Description

Technical Field

[0001] This utility model relates to the field of air pumps, and in particular to a detachable built-in pump for filling and pumping. Background Technology

[0002] An air pump is a device that uses a motor to drive a fan, which in turn moves air in a specific direction to inflate the product. Air mattresses, inflatable boats, and other inflatable products all require a dedicated air pump for inflation.

[0003] However, existing air pumps can only be used with connectors and cannot be used independently to inflate products with only a separate air inlet, resulting in poor compatibility. Furthermore, existing air pumps adjust their internal airflow structure and function by rotating a knob, but this method involves too many moving parts and is prone to malfunction after prolonged use. Therefore, to solve the above technical problems, this application proposes a detachable built-in pump for inflation / deflation. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a detachable built-in pump for filling and pumping.

[0005] The purpose of this utility model is achieved through the following technical solution: a removable built-in pump for filling and pumping, including a housing, a cover and a pump core, wherein the cover is rotatably connected to the housing, a mounting baffle is provided in the cavity of the housing, an elastic abutment component is provided on the mounting baffle, an air inlet and outlet hole is provided at one end of the housing, and a sealing component is provided in the air inlet and outlet hole.

[0006] When inflating, the pump core is placed in the cavity of the housing, the elastic abutment component abuts and pushes the air inlet end of the pump core and aligns the air outlet end of the pump core with the air inlet and outlet holes. When the pump core is in working condition, the gas pushes open the sealing component and blows out from the air inlet and outlet holes.

[0007] When pumping air, the pump core is reversed and placed into the cavity of the receiving shell. The elastic abutment component pushes against the outlet end of the pump core and causes the inlet end of the pump core to open the sealing component. The inlet and outlet holes are opened. When the pump core is in working condition, gas enters the pump core through the inlet and outlet holes and is discharged from the outlet end of the pump core.

[0008] As an improvement of the detachable built-in pump of this utility model, the elastic abutment component includes an abutment cover and an abutment spring. One end of the abutment spring abuts against one end of the abutment cover and the other end abuts against the cavity sidewall of the housing. The edge of the abutment cover is provided with a retaining edge, and the abutment cover passes through the mounting hole of the mounting baffle.

[0009] As an improvement of the present invention, the pump core is provided with an air inlet screen at the air inlet end and a plug-in pipe at the air outlet end of the pump core.

[0010] During inflation, the connecting pipe can be inserted into the air inlet and outlet holes, and the top cover abuts against the air inlet mesh cover;

[0011] During air extraction, the top cover abuts against the insertion pipe, and the air inlet mesh abuts against the sealing assembly.

[0012] As an improvement of the detachable built-in pump of this utility model, the sealing assembly includes a bracket, one end of which is provided with a sealing plate, and the other end of which is inserted into the air inlet and outlet holes; when inflated, the air pressure of the blown gas can deform the sealing plate, and the gas can be blown out from the gap between the sealing plate and the air inlet and outlet holes.

[0013] The end of the bracket that is inserted into the air inlet / outlet is provided with a notch and a limiting edge.

[0014] As an improvement of the present invention, the pump core includes a pump housing, which contains a motor mounting cavity, a battery mounting cavity, and a fan mounting cavity. The motor mounting cavity contains a motor and a PCB board, the battery mounting cavity contains a battery, and the fan mounting cavity contains a fan. The output shaft of the motor is connected to the fan. The PCB board has a switch that extends from the outside of the pump housing. The motor mounting cavity and the fan mounting cavity are connected. The air inlet of the pump core is connected to the fan mounting cavity, and the air outlet of the pump core is connected to the motor mounting cavity.

[0015] As an improvement of the present invention, the detachable built-in pump for filling and pumping, the opening edge of the receiving shell is provided with a connecting seat, the connecting seat is connected to the shell cover by a shaft pin, the free end of the shell cover is provided with a buckle hole, the upper end of the mounting baffle is provided with a buckle plate, and one side of the buckle plate is provided with a limiting baffle plate.

[0016] When the cover is placed over the opening of the housing, the snap plate extends into the snap hole, and the limiting baffle restricts the opening of the cover.

[0017] As an improvement to the removable built-in pump of this utility model, the inner side of the housing cover is provided with a stop block, which corresponds to the switch. When the housing cover is placed over the opening of the housing, the stop block presses the switch, and the switch is in the closed state. Closing the housing cover shuts off the pump core's operation.

[0018] As an improvement of the detachable built-in pump of this utility model, one end face of the pump core is provided with an air inlet groove at intervals, which facilitates the air to enter the air inlet hole of the pump core. The other end face of the pump core is provided with an air outlet groove at intervals, which facilitates the air to be discharged.

[0019] The advantages of this invention are as follows: It employs an independent pump core, with both ends capable of connecting to the inlet and outlet ports. An elastic abutment assembly pre-tightens the pump core, making installation and removal convenient. When the outlet end of the pump core is aligned with the inlet and outlet ports, inflation is achieved; reversing the pump core to align the inlet end with the inlet and outlet ports enables evacuation. This invention eliminates the complex structure of changing the air passage via a knob, resulting in a simpler structure. Attached Figure Description
