In the exemplary embodiments of the mop head in Figures 6A and 6B, the mop head 400 may be configured to be rotated to a first position 600 relative to the connector assembly 300. In the exemplary embodiments of the mop head in Figures 6c and 6d, the mop head 400 may be configured to be rotated to a second position 700 relative to the connector assembly 300. [ 6A, when there is a mop head in the first position 600, the first opposing face 510 of the mop head 400 may be oriented upward, To an angle 530 of < / RTI > . 6B, the second opposing surface 520 of the mop head 400 may be oriented upward and rotated at a first predetermined angle 530 with respect to the connector assembly 300. As shown in FIG. 6C, the first opposing face 510 of the mop head 400 may be oriented upward when the mop head is in the second position 700, To an angle 540 of the angle. 6D, the second opposing face 520 of the mop head 400 may be oriented upward and rotated at a second predetermined angle 540 relative to the connector assembly 300.

As shown in FIG. The first predetermined angle 530 to the mop head may be acute (e.g., FIGS. 6A and 6B) and the second predetermined angle 540 to the mop head may be an obtuse angle (e.g., 6C and 6D).

In the steam blast operation mode 600, the steam discharge speed may be higher than the general area cleaning mode 700, while the range of the area is wider than the steam blast operation mode 600 in the general area cleaning operation mode 700 Can be seen. As such, the steam blasting mode of operation can be effective and efficient in cleaning or treating hard to remove or dirty stains. It can also be seen that in the steam blast operation mode 600, the steam blast is dependent on the rate and the hydration that can break stubborn stains. For example, considering a stain that is difficult to remove as a stacked layer, steam may begin to hydrate the top layer speckle, causing the top layer speckle to move out due to the rate of steam discharge, exposing the next layer of stain to be hydrated .

For example, by means of gravity, manually applied force, mechanical force actuated on the implement, or any other suitable means, the changeover mechanism 8800 can be moved to the first or second switch mechanism position. In the second switching mechanism position, the switching mechanism 8800 may block the first connector steam path 8205 without blocking the second connector steam path 8206. [ This allows steam to be supplied to the mop head 8300 through the second connector steam path 8206. [ When the mop head 8300 is rotated to the second position, the switching mechanism 8800 can be positioned at the first switching mechanism position. In the first switching mechanism position, the switching mechanism 8800 may block the first connector steam path 8205 while blocking the second connector steam path 8206. This allows steam to be supplied to the steam blast nozzle assembly 8400 through the first connector steam path 8205 and prevents steam from entering the mop head 8300.

8F, the diversion mechanism 8800 may include a sealing element such as a valve body 8802, a valve spring member 8801, an O-ring 8803, and the like. The valve body 8802 may include a first end portion and a second end portion. Adjacent the first end portion, the valve body 8802 can include first and second shoulders 8822 that extend outwardly of the valve body 8802. The first and second shoulders 8821, 8822 may be perpendicular to the valve body 8802. The O-ring 8803 is located at the intersection of the first shoulder 8821 and the valve body 8802 facing the first end portion. The position of the O-ring 8803 may not be considered to be limited. The diverter mechanism 8800 can be received in a valve packing assembly 8701 that accommodates a moveable baffle 8810. The first and second end portions extend into the groove which is a portion of the valve packing assembly in which the movable baffle 8810 is located and the second end portion of the valve body 8802 is in a position open to the valve spring member 8801 Can be biased.

The movable baffle 8810 may include a elongated baffle member 8812 having a first and a second end, a baffle spring member 8813 and three o-rings 8814, 8815, and 8816. The number of O-rings can vary. The movable baffle 8810 can be rotated vertically to the mop head 8300 and rotated vertically to the switching mechanism 8800. [ The first end of the elongate baffle member 8812 can be deflected to the open position by the spring member 8801. [ When there is a mob in the first position shown in Figure 8f, the movable baffle 8810 is in the first baffle position. At this time, the second end of the valve body 8802 moves out of the groove of the elongated baffle member blocking the second connector steam path 8206. In this position, the first and second shoulders of the switching mechanism, the first and second O-rings, move forward along the spring members to allow steam to flow through the first connector steam path 8205 To flow into the steam blast nozzle assembly 8400 through the steam blast nozzle assembly 8400. When the mop head 8300 is in the second position (not shown in FIG. 8F), the movable baffle 8810 may be in the second baffle position. At this time, the second end of the valve body 8802 extends into the groove of the elongated baffle member. The first and second shoulders of the switching mechanism 8800, the first and second O-rings completely block the first connector steam path 8205 while the second connector steam path 8206 remains open. As such, the steam moves into the mop head 8300 to allow general area cleaning.

As shown in FIG. 8F, the operating mechanism 8208 may be provided to regulate the movement of the switching mechanism from the first switching mechanism position to the second switching mechanism position. The operating mechanism 8208 may be operated manually in FIG. 8f, or it may be operated by any means such as levers, electrical means, automatic means, and the like. As shown in FIG. 8F, the operation mechanism 8208 may be provided to be connected to the connector assembly 8200. It is recognized that the position of the operation mechanism 8208 is not limited.

In another embodiment of the valve mechanism 8700 shown in Figures 8G-8H, in accordance with the principles described herein, the diversion mechanism 8800 can be configured in a variety of ways. In one embodiment, as shown in Figures 8G-8H, the switching mechanism 8800 includes a first valve 8901 and a second connector steam path 8206 that are at least partially disposed in the first connector steam path 8205, And at least partially disposed second valve 8902. The first valve 8901 may include a first valve body 8911 and a first spring member 8912. The first valve body 8911 may include a first end portion and a second end portion. Adjacent the second end portion, the first valve body 8911 may include first and second shoulders 8913 and 8914 extending outwardly from the first valve body 8911. The first and second shoulders 8913 and 8914 can be perpendicular to the first valve body 8911 and the second end portion of the first valve 8901 is biased to the open position in the first spring member 8912 .

The first spring member 8912 may be located adjacent to the spring nozzle assembly 8400 in the first connector steam path 8205. [ The first O-ring 8915 may be positioned toward the first end portion at the intersection of the first shoulder 8913 and the first valve body 8911. [ In addition, the second O-ring 8916 can be positioned toward the first end portion close to the intersection of the second shoulder 8914 and the first valve body 8911.

Similarly, the second valve 8902 may include a second valve body 8921, a second valve spring member 8922, and the like. The second valve body 8921 may include a first end portion and a second end portion. Adjacent to the second end portion, the second valve body 8921 can include third and fourth shoulders 8923 and 8924 extending outwardly from the second valve body 8921. The third and fourth shoulders 8923 and 8924 may be perpendicular to the second valve body 8921. The third O-ring 8925 can be positioned toward the first end portion at the intersection of the third shoulder 8923 and the second valve body 8921. In addition, the fourth O-ring 8926 can be positioned toward the first end portion close to the intersection of the fourth shoulder 8924 and the second valve body 8921. The first and second valves 8901, 8902 may be arranged in a manner that forms a straight line. Here, the first end portion of the first valve 8901 and the first end portion of the second valve 8902 are in contact with each other. The first and second valves 8902 may be at an angle of 180 degrees to each other on the same axis.

The first and second O-rings 8915 and 8916 and the first and second shoulders 8913 and 8914 of the first valve body 8911 are configured such that when the diversion mechanism 8800 is in the first position, Path 8205 together. The third and fourth O-rings 8925 and 8926 and the third and fourth shoulders 8923 and 8924 of the second valve body 8921 are arranged such that when the diversion mechanism 8800 is in the second position, Path 8206 together. A switching mechanism 8800 with a movable baffle 8810 can be received in the valve packing assembly 8701. The second end portion of the second valve body 8921 may extend into the groove of the moveable baffle 8810.

The movable baffle 8810 may be positioned perpendicular to the diversion mechanism 8800. [ The movable baffle 8810 may be positioned in a manner that maintains the diverter mechanism 8800 in place. The movable baffle 8810 may include a elongated baffle member 8812, a groove 8813 on the elongated baffle member 8812, a spring member 8811 and two o-rings 8814 and 8815. [ The number of O-rings can be changed. The movable baffle 8810 may be positioned perpendicular to the mop head 8300. One end of the elongated baffle member 8812 is deflected to a position opened by a spring member 8811. [ The other end of the elongated fragrance baffle member 8812 may have two o-rings 8814 and 8815. [ As shown in Figures 8g and 8i, when the mop head 8300 is in the second position (see Figures 6c and 6d), the moveable baffle 8810 is in the second baffle position. Where the second end of the second valve body 8921 extends into the groove of the elongated baffle member 8812. Thus, the first valve body 8911 completely blocks the first connector steam path 8205, and the steam moves into the mop head 8300 to clean the general area. In this embodiment, the second connector steam path 8206 remains open to allow steam into the mop head 8300, allowing a general area cleaning operation mode 8303.

As shown in FIG. 8H, when the mop head 8300 is in the first position (see FIGS. 6A and 6B), the movable baffle 8810 is in the first baffle position. Here, the second end of the second valve body 8921 moves out of the groove 8813 of the elongated baffle member 8812. As such, the second valve body 8921 completely blocks the second connector steam path 8206, the first valve body 8911 moves so that the first connector steam path 8205 remains open, Blast nozzle assembly 8400 that allows for steam blast or jet blast 8405 from the first connector steam path 8205. [ The valve mechanism shown in Figures 8F-8I is not considered to be limiting.

8J-8P, in an exemplary embodiment of the steam mob 8000 of FIGS. 8A-8I, a scrubber assembly 8500 for rubbing operation with steam blast may be provided. This mechanism makes it possible to rub the area to be cleaned or treated with the steam blast, so that it is possible to easily and effectively erase dirt and hard-to-erase stains. In one embodiment, the scrubber assembly 8500 may extend at least partially into the connector receiving opening of the mop head 8300.

In one embodiment, the scrubber assembly 8500 can be coupled to the connector assembly 8200 either directly or indirectly. For example, the connector assembly 8200 and the scrubber assembly 8500 can move relative to the connector assembly 8200 independently of one another in a specific direction of the mop head 8300, or in cooperation with each other. In another embodiment, the scrubber assembly 8500 may be coupled directly or indirectly to the mop head 8300 or body.

The scrubber assembly 8500 includes a scrubber base 8501 having two sides of a first side 8502 and a second side 8503, at least one support arm 8505, 8506 and a scrub pad 8504, May include a rubbing member (as shown in Figure 8l) such as any instrument that allows rubbing of the surface. In one embodiment shown in Figure 8l, the scrub pad 8504 may be part of the cleaning pad 8309. Cleaning pad 8309 may be configured to allow scrubbing pad 8504 to enter when scrubbing assembly 8500 is in retract mode 8520 and may be configured to be cleaned when scrubbing assembly 8500 is in rubbing mode 8510 And can be configured to abut the surface. It can be appreciated that the scrub pad 8504 as part of the cleaning pad 8309 can eliminate alignment problems. For example, if the user incorrectly places the cleaning pad 8309 on the mop head 8300, when the scrubber assembly 8500 is deployed, the strut assembly will potentially descend down and will not make any contact with the floor And can be placed on top of the cleaning pad 8309. In another embodiment, the scrub pad 8504 can be detached from the cleaning pad 8309 and removably attached to the second side of the scrubber base 8501.

8J-8P, the scrubber assembly 8500 may include a scrubber base 8501 and a pair of support arms 8505, 8506 extending from the scrubber base 8501. In the exemplary embodiment shown in Figs. The support arms 8505, 8506 can be directly or indirectly connected to the connector assembly 8200 and can extend at least partially into the connector accommodation manifold. 8m, 8n, 8o, and 8p) can be configured to be in the collapsed position when the scrubber assembly 8500 is in the retract mode 8520 (mode 1), and each of the support arms 8505, 8506 (e.g., , And may be configured to be in an extended position when the scrubber assembly 8500 is in the rubbing mode 8510 (mode 2). This embodiment of the scrubber assembly 8500 can provide the advantage that when the scrub mode is not in effect, the scrub pads do not come into contact with the floor, preventing dust or debris from repositioning over the scrubbing area.

In the general area cleaning mode, when the steam flow is directed to the mop head 8300, the scrubber assembly 8500 is away from the retraction mode 8520, i.e., the area to be cleaned. In the steam blast mode 8401, when the steam flow is directed to the steam blast nozzle assembly 8400, the scrubber assembly 8500 is operated in the rubbing mode 8510, i.e., the rubbing member is brought into contact with the area to be cleaned or treated 8M, and mode 2). This allows surface rubbing with the steam blast. In one embodiment, the scrubber base is positioned adjacent to the steam blast nozzle assembly 8400, allowing the steam blast to come just before the scrubber is placed. This allows efficient removal of dust, dirt, stains and dirt on the area to be cleaned.

In one embodiment, the arrangement of the scrubber assembly 8500 can be adjusted by the orientation of the mop head 8300 relative to the connector assembly. The angular orientation of the mop head 8300 causing steam to be ejected out of the steam blast nozzle assembly 8400 may also activate the placement of the scrubber assembly 8500. The arrangement of the scrubber assembly 8500 can also be brought by any means, such as a lever mechanism, electrical means, or the like. As shown in Figures 8m (mode 1), 8n (mode 1) and 8o, when the mop head 8300 is in the general area cleaning mode 8303, i.e., in the second position, the scrubber assembly 8500 is in the retraction mode Lt; / RTI > In the second position, the mop head 8300 is at a second predetermined angle relative to the connector assembly 8200. [ . As shown in Figures 8m (mode 2), 8n (mode 2) and 8p, when the mop head 8300 is in the steam blast mode 8401, i.e., in the first position, the scrubber assembly 8500 is in the rubbing mode Lt; / RTI > The mop head 8300 is at a first predetermined angle relative to the connector assembly 8200.

FIG. 9 depicts an exemplary embodiment of a mop head 9100 that may be used for cleaning (or otherwise) cleaning or otherwise treating surfaces such as wood, tiles, marble, or reinforced floors. The mop head 9100 embodiments described herein may be used as a processing device to perform one or more functions other than cleaning or working surfaces. 9, one embodiment of the mop head 9100 may include a frame 9102, a lid 9104, a joint 9106, and at least one cleaning pad 9108.

In some embodiments, the inner surface of the cleaning pad 9108 may have a pocket 9110 that fits around the lead-out area of the lid 9104 to secure the cleaning pad 9108 to the lid 9104. In some embodiments, the instrument may include one cleaning pad 9108 attached to lid 9104. [ However, in other embodiments, the mechanism may include a plurality of pads attached to lid 9104. [ In one such embodiment, one pad is attached to each cover 9104. In other embodiments, the number of lids 9104 may be different. In some embodiments, the mop head 9100 may have two sides, with a lid 9104 on each side. In some embodiments, two surfaces can be used to clean the surface. As can be appreciated, other embodiments may employ other methods to allow the user to switch from using one or the other side of the mop head 9100. [

It will be appreciated by those skilled in the art that other means may be used as an alternative to securing the cleaning pad 9108 to the lid 9104 or in addition to the bag. For example, in some embodiments, an adhesive in the form of a velcro or velcro may be used to attach the cleaning pad 9108 to the lid 9104. However, as can be appreciated, various means can be used to attach the cleaning pad 9108 to the lid 9104.

Cleaning pads 9108 may be formed from a variety of materials. Other cleaning pad 9108 embodiments may be suitable for various types of surface treatments. In some embodiments, various embodiments of the cleaning pad 9108 may be replaceably attached to the cleaning lid 9104. For example, the first cleaning pad 9108 embodiment can be attached to the cover 9104, and the second cleaning pad 9108 embodiment can be used or replaced for other purposes. In an embodiment in which the treatment head 9100 includes a plurality of surfaces, the cleaning pad 9108 may be divided into areas corresponding to the faces of the treatment head 9100. [ Each area of the cleaning pad 9108 can be designed for a specific purpose. Then, the user can adjust the mop head 9100 to come to the desired side with respect to the cleaning surface.

11, 11a, 11b, 11c, and 11d, in some embodiments the lid 9104 is pivotally attached to the first portion 9150 of the frame 9102 of the mop head 9100. As shown in Figs. At this time, the lid 9104 can be configured to pivot relative to the frame 9102 between the open position and the closed position. The cover 9104 can be rotated to an open position for attachment and removal of cleaning pads 9108 and can be locked into a closed position for cleaning. In one embodiment, the lid 9104 can be used with hinges to attach to the frame 9102.

However, in alternative embodiments, other attachment mechanisms may be used to attach the cover 9104 to the frame 9102. [ The hinge or other attachment mechanism used to attach the lid 9104 to the frame 9102 may be located at other locations in other embodiments. In some embodiments, the lid 9104 may be rotated to an open or closed position relative to the hinge. Figure 11 depicts an embodiment of a mechanism with a lid 9104 in an open position. Fig. 12 depicts an embodiment of a mechanism with a lid 9104 in a closed position.

Figures 11-11d illustrate a side view of a frame 9102 that is hinged or pivotally connected to a first side or portion 9150 of the frame 9102 and which is releasably connected to a second side 9152 of the frame 9102 An embodiment is depicted. This embodiment allows the lid 9104 to rotate relative to the hinge on the first side 9150 such that the lid 9104 can be folded into the closed position and released to the second side 9152 of the frame 9102 Lt; / RTI > After removal of the cleaning pad 9108, after the cover 9104 is released from the second side 9152 of the frame 9102, the cover 9104 may be extended to the open position. In some embodiments, the first and second sides 9150 and 9152 of the frame 9102 are on opposite or opposite sides, as depicted in the embodiments of Figures 11-11d.

In one embodiment, lid 9104 is releasably connected to a first side 9150 of frame 9102 and joint 9106 is pivotally connected to a second side 9152 of frame 9102 . In such an embodiment, the first and second sides 9150 and 9152 may be opposed to each other.

The mop head 9100 embodiments depicted in Figures 12-12h further include a first lid 9104A and a second lid 9104B. The first lid 9104A and the second lid 9104B are arranged so that the first hinge axis 9200 (for the first lid 9104A) and the second hinge axis 9202 2 cover 9104B) of the frame 9102. The first side 9150 of the frame 9102, In various embodiments, various locking mechanisms may be used to releasably lock the covers 9104A, 9104B to the frame 9102 at the second side 9152 when the covers 9104A, 9104B are folded into the closed position Can be used. Other embodiments may utilize other release mechanisms to release the covers 9104A, 9104B in the frame 9102. [

As shown in Figures 12-12h, the push button release mechanism 9120 can be used to release the lids 9104A, 9104B so that the lid can be folded open and the cleaning pads 9108 can be removed . The button may be located on the frame 9102 of the mop head 9100 at various positions. Button 9120 may be located at various points on the mop head 9100 or on the cleaning mechanism.

As shown in Figures 13-13e, in one embodiment, the cleaning pads 9108 may be configured to include one or more foot tabs 9130. [ The frame 9102 may not be locked and the cover 9104 may be disassembled when the user presses upward on the frame 9102 and steps on the foot tab 9130 to hold the lid 9104 in place. As can be appreciated, the pressure on the top may be provided in other ways in other embodiments. However, in many embodiments, the mop head 9100 can be attached to a shaft or rod, and the user can apply pressure to the frame 9102 by simply pulling the rod or shaft up. When the specific pressure is reached, the lid 9104 falls from the locking mechanism and is folded open. Accordingly, the user can release and open the cover 9104 without touching the mop head 9100. [ In some embodiments, the pads may be removed with the same operation, and the user may remove the pads from the lid 9104 without touching the hands. In one such embodiment, cleaning pad 9108 is attached to lid 9104 by a pouch. Once the lid 9104 is expanded, the user can pull the shaft or rod and pull the lid 9104 out of the cleaning pad 9108. The cleaning pad 9108 is held in the ground by the foot tab 9130. Thus, the pad can be removed and the hands free. It is appreciated that other disassembly mechanisms may be used in other embodiments to disengage the cover 9104. Some of which have been discussed elsewhere herein, and may include levers, without limitation.

In another embodiment, the cleaning pad 9108 may be attached to the lid 9104 by an adhesive of the Velcro or other Velcro type. Cleaning pads 9108 may have foot tabs 9130. By stepping on the foot tab and pulling on the shaft or handle, the user can overcome the holding force of the Velcro and lift the mop head 9100 from the cleaning pad 9108. [ Accordingly, the mop head 9100 is detached from the cleaning pad 9108, and the cover 9104 is held in the closed position. This allows the user to remove old and potentially hot cleaning pads 9108 from the mop head 9100 without touching the cleaning pads 9108. [ And a new cleaning pad 9108 can be attached to the mop head 9100.

In one embodiment, the mop head 9100 may further include a connector assembly 9107. In some embodiments, the connector assembly 9107 can be used to connect the mop head 9100 to a shaft, handle, or rod. One embodiment of connector assembly 9106 is depicted in Figs. 15-15g. Connector assembly 9107 depicted in Figures 15-15g includes an upper portion 9107A and a lower portion 9107B. Connector assembly 9107 may further include joint 9106 configured to allow rotation about upper portion 9107A and lower portion 9107B relative to each other. In some embodiments, the lower portion 9107B may include a yoke 9160. [ The yoke 9160 can be received in the groove 9162 disposed in the frame 9102. [ In some embodiments, the mop head 9100 may be rotated relative to the yoke 9160.

One embodiment of the locking mechanism 9164 is depicted in Figures 15-15g. However, as can be appreciated, alternative means may be used to lock or unlock the cover 9104. [ In this embodiment, the lid 9104 may further include a catch 9170 extending from the lid 9104. The locking mechanism 9164 is configured to releasably secure the lid 9104 in the closed position . In some embodiments, the locking mechanism 9164 includes a latch 9171 (latch) that is removably connected to the frame 9102. When engaged, the latch 9171 holds the latch 9170 in place and prevents the lid 9104 from being stretched. In other embodiments, the alignment and actuation of latch 9171 and latch 9170 in the context of each other is reversed. In such embodiments, latch 9171 is disposed on lid 9104 and latch 9170 is removably connected to frame 9102. [ In some embodiments, the latch 9171 is biased to the first latch position, and the latch 9171 can be engaged in the first latch position. The spring may be used to bias the latch 9171 to the first latch position. However, in alternate embodiments, other deflection mechanisms may be applied.

When latch 9171 is released, lid 9104 is free to collapse into an open position. In some embodiments, the latch 9171 may be moved from the first latch position to the second latch position by a trigger 9173 (trigger). When in the second latch position, the latch 9171 can be disassembled. Some embodiments may include one trigger 9173 when the latch 9171 is in engagement with the latch 9170 and is in the first latched position holding the lid 9104 in the closed position. However, other embodiments may include multiple triggers 9173. Figures 15-15g depict an embodiment with two triggers 9173. When the triggers 9173 are activated, the biasing element 9172 is compressed and the latch 9170 can be released in the latch 9171, allowing the lid 9104 to expand.

In the embodiment depicted in Figures 15-15c, the trigger 9173 may be activated by a release mechanism 9174 configured to interact with the locking mechanism 9164. [ The position of the locking mechanism 9164 may be changed in other embodiments. And the interaction between the locking mechanism 9164 and the disassembly mechanism may be different in the following embodiments. The release mechanism 9174 includes an upper operating element 9175 and a lower operating element 9176. [ In some embodiments, the upper actuating element 9175 is at least partially disposed in the upper portion 9107A of the connector assembly 9107 and the lower actuating element 9176 is disposed in the lower portion 9107B of the connector assembly 9107 at least partially And is partially disposed. The connector assembly 9107 can be configured such that the upper actuating element 9175 and the lower actuating element 9176 are not interfered with the pivoting function by the joint 9106. [

The upper actuating element 9175 may further include an upper edge 9178 and a lower edge 9179. [ In some embodiments, the upper actuating element 9175 may have a first position and a second position. In some embodiments, as depicted in Figure 15G, the upper actuating element 9175 can be switched between the first position and the second position by the button 9181. [ As can be appreciated, the buttons may be placed in different locations in other embodiments. In some embodiments, the button can be actuated by being pushed in a lateral or axial direction. In the first position, the upper edge 9178 protrudes beyond the upper portion 9107A of the connector assembly 9107. And, in the second position, the lower edge 9179 protrudes from the upper portion 9107A. In some embodiments, the deflecting element 9177 can deflect the upper edge 9178 and the lower extendable edge to a first position. The push-rod mechanism depicted in Figures 15-15c is in the first position. In some embodiments, the biasing element 9177 includes a spring. One such embodiment is depicted in Figures 15-15c. In some embodiments, the upper actuating element 9175 may include its spring to maintain its proper position without relying on the deflecting element 9177. [

In some embodiments, when pressure is applied to the upper edge 9178, the upper actuating element 9175 can be moved from the first position to the second position. The upper actuating element 9175 is capable of compressing the deflecting element 9177. This may cause the upper edge 9178 to enter into the upper assembly 9107A.
