The detailed description of the figure is as follows. The first figure is a top perspective view of the present invention. The second figure is a bottom perspective view of the present invention. The third figure is a top view of the present invention in which a partial cross-section is made in the portion of the flow path. Φ Φ The fourth picture is a cross-sectional view of the 4-4 line. The fifth picture is a scratch view of the 5-5 line. The sixth picture is a cross-sectional view of the 6-6 line. Figure 7 is a cross-sectional view of the bottom surface of the present invention. As shown in the figure, the electronic pressure controlled breast pump of the present invention comprises: / body 10, the body is provided with an intake flow passage 11, a conversion flow passage 12, and an air flow passage 13 'the intake air passage 11 and the The air flow passages 13 are respectively communicated with the conversion flow passages 12 through the through holes 14, 15 respectively. The conversion flow passages are provided with a grassward valve plate 16 at the through hole 14 communicating with the intake air flow passages 11, The unidirectional entry into the conversion flow passage 12 by the intake passage 11 is reversed. The through-air passage 13 of the outlet air passage 13 and the switching passage 12 also bites the check valve 17' so that the gas can be unidirectionally discharged from the flow passage 13 by the switching passage 12, and the reverse is reversed. One side of the conversion flow path 12 is provided with an entry w / film 18 as shown in the fourth to sixth figures. / is up to 20, is disposed on the side of the body 1 , the mandrel 21 of the motor has an eccentric shaft 22, the eccentric shaft is sounded on a linkage rod 23, and the other end of the linkage rod 23 is The film 18 is applied. The moving movement of the 忒 linkage rod 2 3 by the motor 2 可以 can cause the film 18 to move up and down in the conversion flow path 12, and can be squeezed when the film 18 is inserted into the conversion flow path Η The gas in the conversion flow path 12 enters the outlet air flow path 13, and when the film 18 is restored, the gas in the intake flow path 11 is drawn into the conversion flow path 12 as shown in the second figure. A manual pressure adjustment group 3 is disposed in the body 1 〇 and communicates with the air intake & flow passage 11 . The manual pressure adjustment group 30 includes a knob 31 for providing a user to manually adjust the suction force, and one can be used. The quick release of the pressure relief button 32, as shown in the seventh figure. A control circuit 40 is connected to the motor 20 and an electronic pressure adjustment button 41. The electronic pressure adjustment button 41 is a variable resistor for controlling the rotation speed of the motor 20, and can be calculated by the control circuit 40. It is known that the rotational speed corresponds to the pressure value as shown in the first figure. The control circuit 40 does not necessarily have to be provided with the electronic pressure adjustment knob 41, and the pressure value can be directly set in the control circuit 40 in advance, and the same effect can be produced when the control circuit 40 is executed. a pressure sensor 50 is connected to the control circuit 40 for sensing a gas vacuum value in the inlet passage '. The pressure sensor 50 is disposed in a manifold 51, and the manifold 51 is disposed on the pressure sensor 50. The body is also in communication with the intake runner 11 such that the pressure value in the manifold 51 can be the same as the pressure value in the inlet runner 11. An electromagnetic 阙 60 is disposed in the body 1 〇 and communicates with the intake runner 11 , and the solenoid valve 60 is coupled to the control circuit 40 to provide a quick pressure relief function of the electronic model 5 201028183 . A switch 70 is disposed on the body 1 〇 and connected to the control circuit 4 , to activate or deactivate the entire circuit. A power source 80, coupled to the motor 20 and the control circuit 40, is used to provide the control circuit 40 and the electrical power required to operate the motor. In the present embodiment, the power source is a battery pack disposed on the side of the body 1 and connected to the motor 20 and the control circuit 40 for providing the control circuit 40 and the power required for the motor 20 to operate. The power source 80 can also be an external source of electrical power. In addition to the configuration of the present invention, the suction force required by the user can be adjusted by the general manual pressure adjustment group 30. The strength of the suction can also be adjusted by rotating the electronic pressure adjustment knob 41. When the user sets the required motor 20 rotation speed by the electronic pressure adjustment button 41, it is equal to the vacuum pressure value of the suction of the breast pump. The pressure sensor 50 senses the intake air flow passage 11 The internal air pressure value is transmitted to the control circuit 40. At this time, if the suction value is greater than the set value, the control circuit 40 lowers the output power of the motor 20 to reduce the suction force. Conversely, if the suction value is less than the set value, the control circuit 40 will Increasing the wheeling power of the motor 20 to increase the suction force, thereby achieving the purpose of electronically controlling the suction force. Such an automatic adjustment function is particularly effective when the user starts using it and when it is stopped, because in the two At the time point, the pressure value in the intake runner 11 changes the most, and the conventional manual/electric breast pump adjusted product cannot automatically adjust the change of the pressure value, and the product emphasizes the automatic control of the vacuum pressure. In order to let breastfeeding mother 6 201028183 mother can use this product more comfortable, and will not be mechanized, more close to humanization and product design. In addition, the pressure sensor 50 can further transmit a signal to the control circuit 40 when the pressure value is abnormal, for example, when the pressure value in the intake runner 11 is abnormally increased, so that the motor 20 can be stopped urgently to avoid the user. The damage caused by the use is not achievable by the traditional manual breast pump. Compared with the conventional manual/electric adjustment method, the present invention can quickly and easily adjust the suction strength of the user and improve the inconvenience of the conventional product. 201028183 [Simplified description of the drawings] The first figure is a top perspective view of the present invention.
