Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump technology, specifically a gas-liquid hybrid diaphragm pump. Background Technology

[0002] The gas-liquid hybrid diaphragm pump is a new type of diaphragm pump that combines pneumatic and hydraulic drive principles. It uses a gas-liquid hybrid power source to drive the diaphragm in reciprocating motion, achieving fluid intake and discharge. Its core structure includes a gas-liquid conversion unit (such as a gas-liquid cylinder or accumulator), an elastic diaphragm assembly, and a check valve group: pneumatic pressure drives the hydraulic medium to generate power, which in turn deforms the diaphragm, changing the pump chamber volume, and works with the check valve to complete the medium delivery.

[0003] Small diaphragm pumps have soft tubing connected to their inlet and outlet ends for water delivery. However, the tubing is close to friction limiters at the inlet and outlet ends, and the water pressure in gas-liquid hybrid diaphragm pumps is relatively high, which can easily cause the tubing to detach from the inlet and outlet ends. Therefore, there is an urgent need for a gas-liquid hybrid diaphragm pump to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a gas-liquid hybrid diaphragm pump to solve the problem mentioned in the background art that the inlet and outlet ends of the small diaphragm pump are connected to soft pipes for water transportation. However, the hose and the inlet and outlet ends are close to the friction limit, and the water pressure of the gas-liquid hybrid diaphragm pump is relatively large, which makes it easy for the hose to fall off from the inlet and outlet ends.

[0005] This utility model provides the following technical solution: a gas-liquid hybrid diaphragm pump, including a pump body mechanism, wherein the pump body mechanism includes a main body of the equipment and two water inlet / outlet ends for water liquid entry and exit;

[0006] It also includes a fastening mechanism, which includes fasteners that encircle the hose and the water outlet end;

[0007] The fastener is divided into two unconnected parts that are fixed by bolts and nuts.

[0008] To achieve the above technical solution, fasteners are positioned in a ring shape around the water outlet and the outside of the hose. Nuts and screws are used to lock and limit the fasteners, thereby clamping the water outlet and the hose. Compared with the prior art, this device improves the fixing strength between the water outlet and the hose, making the hose less likely to fall off the water outlet.

[0009] As a further improvement to this utility model, a bent mounting bracket is connected to the outer shell of the main body of the device, and mounting holes are provided on both the horizontal and vertical surfaces of the mounting bracket.

[0010] The above technical solution improves the installation angle of the main body of the equipment and enhances its applicability.

[0011] As a further improvement to this utility model, the outer shell of the main body of the device is provided with a mark corresponding to the water flow direction of the water outlet.

[0012] The above technical solution makes it easier for users to distinguish the water supply end.

[0013] As a further improvement to this utility model, the upper and lower halves of the two fasteners are connected by two connecting members, and the screw and nut are fixed on the connecting members.

[0014] The above technical solution facilitates the simultaneous clamping and limiting of two water outlets and hoses.

[0015] As a further improvement to this utility model, the pressing surface of the fastener is uniformly connected with anti-slip strips.

[0016] The above technical solution improves the friction effect between the fastener extrusion surface and the hose surface.

[0017] As a further improvement to this utility model, a reinforcing member is provided at the connection between the fastener and the connecting member, and the reinforcing member, the fastener and the connecting member are an integral component.

[0018] The above technical solutions improve the overall strength of fasteners and connecting parts.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. This utility model uses fasteners that are positioned in a ring shape around the water outlet and the outside of the hose. Nuts and screws are used to lock and limit the fasteners, thereby clamping the water outlet and the hose.

[0021] 2. Compared with the prior art, this utility model improves the fixing strength between the water outlet end and the hose, making the hose less likely to fall off the water outlet end. Attached Figure Description
