Abstract

The invention belongs to the technical field of valves with locking caps or locking rods, and relates to an anti-scalding faucet. The anti-scalding faucet comprises a water inlet pipe and a water outlet pipe which are integrally formed. A valve cavity is formed in the communicating position of the water inlet pipe and the water outlet pipe. A rubber plug capable of moving vertically is arranged in the valve cavity. A gland is arranged above the valve cavity. A transmission shaft penetrates through the gland and then is connected with the rubber plug. The upper end of the transmission shaft protrudes outwards to form a pressing plate. A cam is arranged between the pressing plate and the top face of the gland and is in key joint with a rotating handle. Hot water can flow out only through a precise rotating angle, operation difficulty is higher, and the situation that the faucet is touched by mistake to be opened cannot happen easily.

Existing water purifier is primarily of formations such as shell, filter core, heating chambers, filter core is positioned at shell, intake pipe is connected with shell, and normal temperature water pipe is connected with filter core inner chamber and releases normal-temperature water by normal-temperature water switch, and heating chamber is also connected with filter core inner chamber and releases heating water by hot-water switch.Existing hot-water switch is generally Pushtype water tap, the outlet part comprising inlet part and communicate with inlet part, inlet part and the outlet part position that communicates is blocked by plug, and this plug is connected with transmission shaft, transmission shaft move up and down the opening and closing controlling plug.Moving up and down of transmission shaft is controlled by pressing handle: be specially the spring be provided with between transmission shaft and plug, the lower end of spring props up plug, the upper end of spring props up the gland of Pushtype water tap, the part that transmission shaft stretches into gland is rotationally connected with handle, with the balance pivot that can be supported on gland on handle, when pressing handle, then drive on rotatingshaft and move, thus hot water is flowed out, otherwise unclamp pressing handle, then plug moves down under the action of the spring, blocking channel, hot water stops flowing.

The shortcoming of such scheme is: the family some being had to child, and the design of Pushtype water tap is very simple, easily presses down pressing handle because of carelessness, cause hot water to flow out, cause scald when child is at play.

Summary of the invention

The invention is intended to provide a kind of avoid because pressure causes hot water to flow out the anti-scald water tap causing scald by mistake.

Anti-scald water tap in this programme, comprise integrated intake pipe, outlet pipe, intake pipe and the outlet pipe place of communicating form valve pocket, plug moving up and down is provided with in this valve pocket, be gland above valve pocket, transmission shaft is connected with plug after running through gland again, and described passing shaft upper end evagination forms pressing plate, be provided with cam between this pressing plate and gland end face, this cam is connected with handle with sleeve key.

Beneficial effect: transmission shaft moves plug can be driven to open valve pocket, in this programme, cam is set at the pressing plate of transmission shaft and gland end face, when the cam of cam contacts with pressing plate or the convex surface of cam contacts with gland (when the convex surface of cam is positioned at vertical direction), can promote pressing plate, transmission shaft move, plug is opened, compare the situation that traditional Pushtype water tap easily touches out hot water by mistake, the present invention needs the rotation angle of precision that hot water just can be made to flow out, and is less likely to occur to touch leading situation of fetching boiling water by mistake.

Further, handle with sleeve comprises the counterweight handle of horizon bar, horizon bar coordinates with the holder pivots that gland is arranged, support is as the installation position of handle with sleeve, the axis of counterweight handle and the axis of cam convex surface stagger mutually, make operator unclamp handle with sleeve, configuration handle when naturally drooping like this, the convex surface of cam does not contact with gland or pressing plate, plug closeding valve cavity.

Further, with inner cap group inside gland, between inside this inner cap group and gland, leave gap, for carrying out spacing to plug upper end.

Further, this plug is the cylindrical structural that upper end is large, lower end is little, and the diameter of plug lower end is greater than the caliber of outlet pipe, and plug lower end is used for closing outlet pipe, and plug inside has blind hole from top to bottom.This plug has elasticity, good sealing effect.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment of the present invention anti-scald water tap.

Embodiment

Below by embodiment, the present invention is further detailed explanation:

Reference character in Figure of description comprises: intake pipe 1, outlet pipe 2, plug 3, gland 4, inner cap group 41, blind hole 5, limiting stopper 6, transmission shaft 7, spring supporting platform 71, return spring 8, pressing plate 9, cam 10, handle with sleeve 11.

Embodiment is substantially as shown in Figure 1: anti-scald water tap, comprises the intake pipe 1 of level, vertical outlet pipe 2, and intake pipe 1 and the one-body molded and pipeline of outlet pipe 2 communicate, and its place of communicating forms the valve pocket holding plug 3.

The upper end of this valve pocket is gland 4, and this gland 4 screw thread is tightened on the outer wall of outlet pipe 2 upper end, with the inner cap group 41 of annular inside this gland 4, leaves gap between inside this inner cap group 41 and gland 4.Plug 3 is the cylindrical structural that upper end is large, lower end is little, and the diameter of plug 3 lower end is greater than the caliber of outlet pipe 2, and plug 3 inside has blind hole 5 from top to bottom, and the upper end of plug 3 contacts with gland 4 and in gap between gland 4 and inner cap group 41.

The blind hole 5 of plug 3 is made up of three parts, is divided into rod aperture portion, neck bore portion and spacing hole portion from top to bottom successively, and their pore size is rod aperture portion > spacing hole portion > neck bore portion.Be placed with limiting stopper 6 in neck bore portion, transmission shaft 7 runs through gland 4 and its lower end is threaded with limiting stopper 6.This transmission shaft 7 bottom is with spring supporting platform 71, and spring supporting platform 71 is positioned at rod aperture portion, insertion rod on the downside of spring supporting platform 71 and gland 4 between cover have return spring 8.

The upper end evagination of transmission shaft 7 forms pressing plate 9, and be furnished with cam 10 between this pressing plate 9 and gland 4, the axle center of this cam 10 is connected with handle with sleeve 11 by flat key.This handle with sleeve 11 comprises horizon bar and is welded on the counterweight handle of horizon bar end, the horizon bar of this handle with sleeve 11 coordinates with the holder pivots on gland 4, the counterweight handle of handle with sleeve 11 and the convex surface of cam 10 are not located along the same line, and namely the axis of counterweight handle and the axis of cam 10 convex surface stagger mutually.
