Abstract

A flow switch device comprises a valve body (10) provided with a normally opened water flow channel and a normally closed water flow channel in the axial direction. A switching device (50) is arranged in the downstream direction perpendicular to the water flow and comprises a valve seat (52) provided perpendicular to the flow direction and a switching shaft (54) capable of sliding in the valve seat back and forth. The switching shaft has a large end and a small end. The small end is connected to a button (56) and extends out of the valve body, and the large end is abutted against an elastic member (58) mounted in the valve seat. In normal state, the elastic force of the elastic member acting on the switching shaft maintains the switching shaft in a first position, and the large end of the switching shaft blocks off the water flow in the normally closed water flow channel. When the button is pressed, the switching shaft is moved to a second position, thus the normally closed water flow channel is opened, the flow from the normally closed water flow channel passes through the large end and the small end of the switching shaft, and the pressure difference of the water flow between the large end and the small end overcomes the elastic force of the elastic member to maintain the switching shaft in the second position for the convenience of use.

具体实施方式detailed description
请参照图1，本发明的一种流量切换装置，具有节水、调整出水流量、断水后自动恢复小流量出水的优点。所述流量切换装置包括一阀体10、一节水片30、一切换装置50及一塞子70。Referring to FIG. 1 , a flow switching device according to the present invention has the advantages of saving water, adjusting the flow rate of the water, and automatically recovering the small flow of water after the water is cut off. The flow switching device includes a valve body 10, a water piece 30, a switching device 50 and a plug 70.
请参照图1至图3，该阀体10沿轴向设有一常开水流通道12和一常闭水流通道14。该节水片30置于该阀体10内并设置在水流的上游。该节水片30的中部设有一通孔32。Referring to FIGS. 1 to 3, the valve body 10 is provided with a normally open water flow passage 12 and a normally closed water flow passage 14 in the axial direction. The water-saving sheet 30 is placed in the valve body 10 and disposed upstream of the water flow. A through hole 32 is defined in the middle of the water saving piece 30.
该切换装置50设置在垂直该阀体10的水流的下游方向。该切换装置50包括一垂直水流方向设立的阀座52、一可在阀座52内往复滑动的切换轴54、一按钮56及一弹性件58。该阀座52与该阀体10一体成型。该阀座52的侧壁上设有一第一开口522和一第二开口524，该第一开口522与常闭水流通道14的水流的入口连通。该第二开口524与常闭水流通道14的水流的出口连通。该阀座52的侧壁向外延设有一连接通道526，该第一开口522位于该连接通道526内，该连接通道526连接该第一开口522与通孔32。所述的切换轴54具有一大端544和一小端542。该第二开口524位于该大端544与该小端542之间。该小端542连接该按钮56并向上伸出阀体10外。该塞子70连接在该阀座52的底部。该弹性件58设于阀座52内，该弹性件58弹顶在该塞子70与该大端544之间。The switching device 50 is disposed in a downstream direction of the water flow perpendicular to the valve body 10. The switching device 50 includes a valve seat 52 defined by a vertical flow direction, a switching shaft 54 reciprocally slidable within the valve seat 52, a button 56 and an elastic member 58. The valve seat 52 is integrally formed with the valve body 10. A sidewall 522 and a second opening 524 are formed in the sidewall of the valve seat 52. The first opening 522 is in communication with the inlet of the water flow of the normally closed water flow passage 14. The second opening 524 is in communication with the outlet of the water flow of the normally closed water flow passage 14. A connecting passage 526 is defined in the sidewall of the valve seat 52. The first opening 522 is located in the connecting passage 526. The connecting passage 526 connects the first opening 522 and the through hole 32. The switching shaft 54 has a large end 544 and a small end 542. The second opening 524 is located between the large end 544 and the small end 542. The small end 542 connects the button 56 and projects upwardly out of the valve body 10. The plug 70 is attached to the bottom of the valve seat 52. The elastic member 58 is disposed in the valve seat 52, and the elastic member 58 is spring-mounted between the plug 70 and the large end 544.
该阀座52为阶梯筒状结构，包括大筒部521和小筒部523，大筒部521、小筒部523的内径分别与切换轴54大端544、小端542的外径相适配；第一开口522开设在大筒部521的侧壁上，与常闭水流通道14的水流的入口连通；第二开口524开设在小筒部523的侧壁上，与常闭水流通道14的水流的出口连通。The valve seat 52 has a stepped cylindrical structure, and includes a large tubular portion 521 and a small tubular portion 523. The inner diameters of the large tubular portion 521 and the small tubular portion 523 are respectively adapted to the outer diameters of the large end 544 of the switching shaft 54 and the small end 542; An opening 522 is formed in the side wall of the large cylindrical portion 521 to communicate with the inlet of the water flow of the normally closed water flow passage 14; the second opening 524 is opened on the side wall of the small cylindrical portion 523 and the outlet of the water flow of the normally closed water flow passage 14. Connected.
阀座52的侧壁向外延设的连接通道526位于大筒部521和小筒部523的结合部；第一开口522位于该连接通道526内。The connecting passage 526 of the sidewall of the valve seat 52 to the extension is located at a joint portion of the large tubular portion 521 and the small tubular portion 523; the first opening 522 is located in the connecting passage 526.
连接通道526与阀体10的主体11同轴设置，界定位于连接通道526内的常闭水流通道14，连接通道526与主体11之间的常开水流通道12。阀座52和主体11可一体成型，使得产品整体结构更为紧凑。The connecting passage 526 is disposed coaxially with the body 11 of the valve body 10, defining a normally closed water flow passage 14 in the connecting passage 526, and connecting the normally open water flow passage 12 between the passage 526 and the main body 11. The valve seat 52 and the body 11 can be integrally formed, so that the overall structure of the product is more compact.
自然状态时，弹性件58对切换轴54的弹力使切换轴54向上移动并保持在第一位置。此时，切换轴54大端544的上端面抵靠在阀座52的阶梯面，使得大端544封堵所述第一开口522，阻断常闭水流通道14的水流，水流仅能从常开的水流通道12通过。In the natural state, the elastic force of the elastic member 58 on the switching shaft 54 causes the switching shaft 54 to move upward and remain in the first position. At this time, the upper end surface of the large end 544 of the switching shaft 54 abuts against the step surface of the valve seat 52, so that the large end 544 blocks the first opening 522, blocks the water flow of the normally closed water flow passage 14, and the water flow can only be abnormal. The open water flow passage 12 passes.
当向下触压按钮56时，切换轴54向下移动至第二位置，常闭水流通道14打开，即该大端544开启该第一开口522，来自常闭水流通道14的水从切换轴54的大端和小端之间通过。此时，由于大端544上端面面积大于小端542下端面面积，其压差克服弹性件58的弹力使切换轴54在第二位置的状态得以保持，水流同时从常开的水流通道12和常闭的水流通道14通过。不需要人为长时间按压该铵钮，操作方便。When the button 56 is pressed down, the switching shaft 54 moves downward to the second position, and the normally closed water flow passage 14 is opened, that is, the large end 544 opens the first opening 522, and the water from the normally closed water flow passage 14 is switched from the switching shaft. Pass between the big end and the small end of 54. At this time, since the upper end surface area of the large end 544 is larger than the lower end surface area of the small end 542, the pressure difference overcomes the elastic force of the elastic member 58 to maintain the state of the switching shaft 54 in the second position, and the water flow simultaneously from the normally open water flow passage 12 and The normally closed water flow passage 14 passes. It is not necessary to manually press the ammonium button for a long time, and the operation is convenient.
可以理解地，在断水后，该弹性件58的作用力使该切换轴54重新上移至第一位置，关闭该常闭水流通道14。使得每次在通水使用的时候，该流量切换装置都处在小流量状态，具有强制节水的优点。It can be understood that, after the water is cut off, the force of the elastic member 58 causes the switching shaft 54 to be moved up to the first position to close the normally closed water flow passage 14. The flow switching device is in a small flow state each time the water is used, and has the advantage of forced water saving.
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。The above is only the preferred embodiment of the present invention, and thus the scope of the present invention is not limited thereto, that is, equivalent changes and modifications made in accordance with the scope of the invention and the contents of the specification should still be covered by the present invention. Within the scope.
