The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0028] See also Figure 1-8The utility model provides a technical solution: a leak-proof milk powder can, comprising a can body 1, the interior of the can body 1 is set to be hollow, a circular groove is provided on the top of the can body 1, a round block 2 is provided in the circular groove, the interior of the round block 2 is set to be hollow, a measuring cylinder 3 is provided on the top of the round block 2, the measuring cylinder 3 is an existing structure, and no further description is given here, the measuring cylinder 3 rotates on the side close to the round block 2 to penetrate into the interior of the round block 2 and contacts with the bottom inner wall of the round block 2, a limiting mechanism is provided on the outer surface of the measuring cylinder 3, a square groove 15 is provided on the bottom surface of the round block 2, the left and right sides of the square groove 15 extend into the interior of the round block 2 respectively, two baffles 13 are provided inside the square groove 15, the adjacent sides of the two baffles 13 contact and fit, the opposite sides of the two baffles 13 extend into the square groove 15 respectively, and slide with the square groove 15, a section of the square groove 15 communicating with the interior of the round block 2 has a diameter smaller than the diameter of the measuring cylinder 3, two connecting grooves 14 are provided on the bottom inner wall of the round block 2, and the two connecting grooves 14 are respectively arranged on the left and right sides of the measuring cylinder 3 The baffle plate 13 is located in the square groove 15, and the top of the baffle plate 13 is fixedly connected with a fixed block 12. The top of the fixed block 12 passes through the connecting groove 14 and extends into the inside of the round block 2. The fixed block 12 is slidably connected with the connecting groove 14. The two fixed blocks 12 are located in the round block 2. The rear side surface is fixedly connected with a connecting rod 10. The side of the connecting rod 10 away from the fixed block 12 is fixedly connected with a displacement plate 7. The bottom inner wall of the round block 2 is provided with two T-slots 9, and the two T-slots 9 are respectively arranged on the two displacement plates 7. It is arranged on the same side, and a T-block 8 is slidably connected in the T-slot 9. The top of the T-block 8 passes through the T-slot 9 and is fixedly connected to the bottom surface of the displacement plate 7 on the same side. A pressing rod 5 is arranged between the two displacement plates 7. A sleeve plate 4 is fixedly sleeved on the outer surface of the pressing rod 5. A third spring 29 is fixedly connected between the bottom of the sleeve plate 4 and the inner wall of the round block 2. The top of the pressing rod 5 slides through the interior of the round block 2. A rotating plate 6 is rotatably connected to the left and right sides of the sleeve plate 4 and the displacement plate 7 on the same side.When it is necessary to take out a suitable amount of milk powder from the tank body 1, the tank body 1 is first turned over so that the side of the measuring cylinder 3 away from the tank body 1 faces downward, and then the pressing rod 5 is pressed to make the pressing rod 5 slide into the inside of the round block 2 and make the third spring 29 contract under the force. Since the pressing rod 5 slides through the inside of the round block 2 and a sleeve plate 4 is fixedly sleeved on the outer surface of the bottom, the pressing rod 5 will not shake during the movement and will not separate from the round block 2 after resetting. When the sleeve plate 4 moves with the pressing rod 5, it drives the two rotating plates 6 to make the two displacement plates 7 move horizontally in opposite directions. When the displacement plate 7 moves, it drives the T-block 8 on the same side to slide synchronously along the T-slot 9. Since the two relative cross bars of the T-block 8 are restricted by the two cross grooves in the T-slot 9, the displacement plate 7 is prevented from deviating and separating. When the displacement plates 7 make opposite horizontal movements, the connecting rod 10 between the two displacement plates 7 and the fixed blocks 12 causes the two fixed blocks 12 to make opposite horizontal movements synchronously when moving, so that the two baffles 13 make opposite movements synchronously and slide into the square groove 15, so that the interior of the measuring cylinder 3 inside the tank body 1 is communicated with each other, so that the milk powder inside the tank body 1 falls into the measuring cylinder 3 under the action of gravity. When the milk powder in the measuring cylinder 3 is collected to a suitable extent, the pressing rod 5 is released, so that the third spring 29 is restored, and the pressing rod 5 is pushed to slide out of the round block 2, so that the two baffles 13 are reset, and the adjacent sides of the two baffles 13 are fitted together, so as to cut off the communication between the interior of the tank body 1 and the interior of the measuring cylinder 3, and then the limiting mechanism is released, the measuring cylinder 3 is taken out for brewing, and then one side of the round block 2 on the tank body 1 is facing upward.
[0029] Furthermore, the limiting mechanism includes an annular block 16, which is movably mounted on the outside of the measuring cylinder 3, and the bottom of the annular block 16 is fixedly connected to the top surface of the round block 2. Two through grooves 17 are provided on the top of the annular block 16, and the two through grooves 17 are respectively arranged on the left and right sides of the measuring cylinder 3 and are arranged opposite to each other. Two semicircular annular grooves 18 are provided in the annular block 16, and the inner arc surfaces of the two semicircular annular grooves 18 are arranged oppositely.
[0030] Furthermore, the farthest sides of the two semicircular annular grooves 18 are respectively connected to the two through grooves 17, and the farthest sides of the two semicircular annular grooves 18 are slidably connected to the limiting blocks 19, and the opposite sides of the two limiting blocks 19 are respectively fixedly connected to the outer surface of the measuring cylinder 3. When the measuring cylinder 3 is facing downward away from the side of the tank body 1, the measuring cylinder 3 will not fall because the two limiting blocks 19 are limited by the two semicircular annular grooves 18. When the measuring cylinder 3 needs to be removed, the measuring cylinder 3 is first rotated to make the two limiting blocks 19 slide along the semicircular annular grooves 18 on the same side toward the through groove 17. When the limiting blocks 19 are aligned with the through groove 17 on the same side, the measuring cylinder 3 can be taken out.
[0031] Furthermore, a U-shaped handle 20 is fixedly connected to the top of the round block 2. The inside of the U-shaped handle 20 is hollow. A pressing block 21 is arranged on the side of the vertical rod of the U-shaped handle 20 close to the round block 2, and the other side of the pressing block 21 slides through the inside of the U-shaped handle 20.
[0032] Furthermore, a fixing rod 23 is fixedly connected to the inner wall of the top of the U-shaped handle 20. The other end of the fixing rod 23 slides through the inside of the pressing block 21. A second spring 22 is fixedly connected between the side of the pressing block 21 located inside the U-shaped handle 20 and the inner wall of the U-shaped handle 20. The second spring 22 is movably sleeved outside the fixing rod 23. When the pressing block 21 is pressed to move the pressing block 21 towards the inside of the U-shaped handle 20, the inside of the pressing block 21 slides along the outer surface of the fixing rod 23, and the second spring 22 is stressed and contracted. At the same time, the fixing rod 23 restricts the pressing block 21 to prevent the pressing block 21 from shaking.
[0033] Furthermore, L-shaped plates 24 are fixedly connected to both the left and right sides of a section of the pressing block 21 located inside the U-shaped handle 20. The vertical rods of the L-shaped plates 24 extend into the vertical rod of the U-shaped handle 20. Trapezoidal blocks 25 are fixedly connected to the bottoms of the two vertical rods of the L-shaped plates 24. The inclined sides of the trapezoidal blocks 25 slide through the inside of the round block 2.
[0034] Furthermore, two moving blocks 26 are arranged inside the round block 2. The two moving blocks 26 are respectively on the same side as the two trapezoidal blocks 25. Cross-sectionally L-shaped notches are formed on the opposite sides of the two moving blocks 26, and the horizontal surfaces of the L-shaped notches are inclined. The inclined surfaces of the moving blocks 26 are in contact and fit with the inclined surfaces of the trapezoidal blocks 25 on the same side. The vertical surfaces of the L-shaped notches are in contact with the surfaces of the trapezoidal blocks 25. The opposite sides of the two moving blocks 26 slide through the inside of the tank body 1. When the pressing block 21 moves upward, it drives the two L-shaped plates 24 to move synchronously, and the vertical rods of the two L-shaped plates 24 synchronously drive the trapezoidal blocks 25 to move upward, causing the two moving blocks 26 to move relatively, and the sides of the moving blocks 26 that penetrate into the inside of the tank body 1 slide into the inside of the round block 2, releasing the restriction on the round block 2, so that the round block 2 can be taken out. When the pressing block 21 is not pressed, the sides of the two moving blocks 26 that penetrate into the inside of the tank body 1 restrict the round block 2, so that the round block 2 does not shake or detach.
[0035] Furthermore, a second fixed block 27 is provided on the opposite side of the two moving blocks 26, the bottom of the second fixed block 27 is fixedly connected to the bottom inner wall of the round block 2, the internal sliding sleeve of the second fixed block 27 is provided with a second fixed rod 28, the opposite sides of the two second fixed rods 28 are fixedly connected to the surfaces of the two moving blocks 26 on the same side, and a tension spring 11 is fixedly connected between the second fixed block 27 and the moving block 26, and the tension spring 11 is movably sleeved on the outside of the second fixed rod 28. When the trapezoidal block 25 releases the restriction on the moving block 26, the tension spring 11 pulls the moving block 26 to move toward the inside of the circular block 2. When the trapezoidal block 25 restricts the moving block 26, the vertical surface of the L-shaped notch on the moving block 26 contacts the surface of the trapezoidal block 25, so that the tension spring 11 cannot pull the moving block 26 to move. Since the vertical surface of the L-shaped notch on the moving block 26 contacts the surface of the trapezoidal block 25, when the inclined surface of the trapezoidal block 25 pushes the moving block 26 to enter the tank body 1, the vertical surface of the L-shaped notch of the moving block 26 fits the surface of the trapezoidal block 25. Because the trapezoidal block 25 is restricted by the L-shaped plate 24, the stability of the moving block 26 is maintained, and the moving block 26 is prevented from resetting itself during use, causing the circular block 2 to fall into the tank body 1, thereby improving the stability of the device.
[0036] Working principle: When it is necessary to take out an appropriate amount of milk powder from the tank body 1, first turn the tank body 1 over so that the side of the measuring cylinder 3 away from the tank body 1 faces downwards. Then press the pressing rod 5 to make the pressing rod 5 slide into the inside of the round block 2, and make the third spring 29 contract under force. Since the pressing rod 5 slides through the inside of the round block 2 and a sleeve plate 4 is fixedly sleeved on the outer surface of the bottom, the pressing rod 5 will not shake during the movement and will not separate from the round block 2 after reset. When the sleeve plate 4 moves along with the pressing rod 5, it drives two rotating plates 6, so that two displacement plates 7 move horizontally in opposite directions. When the displacement plates 7 move, they drive the T-shaped blocks 8 on the same side to slide synchronously along the T-shaped grooves 9. Since the two opposite cross bars of the T-shaped blocks 8 are restricted by the two cross grooves in the T-shaped grooves 9, the displacement plates 7 are prevented from shifting and detaching. When the two displacement plates 7 move horizontally in opposite directions, through the connecting rod 10 between the fixed blocks 12, the two displacement plates 7 drive the two fixed blocks 12 to move horizontally in opposite directions synchronously when moving, so that the two baffle plates 13 move in opposite directions synchronously and slide into the square groove 15, making the inside of the measuring cylinder 3 in the tank body 1 communicate. Thus, the milk powder inside the tank body 1 drops into the measuring cylinder 3 under the action of gravity. When the milk powder in the measuring cylinder 3 is collected to an appropriate level, release the pressing rod 5, so that the third spring 29 resumes, pushing the pressing rod 5 to slide out of the round block 2, making the two baffle plates 13 reset, and the adjacent sides of the two baffle plates 13 fit together, cutting off the communication between the inside of the tank body 1 and the inside of the measuring cylinder 3. Then release the limiting mechanism, take out the measuring cylinder 3 for brewing work. Then make the side of the round block 2 on the tank body 1 face upwards. When the side of the measuring cylinder 3 away from the tank body 1 faces downwards, since the two limiting blocks 19 are restricted by the two semi-circular ring grooves 18, the measuring cylinder 3 will not drop. When it is necessary to remove the measuring cylinder 3, first rotate the measuring cylinder 3 so that the two limiting blocks 19 slide along the semi-circular ring grooves 18 on the same side towards the through groove 17. When the limiting blocks 19 are aligned with the through groove 17 on the same side, the measuring cylinder 3 can be taken out. When pressing the pressing block 21 to make the pressing block 21 move into the inside of the C-shaped handle 20, the inside of the pressing block 21 slides along the outer surface of the fixed rod 23, and makes the second spring 22 contract under force. At the same time, the fixed rod 23 restricts the pressing block 21 to prevent the pressing block 21 from shaking. When the pressing block 21 moves upwards, it drives two L-shaped plates 24 to move synchronously, and the vertical rods of the two L-shaped plates 24 drive the trapezoidal block 25 to move upwards synchronously, making the two moving blocks 26 move relatively, and the sides of the moving blocks 26 penetrating into the inside of the tank body 1 slide into the inside of the round block 2, releasing the restriction on the round block 2, so that the round block 2 can be taken out. When not pressing the pressing block 21, the sides of the two moving blocks 26 penetrating into the tank body 1 restrict the round block 2, so that the round block 2 will not shake and detach. When the trapezoidal block 25 releases the restriction on the moving block 26, the tension spring 11 pulls the moving block 26 to move into the inside of the round block 2. When the trapezoidal block 25 restricts the moving block 26, since the vertical surface of the L-shaped notch on the moving block 26 contacts the surface of the trapezoidal block 25, the tension spring 11 cannot pull the moving block 26 to move.Since the vertical surface of the L-shaped notch on the moving block 26 contacts the surface of the trapezoidal block 25, when the inclined surface of the trapezoidal block 25 pushes the moving block 26 into the tank body 1, the vertical surface of the L-shaped notch of the moving block 26 fits the surface of the trapezoidal block 25, and since the trapezoidal block 25 is restricted by the L-shaped plate 24, the stability of the moving block 26 is maintained, and the moving block 26 is prevented from resetting itself during use, causing the round block 2 to fall into the tank body 1, thereby improving the stability of the device.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
