[0034] Example: Refer to Figure 1-6 As shown, this utility model discloses a first embodiment of a base station with a three-way valve, which includes a base station body 1000 having a base station vacuum chamber 1020 and a base station motor 1060, a base station bracket 1200 for docking with a vacuum cleaner, a connecting pipe 1400 connecting the interior of the base station body 1000 and the interior of the base station bracket 1200, and a three-way valve 2000 disposed in the base station body 1000.

[0035] The base station body 1000 is roughly rectangular, with the base station vacuum chamber 1020 located above the base station motor 1060. To further collect dust, the base station body 1000 also includes a dust bag 1040 located within the base station vacuum chamber 1020 to collect dust from a vacuum cleaner. The air inlet of the dust bag 1040 is connected to one end of a three-way valve 2000. The base station body 1000 further includes an adjustment display unit 1100, an automatic mode unit 1160, and a manual mode unit 1180. The adjustment display unit 1100 includes a decrement adjustment knob 1120 and an increment adjustment knob 1140. A dust drain port 1220 is provided inside the base station bracket 1200.

[0036] The three-way valve 2000 includes a first valve connector 2200 having a connecting chamber 2204, a second valve connector 2400 connected to one end of the first valve connector 2200 and having a valve chamber 2420, and a valve core 2600 located at least partially within the valve chamber 2420 and capable of switching air paths. The second valve connector 2400 is connected to the interior of the connecting pipe 1400. The valve core 2600 includes an inner valve core chamber 2620 and an outer rotary knob 2640 for easy rotation by the user. One end of the valve core chamber 2620 is connected to either the interior of the first valve connector 2200 or the interior of the second valve connector 2400, while the other end of the valve core chamber 2620 is located upstream of the base station vacuum chamber 1020 and connected to the air inlet of the dust bag 1040. The second valve connector 2400 also includes a microswitch 2460 located on one side of the valve cavity 2420. The valve core 2600 includes an outer edge of the valve core located outside the rotary knob 2640, a first contact 2604 located on the outer edge of the valve core and capable of actuating the microswitch 2460, and a second contact 2608 located on the outer edge of the valve core and circumferentially spaced from the first contact 2604, also capable of actuating the microswitch 2460. The circumferential angle between the first contact 2604 and the second contact 2608 is greater than or equal to 90 degrees. The central extension directions of the first valve connector 2200 and the second valve connector 2400 are perpendicular. The central extension direction of the second valve connector 2400 is on the same straight line as the central extension direction of the connecting pipe 1400.

[0037] like Figure 7-13 As shown, based on the first embodiment, this utility model further discloses a second embodiment of a system, which includes a vacuum cleaner 100, a vacuuming hose 200 connected to the vacuum cleaner 100 at one end, a vacuuming brush 300 connected to the other end of the vacuuming hose 200, a grooming attachment 3000, a flexible tube 3200 connected to the grooming attachment 3000 at one end and to the first valve hose 2200 at the other end, and a base station docked with the vacuum cleaner 100, wherein the base station is the base station in the first embodiment.

[0038] The center direction of the vacuum tube 200 is parallel to the center direction of the connecting tube 1400, and the vacuum brush 300 is arranged adjacent to one side of the base station body 1000.

[0039] The valve core 2600 includes an inner valve core cavity 2620 and an outer rotary knob 2640 for easy rotation by the user. One end of the valve core cavity 2620 is connected to the inside of either the first valve connector 2200 or the second valve connector 2400, while the other end of the valve core cavity 2620 is located upstream of the base station vacuum chamber 1020.

[0040] The second valve connector 2400 also includes a micro switch 2460 located on one side of the valve cavity 2420, wherein the valve core 2600 includes an outer edge of the valve core located outside the rotary knob 2640, a first contact 2604 located on the outer edge of the valve core and capable of causing the micro switch 2460 to operate, and a second contact 2608 located on the outer edge of the valve core and circumferentially spaced from the first contact 2604 and capable of causing the micro switch 2460 to operate.

[0041] When in operation, when the rotary knob 2640 is aligned with the horizontal mark, it is in pet vacuum working mode. The second contact 2608 causes the micro switch 2460 to operate, the base station motor 1060 starts running, and the adjustment display unit 1100 lights up, which is divided into three levels: high, medium and low, for easy user adjustment. Then, the user can groom the pet through the grooming accessory 3000. The pet's hair or dander enters through the flexible tube 3200 and the inlet end 2220 of the first valve connecting pipe 2200, and enters the three-way valve 2000 through the connecting pipe cavity 2204. Since the first valve connecting pipe 2200 is connected to the valve core cavity 2620 at this time, the pet's hair or dander directly enters the dust bag 1040 under the action of the vacuum airflow. When the rotary knob 2640 is turned to the vertical mark, the first contact 2604 actuates the micro switch 2460, and the base station motor 1060 starts running, entering the dust collection mode. The user can select different dust collection modes through the automatic mode unit 1160 or the manual mode unit 1180. In this mode, the second valve connector 2400 is connected to the valve core cavity 2620. Dust inside the vacuum cleaner 100, especially dust collected in the dust cup, moves downwards from the dust outlet 1220 under the influence of gravity and vacuum negative pressure, entering the inlet 2440 of the second valve connector 2400 through the internal channel of the connecting pipe 1400. Since the second valve connector 2400 is connected to the valve core cavity 2620, dust from the vacuum cleaner 100 directly enters the dust bag 1040. This completes the switching between different modes.

[0042] This utility model, through its three-way valve structure, not only facilitates the collection of dust inside the vacuum cleaner from the base station, but also facilitates the collection of household hair.

[0043] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
