Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner which is convenient to assemble and disassemble. Background Art

[0002] A vacuum cleaner is a machine that uses an electric motor to generate negative air pressure. It is mainly used to absorb dust. It can be divided into vertical, horizontal and portable types according to its structure. Industrial vacuum cleaners collect waste, filter and purify air during industrial production processes, while household vacuum cleaners are used for household cleaning. The working principle of a vacuum cleaner is that the electric motor drives the blades to rotate at high speed, generating negative air pressure in the sealed shell, thereby sucking away dust.

[0003] For example, Chinese patent CN219516110U discloses a segmented dust mop that is easy to disassemble and assemble, including a mop head, a dust suction body and a mop rod. The mop head is hinged to the lower end of the dust suction body, and a dust suction port for dust suction is provided at the bottom of the mop head. The dust suction port is connected to the inlet of the dust suction body through a hose. The dust suction body includes an upper body and a lower body that are arranged in upper and lower parts. The lower end of the lower body is hinged to the mop head, and the upper end of the lower body is detachably connected to the upper body through a clamping structure. When the upper body is connected to the lower body, it can rotate around the rotation axis to switch between the clamping position and the release position. When the upper body is rotated to the clamping position, the upper body is fixed relative to the lower body along the extension direction of the rotation axis.

[0004] However, when the existing small household vacuum cleaners are in use, the vacuum rod and the vacuum body are usually connected by a spiral screw. Although this assembly method can achieve general installation and disassembly during use, it will cause different degrees of wear between the vacuum rod and the vacuum body after multiple spiral frictions, resulting in the assembly between the vacuum rod and the vacuum body being not firm enough, resulting in loosening and falling off during use. In severe cases, the connection part between the vacuum rod and the vacuum body will be damaged and cannot be used normally. In view of the above problems, a vacuum cleaner that is easy to disassemble and assemble is proposed. Utility Model Content

[0025] The specific configuration and function of this embodiment are described in detail below: When the dust collecting component 2 and the telescopic component 3 need to be assembled, as shown in FIG. Figure 4As shown, the user only needs to press the pressing protrusion 28 with the thumb and push the pressing protrusion 28 inward to make the internal movable plate 27 slide along the slide plate 25, thereby driving the limiting protrusion 29 to move to the inside of the connecting head 22. At this time, align one end of the connecting head 22 with one end of the telescopic rod 31 of the telescopic assembly 3 for installation, move the protrusion 23 and the limiting protrusion 29 to the inside of the telescopic rod 31 until the plug block 36 is plugged and fixed with the protrusion 23. At this time, the thumb releases the pressing protrusion 28, and the movable plate 27 automatically slides to its original position under the elastic force of the spring 26, so that the limiting protrusion 29 is moved to the inside of the telescopic rod 31. One end of the protruding rod 29 extends out of the connecting head 22 and the limiting hole 37, and the insert block 36 can limit the horizontal rotation of the connecting head 22. At the same time, the limiting protruding rod 29 limits and fixes the connecting head 22 and the telescopic rod 31, thereby improving the assembly firmness between the dust collection component 2 and the telescopic component 3, and achieving the purpose of convenient and quick installation or disassembly of the dust collection component 2 and the telescopic component 3. Different from the traditional assembly method of connecting with spiral screws, it reduces the problem of easy wear of the assembly parts of the dust collection component 2 and the telescopic component 3, and avoids the loosening and falling off of the telescopic component 3 during use.

[0026] Embodiment 2

[0027] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the utility model provides a vacuum cleaner that is easy to disassemble and assemble. The telescopic assembly 3 includes a telescopic rod 31, a sleeve rod 33, a handle 34, an assembly rod 35, a fixing plate 38, a mounting rod 39 and a pull ring 40. The outer wall of the telescopic rod 31 is evenly provided with a plurality of through holes 32. One end of the assembly rod 35 is fixedly connected to one end of the sleeve rod 33, the outer side of the assembly rod 35 is fixedly connected to one end of the fixing plate 38, the outer wall of the mounting rod 39 is slidably installed with the inner wall of the fixing plate 38, and the mounting rod 39 is fixedly connected to the outer wall of the fixing plate 38. One end is fixedly installed with one end of the pull ring 40, a spring 2 41 is arranged on the inner side of one end of the fixing plate 38, one end of the spring 2 41 is fixedly connected with one end of the mounting rod 39, the inner wall of the sleeve rod 33 is symmetrically provided with sliding grooves 42, one end of the telescopic rod 31 passes through the assembling rod 35 and is slidably installed with the inner wall of the sliding groove 42, an insert block 36 is fixedly installed on the inner wall of one end of the telescopic rod 31, and a limiting hole 37 is arranged on the outer wall of one end of the telescopic rod 31, and one end of the sleeve rod 33 is fixedly installed with one end of the handle 34.

[0028] The effect achieved by the entire embodiment is that when the user needs to adjust the length of the telescopic component 3 according to the needs, Figure 6As shown, the user manually pulls the pull ring 40 to move the mounting rod 39 outward along the inner side of the fixing plate 38 to exit the telescopic rod 31. At this time, the telescopic rod 31 can slide along the inner wall of the sleeve rod 33. The user adjusts the length of the telescopic rod 31 and aligns the through hole 32 here with the mounting rod 39. After alignment, the pull ring 40 is released. Under the elastic force of the spring 41, one end of the mounting rod 39 passes through the through hole 32 and moves to the inside of the telescopic rod 31, thereby limiting the telescopic rod 31. In this way, the telescopic assembly 3 can be flexibly extended and adjusted in length as needed, which is convenient for users of different heights to use. It has a wide range of applicability, convenient adjustment operation, easy use and strong practicality.

[0029] The use method and working principle of the device: The small household vacuum cleaner is composed of a working suction head 1, a dust suction component 2 and a telescopic component 3. Figure 1 As shown, the bottom end of the dust suction component 2 is rotatably mounted with one end of the working suction head 1, and the top end of the dust suction component 2 is connected with one end of the telescopic component 3. When the user needs to use the vacuum cleaner to clean the floor, the dust suction component 2 and the telescopic component 3 need to be assembled first. After the assembly, the length of the telescopic component 3 is adjusted according to the needs, and the working suction head 1 is placed in contact with the floor. The handle 34 is held to push the vacuum cleaner to move on the floor to clean the floor.

[0030] When the dust collecting assembly 2 and the telescopic assembly 3 need to be assembled, Figure 4 As shown, the user only needs to press the pressing protrusion 28 with the thumb and push the pressing protrusion 28 inward to drive the limiting protrusion 29 to move into the inside of the connecting head 22. At this time, the protrusion 23 and the limiting protrusion 29 are moved into the inside of the telescopic rod 31 until the plug block 36 is plugged and fixed with the protrusion 23. At this time, the pressing protrusion 28 is released, so that one end of the limiting protrusion 29 extends out of the connecting head 22 and the limiting hole 37. The plug block 36 can limit the horizontal rotation of the connecting head 22. At the same time, the limiting protrusion 29 limits and fixes the connecting head 22 and the telescopic rod 31, thereby improving the assembly firmness between the dust collection component 2 and the telescopic component 3, and achieving the purpose of convenient and quick installation or removal of the dust collection component 2 and the telescopic component 3. Different from the traditional assembly method of connecting with spiral screws, the problem of easy wear of the assembly parts of the dust collection component 2 and the telescopic component 3 is reduced.

[0031] At the same time, by setting the telescopic component 3, when the user needs to adjust the length of the telescopic component 3 according to the needs, such as Figure 6As shown, the user manually pulls the pull ring 40 to move the mounting rod 39 outward along the inner side of the fixing plate 38 to extend the telescopic rod 31. At this time, the user adjusts the length of the telescopic rod 31 and aligns the through hole 32 here with the mounting rod 39. After alignment, the pull ring 40 is released. Under the elastic force of the spring 41, one end of the mounting rod 39 passes through the through hole 32 and moves to the inside of the telescopic rod 31, thereby limiting the telescopic rod 31, so that the telescopic assembly 3 can be flexibly extended and adjusted in length as needed, which is convenient for users of different heights to use.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
