Description

Technical Field

[0001] The present invention belongs to the general field of vacuum cleaner technology, specifically relates to household washing or cleaning, and more particularly to a handheld vacuum cleaner that is easy to store, a clamping mechanism, and a storage method. Background Art

[0002] The vacuum cleaner is folded by designing the middle connecting rod into a hinged structure, and then the main unit and the floor brush are placed on the ground at the same time by folding the connecting rod. When the vacuum cleaner is in the folded state, the hose passing through the inside of the connecting rod will be stretched, and even the hose will be folded at the hinge. In this way, when the vacuum cleaner is upright, the hose cannot recover quickly, and the hose will be clamped by the hinge point or the connection position of the connecting rod, thereby damaging the hose.

[0003] Therefore, in order to avoid the technical problem that the hose will be clamped by the hinge point of the connecting rod or the connection position of the connecting rod when the connecting rod is connected, it is necessary to design a handheld vacuum cleaner, a clamping mechanism and a storage method that are easy to store.

[0004] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art. Summary of the Invention

[0005] The embodiments of the present disclosure at least provide a handheld vacuum cleaner, a clamping mechanism, and a storage method that are easy to store.

[0006] In a first aspect, an embodiment of the present disclosure provides a handheld vacuum cleaner that is easy to store, comprising:

[0007] A pair of folding sleeves, each of which has a clamping mechanism.

[0008] A dust suction air pipe, one end of which is connected to the air source via a foldable sleeve, and the other end of which is connected to the dust suction mechanism via a foldable sleeve, and the dust suction air pipe passes through the clamping mechanism;

[0009] When the two folding sleeves are connected in the same straight line, the dust suction air pipe is bent and arranged in the folding sleeve;

[0010] When the two folding sleeves are folded, the clamping mechanism drives part of the dust suction air pipe to extend from the position where the two folding sleeves are separated, and this part of the dust suction air pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the clamped part of the dust suction air pipe into the folding sleeve so that there is no dust suction air pipe at the connection position of the two folding sleeves.

[0011] In an optional embodiment, the clamping mechanism includes: a fixing ring;

[0012] The fixing ring is arranged on the inner wall of the folding sleeve;

[0013] The fixing ring is provided with a plurality of clamping holes, which are provided along the thickness direction of the fixing ring and are tapered, with the area of the clamping holes becoming smaller as they are closer to the connection position of the folding sleeve;

[0014] A flexible rod is passed through the clamping hole, and a sphere is connected to the bottom end of the flexible rod. The flexible rod is tilted in the clamping hole, and the closer the flexible rod is to the connection position of the two folding sleeves, the farther it is from the dust collection air pipe;

[0015] The sphere contacts the dust suction air pipe, and a spring is connected between the sphere and the fixing ring;

[0016] When the flexible rod moves, the flexible rod contacts the inner wall of the dust suction air pipe away from the clamping through hole, causing the flexible rod to bend toward the dust suction air pipe, so that the ball always keeps in contact with the dust suction air pipe and clamps the dust suction air pipe;

[0017] When the folding sleeve is folded, part of the dust suction air pipe in the folding sleeve extends out from the position where the two folding sleeves are separated. At this time, the movement of the dust suction air pipe drives the flexible rod to move to the position where the two folding sleeves are separated through the ball, compressing the spring. When the folding sleeves are connected, the spring resets, and the ball clamps the dust suction air pipe so that part of the dust suction air pipe is re-retracted into the folding sleeve.

[0018] In an optional embodiment, the maximum size of the clamping through hole is smaller than the diameter of the sphere. When the sphere contacts the fixing ring, it is blocked by the fixing ring, preventing part of the dust suction air pipe from continuing to extend from the position where the two folding sleeves are separated.

[0019] In an optional embodiment, a connecting rod is vertically connected to one end of the flexible rod near the connection position of the two folding sleeves, one end of the connecting rod is connected to the flexible rod, and the other end is provided with a handle;

[0020] When the handle extends out of the folding sleeve from the position where the two folding sleeves are separated, the handle contacts the portion of the dust suction air pipe that is in a bent state.

[0021] In an optional embodiment, a plurality of flow holes are opened on the inner wall of the fixing ring, and the length direction of the flow holes is parallel to the axis of the fixing ring;

[0022] The flow hole is arranged to be open on a portion of the side wall close to the dust suction air pipe;

[0023] The flow hole corresponds to the sphere.

[0024] In an optional embodiment, a hinge seat is fixedly provided on the outer wall of one folding sleeve, and a hinge block is provided on the outer wall of the other folding sleeve, and the hinge block is rotatably connected to the hinge seat;

[0025] The hinge seat and the hinge block are close to the connection position of the two folding sleeves;

[0026] The dust suction air pipe extends out of the portion of the folding sleeve that is in a bent state when the two folding sleeves are folded.

[0027] In an optional embodiment, a limiting protrusion is provided on the outer wall of the hinge block, and when the hinge seat contacts the limiting protrusion, the two folding sleeves are in a maximum folding state.

[0028] In an optional embodiment, the gas source is disposed in the housing, and one of the folding sleeves is connected to the housing;

[0029] The shell is provided with a handle, the handle is provided with a switch, and the switch is electrically connected to the gas source.

[0030] In a second aspect, the present disclosure further provides a clamping mechanism for the aforementioned handheld vacuum cleaner that is easy to store, comprising:

[0031] A fixing ring, wherein a plurality of clamping through holes are formed on the fixing ring, the clamping through holes are formed along the thickness direction of the fixing ring, and the clamping through holes are tapered;

[0032] A flexible rod is passed through the clamping through hole, a sphere is connected to the bottom end of the flexible rod, and the flexible rod is tiltedly arranged in the clamping through hole;

[0033] The maximum size of the clamping through hole is smaller than the diameter of the sphere;

[0034] A connecting rod is vertically connected to the flexible rod, one end of the connecting rod is connected to the flexible rod, and the other end is provided with a handle;

[0035] A plurality of flow holes are provided on the inner wall of the fixing ring, and the length direction of the flow holes is parallel to the axis of the fixing ring.

[0036] In a third aspect, the present disclosure further provides a method for storing the handheld vacuum cleaner that is easy to store, comprising:

[0037] When the two folding sleeves are folded, the clamping mechanism drives part of the dust suction air pipe to extend from the position where the two folding sleeves are separated, and this part of the dust suction air pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the clamped part of the dust suction air pipe into the folding sleeve so that there is no dust suction air pipe at the connection position of the two folding sleeves.

[0038] The beneficial effect of the present invention is that the handheld vacuum cleaner that is easy to store comprises: a pair of folding sleeves, a clamping mechanism is provided therein, and a dust suction air pipe, one end of which is connected to the air source through the folding sleeve, and the other end is connected to the dust suction mechanism through the folding sleeve, and the dust suction air pipe passes through the clamping mechanism; when the two folding sleeves are connected in the same straight line, the dust suction air pipe is bent and arranged in the folding sleeve; when the two folding sleeves are folded, the clamping mechanism drives part of the dust suction air pipe to extend from the position where the two folding sleeves are separated, and the part of the dust suction air pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the clamped dust suction air pipe part into the folding sleeve so that there is no dust suction air pipe at the connection position of the two folding sleeves, thereby achieving that when the two folding sleeves are connected, the dust suction air pipe part is automatically retracted into the inside of the folding sleeve, thereby avoiding the dust suction air pipe being clamped by the two connected folding sleeves.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration."

Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0057] The vacuum cleaner is folded by designing the middle connecting rod into a hinged structure, and then the main unit and the floor brush are placed on the ground at the same time by folding the connecting rod. When the vacuum cleaner is folded, the hose passing through the connecting rod will be stretched, and even folded at the hinge. The inventor found that when the vacuum cleaner is upright, the hose cannot recover quickly, and the hose will be clamped by the hinge point of the connecting rod, thereby damaging the hose. If the hose is further stressed after being folded, it will cause permanent creases or tears at the fold of the hose. Repeated folding or forced bending of the hose can easily cause deformation of the internal structure, material fatigue, and even breakage. Rubber protective agent (wax) should be applied regularly to the fold of the hose. However, the side of the hose folded near the hinge point of the connecting rod is in contact with the hinge point, making it difficult to apply the protective agent.

[0058] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0059] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0060] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0061] like Figure 1 As shown, at least one disclosed embodiment provides a handheld vacuum cleaner that is easy to store, comprising: a pair of folding sleeves 1, in which a clamping mechanism 4 is provided, a dust suction air pipe 2, one end of which is connected to the air source through the folding sleeve 1, and the other end is connected to the dust suction mechanism 3 through the folding sleeve 1, and the dust suction air pipe 2 passes through the clamping mechanism 4; when the two folding sleeves 1 are connected in the same straight line, the dust suction air pipe 2 is bent and arranged in the folding sleeve 1; when the two folding sleeves 1 are folded, the clamping mechanism 4 drives part of the dust suction air pipe 2 to extend from the position where the two folding sleeves 1 are separated, and the part of the dust suction air pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the clamped part of the dust suction air pipe 2 into the folding sleeve 1 again, so that there is no dust suction air pipe 2 at the connection position of the two folding sleeves 1, thereby achieving that when the two folding sleeves 1 are connected, the dust suction air pipe 2 is partially automatically retracted into the inside of the folding sleeve 1 to avoid the dust suction air pipe 2 being clamped by the two connected folding sleeves 1.

[0062] In this embodiment, the connection position of the two folding sleeves 1 is an annular surface that the two folding sleeves 1 contact when connected. When the two folding sleeves 1 are connected, there is no dust suction air pipe 2 between the two annular surfaces, which prevents the dust suction air pipe 2 from being clamped by the two connected folding sleeves 1.

[0063] In this embodiment, when the vacuum cleaner is stored, the two folding sleeves 1 are in a folded state. At this time, the dust collection mechanism 3 and the shell for installing the air source can contact the bottom surface at the same time, which is convenient for storing and placing the vacuum cleaner.

[0064] In this embodiment, the gas source is located in the housing 5, which is not shown in the figure.

[0065] like Figure 4 and Figure 5 As shown, in this embodiment, the dust suction air pipe 2 is a hose. When the folding sleeve 1 is in a folded state, the dust suction air pipe 2, which was originally in a bent state, will be stretched and bent; when the vacuum cleaner is working, the two folding sleeves 1 are in a connected state, and the two folding sleeves 1 are in the same straight line. At this time, the dust suction air pipe 2 is in a slightly bent state inside the folding sleeve 1, that is, the length of the dust suction air pipe 2 is longer than the total length of the two folding sleeves 1, so that when the vacuum cleaner is stored, the folding sleeve 1 is in a folded state, and the originally bent dust suction air pipe 2 is partially stretched, and part of the dust suction air pipe 2 extends from the separated position of the two folding sleeves 1, which facilitates the folding of the folding sleeve 1.

[0066] like Figure 2 As shown, in an optional embodiment, the clamping mechanism 4 includes: a fixing ring 41; the fixing ring 41 is arranged on the inner wall of the folding sleeve 1; a plurality of clamping through holes 42 are opened on the fixing ring 41, and the clamping through holes 42 are opened along the thickness direction of the fixing ring 41, and the clamping through holes 42 are conical, and the closer to the connection position of the folding sleeve 1, the smaller the area; a flexible rod 43 is passed through the clamping through hole 42, and the bottom end of the flexible rod 43 is connected to a ball 44, and the flexible rod 43 is tilted in the clamping through hole 42, and the closer the flexible rod 43 is to the connection position of the two folding sleeves 1, the farther it is from the dust suction air pipe 2; the ball 44 contacts the dust suction air pipe 2, and the ball 44 A spring 45 is connected to the fixing ring 41; when the flexible rod 43 moves, the flexible rod 43 contacts the inner wall of the clamping through hole 42 away from the dust suction air pipe 2, so that the flexible rod 43 bends toward the dust suction air pipe 2, so that the ball 44 always keeps in contact with the dust suction air pipe 2 and clamps the dust suction air pipe 2; when the folding sleeve 1 is folded, the part of the dust suction air pipe 2 in the folding sleeve 1 extends from the position where the two folding sleeves 1 are separated. At this time, the movement of the dust suction air pipe 2 drives the flexible rod 43 to move to the position where the two folding sleeves 1 are separated through the ball 44, compressing the spring 45. When the folding sleeve 1 is connected, the spring 45 is reset, and the ball 44 clamps the dust suction air pipe 2 so that the part of the dust suction air pipe 2 is re-retracted into the folding sleeve 1.

[0067] like Figure 5 As shown, in this embodiment, the clamping hole 42 can be in an inclined state, so that the flexible rod 43 will contact the clamping hole 42 away from the inner wall of the dust suction air pipe 2 when moving, causing the flexible rod 43 to bend, so that the ball 44 can better contact and clamp the outer wall of the dust suction air pipe 2.

[0068] In this embodiment, a clamping mechanism 4 is provided in each of the two folding sleeves 1 .

[0069] like Figure 6 and Figure 7 As shown, in this embodiment, the ball 44 contacts the dust suction air pipe 2 to clamp the dust suction air pipe 2. When the connected folding sleeve 1 begins to fold, the dust suction air pipe 2 is partially stretched and extends out of the folding sleeve 1 from the separation position of the two folding sleeves 1. At this time, the movement of the dust suction air pipe 2 drives the ball 44 to move, and the spring 45 is compressed. When the folding sleeve 1 is reconnected, the spring 45 resets, causing the ball 44 to clamp the dust suction air pipe 2 and retract into the folding sleeve 1. The dust suction air pipe 2 portion that was stretched out of the folding sleeve 1 when the folding sleeve 1 was folded is automatically retracted into the folding sleeve 1. At this time, there is no excess dust suction air pipe 2 at the connection position of the two folding sleeves 1, and the two folding sleeves 1 do not clamp the dust suction air pipe 2, thereby preventing the dust suction air pipe 2 from being clamped and damaged. The spring 45 can be mounted on the flexible rod 43 or not. The spring 45 always presses against the bottom surface of the fixing ring 41 and does not enter the clamping through hole 42.

[0070] like Figure 3 As shown, in an optional embodiment, the maximum size of the clamping hole 42 is smaller than the diameter of the sphere 44. When the sphere 44 contacts the fixing ring 41, it is blocked by the fixing ring 41, preventing part of the dust suction air pipe 2 from continuing to extend from the position where the two folding sleeves 1 are separated.

[0071] In this embodiment, if the folding sleeve 1 is folded too much, it will pull the dust suction air pipe 2 out of the air source and the dust suction mechanism 3 at both ends. The ball 44 contacts the fixed ring 41 to limit the position, thereby preventing the dust suction air pipe 2 from being in a tensioned state due to the folding of the folding sleeve 1, preventing the dust suction air pipe 2 from being separated from the air source and the dust suction mechanism 3, and preventing the dust suction air pipe 2 from being torn due to being tensioned.

[0072] In an optional embodiment, a connecting rod 46 is vertically connected to one end of the flexible rod 43 near the connection position of the two folding sleeves 1, one end of the connecting rod 46 is connected to the flexible rod 43, and the other end is provided with a handle 47; when the handle 47 extends out of the folding sleeve 1 from the position where the two folding sleeves 1 are separated, the handle 47 contacts the part of the vacuum air pipe 2 that is in a bent state.

[0073] In this embodiment, it is necessary to apply rubber protective agent to the dust suction air pipe 2. When the two folding sleeves 1 are in the folded state, the bent dust suction air pipe 2 will stick to the hinge seat 11 and the hinge block 12, making it difficult to apply the rubber protective agent. At this time, you can manually hold a handle 47 to pull the connecting rod 46 outward from the position where the folding sleeve 1 is separated to a certain length, that is, the sphere 44 will not contact the fixing ring 41. When the corresponding handle 47 drives the connecting rod 46 to move, the dust suction air pipe 2 will cause each sphere 44 to move synchronously to move all the connecting rods 46. The handle 47 contacts the bent part of the dust suction air pipe 2 from the bottom and pushes the bent part upward, so that the dust suction air pipe 2 is separated from the hinge seat 11 and the hinge block 12, which is convenient for applying the rubber protective agent.

[0074] In an optional embodiment, a plurality of flow holes 48 are provided on the inner wall of the fixing ring 41 , and the length direction of the flow holes 48 is parallel to the axis of the fixing ring 41 ; the flow holes 48 are opened near part of the side wall of the dust suction air pipe 2 ; the flow holes 48 correspond to the sphere 44 .

[0075] In this embodiment, after the rubber protective agent is applied, the rubber protective agent will flow along the outer wall of the dust suction air pipe 2, and after flowing through the flow hole 48, it will flow between the sphere 44 and the dust suction air pipe 2 at the corresponding position, thereby protecting the dust suction air pipe 2 at the corresponding position.

[0076] In an optional embodiment, a hinge seat 11 is fixedly provided on the outer wall of one folding sleeve 1, and a hinge block 12 is provided on the outer wall of the other folding sleeve 1, and the hinge block 12 is rotatably connected to the hinge seat 11; the hinge seat 11 and the hinge block 12 are close to the connection position of the two folding sleeves 1; the dust suction air pipe 2 extends out of the bent part of the folding sleeve 1 when the two folding sleeves 1 are folded.

[0077] In this embodiment, the two folding sleeves 1 can be folded together by the cooperation between the hinge seat 11 and the hinge block 12 .

[0078] In this embodiment, a snap-fit mechanism may be provided on the two folding sleeves 1 so as to fix the two folding sleeves 1 together when they are connected.

[0079] In an optional embodiment, a limiting protrusion 13 is provided on the outer wall of the hinge block 12 , and when the hinge seat 11 contacts the limiting protrusion 13 , the two folding sleeves 1 are in a maximum folding state.

[0080] In this embodiment, when the articulated seat 11 contacts the limiting protrusion 13, the two folding sleeves 1 are in the maximum folding state. At this time, the ball 44 contacts the fixing ring 41. If the limiting protrusion 13 is damaged, the cooperation between the ball 44 and the fixing ring 41 can prevent the folding degree of the folding sleeve 1 from increasing, thereby preventing the dust suction air pipe 2 from being pulled and causing damage to the dust suction air pipe 2 or the dust suction air pipe 2 from being separated from the air source and the dust suction mechanism 3.

[0081] In an optional embodiment, the gas source is arranged in the shell 5, and one of the folding sleeves 1 is connected to the shell 5; a handle 51 is provided on the shell 5, and a switch is provided on the handle 51, and the switch is electrically connected to the gas source.

[0082] At least one other disclosed embodiment also provides a clamping mechanism 4 used in the above-mentioned handheld vacuum cleaner that is easy to store, including: a fixing ring 41, a plurality of clamping through holes 42 are opened on the fixing ring 41, the clamping through holes 42 are opened along the thickness direction of the fixing ring 41, and the clamping through holes 42 are conical; a flexible rod 43 is passed through the clamping through hole 42, and the bottom end of the flexible rod 43 is connected to a sphere 44, and the flexible rod 43 is obliquely arranged in the clamping through hole 42; the maximum size of the clamping through hole 42 is smaller than the diameter of the sphere 44; a connecting rod 46 is vertically connected to the flexible rod 43, one end of the connecting rod 46 is connected to the flexible rod 43, and a handle 47 is provided at the other end; a plurality of flow holes 48 are opened on the inner wall of the fixing ring 41, and the length direction of the flow hole 48 is parallel to the axis of the fixing ring 41.

[0083] At least one other disclosed embodiment also provides a storage method for the above-mentioned handheld vacuum cleaner that is easy to store, including: when the two folding sleeves 1 are folded, the clamping mechanism 4 drives part of the dust suction air pipe 2 to extend from the position where the two folding sleeves 1 are separated, and the part of the dust suction air pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the clamped part of the dust suction air pipe 2 into the folding sleeve 1 so that there is no dust suction air pipe 2 at the connection position of the two folding sleeves 1.

[0084] To sum up, the handheld vacuum cleaner that is easy to store includes: a pair of folding sleeves 1, which are provided with a clamping mechanism 4, a dust suction air pipe 2, one end of which is connected to the air source through the folding sleeve 1, and the other end is connected to the dust suction mechanism 3 through the folding sleeve 1, and the dust suction air pipe 2 passes through the clamping mechanism 4; when the two folding sleeves 1 are connected in the same straight line, the dust suction air pipe 2 is bent and arranged in the folding sleeve 1; when the two folding sleeves 1 are folded, the clamping mechanism 4 drives part of the dust suction air pipe 2 to extend from the position where the two folding sleeves 1 are separated, and the part of the dust suction air pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the clamped part of the dust suction air pipe 2 into the folding sleeve 1 again, so that there is no dust suction air pipe 2 at the connection position of the two folding sleeves 1, thereby achieving that when the two folding sleeves 1 are connected, the dust suction air pipe 2 is partially automatically retracted into the inside of the folding sleeve 1, avoiding the dust suction air pipe 2 being clamped by the two connected folding sleeves 1.

When the folding sleeves (1) are connected, the clamping mechanism (4) retracts the clamped portion of the dust suction air pipe (2) back into the folding sleeves (1), so that the dust suction air pipe (2) does not exist at the connection position of the two folding sleeves (1); The clamping mechanism (4) comprises: a fixing ring (41); The fixing ring (41) is arranged on the inner wall of the folding sleeve (1); The fixing ring (41) is provided with a plurality of clamping through holes (42), the clamping through holes (42) being provided along the thickness direction of the fixing ring (41), and the clamping through holes (42) being tapered, with the area becoming smaller as they are closer to the connection position of the folding sleeve (1); A flexible rod (43) is passed through the clamping through hole (42), and a sphere (44) is connected to the bottom end of the flexible rod (43). The flexible rod (43) is tilted in the clamping through hole (42), and the closer the flexible rod (43) is to the connection position of the two folding sleeves (1), the farther it is from the dust collection air pipe (2); The sphere (44) contacts the dust suction air pipe (2), and a spring (45) is connected between the sphere (44) and the fixing ring (41); When the flexible rod (43) moves, the flexible rod (43) contacts the inner wall of the clamping through hole (42) away from the dust suction air pipe (2), so that the flexible rod (43) bends toward the dust suction air pipe (2), so that the ball (44) always keeps in contact with the dust suction air pipe (2), clamping the dust suction air pipe (2); When the folding sleeve (1) is folded, a portion of the dust suction air pipe (2) in the folding sleeve (1) extends from the position where the two folding sleeves (1) are separated. At this time, the movement of the dust suction air pipe (2) drives the flexible rod (43) to move toward the position where the two folding sleeves (1) are separated through the sphere (44), compressing the spring (45). When the folding sleeves (1) are connected, the spring (45) is reset, and the sphere (44) clamps the dust suction air pipe (2) so that the portion of the dust suction air pipe (2) is retracted into the folding sleeve (1). The maximum size of the clamping through hole (42) is smaller than the diameter of the sphere (44), and when the sphere (44) contacts the fixing ring (41), it is blocked by the fixing ring (41), thereby preventing part of the dust suction air pipe (2) from continuing to extend from the position where the two folding sleeves (1) are separated; A connecting rod (46) is vertically connected to one end of the flexible rod (43) near the connection position of the two folding sleeves (1); one end of the connecting rod (46) is connected to the flexible rod (43), and the other end is provided with a handle (47); When the handle (47) extends out of the folding sleeve (1) from the position where the two folding sleeves (1) are separated, the handle (47) contacts the portion of the dust suction air pipe (2) that is in a bent state.
