Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a side sweeping assembly and a cleaning device. Background Art

[0002] As a new type of cleaning appliance, sweeping robots are very convenient to use and are popular among users because of their practical functions such as self-cleaning, automatic garbage dumping, and automatic recharging.

[0003] The sweeping robot is mainly composed of a shell and a side brush installed at the bottom of the shell. When performing cleaning operations, the sweeping robot moves according to a preset cleaning path. The side brush is driven to rotate by a driving part to sweep the debris on the ground to the vicinity of the dust suction port, and the sweeping robot then sucks the debris in.

[0004] However, the side brushes of existing sweeping robots are relatively soft and are only suitable for cleaning hard floors. The cleaning effect is not ideal for cleaning environments with fluff, such as carpets. This is because the fluff on the carpet is long, and dust, hair, and larger particles will penetrate into the bottom layer of the carpet, which causes the softer side brush to be blocked by the fluff of the carpet and unable to penetrate into the bottom layer of the carpet, thereby bringing up the dust and the like that have penetrated into the carpet from the bottom layer, ultimately resulting in the sweeping robot having an extremely unsatisfactory cleaning effect for cleaning environments with fluff, such as carpets.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] As mentioned in the background technology, the existing sweeping robot mainly includes a shell and a side brush mounted on the bottom of the shell. When the sweeping robot is performing cleaning operations, the side brush on the sweeping robot is blocked by the fluff, making it difficult to clean the dust, hair and larger particles that penetrate deep into the bottom of the blanket, which easily leads to poor cleaning effect of the sweeping robot for the cleaning environment with fluff such as the blanket. To this end, the present application provides a new side sweeping assembly, which can solve the problem that the sweeping robot in the prior art is difficult to clean dust, hair and other garbage in the blanket. The side sweeping assembly of the present application will be described in detail below in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 4 As shown, the present application provides a side-sweeping assembly, which includes a main body 10 , a connecting arm 20 and a cleaning arm 30 .

[0036] Among them, the connecting arm 20 includes at least one, and the first end of the connecting arm 20 is connected to the main body 10, and the second end of the connecting arm 20 extends in a direction away from the main body 10; the cleaning arm 30 includes at least one, the cleaning arm 30 is arranged one-to-one with the connecting arm 20, the first end of the cleaning arm 30 is connected to the second end of the connecting arm 20, and each cleaning arm 30 includes a scraping portion 31.

[0037] Optionally, in this embodiment, the connecting arm 20 and the cleaning arm 30 can be provided as one, two, three, four or more than four. Figure 1 To Attachment Figure 3 The figure shows a case where there are three connecting arms 20 and three cleaning arms 30 .

[0038] In this embodiment, when the side sweeping assembly is actually used, the side sweeping assembly can be first installed on a cleaning device (such as a sweeping robot or a cleaning base station, etc.), and then the rotating shaft of the motor in the cleaning device is connected to the main body 10 to drive the main body 10 to rotate, thereby driving the connecting arm 20 and the cleaning arm 30 to rotate synchronously. When the cleaning arm 30 rotates, it can clean environments with fluff such as carpets. At the same time, since the cleaning arm 30 in this embodiment includes a scraping tooth portion 31, and the scraping tooth portion 31 is relatively hard, when the cleaning device is in an environment with fluff such as a blanket, the scraping tooth portion 31 will not be blocked by the fluff of the blanket, so that it can penetrate into the bottom layer of the blanket, and then the hair, dust and large particles on the bottom layer of the blanket can be scraped to the surface of the blanket fluff, and then the hair, dust and large particles on the surface of the blanket can be cleaned and collected by using the side brush of the cleaning device (not shown in the accompanying drawings), effectively ensuring that the cleaning device also has a good cleaning effect on the blanket; at the same time, since a connecting arm 20 is provided between the cleaning arm 30 and the main body 10 in this embodiment, when hair is entangled on the cleaning arm 30, the setting of the connecting arm 20 can extend the distance between the cleaning arm 30 and the main body 10, thereby preventing the hair on the cleaning arm 30 from contacting the main body 10 and being entangled on the main body 10 and the rotating shaft of the motor.

[0039] That is to say, by providing the scraping teeth 31 on the connecting arm 20, the scraping teeth 31 can penetrate into the bottom layer of the blanket, thereby scraping the hair, dust and large particles on the bottom layer of the blanket to the surface of the blanket, and then with the cooperation of the side brush of the cleaning device, the hair, dust and large particles can be cleaned and collected, thereby improving the cleaning effect of the cleaning device. Compared with the structure of the side sweeping assembly in the prior art, the side sweeping assembly in this embodiment can clean the dust, hair and other garbage in the blanket, thereby improving the cleaning efficiency and effectively ensuring the cleaning effect of the cleaning device.

[0040] Combination Figure 1 to Figure 2 As shown, the main body 10 in this embodiment is generally arranged in a columnar block structure, and the columnar block can be a cylindrical block, a prismatic block or other special-shaped column blocks, etc. Figure 2 1 shows the case where the main body 10 is arranged as a cylindrical block structure. In actual connection, the connecting arm 20 is connected to the outer edge of the cylindrical block.

[0041] Further, see Figure 1 as well as Figure 4As shown, the scraping tooth section 31 in this embodiment includes a connecting section 311 and a cleaning tooth section 312. The connecting section 311 is connected to the second end of the connecting arm 20, and the connecting section 311 extends along the length direction of the connecting arm 20; the cleaning tooth section 312 includes at least one, and at least one cleaning tooth section 312 is arranged on the connecting section 311. Specifically, the setting of the connecting section 311 facilitates the connection between the scraping tooth section 31 and the connecting arm 20, and the setting of the cleaning tooth section 312 allows the scraping tooth section 31 to penetrate into the bottom layer of the blanket, thereby more effectively scraping off hair, dust and other garbage in the blanket. It can be understood that the cleaning tooth section 312 in this embodiment may include one, two, three, four or more than four, and any other deformation methods under the conception of the present application are within the protection scope of the present application.

[0042] Further, as shown in the figure, the cleaning tooth segments 312 in this embodiment include multiple cleaning tooth segments 312, which are arranged in sequence along the length direction of the connecting section 311. Such a configuration increases the contact area between the scraping tooth section 31 and the blanket, effectively preventing hair, dust and other garbage from being left in certain areas of the blanket due to insufficient density of the cleaning tooth segments 312, and improving the cleaning effect of the scraping tooth section 31 on the blanket to a certain extent, ensuring that dust and other large particles can be effectively cleaned while removing hair. It is understandable that the cleaning tooth segments 312 in this embodiment may include two, three, four or more than four, which is not specifically limited in this application and can be designed according to processing requirements.

[0043] Optionally, in this embodiment, the predetermined spacing between two adjacent cleaning tooth segments 312 may be 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, 1 cm or more than 1 cm. This application does not make any specific limitations and can be designed according to actual processing requirements, as long as it can ensure that the cleaning tooth segment 312 can penetrate into the bottom layer of the blanket and scrape off hair, dust and other garbage in the blanket.

[0044] Further, see Figure 3 to Figure 4As shown, the first end of the cleaning tooth segment 312 in this embodiment is connected to the connecting segment 311, and the second end of the cleaning tooth segment 312 extends along the length direction perpendicular to the connecting segment 311, and the cross-sectional area of ​​each cleaning tooth segment 312 (i.e., the cross-sectional area obtained by cutting the cleaning tooth segment 312 along the length direction perpendicular to the cleaning tooth segment 312) gradually decreases to zero. Specifically, the second end of the cleaning tooth segment 312 in this embodiment extends along the length direction perpendicular to the connecting segment 311, so that the scraping tooth portion 31 can penetrate into the bottom of the blanket, thereby more effectively scraping off the hair, dust and other garbage embedded in the bottom of the blanket; and the cross-sectional area of ​​each cleaning tooth segment 312 in this embodiment gradually decreases to zero. Such a setting can not only ensure that there is a certain distance between two adjacent cleaning tooth segments 312, so as to scrape off the hair, dust and other garbage in the blanket, but also reduce the weight of the scraping tooth portion 31, thereby reducing the overall weight of the side sweeping assembly, improving the durability of the side sweeping assembly to a certain extent, and extending the service life of the side sweeping assembly.

[0045] Furthermore, a vibration part (not shown in the drawings) is provided on the connecting arm 20 in this embodiment, and the vibration part is used to shake up dust at least. Specifically, the provision of the vibration part can reduce the adhesion between dust, large particles and other garbage and the blanket. When the side sweeping assembly is placed on a blanket or other environment with fluff, the dust, large particles and other garbage accumulated on the blanket can be shaken up by the vibration of the vibration part, so that the side sweeping assembly can more easily clean up dust, large particles and other garbage.

[0046] Optionally, the vibration part in this embodiment can be set inside the connecting arm 20, or it can be set on the side of the connecting arm 20 close to the blanket to be cleaned. This application does not make any specific limitation. As long as it is other deformation methods based on the concept of this application, they are within the protection scope of this application.

[0047] Furthermore, the vibration part includes a vibration motor. Specifically, the vibration motor has a vibration effect, so that the adhesion between dust, large particles and other garbage and the blanket can be reduced, so that dust, large particles and other garbage are more easily removed by the scraping tooth part 31, effectively improving the cleaning efficiency of the side sweeping assembly in this embodiment.

[0048] Furthermore, the second end of the cleaning tooth segment 312 in this embodiment is provided with a rounded corner (not shown in the drawings), and along the width direction of the cleaning tooth segment 312, the rounded corners are provided at opposite ends of the cleaning tooth segment 312. In this way, when the side sweeping assembly rotates, the corners of the second end of the cleaning tooth segment 312 can be prevented from damaging objects in the space, and the scraping tooth portion 31 can also be prevented from scratching the human body during the assembly process.

[0049] Further, see Figure 3 As shown, in this embodiment, the connecting arm 20 and the main body 10 are located on the first plane (with Figure 3 The first angle A is greater than or equal to 30° and less than or equal to 60°. In other words, the first angle A in this embodiment satisfies the relationship: 30°≤A≤60°, such as 30°, 35°, 40°, 45°, 50°, 55°, 60° and any value therebetween. Since the first end of the cleaning arm 30 is connected to the second end of the connecting arm 20, when the first angle A is less than 30°, the contact area between the cleaning arm 30 and the fuzzy environment such as the blanket is reduced during the rotation of the side sweeping assembly, making it difficult to ensure that the cleaning arm 30 always maintains contact with the blanket, thereby reducing the cleaning efficiency of the cleaning arm 30; when the first angle is greater than 60°, although the contact area between the cleaning arm 30 and the blanket is increased, due to the excessively large angle, the second end of the cleaning arm 30 is easily tilted in the direction away from the blanket, thereby reducing the cleaning efficiency of the cleaning arm 30 and increasing the friction between the second end of the cleaning arm 30 and the blanket, causing wear on the cleaning arm 30 and reducing the service life of the side sweeping assembly. That is to say, by making the first angle A satisfy the relationship: 30°≤A≤60°, this embodiment can ensure that the cleaning arm 30 always maintains contact with the blanket, effectively improving the cleaning efficiency of the cleaning arm 30 for hair, dust and other garbage on the bottom of the blanket. At the same time, it can also prevent the cleaning arm 30 from being worn due to excessive friction, effectively ensuring the cleaning effect of the side sweeping assembly.

[0050] Furthermore, in order to facilitate connection with the rotating shaft of the motor, a connecting portion 11 for connecting with a predetermined rotating shaft (ie, the rotating shaft of the motor) is provided on the main body 10 in this embodiment. Exemplarily, the connecting portion 11 may be a connecting hole or a connecting groove.

[0051] Furthermore, the cleaning arm 30 in the present embodiment includes a thermoplastic polyurethane rubber arm. That is to say, the scraping tooth portion 31 in the present embodiment is made of thermoplastic polyurethane rubber (TPU). In this way, since thermoplastic polyurethane rubber (TPU) has the advantages of high strength and good wear resistance, when the thermoplastic polyurethane rubber arm is used as the cleaning arm 30, the structural strength and wear resistance of the scraping tooth portion 31 can be improved, and the scraping tooth portion 31 is convenient for scraping dust, hair and other garbage from the bottom of the blanket to the surface of the blanket, which prolongs the service life of the side sweeping assembly to a certain extent. Of course, in other embodiments of the present application, the cleaning arm 30 may also include an antistatic arm, so that the cleaning arm 30 can have an antistatic effect, thereby preventing the cleaning arm 30 from generating static electricity due to friction with the hair during the process of cleaning the hair, and adsorbing the hair on the cleaning arm 30.

[0052] Furthermore, in order to improve the structural strength and service life of the side sweep assembly in this embodiment, the connecting arm 20 and the main body 10 in this embodiment are processed by integral injection molding, and the structure is stable and reliable. Of course, in other embodiments of the present application, the connecting arm 20 and the main body 10 can also be connected by screw connection, welding or clamping, etc. As long as other deformation methods are based on the concept of this application, they are all within the protection scope of this application.

[0053] Furthermore, in order to improve the structural strength and service life of the side sweeping assembly in this embodiment, the cleaning arm 30 in this embodiment is bonded to the connecting arm 20, which has a simple structure and is easy to process. Of course, in other embodiments of the present application, the cleaning arm 30 and the connecting arm 20 can also be connected by clamping, welding, screwing or integral injection molding. As long as it is other deformation methods under the conception of this application, they are all within the protection scope of this application.

[0054] In combination with the above embodiments, it can be known that the side sweeping assembly of the present application includes a main body, a connecting arm and a cleaning arm. Since the cleaning arm includes a scraping tooth portion, and the scraping tooth portion is relatively hard, when the side sweeping assembly is in an environment with fluff such as a blanket, the scraping tooth portion will not be blocked by the fluff of the blanket, so that it can penetrate into the bottom layer of the blanket, and then the hair, dust and large particles on the bottom layer of the blanket can be scraped to the surface of the blanket fluff, and then the side brush of the cleaning device can be used to clean and collect the hair, dust and large particles on the surface of the blanket, effectively ensuring that the cleaning device also has a good cleaning effect on the blanket.

[0055] On the other hand, the embodiment of the present application further provides a cleaning device, which can be, for example, a sweeping robot, or a cleaning base station, etc. The cleaning device includes the above-mentioned side sweeping component, and therefore, the cleaning device includes all the technical effects of the above-mentioned side sweeping component. Since the technical effects of the side sweeping component have been described in detail above, they will not be repeated here.

[0056] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0057] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0058] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
