[0001] The utility model relates to the technical field of water purification equipment, in particular to a Hall induction structure and a water purification system. Background Art

[0002] The Hall sensor element can determine whether to turn on or off the signal by sensing the magnetic induction intensity. When the Hall sensor element is applied, such as in a water purification system, the Hall sensor element and the magnet form a sensing structure. The Hall sensor element sends a signal to turn off or turn on the faucet in the water purification system by sensing the magnetic induction intensity of the magnet, thereby achieving water discharge. However, in the entire sensing structure, the distance between the magnet and the Hall sensor element is not very different. At the same time, the Hall sensor element has relatively high requirements for the position of the magnet and the size of the magnetic flux. If the magnet specifications or distance are deviated, it may cause confusion in the Hall sensor signal, resulting in false opening or failure to discharge water. Summary of the invention

[0044] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0046] Embodiment 1:

[0047] like Figure 1-5The Hall sensor structure shown includes a housing 1, a base 2, a magnet 3, a magnetic column 4, a Hall sensor element 5, and a magnetic screen patch 6. Each component is described in detail below.

[0048] The housing 1 covers all parts, and specifically includes an upper housing 10 and a lower housing 11. The upper housing 10 and the lower housing 11 are connected to form a whole, and the lower housing 11 can rotate relative to the upper housing 10. For example, rotating the lower housing 11 can make the lower housing 11 rotate relative to the upper housing around its own axis, or the lower housing 11 is also equivalent to a knob for rotation. Figure 3 , 4 The specific rotation method can be a thread method, or other methods are also possible.

[0049] The base 2 is connected to the upper shell 10, and one side of the base 2 faces the lower shell 11, and the other side of the base 2 faces the upper shell 10. The base 2 is provided with through holes penetrating both sides thereof, such as Figure 5 shown.

[0050] The magnet 3 is connected to the lower shell 11 so that the magnet 3 is located on one side of the base 2 . Rotating the lower shell 11 can drive the magnet 3 to move relative to the base 2 so that it is aligned with or offset from the through hole on the base 2 .

[0051] The magnetic conductive column 4 is arranged on the other side of the base 2, that is, located in the upper shell 10, and the magnetic conductive column 4 is partially located in the through hole or facing the through hole. Figure 5 As shown: one end of the magnetic conductive column 4 is located in the through hole, and the other end of the magnetic conductive column 4 extends toward a side away from the magnet 3.

[0052] The Hall sensor element 5 is located on the other side of the base 2, that is, also located in the upper housing 10, and facing the through hole. Figure 3 , 4 As shown, the Hall sensor element 5 is disposed on the upper housing 10 , and the other end of the magnetic conductive column 4 extends toward the Hall sensor element 5 .

[0053] The screen magnetic patch 6 is arranged on the surface of the other side of the base 2, covering the part except the through hole, such as Figure 3 , 4 shown.

[0054] In this way, when the lower shell 11 is rotated to drive the magnet 3 to face the through hole on the base 2, the magnet 3 will magnetize the magnetic column 4 in the through hole, and the Hall sensing element 5 above the magnetic column 4 can sense the magnetic signal, thereby sending an output voltage signal to control functions such as turning on; when the lower shell 11 is rotated to drive the magnet 3 to move to other positions on one side of the base 2 and staggered with the through hole on the base 2, the magnetic shield patch 6 on the base 2 can attenuate or shield the magnetic induction signal, making it impossible for the Hall sensing element 5 to sense the magnetic signal, and the function such as turning off is maintained.

[0055] In one implementation of this embodiment: the through hole includes a first through hole 20 and a second through hole 21, the first through hole 20 and the second through hole 21 are respectively provided with a magnetic conductive column 4, and the first through hole 20 and the second through hole 21 are both provided with a Hall sensor element 5 at the positions facing each other. When the lower housing 11 is rotated to drive the magnet 3 to face the first through hole 20 on the base 2, as shown in FIG. Figure 6 As shown, the magnet 3 will magnetize the magnetic column 4 in the first through hole 20, and the Hall sensor 5 above the magnetic column 4 can sense the magnetic signal, thereby sending out an output voltage signal to control functions such as opening; when the lower shell 11 is rotated to drive the magnet 3 to face the second through hole 21 on the base 2, as shown in FIG. Figure 7 As shown, the magnet 3 will magnetize the magnetic column 4 in the second through hole 21, and the Hall sensor element 5 above the magnetic column 4 can sense the magnetic signal, thereby sending out an output voltage signal and controlling functions such as opening. Moreover, since the two Hall sensor elements 5 sense the magnetic signal, each Hall sensor element 5 can send out a different output voltage signal to control different opening functions, thereby realizing multi-speed control. When the lower shell 11 is rotated to drive the magnet 3 to move to other positions on one side of the base 2, and the first through hole 20 and the second through hole 21 on the base 2 are staggered, as shown in FIG. Figure 8 As shown, the magnetic shield patch 6 on the base 2 can attenuate or shield the magnetic induction signal, so that the Hall sensor element 5 cannot sense the magnetic signal, and the function of the closed state is maintained. Of course, the number of through holes can be set to be more to achieve more gear control, which will not be listed here.

[0056] Embodiment 2:

[0057] This embodiment is an application of a Hall sensor structure of an embodiment.

[0058] like Fig. 9 A water purification system shown includes a filter unit 7 and a faucet 8 . The faucet 8 is connected to the filter unit 7 via a pipeline 9 . The faucet 8 is provided with a Hall sensing structure 80 , which is used to control the water output of the faucet 8 .

[0059] In this way, when the lower shell 11 is rotated to drive the magnet 3 to face the through hole on the base 2, the magnet 3 will magnetize the magnetic column 4 in the through hole, and the Hall sensor element 5 above the magnetic column 4 can sense the magnetic signal, thereby sending out an output voltage signal, and the faucet 8 is opened; when the lower shell 11 is rotated to drive the magnet 3 to move to other positions on the side of the base 2 and staggered from the through hole on the base 2, the magnetic shield patch 6 on the base 2 can attenuate or shield the magnetic induction signal, so that the Hall sensor element 5 cannot sense the magnetic signal, and the faucet 8 is closed. The Hall sensor element 5 can be associated with, for example, a solenoid valve in the faucet 8, and send out a signal to control the solenoid valve, thereby controlling the on and off of the water path. Of course, it is not limited to this. How the Hall sensor element 5 controls the faucet 8 does not involve the invention point of this application and will not be listed here.

[0060] In one implementation of this embodiment, the filter unit 7 has a raw water inlet 70, a normal temperature pure water outlet 71, and a heated pure water outlet 72. The raw water inlet 70 is used to connect to a water source, and the normal temperature pure water outlet 71 and the heated pure water outlet 72 are connected to the tap 8 through a pipeline 9. The raw water entering the filter unit 7 can be heated or discharged to the tap 8 at normal temperature after being filtered by the filter unit 7.

[0061] When the lower housing 11 is rotated to drive the magnet 3 to face the first through hole 20 on the base 2, as shown in FIG. Figure 6 As shown, the magnet 3 will magnetize the magnetic column 4 in the first through hole 20, and the Hall sensor 5 above the magnetic column 4 can sense the magnetic signal, thereby sending an output voltage signal, and the faucet 8 is opened and connected to the normal temperature pure water outlet 71, and normal temperature water can be discharged; when the lower shell 11 is rotated to drive the magnet 3 to face the second through hole 21 on the base 2, as shown in FIG. Figure 7 As shown, the magnet 3 will magnetize the magnetic column 4 in the second through hole 21, and the Hall sensor element 5 above the magnetic column 4 can sense the magnetic signal, thereby sending an output voltage signal, and the faucet 8 is opened and connected to the heating pure water outlet 72, and hot water can be discharged; when the lower shell 11 is rotated to drive the magnet 3 to move to other positions on one side of the base 2, and the first through hole 20 and the second through hole 21 on the base 2 are staggered, as shown in FIG. Figure 8 As shown, the magnetic shielding patch 6 on the base 2 can attenuate or shield the magnetic induction signal, so that the Hall sensor element 5 cannot sense the magnetic signal and the faucet 8 is closed.
