[0114] The squeezing device and mop bucket of the present application will be described below in combination with the drawings.

[0115] According to an aspect, Figure 1 is one of the structural schematic diagrams of the squeezing device provided by the present application, like Figure 1As shown, the squeezing device is arranged in the mop bucket for squeezing the mop head, the squeezing device comprises a squeezing module 101 and a supporting module 102, the supporting module 102 is used for placing the mop head and moving under the drive of the mop head;

[0116] The squeezing module 101 comprises a pressing member 1011, a swinging member 1012 and a rotating member 1013, the rotating member 1013 is rotatably connected with the supporting module 102, and the bottom end A of the rotating member 1013 slides along the bottom of the mop bucket; the pressing member 1011 is movably connected with the supporting module 102, and the two ends of the swinging member 1012 are movably connected with the pressing member 1011 and the rotating member 1013 respectively;

[0117] When the mop head is placed in the supporting module 102, the force applying part B of the pressing member 1011 is located at the top of the mop head; when the supporting module 102 is driven to move towards the bottom of the mop bucket, the bottom end A of the rotating member 1013 slides along the bottom of the mop bucket to drive the rotating member 1013 to rotate relative to the supporting module 102, the rotation of the rotating member 1013 drives the swinging member 1012 to swing, and the swinging of the swinging member 1012 drives the pressing member 1011 to move towards the bottom of the mop bucket relative to the supporting module 102;

[0118] The movement of the pressing member 1011 causes the force applying part B to apply force to the top of the mop head, so as to squeeze the mop of the mop head located between the force applying part B and the supporting module 102.

[0119] In some embodiments, as shown, Figure 1 As shown, when the user does not drive the supporting module 102 to move towards the bottom of the mop bucket by pressing the mop head, the bottom end A of the rotating member 1013 can be perpendicular to the bottom of the mop bucket; during the process that the user drives the supporting module 102 to move towards the bottom of the mop bucket by pressing the mop head, the bottom end A of the rotating member 1013 continuously slides along the bottom of the mop bucket towards the side wall of the mop bucket, so that the rotating member 1013 rotates at a certain angle relative to the supporting module 102 which only moves towards the bottom of the mop bucket, and then the swinging member 1012 can be driven to swing, so that the end of the swinging member 1012 close to the pressing member 1011 drives the pressing member 1011 to move towards the bottom of the mop bucket to squeeze the mop head.

[0120] The utility model provides an extrusion device, the extrusion device is arranged in the mop bucket, is used for extruding mop head, specific extrusion device includes extrusion module 101 and support module 102, and the user can place the mop head of mop on support module 102, and the support module 102 is driven to move to the direction of the bottom of the bucket of the mop bucket by pressing the mop head downwards, at this moment, the bottom end A of the rotating part 1013 in the extrusion module 101 is slid along the bottom of the bucket of the mop, so that the rotating part 1013 rotates compared with support module 102, and then the rotation of the rotating part 1013 drives the swing part 1012 in the extrusion module 101 to swing, finally drives the pressing part 1011 in the extrusion module 101 to move to the direction of the bottom of the bucket compared with support module 102, in the process, the force applying part B of the pressing part 1011 can be close to the top of the mop head constantly, until the support of support module 102 is used to apply force to the top of the mop head, so as to extrude the mop head, which is convenient for effectively extruding the mop head of rubber cotton head type, and the user operation is simple.

[0121] In some embodiments, Figure 2 It is the structure schematic diagram two of the extrusion device provided by the utility model, as Figure 2 The swing part 1012 is rotatably connected with the rotating part 1013, and the first rotation axis C between the swing part 1012 and the rotating part 1013 and the second rotation axis D between the rotating part 1013 and the support module 102 are arranged in a staggered manner.

[0122] The bottom end A of the rotating part 1013 slides along the bottom of the bucket of the mop, drives the rotating part 1013 to rotate around the second rotation axis D relative to the support module 102, and at the same time rotates around the first rotation axis C relative to the swing part 1012, and then drives the swing part 1012 to swing.

[0123] In the embodiment of the application, the first rotation axis C between the swing part 1012 and the rotating part 1013 and the second rotation axis D between the rotating part 1013 and the support module 102 are arranged in a staggered manner to form a lever, the resistance arm is formed between the first rotation axis C and the second rotation axis D, and the power arm is formed between the second rotation axis D and the bottom end A of the rotating part 1013, the longer the resistance arm is, the more labor-saving it is, but the displacement during extrusion is also longer; the first rotation axis C can be arranged at any position, if the first rotation axis C and the second rotation axis D are arranged coaxially, it is the most labor-consuming, but the displacement is the shortest; if the first rotation axis C and the second rotation axis D are arranged in a staggered manner, the distance between the first rotation axis C and the second rotation axis D can be set according to the size of the mop bucket to be used and the size of the rubber cotton head to be extruded, so that labor-saving and extrusion displacement can be considered.

[0124] In some embodiments, as Figure 2As shown, the first rotation axis C can be arranged between the second rotation axis D and the bottom end A of the rotating member 1013.

[0125] In the embodiment, the first rotation axis C is arranged between the second rotation axis D and the bottom end A of the rotating member 1013, so that the bottom end A of the rotating member 1013 rotates relative to the swing member 1012 around the first rotation axis C while sliding along the bottom of the mop barrel to drive the rotating member 1013 to rotate relative to the support module 102 around the second rotation axis D, thereby driving the swing member 1012 to swing, and ensuring normal operation of the squeezing device.

[0126] In some embodiments, Figure 3 is a structural schematic view of the rotating member in the squeezing device provided by the utility model, as Figures 1 to 3 As shown, the side wall of the rotating member 1013 is recessed to form a first mounting groove 10131, and the end of the swing member 1012 is provided with a first rotation shaft column 10121.

[0127] The end of the swing member 1012 extends into the first mounting groove 10131, and the first rotation shaft column 10121 is rotationally connected with the side wall of the first mounting groove 10131.

[0128] In the embodiment, the first rotation shaft column 10121 at the end of the swing member 1012 extends into the first mounting groove 10131 formed by the recess of the side wall of the rotating member 1013, and is rotationally connected with the side wall of the first mounting groove 10131, thereby realizing the rotational connection between the rotating member 1013 and the swing member 1012, and the connection mode is simple and reliable.

[0129] In some embodiments, a specific implementation of the first mounting groove 10131 is provided. As Figures 1 to 3 As shown, the first mounting groove 10131 penetrates through the rotating member 1013 and has opposite first and second openings, and the side wall of the first mounting groove 10131 is recessed to form a first plug-in groove at one end close to the second opening.

[0130] The end of the swing member 1012 extends into the first mounting groove 10131 from the first opening until the first rotation shaft column 10121 extends out of the second opening and enters the first plug-in groove, and is rotationally connected with the side wall of the first mounting groove 10131 through the first plug-in groove.

[0131] In the embodiment of the present application, the first installation slot 10131 penetrates the rotating part 1013 and has opposite first and second openings. The first rotating shaft column 10121 at the end of the swing part 1012 can extend into the first installation slot 10131 from the first opening and then extend out of the second opening and into the first plug-in slot for installation. The first opening facilitates the smooth installation of the first rotating shaft column 10121 into the first plug-in slot. The second opening ensures that the rotating part 1013 and the swing part 1012 are not easily separated when the rotating part 1013 rotates to drive the swing part 1012 to swing, thereby ensuring that the extrusion device can work stably.

[0132] In some embodiments, a specific implementation of the first plug-in slot is provided. As shown in Figure 3 the first plug-in slot has a translation section and an inclined section that are in communication with each other. The translation section extends in a direction from the second opening to the first opening. The inclined section extends in a direction close to the second rotating shaft D. After the first rotating shaft column 10121 extends out of the second opening, it enters the translation section of the first plug-in slot and slides along the translation section to the inclined section until it is rotationally connected to one end of the inclined section close to the second rotating shaft D.

[0133] In the embodiment of the present application, the first plug-in slot has a translation section and an inclined section that are in communication with each other. After the first rotating shaft column 10121 extends out of the second opening, it enters the translation section of the first plug-in slot and can slide along the translation section to the inclined section until it is rotationally connected to one end of the inclined section close to the second rotating shaft D. This arrangement allows the first rotating shaft column 10121 of the swing part 1012 to be clamped in the inclined section when the rotating part 1013 rotates, and it is not easy to come out of the second opening through the translation section. The connection is reliable, which ensures that the extrusion device can work stably.

[0134] In some embodiments, a specific implementation of the movable connection between the swing part and the pressing part is provided. As shown in Figure 1 and 2 the swing part 1012 is rotationally connected to the pressing part 1011.

[0135] When the swing part 1012 swings, it rotates relative to the pressing part 1011, and at the same time drives the pressing part 1011 to move relative to the support module 102 in a direction close to the bottom of the barrel.

[0136] In the embodiment of the present application, when the rotating part 1013 rotates to drive the swing part 1012 to swing, the swing part 1012 rotates relative to the pressing part 1011, and at the same time drives the pressing part 1011 to move relative to the support module 102 in a direction close to the bottom of the barrel, so as to extrude the wiping material of the mop head. The connection structure is simple and reliable, and the extrusion function of the extrusion module can be realized.

[0137] In some embodiments, a specific implementation of mounting the swing member 1012 to the pressing member 1011 is provided. As shown in Figures 1 to 3 the side wall of the pressing member 1011 is recessed to form a second mounting groove 10111, and the end of the swing member 1012 is provided with a second rotating shaft column 10122;

[0138] The end of the swing member 1012 extends into the second mounting groove 10111, and the second rotating shaft column 10122 is rotationally connected to the side wall of the second mounting groove 10111.

[0139] In the embodiments of the present application, the second rotating shaft column 10122 provided at the end of the swing member 1012 can extend into the second mounting groove 10111 recessed in the side wall of the pressing member 1011 for mounting, and the connection structure is simple and reliable.

[0140] In some embodiments, a specific implementation of the second mounting groove 10111 is provided. As shown in Figures 1 to 3 the second mounting groove 10111 has a third opening, and the side wall of the second mounting groove 10111 is recessed to form a second insertion groove near one end of the third opening;

[0141] The end of the swing member 102 extends into the second mounting groove 10111 from the third opening, so that the second rotating shaft column 10122 extends into the second insertion groove and is rotationally connected to the second insertion groove.

[0142] In the embodiments of the present application, the third opening is provided to facilitate the extension of the second rotating shaft column 10122 into the second insertion groove and the rotational connection therewith, and the second insertion groove facilitates the reliable connection with the second rotating shaft column 10122.

[0143] In some embodiments, as shown in Figure 1 and 2 the swing member 1012 is in the shape of a circular arc. For example, a curved connecting rod is used.

[0144] In the embodiments of the present application, the swing member 1012 is provided in the shape of a circular arc, which is not easy to collide with other parts of the extrusion device and be damaged, thereby improving the reliability of the extrusion device to a certain extent and prolonging the service life of the extrusion device.

[0145] In some embodiments, as shown in Figure 1 and 2 the curvature of the circular arc-shaped swing member 1012 near one end of the pressing member 1011 is different from the curvature near one end of the rotating member 1013.

[0146] In the embodiment of the present application, the curvature of the arc-shaped swing member 1012 close to one end of the pressing member 1011 is different from the curvature close to one end of the rotating member 1013, so that the pressing member 1011 and the rotating member 1013 are not easy to collide when the swing member 1012 swings, thereby ensuring that the extrusion device can work normally.

[0147] In some embodiments, as shown in Figure 1 and 2 , the curvature of the arc-shaped swing member 1012 close to one end of the pressing member 1011 is greater than the curvature close to one end of the rotating member 1013.

[0148] In the embodiment of the present application, high-strength extrusion can be achieved by short displacement, which facilitates the rotation of the rotating member 1013 to drive the swing member 1012 to swing, and then drives the pressing member 1011 to move, so that the pressing member 1011 can move towards the direction of the bottom of the mop bucket, and then the force applying part B of the pressing member 1011 can move towards the top of the mop head, thereby improving the extrusion efficiency.

[0149] In some embodiments, as shown in Figure 1 and 2 , the center of the swing member 1012 is arched away from the bottom of the bucket.

[0150] In the embodiment of the present application, the center of the swing member 1012 is arched away from the bottom of the bucket, which facilitates the sliding of the bottom end of the rotating member 1013 along the bottom of the bucket to drive the rotating member 1013 to rotate away from the bottom of the bucket, and then drive the swing member 1012 to swing, so that the end of the swing member 1012 connected with the pressing member 1011 can drive the pressing member 1011 to move towards the direction of the bottom of the bucket, and then drive the pressing member 1011 to effectively extrude the mop head.

[0151] In some embodiments, a specific implementation mode of the connection between the pressing member 1011 and the support module 102 is provided. As shown in Figure 1 , the pressing member 1011 is in sliding connection with the support module 102;

[0152] The swing of the swing member 1012 drives the pressing member 1011 to slide relative to the support module 102 towards the direction of the bottom of the bucket;

[0153] The sliding of the pressing member 1011 causes the force applying part B to apply force to the top of the mop head.

[0154] In the embodiment of the present application, the lower pressing piece 1011 and the support module 102 can be connected in sliding mode. When the swing piece 1012 swings to drive the lower pressing piece 1011 to slide relative to the support module 102 towards the direction of approaching the barrel bottom, the force applying part B of the lower pressing piece 1011 also applies force to the top of the mop head, so as to effectively extrude the mop head.

[0155] In some embodiments, a specific implementation of the sliding connection between the lower pressing piece 1011 and the support module 102 is provided. As shown in Figure 1 and 2 The support module 102 is provided with a sliding groove 1021 extending in the direction of approaching the barrel bottom, and the lower pressing piece 1011 is provided with a limiting protrusion 10112 which is matched with the sliding groove 1021. The swing piece 1012 swings to drive the limiting protrusion 10112 on the lower pressing piece 1011 to slide along the sliding groove 1021 in the direction of approaching the barrel bottom.

[0156] In the embodiment of the present application, the support module 102 is provided with a sliding groove 1021 extending in the direction of approaching the barrel bottom, and the limiting protrusion 10112 provided on the lower pressing piece 1011 can be matched with the sliding groove 1021. When the swing piece 1012 swings to drive the lower pressing piece 1011 to move, the limiting protrusion 10112 of the lower pressing piece 1011 will slide along the direction of the sliding groove 1021 in the direction of approaching the barrel bottom. Through the matched arrangement of the limiting protrusion 10112 and the sliding groove 1021, the moving direction of the lower pressing piece 1011 is effectively limited, and the moving direction of the force applying part B of the lower pressing piece 1011 is also limited, which helps the force applying part B to effectively extrude the mop head.

[0157] In some embodiments, as shown in Figure 1 and 2 The support module 102 is provided with a support block 1022 which abuts against the side of the lower pressing piece 1011 away from the swing piece 1012, for limiting the sliding direction of the lower pressing piece 1011.

[0158] In the embodiment of the present application, the support module 102 is provided with a support block 1022 which abuts against the side of the lower pressing piece 1011 away from the swing piece 1012. When the swing piece 1012 swings to drive the lower pressing piece 1011 to slide relative to the support module 102, the support block 1022 can limit the sliding direction of the lower pressing piece 1011 by abutting against the side wall of the lower pressing piece 1011, so as to facilitate the movement of the force applying part B of the lower pressing piece 1011 towards the top of the mop head, and then effectively extrude the mop head.

[0159] In some embodiments, as shown in Figure 1 and 2As shown, the support block 1022 is provided with a first inclined surface E near one side of the bucket bottom, and the pressing member 1011 is provided with a second inclined surface F;

[0160] When the pressing member 1011 slides towards the bucket bottom, the first inclined surface E is disengaged from the second inclined surface F; when the pressing member 1011 slides away from the bucket bottom to abut the first inclined surface E and continues to slide, the second inclined surface F slides along the first inclined surface E, so that the force applying part B of the pressing member 1011 rotates away from the support block 1022.

[0161] In the embodiments of the present application, when the user moves the mop head in the direction of the bucket bottom by pressing the mop head to drive the support module 102, the pressing member 1011 of the extrusion module 101 is driven to slide towards the bucket bottom. At this time, the second inclined surface F of the pressing member 1011 moves downward to disengage from the first inclined surface E on the support block 1022, as shown in the left extrusion module in Figure 1 In the embodiments of the present application, when the user moves the mop head in the direction of the bucket bottom by pressing the mop head to drive the support module 102, the pressing member 1011 of the extrusion module 101 is driven to slide towards the bucket bottom. At this time, the second inclined surface F of the pressing member 1011 moves downward to disengage from the first inclined surface E on the support block 1022, as shown in the left extrusion module in Figure 1 In the embodiments of the present application, when the user moves the mop head in the direction of the bucket bottom by pressing the mop head to drive the support module 102, the pressing member 1011 of the extrusion module 101 is driven to slide towards the bucket bottom. At this time, the second inclined surface F of the pressing member 1011 moves downward to disengage from the first inclined surface E on the support block 1022, as shown in the left extrusion module in

[0162] In some embodiments, a specific implementation of the pressing member 1011 is provided, as shown in Figure 1 and 2 As shown, the end of the pressing member 1011 away from the bucket bottom extends towards the end of the swinging member 1012 and is provided with a hook portion, and the hook portion forms the force applying part B of the pressing member 1011.

[0163] In the embodiments of the present application, the end of the pressing member 1011 away from the bucket bottom extends towards the end of the swinging member 1012 and is provided with a hook portion, i.e. the hook portion is arranged towards the top of the mop head. The hook portion forms the force applying part B of the pressing member 1011, and the hook portion can be used to extrude a larger area of the mop head, thereby improving the extrusion efficiency.

[0164] In some embodiments, a specific implementation of the squeezing device is provided. Figure 4 is a structural diagram of a support module in the squeezing device provided by the utility model, as Figure 4 shown, the support module 102 includes two oppositely arranged support parts 1023, and a receiving plate 1024 is arranged between the two support parts 1023.

[0165] The squeezing device includes two squeezing modules 101, and the two squeezing modules 101 are respectively arranged in connection with the two support parts 1023, so that the lower pressing parts 1011 of the two squeezing modules 101 are arranged on opposite sides of the receiving plate 1024.

[0166] The receiving plate 1024 is used for placing the mop head and moving towards the direction close to the barrel bottom under the driving of the mop head, thereby driving the two support parts 1023 to move towards the direction close to the barrel bottom.

[0167] In the embodiment of the application, the support module 102 includes two oppositely arranged support parts 1023, and a receiving plate 1024 is arranged between the two support parts 1023, and the mop head can be placed on the receiving plate 1024 for squeezing. In addition, the squeezing device includes two squeezing modules 101, and the two squeezing modules 101 are respectively arranged in connection with the two support parts 1023, so that the lower pressing parts 1011 of the two squeezing modules 101 are arranged on opposite sides of the receiving plate 1024. The receiving plate 1024 moves towards the direction close to the barrel bottom under the driving of the mop head, thereby driving the two support parts 1023 to move towards the direction close to the barrel bottom, and further driving the lower pressing parts 1011 of the two squeezing modules 101 to jointly squeeze the mop head, so as to effectively improve the squeezing efficiency. In addition, the two squeezing modules 101 independently squeeze the mop head, and when one of the squeezing modules 101 fails, the other squeezing module 101 can still squeeze the mop head, thereby improving the reliability of the squeezing device to a certain extent and prolonging the service life of the squeezing device.

[0168] In some embodiments, as Figure 4 shown, the support part 1023 has a mounting cavity, the lower pressing part 1011, the swinging part 1012 and the rotating part 1013 are arranged in the mounting cavity, and the bottom end A of the rotating part 1013 extends out of the mounting cavity and slides against the barrel bottom. The force applying part B of the lower pressing part 1011 extends out of the mounting cavity, so that when the mop head is placed on the support module 102, the force applying part B is located on the top of the mop head.

[0169] In the embodiment of the present application, the support part 1023 has a mounting cavity, and the lower pressing part 1011, the swinging part 1012 and the rotating part 1013 of the extrusion module 101 can be arranged in the mounting cavity. The bottom end A of the rotating part 1013 needs to extend out of the mounting cavity and slide against the bottom of the bucket. The force applying part B of the lower pressing part 1011 also needs to extend out of the mounting cavity and be located at the top position of the mop head, so as to facilitate the extrusion of the mop head. The arrangement of the mounting cavity limits the positions of the lower pressing part 1011, the swinging part 1012 and the rotating part 1013 in the extrusion device, and to some extent, the lower pressing part 1011, the swinging part 1012 and the rotating part 1013 and the related connection structure are not exposed, so that the lower pressing part 1011, the swinging part 1012 and the rotating part 1013 are not easily damaged due to pollution, collision and the like, and the stability and service life of the extrusion device are improved.

[0170] In some embodiments, as shown in Figures 1 to 4 The support part 1023 and the bottom of the bucket are provided with a reset part (not shown in the figure), which is used to drive the support module 102 to move away from the bottom of the mop bucket after the support module 102 is driven to move close to the bottom of the mop bucket, so as to reset, and then drive the rotating part 1013, the swinging part 1012 and the lower pressing part 1011 to reset.

[0171] In the embodiment of the present application, the support part 1023 and the bottom of the bucket are provided with a reset part. After the support module 102 is driven to move close to the bottom of the mop bucket, if the support module 102 is no longer driven, the reset part will drive the support module 102 to move away from the bottom of the mop bucket to reset, and then drive the rotating part 1013, the swinging part 1012 and the lower pressing part 1011 to reset, so that the extrusion device can continue to normally extrude the mop head.

[0172] In some embodiments, a specific implementation of the reset part is provided. The reset part is a spring. When the support module 102 is driven to move close to the bottom of the mop bucket, the spring is charged. When the spring is discharged, it drives the support module 102 to move away from the bottom of the mop bucket to reset.

[0173] In the embodiment of the present application, the reset part can be a spring. When the support module 102 is driven to move close to the bottom of the mop bucket, the spring is continuously charged. When the support module 102 is no longer driven, the discharge of the spring will drive the support module 102 to move away from the bottom of the mop bucket to reset, so as to facilitate the next extrusion operation. The spring as the reset part is simple and reliable, and has low cost.

[0174] In some embodiments, the bottom of the bucket has an arc surface, and when the support module 102 is driven to move towards the direction of the bottom of the bucket, the bottom end of the rotating piece 1013 slides along the arc surface to drive the rotating piece 1013 to rotate relative to the support module 102.

[0175] In the embodiments of the present application, the bottom of the bucket is provided with an arc surface, and when the support module 102 is driven to move towards the direction of the bottom of the bucket, the bottom end A of the rotating piece 1013 slides along the arc surface to drive the rotating piece 1013 to rotate relative to the support module 102. The arc surface facilitates smooth sliding of the bottom end A of the rotating piece 1013 thereon, thereby facilitating smooth extrusion of the extrusion module 101 on the mop head.

[0176] In some embodiments, the bottom of the bucket is provided with a containing groove, and the extrusion device is arranged in the containing groove, and the containing groove is used to isolate the extrusion device from the sewage deposited in the bucket.

[0177] In the embodiments of the present application, after the mop head is extruded and cleaned for multiple times, the bottom of the bucket is usually deposited with turbid sewage. If the extrusion device is immersed in the sewage for a long time, it is easy to cause the extrusion device to be difficult to operate normally. Therefore, the present application is provided with a containing groove at the bottom of the bucket, and the extrusion device can be arranged in the containing groove to isolate the extrusion device from the sewage deposited in the bucket, thereby effectively improving the stability and service life of the extrusion device.

[0178] In some embodiments, a specific implementation of the containing groove is provided. As shown in Figure 1 The mop bucket is provided with a shell 103, and the containing groove is recessed at one end of the shell 103 away from the bottom of the bucket.

[0179] In the embodiments of the present application, the shell 103 is clamped on the mop bucket, and the containing groove is recessed at one end of the shell 103 away from the bottom of the bucket. By clamping the shell 103, the containing cavity can be relatively fixed in the mop bucket, and the extrusion device can be relatively fixed in the mop bucket, so that the mop head is not easy to shake during extrusion, and the user can effectively extrude and clean the mop head.

[0180] In some embodiments, as shown in Figure 1 The bottom end A of the rotating piece 1013 is provided with a roller, and when the bottom end A of the rotating piece 1013 slides along the bottom of the bucket, the roller is driven to rotate.

[0181] In the embodiment of the present application, the bottom end A of the rotating member 1013 is provided with a roller, and the bottom end A of the rotating member 1013 slides along the bottom of the mop bucket through the roller, so that the friction of the bottom end A of the rotating member 1013 sliding on the bottom is small, facilitating smooth sliding of the bottom end A of the rotating member 1013 on the bottom, and further facilitating smooth extrusion of the mop head by the extrusion module 101.

[0182] According to another aspect, the embodiment of the present application also provides an extrusion device, as shown in Figure 1 The extrusion device is arranged in a mop bucket and used for extruding a mop head, and the extrusion device comprises two extrusion modules 101 and a support module 102, the support module 102 is used for placing the mop head and moving under the drive of the mop head; when the mop head is placed on the support module 102, the force applying part B of each extrusion module 101 is located at the top of the mop head;

[0183] When the support module 102 is driven to move towards the direction close to the bottom of the mop bucket, each extrusion module 101 is driven to move, and the force applying part B of each extrusion module 101 is driven to move towards the direction close to the support module 102 and apply force to the top of the mop head, so as to extrude the wiping material of the mop head between the force applying part B and the support module 102;

[0184] The two extrusion modules 101 are arranged at two opposite long sides of the mop head respectively.

[0185] In the extrusion device provided by the embodiment of the present application, the extrusion device comprises two extrusion modules 101 and a support module 102, the two extrusion modules 101 are arranged at two opposite long sides of the mop head respectively, and the two extrusion modules 101 support relatively independent work, when the user drives the support module 102 to move towards the direction of the bottom of the mop bucket by pressing the mop head, the force applying part of each extrusion module 101 moves towards the direction close to the support module 102 and applies force to the top of the mop head, so as to extrude the mop head. Since the two extrusion modules 101 support relatively independent extrusion of the mop head, when one of the two extrusion modules 101 fails to work, the normal work of the other extrusion module 101 is not affected, and the stability and service life of the extrusion device are improved to a certain extent.

[0186] In some embodiments, as shown in Figure 1 The force applying parts of the two extrusion modules 101 are arranged in space staggered manner, so that the extruded areas of the force applying parts B of the two extrusion modules 101 do not overlap when the wiping material of the mop head is extruded.

[0187] In the embodiment of the present application, the width of the mop head is usually set to be small, and the two extrusion modules 101 are arranged on the two opposite long sides of the mop head, so that the distance between the force applying parts of the two extrusion modules 101 is close, and the force applying parts of the two extrusion modules 101 are arranged in space staggered manner, avoiding the mutual influence of the two extrusion modules 101 when independently extruding the mop head, and such arrangement can enable each extrusion module 101 to achieve the effect of extruding the mop head as a whole to a certain extent, even if one of the extrusion modules 101 fails to use, because it will not affect the other extrusion module 101 to achieve the effect of extruding the mop head as a whole, effectively improving the stability and service life of the extrusion device.

[0188] It should be noted that the related implementation details of the extrusion device provided in the embodiment of the present application can refer to the related content of the extrusion device provided in any of the above embodiments, which will not be repeated here.

[0189] According to another aspect, the embodiment of the present application also provides an extrusion device, as shown in Figure 1 The extrusion device is used for extruding a mop head, and the extrusion device comprises a housing 103, an extrusion module 101 and a support module 102, the housing 103 is provided with a containing groove, and at least part of the extrusion module 101 is arranged in the containing groove; the extrusion device is fixedly arranged in a mop bucket through the housing 103;

[0190] The support module 102 is used for placing the mop head and moving under the drive of the mop head; when the mop head is placed in the support module 102, the force applying part B of the extrusion module 101 is located at the top of the mop head;

[0191] When the support module 102 is driven to move towards the bottom wall of the housing 103, the extrusion module 101 is driven to move, the extrusion module 101 drives the force applying part B to move towards the support module 102, and applies force to the top of the mop head, so as to extrude the wiping material of the mop head between the force applying part B and the support module 102.

[0192] The squeezing device provided by the embodiments of the present application comprises a shell 103, a squeezing module 101 and a supporting module 102, wherein the squeezing device is fixedly arranged in the mop bucket through the shell 103, so that the squeezing device can be relatively stably arranged in the mop bucket when a user uses the squeezing device to squeeze the mop head, thereby avoiding that the squeezing device moves in the mop bucket and affects the effective squeezing of the mop head. In addition, after the mop head is squeezed and cleaned for multiple times, turbid sewage is usually deposited on the bottom of the mop bucket. If the squeezing device is immersed in the sewage for a long time, the squeezing device is prone to fail to normally operate. Therefore, the shell 103 is provided with a containing groove, and at least part of the squeezing module 101 is arranged in the containing groove, so as to isolate the squeezing device from the sewage deposited in the mop bucket, thereby effectively improving the stability and service life of the squeezing device.

[0193] It should be noted that the related implementation details of the squeezing device provided by the embodiments of the present application can refer to the related content of the squeezing device provided by any of the above embodiments, which will not be described herein.

[0194] According to another aspect, the embodiments of the present application also provide a squeezing device, as shown in Figure 1 The squeezing device is arranged in the mop bucket and used for squeezing the mop head. The squeezing device comprises a squeezing module 101 and a supporting module 102. The supporting module 102 is used for placing the mop head and moving under the driving of the mop head.

[0195] The squeezing module 101 comprises a pressing piece 1011 and a rotating piece 1013 in transmission connection with the pressing piece 1011. The rotating piece 1013 is in rotational connection with the supporting module 102. The pressing piece 1011 is in sliding connection with the supporting module 102. The rotational connection position of the rotating piece 1013 and the supporting module 102 is arranged in a staggered manner with the sliding connection position of the pressing piece 1011 and the supporting module 102.

[0196] When the mop head is placed in the supporting module 102, the force applying part B of the pressing piece 1011 is located at the top of the mop head. When the supporting module 102 is driven to move towards the bottom of the mop bucket, the bottom end of the rotating piece 1013 slides along the bottom of the mop bucket, drives the rotating piece 1013 to rotate relative to the supporting module 102, and the rotating piece 1013 drives the pressing piece 1011 to slide relative to the supporting module 102 towards the bottom of the mop bucket.

[0197] The pressing piece 1011 slides the force applying part B to apply a force to the top of the mop head, so as to squeeze the wiping material of the mop head located between the force applying part B and the supporting module 102.

[0198] The rotating part 1013 of the extrusion module 101 and the rotating connection position of the support module 102 and the sliding connection position of the lower pressing part 1011 of the extrusion module 101 and the support module 102 are arranged in a staggered manner, so that when the mop head is pressed, the force applied by the extrusion module 101 to the support module 102 is divided into two force application areas, that is, the area where the rotating connection position is located and the area where the sliding connection position is located, effectively ensuring the stability of the working of the extrusion module 101. Even if the force applied by the extrusion module 101 to the support module 102 is large, the decomposition into two force application areas will also have the effect of unloading, and will not cause the extrusion module 101 and the support module 102 to be damaged due to the large force, thereby prolonging the service life of the extrusion device to a certain extent.

[0199] In some embodiments, a specific implementation of the extrusion module 101 is provided, as shown in Figure 1 The extrusion module 101 further comprises a swing part 1012, the lower pressing part 1011 and the rotating part 1013 are drivingly connected through the swing part 1012, and the two ends of the swing part 1012 are movably connected with the lower pressing part 1011 and the rotating part 1013 respectively, so that the rotating part 1013 and the rotating connection position of the support module 102 and the sliding connection position of the lower pressing part 1011 and the support module 102 are arranged in a staggered manner.

[0200] When the support module 102 is driven to move towards the direction of the bottom of the mop bucket, the bottom end A of the rotating part 1013 slides along the bottom of the mop bucket to drive the rotating part 1013 to rotate relative to the support module 102, the rotating of the rotating part 1013 drives the swing part 1012 to swing, and the swinging of the swing part 1012 drives the lower pressing part 1011 to slide relative to the support module 102 towards the direction of the bottom of the mop bucket.

[0201] In the embodiments of the present application, the extrusion module 101 further comprises a swing part 1012, when the support module 102 is driven to move towards the direction of the bottom of the mop bucket, the bottom end A of the rotating part 1013 slides along the bottom of the mop bucket to drive the rotating part 1013 to rotate relative to the support module 102, and the rotating of the rotating part 1013 drives the swing part 1012 to swing, and the swinging of the swing part 1012 drives the lower pressing part 1011 to slide relative to the support module 102 towards the direction of the bottom of the mop bucket, and the force application part B of the lower pressing part 1011 is lowered to effectively extrude the mop head.

[0202] It should be noted that the related implementation details of the extrusion device provided in the embodiments of the present application can refer to the related content of the extrusion device provided in any of the above embodiments, which will not be repeated here.

[0203] The following illustrates the squeezing device provided by the embodiments of the present application.

[0204] In the related art, the squeezing mechanism of the mop head usually has the following problems:

[0205] 1) Since water is needed to be contained in the barrel for cleaning the mop, the water will become turbid after the mop is cleaned for many times, and the transmission part of the whole squeezing mechanism is usually immersed in the sewage, which can easily cause the squeezing mechanism to be stuck by stains, or the guide groove on the barrel to be blocked by stains, so that the transmission cannot normally operate.

[0206] 2) The two force applying and squeezing components usually located on the same side need to be simultaneously lowered by the same lever, and if the lever is damaged, one end of the mop head cannot be squeezed.

[0207] 3) The two lever assemblies of the squeezing mechanism need to be rotationally connected with the squeezing bottom plate, that is, the force between any one lever and the squeezing bottom plate is concentrated on one rotation shaft, and if the user applies a large force, the rotation shaft can be damaged, and thus the whole squeezing mechanism cannot be used.

[0208] In view of the above problems, the embodiments of the present application provide a squeezing device, as shown in Figure 1 and Figure 2 The squeezing device is provided with a squeezing module 101 at both ends of the barrel of the mop barrel, and a squeezing bottom plate (i.e. the above-mentioned receiving plate 1024) is arranged between the two squeezing modules 101. The two ends of the squeezing bottom plate can be fixedly or detachably connected with the squeezing bottom plate support (for example, the above-mentioned support part 1023), and the detachable squeezing bottom plate can be replaced.

[0209] For the squeezing module 101, the top end of the lower pressing piece 1011 has a pressing end (i.e. the above-mentioned force applying part B), the lower end of the lower pressing piece 1011 is slidingly connected with the support module 102 through the sliding groove 1021, and the lower end of the lower pressing piece 1011 is rotationally connected with one end of the swing piece 1012 (achieved by a curved connecting rod), the other end of the swing piece 1012 is rotationally connected with the middle segment of the rotating piece 1013 (achieved by a movable connecting rod), one end of the rotating piece 1013 is rotationally connected with the support module 102, and the other end is slidingly connected with the guide curved surface at the bottom of the shell 103 through the roller.

[0210] When the user needs to squeeze the water of the cleaned rubber cotton head, the rubber cotton head can be placed on the receiving plate 1024 and downward force is applied, the receiving plate 1024 is lowered, the bottom end A of the rotating piece 1013 is swung along the guide curved surface of the shell 103 to the side wall of the barrel through the roller, the rotating of the rotating piece 1013 drives the swing piece 1012 to move, and the swing piece 1012 drives the lower pressing piece 1011 to move downward along the sliding groove 1021 relative to the support module 102.

[0211] The downward movement of the pressing member 1011 causes the force applying part B to move towards the receiving plate 1024, so that the distance between the force applying part B and the receiving plate 1024 is reduced, and the sponge head is pressed to squeeze water out of the sponge head.

[0212] In addition, a reset spring is arranged between the lower end of the supporting part 1023 of the supporting module 102 and the shell 103, and after the pressing is completed, the user stops applying force, the receiving plate 1024 and the supporting module 102 are moved upward and reset under the action of the reset spring, and the pressing module 101 is also reset.

[0213] When the supporting module 102 is reset, the rotating member 1013 swings towards the bottom of the barrel, and then the swinging member 1012 drives the pressing member 1011 to move upward, and when the pressing member 1011 moves upward, the first inclined surface E abuts against the second inclined surface F, and the abutment of the first inclined surface E against the second inclined surface F causes the force applying part B of the pressing member 1011 to move away from the receiving plate 1024, so that after the receiving plate 1024 is reset, the top ends of the two pressing members 1011 arranged oppositely are slightly opened, facilitating the taking out and re-putting of the sponge head.

[0214] According to another aspect, the application also provides a mop barrel, comprising:

[0215] a barrel;

[0216] The pressing device as described in any of the above embodiments is arranged in the barrel.

[0217] In some embodiments, the mop barrel comprises two pressing devices, and one pressing device is arranged on each side along the length direction of the barrel.

[0218] In the application, two pressing devices can be arranged in the mop barrel, and the two pressing devices are arranged along the length direction of the barrel to effectively press the left and right sides of the long side of the mop head, thereby improving the pressing efficiency.

[0219] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the application, but not to limit them; although the application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the application.
