Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire protection equipment, and particularly relates to a detachable oxygen generation tank. BACKGROUND

[0002] The oxygen generation tank in the prior art is disposable, so that the entire oxygen generation tank is scrapped after the internal medicament is used up, which is a great waste of social resources and increases a large amount of cost.

[0003] Meanwhile, the medicament in the disposable oxygen generation tank cannot be taken out for treatment, which greatly pollutes the environment.

[0004] In addition, the existing oxygen generation medicament is dry and in the form of tablets, and there are gaps between the tablets. In the early stage of the oxygen generation process, the gas can flow through the gaps. However, as the oxygen generation medicament reacts, the tablet-shaped oxygen generation medicament will gradually gather to form a large amount of viscous block-shaped medicament, so that the gaps between the viscous block-shaped medicaments greatly hinder the flow of the gas. The air at the input end of the traditional oxygen generation tank can only be introduced into the oxygen generation medicament from above the air inlet port, so that the contact surface between the gas and the oxygen generation medicament is small, and the overall reaction path of the oxygen generation medicament is long, which leads to a slow oxygen generation reaction rate. SUMMARY

[0005] In view of the above analysis, the present application aims to provide a detachable oxygen generation tank to solve the problems of the disposable oxygen generation tank in the prior art, such as waste of resources and low oxygen generation rate.

[0006] The main purpose of the present application is achieved by the following technical solutions:

[0007] A detachable oxygen generation tank comprises an air inlet module, an oxygen generation tank inner cylinder, an inner cylinder support, an oxygen generation tank outer cylinder and an air outlet module. The oxygen generation tank inner cylinder is sleeved in the oxygen generation tank outer cylinder, and the inner cylinder support is sleeved in the oxygen generation tank inner cylinder, thereby forming an oxygen generation tank cylinder. The air inlet module is detachably arranged above the oxygen generation tank cylinder and used for sealing the top of the oxygen generation tank cylinder and serving as a gas input end. The air outlet module is arranged below the oxygen generation tank cylinder and serves as an oxygen output end.

[0008] Further, the air inlet module comprises an air inlet cover and a sealing rubber ring.

[0009] Further, the air inlet cover comprises an air inlet, a cover eave and a limiting ring.

[0010] Further, the sealing rubber ring is arranged in an annular groove between the cover eave and the limiting ring.

[0011] Further, the oxygen generation tank inner cylinder comprises a plurality of isolation parts which are uniformly distributed on the cylinder wall of the oxygen generation tank inner cylinder.

[0012] Further, the diameter of the isolation part is greater than the wall thickness of the oxygen generation tank inner cylinder.

[0013] Further, the oxygen generation tank inner cylinder further comprises a fastener capable of being detachably connected with the isolation part.

[0014] Further, the inner cylinder support comprises a support isolation plate.

[0015] Further, an air inlet filter module is further included, which comprises a first porous support plate, filter cotton, a second porous support plate, a first filter screen and a second filter screen.

[0016] Further, the air outlet module comprises an air outlet, an air outlet filter cartridge and an oxygen candle.

[0017] Compared with the prior art, the present application can achieve at least one of the following beneficial effects:

[0018] (1) The upper end of the oxygen generation tank cylinder of the detachable oxygen generation tank is detachably provided with an air inlet module; the upper end is detachably provided with an air outlet module; and the oxygen generation tank outer cylinder, the oxygen generation tank inner cylinder and the inner cylinder support are detachably connected. In use, the oxygen generation tank outer cylinder, the oxygen generation tank inner cylinder and the inner cylinder support are combined, the air outlet module is fixed to the lower end of the oxygen generation tank cylinder, the oxygen generation reagent is placed in the inner cylinder support, and finally the oxygen generation tank cylinder is sealed with the air inlet module, so that it can be used. When the internal reagent is used up, the air inlet module is removed from the oxygen generation tank, the reacted oxygen generation reagent is poured out, and other parts are disassembled for cleaning and drying, so that it can be used for the next use. The detachable structure realizes the reuse of the oxygen generation tank, and only the internal oxygen generation reagent needs to be replaced for repeated oxygen generation, which greatly reduces the use cost, and for the existing integrated oxygen generation tank, the detachable oxygen generation tank of the present application can take out the internal oxygen generation reagent for treatment, reducing the pollution of the reagent to the environment.

[0019] (2) The oxygen generation tank inner cylinder comprises an isolation part and a fastener, the isolation part is provided in plurality and uniformly distributed on the cylinder wall of the oxygen generation tank inner cylinder. The isolation part is a cylindrical through hole, and the fastener can pass through a sealing rubber ring to be fixedly connected with the isolation part, realizing the detachable function of the oxygen generation tank.

[0020] (3) The inner wall of the isolation part of the application protrudes from the inner wall of the oxygen tank inner cylinder, and the outer wall of the isolation part protrudes from the outer wall of the oxygen tank inner cylinder. The setting of the isolation part makes the outer wall of the isolation part fit the inner wall of the oxygen tank outer cylinder when the oxygen tank inner cylinder is sleeved on the oxygen tank outer cylinder, and the outer wall of the oxygen tank inner cylinder between adjacent isolation parts and the inner wall of the oxygen tank outer cylinder form a phase change material containing space. The phase change material containing space can be filled with temperature phase change material to absorb the high temperature generated during the reaction inside the oxygen tank, thereby reducing the temperature of the gas inside the oxygen tank and improving the comfort of breathing.

[0021] (4) The inner cylinder support of the application is sleeved in the oxygen tank inner cylinder, and the outer wall of the isolation part fits the outer wall of the inner cylinder support, so that the inner wall of the oxygen tank inner cylinder between adjacent isolation parts and the outer wall of the inner cylinder support form a gas flow space. When the gas enters from the gas inlet module, the gas not only enters the internal oxygenation medicament from above the inner cylinder support, but also flows into the gas flow space, so that the gas can flow into the oxygenation medicament in the inner cylinder support from the entire outer wall of the inner cylinder support. The design of the gas flow space greatly reduces the reaction path of the input gas and the oxygenation medicament, significantly increases the contact area of the gas and the oxygenation medicament, greatly reduces the flow resistance of the gas, improves the oxygenation reaction rate, and further improves the comfort of breathing.

[0022] (5) The isolation part of the oxygen tank inner cylinder of the application includes a plurality of sleeved isolation plates, which are arranged in parallel with each other and connected by nesting in a clamping manner. During use, the cross-sectional size of the isolation part of the oxygen tank inner cylinder can be increased or decreased by simply disassembling and assembling the isolation plates, that is, the gap size of the gas flow space and the phase change material containing space can be adjusted to meet different needs.

[0023] (6) The inner cylinder support of the application is a meshed circular tube support, and a plurality of hollow holes are uniformly arranged on the entire wall surface of the circular tube support, so that the input gas can flow in from above and the side wall of the inner cylinder support, and the reaction area of the gas and the oxygenation medicament is increased. In addition, it is worth noting that the diameter of the hollow hole on the side wall of the inner cylinder support is smaller than the particle size of the flaky oxygenation medicament, so that the oxygenation medicament will not fall out of the hollow hole. At the same time, the diameter of the hollow hole is equal to the diameter of the bolt for fixing the support isolation plate, so that the bolt can pass through the hollow hole, and the bolt can limit the position of the hollow hole, thereby limiting and fixing the support isolation plate fixed by the bolt.

[0024] In the application, the above-mentioned technical solutions can be combined with each other to realize more preferred combination schemes. Other features and advantages of the application will be described in the subsequent description, and some advantages will become apparent from the description or will be understood by implementing the application.

[0040] The detachable oxygen generator tank is further described in detail below in combination with specific embodiments, which are only used for comparison and explanation purposes, and the present application is not limited to these embodiments.

[0041] In one specific embodiment of the present application, a detachable oxygen generator tank is disclosed, as shown in Figure 1 and Figure 2 which comprises an air inlet module 1, an oxygen generator inner cylinder 3, an inner cylinder support 4, an oxygen generator outer cylinder 5, and an air outlet module 6. The oxygen generator inner cylinder 3 is sleeved on the inner wall of the oxygen generator outer cylinder 5, and the inner cylinder support 4 is sleeved on the inner wall of the oxygen generator inner cylinder 3. The oxygen generator inner cylinder 3, the inner cylinder support 4, and the oxygen generator outer cylinder 5 are coaxially arranged to form an oxygen generator cylinder with an open upper end capable of containing oxygen generation reagents. The air inlet module 1 is detachably arranged above the oxygen generator cylinder to seal the top of the oxygen generator cylinder and serve as the gas input end during use. The air outlet module 6 is detachably arranged below the oxygen generator cylinder to serve as the oxygen output end during use.

[0042] In implementation, the oxygen generator outer cylinder 5, the oxygen generator inner cylinder 3, and the inner cylinder support 4 are sequentially combined from the outside to the inside to form the oxygen generator cylinder. The air outlet module 6 is fixed to the lower end of the oxygen generator cylinder, the oxygen generation reagents are placed in the inner cylinder support 4, and finally the air inlet module 1 is used to seal the oxygen generator cylinder, which can be used.

[0043] When the internal reagents are used up, the air inlet module 1 is removed from the oxygen generator tank, the reacted oxygen generation reagents are poured out, and the oxygen generator outer cylinder 5, the oxygen generator inner cylinder 3, the inner cylinder support 4, and the air outlet module 6 are disassembled for cleaning and drying, which can be used for the next use. The detachable structure realizes the reuse of the oxygen generator tank, and only the internal oxygen generation reagents need to be replaced for repeated oxygen generation, which greatly reduces the use cost. At the same time, for the existing integrated oxygen generator tank, the detachable oxygen generator tank of the present application can take out the internal oxygen generation reagents for treatment, which reduces the pollution of the reagents to the environment.

[0044] Further, as shown in Figure 3 the air inlet module 1 comprises an air inlet cover 11 and a sealing rubber ring 12.

[0045] Further, as shown in Figure 4As shown, the air inlet cover 11 includes an air inlet 111, a cover eave 112 and a limiting ring 113. The air inlet 111 is arranged in the middle of the upper surface of the air inlet cover 11, which is the gas inlet for the oxygen generator tank during the working process. The cover eave 112 is circumferentially arranged at the edge of the air inlet cover 11, and the inner wall diameter of the cover eave 112 is equal to the outer wall diameter of the outer cylinder 5 of the oxygen generator tank. When the air inlet cover 11 is combined with the cylinder cover of the oxygen generator tank, the cover eave 112 can be perfectly fitted with the outer wall of the outer cylinder 5 of the oxygen generator tank. The limiting ring 113 is arranged on the lower surface of the air inlet cover and coaxial with the air inlet 111. An annular groove is formed between the limiting ring 113 and the cover eave 112, which is used to place the sealing rubber ring 12.

[0046] Specifically, the sealing rubber ring 12 is detachably arranged in the annular groove. The positioning of the annular groove to the sealing rubber ring 12 makes it convenient to install the sealing rubber ring 12 every time it is replaced.

[0047] Further, as shown, Figures 3-4 The inner cylinder 3 of the oxygen generator tank includes isolation portions 31 and fasteners 32. The isolation portions 31 are arranged in multiple and uniformly distributed on the cylinder wall of the inner cylinder 3 of the oxygen generator tank. The isolation portions 31 are provided with fastening holes above. When the oxygen generator tank is sealed, the fasteners 32 can pass through the sealing rubber ring 12 and be fixedly connected with the fastening holes on the isolation portions 31, realizing the detachable function of the oxygen generator tank.

[0048] Preferably, the fasteners 32 can be screws, which are fixedly connected with the threads on the inner wall of the isolation portions 31.

[0049] It is worth noting that one side of the isolation portion 31 protrudes from the inner wall of the inner cylinder 3 of the oxygen generator tank, forming a part protruding inward, while the other side of the isolation portion 31 protrudes from the outer wall of the inner cylinder 3 of the oxygen generator tank, forming a part protruding outward.

[0050] Further, the outward protruding part of the isolation portion 31 makes the outer wall of the isolation portion 31 fit with the inner wall of the outer cylinder 5 of the oxygen generator tank when the inner cylinder 3 of the oxygen generator tank is sleeved on the outer cylinder 5 of the oxygen generator tank, so that the outer wall of the inner cylinder 3 between the outer sides of adjacent isolation portions 31 and the inner wall of the outer cylinder 5 of the oxygen generator tank form a phase change material containing space 51. The phase change material containing space 51 can be filled with temperature phase change substances, which are used to absorb the high temperature generated during the reaction inside the oxygen generator tank, thereby reducing the temperature of the gas inside the oxygen generator tank and improving the comfort of breathing.

[0051] Preferably, each outer side isolation portion 31 is provided with a flow channel or a flow hole, and the flow channel or the flow hole is arranged in multiple, which is used for heat exchange and transmission or flow of the phase change material between adjacent phase change material containing spaces 51.

[0052] When the oxygen generator tank is working, the phase change material absorbs heat, and the heat of the plurality of phase change material containing spaces 51 is uneven, and efficient heat exchange transmission can be performed through the flow-through grooves or flow-through holes, so that the heat of the phase change material containing space 51 can be quickly balanced.

[0053] Optionally, when the oxygen generator tank is working, the phase change material in the plurality of phase change material containing spaces 51 can flow through the flow-through grooves or flow-through holes, so that the temperature of the phase change material in the plurality of phase change material containing spaces 51 is balanced, and excessive heat accumulation is avoided.

[0054] Further, the inner cylinder support 4 is sleeved in the oxygen generator tank inner cylinder 3, and the gas flow-through space 41 is formed between the portion protruding outward of the adjacent isolation portion 31 of the oxygen generator tank inner cylinder 3 and the outer wall of the inner cylinder support 4.

[0055] Since the inner cylinder support 4 is filled with sheet-shaped oxygen generation medicaments, there are gaps between the dry sheet-shaped oxygen generation medicaments, and the gas can flow through the gaps in the early stage. However, during the oxygen generation reaction process, the sheet-shaped oxygen generation medicaments will gradually aggregate to form a large amount of viscous block-shaped medicaments, so that the gaps between the viscous block-shaped medicaments greatly hinder the flow of the gas. The air at the input end of the traditional oxygen generator tank can only be introduced into the oxygen generation medicaments from above the air inlet port, so that the contact area between the gas and the oxygen generation medicaments is small, and the overall reaction path of the oxygen generation medicaments is long, which leads to a slow oxygen generation reaction rate.

[0056] The gas flow-through space 41 can well solve the above problems, as shown in FIG. Figure 5 When the gas enters from the air inlet module 1, the gas not only enters the internal oxygen generation medicaments from above the inner cylinder support 4, but also enters the gas flow-through space 41, so that the gas can flow into the oxygen generation medicaments in the inner cylinder support 4 from the entire outer wall of the inner cylinder support 4. The reaction path of the input gas and the oxygen generation medicaments is greatly reduced, the contact area between the gas and the oxygen generation medicaments is obviously increased, the flow resistance of the gas is greatly reduced, the oxygen generation reaction rate is improved, and the comfort of breathing is improved again.

[0057] Preferably, the gas flow-through channel or gas flow-through hole is arranged on each inner side isolation portion 31, and the gas flow-through channel or gas flow-through hole is provided with one or more, so that the gas flowing into the adjacent gas flow-through space 41 can flow and exchange with each other, further reducing the flow resistance of the gas and improving the oxygen generation reaction rate.

[0058] It is worth noting that the isolation portion 31 of the oxygen generator tank inner cylinder 3 in the present application includes a plurality of sleeved isolation plates, and the plurality of isolation plates are connected in a clamping manner. During use, the cross-sectional size of the isolation portion 31 of the oxygen generator tank inner cylinder 3 can be increased or decreased by only disassembling and assembling the isolation plates, that is, the gap size between the gas flow-through space 41 and the phase change material containing space 51 can be adjusted to adapt to different needs.

[0059] Further, as shown in Figure 6 The inner cylinder support 4 includes a plurality of support isolation plates 42, which are evenly arranged vertically on the inner wall surface of the inner cylinder support 4. The side of the support isolation plate 42 in contact with the inner cylinder support 4 is provided with a fixing piece, which is arranged vertically with the support isolation plate 42. The fixing piece is fixed to the inner cylinder support 4 by a bolt passing through the through hole of the fixing piece.

[0060] Further, the inner cylinder support 4 is a meshed circular tube support, and a plurality of hollow holes are evenly arranged on the entire wall surface of the circular tube support, so that the input gas can flow in from the top and the side wall of the inner cylinder support 4, increasing the reaction area of the gas and the oxygen-generating agent.

[0061] Specifically, the diameter of the hollow hole on the side wall of the inner cylinder support 4 is smaller than the particle size of the sheet-shaped oxygen-generating agent, so that the oxygen-generating agent will not fall out of the hollow hole. At the same time, the diameter of the hollow hole is equal to the diameter of the bolt for fixing the support isolation plate, so that the bolt can pass through the hollow hole, thereby limiting the bolt and fixing the support isolation plate 42 fixed by the bolt.

[0062] Further, it further includes an air inlet filtering module 2, which is detachably arranged on the lower wall surface of the air inlet module 1.

[0063] Specifically, as shown in Figure 7 The air inlet filtering module 2 includes, from one end close to the air inlet module 1 to one end away from the air inlet module 1, a first porous support plate 21, a filter cotton 22, a second porous support plate 23, a first filter screen 24 and a second filter screen 25.

[0064] The filter cotton 22 is used to filter large particles in the input gas; the first porous support plate 21 and the second porous support plate 23 are used to support the filter cotton 22; and the first filter screen 24 is a filtering medium for the next step.

[0065] In addition, the second filter screen 25 is the last filtering medium, which is an elastic filter layer directly contacting the oxygen-generating agent, has small and dense filter apertures, and has the effect of preventing the oxygen-generating agent in the inner cylinder support 4 from overflowing out through the air inlet filtering module 2 in addition to the filtering effect of the last layer.

[0066] Specifically, the apertures of the filter plates are arranged from large to small, i.e., the first porous support plate 21, the second porous support plate 23, the first filter screen 24 and the second filter screen 25, and the density of the meshes is arranged from sparse to dense.

[0067] It is worth noting that, as shown in Figure 8As shown, the first filter screen 24 not only has a filtering effect, but also plays a role in height adjustment of the entire air intake filter module 2. Specifically, the first filter screen 24 is uniformly provided with a plurality of downward convex rib structures, which can compact the oxygen-generating reagent in the inner cylinder support 4, avoiding the oxygen-generating reagent being too loose.

[0068] Optionally, the height of the convex rib structure in the first filter screen 24 is adjustable, which can be adjusted according to the amount of oxygen-generating reagent in the inner cylinder support 4.

[0069] Specifically, the convex rib structure is a multi-stage nested convex rib structure, and adjacent nested convex ribs are connected by snap-fit or interference fit. By adjusting the nested convex ribs, the overall height of the convex rib structure is adjusted.

[0070] Further, as shown, Figure 9 The air outlet module 6 includes an air outlet 61, an air outlet filter cartridge 62, and an oxygen candle 63. The air outlet 61 and the air outlet filter cartridge 62 are coaxially arranged on both sides of the bottom plate, and the air outlet filter cartridge 62 is provided with a filter layer for filtering the output gas and preventing the oxygen-generating reagent in the inner cylinder support 4 from entering the air outlet module 6. The oxygen candle 63 is arranged on the bottom plate and is on the same side as the air outlet filter cartridge 62, serving as a generator for initial oxygen production.

[0071] Specifically, the bottom of the oxygen tank outer cylinder 5 is provided with a through hole corresponding to the air outlet filter cartridge 62 and the oxygen candle 63, so that the air outlet module 6 and the oxygen tank outer cylinder 5 can be connected, and the two are fixedly connected by fasteners.

[0072] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed by the present application can be easily thought of by those skilled in the art, and should be covered within the protection scope of the present application.
