Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning devices, in particular to a mopping module and a cleaning device. BACKGROUND

[0002] At present, there are various styles of integrated mop and vacuum cleaners, electric mops and the like on the market. Most of these integrated mop and vacuum cleaners have a water tank with a mop outside the rear of the floor brush. The water tank realizes water supply to the mop through automatic water seepage or mechanical pump water spraying.

[0003] Through the automatic water seepage mode, many products do not control the water quantity well. Either the water seepage is too slow or too fast. Some products of some brands cannot discharge water after closing the cover of the water inlet, which provides a poor user experience. Through the mechanical pump water spraying mode, the water quantity can be well controlled, but the mechanical pump needs to be stepped to pump water during mopping. Generally, the mechanical pump needs to be stepped to pump water after mopping 1-1.5 square floor, which is very troublesome. In addition, the mop is not evenly wet during mopping. The mop is relatively wet after pumping water, and gradually becomes dry. The user experience is not good. Therefore, the water tank in the related art cannot uniformly supply water to the mop, which affects the mopping effect. SUMMARY

[0004] Therefore, it is necessary to provide a mopping module and a cleaning device to solve the problem that the water tank cannot uniformly supply water to the mop.

[0005] A mopping module, comprising:

[0006] a water tank, the water tank being internally formed with a receiving cavity; and

[0007] an air inlet member, the air inlet member being formed with an air inlet channel, and the air inlet member being telescopically arranged on the water tank;

[0008] The air inlet member has an air inlet position and an air cut-off position on the telescopic path thereof. When the air inlet member is at the air inlet position, the air inlet channel is in communication with the receiving cavity and the outside. When the air inlet member is at the air cut-off position, the air inlet channel is disconnected from the outside.

[0009] The above-mentioned mopping module is used in a cleaning device. When mopping is needed, a user can move the air inlet member in the mopping module to the air inlet position, so that the accommodating cavity inside the water tank is in communication with the outside through the air inlet passage on the air inlet member. During the process of water outlet of the water tank, the outside air can continuously enter the accommodating cavity, so as to keep the air pressure balance inside and outside the water tank, and the cleaning liquid in the water tank can be evenly and orderly seeped out to supply water to the mop at the bottom, so as to prevent the water supply process from being interrupted due to too small air pressure inside the water tank, and improve the water outlet uniformity of the water tank. When the mopping is completed or the mopping is not needed, the user can move the air inlet member to the air cut-off position, so that the air inlet passage of the air inlet member is blocked, and the outside air is blocked outside the water tank and cannot enter the accommodating cavity in the water tank. The cleaning liquid in the water tank cannot seep out under the pressure of the outside atmosphere, so as to close the water seepage function and prevent the mopping module from leaking when the mopping is not needed.

[0010] In one of the embodiments, the air inlet member is provided with an air passage opening in communication with the air inlet passage;

[0011] When the air inlet member is located at the air inlet position, the air passage opening is at least partially exposed outside the water tank; and when the air inlet member is located at the air cut-off position, the air passage opening is completely hidden in the accommodating cavity.

[0012] In one of the embodiments, the air passage opening is extended along a direction axially parallel to the air inlet passage, and the air inlet member reciprocally moves along the axial direction of the air inlet passage between the air inlet position and the air cut-off position.

[0013] In one of the embodiments, the air inlet member comprises an operation part and an air inlet pipe provided with the air inlet passage and the air passage opening. One end of the air inlet pipe is telescopically arranged in the accommodating cavity along the axial direction of the air inlet pipe, and the other end of the air inlet pipe extends out of the accommodating cavity and is connected with the operation part.

[0014] In one of the embodiments, the air inlet member further comprises a limiting part which is protrudingly arranged on the outer periphery of the air inlet pipe and located in the accommodating cavity.

[0015] The limiting part is located at one end of the air passage opening away from the operation part, and the limiting part is provided with an air outlet opening in communication with the air inlet passage and the accommodating cavity.

[0016] In one of the embodiments, a guide member is protrudingly arranged on the bottom wall of the water tank and located in the accommodating cavity, and the air inlet member is telescopically sleeved on the guide member along the axial direction of the air inlet passage.

[0017] In one embodiment, the mopping module further includes a fixing plate fixedly disposed on the water tank. The fixing plate and the water tank are respectively provided with a first mounting hole and a second mounting hole. The air intake component is retractably disposed on the water tank through the first mounting hole and the second mounting hole.

[0018] When the air intake component is in the air intake position, the first mounting hole connects to the outside and the air outlet; when the air intake component is in the air cut-off position, the first mounting hole is disconnected from the air outlet.

[0019] In one embodiment, the fixing plate includes a plate body and a protruding ring, the plate body is fixedly installed on the water tank, and the protruding ring is disposed on the side of the plate body facing away from the water tank;

[0020] The first mounting hole includes a main hole that passes through the convex ring and the plate, and an air inlet that is opened on the outer periphery of the convex ring and communicates with the main hole; the air inlet extends through the main hole into the second mounting hole and the accommodating cavity, and the air outlet is aligned with or offset from the air inlet as the air inlet extends and retracts.

[0021] In one embodiment, the mopping module further includes a seal that is interference-fitted around the air inlet and abuts against the fixing plate and the water tank.

[0022] In one embodiment, the water outlet component and the mopping component are further included. The bottom wall of the water tank has a water outlet that communicates with the accommodating cavity. The water outlet component is assembled at the water outlet. The mopping component is covered outside the bottom wall of the water tank. The water outlet component is used to leak water into the mopping component.

[0023] A cleaning device includes the aforementioned mopping module. Attached Figure Description

[0037] Referring to Figure 1 In an embodiment of the present application, a mop module 100 is provided for assembling in a cleaning device to perform wet wiping on a surface to be cleaned.

[0038] Referring to Figure 2 , Figures 5-6 The mop module 100 includes a water tank 10 and an air inlet member 30. The water tank 10 has an accommodation cavity 11 formed therein, and the air inlet member 30 has an air inlet passage formed thereon and is telescopically arranged on the water tank 10. The air inlet member 30 has an air inlet position and an air cut-off position on the telescopic path thereof. When the air inlet member 30 is in the air inlet position, the air inlet passage is in communication with the accommodation cavity 11 and the outside to allow outside air to enter the inside of the water tank 10, thereby achieving air pressure balance inside and outside the water tank 10 and preventing the water tank 10 from being unable to discharge water due to too small internal air pressure. When the air inlet member 30 is in the air cut-off position, the air inlet passage is disconnected from the outside, thereby stopping the water tank 10 from discharging water.

[0039] When the user needs to mop, the user can move the air inlet piece 30 to the air inlet position, so that the accommodating cavity 11 inside the water tank 10 is in communication with the outside through the air inlet passage on the air inlet piece 30. During the process of water outlet of the water tank 10, the outside air can continuously enter the accommodating cavity 11, so as to keep the air pressure balance between the inside and outside of the water tank 10, and the cleaning liquid in the water tank 10 can be uniformly and orderly seeped out to supply water to the mop at the bottom, so as to prevent the water supply process from being interrupted due to too small air pressure in the water tank 10, and improve the water outlet uniformity of the water tank 10. When the mopping is completed or the mopping is not needed, the user can move the air inlet piece 30 to the air cut-off position, so that the air inlet passage of the air inlet piece 30 is blocked, the outside air is blocked outside the water tank 10, and cannot enter the accommodating cavity 11 of the water tank 10. The cleaning liquid in the water tank 10 cannot seep out under the pressure of the outside atmosphere, so as to close the water seepage function and prevent the mop module 100 from leaking when the mopping is not performed.

[0040] In some embodiments, the mop module 100 further comprises a water outlet assembly 42 and a mop piece 44. The bottom wall of the water tank 10 is provided with a water outlet opening in communication with the accommodating cavity 11. The water outlet assembly 42 is assembled at the water outlet opening. The mop cloth is wrapped outside the bottom wall of the water tank 10. The water outlet assembly 42 is used for seeping water to the mop piece 44. When the air inlet piece 30 is in the air inlet position, the air pressure in the water tank 10 is balanced. The cleaning liquid in the water tank 10 can seep out through the water outlet assembly 42 and flow to the mop piece 44, so that the mop piece 44 can be wetted and the mopping work can be performed.

[0041] Specifically, the water outlet assembly 42 comprises a support and a cotton core. The support is assembled at the water outlet opening and extends into the accommodating cavity 11. The cotton core is sleeved in the support and is in fluid communication with the cleaning liquid in the accommodating cavity 11, so as to seep out the cleaning liquid in the water tank 10 to the mop piece 44 when the air pressure in the water tank 10 is balanced. Optionally, the mop piece 44 is a mop cloth. The mop piece 44 is attracted and clamped on the bottom wall of the water tank 10 through the cooperation of the magnetic assembly.

[0042] Referring to Figures 3-6 In some embodiments, the air inlet piece 30 is provided with an air inlet opening 514 in communication with the air inlet passage. When the air inlet piece 30 is in the air inlet position, the air inlet opening 514 is at least partially exposed outside the water tank 10, so as to communicate with the outside, allow the outside air to enter the air inlet passage through the air inlet opening 514 and flow into the accommodating cavity 11, achieve the air pressure balance between the inside and outside of the water tank 10, and allow the cleaning liquid in the water tank 10 to be uniformly and orderly seeped out to supply water to the mop cloth. When the air inlet piece 30 is in the air cut-off position, the air passage opening 33 is completely hidden in the accommodating cavity 11, so that the air passage opening 33 is no longer exposed outside the water tank 10, the outside air cannot enter the air passage opening 33, and the communication between the air inlet passage and the outside is blocked.

[0043] Further, the air passage 33 is arranged in a direction parallel to the axial direction of the air inlet channel, and the air inlet member 30 is arranged to reciprocate along the axial direction of the air inlet channel between the air inlet position and the air cut-off position. That is, the air inlet member 30 is arranged to reciprocate along the axial direction of the air inlet channel, the air inlet position and the air cut-off position are arranged along the axial direction of the air inlet channel, and the air passage 33 is arranged to reciprocate along the axial direction of the air inlet channel. When the air inlet member 30 reciprocates along the axial direction of the air inlet channel, the air passage 33 also reciprocates relative to the water tank 10, so that the air passage 33 can be moved in and out of the water tank 10 to control the opening and closing of the water seepage function.

[0044] In some embodiments, the air inlet member 30 comprises an operation portion 32 and an air inlet pipe 34 having an air inlet channel and an air passage 33. That is, the air inlet pipe 34 has an air inlet channel formed therein, and the air passage 33 is arranged on the air inlet pipe 34 to communicate with the air inlet channel. One end of the air inlet pipe 34 is arranged to reciprocate along the axial direction of the air inlet pipe 34 in the accommodating cavity 11, and the other end of the air inlet pipe 34 extends out of the accommodating cavity 11 and is connected to the operation portion 32. The operation portion 32 is arranged outside the water tank 10 and connected to the air inlet pipe 34, so that the user can easily pull or press the air inlet member 30. By applying an external force to the operation portion 32, the air inlet pipe 34 is driven to move along the axial direction of the air inlet pipe 34, so that the air passage 33 on the air inlet pipe 34 extends out of or into the water tank 10, thereby switching the air inlet channel between the open and closed states.

[0045] Further, the air inlet member 30 further comprises a limiting portion 35 arranged on the outer periphery of the air inlet pipe 34 and located in the accommodating cavity 11. The limiting portion 35 is arranged at the end of the air passage 33 away from the operation portion 32, and the limiting portion 35 has an air outlet 351 arranged thereon to communicate with the air inlet channel and the accommodating cavity 11. That is, the limiting portion 35 is arranged at the bottom of the air inlet pipe 34, and when the air inlet pipe 34 reciprocates along the axial direction of the air inlet pipe 34, the limiting portion 35 moves along with the air inlet pipe 34 towards or away from the top wall of the water tank 10. When the air inlet pipe 34 moves upwards and the air passage 33 is completely located outside the water tank 10, the limiting portion 35 at the bottom end of the air passage 33 is arranged to protrude relative to the air inlet pipe 34, so as to abut against the top wall of the water tank 10, thereby preventing the air inlet pipe 34 from being pulled out of the water tank 10, limiting the upward movement of the air inlet pipe 34, and facilitating the operation of the air inlet member 30.

[0046] Further, the limiting portion 35 has an air outlet 351 arranged thereon to communicate with the air inlet channel, so that the external air entering the air inlet channel through the air passage 33 can flow into the accommodating cavity 11 through the air outlet 351 of the limiting portion 35, and the limiting portion 35 does not affect the air flow communication between the air inlet member 30 and the accommodating cavity 11.

[0047] In some embodiments, the bottom wall of the water tank 10 is provided with a guide 13 located in the accommodating cavity 11, and the air inlet member 30 is telescopically sleeved on the guide 13 along the axial direction of the air inlet channel. Thus, the guide 13 serves as a support point for the air inlet member 30 during movement, so that the telescopic movement of the air inlet member 30 is more stable. Specifically, the guide 13 extends along the axial direction of the air inlet channel to guide the air inlet member 30 to move telescopically along the axial direction of the air inlet member 30.

[0048] Referring to Figure 2 and Figures 4-5 In some embodiments, the mop module 100 further comprises a fixed plate 50 fixedly arranged on the water tank 10. The fixed plate 50 and the water tank 10 are respectively provided with a first mounting hole 51 and a second mounting hole 15. The air inlet member 30 is telescopically arranged on the water tank 10 through the first mounting hole 51 and the second mounting hole 15. When the air inlet member 30 is in the air inlet position, the first mounting hole 51 is in communication with the ambient environment and the air passage 33. At this time, the air passage 33 on the air inlet member 30 is in communication with the first mounting hole 51 on the fixed plate 50, so that ambient air enters the air passage 33 through the first mounting hole 51, and the air inlet channel is in communication with the ambient environment. When the air inlet member 30 is in the air cut-off position, the first mounting hole 51 is disconnected from the air passage 33. That is, the air inlet member 30 moves downwardly, and the air passage 33 is no longer in communication with the first mounting hole 51, thereby cutting off the communication between the ambient environment and the air inlet channel.

[0049] Further, the fixed plate 50 comprises a plate body 52 and a convex ring 54. The plate body 52 is fixedly arranged on the water tank 10, and the convex ring 54 is arranged on the side of the plate body 52 away from the water tank 10. The first mounting hole 51 comprises a main hole 512 penetrating through the convex ring 54 and the plate body 52, and an air inlet 514 arranged on the outer circumferential side of the convex ring 54 and in communication with the main hole 512. The air inlet member 30 penetrates through the main hole 512 and extends into the second mounting hole 15 and the accommodating cavity 11. The air passage 33 is in alignment with or out of alignment with the air inlet 514 along with the telescopic movement of the air inlet member 30. In this way, the air inlet member 30 is arranged on the main hole 512 and the second mounting hole 15 and is telescopically arranged relative to the water tank 10. During the telescopic movement, the air passage 33 moves up and down relative to the convex ring 54. When the air passage 33 moves to the air inlet 514 on the outer circumferential side of the convex ring 54 to be in communication with the air inlet 514, ambient air can enter the air inlet channel through the air inlet 514 and the air passage 33. When the air passage 33 moves into the accommodating cavity 11 to be completely out of alignment with the air inlet 514, ambient air cannot enter the air passage 33 through the air inlet 514, thereby cutting off the communication between the ambient environment and the air inlet channel.

[0050] Referring to Figures 5-6In some embodiments, the mop module 100 further comprises a sealing member 70, which is tightly sleeved on the air inlet member 30 and abuts between the fixing plate 50 and the water tank 10. Thus, when the air inlet member 30 is moved to the air inlet position, the air passage 33 is located in the accommodating cavity 11 of the water tank 10, and the sealing member 70 tightly sleeved on the air inlet member 30 can block external air from entering the accommodating cavity 11 through the gap around the air inlet member 30, thereby improving the sealing effect and preventing air from entering when the mop module 100 is not used.

[0051] In an embodiment of the present application, a cleaning device is also provided, which comprises the above-described mop module 100. The mop module 100 comprises a water tank 10 and an air inlet member 30. The water tank 10 has an accommodating cavity 11 formed inside. The air inlet member 30 has an air inlet passage formed thereon and is telescopically arranged on the water tank 10. The air inlet member 30 has an air inlet position and an air cut-off position on the telescopic path thereof. When the air inlet member 30 is at the air inlet position, the air inlet passage is in communication with the accommodating cavity 11 and the outside, so as to allow external air to enter the inside of the water tank 10, thereby achieving air pressure balance inside and outside the water tank 10 and preventing the water tank 10 from being unable to discharge water due to too small internal air pressure. When the air inlet member 30 is at the air cut-off position, the air inlet passage is disconnected from the outside, so as to stop the water tank 10 from discharging water.

[0052] When the user needs to mop, the air inlet member 30 can be moved to the air inlet position, so that the accommodating cavity 11 inside the water tank 10 is in communication with the outside through the air inlet passage on the air inlet member 30. During the process of discharging water from the water tank 10, external air can continuously enter the accommodating cavity 11, so as to maintain air pressure balance inside and outside the water tank 10. The cleaning liquid in the water tank 10 can be evenly and orderly seeped out to supply water to the mop cloth at the bottom, thereby preventing the water supply process from being interrupted due to too small internal air pressure of the water tank 10 and improving the water discharge uniformity of the water tank 10. When the user finishes mopping or does not need to mop, the air inlet member 30 can be moved to the air cut-off position. The air inlet passage of the air inlet member 30 is blocked, and external air is blocked outside the water tank 10 and cannot enter the accommodating cavity 11 of the water tank 10. The cleaning liquid in the water tank 10 cannot seep out under the pressure of the external atmosphere, so as to close the water seepage function and prevent the mop module 100 from leaking when not mopping.

[0053] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but it should be considered that any combination of the technical features is within the scope of the present disclosure as long as the combination does not exist contradictory.

[0054] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
