Description

Technical Field

[0001] This utility model relates to the field of cleaning appliance technology, specifically to a cleaning head. Background Technology

[0002] Currently, glass cleaning typically requires both a wiping board and a scraper. The wiping board is used to wipe the glass, and then the scraper is used to remove water stains. Some glass cleaners also have both a wiping board and a scraper, allowing users to wipe and scrape the glass in one pass. However, glass cleaning requires repeated wiping, and if the scraper removes all the water stains with each wipe, it will affect the wiping effect. Utility Model Content

[0003] In view of this, the present invention provides a cleaning head to solve the problem that when a glass wiper is equipped with both a wiping plate and a scraper, the scraper will scrape away water stains with each wiping operation, thus affecting the wiping effect of the wiping plate.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0079] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0080] The following is combined Figures 1-11 The following describes embodiments of the present invention.

[0081] According to an embodiment of the present invention, a cleaning head is provided, such as... Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, it includes: a cleaning plate 1, a scraper 2, and a locking assembly.

[0082] The cleaning plate 1 has a cleaning surface 101 and a side wall 102 on its side; the scraper 2 is movably disposed on the side wall 102 and has a first position and a second position; when the scraper 2 is in the first position, the scraper 2 protrudes from the cleaning surface 101; when the scraper 2 is in the second position, the scraper 2 does not protrude from the cleaning surface 101; a locking assembly is disposed between the cleaning plate 1 and the scraper 2, and the locking assembly is used to fix the scraper 2 in the first position or the second position.

[0083] In the above embodiment, the scraper 2 is directly disposed on the side wall 102 of the cleaning plate 1. When adjusting the position of the scraper 2, the relative position of the scraper strip 201 of the scraper 2 and the cleaning surface 101 of the cleaning plate 1 can be seen intuitively, making the adjustment more accurate and quick. It is especially suitable for scenarios that require frequent alternation of wiping and squeegee functions. At the same time, it reduces the leverage effect caused by the scraper 2 being connected to the rod of the cleaning head, ensuring uniform pressure on the wiping surface and preventing the cleaning head from shaking. Furthermore, the installation position of the scraper 2 does not affect the user's operation of the rod connected to the cleaning head, making it convenient for the user to operate and ensuring the wiping effect.

[0084] Furthermore, a cleaning plate 1 is provided on the cleaning head, and a scraper 2 that can move relative to the side wall 102 of the cleaning plate 1 is provided, so that the scraper 2 has a first position and a second position that can be fixed by a locking component; when the cleaning head needs to wipe repeatedly, the scraper 2 is fixed in the second position that does not protrude from the cleaning surface 101, so as to avoid the scraper 2 contacting the surface to be cleaned and scraping away water stains; when the cleaning head needs to scrape water, the scraper 2 is fixed in the first position that protrudes from the cleaning surface 101, so that the scraper 2 contacts the surface to be cleaned to scrape water while the cleaning plate 1 is wiping; thereby ensuring the wiping effect of the cleaning head.

[0085] Specifically, the cleaning head is designed as a glass wiper; the cleaning head housing can be hinged to a rod for easy gripping. The cleaning plate 1 within the cleaning head has a plate-like structure, with a wiping cloth on its bottom surface forming a cleaning surface 101. The cleaning plate 1 has a side wall 102, which provides an mounting position for the scraper 2. The scraper 2 within the cleaning head has a strip-like structure and is constructed as a scraper. A scraper strip 201 is provided at the bottom of the scraper 2 for wiping water. The scraper 2 is directly mounted on the side wall 102 of the cleaning plate 1. When adjusting the position of the scraper 2, the relative position of the scraper strip 201 and the cleaning surface 101 of the cleaning plate 1 can be clearly seen, making adjustments more accurate and faster, especially suitable for scenarios requiring frequent alternation between wiping and wiping functions. Meanwhile, if the scraper 2 is connected to the rod of the cleaning head instead of the side wall 102 of the cleaning plate 1, it needs to be extended to the cleaning surface 101 of the cleaning plate 1 via a connector connected to the rod. This may create a leverage effect due to the length of the connector, resulting in unstable force on the scraper 2 and incomplete wiping. However, if the scraper 2 is directly set on the side wall 102 of the cleaning plate 1, the leverage effect is reduced. When wiping, the scraper 201 can fit tightly against the surface to be wiped, resulting in uniform pressure on the surface to be wiped and less shaking of the cleaning head. Furthermore, if the scraper 2 is connected to the rod of the cleaning head instead of the side wall 102 of the cleaning plate 1, it needs to be extended to the cleaning surface 101 of the cleaning plate 1 via a connector connected to the rod. This connector may affect the user's grip or operation of the rod. However, if the scraper 2 is directly set on the side wall 102 of the cleaning plate 1, it will not affect the user's operation of the rod at all.

[0086] Furthermore, the scraper 2 is movably disposed on the side wall 102 so that the scraper 2 can switch between a first position and a second position, thereby causing the scraper 2 to protrude or not protrude from the cleaning surface 101. In this embodiment, the cleaning head is used on the surface to be wiped in a horizontal position as an example. When the scraper 2 is in the first position, the scraper 2 protrudes from the cleaning surface 101, that is, the lowest position of the scraper strip 201 of the scraper 2 is lower than the lowest position of the cleaning surface 101, that is, the scraper strip 201 of the scraper 2 is located below the horizontal plane of the cleaning surface 101. At this time, the cleaning plate 1 wipes while the scraper 2 can also perform water squeezing. When the scraper 2 is in the second position, the scraper 2 does not protrude from the cleaning surface 101, that is, the lowest position of the scraper strip 201 of the scraper 2 is not lower than the lowest position of the cleaning surface 101, that is, the scraper strip 201 of the scraper 2 is located above the horizontal plane of the cleaning surface 101. At this time, the cleaning plate 1 wipes while the scraper 2 cannot perform water squeezing.

[0087] The following describes examples of two cleaning heads.

[0088] For the first embodiment of the cleaning head, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in some embodiments, the scraper 2 is movably disposed on the side wall 102, and the scraper 2 translates when switching between a first position and a second position.

[0089] In the above embodiments, the scraper 2 is translated relative to the side wall 102 of the cleaning plate 1 to switch the scraper 2 between the first position and the second position, which is convenient, quick and easy to operate.

[0090] Specifically, when the scraper 2 is in the first position, the scraper blade 201 of the scraper 2 is below the horizontal plane of the cleaning surface 101; when the scraper 2 is in the second position, the scraper blade 201 of the scraper 2 is above the horizontal plane of the cleaning surface 101 or flush with the horizontal plane of the cleaning surface 101. When the scraper 2 switches from the first position to the second position, the locking component is first unlocked, and then the scraper 2 is moved upward so that the scraper blade 201 moves from below the horizontal plane of the cleaning surface 101 to above the horizontal plane of the cleaning surface 101 or flush with the horizontal plane of the cleaning surface 101, and then the locking component is reset; the reverse is also true.

[0091] Furthermore, a movable connection is formed between the squeegee 2 and the side wall 102 of the cleaning plate 1. When the user needs the cleaning head to wipe repeatedly, the squeegee 2 is moved from the first position to the second position and fixed in position using the locking component; when the user needs the cleaning head to wring out water, the squeegee 2 is moved from the second position to the first position and fixed in position using the locking component as well.

[0092] In some embodiments, the locking component includes: a first locking structure 3, a first mounting position, and a second mounting position.

[0093] The first locking structure 3 is disposed on the cleaning plate 1; the first mounting position and the second mounting position are disposed on the scraper 2 and are respectively used to cooperate with the first locking structure 3; when the first locking structure 3 cooperates with the first mounting position, the scraper 2 is in the first position; when the first locking structure 3 cooperates with the second mounting position, the scraper 2 is in the second position.

[0094] In the above embodiments, in the first embodiment of the cleaning head, the locking component achieves the fixation of the scraper 2 at the first or second position by cooperating with the first locking structure 3 provided on the cleaning plate 1 and the first and second mounting positions provided on the scraper 2 respectively.

[0095] Specifically, the scraper 2 has a strip-shaped structure, and the first mounting position and the second mounting position are located on the side of the scraper 2. This embodiment does not limit the specific cooperation method between the first locking structure 3 and the first mounting position. In one embodiment, the first locking structure 3 has a protrusion, and the first mounting position has a groove; the protrusion and the groove limit the scraper 2 to the side wall 102 of the cleaning plate 1. In another embodiment, the first locking structure 3 has a buckle, and the first mounting position has a latch; the buckle and the latch engage to fix the scraper 2 to the side wall 102 of the cleaning plate 1.

[0096] In some embodiments, the first locking structure 3 includes a fixing member 301 that can extend or retract relative to the side wall 102, a first mounting position being a first fixing hole 202, and a second mounting position being a second fixing hole 203; the fixing member 301 extending out of the side wall 102 can engage with the first fixing hole 202 or the second fixing hole 203 to fix the scraper 2 in a first position or a second position; the fixing member 301 retracting out of the side wall 102 can disengage from the first fixing hole 202 or the second fixing hole 203 so that the scraper 2 can switch between the first position and the second position.

[0097] In the above embodiment, the fixing member 301 is used to limit and engage with the first fixing hole 202 and the second fixing hole 203 to fix the scraping member 2 to the side wall 102 of the cleaning plate 1 at the first or second position.

[0098] Specifically, the fixing member 301 is a block-shaped structure that can extend or retract relative to the side wall 102, and the first fixing hole 202 and the second fixing hole 203 are slots on the side of the scraper 2 that are shaped to conform to the block-shaped structure. When the block-shaped structure is engaged with the slot, it can engage and limit the scraper 2.

[0099] Furthermore, specific embodiments of the extension or retraction of the fastener 301 relative to the side wall 102 include, but are not limited to, setting an electrically controlled transmission structure to connect the fastener 301 and driving it through circuit control, setting a mechanical transmission structure to connect the fastener 301 and driving it manually by the user, etc.

[0100] In some embodiments, at least two fasteners 301 are provided along the length of the sidewall 102, and at least two sets of first fixing holes 202 and second fixing holes 203 are provided along the length of the scraper 2.

[0101] In the above embodiment, multiple fasteners 301 are provided to align and cooperate with multiple sets of first fixing holes 202 and second fixing holes 203 to improve the stability of the scraper 2 fixed to the side wall 102 of the cleaning plate 1 and prevent the scraper 2 from falling off.

[0102] Specifically, in this embodiment, four fixing members 301 are provided along the length direction of the side wall 102, and at least four sets of first fixing holes 202 and second fixing holes 203 are provided along the length direction of the scraping member 2. The four fixing members 301 and the four first fixing holes 202 and second fixing holes 203 are symmetrically arranged on the left and right sides of the cleaning head.

[0103] In some embodiments, the first locking structure 3 further includes a driving member 302 that is tractively connected to the fixing member 301, the driving member 302 being used to drive the fixing member 301 to extend or retract from the side wall 102.

[0104] In the above embodiment, the first locking structure 3 is provided with a driving member 302 that is connected to the fixing member 301 in a transmission manner, so that the user can manually fix the member 301 to extend or retract the side wall 102 through the driving member 302.

[0105] Specifically, the drive component 302 is connected to the fixing component 301 and extends out of the cleaning plate 1 so that the user can manually drive the drive component 302.

[0106] In some embodiments, a receiving cavity is formed inside the cleaning plate 1, and the first locking structure 3 further includes a first main body 303, which is fixedly connected to a fixing member 301 and a driving member 302. The cleaning plate 1 is provided with a relief groove 103 communicating with the receiving cavity. The driving member 302 extends out of the receiving cavity from the relief groove 103 and can move in the relief groove 103 so as to drive the fixing member 301 to extend or retract from the side wall 102 through the first main body 303.

[0107] In the above embodiment, the accommodating cavity inside the cleaning plate 1 provides an installation position for the first locking structure 3; the first main body 303 is fixedly connected to the fixing member 301 and the driving member 302 so that the driving member 302 can drive the fixing member 301 to extend or retract from the side wall 102.

[0108] Specifically, the cleaning plate 1 forms an intermediate receiving cavity through the housing and the base plate. The housing has a clearance hole for the protruding fastener 301. During assembly, the first locking structure 3 is placed inside the housing, aligning or extending the fastener 301 through the clearance hole. Simultaneously, the driving member 302 extends through the clearance groove 103 at the top of the housing, and then the base plate is assembled to the housing. The bottom surface of the base plate is provided with a wiping cloth to form a cleaning surface 101.

[0109] Furthermore, the clearance groove 103 is configured as a strip groove so that the drive member 302 can move in the clearance groove 103 in the direction of extending or retracting the side wall 102 along the fixing member 301, so as to realize the movement adjustment of the drive member 302 on the fixing member 301.

[0110] Furthermore, in this embodiment, the driving component 302 is fixedly connected to the first main body 303 by screws or other connecting components; the driving component 302 is integrally formed into the first main body 303. As an alternative implementation, the driving component 302 is integrally formed into the first main body 303.

[0111] In some embodiments, the locking assembly further includes a first reset member 4 disposed inside the cleaning plate 1. The first reset member 4 abuts between the first main body 303 and the inner wall of the cleaning plate 1, and is used to push the first main body 303 to drive the fixing member 301 to reset.

[0112] In the above embodiment, a first reset member 4 is provided between the first main body 303 and the inner wall of the cleaning plate 1 to drive the fixing member 301 to reset, which facilitates user operation; at the same time, it also improves the assembly stability of the scraping member 2.

[0113] Specifically, when it is necessary to switch the scraper 2 between the first position and the second position, the user manually pulls the drive component 302 back and maintains force on the drive component 302. The drive component 302 drives the fixing component 301 to retract into the side wall 102 through the first main body component 303. At this time, the first reset component 4 is compressed. The user moves and adjusts the scraper 2 to the desired position, and then releases the drive component 302. The first main body component 303 drives the fixing component 301 to reset under the extension action of the first reset component 4. At the same time, the first reset component 4 is still in a compressed state after resetting. The first reset component 4 continuously applies force to the fixing component 301 through the first main body component 303 to ensure that the fixing component 301 is stably abutting against the first fixing hole 202 or the second fixing hole 203, thereby improving the assembly stability of the scraper 2.

[0114] Furthermore, the first reset element 4 is configured as a spring.

[0115] In some embodiments, the first position and the second position are distributed along the thickness direction of the scraper 2.

[0116] In the above embodiment, the first position and the second position are distributed along the thickness direction of the scraper 2 so that the user can adjust the position of the scraper 2.

[0117] Specifically, in this embodiment, the cleaning head is used on the surface to be wiped in a horizontal position as an example. When the scraper 2 is in the first position or the second position, the scraper 2 is at different heights on the side wall 102 of the cleaning plate 1.

[0118] In some embodiments, when the locking component includes a first mounting position and a second mounting position, the first mounting position and the second mounting position are distributed along the thickness direction of the scraper 2.

[0119] In the above embodiment, the first mounting position and the second mounting position are distributed along the thickness direction of the scraper 2, so that when the scraper 2 is fixed in the first position, it protrudes from the cleaning surface 101, and when the scraper 2 is fixed in the second position, it does not protrude from the cleaning surface 101.

[0120] Specifically, the scraper 2 has a strip-shaped structure, taking the use of the cleaning head on the surface to be wiped in a horizontal position as an example. The side height of the scraper 2 is the thickness of the scraper 2. The scraper 2 is provided with a first mounting position and a second mounting position, which are located at different heights on the side of the scraper 2.

[0121] In some embodiments, one of the sidewall 102 and the scraper 2 is provided with a groove 104, and the other is provided with a slider 204. When the scraper 2 switches between a first position and a second position, the slider 204 can slide relative to the groove 104.

[0122] In the above embodiment, by setting the slider 204 to slide in the groove 104, the smoothness and accuracy of the scraper 2 when switching between the first position and the second position are improved.

[0123] Specifically, the side wall 102 of the cleaning plate 1, i.e., the housing of the cleaning plate 1, is provided with a groove 104, and the side of the scraper 2 is provided with a slider 204. In this embodiment, the groove 104 and the slider 204 form four sets of guiding sliding mating structures. The mating structures formed by the four grooves 104 and the four sliders 204 are symmetrically arranged on the left and right sides of the cleaning head.

[0124] Furthermore, in this embodiment, the slider 204 is integrally formed on the side of the scraper 2. As an alternative implementation, the slider 204 is fixedly connected to the side of the scraper 2 by a connector.

[0125] In some embodiments, the slider 204 is provided with a locking block 205, which abuts against the side of the slide groove 104 to restrict the slider 204 from disengaging from the slide groove 104; the slide groove 104 is an open groove, and the slider 204 can disengage from the slide groove 104 along the opening position of the open groove so that the scraper 2 disengages from the cleaning plate 1.

[0126] In the above embodiment, the locking block 205 provided on the slider 204 abuts against the side of the slide groove 104 to prevent the scraper 2 from falling off. The slide groove 104 is an open groove so that the scraper 2 can be detached from the cleaning plate 1, so that the scraper 2 can be used alone.

[0127] Specifically, the end face of the locking block 205 is larger than the end face of the slider 204. After the scraper 2 is assembled, the locking block 205 abuts against the side of the slide groove 104, that is, the inner wall of the cleaning plate 1, to prevent the slider 204 from disengaging from the slide groove 104. In this embodiment, only the two middle sliders 204 are provided with locking blocks 205 integrally formed on the sliders 204.

[0128] Regarding the second embodiment of the cleaning head, as follows: Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, in some embodiments, the scraper 2 is rotatably disposed on the side wall 102, and the scraper 2 rotates relative to the cleaning plate 1 when switching between a first position and a second position.

[0129] In the above embodiment, the scraper 2 is rotated relative to the side wall 102 of the cleaning plate 1 to switch the scraper 2 between the first position and the second position, which is convenient, quick and easy to operate.

[0130] Specifically, when the scraper 2 is in the first position, the scraper blade 201 of the scraper 2 is below the horizontal plane of the cleaning surface 101, and the scraper blade 201 is set downwards. When the scraper 2 is in the second position, the scraper blade 201 of the scraper 2 is above the horizontal plane of the cleaning surface 101, and the scraper blade 201 is set upwards. When the scraper 2 switches from the first position to the second position, the locking component is first unlocked, and then the scraper 2 is rotated so that the scraper blade 201 rotates from the downward position to the upward position, so that the scraper blade 201 rotates from below the horizontal plane of the cleaning surface 101 to above the horizontal plane of the cleaning surface 101, and then the locking component is reset; the reverse is also true.

[0131] Furthermore, a rotatable connection is formed between the squeegee 2 and the side wall 102 of the cleaning plate 1. When the user needs the cleaning head to wipe repeatedly, the squeegee 2 is rotated from the first position to the second position and fixed in position using the locking component; when the user needs the cleaning head to wring out water, the squeegee 2 is rotated from the second position to the first position and fixed in position using the locking component as well.

[0132] Furthermore, the scraper 2 is directly rotatably connected to the side wall 102 of the cleaning plate 1, so that the scraper 2 can rotate relative to the cleaning plate 1. Alternatively, the scraper 2 is rotatably assembled to the side wall 102 of the cleaning plate 1, so that the scraper 2 can rotate relative to the cleaning plate 1.

[0133] In some embodiments, the locking component includes: a mounting post 206, a mounting hole 105, a second locking structure 5, and a limiting hole 106.

[0134] Mounting post 206 is provided in one of the scraper 2 and side wall 102; mounting hole 105 is provided in the other of the scraper 2 and side wall 102, and mounting hole 105 cooperates with the wall surface of mounting post 206 to restrict the rotation of scraper 2 relative to cleaning plate 1; second locking structure 5 is provided in one of the scraper 2 and side wall 102; limiting hole 106 is provided in the other of the scraper 2 and side wall 102, and second locking structure 5 cooperates with limiting hole 106 to restrict scraper 2 from moving relative to cleaning plate 1 along the installation direction.

[0135] In the above embodiment, the scraper 2 is restricted from rotating relative to the cleaning plate 1 by the mounting hole 105 engaging with the wall of the mounting post 206, and the scraper 2 is restricted from moving relative to the cleaning plate 1 by the second locking structure 5 engaging with the limiting hole 106, thereby achieving position adjustment and stable assembly of the scraper 2 on the side wall 102 of the cleaning plate 1.

[0136] Specifically, a mounting post 206 is provided on the scraper 2, and a mounting hole 105 is provided on the side wall 102 of the cleaning plate 1; a second locking structure 5 is provided on the scraper 2, and a limiting hole 106 is provided on the side wall 102 of the cleaning plate 1. In this embodiment, the scraper 2 and the side wall 102 of the cleaning plate 1 are rotatably assembled so that the scraper 2 can rotate relative to the cleaning plate 1. Specifically, when the mounting hole 105 and the mounting post 206 are disengaged, the scraper 2 and the side wall 102 of the cleaning plate 1 can rotate to adjust their position; when the mounting hole 105 and the mounting post 206 are assembled, the rotation of the scraper 2 relative to the cleaning plate 1 is restricted.

[0137] Furthermore, three mounting holes 105 are provided along the length of the side wall 102 of the cleaning plate 1, and three mounting posts 206 are provided along the length of the scraper 2, with the two being aligned. The mounting holes 105 and mounting posts 206 on both sides are symmetrically arranged on the left and right sides of the cleaning head, while the mounting holes 105 and mounting posts 206 in the middle are located in the center of the cleaning head.

[0138] In some embodiments, the second locking structure 5 includes a barb 501 that engages with a limiting hole 106. The limiting hole 106 includes a first limiting edge 1061 and a second limiting edge 1062 disposed opposite to each other. When the scraper 2 is in the first position, the barb 501 engages with the first limiting edge 1061 to restrict the scraper 2 from moving relative to the cleaning plate 1 along the installation direction. When the scraper 2 is in the second position, the barb 501 engages with the second limiting edge 1062 to restrict the scraper 2 from moving relative to the cleaning plate 1 along the installation direction.

[0139] In the above embodiment, the second locking structure 5 is engaged with the first limiting edge 1061 or the second limiting edge 1062 of the limiting hole 106 by the barb 501, thereby fixing the position of the scraping member 2 in the first position or the second position.

[0140] Specifically, in this embodiment, the cleaning head is used on a horizontal surface to be wiped as an example. The barb 501 on the second locking structure 5 is set upward; among the first limiting edge 1061 and the second limiting edge 1062 that are oppositely arranged in the limiting hole 106, the first limiting edge 1061 is located at the upper side edge of the limiting hole 106, and the second limiting edge 1062 is located at the lower side edge of the limiting hole 106.

[0141] In some embodiments, the second locking structure 5 further includes a second main body 502, which is fixedly connected with a barb 501; the second main body 502 is pressably disposed on the scraper 2, and when the second main body 502 is pressed down, it causes the barb 501 to disengage from the first limiting edge 1061 or the second limiting edge 1062, so that the scraper 2 can switch between the first position and the second position.

[0142] In the above embodiment, the second locking structure 5 is pressably disposed on the scraper 2 by the second main body 502, so that the user can move the barb 501 by pressing the second main body 502, thereby causing the barb 501 to disengage from the first limiting edge 1061 or the second limiting edge 1062.

[0143] Specifically, the scraper 2 is provided with a guide post 207, and the second main body 502 is provided with a guide groove 503 that is slidably connected to the guide post 207. The second main body 502 and the scraper 2 are aligned and installed through the guide post 207 and the scraper 2.

[0144] Furthermore, a recess is provided in the middle of the scraper 2, and two guide posts 207 are located in the recess. The second locking structure 5 is embedded in the recess. When the user presses the second locking structure 5, the second main body 502 moves downward in the recess.

[0145] In some embodiments, the locking assembly further includes a second reset member 6, which abuts between the second body member 502 and the scraper member 2, for pushing the second body member 502 to drive the barb 501 to reset.

[0146] In the above embodiment, a second reset member 6 is provided between the second main body 502 and the scraping member 2 to drive the barb 501 to reset, which facilitates user operation.

[0147] Specifically, when it is necessary to switch the scraper 2 between the first position and the second position, the user manually presses the second main body 502 of the second locking structure 5 and maintains force on the second main body 502. The second main body 502 drives the barb 501 to disengage from the first limiting edge 1061. At this time, the second reset member 6 is compressed. The user rotates and adjusts the scraper 2 to the desired position, and then releases the second main body 502. Under the extension action of the second reset member 6, the second main body 502 drives the barb 501 to reset, so that the barb 501 engages with the second limiting edge 1062 which is opposite to the first limiting edge 1061.

[0148] Furthermore, there are two second reset members 6, which are respectively fitted onto the two guide posts 207.

[0149] Furthermore, the second reset element 6 is configured as a spring.

[0150] In both embodiments of the cleaning head, the cleaning plate 1 and the scraper 2 are detachably connected.

[0151] In the above embodiments, the cleaning plate 1 and the squeegee 2 are detachably connected so that the squeegee 2 can be disassembled for squeegeeing alone, or the cleaning plate 1 can be used for wiping alone.

[0152] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
