Description

Technical Field

[0001] This utility model relates to the field of metal pull-out head technology, specifically a dual-waterway horizontal metal pull-out head. Background Technology

[0002] Currently, most faucet pull-out heads on the market are made of plastic, which has a poor texture and cannot be customized in various colors to meet customer needs, making it difficult to satisfy the demands of high-end and mid-range customers both domestically and internationally. While some pull-out heads have metal outer shells, the internal water-passing parts are made of plastic. This requires significant upfront investment in molds, and it is also very difficult for these internal plastic water-passing parts to meet various international certification requirements.

[0003] A three-in-one dual-water-path horizontal pull-out head has one water path that outputs mixed hot and cold water, and another that outputs pure water. The two water paths must be completely isolated. Its water path structure is much more complex than that of a single-water-path pull-out head, involving more sealing and connection structures. Traditional plastic pull-out head structures can hardly meet this structural requirement, and plastic molds cannot be formed. Utility Model Content

[0004] The purpose of this invention is to provide a dual-waterway horizontal metal pull-out head to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-channel horizontal metal pull-out head includes a lateral pull-out head, a check valve fixedly installed on the inner side of the lateral pull-out head, a check valve connecting shaft fixedly installed on the inner side of the lateral pull-out head, a dual-channel pull-out hose horizontally snapped onto the inner side of the lateral pull-out head, an aerator connecting shaft fixedly snapped onto the inner side of the lateral pull-out head, an O-ring fixedly snapped onto the bottom end of the lateral pull-out head, a dual-channel aerator fixedly connected to the bottom end of the lateral pull-out head, and a connector fixedly connected to the bottom end of the lateral pull-out head.

[0007] As a preferred embodiment of this utility model: the side pull-out head includes a pull-out head body, a pull-out head connector, a cover plate and a bubbler connector. The pull-out head body is a machined part, a precision casting, or a forging, and both sides of the interior have a concave structure design.

[0008] In a preferred embodiment of this utility model, the check valve is installed on the inner side of the check valve connecting shaft and is fixed in the inner cavity of the shower head by means of threads.

[0009] In a preferred embodiment of this utility model, one end of the check valve connecting shaft is connected to one end of the dual-channel pull-out hose, and the other end is connected to the metal shower head thread. The connection between the two ends is sealed with an O-ring, thereby forming an independent water purification channel.

[0010] As a preferred embodiment of this utility model: the dual-channel pull-out hose is a hose that simultaneously provides hot and cold water channels and purified water channels. It is threadedly connected to the side pull-out head, and the intermediate joint is assembled and connected to the check valve connecting shaft. One end of the aerator connecting shaft is connected to the side pull-out head body and the aerator. The connection is sealed with an O-ring 6.

[0011] As a preferred embodiment of this utility model: the dual-channel aerator is an aerator that simultaneously provides hot and cold water channels and clean water channels. Hot and cold water flow out from the periphery of the aerator, and clean water flows out from the central hole of the aerator.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The advantages of this product:

[0014] The all-metal structure of the water-passing shell reduces certification difficulty; the designed check valve connecting shaft 3 and aerator connecting shaft 7 act as a "bridge" in the pull-out head structure, greatly simplifying the overall water circuit structure; the concave structures on both sides of the pull-out head body ensure that the overall weight of the pull-out head does not exceed 170g, and the pull-out and reset are smooth; the cleverly designed machining holes of the hot and cold water channels directly "intersect" with the aerator outlet holes, becoming the outflow channel for hot and cold mixed water, and the seemingly complex water circuit structure can be achieved through simple machining. It does not require a large investment in plastic molds; it is easy to pass various certifications; the pull-out head has a better texture and is easier to design for different color requirements. The technical solution of this invention can solve the following defects and problems existing in the prior art: the pull-out head is designed as an all-stainless steel (not limited to stainless steel) structure, and several metal parts are combined into one piece through welding, precision casting, forging, etc., so that except for the sealing rubber parts and the aerator, all other water-passing parts are made of metal. The metal material can meet the requirements of different customers for various colors and processes on the product surface, and a high-quality surface effect can be easily achieved. At the same time, the products are more likely to pass various certifications abroad. Attached Figure Description

[0020] Please see Figure 1-3 In this embodiment of the utility model, a dual-channel horizontal metal pull-out head includes a side pull-out head 1. A check valve 2 is fixedly installed on the inner side of the side pull-out head 1. A check valve connecting shaft 3 is fixedly installed on the inner side of the side pull-out head 1. A dual-channel pull-out hose 4 is horizontally snapped onto the inner side of the side pull-out head 1. An aerator connecting shaft 5 is fixedly snapped onto the inner side of the side pull-out head 1. An O-ring 6 is fixedly snapped onto the bottom end of the side pull-out head 1. A dual-channel aerator 7 is fixedly connected to the bottom end of the side pull-out head 1. A connector 8 is fixedly connected to the bottom end of the side pull-out head 1. The side pull-out head 1 consists of a pull-out head body, a pull-out head connector, a cover plate, and an aerator connector. The pull-out head body is a machined part, a precision casting, or a forging. Both sides of the interior have a concave structure design. The return valve 2 is installed on the inner side of the check valve connecting shaft 3 and is fixed in the inner cavity of the shower head by threads. One end of the check valve connecting shaft 3 is connected to one end of the dual-channel pull hose 4, and the other end is connected to the metal shower head thread. The connection between the two ends is sealed with O-rings 6, thus forming an independent clean water channel. The dual-channel pull hose 4 is a hose that provides both hot and cold water and clean water channels at the same time. It is threaded to the side pull head 1, and the middle connector is assembled and connected to the check valve connecting shaft 3. One end of the aerator connecting shaft 5 is connected to the body of the side pull head 1 and the aerator. The connection is sealed with O-rings 6. The dual-channel aerator 7 is an aerator that provides both hot and cold water and clean water channels at the same time. Hot and cold water flow out from the periphery of the aerator, and clean water flows out from the center hole of the aerator.

[0021] The working principle of this utility model is as follows:

[0022] The side-pull head—one of the core components—comprises the pull head body, pull head connector, cover plate, and aerator connector. The pull head body can be machined, precision-cast, or forged. Its internal concave design on both sides not only meets specific water circuit requirements but also significantly reduces the weight of the pull head, ensuring smooth pull-out and return. The check valve—installed in the connecting shaft 3 and threaded into the shower head's inner cavity—prevents siphoning from the pull head. The check valve connecting shaft—another core component—connects one end to the dual-channel pull hose 5 and the other end to the metal shower head thread. O-rings seal the connection points, creating independent purified water channels. The dual-channel pull hose—a hose providing both hot and cold water and purified water channels simultaneously—is threaded to the side-pull head 1. The intermediate connector is assembled with the connecting shaft 3, serving as the purified water outflow channel. Hot and cold water flow out from the outside of the hose and through a special channel in the pull head body. The aerator connecting shaft—one of the core components—connects the pull-out head body to the aerator, serving as the end of the purified water outflow channel. The connection is sealed with an O-ring 6. O-rings—installed at both ends of the aerator connecting shaft—ensure complete isolation between the purified water channel and the hot and cold water channels. The dual-channel aerator—a type of aerator that simultaneously provides hot and cold water and purified water channels; hot and cold water flow from the periphery of the aerator, while purified water flows from the central hole. The all-metal structure of the water-passing shell reduces certification difficulty. The designed check valve connecting shaft 3 and aerator connecting shaft 7 act as a "bridge" in the pull-out head structure, greatly simplifying the overall water circuit structure. The concave structures on both sides of the pull-out head body ensure that the overall weight of the pull-out head does not exceed 170g, ensuring smooth pull-out and reset. The cleverly designed machining holes for the hot and cold water channels directly "pierce" the aerator's outlet hole, becoming the outflow channel for the mixed hot and cold water, achieving a seemingly complex water circuit structure through simple machining.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
