Description

Technical Field

[0001] This utility model relates to the field of bathroom water flow pipeline technology, and in particular to a bathroom water flow pipeline temperature control interruption structure and a shower head having the same structure. Background Technology

[0002] A shower head, also known as a shower spray head, is a shower device that disperses water flow through a spray nozzle. Originally used for watering plants, it was later improved into a common bathroom fixture. Its main functions include body cleaning and massage. Based on shape, it can be divided into three types: handheld, overhead, and stationary. Installation must be adapted to the user's height and water pressure conditions. Early shower heads were mainly made of plastic, but later, upgraded products with silicone nozzles and integrated sound functions were developed. Water flow patterns have expanded from a single water flow to various types such as standard, massage, and turbine sprays.

[0003] However, existing showerheads typically use simple manual valves to open and close the water flow. Users only manually close the valve when they feel the water temperature is too high, failing to automatically control the flow based on water temperature. This poses a significant risk of scalding users, especially infants, if the water temperature becomes unexpectedly high. Infants require bath water at 38-40℃. If the water temperature suddenly rises during bathing and parents fail to notice and manually shut off the flow in time, the infant's skin could be easily burned. The showerheads lack automatic and timely flow control when the water temperature is too high, resulting in an unsafe design, poor reliability, and inconvenience. Utility Model Content

[0004] The purpose of this utility model is to provide a temperature-controlled flow interruption structure for bathroom water pipes and a shower head with the same structure, aiming to solve the technical problem that bathroom water valves in the prior art are not safe and reliable enough.

[0005] To achieve the above objectives, the present invention provides a temperature-controlled flow interruption structure for bathroom water pipes, comprising:

[0006] The pipe body has an inlet at its first end and an outlet at its second end. An overflow hole is provided on the inner wall of the pipe body so that the inlet can be connected to the inner cavity of the pipe body through the overflow hole.

[0007] A temperature-sensing deformation device is disposed in the inner cavity of the tube body;

[0008] A valve plug, one end of which is connected to the temperature sensing deformation device, and the other end of which is correspondingly positioned to the water inlet;

[0009] An elastic element, one end of which abuts against the valve plug, and the elastic element is used to apply a force to the valve plug in a direction away from the inlet.

[0010] Specifically, when the temperature-sensing deformation device encounters water with a temperature greater than a preset temperature, it can extend and push the valve plug to move, thereby blocking the water inlet; when the temperature-sensing deformation device encounters water with a temperature less than or equal to a preset temperature, it can contract and, by means of the elastic element, push the valve plug to move in a direction away from the water inlet, thereby opening the water inlet.

[0011] In one possible implementation, the inner circumferential surface of the tube body extends inward to form an annular step, the outer circumferential surface of the valve plug extends inward to form a first convex ring, one end of the elastic member abuts against the first convex ring, and the other end of the elastic member abuts against the annular step.

[0012] And / or, the temperature-sensing deformation device is a temperature-sensing element or a memory spring.

[0013] In one possible implementation, the overflow hole is formed on the annular step;

[0014] And / or, the valve plug is provided with a plug portion at one end near the water inlet, and a first annular groove is formed on the outer circumferential surface of the plug portion, and a first sealing ring is embedded in the first annular groove.

[0015] In one possible implementation, the valve plug has a slot at one end away from the water inlet, and the temperature-sensing deformation device has a protrusion at one end, so that the valve plug can be connected to the temperature-sensing deformation device by inserting the protrusion into the slot.

[0016] In one possible implementation, the inner circumferential surface of the tube extends inward to form an annular body, with an assembly hole formed at the center of the annular body. The temperature-sensing deformation device is inserted into the assembly hole, and multiple through holes are spaced apart along the circumference of the annular body so that the inlet and the outlet can be connected through the through holes.

[0017] In one possible implementation, the tube body includes an outer tube and a first inner tube that are nested together, and the annular body is disposed in the first inner tube;

[0018] And / or, the inner circumferential surface of the assembly hole is provided with an internal thread, the outer circumferential surface of the temperature sensing deformation device is provided with an external thread, the temperature sensing deformation device is threadedly connected to the assembly hole, and the outer circumferential surface of the temperature sensing deformation device extends outward to form a second convex ring, so that the second convex ring abuts against the end face of the annular body away from the valve plug, thereby limiting the position.

[0019] In one possible implementation, the inlet is formed at the center of the annular step, the inlet extending in an expanding manner near one end of the valve plug, and the overflow hole is opened on the annular step extending parallel to the axial direction.

[0020] In addition, the technical solution of this utility model provides a temperature control and flow interruption structure for bathroom water flow pipes, including:

[0021] The pipe body has an inlet at its first end and an outlet at its second end.

[0022] A temperature-sensing deformation device is disposed inside the tube;

[0023] A valve plug, one end of which is connected to the temperature sensing deformation device, and the other end of which is correspondingly positioned to the water inlet;

[0024] Specifically, when the temperature-sensing deformation device senses that the water temperature is greater than or less than a preset temperature, it can extend or contract, and drive the valve plug to move in a direction closer to or away from the water inlet, thereby closing or opening the water inlet.

[0025] In one possible implementation, an elastic element is also included, one end of which abuts against the valve plug, and the elastic element is used to apply a force to the valve plug in a direction away from the inlet.

[0026] Alternatively, the inner circumferential surface of the pipe body extends inward to form an annular step, so that the water inlet is formed at the center of the annular step, and an overflow hole is provided on the annular step so that the water inlet is connected to the inner cavity of the pipe body through the overflow hole.

[0027] Alternatively, when the valve plug blocks the inlet, the water flow gathered at the inlet can flow into the inner cavity of the pipe body through the overflow gap left between the valve plug and the inlet.

[0028] In addition, the present invention provides a shower head with multiple shower spray holes at the head and a water inlet at the end of the handle. The handle is hollow inside. The shower head is characterized by including a bathroom water flow temperature control interruption structure as described in any of the above technical solutions, wherein the bathroom water flow temperature control interruption structure is installed inside the handle of the shower head.

[0029] As can be seen from the above technical solution, the bathroom water flow pipeline temperature control interruption structure and the shower head with it can extend or contract when the temperature sensing deformation device senses that the water temperature is greater than or less than the preset temperature, and drive the valve plug to move in the direction close to or away from the water inlet, thereby realizing the closing or opening of the water inlet. That is, when the water temperature is too high and exceeds the preset temperature, the temperature sensing deformation device can extend to automatically control the valve plug to close, avoiding the user's skin from being scalded by excessively high water temperature or causing the user to feel uncomfortable. Furthermore, by monitoring the water temperature in real time and reacting in a timely manner, the safety and reliability of the structural design are effectively improved. There is no need to manually close the valve, making it convenient to use.

[0045] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Please refer to the following: Figures 1 to 7This embodiment provides a temperature-controlled flow interruption structure for a bathroom water pipe, including a pipe body 100, a temperature-sensing deformation device 200, a valve plug 300, and an elastic element 400. The first end of the pipe body 100 has an inlet 132, and the second end has an outlet. An overflow hole 133 is provided on the inner wall of the pipe body 100, allowing the inlet 132 to communicate with the inner cavity of the pipe body 100 through the overflow hole 133. The temperature-sensing deformation device 200 is disposed within the inner cavity of the pipe body 100. One end of the valve plug 300 is connected to the temperature-sensing deformation device 200, and the other end of the valve plug 300 is correspondingly disposed with respect to the inlet 132. One end of the elastic element 400 abuts against the valve plug 300, and the elastic element 400 applies a force to the valve plug 300 in a direction away from the inlet 132. The force is applied when the temperature-sensing deformation device 200... When the temperature-sensing deformation device 200 encounters water with a temperature greater than the preset temperature, it can extend and push the valve plug 300 to move, thereby blocking the water inlet 132. When the water temperature is greater than the preset temperature, that is, the water temperature is too high, the water inlet 132 is automatically blocked in time, effectively preventing hot water from coming into contact with the user's skin, making it safer and more reliable. When the temperature-sensing deformation device 200 encounters water with a temperature less than or equal to the preset temperature, it can contract and push the valve plug 300 away from the water inlet 132 by means of the elastic element 400, thereby opening the water inlet 132. When the water temperature is less than or equal to the preset temperature, that is, the water temperature is suitable or warm, the water inlet 132 is automatically opened to allow water of suitable temperature to flow in for people to take a bath. The preset temperature is usually the water temperature range suitable for people to take a bath, in the range of 35-40℃.

[0047] As can be seen, the bathroom water flow pipeline temperature control interruption structure of this embodiment can extend or contract when the temperature sensing deformation device 200 senses that the water temperature is greater than or less than the preset temperature, and drive the valve plug 300 to move in the direction close to or away from the water inlet 132, thereby realizing the closure or opening of the water inlet 132. That is, when the water temperature is too high and exceeds the preset temperature, the temperature sensing deformation device 200 can extend to automatically control the valve plug 300 to close, avoiding the user's skin from being scalded by the water temperature or causing the user discomfort. Furthermore, by monitoring the water temperature in real time and reacting in a timely manner, the safety and reliability of the structural design are effectively improved. There is no need to manually close the valve, making it convenient to use.

[0048] It should be noted that the temperature-sensing deformation device 200 is a temperature-sensing element or a memory spring. The temperature-sensing element, also known as a temperature-sensitive element, is a functional component used to sense temperature changes and generate a driving action. Depending on the temperature-sensing medium inside, temperature-sensing elements can be divided into solid, liquid, and gaseous types. Solid temperature-sensing elements often use paraffin wax as the medium. In comparison, paraffin wax temperature-sensing elements have a shorter lifespan, typically not exceeding 5 years, while liquid and gaseous temperature-sensing elements can last for more than 20 years. Paraffin wax temperature-sensing elements are also far inferior to liquid and gaseous temperature-sensing elements in terms of sensing sensitivity and temperature control stability. Therefore, paraffin wax temperature-sensing elements are considered outdated technology in Europe, but due to their low price, they are still produced domestically and internationally. Liquid temperature-sensing elements have wide applicability and stable performance, and are far superior to paraffin wax temperature-sensing elements in terms of cost-effectiveness. Currently, they are the dominant product in the European and domestic markets. Furthermore, the memory spring is made of a memory metal alloy, with nickel-titanium alloy being a common material. It can expand and contract according to different water temperatures to achieve the aforementioned temperature-sensing deformation function.

[0049] In this embodiment, the inner circumferential surface of the pipe body 100 extends inward to form an annular step 131, and the outer circumferential surface of the valve plug 300 extends inward to form a first convex ring 330. One end of the elastic member 400 abuts against the first convex ring 330, and the other end of the elastic member 400 abuts against the annular step 131. The elastic member 400 is a compression spring, and the compression spring is sleeved on the valve plug 300. This arrangement is such that when the temperature sensing deformation device 200 encounters warm or cold water of a suitable temperature and contracts, the elastic force of the elastic member 400 pushes the valve plug 300 to move and open the water inlet 132, thereby improving the stability and reliability of the structural design.

[0050] In one possible implementation, the overflow hole 133 is formed on the annular step 131. When the temperature sensing deformation device 200 senses that the water temperature is too high, it extends and pushes the valve plug 300 to move, thereby blocking the inlet 132. At this time, the inlet 132 is cut off from the inner cavity of the pipe body 100. The temperature sensing deformation device 200 is set in the inner cavity of the pipe body 100. When the temperature of the water flow gathered at the inlet 132 drops to less than or equal to the preset temperature, a small amount of water flow gathered at the inlet 132 can flow into the inner cavity of the pipe body 100 through the overflow hole 133 with a smaller diameter. When the temperature sensing deformation device 200 senses that the water temperature has reached a suitable water temperature, it contracts, thereby reopening the inlet 132, allowing the water flow at a suitable temperature from the inlet 132 to flow out through the outlet for people to use for bathing. In addition, forming the overflow hole 133 on the annular step 131 results in a simple and reliable structure, lower manufacturing difficulty and production cost, and facilitates industrial implementation and mass production.

[0051] In another possible implementation, when the valve plug 300 blocks the inlet 132, an overflow gap is left between the valve plug 300 and the inlet 132, allowing a small amount of water collected in the inlet 132 to flow into the inner cavity of the pipe body 100 through the overflow gap. When the temperature sensing deformation device 200 comes into contact with the water and reaches a suitable temperature, it contracts, thereby reopening the inlet 132 and allowing water at a suitable temperature to flow out through the outlet for people to use for bathing. Here, replacing the overflow hole 133 with the overflow gap can also achieve the purpose of automatically reopening the inlet 132.

[0052] Specifically, a plug portion 310 is provided at one end of the valve plug 300 near the water inlet 132. A first annular groove is formed on the outer circumferential surface of the plug portion 310, and a first sealing ring 320 is embedded in the first annular groove. The end of the valve plug 300 near the water inlet 132 extends circumferentially to form the plug portion 310, and the sealing performance of the plug portion 310 when inserted into the water inlet 132 is improved by the first sealing ring 320, making the structure more stable and reliable.

[0053] An inlet 132 is formed at the center of the annular step 131. The end of the inlet 132 near the valve plug 300 extends in an expanding shape so that the plug portion 310 of the valve plug 300 can be smoothly inserted into the inlet 132. An overflow hole 133 extends parallel to the axial direction and is opened on the annular step 131.

[0054] Furthermore, a groove 340 is provided at the end of the valve plug 300 away from the water inlet 132, and a column-shaped protrusion 210 is provided at one end of the temperature sensing deformation device 200, so that the valve plug 300 and the temperature sensing deformation device 200 can be connected by inserting the protrusion 210 into the groove 340.

[0055] In one possible implementation, the inner circumferential surface of the pipe body 100 extends inward to form an annular body 121, with an assembly hole 122 formed at the center of the annular body 121. The temperature sensing deformation device 200 is detachably inserted into the assembly hole 122, and a plurality of through holes 123 are spaced apart along the circumference of the annular body 121 so that the inlet 132 and the outlet can be connected through the through holes 123. With this configuration, the temperature sensing deformation device 200 can be installed in the inner cavity of the pipe body 100, and the temperature sensing deformation device 200 is installed through the structure of the annular body 121. The structure is stable and compact, and the processing difficulty and production cost are low.

[0056] Specifically, the inner circumferential surface of the mounting hole 122 is provided with an internal thread, and the outer circumferential surface of the temperature sensing deformation device 200 is provided with an external thread 220. The temperature sensing deformation device 200 is threadedly connected to the mounting hole 122, and the outer circumferential surface of the temperature sensing deformation device 200 extends outward to form a second convex ring 230, so that the second convex ring 230 abuts against the end face of the end of the annular body 121 away from the valve plug 300 to limit it. This arrangement allows the temperature sensing deformation device 200 to be threadedly connected to the mounting hole 122 to achieve a detachable connection. Furthermore, the end of the temperature sensing deformation device 200 away from the valve plug 300 extends outward along the axial direction to form a shaft end 240. The temperature sensing deformation device 200 is screwed into or out of the mounting hole 122 through the shaft end 240 to facilitate disassembly, maintenance and replacement in the future.

[0057] Among them, the main part between the protrusion 210 and the threaded section of the temperature-sensing deformation device 200 is a telescopic part that can extend or contract in response to changes in water temperature. Of course, this telescopic part of the temperature-sensing deformation device 200 adopts existing technology, and the specific working principle and structure of the telescopic change will not be described in detail here.

[0058] In one possible implementation, the tube body 100 includes an outer tube 110 and a first inner tube 120 that are nested together. The annular body 121 is disposed in the first inner tube 120. Thus, the design structure of the inner and outer tubes 110 facilitates the smooth installation of the valve plug 300, the elastic element 400 and the temperature sensing deformation device 200 between the annular step 131 and the annular body 121. This makes industrial production assembly convenient, quick and efficient.

[0059] Specifically, the pipe body 100 also includes a second inner pipe 130, which is disposed in the first inner pipe 120. An annular step 131 is disposed at one end of the second inner pipe 130. The inner circumferential surface of the outer pipe 110 extends to form a limiting step 112. The two ends of the second inner pipe 130 abut against the limiting step 112 and the annular body 121, respectively. A second sealing ring 124 is provided between the outer pipe 110 and the first inner pipe 120. A ring cover 500 is provided at the end of the outer pipe 110 away from the water inlet 132. The ring cover 500 is connected to the outer pipe 110 by welding or threading to limit the first inner pipe 120. The end face of the ring cover 500 is provided with a plurality of water flow holes 510 spaced apart along the circumference. The water flow holes 510 are connected to the water outlet.

[0060] In addition, this embodiment provides a shower head with multiple shower spray holes evenly distributed on its head. A water inlet is located at the end of the shower head handle, allowing connection to the hot and cold water mixing valve of a water heater. The handle is hollow inside. The pipe body 100 of the bathroom water flow temperature control interruption structure is installed inside the shower head handle. The inlet 132 is closer to the shower head's water inlet than the outlet, so that when the shower water temperature is too high, the temperature sensing deformation device 200 drives the valve plug 300 to move. The water inlet 132 is automatically closed to prevent the water from the shower spray nozzles from being too hot and scalding the user's skin, thereby improving safety and reliability. One end of the outer tube 110 of the pipe body 100 is threaded to connect with the shower handle for installation. In addition, a third sealing ring 111 is provided between the outer tube 110 of the pipe body 100 and the inner wall of the shower handle. The other specific structures and principles of the shower are existing technologies and will not be described in detail here.

[0061] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0062] This utility model's bathroom water flow pipeline temperature control interruption structure can extend or contract when the temperature sensing deformation device 200 senses that the water temperature is greater than or less than the preset temperature, and drive the valve plug 300 to move in the direction close to or away from the water inlet 132, thereby closing or opening the water inlet 132. That is, when the water temperature is too high and exceeds the preset temperature, the temperature sensing deformation device 200 can extend to automatically control the valve plug 300 to close, avoiding the user's skin being scalded by excessively high water temperature or causing the user discomfort. Furthermore, by monitoring the water temperature in real time and reacting promptly, it effectively improves the safety and reliability of the structural design, eliminates the need for manual valve closure, and is convenient to use.
