[0033] Before the present utility model is described in detail, it should be noted that in the following description, similar components are denoted by the same reference numerals.

[0034] Refer to Figure 2 and Figure 3 , a first embodiment of the mop cleaning device of the present utility model is applicable to cleaning a mop head 91 of a mop 9, and the mop head 91 is cotton and strip-shaped.

[0035] The first embodiment includes a base unit 1, a water pumping unit 2, a rotating unit 6 and a water guiding unit 7.

[0036] The base unit 1 includes a housing wall 11 that defines a water storage tank 111 and a cleaning tank 112 that is separated from the water storage tank 111 and is used to accommodate the mop head 91.

[0037] The water pumping unit 2 is installed on the base unit 1. The water pumping unit 2 has a piston cylinder 3, a water inlet pipe 4 that communicates the inside of the piston cylinder 3 with the water storage tank 111, and a water outlet pipe 5 that communicates the inside of the piston cylinder 3 with the cleaning tank 112.

[0038] Refer to Figures 4 to 7 , the piston cylinder 3 has a cylinder body 31 that defines a piston space 311, the 5 / 8th page

[0039] a water pumping space 312 and a perforation 313, a piston member 32 movably disposed in the piston space 311, a water inlet hole 33 communicating with the water inlet pipe 4, a water outlet hole 34 communicating with the water outlet pipe 5, a water inlet valve 35 connected to the cylinder body 31 and defining the water inlet hole 33 to communicate the water pumping space 312 with the water inlet pipe 4, a water outlet valve 36 connected to the cylinder body 31 and defining the water outlet hole 34 to communicate the water pumping space 312 with the water outlet pipe 5, a pedal 37 pivotally connected between the cylinder body 31 and the piston member 32, a spring 38 installed between the pedal 37 and the cylinder body 31 and providing a restoring force for the pedal 37, a pressure relief hole 39 communicating the piston space 311 with the outside of the cylinder body 31, and a pressure relief pipe 40 communicating the pressure relief hole 39 with the cleaning tank 112. The piston space 311 communicates with the water pumping space 312 and the perforation 313. In this embodiment, both the water inlet valve 35 and the water outlet valve 36 are one-way valves. The pressure relief hole 39 and the pressure relief pipe 40 are used to jointly adjust the pressure inside the piston cylinder 3.

[0040] It is worth mentioning that in a variation of this embodiment, the piston cylinder 3 further has an auxiliary spring (not shown in the figure) disposed between the inner side of the cylinder body 31 and the bottom of the piston member 32, thereby strengthening the restoring force provided to the pedal 37.

[0041] The water inlet valve 35 has a first valve body 350 that extends along a first axis L1 and is hollow, and a first seal 351 located within the first valve body 350. The first valve body 350 has a first large-aperture section 353 and a first small-aperture section 354 connected to the first large-aperture section 353. The first seal 351 is movably disposed in the first large-aperture section 353 and is used to close the water inlet hole 33 so that the water inlet valve 35 is in a closed state. In this embodiment, the first seal 351 is a spherical seal or a conical seal, and when not under force (such as Figure 4 ), it naturally droops to open the water inlet hole 33.

[0042] Referring to Figures 8 to 11 , it is worth mentioning that in a variant of this embodiment, the water inlet valve 35 can be in another form. The water inlet valve 35 has the first valve body 350 and a first gasket 355 disposed on the side of the first valve body 350 opposite to the water pumping space 312. The first gasket 355 constantly returns to close the water inlet hole 33 so that the water inlet valve 35 is in a closed state. The specific implementation of the first gasket 355 of the water inlet valve 35 in the variant of this embodiment is similar to that of the water outlet valve 36 of this embodiment, which will be described together later.

[0043] Referring to Figures 4 to 7 , the water outlet valve 36 has a second valve body 360 that extends along a second axis L2 perpendicular to the first axis L1 and is hollow, and a second gasket 364 disposed on the side of the second valve body 360 opposite to the water pumping space 312. The second gasket 364 constantly returns to close the water outlet hole 34 so that the water outlet valve 36 is in a closed state.

[0044] Referring to Figures 8 to 11 , it is worth mentioning that in a variant of this embodiment, the water outlet valve 36 can be in another form. The water outlet valve 36 has the second valve body 360 and a second seal 363 located within the second valve body 360. The second valve body 360 has a second large-aperture section 361 and a second small-aperture section 362 connected to the second large-aperture section 361. The second seal 363 is movably disposed in the second large-aperture section 361 and is used to close the water outlet hole 34 so that the water outlet valve 36 is in a closed state. The second seal 363 is a spherical seal or a conical seal.

[0045] In addition, if the water outlet valve 36 of this embodiment is not provided, and only the water inlet valve 35 is in an open state or a closed state respectively when the piston member 32 is in a water inlet position or a water outlet position (to be described together later), a certain degree of water pumping and drainage effects are still generated compared with the prior art.

[0046] Refer to Figure 2 and Figure 3 , the rotating unit 6 is disposed on the base unit 1 and has a rotating shaft 61 pivotally disposed on the base unit 1 in a rotatable manner. The rotating shaft 61 has a linking portion 611 extending into the cleaning tank 112 and adjacent to the water outlet pipe 5. The linking portion 611 is used for detachably engaging the mop head 91 so that the mop head 91 can rotate in the cleaning tank 112. Specifically, when a grip rod 92 of the mop 9 is pressed down to generate a linear displacement, the mop head 91 and the linking portion 611 are driven to rotate. The mop 9 is a prior art (as shown in patents such as Taiwan, China Utility Model Patent Certificate Nos. TW M368410, TW M415686, TW M446606, etc.), and is not the focus of this utility model, and its detailed structure will not be described herein.

[0047] The water guiding unit 7 is located in the cleaning tank 112 and has a positioning cover 71 located in the cleaning tank 112 and installed on the shell wall 11, a water guiding member 72 disposed on the top surface of the positioning cover 71, and a brush set 73 adjacent to the water guiding member 72 and disposed on the top surface of the positioning cover 71. The positioning cover 71 has a water guiding groove 711 communicating with the water outlet pipe 5. The water guiding member 72 extends along the top surface of the positioning cover 71 and has a plurality of water spraying holes 721 corresponding in position and communicating between the water guiding groove 711 and the cleaning tank 112. The linking portion 611 of the rotating shaft 61 penetrates the positioning cover 71 and protrudes from the top surface of the positioning cover 71.

[0048] During actual operation, the piston member 32 can move relative to the cylinder body 31 between the water inlet position (such as Figure 4 and Figure 5 ) and the water outlet position (such as Figure 6 and Figure 7 ).

[0049] Refer to Figure 6 and Figure 7 , first, the user steps on the pedal 37 to move the piston member 32 to the water outlet position. At this time, the piston member 32 is adjacent to the water pumping space 312. During this process, an outward discharge force is generated, and the water outlet valve 36 is in an open state and the water inlet valve 35 is in a closed state, thereby discharging the air in the water pumping space 312.

[0050] Refer to Figure 4 and Figure 5 , then, the user releases the force applied to the pedal 37, and uses the spring 38 to provide a restoring force for the pedal 37, so that the piston member 32 moves to the water inlet position, at this time the piston member 32 is away from the water pumping space 312. During this process, a suction force from the outside to the inside is generated, and the water inlet valve 35 is opened and the water outlet valve 36 is closed, and then water is taken from the water storage tank 111 through the water inlet pipe 4 and the obtained water is pre-placed in the water pumping space 312.

[0051] Refer to Figure 6 and Figure 7 , finally, the user steps on the pedal 37 again, so that the piston member 32 moves to the water outlet position, at this time the piston member 32 is adjacent to the water pumping space 312. During this process, a discharge force from the inside to the outside is generated, and the water outlet valve 36 is opened and the water inlet valve 35 is closed, and then the water pre-placed in the water pumping space 312 is discharged into the cleaning tank 112 through the water outlet pipe 5 to clean the mop head 91 located in the cleaning tank 112.

[0052] Refer to Figure 12 , Figure 13 and Figure 14 , a second embodiment of the mop cleaning device of the present invention is also applicable to cleaning the mop head 91. The second embodiment also includes the base unit 1, the water pumping unit 2, the rotating unit 6 and the water guiding unit 7.

[0053] The difference between the second embodiment and the first embodiment is that the piston member 32 of the water pumping unit 2 has a rod portion 321 pivotally connected to the pedal 37, and a head portion 322 pivotally connected to the rod portion 321 and movably limited in the piston space 311. The rod portion 321 is movably limited in the through hole 313 defined by the cylinder body 31.

[0054] In this embodiment, by pivotally connecting the rod portion 321 between the head portion 322 and the pedal 37, the smoothness of the movement of the head portion 322 relative to the cylinder body 31 when the piston member is driven by the pedal 37 is improved.

[0055] Therefore, the mop cleaning device of the present invention can achieve the following effects:

[0056] Page 8 / 8

[0057] (1) By providing the water pumping unit 2, the piston member 32 of the piston cylinder 3 can move relative to the cylinder body 31 between the water inlet position and the water outlet position, so that the water inlet valve 35 and the water outlet valve 36 are alternately opened, respectively performing the actions of taking water from the water storage tank 111 and discharging water into the cleaning tank 112, thereby achieving good water pumping and draining effects.

[0058] (2) By providing the first seal 351 or the first gasket 355 of the water inlet valve 35 to close the water inlet hole 33 when the piston member 32 is in the water outlet position, it cooperates to achieve a good draining effect.

[0059] (3) By providing the second gasket 364 or the second seal 363 of the water outlet valve 36 to close the water outlet hole 34 when the piston member 32 is in the water inlet position, it cooperates to achieve a good water pumping effect.

[0060] In summary, the mop cleaning device of the present utility model can achieve the purpose of the present utility model by achieving good water pumping and draining effects through a simple structure.

[0061] The above is only an embodiment of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby. That is, all simple equivalent changes and modifications made according to the claims and the content of the specification of the present utility model still fall within the scope of the present utility model.
