Description

Technical Field

[0001] This utility model relates to the field of electronic drain valve technology, specifically to an electronic drain valve with a liquid level sensing structure. Background Technology

[0002] An electronic drain valve is a valve that can automatically open and close to drain water. In existing technology, two sets of probes, one red and one blue, are installed on the electronic drain valve. By adjusting the position and height of the two sets of probes, the valve can be opened at the corresponding liquid level to achieve drainage.

[0003] However, most existing probes are open-type. When the container is made of metal, the probe will make inaccurate measurements due to the interference of the inner wall of the container, which will affect the device's judgment of water level.

[0004] Therefore, in order to solve the above problems, an electronic drain valve with a liquid level sensing structure is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an electronic drain valve with a liquid level sensing structure to solve the problem mentioned in the background art that most of the probes in the prior art are open-type. When the container is made of metal, the probe will cause inaccurate measurement results due to the interference of the inner wall of the metal when it comes into contact with the container, which will affect the device's judgment of water level.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electronic drain valve with a liquid level sensing structure, comprising: a controller, an electronic valve disposed on the bottom surface of the controller, wires and plugs disposed on the left and right side walls of the controller respectively, a probe disposed at the bottom end of the wires, and a counterweight disposed on the outer side of the bottom end of the wires;

[0007] The top surface of the counterweight is integrally formed with a threaded block;

[0008] A protective structure is installed on the threaded block. The protective structure includes an upper protective shell, which is movably installed on the outside of the probe. A threaded sleeve is integrally formed on the top surface of the upper protective shell. A slot is formed on the surface of the upper protective shell. A lower protective shell is fixedly connected to the bottom surface of the upper protective shell by threads. A through hole is formed on the surface of the lower protective shell.

[0009] Preferably, the threaded sleeve is fixedly installed on the outer side of the upper end of the threaded block by threads, and the outer diameter of the threaded block is larger than the diameter of the wire.

[0010] Preferably, the surface of the threaded sleeve is also provided with a groove, the width of which is greater than the diameter of the wire.

[0011] Preferably, the upper and lower protective shells are spherical and are fitted onto the outside of the probe.

[0012] Preferably, the surface of the upper protective shell is also provided with through holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by setting a protective structure on the outside of the probe, the upper protective shell and the lower protective shell can shield and protect the probe from the outside. When in use, the probe can be isolated to a suitable position on the outside of the inner wall of the metal container, avoiding direct contact between the probe and the inner wall of the metal container, reducing the influence of the metal container on the water level measurement, and thus ensuring the normal use of the device.

[0014] This invention features a protective structure. The upper protective shell is fitted over the outside of the wire via a slot. Moving the upper protective shell allows it to fit over the outside of the probe, with the threaded sleeve contacting the threaded block. Rotating the threaded sleeve allows it to be threaded onto the outside of the threaded block, at which point the upper protective shell can fit over the outside of the probe. The lower protective shell is threaded onto the bottom surface of the upper protective shell and can be fixedly connected to it. The lower protective shell can also fit over the outside of the probe. Two sets of probes are installed at different heights inside the container. Water can enter and exit through the through-hole and slot within the upper and lower protective shells, allowing the probes to be immersed in water or kept away from the water source, enabling different operations. Furthermore, the lower protective shell, in conjunction with the upper protective shell, can shield the probe from the outside. When used inside a metal container, it keeps the probe away from the inner wall of the metal container, maintaining a safe distance and preventing direct contact. This reduces the impact of the metal container on water level measurement, ensuring normal operation of the device and improving its practicality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 The present invention provides an embodiment of an electronic drain valve with a liquid level sensing structure:

[0022] The controller 1, electronic valve 11, wire 12, probe 13, counterweight 14 and plug 16 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] An electronic drain valve with a liquid level sensing structure includes: a controller 1, an electronic valve 11 on the bottom surface of the controller 1, wires 12 and plugs 16 on the left and right side walls of the controller 1 respectively, a probe 13 at the bottom end of the wires 12, and a counterweight 14 on the outer side of the bottom end of the wires 12.

[0024] The top surface of the counterweight 14 is integrally formed with a threaded block 15;

[0025] A protective structure 2 is installed on the threaded block 15. The protective structure 2 includes an upper protective shell 21, which is movably installed on the outside of the probe 13. A threaded sleeve 22 is integrally formed on the top surface of the upper protective shell 21. A slot 23 is opened on the surface of the upper protective shell 21. A lower protective shell 24 is fixedly connected to the bottom surface of the upper protective shell 21 by threads. A through hole 25 is opened on the surface of the lower protective shell 24. By setting the protective structure 2 on the outside of the probe 13, the upper protective shell 21 and the lower protective shell 24 can shield and protect the probe 13 from the outside. During use, the probe 13 can be isolated to a suitable position on the outside of the inner wall of the metal container, avoiding direct contact between the probe 13 and the inner wall of the metal container, reducing the influence of the metal container on the water level measurement, and thus ensuring the normal use of the device.

[0026] Furthermore, the threaded sleeve 22 is fixedly installed on the outer side of the upper end of the threaded block 15 by threads. The outer diameter of the threaded block 15 is larger than the diameter of the wire 12. The threaded sleeve 22 is easy to install on the outer side of the threaded block 15. The threaded sleeve 22, together with the threaded block 15, can fix the protective structure 2 on the outer side of the probe 13 to ensure that the probe 13 is in a relatively centered position between the upper protective shell 21 and the lower protective shell 24.

[0027] Furthermore, the surface of the threaded sleeve 22 is also provided with a slot 23. The width of the slot 23 is greater than the diameter of the wire 12. The upper protective shell 21 and the threaded sleeve 22 can be fitted onto the outside of the wire 12 through the slot 23, so that the upper protective shell 21 can be moved on the wire 12 to fit onto the outside of the probe 13.

[0028] Furthermore, the upper protective shell 21 and the lower protective shell 24 form a spherical shape and are fitted on the outside of the probe 13. The upper protective shell 21 and the lower protective shell 24 can provide all-round protection for the probe 13 from the outside, which can ensure that the probe 13 maintains an appropriate distance from the inner wall of the metal container, avoid direct contact between the probe 13 and the inner wall of the metal container, reduce the influence of the metal container on the water level measurement, and ensure the accuracy of the device.

[0029] Furthermore, the surface of the upper protective shell 21 is also provided with through holes 25, which provide conditions for the flow of water source inside and outside the upper protective shell 21 and the lower protective shell 24, so that the probe 13 can be immersed in water or away from the water source to realize different operations of the device.

[0030] Working principle: During installation, the upper protective shell 21 is fitted onto the outside of the wire 12 through the slot 23. Then, the upper protective shell 21 is moved so that it is fitted onto the outside of the probe 13, and the threaded sleeve 22 will contact the threaded block 15. By rotating the threaded sleeve 22, the threaded sleeve 22 can be installed on the outside of the threaded block 15 through the thread. At this time, the upper protective shell 21 can be fitted onto the outside of the probe 13. The lower protective shell 24 is installed on the bottom surface of the upper protective shell 21 through the thread. The lower protective shell 24 can be fixedly connected to the upper protective shell 21, and the lower protective shell 24 can also be fitted onto the outside of the probe 13.

[0031] In use, the two sets of probes 13 are installed at different heights inside the container. Water can enter and exit through the through hole 25 and the empty groove 23 within the upper protective shell 21 and the lower protective shell 24, allowing the probes 13 to be immersed in water or kept away from the water source, thus enabling different operations of the device. Furthermore, the lower protective shell 24, in conjunction with the upper protective shell 21, can shield and protect the probes 13 from the outside. When used inside a metal container, the probes 13 can be kept away from the inner wall of the metal container, maintaining a safe distance between them and avoiding direct contact. This reduces the impact of the metal container on water level measurement, ensuring the normal use of the device and improving its practicality.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
