Description

Technical Field

[0001] The invention relates to an air treatment device for isothermal dehumidification with cold and hot linkage, belonging to the field of HVAC, and specifically to a pair of medical goggles that adopts a semiconductor thermoelectric chip to realize the isothermal dehumidification function. Background Art

[0002] With the arrival and rapid spread of epidemic viruses such as the new coronavirus, medical goggles have become an indispensable medical equipment for medical staff. Due to the infectiousness of the new coronavirus, medical goggles must not only prevent the blood, body fluids and secretions of patients from splashing onto the eyes of medical staff when in close contact with patients, but also avoid the possibility of eye infection of medical staff caused by air transmission. In order to avoid eye infection caused by air transmission, the inside of the goggles must be sealed to prevent the goggles from exchanging air with the outside air. Under the condition that the ventilation efficiency inside the goggles is zero, facial sweat and eye breathing will cause excessive humidity in the goggles, causing condensation on the lenses; and the air circulation rate is low, causing facial discomfort to medical staff.

[0003] Existing automatic cleaning goggles mainly use a transmission mechanism to automatically remove mirror stains caused by external dust. However, such self-cleaning goggles also have obvious limitations. For example, such goggles cannot solve the problem of lens condensation caused by excessive internal air humidity, especially in cold winter, when the outdoor temperature is low, causing the lens temperature to be lower than the dew point temperature, which in turn causes severe condensation on the inner surface of the lens, making the medical staff's vision blurred. Secondly, such automatic cleaning goggles have a lag in removing stains, and cannot promote the flow of air inside the goggles. After searching, the Chinese patent publication number is CN 110632774 A, and the invention name is: A kind of goggles with automatic lens cleaning, the automatic cleaning function is mainly composed of a cleaning mechanism and an automatic control mechanism, and its purpose is to remove stains on the outer surface of the lens in bad weather.

[0004] Semiconductor thermoelectric chips can achieve cooling and heating at the same time. When the temperature of the cold end of the semiconductor thermoelectric chip is lower than the air dew point, the air inside the goggles can be condensed and dehumidified. Since the cooling capacity and heating capacity of the semiconductor thermoelectric chip are equivalent, the condensed air can be restored to its original temperature after being heated by the hot end of the semiconductor thermoelectric chip. In this air treatment process, the air humidity inside the goggles can be reduced and the temperature inside the goggles can be kept constant, thereby achieving the purpose of isothermal dehumidification. At the same time, the isothermal dehumidification process can effectively promote the flow of air inside the goggles and avoid facial discomfort for medical staff. Summary of the invention

[0005] The invention aims to prevent condensation on the inner surface of goggles and promote the flow of air inside the goggles, thereby providing goggles with an isothermal dehumidification function.

[0006] An air treatment device is designed inside the goggles, and the air treatment device includes an air inlet of the air treatment device, a semiconductor thermoelectric air treatment component and an air supply port of the air treatment device. The semiconductor thermoelectric air treatment component is mainly composed of a semiconductor thermoelectric chip, a condensation and dehumidification channel, an air heating channel, an axial flow fan power supply device and a rotating shaft component. The rotation of the axial flow fan makes the condensation and dehumidification channel in a negative pressure state, and the air heating channel in a positive pressure state. Under the negative pressure of the condensation and dehumidification channel, the humid air inside the goggles enters the condensation and dehumidification channel from the air inlet of the air treatment device. The cold air after condensation and dehumidification is heated through the air heating channel and then sent into the goggles from the air supply port of the air treatment device. This process not only realizes the isothermal dehumidification function by utilizing the cold and hot linkage of the semiconductor thermoelectric chip, but also promotes the circulation of air inside the goggles.

[0007] The axial flow fan and semiconductor thermoelectric chip inside the air handling device are connected to the power supply device. The speed of the axial flow fan and the cooling and heating capacity of the semiconductor thermoelectric chip can be changed through the stepless control knob to meet the thermal comfort requirements of medical staff in different environments. Secondly, the cooling and heating modes can be switched to achieve the function of enhanced dehumidification. The specific operation is: through the designed stepless control knob, the direction of the current is controlled to heat the lower surface of the semiconductor thermoelectric chip and cool the upper surface to heat the air in the condensation and dehumidification channel below, and then the direction of the current is changed to cool the lower surface of the semiconductor thermoelectric chip, so that the hot air is fully in contact with the cold surface for dehumidification, thereby improving the dehumidification effect.

[0008] The condensation and dehumidification channel is tilted downward as a whole, which is consistent with the flow direction of cold air, and can effectively reduce air flow resistance. At the same time, the hot end surface is tilted upward, and the flow cross-section of the air heating channel is gradually reduced, so that the hot end metal heat conduction plate of the semiconductor thermoelectric chip can fully heat the cold air, avoiding insufficient heating caused by the floating of hot air. At the same time, since the flow cross-section of the air heating channel is gradually reduced, the flow velocity of the air supply port of the air handling device is increased, and then the outflow wind speed collides with the frame of the goggles to form a downward attached jet, which can effectively avoid condensation on the lenses.

[0009] The lower surface of the metal heat conductive plate at the cold end of the semiconductor thermoelectric chip and the upper surface of the arc-shaped guide plate are provided with a hydrophobic coating to facilitate the shedding and flow of condensed water. The arc-shaped guide plate is bent downward from both sides to the middle to form a channel-like passage to facilitate the flow of condensed water from the middle of the arc-shaped guide plate to the moisture absorption unit.

[0010] The semiconductor thermoelectric chip can be rotated under the drive of the transmission mechanism to increase the inclination angle of the semiconductor thermoelectric chip, so that the condensed water can fall off quickly, prevent the formation of film condensation, reduce the heat exchange thermal resistance between the humid air and the cold end metal heat conduction plate, and increase the condensation and dehumidification effect of the air.

[0011] The goggles with isothermal dehumidification function include a glasses bracket structure, which is made of rubber and is a pair of C-shaped structures located on both sides of the goggles frame. When in use, people in need can directly install myopia glasses on the glasses bracket of the goggles, which not only reduces the burden on personnel, but also ensures the stability of the wearer's glasses.

[0012] The purpose of the present invention is achieved through the following technical ideas:

[0013] The internal space of the goggles is regarded as a small micro space, and the air handling device performs air conditioning inside the goggles. The rotation of the axial flow fan inside the air handling device makes the condensation and dehumidification channel in a negative pressure state, and the air heating channel in a positive pressure state. The humid air inside the goggles enters the condensation and dehumidification channel from the air inlet of the air handling device under the negative pressure of the condensation and dehumidification channel. The cold air after condensation and dehumidification at the cold end of the semiconductor thermoelectric chip enters the air heating channel. The cold air is heated by the hot end metal heat conduction plate to restore it to the inlet temperature, thereby achieving the purpose of isothermal dehumidification.

[0014] During the condensation and dehumidification process, condensed water will be generated on the lower surface of the cold-end metal heat conduction plate of the semiconductor thermoelectric chip, and the condensed water will fall off to the upper surface of the arc-shaped guide plate. In order to reduce the flow resistance of condensed water in the cold-end metal heat conduction plate and the arc-shaped guide plate, the lower surface of the cold-end metal heat conduction plate and the upper surface of the arc-shaped guide plate are provided with a hydrophobic coating to collect the condensed water. The arc-shaped guide plate is bent from both sides to the middle to form a channel-like flow channel. The condensed water flows through the channel-like flow channel to the moisture-absorbing paper towels of the moisture absorption unit. When medical staff take a break, they can open the wet wipes storage drawer of the moisture absorption unit and replace the paper towels after absorption.

[0015] In order to prevent the condensed water from forming a film condensation on the surface of the cold-end metal heat conduction plate, increasing the heat transfer resistance and reducing the condensation effect, the lever on the upper surface of the goggles is pushed to drive the transmission mechanism to increase the inclination angle of the semiconductor thermoelectric chip so that the condensed water can fall off quickly.

[0016] The advantages of the goggles with isothermal dehumidification function of the present invention are:

[0017] First, the present invention uses the cold-end cooling and hot-end heating functions of the semiconductor thermoelectric chip to achieve isothermal dehumidification of humid air, avoiding condensation of humid air on the inner surface of the lens and affecting the vision of medical staff, and at the same time, promoting the flow of air inside the goggles.

[0018] Second, the present invention adopts the downward tilt of the lower condensation and dehumidification channel and the upward tilt of the upper air heating channel, which can effectively ensure the smooth movement of the lower cold air and the upper hot air. At the same time, the air passes through the lower condensation and dehumidification channel and the upper air heating channel in sequence, which is conducive to promoting the heat dissipation of the hot end of the semiconductor thermoelectric chip and improving the working efficiency of the semiconductor thermoelectric chip.

[0019] Third, the present invention jointly controls the axial flow fan and the semiconductor thermoelectric chip through a power supply device through a stepless control knob, which can not only realize the adjustment of the cooling and heating amount of the semiconductor thermoelectric chip, but also control the switching of the cooling surface and the heating surface, so as to realize condensation on the contact with the cold surface by switching the current direction immediately after the air is heated, thereby enhancing the effect of air dehumidification.

[0020] Fourth, the dehumidification assembly of the present invention is small in size and low in power, and is integrated with the goggles, with a high degree of integration. At the same time, the glasses holder provided inside can be used by people who need to wear myopia glasses.

[0021] In summary, the present invention fully utilizes the cooling and heating functions of the semiconductor thermoelectric chip with cold and hot linkage, achieves the effect of isothermal dehumidification, and has the characteristics of compact structure and cold and hot linkage.

[0029] The following will be combined Figure 1-5 The specific embodiments of the present invention are further described in detail. The embodiments are only preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto.

[0030] like Figure 1 As shown, a pair of goggles with isothermal dehumidification function, the goggles include a goggles body 1, an air treatment device 2, a moisture absorption unit 3 and a transmission cavity 4, the goggles body is mainly composed of a lens 101, a frame 102, a mask 103, a belt bolt 104, a rectangular groove 105, a stepless control knob 106 and a glasses holder 107, wherein the lens 101, the frame 102 and the mask 103 are used to form a closed space for the goggles, the belt bolt 104 is used to connect the bandage to fix the goggles to the eyes of the medical staff, the purpose of the rectangular groove is to provide a channel for translation, the stepless control knob 106 is used to adjust the speed of the axial flow fan and the cooling and heating capacity of the semiconductor thermoelectric chip to realize the switching of the cooling and heating modes, and the glasses holder 107 can provide a support for the fixation of the myopic glasses in the goggles.

[0031] The air treatment device 2 is located inside the goggles and is in the shape of a cuboid. The air treatment device 2 is fixed to the top of the mask 103 through the upper surface of the shell 201, and the horizontal distance between the front surface and the frame 102 is 10 mm.

[0032] like Figure 2 As shown, it is a schematic diagram of the structure of the air treatment device 2, which includes an air inlet 202 of the air treatment device, an internal semiconductor air treatment component and an air supply port 206 of the air treatment device, and a desiccant unit 3 is embedded on the lower side of the air treatment device, and a transmission cavity 4 is attached to the left and right sides.

[0033] The transmission cavity 4 and the air treatment device 2 share the upper and lower surfaces of the housing 201 of the air treatment device 2, so that the transmission cavity and the air treatment device form a whole. The air inlet 202 of the air treatment device is located on both sides of the air treatment device 2, has a quadrilateral shape, and passes through the transmission cavity 4 to be connected to the semiconductor thermoelectric air treatment component inside the air treatment device 2.

[0034] like Figure 3 As shown, a schematic diagram of a semiconductor thermoelectric air treatment component, the semiconductor thermoelectric air treatment component includes a semiconductor thermoelectric chip 203, a condensation and dehumidification channel 204, an air heating channel 205, an axial flow fan 207 and a battery 219. The semiconductor thermoelectric chip 203 and the axial flow fan 207 are connected to the battery 219. The purpose of the semiconductor thermoelectric chip is to provide a cold and heat source for the semiconductor thermoelectric air treatment component. The main function of the condensation and dehumidification channel 204 is to condense and dehumidify the humid air, and the main function of the air heating channel 205 is to heat the dehumidified cold air to restore it to its original temperature. The axial flow fan 207 is mainly used to realize the flow of air inside the air treatment device.

[0035] The semiconductor thermoelectric chip 203 is placed at an angle, and the lower surface of the semiconductor thermoelectric chip is the cold end. The cold end of the semiconductor thermoelectric chip is provided with a cold end metal heat conductive plate 208. The upper surface of the semiconductor thermoelectric chip 203 is the hot end. The hot end of the semiconductor hot end chip 203 is provided with a hot end metal heat conductive plate 209. The main purpose of the cold end metal heat conductive plate 208 and the hot end metal heat conductive plate 209 is to evenly distribute the cooling capacity and heating capacity of the semiconductor thermoelectric chip 203.

[0036] The semiconductor thermoelectric chip 203 is provided with a shaft component on both sides. One side of the shaft component is glued to the semiconductor thermoelectric chip 203 through the shaft connection section, and the other side of the shaft component passes through the inner wall of the transmission cavity and is connected to the transmission mechanism 4.

[0037] The condensation and dehumidification channel 204 is composed of a cold-end metal heat-conducting plate 208 of the semiconductor thermoelectric chip 203 and an arc-shaped guide plate 212, and the arc-shaped guide plate 212 is located below the cold-end metal heat-conducting plate 208, and the entire condensation and dehumidification channel 204 is tilted downward as a whole. When the humid air in the goggles enters the condensation and dehumidification channel 203 from the air inlet 202 of the semiconductor air treatment device, it contacts the cold-end metal heat-conducting plate 208 of the semiconductor thermoelectric chip 203, and the cold-end cooling capacity of the semiconductor thermoelectric chip 203 makes the temperature of the cold-end metal heat-conducting plate 208 lower than the dew point temperature, thereby achieving the effect of condensation and dehumidification.

[0038] The arc guide plate 212 is used to limit the flow cross-section of the condensation and dehumidification channel 204, so that the humid air can fully exchange heat with the cold end metal heat conductive plate 208. In addition, the arc guide plate 212 is bent from both sides to the middle to form a channel-like channel for collecting condensed water.

[0039] The lower surface of the cold-end metal heat conducting plate 208 and the upper surface of the arc-shaped guide plate 212 are both provided with a hydrophobic coating to prevent condensed water from forming a film-like condensation on the lower surface of the cold-end metal heat conducting plate 208 and increasing the heat exchange thermal resistance. At the same time, the flow resistance of condensed water on the arc-shaped guide plate 212 can be reduced.

[0040] A wind shield 213 is provided on the lower side of the arc guide plate 212 to prevent the cold air after condensation and dehumidification from entering the bottom of the arc guide plate 209 and forming a flow dead zone. The side of the wind shield 213 that contacts the arc guide plate 212 is a curve that is adapted to the arc guide plate 212 so that the wind shield 213 and the arc guide plate 212 are tightly connected.

[0041] The lower side of the condensation and dehumidification channel 204 is provided with an air outlet 214 of the condensation and dehumidification channel, and the wet air flows out from the air outlet 214 of the condensation and dehumidification channel after condensation and dehumidification. The cold air after flowing out will enter the air heating channel 205 under the action of the axial flow fan 206. When the cold air flows from the air outlet 214 of the condensation and dehumidification channel to the air inlet 216 of the air heating channel, in order to reduce the air flow resistance, a semicircular arc guide plate 215 is provided on the upper side of the air outlet 214 of the condensation and dehumidification channel.

[0042] The axial flow fan 206 is fixed to the upper surface of the shell 201 of the air treatment device 2 by the fan fixing rod 217. By adjusting the fan fixing rod 217, the blades 218 of the axial flow fan are perpendicular to the hot end metal heat conductive plate 209 of the semiconductor thermoelectric chip 203. When the axial flow fan 206 rotates, the condensation and dehumidification channel 204 is at negative pressure, and the air heating channel 205 is at positive pressure.

[0043] The air heating channel 205 is composed of an air supply port 202 of an air treatment device, a hot end metal heat conducting plate 209 and a shell 201 of the air treatment device. The cold air after condensation and dehumidification is heated by the hot end metal heat conducting plate 209 and then delivered into the goggles through the air supply port 206 of the air treatment device.

[0044] The air outlet 206 of the air handling device is rectangular in shape, located at the end of the air heating channel 205, and is parallel to the mirror frame 102 in space, with a horizontal spacing of 10 mm.

[0045] The semiconductor thermoelectric chip 203 and the metal heat conductive plate 209 at the hot end are placed at an angle, so that the flow cross-section of the air heating channel 205 is gradually reduced, which in turn causes the outflow velocity of the air supply port 206 of the air handling device to increase. The jetted air collides with the frame 102 to form downward attached ventilation, which can effectively eliminate condensation on the lens 101.

[0046] The storage battery 219 is placed in the battery slot 220, and the battery slot is arranged at the center of the upper surface of the housing 201 of the air treatment device 2. The cooling capacity and heating capacity of the semiconductor thermoelectric chip 203 and the rotation speed of the axial flow fan 206 can be changed by the stepless control knob 106 to meet the thermal comfort requirements of medical staff in different environments. Secondly, the switching of the cooling and heating modes can be realized to enhance the dehumidification function. The stepless control knob 106 has a continuous scale from negative current to positive current, and the positive and negative currents represent different current directions. For example, when the cooling capacity needs to be increased, the current value can be increased. When the cooling and heating modes need to be switched, the stepless control knob 106 can be turned to the scale of the opposite current value.

[0047] like Figure 4 As shown, it is a structural schematic diagram of the desiccant unit, which includes a paper towel storage drawer, a desiccant paper towel 306 and a switch screw 305. The paper towel storage drawer is mainly composed of a drawstring 301, a front baffle 302, two side panels 303 and a bottom plate 304. The desiccant paper towel 306 is placed on the upper surface of the bottom plate 304. At the same time, the lower side projection of the arc guide plate 212 also happens to fall on the desiccant paper towel 306, so that the condensed water flowing down from the arc guide plate 212 can fall on the desiccant paper towel 306.

[0048] The switch screw 305 passes through the left transmission cavity 4 and contacts the left side plate 303 of the paper towel storage drawer to fix the paper towel storage drawer. When replacing paper towels, the switch screw 305 is first rotated to separate the switch screw 305 from the left side plate 303 of the paper towel storage drawer, and then the paper towel storage drawer is pulled open by the pull belt 301 to replace the moisture-absorbing paper towel 306. When replacing the moisture-absorbing paper towel 306, in order to quickly remove the condensed water on the cold-end metal heat-conducting plate 208, the inclination angle of the cold-end metal heat-conducting plate 208 can be adjusted through the transmission mechanism 4.

[0049] like Figure 5 As shown, it is a schematic diagram of the transmission structure of the semiconductor thermoelectric chip. The end of the rotating shaft 219 is connected to the pinion 410 in the transmission cavity 4. The pinion 410 is connected to the pinion 407 through the chain 409. The pinion 407 and the large gear 408 are on the same gear shaft 405. The end of the gear shaft 405 is fixed to the outer wall of the transmission cavity through the bearing 406 to reduce the rotation resistance of the gear shaft 405.

[0050] The large gear 408 is meshed with the spur teeth 404, and a lever 402 is provided on the upper surface of the spur teeth 404. The rectangular groove 401 of the transmission cavity of the lever 402 and the rectangular groove 106 on the upper surface of the goggles are consistent in size, and the length and width of the two rectangular grooves are smaller than the upper surface of the spur teeth 404 to prevent outside air from entering the interior of the goggles. When the lever translates on the upper surface of the goggles, it can drive the rotation of the semiconductor thermoelectric chip.
