Description

Technical Field

[0001] This invention relates to the field of smoke purification technology, specifically to a smoke purifier. Background Technology

[0002] As living standards improve, people's health awareness is gradually increasing, and their requirements for air quality are also rising. Numerous surveys and research data from professional institutions have proven that air pollution is a significant environmental factor contributing to the prevalence of respiratory and cardiovascular diseases. Smoke is a major form of air pollution. For example, industrial production, especially processes like welding, laser marking, and laser engraving, often generates large amounts of smoke. This smoke contains numerous toxic and harmful substances, causing not only environmental pollution but also harming people's health. Therefore, it is necessary to design smoke purification equipment to purify the smoke in the air and improve air quality. Summary of the Invention

[0004] To address the above problems, this invention provides a smoke purifier that can perform multi-stage purification of smoke.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smoke purifier includes multiple purification chambers. Each purification chamber has an inlet channel for absorbing gas and an outlet channel for discharging gas. The chamber contains a purification medium corresponding to the position of the inlet channel, allowing gas from the inlet channel to directly enter the purification medium and thus purify the smoke. The outlet channel is connected to a negative pressure component to create a negative pressure within the purification chamber, thereby driving the gas from the inlet channel to continuously pass through the purification medium. The inlet and outlet channels in different purification chambers can be interconnected, achieving multi-stage purification.

[0008] Preferably, the cleanroom comprises:

[0009] A purification bottle, with an opening at the top and an internal chamber for containing a purification medium;

[0010] The cover is detachably connected to the purification bottle and is used to cover the opening at the top of the purification bottle. The air inlet channel and the air outlet channel are both provided on the cover. There are various purification media. The purification media in the purification bottle can be replaced by opening and closing the cover.

[0011] Preferably, the purification chamber has two parts, namely a first purification chamber for absorbing gas and a second purification chamber connected to the negative pressure component. The air outlet of the first purification chamber and the air inlet of the second purification chamber are interconnected. The purification medium in the first purification chamber is water, and the purification medium in the second purification chamber is activated carbon, thereby achieving multi-media purification.

[0012] Preferably, it also includes a first pipe, the top of which is connected to the air intake channel on the first purification chamber, and the bottom of which is inserted into the water, so that the gas in the air intake channel on the first purification chamber can be directly introduced into the water. The side of the first pipe is provided with a plurality of first air outlets located in the water to increase the contact area between the gas and the water.

[0013] Preferably, the system also includes a tank, the top of which is connected to the air inlet channel of the second purification chamber, and contains activated carbon inside. The bottom is provided with multiple second air outlets so that the gas in the air inlet channel of the second purification chamber can be directly introduced into the activated carbon inside the tank. A first filter cotton is filled between the outside of the tank and the inside of the second purification chamber to filter the gas flowing from the second air outlet to the air outlet channel of the second purification chamber.

[0014] Preferably, the negative pressure component includes:

[0015] An air intake component is provided with an air intake pipe, which is connected to a positive pressure air source;

[0016] An air intake component is provided on the air inlet component, and an air intake pipe is provided therethrough.

[0017] An air outlet is provided on the air inlet and has an air outlet pipe that runs through it. The air outlet pipe is connected to the air intake pipe.

[0018] Preferably, it further includes a photo-oxidation purification component, which is disposed corresponding to the outlet end of the negative pressure component. The photo-oxidation purification component includes a UV lamp and a mounting bracket. The UV lamp is located on the mounting bracket and can emit ultraviolet light to catalytically oxidize the gas discharged from the outlet end of the negative pressure component, thereby decomposing the organic matter in the gas into water and carbon dioxide.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] In practical use, the air inlet and outlet channels of two adjacent purification chambers are connected to each other. Then, the negative pressure component on the outlet channel is activated, and negative pressure gradually forms in multiple purification chambers. This allows the gas outside the purification chamber to enter the purification medium in the first purification chamber through the air inlet channel at one end. This purification medium performs the first purification of the smoke in the gas. The purified gas then enters the next purification chamber through the outlet channel on the first purification chamber, and the above process is repeated until it is discharged from all purification chambers. Since the gas is purified by the corresponding purification medium in each purification chamber, the purification of the smoke in the gas is more thorough. Because the air inlet and outlet channels in different purification chambers can be interconnected, the number of times the gas is purified can be adjusted by adjusting the number of purification chambers. In summary, by using this smoke purifier, smoke can be purified in multiple stages. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] See appendix Figure 1 - Appendix Figure 14 This invention discloses a smoke purifier, comprising multiple purification chambers 1. Each purification chamber 1 is provided with an air inlet channel 2 for absorbing gas and an air outlet channel 3 for discharging gas. The chamber is equipped with a purification medium 4 corresponding to the position of the air inlet channel 2, so that the gas in the air inlet channel 2 can directly enter the purification medium 4, thereby purifying the smoke in the gas. The air outlet channel 3 is connected to a negative pressure component 5 to create a negative pressure in the purification chamber 1, thereby driving the gas in the air inlet channel 2 to continuously pass through the purification medium 4. The air inlet channels 2 and the air outlet channels 3 in different purification chambers 1 can be interconnected, thereby achieving multi-stage purification.

[0046] In practical use, the air inlet channel 2 and air outlet channel 3 of two adjacent purification chambers 1 are connected to each other. Then, the negative pressure component 5 on the air outlet channel 3 is activated. A negative pressure will gradually form in multiple purification chambers 1, allowing the gas outside the purification chamber 1 to enter the purification medium 4 in the first purification chamber 1 through the air inlet channel 2 at one end. The purification medium 4 will perform the first purification of the smoke in the gas. The purified gas enters the next purification chamber 1 through the air outlet channel 3 on the first purification chamber 1 and repeats the above process until it is discharged from all purification chambers 1. Since the gas is purified by the corresponding purification medium in each purification chamber, the purification of the smoke in the gas is more thorough. Since the air inlet channel 2 and air outlet channel 3 in different purification chambers 1 can be connected to each other, the number of times the gas is purified can also be adjusted by adjusting the number of purification chambers 1. In general, by using this smoke purifier, smoke can be purified in multiple stages.

[0047] See appendix Figure 1 and attached Figure 2 As the purification medium continuously purifies the smoke, its purification effect gradually weakens until it loses its effectiveness. However, the purification chamber and other components remain intact, and it would be wasteful to discard them directly. To address this issue, the following design is implemented in this embodiment. Specifically, the purification chamber 1 includes a purification bottle 1001 and a cover 1002. The purification bottle 1001 has an opening at the top and an internal chamber for containing the purification medium 4. The cover 1002 is detachably connected to the purification bottle 1001 and is used to close the opening at the top of the purification bottle 1001. The air inlet channel 2 and the air outlet channel 3 are both located on the cover 1002. There are various types of purification medium 4, and the purification medium 4 inside the purification bottle 1001 can be replaced by opening and closing the cover 1002.

[0048] Through the design of the above structure, not only can the purification medium 4 be removed and replaced after it becomes ineffective, so as to achieve the purpose of reuse, but also the type of purification medium 4 can be directly changed. The appropriate purification medium 4 can be selected according to the type of smoke to be purified, which can further enhance the purification effect and make it more flexible and convenient to use.

[0049] Furthermore, the detachable connection between the purification bottle 1001 and the cap 1002 is a threaded connection, which is simple in structure, easy to disassemble and assemble, and reliable in connection; sealing gaskets can also be set at corresponding parts of the purification bottle 1001 and the cap 1002 to enhance the overall sealing of the purification chamber 1.

[0050] See appendix Figure 1 - Appendix Figure 3To more clearly illustrate the multi-stage smoke purification process, the following design is implemented in this embodiment. Specifically, the purification chamber 1 has two chambers, namely a first purification chamber 1a for absorbing gas and a second purification chamber 1b connected to the negative pressure component 5. The air outlet channel 3 of the first purification chamber 1a and the air inlet channel 2 of the second purification chamber 1b are interconnected. The purification medium 4 in the first purification chamber 1a is water, and the purification medium 4 in the second purification chamber 1b is activated carbon, thereby achieving multi-media purification.

[0051] Based on the above scheme, taking the purification of fumes generated during soldering as an example, during use, the air inlet channel 2 on the first purification chamber 1a can be aligned with the soldering part. After the negative pressure component 5 is activated, a negative pressure is formed in the second purification chamber 1b and the first purification chamber 1a. The fumes generated during soldering will enter the water through the air inlet channel 2 on the first purification chamber 1a. The water dissolves the fumes in the gas, and the gas that has completed the first purification then enters the activated carbon through the air outlet channel 3 on the first purification chamber 1a and the air inlet channel 2 on the second purification chamber 1b. The activated carbon adsorbs the fumes in the gas, and the gas that has completed the second purification then exits the purification chamber 1b through the air outlet channel 3 on the second purification chamber 1b, thereby realizing multi-stage and multi-media purification of fumes in the gas.

[0052] Furthermore, an extension hose can be connected to the air intake channel 2 on the first cleanroom 1a, and the extension hose can be connected to the soldering equipment by means of bundling, so that its air intake can be changed according to the soldering part, making it more flexible to use; or a metal shaped hose can be used to fix its air intake in a designated position. If the metal shaped hose is connected to the soldering equipment, the spatial position of the soldering iron tip can also be maintained to assist the soldering operation.

[0053] See appendix Figure 2 and attached Figure 3 In order to enable the gas to directly enter the water through the air intake channel 2 on the first purification chamber 1a, the following design is made in this embodiment. Specifically, it also includes a first pipe 6. The top of the first pipe 6 is connected to the air intake channel 2 on the first purification chamber 1a, and the bottom is inserted into the water so that the gas in the air intake channel 2 on the first purification chamber 1a can be directly introduced into the water. The side of the first pipe 6 is provided with a plurality of first air outlets 61 located in the water to increase the contact area between the gas and the water.

[0054] In use, the bottom of the first pipe 6 can be closed or not. In order to make the flow rate of the gas column formed when the gas passes through the first outlet 61 faster, this embodiment takes the bottom of the first pipe 6 as closed as an example. At this time, the outside gas passes through the air inlet channel 2, the first pipe 6, and the first outlet 61 on the first purification chamber 1a in sequence and enters the water. Since the first outlet 61 is small in size, numerous and distributed in multiple directions on the side, the gas will make the water form a boiling effect after entering the water through the first outlet 61. Compared with only setting an opening at the bottom of the first pipe 6, the gas sprayed from multiple first outlets 61 forms smaller and more numerous bubbles in the water, and the contact with the water is more sufficient, so the purification effect is the best. In addition, the strength of the boiling effect can be controlled by changing the position, number, size and other parameters of the multiple first outlets 61.

[0055] Furthermore, this embodiment does not limit the shape, size, material, etc. of the first pipe 6, and can be flexibly selected according to actual needs. For example, the first pipe 6 can be set as a cylinder with a closed bottom and a constricted top. The first pipe 6 is connected to the air intake channel 2 on the first purification chamber 1a through the constricted top. At this time, the inner diameter of the first pipe 6 is significantly larger than the inner diameter of the air intake channel 2 on the first purification chamber 1a. Therefore, after the gas enters the larger first pipe 6 from the smaller air intake channel 2 on the first purification chamber 1a, the smoke concentration in the gas will be diluted and reduced. The size of the bubbles ejected from the first air outlet 61 remains unchanged, which makes each bubble carry less smoke components. Therefore, under the condition that other conditions remain unchanged, the method of small amount and multiple times can more fully and thoroughly purify the smoke in the bubbles.

[0056] The composition of smoke is usually quite complex, and a single purification medium 4 is often insufficient to completely purify it. To address this issue, the following design is implemented in this embodiment. Specifically, it also includes a tank 7. The top of the tank 7 is connected to the air inlet channel 2 on the second purification chamber 1b, and the tank 7 contains activated carbon. The bottom is provided with multiple second air outlets 71 so that the gas in the air inlet channel 2 on the second purification chamber 1b can be directly introduced into the activated carbon inside the tank 7. A first filter cotton 72 is filled between the outside of the tank 7 and the inside of the second purification chamber 1b to filter the gas flowing from the second air outlets 71 to the air outlet channel 3 of the second purification chamber 1b.

[0057] Through the above structural design, the gas purified by the purification medium 4 in the first purification chamber 1a will pass through the outlet channel 3 on the first purification chamber 1a and the inlet channel 2 on the second purification chamber 1b in sequence, and then enter the tank 7. The gas continuously enters from the top of the tank 7, causing the gas already in the tank 7 to continuously flow downward. Therefore, the gas will continuously flow through the activated carbon and be adsorbed and purified. The purified gas can then truly enter the second purification chamber 1b through the second outlet 71. Since the first filter cotton 72 is filled between the outside of the tank 7 and the inside of the second purification chamber 1b, the gas can undergo two smoke purifications in the second purification chamber 1b, resulting in a better purification effect.

[0058] See appendix Figure 1 - Appendix Figure 3 and appendix Figure 5 - Appendix Figure 7 There are various devices that can generate negative pressure, but during the process of filtering smoke, a large amount of impurities often accumulate and block the air supply pipes of the negative pressure device, making it impossible for the purification chamber 1 to generate negative pressure normally. In order to solve the above problems, the negative pressure component 5 in this embodiment uses a device that has solved the relevant problems in the prior art, namely, Chinese invention patent with patent number: CN202022618506.2 and title: A negative pressure suction device.

[0059] Based on the above scheme, the negative pressure component 5 includes an air inlet 51, an air intake 52, and an air outlet 53. The air inlet 51 is provided with an air intake pipe 511, which is connected to a positive pressure air source. The air intake 52 is provided on the air inlet 51, and it is provided with a through air intake pipe 521. The air outlet 53 is provided on the air inlet 51, and it is provided with a through air outlet pipe 531, which is connected to the air intake pipe 521. The air outlet 53 is also provided with multiple air holes 532, which are all connected to the air outlet pipe 531 and the air intake pipe 511. The ends of the multiple air holes 532 connected to the air outlet pipe 531 are all inclined towards the end of the air outlet 51 that is away from the air inlet 53.

[0060] Specifically, when using the negative pressure component 5, the user needs to obtain a power source through an external positive pressure gas device. When the positive pressure gas enters from the inlet pipe 511, it squeezes the air hole 532 and sprays it out to the outlet pipe 531, thereby increasing the gas flow rate in the outlet pipe 531. According to fluid mechanics, its atmospheric pressure decreases, forming a pressure difference with the outside atmosphere. Therefore, a negative pressure is formed, which draws outside air into the outlet pipe 531 through the suction pipe 521. This negative pressure can be used to suck up objects, and the objects are discharged from the outlet pipe 531, achieving the purpose of suction. This also prevents the sucked materials and dust from entering the inlet pipe 511 through the air hole 532, which would cause dust accumulation or blockage in the inlet pipe 511.

[0061] See appendix Figure 8 and attached Figure 9 Based on the above scheme, the smoke in the gas has been subjected to triple physical purification in this embodiment. Of course, biochemical purification can also be carried out by changing the type of purification medium 4. However, under the premise of the above scheme, the physical filtration in this embodiment can only remove solid impurities such as particulate matter and dust. It cannot effectively treat some volatile organic compounds and odors. In order to solve the above problems, the following design is made in this embodiment. Specifically, it also includes a photo-oxidation purification component 8. The photo-oxidation purification component 8 is set at the outlet end of the negative pressure component 5. It includes a UV lamp 81 and a mounting bracket 82. The UV lamp 81 is located on the mounting bracket 82 and can emit ultraviolet light to catalytically oxidize the gas discharged from the outlet end of the negative pressure component 5, thereby decomposing the organic matter in the gas into water and carbon dioxide.

[0062] Through the above structural design, the organic matter in the smoke can be decomposed into water and carbon dioxide by the ultraviolet light emitted by the UV lamp. Combining the above purification methods, this embodiment performs multi-stage, multi-media purification of the smoke, combining physical and biochemical purification, resulting in more thorough and effective purification of the smoke in the gas.

[0063] Furthermore, the ultraviolet rays emitted by UV lamps are harmful to the human body. To solve the above problem, the mounting bracket 82 can be made of opaque material to provide shielding in multiple directions, so as to prevent the ultraviolet rays emitted by UV lamps from directly irradiating the human body.

[0064] See appendix Figure 8 - Appendix Figure 10 To further enhance the purification effect, the following design is implemented in this embodiment. Specifically, the outlet of the negative pressure component 5 is connected to a filter component 9. The filter component 9 includes a bottle body 91, a third outlet 92, and a filter screen 93. The bottle body 91 is connected to the outlet of the negative pressure component 5. The third outlet 92 is located on the bottle body 91 and is set corresponding to the UV lamp 81. The filter screen 93 is located on the bottle body 91 and is set corresponding to the third outlet 92 to filter the gas passing through the third outlet 92.

[0065] Through the above structural design, not only can the smoke in the gas be purified again, but also the dust and other impurities in the outside air can be prevented from contaminating the outlet of the negative pressure component 5. In addition, since the third outlet 92 is set to correspond to the UV lamp 81, the gas ejected from the third outlet 92 can come into more full contact with the ultraviolet rays emitted by the UV lamp 81 and carry out photocatalytic oxidation reaction, resulting in better purification effect.

[0066] See appendix Figure 11 - Appendix Figure 14Since the above solution involves many components, it looks rather messy and is not easy to move. In order to solve the above problems, the following design is made in this embodiment. Specifically, it also includes a box 10, the purification chamber 1 and the negative pressure component 5 are both located inside the box 10. The box 10 is provided with an air inlet 101 for air intake and an air outlet 102 for air exhaust. The box 10 is provided with a switch 103 electrically connected to the negative pressure component 5 on the outside of the box 10 for controlling the start and stop of the negative pressure component 5. The box 10 is provided with a negative ion generator 104 for generating negative air ions, thereby purifying the gas inside the box 10.

[0067] Through the above structural design, the housing 10 can directly enclose multiple components, making it look more organized. In addition, the negative ion generator 104 can generate negative air ions, thereby freshening the air and eliminating smoke and dust. The gas that is finally discharged gives people a refreshing feeling when they absorb it.

[0068] Furthermore, an additional switch can be set to control the start and stop of the negative ion generator 104, or the start and stop of the negative ion generator 104 and the negative pressure component 5 can be controlled simultaneously by a single switch. Alternatively, a control panel 108 can be set to control and display parameters such as the power of the negative ion generator 104 and the negative pressure component 5. It should be noted that the above-mentioned control of the start and stop of the negative pressure component 5 specifically represents the control of the start and stop of the positive pressure air source connected to the air intake pipe 511.

[0069] To facilitate observation of the gas purification process, the following design was implemented in this embodiment: Specifically, the purification chamber 1 is made of transparent material, and the housing 10 is provided with an observation window 11 corresponding to the purification chamber 1, so as to directly observe the purification process of the gas in the purification chamber 1.

[0070] Furthermore, the housing 10 consists of two parts: an upper housing 105 and a lower housing 106. The upper housing 105 and the lower housing 106 are detachably connected. After the housing 10 is disassembled, the purification chamber 1 can be further disassembled to replace or clean the purification medium 4 inside. On this basis, the purification chamber 1, the negative pressure component 5, the air inlet 101, and the mounting bracket 82 are all installed on the upper housing 105, while the air outlet 102 is located on the lower housing 106. At this time, the mounting bracket 82 has a shape that is open from top to bottom and closed on the side. This not only facilitates the installation of other components but also blocks the ultraviolet rays emitted by the UV lamp. The opening at the top of the mounting bracket 82 is blocked by the upper housing 105, and the opening at the bottom of the mounting bracket 82 is roughly sealed by a shielding member 84 with a through hole 83. This further blocks the ultraviolet rays without affecting the entry and exit of the gas.

[0071] Furthermore, a second filter cotton 85 corresponding to the through hole 83 is provided on the shielding component 84, and a third filter cotton 107 corresponding to the air outlet 102 is provided on the lower housing 106. Primary filter cotton, medium-efficiency filter cotton, and high-efficiency filter cotton are selected as the first filter cotton 72, the second filter cotton 85, and the third filter cotton 107, respectively, which can improve the gas purification effect.

[0072] Furthermore, the upper housing 105 and the lower housing 106 are detachably connected by a snap-fit ​​connection. To facilitate the taking and placing of the upper housing 105, a handle 109 can be provided on the upper housing 105 so that the operator has a point of leverage when taking and placing the upper housing 105. When the negative pressure component 5 and the negative ion generator 104 are working, some noise will inevitably be generated. Therefore, wavy sound-absorbing cotton can be installed inside the mounting bracket 82 and the housing 10 respectively to achieve the purpose of noise reduction. Since the above structure is relatively simple, it is not shown in the attached drawings of the instruction manual.

[0073] Furthermore, casters 12 can be installed at the bottom of the housing 10 to make it easier to move the smoke purifier.

[0074] Based on the above scheme, the detachable connection method between the various components can be flexibly selected, such as threaded connection, snap-fit ​​connection or direct plug-in connection. However, it should be noted that since this smoke purifier is to purify the smoke in the gas, it is necessary to ensure the sealing between the various components. In some parts where the connection is not tight enough, sealing gaskets can be set to assist in sealing.

[0075] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0076] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
