The specific embodiment
Embodiment one, and this enforcement proposes the anti-dismounting of a kind of knob structure, comprises knob 100 and temperature controller 500, and said temperature controller 500 is installed in the end cap 300 through temperature controller support 200.
Said knob structure is with reference to figure 1, and this knob 100 comprises spiral cover 103, axle sleeve 101 and be symmetricly set on a pair of elastic card claw 102 of axle sleeve both sides that said claw 102 is half arrow-shaped.
Said temperature controller supporting structure is with reference to figure 2; Wherein the Elastic buckle structure can be with reference to the enlarged drawing among the figure 3, and the fit structure of knob and temperature controller can be with reference to figure 4 and Fig. 5, shown in above-mentioned figure; This temperature controller support 200 comprises a panel 207; Be provided with knob jack 201 by midway on this panel 207, for knob 100 on claw 102 cooperate, the end of this knob jack 201, is along being provided with a circle claw backstop 206.In addition, knob jack 201 peripheries are provided with a circle groove 208, and groove structure can be with reference to figure 2 and Fig. 5; After said knob was installed on the said temperature controller, the root edge 1031 of said spiral cover embedded in the said groove 208, and this groove plays the effect that makes things convenient for the knob rotation on the one hand; On the other hand, during water pouring test, play the effect of catchmenting; When having avoided the trickle experiment, a part of water gets into the internal electrical air chamber from the knob jack.
With reference to figure 4, temperature controller 500 is fixing for ease, and the periphery of said knob jack 201 is arranged with two screw holes 204; Temperature controller is installed for ease, improves installation effectiveness, and panel 207 back sides are provided with the temperature controller location structure, and the present embodiment location structure comprises 7 stepped reference columns 203 that are arranged on said knob jack 201 peripheries; Indicator lamp is installed for ease, also is provided with indicator lamp installing hole 205 on the said panel, and wherein, described indicator lamp plays the effect of duty prompting.For the easy accessibility between temperature controller support and the end cap; Be arranged with two pairs of buckles 202 on the both sides of the edge of said panel 207; Present embodiment buckle 202 as figure are " H " shape; Promptly comprise two vertical beams and middle retaining beam 2022, connect a plectrum 2021 on the retaining beam between wherein, this plectrum 2021 is one-body molded with buckle 202.
During installation;, at first temperature controller 500 is fixed on the temperature controller support 200 to Fig. 9 with reference to figure 6, is about to temperature controller 500 and places the position of panel 207 back side reference columns 203 qualifications to realize preparatory installing and locating; Be fixed through screw hole 204, this moment, knob jack 201 was stretched out in the temperature controller rotating shaft again; Axle sleeve 101 with knob 100 is enclosed within the said rotating shaft then, and pushes knob, and meanwhile elastic card claw 102 produces deformation; Up to being seated, claw 102 is stuck on the claw backstop 206, and recovers deformation; Like this; Claw 102 cooperates with claw backstop 206, and knob can not extracted through the mode that pulls easily by domestic consumer, thereby has realized the anti-dismounting of knob; Through the buckle backstop 301 on buckle on the temperature controller support 200 202 and the end cap 300 temperature controller support 200 is installed on the end cap 300 more at last.
During the maintenance dismounting, at first temperature controller support 200 is disassembled from end cap 300, thereby promptly the buckle backstop 301 generation deformation on the end cap are separated with Elastic buckle 202, can it be taken off through the elastic plectrum of stirring on the Elastic buckle 202 2201; Through flat mouthful of instrument such as screwdriver knob claw 102 is taken off from the cooperation place of itself and claw backstop 206 then, temperature controller 500 is unloaded from temperature controller support 200 get final product at last.
Need to prove; Present embodiment elastic card claw and Elastic buckle all are not limited to the said structure form; Any version of buckle backstop that can realize all can be used for the utility model; For example elastic card claw 102 also can be arranged to the cylinder that an outside has draw-in groove, and it is protruding that the backstop 206 that is mated can be arranged on the circle of one on said knob jack 201 inwalls.Certainly, Elastic buckle and buckle backstop are also blocked other forms of employing, and this does not give an example one by one.
In order accurately to adjust temperature; Round-meshed square plate film 400 in the middle of present embodiment also comprises one, this dish film is mounted on said panel 207 surfaces, and coiling film 400 can play decoration function to whole front panel 207 on the one hand; Can have scale on it on the other hand, make things convenient for knob accurately to adjust water temperature.After adding the sabot mould, need to coil film earlier before the dismounting and take away,, conveniently temperature controller support 200 is disassembled from end cap 300 so that expose Elastic buckle.
The anti-dismounting of the knob of the utility model structure has realized the on-dismountable of knob through the claw and the fit structure thereof of mutual buckle, and it is simple in structure, and cost is lower, and is easy for installation, effectively improves the product overall performance.
Embodiment two, and this enforcement proposes a kind of water heater, comprise implementing the anti-dismounting of described knob structure, cooperate through temperature controller support employing claw between knob wherein and the temperature controller; When knob, drive the temperature controller rotating shaft and rotate, on the one hand; Realized the temperature adjustment function of water heater, on the other hand, claw cooperates; Domestic consumer can't dismantle, and guarantees that knob is on-dismountable parts, thereby has satisfied the water pouring test requirement.Buckle structure between temperature controller support and the water heater end cap has greatly made things convenient for the dismounting of maintenance personal to it in addition, has improved dismounting efficient.
Certainly, the anti-dismounting of described knob structure equally also can be applied in other electronic equipments such as air-conditioner, and the utility model is not limited thereto.
Above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
