Description

Technical Field

[0002] At present, the oxygen generators on the market mainly use the principle of pressure swing adsorption technology to produce oxygen. This solution requires the use of a compressor to pressurize the air, and the compressor will generate heat accumulation when it is running. The compressor can only have a normal service life if it is used within the specified temperature range. The increase in ambient temperature will cause the service life of the compressor to decrease.

[0003] In order to solve the heat dissipation problem of the oxygen concentrator compressor, a common solution is to use a cooling fan to blow the compressor body to actively dissipate the heat of the compressor. The utility model patent with the authorization announcement number CN220460286U discloses an oxygen concentrator with a disinfection function, which has a cooling fan installed above the compressor, and the cooling fan sends air to the compressor cylinder for heat dissipation. However, this solution has many corners in the heat dissipation channel and there is no guiding structure for the heat dissipation airflow, which will affect the heat dissipation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] See Figures 1-4, A heat dissipation and air outlet structure of an oxygen generator, including a housing 1, a compressor cover 2, a compressor 3 and a heat dissipation fan 4. The compressor cover 2 is located inside the housing 1. A compressor chamber 5 is formed between the compressor cover 2 and the housing 1. The compressor 3 is located inside the compressor chamber 5. The heat dissipation fan 4 is located at the top of the compressor chamber 5. A heat dissipation air outlet 1.1 is provided at the bottom of the housing 1. An arc-shaped guiding surface 6 is provided at the bottom of the compressor cover 2. The arc-shaped guiding surface 6 is arranged corresponding to the heat dissipation air outlet 1.1. The arc-shaped guiding surface 6 is used to guide the heat dissipation air flow towards the heat dissipation air outlet 1.1. The heat dissipation fan 4 blows air into the compressor chamber 5 from above to form a heat dissipation air flow. The heat dissipation air flow flows from top to bottom to take away the heat of the compressor 3. The heat dissipation air flow is guided by the arc-shaped guiding surface 6 to a substantially horizontal flow direction and then discharged to the outside of the oxygen generator from the heat dissipation air outlet 1.1.

[0022] In a preferred embodiment, a guiding plate 7 is provided on the arc-shaped guiding surface 6. The guiding plate 7 is vertically arranged and the end of the guiding plate 7 faces the heat dissipation air outlet 1.1. A plurality of guiding plates 7 are arranged in parallel at intervals. The heat dissipation air flow blown down from above forms a more turbulent air flow with a higher temperature after passing through the compressor 4 and the arc-shaped guiding surface 6. Turbulence will reduce the efficiency of the air flow discharged from the heat dissipation air outlet 1.1. The guiding plate 7 can guide the turbulence into an air flow aligned with the direction of the heat dissipation air outlet 1.1, reducing the length of the air flow turbulence and being beneficial to improving the heat dissipation efficiency.

[0023] Preferably, the arc-shaped guiding surface 6, the guiding plate 7 and the compressor cover 2 are integrally formed, which is beneficial to reducing the number of components and facilitating the rapid assembly of the oxygen generator.

[0024] Furthermore, an anion generator 8 is also provided inside the oxygen generator. The anion generating head 8.1 of the anion generator 8 is located between the arc-shaped guiding surface 6 and the heat dissipation air outlet 1.1. The anion generator 8 can be mounted on the compressor cover 2. The anion generating head 8.1 of the anion generator 8 penetrates from outside the compressor chamber 5 into the inside of the compressor chamber 5. The anion generating head 8.1 can pass through the arc-shaped guiding surface 5 and be fixed. The anion generating head 8.1 carries static charges, which can increase the content of negative oxygen ions in the air and improve the air quality within a certain range. Installing the anion generating head 8.1 between the arc-shaped guiding surface 6 and the heat dissipation air outlet 1.1 is beneficial to timely taking away the dust adsorbed by the anion generating head 51 through the heat dissipation air flow and improving the service life of the anion generator 5.

[0025] Among them, the housing 1 includes a front housing 1.2 and a rear housing 1.3. The compressor chamber 5 is located between the compressor cover 2 and the rear housing 1.3, and the heat dissipation air outlet 1.1 is located at the bottom of the rear housing 1.3. When the oxygen generator is in use, the housing can include a front housing 1.2, a rear housing 1.3, a left housing (not shown), a right housing (not shown), a top housing (not shown), and a bottom housing (not shown). These housings are not independent of each other. In most cases, the left and right housings and / or the front and rear housings are integrally formed with the front housing 1.2 or the rear housing 1.3. The front housing 1.2 and the rear housing 1.3 in this embodiment only refer to the housings on the front and rear sides of the oxygen generator, excluding the top housing and the bottom housing. The heat dissipation air outlet 1.1 is usually formed by a hollow structure or a grille structure. The heat dissipation air outlet 1.1 is provided at the bottom of the rear housing 1.3, so that the hollow structure or the grille structure of the heat dissipation air outlet 1.1 is distributed substantially in a vertical plane. The arc-shaped guide surface 6 and the guide plate 7 guide the heat dissipation air to be substantially in a horizontal direction toward the heat dissipation air outlet 1.1, which is beneficial to discharging the heat dissipation air from the heat dissipation air outlet 1.1 of the oxygen generator as much as possible.

[0026] In order to simplify the installation and disassembly of the heat dissipation fan 4, a fan bearing plate 1.3.1 is provided on the rear housing 1.3. A part of the heat dissipation fan 4 is supported on the fan bearing plate 1.3.1, and a part of the heat dissipation fan 4 is supported on the top of the compressor cover 2. Preferably, a left limiting plate 1.3.2 and a right limiting plate 1.3.3 are further provided on the rear housing 1.3, and the heat dissipation fan 4 is positioned by the left limiting plate 1.3.2 and the right limiting plate 1.3.3. A buckle structure 2.1 is further provided on the top of the compressor cover 2, and the base of the heat dissipation fan 4 is snapped into the buckle structure 2.1. With such an installation structure of the heat dissipation fan 4, when installing the heat dissipation fan 4, it only needs to be clamped and positioned between the rear housing 1.3 and the compressor cover 2.
