Description
Technical Field
The invention belongs to the technical field of bathing devices, and relates to a mixing valve of a bathing device.
Background
Showering is one of the common ways of cleaning the body, and nowadays, people commonly use a shower head when taking a shower. The shower head is firstly opened to wet the body in the shower process, then the shower head is turned off to paint the shower gel on the body and rub the body, and finally the shower head is opened to wash the shower gel. The bathing mode needs to be carried out in three stages, the shower head is closed in the middle of the bathing mode, so that the temperature is reduced, and particularly in winter, the bathing experience is poor.
In order to improve the comfort and convenience of bathing, the chinese patent literature discloses a shower with bathing liquid [ application number: CN 201511002107.0; publication number: CN 105395115 a ], comprising a liquid inlet device, a bath bottle and a water diversion valve. The liquid inlet device is arranged on the shower rod and communicated with the shower waterway, and the shower bottle is arranged at the top of the liquid inlet device and communicated with the inner cavity of the liquid inlet device. The liquid inlet device comprises a liquid inlet shell, a fixed joint, a pull rod spring and an extrusion elastic sheet, wherein the liquid inlet shell is a three-way component and is provided with a horizontal inlet end, a horizontal outlet end and a vertical inlet end, and a liquid outlet hole is formed in the horizontal outlet end. The fixed joint is fixedly sleeved in a horizontal outlet end of the liquid inlet shell, the inner end of the pull rod is movably sleeved in a horizontal inlet end of the liquid inlet shell, a penetrating end of the pull rod is opposite to a through hole in the middle of the liquid inlet shell and can abut against the through hole, and the outer end of the pull rod is located outside the liquid inlet shell. The extrusion shrapnel is fixedly sleeved in the middle of the pull rod and is positioned below the vertical inlet end of the liquid inlet shell. Two ends of the pull rod spring are respectively connected to the penetrating end of the pull rod and the fixed joint. The shunt valve is arranged in the middle of the shower rod, and the liquid inlet device is arranged on the shunt valve and communicated with the inner cavity of the shunt valve.
When bathing, outside pulling pull rod makes the bathing liquid enter into the inboard of extrusion shell fragment, then releases the pull rod, makes the pull rod inwards move under the effect of pull rod spring, and the extrusion shell fragment is carried the bathing liquid to horizontal exit end department, then opens the water knockout drum, and water gets into and mixes with the bathing liquid from the play liquid hole of horizontal exit end, then mixes water and is carried the gondola water faucet blowout, and along with the lapse of shower time, it is replaced by clear water to mix water, washes totally again. However, since the bath liquid once entering the horizontal outlet end is a fixed value, when the mixed water is required to be continuously used, the pull rod needs to be pulled and pulled for many times in the bath process, the switching cannot be realized immediately when the clean water needs to be switched for washing, the mixed water can only be used up completely, once the pull rod is operated by mistake, the filling of the bath liquid cannot be cancelled, and the clean water can only be discharged after the mixed liquid of the bath liquid is sprayed, so that the use convenience of the shower is not enough.
Disclosure of Invention
The invention aims to solve the problems in the prior art, provides a mixing valve of a bathing device, and solves the technical problem that the existing bathing device is not convenient to use.
The purpose of the invention can be realized by the following technical scheme:
the utility model provides a mixing valve of shower device, includes valve body and case, water inlet channel and liquid outlet channel have been seted up to the valve body, its characterized in that, the case inserts in the valve body and can rotate, the case seted up the feed liquor hole and with feed liquor hole intercommunication and can produce the water negative pressure passageway of crossing of negative pressure to the feed liquor hole, still set up the inlet channel that can communicate relatively with the feed liquor hole on the valve body, rotate the case and can enough change the sectional area of intercommunication mouth between feed liquor hole and the inlet channel, can guarantee again that water inlet channel and liquid outlet channel remain the intercommunication through crossing water negative pressure passageway all the time.
Before use, the water inlet channel is communicated with a water pipe or a water valve, and the liquid inlet channel is communicated with a liquid storage barrel filled with shower gel. When the water inlet negative pressure channel is used, clean water is introduced into the water inlet channel, and flows out of the liquid outlet channel after passing through the water outlet negative pressure channel. When the valve core rotates to the point that the sectional area of a communication port between the liquid inlet channel and the liquid inlet hole is not zero, the liquid inlet hole is communicated with the liquid inlet channel, the water passing negative pressure channel generates a negative pressure effect when passing water, so that shower gel is automatically sucked into the water passing negative pressure channel through the liquid inlet channel and the liquid inlet hole to be mixed with clear water to form mixed liquid, and the mixed liquid is continuously foamed in the flowing process and continuously sprayed out from the liquid outlet channel in the form of foam.
The rotary valve core can change the sectional area of a communication port between the liquid inlet hole and the liquid inlet channel and can ensure that the water inlet channel and the liquid outlet channel are always communicated through the water passing negative pressure channel, on one hand, the flow of shower gel sucked into the water passing negative pressure channel can be adjusted through the rotary valve core to change the proportion of the shower gel in the mixed liquid, on the other hand, the communication state of the water passing negative pressure channel cannot be changed through the rotary valve core, and the water inlet channel and the liquid outlet channel are always communicated only through the water passing negative pressure channel, so that the water passing state of the water passing negative pressure channel cannot be influenced when the valve core is rotated, the negative pressure effect of the water passing negative pressure channel on the liquid inlet hole is always generated in the process of rotating the valve core, the shower gel can be automatically mixed into clear water when the flow is adjusted, a user can conveniently know the instant liquid outlet state, and can adjust the flow of the shower gel at any time according to needs, is convenient to use. When shower gel does not need to be doped into clear water, the valve core is rotated until the sectional area of the communication port between the liquid inlet channel and the liquid inlet hole is zero, so that the liquid inlet hole and the liquid inlet channel are not communicated any more, and the clear water can be sprayed out from the liquid outlet channel in real time. Therefore, in the bathing process, the sprayed liquid state can be changed instantly by rotating the valve core according to the requirement, and the use convenience of the bathing device is improved.
