Description

Technical Field

[0001] The utility model relates to the technical field of valve body structures, in particular to a quick-release valve. Background Art

[0002] Various existing feeding modules generally circulate materials through a preset feeding channel. In order to be able to adjust and control the flow state of the material in the feeding channel, a valve structure is generally provided in the feeding module. The valve core of the valve structure moves in the feeding channel to achieve conduction, isolation and opening adjustment of the feeding channel. However, the existing valve structure is generally built into the feeding channel, or fixed to the feeding module by fixing methods such as screws. When the valve core needs to be removed for cleaning, it is inconvenient to disassemble and assemble. Especially when the number of screws is large, the difficulty of disassembly and assembly between the valve structure and the feeding module is greatly increased, and the disassembly and assembly time is prolonged, which reduces the use efficiency.

At this time, the liquid stored in the liquid storage container can flow to the liquid outlet channel via the liquid inlet channel, and with the help of the movable switching of the valve core, the liquid outlet state can be adjusted. When the two blocks need to be disassembled, the screw connection can be screwed out in the opposite direction, and the pressing part is driven away from the block and the two proximal surfaces are moved away from each other, so that the positions of the two blocks are quickly unlocked and moved away, and the valve core is driven out of the liquid outlet channel, which is helpful for subsequent cleaning, disassembly, replacement and other maintenance work of the valve core.

[0049] See also Figures 1 to 12 The utility model provides an embodiment of a quick-release valve. The quick-release valve comprises a liquid storage container 100, a valve body assembly 200, at least two blocks and a quick-release assembly 400. The liquid storage container 100 is used to store liquid; the valve body assembly 200 includes a valve core member 210; at least two blocks respectively have proximal surfaces 301 that are close to each other in the up-down direction, and a first side surface 302 connected to the front and / or rear side of the proximal surface 301, the proximal surface 301 of one of the two blocks is convexly provided with a valve core member 210, and the other is provided with a liquid outlet channel 321 in the up-down direction, and a liquid inlet channel 322 is extended to the left or right from the side wall of the liquid outlet channel 321, and the liquid inlet channel 322 is communicated with the liquid storage container 100, the two blocks are detachably connected, and when the two are engaged, the valve core member 210 is driven to extend into the liquid outlet channel 321 to conduct and block the liquid outlet channel 321; and when the two are detached, the valve core member 210 is driven to disengage from the liquid outlet channel 321, the two blocks are respectively a first block 310 and a second block 320, and the first block 310 of the first block 310 has a first The side surface 302 forms a first guide surface 313, and the first side surface 302 of the second block 320 is penetrated by a first screw hole 324 along the front-to-back direction; the quick-release assembly 400 includes a pressing piece 410 and a screw connection piece 420. When the two blocks are joined, the pressing piece 410 is jointly arranged on the first side surfaces 302 of the two blocks, and is correspondingly provided with a second guide surface 414 and a second screw connection hole 411. The screw connection piece 420 sequentially connects the first screw connection hole 324 and the second screw connection hole 411, so that during its screw connection process, the second guide surface 414 is driven to slide on the first guide surface 313, so that the pressing piece 410 can move closer to and away from the two blocks; wherein, in the direction in which the pressing piece 410 moves closer to the blocks along the front-to-back direction, the first guide surface 313 and / or the second guide surface 414 extend obliquely in a direction gradually away from the corresponding first screw connection hole 324 and / or the second screw connection hole 411 along the up-down direction.

[0050] In the technical solution provided by the utility model, when the two blocks are engaged, the valve core member 210 is driven to extend into the liquid outlet channel 321. It only needs to be screwed forward by operating the screw member 420. Under the mutual cooperation between the screw member 420 and the first screw hole 324 and the second screw hole 411, on the one hand, the two blocks can be initially limited in each direction; on the other hand, the screw member 420 can drive the second guide surface 414 to slide on the second guide surface 414, and the pressing member 410 is driven to approach the block to achieve the locking of the two blocks in the front-back direction in the engaged state; at the same time, the two proximal surfaces 301 are driven to approach each other and abut against each other, so as to achieve the locking of the two blocks in the upper and lower directions in the engaged state, and help the two blocks to be more compact and stable. At this time, the liquid stored in the liquid storage container 100 can flow to the liquid outlet channel 321 via the liquid inlet channel 322, and with the help of the active switching of the valve core member 210, the liquid outlet state can be adjusted. When the two blocks need to be detached, the screw connection 420 only needs to be screwed out in the opposite direction, and the pressing member 410 is driven away from the block and the two proximal surfaces 301 are moved away from each other, so that the positions of the two blocks are quickly unlocked and moved away, and the valve core member 210 is driven outward from the liquid outlet channel 321, which is helpful for subsequent maintenance work such as cleaning, disassembly and replacement of the valve core member 210. The solution provided by the utility model helps to simplify the disassembly and assembly between the two blocks and the valve body assembly 200, greatly improves the disassembly and assembly speed and accuracy, and helps to improve the user experience.

[0051] First of all, it should be noted that the descriptions of the up-down, left-right, and front-back directions in the above and following embodiments do not constitute any limitation on the orientation of the quick-release valve in actual application. Figures 1 to 12 The three-dimensional directions of the structure shown are substantially perpendicular to each other in the up-down direction, the left-right direction, and the front-back direction.

[0052] It can be understood that the components of the quick-release valve are generally divided into a valve body module, a liquid supply module and a quick-release assembly 400 according to their functions, and may also include a heating module. The quick-release assembly 400 is mainly used to realize convenient disassembly and assembly between the valve body module and the liquid supply module. Therefore, the valve body module includes a valve body assembly 200 and at least one block (which may be a first block 310 or a second block 320); the liquid supply module includes a liquid storage container 100 and at least one remaining block (which may be a second block 320 or a first block 310). For ease of understanding, in the following embodiments, the first block 310 is used as a block in the valve body module, and the second block 320 is used as a block in the liquid storage container 100 for illustration. And more specifically, the first block 310 is located above the second block 320. At this time, the proximal surface 301 of the first block 310 is also the upper surface of the first block 310 ; the proximal surface 301 of the second block 320 is also the lower surface of the second block 320 .

[0053] In view of this, for Figures 1 to 12 the provided structure:

[0054] The liquid storage container 100 generally presents as a cylindrical structure extending along the up-down direction, and a liquid storage cavity for storing liquid is formed inside it. The liquid supply port of the liquid storage cavity is arranged downward, which facilitates the liquid to spontaneously flow out through the liquid supply port by means of the gravity. Among them, the specific type of the liquid can be specifically set according to actual needs, and can be, but is not limited to, clear water, solution, colloid, etc.

[0055] The second block 320 is arranged below the liquid storage container 100. The second block 320 is provided with a liquid outlet channel 321 penetrating along the up-down direction. The liquid outlet channel 321 forms an insertion port 321b on the upper end surface (i.e., its proximal surface 301) of the second block 320. The liquid outlet channel 321 forms a liquid outlet 321a on the lower end surface of the second block 320. The second block 320 also extends from the side wall of the liquid outlet channel 321 towards the direction where the liquid storage container 100 is located (i.e., the left direction in the figure) to form a liquid inlet channel 322. The communication port 322b is formed at the connection of the liquid inlet channel 322 and the liquid outlet channel 321. The liquid inlet channel 322 penetrates the outer wall of the second block 320 to form a liquid inlet 322a. The liquid inlet 322a is directly or connected through a joint structure with the liquid supply port of the liquid storage container 100. Among them, when extending in the left direction, the liquid inlet channel 322 can be perpendicular to the liquid outlet channel 321. At this time, the liquid inlet 322a penetrates the left side surface of the second block 320; or the liquid inlet channel 322 can be inclined relative to the liquid outlet channel 321 and can be bent at least once. At this time, the liquid inlet 322a can be bent to penetrate the upper end surface of the second block 320. In this way, it is more convenient to realize the connection between the liquid supply port and the liquid inlet 322a when the liquid storage container 100 is arranged directly above the second block 320 vertically, and the liquid storage container 100 is stably supported on the second block 320.

[0056] Furthermore, since both the first block 310 and the liquid storage container 100 are arranged above the second block 320, the quick-release valve can further include a mounting member, and the mounting member is fixedly connected to the liquid storage container 100 and the first block 310, so that the liquid storage container 100 and the first block 310 are generally fixed in each direction.

[0057] Furthermore, in order to make the structure of the second block 320 more adaptable to be respectively docked with the liquid storage container 100 and the first block 310, specifically, the second block 320 includes a main block 320a corresponding to the first block 310 and a side block 320b corresponding to the liquid storage container 100. The main block 320a is provided with the above-mentioned liquid outlet channel 321, and the main block 320a and the side block 320b jointly are provided with the above-mentioned liquid inlet channel 322.

[0058] In addition, a receiving cavity 310a is formed inside the first block 310. An installation channel 310b penetrating the lower end surface (i.e., its proximal surface 301) of the first block 310 is provided at the bottom of the receiving cavity 310a. The valve body assembly 200 includes a movable spool member 210 and a driving mechanism 220 for driving the spool member 210 to move. Among them, the driving mechanism 220 is generally installed in the receiving cavity 310a. The spool member 210 is at least disposed in the installation channel 310b and at least partially extends outwards through the installation channel 310b. It can be understood that the driving mechanism 220 can drive the spool member 210 to perform telescopic movement in the up and down direction. Any power assembly that can achieve this purpose can constitute the specific structure of the driving mechanism 220 described in the present utility model, which will not be elaborated here.

[0059] In order to facilitate the stable installation of the spool member 210 in the installation channel 310b and also facilitate the stable installation of the spool member 210 after it extends into the liquid outlet channel 321 through the insertion port 321b, the valve body assembly 200 may further include a docking member 230. The docking member 230 is generally cylindrical. Its outer wall is fixedly connected to the inner wall of the installation channel 310b. After being inserted into the liquid outlet channel 321, the outer wall of the docking member 230 is fixedly inserted into the inner wall of the channel section of the liquid outlet channel 321 at the corresponding position. A through hole is vertically penetrated inside the docking member 230, and the through hole allows the spool member 210 to move up and down. Of course, according to actual needs, sealing structures or elastic adaptor blocks and other structures can be selectively provided between the docking member 230 and the installation channel 310b, between the docking member 230 and the liquid outlet channel 321, between the docking member 230 and the driving mechanism 220, etc., to optimize the overall installation.

[0060] It can be understood that after extending into the liquid outlet channel 321, the spool member 210 can directly act on the liquid outlet 321a of the second block 320. For example, when the spool member 210 moves upward away from the liquid outlet 321a and continues to move up and down away from the communication port 322b, the liquid inlet channel 322 and the liquid outlet channel 321 are communicated through the communication port 322b. The liquid in the liquid storage container 100 can flow through the liquid inlet channel 322 to the liquid outlet channel 321 in sequence and is finally discharged outwards through the liquid outlet 321a; conversely, when the spool member 210 moves downward close to and covers the liquid outlet 321a (it can also be covering the communication port 322b), the liquid in the liquid storage container 100 cannot be discharged outwards through the liquid outlet 321a.

[0061] Or as Figures 1 to 5As shown, as needed, a boss 329 is convexly provided on the lower end surface of the second block 320 around the periphery of the liquid outlet 321a. The boss 329 is provided with an external thread. The quick-release valve also includes a nozzle 710, a nut 720 and a pressing block 730. Among them, the nozzle 710 is arranged at the liquid outlet 321a. The nut 720 is sleeved on the outer side of the boss 329 and is threadedly connected with the boss 329. The pressing block 730 is partially arranged in the channel section of the liquid outlet channel 321 located at the boss 329 to achieve a stable connection of the nozzle 710 at the boss 329, and the remaining part can be arranged between the outer side of the boss 329 and the inner side of the nut 720 to achieve a tight connection between the boss 329 and the nut.

[0062] At this time, the valve core component 210 can act on the nozzle 710. For example, when the valve core component 210 moves upward away from the nozzle 710 and continues to move up and down away from the connecting port 322b, the liquid inlet channel 322 and the liquid outlet channel 321 are connected through the connecting port 322b, and the liquid in the liquid storage container 100 can flow to the liquid outlet channel 321 through the liquid inlet channel 322 in turn, and at least fill the channel section located at the protruding column 329; then the valve core component 210 is operated to move downward close to the nozzle 710, so that the valve core component 210 is equivalent to a piston, which can pressurize the liquid filled in the channel section at the protruding column 329 and spray it out through the nozzle 710; on the contrary, when the valve core component 210 moves downward close to and covers the nozzle 710 (it can also cover the connecting port 322b), the liquid in the liquid storage container 100 cannot be discharged outward through the nozzle 710.

[0063] The nozzle 710 can set specific conditions for the liquid spraying parameters according to actual needs. The spraying parameters can be but are not limited to spraying flow rate, spraying direction, spraying frequency, etc.

[0064] In view of the above, before operating the quick-release assembly 400 to connect the first block 310 and the second block 320, it is first necessary to operate the two proximal surfaces 301 of the first block 310 and the second block 320 to approach each other (i.e., achieve approximate engagement). During this process, it is necessary to ensure that the valve core member 210 extends into the liquid outlet channel 321 through the insertion opening 321b. Based on this, in one embodiment, a positioning protrusion 315 is convexly provided on one of the two proximal surfaces 301, and a positioning recess 328 is concavely provided on the other. When the two blocks are engaged, the positioning protrusion 315 is connected to the positioning recess 328 in a concave-convex manner. Through the concave-convex connection between the positioning protrusion 315 and the positioning recess 328, the two proximal surfaces 301 of the first block 310 and the second block 320 can be approximately positioned, so as to ensure that the valve core member 210 can be aligned with the insertion opening 321b and prevent the valve core member 210 from being offset from the insertion opening 321b, resulting in breakage of the valve core member 210. The positioning protrusion 315 can be integrally formed with the proximal surface 301, or the positioning protrusion 315 can also be a pin body structure independently provided from the first block 310 and the second block 320.

[0065] The pressing member 410 in the quick-release assembly 400 can be provided as one or two. When provided as one, driven by the screw member 420, the pressing member 410 connects and fixes the first block 310 and the second block 320 by pressing the first block 310 and the second block 320. When provided as two, the two pressing members 410 are respectively arranged on the front and rear sides of the first block 310 and the second block 320. Driven by the screw member 420, the two pressing members 410 form a clamping structure, which can apply a clamping force to the first block 310 and the second block 320 when approaching each other to connect and fix the first block 310 and the second block 320; conversely, when moving away from each other, the clamping force applied to the first block 310 and the second block 320 can be cancelled to detach the first block 310 and the second block 320. Since the main structures and functions of the two pressing members 410 are basically the same, in the following embodiments, the pressing member 410 located on the rear side of the first block 310 and the second block 320 is mainly used as an example for illustration. Correspondingly, the first side surface 302 of the first block 310 is its rear side surface; the first side surface 302 of the second block 320 is its rear side surface.

[0066] Since the screw connector 420 is threadedly connected to at least the first screw hole 324 in the second block 320 and the second screw hole 411 of the pressing member 410, generally, whether driving the pressing member 410 to move close to the first block 310 and the second block 320 (i.e., joining the first block 310 and the second block 320) or driving the pressing member 410 to move away from the first block 310 and the second block 320 (i.e., detaching the first block 310 and the second block 320), the quick-release assembly 400 is basically in a connected state with the second block 320. In this way, when the first block 310 and the second block 320 are detached, the quick-release assembly 400 itself will not be overly disassembled, avoiding the loss of parts of the quick-release assembly 400, or when joining the first block 310 and the second block 320 next time, the operation of sequentially passing the screw connector 420 through the first threaded hole and the second threaded hole needs to be repeated.

[0067] In order to enable the same pressing member 410 to act on the first block 310 and the second block 320 simultaneously. The plate surface of the pressing member 410 at least covers the partial second side surface 303 of the first block 310 and the partial second side surface 303 on the same side of the second block 320. And further, the pressing area of the pressing member 410 on the first side surface 302 of the first block 310 is not less than the pressing area on the first side surface 302 of the second block 320. It can be understood that the connection between the pressing member 410 and the second block 320 can be achieved both by the mutual pressing force generated and by the screwing connection between the screw connector 420 and the first screw hole 324; while the connection between the pressing member 410 and the first block 310 can only be achieved by the mutual pressing force generated. Therefore, by appropriately increasing the pressing area of the pressing member 410 on the first block 310, the interference amount formed between the two can be effectively increased, and then the connection strength of the pressing member 410 to the first block 310 can be enhanced.

[0068] The pressing member 410 can be directly protrudingly provided at the second side surface 303 of the first block 310 and the second block 320. However, in order to reduce interference, the second side surfaces 303 on the same side of the first block 310 and the second block 320 can be jointly provided with a fitting groove 304 at a position close to their docking position.

[0069] Please combine Figures 7 to 10, the dimensions of the fitting groove 304 in the left - right direction and up - down direction can be approximately adapted to the dimensions of the pressing part 410 to achieve circumferential limitation of the pressing part 410. The dimension of the fitting groove 304 in the front - back direction is generally set to be larger than the corresponding dimension of the pressing part 410, or after being assembled with other components (such as the heat - conducting seat 620 described below), an avoidance groove is provided at the corresponding position of the fitting groove 304 of this component, and the total dimension of the fitting groove 304 and the avoidance groove in the front - back direction is set to be larger than the corresponding dimension of the pressing part 410. In this way, enough moving space can be reserved for the pressing part 410 in the front - back direction.

[0070] The fitting groove 304 has a first side groove wall 311 and a second side groove wall 323 which are oppositely arranged in the up - down direction, and the second side groove wall 323 is formed at the second block 320 and can be in movable or fixed abutment with the pressing part 410 to support the pressing part 410 upward. The first side groove wall 311 is formed at the first block 310. The groove section of the fitting groove 304 located at the first block 310 protrudes with a first rib 312 along the front - back direction at a position spaced from the first side groove wall 311. The surface of the first rib 312 facing the first side groove wall 311 constitutes a first guiding surface 313. A first slot 314 is jointly defined between the first rib 312 and the first side groove wall 311; on one side of the pressing part 410 facing the first side surface 302, second slots 413 are respectively formed corresponding to the first ribs 312, and second ribs 412 are formed corresponding to the first slots 314. The surface of the second rib 412 facing the second slot 413 constitutes a second guiding surface 414. During the screwing process of the screw member 420, the first rib 312 and the first slot 314 are in inserted fit, and the second rib 412 and the second slot 413 are in inserted fit. In this way, it is equivalent to forming a double - inserted fit between the pressing part 410 and the first block 310.

[0071] In Figures 5 to 7 In the structure shown, both the first guiding surface 313 and the second guiding surface 414 are gradually inclined forward from bottom to top. In this way, when the screw member 420 exerts a forward pressure on the pressing part 410, the pressing part 410 is driven to move forward, and its forward movement can exert an increasing extrusion force on the first block 310 and the second block 320, increasing the mutual interference between the first block 310, the second block 320 and the pressing part 410. And when there are two pressing parts 410, at least strict limitation can be formed on the first block 310 and the second block 320 in the front - back direction, and a certain degree of limitation can be formed on the first block 310 and the second block 320 in the up - down direction and the left - right direction. Under the guidance of the first guiding surface 313 and the second guiding surface 414, the forward movement of the pressing part 410 gradually moves upward, and the second block 320 can be driven to gradually move upward by the screw member 420, that is, gradually approach the first block 310, making the connection between the first block 310 and the second block 320 in the up - down direction closer.

[0072] Further, when the second block 320 includes a main block 320a detachably connected to the first block 310 and a side block 320b connected to the left or right side of the main block 320a as described above, the connecting surface between the main block 320a and the side block 320b is an inclined surface 320c, and the inclined surface 320c gradually extends obliquely toward the first block 310 in the direction from the side block 320b to the main block 320a. On the one hand, the inclined surface 320c can flexibly adjust the installation positions between the main block 320a and the side block 320b; on the other hand, the inclined surface 320c can appropriately transfer the upward movement of the main block 320a to the side block 320b through a larger contact surface, driving the side block 320b to move upward more stably, and then making the connection between the side block 320b and the liquid storage container 100 closer.

[0073] The two inclined surfaces 320c can be connected in any way, such as by concave-convex positioning and connection through a concave-convex structure; or by increasing the roughness between the two inclined surfaces 320c. Among them, when the connection is achieved through a concave-convex structure, the concave-convex structure can specifically include a plurality of convex ribs arranged at intervals in the up-down direction, and each convex rib extends in the front-back direction, and a card slot is formed between adjacent two convex ribs. By adjusting the engagement and fixation of the same convex rib with different card slots, the relative positions of the side block 320b and the main block 320a in the up-down direction can also be adjusted, that is, the same second block 320 can be adapted to be installed with the first block 310 and / or the liquid storage container 100 of different specifications.

[0074] The first guiding surface 313 and / or the second guiding surface 414 extending obliquely as described above can be directly set as an inclined plane, or set as a convex arc surface. It can be understood that when set as a convex arc surface, it helps to reduce the sliding friction during the sliding process of the first guiding surface 313 and the second guiding surface 414, so that the sliding of the two is smoother.

[0075] Further, a card slot can be provided at a position of the first guiding surface 313 close to the bottom wall of the first slot 314, and a card projection is provided corresponding to the second guiding surface 414, so that when the first guiding surface 313 and the second guiding surface 414 slide in place, the card slot and the card projection are elastically engaged, which helps to further increase the installation strength. And / or a card slot is provided at a position of the second guiding surface 414 close to the bottom wall of the second slot 413, and a card projection is provided corresponding to the first guiding surface 313, so that when the first guiding surface 313 and the second guiding surface 414 slide in place, the card slot and the card projection are elastically engaged, which helps to further increase the connection strength.

[0076] In addition, on the side surface of the pressing member 410 facing the first block 310, it can be made of an elastic material or provided with an elastic material layer, and at least one concave structure is formed. In this way, when the pressing member 410 gradually approaches and adheres to the second side surface 303 of the first block 310 (including the bottom wall of the first slot 314 and / or the free end surface of the first rib 312), the concave structure is stressed and deformed, which is equivalent to forming a suction cup structure, and a certain adsorption force can be formed between the pressing member 410 and the first side surface 302 of the first block 310, increasing the connection strength between the pressing member 410 and the first block 310.

[0077] Please combine Figure 7 、 Figure 11 and Figure 12 ., a limiting recess 415 is locally formed on the side of the pressing member 410 facing away from the second block 320; the second block 320 further has a second side surface 303 connected to the left side and / or the right side of the proximal surface 301, and an installation groove 325 is formed on the second side surface 303, and a jack 326 communicating with the fitting groove 304 is formed in the installation groove 325; the quick-release valve further includes a limiting member 500, the limiting member 500 includes a limiting body 510 and a limiting protrusion 520 protruding from the limiting body 510 in the left-right direction, the limiting body 510 is installed in the installation groove 325, the limiting protrusion 520 passes through the jack 326 and extends into the fitting groove 304, and when the pressing member 410 moves away from the block, the limiting protrusion 520 abuts against the limiting recess 415 to limit the pressing member 410 from disengaging from the groove section of the fitting groove 304 located at the second block 320.

[0078] The orientation of the installation groove 325 is related to the position of the pressing member 410, that is, the installation groove 325 is arranged close to the pressing member 410 on the left side and / or the right side of the second block 320, specifically, for example, on the right side in the figure. The installation groove 325 and the jack 326 can be defined by the second block 320 alone. Of course, they can also be jointly defined by the second block 320 and other components (such as the heat conduction seat 620 described below). The limiting body 510 of the limiting protrusion 520 can be fixedly inserted into the installation groove 325 by means of, for example, interference fit. Or the limiting protrusion 520 can be fixedly inserted into the installation groove 325 by means of, for example, screw fixation, snap fixation, magnetic attraction fixation, etc. When there is one pressing member 410, one limiting protrusion 520 is correspondingly provided. At this time, the limiting body 510 and the limiting protrusion 520 are generally in an L shape. When there are two pressing members 410, two limiting protrusions 520 are correspondingly provided. At this time, the limiting body 510 and the limiting protrusion 520 are generally in a U shape.

[0079] It can be understood that when the pressing member 410 approaches and presses the first block 310 and the second block 320, the pressing member 410 is at the forward limit position. At this time, there is a sufficient distance between the limiting convex portion and the limiting concave portion 415, and there is no need for the limiting member 500 to play a role in limiting the pressing member 410 backward. During the process of the pressing member 410 moving away from the first block 310 and the second block 320, it will first move backward until it completely releases the pressing force on the first block 310 (defined as the first position); it can also continue to move backward a certain distance after the first position to the second position. Then, according to actual needs, it can be set that when at the first position or the second position, the limiting convex portion and the limiting concave portion 415 stop and abut, and the limiting member 500 plays a role in limiting the pressing member 410 backward.

[0080] In the above, at least one assembly hole 327 is further formed on the periphery of the first screw hole 324 of the second block 320. The quick-release valve further includes at least one elastic member 430. The elastic member 430 is inserted through the assembly hole 327 and is compressed and deformed when the screw member 420 drives the pressing member 410 to move close to the second block 320. Of course, according to actual needs, an assembly hole 327 can also be formed at the corresponding position of the pressing member 410. The assembly hole 327 here can be a through hole (the size can be smaller than the size of the elastic member 430) or a blind hole. The assembly hole 327 can realize the stable installation of the elastic member 430. When the screw member 420 is screwed outwards to cancel the pressing force on the pressing member 410, the elastic member 430 can drive the pressing member 410 to move back and bounce through its restored deformation, which helps to quickly release the clamping of the first block 310.

[0081] And / or, the quick-release valve further includes a snap ring 440. The snap ring 440 is sleeved on the outer periphery of the screw member 420 and is limited between the pressing member 410 and the second block 320. On the one hand, the snap ring 440 can have the ability of elastic deformation in the front-back direction, so that there is elastic abutment between the screw member 420 and the second block 320 in the front-back direction, and it helps the sealing connection between the screw member 420 and the first screw hole 324 and the second screw hole 411. On the other hand, the snap ring 440 can also have a certain ability of elastic deformation in the up-down direction, so that when the first block 310 and the second block 320 are driven to approach each other under the guiding action of the first guiding surface 313 and the second guiding surface 414, elastic abutment between the screw member 420 and the second block 320 can be realized in the up-down direction.

[0082] And / or, the screwing member 420 includes an operating section 422 exposed outside the first screwing hole 324 and the second screwing hole 411, and the operating section 422 is arranged in a butterfly shape. A step may be formed between the operating section 422 and the screwing section 421, so that the operating section 422 does not completely extend into the first screwing hole 324 and the second screwing hole 411, and the pressing member 410 can be applied with a forward pressure through the step. The butterfly shape of the operating section 422 helps to form a larger size and a more suitable shape for the operator to manually rotate, and can also prevent slipping during rotation.

[0083] Based on one or several of the above embodiments, the quick-release valve further includes a heating module, and the heating module includes a heating device 610 and a heat conducting seat 620 connected to each other. The heating device 610 is used to generate heat, and may include, for example, a heating rod, a heating resistance wire, an electromagnetic heating structure, etc. The heat conducting seat 620 at least partially wraps the outside of the block connected to the liquid storage container 100 to transfer heat to the liquid in the liquid inlet channel 322 and / or the liquid outlet channel 321. The heat conducting seat 620 can be made of any suitable heat conducting material and formed into any suitable shape. On the one hand, the heat conducting seat 620 can assist in connecting the heating device 610, the second block 320, the limiting member 500, the quick-release assembly 400, etc. into one body; on the other hand, the heat conducting seat 620 can heat the second block 320, for example, which it wraps. Correspondingly, the second block 320 can also be made of a heat conducting material, and can continue to transfer the heat transferred by the heat conducting seat 620 to the liquid inlet channel 322 and / or the liquid outlet channel 321, so that the liquid reaches the required temperature.

[0084] Further, the quick-release valve further includes at least one ball 630. The ball 630 is rotatably installed on the proximal surface 301 of a block and abuts against the proximal surface 301 of another block, so that the distance between the two proximal surfaces 301 is the same. Taking the ball 630 rotatably installed on the proximal surface 301 of the first block 310 and abutting against the proximal surface 301 of the second block 320 as an example. The proximal surface 301 of the first block 310 may be provided with an arc-shaped groove, and the ball 630 is rotatably installed in the arc-shaped groove in all directions or in multiple directions. The part of the ball 630 facing the proximal surface 301 of the second block 320 may maintain a spherical shape, or may be locally flattened to form a relatively small abutting plane. On the one hand, the setting of the ball 630 can reduce the flatness requirements for the proximal surface 301 of the first block 310 and the proximal surface 301 of the second block 320; on the other hand, the setting of the ball 630 can reduce the abutting area between the proximal surface 301 of the first block 310 and the proximal surface 301 of the second block 320, thereby reducing the heat exchange efficiency between the first block 310 and the second block 320 to a certain extent, and avoiding too much heat of the second block 320 being transferred to the first block 310 and further transferred to the valve body assembly 200.

[0085] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
