The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 2-4, the electric heating faucet provided in this embodiment includes a main body 1, and the main body 1 is provided with a water inlet 2 and a water outlet communicated with an internal flow channel, in this embodiment, there are two water outlets, a cold water outlet 3 and a hot water outlet 4.
A tap switch 5 for opening and closing the water outlet, an electronic device and a heating water tank 6 are transversely and sequentially arranged on the main body 1.
A heating member 7 is provided in the heating water tank 6 to heat the water flowing through the internal flow passage from the water inlet 2 into the heating water tank 6 to be hot water. The electronic device comprises an on-off switch 8 for controlling the heating component 7 to be turned on and off, a controller and the like. The on-off switch 8 is positioned at the side of the heating water tank 6.
The tap switch 5 comprises a valve core, and the valve core can intervene the on-off state between the water inlet 2 and the water outlet through rotation.
As shown in fig. 4, a water pressure switch 10 is disposed at a side portion of the heating water tank 6, the heating water tank 6 is provided with a mounting hole adapted to an outer contour of the water pressure switch 10, and the water pressure switch 10 is sealingly disposed in the mounting hole, so that the water pressure switch 10 and the heating water tank 6 maintain good sealing performance.
The hydraulic switch 10 has one side facing the inside of the heating water tank 6 and the other side facing the on-off switch 8. When the water level of the heating water tank 6 is gradually increased, the pressure applied to the hydraulic switch 10 is gradually increased, and thus the water is gradually deformed toward the side of the on-off switch 8. The deformation amount of the water pressure switch 10 is positively correlated with the water level of the heating water tank 6. Preferably, the on-off switch 8 is a microswitch.
As shown in fig. 5 and 6, the hydraulic switch 10 includes a resilient cap 11 and a rigid push-contact member 12, wherein the resilient cap 11 is made of a resilient material such as silicone rubber or rubber, and can be deformed under hydraulic pressure to recover its original shape after removing an acting force. The rigid top contact piece 12 has high compressive strength, is hard and not easy to deform and is used for touching the on-off switch 8 of the heating circuit.
Specifically, as shown in fig. 7 to 9, the elastic cap 11 includes a cap body 101, and the cap body 101 includes a bottom a and a peripheral side portion b extending by bending around an edge of the bottom, wherein the peripheral side portion b is connected to the mounting hole of the heating water tank 6. The force of the water is mainly concentrated on the bottom a of the cap body 101. When the inner side of the bottom a of the cap body 101 is acted by water pressure, it arches outward; when the water pressure is reduced to disappear, the water pressure is gradually restored to be deformed inwards.
In particular, the elastic cap 11 further comprises a boss 102 protruding outward from the bottom a of the cap body 101, the boss 102 extending in a direction away from the peripheral side portion, the cap body 101 and the boss 102 being integrally formed. The rigid top contact 12 and the convex column 102 are matched and sleeved outside the convex column 102.
The bottom a of the cap body 101 of the elastic cap 11 is deformed outward by the inner water pressure, so that the convex post 102 drives the rigid push contact 12 to push out, and the outer end surface of the rigid push contact 12 acts on the on-off switch 8 of the heating circuit.
In this embodiment, as shown in fig. 8, the rigid top contact 12 has a cavity C matching the outer profile of the convex cylinder 102, and is sleeved outside the convex cylinder 102 through the cavity C. The boss 102 is tapered in diameter from inside to outside, and the boss 102 is pressed with interference into the concave cavity C of the rigid top contact 12.
Further preferably, the rigid contact member 12 has a cup-shaped structure with one side open and the other side closed, and the outer end surface of the rigid contact member 12 is a flat surface.
Of course, it should be noted that the rigid top contact 12 may also have an annular column structure, and when the rigid top contact 12 is fitted over the post 102, the outer end face of the rigid top contact 12 is flush with the outer end face of the post 102, or exceeds the outer end face of the post 102.
Preferably, the rigid top contact 12 is an insulating material to avoid electrical leakage to interfere with the heating circuit, and in this embodiment, the rigid top contact 12 is made of ceramic.
It should be noted that, in the conventional integrated hydraulic switch 10, the top-contacting component acting on the on-off switch 8 is also made of an elastic material, and therefore, the top-contacting component is easily deformed by pressure, so that the acting force on the on-off switch 8 is insufficient, and the on-off switch 8 cannot be started effectively in time. Even the top contact component can be skewed in the pressing and holding process, so that the start failure caused by the fact that the start-stop switch 8 cannot be accurately aligned, and the top contact component can be damaged in the repeated skew extrusion process.
In the hydraulic switch 10 provided in this embodiment, the rigid top contact element 12 and the convex post 102 are combined, so that the rigidity of the whole top contact element is improved, the hydraulic switch is not inclined, the front end surface of the rigid top contact element 12 can accurately move along a predetermined track, and sufficient acting force is provided to trigger the on-off switch 8.
Compared with the conventional split type water pressure switch 10 in the prior art, the water pressure switch 10 provided by the embodiment has better linkage performance, the rigid top contact piece 12 can move when the elastic cap 11 is under the action of water pressure, and the starting sensitivity of the switch can be further improved.
In addition, the rigid top contact piece 12 is arranged on the convex column 102 of the elastic cap 11, so that the effects of the rigid top contact piece 12 and the cap body 101 of the elastic cap 11 can be avoided, the probability of damage to the cap body 101 is reduced, and the maintenance cost is indirectly reduced.
Preferably, the bottom a and the peripheral side of the cap body 101 enclose a water collection chamber. The water in the heating water tank 6 enters the water collecting cavity and pushes the bottom a of the cap body 101 when certain water pressure is collected.
As shown in fig. 5 to 9, it is further preferable that the cap body 101 is provided with a thickened boss 15 at the inner end of the boss 102, the thickened boss 15 having a sectional diameter larger than that of the rigid top contact 12, the inner end face of the rigid top contact 12 falling into the thickened boss 15. This can further prevent the rigid contact piece 12 from cutting the cap body 101.
In another embodiment, the convex column may be a hollow structure, and the rigid contact member is sleeved in the convex column. Specifically, the middle of the convex column is provided with a groove with an outward opening, and the rigid abutting part is embedded in the groove of the convex column. The outer end face of the rigid push contact is a flat face, and the outer end face of the rigid push contact is flush with or exceeds the opening edge of the groove.
The water pressure switch and the electric heating faucet provided by the present invention are described in detail, and the principle and the embodiment of the present invention are explained in detail by using specific examples, and the description of the examples is only used to help understanding the present invention and the core idea. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
