Two hot compress soft bags 210 are located in the housing 240, and the hot compress soft bag 210 is used for contact hot compress on the patient's eyes. The hot compress bag moving plate 250 is fixed to the side of the hot compress soft bag 210 facing away from the patient's eyes. The pushing component 220 is used to push the hot compress bag moving plate 250 away from / close to the patient's eyes to make the hot compress soft bag 210 contact the patient's eyes.

[0046] Both ends of the headband 100 are fixedly connected to the outer surface of the housing 240 of the hot compresser 200, and the headband 100 is used to wear the hot compresser 200 on the patient's eyes.

[0047] The constant temperature hot water device 300 is used to heat water to a set temperature.

[0048] The circulating water component 400 forms a circulating water path between the water tank of the constant temperature hot water device 300 and the hot compress soft bag 210 of the hot compresser 200. The hot water in the water tank of the constant temperature hot water device 300 flows through the hot compress soft bag 210 of the hot compresser 200 and finally returns to the water tank of the constant temperature hot water device 300 to keep the constant temperature hot water device 300 maintaining the water temperature all the time.

The water pump 410 always conveys the water in the water tank of the constant temperature hot water device 300 to the hot compress soft bag 210. At the same time, part of the water in the hot compress soft bag 210 flows back to the water tank of the constant temperature hot water device 300.

[0051] Further, the pushing component 220 includes a guiding component 221, a gas source cylinder 222, and a linear driving component 223;

[0052] The guiding component 221 includes a telescopic rod 2211 and an actuating cylinder 2212; wherein, the side of the hot compress bag moving plate 250 away from the hot compress soft bag 210 is fixed to the first end of the telescopic rod 2211 and fixed to the moving end (i.e., the actuating end of its piston rod) of the actuating cylinder 2212, and the other ends of the telescopic rod 2211 and the actuating cylinder 2212 are fixedly arranged in the housing 240.

[0054] The rodless cavity of the gas source housing 2221 of the gas source cylinder 222 is communicated with the rodless cavity of the actuating cylinder 2212 in the guiding component 221 through a pipeline; the movement of the piston rod 2223 of the gas source cylinder 222 allows the gas in the rodless cavity of the gas source cylinder 222 to enter / exit the rodless cavity of the actuating cylinder 2212, enabling the piston rod of the actuating cylinder 2212 in the guiding component 221 to drive the hot compress bag moving plate 250 to approach / leave the patient's eyes.

[0068] The controller is electrically connected to the bending sensor 22355 and is used to obtain the signal of the bending of the elastic longitudinal beam 22354 through the bending sensor 22355; the controller is electrically connected to the motor 2231;

[0069] When the controller obtains the signal of the bending of the elastic longitudinal beam 22354, the controller controls the motor 2231 to stop rotating.

[0070] Working principle description:

[0071] After the user wears the eye hot compress device, the motor 2231 is started to rotate forward. The motor 2231 drives the screw rod 2232 to rotate, causing the moving nut 2236 threadedly connected thereto to perform a linear motion. The moving nut 2236 drives the piston rod 2223 of the air source cylinder 222 to move linearly through the connecting member 2233, the slider 2234 and the connecting assembly 2235, so that the gas in the rodless cavity of the air source cylinder 222 enters the rodless cavity of the actuator cylinder 2212 of the guiding assembly 221, pushing the piston rod of the actuator cylinder 2212 to extend, driving the hot compress bag moving plate 250 to move, and making the hot compress soft bag 210 directly contact the user's eyes.

[0072] Since there are differences in the head shapes and eye socket depths of different users, in order to ensure that the hot compress soft bag 210 exerts the same pressure on the eyes, the moving distance of the hot compress soft bag 210 needs to be adjusted accordingly. The present invention determines whether the hot compress soft bag 210 has moved in place based on the set pressure applied to the eyes. The specific principle is as follows: When the pressure of the hot compress soft bag 210 on the eyes reaches the set threshold pressure, the gas pressure in the actuator cylinder 2212 is a determined value, and the gas pressure in the air source cylinder 222 is also determined accordingly. At this time, the reaction force received by the connecting assembly 2235 from the piston rod 2223 of the air source cylinder 222 is determined, the compression amount of the spring 22353 is unique, the connecting seats 22351 approach each other, and the outward expansion of the rotating joints of the two rotating rods 22352 abuts against the elastic longitudinal beam 22354, causing the elastic longitudinal beam 22354 to undergo a bending deformation. After the bending sensor 22355 detects the bending of the elastic longitudinal beam 22354, it transmits a signal to the controller, and the controller controls the motor 2231 to stop rotating, thereby achieving the effect of the hot compress soft bag 210 exerting the same pressure on the user's eyes.

[0073] Further, it further includes an infrared sensor, the infrared sensor is fixed inside the housing, and the infrared sensor is electrically connected to the controller;

[0074] When the hot compresser 200 covers the user's eyes, the detection end of the infrared sensor faces the user's head, and the controller drives the motor to rotate forward to make the hot compress bag contact the user's eyes; when the hot compresser 200 is removed from the user's eyes and the detection end of the infrared sensor no longer detects the head, the controller drives the motor to rotate in reverse, and the hot compress bag returns to the initial position.

[0075] Further, the motor is a servo motor.

[0076] The above are only the preferred embodiments of the present invention for patents, and are not intended to limit the present invention for patents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention for patents shall be included within the protection scope of the present invention for patents.
