Abstract
The utility model discloses an electric faucet capable of preventing frost splitting. The electric faucet comprises a heating cylinder body and an end cover, wherein a water inlet and a water outlet are formed on the heating cylinder body, and a heating pipe is fixedly arranged inside the heating cylinder body. The electric faucet capable of preventing frost splitting is characterized in that a reserved space extension mechanism is arranged inside the heating cylinder body, and is positioned between the heating pipe and the end cover; the electric faucet has the advantages that the reserved space extension mechanism is arranged between the heating pipe and the end cover, after water inside the heating cylinder body freezes, the expanded part of the volume can be released inside the reserved space of the extension mechanism by compressing the reserved space extension mechanism, so as to prevent the electric faucet from frost splitting, and ensure the use safety.
Description
Technical field
The utility model relates to a kind of water tap, relates in particular to a kind of electric hot water tap of preventing bursting by freezing.
Background technique
Electric hot water tap is a kind of water tap that carries heating equipment, also is a kind of water heater of water outlet open type, when some temperature are lower than 0 ℃ occasion use; The going out of electric hot water tap, water inlet can freeze prior to heating cavity; And making heating cavity partly form an airtight space, the volumetric expansion because water build-ups ice usually has water tap to be taken place by bursting by freezing or freezing situation; Cause electric hot water tap to leak or leak electricity, bring certain potential safety hazard to the user.
Summary of the invention
The utility model technical problem to be solved provides a kind of electric hot water tap of preventing bursting by freezing.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of electric hot water tap of preventing bursting by freezing; Comprise heating cylindrical shell and end cap; Described heating cylindrical shell is provided with water intake and water outlet; Described heating cylindrical shell internal fixation is provided with heating pipe, is provided with the headspace extending means in the described heating cylindrical shell, and described headspace extending means is between described heating pipe and described end cap.
Described headspace extending means comprises slide block and flexible restoring organ; Be wholely set the gear ring on the inwall of described heating cylindrical shell; Described slide block sealing is arranged in the described heating cylindrical shell; The front-end face of described slide block withstands on the described gear ring; Described flexible restoring organ is arranged between the internal surface of ear end face and described end cap of described slide block, and the distance of the internal surface of the ear end face of described slide block to described end cap is more than or equal to the build-up ice ratio of interior cross-section area of volume that the back increased and heating cylindrical shell of the water in the described heating cylindrical shell.
The diameter of described slide block is slightly less than the internal diameter of described heating cylindrical shell, is provided with O type circle between the circumferential surface of described slide block and the described heating cylindrical shell.
Described flexible restoring organ is a Returnning spring.
Described flexible restoring organ is the sponge that is fixedly installed on the described slide block ear end face.
Compared with prior art; The utility model has the advantages that owing to be provided with the headspace extending means between heating pipe and the end cap; After the water in the heating cylindrical shell build-ups ice; The volume of its dilation can be released in the headspace of this extending means through compression headspace extending means, thereby prevents electric hot water tap by bursting by freezing, guarantees the Security of its use.
Description of drawings
Fig. 1 is the utility model embodiment one a structural representation;
Fig. 2 is the utility model embodiment two a structural representation.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one: as shown in the figure; A kind of electric hot water tap of preventing bursting by freezing comprises heating cylindrical shell 1, end cap 2 and slide block 4, and heating cylindrical shell 1 is provided with water intake 11 and water outlet 12; Heating cylindrical shell 1 internal fixation is provided with heating pipe 3; Be wholely set gear ring 13 on the inwall of heating cylindrical shell 1, slide block 4 is arranged in the described heating cylindrical shell 1 and between heating pipe 3 and end cap 2, and the diameter of slide block 4 is slightly less than the internal diameter of heating cylindrical shell 1; Be provided with O type circle 5 between the circumferential surface of slide block 4 and the heating cylindrical shell 1; The front-end face of slide block 4 withstands on the gear ring 13, is provided with Returnning spring 6 between the internal surface of the ear end face of slide block 4 and end cap 2, the ratio of the volume that the distance L of the internal surface of the ear end face of slide block 4 to end cap 2 is increased after build-uping ice more than or equal to the water in the heating cylindrical shell 1 and the interior cross-section area of heating cylindrical shell 1.
Embodiment two: as shown in the figure, other structure is with embodiment one, and difference is to have substituted Returnning spring 6 with sponge 7, and sponge 1 is fixedly installed on the ear end face of slide block 4.
