Description

Technical Field

[0001] The present invention relates to a water level sensor and a water container bottle mouth mating device. Background Art

[0002] There are many existing methods for detecting and controlling the water level of a water tank, and most of them use a float switch to detect the water level. The float switch consists of a reed switch and a magnetic ring float. When the water tank is empty, the magnetic ring float sinks away from the reed switch, and the reed switch is disconnected; when the water tank is full of water, the magnetic ring float floats close to the reed switch, and the reed switch is closed. By detecting the open or closed state of the reed switch, it can be judged whether there is water at the position where the float switch is located. However, the existing float switches still have the following deficiencies: (1) When multiple water levels need to be detected, the number of float switches needs to be increased accordingly. Generally, one float switch corresponds to one water level. (2) In addition, due to the large volume, high cost of the float switch, and the presence of many gaps that cannot be cleaned, resulting in sanitary dead corners. On the other hand, the moving float is easily affected by foreign objects in the water (such as scale), causing jamming and inability to move, resulting in failure. (3) Moreover, when more water levels need to be detected, multiple float switches need to be installed. The installation is complex, and the water tank has many openings, which are prone to leakage and are more difficult to clean. (4) The float (especially the steel ball and the magnet inside it) is relatively heavy. When there is not enough water to make the float float, there will still be a certain amount of water in the water tank, resulting in remaining water, which will cause the newly added water to be polluted and become bacteria-infected and not fresh, which will lead to non-drinkability or non-usability. Summary of the Invention

[0003] The present invention provides a water level sensor and its water container bottle mouth mating device, which can set multiple water level electrodes, continuously monitor the water storage volume, is easy to install and disassemble, can accurately detect the water level, and can extract the remaining water volume.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A water level sensor, characterized in that it includes a mounting base, an upper cover, a circuit board, a common electrode, and a water level electrode. A plurality of through holes for the water level electrode and the common electrode to extend downward are provided on the mounting base. The circuit board is arranged on the top surface of the mounting base. One end of the common electrode and the water level electrode is connected to the water level signal circuit board, and the other end extends downward along the through hole for detecting the water level at at least one height. The upper cover is arranged on the top of the mounting base and covers the circuit board. A water absorption hole is provided on the mounting base. The lower end of the water absorption hole is used to connect a water suction pipe for extracting the stored water in the container. The upper end of the water absorption hole is provided with a water pipe joint, and the extended end of the water pipe joint extends upward through the upper cover for connecting a water pumping pipeline; a connecting device for directly or indirectly connecting with a matching water container is provided on the outer wall of the bottom of the mounting base.

[0006] Furthermore, a card slot is provided on the top outer wall of the mounting seat, and a convex strip corresponding to the card slot is provided on the inner wall of the upper cover. The upper cover and the mounting seat are connected by the convex strip and the card slot correspondingly, forming a detachable structure of the upper cover and the mounting seat.

[0007] Furthermore, the number of the water level electrodes is 1, 2, 3, 4 or more.

[0008] Furthermore, the connecting device is a hollow tube with external threads.

[0009] Furthermore, the hollow tube is plugged into the center of a water container bottle mouth matching device for detachable connection with a water container provided with a bottle mouth.

[0010] Furthermore, a wired or wireless signal output port for transmitting and outputting the water level signal is provided on the circuit board or on the top of the upper cover; there are at least two water level electrodes, including an electrode for detecting the lowest water level and an electrode for detecting the highest water level.

[0011] Furthermore, a pressing rib for pressing the circuit board is provided on the inner wall of the upper cover.

[0012] Furthermore, the water suction hole is arranged in the middle part of the mounting seat, and the lower end of the water suction hole is detachably or fixedly connected with a water suction pipe for extracting water stored in the container, and the upper end of the water suction hole is provided with a water pipe joint, and the extended end of the water pipe joint extends upward through the upper cover for connecting the water pumping pipe.

[0013] Furthermore, the water pipe joint and the mounting seat are integrally formed.

[0014] Furthermore, it also includes a positioning platform, a limiting groove and a limiting block. The positioning platform is sleeved on the lower part of the water pipe joint, the limiting groove is symmetrically arranged on the lower end of the positioning platform, and the limiting block is arranged on the inner surface of the top of the upper cover and corresponds to the limiting groove.

[0015] Furthermore, a wedge-shaped boss for reinforcing the connection between the water pipe and the water pipe joint is provided on the upper part of the water pipe joint, and the diameter of the wedge-shaped boss gradually increases from top to bottom.

[0016] Furthermore, the water suction pipe is a hard water suction pipe, a soft water suction pipe or a combination of a soft water suction pipe and an anti-floating heavy end.

[0017] The present invention also provides a water container bottle mouth matching device used in conjunction with the above-mentioned water level sensor, which is entirely made of silicone material and includes a top panel, in the middle of which is provided a hollow outer corrugated tube for receiving a connecting device of the water level sensor.

[0018] Compared with the existing water level sensors, the beneficial effects of the present invention are as follows. Through the water absorption holes, water suction pipes and water pipe connectors on the mounting base, during installation, it can be directly installed at the opening of a water tank or a water bucket (especially bottled water with a standard bottle mouth), without the need to set installation holes at other positions, which is convenient for installation and use. Moreover, the water suction pipe is a combination of a rigid water suction pipe or a flexible water suction pipe and an anti-floating heavy end, so it will not be unable to reach the bottom of the water tank or water bucket due to the buoyancy force in the water tank or water bucket (water bottle). The combination of the water suction pipe and the lowest water level electrode is close to the bottom of the water tank or water bucket, so that the water can be pumped out completely every time, ensuring that the added water will not be contaminated and remains fresh, which is difficult to achieve with other water level sensors; the number of water level electrodes can be set according to needs to continuously monitor the water level.
