Description

Technical Field

[0001] The present invention relates to the technical field of shelter hospital systems, and in particular to a fresh air device. The present invention also relates to an emergency surgery shelter comprising the fresh air device. Background Art

[0002] The Fangcang shelter hospital system is a modular, rapidly deployable temporary medical facility, mainly used to respond to public health emergencies such as infectious disease outbreaks, natural disasters and other emergencies. The design concept of Fangcang shelter hospitals is to quickly build temporary hospitals through standardized, modular components to expand medical capacity and respond to large-scale patient needs.

[0003] Emergency surgery shelters are an important part of the shelter hospital system. They are usually equipped with life support equipment such as operating tables, anesthesia machines, ECG monitors, and ventilators, enabling shelter hospitals to perform emergency operations on patients. In order to meet the needs of a sterile surgical environment, emergency surgery shelters are usually equipped with fresh air equipment. However, compared with conventional hospitals, the deployment environment of shelter hospitals is complex and the conditions are relatively harsh. After being used in harsh environments for a period of time, conventional fresh air equipment will become clogged and contaminated in the filter elements, resulting in a decrease in filtering capacity. Emergency surgery shelters that use conventional fresh air equipment have certain problems in environmental adaptability.

[0004] It can be seen from the above existing technologies that emergency surgery cabins that use conventional fresh air equipment have defects in environmental adaptability because they cannot maintain filtering capabilities in harsh environments or after long-term use. Summary of the invention

[0005] In view of this, the present invention aims to propose a fresh air device that can provide clean air for the emergency operating room and can perform self-cleaning. The filtering effect will not be affected by harsh environment or long-term use. It has the advantages of strong environmental adaptability and easy operation.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A fresh air device comprises a mounting frame, which is arranged in a direction vertical to the ground;

[0008] A driving assembly, arranged on one side of the installation frame;

[0009] A self-cleaning component is arranged below the installation frame;

[0010] A filter screen, one end of which is located in the mounting frame and the other end of which is located in the self-cleaning assembly;

[0011] The filter is located at both ends of the installation frame and the self-cleaning component and can be switched under the action of the driving component:

[0012] Further, the self-cleaning assembly includes a cleaning box, which is arranged below the mounting frame;

[0013] A water inlet pipe, one end of which is connected to the cleaning box;

[0014] A drainage pipe, disposed at the bottom of the cleaning box and connected to the interior of the cleaning box;

[0015] The driven shaft is rotatably arranged inside the cleaning box.

[0016] Furthermore, the self-cleaning component also includes a one-way valve, which is arranged on the water inlet pipe to make the water inlet pipe unidirectional along the direction of entering the cleaning box.

[0017] Furthermore, one end of the water inlet pipe away from the cleaning box is passed through the installation frame and extends in a winding manner inside the installation frame;

[0018] The water inlet pipe is located at one end of the inner side of the cleaning box at a middle position in the thickness direction of the cleaning box.

[0019] Furthermore, two parallel slits are provided on the top of the cleaning box to allow a single layer of the filter to pass through;

[0020] A rubber ring is arranged at the edge of the slit.

[0021] Further, the driving assembly includes a driving motor, which is detachably arranged on one side of the mounting frame;

[0022] A drive shaft, one end of which is connected to the power output shaft of the drive motor and is rotatably disposed inside the mounting frame;

[0023] The filter screen is configured to be made of a flexible material and is in a cylindrical shape sleeved on the driving shaft and the driven shaft.

[0024] Furthermore, the driving motor is a bidirectional servo motor.

[0025] Furthermore, a dust cover is provided on the top of the installation frame;

[0026] The dust cover extends from the top of the installation frame to the bottom of the driving shaft, forming a shield for the gap between the driving shaft and the installation frame.

[0027] The fresh air device in the present invention has an installation frame that can, on the one hand, provide position limiting and support for the installation of the drive component, the self-cleaning component and the filter, and fix its relative position with other parts of the structure; on the other hand, it can fix itself at the ventilation window on the side wall of the emergency surgery cabin to achieve filtering. One end of the filter is installed in the installation frame, which plays a role in filtering and removing impurities, and the other end is installed in the self-cleaning component. The self-cleaning component can clean and remove impurities from one end of the filter located in the self-cleaning component. The drive component can drive the two ends of the filter to switch between the installation frame and the self-cleaning component, so that the part of the installation frame that is contaminated and blocked by impurities can enter the self-cleaning component, and at the same time, the cleaned part of the self-cleaning component enters the installation frame, thereby realizing the automatic cleaning function of the fresh air device, and the filtering effect will not be affected by harsh environment or long-term use, and it has the advantages of strong environmental adaptability and easy operation.

[0028] Secondly, by setting the self-cleaning component as a structure of a water tank, a water inlet pipe, a drain pipe and a driven shaft, the cleaning tank can be used as a container for flushing and cleaning the filter, and it also plays a role in temporarily storing the cleaning water. The water inlet pipe can serve as a channel for the purified high-temperature purified water to enter the cleaning tank, and the drain pipe can discharge the sewage and impurities in the cleaning tank to the outside. The driven shaft rotating in the cleaning tank plays a supporting role for the filter.

[0029] By arranging a one-way valve on the water inlet pipe, the water flow in the water inlet pipe can only be directed in one direction toward the cleaning box, thus avoiding pollution caused by the backflow of sewage in the cleaning box.

[0030] By inserting the end of the water inlet pipe away from the cleaning box through the installation frame, and arranging the part of the water inlet pipe located inside the installation frame in a winding and extending manner, when high-temperature purified water is introduced into the water inlet pipe, the part of the filter located inside the installation frame can be heated and dried, thereby accelerating the drying speed of the filter. By arranging the end of the water inlet pipe located inside the cleaning box in the middle of the thickness direction of the cleaning box, the water outlet of the water inlet pipe is located between the two sides of the filter, and the water flow direction makes it easier to flush away impurities blocked on the surface of the filter.

[0031] By setting a slit structure on the top of the cleaning box that allows a single layer of the filter to pass through, the cleaning box can remove impurities blocked on the filter or adhering sewage by scraping; by bonding a rubber ring on the edge of the slit structure, the scraping and impurity removal effect can be further improved, thereby achieving the purpose of improving the cleaning ability of the self-cleaning component.

[0032] Thirdly, by configuring the drive assembly to be a structure of a drive motor and a drive shaft, the drive motor can drive the drive shaft to rotate around its own axis, and the filter screen mounted on the drive shaft and the driven shaft can rotate under the drive shaft, thereby switching between the end located inside the installation frame and the end located inside the self-cleaning assembly. By configuring the drive motor to be a bidirectional servo motor, the filter screen can move forward or backward under the drive shaft, thereby adapting to different working conditions.

[0033] In addition, by providing a dust cover on the top of the mounting frame, a shield can be formed in the gap between the drive shaft and the mounting frame, which helps to prevent dust and impurities from entering the interior of the emergency surgery cabin through the gap.

[0034] The present invention also includes an emergency surgery cabin, which adopts the fresh air device as described above.

[0035] The technical effect that can be achieved by the fresh air device in the present invention in the emergency operating room is the same as the technical effect that can be achieved by the fresh air device compared with the prior art, and will not be described again here.

[0048] Embodiment 1

[0049] This embodiment relates to a fresh air device that can be installed on the side wall of an emergency surgery cabin to filter and remove impurities from the air entering and exiting the window. By setting a drive component and a self-cleaning component, the filter can cyclically change its relative position with the installation frame and the self-cleaning component under the action of the drive component, and the self-cleaning component can clean the filter. By combining the above structure, clean air can be provided for the emergency surgery cabin, and it can be self-cleaning. The filtering effect will not be affected by harsh environment or long-term use, and it has the advantages of strong environmental adaptability and easy operation.

[0050] In terms of overall structure, refer to Figure 1 and Figure 2 The fresh air device of this embodiment includes an installation frame 1, a drive assembly 2, a self-cleaning assembly 3 and a filter 4. The installation frame 1 is arranged in a direction perpendicular to the ground. The drive assembly 2 is installed on one side of the installation frame 1. The self-cleaning assembly 3 is arranged below the installation frame 1. One end of the filter 4 is located in the installation frame 1, and the other end is located in the self-cleaning assembly 3. The two ends of the filter 4 respectively located in the installation frame 1 and the cleaning assembly can be switched under the action of the drive assembly 2.

[0051] On the one hand, the installation frame 1 can provide limit and support for the installation of the drive component 2, the self-cleaning component 3 and the filter 4, and fix its relative position with other parts of the structure. On the other hand, it can fix itself at the ventilation window on the side wall of the emergency surgery cabin to achieve filtering. One end of the filter 4 is installed in the installation frame 1, which plays a role in filtering and removing impurities, and the other end is installed in the self-cleaning component 3. The self-cleaning component 3 can clean and remove impurities from one end of the filter 4 located in the self-cleaning component 3. The drive component 2 can drive the two ends of the filter 4 to switch between the installation frame 1 and the self-cleaning component 3, so that the part of the installation frame 1 that is contaminated and blocked by impurities can enter the self-cleaning component 3, and at the same time, the cleaned part of the self-cleaning component 3 enters the installation frame 1, thereby realizing the automatic cleaning function of the fresh air device, and the filtering effect will not be affected by the harsh environment or long-term use, and it has the advantages of strong environmental adaptability and easy operation.

[0052] Reference Figure 1 and Figure 2 In order to clean the filter screen 4, in this embodiment, the self-cleaning component 3 includes a cleaning box 301, a water inlet pipe 302, a drain pipe 303 and a driven shaft 304. Among them, the cleaning box 301 is arranged vertically to the ground and is located below the installation frame 1. The cleaning box 301 is a hollow box. One end of the water inlet pipe 302 is connected to the inside of the cleaning box 301, and the other end is connected to the pressurized purified water. The drain pipe 303 is installed at the bottom of the cleaning box 301, and the two ends of the drain pipe 303 are respectively connected to the inside of the cleaning box 301 and the outside. The driven shaft 304 is rotatably arranged inside the cleaning box 301.

[0053] By configuring the self-cleaning component 3 to be a structure of a water tank, a water inlet pipe 302, a drain pipe 303, and a driven shaft 304, the cleaning box 301 can be used as a container for flushing and cleaning the filter 4, and can also temporarily store the cleaning water. The water inlet pipe 302 can be used as a channel for purified high-temperature purified water to enter the cleaning box 301, and the drain pipe 303 can discharge the sewage and impurities in the cleaning box 301 to the outside. The driven shaft 304 rotatably arranged in the cleaning box 301 supports the filter 4.

[0054] Reference Figure 1 and Figure 2 In this embodiment, in order to prevent the sewage in the cleaning box 301 from flowing back and causing pollution, the self-cleaning component 3 also includes a one-way valve 305 installed on the water inlet pipe 302.

[0055] By arranging a one-way valve 305 on the water inlet pipe 302 , the water flow in the water inlet pipe 302 can only flow in a one-way direction toward the cleaning box 301 , thereby avoiding pollution caused by the backflow of sewage in the cleaning box 301 .

[0056] Reference Figure 1 and Figure 2 In this embodiment, for the purpose of further improving the cleaning ability of the self-cleaning assembly 3, one end of the water inlet pipe 302 away from the cleaning box 301 is passed through the installation frame 1, and the part of the water inlet pipe 302 located inside the installation frame 1 is coiled and extended. The end of the water inlet pipe 302 located inside the cleaning box 301 is set in the middle position of the cleaning box 301 in the thickness direction.

[0057] By inserting the end of the water inlet pipe 302 away from the cleaning box 301 on the installation frame 1, and arranging the portion of the water inlet pipe 302 located inside the installation frame 1 in a winding and extending manner, when high-temperature purified water is introduced into the water inlet pipe 302, the portion of the filter screen 4 located inside the installation frame 1 can be heated and dried, thereby accelerating the drying speed of the filter screen 4. By arranging the end of the water inlet pipe 302 located inside the cleaning box 301 in the middle position in the thickness direction of the cleaning box 301, the water outlet of the water inlet pipe 302 is located between the two sides of the filter screen 4, and the water flow direction makes it easier to flush away impurities blocked on the surface of the filter screen 4.

[0058] Reference Figure 1 and Figure 2 In this embodiment, in order to further improve the cleaning ability of the self-cleaning assembly 3, two parallel slits are opened on the top of the cleaning box 301. The slits allow a single row of filter screens 4 to pass through. The edges of the slits are installed with rubber rings by means of structural adhesive bonding.

[0059] By setting a slit structure that allows a single layer of the filter 4 to pass through on the top of the cleaning box 301, the cleaning box 301 can remove impurities or sewage stuck on the filter 4 by scraping; by bonding a rubber ring on the edge of the slit structure, the scraping and impurity removal effect can be further improved, thereby achieving the purpose of improving the cleaning ability of the self-cleaning component 3.

[0060] Reference Figure 1 and Figure 3 In this embodiment, for the purpose of driving the filter screen 4 to move, the driving assembly 2 includes a driving motor 201 and a driving shaft 202. One end of the driving shaft 202 is connected to the power output shaft of the driving motor 201 through a coupling. The driving shaft 202 is rotatably arranged on the inner side of the mounting frame 1. The filter screen 4 is configured to be cylindrical and sleeved on the driving shaft 202 and the driven shaft 304. The driving motor 201 is configured to be a bidirectional servo motor.

[0061] By configuring the drive assembly 2 to include a drive motor 201 and a drive shaft 202, the drive motor 201 can drive the drive shaft 202 to rotate around its own axis, and the filter screen 4 sleeved on the drive shaft 202 and the driven shaft 304 can rotate under the drive of the drive shaft 202, thereby realizing the position switching between the inner end of the installation frame 1 and the inner end of the self-cleaning assembly 3. By configuring the drive motor 201 to be a bidirectional servo motor, the filter screen 4 can move forward or backward under the drive of the drive shaft 202, thereby adapting to different working conditions.

[0062] Reference Figure 1 In this embodiment, in order to further improve the purification capacity of the fresh air device, a dust cover 5 is provided on the top of the installation frame 1. The dust cover 5 extends downward from the top of the installation frame 1 to the bottom of the paper drive shaft 202, forming a shield for the gap between the drive shaft 202 and the installation frame 1.

[0063] By providing a dust cover 5 on the top of the installation frame 1, a shield can be formed in the gap between the drive shaft 202 and the installation frame 1, which is helpful to prevent dust and impurities from entering the interior of the emergency surgery cabin through the gap.
