[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application No. 202323066447.2, filed on November 13, 2023, entitled “Cleaning Accessories and Vacuum Cleaners,” and priority to Chinese patent application No. 202323068344.X, filed on November 13, 2023, entitled “Cleaning Appliances,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the technical field of cleaning equipment, and in particular to a cleaning accessory and a vacuum cleaner including the cleaning accessory. Background Art

[0004] Pet hair is finer than human hair and contains natural oils, making it easily absorbed by clothing, carpets, and other surfaces. Related art provides a cleaning brush whose teeth can penetrate the fur layer to capture shed pet hair and dander. After combing, the teeth rebound, and the hair adsorbed on the comb is directly sucked into the dust bin of the vacuum cleaner, reducing pet pollution to the indoor environment. However, when combing a pet's hair, the user needs to constantly press the operating element with their fingers, which is quite laborious. Pressing the operating element while combing the pet's hair makes it difficult to control the force applied by the brush to the pet, which can cause discomfort to the pet and lead to overreaction.

[0011] Optionally, the actuator is a pressing member connected to the outer shell of the brush head and movable relative to the outer shell. The pressing member can be directly connected to the pushing plate, or the pressing member can be connected to the pushing plate via a transmission assembly. By applying force to the pressing member, the pushing plate is moved to block the outer ends of the combing needles. The direction of applying force to the pressing member is substantially parallel to the longitudinal extension direction of the combing needles, or is angled with the longitudinal extension direction of the combing needles. A first elastic member is provided between the pressing member and the outer shell. When the first elastic member releases the pressure on the pressing member, the pressing member returns to its initial position.

[0012] Optionally, the actuator includes an operating member that can move along the axial direction of the brush handle. The operating member can be a pull ring or a push button, and the specific details are not limited. The user operates the operating member to control the movement of the pushing plate. Specifically, a transmission assembly is provided in the housing cavity of the brush head. The operating member is connected to the pushing plate through the transmission assembly. By applying a thrust or pull force to the operating member, the transmission assembly drives the pushing plate to move to the outer end that is blocked by the combing needles. A second elastic member is further provided between the pushing plate and the brush head so that after the force on the operating member is released, the pushing plate rebounds to its initial position. The pushing plate is adjacent to the combing needle plate in the initial position, and the combing needles on the combing needle plate are exposed from the through holes of the pushing plate.

[0013] Preferably, the push knob or the pull ring is arranged on the brush head at one end close to the brush handle, which is convenient for the user to operate with the thumb; during normal combing, the push knob or the pull ring is not operated, and the combing needles extend out of the hair-pushing plate. The user holds the brush handle to comb the pet's hair. After combing, the push knob is pushed forward or the pull ring is pulled backward, and the hair-pushing plate moves to self-clean the combing needles. The hair and dirt peeled off from the combing needles are sucked into the dust cylinder of the vacuum cleaner through the suction port on the surface of the hair-pushing plate, and the transmission component converts the operating force along the axis of the brush handle into a force that pushes the hair-pushing plate to move up and down relative to the brush head.

[0014] Furthermore, the hair pushing plate includes a first guide portion, the first guide portion passes through the pin plate, the pin plate is provided with a slide groove that cooperates with the first guide portion, and the first guide portion includes a limiting structure to limit the movement of the hair pushing plate. Optionally, a second elastic member is located between the first guide portion and the pin plate, and is used to floatingly support the hair pushing plate so that the hair pushing plate is close to the pin plate.

[0015] Furthermore, the needle plate includes a needle felt seat, a needle felt pad, and a needle felt cover. The needle felt pad is located between the needle felt seat and the needle felt cover.

The pushing plate 212 is provided with a first guide portion 2122. The first guide portion 2122 passes through the slide groove 2110. A second elastic member 41 is also provided at the first guide portion 2122 for floating support of the pushing plate 212 and making the pushing plate 212 close to the combing plate 211 after the operating force on the actuator 30 is released.

[0063] As shown in FIG6 , the needle plate 211 includes a needle felt seat 2111 , a needle felt pad 2112 , needles 21121 fixed to the needle felt pad 2112 , and a needle felt cover 2113 . The needle felt pad 2112 is disposed between the needle felt seat 2111 and the needle felt cover 2113 .

[0064] As shown in Figures 3-6, the cleaning accessory 1 includes a housing 2 and a conduit 20. The conduit 20 is located within the housing 2 and is used to connect to a negative pressure source. The hair-pushing plate 212 is provided with a through-hole 2121 and a suction port 2123. The combing needles 21121 pass through the through-hole 2121, and the hair-pushing plate 212 is movable relative to the combing needles 21121. The housing 2 includes a brush head 21 and a brush handle 22. The conduit 20 is located within the brush handle 22. The actuator 30 is located in the brush head 21 and acts on the hair-pushing plate 212 via a transmission assembly 4. The actuator 30 and the housing 2 are connected by a first elastic member 31. When the actuator 30 is deactivated, the actuator 30 returns to its initial position.

[0065] A connecting tube 21110 is provided on the needle felt seat 2111, and the suction port 2123 of the hair pushing plate 212 can be movably inserted into the connecting tube 21110. The first guide portion 2122 of the hair pushing plate 212 slides in the slide groove 2110 of the combing needle plate 211. The brush handle 22 includes a gripping portion 220 and a coupling portion 221, and the coupling portion 221 is used to connect to a vacuum cleaner.

[0066] Example 2:

[0067] In conjunction with Figures 1 to 10, the cleaning accessory 1 according to the embodiment of the present disclosure includes a shell 2, a combing plate 211, a hair pushing plate 212 and a drive assembly; the shell 2 includes a brush head 21 and a brush handle 22, the brush head 21 has a accommodating cavity with an open bottom, the combing plate 211 is fixedly arranged at the open position of the accommodating cavity, the hair pushing plate 212 is located on the outside of the combing plate 211 and can be moved relative to the combing plate 211, the drive assembly includes an actuator 30 and a transmission assembly 4, the actuator 30 is located on the surface of the brush head 21, and the transmission assembly 4 is located in the accommodating cavity of the brush head 21, and the movement of the hair pushing plate 212 is controlled by triggering the actuator 30.

[0068] Specifically, the brush head 21 has a suction port 2123, the air inlet of the suction port 2123 extends to the surface of the hair pushing plate 212, and the combing needle plate 211 is provided with combing needles 21121. After combing the pet's hair, the hair pushing plate 212 is moved to the outer end covered by the combing needles 21121. The hair and dirt on the combing needles 21121 are guided to the surface of the hair pushing plate 212, and then the hair and dirt are sucked away by the negative pressure generated at the suction port 2123. During the combing process of the cleaning accessory 1, the combing needle 21121 has the function of a comb or a brush to peel off the hair and dander fallen off the pet's skin. At the same time, some hair, dander and allergens will be sucked into the dust cylinder of the vacuum cleaner through the suction port 2123 of the brush head 21. At the same time, some hair may be adsorbed on the combing needle 21121. When the hair on the combing needle 21121 accumulates to a certain extent, the hair on the combing needle 21121 is cleaned by pushing the hair plate 212, which solves the problem of hair flying that traditional combing tools cannot cope with, and realizes combing, hair removal and self-cleaning in one step.

[0069] The brush plate 212 is connected to the transmission assembly 4 in the housing of the brush head 21, and the combing needles 21121 can pass through the through holes 2121 of the brush plate 212. The transmission assembly 4 drives the brush plate 212 to move between an extended state and a retracted state. When the brush plate 212 is in the retracted state, the combing needles 21121 pass through the brush plate 212; when the brush plate 212 is in the extended state, the combing needles 21121 retract relative to the brush plate 212. Specifically, as shown in Figure 8, when the hair pushing plate 212 is in the retracted state, the combing needle 21121 can pass through the hair pushing plate 212, thereby facilitating the combing needle 21121 to extend into the pet's hair. As shown in Figure 9, when the hair pushing plate 212 is in the pushed-out state, the combing needle 21121 retracts relative to the hair pushing plate 212. At this time, the hair and dirt on the combing needle 21121 can be pushed down by the hair pushing plate 212 and sucked away under the negative pressure of the suction port 2123, which facilitates the self-cleaning of the cleaning accessory 1.

[0070] The cleaning attachment 1 is connected to the vacuum cleaner via the brush handle 22. During operation, the brush handle 22 can be held by hand to comb pet hair. Fallen pet hair is entangled with the combing pins 21121. When the hair on the combing pins 21121 needs to be cleaned, the hair-pushing plate 212 is driven outward and moves along the combing pins 21121. That is, the hair-pushing plate 212 moves outward and the combing pins 21121 are relatively retracted. The hair and dirt on the combing pins 21121 are guided to the surface of the hair-pushing plate 212. The pet hair is then sucked into the dust cylinder of the vacuum cleaner through the suction port on the surface of the hair-pushing plate 212. The hair-pushing plate 212 is provided with a through hole 2121. When the hair-pushing plate 212 is in the retracted state, the combing pins 21121 can pass through the through hole 2121.

[0071] As shown in Figures 8 to 11, the actuator 30 can move in a predetermined direction to drive the hair-pushing plate 212 to be pushed out. The predetermined direction is a direction along the axis of the grip portion 220 of the cleaning attachment 1, or a predetermined direction away from the grip portion 220 of the cleaning attachment 1. Therefore, the user can hold the grip portion 220 with their hand and use their thumb to drive the actuator 30 to drive the hair-pushing plate 212, which can facilitate the application of force to the actuator 30, making the use of the cleaning attachment 1 more labor-saving. The grip portion 220 refers to a part of the brush handle 22.

[0072] Transmission assembly 4 is driven by actuator 30, to press hair-pushing plate 212 and drive hair-pushing plate 212 to unfold. That is to say, transmission assembly 4 can convert the operating force along predetermined direction into the axial movement along the combing needle 21121 of hair-pushing plate 212.

[0073] One end of the transmission component 4 is rotatably connected to the brush head 21, and the actuator 30 abuts against the transmission component 4 and can control the transmission component 4 to rotate and press toward the pushing plate 212. Through the rotation of the transmission component 4, the force of the actuator 30 can be stably transmitted to the pushing plate 212, thereby improving the stability of the movement of the pushing plate 212.

[0074] A pipe 20 with an air duct is provided within the brush handle 22, and the suction port 2123 of the hair-pushing plate 212 is connected to the inlet of the pipe 20 via a connecting pipe 21110. The accommodating chamber and the connecting pipe 21110 are separated, and the transmission assembly 4 is disposed within the accommodating chamber. The operating portion of the actuator 30 protrudes from the outer surface of the brush head 21. As the hair-pushing plate 212 moves relative to the pin plate 211, the suction port 2123 of the hair-pushing plate 212 moves within the connecting pipe 21110.

[0075] The hair pushing plate 212 includes a plate body and a first guide portion 2122. The plate body is basically parallel to the combing plate 211. The first guide portion 2122 passes through the combing plate 211. The transmission assembly 4 presses the first guide portion 2122 to drive the hair pushing plate 212 to unfold.

[0076] The pin plate 211 is provided with a slide 2110. A first guide portion 2122 extends through the slide 2110 and is movable along the slide 2110. A stop plate is provided at the top of the first guide portion 2122 to limit the movement of the hair-pushing plate 212. A second elastic member 41 is also provided at the first guide portion 2122 to provide an elastic force that forces the hair-pushing plate 212 toward the pin plate 211. The second elastic member 41 maintains the hair-pushing plate 212 in a retracted position. This eliminates the need to operate the actuator 30 when combing hair using the cleaning attachment 1, saving effort during the combing process.

[0077] The actuator 30 is arranged on the surface of the brush head 21, and a transmission assembly 4 is provided inside the brush head 21. A first elastic member 31 is provided between the transmission assembly 4 and / or the actuator 30. After the operating force on the actuator 30 is released, the first elastic member 31 causes the actuator 30 and / or the transmission assembly 4 to return to their initial position.

[0078] As shown in FIG7 , in some embodiments, a flexible connection is provided between the needles 21121 and the needle felt pad 2112. The needles 21121 can be fixed to the needle felt pad 2112, which is made of rubber. The fixed ends of the needles 21121 are provided with first and second positioning portions. These first and second positioning portions are spaced apart along the length of the needles 21121 and located on either side of the needle felt pad 2112, ensuring a stable fit between the needles 21121 and the pad. The ends of the needles 21121 that contact the pet are spherical. Because the connection between the needles 21121 and the pad 2112 is non-rigid, the needles 21121 can tilt at a certain angle when in contact with the pet. Furthermore, the spherical shape of the contact ends prevents excessive force applied to the pet, thus preventing sudden overreactions.

[0079] The brush handle 22 has a joint 221 for connection to a vacuum cleaner. The needle plate 211 includes a needle felt seat 2111, a needle felt pad 2112, and a needle felt cover 2113. A connecting tube 21110 is provided on the needle felt seat 2111. The needle felt seat 2111 has an air inlet connected to the suction port 2123 of the hair-pushing plate 212. The needle plate 211 is snap-connected to the housing 2 of the brush head 21. The actuator 30 is provided on the housing 213 of the brush head 21 and is movable in the direction of the grip 220. The transmission assembly 4 is rotatably connected to the needle felt seat 2111. Optionally, the actuator 30 is a push-twist mechanism. When pushed in the direction of the grip 220, the push-twist mechanism acts on the transmission assembly 4 via a guide structure, thereby moving the hair-pushing plate 212 to the push-out position. The thrust is then released, and the hair-pushing plate 212 returns to its retracted state. Optionally, the actuator 30 is a pull ring, which can be pulled along the axial direction of the grip 220 to expand the hair-pushing plate 212. During normal combing, the pull ring is not pulled. At this time, the combing needle 21121 extends out of the hair-pushing plate 212. The user holds the brush handle 22 to comb the pet's hair. After combing, the pull ring is pulled backward to drive the transmission assembly 4 to rotate through the guide structure, thereby driving the hair-pushing plate 212 to move up and down.

[0080] According to an embodiment of the present disclosure, the cleaning accessory 1 includes a brush handle 22 having a gripping portion 220 and a connection portion 221 for connecting to a vacuum cleaner, and a brush head 21 connected to the brush handle 22. The cleaning accessory 1 can use a brush pusher plate 212 to clean residual dirt on the combing needles 21121 and can remove the residual dirt through a suction port 2123, thereby facilitating self-cleaning of the cleaning accessory 1.

[0081] In conjunction with Figures 12 to 17 , a cleaning accessory 1 according to an embodiment of the present disclosure is shown. The cleaning accessory 1 may include a cleaning head. Specifically, the cleaning head may include: a brush head 21, a bristle-pushing plate 212, and an actuator 30. The cleaning accessory 1 may also include a brush handle 22, which may have a gripping portion and a connector for connecting to a vacuum cleaner; the brush head 21 is connected to the brush handle 22. The cleaning accessory 1 can use the bristle-pushing plate 212 to clean residue from the bristles 21121, and the residue can be sucked away through the suction port 2123, facilitating self-cleaning of the cleaning accessory 1.

[0082] Specifically, the brush head 21 has a suction port 2123, and a combing needle 21121 is provided at the suction port 2123. During the cleaning process, negative pressure can be generated at the suction port 2123 to suck away the dirt. The combing needle 21121 can have the function of a comb or a brush, that is, the combing needle 21121 can be extended into the interior of the object to be cleaned for cleaning, thereby improving the efficiency and effect of cleaning.

[0083] The pusher plate 212 is connected to the brush head 21, and the combing needles 21121 can be extended from the pusher plate 212. The actuator 30 is connected to the pusher plate 212 to drive the pusher plate 212 to move between an extended state and a retracted state. In the retracted state, the combing needles 21121 extend from the pusher plate 212; in the extended state, the combing needles 21121 retract relative to the pusher plate 212. Specifically, as shown in Figure 12, when the pusher plate 212 is in the retracted state, the combing needles 21121 can extend from the pusher plate 212, thereby facilitating the insertion of the combing needles 21121 into the interior of the object to be cleaned. For example, when combing a pet's hair, the combing needles 21121 can be inserted into the pet's hair, thereby combing and cleaning the pet's hair. As shown in Figure 13, when the pushing plate 212 is in the pushing state, the combing needle 21121 retracts relative to the pushing plate 212. At this time, the dirt on the combing needle 21121 can be pushed down by the pushing plate 212 and sucked away under the negative pressure of the suction port 2123, thereby realizing self-cleaning of the combing needle 21121.

[0084] The cleaning accessory 1 according to the embodiment of the present disclosure can use the hair pushing plate 212 to clean the residue on the combing needles 21121, and can suck away the residue through the suction port 2123, so as to facilitate the self-cleaning of the cleaning accessory 1.

[0085] Specifically, the cleaning head is connected to the brush handle 22. The connection can be a split structure docking, that is, the cleaning head and the brush handle 22 are formed separately and then assembled; or it can be an integrated structure, that is, the cleaning head and the brush handle 22 are formed in one piece. The relevant drawings illustrate the cleaning head separately, which does not limit the cleaning head to a separate structure, but is only for the convenience of structural description. During operation, the brush handle 22 can be held by hand to comb the pet hair. The shed pet hair is entangled on the combing needles. When the hair on the combing needles needs to be cleaned, the hair pushing plate 212 is driven out, and the hair pushing plate 212 moves along the combing needles 21121, that is, the hair pushing plate 212 moves outward and the combing needles are in a relatively retracted state, guiding the hair on the combing needles 21121 to the surface of the hair pushing plate 212, and the pet hair is sucked into the dust cylinder of the vacuum cleaner through the suction port on the surface of the hair pushing plate 212.

[0086] In addition, a vent hole 2121 communicating with the suction port 2123 is provided on the hair pushing plate 212, and the combing needles 21121 can pass through the vent hole 2121 in the storage state.

[0087] It should also be noted that, for the sake of simplicity, only one combing needle 21121 is shown in the cleaning attachment 1 in Figures 12 through 18 of the present disclosure. This is merely for ease of understanding and does not reflect the actual state of the product. In some embodiments of the present disclosure, the multiple mounting holes 21122 on the needle felt pad in Figure 18 can all be used to mount combing needles 21121. In actual products, at least a portion of these multiple mounting holes 21122 are mounted with combing needles 21121.

[0088] As shown in FIG. 14 to FIG. 17 , in some embodiments of the present disclosure, the actuator 30 includes an actuating member 32 , which can move in a predetermined direction (refer to the up and down directions in the drawings) to drive the hair pushing plate 212 to be pushed out.

[0089] In some examples, the predetermined direction is toward the grip of the cleaning attachment 1; or the predetermined direction is away from the grip of the cleaning attachment 1. Furthermore, the predetermined direction forms an angle with the axis of the suction port 2123. This allows the actuator 32 to be driven in the gripping direction, thereby driving the hair-pushing plate 212. This facilitates the application of force to the actuator 32, making the use of the cleaning attachment 1 more labor-saving. The grip of the cleaning attachment 1 refers to the portion of the cleaning attachment 1 that is conveniently held for cleaning. FIG. 14 illustrates the grip 220.

[0090] In addition, the cleaning attachment 1 in the present disclosure may include a cleaning head, the aforementioned brush head, the bristle pushing plate and the actuator are combined into a cleaning head, or the cleaning head includes the aforementioned brush head, the bristle pushing plate and the actuator, and the brush handle 22 has a gripping portion.

[0091] In other examples, the predetermined direction may also be defined as the direction of movement of the cleaning attachment (100) or an acute angle with the direction of movement of the cleaning attachment 1. The direction of movement of the cleaning attachment 1 refers to the direction in which the cleaning attachment 1 is driven to move when the user uses the cleaning attachment 1, for example, the direction in which the cleaning attachment combs the pet's hair when the cleaning attachment 1 is used to clean the pet's hair. Of course, these are only some examples of the present disclosure and are not intended to limit the scope of protection of the present disclosure. The grip portion may also be provided on other structures connected to the brush handle, as long as it is convenient for the user to hold and use the brush.

[0092] As shown in Figures 14 to 18, the actuator 30 further includes a transmission member 33, which can be driven by the actuator 32 to press the hair-pushing plate 212 and drive the hair-pushing plate 212 to expand. In other words, the transmission member 33 can convert the driving force in a predetermined direction into the axial movement of the hair-pushing plate 212 along the suction port 2123, which can facilitate the transmission of power and stably transmit the displacement of the actuator 32 to the hair-pushing plate 212, thereby facilitating the self-cleaning of the cleaning accessory 1.

[0093] As shown in FIG18 , one end of the transmission member 33 is rotatably connected to the brush head 21, and the other end is provided with a pressing portion 333. The pressing portion 333 has a guide bevel 3331. The actuator 32 can abut the guide bevel 3331 and press the pressing portion 333 toward the hair-pushing plate 212, thereby driving the pressing portion 333 to press the hair-pushing plate 212. Specifically, during the process of driving the actuator 32, the displacement generated by the actuator 32 is applied to the guide bevel 3331. The guiding action of the guide bevel 3331 transmits the movement of the actuator 32 in the predetermined direction to axial movement along the suction port 2123, thereby driving the hair-pushing plate 212 from a stored state to a pushed-out state, thereby cleaning hair and the like from the combing needles 21121. The rotation of the transmission member 33 ensures stable transmission of displacement, thereby improving the stability of the actuator 30.

[0094] As shown in Figures 15 and 17, in some embodiments of the present disclosure, the brush head 21 has a housing chamber 1102 and an airflow channel 2125. The housing chamber 1102 and the airflow channel 2125 are separated. The transmission member 33 is disposed in the housing chamber 1102, and at least a portion of the actuator 32 is disposed outside the brush head 21. The airflow channel 2125 is connected to the suction port 2123. The actuator 30 can be separated from the airflow channel 2125 to prevent dirt flowing through the airflow channel 2125 from affecting the stable operation of the actuator 30. In addition, disposing a portion of the actuator 30 in the housing chamber 1102 can maintain the stable operation of the actuator 30, while disposing the actuator 32 outside the brush head 21 facilitates manual actuation of the actuator 32, thereby achieving rapid cleaning of the bristles 21121.

[0095] With reference to Figures 15, 17, and 18, in some embodiments, a needle felt seat 2112 is provided around the suction port 2123 of the brush head 21. The hair-pushing plate 212 includes a plate portion 2129 and a second guide portion 215. The plate portion 2129 is stacked on the outer side of the needle felt seat 2112. The second guide portion 215 is connected to the hair-pushing plate 212 and is movably disposed in the needle felt seat 2112 or the suction port 2123 along the axis of the suction port 2123. The actuator 30 can press against the second guide portion 215 to drive the hair-pushing plate 212 to expand. The second guide portion 215 can guide the movement of the hair-pushing plate 212, thereby improving the stability of the movement of the hair-pushing plate 212. In addition, the second guide portion 215 can extend into the aforementioned accommodating chamber 1102 and be pressed and driven by the transmission member 33 located in the accommodating chamber 1102, thereby conveniently driving the hair-pushing plate 212 and improving the stability of the operation of the hair-pushing plate 212.

[0096] As shown in FIG18 , the plate portion 2129 is in the shape of a strip, and a second guide portion 215 is provided at both ends. A slide groove 2126 is provided on the brush head 21 and / or the needle felt pad 2112. Specifically, a slide groove 2126 is provided on the needle felt seat 2112, the needle felt pad 2112 and / or the needle felt cover 2113. The second guide portion 215 is passed through the slide groove 2126 and can slide along the slide groove 2126. The second guide portion 215 may include a first guide plate 2151 and a second guide plate 1222. The first guide plate 2151 and the second guide plate 1222 are arranged at intervals along the length direction of the plate portion 2129, and the brush head 21 is provided with a first groove portion 2126 adapted to the first guide plate 2151. 127 and a second groove portion 2128 adapted to the second guide plate 1222, guide ribs 2153 are provided on the first guide plate 2151 and the second guide plate 1222, wherein the guide rib 2153 on the first guide plate 2151 can be set on the side of the first guide plate 2151 away from the second guide plate 1222, and the guide rib 2153 on the second guide plate 1222 can be said to be more than on the side of the second guide plate 1222 away from the first guide plate 2151, wherein the guide ribs 2153 can be provided on both sides of the first guide plate 2151 along the width direction, and the guide ribs 2153 can be provided on both sides of the second guide plate 1222 along the width direction.

[0097] In some embodiments, the actuator 30 includes a reset element (not shown) connected to the hair-pushing plate 212. The reset element has an elastic force that drives the hair-pushing plate 212 toward the retracted state. The reset element can maintain the hair-pushing plate 212 in the retracted state. In this way, when using the cleaning attachment 1 to comb hair, the actuator 30 does not need to be used, which can save effort during the combing process.

[0098] In some embodiments, in conjunction with Figures 15, 17, and 18, and in conjunction with the above description, a needle felt seat 2112 may be provided on the periphery of the suction port 2123, and the cleaning accessory 1 may further include: a needle felt pad 2112, the needle felt pad 2112 being stacked on the needle felt seat 2112, and the combing needles 21121 being provided on the needle felt pad 2112; and a needle felt cover 2113, the needle felt cover 2113 being connected to the needle felt seat 2112 and cooperating with the needle felt seat 2112 to clamp and position the needle felt pad 2112. The cooperation between the needle felt cover 2113 and the needle felt seat 2112 enables the needle felt pad 2112 to be stably positioned, thereby achieving the positioning of the combing needles 21121 and improving the stability of the combing needles 21121.

[0099] As shown in Figures 12 and 13, the actuator 32 can be arranged on the outside of the brush head 21, for example, on the surface of the outer shell 213 of the brush head 21 or on the surface of the brush handle 22 described below. A rotating assembly is provided in the brush head 21, and the rotating assembly includes a transmission member 33, a pushing member and a reset member; the reset member can be provided between the brush head 21 and the pushing member, and a slide groove 2126 is provided on the brush head 21, and a second guide portion 215 is provided on the back of the pushing plate 212, and the second guide portion 215 can slide in the slide groove 2126.

[0100] In some embodiments, the combing needles 21121 are flexibly connected to the needle felt pad 2112. The combing needles 21121 can be fixed to the needle felt pad 2112, which is made of rubber. A retaining structure is used at the fixed end of the combing needles 21121 to secure the combing needles to the needle felt pad 2112. Specifically, the combing needles 21121 have a fixed end and a free end. The fixed end of the combing needles 21121 is provided with a first positioning portion and a second positioning portion. The first positioning portion and the second positioning portion can be spaced apart along the length of the combing needles 21121 and located on either side of the needle felt pad 2112, respectively, to achieve stable cooperation between the combing needles 21121 and the needle felt pad 2112. The first positioning portion is further away from the free end than the second positioning portion, while the second positioning portion is closer to the free end than the first positioning portion. A surface of the second positioning portion facing away from the first positioning portion is configured as an inclined surface that gradually tilts toward the first positioning portion in a direction away from the axis of the combing needle 21121.

[0101] The combing needles 21121 and the fixed end (e.g., the end that contacts the pet) are spherical. Since the connection between the combing needles 21121 and the needle felt pad 2112 is non-rigid, the combing needles 21121 can tilt at a certain angle when contacting the pet. Moreover, the spherical end of the contact end does not exert excessive force on the pet, thus avoiding the pet's sudden overreaction.

[0102] In some embodiments, the combing needles 21121 and the brush head 21 are relatively stationary, and the hair pushing plate 212 and the brush head 21 are relatively movable.

[0103] In combination with the above-mentioned embodiment, the brush head 21 of the cleaning head can be connected to the brush handle 22, the brush handle 22 can have a gripping portion and a connector for connecting to the vacuum cleaner, the brush head 21 has a accommodating cavity 1102, and a rotating component is provided in the accommodating cavity 1102. The brush head 21 is provided with a combing needle 21121 plate and a hair pushing plate 212. The combing needle 21121 plate is fixed to the brush head 21, and the hair pushing plate 212 can move relative to the brush head 21. Specifically, the shell of the cleaning head includes an outer shell 213 and an inner joint, and the inner joint can be located inside the handle; the combing needle 21121 plate includes a needle felt pad 2112, a needle felt cover 2113 and a combing needle 21121, and a convex point is set at the end of the combing needle 21121 (for example, the combing needle 21121 includes a needle-shaped portion and a convex point, and the convex point can be set to a sphere with a radial size larger than the needle-shaped portion), which has the function of massaging and removing hair; the actuator 30 may include a transmission member 33 and an actuator 32, wherein the actuator 32 is used for manual drive, and the transmission member 33 is used to transmit the displacement and power of the actuator 32 to the hair pushing plate 212. In addition, the actuator 30 may also include a reset member, which is used to reset the hair pushing plate 212, and is used to maintain the hair pushing plate 212 in a retracted state without the need for external force during use, so that the cleaning head is labor-saving to use.

[0104] 15 , 17 , and 18 , in some embodiments, the brush head 21 may include an outer shell 213 and an inner shell 214, with an accommodating chamber 1102 formed between the outer shell 213 and the inner shell 214. An airflow channel 2125 is formed in the inner shell 214, and a suction port 2123 is provided. The suction port 2123 communicates with the airflow channel 2125. The inner shell 214 may include a needle felt seat 2112 and a pipe 20. The needle felt seat 2112 is provided with a first opening. One end of the pipe 20 is connected to the needle felt seat 2112 and communicates with the first opening. The needle felt seat 2112 covers the outer shell 213, and an accommodating chamber 1102 is formed between the needle felt seat 2112 and the outer shell 213. The pipe 20 passes through the accommodating chamber 1102.

[0105] The cleaning accessory 1 also includes a needle felt pad 2112, a needle felt cover 2113 and a combing needle 21121, wherein the needle felt pad 2112 is stacked on the needle felt seat 2112 and is provided with a second opening opposite to the suction port 2123; the needle felt cover 2113 is stacked on the needle felt pad 2112 and is provided with a third opening opposite to the second opening, the periphery of the needle felt cover 2113 is snap-connected with the needle felt seat 2112 to clamp and position the needle felt pad 2112, and the combing needle 21121 on the needle felt pad 2112 passes through the needle felt cover 2113; the hair pushing plate 212 is stacked on the outside of the needle felt cover 2113, and the hair pushing plate 212 is provided with a fourth opening opposite to the third opening, and the hair pushing plate 212 is provided with a long strip of ventilation holes 2121, and the combing needles 21121 extend from the ventilation holes 2121. Among them, the periphery of the suction port 2123 is passed through or sleeved on the second opening, and the periphery of the fourth opening is connected with a sleeve, which is passed through or sleeved in the suction port 2123, and can provide guidance for the movement of the pushing plate 212 between the pushing state and the storage state.

[0106] The actuator 30 includes an actuating member 32, a slider 34, a transmission member 33, and a reset member (not shown). The actuating member 32 is disposed on the housing 213 and can be pushed in a direction away from the grip portion. The actuating member 32 is exposed on the outer surface of the housing 213. The slider 34 is connected to the actuating member 32 and is slidably disposed on the inner side of the housing 213. The slider 34 slides with the actuating member 32. One end of the transmission member 33 is rotatably connected to the brush head 21. A fixing seat can be set on the outer shell 213 and the inner shell 214, and the rotating shaft of the positioning transmission member 33 is clamped by the fixing seat of the inner shell 214 and the fixing seat of the outer shell 213. The transmission member 33 can be set to include a first branch 331, a second branch 332 and a pressing portion 333, one end of the first branch 331 is hinged to the brush head 21, one end of the second branch 332 is hinged to the brush head 21, the pressing portion 333 connects the other end of the first branch 331 and the other end of the second branch 332, and a guide slope 3331 is provided on the pressing portion 333.

[0107] During the use of the cleaning attachment 1, the elastic force of the reset member drives the hair pushing plate 212 into the storage state, so that there is no need to apply force to the hair pushing plate 212, and the storage state of the hair pushing plate 212 can be maintained, and the combing needle 21121 can be extended from the hair pushing plate 212 for combing hair.

[0108] In combination with the foregoing embodiments, the present disclosure provides some specific embodiments of the actuator 30 below, which is not intended to limit the scope of protection of the present disclosure.

[0109] As shown in FIG. 12 to FIG. 18 , in some embodiments of the present disclosure, the actuator 32 may be a push knob, which may be pushed in a direction away from the grip portion to drive the push plate 212 to unfold.

[0110] When the combing needles 21121 need to be cleaned, the push knob can be pushed in a direction away from the gripping portion. The pressing portion 333 is provided with a guide bevel 3331, which faces the gripping portion and is opposite to the push knob. When the push knob is pushed, the push knob contacts and presses against the guide bevel 3331, driving the pressing portion 333 to move away from the gripping portion and toward the hair-pushing plate 212. In addition, the second guide portion 215 of the hair-pushing plate 212 is opposite to the pressing portion 333. When the pressing portion 333 moves toward the hair-pushing plate 212, the pressing portion 333 applies force to the pressing portion 333, pressing the hair-pushing plate 212, thereby moving the hair-pushing plate 212 to the ejection position. Subsequently, under the elastic force of the reset member, the hair-pushing plate 212 is reset to the storage state.

[0111] As shown in FIG. 19 , in some other embodiments of the present disclosure, the actuator 32 may be a pull ring, which may be pulled toward the grip portion to drive the hair-pushing plate 212 to unfold.

[0112] Specifically, during normal combing, the pull ring is not pulled, and the combing needle 21121 extends out of the hair-pushing plate 212. The user holds the brush handle 22 to comb the pet's hair; after combing, the pull ring is pulled backward, and the slider 34 is driven to move. The guide slope 3331 on the pressing part 333 is facing away from the holding part and opposite to the slider 34. When the pull ring is pulled backward, the slider 34 contacts and presses the guide slope 3331, driving the pressing part 333 to move toward the holding part and toward the hair-pushing plate 212. In addition, the second guide portion 215 of the pushing plate 212 is arranged opposite to the pressing portion 333. When the pressing portion 333 moves toward the pushing plate 212, the pressing portion 333 will apply force to the pressing portion 333 to press the pushing plate 212, thereby moving the pushing plate 212 to the pushing position; the pushing plate 212 moves to clean the combing needles 21121, and the garbage cleaned on the combing needles 21121 is sucked into the dust bin of the vacuum cleaner.
