Description

Technical Field

[0001] This utility model belongs to the field of oxygen chamber air conditioning technology, specifically relating to an oxygen chamber air conditioning structure with automatic drainage function. Background Technology

[0002] As the core equipment for hyperbaric oxygen therapy, the oxygen chamber needs to maintain a constant temperature and humidity to ensure patient comfort and treatment safety. The air conditioning system is a key component for controlling the oxygen chamber environment. Traditional oxygen chamber air conditioners often use a split design, achieving heat exchange through a surface cooler. Under cooling conditions, a large amount of condensate forms on the surface cooler due to low temperatures. If this condensate is not drained in time, it will breed bacteria, corrode the equipment casing, and may even backflow into the oxygen chamber, causing electrical short circuits or contaminating the chamber, posing a serious safety hazard to the high-pressure, confined environment.

[0003] Existing oxygen chamber air conditioning systems typically employ passive drainage, relying on gravity to naturally drain water through drainage holes at the bottom of the unit. However, when the installation location of the oxygen chamber is limited or the piping is long, it is difficult to ensure a proper drainage slope, easily leading to condensate retention. While some improved solutions add a water collection tray and drainage pipes, they still rely on regular manual inspection and cleaning, creating a regulatory blind spot in continuously operating medical settings. If drainage is inadequate, accumulated water submerging the surface cooler will significantly reduce heat exchange efficiency, while also increasing the fan load, resulting in a decrease in air conditioning cooling capacity and an increase in energy consumption.

[0004] Furthermore, traditional drainage structures lack automated monitoring mechanisms. Mechanical water level control devices, such as float valves, are prone to jamming and failure in the vibration environment of an oxygen chamber. Temperature fluctuations in the circulation pipelines of industrial chillers and surface coolers also accelerate condensation formation. Existing technologies struggle to dynamically respond to water level changes. Therefore, there is an urgent need for an oxygen chamber air conditioning structure with integrated automatic monitoring and timed drainage functions to address these issues. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] This utility model provides an oxygen chamber air conditioning structure with automatic drainage function, including an air conditioning unit, an industrial chiller, and a water receiving tank. The air conditioning unit is connected to the industrial chiller and the water receiving tank. The air conditioning unit includes a shell with an outer cover. A surface cooler is installed inside the shell. A fan, a miniature diaphragm pump, and a time relay are fixed on one side of the outer cover. The fan's outlet passes through the outer cover and directly into the shell to blow airflow into the surface cooler. The miniature diaphragm pump is connected to a drain pipe and a suction pipe. The other end of the suction pipe is connected to the shell, and the other end of the drain pipe is connected to the water receiving tank. The industrial chiller is connected to a first water supply pipe and a second water supply pipe. The industrial chiller is connected to two interfaces on the surface cooler through the first and second water supply pipes. A duckbill float switch is installed on the side wall of the shell. The duckbill float switch is electrically connected to the time relay, and the time relay is electrically connected to the miniature diaphragm pump.

[0008] Furthermore, the housing is provided with a mounting plate for fixing the surface cooler, and protective cotton is bonded to the contact point between the surface cooler and the housing.

[0009] Furthermore, the fan is a DC centrifugal fan.

[0010] Furthermore, an electrical component mounting base is provided on the side of the fan, and the electrical component mounting base is connected to the outer cover of the shell. The miniature diaphragm pump is fixed to the bottom of the electrical component mounting base by a strap, and a time relay is fixedly installed in the electrical component mounting base above the miniature diaphragm pump.

[0014] The beneficial effects of this utility model are:

[0015] Compared with existing technologies, this utility model uses a duckbill-type float switch to detect the water level inside the machine casing in real time, and combines it with a time relay to precisely control the start and stop sequence of the micro diaphragm pump, thereby achieving fully automatic timed discharge of condensate and completely avoiding human intervention and oversight.

Detailed Implementation

[0021] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Combination Figures 1 to 4As shown in the figure, the oxygen chamber air conditioning structure with automatic drainage function provided by this utility model embodiment includes an air conditioning unit, an industrial chiller 15, and a water receiving tank 17. The air conditioning unit is connected to the industrial chiller 15 and the water receiving tank 17 respectively. The air conditioning unit includes a housing 2, with an outer cover 1 attached to the housing 2. A surface cooler 3 is provided inside the housing 2. A fan 4, a miniature diaphragm pump 7, and a time relay 9 are fixedly installed on one side of the outer cover 1. The fan 4 is a DC centrifugal fan. The air outlet of the fan 4 passes through the outer cover 1 and directly enters the interior of the housing 2 to blow airflow into the surface cooler 3 inside the housing 2. A drain pipe 11 and a suction pipe 12 are connected to the miniature diaphragm pump 7 respectively. The other end of the suction pipe 12 is connected to... The drain pipe 11 is connected to the water receiving tank 17 at the other end, which is connected to the housing 2. The industrial chiller 15 is connected to the first water supply pipe 13 and the second water supply pipe 14. The industrial chiller 15 is connected to two interfaces on the surface cooler 3 through the first water supply pipe 13 and the second water supply pipe 14. Both interfaces on the surface cooler 3 are straight-through quick-connect connectors. A duckbill float switch 16 is provided on the side wall of the housing 2. The duckbill float switch 16 is electrically connected to the time relay 9. The time relay 9 is electrically connected to the micro diaphragm pump 7. The duckbill float switch 16 is used to detect the water level of the housing 2 in real time and trigger the time relay 9 to work. The time relay 9 is used to start the micro diaphragm pump 9 to work at a time.

[0023] Specifically, the housing 2 is provided with a mounting plate 5 for fixing the surface cooler 3, and a protective cotton 18 is bonded to the contact point between the surface cooler 3 and the housing 2; the protective cotton 18 can protect the surface cooler 3.

[0024] Specifically, an electrical component mounting base 10 is provided on the side of the fan 4. The electrical component mounting base 10 is connected to the outer cover 1. The miniature diaphragm pump 7 is fixed to the bottom of the electrical component mounting base 10 by a strap 8. A time relay 9 is fixedly installed in the electrical component mounting base 10 above the miniature diaphragm pump 7.

[0025] Specifically, a buffer cotton 6 is provided between the miniature diaphragm pump 7 and the electrical component mounting base 10, which can provide a buffering effect for the miniature diaphragm pump 7.

[0026] Specifically, a temperature and humidity sensor 19 is installed on the lower outer side of the electrical component mounting base 10, corresponding to the position of the miniature diaphragm pump 7, for collecting the temperature and humidity of the working environment of the oxygen chamber air conditioning structure.

[0027] In summary, this invention enhances trigger sensitivity under conditions of minimal water accumulation by using a duckbill-type float switch 16, while the negative pressure suction characteristic of the miniature diaphragm pump 7 thoroughly empties water from dead corners of the cavity, significantly reducing the risk of bacterial growth. The dual shock absorption design of the buffer cotton 6 and protective cotton 18 effectively absorbs the vibrations of the fan 4 and the miniature diaphragm pump 7, preventing malfunction of the duckbill-type float switch 16 and cracking of the weld joints of the surface cooler 3. The application of a DC centrifugal fan and a quick-connect connector optimizes energy efficiency and ease of maintenance, while the temperature and humidity sensor 19 provides data support for monitoring the operating conditions of the oxygen chamber air conditioning system.

[0028] The working principle of this utility model is explained in conjunction with the above-described technical solution and accompanying drawings as follows:

[0029] When the industrial chiller 15 is running in the forward direction, the evaporator inside the industrial chiller 15 absorbs heat to generate chilled water. The chilled water is pumped through the first water supply pipe 13 to the surface cooler 3. On the other side, the fan 4 blows air into the casing 2 and the air flows to the surface cooler 3. The air flows through the fins of the surface cooler 3, and the heat is carried away by the chilled water, thus achieving cooling.

[0030] When the industrial chiller 15 operates in reverse heat pump mode, the condenser inside the industrial chiller 15 releases heat to heat the chilled water, which is then pumped through the second water pipe 14 to the surface cooler 3. On the other side, the fan 4 blows air into the casing 2 and onto the surface cooler 3. The air is heated as it flows through the fins of the surface cooler 3, thus raising the temperature.

[0031] When the water level inside the casing 2 reaches the critical value of the duckbill float switch 16, the time relay 9 is triggered to work. The time relay 9 starts the micro diaphragm pump 7 to work. The micro diaphragm pump transports the condensate inside the casing 2 to the water receiving tank 17 through the water pumping pipe 12 and the drain pipe 11. At the same time, the time relay 9 controls the micro diaphragm pump 7 to drain water at set times according to the set time.

[0032] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
