Description

Technical Field

[0001] This utility model relates to the technical field of car washing, and in particular to a washing device. Background Technology

[0002] In automotive equipment maintenance, fuel injectors are critical components, and their proper functioning and cleanliness have a significant impact on the performance of automotive equipment. Therefore, cleaning fuel injectors is an essential step in ensuring the efficient and stable operation of automotive equipment.

[0003] However, in existing fuel injector cleaning equipment, the pump assembly is installed inside the reservoir. This constant immersion in the cleaning fluid makes the pump assembly prone to corrosion and damage. Furthermore, the filter is typically located outside the reservoir, and the pump assembly is connected to both the reservoir and the filter. The cleaning fluid in the reservoir passes through the pump assembly before being filtered, allowing impurities in the cleaning fluid to directly enter the pump assembly and damage it.

[0040] like Figures 1 to 3As shown, in some embodiments, a cleaning device includes a storage tank 100, a filter 200, and a pump assembly 300. The filter 200 is connected to the storage tank 100 and is disposed outside the storage tank 100. One end of the pump assembly 300 is connected to the filter 200, and the other end of the pump assembly 300 is used to connect to a nozzle 400. The pump assembly 300 is disposed outside the storage tank 100 and is used to draw cleaning fluid from the storage tank 100 through the filter 200 to the nozzle 400 for cleaning the nozzle 400.

[0041] The pump assembly 300 is located outside the storage tank 100, thus avoiding corrosion from the cleaning fluid inside the storage tank 100. Furthermore, the cleaning fluid in the storage tank 100 passes through the filter 200 before passing through the pump assembly 300, reducing the amount of impurities in the cleaning fluid entering the pump assembly 300 and minimizing the impact of damage. This cleaning equipment primarily utilizes the power generated by the pump assembly 300 to achieve the circulation and filtration of the cleaning fluid. When the pump assembly 300 is operating, the cleaning fluid in the storage tank 100 is drawn out under the suction force of the pump assembly 300. The cleaning fluid first passes through the filter 200, which is connected to and located outside the storage tank 100. The filter 200 intercepts and filters impurities and particulate matter in the cleaning fluid, purifying it. The filtered cleaning fluid is then transported by the pump assembly 300 to the nozzle 400, where it cleans the nozzle 400.

[0042] In some embodiments, the storage tank 100 serves as a container for the cleaning fluid. The storage tank 100 may have a rectangular structure.

[0043] Specifically, the reservoir 100 can be an oil tank. The cleaning fluid can be oil. The nozzle 400 can be a fuel injector. The pump assembly 300 can be an oil pump. That is, this cleaning equipment can be used to clean fuel injectors.

[0044] Specifically, the pump assembly 300 can be a roller pump oil pump, which can draw oil without contacting the oil, allowing the pump assembly 300 to be located outside the reservoir 100.

[0045] In some embodiments, the cleaning equipment includes a housing 500 and a support frame 600, the housing 500 having a receiving space, and the liquid storage tank 100, filter 200, pump assembly 300 and support frame 600 being housed in the receiving space.

[0046] It should be noted that the housing 500 encloses components such as the liquid storage tank 100, filter 200, and pump assembly 300 within the containment space, providing protection and preventing external dust, debris, moisture, etc., from entering the containment space, thus avoiding damage to the components within the containment space or affecting their normal operation.

[0047] Specifically, the support frame 600 is fixedly connected to the housing 500, and the filter 200 and pump assembly 300 are connected to and disposed on the support frame 600. The support frame 600 fixes the filter 200 and pump assembly 300 within the accommodating space of the housing 500.

[0048] Specifically, the support frame 600, the liquid storage tank 100, the filter 200 and the pump assembly 300 are all located at the bottom of the accommodating space.

[0049] It should be noted that the liquid storage tank 100, filter 200, and pump assembly 300 are typically heavy components. By placing the liquid storage tank 100, filter 200, pump assembly 300, and support frame 600 together at the bottom of the accommodating space, the center of gravity of the entire cleaning equipment is lowered, thereby improving its stability. For example, during operation, even if subjected to external forces such as slight vibrations or collisions, the cleaning equipment is less likely to tip over or shake, thus ensuring its stability and safety during operation.

[0050] Specifically, the storage tank 100 can be installed on the bottom plate 510 of the housing 500. Since the storage tank 100 also contains cleaning fluid during use, this arrangement can effectively improve the stability of the cleaning equipment. Furthermore, the upper part of the tank 100 can be connected to a filling port, and the bottom of the tank 100 can be provided with a settling tank. The bottom surface of the settling tank can be provided with a drain port to facilitate the replacement of the cleaning fluid, reduce sedimentation impurities at the bottom of the tank 100, and thus effectively prevent sedimentation impurities from damaging the pump assembly 300. Further, the bottom plate of the housing 500 can be provided with a drain hole corresponding to the settling tank. The tank wall of the settling tank protrudes beyond the drain hole, making the horizontal position of the tank wall lower than other parts of the storage tank 100. Under the action of gravity, the cleaning fluid will carry the sedimentation impurities out through the drain hole.

[0051] In some embodiments, the support frame 600 includes a first step structure 610 and a second step structure 620, the first step structure 610 and the second step structure 620 are connected and arranged in a stepped manner, the filter 200 is connected to and disposed on the first step structure 610, and the pump assembly 300 is connected to and disposed on the second step structure 620, such that the filter 200 and the pump assembly 300 are located at different heights.

[0052] Specifically, the height of the first step structure 610 is lower than the height of the second step structure 620. That is, the installation height of the filter 200 is lower than the installation height of the pump assembly 300. Installing the filter 200 and the pump assembly 300 on the first step structure 610 and the second step structure 620 at different heights reduces the mutual influence between them. For example, the pump assembly 300 may vibrate during operation. If the filter 200 and the pump assembly 300 are installed on the same plane, the vibration of the pump assembly 300 may affect the filtration effect of the filter 200, or even cause the filter element inside the filter 200 to loosen or be damaged. Using the first step structure 610 and the second step structure 620 at different heights effectively isolates the transmission of this vibration, ensuring that the filter 200 and the pump assembly 300 operate independently and stably.

[0053] Specifically, the pump assembly 300 can be connected to a fault sensor and an alarm. The fault sensor can be located on the second step structure 620 and is used to detect the real-time status information of the pump assembly 300, including but not limited to the vibration or noise generated by the pump assembly 300. When the vibration or noise level of the pump assembly 300 is detected to be outside the preset range, the alarm will receive the electrical signal emitted by the fault sensor and issue an alarm.

[0054] In some embodiments, the cleaning device includes a U-shaped tube 700, one end of which is connected to a filter 200 and the other end of which is connected to a pump assembly 300.

[0055] It should be noted that the U-shaped tube 700 connects the filter 200 and the pump assembly 300 at different heights. When the pump assembly 300 is operating, it generates a pressure difference, causing the cleaning fluid to flow from the filter 200 through the U-shaped tube 700 to the pump assembly 300. Due to the special shape of the U-shaped tube 700, it can accommodate the height difference between the filter 200 and the pump assembly 300, ensuring smooth flow of the cleaning fluid between the filter 200 and the pump assembly 300 at different heights.

[0056] In some embodiments, the first step structure 610 is a first L-shaped plate, the second step structure 620 is a second L-shaped plate, one end of the first L-shaped plate is connected to the housing 500, the other end of the first L-shaped plate is connected to one end of the second L-shaped plate, and the other end of the second L-shaped plate is connected to the housing 500.

[0057] It should be noted that the shapes of the first and second L-shaped plates can make full use of the internal space of the housing 500, especially the accommodating space at the bottom of the housing 500. By connecting the first and second L-shaped plates in a stepped manner, mounting planes of different heights can be formed in the vertical direction, providing suitable mounting positions for the filter 200 and the pump assembly 300, avoiding mutual interference between the filter 200 and the pump assembly 300, and making the internal layout of the cleaning equipment more compact and reasonable.

[0058] Specifically, the first L-shaped plate includes a first connecting plate 611 and a first supporting plate 612. One end of the first connecting plate 611 is connected to the housing 500, and the other end is connected to one end of the first supporting plate 612. The other end of the first supporting plate 612 is connected to the second L-shaped plate. The first supporting plate 612 is used to support the filter 200, and the first supporting plate 612 is set in a horizontal direction (i.e., perpendicular to the direction of gravity during use). The horizontal setting of the first supporting plate 612 provides a flat and stable support surface for the filter 200, allowing the filter 200 to be firmly installed on it. During the operation of the cleaning equipment, the filter 200 may be subjected to external forces such as the impact of the cleaning fluid and the vibration of the pump assembly 300. However, due to the stable support of the first supporting plate 612, the filter 200 can maintain a fixed position, avoiding the impact of shaking or displacement on the filtration effect, thereby ensuring the normal operation of the cleaning equipment.

[0059] Specifically, the first connecting plate 611 can be set in the vertical direction (i.e., the direction of gravity during use).

[0060] Specifically, the cleaning equipment also includes a first fixing member 810. The first fixing member 810 is arranged around the outer periphery of the filter 200, and its two ends are respectively fixedly connected to the first support plate 612. The first fixing member 810 can stably fix the filter 200 to the first support plate 612.

[0061] Specifically, the second L-shaped plate includes a second connecting plate 621 and a second support plate 622. One end of the second support plate 622 is connected to the housing 500, and the other end is connected to one end of the second connecting plate 621. The other end of the second connecting plate 621 is connected to the first L-shaped plate. The second support plate 622 is used to support the pump assembly 300, and the second support plate 622 is arranged horizontally. The horizontal arrangement of the second support plate 622 provides a flat and stable support surface for the pump assembly 300, allowing the assembly to be firmly installed on it. During the operation of the cleaning equipment, the pump assembly 300 will be subjected to external forces such as vibration. However, due to the stable support of the first support plate 612, the pump assembly 300 can maintain a fixed position, avoiding the impact of shaking or displacement on the filtration effect, thereby ensuring the normal operation of the cleaning equipment.

[0062] Specifically, the second connecting plate 621 can be set in the vertical direction.

[0063] Specifically, the cleaning equipment also includes a second fixing member 820. The second fixing member 820 is disposed around the outer periphery of the filter 200, and both ends of the second fixing member 820 are fixedly connected to the second support plate 622. The pump assembly 300 can be stably fixed to the second support plate 622 by means of the second fixing member 820.

[0064] More specifically, two second fasteners 820 may be provided. The two second fasteners 820 may be provided at both ends of the pump assembly 300, thereby enhancing the fixation between the pump assembly 300 and the second support plate 622.

[0065] In some embodiments, the housing 500 includes a base plate 510 and a side plate 520. The base plate 510 is connected to the side plate 520. The end of the first stepped structure 610 away from the second stepped structure 620 is connected to the base plate 510. The side plate 520, the base plate 510, and the first stepped structure 610 form a first receiving chamber for housing the liquid storage tank 100. Based on the overall layout requirements of the cleaning equipment, the space formed by the side plate 520, the base plate 510, and the first stepped structure 610 is rationally utilized to construct a first receiving chamber specifically for housing the liquid storage tank 100. This arrangement allows for efficient use of the internal space of the cleaning equipment, avoids space waste caused by haphazard placement of components, and makes the cleaning equipment structure more compact and orderly.

[0066] Specifically, one end of the first L-shaped plate is connected to the base plate 510. More specifically, one end of the first connecting plate 611 is connected to the base plate 510.

[0067] Specifically, one end of the second L-shaped plate is connected to the side plate 520. More specifically, one end of the second support plate 622 is connected to the side plate 520.

[0068] In some embodiments, the cleaning device further includes a filter tube, one end of which is connected to a filter 200 and the other end of which is connected to a liquid storage tank 100; the end of the second step structure 820 away from the first step structure 810 is connected to a side plate 520, and the second step structure 820, the upper surface of the liquid storage tank 100 and the side plate 520 form a second receiving chamber for receiving the filter tube.

[0069] In some embodiments, the cleaning equipment further includes a three-way valve and a pressure gauge, the three-way valve being connected to the pump assembly 300, the pressure gauge, and the nozzle 400, respectively.

[0070] It should be noted that the three-way valve can flexibly distribute the flow of cleaning fluid according to different cleaning operation needs. For example, when checking the pressure during the start-up of the cleaning equipment, the cleaning fluid can be directed to the pressure gauge to monitor whether the pressure of the cleaning equipment is normal. During normal cleaning operations, all or part of the cleaning fluid can be directed to nozzle 400 to achieve effective cleaning of nozzle 400.

[0071] The pressure gauge, in conjunction with the three-way valve, allows for real-time monitoring of the cleaning fluid pressure. Appropriate pressure is crucial for cleaning effectiveness. Excessive pressure may damage the nozzle 400, while insufficient pressure will prevent proper cleaning. The real-time display on the pressure gauge allows operators to adjust the pump assembly 300's operating status or distribute the flow rate via the three-way valve to ensure the cleaning fluid pressure remains stable within the appropriate range, thereby improving cleaning quality and equipment safety.

[0072] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
