The patent No. is to disclose a kind of " steam cleaner " technical scheme for the Chinese utility model patent of CN2573097Y (hereinafter referred patent documentation 2) ZL02248889.8, Granted publication number, this patent documentation 2 has disclosed the technology contents of a kind of " heat generating core ", the venthole 21 that is somebody's turn to do " heat generating core " is connected to vapor injection port 2 by steam outlet pipe 14, by venthole 21 steam is flowed to vapor injection port 2 during work and discharges.
In conjunction with putting into practice and anatomize above-mentioned two patent documentations; as seen there is following defective in the two: no matter be " steam generator " of patent documentation 1 or " heat generating core " of patent documentation 2; safeguard measure is not all taked in its discharging to steam, has elevated pressures and reach " heat generating core " inside at " steam generator " owing to exist vaporescence to make " steam generator " reach " heat generating core " inside.Therefore in use may exist just in case obstruction can not pressure release and cause " steam generator " reach " heat generating core " interior steam can not in time discharging,, jeopardize personal safety then there is explosion danger; In addition, no matter be the vapor opening 11 of patent documentation 1 or the venthole 21 of patent documentation 2, all the pressure of steam not to be controlled and directly discharging, the steam pressure shakiness that causes discharging causes cleaning, sterilization, decontamination not good.
The utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition be overcome existing heat generating core can not pressure release and exist the steam pressure shakiness of explosion danger and discharge to cause cleaning, sterilization, the not good defective of decontamination, a kind of heat generating core that has pressure relief device is provided.For this reason, the utility model is by the following technical solutions:
The heat generating core that has pressure relief device, it is heater to be set in the inner space of housing and water inlet and venthole are set on housing, it is characterized in that on described venthole, establishing a pressure relief device, this pressure relief device comprises the end cap of a sealing block, a compression spring and a band steam discharge interface, described end cap is connected on the described housing, and described compression spring remains on described sealing block elasticity on the described venthole.
As the optimization technique measure, have the ring rib that is positioned at around the described venthole outer end on the described housing, described sealing block contact is on described ring rib.
As the optimization technique measure, described sealing block has a coniform guidance part, and this guidance part extends in the described venthole, and is provided with the circular cone guide hole corresponding with described guidance part in the described venthole.Further, offer the steam discharge groove vertically on the inwall of described venthole.
As the optimization technique measure, putting between described end cap and the described housing has sealing ring.
The utility model is by establishing a pressure relief device on venthole, by this pressure relief device to the control of steam pressure after more outwards (as the vapor injection port 2 of the nozzle 5 or the patent documentation 2 of patent documentation 1) carry, can reach following beneficial effect:
1, in use just in case stop up, can the steam in the heat generating core be discharged pressure release, avoid explosion danger, jeopardize personal safety by pressure relief device.
2, the steam in the heat generating core outwards can be discharged according to the pressure of setting, pressure stability guarantees cleaning, sterilization, clean effect.
3, pressure relief device utilizes the structure of housing to form, and simple and compact for structure, volume is little.
Description of drawings
Fig. 1 is the cross-sectional view that the utility model has the heat generating core of pressure relief device.
Fig. 2 is the structural representation of the utility model pressure relief device.
Fig. 3 is the A portion enlarged drawing of Fig. 2.
The number in the figure explanation: the 1-housing, the 2-heater, the 3-water inlet, the 4-venthole, the 5-pressure relief device, the 6-sealing block, the 7-compression spring, 8-steam discharge interface, the 9-end cap, 10-encircles rib, 11-guidance part, 12-guide hole, 13-steam discharge groove, 14-sealing ring.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further.
The heat generating core that has pressure relief device of the present utility model, as shown in Figure 1, it is heater 2 to be set and water inlet 3 and venthole 4 are set on housing 1 in housing 1 (the diagram housing is that upper and lower two and half housings assemble) inner space, on venthole 4, establish a pressure relief device 5, this pressure relief device 5 (referring to Fig. 2) comprises the end cap 9 of a sealing block 6, a compression spring 7 and a band steam discharge interface 8, end cap 9 connects (as by being threaded) on housing 1, and compression spring 7 remains on sealing block 6 elasticity on the venthole 4.This heat generating core, when transporting water stream is through heater 2 heating generation steam in heat generating core by water inlet 3, because compression spring 7 remains on sealing block 6 elasticity on the venthole 4, therefore venthole 4 is temporarily by shutoff and can not steam discharge, along with producing increasing of steam in the heat generating core, steam pressure raises, until the elastic force that can overcome described compression spring 7 and sealing block 6 can be pushed open from venthole 4 and opened venthole 4, released vapour, so the steam that discharges has certain pressure (therefore this pressure can determine the pressure of steam ports 4 released vapours by the compression spring of selecting different elastic force for use by the elastic force decision of compression spring 7) and this pressure can keep stable; And, just in case stop up, can the steam in the heat generating core be discharged pressure release by pressure relief device 5, avoid explosion danger, jeopardize personal safety.The steam that discharges with certain pressure from venthole 4 further through be connected on the steam discharge interface 8 steam pipework more outwards (as the vapor injection port 2 of the nozzle 5 or the patent documentation 2 of patent documentation 1) carry for cleaning, sterilization, decontamination.
As further improving and replenishing to technique scheme, the utility model also comprises following additional technical characterictic, though Fig. 1-3 has comprised following all additional technical features, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected for use on the described technical scheme of epimere when implementing the utility model:
Have on the housing 1 and be positioned at venthole 4 outer ends ring rib 10 on every side, sealing block 6 contacts are on ring rib 10 (referring to Fig. 3), form contacting of the theoretic line seamed edge of rib (ring) and face (sealing surface on the sealing block) thus, guarantee that sealing is reliable, can not leak, the section configuration that therefore should encircle rib can be multiple shapes such as triangle, semicircle.
Putting between end cap and the housing 1 has sealing ring 14, guarantees sealing.
