Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.

The first embodiment is as follows:

referring to fig. 1 to 7, the present embodiment provides a replaceable cleaning head 2, which includes a housing 21 adapted to be detachably attached to a suction source 1; the housing 21 has a collection chamber 21c for collecting debris, a first opening 21a communicating with the suction source 1 to generate a negative pressure at a second opening 21b, a second opening 21b for taking in debris from the outside of the housing 21; and a cleaning sheet 22 detachably attached to the bottom wall of the housing 21;

wherein the first opening 21a and the second opening 21b are in fluid communication and a filter 23 is arranged at the first opening 21a for separating debris from the fluid, and the collecting chamber 21c is arranged with a debris inlet for the debris to enter.

As shown in fig. 1, the suction source 1 includes a suction pump built therein, i.e., a fan, which when rotated at a high speed may create a negative pressure at the second opening 21b of the cleaner head 2, by which debris is sucked into the cleaner head 2. The lower part of the suction source 1 has a detachable interface with the cleaner head 2, typically a snap-on interface to facilitate connection and disconnection of the two. The detachable connection structure between the suction source 1 and the cleaning head 2 is beneficial to realizing various cleaning functions. In addition, based on the characteristics, the cleaning head 2 in the embodiment can be used for reforming the existing vacuum cleaner, and only the cleaning head 2 in the embodiment is used for replacing the original rolling brush component of the vacuum cleaner.

As shown in fig. 2 and 3, the cleaning sheet 22 is detachably attached to the bottom of the housing 21, and specifically, the cleaning sheet 22 is adhered to the bottom of the housing 21 by the hook and loop fastener 21d. The hook and loop fastener 21d is also a hook and loop fastener, which is a common detachable connecting component. The cleaning sheet 22 is detachably attached to the housing 21, and the cleaning sheet 22 can be detached for cleaning after being soiled, which can drastically reduce the use cost as compared with the disposable cleaning head 2.

As shown in fig. 5, a first opening 21a is disposed on the front wall of the housing 21, a second opening 21b is disposed on the top of the housing 21, and a curved flow path is configured between the first opening 21a and the second opening 21b. Specifically, the first opening 21a is directed upward and the second opening 21b is directed forward, and specifically in this embodiment, the second opening 21b is directed forward and downward to facilitate collection of debris. The fluid enters from the second opening 21b by the suction source 1 and then flows out from the first opening 21a, so that the flow passage between the two is a curved flow passage. The provision of the flow path in a curved configuration facilitates separation of debris from the fluid. In addition, the efficiency of collecting the debris can be improved by opening the first opening 21a on the front wall of the housing 21. The collection chamber 21c is disposed at a position further to the rear side than the curved flow path in the housing 21, and the collection chamber 21c is configured such that, when the suction source 1 is operated, convection air capable of stirring debris is not generated in the collection chamber 21c. When the suction source 1 is in operation, only the debris inlet of the collection chamber 21c communicates with the first opening 21a. It is favorable to collect the separated debris and can prevent the fluid in the curved flow passage from stirring the debris in the collection chamber 21c and further blocking the filter 23 when flowing, so that the wind pressure at the second outlet is reduced and the noise of the whole machine is increased. Specifically, the collection chamber 21c is in a semi-closed state when the suction source 1 is in operation, and only the debris inlet is open, so that no air convection is formed in the collection chamber 21c, and the absence of air convection prevents debris in the collection chamber 21c from being agitated.

For convenience of description of the technical solution of the present invention, the relative positional relationships between the front and back, the top and bottom, and the like in the present embodiment are all referred to the orientations identified in fig. 1 and 5.

As shown in fig. 6, at least one fastening tape 21d, specifically two, three, or four fastening tapes, is fixedly disposed on the outer side of the bottom wall of the housing 21, and in the present embodiment, four fastening tapes 21d are provided. The cleaning sheet 22 and the hook and loop fastener 21d are detachably bonded to attach the bottom wall. In order to facilitate scrubbing the ground, the outer side of the bottom wall of the shell 21 is provided with a plane.

Referring again to fig. 4 and 5, the housing 21 has an upwardly extending annular wall defining the first opening 21a at the top of the housing 21, which is a standing wall. The top surface of the annular wall forms a sealing surface 21f which sealing surface 21f cooperates with a seal to form a seal between the housing 21 and the suction source 1, where the sealing arrangement is arranged to reduce the suction underpressure at the second outlet in order to prevent air leakage. Specifically, the sealing member may be a rubber member or a sealing felt or the like. The annular wall is arranged in the front region of the housing 21 and extends upward from the top wall of the housing 21. The front region refers to a region of the housing 21 located forward, but this does not limit a portion of the annular wall to be located rearward of the midline of the housing 21, as long as a majority of the first opening 21a formed by the annular wall is located in the front region of the housing 21.

As shown in fig. 2 and 3, the filter 23 is fixed at the first opening 21a, that is, the filter 23 is non-detachably mounted on the annular wall, and the fixing may be screw fixing, riveting fixing, or ultrasonic welding fixing, or may be integral injection molding fixing. The filter 23 is a water washable filter 23 made of non-woven fabric or nylon net, in this embodiment, the filter 23 is a sheet, and the filter 23 may be made of other materials, such as cotton. In another embodiment, the filter 23 is detachably engaged with the first opening 21a, and the detachable engagement may be that the filter 23 is clamped and fixed by the housing 21 and the base of the suction source 1, or a detachable fixing structure, such as a snap-in structure, may be adopted.

As shown in fig. 5, the collection chamber 21c and the first opening 21a are arranged in the transverse direction, and the second opening 21b is arranged in the longitudinal direction. This further facilitates the separation of debris from the fluid and its settling in the collection chamber 21c. Furthermore, the lower edge of the first opening 21a is slightly higher than the inner side surface of the bottom wall of the collection chamber 21c, or flush. In the present embodiment, the lateral direction refers to the horizontal direction, and the longitudinal direction refers to the vertical direction.

As shown in fig. 6, at least portions of the front wall of the housing 21 on both sides of the second opening 21b are configured as inclined surfaces 21g adapted to guide the debris into the second opening 21b. The inclined surfaces 21g are respectively located outside the front wall of the housing 21, extend outward from the edges of the second opening 21b, and are formed only on a part of the outer side surface of the front wall of the housing 21, rather than occupying the entire outer side surface of the front wall of the housing 21. This reduces the difficulty of manufacture and facilitates the collection of debris.

As shown in fig. 3, 5 and 7, the housing 21 is provided with a debris outlet for pouring debris out of the collection chamber 21c, and the debris outlet is provided with a cover plate 21e for closing the debris outlet when the suction source 1 is in operation. The debris outlet is formed in the rear wall of the housing 21 and the cover plate 21e is pivotally attached to the housing 21. Specifically, two sides of the lower portion of the cover plate 21e are respectively provided with a pivot, and the corresponding position of the housing 21 is provided with a pivot hole, and the pivot is inserted into the pivot hole to realize the pivot connection of the cover plate 21e. A snap-fit connection is provided between the upper part of the cover 21e and the housing 21, the cover 21e and the housing 21 snap-fitting to close the debris outlet when the suction source 1 is in operation. When the suction source 1 is deactivated, the catch may be disengaged and the cover 21e flipped open the debris outlet to dump the collected debris.

The utility model also provides a surface cleaning equipment, including suction source 1 and cleaning head 2, cleaning head 2 is above-mentioned but substitution cleaning head 2. The suction source 1 is the main structure of the vacuum cleaner.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention.
