Description

Technical Field

[0001] This utility model relates to the field of automotive storage tank technology, specifically a detergent storage tank for automotive washers. Background Technology

[0002] Currently, car washers generally use a tank structure to store detergent liquid, and the liquid is delivered to the nozzles through a suction pipe located at the bottom of the tank to clean parts such as the windshield and headlights. To ensure cleaning effectiveness, the tank needs to maintain a stable liquid supply under various vehicle operating conditions and implement real-time monitoring of the liquid level.

[0003] In existing technologies, common detergent storage tanks typically employ a single-cavity structure, allowing liquid to flow freely within the tank. When a vehicle is undergoing rapid acceleration, deceleration, or turning, the liquid is prone to significant fluctuations and impacts within the tank, causing the bottom of the extraction pipe to be easily exposed to air. This results in problems such as poor extraction and intermittent spraying, affecting the stability of the washing function.

[0004] In liquid level detection, existing technologies generally employ float-type liquid level switches or electrode-type liquid level sensors for monitoring. However, because the liquid inside the storage tank is prone to fluctuations due to vehicle vibration, these sensors are often affected by liquid sloshing, leading to unstable detection signals or errors. For example, frequent triggering of the liquid level sensor during liquid fluctuations can cause falsely high or low monitoring results, making it difficult to accurately reflect the true liquid level and consequently affecting the timeliness of detergent replenishment or alarms.

[0005] In addition, some improved storage tanks have simple baffles or partitions installed inside to slow down the flow of liquid. However, these structures often only provide a barrier in one direction and cannot disperse liquid fluctuations in all directions, resulting in limited wave reduction effects and persistent problems such as unstable liquid levels and discontinuous pumping. Furthermore, the fabrication and installation of these baffles often increase structural complexity and cost, hindering large-scale applications.

[0006] In view of this, this paper studies and improves upon the existing problems, and provides a detergent storage tank for car washers to solve the current problems. The aim of this technology is to solve the problems and improve the practical value. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: a detergent storage tank for a car washer, comprising a tank body, a liquid extraction pipe, a sensing strip, a float guide pipe, and several sets of wave-damping columns. The tank body is used to store detergent liquid, the liquid extraction pipe extends to the bottom of the tank for extracting liquid, the sensing strip is disposed on the surface of the liquid extraction pipe, the float guide pipe is sleeved on the outside of the liquid extraction pipe and has a float core inside, and the wave-damping columns are installed at the bottom of the tank body to reduce liquid fluctuations.

[0009] In a preferred embodiment, several sets of wave-damping columns arranged in a matrix are fixedly installed inside the main body of the storage tank. Each set of wave-damping columns includes a core rod, a flow-suppressing column, and a flow-diverting column. The core rod, flow-suppressing column, and flow-diverting column are arranged vertically and fixed as a whole to the bottom surface of the main body of the storage tank. The flow-suppressing column and the flow-diverting column are arranged symmetrically on both sides of the core rod at the origin, thereby symmetrically dispersing liquid fluctuations during vehicle operation vibrations and reducing unidirectional impacts. Specifically, this structure can significantly reduce the intensity of liquid sloshing and ensure the stability of the pumping process.

[0010] In a preferred embodiment, the core rod is a one-piece solid column, with its bottom end fixedly connected to the bottom wall of the tank body and its top end extending freely upwards. Specifically, the core rod can provide initial obstruction and guidance when the liquid impacts, making the liquid flow direction more stable and further reducing the impact force of the liquid on the inner wall of the tank and the pumping pipe.

[0011] In a preferred embodiment, the flow-limiting column is a cylindrical structure with several corrugated flow-limiting grooves extending vertically on its outer circumferential surface. When liquid flows through the flow-limiting column, the corrugated flow-limiting grooves can change the liquid flow path and increase fluid friction, thereby reducing flow velocity and suppressing fluctuations. Specifically, this structure allows the liquid in the storage tank to be quickly buffered when the vehicle stops or accelerates suddenly, preventing large fluctuations in liquid level.

[0012] In a preferred example, the diversion column is an independent column with a rhomboid cross-section. A gap is maintained between the diversion column and the core rod and the flow-damping column, allowing the liquid flow to enter the channels between the diversion columns through the gap. Adjacent diversion columns are equidistantly distributed circumferentially, thus forming multiple liquid flow channels. Specifically, this structure enables the liquid flow to be uniformly dispersed, reducing concentrated liquid impact and improving the uniformity and stability of liquid flow inside the storage tank.

[0013] In a preferred embodiment, the spacing between the flow-limiting column and the flow-diverting column is set according to the volume of the storage tank body. When the storage tank volume is large, the spacing is appropriately increased to ensure that the liquid can be fully dispersed; when the storage tank volume is small, the spacing is reduced to enhance the flow-limiting effect. Specifically, this structure can adaptively adjust the liquid diversion and stabilization effect according to different storage tank specifications, ensuring liquid flow uniformity and storage tank applicability.

[0014] In a preferred embodiment, the bottom end of the extraction pipe extends to the bottom surface of the tank body, ensuring that the liquid can be fully extracted. A sensing strip, a Hall effect sensor structure, is provided on the outer surface of the extraction pipe, extending vertically along the pipe. A float tube is fitted around the extraction pipe, with both ends open and communicating with the inner cavity of the tank body. A magnetic float core is slidably installed inside the float tube, moving up and down with the liquid level and triggering the sensing strip through magnetic action to achieve real-time acquisition of the liquid level signal. Specifically, this structure not only ensures the accuracy of liquid level monitoring but also avoids interference from liquid fluctuations on the detection results.

[0015] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, by setting several sets of wave-damping columns inside the main body of the storage tank, and forming a synergistic effect of core rod, flow-suppressing column and flow-diverting column, the fluctuation and impact of liquid caused by vibration, sudden stop or acceleration during vehicle operation can be effectively reduced, so that the liquid level inside the storage tank remains relatively stable, thereby ensuring the continuity and stability of the liquid supply process at the liquid extraction pipe, and avoiding the problems of cavitation or poor liquid supply caused by liquid sloshing.

[0016] 2. In this invention, a Hall effect sensor strip is installed on the surface of the liquid extraction pipe, and a magnetic float that can slide up and down is installed inside the float guide tube. When the liquid level changes, the float rises and falls with the liquid and triggers the sensor strip, realizing real-time detection of the liquid level signal. Because the wave-damping column effectively suppresses liquid fluctuations, it avoids distortion of the liquid level signal due to liquid sloshing interference, thereby significantly improving the accuracy and reliability of liquid level monitoring and ensuring the normal operation of the car washer system.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a detergent storage tank for a car washer.

[0022] Combination Figures 1-4 As shown, this utility model provides a detergent storage tank for a car washer, including a tank body 100, a liquid extraction pipe 110, a sensing strip 120, a float guide tube 130, and several sets of wave-damping columns 200. Specifically, the tank body 100 is used to store detergent liquid, and a liquid extraction pipe 110 is provided inside it. A sensing strip 120 is embedded in the outer surface of the liquid extraction pipe 110, and the sensing strip 120 is used to collect signals of liquid level changes. A float guide tube 130 is provided on the outside of the liquid extraction pipe 110, and the float guide tube 130 is connected to the inner cavity of the tank body 100 to guide the raising and lowering of the float core 131. Several sets of wave-damping columns 200 are fixedly installed at the bottom of the tank body 100, and the wave-damping columns 200 are used to limit and divert the flow of liquid in the tank body 100.

[0023] Each set of wave-damping columns 200 includes a core rod 210, a flow-suppressing column 220, and a flow-diverting column 230. The core rod 210, flow-suppressing column 220, and flow-diverting column 230 are arranged vertically and are fixedly installed on the bottom surface of the inner cavity of the tank body 100. The flow-suppressing column 220 and flow-diverting column 230 are located on both sides of the core rod 210 and are arranged symmetrically at the origin to form a symmetrical liquid diversion effect, thereby reducing the intensity of liquid fluctuations and suppressing the liquid flow velocity.

[0024] In this embodiment, specifically, the core rod 210 is an integrally formed solid column structure, with its bottom end fixedly connected to the bottom wall of the tank body 100 and its top end extending freely upwards without contacting the liquid extraction pipe 110 or the floating guide pipe 130, for the purpose of initially blocking and guiding the liquid flow impact.

[0025] In this embodiment, the flow-limiting column 220 is a cylindrical structure with several corrugated flow-limiting grooves uniformly arranged on its outer circumferential surface extending vertically. Through these flow-limiting grooves, the liquid generates dispersion and frictional resistance when impacting the flow-limiting column 220, which can effectively reduce the flow velocity and limit the flow, thereby further reducing the amplitude of liquid sloshing.

[0026] In this embodiment, the diversion columns 230 are several independent pillars with a rhomboid cross-section. A gap is maintained between one side of the diversion column 230 and the core rod 210 and the flow-damping column 220, allowing the liquid to flow through this gap. Simultaneously, the multiple diversion columns 230 form equidistantly distributed liquid flow channels, uniformly dispersing the liquid as it passes through these channels, creating a stable diversion effect and ensuring the stability of the liquid flow within the tank body 100.

[0027] In this embodiment, the spacing between the flow-suppressing column 220 and the flow-diverting column 230 is set according to the volume of the tank body 100 and the flow characteristics of the liquid. When the volume of the tank body 100 is large, the spacing can be appropriately increased to ensure sufficient liquid diversion; when the volume of the tank body 100 is small, the spacing is reduced to enhance the flow-limiting effect of the liquid, thereby achieving uniform dispersion and stable flow of liquid in tank bodies 100 of different specifications.

[0028] In this embodiment, the bottom end of the extraction pipe 110 extends to the bottom surface of the inner cavity of the storage tank body 100, and is used to extract detergent liquid. The sensing strip 120 is a Hall effect sensor structure, extending vertically along the surface of the extraction pipe 110 in a strip shape, and is capable of sensing the displacement of the magnetic body. The float tube 130 is vertically sleeved on the outside of the extraction pipe 110, and both the upper and lower ends of the float tube 130 are open structures, communicating with the inner cavity of the storage tank body 100.

[0029] A float core 131 is slidably installed inside the float guide tube 130. The float core 131 is magnetic and can move up and down within the float guide tube 130 as the liquid level rises and falls within the tank body 100. The positional change of the float core 131 acts on the sensing strip 120 on the surface of the suction pipe 110, realizing real-time detection and output of the liquid level signal. Through the suppression of liquid fluctuations by the wave-damping column 200, the distortion of the liquid level detection signal caused by liquid sloshing can be effectively avoided, ensuring the accuracy of liquid level monitoring.

[0030] As can be seen from the above specific embodiments, this utility model combines the flow limiting and diversion function of the wave-damping column 200 with the liquid level detection function of the sensing strip 120, which can not only effectively reduce the sloshing of liquid in the main body 100 of the storage tank during vehicle operation and improve the stability of the pumping process, but also realize real-time and accurate monitoring of the liquid level, significantly improving the performance and reliability of the detergent storage tank for car washers.

[0031] Working principle and usage process of this utility model: This invention effectively reduces liquid fluctuations during vehicle operation by setting several sets of wave-damping columns 200 inside the main body 100 of the storage tank and utilizing the synergistic effect of the core rod 210, the flow-suppressing column 220 and the flow-diverting column 230 to limit and divert the liquid in the storage tank.

[0032] The core rod 210, serving as the central resistance structure, is fixedly connected to the bottom wall of the tank body 100, with its top extending freely upwards. It guides the liquid flow and acts as a diversion and energy-reducing mechanism during liquid impact. The flow-limiting column 220 is fitted around the core rod 210, with vertically extending corrugated flow-limiting grooves on its outer circumference. This limits the speed and reduces fluctuations in the liquid flow when it sloshes or impacts. The diversion column 230 has a rhomboid cross-section and maintains a gap with the core rod 210 and the flow-limiting column 220. The liquid flow is further evenly dispersed as it passes through the gap. Equidistantly distributed liquid flow channels are formed between adjacent wave-damping columns 200, achieving homogenization and stabilization of the liquid flow. The synergistic effect of these three structural components significantly reduces the impact and sloshing of the liquid in the tank under conditions of vehicle vibration, sudden stop, or acceleration, thereby maintaining the relative stability of the liquid level in the tank.

[0033] In terms of liquid level detection, this invention incorporates a strip-shaped sensing strip 120 embedded on the surface of the extraction pipe 110. This sensing strip is a Hall effect sensor structure. A float guide tube 130 is vertically positioned along the extraction pipe 110, and a magnetic float core 131 is slidably installed inside it. When the liquid level in the tank changes, the float core 131 moves within the float guide tube 130 as the liquid level rises and falls, triggering the sensing strip 120 at the corresponding position through magnetic force, thereby achieving real-time detection of the liquid level signal. Because the wave-damping column 200 suppresses liquid fluctuations, distortion or failure of the liquid level detection due to liquid sloshing is avoided, ensuring the accuracy and reliability of the monitoring data.

[0034] During use, the workflow of this utility model is as follows: Liquid storage: The detergent is injected into the main body of the storage tank 100, and the liquid freely enters the float pipe 130 and connects with the inner cavity of the storage tank.

[0035] Flow limiting and wave stabilization: When the vehicle is running, accelerating or braking suddenly, the liquid shock wave first acts on the core rod 210, then weakens the flow velocity through the flow limiting groove of the flow suppressing column 220, and finally disperses evenly through the diamond-shaped cross section of the flow dividing column 230, thereby reducing the wave intensity and stabilizing the liquid level.

[0036] Liquid level detection: As the liquid level rises and falls, the float 131 slides in the float guide tube 130, and the sensing strip 120 detects the magnetic signal of the float 131 in real time to realize the acquisition and output of liquid level signal.

[0037] Liquid extraction and supply: The bottom end of the extraction pipe 110 extends to the bottom of the storage tank body 100, which can directly extract stable liquid and deliver it to the car wash nozzle, ensuring the stability of the liquid supply process.

[0038] Through the above process, this utility model achieves comprehensive functions of liquid storage stabilization, wave prevention and flow suppression, and liquid level detection. It can maintain the continuity of detergent supply and the reliability of liquid level detection under vehicle operating conditions, significantly improving the performance and practical value of the storage tank.
