Description

Technical Field

[0001] The invention relates to a basin faucet, in particular to a constant temperature basin faucet. Background Art

[0002] A basin faucet is a faucet installed on a bathroom sink. Existing basin faucets generally offer both warm and hot water. Most use a standard mixing valve cartridge, which dispenses warm or hot water for winter convenience. Some also utilize a thermostatic valve cartridge, which achieves both. Unlike standard basin faucets (i.e., those equipped with standard mixing valve cartridges), these types of faucets require no repeated adjustments to achieve the desired water temperature. Therefore, these thermostatically controlled faucets are more convenient and water-efficient. However, basin faucets with thermostatic valve cores also have the following drawbacks: These basin faucets are typically equipped with a thermostatic valve core and an on / off valve core, one for controlling water temperature and the other for turning the water on and off. This results in the faucet often having two prominent operating switches on its exterior: one for opening the water and the other for adjusting the water temperature. These switches are each comprised of an operating handwheel or handle. Some of these switches are located on opposite sides of the faucet body, while others are located on the top and the side of the faucet body. This results in the faucet having an additional, rather obtrusive, thermostatic switch compared to conventional basin faucets, significantly different in appearance and inconsistent with user habits of traditional basin faucets, causing many users to be uncomfortable. Furthermore, compared to conventional basin faucets, the addition of an obtrusive thermostatic switch (such as a thermostatic handwheel or handle) makes the overall structure of these basin faucets less compact and larger, thus increasing the space they occupy.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. Since a thermostatic component rotatable about the axis of the faucet body is provided on the side wall of the faucet body, and the thermostatic component is connected to the valve stem of the thermostatic valve core for temperature adjustment, the present invention can use the thermostatic component to adjust the temperature without providing an obtrusive thermostatic handwheel or handle, so that the overall appearance of the present invention can be not much different from that of an ordinary basin faucet, thereby not changing the user's usage habits, and also keeping the overall structure compact and small in size, reducing the space occupied.

[0020] 2. The thermostat is annular and is coaxially arranged with the faucet body, which can make the overall appearance of the present invention more simple, compact and beautiful, and also make the thermostat easy to install.

[0021] 3. The thermostat is connected to the valve stem of the thermostatic valve core via a gear transmission structure, making the connection structure between the thermostat and the valve stem simpler and more convenient, and the transmission is more reliable. The gear transmission structure preferably includes the transmission gear and an arc-shaped rack, which is simple in structure and easy to assemble.

[0022] 4. The valve core assembly forms a water flow channel that is separated from the faucet body. This prevents the heat of hot water in the valve core assembly from being directly transferred to the faucet body and scalding the user.

[0023] 5. The arrangement of the water outlet pipe enables the present invention to utilize the water outlet pipe to guide the water output by the valve core assembly to the water outlet of the faucet body, thereby preventing the heat of the hot water from being directly transferred to the faucet body when the valve core assembly discharges hot water, causing the water outlet part of the faucet body to become hot and accidentally scald the user.

[0024] 6. The valve core assembly and the water outlet pipe are made of lead-free materials, so that the present invention can avoid polluting water quality, thereby preventing the lead content in water from exceeding the standard and affecting human health and polluting the environment.

[0025] 7. The faucet body preferably includes the upper shell and the lower shell, and the temperature regulating component is located between the upper shell and the lower shell, so that the setting of the temperature regulating component is simpler and more convenient.

[0026] 8. The thermostat is equipped with a positioning structure on the upper or lower shell to indicate when a safe temperature has been reached, allowing the user to quickly adjust the thermostat to the position corresponding to the safe temperature, thereby enhancing user convenience. A first tactile gasket is fitted between the upper end of the thermostat and the upper shell, and a second tactile gasket is fitted between the lower end of the thermostat and the lower shell.

The thermostat 9 is connected to the valve stem 151 of the thermostatic valve core 15 for temperature adjustment. The axis of the faucet body refers to the axis of the portion of the faucet body used to install the valve core assembly. In this embodiment, the axis of the faucet body is approximately located in the vertical direction.

[0037] In this embodiment, the thermostat 9 is specifically annular and is coaxially arranged with the faucet body. In other embodiments, the thermostat is arc-shaped, etc. The thermostat 9 is approximately located in the middle of the faucet body.

[0038] In this embodiment, the thermostatic valve core 15 is located below the on / off valve core 4, and the axis of the thermostatic valve core 15 is parallel to the axis of the on / off valve core 4. The axis of the thermostatic valve core 15 and the axis of the on / off valve core 4 are respectively coincident with or parallel to the axis of the faucet body. In other embodiments, the axis of the thermostatic valve core coincides with the axis of the on / off valve core.

[0039] In this embodiment, the thermostat 9 is connected to the valve stem of the thermostatic valve core 15 through a transmission structure, and the transmission structure is specifically a gear transmission structure, which includes a transmission gear and an arc-shaped rack 901 provided on the inner side of the thermostat 9.

[0040] In this embodiment, the valve core assembly forms a water flow channel that is separated from the faucet body. Specifically, the valve core assembly also includes a switch valve body 6, a thermostatic valve body 10, and an adapter 8. The thermostatic valve body 10 is located below the switch valve body 6. The switch valve core 4 is installed in the switch valve body 6. The thermostatic valve core 15 is installed in the thermostatic valve body 10. The thermostatic valve body 10 and the switch valve body 6 are connected via the adapter 8 to form the water flow channel. Specifically, the switch valve core 4 is limited by a gland 3 that is threadedly connected to the top of the switch valve body 6. The gland 3 is externally threaded and connected to a semicircular cover 2. The thermostatic valve core 15 is limited in position in the thermostatic valve body 10 by a thermostatic copper gland 17 and a limiting ring 16. The present invention also includes a water outlet pipe 22, which is disposed within the faucet body. One end of the water outlet pipe 22 connects to the outlet end of the valve core assembly (i.e., the outlet end of the switch valve body 6), and the other end of the water outlet pipe 22 is located at the water outlet 703 provided on the faucet body. The valve core assembly and water outlet pipe 22 are made of lead-free materials. Specifically, the switch valve body 6, thermostatic valve body 10, adapter 8, and water outlet pipe 22 are made of plastic, which is lead-free and poorly conductive to heat. The faucet body is entirely or partially made of metal, providing a high-quality feel and an attractive appearance. Lead-free materials refer to materials that do not contain lead or have a lead content or leaching amount below a specified value.

[0041] In this embodiment, the faucet body specifically comprises an upper shell and a lower shell 14 disposed vertically. The on / off valve core 4 is located within the upper shell, and the thermostatic valve core 15 is located within the lower shell 14. Since the on / off valve core 4 is mounted within the on / off valve body 6, and the thermostatic valve core 15 is mounted within the thermostatic valve body 10, the on / off valve body 6 and the water outlet pipe 22 are also located within the upper shell, while the thermostatic valve body 10 is also located within the lower shell 14. The upper shell is provided with the water outlet 703. Specifically, the upper shell forms a first chamber 701 extending vertically through the upper shell, and the lower shell 14 forms a second chamber 141 extending vertically through the lower shell. The on / off valve body 6 is mounted within the first chamber 701, and the thermostatic valve body 10 is mounted within the second chamber 141. The thermostat 9 is located between the upper and lower shells 14. A first tactile gasket 27 is fitted between the upper end of the thermostat 9 and the upper shell, and a second tactile gasket 28 is fitted between the lower end of the thermostat 9 and the lower shell 14. Specifically, an annular upper step groove is provided at the upper end of the temperature regulating component 9, and the first tactile gasket 27 is sleeved on the upper step groove 905 and corresponds to the bottom end of the upper shell; an annular lower step groove 906 is provided at the lower end of the temperature regulating component 9, and the second tactile gasket 28 is sleeved on the lower step groove and corresponds to the top end of the lower shell 14.

[0042] In this embodiment, the thermostat 9 and the upper or lower shell 14 cooperate with a positioning structure for indicating that a safe temperature has been reached. The positioning structure includes a positioning groove 702 and a positioning head assembly 20 that corresponds to the positioning groove 702 and is elastically retractable. The positioning groove 702 is provided in one of the thermostat 9 and the upper or lower shell 14, and the positioning head assembly 20 is provided in the other of the thermostat 9 and the upper or lower shell 14. Specifically, the positioning groove 702 is provided in the upper shell, and the positioning head assembly 20 includes a positioning head 201 and a spring 202. The positioning head assembly 20 is provided in the thermostat 9. Specifically, the positioning head assembly 20 is provided in a receiving groove 904 provided at the upper end of the protrusion 902 of the thermostat 9: the spring 202 is located in the receiving groove 904, the positioning head 201 is fitted at the notch of the receiving groove 904, and the two ends of the spring 202 respectively abut against the positioning head 201 and the bottom of the receiving groove 904. When the positioning head 201 rotates with the thermostat 9 away from the positioning groove 702, the positioning head 201 is squeezed by the bottom of the upper shell into the accommodating groove 904, compressing the spring 202. When the positioning head 201 rotates with the thermostat 9 to the position corresponding to the positioning groove 702, the positioning head 201 is lifted by the spring 202 and snaps into the positioning groove 702, achieving positioning. At this point, it indicates that the thermostat 9 has been rotated to the position corresponding to the safe temperature. The safe temperature is a water temperature that will not burn the user and is comfortable for use, specifically 38-42°C, preferably 40°C, which is more comfortable for the user.

[0043] In this embodiment, the upper shell specifically includes a water outlet shell 7 and a decorative panel 24. The water outlet shell 7 is formed with the first chamber 701, the positioning groove 702 and the water outlet 703. The decorative panel 24 is covered on the water outlet shell 7 and is provided with a tolerance hole 241 for avoiding the top of the switch valve body 6 and / or the top of the switch valve core 4. The water outlet shell 7 is provided with an inner lining plate 23 for fixed connection with the decorative panel 24. The water outlet pipe 22 is located between the inner lining plate 23 and the water outlet shell 7. The other end of the water outlet pipe 22 is provided with a water outlet net nozzle 21 located at the water outlet 703. The water outlet net nozzle is also made of lead-free material. The water outlet shell 7 and the lower shell 14 are both made of metal, and the decorative panel 24 is made of tempered glass, making the overall appearance more elegant and exquisite. The thermostat 9 is located between the water outlet shell 7 and the lower shell 14, and the first tactile gasket 27 is matched with the thermostat 9 and the water outlet shell 7. The specific structure of the upper shell is not limited thereto. In other embodiments, the upper shell is an integrated metal part.

[0044] In this embodiment, the operating switch is an operating handle 1, one end of which is fixedly connected to the valve stem 401 of the switch valve core 4. Specifically, the operating handle 1 is fixed to the valve stem 401 of the switch valve core 4 using a hexagon socket flat head screw 26. A large three-claw electroplated buckle 25 is also secured to the front side of one end of the operating handle 1. The operating handle 1 is provided with an elongated hole 101 extending toward its other end. This not only serves a decorative purpose and reduces the material used for the handle, but also makes the operating handle 1 more convenient to operate. When the other end of the handle is lifted upward, the switch valve core 4 is opened, allowing water to flow through the water outlet nozzle 21. When the other end of the operating handle 1 is pressed downward, the switch valve core 4 is closed, and the water outlet nozzle 21 stops discharging water. In other embodiments, the operating switch is an operating handwheel, which is fixedly mounted on the valve stem of the switch valve core. Rotating the operating handwheel controls the opening and closing of the switch valve core.

[0045] In this embodiment, the inner lining plate 23 is fixedly connected to the water outlet housing 7 by screws 231, and 3M double-sided tape is provided on the upper surface of the inner lining plate 23 to fix the decorative panel 24. At the same time, the decorative panel 24 is pressed by the bottom end of the semicircular cover 2. The water outlet pipe 22 is fixedly connected to the water outlet housing 7 by screws 221, and the switch valve body 6 and the thermostatic valve body 10 are fixedly connected by a plurality of hexagonal flat-end screws 5 in combination with hexagonal nuts 11. The bottom end of the thermostatic valve body 10 is supported by the valve core seat 13, and a sealing rubber gasket 12 is provided between the two and locked with a plurality of screws 131; the valve core seat 13 is used to connect the hot water inlet pipe and the cold water inlet pipe, and the valve core seat 13 is fixedly connected to the lower shell 14 by a plurality of screws 132. The present invention also includes a plurality of sealing rings for sealing the parts that need to be sealed between the above components.

[0046] The thermostatic basin faucet of the present invention has a thermostatic component 9, which allows the present invention to adjust the temperature without the need for an obtrusive thermostatic handwheel or handle. Therefore, the overall appearance of the present invention can be basically the same as that of an ordinary basin faucet, which will not change the user's usage habits and also keep the overall structure of the present invention compact and small in size, reducing the space occupied. The thermostatic component 9 is connected to the valve stem of the thermostatic valve core 15 through a gear transmission structure, making the connection structure between the thermostatic component 9 and the valve stem of the thermostatic valve core 15 simpler, more convenient, and the transmission is reliable. The water flow channel of the valve core assembly is separated from the faucet body, and the water outlet pipe 22 is provided, so that the present invention also has an anti-scalding function, which prevents the heat of the internal hot water from being directly and quickly transferred to the faucet body and scalding the user. The valve core assembly, water outlet pipe 22 and other components are made of lead-free material to avoid polluting the water quality, thereby preventing the lead content in the water from exceeding the standard and affecting human health and polluting the environment. The temperature regulating element 9 and the upper shell or the lower shell 14 are matched with the positioning structure, which makes it convenient for the user to quickly adjust the temperature regulating element 9 to a position corresponding to a safe temperature, thereby making it more convenient for the user to use.
