[0026] ​​​​​​The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] like Figures 1 to 9 The steam suction device shown includes a housing 1. The housing 1 is provided with a suction device 3 located on the upper side of the operating station 2, a filter mechanism communicating with the operating station 2 and the suction device 3 respectively, and the filter mechanism is provided with a first filter housing 4 communicating with the operating station 2, a first filter cavity 40 located in the first filter housing 4, a first baffle part 41 located in the first filter cavity 40 and in contact with steam, and a first collection assembly 42 for collecting liquid. The first baffle part 41 is used to drive the steam to condense into liquid and transfer it to the first collection assembly 42.

[0030] By setting a first baffle, this utility model can extend the travel distance of paint remover vapor in the first filter chamber and cause the paint remover vapor to condense into droplets, thereby transferring the paint remover liquid to the first collection component. This avoids the waste caused by a large amount of vapor being directly drawn away, reduces the consumption of paint remover, reduces the number of times the operator needs to add paint remover, and further improves paint removal efficiency and saves manpower.

[0031] Specifically, the suction device located on the upper side of the operating station and the filtering mechanism communicated with the operating station and the operating station are equipped in the shell, forming a relatively complete steam treatment system. The suction device can suck the paint remover steam generated by the operating station, and the first filtering shell provides a relatively closed space environment. When the paint remover steam contacts the first barrier part, the first barrier part increases the moving distance of the steam, a part of the steam adheres to the surface of the first barrier part, and then the heat of the steam is lost, so that condensation occurs, and the steam changes from gaseous state to liquid state. The first collecting assembly receives the liquid condensed by the first barrier part, realizes the recycling of the paint remover steam which would be directly sucked away and wasted, avoids the loss of the paint remover in the bath, and reduces the demand for subsequent replenishment of the paint remover.

[0032] Further, as a preferred embodiment of the utility model but not limited, the utility model improves the workshop working environment, reduces the corrosion of the paint remover steam to the equipment in the workshop and the potential harm to human health, and solves the problem of waste of paint remover caused by direct suction of the steam by the existing steam suction device by setting the first barrier part to promote condensation and collection of the paint remover steam, so that the paint remover can be recycled, the production cost is reduced, and the use efficiency of the paint remover is improved. The steam suction device effectively solves the problem of frequent replenishment of the paint remover, so that the paint stripping work can be more coherent and smooth, the time delay caused by replenishment of the paint remover is reduced, the paint stripping work amount per unit time is improved, and the overall efficiency of paint stripping is improved.

[0033] As shown in the steam suction device, Figure 6 The first barrier part 41 is provided with a first barrier part body 411 connected in the first filtering cavity 40, a first flap 412 connected on one side of the first barrier part body 411, and a second flap 413 connected on the other side of the first barrier part body 411. The first flap 412 and the second flap 413 are inclined, the first barrier part body 411 is provided with an opening 4111, and the first barrier part body 411 extends in the transverse direction.

[0034] The side wall of the first filtering shell 4 is provided with a first connecting part 43, and the end of the first barrier part body 411 is provided with a first matching part 4112. The first connecting part 43 is connected with the first matching part 4112, so that the extension direction of the first barrier part 41 intersects with the moving direction of the steam.

[0035] Further, as the preferred embodiment of the utility model but not limited, the first and second flaps are arranged obliquely, which increases the contact area and contact time of the paint remover vapor with the first barrier part. When the vapor enters the first filter cavity, it will fully contact with the oblique first and second flaps. The vapor is more likely to exchange heat in the process of flowing on the surface of the first and second flaps, which promotes the condensation of the vapor and helps to improve the condensation efficiency of the paint remover vapor, so as to more effectively convert the vapor into liquid and realize the recovery of the paint remover, reducing waste.

[0036] Specifically, the first barrier part body is provided with an opening, so that when the vapor passes through the first barrier part body, part of the vapor can pass through the opening, forming a complex airflow channel. This not only allows the vapor to continuously contact the first barrier part body and the first and second flaps during the process of passing through the first barrier part body, but also causes the flow rate and flow direction of different parts of the vapor to change when passing through the opening, further increasing the contact opportunity of the vapor with the first barrier part, strengthening the condensation process and improving the recovery efficiency of the paint remover vapor.

[0037] In addition, part of the vapor located on the first barrier part body can move downward through the opening, avoiding the accumulation of liquid on the first barrier part body. The opening can guide the liquid droplets to flow back to the first collection assembly under the action of gravity, reducing the step of transferring the cooled paint remover by manpower.

[0038] Preferably, the first flap 412 and the second flap 413 are arranged in a spread shape.

[0039] Further, the first flap 412 and the second flap 413 are arranged symmetrically.

[0040] Specifically, the side wall of the first filter shell is provided with a first connecting part, and the end of the first barrier part body is provided with a first matching part, and the two are connected so that the extension direction of the first barrier part intersects with the moving direction of the vapor. This connection method can make the first barrier part more stably installed in the first filter cavity, ensuring that the first barrier part will not easily displace or shake under the impact of the vapor, which is conducive to the device to continuously and stably play its function of condensing and collecting paint remover, avoiding performance degradation or failure caused by loose or displaced parts.

[0041] Optionally, in some embodiments, the first connecting part is a groove, and the first matching part is a protrusion.

[0042] Optionally, in some embodiments, the first connecting part is a protrusion, and the first matching part is a groove.

[0043] Optionally, in some embodiments, the first connecting part is a magnetic attraction piece, and the first matching part is a magnetic attraction piece.

[0044] Specifically, the extension direction of the first barrier portion intersects with the moving direction of the steam, which changes the original flow path of the steam, so that the steam can be in contact with the first barrier portion more fully, thereby improving the steam condensation treatment effect and further improving the collection and recovery effect of the paint stripper steam, while avoiding the steam being directly sucked away without sufficient treatment, reducing the waste of paint stripper and improving the overall work efficiency of the steam suction device.

[0045] Preferably, the first barrier portion is arranged in a horizontal direction. Optionally, in some embodiments, when the steam of the paint stripper enters the first filtering cavity, the steam is guided to various positions of the first filtering cavity and is in contact with and condensed on the surface of the first barrier portion due to the vertical extension direction of the first barrier portion body relative to the steam inlet direction of the paint stripper. This design can increase the residence time of the steam in the first barrier portion body, thereby improving the condensation efficiency.

[0046] Further, the first fitting portion is arranged along the extension direction of the first barrier portion body, the first flap extends away from the second flap, the second flap extends away from the first flap, and the extension directions of the first flap and the second flap are arranged in an eight-shaped manner. Optionally, in some embodiments, when the first flap is located on the upper side of the first barrier portion body, the liquid drops formed in the first flap from the steam move from the first flap to the first barrier portion body and are collected, or move to the opening, and the liquid drops drop from the opening downward, and when the first flap is located on the lower side of the first barrier portion body, the steam drops from the first flap obliquely downward.

[0047] Further, the plurality of first upper barrier portions are arranged on the same horizontal line, and the plurality of first lower barrier portions are arranged on the same horizontal line. In some embodiments, in the vertical direction, the first upper barrier portions and the first lower barrier portions are arranged alternately, the first upper barrier portions are arranged between two groups of first lower barrier portions in the vertical direction, and the first lower barrier portions are arranged between two groups of first upper barrier portions in the vertical direction.

[0048] In the horizontal direction, in some embodiments, the first upper barrier portions and the first lower barrier portions are arranged alternately, and a spacing space is arranged between two first lower barrier portions. The first upper barrier portions located on the lower side of the first lower barrier portions or on the upper side of the first lower barrier portions are arranged on the upper side or the lower side of the spacing space between the two first lower barrier portions.

[0049] The steam needs to pass through the space between two adjacent first upper barrier portions and then be transferred to the space between two adjacent first lower barrier portions, further prolonging the moving distance of the steam.

[0050] Optionally, in the embodiment, the length of the first barrier body is close to the length direction of the first filter shell, the width of the first barrier body is smaller than the width of the first filter shell, the first flap of the first upper barrier is close to the first flap of the first lower barrier, the first flap of the first upper barrier is arranged in parallel with the first flap of the first lower barrier, the second flap of the first upper barrier is away from the second flap of the first lower barrier, and the second flap of the first upper barrier is arranged in parallel with the second flap of the first lower barrier, so that a narrow channel is formed between the adjacent first upper barrier and the first lower barrier, the steam passing through the narrow channel is reduced in speed, and the moving time of the steam in the first filter cavity is further prolonged.

[0051] As shown in the steam suction device, Figure 7 The first collection assembly 42 comprises a backflow groove 421 arranged on the lower side of the first barrier 41 and communicated with the operation station 2, and first filter openings 422 respectively communicated with the backflow groove 421 and the first filter cavity 40.

[0052] Further, as a preferred embodiment of the utility model but not limited, the backflow groove is arranged on the lower side of the first barrier and communicated with the operation station, which can effectively collect the paint remover liquid condensed by the first barrier. After the paint remover vapor is condensed into liquid under the action of the first barrier, the liquid flows into the backflow groove under the action of gravity, avoiding the situation that the condensed paint remover liquid flows everywhere and cannot be collected, and ensuring the effective recovery of the paint remover.

[0053] Specifically, the backflow groove collects the paint remover that may be lost, and then the paint remover is backflowed to the liquid tank on the operation station through the channel of the backflow groove, realizing the recycling of the paint remover, reducing the waste of the paint remover, improving the utilization rate of the paint remover, and reducing the production cost.

[0054] Specifically, the first filter openings are respectively communicated with the backflow groove and the first filter cavity. On the one hand, part of the paint remover vapor flows to the first filter cavity through the backflow groove, which increases the path of steam transfer and accelerates the speed of steam flow. On the other hand, the paint remover vapor can smoothly flow into the backflow groove after being condensed in the first filter cavity, forming an orderly liquid flow path, and ensuring that the condensed liquid can smoothly enter the backflow groove for collection.

[0055] In addition, the backflow groove arranged in an inclined manner can block the steam and reduce the rising speed of the steam, so that part of the energy of the rising steam is dissipated and converted into liquid droplets before the steam enters the first filter cavity, and on the other hand, the paint remover forming liquid droplets can be moved from the backflow groove to the operation station.

[0056] As shown in the steam suction device, Figure 2The shown steam suction device, the filtering mechanism further comprises a purification assembly 5 in communication with the first filtering shell 4 and the suction device 3 respectively.

[0057] Further, as a preferred embodiment of the present application but not limited, the purification assembly can further purify the paint remover steam or the condensed liquid after the first filtering shell is not completely treated. Specifically, during the paint removal process, some impurities, small particles or other pollutants may be mixed in the paint remover steam, and even after the preliminary treatment of the first barrier part and the first collection assembly, part of the impurities may still remain. The purification assembly can filter, adsorb or other purification operation to these impurities, to ensure that the fluid entering the suction device is more pure, to improve the quality of the recovered paint remover and the purity of the exhaust gas. This not only helps to improve the working environment of the workshop, reduce the health hazards to the operators, but also meets the environmental protection requirements, reduces the environmental risks caused by pollutant emissions, and makes the operation of the paint removal machine more environmentally friendly.

[0058] Specifically, if impurities such as powder after paint removal and metal enter the suction device, they will accumulate inside the suction device, affecting the performance of the suction device, such as causing blockage, wear or corrosion, etc. Long-term will reduce the working efficiency of the suction device, and even cause the suction device to be damaged, which requires more frequent maintenance or replacement. By purifying the steam through the purification assembly, the impurities entering the suction device can be reduced, the working burden of the suction device can be reduced, and the risk of damage can be reduced, thereby prolonging the service life of the suction device, reducing the maintenance cost and equipment downtime of the equipment, and improving the working stability and reliability of the entire paint removal machine.

[0059] Optionally, in some embodiments, the purification assembly can filter the gas through a filtering device, such as using a filter screen of different sizes, a fiber structure filter; it can also be neutralized by passing into a chemical solution, such as using sodium hydroxide alkaline absorbent to neutralize the acidic components in the paint remover steam, or using an absorbent with a specific functional group to react with certain active ingredients in the paint remover, thereby changing its chemical properties, making it easier to be treated or discharged later; it can also be through multiple condensation treatment of the paint remover steam, which can gradually separate components with different boiling points, realize the fractional purification and recovery of different substances in the steam, and improve the recovery purity and effect of the paint remover.

[0060] As Figure 6The steam suction device shown, the first barrier part 41 includes a first upper barrier part 414 and a first lower barrier part 415 arranged in a vertical direction, the first upper barrier part 414 is provided with a plurality of and interval arrangement, the first lower barrier part 415 is provided with a plurality of and interval arrangement, the first upper barrier part 414 The first flap 412 and the second flap 413 are inclined to the first lower barrier part 414 direction, the first upper barrier part 414 and the first lower barrier part 415 staggered arrangement.

[0061] Further, as a preferred embodiment of the utility model but not limited, the first upper barrier part and the first lower barrier part are arranged in a vertical direction and staggered, forming a multi-level structure. When the paint remover vapor enters the first filter cavity, it will flow between different levels of the first upper barrier part and the first lower barrier part. Due to the staggered arrangement between them, the steam needs to shuttle in this complex structure, prolonging the residence time of the steam in the first filter cavity.

[0062] Specifically, the steam is in full contact with the first upper barrier part and the first lower barrier part and its flaps arranged at intervals, increasing the contact area and contact opportunity of the steam with the barrier part, providing more time and space conditions for the condensation of the steam, so that the steam can be more fully exchanged with the barrier part, thereby significantly improving the condensation efficiency, and further converting more paint remover vapor into liquid, which is beneficial to the recovery and reuse of the paint remover and reduces the waste of the paint remover.

[0063] Specifically, the first flap and the second flap of the first upper barrier part are inclined to the first lower barrier part, guiding the steam to flow orderly between different levels of the barrier part. This inclined design changes the natural flow path of the steam, making it form a circuitous flow trajectory when passing through the first barrier part, further enhancing the interaction between the steam and the barrier part.

[0064] Of course, in some embodiments, the first flap and the second flap of the first lower barrier part are inclined to the first upper barrier part.

[0065] Specifically, the first upper barrier part and the first lower barrier part are arranged in a central symmetric manner, and the cavity formed by the first upper barrier part and the cavity formed by the first lower barrier part are oppositely arranged.

[0066] As Figure 2The steam suction device is shown, the filtering mechanism is provided with a second filtering assembly 6 located between the operation station 2 and the suction device 3, a second filtering cavity 60 located in the second filtering assembly 6, a second barrier part 61 located in the second filtering cavity 60 and in contact with steam, and a second collecting assembly 62 in communication with the second barrier part 61, the second barrier part 61 is used to drive steam to condense into liquid and transfer to the second collecting assembly 62, the second filtering assembly 6 is arranged adjacent to the first filtering shell 4, and the outlet of the first filtering cavity 40 and the outlet of the second filtering cavity 60 are both in communication with the suction device 3.

[0067] Further, as a preferred embodiment of the utility model but not limited, by arranging the second filtering assembly adjacent to the first filtering assembly, part of the paint remover steam is transferred from the outlet of the first filtering cavity to the suction device, and part of the steam is transferred from the outlet of the second filtering cavity to the suction device, forming a filtering structure in multiple positions.

[0068] Specifically, the second barrier part can drive steam to condense into liquid and be collected through the second collecting assembly, the second filtering assembly improves the overall condensation and collection efficiency, further reduces the possibility of paint remover steam being directly sucked away by the suction device, thereby more effectively recycling the paint remover and reducing the waste of the paint remover.

[0069] Specifically, since the second filtering assembly cooperates with the first filtering assembly, even if part of the paint remover steam is not sucked in the first filtering shell during the paint removal process, or the paint remover steam is scattered during the jig transfer process, the second filtering assembly can continue to play a certain suction, condensation and collection role, ensuring that the transfer of steam is not affected by the scattering position and the station transfer position, reducing the risk of large loss of paint remover due to the limited suction range of a single filtering assembly, and ensuring that the paint removal machine can work continuously and stably.

[0070] In addition, the second filtering cavity, the second barrier part and the second collecting assembly in the second filtering assembly can more accurately process the steam. When the paint remover steam contacts the second barrier part, the second barrier part increases the moving distance of the steam, part of the steam adheres to the surface of the second barrier part, and then the heat of the steam is lost, so that condensation occurs, and the steam changes from gas to liquid. The second collecting assembly receives the liquid condensed by the second barrier part, realizes the recycling of the paint remover steam that would be directly wasted, avoids the loss of the paint remover in the form of gas, and further reduces the loss of the paint remover in the tank and the demand for subsequent replenishment of the paint remover.

[0071] As Figure 4The steam suction device shown, the second barrier part 61 is equipped with the second barrier part body 611 connected in the second filter cavity 60, the third flaps 612 connected on one side of the second barrier part body 611, the fourth flaps 613 connected on the other side of the second barrier part body 611, the third flaps 612 and the fourth flaps 613 are obliquely arranged, and the second barrier part body 611 extends vertically.

[0072] Further, as a preferred embodiment of the present application, the third flaps and the fourth flaps are obliquely arranged, which increases the contact area of the paint remover steam with the second barrier part. When the steam enters the second filter cavity, it will come into contact with these inclined third flaps and fourth flaps. When the steam flows on the surface of the third flaps and the fourth flaps, its flow path will be lengthened, and the contact with the surface of the third flaps and the fourth flaps will be more sufficient. This helps to increase the heat exchange opportunities of the steam with the second barrier part, making the steam more likely to condense, thereby converting more steam into liquid and improving the condensation efficiency of the paint remover steam.

[0073] Specifically, due to the oblique arrangement of the third flaps and the fourth flaps, they will guide the steam to flow along a specific path in the second filter cavity. This guidance can make the steam flow in an orderly manner in the second barrier part, avoiding the situation that some steam may pass through without being fully treated due to disordered flow. By guiding the steam flow, it is ensured that the steam stays on the surface of the second barrier part for a long enough time to fully utilize the condensation function of the second barrier part, thereby improving the recovery effect of the paint remover.

[0074] In addition, the vertical extension structure of the second barrier part body is beneficial to the layered treatment of the steam. Steam at different heights can come into contact with the third flaps, the fourth flaps and the second barrier part body at different positions, making the condensation treatment of the steam more uniform and efficient, improving the efficiency of the entire second barrier part in condensing and collecting the paint remover, and helping to further reduce the waste of the paint remover.

[0075] Preferably, the third flaps and the fourth flaps are arranged in a figure-eight shape.

[0076] Further, the third flaps and the fourth flaps are symmetrically arranged.

[0077] As Figure 4The steam suction device shown, the second barrier part 61 includes the second front barrier part 614 and the second rear barrier part 615 arranged in the horizontal direction, the second front barrier part 614 is provided with multiple and interval arrangement, the second rear barrier part 615 is provided with multiple and interval arrangement, the third flap 612 and the fourth flap 613 of the second front barrier part 614 are inclined to the second rear barrier part 615 direction, the second front opening 6141 for connecting the operation station 2 is arranged between two adjacent second front barrier parts 614, the second rear opening 6151 for connecting the second front opening 6141 and the second filter cavity 60 is arranged between two adjacent second rear barrier parts 615, and the second front barrier part 614 and the second rear barrier part 615 are staggered arrangement.

[0078] Further, as a preferred embodiment of the utility model but not limited, the second front barrier part and the second rear barrier part are staggered arranged in the horizontal direction, and the third flap and the fourth flap of the second front barrier part are inclined to the second rear barrier part direction, which increases the contact area and contact opportunity of the paint stripper steam and the second barrier part.

[0079] Specifically, the arrangement of the second front opening and the second rear opening prolongs the tortuous path of the steam in the second filter cavity, guides the steam to flow between different positions of the second barrier part, and the tortuous flow path can uniformly distribute the steam in the second filter cavity, avoiding the straight-line flow of the steam.

[0080] Specifically, the second front barrier part and the second rear barrier part are arranged in a central symmetry mode, and the cavity formed by the second front barrier part and the cavity formed by the second rear barrier part are oppositely arranged.

[0081] The third flap of the second front barrier part is close to the third flap of the second rear barrier part, the third flap of the second front barrier part is arranged in parallel with the third flap of the second rear barrier part, the fourth flap of the second front barrier part is away from the fourth flap of the second rear barrier part, and the fourth flap of the second front barrier part is arranged in parallel with the fourth flap of the second rear barrier part, so that a narrow channel is formed between the adjacent second front barrier part and the second rear barrier part, the steam passing through the narrow channel will reduce the speed, and the moving time of the steam in the second filter cavity is further prolonged.

[0082] As Figure 9 shown in the steam suction device, the lower side of the second filter assembly 6 is provided with a second filter assembly opening 63, the second collection assembly 62 comprises a second collection part 621 in communication with the second filter assembly opening 63, and a second collection opening 622 in communication with the second collection part 621, and the second blocking part 61 is arranged from top to bottom and from outside to inside.

[0083] Further, as a preferred embodiment of the utility model but not limited, the second filter assembly opening at the lower side of the second filter assembly is in communication with the second collection part, which facilitates the collection of the condensed paint remover liquid. When the paint remover vapor is condensed into liquid under the action of the second blocking part, the liquid will naturally flow into the second collection part through the second filter assembly opening under the action of gravity, ensuring that the liquid can flow orderly to the second collection part, avoiding the accumulation of liquid in the second filter assembly, improving the efficiency and convenience of liquid collection, so that the recovered paint remover can be better collected and stored for subsequent reuse.

[0084] Specifically, the second blocking part is arranged from top to bottom and from outside to inside, and this inclined manner guides the paint remover vapor to flow gradually inward and downward. When the vapor flows in the second filter cavity, due to the inclination of the second blocking part, the vapor will flow along the surface of the second blocking part, prolonging the contact time and contact area of the vapor with the second blocking part.

[0085] In addition, the vapor will continuously exchange heat with the inclined second blocking part during the flow process, which is more conducive to the condensation of the vapor, so that more vapor can be converted into liquid, improving the condensation efficiency of the paint remover vapor and reducing the waste of paint remover caused by vapor escape.

[0086] As Figures 1 to 9 shown in the paint stripping machine, comprising the steam suction device as described above.

[0087] In the conventional paint stripping machine, the paint remover vapor diffused in the workshop will pollute the environment and harm the health of equipment and personnel. In the present utility model, the steam suction device in the paint stripping machine can condense and collect the paint remover vapor, avoiding a large amount of vapor diffused in the workshop, improving the air quality of the workshop, reducing the corrosion risk of the equipment in the workshop, providing a safer and healthier working environment for the operators, and also reducing the potential pollution of the paint remover to the environment, meeting the environmental protection requirements.

[0088] Specifically, thanks to the aforementioned steam extraction device, the paint stripper effectively solves the problem of waste caused by the direct extraction of paint stripper vapor in existing paint strippers. Specifically, in some embodiments, the arrangement of the first filter housing and the second filter assembly in the steam extraction device enables the paint stripper vapor to condense and be recovered into liquid, which is then returned to the operating station, achieving the recycling of the paint stripper. This significantly reduces the frequency and amount of paint stripper replenishment, conserves paint stripper resources, and lowers the cost of paint stripping operations.

[0089] Furthermore, during the paint stripping process, if the paint stripper decreases frequently due to vapor escape, operation needs to be interrupted to replenish the paint stripper, affecting work efficiency. This new paint stripper effectively recovers the paint stripper, avoiding frequent replenishment, allowing the paint stripping process to proceed more continuously and stably. This improves the machine's efficiency, reduces downtime caused by paint stripper replenishment, and enables the machine to process more workpieces per unit time, thus enhancing its overall performance.

The first baffle part 41 is used to drive the steam to condense into liquid and transfer it to the first collection assembly 42.

[0092] By setting the first baffle 41, this utility model can extend the travel distance of paint remover vapor within the first filter chamber 40 and cause the paint remover vapor to condense into droplets, thereby transferring the paint remover liquid to the first collection component 42. This avoids the waste caused by a large amount of vapor being directly drawn away, reduces the consumption of paint remover, reduces the number of times the operator needs to add paint remover, further improves paint removal efficiency and saves manpower.
