Description

Technical Field

[0001] The present invention relates to the technical field of intelligent heating, and particularly to an eyelid hot compress device. Background Art

[0002] In today's information society, electronic products such as mobile phones and computers have become the main carriers of information dissemination and entertainment. Whether in life or work, people almost have to use electronic products such as mobile phones and computers. While electronic products bring convenience to people, they also cause greater harm to the eyes.

[0003] For example, staring at an electronic screen for a long time will greatly reduce the number of blinks, making the tear film unable to be evenly distributed on the eyeball with the blinking action, resulting in the accumulation of oil in the meibomian glands that cannot be discharged. Over time, it will cause the degradation of meibomian gland function and lead to dry eye disease.

[0004] Existing eyelid hot compress devices only have two states, one is the working state and the other is the non - working state. In the working state, heating is carried out at the same target temperature, and in the non - working state, no heating is carried out. Although it is the same target temperature, the actual heating effects are different for different users and different environments. Therefore, the hot compress effect of existing eyelid hot compress devices fluctuates greatly. Summary of the Invention

[0062] In order to better explain the present invention for easy understanding, the present invention will be described in detail below with reference to the drawings through specific embodiments.

[0063] Existing eyelid hot compress devices only have two states, one is the working state and the other is the non-working state. During the working state, heating is carried out at the same target temperature, and no heating is carried out during the non-working state. Although it is the same target temperature, the actual heating effects are different for different users and different environments. Therefore, the hot compress effects of existing eyelid hot compress devices fluctuate greatly.

[0064] To solve the above problems, the present invention provides an eyelid hot compress device, which includes: a parameter acquisition module, a control module, and a hot compress working module; the parameter acquisition module includes: a temperature sensor, a humidity sensor, and a pressure sensor; the hot compress working module includes: a heating plate, an airbag, and an ultrasonic atomization sheet; wherein, the parameter acquisition module is connected to the control module, and the control module is connected to the hot compress working module; the temperature sensor is used to monitor the eyelid temperature Tlid and the temperature Tin of the internal environment of the device in real time; the humidity sensor is used to monitor the humidity Hin of the internal environment of the device in real time; the pressure sensor is used to monitor the pressure Flid received by the eyelid in real time; the control module is used to control the hot compress working module according to Tlid, Tin, Hin, and Flid; the heating plate is used to heat the eyelid according to the control of the control module; the airbag is used to pressurize the eyelid according to the control of the control module; the ultrasonic atomization sheet is used to humidify the eyelid according to the control of the control module. The device provided by the present invention can realize flexible adjustment of temperature during the working process, ensuring the heating effect.

[0065] See Figure 1 , the eyelid hot compress device provided in this embodiment includes: a parameter acquisition module,

[0066] a control module, and a hot compress working module.

[0067] Among them, the parameter acquisition module is connected to the control module, and the control module is connected to the hot compress working module.

[0068] 1. Parameter acquisition module

[0069] See Figure 2 As shown, the parameter acquisition module includes: a temperature sensor, a humidity sensor, and a pressure sensor.

[0070] The temperature sensor is used to monitor the eyelid temperature Tlid and the temperature Tin of the internal environment of the device in real time.

[0071] The humidity sensor is used to monitor the humidity Hin of the internal environment of the device in real time.

[0072] The pressure sensor is used to monitor the pressure Flid received by the eyelid in real time.

[0073] 2. Hot compress working module

[0074] See Figure 2 As shown, the hot compress working module includes: a heating plate, an airbag, and an ultrasonic atomization sheet.

[0075] The heating plate is used to heat the eyelid according to the control of the control module.

[0076] The airbag is used to pressurize the eyelid according to the control of the control module.

[0077] An ultrasonic atomizing sheet, which is used to humidify the eyelids according to the control of a control module.

[0078] 3. Control module

[0079] A control module, which is used to control a hot compress working module according to Tlid, Tin, Hin, and Flid.

[0080] See Figure 2 As shown, it is used to determine a target temperature according to Tlid and Tin, determine a target humidity according to Hin and the target temperature, determine a target pressure according to Flid, the target temperature, and the target humidity, control a heating plate according to the target temperature, control an airbag according to the target pressure, and control an ultrasonic atomizing sheet according to the target humidity.

[0081] Among them, 1) The process of determining the target temperature according to Tlid and Tin is as follows:

[0082] 101. Determine whether Tlid is less than a preset minimum temperature threshold Tmin.

[0083] Among them, Tmin is the lowest temperature capable of melting meibomian gland oil, such as the melting point of meibomian gland oil. For example, Tmin = 42 °C.

[0084] 102-1. If Tlid < Tmin, then determine the target temperature as Tmin.

[0085] 102-2. If Tlid ≥ Tmin, then determine the relationship between Tlid and Tmax.

[0086] If Tlid ≥ Tmax, then determine the target temperature as Tmax.

[0087] If Tlid < Tmax, then determine the first temperature difference ΔT1 = Tlid - Tin, and determine the target temperature according to ΔT1.

[0088] Among them, Tmax is a preset maximum temperature threshold.

[0089] The determination method of Tmax is that after the user pre-tests the eyelid hot compress device, starting from Tmin, the preset temperature step (such as 0.1 °C) is increased every preset time step (such as 10 seconds). When the user feels that the temperature is high, a temperature stop signal is sent to the eyelid hot compress device, and the temperature at this time is T1. If T1 ≤ the highest temperature at which meibomian gland oil melts (such as 45 °C), then Tmax = T1. If T1 > the highest temperature at which meibomian gland oil melts (such as 45 °C), then Tmax = the highest temperature at which meibomian gland oil melts.

[0090] In addition, the first temperature difference ΔT1 is the temperature difference between the current eyelid temperature Tlid (i.e., the temperature inside the eyelid) and the temperature Tin of the internal environment of the device (i.e., the temperature outside the eyelid). The process of determining the target temperature based on ΔT1 can be as follows:

[0091] If ΔT1 = 0, it means that the current eyelid temperature Tlid is the same as the temperature Tin of the internal environment of the device, that is, the temperatures inside and outside the eyelid are the same. Then, the target temperature is determined to be Tlid, which means the temperature does not change and remains the current temperature.

[0092] If ΔT1 > 0, it means that the current eyelid temperature Tlid is higher than the temperature Tin of the internal environment of the device, that is, the temperature inside the eyelid is higher than the temperature outside the eyelid.

[0093] When the temperature inside the eyelid is higher than the temperature outside the eyelid, during the heating process of the eyelid, there will be a situation where heat flows from the inside of the eyelid to the outside of the eyelid, that is, temperature loss due to the low external environment temperature. At this time, it will be adjusted upward based on the current eyelid temperature Tlid. The greater the temperature difference between the inside and outside of the eyelid, the greater the adjustment amplitude.

[0094] Therefore, if ΔT1 > 0, the following steps are executed:

[0095] 201. Determine the second temperature difference ΔT2 = Tmax - Tlid.

[0096] Since the maximum heating temperature of the eyelid hot compress device provided in this embodiment is Tmax, the second temperature difference ΔT2 represents the maximum amplitude of the upward temperature adjustment.

[0097] 202. Determine the first adjustment coefficient A1 = ΔT1 / α.

[0098] Where α is the adjustment precision. This precision is preset. For example, if it is adjusted in 2 gears, then α = 0.5; if it is adjusted in 3 gears, then α = 0.25, etc.

[0099] The first adjustment coefficient A1 represents the temperature difference adjusted under the unit adjustment precision.

[0100] 203. Determine the target temperature as min{Tlid × [1 + A1 × ΔT2 / (Tmax - Tmin)], Tmax}.

[0101] Where min{} is the minimum function.

[0102] A1 × ΔT2 / (Tmax - Tmin) is the target temperature adjustment ratio under the conditions of the maximum amplitude of the upward temperature adjustment (i.e., ΔT2) and the temperature difference adjusted under the unit adjustment precision (i.e., A1).

[0103] In addition, the maximum target temperature is Tmax. If the calculated Tlid × [1 + A1 ×

[0104] ΔT2 / (Tmax - Tmin)] > Tmax, then the target temperature is Tmax.

[0105] If ΔT1 < 0, it indicates that the current eyelid temperature Tlid is the same as the temperature Tin of the internal environment of the device, that is, the temperature inside the eyelid is lower than the temperature outside the eyelid.

[0106] When the temperature inside the eyelid is lower than the temperature outside the eyelid, during the heating process of the inside of the eyelid, there will be a situation where heat flows from the outside of the eyelid to the inside of the eyelid. That is, due to the high temperature of the external environment compensating for the temperature, at this time, it will be adjusted downward based on the current eyelid temperature Tlid. The greater the temperature difference between the inside and outside of the eyelid, the greater the adjustment amplitude.

[0107] If ΔT1 < 0, then perform the following steps:

[0108] 301. Determine the third temperature difference ΔT3 = Tlid - Tmin.

[0109] Since the minimum heating temperature of the eyelid hot compress device provided in this embodiment is Tmin, the third temperature difference ΔT3 represents the maximum amplitude of the temperature adjustment downward.

[0110] 302. Determine the second adjustment coefficient A2 = (lid / Tmax) / (Tin / Tmax).

[0111] The second adjustment coefficient A2 represents the degree to which the temperature inside the eyelid is lower than the temperature outside the eyelid. The greater this degree, the greater the adjustment amplitude required.

[0112] 303. Determine the target temperature as max{Tlid × [1 - A2 × ΔT3 / (Tmax - Tmin)], Tmin}.

[0113] Where max{} is the maximum function.

[0114] A2 × ΔT3 / (Tmax - Tmin) is the target temperature adjustment ratio under the conditions of the maximum amplitude of the temperature adjustment downward (i.e., ΔT3) and the degree to which the temperature inside the eyelid is lower than the temperature outside the eyelid (i.e., A2).

[0115] In addition, the minimum target temperature is Tmin. If the calculated Tlid × [1 - A2 ×

[0116] ΔT3 / (Tmax - Tmin) < Tmin, then the target temperature is Tmin.

[0117] In addition, 2) The process of determining the target humidity according to Hin and the target temperature is as follows:

[0118] (1) If Hin ≥ Hmax, then determine the target humidity as Hmax.

[0119] Wherein, Hmax is the pre-set maximum humidity threshold, for example, Hmax is 65%.

[0120] That is to say, if the humidity Hin of the internal environment of the device is greater than the maximum humidity, it will be reduced to the maximum humidity Hmax.

[0121] (2) If Hin < Hmin, then determine the target humidity as Hmin.

[0122] Wherein, Hmin is the pre-set minimum humidity threshold, for example, Hmin is 45%.

[0123] That is to say, if the humidity Hin of the internal environment of the device is less than the minimum humidity, it will be increased to the minimum humidity Hmin.

[0124] (3) If Hmin ≤ Hin < Hmax, then the adjustment of humidity is related to temperature. The higher the temperature, the greater the consumption of water evaporation, etc. Therefore, the following steps will be executed:

[0125] 401. Determine the fourth temperature difference ΔT4 = target temperature - Tlid.

[0126] The fourth temperature difference ΔT4 represents the degree of temperature adjustment.

[0127] 402-1. If ΔT4 ≤ 0, then determine the target humidity as Hin.

[0128] If ΔT4 ≤ 0, it means that the temperature is adjusted downward or not adjusted, which will not affect the humidity. Therefore, the target humidity is the humidity Hin of the internal environment of the device, that is, the current humidity remains unchanged.

[0129] 402-2. If ΔT4 > 0, then determine the target humidity as Hin + (Hmax - Hin) ×

[0130] (ΔT4 / Tlid).

[0131] If ΔT4 > 0, it means that the temperature is adjusted upward, which will increase the demand for moisture and thus bring about an increase in humidity. Therefore, the target humidity is Hin + (Hmax - Hin) × (ΔT4 / Tlid).

[0132] In addition, during the heating and humidifying process, applying pressure can help the discharge of the oil in the meibomian gland. The higher the temperature and the greater the humidity, the easier the meibomian gland oil melts and the easier it is to discharge. Then the pressure can be slightly reduced, otherwise it will increase. Therefore, the process of determining the target pressure according to Flid, the target temperature, and the target humidity is as follows:

[0133] 501. Determine the fourth temperature difference ΔT4 = target temperature - Tlid, and determine the first humidity difference ΔH1 = target humidity - Hin.

[0134] The fourth temperature difference ΔT4 characterizes the degree of temperature adjustment. The first humidity difference ΔH1 characterizes the degree of humidity adjustment.

[0135] 502 - 1. If ΔT4 = 0 and ΔH1 = 0, then determine the target pressure as Flid.

[0136] If ΔT4 = 0 and ΔH1 = 0, it means that both the adjusted temperature and humidity remain unchanged. At this time, the pressure also does not change, and the current pressure can be maintained.

[0137] In addition, it should be noted that when the eyelid hot compress device provided in this embodiment is started, the initial pressure of the airbag can be the minimum pressure threshold Fmin set in advance. For example, Fmin is 0.1 MPa.

[0138] 502 - 2. If ΔT4 ≠ 0 or ΔH1 ≠ 0, it means that the temperature or humidity has been adjusted. At this time, the target pressure will be determined according to Flid, the target temperature, and the target humidity.

[0139] For example, determine the change ratio = wT × SQRT{ΔT4 × ΔT4 / [(Tmax - Tmin) × ΔT5]} + wH × SQRT{ΔH1 × ΔH1 / [(Hmax - Hmin) × ΔH2]}.

[0140] Among them, wT is the temperature change coefficient, which characterizes the influence degree of temperature on pressure and is set in advance, such as wT = 0.5.

[0141] wH is the humidity change coefficient, which characterizes the influence degree of humidity on pressure and is set in advance, such as wH = 0.5.

[0142] Tmax is the maximum temperature threshold set in advance, Tmin is the minimum temperature threshold set in advance, Hmax is the maximum humidity threshold set in advance, and Hmin is the minimum humidity threshold set in advance.

[0143] ΔT5 is the fifth temperature difference. If ΔT4 > 0, then ΔT5 = Tmax - Tlid; if ΔT4 < 0, then ΔT5 = Tlid - Tmin.

[0144] ΔH2 is the second humidity difference. If ΔH1 > 0, then ΔH2 = Hmax - Hin; if ΔH1 < 0, then ΔH2 = Hin - Hmin.

[0145] SQRT{} is the square root function, min{} is the minimum function, and max{} is the maximum function.

[0146] (1) If the change ratio is 0, determine the target pressure as Flid.

[0147] It shows that although the temperature and / or humidity are adjusted, the combined effect on the melting effect of meibomian gland oil has not changed. Therefore, the pressure is not changed, that is, the target pressure is Flid.

[0148] (2) If the change ratio > 0, determine the target pressure as max{Flid×(1 - change ratio), Fmin}.

[0149] Considering the adjustment of temperature and / or humidity, its effect on the melting effect of meibomian gland oil is enhanced. Therefore, reducing the pressure can achieve the discharge of oil, but the minimum cannot be lower than Fmin. For example, Fmin is 0.1 MPa.

[0150] (3) If the change ratio < 0, determine the target pressure as min{Flid×(1 + change ratio), Fmax}.

[0151] Considering the adjustment of temperature and / or humidity, its effect on the melting effect of meibomian gland oil is weakened. Therefore, increasing the pressure is required to achieve the discharge of oil, but the maximum cannot be higher than Fmax. For example, Fmax is 5 MPa.

[0152] In addition, 4) The process of controlling the heating plate according to the target temperature, controlling the airbag according to the target pressure, and controlling the ultrasonic atomization sheet according to the target humidity is as follows: Control the heating plate to heat to the target temperature, control the pressure in the airbag to be the target pressure, and control the ultrasonic atomization sheet to make the humidity in the device internal environment be the target humidity.

[0153] In addition, to improve the intelligence, refer to Figure 3 , the eyelid hot compress device provided in this embodiment further includes a timer, and the eyelid hot compress device can be automatically shut down through the timer.

[0154] Among them, the initial value of the timer is 0.

[0155] The timer is connected to the control module.

[0156] The control module is further configured to control the timer to stop timing and adjust the timer to the initial value when Tlid < Tmin. When Tlid ≥ Tmin, control the timer to time. After the timing duration of the timer reaches the preset duration, control the hot compress working module to stop working, control the timer to stop timing, and adjust the timer to the initial value.

[0157] Among them, Tmin is the preset minimum temperature threshold.

[0158] Controlling the timer to time includes:

[0159] If the timer has currently stopped timing, control the timer to start timing.

[0160] If the timer has not currently stopped timing, control the timer to continue timing.

[0161] That is to say, whenever the eyelid temperature Tlid is not less than the preset minimum temperature threshold Tmin, if the timer is in the off state (i.e., stopped timing), then the timer will be started (i.e., control the timer to continue timing), and if the timer is in the timing state (i.e., the timer has not currently stopped timing), then it will continue to time. During this period, if the eyelid temperature Tlid is less than the preset minimum temperature threshold Tmin, it indicates that the current temperature does not meet the requirements, then the timing of the timer will be stopped and reset (i.e., control the timer to stop timing and adjust the timer to the initial value), so that the timer can reflect the duration of reaching the preset temperature this time. If this duration reaches the preset duration (such as 10 minutes), control the hot compress working module to stop working (i.e., stop the operation of the eyelid hot compress device), control the timer to stop timing, and adjust the timer to the initial value.

[0162] The eyelid hot compress device provided in this embodiment can help the discharge of meibomian gland oil by softening and squeezing the meibomian gland oil based on temperature, humidity, and pressure, thereby alleviating dry eye.
