[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0039] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] refer to Figure 1-4 This application discloses a surface cleaning device 100, which includes a cleaning head 1. The surface cleaning device 100 can be any type of cleaning device such as a vacuum cleaner, floor scrubber, or sweeper. When the surface cleaning device 100 is a vacuum cleaner or floor scrubber, the cleaning head 1 can be detachably installed on the device. When the surface cleaning device 100 is a self-moving cleaning device such as a sweeper, the cleaning head 1 can be integrated into the sweeper.

[0042] refer to Figure 4-14The figure discloses a cleaning head 1, which includes a housing 11. The housing 11 can be the outer shell of a floor brush or the frame structure of a sweeper. The housing 11 is generally injection molded from plastic material, but it can also be made of other suitable materials, which will not be detailed here. The housing 11 defines a cavity, which can be connected to the suction channel of a surface cleaning device. A roller brush 12 is disposed inside the cavity, and the roller brush 12 is used to wipe the surface to be cleaned. The outer surface of the roller brush 12 can be made of non-woven fabric, absorbent material such as sponge, or it can have a structure such as leather strips or bristles on its outer surface. The roller brush 12 can be any form of roller brush 12 in the prior art, which will not be detailed here.

[0043] To enhance cleaning power, a scraper 14 is added to the cleaning head 1. Positioned in front of the roller brush 12 along the direction of travel, the scraper 14 is movable between a first position and a second position. The cleaning head 1 also includes a drive mechanism 14 for driving the scraper 14 to move between the first and second positions. The drive mechanism 14 drives the scraper 14 via a transmission mechanism 15. The scraper 14 is configured not to contact the surface to be cleaned in the first position, and is configured to contact the surface to be cleaned in the second position. Thus, when the cleaning head 1 moves forward (e.g....), Figure 6 (as shown in the direction), the scraper 14 is in the first position, which does not affect the cleaning effect. When the cleaning head 1 moves backward (as shown in the direction), the scraper 14 is in the first position, which does not affect the cleaning effect. Figure 8 (As shown in the direction), the descent of the scraper 14 can seal the front opening and increase suction. When the cleaning equipment is a wet cleaning equipment, the descent of the scraper 14 can also scrape away any remaining water stains on the ground.

[0044] refer to Figure 9-14 In this embodiment, the cleaning head 1 has a driving device 14 located behind the roller brush 12 along the direction of travel, and the transmission mechanism 15 spans across the roller brush 12. By placing the driving device 14 behind the roller brush 12, space can be effectively saved.

[0045] The cleaning head 1 also includes a cover 16 disposed on the housing 11, and a scraper 14 and a transmission mechanism 15 disposed on the cover 16. The drive unit is fixed inside the housing. The cover 16 can be removed from the cleaning head 1, thus facilitating the replacement of the roller brush 12. When the cover is installed on the cleaning head, the transmission mechanism is connected to the drive unit.

[0046] refer to Figure 9-14The cleaning head 1 is described in detail in the diagram. The drive unit includes a drive member 141 and a power transmission member 142 that is driveably connected to the drive member 141. The drive member 141 is configured such that: when the cleaning head 1 moves in the traveling direction, the drive force is transmitted to the scraper member 14 through the power transmission member 142 and the transmission mechanism 15 to keep the scraper member 14 in a first position; and when the cleaning head 1 moves in the reversing direction, the drive force is transmitted to the scraper member 14 through the power transmission member 142 and the transmission mechanism 15 to keep the scraper member 14 in a second position.

[0047] refer to Figure 11-14 Specifically, the transmission mechanism 15 includes a first transmission member 151 and a second transmission member 152 that is pulsatorically connected to the first transmission member 151. The first transmission member 151 is pulsatorically connected to the power transmission member 142, and the second transmission member 152 is pulsatorically connected to the scraping member 14. The power transmission member 142 includes a first toothed structure 17, and the first transmission member 151 includes a second toothed structure 18. The first toothed structure 17 and the second toothed structure 18 mesh with each other. The first toothed structure 17 can be a gear structure, and the second toothed structure 18 can be a rack structure. The meshing of the gear structure and the rack structure can effectively realize power transmission. At least a portion of the second transmission member 152 extends along the outer periphery of the roller brush 12. The first transmission member 151 can be molded from plastic material or it can be a metal part. In other embodiments, the transmission mechanism 15 can also be pulsatorically connected to the first transmission member 151 in other common forms. The transmission mechanism 15 can also be a linkage structure or other related transmission mechanism 15.

[0048] refer to Figure 11-14 The drive element 141 includes at least one roller 19 that frictionally contacts the surface to be cleaned and is configured to rotate during friction with the surface to generate a driving force. The power transmission element 142 includes a first gear structure 21 and a second gear structure 22 that meshes with the first gear structure 21.

[0049] When the surface cleaning equipment 100 is a wet cleaning equipment, it also includes a cleaning fluid supply system, which includes a liquid distributor 20 (see reference). Figure 13 The liquid distributor 20 is disposed on the cover 16 and is used to distribute cleaning liquid to the roller brush 12. The first transmission member 151 is disposed above the liquid distributor 20. This arrangement can effectively save space.

[0050] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
