Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, in particular to an electric vacuum cleaner for removing hair, dust and other substances on the surface of an object. Background Art

[0002] In daily life, impurities such as human hair, pet hair, fluff, dust, etc. are attached to the surfaces of clothing and furniture, which are usually removed by vacuum cleaners. Currently, most vacuum cleaners are gun-type vacuum cleaners and pet hair vacuum cleaners.

[0003] Among them, gun-type vacuum cleaners mostly remove impurities through brush heads and suction heads. In the process of removing impurities, the brush head sweeps or rolls up the impurities, and then sucks the impurities into the cavity through the suction head. In the process of removing impurities, there is a problem of hair entangled in the brush head, making the brush head difficult to clean, and even clogging the vacuum cleaner, requiring the brush head or suction head to be replaced.

[0004] Among them, pet hair vacuum cleaners use the principle of static electricity to absorb pet hair shed onto the surface of objects, and then collect it into a collection chamber. Since this type of suction head does not have a self-cleaning function, it is easy to bring hair out of the collection chamber, affecting the hair removal effect.

[0005] At the same time, gun-type vacuum cleaners and pet hair vacuum cleaners also use suction to absorb impurities attached to the surface. They are more effective in removing smaller impurities, but as the particle size of the impurity particles increases, the required suction force also increases. As the vacuum cleaner continues to work, its adsorption effect will continue to decay, resulting in a decrease in the impurity removal effect. At the same time, some objects have electrostatic adhesion on the surface due to the influence of their material, which will also affect the normal operation of the vacuum cleaner and the impurity removal effect.

[0006] Therefore, it is necessary to improve the existing vacuum cleaner. Summary of the invention

[0007] In order to solve the problems that, when existing vacuum cleaners suck impurities such as hair and dust on the surface of objects, hair is easily entangled on the suction head, the suction force is weakened, and impurities are brought out of the dust collecting space, the present invention designs an electric vacuum cleaner with a simple structure and easy assembly. The vacuum cleaner can be held by hand and moved back and forth (reciprocating / forward and backward) on the surface of an object to remove impurities on the surface of the object and collect them in a receiving chamber. During the operation of the vacuum cleaner, impurities will not be brought out of the receiving chamber, thereby ensuring the removal effect of impurities.

[0008] The technical solution for achieving the purpose of the invention is as follows: an electric vacuum cleaner comprises a suction head and a handheld part, the suction head is assembled in the handheld part, and the suction head comprises a shell, a suction head structure, and a peeling structure.

[0009] The suction head structure is installed in the working area of ​​the shell. When the suction head structure contacts the surface of the object and moves on the surface of the object, it performs forward and reverse reciprocating motion in the working area to transfer impurities on the surface of the object to the suction head structure.

[0010] The stripping structure is arranged on the inner wall of the operating area of ​​the shell, and the stripping structure is in contact with the suction head structure, and is used to strip impurities from the suction head structure when the suction head structure rotates forward or reversely.

[0011] Among them, a power structure is provided in the handheld part, and the power structure is used to generate and output suction force to the working area to suck the peeled impurities into the containing cavity.

[0012] The principle of the electric vacuum cleaner of the present invention is: when the electric vacuum cleaner is placed on the surface of an object and contacts the surface of the object, under the action of friction, the suction head structure rotates back and forth to adhere impurities on the surface of the object, the peeling structure peels off the impurities adhered to the suction head structure, and the power structure sucks the peeled impurities into the accommodating cavity, thereby achieving a good effect of removing impurities on the surface of the object.

[0013] The process of removing impurities on the surface of an object by the electric vacuum cleaner of the present invention is as follows: first, a shell, a suction head structure, and a stripping structure of a separately designed structure are assembled to form a suction head portion, and the suction head portion is installed on a handheld portion; second, the electric vacuum cleaner is held in the hand, so that the suction head structure contacts the surface of the object, and when the suction head structure is moved, the suction head structure contacts the surface of the object to generate friction, and under the action of the friction, the suction head structure moves forward (or reverse) in the working area to transfer impurities on the surface of the object to the suction head structure; then, the position on the suction head structure where impurities are adsorbed is forward (or reverse) rotated into the working area, and when it is reversed (or forward) rotated out, the impurities on the suction head structure are stripped off through the stripping structure; finally, the stripped impurities are sucked into the accommodating cavity by the suction force generated by the power structure.

[0014] In one embodiment of the present invention, the suction head structure includes a support portion, the support portion is a columnar or arc-shaped structure, and a bonding surface is provided on the outer peripheral wall of the columnar or arc-shaped structure.

[0015] The bonding surface comprises a first bonding surface, on which a first bonding structure is arranged, and the first bonding structure is used to adhere impurities on the surface of the object.

[0016] In a preferred embodiment of the present invention, the bonding surface further includes a second bonding surface, and the second bonding surface is located on both sides of the first bonding surface.

[0017] Wherein, a second adhesive structure is provided on the second adhesive surface, and the second adhesive structure is used for peeling off impurities adhered to the structure.

[0018] Furthermore, the area of ​​the bonding surface is larger than the area of ​​the window of the working area.

[0019] In a preferred embodiment of the present invention, the upper and lower ends of the support part are assembled to the housing via shafts, and the shafts are used to enable the support part to achieve forward and reverse rotation in the working area.

[0020] In a preferred embodiment of the present invention, the suction head structure further includes a friction portion, and the friction portion is arranged on the bonding surface.

[0021] In one embodiment of the present invention, the forward and reverse rotation angles of the suction head structure in the working area are both 30-170°.

[0022] In one embodiment of the present invention, the stripping structure includes stripping components with the same structure and symmetrically arranged on the inner wall of the working area.

[0023] The stripping assembly includes a first stripping plate, which is used to closely contact the suction head structure and strip impurities on the suction head structure when the suction head structure rotates forward or reversely.

[0024] In a preferred embodiment of the present invention, the stripping assembly also includes a second stripping plate, which is located between the inner wall of the shell and the first stripping plate, and stripping teeth are also provided on the second stripping plate at an end away from the working area window, and the stripping teeth are used to strip impurities adhered to the suction head structure.

[0025] In one embodiment of the present invention, the housing includes an upper housing and a lower housing, the upper housing is a hollow structure, and a window for assembling the suction head structure to the working area is provided on the side of the upper housing.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The electric vacuum cleaner of the present invention absorbs impurities on the surface of an object in the form of friction + suction, achieving a better impurity removal effect. By designing the suction head structure and the peeling structure of the suction head, on the one hand, the first adhesion structure transfers impurities to the first adhesion structure by rolling on the surface of the object, and the impurities on the first adhesion structure are peeled off by the first peeling plate, and then sucked into the accommodation cavity by the power structure; on the other hand, the second adhesion structure is designed based on the first adhesion structure, which can remove a small amount of impurities that have not been sucked into the accommodation cavity on the first peeling plate, and then peel them off by the second peeling plate, so as to avoid the impurities that are brought out from adhering to the surface of the object repeatedly, thereby ensuring the removal effect of impurities on the surface of the object.

[0028] 2. The suction head structure, the peeling structure and the shell are designed to be separated, and the two are assembled into the working area of ​​the shell to facilitate the replacement and cleaning of the suction head structure and the peeling structure.

However, these embodiments are exemplary only and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements all fall within the scope of protection of the present invention.

[0043] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0044] See also Figure 1 , an electric vacuum cleaner provided by the present invention comprises a suction head portion 10 and a hand-held portion 20 , wherein the suction head portion 10 is assembled in the hand-held portion 20 .

[0045] See also Figure 2 and Figure 3 As shown, the suction head 10 includes a shell 1 , a suction head structure 2 , and a peeling structure 3 .

[0046] The suction head structure 2 is installed in the working area 100 of the shell 1. When the suction head structure 2 contacts the surface of the object and moves on the surface of the object, the suction head structure 2 performs forward and reverse reciprocating motion in the working area 100 to transfer impurities on the surface of the object to the suction head structure 2.

[0047] The stripping structure 3 is disposed on the inner wall of the operating area of ​​the housing 1 , and the stripping structure 3 is in contact with the suction head structure 2 , and is used to strip impurities from the suction head structure 2 when the suction head structure 2 rotates forward or reversely.

[0048] The power structure (not shown in the drawings) is located in the handheld portion 20, and is used to generate and output suction force to the working area 100 to suck the peeled impurities into the receiving chamber (not shown in the drawings).

[0049] The principle of the electric vacuum cleaner is: when the electric vacuum cleaner is placed on the surface of an object and contacts the surface of the object, under the action of friction, the suction head structure 2 rotates back and forth, adhering impurities on the surface of the object, the peeling structure 3 peels off the impurities adhered to the suction head structure 2, and the power structure sucks the peeled impurities into the accommodating cavity, thereby achieving a good removal effect of impurities on the surface of the object.

[0050] The process of removing impurities on the surface of an object by the electric vacuum cleaner of the present invention is as follows: first, a shell 1, a suction head structure 2, and a stripping structure 3 of a split design are assembled to form a suction head 10, and the suction head 10 is installed on a handheld part 20; second, the electric vacuum cleaner is held in hand, so that the suction head structure 2 contacts the surface of the object, and when the suction head structure 2 is moved, the suction head structure 2 contacts the surface of the object to generate friction, and under the action of the friction, the suction head structure 2 moves forward (or reversely) in the working area 100, and the impurities on the surface of the object are transferred to the suction head structure 2; then, the position where the impurities are adsorbed on the suction head structure 2 rotates forward (or reversely) into the working area 100, and when it rotates out in the reverse direction (or forward), the impurities on the suction head structure 2 are stripped off through the stripping structure 3; finally, the stripped impurities are sucked into the accommodating cavity by the suction force generated by the power structure.

[0051] The various components of the electric vacuum cleaner are described in detail below through specific examples.

[0052] Embodiment 1:

[0053] This embodiment is to explain the structure of the housing 1 of the suction head 10 of the electric vacuum cleaner.

[0054] In one structure of the housing 1, as Figure 4 As shown, the housing 1 is cylindrical and includes an upper housing 1-1 and a lower housing 1-2. The upper housing 1-1 is a hollow structure. The hollow structure forms an operating area 100 for installing the suction head structure 2. A window is provided on the side of the upper housing 1-1 for assembling the suction head structure 2 to the operating area 100.

[0055] In another structure of the housing 1, as Figure 3 As shown, the housing 1 is cylindrical and includes an upper housing 1-1, a lower housing 1-2, and a rear cover 1-3. The hollow structure forms an operating area 100 for installing the suction head structure 2. Two windows are provided on both sides of the upper housing 1-1, one of which is used to assemble the suction head structure 2 into the operating area 100; the other window is used to install the rear cover 1-3. By designing the rear cover 1-3, the purpose of removing the collected impurities and cleaning the operating area 100 can be achieved by simply opening the rear cover 1-3 without removing the suction head structure 2.

[0056] It should be noted that the two structures of the shell 1 provided above are only preferred forms of the electric vacuum cleaner and are not specifically limited thereto, as long as there is an operating area 100 in the shell 1 for installing and accommodating the suction head structure 2.

[0057] Embodiment 2:

[0058] This embodiment describes the suction head structure 2 of the suction head portion 10 of the electric vacuum cleaner. The shape of the suction head structure 2 is the same as or similar to the working area 100 of the shell 1 in Example 1. For example, the working area 100 in Example 1 is cylindrical, and the suction head structure 2 of this embodiment is a columnar or arc-shaped structure (i.e., a cylindrical shape with an arc of 180 to 360 degrees). This embodiment uses the cylindrical suction head structure 2 to specifically describe its structure.

[0059] See also Figure 5 and Figure 6 As shown, the suction head structure 2 includes a cylindrical supporting portion 2 - 1 .

[0060] The support part 2-1 may be a hollow structure or a solid structure, and is preferably made of a material that is light in weight, high in strength, and high in toughness. Figure 3 As shown, the upper and lower ends of the support part 2 - 1 are assembled to the housing 1 via shafts (upper shaft 4 and lower shaft 5 ), and the shafts (upper shaft 4 and lower shaft 5 ) are used to enable the support part to realize forward and reverse rotation in the working area 100 .

[0061] Furthermore, in order to prevent the support part 2-1 from rotating 360° in the working area 100 and being unable to remove impurities, the suction head structure 2 also includes a limiting structure (not shown in the drawings). In this embodiment, the limiting structure can be provided on the support part 2-1 and the upper shell 1-1, or on other structures. The limiting structure is used to limit the angles of the forward and reverse rotation of the support part 2-1, so that the support part 2-1 can be reversed after forward rotation to remove impurities (or can be forward rotated again after reverse rotation to remove impurities).

[0062] See also Figure 5 and Figure 6 As shown, the suction head structure 2 also includes a bonding surface located on the outer peripheral wall of the support portion 2 - 1 , and the bonding surface is used to install the adhesive structure.

[0063] The bonding surface may occupy the entire outer peripheral wall of the support portion 2 - 1 , or may be divided into one or more regions for use.

[0064] In a structure of bonding surface, such as Figure 5 and Figure 6As shown, the adhesive surface includes a first adhesive surface 2-2, and a first adhesive structure 2-3 is provided on the first adhesive surface 2-2. The first adhesive structure 2-3 is arranged on the first adhesive structure 2-3 by pasting or buckling. The first adhesive structure 2-3 can be formed of one piece or multiple pieces. When sucking impurities on the surface of an object, when the suction head structure 2 rotates forward or reversely (it can be described by clockwise rotation or counterclockwise rotation, or by left and right reciprocating rotation, etc.), the first adhesive structure 2-3 contacts the surface of the object and adheres to the impurities (hair, animal hair, debris, dust, etc.) on the surface of the object. After the first adhesive structure 2-3 adheres to the impurities on the surface of the object, it is brought into the working area 100 after the suction head structure rotates. When it is reversed (i.e., reset), the stripped structure 3 strips the impurities from the surface of the first adhesive structure 2-3, and the stripped impurities are sucked into the accommodating cavity by the suction force provided by the power structure.

[0065] Another structure of the bonding surface is an improvement of the bonding surface of the first structure. Since the peeled impurities may adhere to the peeling structure 3, the bonding surface is optimized, such as Figure 5 and Figure 6 As shown, the bonding surface includes a first bonding surface 2 - 2 and a second bonding surface 2 - 4 , which can prevent the peeling structure 3 from accumulating impurities and thus affecting the peeling effect.

[0066] Specifically, Figure 5 and Figure 6 As shown, the second adhesive surface 2-4 is located on both sides of the first adhesive surface 2-2, and a second adhesive structure 2-5 is provided on the second adhesive surface 2-4, and the second adhesive structure 2-5 is used to remove impurities adhered to the peeling structure 3. At the same time, in order to ensure that the impurities peeled off by the peeling structure 3 are sucked into the accommodating cavity in time under the action of the suction force of the power structure, a spacing is provided between the second adhesive structure 2-5 and the first adhesive structure 2-3.

[0067] More specifically, in the first adhesive structure 2-3 and the second adhesive structure 2-5, the first adhesive structure 2-3 is used to adhere to impurities on the surface of the object, and the peeling structure 3 is used to peel off the impurities on the first adhesive structure 2-3 when the first adhesive structure 2-3 is rotated out and reset; the second adhesive structure 2-5 is used to peel off a small amount of impurities attached to the peeling structure 3 that have not been sucked into the accommodating cavity. Therefore, the three can be made of flannel material or other materials. At the same time, the flannel fiber direction of the first adhesive structure 2-3 is the same as the fiber direction of the peeling structure 3, and the fiber direction of the second adhesive structure 2-5 is opposite to the fiber direction of the peeling structure 3. The peeling structure 3 peels off the impurities adhered to the first adhesive structure 2-3, and the second adhesive structure 2-5 peels off the impurities peeled off from the peeling structure 3. Since the fiber directions of the two are opposite, they can be made of materials with the same hardness. It can also be made of materials with different hardness. For example, when flannel material is selected, the hardness relationship among the first adhesive structure 2-3, the second adhesive structure 2-5, and the peeling structure 3 (specifically the first peeling plate 3-1 in Example 3) is: the flannel hardness of the second adhesive structure 2-5 ≥ the flannel hardness of the peeling structure 3 ≥ the flannel hardness of the first adhesive structure 2-3.

[0068] At the same time, since the amount of impurities adhered to the peeling structure 3 and not absorbed by the accommodating cavity is small, the second adhesive structure 2-5 is used to remove them, so the area of ​​the second adhesive structure 2-5 is smaller than that of the first adhesive structure 2-3.

[0069] In a preferred embodiment of the present invention, Figure 5 and Figure 6 As shown, the suction head structure 2 further includes a friction portion 2 - 6 , which is arranged on the bonding surface and is used to increase the friction between the suction head structure 2 and the surface of the object, so that the support portion 2 - 1 can rotate better.

[0070] Specifically, the friction parts 2-6 can be arranged in any direction, for example, they can be arranged on the bonding surface in a horizontal, vertical, or oblique direction; their structures can be in any shapes such as strips, sheets, or protrusions, as long as they can increase the friction between the suction head structure 2 and the surface of the object and facilitate the forward and reverse rolling of the suction head structure 2 in the working area 100; their materials can be non-hard materials to avoid damaging the surface of the object.

[0071] In one embodiment of the present invention, the forward and reverse rotation angles of the suction head structure in the working area are both 30-170°.

[0072] Embodiment 3:

[0073] This embodiment is to illustrate the peeling structure 3 of the suction head 10 of the electric vacuum cleaner. The peeling structure 3 provided in this embodiment cooperates with the shell of embodiment 1 and the suction head structure 2 of embodiment 2 to peel off impurities on the suction head structure 2. Figure 8 As shown, the stripping structure 3 includes stripping components with the same structure and symmetrically arranged on the inner wall of the working area.

[0074] Among them, Figure 7 and Figure 8 The stripping assembly shown includes a first stripping plate 3 - 1 , which is used to closely contact with the suction head structure 2 and strip impurities on the suction head structure 2 when the suction head structure 2 rotates forward or reversely.

[0075] Specifically, when the first adhesive structure 2-3 of the suction head structure 2 adheres to the impurities on the surface of the object, contacts the first stripping plate 3-1 and rotates into the shell 1, the first stripping plate 3-1 will not strip the first adhesive structure 2-3 because the fiber direction of the first adhesive structure 2-3 is the same as the fiber direction of the first stripping plate 3-1. When the first adhesive structure 2-3 is rotated out, the fiber direction of the first adhesive structure 2-3 is opposite to the fiber direction of the first stripping plate 3-1 because the rotation direction of the first adhesive structure 2-3 has changed, so the first stripping plate 3-1 can strip the impurities on the first adhesive structure 2-3 and then be sucked into the accommodating cavity.

[0076] At the same time, this embodiment preferably chooses to set the first peeling plate 3-1 at the edge of the window. The purpose is that as long as the first adhesive structure 2-3 passes through the first peeling plate 3-1 and is transferred into the working area 100, and then transferred out and reset, the first peeling plate 3-1 can peel off the impurities on the first adhesive structure 2-3, thereby increasing the impurity peeling area on the first adhesive structure 2-3.

[0077] When the second adhesive surface 2-4 and the second adhesive structure 2-5 are added to the suction head structure 2, since the second adhesive structure 2-5 is used to adhere the impurities on the first peeling plate 3-1 that are not sucked into the accommodation cavity by the suction force, in order to peel off the impurities on the second adhesive structure 2-5, the peeling structure 3 is improved in this specific embodiment to form a second peeling structure 3.

[0078] like Figure 7 and Figure 8 As shown, the stripping assembly includes a first stripping plate 3-1 and a second stripping plate 3-2. The second stripping plate 3-2 is located between the inner wall of the housing 1 and the first stripping plate 3-1.

[0079] Specifically, the second stripping plate 3-2 is mounted on both sides of the window of the working area 100 of the housing 1 in a snap-fitting manner, and the first stripping plate 3-1 is detachably mounted on the inner side of the second stripping plate 3-2. A stripping tooth 3-3 is further provided on the second stripping plate 3-2 at one end away from the working area window, and the stripping tooth 3-3 is used to strip the impurities adhered to the suction head structure 2 (i.e., the second adhesive structure 2-5), and then sucked into the accommodating cavity by the suction force.

[0080] Since it is necessary to ensure that the suction head structure 2 is in contact with the peeling structure 3 to achieve the peeling of impurities, in a preferred embodiment, an elastic structure (not shown in the drawings) is also provided between the peeling structure 3 and the shell 1, such as elastic rubber, spring, etc., which can realize the first adhesion structure 2-3 and the second adhesion structure 2-5 to be transferred into the working area 100 by contraction. When the first adhesion structure 2-3 and the second adhesion structure 2-5 are transferred out, it can be reset to a normal state to realize the first adhesion structure 2-3 and the second adhesion structure 2-5 to be in close contact with the peeling component to achieve the peeling of impurities.

[0081] It should be noted that the power structure of this specific embodiment is used to generate suction force, and it can adopt existing structures such as motors, or other structures, so this specific embodiment does not provide specific descriptions and limitations on this.

[0082] At the same time, in this specific embodiment, the accommodating cavity is used to store impurities peeled off from the surface of the object. It can be set in the cavity opened in the lower part of the shell 1, or it can be formed in the space between the suction head structure 2 and the working area 100 of the shell 1 by setting the suction head structure 2 to an arc shape, or it can be formed between the outer wall of the suction head structure 2 and the inner wall of the shell 1. No specific description and limitation are given here.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0084] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
