In some embodiments, as shown in fig. 2, the operating exhaust linkage 400 includes an operating portion 410 and an exhaust lever 420, the exhaust lever 420 is driven between the operating portion 410 and the exhaust device 200, and the operating portion 410 is adapted to control the exhaust lever 420 such that the exhaust lever 420 triggers the exhaust device 200 to open.

Further, as shown in fig. 2, the automatic exhaust linkage 300 is coupled to the exhaust lever 420 and is adapted to control the exhaust lever 420 such that the exhaust lever 420 triggers the exhaust 200 to open.

More specifically, as shown in fig. 1 and 2, the structure of the exhaust device 200 is schematically illustrated in a closed state; in this state, the automatic exhaust link mechanism 300 is not triggered, and it is understood that the operation exhaust link mechanism 400 is not operated. At this time, the exhaust lever 420 is in an initial state, and the exhaust apparatus 200 is not triggered to open. It is understood that the exhaust device 200 may be controlled to be opened by operating any one of the exhaust linkage 400 and the automatic exhaust linkage 300 based on the present state, as needed.

Fig. 3 is a schematic structural view of the exhaust apparatus 200 in an open state; in this state, the automatic exhaust linkage 300 is triggered, and the push rod 310 (driven member) of the automatic exhaust linkage 300 is pushed up, which can be specifically understood as shown in fig. 3. At this time, the exhaust rod 420 is driven by the automatic exhaust linkage 300 to be in a working state, and the exhaust rod 420 triggers the exhaust device 200 to open.

As shown in fig. 3, in this state, the operation exhaust link mechanism 400 is not operated. Of course, it will be appreciated that the present design also allows the exhaust linkage 400 to be operated in the present state to the position where it is operated to control the opening of the exhaust device 200, and the power of the exhaust linkage 400 and the automatic exhaust linkage 300 will not interfere and cancel each other. That is, in this state, the user presses the operation portion 410 without disturbing the exhaust state of the exhaust device 200.

Through the structure of this embodiment, realized borrowing exhaust rod 420 of operation exhaust mechanism and reached the automatic exhaust transmission purpose, do benefit to and retrench product spare part quantity for product structure is simplified, cost reduction. And through this structural design for realize the integration between operation exhaust link gear 400 and the automatic exhaust link gear 300, like this, exhaust apparatus 200's cooperation target and cooperation relation are simplified, in other words, carry out automatic exhaust or manual exhaust and all realize control through exhaust pole 420 to exhaust apparatus 200 drive, like this, exhaust apparatus 200 department is difficult to appear influences such as interference, and exhaust apparatus 200's response precision is higher, and control accuracy is better.

In certain embodiments, as shown in FIG. 2, the automatic exhaust linkage 300 includes a push rod 310. When the push rod 310 is triggered, the push rod 310 is linked with the exhaust lever 420 and the exhaust device 200 is opened through the exhaust lever 420.

The push rod 310 is matched with the driving member, so that the automatic exhaust linkage mechanism 300 serves as a bridge between the driving member and the exhaust device 200, and the driving member controls the opening and closing of the exhaust device 200. The push rod 310 can be triggered by the driving piece on the cooker body to correspondingly control the exhaust device 200 to open, which can realize good automatic exhaust control for the split cooker, so that the cooking modes are more diversified. And has the advantages of simple structure and low cost.

And the driving member triggers the push rod 310 to correspondingly control the opening of the exhaust device 200, the form of the driving member that can be matched has diversity, that is, it is enough to trigger the push rod 310, for example, it is enough to drive the push rod 310 (such as pressing, pushing or rotating the push rod 310), so that the adaptability between the lid body 10 and the cooker body with different driving members is stronger, which is more beneficial to the popularization and application of the product and the reduction of the product cost.

In some embodiments, as shown in fig. 2, further, a transmission member (which can be understood by referring to the transmission lever 320 shown in fig. 1 to 3) is disposed between the push rod 310 and the exhaust rod 420, and the push rod 310 and the exhaust rod 420 are transmitted via the transmission member; when the push rod 310 is triggered, the push rod 310 links the exhaust device 200 to open the exhaust device 200. The transmission member is used for transmission between the push rod 310 and the exhaust rod 420, so that the transmission member can form bridging or transition between the push rod 310 and the exhaust rod 420, is more beneficial to the integrated design and the position layout between the automatic exhaust linkage mechanism 300 and the operation exhaust linkage mechanism 400, and can absorb, absorb and damp the vibration between the push rod 310 and the exhaust rod 420 to a certain extent.

Of course, the present solution is not limited to this, and a transmission member may not be provided. For example, in other embodiments, the engagement between the push rod 310 and the exhaust rod 420 is used.

Of course, the present solution is not limited to this, and the push rod 310 may not be provided to form a cooperative transmission with the driving member. For example, in other embodiments, the coupling power supply between the cover 10 and the cooker body can also be designed to realize automatic exhaust control by using electric control. Specifically, for example, a first coil is disposed on the cooker body, a second coil and an electric driving element are disposed on the lid body 10, the first coil and the second coil are coupled to supply power to the electric driving element, and the exhaust device 200 is correspondingly controlled to open and close after the electric driving element is powered on, so as to achieve automatic exhaust control.

In some embodiments of this embodiment, as shown in FIG. 2, further, the transmission member includes a transmission lever 320; wherein, the transmission lever 320 is rotatably connected with the cover body 100, and the transmission lever 320 is matched with the push rod 310 and the exhaust rod 420 and transmits between the push rod 310 and the exhaust rod 420. The length of the driving arm of the driving lever 320 can be controlled to correspondingly adjust the magnitude relationship and the position relationship of the driving force between the push rod 310 and the exhaust rod 420, which is more beneficial to fine adjustment of the cover 10 on various products, for example, the length of the driving arm of the driving lever 320, the proportion of the driving lever 320 and/or the matching positions of the driving lever 320, the push rod 310 and the exhaust rod 420 can be adjusted to fine adjust, so that the cover 10 can have better compatibility when being applied among different products, the universality and the standard property of the product structure are improved, and the product adaptability is stronger.

Further, as shown in fig. 10, the transmission lever 320 has a first transmission arm 321 and a first connection portion 322; the first connecting portion 322 is rotatably connected with the cap body 100. The push rod 310 and the exhaust rod 420 are engaged with the first transmission arm 321, respectively. Therefore, the consistency of the movement direction between the push rod 310 and the exhaust rod 420 is better, which is beneficial to saving transmission size chains and improving transmission efficiency and reliability. The structure can ensure that the matching precision of the transmission lever 320, the push rod 310 and the exhaust rod 420 is more guaranteed, the transmission precision of the transmission lever 320 is higher, and therefore the automatic exhaust control precision is improved.

For example, as shown in fig. 3, the driving member drives the push rod 310 to move upward, the push rod 310 correspondingly drives the first transmission arm 321, so that the first transmission arm 321 swings upward around the first connection portion 322, and the first transmission arm 321 drives the exhaust rod 420 to swing upward by swinging upward, wherein the exhaust rod 420 jacks up the exhaust valve 220 of the exhaust device 200 during swinging upward, so that the exhaust channel 210 originally sealed by the exhaust valve 220 is switched from closed to open. In the present structure, when the push rod 310 is driven upward by the driving member, the push rod 310, the first transmission arm 321 of the transmission lever 320, the exhaust rod 420 and the exhaust valve all move upward. The motion consistency is better, and this structure can compromise when guaranteeing the direction consistency and make to have higher transmission precision between exhaust rod 420 and the push rod 310 to promote automatic exhaust control precision.

Of course, the present embodiment is not limited thereto, and in other embodiments, the portion of the actuating lever 320 for engaging with the push rod 310 and the portion of the actuating lever 320 for engaging with the exhaust rod 420 may be disposed at both sides of the first connecting portion 322. So that the direction of movement between the push rod 310 and the exhaust rod 420 is reversed.

Alternatively, in other embodiments, two actuator arms may be designed, one of which is used to cooperate with the push rod 310 and the other of which is used to cooperate with the exhaust rod 420, as desired. The two driving arms may be located on the same side of the first connecting portion 322, so that the moving directions between the push rod 310 and the exhaust rod 420 are the same, such as both upward or both downward. Alternatively, two actuator arms may be positioned at both sides of the first connection portion 322 such that the movement direction between the push rod 310 and the exhaust rod 420 is opposite.

Further, as shown in fig. 10, with respect to the first transmission arm 321, a portion thereof for engaging with the exhaust rod 420 is located between the first connection portion 322 and a portion thereof for engaging with the push rod 310. It can also be understood that the distance from the first connection portion 322 to the portion of the first transmission arm 321 for engaging with the exhaust rod 420 is shorter than the distance from the first connection portion 322 to the portion of the first transmission arm 321 for engaging with the push rod 310. This can save the driving force of the push rod 310 and improve the response accuracy of the exhaust device 200, so that the push rod 310 can be more easily opened in conjunction with the exhaust device 200, and the exhaust device 200 can have higher response timeliness and accuracy for the linkage between the push rod 310 and the exhaust device 200, thereby improving the automatic exhaust control accuracy.

In more detail, for example, the first transmission arm 321 has a transition arm 3213 and an extension arm 3214, the transition arm 3213 engages the extension arm 3214 and the transition arm 3213, the transition arm 3213 is engaged with the exhaust rod 420, and the extension arm 3214 is engaged with the push rod 310.

In some embodiments, as shown in fig. 10, the first connecting portion 322 includes a rotating shaft 3222, and the cover body 100 is provided with a second mounting seat 142, more specifically, the face cover 101 of the cover body 100 is provided with a second mounting seat 142, wherein the second mounting seat 142 is provided with a hole, and the rotating shaft 3222 extends into the hole and is rotatable relative to the second mounting seat 142, so as to implement the rotational connection between the transmission lever 320 and the cover body 100.

Further, as shown in fig. 10, the first connecting portion 322 further includes a connecting body 3221, and two opposite sides of the connecting body 3221 are respectively provided with a rotating shaft 3222. As shown in fig. 11, the second mounting seat 142 specifically includes two oppositely disposed lugs, the two lugs are respectively provided with a hole, the connecting body 3221 is located between the two lugs, and the two rotating shafts 3222 correspondingly extend into the respective holes of the two lugs to implement the assembly.

In some embodiments, as shown in fig. 10, the first transmission arm 321 has a transition arm 3213 and an extension arm 3214, the transition arm 3213 engages the extension arm 3214 and the transition arm 3213, and a turning transition 3215 is formed between the transition arm 3213 and the extension arm 3214, the transition arm 3213 is adapted to cooperate with the push rod 310, and the extension arm 3214 is adapted to cooperate with the exhaust rod 420. Therefore, the transition arm 3213 and the exhaust rod 420 can be avoided, and the interference of the movement of the exhaust rod 420 caused by the stroke of the transition arm 3213 is small, so that the transmission precision between the transmission lever 320 and the exhaust rod 420 can be further improved, and the automatic exhaust control precision is improved.

In more detail, as shown in fig. 10, a turning transition 3215 is formed between the transition arm 3213 and the extension arm 3214, and specifically, an included angle transition or a fillet transition is formed between the transition arm 3213 and the extension arm 3214, so that a certain included angle is formed between the transition arm 3213 and the extension arm 3214, which not only enhances the rigidity of the transmission lever 320, but also facilitates avoiding between the transition arm 3213 and the exhaust rod 420, and improves the transmission accuracy between the transmission lever 320 and the exhaust rod 420.

Further, as shown in fig. 10, a protruding direction of the rotating shaft 3222 of the first connecting portion 322 from the connecting body 3221, or an axial direction of the rotating shaft 3222, is substantially along an extending direction of the transition arm 3213, and forms an included angle with the extending arm 3214, so that the load distribution of the transmission lever 320 is more optimized, and the avoiding effect between the transition arm 3213 and the exhaust rod 420 is better.

In some embodiments, one of the actuating lever 320 and the cover body 100 is provided with a guide protrusion 324, the other is provided with a guide groove 110, the guide protrusion 324 protrudes into the guide groove 110, and the actuating lever 320 rotates such that the guide protrusion 324 moves along the guide groove 110. On one hand, the assembly and positioning of the transmission lever 320 are convenient, and on the other hand, the problem of deflection and deviation is not easy to occur in the motion process of the transmission lever 320, so that the matching precision of the transmission lever 320, the push rod 310 and the exhaust rod 420 can be better guaranteed, the separation is prevented, and the transmission reliability and precision of the transmission lever 320 between the exhaust rod 420 and the push rod 310 are guaranteed.

For example, the cover body 100 is provided with a guide slot 110, and more specifically, the face cover 101 of the cover body 100 is provided with a guide slot 110, and the transmission lever 320 is provided with a guide protrusion 324.

As shown in fig. 11, the guide groove 110 on the surface cover 101 may be formed by surrounding a rib on the surface cover 101, and the rib protrudes from the surface of the surface cover 101 to surround the guide groove 110, so that the thickness of the surface cover 101 does not need to be increased, and the product molding quality is better and the material is saved.

Further, as shown in fig. 11, the rib specifically includes two barrier ribs 111, and the two barrier ribs 111 are disposed opposite to each other and spaced apart to define the guide groove 110. Further, the ribs 112 are formed on the opposite surfaces of the two barrier ribs 111, and one or more ribs 112 are formed on the surfaces of the two barrier ribs 111, so that the friction area between the guide protrusion 324 and the guide groove 110 can be reduced, and thus, the transmission lever 320 is less resistant.

As shown in fig. 11, a side opening 113 is formed at an end position of the extending direction of the barrier rib 111 between the two barrier ribs 111, so that when the driving lever 320 rotates to make the guide protrusion 324 perform arc motion, the guide protrusion 324 does not interfere with the guide groove 110, the motion reliability is better, and the design makes the assembly tolerance allowance between the driving lever 320 and the surface cover 101 larger, the driving lever 320 is not easy to be jammed, and the product yield is higher.

Further, as shown in fig. 10, two oppositely distributed ribs are protruded from the surface of the transmission lever 320, and the two ribs define a guide protrusion 324. Such a structure makes the guide protrusion 324 substantially hollow, which is advantageous for reducing the weight of the transmission lever 320, so that the transmission loss of the product is lower, and the transmission precision is also more advantageous for handling.

In some embodiments, as shown in fig. 10, the guide protrusion 324 is disposed on the extension arm 3214 of the actuating lever 320, such that the guide protrusion 324 has a certain distance from the first connection portion 322, the guide protrusion 324 has a greater amount of movement, the guiding performance of the guide engagement with the guide slot 110 is better, and the guide protrusion 324 is not easily jammed with the guide slot 110.

In some embodiments, the automatic exhaust linkage 300 further includes a second return elastic member 332, and the second return elastic member 332 is engaged with the actuating lever 320, wherein when the push rod 310 is triggered, the actuating lever 320 links the exhaust device 200 to open the exhaust device 200, and the actuating lever 320 deforms the second return elastic member 332.

By providing the second elastic return element 332, when the push rod 310 is triggered, the push rod 310 drives the transmission lever 320, so that the transmission lever 320 is linked with the exhaust rod 420 to correspondingly control the exhaust rod 420 to open the exhaust device 200, and simultaneously, the transmission lever 320 deforms the second elastic return element 332, at this time, the second elastic return element 332 stores energy through deformation. When the push rod 310 is not triggered, the elastic restoring force of the second restoring elastic member 332 is utilized to drive the transmission lever 320 to automatically restore, so that the transmission of the transmission lever 320 between the push rod 310 and the exhaust rod 420 is facilitated next time, and simultaneously, the linkage effect of the transmission lever 320 on the exhaust device 200 can be correspondingly removed, so that the exhaust device 200 can restore to the closed state, the sealing reliability is ensured, meanwhile, the restoring action of the transmission lever 320 is automated, and the use and operation of the product are simplified.

For example, the second elastic restoring member 332 may be embodied as a spring, a spring sheet, an elastic body (e.g., elastic rubber, silicon rubber, etc.), and in this case, the second elastic restoring member 332 may be engaged and driven by abutting against the driving lever 320.

Of course, the present invention is not limited thereto, and in some embodiments, the second return elastic member 332 may be a pair of magnets having the same magnetic pole, and the driving lever 320 may be elastically driven by the mutual repulsive force between the magnets, in which case, one of the magnets is disposed on the driving lever 320 to perform driving, or the driving lever 320 itself serves as one of the opposite magnetic poles.

Furthermore, a limiting portion 325 is disposed on the transmission lever 320, and the limiting portion 325 is engaged with the second elastic return member 332 of the automatic exhaust linkage mechanism 300, so that the engaging position between the second elastic return member 332 of the automatic exhaust linkage mechanism 300 and the transmission lever 320 is fixed. Thus, on the one hand, the length of the transmission arm between the second reset elastic piece 332 and the transmission lever 320 is relatively stable, so that the transmission precision of the transmission lever 320 between the push rod 310 and the exhaust rod 420 is higher, the transmission is more stable, and the automatic exhaust process is more reliable, on the other hand, the assembly and the positioning between the transmission lever 320 and the second reset elastic piece 332 are more convenient, the matching between the transmission lever 320 and the second reset elastic piece 332 is more stable and reliable, and the automatic reset function of the transmission lever 320 is more reliable.

For example, as shown in fig. 10, the transmission lever 320 is provided with a convex hull as the limiting portion 325. The second return elastic member 332 includes a spring, one end of which abuts against the actuating lever 320 and is sleeved outside the convex hull, so as to limit the relative dislocation of the spring on the surface of the actuating lever 320.

Of course, in other embodiments, the groove can be used as the limiting portion 325, so that one end of the spring is embedded into the groove to realize positioning and limiting.

In certain embodiments, the cap body 100 has a face cap 101. The driving lever 320 is rotatably connected with the face cover 101. The second return elastic member 332 is disposed between the transmission lever 320 and the face cover 101.

For example, the second return elastic member 332 is a spring, one end of which abuts against the face cover 101, and the other end of which abuts against the transmission lever 320. Thus, the installation and the reset driving of the transmission lever 320 are integrated on the face cover 101, and the driving reset precision and the reliability of the transmission lever 320 are higher, so that the assembly of a product is more convenient.

Further, as shown in fig. 11, a limiting groove 120 is provided on the face cover 101, and one end of the spring, which is used for being engaged with the face cover 101, extends into the limiting groove 120 and is limited by the limiting groove 120.

In some embodiments, as shown in fig. 2, the automatic exhaust linkage mechanism 300 further includes a first elastic return element 331, and the first elastic return element 331 is engaged with the push rod 310, wherein when the push rod 310 is triggered, the push rod 310 links the exhaust device 200 to open the exhaust device 200, and the push rod 310 deforms the first elastic return element 331.

Through setting up first elastic component 331 that resets, when push rod 310 is triggered, push rod 310 linkage exhaust apparatus 200 opened the time, push rod 310 makes first elastic component 331 take place the deformation, and at this moment, first elastic component 331 that resets carries out the energy storage through deformation. When the push rod 310 is not triggered, the elastic restoring force of the first restoring elastic member 331 is utilized to drive the push rod 310 to automatically restore, so as to facilitate the next triggering of the push rod 310, and simultaneously, the linkage effect of the push rod 310 on the exhaust device 200 can be correspondingly removed, so that the exhaust device 200 can restore to the closed state, thereby ensuring the sealing reliability, and simultaneously, the restoring action of the push rod 310 is automated, thereby simplifying the use and operation of the product.

For example, the first elastic return element 331 may be embodied as a spring, a leaf spring, an elastic body (such as elastic rubber, silicon rubber, etc.), and in this case, the first elastic return element 331 may be engaged and driven by abutting against the push rod 310.

Of course, the present invention is not limited thereto, and in some embodiments, the first return elastic member 331 may be a pair of magnets having the same magnetic pole, and the pushing rod 310 may be elastically driven by using the mutual repulsive force between the magnets, in which one of the magnets is disposed on the pushing rod 310 to realize transmission, or the pushing rod 310 itself serves as one of the opposite magnetic poles.

Furthermore, as shown in fig. 2, a protruding point 316 is disposed on the push rod 310, and the protruding point 316 cooperates with the first elastic restoring member 331, so that the cooperating position between the first elastic restoring member 331 and the push rod 310 is fixed. Like this, on the one hand, make the transmission arm length between first elastic component 331 that resets and the push rod 310 relatively stable, thereby make the push rod 310 transmission precision between transmission lever 320 and driving piece higher, the transmission is more stable, push rod 310 also is difficult for appearing deflecting the aversion scheduling problem, thereby make the automatic exhaust process more reliable, on the other hand, make the positioning between push rod 310 and the first elastic component 331 that resets more convenient, and make the cooperation between push rod 310 and the first elastic component 331 that resets more reliable, thereby make push rod 310 automatic re-setting function more reliable.

For example, as shown in fig. 2, the push rod 310 is provided with a bump 316. The first return elastic member 331 includes a spring, one end of which abuts against the push rod 310 and is sleeved outside the convex point 316, so as to limit relative dislocation of the spring on the surface of the push rod 310.

Of course, in other embodiments, a groove may be used instead of the protrusion 316, and one end of the spring may be inserted into the groove to position and limit the push rod 310.

In certain embodiments, as shown in fig. 2, the cover body 100 has a side cover 102. The side cover 102 has a side wall 1021 and an upper rim 1022, and the upper rim 1022 is provided at the top end of the side wall 1021. The push rod 310 is located inside the sidewall 1021. The first elastic return element 331 is disposed between the push rod 310 and the upper edge 1022.

For example, the first return elastic member 331 is a spring, one end of which abuts against the upper side edge 1022, and the other end of which abuts against the push rod 310. Further, as shown in fig. 2, a guide post 1023 is provided on the upper side edge 1022, and one end of the spring for cooperating with the upper side edge 1022 is fitted around the outer side of the guide post 1023.

In some embodiments, the push rod 310 is movably connected with the cap body 100; the cover body 100 is provided with a guide structure, which is engaged with the push rod 310 and guides the movement of the push rod 310. On one hand, the assembly positioning effect between the push rod 310 and the cover body 100 is achieved, the assembly precision between the push rod 310 and the transmission part (such as the transmission lever 320) can be better ensured, and even the assembly precision between the push rod 310 and the driving part on the cooker body is ensured, so that the automatic exhaust control precision is improved.

As described above, by providing the transition arm 3213 including the first sub-arm 32131 and the second sub-arm 32132, and using the second sub-arm 32132 to transition between the extension arm 3214 and the first sub-arm 32131, the position and distribution relationship of the extension arm 3214 relative to the ground-first connection portion 322 can be more flexibly adjusted according to the requirement, so that the transmission lever 320 and the exhaust rod 420 can be more reasonably arranged and avoided, and while the linkage between the transmission lever 320 and the exhaust rod 420 is satisfied, the interference caused by the stroke of the transmission lever 320 on the movement of the exhaust rod 420 can be better reduced, thereby further improving the transmission accuracy between the transmission lever 320 and the exhaust rod 420, improving the automatic exhaust control accuracy, and realizing higher flexibility and adjustability of the layout design between the components through the structure, thereby enabling better distribution rationality and compatibility between the internal components of the product, the space waste is avoided, and the size of the product is reduced.

In certain further embodiments, a turning transition 3216 is formed between the first and

second sub-arms

32131, 32132.

In certain further embodiments, a turning transition 3215 is formed between the first sub-arm 32131 and the extension arm 3214.

Through the above, the position of the second sub-arm 32132, or even the position of the extension arm 3214, can be allocated to the position on the side of the center line of the first connection portion 322 through the transition arm 3213, and in addition, the second sub-arm 32132 is combined with the exhaust rod 420 or the position of the first sub-arm 32131 corresponding to the second sub-arm 32132 is combined with the exhaust rod 420, so that the extension arm 3214 effectively avoids the exhaust rod 420 while the exhaust rod 420 is in transmission fit with the transmission lever 320, and thus, the interference of the movement of the exhaust rod 420 by the stroke of the transmission lever 320 is small, thereby further improving the transmission accuracy between the transmission lever 320 and the exhaust rod 420 and improving the automatic exhaust control accuracy.

Specifically, for example, a turning transition 3216 is formed between the first sub-arm 32131 and the second sub-arm 32132, and specifically, an included angle transition or a fillet transition is formed between the first sub-arm 32131 and the second sub-arm 32132, so that a certain included angle is formed between the first sub-arm 32131 and the second sub-arm 32132, which not only enhances the rigidity of the transmission lever 320, but also facilitates avoiding between the transition arm 3213 and the exhaust rod 420, and improves the transmission accuracy between the transmission lever 320 and the exhaust rod 420.

Specifically, for example, a turning transition 3215 is formed between the first sub-arm 32131 and the extension arm 3214, and specifically, an included angle transition or a fillet transition is formed between the second sub-arm 32132 and the extension arm 3214, so that a certain included angle is formed between the second sub-arm 32132 and the extension arm 3214, which not only enhances the rigidity of the transmission lever 320, but also facilitates avoiding between the transition arm 3213 and the exhaust rod 420, thereby improving the transmission accuracy between the transmission lever 320 and the exhaust rod 420.

In certain further embodiments, as shown in FIG. 12, the exhaust stem 420 has a second connecting portion 424. As shown in fig. 16, the second connecting portion 424 is rotatably connected to the cap body 100. Thereby achieving the rotational coupling between the exhaust rod 420 and the cap body 100.

As shown in fig. 16, the distance between the center line x1 of the second connection portion 424 and the center line x3 of the first connection portion 322 is zero. That is, referring to fig. 16 in detail, the center line x1 of the second connecting portion 424 and the center line x3 of the first connecting portion 322 are shown in a coincident relationship in the drawing to indicate that the distance between the center line x1 of the second connecting portion 424 and the center line x3 of the first connecting portion 322 is zero. Therefore, the loss of the transmission position of the transmission lever 320 to the exhaust rod 420 in the power transmission process can be avoided, the transmission process is more efficient, the transmission structure has higher stability, and the transmission of the transmission lever 320 to the exhaust rod 420 is more accurate and reliable.

Of course, the above is only a preferred technical solution of the present design, and in other embodiments, when the distance S1 (not shown in the figures) between the center line x1 of the second connecting portion 424 and the center line x3 of the first connecting portion 322 is greater than zero, the distance S1 between the center line x1 of the second connecting portion 424 and the center line x3 of the first connecting portion 322, and the distance S2 between the center line x2 of the extension arm 3214 and the center line x3 of the first connecting portion 322 may be designed as required to satisfy: the ratio of S1 to S2 is greater than 0 and equal to or less than 0.5. Specifically, the ratio of S1/S2 is, for example, 0.1, 0.2, 0.3, 0.4, or the like. By controlling the ratio of S1/S2 to be greater than 0 and less than or equal to 0.5, the loss from the transmission position of the transmission lever 320 to the exhaust rod 420 in the power transmission process can be effectively reduced, and the stability of the transmission structure can be better ensured, so that the transmission of the transmission lever 320 to the exhaust rod 420 is more accurate and reliable.

It should be noted that the center line x1 of the second connecting portion 424 may be understood as a perpendicular bisector of a connecting line between two ends of the second connecting portion 424 in the width direction, and of course, the center line x1 of the second connecting portion 424 may be specifically understood as a perpendicular bisector of a connecting line between two points at the farthest distance between two engaging lugs on the second connecting portion 424.

In certain further embodiments, as shown in fig. 16, the cap body 100 has a face cap with a first mounting seat 141, and the exhaust rod 420 is rotatably coupled to the first mounting seat 141. In this regard, to further facilitate accurate understanding and grasp of the center line x1 of the second connection portion 424, those skilled in the art may also equate the center line of the first mounting seat 141 with the center line x1 of the second connection portion 424 without conflict, based on the assembly of the first mounting seat 141 and the second connection portion 424.

In certain further embodiments, as shown in fig. 16, the centerline x1 of the second connection portion 424 is substantially parallel to the centerline x3 of the first connection portion 322.

For example, the center line x1 of the second connecting portion 424 is parallel to the center line x3 of the first connecting portion 322, but a certain angle (e.g., 0 ° to 30 °) between the center line x1 of the second connecting portion 424 and the center line x3 of the first connecting portion 322 may be allowed.

In certain further embodiments, as shown in fig. 15 and 16, the cap body 100 includes a face cap; the center line x1 of the second connection portion 424 coincides with the center axis o of the face cover. Of course, the present disclosure is not limited thereto, and in other embodiments, the distance between the central line x1 of the second connection portion 424 and the central axis o of the face cover may be designed according to specific requirements, and the distance may be a preset distance. It is understood that the preset distance may be set by those skilled in the art based on factors such as space layout requirements, and the like, and the preset distance is not limited and specifically illustrated herein, but falls within the protection scope of the present disclosure without departing from the design concept.

In certain further embodiments, as shown in fig. 15 and 16, the cap body 100 includes a face cap; the center line x3 of the first connection portion 322 coincides with the center axis o of the face cover. Of course, the present disclosure is not limited thereto, and in other embodiments, the distance between the central line x3 of the first connection portion 322 and the central axis o of the front cover may be designed according to specific requirements, and the distance may be a preset distance. It is understood that the preset distance may be set by those skilled in the art based on factors such as space layout requirements, and the like, and the preset distance is not limited and specifically illustrated herein, but falls within the protection scope of the present disclosure without departing from the design concept.

In certain further embodiments, as shown in fig. 16, the cap body 100 comprises a face cap. The center line x1 of the second connecting portion 424, the center line x3 of the first connecting portion 322, and the central axis o of the face cover coincide with each other. The beneficial effect of this structure is: the loss of the transmission displacement of the transmission lever 320 to the exhaust rod 420 during the transmission process can be avoided, and the stability of the transmission structure can be maintained.

Of course, as an alternative, the center lines x1 of the second connection portions 424 and the center lines x3 of the first connection portions 322 do not necessarily coincide, and may have the spacing S1. The distance between the center line x3 of the first connection portion 322 and the center line x2 of the extension arm 3214 is S2. The ratio of S1/S2 is designed to be in the range of 0.1-0.5. The beneficial effect of this structure is: the loss of the transmission displacement of the transmission lever 320 to the exhaust rod 420 during the transmission process can be greatly reduced, and the stability of the transmission structure can be maintained.

In certain further embodiments, as shown in fig. 16, a portion of the exhaust rod 420 is located between the face cover of the cover body 100 and the actuating lever 320 (specifically, the transition arm 3213 of the actuating lever 320).

In certain further embodiments, as shown in fig. 1, 2 and 3, the cap body 10 further comprises a push rod 310. The push rod 310 is matched with the transmission lever 320, when the push rod 310 is triggered, the push rod 310 is linked with the exhaust rod 420 through the transmission lever 320, and the exhaust rod 420 triggers the exhaust device 200 to be opened.

Specifically, the push rod 310 is engaged with the extension arm 3214, and the push rod 310 is fitted to a drive on the pot body.

More specifically, when the cover 10 is covered with the pot body, the push rod 310 is opposite to the driving member on the pot body. When the driving member triggers the push rod 310, the push rod 310 will touch the extension arm 3214 of the transmission lever 320, so that the transmission action of the transmission lever 320 causes the transition arm 3213 to lift the exhaust rod 420, at which time the exhaust rod 420 is forced to move and lift the exhaust valve 220 of the exhaust device 200 from the valve core, thereby controlling the opening of the exhaust valve 220 (for example, as shown in fig. 3). When the driving member no longer triggers the push rod 310, the push rod 310 and the transmission lever 320 are reset based on the first reset elastic member 331 and the second reset elastic member 332, respectively, the exhaust valve 220 falls by gravity, or the exhaust valve 220 falls by being driven by the reset member provided for the exhaust valve 220, so that the exhaust valve 220 falls back on the valve core again, and the control of the closing of the exhaust valve 220 is realized (for example, as shown in fig. 1 and 2).

In certain further embodiments, as shown in fig. 4 and 5, the cover 10 further includes an operating portion 410. The operating portion 410 is configured with the exhaust lever 420 and adapted to drive the exhaust lever 420 such that the exhaust lever 420 triggers the exhaust device 200 to open.

Specifically, the operation portion 410 may be specifically a button, for example.

Specifically, the operation portion 410 is engaged with the exhaust rod 420, and when the operation portion 410 is triggered, the operation portion 410 presses the end of the exhaust rod 420 far away from the exhaust device 200, at this time, the end of the exhaust rod 420 near the exhaust device 200 is tilted, and the exhaust valve 220 of the exhaust device 200 is lifted from the valve core, so as to control the exhaust valve 220 to be opened (for example, as shown in fig. 5). When the operating part 410 is no longer triggered, the exhaust valve 220 falls by gravity, or the exhaust valve 220 is driven to fall via a reset member provided for the exhaust valve 220, so that the exhaust valve 220 falls back onto the valve core again, and the exhaust valve 220 is controlled to be closed (for example, as shown in fig. 4).
