Description

Technical Field

[0001] The invention relates to the technical field of automatic vending, and in particular to a wall-breaking cup sealing device. Background Art

[0002] Vending machines are currently mainly aimed at finished products, such as beverages, snacks, medicines, etc., but vending machines for beverages made on site are still rare. For example, beverages made on site that are a mixture of one or more of whole grains, oats, fruits, dairy products, and dried fruits. In the specific process of preparing these beverages, it is necessary to complete them quickly on site without human operation, which requires a sealed cup environment for wall breaking and / or stirring to prevent liquid from overflowing from the cup mouth during the wall breaking process. After the wall breaking and / or stirring are completed, there is a certain pressure during the sealing. If the seal is removed rashly without external interference, it is likely to cause the cup to overturn, and it is impossible to smoothly achieve wall breaking and / or stirring without human intervention. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a wall-breaking cup sealing device, which can achieve both sealing and smooth unsealing through the mutual cooperation of the improved cup body and the sealing assembly. The specific technical solution is as follows.

[0004] A wall-breaking cup sealing device comprises: a wall-breaking cup, wherein an outward annular protrusion is arranged on the top of the wall-breaking cup; a sealing cover, wherein an annular sealing ring is arranged on the bottom of the outer edge of the sealing cover, and the annular sealing ring is in sealing contact with the inner edge of the top of the wall-breaking cup; a cup pressing ring, wherein an outward annular protrusion is arranged on the bottom of the cup pressing ring, and the cup pressing ring is sleeved on the periphery of the sealing cover and in contact with the annular protrusion of the cup pressing ring just presses the annular protrusion of the wall-breaking cup; a fixing plate, wherein the fixing plate is fixedly connected to the sealing cover by a screw, and the fixing plate is connected to the cup pressing ring by a guide column, and a spring is arranged on the periphery of the guide column.

[0005] Furthermore, the fixing plate and the sealing cover are provided in the middle with spaces required for the wall breaking rod and the wall breaking knife to pass through.

[0006] Furthermore, the cross-section of the wall-breaking cup is an inverted trapezoid, and the annular sealing ring includes a first sealing ring and a second sealing ring, and the first sealing ring and the second sealing ring are both arranged in an annular groove at the bottom of the edge of the sealing cover.

[0007] Furthermore, a reinforcing protrusion is arranged inside the wall-breaking cup.

[0008] Furthermore, the number of reinforcement protrusions arranged inside the wall-breaking cup is 2-5.

[0009] Furthermore, the guide column is inserted from the bottom of the cup pressing ring, and after the spring is sleeved, it is inserted into the fixing plate, and the guide column and the fixing plate are connected by screws.

[0010] Furthermore, when sealing begins, the spring is in normal state, the bottom of the cup pressing ring is flush with the bottom of the sealing cover, and when the wall-breaking cup sealing device moves downward as a whole, the annular protrusion of the cup pressing ring first presses the annular protrusion of the wall-breaking cup, and the sealing cover continues to move downward. The spring is compressed, so that the annular seal is in close contact with the wall-breaking cup to achieve sealing.

[0019] The technical solution of the present invention will be described in detail below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application. Example 1

[0020] The present invention aims to provide a wall-breaking cup sealing device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes: a wall-breaking cup 1, the top of which is provided with an outward annular protrusion 2; a sealing cover 3, the bottom of the outer edge of the sealing cover 3 is provided with an annular sealing ring, and the annular sealing ring is in sealing contact with the inner edge of the top of the wall-breaking cup 1; a cup-pressing ring 4, the bottom of which is provided with an outward annular protrusion 41, the cup-pressing ring 4 is sleeved on the periphery of the sealing cover 3 and in contact, and the annular protrusion 41 of the cup-pressing ring 4 just presses the annular protrusion 2 of the wall-breaking cup 1; a fixing plate 8, the fixing plate 8 is fixedly connected to the sealing cover 3 by a screw 9, the fixing plate 8 is connected to the cup-pressing ring 4 by a guide column, and a spring is arranged around the guide column.

[0021] By arranging an annular sealing ring at the bottom of the outer edge of the sealing cover 3, the annular sealing ring is in sealing contact with the inner edge of the top of the broken wall cup 1, so that sealing is achieved under a certain pressure; at the same time, a cup pressing ring 4 and an annular bulge 41 of the cup pressing ring are also provided, and the annular bulge 41 of the cup pressing ring just presses the annular bulge 2 of the broken wall cup, so that the broken wall cup 1 is always pressed firmly; when the seal is released, the sealing cover 3 moves upward, and the cup pressing ring 4 is still pressed by the spring 6. When the bottom of the cup pressing ring 4 is flush with the bottom of the sealing cover 3, the annular seal is separated from the close contact with the broken wall cup 1, and the seal is released, so that the annular bulge 41 of the cup pressing ring 4 leaves the annular bulge 2 of the broken wall cup 1 only when the seal is completely released, so that the broken wall cup 1 is always pressed firmly during the sealing release process.

[0022] As a preferred embodiment, Figure 1 As shown, the fixing plate 8 and the sealing cover 3 are provided with spaces required for the wall breaking rod and the wall breaking knife to pass through in the middle.

[0023] This sealing device is used for on-site preparation of beverages in vending machines, such as a mixture of one or more of cereals, oats, fruits, dairy products, and dried fruits. A wall-breaking knife or a stirring mechanism needs to pass through the sealing device of this application. For this purpose, the fixed plate 8 and the middle part of the sealing cover 3 are provided with the space required for the wall-breaking rod and the wall-breaking knife to pass through.

[0024] As a preferred embodiment, Figure 1 As shown, the cross-section of the wall-breaking cup 1 is an inverted trapezoid, and the annular sealing ring includes a first sealing ring 31 and a second sealing ring 32. The first sealing ring 31 and the second sealing ring 32 are both arranged in the annular groove at the bottom of the edge of the sealing cover.

[0025] In this embodiment, because the cross-section of the wall-breaking cup 1 is an inverted trapezoid, after the sealing cover 3 enters the wall-breaking cup 1, the further downward it goes, the greater the pressure on the cup body and the better the sealing. This will also make it difficult to release the seal when there is no external force interference, such as the annular protrusion 41 in the present application pressing the annular protrusion 2. At the same time, it may also cause the wall-breaking cup 1 to overturn. For this reason, we provide two annular sealing rings so that the sealing cover 3 can achieve good sealing by entering the wall-breaking cup 1 at a shorter distance, making it easier to release the seal.

[0026] As a preferred embodiment, Figure 1 As shown, a reinforcing protrusion 11 is arranged inside the wall-breaking cup 1.

[0027] Breaking the wall usually requires the rotation speed of the wall breaking knife to be above 25000r / min. In order to achieve the effect of quickly making drinks on site, short time is one of the key factors. In order to speed up the wall breaking, a reinforcing protrusion is provided in the wall breaking cup 1, which helps the drink to rotate in a circle and tumble up and down in the wall breaking cup 1, which is beneficial to improve the cutting efficiency of the wall breaking knife and shorten the time.

[0028] As a preferred embodiment, Figure 1 As shown, the number of the reinforcing protrusions 11 arranged inside the wall-breaking cup 1 is 2-5.

[0029] Breaking the wall usually requires the rotation speed of the wall breaking knife to be above 25000r / min. In order to achieve the effect of quickly making drinks on site, short time is one of the key factors. In order to speed up the wall breaking, a reinforcing protrusion is provided in the wall breaking cup 1, which helps the drink to rotate in a circle and tumble up and down in the wall breaking cup 1, which is beneficial to improve the cutting efficiency of the wall breaking knife and shorten the time.

[0030] As a preferred embodiment, Figure 4 As shown, the guide column 5 is inserted from the bottom of the cup pressing ring 4, and after the spring 6 is sleeved, it is inserted into the fixing plate 8, and the guide column 5 and the fixing plate 8 are connected by screws 7.

[0031] The main function of this embodiment is to set the sealing cover 3 and the cup pressing ring 4 as a whole through the guide column 5, the spring 6 and the fixing plate 8, and at the same time enable the sealing cover 3 and the cup pressing ring 4 to move relative to each other, so that when sealing, the bottom of the sealing cover 3 is lower than the bottom of the cup pressing ring 4 to achieve sealing, and when releasing the seal, the bottom of the sealing cover 3 is flush with the bottom of the cup pressing ring 4 to achieve releasing the seal, and the whole process ensures the firmness of the wall-breaking cup 1.

[0032] As a preferred embodiment, when sealing begins, the spring 6 is in a normal state, the bottom of the cup pressing ring 4 is flush with the bottom of the sealing cover 3, and when the wall-breaking cup sealing device moves downward as a whole, the annular protrusion 41 of the cup pressing ring first presses the annular protrusion 2 of the wall-breaking cup, and the sealing cover 3 continues to move downward, and the spring 6 is compressed, so that the annular seal is in close contact with the wall-breaking cup 1 to achieve sealing. Figure 1 Status shown.

[0033] As a preferred embodiment, Figure 5 As shown, when the seal is released, the spring 6 is in a compressed state, the bottom of the cup pressing ring 4 is higher than the bottom of the sealing cover 3, and when the wall-breaking cup sealing device moves upward as a whole, the annular protrusion 41 of the cup pressing ring presses the annular protrusion 2 of the wall-breaking cup, and the sealing cover 3 moves upward. When the bottom of the cup pressing ring 4 is flush with the bottom of the sealing cover 3, the annular seal is separated from the close contact with the wall-breaking cup 1, and the seal is released. Example 2

[0034] The present invention aims to provide a wall-breaking cup sealing device, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the fixing plate 8 fixes the sealing cover 3 through the screw 9, and the fixing plate 8 is also connected to the cup pressing ring 4 through the guide column 5, the spring 6 sleeved on the guide column 5, and the screw 7; the cup pressing ring 4 is sleeved on the periphery of the sealing cover 3 and is in contact with it and can move relatively; an annular protrusion 41 is arranged at the bottom of the cup pressing ring 4, and when sealing, the annular protrusion 41 just presses the annular protrusion on the top edge of the wall-breaking cup 1; a first sealing ring 31 and a second sealing ring 32 are arranged at the bottom of the outer edge of the sealing cover 3; the cross-section of the wall-breaking cup 1 is an inverted trapezoid, and an outward annular protrusion 2 is arranged on the top of the wall-breaking cup 1, and the number of reinforcing protrusions arranged inside the wall-breaking cup 1 is 2-5.

[0035] At the beginning of sealing, the spring 6 is in a normal state, the bottom of the cup pressing ring 4 is flush with the bottom of the sealing cover 3, and when the wall-breaking cup sealing device moves downward as a whole, the annular protrusion 41 of the cup pressing ring first presses the annular protrusion 2 of the wall-breaking cup, and the sealing cover 3 continues to move downward, and the spring 6 is compressed, so that the annular seal is in close contact with the wall-breaking cup 1 to achieve sealing. Figure 1 Status shown.

[0036] like Figure 5 As shown, when the seal is released, the spring 6 is in a compressed state, the bottom of the cup pressing ring 4 is higher than the bottom of the sealing cover 3, and when the wall-breaking cup sealing device moves upward as a whole, the annular protrusion 41 of the cup pressing ring presses the annular protrusion 2 of the wall-breaking cup, and the sealing cover 3 moves upward. When the bottom of the cup pressing ring 4 is flush with the bottom of the sealing cover 3, the annular seal is separated from the close contact with the wall-breaking cup 1, and the seal is released.

[0037] like Figure 1 As shown, this sealing device is used for on-site preparation of beverages in vending machines, such as a mixture of one or more of cereals, oats, fruits, dairy products, and dried fruits. A wall-breaking knife or a stirring mechanism needs to pass through the sealing device of the present application. For this purpose, the fixed plate 8 and the middle part of the sealing cover 3 are provided with the space required for the wall-breaking rod and the wall-breaking knife to pass through.

[0038] In this embodiment, because the cross-section of the wall-breaking cup 1 is an inverted trapezoid, after the sealing cover 3 enters the wall-breaking cup 1, the further downward it goes, the greater the pressure on the cup body and the better the sealing. This will also make it difficult to release the seal when there is no external force interference, such as the annular protrusion 41 in the present application pressing the annular protrusion 2. At the same time, it may also cause the wall-breaking cup 1 to overturn. For this reason, we provide two annular sealing rings so that the sealing cover 3 can achieve good sealing by entering the wall-breaking cup 1 at a shorter distance, making it easier to release the seal.

[0039] In this embodiment, the wall breaking usually requires the rotation speed of the wall breaking knife to be above 25000r / min. In order to achieve the effect of quickly making drinks on site, short time is one of the key factors. In order to speed up the wall breaking, 2-5 reinforcing protrusions are arranged in the wall breaking cup 1, which helps the drink to rotate in a circle and tumble up and down in the wall breaking cup 1, which is beneficial to improve the cutting efficiency of the wall breaking knife and shorten the time.
