Description

Technical Field

[0001] The invention relates to the technical field of water mixing valves, in particular to a water heater valve for bathrooms. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. For example: the hot and cold water valves used in water heaters to control the water flow rate and water temperature. Most water heater valves are directly hung at the bottom of the water heater, and the temperature and speed of the discharged water source are directly controlled through the water valve.

[0003] Existing bathroom water heater valves are also called mixing valves, which are mostly directly installed on the water supply pipes of the water heaters. When people take a bath, they need to open the valve and adjust the water flow and temperature to an appropriate level before taking a bath. After the temperature adjustment of the water heater valve is completed, the switch of the water heater valve is in a position that is extremely easy for users to touch, and it is easy to accidentally touch it when people use it, causing the temperature of the water discharged from the water heater valve to vary greatly. When the temperature is too high, it is easy to cause burns. When the temperature is too low, it affects the comfort of use and the stability of the operation. For this reason, we propose a bathroom water heater valve. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1-Figure 5 The water heater valve for bathroom shown in the figure includes a housing 1, a handle 2, a water mixing device 8, a water testing device 9 and an anti-touch device 10. A hot water pipe 3 and a cold water pipe 4 are arranged in the housing 1. A device pipe 5 is fixedly connected to the housing 1. A device cavity 6 connected to the device pipe 5 is opened in the housing 1. A water outlet pipe 7 connected to the device pipe 5 is fixedly connected to the device pipe 5. Two installation pipes 45 connected to the hot water pipe 3 and the cold water pipe 4 are fixedly connected to the housing 1. The water mixing device 8 is installed on the handle 2 for operating the water heater. When the handle 2 is used, the amount of water and the degree of mixing of hot and cold water are adjusted, and the hot and cold water are discharged after being evenly mixed. The water testing device 9 is installed on the device pipe 5, which is used to flow out separately when the amount of water is small and to adjust the hot and cold water to reach the temperature required by people. The anti-touch device 10 is installed on the device pipe 5, which is used to increase the water amount after the water testing device 9 reaches the appropriate water temperature so that the water is discharged through the water outlet pipe 7, and the water mixing device 8 is limited, so that the handle 2 at this time can only be turned on and off, and cannot be rotated to adjust the water temperature.

[0030] See also Figure 5-Figure 9The water mixing device 8 shown in the figure includes a sliding tube 11 slidably connected to the inner wall of the device cavity 6 and the device tube 5, and two groups of symmetrically distributed first opening and closing grooves 12 are provided on the side of one end of the sliding tube 11. A push-pull block 13 is fixedly connected to one end of the sliding tube 11 away from the first opening and closing groove 12, and a pull rod 14 is coaxially fixedly connected to one side of the push-pull block 13. An arc block 15 is fixedly connected to one end of the pull rod 14. A limiting groove 16 slidably connected to both the pull rod 14 and the arc block 15 is provided on the handle 2. A baffle 17 is fixedly connected to one end of the device tube 5, and the pull rod 14 passes through both sides of the baffle 17 and is slidably connected to the baffle 17. A mixing piece 18 for mixing hot and cold water in the device cavity 6 is provided in the device cavity 6.

[0031] See also Figure 5-Figure 6 The mixing element 18 shown in the figure includes a cover body 19, a threaded tube 20 is fixedly connected to the shell body 1, a threaded groove 21 threadedly connected to the threaded tube 20 is opened on the cover body 19, two symmetrically distributed rotating shafts 22 are rotatably connected to one side of the shell body 1, and a plurality of arc-shaped fan blades 23 are fixedly connected to the sides of the two rotating shafts 22, and a filter screen 44 rotatably connected to the inner wall of the sliding tube 11 is slidably connected.

[0032] The hot water in the water heater is then filtered through the filter screen 44 and then discharged to the other end of the sliding tube 11. When the water volume is small, the water in the sliding tube 11 will be discharged through the water testing device 9, which is convenient for people to quickly feel the water temperature. At this time, the hot water will not flow into the shower head from the water outlet pipe 7 for discharge, thus preventing the inappropriate water from flowing out and causing discomfort to people. The arc block 15 is driven to rotate, thereby driving the pulling rod 14 to rotate and driving the sliding tube 11 to rotate, changing the size of the connecting openings of the two first opening and closing grooves 12 and the cold water pipe 4 and the hot water pipe 3. When the handle 2 is turned to the hot water pipe 3 side, the connecting opening of the hot water pipe 3 and the first opening and closing groove 12 is increased, and the opening of the cold water pipe 4 is reduced. At this time, the water temperature is hotter, while the water temperature is lower when it is turned to the cold water side. When the water temperature is adjusted to a suitable temperature, the handle 2 is continued to be tilted, and the pulling rod 14 is pulled to move the sliding tube 11 outward, and the water flow increases. At this time, the water in the sliding tube 11 is no longer discharged through the water testing device 9, but is discharged through the water outlet pipe 7 to the shower head, and bathing can be carried out. At this time, the anti-touch device 10 will be linked to limit the pulling rod 14, making it difficult for the pulling rod 14 to rotate. The handle 2 can only be turned on and off, and cannot be rotated to adjust the water temperature, thereby effectively preventing people from accidentally touching the handle 2 during the shower process, causing the handle 2 to rotate and causing the water temperature to change too much, causing discomfort to the human body.

[0033] It is worth noting that: by rotating the cover body 19, the threaded groove 21 and the threaded tube 20 can be disconnected, and the cover body 19 can be driven to take out the rotating shaft 22 and the filter screen 44 from the device cavity 6. At this time, the stains remaining on the arc-shaped fan blades 23 and the filter screen 44 can be easily cleaned to prevent the stains from remaining in the device cavity 6 for a long time and affecting the water quality.

[0034] Example 2

[0035] See also Figure 5 and Figure 8-Figure 10Embodiment 2 is described. This embodiment further describes Embodiment 1. The water testing device 9 shown in the figure includes a water testing tube 24 fixedly mounted on the bottom surface of the device tube 5. A first fan-shaped groove 25 is provided on the side of the sliding tube 11 close to the water testing tube 24. A second fan-shaped groove 26 is provided on the side of the sliding tube 11 close to the water outlet pipe 7. The first fan-shaped groove 25 is connected to the sliding tube 11 and the water testing tube 24. The second fan-shaped groove 26 is connected to the sliding tube 11 and the water outlet pipe 7. A control member 27 is provided in the water testing tube 24 for allowing the user to adjust the water temperature by turning the handle 2 when the first fan-shaped groove 25 is connected to the water testing tube 24.

[0036] See also Figure 7-Figure 9 The control member 27 shown in the figure includes a fixed ring 28 fixedly installed in the water test tube 24, the top of the fixed ring 28 is fixedly connected to a first spring 29, the first spring 29 is fixedly connected to a lifting tube 30 slidably connected to the inner wall of the water test tube 24, and the top of the lifting tube 30 is slidably connected to the edge of the first fan-shaped groove 25.

[0037] In the present embodiment, when the handle 2 is tilted to pull the pull rod 14 so that the sliding tube 11 moves outward, the first fan-shaped groove 25 will first be connected with the water testing tube 24, and the water in the sliding tube 11 will flow into the lifting tube 30 through the first fan-shaped groove 25 and be discharged downward through the water testing tube 24. At this time, people only need to place their hands on the water outlet of the water testing tube 24 to feel the temperature of the water flow. At this time, the water flow is small, and people will not get scalded or feel too cold and uncomfortable when feeling the water temperature. At the same time, the water flow is small at this time, and it will be difficult to transport it upward directly into the shower head due to the low water pressure. Compared with the traditional water mixing valve, the design of this water testing structure effectively avoids the need for people to remove the shower head when testing the water temperature or accidentally touch the switch, so that water flows directly from the shower head to spray. When people's clothes get wet, when the first fan-shaped groove 25 slides above the lifting tube 30, the first spring 29 will push the lifting tube 30 to move up and slightly get stuck in the first fan-shaped groove 25, causing slight vibration and limit. At this time, people can know that they are in the water testing stage, so they can turn the handle 2 to adjust the water temperature. When the water temperature is adjusted to a suitable level, the handle 2 is directly lifted and no longer turned. At this time, the pulling rod 14 directly pulls the sliding tube 11 outward, and the water flow increases while the lifting tube 30 is disconnected from the first fan-shaped groove 25, and the second fan-shaped groove 26 is connected to the water outlet pipe 7. The water in the sliding tube 11 flows into the water outlet pipe 7 through the second fan-shaped groove 26, and then flows into the shower head connected to the water outlet pipe 7 for discharge, and then you can take a shower.

[0038] Example 3

[0039] See also Figure 8-Figure 10Embodiment 3 is described. This embodiment further describes embodiment 1. The anti-touch device 10 shown in the figure includes a fixed plate 31 fixedly installed in the device tube 5. The side of the fixed plate 31 is fixedly connected with an inflatable bag 32. The side of the inflatable bag 32 away from the fixed plate 31 is fixedly connected to the side of the sliding tube 11. The pulling rod 14 passes through both sides of the fixed plate 31 and is slidably connected to the fixed plate 31. A fixed block 33 fixedly connected to the baffle 17 is fixedly connected to the fixed plate 31. A connecting hole 34 connected to the inflatable bag 32 is opened on the fixed plate 31. An inflatable cavity 35 connected to the connecting hole 34 is provided between the fixed plate 31 and the baffle 17. A limiting member 36 is provided on the fixed block 33 for limiting the pulling rod 14 after the inflatable bag 32 fills gas into the inflatable cavity 35.

[0040] See also Figure 8-Figure 10 The limiting member 36 shown in the figure includes a plurality of snap-in blocks 37, a plurality of sliding grooves 38 are provided on the fixed block 33, which are respectively slidably connected to the plurality of snap-in blocks 37, a rubber pad 39 is fixedly connected to one end of the snap-in block 37, a plurality of guide grooves 40 connected to the sliding grooves 38 are provided in the fixed block 33, a second spring 41 is fixedly connected in the guide groove 40, a guide block 42 slidably connected to the guide groove 40 is fixedly connected to the second spring 41, the guide block 42 is fixedly connected to the side of the sliding block, and an anti-slip groove 43 is provided on the side of the pull rod 14.

[0041] In this embodiment, after adjusting the water temperature, the handle 2 is lifted so that the pull rod 14 moves the sliding tube 11 outward, and the sliding tube 11 pushes the inflatable bag 32, and the fluid in the inflatable bag 32 is discharged into the inflation chamber 35 through the connecting hole 34. The air pressure in the inflation chamber 35 increases, thereby pushing one end of the clamping block 37 so that the clamping block 37 slides to one side of the pull rod 14. The clamping block 37 drives the guide block 42 to slide in the guide groove 40 to compress the second spring 41. The clamping block 37 continuously pushes the rubber pad 39 to slide in the sliding groove 38 until it conflicts with the pull rod 14. At this time, the pull rod 14 slides out just enough to make the position of the anti-skid groove 43 conflict with the rubber pad 39, thereby making the anti-skid effect better. Since the anti-skid groove 43 is opened in the same direction as the pull rod 14, the pull rod 14 can slide at this time, but it is difficult to rotate, so that the handle 2 is When the force is small, it is difficult to rotate to change the water temperature. At this time, if people accidentally touch the handle 2, the safety factor will be increased. Only the size of the water flow can be changed. The change in the size of the water flow has a small impact on the body and will not cause scalding or overcooling. When people have finished using it, they can press down the handle 2 to push the pull rod 14 to slide inward, thereby causing the sliding tube 11 to slide, and the first opening and closing groove 12 is no longer connected to the cold water pipe 4 and the hot water pipe 3, thereby closing the water outlet. At this time, the sliding tube 11 will drive one side of the inflatable bag 32 to move, and the internal space of the inflatable bag 32 will increase, and the fluid in the inflatable chamber 35 will be drawn into the inflatable bag 32 through the connecting hole 34. The pressure in the inflatable chamber 35 is reduced, and the thrust on the clamping block 37 is reduced. The second spring 41 rebounds and drives the guide block 42 and the clamping block 37 away from the pulling rod 14, releasing the limit on the pulling rod 14, so that the device can be reset.
