Description

Technical Field

[0001] The present invention relates to a gas-liquid mixing pump, and more particularly to a gas-liquid mixing pump which can be used inverted and can prevent liquid leakage. Background Art

[0002] Foam pumps have been widely used in daily life. People set a foam pump on a container. The foam pump absorbs liquid in the container by pressing and mixes it with gas to form foam.

[0003] However, such foam pumps often have the problem of leaking when inverted. Figure 7 As shown, the foam pump of the prior art uses the ball B as a one-way valve. When the foam pump is inverted, the liquid is on the top, and the ball B follows the direction of gravity G and leaves the originally tightly closed position, so that the liquid flows out from the gap between the ball B and the tube wall, thereby causing the liquid to drip from the opening until all the liquid leaks out. Summary of the invention

[0004] Therefore, in order to solve various problems of the existing foam pumps, the present invention provides a leak-proof liquid-gas-liquid mixing pump that can be used inverted.

[0005] To achieve the above-mentioned and other purposes, the present invention provides an invertible leak-proof liquid-gas-liquid mixing pump for connecting a liquid container, the invertible leak-proof liquid-gas-liquid mixing pump comprising: a lower shell, including a liquid channel portion and an outer shell portion, the outer shell portion surrounding the liquid channel portion; a pressing member, including a pressing portion, a liquid guide portion and a first spring, the pressing portion having a gas-liquid mixing channel, the liquid guide portion being unidirectionally connected toward the pressing portion, the first spring abutting between the pressing portion and the lower shell so that the liquid guide portion is movably disposed on the liquid channel portion, a liquid chamber is formed between the liquid guide portion and the liquid channel portion, the liquid container is unidirectionally connected to the liquid chamber through the liquid channel portion, and the liquid chamber is connected to the liquid chamber The liquid guide portion is unidirectionally connected, an air chamber is formed between the pressing portion, the liquid channel portion and the shell portion, the air chamber is unidirectionally connected toward the pressing portion, and the external atmosphere is unidirectionally connected toward the air chamber; and an upper shell surrounds the pressing member and connects the shell portion and the liquid container; wherein the liquid guide portion includes a cover portion, a sealing piston, a second spring and a tube body unidirectionally connected toward the pressing portion, the cover portion is connected to the bottom end of the tube body, the diameter of the cover portion is larger than the diameter of the tube body and smaller than the diameter of the liquid channel portion, the tube body is provided with at least one through hole near the cover portion, and the second spring causes the sealing piston to abut against the cover portion to seal the through hole, so that the liquid chamber is unidirectionally connected toward the tube body.

[0006] In an embodiment of the present invention, an outer peripheral edge of the cover portion protrudes toward the sealing piston, and the sealing piston abuts against the outer peripheral edge.

[0007] In an embodiment of the present invention, the sealing piston has a guiding inclined surface, and the guiding inclined surface is arranged on the inner side of the sealing piston and close to the cover portion.

[0008] In an embodiment of the present invention, the liquid guiding portion includes a push ring, which surrounds the tube body and abuts between the sealing piston and the second spring.

[0009] In an embodiment of the present invention, two one-way valves are further included, which are respectively arranged on the liquid channel portion and the pressing portion, so that the liquid container is connected to the liquid chamber in one direction through the liquid channel portion, and the liquid guide portion is connected to the pressing portion in one direction.

[0010] In an embodiment of the present invention, a one-way air intake piston is further included, and the one-way air intake piston is sleeved on the pressing portion to allow the external atmosphere to communicate with the air chamber in one direction.

[0014] Thus, the invertible leak-proof liquid-gas-liquid mixing pump of the present invention improves various shortcomings of the prior art. When the invertible leak-proof liquid-gas-liquid mixing pump of the present invention is used inverted, even if the pressing part is pressed down a certain distance, or the liquid container is slightly squeezed, the liquid will not drip out, thereby improving the stability in use. In addition, the invertible leak-proof liquid-gas-liquid mixing pump of the present invention can replace the traditional gravity-type steel ball one-way valve with the one-way valve of the butterfly valve plate, and can be used in any direction without worrying about leakage, and the one-way valve of the butterfly valve plate also reduces the load compared with the gravity-type steel ball one-way valve.

[0059] In order to fully understand the present invention, the present invention is now further described in detail through the following specific embodiments and in conjunction with the accompanying drawings. Those skilled in the art can understand the purpose, characteristics and effects of the present invention from the contents disclosed in this specification. It should be noted that the present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the inventive point of the present invention. The following implementation methods will further explain the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of the patent application of the present invention. The description is as follows:

[0060] like Figures 1 to 3 As shown, the invertible leak-proof liquid gas-liquid mixing pump 100 of the present invention is used to connect the liquid container 200 (please refer to Figure 4 ), the leak-proof liquid-gas-liquid mixing pump 100 which can be used inverted includes a lower shell 1, a pressing member 2 and an upper shell 3.

[0061] The lower housing 1 includes a liquid channel portion 11 and an outer shell portion 12. The liquid channel portion 11 is in a hollow column shape, and the outer shell portion 12 surrounds the liquid channel portion 11. The lower end of the liquid channel portion 11 can be connected to the liquid container 200 to be sucked in one direction. The liquid container 200 can contain the liquid to be sucked (such as soap liquid), and the other end of the liquid channel portion 11 is connected to the pressing member 2. The liquid channel portion 11 and the outer shell portion 12 can be placed into the liquid container 200 through the opening of the liquid container 200, so that the liquid channel portion 11 can suck the liquid in the liquid container 200.

[0062] The pressing member 2 has a pressing portion 21, a liquid guide portion 22 and a first spring 23 for the user to press. The pressing portion 21 may be connected with a pressing head 211, a sealing tube 212, a first piston member 213, a one-way air intake valve body 214, a second piston member 215 and a one-way air intake piston 216 in sequence from top to bottom. The pressing head 211 may have a gas-liquid mixing channel 211a, the sealing tube 212 is connected between the pressing head 211 and the first piston member 213 to prevent liquid leakage between the pressing head 211 and the first piston member 213, the first piston member 213 may have a mesh plug gas-liquid mixing piece 213a, the mesh plug gas-liquid mixing piece 213a is a porous mesh member, and the gas-liquid mixture may be in a foam shape after passing through the mesh plug gas-liquid mixing piece 213a, the one-way air intake valve body 214 is connected between the first piston member 213 and the second piston member 215 to temporarily seal the gas of the second piston member 215. The one-way air intake valve body 214 may have a check membrane to prevent liquid from flowing into the air chamber GS and causing uneven foam. The top of the second piston component 215 may have a gas-liquid mixing tube 215c, and the gas-liquid mixing tube 215c may have a gas-liquid mixing chamber GLS. The mesh plug gas-liquid mixing piece 213a is connected to the top of the gas-liquid mixing chamber GLS. The bottom of the second piston component 215 may have an internal connecting pipe 215b. The one-way air intake piston 216 is sleeved on the outside of the second piston component 215, and the outer edge of the one-way air intake piston 216 is temporarily arranged on the inner wall surface of the outer shell part 12 of the lower shell 1. The liquid guide portion 22 is connected to the inner connecting tube 215b of the second piston member 215 of the pressing portion 21 and the liquid channel portion 11 of the lower shell 1, and the liquid guide portion 22 is unidirectionally connected to the gas-liquid mixing tube 215c of the second piston member 215 of the pressing portion 21. The liquid in the liquid container 200 is mixed with air after passing through the liquid channel portion 11 and the liquid guide portion 22, and then enters the pressing portion 21 and flows out in the form of foam. One end of the first spring 23 abuts the bottom of the second piston member 215, and the other end of the first spring 23 abuts the bottom of the outer shell portion 12. The first spring 23 allows the liquid guide portion 22 to be movably arranged on the liquid channel portion 11. A liquid chamber LS is formed between the liquid guide portion 22 and the liquid channel portion 11, the liquid container 200 is in one-way communication with the liquid chamber LS through the liquid channel portion 11, the liquid chamber LS is in one-way communication with the liquid guide portion 22, an air chamber GS is formed between the pressing portion 21, the liquid channel portion 11 and the outer shell portion 12, the air chamber GS is in one-way communication with the pressing portion 21 through the one-way air intake valve body 214, and the external atmosphere is in one-way communication with the air chamber GS through the one-way air intake piston 216. When the pressing portion 21 is subjected to an external force and moves downward in the figure, the pressing portion 21 will drive the liquid guide portion 22 to move downward, and the first spring 23 will be compressed to accumulate elastic potential energy; when the external force on the pressing portion 21 is removed, the first spring 23 releases the elastic potential energy to push the liquid guide portion 22 and the pressing portion 21 to return to their original positions.

[0063] The upper shell 3 surrounds the pressing head 211 of the pressing portion 21, and there is a gap between the upper shell 3 and the pressing head 211. The upper shell 3 can be screwed to the opening of the liquid container 200. The outer shell 12 of the lower shell 1 is connected to the upper shell 3, and the outer abutment flange 213b of the first piston member 213 can be temporarily placed against the inner abutment flange 31 in the upper shell 3. The one-way air intake valve body 214, the second piston member 215, the one-way air intake piston 216 and the outer shell 12 can be sandwiched to form an air chamber GS, and the air chamber GS can provide gas (such as air) for mixing into foam.

[0064] like Figure 1 and Figure 3 As shown, the liquid guide portion 22 includes a cover portion 222, a sealing piston 223, a second spring 224, and a tube body 221 that is unidirectionally connected to the second piston member 215 of the pressing portion 21. The tube body 221 is a hollow tube column, at least a portion of which is disposed in the liquid channel portion 11. The cover portion 222 is connected to the bottom end of the tube body 221 and is located in the liquid channel portion 11. The bottom end of the tube body 221 is sealed by the cover portion 222 and is not directly connected to the liquid channel portion 11. A liquid chamber LS is formed between the cover portion 222 and the liquid channel portion 11. The diameter of the cover portion 222 is larger than the diameter of the tube body 221 but smaller than the diameter of the liquid channel portion 11, so there is a gap between the cover portion 222 and the liquid channel portion 11. The sealing piston 223 is sleeved on the tube body 221 to seal the gap. The tube body 221 is provided with at least one through hole 221a at the bottom end near the cover 222. One end of the second spring 224 abuts against the inner connecting tube 215b of the second piston member 215. The other end of the second spring 224 abuts against the sealing piston 223. The second spring 224 makes the sealing piston 223 abut against the cover 222 and the outer side of the tube body 221 to seal the through hole 221a, so that the liquid chamber LS is unidirectionally connected to the tube body 221. In other words, under normal conditions, the sealing piston 223 makes the tube body 221 not connected to the liquid channel portion 11.

[0065] Please refer to Figure 3 and Figure 4 , in order to avoid component symbols interfering with the display of streamlines, Figure 4 No component symbol is displayed. Figure 4 The component symbols can be found in Figure 3 Component symbol. Figure 3 and Figure 4As shown, when the pressing head 211 of the pressing part 21 is subjected to external force to drive the liquid guide part 22 to move downward and compress the first spring 23 to accumulate elastic potential energy, the volume of the liquid chamber LS (below the cover 222 in the figure) storing liquid in the liquid channel part 11 becomes smaller, and the one-way valve 5 in the liquid channel part 11 is closed, so the liquid pressure rises. The liquid with high pressure pushes the sealing piston 223 upward from the gap between the cover 222 and the liquid channel part 11. Once the liquid pressure overcomes the pressure applied to the sealing piston 223 by the second spring 224, the sealing piston 223 is lifted upward by the liquid, exposing the originally sealed through hole 221a, and then the liquid can enter the tube body 221 from the through hole 221a, and then enter the gas-liquid mixing chamber GLS in the gas-liquid mixing tube 215c of the second piston member 215 through the one-way valve 5 of the second piston member 215. After the liquid flows into the through hole 221a, the liquid pressure will gradually decrease until it cannot overcome the pressure applied by the second spring 224, and the sealing piston 223 will seal the through hole 221a again, blocking the connection between the tube body 221 and the liquid channel portion 11. In addition, when the pressing head 211 of the pressing portion 21 is pressed by an external force, the volume of the air chamber GS will also decrease and the air pressure will increase, and at the same time, the outer abutting flange 213b of the first piston member 213 will move away from the inner abutting flange 31 of the upper shell 3 to form a gap. Since the one-way air intake piston 216 does not allow the gas in the air chamber GS to reversely enter the external atmosphere, the gas in the air chamber GS can only enter the gas-liquid mixing chamber GLS in the gas-liquid mixing tube 215c of the second piston component 215 through the gas channel 215a of the second piston component 215, the one-way air intake valve body 214 and the gap between the gas-liquid mixing tube 215c of the second piston component 215 and the first piston component 213 to mix with the liquid, and then form foam through the mesh plug gas-liquid mixing piece 213a of the first piston component 213, and then the foam is discharged by the pressing head 211.

[0066] Please refer to Figure 3 and Figure 5 , in order to avoid component symbols interfering with the display of streamlines, Figure 5 No component symbol is displayed. Figure 5 The component symbols can be found in Figure 3 Component symbol. Figure 3 and Figure 5As shown, when the external force is removed, the pressing part 21 gradually returns to its original position through the elastic potential energy released by the first spring 23. At this time, the volume of the air chamber GS increases. However, the gas originally stored has been discharged, so the air pressure of the air chamber GS is lower than the air pressure of the external atmosphere. Therefore, the external atmosphere will squeeze the one-way air intake piston 216 through the gap between the pressing head 211 and the upper shell 3, the gap between the outer abutting flange 213b and the inner abutting flange 31, the gap between the outer abutting flange 213b and the outer shell 12, and the gap between the second piston member 215 and the outer shell 12, so that the air chamber GS is connected with the external atmosphere, and the external atmosphere can flow into the air chamber GS to replenish the gas. When the pressing part 21 returns to the position where the outer abutting flange 213b of the first piston member 213 is against the inner abutting flange 31 of the upper shell 3, the external atmosphere stops flowing into the air chamber GS. In addition, when the external force is removed, the liquid guide portion 22 gradually returns to its original position due to the elastic potential energy released by the first spring 23. At this time, the volume of the liquid chamber LS increases. However, the originally stored liquid has been discharged, so the pressure of the liquid chamber LS is lower than the pressure of the external atmosphere. Therefore, the external atmosphere will push the liquid in the liquid container 200 into the liquid chamber LS in the liquid channel portion 11 through the one-way valve 5 of the liquid channel portion 11 to replenish the liquid. When the liquid guide portion 22 returns to the position where the outer abutting flange 213b of the first piston member 213 is against the inner abutting flange 31 of the upper shell 3, the liquid stops flowing into the liquid chamber LS.

[0067] like Figure 6 As shown, when the inverted leak-proof gas-liquid mixing pump 100 of the present invention is inverted, the second spring 224 can make the cover 222 still close to the sealing piston 223, and the sealing piston 223 still close to the tube body 221 to seal the through hole 221a, and gravity will not affect the normal blocking of the liquid chamber LS of the tube body 221 and the liquid channel part 11. Even if the pressing head 211 of the pressing part 21 is slightly pressed, as long as the liquid pressure cannot overcome the pressure applied by the second spring 224 to the sealing piston 223, the tube body 221 and the liquid chamber LS of the liquid channel part 11 remain disconnected. Therefore, the present invention can make the gas-liquid mixing pump inverted without leaking. In addition, the structure of the inverted leak-proof gas-liquid mixing pump 100 of the present invention adopts double external springs, and the soap liquid will not contact the spring, which can prevent the soap liquid from contaminating and corroding the spring and causing the spring to fail.

[0068] In this embodiment, if Figure 1 and Figure 3 As shown, the outer peripheral edge 222a of the cover 222 protrudes toward the sealing piston 223, and the sealing piston 223 abuts against the outer peripheral edge 222a instead of the entire cover 222. By reducing the contact area between the sealing piston 223 and the cover 222, the second spring 224 can obtain a larger pressure with a relatively small force.

[0069] In this embodiment, if Figure 1 and Figure 3 As shown, the sealing piston 223 has a guiding slope 223a, which is disposed on the inner side of the bottom of the sealing piston 223 and close to the cover 222. The guiding slope 223a allows the sealing piston 223 to be slightly lifted upward so that the liquid can flow into the through hole 221a along the guiding slope 223a without the need for the entire sealing piston 223 to be away from the through hole 221a.

[0070] Furthermore, if Figure 1 and Figure 3 As shown, the liquid guide part 22 of the invertible leak-proof liquid-gas-liquid mixing pump 100 of the present invention further includes a top ring 225, which is disposed around the tube body 221 and abuts between the sealing piston 223 and the second spring 224. The second spring 224 can abut against the sealing piston 223 through the top ring 225 to increase the area of ​​the second spring 224 abutting against the sealing piston 223.

[0071] Furthermore, if Figure 1 and Figure 3 As shown, the inverted leak-proof liquid gas-liquid mixing pump 100 of the present invention further includes two one-way valves 5, which are respectively arranged in the liquid channel portion 11 and the gas-liquid mixing tube 215c of the second piston member 215 of the pressing portion 21. The one-way valve 5 is used to limit the liquid to flow in only one direction, and has an effect regardless of whether it is upright or inverted. In this embodiment, the one-way valve 5 can be a butterfly valve disc, replacing a glass ball or a steel ball valve, so it can be used inverted. When pressed, liquid flows into the gas-liquid mixing chamber GLS instantly, which causes the butterfly valve disc made of plastic sheet to bend slightly, so that the liquid flows in from the side of the butterfly valve disc. When the pressure disappears, the deformation of the butterfly valve disc bends back to the original position and blocks the liquid again, so it is suitable for inverted use. In addition, when the pressure disappears, liquid flows into the liquid chamber LS instantly, which causes the butterfly valve disc made of plastic sheet to bend slightly, so that the liquid flows in from the side of the butterfly valve disc. When pressed, the deformation of the butterfly valve disc bends back to the original position and blocks the liquid again, so it is suitable for inverted use. The one-way valve 5 has the advantages of being light and easy to assemble, but the present invention is not limited thereto, and the one-way valve 5 can be replaced by other types of one-way valve mechanisms.

[0072] like Figure 1 and Figure 3 As shown, in this embodiment, the one-way air inlet piston 216 of the pressing part 21 of the inverted leak-proof liquid-gas-liquid mixing pump 100 of the present invention can be a soft piston made of wear-resistant soft rubber. The soft piston can ensure better sealing, less friction on the inner wall, and less pull-back force required by the pump, thereby extending the service life of the pump.

[0073] The present invention has been disclosed in the above with embodiments, but it should be understood by those skilled in the art that the embodiments are only used to describe the present invention and should not be interpreted as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the embodiments should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be based on the scope defined by the claims.
