[0048] Reference below Figure 1-Figure 15 The liquid dispenser 100 according to the embodiment of the utility model is described. When the liquid dispenser 100 is disassembled, the pre-tightening member 22 applies elastic force to the shielding structure 23, and the shielding structure 23 closes the liquid outlet 21, thereby reducing the amount of liquid leakage and the cleaning work. The structure is simple and easy to use.

[0049] like Figure 1-Figure 15 As shown, a liquid dispenser 100 according to an embodiment of the present invention includes: a liquid dispenser body 1 and a liquid dispenser cover 2.

[0050] A liquid storage cavity 11 is formed in the liquid discharger body 1, and the liquid storage cavity 11 is used to store liquid. The liquid discharger body 1 is provided with a delivery port 12 connected with the liquid storage cavity 11, that is, the liquid is delivered through the delivery port 12. In this embodiment, the liquid discharger 100 can be used as an external laundry detergent discharger, and a liquid storage cavity 11 is formed in the liquid discharger body 1, which can be used to store various laundry detergents. A delivery port 12 is provided at the end of the liquid discharger body 1, and the delivery port 12 is connected with the liquid storage cavity 11. The delivery port 12 of the liquid discharger body 1 can be connected to a washing machine, and after the washing machine is started, the laundry detergent can be delivered from the delivery port 12. Of course, the liquid discharger 100 in this embodiment can also be used to deliver detergents or liquids for other purposes, and has a wide range of applications.

[0051] The liquid outlet cover 2 is installed at the loading port 12, and is provided with a liquid outlet 21 connected with the loading port 12. The liquid outlet cover 2 is provided with a pre-tightening member 22 and a movable shielding structure 23. The pre-tightening member 22 acts on the shielding structure 23 to drive the shielding structure 23 to close the liquid outlet 21. When the external force is greater than the driving force acting on the shielding structure 23, the shielding structure 23 opens the liquid outlet 21 to connect the liquid storage chamber 11 with the liquid outlet 21.

[0052] That is, when the pre-tightening member 22 applies a driving force to the shielding structure 23, the liquid outlet 21 can be closed, and the thrust moving toward the delivery port 12 can open the liquid outlet 21. When the external force applied to the shielding structure 23 is greater than the driving force applied to the shielding structure 23 by the pre-tightening member 22, the liquid outlet 21 can be opened. In general, the shielding structure 23 closes the liquid outlet 21 to prevent liquid leakage, and when the shielding structure 23 is subjected to force, the liquid outlet 21 is opened to deliver liquid.

[0053] Specifically, the liquid outlet cover 2 is provided with a liquid outlet 21, and the liquid outlet 21 is communicated with the delivery port 12, and the liquid outlet cover 2 is detachably connected to the liquid outlet body 2, and the pre-tightening member 22 and the shielding structure 23 are installed in the liquid outlet cover 2 and installed close to the liquid outlet 21, and the shielding structure 23 can move relative to the liquid outlet 21 to open or close the liquid outlet 21, wherein, when liquid needs to be delivered, an external force is applied to the shielding structure 23, and when the external force is greater than the driving force of the pre-tightening member 22 on the shielding structure 23, the shielding structure 23 is moved. The shielding structure 23 moves toward the inside of the delivery port 12, so that the shielding structure 23 gradually moves away from the liquid outlet 21, and the liquid outlet 21 can be opened, and the liquid in the liquid storage chamber 11 flows out from the delivery port 12 and the liquid outlet 21 to achieve liquid discharge. When the delivery is completed, the external force is gradually removed. At this time, the external force is smaller than the driving force of the pre-tightening member 22 on the shielding structure 23. The pre-tightening member 22 drives the shielding structure 23 to move in the opposite direction, so that the shielding structure 23 closes the liquid outlet 21 and stops the liquid discharge. The movement mode of the shielding structure 23 is simple, reliable and low in cost.

[0054] Therefore, the liquid dispenser cover 2 and the liquid dispenser body 2 are installed at the injection port 12, and after the pre-tightening member 22 cooperates with the shielding structure 23, the shielding structure 23 is movable relative to the liquid outlet 21, so that liquid can be discharged and closed. The closing method is simple, and the shielding structure 23 has good reset performance, which can reduce the amount of liquid leakage, thereby reducing the waste of laundry detergent, and can reduce cleaning work, thereby improving the use effect of the liquid dispenser 100.

[0055] According to the liquid dispenser 100 of the utility model embodiment, a pre-tightening member 22 and a shielding structure 23 are arranged on the liquid dispenser cover body 2, so that the shielding structure 23 is forced to open the liquid outlet 21 to achieve liquid discharge, and the pre-tightening member 22 can drive the shielding structure 23 to close the liquid outlet 21 to achieve the resetting of the shielding structure 23, thereby reducing the amount of liquid spillage when the liquid dispenser 100 is pulled out, thereby reducing the cleaning workload, facilitating operations such as adding liquid and machine maintenance, and being more reliable and convenient to use.

[0056] In some embodiments, the shielding structure 23 is rotatably connected to the liquid outlet cover 2, and the shielding structure 23 is configured to open the liquid outlet 21 when it rotates along a first direction, and the pre-tightening member 22 is used to apply a driving force to the shielding structure 23 to rotate along a second direction, and the first direction is opposite to the second direction. That is, when the shielding structure 23 rotates along the first direction, the liquid outlet 21 is opened, and when the liquid outlet 21 is closed, the shielding structure 23 is driven by the pre-tightening member 22 to rotate along the second direction to close the liquid outlet 21.

[0057] Specifically, the shielding structure 23 is installed in the liquid outlet cover 2 and can be rotated relative to the liquid outlet cover 2, wherein the liquid outlet 21 can be constructed as a circular hole, and the shape of the shielding structure 23 can be constructed as a circular plate. The shielding structure 23 is matched with the shape of the liquid outlet 21, so that the shielding structure 23 has good sealing performance when closing the liquid outlet 21.

[0058] Among them, the first direction can be counterclockwise, and the second direction can be clockwise. The shielding structure 23 can rotate along the first direction or the second direction relative to the liquid outlet 21 to realize the opening or closing of the liquid outlet 21. When liquid needs to be added, the shielding structure 23 can be pushed to rotate in the counterclockwise direction to open the liquid outlet 21, and the liquid flows out from the addition port 12 and the liquid outlet 21 to realize liquid discharge. When the addition is completed, the pre-tightening member 22 drives the shielding structure 23 to move in the clockwise direction to close the liquid outlet 21 and stop the liquid discharge. At this time, the liquid dispenser 100 can be pulled out for maintenance or liquid replenishment, etc.

[0059] Therefore, the pre-tightening member 22 can actively drive the shielding structure 23 to move and close the liquid outlet 21, and the closing of the liquid outlet 21 has good sealing performance, which can reduce liquid leakage and reduce liquid waste. The movement method of the shielding structure 23 is simple and the use effect is good.

[0060] In some embodiments, the shielding structure 23 is rotatably connected to the liquid outlet cover 2 via a connecting shaft 24, and the preload member 22 is constructed as a torsion spring, which is sleeved on the connecting shaft 24, with one end of the torsion spring pressing against the shielding structure 23 and the other end pressing against the liquid outlet cover 2. In this way, when the liquid outlet 21 is closed, the torsion spring pushes the shielding structure 23 to rotate to close the liquid outlet 21.

[0061] Specifically, the connecting shaft 24 is used to install the preload member 22, and the shielding structure 23 is rotatably connected to the liquid outlet cover 2 through the connecting shaft 24. In actual design, Figure 5 , Figure 6 As shown, the connecting shaft 24 can be a separate part, and the liquid discharger cover body 2 is provided with a mounting hole, and the mounting holes are distributed near the liquid outlet 21. The connecting shaft 24 is connected to the liquid discharger cover body 2 through the mounting hole, and the shielding structure 23 is provided with a connecting hole, and the shielding structure 23 is rotatably connected to the connecting shaft 24 through the connecting hole, wherein the preload member 22 is constructed as a torsion spring, and the torsion spring is sleeved outside the connecting shaft 24, and one end of the torsion spring is pressed and matched with the shielding structure 23, and the other end of the torsion spring is pressed and matched with the liquid discharger cover body 2, so as to realize the rotational connection of the shielding structure 23, and its structure is simple and the cost is low.

[0062] When the shielding structure 23 is subjected to a force moving toward the liquid storage chamber 11, the shielding structure 23 rotates counterclockwise around the connecting shaft 24 to open the liquid outlet 21. After the liquid is discharged, the torsion spring presses the shielding structure 23, and the shielding structure 23 rotates clockwise around the connecting shaft 24 to close the liquid outlet 21, thereby stopping the liquid discharge. Closing the liquid outlet 21 reduces the amount of liquid leakage, ensuring the cleanliness of the connection between the liquid discharge device 100 and other structures, thereby reducing the cleaning workload.

[0063] Among them, the connection method of the shielding structure 23 is not limited to the above-mentioned method. For example, the connecting shaft 24 can be constructed as an integral structure with the shielding structure 23, and the connecting shaft 24 on the shielding structure 23 is connected to the mounting hole. Also, the connecting shaft 24 can be constructed as an integral structure with the liquid discharger cover 2, and a connecting hole is provided on the shielding structure 23, and the shielding structure is connected to the connecting shaft 24 on the liquid discharger cover 2 through the connecting hole. Both of these methods can realize the rotatable connection between the shielding structure 23 and the liquid discharger cover 2. Therefore, the connection method of the shielding structure 23 is diversified and highly selective.

[0064] In some embodiments, the shielding structure 23 includes a main board portion 231 and a sub-board portion 232, and an intermediate section 233 is connected between the main board portion 231 and the sub-board portion 232. The main board portion 231 is movably connected to the liquid outlet cover 2, and the sub-board portion 232 is suitable for extending into the liquid outlet 21. The intermediate section 233 is provided with a first sealing member 27 for pressing against the end face of the liquid outlet 21.

[0065] Specifically, Figure 3 As shown, the shielding structure 23 includes a main board portion 231 and a sub-board portion 232, and the main board portion 231 and the sub-board portion 232 are connected by an intermediate section 233. In a specific design, the main board portion 231, the intermediate section 233 and the sub-board portion 232 can be constructed as a circular structure, the main board portion 231 is connected to the inner cover body 25 of the liquid discharger cover body 2, and can move relative to the inner cover body 25, the intermediate section 233 can be constructed as a mounting groove for mounting the first sealing member 27, and the mounting groove extends along the circumferential direction, wherein the first sealing member 27 can be constructed as an annular shape, and the annular first sealing member 27 can be mounted on the inner cover body 25 of the liquid discharger cover body 2. The sealing member 27 is sleeved outside the mounting groove, and the outer diameter of the sub-plate portion 232 is smaller than the outer diameter of the liquid outlet 21, which facilitates the sub-plate portion 232 to extend into the liquid outlet 21, wherein the first sealing member 27 can be made of rubber or other materials, and the first sealing member 27 can be set as a sealing ring. When the pre-tightening member 22 drives the shielding structure 23 to close the liquid outlet 21, the sub-plate portion 232 extends into the liquid outlet 21, and the shielding structure 23 presses the sealing ring against the end face of the liquid outlet 21, and the circumferential circle of the liquid outlet 21 can be sealed, and the sealing effect is good, which effectively reduces the outflow of liquid.

[0066] In some embodiments, the liquid outlet cover 2 also includes a mounting seat 28, which is located in the injection port 12 and connected to the liquid outlet 21, the shielding structure 23 is located in the mounting seat 28, and the preload member 22 is constructed as a spring, which elastically presses between the shielding structure 23 and the mounting seat 28 to drive the shielding structure 23 to close the liquid outlet 21. That is to say, the shielding structure 23 and the mounting seat 28 are elastically pressed by the spring, so that the shielding structure 23 presses against the liquid outlet 21, thereby realizing that the shielding structure 23 closes the liquid outlet 21.

[0067] Specifically, the mounting seat 28 is used to connect the liquid storage cavity 11 with the liquid outlet 21 of the liquid outlet cover 2. Figure 8-Figure 9 and Figure 11-Figure 12 As shown, the mounting seat 28 is located in the injection port 12 and is connected to the structure at the liquid outlet 21. The mounting seat 28 can be fixed to the liquid outlet 21 by other means such as plugging and snapping. The shielding structure 23 is provided at the liquid outlet 21 and is located in the mounting seat 28. The pre-tightening member 22 is located between the mounting seat 28 and the shielding structure 23. The pre-tightening member 22 can be constructed as a spring. Both ends of the spring are elastically pressed between the shielding structure 23 and the mounting seat 28. The spring can press the shielding structure 23 to press the end of the liquid outlet 21. At this time, when the shielding structure 23 closes the liquid outlet 21, the spring is in an extended state to press the shielding structure 23 toward the liquid outlet 21 for pre-tightening. This can ensure that the shielding structure 23 is reliably attached to the liquid outlet 21, reduce waste caused by liquid outflow, and has a simple structure and low cost.

[0068] The mounting seat 28 is provided with a connecting port 281 for connecting the liquid outlet 21 with the liquid storage chamber 11, that is, the liquid storage chamber 11 can be connected with the liquid outlet 21 through the connecting port 281, and when the shielding structure 23 opens the liquid outlet 21, the liquid in the liquid storage chamber 11 flows out to the liquid outlet 21 through the connecting port 281 to achieve liquid discharge.

[0069] Specifically, Figure 8 and Fig.10 As shown, the mounting seat 28 is constructed as a circular structure, and the mounting seat 28 is provided with a connecting port 281 at a position close to the liquid outlet 21, wherein there may be multiple connecting ports 281, and the multiple connecting ports 281 are distributed and spaced apart along the circumference of the mounting seat 28. In the present embodiment, there are four connecting ports 281, and the mounting seat 28 is connected to the liquid outlet 21 through the four connecting ports 281 in the circumferential direction. When the liquid is discharged, the liquid flows from the four connecting ports 281 to the liquid outlet 21, and the liquid can be fully discharged. The number of the connecting ports 281 can also be set to two, three, etc., which is not limited to what is described in the present embodiment, and can be flexibly arranged according to actual needs.

[0070] Furthermore, the spring and the torsion spring are both elastic parts, and the elastic parts are used to apply an elastic force to the shielding structure 23 to close the liquid outlet 21. That is, by applying an elastic force to the shielding structure 23 by the elastic part, the shielding structure 23 can be pushed to move toward the liquid outlet 21 to close the liquid outlet 21.

[0071] Specifically, the elastic member has an elastic force. In both states, the elastic force and the thrust of the elastic member act on the shielding structure 23, and the directions of the two are opposite. When the liquid discharger body 1 is pulled out after the liquid discharge is completed, when the thrust received by the shielding structure 23 is smaller than the elastic force, the elastic member pushes the shielding structure 23 to rotate or approach the liquid outlet to close the liquid outlet 21, thereby stopping the liquid discharge.

[0072] Therefore, by setting an elastic member connected to the shielding structure 23, the shielding structure 23 can be switched from opening the liquid outlet 21 to closing the liquid outlet 21, thereby resetting the shielding structure 23 and reducing the outflow of liquid from the liquid outlet 21.

[0078] Specifically, Figure 8 , Fig. 9 As shown, the shielding structure 23 is partially sleeved with a first sealing member 27 near the liquid outlet 21.

[0084] Specifically, the inner cover body 25 includes two parts, namely an inner part 251 and an outer part 252. The inner part 251 is connected to the outer part 252. In actual design, Figure 1 and Figure 2 As shown, both the inner portion 251 and the outer portion 252 can be constructed as a cylinder, the inner portion 251 and the outer portion 252 are coaxially distributed, and the two are radially spaced apart, the outer portion 252 extends in the same direction as the inner portion 251, and the axial extension length of the outer portion 252 is smaller than the axial extension length of the inner portion 251, and the outer portion 252 is connected to the inner portion 251 at the end of the delivery port 12. In the specific design, the outer portion 252 and the inner portion 251 can be constructed as an integral structure to reduce the setting of the connection structure between the two.

[0085] Among them, one of the liquid dispenser body 1 and the inner cover body 25 of the liquid dispenser cover body 2 is provided with a snap-on protrusion 131, and the other is provided with a snap-on groove 253, and the snap-on groove 253 is snap-on-fit with the snap-on protrusion 131, that is, the liquid dispenser body 1 can be provided with a snap-on protrusion 131, and the inner cover body 25 is provided with a snap-on groove 253, or the liquid dispenser body 1 can be provided with a snap-on groove 253, and the inner cover body 25 is provided with a snap-on protrusion 131, and the above two configurations can realize the snap-on connection between the inner cover body 25 and the liquid dispenser body 1. Specifically, as Figure 3 As shown, the liquid dispenser body 1 is provided with a snap-fitting protrusion 131 on the outer peripheral wall of the step structure 13, and correspondingly, the inner peripheral wall of the outer side portion 252 of the inner cover body 25 is provided with a snap-fitting groove 253, which can snap-fit ​​and connect the outer side portion 252 with the snap-fitting protrusion 131 of the outer peripheral wall of the delivery port 12, and a limiting protrusion 254 is provided at the connection between the outer side portion 252 and the inner side portion 251, which protrudes axially and extends circumferentially along the inner cover body 25, and is used to press against the inner peripheral wall of the delivery port 12 for limiting.

[0086] During installation, the inner side portion 251 is extended into the delivery port 12, the engaging groove 253 is engaged with the engaging protrusion 131 and the limiting protrusion 254 is pressed against the inner circumferential wall of the delivery port 12, so as to realize axial and circumferential limiting of the inner cover body 25, and the end of the delivery port 12 is in contact with the inner bottom wall of the inner cover body 25, so that the installation of the inner cover body 25 and the liquid dispenser body 1 can be realized. The installation is simple and reliable, and the liquid can be prevented from flowing out of the delivery port 12.

[0087] The liquid outlet 21 is arranged on the inner part 251, and the shielding structure 23 is movably connected to the outside of the inner part 251. Specifically, the liquid outlet 21 is arranged at the center of the inner part 251, and the shielding structure 23 is connected to the outer side of the inner part 251 close to the liquid outlet 21, and is movable relative to the inner part 251. The liquid outlet 21 can be opened or closed during the movement of the shielding structure 23. After the inner cover body 25 and the liquid outlet body 1 are installed, the liquid outlet body 1 is connected to the liquid outlet device, and a thrust is applied to the shielding structure 23 to push the shielding structure 23 to move to open the liquid outlet 21 to realize liquid discharge. Conversely, in the process of removing the liquid outlet 100, the shielding structure 23 is pushed by the elastic thrust of the preload member 22 to move in the opposite direction to close the liquid outlet 21 and stop the liquid discharge. Therefore, the liquid outlet 21 and the shielding structure 23 are both arranged on the inner part 251, the structure is compact and the movement is easier to realize.

[0088] In some embodiments, the outer cover body 26 is provided with a protruding inner top opening portion 261, which is suitable for extending into the liquid outlet 21 and acting on the shielding structure 23 after the outer cover body 26 is connected to the liquid outlet body 1, so that the shielding structure 23 opens at least part of the liquid outlet 21, so that the internal and external gases of the liquid outlet body 1 are connected after the outer cover body 26 is opened, so as to reduce the internal and external pressure difference.

[0089] Specifically, Fig.14 and Fig.15 As shown, an inner side of the outer cover body 26 is provided with an inner top opening portion 261, wherein the inner top opening portion 261 is provided at the center position of the outer cover body 26 and extends toward one side of the liquid storage chamber 11, and the extension length is greater than the distance from the liquid outlet 21 to the inner surface of the outer cover body 26. In actual design, the inner top opening portion 261 and the outer cover body 26 can be an integral structure, wherein the shape of the inner top opening portion 261 can be cylindrical, square, etc. After the outer cover body 26 is connected to the liquid outlet body 1, the inner top opening portion 261 extends to the liquid outlet 21 and applies a thrust to the shielding structure 23, thereby at least partially opening the liquid outlet 21 to communicate with the liquid storage chamber 11 and the liquid outlet 21.

[0090] Among them, when the temperature is high, the air pressure in the liquid storage chamber 11 will increase. Therefore, by setting the liquid storage chamber 11 to be connected with the liquid outlet 21, the atmosphere in the liquid storage chamber 11 is connected with the atmosphere of the liquid outlet 21, and when the outer cover 26 is opened, the atmosphere in the liquid storage chamber 11 can be instantly connected with the external atmosphere to balance the internal and external air pressures of the liquid outlet body 1.

[0091] In some embodiments, the liquid outlet 100 also includes an air flow tube 3, which is passed through the liquid outlet body 1 or the liquid outlet cover 2, one end of the air flow tube 3 is connected to the liquid storage chamber 11 and the other end is connected to the outside of the liquid storage chamber 11. In this way, the airway connection between the inside and outside of the liquid storage chamber 11 is achieved through the air flow tube 3, and the internal and external air pressures of the liquid outlet 100 can be balanced.

[0092] Specifically, the liquid dispenser 100 is further provided with an air flow capillary 3, which can be connected to the liquid dispenser body 1, or the air flow capillary 3 can be connected to the liquid dispenser cover 2. Both of these arrangements can connect the internal space of the liquid dispenser 100 with the external space, and can be selectively arranged according to actual design requirements, such as Figure 7 , Fig.11 and Fig.12 As shown, the airflow capillary 3 is connected to the liquid outlet cover 2, and one end of the airflow capillary 3 is connected to the liquid storage cavity 11, and the other end is connected to the outside of the liquid storage cavity 11. In this way, the liquid outlet 100 realizes the connection between the internal and external airways at the airflow capillary 3. By providing the airflow capillary 3, external air can be introduced into the liquid outlet 100 through the airflow capillary 3 to balance the air pressure in the liquid outlet 100 with the external air pressure, so that the liquid can flow out smoothly when the liquid is discharged from the liquid outlet 100, avoiding the imbalance of the internal and external air pressures and causing difficulty in discharging the liquid.

[0093] Among them, the aperture of the airflow tube 3 is set to be relatively small, and the aperture range is between 0.4mm and 0.6mm, and the value can be 0.5mm, etc. This setting can introduce external air into the liquid outlet 100, and the small aperture reduces the leakage of liquid in the liquid storage chamber 11 at the connection between the airflow tube 3 and the liquid outlet cover 2. The structure is simple and reliable.

[0094] Furthermore, as the temperature rises, the air pressure in the liquid storage chamber 11 will increase, causing liquid to emerge from the mouth of the airflow tube 3 when the outer cover 26 is opened. The above-mentioned inner top opening portion 261 is provided to open the shielding structure 23, so that the atmosphere in the liquid storage chamber 11 and the external atmosphere can be connected when the outer cover 26 is opened, thereby avoiding liquid leakage at the mouth of the airflow tube 3 and reducing liquid waste.

[0095] In some embodiments, the gas flow tube 3 is extended vertically, and the upper end of the gas flow tube 3 is connected to the liquid storage cavity 11 and the lower end is connected to the outside of the liquid storage cavity 11.

[0096] Specifically, the air flow tube 3 can extend in different directions, such as the air flow tube 3 can be extended vertically or horizontally. In this embodiment, Figure 7 , Fig.11 and Fig.12 As shown, the gas flow tube 3 is extended vertically, that is, the gas flow tube 3 vertically penetrates the liquid outlet cover 2. In actual design, the gas flow tube 3 can be connected to the liquid outlet cover 2 by snapping or plugging. Fig.13 As shown, the liquid discharger cover 2 is provided with a plug-in groove 2512 on the inner side of the liquid storage chamber 11, and the plug-in groove 2512 extends vertically, and a flow hole 2513 is provided at the plug-in groove 2512, and the flow hole 2513 runs through the liquid discharger cover 2. During installation, the airflow tube 3 is plugged into the plug-in groove 2512, and the upper end of the airflow tube 3 is connected to the liquid storage chamber 11, and the lower end of the airflow tube 3 can be directly extended to the outside of the liquid storage chamber 11, or the lower end of the airflow tube 3 is connected to the outside of the liquid storage chamber 11 through the flow hole 2513, so that the arrangement of the airflow tube 3 can be realized, and the airflow tube 3 and the plug-in groove 2512 are tightly matched to prevent liquid leakage, and the plug-in connection method is simple and reliable.

[0097] The utility model also provides a liquid discharge device.

[0098] According to the embodiment of the utility model, the liquid discharge device includes a device body and a liquid discharge device 100 of any one of the above-mentioned embodiments, the device body is provided with a placement port, and a push-opening member 200 is provided at the placement port, and the push-opening member 200 is used to act on the shielding structure 23 to open the liquid discharge port 21 when the liquid discharge device 100 is inverted at the placement port.

[0099] Specifically, a placement port is provided on the device body, and the placement port is used to place the liquid dispenser 100. Figure 2 , Figure 3 and Figure 6 As shown, a push-up member 200 is provided at the center of the placement port, and the push-up member 200 extends toward the shielding structure 23, and the push-up member 200 is used to apply a thrust to the shielding structure 23. Among them, the outside of the delivery port 12 of the liquid discharger 100 can be a cylindrical structure, and the placement port can be matched with the external structure of the delivery port 12. The size of the placement port is larger than the outer diameter of the delivery port 12. The liquid discharger 100 is inverted at the placement port. At the same time, the push-up member 200 applies an upward thrust to the shielding structure 23, pushing the shielding structure 23 to move in a direction away from the liquid outlet 21, opening the liquid outlet 21, and the liquid outlet 21 is connected with the placement port to achieve liquid discharge.

[0100] Therefore, a pre-tightening member 22 and a shielding structure 23 are provided on the liquid outlet cover 2, so that the shielding structure 23 is pushed by the top opening member 200 to open the liquid outlet 21 to realize liquid discharge, and the pre-tightening member 22 can drive the shielding structure 23 to close the liquid outlet 21 to realize the reset of the shielding structure 23, thereby reducing the amount of liquid spillage when the liquid outlet 100 is pulled out, thereby reducing the workload of cleaning, facilitating operations such as adding liquid and machine maintenance, and making it more reliable and convenient to use. Among them, when the liquid outlet 100 of this embodiment is in an inverted or flat state, the injection port 12 is connected to the device body, and the shielding structure 23 is pushed open by the top opening member 200 to realize liquid discharge, and it has many usage scenarios and strong versatility.

[0101] In some embodiments, a second sealing member 203 is provided on the outer peripheral wall of the opening member 200. When the opening member 200 opens the shielding structure 23, the second sealing member 203 is sealed with the inner peripheral wall of the liquid outlet 21. Thus, when the liquid outlet 100 discharges liquid, the second sealing member 203 is circumferentially pressed against the inner peripheral wall of the liquid outlet 21, thereby achieving a sealing effect on the liquid outlet 21 to prevent liquid from flowing out.

[0102] Specifically, Figure 7 and Fig.12 As shown, the push-up member 200 is provided with a second sealing member 203 near the liquid outlet 21. For example, a mounting groove is provided on the outer peripheral wall of the push-up member 200, the mounting groove extends in the circumferential direction, and the second sealing member 203 can be constructed in a ring shape. The ring-shaped second sealing member 203 is sleeved outside the mounting groove, and the outer diameter of the push-up member 200 is smaller than the outer diameter of the liquid outlet 21, which is beneficial for the push-up member 200 to extend into the liquid outlet 21 to push open the shielding structure, wherein the second sealing member 203 can be made of rubber or other materials, and the second sealing member 203 can be set as a sealing ring. When the push-up member 200 pushes open the liquid outlet 21, the second sealing member 203 presses against the inner peripheral wall of the liquid outlet 21, and can seal the circumferential circle of the liquid outlet 21.

[0103] Therefore, by providing the second sealing member 27 to elastically press against the inner wall of the liquid outlet 21, the liquid outlet 100 has good sealing performance when discharging liquid, which can reduce waste caused by liquid outflow, and has a simple structure and low cost.

[0104] It should be noted that a second sealing member 203 is provided at the liquid outlet 21. Figure 7 and Fig.12 When the liquid outlet 21 is in a sealed state, the top opening 200 is directly connected to the liquid outlet 100, a negative pressure is formed in the liquid outlet body 1, and the airflow capillary 3 balances the pressure in the liquid outlet body 1. When the second sealing member 203 is not provided at the liquid outlet 21, that is, the liquid outlet 21 is in a non-sealed state, the airflow capillary 3 will increase the liquid discharge speed (especially for viscous liquids such as laundry detergent and softener), and in a normal state, the liquid seal position will block the mouth of the airflow capillary 3 and will not be connected to the outside atmosphere, causing all the liquid in the liquid outlet body 1 to flow out.

[0105] In some embodiments, a guide channel 201 is formed in the top opening member 200, and the top opening member 200 is provided with a guide port 202 connected to the guide channel 201, and the guide port 202 is constructed to have an inclined cross-section. In this way, the guide port 202 of the top opening member 200 pushes the shielding structure 23 to open the liquid outlet 21, and the liquid outlet 21 is connected to the guide channel 201 of the top opening member 200, so that the liquid is introduced into the device body through the guide port 202.

[0106] The shielding structure 23 is rotatably connected to the liquid dispenser cover 2 via a connecting shaft 24 , and the inclined surface is tilted and opened in a direction away from the connecting shaft 24 .

[0107] Specifically, a guide channel 201 is formed in the top opening 200 for the circulation of liquid. The top opening 200 is provided with a guide port 202, which is connected to the guide channel 201. The guide port 202 is arranged at the end of the top opening 200. The cross-section of the guide port 202 is inclined, and the inclined surface is inclined in the direction away from the connecting shaft 24 of the installation shielding structure 23, such as Figure 3 and Figure 6 As shown, the shielding structure 23 is rotatably connected to one side of the inner cover body 25 of the liquid dispenser cover body 2 through the connecting shaft 24, and as shown in FIG. Figure 8-Figure 12 As shown, the shielding structure 23 is movably connected to one side of the inner cover body 25 of the liquid outlet cover body 2 through the mounting seat 28 and the spring, and a push-up member 200 can be provided to move vertically upward to push open the shielding structure 23, the connecting shaft 24 is located on the left side of the inner cover body 25 of the liquid outlet cover body 2, and the inclination direction of the guide port 202 is downward from left to right, and the guide port 202 is open toward the liquid outlet 21, so that the two can be connected.

[0108] Among them, the main body of the equipment can be a washing machine, and the tip side of the guide port 202 of the top opening member 200 pushes open the shielding structure 23, so that the shielding structure 23 rotates counterclockwise around the rotation axis to open the liquid outlet 21, or the top opening member 200 pushes the shielding structure 23 to move upward to open the liquid outlet 21, and the liquid outlet 21 is connected to the guide port 202, and the laundry liquid in the liquid discharger 100 is introduced into the guide channel 201 from the guide port 202 to realize the delivery of the laundry liquid. The cross-section of the guide port 202 is constructed as an inclined surface, so that the top opening member 200 can push the shielding structure 23 to move while the liquid can flow into the guide channel 201, thereby making the delivery of the liquid more convenient.

[0109] In addition, the liquid discharger 100 in this embodiment also stores a variety of liquids such as laundry detergent and sterilizing liquid, so as to realize the delivery of a variety of liquids. After the liquid discharge is completed, the shielding structure 23 can be automatically reset through the pre-tightening member 22 to reduce the outflow of liquids such as laundry detergent or sterilizing liquid. Since the laundry detergent and sterilizing liquid are relatively viscous and difficult to clean, the cleaning work of the liquid can be reduced by reducing the amount of liquid spillage. The liquid discharger 100 is suitable for being connected to different types of equipment and suitable for different liquid discharge fields. It has a wider range of applications and a good use effect.
