Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning robots, in particular to a pushing mechanism, a dust box mechanism and a cleaning robot. BACKGROUND

[0002] During the daily cleaning and garbage collection process of the dust box of the cleaning robot, garbage may be mixed with residues, oil stains or sewage and other dust particles and the like to form a solidified mixture, and even stick to the dust inlet of the dust box, so that the fan cannot drive these dust particles, and the subsequent garbage collection is blocked. Most of the cleaning robots on the market do not have a structure design scheme to avoid this risk. The current practice is mainly that the consumer proposes to dump garbage in the dust box, and then manually removes it by using a tool. This cleaning mode is time-consuming and laborious, and the cleaning efficiency is low, which cannot meet the efficiency requirements of the automation and intelligentization of the cleaning robot. SUMMARY

[0003] Therefore, it is necessary to provide a pushing mechanism, a dust box mechanism and a cleaning robot which can solve the problem of stubborn dust particles blocking the subsequent garbage collection at the dust inlet of the dust box.

[0004] A pushing mechanism comprises a scraping component, a first limiting portion is arranged on the scraping component, and the scraping component is used for scraping dirt on the contact surface; an eccentric component is matched with the first limiting portion of the scraping component; a driving component is connected with the eccentric component, the driving component is used for driving the eccentric component to reciprocate on the first limiting portion and form a first position and a second position, and the eccentric component drives the scraping component to reciprocate when reciprocating on the first limiting portion.

[0005] The application discloses a propelling mechanism. Eccentric components are connected with a scraping component and a driving component. Under the action of the driving component, the eccentric components perform eccentric motion and drive the scraping component to perform eccentric motion. When the eccentric components cooperate with the first limiting part on the scraping component, the scraping component can move forward and backward and / or up and down relative to the contact surface during the eccentric motion, that is, the scraping component can swing back and forth under the action of the first limiting part and the eccentric components. The propelling mechanism can make the scraping component move forward and backward and / or up and down relative to the contact surface, thereby providing technical support for the scraping component to push and scrape the material on the contact surface. When the propelling mechanism is applied to a dust box of a cleaning robot, the dust particles in the front end of the dust box can be scraped to the rear end through the forward and backward scraping action of the propelling mechanism, thereby solving the problem that the stubborn dust particles block the dust collecting port of the dust box and affect the collection of subsequent garbage. The up and down movement of the propelling mechanism can avoid pushing the dust particles back to the dust collecting port of the dust box. The propelling mechanism has the advantages of simple structure, good stability, low cost and batch production.

[0006] Optionally, the eccentric component is at least one of an eccentric wheel, a cam, an eccentric connecting rod assembly or a combination of the above structures.

[0007] Optionally, in some embodiments, the eccentric component is composed of an eccentric wheel body and a motor shaft sleeve. An eccentric shaft is arranged on one side of the eccentric wheel body, and a limiting shaft is arranged on the other side of the eccentric wheel body. A second connecting hole is arranged on one side of the motor shaft sleeve. The motor shaft sleeve is connected with the limiting shaft of the eccentric wheel body through the second connecting hole.

[0008] Optionally, the driving component is a driving motor. A first connecting hole is arranged on the side of the motor shaft sleeve away from the second connecting hole, and the first connecting hole is an eccentric hole. The rotating shaft of the driving motor is connected with the first connecting hole of the motor shaft sleeve. The motor shaft sleeve is connected with the driving motor and the eccentric wheel body, which is conducive to improving the stability of the connection between the driving component and the eccentric component and improving the structural reliability of the propelling mechanism. In addition, the rotating shaft of the driving motor can drive the motor shaft sleeve to perform eccentric motion, so that the first scraping member can drive the entire scraping component to move up and down, thereby simplifying the structure of the propelling mechanism.

[0009] In one embodiment, the scraping component includes a first scraping member, the first scraping member includes a scraping body and a cleaning arm, the scraping body is connected with one end of the cleaning arm, the other end of the cleaning arm can abut against the contact surface, and the first limiting part is arranged on the scraping body.

[0010] The aforementioned propulsion mechanism further defines that: the scraping assembly includes a first scraping member, wherein a first limiting part is disposed on the scraping body, a cleaning arm is connected to the scraping body, the cleaning arm is used to contact the contact surface, and the cleaning arm generates a scraping and scraping force on the contact surface, and scrapes the dust particles in the front end of the dust box to the rear end for collection.

[0011] Optionally, a flexible cleaning component or scraper is connected to the side of the cleaning arm near the contact surface, thereby making the contact between the cleaning arm and the contact surface more compact, which is beneficial for cleaning and collecting dirt that has been mixed and solidified by residues, oil stains, or sewage and other dust particles.

[0012] In one embodiment, the first limiting part is a first limiting hole, and the first limiting hole is configured such that the height of the planes on both sides along the scraping direction of the cleaning arm is higher than the height of the plane at the center of the first limiting hole.

[0013] The aforementioned propulsion mechanism is further defined as follows: the first limiting hole is an elongated hole, the first limiting hole is horizontally arranged on the scraping body, and the shape of the first limiting hole is such that the height of the plane containing the two side holes where the cleaning arm forms the first and second positions in the scraping direction is higher than the height of the plane containing the center position of the first limiting hole. That is, the first limiting hole can be an elongated arc-shaped hole, a U-shaped hole, or other arc-shaped structure extending along the scraping direction of the cleaning arm.

[0014] Optionally, the eccentric component is mounted on the first puller member after the eccentric shaft of the eccentric component passes through the first limiting hole.

[0015] In some embodiments, the drive motor is fixed to the support member, and the drive motor, motor bushing, and eccentric assembly are eccentrically engaged. The drive motor bushing causes the first scraping member to move. Specifically, the motor shaft rotates clockwise, causing the motor bushing to be in an eccentric rotation state (the drive motor shaft and motor bushing are in the first position), at which point the first scraping member is in a downward pressing action. During the movement, the cleaning arm of the first scraping member is in motion. The eccentric column of the eccentric assembly is in the first position, and the cleaning arm of the first scraping member is in front of the foremost dust particles. When the eccentric assembly rotates counterclockwise by 0°–90°–180°, it causes the first scraping member to move away from the first position, thereby pushing the dust particles to accumulate in a position away from the first direction.

[0016] In some embodiments, the drive motor is fixed, and the drive motor and motor bushing are eccentrically coupled, causing the scraping assembly to move by driving the motor bushing. Specifically, the drive motor shaft rotates clockwise, causing the motor bushing to be in an eccentric rotation state (the drive motor shaft and motor bushing are in the second position), at which time the first scraping member of the scraping assembly is in a lifting action. During operation, the cleaning arm of the first scraping member is also in a moving state. The eccentric column of the eccentric assembly is in the second position, and the cleaning arm of the first scraping member is at its rearmost end (in front of the scraped dust particles). When rotating counterclockwise 180°~270°~0°, the scraping assembly moves towards the first position. In conjunction with the lifting operation of the first scraping member, the scraping assembly moves diagonally upward. This prevents the pushed-back dust particles from being pushed back into the dust box inlet.

[0017] In one embodiment, the prying assembly further includes a second prying member connected to the first prying member. The second prying member is provided with a second limiting part, which is connected to the first limiting part. The eccentric component is adapted to the second limiting part.

[0018] The aforementioned propulsion mechanism further defines that the first and second pulling members cooperate to form a pulling assembly. A second limiting portion on the second pulling member is connected to a first limiting portion on the first pulling member. This allows the eccentric shaft of the eccentric assembly to move within the range defined by the first and second limiting portions. Optionally, the eccentric shaft of the eccentric assembly is adapted to the width and inner diameter of the second limiting portion, and the eccentric shaft can only move along the length direction of the second limiting portion. The second limiting portion makes the eccentric motion trajectory of the eccentric assembly more stable, and the operational reliability of the propulsion mechanism higher.

[0019] In one embodiment, the second limiting part is a second limiting hole, and the eccentric component can move along the length direction of the second limiting hole.

[0020] The aforementioned propulsion mechanism further defines the second limiting part as a second limiting hole. Optionally, the second limiting hole is an elongated hole, into which the eccentric shaft of the eccentric component can be inserted, and the eccentric shaft is adapted to the width and inner diameter of the second limiting hole, thereby restricting the eccentric shaft to move up and down along the length direction of the second limiting hole. The above design is simple in structure, easy to manufacture, and low in cost.

[0021] In one embodiment, the cleaning arm is arranged intersecting with the scraping body.

[0022] The aforementioned propulsion mechanism further defines that the cleaning arm and the scraping body are intersecting, thereby cooperating with the structure of the first limiting part, which enables the cleaning arm to have a tighter contact with the contact surface and better scraping and scraping performance.

[0023] In one embodiment, the eccentric assembly includes an eccentric wheel body, an eccentric shaft, and a limiting shaft. The eccentric shaft and the limiting shaft are respectively disposed on opposite sides of the eccentric wheel body. The eccentric wheel body is sandwiched between the first pulling member and the second pulling member. The eccentric shaft is adapted to the second limiting part, and the limiting shaft is adapted to the first limiting part.

[0024] The aforementioned propulsion mechanism further specifies that: the eccentric wheel body of the eccentric component is sandwiched between the first and second puller components; the first puller component, the eccentric wheel body, and the second puller component are assembled to form a sandwich structure; and the eccentric shaft of the eccentric wheel body cooperates with the second limiting part, and the limiting shaft cooperates with the first limiting part, thereby making the assembly between the eccentric component and the first and second puller components tighter, effectively preventing the eccentric component from shifting during movement, and improving the structural stability of the propulsion mechanism.

[0025] A dustbin mechanism for use in a cleaning robot includes: a housing assembly having a receiving cavity inside, the housing assembly having a dust inlet and an air outlet communicating with the receiving cavity; a propulsion mechanism as described in any of the preceding claims, the propulsion mechanism being disposed within the receiving cavity, a drive assembly capable of driving a scraping assembly to reciprocate between the dust inlet and a side opposite to the dust inlet, and the drive assembly capable of driving the scraping assembly to reciprocate between the top wall and the bottom wall of the receiving cavity.

[0026] The second aspect of this application discloses a dustbin mechanism, including a housing assembly and a propulsion mechanism as described above. By incorporating the propulsion mechanism as described above, the dustbin mechanism acquires the function of any of the aforementioned propulsion mechanisms. The propulsion mechanism is disposed within the receiving cavity of the housing assembly, and it pulls dust particles from the dust inlet to the rear end, thus solving the problem of stubborn dust particles clogging the dust inlet of the dustbin mechanism for subsequent waste collection.

[0027] In one embodiment, the prying assembly is provided with a third limiting part, and a protrusion is formed on the inner wall of the housing assembly. The pushing mechanism is adapted to the protrusion on the inner wall of the housing assembly through the third limiting part.

[0028] The dust box mechanism described above is further defined as follows: a third limiting part is provided on the scraping component, specifically, the third limiting part is provided on the first scraping component.

[0029] Optionally, the third limiting part is a third limiting hole, and a limiting post is provided on the housing assembly. After the limiting post of the housing assembly passes through the third limiting hole, the propulsion mechanism is set on the housing assembly.

[0030] Optionally, the third limiting hole is an elongated hole. The drive assembly is fixed to the housing assembly. When the drive assembly drives the eccentric assembly to move eccentrically, the eccentric assembly drives the scraping assembly to move. In addition to the first scraping member swinging back and forth and moving up and down under the action of the first limiting part, the scraping assembly can also move back and forth under the reaction force of the eccentric assembly and the action of the third limiting hole. At this time, the scraping assembly as a whole can also undergo displacement relative to the housing assembly, thereby increasing the scraping and scraping range of the scraping assembly and improving its ease of use.

[0031] In one embodiment, the dust box mechanism further includes a sealing member disposed at the dust inlet, the sealing member being movably connected to the housing assembly, and the sealing member at least partially covering the dust inlet.

[0032] The aforementioned dustbin mechanism further includes a sealing element, which is movably connected to the dust inlet of the housing assembly. The sealing element is a dustbin anti-reverse plate. When the cleaning robot performs cleaning and tidying work in the home environment, the roller brush assembly sweeps dust particles to the dust inlet at the front cover of the dustbin mechanism. The fan assembly then draws the dust particles into the receiving cavity, and the dustbin anti-reverse plate prevents the dust particles from overflowing.

[0033] A cleaning robot includes: a body with an installation space; a fan assembly and a roller brush assembly disposed on the body; and a dust box mechanism as described in any of the preceding claims, wherein the dust box mechanism is disposed on the installation space of the body, the fan assembly is disposed opposite to the air outlet, and the roller brush assembly is disposed opposite to the dust inlet.

[0034] The third aspect of this application discloses a cleaning robot that, by adding the aforementioned propulsion mechanism to the dust box mechanism, pulls dust particles from the front end of the dust box mechanism to the rear end, thereby solving the problem of stubborn dust particles blocking the dust inlet of the dust box mechanism and clogging subsequent garbage collection.

[0054] 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.

[0055] 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.

[0056] During routine cleaning and dust collection, the dustbin of a cleaning robot may accumulate and solidify due to a mixture of residue, oil, wastewater, and other dust particles, sometimes even sticking to the dust collection opening. This can prevent the fan from effectively moving these dust particles, posing a risk of clogging subsequent dust collection. Currently, most cleaning robots on the market lack structural designs to mitigate this risk, and the existing practice relies on consumers manually emptying the dustbin using tools. In recent years, the market has seen the emergence of robot vacuums combined with base stations for dust collection, eliminating the hassle of manual emptying and offering a more intelligent and user-friendly experience. However, this very fact makes the aforementioned risk an even more pressing and urgent problem to solve. Therefore, this paper designs a dust particle propulsion mechanism for use in the dustbin of a cleaning robot.

[0057] The propulsion mechanism, dust box mechanism, and cleaning robot of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0058] like Figures 1 to 3 As shown, this embodiment discloses a propulsion mechanism, including: a scraping component 1, which has a first limiting part 101 and is used to scrape dirt from the contact surface; an eccentric component 2, which is adapted to the first limiting part 101 of the scraping component 1; and a driving component 3, which is connected to the eccentric component 2 and is used to drive the eccentric component 2 to reciprocate on the first limiting part 101 to form a first position and a second position. When the eccentric component 2 reciprocates on the first limiting part 101, it drives the scraping component 1 to reciprocate.

[0059] This application discloses a propulsion mechanism 100, in which an eccentric component 2 is connected to a scraping component 1 and a drive component 3. Under the action of the drive component 3, the eccentric component 2 performs an eccentric motion, simultaneously driving the scraping component 1 to perform an eccentric motion. Furthermore, when the eccentric component 2 cooperates with the first limiting part 101 on the scraping component 1, the scraping component 1 can move back and forth and / or up and down relative to the contact surface during the eccentric motion; that is, the scraping component 1 can reciprocate under the action of the first limiting part 101 and the eccentric component 2. The aforementioned propulsion mechanism, through the cooperation of the first limiting part 101, the eccentric component 2, and the drive component 3, enables the scraping component 1 to move back and forth and / or up and down relative to the contact surface, thereby providing technical support for realizing the pushing and scraping action of the scraping component 1 on the contact surface. By applying the aforementioned propulsion mechanism to the dustbin of a cleaning robot, the scraping action of the mechanism's back-and-forth movement can pull dust particles from the front of the dustbin to the rear, solving the problem of stubborn dust particles clogging the dust collection port and hindering subsequent waste collection. Furthermore, the up-and-down movement of the propulsion mechanism prevents the pushed-back dust particles from being pushed back into the dust collection port. This propulsion mechanism is simple in structure, stable, low in cost, and suitable for mass production.

[0060] Optionally, the eccentric component 2 is a combination of at least one or more of the above structures, such as an eccentric wheel, a cam, and an eccentric connecting rod assembly. Figure 8 , Figure 9 As shown, in this embodiment, the eccentric assembly 2 is composed of an eccentric wheel body 21 and a motor bushing 24 that cooperate with each other. An eccentric shaft 22 is provided on one side of the eccentric wheel body 21, and a limiting shaft 23 is provided on the other side of the eccentric wheel body 21. A second connecting hole 2402 is provided on one side of the motor bushing 24. The motor bushing 24 is connected to the limiting shaft 23 of the eccentric wheel body 21 through the second connecting hole 2402.

[0061] Optionally, such as Figure 3 , Figure 8 , Figure 9 As shown, the drive assembly 3 is a drive motor 31. The motor bushing 24 has a first connecting hole 2401 on its side away from the second connecting hole 2402. The first connecting hole 2401 is an eccentric hole. The shaft of the drive motor 31 is connected to the first connecting hole 2401 of the motor bushing 24. The motor bushing 24 connects both the drive motor 31 and the eccentric wheel body 21, which helps improve the stability of the connection between the drive assembly 3 and the eccentric assembly 2, and improves the structural reliability of the propulsion mechanism 100. Furthermore, the shaft of the drive motor 31 can drive the motor bushing 24 to perform eccentric movement, thereby enabling the first scraping member 11 to drive the entire scraping assembly 1 to move up and down, simplifying the structural composition of the propulsion mechanism.

[0062] like Figures 1 to 3As shown, in addition to the features of the above embodiments, this embodiment further defines that: the prying assembly 1 includes a first prying member 11, the first prying member 11 includes a prying body 111 and a cleaning arm 112, one end of the prying body 111 is connected to the cleaning arm 112, the other end of the cleaning arm 112 can abut against the contact surface, and a first limiting part 101 is disposed on the prying body 111.

[0063] The aforementioned propulsion mechanism 100 further defines that: the scraping assembly 1 includes a first scraping member 11, wherein a first limiting part 101 is disposed on the scraping body 111, and a cleaning arm 112 is connected to the scraping body 111. The cleaning arm 112 is used to contact the contact surface and generate a scraping and digging force on the contact surface through the cleaning arm 112, and scrapes the dust particles in the front end of the dust box to the rear end for collection.

[0064] Optionally, a flexible cleaning component or scraper is connected to the side of the cleaning arm 112 near the contact surface, thereby making the contact between the cleaning arm 112 and the contact surface more compact, which is beneficial for improving the cleaning and collection of dirt that has been mixed and solidified by residues, oil stains, or sewage and other dust particles.

[0065] like Figure 3 , Figure 5 , Figure 7 As shown, in this embodiment, the first limiting part 101 is a first limiting hole. The first limiting hole is set on the prying body 111 such that the height of the plane on both sides along the prying direction of the cleaning arm 112 is higher than the height of the plane at the center of the first limiting hole.

[0066] The aforementioned propulsion mechanism 100 is further defined as follows: the first limiting hole is an elongated hole, the first limiting hole is horizontally arranged on the scraping body 111, and the shape of the first limiting hole is such that the height of the plane containing the two side holes of the cleaning arm 112 forming the first and second positions in the scraping movement direction is higher than the height of the plane containing the center position of the first limiting hole. That is, the first limiting hole can be an elongated arc hole, a U-shaped hole, or other arc-shaped structure extending along the scraping movement direction of the cleaning arm.

[0067] In some embodiments, such as Figure 1 , Figure 4 and Figure 5As shown, the drive motor 31 is fixed to the support member. The drive motor 31 is eccentrically engaged with the motor bushing 32 and the eccentric assembly 2, causing the first scraping member 11 to move by driving the motor bushing 32. Specifically, when the motor shaft rotates clockwise, the motor bushing 32 is in an eccentric rotation state (the drive motor shaft and the motor bushing are in the leftmost position), and the first scraping member 11 is in a downward pressing action. During the movement, the cleaning arm on the right side of the first scraping member 11 is also in a moving state. The eccentric column of the eccentric assembly 2 is at the left end, and the cleaning arm of the first scraping member 11 is at the foremost position. Figure 5 The dust particles are located in front of the left end of the eccentric component 2. When the eccentric component 2 rotates counterclockwise by 0° to 90° to 180°, it drives the first scraping component 11 to move to the right, thereby pushing the dust particles to accumulate on the right.

[0068] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, Figure 7 The drive motor 31 is fixed and eccentrically engaged with the motor bushing 32, causing the scraper assembly 1 to move by driving the motor bushing 32. Specifically, when the drive motor shaft rotates clockwise, the motor bushing 32 is in an eccentric rotation state (the drive motor shaft and the motor bushing are in the rightmost position), at which time the first scraper member 11 of the scraper assembly 1 is in a lifting action. Figure 7 During operation, the cleaning arm on the right side of the first pulling component 11 is also in motion. For example... Figure 6 As shown, the eccentric column of the eccentric component 2 is at the right end, and the cleaning arm of the first puller component 11 is at the rear end. Figure 6 The right end (in front of the already scraped dust particles). Rotating counterclockwise 180°~270°~0° will move the scraping component 1 to the left. (In conjunction with...) Figure 7 The first pulling component 11 is in the lifting operation, that is, the pulling component 1 is moving diagonally upward to the left. This avoids pushing the dust particles that have been pushed back back to the dust inlet of the dust box.

[0069] like Figure 2 , Figure 3 As shown, in this embodiment, the prying component 1 further includes a second prying member 12, which is connected to the first prying member 11. A second limiting part 102 is provided on the second prying member 12, which is connected to the first limiting part 101. The eccentric component 2 is adapted to the second limiting part 102.

[0070] The aforementioned propulsion mechanism 100 further defines that the first pulling member 11 and the second pulling member 12 cooperate to form the pulling assembly 1. The second limiting part 102 on the second pulling member 12 is connected to the first limiting part 101 on the first pulling member 11. This allows the eccentric shaft of the eccentric assembly 2 to move within the range defined by the first limiting part 101 and the second limiting part 102. Optionally, the eccentric shaft of the eccentric assembly 2 is adapted to the width inner diameter of the second limiting part 102, and the eccentric shaft can only move in the length direction of the second limiting part 102. The setting of the second limiting part 102 makes the eccentric movement trajectory of the eccentric assembly 2 more stable and the operational reliability of the propulsion mechanism 100 higher. At the same time, when the eccentric assembly 2 is rotating eccentrically, the setting of the second pulling member 12 can effectively drive the entire pulling assembly 1 to move left and right.

[0071] like Figure 2 , Figure 3 , Figure 4 , Figure 6 As shown, in this embodiment, the second limiting part 102 is a second limiting hole, and the eccentric component 2 can move along the length direction of the second limiting hole.

[0072] The aforementioned propulsion mechanism 100 further defines the second limiting part 102 as a second limiting hole. Optionally, the second limiting hole is an elongated hole extending vertically, allowing the eccentric shaft of the eccentric component 2 to be inserted into the second limiting hole, with the eccentric shaft matching the width and inner diameter of the second limiting hole, thereby restricting the eccentric shaft to move up and down along the length of the second limiting hole. The above design is simple, easy to manufacture, and low in cost.

[0073] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the cleaning arm 112 is arranged intersecting with the scraping body 111.

[0074] The aforementioned propulsion mechanism 100 further defines that the cleaning arm 112 and the scraping body 111 are intersecting, thereby cooperating with the structure of the first limiting part 101, which enables the cleaning arm 112 to have a tighter contact with the contact surface and better scraping and scraping performance.

[0075] like Figure 3 , Figure 8 , Figure 9 As shown, in this embodiment, the eccentric assembly 2 includes an eccentric wheel body 21, an eccentric shaft 22, and a limiting shaft 23. The eccentric shaft 22 and the limiting shaft 23 are respectively disposed on opposite sides of the eccentric wheel body 21. The eccentric wheel body 21 is sandwiched between the first pulling member 11 and the second pulling member 12. The eccentric shaft 22 is adapted to the second limiting part 102, and the limiting shaft 23 is adapted to the first limiting part 101.

[0076] The aforementioned propulsion mechanism further specifies that: the eccentric wheel body 21 of the eccentric component 2 is sandwiched between the first pull member 11 and the second pull member 12, and the first pull member 11, the eccentric wheel body 21, and the second pull member 12 are assembled to form a sandwich structure, and the eccentric shaft 22 of the eccentric wheel body 21 cooperates with the second limiting part 102, and the limiting shaft 23 cooperates with the first limiting part 101, so that the assembly between the eccentric component 2 and the first pull member 11 and the second pull member 12 is tighter, which can effectively prevent the eccentric component 2 from shifting during the movement, and the structural stability of the propulsion mechanism is better.

[0077] A dustbin mechanism, used in cleaning robots, such as Figure 1 , Figure 4 and Figure 6 As shown, it includes: a housing assembly 4, which has a receiving cavity 401 inside, and a dust inlet 402 and an air outlet 403 communicating with the receiving cavity 401 on the housing assembly 4; the aforementioned propulsion mechanism, which is disposed inside the receiving cavity 401, and a drive assembly 3 that can drive the scraping assembly 1 to reciprocate between the dust inlet 402 and the side opposite to the dust inlet 402, and the drive assembly 3 can drive the scraping assembly 1 to reciprocate between the top wall and the bottom wall of the receiving cavity 401.

[0078] The second aspect of this application discloses a dustbin mechanism 200, including a housing assembly 4 and the aforementioned propulsion mechanism. By incorporating the aforementioned propulsion mechanism 100, the dustbin mechanism 200 acquires the functions of the propulsion mechanism described above. The propulsion mechanism 100 is disposed within the receiving cavity 401 of the housing assembly 4. The propulsion mechanism 100 draws dust particles from the dust inlet 402 to the rear end, solving the problem of stubborn dust particles clogging the dust inlet of the dustbin mechanism for subsequent waste collection.

[0079] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, the prying component 1 is provided with a third limiting part 103, and a protrusion is formed on the inner wall of the housing component 4. The pushing mechanism is adapted to the protrusion on the inner wall of the housing component 4 through the third limiting part 103.

[0080] The dust box mechanism described above is further defined as follows: a third limiting part 103 is provided on the scraping component 1, specifically, the third limiting part 103 is provided on the first scraping member 11.

[0081] Optionally, the third limiting part 103 is a third limiting hole, and a limiting post is provided on the housing assembly 4. After the limiting post of the housing assembly 4 passes through the third limiting hole, the propulsion mechanism is set on the housing assembly 4.

[0082] Optionally, the third limiting hole is an elongated hole extending horizontally. The drive assembly 3 is fixed to the housing assembly 4. When the drive assembly 3 drives the eccentric assembly 2 to move eccentrically, the eccentric assembly 2 drives the scraping assembly 1 to move. In addition to the first scraping member 11 swinging back and forth and moving up and down under the action of the first limiting part 101, the scraping assembly 1 can also move back and forth under the reaction force of the eccentric assembly 2 and the action of the third limiting hole. At this time, the scraping assembly 1 as a whole can also undergo displacement relative to the housing assembly 4, thereby increasing the scraping and scraping range of the scraping assembly 1 and improving its ease of use.

[0083] like Figure 1 , Figure 4 and Figure 6 As shown, the dust box mechanism in this embodiment also includes a sealing member 5, which is disposed at the dust inlet 402. The sealing member 5 is movably connected to the housing assembly 4, and the sealing member 5 at least partially covers the dust inlet 402.

[0084] The aforementioned dustbin mechanism further includes a sealing element 5, which is movably connected to the dust inlet 402 of the housing assembly 4. The sealing element 5 is a dustbin anti-reverse plate. When the cleaning robot performs home cleaning and tidying work, the roller brush assembly 6 sweeps dust particles to the dust inlet 402 at the front cover of the dustbin mechanism 200. The fan assembly then draws the dust particles into the receiving cavity 401, and the dustbin anti-reverse plate prevents the dust particles from overflowing.

[0085] A cleaning robot, such as Figure 1 , Figure 4 and Figure 6 As shown, it includes: a body with an installation space; a fan assembly and a roller brush assembly 6, which are mounted on the body; and the aforementioned dust box mechanism, which is mounted on the installation space of the body. The fan assembly is positioned opposite the air outlet 403, and the roller brush assembly 6 is positioned opposite the dust inlet 402.

[0086] The third aspect of this application discloses a cleaning robot 300, which, by adding the aforementioned propulsion mechanism 100 to the dust box mechanism 200, pulls dust particles in the front end of the dust box mechanism 200 to the rear end, thereby solving the problem of stubborn dust particles blocking the dust inlet of the dust box mechanism for subsequent garbage collection.

[0087] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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, they should be considered to be within the scope of this specification.

[0088] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
