Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, and more particularly to a two-way plug-in connector. Background Art

[0002] Beverage making equipment such as milk cap machines generally have a material storage area. In order to facilitate access, it is often designed as a detachable independent raw material box. There are usually two ways to extract raw materials: one is to directly set an opening at the top of the raw material box, and the extraction tube directly extends into the raw material box through this opening to extract the raw materials; the other is to set a docking socket at the bottom of the raw material box, and connect the male end of the docking plug to the discharge tube to realize the extraction of raw materials. However, when the raw materials are insufficient, the first method will cause the raw materials to be exhausted, and some raw materials will remain at the bottom of the raw material box and cannot be extracted, resulting in a waste of raw materials; in addition, when the raw material box is pulled out of the machine body, due to the certain viscosity of the raw materials themselves, they will stick to the bottom of the extraction tube, and the raw material box will cause dripping after being pulled out, affecting the user experience. Although the second method avoids the problem of residual raw materials, most of the existing two-way connectors on the market need to be manually unlocked, which is not convenient for insertion and separation. In addition, the spring is usually in direct contact with the liquid, which is easy to accumulate liquid and difficult to clean.

[0003] For example, Patent No. CN118302627A discloses a fluid coupling comprising a male connector and a female connector, each of which includes an internal fluid conduit and a valve resiliently displaceable within the conduit. The valves interact with each other by pushing each other into a fluid-open position, and when the two connectors are disengaged, the valves resiliently return to a position where the conduit is sealed by a closure head. Although this prior art achieves sealing through the valve in the conduit, the spring and valve are placed directly within the conduit, bringing them into direct contact with the fluid within the conduit, thus affecting the hygiene of the raw materials. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a two-way plug-in connector, which can be easily plugged in and disassembled, and effectively ensures sealing and interception to prevent leakage.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a two-way plug-in connector, including a male end connector and a female end connector; the male end connector includes a male base, a first spring, a first push rod, a first leather cup and a male connector part, the male connector part includes a discharge connector and a male connector, and a convex point is provided on the side of the discharge connector facing the female end connector; the male connector part is fixed on the male base, the rear end of the first push rod is arranged in the male base and a first spring is provided between the male base, the front end of the first push rod is located in the male connector part and is sleeved with a first leather cup, the first leather cup is used to block or open the communication port between the discharge connector and the male connector; the female end connector includes a female connector part, a second leather cup, an upper shell of the female base, a slider, a slider spring, a second push rod, a second spring and a lower shell of the female base, and the female connector part , the upper shell of the mother base and the lower shell of the mother base are fixedly connected in sequence; the mother joint part includes a feed port and a mother joint, and the mother joint is provided with a pin extending to the outside of its outlet; the slider is provided in a slide groove on the upper shell of the mother base, and a slider spring is provided between the front end of the slider and the inner wall of the slide groove, and the rear end of the slider is located at the opening of the slide groove and corresponds to the position of the protrusion; the lower end of the second push rod is provided in the lower shell of the mother base and a second spring is provided between the lower shell of the mother base, and the upper end of the second push rod passes through the slider and the through hole in the middle of the upper shell of the mother base in sequence to enter the mother joint part, and the upper end of the second push rod is provided with a second leather cup, and the second leather cup is used to seal or open the connecting hole between the feed port and the mother joint; the middle part of the second push rod is provided with a conical surface which is wide at the top and narrow at the bottom, and the inner side of the through hole in the middle of the slider is provided with an inclined platform matching the conical surface.

[0006] The present technical solution provides a bidirectional plug-in connector, comprising a male connector and a female connector, each of which is provided with a spring, a push rod, and a leather cup. The male connector is provided with a protrusion, while the female connector is provided with a push pin and a slider with a ramp. When the male connector is inserted, the push pin of the female connector pushes open the first leather cup inside the male connector, creating a passage for the male connector; at the same time, the protrusion of the male connector presses against the slider, causing it to move relative to the slider in the horizontal direction. Since the ramp on the slider cooperates with the conical surface on the second push rod, the second push rod moves axially upward as the slider moves horizontally, creating a passage for the female connector, thereby achieving internal communication between the two connectors during plug-in connection.

[0007] In a preferred technical solution, the first leather cup includes a front bowl portion and a rear bowl portion with openings facing opposite directions. The diameter of the front bowl portion is smaller than the diameter of the rear bowl portion and larger than the inner diameter of the male joint. The edge of the front bowl portion abuts against the cavity wall around the communication port between the discharge joint and the male joint, and the edge of the rear bowl portion is located in the gap between the male base and the male joint portion, so that the inner cavity of the male joint portion is completely isolated from the first spring and the first push rod.

[0008] The second leather bowl includes an upper bowl portion and a lower bowl portion with openings facing opposite to each other. The diameter of the upper bowl portion is smaller than the diameter of the lower bowl portion. The edge of the upper bowl portion rests on the cavity wall around the feed port and the connecting hole of the female joint, and the edge of the lower bowl portion is located in the gap between the female joint portion and the upper shell of the female base, so that the inner cavity of the female joint portion is completely isolated from the second push rod and the second spring.

[0009] The first leather cup and the second leather cup used in this technology both include two bowl parts with openings facing opposite directions, which can play a double sealing role inside and outside. The bowl part with a small diameter is used to seal and open the flow channel inside the joints at both ends, and the bowl part with a large diameter can isolate the push rod, spring, slider and other components from the flow channel, that is, the push rod, spring, etc. are all placed outside the flow channel and have no contact with the fluid in the flow channel, which is suitable for fields that come into contact with food; at the same time, because the leather bowl structure is smooth and has no cleaning dead corners, it is easy to clean as a whole, can effectively prevent residue, and is more hygienic and environmentally friendly.

[0010] In a preferred embodiment, the male base is provided with a first recess for accommodating the first push rod, the bottom of the first push rod is provided with a first mounting groove, and the first spring is disposed between the bottom surface of the first mounting groove and the bottom surface of the first recess. This technology ensures a secure assembly of the male connector while preventing the movement of the first push rod and the first spring from shifting, thereby enhancing the stability of the bidirectional plug-in connector.

[0011] In a preferred embodiment, the lower shell of the female base is provided with a second recess for accommodating the second push rod. A second mounting groove is provided at the bottom of the second push rod, and a second spring is positioned between the bottom of the second mounting groove and the bottom of the second recess. This technique ensures secure assembly of the female connector while preventing the second push rod and second spring from shifting in direction, thereby enhancing the stability of the bidirectional plug-in connector.

[0012] In a preferred technical solution, first mounting columns are provided at the four corners of the male connector, and first mounting through holes are provided at the four corners of the male base. Each first mounting column passes through each first mounting through hole and is fixed to the male base by screws, making the installation more secure.

[0013] In a preferred technical solution, second mounting columns are provided at the four corners of the female connector, and second mounting through holes are provided on the upper shell and the lower shell of the female base. Each second mounting column passes through each second mounting through hole and is fixedly connected to the upper shell and the lower shell of the female base, so that the connection is more firm and can better ensure the stability of the product.

[0014] In a preferred technical solution, a sealing ring is provided at the front end of the male connector to enhance the sealing performance.

[0015] In a preferred technical solution, a circumferential groove for accommodating a sealing ring is provided on the front outer wall of the male connector, wherein the sealing ring is provided in the circumferential groove to better perform a sealing function.

[0016] In a preferred technical solution, the male connector is fixed inside the beverage making device's chassis, and the discharge connector is used to connect to the beverage making device's draw tube. The female connector is screwed to the bottom of the beverage making device's raw material tank, and the feed port communicates with the tank's internal cavity. In this technology, the male connector is a fixed component, while the female connector is a movable component fixed to the bottom of the raw material tank, allowing for easy disassembly. The flow channel opens when the two connectors are connected, and flow is blocked when they are separated, effectively preventing leakage of raw materials from the raw material tank and draw tube.

[0017] In a preferred technical solution, both the first leather cup and the second leather cup are made of silicone material that meets food safety requirements, thereby ensuring food safety.

[0033] Reference Figure 1-8 A bidirectional plug-in connector according to an embodiment of the present utility model is described.

[0034] In one embodiment, Figure 1-7As shown, a two-way plug-in connector includes a male end connector 1 and a female end connector 2 that can be plugged into each other.

[0035] The male end connector 1 includes a male base 11, a first spring 12, a first push rod 13, a first leather cup 14 and a male connector part 15. The male connector part 15 includes a discharge connector 151 and a male connector 152. The discharge connector 151 is provided with a protrusion 16 on the side facing the female end connector 2. The male connector part 15 is fixed on the male base 11. The rear end of the first push rod 13 is arranged in the male base 11 and a first spring 12 is provided between the male base 11. The front end of the first push rod 13 is located in the male connector part 15 and is sleeved with the first leather cup 14. The first leather cup 14 is used to seal or open the communication port between the discharge connector 151 and the male connector 152.

[0036] The female end connector 2 includes a female connector portion 21, a second leather cup 22, a female base upper shell 23, a slider 24, a slider spring 25, a second push rod 26, a second spring 27 and a female base lower shell 28. The female connector portion 21, the female base upper shell 23 and the female base lower shell 28 are fixedly connected in sequence; the female connector portion 21 includes a feed port 211 and a female connector 212, and the female connector 212 is provided with a push pin 213 extending to the outside of its outlet.

[0037] The slider 24 is arranged in the slide groove on the upper shell 23 of the mother base, and a slider spring 25 is provided between the front end of the slider 24 and the inner wall of the slide groove. The rear end of the slider 24 is located at the opening of the slide groove and corresponds to the position of the protrusion 16; the lower end of the second push rod 26 is arranged in the lower shell 28 of the mother base and a second spring 27 is provided between the lower shell 28 of the mother base. The upper end of the second push rod 26 passes through the through holes in the middle of the slider 24 and the upper shell 23 of the mother base in turn and enters the female joint part 21. The upper end of the second push rod 26 is provided with a second leather cup 22, and the second leather cup 22 is used to seal or open the connecting hole between the feed port 211 and the female joint 212.

[0038] A tapered surface 261 that is wider at the top and narrower at the bottom is provided in the middle of the second push rod 26 , and an inclined platform 241 that cooperates with the tapered surface 261 is provided inside the through hole in the middle of the slider 24 .

[0039] Among them, in the male end connector 1, there is a movable gap between the first push rod 13 and the male base 11, and the first spring 12 is assembled in the movable gap, and pushes the first push rod 13 by compressing the elastic force so that the first leather cup 14 blocks the connecting port between the discharge connector 151 and the male connector 152. The discharge connector 151 is set vertically upward, and the male connector 152 is set toward the front end.

[0040] In the female connector 2, clearances for springs are provided between the slider 24 and the upper housing 23 of the female base, and between the second push rod 26 and the lower housing 28 of the female base. These clearances are fitted with a slider spring 25 and a second spring 27, respectively. The second spring 27 pushes the second push rod 26, causing the second leather cup 22 to block the communication hole between the feed port 211 and the female connector 212. One end of the push pin 213 is located inside the female connector 212, and the other end extends outside the outlet of the female connector 212.

[0041] In practice, when male connector 1 and female connector 2 are plugged together, ejector pin 213 pushes open first leather cup 14 to connect the internal passage of male connector 1. Protrusion 16 pushes against slider 24, and the inclined platform 241 cooperates with tapered surface 261 to move second ejector pin 26 upward, connecting the internal passage of female connector 2 and achieving bidirectional connection. The outer diameter of male connector 152 is equal to or smaller than the inner diameter of female connector 212 to achieve plug-in connection. When the outer diameter of male connector 152 is equal to the inner diameter of female connector 212, a sealing effect is achieved.

[0042] The above embodiment provides a two-way plug-in connector, which can be easily disassembled without the aid of other tools, and can also realize simultaneous opening and closing of the connectors at both ends, thereby stopping the flow in a timely and effective manner and preventing the leakage of raw materials in the raw material box and the extraction pipe.

[0043] In this embodiment, the first leather cup 14 includes a front bowl portion and a rear bowl portion with openings facing opposite directions. The diameter of the front bowl portion is smaller than the diameter of the rear bowl portion and larger than the inner diameter of the male joint 152; the edge of the front bowl portion rests on the cavity wall around the connecting port between the discharge joint 151 and the male joint 152, and the edge of the rear bowl portion is located in the gap between the male base 11 and the male joint portion 15, so that the inner cavity of the male joint portion 15 is completely isolated from the first spring 12 and the first push rod 13.

[0044] The second leather cup 22 includes an upper bowl portion and a lower bowl portion with openings facing opposite to each other. The diameter of the upper bowl portion is smaller than the diameter of the lower bowl portion. The edge of the upper bowl portion rests on the cavity wall around the connecting hole between the feed port 211 and the female connector 212. The edge of the lower bowl portion is located in the gap between the female connector portion 21 and the upper shell 23 of the female base, so that the inner cavity of the female connector portion 21 is completely isolated from the second push rod 26 and the second spring 27.

[0045] Among them, the first leather cup 14 and the second leather cup 22 can play a double sealing role inside and outside. The front bowl and upper bowl with small diameter are used to block and open the flow channel inside the joints at both ends, and the rear bowl and lower bowl with large diameter can isolate the push rod, spring, slider and other components from the flow channel, that is, the push rod, spring, etc. are all placed outside the flow channel and have no contact with the fluid in the flow channel, which is suitable for fields that come into contact with food; at the same time, because the leather bowl structure is smooth and has no cleaning dead corners, it is easy to clean as a whole, which can effectively prevent raw material residue and is more hygienic and environmentally friendly.

[0046] In this embodiment, the male base 11 is provided with a first groove for accommodating the first push rod 13 , the bottom of the first push rod 13 is provided with a first installation groove, and the first spring 12 is provided between the bottom surface of the first installation groove and the bottom surface of the first groove.

[0047] Furthermore, the lower shell 28 of the mother base is provided with a second groove for accommodating the second push rod 26, the bottom of the second push rod 26 is provided with a second mounting groove, and the second spring 27 is provided between the bottom surface of the second mounting groove and the bottom surface of the second groove.

[0048] In the above embodiment, the push rod is installed in the groove of the base, and the spring is installed in the installation groove at the bottom of the push rod. While ensuring the stable assembly, it can also effectively prevent the movement direction of the push rod and the spring from deviating, thereby enhancing the stability of the two-way plug-in connector.

[0049] In this embodiment, first mounting posts are provided at the four corners of the male connector 15, and first mounting through holes are provided at the four corners of the male base 11. Each first mounting post passes through each first mounting through hole and is fixed to the male base 11 by screws.

[0050] Furthermore, second mounting columns are provided at the four corners of the female connector part 21, and second mounting through holes are provided on the female base upper shell 23 and the female base lower shell 28. Each second mounting column passes through each second mounting through hole and is fixedly connected to the female base upper shell 23 and the female base lower shell 28.

[0051] In the above embodiment, both the male and female connectors are fixedly connected to their corresponding bases via mounting posts, which makes the connection more secure and can better ensure product stability.

[0052] In this embodiment, a sealing ring 17 is sleeved on the front end of the male connector 152 for sealing.

[0053] Furthermore, a circumferential groove for accommodating the sealing ring 17 is provided on the front end outer wall of the male connector 152. The sealing ring 17 is an annular sealing ring, which is arranged in the circumferential groove and can better play a sealing role.

[0054] In this embodiment, if Figure 8 As shown, the male end connector 1 is fixed inside the chassis 301 of the beverage making device, and the discharge connector 151 is used to connect to the extraction pipe of the beverage making device; the female end connector 2 is fixed to the bottom of the raw material box 302 of the beverage making device by screws, and the feed port 211 is connected to the inner cavity of the raw material box 302.

[0055] The beverage making device may be, but is not limited to, a milk cap machine, a cold drink machine, or the like with its own raw material box 302 , wherein the male connector 1 is a fixed part, and the female connector 2 is a movable part fixed to the bottom of the raw material box.

[0056] When the raw material box is loaded into the chassis of the beverage making device, the female end connector 2 is docked with the male end connector 1. The docking process of the male end connector 1 and the female end connector 2 is as follows:

[0057] First, the male connector 152 of the male end connector 1 extends into the female connector 212, and the sealing ring 16 will seal the channel connecting the two end connectors. The ejector pin 213 at the outlet of the female end connector 2 will push open the first leather cup 14 and the first ejector rod 13 inside the male end connector 1, compressing the first spring 12, so that the fluid channel inside the male end connector 1 is opened; at the same time, the protrusion 16 of the male end connector 1 pushes against the slider 24 of the female end connector 2. Since the inclined platform 241 on the slider 24 cooperates with the conical surface 261 of the second ejector rod 26, when the slider 24 moves horizontally, the second ejector rod 26 will make an axial movement, thereby lifting the second leather cup 22, so that the fluid channel inside the female end connector 2 is opened. Figure 8 The middle arrow points to the direction of raw material flow. At this time, the first spring 12 in the male connector 1 and the slider spring 25, the second spring 27 and other internal springs in the female connector 2 are all in a compressed state.

[0058] Similarly, the raw material box is pulled out, and the female end connector 2 is separated from the male end connector 1. During the separation process of the two end connectors, the force applied to each spring gradually disappears. Finally, all the springs return to the uncompressed state, and the first push rod 13 and the second push rod 26 respectively bring the first leather cup 14 and the second leather cup 22 back to the initial position, so that the channels inside the two end connectors are blocked and closed, thereby realizing flow interception at both ends.

[0059] In this embodiment, the first leather cup 14 and the second leather cup 22 are both made of silicone that meets food safety requirements.

[0060] During specific implementation, the leather cup structure is in the flow channel and in contact with the raw materials. The use of silicone material that meets food safety requirements can ensure food safety.
