However, this operation method has exposed some obvious problems in actual application. The space in the mixing tank is limited. Pouring a large amount of raw materials at one time makes the distribution of the raw materials in the tank uneven. Some areas may have too much raw materials piled up, while some areas are relatively less. It is difficult to ensure that all raw materials are fully mixed in a short time. This may lead to uneven distribution of the components of the refrigerant, which greatly affects the preparation effect of the refrigerant. Therefore, those skilled in the art provide a proportioning device for mixing air-conditioning refrigerants to solve the problems raised in the above background technology.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model embodiment discloses a proportioning device for mixing refrigerants for air conditioners. Figure 1-3, a proportioning device for mixing air-conditioning refrigerants, comprising a mixing tank 1, wherein the upper and lower ends of the mixing tank 1 are respectively connected with a feed hopper 2 and a discharge pipe 3, an L-shaped plate 4 is arranged on the right side of the mixing tank 1, a mixing mechanism 5 is arranged between the mixing tank 1 and the L-shaped plate 4, and is used to stir and mix the raw materials in the mixing tank 1, a support plate 6 is arranged at the lower end of the inner part of the feed hopper 2, and a discharge mechanism 7 is arranged at the upper end of the support plate 6, and is used to discharge the raw materials in the feed hopper 2, a push mechanism 8 is arranged between the feed hopper 2 and the L-shaped plate 4, and is used to intermittently discharge the raw materials in the feed hopper 2 in cooperation with the discharge mechanism 7, and a linkage mechanism 9 is arranged between the mixing mechanism 5 and the push mechanism 8, and is used to link the mixing mechanism 5 and the push mechanism 8 to work synchronously;

[0028] Reference Figure 2 The mixing mechanism 5 includes a motor 501, a stirring rod 502 and a plurality of stirring blades 503. The motor 501 is arranged on one side of the L-shaped plate 4. The stirring rod 502 is rotatably arranged inside the mixing tank 1, one end of which passes through the interior of the mixing tank 1 and is rotatably connected to the inner side of the L-shaped plate 4. The output shaft of the motor 501 is connected to one end of the stirring rod 502, and the plurality of stirring blades 503 are all arranged on the outside of the stirring rod 502.

[0029] By adopting the above technical solution, when the raw materials enter the mixing tank 1, the motor 501 starts to work, and the stirring rod 502 can be driven to rotate through the operation of the motor 501. The rotation of the stirring rod 502 drives the stirring blade 503 to rotate, so that the raw materials in the mixing tank 1 can be stirred and mixed.

[0030] Reference Figure 3 The discharging mechanism 7 includes a connecting sleeve 701, a T-shaped rod 702, a conical baffle 703 and a spring 704. The connecting sleeve 701 is arranged at the upper end of the supporting plate 6. The T-shaped rod 702 is slidably arranged inside the connecting sleeve 701, and the top of the T-shaped rod 702 passes through the interior of the connecting sleeve 701. The conical baffle 703 is arranged at the top of the T-shaped rod 702. The outer side of the conical baffle 703 is in contact with the inner wall of the feed hopper 2. The spring 704 is sleeved on the outer side of the T-shaped rod 702. The two ends of the spring 704 are respectively connected to the T-shaped rod 702 and the inner wall of the connecting sleeve 701; the pushing mechanism 8 includes a rotating rod 801 and a cam 802. The rotating rod 801 is rotatably arranged on the inner upper end of the L-shaped plate 4, and its end away from the L-shaped plate 4 passes through the interior of the feed hopper 2 and is provided with a cam 802.

[0031] By adopting the above technical solution, the rotation of the rotating rod 801 can drive the cam 802 to rotate. The rotation of the cam 802 squeezes the conical baffle 703 to move the conical baffle 703 upward. The upward movement of the conical baffle 703 will compress the spring 704 through the T-shaped rod 702. At this time, the raw materials in the feed hopper 2 can be discharged through the gap between the conical baffle 703 and the inner wall of the feed hopper 2. When the cam 802 is no longer in contact with the conical baffle 703, the spring 704 resets the conical baffle 703 to continue to block the raw materials in the feed hopper 2, so that the proportioned raw materials can intermittently fall into the mixing tank 1.

[0032] Reference Figure 2 The linkage mechanism 9 includes two pulleys 901 and a belt 902. The two pulleys 901 are respectively installed on the outside of the rotating rod 801 and the stirring rod 502. The belt 902 is arranged between the two pulleys 901 to drive the rotating rod 801 and the motor 501 to rotate synchronously.

[0033] By adopting the above technical solution, when the stirring rod 502 rotates, the cooperation of the pulley 901 and the belt 902 can drive the rotating rod 801 to rotate synchronously, so that the raw materials can be discharged and mixed synchronously.

[0034] Reference Figure 1 and Figure 2 A valve is installed on the discharge pipe 3 to control the discharge of raw materials through the discharge pipe 3.

[0035] By adopting the above technical solution, when the raw materials are mixed, the valve on the discharge pipe 3 is opened, so that the raw materials can be discharged through the discharge pipe 3.

[0036] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. When preparing the refrigerant, the staff pours the proportioned raw materials into the feed hopper 2, and then the motor 501 works to drive the stirring rod 502 to rotate. The stirring rod 502 rotates to drive the rotating rod 801 to rotate synchronously with the pulley 901 and the belt 902. The rotating rod 801 rotates to drive the cam 802 to rotate. The cam 802 rotates to squeeze the conical baffle 703 so that the conical baffle 703 moves up. The upward movement of the conical baffle 703 The T-shaped rod 702 will compress the spring 704. At this time, the raw materials in the feed hopper 2 can be discharged through the gap between the conical baffle 703 and the inner wall of the feed hopper 2, and then the raw materials fall into the interior of the mixing tank 1 and can be stirred and mixed by the stirring blades 503. When the cam 802 is no longer in contact with the conical baffle 703, the conical baffle 703 is reset by the spring 704 to continue to block the raw materials in the feed hopper 2, so that the proportioned raw materials can intermittently fall into the interior of the mixing tank 1, thereby making the mixing effect of the raw materials better and more uniform.

[0037] When the utility model is in use, by allowing the raw materials with good proportions to intermittently enter the interior of the mixing tank 1, the mixing effect of the raw materials is better and more uniform, thereby ensuring the preparation effect of the refrigerant.
