The low water level warning device usually includes mechanical parts and electronic parts, which may wear and age during long-term use. In particular, electronic components that have been immersed in the water tank for a long time are more susceptible to moisture and aging. These problems make the low water level warning device in the water tank easy to be damaged. At the same time, if the water level warning device is installed in an improper position, it may cause water waves in the water tank, affecting the accuracy of the warning device, or causing the device to be submerged in water and unable to sound an alarm.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model provides Figure 1-5 A low water level warning device for a stainless steel water tank is shown, comprising a box body 1, a signal receiver 3 is arranged on the upper part of one end of the box body 1, a magnet sensor 5 is fixedly installed on the lower part of one end of the box body 1, a guide cylinder 6 is arranged on the inner wall of one end of the box body 1, and there is a gap between the lower end of the guide cylinder 6 and the bottom inner wall of the box body 1, and the distance of the gap is greater than the size of the magnetic steel float 7, so that the magnetic steel float 7 is placed in the guide cylinder 6 from the gap;

[0025] A spring 8 is provided at the bottom of one end of the interior of the box body 1. The spring 8 is made of stainless steel material, which makes it corrosion-resistant and elastic, and can maintain elasticity for a long time, thereby extending its service life. The spring 8 is located at the lower end of the magnetic steel float 7. Since there is a gap between the lower end of the guide cylinder 6 and the bottom of the box body 1, when the magnetic steel float 7 drops to the lowest water level inside the box body 1, the spring 8 prevents the magnetic steel float 7 from falling out from the gap. A base 9 is fixedly installed at the bottom of the spring 8. The base 9 is fixedly installed at the bottom of one end of the interior of the box body 1. The magnetic steel float 7 is provided inside the guide cylinder 6.

[0026] Furthermore, in the above technical solution, the top and back of the guide cylinder 6 are mesh hollow structures, the cross-section of the guide cylinder 6 is a U-shaped structure, the two ends of the front side of the guide cylinder 6 are fixedly mounted on the inner wall of one end of the box body 1, and the bottom of the guide cylinder 6 is a hollow structure. The guide cylinder 6 adopts a mesh hollow structure and a U-shaped structure, which can effectively prevent water ripples and can also synchronize the internal water level of the guide cylinder 6 with the water level in the water tank, thereby improving the accuracy of the warning device.

[0027] Furthermore, in the above technical solution, a sleeve 4 is fixedly installed at one end of the box body 1, and a connecting portion 31 is provided on the back of the signal receiver 3. There is a notch between the connecting portion 31 and the back of the signal receiver 3. The signal receiver 3 is inserted into the sleeve 4 through the connecting portion 31, so as to facilitate the installation and disassembly of the signal receiver 3 outside the box body 1.

[0028] Furthermore, in the above technical solution, a warning light 32 is fixedly installed on the top of the signal receiver 3. The warning light 32 adopts a high-brightness LED lamp bead, which can emit strong light in a short time to effectively remind the user. A wire 51 is connected to the top of the magnetic sensor 5, and the upper end of the wire 51 is electrically connected to the component below the signal receiver 3, so that the magnetic sensor 5 can transmit the signal to the signal receiver 3.

[0029] Furthermore, in the above technical solution, a top end of the box body 1 is covered with a top cover 2, and a rear end of the top cover 2 is movably connected to a top end of the box body 1 through a hinge. A water inlet pipe 10 is fixedly installed at one end of the box body 1 and located on one side of the magnetic sensor 5. The water inlet pipe 10 is made of stainless steel to prevent rust and water pollution.

[0030] Furthermore, in the above technical solution, the diameter of the magnetic steel float 7 is larger than the diameter of the spring 8, so when the magnetic steel float 7 drops to the lowest position, the magnetic steel float 7 is prevented from being stuck in the spring 8. The position of the magnetic sensor 5 corresponds to the position of the guide tube 6, and the magnetic sensor 5 is located at the lowest water level of the box 1.

[0031] The low water level warning device for a stainless steel water tank provided by the utility model has the following working process when in use:

[0032] Install the guide cylinder 6, magnetic steel float 7, spring 8 and other components on the inner wall and outer wall of the same end of the box body 1, and then insert the connecting part 31 set on the back of the signal receiver 3 into the ferrule 4. To maintain the stability of the signal receiver 3, the connecting part 31 can be connected and fixed with the ferrule 4 by bolts. At the same time, install the magnetic sensor 5 at the bottom of one end of the box body 1, and the position of the magnetic sensor 5 corresponds to the position of the guide cylinder 6. At the same time, the installation position of the magnetic sensor 5 is the lowest water level position of the box body 1. After these components are installed, cover the top cover 2 on the box body 1, and connect the external water supply device to the water inlet pipe 10;

[0033] When the water level in the box body 1 drops to a certain level, the magnetic steel float 7 will rise and fall in the guide cylinder 6 as the water level rises and falls. When the magnetic steel float 7 drops to the lowest water level, it will be sensed by the magnetic sensor 5 outside the box body 1. Then the magnetic sensor 5 transmits the signal to the signal receiver 3, and the signal receiver 3 converts it into an electrical signal. After the electrical signal is processed by the components inside the signal receiver 3, it will trigger the warning light 32 to sound an alarm, reminding the user that the water level has reached a low water level and that water needs to be added in time. When the box body 1 is refilled with water, the magnetic steel float 7 starts to float again, and then the magnetic steel float 7 starts to move away from the magnetic sensor 5, and then the magnetic sensor 5 cannot sense the magnetic steel float 7, then the signal is disconnected, and then the signal receiver 3 cannot receive the signal, and then the warning light 32 stops buzzing and alarming.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
