[0041] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0042] Reference is made below to Figures 1 - 10 describe a cleaning head assembly 1 according to an embodiment of the present utility model. The cleaning head assembly 1 can flexibly adjust the height of the first cleaning head 3, so as to flexibly switch between the first cleaning head 3 and the second cleaning head 4 for the user to use, realize different cleaning functions, improve the versatility and flexibility of the cleaning head assembly 1, greatly improve the cleaning efficiency and cleaning effect, and enhance the user experience.

[0043] As Figures 1 - 10 shown, a cleaning head assembly 1 according to an embodiment of the present utility model includes: a housing 2, a first cleaning head 3, a second cleaning head 4, and a swinging structure 5.

[0044] Both the first cleaning head 3 and the second cleaning head 4 are installed on the housing 2, and the first cleaning head 3 is movably connected to the housing 2. That is to say, the inside of the housing 2 is hollow to form an installation cavity for installing the first cleaning head 3 and the second cleaning head 4. The first cleaning head 3 can move relative to the housing 2. The first cleaning head 3 and the second cleaning head 4 are used for cleaning and each has different cleaning functions to adapt to different cleaning needs. For example, when the cleaning head assembly 1 is used to clean glass, the first cleaning head 3 can be set as a squeegee, and the second cleaning head 4 can be set as a cleaning cloth to achieve the functions of wiping stains on the glass surface and scraping water, making the glass brighter and clearer. Or, the cleaning head assembly 1 can also be used for other combined functions. For example, the first cleaning head 3 can be set as a brush head to remove stubborn stains, and the second cleaning head 4 can be set as a cleaning cloth or a soft head, etc., for wiping, so as to achieve the cleaning function and can be applied to more cleaning scenarios. Among them, the first cleaning head 3 or the second cleaning head 4 can also be set as a small soft brush head to facilitate effective cleaning of places such as corners and gaps that are not easy to clean, and improve the cleaning effect.

[0045] Thus, through the combined design of the first cleaning head 3 and the second cleaning head 4, the cleaning head assembly 1 has diversified cleaning functions, is suitable for complex and changeable cleaning scenarios, can meet different needs of users, improves the cleaning efficiency, and enhances the cleaning effect.

[0046] Furthermore, the swing structure 5 is swingably mounted on the housing 2, and the swing structure 5 is used to drive the first cleaning head 3 to move up and down relative to the housing 2.

[0047] Specifically, the swing structure 5 is mounted inside the housing 2 to provide mounting support and protection for the swing structure 5. The swing structure 5 is connected to the first cleaning head 3. In practice, when the swing structure 5 swings relative to the housing 2, the swing structure 5 can drive the first cleaning head 3 to rise or fall relative to the housing 2. At the same time, the second cleaning head 4 remains fixed relative to the housing 2. In this way, when the swing structure 5 swings to drive the first cleaning head 3 to rise, the height of the first cleaning head 3 is higher than that of the second cleaning head 4. At this time, the user can use the first cleaning head 3 for cleaning. When the swing structure 5 swings to drive the first cleaning head 3 to fall, the height of the first cleaning head 3 is lower than that of the second cleaning head 4. At this time, the user can use the second cleaning head 4 for cleaning.

[0048] Of course, it is also possible to make the height of the first cleaning head 3 the same as the height of the second cleaning head 4 relative to the housing 2 by swinging the swing structure 5. In this way, during actual use, the first cleaning head 3 and the second cleaning head 4 can be used for cleaning at the same time. Exemplarily, when the first cleaning head 3 is a squeegee and the second cleaning head 4 is a cleaning cloth, moisture can be scraped while removing stains, enhancing the cleaning efficiency. And when the cleaning work is completed, the swing structure 5 can be further operated to swing so that the height of the first cleaning head 3 is the same as the height of the second cleaning head 4 relative to the housing 2, which is beneficial for storage and facilitates cleaning of the two cleaning heads.

[0049] Thus, through the reciprocating swing of the swing structure 5, the first cleaning head 3 is driven to move up and down to flexibly adjust the height of the first cleaning head 3 relative to the second cleaning head 4, so that the first cleaning head 3 and the second cleaning head 4 can be flexibly switched for the user to use, thereby realizing different cleaning functions, improving the versatility and flexibility of the cleaning head assembly 1, greatly enhancing the cleaning efficiency and cleaning effect, and improving the user experience.

[0050] It should be noted that the swing structure 5 can also be connected to the second cleaning head 4, that is, the first cleaning head 3 and the second cleaning head 4 are both connected to the swing structure 5. Thus, when the swing structure 5 swings, it drives the first cleaning head 3 to rise and the second cleaning head 4 to fall, or drives the first cleaning head 3 to fall and the second cleaning head 4 to rise, realizing the flexible switching between the first cleaning head 3 and the second cleaning head 4.

[0051] According to the cleaning head assembly 1 of the embodiment of the present utility model, by simultaneously providing the first cleaning head 3 and the second cleaning head 4, the cleaning head assembly 1 has diversified cleaning functions and is suitable for complex and changeable cleaning scenarios. By providing the swinging structure 5, when the swinging structure 5 swings, it drives the first cleaning head 3 to flexibly lift relative to the housing 2, so as to flexibly adjust the height of the first cleaning head 3, thereby flexibly switching between the first cleaning head 3 and the second cleaning head 4 for the user to use, realizing different cleaning functions, improving the versatility and flexibility of the cleaning head assembly 1, greatly improving the cleaning efficiency and cleaning effect, and enhancing the user experience.

[0052] In some embodiments, the swinging structure 5 includes a swinging shaft 51 and a connecting plate 52. The swinging shaft 51 is rotatably installed in the housing 2. The connecting plate 52 is connected to the outer peripheral wall of the swinging shaft 51. The connecting plate 52 is connected to at least one of the first cleaning head 3 and the second cleaning head 4, that is, the connecting plate 52 can be connected to the first cleaning head 3, or connected to the second cleaning head 4, or simultaneously connected to the first cleaning head 3 or the second cleaning head 4. Thus, when an external force drives the swinging shaft 51 to swing in the housing 2, the swinging shaft 51 can drive the connecting plate 52 to swing together. When the connecting plate 52 swings, it further drives the first cleaning head 3 or the second cleaning head 4 connected to the connecting plate 52 to rise or fall, thereby converting the rotational motion of the swinging shaft 51 into a linear motion of the cleaning head, realizing the adjustment of the height of the first cleaning head 3 or the second cleaning head 4, and further realizing the flexible switching between the first cleaning head 3 and the second cleaning head 4.

[0053] Specifically, in this embodiment, the example where the connecting plate 52 in the drawings is simultaneously connected to the first cleaning head 3 and the second cleaning head 4 is used for illustration. As Figure 4 and Figure 5 shown, the swinging structure 5 includes a swinging shaft 51 and a connecting plate 52. The housing 2 is open upward. The first cleaning head 3 and the second cleaning head 4 are installed above the housing 2. The swinging shaft 51 is installed in the housing 2 along the length direction of the housing 2, and the swinging shaft 51 can rotate around its own axis in the housing 2. Among them, the connecting plate 52 is fixedly connected to the outer peripheral wall of the swinging shaft 51. In practice, the connecting plate 52 can be connected to the outer peripheral wall of the swinging shaft 51 by connection methods such as welding and bolt connection to improve its connection reliability, so that the connecting plate 52 can keep synchronous movement with the swinging shaft 51 and can bear the load transmitted by the cleaning head, preventing the connecting plate 52 from breaking and affecting the switching between the first cleaning head 3 and the second cleaning head 4.

[0054] As Figure 7As shown, both ends of the connecting plate 52 are simultaneously connected to the first cleaning head 3 and the second cleaning head 4. With this arrangement, when the actual swing axis 51 swings in one direction, it can rotate a certain angle clockwise or counterclockwise, driving the connecting plate 52 to swing back and forth in the front-back direction as shown in the figure. As Figure 8 shown, when the connecting plate 52 swings backward, it drives the first cleaning head 3 in the front to descend and the second cleaning head 4 in the back to ascend. At this time, the connecting plate 52 is higher at the back and lower at the front, that is, the height of the second cleaning head 4 is greater than the height of the first cleaning head 3, and the user can use the second cleaning head 4 for cleaning. Similarly, as Figure 9 shown, when the connecting plate 52 swings forward, it drives the first cleaning head 3 in the front to ascend and the second cleaning head 4 in the back to descend. At this time, the connecting plate 52 is higher at the front and lower at the back, that is, the height of the first cleaning head 3 is greater than the height of the second cleaning head 4, and the user can use the first cleaning head 3 for cleaning. Thus, by the swing of the swing axis 51 driving the connecting plate 52 to swing back and forth, the switching between the first cleaning head 3 and the second cleaning head 4 is realized.

[0055] In some embodiments, the connecting plate 52 is provided with a connecting portion, and the connecting portion is distributed at an interval from the axis of the swing axis 51. The connecting portion is used to connect to the first cleaning head 3 or the second cleaning head 4, that is, the connecting portion can be connected to the first cleaning head 3, or can be connected to the second cleaning head 4, or can be simultaneously connected to both the first cleaning head 3 and the second cleaning head 4. By distributing the connecting portion at an interval from the axis of the swing axis 51, it is possible to avoid interference and disturbance between the connecting portion and the swing axis 51 during the movement process, thereby affecting the movement of the first cleaning head 3 and the second cleaning head 4.

[0056] In some embodiments, there are two connecting portions, and the two connecting portions are respectively located at both ends of the connecting plate 52, and the swing axis 51 is located between the two connecting portions. Among them, one of the two connecting portions is used to connect to the first cleaning head 3 and the other is used to connect to the second cleaning head 4.

[0057] Specifically, as Figures 6 - 9As shown, the connecting plate 52 is configured into three parts, a middle plate part and side plate parts on both sides of the middle. The middle plate part is connected to the swing shaft 51. A connecting part is provided on the side plate part at the front end to be connected to the first cleaning head 3, and a connecting part is also provided on the side plate part at the rear end to be connected to the second cleaning head 4. With such a setting, the two connecting parts are both spaced apart from the axis of the swing shaft 51 and are located on the front and rear sides of the swing shaft 51, that is, the swing shaft 51 is located between the two connecting parts, which can enable the first cleaning head 3 and the second cleaning head 4 to rise or fall smoothly during the swinging process of the connecting plate 52, avoiding unnecessary interference or resistance between the two connecting parts and the swing shaft 51 during the movement of the swing shaft 51 and affecting the movement of the first cleaning head 3 and the second cleaning head 4. At the same time, by reasonably spacing the two connecting parts from the axis of the swing shaft 51, the stability and balance of the entire cleaning head assembly 1 can be improved.

[0058] In some embodiments, the connecting part is configured as a first connecting hole 521, and the first cleaning head 3 and / or the second cleaning head 4 is formed with a second connecting hole 41. The first connecting hole 521 and the second connecting hole 41 are used to pass through and connect a connecting rotating shaft 56.

[0059] Specifically, as Figure 6 shown, the connecting part is configured as a first connecting hole 521, that is, first connecting holes 521 penetrating along the thickness direction of the connecting plate 52 are provided at both ends of the connecting plate 52. Second connecting holes 41 are provided on both the first cleaning head 3 and the second cleaning head 4, and the first connecting hole 521 corresponds to the second connecting hole 41, that is, they are opposite in position, and the shapes and sizes of the first connecting hole 521 and the second connecting hole 41 are adapted to the connecting rotating shaft 56. Thus, the connecting rotating shaft 56 can pass through the first connecting hole 521 and the second connecting hole 41. Therefore, the first cleaning head 3, the second cleaning head 4 and the connecting plate 52 are firmly rotationally connected through the connecting rotating shaft 56, which can ensure the connection reliability of the cleaning head, avoid loosening or falling off during its movement, and at the same time, enable the first cleaning head 3 and the second cleaning head 4 to rotate to a certain extent relative to the connecting part, realize the transmission of force, and smoothly convert the swinging movement of the connecting plate 52 into the linear lifting and lowering movement of the first cleaning head 3 and the second cleaning head 4.

[0060] In some embodiments, two spaced-apart and oppositely distributed support plates 42 are provided on the first cleaning head 3 and / or the second cleaning head 4, and the connecting part extends between the two support plates 42 to be movably connected to the two support plates 42.

[0061] Specifically, as Figure 7As shown, two support plates 42 are provided on both the first cleaning head 3 and the second cleaning head 4. The two support plates 42 can provide stable support for the first cleaning head 3 and the second cleaning head 4, ensuring the stability of their movement. Second connection holes 41 penetrating in the thickness direction are provided on both support plates 42. A first connection hole 521 penetrating in the thickness direction is provided on the connecting plate 52. The first connection hole 521 and the second connection hole 41 are in alignment in the front-back direction, and the two support plates 42 are spaced apart and distributed relatively in the front-back direction shown in the figure. The distance between them is the thickness dimension of the connecting plate 52 or slightly larger than the thickness dimension of the connecting plate 52, so that the connecting plate 52 can smoothly extend between the two support plates 42 and be movably connected to the two support plates 42 through a connecting rotating shaft 56. That is, the connecting rotating shaft 56 can sequentially pass through the second connection hole 41 on the first support plate 42, the first connection hole 521 on the connecting plate 52, and the second connection hole 41 on the second support plate 42, so that the support plate 42 can rotate relative to the connecting plate 52, and further the first cleaning head 3 and the second cleaning head 4 can rotate to a certain extent relative to the connecting part, realizing the transmission of force and smoothly converting the swinging motion of the connecting plate 52 into the linear lifting motion of the first cleaning head 3 and the second cleaning head 4.

[0062] In some embodiments, there are multiple connecting plates 52, that is, the connecting plates 52 can be set to two, three or even more. Setting multiple connecting plates can provide multiple connection points and support points for the first cleaning head 3 and the second cleaning head 4, so that the first cleaning head 3 and the second cleaning head 4 can be connected to the connecting plate 52 at multiple positions, thereby improving the reliability and stability of the lifting motion of the first cleaning head 3 and the second cleaning head 4.

[0063] Moreover, the multiple connecting plates 52 are spaced apart and distributed along the length direction of the swinging shaft 51. With this setting, the multiple connecting plates 52 can be evenly distributed on the swinging shaft 51, so that the movement of each position of the first cleaning head 3 and the second cleaning head 4 is ensured, further improving the reliability and stability of the lifting motion of the first cleaning head 3 and the second cleaning head 4.

[0064] Specifically, as Figure 5 and Figure 6 shown, two connecting plates 52 are provided on the swinging shaft 51, and the two connecting plates 52 are spaced apart and distributed along the left-right direction shown in the figure in the length direction of the swinging shaft 51. One connecting plate 52 is located on the left side of the swinging shaft 51, and the other connecting plate 52 is located on the right side of the swinging shaft 51. In this way, the first cleaning head 3 and the second cleaning head 4 are connected to the connecting plate 52 at two positions, ensuring the movement stability of the first cleaning head 3 and the second cleaning head 4 in the left area and the right area.

[0065] In some embodiments, the swinging structure 5 further includes a swinging member 53. The swinging member 53 is connected to the swinging shaft 51, and at least a part of the swinging member 53 extends outside the housing 2. The swinging member 53 is used to drive the swinging shaft 51 to swing.

[0066] Specifically, the swinging structure 5 is provided with a swinging member 53. A part of the swinging member 53 extends outside the housing 2 to facilitate the user to operate the swinging member 53. The swinging member 53 is fixedly connected to the swinging shaft 51. Thus, when the user turns the swinging member 53, the swinging member 53 can drive the swinging shaft 51 to swing synchronously. Further, the swinging of the swinging shaft 51 drives the connecting plate 52 to swing synchronously, and then the connecting plate 52 drives the first cleaning head 3 or the second cleaning head 4 to move up and down.

[0067] In some embodiments, there are multiple swinging members 53, that is, the swinging members 53 can be set to two, three or even more. Setting multiple swinging members 53 enables the swinging shaft 51 to be connected to the swinging members 53 at multiple positions. Thus, the swinging shaft 51 can be driven to swing at multiple positions by the swinging members 53, so as to improve the movement reliability and stability of the swinging shaft 51 and make it rotate stably.

[0068] And the multiple swinging members 53 are spaced apart along the length direction of the swinging shaft 51. With such a setting, the whole of the swinging shaft 51 can be driven to swing by the swinging members 53, further improving the movement reliability and stability of the swinging shaft 51.

[0069] In some other embodiments, there are two swinging members 53, and the connecting plate 52 is located between the two swinging members 53.

[0070] Specifically, as Figure 6 shown, two swinging members 53 are connected to the swinging shaft 51. The two swinging members 53 are connected to the left and right ends of the swinging shaft 51, and the connecting plate 52 is located between the two swinging members 53. Thus, the whole of the swinging shaft 51 can be driven to swing by the swinging members 53 at the left and right ends, making the movement of the swinging members 53 more stable. By arranging the connecting plate 52 between the two swinging members 53, the interference between the movements of the swinging members 53 and the connecting plate 52 can be avoided, so as to ensure that both the swinging members 53 and the connecting plate 52 can work effectively.

[0071] In some embodiments, the swinging member 53 includes a pushing portion 531 and a cooperating portion 532. The pushing portion 531 is connected to the cooperating portion 532. The cooperating portion 532 is connected to the outside of the swinging shaft 51 and is circumferentially limited and cooperated with the swinging shaft 51. The pushing portion 531 extends outside the housing 2.

[0072] Specifically, as Figure 10As shown, the swing member 53 includes a pushing portion 531 and a matching portion 532. The pushing portion 531 is located at the lower portion of the matching portion 532. The pushing portion 531 is configured to push the plate to be fixedly connected to the lower portion of the matching portion 532. Figure 3 As shown, a corresponding swing hole is provided on the shell 2, so that the pushing portion 531 can pass through the swing hole and extend to the outside of the shell 2, so as to facilitate the user's hand operation to push the pushing portion 531 to swing, and the shape and size of the matching portion 532 are adapted to the shape and size of the swing shaft 51, so that the matching portion 532 can be connected to the outside of the swing shaft 51 and cooperate with the circumferential limit of the swing shaft 51, that is, to limit the relative rotation between the matching portion 532 and the swing shaft 51, so as to ensure that the swing member 53 can drive the swing shaft 51 to swing synchronously during the swinging process, thereby ensuring the stability and accuracy of the swing member 53 and the swing shaft 51 during the swinging process.

[0073] In some embodiments, the mating portion 532 is formed with a mating groove 5321, and at least a portion of the swing shaft 51 is located in the mating groove 5321, wherein one of the inner wall of the mating groove 5321 and the outer wall of the swing shaft 51 is provided with a limiting protrusion 54 and the other limiting recess 55, and the limiting protrusion 54 and the limiting recess 55 are inserted in the radial direction of the swing shaft 51 and are limitedly mated along the circumferential direction.

[0074] That is to say, a matching groove 5321 can be provided on the matching portion 532, and a limiting protrusion 54 can be provided on the inner wall of the matching groove 5321, and a limiting recess 55 can be provided on the outer wall of the swing shaft 51. Alternatively, a limiting recess 55 can be provided on the inner wall of the matching groove 5321, and a limiting protrusion 54 can be provided on the outer wall of the swing shaft 51, and the limiting protrusion 54 is adapted to the limiting recess 55, and the limiting protrusion 54 extends along the radial direction of the swing shaft 51 so that the limiting protrusion 54 can be tightly inserted into the limiting recess 55 along the radial direction of the swing shaft 51. The movable shaft 51 is axially supported, and the circumferential limitation of the swing shaft 51 is achieved by the plug-in fit of the limiting recess 55 and the limiting protrusion 54, that is, the relative rotation between the swing shaft 51 and the swing member 53 is limited, avoiding shaking or deviation when the swing member 53 drives the swing shaft 51 to rotate, thereby improving the connection stability and reliability between the swing member 53 and the swing shaft 51, improving the swinging accuracy, improving the user experience, and the plug-in fit of the limiting recess 55 and the limiting protrusion 54, the assembly process is simple and fast, and the assembly efficiency of the cleaning head assembly 1 is improved.

[0075] Specifically, if Figure 6 and Figure 10As shown, the mating portion 532 is configured as a hollow semi-cylindrical structure to match the shape of the swing shaft 51. Limiting protrusions 54 extend downward radially for a certain distance on the outer walls at both ends of the swing shaft 51. Corresponding limiting notches 55 are provided on the inner wall of the mating portion 532. It can be understood that the depth of the limiting notch 55 is the same as the length of the downward extension of the limiting protrusion 54, and the shapes of the limiting notch 55 and the limiting protrusion 54 are the same. In this way, the limiting notch 55 and the limiting protrusion 54 can be tightly inserted along the radial direction of the swing shaft 51, improving the connection stability and reliability between the swing member 53 and the swing shaft 51.

[0076] In some embodiments, the first cleaning head 3 is connected to a first mounting base 61, the second cleaning head 4 is connected to a second mounting base 62, and the swing structure 5 is rotatably connected to the first mounting base 61 and the second mounting base 62 respectively. That is, the swing of the swing structure 5 drives the first mounting base 61 and the second mounting base 62 to move up and down, so as to push the first cleaning head 3 and the second cleaning head 4 to move up and down.

[0077] Specifically, the first mounting base 61 is used to fixedly support the first cleaning head 3, and the second mounting base 62 is used to fixedly support the second cleaning head 4. As Figure 7 shown, the first cleaning head 3 is mounted above the first mounting base 61, the second cleaning head 4 is mounted above the second mounting base 62, and two spaced and oppositely distributed support plates 42 are provided on both the first mounting base 61 and the second mounting base 62. Second connection holes 41 are provided on both support plates 42, and corresponding first connection holes 521 are provided on the connecting plate 52. The connecting rotating shaft 56 sequentially passes through the second connection hole 41 on the first support plate 42, the first connection hole 521 on the connecting plate 52, and the second connection hole 41 on the second support plate 42, thereby realizing the rotatable connection between the swing structure 5 and the first mounting base 61 and the second mounting base 62 respectively. With such a setting, when the swing structure 5 swings, the connecting plate 52 swings to drive the first mounting base 61 and the second mounting base 62 to move up and down, and the connecting plate 52 can rotatably support the first mounting base 61 and the second mounting base 62 to realize the transmission of force, thereby converting the swing movement of the connecting plate 52 into the linear up and down movement of the first mounting base 61 and the second mounting base 62.
