Abstract

DC60 (21/05/45) The foam dispensing device has a liquid reservoir capable of supplying foam and air or other gases. Its shape-changing design, release device, and handling mechanism for foam production include various mesh screens. When the dispensing device is operating, air from within the device mixes with the foaming liquid. The dispensing device features a flexible, shape-changing seal to allow for rapid air reloading after it has been used in foam creation. Furthermore, the dispensing device utilizes multiple rotating tubes for complete molding, resulting in high-quality, cohesive foam. Used to create foam with excellent texture and quality.

Claims (20)

1. The nozzle for dispensing foam consists of: the foam-generating container; a mixing tube housed within the foam-generating container for mixing the liquid and steam to create foam; the mixing tube has an inlet and outlet; a mesh screen with widely spaced holes to create a turbulent zone is placed in the mixing tube near the outlet; and multiple swirling liquid tubes in contact with the inlet are arranged to direct the flow from the widely spaced mesh screen so that it comes into contact with the liquid and steam to create turbulence and steam flow patterns. The swirling tubes have surface areas and defined openings in contact with the mixing tube inlet and the liquid outlet. The surface area of the multiple tubes has at least one swirling tube in contact with the holes and the steam outlet. Here, steam flows through the swirling tubes and into the holes. 2. The nozzle end of claim 1 additionally comprises: a liquid pipe with an outlet and inlet, a steam pipe with an outlet and inlet, and a vent, each arranged in the foam-generating container; and various mesh screens, including the first screen, and the second screen, arranged for the flow of water from the first screen. 3. The nozzle end of claim 1 additionally comprises: a container with a foam tube; a foam tube for transporting the foam generated in the mixing tube; the foam tube is positioned within the foam tube container and in contact with the mixing tube outlet; and an adapter is connected to the foam tube container. The adapter is sliding and is assembled onto the outlet surface of the foam-generating container for movement between the open and closed positions, where the open position allows contact between air, liquid, and vapor in the container, and the closed position prevents contact between air, liquid, and vapor in the container. 4. The nozzle tip of claim 3 herein, the container with the foam tube, has a protruding seal and at least its notches engage with the outer surface of the container, creating foam when the container with the foam tube is moved between the open and closed positions. 5. The nozzle end of claim 1 additionally includes a check valve positioned in the mixing tube to prevent liquid and foam from flowing back into the container. 6. The nozzle of claim 1 here refers to multiple tubes that rotate completely within the container, creating foam. The section with multiple tubes has a hole in the center, and the surface of the multiple tubes rotates in a swirling motion, which is etched with acid into the contact surface of the hole. Each swirling tube has a main axis. 7. The nozzle tip of claim 6 herein, the swirling tube, uses acid to etch the surface of multiple tubes, swirling within a range of approximately 2 to approximately 50. 8. The nozzle end of claim 1 herein has at least two swirl tubes, and the main axis of at least two swirl tubes is positioned at a right angle to the main axis of the second swirl tube. 9. The foam dispensing nozzle consists of: a foam-generating container with a vent; a mixing tube housed within the container for mixing liquid with steam to create foam; the mixing tube has an outlet and inlet; a mesh screen with evenly spaced gaps to create a turbulent zone is placed in the mixing tube near the outlet; and a movable vent seal that can expand to allow air into the container through the vent. The seal is positioned and movable, interlocking within the foam-generating container for movement between the open, air-entry position and the closed position when foam is released. 10. The nozzle end of claim 9, where the vent seal has a wide end at the top, a protruding edge radially attached to the wide end, and a narrow end at the bottom defining the seal hole, the seal edge interlocking with the bottom surface of the foam-making container, and the bottom end of the seal interlocking with the outer cylindrical wall of the foam-making container. 11. The nozzle end of claim 10 herein, the vent seal, engages with the outer wall of the cylinder at an angle determined by the seal and the outer wall of the cylinder within a range from approximately 35 to approximately 55 degrees, with negative pressure in the container causing the seal to move away from the outer wall, allowing air to enter the container. 12. The nozzle end of claim 9 here has a conical vent seal. 13. The nozzle end of claim 9 herein, a deformable, flexible ring with a common center, is positioned on the outside of the mixing tube and adjusted to interlock with the vent seal and is shaped to allow movement between the open and closed positions; the open position for interlocking with at least one portion of the deformable seal has a first flexible characteristic; the closed position for pressing the first flexible deformable seal against the underside of the foam-generating container. 14. The nozzle end of claim 13 herein, the seal is deformable, flexible, and ring-shaped, molded completely inside the foam-generating container near the bottom surface. 15. The nozzle end of claim 3, additionally, includes: a vent seal that can change shape and expand to allow air into the container through the vent; the seal is positioned and movable, interlocking inside the foam-generating container for movement between the open, air-intake position and the closed position when foam is released; the container has a neck for filling with liquid, providing foam and vapor vents, and the filling container is assembled to the foam-generating container via the neck. 16. The foam dispensing device of claim 15 herein, the foam tube container, has protruding parts and at least one main contact point positioned to engage with the outer surface of the container, creating foam when the foam tube container is moved between the open and closed positions. 17. Foam dispensing device 15. Here, the vent seal has a wide top end, a radially protruding edge attached to the wide end, and a narrow bottom end restricting the seal opening. The seal edge engages with the bottom surface of the foam-making container, and the bottom end of the seal engages with the outer wall of the foam-making container at an angle determined by the seal and the outer cylindrical wall within approximately 35 to 55 degrees. The negative pressure within the container causes the seal to move away from the outer wall, allowing air to enter the container. 18. The foam dispensing device of claim 15 herein, the container has a threaded connection for screwing onto the foam-generating container. 19. Foam dispensing device of claim 15. Here, foam is dispensed by increasing pressure in a container. 20. Foam dispensing device of claim 15. Herein, a container is made of a flexible polymer material, and foam is dispensed by applying pressure into the container, thereby deforming the container.
