[0066] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0067] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0068] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. 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.
[0069] 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.
[0070] The following is combined Figures 1-13 This describes embodiments of the present invention. The first direction is the width direction of the cleaning head 1, and the second direction is the length direction of the cleaning head 1. A and / or B include the following types: firstly, only A; secondly, only B; and thirdly, both A and B are present.
[0071] According to an embodiment of this utility model, a cleaning tool is provided, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: a cleaning head 1, a hand handle 2, a first rotating shaft, and a limiting block 3.
[0072] The handle 2 is rotatably connected to the cleaning head 1 via a first pivot, so that the handle 2 can swing relative to the cleaning head 1 in a first direction to change the angle between the handle 2 and the cleaning head 1; the limiting block 3 is detachably disposed between the cleaning head 1 and the handle 2, and the limiting block 3 has a first installation position and a second installation position between the cleaning head 1 and the handle 2; when the limiting block 3 is installed in the first installation position, the cleaning head 1 and the handle 2 are at a first angle; when the limiting block 3 is installed in the second installation position, the cleaning head 1 and the handle 2 are at a second angle.
[0073] In the above embodiment, the handheld lever 2 is rotatably connected to the cleaning head 1 via the first rotating shaft, and a detachable limiting block 3 is provided between the cleaning head 1 and the handheld lever 2. The limiting block 3 limits the setting angle between the cleaning head 1 and the handheld lever 2, so that when the limiting block 3 is installed in different installation positions, the cleaning head 1 and the handheld lever 2 have different angles and form a stable positional relationship, thereby ensuring that the cleaning head 1 and the handheld lever 2 will not swing relative to each other when the user uses it.
[0074] In addition, by changing the installation position of the limiting block 3, the cleaning head 1 and the handheld rod 2 can be stabilized at different angles, which is simple in structure and low in manufacturing cost.
[0075] Specifically, the cleaning tool in this embodiment can be a broom, floor scrubber, or other cleaning tool with a handle 2. The extension of the handle 2 facilitates cleaning operations for the mop head, floor scrubber head, etc., which serve as the cleaning head 1. The limiting block 3, as a limiting component detachably disposed between the cleaning head 1 and the handle 2, can be detachably installed between the cleaning head 1 and the handle 2 when the cleaning head 1 and the handle 2 are rotated to a certain position via the first pivot. It limits the existing position between the cleaning head 1 and the handle 2, preventing relative rotation between the cleaning head 1 and the handle 2 during use, thereby achieving the purpose of relatively fixing the position between the cleaning head 1 and the handle 2.
[0076] In some embodiments, such as Figure 2 , Figure 3 As shown, when the cleaning head 1 and the handheld handle 2 are at a first angle, the handheld handle 2 is arranged perpendicular to the first direction; when the cleaning head 1 and the handheld handle 2 are at a second angle, the handheld handle 2 is offset to the side of the cleaning head 1 along the first direction; or, when the cleaning head 1 and the handheld handle 2 are at a first angle, the handheld handle 2 is offset to one side of the cleaning head 1 along the first direction; when the cleaning head 1 and the handheld handle 2 are at a second angle, the handheld handle 2 is offset to the other side of the cleaning head 1 along the first direction.
[0077] In the above embodiment, by setting the limiting block 3, the hand handle 2 can maintain multiple stable setting angles in the vertical direction or side of the cleaning head 1, so that the user can use the cleaning tool in a suitable posture.
[0078] Specifically, in this embodiment, the angle between the cleaning head 1 and the handheld lever 2 refers to the angle formed by taking the middle surface of the cleaning head 1 along the second direction as the basis, the cleaning head 1 having two sides on both sides of the middle surface, and the handheld lever 2 being able to swing relative to the cleaning head 1 along the first direction on the extended surface of the middle surface to adjust its position, forming a corresponding angle between the centerline of the middle surface of the cleaning head 1 and the axis of the handheld lever 2.
[0079] Furthermore, this embodiment does not limit the specific angle values between the cleaning head 1 and the handheld handle 2 at the first and second angles. The first and second angles can be 180°, 150°, 120°, etc.
[0080] Furthermore, when the cleaning head 1 and the handle 2 are at a 180° angle, the handle 2 is perpendicular to the first direction, and the cleaning head 1 and the handle 2 are collinear. This facilitates sweeping for cleaning tools like brooms and wiping water for cleaning tools like floor scrubbers. Figure 2As shown. When the angle between the cleaning head 1 and the handle 2 is any other, the handle 2 is offset to the side of the cleaning head 1 along the first direction; at this time, for cleaning tools such as floor scrubbers, it is easier to push water (pushing water is less strenuous), that is, as Figure 3 As shown.
[0081] In some embodiments, the limiting block 3 and the cleaning head 1 are detachably connected; and / or, the limiting block 3 and the hand handle 2 are detachably connected.
[0082] In the above embodiments, the limiting block 3 is detachably connected to the cleaning head 1 and the hand handle 2, which facilitates limiting the relative position of the cleaning head 1 and the hand handle 2 according to the user's needs.
[0083] Specifically, after the limiting block 3 and the cleaning head 1 are detachably connected, they form an integral structure with the cleaning head 1. At this time, the limiting block 3 and the hand handle 2 can still be detachably connected or form a limiting contact. Similarly, after the limiting block 3 and the hand handle 2 are detachably connected, they form an integral structure with the hand handle 2. At this time, the limiting block 3 and the cleaning head 1 can still be detachably connected or form a limiting contact.
[0084] Furthermore, this embodiment does not limit the specific connection method for the detachable connection between the limiting block 3, the cleaning head 1, and the handheld rod 2. The specific connection method for the detachable connection can be snap-fit, fastening, interference fit, etc.
[0085] In some embodiments, the limiting block 3 engages with the cleaning head 1 and / or the hand handle 2.
[0086] In the above embodiment, the limiting block 3 is snapped into the cleaning head 1 and the hand handle 2 to achieve a detachable connection, so that the limiting block 3 can be quickly assembled and disassembled, thereby quickly changing the usage posture of the cleaning tool according to the user's needs and improving the ease of use.
[0087] Specifically, when the limiting block 3 and the cleaning head 1 are engaged, a engaging member is provided on one of the limiting block 3 and the cleaning head 1, and a engaging engagement part that cooperates with the engaging member is provided on the other. Similarly, when the limiting block 3 and the hand handle 2 are engaged, a engaging member is provided on one of the limiting block 3 and the hand handle 2, and a engaging engagement part that cooperates with the engaging member is provided on the other.
[0088] In some embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8As shown, one of the limiting block 3 and the cleaning head 1 is provided with a locking interface 301, and the other is provided with a first buckle 101.

The locking interface 301 can be engaged with the second buckle 201 to make the limiting block 3 engage with the hand handle 2.
[0089] In the above embodiment, the limiting block 3 and the cleaning head 1 are engaged through the card interface 301 and the first buckle 101, and the limiting block 3 and the hand handle 2 are engaged through the card interface 301 and the second buckle 201, so that the limiting block 3 can be stably and quickly detached from the cleaning head 1 and the hand handle 2.
[0090] Specifically, in this embodiment, the limiting block 3 is provided with a card interface 301, and the cleaning head 1 is provided with a first buckle 101. The card interface 301 and the first buckle 101 are engaged to make the limiting block 3 and the cleaning head 1 engage. At the same time, the limiting block 3 is provided with a card interface 301, and the hand handle 2 is provided with a second buckle 201. The card interface 301 and the second buckle 201 are engaged to make the limiting block 3 and the hand handle 2 engage.
[0091] Furthermore, the card interface 301 is a recessed notch on the limiting block 3; the first buckle 101 is an elastic buckle on the cleaning head 1 that engages with the notch, and the second buckle 201 is another elastic buckle on the hand handle 2 that engages with the notch.
[0092] In some embodiments, such as Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, the limiting block 3 is slidably disposed between the cleaning head 1 and the hand handle 2; wherein, one of the limiting block 3 and the cleaning head 1 is provided with a protrusion 302, and the other is provided with a first groove 102. When the limiting block 3 and the cleaning head 1 are slidably engaged, the protrusion 302 is embedded in the first groove 102 and slides to guide the limiting block 3; and / or, one of the limiting block 3 and the hand handle 2 is provided with a protrusion 302, and the other is provided with a second groove 202. When the limiting block 3 and the hand handle 2 are slidably engaged, the protrusion 302 is embedded in the second groove 202 and slides to guide the limiting block 3.
[0093] In the above embodiment, the limiting block 3 and the cleaning head 1 are slidably engaged through the protrusion 302 and the first groove 102 to guide the installation of the limiting block 3 on the cleaning head 1; the limiting block 3 and the hand handle 2 are slidably engaged through the protrusion 302 and the second groove 202 to guide the installation of the limiting block 3 on the hand handle 2; thereby improving the assembly smoothness and assembly efficiency of the installation of the limiting block 3 with the cleaning head 1 and the hand handle 2.
[0094] Specifically, in this embodiment, the limiting block 3 is provided with a protrusion 302, and the cleaning head 1 is provided with a first groove 102. When the limiting block 3 and the cleaning head 1 are slidably engaged, the protrusion 302 is embedded in the first groove 102 and slides. At the same time, the limiting block 3 is provided with a protrusion 302, and the hand handle 2 is provided with a second groove 202. When the limiting block 3 and the hand handle 2 are slidably engaged, the protrusion 302 is embedded in the second groove 202 and slides.
[0095] Furthermore, in this embodiment, the limiting block 3 is provided with both a card interface 301 and a protrusion 302, and the card interface 301 and the protrusion 302 are integrated into a design, that is, a recessed notch is provided in a small section in the middle of the protrusion 302, thereby forming the card interface 301 in the protrusion 302.
[0096] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the cleaning head 1 is provided with a connecting part 103, and the hand handle 2 is provided with a first mounting plate 203 and a second mounting plate 204 located on both sides of the connecting part 103. The connecting part 103 is rotatably connected between the first mounting plate 203 and the second mounting plate 204. When the limiting block 3 is installed in the first installation position, the limiting block 3 is located between the connecting part 103 and the first mounting plate 203, so that the cleaning head 1 and the hand handle 2 are at a first angle. When the limiting block 3 is installed in the second installation position, the limiting block 3 is located between the connecting part 103 and the second mounting plate 204, so that the cleaning head 1 and the hand handle 2 are at a second angle.
[0097] In the above embodiment, a first assembly plate 203 and a second assembly plate 204 are provided on the handheld lever 2. After the cleaning head 1 and the handheld lever 2 rotate relative to each other, an installation space can be formed between the first assembly plate 203 or the second assembly plate 204 and the connection part 103 of the cleaning head 1, so as to install the limiting block 3 to limit the position of the cleaning head 1 and the handheld lever 2 after adjustment.
[0098] Specifically, the first mounting plate 203 and the second mounting plate 204 of the handheld lever 2 are arranged opposite to each other, thereby forming an installation gap between them. The connecting part 103 of the cleaning head 1 is located in the installation gap and is rotatably connected through the first rotating shaft. When the cleaning head 1 and the handheld lever 2 rotate relative to each other, multiple installation spaces can be formed between the first mounting plate 203 and the connecting part 103, and between the first mounting plate 203 and the connecting part 103. By installing the limiting block 3 in the corresponding installation space, the limiting block 3 can form a snap-fit or abutment between the first mounting plate 203 and the connecting part 103, thereby limiting the adjusted position of the cleaning head 1 and the handheld lever 2.
[0099] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the limiting block 3 has a first surface 303 and a second surface 304 facing away from each other, and the distance between the first surface 303 and the second surface 304 gradually decreases; the first assembly plate 203 has a clearance slope 205 on the side near the connecting part 103, and the outer edge of the clearance slope 205 is away from the connecting part 103; when the limiting block 3 is installed in the first installation position, the limiting block 3 is located between the connecting part 103 and the first assembly plate 203, and the first surface 303 is engaged with one of the connecting part 103 and the clearance slope 205, and the second surface 304 is engaged with the other surface 304. 04 abuts against the other of the connecting part 103 and the relief slope 205 to limit the relative position of the cleaning head 1 and the hand handle 2 to a first angle; when the limiting block 3 is installed in the second installation position, the limiting block 3 is located between the connecting part 103 and the second assembly plate 204, and the first surface 303 engages with one of the second assembly plate 204 and the connecting part 103, and the second surface 304 abuts against the other of the second assembly plate 204 and the connecting part 103 to limit the relative position of the cleaning head 1 and the hand handle 2 to a second angle.
[0100] In the above embodiment, a limiting block 3 with a first surface 303 and a second surface 304 with a gradually decreasing spacing is provided, as well as a first assembly plate 203 with a clearance slope 205, to ensure that an installation space of appropriate width is formed between the first assembly plate 203 or the second assembly plate 204 and the connecting part 103, thereby ensuring the installation stability of the limiting block 3.
[0101] Specifically, the distance between the first surface 303 and the second surface 304 of the limiting block 3 gradually decreases, so that the included angle between the first surface 303 and the second surface 304 is an acute angle. By changing the size of the acute angle, i.e., changing the relative distance between the first surface 303 and the second surface 304, the position of the first assembly plate 203 and the connecting part 103, and the first assembly plate 203 and the connecting part 103 after being engaged or abutted by the limiting block 3, can be changed, thereby changing the included angle between the cleaning head 1 and the hand handle 2. Specifically, the included angle between the first surface 303 and the second surface 304 is the angle at which the hand handle 2 can be offset to the side of the cleaning head 1; the larger the included angle between the first surface 303 and the second surface 304, the larger the angle at which the hand handle 2 can be offset to the side of the cleaning head 1; the smaller the included angle between the first surface 303 and the second surface 304, the smaller the angle at which the hand handle 2 can be offset to the side of the cleaning head 1. Meanwhile, the clearance slope 205 on the second assembly plate 204 can prevent the second assembly plate 204 from interfering with the connecting part 103 when the angle is adjusted. Of course, as the included angle between the first surface 303 and the second surface 304 increases or decreases, in order to avoid interference between the second assembly plate 204 and the connecting part 103, the tilt angle of the clearance slope 205 also increases or decreases accordingly, ensuring that the included angle between the first surface 303 and the second surface 304 is the same as the tilt angle of the clearance slope 205, so that an installation space equivalent to the width of the limiting block 3 is formed between the first assembly plate 203 or the second assembly plate 204 and the connecting part 103, thereby ensuring the installation stability of the limiting block 3, and thus ensuring the stability of the relative position of the cleaning head 1 and the hand handle 2 after the angle is adjusted.
[0102] Furthermore, the limiting block 3 can be configured as a structural component such as a triangular prism or a wedge; the yielding slope 205 can be configured as a frustum-shaped slope.
[0103] In some embodiments, such as Figure 8 As shown, in a preferred embodiment, the limiting block 3 is a wedge-shaped block, which has a vertical surface and an inclined surface facing away from each other. The first surface 303 is the vertical surface, and the second surface 304 is the inclined surface.
[0104] In the above embodiment, the limiting block 3, which is set as a wedge-shaped block, is designed to be embedded in the installation space formed between the first assembly plate 203 or the second assembly plate 204 and the connecting part 103, so as to limit the relative position of the cleaning head 1 and the hand handle 2 after the angle is adjusted.
[0105] Specifically, when the wedge-shaped limiting block 3 is installed in the first installation position, the cleaning head 1 and the hand handle 2 are at a first angle, that is, the cleaning head 1 and the hand handle 2 are collinear. At this time, the first surface 303 of the wedge-shaped block, that is, the vertical surface, engages or abuts with one side of the connecting part 103, and the second surface 304 of the wedge-shaped block, that is, the inclined surface, engages or abuts with the clearance inclined surface 205 on the second mounting plate 204. When the wedge-shaped limiting block 3 is installed in the second installation position, the cleaning head 1 and the hand handle 2 are at a second angle, that is, the hand handle 2 is offset to the side of the cleaning head 1. At this time, the first surface 303 of the wedge-shaped block, that is, the vertical surface, engages or abuts with the second mounting plate 204, and the second surface 304 of the wedge-shaped block, that is, the inclined surface, engages or abuts with the other side of the connecting part 103.
[0106] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, when the limiting block 3 is provided with a card interface 301 and a protrusion 302, the card interface 301 and the protrusion 302 are provided on the vertical surface; when the cleaning head 1 is provided with a first buckle 101 and a first groove 102, the first buckle 101 and the first groove 102 are provided on the connecting part 103; when the hand handle 2 is provided with a second buckle 201 and a second groove 202, the second buckle 201 and the second groove 202 are provided on the second assembly plate 204.
[0107] In the above embodiment, when the limiting block 3 is installed between the cleaning head 1 and the hand handle 2, it is guided by the sliding cooperation between the protrusion 302 and the first groove 102 and the second groove 202, and then it is locked and limited by the snap-fit interface 301 with the first snap-fit 101 and the second snap-fit 201, thereby ensuring the smoothness of assembly and the stability of installation.
[0108] Specifically, in this embodiment, the limiting block 3 is a wedge-shaped block, and the locking interface 301 and the protrusion 302 are simultaneously provided on the vertical surface of the limiting block 3, with the protrusion 302 protruding from the vertical surface. The locking interface 301 is a recessed notch on the protrusion 302. The connecting part 103 of the cleaning head 1 is simultaneously provided with a first buckle 101 and a first groove 102. The first groove 102 is a recessed strip-shaped groove, and the first buckle 101 is an elastic buckle provided in the strip-shaped groove. The second mounting plate 204 of the hand handle 2 is simultaneously provided with a second buckle 201 and a second groove 202. The second groove 202 is a recessed strip-shaped groove, and the second buckle 201 is an elastic buckle provided in the strip-shaped groove.
[0109] In some embodiments, such as Figure 2 , Figure 3 , Figure 9As shown, the first pivot is a spherical pivot 4, so that the hand handle 2 can swing relative to the cleaning head 1 in the first direction and in the second direction, with the first and second directions being perpendicular.
[0110] In the above embodiment, the first pivot is a spherical pivot 4, which allows the hand handle 2 to swing relative to the cleaning head 1 along the first and second directions, so that the user can adjust more usage angles of the cleaning tool as needed and improve the user experience.
[0111] Specifically, the spherical rotating shaft 4 is positioned along the first direction between the cleaning head 1 and the handheld lever 2.
[0112] In some embodiments, such as Figure 2 , Figure 3 , Figure 9 As shown, the spherical rotating shaft 4 includes a rod 401 and a ball 402 located in the middle of the rod 401. The rod 401 is fixedly connected to the handheld handle 2 and is arranged along the first direction. The ball 402 is connected to the spherical surface of the cleaning head 1.
[0113] In the above embodiment, the spherical rotating shaft 4 is fixedly connected to the handheld rod 2 via the rod body 401, and is connected to the spherical surface of the cleaning head 1 via the ball body 402, so that the handheld rod 2 can swing relative to the cleaning head 1 in both the first and second directions.
[0114] Specifically, the first assembly plate 203 and the second assembly plate 204 of the handheld rod 2 are provided with two shaft holes that conform to the shape of the rod body 401, and the connecting part 103 of the cleaning head 1 is provided with a spherical connecting hole that conforms to the shape of the ball 402; the spherical rotating shaft 4 passes through the first assembly plate 203, the connecting part 103 and the second assembly plate 204, and the two ends of the rod body 401 are fixedly connected to the corresponding shaft holes on the first assembly plate 203 and the second assembly plate 204, respectively, and the ball 402 is spherically connected to the spherical connecting hole on the connecting part 103.
[0115] Furthermore, the spherical connecting holes on the connecting part 103 of the cleaning head 1 of the spherical rotating shaft 4 are tightly fitted together, and the strong friction between the spherical body 402 and the spherical connecting holes is used to limit the position of the hand lever 2 after it swings relative to the cleaning head 1 in the second direction.
[0116] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the handheld lever 2 is rotatably connected to the connection part 103 of the cleaning head 1 via the first rotating shaft. The connection part 103 has blocking parts 104 on both sides. When the limiting block 3 and the handheld lever 2 are detachably connected and swing relative to the cleaning head 1 in the second direction with the handheld lever 2, the limiting block 3 abuts against the blocking part 104 to limit the limiting block 3 between the cleaning head 1 and the handheld lever 2.
[0117] In the above embodiment, blocking portions 104 are provided on both sides of the connecting portion 103 of the cleaning head 1 to provide a contact position for the limiting block 3 when the hand handle 2 swings relative to the cleaning head 1 in the second direction, so that the limiting block 3 is fixed between the cleaning head 1 and the hand handle 2 to maintain a stable position.
[0118] Specifically, when the hand lever 2 swings relative to the cleaning head 1 in the second direction, the limiting block 3 swings together with the hand lever 2 in the second direction relative to the cleaning head 1. At this time, the blocking part 104 provided on both sides of the connecting part 103 serves as an extension structure of the connecting part 103, so that the limiting block 3 can continuously maintain contact with the cleaning head 1.
[0119] Furthermore, the blocking part 104 is constructed as an arc-shaped structural member, the diameter of which is equivalent to the distance from the limiting block 3 to the ball 402 of the spherical rotating shaft 4; the curvature of one side of the blocking part 104 does not exceed 90°.
[0120] In some embodiments, such as Figure 10 , Figure 11 As shown, the first rotating shaft is a straight rotating shaft 5 and is arranged along the second direction so that the hand handle 2 can swing relative to the cleaning head 1 along the first direction; the first direction and the second direction are perpendicular.
[0121] In the above embodiment, the first rotating shaft is a straight rotating shaft 5, which allows the hand handle 2 to swing relative to the cleaning head 1 in the first direction, so that the user can adjust the cleaning tool to more usage angles as needed.
[0122] Specifically, two connecting plates are connected between the first assembly plate 203 and the second assembly plate 204 of the handheld lever 2. The two connecting plates are provided with two shaft holes that conform to the shape of the straight rotating shaft 5. The connecting part 103 of the cleaning head 1 is provided with one shaft hole that conforms to the shape of the straight rotating shaft 5. The straight rotating shaft 5 passes through the two connecting plates and the connecting part 103. The two ends of the straight rotating shaft 5 are rotatably connected to the corresponding shaft holes on the two connecting plates, and the middle part of the straight rotating shaft 5 is rotatably connected to the shaft hole on the connecting part 103.
[0123] In some embodiments, such as Figure 12 , Figure 13As shown, the handheld lever 2 includes a first segment 206 rotatably connected to the cleaning head 1, and a second segment 207 for holding. The second segment 207 is rotatably connected to the first segment 206 via a second pivot 208 arranged in a first direction, so that the second segment 207 can swing relative to the first segment 206 in a second direction, and thus swing relative to the cleaning head 1 in a second direction.
[0124] In the above embodiment, while the first rotating shaft is set as a straight rotating shaft 5 arranged along the second direction, the hand handle 2 is set as a rod that allows the second segment 207 to swing relative to the first segment 206 in the second direction using the second rotating shaft 208 arranged along the first direction. This allows the hand handle 2 or the second segment 207 on the hand handle 2 to swing relative to the cleaning head 1 in the first and second directions respectively, so that the user can adjust more usage angles as needed and improve the user experience.
[0125] Specifically, when the cleaning head 1 and the handheld handle 2 are at a first angle, the second rotating shaft 208 is a straight rotating shaft arranged along the first direction.
[0126] This embodiment describes a cleaning tool with the following usage states and adjustment methods:
[0127] When the limiting block 3 is installed in the first installation position, the cleaning head 1 and the hand handle 2 are at the first angle, that is, the cleaning head 1 and the hand handle 2 are collinear. At this time, the first surface 303 of the limiting block 3 and one side of the connecting part 103 are engaged through the card interface 301 and the first buckle 101. The second surface 304 of the limiting block 3 abuts against the relief slope 205 on the first assembly plate 203, and the other side of the connecting part 103 abuts against the second assembly plate 204.
[0128] When the limiting block 3 is installed in the second installation position, the cleaning head 1 and the hand handle 2 are at a second angle, that is, the hand handle 2 is offset to the side of the cleaning head 1; at this time, the first surface 303 of the limiting block 3 is engaged with the second assembly plate 204 through the card interface 301 and the second buckle 201, the second surface 304 of the limiting block 3 abuts against one side of the connecting part 103, and the other side of the connecting part 103 abuts against the clearance slope 205 on the first assembly plate 203.
[0129] When the angle between the cleaning head 1 and the handle 2 is adjusted from the first angle to the second angle, remove the limiting block 3 that is engaged with one side of the connecting part 103 via the locking interface 301 and the first buckle 101. Rotate the handle 2 relative to the cleaning head 1 in the first direction so that one side of the connecting part 103 abuts against the relief slope 205 on the first mounting plate 203. Insert the limiting block 3 between the other side of the connecting part 103 and the second mounting plate 204, and engage the first side 303 of the limiting block 3 with the second mounting plate 204 via the locking interface 301 and the second buckle 201. The second side 304 of the limiting block 3 abuts against the connecting part 103. When the angle between the cleaning head 1 and the handle 2 is adjusted from the second angle to the first angle, the adjustment process is reversed.
[0130] 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.
