Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and together with the description serve to explain the principles of the invention, and are not intended to limit the scope of the invention.
In describing embodiments of the present invention, it should be noted that, unless explicitly stated and limited otherwise, the term "coupled" should be interpreted broadly, for example, as being fixedly coupled, as being detachably coupled, as being integrally coupled, as being mechanically coupled, as being electrically coupled, as being directly coupled, as being indirectly coupled via an intermediate medium. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.
The terms "top," "bottom," "above … …," "below," and "on … …" are used throughout the description to refer to the relative positions of components of the device, such as the relative positions of the top and bottom substrates inside the device. It will be appreciated that the devices are versatile, irrespective of their orientation in space.
For convenience of explanation, it is specified that when the cleaner is stably placed on a horizontal plane, a surface contacting with the horizontal plane is a bottom surface of the cleaner, and the up-down direction of the cleaner is defined by the bottom surface, and at this time, a suction pipe of the cleaner faces to the front of the cleaner, and the front-back direction of the cleaner is defined by the suction pipe.
Example 1
As shown in fig. 2 to 7, the embodiment of the present invention provides a detachable cyclone filtration structure comprising an inner housing 1 and a cyclone filtration assembly; the cyclone filter component is connected with the inner shell 1 through a disassembly and assembly structure; the dismounting structure comprises mutually matched assembling grooves and assembling blocks 3, the assembling blocks 3 are arranged on the inner shell 1 or the cyclone filtering assembly, and the assembling blocks 3 are at least partially arranged along the radial direction. The inner shell 1 is used as a mounting carrier of the cyclone filter assembly, and considering that the cyclone filter assembly needs to generate stable cyclone, the main body of the cyclone filter assembly and the main body of the inner shell 1 are in rotationally symmetrical form, the inner shell 1 and the cyclone filter assembly are coaxially arranged, at least one part of the equipment groove and the assembly block 3 are radially arranged, and the limit can be effectively formed in the vertical radial axial direction to prevent the cyclone filter assembly from falling off from the inner shell 1.
It should be noted that the fitting groove and the fitting block 3 are in correspondence: if the fitting groove is provided on the inner housing 1, the fitting block 3 is provided on the cyclone filter assembly; if the fitting groove is provided on the cyclone filter assembly, the fitting block 3 is provided on the inner housing 1.
After the inner shell 1 and the cyclone filter assembly are installed, in order to improve the axial firmness, in the embodiment of the invention, a plurality of assembly blocks 3 are arranged on the annular support 2 at the air outlet end of the cyclone filter assembly and are uniformly distributed circumferentially around the axis of the cyclone filter assembly. The mounting blocks 3 are arranged on the annular support 2, so that the influence of the mounting blocks 3 on the original functions of the cyclone filter assembly can be avoided. Illustratively, in the embodiment of the present invention, the annular support 2 may be an annular cylindrical structure sleeved on the air outlet end of the cyclone filter assembly, or an integral structure with the air outlet end of the cyclone filter assembly. The assembly blocks 3 which are uniformly distributed in the circumferential direction can lead the connection of the inner shell 1 and the cyclone filter component to be more uniform in stress of each assembly block 3 in the circumferential direction, and prevent individual assembly blocks 3 from being singly damaged due to the overlarge acting force.
In the embodiment of the present invention, the assembly blocks 3 are radially arranged on the annular support 2, or are of inward protruding structures or outward protruding structures, but in consideration of the fact that if the cyclone filter assembly is detached for cleaning, the outward protruding assembly blocks 3 are easily hooked on articles such as rags and the like, and possibly rubbed against a user, so in the embodiment of the present invention, the assembly blocks 3 are radially inwardly arranged on the inner side of the annular support 2.
In order to avoid the situation that axial dislocation occurs when the cyclone filter assembly and the inner shell 1 are installed, in the embodiment of the invention, the inner shell 1 comprises an annular outer wall 12 and an annular inner wall 11 which are arranged at the air inlet end of the inner shell 1; the annular holder 2 can be inserted into the fitting region 13 between the annular outer wall 12 and the annular inner wall 11. The annular assembly area 13 between the annular outer wall 12 and the annular inner wall 11 not only can ensure that the cyclone filter assembly and the inner shell 1 can be coaxially installed, but also can prevent the axial deviation of the cyclone filter assembly and the inner shell 1 caused by vibration or external action after the cyclone filter assembly and the inner shell 1 are installed.
Since the fitting block 3 is provided radially inward of the annular bracket 2, in order to enable the fitting groove and the fitting block 3 to be smoothly fitted, the fitting groove is provided on the annular inner wall 11 in the embodiment of the present invention. If the fitting block 3 is disposed radially outward of the ring-shaped holder 2, the fitting groove is provided on the ring-shaped outer wall.
In order to prevent the assembly block 3 from falling off after being matched with the assembly groove, in the embodiment of the invention, the assembly groove comprises an assembly hole 4 penetrating through an annular inner wall 11, the side wall of the assembly hole 4 protrudes outwards along the radial direction, and a certain gap is required to be reserved between the annular inner wall 11 and the annular shape in order to prevent interference with the assembly block 3 which is inwards in the radial direction, so that the assembly hole 4 which is outwards in the radial direction can be matched with the assembly block 3 better; the lateral wall of pilot hole 4 is equipped with the opening of circumference, and pilot block 3 can follow the opening and slide in pilot hole 4, and pilot block 3 is along rotating along with whirlwind filter unit circumference, and pilot block 3 slides in the pilot groove from the opening, realizes the cooperation of pilot block 3 and pilot groove.
In the embodiment of the present invention, the assembly hole 4 is approximately a rectangular hole, and the assembly hole 4 is mainly a first sidewall 41, a second sidewall 42 and a third sidewall that contribute to the cooperation of the assembly block 3 and the assembly hole 4, specifically as follows:
the opening is formed in the first side wall 41, the second side wall 42 is a side wall opposite to the first side wall 41, the first side wall 41 and the second side wall 42 are both radially arranged, and the radial width of the first side wall 41 is smaller than that of the second side wall 42; the opening is provided at a radially outward end of the first side wall 41, and a circumferential projection of the first side wall 41 and the opening on the second side wall 42 coincides with the second side wall 42. Since the assembly block 3 is located outside the annular inner wall 11, the opening is provided at the radially outer end of the first side wall 41, so that the assembly can be smoothly slid into the assembly hole 4, and the second side wall 42 can limit the assembly block 3 slid into the assembly hole 4, so as to prevent the assembly block 3 from excessively rotating along with the cyclone filter assembly. The side wall of the fitting hole 4 in sliding contact with the fitting block 3 is a third side wall which is directly connected to both the first side wall 41 and the second side wall 42 and includes a first flat portion 44 and a first guide portion 43. The first plane portion 44 is perpendicular to the first side wall 41 and the second side wall 42, so that the first plane portion 44 is a plane with a vertical axis, when the assembly block 3 rotates along with the cyclone filter assembly in the circumferential direction, the first plane portion 44 does not interfere with the movement of the assembly block 3, and meanwhile, due to the fact that the first plane portion 44 contacts with the assembly block 3, the assembly block 3 can be prevented from falling off in the axial direction by the first plane portion 44, and the inner shell 1 and the cyclone filter assembly are more firmly installed in the axial direction. The first guiding part 43 and the first plane part 44 are obtuse angles, and the axial length of the first side wall 41 is greater than that of the second side wall 42, so that the axial length of the opening part is greater, and the assembly block 3 can conveniently slide into the assembly groove from the opening part.
Accordingly, in the embodiment of the present invention, the fitting block 3 is approximately a rectangular protrusion, and the main contact surface contributing to the fitting of the fitting block 3 and the fitting hole 4 is specifically as follows:
the contact surface is the surface of the assembly block 3 in sliding contact with the assembly hole 4. The contact surface includes a second flat surface portion 32 and a second guide portion 31: the second plane part 32 is parallel to the first plane part 44, and when the assembly block 3 is matched with the assembly hole 4, the second plane part 32 is contacted with and pressed against the first plane part 44, so that the assembly block 3 can be prevented from falling off along the axial direction, and the inner shell 1 and the cyclone filter assembly are more firmly installed along the axial direction; the second guiding portion 31 is parallel to the first guiding portion 43, so that the front end thickness of the fitting block 3 is smaller than the thickness corresponding to the second plane portion 32, when the fitting of the fitting block 3 and the fitting hole 4 is performed, the front end of the fitting block 3 first enters the opening portion, and at this time, the first guiding portion 43 contacts with the second guiding portion 31 and forms both circumferential guiding and axial guiding, so that the fitting block 3 can smoothly enter the fitting hole 4.
It is considered that the cyclone filter assembly may be rotated in a circumferential direction due to vibration or cyclone of the cleaner when the cleaner is operated, so that the assembly block 3 and the assembly hole 4 slip. In order to avoid the above situation, in the embodiment of the present invention, the first plane portion 44 is provided with a radially extending groove, the second plane portion 32 is provided with a protrusion capable of being matched with the groove, and when the assembly block 3 and the assembly hole 4 are completely installed, the protrusion is clamped into the groove, so as to prevent the assembly block 3 and the assembly hole 4 from generating relative motion in the circumferential direction, and further prevent the cyclone filter assembly from falling off due to circumferential rotation, and a user only needs to overcome the rated resistance of the protrusion falling off from the groove to detach the cyclone filter assembly from the inner housing 1.

The embodiment of the invention provides a method for disassembling a cyclone filter assembly, which is used for disassembling the cyclone filter assembly with the detachable cyclone filter structure in the embodiment 1 from an inner shell 1.
The mounting method comprises the following steps:
s1, installing an annular bracket 2 of the cyclone filter assembly in an assembly area 13;
s2, rotating the cyclone filter assembly around the axis of the cyclone filter assembly to enable the assembly block 3 to be inserted into the opening part, and enabling the first guide part 43 to be in contact with the second guide part 31;
s3, continuing to rotate the cyclone filter assembly until the grooves of the first plane parts 44 of the protrusions of the second plane parts 32 are matched, and completing the installation of the cyclone filter assembly.
The disassembly method and the installation method are reciprocal, and the steps comprise:
s1, rotating the cyclone filter assembly to disengage the grooves of the convex first plane parts 44 of the second plane parts 32;
s2, continuing to rotate the cyclone filter assembly until the assembly block 3 is separated from the opening part;
s3, taking down the cyclone filter assembly along the axial direction, so that the annular support is separated from the assembly area 13 between the annular outer wall 12 and the annular inner wall 11, and the cyclone filter assembly is detached.
The whole disassembly and assembly process is simple and convenient.
