[0077] Embodiment I

[0078] This embodiment mainly describes an exemplary structure of the dust cup 1.

[0079] Please refer to FIGS. 1 and 2, the dust cup 1 has a cup body 10 and a cup cover assembly 2 pivotally connected to the cup body 10, the cup body 10 is preferably cylindrical, comprising a bottom wall 12 and a peripheral side wall 11 arranged on the bottom wall 12, and the peripheral side wall 11 is provided with a dust discharge port 111 near the bottom wall 12, the cup cover assembly 2 comprises a normally closed cover plate 21 arranged on the dust discharge port 111 and a locking assembly 22 locking the normally closed cover plate 21.

[0080] Referring to FIGS. 1-3, the normally closed cover plate 21 is pivotally connected to the cup body 10 by a pivot shaft 211, and covers the dust outlet 111 in a manner that the normally closed cover plate 21 can be opened to open the dust outlet 111 and closed to close the dust outlet 111, and is adapted to be opened by an external suction force so that the garbage in the cup body 10 can be discharged from the dust outlet 111.

[0081] The locking assembly 22 is arranged close to the pivot shaft 211, and is used to keep the normally closed cover plate 21 in a locked state to avoid the garbage from being discharged due to the automatic opening of the normally closed cover plate 21.

[0082] Referring to FIG. 3, in an embodiment, a torsion spring 212 is connected between the normally closed cover plate 21 and the cup body 10, and the torsion spring 212 is sleeved on the pivot shaft 211, so that the normally closed cover plate 21 is always closed relative to the dust outlet 111 of the cup body 10. During the opening of the normally closed cover plate 21 by an external force, the torsion spring 212 accumulates energy; when the external force is removed, the normally closed cover plate 21 is gradually closed on the dust outlet 111 under the torsion of the torsion spring 212. The external force can be the suction force generated by the dust collection station 3, that is, the normally closed cover plate 21 can be opened under the negative pressure.

[0083] Referring to FIGS. 3-5, in an embodiment, the locking assembly 22 includes a pressing plate assembly 221 and an elastic member, and the pressing plate assembly 221 is pressed against the cup body 10 by the elastic member.

[0084] The pressing plate assembly 221 is arranged close to the pivot shaft 211 between the normally closed cover plate 21 and the cup body 10, and the elastic member is preferably a compression spring 222, which is pressed between the cup body 10 and the pressing plate assembly 221, and can be compressed and stored energy when the pressing plate assembly 221 is forced to move away from the normally closed cover plate 21, and releases potential energy to move the pressing plate assembly 221 towards the normally closed cover plate 21 to press the normally closed cover plate 21 against the cup body 10 when the external force on the pressing plate assembly 221 disappears.

[0085] Please refer to FIGS. 4, 8-12, the dust collector device 100 is placed on the dust collection station 3 in the first direction, and the movement direction of the pressing plate assembly 221 is parallel to the first direction.

[0086] As can be seen from the above, in the embodiment, the dust outlet 111 is formed on the peripheral sidewall 11 of the cup body 10, so the first direction is the vertical direction, the pressing plate assembly 221 slides up and down along the axial direction of the cup body 10, and the sliding direction of the pressing plate assembly 221 is parallel to the axial direction of the cup body 10 and the first direction. Thus, the structure of the docking and unlocking is optimized, the docking process is smoother, and the user experience is improved.

[0087] In combination with FIG. 3 and FIG. 5, the cup body 10 is provided with a sliding space 114, and the pressing plate assembly 221 is embedded in the sliding space 114 and can slide along the sliding space 114. Preferably, the sliding space 114 is provided with a limiting protrusion 115 at one end close to the rotating shaft 211, which is used to limit the sliding stroke of the pressing plate assembly 221. When the pressing plate assembly 221 slides a predetermined distance in the direction close to the normally closed cover plate 21, i.e., slides to the position, it is stopped by the limiting protrusion 115.

[0088] In combination with FIG. 7, FIG. 10 and FIG. 12, the outer middle part of the pressing plate assembly 221 is provided with a touch block 2211. During the installation of the dust cup 1 on the dust collecting station 3, the touch block 2211 can be touched and pressed by the corresponding unlocking contact 32 on the dust collecting station 3, so as to move the pressing plate assembly 221 in the direction away from the normally closed cover plate 21, thereby releasing the locking of the normally closed cover plate 21, and enabling the normally closed cover plate 21 to be opened under the action of external force.

[0089] In combination with FIG. 3, the outer side wall of the normally closed cover plate 21 is provided with a let-in groove 213 at the position corresponding to the sliding space 114, which is used to let in the sliding of the unlocking contact 32 on the dust collecting station 3.

[0090] In combination with FIG. 29, the pressing plate assembly 221 has a pressing end 2213 which is slidably pressed on the side of the normally closed cover plate 21 away from the dust discharging port 111. The end of the pressing end 2213 has a second guide inclined surface 2215, which is used to facilitate the sliding of the pressing end 2213 on the normally closed cover plate 21.

[0091] As shown in FIG. 3 and in combination with FIG. 27 and FIG. 29, the end of the pressing plate assembly 221 away from the pressing end 2213 is provided with a spring mounting cavity 2212, and one end of the compression spring 222 is mounted in the spring mounting cavity 2212.

[0092] In combination with FIG. 3, the cup body 10 is further provided with a decorative cover 113, and the cup body 10 is further provided with a decorative cover mounting structure 112. The decorative cover 113 is detachably connected with the decorative cover mounting structure 112, for example, is snap-connected, and is mounted on the cup body 10, which is used to shield the locking assembly 22 and its sliding space 114, so as to make the dust cup have a better appearance effect.

[0093] In addition, the outer contours of the decorative cover 113, the normally closed cover plate 21 and the cup body 10 are circumferentially arranged when the normally closed cover plate 21 is closed on the dust discharging port 111, which avoids the protrusion from the contour setting causing the normally closed cover plate 21 to be accidentally opened by mistake, thereby affecting the use experience.

[0094] Embodiment Two

[0095] Please refer to FIG. 4-6, in the embodiment, the dust collector device 100 of the present disclosure comprises a cleaning main body 4, a handle 41 connected with the cleaning main body, a first suction source 42 arranged in the cleaning main body 4 and the dust cup 1 described above. Since the dust collector has the dust cup 1, it also has the beneficial effects thereof, which are not repeated here.

[0096] When the locking assembly 22 is provided with a slidable pressing plate assembly 221, the sliding direction of the pressing plate assembly 221 is parallel to the axis of the first suction source 42.

[0097] In addition, the movement direction of the pressing plate assembly 221 and the extension axis of the handle 41 form an included angle, and the angle of the included angle is 80°-140°. The included angle optimizes the structure of the docking unlocking while ensuring the comfort of holding the handle 41, making the docking process smoother and improving the user experience.

[0098] Embodiment three

[0099] Referring to FIG. 13 to FIG. 19, the embodiment mainly describes another exemplary structure of the dust cup 1.

[0100] As shown in FIG. 13-19, the dust cup 1 has a cup body 10 and a cup cover assembly 2 pivotally connected with the cup body 10. Preferably, the cup body 10 is generally cylindrical, comprising a circular bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12, and a dust discharge port 111 is formed in the bottom wall 12. The cup cover assembly 2 is arranged at the bottom of the cup body 10, which comprises a normally closed cover plate 21 covering the dust discharge port 111. The normally closed cover plate 21 covers the dust discharge port 111 in an opening state and closes the dust discharge port 111 in a closed state. The normally closed cover plate 21 also has a locked and unlocked state when closing the dust discharge port 111. In the unlocked state, the normally closed cover plate 21 remains closed without external suction force, and opens under the action of external suction force, so that the garbage in the cup body 10 can be discharged from the dust discharge port 111.

[0101] The normally closed cover plate 21 is pivotally connected with the cup body 10 through a rotating shaft 211, and the cup cover assembly 2 comprises a locking assembly 22 for locking the normally closed cover plate 21, which is used to keep the normally closed cover plate 21 in the locked state to avoid automatic opening of the normally closed cover plate 21 causing garbage leakage.

[0102] In combination with FIG. 12 and FIG. 15, in one embodiment, a torsional spring 212 is connected between the normally closed cover plate 21 and the cup body 10, and the torsional spring 212 is sleeved on a pre-designed torsional spring mounting portion 2121 of the normally closed cover plate 21, so that the normally closed cover plate 21 is always closed relative to the dust discharge port 111 of the cup body 10. During the opening process of the normally closed cover plate 21 under the action of suction force, the torsional spring 212 accumulates the ability; when the external force is removed, the normally closed cover plate gradually closes on the dust discharge port 111 under the action of the torsional force of the torsional spring 212.

[0103] The suction force can be a suction force generated by the dust collection station 3, or a wind channel connection is established between the dust collection station and a suction motor of the vacuum cleaner device, and a motor in the vacuum cleaner is used to provide negative pressure in the dust collection station 3 to generate the suction force, that is, the normally closed cover plate 21 can be opened under the action of the negative pressure. In the second way of generating the suction force, the dust collection station 3 can not be provided with a motor, thereby reducing the cost and reducing the volume of the dust collection station 3.

[0104] In an embodiment, the torsional spring mounting portion 2121 is a rotating shaft for pivotally connecting the normally closed cover plate 21 and the cup body 10.

[0105] In an embodiment, as shown in FIG. 14, the locking assembly 22 includes a pressing plate assembly 221 and an elastic member, and the pressing plate assembly 221 presses the normally closed cover plate 21 against the cup body 10 under the action of the elastic member.

[0106] The pressing plate assembly 221 is arranged close to the rotating shaft 211 between the normally closed cover plate 21 and the cup body 10, and the elastic member is preferably a compression spring 222, which is pressed between the cup body 10 and the pressing plate assembly 221, and can be compressed and stored energy when the pressing plate assembly 221 is moved in a direction away from the normally closed cover plate 21 under an external force, and releases potential energy to move the pressing plate assembly 221 in a direction close to the normally closed cover plate 21 after the external force disappears, thereby pressing the normally closed cover plate 21 against the dust discharge port 111 of the cup body 10.

[0107] The dust collection station 3 is arranged on the cup body 10 in a first direction (e.g., a vertical direction from top to bottom), and the movement direction of the pressing plate assembly 221 is perpendicular to the first direction, that is, the pressing plate assembly 221 slides in a horizontal direction.

[0108] As described above, in the embodiment, the dust discharge port 111 is arranged on the bottom wall 12 of the cup body 10, the first direction is a vertical direction, the pressing plate assembly 221 slides in a horizontal direction perpendicular to the axis of the cup body 10, and the sliding direction of the pressing plate assembly 221 is perpendicular to the first direction and the axis of the cup body 10. The outer side of the pressing plate assembly 221 is provided with a first unlocking inclined surface 2216, which is used to be pressed by an unlocking contact on the dust collection station 3 to push the pressing plate assembly 221 in a direction away from the normally closed cover plate 21, thereby separating from the normally closed cover plate 21 and unlocking the normally closed cover plate 21. Since the cup cover assembly 2 is arranged on a circular bottom wall, the length direction of the unlocking contact on the dust collection station 3 is arranged in parallel to the docking direction, so that in the docking process of the dust cup 1 and the dust collection station 3, the unlocking contact is guided to press and push the pressing plate assembly 221 through the inclined surface of the first unlocking inclined surface 2216, so that the pressing plate assembly 221 slides in a direction perpendicular to the docking direction of the dust collection station 3, and the unlocking of the normally closed cover plate 21 is completed in the docking process. Therefore, the structure of the docking and unlocking is optimized, the whole docking process is smoother, and the user experience is improved.

The cleaning main body 4 is provided with a handle 41 on the outside for a user to hold. The cleaning main body 4 is provided with a first suction source, which is a suction motor, used for generating suction force to suck garbage into the dust cup 1. Since the dust collector apparatus 100 has the above-mentioned dust cup 1, it also has the beneficial effects thereof, which will not be repeated here.

[0123] When the locking assembly 22 is provided with the slidable pressing plate assembly 221, the sliding direction of the pressing plate assembly 221 is perpendicular to the axis of the first suction source.

[0124] Embodiment Five

[0125] The prior art dust collector also has the following problems: the existing dust collector cover plate is mounted on the outside of the dust cup of the dust collector, in addition, the connection structure and the locking structure between the dust collector cover plate and the dust cup of the dust collector are complex, resulting in that the size of the dust cup of the dust collector is large, which is not conducive to miniaturization, especially the miniaturization of the handheld dust collector.

[0126] Referring to Figs. 24-32, the dust cup 1 is adapted to be mounted to a cleaning body of a dust cleaner device for receiving garbage sucked by the cleaning body. The cup body 10 is internally recessed with a cover body mounting cavity 110, and the cup cover assembly 2 is embedded in the cover body mounting cavity 110, thereby reducing the overall size of the dust cup 1 and achieving miniaturization of the dust cup 1 and the cleaning device (e.g., a dust cleaner) using the dust cup 1.

[0127] Referring to Fig. 24, in an embodiment, the cup body 10 includes a generally cylindrical barrel, which includes a circular bottom wall 12 and a peripheral side wall 11 disposed around the bottom wall 12. The bottom wall 12 or the peripheral side wall 11 is provided with a dust discharge port 111. The structure of the cup body 10 of the embodiment of the disclosure will be described below with the dust discharge port 111 provided on the peripheral side wall 11 as an example.

[0131] The dust cup 1 of the embodiment of the disclosure internally recesses the cover body mounting cavity 110 on the barrel of the cup body 10, and the cup cover assembly 2 is received in the cover body mounting cavity 110, so that the cup cover assembly 2 does not increase the size of the dust cup 1, which is beneficial to miniaturization of the dust cup 1 and the dust cleaner device using the cup body 10.

[0132] In an embodiment, the normally closed cover plate 21 includes a cover plate 214, one end of which is formed with a hinge joint 2141 provided with a rotating shaft 211. The hinge joint 2141 is placed between the two hinge plates and is inserted into the hole position of the hinge plates through the rotating shaft 211, thereby achieving the pivotal connection between the cover plate and the barrel.

[0133] In addition, the cup cover assembly 2 further comprises a torsion spring 212 sleeved on the rotating shaft 211 and making the normally closed cover plate 21 normally closed relative to the dust outlet 111. Specifically, during the opening of the normally closed cover plate 21, the torsion spring 212 is twisted to store energy, and after the external force on the normally closed cover plate 21 is removed, the torsion of the torsion spring 212 makes the normally closed cover plate 21 reset to cover the dust outlet 111, so that the normally closed cover plate 21 is automatically reset or kept in the normally closed state of the dust outlet 111.

[0134] The cup cover assembly 2 is further provided with a locking assembly 22 for slidably locking the normally closed cover plate 21 to prevent the normally closed cover plate 21 from being automatically opened or prematurely opened to cause the leakage of garbage (such as dust) in the cup body 10.

[0140] In an embodiment, as shown in FIG. 29, the outside of the pressing plate assembly 221 is provided with a pressing block 2211, and the pressing block 2211 is used to be pressed by the external structure to push the pressing plate assembly 221 to move away from the normally closed cover plate 21 so as to separate from the normally closed cover plate 21 and unlock the normally closed cover plate 21.

[0141] In combination with FIG. 26 and FIG. 27, the outside of the normally closed cover plate 21 is provided with a displacement slot 213 corresponding to the position of the pressing plate assembly 221, which extends along the movement direction of the pressing plate assembly 221. The displacement slot 213 is used for displacement of the external unlocking structure, so that during the process of placing the cup body 10 at the dust collecting station, the external unlocking structure moves upward relative to the normally closed cover plate 21, pushes the pressing block 2211 on the pressing plate assembly 221 to make the pressing plate assembly 221 move upward and separate from the normally closed cover plate 21, thereby unlocking the normally closed cover plate 21.

[0142] In an embodiment, as shown in FIG. 29, the pressing end 2213 is provided with a second guide inclined surface 2215, which is used for facilitating the sliding of the pressing end 2213 on the normally closed cover plate 21 to press the normally closed cover plate 21.

[0143] In an embodiment, in combination with FIG. 3 and FIG. 30, the cover mounting cavity 110 of the cup body 10 is provided with a decorative cover mounting structure 112 on both sides of the dust discharging port 111, and the decorative cover mounting structure 112 is provided with a decorative cover 113. The decorative cover 113 is provided with a mounting gap 231 for mounting and moving the normally closed cover plate 21, and the normally closed cover plate 21 is embedded in the mounting gap 231. It can be understood that the decorative cover is also provided with a displacement gap for displacement of the movement of the pressing block 2211, which is communicated with the mounting gap 231.

[0144] In an embodiment, as shown in FIG. 3, FIG. 24 and FIG. 30, the decorative cover mounting structure 112 is provided with a pair of hooks 117 and a pair of elastic buckles 118, and the inner side of the decorative cover 113 is provided with a hook 232 and a buckle 233 corresponding to the hooks 117 and the elastic buckles 118, respectively.

Among them, the hook 232 is hooked with the hook 117, and the elastic buckle 118 is buckled in the buckle 233.

[0145] By providing the decorative cover 113, the overall appearance effect of the dust cup 1 is improved, and by buckling connecting the decorative cover 113 with the barrel, the installation of the decorative cover 113 is facilitated.

[0146] In combination with FIG. 26 and FIG. 28, in an embodiment, the cup cover assembly 2 further comprises a sealing piece 24 for sealing between the cup cover assembly 2 and the dust discharging port 111 of the cup body 10. The inner side of the normally closed cover plate 21 is provided with an embedding groove 2113, and the sealing piece 24 is embedded in the embedding groove 2113. By providing the sealing piece 24 between the normally closed cover plate 21 and the dust discharging port 111, the sealing performance of the dust cup 1 is improved, and dust leakage from the joint between the dust discharging port 111 and the normally closed cover plate 21 is avoided.

[0147] In addition, the outer contour of the decorative cover 113, the normally closed cover plate 21 and the barrel body are coaxial when the normally closed cover plate 21 is closed on the dust discharge port 111, so that the overall size of the dust cup 1 is small, and the overall appearance effect of the dust cup 1 is further improved.

[0149] In this embodiment, a gun type handheld dust collector (also referred to as a dust collector device 100) is provided, which has a cleaning main body, a handle connected outside the cleaning main body, a main machine motor arranged in the cleaning main body, and the dust cup 1 of embodiment five installed on the cleaning main body. The cleaning main body further comprises an air inlet pipe in communication with the cup body 10.

[0150] Among them, different from the structure that the handle and the air inlet pipe of some current random suction or dust collectors are almost arranged in a straight line, the central axis of the air inlet pipe and the axis of the handle of the gun type handheld dust collector are arranged at an angle, and the angle of the angle is 80°-150°. When it is necessary to use the dust collecting station to clean the gun type handheld dust collector, the user places the gun type handheld dust collector on the dust collecting station by holding the handle 31 of the gun type handheld dust collector to complete the docking of the two. Since the dust collecting station has an opening at the upper end, and the user needs to place the dust collector from above the dust collecting station towards the opening direction of the base station, so that the slide rod assembly 223 on the barrel body can cooperate with the unlocking contact of the dust collecting station, therefore, setting the angle in the range of 80°-150° can reduce the wrist pressure of the user in this operation process, and optimize the user's use experience.

[0151] Embodiment seven

The dust cup 1 is installed to the upper end of the abutment portion 31 when docking, the dust collection cavity 34 is in communication with the abutment portion 31 through an airflow passage, the abutment portion 31 is in communication with the dust discharge port 111 of the dust cup 1 after docking of the dust cup 1 and opening of the normally closed cover plate 21 of the dust cup 1, and the second suction source 33 is used to generate a suction airflow in the airflow passage to suck open the normally closed cover plate 21 in the unlocked state, thereby transferring garbage in the dust cup 1 to the dust collection cavity 34 through the dust discharge port 111.

[0160] Correspondingly, the abutting portion 31 is provided with an unlocking contact 32 at a position corresponding to the contact block 2211 of the pressing plate assembly 221, which can abut against the contact block 2211 during the installation of the dust cup 1 on the integrated station 3, thereby pushing the pressing plate assembly 221 to slide in a direction away from the normally closed cover plate 21, separating the pressing plate assembly 221 from the normally closed cover plate 21, unlocking the normally closed cover plate 21, and enabling the normally closed cover plate 21 to be opened under the action of the suction airflow, so that the garbage in the dust cup 1 can be sucked into the dust collection cavity 32 from the dust discharge port 121 by the suction airflow of the second suction source 33.

[0161] Optionally, the movement direction of the pressing plate assembly 221 is perpendicular to the axis of the second suction source 33.

[0162] The dust collector device 100 is placed on the dust collection station 3 in the first direction, and the movement direction of the pressing plate assembly 221 is perpendicular to the first direction, so that during the placement of the dust collector device 100, the unlocking contact 32 can be aligned with the contact block 2211 of the pressing plate assembly 221 and push the pressing plate assembly 221 along the preset trajectory to complete the unlocking of the normally closed cover plate 21.

[0164] Embodiment Nine

[0165] In combination with FIGS. 1-33, the cleaning system 200 of the present embodiment is composed of the dust collector device 100 of embodiment two or six and the dust collection station 3 of embodiment seven, or composed of the dust collector device 100 of embodiment four and the dust collection station 3 of embodiment eight, and thus also has the beneficial effects of the above-mentioned dust collector device 100 and dust collection station 3, i.e., the unlocking of the normally closed cover plate 21 can be completed during the placement of the dust collector device 100 on the dust collection station 3, so that the normally closed cover plate 21 can be opened under the action of the suction force to complete the transfer of the garbage in the dust cup 1. In addition, the normally closed cover plate 21 will not be automatically opened after the unlocking of the locking assembly 22, and needs to be opened under the action of the suction force, thereby avoiding the premature opening of the dust discharge port 111 during the installation or use of the dust cup 1, which can cause the dust in the dust cup 1 to be prematurely leaked, and improving the user experience.

[0166] Embodiment Ten

[0167] In combination with FIGS. 9-12, in the present embodiment, after the locking assembly 22 of the cup cover assembly 2 releases the lock of the normally closed cover plate 21, the normally closed cover plate 21 can be opened under the action of external suction force. The external suction force is derived from the negative pressure transmitted in the dust collection station 3. The negative pressure in the dust collection station 3 is derived from at least two ways, one of which is to set a suction motor (i.e., the second suction source 33) in the dust collection station 3 to generate suction force; the other is to establish an air duct connection between the dust collection station 3 and the suction motor (i.e., the first suction source 42) of the dust collector device 100, and use the motor in the dust collector to provide negative pressure for the dust collection station 3. The dust collection station can not be provided with a motor, which reduces the cost and can reduce the volume of the dust collection station 3.

[0168] By setting the cup cover assembly 2 as normally closed, the dust outlet 111 is opened only under the action of external suction force, avoiding the dust outlet 111 being opened in advance to cause dust leakage, and improving the user experience.
