[0002] As the pace of life accelerates, people's demand for efficient cleaners is increasing day by day. There are many types of cleaners on the market, but almost every cleaner cannot do without a scraper. The scraper can assist the cleaning parts in cleaning, not only gathering the stains, but also preventing the particles from splashing, and scraping away stubborn stains at once, greatly improving the cleaning power.

[0003] For example, the Chinese utility model patent "Scraper Bar Assembly and Floor Scrubber" with authorization announcement number CN208625586U (application number 201820071249.5) discloses a scraper bar assembly structure, which is easy to disassemble and assemble, so that it can be replaced. The soft rubber scraper bar in the scraper bar assembly is similar to the commonly used scraper bar. The length of the scraper bar is equivalent to the length of the roller brush. The scraper bar is relatively long. When it contacts the ground, the scraper bar moves in different positions with poor consistency due to the garbage on the ground. It is easy to deform and has poor reset ability after deformation. In particular, when used on a ground with large undulations, the scraper bar has poor contact adaptability with the ground, and it is easy for the scraper bar to not fit completely with the ground, affecting the cleaning effect. Utility Model Content

[0004] The first technical problem to be solved by the utility model is to provide a scraper strip assembly which can shorten the length of each scraper blade in the scraper strip, improve the adaptability of the scraper blade to the ground contact, and has strong anti-deformation ability in view of the above-mentioned prior art.

[0005] The second technical problem to be solved by the present invention is to provide a cleaning machine which can ensure the cleaning effect even when used on a ground with large undulations in view of the above-mentioned prior art.

[0006] The utility model solves the above-mentioned first technical problem by adopting the following technical solution: a scraper strip assembly, comprising a bracket and a scraper strip arranged on the bracket, characterized in that the scraper strip comprises a strip-shaped base body and at least two scraper blades arranged along the length on the base body.

[0007] In order to ensure a better cleaning effect, the ends of two adjacent scraper blades are overlapped.

[0008] Preferably, there is an overlapping gap between two adjacent scraper blade sections.

[0009] As an improvement, the base body is provided with two parallel installation lines with a gap, and two adjacent scrapers are respectively installed at different installation line positions on the base body.

[0010] Preferably, each scraper blade has an arc-shaped cross section.

[0011] Preferably, a mounting groove is provided on the bracket along the length direction, and the base is embedded in the mounting groove.

[0012] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a cleaning machine, including a casing with a dust suction port, characterized in that it also includes a scraper bar assembly as mentioned above, and the scraper bar assembly is arranged on the front side of the dust suction port on the casing.

[0013] In order to match the forward and backward movement of the cleaning machine and avoid affecting the garbage from entering the dust suction port when the cleaning machine moves forward, the scraper bar assembly can be set on the housing in a swingable manner.

[0014] Preferably, a driving mechanism is provided in the housing, and the driving mechanism is connected to the bracket to drive the scraper strip assembly to swing up and down.

[0015] Preferably, a mounting seat is provided on the housing, and the bracket is connected to the mounting seat by a rotating shaft so as to swing up and down;

[0016] The driving mechanism comprises a motor and a swing arm connected to a driving end of the motor, and a driving shaft is connected to the swing arm;

[0017] A linkage piece is obliquely arranged on the bracket, a U-shaped groove is opened on the linkage piece, and the drive shaft is placed in the U-shaped groove.

[0018] Compared with the prior art, the utility model has the following advantages: the scraper bar assembly of the utility model divides the scraper bar into at least two scraper blade structures, thus shortening the length of each scraper blade segment and improving its own anti-deformation ability. At the same time, even when the scraper bar is applied to a large undulating ground, each scraper blade segment can relatively independently match the ground shape below it, and there is no relative influence between the scraper blade segments, thereby ensuring the degree of fit with the ground undulation, having strong adaptability to the ground undulation, and thus ensuring the cleaning effect.

[0019] The cleaning machine using the scraper assembly has a long service life and a long replacement period, which reduces the use cost accordingly. In addition, the cleaning machine has good adaptability to various undulating ground surfaces, good cleaning effects, and excellent use experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, the scraper strip assembly in this embodiment includes a bracket 1 and a scraper strip 2 arranged on the bracket 1, wherein the scraper strip 2 includes a strip-shaped base 21 and at least two scraper blades 22 arranged along the length on the base 21. The number of scraper blades 22 can be specifically set according to the length of the scraper strip 2 and the required adaptability to the ground. The higher the adaptability requirement to the ground, the greater the number of scraper blades 22 to be set. The base 21 and the scraper blade 22 in this embodiment are integrally arranged and supported by a variable material, such as silicone commonly used in the prior art, and of course, can also be made of various materials that can achieve the same effect as the scraper strip 2.

[0025] The cross section of the scraper blade 22 is arc-shaped to improve its anti-deformation ability, and the specific bending direction of the scraper blade 22 is specifically determined based on its installation position.

[0026] The base 21 has two parallel installation lines with gaps. The installation lines are not physical structures, but positioning lines during design. Two adjacent scrapers 22 are respectively installed at different installation line positions on the base 21, so that the adaptability under the undulating deformation of the ground can be better improved. In order to ensure a better cleaning effect, the ends of two adjacent scrapers 22 are overlapped to avoid water stains between adjacent scrapers 22. Based on the installation position constrained by the aforementioned installation lines, there is an overlapping gap between the two adjacent scrapers 22.

[0027] The bracket 1 is provided with a mounting groove 11 along the length direction, and the base 21 is embedded in the mounting groove 11 , thereby realizing the installation of the scraper strip 2 on the bracket 1 .

[0028] The scraper bar assembly of the utility model divides the scraper bar 2 into at least two scraper blades 22, thus shortening the length of each scraper blade 22 and improving its own anti-deformation ability. At the same time, even when the scraper bar 2 is applied to a large undulating ground, each scraper blade 22 can relatively independently match the ground shape below it, and there is no relative influence between the scraper blades 22, which ensures the degree of fit with the ground undulation, has strong adaptability to the ground undulation, and thus ensures the cleaning effect.

[0029] The aforementioned scraper bar assembly can be used in various cleaning machines. The installation position of the scraper bar assembly in the cleaning machine is determined by the specific functional requirements of the cleaning machine. For example, it can be set on the front side of the dust suction port 31 of the cleaning machine, and / or on the rear side of the dust suction port 31 of the cleaning machine.

[0030] like Figure 2 and Figure 3 As shown, the cleaning machine in this embodiment includes a housing 3 having a dust suction port 31, and the aforementioned scraper assembly, which is arranged on the front side of the dust suction port 31 on the housing 3. The driving mechanism 4 can adopt various driving mechanisms 4 in the prior art that can drive the scraper 2 to swing up and down, such as the driving mechanism 4 disclosed in the Chinese utility model "A floor brush module for cleaning machine and cleaning machine" with the authorization announcement number CN218852599U.

[0031] The scraper bar assembly in this embodiment can be set on the housing 3 in an up-and-down swinging manner. When in use, when the cleaning machine moves forward, in order to prevent the scraper bar 2 from blocking the suction port 31 and affecting the suction of garbage, the scraper bar assembly is rotated to the upper swing state, thereby opening the suction port 31 and ensuring that the garbage enters the suction port 31. When the cleaning machine moves backward, the scraper bar assembly is rotated to the lower swing state and contacts the ground, thereby playing an auxiliary cleaning role, that is, playing a role in gathering stains, while preventing particles from splashing, and also scraping off stubborn stains, greatly improving the cleaning power.

[0032] Specifically, a bracket 1 is provided in the housing 3 to drive and connect the driving mechanism 4. The driving mechanism 4 autonomously drives the scraper strip assembly to swing up and down according to the forward and backward signals of the cleaning machine.

[0033] In this embodiment, a mounting base 5 is provided on the housing 3, and the bracket 1 is connected to the mounting base 5 by a rotating shaft so as to swing up and down. The driving mechanism 4 includes a motor 41 and a swing arm 42 connected to the driving end of the motor 41, and a driving shaft 43 is connected to the swing arm 42. A linkage member 12 is obliquely provided on the bracket 1, and a U-shaped groove 121 is provided on the linkage member 12, and the driving shaft 43 is placed in the U-shaped groove 121. When driving, the motor 41 can drive the swing arm 42 to rotate forward or reverse, and correspondingly drive the driving shaft 43 to rotate forward or reverse, and then drive the scraper assembly to swing up and down based on the relative position relationship between the driving shaft 43 and the linkage member 12.

[0034] The cleaning machine using the scraper assembly has a long service life and a long replacement period, which reduces the use cost accordingly. In addition, the cleaning machine has good adaptability to various undulating ground surfaces, good cleaning effects, and excellent use experience.
