Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, specifically to a multi-functional sealing machine. Background Technology

[0002] Sealing machines are common tools in daily life. For example, they are used to extract gas from a bag and melt it with a heating mechanism to seal it. A typical sealing machine includes a base and a cover. The cover is hinged to the base. The end of the bag is placed on the base, and the cover is rotated to merge with the base to clamp the end of the bag. At the same time, the two form a vacuum chamber for drawing air. The air extraction mechanism inside the base, such as an air pump, is activated to extract the gas in the vacuum chamber. Simultaneously, the gas inside the bag flows out into the vacuum chamber. However, this type of sealing machine has a limited range of applications and cannot extract air from objects such as cans, so improvements are needed. Summary of the Invention

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a multi-functional sealing machine, including a base, a cover, and an air extraction mechanism. When the base and cover are in a combined state, the air extraction chamber formed between them is connected to the air inlet of the air extraction mechanism in the base. The base and cover work together to clamp the object to be extracted into the air extraction chamber. The machine also includes a connector for external air extraction. The connector is movably connected to the base. The base has a cavity that is connected to the air inlet of the air extraction mechanism, and the air inlet of the cavity is located at the connection between the connector and the base. The connector has an outlet and an inlet that are connected to its internal channel. The position of the connector can be adjusted relative to the base so that the outlet corresponds to the inlet to be in a connected state or misaligned to disconnect the connection.

[0005] This sealing machine is equipped with an external connector, which can be used to connect to bags to be vacuumed through the vacuum chamber, or to external containers to be vacuumed, depending on the needs, thus increasing the functionality of the sealing machine.

[0006] For the cavity, whether it is formed in the base or through an external pipe, the cavity is always connected to the air inlet of the vacuuming mechanism. When in use, if the position of the connector is adjusted so that the air outlet and the air inlet are misaligned, the bag can be vacuumed normally by clamping the end of the bag through the cover and the base. When vacuuming by connecting the connector to the tank to be vacuumed, adjust the position of the cover and the base so that they are in a combined state or close the passage between the vacuuming mechanism and the vacuuming chamber, and rotate the connector so that the air outlet and the air inlet of the cavity correspond to each other to connect. At this time, the tank at the connector can be vacuumed by the vacuuming mechanism.

[0007] Of course, the cavity can also be indirectly connected to the air inlet of the vacuum mechanism. For example, if the cavity is connected to the vacuum chamber, and the air inlet of the vacuum mechanism is also connected to the vacuum chamber, then the air inlet of the vacuum mechanism and the cavity are synchronously connected. When a vacuum is applied to the connected tank through the connector, the cover and the base are joined together to form a vacuum chamber. The gas extracted from the tank enters the vacuum chamber through the cavity and is then discharged through the vacuum mechanism.

[0008] The connector can be positioned on the base, such as at the end or on the side, depending on the requirements.

[0009] Furthermore, the connector is pivotally connected to the end face of the base, and its air outlet is located on its peripheral wall. The side wall of the mounting groove at the end face of the base for mounting the connector is provided with an air inlet for the cavity. The connector is rotated relative to the base so that its air outlet corresponds to or is misaligned with the second air inlet. In use, rotating the connector can connect or disconnect the connector from the cavity, which is convenient to use. The layout of placing the connector at the end face of the base helps to simplify the structure of the base. Only a groove for mounting the connector needs to be formed at the end, without the need to redesign many positions, which is convenient for forming and assembly.

[0010] Furthermore, it also includes a flexible adapter, which comprises a transverse portion and a longitudinal portion. The inner channel of the transverse portion is connected to the inner channel of the longitudinal portion. The end of the longitudinal portion is located in the second air inlet. The transverse portion is fitted onto the tail end of the connector. The connector is rotated relative to the flexible adapter so that its air outlet aligns with or is misaligned with the inlet of the channel in the longitudinal portion. Adding a flexible adapter helps improve the sealing of the connection, reduces leakage, and makes vacuuming easier.

[0011] Furthermore, the connector includes a cylindrical body and a post located at the tail end of the body. The diameter of the post is smaller than the diameter of the body. The internal channel of the post is connected to the internal channel of the body. The longitudinal part of the elastic adapter is sleeved on the post, and an air outlet connected to the internal channel of the post is provided on the peripheral wall of the post.

[0012] A limiting plate is provided on the main body or the insert post, and a limiting block is provided inside the base. The limiting block is located on the rotation path of the limiting plate to limit its rotation range.

[0013] The connector's structure is designed with a cylindrical body for easier insertion into tanks and other containers. The diameter of the insertion pin is adjustable; if it is smaller than the main body's diameter, it can be easily connected to a machine base for installation. The cooperation of the limiting plate and limiting block restricts the synchronous rotation of the connector, preventing excessive rotation that could cause leaks or other problems when the connector is inserted into the cavity.

[0014] Furthermore, the air outlet of the cavity is located at the cavity wall of the air extraction chamber so that the two are connected, which helps to simplify the structure.

[0015] Furthermore, it also includes a water storage tank. The base is provided with a slot and the water storage tank is inserted into the slot. The inlet pipe of the water storage tank extends from the bottom surface of the base. When the cover and the base are combined, the inlet pipe is in the vacuum chamber. The outlet pipe of the water storage tank is connected to the air inlet of the vacuum mechanism. The vacuum chamber is connected to the air inlet of the vacuum mechanism through the water storage tank. Thus, the moisture in the bag or other items to be vacuumed can remain in the water storage tank, avoiding any impact on the vacuum mechanism. This integrates the dry and wet separation function and is convenient to use.

[0016] Furthermore, a drain outlet is provided at the junction of the outlet pipe and the inlet pipe on the same plane as the tank body, with a sealing plug at the drain outlet. The ends of both the outlet and inlet pipes extend into the tank cavity. A baffle is installed around the end of the inlet pipe. The extension of the outlet and inlet pipes into the tank cavity increases the water storage capacity and reduces the frequency of replacements. A well-planned layout of the drain outlet and the inlet and outlet pipes facilitates the creation of larger drain outlets and shortens drainage time.

[0017] Furthermore, a magnetic chuck is provided on the cover or base, which attracts the sealing machine to the object to be installed, thus suspending the sealing machine. The magnetic chuck allows the sealing machine to be attached to the refrigerator for easy placement.

[0018] Furthermore, a mounting groove is provided on the upper side of the face of the base facing the cover, and a cutting tool is inserted into the mounting groove to increase the number of cutting tools. When needed, the cutting tool can be pulled out to cut the bag or the like.

[0019] Furthermore, the connector is slidably connected to the base, and the connector can be moved back and forth relative to the base so that its air outlet corresponds to or is misaligned with the air inlet.

[0020] Furthermore, the base includes an upper part and a lower part that are plugged together. A control board, battery, pressure sensor, and suction mechanism are located on the lower part facing the upper part. A cover is pivotally connected to the side of the lower part's bottom surface. A groove is provided on the cover facing the base, and a sealing strip is provided around the groove opening. A second sealing strip is provided on the base surface corresponding to the first sealing strip. When the cover and base are in a closed state, the first and second sealing strips abut against each other. A heating mechanism for sealing is provided within the annulus formed by the second sealing strip. A control button is located on the top surface of the upper part. The heating mechanism, suction mechanism, battery, control button, and pressure sensor are all connected to the control board. The pressure sensor detects the pressure in the suction chamber. When the pressure exceeds a set value, the control board stops the suction mechanism. The split upper and lower structure of the base facilitates the installation of the battery, suction mechanism, and other functional components, and facilitates assembly. The pressure sensor can work with the control board to provide overpressure protection, improving operational stability.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Example 1

[0036] like Figure 1 As shown, in this example, the multi-functional sealing machine includes a base 1, a cover 2, and an air extraction mechanism 6. The base 1 is connected to the cover 2, as follows: Figure 8 As shown in the configuration, the cover 2 is hinged to the side of the bottom surface of the base 1. During use, if the cover is... Figure 8 The unfolded state shown rotates towards the bottom surface of the base to merge with the base 1. Alternatively, the base and cover can be independent, and the cover can be fixed to the bottom surface of the base by means of clips or other means to merge. Or, the cover and base can be slidably connected in the thickness direction of the base, and the cover can be moved towards the bottom surface of the base to merge.

[0037] When the cover 2 and the base 1 are in the combined state, the cavity formed between them is the suction chamber 8. To improve sealing, sealing strips 15 and 16 can be installed on the faces of the cover 2 and the base 1 facing each other. For example, a ring made of elastic material such as rubber or sponge can be used as sealing strip 1 and sealing strip 2. Sealing strip 2 16 is fixed to the bottom surface of the base 1, and sealing strip 15 is fixed to the corresponding surface of the cover 2. When the cover 2 and the base 1 are in the combined state, sealing strips 15 and 16 abut against each other and cooperate with the bottom surface of the base and the corresponding cover surface within the ring to form the suction chamber 8. At the same time, the cover and the base in the combined state clamp the end of the bag that extends into the suction chamber.

[0038] An air extraction mechanism 6, such as a common air pump, is installed inside the base 1. The air inlet of the air extraction mechanism 6 is connected to the air extraction chamber 8 to extract gas from the air extraction chamber. The connection between the air extraction mechanism and the air extraction chamber can be achieved through a molding channel on the base or an external pipe, or through a water storage tank as described below.

[0039] In this example, the sealing machine is equipped with a connector 3 for external air extraction. Connector 3 can be plugged into external containers such as tanks, or inserted into the cavity of bags, tanks, or cylinders to be extracted. The connector's shape can be customized, such as a common cylindrical shape. Connector 3 has a channel formed inside for gas and liquid to pass through. This channel is connected to an air inlet (or outlet) on connector 3. For example, air inlet (or outlet) is located at the beginning of the connector, and outlet is located at the end. Connector 3 is movably connected to the base 1. The base 1 has a cavity that is connected to the air inlet of the extraction mechanism 6. The air inlet (or inlet 2) of the cavity is located at the connection point between the connector and the base. The position of the connector can be adjusted relative to the base. For example, if the outlet of the connector aligns with the air inlet (or inlet 2) of the cavity, they are in a connected state, and air can be extracted from the container connected to the connector via the extraction mechanism. Alternatively, the air outlet of the connector can be misaligned with the air inlet of the cavity, thus disconnecting the connection and not affecting the extraction of gas from the extraction chamber by the extraction mechanism.

[0040] Regarding the specific connection structure between the connector and the base, for example, connector 3 is pivotally connected to the base, specifically as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a mounting groove is formed at the end face of the base 1. The tail end of the connector 3 is located in the mounting groove and can rotate relative to the base. If the axial centerline of the base is taken as the rotation centerline, the connector can be rotated left or right during use. The air outlet 33 of the connector 3 is located on the peripheral wall of its tail end, and the air inlet 20 is located on the side wall of the mounting groove. The air inlet 2 is located on the moving path of the air outlet 33. When the connector is rotated so that the air outlet 33 is opposite to the air inlet 2, the connection is established. When the connector is rotated so that the air outlet and the air inlet 2 are misaligned, the connection is broken.

[0041] To improve sealing, a flexible adapter 13 can be added, which is an adapter 13 molded from an elastic material, such as rubber. The flexible adapter 13 includes a transverse portion 132 and a longitudinal portion 131, which are connected as follows: Figure 4 The L-shape shown can, of course, be replaced with other configurations, where the inner channel of the transverse portion 132 is connected to the inner channel of the longitudinal portion 131. For example... Figure 3 As shown, the end of the longitudinal part 131 is located in the second air inlet of the cavity 20, and the transverse part 132 is fitted onto the tail end of the connector 3. Under the elastic covering, it helps to improve the sealing performance. When in use, if the connector is rotated relative to the elastic adapter so that its air outlet corresponds to the inlet of the longitudinal part, it will also correspond to the second air inlet of the cavity. Alternatively, if its air outlet is misaligned with the inlet of the longitudinal part, it will also be misaligned with the second air inlet of the cavity.

[0042] For ease of installation, connector 3 in this example adopts the following method: Figure 4The configuration shown includes a cylindrical main body 31 and a column, i.e., an insert 32, located at the tail end of the main body. The diameter of the insert 32 is smaller than the diameter of the main body 31. The internal channel of the insert 32 is connected to the internal channel of the main body 31. The longitudinal part of the flexible adapter 13 is fitted onto the insert 32. An air outlet 33 communicating with the internal channel is formed on the peripheral wall of the tail end of the insert 32. In this configuration, the diameter of the insert is small, eliminating the need to form a large-diameter mounting groove at the base, which facilitates the design of the base configuration and easy docking with the base. In use, the main body is fitted onto the opening of the tank, and then the gas is extracted by the suction mechanism. Of course, the diameter of the main body can also be reduced, and it can be inserted into the opening of the tank or other bags to be vacuumed. A sealing ring can be installed on the end face of the main body to help improve the sealing performance when docking with tanks, etc. Of course, other configurations of the connector can also be selected, such as L-shaped, stepped shaft-shaped, single-diameter cylinder, etc. The appropriate connector configuration can be selected according to the inlet configuration of the object from which the gas needs to be extracted, and there is no limitation.

[0043] To limit the rotation range of the connector, a limiting plate 100 is added in this example, such as... Figure 3 , Figure 4 As shown, the limiting plate 5 is fitted onto the insert post 32 through the central hole. The limiting plate 5 is fixed to the tail end face of the main body 31 by screws, etc. A limiting block 100 is formed on the wall of the mounting groove of the base 1. The limiting block 100 is located on the rotation path of the side of the limiting plate. If the two limiting blocks are placed at intervals, the limiting plate rotates synchronously when the connector is rotated. The upper left side of the limiting plate 5 abuts against one of the limiting blocks to limit its continued rotation. At this time, the air outlet corresponds to the second air inlet of the cavity. When the connector is rotated, the upper right side of the limiting plate 5 abuts against the other limiting block to limit its continued rotation. At this time, the air outlet 33 is misaligned with the second air inlet of the cavity 20. The two limiting blocks limit the rotation range of the connector, making it convenient to rotate the connector to change the connection state between the air outlet and the cavity. In addition, the limiting plate can also be longer than the diameter of the groove opening of the mounting groove at the end face or the diameter of a certain section of the mounting groove to limit the connector from being pulled outward relative to the base.

[0044] As for the location of the connector, it can also be placed on the side of the base or other locations as needed, depending on the requirements.

[0045] Of course, a structure in which the connector and the base slide together can also be adopted. For example, the connector slides along the length of the base and fits into the base. Similarly, an air inlet 2 is placed on the side wall of the mounting groove, and an air outlet is formed on the peripheral wall of the tail end of the connector. The connector slides back and forth relative to the base so that the air outlet and the air inlet 2 are opposite to each other to connect or are misaligned to disconnect the connection, depending on the requirements.

[0046] For cavities, they can be formed by external flexible tubes or rigid tubes, or by holes or flow channels formed in the base, or by a combination of both. The cavity and the air inlet of the suction mechanism can be directly or indirectly connected. For example, the end outlet of the cavity is directly connected to the air inlet of the suction mechanism, i.e., directly connected.

[0047] This example demonstrates indirect connectivity, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 A cavity 20 is formed within the base 1. The outlet of cavity 20 is located on the wall of the suction chamber 8, communicating with it. Specifically, the outlet of cavity 20 extends to the bottom surface of the base 1 (simultaneously positioned within the annular opening of the second sealing strip). The suction chamber 8 is simultaneously connected to the first air inlet of the suction mechanism 6, ensuring that cavity 20 is also connected to the first air inlet of the suction mechanism. When drawing gas through the connector, the cover and base must be in a closed state. When drawing gas from the bag or other parts through the suction chamber, the outlet of the connector and the second air inlet of the cavity must be misaligned.

[0048] Given that some bags contain water, a water tank 4 is added in this example to avoid affecting the air extraction mechanism. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, a slot 101 is formed on the top surface of the base 1, and the water tank 4 is plugged into the slot 101. The water tank can be pulled out to drain water as needed. An insertion hole 106 is formed on the wall of the slot 101. When the water tank is installed, the inlet pipe 41 on its body is inserted into the insertion hole and extends from the bottom surface of the base 1, also within the ring of the sealing strip. When the cover and the base are closed, the inlet pipe is in the suction chamber. The outlet pipe 43 on the body of the water tank 4 (such as using a hole as the outlet pipe, or an outwardly protruding pipe as the outlet pipe) is connected to the air inlet of the suction mechanism 6. If connected by a hose, the suction chamber is connected to the air inlet of the suction mechanism through the water tank. During use, the moisture in the bag or other items to be vacuumed can remain in the water tank, avoiding affecting the suction mechanism, thus integrating a dry and wet separation function.

[0049] To improve the dry-wet separation function and facilitate drainage, the structure of the water storage tank is designed in this example. Specifically, the first end of the outlet pipe 43 and the first end of the inlet pipe 41 are on the same plane of the tank body, and a drain outlet is formed on the tank surface between them. A sealing plug 42 is installed at the drain outlet for sealing. The tail ends of the outlet pipe 43 and the inlet pipe 45 both extend into the tank cavity of the water storage tank 4, and a baffle 44 surrounds the tail end of the inlet pipe. The baffle is connected to the tank wall to limit water splashing. The tail ends of the outlet pipe and the inlet pipe extend into the tank cavity, and the tail end of the outlet pipe is at a predetermined height from the tank wall below it to prevent water discharged from the tail end of the inlet pipe from flowing directly into the outlet pipe. This design also increases the water storage capacity of the water storage tank. When drainage is needed, the water storage tank can be pulled out directly, and the sealing plug can be removed for drainage.

[0050] To facilitate the storage and handling of the sealing machine, a magnetic suction element 19 is added in this example, such as... Figure 3 As shown, a magnetic suction component 19 is fitted and fixed at the bottom surface of the cover 2. Alternatively, it can be fixed using screws or similar means. The magnetic suction component 19 can be selected as follows: Figure 3 The strip magnet shown can, of course, be composed of multiple independent blocks; its configuration is not limited and can be selected according to needs. The magnetic force of the magnetic attachment can be chosen. In this example, the sealing machine can be magnetically attached to the refrigerator door, suspended in a suspended state, eliminating the need for a dedicated installation location. Alternatively, the magnetic attachment can be mounted on a base, depending on requirements.

[0051] You can also add cutting tools, such as Figure 3 , Figure 8 As shown, a groove is formed on the side of the base 1 facing the cover 2, which is called the mounting groove. The tool 10 is inserted into the mounting groove. The type of tool can be selected according to the needs, such as blades or blades for gripping. When needed, the tool can be pulled out to cut the bag, etc.

[0052] To facilitate locking the cover, a locking mechanism can be added, such as a locking base 104 and a buckle 21. The buckle 21 is installed on the cover 2, and the locking base 104 is elastically connected to the side of the base 1 by a spring. When the cover and the base are combined, the buckle is inserted into the slot on the locking base that cooperates with the buckle, thereby locking the cover in its position. The locking base can be pressed to separate the buckle from the slot, at which time the cover can be rotated relative to the base.

[0053] For ease of control and use, this sealing machine also includes a control board 9, a battery 7, and a pressure sensor 12. For ease of installation, the base 1 in this example is a modular assembly type, such as... Figure 7 , Figure 3 , Figure 2As shown, the base 1 includes an upper part 102 and a lower part 103 that are plugged into each other. The lower part 103 is inserted into the cavity of the upper part 102. A control board 9, a battery 7, a pressure sensor, and a suction mechanism 6 are installed on the surface of the lower part 103 facing the upper part 102. The pressure sensor 12 is mounted on the control board 9. An air hole 105 for the pressure sensor to detect pressure extends to the bottom surface of the base 1 and is located in the annulus of the sealing strip 2 to detect the pressure in the suction chamber. A cavity is formed at the lower part to mate with the connector.

[0054] The cover 2 is pivotally connected to the side of the bottom surface of the lower part 103. The surface of the cover 2 facing the base is formed with a groove and a sealing strip 15 is placed around the groove opening. The groove is increased to improve the water output and pre-store the liquid extracted from the bag body. Then, it is extracted into the water storage tank through the air inlet pipe.

[0055] The heating mechanism 14 for sealing is located on the bottom surface of the base 1 within the ring formed by the sealing strip 16. A pressure strip 18 made of elastic material can be added to the corresponding position on the cover 2. When the cover and base are joined, the pressure strip 18 and the heating mechanism 14 clamp the end of the bag. The heating mechanism heats and melts the bag to seal it. The heating mechanism can be selected from the market according to requirements; common types include heating wire types. A support foot 17 can also be added, fixed to the surface of the cover 2 facing the base. When the cover and base are joined, the support foot 17 abuts against the bottom surface of the base. The size of the support foot can be predetermined to limit the degree of merging between the cover and base, preventing excessive clamping of the bag end and slowing down the vacuuming speed.

[0056] A control button 11 is installed on the top surface of the upper part 102. The heating mechanism 14, the suction mechanism 6, the battery 7, the control button 11, and the pressure sensor 12 are all connected to the control board 9. The control button 11 is as follows: Figure 1 , Figure 3 The multiple options shown can be used to perform dry pumping mode, wet pumping mode, air extraction chamber, air extraction connector, etc. In wet pumping mode, the air extraction time is longer than that in dry pumping mode.

[0057] During use, the pressure sensor is used to detect the pressure in the suction chamber. When the pressure exceeds the set pressure, the control board stops the suction mechanism, thus providing overpressure protection.

[0058] During assembly, the various functional mechanisms can be pre-installed on the upper part and then plugged into the lower part to form the base.

[0059] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
