Description

Technical Field

[0001] This utility model relates to the field of cleaning tools technology, and in particular to a squeezing component and a mop. Background Technology

[0002] In related technologies, in order to clean flat mops, a wringer is usually slidably installed on the mop handle. The wringer has a squeezing port and a scraper. Users can insert the mop board into the squeezing port and move the wringer up and down to clean the wiping material on the mop board through the scraper.

[0003] However, existing wringer frames are usually divided into two parts for ease of manufacturing, with the two ends of the scraper fixed to one of the supports. But when the mop blade moves in the squeezing nozzle, it applies a relatively large force to the scraper, which can easily cause the scraper to move in the nozzle and detach from it. Utility Model Content

[0004] This invention provides a squeezing component and a mop to solve the technical problem in related technologies where the scraping component easily detaches from the wringer.

[0005] In a first aspect, this utility model provides a pressing assembly having a pressing port for inserting a mop board, comprising:

[0006] A first bracket is provided with a stopper for abutting against the top surface of the mop board, and a plug plate is provided on the first bracket extending away from the stopper.

[0007] A scraping component, which is used to scrape and / or squeeze the wiping material of the mop board, and the scraping component is provided with a limiting groove extending in a first direction along which the mop board is inserted into the squeezing port;

[0008] The second bracket is connected to the first bracket to clamp the scraper, and when the second bracket is connected to the first bracket, the plug plate extends into the limiting groove. The second bracket and the first bracket restrict the scraper from moving towards or away from the first bracket in a second direction. The two opposite sidewalls of the limiting groove restrict the scraper from moving along a third direction that is perpendicular to both the second direction and the first direction.

[0009] The scraper in this application has a limiting groove, and a connecting plate is provided on the first bracket. The insertion and engagement of the connecting plate with the limiting groove restricts the movement of the scraper in a third direction. At the same time, the second bracket and the first bracket clamp the scraper, restricting its movement in a second direction, either towards or away from the first bracket. In this way, through the cooperation of the second bracket, the first bracket, the connecting plate, and the limiting groove, the displacement of the scraper in at least two directions is restricted, greatly limiting the freedom of movement of the scraper in the extrusion port. This avoids the problem of the scraper easily detaching from the extrusion port when the force applied by the mop board is large, resulting in a better user experience.

[0010] In one feasible implementation, the end of the plug plate is provided with a limiting part, and the bottom of the limiting groove is provided with a mating part. When the plug plate extends into the limiting groove, the limiting part and the mating part cooperate to restrict the movement of the scraping member along the first direction.

[0011] The bottom of the limiting groove and the end of the plug-in plate in this application are respectively provided with a limiting part and a mating part. After the plug-in plate is inserted into the limiting groove, the movement of the scraping component along the first direction of the mop board insertion extrusion port can be restricted through the cooperation of the limiting part and the mating part. In this way, through the cooperation of the second bracket, the plug-in plate and the limiting groove, the displacement of the scraping component in three directions is restricted, further avoiding the problem that the scraping component is easy to detach from the extrusion port when the force applied by the mop board is large, resulting in a better user experience.

[0012] In one feasible implementation, one of the limiting portion and the mating portion is a protrusion and the other is a groove. When the plug plate extends into the limiting groove, the protrusion and the groove cooperate to restrict the movement of the scraping member along the first direction.

[0013] In one feasible implementation, the limiting part is a plurality of grooves, the shapes of which are not exactly the same; the mating part is a plurality of protrusions, the shapes of which are adapted to the shapes of the plurality of grooves; when the plug plate extends into the limiting groove, the plurality of protrusions correspond one-to-one with the plurality of grooves and cooperate to restrict the movement of the scraping member along the first direction.

[0014] In one feasible implementation, the second bracket is provided with the plug-in plate at both ends, and the scraping member is provided with the limiting groove on the side of both ends near the first bracket; when the second bracket is connected to the first bracket, the plug-in plates at both ends of the second bracket extend into the limiting grooves at both ends of the scraping member.

[0015] In one feasible implementation, the second bracket is provided with two opposing mounting positions; both ends of the scraping member respectively mate with the mounting positions and are pre-installed on the second bracket so as to facilitate the connection between the second bracket and the first bracket.

[0016] In one feasible implementation, the two ends of the second bracket are provided with fixing plates extending toward the first bracket, and the fixing plates are provided with slots at both ends along the first direction; when the first bracket and the second bracket approach each other, the plug-in plate is inserted into the slots along both sides of the first direction and slides along the slots until the first bracket and the second bracket are engaged and fixed.

[0017] In one feasible implementation, mounting plates are provided at both ends of the first bracket in a direction close to the second bracket. A clearance groove is provided between the mounting plate and the plug-in plate. A locking plate is provided at the end of the fixing plate away from the second bracket. A spring arm is provided on the side of the plug-in plate close to the clearance groove. A locking block is provided at the end of the spring arm. A locking groove is provided on the inner side of the fixing plate. When the first bracket and the second bracket approach each other, the plug-in plate is inserted into the slot along both sides in the first direction and slides along the slot until the locking plate extends into the clearance groove and the locking block engages with the locking groove, so that the first bracket and the second bracket are engaged and fixed.

[0018] In one feasible implementation, the card plate extends toward the first bracket, and the bottom of the clearance groove has a through hole; the card plate extends into the clearance groove and through the through hole into the area enclosed by the bottom of the clearance groove, the mounting plate, and the plug plate.

[0019] Secondly, this utility model provides a mop, including a mop handle, a mop plate hinged to one end of the mop handle, and a wringing mechanism slidably disposed on the mop handle, wherein the wringing mechanism includes the squeezing component described in any of the above embodiments.

[0039] 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.

[0040] The extrusion assembly and mop of this utility model are described below with reference to the accompanying drawings.

[0041] Figure 1 and Figure 2 This is one of the structural schematic diagrams of the extrusion assembly provided by this utility model, such as... Figure 1 and Figure 2 As shown, this utility model provides a squeezing assembly 10, which has a squeezing port 10A for inserting a mop board 20, and includes a first bracket 11, a scraping component 12, and a second bracket 13.

[0042] The first bracket 11 is provided with abutment member 111 for abutting against the top surface of the mop board 20, and a plug-in plate 112 extends from the first bracket 11 away from the abutment member 111. Optionally, the abutment member 111 can be a guide wheel or guide rib for guiding the mop board and providing support to the top surface of the mop board 20; or, the abutment member 111 can also be a driving member that moves under the drive of the mop board 20 to drive other components, such as a gear or rack, which can be a water spraying mechanism for spraying water onto the wiping object or a water transfer mechanism for moving water squeezed out from the wiping object to other areas.

[0043] The scraping member 12 is used to scrape and / or squeeze the wiping material on the mop board 20, and the scraping member 12 is provided with a limiting groove 121 extending in a first direction X along the insertion squeezing port 10A of the mop board 20. The limiting groove 121 can be provided on the side of the scraping member 12 near the abutment member 111. In order to avoid interference with the mop board inserted into the squeezing port 10A, the limiting groove 121 can be provided as close as possible to the end of the scraping member 12.

[0044] The second bracket 13 is connected to the first bracket 11 to clamp the scraper 12. When the second bracket 13 is connected to the first bracket 11, the plug plate 112 extends into the limiting groove 121. The second bracket 13 and the first bracket 11 restrict the scraper 12 from moving towards or away from the first bracket 11 in the second direction Y. The two opposite side walls of the limiting groove 121 restrict the scraper 12 from moving in the third direction Z, which is perpendicular to both the second direction Y and the first direction X.

[0045] For example, the second direction Y is the arrangement direction of the first support 11 and the second support 13, or it can be the thickness direction of the mop board 20 inserted into the squeezing port 10A. The third direction Z is the length direction of the scraping member 12. For example, if the scraping member 12 is a squeezing roller, then the third direction Z is the axial direction of the squeezing roller.

[0046] Optionally, the scraping component 12 can be a squeezing roller. In this case, the insertion plate 112 inserted into the limiting groove 121 not only limits the axial movement of the squeezing roller but also limits its circumferential movement. Alternatively, the scraping component 12 can be a comb, a scraper, or other components with scraping and / or squeezing effects. Specifically, the scraping component 12 can be a plate-shaped component with one or more protruding ridges on the side near the squeezing port 10A. These ridges scrape and / or squeeze the wiping material of the mop blade inserted into the squeezing port. A drainage hole can also be provided between two adjacent ridges to facilitate the discharge of wastewater squeezed out by the ridges from the squeezing port.

[0047] Optionally, the second bracket 13 and the first bracket 11 can be fixedly connected or detachably connected. In actual installation, the scraper 12 can be pre-installed on the second bracket 13, and then the two brackets are brought closer to each other until the first bracket 11 and the second bracket 13 clamp the scraper 12 and the plug plate 112 extends into the limiting groove 121. The plug-in cooperation between the plug plate 112 and the limiting groove 121 can restrict the movement of the scraper 12 in the third direction Z. At the same time, the clamping of the scraper 12 by the second bracket 13 and the first bracket 11 can restrict the movement of the scraper 12 in the second direction Y, which is closer to or farther away from the first bracket 11. In this way, through the cooperation of the second bracket 13, the first bracket 11, the plug plate 112 and the limiting groove 121, the displacement of the scraper 12 in at least two directions is restricted, which greatly limits the degree of freedom of the scraper 12 in the squeezing port 10A. This avoids the problem that the scraper 12 is easy to detach from the squeezing port 10A when the force applied by the mop board 20 is large, resulting in a better user experience.

[0048] Optionally, the first bracket 11 is further provided with an abutment portion. The two brackets approach each other until the abutment portion clamps the scraper 12 with the second bracket 13 and the insertion plate 112 extends into the limiting groove 121. The abutment portion and the second bracket 13 can limit the scraper 12 to move in the second direction Y, either closer to or away from the first bracket 11. Alternatively, the two brackets approach each other until the insertion plate 112 extends into the limiting groove 121 and abuts against the bottom of the limiting groove 121. At this time, the end of the insertion plate 112 clamps the scraper 12 with the second bracket 13. That is, the end of the insertion plate 112 and the second bracket 13 can limit the scraper 12 to move in the second direction Y, either closer to or away from the first bracket 11.

[0049] In one feasible implementation, a limiting portion is provided at the end of the plug-in plate 112, and a mating portion is provided at the bottom of the limiting groove 121. When the plug-in plate 112 extends into the limiting groove 121, the limiting portion and the mating portion cooperate to restrict the movement of the scraping member 12 along the first direction X. In this way, through the cooperation of the second bracket 13, the first bracket 11, the plug-in plate 112, and the limiting groove 121, the scraping member 12 is limited in the first direction X when the mop plate 20 is inserted into the squeezing port 10A, in the second direction Y which is close to or away from the first bracket 11, and in the third direction Z which is perpendicular to the first direction X and the second direction Y respectively. That is, the position of the scraping member 12 in the squeezing port 10A is fixed, which maximizes the restriction of the degree of freedom of movement of the scraping member 12 in the squeezing port 10A, and further avoids the problem that the scraping member 12 is easy to detach from the squeezing port 10A when the force applied by the mop plate 20 is large, resulting in a better user experience.

[0050] In one feasible implementation, one of the limiting part and the mating part is a protrusion 1211 and the other is a groove 1121. When the plug plate 112 extends into the limiting groove 121, the protrusion 1211 and the groove 1121 cooperate to restrict the movement of the scraping member 12 along the first direction X.

[0051] Optional, such as Figure 3 As shown, a groove 1121 is provided at the end of the plug-in plate 112 to form a limiting part, and a protrusion 1211 is provided at the bottom of the limiting groove 121 to form a mating part. When the second bracket 13 and the first bracket 11 approach each other to connect, the plug-in plate 112 extends into the limiting groove 121, so that the protrusion 1211 at the bottom of the limiting groove 121 enters the groove 1121 at the end of the plug-in plate 112. The sidewall of the groove 1121 can limit the protrusion 1211 on both sides along the first direction X, so as to restrict the movement of the scraping member 12 along the first direction X.

[0052] In one feasible implementation, such as Figure 3 As shown, the limiting part can be multiple grooves 1121, and the shapes of the multiple grooves 1121 are not exactly the same; for example Figure 4 As shown, the mating part can be a plurality of protrusions 1211, the shape of the plurality of protrusions 1211 being adapted to the shape of the plurality of grooves 1121; when the plug plate 112 extends into the limiting groove 121, the plurality of protrusions 1211 and the plurality of grooves 1121 correspond one-to-one and cooperate to restrict the scraping member 12 from moving along the first direction X.

[0053] Optionally, the end of the plug-in plate 112 is formed with multiple grooves 1121 of not exactly the same shape, that is, among the multiple grooves 1121, at least one groove 1121 has a different shape than the other grooves 1121. The bottom of the limiting groove 121 is formed with multiple protrusions 1211, and the protrusions 1211 correspond one-to-one with the grooves 1121 and are adapted in shape. If the multiple grooves 1121 have the same shape, then their engagement method after engaging with the protrusions 1211 is the same. That is, when the scraping member 12 moves under force, the force fed back from each groove 1121 to the protrusion 1211 is the same. If a large force is encountered, causing one of the protrusions 1211 to disengage from its corresponding groove 1121, the other protrusions 1211 will also disengage from their corresponding grooves 1121. When multiple grooves 1121 contain other grooves 1121 of different shapes, if a large force is applied, the scraping member 12 may move along the direction of the force, potentially causing one of the protrusions 1211 to detach from its corresponding groove 1121. In this case, the grooves 1121 of different shapes can limit the protrusion 1211 located within them in the direction of the force, thereby restricting the movement of the scraping member 12 along the direction of the force and preventing the protrusion 1211 from detaching from its corresponding groove 1121. That is, different grooves 1121 limit different protrusions 1211 in different directions, and multiple grooves 1121 cross-limit multiple protrusions 1211, which can minimize the movement of the scraping member 12 under force.

[0054] In one feasible implementation, such as Figure 3 As shown, both ends of the second bracket 13 are equipped with plug-in plates 112. Figure 4 As shown, limiting grooves 121 are provided at both ends of the scraper 12 near the first bracket 11. When the second bracket 13 is connected to the first bracket 11, the plug plates 112 at both ends of the second bracket 13 extend into the limiting grooves 121 at both ends of the scraper 12. Compared with single-end limiting or only one limiting, both ends of the scraper 12 are limited, which improves the stability of the scraper 12 in the extrusion port 10A.

[0055] In one feasible implementation, such as Figure 5 As shown, the second bracket 13 is provided with two opposite mounting positions 131; the two ends of the scraping member 12 respectively cooperate with the mounting positions 131 and are pre-installed on the second bracket 13 so that the second bracket 13 can be connected to the first bracket 11.

[0056] For example, assuming the scraping component 12 is a plate-shaped component, one end of which is provided with a limiting groove 121 or both ends are provided with limiting grooves 121. The end of the plate-shaped component protrudes from the side wall of the limiting groove 121 away from the extrusion port 10A and abuts against the mounting area 131. For example, assuming the mounting position 131 is a mounting groove, the end of the plate-shaped component can be a columnar block protruding from the side wall of the limiting groove 121 away from the extrusion port 10A. During pre-installation, the columnar block at the end of the plate-shaped component is engaged in the mounting groove, so that the plate-shaped component can be installed on the second bracket 13, which facilitates the subsequent clamping of the plate-shaped component by the second bracket 13 and the first bracket 11.

[0057] In one feasible implementation, such as Figure 5 As shown, the two ends of the second bracket 13 extend towards the first bracket 11 and are provided with fixing plates 132. The fixing plates 132 are provided with slots 1323 at both ends along the first direction X. When the first bracket 11 and the second bracket 13 approach each other, the plug-in plate 112 is inserted into the slots 1323 along both sides of the first direction X and slides along the slots 1323 until the first bracket 11 and the second bracket 13 are engaged and fixed.

[0058] For example, the first bracket 11 and the second bracket 13 can be engaged. However, since the force exerted on both the first bracket 11 and the second bracket 13 when the mop plate 20 is inserted into the squeezing port 10A is relatively large, if the engagement position of the first bracket 11 and the second bracket 13 is offset, resulting in an unstable engagement relationship, it is possible that the first bracket 11 and the second bracket 13 may disengage when the mop plate 20 is inserted into the squeezing port 10A. To stabilize the engagement relationship between the first bracket 11 and the second bracket 13, slots 1323 can be provided at both ends of the fixing plates 13 at both ends of the second bracket 13 along the first direction X. These slots 1323 can extend along the second direction Y. When the first bracket 11 and the second bracket 13 approach each other along the second direction Y, the insertion plate 112 can be inserted into the slots 1323 along both sides of the first direction X and slide along the slots 1323 until the first bracket 11 and the second bracket 13 are engaged and fixed.

[0059] In one feasible implementation, such as Figure 6 As shown, mounting plates 113 extend from both ends of the first bracket 11 towards the second bracket 13, and a clearance groove 114 is provided between the mounting plate 113 and the plug-in plate 112. Figure 5As shown, the fixed plate 132 has a retaining plate 1321 at the end away from the second bracket 13. A spring arm 1122 is provided on the side of the plug-in plate 112 near the clearance groove 114, and a retaining block 1123 is provided at the end of the spring arm 1122. A retaining groove 1322 is provided on the inner side of the fixed plate 132. When the first bracket 11 and the second bracket 13 approach each other, the plug-in plate 112 is inserted into the slot 1323 along both edges in the first direction X and slides along the slot 1323 until the retaining plate 1321 extends into the clearance groove 114 and the retaining block 1123 engages with the retaining groove 1322, thereby locking and fixing the first bracket 11 and the second bracket 13.

[0060] For example, when the first bracket 11 and the second bracket 13 approach each other, the inner side of the fixing plate 132 first contacts the locking block 1123. At this time, the plug-in plate 112 inserts into the slot 1323 along the two sides of the first direction X, so that the inner side of the fixing plate 132 squeezes the locking block 1123. At this time, the spring arm 1122 deforms and drives the locking block 1123 to move away from the inner side of the fixing plate 132 to avoid it, until the locking block 1123 moves to the slot 1322 on the inner side of the fixing plate 132. At this time, the slot 1322 restricts the locking block 1123 from disengaging in the opposite direction to the installation direction, thereby restricting the first bracket 11 and the second bracket 13 from disengaging from each other.

[0061] In one feasible implementation, such as Figure 6 and Figure 7 As shown, the card plate 1321 extends toward the first bracket 11, and the bottom of the clearance groove 114 has a through hole 1141; the card plate 1321 extends into the clearance groove 114 and through the through hole 1141 into the area B enclosed by the bottom of the clearance groove 114 and the first bracket 11.

[0062] For example, based on the engagement of the locking block 1123 and the locking slot 1322, the locking plate 1321 extends to the bottom of the clearance slot 114. That is, the mounting plate 113 and the fixing plate 132 are limited in both positive and negative directions along the third direction Z. After the first bracket 11 and the second bracket 13 are engaged and fixed, they are difficult to separate even if they are subjected to external pressure or drag, which greatly improves the stability of the connection between the first bracket 11 and the second bracket 13.

[0063] This utility model also provides a mop, such as Figure 8 As shown, the mop includes a mop handle 40, a mop plate 20 hinged to one end of the mop handle, and a wringing mechanism 30 slidably disposed on the mop handle. The wringing mechanism 30 includes the squeezing component 10 described in any of the above embodiments.

[0064] For example, the squeezing mechanism 30 has a connector 301 and a gripping portion 302. Specifically, the connector 301 can be provided on the first support 11 of the squeezing assembly 10, and the gripping portion 302 is provided at the end of the connector 301 away from the first support 11. The connector 301 can be an arc-shaped plate that partially surrounds the mop handle 40, or it can be multiple connecting rods arranged circumferentially along the mop handle 40.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
