Abstract
The utility model discloses an anti-empty-burning device of a liquid heater. The device comprises a shell in which a cavity is formed, wherein a water inlet and a water outlet which are communicated with the cavity are formed in the shell, a reed pipe is arranged on the top of the cavity, a floating ball capable of moving up and down along the reed pipe is arranged outside the reed pipe in a sleeved mode, and a magnet is arranged in the floating ball. The anti-empty-burning device of the liquid heater is mainly applied to a liquid heating device such as an instant heating water heater and is installed on a liquid delivery pipeline in the front of the water heater, water flow first passes through the anti-empty-burning device and then enters the heater, and when the water flow flows through the anti-empty-burning device, the floating ball floats up, and the heater works normally; when water is stopped, the floating ball descends, the reed pipe outputs a control signal to make the heater stop working, the heater is prevented from performing empty burning, and the heater is effectively protected.
Description
Technical field
The utility model relates to the anti-empty burning device of a kind of anti-empty burning device, particularly a kind of liquid heater.
Background technology
Existing immediately heating water heater is to adopt the mode of burning to heat the water flowing through, and makes its temperature increase, but empty phenomenon of burning may appear in this immediately heating water heater, has a strong impact on the performance and used life of water heater, and has safe hidden danger.
Utility model content
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of anti-empty burning device of liquid heater, can effectively prevent that the sky of the liquid heaters such as water heater from burning phenomenon.
The technical scheme that the utility model adopts is mainly:
A kind of anti-empty burning device of liquid heater, comprise that inside is provided with the housing of cavity, be provided with the water inlet and the delivery port that are communicated with cavity on described housing, described cavity top is provided with tongue tube, tongue tube is arranged with the ball float that can move up and down along tongue tube outward, and ball float inside is provided with magnet.
As the further improvement of technique scheme, described water inlet is arranged on lower housing portion, and delivery port is arranged on housing top.
Further improvement as technique scheme, is provided with baffle plate in described cavity, and further, the water channel that the described baffle plate near delivery port is obliquely installed and makes this baffle plate and inner walls to form broadens gradually.
The beneficial effects of the utility model are:
Anti-empty burning device of the present utility model is mainly used in the Instant heating type liquid heating such as water heater, it is arranged on the liquid-transport pipe-line before heater, and current first enter heater again through anti-empty burning device, when current are flowed through anti-empty burning device, ball float floats, heater normal operation; When occurring cutting off the water supply, ball float declines, and tongue tube output control signal stops heater, prevents that heater from carrying out sky and burning, and effectively protects heater.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
With reference to Fig. 1, it is the preferred embodiment that the utility model provides, a kind of anti-empty burning device of liquid heater, comprise that inside is provided with the housing 1 of cavity 2, on housing 1, be provided with the water inlet 3 and the delivery port 4 that are communicated with cavity 2, water inlet 3 is arranged on housing 1 bottom, delivery port 4 is arranged on housing 1 top, in cavity 2, be provided with baffle plate 7, baffle plate 7 forms water channel with cavity 2 inwalls, cavity 2 tops are provided with tongue tube 5, and tongue tube 5 is outer is arranged with the ball float 6 that can move up and down along tongue tube 5, and ball float 6 inside are provided with magnet.
Anti-empty burning device of the present utility model is mainly used in the Instant heating type liquid heating such as water heater, it is arranged on the liquid-transport pipe-line before heater, and current first enter heater again through anti-empty burning device, when current are flowed through anti-empty burning device, ball float 6 floats, heater normal operation; When occurring cutting off the water supply, ball float 6 declines, and tongue tube 5 output control signals stop heater, prevents that heater from carrying out sky and burning, and effectively protects heater.
Further, the water channel that is obliquely installed and makes this baffle plate 7 and housing 1 inwall to form near the baffle plate 7 of delivery port 4 broadens gradually, in the time of can preventing that current are too urgent, at the interior generation of cavity 2 stream that backwashes, affects ball float 6 and drifts along.
The foregoing is only preferential embodiment of the present utility model, as long as within the technical scheme that realizes the utility model object with basic identical means all belongs to protection domain of the present utility model.
