Abstract

This application discloses a liquid dispensing device and system, relating to, but not limited to, liquid dispensing technology. The liquid dispensing device includes a housing, a filtering component, an accelerating component, and a constant flow component. The housing includes a circumferential wall and a liquid dispensing component. The filtering component is disposed upstream of the circumferential wall. The accelerating component has an annular wall that fits against the circumferential wall. The annular wall, in cooperation with the circumferential wall, restricts the radial movement of the accelerating component along the circumferential wall and restricts the oscillation of the accelerating component relative to the circumferential wall. The constant flow component is disposed upstream of the circumferential wall and partially abuts against the liquid dispensing component. The cooperation between the constant flow component and the liquid dispensing component restricts the axial movement of the accelerating component relative to the circumferential wall. Thus, the cooperation of the circumferential wall, the constant flow component, and the liquid dispensing component fixes the accelerating component, thereby avoiding the formation of an unformable connection structure within the cavity and ensuring the stability of the connection between the accelerating component and the circumferential wall.

Description

Technical Field

[0001] This application relates to, but is not limited to, liquid dispensing technology, and particularly to a liquid dispensing device and system. Background Technology

[0002] Existing liquid dispensing devices generally consist of a housing and functional components housed within the housing. To maintain a constant relative position between the functional components and the housing, a connection structure is required between the functional components and the housing in the circumferential direction.

[0003] With the continuous development of liquid dispensing technology and the increasing demand for water conservation, people are increasingly focusing on miniaturizing liquid dispensing devices (outer diameter smaller than 10 mm). The demand for liquid dispensing devices is becoming increasingly strong. However, miniaturized liquid dispensing devices are prone to manufacturing problems such as difficult-to-form structures (e.g., relatively smaller connection structures) or easy deformation after forming, which can easily lead to connection failures between structures and cause the liquid dispensing device to malfunction. Summary of the Invention

[0004] This application provides a liquid dispensing device and a liquid dispensing system, which aims to solve the technical problem that connection failures between structures are prone to occur in existing miniaturized liquid dispensing devices, causing the liquid dispensing device to malfunction.

[0005] To achieve the above objectives, this application provides a liquid dispensing device, comprising:

[0006] The housing includes a circumferential wall and a liquid outlet component, the liquid outlet component being disposed on the downstream side of the circumferential wall, the circumferential wall and the liquid outlet component forming an inner cavity, and an air inlet space being provided on the circumferential wall;

[0007] A filter element is disposed on the upstream side of the circumferential wall and is configured to filter the liquid entering the inner cavity;

[0008] An accelerating component is installed in the inner cavity. The accelerating component has an annular wall that fits against the circumferential wall. A mixing chamber is provided between the accelerating component and the liquid outlet component. The air inlet space communicates with the mixing chamber. The accelerating component is configured to accelerate the liquid towards the liquid outlet component and create a negative pressure in the mixing chamber, drawing in air to mix with the liquid.

[0009] A constant flow component is disposed on the upstream side of the circumferential wall and abuts a portion of the acceleration component against the liquid outlet component. The constant flow component is configured to limit the liquid flow rate from the filter component to the acceleration component.

[0010] To achieve the above objectives, this application also provides a liquid dispensing system, comprising:

[0011] The liquid dispensing device as described above; and

[0012] The liquid supply device is configured to supply liquid to the upstream side.

[0013] Implementing the embodiments of this application will have the following beneficial effects:

[0014] The liquid dispensing device described above is used in a liquid dispensing system. Besides improving the system's dispensing efficiency, it also avoids the use of difficult-to-form structures, enhances the stability of connections between structures, and prevents malfunctions. Specifically, the liquid dispensing device includes a housing, a filter component, an acceleration component, and a constant flow component. The housing includes a circumferential wall and a liquid dispensing component located downstream of the circumferential wall, forming an inner cavity with the wall. The filter component is located upstream of the circumferential wall and is configured to filter the liquid entering the inner cavity, removing large particulate impurities. The accelerating component has an annular wall that fits against the circumferential wall. The annular wall, in conjunction with the circumferential wall, restricts the radial movement of the accelerating component along the circumferential wall and limits its relative oscillation. A constant flow component is positioned upstream of the circumferential wall, with a portion of the accelerating component abutting against the liquid outlet component. The cooperation between the constant flow component and the liquid outlet component restricts the axial movement of the accelerating component relative to the circumferential wall. Thus, the cooperation of the circumferential wall, the constant flow component, and the liquid outlet component fixes the accelerating component, preventing the formation of difficult-to-form connection structures within the inner cavity and ensuring the stability of the connection between the accelerating component and the circumferential wall. The constant flow component is configured to limit the liquid flow from the filtering component to the accelerating component, achieving a throttling effect. A mixing chamber is provided between the accelerating component and the liquid outlet component, and the air inlet space communicates with the mixing chamber. The accelerating component is configured to accelerate the liquid towards the liquid outlet component and create negative pressure in the mixing chamber, drawing in air to mix with the liquid, forming a water-air mixture that is discharged downstream through the liquid outlet component.

[0055] Existing liquid dispensing devices generally consist of a housing and multiple functional components housed within the housing. To maintain the relative positions of the functional components and the housing, a connection structure is required between the functional components and the housing in the circumferential direction.

[0056] With the continuous development of liquid dispensing technology and the increasing demand for water conservation, people are increasingly focusing on miniaturizing liquid dispensing devices (outer diameter smaller than 10 mm). The demand for liquid dispensing devices is becoming increasingly strong. However, miniaturized liquid dispensing devices are prone to manufacturing problems such as difficult-to-form structures (e.g., relatively smaller connection structures) or easy deformation after forming, which can easily lead to connection failures between structures and cause the liquid dispensing device to malfunction.

[0057] To address the aforementioned technical problems, this application provides a liquid dispensing device and system. This system can be installed in various environments such as companies, schools, homes, and factories to achieve cleaning effects, thereby improving people's quality of life and health. The liquid dispensing system can be, but is not limited to, one or more combinations of a faucet, showerhead, overhead sprayer, and spray gun. For ease of description, a faucet will be used as an example of the liquid dispensing system below.

[0058] Please combine them together Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 10 , Figure 12 , Figure 15 , Figures 16 to 27 , Figures 29 to 31 The liquid dispensing system provided in this application embodiment will now be described. The liquid dispensing system includes a liquid dispensing device and a liquid supply device. The liquid dispensing device includes a housing 10, a filter component 20, an acceleration component 30, and a constant flow component 40. The housing 10 includes a circumferential wall 11 and a liquid dispensing component 12, which is disposed downstream of the circumferential wall 111. The circumferential wall 11 and the liquid dispensing component 12 together form an inner cavity 100, and an air inlet space 101 is provided on the circumferential wall 11. The filter component 20 is disposed upstream of the circumferential wall 112 and is configured to filter the liquid entering the inner cavity 100. An accelerating component 30 is installed in the inner cavity 100. The accelerating component 30 has an annular wall 31 that fits against the circumferential wall 11. A mixing chamber 102 is provided between the accelerating component 30 and the liquid outlet component 12. The air inlet space 101 communicates with the mixing chamber 102. The accelerating component 30 is configured to accelerate the liquid towards the liquid outlet component 12 and create a negative pressure in the mixing chamber 102, drawing in air to mix with the liquid. A constant flow component 40 is disposed on the upstream side 112 of the circumferential wall 11 and a portion of the accelerating component 30 abuts against the liquid outlet component 12. The constant flow component 40 is configured to limit the liquid flow rate from the filter component 20 to the accelerating component 30.

[0059] The dispensing device also includes a housing assembly 50. The housing assembly 50 is fitted onto the housing 10 and has a fastening part 511 configured to secure the dispensing device to an external structure. In this embodiment, the external structure is a faucet body 0. The fastening part 511 has external threads, which can connect with internal threads on the faucet body 0, allowing the dispensing device to be partially exposed or completely concealed within the faucet body 0. It can be understood that in other embodiments, the fastening part 511 can also be connected to the faucet body 0 by means of, but not limited to, snap-fit, plug-in, or welding. Furthermore, in some embodiments, such as... Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown, the liquid dispensing device may also be without the outer casing assembly 50, and the casing 10 may be directly connected to the faucet body 0.

[0060] The liquid supply device is configured to supply liquid to the upstream side 112. The liquid supply device may have, but is not limited to, a valve structure with manual or electric control. By opening or closing the liquid supply device, the upstream side 112 is connected or disconnected from the liquid source via the faucet body 0. The liquid includes, but is not limited to, clean water or pure water from the municipal water network.

[0061] In summary, implementing the embodiments of this application will have the following beneficial effects: the liquid dispensing device described above, when applied to a liquid dispensing system, not only achieves the liquid dispensing efficiency of the system, but also avoids the use of structures that are difficult to form, improves the connection stability between structures, and prevents the liquid dispensing device from malfunctioning. Specifically, the liquid dispensing device includes a housing 10, a filter component 20, an acceleration component 30, and a constant flow component 40. The housing 10 includes a circumferential wall 11 and a liquid dispensing component 12 disposed on the downstream side 111 of the circumferential wall 11, which together with the circumferential wall 11 forms an inner cavity 100. The filter component 20 is disposed on the upstream side 112 of the circumferential wall 11 and is configured to filter the liquid entering the inner cavity 100 to remove large particulate impurities from the liquid. The accelerating component 30 has an annular wall 31 that fits against the circumferential wall 11. The annular wall 31, in cooperation with the circumferential wall 11, restricts the radial movement of the accelerating component 30 along the circumferential wall 11 and limits its oscillation relative to the circumferential wall 11. A constant flow component 40 is disposed on the upstream side 112 of the circumferential wall 11, and a portion of the accelerating component 30 abuts against the liquid outlet component 12. The cooperation between the constant flow component 40 and the liquid outlet component 12 restricts the axial movement of the accelerating component 30 relative to the circumferential wall 11. Thus, the cooperation of the circumferential wall 11, the constant flow component 40, and the liquid outlet component 12 fixes the accelerating component 30, preventing the formation of an unformable connection structure within the inner cavity 100 and ensuring the stability of the connection between the accelerating component 30 and the circumferential wall 11. The constant flow component 40 is configured to limit the liquid flow from the filter component 20 to the accelerating component 30, thereby achieving a throttling effect. A mixing chamber 102 is provided between the accelerating component 30 and the liquid outlet component 12. The air inlet space 101 is connected to the mixing chamber 102. The accelerating component 30 is configured to accelerate the liquid towards the liquid outlet component 12 and create a negative pressure in the mixing chamber 102, drawing in air and mixing it with the liquid to form a water-air mixture that is discharged from the downstream side 111 through the liquid outlet component 12.

[0062] In one exemplary embodiment, please refer to Figure 7 , Figure 9 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 , Figure 26 , Figure 30 and Figure 31The accelerating component 30 is provided with a first connecting portion 32, and the constant flow component 40 is provided with a second connecting portion 41. The first connecting portion 32 and the second connecting portion 41 are connected, and the accelerating component 30 and the constant flow component 40 are spaced apart to form a throttling cavity 103. The arrangement of the first connecting portion 32 and the second connecting portion 41 forms the throttling cavity 103, allowing the liquid to be evenly distributed within the accelerating component 30 after entering the throttling cavity 103, facilitating the acceleration of the liquid by the accelerating component 30. The size of the throttling cavity 103 along the liquid flow direction ranges from 1 mm to 10 mm. For example, in this embodiment, the accelerating component 30 and the constant flow component 40 are parallel to each other, and the size of the throttling cavity 103 along the liquid flow direction can be from 1.3 mm to 2 mm. The fact that the size of the throttling cavity 103 along the liquid flow direction is within the aforementioned range further ensures that the liquid entering the throttling cavity 103 is evenly distributed in the accelerating component 30. This allows the liquid to be replenished immediately after being accelerated by the accelerating component 30, resulting in uniform liquid discharge from the accelerating component 30 and ensuring that the liquid discharge from the dispensing device is full and does not constrict. However, if the size of the throttling cavity 103 along the liquid flow direction is larger than the aforementioned range, it will affect the miniaturization of the dispensing device.

[0063] Meanwhile, the connection between the first connecting part 32 and the second connecting part 41 can also transmit the resisting force generated by the constant current component 40 to the acceleration component 30 through the second connecting part 41 and the first connecting part 32.

[0064] In one exemplary embodiment, please refer to Figure 7 , Figure 9 , Figure 18 , Figure 19 , Figure 21 and Figure 22 The first connecting part 32 and the second connecting part 41 are integrally formed. This reduces the number of parts of the liquid dispensing device while ensuring that the function of the liquid dispensing device remains unchanged, simplifies the assembly process, facilitates the rapid assembly of the liquid dispensing device, avoids the separation of the accelerating component 30 and the constant flow component 40 during use, and further improves the connection stability between the accelerating component 30 and the circumferential wall 11.

[0065] Furthermore, in some embodiments, please combine Figure 25 , Figure 26 , Figure 30 and Figure 31 The first connecting part 32 and the second connecting part 41 can also be connected separately to facilitate changing the type of the accelerating component 30 and the constant current component 40, as well as performing individual maintenance or replacement. For example... Figure 25 and Figure 26 As shown, the first connecting part 32 and the second connecting part 41 are inserted into each other. One of the first connecting part 32 and the second connecting part 41 has a insertion hole, and the other is inserted into the insertion hole to achieve connection and positioning between the first connecting part 32 and the second connecting part 41. Figure 30 and Figure 31 The first connecting portion 32 abuts against the second connecting portion 41. The first connecting portion 32 and the second connecting portion 41 are connected by abutting planes that fit together. The abutting planes have a dimension that extends radially along the circumferential wall 11 to ensure the stability of the abutting connection between the first connecting portion 32 and the second connecting portion 41.

[0066] In one exemplary embodiment, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 9 , Figure 13 , Figure 16 , Figure 18 , Figure 19 , Figures 21 to 23 , Figures 25 to 27 and Figures 30 to 32 The constant flow component 40 includes a flow-through component 42 and an elastic component 43. The flow-through component 42 has a flow-through orifice 200. The flow-through orifice 200 connects the filter component 20 and the acceleration component 30. The elastic component 43 is configured to elastically deform under liquid pressure to control the cross-sectional area of ​​the liquid entering the flow-through orifice 200. Thus, as the liquid pressure changes, the elastic deformation of the elastic component 43 changes accordingly, thereby altering the cross-sectional area of ​​the liquid in real time, achieving precise flow throttling, and ultimately meeting the constant flow rate requirement of the liquid outlet device. The elastic component 43 is made of an elastomer material.

[0067] In one exemplary embodiment, please refer to Figure 3 , Figure 7 , Figure 9 , Figure 13 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 and Figure 26 The flow-through component 42 is provided with a positioning structure 421, and the elastic component 43 is positioned and installed on the positioning structure 421. In this way, the positioning structure 421 can prevent the elastic component 43 from moving out of the working position during operation, thus affecting the throttling effect.

[0068] In one exemplary embodiment, please refer to Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 13 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 and Figure 26The positioning structure 421 has a groove 300. The flow hole 200 communicates with the groove 300. The elastic element 43 is positioned and installed in the groove 300. Thus, the groove 300 increases the connection area between the positioning structure 421 and the elastic element 43, improving connection stability. It can be understood that in other embodiments, the positioning structure 421 can also achieve positioning through snap-fit ​​or other methods.

[0069] The positioning structure 421 surrounds the groove 300, forming a groove wall with an anti-clogging protrusion 422. The anti-clogging protrusion 422 is configured to ensure that a gap 301 is formed between the elastic element 43 and the groove wall, communicating with the flow hole 200. Thus, the anti-clogging protrusion 422 prevents the elastic element 43 from elastically deforming and completely blocking the flow hole 200, ensuring constant communication between the filter component 20 and the flow hole 200. The side of the anti-clogging protrusion 422 facing the elastic element 43 has an arc surface to prevent cutting the elastic element 43. In this embodiment, the elastic element 43 is annular, the groove 300 is an annular groove, and the number of flow holes 200 is multiple and evenly distributed along the circumference of the annular groove. The multiple flow holes 200 can be disposed on the bottom and / or wall of the annular groove. The number of anti-blocking protrusions 422 is multiple and evenly distributed along the circumference of the annular groove. The gaps 301 formed are connected to at least one flow hole 200 to ensure the anti-blocking effect of each flow hole 200.

[0070] like Figure 28 As shown, to further ensure the connection stability between the elastic element 43 and the positioning structure 421, multiple limiting protrusions 423 are provided on the groove wall to prevent the elastic element 43 from falling out of the groove 300 during use. The elastic element 43 can be installed in the groove 300 by elastically deforming over the limiting protrusions 423.

[0071] In other embodiments, the elastic element 43 may also be a block structure, and there may be multiple elastic elements 43. Correspondingly, there may be multiple grooves 300, with each elastic element 43 installed in one of the multiple grooves 300. Each groove 300 is in communication with at least one flow hole 200.

[0072] In one exemplary embodiment, please refer to Figures 30 to 32The flow-through component 42 has a flow-rectifying surface 424 on the side facing the filter component 20, and a flow-rectifying groove 400 communicating with the flow-through hole 200 is provided on the flow-rectifying surface 424. An elastic component 43 is fitted over the flow-rectifying surface 424 so that it can partially conform to the flow-rectifying surface 424 after elastic deformation. The elastic component 43 can partially extend into the flow-rectifying groove 400 to limit the cross-sectional area of ​​the liquid flow. A through hole 500 is provided on the elastic component 43, which connects the filter component 20 and the flow-rectifying groove 400. In this embodiment, the elastic component 43 is a diaphragm structure with the through hole 500. Without liquid pressure, the elastic component 43 is spaced apart from the flow-rectifying surface 424. Under liquid pressure, the elastic component 43 undergoes elastic deformation and deflects towards the flow-rectifying surface 424 to partially conform to it, thereby controlling the cross-sectional area of ​​the liquid entering the flow-through hole 200. A plurality of rectifying parts 4241 are provided on the rectifying surface 424, and the plurality of rectifying parts 4241 are spaced apart to form a plurality of rectifying slots 400. One end of each rectifying slot 400 faces the orthogonal projection position of the hole wall of the through hole 500 on the rectifying surface 424, and the other end is connected to the flow hole 200.

[0073] In one exemplary embodiment, such as Figure 32 As shown, a limiting portion 4242 is provided on the rectifying surface 424. The limiting portion 4242 is configured to prevent the elastic member 43 from disconnecting the through hole 500 from the flow hole 200. Thus, the limiting portion 4242 prevents excessive elastic deformation of the elastic member 43, which could cause the through hole 500 to disconnect from the flow hole 200. The limiting portion 4242 is located on the deformation path of the elastic member 43 under liquid pressure. In this embodiment, multiple limiting portions 4242 are provided around the rectifying surface 424, and the filter component 20 can clamp the elastic member 43 on the limiting portion 4242 to ensure the stability of the elastic member 43 during use.

[0074] In one exemplary embodiment, please refer to Figure 7 , Figure 9 , Figure 18 , Figure 19 , Figure 25 and Figure 26 The filter element 20 is provided with a support portion 21. The support portion 21 is located in the middle of the filter element 20 to increase the strength of the filter element 20 and improve its performance against liquid impact. The flow-through element 42 is provided with a positioning groove 600 to position and connect the flow-through element 42 with the support portion 21, further improving the performance of the filter element 20 against liquid impact. At the same time, the provision of the support portion 21 allows the filter element 20 and the flow-through element 42 to be spaced apart to form a liquid inlet chamber 104.

[0075] In one exemplary embodiment, please refer to Figure 12 , Figures 15 to 27 and Figures 29 to 31 The elastic element 43 is disposed on the filter component 20, the constant flow component 40, or the housing assembly 50 to further reduce the number of parts in the liquid dispensing assembly, simplify the assembly process, and facilitate the rapid assembly of the liquid dispensing device. Simultaneously, it further improves the positional stability of the elastic element 43. In this embodiment, the housing assembly 50 includes a connecting sleeve 51 and a sealing element 52. The connecting sleeve 51 is fitted onto the housing 10. A fastening part 511 is disposed on the connecting sleeve 51. The connecting sleeve 51 extends to the downstream side 111 and forms an air intake channel 105 communicating with the air intake space 101 between the connecting sleeve 51 and the housing 10. The sealing element 52 is fitted onto the housing 10 to prevent liquid from flowing into the housing assembly 50 between it and an external structure (such as the faucet body 0). After the constant flow component 40 is connected to the circumferential wall 11, it can form a snap-fit ​​structure 425 that engages with the sealing element 52. After the sealing element 52 engages with the snap-fit ​​structure 425, it is fitted onto the circumferential wall 11. Figure 18 , Figure 19 , Figure 25 , Figure 26 , Figure 30 and Figure 31 As shown, the filter element 20 can pass through the seal 52 and be snapped onto the constant flow element 40, or, as... Figure 21 and Figure 22 As shown, the sealing element 52 is sleeved on the filter element 20, so that the sealing element 52 can be sleeved on the circumferential wall 11, the constant flow element 40, and the filter element 20 respectively. The external structure can elastically abut against the circumferential wall 11, the constant flow element 40, and the filter element 20 through the sealing element 52, so as to ensure the connection stability between the housing 10, the constant flow element 40, and the filter element 20. Figure 21 and Figure 22 As shown, the elastic element 43 is disposed on the sealing element 52. After the sealing element 52 is engaged with the snap-fit ​​structure 425, it is sleeved on the circumferential wall 11, and the elastic element 43 is received in the groove 300.

[0076] In one exemplary embodiment, please refer to Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 10 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 , Figure 26 , Figure 30 and Figure 31The constant current component 40 is engaged with the circumferential wall 11. One of the constant current component 40 and the circumferential wall 11 has an annular groove 700, and the other has a engaging protrusion 426 that mates with the annular groove 700. The engaging protrusion 426 has an arcuate surface. In this embodiment, the engaging protrusion 426 is disposed on the constant current component 40, and the annular groove 700 is disposed on the circumferential wall 11. The circumferential wall 11 also has an arcuate surface to facilitate the engaging protrusion 426 into the annular groove 700. The constant current component 40 is provided with a first anti-rotation portion 427. The circumferential wall 11 is provided with a second anti-rotation portion 113 that is connected to the first anti-rotation portion 427 to prevent rotation. The first anti-rotation portion 427 and the second anti-rotation portion 113 cooperate to achieve an anti-rotation connection between the constant current component 40 and the circumferential wall 11, while also serving a positioning function. One of the first anti-rotation part 427 and the second anti-rotation part 113 has an anti-rotation groove, and the other is an anti-rotation protrusion that can be accommodated in the anti-rotation groove.

[0077] In one exemplary embodiment, please refer to Figure 3 , Figure 5 , Figures 7 to 9 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 , Figure 26 , Figure 30 and Figure 31 The accelerating component 30 is provided with multiple accelerating holes 800 to accelerate the liquid passing through it. The multiple accelerating holes 800 can accelerate the liquid into multiple fine liquid columns, facilitating liquid acceleration. Simultaneously, it increases the contact area between the liquid and air, improving the mixing effect between the air and liquid.

[0078] In one exemplary embodiment, please refer to Figure 3 , Figure 5 , Figures 7 to 9 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 , Figure 26 , Figure 30 and Figure 31The accelerating orifice 800 has an accelerating section 801 near the upstream side 112 and a diffusing section 802 near the downstream side 111. The diffusing section 802 has a small end communicating with the accelerating section 801 and a large end near the downstream side 111. By utilizing the small radial dimension of the accelerating section 801, the liquid can be rapidly accelerated; while utilizing the large end of the diffusing section 802, the liquid outlet angle of the diffusing section 802 can be made larger, which is beneficial for the liquid to diffuse into the mixing chamber 102, further increasing the contact area between the liquid and air and improving the mixing effect of air and liquid. The dimension of the accelerating section 801 along the liquid flow direction is larger than the dimension of the diffusing section 802 along the liquid flow direction, thus ensuring that the liquid has a certain acceleration distance and guaranteeing the acceleration effect of the accelerating component 30.

[0079] In one exemplary embodiment, please refer to Figures 7 to 11 , Figure 14 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 25 , Figure 26 , Figure 30 and Figure 31 The liquid outlet component 12 includes a collapsible component 121, which is integrally formed with the circumferential wall 11. This reduces the number of parts, simplifies the assembly process, facilitates the rapid assembly of the liquid outlet device, prevents the collapsible component 121 from separating from the circumferential wall 11 during use, and further improves the connection stability between the collapsible component 121 and the circumferential wall 11.

[0080] The collapsible element 121 is configured to block the liquid that is accelerated towards the liquid outlet component 12, so that the liquid is discharged from the downstream side 111 after collapsing. Due to the blocking effect of the collapsible element 121, the high-speed liquid can be collapsing after impacting the collapsible element 121, achieving an atomization effect, further increasing the contact area between air and liquid, improving the mixing effect between air and liquid, and making the mixing of air and liquid more complete, so as to ensure the air content in the liquid discharged from the downstream side 111, thereby ensuring the liquid discharge effect.

[0081] In one exemplary embodiment, please refer to Figure 4 , Figure 7 , Figure 9 , Figure 10 , Figure 16 , Figure 18 , Figure 19 , Figure 21 , Figure 22 , Figure 23 , Figure 25 , Figure 26 , Figure 30 and Figure 31One of the accelerating component 30 and the collapsing component 121 is provided with an abutting post 33, and the other is provided with an abutting part 1211. Under the drive of the constant current component 40, the abutting post 33 abuts against the abutting part 1211, so that a mixing cavity 102 is formed between the accelerating component 30 and the collapsing component 121.

[0082] In one exemplary embodiment, please refer to Figure 8 , Figure 10 , Figure 11 and Figure 14 The collapsing component 121 includes multiple collapsing structures 1212, each corresponding to a plurality of accelerating holes 800. The collapsing structures 1212 and their corresponding accelerating holes 800 are at least partially opposite each other along the liquid flow direction. By configuring one collapsing structure 1212 for each accelerating hole 800, the liquid collapsing effect can be further guaranteed, the atomization effect improved, the mixing effect between air and liquid further enhanced, the gas-liquid mixing ratio increased, and the liquid output effect guaranteed. A liquid passage 900 is formed between adjacent collapsing structures 1212 to connect the mixing chamber 102 to the downstream side 111, allowing the atomized water-air mixture to be discharged from the downstream side 111 through the liquid passage 900.

[0083] In one exemplary embodiment, please refer to Figure 8 , Figure 11 and Figure 14 The collapsing structure 1212 includes a wave section, which comprises a crest section 12121 and a trough section 12122 connected in sequence. The crest section 12121 protrudes towards the accelerating component 30, and the trough section 12122 is recessed away from the accelerating component 30. The crest section 12121 or the trough section 12122 is at least partially opposite to the corresponding accelerating hole 800 along the liquid flow direction. In this embodiment, the crest section 12121 and the corresponding accelerating hole 800 are at least partially opposite along the liquid flow direction. After the liquid accelerates and impacts the crest section 12121, it will impact the trough section 12122 at least multiple times, allowing the liquid to collapse multiple times and further improving the atomization effect. It can be understood that in other embodiments, the trough section 12122 and the corresponding accelerating hole 800 are at least partially opposite along the liquid flow direction. After the liquid accelerates and impacts the trough section 12122, it will impact the trough section 12122 at least multiple times again, allowing the liquid to collapse multiple times and further improving the atomization effect.

[0084] In one exemplary embodiment, please refer to Figure 8 , Figure 11 and Figure 14A collapsing protrusion 12123 is provided on the side of the crest section 12121 or trough section 12122 facing the acceleration hole 800. The collapsing protrusion 12123 and the corresponding acceleration hole 800 are arranged opposite each other along the liquid flow direction, and the side of the collapsing protrusion 12123 facing the acceleration hole 800 is spherical. Accelerating the liquid impacts the collapsing protrusion 12123, which can more evenly disperse the liquid to the surrounding area, further improving the dispersion effect. In this embodiment, the collapsing protrusion 12123 is provided on the crest section 12121. When the liquid accelerates and impacts the collapsing protrusion 12123, some of the liquid will impact the crest section 12121 and trough section 12122 at least multiple times after dispersion, while other liquid will impact other dispersion structures 1212 and disperse again. In other embodiments, the collapsing protrusion 12123 can also be located in the trough section 12122. The liquid accelerates and impacts the collapsing protrusion 12123, causing some of the liquid to collide with the trough section 12122 multiple times after collapsing. Another portion of the liquid will impact other collapsing structures 1212 and collide again. This allows the liquid to mix more thoroughly with air after passing through the collapsing component 121, resulting in better atomization and further ensuring the air content in the liquid discharged from the downstream side 111, thus guaranteeing the liquid discharge effect.

[0085] In one exemplary embodiment, please refer to Figure 11 and Figure 14 The collapse structure 1212 also includes a reinforcing portion 12124, which is disposed on the wave portion corresponding to the collapse protrusion 12123. The reinforcing portion 12124 increases the strength of the location of the collapse protrusion 12123, improving the wave portion's resistance to liquid impact. In this embodiment, two reinforcing portions 12124 are disposed corresponding to the location of the collapse protrusion 12123, respectively disposed on both sides of the wave portion and located within the liquid passages 900 on both sides of the wave portion.

[0086] In one exemplary embodiment, please refer to Figure 11 and Figure 14 The reinforcing portion 12124 extends along the liquid flow direction, and the side of the reinforcing portion 12124 facing the acceleration hole 800 has a passivated surface 121241. This allows the reinforcing portion 12124 to guide the liquid to facilitate the liquid passing through the liquid passage 900.

[0087] In one exemplary embodiment, please refer to Figure 10 , Figure 11 and Figure 14 The collapsible component 121 also includes a connecting wall 1213, which is provided between two adjacent wave sections. This can further improve the strength of the wave section and further improve its resistance to liquid impact.

[0088] In the embodiments of this application, please refer to the following: Figures 2 to 5 , Figure 10 , Figure 11 and Figure 14 Multiple acceleration holes 800 are arranged in a double-ring pattern. Correspondingly, multiple collapsing structures 1212 are also arranged in a double-ring pattern with multiple acceleration holes 800. To ensure that the strength of each collapsing structure 1212 is similar and to ensure the stability of the liquid outlet shape, multiple connecting walls 1213 are also distributed in a certain regular pattern. For example, in the embodiment of this application, multiple connecting walls 1213 are arranged in a double-ring pattern.

[0089] In one exemplary embodiment, please refer to Figure 4 , Figure 6 , Figure 7 , Figure 9 , Figure 11 , Figures 17 to 22 , Figures 24 to 26 and Figures 29 to 31 The liquid dispensing component 12 also includes a grid plate 122, which is installed in the inner cavity 100 and integrally formed with the circumferential wall 11. This reduces the number of parts, simplifies the assembly process, facilitates the rapid assembly of the liquid dispensing device, avoids the separation of the grid plate 122 from the circumferential wall 11 during use, and further improves the connection stability between the grid plate 122 and the circumferential wall 11.

[0090] The grid plate 122 is configured to rectify the liquid passing through the collapsing structure 1212 so that the rectified liquid is discharged from the downstream side 111. After being rectified by the grid plate 122, the liquid is discharged from the downstream side 111 through the grid holes on the grid plate 122, forming a round and full milky white bubble liquid column.
