摘要： A push-to-connect fitting is provided. The push-to-connect fitting includes a connector body, a sealing member, a grab ring, a cartridge, a retainer sleeve, a plurality of latches, and an interference portion. The sealing member is configured to form a sealing engagement with a fluid conduit. The grab ring includes a plurality of teeth configured for coupling to the fluid conduit. The retainer sleeve is received over at least part of the cartridge and is received over at least part of the connector body. The plurality of latches are located on the retainer sleeve and are configured to secure the retainer sleeve to the connector body to facilitate retention of the sealing member, the grab ring, and the cartridge. The interference portion is configured to engage the retainer sleeve to substantially prevent rotation of the retainer sleeve relative to the connector body.

摘要： A quickconnect structure having a fitting connector, a connector, and U-shaped positioning snap pin. The fitting connector has a connector part, a fitting connector body part coupled to the connector part, and a fitting part coupled to the fitting connector. The connector part, the fitting connector body part, and the fitting part define a fitting hole extending therethrough, and the fitting part defines positioning groove, a longitudinal snap hole, and a side snap opening in communication with the longitudinal snap hole. The connector has a connection end, a connector body part coupled to the connection end, and a positioning bump. The connection end and the connector body part define a duct hole extending therethrough, the connection end defines a positioning snap groove, and the fitting connector is configured to accept the connection end in the fitting hole. When the connection end is fully inserted into the fitting connector, the positioning bump is located in the positioning groove, and the longitudinal snap hole is aligned with the positioning snap groove. The U-shaped positioning snap pin has a pin base, a pin body part coupled to the pin base, and a snap protrusion coupled to the pin body part. The U-shaped positioning snap pin is configured to be partially inserted and fully inserted into the longitudinal snap hole; when partially interested, the snap protrusion engages the side snap opening and the connector is able to be inserted into the fitting connector; and when fully inserted and when the connector is inserted into the fitting connector, the pin body part engages the positioning snap groove and the snap protrusion engages a longitudinal snap hole exit.

摘要： The T-head coupler is intended to perform a cleaning-in-place of a blackwater tank inside a recreational vehicle, using a mixture of water and a cleaning agent. To accomplish this, the device includes a unique arrangement of ports and distribution channels, wherein the ports on the device are designed specifically to couple with ports commonly found in RVs and water sources. In addition, a container filled with a cleaning agent is attached to the bottom port on the device. When all attachments are made, a plurality of channels within the device direct incoming water to the container. The water mixes with the cleaning agent inside the container, forming a cleaning solution. The cleaning solution flows out of the device, using the pressure from the water source. The cleaning solution then flows from the RV port and into the blackwater tank, thereby cleaning the tank.

摘要： A chemical liquid dilution system includes a first material offering device providing fluid, a second material offering device, and a mixing device. The second material offering device provides liquid. The mixing device includes a fluid mixer, a first connection port, a second connection port, and an output port. The fluid mixer has a fluid limiting channel with an interface communicating with the first connection port and another interface communicating with the second connection port and the output port. The first connection port is connected to the first material offering device. The second connection port is connected to the second material offering device. After the fluid passes through the first connection port and the fluid limiting channel, the fluid and liquid are mixed up to form a diluted chemical liquid, and the output port discharges the diluted chemical liquid. A chemical liquid dilution method is also disclosed.

摘要： A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.
