[0002] Water dispensers are a small household appliance commonly used in people's daily lives. They can be used to store water, boil water, collect water, etc., especially heating water dispensers, which are loved by many consumers because they can heat water to a preset temperature as needed. The water-taking operation switches of existing water dispensers mainly include dial-key type, pressure plate type and knob type: the dial-key type controls the water outlet state of the faucet through a manually operable dial-key; the pressure plate type uses a manually operable protruding pressure plate to lock the water outlet, and the water outlet state is controlled by pressing the pressure plate while pressing the water outlet key; the knob type controls the water outlet state of the faucet through a manually rotatable knob. However, existing water-taking operation switches of this type cannot control the water outlet flow, or even if they can control it, they do not have a good control effect, the control structure is complex, and the control operation is inconvenient.

[0006] The water dispenser in this application also has the following additional technical features:

[0007] The inner wall of the shell is provided with a guiding slope, which extends around the circumference of the water inlet and gradually rises along the first direction. During the rotation of the valve core structure along the first direction, the valve core structure slides along the guiding slope and gradually moves away from the water inlet.

[0008] The guide slope is provided with a water outlet limiting boss at a high position along the first direction, the shell is provided with a water cut-off limiting boss at a low position close to the guide slope, and the valve core structure is provided with a limiting protrusion. During the rotation of the valve core structure along the first direction, the limiting protrusion cooperates with the stopper of the water outlet limiting boss and the valve core structure is stopped by the limiting protrusion cooperating with the stopper of the water cut-off limiting boss. During the rotation of the valve core structure along the second direction, the limiting protrusion cooperates with the stopper of the water cut-off limiting boss.

[0009] The valve core structure is provided with a convex point extending toward the guiding inclined surface, and the valve core structure slides along the guiding inclined surface through the convex point during the rotation process.

[0010] The valve core structure includes a valve core body and a valve core end cover, and the valve core end cover includes a cover body and a sealing member. The cover body is installed at one end of the valve core body close to the water inlet, and the sealing member is installed on the cover body, so that the valve core structure closes the water inlet through the sealing member.

[0011] An elastic member is arranged between the cover body and the valve core body, and the elastic member is squeezed into a compressed state by the cover body and the valve core body, so that when the valve core structure is located at the water cut-off position, the elastic member applies a thrust toward the cover body to make the sealing member seal the water inlet.

[0012] The shell is provided with an installation port connected to the water outlet chamber, the installation port and the water inlet are respectively arranged at two opposite sides of the water outlet chamber, the valve core structure is installed in the water outlet chamber through the installation port, a limiting cover plate is installed in the installation port, and the valve core structure is stopped by cooperating with the stopper of the limiting cover plate during the rotation along the first direction.

[0013] The limit cover plate is provided with a through hole, the valve core structure is provided with an operating rod, the operating rod extends to the outside of the shell through the through hole, and a knob is installed at the outer end of the operating rod.

[0014] The water outlet is located at the bottom of the shell and extends downward, and the knob is higher than the water outlet end at the bottom of the water outlet as a whole.

[0015] The operating rod sleeve is provided with a first sealing ring, and the through hole is sealed by the first sealing ring when the valve core structure is located at the water outlet position; and / or a second sealing ring is provided between the limit cover plate and the housing.

[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are:

[0017] 1. The water dispenser provided in the present application is provided with a flow control and water intake structure installed on the body, wherein the valve core structure can rotate from the water cut-off position to the water outlet position by rotating in a first direction, so that the water dispenser can discharge by transporting water to the water inlet and reaching the water outlet through the water passage, and the valve core structure can rotate from the water outlet position to the water cut-off position by rotating in a second direction, so that the flow control and water intake structure closes the water passage and cuts off the water outlet state. Therefore, the present scheme realizes the rotary water outlet state control, and the user only needs to operate the control valve core structure to rotate to control the water outlet and water stop of the water dispenser; wherein, the water passage is gradually enlarged during the rotation of the valve core structure in the first direction, and the enlargement of the water passage makes the water outlet flow rate of the flow control and water intake structure larger per unit time. Therefore, the water flow rate increases with the increase of the rotation angle of the valve core structure in the first direction, and decreases with the decrease of the rotation angle of the valve core structure in the first direction, so as to meet the water intake requirements of different flow rates.

[0018] 2. As a preferred embodiment of the present application, the guiding slope extends around the circumference of the water inlet, and the first direction and the second direction can be set as two opposite directions on the circumference of the water inlet. During the rotation of the valve core structure along the first direction, it slides along the guiding slope. Since the guiding slope gradually rises along the first direction, the valve core structure will gradually move away from the position of the water inlet during the sliding process along the guiding slope. Since the valve core structure closes the water inlet at the water cut-off position, as the valve core structure gradually moves away from the water inlet, the water inlet will be opened and the water passage will gradually increase. Therefore, the size of the water passage is changed by the guiding effect of the guiding slope on the rotation process of the valve core structure. The structure is simple and the use effect is improved.

[0019] 3. As a preferred embodiment of the present application, a water outlet limit boss is provided at a high position of the guide slope along the first direction, a water cut-off limit boss is provided at a low position of the shell body close to the guide slope, and a limit boss is provided on the valve core structure. When the valve core structure rotates along the first direction until it abuts against the water outlet limit boss, it is restricted from continuing to rotate along the first direction, so that the valve core structure cannot rotate endlessly in the first direction, thereby improving the control effect on the water outlet flow rate. When the valve core structure rotates along the second direction until it abuts against the water cut-off limit boss, it is restricted from continuing to rotate in the second direction, so that the valve core structure cannot rotate endlessly in the second direction, thereby ensuring that the valve core structure can rotate back and forth along the first direction and the second direction reliably and effectively.

[0020] 4. As a preferred embodiment of the present application, the valve core end cover includes a cover body and a sealing member. The cover body serves as a structural support for the assembly and positioning of the sealing member. The water inlet is sealed by the sealing member, thereby effectively improving the sealing effect of the valve core structure on the water inlet in a closed state and reducing the risk of leakage and dripping in the flow control and water intake structure.

[0021] 5. As a preferred embodiment of the present application, one function of the limit cover plate is to close the installation port after the valve core structure is installed in the water outlet chamber through the installation port to prevent water leakage at the installation port. Another function is to stop and limit the valve core structure after the valve core structure rotates a certain angle along the first direction to prevent the valve core structure from detaching from the guide slope.

[0022] 6. As a preferred embodiment of the present application, the water outlet is located at the bottom of the shell and extends downward. The knob is higher than the water outlet end at the bottom of the water outlet as a whole, so that the knob is above the water outlet position at the bottom of the water outlet. When the user takes water, he only needs to place the cup under the water outlet and rotate the knob above the water outlet position with his hand to take water. When hot water is coming out, the human hand does not need to be under the water outlet end and is far away from the hot water, thereby reducing the risk of hot water splashing towards the human hand.

[0040] In the embodiment of the present application, a water dispenser is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all explained on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation on the technical solution provided in the present application.

[0041] Reference Figures 1 to 8 As shown, a water dispenser provided in the present application comprises a body 1 and a flow control and water intake structure 2 for controlling water outlet, the flow control and water intake structure 2 comprising a shell 21 and a valve core structure 22, the shell 21 is provided with a water outlet chamber 211 and a water inlet 212 and a water outlet 213 respectively connected to the water outlet chamber 211, the valve core structure 22 is arranged in the water outlet chamber 211 and can rotate from a water cut-off position to a water outlet position along a first direction or rotate from the water outlet position to the water cut-off position along a second direction opposite to the first direction; at the water cut-off position, the valve core structure 22 closes the water inlet 212; at the water outlet position, the valve core structure 22 cooperates with the shell 21 to form a water passage 23 connecting the water inlet 212 with the water outlet 213, and the water passage 23 is gradually enlarged during the rotation of the valve core structure 22 along the first direction. Figure 3 The figure shows the state when the valve core structure 22 is located at the water cut-off position. Figure 4 The figure shows the state when the valve core structure 22 is located at the water outlet position.

[0042] In the water dispenser provided in the present application, the flow control water intake structure 2 can be used as the water outlet structure of the water dispenser, and the water inlet 212 can be connected to the water supply structure of the water dispenser, wherein the water supply structure can be a cold water storage structure, such as bottled water, cold water tank, etc., and the water supply structure can also be a heating device, instant heating device, insulation device, etc. that can output hot water. The water outlet 213 can be used to directly output water to the user end, and can also be connected to a faucet to output water to the user end through the faucet. Figure 1As shown, a plurality of flow control and water intake structures 2 can be installed on the machine body 1, and the plurality of flow control and water intake structures 2 can be used to discharge water of different temperatures or different types of water, etc., so as to realize separate control of water flows of different types or temperatures and synchronized water discharge. Among them, the valve core structure 22 can rotate from the water cut-off position to the water outlet position along the first direction, so that the water dispenser can discharge water by conveying water to the water inlet 212 and reaching the water outlet 213 through the water passage 23. The valve core structure 22 can rotate from the water outlet position to the water cut-off position along the second direction, so that the flow control and water intake structure 2 closes the water passage 23 and cuts off the water discharge state. For example, the first direction can be the direction in which the valve core structure 22 rotates clockwise relative to the machine body 1, and the second direction is the direction in which the valve core structure 22 rotates counterclockwise relative to the machine body 1. direction, this solution realizes rotary water outlet state control, and the user only needs to operate the control valve core structure 22 to rotate to control the water outlet and water stop of the water dispenser; wherein, the water passage 23 is gradually enlarged during the rotation of the valve core structure 22 along the first direction, and the increase of the water passage 23 makes the water outlet flow rate of the flow control water intake structure 2 larger per unit time. Therefore, the water flow rate increases with the increase of the rotation angle of the valve core structure 22 along the first direction, and decreases with the decrease of the rotation angle of the valve core structure 22 along the first direction, thereby meeting the water intake requirements of different flow rates.

[0043] Regarding the method of gradually enlarging the water passage 23 formed during the rotation of the valve core structure 22 along the first direction, as a preferred embodiment of the present application, as shown in FIG. Figures 2 to 8 As shown, the inner wall of the housing 21 is provided with a guiding slope 214, the guiding slope 214 extends around the circumference of the water inlet 212 and gradually rises along the first direction, and the valve core structure 22 slides along the guiding slope 214 and gradually moves away from the water inlet 212 during the rotation along the first direction. It can be understood by those skilled in the art that the guiding slope 214 extends around the circumference of the water inlet 212, and the first direction and the second direction can be set as two opposite directions on the circumference of the water inlet 212. Figure 7The first direction X and the second direction Y are schematically illustrated in the figure. During the rotation of the valve core structure 22 along the first direction, it slides along the guiding slope 214. Since the guiding slope 214 gradually rises along the first direction, the valve core structure 22 will gradually move away from the position of the water inlet 212 during the sliding process along the guiding slope 214. Since the valve core structure 22 closes the water inlet 212 at the water-off position, as the valve core structure 22 gradually moves away from the water inlet 212, the water inlet 212 will be opened and the water passage 23 will gradually increase. Similarly, when the valve core structure 22 rotates along the second direction, the valve core structure 22 will gradually approach the water inlet 212 and the water passage 23 will gradually shrink until the water passage 23 is closed when the valve core is at the water-off position. Therefore, the size of the water passage 23 is changed by the guiding effect of the guiding slope 214 on the rotation process of the valve core structure 22. The structure is simple and the use effect is improved.

[0044] In a preferred embodiment, to ensure the rotation reliability of the valve core structure 22, as Figure 5 and Figure 6 As shown, two or more guiding inclined surfaces 214 are arranged at intervals around the water inlet 212 in the circumferential direction, and correspondingly, two or more limiting protrusions 221 are arranged on the valve core structure 22 .

[0045] In other embodiments, the water passage may be gradually enlarged during the rotation of the valve core structure along the first direction by other means. For example, a spiral guide groove may be provided on the inner wall of the water outlet chamber, and the valve core structure may be provided with a guide protrusion adapted to the guide groove. When the valve core structure rotates along the first direction or the second direction, the guide protrusion slides along the guide groove to guide the valve core structure away from or close to the water inlet, thereby achieving the gradual enlargement or reduction of the water passage.

[0046] As a preferred embodiment, Figures 5 to 8 As shown, the guide slope 214 is provided with a water outlet limiting boss 215 at a high position along the first direction, the housing 21 is provided with a water cut-off limiting boss 216 at a low position close to the guide slope 214, and the valve core structure 22 is provided with a limiting convex block 221. During the rotation of the valve core structure 22 along the first direction, the limiting convex block 221 is stopped by the stopper cooperation of the water outlet limiting boss 215, and during the rotation of the valve core structure 22 along the second direction, the limiting convex block 221 is stopped by the stopper cooperation of the water cut-off limiting boss 216. Specifically, Figure 8 The valve core structure 22 is shown as rotating to a position against the water outlet limiting boss 215. At this time, the valve core structure 22 is located at a high position of the guide slope 214 relative to the water inlet 212, and the water passage 23 reaches the maximum, which can achieve the maximum flow rate of water outlet. Figure 7It is shown that the valve core structure 22 rotates to a position against the water cut-off limiting boss 216. At this time, the valve core structure 22 is separated from the guiding inclined surface 214, and the water inlet 212 is closed, so that the flow control and water intake structure 2 stops discharging water. Those skilled in the art can understand that a water outlet limit boss 215 is provided at a high position of the guide slope 214 along the first direction, a water cut-off limit boss 216 is provided at a low position of the shell 21 close to the guide slope 214, and a limit boss 221 is provided at the valve core structure 22. When the valve core structure 22 rotates along the first direction until it abuts against the water outlet limit boss 215, it is restricted from continuing to rotate along the first direction, so that the valve core structure 22 cannot rotate endlessly in the first direction, thereby improving the control effect on the water outlet flow rate. When the valve core structure 22 rotates along the second direction until it abuts against the water cut-off limit boss 216, it is restricted from continuing to rotate in the second direction, so that the valve core structure 22 cannot rotate endlessly in the second direction, thereby ensuring that the valve core structure 22 can rotate back and forth along the first direction and the second direction reliably and effectively.

[0047] As a preferred embodiment, Figure 2 , Figure 3 and Figure 6 As shown, the valve core structure 22 is provided with a convex point 222 extending toward the guide inclined surface 214, and the valve core structure 22 slides along the guide inclined surface 214 through the convex point 222 during the rotation process. It can be understood by those skilled in the art that the valve core structure 22 contacts the guide inclined surface 214 through the convex point 222, and slides along the guide inclined surface 214 through the convex point 222 during the rotation process, which greatly reduces the contact area between the valve core structure 22 and the guide inclined surface 214, thereby effectively reducing the friction resistance from the guide inclined surface 214 during the rotation process of the valve core structure 22, improving the rotation feel of the valve core structure 22, and making the rotation process more labor-saving.

[0048] Regarding the position maintenance method of the valve core structure 22 on the guide slope 214, in a specific embodiment, it can be set to be manually maintained, in other words, the user is required to hold the knob 25 to maintain the position of the valve core structure 22, so that the position of the valve core structure 22 will not automatically rotate; in another specific embodiment, the pressure between the protrusion 222 and the guide slope 214 can also be increased, so that the position of the valve core structure 22 can be maintained by the friction force generated by the guide slope 214 on the protrusion 222, so that the user can let go of the knob 25 after rotating it to the desired position; in other embodiments, pits arranged at intervals can be set on the guide slope 214 along the first direction, the pits are adapted to the protrusions 222, each pit is equivalent to a water flow control gear, the protrusion 222 cooperates with different pits to make the water passage 23 different in size, thereby making the water flow different, and the protrusion 222 cooperates with the pits to limit the valve core structure 22, thereby maintaining the position of the valve core structure 22, so that the user can let go of the knob 25 after rotating it to the desired position.

[0049] Regarding the specific form of the valve core structure 22, as a preferred embodiment of the present application, as shown in Figure 2 , Figure 3 and Figure 6 As shown, the valve core structure 22 includes a valve core body 223 and a valve core end cover 224, and the valve core end cover 224 includes a cover body 2241 and a sealing member 2242. The cover body 2241 is installed at one end of the valve core body 223 close to the water inlet 212, and the sealing member 2242 is installed on the cover body 2241, so that the valve core structure 22 closes the water inlet 212 through the sealing member 2242. The cover body 2241 plays a structural support role in the assembly and positioning of the sealing member 2242, and closes the water inlet 212 by the sealing member, effectively improving the sealing effect of the valve core structure 22 on the water inlet 212 in the closed state, and reducing the risk of leakage and dripping of the flow control water intake structure 2. The present application does not limit the installation method of the cover body 2241 and the valve core body 223. The cover body 2241 can be snap-connected with the valve core body 223, or it can be fixed by interference fit or ultrasonic welding. The sealing body can be embedded in the installation hole set in the center of the cover body 2241, and the sealing member 2242 can be made of a silicone structure or other suitable structures.

[0050] Furthermore, if Figure 2 As shown, an elastic member 225 is provided between the cover body 2241 and the valve core body 223, and the elastic member 225 is squeezed into a compressed state by the cover body 2241 and the valve core body 223, so that when the valve core structure 22 is located at the water cut-off position, the elastic member 225 applies a thrust toward the cover body 2241 to make the sealing member 2242 seal the water inlet 212. Since the elastic member 225 is squeezed into a compressed state by the cover body 2241 and the valve core body 223, the elastic member 225 will always apply a reverse thrust to the cover body 2241, which can prevent the cover body 2241 from deforming toward the side where the elastic member 225 is located. When the valve core structure 22 is located at the water cut-off position, the thrust applied by the elastic member 225 to the cover body 2241 will drive the cover body 2241 to be close to the edge of the water inlet 212 through the sealing member 2242, thereby improving the sealing of the water inlet 212 and effectively reducing the risk of water leakage. Specifically, the elastic member 225 can be selected from Figure 2 The spring structure shown in .

[0051] As a preferred implementation of the present application, Figures 2 to 4As shown, the housing 21 is provided with an installation port 217 communicating with the water outlet chamber 211, the installation port 217 and the water inlet 212 are respectively arranged at two opposite sides of the water outlet chamber 211, the valve core structure 22 is installed in the water outlet chamber 211 through the installation port 217, a limit cover plate 24 is installed in the installation port 217, and the valve core structure 22 is stopped by cooperating with the stopper of the limit cover plate 24 during the rotation along the first direction. By arranging the installation port 217 on the side opposite to the water inlet 212, it is convenient for the valve core structure 22 to be installed in the water outlet chamber 211 through the installation port 217 directly toward the direction where the water inlet 212 is located. One function of the position-limiting cover plate 24 is to close the installation opening 217 after the valve core structure 22 is installed in the water outlet chamber 211 through the installation opening 217 to prevent water leakage at the installation opening 217. Another function is to stop and limit the valve core structure 22 after the valve core structure 22 rotates a certain angle along the first direction to prevent the valve core structure 22 from separating from the guiding inclined surface 214. In a specific embodiment, the position-limiting cover plate 24 can be clamped in the installation opening 217 or screwed in the installation opening 217. Of course, other suitable methods can also be used for assembly.

[0052] Furthermore, if Figure 2 , Figure 3 and Figure 6 As shown, the limit cover plate 24 is provided with a through hole 241, and the valve core structure 22 is provided with an operating rod 226. The operating rod 226 extends to the outside of the housing 21 through the through hole 241, and a knob 25 is installed at the outer end of the operating rod 226. Through this arrangement, a convenient knob 25 operation is achieved, which improves practicality.

[0053] In a preferred embodiment, Figure 1 and Figure 2 As shown, the water outlet 213 is located at the bottom of the shell 21 and extends downward, and the knob 25 is higher than the water outlet end at the bottom of the water outlet 213 as a whole, so that the knob 25 is above the water outlet position at the bottom of the water outlet 213. When the user takes water, he only needs to place the water cup under the water outlet 213, and rotate the knob 25 above the water outlet position with his hand to take water. When hot water is discharged, the human hand does not need to be under the water outlet end, and is far away from the hot water, thereby reducing the risk of hot water splashing towards the human hand.

[0054] In a preferred embodiment, Figure 2 and Figure 4 As shown, the operating rod 226 is sleeved with a first sealing ring 26 . When the valve core structure 22 is located at the water outlet position, the through hole 241 is sealed by the first sealing ring 26 , thereby effectively preventing water entering the water outlet cavity 211 from leaking through the through hole 241 .
