Description

Technical Field

[0001] This utility model relates to the field of shower faucet technology, specifically to a valve core tube for a shower faucet and a valve body having the valve core tube. Background Technology

[0002] A shower faucet is a valve that controls the flow of water from the tap. It primarily regulates water temperature through a rotating mechanism and is a core control component in a bathroom system. Its core function relies on the precise control of water flow through its internal valve core structure. It is mainly used for mixing hot and cold water, adjusting water temperature, and switching water flow paths (such as overhead showers, handheld showers, and under-discharge faucets). Installation methods include wall-mounted and recessed types: wall-mounted faucets are easier to maintain and offer a variety of styles, while recessed faucets save space but require pre-installed piping.

[0003] Because the pipes in shower faucets are quite complex, most shower faucets on the market currently use a one-piece all-metal design. The valve body and piping system are integrally formed by metal casting (such as copper alloy), the internal flow channels are then machined, and finally the valve core and outer shell are assembled. However, if all-metal casting is used, the complex machining and electroplating processes result in high production costs, making it impossible to further reduce production costs in the production of shower faucets. Utility Model Content

[0004] The purpose of this utility model is to address the defects and deficiencies of the existing technology by providing a valve core tube for a shower faucet and a valve body having the valve core tube.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a valve core tube for a shower faucet, comprising a valve core body, wherein the valve core body is provided with a cold water inlet end and a hot water inlet end, and the valve core body is provided with a cold and hot water valve seat for installing the cold and hot water valve core, wherein the cold and hot water valve seat is respectively provided with a cold water inlet hole and a hot water inlet hole, wherein the valve core body is respectively provided with a cold water inlet channel for connecting the cold water inlet end and the cold water inlet hole, and a hot water inlet channel for connecting the hot water inlet end and the hot water inlet hole, wherein the valve core body is provided with a water outlet hole, and the cold and hot water valve seat is provided with a water outlet channel for connecting to the water outlet hole.

[0006] A further improvement is that the hot and cold water valve seat has a limiting opening for engaging with the limiting rod at the bottom of the hot and cold water valve core when the hot and cold water valve core is installed on the hot and cold water valve seat, so that the cold water hole and hot water hole of the hot and cold water valve core are connected to the cold water inlet hole and hot water inlet hole respectively, and restricting the rotation of the bottom of the hot and cold water valve core.

[0007] A further improvement is that: there is one water outlet hole and one water outlet channel.

[0008] A further improvement is that the valve core body, cold water inlet end, hot water inlet end, cold and hot water valve seat, cold water inlet hole, hot water inlet hole, cold water inlet channel, hot water inlet channel, outlet hole, and outlet channel are integrally formed.

[0009] A further improvement is that: at least two water outlet holes are provided, one water outlet channel is provided, a water distribution valve seat for installing the water distribution valve core is provided on the valve core body, a water distribution inlet hole is opened on the water distribution valve seat, the water distribution inlet hole is connected to the water outlet channel through the water distribution channel, at least two water distribution outlet holes are opened on the water distribution valve seat, the number of water outlet holes corresponds to the number of water distribution outlet holes, and each water outlet hole is connected to each water distribution outlet hole respectively.

[0010] A further improvement is that the water outlet is provided with three holes, and the water distribution valve seat has three water distribution outlet holes, with each water outlet hole connected to each water distribution outlet hole.

[0011] A shower faucet includes a valve body, a valve core tube, and an assembly housing. The valve core tube comprises any of the valve core tubes described above. The assembly housing has an assembly inner hole, through which the valve core is installed. The valve core and the assembly inner hole are clearance-fitted. The assembly housing has cold water connection ports and hot water connection ports at the cold water inlet and hot water inlet for connecting to external cold water and hot water pipes, respectively. After the valve core is installed on the assembly housing, a valve core cavity is formed at the end where the valve core is located. The assembly housing has a valve core gland at the valve core cavity for pressing the cold and hot water valve core onto the threaded surface of the cold and hot water valve seat when the valve core is installed in the valve core cavity. One end of the assembly housing is a closed end, and the other end is an open end formed through the assembly inner hole. The assembly housing has a water outlet corresponding to the position of the water outlet hole, and the water outlet, the cold water connection port, and the hot water connection port are connected to the assembly inner hole.

[0012] Further improvements include: at least two water outlet holes and one water outlet channel; a water distribution valve seat for installing the water distribution valve core on the valve core body; a water distribution inlet hole on the water distribution valve seat, which is connected to the water outlet channel via the water distribution channel; at least two water distribution outlet holes on the water distribution valve seat; at least two water outlet openings, with the number of water outlet openings corresponding to the number of water outlet holes and water distribution outlet holes; each water outlet hole being connected to each water distribution outlet hole and each water outlet opening; a water distribution valve core cavity located at the water distribution valve seat on the assembly housing; and a threaded surface on the assembly housing located at the water distribution valve core cavity, for pressing the water distribution valve core onto the water distribution valve seat when the water distribution valve core is installed in the water distribution valve seat.

[0013] A further improvement is that: the water outlet is provided with three holes, the water distribution valve seat is provided with three water distribution outlet holes, and the water outlet opening is provided with three holes, each water outlet hole being connected to each water distribution outlet hole respectively.

[0014] A further improvement is that one of the water outlets is a waterfall outlet, and a strip-shaped opening is provided on the assembly housing at the waterfall outlet. The strip-shaped opening is connected to the inner hole of the assembly. A waterfall outlet plate is detachably provided on the waterfall outlet, and a sealing ring is provided around the waterfall outlet plate. The waterfall outlet plate is engaged between the waterfall outlet and the strip-shaped opening.

[0015] Further benefits: After the valve core is installed into the assembly housing, the positions of the waterfall outlet and the strip opening correspond. At this time, the waterfall outlet plate is aligned with the position of the waterfall outlet and installed. The sealing ring is used to lock the waterfall outlet plate in the waterfall outlet, which can prevent the waterfall outlet plate from being detached from the waterfall outlet due to water pressure impact. After the waterfall outlet plate is installed, the valve core can be initially locked in the assembly housing to limit the rotation and movement of the valve core in the inner hole of the assembly.

[0016] A further improvement is that the assembly housing, assembly inner hole, cold water connection port, hot water connection port, and water outlet are all integrally formed.

[0017] A further improvement is that the assembly housing is an aluminum alloy housing, a zinc alloy housing, a stainless steel housing, or a PVD vacuum-coated plastic housing.

[0019] After adopting the above technical solution, the beneficial effects of this utility model are as follows: Compared with the traditional all-metal casting of shower faucets, this application produces the valve core tube and the assembly housing separately. During production, the valve core tube can be made of a lower-cost material (such as environmentally friendly plastic), while the assembly housing is made of a material with a metallic texture (such as stainless steel or PVD vacuum-coated plastic). After both are processed, the valve core body is pushed into the inner hole of the assembly housing from the open end at the other end, and the position of the valve core body is adjusted so that the cold water connection port and the hot water connection port correspond to the positions of the cold water inlet and the hot water inlet, respectively. At this time, the valve body of the shower faucet is formed. By selecting different materials for the valve core tube and the assembly housing, the production cost of the shower faucet can be further reduced.

[0020] Further benefits: During assembly and use, first install the hot and cold water valve cores into the hot and cold water valve seats. Adjust the cold water valve core to connect with the cold water inlet, hot water inlet, and outlet respectively. Then, screw the valve core cap into the threaded area. When the valve core cap presses the hot and cold water valve cores onto the hot and cold water valve seats, the hot and cold water valve cores press against the valve core body on the hot and cold water valve seats, thereby pushing the valve core body to press against the closed end of the assembly housing. The valve core cap is threaded onto the threaded surface to achieve a fixed state after assembly of the valve core body and the assembly housing. When disassembly is required, unscrew the valve core cap from the threaded area, remove the hot and cold water valve cores from the valve core cavity, and then remove the valve core body from the assembly housing. The detachable design makes it easy to repair or replace the valve core tube of the shower faucet. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figures 1 to 6 As shown, the technical solution adopted in this specific embodiment is: A shower faucet includes a valve body, a valve core tube, and an assembly housing. The valve core tube comprises a valve core body 1, which has a cold water inlet 2 and a hot water inlet 3. The valve core body 1 also has a cold and hot water valve seat 4 for mounting the cold and hot water valve cores. The cold and hot water valve seat 4 has a cold water inlet hole 5 and a hot water inlet hole 6, respectively. The valve core body 1 has a cold water inlet channel 7 connecting the cold water inlet 2 and the cold water inlet hole 5, and a hot water inlet channel 8 connecting the hot water inlet 3 and the hot water inlet hole 6, respectively. The valve core body 1 has a water outlet hole 9, and the cold and hot water valve seat 4 has a water outlet channel 10 communicating with the water outlet hole 9. The assembly housing 26 has an assembly inner hole 16, through which the valve core body 1 is mounted. The valve core body 1 and the assembly inner hole 16 are fitted with a clearance between them. The assembly housing 26 is provided with cold water connection ports 17 and hot water connection ports 18 at the cold water inlet 2 and hot water inlet 3, respectively, for connecting to external cold water and hot water pipes. After the valve core 1 is installed on the assembly housing 26, a valve core cavity 19 is formed at the end of the cold and hot water valve seat 4. A threaded surface 20 is provided on the assembly housing 26 at the valve core cavity 19 for pressing the cold and hot water valve core onto the cold and hot water valve seat 4 when the valve core is installed in the valve core cavity 19. One end of the assembly housing 26 is a closed end, and the other end is an open end formed through the assembly inner hole 16. An outlet opening 21 corresponding to the position of the outlet hole 9 is provided on the assembly housing 26, and the outlet opening 21, cold water connection port 17, and hot water connection port 18 are connected to the assembly inner hole 16. A cold and hot water valve core is disposed on the cold and hot water valve core seat within the valve core cavity 19. The length of the assembly housing 26 is greater than the overall length of the valve core 1. This greater length is equal to the height of the hot and cold water valve cores and the thickness of the limiting ring. After the assembly housing 26 is assembled with the valve core tube, the cold water connection port 17 and the hot water connection port 18 of the assembly housing 26 are connected to the external cold water and hot water pipelines through threaded posts and nuts (threaded unions or threaded connectors). After the threaded posts are inserted into the cold water connection port 17 and the hot water connection port, they can also be pressed against the surfaces of the cold water inlet end 2 and the hot water inlet end 3 of the valve core 1 to form a seal through compression; or the cold water connection port 17 and the hot water connection port 18 can be directly set as threaded unions or threaded connectors.

[0026] The hot and cold water valve seat 4 has a limiting opening 12 for engaging with the limiting rod at the bottom of the hot and cold water valve core when the hot and cold water valve core is installed on the hot and cold water valve seat 4, so that the cold water hole and hot water hole of the hot and cold water valve core are connected to the cold water inlet hole 5 and the hot water inlet hole 6 respectively, and restricting the rotation of the bottom of the hot and cold water valve core.

[0027] There is one water outlet hole 9 and one water outlet channel 10. When there is only one water outlet hole 9, the water outlet channel 10 is connected to the water outlet hole 9, so that the water from the hot and cold water valve core flows directly out of the water outlet hole 9.

[0028] The valve core body 1, cold water inlet 2, hot water inlet 3, hot and cold water valve seat 4, cold water inlet hole 5, hot water inlet hole 6, cold water inlet channel 7, hot water inlet channel 8, outlet hole 9, and outlet channel 10 are integrally formed. The limiting opening 12, water distribution valve seat 13, water distribution inlet hole 14, and water distribution outlet hole 15 are also integrally formed with the valve core body 1. The entire valve core tube is integrally injection molded from PVC, ABS, or PP plastic material.

[0029] At least two water outlet holes 9 are provided, and one water outlet channel 10 is provided. The valve core body 1 is provided with a water distribution valve seat 13 for installing the water distribution valve core. The water distribution valve seat 13 is provided with a water distribution inlet hole 14, which is connected to the water outlet channel 10 through a water distribution channel 27. The water distribution valve seat 13 is provided with at least two water distribution outlet holes 15, and at least two water outlet openings 21 are provided. The number of water outlet openings 21 corresponds to the number of water outlet holes 9 and water distribution outlet holes 15. Each water outlet hole 9 is connected to each water distribution outlet hole 15 and each water outlet opening 21. The assembly housing 26 is provided with a water distribution valve core cavity at the water distribution valve seat 13. The assembly housing 26 is provided with a threaded surface 20 at the water distribution valve core cavity for pressing the water distribution valve core onto the water distribution valve seat 13 when the water distribution valve core is installed in the water distribution valve core cavity. A limiting opening 12 can also be provided on the water distribution valve seat 13 for guiding and limiting the installation of the water distribution valve core. The number of water outlet holes 9 can be set to two, and the number of water distribution outlet holes 15 is also two. The two water outlet holes 9 are connected to the two water distribution outlet holes 15 respectively. At this time, the water distribution valve core is a water distribution valve core with a double water distribution structure. One of the two water outlet holes 9 can be connected to the top spray pipe for supplying water from the top spray shower, and the other can be connected to the hand spray shower, or one can be connected to the hand spray shower and the other can be connected to a water outlet head with a different water outlet mode.

[0030] The water outlet 9 is provided with three holes, and the water distribution valve seat 13 has three water distribution outlet holes 15. The water outlet opening 21 is provided with three separate holes, and each water outlet 9 is connected to each water distribution outlet hole 15. The positions of the water outlet 9 are as follows: Figure 1 As shown, it can also be set in other locations as needed or by choice.

[0031] One of the water outlets 9 is a waterfall outlet 22. A strip-shaped opening 23 is provided on the assembly housing 26 at the waterfall outlet 22, and the strip-shaped opening 23 communicates with the inner hole 16. A waterfall water outlet plate 24 is detachably mounted on the waterfall outlet 22, and a sealing ring 25 is provided around the waterfall water outlet plate 24. The waterfall water outlet plate 24 is snapped between the waterfall outlet 22 and the strip-shaped opening 23. The waterfall outlet 22 is a strip-shaped outlet. The waterfall water outlet plate 24 is a conical water outlet plate, and the waterfall water outlet plate 24 is tightly installed on the waterfall outlet 22 by the surrounding sealing ring 25.

[0032] like Figure 1 and Figure 2 As shown, for example, when there are three water outlets 9, the first water outlet 9 is installed on the top of the valve body and connected to the top spray pipe for supplying water to the top spray shower. The second water outlet 9 is located at the bottom of the valve body and connected to the hand spray pipe for supplying water to the hand spray shower. The third water outlet 9 is located at the bottom or front of the valve body (the end face away from the hot water end and the cold water end) and is set as the waterfall outlet 22 or other water outlet. Or, when the third water outlet 9 is located at the bottom, it is set as the outlet for a normal water column.

[0033] The assembly housing 26, assembly inner hole 16, cold water connection port 17, hot water connection port 18, and water outlet 21 are all integrally formed. The water distribution valve core cavity is connected to the assembly inner hole 16 and is integrally formed with the assembly housing 26. The overall structure of the assembly housing 26 is produced by integral injection molding, and the threaded surface 20 is processed by processing equipment after injection molding; or, a non-integral molding method can be selected, and the assembly housing 26 is processed by processing equipment to process the assembly inner hole 16, cold water connection port 17, hot water connection port 18, and threaded surface 20.

[0034] The assembly housing 26 is an aluminum alloy housing, a zinc alloy housing, a stainless steel housing, or a PVD vacuum-coated plastic housing.

[0035] The working principle of this utility model is as follows: Compared with the traditional all-metal casting of shower faucets, this application produces the valve core tube and the assembly housing 26 separately. During production, the valve core tube can be made of a lower-cost material (such as environmentally friendly plastic), while the assembly housing 26 is made of a material with a metallic texture (such as stainless steel or PVD vacuum-coated plastic). After both are processed, the valve core 1 is pushed into the assembly inner hole 16 from the open end of the other end of the assembly housing 26, and the position of the valve core 1 is adjusted so that the cold water connection port 17 and the hot water connection port 18 correspond to the positions of the cold water inlet 2 and the hot water inlet 3, respectively. At this time, the valve body of the shower faucet is formed. By selecting different materials for the valve core tube and the assembly housing 26, the production cost of the shower faucet can be further reduced. During assembly and use, first install the hot and cold water valve cores into the hot and cold water valve seats 4, and adjust the cold water valve core to connect with the cold water inlet 5, hot water inlet 6, and outlet 9 respectively. Then, screw the valve core cover into the threaded surface 20 so that the valve core cover presses the hot and cold water valve cores onto the hot and cold water valve seats 4. When the valve core cover presses the hot and cold water valve cores onto the hot and cold water valve seats 4 of the valve core body 1, the hot and cold water valve cores press against the hot and cold water valve seats 4, thereby pushing the valve core body 1 to press against the closed end of the assembly housing 26. The valve core cover is threaded onto the threaded surface 20 to achieve a fixed state after assembly of the valve core body 1 and the assembly housing 26. When disassembly is required, unscrew the valve core cover from the threaded surface 20, remove the hot and cold water valve cores from the valve core cavity 19, and then remove the valve core body 1 from the assembly housing 26. The detachable design makes it easy to repair or replace the valve core tube of the shower faucet. After the valve core 1 is installed into the assembly housing 26, the positions of the waterfall outlet 22 and the strip opening 23 correspond. At this time, the waterfall outlet plate 24 is aligned with the position of the waterfall outlet 22 and installed. The waterfall outlet plate 24 is then secured in the waterfall outlet 22 by the sealing ring 25. This prevents the waterfall outlet plate 24 from being dislodged from the waterfall outlet 22 due to water pressure. After the waterfall outlet plate 24 is installed, the valve core 1 can be initially secured in the assembly housing 26 to limit the rotation and movement of the valve core 1 in the assembly inner hole 16.
