Description

Technical Field

[0001] This utility model belongs to the field of pump body technology, and specifically relates to a novel pump body structure. Background Technology

[0002] One existing pump body structure is connected by three evenly distributed claw clips within a circle. Its structure is simple, eliminating complex processes like screw fixing and reducing production costs. However, it also has the following drawbacks: to ensure the strength and effectiveness of the claw clips, the positioning bosses of the claw clips must be of a certain width, the claw clips themselves must be thick enough, and the positioning step connecting and fixing the claw clips must also have a certain height, achieving the required strength to ensure the stability of the connection. To meet these requirements, the designed structure requires the claw clips to undergo a certain deformation to fit into the groove of the positioning step. Only when the deformation is sufficient for the claw clips to fully retract into the positioning step groove can they be installed in their fixed position. This is very laborious and difficult. Furthermore, its movement mechanism is achieved through a push-pull structure formed by a return spring connected to the tail of the movable iron core. In this structure, the return spring is in a compressed state, and the fixing method of the fixed iron core is also a movable structure. Therefore, under the action of the return spring, the iron core will be in a non-central axis state, with a certain degree of inclination. The force is precisely at the inclined end of the iron core. The force range of the return spring includes the entire space between the iron core and the return spring. In this state, during the reciprocating motion of the movable iron core, the eccentric force of the return spring causes significant polarization of the iron core. This results in greater friction between the iron core and the inner wall of the cylindrical tube, thus increasing the power loss of the pump. This is detrimental to the stability of the pump flow rate, leading to greater attenuation.

[0003] Therefore, this utility model designs a novel pump body structure. Utility Model Content

[0004] The purpose of this invention is to provide a novel pump body structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel pump body structure, comprising a coil assembly, a fixed base at the top of the coil assembly, a cylindrical tube extending from the bottom of the fixed base, the cylindrical tube penetrating the center of the coil assembly and engaging with the bottom of the coil assembly for positioning, a locking cover at the top of the fixed base, an outlet and an inlet respectively at the top of the locking cover, a valve switching assembly capable of alternately communicating with the outlet and inlet between the fixed base and the locking cover, and multiple valves evenly distributed around the perimeter of the locking cover. Each claw buckle has a locking groove on the fixed base that engages with the claw buckle. The top of the locking groove extends upward above the top surface of the fixed base, and the claw buckle engages with the locking groove. A flexible iron core assembly capable of driving the valve switching component is installed inside the cylindrical tube. The flexible iron core assembly includes a movable iron core movably disposed inside the cylindrical tube, and a return spring entirely sleeved on the movable iron core. The upper fixed end of the return spring is connected to a spring fixing step on the movable iron core, and the bottom end of the return spring is connected to an internal spring fixing step inside the cylindrical tube.

[0006] Preferably, the valve connection switching assembly includes a valve cover disposed between the lock cover and the fixed seat. The valve cover is provided with an inlet channel communicating with the inlet, and the valve cover is also provided with an outlet channel communicating with the outlet. The inlet channel and the outlet channel are interconnected, and a switchable diaphragm is provided at the connection between the inlet channel and the outlet channel. The bottom of the diaphragm is connected to the top of the movable iron core, and the movable iron core drives the diaphragm to perform up-and-down reciprocating deformation motion.

[0007] Preferably, the valve connection switching assembly further includes a duckbill valve B disposed in the water inlet channel and a duckbill valve A disposed in the water outlet channel, wherein both duckbill valve A and duckbill valve B are one-way valves.

[0008] Preferably, a damping ring is provided at the lower end of the movable iron core, the tail of the movable iron core extends into the cylindrical tube, and the tail of the movable iron core is lower than the spring fixing step inside the cylindrical tube; an annular embedding groove matching the damping ring is provided on the outer surface of the movable iron core, and the damping ring is embedded in the annular embedding groove.

[0009] Preferably, the locking groove, the fixing seat, and the cylindrical tube are integrally formed into a single structure.

[0010] Preferably, the water outlet, water inlet, lock cover, and claw buckle are all integrally formed one-piece structures.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By raising the top of the fixing base and designing the locking groove, the entire locking groove is higher than the top surface of the fixing base, making the claw buckle easier and faster to assemble during installation.

[0013] By fitting the entire return spring onto the movable iron core, the restoring force of the return spring acts only on the upper middle part of the movable iron core, and the restoring force of the return spring is in a balanced state. Even if the return spring is eccentric, the force it experiences will be smaller, with only its own weight and no compressive restoring force. This reduces the polarization of the movable iron core and decreases the friction between the movable iron core and the inner wall of the cylindrical tube, thereby reducing the power loss of the pump body.
