[0038] Please refer to Figure 1-Figure 6 , this embodiment provides a refrigeration unit air duct assembly 100, the refrigeration unit air duct assembly 100 includes a mounting frame 110, a movable filter 120, a driving motor 130 and a cleaning brush 140;

[0039] The mounting frame 110 is provided with an air inlet duct 111 and an air exhaust duct 112; the movable filter 120 is rotatably connected to the mounting frame 110, and along its rotation axis, the projections of the air inlet duct 111 and the air exhaust duct 112 are both located within the movable filter 120; the driving motor 130 is used to drive the movable filter 120 to rotate relative to the mounting frame 110; the cleaning brush 140 is fixedly connected to the mounting frame 110 and contacts the movable filter 120 to clean the movable filter 120 when the movable filter 120 rotates.

[0040] Please refer to Figure 1-Figure 6 The working principle of the refrigeration unit air duct assembly 100 is:

[0041] The refrigeration unit air duct assembly 100 is installed at the air inlet of the refrigeration unit, and its purpose is to intercept debris during the air intake process to prevent the debris from entering the air duct and affecting the normal operation of the equipment. During the interception process, the debris is filtered and intercepted by the movable filter 120;

[0042] Since the movable filter 120 is rotatably connected to the mounting frame 110, and the projections of the air inlet duct 111 and the air outlet duct 112 are both located in the movable filter 120 along the rotation axis thereof; the driving motor 130 is used to drive the movable filter 120 to rotate relative to the mounting frame 110; the cleaning brush 140 is fixedly connected to the mounting frame 110 and contacts the movable filter 120 to clean the movable filter 120 when the movable filter 120 rotates; thus, the movable filter 120 can rotate relative to the air duct to The relative position of the filter 120 relative to the air duct can be adjusted. In this embodiment, the air duct includes the air inlet duct 111 and the air outlet duct 112. That is, under the driving action of the driving motor 130, the movable filter 120 will rotate relative to the air inlet duct 111 and the air outlet duct 112, so that the movable filter 120 will change its position relative to the air inlet duct 111 and the air outlet duct 112 through the change of position, and then the accumulation on the movable filter 120 can be avoided by the movement of the movable filter 120.

[0043] Moreover, during this process, since the cleaning brush 140 is fixedly connected to the mounting frame 110, as the movable filter 120 rotates, the movable filter 120 will continuously pass through the cleaning brush 140, and then the movable filter 120 and the cleaning brush 140 can form a relative movement through the rotation of the movable filter 120, so that the cleaning brush 140 can clean the movable filter 120 through the contact between the cleaning brush 140 and the movable filter 120, thereby preventing debris from accumulating on the movable filter 120 and causing the movable filter 120 to be blocked;

[0044] In summary, the refrigeration unit air duct assembly 100 is used in a refrigeration vending machine 200. During the air intake process, the filter in the air duct can be cleaned to avoid the filter being blocked, thereby maintaining normal air intake. This can prevent the refrigeration unit from experiencing abnormal heat dissipation or refrigeration functions, thereby ensuring the long-term normal operation of the refrigeration unit.

[0045] For further information, please refer to Figure 1-Figure 6 In this embodiment, when configuring the mounting frame 110, the mounting frame 110 is configured with a circular air duct 113 and a partition 114. The partition 114 is connected to the mounting frame 110 and divides the circular air duct 113 into a semicircular air inlet duct 111 and a semicircular air outlet duct 112. Such a configuration can be adapted to the circular movable filter 120, and the radius of the circular air duct 113 is smaller than the radius of the circular movable filter 120. On the basis that the circular air duct 113 is directly opposite to the movable filter 120, the semicircular air inlet duct 111 and the semicircular air outlet duct 112 are kept directly opposite to the movable filter 120.

[0046] In order to facilitate the installation of the movable filter 120 and the cleaning brush 140, the refrigeration unit air duct assembly further includes a connecting frame 150, which is connected to the mounting frame 110, spans the circular air duct 113, and is directly opposite to the partition 114; the movable filter 120 is rotatably connected to the connecting frame 150, and the cleaning brush 140 is connected to the connecting frame 150. Such a setting method can facilitate the installation of the movable filter 120 and the cleaning brush 140, and during the setting process, the cleaning brush 140 is located between the movable filter 120 and the connecting frame 150, so that the movable filter 120 can be cleaned as the movable filter 120 rotates. Moreover, in order to prevent the connecting frame 150 and the cleaning brush 140 from affecting the air intake or exhaust, when setting the connecting frame 150, the part of the connecting frame 150 that spans the circular air duct 113 is a strip-shaped piece, and the cleaning brush 140 is a strip-shaped brush connected to the connecting frame 150, and it is parallel to the partition 114. In this way, the partition 114, the connecting frame 150 and the cleaning brush 140 are in a parallel state, thereby avoiding affecting the ventilation efficiency.

[0047] Please note that, please refer to Figure 1-Figure 6 In the present embodiment, an example is taken inlet duct 111 and exhaust duct 112 to illustrate. Based on this, while the cleaning brush 140 is cleaning the movable filter 120, the airflow discharged from the exhaust duct 112 can also purge the movable filter 120, thereby blowing and cleaning the movable filter 120. Such a setting can be performed simultaneously with the cleaning effect of the cleaning brush 140, thereby effectively preventing the movable filter 120 from being blocked.

[0048] Based on the above refrigeration unit air duct assembly 100, please refer to Figure 1-Figure 9 This embodiment also provides a refrigeration vending machine 200, which includes a cabinet 210, a refrigeration assembly 220 and the above-mentioned refrigeration unit air duct assembly 100;

[0049] The cabinet 210 is provided with a refrigeration chamber 211, an air guide cavity 212 and an installation cavity 213; the refrigeration assembly 220 is installed in the refrigeration chamber 211, and the air guide cavity 212 is connected with the refrigeration chamber 211 and the installation cavity 213; the refrigeration unit air duct assembly 100 is installed in the installation cavity 213;

[0050] Among them, a wind shield plate 214 is arranged in the air guide cavity 212 to separate it into an air inlet channel 215 and an air exhaust channel 216 . The air inlet channel 215 is connected to the air inlet duct 111 , and the air exhaust channel 216 is connected to the air exhaust channel 216 .

[0051] Please refer to Figure 1-Figure 9 The cabinet 210 of the refrigeration vending machine 200 is provided with a refrigeration chamber 211, an air guide cavity 212 and an installation cavity 213, wherein the refrigeration chamber 211, the air guide cavity 212 and the installation cavity 213 are connected in sequence, and the installation cavity 213 is located on the outside to guide air to the air guide cavity 212 and the refrigeration chamber 211, thereby, the refrigeration unit air duct assembly 100 can be installed in the installation cavity 213, and in the process of guiding air to the air guide cavity 212 and the refrigeration chamber 211, through the corresponding cleaning brush 140 and the structural setting of the movable filter 120, it is possible to avoid clogging of the movable filter 120, thereby maintaining a stable ventilation efficiency, thereby ensuring the normal operation of the quality components located in the refrigeration chamber 211.

[0052] When configuring the air inlet channel 215 and the air exhaust channel 216, in order to enable the wind discharged from the exhaust channel 216 to sweep the active filter 120 and avoid the accumulation of debris, the air inlet channel 215 is located above the exhaust channel 216, so as to reduce the debris on the active filter 120 in this way.

[0053] Furthermore, when configuring the wind shield 214 between the air inlet channel 215 and the exhaust channel 216, the connecting frame 150 is arranged to be directly opposite to the wind shield 214 between the air inlet channel 215 and the exhaust channel 216. Therefore, the wind shield 214, the partition 114, the connecting frame 150 and the cleaning brush 140 are all in a parallel state, thereby reducing the impact on the ventilation area to maintain the ventilation efficiency.

[0054] Please refer to Figure 1-Figure 9On the basis of the above structure, in order to improve the efficiency of air intake and exhaust, and to rotate the active filter 120 to blow the exhaust passage 216, an air intake fan 230 is provided in the air intake passage 215, and an exhaust fan 240 is provided in the exhaust passage 216. In addition, in order to prevent large debris from being introduced into the air passage, a protective net 250 is provided at one end of the installation cavity 213 that is connected to the outside, so that the protective net 250 can be used for primary interception, and the active filter 120 can be used for secondary interception, thereby improving the smoothness of the air passage.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
