Referring to fig. 2, the cleaning head 100 includes a housing 1, a driving member 2 disposed in the housing 1, and a cleaning assembly 3 rotatably coupled to the housing 1 for cleaning a surface to be cleaned. Wherein, casing 1 includes body 11 and the window upper cover 12 of being connected with body 11, and forms accommodation space 13 between window upper cover 12 and the body 11, and clean subassembly 3 rotates and sets up in accommodation space 13. The cleaning assembly 3 has a contact side which is in contact with the surface to be cleaned. When the user uses the cleaning head 100, the driving member 2 is directly turned on to drive the cleaning member to move on the surface to be cleaned so as to clean the surface to be cleaned.

Referring to FIG. 2, to improve the cleaning efficiency of the surface to be cleaned, the cleaning head 100 also includes a fluid delivery assembly 4. Wherein the fluid delivery assembly 4 has at least one output port 41, the fluid delivery assembly 4 delivers the cleaning medium to the target location through the at least one output port 41. In particular, the at least one outlet 41 of the fluid delivery assembly 4 may deliver the cleaning medium to the cleaning assembly 3 and also to the surface to be cleaned. When the cleaning medium is conveyed to the cleaning assembly 3, and the surface to be cleaned has stubborn stains, the cleaning assembly 3 cannot effectively clean the surface to be cleaned with the stubborn stains. When the cleaning medium is conveyed to the surface to be cleaned, the cleaning medium cannot obviously clean stubborn stains and sterilize the surface to be cleaned.

In order to solve the above problem, in the present embodiment, the at least one output port 41 of the fluid delivery assembly 4 is disposed between the plane of the central axis of the cleaning assembly 3 and the plane of the contact side. In the embodiment of the present specification, the plane of the central axis of the cleaning assembly 3 is parallel to the plane of the contact side.

In particular, at least part of the at least one output opening 41 is arranged towards the cleaning assembly 3 such that the fluid delivery assembly 4 delivers at least part of the cleaning medium to the cleaning assembly through the at least one output opening 41, such that part of the cleaning medium output from the output opening 41 acts on the cleaning assembly 3 to wet, clean, sterilize, etc. the cleaning assembly 3.

In order to be able to deliver the water in the tank to the outlet 41, the fluid delivery assembly 4 further comprises a water pump 42 communicating with said outlet 41. The water pump 42 is used to pump water at normal temperature from the water tank to the output port 41 and from the output port 41 to the cleaning assembly 3 and the surface to be cleaned when the cleaning head 100 is cleaning the surface to be cleaned.

To further increase the cleaning efficiency of the cleaning assembly 3, the fluid delivery assembly 4 further includes a heating member 43 in communication with the output port 41. One end of the heating member 43 is communicated with the water tank, and the other end of the heating member 43 is communicated with the output port 41. So that the water at normal temperature in the water tank can be heated to the hot water at the preset temperature by the heating element 43 or the water at normal temperature in the water tank is converted into steam to be output from the output port 41, or the water pump 42 can directly output the water at normal temperature in the water tank from the output port 41. When the hot water or steam heated by the heating element 43 is output, the cleaning effect of the surface to be cleaned can be improved, and the higher temperature can realize the sterilization effect on the surface to be cleaned.

The fluid delivery assembly 4 further comprises a guide in communication with the at least one output port 41 for delivering the cleaning medium to the cleaning assembly 3 and the surface to be cleaned through the output port 41. Therefore, the cleaning medium output from the output port 41 partially acts on the cleaning component 3 and partially acts on the surface to be cleaned, so that the cleaning medium acting on the surface to be cleaned can dissolve stubborn stains on the surface to be cleaned in advance, and then the surface to be cleaned is cleaned through the soaked cleaning component 3, and the cleaning efficiency is improved.

In one embodiment, referring to fig. 2 and 3 and fig. 4, the fluid delivery assembly 4 further includes a water trap 44 disposed at the front end of the cleaning assembly 3. The water separator 44 is connected to the outlet 41 as the guide. The water separator 44 has at least one nozzle 441 and a water inlet 442. Wherein the output port 41 is formed on the nozzle 441, and the water inlet 442 is communicated with the water pump 42 or the heating member 43, so that the cleaning medium in the water tank can enter into the water separator 44 through the water inlet 442 and be output onto the cleaning assembly 3 and the surface to be cleaned through the output port 41 on the nozzle 441. It should be noted that in the present embodiment, the included angle between the plane where the output port 41 is located and the plane where the contact side is located is greater than 0 degree and smaller than 80 degrees, and is preferably 0 to 50 degrees, so that the cleaning medium output by the output port 41 can partially act on the surface to be cleaned and partially act on the cleaning assembly 3. In this embodiment, the heating member 43 is disposed within the cleaning head 100.

Specifically, the water inlet 442 is communicated with the water pump 42 through the first delivery pipe 46 and the heating member 43 through the second delivery pipe 47, respectively. More specifically, the fluid delivery assembly 4 further includes a valve body (not shown) through which the water inlet 442 can be selectively communicated with the water pump 42 through the first delivery conduit 46 or with the heating member 43 through the second delivery conduit 47. When the water inlet 442 is communicated with the water pump 42 through the first conveying pipeline 46, the water pump 42 can pump the normal temperature water in the water tank into the water separator 44 through the water inlet 442, and convey the normal temperature water to the cleaning assembly 3 and the surface to be cleaned through the output port 41, so as to clean the surface to be cleaned after the cleaning assembly 3 is soaked. When the water inlet 442 is communicated with the heating member 43 through the second conveying pipeline 47, hot water heated to a preset temperature by the heating member 43 or steam formed by the heating member 43 enters the water separator 44 through the second conveying pipeline 47 and the water inlet 442, and then the hot water or the steam is conveyed to the cleaning component 3 and a surface to be cleaned through the outlet 41 communicated with the water separator 44, so that the cleaning equipment can convey normal-temperature water or the hot water or the steam to the contact side of the cleaning component 3 through only arranging one water separator 44, the structure is simple, and the cleaning efficiency is high.

Referring to fig. 3, diverter 44 also includes a delivery line 443, which delivery line 443 is used to communicate inlet 442 with outlet 41. In this embodiment, the plurality of output ports 41 are formed on the nozzle 441 so as to be uniformly distributed along the axial length direction of the cleaning assembly 3. The water diverter 44 thus comprises a plurality of delivery lines 443, and the length of each delivery line 443 from the inlet 442 to each outlet 41 is the same, so that the same path is followed by the delivery lines 443 through which the cleaning medium flows, thereby ensuring that the amount of cleaning medium delivered to the outlet 41 through each delivery line 443 of the same length and the pressure to which it is subjected are the same. In this embodiment, the diameter of each transfer line 443 is also the same.

In this embodiment, the nozzle 441 is arranged to have a small inside and a small outsideA large tapered hole, which can use the tension of water so that water cannot naturally pass through the tapered hole without applying an external force. To prevent residual water in the water separator 44 from flowing out of the outlet 41 after the cleaning apparatus is stopped, thereby causing a residue on the floor. In this embodiment, the minimum cross-sectional area of the nozzle 441 is less than 0.5mm²The inner side is the side close to the cleaning component 3, and the outer side is the side far from the cleaning component 3.

In order to uniformly wet the roller brush at the output port 41, in this embodiment, the side of the output port 41 facing the cleaning assembly 3 is set to be a horizontally-dispersed shape with a slightly larger cross-sectional area, so that the cleaning medium output from the output port 41 can be dispersed in the axial length direction of the cleaning assembly 3 at a certain angle, and can better and uniformly wet the cleaning assembly 3.

The cleaner head 100 also includes a leather strap (not shown) connected to the diverter 44. One end of the leather strip is arranged below the nozzle 441 of the water separator 44, the other end of the leather strip is in interference connection with the cleaning component 3, and the leather strip is obliquely arranged from top to bottom from one end of the water separator 44 to one end of the cleaning component 3. The purpose of the leather strip is to prevent the normal temperature water or hot water output from the output port 41 from directly falling to the ground to form water stain residue when the cleaning medium is normal temperature water or hot water. Due to the leather strips, when the cleaning medium is steam, the steam cannot act on the ground to dissolve stubborn stains and achieve a high-temperature sterilization effect. In order to solve the problem, a through hole is formed at one side of the leather strip close to the water separator 44, and a boss is formed upwards at the through hole, so that when the cleaning medium is steam, part of the steam acts on the cleaning component 3, and part of the steam acts on the surface to be cleaned through the through hole. By arranging the leather strips, the steam output from the output port 41 can be diffused in the accommodating space 13, so that the cleaning component 3 can be soaked uniformly. Therefore, the steam can dissolve stubborn stains and sterilize on the surface to be cleaned at high temperature, the cleaning efficiency is improved, and meanwhile, the overflowed steam can also bring a good visual effect to a user. And when the cleaning medium is normal temperature water or hot water, because the leather strap that its self gravity and slope set up, normal temperature water or hot water can directly soak on pivoted cleaning component 3 along the leather strap surface, and can not overflow the boss and flow out from the through-hole to prevent that normal temperature water or hot water from flowing to ground and causing the ground residual water.

In another embodiment, referring to fig. 6 and 7, the fluid delivery assembly 4 includes a water jet 45, the water jet 45 serving as the guide and communicating with the output port 41. Specifically, the water nozzle 45 has a slope 451 forming the output port 41. The inclined surface 451 is inclined from top to bottom from a side close to the cleaning unit 3 to a side far from the cleaning unit 3 in a height direction of the cleaning head 100. It should be noted that the included angle between the plane where the output port 41 is located and the plane where the contact side is located is greater than 0 degree and smaller than 90 degrees, so that the output port 41 is disposed toward the lowest point of the contact side. When a user cleans a surface to be cleaned, the heating member 43 converts the water at normal temperature in the water tank into steam and delivers the lowest point of the contact side through the output port 41 on the inclined surface 451 of the water spray nozzle 45, thereby improving the cleaning efficiency of the surface to be cleaned. In other embodiments, the water spray nozzle 45 may not be provided, and the guide member may be disposed to be inclined toward the lowest point of the contact side, in which case the outlet 41 is formed on the guide member, so that the steam formed via the heating member 43 is delivered to the lowest point of the contact side through the guide member disposed to be inclined and the outlet 41 communicating with the guide member. Alternatively, the water spraying nozzle 45 may be directly communicated with the heating member 43 without providing a guide member, and the water spraying nozzle 45 may be disposed to be inclined toward the lowest point of the contact side, in which case the output port 41 is formed on the water spraying nozzle 45, and the steam formed by the heating member 43 is delivered to the lowest point of the contact side through the water spraying nozzle 45 and the output port 41, and the same effects as those described above may be achieved, and the structure of the pipeline for delivering the steam is not particularly limited, depending on the actual situation. It should be noted that, in the present embodiment, the lowest point of the contact side is the point of contact with the surface to be cleaned when the cleaning assembly 3 rotates. The heating member 43 may be disposed inside or outside the water tank as long as it can convert normal temperature water in the water tank into steam, and the position where the heating member 43 is disposed is not specifically limited herein, depending on the actual situation.

Referring to fig. 7, the fluid delivery assembly 4 further includes a delivery channel 452 in communication with the output port 41, the viewing window upper cover 12 has a receiving cavity 14, and the delivery pipe 443 is disposed in the receiving cavity 14, so that the receiving cavity 14 effectively protects the delivery pipe 443, and the delivery pipe 443 is prevented from being scratched when the cleaning head 100 is in operation.

In order to clean the sewage generated by the cleaning assembly 3 and the fluid delivery assembly 4 cooperating with the surface to be cleaned, in this embodiment, the cleaning head 100 further includes a suction assembly for sucking the sewage after the cleaning assembly 3 cleans the surface to be cleaned and the dirt particles on the surface to be cleaned into the sewage tank, so as to further clean the surface to be cleaned. Specifically, a dust inlet 111 is formed in the body 11 of the housing 1, and a suction duct 51 communicating the dust inlet 111 and the sump is formed in the cleaner head 100. It should be noted that the dust inlet 111 and the guide member are respectively disposed at both sides of the cleaning assembly 3. Specifically, the dust inlet 111 is arranged behind the lowest point of the contact side with the operation direction of the cleaning head 100 as the front, so that after stubborn stains on the surface to be cleaned are sufficiently dissolved and cleaned by matching the cleaning assembly 3 with steam, the suction motor sucks sewage stains or particles and the like into the sewage tank through the dust inlet 111, and further cleaning of the surface to be cleaned is realized. In addition, because the cleaning assembly 3 has a certain interference with the surface to be cleaned when cleaning the surface to be cleaned, and the dust inlet 111 and the guide member are respectively arranged at two sides of the cleaning assembly 3, the front of the cleaning assembly 3 can be isolated from the position of the dust inlet 111, that is, hot water or steam output from the output port 41 cannot be rapidly heated by the dust inlet 111, so that the influence of the suction force of the cleaning equipment on the heat of the cleaning assembly 3 is reduced to the maximum extent, the temperature of the cleaning assembly 3 is ensured to be between 40 and 100 ℃, and the temperature of the lowest point of the contact side is always kept above 40 ℃, thereby effectively improving the cleaning effect of the surface to be cleaned, and because the cleaning assembly 3 is always in a high-temperature state, the bacterial growth of the cleaning assembly 3 and the surface to be cleaned is effectively reduced.
