Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning brush and cleaning equipment. Background Technology

[0002] A fabric cleaning machine is a specialized device for cleaning various fabric items. It uses high-pressure jet technology to spray a mixture of detergent and water onto the stains to dissolve and remove them. Then, through brushing and suction, the mixture of stains and water is drawn into a wastewater tank, keeping the fabric dry and clean. Fabric cleaning machines are highly effective for cleaning various fabric items such as carpets, upholstered furniture, cushions, pet beds, and window seat cushions. They are simple and convenient to operate, quickly and effectively completing the cleaning process.

[0003] In existing fabric cleaning machines, the brush head and suction port are in the same state. When the brush head needs to clean, it needs to apply suction. This requires a lot of running water for cleaning while washing, which wastes a lot of clean water. Utility Model Content

[0024] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0025] The following is for reference. Figures 1-6 The cleaning brush 100 according to an embodiment of the present invention can separate the brushing work of the brush head 30 and the suction work of the nozzle 20, so as to save water consumption and improve water conservation while ensuring cleaning effect.

[0026] Combination Figures 1-6 As shown, the cleaning brush 100 according to the first aspect of this utility model includes a handle 10, a suction nozzle 20, and a brush head 30. The handle 10 facilitates the user's grip and application of brushing force during the cleaning process, allowing the user to easily control the cleaning angle and intensity, avoiding fatigue from prolonged use. The brush head 30 removes dirt through friction with the surface being cleaned. The suction nozzle 20 utilizes internal negative pressure to quickly absorb the dirt and wastewater removed by the brush head 30, preventing secondary adhesion of dirt and avoiding excessive moisture residue after cleaning, which could lead to mold and odor. In summary, the three components work together to form a cleaning process of brushing dirt and suctioning away wastewater, thereby improving cleaning effectiveness and efficiency.

[0027] Specifically, the suction nozzle 20 is connected to the brush handle 10, and the brush head 30 is connected to the brush handle 10. The brush head 30 is located on one side of the suction nozzle 20. One of the suction nozzle 20 and the brush head 30 is retractable relative to the other to change the relative position between the end face of the brush head 30 and the suction port of the suction nozzle 20. For example, the brush head 30 is fixed to the brush handle 10, and the suction nozzle 20 can retract relative to the brush head 30; or the suction nozzle 20 is fixed to the brush handle 10, and the brush head 30 can retract relative to the suction nozzle 20.

[0028] Specifically, the nozzle and brush head 30 are respectively connected to the brush handle 10. The brush handle 10 can provide a mounting carrier for the nozzle and brush head 30. The brush head 30 is located on one side of the suction nozzle 20. The two are independent of each other and do not interfere with each other.

[0029] Optionally, the nozzle 20 is fixed to the brush handle 10, and the brush head 30 can extend and retract relative to the nozzle 20. That is, the position of the nozzle on the brush handle 10 remains unchanged, and the brush head 30 can extend and retract relative to the nozzle 20 according to cleaning needs. For example, when the cleaning brush 100 performs cleaning work, the brush head 30 extends relative to the nozzle 20. At this time, only the brush head 30 contacts the cleaning surface, which makes it easier for the brush head 30 to perform friction and peeling work on the stains on the cleaning surface independently until the stains are completely removed by the brush head 30 before retracting relative to the nozzle 20. At this time, the distance between the nozzle 20 and the dirt on the cleaning surface can be shortened, and the nozzle 20 then performs the suction work. This allows the brushing work and the suction work of the cleaning brush 100 to be independent of each other.

[0030] Moreover, compared to traditional cleaning brushes (where the nozzle and brush head are in the same state, and the nozzle sucks up dirt while the brush head is brushing), the embodiment in this case can separate the brushing work of the brush head 30 from the suction work of the nozzle 20, thereby avoiding the problem of consuming more water while washing and brushing and the problem of dirt easily remaining on the brush head 30, thus improving cleaning efficiency.

[0031] In addition, when the brush head 30 is extended to its full position, the brush head 30 extends beyond the nozzle 20 in the extension direction away from the brush handle 10; when the brush head 30 is retracted to its full position, the brush head 30 is slightly higher / flush / lower than the nozzle 20.

[0032] Therefore, by setting up the cleaning brush 100, the brushing work of the brush head 30 and the suction work of the nozzle 20 can be separated, which can save water consumption and improve water conservation while ensuring the cleaning effect.

[0033] Optionally, the brush handle 10 is also provided with a water outlet 11 for spraying clean water. The water outlet 11 can pre-spray clean water or a cleaning agent diluted with clean water onto the stains on the cleaning surface. At this time, the brush head 30 can then use the cleaning agent to scrub the stains. Afterwards, the suction nozzle 20 can quickly suck the wastewater after dissolving the stains away from the cleaning surface. This forms a closed-loop cleaning process of water spraying (cleaning agent) assistance - scrubbing dirt - suctioning away wastewater, thereby effectively ensuring the cleaning effect of the cleaning brush 100.

[0034] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cleaning brush 100 also includes a telescopic drive mechanism 40, which is disposed in one of the brush handle 10, the suction nozzle 20, and the brush head 30 and is connected to the telescopic drive mechanism 40 for transmission. The telescopic drive mechanism 40 can be connected to the suction nozzle 20 or the brush head 30.

[0035] For example, when the telescopic drive mechanism 40 is connected to the nozzle 20, the telescopic drive mechanism 40 can provide driving force to the nozzle 20, thereby facilitating the nozzle 20 to achieve the telescopic effect.

[0036] Alternatively, combined Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cleaning brush 100 also includes a rotary drive mechanism 50, and the brush head 30 is connected to the rotary drive mechanism 50 for transmission, so that the brush head 30 rotates relative to the brush handle 10.

[0037] Understandably, the rotary drive mechanism 50 can drive the brush head 30 to rotate, thereby reducing the effort required by the user to scrub stubborn stains and improving the automation effect of the brush head 30.

[0038] Moreover, compared to traditional cleaning brushes (where the brush head is fixed and stubborn stains require manual operation to repeatedly scrub the dirt without electric polishing), the embodiment in this case allows the brush head 30 to automatically scrub dirt. In other words, the user only needs to hold the brush handle 10 firmly and guide the brush head 30 to the dirty area to achieve a cleaning effect, thereby effectively reducing the intensity of operation, eliminating the need for repeated vigorous scrubbing, reducing user hand fatigue, and avoiding the risk of blind spots or excessive friction caused by uneven force applied by the user.

[0039] Alternatively, combine Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cleaning brush 100 also includes a telescopic drive mechanism 40 and a rotary drive mechanism 50. The telescopic drive mechanism 40 is disposed on the brush handle 10, and the brush head 30 is drivenly connected to the telescopic drive mechanism 40 and the rotary drive mechanism 50, so that the brush head 30 can rotate relative to the brush handle 10; wherein, the telescopic drive mechanism 40 is telescopically disposed on the rotary drive mechanism 50.

[0040] In other words, the brush head 30 can not only extend and retract under the driving action of the telescopic drive mechanism 40, but also rotate under the driving action of the rotary drive mechanism 50 because the brush head 30 is also connected to the rotary drive mechanism 50.

[0041] As arranged above, on the one hand, the brush head 30 can automatically brush away dirt under the action of the rotary drive mechanism 50. That is, the user only needs to hold the brush handle 10 firmly and guide the brush head 30 to place on the dirty area to achieve the cleaning effect, thereby effectively reducing the intensity of operation, eliminating the need for repeated vigorous brushing, reducing user hand fatigue, and avoiding the risk of blind spots or excessive friction caused by uneven force applied by the user. On the other hand, it also allows the brush head 30 to flexibly extend and retract according to user needs under the action of the telescopic drive mechanism 40. This makes it easier for the brush head 30 to extend relative to the suction nozzle 20, thus helping to separate the brushing work of the brush head 30 from the dirt suction work of the suction nozzle 20, thereby improving the water-saving effect of the cleaning brush 100.

[0042] Specifically, in combination Figures 1-6 As shown, the telescopic drive mechanism 40 includes a mounting shell 41, a fixing frame 42, and a locking mechanism 43. The mounting shell 41 is telescopically disposed within the rotary drive mechanism 50. The fixing frame 42 is rotatably disposed within the mounting shell 41, and the fixing frame 42 telescopically extends and retracts synchronously with the mounting shell 41. The fixing frame 42 is telescopically disposed at the drive end of the rotary drive mechanism 50, and the fixing frame 42 rotates synchronously with the drive end. The fixing frame 42 is connected to the brush head 30 to drive the brush head 30 to rotate. The locking mechanism 43 is disposed between the mounting shell 41 and the rotary drive mechanism 50 to selectively lock the mounting shell 41.

[0043] The brush head 30 is fixedly connected to the mounting frame 42. The mounting frame 42 and the mounting shell 41 extend and retract synchronously. Since both the mounting frame 42 and the mounting shell 41 are telescopically mounted on the rotary drive mechanism 50, the brush head 30 can extend and retract together with the mounting frame 42 and the mounting shell 41 relative to the rotary drive mechanism 50. Moreover, the mounting frame 42 and the drive end of the rotary drive mechanism 50 rotate synchronously, which also enables the brush head 30 to rotate normally, thus ensuring that the brush head 30 can smoothly achieve the extension and rotation effects.

[0044] In addition, the locking mechanism 43 is disposed between the mounting shell 41 and the rotary drive mechanism 50. Since the position of the rotary drive mechanism 50 relative to the brush handle 10 is fixed, the locking mechanism 43 can selectively establish a locking relationship between the mounting shell 41 and the rotary drive mechanism 50 as needed. At this time, the position of the mounting shell 41 is locked, and the position of the fixing bracket 42 connected to the mounting shell 41 is also fixed. At this time, the displacement of the brush head 30 in the extension direction is restricted, which makes it easier for the brush head 30 to maintain a stable position in the extension direction.

[0045] Furthermore, combined Figure 1 , Figure 2 , Figures 4-6As shown, the rotary drive mechanism 50 is provided with at least one locking position 55. The locking mechanism 43 includes an operating member 431 and a locking member 432. The operating member 431 is disposed in the mounting housing 41, and the locking member 432 is disposed in the mounting housing 41. The locking member 432 is in a transmission engagement with the operating member 431, and the locking member 432 selectively engages with at least one locking position 55.

[0046] Alternatively, combined Figures 4-6 As shown, when the operating member 431 moves under the action of the user's external force, the operating member 431 can transmit the force to the mounting shell 41. The mounting shell 41 moves under the action of the operating member 431, and the locking member 432 can move with the mounting shell 41 to one of the multiple locking positions 55 that engage with it. At this time, the locking member 432 engages with one of the locking positions 55 on the rotary drive mechanism 50. At this time, the telescopic drive mechanism 40 and the rotary drive mechanism 50 are in a stable locked state. This makes it convenient for the user to perform stable and continuous cleaning work (such as in the extended state) and also makes it convenient for the user to store the brush head 30 (such as in the retracted state), reducing the risk of interference and collision with the outside world and improving protection. The locking member 432 can also move from the position where it engages with the locking position 55 to the position where it disengages from the locking position 55. At this time, the telescopic drive mechanism 40 and the rotary drive mechanism 50 are in a relatively telescopic and movable state, which makes it convenient for the brush head 30 to flexibly adjust the extended or retracted state according to the needs.

[0047] Alternatively, when the operating member 431 moves under the action of the user's external force, the operating member 431 can transmit the force to the locking member 432. The locking member 432 moves under the action of the operating member and can move with the mounting housing 41 to one of the multiple locking positions 55 that engage with it. At this time, the locking member 432 engages with one of the locking positions on the rotary drive mechanism 50. At this time, the telescopic drive mechanism 40 and the rotary drive mechanism 50 are in a stable locked state.

[0048] Specifically, in combination Figures 4-6 As shown, the operating member 431 is movably disposed on the mounting housing 41, and the operating member 431 forms a mating groove 4311 that opens toward the mounting housing 41. A protrusion 4312 is provided at the bottom of the mating groove 4311. The mounting housing 41 forms a guide hole 411. The locking member 432 is movably disposed in the guide hole 411. When the protrusion 4312 abuts against the locking member 432, the locking member 432 remains locked and engaged with at least one locking position 55.

[0049] In other words, along the extension and retraction direction of the brush head 30, the operating member 431 is movable relative to the mounting shell 41. The operating member 431 is open on the side facing the mounting shell 41 and forms a mating groove 4311. The mounting shell 41 is provided with a guide hole 411. The locking member 432 is movably inserted into the guide hole 411. When the protrusion 4312 on the bottom of the mating groove 4311 abuts against the locking member 432, the locking member 432 is pushed by the protrusion 4312 and moves towards the locking position 55. At this time, the two ends of the locking member 432 abut against the protrusion 4312 and the locking position 55 respectively. At this time, the locking member 432 locks and fixes the mounting shell 41 and the rotary drive mechanism 50 into a whole, which helps to ensure the positional stability of the brush head 30 in the extension and retraction direction.

[0050] Furthermore, combined Figure 2 and Figure 5 As shown, the locking mechanism 43 also includes an elastic element 433, which abuts between the mounting housing 41 and the operating element 431 to provide the operating element 431 with an elastic force to return to its initial position.

[0051] It is understood that the operating member 431 is movable relative to the mounting shell 41 along the telescopic direction, and the elastic member 433 can undergo elastic deformation to generate an elastic restoring force. The elastic member 433 abuts against the mounting shell 41 and the operating member 431. When the operating member 431 moves along the telescopic direction under the force of the user, overcoming the elastic force of the elastic member 433, the operating member 431 shifts relative to the guide hole 411 on the mounting shell 41. The relative position between the protrusion 4312 at the bottom of the mating groove 4311 and the locking member 432 changes. At this time, because the support surface on the protrusion 4312 that is connected to the locking member 432 changes, the locking member 432 returns to its active state within the guide hole 411, thereby locking the member 432 and rotating... When the locking position 55 on the drive mechanism 50 engages in a locking relationship, the telescopic drive mechanism 40 and the rotary drive mechanism 50 are released from their locking relationship, which facilitates the brush head 30 in adjusting its extension and retraction states. When the user releases the force applied to the operating member 431, the operating member 431 returns to its initial position under the elastic restoring force of the elastic member 433. At this time, the protrusion 4312 on the operating member 431 faces the locking member 432 and simultaneously presses the locking member 432 back to the locking position 55. The locking member 432 re-engages with the locking position 55, thereby enabling the rotary drive mechanism 50 and the telescopic drive mechanism 50 to achieve a position locking effect after the user's hand force is removed, thus ensuring the working stability of the brush head 30.

[0052] Specifically, in combination Figure 2 , Figure 5 and Figure 6As shown, the rotary drive mechanism 50 has a stop 51 on the outside of the outermost locking position 55 to cooperate with the locking member 432.

[0053] Along the extension and retraction direction of the brush head 30, the rotary drive mechanism 50 has a stop 51 located outside the outermost locking position 55. The stop 51 can restrict the locking member 432 from continuing to move in the extension direction, that is, restrict the extreme extension position of the brush head 30, thereby avoiding the risk of the extension and retraction drive mechanism 40 disengaging from the rotary drive mechanism 50. Moreover, when the locking member 432 is engaged with the stop 51, the locking member 432 is stably stopped in the position engaged with the outermost locking position 55, thus avoiding the risk of mis-locking of the locking mechanism 43, thereby ensuring the relative positional stability between the extension and retraction drive mechanism 40 and the rotary drive mechanism 50.

[0054] Furthermore, combined Figure 6 As shown, the mounting shell 41 is provided with one of a circumferential limiting groove 52 and a circumferential limiting protrusion 412, and the rotary drive mechanism 50 is provided with the other of a circumferential limiting groove 52 and a circumferential limiting protrusion 412. The circumferential limiting groove 52 and the circumferential limiting protrusion 412 are in circumferential upper limit engagement with the mounting shell 41 so that the mounting shell 41 can extend and retract relative to the rotary drive mechanism 50.

[0055] When the mounting shell 41 is provided with a circumferential limiting groove 52, the rotary drive mechanism 50 is provided with a circumferential limiting protrusion 412; when the mounting shell 41 is provided with a circumferential limiting protrusion 412, the rotary drive mechanism 50 is provided with a circumferential limiting groove 52.

[0056] Optionally, the inner wall of the mounting shell 41 is provided with a circumferential limiting protrusion 412, and the rotary drive mechanism 50 is provided with a circumferential limiting groove 52. The circumferential limiting groove 52 and the circumferential limiting protrusion 412 are engaged in a circumferential upper limit cooperation on the mounting shell 41, which can limit the relative rotation between the mounting shell 41 and the rotary drive mechanism 50 in the circumferential direction of the mounting shell 41, thereby ensuring the relative positional stability of the two in the circumferential direction.

[0057] Specifically, in combination Figure 2 , Figures 4-6 As shown, the rotary drive mechanism 50 includes a housing 53 and a drive member 54. The housing 53 is disposed on the brush handle 10 and is located on one side of the suction nozzle 20. A mounting shell 41 is retractably disposed within the housing 53. The drive member 54 is disposed inside the housing 53 and is provided with a drive shaft 541. A fixing bracket 42 is retractably disposed on the drive shaft 541, and the fixing bracket 42 rotates synchronously with the drive shaft 541. For example, the drive member 54 can be a motor, but is not limited thereto.

[0058] In other words, the outer casing 53 provides installation space for the drive component 54. The drive component 54 can rotate to generate driving force. The output shaft on the drive component 54 transmits the driving force to the mounting bracket 42, which then transmits the driving force to the brush head 30, thus smoothly realizing the rotation of the brush head 30 and achieving the automatic polishing effect of the brush head 30 on stains. The mounting bracket 42 is telescopically mounted on the drive shaft 541. This means that the mounting bracket 42 can extend and retract axially relative to the drive shaft 541, and it can also rotate with the drive shaft 541, thus facilitating the simultaneous extension, retraction, and rotation of the brush head 30.

[0059] Furthermore, combined Figure 2 and Figure 5 As shown, the telescopic drive mechanism 40 also includes a bearing 44, which is disposed between the mounting housing 41 and the fixing frame 42.

[0060] The bearing 44 not only supports the fixed frame 42 but also allows the fixed frame 42 to rotate smoothly, ensuring its relative position and rotational accuracy. This guarantees the operational stability and precision of the fixed frame 42, thereby improving the rotational stability of the brush head 30. Furthermore, the limiting step on the fixed frame 42 provides axial limiting for the bearing 44, ensuring its relative positional stability.

[0061] Specifically, in combination Figure 2 and Figure 3 As shown, the brush head 30 is provided with a first snap-fit ​​part 31, and the fixing frame 42 is provided with a second snap-fit ​​part 421. The first snap-fit ​​part 31 and the second snap-fit ​​part 421 are snap-fitted together.

[0062] The first snap-fit ​​portion 31 on the brush head 30 and the second snap-fit ​​portion 421 on the fixing frame 42 engage with each other, thus connecting the brush head 30 and the fixing frame 42 into a whole. Compared with other connection methods (such as screw connection, adhesive connection, etc.), the snap-fit ​​connection does not require additional parts to connect the brush head 30 and the fixing frame 42 into a whole, avoiding unnecessary material consumption. It can also provide sufficient connection and holding force for the brush head 30 and the fixing frame 42, ensuring that the brush head 30 will not fall off the fixing frame 42.

[0063] Moreover, the snap-fit ​​connection structure is simple and reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick combination and separation of the brush head 30 and the fixing frame 42), which can effectively reduce the time and cost required for maintenance and replacement.

[0064] Alternatively, combined Figure 1As shown, the brush head 30 is constructed in a Reuleaux triangle. This arrangement, compared to a circular brush head, can reduce material consumption without reducing the cleaning area, thereby improving economy.

[0065] The cleaning device according to a second aspect embodiment of the present invention includes the cleaning brush 100 of the above embodiment. Thus, the cleaning device having the cleaning brush 100 can effectively save water while ensuring cleaning effect, thereby improving the market competitiveness of the cleaning device. For example, the cleaning device can be a fabric cleaning machine, but is not limited thereto.
