[0056] In addition, when describing representative embodiments, the specification may have presented the method and / or process as a specific sequence of steps. However, to the extent that the method or process does not rely on the specific order of the disclosed steps, the method or process should not be limited to the steps in the specific order.

[0057] The liquid discharge device is generally made of all-copper casting or stainless steel welding. The material cost of all-copper casting and stainless steel welding is high, and the processing and production process is complicated, resulting in high costs for the liquid discharge device. In addition, the all-copper casting product has a high lead content, and stainless steel welding has welding slag and solder, which seriously affects the quality of the liquid discharged from the liquid discharge device.

[0058] At present, injection molding structures are often used to replace the structures in the liquid discharge device to reduce or avoid the use of all-copper casting structures or stainless steel welding structures, reduce the cost of the liquid discharge device, and improve the quality of the liquid discharged. Injection molding structures generally have core pulling holes for core pulling, and the core pulling holes are blocked by plugging parts. The plugging parts and injection molding structures are generally connected by threads or metal inserts, which requires secondary processing or more complex injection mold molding of the injection molding structure, affecting the injection molding production efficiency.

[0059] The embodiments of the present disclosure provide a liquid discharge mechanism and a liquid discharge device, which can be installed in various occasions and environments such as companies, schools, homes, and factories to enhance and improve people's quality of life and health. The liquid discharge device can supply liquid to, but is not limited to, one or more combinations of faucets, showers, overhead sprays, and spray guns. To facilitate the description of the technical solution of the present disclosure, the following is an example of a liquid discharge device supplying liquid to a faucet, shower, and overhead spray. The liquid includes, but is not limited to, clean water or pure water from a municipal water network.

[0060] Please combine Figures 1 to 5 , Fig. 9 and Figures 11 to 13 The liquid outlet device provided in the embodiment of the present disclosure is now described. The liquid outlet device includes a liquid outlet mechanism 10, a liquid separation mechanism 20 and a communication mechanism 30.

[0061] The liquid outlet mechanism 10 includes a housing 11, an injection molded part 12 and a control component 13. The housing 11 is provided with an installation space 100. The housing 11 may be a metal structure or an injection molded structure. One end of the installation space 100 has an opening, which is generally arranged on the side of the housing 11 facing the installation position. For example, the opening may be arranged facing the wall to be away from the user's observation side. The setting of the opening can facilitate the installation of the injection molded part 12, and facilitate the disassembly and maintenance of the injection molded part 12.

[0062] The injection molded part 12 is provided with a core-pulling hole 200 and a first flow channel 300 that are interconnected. The core-pulling hole 200 facilitates the core-pulling of the injection molded part 12 after injection molding, so that the injection molded part 12 can be integrally molded, avoiding secondary connection molding, and ensuring the strength of the injection molded part 12 and the sealing performance of the first flow channel 300. The first flow channel 300 is configured to allow liquid to be discharged. Under the limitation of the first flow channel 300, the liquid entering the first flow channel 300 can flow along the first flow channel 300 and be discharged.

[0063] The core pulling hole 200 is provided with a sealing piece 14. When the injection molded part 12 is installed on the shell 11, the shell 11 can abut against the sealing piece 14, and the core pulling hole 200 is sealed by the sealing piece 14 to ensure the sealing of the core pulling hole 200 and prevent liquid from being discharged from the core pulling hole 200.

[0064] The control component 13 is disposed on the housing 11. The control component 13 is configured to control the connection or disconnection of the first flow channel 300. When the first flow channel 300 is connected, the liquid can smoothly pass through the first flow channel 300; when the first flow channel 300 is disconnected, the liquid is blocked and cannot pass through the first flow channel 300. The control component 13 can be partially moved into the first flow channel 300 and moved out of the first flow channel 300, thereby controlling the connection or disconnection of the first flow channel 300. In addition, the first flow channel 300 can be connected through the connecting cavity 400, such as Figure 3 , Fig. 9 and Fig.13 As shown, the control assembly 13 can be partially moved into and out of the communication chamber 400, thereby controlling the connection or disconnection of the first flow channel 300. The communication chamber 400 can be located at the liquid inlet position, the liquid outlet position, or between the liquid inlet position and the liquid outlet position of the first flow channel 300 to connect the first flow channel 300.

[0065] The first flow channel 300 includes a liquid inlet end 301 and a liquid outlet end 302 that are interconnected. The liquid separation mechanism 20 is disposed on the liquid outlet mechanism 10. The liquid separation mechanism 20 is provided with a liquid inlet flow channel 500 and a plurality of liquid outlet flow channels, and the liquid inlet flow channel 500 is connected to the first flow channel 300. The liquid separation mechanism 20 is configured to selectively connect the liquid inlet flow channel 500 with at least one liquid outlet flow channel. The connecting mechanism 30 is connected between the liquid outlet end 302 and one of the liquid outlet flow channels, and disconnects the liquid inlet end 301 from the liquid outlet end 302, so that after the liquid enters the first flow channel 300, it does not directly enter the liquid outlet end 302, but needs to pass through the liquid inlet flow channel 500, and under the selective action of the liquid separation mechanism 20, enters the liquid outlet end 302 from the liquid outlet flow channel connected to the liquid outlet end 302 and is discharged, as shown in FIG. Fig.11 shown.

[0066] In this disclosure, please combine Figure 1 , Fig. 9 and Fig.11, there are three liquid outlet channels, including a first liquid outlet channel 601, a second liquid outlet channel 602 and a third liquid outlet channel 603. Among them, the first liquid outlet channel 601 can be connected to the top spray. The second liquid outlet channel 602 can be connected to the shower. The third liquid outlet channel 603 can be connected to the liquid outlet end 302 through a connecting mechanism 30. The liquid separation mechanism 20 includes a shell 21 and a liquid separation component 22. The shell 21 is connected to the liquid outlet mechanism 10. The liquid inlet channel 500 and a plurality of liquid outlet channels are arranged in the shell 21. The liquid separation component 22 can move relative to the shell 21. For example, the liquid separation component 22 can rotate relative to the shell 21 to selectively connect the liquid inlet channel 500 with at least one liquid outlet channel.

[0067] In addition, in some embodiments, the liquid outlet mechanism 10 can be separated from the liquid separation mechanism 20 and the connecting mechanism 30 and used separately, and the liquid inlet channel 500 and the first channel 300 are sealed together by the sealing structure 40, and the overall appearance of the liquid outlet mechanism 10 is ensured by replacing the housing 11, such as Fig.12 and Fig.13 At this time, the liquid can enter the first flow channel 300 from the liquid inlet end 301 and be discharged from the liquid outlet end 302 along the first flow channel 300, wherein the first flow channel 300 is connected with a connecting cavity 400. The liquid outlet end 302 can be connected with a water outlet faucet, a shower head, a top spray and a spray gun.

[0068] In summary, the implementation of the disclosed embodiment will have the following beneficial effects: the liquid discharge mechanism 10 of the above-mentioned scheme is applied to the liquid discharge device. In addition to having a better liquid discharge effect, it can also reduce or avoid the use of the all-copper casting structure or the stainless steel welding structure in the liquid discharge mechanism 10 by adopting the injection molded part 12 with the first flow channel 300, thereby reducing the cost of the liquid discharge mechanism 10. In addition, the first flow channel 300 is used for liquid discharge, which can avoid the contact between the liquid and the all-copper casting structure and the stainless steel welding structure, thereby improving the quality of the discharged liquid. During the installation of the injection molded part 12 on the housing 11, the housing 11 can abut against the plugging part 14, and the core pulling hole 200 is blocked by the plugging part 14, so that the injection molded part 12 does not need secondary processing or more complex injection molds to form a threaded structure or a metal insert installation structure, thereby ensuring the injection molding production efficiency. The plugging member 14 is limited by the abutment of the housing 11, which ensures the stable connection between the plugging member 14 and the injection molded part 12, thereby simplifying the structure of the plugging member 14 for improving the stable connection between the plugging member 14 and the injection molded part 12, and simplifying the structure and manufacturing process of the plugging member 14. The injection molded part 12 is supported by the housing 11 and the plugging member 14, which can ensure the structural strength of the injection molded part 12 and the stability of the connection between the injection molded part 12 and other structures. Among them, other structures may include but are not limited to the control component 13, the liquid separation mechanism 20 and the connecting mechanism 30.

[0069] In an exemplary embodiment, Figure 4As shown, a first guide surface 141 is provided at one end of the blocking member 14. During the installation of the injection molded part 12 on the housing 11, the housing 11 can slide relative to the first guide surface 141, and drive the blocking member 14 to move into the core-pulling hole 200 to seal the core-pulling hole 200. In this way, during the installation of the injection molded part 12 and the housing 11, the blocking member 14 can move to the preset position of the core-pulling hole 200 as the injection molded part 12 is installed to seal the core-pulling hole 200. Moreover, during the above process, the housing 11 can always abut against the blocking member 14, thereby ensuring a stable connection between the blocking member 14 and the injection molded part 12, preventing the blocking member 14 from moving relative to the core-pulling hole 200 toward the first guide surface 141, resulting in sealing failure, and ensuring the stability of the blocking member 14 for the core-pulling hole 200. In the disclosed embodiment, the plugging member 14 is a rotating body, and the first guide surface 141 is an arc surface symmetrical with respect to the axial axis of the plugging member 14, so that the initial positioning accuracy requirement of the plugging member 14 and the core-pulling hole 200 is relatively low, and it is sufficient to ensure that the plugging member 14 and the core-pulling hole 200 are coaxial. The core-pulling hole 200 is a stepped hole, which can form a stepped portion 121 on the injection molded part 12, and the plugging member 14 is provided with an annular protrusion 142 that is limitedly matched with the stepped portion 121.

[0070] In an exemplary embodiment, please continue to refer to Figure 4 A first seal 15 is provided between the plugging member 14 and the injection molded part 12. The first seal 15 is provided at the core-pulling hole 200 and is configured to seal the gap between the plugging member 14 and the injection molded part 12. The first seal 15 has a sealing effect on one hand, and can improve the connection stability between the plugging member 14 and the injection molded part 12 by utilizing its elastic deformation performance on the other hand. In the disclosed embodiment, the first seal 15 is annular and is sleeved on the plugging member 14. At least one of the plugging member 14 and the injection molded part 12 has an annular groove for installing the first seal 15.

[0071] In the exemplary embodiment, please combine Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figures 11 to 13, the liquid outlet mechanism 10 also includes a fastener 16, and the injection molded part 12 is fastened to the shell 11 through the fastener 16. In this way, the connection stability between the injection molded part 12 and the shell 11 can be further improved by the provision of the fastener 16, and the sealing stability of the core pulling hole 200 by the sealing member 14 can be ensured. The fastener 16 includes a first fastening portion 161 and a second fastening portion 162. The first fastening portion 161 is rotationally sealed with the injection molded part 12, so that the liquid inlet end 301 can be connected to the outside through the first fastening portion 161. The first fastening portion 161 can be threadedly connected to the shell 11. The shell 11 can be provided with a first threaded portion, and the first fastening portion 161 can be provided with a second threaded portion that matches the shell 11 to form a detachable connection. The first fastening portion 161 may also not be provided with a thread that matches the shell 11. The first fastening portion 161 can be destroyed under the action of the first threaded portion to adapt to the shape of the first threaded portion and be fastened to the shell 11. The liquid outlet mechanism 10 also includes a liquid inlet component 17, and the second fastening portion 162 can be rotatably connected to the first fastening portion 161 and threadedly connected to the liquid inlet component 17. During the process of threading the second fastening portion 162 into the liquid inlet component 17, the second fastening portion 162 can rotate relative to the first fastening portion 161 and connect the first fastening portion 161 and the liquid inlet component 17, so that the liquid can enter the liquid inlet end 301 through the liquid inlet component 17 and the first fastening portion 161 in turn.

[0072] In the disclosed embodiment, the housing 11 includes a body 111 and a connecting portion 112. The installation space 100 is located in the body 111. The connecting portion 112 is accommodated in the installation space 100. The connecting portion 112 is C-shaped, and one end is connected to the body 111. The first threaded portion is located at the inner edge of the connecting portion 112. The injection molded part 12 can be installed on the connecting portion 112 from the end of the connecting portion 112 away from the body 111, and the C-shaped opening of the connecting portion 112 can avoid the injection molded part 12. The injection molded part 12 passes through the C-shaped opening and can be supported by the connecting portion 112, ensuring the stability of the position of the injection molded part 12. There are two connecting portions 112, and they are located at both ends of the injection molded part 12, that is, at the positions where the core-pulling holes 200 at both ends of the injection molded part 12 are opened. The circumferential outer side of the connecting portion 112 is spaced apart from the body 111, which can reduce the size of the external force transmitted to the injection molded part 12 through the body 111, and ensure the connection stability between the injection molded part 12 and the connecting portion 112.

[0073] In the exemplary embodiment, please combine Figures 2 to 5 , Fig. 9 and Fig.13, the first flow channel 300 includes a liquid outlet section 303 and a plurality of liquid inlet sections 304. In the embodiment of the present disclosure, the liquid outlet section 303 can form a liquid outlet end 302 on the injection molded part 12. There are two liquid inlet sections 304, which are used to supply hot water and cold water respectively. Each liquid inlet section 304 can form a liquid inlet end 301 on the injection molded part 12. There are two liquid inlet components 17, which are connected to the two liquid inlet ends 301 in a one-to-one correspondence, and hot water and cold water are supplied to the two liquid inlet ends 301 respectively. The control component 13 is also configured to control the communication area between the liquid outlet section 303 and the plurality of liquid inlet sections 304, so that the mixing ratio of the liquids entering the liquid outlet section 303 from different liquid inlet sections 304 can be controlled. In the embodiment of the present disclosure, there are two liquid inlet sections 304, which are used to supply hot water and cold water respectively, and the control component 13 can control the mixing ratio of hot water and cold water to adjust the water temperature entering the liquid outlet section 303. The injection molded part 12 has an adjustment disk 122, and the liquid outlet section 303 can form a first through hole on the adjustment disk 122. The two liquid inlet sections 304 can form a second through hole and a third through hole on the adjustment disk 122, respectively, and the first through hole, the second through hole and the third through hole are connected to the connecting cavity 400. The part of the control component 13 located in the connecting cavity 400 can adjust the connection area between the first through hole, the second through hole and the third through hole and the connecting cavity 400. For example, the control component 13 is a temperature regulating valve core, including a fixed part, a movable part and a handle. When the handle is pushed outward relative to the housing 11, it can drive the movable part to slide relative to the fixed part, so that the first through hole, the second through hole and the third through hole are connected to the connecting cavity 400; when the handle is pushed inward relative to the housing 11, it can drive the movable part to slide relative to the fixed part, so that the first through hole, the second through hole and the third through hole are disconnected from the connecting cavity 400. When the handle is in the state of being pushed outward, the handle can be driven to rotate relative to the housing 11, so that the movable member rotates relative to the fixed member, and the area of ​​communication between the second and third via holes and the communication cavity 400 can be increased while maintaining the area of ​​communication between the first via hole and the communication cavity 400, and the area of ​​communication between the second and third via holes and the communication cavity 400 can be reduced, so as to adjust the mixing ratio of the liquid entering the liquid outlet section 303. The thermostatic valve core is a prior art, and the present disclosure does not make any improvements to the thermostatic valve core.

[0074] In the exemplary embodiment, please combine Figures 5 to 7 and Fig.10 The connecting mechanism 30 includes a hose 31, and the hose 31 is connected between the liquid outlet end 302 and one of the liquid outlet channels. Since the liquid outlet end 302 and one of the liquid outlet channels do not need to be connected by a metal screw, the position accuracy requirements of the liquid outlet mechanism 10 and the liquid separation mechanism 20 and the assembly accuracy requirements with the hose 31 can be reduced, thereby reducing costs and improving assembly efficiency. In the disclosed embodiment, the hose 31 is made of polyethylene (PE).

[0075] In the exemplary embodiment, please combine Figure 5 , Figure 6 and Figures 8 to 10 , the connecting mechanism 30 also includes a joint assembly 32. The joint assembly 32 includes a connecting piece 321 and an elastic piece 322. At least one of the liquid outlet mechanism 10 and the liquid separation mechanism 20 is provided with the connecting piece 321. The hose 31 is passed through the elastic piece 322 and is clamped with the connecting piece 321 through the elastic piece 322. In this way, the hose 31 and the connecting piece 321 can be quickly assembled through the elastic piece 322, thereby improving the assembly efficiency. In the disclosed embodiment, the liquid outlet mechanism 10 and the liquid separation mechanism 20 both have a connecting piece 321, so that both ends of the hose 31 can be quickly assembled with the liquid outlet mechanism 10 and the liquid separation mechanism 20 respectively through the joint assembly 32, and the connecting piece 321 can be connected with the liquid outlet mechanism 10 and the liquid separation mechanism 20 by clamping, bonding or welding.

[0076] In the exemplary embodiment, please combine Figure 6 and Figures 8 to 10 The circumferential outer wall of the connecting member 321 is provided with a first protrusion 323, and the first protrusion 323 can be embedded in the liquid outlet mechanism 10 and the liquid dispensing mechanism 20 connected to the connecting member 321 or the liquid outlet mechanism 10 and the liquid dispensing mechanism 20 connected to the connecting member 321 are interference fit. In this way, the connection stability of the connecting member 321 can be increased by the provision of the first protrusion 323. In the embodiment of the present disclosure, the first protrusion 323 is a claw made of a steel sheet material, which can be embedded in the liquid outlet mechanism 10 and the liquid dispensing mechanism 20 connected to the connecting member 321, further improving the connection stability of the connecting member 321.

[0077] In the exemplary embodiment, please combine Fig. 9 and Fig.10 The connecting member 321 is provided with a second guide surface 3211, and the elastic member 322 can slide toward the inside of the connecting member 321 through the second guide surface 3211. In this way, the provision of the second guide surface 3211 can facilitate the elastic member 322 to be quickly inserted into the connecting member 321 and to be snap-fitted with the connecting member 321. In addition, the second guide surface 3211 can also play a certain positioning role, facilitating the rapid positioning of the elastic member 322 and the connecting member 321, and to complete the snap-fitting. In the disclosed embodiment, the second guide surface 3211 is annular, and can be, but not limited to, an arcuate surface, a conical surface, or a pyramidal surface.

[0078] In the exemplary embodiment, please combine Figure 6 and Figures 8 to 10The elastic member 322 includes a ring portion 3221 and a plurality of elastic arms 3222 disposed on the ring portion 3221. The plurality of elastic arms 3222 are disposed at intervals around the axial direction of the ring portion 3221 and enclose a plug-in space. The hose 31 can be sequentially passed through the ring portion 3221 and the plug-in space and clamped by the elastic arms 3222. The elastic arms 3222 can change the size of the plug-in space according to the size of the hose 31 so as to clamp the hose 31. In order to improve the clamping force on the hose 31, the elastic arm 3222 can be bent toward one side of the plug-in space in whole or in part, and can produce greater elastic deformation after contacting the hose 31, thereby improving the clamping force on the hose 31. In the embodiment of the present disclosure, the number of elastic arms 3222 is 6, and it can be understood that in other embodiments, the number of elastic arms 3222 can also be other values. The setting of the ring portion 3221 can connect the plurality of elastic arms 3222 into one, thereby ensuring the stability of the overall structure of the elastic member 322 and the stability of the elastic deformation of the elastic arms 3222.

[0079] In an exemplary embodiment, please continue to refer to Figure 6 and Figures 8 to 10 At least one of the side of the connecting member 321 facing the hose 31 and the side of the elastic arm 3222 away from the hose 31 is provided with a third guide surface 3223 , and the side of the connecting member 321 facing the hose 31 is provided with a receiving groove 700 .

[0080] The elastic arm 3222 slides with the connector 321 through the third guide surface 3223, and in the process of being inserted into the receiving groove 700 along the first direction, the multiple elastic arms 3222 can gradually gather toward the plug-in space to compress and deform the hose 31, and when the multiple elastic arms 3222 are accommodated in the receiving groove 700, they are spread out toward the side away from the plug-in space to reset the hose 31. In this way, by setting the third guide surface 3223, when the elastic arm 3222 slides toward the receiving groove 700 relative to the connector 321, the hose 31 can be further clamped and held tightly, ensuring that the hose 31 and the elastic member 322 can slide toward the receiving groove 700 synchronously. The setting of the receiving groove 700 can ensure that the elastic arm 3222 clamps the hose 31 while preventing the hose 31 from being excessively deformed and affecting the fluidity of the liquid in the hose 31. The first direction is parallel to Fig.10 The direction indicated by the arrow X. In the embodiment of the present disclosure, the third guide surface 3223 may be, but is not limited to, an arcuate surface or an inclined surface.

[0081] In an exemplary embodiment, Fig.10As shown, the connector 321 is provided with a first limiting portion 3212. The first limiting portion 3212 is located on the insertion side of the accommodating groove 700 close to the elastic arm 3222 and away from the insertion side of the elastic arm 3222. The elastic arm 3222 is provided with a second limiting portion 3224, and the second limiting portion 3224 faces the insertion side of the elastic arm 3222. The first limiting portion 3212 and the second limiting portion 3224 can be limitedly matched to prevent the elastic arm 3222 from escaping from the accommodating groove 700 from the insertion side of the elastic arm 3222. In this way, the first limiting portion 3212 and the second limiting portion 3224 can prevent the connector 321 and the elastic member 322 from being separated from the accommodating groove 700 when the hose 31 is subjected to an external force in the opposite direction to the insertion direction, thereby ensuring the connection stability of the hose 31 and the joint assembly 32. The first limiting portion 3212 and the second limiting portion 3224 are both annular platform structures.

[0082] In the exemplary embodiment, please combine Fig. 9 and Fig.10 , the accommodating groove 700 can form a groove wall 3213 on the connecting member 321, and the elastic arm 3222 can abut against the groove wall 3213, so that the elastic arm 3222 can be supported by the groove wall 3213, thereby ensuring the clamping force on the hose 31. The groove wall 3213 gradually narrows toward the side of the first limiting portion 3212, so that the elastic deformation of the elastic arm 3222 gradually increases as it moves toward the side of the first limiting portion 3212, thereby gradually increasing the clamping force on the hose 31, and reducing the risk of the hose 31 sliding relative to the elastic member 322 and separating from the joint assembly 32 after the first limiting portion 3212 and the second limiting portion 3224 are limited and matched. In the embodiment of the present disclosure, the groove wall 3213 is in the shape of an annular arc surface, so that the elastic arm 3222 can rotate freely relative to the axial direction of the groove wall 3213, so as to avoid twisting of the hose 31 and the need for reassembly when assembling the joint assembly 32. It can be understood that in other embodiments, the groove wall 3213 can also be in the shape of an annular conical surface.

[0083] In the exemplary embodiment, please combine Figure 6 and Figures 7 to 10 , a second protrusion 324 is provided on the side of the elastic arm 3222 facing the plug-in space. Since the second protrusion 324 exists between the elastic arm 3222 and the outer wall of the hose 31, the elastic deformation of the elastic arm 3222 and the outer wall of the hose 31 is increased, thereby improving the clamping force of the elastic arm 3222 on the hose 31, increasing the clamping stability of the elastic arm 3222 on the hose 31, and reducing the risk of the hose 31 moving relative to the elastic arm 3222. In the disclosed embodiment, the second protrusion 324 is a claw made of steel sheet material, which can ensure the structural stability after contacting the hose 31. The second protrusion 324 can be embedded in the hose 31 or have an interference fit with the hose 31.

[0084] In the exemplary embodiment, please combine Fig. 9 and Fig.10 , the inner edge of the ring portion 3221 is provided with a fourth guide surface 3225, and the hose 31 can pass through the ring portion 3221 and the plug-in space in sequence through the fourth guide surface 3225. In this way, the fourth guide surface 3225 can be provided to facilitate the hose 31 to be quickly inserted into the elastic member 322 and to complete the plug-in connection with the elastic member 322. In addition, the fourth guide surface 3225 can also play a certain positioning role, facilitating the rapid positioning of the hose 31 and the elastic member 322 to complete the plug-in connection. In the embodiment of the present disclosure, the fourth guide surface 3225 is annular, and can be, but not limited to, an arc-shaped surface, a conical surface, or a pyramidal surface.

[0085] In the exemplary embodiment, please combine Figure 6 and Figures 8 to 10 A second sealing member 50 is provided between the hose 31 and the liquid outlet mechanism 10 and between the hose 31 and the liquid separation mechanism 20, respectively, to ensure the sealing between the hose 31 and the liquid outlet mechanism 10 and between the hose 31 and the liquid separation mechanism 20. In the disclosed embodiment, the second sealing member 50 is annular and is sleeved on the hose 31.
