Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment, specifically relating to a vacuum cleaning device suitable for products with complex structures. Background Technology

[0002] Currently, the industry primarily uses ultrasonic and pneumatic oscillation equipment, along with cleaning agents, to clean products with complex structures such as large gaps, shallow channels, and holes. Through ultrasonic vibration and pneumatic oscillation, air inside the product escapes, allowing the cleaning agent to penetrate and clean the gaps, channels, and deep holes within the product.

[0003] However, in actual cleaning processes, when cleaning products with complex structures such as deep blind holes and long closed channels, air residue can still remain in the gaps and deep holes of the product after ultrasonic vibration and air vibration. This prevents the cleaning agent from penetrating, resulting in ineffective removal of oil stains inside the product and poor cleaning performance. At the same time, excessively strong ultrasonic waves can damage the surface of aluminum-based and copper-based products, causing white spots and increasing the product defect rate. For products with relatively thin structures, ultrasonic waves and air vibration can increase product deformation and defects. In addition, during air vibration cleaning, there is a higher risk of the product falling into the tank, increasing the design difficulty and cost of product hangers. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved vacuum cleaning equipment suitable for products with complex structures.

[0005] To solve the above technical problems, the present invention adopts the following technical solution:

[0006] A vacuum cleaning device suitable for products with complex structures includes a cleaning tank, a cleaning fluid tank, and a circulation pipeline. The cleaning tank includes a tank body forming a cleaning chamber and a vacuum component for driving the cleaning chamber to a normal pressure or vacuum state, wherein the product to be cleaned is placed in the cleaning chamber. The cleaning fluid tank has a storage chamber for holding the cleaning fluid. The circulation pipeline connects the cleaning chamber and the storage chamber. When the cleaning chamber is under normal pressure, the circulation pipeline can drive the cleaning fluid to flow between the cleaning chamber and the storage chamber. When the cleaning chamber is under vacuum, the cleaning fluid enters the crevice or deep hole of the product, or the cleaning fluid flows out from the crevice or deep hole of the product.

[0007] Preferably, the connections between the vacuum component and the circulation pipeline and the cleaning chamber are located near the top and bottom of the cleaning chamber, respectively. This reduces the probability of cleaning fluid entering the vacuum component's vacuum pipeline, thereby reducing the damage rate of the vacuum component and extending its service life.

[0008] Preferably, the tank includes a tank body with an open opening from the top and a sealing cover plate installed at the open opening, forming a cleaning chamber between the tank body and the sealing cover plate. This design is simple and facilitates the placement and removal of products.

[0009] Preferably, the cleaning tank further includes a positioning seat disposed within the cleaning chamber, on which the product to be cleaned is positioned.

[0010] Specifically, the positioning seat is located near the bottom of the cleaning chamber, and a horizontally positioned positioning plane is formed on the positioning seat. The product to be cleaned is placed on the positioning plane. Here, the product is placed horizontally directly on the positioning plane, making it convenient to pick up and put down.

[0011] Preferably, the cleaning tank also includes a monitoring component for monitoring the level of the cleaning fluid in the cleaning chamber. This facilitates precise control of the cleaning fluid level in the cleaning chamber.

[0012] Preferably, the circulation pipeline includes an inlet pipe connecting the cleaning chamber and the storage chamber, and a return pipe connecting the cleaning chamber and the storage chamber, wherein the inlet pipe and the return pipe are respectively located near the bottom and top of the storage chamber. Here, the oil contaminants contained in the refluxed cleaning fluid are positioned as high as possible in the upper layer of the cleaning fluid in the storage chamber, thereby maintaining the cleanliness of the lower layer of cleaning fluid and ensuring effective cleaning of the product within a certain working range.

[0013] Furthermore, the circulation pipeline also includes a circulation pump, with inlet and return pipes connected to the circulation pump respectively. Here, based on the same circulation pump, it is ensured that inlet and return are implemented independently, avoiding accidental simultaneous operation of the two.

[0014] Preferably, the vacuum cleaning equipment also includes a replenishment pipeline connected to the liquid storage chamber.

[0015] In addition, the vacuum cleaning equipment also includes an ultrasonic generator installed inside the cleaning chamber for cleaning the product. By combining vacuum cleaning and ultrasonic cleaning, the cleaning effect is effectively improved.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0017] Existing technologies, when cleaning products with complex structures such as deep blind holes and long closed channels, still leave air residue in the gaps and deep holes after ultrasonic vibration and air oscillation. This prevents cleaning agents from penetrating, resulting in ineffective removal of oil stains from the product's interior and poor cleaning performance. Furthermore, excessively strong ultrasonic waves can damage the surface of aluminum-based and copper-based products, causing white spots and increasing the defect rate. For products with relatively thin structures, ultrasonic waves and air oscillation can increase product deformation and defects. In addition, air oscillation cleaning carries a higher risk of products falling into the cleaning tank, increasing the design difficulty and cost of product hangers. This application provides an overall structural design for a vacuum cleaning device suitable for products with complex structures, cleverly addressing the shortcomings and defects of existing technologies. With this vacuum cleaning device, the vacuum component drives the cleaning chamber to a normal pressure state. The product to be cleaned is placed inside the cleaning chamber, and the cleaning liquid in the storage chamber is forced into the cleaning chamber through a circulation pipeline. Then, the vacuum component drives the cleaning chamber to a vacuum state, causing air to escape from the product's crevices or deep holes, allowing the cleaning liquid to enter these crevices or deep holes. Next, the vacuum component drives the cleaning chamber back to a normal pressure state, causing the cleaning liquid in the cleaning chamber to flow back to the storage chamber through the circulation pipeline. The vacuum component then drives the cleaning chamber to a vacuum state again, causing the cleaning liquid inside the product's crevices or deep holes to escape. Finally, the vacuum component drives the cleaning chamber back to a normal pressure state, and the cleaned product is removed. Therefore, compared with the prior art, this utility model, on the one hand, creates a vacuum cleaning environment, enabling effective chemical exchange in the product's crevices or deep holes, thus improving the cleaning effect and reducing the residue of cleaning solution after cleaning, thereby reducing the cost of cleaning solution and the pressure of subsequent cleaning and drying; on the other hand, it has wide applicability and effectively avoids defects caused by ultrasonic waves in products made of special materials; in addition, the product remains stationary during cleaning, effectively reducing the risk of falling into the tank and reducing the design difficulty and cost of the hanging fixture.

[0030] like Figure 1 As shown, the vacuum cleaning equipment applicable to complex structure products involved in this embodiment includes a cleaning tank 1, a cleaning liquid tank 2, and a circulation pipeline 3.

[0031] Specifically, the cleaning tank 1 includes a tank body 10 forming a cleaning chamber q 1 and a vacuum component 11 for driving the cleaning chamber q 1 to a normal pressure or vacuum state, wherein the product to be cleaned is placed in the cleaning chamber q 1.

[0032] The tank 10 includes a tank body 100 with an open opening from the top and a sealing cover 101 installed at the open opening, forming a cleaning chamber q1 between the tank body 100 and the sealing cover 101. This design is simple and facilitates the placement and removal of products.

[0033] For ease of implementation, the vacuum component 11 includes a vacuum pump 110 and a vacuum pipe 111 connecting the vacuum pump 110 and the cleaning chamber q1. The connection between the vacuum pipe 111 and the cleaning chamber q1 is located near the top of the cleaning chamber q1. The vacuum pump 110 is a conventional technology, and the vacuuming parameters (vacuum pressure, vacuuming time, vacuum breaking pressure, vacuum breaking time, and number of cycles) are set by the PLC according to product requirements.

[0034] Meanwhile, the cleaning tank 1 in this embodiment also includes a positioning seat 12 and a monitoring component 13, wherein the positioning seat 12 is disposed in the cleaning chamber q 1, and the product to be cleaned is positioned on the positioning seat 12.

[0035] In some specific embodiments, the positioning seat 12 is located near the bottom of the cleaning chamber q1, and a horizontally positioned positioning plane is formed on the positioning seat 12, on which the product to be cleaned is placed. Here, the product is placed directly horizontally on the positioning plane, making it convenient to pick up and put down.

[0036] The monitoring component 13 uses any conventional level gauge to monitor the level of the cleaning fluid in the cleaning chamber q1. This facilitates precise control of the cleaning fluid level in the cleaning chamber.

[0037] In this example, the cleaning fluid tank 2 has a storage chamber q2 for holding the cleaning fluid. The circulation pipeline 3 connects the cleaning chamber q1 and the storage chamber q2. When the cleaning chamber q1 is under normal pressure, the circulation pipeline 3 can drive the cleaning fluid to flow between the cleaning chamber q1 and the storage chamber q2. When the cleaning chamber q1 is under vacuum, the cleaning fluid enters the gap channel or deep hole on the product, or the cleaning fluid flows out from the gap channel or deep hole on the product.

[0038] In some specific embodiments, the connection point between the circulation pipeline 3 and the cleaning chamber q1 is located near the bottom of the cleaning chamber. This reduces the probability of cleaning fluid entering the vacuum component's vacuum pumping pipeline, thereby reducing the damage rate of the vacuum component and extending its service life.

[0039] The circulation pipeline 3 includes an inlet pipe 30 connecting the cleaning chamber q1 and the storage chamber q2, and a return pipe 31 connecting the cleaning chamber q1 and the storage chamber q2. The inlet pipe 30 and the return pipe 31 are respectively positioned near the bottom and top of the storage chamber q2. This design ensures that any oil contaminants contained in the returned cleaning fluid remain as high as possible in the upper layer of the cleaning fluid in the storage chamber, thus maintaining the cleanliness of the lower layer and ensuring effective cleaning of the product within a specific working range.

[0040] Furthermore, the circulation pipeline 3 also includes a circulation pump 32, with an inlet pipe 30 and a return pipe 31 connected to the circulation pump 32. Here, based on the same circulation pump, it is ensured that inlet or return is carried out independently, avoiding accidental simultaneous operation of the two.

[0041] In other words, the inlet pipe 30 of this embodiment includes a first pipe 301 and a second pipe 302 connected to the two ports of the circulation pump 32, and a first valve 303 and a second valve 304 correspondingly disposed on the first pipe 301 and the second pipe 302; the return pipe 31 includes a third pipe 311 and a fourth pipe 312 connected to the second pipe 302 and the first pipe 301 respectively, and a third valve 313 and a fourth valve 314 correspondingly disposed on the third pipe 311 and the fourth pipe 312, wherein the first pipe 301 and the third pipe 311 are connected side by side to the bottom of the cleaning tank 1, the second pipe 302 is connected to the bottom of the cleaning liquid tank 2, and the connection point between the fourth pipe 312 and the cleaning liquid tank 2 is located above the surface of the cleaning liquid.

[0042] Furthermore, the vacuum cleaning equipment in this embodiment also includes an ultrasonic generator (not shown in the figure, but easily understood) disposed in the cleaning chamber q1 for cleaning the product, and a replenishment pipeline 4 connected to the liquid storage chamber q2 for replenishing the liquid storage chamber q2 with cleaning fluid. By combining vacuum cleaning and ultrasonic cleaning, the cleaning effect is effectively improved.

[0043] In summary, after adopting this vacuum cleaning equipment, the vacuum component drives the cleaning chamber to a normal pressure state. The product to be cleaned is placed in the cleaning chamber, and the cleaning liquid in the storage chamber is driven into the cleaning chamber through the circulation pipeline. Then, the vacuum component drives the cleaning chamber to a vacuum state, causing the air inside the crevice channels or deep holes of the product to escape, and then the cleaning liquid enters the crevice channels or deep holes of the product. Next, the vacuum component drives the cleaning chamber to return to a normal pressure state, and the cleaning liquid in the cleaning chamber flows back to the storage chamber through the circulation pipeline. Then, the vacuum component drives the cleaning chamber to a vacuum state again, causing the cleaning liquid inside the crevice channels or deep holes of the product to escape. Finally, the vacuum component drives the cleaning chamber to return to a normal pressure state, and the cleaned product is taken out. Therefore, compared with the prior art, this utility model has the following advantages: First, by creating a vacuum cleaning environment, it enables effective chemical exchange within the product's crevices or deep holes, effectively improving the cleaning effect while reducing cleaning fluid residue after cleaning, thus lowering the cost of cleaning fluid and the pressure of subsequent cleaning and drying. Second, it has wide applicability, effectively avoiding defects caused by ultrasonic cleaning in products made of special materials. Furthermore, the product remains stationary during cleaning, effectively reducing the risk of it falling into the cleaning tank and reducing the design difficulty and cost of the hanging fixtures. Third, it reduces the probability of cleaning fluid entering the vacuum component's vacuum piping, thereby reducing the damage rate of the vacuum component and extending its service life. Fourth, the oil contaminants contained in the refluxed cleaning fluid are kept as high as possible in the upper layer of the cleaning fluid in the storage chamber, thus maintaining the cleanliness of the lower layer of cleaning fluid and ensuring the cleaning effect on the product within a certain working range. Simultaneously, based on the same circulating pump, it ensures that liquid inlet or reflux is carried out separately, avoiding accidental simultaneous operation of the two. Fifth, by combining vacuum cleaning and ultrasonic cleaning, it effectively improves the cleaning effect.

[0044] The present invention has been described in detail above, but it is not limited to the embodiments described above. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the protection scope of the present invention.
