Description

Technical Field

[0001] This utility model belongs to the field of switch technology, and in particular relates to a switch structure applied to a sealed container. Background Technology

[0002] A sealed container is a holding vessel with a sealed structure that can isolate or control the exchange of gases, liquids, dust, and other substances between its interior and the outside environment. In various applications of sealed containers, such as food storage boxes, thermos flasks, and vacuum storage bags, the performance of their opening and closing mechanisms directly affects the user experience and sealing effect. Existing sealing container opening and closing mechanisms often suffer from problems such as complex operation, unstable sealing performance, and difficulty in quickly switching between sealed and ventilated states. Common switches typically require users to perform multiple steps (such as rotating, pressing, or lifting) to seal or open, resulting in a poor user experience. Some switch structures require multiple presses or adjustments to achieve a seal, requiring users to remember complex operating sequences or apply varying degrees of force, easily leading to misoperation. Furthermore, during the sealing process, excess air inside the container cannot be effectively expelled, making it difficult to create an ideal negative pressure environment, thus affecting the sealing effect and preservation / heat retention performance. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a switch structure for use in sealed containers to meet the needs of users.

[0004] To achieve the above objectives, this utility model provides a switch structure for use in sealed containers, including...

[0005] The actuating components include a button and a spring.

[0006] The transmission assembly includes a slide column disposed on the button.

[0007] The switch body includes an exhaust channel and a tracking groove. The exhaust channel is adapted to connect to the exhaust channels inside and outside the sealed container. The sliding column can move unidirectionally within the tracking groove. The tracking groove includes a first locking position, a second locking position, a first braking position, and a second braking position. The sliding column is adapted to move from the first braking position to the first locking position under the guidance of a first sliding in guide portion. The sliding column is also adapted to move from the first locking position to the second braking position under the guidance of a first sliding out guide portion. The second locking position is connected to both the first braking position and the second braking position.

[0008] A valve plate adapted to seal the exhaust passage, and a spring abutting between the button and the valve plate.

[0009] The button is adapted to drive the slide column from the second locking position to the first braking position. The valve plate is pressed to squeeze out part of the air in the sealed container and seal the exhaust channel to form a negative pressure space. The spring is adapted to drive the slide column to lock in the first locking position. At this time, the valve plate keeps the exhaust channel sealed. The button is adapted to drive the slide column from the first locking position to the second braking position. The spring is adapted to drive the slide column to move to the second locking position to restore the locking engagement. At this time, the exhaust channel is open.

[0010] Preferably, the track limiting groove has a heart-shaped structure. The track limiting groove includes a second sliding in guide portion, a second sliding out guide portion, a first stroke groove and a second stroke groove. The second sliding in guide portion and the second sliding out guide portion extend to both sides of the second locking position, respectively. The first stroke groove is adapted to connect the second sliding out guide portion and the first braking position, and the second stroke groove is adapted to connect the second braking position and the second sliding in guide portion.

[0011] Preferably, the switch body includes a base and several surrounding plates. The exhaust channel is formed at the center of the base, and the tracking groove is formed in the surrounding plate. A central axis L is defined, which is adapted to pass through the center of the base and be perpendicular to the base. The surrounding plates are evenly distributed circumferentially around the central axis L. The surrounding plates are arc-shaped plates.

[0012] Preferably, the button includes a pressure-bearing top plate, a peripheral wall surrounding the pressure-bearing top plate, and a plurality of support plates extending downward from the peripheral wall. The sliding column protrudes from the support plate and is evenly distributed around the central axis L.

[0013] Preferably, the first locking position, the second locking position, the first braking position, and the second braking position all include an arc-shaped surface suitable for conforming to the shape of the sliding column; the first stroke groove is arranged along the direction of the central axis L, and the second stroke groove is arranged along the direction of the central axis L, which simplifies part of the motion trajectory.

[0014] Preferably, the spring directly abuts against the valve plate, or the spring abuts against the valve plate through a pressure transmitting member, one side of the pressure transmitting member maintaining contact with the valve plate, and the other side of the pressure transmitting member being adapted to abut against the spring.

[0015] Preferably, the valve plate includes a valve plate body and a support column supported below the valve plate body. A support sleeve suitable for supporting the support column is formed in the center of the exhaust channel. The valve plate body is suitable for completely covering the exhaust channel. The pressure transmitting element includes a pressure transmitting plate and a plurality of cantilever arms connected to the pressure transmitting plate. The cantilever arms are connected to the base to support the pressure transmitting plate. The pressure transmitting plate is in contact with the valve plate body.

[0016] Preferably, the valve body is horn-shaped or spherical in its natural state. The valve body includes an open end and a converging end, with the open end facing the button. This design allows the valve body to effectively gather and guide the airflow below to the exhaust channel during the pressurized exhaust phase, accelerating air discharge, promoting the rapid formation of negative pressure space inside the container, and optimizing the vacuum effect. At the same time, the resetting tendency of the valve body facilitates the smooth reopening of the exhaust channel.

[0017] Preferably, the button includes a first limiting groove extending downward from the inner surface of the pressure-bearing top plate, the first limiting groove being adapted to receive one end of the spring; a second limiting groove is formed on the upper surface of the pressure-transmitting plate; both ends of the spring are respectively received in the first limiting groove and the second limiting groove; and a pressure ring extends downward from the lower surface of the pressure-transmitting plate, the pressure ring being in contact with the valve plate body. This design effectively limits the position of the spring and the valve plate, ensuring accurate force transmission path and reliable operation. The radial dimension of the pressure ring is smaller than that of the exhaust channel.

[0018] Preferably, the switch body further includes several reinforcing ribs supported below the exhaust channel, the reinforcing ribs being arranged radially, and the support sleeve being disposed in the center of the reinforcing ribs.

[0019] Preferably, the switch body further includes a cover adapted to cover the enclosure, the cover including a clearance that allows the button to extend and retract, the switch body including an annular support plate and a screw ring, the annular support plate being adapted to support the cover, the cover being detachably screwed onto the screw ring around the central axis L.

[0020] Preferably, the inner surface of the cover is provided with a plurality of first engagement portions, and the outer surface of the engagement ring is provided with a plurality of second engagement portions. One of the first engagement portions and the second engagement portions includes an engagement limiting groove, and the other of the first engagement portion and the second engagement portion includes a limiting protrusion. During the engagement process, the limiting protrusion engages with the engagement limiting groove.

[0021] Preferably, the second engagement portion includes a baffle disposed radially thereon, the baffle being adapted to abut against the first engagement portion to indicate engagement in place.

[0022] The beneficial effects of this utility model are:

[0023] 1. By setting a track-limiting groove with a specific motion trajectory and a corresponding sliding column, the user only needs to press the button to the first braking position to trigger the exhaust sealing function; pressing the button harder to the second braking position will trigger the direct opening function, realizing the switching between the sealing and ventilating states of the sealed container without complicated operation steps, which greatly improves the convenience of use.

[0024] Second, thanks to the heart-shaped structure of the tracking groove, the sliding column can automatically lock into the corresponding locking position after different operations. The first locking position corresponds to the sealed state, and the second locking position corresponds to the open ventilation state. The mechanical locking provides a clear physical state indication.

[0025] Third, during the exhaust sealing operation, the valve plate body can effectively guide air out under pressure. When the button is released, the slide is locked in the first locking position, and the valve plate, under the combined action of the negative pressure inside the container and the spring, tightly fits the exhaust channel, forming a self-reinforcing seal, which significantly improves long-term sealing reliability and reduces the risk of leakage.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0035] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0036] like Figure 1-6 The aforementioned switch structure for a sealed container includes an actuation component, a transmission component, a switch body 200, and a valve plate 500. The actuation component includes a button 101 and a spring 102. The transmission component includes a slide column 103 disposed on the button 101. The switch body 200 includes an exhaust channel 203 and a tracking groove. The exhaust channel 203 is adapted to connect to the exhaust channels 203 inside and outside the sealed container. The slide column 103 can move unidirectionally within the tracking groove. The tracking groove has a heart-shaped structure. The tracking groove includes a second locking position 402, a second sliding guide portion 422, a first stroke groove 403, a first braking position 405, a first sliding guide portion 411, a first locking position 401, a first sliding guide portion 412, a second braking position 406, a second stroke groove 404, a second sliding guide portion 421, and a second locking position 402, connected sequentially along the movement direction of the slide column 103. The valve plate 500 is adapted to seal the exhaust passage 203, and the spring 102 abuts against the button 101 and the valve plate 500.

[0037] The process of achieving air extraction and sealing by pressing button 101 once is as follows: Button 101 is adapted to drive the slide column 103 from the second locking position 402 through the second sliding guide part 422 and the first stroke groove 403 to the first braking position 405. The spring 102 is then compressed, and the valve plate 500 is compressed to squeeze out part of the air in the sealing container and seal the exhaust channel 203 to form a negative pressure space. After the external force is removed, the spring 102 is adapted to drive the slide column 103 to move to the first locking position 401 under the guidance of the first sliding guide part 411. At this time, the valve plate 500 maintains the seal of the exhaust channel 203.

[0038] The process of ventilating by pressing button 101 once is as follows: Button 101 is adapted to drive the slide column 103 to move from the first locked position 401 to the second braking position 406 under the guidance of the first sliding guide 412. The spring 102 is compressed accordingly, and at this time the valve plate 500 keeps the exhaust passage 203 sealed. After the external force is removed, the spring 102 is adapted to drive the slide column 103 to move through the second forming groove and the second sliding guide 421 to restore the locking engagement with the second locked position 402. At this time, the exhaust passage 203 is opened.

[0039] In this embodiment, the switch body 200 includes a base 201 and three surrounding plates 202, the surrounding plates 202 being arc-shaped plates. An exhaust channel 203 is formed at the center of the base 201, and a tracking groove is formed in the surrounding plates 202. A central axis L is defined, adapted to pass through the center of the base 201 and be perpendicular to the base 201, and the surrounding plates 202 are evenly distributed circumferentially around the central axis L. The first locking position 401, the second locking position 402, the first braking position 405, and the second braking position 406 all include arc-shaped surfaces adapted to fit the shape of the sliding column 103. The first travel groove 403 is arranged along the direction of the central axis L, and the second travel groove 404 is arranged along the direction of the central axis L, simplifying part of the movement trajectory.

[0040] In this embodiment, the button 101 includes a pressure-bearing top plate 111, a peripheral wall 112 surrounding the pressure-bearing top plate 111, and a plurality of support plates 113 extending downward from the peripheral wall 112. The sliding column 103 protrudes from the support plate 113 and is evenly distributed around the central axis L.

[0041] In this embodiment, the valve plate 500 includes a valve plate body 501 and a support column 502 supported below the valve plate body 501. A support sleeve 204 suitable for supporting the support column 502 is formed in the center of the exhaust channel 203. The valve plate body 501 is suitable for completely covering the exhaust channel 203. The valve plate body 501 is trumpet-shaped or spherical in its natural state. The valve plate body 501 includes an open end and a constricted end. The open end is set towards the button 101. This design is beneficial for the valve plate body 501 to effectively gather and guide the air flow below to the exhaust channel 203 during the pressurized exhaust stage, accelerate the air discharge, promote the rapid formation of negative pressure space in the container, optimize the vacuum effect, and at the same time, the reset tendency of the valve plate body 501 is conducive to the smooth reopening of the exhaust channel 203.

[0042] In this embodiment, the spring 102 abuts against the valve plate body 501 via a pressure transmitting member 600. The pressure transmitting member 600 includes a pressure transmitting plate 601 and several cantilever 602 connected to the pressure transmitting plate 601. The cantilever 602 is connected to the base 201 to support the pressure transmitting plate 601, and the pressure transmitting plate 601 presses against the valve plate body 501. The button 101 includes a first limiting groove 114 extending downward from the inner surface of the pressure-bearing top plate 111. The first limiting groove 114 is adapted to receive one end of the spring 102. A second limiting groove 611 is formed on the upper surface of the pressure transmitting plate 601. Both ends of the spring 102 are respectively received in the first limiting groove 114 and the second limiting groove 611. A pressure ring 612 extends downward from the lower surface of the pressure transmitting plate 601 and presses against the valve plate body 501. This design effectively limits the position of the spring 102 and the valve plate 500, ensuring accurate force transmission path and reliable operation. The radial dimension of the pressure ring 612 is smaller than that of the exhaust passage 203.

[0043] In this embodiment, the switch body 200 also includes several reinforcing ribs 205 supported below the exhaust channel 203. The reinforcing ribs 205 are arranged radially, and the support sleeve 204 is disposed in the center of the reinforcing ribs 205.

[0044] In this embodiment, the switch structure further includes a cover 300 adapted to cover the enclosure 202. The cover 300 includes a clearance opening 301 that allows the button 101 to extend and retract. The switch body 200 includes an annular support plate 206 and a screw ring 207. The annular support plate 206 is adapted to support the cover 300. The cover 300 and the screw ring 207 are detachably screwed together around the central axis L. Specifically, the inner surface of the cover 300 is provided with a plurality of first screw portions 302, and the outer surface of the screw ring 207 is provided with a plurality of second screw portions 208. The first screw portions 302 include a limiting protrusion 321, and the second screw portions 208 include a screw-in limiting groove 281. During the screwing process, the limiting protrusion 321 engages with the screw-in limiting groove 281. The second screw portions 208 include a baffle 282 arranged radially thereon, which is adapted to abut against the first screw portions 302 to indicate that the screwing is in place.

[0045] In summary, this switch structure, through innovative heart-shaped tracking groove trajectory control, optimized valve plate design and negative pressure sealing mechanism, and highly integrated circumferential layout, successfully achieves core objectives such as simplified operation, reliable state locking, improved sealing performance, and compact and stable structure, providing a highly efficient, reliable, and user-friendly switch solution for sealed containers.
