Description

Technical Field

[0001] This invention relates to a respirator, specifically a respirator with detection function that is waterproof and breathable. Background Technology

[0002] With the advancement of science and technology, people's demand for electricity is increasing, and server racks are an indispensable part of the power grid. They play an important role and generate a lot of heat in the process.

[0003] Currently used waterproof and breathable valves in server racks can balance the atmospheric pressure inside and outside the rack, but they cannot prevent moisture from entering. Condensation occurs in environments with high humidity and large temperature differences. The formation of condensation inside the rack is mainly due to excessive moisture trapped inside, failing to escape. Facing temperature fluctuations in the natural environment, condensation forms on the inner walls of the rack, and in extreme cases, water droplets may form on the walls. If the rack becomes saturated with moisture, and the temperature continues to drop, the moisture will condense out of the air, corroding materials inside the rack and potentially causing short circuits and burnout of circuit boards – a very serious consequence. Therefore, a device is needed that can detect humidity and temperature inside the rack, balance the atmospheric pressure, and provide ventilation. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides a respirator with detection capabilities that is waterproof and breathable. The device is equipped with an openable damper and a fan. The damper automatically opens when the internal fan is activated and automatically closes when the fan is deactivated. When conditions conducive to condensation are detected within the device, the fan and damper are activated, allowing the expulsion of hot or humid air.

[0005] The technical solution of the present invention is: a respirator with detection function that is waterproof and breathable, comprising a body;

[0006] The bottom of the body can be detachably and fixedly connected to the cabinet;

[0007] The top opening of the body has a detachable and fixed cover with a waterproof and breathable valve. The cover has a threaded hole in which the waterproof and breathable valve is installed. The waterproof and breathable valve can balance the internal and external atmospheric pressure and prevent water from entering.

[0008] The body is equipped with an integrated circuit board, which integrates a first humidity sensor for detecting the humidity inside the cabinet, a first temperature sensor for detecting the temperature inside the cabinet, an I / O interface for connecting to the control unit inside the cabinet, and a respirator control unit; the main function of the respirator control unit is to output operating instructions for the internal devices of the respirator according to the actual situation.

[0009] A fan is installed inside the body, and the fan is connected to the integrated circuit board via a signal line;

[0010] The side opening of the body is provided, and the damper assembly is detachably and fixedly installed on the side opening of the body; the damper assembly includes a damper, a damper push rod and a damper sleeve; a push rod support frame is provided inside the damper sleeve, one end of the damper push rod is radially limited and axially movable and fixed inside the damper sleeve through the push rod support frame, and the other end of the damper push rod is fixedly connected to the damper, the damper can be sealed at the opening on the outside of the damper sleeve, and the threaded opening on the inside of the damper sleeve passes through the side opening of the body and is fixedly connected to the side opening of the body through the damper sleeve fixing nut;

[0011] The body contains a motor actuator, which is connected to an integrated circuit board via a signal line. The actuator's shaft is connected to a connecting rod assembly, which in turn is connected to a damper push rod. The rotation of the motor actuator drives the connecting rod assembly to swing, further causing the damper push rod to move axially back and forth, thus opening and closing the damper. Inside the respirator, a motor actuator rocker arm is mechanically connected to a connecting rod, which is also mechanically connected to the damper push rod. When the actuator rocker arm swings, it pushes the connecting rod, which in turn pushes the damper out of the sleeve, opening the device. This movement opens the device by pushing the damper open, allowing the fan to expel internal air. When the device closes, the damper is pulled back, and the sealing ring on the damper contacts the damper sleeve, achieving a tight seal and waterproof effect.

[0012] The outer surface of the body is provided with a sensor mounting position, in which a second humidity sensor for detecting the humidity outside the cabinet and a second temperature sensor for detecting the temperature outside the cabinet are installed. The second humidity sensor and the second temperature sensor are connected to the integrated circuit board via signal lines.

[0013] Furthermore, the bottom of the body is provided with a connecting pipe with external threads, which, in conjunction with a nut, can fix the respirator body to the cabinet.

[0014] Furthermore, a sealing ring is provided on the inner side of the damper. The sealing ring on the damper contacts the damper sleeve to achieve a tight and waterproof effect.

[0015] The beneficial effects of this invention are: when the respirator is in a non-working state, the vent is closed, and at this time, the sealing components of the respirator achieve IP67 waterproof and dustproof function; when the internal and external sensors of the respirator reach the preset value, and the cabinet needs the respirator to work to avoid the generation of condensate inside, the motor actuator works, which indirectly drives the movement of the damper, and the fan realizes the exchange of internal and external air, and quickly eliminates the high temperature and high humidity air inside the cabinet, solving the difficulties of condensation inside the cabinet and the difficulty of heat exchange between the inside and outside.

[0016] This invention solves most heat exchange and anti-condensation problems inside and outside server racks. The rack can autonomously control the various functions of the respirator, which can be controlled using the respirator's built-in program. The intelligent respirator can be used in numerous heat-generating scenarios. It integrates sensor technology, intelligent switches, and a novel waterproof and breathable valve design. Its real-time control and intelligent data processing system, centered on a microcontroller, determines different conditions and issues different instructions. Through the opening and closing of the fan and damper, it achieves the effects of exhaust, heat dissipation, ventilation, and anti-condensation. The respirator's control board can operate with low power consumption for extended periods and has an alarm function, greatly improving the safety and lifespan of equipment within the rack.

Detailed Implementation

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a respirator with detection function that is waterproof and breathable includes a body 1.

[0021] The bottom of the body 1 is provided with a connecting pipe with external threads. The respirator body can be fixed to the cabinet by the cooperation of the connecting pipe with the nut. When the body 1 and the installed cabinet are fixed by fasteners, relevant sealing parts are provided on the fixing surface.

[0022] The top opening of the body 1 allows for a fixed connection between the internal threads of the cover 11, which has a waterproof and breathable valve, and the external threads of the top opening. The cover 11 also has threaded holes for the waterproof and breathable valve, which balances the internal and external atmospheric pressure and prevents water from entering.

[0023] An integrated circuit board 9 is installed inside the body 1. The integrated circuit board 9 integrates a first humidity sensor for detecting the humidity inside the cabinet, a first temperature sensor for detecting the temperature inside the cabinet, an I / O interface (input / output interface) for connecting to the control unit inside the cabinet, and a respirator control unit. The main function of the respirator control unit is to output operating commands for the internal devices of the respirator according to actual conditions. By connecting to the relevant control units of the cabinet through the I / O interface, the cabinet can achieve autonomous control of the invention.

[0024] A fan 2 is installed inside the body 1, and the fan 2 is connected to the integrated circuit board 9 via a signal line.

[0025] The body 1 has a side opening, and the damper assembly is detachably and fixedly installed on the side opening. The damper assembly includes a damper 3, a damper push rod 4, and a damper sleeve 5. A push rod support frame is provided inside the damper sleeve 5. One end of the damper push rod 4 is radially limited and axially movable inside the damper sleeve 5 through the push rod support frame. The other end of the damper push rod 4 is threaded and fixedly connected to the threaded hole on the inner surface of the damper 3. The damper 3 can seal the outer opening of the damper sleeve 5. The threaded opening on the inner side of the damper sleeve 5 passes through the side opening and is fixedly connected to the side opening of the body through the damper sleeve fixing nut 6.

[0026] A motor actuator 7 is installed inside the body 1, and the motor actuator 7 is connected to the integrated circuit board 9 via a signal line. The rotating shaft of the motor actuator 7 is connected to a connecting rod assembly 8, and the connecting rod assembly 8 is connected to a damper push rod 4. The rotation of the motor actuator 7 drives the connecting rod assembly 8 to swing, which in turn drives the damper push rod 4 to move axially back and forth, thereby opening and closing the damper 3. The motor actuator rocker arm and connecting rod inside the respirator are mechanically connected, and the connecting rod is mechanically connected to the damper push rod. When the actuator rocker arm swings, the rocker arm pushes the connecting rod, and the connecting rod and the damper push rod are pushed out of the sleeve, and the device opens. The movement is that when the device opens, the damper is pushed open, and the fan will expel the internal air. When the device closes, the damper is pulled back, and the sealing ring on the damper contacts the damper sleeve, achieving a sealing and waterproof effect.

[0027] The body 1 is equipped with a structural air supply damper assembly, a motor actuator 7, a fan 2, and an integrated circuit board 9.

[0028] The outer surface of the body 1 is provided with a sensor mounting position 10. A second humidity sensor for detecting the external humidity of the cabinet and a second temperature sensor for detecting the external temperature of the cabinet are installed in the sensor mounting position 10. The second humidity sensor and the second temperature sensor are connected to the integrated circuit board 9 through signal lines.

[0029] When the respirator is installed in a cabinet or other possible usage scenarios, the internal control unit will determine whether to activate the respirator.

[0030] When the respirator is closed, the damper assembly is in the closed state, which can achieve waterproof and dustproof protection. The waterproof vent valve on the respirator balances the internal and external atmospheric pressure. At the same time, the waterproof vent valve can also achieve waterproof and dustproof protection during the outward ventilation process.

[0031] When the respirator is turned on, the control unit will control the fan 2 and the motor actuator 7 to start simultaneously. The motor actuator 7 will control the linkage assembly to push the damper open. The fan 2 will drive the air in the cabinet and discharge it from the damper assembly, thereby achieving the functions of exhaust, heat dissipation, ventilation, and anti-condensation by removing the high temperature and humidity air inside.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
