[0034] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present invention. The terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] As Figures 1 to 5 shown, the floor sweeper 100 provided by an embodiment of the present invention includes a drive assembly 110, two floor sweeping heads 130, and an auxiliary pushing member 150. Among them, output shafts 111 are provided on both sides of the drive assembly 110. The two floor sweeping heads 130 are respectively fixedly connected to the two output shafts 111. The auxiliary pushing member 150 is provided between the two floor sweeping heads 130. Specifically, the fixed connection manner between the floor sweeping head 130 and the output shaft 111 can be a detachable connection or a permanently fixed connection.

[0038] In the floor sweeper 100, the auxiliary pushing member 150 can assist in pushing the garbage between the two sweeping heads 130, so as to avoid garbage residue in the area between the two sweeping heads 130 during cleaning, achieving a complete cleaning effect and improving the cleaning effect.

[0039] The auxiliary pushing member 150 is located between the two sweeping heads 130. The size of the auxiliary pushing member 150 can be specifically set according to the distance between the two sweeping heads 130, as long as it can clean the area between the two sweeping heads 130. Therefore, the setting of the auxiliary pushing member 150 does not change the size of the commonly used sweeping head 130. It can be understood that the distance between the auxiliary pushing member 150 and the sweeping head 130 needs to be greater than zero to avoid interference with the sweeping head 130 and affecting the operation of the sweeping head 130.

[0040] Optionally, on the side of the sweeping head 130 close to the auxiliary pushing member 150, the bristles on the sweeping head 130 are inclined inward from the free end, that is, the bristles on the sweeping head 130 are inclined toward the side close to the auxiliary pushing member 150 from the free end, thereby increasing the cleaning range of the sweeping head 130.

[0041] It can be understood that the sweeping head 130 is fixedly connected to the output shaft 111, so that the sweeping head 130 rotates with the rotation of the output shaft 111 to better achieve the purpose of cleaning. The auxiliary pushing member 150 is used to push the garbage between the two sweeping heads 130 to move forward together with the floor sweeper. During this process, the garbage in front of the auxiliary pushing member 150 increases and slides to the front side of the sweeping head 130, and then continues to move forward under the drive of the sweeping head 130.

[0042] It can be understood that the front side of the auxiliary pushing member 150 refers to the side of the auxiliary pushing member 150 pointing to the cleaning direction. Correspondingly, the front side of the cleaning head 130 refers to the side of the cleaning head pointing to the cleaning direction. In addition, in order to avoid the setting of the auxiliary pushing member 150 affecting the operation of the cleaning head 130, there is a gap between the auxiliary pushing member 150 and the cleaning head 130.

[0043] Generally, the garbage between the two sweeping heads 130 is mostly garbage debris. Of course, in other feasible cases, the garbage between the two sweeping heads 130 is not limited to garbage debris, and may also be larger-shaped garbage.

[0044] In this embodiment, the sweeping head 130 is a rotary brush. It can be understood that in other feasible embodiments, the sweeping head is not limited to a rotary brush, and can also be any other commonly used sweeping head in this field.

[0045] It can be understood that the auxiliary pushing member 150 is used to assist in pushing the garbage between the two sweeping heads 130 forward. Therefore, when the floor sweeper 100 is working, the lower end of the auxiliary pushing member 150 contacts the bottom surface or there is a gap between the auxiliary pushing member 150 and the bottom surface that does not affect cleaning.

[0046] Optionally, the auxiliary pusher 150 has a front side 153 for contacting the accumulated garbage. On the surface perpendicular to the axial direction of the sweeping head 130, the projection of the front side 153 of the auxiliary pusher 150 is tangent to or deviated from the projection of the sweeping head 130, and the projection of the front side 153 of the auxiliary pusher 150 is located on the front side of the projection of the sweeping head 130. This facilitates the sliding of the garbage on the front side of the auxiliary pusher 150 to the front side of the sweeping head 130, avoiding the accumulation of the garbage pushed by the auxiliary pusher 150 at the position between the auxiliary pusher 150 and the sweeping head 130 and affecting the operation of the sweeping head 130. The front side of the auxiliary pusher 150 refers to the side along the forward direction when the auxiliary pusher 150 works. Correspondingly, the front side of the sweeping head 130 refers to the side along the forward direction when the sweeping head 130 works.

[0047] In this embodiment, the auxiliary pusher 150 is a scraper. The lower side of the auxiliary pusher 150 is used to contact the ground to push the garbage on the ground forward.

[0048] Optionally, the material of the auxiliary pusher 150 is thermoplastic elastomer (TPE, Thermoplastic Elastomer), thermoplastic vulcanizate (TPV, Thermoplastic Vulcanizate) or polyvinyl chloride (PVC, Polyvinylchloride). The thermoplastic elastomer (TPE, Thermoplastic Elastomer), thermoplastic vulcanizate (TPV, Thermoplastic Vulcanizate) or polyvinyl chloride (PVC, Polyvinylchloride) has relatively low friction noise with the bottom surface, so that the friction sound between the auxiliary pusher 150 and the bottom surface is small, reducing the noise generated during the cleaning activity of the sweeper 100, and at the same time avoiding damage to the ground due to excessive friction between the auxiliary pusher 150 and the ground.

[0049] In addition, the thermoplastic elastomer (TPE, Thermoplastic Elastomer), thermoplastic vulcanizate (TPV, Thermoplastic Vulcanizate) or polyvinyl chloride (PVC, Polyvinyl chloride) also has the characteristic of wear resistance, thus avoiding excessive wear of the auxiliary pusher 150 due to friction with the ground and affecting the cleaning effect.

[0050] Optionally, a wear-resistant layer is provided on the bottom side of the auxiliary pusher 150 to reduce the damage caused by the friction between the auxiliary pusher 150 and the ground. Specifically, the wear-resistant layer can be Teflon.

[0051] It can be understood that the material of the auxiliary pusher 150 is not limited to thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), or polyvinyl chloride (PVC), and can also be a wooden board or polypropylene (PP).

[0052] In this embodiment, the front side 153 of the auxiliary pusher 150 is a flat surface. The structure is simple and convenient for processing. Optionally, in another feasible embodiment, the front side 153 of the auxiliary pusher 150 is not limited to a flat surface and can also be in any other regular or irregular shape.

[0053] Furthermore, in this embodiment, the auxiliary pusher 150 is in a plate shape, and the thickness of each position of the auxiliary pusher 150 except the anti - detachment part 151 is exactly the same. The structure of the auxiliary pusher 150 is simple and convenient for processing. It can be understood that in another feasible embodiment, the structure of the auxiliary pusher is not limited to a plate shape, and the auxiliary pusher can be in any regular or irregular shape as long as it can push the garbage between the two sweeping heads forward.

[0054] Optionally, a slip - increasing layer is provided on the front side 153 of the auxiliary pusher 150 to increase the smoothness of the front side of the auxiliary pusher 150. The setting of the slip - increasing layer can reduce the garbage adhering to the auxiliary pusher 150. And when the operator subsequently cleans the auxiliary pusher 150, the garbage adhering to the auxiliary pusher 150 can be easily washed off, reducing the operator's work intensity.

[0055] Specifically, the slip - increasing layer can be a slip - increasing coating or a slip - increasing film. More specifically, the slip - increasing layer can be a paint layer.

[0056] In this embodiment, the driving component 110 includes a transmission component, and the transmission component includes a housing 113. The auxiliary pusher 150 is fixedly connected to the housing 113.

[0057] Specifically, in this embodiment, the housing 113 includes a main body 112 and two cover bodies 114 respectively provided on both sides of the main body 112 and fixedly connected to the main body 112. The auxiliary pusher 150 is fixedly connected to the main body 112. Of course, in another feasible embodiment, the auxiliary pusher 150 can also be fixedly connected to the cover body or other structures on the sweeper 100, as long as during the working process of the sweeper 100, the auxiliary pusher 150 can be located between the two sweeping heads 130 and can push the garbage between the two sweeping heads 130 forward.

[0058] Specifically, in this embodiment, along the direction in which the two sweeping heads 130 are arranged, an anti - detachment groove 1121 penetrating the main body 112 is provided on the main body 112, and an anti - detachment portion 151 matching the anti - detachment groove 1121 is provided on the auxiliary pushing member 150. Both of the two cover bodies 114 have a limiting surface 1141 that abuts against the corresponding side of the auxiliary pushing member 150. By the abutment of the limiting surface 1141 of the cover body 114 against the auxiliary pushing member 150, the auxiliary pushing member 150 is prevented from sliding out from both ends of the anti - detachment groove 1121.

[0059] Specifically, the anti - detachment groove 1121 has a retaining wall 1122 that is not parallel to the vertical direction, and the anti - detachment portion 151 has a retaining surface 1511 that matches the retaining wall 1122. And the retaining wall 1122 is located on the side closer to the bottom surface of the retaining surface 1511, thereby preventing the anti - detachment portion 151 from sliding out of the anti - detachment groove 1211 in a direction perpendicular to the extension of the anti - detachment groove 1211.

[0060] It can be understood that the above - mentioned vertical direction refers to the direction perpendicular to the horizontal plane during the use of the sweeper 100.

[0061] More specifically, in this embodiment, the anti - detachment portion 151 is in a swallow - tail shape. Correspondingly, the anti - detachment groove 1121 is also in a swallow - tail shape. It can be understood that in other feasible embodiments, the anti - detachment portion 151 is not limited to being in a swallow - tail shape, as long as it can prevent the anti - detachment portion 151 from slipping out of the anti - detachment groove 1121 in a direction perpendicular to the extension of the anti - detachment groove 1121.

[0062] Of course, in other feasible embodiments, the auxiliary pushing member can also be fixedly connected to the main body, that is, without the limiting effect of the cover body. For example, the auxiliary pushing member is welded, screwed, or clamped to the main body, etc.

[0063] In this embodiment, the anti - detachment groove 1121 and the limiting surface 1141 limit the auxiliary pushing member 150 from different directions, making the auxiliary pushing member 150 relatively fixed to the main body 112. And in this embodiment, the main body 112 and the cover body 114 are detachably connected. After the main body 112 and the cover body 114 are disassembled, the anti - detachment portion 151 can slide out of the anti - detachment groove 1121, thereby realizing the detachability of the auxiliary pushing member 150. Thus, after the auxiliary pushing member 150 is worn, the auxiliary pushing member 150 can be replaced to ensure the cleaning effect of the sweeper 100.

[0064] Optionally, in other feasible embodiments, the auxiliary pushing member has a front side surface. Along the vertical direction, the distance between the bottom edge of the front side surface and the main body is adjustable, so that after the bottom edge of the auxiliary pushing member is worn, the distance between the front side surface of the auxiliary pushing member and the main body can be adjusted to make the bottom edge of the front side surface of the auxiliary pushing member abut against the bottom surface or maintain a preset distance from the bottom surface.

[0065] Specifically, the distance between the bottom edge of the front side of the auxiliary pusher and the housing can be adjusted by connecting the auxiliary pusher to the housing in a vertically telescopic manner or with the position of the auxiliary pusher adjustable in the vertical direction.

[0066] For example, in a feasible embodiment, the housing is provided with fixing holes, and the auxiliary pusher is provided with waist-shaped slots that match the fixing holes and extend in the vertical direction. The auxiliary pusher is fixedly connected to the housing by screws, and the screw rod of the screw passes through the waist-shaped slot and is threadedly connected to the housing.

[0067] Optionally, in a feasible embodiment, the auxiliary pusher 150 is located on the front side of the housing 113. This reduces the contact between the housing 113 and the garbage, ensuring the cleanliness of the housing 113. Additionally, reducing the contact between the housing 113 and the garbage can also reduce the corrosion of the housing 113 by water, oxygen, etc. in the garbage.

[0068] Of course, in other feasible embodiments, the auxiliary pusher and the housing are not limited to detachable connections, nor are they limited to other forms of fixed connections. The auxiliary pusher and the housing can also be integrally formed. Specifically, the auxiliary pusher can be integrally formed with the main body or with the cover. Of course, in a feasible embodiment, if the main body and the cover are integrally formed, the auxiliary pusher can be directly integrally formed with the housing.

[0069] Specifically, in this embodiment, the drive assembly 110 further includes a motor connected to the transmission assembly. Specifically, the transmission assembly is a gear transmission assembly. It can be understood that in other feasible embodiments, the transmission assembly is not limited to a gear transmission assembly and can also be other common transmission structures that can transmit the rotation of the output shaft of the motor to the sweeping head so that the sweeping head can operate in a preset manner.

[0070] Optionally, the distance between the auxiliary pusher 150 and the sweeping head 130 is 0.5 to 3 mm. On the one hand, the auxiliary pusher 150 does not affect the operation of the sweeping head 130. On the other hand, the auxiliary pusher 150 can effectively push the garbage between the two sweeping heads 130 forward to achieve a complete cleaning effect.

[0071] As Figure 6 shown, in the floor sweeper provided by another embodiment of the present invention, the bottom edge 254 of the front side 253 of the auxiliary pusher 250 has convex points 256. Starting from the convex points 256, while the bottom edge 254 gradually extends to both sides, it also gradually deviates backward, so that the garbage on the front side of the auxiliary pusher 250 can move more smoothly to the front side of the sweeping head, thereby reducing the thrust force received by the auxiliary pusher 250 during operation.

[0072] In this embodiment, the bump 256 is located at the center of the bottom edge 254. Of course, in other feasible embodiments, the position of the bump 256 is not limited to the middle position of the bottom edge 254, and it can also be a position biased towards one of the sweeping heads.

[0073] Specifically, in this embodiment, the bottom edge 254 of the front side 253 of the auxiliary pusher 250 is V-shaped. It can be understood that in other feasible embodiments, the bottom edge 254 of the front side 253 of the auxiliary pusher 250 is not limited to being V-shaped, and it can also be in regular or irregular shapes such as a parabolic shape.

[0074] Optionally, in a feasible embodiment, the bump can be located at one side edge of the bottom edge, that is, the bottom edge is inclined towards one side of one of the sweeping heads, so that the garbage in front of the auxiliary pusher can smoothly move to the front of the sweeping head on that side.

[0075] As Figure 7 shown, in the floor sweeper provided by another embodiment of the present invention, the auxiliary pusher 350 has an inclined portion 355 that bends forward from the bottom edge 354 of the front side 353, thereby reducing the difficulty of pushing the garbage forward and making it easier to push the garbage between the two sweeping heads forward, improving the cleaning effect on the area between the two sweeping heads.

[0076] It should be noted that the bottom edge 354 of the front side 353 of the auxiliary pusher 350 contacts the bottom surface.

[0077] Furthermore, in this embodiment, the bottom side of the auxiliary pusher 350 is pointed, which can more smoothly insert under the garbage, thereby more smoothly pushing the garbage forward.

[0078] Optionally, in other feasible embodiments, the auxiliary pusher is not limited to a scraper. For example, in the floor sweeper 400 provided by another embodiment of the present invention, the auxiliary pusher 450 is a straight row brush, for details, refer to Figure 8 . Optionally, the bristles on the straight row brush are hard planted bristles arranged in rows.

[0079] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0080] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
