Description

Technical Field

[0001] The utility model relates to the technical field of space suits, in particular to a portable ventilation device. Background Art

[0002] The airtightness of the space suit is extremely good. Therefore, when the astronauts put on the space suit, if they do not connect the ventilation equipment to circulate the air inside and outside the space suit, the body heat and breath steam generated by the normal metabolism of the astronauts cannot be discharged outside the space suit. In this case, the astronauts will sweat a lot in a short period of time and feel very uncomfortable. Therefore, portable ventilators are necessary equipment for astronauts to circulate the air inside and outside the space suit.

[0003] For example, Xi Linbin et al. proposed a portable ventilation and heat regulation scheme in "Development of a portable space suit ventilation and heat regulation device." Aerospace Medicine and Medical Engineering 21.3 (2008): 4. When astronauts are on the ground, they need to carry a portable space suit ventilation and heat regulation device, which is connected to the space suit to regulate the heat dissipation of the space suit. However, the portable regulation device will restrict the astronauts' activities during actual use and has poor flexibility.

[0004] Patent application CN103224038A also discloses a two-wheel energy recovery system for an extravehicular space suit life support system. In this device, high-pressure oxygen is used to drive the turbine to rotate and drive the fan to work, so as to realize the circulation of gas in the space suit. However, the normal operation of the device depends on the supply of high-pressure oxygen from the life support system of the space suit itself, and it cannot independently realize the circulation of air in the space suit. Moreover, this ventilation device still needs to be carried by hand, so it will still restrict the activities of astronauts.

[0005] Therefore, there is an urgent need for a more portable space suit ventilation device. Summary of the invention

[0006] The purpose of the utility model is to provide a portable ventilation device, which partially solves or alleviates the above-mentioned deficiencies in the prior art and can provide a wearable ventilation device with limited height.

[0007] In order to solve the above-mentioned technical problems, the utility model specifically adopts the following technical solutions: a portable ventilation device, comprising:

[0008] A main body, the shell of the main body comprises: a first support plate, a second support plate, and a first connecting plate and a second connecting plate for connecting the first support plate and the second support plate; wherein the two ends of the first support plate and the second support plate are sequentially provided with a support area, a transition area and a fitting area; wherein, when the ventilation device is worn on a protective suit, the support area corresponds to the back area of ​​the protective suit, the fitting area corresponds to the waist side of the protective suit, and the heights of the support area, the transition area and the fitting area decrease sequentially; and at least one vent is provided on the shell;

[0010] A first connector is provided at one of the fitting areas of the main body, and a second connector matched with the first connector is provided at another fitting area, and the main body is worn on the protective clothing through the cooperation of the first connector and the second connector.

[0013] In some embodiments, the protective suit is a space suit.

[0014] In some embodiments, an external ventilation duct is also connected to the outside of the main body, the air inlet of the external ventilation duct is arranged in the transition zone and connected to the main ventilation duct, and the air outlet of the external ventilation duct is connected to the protective clothing, so that when the target object wears the protective clothing and the ventilation device, the air outlet of the external ventilation duct is located at the connection between the buttocks and the outer thigh of the target object.

[0015] In some embodiments, a flow sensor and / or a pressure sensor is provided on the main ventilation duct or the external ventilation duct.

[0016] In some embodiments, the first connecting member or the second connecting member includes: a retractable connecting belt, one end of which is fixedly connected to the main body, and the other side of the connecting belt is provided with a quick-release structure.

[0021] Multiple battery units are arranged on both sides of the waist, and multiple independent integrated fans are arranged in the middle (i.e. the support area), thus forming a regionally concentrated and overall dispersed layout. This regionally concentrated and overall dispersed layout can further coordinate the key distribution of multiple units and ensure a sense of balance during wearing.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Herein, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0036] In this document, the terms "upper", "lower", "inner", "outer", "front", "rear", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In this document, unless otherwise clearly specified or limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0038] Herein "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] Herein, "plurality" means two or more than two, ie, it includes two, three, four, five, etc.

[0040] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0041] As used in this specification, the term "about" typically means + / - 5% of the stated value, more typically + / - 4% of the stated value, more typically + / - 3% of the stated value, more typically + / - 2% of the stated value, even more typically + / - 1% of the stated value, and even more typically + / - 0.5% of the stated value.

[0042] In this specification, some embodiments may be disclosed in a format of being in a range. It should be understood that this description of "being in a range" is only for convenience and brevity, and should not be interpreted as a rigid limitation on the disclosed range. Therefore, the description of the range should be considered to have specifically disclosed all possible sub-ranges and independent numerical values ​​within this range. For example, the description of the range 1-6 should be considered to have specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., as well as individual numbers within this range, such as 1, 2, 3, 4, 5 and 6. Regardless of the breadth of the range, the above rules apply.

[0043] Herein, "blower" refers to a machine that increases gas pressure and discharges gas by inputting mechanical energy. For example, in some embodiments, the blower may be a turbine blower, which includes a turbine motor and turbine blades.

[0044] When astronauts work on the ground wearing space suits, the moisture (such as sweat) and heat generated by the astronauts cannot be dissipated in time, which will cause the temperature and humidity inside the space suit to increase, thereby increasing the discomfort of the astronauts. At present, in order to alleviate the problem of heat and moisture being difficult to dissipate, an external ventilation device is required (for example, the ventilation device can be a portable box connected to the space suit through a pipe), which is very inconvenient to operate.

[0045] In this regard, the present application proposes an integrated fan module and a corresponding multi-stage dynamic adjustment method, so that the integrated fan design and the multi-stage dynamic adjustment can be coordinated to achieve adaptive wind force adjustment more accurately and efficiently. At the same time, this multi-independent fan design matched with dynamic adjustment can effectively save energy and control the space occupied by the fan module, so that the fan module can be directly worn on the space suit without causing excessive interference to the astronauts' activities.

[0046] Embodiment 1

[0047] like Figure 1 As shown, the present application provides a ventilation device control system, comprising:

[0048] An activity parameter acquisition module 11 is configured to acquire at least one activity parameter of a target object, wherein the target object wears protective equipment, and a fan module is provided on the protective equipment, and the fan module is configured to transport a fluid into the protective equipment;

[0049] For example, the fan module can be integrated with a battery and a belt to form a ventilation device, and the target object can wear the ventilation device during activities to facilitate real-time wind speed adjustment.

[0050] The activity trend prediction module 12 is configured to classify the activity trend of the target object according to the size of the activity parameter to obtain the activity trend level of the target object at the first time; the activity trend level includes: level one and level two;

[0051] In some embodiments, the activity parameters include: body posture data (e.g., joint rotation angle, motion displacement, etc.) of the target object (e.g., astronaut) collected by at least one sensor. The body posture data can be used to reflect the activity trend of the target object in the future.

[0052] The internal environment acquisition module 13 is configured to acquire at least one internal environment parameter of the protective equipment and calculate the internal environment difference between at least one internal environment parameter and a preset target parameter; wherein at least one internal environment parameter includes one or more of the following: temperature, humidity;

[0053] Among them, temperature or humidity can be used to reflect the physical effect of the target object at the current moment.

[0054] The internal environment determination module 14 is configured to classify the current internal environment of the protection device according to the size of the internal environment difference to obtain a current adjustment level of the current internal environment, and the current adjustment level includes: level one and level two;

[0055] The fan control level determination module 15 is configured to determine the control level of the fan module according to the activity trend level and the current environment adjustment level using a preset first rule; wherein the first rule includes: when the activity trend level and the current environment adjustment level are both level one, the control level belongs to the first control interval; when the activity trend level and the current environment adjustment level are both level two, the control level belongs to the third control interval; when the activity trend level is level one and the current environment adjustment level is level two, or when the activity trend level is level two and the current environment adjustment level is level one, the control level belongs to the second control interval.

[0056] Different from the temperature control scheme based on multi-dimensional factors adopted by traditional protective clothing, this embodiment only selects limited dimensions such as activity parameters and internal environmental parameters to quickly evaluate the control level of the fan module (such as wind force). Among them, activity parameters and internal environmental parameters can respectively rate the control level efficiently and accurately from two aspects: activity trend prediction in the future period and somatosensory data at the current moment.

[0057] Moreover, this multi-level dynamic adjustment based on limited dimensions can not only effectively combine the astronauts' activity characteristics to make comprehensive decisions, but the collection of limited data can also reduce the pressure of data collection and data transmission to a certain extent, and thus can also control the application cost of the control system, that is, control the research and development cost of the space suit.

[0058] In some embodiments, it also includes:

[0059] The external environment acquisition module 16 is configured to acquire at least one external environment parameter of the protective equipment, wherein the external environment parameter includes one or more of the following: temperature and humidity;

[0060] The correction mode evaluation module 17 is configured to determine the correction mode corresponding to the external environment parameter by adopting a second rule; wherein the second rule includes: when the external environment parameter belongs to a preset first external threshold range, the correction mode is to decrease (for example, the corrected control level L (corrected result) = L1 (original level) - L3 (corrected level), L3 can be freely set by the user); when the external environment parameter belongs to a preset second external threshold range, the correction mode is to maintain;

[0061] In some embodiments, the second rule further includes: when the external environment parameter belongs to a preset third external threshold range, the correction mode is to increase (for example, the corrected control level L (corrected result) = L1 (original level) + L2 (corrected level), and L2 can be freely set by the user). The first external threshold range is smaller than the second external threshold range, and the second external threshold range is smaller than the third external threshold range.

[0062] For example, in some embodiments, when the external ambient temperature (or humidity) is relatively high, the wind force is appropriately increased; when the external ambient temperature (or humidity) is relatively low, the wind force is appropriately reduced to save electricity.

[0063] The correction module 18 is configured to correct the control level in the wind turbine control level determination module by adopting the correction mode to obtain a new control level.

[0064] In this embodiment, in order to further control the weight and volume of the fan module and optimize the adjustment effect, limited external environmental parameters can also be used to assist in correcting the control level. This control level obtained by comprehensive correction based on limited dimensions such as future trend prediction, somatosensory environment judgment, and external environment judgment can more sensitively respond to real-time scenes to adjust wind force, so as to save electricity while meeting the somatosensory comfort. Among them, power saving can further reduce the necessary battery volume and battery mass, and the monitoring of limited parameters can also reduce the setting of necessary monitoring systems, thereby reducing the burden on astronauts.

[0065] Furthermore, in some embodiments, in order to simplify the control system, a power monitoring module 24 may be provided. For example, when the power level of the battery is monitored to be within the first power range, the activity trend level and the current internal environment adjustment level are used for judgment, and when the power level of the battery is monitored to be within the second power range, the control level is further modified using external environmental parameters to optimize the remaining power consumption decision.

[0066] The second power range is smaller than the first power range. For example, the first power range is [a, b], the second power range is [c, d], and d is smaller than or equal to a.

[0067] In some embodiments, the activity parameter acquisition module 11 includes:

[0068] The first parameter acquisition unit 11a is configured to acquire a first activity parameter of the upper torso of the target object using at least one sensor,

[0069] The second parameter acquisition unit 11b is configured to acquire a second activity parameter of the lower trunk of the target object using at least one sensor; wherein the activity parameter includes at least one of the following: a muscle surface signal, a motion displacement.

[0070] In some embodiments, the sensor may be disposed on the protective device to directly collect movement changes of the protective device, or the sensor may be disposed on a body part of the target object.

[0071] For example, in some embodiments, the first activity parameter may be the movement displacement of the upper limb (such as the joint angle rotation data of the upper limb).

[0072] For another example, in some embodiments, the first activity parameter may also be the muscle surface pressure of the upper torso (such as the arms and back), or the electromyographic signal on the skin surface.

[0073] Furthermore, in order to improve the adjustment efficiency while ensuring the effectiveness of the adjustment mode, in this embodiment, four typical activity modes are preferably set for astronauts' ground activities: static mode (when the astronauts' posture changes slightly), in-situ activity mode (when the astronauts may perform some simple movements in situ), slow walking mode (for example, moving forward at a first set speed), and fast walking mode (for example, moving forward at a second set speed (greater than the first set speed), and fast walking may even include running, etc.).

[0074] For example, in some embodiments, the activity trend level is correspondingly divided from small to large into level one (such as static mode), level two (such as in-place activity mode), level three (such as slow walking mode), and level four (such as fast walking mode). Among them, when the first activity parameter belongs to the first activity range B1 and the second activity parameter belongs to the second activity range B2, the activity trend level is level one; when the first activity parameter belongs to the third activity range B3 and the second activity parameter belongs to the fourth activity range B4, the activity trend level is level two; when the second activity parameter belongs to the fifth activity range B5, the activity trend level is level three; when the second activity parameter belongs to the sixth activity range B6, the activity trend level is level four.

[0075] Further, in some embodiments, when the activity trend level is level three and the current environment adjustment level is level one, the control level belongs to the second control interval; when the activity trend level is level three and the current environment adjustment level is level two, the control level belongs to the fourth control interval; when the activity trend level is level four and the current environment adjustment level is level one, the control level belongs to the fourth control interval; when the activity trend level is level four and the current environment adjustment level is level two, the control level belongs to the fifth control interval.

[0076] In some embodiments, the fan module 19 includes: at least two independent fan units, the fan unit includes: a fan, and a baffle used to be sleeved on the outer periphery of the fan, an activity space (or a first space) is formed inside the baffle, and the baffle is connected to a sub-ventilation duct; at least two of the sub-ventilation ducts are connected to a main ventilation duct, and the main ventilation duct is used to input the fluid into the protective device;

[0077] Wherein, when the fan is in working state, the baffle guides the drainage effect generated by the fan to be concentrated inside the activity space, and is collected to the main ventilation duct through the sub-ventilation duct.

[0078] Correspondingly, in some embodiments, the control level is also associated with wind turbine information, and the wind turbine information includes: a wind turbine ID (such as a wind turbine number), and a corresponding wind turbine wind force level.

[0079] In this embodiment, a multi-unit independent fan design is used in coordination with a multi-stage dynamic adjustment system, which can more flexibly achieve multi-stage adjustment of wind power to reduce the adjustment pressure of a single fan.

[0080] For example, when the control level is relatively small, only some fans may be enabled, and when the control level is relatively high, all fans may be started.

[0081] In some embodiments, a flow sensor is provided on the main ventilation duct, and further comprises:

[0082] The first flow monitoring module 20 is configured to obtain a first actual flow of the main ventilation duct; and determine whether the first actual flow is consistent with the target flow corresponding to the control level, and if not, enter the actual pressure monitoring module;

[0083] The actual pressure monitoring module 21 is configured to obtain the actual pressure of the main ventilation duct when the first actual flow rate is less than the target flow rate;

[0084] The pressure assessment module 22 is configured to send a first recommended maintenance signal to prompt priority maintenance of the ventilation duct (such as the main ventilation duct) when the actual pressure is greater than the target pressure corresponding to the control level; and to send a second recommended maintenance signal to prompt priority maintenance of the fan module when the actual pressure falls within the target pressure.

[0085] In some embodiments, a flow sensor is also provided on the sub-ventilation duct, and when the second recommended maintenance signal is detected, the flow inside the sub-ventilation duct can be further monitored. For example, the system further includes:

[0086] The abnormality analysis module 23 is configured to obtain the fan information corresponding to the control level, and the fan information includes: fan ID, wind force level; obtain the second actual flow of the sub-ventilation duct corresponding to the wind force ID; determine whether the second actual flow is consistent with the wind force level; if so, it is considered that the independent fan unit corresponding to the fan ID is working normally; if not, it is considered that the independent fan unit has an abnormality.

[0087] The step-by-step judgment mechanism adopted in this embodiment can assist astronauts or engineers to make a preliminary judgment on the current abnormal situation through flow monitoring of the main ventilation duct and the sub-ventilation duct, so as to facilitate rapid maintenance.

[0088] In some embodiments, at least one ventilation duct may also be provided with an automatic valve.

[0089] Preferably, in some embodiments, each sub-ventilation duct is provided with an automatic valve. At this time, when only some fans are started, the valves of the sub-ventilation ducts of the remaining fans can be closed accordingly.

Specifically, as Figure 3 and Figure 4As shown, the ventilation device comprises: a main body 1 wearable on a protective suit, the shell of the main body 1 comprises: a first support plate 11, a second support plate 12, and a first connecting plate 13 and a second connecting plate 14 for connecting the first support plate 11 and the second support plate 12; wherein, the two ends of the first support plate and the second support plate are sequentially provided with a support area I, a transition area II and a fitting area III; wherein, when the ventilation device is worn on the protective suit, the support area I corresponds to the back area of ​​the protective suit, the fitting area III corresponds to the waist side of the protective suit, and the heights of the support area, the transition area and the fitting area are sequentially reduced; and at least one vent is provided on the shell;

[0120] An integrated fan module, the integrated fan module comprising: at least two integrated fan units 16 arranged inside the support area I, the integrated fan unit 16 comprising: a fan 161, and a baffle 162 for sleeved on the outer periphery of the fan, a first space is formed inside the baffle, and the baffle is connected to a sub-ventilation duct; wherein at least two of the sub-ventilation ducts are connected to the main ventilation duct, and the main ventilation duct passes through the transition area II and can be connected to the protective clothing; wherein, when the fan is in working state, the baffle guides the drainage effect generated by the fan to be concentrated inside the first space, and is collected to the main ventilation duct via the sub-ventilation duct; the baffle is also provided with an air inlet corresponding to the vent;

[0121] A first connector 2 is provided at one of the fitting areas of the main body, and a second connector 3 matching with the first connector is provided at another fitting area, and the main body is worn on the protective clothing through the cooperation of the first connector and the second connector.

[0122] In some embodiments, the baffle may be a cylindrical housing.

[0123] In some embodiments, at least two of the integrated fan units are arranged in the support area I along the length direction of the main body.

[0124] In some embodiments, at least one of the vents is disposed at the second connection plate, and a third connection plate 15 is further disposed inside the housing; the third connection plate 15 is opposite to the at least one vent, and is enclosed with the second connection plate to form a second space, and the air inlet on the baffle is connected to the second space via an air inlet duct 17. The provision of the third connection plate can play an internal dust-proof role, and in the process of cooperating with the air inlet duct 17, can further enhance the stability of the independent operation of the fan.

[0125] Different from the traditional portable ventilation device, this application proposes a new type of wearable ventilation device. And different from the single fan design of the portable ventilation device, this application proposes a horizontal arrangement of multiple independent integrated fans to limit the height of the main body (i.e., reduce the height of the support area I that fits the back), thereby improving the wearing comfort of astronauts and reducing the wearing burden.

[0126] In addition, the independent ventilation duct design is conducive to the coordinated work of multiple fans. Among them, multiple fans can work synchronously in independent spaces without interfering with each other, and the number of fans turned on can be dynamically adjusted according to the actual wind force adjustment needs.

[0127] In some embodiments, since a plurality of independent integrated fans are centrally arranged inside the transition zone, the side edge of the main housing (such as Figure 5 As shown, its upper edge in the vertical direction is arranged to change in an arc.

[0128] For example, the shell includes left and right ends, and the sides of the left and right ends are sequentially formed with a first arc segment L1, a second arc segment L2 and a third arc segment L3, and the first arc segment, the second arc segment and the third arc segment correspond to a support area, a transition area and a fitting area, respectively. Among them, the height of the first arc segment L1 gradually decreases along the direction from its first end (i.e., the side connected to another first arc segment) to the second end (i.e., the side connected to the second arc segment), and two adjacent first arc segments L3 are combined to form a support area with a gentle protrusion, which is used to fit and support the back area of ​​the astronaut. The third arc segment L3 corresponds to the side of the astronaut's waist during the wearing process. The height of the third arc segment is less than the first arc segment (and the height of the fitting area is also less than the width of the support area). A transitional second arc segment L2 is provided between the third arc segment and the first arc segment. The sequential cooperation of the first, second and third arc segments can not only support the back, but also increase the degree of fit with the waist and back of the human body, thereby improving the wearing comfort.

[0129] The height of the arc segment refers to the vertical position of the subject.

[0130] The width of the fitting zone, transition zone and support zone refers to their length in the vertical direction.

[0131] In some embodiments, three integrated blower units may be provided.

[0132] In some embodiments, the protective suit is a space suit.

[0133] In some embodiments, Fig. 9As shown, an external ventilation duct 19 is also connected to the outside of the main body, the air inlet of the external ventilation duct 19 is arranged in the transition zone and connected to the main ventilation duct, and the air outlet of the external ventilation duct is connected to the protective clothing, so that when the target object wears the protective clothing and the ventilation device, the air outlet of the external ventilation duct is located at the connection between the buttocks and the outer side of the thigh of the target object.

[0134] In this embodiment, the layout of the air inlet and outlet of the external ventilation duct can reduce the length of the duct on the one hand, and reduce the interference of astronauts' ground activities (such as walking, turning, etc.) on the external ventilation duct on the other hand, and avoid bending and clogging of the external ventilation duct.

[0135] In some embodiments, a flow sensor and / or a pressure sensor is provided on the main ventilation duct or the external ventilation duct.

[0136] Preferably, in some embodiments, a flow sensor or a pressure sensor is arranged at the air outlet of the external ventilation duct.

[0137] In some embodiments, the first connecting member or the second connecting member comprises: a retractable connecting belt, one end of which is fixedly connected to the main body, and the other side of which is provided with a quick-release structure. In this embodiment, the retractable belt design can be suitable for astronauts of different body shapes.

[0138] In some embodiments, at least one of the bonding areas is provided with a battery module, and the battery module is used to supply power to the integrated fan module.

[0139] Preferably, in some embodiments, the battery module includes a plurality of batteries (or battery units) 23, and the plurality of batteries 23 are respectively connected to drive motors of a plurality of wind turbines to supply power to the drive motors.

[0140] Preferably, in some embodiments, battery modules are respectively arranged on both sides of the main body (such as the fitting area, or the area where the fitting area is connected to the transition area). When the astronaut wears the ventilation device, the battery modules are arranged on the side or back of the waist.

[0141] In this embodiment, multiple battery units are arranged on both sides of the waist, and multiple independent integrated fans are arranged in the middle (i.e., the support area), thereby forming a regionally concentrated and overall dispersed layout. This regionally concentrated and overall dispersed layout can further coordinate the key distribution of multiple units and ensure a sense of balance during wearing.

[0142] The layout of the fans and batteries in this embodiment significantly optimizes the utilization of the space inside the housing.

[0143] In some embodiments, a display module is provided at the connection of the two support areas, and the display module includes: a display screen provided on the first connecting plate, and a display device provided on the inner side of the support area and connected to the display screen.

[0144] In some embodiments, when the ventilation device is worn on the protective clothing, the second connecting plate is arranged downwards, wherein a plurality of ventilation holes are arranged on the second connecting plate.

[0145] In some embodiments, multiple ventilation areas are arranged on the second connecting plate corresponding to the multiple integrated fan units, and partitions are arranged between each ventilation area to divide the second space into multiple ventilation spaces to limit or reduce the circulation of airflow between the multiple ventilation spaces, and each ventilation space is respectively connected to the corresponding integrated fan unit through an air intake duct.

[0146] In some embodiments, the ventilation device further includes: a control module 18, which is used to control the operating state of each drive motor. A plurality of cables 22 extend from the control module 18, one end of the cable 22 is connected to the drive motor, and the other end is connected to the space suit. For example, the space suit is provided with an integrated control module to control the working state of the fan according to the internal state of the space suit, and the cable is used to connect the motor and the centralized control module to realize automatic control of the fan.
