In order to fully understand the present invention, the following detailed description is given with reference to the accompanying drawings. The objects, features and functions of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. It is to be noted that the present invention may be practiced or applied in other embodiments and that various modifications and changes may be made in the details of the description without departing from the spirit of the invention. In addition, the drawings attached to the present invention are only for simple schematic illustration and are not drawn to actual dimensions. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the claims of the present invention. The description is as follows:

as shown in fig. 1 and 2, a gas-liquid conveying apparatus 100 according to an embodiment of the present invention includes: the pump comprises a pump body 1, a linear transmission mechanism 2, a one-way air inlet and outlet mechanism 3 and a one-way liquid inlet and outlet mechanism 4.

The pump body 1 includes a stationary housing 11, a pump member 12, the pump member 12 having a rotary shaft 121 for outputting rotary power (as indicated by an arrow in fig. 2).

The linear transmission mechanism 2 is disposed on the rotating shaft 121 and the fixed housing 11, and is used for converting the rotating motion output by the rotating shaft 121 into a linear reciprocating motion with a direction perpendicular to the rotating shaft 121. The reciprocating direction L shown in fig. 2 is a moving direction of the linear reciprocating motion.

The one-way air inlet and outlet mechanism 3 is connected to the linear transmission mechanism 2 and the fixed housing 11, and the one-way air inlet and outlet mechanism 3 sucks air from the air inlet 33 and exhausts air from the air outlet 34 in the reciprocating direction L perpendicular to the rotation axis 121 by the linear reciprocating motion of the linear transmission mechanism 2.

The one-way liquid inlet and outlet mechanism 4 is connected to the rotating shaft 121 and the fixed housing 11, and the one-way liquid inlet and outlet mechanism 4 conveys the liquid flowing in from the liquid inlet 43 to the liquid outlet 44 through the rotating motion output by the rotating shaft 121.

Through the above design, the utility model discloses a gas-liquid conveying device can only use a pump component 12, a single rotation axis 121, can reach the effect of carrying gas and liquid respectively simultaneously. Not only saves the number of components, reduces the volume of the device, makes the assembly change easy, but also can effectively reduce the cost.

Further, as shown in fig. 2, in the present embodiment, the linear transmission mechanism 2 includes an eccentric 21, a bearing 22, and a reciprocating transmission member 23 provided to the stationary housing 11. The eccentric wheel 21 is sleeved on the rotating shaft 121 at an eccentric position, and the bearing 22 is sleeved on the eccentric wheel 21, so that the eccentric wheel 21 rotates in the bearing 22. The reciprocating transmission member 23 is sleeved on the bearing 22, and the outer periphery of the reciprocating transmission member 23 is provided with an ejector 231 protruding outward toward the reciprocating transmission member 23. The reciprocating transmission member 23 causes the pushing member 231 to reciprocate in the reciprocating direction L by the rotational movement of the eccentric 21 and the rotating shaft 121, thereby reciprocally pushing the one-way air inlet/outlet mechanism 3. Thereby, the rotational motion of the rotation shaft 121 is converted into the linear reciprocating motion in the direction perpendicular to the rotation shaft 121 by the eccentric rotational motion of the eccentric wheel 21.

Further, as shown in fig. 2, in the present embodiment, the linear transmission mechanism 2 further includes a rotating shaft sealing member 24, which is sleeved on the rotating shaft 121 and located in the accommodating groove 411 of the one-way liquid inlet and outlet mechanism 4. Thereby, the rotary shaft sealing member 24 can prevent the liquid flowing through the one-way liquid inlet and outlet mechanism 4 from penetrating to the linear transmission mechanism 2 and the pump member 12 along the rotary shaft 121.

Further, as shown in fig. 2 to 3B, in the present embodiment, the one-way air inlet and outlet mechanism 3 includes a suction cup member 31 disposed on the fixed housing 11 and a thin film one-way valve member 32 disposed on the fixed housing 11. The end 311 of the suction member 31 is connected to the linear actuator 2, the suction surface 312 of the suction member 31 is connected to the film check valve member 32, and the film check valve member 32 communicates with the air inlet 33 and the air outlet 34, respectively. Thus, by the combination of the suction member 31 and the film check valve member 32 and the linear reciprocating motion converted by the linear transmission mechanism 2, the suction member 31 is repeatedly compressed and expanded, and the air flow is unidirectionally transmitted from the air inlet 33 to the air outlet 34 via the film check valve member 32, and the air with a certain pressure is output to make the finally generated foam full.

Further, as shown in fig. 2 to 3B, in the present embodiment, the film check valve member 32 includes a front half valve 321, a rear half valve 322 and an elastic film 323, the front half valve 321 is disposed in the fixed housing 11 and is communicated with the suction cup member 31, and the rear half valve 322 is communicated with the air inlet 33 and the air outlet 34, respectively. The front half valve 321 and the rear half valve 322 are clamped to form the air containing space 35, and the elastic film sheet 323 is arranged in the air containing space 35. The suction member 31 changes the flow direction of the gas in the gas containing space 35 to reciprocally vibrate the elastic film 323, and the reciprocal vibration of the elastic film 323 causes the gas flow to enter the gas containing space 35 from the gas inlet 33 and flow out from the gas outlet 34.

Further, as shown in fig. 3A and 3B, in this embodiment, the rear half valve 322 has a rear convex portion 322a communicating with the inlet port 33 and a rear concave portion 322B communicating with the outlet port 34, the front half valve 321 has a front concave portion 321a opposite to the rear convex portion 322a and a front convex portion 321B opposite to the rear concave portion 322B, and the elastic thin film sheet 323 has two elastic valve bodies 323A, 323B respectively located between the front concave portion 321a and the rear convex portion 322a and between the front convex portion 321B and the rear concave portion 321B. The front notch portion 321a and the front boss portion 321b communicate with the suction cup member 31. When the suction cup member 31 sucks air, the air smoothly enters the air containing space 35 from the air inlet 33 through the rear convex portion 322 a; the two elastic valve bodies 323a, 323b are pulled toward the suction cup member 31, wherein the elastic valve body 323b abuts against the front flange 321b, so that the front flange 321b is blocked and the air cannot be directly sucked into the rear recess 321b, and therefore the air cannot flow backward from the air outlet 34 into the air accommodating space 35. When the suction cup member 31 is compressed, the air flows from the suction cup member 31 into the air accommodating space 35, and drives the two elastic valve bodies 323a and 323b to be away from the suction cup member 31, and at this time, the elastic valve body 323a abuts against the rear convex opening 322a, so that the air flow is not discharged through the air inlet 33; while gas is discharged from the membrane check valve member 32 through the gas outlet 34 from the rear recess portion 321 b. In summary, the membrane check valve assembly achieves the effect of a gas check valve by using the design of the two elastic valve bodies 323a and 323b, the front notch 321a, the front convex 321b, the rear convex 322a and the rear concave 321 b.

Further, as shown in fig. 2, in the present embodiment, the one-way liquid inlet and outlet mechanism 4 includes a liquid inlet and outlet housing 41 and a gear train 42 disposed on the fixed housing 11. The liquid inlet/outlet housing 41 has a liquid containing space 45, and a liquid inlet 43 and a liquid outlet 44 communicating with the liquid containing space 45, the gear train 42 is provided in the liquid containing space 45, and the gear train 42 is rotated by the rotation of the rotary shaft 121 to transfer the liquid flowing from the liquid inlet 43 to the liquid outlet 44. Therefore, the unidirectional liquid inlet and outlet mechanism 4 can directly utilize the rotation power of the rotating shaft 121 to convey liquid.

Further, as shown in fig. 2, in the present embodiment, the gear set 42 includes a driving gear 421 directly driven by the rotating shaft 121 and a driven gear 422 driven by the driving gear 421. The gear set 42 further includes a gear seat 423 and a sealing ring 424, the gear seat 423 is disposed in the liquid containing space 45 to communicate with the liquid outlet 44, and the sealing ring 424 is disposed between the gear seat 423 and the liquid inlet/outlet housing 41 to seal the gear seat 423 and the liquid inlet/outlet housing 41. When the rotating shaft 121 rotates, the driving gear 421 and the driven gear 422 are driven to rotate in the gear seat 423, and a tangential direction of an engagement position of the driving gear 421 and the driven gear 422 faces the liquid outlet 44, so that when liquid enters the liquid containing space 45 from the liquid inlet 43, the liquid is continuously brought to the liquid outlet 44 by the rotation of the driving gear 421 and the driven gear 422. In addition, a one-way valve plate 441 may be disposed in the liquid outlet 44 to prevent liquid from flowing back into the liquid inlet/outlet housing 41.

Further, as shown in fig. 4, the gas-liquid conveying apparatus 100a according to the second embodiment of the present invention is substantially the same as the gas-liquid conveying apparatus 100 according to the first embodiment of fig. 2, and the difference is that the gas-liquid conveying apparatus 100a further includes a speed reducing mechanism 5, the speed reducing mechanism 5 is sleeved on the rotating shaft 121 and located between the linear transmission mechanism 2 and the one-way liquid inlet and outlet mechanism 3, and the speed reducing mechanism 5 is used for reducing the rotation speed of the gear set 42. The rotational speed of the gear set 42 is adjusted by means of the reduction mechanism 5, so that the flux of gas and liquid per unit time can also be adjusted to a desired ratio. In one example, the preferred gas-to-liquid ratio is between 1:4 and 1: 40.

Further, as shown in fig. 4, in the present embodiment, the speed reducing mechanism 5 includes a small driving wheel 51, a large driven wheel 52 and a transmission belt 53, and the small driving wheel 51 is sleeved on the rotating shaft 121 and directly driven by the rotation of the rotating shaft 121. The driving belt 53 connects the small driving pulley 51 and the large driven pulley 52 to rotate the large driven pulley 52 at a reduced speed, and the driving gear 421 of the gear train 42 rotates coaxially 54 with the large driven pulley 52. Therefore, the diameter ratio of the small driving wheel 51 to the large driven wheel 52 is adjusted, and the effect of controlling the reduction ratio of the gear set 42 is achieved.
