Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drinking water equipment, concretely relates to a water outlet valve, a container and a drinking water equipment. BACKGROUND

[0002] In the related art drinking water equipment, a detachable container body is arranged in the machine body, the bottom of the container body is provided with a water outlet, and a water outlet valve is arranged at the water outlet. A thimble is arranged in the machine body. When the container body is placed in the machine body, the thimble will normally push open the valve core of the water outlet valve, facilitating the water pump to draw liquid in the container body through the water outlet valve, supply water to the water outlet nozzle of the machine body, and reset the valve core when the container body is lifted away from the machine body, and the water outlet valve is automatically closed. However, in some cases, the valve core may deviate due to the superposition of thimble pressure and tolerance factors, and occasionally the motion trajectory may deviate greatly from the set trajectory, and the valve core may not be automatically reset and continuously leak. SUMMARY

[0003] Therefore, the utility model aims to provide a water outlet valve, a container and a drinking water equipment, which can reduce the probability of water leakage of the water outlet valve.

[0004] The first aspect embodiment of the utility model provides a water outlet valve, which comprises: a valve body, the valve body having a water outlet channel therein; a valve core, movably arranged in the water outlet channel and capable of moving along the length direction of the water outlet channel to open and close the water outlet channel; a plurality of limiting ribs are arranged on the inner wall surface of the water outlet channel, and the plurality of limiting ribs are distributed in a circumferential direction of the water outlet channel at intervals, and are used for limiting the movement range of the valve core in the radial direction of the water outlet channel.

[0005] The water outlet valve provided by the embodiment of the present application can limit the valve core from moving greatly in the radial direction of the water outlet channel by arranging limiting ribs on the inner wall surface of the water outlet channel and distributing the limiting ribs in the circumferential direction of the water outlet channel at intervals. When the valve core is lifted, the limiting ribs can limit the valve core from moving greatly in the radial direction of the water outlet channel, and can prevent the valve core from deviating greatly, thereby reducing the probability of water leakage of the water outlet valve due to the valve core deviating greatly and failing to reset.

[0006] Further, in some embodiments, the plurality of limiting ribs are evenly distributed in the circumferential direction of the inner wall surface of the water outlet channel; and / or the number of limiting ribs is greater than or equal to three.

[0007] In these embodiments, the plurality of limiting ribs are evenly distributed in the circumferential direction of the inner wall surface, which can limit the movement range of the valve core in multiple circumferential points, and the limiting effect is good. The number of limiting ribs is at least three, which can ensure that the valve core can be blocked by the limiting ribs when it approaches the inner wall surface in any direction, and the limiting effect is ensured.

[0008] Further, in some embodiments, the water outlet valve further comprises a reset spring for keeping the valve core in a state of closing the water outlet channel, the reset spring being a conical coil spring, and a small end of the reset spring abutting against the valve core. Here, the reset spring is used to apply pressure to the valve core to close the water outlet channel, and the closing effect is good.

[0009] In these embodiments, the reset spring is used to apply pressure to the valve core to close the water outlet channel, and the closing effect is good. Moreover, the reset spring is generally inverted conical, with a large end thereof upwardly abutting against the valve body or other components, and a small end thereof abutting against the valve core, which can increase the contact area between the reset spring and the abutting surface, and is conducive to the reset spring being stressed more uniformly when the valve core is lifted by the valve rod. Meanwhile, when the valve core moves upwardly to press the reset spring, the overall stress center of the reset spring is closer to the center of the water outlet channel, which can avoid lateral deviation or inclination of the reset spring caused by eccentric stress, and is conducive to the reset spring accurately resetting the valve core to avoid water leakage of the water outlet valve due to deviation of the valve core.

[0010] Further, in some embodiments, the plurality of limiting ribs extend along the length direction of the water outlet channel and extend to the outer periphery of the reset spring. In this way, the limiting ribs not only limit the valve core, but also limit the reset spring, which can prevent the reset spring from being greatly deviated and inclined, thereby helping the valve core to be accurately reset to close the water outlet channel under the elastic force of the reset spring.

[0011] Further, in some embodiments, the valve core is arranged close to a first end of the water outlet channel, the reset spring is arranged close to a second end of the water outlet channel, the limiting ribs include first segment limiting ribs and second segment limiting ribs distributed along the length direction of the valve body, the first segment limiting ribs correspond to the movement range of the valve core in the length direction of the water outlet channel, and the second segment limiting ribs surround the outer periphery of the reset spring; in the direction from the first end to the second end, the opening area of the space surrounded by the plurality of first segment limiting ribs remains consistent or gradually increases, and the opening area of the space surrounded by the plurality of second segment limiting ribs gradually increases.

[0012] In these embodiments, the opening area of the space surrounded by the first segment limiting ribs of the plurality of limiting ribs remains consistent from the first end to the second end of the water outlet channel, which can well limit the valve core and ensure that the valve core moves almost along the center of the water outlet channel. Of course, the opening area of the space surrounded by the first segment limiting ribs of the plurality of limiting ribs can gradually increase from the first end to the second end, which facilitates demolding when the valve body is formed by injection molding. In addition, the second segment limiting ribs of the plurality of limiting ribs can be designed in the shape of the inverted conical reset spring, which can well limit the reset spring, and facilitates demolding when the valve body is formed by injection molding.

[0013] Further, in some embodiments, the water outlet valve further comprises a filter screen covering the top of the valve body, and the big end of the return spring abuts against the filter screen. In this way, the filter screen can be used to filter the liquid entering the water outlet channel, and the return spring can abut against the filter screen to apply pressure to the valve core.

[0014] Further, in some embodiments, the water outlet valve further comprises a positioning member arranged on the side of the filter screen facing the valve core, and the top of the return spring is sleeved on the outer periphery of the positioning member. In this way, the positioning member can be used to limit the top end of the return spring, so as to avoid the return spring from deviating greatly and affecting the accurate pushing of the valve core, thereby avoiding water leakage due to the water outlet valve not being tightly closed. Moreover, compared with installing the positioning member on the valve body, installing the positioning member on the filter screen does not need to change the structure of the valve body, which is convenient for valve body processing and assembly.

[0015] Further, in some embodiments, the valve body is formed by metal powder injection molding, and the outer periphery of the valve body comprises a first segment of outer periphery, a transition surface and a second segment of outer periphery connected in sequence from the first end of the water outlet channel to the second end of the water outlet channel; wherein the outer diameter of the second segment of outer periphery is greater than that of the first segment of outer periphery, the second segment of outer periphery is provided with a connecting structure for installation and positioning of the water outlet valve, and the transition surface is an inclined surface.

[0016] In these embodiments, the valve body is formed by metal powder injection molding, compared with the valve body being a plastic part in the related art, which is soaked in boiling water for a long time and has the risk of aging and water leakage, the valve body made of metal material will not deform in a high temperature environment, which can effectively ensure the installation and sealing of the valve body and avoid water leakage. Moreover, the metal material is more hygienic and has a longer service life, which can effectively ensure the hygiene during use. In addition, the metal material has high strength and good toughness, and is not easy to be damaged even after long-term and frequent use, which can significantly prolong the service life of the product and reduce the frequency and cost of replacing the product for the user.

[0017] Of course, the valve body is formed by metal powder injection molding, which is convenient for processing and saves materials and costs. However, the flow state of the metal powder is not good at the position of the stepped surface, which is easy to cause process pores, which will cause a certain risk of water leakage of the valve body. Therefore, in these embodiments, the inclined surface is used to transition between the first segment of outer periphery and the second segment of outer periphery with different thicknesses, instead of the stepped surface, which is beneficial to optimize the flow state of the metal powder during injection molding, so as to avoid the occurrence of process pores and the resulting water leakage of the valve body.

[0018] Further, in some embodiments, the connecting structure is an external thread, and the water outlet valve further comprises a connecting nut, an inner side wall of the connecting nut having an internal thread matched with the external thread. The outer periphery of the valve body further has a protruding limiting platform, the limiting platform being close to the second end of the water outlet channel relative to the second segment outer periphery surface.

[0019] In this way, when the water outlet valve is installed at the water outlet opening on the bottom wall of the container body, the water outlet valve can be inserted into the water outlet opening from top to bottom, and the connecting nut can be sleeved on the outer periphery of the water outlet valve from below and screwed on the external thread, so as to clamp the wall surface around the water outlet opening between the connecting nut and the limiting platform of the valve body. Compared with the prior art in which the valve body is a plastic part and the installation and positioning of the water outlet valve are achieved by using a plastic clamping jaw, the connecting nut has good fastening performance and can improve the sealing performance between the water outlet valve and the water outlet opening. Moreover, even if it is placed in a high-temperature environment for a long time, the connecting nut can maintain the locking force, and the probability of water leakage at the water outlet valve can be reduced.

[0020] The second aspect embodiment of the utility model provides a kind of container, container includes: container body, water outlet is provided on the bottom wall of container body;The water outlet valve of any one of the above embodiments, water outlet valve is arranged at water outlet.

[0021] The container provided by the embodiments of the present application has the water outlet valve of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0022] The third aspect embodiment of the utility model provides a kind of drinking water equipment, drinking water equipment includes: the container proposed in the above second aspect embodiment.

[0023] The drinking water equipment provided by the embodiments of the present application has the container of any one of the above embodiments, and thus has the beneficial effects of any one of the above embodiments, which will not be repeated here.

[0024] Further, in some embodiments, the drinking water equipment further comprises: a machine body, an outer side of the machine body is provided with a water outlet nozzle, an inner part of the machine body has a containing cavity, and the container is detachably placed in the containing cavity;A valve core lifting piece is arranged in the middle part of the bottom of the containing cavity, and when the container is placed in the containing cavity, the valve core lifting piece lifts the valve core of the water outlet valve to open the water outlet channel.

[0025] In these embodiments, the container is detachably placed in the containing cavity, which facilitates separate removal of the container for water filling, cleaning and other operations. Moreover, after the container is placed in the containing cavity, the valve core of the water outlet valve can be lifted by the valve core lifting piece at the bottom of the containing cavity, so as to open the water outlet valve and facilitate the drinking water equipment to draw liquid from the container body.

[0054] The embodiments of the present application will be described below in conjunction with Figures 1 to 14 The embodiments of the present application will be described below in conjunction with

[0055] As Figures 1 to 6As shown, the first aspect embodiment of the utility model provides a water outlet valve 100, water outlet valve 100 includes: valve body 110, the water outlet channel 111 is arranged in valve body 110; Valve core 120, movably set in water outlet channel 111, and can be moved along the length direction of water outlet channel 111 to open and close water outlet channel 111;The inner wall surface of water outlet channel 111 is provided with a plurality of limit ribs 112, and the plurality of limit ribs 112 is distributed along the circumferential direction of water outlet channel 111, and is used for limiting the activity range of valve core 120 in the radial direction of water outlet channel 111.

[0056] The water outlet valve 100 provided by the embodiment of the present aspect, by setting the limit rib 112 on the inner wall surface of the water outlet channel 111, and making the limit rib 112 be distributed in the circumferential direction of the water outlet channel 111, when the valve core 120 is lifted, the limit rib 112 can limit the valve core 120 to move greatly in the radial direction of the water outlet channel 111, and can prevent the valve core 120 from moving greatly, thereby reducing the probability of water leakage of the water outlet valve 100 due to the valve core 120 moving greatly and unable to reset.

[0057] Further, as shown, Figures 4 to 6 The plurality of limit ribs 112 can be uniformly distributed along the circumferential direction of the inner wall surface of the water outlet channel 111, and / or the number of limit ribs 112 is greater than or equal to three. In this way, the plurality of limit ribs 112 can limit the movement range of the valve core 120 in the circumferential direction, and the limiting effect is good. Moreover, making the number of limit ribs 112 be at least three can ensure that when the valve core 120 approaches the inner wall surface in any direction, it can be blocked and limited by the limit rib 112, and the limiting effect is ensured.

[0058] As an example, the number of limit ribs 112 can be four, five or six.

[0059] As an example, the plurality of limit ribs 112 can be distributed symmetrically along the center line of the water outlet channel 111.

[0060] Further, as shown, Figure 2 And Figure 3 The water outlet valve can further include: a reset spring 140 for keeping the valve core 120 in a state of closing the water outlet channel 111, the reset spring 140 is a conical spiral spring, and the small end of the reset spring 140 abuts against the valve core 120.

[0061] The reset spring 140 is used to apply pressure to the valve core 120 to close the water outlet passage 111 of the water outlet valve 100, and the closing effect is good. Moreover, the reset spring 140 is generally inverted conical, and the large end is upwardly abutted with the valve body 110 or other components, and the small end is abutted with the valve core 120, which can increase the contact area of the reset spring 140 and the abutting surface, and is beneficial to the reset spring 140 to bear force more uniformly when the valve core 120 is lifted by the valve rod. When the valve core 120 moves upwardly to press the spring, the overall force center of gravity of the reset spring 140 is closer to the center of the water outlet passage 111, which can avoid the lateral deviation or inclination of the reset spring 140 caused by eccentric force, and then is beneficial to the reset spring 140 to accurately reset the valve core 120 when the valve core 120 is reset, and avoids the water leakage of the water outlet valve 100 due to the deviation of the valve core 120.

[0062] Further, as shown in Figure 2 and Figure 3 , the water outlet valve can further include a valve sealing member 130 arranged in the water outlet passage 111 and located on the side of the valve core 120 away from the reset spring 140. The valve core 120 can be pressed against the valve sealing member 130 under the elastic force of the reset spring 140 to close the water outlet passage 111, and then the water outlet valve 100 is closed. The valve core 120 can also be lifted away from the valve sealing member 130 to open the water outlet passage 111, and then the water outlet valve 100 is opened. The design of the valve sealing member 130 is beneficial to the valve core 120 to tightly close the water outlet passage 111.

[0063] As an example, as shown in Figure 2 and Figure 3 , the valve sealing member 130 is a silica gel sealing ring, which is fixed inside the valve body 110 and distributed circumferentially along the inner wall surface of the water outlet passage 111. The valve sealing member 130 can be in full abutment with the valve core 120 to close the water outlet passage 111, and can also allow the liquid to flow out smoothly through the channel surrounded by the valve sealing member 130 when the valve core 120 is lifted.

[0064] As an example, as shown in Figure 2 and Figure 3 , the valve core 120 is spherical, for example, a steel ball, and the valve core 120 can be tightly fitted with the valve sealing ring in the circumferential direction, and the closing effect is good when the water outlet valve 100 is in the closed state. Of course, the valve core 120 can also be block-shaped or plate-shaped, and the like, which are not listed here.

[0065] Further, as shown in Figure 2 and Figure 3As shown, the plurality of limiting ribs 112 can extend along the length direction of the water outlet channel 111 and extend to the outer periphery of the reset spring 140. With this design, the limiting ribs 112 can not only limit the spool 120, but also limit the reset spring 140, which can prevent the reset spring 140 from being greatly skewed and offset, thereby helping the spool 120 to be accurately reset to close the water outlet channel 111 under the elastic force of the reset spring 140.

[0066] As an example, as shown in Figure 3 and Figure 8 The spool 120 is arranged near the first end of the water outlet channel 111, the reset spring 140 is arranged near the second end of the water outlet channel 111, the limiting ribs 112 include first segment limiting ribs 1121 distributed in the length direction of the valve body 110 and second segment limiting ribs 1122, the first segment limiting ribs 1121 correspond to the movement range of the spool 120 in the length direction of the water outlet channel 111, and the second segment limiting ribs 1122 surround the outer periphery of the reset spring 140; in the direction from the first end to the second end, the opening area of the space surrounded by the plurality of first segment limiting ribs 1121 remains consistent or gradually increases, and the opening area of the space surrounded by the plurality of second segment limiting ribs 1122 gradually increases.

[0067] Here, the opening area of the space surrounded by the first segment limiting ribs 1121 of the plurality of limiting ribs 112 remains consistent from top to bottom, which can well limit the spool 120, avoid the spool 120 being lifted higher and offsetting larger, and be beneficial to the spool 120 moving almost along the center of the water outlet channel 111. Of course, the opening area of the space surrounded by the first segment limiting ribs 1121 of the plurality of limiting ribs 112 can also gradually decrease from top to bottom, which facilitates demolding when the valve body 110 is formed by injection molding. In addition, the second segment limiting ribs 1122 of the plurality of limiting ribs 112 can be designed in the shape of the inverted conical reset spring 140, which can well limit the reset spring 140 on the one hand, and facilitate demolding when the valve body 110 is formed by injection molding on the other hand.

[0068] Further, as shown in Figure 2 and Figure 3 The water outlet valve 100 can also include a filter screen 180, the filter screen 180 covers the top of the valve body 110, and the big end of the reset spring 140 abuts against the filter screen 180. With this design, the filter screen 180 can be used to filter the liquid entering the water outlet channel 111, and the reset spring 140 can abut against the filter screen 180, thereby exerting pressure on the spool 120.

[0069] Further, as shown in Figure 2 and Figure 3As shown, the water outlet valve 100 can further include a positioning member 190, which is arranged on the side of the filter screen 180 facing the valve core 120, and the top of the reset spring 140 is sleeved on the outer periphery of the positioning member 190. In this way, the top end of the reset spring 140 can be limited by the positioning member 190, so as to avoid that the reset spring 140 deviates greatly and affects the accurate pushing of the valve core 120, thereby avoiding water leakage due to the water outlet valve 100 not being closed tightly. Moreover, compared with installing the positioning member 190 on the valve body 110, installing the positioning member 190 on the filter screen 180 does not need to change the structure of the valve body 110, which is convenient for processing the valve body 110 and assembling.

[0070] As an example, the positioning member 190 is a positioning block, the top end of the positioning block has a protruding part, the middle part of the filter screen 180 has a mounting hole, the protruding part is inserted into the mounting hole to realize the positioning of the positioning member 190. The positioning member 190 is convenient to assemble. Moreover, the filter screen 180 can be provided with filter holes around the mounting hole in the circumferential direction, so as to facilitate the liquid in the container body 200 to enter the water outlet valve 100 through the filter screen 180 from multiple directions.

[0071] Further, in some embodiments, the valve body 110 is formed by metal powder injection molding. Compared with the valve body 110 being a plastic part in the related art, which is soaked in boiling water for a long time and has the risk of aging and water leakage, the valve body 110 with a metal material will not deform in a high-temperature environment, which can effectively ensure the installation sealing performance of the valve body 110 and avoid water leakage. Moreover, the metal material is more hygienic and has a longer service life, which can effectively ensure the hygiene during use. In addition, the metal material has high strength and good toughness, and is not easy to be damaged even after long-term and frequent use, which can significantly prolong the service life of the product and reduce the frequency and cost of replacing the product for the user.

[0072] Of course, the valve body 110 is formed by metal powder injection molding, which is convenient to process and saves materials and costs. However, the flow state of the metal powder at the stepped surface is not good, which is easy to cause process blowholes, which will cause a certain risk of water leakage of the valve body 110.

[0073] Therefore, in order to avoid water leakage of the water outlet valve 100, further, Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, from the direction from the first end of the water outlet channel 111 to the second end of the water outlet channel 111, the outer periphery of the valve body 110 can include a first segment outer periphery 116, a transition surface 115 and a second segment outer periphery 114 connected in sequence; the outer diameter of the second segment outer periphery 114 is greater than the outer diameter of the first segment outer periphery 116, the second segment outer periphery 114 is provided with a connecting structure 1141 for installation and positioning of the water outlet valve 100, and the transition surface 115 is an inclined surface.

[0074] Here, the second section outer circumferential surface 114 with different thickness and the first section outer circumferential surface 116 are connected by an inclined surface instead of a stepped surface, which is beneficial to optimize the flow state of the metal powder during injection molding, making it more smooth, thereby avoiding the appearance of process pores and the resulting water seepage of the valve body 110. In addition, the connection structure 1141 provided on the thicker second section outer circumferential surface 114 can ensure that this part has sufficient structural strength, thereby facilitating the stable connection of the valve body 110 and the container body 200.

[0075] Of course, the valve body 110 can be processed and formed in other ways, not limited to the above-mentioned injection molding. The valve body 110 can be a stainless steel valve body 110.

[0076] Further, as shown in Figure 2 , Figure 3 and Figure 8 , the connection structure 1141 can be an external thread, and the water outlet valve 100 further includes a connecting nut 150, the inner side wall of the connecting nut 150 having an internal thread matched with the external thread. In addition, the outer circumferential surface of the valve body 110 can also have a protruding limiting platform 113, which is close to the second end of the water outlet passage 111 relative to the second section outer circumferential surface 114.

[0077] In this way, when the water outlet valve 100 is installed at the water outlet 210 on the bottom wall of the container body 200, the water outlet valve 100 can be inserted into the water outlet 210 from top to bottom, and the connecting nut 150 can be sleeved on the outer circumferential surface of the water outlet valve 100 from below and screwed on the external thread, so as to clamp the wall surface around the water outlet 210 between the connecting nut 150 and the limiting platform 113 of the valve body 110. Compared with the prior art in which the valve body 110 is a plastic part and the installation and positioning of the water outlet valve 100 are achieved by using a plastic claw, the connecting nut 150 has good fastening and can improve the sealing between the water outlet valve 100 and the water outlet 210. Moreover, even in a high-temperature environment for a long time, the connecting nut 150 can maintain the locking force and can reduce the probability of water leakage at the water outlet valve 100.

[0078] Moreover, the connecting nut 150 is connected with the valve body 110 in the circumferential direction, and the locking force of the connecting nut 150 on the valve body 110 is distributed more uniformly in the circumferential direction, and the sealing is better. In addition, this threaded connection method greatly improves the convenience of installation. In the production line installation link, workers do not need complex operation skills and tools to quickly complete the installation process of the water outlet valve 100, which greatly shortens the assembly time of a single product, can effectively improve the production efficiency, reduce the overall cost, and improve the production capacity.

[0079] Of course, the connecting structure 1141 can also be a card slot, a card jaw or the like, as long as it can realize the installation and positioning of the water outlet valve 100, and is not limited to the above examples.

[0080] Further, as shown in Figure 2 and Figure 3 , the water outlet valve 100 can also include a gasket 160, which is arranged around the outer periphery of the valve body 110 and between the limiting table 113 and the connecting nut 150. In this way, when the water outlet valve 100 is installed at the water outlet 210 on the bottom wall of the container body 200, the gasket 160 can be used to isolate the wall surface around the water outlet 210 from the connecting nut 150, which can prevent the wall surface around the water outlet 210 from being rubbed during the process of screwing the connecting nut 150, thereby preventing the wall surface around the water outlet 210 from being worn.

[0081] Further, as shown in Figure 2 and Figure 3 , the water outlet valve 100 can also include a sealing member 170, which is arranged around the outer periphery of the valve body 110 and between the limiting table 113 and the gasket 160. In this way, when the water outlet valve 100 is installed at the water outlet 210 on the bottom wall of the container body 200, the sealing member 170 can be used to block the gap between the valve body 110 and the water outlet 210, thereby preventing the water in the container body 200 from leaking out through the gap between the water outlet 210 and the valve body 110, and improving the sealing between the two. Moreover, the sealing member 170 is usually a return spring 140, which is pressed against the limiting table 113 by the connecting nut 150, and can also cause the sealing member 170 to be deformed under pressure, so as to make the sealing member 170 tightly fit the limiting table 113 and the wall surface around the water outlet 210, thereby further improving the sealing effect.

[0082] As shown in Figure 10 , the sealing member 170 is pressed between the wall surface around the water outlet 210 and the limiting table 113, and has good sealing effect.

In this way, the liquid in the container body 200 can flow better to the low-positioned filter screen 180 and flow out through the water outlet 210. Moreover, the filter screen 180 does not protrude conspicuously, and the user can clean the container body 200 without being easily scratched by the filter screen 180.

[0086] Further, in some embodiments, as shown in Figure 9 and Figure 10 , the container further comprises: a heating element 220 arranged at the bottom of the container body 200 and used for heating the liquid in the container body 200; an upper coupler (not shown in the figure) arranged at the bottom of the container body 200 and electrically connected with the heating element 220, and the lower part of the water outlet valve 100 extends into the middle cavity of the upper coupler. In this way, the heating function of the container body 200 can be realized. Moreover, the lower part of the water outlet valve 100 extends into the middle cavity of the upper coupler, which is compact in structure and does not affect the power supply of the heating element 220.
