Description

Technical Field

[0001] The embodiments of this utility model relate to a pumping device, and more particularly to a medium mixing component, a gas-liquid mixing assembly, a pumping device, and a hand sanitizer. Background Technology

[0002] Liquid pumps, as a type of drive mechanism that can draw in and pump out liquid and / or gaseous media, are generally used in different pump bodies, such as diaphragm pumps, and are commonly used in various equipment, such as hand sanitizer dispensers, kitchen cleaner dispensers, and other liquid dispensing devices.

[0003] Furthermore, some liquid dispensing devices currently mix two different media during pumping. For example, hand sanitizer dispensers typically incorporate a large amount of gas before dispensing to produce abundant foam. To achieve this gas-liquid mixing, the pumping device usually includes a mixing component. However, this mixing component not only needs to collect both the gaseous and liquid media but also needs to perform the mixing process, resulting in a highly complex structure. This overly complex structure not only affects the driving force of the pumping device when dispensing the media but also hinders the miniaturization of the pumping device. Utility Model Content

[0004] The purpose of some embodiments of this utility model is to design a medium mixing component, a gas-liquid mixing assembly, a pumping device, and a handwashing machine. It can not only achieve the mixing of multiple media, but also has a simple structure, which is conducive to the miniaturization of the pumping device, thereby laying the foundation for greatly reducing the volume of liquid dispensing equipment such as handwashing machines and detergent dispensers.

[0005] To achieve the above objectives, some embodiments of the present invention provide a medium mixing component, the medium mixing component comprising:

[0006] Base plate; the base plate is provided with at least two medium inlet holes and at least two medium outlet holes;

[0007] At least two cavities are provided on the base plate and are respectively used to receive gas or liquid media; wherein, the medium received by at least one of the cavities is different from the medium received by the other cavities, and each of the cavities is respectively used to deliver gas or liquid media to the media pumping mechanism through at least one media discharge hole;

[0008] A mixing chamber, disposed on the base plate, is used to receive gaseous and / or liquid media pumped out from the media pumping mechanism through each of the media inlet holes, and to mix the received gaseous and / or liquid media.

[0009] In addition, some embodiments of the utility model also provide a gas-liquid mixing assembly, including:

[0010] The media mixing component as described above;

[0011] A gas-liquid inlet component seals each of the mold cavities and the mixing cavity, and is disposed opposite to the base plate of the medium mixing component; wherein, the gas-liquid inlet component is provided with a liquid inlet pipe for supplying liquid medium to at least one of the mold cavities and an air inlet pipe for supplying gas medium to at least another mold cavity.

[0012] In addition, some embodiments of the utility model also provide a pumping device, including:

[0013] The gas-liquid mixing assembly as described above;

[0014] A media pumping mechanism is located on the side of the base plate opposite to the media mixing component;

[0015] When the medium pumping mechanism is driven, it is used to draw gas medium through at least one of the cavities, and to draw liquid medium through at least another cavity. It is also used to pump the drawn gas medium and liquid medium to the mixing cavity, so that the gas medium and liquid medium are mixed in the mixing cavity.

[0016] In addition, some embodiments of the utility model also provide a hand sanitizer, including: the pumping device as described above.

The mixing chamber receives gaseous and / or liquid media pumped out from the media pumping mechanism through media inlet holes on the base plate and can mix the received gaseous and / or liquid media. Therefore, it is evident that this media mixing component not only achieves mixing of multiple gaseous and / or liquid media through multiple cavities and mixing chambers, but also has a simple structure, facilitating the miniaturization of pumping devices and laying the foundation for significantly reducing the volume of liquid dispensing equipment such as hand sanitizer dispensers and detergent dispensers.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0025] Example 1

[0026] The first embodiment of this utility model relates to a medium mixing component, such as... Figure 1 and Figure 3 As shown, the medium mixing component 1 includes: a base plate 11, at least two cavities 1211 and a mixing cavity 122. The base plate 11 is provided with at least two medium inlet holes 111 and at least two medium outlet holes 112.

[0027] In addition, such as Figure 1 and Figure 4 As shown, each cavity 1211 and the mixing cavity 122 are disposed on the base plate 11. Each cavity 1211 is used to receive gaseous or liquid media, and the medium received by at least one cavity 1211 is different from the medium received by the other cavities 1211. At the same time, each cavity 1211 is also used to deliver gaseous or liquid media to the media pumping mechanism 2 through at least one media discharge hole 112.

[0028] Finally, as Figure 1 and Figure 4 As shown, the mixing chamber 122 is used to receive gaseous and / or liquid media pumped out from the media pumping mechanism 2 through the media inlet holes 111, and the mixing chamber 122 is also used to mix the received gaseous and / or liquid media.

[0029] It is evident from the above that, since the base plate 11 of the media mixing component 1 is provided with at least two cavities 1211 and a mixing cavity 122, each cavity 1211 can be used to receive gaseous or liquid media, and the media received by at least one cavity 1211 is different from the media received by the other cavities 1211. Simultaneously, each cavity 1211 can also deliver gaseous or liquid media to the media pumping mechanism 2 through at least one media discharge hole 112 on the base plate 11. The mixing cavity 122 can receive gaseous and / or liquid media pumped out from the media pumping mechanism 2 through media inlet holes 111 on the base plate 11, and can mix the received gaseous and / or liquid media. Therefore, it is clear that the media mixing component of the above embodiment can not only achieve the mixing of multiple gaseous and / or liquid media by means of multiple cavities 1211 and mixing cavity 122, but also has a simple structure, which is conducive to the miniaturization of the pumping device, thus laying the foundation for greatly reducing the volume of liquid dispensing equipment such as hand sanitizer dispensers and detergent dispensers.

[0030] Specifically, in some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the media mixing component 1 includes an outer wall 14, an inner wall 15, and at least one spacer 16. The outer wall 14 surrounds the base plate 11, forming an accommodating space 12 on the base plate 11. The inner wall 15 is disposed on the base plate 11 and opposite to the outer wall 14. The inner wall 15 also forms a media storage area 121 on the base plate 11, and a mixing cavity 122 is formed between the inner wall 15 and the outer wall 14. Furthermore, as... Figure 1 As shown, each partition 16 is disposed on the base plate 11, and each partition 16 is located within the media storage area 121, and is used to jointly divide the media storage area 121 into at least two cavities 1211.

[0031] Furthermore, it is worth noting that, in order to allow the mixing chamber 122 to receive gaseous and / or liquid media pumped from the media pumping mechanism 2 through each media inlet port 111, and simultaneously to allow each cavity 1211 to supply gaseous or liquid media to the media pumping mechanism 2 through at least one media outlet port 112, in some other embodiments, such as Figure 1 and Figure 4 As shown, the orthographic projection of the mixing chamber 122 on the base plate 11 should cover the outlet side of each medium inlet hole 111, so that the mixing chamber 122 can be connected to each medium inlet hole 111 respectively. The orthographic projection of each cavity 1211 on the base plate 11 should cover the inlet side of at least one medium outlet hole 112 respectively, so that each cavity 1211 can be connected to at least one medium outlet hole 112 respectively. This allows the mixing chamber 122 and each cavity 1211 to be independent of each other, avoiding liquid cross-contamination.

[0032] Additionally, as a preferred embodiment, in some embodiments, such as Figure 1 and Figure 4 As shown, the number of medium inlet holes 111 and medium outlet holes 112 are the same, and each medium inlet hole 111 and each medium outlet hole 112 are arranged alternately on the base plate 11 around a preset axis. That is, the number of medium inlet holes 111 and medium outlet holes 112 on the medium mixer 1 is the same, so that the medium mixer 1 can pump out various gas and / or liquid media into the mixing chamber 122 of the medium mixer 1 under the driving action of the medium pumping mechanism 2, thereby achieving uniform mixing of various media.

[0033] Furthermore, since the mixing chamber 122 is disposed between the outer wall 14 and the inner wall 15, in order to allow each medium inlet hole 111 to be alternately arranged with each medium outlet hole 112 around a preset axis direction, in some embodiments, such as Figure 1 and Figure 4 As shown, the inner wall 15 is partially concave in a direction away from the outer wall 14 around a preset axis, so that the mixing chamber 122 can have multiple concave regions 123 protruding towards the medium storage area 121. Furthermore, the number of concave regions 123 is the same as the number of medium inlet holes 111, and they correspond uniquely. Simultaneously, the orthographic projection of each concave region 123 onto the base plate 11 covers the outlet side of the uniquely corresponding medium inlet hole 111, so that each medium inlet hole 111 can be alternately arranged with each medium outlet hole 112 around the preset axis. For example, in some embodiments, such as... Figure 1 and Figure 4 As shown, there are four medium inlet holes 111 and four medium outlet holes 112, with the inlet side of each medium outlet hole 112 falling within each cavity 1211, and the outlet side of each medium inlet hole 111 falling within the mixing cavity 122. Corresponding to each medium inlet hole 111, as shown... Figure 1 and Figure 4 As shown, the inner wall 15 is partially concave inward toward the direction away from the outer wall 14 around the preset axis, so that the mixing chamber 122 can have four concave areas 123 protruding toward the medium storage area 121, and each concave area 123 can surround around the preset axis, thereby ensuring that each medium inlet hole 111 and each medium outlet hole 112 can be alternately arranged around the preset axis, so that each medium inlet hole 111 can complete the absorption of various gas and / or liquid media through each cavity 1211 under the driving action of the medium pumping mechanism 2, and each medium outlet hole 112 can also pump the absorbed various gas and / or liquid media into the mixing chamber 122 of the medium mixer 1 under the driving action of the medium pumping mechanism 2, so that the mixing chamber 122 can realize the mixing of various gas and / or liquid media.

[0034] Furthermore, as a preferred embodiment, in some embodiments, such as Figure 1 and Figure 4 As shown, each concave area 123 can be equidistantly arranged around a preset axis, so that the medium storage area 121 enclosed by the inner wall 15 can be approximately "cross-shaped" in structure. This allows the medium inlet holes 111 and the medium outlet holes 112 to be alternately arranged around the preset axis on the bottom plate 11, and the medium inlet holes 111 and the medium outlet holes 112 can also be equidistantly arranged around the preset axis on the bottom plate 11. This ensures the pressure balance of the medium mixing component 1 when it draws in and pumps out various gaseous and / or liquid media.

[0035] Furthermore, it is not difficult to see from the above that, due to the approximately "cross-shaped" structural design of the media storage area 121, in some embodiments, the media mixing component 1 of this embodiment can be applied to a hand sanitizer dispenser. The media sprayed from the hand sanitizer dispenser generally contains abundant foam, meaning that liquid and gaseous media need to be mixed within the hand sanitizer dispenser to achieve foaming. Therefore, in some embodiments, such as... Figure 1 As shown, two partitions 16 can be provided, and the two partitions 16 can be arranged opposite to each other, thereby dividing the medium storage area 121 into three cavities 1211. One cavity 1211 can be used as a gas cavity, and the other two cavities 1211 can be used as liquid cavities. At the same time, the gas cavity is located between the two liquid cavities, separating the two liquid cavities. Corresponding to the two liquid cavities and one gas cavity, two medium discharge holes 112 can be used as liquid discharge holes, and the other two medium discharge holes 112 can be used as vent holes. The inlet side of the two vent holes falls in the gas cavity and is arranged opposite to each other along the length of the gas cavity. The inlet side of the two liquid discharge holes falls in the two liquid cavities respectively. That is, in this embodiment, the number of liquid discharge holes and vent holes is the same. Therefore, when the gas medium and liquid medium enter the mixing cavity 122 through the medium inlet holes 111, the gas medium and liquid medium can be mixed in a 1:1 ratio, thus laying the foundation for the foaming requirements after gas-liquid mixing.

[0036] Furthermore, it should be noted that the above-mentioned gas medium and liquid medium are only described using a 1:1 mixing ratio as an example. In actual applications, the gas medium and liquid medium can be mixed in other ratios according to actual usage requirements. Therefore, in some embodiments, at least one medium discharge hole 112 can be used as a liquid discharge hole, and at least another medium discharge hole 112 can be used as an exhaust hole. In this embodiment, the mixing ratio of gas medium and liquid medium is not specifically limited.

[0037] Example 2

[0038] Embodiment 2 of this utility model relates to a gas-liquid mixing component, such as... Figure 2 and Figure 3As shown, the gas-liquid mixing assembly includes: a media mixing component 1 and a gas-liquid inlet component 3 as described in Embodiment 1.

[0039] Among them, such as Figure 2 and Figure 3 As shown, the gas-liquid inlet 3 is used to seal each cavity 1211 and mixing cavity 122, and is arranged opposite to the base plate 11 of the medium mixing component 1. Secondly, combined with... Figure 4 As shown, the gas-liquid inlet 3 is provided with a liquid inlet pipe 31 for conveying liquid medium to at least one cavity 1211 and an air inlet pipe 32 for conveying gas medium to at least another cavity 1211.

[0040] As can be seen from the above, since the gas-liquid inlet 3 can seal each cavity 1211 and mixing cavity 122 of the medium mixing component 1, and the gas-liquid inlet 3 is also provided with a liquid inlet pipe 31 and an air inlet pipe 32, and the liquid inlet pipe 31 can supply liquid medium to at least one cavity 1211, while the air inlet pipe 32 can supply gas to at least another cavity 1211, the gas-liquid mixing component can achieve mixing of gas medium and liquid medium, laying the foundation for the foaming requirements after gas-liquid mixing.

[0041] Specifically, in some embodiments, such as Figure 3 As shown, the gas-liquid inlet component 3 includes a cover plate 33 and a side plate 34. The cover plate 33 is used to close each cavity 1211 and the mixing cavity 122, and the cover plate 33 is positioned opposite to the base plate 11. The cover plate 33 is also detachably connected to the side of the outer wall 14 away from the base plate 11; for example, the cover plate 33 and the outer wall 14 can be connected by snap-fit ​​or screw locking. Secondly, as... Figure 3 As shown, the side plate 34 is arranged circumferentially around the cover plate 33, and the side plate 34 forms an air intake area 35 on the cover plate 33. Additionally, as... Figure 2 and Figure 3 As shown, both the liquid inlet pipe 31 and the air inlet pipe 32 are mounted on the cover plate 33. The air inlet pipe 32 is also connected to the air inlet area 35, while the liquid inlet pipe 31 is used to connect to an external liquid storage container (not shown in the figure). This allows the air inlet pipe 32 and the liquid inlet pipe 31 to be independent of each other and to deliver gaseous and liquid media to different cavities 1211 respectively.

[0042] Furthermore, in order for the intake pipe 32 to deliver a gaseous medium to at least one of the cavities 1211, such as Figure 2 and Figure 3 As shown, the intake pipe 32 can be installed inside the cover plate 33, and combined with... Figure 4As shown, the air inlet pipe 32 has at least one air outlet, and each air outlet can be connected to at least one cavity 1211, thereby enabling the air inlet pipe 32 to deliver a gaseous medium to at least one cavity 1211. Similarly, in order for the liquid inlet pipe 31 to deliver a liquid medium to at least another cavity 1211, such as... Figure 4 As shown, the liquid inlet pipe 31 includes: an external pipe 311 protruding from the side of the cover plate 33 away from the bottom plate 11, and an internal passage 312 disposed in the cover plate 33. The external pipe 311 is used to connect to an external liquid storage container, and the internal passage 312 has at least one liquid outlet end, and each liquid outlet end can be connected to at least one other cavity 1211, so that the liquid inlet pipe 31 can deliver liquid medium to at least one cavity 1211.

[0043] Example 3

[0044] Embodiment 3 of this utility model relates to a pumping device, such as... Figure 1 As shown, the pumping device includes: a gas-liquid mixing assembly as described in Embodiment 2, and a medium pumping mechanism 2. Wherein, combined with... Figure 2 and Figure 3 As shown, the medium pumping mechanism 2 is located on the side of the base plate 11 away from the medium mixing component 1.

[0045] Therefore, when the medium pumping mechanism 2 is driven, the medium pumping mechanism 2 is used to draw gas medium through at least one cavity 1211. At the same time, the medium pumping mechanism 2 is also used to draw liquid medium through at least another cavity. Finally, the medium pumping mechanism 2 is also used to pump the drawn gas medium and liquid medium to the mixing cavity 122, so that the gas medium and liquid medium are mixed in the mixing cavity 122.

[0046] As can be seen from the above, since the pumping device includes a gas-liquid mixing component and a medium pumping mechanism 2, and the medium pumping mechanism 2 is located on the side of the base plate 11 away from the medium mixing component 1, when the medium pumping mechanism 2 is driven, the gas-liquid mixing component can absorb gas and liquid media, and at the same time, it can pump the absorbed gas and liquid media into the mixing chamber 122 of the medium mixing component 1, thereby realizing the mixing of gas and liquid media.

[0047] Furthermore, in order to enable the gas-liquid mixing assembly to mix gaseous and liquid media under the drive of the media pumping mechanism 2, in some embodiments, such as Figure 3 and Figure 5As shown, the media pumping mechanism 2 includes a cavity 21, an impeller 22, and a drive module 25. The cavity 21 is located on the side of the base plate 11 opposite to the gas-liquid inlet 3 and is enclosed by the base plate 11. This cavity 21 is used to transport gaseous and liquid media. The impeller 22 is rotatably disposed within the cavity 21 and can divide the cavity 21 into at least four chambers 211. Each chamber 211 is used to deform the impeller 22 during rotation, causing at least two chambers 211 to generate negative pressure. These negative pressures allow the impeller to draw in gaseous and liquid media through corresponding media discharge holes 112, while simultaneously generating positive pressure in at least two other chambers 211. The drawn-in gaseous and liquid media can then be pumped out through corresponding media inlet holes 111 into the mixing chamber 122 of the media mixing component 1. Finally, as... Figure 3 As shown, the drive module 25 is also connected to the impeller 22, and the drive module 25 is used to drive the impeller 22 to rotate within the cavity 21.

[0048] It is easy to see that since the media pumping mechanism 2 includes a cavity 21 and an impeller 22 rotatably disposed in the cavity 21, gas and liquid media can be transported through the cavity 21. The impeller 22 can divide the cavity 21 into at least four chambers 211. Furthermore, the rotation of the impeller 22 in the cavity 21 can cause deformation of each chamber 211. At this time, at least two chambers 211 can generate negative pressure and be used to draw in gas and liquid media respectively. At the same time, at least two other chambers 211 can generate positive pressure and be used to pump the drawn gas and liquid media into the mixing chamber 122 respectively. Thus, the media pumping mechanism 2 can not only draw in and pump out gas and liquid media by means of the deformation of each chamber 211, but also greatly simplify the structure of the media pumping mechanism 2 since the drawing in and pumping out of gas and liquid media are completed in each chamber 211 of the cavity 21. This lays the foundation for reducing the size of the hand sanitizer and is conducive to the miniaturization of the hand sanitizer.

[0049] Specifically, in some embodiments, such as Figure 3 As shown, the medium pumping mechanism 2 further includes: a housing 23 and a partition 24. The housing 23 includes: a sidewall 231 circumferentially surrounding the base plate 11, and the sidewall 231 forms a cavity 21 on the base plate 11. Meanwhile, as shown... Figure 1As shown, the partition 24 is detachably disposed on the side of the sidewall 231 away from the bottom plate 11. For example, the partition 24 can be connected to the sidewall 231 away from the bottom plate 11 using bolts or other locking devices. The partition 24 can be used to seal the cavity 21, so that each impeller 22 can be completely housed in the cavity 21. At the same time, the side of the partition 24 away from the bottom plate 11 can also be used to fix the drive module 25, so that the drive module 25 can drive the impeller 22. Therefore, when the impeller 22 rotates, as shown in Figure 4, at least two of the chambers 211 can generate negative pressure, and the gas medium and liquid medium in the corresponding cavity 1211 can be drawn in through the medium discharge holes 112 communicating with each chamber 211 respectively. At the same time, positive pressure is generated in at least two other chambers 211, and the gaseous and liquid media that have been absorbed are pumped out into the mixing chamber 122 of the media mixing member 1 through the medium inlet holes 111 connected to each chamber 211, thereby realizing the mixing of gaseous and liquid media.

[0050] Furthermore, in order for the impeller 22 to divide the cavity 21 into multiple chambers 211, in some embodiments, such as Figure 5 and Figure 6 As shown, the impeller 22 includes an impeller body 221 and at least one blade 222. The impeller body 221 is rotatably disposed within the cavity 21, and the impeller body 221 has a connecting hole 223 along a predetermined axis. This connecting hole 223 is used to connect with the main shaft 251 of the drive module 25. For example, a portion of the wall of the connecting hole 223 protrudes to form at least one keyway (not shown in the figure), allowing the main shaft 251 and the connecting hole 223 to be positioned by a key. That is, the main shaft 251 is provided with at least one key that can be inserted into the keyway around its circumference. The cooperation between the key and the keyway allows the main shaft 251 and the impeller 22 to be circumferentially fixed. Meanwhile, as... Figure 5 and Figure 6 As shown, the impeller body 221 includes: an inner surface 2211 forming a connecting hole 223 around a predetermined axis, and an outer surface 2212 opposite to the inner surface 2211, wherein, as Figure 3 , Figure 5 and Figure 6As shown, each blade 222 is connected to the outer surface 2212 of the impeller body 221, and each blade 222 also elastically abuts against the side wall 231 of the housing 23, so that a chamber 211 can be formed between each pair of adjacent blades 222. Therefore, when the impeller body 221 rotates, the elastic abutment between each blade 222 and the side wall 231 of the housing 23 causes the volume of each chamber 211 to continuously change. Each chamber 211 generates negative pressure when its volume increases, which can draw in gas or liquid media. At the same time, each chamber 211 generates positive pressure when its volume decreases, which can pump the drawn gas or liquid media into the mixing chamber 122 of the media mixing member 1. Furthermore, it is worth noting that in some embodiments, the volume change states of each pair of adjacent chambers 211 are opposite, that is, when the volume of one chamber 211 continuously increases, the volume of the adjacent chamber 211 continuously decreases.

[0051] For example, in some embodiments, the volume of each chamber 211 can periodically change between large and small volumes as the impeller 22 rotates. That is, when the volume of one of the chambers 211 continuously increases and generates negative pressure as the impeller 22 rotates, the chamber 211 can absorb liquid or gas medium through the medium discharge hole 112 currently connected to it on the bottom plate 11. As the impeller 22 continues to rotate, the volume of the chamber 211 will continuously decrease and generate positive pressure. At this time, the chamber 211 can pump the absorbed liquid or gas medium into the mixing chamber 122 of the medium mixing component 1 through the medium inlet hole 111 connected to it on the bottom plate 11.

[0052] It is worth mentioning that, in order to enable the impeller 22 to deform through the elastic contact between each blade 222 and the side wall 231 of the housing 23, so that each chamber 211 can periodically change between large and small volumes, in some embodiments, such as Figure 5 and Figure 6 As shown, each blade 222 can be a flexible blade, and each blade 222 can undergo bending deformation when the impeller body 221 rotates, causing the volume of each chamber 211 to continuously change. Specifically, in some embodiments, such as Figure 5 and Figure 6 As shown, the total length of each blade 222 is greater than the maximum distance from the outer surface 2212 of the impeller body 221 to the inner surface 2311 of the sidewall 231. This ensures that no matter how the impeller 22 rotates, each blade 222 can abut against the inner surface 2311 of the sidewall 231, thus ensuring that the blade 222 can always undergo bending deformation. And corresponding to each blade 222 of the impeller 22, as... Figure 5 and Figure 6As shown, the inner surface 2311 of the sidewall 231 is an irregular structure with multiple arc surfaces. When the impeller 22 rotates, the bending radius of each blade 222 can be continuously changed by the contact between the inner surface 2311 of the sidewall 231 and each blade 222, so that each chamber 211 can achieve periodic changes between large and small volumes.

[0053] Furthermore, it is worth noting that when the impeller 22 rotates, in order to allow the inner surface 2311 of the sidewall 231 to continuously change the volume of each chamber 211 in accordance with the blades 222, in some embodiments, such as Figure 5 and Figure 6 As shown, the inner surface 2311 of the sidewall 231 includes at least one first arc surface 23111 and at least one second arc surface 23112. Each first arc surface 23111, in its rotational direction around the impeller 22, includes a first head side 231111 and a first tail side 231112 away from the first head side 231111. Each first arc surface 23111 gradually bends and extends away from the impeller body 221 from the first head side 231111 to the first tail side 231112. The first arc surfaces 23111 can be used to change the bending radius of each blade 222 when the impeller body 221 rotates, gradually increasing the bending radius of each blade 222, thereby increasing the volume of each chamber 211. This allows for the absorption of gaseous or liquid media. Similarly, referring to the bending method of each first arc surface 23111, each second arc surface 23112 can be in the opposite direction to the bending direction of the first arc surface 23111. Specifically, as shown... Figure 5 and Figure 6 As shown, the rotation direction of each second arc surface 23112 around the impeller 22 includes the second head side 231121 and the second tail side 231122 away from the second head side 231121. Each second arc surface 23112 gradually bends and extends from the second head side 231121 to the second tail side 231122 towards the impeller body 221. Each second arc surface 23112 can be used to change the bending radius of each blade 222 when the impeller body 221 rotates, so that the bending radius of each blade 222 gradually decreases, thereby reducing the volume of each chamber 211. At this time, the gas or liquid medium that has been sucked can be pumped out into the mixing chamber 122 of the medium mixing component 1.

[0054] Furthermore, in some embodiments, such as Figure 5 and Figure 6As shown, each first arc surface 23111 and each second arc surface 23112 are arranged alternately and connected around a preset axis. That is, the first head side 231111 of any first arc surface 23111 can be connected to the second tail side 231122 of one of the adjacent second arc surfaces 23112, so that the first arc surface 23111 and the second arc surface 23112 can form an arc-shaped protrusion. At the same time, the first tail side 231112 of the first arc surface 23111 can be connected to the second head side 231121 of another adjacent second arc surface 23112, so that the first arc surface 23111 and the other second arc surface 23111 can form an arc-shaped depression. It is easy to see that when the impeller 22 is rotating, if any chamber 211 is opposite to the arc-shaped protrusion, the volume of the chamber 211 is at its minimum and positive pressure is generated. When any chamber 211 is opposite to the arc-shaped depression, the volume of the chamber 211 is at its maximum and negative pressure is generated.

[0055] Furthermore, it is not difficult to see from the above embodiment 1 that since there are four media discharge holes 112 and four media inlet holes 111 respectively, there are four media discharge holes 112 and four media inlet holes 111 respectively. In other embodiments, such as Figure 5 and Figure 6 As shown, the cavity 21 and the impeller 22 can also be coaxially arranged along a preset axis. Furthermore, there are four first arc surfaces 23111 and four second arc surfaces 23112, and corresponding to the number of first arc surfaces 23111 and second arc surfaces 23112, there are a total of eight blades 222. Each blade 222 can be equidistantly arranged around the outer surface 2211 of the impeller body 221. Simultaneously, each medium discharge hole 112 and each medium inlet hole 111 can be equidistantly arranged around the base plate 11 along the preset axis, and the medium discharge holes 112 and each medium inlet hole 111 alternate sequentially. For example... Figure 5 and Figure 6 As shown, four media discharge holes 112 are uniquely configured to correspond to each arc-shaped recess and are connected to each cavity 1211, so that each media discharge hole 112 can generate negative pressure when the volume of the corresponding cavity 211 increases, thereby completing the absorption of gas and liquid media. Similarly, four media inlet holes 111 are uniquely configured to correspond to each arc-shaped protrusion and are connected to each mixing cavity 122, so that each media inlet hole 111 can generate positive pressure when the volume of the corresponding cavity 211 decreases, thereby pumping the absorbed liquid and gas media into the mixing cavity 122, completing the mixing of gas and liquid media.
