Shower equipment with adjustable jet flow

Abstract

The invention discloses shower equipment with adjustable jet flow. A spraying needle is arranged in a spraying nozzle. A cold water inflowing space and a jet flow cold water outlet are formed between the spraying nozzle and the spraying needle. A hot water inflowing space is formed between the spraying nozzle and a valve body. A cold water inlet is respectively communicated with a cold water opening and the cold water inflowing space. A hot water inlet is respectively communicated with a hot water opening and the hot water inflowing space. When the shower equipment is used, the cold water inflowing space, the hot water inflowing space and the jet flow cold water outlet can be adjusted as long as the spraying nozzle is adjusted to move in the axis direction of a jet flow injection valve. According to the technical scheme, the good injection effect is achieved through a simple operation mode.

Description

technical field [0001] 本发明涉及一种射流混液器,尤其涉及一种应用于太阳能热水器供水系统中的射流混液器,属于太阳能热水器技术领域。 Background technique [0002] 现有太阳能热水器主要包括承压式和非承压式。 [0003] 承压式太阳能热水器的工作原理是:自来水经控制开关进入水箱和热管,集热管吸收太阳辐射后通过介质将热能传递给热管中的冷水,循环加热水箱中的水,由于水箱是整体封闭结构,使用时必需打开冷水进水口,用自来水的水压顶出水箱中的热水,使热水从出水口流入到用水单元。此种结构的水箱承受自来水的压力,出水流量相对较大,使用舒适度较好,但是,该种结构的水箱需要承受7MPa的水压,内部还需增加热管结构,对密封性要求较高,材料较厚,从而导致热水器的成本较高。 [0004] 非承压式太阳能热水器的工作原理是:自来水经控制开关连接到水箱的进出水口(挡水板),直至充满水箱和玻璃热管,玻璃热管吸收太阳光后加热水箱与玻璃热管中的水,水箱中的水被加热后再通过进出水口流到室内用水单元供用户使用。此种结构的水箱与玻璃热管只承受水箱高度的水压,受压较小,因此,玻璃热管与水箱不需要耐压设计,节约材料,相对于承压式太阳能热水器来说成本较低。但是,该种结构的太阳能热水器,由于水箱的安装高度受限于建筑结构,一般很难提供较高水压给出水单元,造成出水单元的出水流量较小,影响使用舒适度。 [0005] 中国专利文献CN103016421A公开了一种射流器及具有该射流器的热水器阀门,属于非承压式热水器阀门,其通过设置合理的射流增压结构,同时达到了射流增压与降低成本的作用。然而,该文献公开的热水器阀门,其喷嘴的口径是固定不变的,在通过冷、热水流量调节开关分别调整冷、热水的进水流量时,当冷水调节开关的开口小于喷口的口径时,喷嘴内的工作液的水压将被降低,从而使得冷水工作液的喷射速度降低,其抽吸热水的效果不好,从而导致夏天使用时舒适度不高。 [0006] 中国专利文献CN102086941B公开了一种混水阀门,包括阀体,所述阀体上设置有阀体冷水进口、阀体热水进口、阀体出水口以及与阀体冷水进口相连的喷嘴,所述喷嘴上设有喷嘴冷水进口和喷嘴冷水出口,所述阀体内还设有与所述阀体热水进口相连的热水调节腔以及与所述阀体出水口相连的混水腔...

AI Technical Summary

Problems solved by technology

[0007] When the nozzle is rotated, the needle valve and the nozzle move together. During this process, the nozzle and the needle valve do not move relative to each other, so that the cross-sectional area of ​​the cold water outlet remains constant. In this way, when the cross-sectional area of ​​the cold water inlet is smaller than that of the cold water outlet When the cross-sectional area is small, the water pressure of the cold water in the nozzle will be very small, and it is difficult to achieve a good spray effect. In order to ensure a good spray effect, it is necessary to adjust the needle valve at the same time, thereby reducing the cross-sectional area of ​​the cold water outlet, and then requiring Simultaneous adjustment of the needle valve and nozzle increases the difficulty of use, and if the needle valve and nozzle are not adjusted at the same time, it will be difficult to ensure a better water discharge effect and higher use comfort
