The T-shape referred to herein means a T-shape in cross section along the axial direction.
In order to facilitate pushing the T-shaped plug 122 upward, a push plate 1221 is disposed at the bottom of the small diameter end of the T-shaped plug 122, and in use, the push plate 1221 is disposed at the large diameter end of the T-shaped tube 123, and the outer peripheral wall of the push plate 1221 is bonded and sealed with the inner peripheral wall of the large diameter end of the T-shaped tube 123. So configured, the gas in the upper chamber 1129 is prevented from entering the humidifier 31 through the gas exchange flow channel and T-tube 123 when the elastic membrane 1123 is sprung up.
It should be noted that the diameter of the push plate 1221 is larger than the diameter of the small diameter end of the T-shaped plug 122, thereby increasing the contact area between the water vapor and the T-shaped plug 122 and increasing the sensitivity of the reaction of the stability control assembly 120.
In order to limit the T-shaped plug 122, the T-shaped plug 122 is prevented from sliding away from the adjusting hole, the top end of the control box 121 is provided with a limit cylinder 125, the top end of the limit cylinder 125 is provided with a top plate, the side wall of the limit cylinder 125 is provided with air holes (not shown in the figure) for ventilation between the limit cylinder 125 and the outside when the T-shaped plug 122 moves up and down, the bottom end of the limit cylinder 125 is in an opening shape, the limit cylinder 125 is communicated with the adjusting hole, a limit flange 1251 is arranged on the peripheral wall of the top part close to the large-diameter end of the T-shaped plug 122, a coil spring 1252 is accommodated in the limit cylinder 125, the top end of the coil spring 1252 is abutted to the top plate of the limit cylinder 125, the top part of the large-diameter end of the T-shaped plug 122 is inserted into the limit cylinder 125 and is simultaneously inserted into the coil spring 1252, the bottom end of the coil spring 1252 is abutted to the limit flange 1251, the T-shaped plug 122 can slide relative to the limit cylinder 125, and when the T-shaped plug 122 moves up, the limit flange 1251 compresses the coil spring 1252, and the coil spring 1252 is in a compressed state.
It should be noted that, the inner diameter of the small diameter end of the T-shaped pipe 123 is smaller than the inner diameter of the connecting pipe 111, and the inner diameter of the small diameter end of the T-shaped pipe 123 may be 1/5 to 1/3, for example, 1/4 and 1/5 of the inner diameter of the connecting pipe 111.
In use, the opening pressure of the stability control assembly 120 is smaller than the opening pressure of the gas collection assembly 110, the stability control assembly 120 can be opened with only a smaller vapor pressure, and the opening of the adjustment opening can be adaptively adjusted according to the vapor pressure, so as to control the smooth operation of the slider 1122.
In use, after the three on-off valves 315 are closed, the solenoid valve 1111 is opened, water vapor in the humidifier 31 flows into the T-pipe 123 and the collection tank 1121 through the connection pipe 111, respectively, and the gas collection assembly 110 starts to operate.
Specifically, when the water vapor pressure is small, the water vapor upper push plate 1221 and the push plate 1221 push the T-shaped plug 122 to slide upward, so that the small diameter end of the T-shaped plug 122 slides at least partially to the junction between the adjustment hole and the internal cavity of the control box 121, the adjustment port is opened, the gas exchange flow passage of the upper chamber 1129 of the collection box 1121 is opened, and at this time, the adjustment port is opened with a small amplitude. When the pressure of the water vapor is gradually increased, the water vapor pushes up the sliding part 1122, and at the moment, the elastic membrane 1123 is sprung upwards, so that the gas in the upper chamber 1129 of the collecting tank 1121 is discharged from the gas exchange circulation channel, and when the sliding part 1122 is pushed out of the communication hole 1125, the water vapor enters the auxiliary tank 1131 through the communication hole 1125 to be condensed and recovered, namely, the water vapor is liquefied into small water droplets by encountering the inclined plate 1132, and the small water droplets flow into the humidifier 31 sequentially through the water outlet pipe 1133 and the connecting pipe 111 by the drain valve; when the water vapor gradually decreases, the slider 1122 moves downward, during which the elastic diaphragm 1123 gradually rebounds, and the opening degree of the adjustment port formed between the outer circumferential wall of the small diameter end of the T-shaped plug 122 and the inner circumferential wall of the adjustment hole gradually decreases due to the decrease in the water vapor pressure, so that the downward moving speed of the slider 1122 gradually slows down, thereby effectively controlling the smooth operation of the slider 1122, preventing the upward and downward irregular vibration channeling of the slider 1122 during the movement, and the chattering vibration.
Wherein, the stability control component 120 is turned on before the gas collection component 110, and is turned off later than the gas collection component 110, and when the water vapor pressure in the humidifier 31 is smaller than the third preset air pressure value, the stability control component 120 is turned off, and the gas collection component 110 is in a reset state; when the slider 1122 is in the reset state, the slider 1122 is stopped by the support of the elastic member 1124 and closes the communication hole 1125 in the collection box 1121.
