Wherein a power structure (not shown in the drawings) is located in the hand-held portion 20, and the power structure is used for generating and outputting a suction force to the working area 100, and sucking the peeled impurities into a receiving chamber (not shown in the drawings).

The principle of the electric dust collector is as follows: when electric vacuum cleaner placed at object surface and object surface contact, under the effect of frictional force, suction head structure 2 round trip rotation, with the impurity adhesion on object surface, peel off the impurity that structure 3 goes up adhesion with suction head structure 2 and peel off, the power structure holds the chamber with the impurity suction who peels off, has realized the fine effect of getting rid of object surface impurity.

The utility model discloses electric vacuum cleaner gets rid of object surface impurity's process is: firstly, assembling a shell 1, a sucker structure 2 and a stripping structure 3 which are designed in a split mode to form a sucker part 10, and installing the sucker part 10 on a handheld part 20; secondly, the electric vacuum cleaner is held by hands, so that the suction head structure 2 is contacted with the surface of the object, when the suction head structure 2 is moved, the suction head structure 2 is contacted with the surface of the object to generate friction force, and under the action of the friction force, the suction head structure 2 moves forwards (or backwards) in the operation area 100 to transfer impurities on the surface of the object into the suction head structure 2; then, the position where the impurities are adsorbed on the suction head structure 2 is rotated to the inside of the operation area 100 in a forward direction (or a reverse direction), and when the position is rotated out in a reverse direction (or the forward direction), the impurities on the suction head structure 2 are stripped through the stripping structure 3; finally, the peeled impurities are sucked into the accommodating chamber by the suction force generated by the power structure.

The components of the electric vacuum cleaner will be described in detail below by way of specific examples.

Example 1:

the present embodiment will explain the structure of the housing 1 of the suction head 10 of the vacuum cleaner.

In one configuration of the housing 1, as shown in fig. 4, the housing 1 is cylindrical and includes an upper housing 1-1 and a lower housing 1-2, and the upper housing 1-1 is hollow. Wherein the hollow structure forms a working area 100 where the nozzle structure 2 is mounted. The side of the upper housing 1-1 is provided with a window for mounting the suction head structure 2 to the working area 100.

In another structure of the housing 1, as shown in fig. 3, the housing 1 is cylindrical and includes an upper housing 1-1, a lower housing 1-2, and a rear cover 1-3. Wherein the hollow structure forms a working area 100 where the nozzle structure 2 is mounted. Two sides of the upper shell 1-1 are provided with 2 windows, wherein one window is used for assembling the suction head structure 2 into the operation area 100; the other window is used for installing the rear cover 1-3, and by designing the rear cover 1-3, the purposes of taking out the collected impurities and cleaning the operation area 100 can be realized only by opening the rear cover 1-3 under the condition that the suction head structure 2 is not taken out.

It should be noted that the housing 1 of 2 structures provided above is only a preferred form of the electric vacuum cleaner, and is not limited to a specific form, as long as the housing 1 can have the working area 100 for installing and accommodating the suction head structure 2 therein.

Example 2:

in the present embodiment, the nozzle structure 2 of the nozzle 10 of the vacuum cleaner is described, the shape of the nozzle structure 2 is the same as or similar to the working area 100 of the housing 1 in embodiment 1, for example, if the working area 100 in embodiment 1 is a cylindrical shape, the nozzle structure 2 in the present embodiment is a cylindrical or arc-shaped structure (i.e., a cylindrical shape with a radian of 180 to 360 °), and the structure of the nozzle structure 2 in the present embodiment is specifically described as a cylindrical shape.

Referring to fig. 5 and 6, the nozzle structure 2 includes a cylindrical support 2-1.

The support part 2-1 may be a hollow structure or a solid structure, and is preferably made of a material with light weight, high strength and high toughness. Since the suction head structure 2 needs to be able to rotate in the working area 100, as shown in fig. 3, the upper and lower ends of the support 2-1 are assembled to the housing 1 via shafts (the upper shaft 4 and the lower shaft 5) for rotating the support forward and backward in the working area 100.

In order to avoid the supporting portion 2-1 rotating 360 degrees in the working area 100 and the separation of the impurities cannot be achieved, the suction head structure 2 further includes a limiting structure (not shown in the drawings), in this embodiment, the limiting structure may be disposed on the supporting portion 2-1 and the upper housing 1-1, or may be disposed on other structures, and the limiting structure is used to limit the angles of the forward rotation and the reverse rotation of the supporting portion 2-1, so that the supporting portion 2-1 can rotate backward again after rotating forward to achieve the separation of the impurities (or can rotate forward again after rotating backward to achieve the separation of the impurities).

Referring to fig. 5 and 6, the suction head structure 2 further comprises an adhesive surface on the outer peripheral wall of the support 2-1 for mounting an adhesive structure.

The adhesive surface may occupy the entire outer peripheral wall of the support portion 2-1, or may be divided into 1 or more regions.

In one structure of the bonding surface, as shown in fig. 5 and 6, the bonding surface includes a first bonding surface 2-2, a first adhesion structure 2-3 is disposed on the first bonding surface 2-2, the first adhesion structure 2-3 is disposed on the first adhesion structure 2-3 by means of pasting or fastening, and the first adhesion structure 2-3 may be formed as a block or may be formed by a plurality of blocks. When the suction head structure 2 rotates forwards or backwards (can be described by clockwise rotation or anticlockwise rotation, and can also be described by left-right reciprocating rotation and the like) during the process of sucking the impurities on the surface of the object, the first adhesion structure 2-3 is in contact with the surface of the object and adheres the impurities (hair, animal fluff, debris, dust and the like) on the surface of the object. After the first adhesion structure 2-3 adheres the impurities on the surface of the object, the suction head structure is brought into the operation area 100 after rotating, and in the process of reversing (i.e. resetting), the peeled impurity structure 3 peels the impurities from the surface of the first adhesion structure 2-3, and meanwhile, the peeled impurities are sucked into the accommodating cavity by the suction force provided by the power structure.

Another structure of the adhesive surface is that the adhesive surface of the first structure is modified, and since the peeled impurities may be attached to the peeling structure 3, the adhesive surface is optimally designed, as shown in fig. 5 and 6, and includes a first adhesive surface 2-2 and a second adhesive surface 2-4, which can prevent the peeling structure 3 from gathering impurities and affecting the peeling effect.

Specifically, as shown in fig. 5 and 6, the second bonding surfaces 2-4 are located on two sides of the first bonding surface 2-2, the second bonding surfaces 2-4 are provided with second bonding structures 2-5, and the second bonding structures 2-5 are used for peeling off impurities adhered to the structure 3. Meanwhile, in order to ensure that 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 distance is reserved between the second bonding structure 2-5 and the first bonding structure 2-3.

More specifically, in the first adhesion structure 2-3 and the second adhesion structure 2-5, the first adhesion structure 2-3 is used for adhering impurities on the surface of the object, and the peeling structure 3 is used for peeling the impurities on the first adhesion structure 2-3 when the first adhesion structure 2-3 is rotated out for resetting; the second adhesion structure 2-5 is to peel off a small amount of foreign substances attached to the peeling structure 3, which are not sucked into the housing chamber. Therefore, the three materials can be selected from flannelette materials and other materials, the flannelette fiber direction of the first adhesive structure 2-3 is the same as the fiber direction of the stripping structure 3, and the fiber direction of the second adhesive structure 2-5 is opposite to the fiber direction of the stripping structure 3. The stripping structure 3 is used for stripping impurities adhered on the first adhering structure 2-3, the second adhering structure 2-5 is used for stripping impurities stripped on the stripping structure 3, and the fiber directions of the first adhering structure and the second adhering structure are opposite, so that materials with the same hardness can be selected. Materials of different hardness can also be selected. For example, when the flannelette 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 embodiment 3) is as follows: the flannelette hardness of the second adhesion structure 2-5 is larger than or equal to that of the stripping structure 3 and is larger than or equal to that of the first adhesion structure 2-3.

Meanwhile, the second adhesion structure 2-5 is used for removing impurities which are not sucked into the containing cavity and are adhered to the stripping structure 3, so that the area of the second adhesion structure 2-5 is smaller than that of the first adhesion structure 2-3.

In a preferred embodiment of the invention, as shown in fig. 5 and 6, the suction head structure 2 further comprises friction parts 2-6, and the friction parts 2-6 are arranged on the bonding surface and are used for increasing the friction force between the suction head structure 2 and the surface of the object, so that the supporting part 2-1 can better rotate.

Specifically, the arrangement direction of the friction parts 2-6 can be any direction, for example, the friction parts are arranged on the bonding surface in a transverse direction, a longitudinal direction, an oblique direction and the like; the structure can be in any shapes such as strip, sheet and bulge, and the structure can be any structure which can improve the friction force of the suction head structure 2 contacting and moving with the surface of an object and is convenient for the suction head structure 2 to roll forwards and backwards in the operation area 100; the material is non-hard material to avoid damage to the surface of the object.

Example 3:

in this embodiment, the stripping structure 3 of the suction head part 10 of the electric vacuum cleaner is explained, and the stripping structure 3 provided in this embodiment is matched with the housing of embodiment 1 and the suction head structure 2 of embodiment 2 to strip the impurities on the suction head structure 2. As shown in fig. 8, the stripping structure 3 comprises stripping assemblies which are identical in structure and symmetrically arranged on the inner wall of the working area.

Wherein, the stripping assembly shown in fig. 7 and 8 comprises a first stripping plate 3-1, and the first stripping plate 3-1 is used for closely contacting with the suction head structure 2 and stripping impurities on the suction head structure 2 when the suction head structure 2 rotates forwards or reversely.

Specifically, when the foreign matter on the surface of the first adhesive structure 2-3 of the suction head structure 2 contacts with the first peeling plate 3-1 and turns into the housing 1, the first peeling plate 3-1 does not peel off 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 peeling 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 peeling plate 3-1 due to the change of the rotation direction of the first adhesive structure 2-3, so that the first peeling plate 3-1 realizes the peeling of the impurities on the first adhesive structure 2-3 and then is sucked into the accommodating cavity.

Meanwhile, in the embodiment, the first stripping plate 3-1 is preferably arranged at the edge of the window, so that as long as the first adhesion structure 2-3 passes through the first stripping plate 3-1 and is transferred into the operation area 100, and then is transferred out for resetting, the first stripping plate 3-1 can strip the impurities on the first adhesion structure 2-3, and the impurity stripping area on the first adhesion structure 2-3 is increased.

When the suction head structure 2 is additionally provided with the second bonding surface 2-4 and the second bonding structure 2-5, the second bonding structure 2-5 is used for adhering impurities which are not sucked into the accommodating cavity by suction force on the first stripping plate 3-1, so that the impurities on the second bonding structure 2-5 are stripped. The present embodiment mode improves the peeling structure 3, and forms the second peeling structure 3.

As shown in fig. 7 and 8, the peeling assembly includes a first peeling plate 3-1 and a second peeling 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.

Specifically, the second peeling plates 3-2 are fitted to both sides of the window of the working area 100 of the case 1 in a snap-fit manner, and the first peeling plates 3-1 are detachably fitted to the inner sides of the second peeling plates 3-2. The second stripping plate 3-2 at one end far away from the window of the operation area is also provided with stripping teeth 3-3, and the stripping teeth 3-3 are used for stripping the adhered impurities on the suction head structure 2 (namely the second bonding structure 2-5) and then are sucked into the accommodating cavity by suction force.

Since it is necessary to ensure the contact between the suction head structure 2 and the stripping structure 3 to strip the impurities, in a preferred embodiment, an elastic structure (not shown in the drawings), such as an elastic rubber, a spring, etc., is further disposed between the stripping structure 3 and the housing 1, and can be contracted to enable the first adhesion structure 2-3 and the second adhesion structure 2-5 to be transferred into the working area 100, and when the first adhesion structure 2-3 and the second adhesion structure 2-5 are transferred out, they can be reset to a normal state to enable the first adhesion structure 2-3 and the second adhesion structure 2-5 to be in close contact with the stripping assembly, so as to strip the impurities.

It should be noted that the power structure of the present embodiment is used for generating the suction force, and the structure of the present embodiment, such as the motor, may be selected, and other structures may also be selected, so that the present embodiment does not specifically describe and limit this.

Meanwhile, in the present embodiment, the receiving cavity is used for storing impurities peeled off from the surface of the object, and may be disposed in a cavity formed at the lower portion of the housing 1, or may be formed in a space between the suction head structure 2 and the operation area 100 of the housing 1 by disposing the suction head structure 2 in an arc shape, or may be formed between an outer wall of the suction head structure 2 and an inner wall of the housing 1, which is not specifically described and limited herein.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
