Description

Technical Field

[0001] The present application relates to the technical field of automobile coolant replacement, and particularly relates to a coolant recovery, cleaning and refilling device. Background Art

[0002] In the past, replacing automobile coolant was indeed a complex and time-consuming problem. The main reasons include that the thermostat cannot completely drain the original old coolant, the operation is inconvenient, time-consuming and laborious, the professional level is not high, and the pipeline system cannot be cleaned. During the replacement process, it is usually necessary to first drain the old coolant. This step requires opening the radiator cap and the drain valve to release the antifreeze. However, due to the presence of the thermostat, the old coolant is often difficult to be completely drained. In addition, the operation process requires ensuring that the water pump is in operation to completely drain the old coolant. This process is not only complex but also time-consuming. To clean the pipeline system, it is usually necessary to insert a distilled water pipe into the upper water inlet for flushing. Although this method can clean the pipeline to a certain extent, there are still limitations in that the old coolant cannot be completely removed. With the development of the automobile maintenance industry, the professional level has gradually improved. Modern automobile maintenance technology requires highly professional knowledge, and different automobile models and systems have different maintenance methods and requirements. In short, although there are many inconveniences and limitations in replacing automobile coolant in the past, with the progress of technology and the professional development of the maintenance industry, these problems are gradually being solved.

[0038] Refer to Figure 1The coolant recovery, cleaning and liquid adding device of the embodiment of the present application includes: a flushing tank 220, a new liquid tank 210, a recovery tank 230 and a valve body group, the recovery tank 230 is connected to the valve body group, and is used to recover the old liquid in the coolant tank, the flushing tank 220 is connected to the valve body group, and is used to circulate and clean the interior of the engine and the interior of the radiator water tank, and the new liquid tank 210 is connected to the valve body group, and is used to add new liquid to the engine and the radiator water tank.

[0039] In this embodiment, the old liquid inside the automobile coolant tank can be recycled first, and then the cleaning liquid can be pumped into the interior of the automobile coolant tank for cyclic cleaning and recycling, and finally the new coolant can be pumped into the interior of the automobile coolant tank to complete the recycling of the automobile coolant, the cleaning of the coolant tank and the filling of the coolant. The operation is simple, the cleaning and replacement are thorough, the working hours are reduced, and the work efficiency is improved. Specifically, the recovery tank 230 is a cavity structure, and by connecting with the valve body group and the pump body 370, the old coolant inside the automobile coolant tank can be recycled and the interior of the automobile coolant tank can be emptied. The cleaning tank 220 is connected to the valve body group and the pump body 370, and is connected to the interior of the automobile coolant tank through the liquid outlet pipe 310 and the liquid return pipe 320. After being discharged, the cleaning liquid is recycled and cyclic cleaning can be performed. The new liquid tank 210 is connected to the valve body group and the pump body 370, and the new coolant is pumped into the clean interior of the automobile coolant tank through the liquid outlet pipe 310.

[0040] Among them, the cross-sectional area of the shell 100 in the height direction gradually decreases from top to bottom, which optimizes the space utilization, and a control panel 1100 is cleverly extended from the front side of the shell 100. The layout is reasonable, and the operation interface is intuitive and easy to reach, which provides great convenience for the operator. The recovery tank is placed inside the shell 100 and is connected to the valve body group, which can recycle the old liquid from the coolant tank. The flushing tank 220 located above the recovery tank is also connected through the valve body group. It is used for circulating and cleaning the inside of the engine and the radiator water tank. It uses the cleaning liquid circulation mechanism to thoroughly remove the old liquid residue and impurities. The new liquid tank 210 is closely connected to the valve body group to add fresh liquid to the engine and the radiator water tank.

[0041] In a specific embodiment, it further includes: a control panel 400. The console 1100 is inclined and is inclined with the top of the housing 100. The inclination angle of the console 1100 is in the range of 45 degrees to 60 degrees. An installation groove for the control panel 400 is provided on the console 1100. The opening direction of the installation groove for the control panel 400 is inclined upward away from the housing 100. The control panel 400 is embedded inside the installation groove for the control panel 400 to control the start and stop of the valve body group. By setting the operation panel on the inclined console, the comfort and efficiency of the operator during use are ensured. With the inclination angle of the console 1100 set in the range of 45 degrees to 60 degrees, the best match between the operation interface and the operator's line of sight is achieved, which not only reduces the neck and back fatigue caused by long-term operation, but also makes various control buttons and display screens easier to reach and observe, greatly improving the operation convenience.

[0042] Among them, the installation groove for the control panel inclined upward away from the housing 100 ensures that the control panel 400 can be firmly embedded therein, avoiding operation errors caused by vibration or accidental touch. In addition, the inclined upward installation groove design also prevents liquid splashing or dust accumulation to a certain extent, further ensuring the stable operation and long service life of the control system. The control panel 400 itself is the core of the entire control system. Its internal integrates the precise control logic for key functions such as the start and stop of the valve body group. Through a simple and intuitive operation interface, the operator can easily achieve precise control of the coolant recovery, cleaning, and liquid addition processes, ensuring the efficiency and accuracy of the entire processing process.

[0043] In a specific embodiment, the cross-section of the front side panel of the housing 100 along the protruding direction is square, and the cross-sectional area gradually decreases along the protruding direction. The front side panel includes: a first front side plate 1130, a second front side plate 1110, a third front side plate 1120, and a fourth front side plate 1140. The first front side plate 1130, the second front side plate 1110, the third front side plate 1120, and the fourth front side plate 1140 are sequentially connected to form a convex structure. The plate surfaces of the first front side plate 1130 and the third front side plate 1120 are triangular, and the plate surface structures of the first front side plate 1130 and the third front side plate 1120 are the same, and are respectively connected to the side wall of the housing 100. The plate surfaces of the second front side plate 1110 and the fourth front side plate 1140 are both isosceles trapezoids, and the height of the fourth front side plate 1140 is greater than the height of the second front side plate 1110. The second front side plate 1110 is connected to the top of the housing 100, and the fourth front side plate 1140 is connected to the bottom of the housing 100. The installation groove for the control panel 400 is opened on the plate surface of the second front side plate 1110. Among them, the second front side plate 1110 is the protruding console 1100.

[0044] Specifically, the front panel of the housing 100, along its protruding direction, its cross section gradually evolves from a square, the area gradually decreases, and the front panel is exquisitely divided into four parts - the first front panel 1130, the second front panel 1110, the third front panel 1120 and the fourth front panel 1140, which are connected in sequence to form a convex structure. Among them, the panels of the first front panel 1130 and the third front panel 1120 are triangular and symmetrical to each other. The second and fourth front panels 1140 adopt an isosceles trapezoidal design to enhance the stability of the panel. The height of the fourth front panel 1140 is slightly higher than that of the second front panel 1110, so that the entire panel presents a transition in the vertical direction, which is perfectly integrated with the bottom and top of the housing 100. The mounting groove of the control panel 400 is set on the panel of the second front panel 1110, which improves the convenience of operation. The user can easily reach and operate the control panel without overstretching or adjusting the posture, which greatly improves the user experience.

[0045] In a specific embodiment, it also includes: a return pipe, a liquid outlet pipe, a drain pipe and a hook bracket. The drain pipe is connected to the recovery tank and passes through the shell 100 to discharge the old liquid in the recovery tank. The return pipe is connected to the recovery tank to recover the old liquid or cleaning liquid in the automobile coolant tank. The outlet pipe is connected to the new liquid tank 210 and the cleaning tank to discharge the new liquid or cleaning liquid to the interior of the automobile coolant tank. The hook bracket is arranged on the side wall of the shell 100 and is located on the same side of the shell 100 as the return pipe and the liquid outlet pipe. The cross-section of the hook bracket is at a right angle, one end is fixedly connected to the side wall of the shell 100, and the other end faces upward or downward and is spaced from the side wall of the shell 100 by a preset distance. There are two hook brackets, including a first hook bracket and a second hook bracket. The first hook bracket and the second hook bracket are arranged up and down, the first hook bracket is located above the second hook bracket, and the first hook is bent upward and the second hook is bent downward. The return pipe and the liquid outlet pipe are located between the first hook bracket and the second hook bracket.

[0046] In this embodiment, the drain pipe serves as the outlet of the recycling system and is directly connected to the recycling tank to ensure that the used liquid can be discharged smoothly and safely. The return pipe is responsible for effectively recycling the used liquid in the automotive coolant tank or the waste liquid generated during the cleaning process into the recycling tank. The liquid outlet pipe is cleverly connected to the new liquid tank 210 and the cleaning tank to ensure that fresh or clean liquid can be accurately conveyed into the interior of the automotive coolant tank. The setting of the hooks further optimizes the space utilization and improves the operation convenience. The device is specially designed with two hook brackets, namely the first hook bracket and the second hook bracket. These two brackets are respectively installed on the side walls of the housing 100. They are not only stable and reliable, but also fully consider the usage habits and needs of the operator. Moreover, the hook brackets have a right-angled cross-section. One end is tightly fixed on the side wall of the housing 100, and the other end is bent upward or downward according to actual needs, maintaining a certain preset distance from the side wall of the housing 100, which enhances the stability of the brackets and also provides support points for the return pipe and the liquid outlet pipe, avoiding the chaos of the pipelines. The first hook bracket is located above the second hook bracket, and they are bent upward and downward respectively, providing a more flexible and convenient layout scheme for the return pipe and the liquid outlet pipe.

[0047] In a specific embodiment, the new liquid tank 210 and the flushing tank 220 have the same structure, including a tank body, an upper cover, a lower cover, and a support rod.

[0048] In this embodiment, the tank body, as the core part of the liquid tank, is made of transparent glass material, which can provide a visual experience of a panoramic view of the internal space. Users can intuitively monitor the change in the liquid volume, effectively preventing the occurrence of overfilling or underfilling. At the same time, the selection of glass material effectively avoids the problem of liquid sticking to the tank wall during storage, ensuring the purity and quality of the liquid.

[0049] In this embodiment, both the upper cover and the bottom cover are made of high-strength, corrosion-resistant stainless steel or lightweight aluminum materials. The plate-like structure can match the top opening and the bottom opening of the tank body respectively for fixed sealing. Specifically, the upper cover and the bottom cover perfectly match the top and bottom of the tank body respectively. Through the design of increasing the cross-sectional diameter, the comprehensive coverage and tight sealing of both ends of the tank body are realized. The material selection of the upper cover and the bottom cover not only ensures the firm and durable structure, but also improves the overall sealing performance, effectively preventing the risk of liquid leakage. At the same time, this design also facilitates the user to perform the opening operation and subsequent maintenance work.

[0050] In this embodiment, the number of support rods is set to be more than two and they are vertically arranged inside the tank body. Their length is slightly longer than that of the tank body itself to ensure comprehensive support and stability of the tank body by means of bolt connection. The support rods are symmetrically arranged based on the central line of the tank body, enhancing the overall stability of the tank body. In addition, both ends of the support rods cleverly pass through the bottom cover and the upper cover and are tightly connected to them by means of bolt fixation, thus achieving a double-sealing effect on the top and bottom of the tank body.

[0051] Specifically, the number of support rods is four, symmetrically arranged with respect to the central axis of the tank body to form a square cross-section, and both ends of the four support rods respectively pass through the upper cover and the bottom cover and are then fixed by bolts. Among them, a liquid outlet through-hole is opened at the middle position of the bottom cover for connecting the pipeline of the device, and a liquid inlet through-hole is opened at the middle position of the top cover for adding liquid. A funnel with a screen structure is respectively provided at the liquid inlet through-hole position of the top cover of the new liquid tank 210 and the flushing tank 220 to facilitate filtration and prevent impurities from entering the interior.
