Description

Technical Field

[0001] This utility model belongs to the field of bathroom products, specifically relating to a multi-level shower water path switching device. Background Technology

[0002] Current shower products can mix hot and cold water and supply it from different outlets. These outlets connect to fixed shower heads, portable shower heads, and other water pipes to meet user needs. The mixing of hot and cold water and the switching of water outlets require a water circuit switching device. Existing water circuit switching devices include a main body, water circuits machined within the main body, and on / off control valves and switching valves installed on the water circuits to control the mixing of hot and cold water and the switching of water outlets.

[0003] For example, the shower controller body disclosed in patent application CN202020977482.7, and the multi-level shower controller disclosed in patent application CN201720038044.2, have complex water circuit structures inside the body, making them difficult to process. Currently, the common processing method is to first form the body as a whole by die casting, and then use a machining center to precision machine the internal water circuits and chambers. This is also the mainstream processing technology at present, which leads to high processing costs and does not meet production requirements. Utility Model Content

A switching chamber 2031 is opened on the front end face of the second cylinder 203. The rear end face of the column 203 has a top spray interface chamber 2032 that communicates with the switching chamber 2031. The outer side of the second cylinder 203 near the front end face is provided with a boss 204.

The switching chamber 2021 and the switching chamber 2031 are connected through a mixing channel 2012.

[0030] The hot water channel 2011 is arranged horizontally, extending to the left and connecting to the lower half of the hot water interface chamber 2041. The connecting channel 2013 is arranged front-back, with its front end connecting to the switch chamber 2021. The connecting channel 2021 is perpendicular to the hot water channel 2011 but not on the same horizontal plane. The rear end of the connecting channel 2013 connects to the right end of the hot water channel 2011 and to the vertically extending first passage 2023.

[0031] Hot water channel 2011, mixing channel 2012, connecting channel 2013, and first passage 2023 are cylindrical channels. The connecting water passages between the switching chamber 2021 and the cold water interface chamber 2022, the switching chamber 2031 and the top spray interface chamber 2032, the lower water outlet pipe chamber 2033 and the switching chamber 2031, and the hot water interface chamber 2041 and the switching chamber 2031 are all cylindrical channels.

[0032] The hot water channel 2011, the mixing channel 2012 and the first passage 2023 have locking threads at their outer end openings, and sealing bolts are connected to the locking threads. The sealing bolts can seal the hot water channel 2011, the mixing channel 2012 and the first passage 2023.

[0035] The main body 2 is preferably made of aluminum profile, such as an aluminum block. The outline of the main body 2 can be quickly milled using a machining center. The switch chamber 2021, switching chamber 2031, cold water interface chamber 2022, hot water interface chamber 2041, and lower water outlet pipe chamber 2033 on the main body 2 can be directly drilled and milled. The connecting water passages between the switch chamber 2021 and the cold water interface chamber 2022, the switching chamber 2031 and the top spray interface chamber 2032, the lower water outlet pipe chamber 2033 and the switching chamber 2031, and the hot water interface chamber 2041 and the switching chamber 2031 can also be directly drilled and milled using a machining center. The hot water channel 2011, the mixing channel 2012, and the first passage 2023 can also be drilled and milled using a machining center.

[0036] The working process of this utility model is as follows: In use, hot water enters the hot water channel 2011 through the hot water interface pipe 4, and then enters the switch chamber 2021 through the first passage 2023 and the connecting passage 2013. Cold water enters the cold water interface chamber 2022 through the cold water interface pipe 3, and then enters the switch chamber 2021. The switch control valve 7 controls the opening and closing of the cold water circuit and the hot water circuit. Rotating the switch control valve 7 can control the flow rate of cold water and hot water. After passing through the switch control valve 7, the cold and hot water enter the mixing channel 2012 and then enter the switching chamber 2031. The switching valve device 8 controls the opening and closing between the switching chamber 2031 and the top spray interface chamber 2032, the lower water outlet pipe chamber 2033 and the switching chamber 2031, and the hot water interface chamber 2041 and the switching chamber 2031, thereby controlling the water output of the top spray interface pipe 5, the lower water outlet pipe device 6 and the hand spray interface 205.

[0037] It should be noted that the switch control valve 7 and the switching valve device 8 are common components currently on the market, and appropriate models and specifications can be selected according to design requirements. Therefore, the structure and working principle of the switch control valve 7 and the switching valve device 8 will not be described in detail. The general structural design of the switch chamber 2021 that cooperates with the switch control valve 7 and the switching chamber 2031 that cooperates with the switching valve device 8 is also a conventional design, and the specific fitting tolerances, connection accuracy and other detailed parameters will not be elaborated.

[0038] The preferred models of the switch control valve 7 are: T3001-2 switch valve and T3005 switch valve;

[0039] The preferred model of the switching valve device 8 is the T2604 switching valve. Example 2

[0040] The same structure as in Embodiment 1 will not be described again. The top spray interface chamber 2032 is located on the cylindrical surface near the rear end of the second cylinder 203. The top spray interface chamber 2032 opens upward and communicates with the switching chamber 2031. The switching chamber 2031 is provided with a first water outlet 206 with an outward opening. The connecting water passage between the switching chambers is a cylindrical channel.

[0041] The operating levers of the switch control valve 7 and the switching valve device 8 are connected to an adapter rod 9. The purpose of the adapter rod 9 is to allow for flexible adjustment of the size of the main body 2. In actual production, in order to reduce costs, the actual size of the main body 2 is designed to be relatively small, while in order to ensure the overall aesthetics of the device, the size of the outer shell 1 needs to be designed to be relatively large. This would cause the switch control valve 7 and the switching valve device 8 to be incompatible with the outer shell 1. The adapter rod 9 solves this problem, allowing the main body 2 to be made as small as possible, while the size of the outer shell 1 is not limited.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
