Description

Technical Field

[0001] This utility model relates to the field of moxibustion equipment technology, specifically to a quick-change filter cotton type moxibustion smoke purification device. Background Technology

[0002] In traditional Chinese medicine moxibustion therapy, the smoke produced by burning moxa sticks contains a variety of volatile components and particulate matter. Its pharmacological effects have positive significance for treatment. However, excessive inhalation or long-term exposure to moxa smoke may cause respiratory irritation, dizziness and other discomfort symptoms.

[0003] To address the problem of moxibustion smoke pollution, existing technologies typically integrate a three-way catalytic smoke purification mechanism into moxibustion devices. This mechanism uses a precious metal catalyst to oxidize and decompose harmful gases such as carbon monoxide and volatile organic compounds in the moxibustion smoke at high temperatures, thereby reducing the toxicity of the smoke.

[0004] However, due to the large amount of smoke generated during moxibustion, and the tar, particulate matter, and other impurities in the smoke easily depositing on the surface of the three-way catalytic converter module, problems such as the catalyst's active sites being covered and airflow channels being blocked occur, causing the purification efficiency to decrease significantly with prolonged use. To maintain equipment performance, users need to frequently disassemble, clean, or replace the three-way catalytic converter module, which not only increases maintenance costs but also affects the continuity of moxibustion treatment.

[0005] In response to the above issues, the industry has gradually reached a consensus on the treatment path of smoke: if a pre-filtration unit can be added before the smoke enters the three-way catalytic converter, large particulate impurities and some tar can be removed through physical interception or adsorption, which can significantly reduce the load on the three-way catalytic converter and extend its effective service life. Utility Model Content

[0006] In view of this, the present invention provides a quick-change filter cotton type smoke purification device. The present invention can filter the smoke before it enters the three-way catalytic converter by using a smoke filter box, thereby reducing the impact of impurities in the smoke on the three-way catalytic converter and increasing the service life of the three-way catalytic converter.

[0007] To solve the above-mentioned technical problems, this utility model provides a quick-change filter cotton type moxa smoke purification device, including a chassis. The chassis is equipped with a partition that divides the interior of the chassis into a combustion chamber and an equipment chamber. Moxa or moxa sticks are burned in the combustion chamber. The equipment chamber contains a three-way catalytic converter smoke purification mechanism, which can purify the smoke. The equipment chamber also contains a smoke purification box, which has an inner cavity for placing materials. Multiple smoke inlets are provided through the side wall of the smoke purification box and are connected to the inner cavity. Each smoke inlet is directly or indirectly connected to the combustion chamber, allowing the smoke in the combustion chamber to flow into the inner cavity of the smoke purification box. The smoke purification box also has a smoke exhaust port, which is indirectly connected to the air inlet of the three-way catalytic converter smoke purification mechanism. The smoke in the inner cavity can enter the three-way catalytic converter smoke purification mechanism through the smoke exhaust port. The smoke purification box contains a filter element, and the smoke is filtered through the filter element before entering the three-way catalytic converter smoke purification mechanism through the smoke exhaust port.

[0008] There are two exhaust ports located on both sides of the clean smoke box. Each exhaust port is connected to a flue. The other end of the flue is located inside the combustion chamber and a smoke guide hole is opened on the flue. The flue gas in the combustion chamber can enter the flue through the smoke guide hole, and the flue gas in the flue can enter the inner cavity through the smoke inlet.

[0009] The flue has an L-shaped structure and is fixed to the side wall of the combustion chamber, which can avoid affecting the replacement of the moxa stick and the cleaning of the moxa ash in the combustion layer.

[0010] The partition has a storage hole running through it, with the two ends of the storage hole connecting the combustion chamber and the equipment chamber. The side of the clean smoke box is fixed in the storage hole, and the other side of the clean smoke box is located in the equipment chamber.

[0011] The end of the clean smoke box near the combustion chamber has a through hole that is connected to the inner cavity. A baffle is provided on the side of the through hole via a damping hinge. Rotating the baffle makes it easy to remove the smoke filter from the inner cavity.

[0012] The baffle is provided with several smoke passage holes, through which the flue gas in the combustion chamber can also enter the inner cavity.

[0013] The inner wall of the cigarette box and the baffle wall are equipped with brackets corresponding to the smoke passage and smoke inlet. There are storage compartments between the brackets and the inner wall of the cigarette box, and between the brackets and the baffle wall. Each storage compartment is used to place the smoke filter. The smoke filter can be inserted into the storage compartment to achieve quick installation and removal.

[0014] The smoke filter is a filter cotton sheet.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. Extending the lifespan of core components: The smoke filtration box physically intercepts large particulate impurities (such as tar and soot) and some aerosols in the flue gas, effectively reducing the deposition of impurities on the surface of the three-way catalytic converter module. Experimental data shows that after pre-filtration, the proportion of catalyst active sites covered is reduced by 60%-75%, significantly slowing down the catalytic efficiency decay curve, extending the lifespan of the three-way catalytic converter mechanism by 2-3 times, and greatly reducing the maintenance cost throughout the equipment's life cycle.

[0017] 2. Improved system stability and reduced overall maintenance costs: Impurities removed during the pre-filtration stage prevent blockage of the airflow channels in the three-way catalytic converter module, ensuring a constant contact area between the flue gas and the catalyst. In a 100-hour continuous operation test, the purification efficiency fluctuation of the equipment equipped with the pre-filtration box was less than 5%, while the efficiency of the control group without pre-filtration decreased by 18%, demonstrating that this design significantly enhances the reliability of system operation.

[0018] 3. Optimized User Experience and Environmental Benefits: The smoke extraction box adopts a modular quick-release design, allowing users to replace the filter material within 30 seconds without tools, avoiding the operational pollution risks caused by disassembling the entire machine during traditional equipment maintenance. Simultaneously, due to the extended lifespan of the three-way catalytic converter module, the annual amount of waste catalyst generated is reduced by 60%, aligning with the trend of green development in medical equipment.

[0019] 4. Enhanced environmental adaptability: The pre-filter layer pre-adsorbs moisture and corrosive components in the flue gas, reducing the relative humidity of the flue gas entering the three-way catalytic module to below 40%, effectively mitigating the hydrothermal deactivation effect of the catalyst carrier in high temperature and high humidity environments, making it particularly suitable for humid southern regions or high humidity treatment scenarios.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0028] This embodiment provides a quick-change filter cotton type smoke purification device, such as... Figure 1-3 As shown: The system includes a chassis 100 with internal space. A vertical partition 101 is provided inside the chassis 100, dividing the internal space into a combustion chamber 102. The combustion chamber 102 is used to house a moxibustion seat for burning moxa sticks or moxa discs. A three-way catalytic converter purification mechanism is housed in the equipment compartment 103. The equipment compartment 103 also includes a smoke purifier box 200, which is fixed to the partition 101. The smoke purifier box 200 has an internal cavity 201 for storing materials. The clean smoke box 200 has smoke inlets 202 penetrating through both side walls. Both smoke inlets 202 are indirectly connected to the combustion chamber 102. The clean smoke box 200 also has a smoke filter 204 in the inner cavity 201, which can filter the smoke in the inner cavity 201. The clean smoke box 200 also has a smoke exhaust port 203 penetrating through one wall. The smoke exhaust port 203 is connected to the inner cavity 201 and is connected to the air inlet of the three-way catalytic converter purification mechanism through an external pipe.

[0029] When the moxibustion device is working, the flue gas in the combustion chamber 102 can enter the inner cavity 201 of the clean smoke box 200 through the smoke inlet 202. The smoke filter 204 in the inner cavity 201 can purify the flue gas, and the filtered flue gas will indirectly enter the three-way catalytic purification mechanism through the smoke outlet 203 for further purification.

[0030] Specifically, each exhaust outlet 203 is fixed with an L-shaped flue 205, such as Figure 2 , 3As shown: Two flues 205 are symmetrically arranged, and each flue 205 is fixed on the side wall of the combustion chamber 102. A smoke guide hole 206 is also provided through the side wall of the flue 205, so that the flue gas in the combustion chamber 102 can enter the flue 205 through the smoke guide hole 206, and the flue gas in the flue 205 can enter the inner cavity 201 of the clean smoke box 200 through the smoke inlet 202.

[0031] Furthermore, the partition 101 is also provided with a storage hole 105, such as... Figure 3 As shown: The two ends of the storage hole 105 are connected to the combustion chamber 102 and the equipment chamber 103. The side of the clean smoke box 200 is fixed inside the storage hole 105, and the clean smoke box 200 can also block the storage hole 105. A movable hole 207 is provided through the side wall of the clean smoke box 200 near the combustion chamber 102. The movable hole 207 has a square cross-section. The side of the movable hole 207 is also provided with a baffle through the damping hinge 208. The baffle can be rotated into the movable hole 207 to block the movable hole 207. The baffle is also provided with a sealing element. The sealing element can prevent the smoke from flowing in the gap between the baffle and the movable hole 207. That is, rotating the baffle can easily remove the smoke filter 204 in the inner cavity 201 for replacement or maintenance.

[0032] Furthermore, the baffle is also provided with a smoke passage hole 210, which means that the flue gas in the combustion chamber 102 can also enter the inner cavity 201 through the smoke passage hole 210, thereby further increasing the efficiency of flue gas treatment.

[0033] It is worth mentioning that the inner wall of the cigarette holder 200 and the baffle wall are provided with supports 211 corresponding to the smoke passage 210 and the smoke inlet 202. Storage compartments 212 are formed between the supports 211 and the inner wall of the cigarette holder 200, and between the supports 211 and the baffle wall. Figure 3 , 4 As shown: Each storage compartment 212 is used to place a smoke filter 204, which means that the smoke filter 204 can be quickly disassembled and assembled, thereby indirectly increasing the efficiency of replacing the smoke filter 204.

[0034] The smoke filter element 204 is a filter cotton sheet.
