Description

Technical Field

[0001] This utility model relates to the technical field of sealing equipment, specifically to a sealing device. Background Technology

[0002] With the rapid development of modern commerce, consumption patterns have undergone tremendous changes. In the traditional retail industry, the checkout process relies on manual operation, which is extremely inefficient and often leads to long queues for customers. This not only affects the shopping experience but also fails to meet the modern commercial demands for efficiency and convenience, gradually becoming unsuitable for the increasingly fierce commercial competition. To adapt to the new commercial development trend, vending machines have emerged and quickly demonstrated vigorous development.

[0003] However, existing vending machines have significant limitations in their application scenarios. Their product range is mostly limited to packaged goods that can be stored at room temperature, such as bottled beverages and candies / snacks, with very few options for food types that require on-site heating. This greatly restricts the variety of goods and application scenarios available to vending machines, making it difficult to meet consumers' demand for instant hot food.

[0004] Currently, commercially available heated vending machines face several technical design bottlenecks. They typically feature a microwave unit located below the storage area, with an opening at the top for food to fall into the microwave for heating. To ensure heating reliability, existing technology usually incorporates a movable sealing plate above the microwave unit, which seals the opening during heating. However, this design has a significant drawback: gaps can easily appear between the sealing plate and the top surface of the microwave unit due to assembly and movement errors. This not only allows heat to escape through these gaps, reducing heating efficiency but also increases energy consumption.

[0005] Therefore, existing technologies still need further development. Utility Model Content

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] Please see Figures 1 to 5According to an embodiment of the present invention, a sealing device is provided for sealing or opening the feed inlet 101 of a microwave device 100 in a hot food machine. The sealing device includes a sealing member 1 for being disposed above the microwave device 100, and the sealing member 1 is movably disposed relative to the microwave device 100 along a preset direction. The sealing member 1 has a sealing position for sealing the feed inlet 101 and a clearance position for avoiding the feed inlet 101. The sealing member 1 has a cover 11 and a sealing door 12. The bottom of the cover 11 is provided with a placement groove 110, and at least a portion of the sealing door 12 is located in the placement groove 110. The cover 11 and the sealing door 12 are positionally adjustable. When the sealing member 1 is in the sealing position, the sealing door 12 is made to abut against the top plate 103 of the microwave device 100 by adjusting the relative position between the cover 11 and the sealing door 12.

[0028] As can be seen, the sealing device provided by this utility model is disposed above the microwave device 100 inside the hot food machine. This sealing device is used to block or avoid the feed inlet 101 located at the top of the microwave device 100, thereby opening or closing the feed inlet 101. The sealing device includes a sealing member 1, which is disposed above the microwave device 100 and is movably disposed relative to the microwave device 100 along a preset direction to block or avoid the feed inlet 101 of the microwave device 100. The sealing member 1 has a blocking position for blocking the feed inlet 101 and an avoidance position for avoiding the feed inlet 101. Meanwhile, the sealing component 1 has a cover 11 and a sealing door 12. The bottom of the cover 11 is provided with a placement groove 110, and at least a portion of the sealing door 12 is located within the placement groove 110. The cover 11 and the sealing door 12 are connected in an adjustable manner. Furthermore, when the sealing component 1 is in the sealing position, the sealing door 12 can be brought into contact with the top plate 103 of the microwave device 100 by adjusting the relative position between the cover 11 and the sealing door 12. Thus, the sealing component 1 can flexibly switch between a sealing position and a clearance position, ensuring that food is only allowed to enter the heating space when needed, avoiding unnecessary food transfer, and improving the system's response speed and operating efficiency. Moreover, the design of the sealing component 1 can block the feed inlet 101 in the non-operating state, preventing food from accidentally entering the heating space under any circumstances, reducing food waste or equipment malfunctions caused by misoperation. Meanwhile, the sealing component 1 consists of a cover 11 and a sealing door 12. The bottom of the cover 11 has a placement groove 110, and the sealing door 12 is at least partially located within the placement groove 110, with their positions adjustable. This design not only provides physical sealing but also achieves a better sealing effect by adjusting the relative position between the sealing door 12 and the top plate 103 of the microwave device 100, effectively preventing microwave leakage. Furthermore, by adjusting the relative position between the cover 11 and the sealing door 12, manufacturing errors or installation deviations can be compensated for, ensuring optimal contact between the sealing door 12 and the top plate 103 of the microwave device 100, thereby achieving a better sealing effect. This flexible design can adapt to different installation and usage conditions, ensuring effective sealing and preventing microwave leakage under various circumstances. In addition, by introducing this sealing device with a cover 11 and a sealing door 12, the hot food machine not only achieves precise control over the entry of food into the heating space but also significantly improves the system's sealing performance and operational reliability. This sealing device is simple to operate and can effectively solve the technical problem of incomplete sealing between the sealing plate and the microwave device in the existing technology.

[0029] Specifically, such as Figure 2As shown, the sealing component 1 further includes: a connector 13 and an elastic member 14. The connector 13 passes through the cover 11 and is connected to the sealing door 12. The connector 13 is movably disposed relative to the cover 11 in the vertical direction, and the connector 13 is fixedly connected to the sealing door 12. The elastic member 14 is sleeved on the connector 13 and is located in the placement groove 110. The elastic member 14 abuts against the cover 11 and the sealing door 12 respectively. When the sealing component 1 is in the sealing position, the sealing door 12 contacts the top plate 103 of the microwave device 100, so that the sealing door 12 and the connector 13 move upward in the vertical direction relative to the cover 11, so that the elastic member 14 is in a compressed state. Under the action of the elastic force of the elastic member 14, the sealing door 12 abuts against the top plate 103 of the microwave device 100. When the sealing element 1 is in the avoidance position, it is spaced apart from the top plate 103 of the microwave device 100. The elastic element 14 then returns from its compressed state to its natural state, and the self-restoring force of the elastic element 14 causes the sealing door 12 and the connecting element 13 to move vertically downwards relative to the cover 11. This structural arrangement, with the elastic element 14, allows the sealing door 12 to dynamically adjust according to the flatness of the actual contact surface, ensuring a tight fit under different conditions and thus improving the sealing effect. When the sealing door 12 contacts the top plate 103 of the microwave device 100, the elastic element 14 is compressed, generating a reverse elastic force, ensuring that the sealing door 12 always maintains good contact with the top plate, compensating for even slight surface unevenness or installation errors. Furthermore, through the action of the elastic element 14, the sealing door 12 can better fit the top plate 103 of the microwave device 100, significantly reducing the risk of microwave leakage and protecting the safety of the external environment and the internal structure of the equipment. Furthermore, since the elastic element 14 can absorb impact and vibration to a certain extent, it reduces direct wear between mechanical parts, thereby extending the overall service life of the sealing device.

[0030] Furthermore, the connector 13 passes through the cover 11 and is threadedly connected to the sealing door 12. Preferably, the connector 13 is a connecting stud; the elastic element 14 is a spring, which is sleeved on the connecting stud.

[0031] Specifically, such as Figure 2 As shown, the sealing component 1 also includes: a bushing 15, which is inserted into the cover 11 and is fixedly connected to the cover 11; the bushing 15 extends in the vertical direction and has a guide channel extending in the extension direction of the bushing 15; the connector 13 passes through the guide channel and is fixedly connected to the sealing door 12.

[0032] Specifically, such as Figure 1As shown, there are multiple connectors 13, which are spaced apart along the edge of the cover 11; there are also multiple elastic elements 14 and bushings 15, with each connector 13 corresponding to each elastic element 14 and each bushing 15.

[0033] Optionally, there are four connectors 13, which are spaced apart along the edge of the cover 11.

[0034] Specifically, such as Figures 2 to 4 As shown, the sealing door 12 includes: a sealing door body 121, with a choke groove 120 at the bottom of the sealing door body 121; the choke groove 120 is arranged around the edge of the sealing door body 12; the choke groove 120 is used to guide or restrict the propagation path of electromagnetic waves; wherein, when the sealing member 1 is in the sealing position, at least a portion of the sealing door body 121 abuts against the top plate 103 of the microwave device 100; and the choke groove 120 communicates with the heating space of the microwave device 100. With this structural arrangement, the choke groove 120, arranged around the edge of the sealing door body 12, can effectively guide or restrict the propagation path of electromagnetic waves, preventing microwaves from leaking out of the heating space. At the same time, the design of the choke groove 120 can significantly reduce the possibility of microwaves leaking from the heating space into the external environment, improving the safety of equipment use and protecting operators and the surrounding environment. Furthermore, by preventing microwave leakage, it ensures that microwave energy is concentrated within the heating space, improving heating efficiency and reducing energy loss. In addition, combined with the function of the elastic element 14, the sealing door body 121 is tightly fitted with the top plate 103 of the microwave device 100, while the choke groove 120 further enhances the sealing effect, forming a dual protection mechanism.

[0035] Specifically, such as Figures 2 to 4 As shown, the sealing door body 121 includes: a connecting plate 1211, an abutting part 1212, and a fixing part 1213. The connecting plate 1211 is used to connect to the cover 11. The abutting part 1212 is disposed at the bottom of the connecting plate 1211 and is arranged around the edge of the connecting plate 1211. The abutting part 1212 is used to abut against the top plate 103 of the microwave device 100. The fixing part 1213 is disposed at the bottom of the connecting plate 1211 and is fixedly connected to the connecting plate 1211. The fixing part 1213 and the abutting part 1212 are spaced apart. The fixing part 1213, the connecting plate 1211, and the abutting part 1212 form a choke groove 120.

[0036] Specifically, such as Figure 3 and Figure 4As shown, the sealed door 12 further includes a guide portion 122, which is disposed at the bottom of the fixing portion 1213 and fixedly connected to the fixing portion 1213. The guide end of the guide portion 122 faces the choke groove 120, and the guide portion 122 and the abutment portion 1212 are spaced apart, forming an inlet 130 communicating with the choke groove 120 between the guide portion 122 and the abutment portion 1212. The guide portion 122 is used to guide electromagnetic waves through the inlet 130 into the choke groove 120. With this structural arrangement, the guide portion 122 is disposed at the bottom of the fixing portion 1213, and its guide end faces the choke groove 120, which can effectively guide any potentially leaking electromagnetic waves into the choke groove 120. This ensures that microwave energy is confined within the heating space, reducing interference to the outside world. The inlet 130 formed between the guide portion 122 and the contact portion 1212 not only helps guide electromagnetic waves into the choke groove 120, but also serves as an additional sealing barrier to prevent microwave leakage from other directions. Furthermore, the combined design of the guide portion 122 and the choke groove 120 significantly reduces the possibility of microwave leakage from the heating space to the external environment, improving the safety of equipment use and protecting operators and the surrounding environment.

[0037] Specifically, such as Figures 2 to 4As shown, the guide portion 122 includes: a rectangular plate 1221, which is fixedly connected to the fixing portion 1213 and is located at the bottom of the fixing portion 1213; a first guide plate 1222, a second guide plate 1223, a third guide plate 1224, and a fourth guide plate sequentially disposed on the edge of the rectangular plate 1221; the first guide plate 1222 and the third guide plate 1224 are disposed opposite to each other, and the second guide plate 1223 and the fourth guide plate are disposed opposite to each other; the first guide plate 1222, the second guide plate 1223, the third guide plate 1224, the fourth guide plate 1225, the fourth guide plate 1226, the fourth guide plate 1227, the fifth guide plate 1228, the fifth guide plate 1229, the fifth guide plate 1220, the sixth guide plate 1221, the fifth guide plate 1221, the sixth guide plate 1222, the fifth guide plate 1221, the sixth guide plate 1222, the sixth ... The three guide plates 1224 and the fourth guide plate are inclined upward relative to the rectangular plate 1221; and the ends of the first guide plate 1222, the second guide plate 1223, the third guide plate 1224, and the fourth guide plate all face the choke groove 120, so as to guide electromagnetic waves into the choke groove 120 through the first guide plate 1222, the second guide plate 1223, the third guide plate 1224, and the fourth guide plate. With this structural arrangement, the four guide plates (first guide plate 1222, second guide plate 1223, third guide plate 1224, and fourth guide plate) are located at the edge of the rectangular plate 1221 and are inclined upward relative to the rectangular plate 1221. This layout can ensure that electromagnetic waves leaking from multiple directions can be effectively guided into the choke groove 120. All guide plates have their ends furthest from the rectangular plate facing the choke groove 120, ensuring that electromagnetic waves are concentrated and guided to the choke groove 120 after entering the guide plates. This confines microwave energy within the heating space and reduces interference to the outside environment. Furthermore, the combination of the guide plates and the choke groove 120 forms a multi-layered protection system. Each guide plate not only guides electromagnetic waves but also acts as an additional physical barrier to prevent microwave leakage from other directions.

[0038] Specifically, such as Figure 3 and Figure 4As shown, the guide section 122 is provided with multiple guide grooves 1226, which are spaced apart and uniformly connected to the choke groove 120. Each guide groove 1226 extends along a preset trajectory. When the microwave device 100 is running, the sealing member 1 is in the sealing position. Electromagnetic waves within the microwave device 100 can enter the choke groove 120 through the guide grooves 1226, or the electromagnetic waves entering the choke groove 120 can be guided to the heating space of the microwave device 100 through the guide grooves 1226. This structural arrangement, with multiple guide grooves 1226 spaced apart and uniformly connected to the choke groove 120, allows electromagnetic waves leaking from different directions to be effectively dispersed and guided into the choke groove 120, ensuring that microwave energy is confined within the heating space. The guide grooves 1226 extending along a preset trajectory allow electromagnetic waves to be guided along a specific path, thereby improving the accuracy and efficiency of overall electromagnetic wave management. The guide groove 1226 can not only guide the electromagnetic waves in the microwave device 100 into the choke groove 120, but also guide the electromagnetic waves that have entered the choke groove 120 back into the heating space, forming a closed-loop management system, which further reduces the possibility of microwave leakage.

[0039] Furthermore, each guide groove 1226 is formed on the edge of the rectangular plate 1221, and each guide groove 1226 extends along the inclined direction of each guide plate and extends to the side of each guide plate away from the rectangular plate 1221.

[0040] Specifically, such as Figures 1 to 5 As shown, the blocking device also includes: a mounting frame 2, which is disposed on the top of the microwave device 100, and the blocking component 1 is movably disposed on the mounting frame 2; and a transmission mechanism 3, which is movably disposed on the mounting frame 2, and the output part of the transmission mechanism 3 is connected to the blocking component 1 so as to drive the blocking component 1 to reciprocate along a preset direction through the transmission mechanism 3, so that the blocking component 1 is in a blocking position or an avoidance position.

[0041] Furthermore, such as Figures 1 to 5 As shown, the mounting bracket 2 includes two guide brackets 21, which are spaced apart along the width direction of the top plate 103 and extend along a predetermined direction (i.e., along the length direction of the top plate 103). Each guide bracket 21 has a first guide channel 210 and a second guide channel 211 extending from the guide bracket 21 to the second guide channel 211, which are spaced apart along the predetermined direction. The first guide channel 210 is located at the end of the guide bracket 21 closest to the top plate 103.

[0042] Each guide bracket 21 has a first locking groove 212 and a second locking groove 213. The first locking groove 212 communicates with the first guide channel 210 and is located at the end of the first guide channel 210 away from the second guide channel 211. The bottom wall of the first locking groove 212 is located below the first guide channel 210. The second locking groove 213 communicates with the second guide channel 211 and is located at the end of the second guide channel 211 closer to the first guide channel 210. The bottom wall of the second locking groove 213 is located below the second guide channel 211.

[0043] Furthermore, the sealing device also includes two sets of guide wheels 4, which are spaced apart along the length of the top plate 103. Each set of guide wheels 4 has two guide wheels 4, which are rotatably mounted on both sides of the sealing member 1 along the width of the top plate 103. Two guide wheels 4 in one set of guide wheels 4 are rotatably mounted on the corresponding first guide channel 210 and first locking groove 212. Two guide wheels 4 in the other set of guide wheels 4 are rotatably mounted on the corresponding second guide channel 211 and second locking groove 213. When the sealing member 1 moves from the avoidance position to the sealing position, each guide wheel 4 enters the corresponding locking groove through the corresponding guide groove to lock the corresponding guide wheel 4. Simultaneously, when each guide wheel 4 enters the corresponding locking groove, it drives the sealing member 1 to move downwards towards the top plate 103. This ensures that the sealing door 12 fits tightly against the top plate 103, further improving the sealing performance.

[0044] Specifically, such as Figure 3 and Figure 4 As shown, the transmission mechanism 3 includes a first transmission wheel 31 and a second transmission wheel 32. The first transmission wheel 31 and the second transmission wheel 32 are spaced apart on the mounting frame 2 along the length of the top plate 103, and are rotatably arranged relative to the mounting frame 2. The first transmission wheel 31 and the second transmission wheel 32 are located at the bottom of the mounting frame 2. The transmission mechanism 3 also includes a synchronous belt 33 and a moving member 34. The synchronous belt 33 is sleeved on the first transmission wheel 31 and the second transmission wheel 32 and is connected to drive the synchronous belt 33 through the first transmission wheel 31 or the second transmission wheel 32. The moving member 34 is connected to the sealing member 1 and the synchronous belt 33 respectively, so that the moving member 34 is driven by the synchronous belt 33 to move in a preset direction, thereby driving the sealing member 1 to move.

[0045] Furthermore, the mounting bracket 2 is provided with a guide rod 5, which extends along a preset direction; the movable part 34 is movably sleeved on the guide rod 5.

[0046] Furthermore, the sealing component 1 also includes: a connecting bracket 16, which is fixedly connected to the cover 11 and located on the side of the cover 11 near the movable component 34. The connecting bracket 16 has a moving groove 160 extending vertically. The sealing device also includes: a limiting post 7, which extends along the width of the top plate 103 and is movably inserted into the moving groove 160 vertically. The sealing component 1 and the movable component 34 are connected via the connecting bracket 16 and the limiting post 7.

[0047] The movable part 34 forms the output part of the transmission mechanism 3.

[0048] Furthermore, the sealing device also includes a drive mechanism 6, which is drivenly connected to the transmission mechanism 3, and the drive mechanism 6 drives the sealing component 1 to move through the transmission mechanism 3.

[0049] Optionally, the process of the sealing device sealing the feed inlet 101 is as follows:

[0050] When food enters the heating space of the microwave device 100 through the feed inlet 101, the drive mechanism 6 moves, and the drive mechanism 6 drives the sealing member 1 from the avoidance position to the sealing position through the transmission mechanism 3. When the sealing member 1 moves to the sealing position, each guide wheel 4 moves into the corresponding locking groove, and then the sealing member 1 moves down, so that the sealing member 1 contacts the top plate 103.

[0051] When the sealing element 1 contacts the top plate 103, the sealing door 12 and the connecting element 13 move upward in the vertical direction relative to the cover 11, so that the elastic element 14 is in a compressed state; and under the action of the elastic force of the elastic element 14, the sealing door 12 abuts against the top plate 103 of the microwave device 100, thus completing the sealing process. In addition, when the sealing element 1 moves downward, the limiting post 7 moves upward in the vertical direction relative to the moving groove 160.
