[0007] In some embodiments, the plug-in end includes a plug-in hole and an annular end surface located circumferentially of the plug-in hole. The annular end surface is provided with a through hole for the trigger rod to extend out. When the operating part is unlocked, the front end of the trigger rod extends out of the through hole. When the accessory is connected to the plug-in end, the end face of the accessory pushes the trigger rod back to generate movement in the first direction.

[0008] In some embodiments, the trigger rod is connected to a first elastic member. When the plug-in end is not connected to an accessory, the first elastic member causes the front end of the trigger rod to extend outside the plug-in end, and the operating part is in an unlocked state. When the plug-in end is connected to an accessory, the accessory pushes the trigger rod back through the front end of the trigger rod, and at the same time, the first elastic member is compressed, and the trigger rod is pushed back to put the operating part in a locked state.

[0009] In some embodiments, a slider is provided between the trigger rod and the operating part. The trigger rod is connected to the slider to drive the slider to move. The operating part is provided with a first lever that cooperates with the slider. One end of the first lever cooperates with the slider, and the other end cooperates with the stop part. When the trigger rod moves along the first direction, the trigger rod drives the slider to cooperate with one end of the first lever to make the first lever swing. The first lever swings so that its other end cooperates with the stop part. The stop part limits the movement of the operating part through the first lever. When the trigger rod moves along the second direction, the trigger rod drives the slider to move in the opposite direction to make the first lever swing in the opposite direction. The first lever swings in the opposite direction to release the other end from the stop part. The stop part releases the restriction on the movement of the operating part.

[0010] In some embodiments, the operating part is provided with a vertical accommodating groove, in which the first lever is connected so as to swing up and down, the upper side of the accommodating groove is opened, and the mating end of the slider is mated with the first lever from the upper side of the accommodating groove, or the lower side of the accommodating groove is opened, and the mating end of the slider is mated with the first lever from the lower side of the accommodating groove.

[0011] In some embodiments, the rear end of the operating part is provided with an opening connected to the vertical accommodating groove, and the other end of the first lever can be exposed through the opening when the first lever swings. The hand-held part is provided with a blocking part on the corresponding side of the opening, which serves as a stop part.

[0012] In some embodiments, the plug-in end includes a plug-in hole and an annular end face located circumferentially of the plug-in hole. The annular end face is provided with a through hole for the trigger rod to extend out. When the operating part is unlocked, the front end of the trigger rod extends out of the through hole. When the accessory is connected to the plug-in end, the end face of the accessory pushes the trigger rod back to generate movement in the first direction; an arc-shaped transition portion is provided between the trigger rod and the slider, and the arc-shaped transition portion positions the slider to the side of the accommodating groove of the operating part.

[0013] In some embodiments, a matching groove is provided on the front side of the trigger of the hand-held portion, which is slidably connected to the operating portion in the front-to-back direction, and the rear end of the matching groove serves as a stop portion.

[0014] In some embodiments, a second elastic member is further included, which is connected to the first lever. When the trigger rod drives the slider to move away from one end of the first lever, the second elastic member provides the first lever with a force to swing in the opposite direction.

[0015] In some embodiments, an operation button is further included, which is connected to the slider. The operation button is used for a user to manually drive the slider to move to lock / unlock the operating part.

[0016] In some embodiments, it also includes a first locking portion, which is connected to the operating button and can move together. The hand-held portion is provided with a fixed second locking portion. The first locking portion and the second locking portion can cooperate with each other to lock / unlock the operating button. When the accessory is connected to the plug-in end, the trigger rod moves along the first direction to drive the slider, the operating button and the first locking portion to move together and finally make the first locking portion cooperate with the second locking portion to lock the operating button. The operating portion is locked. When the accessory is removed from the plug-in end, the slider will not reset in the opposite direction because the operating button is locked, and the operating portion remains locked. When the user manually releases the cooperation between the first locking portion and the second locking portion, the operating button and the slider reset in the opposite direction, and the operating portion is unlocked.

[0017] In some embodiments, the first locking portion includes a first hook, and the second locking portion includes a second hook. The first hook and the second hook can cooperate with each other to lock / unlock the operating button. The user pushes the first hook or the second hook to release the cooperation between the two to release the lock.

Modes for Carrying Out the Invention

[0048] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0049] It should be understood by those skilled in the art that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying 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 disclosure provides a handheld vacuum cleaner, as shown in Figures 1 and 2 , comprising a handheld portion and a dustbin 10. The handheld portion supports the dustbin 10, which is provided with an openable lid 16. The handheld portion is provided with an operating portion 5 and a transmission structure. The operating portion 5 opens the lid 16 via the transmission structure. The handheld portion includes a plug end 13 for connecting an accessory. A trigger lever 14 is provided between the plug end 13 and the operating portion 5. When the accessory is connected to the plug end 13, the accessory drives the trigger lever 14 to move in a first direction to lock the operating portion 5. When the accessory is removed from the plug end 13, the trigger lever 14 moves in a second direction opposite to the first direction to unlock the operating portion 5. Examples of accessories include 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 described herein refers to any structure capable of transmitting the motion of the trigger rod 14 and opening the lid 16. Therefore, there are many different structures, and it is impossible to list them all. The following provides an exemplary transmission structure. This exemplary transmission structure indirectly releases the restraint on the lid 16 by causing the dust bin 10 to swing, thereby opening the lid 16. The specific structure can be found in the following description.

[0053] In some embodiments, the plug end 13 includes a plug hole 40 and an annular end surface 41 located circumferentially around the plug hole 40. The annular end surface 41 is provided with a through hole through which the trigger rod 14 extends. When the operating portion 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 movement in the first direction. As shown in Figures 1 and 11, Figure 1 shows the extended state, while Figure 11 shows the pushed-back state. This design avoids major modifications to the accessory, making the present disclosure compatible with existing accessories. The accessory structure itself does not require any modifications, which helps reduce costs.

[0054] In some embodiments, as shown in FIG2 , the trigger rod 14 is connected to a 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 portion 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 the first elastic member 17 is compressed, pushing the trigger rod 14 back and locking the operating portion 5 . With this structure, when an accessory is removed, the trigger rod 14 can be automatically ejected outward by the first elastic member 17 , ready for the next accessory connection.

[0055] Furthermore, in order to limit the front end of the trigger rod 14 from 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, as shown in Figures 4, 7, 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 in a first direction, the trigger rod 14 drives the slider 7 to cooperate with one end of the first lever 33 to swing the first lever 33. The first lever 33 swings so that its other end cooperates with the stop portion 43. The stop portion 43 restricts the operating part 5 from moving backward through the first lever 33. When the trigger rod 14 moves in a 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 its other end is released from the stop portion 43. If it is retracted into the cooperation groove 44 described below, 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 field of vacuum cleaners described in the present disclosure, because the trigger rod 14 only needs to be extended a little bit, and it is not easy to get caught on other objects, nor is it easy to damage the trigger rod 14.

[0057] As shown in FIG. 16 , a fourth mating surface 52 is provided on the lower side of the slider 7 , and the fourth mating surface 52 is slidably mated with the upper side surface of the first lever 33 .

[0058] In the present disclosure, as shown in Figure 4, the first lever 33 is preferably a lever with one end of the first lever 33 as a rotation fulcrum, and the other end 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 more significantly. In addition, according to the above design, the overall length of the first lever 33 can also be shorter, which is conducive to reducing the axial length dimension of the structure.

[0059] In some embodiments, as shown in Figures 4, 7, 9, and 10, the operating portion 5 is provided with a vertical receiving slot, in which the first lever 33 is connected so as to be able to swing up and down. The upper side of the receiving slot is provided with an opening 42, and the mating end of the slider 7 engages with the first lever 33 from the upper side of the receiving slot. Of course, the lower side of the receiving slot can also be provided with an opening 42, and the mating end of the slider 7 engages with the first lever 33 from the lower side of the receiving slot, as shown in the former. This design is conducive to reducing the size and effectively improving the compactness of the structure. The operating portion 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 slot can ensure that the up and down movement of the first lever 33 is stable and less likely to produce abnormal noise. In addition, the first lever 33 is protected by the receiving slot and will not interfere with other parts and damage the first lever 33, which is conducive to improving reliability.

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

[0061] In some embodiments, as shown in Figures 10 and 11 , the rear end of the operating portion 5 is provided with an opening 42 that communicates with the vertical receiving slot. The other end of the first lever 33 is exposed through the opening 42 when the first lever 33 swings. The handle is provided with a corresponding blocking portion on the side of the opening 42, which serves as a stop 43. This design not only simplifies the structure and solves the problem of locating the stop 43, but also allows the first lever 33 to swing with a smaller amplitude, thereby reducing the exposure of the trigger rod 14.

[0062] In some embodiments, as shown in Figures 11 and 12 , a mating slot 44 is provided on the front side of the trigger 3 of the handheld portion, which is slidably connected to the operating portion 5 in the forward and backward directions. The rear end of the mating slot 44 serves as a stop 43. This not only solves the installation problem of the operating portion 5, but also makes the location very convenient for the user to operate the operating portion 5. Furthermore, the rear end of the mating slot 44 serves as the stop 43, thus also solving the problem of the stop 43's placement. In short, this design not only facilitates operation but also significantly improves the compactness of the structure.

[0063] In some embodiments, as shown in FIG1 , the operating portion 5 is disposed in front of the trigger 3 of the handheld portion, and the space between the operating portion 5 and the trigger 3 accommodates the user's operating finger.

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

[0065] In some embodiments, as shown in FIG4 , a second elastic member 19 is further included. The second elastic member 19 is connected to the first lever 33. When the trigger rod 14 drives the slider 7 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 helps ensure the effective return of the first lever 33 and is less likely to cause malfunctions during frequent use of the product.

[0066] In some embodiments, as shown in FIG4 , an operation button 6 is further included, which is connected to a slider 7. The operation button 6 is used for a user to manually move the slider 7 to lock / unlock the operating portion 5. With this arrangement, the user can lock the operating portion 5 even when no accessories are connected.

[0067] Furthermore, as shown in Figures 4 and 17, 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 cooperate with the second locking portion 9 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 opposite 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 opposite 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 trash, the lock 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, avoiding 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] As shown in Figure 17 , 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 cooperate to lock / unlock the operating button 6. The user pushes the first barb 25 or the second barb 26 to disengage the two, thereby releasing the lock. In this example, the user pushes the first barb 25 to compress the sixth elastic member 31, thereby releasing the engagement between the first barb 25 and the second barb 26. The directions in Figure 17 represent two directions of movement. As shown in the figure, moving the operating button 6 to the right engages the first barb 25 and the second barb 26 to lock. Pressing the first locking portion 8 unlocks the lock, causing the operating button 6 to move in the opposite direction along with the slider 7.

[0069] In some embodiments, referring to Figures 1, 2, 6, 8, 11, and 12, the handheld portion includes a handle 2 and an axial support portion 4 provided on the upper side of the handle 2. The lower end of the handle 2 is connected to the battery portion 1 to achieve wireless operation. The front end of the axial support portion 4 serves as a plug-in terminal 13. The upper side of the axial support portion 4 can swing open the dust bin 10, and further includes a third locking portion 23 and a fourth locking portion 24. The third locking portion 23 swings along with the dust bin 10. When the dust bin 10 is reset, the third locking portion 23 is reset and locked with the fourth locking portion 24. The fourth locking portion 24 is connected to the operating portion 5. 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 fourth locking portion 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 Figures 1 and 2, the upper recess of the axial support portion 4 cooperates with the dust bin 10 in the upper and lower directions. The front end of the upper recess is provided with a limiting surface. Before the dust bin 10 is swung open, the cover 16 is limited by the limiting surface and cannot be opened forward. When the dust bin 10 is swung upward, the cover 16 is freed from the limit of the limiting surface and can be opened. To achieve automatic opening, a torsion spring is provided at the axis of the cover 16, so that the elastic force of the torsion spring causes the cover 16 to automatically open after it is freed from the limit of the limiting surface.

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

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

[0072] In some embodiments, as shown in Figures 2, 3, 5, 7, 8, 13, 14, 15, 18, and 19, the axial support portion 4 is provided with a movable portion 22 that can reciprocate axially, and the third locking portion 23 is provided with a hook. The movable portion 22 and the hook can cooperate up and down to limit the hook. 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. 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. The movable portion 22 moves axially forward to clear the hook to realize the operating portion 5 being 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 portion 5 can release the lock between the movable portion 22 and the third locking portion 23 by moving a relatively small stroke, which not only facilitates a compact structure but also makes it more convenient for users to use and allows users to apply less force.

[0073] As shown in Figures 6, 8, and 14, the movable portion 22 and the hook are engaged with each other via the first mating surface 34 and the second mating surface 46 to achieve upper and lower position limits between the movable portion 22 and the hook. To automatically achieve mutual engagement between the movable portion 22 and the hook when the upper recess of the axial support portion 4 and the dust container 10 are vertically restored, a guide slope 45 is provided on the inner side surface of the front transverse section 35 of the movable portion 22. Thus, when the dust container 10 drives the hook to move, the hook is automatically pushed forward to open the front transverse section 35 under the guidance of the guide slope 45. When the upper recess and the dust container 10 are vertically restored, the front transverse section 35 automatically moves backward under the action of the fourth elastic member 21 due to the absence of the hook blocking it, thereby automatically completing the vertical engagement between the first mating surface 34 and the second mating surface 46.

[0074] In some embodiments, in order to ensure reliable cooperation between the axial support portion 4 and the dust cylinder 10, as shown in Figures 2, 13, 14, and 15, the movable portion 22 adopts a frame structure, which includes a front transverse section 35, the rear side of the front transverse section 35 cooperates with the upper end of the second lever, and the example in the accompanying drawings shows that the third matching surface 47 cooperates with the front side surface of the upper end of the second lever, and the lower side of the front transverse section 35 cooperates with the inverted hook up and down, and the example in the accompanying drawings shows that the second matching surface 46 is set on the lower side of the front transverse 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 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 providing a stable basis for limiting the third locking part 23, and frequent use in daily use of the present invention is not likely to cause the movement stability of the movable part 22 to be reduced, thereby facilitating reliable cooperation between the axial support part 4 and the dust cylinder 10, and facilitating 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 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 accompanying 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 front transverse section 35 is provided with a third mating surface 47 and a guide inclined surface 45 distributed above and below.

[0076] As shown in the example in the accompanying drawings, on the axial movement path of the left axial segment 36 and the right axial segment 37, the upper bracket 48 is provided with an upper limit rib 51, and the lower bracket 49 is provided with a guide groove. The upper limit rib 51 and the guide groove together constitute the axial guidance and upper and lower support for the left axial segment 36 and the right axial segment 37.

[0077] In some embodiments, as shown in Figures 13, 14, 18, and 19, the second lever serving as the fourth locking portion 24 is provided with a connecting hole 53, and the front transverse section 35 is provided with a corresponding connecting vertical portion 54. The connecting vertical portion 54 can be rotatably inserted into the connecting hole 53, so that the fourth locking portion 24 is reliably connected to the movable portion 22, and the structure is compact.

[0078] Furthermore, there are two connecting holes 53, and a vertical protrusion 55 is set between the two connecting holes 53. There are also two connecting vertical parts 54, and 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, as shown in Figures 2, 7, 8, and 16, when a through hole is provided on the annular end surface 41 for the trigger rod 14 to extend out, 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.

[0080] In some embodiments, as shown in Figures 3, 4, 7, and 8, in order to enable the dust cup 10 to swing effectively, a top column 28 and a fifth elastic member 29 are further provided on the lower side of the dust cup bracket 11, and the top column 28 provides an upward pushing force.

[0081] In the present disclosure, a third elastic member 20 is provided to automatically reset the operating portion 5 , and a seventh elastic member 32 is provided to automatically reset the slider 7 .

[0082] When understanding the present disclosure, if necessary, the above structure can be understood with reference to other embodiments / drawings, and will not be described in detail here.

[0083] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
