[0034] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the structure of the water storage device 10 in some embodiments, Figure 2 for Figure 1 The water storage device 10 shown in the figure omits the cover 115. Figure 3 for Figure 2 The water storage device 10 provided in the present application has a water storage container 11 capable of storing liquid, and the water storage container 11 is provided with a water outlet 113, and the liquid in the water storage container 11 can flow out from the water outlet 113. The water storage device 10 includes but is not limited to being used in a toilet, for example, in a cleaning water path or a flushing water path of a toilet.

[0035] When the water storage device 10 is used in the cleaning water circuit, the toilet may also include a spray gun (not shown in the figure), and a water pump (not shown in the figure) may be provided between the water storage container 11 and the spray gun. The water pump can extract the liquid in the water storage container 11 from the water outlet 113 and supply water to the spray gun, so that the spray gun can spray the user. The cleaning water circuit of the toilet may also be provided with a heating element such as a heat pipe for heating the cleaning water (not shown in the figure). After the cleaning water is heated, it is sprayed from the spray gun to spray the user, which can improve the user experience. When the water storage device 10 is used for flushing the water circuit, the water pump in the flushing water circuit can extract the liquid in the water storage container 11 from the water outlet 113 to flush the siphon (not shown) of the toilet. Of course, the application scenarios and products of the water storage device 10 are not limited to the records of this application, and the water storage device 10 can also be used in any applicable scenario or product that requires water supply. The water storage device 10 provided in the present application can realize global water level detection, for example, it can detect any water level change between the lowest water level and the highest water level in the water storage container 11.

[0036] Furthermore, in some embodiments, the water storage device 10 further includes a rod 12, a floating member 13, a magnetic element 14 and a Hall sensor 15. The rod 12 and the floating member 13 are both disposed in the water storage container 11. The rod 12 can rotate relative to the water storage container 11 and includes a first end 121 and a second end 122 that are away from each other. The floating member 13 is rotatably connected to the first end 121 of the rod 12. The magnetic element 14 is disposed at the second end 122 of the rod 12. The magnetic element 14 includes but is not limited to any suitable element capable of generating a magnetic field, such as a magnet, a magnet, an electromagnet, etc. The Hall sensor 15 is disposed on the water storage container 11, and the Hall sensor 15 is used to sense the magnetic field generated by the magnetic element 14. The Hall sensor 15 corresponds to one of the positions on the movement path of the magnetic element 14 relative to the water storage container 11. In other words, when the magnetic element 14 moves to one of the positions on the movement path relative to the water storage container 11 along with the rod 12, the magnetic element 14 can be opposite to the Hall sensor 15, so that each position of the magnetic element 14 on the movement path will not be too far away from the Hall sensor 15, and the Hall sensor 15 can sense the magnetic field generated by the magnetic element 14.

[0037] It is understandable that the floating member 13 can float above the liquid in the water storage container 11. When the water level in the water storage container 11 changes, the floating member 13 can float up and down with the change of the water level, thereby driving the rod 12 to rotate relative to the water storage container 11, and then changing the position of the magnetic element 14 relative to the water storage container 11, so that the magnetic field of the magnetic element 14 sensed by the Hall sensor 15 changes, and the water level change in the entire water storage container 11 can be obtained according to the change of the magnetic field sensed by the Hall sensor 15. Therefore, the above-mentioned water storage device 10 can detect any water level change between the highest water level and the lowest water level in the water storage container 11 through a magnetic element 14 and a Hall sensor 15, without the need to set multiple water level sensing devices along the height direction, which is conducive to simplifying the structure of the water storage device 10 and reducing the preparation cost of the water storage device 10.

[0038] At the same time, the realization of global water level detection is also conducive to protecting various components in the toilet. For example, when the water storage device 10 is used for the cleaning water circuit of the toilet, if the water replenishment mechanism of the water storage container 11 is cut off, the water storage device 10 can sense the decrease in the water level in the water storage container 11, so that it can promptly control the heating element in the cleaning water circuit to stop heating when the water level drops to the critical value or the lowest water level, thereby avoiding the damage or shortening of the life of heating elements such as heat pipes due to empty burning. When the water storage device 10 is used for the flushing water circuit of the toilet, when the water level in the water storage container 11 drops, the water storage device 10 can promptly adjust the operating parameters of the water pump in the flushing water circuit, such as reducing the speed of the water pump or switching the toilet to a small flush mode, reducing the flushing volume and / or flushing time, which is conducive to avoiding the situation where the water pump is damaged due to empty running.

[0039] In some embodiments, the water storage device 10 may further include a control element 16, which is electrically connected to the Hall sensor 15 and is used to obtain the water level in the water storage container 11 according to the magnetic field sensed by the Hall sensor 15. For example, the magnetic field parameters that the Hall sensor 15 can sense when the floating member 13 is at different heights in the water storage container 11 can be preset according to the structural design of the water storage device 10, so as to obtain the water level of the water storage container 11 according to the correspondence between the magnetic field parameters sensed by the Hall sensor 15 and the preset height value of the floating member 13. When the water storage device 10 is used on a toilet, the control element 16 can be a central processor of the toilet, or a chip specifically used to sense the water level of the water storage container 11.

[0040] The specific structure of the floating member 13 is not limited, as long as it can float up and down with the change of water level and drive the rod 12 to rotate relative to the water storage container 11. In some embodiments, the floating member 13 includes a rotating portion 131 and a buoy portion 132 connected to each other, the first end 121 of the rod 12 is provided with a rotating groove 1211, and the rod 12 is also provided with a connecting shaft 1212 located in the rotating groove 1211. The rotating portion 131 is at least partially located in the rotating groove 1211, and the connecting shaft 1212 passes through the rotating portion 131. The rotating portion 131 and the connecting shaft 1212 are rotatably matched, so that the floating member 13 as a whole can rotate relative to the rod 12. The buoy portion 132 can also be set as any other applicable floating structure such as a floating block.

[0041] In some embodiments, the water storage device 10 further includes a rotating shaft 17 connected to the rod 12. The rotating shaft 17 can be inserted into the rod 12 and formed integrally with the rod 12, or fixedly arranged on the side of the rod 12. The rotating shaft 17 is rotatably arranged in the water storage container 11. In the present application, the part where the rod 12 is connected to the rotating shaft 17 is named as the connecting position 123 of the rod 12. The distance from the connecting position 123 to the first end 121 is greater than the distance from the connecting position 123 to the second end 122. For example, the rotating shaft 17 divides the rod 12 into two parts, wherein the length of the part connected to the floating member 13 is greater than the length of the part where the magnetic element 14 is arranged. Therefore, when the floating member 13 floats up and down, the moving path length of the first end 121 is greater than the moving path length of the second end 122, so that the magnetic element 14 has a shorter moving path to correspond to the height difference between the highest water level and the lowest water level. In other words, using the lever principle to reduce the length of the movement path of the magnetic element 14 is beneficial to reducing the distance between the magnetic element 14 and the Hall sensor 15 at different positions on the movement path, which is beneficial to more sensitively sensing the magnetic field of the magnetic element 14 through a Hall sensor 15, and is also beneficial to reducing the space occupied by the movement path of the magnetic element 14 in the water storage container 11, thereby helping to reduce the size of the water storage device 10 and reduce the preparation cost.

[0042] In some embodiments, the water storage device 10 further includes two support members 18 spaced apart in the water storage container 11, the two ends of the rotating shaft 17 are rotatably disposed on the two support members 18, and the rod member 12 is located between the two support members 18. In some embodiments, the water storage container 11 has a mounting surface 1121 for mounting the Hall sensor 15, and the projection of the Hall sensor 15 on the mounting surface 1121 is located between the projections of the two support members 18 on the mounting surface 1121. The support member 18 can provide support and limit for the rotation of the rod member 12 in the water storage container 11, and is also conducive to providing a reference for the installation and positioning of the Hall sensor 15.

[0043] In some embodiments, the water storage container 11 includes an integrally formed bottom plate 111 and a side plate 112. The side plates 112 may be provided with a plurality of side plates 112, which are sequentially connected to surround and connect the periphery of the bottom plate 111. The bottom plate 111 and the side plates 112 are arranged to form a receiving space 114 for receiving the rod 12, the support member 18 and the floating member 13. The receiving space 114 is also used to store cleaning water, and the water outlet 113 is arranged at a position of the side plate 112 close to the bottom plate 111. The mounting surface 1121 is arranged on the side of the side plate 112 facing away from the receiving space 114. The Hall sensor 15 is installed on the side of the side plate 112 facing away from the receiving space 114, which can reduce the risk of the Hall sensor 15 being damaged by the liquid in the receiving space 114. In some embodiments, the two support members 18 are connected to the bottom plate 111 and the side plate 112 provided with the Hall sensor 15, which is conducive to the cooperation between the Hall sensor 15 and the magnetic element 14, and is conducive to improving the structural strength of the water storage device 10. In some embodiments, the water storage container 11 further includes a cover 115 disposed on the side plate 112 . The cover 115 seals the accommodating space 114 to prevent liquid in the accommodating space 114 from leaking out, and can also provide protection for various components in the accommodating space 114 .

[0044] Combination Figure 3 and Figure 4 As shown, in some embodiments, a groove 124 is provided on one side of the rod 12 facing the float portion 132, and the groove 124 corresponds to the position of the float portion 132. When the float portion 132 rotates relative to the rod 12 until the float portion 132 contacts the rod 12, the float portion 132 is partially embedded in the groove 124. The groove 124 is provided without increasing the occupied space of the rod 12 and the float portion 132, and is also conducive to increasing the maximum rotation range of the float portion 132 relative to the rod 12, thereby facilitating the height that the water storage device 10 can sense and the water level detection range.

[0045] In some embodiments, the second end 122 of the rod 12 is provided with a receiving groove 1221, and the magnetic element 14 is received in the receiving groove 1221. The water storage device 10 further includes a sealing element 19, and the sealing element 19 includes but is not limited to rubber, etc. The sealing element 19 is provided on the magnetic element 14 and seals the receiving groove 1221. Providing the receiving groove 1221 to receive the magnetic element 14 is conducive to the installation and removal of the magnetic element 14 on the rod 12, thereby facilitating the maintenance of the magnetic element 14 and the rod 12, and the sealing element 19 can isolate the magnetic element 14 from the space in the water storage container 11, thereby achieving sealing and waterproof performance, and preventing the magnetic element 14 from being corroded and damaged.

[0046] In some embodiments, the water storage container 11 further includes a mounting shell 116 disposed on the side where the mounting surface 1121 of the side plate 112 is located, and the Hall sensor 15 is fixedly disposed in the mounting shell 116. The mounting shell 116 can provide protection and function for the Hall sensor 15. In some embodiments, the mounting shell 116 can also be provided with a sealant or other element to seal the mounting shell 116, so as to provide sealing and waterproof protection for the Hall sensor 15.

[0047] refer to Figure 3 As shown, in some embodiments, the magnetic element 14 has a south pole, a north pole, and a magnetic neutral line dividing the south pole and the north pole, and the magnetic neutral line is a virtual straight line located at the junction of the south pole and the north pole, and the magnetic neutral line is roughly parallel to the extension direction of the rod 12. When the extension direction of the rod 12 is perpendicular to the side plate 112 provided with the Hall sensor 15, the magnetic neutral line passes through the Hall sensor 15. It can be understood that when the rod 12 rotates relative to the water storage container 11 until the extension direction of the rod 12 is perpendicular to the side plate 112, the magnetic neutral line passes through the Hall sensor 15. At this time, the Hall value sensed by the Hall sensor 15 is zero. According to the water level corresponding to the floating member 13 at this position, when the magnetic field value sensed by the Hall sensor 15 is zero, the corresponding water level can be obtained.

[0048] Combination Figure 4 and Figure 5As shown, when the rod 12 rotates relative to the water storage container 11 until the magnetic neutral line is located on the side of the Hall sensor 15 facing the bottom plate 111, the magnetic pole value sensed by the Hall sensor 15 on the side of the magnetic neutral line facing away from the bottom plate 111 becomes larger, and when the rod 12 rotates relative to the water storage container 11 until the magnetic neutral line is located on the side of the Hall sensor 15 facing away from the bottom plate 111, the magnetic pole value sensed by the Hall sensor 15 on the side of the magnetic neutral line facing the floor becomes larger. Taking the case where the south pole is located on the side of the magnetic neutral line facing the bottom plate 111 and the north pole is located on the side of the magnetic neutral line facing away from the bottom plate 111 as an example, when the Hall sensor 15 senses that the north pole value becomes larger, it can be known that the water level is higher than the water level when the Hall value is zero, and when the Hall sensor 15 senses that the south pole value becomes larger, it can be known that the water level is lower than the water level when the Hall value is zero. According to the corresponding relationship between the specific value of the magnetic pole and the position of the floating member 13 and the rod 12, as well as the corresponding position of the floating member 13 and the rod 12 and the water level height, the water level in different states can be obtained to realize the global water level detection function.

[0049] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
