Background

Currently, in order to more thoroughly clean the cleaning surface, conventional cleaning methods include sweeping, vacuuming and wiping. Among them, wiping, commonly known as mopping, is the repeated rubbing of a wet or dry wipe, such as a fabric, against a surface to be cleaned to more thoroughly remove dust, adherent stains, water stains, etc. from the surface to be cleaned.

When the traditional mop is used, the wiping head needs to be washed and drained for multiple times to obtain an ideal using state, in order to simplify the floor mopping operation, the steam mop is produced by transporting steam to the wiping head, steam is continuously generated by the steam generating device, then the steam flow is conveyed to the wiping head, the steam is used for maintaining the humidity and the temperature of the wiping material on the wiping head, the ideal state of the wiping head is kept, and therefore the cleaning surface is effectively cleaned. And the purposes of disinfecting and sterilizing the cleaning surface are realized through the high temperature of the steam.

In the product development process of the steam mop conducted by the inventor, the steam mop product sold in the market is found to have the following problems: during use, wipes such as cleaning pads provided on the wiping head do not wet evenly well with the steam flow, which is not evenly distributed over the cleaning pad. Therefore, there is a need to analyze the existing products, determine the cause and the solving means of the problems.

The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.

As a preferred implementation manner, the fluid inlet is provided with a flow equalizing portion, and the flow equalizing portion includes a flow equalizing cavity communicated with the fluid inlet and a plurality of flow equalizing ports communicated with the flow equalizing cavity and arranged in the circumferential direction of the fluid inlet;

a plurality of guide support ribs are arranged in the fluid cavity, and at least part of the fluid cavity is divided into a plurality of flow guide channels by the guide support ribs; each flow guide channel is communicated with at least one flow distribution groove.

Preferably, at least one of the guide support ribs is formed with a notch or a through hole communicating with the flow guide channel.

The guide support rib is provided with a notch or a through hole which is communicated with the flow guide channels positioned at two sides of the guide support rib.

As a preferred realization, at least part of the flow equalizing ports are arranged in an equispaced manner within a first angular range of the circumference of the fluid inlet.

As a preferred implementation, an inclined surface extending to the bottom surface of the support plate is formed at an edge of the fluid chamber within a second angular range of a circumference of the fluid inlet; the second angular range is within the first angular range.

As a preferred implementation manner, a supporting protrusion which is flush with the bottom surface of the supporting plate or protrudes out of the bottom surface of the supporting plate is arranged in the shunting groove; or

And a support protrusion which is flush with or protrudes out of the bottom surface of the support plate is arranged adjacent to the diversion trench.

As a preferred realization, the support plate has a rearward end located at one side of the fluid chamber; a forward end on the other side of the fluid chamber opposite the rearward end; a left side and a right side between the rearward end and the forward end; the fluid cavity is located between the left side portion and the right side portion;

wherein the length of the rearward end is greater than the length of the forward end; the splitter box is arranged on the left side part and the right side part.

Preferably, the extension direction of each splitter box is consistent with the direction of the backward end pointing to the forward end.

As a preferred realization, the depth of the fluid chamber ranges from 3mm to 8 mm.

The steam mop is characterized by comprising a steam generation unit and the wiping head of the steam mop in each implementation mode, wherein the wiping head is connected with the steam generation unit.

The inventors have found that the main reason why the cleaning pad is not uniformly wetted by the steam and then applied to the cleaning surface after passing through the cleaning pad is that the steam flowing space between the supporting plate and the cleaning pad is relatively closed, which is not conducive to the steam flowing to the cleaning pad, and tends to form "dead space" in the flow, so that some cleaning pads are always kept in a dry state to participate in cleaning, which affects the cleaning effect, and the dry friction also reduces the service life of the cleaning pad. Furthermore, the support plate and the cleaning pad are closely attached to each other at the periphery of the fluid chamber providing the vapor circulation space, so that the vapor is difficult to circulate to the position, and most of the cleaning pad closely attached to the support plate is in a drier state.

In view of the above-mentioned findings, the inventor proposes the foregoing implementation manner, in which the steam outlet from the fluid chamber is provided through the diversion channel, the air tightness of the steam communication environment between the cleaning pad and the support plate is properly weakened, and after part of the steam is guided to flow through the fluid chamber and then flow out from the diversion channel, the small amount of the overflow is beneficial to the steam flow to flow through most of the fluid chamber, so as to sufficiently contact and infiltrate with each part of the cleaning pad and then act on the cleaning surface, thereby improving the use condition of the cleaning pad and allowing more cleaning pads to be infiltrated. The uniform distribution of the steam to the pad also prevents the steam from concentrating and condensing water from accumulating on a localized area of the pad, and prolongs the drying latency of the floor surface after mopping. Meanwhile, the local overhigh temperature can be avoided to a certain extent, and certain special cleaning surfaces, such as a waxing layer of a floor, can be damaged.

Meanwhile, the steam flow can reach the edge of the fluid cavity through the splitter box, so that the cleaning pad tightly attached to the supported plate can be fully soaked, and the occurrence of dry friction is reduced.

In addition, the dissipated steam can slightly soak the uncleaned cleaning surface at the periphery of the wiping head at a high temperature in advance, so that a certain pre-cleaning effect is achieved, and the wiping head can more easily wipe the cleaning surface.

As shown in fig. 1, the steam mop includes a steam generation unit 1200 and a wiping head 1100 connected to the steam generation unit 1200. The connection of the two comprises structural connection and communication of a steam flow path. In most implementations, the connection of the steam generation unit 1200 to the wiping head 1100 is detachable.

Various implementations of the wiping head in the steam mop will be described in detail below.

In one implementation, and with reference to fig. 2, a wiping head of a steam mop includes: a cleaning pad 1102 and a support plate 1101 for supporting the cleaning pad 1102, wherein the cleaning pad 1102 is formed of a fabric having a certain hydrophilicity and a certain air permeability, such as a cotton fabric, a chemical fiber fabric, a wool fabric or a mixed fabric of a plurality of fibers. The bottom surface of the supporting plate 1101 is provided with a connecting member 1114, such as a hook and loop fastener capable of adhering the cleaning pad 1102, and when the cleaning pad is pressed to the surface of the connecting member 1114, the cleaning pad is adhered to the connecting member, thereby being firmly fixed and supported by the supporting plate 1101. When the cleaning pad needs to be removed, the cleaning pad can be pulled off by force. In addition, the cleaning pad can be secured to the support plate by other fastening means so as to be supported, primarily by the support, to spread the cleaning pad flat and enable the cleaning surface with which it has to be wiped to wipe the cleaning surface. Referring to fig. 13, a connector 91110 can also be provided on the support plate, and the cleaning pad can be provided with a connector or a connecting string matching 91110, and connected together by snapping or twisting. In another embodiment not shown in the drawings, a holding frame may be provided on the support plate to hold and fix the cleaning pad in the circumferential direction of the cleaning pad.

In addition, referring to fig. 2, the bottom surface of the support plate is formed with a concave fluid chamber 1111, the cleaning pad 1102 can cover the fluid chamber 1111 when being attached to the bottom surface of the support plate, and one of the functions of the fluid chamber 1111 is to provide a space for steam to flow between the support plate and the cleaning pad.

The support plate is formed with a fluid inlet port 1112 communicating with the fluid chamber 1111 as a passage for steam generated from the steam generating unit to enter the fluid chamber along the piping. Wherein, at the bottom of the supporting plate, a shunting groove 1113 for communicating the fluid chamber 1111 and the outside of the supporting plate is arranged around the fluid chamber 1111.

The outlet of the steam from the fluid chamber 1111 is provided by the splitter 1113, and a small part of the steam is allowed to be discharged from the outlet, which is beneficial to guiding the steam to be uniformly distributed in the fluid chamber 1111, and in a relatively closed space, after the steam flows into the relatively closed space, the steam is difficult to be naturally and uniformly distributed under the driving of positive pressure, and in addition, the steam flows into the fluid chamber from the inlet, and then impacts and flows back after flowing to the edge of the fluid chamber, so that turbulence is caused, and the uniform distribution of the steam is influenced. By providing the steam outlet, the steam can smoothly spread to the edge of the fluid cavity, and the flowing dead angle is reduced. It is apparent that the uniform flow of steam through the fluid chamber is beneficial in improving the cleaning efficiency of the wiping head on the cleaning surface. It should be noted that the splitter boxes indicate that only a small portion of the steam flow will escape from the flow chamber, thereby achieving the objective of providing overflow outlets to improve the uniformity of the steam flow. It also improves the vapor infiltration of the cleaning pad around the fluid chamber to reduce the occurrence of dry rub.

As a preferable mode for matching with the foregoing implementation, referring to fig. 3 and 4, on the support plate 2101, the fluid inlet 2112 is provided with a flow equalizing portion 21122, the flow equalizing portion 21122 includes a flow equalizing chamber communicated with the fluid inlet 2112, and a plurality of flow equalizing ports 21123 communicated with the flow equalizing chamber 2111 and arranged in the circumferential direction of the fluid inlet;

in addition, a plurality of guide support ribs 2115 are arranged in the fluid cavity 2111, and at least part of the fluid cavity 2111 is divided into a plurality of guide channels 21111 by the guide support ribs 2115; each flow guide passage 21111 communicates with at least one diverter channel 2113. The height of the guide support ribs will generally correspond to the depth of the fluid chamber, i.e., the guide support ribs will support the cleaning pad as it covers the fluid chamber, thereby preventing the cleaning pad from sinking into the fluid chamber and no longer maintaining a flat condition.

The flow guide channel limited by the guide support ribs allows steam to flow to the splitter box along a plurality of paths after flowing out through the flow equalizing port, further increases the uniformity of the distribution of the steam flowing in the fluid cavity, and also allows the steam to flow to the peripheral side from the central opening through a relatively determined flow direction. Not only facilitates sufficient vapor flow through the cleaning pad to cover portions of the fluid chamber, but also ensures a substantially uniform vapor flow throughout the cleaning pad, both as a result of direct heating and cleaning of the cleaning surface by the vapor passing through the cleaning pad, and as a result of more uniform wetting of the cleaning pad by the vapor.

Referring to fig. 7 and 8, a notch 51151 communicating with the guide passage is formed in each guide support rib 5115. In other optional implementations, some of the guiding support bars may be formed with notches, and other guiding support bars do not need to be formed with notches. In addition, in other alternative implementations, the structure of the notch may be equivalently replaced by a through hole.

Adjacent guide channels can be used as downstream adjustment measures through the gaps of the guide support ribs or through being communicated, and if the steam flow in each guide channel is uneven, the flow difference can be balanced through the gaps or the through holes.

In the embodiments shown in fig. 3, 7, 9 and 10, the flow equalizing ports are uniformly arranged in the circumferential direction of the fluid inlet, and are relatively uniformly distributed in all directions after the steam enters the steam cavity. According to different use scenes, the flow equalizing ports may be uniformly distributed in a certain range rather than the whole circumferential range, for example, the uniformly distributed flow equalizing ports are arranged in the front half part close to the front side, and the uniformly distributed flow equalizing ports are not required in the rear half part. And the density degree of the flow equalizing openings arranged on the front half part and the rear half part is different. For example, as shown in fig. 13, the flow equalizing ports are provided in plural on the front half side, and the number of the flow equalizing ports arranged on the rear half side is smaller than that on the front half side, which is adjusted to fit a specific shape of the wiping head in the implementation shown in fig. 13.

As shown in fig. 13, the flow equalizing port opened at the front side of the flow equalizing unit 91122 is arranged in a first angle range α in the circumferential direction of the fluid inlet, and in a second angle range β in the circumferential direction of the fluid inlet, an inclined surface 91113 extending to the bottom surface of the support plate is formed at the edge of the fluid chamber; and the second angle range β is within the first angle range α.

The inclined surface acts to gradually reduce the flow area of the flow guide channel to prevent excessive steam flow from exiting the outlet and to direct a substantial portion of the steam through the inclined surface to soak into the cleaning pad. As the flow is reduced along with the distance from the air inlet, the flow rate can be improved by reducing the section, and the steam infiltration is more facilitated. In the figure, the inclined surface is arranged in the range of the front half side with the closely distributed flow equalizing ports, which is a requirement of matching use, the wiping head is shown to be roughly triangular, and is mainly used for cleaning corners inconvenient for square frame cleaning, and the cleaning pad on the front half side of the wiping head participates in wiping more frequently and needs to be penetrated and soaked by more and more uniform steam.

The inclined surface is further formed in the fluid chamber according to the shape of the support plate in fig. 5 with reference to fig. 5 and 6; fig. 6 shows an implementation of the inclined surface 41113 engaging with the supporting rib 4115.

On the basis of the various implementation modes, a supporting bulge which is flush with the bottom surface of the supporting plate or protrudes out of the bottom surface of the supporting plate is arranged in the shunting groove; and a support protrusion which is flush with or protrudes out of the bottom surface of the support plate is arranged adjacent to the diversion channel. The steam that the supporting bulge flows out the splitter box flows equally once more or the direction to in the use, the supporting bulge can also let clean pad and clean surface laminating more inseparabler. As shown in fig. 12 and 13, the supporting protrusions are distributed in the splitter box in a single row. As a different implementation, as shown in fig. 9, the support protrusions 6116 may also be distributed in two rows in the diversion trench 6113. Furthermore, as an alternative, the support protrusions 7116 may also be staggered low within the diverter slots 7113, as shown in fig. 10.

Further, as a modification or preferable adjustment of the solution disclosed in the foregoing various implementations, the support plate has a rearward end 8118 located at a side of the fluid chamber; a forward end 8117 on the other side of the fluid chamber opposite the rearward end 8118; left and right sides 8119 between the rearward and forward ends 8118, 8117; the fluid cavity is positioned between the left side part and the right side part; wherein the length of the backward end is greater than the length of the forward end; the diversion trench 8113 is located on the left side and the right side.

That is, the support plate of the mop head will have a narrower forward end than the rearward end to support the forward end of the mop head extending into some narrow, compact space, such as the corners of a house, wall turns, etc., for targeted cleaning. The left and right side portions will form an angle, which may range, for example, between 45 ° and 135 °.

Referring to fig. 12, in a preferred implementation, the support plate of the wiping head is substantially triangular and is mainly used for wiping the cleaning surface at the narrow space, and the diversion channels are arranged at the left side and the right side, so that the leaked steam can slightly play a role of infiltrating the ground in advance and fully utilize the steam. The cleaning pad is shaped to substantially match the support plate. Three angles of the triangle form a fillet, and the transition and the guide can be adaptively carried out on the steering in the cleaning process, so that the collision is reduced.

The outline of the fluid cavity formed by the corresponding triangular wiping head is also approximately triangular or trapezoidal, the fluid inlet is arranged to be approximately positioned in the center of the triangle or the midline of the triangle passes through the fluid inlet, and steam flows to the two sides of the triangular wiping head through paths which are approximately symmetrical along the midline of the triangle after entering the fluid cavity, so that the steam flow in the fluid cavity is uniformly distributed in an ideal mode.

In addition, the rear side of the fluid chamber is recessed or compressed forwards, and particularly, the bottom of the wiping head is partially thickened around the wall of the fluid chamber, so that the triangular wiping head is not required to split steam from the rear side to flow out when in use, and accordingly, the steam flow using amount of the front end and the two sides is higher, and the arrangement is more reasonable and meets the use habit.

As shown, the extension direction of each splitter box is approximately consistent with the direction of the backward end pointing to the forward end. Therefore, the steam flows to the front side of the wiping head through the guiding of the splitter box, and the operation habit of wiping operation is relatively met. In the illustrated construction, the vapor is distributed generally uniformly throughout the fluid chamber in the direction indicated by the arrows, particularly the front half, and then flows relatively uniformly to the side-forward direction of the wiping head, which portion of the vapor will prematurely wet the cleaning surface to be wiped by the wiping head during wiping. When the corner is cleaned, the edge of the corner can be sufficiently cleaned.

As a further preferred arrangement of the various implementations described above, the depth of the fluid cavity ranges from 3mm to 8 mm.
