Description

Technical Field

[0001] The present disclosure relates to the technical field of induction water pumps, and in particular to an electronic water level induction pump. Background Art

[0002] A submersible pump generally consists of a pump body, a water pipe, a pump base, a submersible motor, and a starting protection device. Its primary function is to transfer water from one location to another, either by raising the water level or increasing the water pressure. The working principle of a submersible pump is that the motor drives the impeller to rotate at high speed, causing the liquid to be flung from the center of the impeller to the outer edges under centrifugal force. The liquid is decelerated and pressurized by the diffusion chamber before being discharged from the pump outlet. Simultaneously, a vacuum low-pressure zone is formed at the center of the impeller, allowing external liquid to be continuously replenished into the pump under atmospheric pressure, achieving continuous pumping. Submersible pumps have long been widely used in deep well water extraction, mine drainage, agricultural irrigation, industrial water circulation, urban water supply, and drainage engineering.

[0003] Nowadays, electronic induction submersible pumps are becoming more and more popular among the public. Electronic induction submersible pumps are usually equipped with two induction probes. Since the resistance value of water is much smaller than that of air, when the two induction probes are in contact with water, the resistance value between the two is less than the preset value K, the water pump will start. When the two induction probes leave the water, the resistance value between the two induction probes will increase. When the resistance value between the two is greater than or equal to the preset value K, the water pump will stop, thereby controlling the start and stop of the submersible pump.

[0004] Submersible pumps often need to work in water for a long time, which inevitably causes the roots of the sensor probes to be attached with a lot of water stains, microorganisms, metal salts and other substances that have a certain impact on the resistance value. This will cause a large error in the resistance value between the two sensor probes, causing the submersible pump to misjudge the start and stop, resulting in the submersible pump not being able to work normally. Utility Model Content

[0005] In view of the deficiencies or problems existing in the prior art, the present disclosure provides an electronic water level sensing pump with reliable operation.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: an electronic water level sensing pump, including a shell, on which a sensing component and an air storage chamber are provided, the sensing component includes a first sensing probe and several second sensing probes, the several second sensing probes are respectively connected to the first sensing probe, and one end of the first sensing probe is set in the air storage chamber.

[0007] As a preferred embodiment, a water level regulating portion is provided on the shell, and the water level regulating portion includes at least a first water level gear. The first water level gear is provided corresponding to one of the second sensing probes, and the two are provided at the same height.

[0008] As a preferred embodiment, the water level adjustment part also includes a water level selection gear, which is arranged above the first water level gear. The water level selection gear is provided with a plurality of adjustment parts for selecting the water level from bottom to top, and each adjustment part is provided with a corresponding second sensing probe, and each adjustment part and the corresponding second sensing probe are located at the same height.

[0009] As a preferred embodiment, a slot is provided on the side of the water level regulating part, the slot is an air storage cavity, a through hole is provided at the bottom of the slot, the first end of the first sensing probe is located in the through hole, and the second end extends out of the through hole.

[0010] As a preferred embodiment, the first sensing probe is at least partially located in the slot, and the depth of the slot is 2-3 cm.

[0011] As a preferred embodiment, the height of the first sensing probe is higher than the height of the first water level, and the height difference between the end of the second end of the first sensing probe and the first water level is at least 1 cm.

[0012] As a preferred embodiment, a water absorption component is further provided in the shell, and the water absorption component includes an impeller and a motor, and the motor drives the impeller to rotate.

[0013] As a preferred embodiment, a water inlet and a water outlet are further provided on the shell, the height of the water inlet is lower than that of the water outlet, water enters from the water inlet and flows out from the water outlet.

[0014] As a preferred embodiment, the first sensing probe and the second sensing probe are both resistance sensors.

[0015] Compared to existing products, since one end of the first sensing probe is positioned within the air storage chamber, substances that could affect the resistance value, such as water stains, microorganisms, and metal salts, are less likely to adhere to it. This significantly reduces false starts and stops due to resistance errors between the first and second sensing probes, making the induction pump more sensitive and reliable. It also reduces frequent starts and stops due to false starts, which extends the pump's service life to a certain extent. Furthermore, since the first sensing probe is free from corrosion from water stains, microorganisms, and metal salts, the first sensing probe also has a longer service life.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the present disclosure is described in detail, clearly, and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

[0024] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0025] Please see Figure 1 and Figure 4As shown, the present application provides an electronic water level sensing pump, comprising a shell 1, on which a sensing component and an air storage chamber 4 are provided, the sensing component comprising a first sensing probe 2 and several second sensing probes 3, the several second sensing probes 3 being respectively connected to the first sensing probe 2, the first sensing probe 2 and the second sensing probe 3 being both resistance sensors, one end of the first sensing probe 2 being provided in the air storage chamber 4, since there is air in the air storage chamber 4, when the induction pump enters the water to work, the end of the first sensing probe 2 located in the air storage chamber 4 is basically not exposed to a large amount of water immersion (except for occasional splashes of water on the first sensing probe 2), in this way, water stains, microorganisms, metal salts and other substances that affect the resistance value are not easily attached thereto, which will greatly reduce the misjudgment of pump startup and shutdown caused by the error in the resistance value between the first sensing probe 2 and the second sensing probe 3, thereby making the induction pump work more sensitive and reliable, and also reducing the frequent startup and shutdown of the pump due to misjudgment, which to a certain extent extends the service life of the pump. In addition, since there is no corrosion to the first sensing probe 2 by water stains, microorganisms, metal salts, etc., the service life of the first sensing probe 2 is also longer.

[0026] It should be noted that the electronic water level sensor pump itself is set with a preset value K, which is usually the resistance of air. When the sensor pump enters the water to work, a path is formed between the first sensor probe 2 and the second sensor probe 3. The resistance between the two is the resistance of the working medium, which is usually water. The resistance of water is much smaller than the resistance of air. If the resistance of the first sensor probe 2 and the second sensor probe 3 is less than the preset value K, the sensor pump starts working. Because one end of the first sensor probe 2 is set in the air storage chamber 4, it is not easy for water stains, microorganisms, metal salts and other substances that affect the resistance value to adhere to this end. After the sensor pump has worked for a period of time, the water level drops below the first sensor probe 2 and / or the second sensor probe 3 (that is, after the water level drops to the specified position), the resistance between the first sensor probe 2 and the second sensor probe 3 is equal to the resistance of air, and the sensor pump stops working. In this way, the sensor pump in the present application responds more sensitively and accurately to power on and off, and avoids damage to the sensor pump caused by continued operation after the water is pumped out.

[0027] Please continue to see Figure 1 and Figure 4As shown, in one embodiment of the present disclosure, a water level adjustment unit 5 is provided on the housing 1. Specifically, the water level adjustment unit 5 protrudes outward from the housing 1 and includes at least a first water level level. The first water level level is provided corresponding to one of the second sensing probes 3, and the two are arranged at the same height. The water level adjustment unit 5 also includes a water level selection level. The water level selection level is provided above the first water level level. From bottom to top, the water level selection level includes a plurality of adjustment members 6 for selecting the water level. Each adjustment member 6 is provided with a corresponding second sensing probe 3, and each adjustment member 6 is located at the same height as its corresponding second sensing probe 3. Specifically, the first water level level is located at the lower part of the housing 1 and below the water level selection level. When the water level drops below the second sensing probe 3 corresponding to the first water level level, the resistance between the second sensing probe 3 and the first sensing probe 2 is greater than or equal to a preset value K, and the induction pump shuts down. The first water level level and its corresponding second sensing probe 3 act as a safety mechanism, preventing the induction pump from erroneously shutting down due to an error in the resistance between the first and second sensing probes 2 and 3. Adjustment members 6 are buttons, each corresponding to a different water level. When you press an adjustment member 6 at a different height, the corresponding second sensor probe 3 senses the resistance between it and the first sensor probe 2. If the resistance between the two is less than K, the induction pump begins operating. When the resistance between the two reaches K or greater, the induction pump stops, pumping the water to the desired height. It should be understood that the number of second sensors should be the sum of the number of adjustment members 6 and the number of first water level levels.

[0028] Please also refer to Figure 2 As shown, further, a slot is provided on the side of the water level regulating portion 5, and the slot serves as an air storage chamber 4. A through hole is provided at the bottom of the slot, and the first end of the first sensing probe 2 is located in the through hole, and the second end extends out of the through hole. The first sensing probe 2 is at least partially located in the slot, and the depth of the slot is 2-3 cm. Specifically, the air storage chamber 4 is provided at the lower left corner or lower right corner of the water level regulating portion 5. The slot is a semi-enclosed structure, and a notch is provided on the side. The notch includes an upper edge and a side edge. The distance between the upper edge and the bottom of the slot is the depth of the slot, which is 2-3 cm. In this way, at least 2-3 cm of the first sensing probe 2 is provided in the air storage chamber 4.

[0029] Furthermore, the height of the first sensing probe 2 is higher than the height of the first water level, and the height difference between the end of the second end of the first sensing probe 2 and the first water level is at least 1 cm. This arrangement ensures that the first water level is located below the first sensing probe 2 to provide protection.

[0030] like Figure 1 and Figure 3As shown, in one embodiment of the present disclosure, a water suction component is further provided in the shell 1, and a water inlet 8 and a water outlet 9 are also provided on the shell 1. The height of the water inlet 8 is lower than the height of the water outlet 9. Water enters from the water inlet 8 and flows out from the water outlet 9. The water suction component includes an impeller and a motor. The motor drives the impeller to rotate, thereby forming suction in the pump body to suck the liquid into the pump body from the water inlet 8.

[0031] The present application has been described in detail above. Specific examples have been used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application and its core concepts. It should be noted that, without departing from the principles of the present application, a number of improvements and modifications may be made to the present application by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present application.
