The first cover body 10 is provided with a water inlet port 12 communicating with the water inlet cavity 11. The first cover body 10 is provided with a water outlet hole 13 communicating with the water inlet cavity 11. The second cover 20 is provided with a drainage cavity 21 communicating with the water outlet 13. The second cover 20 is provided with a water outlet port 22 communicating with the drainage cavity 21. The water pressure fluctuation component 30 includes: an electromagnet 31 connected to the first cover body 10 and a movable metal piece 32 located in the water inlet cavity 11. The arrangement of the movable metal piece 32 relative to the water outlet 13. The electromagnet 31 is used to connect a current source that changes periodically to generate a driving force that drives the movable metal piece 32 to reciprocate periodically. The movable metal piece 32 is used to impact the water outlet hole 13 during the periodical reciprocating motion to generate a pulsed water pressure fluctuation in the drainage cavity 21.
如图2所示，在本实施例中，电磁铁31包括：连接在第一盖体10上的线圈组件311和穿设在线圈组件311中的固定金属件312。固定金属件312位于活动金属件32背离出水孔13的一端。线圈组件311连接周期性变化的电流源，使得固定金属件312磁化以产生带动活动金属件32往复运动的驱动力。As shown in FIG. 2, in this embodiment, the electromagnet 31 includes a coil component 311 connected to the first cover body 10 and a fixed metal piece 312 passing through the coil component 311. The fixed metal piece 312 is located at an end of the movable metal piece 32 facing away from the water outlet 13. The coil component 311 is connected to a current source that changes periodically, so that the fixed metal piece 312 is magnetized to generate a driving force that drives the movable metal piece 32 to reciprocate.
进一步地，在本实施例中，固定金属件312可以为软铁。在其他实施例中，该固定金属件312也可以为硅钢。而软铁或者硅钢的优势在于，在线圈组件311断电时，软铁或者硅钢的消磁速度快，灵敏度更好。Further, in this embodiment, the fixed metal piece 312 may be soft iron. In other embodiments, the fixed metal part 312 may also be silicon steel. The advantage of soft iron or silicon steel is that when the coil component 311 is powered off, the degaussing speed of the soft iron or silicon steel is fast and the sensitivity is better.
而在本实施例中，活动金属件32可以为铁芯或者其他硬度适中的金属块。另外，由于活动金属件32需要长期浸泡在水中，因此，在其他实施例中，还可以在活动金属件32的表面设置电镀层，起到防锈防腐蚀的作用。又或者是在活动金属件32的表面包覆塑胶膜或者包裹塑胶层，起到防锈防腐蚀的作用。In this embodiment, the movable metal part 32 may be an iron core or other metal block with moderate hardness. In addition, since the movable metal piece 32 needs to be immersed in water for a long time, in other embodiments, a plating layer may be provided on the surface of the movable metal piece 32 to prevent rust and corrosion. Or, the surface of the movable metal part 32 is covered with a plastic film or a plastic layer to play a role of preventing rust and corrosion.
此外，在本实施例中，线圈组件311的中心处形成可以供活动金属件32的滑动的滑槽3111，其可以提高活动金属件32的工作稳定性。In addition, in the present embodiment, a chute 3111 is formed at the center of the coil assembly 311 for the movable metal piece 32 to slide, which can improve the working stability of the movable metal piece 32.
进一步地，在其他实施例中，第一盖体10还设有竖直设置于进水腔11内的导柱。导柱的一端连接在进水腔11的底部；导柱相对的另一端穿设在活动金属件32中。导柱用于限制活动金属件32的活动轨迹，提高装置运行的稳定性。Further, in other embodiments, the first cover body 10 is further provided with a guide post vertically arranged in the water inlet cavity 11. One end of the guide post is connected to the bottom of the water inlet cavity 11; the opposite end of the guide post is penetrated in the movable metal piece 32. The guide post is used to limit the moving trajectory of the movable metal part 32 and improve the stability of the device operation.
另外，在本实施例中，出水孔13为多个且以阵列分布在进水腔11。阵列分布的多个出水孔13可以让排水腔21内出现多个波动处，使得排水腔21中的水压波动效果更好。In addition, in this embodiment, there are a plurality of water outlet holes 13 and they are distributed in the water inlet cavity 11 in an array. The plurality of water outlet holes 13 distributed in an array can cause multiple fluctuations in the drainage cavity 21, so that the water pressure fluctuation in the drainage cavity 21 has a better effect.
考虑到活动金属件32在往复运动的过程中，会迫使水流产生逆流的风险，在其他实施例中，进水端口12还可以连接有单向阀。单向阀的导通方向 为从进水端口12向进水腔11。单向阀可以防止活动金属件32往复运动的过程中进水腔11内的水流逆流向进水端口12。Considering that during the reciprocating movement of the movable metal part 32, the risk of water flowing back will be forced, in other embodiments, the water inlet port 12 may also be connected with a check valve. The conducting direction of the check valve is from the water inlet port 12 to the water inlet cavity 11. The one-way valve can prevent the water flow in the water inlet cavity 11 from flowing back to the water inlet port 12 during the reciprocating movement of the movable metal part 32.
工作原理简述：Brief description of working principle:
在本实施例中，该水压波动激励装置100采用竖直放置的使用方式。如图2所示，在电磁铁31断电的状态下，活动金属件32在自身的重力作用下，压在位于进水腔11的底部的出水孔13上，使得水流被隔断而无法进入到排水腔21。如图3所示，电磁铁31通电的状态下，活动金属件32被电磁铁31向上吸附以离开出水孔13，此时，水流从进水腔11进入到排水腔21中，接着，电磁铁31再次断电，活动金属件32在自身重力的作用下，克服浮力下移并且压在出水孔13上，水流再次被隔断。在活动金属件32的下移过程中，对从进水腔11流到排水腔21的水流产生一个推力，从而增强出水压力峰值。通过控制线圈组件311的通断电频率就可以控制活动金属件32上下活动频率，从而实现水压波动的脉冲效果。In this embodiment, the water pressure fluctuation excitation device 100 is used in a vertical position. As shown in FIG. 2, in the state that the electromagnet 31 is powered off, the movable metal piece 32 is pressed by the gravity of the own body on the water outlet hole 13 at the bottom of the water inlet cavity 11, so that the water flow is blocked and cannot enter. Drainage chamber 21. As shown in FIG. 3, when the electromagnet 31 is energized, the movable metal piece 32 is attracted upward by the electromagnet 31 to leave the water outlet hole 13. At this time, the water flows from the water inlet chamber 11 into the drainage chamber 21, and then the electromagnet 31 is powered off again, and the movable metal piece 32 moves downwards under the action of its own gravity to overcome the buoyancy and presses on the water outlet hole 13, and the water flow is blocked again. During the downward movement of the movable metal part 32, a thrust is generated to the water flow flowing from the water inlet cavity 11 to the drainage cavity 21, thereby enhancing the peak pressure of the water outlet. By controlling the on-off frequency of the coil component 311, the up-and-down movement frequency of the movable metal piece 32 can be controlled, thereby realizing the pulse effect of water pressure fluctuation.
上述水压波动激励装置100，使用时，可以将该水压波动激励装置100安装在喷枪的进水口处以调节喷枪的水流，使得喷枪可以喷出波动式的水流。水流从第一盖体10的进水端口12中进入到进水腔11中。而进水腔11则通过出水孔13与第二盖体20的排水腔21连通，因此，水流可以流入到排水腔21中，并且通过与排水腔21连通的出水端口22流入到喷枪内。使用时，水压波动组件30中的电磁铁31连接周期性变化的电流源，电磁铁31产生周期性变化的磁力，而该磁力可以带动活动金属件32相对于出水孔13往复运动。活动金属件32在周期性往复运动的过程中冲击出水孔13，使得排水腔21中产生脉冲式的水压波动，进而使得从出水端口22流出的水流具有波动效果，并且水流的压力峰值高于水流进入进水端口12时的水压，从而可以用更少的水达到更强的清洗效果，并且波动式的水流还能起到脉冲按摩的作用。When the water pressure fluctuation excitation device 100 is used, the water pressure fluctuation excitation device 100 can be installed at the water inlet of the spray gun to adjust the water flow of the spray gun, so that the spray gun can spray the wave-shaped water flow. The water flow enters the water inlet chamber 11 from the water inlet port 12 of the first cover 10. The water inlet chamber 11 communicates with the drainage chamber 21 of the second cover 20 through the water outlet hole 13. Therefore, water can flow into the drainage chamber 21 and flow into the spray gun through the water outlet port 22 communicating with the drainage chamber 21. During use, the electromagnet 31 in the water pressure fluctuation component 30 is connected to a periodically changing current source. The electromagnet 31 generates a periodically changing magnetic force, and the magnetic force can drive the movable metal piece 32 to reciprocate relative to the water outlet 13. During the periodical reciprocating movement of the movable metal piece 32, the water outlet 13 is impacted, so that the pulsed water pressure fluctuations are generated in the drainage cavity 21, and the water flow from the water outlet port 22 has a wave effect, and the pressure peak of the water flow is higher than The water pressure when the water flow enters the water inlet port 12, so that a stronger cleaning effect can be achieved with less water, and the wave-shaped water flow can also serve as a pulse massage.
实施例二Example two
如图4所示，其为本发明的实施例二的水压波动激励装置100a。As shown in FIG. 4, it is a water pressure fluctuation excitation device 100 a according to the second embodiment of the present invention.
本实施例与实施例一的区别在于：在本实施例中的水压波动激励装置 100a中，活动金属件32与电磁铁31之间还设有弹性件40。弹性件40用于产生朝向出水孔13的形变力。弹性件40可以增强活动金属件32对出水孔13的冲击力。The difference between this embodiment and the first embodiment is that in the water pressure fluctuation excitation device 100a in this embodiment, an elastic member 40 is further provided between the movable metal member 32 and the electromagnet 31. The elastic member 40 is used to generate a deforming force toward the water outlet hole 13. The elastic member 40 can enhance the impact force of the movable metal member 32 on the water outlet 13.
进一步地，在本实施例中，弹性件40为弹簧。在其他实施例中，该弹性件40也可以为弹片或者弹性胶块。Further, in this embodiment, the elastic member 40 is a spring. In other embodiments, the elastic member 40 may also be an elastic piece or an elastic rubber block.
在本实施例中，由于引入了弹性件40，所以在竖直放置的状态下，其工作原理与实施例一的区别在于引入了弹性件40的弹性势能。在电磁铁31通电时，电磁铁31产生的磁力需要克服活动金属件32的自重和弹性件40的弹力。而在电磁铁31断电时，活动金属件32则在自重和弹性件40的弹力的双重作用下移动，从而强化活动金属件32的下移驱动力。而弹性件40的引入，也可以使得该水压波动激励装置100a可以以非竖直状态摆放，因为在电磁铁31断电时，弹性件40可以处于压缩状态，使得活动金属件32压紧在出水孔13上，而电磁铁31通电时，使得弹性件40进一步压缩。In this embodiment, since the elastic member 40 is introduced, the working principle of the elastic member 40 is different from that of the first embodiment in the state of being placed vertically, because the elastic potential energy of the elastic member 40 is introduced. When the electromagnet 31 is energized, the magnetic force generated by the electromagnet 31 needs to overcome the weight of the movable metal member 32 and the elastic force of the elastic member 40. When the electromagnet 31 is powered off, the movable metal member 32 moves under the dual action of its own weight and the elastic force of the elastic member 40, thereby strengthening the downward driving force of the movable metal member 32. The introduction of the elastic member 40 can also make the water pressure fluctuation excitation device 100a be placed in a non-vertical state, because when the electromagnet 31 is powered off, the elastic member 40 can be in a compressed state, so that the movable metal member 32 is compressed. When the electromagnet 31 is energized on the water outlet hole 13, the elastic member 40 is further compressed.
实施例三Example three
如图5所示，其为本发明的实施例三的水压波动激励装置100b。As shown in FIG. 5, it is a water pressure fluctuation excitation device 100 b according to the third embodiment of the present invention.
本实施例与实施例一的区别在于：在本实施例中的水压波动激励装置100b中，活动金属件32上还连接有永磁铁50。永磁铁50位于活动金属件32靠近电磁铁31的一端。永磁铁50可以产生与电磁铁31之间的斥力，增强活动金属件32对出水孔13的冲击力。The difference between this embodiment and the first embodiment is that in the water pressure fluctuation excitation device 100 b in this embodiment, a permanent magnet 50 is further connected to the movable metal piece 32. The permanent magnet 50 is located at an end of the movable metal member 32 near the electromagnet 31. The permanent magnet 50 can generate a repulsive force with the electromagnet 31 to enhance the impact force of the movable metal member 32 on the water outlet 13.
在本实施例中，由于引入了永磁铁50，所以在竖直放置的状态下，其工作原理与实施例一的区别在于引入了永磁铁50的磁吸力。在电磁铁31通入正向电流时，电磁铁31产生的磁力需要克服活动金属件32的自重并且与永磁铁50相吸，活动金属件32上移。而在电磁铁31通入反向电流时，活动金属件32则在自重和电磁铁31与永磁铁50之间的斥力作用下移动，从而强化活动金属件32的下移驱动力。而永磁铁50的引入，也可以使得该水压波动激励装置100b可以以非竖直状态摆放，因为，在电磁铁31断电时，利用永磁铁50将活动金属件32吸附到电磁铁31处(当永磁铁50所产生的吸附力 大于活动金属件32的自重时，也可以竖直摆放)，而电磁铁31通电时，使得电磁铁31与永磁铁50相斥，使得活动金属件32压在出水孔13上。In this embodiment, since the permanent magnet 50 is introduced, the working principle of the permanent magnet 50 is different from that of the first embodiment in the state of being placed vertically, because the magnetic attraction of the permanent magnet 50 is introduced. When the electromagnet 31 passes a forward current, the magnetic force generated by the electromagnet 31 needs to overcome the weight of the movable metal member 32 and attract the permanent metal 50, and the movable metal member 32 moves upward. When the electromagnet 31 applies a reverse current, the movable metal member 32 moves under the action of its own weight and the repulsive force between the electromagnet 31 and the permanent magnet 50, thereby strengthening the downward driving force of the movable metal member 32. The introduction of the permanent magnet 50 can also make the water pressure fluctuation excitation device 100b be placed in a non-vertical state, because when the electromagnet 31 is powered off, the movable metal piece 32 is attracted to the electromagnet 31 by the permanent magnet 50 (When the adsorption force generated by the permanent magnet 50 is greater than the self-weight of the movable metal part 32, it can also be placed vertically), and when the electromagnet 31 is energized, the electromagnet 31 repels the permanent magnet 50, making the movable metal part 32 is pressed on the water outlet hole 13.
实施例四Embodiment 4
如图6所示，其为本发明的实施例四的水压波动激励装置100c。As shown in FIG. 6, it is a water pressure fluctuation excitation device 100c according to the fourth embodiment of the present invention.
本实施例中的水压波动激励装置100c结合了实施例二中的弹性件40和实施例三中的永磁铁50，两者共同提升水压波动的效果。The water pressure fluctuation excitation device 100c in this embodiment combines the elastic member 40 in the second embodiment and the permanent magnet 50 in the third embodiment, and both of them jointly improve the effect of the water pressure fluctuation.
实施例五Example 5
如图7所示，其为本发明的实施例五的水压波动激励装置100d。As shown in FIG. 7, it is a water pressure fluctuation excitation device 100 d according to the fifth embodiment of the present invention.
本实施例与实施例三的区别在于：本实施例的水压波动激励装置100d中，活动金属件32的内部开设有空腔321。在活动金属件32内开设空腔321可以调节活动金属件32的密度，有利于调整活动金属件32的自重与浮力之间的比值。The difference between this embodiment and the third embodiment is that in the water pressure fluctuation excitation device 100d of this embodiment, a cavity 321 is provided inside the movable metal member 32. Opening a cavity 321 in the movable metal piece 32 can adjust the density of the movable metal piece 32 and is beneficial to adjusting the ratio between the self-weight and the buoyancy of the movable metal piece 32.
实施例六Example Six
如图8所示，其为本发明的实施例六的水压波动激励装置100e。As shown in FIG. 8, it is a water pressure fluctuation excitation device 100 e according to the sixth embodiment of the present invention.
本实施例中的水压波动激励装置100e在实施例四的基础上，融合了实施例五中的金属件的空腔321，进一步优化水压波动的效果。The water pressure fluctuation excitation device 100e in this embodiment is based on the fourth embodiment and incorporates the cavity 321 of the metal part in the fifth embodiment to further optimize the effect of the water pressure fluctuation.
