[0023] Reference Figures 1 to 4A diaphragm pump for convenient automated production includes a pump body 100, a diaphragm component 200, and a sealing component 300. The pump body 100 is provided with an inlet channel 110, a pump chamber groove 120, an outlet chamber groove 130, and an outlet channel 140. The inlet channel 110 is connected to the pump chamber groove 120 via an inlet check valve 150, the pump chamber groove 120 is connected to the outlet chamber groove 130 via an outlet check valve 160, and the outlet channel 140 is connected to the outlet chamber groove 130. The diaphragm component 200 is disposed in the pump body 100 and covers the opening of the pump chamber groove 120, forming a pump chamber with the diaphragm component 200 and the pump chamber groove 120. The sealing component 300 is disposed in the pump body 100 and covers the opening of the outlet chamber groove 130, forming an outlet chamber with the sealing component 300 and the outlet chamber groove 130. The outlet cavity 130 is elongated, and the sealing member 300 is also elongated to fit the shape of the outlet cavity 130. The sealing member 300 includes a sealing section 310 and a tapered section 320 along its thickness direction. The circumferential surface of the sealing section 310 is a straight, unprotruding surface. The large end of the tapered section 320 connects to the sealing section 310. The sealing member 300 is inserted into the outlet cavity 130, and the sealing section 310 is used for sealing against the sidewall of the outlet cavity 130. In implementation, the thickness direction of the sealing member 300 is shown by double arrow B in the attached drawing.

[0024] The aforementioned diaphragm pump features a sealing component 300 composed of a sealing section 310 and a conical section 320. The sealing section 310 has a straight, non-protruding circumferential surface. The sealing component 300 is elongated and regularly shaped, facilitating automated feeding. Its straight surface also allows for easy clamping and positioning. The conical section 320 guides insertion into the outlet cavity 130, enabling automated equipment to easily install the sealing component 300 into the outlet cavity 130. The elongated structure of the sealing component 300, along with the straight-surfaced sealing section 310 and the guiding conical section 320, facilitates automated feeding, clamping, and installation.

[0025] In this embodiment, the sealing section 310 is provided with an outer end face, and the outer end face is provided with a disassembly auxiliary hole 330. When it is necessary to disassemble the sealing component 300, the sealing component 300 can be pried out of the air outlet groove 130 by inserting a pin into the disassembly auxiliary hole 330. This avoids prying the sealing component 300 out from the side wall of the air outlet groove 130, thus providing better protection for the pump body 100.

[0026] In this embodiment, the sealing member 300 is provided with disassembly auxiliary holes 330 at both its front and rear ends along its length. With this structure, the sealing member 300 can be pried out from both ends, thus facilitating operation.

[0027] In this embodiment, the sealing element 300 is an elastic element, and the sealing section 310 is interference-fitted with the side wall of the air outlet groove 130, thereby achieving a good sealing effect.

[0028] In this embodiment, the bottom of the air outlet groove 130 is provided with an air outlet hole 170 that communicates with the pump chamber groove 120. The air outlet one-way valve 160 is provided on the bottom side of the air outlet groove 130 and is used to control the air outlet hole 170 to send air to the air outlet groove 130 in one direction.

[0029] In this embodiment, the wall of the outlet chamber groove 130 is provided with a limiting rib 180, and the height of the limiting rib 180 relative to the bottom of the outlet chamber groove 130 is higher than the height of the outlet one-way valve 160 relative to the bottom of the outlet chamber groove 130. Using the above structure, the limiting rib 180 can be used to limit the sealing component 300 from over-installation, preventing it from contacting the one-way valve and affecting its structural function.

[0030] In this embodiment, the air outlets 170 are arranged in pairs. A mounting portion 190 is provided at the bottom of the air outlet groove 130 between the two paired air outlets 170. The one-way valve 160 includes a diaphragm 161 and a fixing member 162. The diaphragm 161 is disposed at the bottom of the air outlet groove 130, with its two sides respectively covering the two paired air outlets 170. The fixing member 162 is fixed to the mounting portion 190 and presses the middle part of the diaphragm 161 against the bottom of the air outlet groove 130. When the pump chamber supplies air to the air outlet chamber, the output airflow from the pump chamber can rush out from the air outlets 170 and push open the diaphragm 161 to enter the air outlet chamber. Conversely, the reverse airflow will press the diaphragm 161 against the bottom of the air outlet groove 130, preventing it from entering the pump chamber, thus achieving the function of a one-way valve. The one-way valve structure is formed by covering the two pairs of vent holes 170 on both sides of the diaphragm 161 fixed in the middle. The structure is simple and easy to implement.

[0031] In this embodiment, the mounting portion 190 is a plug-in post, the middle part of the diaphragm 161 is sleeved on the mounting portion 190, and the fixing member 162 is a plug with a sleeve hole and is sleeved on the mounting portion 190. Using the above structure, fixing is simple and assembly is easy.

[0032] In this embodiment, positioning portions 1611 extend from both sides of the middle portion of the diaphragm 161, and positioning grooves 131 corresponding to the positioning portions 1611 are respectively provided on both sides of the bottom of the air outlet groove 130. The positioning portions 1611 are inserted into the corresponding positioning grooves 131. With the above structure, the position of the diaphragm 161 can be positioned, thereby making the installation position more stable.

[0033] It is conceivable that the exhaust check valve 160 is not limited to the above-described implementation. In this art, there are many implementations of check valve structures, and those skilled in the art can configure them according to actual conditions; these will not be elaborated upon here. In this embodiment, the structure of the intake check valve 150 is similar to that of the exhaust check valve 160, and the intake check valve 150 can be specifically implemented with reference to the implementation of the exhaust check valve 160.

[0034] In this embodiment, the pump body 100 is connected to a base 400, and the base 400 is connected to a cover 500. The cover 500 and the base 400 together form an inner cavity. The pump body 100 is disposed within the inner cavity. The base 400 has an air inlet, which communicates with the air inlet channel 110 through the inner cavity. The air inlet is covered with a filter element. Using this structure, the incoming air can be filtered, resulting in good air quality. In this embodiment, the filter element can be a sponge or other structure capable of filtering gas.

[0035] In this embodiment, a pump drive mechanism 600 for driving the deformation of the diaphragm 200 is disposed in the aforementioned inner cavity. It includes an electromagnet 610 and a swing arm 620. One end of the swing arm 620 is hinged to the base 400, and the other end is opposite to the magnetic pole of the electromagnet 610. A magnet is disposed at the other end of the swing arm 620, and the middle portion of the swing arm 620 is fixed to the diaphragm 200. When an alternating current is applied to the electromagnet 610, the magnetic field changes, and the magnet drives the other end of the swing arm 620 to swing, thereby causing the diaphragm 200 to deform.

[0036] In this embodiment, the diaphragm 200 is sleeved and fixed to the pump body 100, and the middle part of the diaphragm 200 is fixed to the middle part of the swing arm 620 by threaded fasteners.

[0037] In this embodiment, two sets of pump chamber grooves 120 and diaphragm members 200 are provided respectively, and two swing arms 620 are also provided respectively.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
