Abstract
The utility model relates to a water-proof button structure used on the control panel of the bathing device. The utility model mainly solves the technical problems of the sealing water resistance between the outer casing of the control panel and the button installed on the outer casing. Therefore, a plastic surrounding frame is arranged in the button area at the inner side of the outer casing, and connected with the matched plastic pressing plate and the soft button pad in a sealing way, the light touch switch pushing rod in the area is connected with the inner side of the button pad, the outer side is connected with the inner end of the plastic buttons through the button grains, and the outer ends of the plastic buttons are slightly bulged above the corresponding round holes on the outer casing. The utility model is mainly used on the computer steam room and the electric massaging bathtub.
Description
Technical field
The utility model relates to technical field of bathroom equipment, the Waterproof push-button structure that particularly a kind of sanitary bath equipment control panel is used.
Background technology
Sanitary bath equipments such as existing vaporium, electric massage bathtub, because the needs of waterproof, the plastic film chip architecture is pasted on the general surface of adopting of its control panel button part, with the effect that reaches waterproof and transmit key command.Described control panel is made of rigid plastics diaphragm 1, button cap 2, shell 3, touch-switch 4, push rod 5, control circuit board 6, inner chamber 7, referring to shown in Figure 1.Inner chamber 7 is formed by shell 3 sealings, and touch-switch 4 is welded on the control circuit board 6, and this wiring board 6 is fixed in the shell 3, and button cap 2 is enclosed within on the push rod 5 of touch-switch 4.Shell 3 is provided with key hole, button cap 2 pack into its round end of back expose shell a little, press with hand and then to promote push rod 5 action.Owing between shell key hole 5 and the button cap 2 slit is arranged, and inner chamber 7 needs sealing, therefore must paste one deck rigid plastics diaphragm at shell 3 button part faces, itself and the protruding round platform in button cap 2 contact positions are with the cooperation button cap.When push this boss platform with hand, then transmit pressure to push rod 5 by button cap 2, touch-switch 4 closures, control circuit work realizes control procedure.There is following weak point in said structure: 1. long-term constantly press by and hygrothermal environment under, the rigid plastics diaphragm is aging easily, embrittlement or break, thereby loses waterproof effect.2. the chamber internal gas pressure with rigid plastics diaphragm sealing just alters a great deal with temperature, and adhesive surface is in the pressure of variation for a long time, adds the abominable environment for use and the erosion of steam, make adhesive aging, lost efficacy and caused infiltration.3. adopt the rigid plastics diaphragm to make waterproof and hold concurrently to transmit key command, its boss platform can damage after pressing certain number of times, or depression go down can not resilience, make key-press from false action.Button cap entangles push rod in addition, and push rod also bears side force and torsion simultaneously when pressing, and causes touch-switch fragile, the machine-spoiled rate height.4. owing to adopt the plastic film chip waterproof construction, thereby the design and the innovation of product appearance have been limited.
Summary of the invention
The technical problems to be solved in the utility model is to have reliable, durable water-tight structure between the shell of sanitary bath equipment control panel and thereon the button of dress.
The utility model proposes following technical solution: the Waterproof push-button structure that a kind of sanitary bath equipment control panel is used, comprise shell 14, touch-switch 15, push rod 16, control circuit board 17, shell 14 sealings form inner chamber 20, touch-switch 15 is welded on the control circuit board 17, this wiring board 17 is packed in the shell 14, be provided with plastics in described shell 14 domestic demands dress key area and enclose frame 12, also be provided with plastic presser plate 11 and soft button piece 19, soft button piece 19 peripheries are embedded in the groove of plastic presser plate 11 peripheries, and be packed in plastics by screw and enclose on the frame 12; Button grain 18 inboards contact with the push rod 16 of touch-switch 15 by soft button piece 19, and button grain 18 outsides contact with plastic key 13 the inners, and these plastic key 13 outer ends protrude from outside shell 14 corresponding circle holes slightly.
Compared with prior art, the utlity model has following beneficial effect: because the employing hermetically-sealed construction is kept apart touch-switch and control circuit board and plastic key in the key area in the enclosure, guarantee that each electric component leaves moist adverse circumstances, makes the button of control panel really reach waterproof, durable, reliable effect.Owing between rigid plastics button and push rod, be connected to soft button grain and button piece, realize the soft transmission of instruction, its degree of transitivity can infinitely promote, and push rod is subjected to side force and torsion minimum, not fragile, touch-switch reliability height.Simultaneously, plastic key can plate metal colors such as gold, silver color, improves its decorative effect greatly, and product specification also greatly improves.
The utility model is mainly used on computer steam chamber and the electric massage bathtub.
Description of drawings
Fig. 1 is the waterproof press-button structural representation that existing a kind of sanitary bath equipment control panel is used.
Fig. 2 is the shown waterproof press-button structural representation of embodiment of the utility model.
Embodiment
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 2, the Waterproof push-button structure that the sanitary bath equipment control panel of present embodiment is used is by forming with lower member: plastic presser plate 11, plastics enclose frame 12, plastic key 13, shell 14, touch-switch 15, push rod 16, wiring board 17, button grain 18, soft button piece 19, inner chamber 20.Earlier soft button piece 19 is attached on the plastic presser plate 11 during installation, by screw plastic presser plate 11 and plastics is enclosed frame 12 pressings, then the soft button piece 19 of pressing place has the sealing ring effect, and inner chamber 20 and external isolation are come; Button grain 18 inboards join by the push rod 16 of soft button piece 19 with touch-switch 15, its outside and plastic key 13 interior end in contact, and plastic key 13 outer ends protrude from shell 14 corresponding circle holes slightly.Press plastic key 13,18 of button grains are as middle soft transmission mechanisms, and the downforce of plastic key 13 is conducted on the touch-switch 15, realize the circuit control procedure.This sealing structure effect is remarkable, and no steam infiltrates in 72 hours in 2 standard atmospheric pressures, 80 degrees centigrade steam; It is normal that button is pressed 20,000 each device functions continuously.The test effect confirms that this structural behaviour is reliable, best in quality.
