Description

Technical Field

[0001] The utility model relates to the technical field of daily household cleaning, in particular to a rotary mop. Background Art

[0002] In the prior art, for a rotary mop, in order to achieve labor-saving during cleaning and high speed during dehydration, a planetary gear needs to be installed in the mop tray. During cleaning, the sun gear fixedly connected to the lower rod of the mop rod meshes with the planetary gear, which has the effect of reducing the rotation speed. That is, when the displacement of the upper rod is the same during cleaning, the speed of rotation of the mop tray is lower, which is more labor-saving. During dehydration, the sun gear is disengaged from the planetary gear. At this time, when the displacement of the upper rod is the same during cleaning, the speed of rotation of the mop tray is higher, achieving the purpose of rapid dehydration. However, the rotary mop in the prior art uses more gears, has a more complex structure, is more expensive, is easily damaged, and also makes the mop tray larger in size, which is inconvenient to use and store. Utility Model Content

[0003] In view of this, the utility model provides a rotary mop to solve the problems in the prior art that the rotary mop uses more gears, has a higher cost, is larger in size, and is easily damaged.

[0005] An upper rod assembly, comprising a spiral rod driven to move along the axial direction of the mop rod;

[0006] The lower rod assembly includes a rotating cylinder connected to the mop head, and the end of the spiral rod extends into the rotating cylinder;

[0007] A first driving structure is arranged between the rotating cylinder and the spiral rod, and the first driving structure is in transmission cooperation with the spiral rod;

[0008] The second driving structure is arranged on the end of the spiral rod and can move along the axial direction of the mop rod with the spiral rod. A spiral guide groove is arranged on one of the outer wall of the second driving structure and the inner wall of the rotating cylinder, and a guide part is arranged on the other. The guide part extends into the spiral guide groove and moves along the spiral guide groove.

[0009] Wherein, the helical angle of the spiral rod is different from the helical angle of the spiral guide groove;

[0010] The rotary mop has a first state in which the first driving structure is connected to the rotating drum in a transmission manner and a second state in which the first driving structure is disconnected from the rotating drum in a transmission manner:

[0011] When the rotary mop is in the first state and the spiral rod moves along the axial direction of the mop rod toward the mop head, the rotary cylinder drives the mop head to rotate at a first speed under the drive of the first driving structure;

[0012] When the rotary mop is in the second state and the spiral rod moves along the axial direction of the mop rod toward the mop head, the rotating cylinder drives the mop head to rotate at a second speed under the drive of the second driving structure, the first speed is determined by the spiral angle of the spiral rod, and the second speed is determined by the spiral angle of the spiral guide groove.

[0013] Beneficial effect: The mop rod adopts the design of the spiral rod and the first driving structure matched with the transmission, and the rotating cylinder and the second driving structure matched with the spiral guide groove and the guide part, which can realize the driving of the mop head to rotate, and the structure is simpler, more compact, small in size, low in cost, convenient to use and store, and the transmission method is simpler, more reliable and more stable. In addition, the spiral rod and the spiral guide groove are designed with different spiral angles, which can achieve the effect of speed difference when the mop head rotates, so as to facilitate the switching of high and low speeds when washing and drying the mop head, so as to achieve the effect of labor saving when washing and fast speed when dehydrating, and effectively solve the problem that the rotary mop in the prior art installs planetary gears in the mop plate, which has a more complex structure, higher cost, and is easy to damage, making the mop plate larger in size and inconvenient to use and store.

[0016] In an optional embodiment, the first driving structure has a cylindrical body, and the outer peripheral wall of the cylindrical body is provided with first meshing teeth.

[0017] Beneficial effect: By constructing the first meshing teeth on the outer peripheral wall of the cylindrical body of the first driving structure, no additional axial space of the first driving structure is occupied, making the overall structure more compact and small, and compared with setting the first meshing teeth at other positions such as the end of the cylindrical body, setting the first meshing teeth on the outer peripheral wall of the cylindrical body has higher strength and stability and is not easy to be damaged.

[0018] In an optional embodiment, the first driving structure is provided with a spiral groove cooperating with the spiral rod;

[0019] When the spiral rod is inserted into the spiral groove and moves along the axial direction of the mop rod, it can drive the first driving structure to rotate at the first speed.

[0022] The clutch structure is movably arranged on the spiral rod and is used to control the rotary mop to switch between a first state and a second state.

[0023] Beneficial effect: Through the clutch structure movably arranged on the spiral rod, the clutch structure can control the first driving structure and the rotating drum to be connected or disconnected from each other, so as to facilitate the control of the rotating mop to switch between the first state and the second state, thereby realizing the high and low speed switching of the rotating mop.

[0024] In an optional embodiment, the clutch structure has a braking state and a releasing state;

[0025] When the clutch structure is in a braking state, the clutch structure is locked with the rotating drum and can limit the position of the first driving structure to prevent the first driving structure from being in driving connection with the rotating drum;

[0026] When the clutch structure is in a released state, the clutch structure is disengaged from the rotating cylinder and the restriction on the first driving structure is released.

[0027] Beneficial effect: When the clutch structure is in a braking state, the clutch structure can be locked with the rotating drum, and can limit the displacement of the first driving structure by abutting with the first driving structure to prevent the first driving structure from being transmission-connected with the rotating drum, so that the rotating drum can only rotate under the drive of the second driving structure; when the clutch structure is in a released state, the clutch structure is disengaged from the rotating drum, and the restriction on the first driving structure is released, so that the first driving structure can move to a position transmission-connected with the rotating drum under the drive of the spiral rod, and can drive the rotating drum to rotate, so that the rotating drum can rotate under the drive of the first driving structure.

[0032] Beneficial effect: The clutch structure adopts the design of a limiting part and a locking part, a first engaging part is provided on the locking part, and a second engaging part is provided on the rotating cylinder. When the clutch structure is in a braking state, the first engaging part and the second engaging part can engage with each other to form a limit in the axial direction of the mop rod, so that the clutch structure cannot move along the spiral rod, thereby providing a more reliable and stable support limit for the first drive structure, so that the first drive structure cannot move to a position engaged with the rotating cylinder.

[0033] In an optional embodiment, the clutch structure can rotate relative to the rotating cylinder in a set unlocking direction and locking direction under the drive of the upper rod assembly, and the unlocking direction and the locking direction are opposite to each other;

[0034] When the clutch structure rotates along the locking direction driven by the upper rod assembly, the first engaging member and the second engaging member engage with each other;

[0035] When the clutch structure rotates along the unlocking direction driven by the upper rod assembly, the first engaging member and the second engaging member are disengaged.

[0036] Beneficial effect: by operating the upper rod assembly to drive the clutch structure to rotate forward or reversely, the first engaging member and the second engaging member can be engaged or disengaged, and the control is relatively convenient. When the first engaging member and the second engaging member are engaged, the rotating drum and the clutch structure are locked, and the clutch structure can provide a stable and reliable limit to the first driving structure, so that the first driving structure cannot move in the axial direction of the mop rod to engage with the rotating drum; when the first engaging member and the second engaging member are disengaged, the rotating drum and the clutch structure are unlocked, and the clutch structure can move in the axial direction of the mop rod with the first driving structure, thereby releasing the restriction on the first driving structure, so that the first driving structure can move to a position engaged with the rotating drum under the drive of the spiral rod, thereby realizing the transmission connection between the first driving structure and the rotating drum.

[0040] Beneficial effect: Through the cooperation of the above-mentioned multiple first hooks and second hooks, the clutch structure is more stable in cooperation with the rotating cylinder when in a braking state, forming a uniform, stable and reliable limiting connection in the circumferential direction, which is not easy to fall off and separate, and has a better locking effect.

[0041] In an optional embodiment, a first slot into which the second hook can extend is formed between two adjacent first hooks, and a second slot into which the first hook can extend is formed between two adjacent second hooks;

[0043] The avoidance portion is used to avoid the movement of the first hook and the second hook when the clutch structure rotates along the unlocking direction, so that the first hook can escape from the second slot and the second hook can escape from the first slot.

[0044] Beneficial effect: The first hook and the second hook can form a good engagement effect when the clutch structure and the rotating cylinder are locked through the respectively arranged bent hook parts, and can be more easily disengaged when the clutch structure and the rotating cylinder are unlocked through the respectively arranged avoidance parts to avoid getting stuck.

[0045] In an optional embodiment, the first engaging member is fixedly disposed on a side wall of the supporting body close to the first driving structure.

[0046] Beneficial effect: By fixing the first engaging member on the side wall of the supporting body close to the first driving structure, it is more convenient to cooperate with the second engaging member, while also avoiding affecting the cooperation between the subsequent clutch structure, the transmission member and the second driving structure.

[0047] In an optional embodiment, the rotating drum comprises:

[0048] The inner cylinder is arranged along the axial direction of the mop rod, and the inner cylinder includes a first cylinder body and a second cylinder body which are sequentially arranged from a direction away from the mop head to a direction close to the mop head;

[0050] Beneficial effect: The inner cylinder adopts a two-piece design of a first cylinder body and a second cylinder body, which is more convenient for assembly and also convenient for setting structures such as the second meshing teeth, the second engaging member, and the spiral guide groove.

[0051] In an optional embodiment, the rotating cylinder is provided with second meshing teeth for transmission connection with the first driving structure, and the second meshing teeth are arranged on the inner periphery of one end of the first cylinder close to the second cylinder.

[0052] Beneficial effect: By arranging the second meshing tooth on the inner circumference of the first cylinder, no additional space in the axial direction of the first cylinder will be occupied, and it is more convenient to cooperate with the first meshing tooth. The second meshing tooth is arranged at one end close to the second cylinder, that is, at the lower end of the first cylinder, so that when the upper rod assembly is pressed down to drive the first driving structure to move downward, it can engage with the second meshing tooth at the lower end of the first cylinder.

The outer cylinder is set to connect and fix the first cylinder body and the second cylinder body, and can be covered outside the first cylinder body and the second cylinder body, thereby improving the aesthetics of the overall structure.

[0058] In an optional embodiment, the upper rod assembly further includes:

[0059] The transmission member is fixedly arranged at one end of the spiral rod extending into the rotating cylinder, and the transmission member includes a transmission part and a rod body part, and the rod body part is fixedly arranged on a side of the transmission part close to the mop head; the second driving structure is movably sleeved on the rod body part, and the second driving structure is limited on the rod body part in the axial direction of the mop rod;

[0060] When the spiral rod moves along the axial direction of the mop rod toward the mop head, the transmission part abuts against the second driving structure and can drive the second driving structure to move along the axial direction of the mop rod, so that the guide part provided on the second driving structure can slide in the spiral guide groove in the rotating cylinder to drive the rotating cylinder to rotate.

[0061] Beneficial effect: By arranging a transmission part on the end of the spiral rod and movably sleeved the second driving structure on the rod body, when the spiral rod moves along the axial direction of the mop rod toward the mop head, the transmission part can abut against the second driving structure, thereby clamping the second driving structure and driving the second driving structure to move downward, so that the guide part arranged on the second driving structure can slide in the spiral guide groove in the rotating cylinder, thereby driving the rotating cylinder to rotate.

[0062] In an optional embodiment, a first limiting tooth is provided at one end of the transmission part close to the second driving structure, and a first matching groove is provided on the second driving structure corresponding to the first limiting tooth;

[0063] When the spiral rod moves along the axial direction of the mop rod toward the mop head, the first limiting tooth extends into the first matching groove, so that the transmission member and the second driving structure are limited in the circumferential direction of the mop rod.

[0064] Beneficial effect: Through the design of the first limiting tooth and the first matching groove, the transmission member can not only push the second drive structure to move in the axial direction of the mop rod, but also when the spiral rod drives the transmission member to move down to the extreme position, the transmission member and the second drive structure are locked in the circumferential direction.

[0065] In an optional embodiment, the first limiting tooth and the first matching groove are matched through straight surfaces on one side and through inclined surfaces on the other side in the circumferential direction of the mop rod.

[0066] Beneficial effect: The first limit tooth and the first matching groove adopt a method of matching with a straight surface on one side and a bevel surface on the other side, so that the second cylinder can in turn drive the second drive structure to rotate around the spiral rod when it rotates. Since the second drive structure and the transmission member are slipped through the bevel guide, the transmission member can be effectively prevented from getting stuck in the second drive structure, thereby also preventing the second cylinder from getting stuck.

[0067] In an optional embodiment, the upper rod assembly further includes a limiting structure, which is fixedly disposed on the rod body and is used to limit the second driving structure to prevent the second driving structure from being separated from the transmission member.

[0068] Beneficial effect: By means of the limiting structure provided on the rod body, the second driving structure can be effectively prevented from being separated from the transmission member, so that the second driving structure and the spiral rod can achieve stable transmission cooperation through the transmission member.

[0069] In an optional embodiment, an elastic deformation portion is provided at the end of the rod body, and the limiting structure is a limiting ring;

[0070] When the limiting ring is sleeved into the elastic deformation part, the elastic deformation part is closed, so that the limiting ring passes through the elastic deformation part and is sleeved on the rod body;

[0071] When the limiting ring passes through the elastic deformation portion, the elastic deformation portion opens to prevent the limiting ring from being separated from the rod body portion.

[0072] Beneficial effect: The elastic deformation part is arranged at the end of the rod body, which can shrink inwards when squeezed by the limiting ring, thereby facilitating the assembly of the limiting ring onto the rod body. After the limiting ring is assembled onto the rod body, the elastic deformation part can expand outwards and restore the deformation under the action of its own elastic force, thereby limiting the limiting ring on the rod body and preventing the limiting ring from detaching from the rod body. The elastic deformation part is arranged to facilitate the assembly of the limiting ring and effectively prevent the limiting ring from detaching from the rod body.

[0073] In an optional embodiment, the transmission member is located between the clutch structure and the second driving structure of the rotary mop;

[0113] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0114] Combine the following Figures 1 to 15 , describing an embodiment of the utility model.

[0115] According to an embodiment of the utility model, on the one hand, the utility model provides a rotary mop, including a mop rod 100 and a mop head 200 arranged at one end of the mop rod 100, and the mop rod 100 includes an upper rod assembly 10, a lower rod assembly 20, a first driving structure 30, and a second driving structure 40. The upper rod assembly 10 includes a spiral rod 11 driven to move along the axial direction of the mop rod 100; the lower rod assembly 20 includes a rotating cylinder 21 connected to the mop head 200, and the end of the spiral rod 11 extends into the rotating cylinder 21; the first driving structure 30 is arranged between the rotating cylinder 21 and the spiral rod 11, and the first driving structure 30 is in transmission cooperation with the spiral rod 11; the second driving structure 40 is arranged on the end of the spiral rod 11, and can move along the axial direction of the mop rod 100 with the spiral rod 11, and the outer wall of the second driving structure 40 and the inner wall of the rotating cylinder 21 are provided with a spiral guide groove 210, and the other is provided with a guide part 41, and the guide part 41 extends into the spiral guide groove 210 and moves along the spiral guide groove 210; wherein the spiral angle of the spiral rod 11 is different from the spiral angle of the spiral guide groove 210.

[0116] Further, the rotary mop has a first state in which the first driving structure 30 is transmission-connected to the rotary drum 21 and a second state in which the first driving structure 30 is transmission-disconnected from the rotary drum 21: when the rotary mop is in the first state and the spiral rod 11 moves in a direction close to the mop head 200 along the axial direction of the mop rod 100, the rotary drum 21 drives the mop head 200 to rotate at a first speed under the drive of the first driving structure 30; when the rotary mop is in the second state and the spiral rod 11 moves in a direction close to the mop head 200 along the axial direction of the mop rod 100, the rotary drum 21 drives the mop head 200 to rotate at a second speed under the drive of the second driving structure 40, and the first speed is determined by the spiral rod 11. The second speed is determined by the spiral angle of the spiral guide groove 210. Specifically, in the first state, since the first driving structure 30 is in transmission cooperation with the spiral rod 11, and the two are in spiral cooperation, and the first driving structure 30 is in transmission connection with the rotating cylinder 21, when the spiral rod 11 is driven to press down a distance h, the spiral rod 11 rotates a circle, and then drives the rotating cylinder 21 to rotate a circle, so that the mop head 200 rotates at the first speed. As is known to all, the spiral angle is the acute angle between the tangent of the cylindrical spiral line and the straight generatrix of the cylindrical surface passing through the tangent point, so the value of a is related to the spiral angle of the spiral rod 11, that is, the first speed is determined by the spiral angle of the spiral rod 11.

[0117] In the second state, since the first driving structure 30 is disengaged from the rotating cylinder 21, that is, in the second state, the rotation of the rotating cylinder 21 is not affected by the first driving structure 30. At the same time, since the second driving structure 40 cooperates with the screw rod 11, and the second driving structure 40 is driven by the screw rod 11 to move axially, and the second driving structure 40 cooperates with the rotating cylinder 21 through the spiral guide groove 210 and the guide part 41, when the screw rod 11 is driven to press down a distance h, the second driving structure 40 is driven to move downward a distance h, and the guide part is synchronously driven to rotate b circles, thereby driving the rotating cylinder 21 Rotate b circles so that the mop head 200 rotates at the second speed. Usually, the value of b is related to the spiral angle of the spiral guide groove 210, that is, the second speed is determined by the spiral angle of the spiral guide groove 210. In the two states, when the spiral rod 11 is driven down a certain distance, the number of rotations of the rotating cylinder 21 is different, and the first speed and the second speed are also different, so that the user can adjust the number of rotations of the rotating cylinder 21 by adjusting the spiral angle of the spiral rod 11 or the spiral angle of the spiral guide groove 210, and then adjust the first speed or the second speed to meet the different usage requirements of the user.

[0118] In the above embodiment, the mop rod 100 can achieve the design of driving the mop head 200 to rotate by adopting the design of the spiral rod 11 and the first driving structure 30 that are matched with the transmission, and the rotating cylinder 21 and the second driving structure 40 that are matched with the spiral guide groove 210 and the guide part 41, while the structure is simpler, more compact, smaller, and less expensive, and convenient to use and store, and the transmission method is simpler, more reliable, and more stable. In addition, the spiral rod 11 and the spiral guide groove 210 are designed with different spiral angles, which can achieve the effect of speed difference when the mop head 200 rotates, so as to facilitate the high and low speed switching when washing and drying the mop head 200, so as to achieve the effect of labor saving when washing and fast speed when dehydrating, and effectively solve the problem that the rotary mop in the prior art installs planetary gears in the mop plate, which is more complicated in structure, more expensive, and easy to damage, making the mop plate larger in size, and inconvenient to use and store.

[0119] Specifically, in this embodiment, the first state is the spin-drying state, and the second state is the cleaning state. The spiral angle of the spiral rod 11 is smaller than the spiral angle of the spiral guide groove 210, and the first rotational speed is greater than the second rotational speed. By controlling the first driving structure 30 to be connected or disconnected from the rotating drum 21, the rotational speed of the mop head 200 is adjusted to achieve switching between the cleaning state and the spin-drying state, so that the user does not need to stop the rotation of the mop head 200 when switching states, and the switching from the cleaning state to the spin-drying state is smoother and easier to operate; and the cleaning state corresponds to the low-speed rotation of the mop, which can ensure the water spraying amount and friction cleaning time of the mop, thereby ensuring the cleaning effect of the mop, and the spin-drying state corresponds to the high-speed rotation of the mop, which can use centrifugal force to ensure that the water on the mop is fully dried.

[0120] In some embodiments, the first driving structure 30 is sleeved on the spiral rod 11, and the first driving structure 30 is provided with a first meshing tooth 31, and the rotating cylinder 21 is provided with a second meshing tooth 211; the first driving structure 30 is used to move to a position where the first meshing tooth 31 and the second meshing tooth 211 are meshed under the drive of the spiral rod 11, so that the rotary mop is in the first state, so that the first driving structure 30 drives the rotating cylinder 21 to rotate.

[0121] In the above embodiment, by sleeve-mounting the first driving structure 30 on the spiral rod 11, and by providing the first meshing teeth 31 on the first driving structure 30 and the second meshing teeth 211 on the rotating cylinder 21, the first driving structure 30 can mesh with the rotating cylinder 21 during the movement, thereby facilitating the switching of the first driving structure 30 to drive the rotating cylinder 21 to rotate. The first driving structure 30 and the rotating cylinder 21 realize meshing transmission connection or disengagement transmission connection by adopting the provided meshing teeth, and the transmission method is simple and reliable.

[0122] In some embodiments, the first driving structure 30 has a cylindrical body, and the outer peripheral wall of the cylindrical body is provided with first meshing teeth 31 .

[0123] In the above embodiment, by constructing the first meshing tooth 31 on the outer peripheral wall of the cylindrical body of the first driving structure 30, no additional axial space of the first driving structure 30 is occupied, so that the overall structure is more compact and small, and compared with setting the first meshing tooth 31 at other positions such as the end of the cylindrical body, setting the first meshing tooth 31 on the outer peripheral wall of the cylindrical body has higher strength and stability and is not easy to be damaged.

[0124] Specifically, in this embodiment, the spiral rod 11 is a twisted rod, and the first meshing teeth 31 can be integrally formed on the outer peripheral wall of the cylindrical body by injection molding, cutting and other processes. There are multiple first meshing teeth 31, and the multiple first meshing teeth 31 are arranged in sequence along the circumference of the cylindrical body.

[0125] In an optional embodiment, the first driving structure 30 is provided with a spiral groove cooperating with the spiral rod 11; when the spiral rod 11 is inserted into the spiral groove and moves along the axial direction of the mop rod 100, it can drive the first driving structure 30 to rotate at the first speed.

[0126] In the above embodiment, the spiral groove is provided in the first driving structure 30 , and the transmission cooperation between the spiral groove and the spiral rod 11 is utilized to realize the conversion of the axial movement of the spiral rod 11 in the mop rod 100 into the rotational movement of the first driving structure 30 .

[0127] In this embodiment, the first driving structure is formed by opening a hole inside a solid column. Specifically, a spiral groove matching the outer circumference of the spiral rod is opened inside the column. The spiral groove is located at the center of the column and passes through the column. The column after the hole is opened constitutes the above-mentioned tubular body.

[0128] In some embodiments, the rotary mop further includes a clutch structure 50 , which is movably disposed on the spiral rod 11 and is used to control the rotary mop to switch between the first state and the second state.

[0129] In the above embodiment, by means of the clutch structure 50 movably arranged on the spiral rod 11, the clutch structure 50 can control the first driving structure 30 and the rotating drum 21 to be connected or disconnected from each other, thereby facilitating the control of the rotating mop to switch between the first state and the second state, thereby realizing the high and low speed switching of the rotating mop.

[0130] In some embodiments, the clutch structure 50 has a braking state and a releasing state; when the clutch structure 50 is in the braking state, the clutch structure 50 is locked with the rotating cylinder 21 and can limit the position of the first drive structure 30 to prevent the first drive structure 30 from being transmission-connected with the rotating cylinder 21; when the clutch structure 50 is in the releasing state, the clutch structure 50 is disengaged from the rotating cylinder 21 and the restriction on the first drive structure 30 is released.

[0131] In the above embodiment, when the clutch structure 50 is in a braking state, the clutch structure 50 can be locked with the rotating cylinder 21, and can limit the displacement of the first driving structure 30 by abutting against the first driving structure 30 to prevent the first driving structure 30 from being transmission-connected to the rotating cylinder 21, so that the rotating cylinder 21 can rotate only under the drive of the second driving structure 40. When the clutch structure 50 is in a released state, the clutch structure 50 is disengaged from the rotating cylinder 21, and the restriction on the first driving structure 30 is released, so that the first driving structure 30 can be moved to a position transmission-connected with the rotating cylinder 21 under the drive of the spiral rod 11, and can drive the rotating cylinder 21 to rotate, so that the rotating cylinder 21 can rotate under the drive of the first driving structure 30.

[0132] In some embodiments, the clutch structure 50 includes a limiting portion 51 and a locking portion 52, wherein the limiting portion 51 is cylindrical, the limiting portion 51 is slidably mounted on the spiral rod 11, and one end is suitable for abutting against the first drive structure 30; the locking portion 52 includes a supporting body 521 fixedly arranged at one end of the limiting portion 51 away from the first drive structure 30, and a first engaging member 522 fixedly arranged on the supporting body 521; a second engaging member 212 is arranged on the rotating cylinder 21 corresponding to the first engaging member 522, and when the clutch structure 50 is in a braking state, the first engaging member 522 and the second engaging member 212 are engaged with each other, and the limiting portion 51 supports the first drive structure 30 to limit the first drive structure 30.

[0133] In the above embodiment, the clutch structure 50 adopts the design of the limiting portion 51 and the locking portion 52, the locking portion 52 is provided with a first engaging member 522, and the rotating cylinder 21 is provided with a second engaging member 212. When the clutch structure 50 is in a braking state, the first engaging member 522 and the second engaging member 212 can engage with each other to form a limit in the axial direction of the mop rod 100, so that the clutch structure 50 cannot move along the spiral rod 11, thereby providing a more reliable and stable support limit for the first driving structure 30, so that the first driving structure 30 cannot move to a position engaged with the rotating cylinder 21.

[0134] In this embodiment, when the clutch structure 50 is in a released state, when the first drive structure 30 moves downward driven by the spiral rod 11, the first meshing teeth 31 on the first drive structure 30 can mesh with the second meshing teeth 211 on the rotating cylinder 21. When the clutch structure 50 is in a braking state, the first drive structure 30 cannot move upward, and the first meshing teeth 31 on the first drive structure 30 cannot mesh with the second meshing teeth 211 on the rotating cylinder 21, thereby realizing the separation of the first drive structure 30 from the rotating cylinder 21.

[0135] In some embodiments, the clutch structure 50 can rotate in a set unlocking direction and locking direction relative to the rotating cylinder 21 under the drive of the upper rod assembly 10, and the unlocking direction and the locking direction are opposite to each other; when the clutch structure 50 rotates along the locking direction under the drive of the upper rod assembly 10, the first engaging member 522 and the second engaging member 212 engage; when the clutch structure 50 rotates along the unlocking direction under the drive of the upper rod assembly 10, the first engaging member 522 and the second engaging member 212 disengage.

[0136] In the above embodiment, by operating the upper rod assembly 10 to drive the clutch structure 50 to rotate forward or reversely, the first engaging member 522 and the second engaging member 212 can be engaged or disengaged, and the control is relatively convenient. When the first engaging member 522 and the second engaging member 212 are engaged, the rotating cylinder 21 is locked with the clutch structure 50, and the clutch structure 50 can provide a stable and reliable limit for the first driving structure 30, so that the first driving structure 30 cannot move in the axial direction of the mop rod 100 to engage with the rotating cylinder 21; when the first engaging member 522 and the second engaging member 212 are disengaged, the rotating cylinder 21 is unlocked from the clutch structure 50, and the clutch structure 50 can move in the axial direction of the mop rod 100 with the first driving structure 30, thereby releasing the restriction on the first driving structure 30, so that the first driving structure 30 can be driven by the spiral rod 11 to move to a position engaged with the rotating cylinder 21, thereby realizing the transmission connection between the first driving structure 30 and the rotating cylinder 21.

[0137] In some embodiments, the first engaging member 522 includes a first hook, and the second engaging member 212 includes a second hook.

[0138] In the above embodiment, the first engaging member 522 and the second engaging member 212 are both in the form of hook structures, which have good engaging effects and are not easy to be unhooked.

[0139] Of course, in other alternative implementations, the first engaging member 522 and the second engaging member 212 may also adopt structural forms such as claws, platforms, slots, etc., which are not limited in this embodiment.

[0140] In some embodiments, the support body 521 is an annular structure, there are multiple first hooks, and the multiple first hooks are arranged at intervals along the circumference of the support body 521, and there are also multiple second hooks correspondingly.

[0141] In the above embodiment, through the cooperation of the above-mentioned multiple first hooks and second hooks, the clutch structure 50 is more stable in cooperation with the rotating cylinder 21 when in the braking state, forming a uniform, stable and reliable limiting connection in the circumferential direction, which is not easy to fall off and separate, and has a better locking effect.

[0142] Specifically, the limiting portion 51 is a hollow cylindrical structure, the supporting body 521 is an annular plate structure, the supporting body 521 is fixedly arranged at one end of the limiting portion 51 away from the first driving structure 30, and the first hooks are evenly spaced along the circumference of the supporting body 521. Preferably, the limiting portion 51, the supporting body 521, and the first hooks are integrally formed.

[0143] In some embodiments, a first slot into which the second hook can be inserted is formed between two adjacent first hooks, and a second slot into which the first hook can be inserted is formed between two adjacent second hooks; the first hook and the second hook respectively include a hook body 5221, a bent hook portion 5222 and an avoidance portion 5223, a bent hook portion 5222 is fixedly provided on one side of the end of the hook body 5221, and the avoidance portion 5223 is formed by cutting an angle on the other side; the avoidance portion 5223 is used to avoid the movement of the first hook and the second hook when the clutch structure 50 rotates along the unlocking direction, so as to facilitate the first hook to escape from the second slot and the second hook to escape from the first slot.

[0144] In the above embodiment, the first hook and the second hook can form a good engagement effect when the clutch structure 50 and the rotating cylinder 21 are locked through the respectively arranged bent hook portions 5222, and can be more easily disengaged when the clutch structure 50 and the rotating cylinder 21 are unlocked through the respectively arranged avoidance portions 5223 to avoid getting stuck.

[0145] Specifically, the curved hook portion 5222 of the first hook and the curved hook portion 5222 of the second hook are oriented in opposite directions, and the curved hook portion 5222 and the avoidance portion 5223 are arranged on both sides of the hook body 5221, so as to achieve the effect that the first hook and the second hook are engaged with each other during forward rotation, and the first hook and the second hook are separated during reverse rotation.

[0146] In some embodiments, the first engaging member 522 is fixedly disposed on a side wall of the supporting body 521 close to the first driving structure 30 .

[0147] In the above embodiment, by fixing the first engaging member 522 on a side wall of the supporting body 521 close to the first driving structure 30, it is more convenient to cooperate with the second engaging member 212, while also avoiding affecting the subsequent cooperation between the clutch structure 50 and the transmission member 12 and the second driving structure 40.

[0148] Specifically, the directions of the hook portions 5222 of multiple first engaging members 522 are consistent, the first engaging members 522 and the limiting portion 51 are located above the supporting body 521, the directions of the hook portions 5222 of multiple second engaging members 212 are consistent, and the directions of the hook portions 5222 of the first engaging member 522 and the hook portions 5222 of the first engaging member 522 are opposite.

[0149] In some embodiments, the rotating cylinder 21 includes an inner cylinder 21a. Along the axial direction of the mop rod 100, the inner cylinder 21a includes a first cylinder 21a1 and a second cylinder 21a2 arranged in sequence from a direction away from the mop head 200 to a direction close to the mop head 200; the first cylinder 21a1 is suitable for engaging or disengaging with the first driving structure 30, and a spiral guide groove 210 is arranged in the second cylinder 21a2.

[0150] In the above embodiment, the inner cylinder 21a adopts the design of the first cylinder 21a1 and the second cylinder 21a2, which is more convenient for assembly and also facilitates the arrangement of the second meshing teeth 211, the second engaging member 212, the spiral guide groove 210 and other structures.

[0151] In some embodiments, the rotating cylinder 21 further includes an outer cylinder 21 b , which is sleeved outside the inner cylinder 21 a , and the first cylinder body 21 a 1 and the second cylinder body 21 a 2 are fixedly connected to the outer cylinder 21 b , respectively.

[0152] In the above embodiment, the rotating cylinder 21 adopts the design of an inner cylinder 21a and an outer cylinder 21b, and the first cylinder 21a1 and the second cylinder 21a2 are fixedly connected to the outer cylinder 21b respectively, thereby realizing the fixation of the first cylinder 21a1 and the second cylinder 21a2 and the outer cylinder 21b, and the three rotate together. The outer cylinder 21b is set to connect and fix the first cylinder 21a1 and the second cylinder 21a2, and can also be covered outside the first cylinder 21a1 and the second cylinder 21a2, thereby improving the aesthetics of the overall structure.

[0153] Specifically, the first barrel 21a1 is disposed above the second barrel 21a2, the second barrel 21a2 is located at one end close to the mop head 200, the lower end of the first barrel 21a1 is connected to the upper end of the second barrel 21a2, and the first barrel 21a1 and the second barrel 21a2 can be fixed to the outer barrel 21b by a connecting piece, or can be fixed to the outer barrel 21b by bonding. Of course, in other alternative embodiments, the first barrel 21a1 and the second barrel 21a2 can also be directly fixed or adopt an integrated structural design, which is not limited in this embodiment.

[0154] Furthermore, in this embodiment, the lower rod assembly 20 includes an outer cylinder 21b, a first cylinder body 21a1 and a second cylinder body 21a2 fixed in one body, that is, a rotating cylinder 21. The mop rod 100 also includes an outer cover cylinder 15, and the upper rod assembly 10 also includes an operating rod 14, which is rotatably arranged above the outer cover cylinder 15, and the outer cover cylinder 15 is located between the operating rod 14 and the rotating cylinder 21. The upper end of the spiral rod 11 is fixed in the operating rod 14 through a connector, and a handle is also provided at the upper end of the operating rod 14 for easy gripping. The user can control the movement of the spiral rod 11 by operating the handle or the operating rod 14, and the lower end of the spiral rod 11 passes through the outer cover cylinder 15 and extends into the rotating cylinder 21.

[0155] Furthermore, the upper end of the lower rod assembly 20 extends into the outer cover tube 15. Specifically, the outer diameter of the rotating cylinder 21 is smaller than the inner diameter of the outer cover tube 15, and the rotating cylinder 21 can rotate relative to the outer cover tube 15. Furthermore, the upper end of the first cylinder 21a1 is located in the outer cover tube 15, and a lubricating sleeve is also sleeved on the outer periphery of the first cylinder 21a1. The lubricating sleeve is sleeved on the upper end of the first cylinder 21a1, and the lubricating sleeve is used to reduce the friction resistance between the rotating cylinder 21 and the outer cover tube 15 when the rotating cylinder 21 rotates.

[0156] Furthermore, a sealing piece is provided at the upper end of the first cylinder 21a1, which is clamped and fixed in the upper end port of the first cylinder 21a1 to prevent other components such as the first driving structure 30 in the rotating cylinder 21 from escaping from the upper end port of the first cylinder 21a1. An opening is provided in the center of the sealing piece for the spiral rod 11 to extend into.

[0157] In this embodiment, the operating rod 14 is fixedly connected to the spiral rod 11, and the operating rod 14 is sleeved outside the outer cover tube 15, and can drive the spiral rod 11 to move up and down along the hollow area inside the outer cover tube 15. The outer cover tube 15 is sleeved on the upper end of the rotating cylinder 21, and the rotating cylinder 21 is rotatably connected to the outer cover tube 15, and is connected to the spiral rod 11 through the first driving structure 30 in the middle of the mop rod 100. The first driving structure 30 is provided with a spiral groove matching the spiral rod 11 inside, so as to rotate relatively on the spiral rod 11. When the spiral rod 11 moves up and down in the hollow area inside the outer cover tube 15, the second cylinder 21a2 can drive the mop plate to rotate.

[0158] In some embodiments, the rotating cylinder 21 is provided with a second meshing tooth 211 for transmission connection with the first driving structure 30, and the second meshing tooth 211 is arranged on the inner periphery of one end of the first cylinder 21a1 close to the second cylinder 21a2.

[0159] In the above embodiment, by setting the second meshing tooth 211 on the inner periphery of the first cylinder 21a1, no additional axial space of the first cylinder 21a1 is occupied, and it is more convenient to cooperate with the first meshing tooth 31. The second meshing tooth 211 is set at one end close to the second cylinder 21a2, that is, at the lower end of the first cylinder 21a1, so that when the upper rod assembly 10 is pressed down to drive the first driving structure 30 to move downward, it can engage with the second meshing tooth 211 at the lower end of the first cylinder 21a1.

[0160] Optionally, the second meshing teeth 211 are integrally formed on the inner circumferential wall of the first cylinder 21a1 by injection molding, cutting or other processes.

[0161] In some embodiments, a first engaging member 522 is provided on the clutch structure 50 of the rotary mop, and a second engaging member 212 is provided on the rotating cylinder 21 corresponding to the first engaging member 522, and the second engaging member 212 is fixedly provided on the first cylinder 21a1 and is located on one side end wall of the first cylinder 21a1 close to the second cylinder 21a2.

[0162] In the above embodiment, by arranging the second engaging member 212 on the end of the first cylinder 21a1 close to the second cylinder 21a2, it is convenient for the second engaging member 212 to engage with the first engaging member 522 when the clutch structure 50 is in the braking state.

[0163] Specifically, the first cylinder 21a1 includes a main body section and a reduced diameter section arranged at the lower end of the main body section, and an annular stepped space is formed between the lower end wall of the main body section and the outer peripheral wall of the reduced diameter section. The second engaging member 212 is fixedly arranged between the main body section and the reduced diameter section. Specifically, the upper end of the second engaging member 212 is fixedly arranged on the lower end wall of the main body section, and the inner side wall surface of the second engaging member 212 is fixed on the outer peripheral wall of the reduced diameter section. Compared with directly fixing the second engaging member 212 on the lower end wall of the main body section, the structural strength of the second engaging member 212 is higher, so that the second engaging member 212 has higher stability when engaging with the first engaging member 522.

[0164] In some embodiments, the upper rod assembly 10 further includes a transmission member 12, which is fixedly arranged at one end of the spiral rod 11 extending into the rotating cylinder 21, and the transmission member 12 includes a transmission portion 121 and a rod body portion 122, and the rod body portion 122 is fixedly arranged on a side of the transmission portion 121 close to the mop head 200; the second driving structure 40 is movably sleeved on the rod body portion 122, and the second driving structure 40 is limited on the rod body portion 122 in the axial direction of the mop rod 100; when the spiral rod 11 moves along the axial direction of the mop rod 100 toward the mop head 200, the transmission portion 121 abuts against the second driving structure 40, and can drive the second driving structure 40 to move along the axial direction of the mop rod 100, so that the guide portion 41 provided on the second driving structure 40 can slide in the spiral guide groove 210 in the rotating cylinder 21 to drive the rotating cylinder 21 to rotate.

[0165] In the above embodiment, by providing the transmission member 12 on the end of the spiral rod 11 and movably sleeved the second driving structure 40 on the rod body 122, when the spiral rod 11 moves along the axial direction of the mop rod 100 toward the mop head 200, the transmission portion 121 can abut against the second driving structure 40, thereby clamping the second driving structure 40 and driving the second driving structure 40 to move downward, so that the guide portion 41 provided on the second driving structure 40 can slide in the spiral guide groove 210 in the rotating cylinder 21, thereby driving the rotating cylinder 21 to rotate.

[0166] Optionally, the transmission member 12 is fixed to the spiral rod 11 by a pin. A limiting structure 13 is provided on the end of the rod body 122 , and the limiting structure 13 is used to limit the second driving structure 40 to prevent the second driving structure 40 from coming off the transmission member 12 .

[0167] In this embodiment, the transmission member 12 and the second driving structure 40 are located in the second cylinder 21a2. When the transmission member 12 pushes the second driving structure 40 to move downward, the second cylinder 21a2 can rotate at a low speed and save effort through the cooperation of the guide part 41 on the second driving structure 40 and the spiral guide groove 210 in the second cylinder 21a2.

[0168] In some embodiments, a first limiting tooth 1211 is provided at one end of the transmission part 121 close to the second driving structure 40, and a first matching groove 42 is provided on the second driving structure 40 corresponding to the first limiting tooth 1211; when the spiral rod 11 moves along the axial direction of the mop rod 100 toward the direction close to the mop head 200, the first limiting tooth 1211 extends into the first matching groove 42, so that the transmission member 12 and the second driving structure 40 form a limit in the circumferential direction of the mop rod 100.

[0169] In the above embodiment, through the design of the first limiting tooth 1211 and the first matching groove 42, the transmission member 12 can not only axially push the second driving structure 40 to move in the axial direction of the mop rod 100, but also when the spiral rod 11 drives the transmission member 12 to move down to the extreme position, the transmission member 12 and the second driving structure 40 are locked in the circumferential direction.

[0170] Specifically, the transmission part 121 has a block-shaped body, the outer circumferential cross-section of the block-shaped body is circular, a slot is provided in the transmission part 121 for the end of the spiral rod 11 to extend into, and pin holes are provided on the transmission part 121 and the ends of the spiral rod 11, respectively, and the pins pass through the pin holes on the transmission part 121 and the spiral rod 11 in sequence to achieve a fixed connection between the transmission member 12 and the spiral rod 11. A first limiting tooth 1211 is fixedly provided at the lower end of the transmission part 121, and preferably, there are a plurality of first limiting teeth 1211, and the plurality of first limiting teeth 1211 are arranged at intervals along the circumference of the transmission part 121.

[0171] In some embodiments, the first limiting tooth 1211 and the first matching groove 42 are matched through straight surfaces on one side of the circumferential direction of the mop rod 100 and matched through inclined surfaces on the other side.

[0172] In the above embodiment, the first limiting tooth 1211 and the first matching groove 42 adopt a method of matching with a straight surface on one side and a bevel surface on the other side, so that the second cylinder 21a2 can in turn drive the second drive structure 40 to rotate around the spiral rod 11 when rotating. Since the second drive structure 40 and the transmission member 12 are slipped by the bevel guide, the transmission member 12 can effectively avoid the second drive structure 40 from being stuck, thereby also avoiding the second cylinder 21a2 from being stuck.

[0173] In this embodiment, the working principle of the rotary mop is as follows:

[0174] When the second engaging member 212 of the first barrel 21a1 is engaged with the first engaging member 522 on the clutch structure 50, the spiral rod 11 moves up and down in the hollow area of ​​the outer cover tube 15, and the transmission member 12 moves up and down following the spiral rod 11. The transmission member 12 abuts against the second driving structure 40 and drives the second driving structure 40 to move up and down. When the second driving structure 40 moves up and down, the guide portion 41 provided thereon slides in the spiral guide groove 210 inside the second barrel 21a2, thereby driving the second barrel 21a2 to rotate, and the second barrel 21a2 can drive the mop head 200 to rotate. Since the first barrel 21a1 is fixedly connected to the second barrel 21a2, the second barrel 21a2 drives the first barrel 21a1 to rotate, and the first barrel 21a1 can drive the clutch structure 50 to rotate. When the transmission member 12 is in contact with the second drive structure 40, the transmission member 12 can drive the second drive structure 40 to move downward with it when it moves downward. When the transmission member 12 stops moving downward, the inertia of the mop's rotation causes the second drive structure 40 to continue rotating. Since the transmission member 12 and one side of the second drive structure 40 are matched through an inclined surface, the second drive structure 40 will automatically disengage from the transmission member 12 to achieve separation.

[0175] When the second engaging member 212 on the first barrel 21a1 is disengaged from the first engaging member 522 on the clutch structure 50, the operating rod 14 is lifted upward, and the second meshing teeth 211 of the first barrel 21a1 are engaged with the first meshing teeth 31 on the first drive structure 30. At this time, the user presses the operating rod 14 again, and the screw rod 11 can move downward, driving the first drive structure 30 to rotate, and the first drive structure 30 rotates to drive the first barrel 21a1 to rotate, and the first barrel 21a1 is fixedly connected to the second barrel 21a2, so that the first barrel 21a1 can drive the second barrel 21a2 to rotate. When the second barrel 21a2 rotates, it in turn drives the second drive structure 40 to rotate around the screw rod 11. Since the second drive structure 40 and the transmission member 12 can slip through the inclined surface, the transmission member 12 is prevented from being stuck in the second drive structure 40, and the second barrel 21a2 is also prevented from being stuck. The above process realizes the function of rotating the mop head 200 through the spiral guide groove 210 of the second cylinder 21a2 and the spiral rod 11. In actual application, different spiral angles are set for the spiral rod 11 and the spiral guide groove 210 to achieve speed difference when the mop plate rotates.

[0176] In some embodiments, the upper rod assembly 10 further includes a limiting structure 13 , which is fixedly disposed on the rod body 122 and is used to limit the second driving structure 40 to prevent the second driving structure 40 from being separated from the transmission member 12 .

[0177] In the above embodiment, the limiting structure 13 provided on the rod body 122 can effectively prevent the second driving structure 40 from being separated from the transmission member 12 , so that the second driving structure 40 and the spiral rod 11 can achieve stable transmission cooperation through the transmission member 12 .

[0178] In some embodiments, an elastic deformation portion 1221 is provided at the end of the rod body 122, and the limiting structure 13 is a limiting ring; when the limiting ring is inserted into the elastic deformation portion 1221, the elastic deformation portion 1221 is closed to facilitate the limiting ring to pass through the elastic deformation portion 1221 and be sleeved on the rod body 122; when the limiting ring passes through the elastic deformation portion 1221, the elastic deformation portion 1221 opens to prevent the limiting ring from detaching from the rod body 122.

[0179] In the above embodiment, the elastic deformation portion 1221 is provided at the end of the rod body 122, which can shrink inward when squeezed by the limiting ring, thereby facilitating the assembly of the limiting ring onto the rod body 122. When the limiting ring is assembled onto the rod body 122, the elastic deformation portion 1221 can expand outward and restore deformation under the action of its own elastic force, thereby limiting the limiting ring on the rod body 122 and preventing the limiting ring from detaching from the rod body 122. The provision of the elastic deformation portion 1221 not only facilitates the assembly of the limiting ring, but also effectively prevents the limiting ring from detaching from the rod body 122.

[0180] Optionally, the elastic deformation part 1221 is integrally formed and arranged on the end of the rod body 122. The elastic deformation part 1221 is a buckle structure with a crack in the middle, and the buckle structure includes a buckle body and a tapered guide part arranged at the lower end of the buckle body. The outer diameter of the buckle body is larger than the outer diameter of the rod body 122. The tapered guide part is arranged to facilitate the assembly of the limit ring, and the elastic deformation part 1221 is more easily deformed by the arranged crack.

[0181] In this embodiment, the screw rod 11, the transmission member 12, and the limiting structure 13 are assembled as one body, their relative positions remain unchanged, and the three move synchronously.

[0182] In some embodiments, the transmission member 12 is located between the clutch structure 50 and the second driving structure 40 of the rotary mop; a second limiting tooth 1212 is provided at one end of the transmission part 121 close to the clutch structure 50, and a second matching groove 523 is provided on the clutch structure 50 corresponding to the second limiting tooth 1212; the second limiting tooth 1212 extends into the second matching groove 523, so that the transmission member 12 and the clutch structure 50 form a limit in the circumferential direction of the mop rod 100.

[0183] In the above embodiment, through the design of the second limiting tooth 1212 and the second matching groove 523, the transmission member 12 and the clutch structure 50 are limited in the circumferential direction, so that the two can rotate synchronously.

[0184] Specifically, the second limiting teeth 1212 and the second matching grooves 523 are respectively arranged in a plurality of intervals along the circumferential direction, and the plurality of second limiting teeth 1212 and the plurality of second matching grooves 523 are matched one by one. The clutch structure 50 is sleeved on the twisted rod, can move up and down, and can also rotate slightly, but when the second limiting teeth 1212 of the transmission member 12 are inserted into the second limiting groove at the lower end of the clutch structure 50, the clutch structure 50 cannot rotate. The upper end surface of the limiting portion 51 of the clutch structure 50 is a plane, and the lower end surface of the first driving structure 30 is also a plane. When the first hook of the clutch structure 50 is locked with the second hook of the first cylinder 21a1, and the limiting portion 51 thereof abuts against the first driving structure 30, the first driving structure 30 cannot continue to move downward, and thus cannot mesh with the meshing teeth on the first cylinder 21a1. At this time, only the second driving structure 40 drives the rotating cylinder 21 to rotate.

[0185] In some embodiments, the guide portion 41 includes a protrusion structure fixedly disposed on the outer peripheral wall of the second driving structure 40 .

[0186] In the above embodiment, the guide portion 41 adopts a protruding structure, which has a simple structure and is convenient for processing and forming.

[0187] Optionally, the guide portion 41 is a strip-shaped protrusion whose curvature matches the curvature of the spiral guide groove 210. By adopting the structural form of the strip-shaped protrusion, the contact area between the guide portion 41 and the spiral guide groove 210 is larger, and the transmission effect is better.

[0188] Preferably, two groups of spiral guide grooves 210 are symmetrically arranged in the second cylinder 21a2, and two groups of strip protrusions are also symmetrically arranged on the outer wall of the second driving structure 40. The two groups of strip protrusions match the two groups of spiral guide grooves 210 in a one-to-one correspondence. Through the cooperation of the two groups of strip protrusions and the spiral guide grooves 210, the driving force provided by the second driving structure 40 when driving the rotating cylinder 21 to rotate is more balanced and stable.

[0189] The high and low speed switching process of the rotary mop provided in this embodiment is as follows:

[0190] In this embodiment, the clutch structure 50 is equivalent to a switch for switching high-speed rotation and low-speed rotation. The high-speed and low-speed switching operation is to pull the upper rod assembly 10 and the lower rod assembly 20 apart, and rotate the upper rod assembly 10 and / or the lower rod assembly 20, so that the clutch structure 50 and the first cylinder 21a1 can be engaged or disengaged to achieve high-speed and low-speed switching. The first drive structure 30 is sleeved outside the spiral rod 11. The first drive structure 30 can slide up and down along the spiral rod 11 and rotate at the same time. The spiral rod 11 is fixed with the handle and the operating rod 14 and moves up and down. The first drive structure 30 is provided with a spiral groove that cooperates with the spiral rod 11.

[0191] Specifically, when the first engaging member 522 on the clutch structure 50 is engaged with the second engaging member 212 on the first cylinder 21a1, the axial position of the clutch structure 50 in the mop rod 100 is locked, and the limiting portion 51 of the clutch structure 50 extends into the first cylinder 21a1, and the extending length of the limiting portion 51 is greater than the length of the second meshing tooth 211, pressing the upper rod assembly 10 downward, and when the first driving structure 30 moves downward to a position abutting against the limiting portion 51 of the clutch structure 50, the first driving structure 30 cannot continue to move downward, so that the first meshing tooth 31 on the first driving structure 30 and the second meshing tooth 211 on the first cylinder 21a1 cannot engage with each other, and the two are separated. When the spiral rod 11 moves downward, it will drive the transmission member 12 thereon to move downward, abut against the second driving structure 40 and push the second driving structure 40 to move. The force is transmitted to the second cylinder 21a2 through the guide part 41 and the spiral guide groove 210 of the second driving structure 40, so that the second cylinder 21a2 drives the entire rotating cylinder 21 to rotate at a low speed.

[0192] Furthermore, when the first engaging member 522 on the clutch structure 50 is disengaged from the second engaging member 212 on the first cylinder 21a1, the upper rod assembly 10 is pressed downward, and the first driving structure 30 can move downward to the position where the first meshing tooth 31 meshes with the second meshing tooth 211 on the first cylinder 21a1. The lower end of the first driving structure 30 is supported by the second meshing tooth 211, and under the action of the spiral groove that cooperates between the spiral rod 11 and the first driving structure 30, the first driving structure 30 can be driven to rotate. Since the first driving structure 30 and the first cylinder 21a1 are meshed, the driving force of the spiral rod 11 can be transmitted to the first cylinder 21a1 through the first driving structure 30, thereby driving the entire rotating cylinder 21 to rotate at high speed.

[0193] In simple terms, the clutch structure 50 is hooked with the first cylinder 21a1, the first drive structure 30 is separated from the first cylinder 21a1, and only the second drive structure 40 slides in the spiral guide groove 210 of the second cylinder 21a2 at a low speed; the clutch structure 50 is disengaged from the first cylinder 21a1, and the first drive structure 30 is pressed downward against the second meshing tooth 211 on the first cylinder 21a1, and meshes with the second meshing tooth 211 at a high speed. When rotating at a high speed, the first drive structure 30 rotates fast, and the second drive structure 40 rotates slowly. Under the action of inertia and the action of the first limit tooth 1211 and the inclined surface of the first matching groove 42, the second drive structure 40 will be disengaged from the transmission member 12, so that only the first drive structure 30 plays the role of driving the rotating cylinder 21 to rotate. Since the spiral angle of the spiral rod 11 is smaller than the spiral angle of the spiral guide groove 210, the rotating cylinder 21 rotates at a higher speed when the first drive structure 30 drives it.

[0194] When switching, pull the upper rod assembly 10 and the lower rod assembly 20 to the maximum position, and then rotate the upper rod assembly 10 and the lower rod assembly 20. When high-speed dehydration is required, first disengage the first cylinder 21a1 and the clutch structure 50 from the hook, and then press down the spiral rod 11. The first drive structure 30 moves downward to a position engaged with the first cylinder 21a1, and the rotating cylinder 21 can rotate under the drive of the first drive structure 30; when low-speed washing is required, first rotate the upper rod assembly 10 and the lower rod assembly 20 so that the first cylinder 21a1 and the clutch structure 50 are engaged, and then press down the spiral rod 11. The first drive structure 30 cannot move downward under the abutment and limiting action of the limiting portion 51 of the clutch structure 50, and can only idle and cannot engage with the first cylinder 21a1. As a result, the first drive structure 30 does not work, and the rotating cylinder 21 only rotates under the drive of the second drive structure 40.

[0195] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
