进一步的,感温元件25为现有技术,例如在公告号为CN209246207U的中国专利中已经公开,在此不进行详细赘述。Further, the temperature sensing element 25 is in the prior art, for example, it has been disclosed in the Chinese Patent Publication No. CN209246207U, which will not be described in detail here.

具体工作过程如下:The specific working process is as follows:

当太阳能热水进水组件3所流出的为热水时,感温元件25受热出现内部膨胀,进而导致轴向伸长。由于感温元件25的一端抵接第一弹簧15,且感温元件25的另一端通过分流垫26与截流壳18相抵,而截流壳18的一端又与第二弹簧24相抵。随着感温元件25受热伸长,进而使其一端对第一弹簧15进行施力,此时第一弹簧15受外力压缩。此外,由于第一弹簧15的劲度系数大于第二弹簧24的劲度系数,第二弹簧24相较于第一弹簧15更易被压缩,使得感温元件25将带动分流垫26以及截流壳18朝向第二弹簧24的方向进行运动,此时间隙14与阀芯组件5处于导通状态,太阳能热水进水组件3所流出的热水依次通过第二功能孔13、间隙14与阀芯组件5相导通。在该状态下,位于截流壳18外壁上的第一密封圈22以及第二密封圈22均第二功能孔13的内壁密封抵接。使得燃气热水器进水孔10所流出的热水均可被第一密封槽19、第二密封槽21内的密封圈22所阻隔,以实现对燃气热水器进水孔10的封堵。When the hot water flows out of the solar hot water water inlet assembly 3, the temperature sensing element 25 is heated and undergoes internal expansion, thereby causing axial elongation. One end of the temperature sensing element 25 abuts against the first spring 15 , and the other end of the temperature sensing element 25 abuts against the shut-off casing 18 through the diverter pad 26 , and one end of the shut-off casing 18 abuts against the second spring 24 . As the temperature sensing element 25 is heated and elongated, one end of the temperature sensing element 25 exerts a force on the first spring 15 , and at this time, the first spring 15 is compressed by an external force. In addition, because the stiffness coefficient of the first spring 15 is greater than that of the second spring 24 , the second spring 24 is more easily compressed than the first spring 15 , so that the temperature sensing element 25 will drive the shunt pad 26 and the shut-off shell 18 Move toward the direction of the second spring 24, at this time, the gap 14 and the valve core assembly 5 are in a conductive state, and the hot water flowing out of the solar hot water inlet assembly 3 passes through the second functional hole 13, the gap 14 and the valve core assembly in turn. 5-phase conduction. In this state, the first sealing ring 22 and the second sealing ring 22 located on the outer wall of the shut-off casing 18 are in sealing contact with the inner wall of the second functional hole 13 . The hot water flowing out of the water inlet hole 10 of the gas water heater can be blocked by the sealing ring 22 in the first sealing groove 19 and the second sealing groove 21, so as to realize the blocking of the water inlet hole 10 of the gas water heater.

当太阳能热水进水组件3所流出的水温逐渐降低至常温时,感温元件25将逐渐缩短至初始长度,该初始长度为感温元件25在冷水状态下的固定自然长度,其缩短复原的过程与上述伸长的过程相反,在此不加以详细赘述。When the temperature of the water flowing out of the solar hot water inlet assembly 3 is gradually reduced to normal temperature, the temperature sensing element 25 will gradually shorten to the initial length, which is the fixed natural length of the temperature sensing element 25 in the cold water state, which shortens the restored length. The process is opposite to the above-mentioned elongation process, and will not be described in detail here.

当感温元件25复原至固定长度时,截流壳18在第二弹簧24的驱动下切断间隙14与阀芯组件5之间的连通。由于截流壳18的运动,会带动位于其外圈第一密封槽19、第二密封槽21内的密封圈22同步运动。当截流壳18切断间隙14与阀芯组件5之间的连通时,位于第一密封槽19内的密封圈22脱离与第二功能孔13之间的配合,并与第二功能孔13之间间隔一定距离,此时燃气热水器进水孔10通过连通槽20与间隙14相连通,完成燃气热水器的进水。When the temperature sensing element 25 is restored to a fixed length, the shut-off shell 18 cuts off the communication between the gap 14 and the valve core assembly 5 under the driving of the second spring 24 . Due to the movement of the shut-off casing 18 , the sealing ring 22 located in the first sealing groove 19 and the second sealing groove 21 of the outer ring of the shut-off casing 18 is driven to move synchronously. When the shut-off shell 18 cuts off the communication between the gap 14 and the valve core assembly 5 , the sealing ring 22 located in the first sealing groove 19 is disengaged from the cooperation with the second functional hole 13 , and the sealing ring 22 is separated from the second functional hole 13 . At a certain distance, the water inlet hole 10 of the gas water heater is communicated with the gap 14 through the communication groove 20 to complete the water inlet of the gas water heater.

进一步的,支撑件16包括有与第一功能孔12螺纹连接的固定套28,固定套28朝向截流壳18的一端设置有可与截流壳18密封配合的封流面29。固定套28内置有可调内芯30,可调内芯30与固定套28螺纹连接。固定套28的一侧贯穿设置有可与内六角扳手相配合的内六角通孔31,可调内芯30朝向内六角通孔31的一侧设置有可与螺丝刀相配合的调节位32。第一弹簧15位于可调内芯30的内部,且第一弹簧15的一端与可调内芯30的内壁相抵接。Further, the support member 16 includes a fixing sleeve 28 threadedly connected with the first functional hole 12 , and one end of the fixing sleeve 28 facing the shut-off casing 18 is provided with a flow-sealing surface 29 that can be sealingly matched with the shut-off casing 18 . The fixed sleeve 28 has a built-in adjustable inner core 30 , and the adjustable inner core 30 is threadedly connected with the fixed sleeve 28 . One side of the fixed sleeve 28 is provided with an inner hexagonal through hole 31 that can be matched with an inner hexagonal wrench, and the side of the adjustable inner core 30 facing the inner hexagonal through hole 31 is provided with an adjustment position 32 that can be matched with a screwdriver. The first spring 15 is located inside the adjustable inner core 30 , and one end of the first spring 15 is in contact with the inner wall of the adjustable inner core 30 .

在实际使用时,操作者可通过内六角扳手将固定套28装配于第一功能孔12上。且可通过螺丝刀穿过内六角通孔31与可调内芯30上的调节位32相配合,以调整可调内芯30于固定套28内的不同深度,进而调整第一弹簧15的位置以改变其压缩量。In actual use, the operator can assemble the fixing sleeve 28 on the first functional hole 12 by using an Allen wrench. And the screwdriver can be passed through the hexagonal through hole 31 and matched with the adjustment position 32 on the adjustable inner core 30 to adjust the different depths of the adjustable inner core 30 in the fixed sleeve 28, and then adjust the position of the first spring 15 to Change its compression.

进一步的,所述第一弹簧15与感温元件25之间设置有垫片17,可调内芯30所远离调节位32的一端内壁上开设有卡槽33,卡槽33内设置有用以对垫片17进行限位的卡簧34。此外,由于卡簧34的中部为镂空状设置,使得感温元件25的一端可穿过卡簧34对垫片17进行抵接。通过卡簧34的设置,使垫片17无法在第一弹簧15弹力作用下而被顶出可调内芯30外,但垫片17可在感温元件25作用下向内压缩第一弹簧15。Further, a gasket 17 is arranged between the first spring 15 and the temperature sensing element 25, and a card slot 33 is formed on the inner wall of one end of the adjustable inner core 30 away from the adjustment position 32. The circlip 34 for the spacer 17 to limit the position. In addition, since the middle portion of the retaining spring 34 is hollow, one end of the temperature sensing element 25 can pass through the retaining spring 34 to abut the gasket 17 . Through the setting of the retaining spring 34 , the gasket 17 cannot be pushed out of the adjustable inner core 30 under the elastic force of the first spring 15 , but the gasket 17 can compress the first spring 15 inwardly under the action of the temperature sensing element 25 . .

需说明的是:感温元件25在无受热伸长的情况下不对垫片17施力,此时垫片17在第一弹簧15的作用下被限制于卡簧34上。It should be noted that the temperature sensing element 25 does not exert force on the gasket 17 under the condition of not being heated and elongated, and at this time, the gasket 17 is restricted on the retaining spring 34 under the action of the first spring 15 .

进一步的,可调内芯30的外部套设有第一O型圈(附图未示出),该第一O型圈的一侧与固定套28的内壁密封抵接。固定套28的外部套设有第二O型圈(附图未示出),该第二O型圈的一侧与第一功能孔12的内壁密封抵接。通过第一O型圈以及第二O型圈的设置,以解决第一功能孔12端密封装配的问题。Further, a first O-ring (not shown in the drawings) is sleeved on the outside of the adjustable inner core 30 , and one side of the first O-ring is in sealing contact with the inner wall of the fixing sleeve 28 . A second O-ring (not shown in the drawings) is sleeved outside the fixing sleeve 28 , and one side of the second O-ring is in sealing contact with the inner wall of the first functional hole 12 . Through the arrangement of the first O-ring and the second O-ring, the problem of sealing and assembling the end of the first functional hole 12 is solved.

进一步的,感温元件25包括伸缩段35以及感温段36,伸缩段35的一端与垫片17相抵接,伸缩段35的另一端与感温段36一体连接或组装连接,感温段36朝太阳能热水进水方向设置。感温段36上一体设置有定位凸块37,分流垫26套设于感温段36上,分流垫26的一侧与定位凸块37相抵接,分流垫26的另一侧与限位块27相抵接。Further, the temperature sensing element 25 includes a telescopic section 35 and a temperature sensing section 36, one end of the telescopic section 35 is in contact with the gasket 17, the other end of the telescopic section 35 is integrally connected or assembled with the temperature sensing section 36, and the temperature sensing section 36 Set in the direction of the solar hot water inlet. The temperature sensing section 36 is integrally provided with a positioning bump 37 , the shunt pad 26 is sleeved on the temperature sensing section 36 , one side of the shunt pad 26 is in contact with the positioning bump 37 , and the other side of the flow shunt 26 is connected with the limiting block 27 butted.

冷水状态下,感温元件25处于固定的自然长度,此时截流壳18的一端受压于第二弹簧24,使得截流壳18的另一端压紧并密封于固定套28上的封流面29。此时感温元件25的伸缩段靠近或刚好抵接垫片17,但不对垫片17产生压力。当水温升高时,感温段36受热出现内部膨胀,进而导致伸缩段伸长,使得伸缩段的一端压迫垫片17,进而传递至第一弹簧15上。而根据力的可传递性及其作用力与反作用力是相等的原理得出,感温元件25的伸缩段通过垫片17传递传递到第一弹簧15上的压力将同时导致定位凸块37对分流垫26产生相等的压力,并通过截流壳18传递至第二弹簧24上。此外,由于第二弹簧24将先于第一弹簧15被压缩,使得感温元件25将带着分流垫26和截流壳18一起向第二弹簧24方向运动,此时太阳能热水进水通路(J)导通,截流壳18通过第一密封槽以及第二密封槽内的密封圈来切断连通槽20与间隙14之间的连通。In the cold water state, the temperature sensing element 25 is at a fixed natural length. At this time, one end of the shut-off shell 18 is pressed by the second spring 24, so that the other end of the shut-off casing 18 is pressed and sealed against the sealing surface 29 on the fixed sleeve 28. . At this time, the telescopic section of the temperature sensing element 25 is close to or just abuts against the gasket 17 , but does not generate pressure on the gasket 17 . When the water temperature rises, the temperature-sensing section 36 is heated to cause internal expansion, which in turn causes the telescopic section to elongate, so that one end of the telescopic section presses the gasket 17 and transmits it to the first spring 15 . According to the principle of the transmittance of force and the principle that the action force and the reaction force are equal, the pressure transmitted from the telescopic section of the temperature sensing element 25 to the first spring 15 through the washer 17 will simultaneously cause the positioning bump 37 to The diverter pad 26 generates an equal pressure and transmits it to the second spring 24 through the shut-off shell 18 . In addition, since the second spring 24 will be compressed before the first spring 15, the temperature sensing element 25 will move towards the second spring 24 with the diverting pad 26 and the shut-off shell 18, and at this time the solar hot water inlet channel ( J) Conduction, the shut-off casing 18 cuts off the communication between the communication groove 20 and the gap 14 through the first sealing groove and the sealing ring in the second sealing groove.

进一步的,第二功能孔13内设置有用以抵触截流壳18的定位台阶38,截流壳18可在定位台阶38以及固定套28之间活动。当感温元件25受热以带动截流壳18向第二弹簧24方向运动,直至截流壳18的一端与定位台阶38相抵而停止运动。此时水温已经接近于太阳能热水器可供水温上限。若水温仍有小幅上升直至太阳能热水器可供的水温上限,使得感温元件25上的伸缩段35继续伸长,此时感温元件25因无法继续向第二弹簧24方向运动,而将反向通过伸缩段35压迫垫片17向第一弹簧15方向运动,进而压缩第一弹簧15。如此可确保感温元件25受热伸长的过程不至于压损其本身及其关联配件,当水温逐渐降低至常温时,感温元件25将逐渐缩短至初始的固定长度。Further, the second functional hole 13 is provided with a positioning step 38 for resisting the shut-off casing 18 , and the shut-off casing 18 can move between the positioning step 38 and the fixing sleeve 28 . When the temperature sensing element 25 is heated, it drives the shut-off casing 18 to move in the direction of the second spring 24 until one end of the shut-off casing 18 abuts against the positioning step 38 and stops moving. At this time, the water temperature is close to the upper limit of the water temperature available for the solar water heater. If the water temperature still rises slightly to the upper limit of the water temperature available for the solar water heater, so that the telescopic section 35 on the temperature sensing element 25 continues to stretch, at this time the temperature sensing element 25 cannot continue to move in the direction of the second spring 24, and will reverse The washer 17 is forced to move in the direction of the first spring 15 by the telescopic section 35 , thereby compressing the first spring 15 . This ensures that the temperature sensing element 25 will not be damaged by pressure and its associated accessories during the process of heating and elongation. When the water temperature gradually decreases to normal temperature, the temperature sensing element 25 will gradually shorten to the initial fixed length.

进一步的,分流垫26远离定位凸块37的一端设置有沉孔39,分流垫26的外圈上设置有若干周向分布的分流槽40,每个分流槽40均与沉孔39相连通。太阳能热水在通过分流垫26时,可依次先通过沉孔39、分流槽40进入截流壳18的内部,进而再通过间隙14与阀芯组件5导通。此外,位于分流垫26两侧的水均可与通过分流槽40、沉孔39双向流通。Further, the end of the distribution pad 26 away from the positioning bump 37 is provided with a counterbore 39 , and the outer ring of the distribution pad 26 is provided with a number of circumferentially distributed distribution grooves 40 , each of which is communicated with the counterbore 39 . When the solar hot water passes through the diverter pad 26 , it can enter the interior of the shut-off casing 18 through the countersunk hole 39 and the diverter groove 40 in sequence, and then communicate with the valve core assembly 5 through the gap 14 .

The connecting hole 42 has a built-in check valve 43. The check valve 43 Allowing fluid to flow from the hot runner 7 into the cold runner 8 has the effect of preventing backflow. It should be noted that the connecting hole 42 is a counterbore close to the third functional hole 41 , and the check valve 43 is placed in the counterbore so that the check valve 43 cannot enter the cold runner 8 through the baffle.

第三功能孔41内螺纹连接有可将第二功能孔与第三功能孔轴向连通切断的堵头44,堵头44的一端设置有内六角盲孔45作为扳手位,堵头44的另一端设置有多个沿周向均匀分布的凸柱46,任意两个凸柱46之间设置有过水槽47,堵头44上还设置有用以装配O型圈的沟槽48,以通过O型圈来实现堵头44与第三功能孔41之间的密封。每个凸柱46的一端均抵接止回阀43,以防止止回阀43在出水端受压出现反向移动,确保止回阀43的止回作用长期存在。The third functional hole 41 is internally threaded with a plug 44 that can cut off the axial communication between the second functional hole and the third functional hole.

One side of the second functional hole 13 is provided with an escape hole 50 that can communicate with the cavity 49 , and the other end of the cavity 49 can communicate with the second functional hole 13 through the escape hole 50 . When one end of the shut-off casing 18 abuts against the positioning step 38 on the second functional hole 13 , the casing of the shut-off casing 18 can block the escape hole 50 to cut off the communication between the second functional hole 13 and the cavity 49 .

该淋浴龙头开启使用时,若太阳能热水进水组件3的管道中存在冷水,则首先启用燃气热水器的热水,并同时将太阳能热水进水组件3的管道中存在冷水排出至冷流道8内与普通自来水混合。因使用温水需同时消耗热水与冷水,故待太阳能热水进水组件3的管道中冷水逐渐使用完后,太阳能的热水将进入龙头自动取代燃气热水器的热水供应,此时进入太阳能热水与普通自来水混合的通常使用状态,当长时间使用导致太阳能热水消耗完后温度逐渐降低,此时截流壳18封堵间隙14,即自动关闭水路J,而连通水路M,同时自动开启燃气热水器进水口(即连通水路L)。When the shower faucet is turned on, if there is cold water in the pipeline of the solar hot water inlet assembly 3, the hot water of the gas water heater will be activated first, and at the same time, the cold water in the pipeline of the solar hot water inlet assembly 3 will be discharged to the cold runner. 8 Mix with ordinary tap water. Because the use of warm water needs to consume both hot water and cold water, after the cold water in the pipeline of the solar hot water inlet component 3 is gradually used up, the hot water from the solar energy will enter the faucet to automatically replace the hot water supply of the gas water heater. In the normal use state of mixing water and ordinary tap water, when the solar hot water is consumed for a long time, the temperature gradually decreases. At this time, the interception shell 18 blocks the gap 14, that is, the waterway J is automatically closed, and the waterway M is connected, and the gas is automatically turned on. The water inlet of the water heater (ie, the connecting water channel L).

此外,以下将详细介绍使用过程:In addition, the following will describe the usage process in detail:

当太阳能热水进水组件3所流出的水为冷水时,此时截流壳18的一端与固定套28相抵,截流壳18的另一端并未封堵让位孔50,因此太阳能热水进水组件3所流出的冷水仅能从让位孔50处朝向腔体49内流入,并依次通过过水槽47、止回阀43进入冷流道8内。When the water flowing out of the solar hot water inlet assembly 3 is cold water, one end of the shut-off shell 18 is in contact with the fixing sleeve 28, and the other end of the shut-off casing 18 does not block the escape hole 50, so the solar hot water is fed into the water. The cold water flowing out of the assembly 3 can only flow into the cavity 49 from the escape hole 50 and enter the cold runner 8 through the water passage 47 and the check valve 43 in sequence.

当太阳能热水进水组件3所流出的水为热水时,此时截流壳18的一端与第二功能孔13上的定位台阶38相抵,以封堵让位孔50。上述截流壳18封堵让位孔50的运动方式与截流壳18封堵燃气热水器的进水方式一致,且同步完成。此时太阳能热水进水通路导通。When the water flowing out of the solar hot water inlet assembly 3 is hot water, one end of the shut-off shell 18 abuts the positioning step 38 on the second functional hole 13 to block the escape hole 50 . The above-mentioned movement mode of blocking the escape hole 50 by the shut-off shell 18 is the same as that of blocking the water inlet of the gas-fired water heater by the shut-off casing 18 , and is completed synchronously. At this time, the solar hot water inlet channel is turned on.

进一步的,截流壳18采用热导系数小的材料制成,具有导热少的特性,使得被截流壳18隔离的一侧第二功能孔13的水温不受另一侧连通槽20水温的变化所影响。Further, the cut-off shell 18 is made of a material with a small thermal conductivity, which has the characteristics of less heat conduction, so that the water temperature of the second functional hole 13 on one side isolated by the cut-off shell 18 is not affected by the change of the water temperature of the communication groove 20 on the other side. influences.

进一步的,冷水进水组件2与阀体1连接处设置有限流止回阀51。该限流止回阀51可不仅仅可允许水流单向通过而无法逆流,还具有限流的作用。同等水压下,限流止回阀51的最大流量预设值小于止回阀43的最大流量预设值。Further, a limited flow check valve 51 is provided at the connection between the cold water inlet assembly 2 and the valve body 1 . The flow-limiting check valve 51 can not only allow the water flow to pass in one direction and cannot flow back, but also have the function of limiting the flow. Under the same water pressure, the preset maximum flow rate of the limiting check valve 51 is smaller than the preset maximum flow rate of the check valve 43 .

当龙头初次使用时,打开龙头把手6,此时的冷水由太阳能热水器出水管道及普通自来水同时供给。通过将止回阀43的最大流量预设值大于限流止回阀51的最大流量预设值,以更快速度消耗来自于太阳能热水器出水管道内的冷水,进而更快的使用来自太阳能热水器中的热水。When the faucet is used for the first time, the handle 6 of the faucet is opened, and the cold water at this time is supplied by the water outlet pipe of the solar water heater and the ordinary tap water at the same time. By setting the maximum flow preset value of the check valve 43 to be greater than the maximum flow preset value of the limiting check valve 51, the cold water from the water outlet pipe of the solar water heater can be consumed at a faster rate, and the cold water from the solar water heater can be used more quickly. of hot water.

进一步的,阀芯组件5上包括有冷水进水孔52、热水进水孔53以及混水出水孔54,冷流道8与阀芯组件5上的冷水进水孔52相连通,热流道7与阀芯组件5上的热水进水孔53相连通,冷水进水孔52、热水进水孔53均与混水出水孔54相连通。阀芯组件5为现有技术,在此不加以详细赘述。Further, the valve core assembly 5 includes a cold water inlet hole 52, a hot water inlet hole 53 and a mixed water outlet hole 54, the cold flow channel 8 is communicated with the cold water inlet hole 52 on the valve core assembly 5, and the hot flow channel 7 is communicated with the hot water inlet hole 53 on the valve core assembly 5 , and the cold water inlet hole 52 and the hot water inlet hole 53 are both communicated with the mixed water outlet hole 54 . The valve core assembly 5 is in the prior art and will not be described in detail here.
