Abstract
The utility model discloses an electric heat type exhaust port used for a water tank. The electric heat type exhaust port used for the water tank comprises an exhaust port body. The exhaust port body is provided with a middle portion limit edge and an upper portion limit edge. The lower portion of the exhaust port body is provided with external threads which are used for being connected with the water tank and the top portion of the exhaust port body is provided with external threads and matches with a cover which is provided with internal threads. The electric heat type exhaust port used for the water tank is characterized in that an electrothermal membrane is arranged between the cover and the upper portion limit edge, a breathable groove is formed in the electrothermal membrane, and the electrothermal membrane is connected with a power supply which is presetted on one side of the water tank through wires. Due to the technical scheme, the electric heat type exhaust port used for the water tank has the advantages of being simple in structure and capable of effectively preventing outside cool air from entering the inner portion of the water tank, ensuring that the temperature of the inner portion of the water tank is kept at a suitable temperature in a long time due to the fact that the outside cool air is heated by the electrothermal membrane and is exchanged with the air in the inner portion of the water tank, being free from heating water in the inner portion of the water tank and reducing use cost.
Description
Technical field
The utility model relates to the water tank apparatus field, particularly a kind of electroheating type exhaust opening for water tank.
Background technology
At present, all can be provided with an exhaust opening on the water tank, exhaust opening is generally the ventilative pipeline in a two, one end of exhaust opening is communicated with water tank, the other end of stack is positioned at the water tank outside and is communicated with outside air, so just can guarantee pressure and extraneous pressure balance in the water tank, make water tank normal operation retaining.
But in the lower place of temperature, water tank is inner directly to be contacted with outside air if directly allow, and extraneous cold air can make the water freezing of water tank inside, causes being inconvenient to use, and needs the water of water tank inside is heated, and increases use cost.
In sum, for deficiency and the defective of existing water tank, need especially a kind of pollutant that can prevent to enter into the exhaust opening that water tank can make again water tank inside be communicated with outside air, address the above problem.
The utility model content
Technical problem to be solved in the utility model is for shortcomings and deficiencies of the prior art, and a kind of electroheating type exhaust opening for water tank is provided, and this electroheating type exhaust opening can prevent effectively that cool ambient air from directly entering into water tank inside.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of electroheating type exhaust opening for water tank, comprise the exhaust opening body, be provided with middle part position-limited edge and top position-limited edge on the described exhaust opening body, described exhaust opening body bottom is provided with the external screw thread that is connected for water tank, described exhaust opening bodies top be provided with external screw thread and with one female lid be set be used, it is characterized in that, be provided with Electric radiant Heating Film between described lid and the described top position-limited edge, be provided with ventilative groove on the described Electric radiant Heating Film, described Electric radiant Heating Film is connected with the power supply that is preset in water tank one side by wire.
Preferably, the soffit of described middle part position-limited edge is provided with rubber washer.
Preferably, the width of described ventilative groove is 4mm.
Owing to adopted above-mentioned technical scheme, the utility model is simple in structure, can prevent effectively that cool ambient air from directly entering into water tank inside, cool ambient air through behind the heated by electrothermal film again with the interchange of air of water tank inside, guarantee that the water tank internal temperature is in a suitable temperature for a long time, need not special water to water tank inside and heat, reduced use cost.
Description of drawings
Fig. 1 is the structural representation of a kind of electroheating type exhaust opening for water tank of the utility model.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Fig. 3 is the top view of Electric radiant Heating Film.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Extremely shown in Figure 3 referring to Fig. 1, a kind of electroheating type exhaust opening for water tank comprises exhaust opening body 10, be provided with middle part position-limited edge 20 and top position-limited edge 21 on the exhaust opening body 10, exhaust opening body 10 bottoms arrange external screw thread 30, the soffit of middle part position-limited edge 20 is provided with rubber washer 30, exhaust opening body 10 is connected with water tank by the external screw thread 30 of bottom, and conflicts with the rubber washer 31 of middle part position-limited edge 20 soffits, makes water tank have good tightness.
The top of exhaust opening body 10 and lid 40 are threaded connection and are used, be provided with circular Electric radiant Heating Film 50 between lid 40 and the top position-limited edge 21, circumferentially circumferentially be arranged at intervals with the ventilative groove 51 that some width are 4mm on the Electric radiant Heating Film 50, Electric radiant Heating Film 50 is connected with the power supply that is preset in water tank one side by wire.
The electroheating type exhaust outlet structure that should be used for water tank is simple, can prevent effectively that cool ambient air from directly entering into water tank inside, cool ambient air through Electric radiant Heating Film 50 heating after again with the interchange of air of water tank inside, guarantee that the water tank internal temperature is in a suitable temperature for a long time, need not special water to water tank inside and heat, reduced use cost.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
