The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 3, the present embodiment provides a pump body structure, which includes a pump body 1, a check valve 2 and a joint 3, wherein a first annular step 111 is disposed in a liquid outlet pipe 11 of the pump body 1, and the check valve 2 is disposed in the liquid outlet pipe 11. Check valve 2 includes valve body 21 and valve plug 22, and valve plug 22 can support to press or break away from first annular step 111, connects 3 can dismantle to be connected in drain pipe 11 and can be at the spacing valve body 21 of the axial of drain pipe 11.

Through setting up first annular step 111 and joint 3, compact structure can realize spacing the installation of check valve 2. And because connect 3 can dismantle and connect drain pipe 11, the installation and the dismantlement of check valve 2 of being convenient for.

As shown in fig. 1, one of the joint 3 and the liquid outlet pipe 11 is provided with an external thread, and the other is provided with an internal thread capable of mating with the external thread. Specifically, in this embodiment, the connector 3 is provided with an external thread, and the liquid outlet pipe 11 is provided with an internal thread, but in other embodiments, the liquid outlet pipe 11 may also be provided with an external thread, and the connector 3 may also be provided with an internal thread.

Referring to fig. 1 and 2, the check valve 2 further includes an elastic member 23, one end of the elastic member 23 abuts against the valve body 21, and the other end of the elastic member 23 abuts against the valve plug 22, and the elastic member 23 can push the valve plug 22 to abut against the first annular step 111.

It will be appreciated that when the liquid medium is discharged outwardly from the outlet pipe 11, the elastic member 23 is compressed under the pressure of the liquid medium so that the valve plug 22 is disengaged from the first annular step 111, and the liquid medium is discharged. When the liquid outlet pipe 11 stops discharging the liquid medium outwards, the valve plug 22 is pressed against the first annular step 111 by the acting force of the elastic member 23, so as to close the liquid outlet pipe 11 and prevent the liquid medium from flowing back.

As shown in fig. 2, in the present embodiment, the valve plug 22 includes a conical plug and a connecting column connected to the valve body 21, and the elastic member 23 is sleeved on the connecting column and abuts against the conical plug. The material of above-mentioned toper stopper and spliced pole is flexible material (for example rubber), can produce deformation.

As shown in fig. 2, in this embodiment, the valve body 21 includes a plurality of supports 211 arranged at intervals along the circumferential direction of the liquid outlet pipe 11, a plurality of clamping grooves 112 extending along the axial direction of the liquid outlet pipe 11 are formed on the inner wall of the liquid outlet pipe 11, and the supports 211 can extend into the clamping grooves 112 and limit the clamping grooves 112.

Further, referring to fig. 3, a second annular step 113 is disposed in the liquid outlet pipe 11, the second annular step 113 is close to the water outlet of the liquid outlet pipe 11 relative to the first annular step 111, one end of the clamping groove 112 penetrates through the second annular step 113, and the second annular step 113 is used for limiting the connector 3.

It can be understood that, when installing the check valve 2, inserting each bracket 211 into the corresponding slot 112 makes the valve plug 22 press against the first annular step 111, and then installing the joint 3 to limit the valve body 21, so as to implement installation of the check valve 2, and the installation operation is simple.

Referring again to fig. 2, the check valve 2 further includes a sealing ring 24, and the sealing ring 24 is disposed on the valve plug 22. By providing the sealing ring 24, the sealing effect of the check valve 2 is further improved, and the backflow of the liquid medium is avoided.

As shown in figures 1 and 3, the pump body structure further comprises a pressure detector 4, and the pressure detector 4 is arranged on the liquid outlet pipe 11. Specifically, in the present embodiment, the pressure detector 4 is located between the first annular step 111 and the second annular step 113. By providing the pressure detector 4, the pressure in the liquid pipe 11 can be detected in real time.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
