Description

Technical Field

[0001] The present invention belongs to the technical field of general vacuum cleaners, specifically relates to the washing or cleaning of households, and particularly relates to a handheld vacuum cleaner, a clamping mechanism and a storage method that are convenient for storage. Background Art

[0002] For the storage of the vacuum cleaner, the middle connecting rod is designed as a hinged structure, and the main body and the floor brush are simultaneously landed through the folding of the connecting rod. In the folded state of the vacuum cleaner, the hose passing through the inside of the connecting rod will be stretched, and even the hose will be folded at the hinge point. In this way, when the vacuum cleaner is upright, the hose cannot quickly return, so the hose will be clamped by the hinge point of the connecting rod or the connecting position of the connecting rod, thus 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 connecting position of the connecting rod during connection, it is necessary to design a handheld vacuum cleaner, a clamping mechanism and a storage method that are convenient for storage.

[0004] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as 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 convenient for storage.

[0006] In a first aspect, the embodiments of the present disclosure provide a handheld vacuum cleaner that is convenient for storage, including: A pair of folding sleeves, inside which a clamping mechanism is provided, A suction air pipe, one end of which is connected to a gas source through the folding sleeve, and the other end is connected to a suction mechanism through the folding sleeve, and the suction air pipe passes through the clamping mechanism; When the two folding sleeves are connected in a straight line, the suction air pipe is bent and arranged inside the folding sleeve; When the two folding sleeves are folded, the clamping mechanism drives a part of the suction air pipe to extend from the position where the two folding sleeves are separated, and this part of the suction air pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the part of the suction air pipe it clamps back into the folding sleeve, so that there is no suction air pipe at the connection position of the two folding sleeves.

[0007] In an optional embodiment, the clamping mechanism includes: a fixed ring; The fixed ring is arranged on the inner wall of the folding sleeve; A number of clamping through holes are opened on the fixed ring, the clamping through holes are opened along the thickness direction of the fixed ring, and the clamping through holes are conical, and the area is smaller closer to the connection position of the folding sleeve; A flexible rod is inserted through the clamping through-hole. A sphere is connected to the bottom end of the flexible rod. The flexible rod is inclined in the clamping through-hole, and the closer the flexible rod is to the connection position of the two folding sleeves, the farther it is from the dust suction pipe. The sphere contacts the dust suction pipe, and a spring is connected between the sphere and the fixed ring. When the flexible rod moves, the flexible rod contacts the inner wall of the clamping through-hole far from the dust suction pipe, causing the flexible rod to bend towards the dust suction pipe, so that the sphere always remains in contact with the dust suction pipe and clamps the dust suction pipe. When the folding sleeves are folded, the part of the dust suction pipe in the folding sleeves extends from the position where the two folding sleeves are separated. At this time, the movement of the dust suction pipe drives the flexible rod to move towards the position where the two folding sleeves are separated through the sphere, compressing the spring. When the folding sleeves are connected, the spring resets, and the sphere clamps the dust suction pipe so that the part of the dust suction pipe retracts into the folding sleeves again.

[0008] 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 fixed ring, it is blocked by the fixed ring to prevent the part of the dust suction pipe from continuing to extend from the position where the two folding sleeves are separated.

[0009] In an optional embodiment, a connecting rod is vertically connected to one end of the flexible rod close to 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. When the handle extends out of the folding sleeve from the position where the two folding sleeves are separated, the handle contacts the bent part of the dust suction pipe.

[0010] In an optional embodiment, a plurality of flow holes are formed in the inner wall of the fixed ring, and the length direction of the flow holes is parallel to the axis of the fixed ring. The side wall of the part of the flow hole close to the dust suction pipe is open. The flow holes correspond to the spheres.

[0011] In an optional embodiment, a hinge seat is fixedly arranged on the outer wall of one folding sleeve, and a hinge block is arranged on the outer wall of the other folding sleeve. The hinge block is rotatably connected to the hinge seat. The hinge seat and the hinge block are close to the connection position of the two folding sleeves. The part of the dust suction pipe that extends out of the folding sleeve and is bent when the two folding sleeves are folded.

[0012] In an optional embodiment, a limiting protrusion is arranged on the outer wall of the hinge block. When the hinge seat contacts the limiting protrusion, the two folding sleeves are in the maximum folding state.

[0013] In an alternative embodiment, the air source is disposed in the housing, and one of the folding sleeves is connected to the housing; A grip is provided on the housing, a switch is provided on the grip, and the switch is electrically connected to the air source.

[0014] In a second aspect, an embodiment of the present disclosure further provides a clamping mechanism used in the above-mentioned portable vacuum cleaner that is convenient for storage, including: A fixing ring is provided with a plurality of clamping through holes, the clamping through holes are opened along the thickness direction of the fixing ring, and the clamping through holes are conical; 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 inclined in the clamping through hole; The maximum dimension of the clamping through hole is smaller than the diameter of the sphere; 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; 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.

[0015] In a third aspect, an embodiment of the present disclosure further provides a storage method for using the above-mentioned portable vacuum cleaner that is convenient for storage, including: When the two folding sleeves are folded, the clamping mechanism drives a part of the suction pipe to extend from the position where the two folding sleeves are separated. This part of the suction pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the clamped part of the suction pipe back into the folding sleeve so that there is no suction pipe at the connection position of the two folding sleeves.

[0016] The beneficial effects of the present invention are as follows: The portable vacuum cleaner that is convenient for storage includes: a pair of folding sleeves, a clamping mechanism is disposed therein, a suction pipe, one end of which is connected to the air source through the folding sleeve, and the other end is connected to the suction mechanism through the folding sleeve, and the suction pipe passes through the clamping mechanism; when the two folding sleeves are connected in a straight line, the suction pipe is bent and disposed in the folding sleeve; when the two folding sleeves are folded, the clamping mechanism drives a part of the suction pipe to extend from the position where the two folding sleeves are separated. This part of the suction pipe is in a bent state. When the folding sleeves are connected, the clamping mechanism retracts the clamped part of the suction pipe back into the folding sleeve so that there is no suction pipe at the connection position of the two folding sleeves, thereby realizing that when the two folding sleeves are connected, the suction pipe part automatically retracts into the folding sleeve to avoid the suction pipe being clamped by the two connected folding sleeves.

Detailed Description of the Embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

Therefore, a specific feature, structure, or characteristic can 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, terms such as "example", "exemplary", etc. are used "for the purpose of serving as an example, instance, or illustration.

On the contrary, the use of terms such as "example", "exemplary", etc. is intended to present concepts in a specific manner.

[0024] The storage of the vacuum cleaner is achieved by designing the middle connecting rod into a hinged structure, and then realizing the simultaneous grounding of the main body and the floor brush through the folding of the connecting rod. In the folded state of the vacuum cleaner, the hose passing through the inside of the connecting rod will be stretched, and even the hose will be folded at the hinge. The inventor found that when the vacuum cleaner is upright, the hose cannot quickly return, so that the hose will be clamped by the hinge point of the connecting rod, thus damaging the hose. If the hose is further stressed after folding, it will cause permanent creases or tears at the folding part of the hose. Repeated folding or forced bending of the hose easily causes deformation of the internal structure, material fatigue, and even fracture. Rubber protectant (wax) should be regularly applied to the folding part of the hose. However, one side of the hose folding close to the hinge point of the connecting rod is in contact with the hinge point, making it difficult to apply the protectant.

[0025] Regarding the defects existing in the above solutions, they are all the results obtained by the inventor through practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed in the present disclosure by the present disclosure for the above problems should all be the contributions made by the inventor to the present disclosure during the process of the present disclosure.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0027] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0028] As Figure 1 shown, at least one disclosed embodiment provides a handheld vacuum cleaner that is convenient for storage, including: a pair of folding sleeves 1, inside which a clamping mechanism 4 is provided; a suction pipe 2, one end of which is connected to a gas source through the folding sleeve 1, and the other end is connected to a suction mechanism 3 through the folding sleeve 1, and the suction pipe 2 passes through the clamping mechanism 4; when the two folding sleeves 1 are connected in a straight line, the suction pipe 2 is bent and arranged inside the folding sleeve 1; when the two folding sleeves 1 are folded, the clamping mechanism 4 drives a part of the suction pipe 2 to extend from the position where the two folding sleeves 1 are separated, and this part of the suction pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the part of the suction pipe 2 it holds back into the folding sleeve 1 again, so that there is no suction pipe 2 at the connection position of the two folding sleeves 1, thereby realizing that when the two folding sleeves 1 are connected, the part of the suction pipe 2 automatically retracts into the folding sleeve 1, avoiding the suction pipe 2 being clamped by the two connected folding sleeves 1.

[0029] In this embodiment, the connection position of the two folding sleeves 1 is the annular surface where the two folding sleeves 1 contact when connected. When the two folding sleeves 1 are connected, there is no suction pipe 2 between the two annular surfaces, avoiding the suction pipe 2 being clamped by the two connected folding sleeves 1.

[0030] In this embodiment, when storing the vacuum cleaner, the two folding sleeves 1 are in a folded state. At this time, the suction mechanism 3 and the housing for installing the gas source can both contact the bottom surface, which is convenient for storing and placing the vacuum cleaner.

[0031] In this embodiment, the gas source is located in the housing 5, which is not shown in the figure.

[0032] As Figure 4 and Figure 5 shown, in this embodiment, the suction pipe 2 is a flexible pipe. When the folding sleeve 1 is in a folded state, the originally bent suction pipe 2 will be stretched and bent; when the vacuum cleaner is working, the two folding sleeves 1 are in a connected state and in a straight line. At this time, the suction pipe 2 is in a slightly bent state inside the folding sleeve 1, that is, the length of the suction pipe 2 is longer than the total length of the two folding sleeves 1. When storing and placing the vacuum cleaner, the folding sleeve 1 is in a folded state, and the stretched part of the originally bent suction pipe 2 extends from the position where the two folding sleeves 1 are separated, which is convenient for folding the folding sleeve 1.

[0033] As Figure 2As shown, in an alternative embodiment, the clamping mechanism 4 includes: a fixing ring 41; the fixing ring 41 is disposed on the inner wall of the folding sleeve 1; a plurality of clamping through holes 42 are formed in the fixing ring 41, the clamping through holes 42 are formed along the thickness direction of the fixing ring 41, the clamping through holes 42 are conical, and the area is smaller closer to the connection position of the folding sleeve 1; a flexible rod 43 is disposed in the clamping through hole 42, a sphere 44 is connected to the bottom end of the flexible rod 43, the flexible rod 43 is inclined in the clamping through hole 42, and the flexible rod 43 is farther away from the dust suction pipe 2 closer to the connection position of the two folding sleeves 1; the sphere 44 contacts the dust suction 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 pipe 2, so that the flexible rod 43 is bent toward the dust suction pipe 2, so that the sphere 44 always keeps contacting the dust suction pipe 2 and clamps the dust suction pipe 2; when the folding sleeve 1 is folded, a part of the dust suction 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 pipe 2 drives the flexible rod 43 to move toward the position where the two folding sleeves 1 are separated through the sphere 44, compresses the spring 45, and when the folding sleeve 1 is connected, the spring 45 resets, and the sphere 44 clamps the dust suction pipe 2 so that a part of the dust suction pipe 2 retracts into the folding sleeve 1 again.

[0034] As Figure 5 shown, in this embodiment, the clamping through hole 42 can be in an inclined state, so that when the flexible rod 43 moves, it will contact the inner wall of the clamping through hole 42 away from the dust suction pipe 2, causing the flexible rod 43 to bend, so that the sphere 44 can better contact and clamp the outer wall of the dust suction pipe 2.

[0035] In this embodiment, the clamping mechanism 4 is disposed in both of the two folding sleeves 1.

[0036] As Figure 6 and Figure 7 shown, in this embodiment, the sphere 44 contacts the dust suction pipe 2 to clamp the dust suction pipe 2. When the connected folding sleeve 1 starts to fold, a part of the dust suction pipe 2 is stretched and extends out of the folding sleeve 1 from the position where the two folding sleeves 1 are separated. At this time, the movement of the dust suction pipe 2 drives the sphere 44 to move, and the spring 45 is compressed. When the folding sleeve 1 is reconnected, the spring 45 resets so that the sphere 44 clamps the dust suction pipe 2 and contracts it toward the inside of the folding sleeve 1, so that the part of the dust suction pipe 2 that is stretched and extended out of the folding sleeve 1 when the folding sleeve 1 is folded is automatically retracted into the folding sleeve 1 again. At this time, there is no redundant part of the dust suction pipe 2 at the connection position of the two folding sleeves 1, and the two folding sleeves 1 do not clamp the dust suction pipe 2, avoiding damage to the dust suction pipe 2 caused by clamping. The spring 45 can be sleeved on the flexible rod 43 or not, and the spring 45 always abuts against the bottom surface of the fixing ring 41, and the spring 45 does not enter the clamping through hole 42.

[0037] As Figure 3 shown, in an alternative embodiment, the maximum size of the clamping through 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 a part of the dust suction air pipe 2 from continuing to extend from the position where the two folding sleeves 1 are separated.

[0038] In this embodiment, if the folding degree of the folding sleeve 1 is too large, it will pull the dust suction air pipe 2 away from the air source and the dust suction mechanism 3 at both ends. By the limit of the sphere 44 contacting the fixing ring 41, it is avoided that the dust suction air pipe 2 is in a tensioned state due to the folding of the folding sleeve 1, preventing the dust suction air pipe 2 from detaching from the air source and the dust suction mechanism 3, and avoiding tearing and other situations of the dust suction air pipe 2 due to being tightened.

[0039] In an alternative embodiment, a connecting rod 46 is vertically connected to one end of the flexible rod 43 near the connecting 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 bent part of the dust suction air pipe 2.

[0040] In this embodiment, when it is necessary to apply rubber protective agent to the dust suction air pipe 2, when the two folding sleeves 1 are in a 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, one can manually hold a handle 47 and pull the connecting rod 46 outwards by a certain length from the position where the two folding sleeves 1 are separated, that is, the sphere 44 will not contact the fixing ring 41. Correspondingly, when the handle 47 drives the connecting rod 46 to move, the dust suction air pipe 2 will cause all the spheres 44 to move synchronously so that all the connecting rods 46 move. The handle 47 contacts the bent part of the dust suction air pipe 2 from below and pushes the bent part upwards, causing the dust suction air pipe 2 to disengage from the hinge seat 11 and the hinge block 12, facilitating the application of the rubber protective agent.

[0041] In an alternative embodiment, a plurality of flow holes 48 are formed in the inner wall of the fixing ring 41. The length direction of the flow holes 48 is parallel to the axis of the fixing ring 41; the side wall of the part of the flow hole 48 close to the dust suction air pipe 2 is open; the flow holes 48 correspond to the spheres 44.

[0042] 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 holes 48, it will flow to between the sphere 44 and the corresponding position of the dust suction air pipe 2 to protect the dust suction air pipe 2 at the corresponding position.

[0043] In an alternative embodiment, a hinge seat 11 is fixedly arranged on the outer wall of a folding sleeve 1, and a hinge block 12 is arranged on the outer wall of the other folding sleeve 1. 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 folding sleeve 1 in a bent state when the two folding sleeves 1 are folded.

[0044] In this embodiment, the cooperation of the hinge seat 11 and the hinge block 12 can realize the folding of the two folding sleeves 1.

[0045] In this embodiment, a clamping mechanism can be arranged on the two folding sleeves 1 to fix the two folding sleeves 1 through the clamping mechanism when they are connected.

[0046] In an alternative embodiment, a limiting protrusion 13 is arranged on the outer wall of the hinge block 12. When the hinge seat 11 contacts the limiting protrusion 13, the two folding sleeves 1 are in the maximum folding state.

[0047] In this embodiment, when the hinge seat 11 contacts the limiting protrusion 13, the two folding sleeves 1 are in the maximum folding state. At this time, the sphere 44 contacts the fixed ring 41. If the limiting protrusion 13 is damaged, the cooperation between the sphere 44 and the fixed ring 41 can be used to prevent the folding degree of the folding sleeve 1 from increasing, and prevent the dust suction air pipe 2 from being pulled, resulting in damage to the dust suction air pipe 2 or the disconnection of the dust suction air pipe 2 from the air source and the dust suction mechanism 3.

[0048] In an alternative embodiment, the air source is arranged in the housing 5, and one of the folding sleeves 1 is connected to the housing 5. A handle 51 is arranged on the housing 5, and a switch is arranged on the handle 51. The switch is electrically connected to the air source.

[0049] At least one other disclosed embodiment also provides a clamping mechanism 4 used in the above-mentioned handheld vacuum cleaner that is convenient for storage, including: a fixed ring 41, a plurality of clamping through holes 42 are opened on the fixed ring 41. The clamping through holes 42 are opened along the thickness direction of the fixed ring 41, and the clamping through holes 42 are conical. A flexible rod 43 is inserted through the clamping through hole 42. The bottom end of the flexible rod 43 is connected with a sphere 44. 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 the other end is provided with a handle 47. A plurality of flow holes 48 are opened on the inner wall of the fixed ring 41. The length direction of the flow holes 48 is parallel to the axis of the fixed ring 41.

[0050] At least one other publicly disclosed embodiment also provides a method for storing the above-mentioned portable vacuum cleaner that is convenient for storage, including: when the two folding sleeves 1 are folded, the clamping mechanism 4 drives a part of the dust suction pipe 2 to extend from the position where the two folding sleeves 1 are separated. This part of the dust suction pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the part of the dust suction pipe 2 it holds back into the folding sleeves 1 so that there is no dust suction pipe 2 at the connection position of the two folding sleeves 1.

[0051] In summary, the portable vacuum cleaner that is convenient for storage includes: a pair of folding sleeves 1, inside which there is a clamping mechanism 4, a dust suction pipe 2, one end of which is connected to a gas source through the folding sleeve 1, and the other end is connected to a dust suction mechanism 3 through the folding sleeve 1, and the dust suction pipe 2 passes through the clamping mechanism 4; when the two folding sleeves 1 are connected in a straight line, the dust suction pipe 2 is bent and arranged inside the folding sleeves 1; when the two folding sleeves 1 are folded, the clamping mechanism 4 drives a part of the dust suction pipe 2 to extend from the position where the two folding sleeves 1 are separated. This part of the dust suction pipe 2 is in a bent state. When the folding sleeves 1 are connected, the clamping mechanism 4 retracts the part of the dust suction pipe 2 it holds back into the folding sleeves 1 so that there is no dust suction pipe 2 at the connection position of the two folding sleeves 1, thereby realizing that when the two folding sleeves 1 are connected, the part of the dust suction pipe 2 automatically retracts into the folding sleeves 1, avoiding the dust suction pipe 2 being clamped by the two connected folding sleeves 1.
