Description

Thermometer adhered to outer wall of fish tank

Technical Field

The utility model relates to a paste thermometer at fish bowl outer wall belongs to fish bowl thermometer technical field.

Background

The fish tank is a transparent tank body for feeding ornamental fish, and a glass tank is mostly adopted. The fish tank can be used for breeding fishes in a normal temperature state and can also be used for breeding tropical fishes and other tropical aquatic animals and plants. Tropical fish is fresh water fish living in tropical and subtropical environments near the equator of africa, america and asia, the water temperature suitable for the tropical fish to live is usually between 20 and 30 ℃, and the specific suitable temperature and the variety of the tropical fish have a certain relationship. Therefore, one of the conditions for rearing tropical fish is to monitor and control the temperature of the water in the aquarium.

In the high latitude areas which are relatively cold in winter, tropical fish are raised, and a thermometer for monitoring the water temperature and a heater for circularly heating the water body are required to be arranged in the fish tank. When the environment temperature is lower than the suitable temperature of the tropical fish, the thermometer can send out an alarm signal so as to start the heater to circularly heat the water body in the fish tank until the water temperature is raised to a suitable temperature range.

At present, there are non-contact thermometers and direct-contact thermometers for monitoring the temperature of fish tanks. Non-contact thermometers typically use infrared temperature sensors for sensing, which are relatively expensive and greatly affected by ambient temperature compared to contact thermometers. The contact thermometer is used for monitoring the temperature by contacting a probe of a temperature sensor with an object to be measured (a fish tank). Contact thermometer can directly paste on the fish bowl outer wall through the double faced adhesive tape, and the temperature sensor probe compresses tightly the contact with the fish bowl outer wall, produces the change when the fish bowl temperature, and the temperature sensor probe with the fish bowl contact gives temperature controller with the temperature signal transmission that detects, and temperature controller shows temperature value on the display screen of thermometer, if the temperature is not in the temperature interval of settlement simultaneously, temperature controller then controls the alarm and sends out the police dispatch newspaper.

However, the existing stuck fish tank thermometer often has the problem of loose contact at the contact position of the temperature sensor probe and the fish tank, which results in inaccurate monitoring and even failure of the thermometer, because the double-sided adhesive tape used for sticking has certain resilience: when the temperature sensor probe is adhered to the fish tank, the temperature sensor probe is in close contact with the fish tank, but the double-sided adhesive tape slightly rebounds in the later period of time, so that a gap is formed between the temperature sensor probe and the outer wall of the fish tank.

In order to solve the problem of poor contact of the adhesive fish tank thermometer, the thermometer adhered to the outer wall of the fish tank is designed, and the temperature sensor probe is always tightly attached to the outer wall of the fish tank through the built-in elastic structure, so that temperature monitoring is more accurate.
