Through the cooperation between the above-mentioned components, the filtering of the refrigerant in the air conditioning system and the collection and discharge of impurities are realized, and the stable operation of the system is ensured. Among them, the liquid storage tank body 1 provides a storage space for the entire device; the upper end cover 2 and the lower end cover 3 play a sealing role; the collecting mechanism 4 is used to collect impurities; the stainless steel plug rod 5 facilitates the discharge of impurities; the filter assembly 6 filters impurities in the refrigerant; the transmission rod 7 cooperates with the transmission mechanism 8 to realize the shaking of the filter assembly 6; the floating ring 9 moves with the change of the liquid refrigerant height.

[0020] Furthermore, the collecting mechanism 4 includes a collecting frame 41, the bottom of which is provided with a plurality of through holes for welding with the stainless steel plug rod 5, and a knocking block is provided at the bottom of the stainless steel plug rod 5. The collecting frame 41 facilitates the collection of filtered impurities, and the stainless steel plug rod 5 cooperates with the knocking block to facilitate the removal of impurities when needed.

[0021] Furthermore, the transmission mechanism 8 includes a protective outer frame 81, which is connected to the inner side wall of the liquid storage tank body 1, and a first rotating rod 82 is rotatably provided on the inner top wall of the protective outer frame 81, and a guide wheel 83 is provided on the first rotating rod 82, and the guide wheel 83 is in conflict with the transmission rod 7, and a first groove wheel 84 is connected to one side of the guide wheel 83. The protective outer frame 81 plays a role in protecting the internal structure, and the first rotating rod 82, the guide wheel 83 and the first groove wheel 84 cooperate with the transmission rod 7 to realize the shaking of the filter assembly 6 and promote the discharge of impurities.

[0022] Furthermore, the transmission mechanism 8 also includes a second rotating rod 801, which is rotatably connected to the inner wall of the protective outer frame 81, and one end of the second rotating rod 801 is provided with a second groove wheel 802 that is transmission-connected to the first groove wheel 84, and the other end of the second rotating rod 801 is provided with a one-way gear 803. A plurality of grooves are opened on the outer wall of the one-way gear 803, and a plurality of telescopic components 88 are slidingly arranged in the grooves. A rack rod 804 is meshed on one side of the one-way gear 803, and the rack rod 804 is slidingly connected in the protective outer frame 81. The bottom end of the rack rod 804 is connected to the floating ring 9. The above components cooperate to realize the motion control of the rack rod 804 in different states, ensuring the stable operation of the equipment under different working conditions, wherein the second rotating rod 801 plays a transmission role; the second groove wheel 802 cooperates with the first groove wheel 84 to realize power transmission; the one-way gear 803 controls the unidirectional movement of the rack rod 804; the telescopic component 88 ensures the smoothness of the resetting of the rack rod 804.

[0023] Furthermore, the telescopic assembly 88 includes a telescopic tooth block 881, which is located in the groove, and both sides of the telescopic tooth block 881 are provided with limit slide bars 882 that slide with the side wall of the groove, and one side of the telescopic tooth block 881 is connected to a spring 883, and one side of the spring 883 is connected to the inner wall of the groove. The cooperation of the telescopic tooth block 881, the limit slide bar 882 and the spring 883 ensures that the rack rod 804 will not drive the one-way gear 803 to rotate or get stuck when resetting, thereby ensuring the smooth operation of the equipment.

[0024] Furthermore, two suction pipes 31 are inserted into the inner cavity of the liquid storage tank body 1, and the input ends of the two suction pipes 31 are both inserted into the liquid storage tank body 1. The two suction pipes 31 ensure that pure gaseous refrigerant can be stably output to the compressor, thereby improving the working efficiency of the system.

[0025] Furthermore, a limit block is provided on the side wall of the bottom end of the rack rod 804. The limit block prevents the rack rod 804 from excessive displacement during movement, thereby ensuring the stability of the device structure.

[0026] Furthermore, the filter assembly 6 includes a guide plate 61, which is slidably connected to the side wall of the liquid storage tank body 1, and the top of the guide plate 61 is arranged in an inclined shape, and a filter screen 62 is connected to the top of the guide plate 61. The inclined guide plate 61 and the filter screen 62 cooperate to effectively transport the filtered impurities to the collection frame 41, so as to avoid the clogging of impurities affecting the filtering effect and the smoothness of the refrigerant circulation.

[0027] Working principle: Overall process: the refrigerant in a gas-liquid mixed state coming out of the evaporator enters the liquid storage tank body 1 from the feed port at the top of the upper end cover 2. The liquid refrigerant falls to the bottom of the liquid storage tank body 1 due to its heavy weight, and the gaseous refrigerant remains in the top space of the liquid storage tank body 1. The pure gaseous refrigerant is output from the suction pipe 31 to the compressor, and then enters the air conditioning system circulation again after being sucked in and compressed; It should be noted that during the process, the filter assembly 6 in the liquid storage tank body 1 filters impurities in the refrigerant to prevent the impurities from entering the compressor and causing damage, and the filtered impurities are accumulated on the top of the filter screen 62; At the same time, the liquid refrigerant accumulation height continues to rise, and the linkage relationship generated is as follows: the floating ring 9 is pushed by the buoyancy, driving multiple rack rods 804 to move synchronously toward the top, and through the meshing relationship between the rack rod 804 and the one-way gear 803, the rack rod 804 pushes the one-way gear 803 to rotate when moving toward the top, and the rotation of the one-way gear 803 drives the second rotating rod 801 and the second groove wheel 802 to rotate synchronously, and the second groove wheel 802 drives the first groove wheel 84 to rotate through the toothed belt. Synchronously, the protective frame 81, the first rotating rod 82 and the guide wheel 83 rotate at the same time and push the transmission rod 7, and cooperate with the gravity. Figure 3 As shown, the transmission rod 7 and the filter assembly 6 will shake up and down, and the impurities accumulated on the top of the filter screen 62 will be shaken to the guide plate 61 through the shaking effect, and then the impurities on the top will be transported to the bottom of the collection frame 41 through the inclined setting of the guide plate 61 for accumulation. This structure can effectively avoid the blockage caused by the accumulation of impurities on the guide plate 61 after filtration, which affects the filtering effect and the smooth circulation of the refrigerant. Since the equipment has high requirements on sealing, the stainless steel plug rod 5 is welded to the bottom of the collection frame 41. During disassembly, the bottom of the stainless steel plug rod 5 is knocked by a knocking device to destroy the welding position. The stainless steel plug rod 5 can be taken out and the internal impurities can be poured out. After pouring out, the bottom of the collection frame 41 is welded and sealed by welding to improve the overall sealing effect.

[0028] It should be noted in this process that when the rack rod 804 is pushed toward the top, the one-way gear 803 can be driven to rotate. However, when the load of the air-conditioning system changes, the refrigerant stored in the accumulator can be added to the system to play a buffering role. When the system operates stably, the capacity of the liquid refrigerant at the bottom will decrease, and the height of the liquid refrigerant level will also decrease. At this time, the floating ring 9 and the rack rod 804 will move toward the bottom of the liquid storage tank body 1. During the process, due to the elastic expansion and contraction of the spring 883, when the rack rod 804 contacts the telescopic tooth block 881, the telescopic tooth block 881 contracts into the groove, avoiding the situation where the rack rod 804 drives the one-way gear 803 to rotate, or the one-way gear 803 jams the rack rod 804, thereby ensuring the smooth resetting of the rack rod 804.

[0029] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
