DETAILED DESCRIPTION

[0048] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0049] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0050] The present invention provides a handheld vacuum cleaner, which can be referred to Figure 1 ,2 As shown, it includes a handheld part and a dust cylinder 10, the handheld part supports the dust cylinder 10, the dust cylinder 10 is provided with an openable cover 16, the handheld part is provided with an operating part 5 and a transmission structure, the operating part 5 opens the cover 16 through the transmission structure, the handheld part includes a plug end 13 connected to an accessory, a trigger rod 14 is provided between the plug end 13 and the operating part 5, when the accessory is connected to the plug end 13, the accessory drives the trigger rod 14 to move in a first direction to lock the operating part 5, when the accessory is removed from the plug end 13, the trigger rod 14 moves in a second direction opposite to the first direction to unlock the operating part 5. The accessories are, for example, a flat straw, an extension tube, a bristle straw, and the like.

[0051] The handheld vacuum cleaner can operate the operating part 5 to realize a one-key dust emptying function or a one-key garbage emptying function.

[0052] The transmission structure is any structure that can transmit the movement of the trigger rod 14 and open the cover 16. It is applicable to the present disclosure. Therefore, there are many structures that cannot be listed one by one. The following is a transmission structure for exemplary description. The transmission structure of this example indirectly releases the limit of the cover 16 by swinging the dust cylinder 10, thereby achieving the purpose of opening the cover 16. The specific structure can be referred to the following description.

[0053] In some embodiments, the plug end 13 includes a plug hole 40 and an annular end surface 41 located in the circumference of the plug hole 40. The annular end surface 41 is provided with a through hole for the trigger rod 14 to extend out. When the operating part 5 is unlocked, the front end of the trigger rod 14 extends out of the through hole. When the accessory is connected to the plug end 13, the end surface of the accessory pushes the trigger rod 14 back to generate a first direction movement. Figure 1 , 11 As shown, Figure 1 The middle is the extended state. Fig.11 After such design, it is avoided to make a big change to the attachment, so that the present invention is compatible with the existing attachment, and the structure of the attachment itself does not need to be modified, which is conducive to reducing costs.

[0054] In some embodiments, Figure 2 As shown, the trigger rod 14 is connected to the first elastic member 17. When the plug end 13 is not connected to an accessory, the first elastic member 17 causes the front end of the trigger rod 14 to extend outside the plug end 13, and the operating part 5 is in an unlocked state. When the plug end 13 is connected to an accessory, the accessory pushes the trigger rod 14 back through the front end of the trigger rod 14, and at the same time, the first elastic member 17 is compressed, and the trigger rod 14 pushes back to lock the operating part 5. With such a structure, when removing an accessory, the trigger rod 14 can be automatically popped outward by the first elastic member 17, ready for the next connection of an accessory.

[0055] Furthermore, in order to limit the front end of the trigger rod 14 extending outside the plug-in end 13 and prevent it from getting loose, the trigger rod 14 is further provided with a limiting ring 18, which plays an axial positioning role.

[0056] In some embodiments, Figure 4 , 7 As shown in Figures 1 and 16, a slider 7 is provided between the trigger rod 14 and the operating part 5. The trigger rod 14 is connected to the slider 7 to drive the slider 7 to move. The operating part 5 is provided with a first lever 33 that cooperates with the slider 7. One end of the first lever 33 cooperates with the slider 7, and the other end cooperates with the stop portion 43. When the trigger rod 14 moves along the first direction, the trigger rod 14 drives the slider 7 to cooperate with one end of the first lever 33 to make the first lever 33 swing. The first lever 33 swings so that the other end thereof cooperates with the stop portion 43. The stop portion 43 limits the operating part 5 from moving backward through the first lever 33. When the trigger rod 14 moves along the second direction, the trigger rod 14 drives the slider 7 to move in the opposite direction so that the first lever 33 swings in the opposite direction. The first lever 33 swings in the opposite direction so that the other end thereof is released from the stop portion 43, such as being retracted into the following cooperation groove 44. The stop portion 43 releases the restriction on the movement of the operating part 5, and the operating part 5 can move backward. With this design, the trigger rod 14 can achieve the purpose of locking / unlocking with a smaller movement stroke, which is of great significance to the vacuum cleaner field described in the present disclosure, because the trigger rod 14 only needs to be extended a little bit, and is not easy to get caught on other objects or be damaged.

[0057] like Fig.16 As shown, a fourth matching surface 52 is provided on the lower side of the slider 7 , and the fourth matching surface 52 is slidably matched with the upper side surface of the first lever 33 .

[0058] In this disclosure, Figure 4 As shown, the first lever 33 is preferably a lever with one end of the first lever 33 as a rotation fulcrum, and the other ends of the slider 7 and the first lever 33 are located on the same side relative to the rotation fulcrum, and are both located on the rear side as shown in the figure. In this way, since the distance from the other end of the first lever 33 to the rotation fulcrum is much larger than the distance from the slider 7 to the rotation fulcrum, a smaller movement of the slider 7 will cause the other end of the first lever 33 to swing to a larger extent. In addition, according to the above design, the overall length of the first lever 33 can also be shorter, which is beneficial to reducing the axial length dimension of the structure.

[0059] In some embodiments, Figure 4 , 7As shown in Figures 9 and 10, the operating part 5 is provided with a vertical receiving groove, in which the first lever 33 can be connected to swing up and down, and the upper side of the receiving groove is provided with an opening 42, and the matching end of the slider 7 matches with the first lever 33 from the upper side of the receiving groove. Of course, the lower side of the receiving groove can also be provided with an opening 42, and the matching end of the slider 7 matches with the first lever 33 from the lower side of the receiving groove, as shown in the figure. This design is conducive to reducing the size and effectively improving the compactness of the structure. The operating part 5 and the first lever 33 can be connected to form an assembly first, which is convenient for production and assembly. The guiding effect of the receiving groove can make the up and down movement of the first lever 33 stable and not easy to produce abnormal noise. In addition, the first lever 33 is protected by the receiving groove and will not interfere with other parts to damage the first lever 33, which is conducive to improving reliability.

[0060] The aforementioned improvements are of great significance to handheld vacuum cleaners, because the structure of a handheld vacuum cleaner itself needs to be lightweight, and setting up an anti-misoperation structure will inevitably lead to additional structure. After adopting the aforementioned improvements, the anti-misoperation structure can better meet the requirements of the handheld vacuum cleaner for structural compactness and size.

[0061] In some embodiments, Fig.10 , 11 As shown, the rear end of the operating portion 5 is provided with an opening 42 connected to the vertical receiving groove, and the other end of the first lever 33 can be exposed through the opening 42 when the first lever 33 swings, and the hand-held portion is provided with a blocking portion corresponding to the side of the opening 42, and the blocking portion serves as a stop portion 43. After such a design, not only the structure is simplified and the problem of setting the stop portion 43 is solved, but also the swing amplitude of the first lever 33 can be smaller, which is conducive to reducing the degree of exposure of the trigger rod 14.

[0062] In some embodiments, Fig.11 , 12 As shown, a matching groove 44 is provided on the front side of the trigger 3 of the hand-held part, which is slidably connected to the operating part 5 in the front-to-back direction, and the rear end of the matching groove 44 serves as a stopper 43. This not only solves the installation problem of the operating part 5, but also makes the location very convenient for the user to operate the operating part 5. In addition, the rear end of the matching groove 44 serves as the stopper 43, thus solving the problem of setting the stopper 43 at the same time. In short, after such a design, it is not only convenient to operate, but also has a great effect on improving the compactness of the structure.

[0063] In some embodiments, Figure 1 As shown, the operating portion 5 is disposed on the front side of the trigger 3 of the handheld portion, and the space between the operating portion 5 and the trigger 3 accommodates the operating finger of the user.

[0064] For more comfortable operation, the operating portion 5 includes a pull ring 15 , which is used for the user's operating finger to pull the operating portion 5 .

[0065] In some embodiments, Figure 4 As shown, the second elastic member 19 is also included, and the second elastic member 19 is connected to the first lever 33. When the trigger rod 14 drives the slider 7 to move away from one end of the first lever 33, the second elastic member 19 provides a force for the first lever 33 to swing in the opposite direction. This design is conducive to ensuring the effective reset of the first lever 33, and is not prone to malfunctions during frequent use of the product.

[0066] In some embodiments, Figure 4 As shown, it also includes an operation button 6, which is connected to the slider 7. The operation button 6 is used for the user to manually drive the slider 7 to move to achieve locking / unlocking of the operating part 5. After this arrangement, the user can also lock it without connecting the accessories.

[0067] Further, such as Figure 4 , 17 As shown, it also includes a first locking portion 8, which is connected to the operating button 6 and can move together. The hand-held portion is provided with a fixed second locking portion 9, and the first locking portion 8 and the second locking portion 9 can cooperate with each other to lock / unlock the operating button 6. When the accessory is connected to the plug-in end 13, the trigger rod 14 moves along the first direction to drive the slider 7, the operating button 6 and the first locking portion 8 to move together and finally make the first locking portion 8 and the second locking portion 9 cooperate to lock the operating button 6, and the operating portion 5 is locked. When the accessory is removed from the plug-in end 13, the slider 7 will not be reset in the reverse direction because the operating button 6 is locked, and the operating portion 5 remains locked. When the user manually releases the cooperation between the first locking portion 8 and the second locking portion 9, the operating button 6 and the slider 7 are reset in the reverse direction, and the operating portion 5 is unlocked. In this way, on the one hand, when there is no accessory connected and there is no need to empty the garbage, it can be actively locked to avoid opening due to accidental operation. On the other hand, when the accessory is removed from the plug-in end 13, the slider 7 will not be reset in the opposite direction because the operating button 6 is locked, and the operating part 5 remains locked to avoid the situation in which the user holds the handheld vacuum cleaner in one hand and the accessory in the other hand during the removal of the accessory. In this case, if the operating part 5 is accidentally touched, it will cause it to open. The above improvement effectively avoids this situation.

[0068] like Fig.17 As shown, the first locking portion 8 includes a first barb 25, and the second locking portion 9 includes a second barb 26. The first barb 25 and the second barb 26 can cooperate with each other to lock / unlock the operation button 6. The user pushes the first barb 25 or the second barb 26 to release the cooperation between the two to release the lock. In this example, the user pushes the first barb 25 to compress the sixth elastic member 31 to release the cooperation between the first barb 25 and the second barb 26. Fig.17The directions in the figure represent two movement directions. When the operating button 6 is moved to the right as shown in the figure, the first barb 25 and the second barb 26 cooperate with each other to lock. When the first locking portion 8 is pressed, the button 6 is unlocked and moves in the opposite direction together with the slider 7.

[0069] In some embodiments, reference Figure 1 , 2 As shown in Figures 6, 8, 11 and 12, the hand-held part includes a handle 2 and an axial support part 4 arranged on the upper side of the handle 2, and the lower end of the handle 2 is connected to the battery part 1 to achieve the purpose of wireless operation. The front end of the axial support part 4 serves as the plug-in end 13, and the dust bin 10 set on the upper side of the axial support part 4 can be swung open. It also includes a third locking part 23 and a fourth locking part 24. The third locking part 23 swings together with the dust bin 10. When the dust bin 10 is reset, the third locking part 23 is reset and locked with the fourth locking part 24. The fourth locking part 24 is connected to the operating part 5. The operating part 5 is used to drive the fourth locking part 24 to move to release the lock between the third locking part 23 and the fourth locking part 24, so that the dust bin 10 can be swung open. After the dust bin 10 is swung open, the cover 16 can be opened and the dust bin 10 can be emptied. As shown in Figure 1 , 2 As shown, the upper side depression of the axial support part 4 cooperates with the dust cylinder 10 up and down, and the front end of the upper side depression is provided with a limiting surface. Before the dust cylinder 10 is swung open, the cover 16 is limited by the limiting surface and cannot be opened forward. When the dust cylinder 10 swings upward, the cover 16 is free from the limitation of the limiting surface and can be opened. In order to realize automatic opening, a torsion spring is provided at the axis of the cover 16, so that the elastic force of the torsion spring is used to make the cover 16 automatically open after being free from the limitation of the limiting surface.

[0070] Of course, the lower side of the axial support portion 4 may be swung open to set the dust cylinder 10, thereby releasing the limit on the cover 16.

[0071] In the accompanying drawings, there is a coaxially arranged dust cylinder bracket 11, which is used to detachably connect the dust cylinder 10. The dust cylinder bracket 11 is also equipped with a device for generating suction force such as an electric fan. The peripheral wall of the dust cylinder bracket 11 is also provided with an exhaust hole 12, so that the airflow extracted by the electric fan is discharged to form a negative pressure suction force. The dust cylinder bracket 11 and the dust cylinder 10 together constitute a main unit in a cylindrical shape as a whole. The main unit as a whole can swing relative to the rear end of the axial support part 4 through a rotating shaft 30 arranged between the rear end of the dust cylinder bracket 11 and the rear end of the axial support part 4. The flow channel is arranged in the axial support part 4, and the flow channel extends axially from the plug-in end 13 along the axial support part 4 and reaches the lower side of the main unit. The dust cylinder 10 is provided with a docking port, which docks with the outlet of the flow channel, thereby realizing an air channel connected in sequence from the plug-in end 13, the flow channel, the dust cylinder 10, the electric fan, and the exhaust hole 12. When the dust cylinder 10 is swung open, the flow channel outlet and the docking port are separated up and down. When the dust cylinder 10 is swung back and reset, the flow channel outlet and the docking port are docked again.

[0072] In some embodiments, Figure 2 , 3 As shown in , 5, 7, 8, 13, 14, 15, 18, and 19, the axial support portion 4 is provided with a movable portion 22 which can reciprocate along the axial direction, and the third locking portion 23 is provided with a hook, and the movable portion 22 and the hook can cooperate with each other up and down to limit the hook, and the fourth locking portion 24 is a second lever rotatably connected to the axial support portion 4, and the lower end of the second lever cooperates with the rear side of the operating portion 5, and the upper end of the second lever is located at the rear side of the movable portion 22. When the operating portion 5 pushes the lower end of the second lever to move backward, the upper end of the second lever synchronously drives the movable portion 22 to move axially forward, and the movable portion 22 moves axially forward to make way for the hook so that the operating portion 5 is used to drive the fourth locking portion 24 to move to release the lock between the third locking portion 23 and the operating portion 5, that is, the fourth locking portion 24 indirectly realizes locking / unlocking with the third locking portion 23 through the movable portion 22. With this design, the operating part 5 can release the lock between the moving part 22 and the third locking part 23 by moving a small stroke, which is not only conducive to a compact structure, but also more convenient for users to use and easier for users to apply force.

[0073] Attached Figure 6 , 8As shown in FIGS. 14, the moving part 22 and the inverted hook cooperate with each other through the first matching surface 34 and the second matching surface 46 to achieve the upper and lower limit between the moving part 22 and the inverted hook. In order to automatically achieve the mutual cooperation between the moving part 22 and the inverted hook when the upper side depression of the axial support part 4 and the dust can 10 resume the cooperation, the inner side surface of the front side transverse section 35 of the moving part 22 is provided with a guide inclined surface 45, so that when the dust can 10 drives the inverted hook to move together, the inverted hook automatically pushes forward to open the front side transverse section 35 under the guidance of the guide inclined surface 45, and when the upper side depression and the dust can 10 resume the cooperation, due to the absence of the inverted hook blocking, the front side transverse section 35 automatically moves backward under the action of the fourth elastic member 21, thereby automatically completing the upper and lower cooperation between the first matching surface 34 and the second matching surface 46.

[0074] In some embodiments, in order to make the axial support part 4 and the dust cylinder 10 cooperate reliably, Figure 2 , 13 As shown in FIGS. 14 and 15 , the movable portion 22 adopts a frame structure, which includes a front lateral section 35, the rear side of the front lateral section 35 cooperates with the upper end of the second lever, and the example in the attached drawings shows that the third mating surface 47 cooperates with the front side surface of the upper end of the second lever, and the lower side of the front lateral section 35 cooperates with the inverted hook up and down, and the example in the attached drawings shows that the second mating surface 46 is set on the lower side of the front lateral section 35; the axial support portion 4 includes an upper bracket 48 and a lower bracket 49, and the upper bracket 48 and the lower bracket 49 cooperate up and down to form upper and lower limit positions for the axial sections on both sides of the movable portion 22, and the upper bracket 48 and / or the lower bracket 49 are provided with guide portions 50 on both sides, and the axial sections on both sides of the movable portion 22 are guided and cooperated with the corresponding guide portions 50 on both sides. After such design, on the one hand, the frame structure makes the overall strength of the movable part 22 better, and the axial support part 4 includes an upper bracket 48 and a lower bracket 49, which cooperate with each other up and down to form an upper and lower limit for the axial segments on both sides of the movable part 22, and the upper bracket 48 and / or the lower bracket 49 are provided with guide parts 50 on both sides, and the axial segments on both sides of the movable part 22 are guided and cooperated with the corresponding guide parts 50 on both sides, thereby being conducive to providing a stable foundation for limiting the third locking part 23, and frequent use in daily use of the present invention is not easy to cause the movement stability of the movable part 22 to be reduced, thereby being conducive to reliable cooperation between the axial support part 4 and the dust cylinder 10, and being conducive to improving the good sealing and docking performance between the flow channel outlet and the docking interface; on the other hand, in the case where the movable part 22 adopts a frame structure, the axial support part 4 includes an upper bracket 48 and a lower bracket 49, which cooperate with each other up and down to form an assembly structure for the movable part 22, which is conducive to convenient production and stable quality.

[0075] As shown in the example in the drawings, the movable portion 22 includes a rectangular frame consisting of a front transverse section 35, a left axial section 36, a right axial section 37, and a rear transverse section 38.

The connecting vertical portion 54 can be rotatably inserted into the connecting hole 53, so that the fourth locking portion 24 and the movable portion 22 are reliably connected and the structure is compact.

[0078] Furthermore, there are two connecting holes 53, a vertical protrusion 55 is set between the two connecting holes 53, and there are also two connecting vertical parts 54. A vertical groove 39 is set between the two connecting vertical parts 54. The vertical groove 39 guides and cooperates with the vertical protrusion 55, so that the vertical groove 39 can guide the vertical protrusion 55 up and down. After such a design, it is beneficial to the stability of the relative rotation between the fourth locking part 24 and the movable part 22, and it is not easy to shake.

[0079] In some embodiments, Figure 2 , 7 As shown in FIGS. 8 and 16 , when a through hole for the trigger rod 14 to extend out is provided on the annular end surface 41, in order to enable the slider 7 to adapt to the setting requirements of the first lever 33, an arc-shaped transition portion 27 is further provided between the trigger rod 14 and the slider 7, thereby helping to simplify the structure, but the setting position of the slider 7 will not be restricted by the trigger rod 14.
