  • the motion subassembly 200 is adapted to, when the box body 100 is unlocked, drive the box body 100 to pop out along the second direction M2 that is opposite to the first direction M1 to be opened.
  • the motion subassembly 200 includes a rack 210 connected to the box body 100, a gear 220 engaging with the rack 210, and an energy storage apparatus 230 connected to the gear 220.
  • the rack 210 is adapted to move with the box body 100 toward the first direction M1 when the box body 100 is pushed along the first direction M1, to drive the gear 220 to rotate along a first rotation direction (for example, counterclockwise), thereby driving the energy storage apparatus 230 to store energy.
  • a first rotation direction for example, counterclockwise
  • the rack 210 may be located above the box body 100 and provided with a clamping portion 211 extending toward a direction of the box body 100.
  • the box body 100 is provided with a receiving portion 110 fitted with the clamping portion 211.
  • the clamping portion 211 is clamped in the receiving portion 110 to join the rack 210 to the box body 100.
  • the energy storage apparatus 230 is adapted to release energy when the box body 100 is unlocked, to drive the gear 220 to rotate along a second rotation direction that is opposite to the first rotation direction (for example, clockwise), so that the rack 210 draws the box body 100 to pop out along the second direction M2 that is opposite to the first direction M1.
  • the energy storage apparatus 230 includes an energy storage component such as a tension spring and/or a coil spring, to store or release energy.
  • an energy storage component such as a tension spring and/or a coil spring, to store or release energy.
  • the energy storage apparatus 230 may further include a damping component, such as a mass block or a flywheel, connected to the energy storage component.
  • the damping component is adapted to move with the energy storage component and consume energy stored in the energy storage component, to speed down the gear 220 rotating along the second rotation direction and the rack 210 moving along the second direction M2, so that the box body 100 gently pops out along the second direction M2.
  • the detergent box assembly 10 further includes an outer shell 400 adapted to support the box body 100, the motion subassembly 200, and the lock subassembly 300.
  • the box body 100 is contained and supported in a space surrounded by the outer shell 400.
  • the outer shell 400 opens on a side thereof at a front end of the box body 100, so that the box body 100 can pop forward to be opened or be pushed backward to be closed relative to the outer shell 400.
  • the lock subassembly 300 is fixed on an outer side of the outer shell 400 and is located above the outer shell 400.
  • the outer shell 400 is provided with a hole corresponding to the lock slot 120 of the box body 100 and the bolt portion 333 of the lock pin 330.
  • the hole is adapted to enable the bolt portion 333 of the lock pin 330 to pass through to insert into the lock slot 120 of the box body 100.
  • the gear 220 and the energy storage apparatus 230 of the motion subassembly 200 are fixed in the outer shell 400.
  • the rack 210 of the motion subassembly 200 is at least partially contained in the outer shell 400.
  • the outer shell 400 further includes a supporting member 410 that is contained in the space surrounded by the outer shell 400 and that is located above the box body 100.
  • the supporting member 410 is adapted to enable the rack 210 to be movably supported on the supporting member 410.
  • the first contact portion 311 of the push rod 310 may further be movably connected to the motion subassembly 200 and be pushed by the motion subassembly 200 to move.
  • the first contact portion 311 of the push rod 310 may be movably connected to a back end of the rack 210 of the motion subassembly 200.
  • the first contact portion 311 of the push rod 310 is adapted to be abutted against and pushed by the rack 210 when the rack 210 moves with the box body 100 along the first direction M1.
  • the push rod 310 may also be directly pushed by the box body 100.
  • the first contact portion 311 of the push rod 310 may be movably connected to the box body 100.
  • the box body 100 comes into contact with the first contact portion 311 of the push rod 310 and pushes the push rod 310 to move along the first direction M1.
  • the box body 100 detaches from the first contact portion 311 of the push rod 310.
  • an embodiment of the present invention further provides a washing device 1.
  • the washing device 1 includes a washing tub, a water inlet pipe, and the detergent box assembly 10 provided in the embodiments of the present invention.
  • the washing tub is adapted to contain items to be washed.
  • the water inlet pipe is connected to the washing tub, and is adapted to guide water into the washing tub.
  • the detergent box assembly 10 is connected to the washing tub by means of the water inlet pipe.
  • the box body 100 of the detergent box assembly 10 is configured to contain detergent, and the detergent is adapted to enter the washing tub through the water inlet pipe.
