Description

Technical Field

[0001] This utility model relates to the technical field of air bag cleaning, and in particular to an air bag cleaning device. Background Technology

[0002] Currently, there are no large-scale, industrially available air bag cleaning devices on the market. Existing technologies mostly use a cycle of inflating and deflating air bags with air or nitrogen to achieve cleaning. This traditional method is effective for cleaning general gases, but in practical applications, the composition and source of the gases are often complex. For example, when cleaning highly adhesive gases such as cooking fumes, conventional cleaning methods are often ineffective. Manually cleaning air bags is not only time-consuming and labor-intensive, but also fails to completely remove residues, seriously affecting the accuracy and reliability of test results. In addition, existing air bag cleaning devices typically discharge exhaust gas without filtration, directly releasing VOCs (volatile organic compounds) into the air, easily leading to indoor air pollution. Therefore, developing a cleaning device that can efficiently and thoroughly clean air bags, especially capable of handling complex gas compositions, has become an urgent technical problem to be solved. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art, such as the difficulty in cleaning some components adhering to the inner wall of the air bag and the easy emission of toxic components from the air bag into the air, and to provide an air bag cleaning device.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A gas bag cleaning device is provided, comprising a housing and a heating chamber, the heating chamber being disposed inside the housing. The housing has an air inlet and an air outlet, and the heating chamber has a connection port. The air inlet and the connection port are connected via an air inlet pipe, and the air outlet and the connection port are connected via an air outlet pipe. The air inlet pipe is connected to an external air supply device through the air inlet, and the air outlet pipe is equipped with an air pump and is connected to the outside of the housing through the air outlet. The connection port connects to the gas bag inside the heating chamber. The device is equipped with a first solenoid valve, which is used to switch the connection between the air bag and the air inlet pipe or the air outlet pipe; the air bag cleaning device also includes a heating device, which is disposed around the heating chamber and is used to heat the air bag inside the heating chamber; the air outlet pipe is also equipped with a VOC filter assembly, which includes a VOC detection device and a VOC adsorption device, the VOC detection device is used to detect the VOC concentration of the gas discharged from the air bag, and the VOC adsorption device is used to filter the gas discharged from the air bag.

[0006] In this solution, the inner bag is placed inside the heating chamber. The air bag is evacuated until it deflates via an exhaust pipe and a suction pump. An external air source is then supplied to the air bag through an intake pipe for rinsing and cleaning. A first solenoid valve switches between the intake and exhaust pipes, resulting in a simple structure with good control. The flow rate of the intake or exhaust can also be adjusted via the first solenoid valve to effectively improve the cleaning effect of the air bag. A heating device is installed to activate impurities adhering to the inner wall of the air bag during cleaning, making them easier to detach during gas rinsing and improving the cleaning effect. Simultaneously, this solution also includes a VOC filter component to monitor the VOC concentration of the exhaust gas from the air bag. Users can use this information to determine if the air bag cleaning is adequate. Furthermore, the exhaust gas is filtered by a VOC adsorption device before exiting the heating and cleaning device, preventing toxic components in the exhaust gas from polluting the air.

[0007] Preferably, a baffle is provided inside the heating chamber, the baffle is close to the inner wall of the heating chamber, and a receiving space is formed between the baffle and the inner wall of the heating chamber, and the heating device is disposed in the receiving space.

[0008] In this solution, the heating device is placed in the containing space. The containing space is heated first, and then the air bag is slowly heated by the baffle of the containing space. This avoids the situation where the heating device directly heats the air bag, resulting in uneven heating and inadequate cleaning effect. It also avoids the situation where the air bag comes into contact with the heating device during the inflation process, which could damage the air bag.

[0009] Preferably, the heating device is a heating tube, which is bent and extended multiple times inside the accommodating space to form a tortuous pipeline layout.

[0010] In this solution, heating tubes are used as the heating device. The structure is simple and the cost is low. The tortuous pipes can be laid on the baffle over a large area, so that the heating chamber heats up immediately after starting, the heating speed is faster, and the heating effect is more uniform.

[0011] Preferably, baffles and heating devices are symmetrically arranged on opposite sides inside the heating chamber.

[0012] In this design, the heating chamber is symmetrically arranged to form a receiving space, and multiple heating devices are installed to ensure that both sides of the air bag are heated evenly, avoiding the reduction in cleaning efficiency caused by unilateral heating and the impact of uneven heating on the cleaning effect.

[0013] Preferably, the air bag cleaning device includes a collection pipe inside, the air inlet pipe and the air outlet pipe are arranged in parallel and are both connected to the collection pipe through a first solenoid valve, the collection pipe passes through the connection port and is connected to the air bag in the heating chamber.

[0014] In this solution, a manifold is installed at the connection port, allowing the air bag to be connected to the manifold for air intake or exhaust without having to connect multiple pipes simultaneously. This improves the airtightness of the air bag connection and eliminates the need to manually replace the air bag connecting pipes, making operation more convenient. The manifold connects the intake pipe and the exhaust pipe through the first solenoid valve, allowing direct switching between the intake pipe and the exhaust pipe. The structure is simple.

[0015] Preferably, a second solenoid valve is also provided on the exhaust pipe, and the air pump is connected to the exhaust pipe through the second solenoid valve.

[0016] In this solution, the second solenoid valve is used to control the flow rate of the exhaust pipe. The second solenoid valve is connected to the air pump, and the exhaust rate of the air pump can be controlled through the second solenoid valve. The exhaust flow rate can be controlled according to the actual situation, which effectively improves the cleaning effect of the air bag.

[0017] Preferably, the air bag cleaning device further includes a time relay, which is electrically connected to the first solenoid valve and the second solenoid valve.

[0018] In this solution, the opening and closing times of the first and second solenoid valves are controlled by a time relay. There is no need to manually adjust the solenoid valves. The valves can automatically cycle through preset times, making the operation of the air bag cleaning device more convenient and improving the user experience.

[0019] Preferably, the housing is provided with an outwardly opening door, the heating chamber is a box structure, and the opening direction of the heating chamber is the same as the opening direction of the housing door, and the inner wall of the door can abut against the opening of the heating chamber.

[0020] In this design, the heating chamber has an opening on one side, which makes it convenient for operators to place or retrieve the air bag. By setting an openable and closable door, when the air bag is being cleaned, closing the door of the housing can effectively isolate the internal temperature and noise. When closed, the inner wall of the door abuts against the opening of the heating chamber, which improves the airtightness of the heating chamber during use.

[0021] Preferably, the inner wall of the heating chamber and the inner wall of the door are both lined with heat-insulating material.

[0022] In this solution, heat insulation material is laid inside the heating chamber to prevent heat loss and improve the heating effect of the heating chamber. At the same time, it also prevents the heat from being transferred to the outside of the heating chamber. High temperature can easily damage other components inside the shell and reduce the service life of the components. Heat insulation material is laid on the inner wall of the door to prevent the door and shell from becoming too hot after heating, which could cause injury to the operator.

[0023] Preferably, the inner wall of the heating chamber is also provided with a connecting pipe, which is used to connect the inside and outside of the heating chamber.

[0024] In this design, a connecting pipe is used to regulate the air pressure inside the heating chamber. Connecting the heating chamber to the outside prevents the air bag from becoming too large during air intake, which could cause excessive pressure inside the heating chamber, and also prevents insufficient internal pressure during exhaust, which could lead to incomplete exhaust.

[0025] Preferably, the VOC detection device is disposed within the housing, and the VOC detection device includes a display screen disposed outside the housing.

[0026] In this solution, the VOC detection device can detect the VOC concentration in the gas discharged from the gas bag and display the VOC concentration of each discharge in a timely manner. By comparing the displayed data with the requirements of national or local standards, it can be determined whether the gas bag is cleaned properly, avoiding the situation of inadequate or excessive cleaning of the gas bag, and improving the reliability of the gas bag cleaning device.

[0027] Preferably, the VOC adsorption device includes a box and a VOC adsorption material, the exhaust pipe and the exhaust port are respectively connected to the two sides adjacent to the opening of the box, and the adsorption material is disposed inside the box.

[0028] In this solution, the VOC adsorption device is designed as a box structure, which makes it convenient for users to place or replace the adsorption material. The two sides of the box are connected to ensure that the exhaust gas can be filtered, thus avoiding air pollution caused by unfiltered exhaust.

[0029] The significant advantages of this invention are as follows: In this design, the inner bag is placed inside the heating chamber. The air bag is evacuated until it deflates through an exhaust pipe and a suction pump. An external air source is then introduced into the air bag through an intake pipe for cleaning. A first solenoid valve switches between the intake and exhaust pipes, resulting in a simple structure with good control. The flow rate of the intake or exhaust can also be adjusted via the first solenoid valve, effectively improving the cleaning effect. A heating device activates impurities adhering to the inner wall of the air bag during cleaning, making them easier to detach during gas flushing and further enhancing the cleaning effect. Simultaneously, the air bag cleaning device is equipped with a VOC filter component to detect the VOC concentration in the exhaust gas. Users can use this information to determine if the air bag cleaning is adequate. Furthermore, the exhaust gas is filtered by a VOC adsorption device before exiting the heating and cleaning device, preventing toxic components in the exhaust gas from polluting the air.

[0057] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0058] In this embodiment, as Figure 1-3As shown, a cleaning device for an air bag 700 is provided, including a housing 100 and a heating chamber 200. The heating chamber 200 is disposed inside the housing 100. The housing 100 is provided with an air inlet 110 and an air outlet 120. The heating chamber 200 is provided with a connection port 210. The air inlet 110 and the connection port 210 are connected by an air inlet pipe 400, and the air outlet 120 and the connection port 210 are connected by an air outlet pipe 500. The air inlet pipe 400 is connected to an external air supply device 800 through the air inlet 110, and the air outlet pipe 500 is provided with... An air pump 510 is connected to the outside of the housing 100 through an exhaust port 120. A connection port 210 connects to the air bag 700 inside the heating chamber 200. A first solenoid valve 300 is provided on the air inlet pipe 400 and the exhaust pipe 500. The first solenoid valve 300 is used to switch the connection between the air bag 700 and the air inlet pipe 400 or the exhaust pipe 500. The air bag 700 cleaning device also includes a heating device 230, which is located around the heating chamber 200 and is used to heat the air bag 700 inside the heating chamber 200.

[0059] An inner bag is placed inside the heating chamber 200. Air is drawn from the air bag 700 until it deflates through the exhaust pipe 500 and the suction pump 510. An external air source is then introduced into the air bag 700 through the intake pipe 400 for rinsing and cleaning. A first solenoid valve 300 switches between the intake pipe 400 and the exhaust pipe 500. This design is simple and provides good control. The flow rate of the intake or exhaust can also be adjusted via the first solenoid valve 300 to effectively improve the cleaning effect of the air bag 700. A heating device 230 is installed to activate impurities adhering to the inner wall of the air bag 700 during cleaning, making them easier to detach during gas rinsing and resulting in better cleaning. Simultaneously, this embodiment also includes a VOC filter assembly 600 to detect the VOC concentration in the exhaust gas from the air bag 700. Users can use this information to determine if the air bag 700 has been thoroughly cleaned. Furthermore, the exhaust gas is filtered by the VOC adsorption device before exiting the heating and cleaning device, preventing toxic components in the exhaust gas from polluting the air.

[0060] Specifically, in this embodiment, the external gas delivery device 800 is a nitrogen cylinder. Nitrogen gas is used to flush the inner wall of the gas bag 700. Nitrogen has high stability, is not easily affected by heating, and provides good cleaning results while being safer. In other possible embodiments, the gas delivery device 800 can be an air pump or other gas source. The specific gas can be selected according to the composition inside the gas bag 700, as long as the cleaning requirements are met.

[0061] The heating chamber 200 includes a baffle 220 located inside, close to the inner wall of the chamber. A receiving space is formed between the baffle 220 and the inner wall of the heating chamber 200, and the heating device 230 is disposed within this receiving space. By placing the heating device 230 within the receiving space, the space is heated first, and then the air bag 700 is slowly heated by the baffle 220. This avoids the heating device 230 directly heating the air bag 700, which could lead to uneven heating and inadequate cleaning. It also prevents the air bag 700 from contacting the heating device 230 during inflation, thus avoiding damage. In other embodiments, the baffle 220 can be omitted, and the heating device 230 can be directly installed, as long as contact between the heating device 230 and the air bag 700 is avoided to prevent damage.

[0062] Specifically, such as Figure 2 As shown, the heating device 230 is a heating tube, which is bent and extended multiple times within the accommodating space to form a tortuous pipe layout. Using a heating tube as the heating device 230 results in a simple structure and low cost. The tortuous pipe layout can be laid over a large area on the baffle 220, allowing the heating chamber 200 to heat up immediately after startup, resulting in faster heating speed and more uniform heating effect. In other possible embodiments, the structure of the heating device 230 is not specifically limited. Other heating devices 230 or the layout of the heating device 230 within the heating chamber 200 can be selected according to existing components or heating requirements, as long as the air bag 700 can be heated evenly.

[0063] Furthermore, baffles 220 and heating devices 230 are symmetrically arranged on opposite sides inside the heating chamber 200. The heating chamber 200 symmetrically forms accommodating spaces, and multiple heating devices 230 are installed to ensure that both sides of the air bag 700 are heated evenly, avoiding reduced cleaning efficiency due to unilateral heating and uneven heating affecting the cleaning effect. In this embodiment, baffles 220 are arranged on the upper and lower sides inside the heating chamber 200, forming two accommodating spaces, and two heating tubes are respectively arranged in the upper and lower accommodating spaces. In other possible embodiments, the number and position of baffles 220 and heating devices 230 are not specifically limited; heating devices 230 can be installed on each inner wall of the heating chamber 200, as long as the air bag 700 is heated evenly inside the heating chamber 200.

[0064] In this embodiment, the internal structure of the air bag 700 cleaning device includes a manifold 900, an inlet pipe 400, and an outlet pipe 500 arranged in parallel, both connected to the manifold 900 via a first solenoid valve 300. The manifold 900 passes through a connection port 210 and connects to the air bag 700 within the heating chamber 200. By connecting the manifold 900 to the connection port 210, the air bag 700 only needs to be connected to the manifold 900 for intake or exhaust, eliminating the need to connect multiple pipes simultaneously. This improves the airtightness of the air bag 700 connection and eliminates the need for manual replacement of the air bag 700 connecting pipes 250, making operation more convenient. The manifold 900 connects to the inlet pipe 400 and the outlet pipe 500 via the first solenoid valve 300, allowing direct switching between the two connections, resulting in a simple structure.

[0065] Furthermore, a second solenoid valve 520 is also provided on the exhaust pipe 500, and the suction pump 510 is connected to the exhaust pipe 500 through the second solenoid valve 520. The second solenoid valve 520 is used to control the flow rate of the exhaust pipe 500. By connecting the second solenoid valve 520 to the suction pump 510, the exhaust rate of the suction pump 510 can be controlled through the second solenoid valve 520, and the exhaust flow rate can be controlled according to the actual situation, effectively improving the cleaning effect of the air bag 700. In other possible embodiments, other components can also be provided to control the flow rate of the suction pump 510.

[0066] The air bag 700 cleaning device also includes a time relay, which is electrically connected to the first solenoid valve 300 and the second solenoid valve 520. By controlling the opening and closing times of the first solenoid valve 300 and the second solenoid valve 520 through the time relay, the solenoid valves can be automatically cycled according to a preset time without manual adjustment, making the operation of the air bag 700 cleaning device more convenient and improving the user experience. In other possible embodiments, the opening and closing times of the solenoid valves can also be controlled in other ways, as long as it does not affect the normal use of the solenoid valves.

[0067] In this embodiment, the housing 100 is provided with an outwardly opening door 130, and the heating chamber 200 has a box-like structure 621. The opening direction of the heating chamber 200 is the same as the opening direction of the door 130 of the housing 100, and the inner wall of the door 130 can abut against the opening of the heating chamber 200. The heating chamber 200 has one opening, which facilitates the operator to place or take out the air bag 700. By providing an openable and closable door 130, when the air bag 700 is being cleaned, closing the door 130 of the housing 100 can effectively isolate the internal temperature and noise. When closed, the inner wall of the door 130 abuts against the opening of the heating chamber 200, improving the airtightness of the heating chamber 200 during use.

[0068] Specifically, in this embodiment, such as Figure 3As shown, the door 130 of the housing 100 is located on the front of the air bag 700 cleaning device. Pulling the door 130 outward will open the heating chamber 200. In other embodiments, the door 130 of the housing 100 may also be located on the top of the housing 100. The door 130 can be opened by lifting it upward. The position of the door 130 is not specifically limited and can be set according to actual usage requirements.

[0069] Specifically, the inner walls of the heating chamber 200 and the door 130 are both lined with heat insulation material 240. Lining the heating chamber 200 with heat insulation material 240 prevents heat loss, improves the heating effect of the heating chamber 200, and also prevents heat from being transferred to the outside of the heating chamber 200. High temperatures can easily damage other components inside the housing 100 and reduce their service life. Lining the inner wall of the door 130 with heat insulation material 240 prevents the door 130 and housing 100 from becoming too hot after heating, thus preventing injury to operators.

[0070] Furthermore, a connecting pipe 250 is also provided through the inner wall of the heating chamber 200. The connecting pipe 250 is used to connect the inside and outside of the heating chamber 200. The connecting pipe 250 is used to regulate the air pressure inside the heating chamber 200, and to connect the heating chamber 200 to the outside to prevent the air bag 700 from expanding during air intake, causing excessive pressure inside the heating chamber 200, and also to prevent insufficient pressure during exhaust, leading to incomplete exhaust. In other possible embodiments, the position of the connecting pipe 250 is not specifically limited, as long as it allows the inside of the heating chamber 200 to connect to the outside through the connecting pipe 250.

[0071] In this embodiment, the VOC detection device 610 is installed inside the housing 100. The VOC detection device 610 includes a display screen, which is located outside the housing 100. The VOC detection device 610 can detect the VOC concentration in the gas discharged from the gas bag 700 and display the VOC concentration each time it is discharged. By comparing the displayed data with national or local standards, it can be determined whether the gas bag 700 is properly cleaned, avoiding situations where the gas bag 700 is not properly cleaned or over-cleaned, thus improving the reliability of the gas bag 700 cleaning device.

[0072] Specifically, in this embodiment, the VOC detection device 610 is a VOC concentration detection sensor. In other possible embodiments, other detection devices can be selected, as long as they can detect and display the VOC concentration in the gas discharged from the gas bag 700.

[0073] Furthermore, the VOC adsorption device includes a housing 621 and a VOC adsorption material 622. An exhaust pipe 500 and an exhaust port 120 are respectively connected to the two sides adjacent to the opening of the housing 621. The adsorption material 622 is disposed inside the housing 621. The housing 621 structure of the VOC adsorption device facilitates the placement or replacement of the adsorption material 622 by the user. The connection to both sides of the housing 621 ensures that the emitted gas is filtered, preventing unfiltered emissions that could cause air pollution. In other possible embodiments, the VOC adsorption device can also be configured with other structures, such as a drawer-type structure or a box-like structure that can be opened and closed, as long as it allows the user to easily replace the adsorption material 622.

[0074] Specifically, the steps for using the Airbag 700 cleaning device are as follows:

[0075] Step S1: Place the air bag 700 inside the heating chamber 200 and connect it to the manifold 900, close the door 130 of the housing 100, and begin cleaning;

[0076] Step S2: The first solenoid valve 300 controls the connection between the manifold 900 and the exhaust pipe 500, and the air pump 510 discharges the gas in the air bag 700 until the air bag 700 is deflated.

[0077] Step S3: Turn on the heating device to heat up. At the same time, the first solenoid valve 300 controls the connection between the manifold 900 and the air inlet pipe 400 to flush nitrogen from the external nitrogen cylinder into the gas bag 700 until the gas bag 700 is full.

[0078] Step S4: Close the first solenoid valve 300, fill the air bag 700, and let it stand in the heating chamber 200 for a period of time to complete one cleaning cycle;

[0079] Step S5: Observe the display data of the VOC detection device 610, determine the cleanliness of the air bag 700, and choose to proceed with the next cycle or remove it directly from the heating chamber 200.
