Description

Technical Field

[0001] This utility model belongs to the field of air purification, specifically relating to a split-type fresh air cabin. Background Technology

[0002] "Fresh air mobile cabin" usually refers to a mobile hospital or mobile isolation point equipped with an advanced fresh air system. It is an upgraded version based on traditional mobile cabin facilities, with a special enhancement of indoor air quality control function.

[0003] In the prior art, modular cabins integrating fresh air systems (such as the CT cabin with a fresh air system disclosed in patent document CN202022752128.7) have been applied in professional fields such as hospitals and laboratories. These cabins typically employ an integrated design that fixes the fresh air equipment to the cabin body. This rigid integration of the fresh air equipment and the cabin body, along with the rigid requirements for equipment installation space and pipeline layout, makes the shape and internal structure of these cabins essentially fixed, making it difficult to flexibly adjust and customize them according to customers' personalized needs for spatial layout, appearance dimensions, or special functions. These integrated fresh air cabins are unsuitable for scenarios with higher requirements for convenience, aesthetics, and environmental integration, such as use as home health spaces, mobile offices, or other civilian health protection facilities (i.e., health cabins); moreover, these integrated fresh air cabins do not possess health and wellness functions. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides a split-type fresh air cabin.

[0005] In this embodiment of the utility model, a split-type fresh air cabin includes a cabin body with a door and an equipment compartment that provides fresh air to the cabin body, which is set independently of the cabin body. The cabin body is assembled from several lightweight, detachable and assembleable cabin panels. The cabin body is provided with a fresh air inlet and an exhaust outlet that communicate with its interior. The equipment compartment includes a cabin shell, and a fresh air conditioning module and an exhaust module installed in the cabin shell. The cabin shell is provided with a fresh air outlet connected to the air outlet of the fresh air conditioning module and an exhaust inlet connected to the air inlet of the exhaust module. The fresh air outlet is directly or indirectly connected to the fresh air inlet, and the exhaust inlet is directly or indirectly connected to the exhaust outlet. The cabin shell is also provided with a main air inlet that communicates with its interior for introducing air and a main air outlet that communicates with its interior for discharging gas.

[0006] Compared with the prior art, the beneficial effects of the superior technical solution of this utility model include:

[0007] 1. Split-type modular design: This utility model adopts a split-type structure, with the equipment compartment independently set outside the main body. This design allows the main body to be flexibly adjusted and customized according to the customer's personalized needs for spatial layout, appearance size, or special functions. Both the main body and the equipment compartment adopt a modular structure, which has the functional characteristics of rapid deployment, mobility and flexibility, and plug-and-play, and can better adapt to application scenarios with higher requirements for convenience, aesthetics and environmental integration.

[0008] 2. Multifunctional Small Independent Space: The cabin of this utility model constitutes an independent, enclosed small space, which is very suitable for temporary or semi-permanent locations, especially in scenarios with high requirements for air quality. It can be flexibly deployed outdoors or indoors to meet various needs, such as: sleep cabin, study / office cabin, fitness cabin, coffee hut, hyperbaric oxygen chamber, etc.

[0009] 3. As a small space, the cabin of this utility model is very suitable for temporary or semi-permanent places and scenarios with high requirements for air quality. It can be installed outdoors or indoors as a sleep cabin, study / office cabin, fitness cabin, coffee hut, hyperbaric oxygen chamber, etc.

[0010] 4. Five-Balance Environment Control and Pressure Management: This invention achieves balanced air quality, temperature, and humidity control within the cabin through independently designed fresh air conditioning and exhaust modules. Temperature regulation can also be achieved using an electric heating film and semiconductor cooling chips. Simultaneously, the cabin's sound insulation and noise reduction capabilities ensure a balanced level of quietness, and an oxygen module maintains a balanced oxygen concentration. This provides a balanced indoor environment of "five balances": cleanliness, temperature, humidity, quietness, and oxygen. Furthermore, the fresh air conditioning module injects fresh air into the cabin, while the exhaust module precisely controls exhaust airflow, enabling micro-positive / micro-negative pressure regulation within the cabin. The exhaust module, working in conjunction with the oxygen module, can also create high-pressure or low-pressure oxygen environments within the cabin.

[0011] 5. Lightweight and Efficient Environmental Control: The cabin of this invention adopts a lightweight, detachable structure and has sound insulation and noise reduction performance. By integrating semiconductor cooling chips, electric heating films, microporous air outlets, and self-exhausting outlets, the cabin itself can provide heating and cooling radiation and active ventilation, significantly improving the autonomy and efficiency of environmental control.

Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] This embodiment provides a split-type fresh air cabin, such as Figure 1 As shown, in a preferred embodiment, the fresh air cabin includes a cabin body 10 with a door 11 and an equipment compartment 20, which is independently set up to provide fresh air to the interior of the cabin body 10. The cabin body 10 and the equipment compartment 20 are either separate or detachably connected as one unit. The cabin body 10 has a rectangular box structure and is assembled from several lightweight (e.g., hollow aluminum alloy) detachable and assembleable (e.g., snap-fit ​​or bolted) cabin panels. The cabin body 10 is provided with a fresh air inlet 10a and an exhaust outlet 10b that communicate with its interior. The fresh air inlet 10a and the exhaust outlet 10b are located on the same side of the cabin body 10. The fresh air inlet 10a is located at the upper part of the cabin body 10 near the top, and the exhaust outlet 10b is located at the lower part of the cabin body 10 near the bottom.

[0016] The equipment compartment 20 includes a housing 21, and a fresh air conditioning module 22 and an exhaust module 23 disposed within the housing 21. The housing 21 is also a rectangular box structure. The housing 21 is provided with a fresh air outlet 21a connected to the air outlet of the fresh air conditioning module 22, and an exhaust inlet 21b connected to the air inlet of the exhaust module 23. The fresh air outlet 21a is directly (aligned connection) or indirectly (connected via pipeline) to the fresh air inlet 10a, and the exhaust inlet 21b is directly connected to the exhaust outlet 10b. The housing 21 is also provided with a main air inlet 21e communicating with its interior for introducing air and a main air outlet 21f communicating with its interior for discharging gas from the housing 21. The fresh air outlet 21a and exhaust air inlet 21b are located on the same side of the cabin 21, near the side where the fresh air inlet 10a is located on the cabin 10. The main inlet 21e and main outlet 21f are located on the same side of the cabin 21, opposite to the fresh air outlet 21a. The fresh air outlet 21a and main inlet 21e are located on the upper part of the cabin 21, near the top of the cabin 21, while the exhaust air inlet 21b and main outlet 21f are located on the lower part of the cabin 21, near the bottom of the cabin 21. It should be noted that for fresh air cabins installed indoors, the main inlet 21e and main outlet 21f can be connected to the outside via ductwork, or they can be placed directly indoors without ductwork. When placed indoors, windows need to be opened.

[0017] According to usage needs, the fresh air cabin is placed in a suitable indoor or outdoor location. Under the action of the fresh air conditioning module 22, outside air enters the cabin shell 21 through the main inlet 21e. The fresh air processed by the fresh air conditioning module 22 is then sent into the cabin 10 through the fresh air inlet 10a. Under the action of the exhaust module 23, the air inside the cabin 10 is discharged through the exhaust outlet 10b and finally exits from the main exhaust outlet 21f. The fresh air conditioning module 22 is used to supply fresh air into the cabin 10, and the exhaust module 23 is used to exhaust stale air from the cabin 10 to form an air circulation and maintain a comfortable environment inside the cabin 10. When the amount of fresh air supplied into the cabin 10 by the fresh air conditioning module 22 is greater than the amount of air exhausted by the exhaust module 23, the cabin 10 is under positive pressure, and the greater the difference, the greater the positive pressure inside the cabin 10. When the exhaust volume is greater than the fresh air volume, the cabin 10 is under negative pressure, and similarly, the greater the difference, the greater the negative pressure inside the cabin 10. It should be noted that when switching modes, the fresh air volume is fixed (generally the minimum fresh air volume required by regulations to maintain indoor hygiene), and the positive and negative pressure environments are created by changing the exhaust volume.

[0018] It should be noted that, Figure 1 This is merely a structural schematic diagram of a split-type fresh air cabin according to this application. The size ratio of the cabin body 10 and the equipment cabin 20 is only for illustrative purposes. In practice, the equipment layout inside the equipment cabin 20 should be as compact as possible to reduce the volume of the equipment cabin 20.

[0019] In this invention, the fresh air conditioning module 22 has a purification and disinfection section, a cooling and heating load section (compressor refrigerant system), and a humidity regulation section to provide clean, temperature-controlled, and humidity-controlled fresh air to the cabin 10. The fresh air conditioning module 22 uses an existing fresh air conditioning unit without an outdoor unit, which is prior art, and its structure and principle will not be described in detail here. Preferably, the exhaust module 23 has a purification and disinfection section, which purifies and disinfects the air inside the cabin 10 before exhausting it, making it more environmentally friendly.

[0020] More preferably, the air inlet of the fresh air conditioning module 22 is located inside the housing 21, and air is drawn in directly from the housing 21. The exhaust outlet (air-cooled heat dissipation outlet) of the fresh air conditioning module 22 is connected to the main exhaust outlet 21f through the exhaust pipe 27. The exhaust air from the exhaust module 23 is introduced into the condenser side of the fresh air conditioning module 22 through the pipe to cool and dissipate heat from the condenser of the fresh air conditioning module 22, and then discharged to the outside of the equipment compartment 20 through the exhaust pipe 27 to achieve heat recovery of the exhaust air.

[0021] In another preferred embodiment, the equipment compartment 20 further includes an oxygen module 24 disposed within the casing 21 for supplying high-pressure or low-pressure oxygen to the compartment 10. The casing 21 has an oxygen outlet 21c connected to the air outlet of the oxygen module 24, and the compartment 10 has an oxygen port 10c communicating with its interior. The oxygen outlet 21c is directly (aligned) or indirectly (connected via pipeline) to the oxygen port 10c. A pressure relief valve 15 is located against the wall near the bottom inside the compartment 10. The oxygen generation module 24 includes an oxygen generator and an air compressor. The oxygen generator provides the oxygen source, and the air compressor provides pressure. Two intake branches are connected in parallel to the inlet of the air compressor, and these two intake branches are respectively connected to the oxygen supply port of the oxygen generator and the atmosphere. Thus, the air compressor can independently deliver compressed air and independently deliver oxygen from the oxygen generator.

[0022] Both the high-pressure oxygen and low-pressure oxygen in the oxygen module 24 supply oxygen to the chamber 10. The difference is that the high-pressure oxygen requires an atmospheric pressure of 1.6 to 3 atmospheres inside the chamber 10, while the low-pressure oxygen requires an atmospheric pressure of 1.1 to 1.3 atmospheres inside the chamber 10. Low-pressure oxygen is suitable for some sub-health care scenarios, while high-pressure oxygen is more suitable for some medical treatment scenarios. When the oxygen supply mode is activated (which users can set via remote control or control panel), users can choose between two scenarios: high-pressure oxygen and low-pressure oxygen. The air compressor of the oxygen generating module 24 can pressurize the cabin 10 to the set atmospheric pressure according to whether the user selects high-pressure or low-pressure oxygen. During the pressurization process, the fresh air conditioning module 22 and the exhaust module 23 are turned off. Once the pressure inside the cabin 10 reaches the set target, during the user's recuperation and health care process, the air compressor of the oxygen generating module 24 continuously injects oxygen. At this time, the exhaust module 23 is turned on to maintain the dynamic balance of the pressure inside the cabin 10 and achieve the effect of ventilation and sewage removal. When the cabin 10 is depressurized, the pressure relief valve 15 inside the cabin 10 is opened to allow the pressure inside the cabin 10 to be quickly restored.

[0023] In another preferred embodiment, the equipment compartment 20 further includes a gas component module 25 for providing functional gases, disposed within the casing 21. The casing 21 has a gas component output port 21d connected to the air outlet of the gas component module 25. The compartment 10 also has a gas component port 10d communicating with its interior. The gas component output port 21d is directly or indirectly connected to the gas component port 10d. According to customer needs, the gas component module 25 introduces health-promoting gases (such as traditional Chinese medicine gases with soothing effects) into the interior environment of the compartment 10 through the gas component port 10d, acting on the user to achieve a soothing and relaxing effect and enhance health protection.

[0024] In another preferred embodiment, the cabin panels of the cabin 10 are made of sound-insulating and noise-reducing materials, such as damping sound-insulating felt / sound-insulating pads, aluminum foam, lightweight sound-insulating boards (such as calcium silicate boards, lightweight reinforced fiber cement boards, oriented strand board combined with sound-insulating coatings / layers, etc., selecting boards with relatively high density but controllable overall weight), polyester fiber sound-absorbing cotton / boards, melamine foam (commonly known as "sound-absorbing cotton" or "pyramid cotton"), honeycomb composite boards, etc. This allows the cabin 10 to not only block external noise and effectively reduce the transmission of external environmental noise into the cabin 10, creating a quiet and private environment, which is especially important for spaces that require rest, focused work, recuperation, or health activities (such as meditation or breathing exercises); it also suppresses internal noise, preventing annoying reverberation and noise accumulation, and improving speech clarity (such as during conference calls or consultations).

[0025] More preferably, the cabin 10 has a light-transmitting window 12, and lighting is installed inside the cabin 10. The lighting adopts a combination of natural light and artificial lighting control. The light-transmitting window 12 can be made of smart photochromic glass, which can switch between electrochromic glass (transmittance adjustable from 10% to 80%) and frosted glass with one button to meet the needs of privacy and natural light.

[0026] In another preferred embodiment, a semiconductor cooling chip 13 is provided in or on the inner surface of some of the compartment panels of the cabin 10, such as at the top of the cabin 10, for radiating heat or cold into the cabin 10. The hot and cold ends of the semiconductor cooling chip 13 can be switched by controlling the current, which is prior art and will not be described in detail here. An electrothermal film 14 is provided in or on the inner surface of some of the compartment panels of the cabin 10, such as at the bottom of the cabin 10, for radiating heat into the cabin 10. This gives the cabin 10 itself the function of radiating heat or cold. In winter, heating is provided by the semiconductor cooling chip 13 and the electrothermal film 14 together, or by either one alone.

[0027] More preferably, the cabin 10 is further provided with a microporous air inlet 10e for self-intake and a self-exhaust outlet 10f for ventilation. The microporous air inlet 10e is located on the top of the cabin 10 (e.g., on the semiconductor cooling chip 13), and the self-exhaust outlet 10f is located on the bottom of the side of the cabin 10. This enables the cabin 10 itself to have ventilation and air exchange functions.

[0028] In another preferred embodiment, oxygen is directly delivered into the cabin 10. The fresh air inlet 10a and the gas component inlet 10d can also be connected to the semiconductor cooling chip 13 through pipes, so that fresh air and health care gas flow downward into the cabin 10 through the microporous air outlet 10e on the semiconductor cooling chip 13. Since there is a pressure gradient inside the cabin 10, fresh air and health care gas will not overflow from the microporous air outlet 10e.

[0029] In another preferred embodiment, the equipment compartment 20 further includes an environmental control module 26 installed outside or inside the housing 21. The enable terminals of the fresh air conditioning module 22, exhaust module 23, oxygen module 24, and gas component module 25 are connected to the output control terminal of the environmental control module 26. The environmental control module 26 controls one or more of the fresh air conditioning module 22, exhaust module 23, oxygen module 24, and gas component module 25 to operate simultaneously. The main function of the environmental control module 26 is to control the operation of each module within the equipment compartment 20 according to different scenario needs, essentially acting as a central control unit. For this fresh air cabin, the environmental control module 26 has a fresh air mode, an oxygen therapy mode, and a health and wellness mode.

[0030] In fresh air mode, the fresh air conditioning module 22 is turned on to input fresh air into the cabin 10, the exhaust module 23 is turned on to exhaust air from the cabin 10, and the oxygen module 24 and the gas component module 25 are turned off. In this mode, the user can further select positive and negative pressure switching. The specific positive and negative pressure creation method is as described above.

[0031] In oxygen therapy mode, oxygen module 24 is activated to provide oxygen and pressure to chamber 10, and exhaust module 23 is activated to exhaust air from chamber 10. In this mode, users can further select high-pressure oxygen and low-pressure oxygen scenarios. During the pressurization phase, oxygen module 24 is activated, while fresh air conditioning module 22, exhaust module 23, and gas component module 25 are deactivated; during the pressure stabilization phase, exhaust module 23 is activated; and during the pressure relief phase, pressure relief valve 27 is activated. The specific methods for creating high-pressure and low-pressure oxygen scenarios are as described above.

[0032] In the health and wellness mode, the gas component module 25 is turned on to provide functional gas to the cabin 10, the fresh air conditioning module 22 is turned on to input fresh air into the cabin 10, the exhaust module 23 is turned on to exhaust air from the cabin 10, and the oxygen module 24 and the gas component module 25 are turned off.

[0033] The three modes mentioned above are independent of each other and cannot be activated simultaneously. The heating and cooling of the cabin 10 are independently controlled by the semiconductor cooling chip 13 and the electric heating film 14.

[0034] In practice, temperature and humidity sensors, air quality sensors (to detect air cleanliness), and oxygen concentration sensors can be installed inside the cabin 10 to monitor the air conditions inside the cabin 10. The modules inside the equipment compartment 20 operate according to the air conditions inside the cabin 10. The specific control principle is the same as the control principle of existing indoor air conditioning, which is existing technology and will not be described in detail here.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
