本发明的一种咖啡机奶路清洗装置可以实现加热牛奶和清洗牛奶回路的自动化切换，实现此功能的原理如下：奶路清洗装置初始位置在图2-1所示的奶路清洗装置制作牛奶回路，此时与奶路清洗装置相连的牛奶容器中的牛奶管在凸轮滑块推动下是打开的状态，现在要切换到图2-3所示的奶路清洗装置清洗牛奶回路，首先步进电机通电后拉着铜螺帽与阀芯内套筒组成的组件向左滑动第一段行程距离，因阀芯内套筒、阀芯外套筒和凸轮连杆可以同步滑动，凸轮连杆也随之向左滑动相应行程距离，凸轮连杆与凸轮滑块组成的凸轮运动会迫使凸轮滑块向右保护罩外侧方向滑动，凸轮滑块又会推动与奶路清洗装置相连的牛奶容器内的插头组件滑动护罩204运动，夹紧牛奶容器中的牛奶管202，此时切换阀阀芯头部的塔形密封圈仍然将清洗水路入口132封死，即阀芯组件是没有动的，这便是切换清洗回路的第一步，夹紧牛奶管202，维持阀芯组件位置不 动，此时奶路清洗装置回路位置在图2-2所示的奶路清洗装置过度回路状态，第二步：步进电机通电继续通电拉动铜螺帽与阀芯内套筒组成的阀芯组件继续向左滑动第二段行程距离，此过程中阀芯外套筒会拉动阀芯组件一起向左滑动第二段行程距离，此时切换阀阀芯头部的塔形密封圈避开清洗水路入口，清洗水路入口处于打开状态，牛奶容器中的牛奶管继续保持夹紧状态。至此便完成从制作牛奶回路到清洗牛奶回路的切换动作，此时奶路清洗装置回路位置在图2-3奶路清洗装置清洗牛奶回路状态，当要从清洗牛奶回路切换到制作牛奶回路时，只需将上述会路切换步骤倒着执行即可，即先关闭清洗水路入口，再打开牛奶管，在切换过程中利用第一段行程距离、第二段行程距离的差值与总的形成距离之间的差值，实现清洁水路入口的关闭开启与牛奶管的夹紧与开启的先后切换，从而实现一种自动化切换回路的奶路清洗装置，回路切换主要得益于步进电机与切换阀组件组成的传动组件。The milk circuit cleaning device of the coffee machine of the present invention can realize the automatic switching of heating milk and cleaning the milk circuit. The principle of this function is as follows: the initial position of the milk circuit cleaning device is the milk circuit cleaning device shown in Figure 2-1 to make milk At this time, the milk tube in the milk container connected to the milk path cleaning device is opened under the push of the cam slider. Now it is necessary to switch to the milk path cleaning device cleaning milk circuit shown in Figure 2-3. First step After the motor is energized, the assembly composed of the copper nut and the inner sleeve of the valve core slides to the left for the first stroke distance. Because the inner sleeve of the valve core, the outer sleeve of the valve core and the cam connecting rod can slide synchronously, the cam connecting rod also With the corresponding stroke distance sliding to the left, the cam movement composed of the cam connecting rod and the cam slider will force the cam slider to slide to the outside of the right protective cover, and the cam slider will push the plug in the milk container connected to the milk path cleaning device The component sliding shield 204 moves to clamp the milk tube 202 in the milk container. At this time, the tower sealing ring on the head of the switching valve spool still seals the cleaning water inlet 132, that is, the spool assembly does not move. It is the first step to switch the cleaning circuit. Clamp the milk pipe 202 and maintain the position of the valve core assembly. At this time, the circuit position of the milk circuit cleaning device is in the excessive circuit state of the milk circuit cleaning device as shown in Figure 2-2. The second step : The stepper motor is energized and continues to be energized to pull the spool assembly composed of the copper nut and the inner sleeve of the spool to continue sliding to the left for the second stroke distance. During this process, the outer sleeve of the spool will pull the spool assembly to the left and slide the first Two stroke distances. At this time, the tower sealing ring on the head of the switching valve core avoids the cleaning water inlet, the cleaning water inlet is in an open state, and the milk tube in the milk container continues to be clamped. At this point, the switching action from making milk circuit to cleaning milk circuit is completed. At this time, the position of the milk circuit cleaning device circuit is shown in Figure 2-3. Milk circuit cleaning device cleaning milk circuit status. When switching from cleaning milk circuit to making milk circuit You only need to perform the above-mentioned meeting route switching step backwards, that is, first close the cleaning water entrance, and then open the milk pipe. During the switching process, the difference between the first and second stroke distances and the total forming distance are used. The difference between the clean water inlet and the clamping and opening of the milk pipe are switched sequentially, thereby realizing a milk cleaning device with an automatic switching circuit. The switching of the circuit is mainly due to the stepping motor and the switching valve. Transmission components composed of components.
如图2-4、图2-5所示，其中，切换阀阀体13中有四个出入口，包括：阀芯组件运动型腔131、清洗水路入口132、清洗奶管连接口133及加热水蒸气入口134，所述清洗奶管的一端接口与所述清洗奶管连接口相连接，另一端与牛奶容器插头相连，在牛奶清洗回路中，如图3所示，本发明采用的清洗奶管采用独特的结构设计，其一端接口与切换阀阀体的清洗奶管连接口133出口相连，一端与牛奶容器插头201相连，输出端连接于咖啡机的奶沫器出口端，在咖啡机清洁水沿着清洗水路入口进入经过清洗奶管连接口流向清洗奶管回路时，清洁水会持续不断的经过牛奶容器插头，达到清洁牛奶瓶出口的功能，清洁水又会继续顺着清洗奶管管路清洁奶沫器等其他牛奶***回路，做到了零残留清洁牛奶***回路，保证了牛奶***回路中零残留牛奶，不易滋生细菌，本发明解决了市场上全自动咖啡机无法做到彻底清洗牛奶***回路的难题，确保了咖啡机 在制作牛奶饮品过程中的食品安全。As shown in Figure 2-4 and Figure 2-5, the switch valve body 13 has four inlets and outlets, including: the valve core assembly movement cavity 131, the cleaning water inlet 132, the cleaning milk pipe connection port 133, and heating water Steam inlet 134, one end of the cleaning milk tube is connected to the cleaning milk tube connection port, and the other end is connected to the milk container plug. In the milk cleaning circuit, as shown in FIG. 3, the cleaning milk tube used in the present invention Adopting a unique structural design, one end of the interface is connected to the outlet of the cleaning milk pipe connection port 133 of the switching valve body, one end is connected to the milk container plug 201, and the output end is connected to the milk frother outlet of the coffee machine. The clean water in the coffee machine When it enters along the inlet of the cleaning water path and flows through the connection port of the cleaning milk pipe to the cleaning milk pipe loop, the clean water will continue to pass through the milk container plug to achieve the function of cleaning the milk bottle outlet, and the clean water will continue to clean the milk pipe pipeline. Clean the milk frother and other milk system circuits to achieve zero-residue clean milk system circuits, ensure zero residual milk in the milk system circuits and prevent bacteria from growing. The invention solves the problem that the fully automatic coffee machines on the market cannot completely clean the milk system The difficulty of the circuit ensures the food safety of the coffee machine in the process of making milk beverages.
进一步地，如图5-6、5-7和5-8所示，牛奶容器20包括牛奶容器插头201、牛奶管202、奶管导向固定罩203、插头组件滑动护罩204、插头组件固定座205以及复位弹簧206，牛奶管的一端从奶管导向固定罩内穿过插设于牛奶容器插头上，并通过奶管导向固定罩夹紧固定于牛奶容器插头内，牛奶容器插头201和牛奶管202套设于插头组件滑动护罩内组成插头组件，插头组件滑动护罩在凸轮滑块的推动下实现轴向滑动，此时插头组件滑动护罩内的筋位会向内侧压牛奶容器插头的弹片2011，牛奶容器插头的弹片2011便向内侧挤压牛奶管，使得牛奶管封闭，复位弹簧的一端与插头组件固定座相抵，另一端与插头组件滑动护罩相抵，复位弹簧可驱使插头组件滑动护罩回弹复位。Further, as shown in Figures 5-6, 5-7 and 5-8, the milk container 20 includes a milk container plug 201, a milk tube 202, a milk tube guide and fixed cover 203, a plug assembly sliding shield 204, and a plug assembly fixing seat 205 and a return spring 206, one end of the milk tube passes through the milk tube guide and fixed cover and is inserted into the milk container plug, and is clamped and fixed in the milk container plug by the milk tube guide and fixed cover, the milk container plug 201 and the milk tube 202 is sleeved in the plug assembly sliding shield to form a plug assembly. The plug assembly sliding shield realizes axial sliding under the push of the cam slider. At this time, the ribs in the plug assembly sliding shield will press the milk container plug toward the inside. Shrapnel 2011, the shrapnel 2011 of the milk container plug squeezes the milk tube inwardly, so that the milk tube is closed. One end of the return spring abuts against the plug assembly fixing seat, and the other end abuts against the plug assembly sliding shield. The return spring can drive the plug assembly to slide. The guard rebounds to reset.
如图4-1和4-2所示，当牛奶容器插头201***本发明的奶路清洗装置中时，牛奶容器插头周向环形凸起2012推动凸轮滑块左、右两侧的弹性卡扣7向各自弹簧(B)的压缩方向运动，迫使两侧的弹簧(B)压缩，当牛奶容器插头准确***奶路清洗装置后，两侧的弹簧(B)会给两侧的弹簧卡扣一个回弹力，迫使他们复位，此时两侧的弹簧卡扣卡在牛奶容器插头的环形凹槽中，起到了卡扣连接的功能。如图4-1所示，牛奶容器与奶路清洗装置连接示意图，而此时，牛奶容器插头与凸轮滑块在周向仍可以旋转，牛奶容器插头上的定位PIN 2013可***凸轮滑块固定座凹槽中并与之相配合，从而限制了牛奶容器插头周向旋转自由度，需要说明的是，安装完成后，凸轮滑块固定座上凹槽的位置与凸轮滑块上竖直凹槽51的位置相重合，在定位PIN 2013***凸轮滑块固定座上的凹槽时，定位PIN会将嵌入在凸轮滑块固定座与凸轮滑块重合组成的四周封闭的竖直凹槽51中的按键推动向上运动，按键向上运动时会推动按键检测装置内的检测按钮通电并反馈给咖啡机控制***，此时咖啡机控制***便判断牛奶容器已经安装正确，可以进行牛奶饮品制作以及牛奶回路清洗动作，否则咖啡机控制***会提示未检测到牛奶容器，无法执行牛奶饮品制作和牛奶回路清洗动作。As shown in Figures 4-1 and 4-2, when the milk container plug 201 is inserted into the milk circuit cleaning device of the present invention, the circumferential annular protrusion 2012 of the milk container plug pushes the elastic buckles on the left and right sides of the cam slider 7 Move to the compression direction of the respective springs (B) to force the springs (B) on both sides to compress. When the milk container plug is correctly inserted into the milk path cleaning device, the springs (B) on both sides will buckle the springs on both sides. The resilience forces them to reset. At this time, the spring buckles on both sides are stuck in the annular groove of the milk container plug, which functions as a buckle connection. As shown in Figure 4-1, the schematic diagram of the connection between the milk container and the milk circuit cleaning device, and at this time, the milk container plug and the cam slider can still rotate in the circumferential direction, and the positioning PIN 2013 on the milk container plug can be inserted into the cam slider to fix In the seat groove and matched with it, thereby limiting the degree of freedom of the milk container plug’s circumferential rotation, it should be noted that after the installation is completed, the position of the groove on the cam slider fixing seat is the same as the vertical groove on the cam slider The position of 51 coincides. When the positioning PIN 2013 is inserted into the groove on the cam slider fixing seat, the positioning PIN will be embedded in the closed vertical groove 51 formed by the overlapping of the cam slider fixing seat and the cam slider. Push the button to move upwards. When the button moves up, the detection button in the button detection device will be energized and fed back to the coffee machine control system. At this time, the coffee machine control system will determine that the milk container has been installed correctly, and milk beverage production and milk circuit cleaning can be carried out. Otherwise, the coffee machine control system will prompt that the milk container is not detected, and the milk beverage preparation and milk circuit cleaning actions cannot be performed.
牛奶容器***到奶路清洗装置后，咖啡机便可制作牛奶饮品和奶路清洗动作， 在制作牛奶饮品时牛奶会在奶沫器的负高压作用下从牛奶容器的奶管流到清洗奶管中然后进行加热等动作，而在执行奶路清洗动作时，必须要将牛奶容器的奶管封死才能进行清洗动作，以防止在清洗过程中清洗牛奶回路的废水流到牛奶容器中，污染了牛奶容器中的牛奶。为达到这样的功能，凸轮连杆和环形的凸轮滑块一起组成了可以周期性滑动的装置。After the milk container is inserted into the milk line cleaning device, the coffee machine can make milk drinks and milk line cleaning actions. When making milk drinks, the milk will flow from the milk tube of the milk container to the clean milk tube under the negative high pressure of the milk frother. In order to prevent the waste water from cleaning the milk circuit from flowing into the milk container during the cleaning process, the milk tube of the milk container must be sealed to prevent the waste water from cleaning the milk circuit from flowing into the milk container during the cleaning process. Milk in a milk container. In order to achieve this function, the cam link and the annular cam slider together form a device that can slide periodically.
具体实施方案如下：步进电机推动切换阀组件运动，切换阀组件带动凸轮连杆一起滑动；在凸轮连杆上有由两个连杆限位凸台构成的限位滑动凹槽，在环形的凸轮滑块上有与水平线成一定夹角的滑块限位凸台，如图5-1和图5-2所示，凸轮连杆在轴向做往复滑动时限位滑动凹槽会包裹滑块限位凸台，并使凸轮滑块做上下轴向往复运动，从而实现了步进电机推动、切换阀阀芯组件做水平轴向周期性往复运动，凸轮连杆推动凸轮滑块做水平轴向周期性往复运动，凸轮连杆通过凸轮运动原理驱动凸轮滑块做上下轴向周期性往复运动。The specific implementation scheme is as follows: the stepping motor pushes the switching valve assembly to move, and the switching valve assembly drives the cam link to slide together; on the cam link, there is a limit sliding groove formed by two connecting rod limit bosses, which is in the ring The cam slider has a slider limit boss that forms a certain angle with the horizontal line, as shown in Figure 5-1 and Figure 5-2. The limit sliding groove will wrap the slider when the cam rod reciprocates in the axial direction. Limiting the boss, and make the cam slider do up and down axial reciprocating movement, so as to realize the stepping motor to push and switch the valve spool assembly to do horizontal axial cyclic reciprocating movement, and the cam connecting rod pushes the cam slider to do horizontal axial reciprocation. Periodic reciprocating movement, the cam connecting rod drives the cam slider to make periodic reciprocating movements in the upper and lower axial directions through the principle of cam movement.
在奶路清洗装置做吸奶动作时，各传动部件处于图5-3的位置A，在奶路清洗装置做清洗奶路动作时，各传动部件处于图5-5的位置C，切换过程需要经过图5-4的位置B，凸轮滑块做其轴向的周期性往复运动时会推动牛奶容器中的插头组件滑动护罩做其轴向的周期性往复运动，而在插头组件滑动护罩内部设有凸起筋位2041，在奶路清洗装置需要清洗奶路***时，会将插头组件滑动护罩推至图5-6所示位置，此时的插头组件滑动护罩内部凸起筋位会迫使牛奶容器插头尾部的弹片2011变形从而压紧牛奶管，这样便保证了本发明的奶路清洗装置在清洗奶路***时，废水不会流入到牛奶瓶中。When the milk path cleaning device is doing the sucking action, the transmission components are in position A in Figure 5-3. When the milk path cleaning device is doing the milk path cleaning action, the transmission components are in the position C in Figure 5-5. The switching process requires After position B in Figure 5-4, the cam slider will push the plug assembly sliding shield in the milk container to make its axial cyclic reciprocating movement when the cam slider does its axial cyclical reciprocating motion, and the plug assembly slides the shield There are raised ribs 2041 inside. When the milk circuit cleaning device needs to clean the milk circuit system, the plug assembly sliding shield will be pushed to the position shown in Figure 5-6. At this time, the plug assembly sliding shield will have internal raised ribs The position will force the elastic sheet 2011 at the end of the milk container plug to deform to compress the milk tube, which ensures that when the milk circuit cleaning device of the present invention cleans the milk circuit system, waste water will not flow into the milk bottle.
当奶路清洗装置要切换到制作牛奶饮品的回路中时，凸轮滑块回到制作牛奶位置，插头组件滑动护罩在牛奶容器中复位弹簧的弹力作用下复位，此时插头组件滑动护罩内部凸起筋位不再对牛奶容器插头尾部的弹片2011施加作用力， 弹片依靠自身弹性变形复位，牛奶管也由封闭状态复位到打开状态，如图5-7所示。从而实现了制作牛奶饮品到清洗牛奶***回路的一整套动作。When the milk circuit cleaning device is to switch to the circuit for making milk drinks, the cam slider returns to the milk making position, and the plug assembly sliding shield is reset under the elastic force of the return spring in the milk container. At this time, the plug assembly sliding shield is inside The raised ribs no longer exert force on the elastic sheet 2011 at the tail of the milk container plug, the elastic sheet is reset by its own elastic deformation, and the milk tube is also reset from the closed state to the open state, as shown in Figure 5-7. Thus, a complete set of actions from making milk beverages to cleaning the milk system circuit is realized.
在奶路清洗装置进行奶路***清洗时，牛奶容器若被用户拔出会导致清洗奶路***的废水通过奶路清洗装置流出到咖啡机外，存在一定安全隐患，所以在清洗牛奶***回路时，牛奶容器与奶路清洗装置必须是紧固连接、不可拆卸，为此，本发明提供一种自锁牛奶容器与奶路清洗装置的方案，实施方案具体如下：在凸轮滑块内部设有可供弹性卡扣运动的轨迹槽53，凸轮滑块在凸轮连杆推动下运动到清洗所需位置时，而此时凸轮滑块两侧的弹性卡扣会嵌在凸轮滑块的内部轨迹槽中，弹簧(B)的复位功能失效，无法收缩也无法弹起，牛奶容器插头与弹性卡扣组成的弹性卡扣在此时变成锁死的卡扣，从而实现了牛奶容器与奶路清洗装置的自锁，保证了咖啡机在清洗奶路***时，废水不会流到咖啡机外侧，排除了清洗用的热水流出危害用户的安全隐患，如图6所示。When the milk line cleaning device is cleaning the milk line system, if the milk container is pulled out by the user, the waste water from cleaning the milk line system will flow out of the coffee machine through the milk line cleaning device. There are certain safety hazards, so when cleaning the milk system circuit The milk container and the milk path cleaning device must be tightly connected and not detachable. For this reason, the present invention provides a self-locking milk container and milk path cleaning device. The specific implementation is as follows: Track groove 53 for the movement of the elastic buckle.
