Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to an inlet regulating module and a cleaning device. Background Art

[0002] Existing sweeping robots can be mainly divided into two types according to different application scenarios: indoor (household) sweeping robots and outdoor sweeping robots.

[0003] Among them, the distance between the cleaning roller brush and the garbage collection component of the indoor sweeping and vacuuming robot is usually small, only about 5 mm. The solid garbage that can be cleaned by this type of sweeping and vacuuming robot is mostly garbage and dust particles with a smaller overall size. When encountering solid garbage of larger size, the solid garbage may be pushed or stuck between the cleaning roller brush and the garbage collection component, which not only fails to complete the collection of larger garbage, but also affects the cleaning effect of small-sized garbage.

[0004] Although the distance between the cleaning roller brush and the garbage collection component of the outdoor sweeping robot is relatively large, it needs to be used in conjunction with a large suction motor. It has disadvantages such as high energy consumption and high noise during use. It cannot effectively collect small-sized garbage such as dust and is not suitable for indoor use.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0042] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0043] When using automatic cleaning devices such as sweeping robots to clean, there may be a variety of solid wastes of different sizes on the ground, such as large paper balls, orange peels, water bottle caps, etc. with a structure size of about 10mm to 40mm; small paper scraps, melon seeds, peanut shells, cigarette butts, cigarette ashes, etc. with an overall size of less than 10mm. Since existing cleaning devices cannot clean and collect wastes of various structure sizes, the cleaning effect is poor.

[0044] In order to solve the technical problem that the cleaning device in the prior art cannot simultaneously clean and collect garbage of multiple different structural sizes, the present application provides an entrance adjustment module, which can adjust the distance between the cleaning component 2 and the collecting component 1, so that the size of the entrance formed between the bottom edge of the cleaning component 2 and the guide member 11 of the collecting component 1 changes, thereby adapting to the cleaning and collection of solid garbage of different structural sizes, which is beneficial to improving the cleaning effect of the cleaning device.

[0045] See also Figures 1 to 9 In a first aspect, an embodiment of the present application provides an inlet adjustment module, including a collecting component 1, a cleaning component 2 and an adjustment component 3. The collecting component 1 is used to collect the solid waste gathered during the cleaning process. The collecting component 1 includes a guide member 11 arranged along the bottom edge thereof, so that the waste can smoothly enter the interior of the collecting component 1 along the guide member 11. Figure 4 and Figure 5 shown.

[0046] The cleaning component 2 is arranged opposite to the collecting component 1 and is used to push the garbage toward the collecting component 1. The bottom edge of the cleaning component 2 and the guide member 11 form an entrance of the collecting component 1. Figure 1 , Figure 4 and Figure 5 As shown, after the solid waste is pushed by the cleaning component 2, it moves along Figure 4 or Figure 5 Move from right to left in the process and follow the guide member 11 to enter the interior of the collecting assembly 1 .

[0047] The adjusting component 3 is connected between the collecting component 1 and the cleaning component 2. The adjusting component 3 drives the cleaning component 2 to move relative to the guide member 11, thereby adjusting the size of the entrance, so that solid waste of different structural sizes enters the collecting component 1 from the entrance.

[0048] It should be noted that in order to adjust the size of the entrance, the adjusting component 3 can drive the cleaning component 2 to slide in an inclined upward direction, or can drive the cleaning component 2 to swing relative to the collecting component 1, thereby changing the distance between the guide 11 and the bottom edge of the cleaning component 2, so that solid waste of different sizes can enter the collecting component 1 through the entrance.

[0049] In some embodiments of the present application, a mounting bracket 13 for connecting with the adjusting component 3 is provided on the top of the collecting component 1, which can provide an installation space for the cleaning component 2 to slide upward or rotate upward.

[0050] In the above embodiment, if the installation of the cleaning component 2 is achieved through a guide rail, in order to ensure the sliding smoothness of the cleaning component 2, guide rails and their driving components need to be provided on both sides of the mounting frame 13 to connect with the cleaning component 2, which will result in a large number of parts on both sides of the mounting frame 13 and a large structural size.

[0051] In order to avoid the above problems, the present application preferably uses a method of driving the cleaning component 2 to rotate relative to the collecting component 1 to adjust the size of the inlet. Figure 1 , Figure 2 , Figure 4 and Figure 5 The adjustment component 3 includes a swing arm 31 and a swing arm driving component 32. One end of the swing arm 31 is connected to the cleaning component 2, and the other end of the swing arm 31 is hinged to the collecting component 1. The swing arm driving component 32 drives the swing arm 31 to rotate relative to the collecting component 1, providing power for the rotation of the swing arm 31. When the swing arm 31 rotates relative to the collecting component 1 around the hinge between the swing arm 31 and the collecting component 1, the cleaning component 2 also moves synchronously, thereby realizing the inlet size adjustment, such as Figure 4 and Figure 5 shown.

[0052] In some embodiments of the present application, the swing arm member 31 includes an H-shaped structure, and can be hinged to the two sides of the mounting frame 13 through the two sides of the H-shaped structure, which is beneficial to improving the connection reliability between the adjustment component 3 and the mounting frame 13.

[0053] It should be noted that the rotation of the swing arm 31 relative to the collection assembly 1 can be achieved in a variety of ways. In some embodiments of the present application, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The swing arm drive assembly 32 includes a connected rotating drive member 321 and a cam 322. The rotating drive member 321 and the cam 322 are both mounted on the mounting frame 13 at the top of the collection assembly 1. The rotating drive member 321 drives the cam 322 to rotate relative to the mounting frame 13. The cam 322 has an abutting surface 3221 for contacting the swing arm member 31. When the abutting surface 3221 of the cam 322 contacts the swing arm member 31, the swing arm member 31 can be pushed to rotate relative to the collection assembly 1. Specifically, when the cam 322 moves along the Figure 4 Rotate counterclockwise to Figure 5During the state shown, the swing arm 31 contacts the abutment surface 3221 of the cam 322. Under the push of the abutment surface 3221, the swing arm 31 rotates counterclockwise around the hinge between it and the collecting assembly 1, so that the cleaning assembly 2 moves upward as a whole, and the inlet size becomes larger. Figure 4 If the counterclockwise rotation in the middle continues, the entrance size will gradually increase, and then gradually decrease, and such a reciprocating cycle can realize the periodic change of the entrance size. When the entrance size is small, small-sized garbage can be efficiently cleaned and collected. When the entrance size is large, large-sized garbage can enter the interior of the collection component 1 through the entrance, and intermittent collection of large-sized garbage can be realized while ensuring the cleaning effect of small-sized garbage.

[0054] In other embodiments of the present application, the swing arm drive assembly 32 includes a telescopic part, which can be a linear actuator such as a cylinder or a hydraulic cylinder. The two ends of the telescopic part are respectively hinged to the collection assembly 1 and the swing arm part 31. When the telescopic part is extended or retracted, the swing arm part 31 can rotate around the hinge with the collection assembly 1, thereby also realizing the adjustment of the inlet size.

[0055] In some other embodiments of the present application, the swing motor may be directly connected to the rotating shaft of the swing arm member 31 , so as to realize the reciprocating swing of the swing arm member 31 .

[0056] It should be noted that in the above embodiment, if the swing arm 31 is driven to swing by the telescopic member or the swing motor, the airflow or hydraulic oil inside the telescopic member and the swing motor needs to be frequently reversed, which will affect the service life of the telescopic member, the swing motor and the valve member that controls the reversal, resulting in poor reliability of the inlet regulating module. When the cam 322 is used to drive the swing arm 31 to swing, the rotary drive member 321 can always rotate in one direction to make the swing arm 31 swing back and forth, which is conducive to ensuring the service life of the rotary drive member 321. Therefore, the present application preferably uses the cam 322 and the rotary drive member 321 to drive the swing arm 31 to swing.

[0057] In some embodiments of the present application, the cam 322 and the swing arm 31 are both made of hard chrome-plated steel, which can improve the hardness and wear resistance of the surface of the cam 322 and the swing arm 31, which is beneficial to increasing the service life of the cam 322 and the swing arm 31.

[0058] As a specific embodiment of this application, please refer to Figure 4 and Figure 5When there is no contact between the cam 322 and the swing arm 31, the inlet size is the smallest, the minimum spacing L1 between the collecting assembly 1 and the cleaning assembly 2 is 5 mm, and the bottom edge of the cleaning assembly 2 is close to the guide 11, so small-sized solid waste can be lifted and smoothly pushed into the guide 11 and the collecting assembly 1. When the cam 322 contacts the swing arm 31, the inlet size gradually increases, and the maximum spacing L2 between the collecting assembly 1 and the cleaning assembly 2 is 25 mm, so that large-sized waste can smoothly enter the collecting assembly 1 through the inlet.

[0059] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The collecting assembly 1 includes a garbage box 12, and a guide member 11 is arranged at a bottom edge of the opening of the garbage box 12 and tilted downward. Under the pushing action of the cleaning assembly 2, the solid garbage can smoothly enter the garbage box 12 along the tilt direction of the guide member 11. Figure 4 and Figure 5 Specifically, the guide member 11 has an inclination angle of 45°, so that the guide member 11 can scoop up the solid waste in front of it, and under the pushing action of the cleaning assembly 2, the solid waste can enter the garbage box 12 along the inclined surface of the guide member 11. In order to achieve the installation and positioning of the guide member 11, the bottom edge of the garbage box 12 has a slope structure for placing the guide member 11.

[0060] The top of the trash box 12 is fixedly connected to the mounting frame 13, so that the swing arm 31 can swing above the trash box 12, thereby adjusting the size of the bottom entrance of the trash box 12. In order to ensure that the solid waste collected by the cleaning assembly 2 can enter the trash box 12, the lateral opening size of the trash box 12 is larger than the lateral size of the cleaning assembly 2. Figure 3 shown.

[0061] In some embodiments of this application, please refer to Figure 4 and Figure 5 The guide member 11 is a sheet-like flexible member, which can be completely fitted with the ground through the elastic deformation of the guide member 11. It is prevented that the solid garbage moves to the rear of the garbage box 12 through the gap between the guide member 11 and the ground, and cannot be effectively collected.

[0062] It should be noted that the sheet-like flexible parts can be made of materials such as silicone and rubber. They have elastic deformation capabilities and certain structural strength, and can effectively block solid waste.

[0063] In some embodiments of this application, please refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The cleaning assembly 2 includes a detachable roller 21. When the roller 21 is damaged, the roller 21 can be easily replaced, which is beneficial to extending the overall service life of the inlet adjustment module and the cleaning device.

[0064] The outer surface of the drum 21 has multiple flexible sheet structures 211, which can fit against the ground when cleaning garbage, which is conducive to pushing solid garbage toward the garbage box 12, preventing garbage from leaking through the gap between the drum 21 and the ground, and preventing hair and thin ropes from being entangled on the drum 21, which is conducive to improving the cleaning effect of the drum 21.

[0065] The flexible sheet structure 211 is arranged on the outer peripheral surface of the drum 21 in a wave shape, a spiral shape or a straight line shape, and can block and push the solid waste during the cleaning process.

[0066] As a specific embodiment of this application, please refer to Figure 6 and Figure 7 The drum 21 includes a drum body 212, on which four flexible sheet structures 211 are arranged, so that the distance between adjacent flexible sheet structures 211 can be made larger, so that large-sized solid waste can enter the space formed by two adjacent flexible sheet structures 211, which is convenient for cleaning large-sized solid waste. Each flexible sheet structure 211 has a width of 15 mm to 20 mm and is arranged in a wave shape on the outer peripheral surface of the drum body 212. As the drum body 212 rotates, multiple sheet-like flexible structures push or lift up the solid waste, so as to clean the solid waste. Specifically, the flexible sheet structure 211 can be made of materials such as silicone and rubber.

[0067] A transmission part 213 is provided at one end of the drum body 212 for connecting with the drum driving assembly 24 to realize the rotation of the drum 21 .

[0068] In some embodiments of this application, please refer to Figure 4 , Figure 5 and Fig. 9 The cleaning assembly 2 includes a roller bin 22 detachably connected to the roller 21, which can facilitate the replacement of the roller 21. The swing arm 31 of the adjustment assembly 3 is connected to the roller bin 22, which can drive the roller bin 22 and the roller 21 to change their positions, thereby adjusting the inlet size.

[0069] It should be noted that the drum 21 can be directly disposed on the drum bin 22 , or can be detachably connected to the drum bin 22 via the drum seat 23 .

[0070] In some embodiments of the present application, the cleaning assembly 2 includes a roller seat 23, and the roller 21 is rotatably arranged in the roller seat 23. The roller seat 23 has a slide rail 231, and the inner wall of the main body of the roller bin 22 is provided with a slide groove 222 for cooperating with the slide rail 231. By inserting the slide rail 231 of the roller seat 23 into the slide groove 222 of the roller bin 22, the roller 21 can be assembled in the roller bin 22.

[0071] Specifically, the roller seat 23 also includes an end cover 232 and a limit plate 233 connected to both ends of the slide rail 231, which can realize axial limit of the roller 21, so that the roller 21 is not easy to fall out. One end of the roller 21 is rotatably arranged on the end cover 232 through a bearing, and the transmission part 213 at the other end of the roller 21 is arranged opposite to the limit plate 233. The limit plate 233 has a hollow structure, which is convenient for avoiding the connection between the transmission part 213 and the roller driving assembly 24.

[0072] The drum drive assembly 24 includes a drive motor 241, a transmission assembly 242 and a spline shaft 243. The drive motor 241 and the spline shaft 243 are powered by the transmission assembly 242. The spline shaft 243 can be inserted into the transmission part 213 of the drum 21 through the limit plate 233 to drive the drum 21 to rotate. In order to install the drum drive assembly 24, a connecting frame 223 is provided at one end of the drum bin 22, and the drum drive assembly 24 is fixedly arranged on the connecting frame 223.

[0073] In some embodiments of this application, please refer to Figure 1 , Figure 4 and Figure 5 The inlet regulating module also includes a flexible sealing component 4, which is connected between the collecting component 1 and the cleaning component 2 to form a collecting cavity connected to the inlet, thereby preventing solid waste from leaking out of the gap between the collecting component 1 and the cleaning component 2.

[0074] Specifically, the flexible sealing assembly 4 includes a top seal 41 and a side seal 42, wherein the top seal 41 is connected between the top edge of the garbage box 12 and the top edge of the drum bin 22, and can seal the top gap between the garbage box 12 and the drum bin 22 to prevent solid waste from leaking from the top of the garbage box 12. The side seals 42 are arranged on both sides of the garbage box 12, and are respectively connected to the end cover 232 and the limit plate 233, and can be used to seal the gap between the garbage box 12 and the drum bin 22 to prevent solid waste from leaking from both sides of the garbage box 12. During the swinging process of the swing arm 31, the top seal 41 and the side seal 42 will expand and contract with the swinging of the swing arm 31 to adapt to the change in the gap between the garbage box 12 and the drum bin 22. After the solid waste enters from the bottom entrance, it cannot leak through the top or both sides of the garbage box 12, which is conducive to improving the cleaning effect.

[0075] As a specific embodiment of the present application, the top seal 41 and the side seal 42 are flexible rubbers with a corrugated structure and have good elastic deformation capabilities.

[0076] The second aspect of the embodiment of the present application provides a cleaning device, including the inlet adjustment module described in the above embodiment, and the mounting frame 13 in the cleaning component 2 can be used to achieve a fixed connection with the cleaning device body. The cleaning device also includes a negative pressure component 5 and a filter component 6. The negative pressure component 5 is connected to the collection component 1 and can be used to provide negative pressure for the collection component 1, which is conducive to the adsorption and collection of small-sized garbage such as dust and paper scraps, and can avoid dust during the cleaning process, which is conducive to ensuring the air quality of indoor cleaning places. The filter component 6 is arranged between the negative pressure component 5 and the collection component 1, and can block fine particles such as dust, so that they remain in the collection component 1, and only allow the air in the garbage box 12 to pass through the filter component 6, so as to prevent solid garbage from entering the negative pressure component 5 and blocking the negative pressure component 5.

[0077] In some embodiments of the present application, the negative pressure assembly 5 includes a negative pressure chamber 51 connected to the rear of the garbage box 12, and an air duct 52 connected to the fan is provided on the negative pressure chamber 51, which can generate negative pressure inside the negative pressure chamber 51 and the garbage box 12, so as to generate suction for solid waste such as dust. The filter assembly 6 includes a filter element such as HEPA, which is used to filter solid waste such as dust to prevent solid waste from entering the negative pressure chamber 51 or the air duct 52 and affecting the normal operation of the negative pressure assembly 5.

[0078] It should be noted that since a flexible sealing component 4 is provided between the garbage box 12 and the cleaning component 2, a relatively closed collection cavity can be formed between the garbage box 12 and the cleaning component 2, which is beneficial to improving or ensuring the negative pressure adsorption effect of the negative pressure component 5 on dust and small-sized garbage, and is beneficial to improving the dust suction performance of the cleaning device.

[0079] See also Figures 1 to 9 , the working method of the above cleaning device is as follows:

[0080] Step 1: Start the cleaning device to make the drum drive assembly 24, the swing arm drive assembly 32 and the negative pressure assembly 5 work normally;

[0081] Step 2: When the cam 322 rotates to a state where it is separated from the swing arm 31 (such as Figure 4As shown), at this time, the entrance size is the smallest, and the flexible sheet structure 211 on the drum 21 rotates backward to clean the solid garbage. The flexible sheet structure 211 fits the ground and lifts small-sized solid garbage and dust particles backward and upward. The guide member 11 at the front end of the garbage box 12 fits the ground, and its inclined surface supports the lifted solid garbage, so that the garbage enters the garbage box 12 smoothly. The lifted fine dust and lighter garbage are introduced into the garbage box 12, and then move closer to the filter assembly 6 under the action of the negative pressure assembly 5; while the larger garbage is stuck between the drum 21 and the guide member 11, and moves forward with the cleaning device;

[0082] Step 3: As the cleaning device moves forward, the cam 322 continues to move along Figure 4 The cam 322 rotates counterclockwise until the contact surface 3221 contacts the swing arm 31, and the size of the entrance gradually increases. The large-sized garbage originally stuck between the roller 21 and the guide member 11 enters the garbage box 12 under the push of the roller 21. However, due to the enlarged entrance size, the small garbage at the entrance cannot be pushed into the garbage box 12 by the negative pressure or the roller 21, and the small garbage at the entrance is blocked by the guide member 11, so that the small garbage is pushed by the guide member 11 until the cam 322 rotates to a state separated from the swing arm 31, and the size of the entrance gradually decreases, and the small garbage can smoothly enter the garbage box 12 through the action of the negative pressure component 5 and the roller 21.

[0083] It should be noted that the present application realizes the periodic change of the entrance size by rotating the cam 322 to push the swing arm 31 to swing back and forth. Medium-sized solid garbage can be pushed into the garbage box 12 by the roller 21 during the change of the entrance size. The cleaning device of the present application can be used for comprehensive cleaning and collection of small-sized garbage, medium-sized garbage and large-sized garbage by automatically adjusting the entrance size periodically, thereby improving the cleaning efficiency of the cleaning device. The cleaning method is simple and effective, and the structure of the cleaning device is simple, which is conducive to large-scale low-cost manufacturing.
