Description

Technical Field

[0001] The present invention relates to the field of cleaning technology, and in particular to an automatic cleaning device and method for a vacuum cleaner. Background Art

[0002] A handheld vacuum cleaner is a portable cleaning tool primarily used to clean dust, garbage, hair, and the like. The principle is that an electric motor drives the blades to rotate at high speed, creating negative air pressure within a sealed housing to absorb dust. Existing handheld vacuum cleaners can usually be used with different connectors, such as connecting the floor brush structure to the suction port of the handheld unit via an extension tube.

[0003] Handheld vacuum cleaners are trending towards miniaturization, and as a result, they have the inconvenience of requiring users to frequently empty the dust bucket due to the small dust cup capacity. To address this issue, a vacuum cleaner base station has been developed. It not only provides a fixed storage location for the vacuum cleaner, allowing it to be neatly placed when not in use, avoiding damage or space occupation caused by random placement, but also sucks the dirt and dust collected by the vacuum cleaner into the base station for automatic cleaning of the vacuum cleaner.

[0004] The existing floor brush structure is easily entangled with hair and other flocs during operation, affecting the cleaning effect. It is troublesome for users to clean it manually and easily causes secondary pollution. However, the existing vacuum cleaner base stations on the market do not have the function of cleaning the floor brush structure. Most of them are placed in the air or only serve as a support. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an automatic cleaning device for a vacuum cleaner. When the handheld body of the vacuum cleaner is placed on the support, the floor brush structure just falls into the groove of the tray, and the scraper assembly in the groove can clean the roller brush of the floor brush structure, which not only avoids secondary pollution caused by manual cleaning, but also realizes the automatic cleaning function of the floor brush structure.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is: An automatic cleaning device for a vacuum cleaner includes a base station, wherein the top of the base station is connected to a support for supporting a handheld device body, and the bottom of the base station is installed with a base, and the base is provided with a tray for receiving a floor brush structure, and the tray is provided with a groove, and a scraper assembly for cleaning a roller brush is provided in the groove; and when the handheld device body is placed on the support, the floor brush structure is embedded in the groove.

[0007] Optionally, the scraper assembly includes a plate body, the bottom of the plate body is fixedly connected to the tray, and scraping teeth for cleaning the roller brush are fixedly installed on the inner side of the top of the plate body.

[0008] Optionally, a plurality of scraper assemblies are provided, and the plurality of scraper assemblies are distributed obliquely at intervals on the bottom surface of the groove.

[0009] Optionally, two adjacent scraper assemblies have overlapping portions between their head and tail ends.

[0010] Optionally, the plurality of scraper assemblies are divided into two groups and symmetrically distributed on the bottom surface of the groove.

[0011] Optionally, the scraper assembly includes a V-shaped plate body, and a group of strip plates are respectively provided on both sides of the V-shaped plate body, and the strip plates are equidistantly and obliquely distributed in the groove; The inner sides of the tops of the V-shaped plate and the strip plate are both provided with scraping teeth, and the two groups of strip plates are symmetrically distributed on both sides of the V-shaped plate.

[0012] Optionally, a notch is provided on one side of the base for accommodating the floor brush structure, and the tray is fixedly mounted on the bottom surface of the notch.

[0013] Optionally, a self-cleaning mechanism for cleaning the handset body is provided inside the base station, and the support is connected to the self-cleaning mechanism.

[0014] An automatic cleaning method for a vacuum cleaner comprises the following steps: S1. Install the handheld unit of the vacuum cleaner on the support so that the floor brush structure is located in the groove of the tray; S2. The base station sends a signal to start the handset body, causing the roller brush of the floor brush structure to rotate and interfere with the scraper assembly to clean the roller brush; S3: As the roller brush rotates, the vacuum motor inside the handset works to suck the dirt cleaned by the roller brush into the handset for storage; S4. After the roller brush is cleaned, the dirt stored in the handset body is sucked into the base station along the support by the self-cleaning mechanism.

[0015] Optionally, in step S2, the rotating roller brush interferes with the raised plate body of the scraper assembly, generating vibration to shake off the dust adsorbed on the roller brush, and at the same time, the scraping teeth on the plate body cut off the hair entangled on the roller brush.

[0016] Beneficial effects

[0017] (1) In the present invention, when the handheld body of the vacuum cleaner is placed on the support, the floor brush structure just falls into the groove of the tray, and the roller brush of the floor brush structure interferes with the scraper assembly in the groove. When the roller brush rotates, the scraper assembly can clean the dust and entangled hair adsorbed on it. The principle of the device is simple and the structure is ingenious. It can not only avoid secondary pollution caused by manual cleaning, but also realize the automatic cleaning function of the floor brush structure.

[0018] (2) For the above-mentioned scraper assembly, the cleaning process relies on the rotation of the roller brush itself and the contact between the plate body and scraping teeth on the tray that are inclined at a certain angle to achieve the cleaning effect. It has a simple structure, low cost, and does not require additional moving parts.

[0019] (3) In the present invention, after the floor brush structure is cleaned by the scraper assembly, the dust shaken off the roller brush and dirt such as cut hair can be sucked into the handheld body of the vacuum cleaner, and then the handheld body is cleaned by the base station. This process can be carried out automatically without human intervention, which greatly improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 2 As shown, the vacuum cleaner includes a handheld machine body 7, an extension tube 8 and a floor brush structure 9. The floor brush structure 9 is connected to the suction port of the handheld machine body 7 through the extension tube 8. A rotatable roller brush 901 is installed at the bottom of the floor brush structure 9. The handheld machine body 7 includes a dust cup. A bottom cover that can be opened and closed is provided at the bottom of the dust cup. A vacuum motor for generating negative pressure suction is installed on the top of the dust cup, and one end of the extension tube 8 is connected to the dust cup.

[0024] When the vacuum cleaner is working, the roller brush 901 rotates to disperse the dirt on the ground, the vacuum motor generates negative pressure, and then sucks dust and other dirt into the dust cup along the extension tube 8. When dumping, just open the bottom cover of the dust cup; since the vacuum cleaner is an existing technology, it will not be described in detail.

[0025] The automatic cleaning device includes a base station 1, the top of the base station 1 is connected to a support 6 for supporting the handheld device body 7, and the bottom is installed with a base 2. The base 2 is provided with a tray 3 for receiving the floor brush structure 9, and a groove 4 is provided on the tray 3. The groove 4 is provided with a scraper assembly 5 for cleaning the roller brush 901; and when the handheld device body 7 is placed on the support 6, the floor brush structure 9 is embedded in the groove 4.

[0026] When the roller brush 901 rotates, the dust and entangled hair adsorbed on it can be cleaned through the scraper assembly 5. That is, the device can not only provide a fixed storage location for the vacuum cleaner, automatically clean the dirt stored in the handheld device body 7, but also clean the floor brush structure 9 connected to the handheld device body 7, thereby reducing the user's labor intensity and improving the user's experience.

[0027] As mentioned above, the base station 1 is internally provided with a self-cleaning mechanism for cleaning the handset body 7, and the support 6 is connected to the self-cleaning mechanism. The self-cleaning mechanism can adopt existing technology, that is, the base station 1 itself has the function of cleaning the handset body 7. For example, when a vacuum cleaner is placed on the support 6, the bottom cover of the dust cup automatically opens, and the base station 1 has an internal drive unit that generates negative pressure suction to draw the dust in the dust cup into the corresponding dust bag inside the base station 1. The technology for implementing this function is relatively mature, so it will not be detailed in detail here.

[0028] Furthermore, a notch is provided on one side of the base 2 for accommodating the floor brush structure 9, and the tray 3 is fixedly installed on the bottom surface of the notch; since when the vacuum cleaner is placed vertically, the handheld unit body 7 and the floor brush structure 9 overlap in projection on the ground, in order to enable the vacuum cleaner to be better placed on the base 2, the notch is opened to achieve the avoidance function.

[0029] like Figure 2-Figure 7 As shown, the scraper assembly 5 includes a plate body 51, the bottom of the plate body 51 is fixedly connected to the tray 3, and a scraping tooth 52 for cleaning the roller brush 901 is fixedly installed on the inner side of the top of the plate body 51; the plate body 51 protrudes from the bottom surface of the groove 4, and interferes with the roller brush 901, which can cause the surface of the roller brush 901 to vibrate to shake off dust and other particulate garbage adsorbed thereon, and the scraping tooth 52 is used to cut off the hair wrapped around the roller brush 901. After the hair is cut off, it will also detach from the roller brush 901 and then be sucked into the handheld device body 7.

[0030] As mentioned above, a plurality of scraper assemblies 5 are provided, and the plurality of scraper assemblies 5 are distributed obliquely at intervals on the bottom surface of the groove 4, that is, the scraper assembly 5 has a certain inclination angle relative to the axis of the roller brush 901, and there is a certain interval between two adjacent scraper assemblies 5; during use of the handheld device body 7, hair will be wrapped around the roller brush 901, and the wrapping angle of the hair is consistent with the rotation angle of the roller brush 901. The rotation angle of the roller brush 901 and the inclination angle of the scraper assembly 5 generate tension, and the hair wrapped around the roller brush 901 slides along the inclination angle of the plate body 51, and is thereby cut off by the tiny saw cuts on the scraping teeth 52.

[0031] Furthermore, two adjacent scraper assemblies 5 have overlapping parts between the head and tail ends; there is a specific interval between two adjacent plate bodies 51, so that the head and tail of each raised plate body 51 have a certain overlapping range, which can cover the surface of the entire roller brush 901 to ensure that the entire roller brush 901 can be cleaned, and will not affect the passage of dust or garbage through the interval between the two adjacent plate bodies 51.

[0032] In order to improve the efficiency of garbage suction, multiple scraper assemblies 5 are divided into two groups and symmetrically distributed on the bottom surface of the groove 4; since the scraper assemblies 5 are arranged at an angle, the flow direction of the dirt between the two groups of scraper assemblies 5 tends to the middle after symmetry, which is convenient for the floor brush structure 9 to suck it in. Figure 6 The dotted arrow in the figure indicates the direction of dirt flow. Figure 7 The arrow in is the rotation direction of the roller brush 901.

[0033] Based on the above, the present invention also proposes a preferred structure of the scraper assembly 5 .

[0034] The scraper assembly 5 includes a V-shaped plate body, and a group of strip plates are provided on both sides of the V-shaped plate body. The strip plates are evenly spaced and obliquely distributed in the groove 4; scraping teeth 52 are provided on the inner side of the top of the V-shaped plate body and the strip plates, and the two groups of strip plates are symmetrically distributed on both sides of the V-shaped plate body.

[0035] The scraper assembly 5 has a symmetrical structure and is tilted with a gap therebetween, and the flow of dirt tends to be concentrated. Using this structure to clean the roller brush 901 can achieve better results.

[0036] Working principle: A tray 3 is mounted on the base 2 of the base station 1. When the floor brush cleaning function is used, the floor brush structure 9 is placed on the tray 3. The top surface of the tray 3 has a groove 4. The groove 4 is provided with a raised structure with a certain inclination angle and evenly arranged, namely, a scraper assembly 5; the top of the scraper assembly 5 has several tiny saw cuts for cutting off the hair wrapped around the roller brush 901.

[0037] When the handset body 7 is placed in the base station 1, the base station 1 sends a signal to the handset body 7 to start up through program control. At this time, the roller brush 901 of the floor brush structure 9 starts to rotate; the roller brush 901 will interfere with the scraper assembly 5 on the tray 3 during rotation, thereby generating vibration, and shaking off the dust adsorbed on the roller brush 901; during the use of the handset, hair will be wrapped around the roller brush 901, and the wrapping angle of the hair is consistent with the working rotation angle of the roller brush 901. The rotation angle of the roller brush 901 and the inclination angle of the scraper assembly 5 generate tension, and the hair wrapped around the roller brush 901 slides along the inclination angle of the plate body 51, and is thereby cut off by the tiny saw cuts on the scraping teeth 52.

[0038] Example 2

[0039] like Figures 1-8 As shown, based on the first embodiment, the present invention further proposes an automatic cleaning method for a vacuum cleaner, which uses the automatic cleaning device of the vacuum cleaner in the first embodiment and includes the following steps.

[0040] Step S1: Install the handheld body 7 of the vacuum cleaner on the support 6 so that the floor brush structure 9 is located in the groove 4 of the tray 3; a fixed structure is provided on the top of the support 6 so that the handheld body 7 can be stably placed on the support 6, and under the connection of the extension tube 8, the floor brush structure 9 just falls into the groove 4 of the tray 3, and after the handheld body 7 is placed in the support 6, the bottom cover of its dust cup automatically opens.

[0041] Step S2: The base station 1 sends a signal to start the handset body 7, and the roller brush 901 of the floor brush structure 9 rotates and interferes with the scraper assembly 5 to clean the roller brush 901; the rotating roller brush 901 interferes with the raised plate body 51 of the scraper assembly 5, generating vibration to shake off the dust adsorbed on the roller brush 901, and at the same time, the scraping teeth 52 on the plate body 51 cut off the hair wrapped around the roller brush 901.

[0042] Step S3: While the roller brush 901 is rotating, the vacuum motor inside the handset body 7 works to suck the dirt cleaned from the roller brush 901 into the handset body 7 for storage; after the vacuum cleaner is installed on the automatic cleaning device, it receives a signal from the base station 1 and starts working automatically. When the roller brush 901 rotates, it completes self-cleaning through the scraper assembly 5, and the cleaned hair and dust are sucked into the handset body 7 for storage.

[0043] Step S4: After the roller brush 901 is cleaned, the dirt stored in the handset body 7 is sucked into the base station 1 along the support 6 by the self-cleaning mechanism. The completion of the cleaning of the roller brush 901 can be determined by setting a timer function in the program to shut down the handset body 7. After the cleaning is completed, the self-cleaning mechanism in the base station 1 automatically activates to clean the dust cup of the handset body 7.

[0044] To sum up, the automatic cleaning device proposed in the present invention can not only provide a fixed storage location for the vacuum cleaner and automatically clean the dirt stored in the handheld device body 7, but also clean the floor brush structure 9 connected to the handheld device body 7. The dirt cleaned from the floor brush structure 9 is then sucked in and stored by the vacuum cleaner, and then the handheld device body 7 is cleaned through the self-cleaning mechanism inside the base station 1.

[0045] Among them, for the cleaning structure of the floor brush structure 9, the cleaning process relies on the rotation of the roller brush 901 itself to contact the plate body 51 and the scraping teeth 52 inclined at a certain angle on the tray 3 to achieve the cleaning effect. Its structure is simple, the cost is low, and no additional moving parts are required.
