Abstract
The utility model discloses a drinking fountain and an anti-dry device thereof. The anti-dry device comprises a switching part and a water-level sensor, wherein the switching part and a power circuit of an electronic heating part of the drinking fountain are connected in series and the water-level sensor is arranged inside a tank container of the drinking fountain. The water-level sensor and the switching part are electronically connected to control the connection or disconnection of the switching part. According to this arrangement, the switch part is controlled to disconnect when the water level of the tank container is less than a preset value, so that the electronic heating part stops heating to achieve the anti-dry effect and improve the safety in use the drinking fountain.
Description
Technical field
The utility model relates to vessel to boil water, particularly relates to a kind of anti-parching device for drinking device and has its water dispenser.
Background technology
Water dispenser is one of electrical equipment of generally using such as family, office space.Current such a problem of water dispenser ubiquity on the market: water fountain heater switch is opened the rear most of the time in unmanned cooking state, when the water in drinking water barrel racks up, while not being able to do in time again one barrel, new clothes, water dispenser power-off in time, easily there is dry combustion method, thereby have the potential safety hazard that causes water dispenser spontaneous combustion.
Summary of the invention
For above-mentioned prior art present situation, technical problem to be solved in the utility model is, a kind of anti-parching device for drinking device is provided, the security of using to improve water dispenser.Another technical problem to be solved in the utility model is, a kind of water dispenser with this anti-dry burning device is provided.
In order to solve the problems of the technologies described above, a kind of anti-parching device for drinking device provided by the utility model, described anti-dry burning device comprises switch block and liquid level sensor, described switch block is connected on the power circuit of electric heating element of described water dispenser, described liquid level sensor is arranged in the water tank container of described water dispenser, and described liquid level sensor and the electrical connection of described switch block, for controlling conducting and the disconnection of described switch block.
In an embodiment, described liquid level sensor is floating ball type liquid level sensor therein.
Therein in an embodiment, described liquid level sensor comprises liquid level sensor body and magnet ring ball float, described liquid level sensor body is vertically arranged in described water tank container, and in described liquid level sensor body, be provided with tongue tube, described magnet ring ball float is set in the outside of described liquid level sensor body and can moves up and down.
In an embodiment, described switch block is relay therein, and the coil of this relay is connected with described liquid level sensor, and the normally-closed contact of this relay is connected on described power circuit.
A kind of water dispenser provided by the utility model, comprises above-mentioned anti-dry burning device.
Compared with prior art, anti-parching device for drinking device provided by the utility model and there is its water dispenser, when the water level of the water tank container of water dispenser is during lower than setting value, liquid level sensor gauge tap parts disconnect, thereby electric heating element stops heating, when final realization is not enough to high water tank, anti-dry object, improves the security that water dispenser is used.Anti-parching device for drinking device of the present utility model, by simulating continuously lack of water experiment for 100 times, and burst topples over water tank checking, can be at internal cutting off in 2 seconds heating power supply.

The specific embodiment
Below with reference to accompanying drawing, also the utility model is elaborated in conjunction with the embodiments.It should be noted that, in the situation that not conflicting, the feature in following embodiment and embodiment can combine mutually.
As Fig. 1, anti-parching device for drinking device in one of them embodiment of the utility model, comprise liquid level sensor 10 and switch block, described switch block is connected on the power circuit of water dispenser electric heating element 40, described liquid level sensor 10 is positioned at the water tank container of water dispenser, and described liquid level sensor 10 is connected with described switch block, for conducting and the disconnection of gauge tap parts.When the water level of the water tank container of water dispenser is during lower than setting value, liquid level sensor 10 gauge tap parts disconnect, thereby electric heating element 40 stops heating, finally realize anti-dry object when not enough to high water tank, improve the security that water dispenser is used.
More preferably, described liquid level sensor 10 is floating ball type liquid level sensor 10.Figure 2 shows that the structural representation of floating ball type liquid level sensor 10, described liquid level sensor 10 comprises liquid level sensor body 11 and magnet ring ball float 12, described liquid level sensor body 11 is vertically arranged in described water tank container, and in described liquid level sensor body 11, be provided with tongue tube 11a, described magnet ring ball float 12 is set in the outside of described liquid level sensor body 11 and can moves up and down.
More preferably, described switch block is relay, this relay pack vinculum circle 20 and normally-closed contact 30, and this coil 20 is connected with described liquid level sensor 10, and this normally-closed contact 30 is connected on the power circuit of described electric heating element 40.
The operation principle of the anti-parching device for drinking device in the present embodiment is as follows: liquid level sensor body 11 is bolted in water tank container, and be set to reference water place value with this, when the water level in water tank container is during lower than datum level, magnet ring ball float 12 drops to bottom, liquid level sensor body 11 output low levels (seeing Fig. 3), the normally opened contact of relay disconnects, thereby controls electric heater primary power source de-energizes; When the water level in water tank container is during higher than datum level, magnet ring ball float 12 is raised to top, and liquid level sensor body 11 is exported high level (seeing Fig. 3), and relay normally open contact closure is normally worked thereby control electric heater main power source.
In another embodiment of the utility model, provide a kind of water dispenser, include the anti-dry burning device in above-described embodiment.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
