Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a floor cleaning mechanism and a sweeping robot. Background Technology

[0002] With the advent of the era of smart cleaning appliances, more and more intelligent cleaning robots, such as robotic vacuum cleaners, have appeared on the market. Currently, most robotic vacuum cleaners on the market have a scraper on their bottom, which removes stubborn stains from the floor as the robot moves. However, when the scraper encounters small bumps or uneven surfaces, it can increase resistance, hindering the robot's progress, and may even lift the entire machine, causing the wheels to slip and preventing it from moving further. Utility Model Content

[0003] Therefore, it is necessary to provide a floor scraping mechanism and a sweeping robot to address the problem that the scraper blades of existing sweeping robots encounter raised obstacles on the ground, which increase the resistance of the scraper blades and hinder their progress, and may even lift the entire machine up, causing the wheels of the sweeping robot to slip and become unable to move.

[0004] A floor scraper mechanism includes: a mounting housing having a first mounting opening and a locking hole at its bottom; a bottom cover covering the first mounting opening, one side of the bottom cover being rotatably connected to one side of the mounting housing, and the other side of the bottom cover forming an abutment portion that engages with the locking hole; a scraper blade disposed at the bottom of the bottom cover and located near the abutment portion; and an elastic member having at least a portion located above the abutment portion, one end of the elastic member being connected to the mounting housing, and the other end of the elastic member abutting against the abutment portion to give the abutment portion a downward tendency to move.

[0005] This application provides a floor cleaning mechanism, including a mounting housing, a bottom cover, and an elastic element. The bottom cover fits onto the bottom of the mounting housing and has a scraper blade for contacting the ground. One end of the bottom cover is rotatably connected to the mounting housing, and the other end of the bottom cover has an abutment portion that engages with a locking hole in the mounting housing. These components work together to assemble the bottom cover. Simultaneously, the mounting housing has an elastic element for abutting against the abutment portion. Therefore, when the scraper blade encounters raised obstacles or uneven ground during the robot's movement, the bottom cover, in conjunction with the abutment portion and the elastic element, causes the scraper blade to float up and down relative to the mounting housing. This allows the scraper blade to better conform to the ground and ensures stable operation of the robot. The floor cleaning mechanism of this application has a simple structure. By forming rotating structures and abutment portions on both sides of the bottom cover, the connection between the bottom cover and the mounting housing, as well as the abutment engagement with the elastic element, can be quickly completed. This easily completes the assembly operation while also achieving the floating function of the floor cleaning mechanism.

[0006] In one embodiment, the mounting housing includes a housing body and a mounting portion. The mounting portion is disposed on the housing body and has a mounting cavity with the first mounting opening. The side wall of the mounting cavity has the locking hole. By adopting the above structure, when the bottom cover is closed, it can cooperate with the inner wall of the mounting cavity to limit and fix the roller brush assembly. Simultaneously, the locking hole on the inner wall of the mounting cavity allows the abutting portion to enter the mounting cavity and engage with the locking hole, thereby facilitating a compact design of the mounting housing and bottom cover structure.

[0007] In one embodiment, the bottom cover includes a cover body and the abutment portion. The cover body is adapted to the first mounting port. The bottom cover has a first bracket and a second bracket disposed opposite to each other. The first bracket is rotatably connected to the mounting portion via a pivot. The abutment portion is disposed on the outer side wall of the second bracket, and the scraper is located at the bottom of the second bracket. By adopting the above structure, when the bottom cover is closed at the first mounting port, it is adapted to the first mounting port. This allows the abutment portion to be hidden inside the scraper mechanism, thus preventing collision damage to the abutment portion from external foreign objects when the robot vacuum is working. It also prevents dust and debris from entering the locking hole or affecting the floating fit between the abutment portion and the elastic element.

[0008] In one embodiment, the second bracket has an upwardly protruding baffle plate at the end away from the latch hole. The baffle plate is located inside the mounting cavity and is disposed opposite to the latch hole or the elastic member. By providing the baffle plate, dust and debris entering the mounting cavity can be blocked, preventing them from entering the latch hole or affecting the floating fit between the elastic member and the abutment.

[0009] In one embodiment, the baffle is arc-shaped. Specifically, the mounting cavity has an arc-shaped inner wall. By setting the baffle to an arc shape, interference and collision between the baffle and the inner wall of the mounting cavity can be effectively avoided when the bottom cover rotates counterclockwise.

[0010] In one embodiment, one of the mounting housing and the bottom cover is provided with a pivot, and the other of the mounting housing and the bottom cover is provided with a shaft hole. The pivot is rotatably engaged in the shaft hole. By adopting the above structure, the operator can not only achieve the rotation setting of the mounting housing by the cooperation of the pivot and the shaft hole, but also achieve the engagement of the pivot and the shaft hole by pushing, thereby quickly installing the mounting housing and making the operation simple and convenient.

[0011] In one embodiment, the bottom cover further includes a resilient connecting ear disposed on the side wall of the first bracket, and the resilient connecting ear has the pivot or the shaft hole. By employing the above structure, when the user installs or removes the bottom cover, the resilient connecting ear can be squeezed to cause elastic deformation, thereby separating the pivot from the side wall with the shaft hole, making it easier to separate and connect the pivot and the shaft hole.

[0012] In one embodiment, the inner wall of the first mounting port is recessed inward to form a first clearance groove, which is located on the side of the resilient connecting ear away from the first bracket. The first clearance groove provides clearance space, allowing the user's hand to reach in and press the resilient connecting ear from the front, causing the rotating shaft to separate from the side wall with the shaft hole.

[0013] In one embodiment, the inner wall of the first mounting opening is recessed inward to form a second relief groove, and at least a portion of the resilient connecting lug is located in the second relief groove. The second relief groove allows for the adaptation of resilient connecting lugs with longer mounting lever arms, thereby achieving a more labor-saving effect.

[0014] In one embodiment, the elastic element is disposed on the outside of the mounting portion, and the abutting portion extends out of the mounting portion through the locking hole and abuts against the elastic element. The end of the elastic element away from the abutting portion is connected to the housing body or the mounting portion. By placing the elastic element on the outside of the mounting portion and elastically engaging with the abutting portion, the size of the mounting cavity can be reduced, thereby improving the space utilization of the floor scraper mechanism. This also effectively reduces the possibility of dust and debris entering the mounting cavity and entering between the elastic element and the abutting portion, avoiding any impact on the floating engagement between the abutting portion and the elastic element.

[0015] In one embodiment, the two ends of the abutting portion abut against the bottom wall of the housing body and the bottom wall of the card hole, respectively.

[0016] In one embodiment, the elastic element is integrally formed with the mounting housing, and the elastic element is a flexible rubber strip that can be bent. This reduces the assembly work of the floor scraper mechanism, improves assembly efficiency, and ensures that the abutment portion can accurately align and abut with the elastic element during the installation of the bottom cover.

[0017] In one embodiment, one of the bottom cover and the scraper is provided with a mounting groove, and the other of the bottom cover and the scraper is adapted to the mounting groove for installation. The mounting groove provides a positioning function for fixing the scraper, thereby improving assembly efficiency.

[0018] In one embodiment, the scraper strip and the bottom cover are connected using an adhesive coating process. This results in a strong and durable connection.

[0019] The second aspect of this application provides a robotic vacuum cleaner.

[0020] A robotic vacuum cleaner includes: the aforementioned floor scraping mechanism; and a roller brush assembly rotatably disposed between the mounting housing and the bottom cover. The bottom cover has an opening opposite to the first mounting port, and at least a portion of the roller brush assembly protrudes from the opening. The robotic vacuum cleaner provided in the second aspect of this application, by employing the floor scraping mechanism of any of the above embodiments, allows the bottom cover to cooperate with the mounting housing to limit and fix the roller brush assembly when closed. The floor scraping mechanism includes a mounting housing, a bottom cover, and an elastic element. The bottom cover is fitted onto the bottom of the mounting housing and has a scraper for contacting the ground. By forming a rotating structure and an abutment portion on both sides of the bottom cover, the connection between the bottom cover and the mounting housing, as well as the abutment cooperation with the elastic element, can be quickly completed. This easily completes the assembly operation while also realizing the floating function of the floor scraping mechanism.

[0021] In one embodiment, a limiting member is also included. The bottom of the mounting housing is provided with a second mounting port. The limiting member is adapted to be installed at the second mounting port. The limiting member and the mounting housing cooperate to form a mounting hole. The mounting hole is adapted to be installed with the connecting shaft of the roller brush assembly. Attached Figure Description

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0040] The following describes some embodiments of the floor scraper mechanism of the present invention with reference to the accompanying drawings.

[0041] like Figures 1 to 8 As shown, this embodiment discloses a floor scraper mechanism, including: a mounting housing 1, the bottom of which is provided with a first mounting opening 101 and a locking hole 102; a bottom cover 2, which is disposed on the first mounting opening 101, one side of the bottom cover 2 is rotatably connected to one side of the mounting housing 1, and the other side of the bottom cover 2 forms an abutment portion 22, which is locked in the locking hole 102; a scraper 3, which is disposed on the bottom of the bottom cover 2 and located on the side close to the abutment portion 22; and an elastic member 4, at least a portion of which is located above the abutment portion 22, one end of which is connected to the mounting housing 1, and the other end of which abuts against the abutment portion 22 to give the abutment portion 22 a downward tendency.

[0042] This application provides a floor cleaning mechanism, including a mounting housing 1, a bottom cover 2, and an elastic element 4. The bottom cover 2 is fitted onto the bottom of the mounting housing 1 and has a scraper 3 for contacting the ground. One end of the bottom cover 2 is rotatably connected to the mounting housing 1, and the other end of the bottom cover 2 has an abutment portion 22 that engages with a locking hole 102 in the mounting housing 1, working together to assemble the bottom cover 2. Simultaneously, the mounting housing 1 has an elastic element 4 for abutting against the abutment portion 22. Therefore, when the scraper 3 encounters protruding obstacles or uneven ground during the robot's movement, the bottom cover 2, in cooperation with the abutment portion 22 and the elastic element 4, can cause the scraper 3 to float up and down relative to the mounting housing 1, allowing the scraper 3 to better conform to the ground and ensuring stable operation of the robot. The floor cleaning mechanism of this application has a simple structure. By forming rotating structures and abutment portions 22 on both sides of the bottom cover 2, the connection between the bottom cover 2 and the mounting housing 1 and the abutment engagement with the elastic element 4 can be quickly completed, easily completing the assembly operation while also achieving the floating function of the floor cleaning mechanism.

[0043] like Figures 5 to 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting housing 1 includes a housing body 11 and a mounting part 12. The mounting part 12 is disposed on the housing body 11, and the mounting part 12 has a mounting cavity 103 with a first mounting opening 101. The side wall of the mounting cavity 103 has a locking hole 102. By adopting the above structure, when the bottom cover 2 is closed, it can cooperate with the inner wall of the mounting cavity 103 to limit and fix the roller brush assembly. At the same time, the inner wall of the mounting cavity 103 has a locking hole 102, and the abutting part 22 will enter the mounting cavity 103 and abut against the locking hole 102, thereby facilitating the compact design of the mounting housing 1 and the bottom cover 2.

[0044] like Figures 5 to 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom cover 2 includes a cover body 21 and an abutment portion 22. The cover body 21 is adapted to be installed in the first mounting port 101. The bottom cover 2 has a first bracket 211 and a second bracket 212 arranged opposite to each other. The first bracket 211 is rotatably connected to the mounting portion 12 through a rotating shaft 24. The abutment portion 22 is disposed on the outer side wall of the second bracket 212, and the scraper 3 is located at the bottom of the second bracket 212. By adopting the above structure, when the bottom cover 2 is closed at the first mounting port 101, the bottom cover 2 is adapted to be installed in the first mounting port 101. Thus, the abutment portion 22 can be hidden inside the floor scraper mechanism. Therefore, when the sweeping robot is working, it can avoid collision damage to the abutment portion 22 caused by foreign objects. It can also prevent dust and garbage from entering the card hole 102 or affecting the floating fit between the elastic member 4 and the abutment portion 22.

[0045] like Figures 5 to 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second bracket 212 has an upwardly protruding baffle 23 at one end away from the slot 102. The baffle 23 is located inside the mounting cavity 103 and is disposed opposite to the slot 102 or the elastic member 4. By providing the baffle 23, the baffle 23 can block dust and debris from entering the mounting cavity 103, preventing dust and debris from entering the slot 102 or affecting the floating fit between the elastic member 4 and the abutment 22.

[0046] like Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the baffle plate 23 is arc-shaped. Specifically, the mounting cavity 103 has an arc-shaped inner wall. By setting the baffle plate 23 to an arc shape, interference and collision between the baffle plate 23 and the inner wall of the mounting cavity 103 can be effectively avoided when the bottom cover 2 rotates counterclockwise.

[0047] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: one of the mounting housing 1 and the bottom cover 2 is provided with a rotating shaft 24, and the other of the mounting housing 1 and the bottom cover 2 is provided with a shaft hole 104, and the rotating shaft 24 is rotatably engaged in the shaft hole 104. By adopting the above structure, the operator can not only realize the rotation setting of the mounting housing 1 through the cooperation of the rotating shaft 24 and the shaft hole 104, but also realize the engagement of the rotating shaft 24 with the shaft hole 104 through the pushing action, thereby quickly realizing the installation of the mounting housing 1, and the operation is simple and convenient.

[0048] like Figure 4 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom cover 2 also includes an elastic connecting ear 25, which is disposed on the side wall of the first bracket 211, and the elastic connecting ear 25 is provided with a rotating shaft 24 or a shaft hole 104. By adopting the above structure, when the user disassembles or assembles the bottom cover 2, he / she can squeeze the elastic connecting ear 25 to make it elastically deform, thereby separating the rotating shaft 24 from the side wall with the shaft hole 104, and more easily realizing the separation and connection of the rotating shaft 24 and the shaft hole 104.

[0051] like Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the elastic member 4 is disposed on the outside of the mounting portion 12, the abutting portion 22 extends out of the mounting portion 12 through the snap hole 102 and abuts against the elastic member 4, and the end of the elastic member 4 away from the abutting portion 22 is connected to the housing body 11 or the mounting portion 12. By disposing the elastic member 4 on the outside of the mounting portion 12 and elastically engaging with the abutting portion 22, the size of the mounting cavity 103 can be reduced, thereby improving the space utilization of the floor scraper mechanism and effectively reducing the possibility of dust and debris entering the mounting cavity 103 and entering between the elastic member 4 and the abutting portion 22, thus avoiding any impact on the floating engagement between the abutting portion 22 and the elastic member 4.

[0052] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the two ends of the abutting part 22 abut against the bottom wall of the housing body 11 and the bottom wall of the card hole 102, respectively.

This reduces the assembly work of the floor scraper mechanism, improves assembly efficiency, and ensures that the abutment portion 22 can accurately align and abut against the elastic member 4 when the bottom cover 2 is installed.

[0054] In addition to the features of the above embodiments, this embodiment further specifies that: one of the bottom cover 2 and the scraper 3 is provided with a mounting groove, and the other of the bottom cover 2 and the scraper 3 is adapted to the mounting groove for installation.

[0055] In addition to the features of the above embodiments, this embodiment further specifies that the scraper strip 3 and the bottom cover 2 are connected by an adhesive coating process. This results in a strong and durable connection.

[0056] The second aspect of this application provides a robotic vacuum cleaner.
