[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0048] Please see Figure 1-7 A pump body structure capable of discharging residual water includes a water pump 1 and an air pump 2, wherein at least a portion of the housing of the water pump 1 is integrally connected to a portion of the housing of the air pump 2. The water outlet 102 of the water pump is connected to the air outlet 202 of the air pump through the integrally connected housing portion, forming a gas-liquid mixing output channel 3.

[0049] Water pump 1 operates by pumping liquid into the pump from the inlet 101 and out from the outlet 102 to supply water. After the water supply is completed, air pump 2 operates by pressurizing gas and pumping it out from the outlet 202. The pressurized gas flows through the gas-liquid mixing output channel 3 to the outlet 102 of the water pump to discharge the residual water at the outlet 102.

[0050] In this embodiment, the integrated design effectively reduces the need for external pipe connections, facilitating the drainage of residual water at the pump outlet. When applied to water supply equipment, this integrated pump body structure can be directly used for assembly, simplifying the assembly process.

[0051] In some embodiments, the water outlet 102 of the water pump is located at the front end of the water pump, the air outlet 202 of the air pump is located at the front end of the air pump, and at least the front end housing 4a of the water pump and the front end housing 4b of the air pump are integrally connected.

[0052] The water pump outlet 102 can be connected to the air pump outlet 202 through the front housing 4a and 4b, forming the aforementioned gas-liquid mixing output channel 3. This can be understood as the front housing having a channel connecting the water pump outlet and the air pump outlet. With this configuration, the distance between the air outlet and the water outlet can be shorter, facilitating faster output of pressurized air to the water outlet for quick drainage.

[0053] In some embodiments, the front housing 4a of the water pump has an extension 5 extending toward the front housing 4b of the air pump, and the extension 5 is integrally connected to the front housing 4b of the air pump.

[0054] like Figure 2 As shown, in some embodiments, after the front housing 4a of the water pump and the front housing 4b of the air pump are integrally connected by the extension 5, the extension allows the rear end of the water pump and the rear end of the air pump to be separated.

[0055] Specifically, the water pump motor 6 of the water pump is located at the rear end of the water pump, and the air pump motor 7 of the air pump is located at the rear end of the air pump. The extension allows the water pump motor 6 located at the rear end of the water pump and the air pump motor 7 located at the rear end of the air pump to be separated, reducing the temperature impact caused by direct heat transfer between the two motors.

[0056] The water pump motor 6 serves as a power component, which can drive the water pump assembly (not shown, located inside the water pump) to pump the liquid at the water pump inlet to the water pump outlet.

[0057] The air pump motor 7 serves as a power component, which can drive the air pumping component (not shown, located inside the air pump) to pump the air at the air inlet to the air outlet of the air pump.

[0058] In some embodiments, the axial direction of the water pump motor 6 is the same as that of the air pump motor 7, both being front-to-back oriented.

[0059] In some embodiments, the front housing of the water pump includes a water pump cover 8. The front housing of the air pump includes an air pump cover 9. The water pump cover 8 extends toward the air pump cover 9 to form the aforementioned extension 5, and the extension 5 is integrally connected to the air pump cover 9.

[0060] In some embodiments, the water pump cover 8 includes a first front cover 801 connected to the housing of the water pump and a second front cover 802 detachably connected to the first front cover. The extension 5 includes a first extension 501 located on the first front cover and a second extension 502 located on the second cover. The air pump cover 9 includes a third front cover 901 connected to the housing of the air pump and a fourth front cover 902 detachably connected to the third front cover. The third front cover 901 is integrally connected to the first extension 51, and the fourth front cover 902 is integrally connected to the second extension 501.

[0061] In some embodiments, a second front cover 802 is configured to be connected to the front side of a first front cover 801. A fourth front cover 902 is configured to be connected to the front side of a third front cover 901.

[0062] In some embodiments, the outlet of the water pump extends forward through the first front cover 801 and the second front cover 802 to form a first water outlet position 102a on the first front cover and a second water outlet position 102b on the second front cover.

[0063] The air outlet of the air pump extends forward through the third front cover 901 to form an air outlet position 202a on the third front cover. The fourth front cover 902 has a communicating air groove 202b that communicates with the air outlet position.

[0064] A first channel groove 3a is formed on the side of the first extension 501 corresponding to the second extension 502. The first channel groove 3a extends to communicate with the first water outlet position 102a and extends to communicate with the air outlet position 202a.

[0065] A second channel groove 3b is formed on the side of the second extension 502 corresponding to the first extension 501. The second channel groove 3b extends to communicate with the second water outlet 102b and extends to communicate with the communicating air groove 202b.

[0066] The first channel groove 3a and the second channel groove 3b combine to form the aforementioned gas-liquid mixing output channel 3.

[0067] In some embodiments, a sealing gasket is provided between the first front cover and the second front cover.

[0068] In some embodiments, a sealing gasket is provided between the third front cover and the fourth front cover.

[0069] In some embodiments, a sealing gasket is provided between the first extension and the second extension.

[0070] In some embodiments, the sealing gasket 10 is disposed between the first channel groove 3a and the second channel groove 3b to divide the gas-liquid mixing output channel 3 into a double-layer channel with front and rear separation, wherein the cross-sectional area of ​​each layer of the double-layer channel is correspondingly smaller.

[0071] like Figure 6 As shown, in some embodiments, in the double-layer channel, the cross-sectional area of ​​the channel corresponding to the second channel groove 3b is greater than the cross-sectional area of ​​the channel corresponding to the first channel groove 3a.

[0072] In some embodiments, the sealing gasket 10 has a first connecting hole 10a, and the first water outlet 102a is connected to the second water outlet 102b through the first connecting hole 10a.

[0073] The sealing gasket 10 has a second connecting hole 10b, and the air outlet 202a is connected to the connecting air groove 202b through the second connecting hole 10b.

[0074] In this embodiment, the sealing gasket 10 effectively prevents water from flowing back into the air pump 2, thus providing better protection for the air pump with its integrated pump body structure.

[0075] In some embodiments, the second front cover is connected to the housing having the first front cover by means of multiple bolts.

[0076] In some embodiments, a fourth front cover is attached to a housing having a third front cover by means of multiple bolts.

[0077] In this embodiment, a formula maker includes the pump body structure of any of the above embodiments.

[0078] In some embodiments, the formula maker further includes a water storage device (not shown) for supplying water to the inlet of the water pump, and a water pipe (not shown) for receiving water from the outlet of the water pump. The water pipe has a water outlet for discharging water to the outside. When the water pump operates, it pressurizes the water in the water storage device and delivers it to the water pipe, and then discharges the water to the outside through the water outlet. After the water pumping is completed, the air pump 2 operates by pressurizing gas and pumping it out from the air outlet 202 of the air pump. The pressurized gas flows through the gas-liquid mixing output channel 3 to the outlet 102 of the water pump, and finally discharges the gas through the water pipe to the water outlet, thereby discharging the residual water at the outlet 102 of the water pump and in the water pipe.

[0079] In the description of this embodiment, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.

[0080] For example, when the water pump is attached Figure 2 The front and back placement shown is adjusted to the attached Figure 1 When the pump is placed vertically as shown, the front end of the pump can be adjusted to face downwards or upwards. At this time, the front end of the pump is adjusted to what is called the upper end or the lower end of the pump, and the rear end of the pump is adjusted to what is called the lower end or the upper end of the pump.
