Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly relates to a floor sweeping robot and a dust collection base thereof. Background Art

[0002] In existing floor sweeping robots, the HEPA used for filtering dust on the floor sweeper (or called the main body) is difficult to be completely cleaned. Especially, dust accumulates at some corners of the HEPA because the dust cannot be cleaned, which leads to the blockage of the HEPA ventilation and affects the dust suction efficiency. The existing cleaning method is mainly manual cleaning. Manual cleaning is not only troublesome and inconvenient, but also easy to dirty hands and tools.

[0003] The above content is only used to assist in understanding the technical solution of the invention, and does not represent an admission that the above content is prior art. Summary of the Invention

[0004] The main object of the present invention is to propose a dust collection base, aiming to solve the technical problem that the HEPA on the floor sweeper in some existing floor sweeping robots cannot be conveniently cleaned.

[0005] To achieve the above object, the dust collection base proposed by the present invention includes a base body and a knocking assembly. A HEPA cleaning position is provided on the surface of the base body, and the HEPA cleaning position is used for placing the HEPA assembly to be cleaned. The knocking assembly is disposed close to the HEPA cleaning position and includes a knocking member and a driving member for driving the knocking member to reciprocate. The knocking member is used for knocking the HEPA assembly during reciprocating movement.

[0006] In one embodiment, the HEPA cleaning position is a cleaning groove, and knocking holes are provided on the groove wall of the cleaning groove; the knocking assembly is installed in the base body, and when the knocking member is driven by the driving member, it makes a reciprocating sliding movement and can extend into the cleaning groove through the knocking holes.

[0007] In one embodiment, the knocking member has opposite first and second ends. The first end is used for knocking the HEPA assembly, and an elastic member is provided at the second end; one end of the elastic member abuts against the second end, and the other end abuts against the base body. When the driving member drives the knocking member away from the cleaning groove, the elastic member is compressed by the knocking member.

[0008] In one embodiment, the driving member includes a motor and an eccentric wheel connected to the output shaft of the motor. A first pushing structure is convexly provided on the outer periphery of the eccentric wheel. The first pushing structure has a first rotation area and a second rotation area as the eccentric wheel rotates; in the first rotation area, the first pushing structure abuts against the knocking member and pushes the knocking member away from the cleaning groove; in the second rotation area, the first pushing structure disengages from the abutment with the knocking member.

[0009] In one embodiment, a second pushing structure protrudes from the surface of the knocking member facing the eccentric wheel. In the first rotation region, the first pushing structure abuts against the second pushing structure and pushes the knocking member by pushing the second pushing structure.

[0010] In one embodiment, a first air duct is further provided in the seat body. One end of the first air duct is connected to the cleaning groove, and the other end is used to be connected to a dust bag.

[0011] In one embodiment, a dust bag installation groove, a dust extraction fan and a second air duct are further provided in the seat body. A dust bag for collecting dust is installed in the dust bag installation groove, and the air inlet of the dust extraction fan is communicated with the dust bag installation groove. One end of the second air duct is connected to the dust bag, and the other end is used to be correspondingly connected to the dust suction port of the floor sweeper. One end of the first air duct is connected to the cleaning groove, and the other end is connected to the second air duct.

[0012] In one embodiment, the second air duct is divided into a first section and a second section. The first section is connected to the dust bag; the first section, the second section and the first air duct are connected through a three-way pipe, and a switching switch is further provided in the three-way pipe; the switching switch can open the second section while closing the first air duct, and can close the second section while opening the first air duct.

[0013] The present invention further provides a floor sweeping robot, which includes a floor sweeper and a dust collection base. The floor sweeper is used to move on the ground and clean the ground, and a HEPA component for filtering dust is installed in the floor sweeper. The dust collection base is used to collect the dust in the floor sweeper and clean the HEPA component, and includes:

[0014] A seat body, on the surface of which there is a HEPA cleaning position for placing the HEPA component to be cleaned; and,

[0015] A knocking component, which is arranged close to the HEPA cleaning position and includes a knocking member and a driving member for driving the knocking member to reciprocate. The knocking member is used to knock the HEPA component when reciprocating.

[0016] In one embodiment, the HEPA component includes a HEPA body and a HEPA bracket. The HEPA body is installed on the HEPA bracket, and the knocking member knocks the HEPA bracket when reciprocating.

[0017] The dust collection base of the present invention is provided with a HEPA cleaning position and a knocking component on its base body. When it is necessary to clean the HEPA component, only the HEPA component needs to be placed in the HEPA cleaning position, and the HEPA component can be repeatedly knocked by the knocking component. It can be understood that when the knocking component knocks the HEPA component, each position of the HEPA component will vibrate, thereby shaking off the dust at each position on it. This not only realizes the automatic cleaning of the HEPA component, that is, no manual cleaning is required, but also makes the HEPA component cleaner, solving the technical problem that it is difficult to completely and conveniently clean the HEPA component.

[0030] The realization, functional features, and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. Detailed Embodiments

[0031] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, these directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, these "first", "second", etc. descriptions are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or the solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0033] The present invention provides a floor sweeping robot, as Figure 1 shown. The floor sweeping robot includes a floor sweeper (not shown) and a dust collector 10. Among them, the floor sweeper is used to move on the ground and clean the ground. Specifically, a suction motor and a dust box are mainly installed in the floor sweeper. The suction motor is respectively connected to the dust box and the air outlet on the floor sweeper, and the dust box is connected to the suction port on the floor sweeper. When the floor sweeper is performing cleaning work, the suction motor rotates at a high speed, causing a certain vacuum in the dust box. Then, under the action of the pressure difference, dust, garbage, etc. on the ground are sucked into the dust box through the suction port.

[0034] Generally, a dust bag is provided in the dust box. The dust bag is breathable and can filter dust, and thus can be used to collect dust and garbage, and prevent dust and garbage from being sucked into the suction fan. In order to prevent the dust bag from bursting and causing dust to enter the suction fan, or to prevent finer dust particles from passing through the dust bag and being re-discharged into the air. A HEPA assembly 100 (HEPA, High Efficiency Particulate Air Filter) is also provided between the suction fan and the dust box and / or at the air outlet of the floor sweeper, so as to be able to filter dust and suspended matter with smaller particle sizes and avoid secondary pollution during the cleaning process of the floor sweeping robot.

[0035] After the floor sweeper finishes the cleaning work or during the cleaning process, the dust and garbage collected in its dust box need to be cleaned in time to avoid affecting the normal operation of the floor sweeper. Therefore, the dust collection base 10 is mainly used to automatically collect the dust in the dust box of the floor sweeper. Specifically, please refer to Figure 1 and Figure 8 , a dust extraction fan 60, a dust bag and a second air duct 70 are installed in the dust collection base 10, a dust extraction port 110 is formed on the surface of the dust collection base, and the dust extraction port 110 is communicated with the dust bag through the second air duct 70.

[0036] When it is necessary to clean the dust and garbage in the dust box of the floor sweeper, the floor sweeper moves to the dust collection base 10 and makes its dust suction port correspondingly connected to the dust extraction port 110 on the dust collection base 10. Then the dust extraction fan 60 sucks air, so that the dust in the dust box of the floor sweeper is sucked into the dust bag on the dust collection base 10 through the second air duct 70, realizing the automatic cleaning of the floor sweeper.

[0037] Of course, some dust collection bases 10 can also charge the floor sweeper while cleaning the floor sweeper. For example, in this embodiment, as Figure 1 shown, a charging terminal 120 protrudes from the dust collection base 10, and the floor sweeper can automatically move to the dust collection base 10 for automatic charging.

[0038] Similarly, the HEPA assembly 100 on the floor sweeper also needs to be cleaned in time to avoid affecting the air suction efficiency of the floor sweeper. The existing cleaning method is mainly manual cleaning. Manual cleaning is not only more troublesome and inconvenient, but also easily dirties hands and tools. Therefore, the present invention also proposes a dust collection base 10 to solve the above technical problems.

[0039] It should be noted that the dust collection base 10 proposed by the present invention can be used not only to clean the HEPA assembly 100 on the floor sweeper, but also to clean the HEPA assembly 100 on other types of vacuum cleaners, such as the HEPA assembly 100 on a handheld vacuum cleaner, etc. In addition, it can also be used to clean the HEPA assembly 100 on other non-vacuum cleaner devices that are also used to filter dust, and no specific limitation is made here.

[0040] In the embodiment of the present invention, as Figures 1 to 5 shown, the dust collection base 10 includes a base body 20 and a knocking assembly 30. Among them, as Figure 1 shown, a HEPA cleaning position 21 is provided on the surface of the base body 20, and the HEPA cleaning position 21 is used to place the HEPA assembly 100 that needs to be cleaned. Specifically, the HEPA installation position can be formed by structures such as a groove, a clamping bracket, a fixing boss, etc., and only needs to be able to place and fix the HEPA assembly 100. For example, in one embodiment, as Figure 2As shown, the Hepa cleaning position 21 is a cleaning groove 211, and the shape, size and depth of the cleaning groove 211 are all adapted to the Hepa assembly 100. In this way, when the Hepa assembly 100 needs to be cleaned, the Hepa assembly 100 can be directly placed into the cleaning groove 211, which is very convenient for the placement and positioning of the Hepa assembly 100.

[0041] In addition, in order to better collect the dust, particles, etc. cleaned from the Hepa assembly 100, a dust bag, a dust box, etc. can also be provided on the Hepa cleaning position 21. At the same time, in order to prevent the dust or particles on the Hepa assembly 100 from drifting into the indoor air during the cleaning process of the Hepa assembly 100, an outer cover can be put on the outside of the Hepa cleaning position 21 during cleaning, or (when the Hepa cleaning position 21 is a groove structure) a sealing cover can be covered, or the dust can be sucked into the dust bag or dust box by a dust extraction fan 60, etc., and the specific setting can be determined according to the actual situation.

[0042] As Figure 2 and Figure 5 As shown, the knocking assembly 30 is arranged close to the Hepa cleaning position 21 and includes a knocking member 31 and a driving member 32 for driving the knocking member 31 to reciprocate. Among them, the driving member 32 can be a motor 321, a hydraulic device, a magnetic attraction device, etc., and the knocking member 31 can be a rod-shaped, plate-shaped, block-shaped or combined structure, etc. For example, in this embodiment, the knocking member 31 is in a rod-shaped structure, which is not only convenient for being driven to move, but also can ensure the knocking force. Of course, the specific structural form can be set according to actual needs.

[0043] The knocking member 31 is used to knock the Hepa assembly 100 during reciprocating motion. Among them, the motion form of the knocking member 31 can be rotation, sliding, etc. When knocking the Hepa assembly 100, the side surface, end surface, etc. of the Hepa assembly 100 can be knocked, and no specific limitation is made here.

[0044] For example, in an embodiment, as Figure 2 shown, the Hepa cleaning position 21 is a cleaning groove 211, and a knocking hole 212 is provided on the groove wall of the cleaning groove 211; the knocking assembly 30 is installed in the seat body 20, and when the knocking member 31 is driven by the driving member 32, it makes a reciprocating sliding motion and can pass through the knocking hole 212 and extend into the cleaning groove 211. It can be understood that such a setting not only enables the knocking assembly 30 to be hidden in the seat body 20 to avoid being knocked by foreign objects or affecting the appearance of the dust collection seat 10, but also enables the knocking member 31 not to occupy too much movement space and avoid increasing the overall volume of the dust collection seat 10.

[0045] It should be noted that to ensure the smooth movement of the knocking member 31, a sliding groove can be provided in the seat body 20, and the knocking member 31 can be slidably installed in the sliding groove to prevent the knocking member 31 from deviating in position during movement.

[0046] In addition, the knocking assembly 30 and the knocking hole 212 are provided on the side of the cleaning groove 211, which can be the left side, right side, front side, rear side, etc. Specifically, it can be set according to the actual structure of the dust collection seat 10. For example, when setting, it can be selected based on principles such as convenient installation and small occupied space.

[0047] In summary, it can be understood that when the HEPA assembly 100 needs to be cleaned, only the HEPA assembly 100 needs to be placed in the cleaning groove 211, and then the knocking assembly knocks on the HEPA assembly. When the knocking assembly 30 knocks on the HEPA assembly 100, each position of the HEPA assembly 100 will vibrate, thereby shaking off the dust at each position on it. This not only realizes the automatic cleaning of the HEPA assembly 100, that is, no manual cleaning is required, but also makes the HEPA assembly 100 cleaner, solving the technical problem that the HEPA assembly 100 is difficult to be completely and conveniently cleaned.

[0048] For the specific manner in which the driving member 32 drives the knocking member 31 to reciprocate, there are various options. For example, the driving member 32 can be a driving member 32 such as a cylinder or a hydraulic cylinder with a piston rod. The knocking member 31 can be connected to the piston rod and reciprocally slide under the drive of the piston rod, thereby knocking on the HEPA assembly 100.

[0049] Another example is that the driving member 32 can be a magnetic attraction type driving member 32, and the knocking member 31 is a metal member or a magnetic member that can be magnetically attracted. At this time, only by controlling the magnetic attraction direction of the magnetic attraction type driving member 32 or controlling the presence or absence of the magnetic attraction force, the knocking member 31 can be repeatedly magnetically attracted and released, thereby realizing the reciprocating movement of the knocking member 31.

[0050] Still another example is that in one embodiment, as Figure 5 and Figure 7 shown, the knocking member 31 has a rod-shaped structure and has opposite first end 311 and second end 312. The first end 311 is used to knock on the HEPA assembly 100, and an elastic member 33 is provided at the second end 312. The elastic member 33 can specifically be a spring. One end of the elastic member 33 abuts against the second end 312, and the other end abuts against the seat body 20. When the driving member 32 drives the knocking member 31 away from the cleaning groove 211, the elastic member 33 is compressed by the knocking member 31.

[0051] When the elastic member 33 is compressed to a preset degree of deformation, the driving member 32 can release the connection or abutment with the knocking member 31, thereby releasing the compression of the elastic member 33 by the knocking member 31. At this time, the elastic member 33 recovers its elastic deformation and pushes the knocking member 31 towards the cleaning groove 211 until the knocking member 31 impacts the Hepa assembly 100 in the cleaning groove 211. Then the driving member 32 drives the knocking member 31 away from the cleaning groove 211 again, causing the knocking member 31 to compress the elastic member 33 again, and finally releasing the knocking member 31 again. By repeating this cycle, the reciprocating motion of the knocking member 31 is achieved.

[0052] It can be understood that the solution of realizing the reciprocating motion of the knocking member 31 through the elastic member 33 is not only simple and feasible but also reduces energy consumption. In order to avoid the situation where the elastic member 33 disengages from the abutment with the knocking member 31 during the telescopic process, in this embodiment, as Figure 7 shown, a positioning structure such as a positioning boss, a positioning groove, etc. is also provided at the second end 312. The elastic member 33 is a hollow spring structure and is sleeved outside the positioning structure or embedded in the positioning structure when abutting against the knocking member 31, ensuring the abutment stability between the elastic member 33 and the knocking member 31.

[0053] Meanwhile, the force of the knocking member 31 knocking on the Hepa assembly 100 can be controlled by the compression amount of the elastic member 33. In this embodiment, the knocking force of the knocking member 31 is not less than 70 g and not more than 150 g, such as 70 g, 80 g, 100 g, 125 g, 150 g, etc. If the knocking force is less than 70 g, it may result in insufficient cleaning of the Hepa assembly 100, and it is difficult to shake off the dust in some corners of the Hepa assembly 100. If the knocking force is greater than 150 g, the Hepa assembly 100 may be damaged. Therefore, when the knocking force is not less than 70 g and not more than 150 g, it can not only ensure the cleaning of the Hepa assembly 100 but also avoid damaging the Hepa assembly 100.

[0054] Of course, the specific knocking force can also be set according to the specifications and dust accumulation degree of the Hepa assembly 100 to be cleaned.

[0055] In addition, it should be noted that when adopting the solution of the elastic member 33, the driving member 32 cooperating with the elastic member 33 can still adopt the above-mentioned telescopic driving member and magnetic attraction driving member, or an electric motor 321 can also be adopted. When the driving member 32 adopts the electric motor 321, the rotational motion of the electric motor 321 is converted into the linear motion of the knocking member 31 through a transmission member, and the connection or abutment with the knocking member 31 is released when needed.

[0056] For example, in one embodiment, as Figure 6 or Figure 7As shown, the driving member 32 includes a motor 321 and an eccentric wheel 322 connected to the output shaft of the motor 321. A first pushing structure 3221 protrudes from the outer periphery of the eccentric wheel 322. The first pushing structure 3221 has a first rotation area and a second rotation area as the eccentric wheel 322 rotates; within the first rotation area, the first pushing structure 3221 abuts against the knocking member 31 and pushes the knocking member 31 away from the cleaning groove 211; within the second rotation area, the first pushing structure 3221 disengages from the abutment with the knocking member 31.

[0057] In this embodiment, the first pushing structure 3221 makes a circular motion around the rotation axis of the eccentric wheel 322 (or the output shaft of the motor 321). Its 360° rotation area can be divided into a first rotation area and a second rotation area. At least part of the structure of the knocking member 31 is located within the first rotation area. Therefore, when the first pushing structure 3221 rotates into the first rotation area, the first pushing structure 3221 will abut against the knocking member 31 and push the knocking member 31 to slide away from the cleaning groove 211. While the knocking member 31 slides away from the cleaning groove 211, it also gradually exits the first rotation area. When all of its structure is outside the first rotation area, the first pushing structure 3221 disengages from the abutment with the knocking member 31 and enters the second rotation area. After the knocking member 31 disengages from the abutment with the first pushing structure 3221, it will slide towards the cleaning groove 211 under the elastic force of the elastic member 33 and knock on the HEPA assembly 100, and at the same time at least part of its structure will also return to the first rotation area. When the first pushing structure 3221 rotates into the first rotation area again, it will push the knocking member 31 again. Repeating this cycle, the reciprocating sliding of the knocking member 31 is achieved.

[0058] It can be understood that the driving member 32 structure composed of the motor 321 and the eccentric wheel 322 can realize the automatic connection and automatic release of the knocking member 31. The whole process only needs to control the rotation of the motor 321, which is not only simple in structure but also convenient to control. The type, rotation speed of the motor 321, and the size and eccentricity of the eccentric wheel 322 are not specifically limited here and can be selected according to actual needs.

[0059] For example, in this embodiment, the rotation speed of the motor 321 is approximately 80 - 100 RPM (revolutions per minute), such as 90 RPM. If it rotates too fast, it may start to push the knocking member 31 again when the knocking member 31 is still under the elastic force, thus affecting the sliding and knocking of the knocking member 31; if it rotates too slowly, the cleaning efficiency will be affected. Therefore, by controlling the rotation speed of the motor 321 within 80 - 100 RPM, and further controlling the cleaning time within 15 seconds to 20 seconds, both the cleaning effect and the cleaning efficiency are ensured.

[0060] In addition, it should be noted that there are various specific ways to make at least part of the structure of the striking member 31 extend into the first rotation area of the first pushing structure 3221. For example, the surface of the striking member 31 facing the eccentric wheel 322 can be set as an inclined surface, and this inclined surface is located in the first rotation area. Then, the first pushing structure 3221 can push the entire striking member 31 to slide by pushing this inclined surface, and can automatically disengage from the abutment with this inclined surface when this inclined surface completely exits the first rotation area.

[0061] For another example, in an embodiment, as Figure 6 or Figure 7 shown, a second pushing structure 313 protrudes from the surface of the striking member 31 facing the eccentric wheel 322. In the first rotation area, the first pushing structure 3221 abuts against the second pushing structure 313 and pushes the striking member 31 by pushing the second pushing structure 313. One end of the first pushing structure 3221 away from the eccentric wheel 322 is arranged in an arc shape, and / or one end of the second pushing structure 313 away from the striking member 31 is arranged in an arc shape. Thus, it is ensured that the first pushing structure 3221 and the second pushing structure 313 can smoothly abut automatically and disengage from the abutment automatically.

[0062] In an embodiment, as Figure 4 and Figure 8 shown, a first air duct 40 is further provided in the base body 20. One end of the first air duct 40 is connected to the cleaning groove 211, and the other end is used to be connected to a dust bag. After the dust on the HEPA assembly 100 is shaken off, the dust can be directly sucked into the dust bag through the first air duct 40, realizing the automatic cleaning and collection of the dust after it is shaken off from the HEPA assembly 100. Thus, it is not necessary to manually handle the shaken-off dust, and it is avoided that the shaken-off dust floats back into the room and causes secondary pollution.

[0063] In addition, some dust or particles on the HEPA assembly 100 adhere to the HEPA relatively firmly. When the knocking assembly 30 knocks the HEPA assembly 100, only the relatively firmly adhered dust or particles can be loosened, but they do not fall off. Therefore, through the suction of the first air duct 40, the dust particles that are only loosened but do not fall off can also be effectively sucked away from the HEPA assembly 100, making the cleaning of the HEPA assembly 100 cleaner and realizing the deep cleaning of the HEPA assembly 100.

[0064] It should be noted that a dust bag is originally provided in the dust collection base 10 (in the dust bag installation groove 50, the dust bag installation groove 50 can be referred to Figure 1 ), and this dust bag is used to collect the dust collected in the dust box of the floor sweeper. The dust bag connected to the first air duct 40 can be an additionally provided dust bag, or in order to simplify the structure and subsequent operations, the first air duct 40 can be connected to the dust collection bag originally provided in the dust collection base 10.

[0065] For example, in one embodiment, Figure 8 As shown, the seat body 20 is further provided with a dust bag installation slot 50, a dust extraction fan 60 and a second air duct 70. A dust bag for collecting dust is installed in the dust bag installation slot 50, and the air inlet of the dust extraction fan 60 is connected to the dust bag installation slot 50. One end of the second air duct 70 is connected to the dust bag, and the other end is used to be connected to the dust suction port of the sweeper. One end of the first air duct 40 is connected to the cleaning slot 211, and the other end is connected to the second air duct 70.

[0066] It can be understood that the present embodiment utilizes the dust extraction fan 60, dust bag and second air duct 70 originally provided in the dust collecting base 10, and by connecting the first air duct 40 to the second air duct 70, the dust cleaned from the Hypa assembly 100 can be directly sucked into the dust bag. Under the action of suction, it can be ensured that the dust cleaned from the Hypa assembly 100 will not float back into the room and cause secondary pollution. In addition, there is no need to set up other dust bags for collecting dust in the first air duct 40, which greatly simplifies the structure of the dust collecting base 10.

[0067] In one embodiment, if Figure 8 As shown, the second air duct 70 is divided into a first section 71 and a second section 72, the first section 71 is connected to the dust bag; the first section 71, the second section 72 and the first air duct 40 are connected via a three-way pipe 80, and a switching switch 90 is also provided in the three-way pipe 80; the switching switch 90 can open the second section 72 while closing the first air duct 40, and can close the second section 72 while opening the first air duct 40.

[0068] In this embodiment, when it is necessary to clean the dust and garbage in the dust box of the sweeper, the switching switch 90 closes the first air duct 40 and opens the second section 72 of the second air duct 70, so that the first section 71 and the second section 72 are connected, that is, the entire second air duct 70 is turned on, thereby being able to collect the dust in the dust box of the sweeper while preventing the dust from the first air duct 40 from floating back into the room.

[0069] When it is necessary to clean the dust on the Hypa component 100, the switching switch 90 opens the first air duct 40 and closes the second section 72 of the second air duct 70, so that the first air duct 40 and the first section 71 of the second air duct 70 are connected, thereby collecting the dust shaken off the Hypa component 100 while preventing the dust from floating back into the room from the second section 72 of the second air duct 70.

[0070] The floor cleaning robot proposed by the present invention includes a floor cleaning machine and a dust collecting base 10. The specific structure of the dust collecting base 10 refers to the above-mentioned embodiments. Since this floor cleaning robot adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated one by one here.

[0071] In one embodiment, as Figure 3 and Figure 5 shown, the HEPA assembly 100 includes a HEPA body 101 and a HEPA bracket 102. The HEPA body 101 is installed on the HEPA bracket 102, and the knocking member 31 knocks the HEPA bracket 102 when reciprocating.

[0072] Specifically, in this embodiment, both the HEPA body 101 and the HEPA bracket 102 are in a square block structure, and the HEPA bracket 102 is provided with an installation groove for installing the HEPA body 101. When the HEPA body 101 is installed in the installation groove, its four side surfaces are in contact with the groove walls of the installation groove. In this way, when the knocking assembly 30 knocks the HEPA bracket 102, the HEPA bracket 102 can transmit the vibration to the HEPA body 101 to realize the cleaning of the HEPA body 101. At the same time, it can avoid the situation that the HEPA body 101 is damaged or deformed when the knocking member 31 directly knocks the HEPA body 101.

[0073] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
