Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a stainless steel shower faucet. Background Technology

[0002] As a key component of modern bathroom fixtures, the materials and structural design of shower faucets directly affect their lifespan, safety, and user experience. Currently, shower faucets on the market are mainly made of copper, zinc alloy, and plastic. Copper shower faucets have drawbacks such as higher cost and the electroplating layer easily peeling off over time. Zinc alloy shower faucets are die-cast, resulting in lower cost; however, due to the brittle nature of zinc alloy, they are prone to cracking under prolonged stress, exhibiting insufficient strength and poor corrosion resistance. Plastic shower faucets are injection-molded, making them lightweight and inexpensive, but they are prone to aging and have poor sealing properties.

[0003] Based on the above situation, the market has begun to focus on stainless steel shower faucets. Stainless steel has excellent corrosion resistance and strength; however, due to its inherent material properties, stainless steel has high hardness and low thermal conductivity, making it difficult to process. Chinese patent document CN202321550122.9 discloses a shower faucet that uses a split stainless steel welded structure to replace the original copper alloy or steel casting structure. The shower faucet includes a valve body 100 and two thin-walled shells 200, which are symmetrically arranged on both sides of the valve body and welded together with the valve body 100. The faucet structure design is relatively complex, and the two thin-walled shells 200 require precise alignment welding. The assembly steps are cumbersome and inefficient, and the high rate of assembly defects due to welding heat deformation can easily lead to sealing performance defects.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues and proposed a stainless steel shower faucet that overcomes the above-mentioned technical defects, thus giving rise to this case. Utility Model Content

Detailed Implementation

[0030] The following detailed description of this case is provided in conjunction with the accompanying drawings and specific embodiments.

[0031] This case involves a stainless steel shower faucet, such as Figure 1-7 As shown, it includes a hollow body 1, a valve body 2, and two end plates 3.

[0032] The hollow body 1 has openings 11 at both ends and a mounting hole 12 in the middle. The valve body 2 has a welded part 21 that is inserted into the mounting hole 12 and internally welded to the inner wall of the hollow body 1, and a main body part 22 located outside the mounting hole 12. The two end plates 3 are matched and welded to the openings 11 at both ends of the hollow body 1. A sealed first water passage cavity 13 and a second water passage cavity 14 are formed on both sides of the hollow body 1 corresponding to the welded part 21.

[0033] In this new type of shower faucet, the valve body 2 is directly embedded into the mounting hole 12 of the hollow body 1. The valve body 2 is fixed to the inner wall of the hollow body 1 by internal welding through its welding part 21. The internal welding can be carried out by high-power laser welding, which can ensure that the root of the weld is completely fused and that the welded part does not leak any medium during long-term use. The welding firmness is improved, the tensile strength of the weld is increased, the sealing performance is excellent, and a zero-leakage sealing effect is achieved.

[0034] The weld seam of the welded part 21 of the new valve body 2, which is internally welded to the hollow body 1, is hidden inside the hollow body 1. In actual production, there is no need to polish the outer surface of the valve body 2 and the hollow body 1. This not only saves polishing costs and improves production efficiency, but also enhances the surface consistency of the faucet, thereby ensuring the quality and aesthetic appearance of the product.

[0035] This new type of structure is a single hollow body structure, which only requires welding a single hollow body 1 to the valve body 2. Compared with the existing technology that uses two shells to weld to the valve body, this new type simplifies the structural design, reduces the assembly process in actual production, eliminates assembly errors, and greatly improves assembly efficiency and welding qualification rate.

[0036] This new type of stainless steel shower faucet is made entirely of stainless steel, offering excellent overall corrosion resistance. The various components, especially the one-piece hollow body, can be precision-stamped in a single process, resulting in not only a more aesthetically pleasing appearance but also improved corrosion resistance and sealing performance.

[0037] The mounting hole 12 is a straight-edged circular hole composed of two equal-radius arc segments 121 and two parallel straight line segments 122, with the two equal-radius arc segments 121 facing the directions of the two end openings 11 respectively. The welding part 21 is a circular part, and the outer surface of the circular part has two planes 211 corresponding to the two parallel straight line segments 122. The structural design of the mounting hole 12 and the welding part 21 facilitates the positioning and stable assembly between the two, and also provides operational convenience for the internal welding and fixing of the welding part 21 and the hollow body 1.

[0038] Furthermore, the insertion end 212 and the two planes 211 of the welding part 21 are in contact with the inner wall of the hollow body 1; two sets of closed-loop welds 20 are formed between the hollow body 1 and the welding part 21, located inside the hollow body 1 and opening towards the two ends respectively. The closed-loop weld 20 includes two parallel segments of equal-radius circular arc welds 201 and two parallel straight welds 202 that connect the two segments of equal-radius circular arc welds 201 in a closed loop. The two sets of closed-loop welds 20 are ingeniously designed to ensure that the welding part 21 and the hollow body 1 form an integral airtight welding structure, ensuring that the first water passage cavity 13 and the second water passage cavity 14 have excellent and durable airtight performance.

[0039] The hollow body 1 is provided with a first connecting hole 15 communicating with the first water passage cavity 13 and a second connecting hole 16 communicating with the second water passage cavity 14. A first water inlet connector 4 and a second water inlet connector 5 are respectively welded to the first connecting hole 15 and the second connecting hole 16. Thus, the stainless steel shower faucet has two water inlet connection ends for connecting hot and cold water respectively.

[0040] Furthermore, the first water inlet connector 4 has an internal thread 41 machined inside, and the second water inlet connector 5 has an internal thread 51 machined inside. During application and installation, the internal threads enable easy installation of the shower faucet to the hot and cold water ends.

[0041] The valve body 2 is provided with a valve core groove 23, a first water inlet hole 24, a second water inlet hole 25, and a water outlet hole 26, all of which are connected to the valve core groove 23. The first water inlet hole 24 is connected to the first water passage chamber 13, and the second water inlet hole 25 is connected to the second water passage chamber 14. With the valve core installed in the valve core groove 23, hot and cold water enter the valve body 2 through the first water inlet hole 24 and the second water inlet hole 25, respectively. After flowing through the valve core, the mixed water flows out from the water outlet hole 26, thus realizing the faucet water flow.

[0042] In a further embodiment, the stainless steel shower faucet also includes a water outlet connector 6. The hollow body 1 is provided with a through hole 17 corresponding to the water outlet 26. The water outlet connector 6 passes through the through hole 17 and is connected to the water outlet 26.

[0043] In a further embodiment, the water outlet connector 6 has a first thread 61 that is threadedly connected to the water outlet hole 26, and a second thread 62 for connecting to an external pipe. The water outlet connector 6 is connected to an external water pipe through the second external thread 62 to achieve a shower water output effect, such as overhead spray or shower head output.

[0044] In addition, the groove of the valve core groove 23 is provided with a connecting thread 231, which facilitates the easy installation of a valve core handle for controlling the valve core on the valve core groove 23.

[0045] In a preferred embodiment, the hollow body 1 is a hollow square tube. The hollow body 1 has a first connecting hole 15 communicating with the first water passage cavity 13 and a second connecting hole 16 communicating with the second water passage cavity 14, as well as a through hole 17 for water outlet. The mounting hole 12 and the through hole 17 are respectively formed on two mutually perpendicular sides of the square tube; the first connecting hole 15 and the second connecting hole 16 are formed on either of the other two sides of the square tube. Thus, the inlet, outlet, and control ends of the shower faucet can be flexibly adjusted in position to form various shapes of stainless steel shower faucet products, meeting the needs of different usage scenarios.

[0046] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made within the scope of the claims of the present invention shall fall within the scope of the claims of the present invention.
