Constant-temperature valve core

Abstract

The invention discloses a constant-temperature valve core, which comprises a valve core body, a first waterway director, a second waterway director and a regulating switch which are connected sequentially, wherein a plurality of heat-insulating sleeves are arranged outside the valve core body, the first waterway director and the second waterway director respectively; the first waterway director is matched with the second waterway director; the first waterway director and the second waterway director protrude oppositely and are connected to form a combined part with a communicated hollow cavity; hot-water channel is formed between the combined part and the heat-insulating sleeves, and is communicated with a hot-water inlet; a hollow water mixing channel is formed in the hollow cavity of the combined part; and a first filter is arranged in the hot-water channel, and a second filter is arranged in the water mixing channel. The constant-temperature valve core has the functions of scald prevention, deodorization, blocking prevention, sterilization, disinfection and environmental protection.

Description

technical field [0001] The invention relates to a valve core, in particular to a special thermostatic valve core for a thermostatic faucet which can keep the water temperature constant and stable. Background technique [0002] At present, the thermostatic valve cores of existing solar water heaters, electric water heaters, and boilers have a certain effect of maintaining water temperature, but they also have many shortcomings: [0003] 1. The main disadvantage is that the control of water temperature is not stable enough. For example, when the water pressure is unstable, the temperature changes, so that the outlet water temperature cannot reach the set temperature; or when the hot water temperature is unstable, the water temperature cannot reach the set temperature, resulting in intermittent cold and hot phenomena. When the user uses the water heater to bathe or the boiler to bathe, the water temperature cannot be kept stable, which brings inconvenience to the user. Moreov...

Problems solved by technology

[0003] 1. The main disadvantage is that the control of water temperature is not stable enough

For example, when the water pressure is unstable, the temperature changes, so that the outlet water temperature cannot reach the set temperature; or when the hot water temperature is unstable, the water temperature cannot reach the set temperature, resulting in the phenomenon of hot and cold

When the user uses the water heater to bathe or the boiler to bathe, the water temperature cannot be kept stable, which brings inconvenience to the user

Moreover, when the user uses the solar water heater to take a bath, one of the two water supply pipelines is a solar hot water channel, and the other is a tap water channel. When the tap water is cut off, the solar hot water channel cannot be stopped in time. Only hot water is released, which can easily cause serious consequences of scalding people

[0004] 2. Ordinary faucets have not been used for a long time or due to water quality reasons. When using ordinary thermostatic faucets, it is easy to emit peculiar smell while draining water.

[0005] 3. The size of the filter in the ordinary thermostatic faucet is small, and the filtering effect is poor. If the water quality is poor or the water contains sediment, scale and other factors, it is easy to cause the faucet to be blocked, and it is easy to reduce the service life of the thermostatic faucet. In severe cases, it will lead to constant temperature failure and other conditions.

[0006] 4. Ordinary constant temperature faucets are prone to breed bacteria due to long-term use or poor water quality. When used in bathing or other situations, it is easy to cause discomfort to the human body, and it is easy to cause skin diseases such as skin itching and rashes.

[0007] 5. When the ordinary thermostatic valve core and the faucet are joined together, the faucet shell needs to be formed through the sanding process, because the use of sanding and other processes is likely to bring certain pollution to the environment, so it is not conducive to environmental protection
