Description

このような課題を解決するために、本発明の電磁式ダイヤフラムポンプは、電磁石と、電磁石の極性変化に伴い振動する振動子と、振動子の端部に配置されるダイヤフラムと、ダイヤフラムの周縁部を挟持して固定することができるダイヤフラム台およびダイヤフラム保持部と、前記振動子を覆う振動子カバーを有し、一対の前記ダイヤフラム台と一対の前記ダイヤフラムとによって、ダイヤフラムより内側に一対の内隔室が形成され、当該一対の内隔室を連通させるように、前記ダイヤフラム台とは別体の振動子カバーが取り付けられ、前記ダイヤフラム台は、ダイヤフラムの周縁部を挟持する作用をする挟持基部と、振動子の端部分を通過させる開口部と、当該開口部の外周部に形成され、前記振動子カバーの端部を振動子カバーパッキンとともに収納する収納部と、を有するように構成される。 In order to solve such problems, an electromagnetic diaphragm pump according to the present invention includes an electromagnet, a vibrator that vibrates with a change in polarity of the electromagnet, a diaphragm disposed at an end of the vibrator, and a peripheral portion of the diaphragm. A diaphragm base and a diaphragm holding portion that can be sandwiched and fixed, and a vibrator cover that covers the vibrator, and a pair of diaphragms inside the diaphragm by the pair of diaphragm base and the pair of diaphragms. A chamber cover is formed, and a vibrator cover separate from the diaphragm base is attached so that the pair of inner compartments communicate with each other, and the diaphragm base includes a sandwiching base portion that acts to sandwich the peripheral portion of the diaphragm. An opening for passing the end portion of the vibrator, and an outer peripheral portion of the opening. Configured to have a housing section for housing with.

このように振動子カバー１００と接合されるダイヤフラム台５０は、ダイヤフラム４０の周縁部を挟持する作用をする挟持基部５１と、振動子３０の端部分を通過させる開口部５３と、この開口部５３の外周部に形成され、振動子カバー１００の端部を振動子カバーパッキン１５５とともに収納する収納部を有する。 As described above, the diaphragm base 50 joined to the vibrator cover 100 includes a sandwiching base 51 that serves to sandwich the peripheral edge of the diaphragm 40, an opening 53 that allows the end portion of the vibrator 30 to pass through, and the opening 53. And a housing portion that houses the end portion of the vibrator cover 100 together with the vibrator cover packing 155.
