Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0030] A fast venting diaphragm pump such as figure 1 , 2 As shown, it includes an upper cover body 1, a valve seat 2 and a valve plate 3, and the upper cover body 1 is provided with an air outlet 4, a pressure relief port 5, and a communication cavity 6 connecting the air outlet 4 and the pressure relief port 5, and the valve plate 3 It is located between the valve seat 2 and the upper cover body 1. When the upper cover body 1 and the valve seat 2 are closed, a communication cavity 6 is formed. The valve plate 3 is provided with a pressure relief air bag 7 for opening or closing the pressure relief port 5. The valve seat 2 is provided with an intake channel 8 for communicating with the pressure relief air bag 7 and a gas release channel 9 for discharging the gas in the pressure relief air bag 7 .
[0031] Such as figure 1 , 2 As shown, the lower end of t...

The invention discloses a diaphragm pump achieving rapid exhaust, and belongs to the technical field of diaphragm pumps. According to the technical scheme, the diaphragm pump is characterized in thatthe diaphragm pump comprises an upper cover body, a valve seat and a valve block; a gas outlet, a pressure relief opening and a communicating cavity communicating with the gas outlet and the pressurerelief opening are arranged on the upper cover body; the valve block is arranged between the valve seat and the upper cover body; the communicating cavity is formed when the upper cover body and the valve seat are combined in a covering manner; a pressure relief gas bag is arranged on the valve block; a gas inlet channel used for communicating with the pressure relief gas bag and a gas discharge channel used for discharging out gas in the pressure relief gas bag are arranged on the valve seat; a buffer seat is arranged at the lower end of the valve seat and provided with a buffer tank; when the buffer seat and the valve seat are combined in a covering manner, buffer space is formed by the lower surface of the valve seat and the buffer tank; and a supply channel used for communicating withthe buffer space and the gas inlet channel is arranged on the valve seat. According to the diaphragm pump, gas flow in the pressure relief gas bag can be prevented from fluctuating, and the stabilityof gas flow supply can be improved.
Description
technical field [0001] The invention belongs to the technical field of diaphragm pumps, and more specifically relates to a diaphragm pump for rapid exhaust. Background technique [0002] Diaphragm pumps are commonly used to provide compressed air to pressurized targets such as blood pressure monitors. Diaphragm pumps are pumps that deliver air to a pressurized target by partially deforming a diaphragm made of elastic material. [0003] At present, the Chinese patent with the notification number CN1288344C discloses a diaphragm pump, which includes at least one diaphragm part forming a pump chamber, a driving part arranged on the diaphragm part, a suction valve and a discharge valve communicating with the pump chamber , by moving the driving part up and down to play the role of a pump, characterized in that: at least one diaphragm part is connected to a diaphragm body by a flat part; a corresponding suction valve; and a plate-like discharge valve arranged in the approximate...
