Detailed Description

To explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following detailed description is made with reference to the accompanying drawings. The up, down, left, right, front, and rear positional relationships described in this embodiment correspond to the respective positional relationships shown in fig. 1, respectively. The floor cleaning equipment is used for cleaning and absorbing dust on the floor to be cleaned, and can be a wet and dry dust collector or a floor cleaning machine.

As shown in fig. 1 and 2, the wet and dry cleaning head includes a cleaning head body 11 capable of moving on a floor to be cleaned, a rotary coupling head 113 coupled to the cleaning head body 11, a suction passage 112, and a wet type floor-mopping device 12 fixedly mounted on the cleaning head body 11. Wherein, a part of the suction passage 112 is received in the cleaning head body 11, and another part is disposed on the rotary joint 113. The bottom of the cleaner head body 11 is provided with two dust suction ports 111 facing each other in the front-rear direction. When the wet and dry cleaning head is used in a floor cleaning appliance, it is connected to the main body of the floor cleaning appliance via a rotatable connection 113, for example, a hose or a wand, and the suction channel 112 is capable of drawing particles such as dust from the floor to be cleaned into the suction opening 111 by the suction force of the suction unit. Of course, only one dust suction port 111 may be provided at the front of the cleaner head body 11, and the dust suction port 111 may be located at the front side of the wet type floor mopping device 12, so that the functions of sucking dust first and mopping floor later can be realized.

As shown in fig. 3 and 4, the wet mop 12 includes a floor 121 for mounting a mop cloth and a water service box 122. The lower portion of the water supply tank 122 has an open structure, and the bottom plate 121 is fixedly installed at the lower portion of the water supply tank 122 and closes the lower opening of the water supply tank 122, so that the water supply tank 122 and the bottom plate 121 enclose a water storage chamber. Of course, the base plate 121 and the water supply tank 122 may be integrally formed for the convenience of injection molding manufacturing.

In order to facilitate the addition of cleaning water by a user, the wet type floor mopping device 12 is detachably mounted on the cleaning head body 11. Specifically, the water supply tank 122 has two tank portions opposed to each other on the left and right and a connecting portion connecting the two tank portions, which is a hollow structure and is formed integrally with the two tank portions. The space between the two case parts forms a clamping groove, the cleaning head body 11 has a clamping portion adapted to the clamping groove, when the wet type floor mopping device 12 is installed on the cleaning head body 11, the clamping portion of the cleaning head body 11 is located in the clamping groove of the wet type floor mopping device 12, and the water supply tank 122 is located at the top of the cleaning head body 11. The water supply tank 122 is provided at an upper portion thereof with a water filling port 134, and a cap 135 is provided at the water filling port 134.

Of course, in order to facilitate installation of the mop cloth, it is not necessary to detach all of the wet type mopping device 12 from the cleaning head body 11, but it is only necessary to fix the water supply tank 122 and the cleaning head body 11 to each other and detachably install the bottom plate 121 on the bottom of the water supply tank 122. Specifically, the bottom plate 121 and the water supply tank 122 are connected by a snap, the lower edges of the side wall plates of the water supply tank 122 form a connecting portion, a connecting groove which is circumferentially arranged and matched with the lower edge of the side wall plate of the water supply tank 122 is formed in the bottom plate 121, and a waterproof sealing rubber strip is arranged in the connecting groove.

The bottom plate 121 is provided with a water outlet 124, and the bottom plate 121 is provided with a drainer 14 communicated with the water outlet 124. When the mop cloth is mounted on the lower part of the floor 121, the mop cloth covers the outside of the drainer 14, and the cleaning water in the water storage compartment can be guided onto the mop cloth via the drainer 14, thereby moistening the mop cloth.

In order to facilitate that the cleaning water in the storage compartment can easily enter the drainer 14 to be guided onto the mop. The water supply tank 122 is provided with an air inlet 125 for communicating the external environment with the internal water storage chamber, and the air inlet 125 is provided on the cover 135. A check valve 131 is installed at the air inlet 125, and the check valve 131 allows only external air to enter the water service tank 122 from the outside, but does not allow air and/or cleaning water in the water service tank 122 to escape from the inside of the water service tank 122 to the external environment. This makes the cleaning water in the water supply tank 122 not leak to the floor to be cleaned through the air inlet 125 even if the water supply tank 122 is in an inverted state, thereby effectively avoiding the defect of secondary pollution to the floor to be cleaned when the user changes the cleaning water.

Of course, the supply tank 122 may be a totally enclosed structure, i.e., a structure in which the air inlet 125 is not provided, and cleaning water in the storage tank is guided onto the mop cloth by using only the capillary action of the drainer 14, thereby wetting the mop cloth.

In order to prevent the user from continuing to guide the water in the service tank 122 to the mops through the outlet 124 after finishing the mopping operation, the water content of the mops is excessive, thereby leaving a large water spot on the floor to be cleaned. As shown in fig. 4 and 5, a valve 127 for opening and closing the water outlet 124 is installed at the water outlet 124, and an actuator 126 for a user to operate and drivingly connected to the valve 127 is provided at an upper portion of the water supply tank 122. In use, a user actuates the valve 127 to open or close the water outlet 124 on the bottom plate 121 by operating the actuator 126.

Specifically, the water supply tank 122 is provided with a mounting hole 130, the valve 127 includes a plug 128 and a spring 129 mounted in the mounting hole 130, one end of the spring 129 is connected to the plug 128, the other end thereof is connected to the mounting hole 130, and a seal ring 133 is mounted on the lower end of the plug 128. The operating member 126 is a push button member, one end of which is attached to the water supply tank 122 via a rotating shaft 132, and the other end constitutes a trigger portion to be pressed or stepped by a user, and an upper end of the plug 128 is in close contact with the push button member. Of course, the actuating member 126 is not limited to the button-type rotating member, and may be a moving member, and the structure of the valve 127 is not limited to the plug moving in the up-and-down direction, and may also be a cover plate moving in the horizontal direction, for example, the moving member and the cover plate are fixedly connected, and when in use, the user operates the moving member to drive the cover plate to move in the horizontal direction, so that the cover plate and the water outlet 124 are staggered or opposite to each other, thereby opening or closing the water outlet 124.

The structural composition and application of the water drainer 14 will be described in detail with reference to fig. 2, 4-10.

As shown in fig. 2, the drainer 14 is installed at the lower part of the bottom plate 121, and as shown in fig. 4 and 5, a groove 123 is provided at the lower part of the bottom plate 121, the drainer 14 is accommodated in the groove 123, and the lower edge of the drainer 14 is almost flush with the lower surface of the bottom plate 121, so that when the mop is installed on the bottom plate 121, the mop does not appear uneven, which is beneficial to close contact between the mop and the ground to be cleaned, and the cleaning effect is improved.

As shown in FIG. 6, the launch device 14 includes a housing 141, a partition 146, and an absorbent member 140 that includes an absorbent core 148. The housing 141 is formed by fastening an upper cover 142 and a lower cover 143, and as shown in fig. 10, a cavity 145 is defined between the upper cover 142 and the lower cover 143. The baffle 146 and the absorbent core 148 are both located in the cavity 145, and the baffle 146 is located on the upper portion of the absorbent core 148. The absorbent core 148 is made of a material having good absorbent properties, such as absorbent core resin, cellulose, polyacrylamide, absorbent cotton, sponge, silica gel, etc.

In order to fasten the partition 146 and the water-absorbing core 148 in the cavity 145 after the upper cover 142 and the lower cover 143 are fastened to each other, as shown in fig. 8, a plurality of positioning grooves 155 and a plurality of downward extending protrusions 151 are disposed on the upper cover 142 along the length direction thereof, and the plurality of protrusions 151 and the plurality of positioning grooves 155 are disposed adjacent to each other in pairs, that is, one protrusion 151 is disposed between every two positioning grooves 155. The lower cover 143 is provided with water outlets 150 along the length direction thereof for inserting the plurality of protrusions 151 and a plurality of positioning protruding columns 152 adapted to the plurality of positioning grooves 155, the plurality of water outlets 150 and the plurality of positioning protruding columns 152 are arranged adjacent to each other, that is, one water outlet 150 is arranged between every two positioning protruding columns 152. The partition plate 146 is provided with a first positioning hole 153 along the length direction thereof for passing the plurality of positioning protruding columns 152 and a plurality of through holes 147 for passing the plurality of protruding blocks 151, the plurality of first positioning holes 153 and the plurality of through holes 147 are arranged adjacently in pairs, that is, one through hole 147 is arranged between every two first positioning holes 153. The partition plate 146 is further provided with a plurality of vertically penetrating small holes 156 through which cleaning water flows through the partition plate 146, and each small hole 156 is integrally formed with the corresponding first positioning hole 153. The absorbent member 140 is provided with a second positioning hole 154 along the length direction thereof for passing the plurality of positioning posts 152.

As shown in fig. 6, 7 and 9, when the absorbent core 148 and the partition 146 are assembled into the casing 141, the positioning boss 152 on the lower cover 143 passes through the second positioning hole 154 on the absorbent member 140 and the first positioning hole 153 on the partition 146 in sequence, and is finally inserted into the positioning groove 155 on the upper cover 142; meanwhile, the plurality of protrusions 151 of the upper cover 142 pass through the plurality of through holes 147 of the partition 146 and are inserted into the plurality of outlet holes 150 of the lower cover 143, and during this, the water absorption core 148 is pressed into the plurality of outlet holes 150 by the plurality of positioning protrusions 151 of the upper cover 142 and is partially exposed from the outlet holes 150.

In the above structure, the housing 141 of the drainer 14 is a split structure in which the upper cover 142 and the lower cover 143 are detachably connected. Of course, for ease of manufacture, the housing 142 of the drainer 141 may be designed as a one-piece structure with the cavity 145 left therein, and the wick 148 may be permanently defined within the housing 141. As such, when any component within the downcomer 14 is damaged, such as when the wick 148 becomes clogged, cracked, aged, etc., the user needs to replace the entire downcomer 14. In order to facilitate the user to selectively replace the internal components of the drainer 14 for the actual use, and mainly facilitate the user to replace the water-absorbing core 148, the housing 141 is preferably designed to be a split structure, not limited to a two-body structure of an upper cover and a lower cover, but may be a drainer housing composed of a plurality of parts, for example, an upper housing, a middle frame, and a lower housing, and the water-absorbing core 148 is fixed to the middle frame.

Referring to fig. 2, the drainer 14 can be detachably mounted on the lower portion of the bottom plate 121, that is, the outer contour of the drainer 14 is adapted to the groove 123 on the bottom plate 121. Alternatively, the upper cover 142 of the drainer 14 may be fixed to the bottom plate 121, and the remaining parts such as the lower cover of the drainer 14 may be designed to be detachable.

Since the cleaning water entering the drainer 14 generally fills the cavity 145 and then flows to the water-absorbing core 148 through the small holes 156 of the partition 146, in order to facilitate the cleaning water in the cavity 145 to be easily absorbed by the water-absorbing core 148, a water guide 149 is laid on the inner bottom surface of the cavity 145, the water guide 149 is in contact with the water-absorbing core 148, the water guide 149 also has good water absorption performance, and is integrally formed with the water-absorbing core 148, so that the cleaning water can be guided to the water-absorbing core 148.

In the above structure, the water absorbing material 140 is an integral structure, and the water guide 149 and the water absorbent core 148 are integrally formed. Certainly, in order to facilitate installation and replacement of a part of the water absorption cores 148, the water absorption cores 148 may also be a split structure, that is, a plurality of water absorption cores 148 may be provided, the water guide 149 connects the plurality of water absorption cores 148 together, the water guide 149 is sleeved on a plurality of positioning convex columns 152 on the inner wall surface of the casing 141, and each water absorption core 148 is in contact with the water guide 149, so that the cleaning water flowing to the water guide 149 can be guided to the plurality of water absorption cores 148.

Because only one water inlet 144 is formed on the upper cover 142, the cleaning water entering the drainer 14 from the water inlet 144 flows from the side close to the water inlet 144 to the side far from the water inlet 144, so that the water flow reaching the water-absorbing core 148 is not uniform, and finally the cleaning water seeping from each water outlet 150 is not uniform, so that the problem that some parts of the mop are wetted and some parts are not wetted occurs, in order to avoid this, the upper surface of the partition plate 146 is preferably designed to be an inclined surface, i.e., the upper surface inclines downwards from the side close to the water inlet 144 to the side far from the water inlet 144, so that the flow rate of the cleaning water entering the drainer 14 is slow at the side close to the water inlet 144 and fast at the side far from the water inlet 144, and the overall effects are obtained, namely, the water outlet rates of the water outlets 150 of the drainer 14 are basically uniform, the wetting effect is good. Of course, besides the upper surface of the partition 146 being designed as an inclined surface, a plurality of water inlets 144 may be disposed on the upper cover 142 along the length direction thereof, so as to make the water outlet rates of the water outlet holes 150 of the water outlet 14 uniform.

Fig. 11-14 illustrate another embodiment of a wet floor mop 12, which includes several other aspects of the present invention. It should be understood that these aspects may also be applied to the above-described embodiments or combined with the above-described features to constitute new embodiments. In fig. 11 to 14, the same reference numerals as in fig. 1 to 10 are used to designate the same or similar parts as in the embodiment shown in fig. 1 to 10.

As shown in fig. 11, the wet mop 12 includes a floor 121 and a water supply tank 122, which are similar to those shown in fig. 2. Two fasteners 22 are provided on each of the front and rear edges of the base plate. In the illustrated embodiment, each fastener 22 is in the form of a hook having a recess 221 facing the center of the base plate 121. Corresponding latches are provided on a rear face of the front suction part and a front face of the rear suction part (not shown in the drawings) of the cleaner head body 11, respectively. When the wet mop 12 is mounted to the cleaning head body 11, the catch provided on the cleaning head body 11 snaps into the recess of the locking member 22 provided on the base plate 121. In addition to, or instead of, the snap fit formed by the catch of the water tank and the catch of the cleaning head body 11, such a fit helps ensure that the wet mop 12 is secured to the cleaning head body 11. Furthermore, the locking member 22 also prevents the mop swab from completely covering the floor 121.

As shown in fig. 12, an exhaust pipe 24 protruding from the upper surface of the bottom plate 121 and extending above the maximum filling level of the water supply tank 122 is provided on the bottom plate 121. The top surface of the drainer 14 is provided with a connection port to the exhaust pipe 24. Then, the exhaust pipe 24 communicates the cavity 145 formed inside the drainer 14 with the water supply tank 122. As shown in fig. 4 and 5, the floor 121 has only one water outlet 124, and water exits the supply tank 122 through the water outlet 124 and enters the cavity 145 of the downcomer 14. Air that would otherwise be trapped in the cavity 145 may be difficult to vent from the outlet 124, and thus filling of the cavity 145 may be impeded. When filling the cavity 145, the vent tube 24 allows air present in the cavity 145 to be vented, thereby facilitating filling.

Also shown in FIG. 12, within cavity 145 is at least one interior wall 26, in this embodiment, floor 121 integrates the upper cover of lower water collector 14, which is an elongated protrusion that protrudes inwardly from the interior surface of the upper cover. The inner wall 26 occupies a portion of the volume of the cavity 145 and thereby reduces the volume of the cavity 145. Thus, when valve 127 is actuated to its open position, water can fill cavity 145 and wet the mop faster. In other words, the time from manually actuating the valve 127 until the mop is wetted by the water flowing out of the outlet opening 150 is shortened. The number and location of the inner walls 26 can be modified as desired. In addition, the inner wall 26 also serves as a reinforcing element for the bottom plate 121.

As can be seen from fig. 12, the drain valve 127 is provided with a lower seal 133 and an upper seal 34, the O-ring for radial sealing forming the upper seal and the gasket with the axial extension 341 for axial sealing forming the upper seal to reduce the force required to operate the plug 128 of the valve 127. In the embodiment shown in fig. 12, the valve 127 is completely contained within the mounting bore 130. The lower seal 133 and the upper seal 34 are both located between the plug 128 and the mounting hole 130 of the valve 127.

Unlike the previous embodiment shown in fig. 1 to 10, in the embodiment shown in fig. 11 to 14, the cover 135 does not include an air intake hole visible from the outside, nor a check valve, but includes an air inlet 38 opened to the inside of the water service box 122 and an air inlet opening 364 opened to the outside of the water service box 122 and an air intake passage extending therebetween. The air inlet passage is formed by a flow guide shape 36 provided on the cover 135. The lid 135 includes a lid member 136 and an inner liner member 138 mounted on the lid member 136. The deflector shape 36 is disposed on the top surface of the cover member 136 and protrudes downward. In the illustrated embodiment, the deflector shape 36 includes an inner skirt 361 that generally constitutes a rectangular profile and a rib 362 that connects the screw hole 33 and the inner skirt 361. The inner lining member 138 is mounted on the bottom of the cover member 136 and includes a bottom plate provided with the air inlet 38 and an outer skirt 37 projecting downward from the bottom plate and surrounding the air inlet 38. The lining member 138 is fixed to the cover member 136 by, for example, bolts (not shown) which are first passed through the mounting holes 32 provided in the bottom plate of the lining member and then tightened into the screw holes 33 provided in the corresponding positions of the cover member 136. In the illustrated embodiment, the mounting hole 32 is located at the center of the base plate.

When the cover member 136 and the liner member 138 are bolted together, the outer skirt 37 is positioned over the inner skirt 361, and the edge S of the outer skirt shown in FIG. 13 is opposite the edge S' of the inner skirt. The height of the inner skirt 361 and ribs 362 are set so that they can contact the floor of the liner component 138 after installation, whereby water is difficult to pass between them and the floor of the liner component. As shown in fig. 13, in this embodiment, four ribs 362 are distributed in a cross shape centering on the screw hole 33. The ribs 362 form a barrier to water and/or air. It will be appreciated that the number and distribution of ribs may vary according to actual requirements. When the cover member 136 and the liner member 138 are installed, the air intake 38 is positioned between two ribs 362, one of which is partially hollowed out to form a central air opening 363 in the air channel. Another adjacent one of the hollowed out ribs is also hollowed out to form a middle air opening 363. The inner skirt 361 is provided with a first recess 364 and the outer skirt 37 is provided with a second recess 374 at corresponding locations to form said air inlet opening. The first notch 364 extends over the entire height of the inner skirt 361, while the second notch 374 extends over part of the height of the outer skirt. Preferably, as shown in fig. 13, the outer skirt 37 further includes an inwardly projecting stop 373, the stop 373 being inserted into the first recess 364 of the inner skirt 361 when the cap is installed. The first notch 364 is located between the other two ribs 362. In other words, the intake port 38 and the intake opening are located at two diagonal corners in the quadrant defined by the four ribs, respectively. Thus, the air introduced into the cover 135 first passes through the air inlet openings formed by the

recesses

364 and 374, then sequentially passes through the middle air openings 363 hollowed out in two adjacent ribs 362, and finally enters the water service box through the air inlet 38. However, conversely, when the water supply tank is inclined and the liquid therein tends to leak from the cover 135, the liquid may be trapped between the cover member 136 and the liner member 138 by the baffle plate constituted by the rib 362 and the stopper 373. In another preferred embodiment, the intermediate air opening 363 is located proximate to the top surface of the cover member 136 to more effectively trap liquid.

To lock the discharge valve 127 in its closed or open position, a cam shape 40 is formed on top of the plug 128 of the discharge valve 127. The top portion includes a stepped surface comprising a high surface 45 and a low surface 46, and the high and low surfaces are connected by a cam surface 41. As shown in fig. 14, with the discharge valve in the open position, the lever arm 50 of the actuator 129 rests on the lower surface 46 at the top of the plug 128. To switch the valve 127 to its closed position, the actuating member 129 should rotate about its axis in a clockwise direction. For this purpose, the first edge 42 of the lever arm 50 of the actuating element 129 is pressed against the cam surface 41. During the forced passage of the cam surface 41 and the first side 42, the plug 128 moves downwardly against the spring force which tends to push the drain valve plug upwardly. Once the cam surface 41 is forced past, the lever arm 50 rests on the high surface 45 of the stepped surface and the plug 128 of the valve blocks the outlet 125 downwardly, i.e., places the valve in a closed position. Preferably, the high surface 45 at the top of the stopper 128 is provided with a protrusion 43 near the cam surface 41. To open the drain valve 127, the operating member 129 should be rotated in a counterclockwise direction. Likewise, the lever arm 50 is pressed with its second edge 44 against the projection 43. When the projection 43 and second edge 44 are forced past, the plug 128 is urged upward by the spring force and the lever arm 50 returns to the lower surface 46 of the stepped surface, thereby opening the valve 127. In this embodiment, the cam shape 40 includes a cam surface 41 and a protrusion 43.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
