DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a sealing device for a dispensing machine. Figure 1 The cabinet 1 of the dispensing machine includes a door frame 11 and a cabinet door 12. The cabinet 1 is provided with a receiving cavity 13. The door frame 11 has a connecting hole connecting the receiving cavity 13 with the outside, and the cabinet door 12 is used to close the connecting hole. A handle 5 is provided on the outside of the cabinet door 12 to facilitate the staff to open and close the cabinet door 12. The sealing device of the present application is used to improve the sealing effect of the door frame 11 and the cabinet door 12. It is worth noting that in this embodiment, the sizes of the door frame 11 and the cabinet door 12 are exaggerated, and the sizes of the door frame 11 and the cabinet door 12 are enlarged.

[0036] Reference Figure 1 A sealing device for a medicine dispensing machine includes an electromagnet 2 and a sealing ring 3. The door frame 11 includes a first side edge 111 and a second side edge 112 which are arranged opposite to each other. The first side edge 111 is hinged to the cabinet door 12, and the second side edge 112 is provided with a receiving groove 1121.

[0037] Reference Figure 1 and Figure 2 The electromagnet 2 is fixed in the receiving groove 1121, and the electromagnet 2 is flush with the door frame 11. The number of receiving grooves 1121 and electromagnets 2 corresponds one to one, and the number of electromagnets 2 can be designed to be multiple; in this embodiment, the number of electromagnets 2 is set to one.

[0038] Reference Figure 1 and Figure 3The cabinet door 12 includes a metal frame 121 and a cabinet door plate 122. The metal frame 121 is fixedly connected to the cabinet door plate 122. One side of the metal frame 121 is hinged to the door frame 11, and the metal frame 121 is arranged opposite to the door frame 11. The sealing ring 3 is fixedly arranged between the door frame 11 and the metal frame 121. In this embodiment, the sealing ring 3 is fixedly connected to the metal frame 121, and the sealing ring 3 abuts against the door frame 11. In other embodiments, one side of the sealing ring 3 can also be fixedly connected to the door frame 11, and the other side of the sealing ring 3 abuts against the door frame 11. The sealing ring 3 can be made of materials such as rubber and silicone.

[0039] The implementation principle of a sealing device for a dispensing machine in the embodiment of the present application is as follows:

[0040] When the staff closes the cabinet door 12, the electromagnet 2 on the door frame 11 is energized, and the current in the electromagnet 2 is gradually increased; thereby, the force of the electromagnet 2 on the metal frame 121 is controlled by controlling the current in the electromagnet 2. Therefore, under the suction force of the electromagnet 2 on the metal frame 121, the metal frame 121 and the door frame 11 squeeze the sealing ring 3 to deform, thereby reducing the gap between the sealing ring 3 and the door frame 11 or the cabinet door 12, and improving the sealing effect between the door frame 11 and the cabinet door 12.

[0041] Example 2

[0042] The difference between this embodiment 2 and embodiment 2 is that:

[0043] The sealing device further comprises a magnetic strip 4 , which is arranged inside the sealing ring 3 .

[0044] Reference Figure 4 and Figure 5 The sealing ring 3 includes a first component 31, a second component 32 and a third component 33, which are integrally formed. The first component 31 and the second component 32 are arranged along the direction from the metal frame 121 to the door frame 11, the first component 31 is fixedly connected to the metal frame 121, and the first component 31 is provided with a first cavity 311; therefore, when the door frame 11 and the metal frame 121 squeeze the sealing ring 3, the first cavity 311 is conducive to the deformation of the sealing ring 3, increases the area where the sealing ring 3 fits the door frame 11, and improves the sealing effect between the door frame 11 and the metal frame 121.

[0045] The second component 32 is used to abut against the door frame 11, and the side of the second component 32 close to the door frame 11 is a straight abutting surface 322, and the straight abutting surface 322 fits with the door frame 11, thereby improving the sealing effect of the sealing ring 3 on the door frame 11. The second component 32 is provided with a second cavity 321, and the magnetic strip 4 is arranged in the second cavity 321. In this embodiment, the door frame 11 is made of metal, and the magnetic strip 4 attracts the door frame 11 to force the straight abutting surface 322 to fit with the door frame 11. The magnetic strip 4 and the door frame 11 attract each other, thereby forcing the straight abutting surface 322 to fit closely with the door frame 11, thereby improving the sealing effect between the cabinet door 12 and the door frame 11.

[0046] At the same time, an avoidance gap is provided between the outer periphery of the first component 31 and the outer periphery of the second component 32 , and the width of the first component 31 is greater than the width of the second component 32 ; thus, deformation of the first component 31 and the second component 32 is facilitated.

[0047] There are two third components 33 of the sealing ring 3, and the two third components 33 are arranged on both sides of the first component 31 and the second component 32. One end of the third component 33 is fixedly connected to the metal frame 121, and the other end of the third component 33 abuts against the door frame 11. The distance from the third component 33 to the metal frame 121 is greater than the distance from the second component 32 to the metal frame 121. In this embodiment, the surface of the third component 33 abutting against the door frame 11 is an arc surface 331, and the opening direction of the arc surface 331 is set toward the metal frame 121.

[0048] The implementation principle of a sealing device for a dispensing machine in the embodiment of the present application is as follows:

[0049] Reference Figures 4 to 6 , so that when the cabinet door 12 and the door frame 11 approach each other, the cabinet door 12 and the door frame 11 first squeeze the third component 33, so as to force the third component 33 to be compressed and deformed to be located on the same plane as the straight abutting surface 322. Then, the straight abutting surface 322 fits with the door frame 11, and the sealing ring 3 has a sealing effect. Finally, when the current in the electromagnet 2 increases and the container cavity of the cabinet body 1 is evacuated, the door frame 11 and the cabinet door 12 further squeeze the sealing ring 3 to further improve the sealing effect of the sealing ring 3.

[0050] When the staff needs to open the cabinet door 12, the power supply of the electromagnet 2 is turned off, and air is introduced into the accommodating chamber 13 to keep the air pressure inside and outside the cabinet 1 consistent. At this time, the third component 33 of the sealing ring 3 tends to return to its original state, and the third component 33 can lift the cabinet door 12. Therefore, when the staff opens the cabinet door 12, it is convenient for air to enter the gap between the sealing ring 3 and the door frame 11, so that it is convenient for the staff to open the cabinet door 12. The third invisible arc surface 331 is more conducive to the penetration of external air into the joint between the sealing ring 3 and the door frame 11.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
