Description

Technical Field

[0001] This application relates to the field of environmental cleaning electrical appliances, and in particular to a mite removal device. Background Technology

[0002] The mite remover can achieve deep mite removal and cleaning of home surfaces through the combined use of multiple technologies such as high-frequency tapping and powerful vacuuming.

[0003] In related technologies, a mite remover includes a base, a roller brush, and a roller brush cover. The bottom of the base has a roller brush groove that is open to the surface of the furniture. A suction port is located on the rear side of the roller brush groove. The roller brush is rotated and positioned inside the roller brush groove. The roller brush cover is located in the opening of the roller brush groove and has multiple grids. The grid openings between adjacent grids allow airflow to enter the roller brush groove through the grid openings and then enter the suction port. The grids can prevent fabrics and other objects from being sucked into the mite remover and prevent hair from getting tangled on the roller brush. However, the grids can also prevent hair and other objects from entering the suction port, thereby reducing the cleaning effect of the mite remover. Utility Model Content

[0004] Based on this, this application provides a mite removal device, which has a good cleaning effect.

[0005] This application provides a mite removal device, including:

[0006] The housing has a placement surface configured to contact the surface to be cleaned, and a suction port is provided on the side of the housing near the placement surface.

[0007] A cover plate is connected to one side of the housing with a placement surface. The cover plate includes a cover plate body and at least one partition rib. The cover plate body is provided with an air inlet. The partition rib extends along the direction of travel of the mite removal device. At least one partition rib is connected to the cover plate body to divide the air inlet into at least two sub-air inlets. The sub-air inlets are connected to the suction port.

[0008] The projection of the dividing rib on the placement surface is offset from the projection of the suction port on the placement surface.

[0009] The mite removal device provided in this application embodiment has a placement surface for contacting the surface to be cleaned, a suction port for sucking up dust mites, hair and other dirt from the surface to be cleaned, and a partition rib for dividing the air inlet of the cover body into multiple sub-air inlets. The partition rib prevents the fabric from being sucked up and allows external airflow to enter the suction port from each sub-air inlet. By setting the projection of the partition rib on the placement surface to be staggered from the projection of the suction port on the placement surface, the partition rib avoids the suction port, so that hair is not blocked by the partition rib and cannot be smoothly sucked into the suction port, thereby effectively improving the cleaning effect of the mite removal device.

[0010] In one possible implementation, the sub-inlet includes a first sub-inlet and at least two second sub-inlets, with the at least two second sub-inlets located on either side of the first sub-inlet.

[0011] The projection of the first sub-inlet on the placement surface coincides at least partially with the projection of the suction port on the placement surface.

[0012] In this way, the suction port can be set to correspond with the first sub-air inlet, and the first sub-air inlet is located in the middle of the multiple sub-air inlets, which helps to optimize the airflow path of the mite removal device. In addition, the partition ribs on both sides of the first sub-air inlet avoid the suction port, which can effectively prevent hair from being blocked by the partition ribs on both sides of the first sub-air inlet and thus unable to enter the suction port smoothly.

[0013] In one possible implementation, at least two second sub-inlets are symmetrically located on opposite sides of the first sub-inlet.

[0014] In this way, the first sub-air inlet can be centrally located on the cover plate, and since the suction port is correspondingly located to the first sub-air inlet, the suction port can also be centrally located along the width of the shell. This helps to optimize the airflow path of the mite removal device, and makes it easier for the airflow to converge from the side of the suction port towards the suction port, thereby improving the cleaning effect of the mite removal device.

[0015] In one possible implementation, the area of ​​the first sub-inlet is greater than or equal to the area of ​​the second sub-inlet.

[0016] In this way, a larger number of partition ribs can be set to improve the effect of preventing hair from getting tangled. Furthermore, the partition ribs can completely avoid the suction port, thereby preventing hair from getting caught on the partition ribs on both sides of the first sub-inlet, thus improving the suction effect of the suction port.

[0017] In one possible implementation, the first sub-air inlet includes a first side edge and a second side edge, the first side edge and the second side edge are arranged opposite to each other along the direction of travel of the mite removal device, and the first side edge is located in front of the second side edge;

[0018] The first side edge extends along an arc and bends away from the second side edge.

[0019] Thus, since the first sub-air inlet and the suction port are set to correspond, the suction at the first sub-air inlet is stronger, and the first side edge is located at the front end of the first sub-air inlet and bends toward the front end of the mite removal device. This can increase the area of ​​the first sub-air inlet and help guide the external airflow into the first sub-air inlet, making it easier for dirt to be sucked in from the first sub-air inlet, which in turn helps the dirt to be sucked into the suction port.

[0020] In one possible implementation, the cover plate is also provided with at least two guide channels, which are located in front of the sub-air inlet along the direction of travel of the mite removal device, and the guide channels are set one-to-one with the sub-air inlet.

[0021] In this way, the guide channel has the function of guiding airflow, which allows the external airflow to carry the dirt along the guide channel backward and into the corresponding sub-air inlet, thus facilitating the suction of dirt.

[0022] In one possible implementation, the width of the back ion inlet side of the guide channel is greater than the width of the side of the guide channel closer to the sub-inlet.

[0023] In this way, the external airflow can gradually converge as it flows backward along the guide channel, which is conducive to the airflow entering each sub-inlet.

[0024] In one possible implementation, the cover plate also includes guide ribs connected to the cover plate body;

[0025] Each sub-inlet is provided with two guide ribs, and the two guide ribs corresponding to each sub-inlet, together with the cover plate body, define the guide groove.

[0026] In this way, by setting multiple guide ribs on the cover plate body, and then defining multiple guide channels together with the cover plate body, and setting the guide channels one by one with the sub-air inlets, it is beneficial for the external airflow to carry the dirt along the guide channels to the corresponding sub-air inlets.

[0027] In one possible implementation, the two guide ribs corresponding to each sub-air inlet are inclined relative to the direction of travel of the mite removal device, and the inclination directions are opposite.

[0028] In this way, the width of the guide channel can gradually increase from the side near the sub-inlet to the side of the back ion inlet, which is conducive to guiding the external air to gradually gather when it flows backward.

[0029] In one possible implementation, the mite removal device further includes a cleaning component, the housing has a mounting groove, the cleaning component is rotatably disposed in the mounting groove, and the suction port is connected to the mounting groove;

[0030] The mounting slot has an opening on the side facing the placement surface, and a cover plate is located at the opening.

[0031] In this way, the cleaning component can tap the surface to be cleaned to fully expose the dust mites. The cleaning component can also help to roll up the dirt on the surface to be cleaned. When the cover is in the opening, the cover can effectively prevent hair from getting tangled on the cleaning component, thereby reducing the cleaning burden on the user. In addition, the external airflow can carry the dirt from the sub-air inlet into the mounting slot, and then into the suction port, thereby completing the vacuuming operation on the surface to be cleaned.

[0057] 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.

[0058] 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. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] 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.

[0060] 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 in orders other than those illustrated or described herein.

[0061] 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.

[0062] Mite removers utilize multiple technologies, including high-frequency beating and powerful suction, to achieve deep mite removal and cleaning of home surfaces. In this technology, the mite remover includes a base, a roller brush, and a roller brush cover. The base has an open roller brush groove facing the home surface, with a suction port at the rear. The roller brush rotates within the groove. The roller brush cover is located at the opening of the groove and has multiple grids. Adjacent grids form grid openings, allowing airflow to enter the roller brush groove and then the suction port. The grids prevent fabrics and other objects from being sucked into the mite remover and prevent hair from getting tangled on the roller brush. However, the grids also prevent hair and other objects from entering the suction port, thus reducing the cleaning effectiveness of the mite remover.

[0063] In view of the above problems, this application provides a mite removal device that improves the cleaning effect of the mite removal device by making the partition ribs avoid the suction port, thereby preventing dirt such as hair from being blocked by the partition ribs and unable to be smoothly sucked into the suction port.

[0064] The specific implementation of the mite removal device provided in this application will be described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 9As shown in the embodiment of this application, the mite removal device includes a housing 100 and a cover plate 200. The housing 100 is provided with a placement surface 110, which is configured to contact the surface to be cleaned. A suction port 120 is provided on the side of the housing 100 near the placement surface 110.

[0066] A cover plate 200 is connected to one side of the housing 100 having a placement surface 110. The cover plate 200 includes a cover plate body 210 and at least one partition rib 220. The cover plate body 210 has an air inlet 211. The partition rib 220 extends along the traveling direction of the mite removal device. At least one partition rib 220 is connected to the cover plate body 210 to divide the air inlet 211 into at least two sub-air inlets 2111. The sub-air inlets 2111 communicate with the suction port 120. The orthographic projection of the partition rib 220 on the placement surface 110 is offset from the orthographic projection of the suction port 120 on the placement surface 110.

[0067] It is understandable that the mite removal device may also include a cleaning component 300, a fan assembly, and a dust collection assembly. The housing 100 is used to integrate the cover plate 200, the cleaning component 300, and the fan assembly. Since the bottom of the cover plate 200 has a relatively flat placement surface 110, it is easier for the placement surface 110 to contact the surface to be cleaned. This makes it easier for the user to move the mite removal device back and forth on the surface to be cleaned, and to suck away dust mites, hair, and other dirt from the surface to be cleaned through the suction port 120.

[0068] Because the fabric is relatively soft, the fabric is easily sucked up by the suction of the mite removal device when it moves on the fabric surface. The cover plate 200 at the bottom of the housing 100 effectively avoids this phenomenon. This is because the cover plate 200 has dividing ribs 220. Since the dividing ribs 220 extend along the direction of travel of the mite removal device, and multiple dividing ribs 220 are spaced apart along the width direction of the mite removal device, the air inlet 211 can be divided into multiple sub-air inlets 2111 arranged along the width direction of the mite removal device. The size of each sub-air inlet 2111 can be the same or different. The direction of travel of the mite removal device can be referenced... Figure 3 The X direction and the width direction of the mite removal device can be referenced. Figure 3 in the Y direction.

[0069] In this way, the partition 220 can prevent the fabric from being sucked up, and the external airflow can also enter the suction port 120 from the sub-air inlet 2111. Alternatively, when the bottom of the housing 100 is provided with the cleaning element 300, dirt such as hair and threads can easily get tangled on the cleaning element 300, thereby weakening the cleaning effect of the cleaning element 300. The partition 220 can disperse the airflow, thereby preventing hair and other dirt flowing with the airflow from getting tangled on the cleaning element 300. In addition, small particles of dirt such as dust mites can still enter the suction port 120 from each sub-air inlet 2111 with the airflow.

[0070] Understandably, because the projection of the partition 220 onto the placement surface 110 is offset from the projection of the suction port 120 onto the placement surface 110 (when the mite removal device is placed horizontally, the placement surface 110 can be understood as a horizontal plane, and both the partition 220 and the suction port 120 are projected vertically onto the horizontal plane), the suction port 120 can be positioned corresponding to one sub-air inlet 2111, and the suction port 120 will not cross two sub-air inlets 2111. Consequently, the partition 220 can be positioned to avoid the suction port 120. Thus, when the mite removal device cleans the surface to be cleaned, the partition 220 can prevent soft fabrics from being sucked up and prevent hair from getting tangled on the cleaning component 300. Furthermore, hair will not be blocked by the partition 220 and thus will not be unable to be smoothly sucked into the suction port 120. In this way, the cleaning effect of the mite removal device can be effectively improved.

[0071] The mite removal device provided in this application embodiment includes a housing 100 and a cover plate 200. The housing 100 includes a placement surface 110 and a suction port 120. The cover plate 200 includes a cover plate body 210 and a partition rib 220. The cover plate body 210 includes an air inlet 211, and the air inlet 211 includes a sub-air inlet 2111. By setting the placement surface 110 for contact with the surface to be cleaned, and the suction port 120 for sucking away dust mites, hair, and other dirt from the surface to be cleaned, and by setting the partition ribs 220 for dividing the air inlet 211 of the cover body 210 into multiple sub-air inlets 2111, the partition ribs 220 prevent the fabric from being sucked up, and allow external airflow to enter the suction port 120 from each sub-air inlet 2111. By setting the projection of the partition ribs 220 on the placement surface 110 to be staggered from the projection of the suction port 120 on the placement surface 110, the partition ribs 220 avoid the suction port 120, so that hair will not be blocked by the partition ribs 220 and cannot be smoothly sucked into the suction port 120, thereby effectively improving the cleaning effect of the mite removal device.

[0072] Reference Figures 6 to 9 As shown, in one possible implementation, the sub-inlet 2111 includes a first sub-inlet 21111 and at least two second sub-inlets 21112, with the at least two second sub-inlets 21112 located on either side of the first sub-inlet 21111. The projection of the first sub-inlet 21111 onto the placement surface 110 at least partially overlaps with the projection of the suction port 120 onto the placement surface 110.

[0073] For example, the sub-air inlet 2111 may include a first sub-air inlet 21111 and two second sub-air inlets 21112, with the two second sub-air inlets 21112 located on opposite sides of the first sub-air inlet 21111. Since the projection of the first sub-air inlet 21111 on the placement surface 110 at least partially overlaps with the projection of the suction port 120 on the placement surface 110, or, the sub-air inlet 2111 may include a first sub-air inlet 21111 and four second sub-air inlets 21112, with two second sub-air inlets 21112 located on one side of the first sub-air inlet 21111 and the remaining two second sub-air inlets 21112 located on the other side of the first sub-air inlet 21111.

[0074] In this way, the suction port 120 can be set to correspond with the first sub-air inlet 21111, and the first sub-air inlet 21111 is located in the middle of the multiple sub-air inlets 2111, which is conducive to optimizing the airflow path of the mite removal device. In addition, the partition ribs 220 on both sides of the first sub-air inlet 21111 avoid the suction port 120, which can effectively prevent hair from being blocked by the partition ribs 220 on both sides of the first sub-air inlet 21111 and thus unable to enter the suction port 120 smoothly.

[0075] In some embodiments, at least two second sub-inlets 21112 are symmetrically arranged on opposite sides of the first sub-inlet 21111.

[0076] In other words, the first sub-air inlet 21111 is centrally located on the cover plate 200, and since the suction port 120 is correspondingly located to the first sub-air inlet 21111, the suction port 120 can also be centrally located along the width direction of the housing 100. This helps to optimize the airflow path of the mite removal device, and helps the airflow to converge from the side of the suction port 120 towards the suction port 120, thereby improving the cleaning effect of the mite removal device.

[0077] In one possible implementation, the area of ​​the first sub-inlet 21111 is greater than or equal to the area of ​​the second sub-inlet 21112.

[0078] It should be noted that, in order to ensure the suction effect of the suction port 120, the area of ​​the suction port 120 needs to be large enough to efficiently remove dirt such as dust mites and hair. Since the first sub-inlet 21111 is set to correspond to the suction port 120, if the area of ​​the first sub-inlet 21111 is small, the partition ribs 220 on both sides of the first sub-inlet 21111 cannot completely avoid the suction port 120. Therefore, in specific implementation, the first sub-inlet 21111 corresponding to the suction port 120 can be set to be larger, and the second sub-inlet 21112 can be set to be smaller. This allows for the setting of more partition ribs 220, which can improve the effect of preventing hair from getting tangled. Furthermore, the partition ribs 220 can completely avoid the suction port 120, thereby preventing the partition ribs 220 on both sides of the first sub-inlet 21111 from catching hair, thus improving the suction effect of the suction port 120.

[0079] In some embodiments, the first sub-air inlet 21111 includes a first side edge and a second side edge, which are disposed opposite to each other along the travel direction of the mite removal device, with the first side edge located in front of the second side edge. The first side edge extends along an arc and bends away from the second side edge.

[0080] Since the first side edge and the second side edge are arranged opposite to each other along the direction of travel of the mite removal device, and the first side edge and the second side edge extend roughly along the width direction of the mite removal device, and since the first sub-air inlet 21111 is correspondingly arranged with the suction port 120, the suction at the first sub-air inlet 21111 is stronger, and the first side edge is located at the front end of the first sub-air inlet 21111 and bends toward the front end of the mite removal device, this can expand the area of ​​the first sub-air inlet 21111 and facilitate the guidance of external airflow into the first sub-air inlet 21111, thereby making it easier for dirt to be sucked in from the first sub-air inlet 21111, which is conducive to the dirt being sucked into the suction port 120.

[0081] Reference Figure 5 and Figure 7 As shown, in one possible implementation, the cover plate 200 is also provided with at least two guide channels 230, which are located in front of the sub-air inlet 2111 along the direction of travel of the mite removal device, and the guide channels 230 are arranged in a one-to-one correspondence with the sub-air inlet 2111.

[0082] With this configuration, the guide channel 230 has the function of guiding airflow, so that the external airflow can carry the dirt along the guide channel 230 to flow backward and enter the corresponding sub-air inlet 2111, which is conducive to the dirt being sucked into the suction port 120.

[0083] In some embodiments, the width of the back ion inlet 2111 side of the guide channel 230 is greater than the width of the side of the guide channel 230 near the sub-inlet 2111.

[0084] In other words, the guide channel 230 can be conical, with the large-diameter end of the guide channel 230 being far away from the sub-air inlet 2111 and the small-diameter end of the guide channel 230 being close to the sub-air inlet 2111. This allows the external airflow to gradually converge as it flows backward along the guide channel 230, which in turn facilitates the airflow entering each sub-air inlet 2111.

[0085] Reference Figure 2 , Figure 5 and Figure 7 As shown, in one possible implementation, the cover plate 200 further includes guide ribs 240 connected to the cover plate body 210. Each sub-inlet 2111 is provided with two guide ribs 240, and the two guide ribs 240 corresponding to each sub-inlet 2111 and the cover plate body 210 together define the guide groove 230.

[0086] Thus, by setting multiple guide ribs 240 on the cover plate body 210, multiple guide grooves 230 are defined together by the multiple guide ribs 240 and the cover plate body 210, and the guide grooves 230 are set one-to-one with the sub-air inlets 2111, which is conducive to the external airflow carrying the dirt along the guide grooves 230 to the corresponding sub-air inlets 2111.

[0087] In some embodiments, the two guide ribs 240 corresponding to each sub-air inlet 2111 are inclined relative to the direction of travel of the mite removal device, and the inclination directions are opposite.

[0088] In this way, since the guide channel 230 is composed of the guide rib 240 and the cover plate body 210, and the two guide ribs 240 corresponding to each sub-air inlet 2111 are inclined in opposite directions, the width of the guide channel 230 can gradually increase from the side near the sub-air inlet 2111 to the side of the back ion air inlet 2111, which is conducive to guiding the external air to gradually gather when it flows backward.

[0089] Reference Figure 3 As shown, in some embodiments, the mite removal device further includes a cleaning component 300. The housing 100 has a mounting groove, the cleaning component 300 is rotatably disposed in the mounting groove, and the suction port 120 communicates with the mounting groove. The mounting groove has an opening on the side facing the placement surface 110, and a cover plate 200 is disposed in the opening.

[0090] In this way, the cleaning component 300 can tap the surface to be cleaned to fully expose the dust mites. The cleaning component 300 can also help to roll up the dirt on the surface to be cleaned. When the cover plate 200 is in the opening, the cover plate 200 can effectively prevent hair from getting tangled on the cleaning component 300, thereby reducing the cleaning burden on the user. In addition, the external airflow can carry the dirt from the sub-air inlet 2111 into the mounting slot, and then into the suction port 120, thereby completing the vacuuming operation on the surface to be cleaned.

[0091] The cover plate 200 can be detachably connected to the housing 100 via clips or the like, so that the cleaning component 300 can be cleaned after the cover plate 200 is removed.

[0092] 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.
