Abstract

The utility model discloses a pedal shower, which is characterized in that the shower can be bridged onto a feed line without any pipe joint directly, a sleeve-shaped sealing plug fixed with a valve rod is arranged in a valve, and the water outlet is sealed in the mode of down streams; the pedal mechanism is composed of a pedal plate and a lever which are lapped with each other; the installation of the shower is free from the restriction of a wall corner; a papillary veneer is stuck on the pedal plate. Effluent water can get into a stationary nozzle by a reversing three-way, and can also get into a hand-hold spray head. The pedal shower is suitable for a collective and public bathhouse.

Description

Pedal bathing douche

The utility model belongs to a kind of hot-water heating utensil with foot-operated action control shower water.It is applicable to places such as collective bathroom.

In prior art, shower person is with hand control valve feedwater or cuts off the water because people's both hands when shower are in running order, when temporarily do not need water towards the time, be not easy in time close water, but avoid the trickle district, cause the waste of water.In recent years, be using water wisely, domestic some showers of having released with foot-operated action control shower water, the bather is by-pass valve control with the hands, and the people then cuts off the water immediately from footstep mechanism.Existing patented product number is: 86201787.4; 86210191.3; 91202478.x etc.The shortcoming of these products is and need just can be contained on the feed pipe by pipe fittings such as threeways.Because this valve has adopted and flows seal form against the current, for reaching sealing purpose, the pressure of having to add big spring overcomes the static pressure of water.When the needs Open valve,, cause the damage of supply line and shower easily because valve member is stressed excessive.In addition, the relative motion between valve rod and the valve body is by the sealing of " O " shape sealing ring, because the wearing and tearing of sealing ring cause leaking easily.Spring and valve rod also because of long-term corrosion under water, cause defective valve or damage.Moreover its pedal is a long arm lever structure, and fulcrum is in the end, and hold-down screw must be installed near the foot of a wall, implements relatively difficulty.Pedal is out of shape greatly or fractures because of stressed.

The purpose of this utility model is to release the Water-saving shower device tool of a kind of easy for installation, good airproof performance, firm and durable.

Feature of the present utility model be constitute have on the valve body of valve two with the direct-connected interface of feed pipe; Footstep mechanism is by the lever and the pedal of overlap joint are formed mutually; Be provided with the sealing-plug that a bottom is shell-like in the valve, and female it be pressed on the valve body by compressing, be sealed on the valve port in stream mode downstream, valve rod and spring are mounted in it, and an end and the sealing-plug of valve rod are consolidated, and valve rod is not contacted with water with spring; Be stained with the flexible veneer of papillary of anti-skidding and health-care effect on the pedal; The top of valve body is provided with the commutation threeway, and two delivery port joins with trickle shower nozzle and hand-held shower respectively.

Structure of the present utility model as shown in the figure.It is made up of valve and footstep mechanism and chain rope, shower nozzle (figure slightly) etc.Valve is by commutation threeway 1, sealing-plug 2, guide pipe 3, valve body 4, spring 5, valve rod 6 and compress female 7 and form; Footstep mechanism is made up of parts such as lever 10 and pedal 11, rubber veneer 13, fixed pivot 12 and chain rope 8, regulating parts 9.

Valve body 4 is that it that manufacture with malleable cast iron or non-ferrous metal has A, B, four interfaces of C, D, and shape is similar to the pipe fitting four-way.Delivery port D is located at the top of valve body, and the A mouth of below is the export mouth of valve rod 5.The B of valve body both sides, C interface diameter are Dg20～Dg50mm, do not need other pipe fittings during installation and directly are connected across on the supply line, form row's shower as required, and the valve of last shower can be shut with pipe fitting or joint door.Sealing-plug 2 usefulness flexible materials are made, and it seals valve port E in stream mode downstream, and the bottom of sealing-plug is cannula-like, and its end is a loop sealing ring of digging, and with clamp nut it is pressed on the valve body, the effect of play sealing, isolating.Start to control the valve rod 6 of making usefulness and spring 5 and all be located at the inside of sealing-plug 2, and an end of valve rod and sealing-plug 2 be consolidated, the other end of valve rod is drawn by the centre bore of the clamp nut 7 of valve body lower portion, joins with chain rope 8.Therefore, spring, valve rod and water are isolated fully.And, because the sealing-plug bottom is one section flexible sleeve, no longer need slipper seal between valve rod and the valve body, overcome the seepy question of prior art.Be provided with commutation threeway 1 on the top of valve body 3, it has F and two delivery ports of G, and the standpipe of G and shower nozzle joins, and F and hand-held shower join, and can pass through manual reverse of direction.Guide pipe 3 is fixed on the delivery port D place of valve body 4 with thread connecting mode, and its inside is provided with the valve port E that diameter is 5～15mm, and its side is provided with the discharge orifice.

Footstep mechanism rigid material of the present utility model, it is made of lever 10, pedal 11 and fixed pivot 12,

part

10 and 11 both overlap mutually, the regulating part 9 that tensioner is used is housed on the chain rope.When pedal moved downward, the also downward tractive of chain rope 8 reached out the valve purpose.Because the position of footstep mechanism fixed pivot is placed in the middle, not restricted by the corner.For anti-skidding, anti-corrosion, increase spread effect to the sole acupuncture point, on pedal 11, be stained with the flexible veneer 13 of papillary.

Embodiment:

Valve body 4 of the present utility model is cylinder iron made, and the diameter of interface B and C is the gas thread of Dg40mm, and the diameter of A and D is the gas thread of Dg20mm.The external pipe thread of guide pipe is Dg20mm, and guide pipe length is 15mm, and its internal diameter is 18mm, and the diameter of valve port E is 12mm, and the guide pipe both sides have the discharge orifice of two 50mm.Sealing-plug height 60mm, external diameter 16mm, internal diameter 13mm is with 50～60 degree butyronitrile rubber manufacturings.Pedal is wide fan-shaped of 200mm, and the top is stained with the high papillary rubber veneer of 5mm, and the total length after lever and the pedal assembling is 350mm.

This control of product is flexible, laborsaving, and is water-tight, easy for installation.
