[0039] The method of using the utility model is as follows:
[0040] The hose connector 4 can be used to directly connect the hose, and the hose is used to transport ordinary water flow, and the clean water connector 18 can be used to directly connect the clean water pipeline, and the clean water pipeline can transport the incoming water, and the clean water pipeline can be hidden in the hose, and the ordinary water flow can flow through the gap between the outer wall of the screw connector 3 and the inner wall of the hose.
[0041] When the clean water in the clean water pipeline enters the docking joint 25 through the clean water joint 18, it will directly flow into the left switching hole 8. The position where the docking joint 25 and the left switching hole 8 intersect is lower than the lower end port of the left sleeve 26, and the lower end port of the left sleeve 26 is blocked and sealed by the outer edge of the first sealing ring 35. Therefore, the clean water cannot continue to flow. When clean water is needed, the lower end port of the left sleeve 26 can be opened by pressing the clean water button 12 downward. When the clean water button 12 is pressed downward, the pressing structure has the effect of changing the upper and lower positions of the opening and closing member 32. The pressing structure is actually the same as the pressing structure used in the existing push-type ballpoint pen. When the left pressure rod 11 moves downward under the pressure of the clean water button 12, the triangular head 39 moves downward along the trajectory of the guide groove 40. At this time, the triangular head 39 will squeeze the inclined surface of the upper end of the bevel tooth 45, thereby causing the push rod 42 to move downward. When the push rod 42 moves downward, the push rod 42 will pass through the groove on the boss 33 44 pushes the opening and closing member 32 downward to achieve the downward movement of the opening and closing member 32. In the existing pressing structure, each guide groove 40 is provided with a corresponding inclined guide surface to transitionally connect the lower ends of adjacent guide grooves 40 together, and the adjacent guide grooves 40 can be divided into complete guide grooves and incomplete guide grooves. When the triangular head 39 at the lower end of the left pressure rod 11 pushes the bevel tooth 45 downward out of the complete guide groove, the first spring 37 will apply its own elasticity to the push rod 42 through the opening and closing member 32. Under the guiding action of the inclined surface at the upper end of the bevel tooth 45, the push rod 42 will rotate, and the bevel tooth 45 will slide into the incomplete guide groove along the guide surface between the complete guide groove and the incomplete guide groove. At this time, the position of the opening and closing member 32 after the downward movement is fixed. If the opening and closing member 32 needs to be moved up and reset to block and seal the lower end port of the left sleeve 26 again, it is only necessary to press the water purification button 12 downward once more, so as to form an opening and closing cycle, which is consistent with the effect of the refill of a push-type ballpoint pen popping out and retracting.
[0042] When the opening and closing member 32 is moved down and fixed, the lower end port of the left sleeve 26 is opened, and the clean water will flow into the left sleeve 26 through the lower end port of the left sleeve 26, and then will flow into the first water groove 28 through the first water hole 27 and the first connecting hole 30 in sequence, and then flow into the clean water channel 20 through the second connecting hole 31, and finally be sprayed out from the clean water hole 19 for use.
[0043] When the clean water connector 18 is connected to the clean water pipeline, after the ordinary water in the hose enters the hose connector 4, the ordinary water will pass through the gap between the inner wall of the screw connector 3 and the outer wall of the clean water connector 18, and then pass through the gap between the adjacent connecting rods 24 to enter the third connecting hole 68, and then enter the second water groove 66. Under the push of the subsequent water flow, the ordinary water will flow into the middle switching hole 9 through the fourth connecting hole 69. When the lower end port of the middle sleeve 52 is blocked and sealed by the second sealing ring 55, the ordinary water entering the middle switching hole 9 can only flow into the third water groove 70 through the middle switching groove 57 and the fifth connecting hole 72 in turn. The ordinary water entering the third water groove 70 will flow into the right switching hole 10 through the sixth connecting hole 73. When it is needed, To use shower water, the right end of the long button 14 can be pressed downward to make the right end of the long button 14 swing downward. At this time, the right end of the long button 14 will press down the right pressure rod 17 to move the right pressure rod 17 downward, thereby realizing the downward movement of the right opening and closing head 81. When the right opening and closing head 81 moves downward with the third sealing ring 83, the lower end port of the right sleeve 79 is in an open state, and the upper notch of the right switching groove 74 is blocked and sealed by the outer edge of the third sealing ring 83. At this time, ordinary water entering the right switching hole 10 can only enter the right sleeve 79 through the lower end port of the right sleeve 79, and then flow into the fourth water groove 92 through the third water hole 80 and the seventh connecting hole 94 in turn, and then flow into the inside of the shower head 5 through the eighth connecting hole 95, and finally spray out through the water spray hole 7 on the shower cover 6 to form shower water for use.
[0044] When the terminal for controlling the flow rate of ordinary water is not turned on, the shower cannot spray water no matter how it is switched. When the terminal is turned on and the water purification button 12 and the long button 14 are not pressed, another water outlet mode will be formed. When the water purification button 12 and the long button 14 are not pressed, the ordinary water entering the middle switching hole 9 can only flow downward into the middle switching groove 57, and the ordinary water entering the right switching hole 10 can only flow downward into the right switching groove 74, and the ordinary water flows into the second water outlet through the gap between the inner wall of the screw joint 3 and the outer wall of the water purification joint 18. In the groove 66, ordinary water will enter the right switching groove 74 through the fourth connecting hole 69, the middle switching groove 57, the fifth connecting hole 72, the third water groove 70, and the sixth connecting hole 73 in sequence, and then enter the bubble water joint 75 through the water outlet channel 78, and finally be sprayed out through the bubbler 77 to form bubble water for use. The bubbler 77 is an existing bubbler that can fully mix the flowing water and air. With the addition of air, not only the flushing force of the water can be improved, but also the water flow is soft and comfortable like mist, which effectively avoids the water splashing everywhere and has a splash-proof effect.
[0045] When it is necessary to use blade water with high impact force, it can be achieved by pressing the left end of the long button 14 downward. First, ordinary water flows into the second water groove 66 through the gap between the inner wall of the screw joint 3 and the outer wall of the clean water joint 18, and then the ordinary water flows into the middle switching hole 9 through the fourth connecting hole 69. As the left end of the long button 14 swings downward, the middle pressure rod 16 drives the middle opening and closing head 53 to move downward. At this time, the middle opening and closing head 53 moves downward with the second sealing ring 55, and the second sealing ring 55 no longer blocks and seals the lower end port of the middle sleeve 52. When the ring 55 moves downward, the outer edge of the second sealing ring 55 will block and seal the upper notch of the middle switching groove 57. At this time, ordinary water entering the middle switching hole 9 can only enter the middle sleeve 52 through the lower end port of the middle sleeve 52, and then flow into the fifth water groove 96 through the second water hole 60 and the ninth connecting hole 98 in turn, and then flow into the blade water joint 99 through the water inlet channel 104, and then pass through the water inlet hole 102, and finally be rectified and sprayed out through the blade hole 103 to form a blade-shaped high-pressure water flow for use to ensure the cleaning quality.
[0046] To sum up, it can be known that the utility model can not only control the use of purified water through the purified water switching device, but also control the ordinary water to be sprayed out from the water spray hole on the shower head cover through the shower head switching device to form a conventional shower water mode, and can also switch the blade water outlet mode and the bubble water outlet mode through the middle switching device, so that the shower head has four water outlet modes at the same time, which can meet the different water needs of users. There is no need to replace different models of shower heads when using different water outlet modes, which reduces the trouble during use and can effectively reduce the cost of use.
