixed to the mounting surface by means of screws, riveting, etc. Optionally, one side of the panel 101 away from the first connecting portion 102 is further provided with a snap-fit piece, and the panel 101 is connected to the mounting surface by the snap-fit piece.

[0039] According to an embodiment of the present application, the first connecting portion 102 is configured for mounting the connecting arm 20. In some optional embodiments, one end of the connecting arm 20 is rigidly connected to the first connecting portion 102. For example, the connecting arm 20 is connected to the first connecting portion 102 by an interference fit, snap-fit, a threaded connection, etc. After the connecting arm 20 is connected to the first connecting portion 102, the connecting arm 20 is fixed relative to the first connecting portion 102. For another example, as shown in FIG. 3 and FIG. 4, the first connecting portion 102 is a sheet-shaped insertion plate, and the first end 202 of the connecting arm 20 is provided with a slot. After the sheet-shaped insertion plate is inserted into the slot, a fastener passes through a limiting hole 203 to fasten the sheet-shaped insertion plate.

[0040] In some other optional embodiments, the connecting arm 20 is hinged to the first connecting portion 102. Specifically, the first end 202 of the connecting arm 20 and the first connecting portion 102 form a first hinge. A rotation axis of the first hinge is parallel to the panel 101, so that the connecting arm 20 can rotate around the first end 202 in a plane perpendicular to the panel 101. Exemplarily, as shown in FIG. 5, the connecting arm 20 includes a first end 202 and a second end 201, the first end 202 is configured to form a first hinge with the first connecting portion, and the second end 201 is configured to form a second hinge with the first action arm 30. Optionally, the rotation axis of the first hinge is perpendicular to a rotation axis of the second hinge. Exemplarily, as shown in FIG. 5, the first end 202 includes a first hinged column 2021 and an avoidance hole 2022, and the second end 201 includes a second hinged column 2011. In some optimized embodiments, a limiting device is further provided at a contact position between the first connecting portion 102 and the first end 202, such as a limiting protrusion and a corresponding recess, to limit an angle between the connecting arm 20 and the panel 101. It is not difficult to understand that, the cleaning assembly can achieve a basic cleaning function without the limiting device, because a to-be-cleaned surface itself has a limiting effect on the cleaning assembly.

[0041] In some exemplary embodiments, each of the first action arm 30 and the second action arm 40 is preferably of a rod-shaped structure or a strip-shaped structure. Along a direction perpendicular to an extension direction of the rod-shaped structure or the strip-shaped structure, the cross-sectional shape of the rod-shaped or strip-shaped structure may be circular, quadrilateral, hexagonal or octagonal, etc. It should be understood that, the rod-shaped or strip-shaped structure is not limited to extending along a straight line, and is not limited to having a circular or polygonal cross-sectional shape, and the rod-shaped or strip-shaped structure may be in any shape that is convenient for storage or convenient for an operator to hold.

[0042] Optionally, any end of the first action arm 30, i.e. a third end 303, forms the second hinge with the second end 201 of the connecting arm 20. The rotation axis of the second hinge is perpendicular to the rotation axis of the first hinge, and the rotation axis of the second hinge is perpendicular to a plane where the first action arm 30 is located. By means of the second hinge, the first action arm 30 rotates around the second end 202 and drives the second action arm 40 to rotate synchronously, thereby cleaning the to-be-cleaned surface. The first hinge cooperates with the second hinge, so that the first to-be-cleaned surface A, which forms an included angle α greater than 0 degree and less than or equal to 180 degrees with the panel, can be cleaned. In this way, the flexibility of the cleaning assembly according to the present application is improved, so that the cleaning assembly can be applied to more types of shower rooms, such as rectangular shower rooms or diamond-shaped shower rooms.

[0043] More advantageously, as shown in FIG. 6, the first action arm 30 includes a connecting rod 31 and an operating rod 32. The connecting rod 31 is connected to the operating rod 32 in a sleeved manner, so that the connecting rod 31 and the operating rod 32 can rotate relative to each other around a common central axis of the connecting rod 31 and the operating rod 32. One end of the connecting rod 31 away from a center of the operating rod 32 is referred to as a third end 303, and the third end 303 is configured to form a second hinge with the second end 201 of the connecting arm 20. The first cleaning element may be arranged on any side of the operating rod, and the operating rod and the second action arm are connected to each other and can slide axially relative to each other. When the connecting rod remains stationary, the first cleaning element can rotate around the central axis of the connecting rod by rotating the operating rod. Preferably, when the operating rod is rotated, the second action arm connected to the first operating rod rotates accordingly. Correspondingly, the orientation of the second cleaning element also changes. In this way, the orientation or posture of the cleaning element can be adjusted. Such a mechanism can not only adjust an angle between the cleaning element and a cleaning surface based on requirements of different cleaning tasks, but also clean the second to-be-cleaned surface B. On this basis, in combination with the first hinge, two to-be-cleaned surfaces A and B that are opposite can be cleaned, and the flexibility of the cleaning assembly is further improved. For example, the sleeved connection between the connecting rod 31 and the operating rod 32 may be realized by a threaded connection or a snap-fit connection, or may be limited by a limiter 33. It is not difficult to understand that, by means of conventional technical means in the art, the connecting rod 31 and the operating rod 32 can rotate coaxially with each other, and the axial movement of the connecting rod 31 and the operating rod 32 can be avoided.

[0044] It should be noted that, the connection between the first action arm 30 and the second action arm 40 can be realized by means of any technical means understood by those skilled in the art, as long as the first action arm 30 and the second action arm 40 can slide relative to each other in the axial direction. For example, as shown in FIG. 7, the first action arm 30 and the second action arm 40 are connected in a sleeved manner. For another example, the first action arm 30 is connected to the second action arm 40 by the engagement member 50. The axial direction herein refers to the extension axis (also referred to as a length axis) of the first action arm 30 or the second action arm 40. Exemplarily, as shown in FIG. 7, each of the first action arm 30 and the second action arm 40 is a square profile, and the first action arm 30 and the second action arm 40 are connected in a sleeved manner. Optionally, the cleaning assembly further includes an engagement member 50, which is configured to prevent the second action arm 40 from swinging.

[0045] It is not difficult to understand that, the cleaning element includes a wiper strip, a brush, a roller brush, or other flexible cleaning tools to adapt to different cleaning scenarios. It should be understood that, the cleaning element may be mounted on one side of the action arm by any technical means understood by those skilled in the art. For example, the cleaning element may be adhered to a surface of one side of the action arm. For another example, an engagement slot may be formed in a surface of one side of the action arm by directly slotting in the surface of one side of the action arm, integrally forming, pasting, or the like, so that at least part of the cleaning element is embedded into the engagement slot. For another example, clamping pieces are fixed radially at two ends of the action arm, and the cleaning element (for example, a wiper strip or a rolling brush) is embedded between the clamping pieces. It is not difficult to understand that, when the first action arm and the second action arm are connected in a sleeved manner, the cleaning elements of the two action arms avoid each other in a circumferential direction of the action arms, so as to prevent the corresponding cleaning elements from interfering with each other when the first action arm 30 and the second action arm 40 slide relative to each other in the axial direction.

[0046] In an optional embodiment, as shown in FIG. 7 to FIG. 9, a first engagement slot 301 is formed on one side of the first action arm 30, and the first cleaning element 302 is embedded in the first engagement slot 301. Along the direction perpendicular to the extension direction of the first action arm 30, the first cleaning element 302 at least partially protrudes from the first engagement slot 301. FIG. 8 shows the structures of the first cleaning element 302 and the first clamping slot 301 at different viewing angles when they are engaged with each other. FIG. 9 shows the structures of the first cleaning element 302 and the first clamping slot 301 at different viewing angles when they are disassembled.

[0047] According to some other optional embodiments, as shown in FIG. 10 and FIG. 11, a second engagement slot 401 is formed on one side of the second action arm 40, and the second cleaning element 402 is embedded in the second engagement slot 401. Along the direction perpendicular to the extension direction of the second action arm 40, the second cleaning element 402 at least partially protrudes from the second engagement slot 401. FIG. 10 shows the structures of the second cleaning element 402 and the second engagement slot 401 at different viewing angles when they are engaged with each other. FIG. 11 shows the structures of the second cleaning element 402 and the second engagement slot 401 at different viewing angles when they are disassembled. Exemplarily, the cleaning element illustrated in FIG. 6 to FIG. 11 is a wiper strip, and a wiper portion of the wiper strip includes sheets radially distributed. Optionally, the wiper strip is made of a flexible material such as rubber, silica gel, or the like.

[0048] According to some optional embodiments of the present application, as shown in FIG. 10, a guide groove 403 is provided at one end of the second action arm 40 for mounting a second guide wheel 802. A rotation axis of the second guide wheel 802 is perpendicular to the extension axis of the second action arm. Moreover, when the cleaning assembly works, the second guide wheel 802 is perpendicular to a to-be-cleaned surface. When one end of the second action arm 40 away from the first action arm 30 approaches a ground or ceiling, the second guide wheel 802 can reduce friction between the second action arm 40 and the ground or the ceiling, thereby increasing the smoothness of the operation of the cleaning assembly.

[0049] In some other optional embodiments, as shown in FIG. 2, FIG. 12, FIG. 13 and FIG. 14, the cleaning assembly further includes an engagement member 50. The first action arm 30 is connected to the second action arm 40 by the engagement member 50, so that the second action arm 40 can slide along the extension axis of the first action arm 30. Referring to FIG. 12, the engagement member 50 includes a sliding portion 501 and a fixing portion 502 arranged in parallel. The sliding portion 501 is a ring with an opening, and the fixing portion 502 is of a cover-shaped structure. As shown in FIG. 2 and FIG. 14, the sliding portion 501 is engaged with a main body of the first action arm 30 or a main body of the second action arm 40. The fixing portion 502 is sleeved on an end of the first action arm 30 or an end of the second action arm 40. In this way, the first action arm is engaged with the second action arm. As shown in FIG. 2, FIG. 5 and FIG. 10, one end (i.e., a fourth end 304) of the first action arm 30 away from the connecting arm 20 is matched with the shape of the fixing portion 502. The fourth end 304 is provided with a threaded hole, and a through-hole is provided in a bottom portion of the fixing portion 502. When the engagement member 50 is engaged with the first action arm, the threaded hole is aligned with the through-hole, and the fixing portion is fixedly connected to the first action arm by a bolt. As shown in FIG. 2 and FIG. 10, one end of the second action arm 40 close to the first action arm 30 is provided with a threaded hole, and the end is matched with the shape of the fixing portion 502, so that the second action arm 40 can be fixedly connected to the fixing portion 502 by threaded connection. Optionally, the cleaning assembly includes two engagement members. As shown in FIG. 2, one of the two engagement members is fixedly connected to the fourth end 304 of the first action arm 30, and the other of the two engagement members is fixedly connected to one end of the second action arm 40 close to the first action arm 30. In this way, the second action arm 40 can be prevented from swinging when the second action arm 40 rotates along with the first action arm 30. Optionally, the axial length of the sliding portion 501 is increased, which can improve the stability of the first action arm and the second action arm when the first action arm and the second action arm slide relative to each other in the axial direction. Therefore, only one engagement member 50 is required to prevent the second action arm from swinging when the first action arm and the second action arm slide relative to each other in the axial direction.

[0050] In some preferred embodiments, as shown in FIG. 12, the engagement member 50 further includes an extension portion 503. The extension portion 503 is located between the sliding portion 501 and the fixing portion 502, and the extension portion 503 extends in a direction away from a connecting line between a center of the sliding portion 501 and a center of the fixing portion 502. One end of the extension portion 503 away from the connecting line between the center of the sliding portion 501 and the center of the fixing portion 502 is provided with a through groove 504, the through groove 504 is configured for mounting a first guide wheel 801, and the first guide wheel 801 rolls in a direction perpendicular to the extension direction of the first action arm 30. That is, the first guide wheel 801 can roll on the to-be-cleaned surface. It is not difficult to understand that, a depth of the through groove 504 satisfies that the first guide wheel 801 at least partially protrudes from a top of the through groove 504 or an end of the extension portion 503.

[0051] Further, the size of the extension portion 503 satisfies that: when the first cleaning element 302 or the second cleaning element 402 is in a natural state, a height of the first guide wheel 801 is smaller than a height of the first cleaning element 302 along a direction in which the first cleaning element 302 protrudes from the first action arm 30, or, a height of the second guide wheel 802 is lower than a height of the second cleaning element 402 along a direction in which the second cleaning element 402 protrudes from the second action arm 40. In this way, the friction between the cleaning assembly and the to-be-cleaned surface can be reduced on the premise of ensuring that the cleaning element is in contact with the to-be-cleaned surface, thereby improving the smoothness of the cleaning assembly during operation.

[0052] In some other optional embodiments, at least one limiting plate 505 is provided at a position of the opening of the sliding portion 501. The at least one limiting plate 505 is configured to prevent the first cleaning element 302 or the second cleaning element 402 from rotating around a central axis of the first action arm 30 or a central axis of the second action arm 40 when the cleaning assembly works. For example, as shown in FIG. 12 and FIG. 13, the limiting plate 505 and the extension portion 503 form a limiting slot.

[0053] In another aspect, a shower device is further provided according to an embodiment of the present application. As shown in FIG. 1, the shower device includes a frame, a screen, and the cleaning assembly described above. A periphery of the screen is at least partially surrounded by the frame. The base 10 of the cleaning assembly is arranged on a surface of the frame parallel to the screen. The frame supports the screen.

[0054] When the cleaning assembly is in a non-working state, the first action arm 30 and the second action arm 40 are located within a projection range of the frame. When the cleaning assembly is in a working state, the first action arm 30 and the second action arm 40 rotate around the second end of the connecting arm 20.

[0055] FIG. 15(a), FIG. 15(c), FIG. 15(d), and FIG. 15(e) sequentially show postures of the cleaning assembly according to the present application from the non-working state to a first extreme position.

[0056] In summary, the cleaning assembly improves the area covered by a single cleaning, and the single cleaning can cover all of the to-be-cleaned surfaces at most, which significantly improves the cleaning efficiency. When the cleaning assembly works, the operator only needs to hold the first action arm and / or the second action arm to sweep on the screen being cleaned, which is convenient for the operator to exert force, and the operator can finish cleaning in a standing posture. Therefore, when the operator uses the cleaning assembly to perform the cleaning at a low position, the operator does not need to bend down or squat significantly like using a towel or a conventional wiper, which is more ergonomic and is beneficial to improving the cleaning efficiency.

[0057] In the shower device according to the embodiment of the present application, the cleaning assembly described above is mounted on the frame, so that the cleaning assembly is located within the projection range of the frame under the action of gravity when it is in the non-working state, and the cleaning difficulty of the shower device is reduced without affecting the esthetics of the shower device.

[0058] The description of the above embodiments is only used to facilitate understanding the method and core idea of the present application. It should be noted that, several improvements and modifications may be made to the present application by those skilled in the art without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
