Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oxygen concentrators, in particular to an oxygen concentrator with an integral heat dissipation air duct. Background Art
[0002] Oxygen generator is a device used to produce oxygen. Its principle is mainly based on air separation technology. It compresses air and uses the difference in condensation points of various components in the air to separate gas and liquid at a specific temperature, and then separates oxygen and nitrogen through steps such as distillation.
[0003] Since the booster pump of the oxygen concentrator generates a lot of heat during operation, heat dissipation technology is an indispensable part of the design of the oxygen concentrator. The heat dissipation performance of the oxygen concentrator directly affects its working efficiency and stability. If the heat dissipation is poor, the internal temperature of the oxygen concentrator will rise, thus affecting its normal operation and even damaging the equipment.
[0004] As described in the Chinese patent application with publication number CN106744695A, the existing oxygen concentrator has a heat dissipation fan arranged inside the oxygen concentrator, so that air enters from the upper part of the oxygen concentrator and is then discharged from the lower part of the same side. This spatial design results in poor heat dissipation effect on the back side of the oxygen concentrator. At the same time, since the density of hot air is less than that of cold air, hot air tends to rise, causing part of the hot air to rise inside the oxygen concentrator before reaching the heat dissipation port at the bottom of the oxygen concentrator, resulting in poor heat dissipation effect. Utility Model Content
[0005] The utility model aims to provide an oxygen concentrator with an integral heat dissipation air duct, which can efficiently dissipate heat in the entire oxygen concentrator.
[0006] In order to solve the above technical problems, the utility model adopts the following solutions:
[0007] An oxygen concentrator with an integral heat dissipation air duct comprises a shell, a heat dissipation fan and a booster pump are arranged in the shell, the shell comprises a top cover, a front cover plate, and a bottom cover arranged in sequence from top to bottom, the heat dissipation fan is arranged near the top cover, the booster pump is arranged near the bottom cover, an air inlet is arranged on the bottom cover, an air outlet is arranged on the upper side of the front cover plate, and an air guide plate for guiding the air entering the shell from the air inlet to the middle of the shell is arranged on the bottom cover. Its function is that, through the design of the positions of the air inlet, the air outlet and the heat dissipation fan, cold air enters the shell from the lower side of the shell to dissipate heat to the space in the shell, the cold air becomes hot air in the process of dissipating heat to the booster pump, the hot air directly rises to the heat dissipation fan and is blown to the air outlet for discharge, which can effectively reduce the residual time of hot air in the shell, and has a good heat dissipation effect; through the arrangement of the air guide plate, the cold air can be guided to the middle of the shell, so that the whole inside the shell can be dissipated, and the overall heat dissipation effect is good.
[0008] Furthermore, the air inlet is arranged at the front side of the bottom cover, and the air guide plate includes an air receiving portion corresponding to the air inlet and an air guide portion for guiding the air to the middle of the shell, and the air guide portion is in the shape of a curved surface convex toward the surface where the air inlet is located. Its function is that, through the arrangement of the air guide portion, the air entering from the air inlet can be transported from front to back, so as to achieve the effect of heat dissipation of the entire shell.
[0009] Furthermore, an air inlet is provided on both sides of the front end of the bottom cover, and an air guide plate is provided on both sides of the bottom cover. The number and position of the air guide plates can guide the cold air entering the air inlet from the front side of the shell to the middle and rear part of the shell from both sides, thereby enhancing the heat dissipation effect of the whole shell.
[0010] Furthermore, the wind guide plate also includes a wind shielding portion, which is arranged on the side of the wind bearing portion facing away from the wind guide portion, and the two wind shielding portions are located between the two wind guide portions. Its function is to prevent cold air from gathering in the bottom front area of the shell body where the temperature is originally low, thereby improving the utilization rate of cold air and thus improving the overall heat dissipation efficiency.
[0011] Furthermore, the distance between the two air guides is greater than the distance between the left and right ends of the booster pump, and the booster pump is located in the whole formed by the two air guides in a top view of the housing. Its function is to facilitate the flow of cold air around the booster pump and enhance the heat dissipation effect through the design of the spatial relationship between the air guide and the booster pump.
[0012] Furthermore, the top of the air guide plate is lower than the bottom of the booster pump, so that the cool air can move upward along the air guide plate to the booster pump through the height relationship between the top of the air guide plate and the top of the booster pump, and directly cool the booster pump, thereby achieving a good heat dissipation effect.
[0013] Furthermore, the top of the air guide plate is higher than the top of the air inlet, so that the airflow entering the housing through the air inlet can be completely guided by the air guide plate through the height relationship between the top of the air guide plate and the top of the air inlet.
[0014] Furthermore, the front cover plate is provided with a heat dissipation hole, and the height of the heat dissipation hole is set between the air inlet and the air outlet. The position of the heat dissipation hole corresponds to the position of the booster pump. Its function is to directly discharge the heat emitted by the booster pump through the setting of the heat dissipation hole.

[0016] Furthermore, a mounting frame for mounting a cooling fan is provided in the housing, and the exhaust port and the cooling fan are respectively provided on the left and right sides of the housing, and the mounting frame includes a guide plate for guiding the air exhausted by the cooling fan to the exhaust port. Its function is that since it is easy to generate a large noise when the exhaust port is directly arranged corresponding to the cooling fan, the staggered arrangement of the exhaust port and the cooling fan and the arrangement of the guide plate can avoid the exhaust port from generating a large noise, and make the hot air exhausted by the cooling fan blow to the exhaust port along the guide plate.
[0017] The utility model has the beneficial effects:
[0018] 1. Through the design of the positions of the air inlet, the air outlet and the cooling fan, cold air enters the shell from the lower side to dissipate the heat in the space inside the shell. The cold air becomes hot air in the process of dissipating heat for the booster pump. The hot air directly rises to the cooling fan and is blown to the air outlet to be discharged, which can effectively reduce the residual time of the hot air in the shell and achieve good heat dissipation effect. Through the setting of the air guide plate, the cold air can be guided to the middle part of the shell, so that the whole shell can be dissipated, and the overall heat dissipation effect is good.
[0019] 2. By staggering the exhaust vent and the cooling fan and setting the guide plate, it is possible to avoid the exhaust vent from generating loud noise, and to allow the hot air discharged by the cooling fan to blow toward the exhaust vent along the guide plate.

[0028] Example 1
[0029] An oxygen concentrator with an integral heat dissipation duct comprises a housing, such as Figure 4 As shown, a cooling fan 1 and a booster pump 2 are provided in the housing. Figure 1 As shown, the housing includes a top cover 3, a front cover plate 4, and a bottom cover 5 which are arranged in sequence from top to bottom. A heat dissipation fan 1 is arranged near the top cover 3, a booster pump 2 is arranged near the bottom cover 5, an air inlet 6 is arranged on the bottom cover 5, an air outlet 7 is arranged on the upper side of the front cover 4, and an air guide plate 8 for guiding the air entering the housing from the air inlet 6 to the middle of the housing is arranged on the bottom cover 5. Its function is that, through the design of the positions of the air inlet 6, the air outlet 7 and the heat dissipation fan 1, cold air enters the housing from the lower side of the housing to dissipate heat to the space inside the housing, and the cold air becomes hot air in the process of dissipating heat to the booster pump 2. The hot air directly rises to the heat dissipation fan 1 and is blown to the air outlet 7 for discharge, which can effectively reduce the residual time of hot air in the housing and has a good heat dissipation effect; through the arrangement of the air guide plate 8, the cold air can be guided to the middle of the housing, so that the entire housing can be dissipated, and the overall heat dissipation effect is good.
[0030] Specifically, Figure 4As shown, the air inlet 6 is arranged at the front side of the bottom cover 5, and the air guide plate 8 includes an air receiving portion 801 corresponding to the air inlet 6 and an air guide portion 802 for guiding air to the middle of the housing, and the air guide portion 802 is in the shape of a curved surface convex toward the surface where the air inlet 6 is located. The air guide portion 802 is in the shape of a cylindrical surface arranged perpendicularly to the bottom surface of the bottom cover 5. Its function is that, through the arrangement of the air guide portion 802, the air entering from the air inlet 6 can be transported from front to back, so as to achieve the effect of heat dissipation in the housing as a whole.
[0031] Specifically, Figure 2 As shown, an air inlet 6 is respectively provided on the left and right sides of the front end of the bottom cover 5, and an air guide plate 8 is respectively provided on the left and right sides of the bottom cover 5. The function is that the number and position of the air guide plates 8 can transport the cold air entering the air inlet 6 from the front side of the shell to the middle and rear part of the shell from the left and right sides, thereby enhancing the heat dissipation effect of the whole shell.
[0032] Specifically, Figure 4 As shown, the wind guide plate 8 also includes a wind shield 803, which is arranged on the side of the wind receiving portion 801 facing away from the wind guide portion 802, and the two wind shields 803 are located between the two wind guide portions 802. The wind shield 803 is arranged vertically with the front cover plate 4. Its function is that, through the arrangement of the wind shield 803, the cold air can be blocked from gathering in the bottom front area of the shell body where the temperature is originally low, thereby improving the utilization rate of the cold air and thus improving the overall heat dissipation efficiency.
[0033] Specifically, Figure 3 As shown, the distance between the two air guides 802 is greater than the distance between the left and right ends of the booster pump 2. In a top view of the housing, the booster pump 2 is located in the whole formed by the two air guides 802. Its function is to facilitate the flow of cold air around the booster pump 2 and enhance the heat dissipation effect through the design of the spatial relationship between the air guide 802 and the booster pump 2.
[0034] Specifically, Figure 2 As shown, the top height of the air guide plate 8 is lower than the bottom height of the booster pump 2. Its function is that, through the design of the height relationship between the top of the air guide plate 8 and the top of the booster pump 2, the cold air can move upward along the air guide plate 8 to the booster pump 2, directly cool the booster pump 2, and the heat dissipation effect is good.
[0035] Specifically, Figure 2 As shown, the top height of the air guide plate 8 is higher than the top height of the air inlet 6. Its function is that the airflow entering the housing through the air inlet 6 can be completely guided by the air guide plate 8 through the design of the height relationship between the top of the air guide plate 8 and the top of the air inlet 6.
[0036] Specifically, Figure 1As shown, the front cover plate 4 is provided with a heat dissipation hole 9, and the heat dissipation hole 9 is located at a height between the air inlet 6 and the air outlet 7. The location of the heat dissipation hole 9 corresponds to the location of the booster pump 2. Its function is that through the setting of the heat dissipation hole 9, the heat emitted by the booster pump 2 can be directly discharged.
[0037] Specific, combined Figure 1 , Figure 4 As shown, the air outlet 7 and the cooling fan 1 are arranged at the same height.
[0038] Specifically, Figure 4 As shown, a mounting frame 10 for mounting the cooling fan 1 is provided in the housing, and the exhaust port 7 and the cooling fan 1 are respectively arranged on the left and right sides of the housing, the exhaust port 7 is arranged on the left side of the front cover plate 4, and the cooling fan 1 is arranged on the right side of the mounting frame 10, and the mounting frame 10 includes a guide plate 11 for guiding the air exhausted by the cooling fan 1 to the exhaust port 7. The exhaust port 7 is in the shape of a horizontally arranged strip hole. Its function is that since it is easy to generate a large noise when the exhaust port 7 is directly arranged corresponding to the cooling fan 1, the staggered arrangement of the exhaust port 7 and the cooling fan 1 and the arrangement of the guide plate 11 can avoid the exhaust port 7 from generating a large noise, so that the hot air exhausted by the cooling fan 1 is blown to the exhaust port 7 along the guide plate 11.
[0039] The working principle of this embodiment is as follows: cold air enters the housing through the air inlet 6 and is directly blown toward the wind bearing portion 801. A portion of the cold air moves along the wind guide portion 802 to the middle and rear area of the housing, and a portion of the cold air blows toward the wind shield portion 803, is blocked by the wind shield portion 803, and then flows upward. These two portions of cold air rise together around the booster pump 2, and heat can be dissipated from all parts of the booster pump 2, with a good overall heat dissipation effect.
[0040] When the cold air is heated by the booster pump 2 and becomes hot air, it rises rapidly. The hot air rises to the cooling fan 1 and is blown onto the front cover 4 by the cooling fan 1. It is then blown toward the exhaust port 7 along the front cover 4 and the guide plate 11 and discharged, generating less noise.
[0041] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
