Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a mite-removing vacuum cleaner. Background Technology

[0002] In related technologies, mite removers include a base, a roller brush, a dust collection cup, and a negative pressure fan. The dust collection cup, negative pressure fan, and roller brush are all installed on the base. The negative pressure fan is used to provide suction for the dust collection cup. The roller brush is located at the bottom of the base. When the base moves on the furniture surface, the roller brush can roll relative to the furniture surface and tap the furniture surface to expose the hidden dust mites. Then, the dust mites are sucked into the dust collection cup for recycling.

[0003] However, this mite remover is not very effective at cleaning. Utility Model Content

[0004] Based on this, the present application provides a mite-removing vacuum cleaner, which has a better cleaning effect.

[0005] The mite-removing vacuum cleaner provided in this application includes:

[0006] The housing has a first mounting groove, a second mounting groove, a first air inlet, and a second air inlet. The first mounting groove, the first air inlet, and the second mounting groove are arranged sequentially along the traveling direction of the mite-removing vacuum cleaner. The first mounting groove is located in front of the housing along the traveling direction of the mite-removing vacuum cleaner. The first mounting groove, the first air inlet, the second mounting groove, and the second air inlet are connected sequentially.

[0007] A roller brush assembly, comprising two roller brushes, one roller brush being disposed in a first mounting slot and the other roller brush being disposed in a second mounting slot;

[0008] A sealing element is connected to the housing. The sealing element includes a first sealing part and two second sealing parts. The first sealing part is disposed on the side of the second mounting groove away from the first air inlet. The two second sealing parts are disposed at both ends of the second mounting groove and connected to both ends of the first sealing part. The end of the second sealing part away from the first sealing part extends beyond the first air inlet.

[0009] The mite-removing vacuum cleaner provided in this embodiment uses a first mounting slot and a second mounting slot to mount two roller brushes, respectively. The two roller brushes enhance the cleaning effect of the roller brush assembly. A first air inlet connects the first and second mounting slots, and a second air inlet connects to the dust cup assembly. This allows airflow to sequentially flow along the first mounting slot, the first air inlet, the second mounting slot, and the second air inlet, concentrating the suction power of the mite-removing vacuum cleaner on the second mounting slot to improve its cleaning effect. A second air inlet is provided on the side of the second mounting slot opposite to the first air inlet. A sealing part is provided, and second sealing parts are provided at both ends of the second mounting groove, so that the sealing element surrounds three sides of the second mounting groove. The end of the second sealing part away from the first sealing part extends beyond the first air inlet, so that the sealing element seals the gap between the housing and the cleaning area on the periphery of the second mounting groove, and seals the gap between the housing and the cleaning area at both ends of the first air inlet. As a result, the airflow will not leak from the above gaps when it flows from the first mounting groove through the first air inlet to the second mounting groove, thereby making the suction power of the mite removal vacuum cleaner more concentrated and improving the cleaning effect of the mite removal vacuum cleaner.

[0010] In one possible implementation, the first sealing portion extends along the axial direction of the roller brush;

[0011] And / or, the second sealing part extends along the direction of travel of the mite-removing vacuum cleaner.

[0012] Thus, when the mite-removing vacuum cleaner comes into contact with the cleaning area, the first sealing part is positioned between the second mounting groove and the rear end of the housing, and the second sealing part can be positioned between the second mounting groove and the left and right sides of the housing. The first sealing part can prevent airflow from leaking from the gap between the housing and the cleaning area to the rear end of the mite-removing vacuum cleaner, and the second sealing part can prevent airflow from leaking from the gap between the housing and the cleaning area to the left and right sides of the mite-removing vacuum cleaner. This allows all the airflow to enter the second mounting groove and then flow out from the second air inlet, thereby improving the suction power of the mite-removing vacuum cleaner.

[0013] In one possible implementation, the seal protrudes from the bottom surface of the housing.

[0014] Thus, when the mite-removing vacuum cleaner is placed in the cleaning area, the seal can abut against the cleaning area, thereby sealing the gap between the housing around the second mounting slot and the cleaning area.

[0015] In one possible implementation, the height of the seal protruding from the housing is greater than or equal to 3 mm and less than or equal to 10 mm.

[0016] This design allows the seal to protrude a certain height from the housing, ensuring that even when the seal partially deforms, it can still effectively abut against the cleaning area when the mite-removing vacuum cleaner is placed on the cleaning area, thus effectively sealing the gap between the second mounting groove and the cleaning area. Furthermore, the seal's protrusion from the housing is not excessive, allowing the roller brush to roll and contact the cleaning area, facilitating its tapping and sweeping action.

[0017] In one possible implementation, the seal includes a connecting portion and a flexible sealing portion, the flexible sealing portion being connected to the connecting portion, and the connecting portion being connected to the housing.

[0018] In this way, the connecting part can be connected to the housing, and then the flexible sealing part can be connected to the housing. The flexible sealing part can generate elastic deformation when the mite removal vacuum cleaner moves and always maintains abutment with the cleaning area, thereby enabling the seal to effectively seal the gap between the housing and the cleaning area on the side of the second mounting groove.

[0019] In one possible implementation, the mite-removing vacuum cleaner also includes a dust cup assembly, with a second air inlet located on the side of the second mounting slot opposite to the first mounting slot, and the second air inlet communicating with the dust cup assembly.

[0020] Thus, the first mounting slot, the first air inlet, the second mounting slot, and the second air inlet are arranged sequentially from front to back along the direction of travel of the mite-removing vacuum cleaner. The airflow basically flows along the direction of travel of the mite-removing vacuum cleaner, which makes the airflow relatively smooth and the suction loss small. After the airflow carries the dust mites into the second mounting slot, it flows to the side of the second mounting slot away from the first mounting slot, where the dust mites can be sucked into the dust cup assembly from the second air inlet and then collected in the dust cup assembly.

[0021] In one possible implementation, in the height direction of the mite-removing vacuum device, the rotation axis of the roller brush located in the second mounting slot is lower than the second air inlet.

[0022] Thus, when the dust mites move with the airflow to the second air inlet, their own inertial force is directed diagonally upward and backward, and the suction force is also directed diagonally upward and backward. In this way, the two forces are in the same direction, thus forming a resultant force, which can more efficiently suck the dust mites into the dust cup assembly.

[0023] In one possible implementation, the two rollers rotate in the same direction.

[0024] In this way, both rollers can collect dust mites in one direction.

[0025] In one possible implementation, the distance between the two roller brushes is smaller than the rotation diameter of the roller brushes.

[0026] In this way, the distance between the first mounting slot and the second mounting slot can be reduced, thereby shortening the airflow path and increasing the suction power of the first mounting slot. This allows the dust mites in the first mounting slot to be fully sucked into the second mounting slot and then collected through the second air inlet.

[0027] In one possible implementation, the two roller brushes include a first roller brush and a second roller brush, with the first roller brush disposed in a first mounting slot and the second roller brush disposed in a second mounting slot.

[0028] The rotation diameter of the first roller brush is greater than that of the second roller brush, and the distance between the first and second roller brushes is less than that of the second roller brush.

[0029] In this way, the linear velocity of the first roller brush can be greater than that of the second roller brush, thereby enhancing the beating effect of the first roller brush. Furthermore, the distance between the two roller brushes is smaller than the rotation diameter of the smaller roller brush, which shortens the distance between the first and second mounting grooves, thus shortening the airflow path and increasing the suction force of the first mounting groove.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components.

[0044] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0045] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0046] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0047] In related technologies, mite removers include a base, a roller brush, a dust collection cup, and a negative pressure fan. The dust collection cup, negative pressure fan, and roller brush are all mounted on the base. The negative pressure fan provides suction to the dust collection cup. The roller brush is located at the bottom of the base. When the base moves across a furniture surface, the roller brush rolls relative to the surface and taps it, exposing hidden dust mites. The mites are then sucked into the dust collection cup for recycling. However, the cleaning effect of this type of mite remover is poor.

[0048] In view of this, this application provides a mite-removing vacuum cleaner. The mite-removing vacuum cleaner has two roller brushes spaced apart along its direction of travel, and the airflow flows sequentially along the first mounting groove, the first air inlet, the second mounting groove, and the second air inlet. When cleaning with the mite-removing vacuum cleaner, the front roller brush first contacts the cleaning area and can beat the cleaning area, thereby fully exposing the hidden dust mites. At the same time, the airflow carries the dust mites to the second mounting groove, and the rear roller brush continues to sweep away the dust mites and sucks them away under the action of the airflow. Since the second mounting groove has a first sealing part on the side away from the first air inlet, when the mite-removing vacuum cleaner comes into contact with the cleaning area, the first sealing part can abut against the cleaning area to seal the gap between the housing and the cleaning area, thereby preventing airflow leakage when the airflow flows from the first air inlet to the second mounting groove, which would reduce the suction power of the mite-removing vacuum cleaner and thus improve the cleaning effect of the mite-removing vacuum cleaner.

[0049] The specific implementation of the mite-removing vacuum cleaner provided in this application will be described in detail below with reference to the accompanying drawings.

[0050] Reference Figures 1 to 4As shown, the mite-removing vacuum cleaner provided in this embodiment includes a housing 100, a roller brush assembly 200, and a sealing element 300. The housing 100 has a first mounting groove 110, a second mounting groove 120, a first air inlet 130, and a second air inlet 140. The first mounting groove 110, the first air inlet 130, and the second mounting groove 120 are located along the traveling direction of the mite-removing vacuum cleaner (refer to...). Figure 1 and Figure 2 The first mounting slot 110 is located in front of the housing 100 along the direction of travel of the mite removal vacuuming device. The first mounting slot 110, the first air inlet 130, the second mounting slot 120 and the second air inlet 140 are connected in sequence. The roller brush assembly 200 includes two roller brushes 210, one roller brush 210 is set in the first mounting slot 110 and the other roller brush 210 is set in the second mounting slot 120.

[0051] The seal 300 is connected to the housing 100. The seal 300 includes a first sealing part 310 and two second sealing parts 320. The first sealing part 310 is disposed on the side of the second mounting groove 120 away from the first air inlet 130. The two second sealing parts 320 are disposed at both ends of the second mounting groove 120 and are connected to both ends of the first sealing part 310. The end of the second sealing part 320 away from the first sealing part 310 may extend beyond the first air inlet 130.

[0052] It should be understood that the mite-removing vacuum cleaner of this embodiment may also include a dust cup assembly (not shown in the figure) and a fan assembly 400. The fan assembly 400 is used to provide negative pressure suction for the mite-removing vacuum cleaner, and the dust cup assembly is used to collect dirt such as dust mites.

[0053] The first mounting slot 110, the first air inlet 130, the second mounting slot 120, the second air inlet 140, the dust cup assembly, and the fan assembly 400 can be connected in sequence, so that the airflow flows along the first mounting slot 110, the first air inlet 130, the second mounting slot 120, the second air inlet 140, the dust cup assembly, and the fan assembly 400 in sequence to suck up dust mites.

[0054] In this embodiment, the first mounting slot 110 and the second mounting slot 120 are respectively used to mount two roller brushes 210. Since the first mounting slot 110 and the second mounting slot 120 are arranged front and back along the traveling direction of the mite-removing vacuum cleaner, when the user pushes the mite-removing vacuum cleaner, the roller brush 210 located in the first mounting slot 110 first contacts the cleaning area and beats the area, thereby fully exposing the hidden dust mites. Then, the roller brush 210 located in the second mounting slot 120 contacts the cleaning area and sweeps away the dust mites, which are then sucked away by the airflow. In this way, the two roller brushes 210 work separately, with one roller brush 210 focusing on beating and the other focusing on sweeping and suction. This allows the mite-removing vacuum cleaner to achieve the function of beating in front and sucking in the back. After fully raising the dust mites on the surface to be cleaned, the dust mites are collected by suction, which can effectively improve the cleaning effect of the mite-removing vacuum cleaner on the cleaning area.

[0055] As the airflow flows sequentially along the first mounting groove 110, the first air inlet 130, the second mounting groove 120, and the second air inlet 140, the suction provided by the fan assembly 400 is concentrated on the second mounting groove 120. Dust mites swept by the second roller brush 212 can be sucked away under the action of greater suction, thereby improving the cleaning effect of the dust mite removal vacuum cleaner.

[0056] During the process of airflow from the first air inlet 130 to the second mounting slot 120 in the first mounting slot 110, if the airflow is dispersed to other places, the suction power of the airflow will be reduced. For example, if the airflow continues to flow behind the mite removal vacuum cleaner in the direction of travel of the device instead of flowing to the second air inlet 140, the airflow will be dispersed and the suction power of the mite removal vacuum cleaner will be reduced.

[0057] Therefore, a first sealing part 310 can be provided on the side of the second mounting groove 120 away from the first air inlet 130. The first sealing part 310 can extend along the axial direction of the roller brush 210, or the extension direction of the first sealing part 310 can be set at an angle to the axial direction of the roller brush 210. Second sealing parts 320 can be provided at both ends of the second mounting groove 120. The second sealing parts 320 can extend along the traveling direction of the mite removal vacuuming device, or the extension direction of the second sealing part 320 can be set at an angle to the traveling direction of the mite removal vacuuming device.

[0058] Thus, the seal 300 can surround the three sides of the second mounting groove 120 and the two ends of the first air inlet 130. When the mite-removing vacuum cleaner comes into contact with the cleaning area, the seal 300 can abut against the cleaning area, thereby sealing the gap between the housing 100 around the second mounting groove 120 and the cleaning area, thus preventing airflow from leaking from the gap between the housing 100 around the second mounting groove 120 and the cleaning area and causing airflow dispersion. In addition, the seal 300 can seal the gap between the housing 100 at both ends of the first air inlet 130 and the cleaning area, thereby preventing airflow from leaking from the gap between the housing 100 at both ends of the first air inlet 130 and the cleaning area and causing airflow dispersion. This allows the suction power of the mite-removing vacuum cleaner to be concentrated on the second mounting groove 120, thereby improving the cleaning effect of the mite-removing vacuum cleaner.

[0059] The mite-removing vacuum cleaner provided in this application includes a housing 100, a roller brush assembly 200, and a seal 300. The housing 100 has a first mounting groove 110, a second mounting groove 120, a first air inlet 130, and a second air inlet 140. The roller brush assembly 200 includes a roller brush 210, and the seal 300 includes a first sealing part 310 and a second sealing part 320. By providing a first mounting slot 110 and a second mounting slot 120 for mounting two roller brushes 210 respectively, the cleaning effect of the roller brush assembly 200 is enhanced. A first air inlet 130 connects the first mounting slot 110 and the second mounting slot 120, and a second air inlet 140 connects to the dust cup assembly. This allows airflow to sequentially flow along the first mounting slot 110, the first air inlet 130, the second mounting slot 120, and the second air inlet 140, concentrating the suction power of the mite-removing vacuum cleaner on the second mounting slot 120 to improve its cleaning effect. The second mounting slot 120 is positioned away from the first... A first sealing part 310 is provided on one side of the air inlet 130, and a second sealing part 320 is provided at both ends of the second mounting groove 120, so that the sealing member 300 surrounds three sides of the second mounting groove 120, so that the sealing member 300 seals the gap between the housing 100 around the second mounting groove 120 and the cleaning area. The end of the second sealing part 320 away from the first sealing part 310 can extend beyond the first air inlet 130. The sealing member 300 can seal the gap between the housing 100 at both ends of the first air inlet 130 and the cleaning area, thereby preventing airflow leakage. This allows the suction power of the mite-removing vacuum cleaner to be more concentrated, thereby improving the cleaning effect of the mite-removing vacuum cleaner.

[0060] In one possible implementation, the first sealing portion 310 is along the axial direction of the roller brush 210 (see reference). Figure 1Extending in the Y direction, the first sealing part 310 extends longer than the second mounting groove 120 in the axial direction of the roller brush 210. In the traveling direction of the mite-removing vacuum cleaner, the second sealing part 320 extends longer than the second mounting groove 120.

[0061] In this way, when the mite-removing vacuum cleaner comes into contact with the cleaning area, the first sealing part 310 is positioned between the second mounting groove 120 and the rear end of the housing 100, and the second sealing part 320 can be positioned between the second mounting groove 120 and the left and right sides of the housing 100. The first sealing part 310 can prevent airflow from leaking from the gap between the housing 100 and the cleaning area to the rear end of the mite-removing vacuum cleaner, and the second sealing part 320 can prevent airflow from leaking from the gap between the housing 100 and the cleaning area to the left and right sides of the mite-removing vacuum cleaner. This allows all the airflow to enter the second mounting groove 120 and then flow out from the second air inlet 140, thereby improving the suction power of the mite-removing vacuum cleaner.

[0062] In some embodiments, the seal 300 protrudes from the bottom surface of the housing 100. This arrangement allows the seal 300 to abut against the cleaning area when the mite-removing vacuum cleaner is placed there, thereby sealing the gap between the housing 100 and the cleaning area around the second mounting groove 120.

[0063] In some embodiments, the height of the seal 300 protruding from the housing 100 is greater than or equal to 3 mm and less than or equal to 10 mm. This configuration allows the seal 300 to protrude from the housing 100 by a certain height, ensuring that when the mite-removing vacuum cleaner is placed on the cleaning area and the seal 300 undergoes partial deformation, it can still effectively abut against the cleaning area, thereby effectively sealing the gap between the second mounting groove 120 and the cleaning area. Furthermore, the height of the seal 300 protruding from the housing 100 is not excessive, allowing the roller brush 210 to roll and contact the cleaning area, facilitating the roller brush 210's tapping and sweeping of the cleaning area.

[0064] It should be noted that, in the axial direction of the roller brush 210, if the extension length of the first air inlet 130 is greater than the extension length of the second mounting groove 120, in order to prevent airflow from leaking outward from the first air inlet 130, seals 300 can also be provided at both ends of the first air inlet 130. Therefore, in some embodiments, the end of the second sealing part 320 facing away from the first sealing part 310 can extend beyond the first air inlet. In this way, the second sealing part 320 can seal the gap between the housing 100 at both ends of the first air inlet 130 and the cleaning area, thereby preventing airflow from leaking out of the gap and causing a decrease in suction power, thereby improving the dust collection effect of the mite removal vacuum cleaner.

[0065] It is understandable that the structure of the seal 300 in contact with the cleaning area can be made of a flexible material, so that the seal 300 can undergo elastic deformation when the mite-removing vacuum cleaner moves, thereby ensuring that the seal 300 can always maintain good contact with the cleaning area to improve the sealing effect. Therefore, in one possible implementation, the seal 300 includes a connecting part and a flexible sealing part, the flexible sealing part being connected to the connecting part, and the connecting part being connected to the housing 100.

[0066] With this configuration, the connecting part can be connected to the housing 100, thereby connecting the flexible sealing part to the housing 100. The flexible sealing part can undergo elastic deformation when the mite removal vacuum cleaner moves, and always maintains abutment with the cleaning area, thereby enabling the sealing element 300 to effectively seal the gap between the housing 100 and the cleaning area on the side of the second mounting groove 120.

[0067] For example, the flexible seal may be made of soft rubber or wool.

[0068] In some embodiments, the mite-removing vacuum cleaner also includes a dust cup assembly, with a second air inlet 140 located on the side of the second mounting groove 120 opposite to the first mounting groove 110, and the second air inlet 140 communicating with the dust cup assembly.

[0069] In this way, the first mounting slot 110, the first air inlet 130, the second mounting slot 120, and the second air inlet 140 are arranged sequentially from front to back along the direction of travel of the mite removal vacuum cleaner. The airflow basically flows along the direction of travel of the mite removal vacuum cleaner, which makes the airflow relatively smooth and the suction loss small. After the airflow carries the dust mites into the second mounting slot 120, it flows to the side of the second mounting slot 120 away from the first mounting slot 110, and can suck the dust mites into the dust cup assembly from the second air inlet 140, and then collect the dust mites in the dust cup assembly.

[0070] In some embodiments, in the height direction of the mite-removing vacuum cleaner (refer to...) Figure 2 In the Z direction, the rotation axis of the roller brush 210 located in the second mounting groove 120 is lower than that of the second air inlet 140.

[0071] In this way, when the dust mite moves with the airflow to the second air inlet 140, the inertial force of the dust mite itself is directed diagonally upward and backward, and the suction force is also directed diagonally upward and backward. Thus, the two forces are in the same direction, forming a resultant force, which can more efficiently suck the dust mite into the dust cup assembly.

[0072] In one possible implementation, the two roller brushes 210 rotate in the same direction.

[0073] Understandably, since the first mounting slot 110, the first air inlet 130, the second mounting slot 120, the second air inlet 140, and the dust cup assembly are connected in sequence, and the airflow flows along the first mounting slot 110, the first air inlet 130, the second mounting slot 120, the second air inlet 140, and the dust cup assembly in sequence, the dust mites in the cleaning area need to enter the second mounting slot 120 before they can enter the dust cup assembly. When the mite removal vacuum cleaner moves forward, it needs to gather the dust mites in one direction and finally be sucked into the dust cup assembly through the second air inlet 140. Therefore, the rotation direction of the two roller brushes 210 needs to be consistent so that both roller brushes 210 gather the dust mites in one direction.

[0074] Both rollers 210 can rotate counterclockwise.

[0075] In some embodiments, the distance between the two roller brushes 210 is smaller than the rotation diameter of the roller brushes 210. This arrangement reduces the distance between the first mounting groove 110 and the second mounting groove 120, thereby shortening the airflow path and increasing the suction power of the first mounting groove 110. This allows dust mites in the first mounting groove 110 to be fully drawn into the second mounting groove 120 and then uniformly recycled through the second air inlet 140.

[0076] Reference Figures 2 to 4 As shown, in one possible implementation, the two roller brushes 210 include a first roller brush 211 and a second roller brush 212. The first roller brush 211 is disposed in a first mounting groove 110, and the second roller brush 212 is disposed in a second mounting groove 120. The rotation diameter of the first roller brush 211 is larger than the rotation diameter of the second roller brush 212, and the distance between the first roller brush 211 and the second roller brush 212 is smaller than the rotation diameter of the second roller brush 212.

[0077] It should be understood that when the first roller brush 211 and the second roller brush 212 rotate synchronously, since the rotation diameter of the first roller brush 211 is larger than that of the second roller brush 212, the linear velocity of the first roller brush 211 is greater than that of the second roller brush 212, thereby enhancing the beating effect of the first roller brush 211. Furthermore, the distance between the two roller brushes 210 is smaller than the rotation diameter of the smaller roller brush 210, which shortens the distance between the first mounting groove 110 and the second mounting groove 120, thereby shortening the airflow path and increasing the suction force of the first mounting groove 110.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
