[0047] Embodiment one

[0048] The present embodiment is basically as shown in Figure 1 , Figure 2 , Figure 3 and Figure 11 :

[0049] Referring to Figure 1 and Figure 2 , the present embodiment provides a cleaning brush assembly, which comprises a main body 101, a first mounting structure 102 and a second mounting structure 103 arranged at two ends of the main body 101;

[0050] The first mounting structure 102 is provided with a first through hole 21 in a first direction, the second mounting structure 103 is provided with a clamping groove in a second direction, and the second mounting structure 103 is provided with a second through hole 31 matched with the first through hole in the first direction; wherein the first direction and the second direction are perpendicular;

[0051] At least one side of the first mounting structure 102 is provided with a clamping block 22, and the edge of the second mounting structure 103 is circumferentially provided with at least two clamping teeth 32;

[0052] When the first mounting structure of one of the cleaning brush assemblies is inserted into the clamping groove of the other cleaning brush assembly in the second direction, and the clamping block is inserted into different clamping teeth, the two cleaning brush assemblies have different angles, the first through hole and the second through hole are matched, the second mounting structure limits the first mounting structure in the first direction, and the clamping teeth limit the clamping block in the circumferential direction.

[0053] Wherein, referring to Figure 2 , the first direction refers to the Z-axis direction in the figure, the second direction refers to the direction perpendicular to the Z-axis, the second direction is parallel to the plane where the X-axis and the Y-axis are located, and the circumferential direction refers to the direction indicated by the bidirectional arrow in the figure.

[0054] In some embodiments, the edges of the first mounting structure and the second mounting structure are both arc-shaped, and the first through hole and the second through hole are both circular through holes, so that when the clamping block and the clamping teeth located at different positions of the edge of the second mounting structure are matched, the first through hole and the second through hole can be correspondingly connected to facilitate the fixing of the two by the installation connecting assembly, and the edges are both arc-shaped, which can make the installation process smoother and avoid mutual restriction between the first mounting structure and the second mounting structure.

[0055] In some embodiments, both sides of the first mounting structure are provided with clamping blocks, and correspondingly, both sides of the second mounting structure are provided with at least two clamping teeth. In other words, the edge of the second mounting structure is circumferentially provided with two groups of clamping teeth, and the two groups of clamping teeth are located on both sides of the clamping groove, wherein one group of clamping teeth includes at least two clamping teeth, and the two clamping teeth are located at different positions of the edge of the second mounting structure. In some specific embodiments, the two groups of clamping teeth are located on both sides of the second mounting structure, that is, the two groups of clamping teeth are arranged along the Z-axis, and when one of the clamping blocks on the first mounting structure is matched with one of the clamping teeth on one side of the second mounting structure, the other clamping block on the first mounting structure is automatically aligned with the other clamping tooth on the other side of the second mounting structure.

[0056] Exemplarily, referring to Figure 11The three teeth are a first tooth 321, a second tooth 322, and a third tooth 323. When the clamping block of any one of the adjacent two cleaning brush assemblies is inserted into the first tooth 321, the three cleaning brush assemblies can be assembled into a triangular cleaning brush. When the clamping block of any one of the adjacent two cleaning brush assemblies is inserted into the second tooth 322, the four cleaning brush assemblies can be assembled into a quadrilateral cleaning brush. When the clamping block of any one of the adjacent two cleaning brush assemblies is inserted into the third tooth 323, the five cleaning brush assemblies can be assembled into a pentagonal cleaning brush. It should be noted that the present embodiment provides an example of three teeth, i.e., the combination of three, four, and five cleaning brush assemblies. Of course, more teeth can be provided by those skilled in the art, and different numbers of cleaning brush assemblies can be selected to form a cleaning brush according to actual needs.

[0057] In some embodiments, referring to Figure 2 The second mounting structure includes an upper plate 33 and a lower plate 34 located on both sides of the clamping groove. The upper plate 33 and the lower plate 34 are respectively provided with a first sub-through hole and a second sub-through hole. The first sub-through hole, the clamping groove, and the second sub-through hole are in communication to form the second through hole 31. The two groups of teeth 32 are respectively arranged on the upper plate 33 and the lower plate 34. By forming a gap (i.e., a clamping groove) between the upper plate and the lower plate, and respectively arranging clamping structures (teeth) on the upper plate and the lower plate, the first mounting structure can be inserted into the second mounting structure in one key, and the second mounting structure can also realize multi-directional limiting of the first mounting structure. Therefore, the connection between the two is more convenient, and the stability is also greatly improved.

[0058] In some embodiments, the first side of the cleaning brush assembly is provided with a mounting structure, and the mounting structure can be fixedly or detachably mounted with cleaning units of different shapes. In some specific embodiments, the mounting structure can be a clamping strip. Correspondingly, the cleaning unit is provided with a groove structure on the side connected to the cleaning brush assembly. When the clamping strip is inserted into the groove structure, the cleaning brush assembly and the cleaning unit can be relatively fixed.

[0059] In some embodiments, the cleaning unit is one of a cleaning cloth, a spatula, a brush, and a brush tooth unit.

[0060] In some embodiments, the scraper includes a plurality of scrapers with different hardness, and the brush unit includes a brush unit with different sizes of brush teeth. For smooth surfaces such as glass, a softer scraper such as a silica gel scraper can be selected for cleaning, while for stubborn stains on the floor, a scraper with greater hardness such as a stainless steel scraper can be selected for cleaning; for fabrics with longer pile length, a brush unit with smaller brush teeth can be selected for cleaning, and for fabrics with shorter pile length, a brush unit with larger brush teeth can be selected for cleaning.

[0061] For different cleaning areas or cleaning objects, different cleaning units with different cleaning units are selected for cleaning, which is convenient and fast; for example, the leather cushion on the car seat is cleaned with a cleaning cloth with small friction, which can avoid as much as possible the abrasion to the leather cushion; the dust and water stains on the car window glass are scraped off with a scraper; the dust in the gap of the car window is cleaned with a brush; and the hair on the cloth cover of the seat or the soil on the foot mat can be cleaned with a brush unit with different sizes of brush teeth.

[0062] In some embodiments, referring to Figure 3 and Figure 10 , the first side of the cleaning brush assembly is provided with a first inclined surface 104 and a second inclined surface 105 at both ends, respectively, and the acute angle α between the extension lines of the first inclined surface 104 and the second inclined surface 105 is in the range of 30°-60°. By providing inclined surfaces at both ends of the cleaning unit, different numbers of cleaning brush assemblies can be assembled when different cleaning brush assemblies are assembled together through the first mounting structure and the second mounting structure, avoiding mutual restriction between the cleaning brush assemblies, and thus it is difficult to form a cleaning brush with different cleaning surfaces (cleaning units) at different angles.

[0063] In some embodiments, the second side of the main body is provided with a protrusion, so that the second side of the main body is wavy, and the wavy structure is more ergonomic during the process of cleaning by the user holding the cleaning brush assembly or the cleaning brush combined by a plurality of cleaning brush assemblies, facilitating the user to hold.

[0064] The present embodiment provides a modular cleaning brush assembly, so that the user can select one or more cleaning brush assemblies for combination according to needs during use, and then different cleaning units are provided on the plurality of cleaning brush assemblies to form a multifunctional cleaning brush, which can meet the diversified needs in daily cleaning process.

[0065] Embodiment two

[0066] For the case of cleaning the car, the common cleaning parts include smooth surfaces such as car windows, rough surfaces such as cloth seat cushions, and rougher surfaces such as floor mats. If a traditional cleaning brush with single function is used, it is difficult to cover multiple cleaning surfaces with diversity. At this time, if multiple different cleaning brushes are used for cleaning, on the one hand, more storage space is occupied, and the cleaning tool needs to be frequently replaced during use, which is troublesome. Therefore, the application provides a detachable portable multifunctional cleaning brush, multiple different cleaning modules are designed in an integrated manner, and multiple modules are connected by quick release, which is convenient to use and easy to replace.

[0067] Specifically, referring to Figures 1-3 , Figure 10 and Figure 11 :

[0068] The embodiment provides a portable multifunctional cleaning brush, referring to Figures 1-3 , comprising a connecting assembly, a first cleaning module, a second cleaning module and a third cleaning module;

[0069] The first cleaning module, the second cleaning module and the third cleaning module are connected in sequence through the connecting assembly 2 and form a triangular structure with a through hole in the center, and different cleaning units 3 are arranged on the three sides of the triangular structure respectively;

[0070] The first end of the first cleaning module, the second cleaning module and the third cleaning module is respectively provided with a first mounting structure 102, and the second end is respectively provided with a second mounting structure 103;

[0071] The first mounting structure 102 of any one of the cleaning modules 1 and the second mounting structure 103 of another cleaning module 1 are connected by quick release through the connecting assembly 2;

[0072] Specifically, the second mounting structure of the first cleaning module, the first mounting structure of the second cleaning module, the second mounting structure of the second cleaning module and the first mounting structure of the third cleaning module are connected by quick release through three connecting assemblies respectively.

[0073] In some embodiments, the shape structures of the first cleaning module, the second cleaning module and the third cleaning module are all the same, and herein, the first cleaning module, the second cleaning module and the third cleaning module are also referred to as cleaning modules. The cleaning module includes the cleaning brush assembly and the cleaning unit in embodiment one.

[0074] In some embodiments, referring to Figure 2The first mounting structure is provided with a first through hole 21 in a first direction, the second mounting structure is provided with a clamping groove 22 in a second direction, and the second mounting structure is provided with a second through hole 31 matched with the first through hole 21 in the first direction; wherein the first direction and the second direction are perpendicular;

[0075] When the first mounting structure is inserted into the clamping groove in the second direction, the second mounting structure limits the first mounting structure in the first direction; when the connecting assembly is sequentially inserted into the second through hole and the first through hole, the connecting assembly and the second mounting structure cooperate to limit the first mounting structure in the second direction.

[0076] In some embodiments, referring to Figure 2 At least one side of the first mounting structure is provided with a clamping block 22, and the edge of the second mounting structure is provided with a clamping tooth 32 matched with the clamping block; when the first mounting structure is inserted into the clamping groove in the second direction, and the clamping block 22 is inserted into the clamping tooth 32, the second mounting structure limits the first mounting structure in the first direction, and the clamping tooth 32 limits the clamping block 22 in the circumferential direction.

[0077] In some embodiments, both sides of the first mounting structure are provided with clamping blocks, and correspondingly, the edge of the second mounting structure is provided with two clamping teeth, and the two clamping teeth are located on both sides of the clamping groove.

[0078] In some embodiments, referring to Figure 2 The second mounting structure includes an upper plate 33 and a lower plate 34 located on both sides of the clamping groove, and the upper plate 33 and the lower plate 34 are respectively provided with a first sub-through hole and a second sub-through hole, and the first sub-through hole, the clamping groove and the second sub-through hole are communicated to form the second through hole 31.

[0079] Referring to Figure 1 The connecting assembly is a pressing type connecting assembly, which includes an upper pressing key 201, an elastic member 202 and a lower pressing key 203 arranged in sequence from top to bottom, the bottom of the upper pressing key 201 and the top of the lower pressing key 203 respectively extend outward to form an upper limiting edge and a lower limiting edge, and the bottom edge of the first through hole extends inward to form a limiting plate;

[0080] When the pressing type connecting assembly is installed in the first through hole, and the upper pressing key and the lower pressing key are pressed at the same time, the elastic member is compressed, so that the pressing type connecting assembly and the first mounting structure can enter the clamping groove in the second direction at the same time;

[0081] When the upper pressing key and the lower pressing key are released, the elastic member is reset, so that the lower limiting edge abuts against the limiting plate, the upper limiting edge abuts against the lower surface of the upper plate, and at least part of the upper pressing key extends out of the first sub-through hole and at least part of the lower pressing key extends out of the second sub-through hole;

[0082] When the upper pressing key and the lower pressing key are pressed at the same time, the elastic member is compressed, the upper pressing key enters the clamping groove through the first through hole, and the lower pressing key enters the clamping groove through the second through hole, so that the pressing type connecting assembly and the first mounting structure can be taken out from the second mounting structure synchronously.

[0083] In use, by pressing the upper pressing key and the lower pressing key arranged above and below at the same time, the connecting assembly can be compressed, so that the connecting assembly and the first mounting structure can enter the clamping groove synchronously; when the force on the upper pressing key and the lower pressing key is removed, the upper pressing key and the lower pressing key rebound under the action of the elastic member, and part of the upper pressing key and the lower pressing key respectively extends out of the first through hole and the second through hole to fix the two; when one of the cleaning units in the cleaning brush is damaged or needs to be replaced by a cleaning unit of a different shape, the corresponding first mounting structure can be pulled out of the clamping groove by pressing the upper pressing key and the lower pressing key again, which is convenient and fast.

[0084] In some embodiments, the cleaning unit is one of a cleaning cloth, a spatula with different hardness, and a brush unit with different pitch. Of course, the cleaning unit can also be selected in other shapes, and the present embodiment only gives a few examples and cannot limit the present application.

[0085] In some embodiments, referring to Figure 3 , the first side of the cleaning module is provided with a first inclined surface 104 and a second inclined surface 105 at both ends, respectively, and the included angle α between the extension lines of the first inclined surface 104 and the second inclined surface 105 is in the range of 30°-60°.

[0086] In some embodiments, the second side of the cleaning module extends to the center of the triangular structure to form a protrusion, so that the three sides of the perforation are all wavy.

[0087] In some embodiments, the pressing type connecting assembly further comprises a gasket provided with an opening, and the gasket is sleeved on the upper pressing key; when the pressing type connecting assembly passes through the first through hole and the second through hole in sequence, the lower limiting edge abuts against the limiting plate, and the gasket is located between the upper limiting edge and the lower surface of the upper plate.

[0088] In some embodiments, the cleaning unit is detachably arranged on the cleaning module. In other embodiments, the cleaning unit is fixedly arranged on the cleaning module.

[0089] In summary, the present application provides a modular quick-release scheme. Three cleaning modules with different cleaning units are combined and quickly fixed in a head-to-tail manner to form a triangular whole. The cost is low, the carrying is convenient, and the diversified needs of daily cleaning of vehicles can be met.

The first mounting structure 102 of any one of the two adjacent cleaning modules and the second mounting structure 103 of the other cleaning module are quickly released and connected by the connecting assembly, so that the at least four cleaning modules form a polygonal structure with a through hole in the center. Each side of the polygonal structure is provided with a different cleaning unit.

[0095] In some embodiments, the cleaning module adopts the cleaning module in Embodiment Two, that is, it comprises the cleaning brush assembly and the cleaning unit in Embodiment One.

[0096] In some embodiments, referring to Figure 4 and Figure 5 , the cleaning module 1 is four, and the four cleaning units 3 include a cleaning cloth, a spatula, and two brush units with different tooth pitches.

[0097] In other embodiments, referring to Figure 6 and Figure 7 , the cleaning module 1 is five, and the five cleaning units include a cleaning cloth 301, a spatula 302, two brush units 303 with different tooth pitches, and a cleaning gripper 304.

[0098] In some embodiments, referring to Figure 8 and Figure 9 , the cleaning gripper includes an extension 41 and a bent portion 42, and a plurality of anti-slip teeth 43 are arranged on the bent portion 42.

[0099] The extension extends outward along the first side of the main body to form a cleaning rod with a certain length, and the bent portion is bent in sequence along the height direction (Z-axis direction) of the main body and then along the width direction (X-axis direction) of the main body to form a hook shape with an opening facing the main body. When the cleaning gripper is inserted into a furniture gap (such as a sofa gap), the opening structure of the bent portion can carry out the debris (such as cookie crumbs) in the gap.

[0100] In some embodiments, the bent portion is made of a flexible material, such as silicone. By arranging a flexible bent portion, the damage of furniture by the gripper during the force application process can be effectively avoided.

[0101] In some embodiments, the second side of the cleaning module extends to the center of the polygonal structure to form a protrusion, so that each side of the perforated polygonal structure is wavy.

[0102] In view of the wider types of household cleaning areas, the present application provides another cleaning brush. The cleaning brush has at least four cleaning units with different shapes, and the cleaning modules corresponding to different cleaning units are quickly connected. In the case of damage to one of the cleaning brush assemblies, or when it is necessary to replace cleaning units with different shapes, the damaged cleaning brush assembly can be quickly disassembled and replaced through the connection assembly.

[0103] In summary, the present application provides a modular quick-release scheme. Four or more cleaning modules with different cleaning units are combined in any way and quickly fixed in a polygonal whole in a head-to-tail manner. The cost is low, the use is convenient, and the diversified needs of daily household cleaning can be met.

[0104] Specifically, the present application can quickly realize the connection of the multiple cleaning modules by setting different cleaning units on different cleaning modules and setting the first mounting structure and the second mounting structure which cooperate with each other at both ends of the cleaning module.

[0105] Further, the present application can ensure the connection stability between the two mounting structures and the connection stability between the adjacent two cleaning modules by setting multiple limiting structures to limit the two mounting structures in all directions. Wherein, the clamping groove structure of the second mounting structure can limit the first mounting structure in the first direction (Z-axis direction) when the first mounting structure and the second mounting structure are connected, and the connecting assembly inserted into the first through hole and the second through hole can limit the first mounting structure in the second direction (perpendicular to the Z-axis direction); in addition, the present application also limits the first mounting structure in the circumferential direction by the cooperation of the clamping block and the clamping tooth.

[0106] Further, the present application sets the quick-release connecting assembly of the pressing type, which can compress the connecting assembly by pressing the upper pressing key and the lower pressing key arranged above and below at the same time during use, so that the connecting assembly and the first mounting structure can be synchronized into the clamping groove; when the force on the upper pressing key and the lower pressing key is removed, the upper pressing key and the lower pressing key rebound under the action of the elastic member, and a part of the upper pressing key and the lower pressing key respectively extends out of the first through hole and the second through hole to fix them; when one of the cleaning units in the cleaning brush is damaged or needs to be replaced by a cleaning unit of different shape, the corresponding first mounting structure can be pulled out of the clamping groove by pressing the upper pressing key and the lower pressing key again, which is convenient and fast.
