本发明实施例提供的智能空压机压力罐自动排水装置中的上述一个或多个技术方案至少具有如下技术效果之一：本发明实施例的智能空压机压力罐自动排水装置，由滤杯、电磁阀和控制机构组成，滤杯的侧壁上安装有一个控制盒本体，控制盒本体内分别安装有第一检测端子和第二检测端子，第一检测端子设置在第二检测端子的上方，空压机的出水口和滤杯连通，那么空压机排出的水分就会储存在滤杯内，随着水量的增加，水位会不断上升，当水位上升至第二检测端子的位置的时候，第二检测端子收到信号，并将信号传递给PCB板，这时PCB板控制电磁阀打开，滤杯内部的水分就会自动排出，实现水分的自动化排出，当电磁阀打开并且水分在排出的瞬间，由于滤杯的容积是相对固定的，那么PCB板通过工程人员设定的程序进行精密计算，这样能够使得每次排水之后液面都能下降到设定的高度，这样有利于保证水分能够顺利地进入滤杯或者从滤杯内排出，因为液面每次下降的高度都是通过程序精密计算的，这样可以防止滤杯内的压缩气体大量损失，在水分排出的过程中会泄除滤杯内的压力，使得每次排水之后滤杯内的压力都能得到释放，实现高位排水功能，(也就是说泄除了滤杯内的压力之后，空压机内的水分能被压力压进设置在高位置处的滤杯内，从而实现高位排水功能)，当排水完成时，PCB板就会控制电磁阀关闭，此时排水过程结束，本装置无需通过人工方式进行操作，避免繁琐的过程，有利于实际生产，提高生产效率。

在本发明的一个实施例中，如图1～3所示，提供一种智能空压机压力罐自动排水装置，包括滤杯10、电磁阀20和控制机构30；所述滤杯10的顶部与空压机的出水口连接以用于收集水分，所述控制机构30包括控制盒本体31、第一检测端子32、第二检测端子33和PCB板34，所述控制盒本体31与所述滤杯10的侧壁固定连接，所述PCB板34固定连接于所述控制盒本体31的内部，所述第一检测端子32和所述第二检测端子33均与所述PCB板34电性连接，且所述第一检测端子32和所述第二检测端子33分别设于所述控制盒本体31的竖直方向上，所述电磁阀20与所述PCB板34电性连接，且所述电磁阀20设于所述滤杯10的底部以用于自动排出所述滤杯10内部的水分。
具体地，本发明实施例的智能空压机压力罐自动排水装置，由滤杯10、电磁阀20和控制机构30组成，滤杯10的侧壁上安装有一个控制盒本体31，控制盒本体31内分别安装有第一检测端子32和第二检测端子33，第一检测端子32设置在第二检测端子33的上方，空压机的出水口和滤杯10连通，那么空压机 排出的水分就会储存在滤杯10内，随着水量的增加，水位会不断上升，当水位上升至第二检测端子33的位置的时候，第二检测端子33收到信号，并将信号传递给PCB板34，这时PCB板34控制电磁阀20打开，滤杯10内部的水分就会自动排出，实现水分的自动化排出，当电磁阀20打开并且水分在排出的瞬间，由于滤杯10的容积是相对固定的，那么PCB板34通过工程人员设定的程序进行精密计算，这样能够使得每次排水之后液面都能下降到设定的高度，这样有利于保证水分能够顺利地进入滤杯10或者从滤杯10内排出，因为液面每次下降的高度都是通过程序精密计算的，这样可以防止滤杯10内的压缩气体大量损失，在水分排出的过程中会泄除滤杯10内的压力，使得每次排水之后滤杯10内的压力都能得到释放，实现高位排水功能，(也就是说泄除了滤杯10内的压力之后，空压机内的水分能被压力压进设置在高位置处的滤杯10内，从而实现高位排水功能)，当排水完成时，PCB板34就会控制电磁阀20关闭，此时排水过程结束，本装置无需通过人工方式进行操作，避免繁琐的过程，并且空压机内产生的积水通过自动化的方式进行排放，无需依赖传统人工手动控制的方式解决，有利于实际生产，提高生产效率。
具体地，传统的用在空压机上的排水设备，其排水方式是使用计时器，不通过精密计算的，每过一段时间就会自动进行排水，即使滤杯10内的水位没有上升到感测位置也会自动进行排水，(也就是说经过设定的时间就会自动排水，一、若时间计算错误，不能精确地排出滤杯10内的水分，多余的水分就会残留在空压机及储气桶内，导致空压机及储气桶内产生积水并导致锈蚀的现象，从而产生锈泥，这样容易造成电磁阀20的堵塞)，二、若时间计算错误，电磁阀20仍然会长期不间断地工作，很容易会造成阀体的损坏，并且空压机内的压缩气体容易大量损失，浪费能源。
在本发明的另一个实施例中，如图1～3所示，所述第一检测端子32和所述第二检测端子33均为感应铜片。具体地，将第一检测端子32和第二检测端子33直接固定在控制盒本体31内部的竖直方向上，控制盒本体31是非金属不导 电的材质，然后将控制盒本体31固定在滤杯10的侧壁上，由于水高度的面积会与第一检测端子32和第二检测端子33分别产生电容感应量，所以当水面上升时，水高度会产生电容感应量，根据电容感应量进行数字转换，因此当被测的水位上升到对应的第一检测端子32或者第二检测端子33的高度时，水的高度就会被检测出来，感应铜片的传导性能较好，有利于信号地精确传播与接收，从而提高检测精度。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于手动排水的排水机构40；所述排水机构40包括排水接头41和泄水顶针42，所述排水接头41与所述电磁阀20的出水口(图未示)连通，所述泄水顶针42设于所述排水接头41的底部并与所述电磁阀20的出水口活动连接。具体地，电磁阀20的出水口和一个排水接头41连通，滤杯10内的水可以通过电磁阀20的控制得以排出，为了防止电磁阀20故障而不能正常排水的现象发生，在排水接头41的转角处设置了一个泄水顶针42，泄水顶针42和电磁阀20的出水口连接，拉动或者推动泄水顶针42，泄水顶针42就会挤压电磁阀20的出水口，那么滤杯10内的水即可继续流出，防止滤杯10内部压力过大从而导致滤杯10的炸裂，提高了安全性能。
在本发明的另一个实施例中，如图1～3所示，所述排水接头41采用橡胶材料制成。具体地，排水接头41采用橡胶材料制成，长期接触水分也不容易腐蚀，比传统的金属材质的排水接头41寿命更长，排水接头41属于卡套式水管接头的类型，能将无螺纹的电磁阀20与排水接头41连接，省却套丝工序，只需将电磁阀20旋入即可，装配之后结构紧密，强度高，不容易发生松动。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于过滤水中杂质的过滤机构50；所述过滤机构50包括滤网托架51和滤网52，所述滤杯10包括杯体11和杯盖12，所述滤网托架51设于所述杯体11与所述杯盖12之间的连接处，且所述滤网托架51位于所述第一检测端子32的上方，所述滤网52设于所述滤网托架51的中心位置处。具体地，杯 体11和杯盖12之间安装有一个滤网托架51，滤网托架51的中心处安装有一个滤网52，滤网52刚好位于空压机的出水口下方，那么空压机的出水口排出的水进入杯体11之前，首先要经过滤网52，这样能够有效地去除水中的杂质，防止杯体11的堵塞，(传统的滤网52中用于过滤水分的面积过小，导致过滤水分的效率降低)，杯体11和杯盖12均采用透明材料制成，有利于工人人员观察杯体11和杯盖12的内部情况，在发生故障的时候，工人可以观察内部情况从而快速诊断出故障问题，便于进行维修工作。
在本发明的另一个实施例中，如图1～3所示，所述杯体11上对应所述滤网托架51的位置开设有卡槽111；所述滤网托架51与所述卡槽111紧配连接。具体地，滤网托架51和滤网52之间紧配连接，滤网托架51与卡槽111也是紧配连接，这样安装与拆卸滤网52或者滤网托架51都可以快速进行，相对于传统的使用螺钉紧固的滤网52，大幅度提高了维修效率，可以快速恢复生产。
在本发明的另一个实施例中，如图1～3所示，所述卡槽111呈“O”形状设置。具体地，卡槽111呈“O”形状设置，滤网托架51呈圆形状设置，滤网托架51的外周轮廓刚好和卡槽111的内壁卡接适配，这样既可实现滤网托架51地快速安装和拆卸，并且能够防止滤网托架51偏移，避免了杂质从滤网托架51和杯体11之间的缝隙流入本体内部。
在本发明的另一个实施例中，如图1～3所示，所述杯体11与所述杯盖12之间通过若干螺钉可拆卸连接。具体地，杯体11与杯盖12之间通过多个螺钉可拆卸连接，本装置共设有七个螺钉，并且设置有相应的七个螺母分别与七个螺钉螺纹连接，选下七个螺钉之后，将杯盖12拆卸之后，即可方便地更换杯体11内的滤网52，防止滤网52因堵塞而造成排水异常的现象发生。
在本发明的另一个实施例中，如图1～3所示，所述杯体11与所述杯盖12之间还设有用于防止漏水的滤杯密封圈91a；所述滤杯密封圈91a与所述滤网托架51均呈圆形状设置，且所述滤杯密封圈91a的直径大于所述滤网托架51的直径。具体地，杯体11与杯盖12之间还套设有一个滤杯密封圈91a，滤杯密封 圈91a和滤网托架51均呈圆形状设置，并且滤杯密封圈91a的直径大于滤网托架51的直径，那么就是说滤杯密封圈91a套设在滤网托架51的外周，那么空压机排出的水经过滤网托架51的时候，如果滤网托架51不能瞬间将水排入杯体11内而导致水分发生溅散，那么滤杯密封圈91a也可以防止水分直接从杯体11与杯盖12之间的缝隙渗出，有效地防止漏水的现象发生。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于与空压机的出水口连接的连接机构60；所述连接机构60设于所述杯盖12的顶部与空压机的出水口之间，所述连接机构60包括连接座61、进水接头62和螺母63，所述连接座61与所述杯盖12螺纹连接，所述进水接头62与所述连接座61的上端螺纹连接，所述螺母63与所述连接座61的下端螺纹连接。具体地，杯盖12的顶部安装有一个连接座61，连接座61从上往下旋进杯盖12，并且穿过杯盖12的底部之后与螺母63螺纹连接，这样就可以将连接座61牢固地安装在杯盖12上，在连接座61的顶部安装有一个进水接头62，这样就可以将进水接头62牢固地安装在连接座61的顶部，进水接头62与空压机的出水口连接的时候，就能够保持稳定的进水。
在本发明的另一个实施例中，如图1～3所示，所述连接座61与所述杯盖12之间设有用于防止漏水的进水接头密封圈92a。具体地，连接座61和杯盖12之间安装有一个进水接头密封圈92a，这样可以防止水分进入杯盖12之后，水分受到压力，从连接座61和杯盖12之间的缝隙渗出到外界，有效地防止漏水的现象发生。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于连接外部设备的安装支架70；所述安装支架70设于所述连接座61与所述杯盖12之间。具体地，连接座61与杯盖12之间安装有一个安装支架70，安装支架70通过连接座61紧固在杯盖12的顶部，将安装支架70和空压机的侧壁连接，即可固定本产品，防止本产品发生抖动，从而提高检测精度。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于锁紧所述电磁阀20的锁紧座80；所述锁紧座80的外圈与所述杯体11的底部螺纹连接，所述锁紧座80的内圈与所述电磁阀20螺纹连接。具体地，杯体11的底部安装有一个锁紧座80，锁紧座80从上往下旋进杯体11，并且穿过杯盖12的底部之后与电磁阀20实现螺纹连接，这样就可以将电磁阀20牢固地安装在杯体11的底部，防止电磁阀20掉落的现象发生。
在本发明的另一个实施例中，如图1～3所示，所述锁紧座80与所述杯体11之间设有用于防止漏水的锁紧密封圈93a。具体地，锁紧座80和杯体11的底部之间安装有一个锁紧密封圈93a，锁紧密封圈93a可以防止杯体11内的水分从锁紧座80和杯体11之间的缝隙渗出到外界，有效地防止漏水的现象发生。
在本发明的另一个实施例中，如图1～3所示，所述智能空压机压力罐自动排水装置还包括用于指示工作状态的指示灯组件90。具体地，控制盒本体31内安装有指示灯组件90，指示灯组件90可以显示当前工作状态，有利于工人判断本产品是否正常运作。
在本发明的另一个实施例中，如图1～3所示，所述指示灯组件90包括电源指示灯91、故障指示灯92和排水指示灯93；所述电源指示灯91、所述故障指示灯92和所述排水指示灯93均设于所述控制盒本体31内，且所述电源指示灯91、所述故障指示灯92和所述排水指示灯93均与所述PCB板34电性连接。具体地，指示灯组件90由电源指示灯91、故障指示灯92和排水指示灯93构成，并且电源指示灯91、故障指示灯92和排水指示灯93均和PCB板34电性连接，当本产品通电的时候，电源指示灯91就会亮起，当空压机开始排水，杯体11内的水位上升并且来到第一检测端子32的位置的时候，排水指示灯93就会亮起，然后PCB板34就会指示电磁阀20打开通道并实现排水，当杯体11内的水位上升超过第一检测端子32的位置，并且来到第二检测端子33的位置的时候，故障指示灯92就会亮起，这时工人根据亮起的灯光可以得知本产品发生故障不能排水，需要通过手动的方式来挤压泄水顶针42来自动排水，PCB板34上集 成有WIFI功能，通过移动终端连接WIFI，可以实现实时的数据监控，并有利于工作数据的记录，以便工作人员更好地使用本产品。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
