Referring to fig. 1-3, fig. 1 is a schematic structural view of a surface cleaning apparatus according to an embodiment of the present invention. FIG. 2 is a schematic diagram of the structure of the cleaning head connected to the connection head through the hose according to one embodiment. Fig. 3 is a sectional view taken along a-a in fig. 2. Fig. 1 discloses a surface cleaning apparatus 1 comprising a main unit 2 and a cleaning head 3, the main unit 2 and the cleaning head 3 being fluidly connectable via a hose 21 (see also fig. 2 or 3) or an extension rod or the like, although the cleaning head 3 may also be directly connectable to the main unit 2. A connection head 4 is provided between the cleaning head 3 and the main body 2, and referring to fig. 4-7, fig. 4 is an enlarged schematic view of the structure of the area B. Fig. 5 is an exploded view of the connecting head according to an embodiment. FIG. 6 is a diagram of a connection assembly according to an embodiment.

Connector 4 includes shell 51 and sets up coupling assembling 5 in shell 51, is provided with the damper between shell 51 and the coupling assembling 5, simultaneously, still is provided with the hasp on the shell 51 to make things convenient for connector 4 and host computer 2 detachable to be connected. The connector 4 is further provided with pins 92 for electrical conduction, the pins 92 being electrically connected to electrical components located on the main body 2. The cleaning head 3 is provided with a switch which can control the start and stop of power equipment (a water pump, a heater or a steam generator and the like) in the surface cleaning equipment 1.

With continued reference to fig. 4-9, fig. 8 is an exploded view of the connection assembly at another angle. Fig. 9 is a sectional view of the connection assembly in the direction of steam flow. The connecting assembly 5 includes a first connecting member 7 and a second connecting member 8, both of which are integrally formed and formed by injection molding, in a specific embodiment, the first connecting member 7 and the second connecting member 8 are made of polyamide 66+30% glass fiber, of course, in other embodiments, the first connecting member 7 and the second connecting member 8 may also be made of other materials and molded into an integral structure, and the first connecting member 7 and the second connecting member 8 may be fixedly connected by bolts. In other embodiments, the first connecting member 7 and the second connecting member 8 may be connected by gluing or ultrasonic welding.

Referring to fig. 4 to 9, the first connecting member 7 has a first steam passage 71 defined therein; the first connection 7 comprises an inlet end 72 and an outlet end 73 in the fluid flow direction of the first steam channel 71. The air outlet end 73 of the first connecting member 7 may be connected to the steam hose 21. The second connecting member 8 is disposed at the air inlet of the air outlet 73, and the second connecting member 8 includes a connecting plate 82 for sealing the air inlet and a second steam passage 81 connected to the connecting plate 82. The connecting plate 82 may have a plate-like structure, and may have other shapes, which mainly serve to seal the air inlet end 72 of the first connecting member 7, and in other embodiments, the connecting plate 82 may communicate with the first and second steam passages 81. Referring to fig. 7 and 8, the second steam passage 81 is in fluid communication with the first steam passage 71 after passing through the connection plate 82. The second steam passage 81 is detachably fluidly connected to the steam passage of the main unit 2, and in order to fit the connection head 4 to the main unit 2, the cross-sectional area of the first steam passage 71 perpendicular to the fluid flow direction is larger than the radius of the second steam passage 81. The outer circumference of the second steam passage 81 is provided with at least one sealing ring to seal between the first steam passage 71 and the steam passage of the main unit 2.

Referring to fig. 4, to ensure versatility of the connection assembly 5, the axis of the second steam channel 81 is offset from the axis of the first steam channel 71 such that the second steam channel 81 clears the suction opening of the surface cleaning apparatus 1. Referring to fig. 4, in one embodiment, the axis of the first steam channel 71 is located substantially at the center of the connection head 4, and the second steam channel 81 is disposed at a position away from the center of the connection plate 82. That is, the axis of the second steam passage 81 is as far away from the axis of the first steam passage 71 as possible to ensure that the suction area of the suction port on the main unit is as large as possible with a relatively small overall radius of the connection head 4.

Referring to fig. 9, in one embodiment, the axis of the second steam passage 81 does not pass through the first steam passage 71, and specifically, the axis of the second steam passage 81 is located below the first steam passage 71. In order to avoid energy loss caused by the fact that the steam jetting port of the second steam channel 81 directly blows to the wall surface, a transition steam channel 9 is arranged between the first steam channel 71 and the second steam channel 81, and the arrangement of the transition steam channel 9 can reduce the energy loss of steam flowing from the smaller second steam channel 81 to the larger first steam channel 71. Further, in order to reduce energy loss as much as possible, the cross-sectional area of the first steam passage 71 in the direction perpendicular to the fluid flow is smaller than the cross-sectional area of the transition steam passage 9. Thus, the steam enters the transition steam channel 9 from the second steam channel 81 to the first steam channel 71, and plays a role of buffering.

Referring to fig. 7, in order to ensure the sealing property between the first connector 7 and the second connector 8, a sealing ring 6 is disposed between the first connector 7 and the second connector 8, and the sealing ring 6 is disposed at the outer circumference of the transition steam passage 9. Meanwhile, in order to ensure that the second steam passage 81 is as close as possible to the edge of the connection plate 82, a packing 6 is provided to the outer circumference of the transition steam passage 9 so that the sectional area of the transition steam passage 9 becomes as large as possible.

Referring to fig. 7, when the first connector 7 and the second connector 8 are fastened by bolts, the bolt columns 91 are located in the transition steam passage 9, and thus the sectional area of the transition steam passage 9 can be increased, and the second steam passage 81 can be ensured to be as close to the edge of the connecting plate 82 as possible.

With continued reference to fig. 5, in order to make reasonable use of space, pins 92 for electrical conduction are also provided within the housing 51, at least some of the pins 92 being provided below the transitional steam channel 9.

While the embodiments of the invention have been described above, it is not intended to be limited to the embodiments shown, and described, but rather to be accorded the widest scope consistent with the principles and novel features herein disclosed, and to such extent as may be readily modified by those skilled in the art, and to such extent as is not limited by the specific details shown and described herein without departing from the general concepts defined by the claims and their equivalents.
