[0002] As living standards improve, people's expectations for their home environments are becoming increasingly higher. To meet these growing needs, a variety of smart home appliances have emerged on the market. Vacuum cleaners, due to their ease of operation and ease of use, are increasingly becoming part of people's lives, becoming integral to homes and offices, and becoming a crucial and popular small appliance.

[0003] To further enhance the user experience, existing vacuum cleaners often include a dust collection station that works in conjunction with the vacuum cleaner. The dust collection station can be used to store and clean the vacuum cleaner. When the user needs to clean the dust cup, the vacuum cleaner can be placed in the dust collection station. The dust collection station unlocks and opens the vacuum cleaner cover, allowing the dust in the dust cup to be poured out from the dust outlet, thus completing the cleaning process.

[0004] Existing vacuum cleaners have the following problems: when installed on the dust collection station, the dust cup cover is opened before the dust cup is installed in place, causing the dust in the dust cup to leak out. Some dust will remain at the position where the dust collection station and the cover are connected, and the dust will also cover the cover. When the vacuum cleaner equipment is taken out of the dust collection station, the dust will be brought out to the external space, affecting the user experience. Utility Model Content

[0047] Example 1

[0048] See also Figures 1 to 8The present invention provides a gun-type handheld vacuum cleaner 100 and a cleaning system. The gun-type handheld vacuum cleaner 100 includes a cleaning body 1, a handle 3 connected to one side of the cleaning body 1, a suction motor 11 disposed within the cleaning body 1, and a dust cup assembly 2 mounted below the suction motor 11. The dust cup assembly 2 includes a dust cup 21, a dust cup cover 22, and a separator 24. The dust cup has a dust discharge port 211, and the dust cup cover 22 is rotatably mounted on the dust discharge port 211. The separator 24 is disposed within the dust cup 21. The suction motor 11 is configured to provide a suction airflow to draw dirt into the dust cup assembly 2. The separator 24 is configured to separate dust from air in the dirt. The separator 24 has a first axis, and the suction motor 11 has a second axis.

[0049] The cleaning system is composed of the above-mentioned gun-type handheld vacuum cleaner 100 and the dust collection station 200. The integrated station 200 is used to open the dust cup cover 22 of the dust cup assembly 2 to expose the dust outlet 211, transfer and store the dirt in the dust cup assembly 2 of the gun-type handheld vacuum cleaner 100.

[0050] Please combine Figure 2 and Figure 3 The dust cup 21 includes a circular bottom wall and a side wall arranged around the edge of the circular bottom wall. The side wall is concave near the bottom end to form a mounting portion, and the mounting portion is provided with the dust discharge port 211. Preferably, the dust discharge port 211 and the handle 3 are respectively arranged on both sides of the first axis.

[0051] The dust cup cover 22 is arranged in the installation part, which includes a movable cover 22 and a locking assembly 23. When the movable cover 21 is arranged at the dust exhaust port 211, it is located within the outer contour of the dust cup 21, so as not to increase the size of the dust cup assembly additionally, thereby realizing the miniaturization of the dust cup assembly.

[0052] The movable cover 22 and the dust cup 21 can be movably connected (for example, pivotally connected) to open or close the dust outlet 211. The locking assembly 23 is used to press the movable cover 22 against the dust outlet 211 from the outside of the movable cover 22 to achieve the locking function of the movable cover 22. The locking assembly 23 can also be separated from the movable cover 22 under the action of external force to achieve the unlocking function of the movable cover 22.

[0053] As a preferred embodiment, the dust cup 21 is a cylindrical dust cup, and the axis of the cylindrical dust cup is arranged colinearly with the first axis of the separator 24 and the second axis of the suction motor 11.

[0054] Please combine Figure 4The locking assembly 23 includes a pressure plate assembly 231 and an elastic member. The pressure plate assembly 231 can be slidably pressed on the outer side of the movable cover 22. The elastic member is pressed against one end of the pressure plate assembly 231, so that the pressure plate assembly 231 has a tendency to slide toward the movable cover 22. Specifically, the elastic member is compressed and accumulates elastic potential energy when the pressure plate assembly 231 is forced to move in a direction away from the movable cover 22. When the external force applied to the pressure plate assembly 231 is removed, the pressure plate assembly 231 is driven to move toward the movable cover 22, so that the pressure plate assembly 231 presses the movable cover 22 from the outside of the movable cover 22, that is, the pressure plate assembly 231 can slide back and forth in a direction away from the movable cover 22 or close to the movable cover 22.

[0055] In this embodiment, the pressure plate assembly 231 slides linearly in a vertical direction, and the sliding direction is parallel to the first axis of the separator 24 and the second axis of the suction motor 11. The gun-type handheld vacuum cleaner 100 is mated with or separated from the dust collection station 200 along the extended axis of the dust cup 21. When the dust cup cover is disposed on the peripheral side wall, the rotation axis of the movable cover 22 is perpendicular to the extended axis of the dust cup 21, that is, the movable cover 22 flips up and down along the extended axis of the dust cup 21 to open and close. In this way, when the dust cup 21 is closed, the movable cover 22 can be closed by its own gravity. Furthermore, the sliding direction of the pressure plate assembly 231 is parallel to the extended axis of the dust cup 21. The elastic member in the locking assembly 23 only needs to provide force to move the pressure plate assembly 231 to a position that locks the movable cover 22, without providing force to close the movable cover 22. This reduces the performance requirements of the elastic member, helping to reduce costs. Furthermore, even if the elastic member fatigues and degrades over time, the locking effect of the movable cover can still be ensured, reducing failure rates and helping to extend service life.

[0056] The dust discharge direction of the dust cup 21 is substantially perpendicular to the reciprocating motion direction of the pressure plate assembly 231. The term "substantially perpendicular" means that the two directions are theoretically perpendicular to each other, but in practice, due to errors in design, production, and assembly, the angle between the two directions may fluctuate within a certain range above or below 90°, for example, between 85° and 95°.

[0057] In addition, the sliding direction of the pressure plate assembly 231 forms an angle with the axis of the handle 3, and the angle of the angle is 80°-150°. When the dust collecting station 200 needs to be used to clean the gun-type handheld vacuum cleaner 100, the user places the gun-type handheld vacuum cleaner 100 on the dust collecting station 200 by holding the handle 3 of the gun-type handheld vacuum cleaner 100 to complete the docking of the two. Since the upper end of the dust collecting station 200 is open, and the user needs to place the vacuum cleaner from the top of the dust collecting station 200 toward the opening direction of the base station so that the pressure plate assembly 231 on the dust cup assembly 2 can cooperate with the unlocking contact of the dust collecting station 200, setting the angle within the range of 80°-140° can reduce the pressure on the user's wrist during this operation and optimize the user experience.

[0058] A sliding space 212 is provided on the side wall of the dust cup 21 at a position corresponding to the dust outlet 211 , and the pressure plate assembly 231 and the elastic member are both provided in the sliding space 212 .

[0059] A limiting protrusion 213 for limiting the sliding travel of the pressing plate assembly 231 is provided on one side of the sliding space 212 away from the dust exhaust port 211 .

[0060] Please combine Figure 5 The pressing plate assembly 231 has a pressing end 2311 , and the pressing end 2311 has a guiding slope, which is used to facilitate the pressing end 2311 to slide to the outside of the movable cover 22 .

[0061] A touch panel 2313 is provided on the outer side of the pressure plate assembly 231. The touch panel 2313 is used to receive external pressure to separate the pressure plate assembly 231 from the movable cover 22, thereby unlocking the movable cover 22. In one embodiment, the touch panel 2313 can be pressed by an unlocking contact on the docking portion 210 of the dust collection station 200, thereby unlocking the movable cover 22.

[0062] Please combine Figure 2 A clearance groove 221 is provided on the outer side of the movable cover 22 corresponding to the touch plate 2313. The clearance groove 221 is used to make way for the unlocking contact on the docking part 210 of the dust collecting station 200 when the gun-type handheld vacuum cleaner 100 is placed on the dust collecting station 200 for dust discharge, so that the unlocking contact presses against the touch plate 2313 to push the pressure plate assembly 231 to slide.

[0063] Please combine Figure 4 Preferably, the elastic member is a compression spring 232, and the end of the pressure plate assembly 231 away from the movable cover 22 is provided with a spring mounting portion, and the spring mounting portion is preferably a spring mounting cavity 2312. One end of the compression spring 232 is inserted into the spring mounting cavity 2312, and the other end of the compression spring 232 (i.e., the clamping end 2311) presses against the dust cup 21 to make the pressure plate assembly 231 slide in a straight line.

[0064] By optimizing the sliding direction of the pressure plate assembly 231 so that it is parallel to the axis of the suction motor 11, the separator 24 and the dust cup 21, the locking assembly 23 can unlock the movable cover 22 when the gun-type handheld vacuum cleaner 100 is placed on the integrated station, making it more convenient to use the gun-type handheld vacuum cleaner and improving the user experience.

[0065] Example 2

[0066] The present invention also provides another gun-type handheld vacuum cleaner 100, which is substantially the same as the first embodiment, except that:

[0067] Please combine Figure 8 The gun-style handheld vacuum cleaner 100 also includes an air inlet pipe 4 in fluid communication with a dust cup 21. The axis of the dust cup 21 is positioned above the handle 3, with the central axis of the air inlet pipe 4 as the horizontal axis. The dust cup 21 is spaced apart from the handle 3 on either side of the central axis of the air inlet pipe 4, ensuring that the dust cup is positioned as far away from the user's grip as possible, thus preventing the dust cup from contaminating the user's hands during cleaning.

[0068] Example 3

[0069] The present invention also provides another gun-type handheld vacuum cleaner 100, which is substantially the same as the first embodiment, except that:

[0070] Please combine Figure 9 The gun-type handheld vacuum cleaner 100 includes a cleaning body 1, a suction motor 11 provided at one end of the cleaning body, a dust cup assembly 2 installed below the suction motor 11 and coaxially arranged with the suction motor, and a handle 3. The handle 3 is connected to the cleaning body 1 below the axis of the cleaning body 1 and is located on one side of the axis of the suction motor 11.

[0071] In one embodiment, the pressure plate assembly 231 and the handle 3 are disposed on both sides of the second axis of the suction motor 11 .

[0072] In one embodiment, the sliding direction of the pressing plate assembly 231 is parallel to the second axis of the suction motor 11. The sliding direction of the pressing plate assembly 231 forms an angle with the axis of the handle 3, and the angle is 30°-75°.

[0073] Example 4

[0074] Please combine Figures 1 to 9 The utility model also provides a cleaning system, including the above-mentioned gun-type handheld vacuum cleaner 100 and a dust collection station 200 matched with the gun-type handheld vacuum cleaner 100, the dust collection station 200 is used to place the gun-type handheld vacuum cleaner 100, and can transfer the garbage in the dust cup of the gun-type handheld vacuum cleaner 100 to the dust collection station 200.

[0075] The dust collection station 200 includes a docking portion 210, a dust collection chamber 220, and a base station motor 230, which are arranged in sequence. The docking portion 210 has a cavity for accommodating at least the portion of the dust cup assembly 2 including the dust cup cover. After the docking portion 210 is docked with the dust cup assembly 2 and the movable cover 22 of the dust cup is opened, it is connected to the dust discharge port 211 of the dust cup. The dust collection chamber 220 is connected to the docking portion 210 through an air flow channel and is used to store garbage discharged by the vacuum cleaner 100. The base station motor 230 is used to generate a suction airflow in the airflow channel. The suction airflow can switch the movable cover 22 from a closed state to an open state, and extract the garbage in the dust cup assembly 2 from the dust discharge port 211.

[0076] When the gun-type handheld vacuum cleaner 100 is placed on the corresponding dust collecting station 200 for dust removal, the dust cup is connected to the dust collecting station 200 at the docking portion 210, and the movable cover 22 is switched from the closed state to the open state under the suction force of the dust collecting station 200, so that the dust collecting chamber 220 on the dust collecting station 200 is connected to the dust exhaust port 211.

[0077] In addition, the dust collection station 200 is also provided with an unlocking contact at the docking part 210 that can act on the touch plate 2313 of the pressure plate assembly 231. When the gun-type handheld vacuum cleaner 100 is placed on the docking part 210, the unlocking contact pushes the touch plate 2313 to cause the pressure plate assembly 231 to slide away from the movable cover 22, thereby completing the unlocking of the movable cover 22.

[0078] In summary, the gun-type handheld vacuum cleaner 100 of the present invention forms a mounting portion on the dust cup 21, and the dust cup cover has a movable cover 22 and a locking assembly 23 and is installed on the mounting portion. The pressure plate assembly 231 of the locking assembly 23 can slidably lock the movable cover 22 to prevent the dust outlet 211 from opening prematurely and causing the dust in the dust cup 21 to leak out, thereby improving the user experience.

[0079] By optimizing the sliding direction of the pressure plate assembly 221, making it parallel or perpendicular to the axis of the suction motor 11, the axis of the base station motor 230 of the dust collection station 200, and the axis of the separator 24, and forming an angle with the axis of the handle 3, the locking assembly 23 can unlock the movable cover 22 when the gun-type handheld vacuum cleaner 100 is placed in the integrated station 200, making it more convenient to use the gun-type handheld vacuum cleaner 100 and improving the user experience.
