[0002] In recent years, with the improvement of living standards, people have gradually paid attention to the air quality of the indoor environment, and products with indoor humidifying or / and oxygen-supplying functions have emerged as the times require. For example, in plateau areas, the indoor oxygen is improved through the oxygen enrichment project. Usually, in the industry, the oxygen of an oxygen supply device is generally transported to an oxygen-required environment through an oxygen supply channel to improve the oxygen content in the indoor oxygen-deficient environment, so as to strive to make the oxygen-rich amount in the environment meet the human body's needs. For example, a wall-mounted oxygen supply terminal is used to effectively adjust the oxygen in the room. Many air humidifying products have also been correspondingly introduced on the market.

[0030] It should be noted that the orientation terms such as "upper" and "lower" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limitations on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that a component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0031] It should be noted that the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusion.

[0032] Please refer to Figure 1A 、 Figure 1B 、 Figures 2 to 5, the indoor humidifying and oxygen supply regulator 100 of the present utility model is connected to a water source and an oxygen source, and includes a main body frame 1; a main housing 2 that is matched and installed with the main body frame 1, and an air inlet window 21 and an air outlet 22 are provided on the housing of the main housing 2;

[0033] A water supply pipe 3 connected to the water source;

[0034] A humidifying pipe 4 provided at the air inlet window 21 and fixed on the main body frame 1;

[0035] A humidifier 5 connected between the water supply pipe 3 and the humidifying pipe 4;

[0036] An axial flow fan 6 fixed on the main body frame 1, and the axial flow fan 6 is provided at the air outlet 22 of the main housing 2 and is located below the humidifying pipe 4;

[0037] An oxygen supply pipe 7 provided on the main body frame 1 and disposed opposite to the axial flow fan 6, and the oxygen supply pipe 7 is connected to the oxygen source.

[0038] After the main body frame 1 and the main housing 2 are installed, a receiving space (not marked in the figure) is formed, and the humidifying pipe 4 and the humidifier 5 are disposed in the receiving space.

[0039] The inlet end of the humidifying pipe 4 is connected to the steam outlet of the humidifier 5, and a plurality of humidifying ports (not marked in the figure) are provided at equal intervals along the extending direction of the pipe body of the humidifying pipe 4, and the humidifying ports (not marked in the figure) are disposed toward the axial flow fan 6 side. By providing a plurality of humidifying ports (not marked in the figure) arranged linearly at equal intervals on the humidifying pipe 4 and having a structure design toward the axial flow fan 6, on the premise of ensuring uniform fog output from the humidifying ports (not marked in the figure), through the disturbance of the axial flow fan 6 built in the receiving space, the purpose of uniformly sending out the humidifying steam from the air outlet 22 can be effectively achieved.

[0040] In a feasible embodiment, the humidifier 5 is disposed within the accommodation space formed by the main body frame and the main housing 2. In another feasible embodiment, the humidifier 5 may also be disposed outside the accommodation space formed by the main body frame 1 and the main housing 2. The indoor humidifying and oxygen supply regulator 100 shown in the exemplary embodiment of the present utility model has the humidifier 5 disposed within the accommodation space and the steam outlet of the humidifier 5 disposed close to one side of the humidifying port. Disposing the humidifier 5 within the accommodation space and the steam outlet of the humidifier 5 disposed close to one side of the humidifying port can maximize the assurance that when the steam generated within the humidifier 5 is sent into the accommodation space through the humidifying pipe 4, the problem of condensate formation due to the overly long pipe path does not occur. The exemplary embodiment shows a relatively reasonable technical solution in the case where no preheating device is installed on the humidifying pipe 4.

[0041] A heating sheet (not shown in the figure) is further attached to the pipe body of the humidifying pipe 4. When starting up until the humidifying function begins, the heating sheet (not shown in the figure) electrically connected to the controller preheats the humidifying pipe 4 to a set temperature T1, and the set temperature T1 should be greater than the steam temperature T2 of the humidifier 5. This method can effectively prevent the indoor humidifying and oxygen supply regulator 100 from having condensate formation within the humidifying pipe 4 at the initial stage of the humidifying function being turned on due to the pipe body temperature of the humidifying pipe 4 being lower than the steam temperature.

[0042] A slide-type back plate 8 is further provided on the main body frame 1, and a support arm 91 for supporting and fixing the humidifying pipe 4, which is movable and position-adjustable on the slide-type back plate 8, and a support frame 92 for supporting and fixing the humidifier 5, which is also disposed on the slide-type back plate 8 and position-adjustable, are further provided on the slide-type back plate 8. The slide-type back plate 8 is further provided with a fixing portion 81, and a fixing stud 111 corresponding to the fixing portion 81 is provided on the main body frame 1. The slide-type back plate 8 is fixed to the main body frame 1 through the mutual cooperation among screws (not shown in the figure), the fixing portion 81, and the fixing stud 111. The exemplary embodiment of the present utility model only exemplifies the screw fixing method. In other embodiments, other feasible methods such as using fixing intermediate members may be adopted, and other equivalent fixing structures should be included within the protection scope of this patent.

[0043] The indoor humidifying and oxygen supply regulator 100 further includes a drainage device 10 disposed below the axial flow fan 6. The drainage device 10 further includes a drainage trough 101 disposed on the main body frame 1 and below the axial flow fan 6 and the oxygen supply pipe 7, a drainage port 102 disposed at one end of the drainage trough 101 and communicating with the drainage trough 101, and a water seal pipe 13 that is substantially in an inverted "S" shape and connected between the drainage port 102 and a drain pipe (not shown in the figure). Further, the water inlet of the water seal pipe 13 is connected to the drainage port 102, and the drainage port 102 is higher than the water seal pipe 13 in the installation height direction of the indoor humidifying and oxygen supply regulator 100. It should be understood that the exemplary embodiment discloses a water seal pipe 13 in an inverted "S" shape, and in other feasible embodiments, a water seal pipe such as a "V" shape may be selectively adopted according to actual needs.

[0044] The drainage trough 101 and the drainage port 102 are of an integral structure. In a feasible embodiment, during specific installation, the end of the drainage trough 101 where the drainage port 102 is disposed is slightly lower than the end without the drainage port. A sewage outlet (not shown in the figure) is further provided on the water seal pipe 13.

[0045] An installation groove (not shown in the figure) for installing the oxygen supply pipe 7 is further provided on the main body frame 1 opposite to the axial flow fan 6. The pipe body of the oxygen supply pipe 7 is a uniform oxygen supply pipe designed according to the principle of constant static pressure throughout the length of the air duct. The pipe body gradually narrows along the length extension direction of the oxygen supply pipe 7, and a number of oxygen outlets (not marked in the figure) are arranged at equal intervals and in a straight line on the pipe body of the oxygen supply pipe 7. Adding the water seal pipe 13 in the drainage device 10 can effectively prevent the oxygen fed into the accommodation space from escaping through the drainage port 102 during the normal operation of the indoor humidifying and oxygen supply regulator 100. When the indoor humidifying and oxygen supply regulator 100 is working, due to the continuous operation of the axial flow fan and the continuous input of oxygen and / or steam into the main housing 2 as needed, the internal air pressure of the accommodation space is greater than the air pressure outside the accommodation space, and thus it is inevitable that the continuously input oxygen and / or steam inside the accommodation space overflows through the drainage port 102, reducing the humidifying and / or oxygen supply effect.

[0046] In a feasible embodiment, the oxygen supply pipe 7 and the air outlet 22 are on opposite sides of the axial flow fan 6.

[0047] In a specific embodiment, such as Figure 1A 、 Figure 1B 、 Figures 2 to 4As shown, the air inlet window 21 is provided on the top shell of the main housing 2, and the air outlet 22 is provided on the bottom shell of the main housing 2. The air inlet window 21 and the air outlet 22 are arranged in a vertically opposite structural layout, which is beneficial to form a gas flow corridor from top to bottom between the air inlet window 21 and the air outlet 22, so as to further ensure that the humidifying steam is stably sent out from the air outlet 22 when the axial flow fan 6 is running normally.

[0048] The indoor humidifying and oxygen supply regulator 100 further includes a front housing 11 detachably buckled on the main housing 2.

[0049] In a feasible embodiment, the humidifier 5 can be an ultrasonic humidifier. In other feasible embodiments, the humidifier 5 can also be a thermal evaporation type humidifier or a cold evaporation type humidifier, or an electrothermal humidifier. It should be known that due to the different selections of the humidifier 5, the heating sheet can be selectively mounted or not mounted on the humidifying pipe 4. For example, when an ultrasonic humidifier is selected as the humidifier, correspondingly, the heating sheet is matched and installed on the humidifying pipe 4; when an electrothermal humidifier is selected as the humidifier, the heating sheet does not need to be mounted on the humidifying pipe 4.

[0050] Furthermore, the humidifier 5 is installed in a fixed box 93 detachably mounted on the support frame 92.

[0051] It should be particularly noted that the first aspect of the claimed subject matter of the indoor humidifying and oxygen supply regulator 100 of the present invention lies in the positional relationship between the humidifying pipe 4, the oxygen supply pipe 7, and the axial flow fan 6 with respect to the air inlet window 21 and the air outlet 22.

[0052] The second aspect of the claimed subject matter of the indoor humidifying and oxygen supply regulator 100 of the present invention is to utilize and improve the existing wall-mounted air conditioner indoor unit to transform the existing wall-mounted air conditioner indoor unit into a regulator with humidifying and oxygen supply functions, so as to achieve the purpose of rapid productization. Of course, inevitably, while using the existing mature wall-mounted air conditioner indoor unit, some mature structures of the existing mature wall-mounted air conditioner indoor unit will be adopted or retained. For example, a detachable and washable dust-proof net provided at the air inlet window, a wind deflector provided at the air outlet, etc. are structures that can improve the product function. Compared with the existing mature wall-mounted air conditioner indoor unit, the indoor humidifying and oxygen supply regulator 100 of the present invention reduces the evaporator.

[0053] The third aspect of the claimed subject matter of the indoor humidifying and oxygen supply regulator 100 of the present utility model lies in that, when the indoor humidifying and oxygen supply regulator 100 is operating normally, the air pressure difference between the inside and outside of the accommodating space and the drainage device having the water seal structure can effectively prevent oxygen and / or steam from overflowing through the drainage port, thereby improving the humidifying and / or oxygen supply effect.

[0054] In a preferred embodiment, considering product safety, the oxygen source of the indoor humidifying and oxygen supply regulator 100 of the present utility model preferably uses oxygen-rich gas formed by mixing air and high-purity oxygen.

[0055] Please refer to Figure 6 and Figure 7 An indoor humidifying and oxygen supply regulating device 1000 according to a second aspect of the present utility model includes the indoor humidifying and oxygen supply regulator 100 according to the first aspect of the present utility model. The indoor humidifying and oxygen supply regulating device 200 further includes: a controller 12; a handheld control terminal 200 communicatively connected to the controller 201; a water source 300 for supplying water to the indoor humidifying and oxygen supply regulator 100 and an oxygen source 400 for supplying oxygen, and an electromagnetic valve 500 electrically connected to the controller 201 and disposed between the oxygen supply pipe and the oxygen source; the axial flow fan 6, the humidifier 5, and the electromagnetic valve 500 are all electrically connected to the controller 201 respectively.

[0056] In a feasible embodiment, at least a power-on / off control 201, a humidifying control 202, an oxygen supply control 203, and a wind speed control 204 communicatively connected to the controller 12 are provided on the handheld control terminal 200.

[0057] Please refer to Figures 6 to 8 In another feasible embodiment, the indoor humidifying and oxygen supply regulating device 1000 further includes a preheating control 205 provided on the handheld control terminal 200 and communicatively connected to the controller 12, and the heating sheet mounted on the humidifying pipe 4 is electrically connected to the controller 12.

[0058] In view of the problem of oxygen use safety, the present invention not only has a unique safety design in terms of structure, but also correspondingly introduces a safety control method in the diffused oxygen supply control method. Due to the problem of the protection object of the utility model patent, the technical solutions described in the present utility model do not specifically describe the safety control method. For example, considering function and safety, when implementing oxygen supply regulation, the axial flow fan 6 will be forcibly turned on together to avoid the accumulation of oxygen-rich gas in the accommodating space and at the same time facilitate timely oxygen supply to the oxygen-requiring space.

[0059] In summary, the indoor humidifying and oxygen supply regulator 100 and its device 1000 provided by the present utility model have a simple and practical structure, and can effectively adjust indoor humidification or / and oxygen supply on the premise of taking into account oxygen use safety.

[0060] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
