Abstract

This application relates to a water tank structure and a water purifier. The water tank structure includes: a mounting base and a water tank inner liner. The outer wall of the water tank inner liner is provided with a limiting groove. The water tank structure also includes: a rebound mechanism located between the inner side wall of the mounting base and the outer side wall of the water tank inner liner, with the fixed end of the rebound mechanism connected to the mounting base; a limiting mechanism including a drive module and a first limiting member. The drive module is mounted on the mounting base and is drivenly connected to the first limiting member. After the water tank inner liner is inserted into the mounting base, the first limiting member moves into the limiting groove to block the water tank inner liner, causing the water tank inner liner to compress the rebound mechanism.

The water tank structure can be used in a water purifier, allowing the water tank inner liner to pop out quickly after water is dispensed, thus effectively improving the convenience of water dispensing.

Description

Technical Field

[0001] This application relates to the field of water purification equipment technology, and in particular to water tank structure and water purifier. Background Technology

[0002] Water purifiers can purify, dispense, and heat water to meet the convenient and safe drinking water needs of families. Users typically only need to obtain water directly from the dispenser's spout.

[0003] In related technologies, some water purifiers are equipped with a water tank for storing purified water to improve the convenience of water dispensing. However, because the water tank and the water outlet of the water purifier are connected by a structure, it is necessary to manually insert or remove the water tank with considerable force to connect or disconnect the water tank from the water outlet of the water purifier when dispensing water, which makes the water dispensing operation inconvenient. Utility Model Content

[0004] The first technical problem solved by this utility model is to provide a water tank structure that allows direct removal of the inner tank for water use, making it convenient to use.

[0005] The second technical problem solved by this utility model is to provide a water purifier that can effectively improve the convenience of water access.

[0006] The first technical problem mentioned above is solved by the following technical solution: a water tank structure, including a mounting base and a water tank liner, wherein the outer wall of the water tank liner is provided with a limiting groove, and the water tank structure further includes: a rebound mechanism, wherein the rebound mechanism is located between the inner side wall of the mounting base and the outer side wall of the water tank liner, and the fixed end of the rebound mechanism is connected to the mounting base; a limiting mechanism, wherein the limiting mechanism includes a drive module and a first limiting member, the drive module is disposed on the mounting base, and the drive module is drivenly connected to the first limiting member; after the water tank liner is inserted into the mounting base, the first limiting member moves into the limiting groove to block the water tank liner, causing the water tank liner to compress the rebound mechanism; the drive module is configured to drive the first limiting member away from the limiting groove to release the obstruction, causing the rebound mechanism to rebound the water tank liner.

[0007] The water tank structure of this utility model offers the following advantages compared to the prior art: When water needs to be dispensed, the inner tank is inserted into the mounting base. At this time, the first limiting member of the limiting mechanism engages with the limiting slot of the inner tank to limit its position, facilitating water dispensing. Simultaneously, the rebound mechanism is in a compressed state. After the inner tank is filled with water, the driving module of the limiting mechanism drives the first limiting member to leave the limiting slot, releasing the restriction on the inner tank. The rebound mechanism then switches to the pop-out state, automatically ejecting the inner tank for the user to remove. Therefore, the water tank structure of this utility model can be used in water purifiers, allowing the inner tank to pop out quickly after water dispensing, effectively improving water dispensing convenience.

[0008] In one embodiment, the first limiting member includes a force-receiving end, a rotating end, and a limiting end. The rotating end is located between the force-receiving end and the limiting end. The rotating end is rotatably disposed on the mounting base. The driving module is configured to drive the force-receiving end to rotate the first limiting member.

[0009] In one embodiment, the limiting end extends downward to form a limiting head, which engages with the limiting slot for limiting.

[0010] In one embodiment, the front end of the limiting card head is provided with an inclined surface that slopes downwards and backwards.

[0011] In one embodiment, when the first limiting member moves into the limiting slot, the limiting end is horizontally positioned, the force-receiving end is inclined, and the included angle between the limiting end and the force-receiving end is an obtuse angle.

[0012] In one embodiment, the drive module includes a first movable member that can move relative to the mounting base in a front-back direction, one end of the first movable member having a mounting port, and the force-bearing end passing through the mounting port.

[0013] In one embodiment, the driver module further includes:

[0014] The mounting base is provided on the mounting base. The mounting base is hollow and has a first limiting wall and a second limiting wall along the front-back direction. The other end of the first movable member away from the mounting opening has a first limiting protrusion. The first movable member passes through the mounting base and the first limiting protrusion is located between the first limiting wall and the second limiting wall.

[0015] A first elastic member is located inside the mounting base, one end of which abuts against the first limiting protrusion and the other end of which abuts against the second limiting wall. The first elastic member is configured to apply a forward elastic force to the first movable member.

[0016] In one embodiment, the driver module further includes:

[0017] A second movable member passes through the first movable member in the vertical direction, and one end of the second movable member is provided with a second limiting protrusion;

[0018] The second elastic member has one end abutting against the second limiting protrusion and the other end abutting against the bottom wall of the first movable member;

[0019] The second elastic member is configured to apply a downward elastic force to the second movable member so that the second movable member abuts against the limiting end.

[0020] In one embodiment, the rebound mechanism includes a movable push rod, a push rod front pad, and a third elastic element. The push rod front pad is connected to the movable push rod and protrudes radially from the movable push rod. The third elastic element is sleeved outside the movable push rod, with one end connected to the mounting base and the other end abutting against the push rod front pad.

[0021] The second technical problem mentioned above is solved by the following technical solution: a water purifier, wherein the water purifier includes the water tank structure described in any of the above-mentioned items.

[0022] The water purifier described in this utility model has the following advantages compared with the prior art: The water purifier adopts a water tank structure. Based on the structural design of the water tank structure, the inner tank can be quickly popped out, making it convenient to take out water. This allows the water purifier to prepare water in advance during off-peak hours, so that users do not need to wait when they need water and can directly take out the inner tank to use the water, making it convenient to use.

Detailed Implementation

[0042] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0043] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0044] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0045] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0047] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0048] See Figure 1 and Figure 2 The diagram shows a schematic representation of a water purifier 1 according to an embodiment of this application. The water purifier 1 provided in this embodiment includes a water tank structure 10. Specifically, see [reference needed]. Figures 3 to 6 As shown, the water tank structure 10 includes a mounting base 100, a water tank inner liner 300, a rebound mechanism 400, and a limiting mechanism 500. It should be noted that in the descriptions of directions in this document, "rearward" or "rear" refers to the direction in which the water tank inner liner 300 inserts into the mounting base 100; "forward" or "front" refers to the direction in which the water tank inner liner 300 detaches from the mounting base 100; "upward" or "above" refers to the direction towards the top of the water purifier 1; and "downward" or "below" refers to the direction towards the bottom of the water purifier 1.

[0049] The mounting base 100 is used to support the rebound mechanism 400 and other components. For example, the mounting base 100 can be configured as a hollow frame structure with an internal mounting groove 120 for accommodating the water tank liner 300. Furthermore, the water purifier 1 can be an embedded integrated water purifier, and the mounting base 100 can be connected to the housing of the water purifier 1 or be configured as part of the housing of the water purifier 1.

[0050] The inner tank liner 300 has an internal cavity for holding water, and the outer wall of the inner tank liner 300 is provided with a limiting groove 313. When the inner tank liner 300 is pushed backward, the inner tank liner 300 is inserted into the mounting groove 120 of the mounting base 100 to receive water.

[0051] The rebound mechanism 400 is located between the inner wall of the mounting base 100 and the outer wall of the water tank liner 300, and its fixed end is connected to the mounting base 100. Exemplarily, the rebound mechanism 400 is connected to the mounting base 100 and disposed at the bottom of the mounting groove 120, and is used in conjunction with the limiting mechanism 500. Specifically, when the water tank liner 300 is inserted into the bottom of the mounting groove 120, the rebound mechanism 400 is compressed by the water tank liner 300. At this time, the rebound mechanism 400 has a tendency to push the water tank liner 300 forward, i.e., the rebound mechanism 400 is in a compressed state. To prevent the rebound mechanism 400 from rebounding the water tank liner 300, the limiting mechanism 500 can be used to limit the water tank liner 300.

[0052] See Figure 4 As shown, the limiting mechanism 500 includes a drive module 510 and a first limiting member 520. The drive module 510 is disposed on the top of the mounting base 100, and the drive module 510 is drivenly connected to the first limiting member 520. When the water tank inner liner 300 is inserted into the mounting groove 120 of the mounting base 100, the drive module 510 drives the first limiting member 520 to move towards the mounting groove 120 until the first limiting member 520 moves into the limiting slot 313 to block the water tank inner liner 300, causing the water tank inner liner 300 to compress the rebound mechanism 400. At this time, the rebound mechanism 400 is in a compressed state. After the water is filled, the drive module 510 drives the first limiting member 520 to leave the limiting slot 313 to release the obstruction on the inner tank 300. At this time, the rebound mechanism 400 switches from the compressed state to the pop-out state, that is, the rebound mechanism 400 can rebound the inner tank 300, so that the inner tank 300 moves forward to disengage from the mounting slot 120 of the mounting base 100.

[0053] With the above structural design, when a user needs to take water, the inner tank liner 300 is pushed backward to insert into the mounting groove 120 of the mounting base 100. At this time, the inner tank liner 300 is limited by the limiting mechanism 500, while the rebound mechanism 400 is in a compressed state. After the inner tank liner 300 is filled with water, the limiting mechanism 500 releases the limitation on the inner tank liner 300. At this time, the rebound mechanism 400 switches to the pop-out state, and the inner tank liner 300 can be automatically popped out so that the user can take out the inner tank liner 300 from the mounting groove 120. Thus, the water tank structure 10 of this embodiment can not only ensure a stable connection between the inner tank liner 300 and the mounting base 100 for water taking, but also quickly pop out the inner tank liner 300 for user water use. This water tank structure 10 can be used in a water purifier 1, allowing the water purifier 1 to prepare water in advance during idle periods, so that users do not need to wait and can directly take out the inner tank liner 300 to use water, making it convenient to use.

[0054] Further, see Figure 5 , Figure 8 , Figure 9and Figure 11 , Figure 12 As shown, the first limiting member 520 includes a force-receiving end 521, a rotating end 522, and a limiting end 523, which are sequentially connected to form a strip-shaped structure. Specifically, the force-receiving end 521 is connected to the drive module 510, and the rotating end 522 is connected between the force-receiving end 521 and the limiting end 523. The rotating end 522 is rotatably mounted on the mounting base 100. The drive module 510 is configured to drive the force-receiving end 521 to rotate the first limiting member 520. When the drive module 510 drives the force-receiving end 521 to move backward and causes the rotating end 522 to rotate, thereby moving the limiting end 523 away from the inner tank liner 300, the limiting of the inner tank liner 300 is released. When the drive module 510 drives the force-receiving end 521 forward, the force-receiving end 521 and the rotating end 522 drive the limiting end 523 to approach the inner tank 300, thereby limiting the inner tank 300. The rotational setting of the first limiting member 520 allows the limiting end 523 to rotate flexibly to block or release the inner tank 300, which can improve the flexibility and reliability of the first limiting member 520 and ensure that the limiting and releasing of the inner tank 300 can be accurately achieved under the drive of the drive module 510.

[0055] Optionally, the limiting end 523 extends downward to form a limiting head 5231, which engages with the limiting slot 313 for limiting. For example, see [reference needed]. Figure 8 and Figure 11 As shown, the end of the limiting end 523 furthest from the rotating end 522 is provided with a limiting head 5231. The limiting head 5231 extends downward and protrudes from the side wall of the limiting end 523, and connects with the limiting end 523 to form a hook-like structure. (See reference...) Figure 9 As shown, when the first limiting member 520 moves into the limiting slot 313, the limiting end 523 is horizontally positioned to fit against the outer wall of the water tank inner liner 300. Furthermore, the force-receiving end 521 is inclined, and the angle between the limiting end 523 and the force-receiving end 521 is obtuse. Therefore, when the limiting end 523 moves towards the water tank inner liner 300 until the limiting head 5231 engages with the limiting slot 313, the hook-like structure formed by the connection between the limiting head 5231 and the limiting end 523 firmly hooks onto the side wall of the limiting slot 313, effectively blocking the water tank inner liner 300 and preventing it from loosening or falling off during water intake, thus ensuring the stability of the water intake process. When the drive module 510 drives the force-receiving end 521 away from the inner tank 300, the limit card head 5231 disengages from the limit card slot 313, thereby releasing the limit on the inner tank 300 so that the inner tank 300 can be removed.

[0056] Further, see Figure 12As shown, the front end of the limiting head 5231 has an inclined surface 5232 that slopes downwards and backwards. Therefore, when the water tank inner liner 300 is pushed backwards into the mounting base 100, the water tank inner liner 300 first contacts the inclined surface 5232 of the limiting head 5231 and presses against the limiting head 5231, allowing the limiting head 5231 to move upwards for insertion into the water tank inner liner 300. Alternatively, when the water tank inner liner 300 needs to be inserted, the limiting head 5231 can be directly driven upwards via the drive module 510, allowing the water tank inner liner 300 to be inserted into the mounting base 100 without obstruction.

[0057] In some embodiments, see Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the drive module 510 includes a first movable member 512 that can move relative to the mounting base 100 in the front-back direction. One end of the first movable member 512 is provided with a mounting port 5121, and the force-receiving end 521 is disposed through the mounting port 5121. Thus, when the first movable member 512 moves in the front-back direction, the first movable member 512 can drive the force-receiving end 521 to move back and forth, thereby driving the limiting end 523 and the limiting clip 5231 to move, so that the limiting clip 5231 can be inserted into or disengaged from the limiting clip slot 313, thereby realizing the function of limiting or releasing the inner tank liner 300.

[0058] Furthermore, the drive module 510 also includes a mounting base 511 and a first elastic member 513. See, for example, [reference needed]. Figure 4 , Figures 7 to 12As shown, the mounting base 511 can be a split or integrated structure. The mounting base 511 is mounted on the mounting base 100 and is hollow. The mounting base 511 has a first limiting wall 5111 and a second limiting wall 5112 along the front-rear direction. The first movable member 512 has a first limiting protrusion 5122 at its end away from the mounting opening 5121. The first movable member 512 passes through the mounting base 511, and the first limiting protrusion 5122 is located between the first limiting wall 5111 and the second limiting wall 5112. A first elastic member 513 is disposed within the mounting base 511. One end of the first elastic member 513 abuts against the first limiting protrusion 5122, and the other end abuts against the second limiting wall 5112. The first elastic member 513 is configured to apply a forward elastic force to the first movable member 512. For example, the first elastic member 513 can be a spring, and it is sleeved on the outside of the first movable member 512. The first elastic element 513 applies a spring force to the first movable element 512, causing the first movable element 512 to move forward, thereby driving the first limiting element 520 to move and block the water tank inner liner 300. The first movable element 512 acts as a "button." When the user presses the first movable element 512, it overcomes the spring force of the first elastic element 513, driving the first limiting element 520 to release the blockage. When the user releases the first movable element 512, it resets under the action of the first elastic element 513, and drives the first limiting element 520 to reset as well. Thus, through the cooperation of the first elastic element 513 and the first movable element 512, the limiting mechanism 500 can reliably block or release the water tank inner liner 300, ensuring that the water tank inner liner 300 is stably fixed when water is taken out, and that the limiting can be easily released by external force after water is taken out, realizing the automatic pop-out of the water tank inner liner 300, which is convenient to operate.

[0059] Furthermore, the drive module 510 also includes a second movable element 514 and a second elastic element 515. See further... Figure 4 , Figures 7 to 12As shown, the second movable member 514 passes through the first movable member 512 in a vertical direction, and one end of the second movable member 514 is provided with a second limiting protrusion 5141. One end of the second elastic member 515 abuts against the second limiting protrusion 5141, and the other end abuts against the bottom wall of the first movable member 512; the second elastic member 515 is configured to apply a downward elastic force to the second movable member 514 so that the second movable member 514 abuts against the limiting end 523. Specifically, the second movable member 514 and the second elastic member 515 are located on the side of the limiting end 523 away from the inner liner 300 of the water tank. The second movable member 514 is configured as a long strip structure, which passes through the first movable member 512 and can move relative to the first movable member 512. The second elastic element 515 can be a spring. The second elastic element 515 is sleeved outside the second movable element 514. One end of the second elastic element 515 abuts against the outer wall of the first movable element 512, and the other end abuts against the second limiting protrusion 5141 at the bottom of the second movable element 514. When the second elastic element 515 is in a compressed state, it applies a downward elastic force to the second movable element 514, causing the second movable element 514 to move towards the limiting end 523 and abut against it, thereby pushing the limiting end 523 and the limiting latch 5231 into tight contact with the inner tank 300. This further enhances the stability and reliability of the limiting mechanism 500, ensuring that the limiting end 523 remains stable when blocking the inner tank 300, preventing loosening due to external interference, and allowing for smooth reset when the blockage is released.

[0060] In some embodiments, the rebound mechanism 400 includes a fixed end, a movable push rod 410, a push rod front pad 420, and a third elastic element 430, with the fixed end connected to the mounting base 100. For example, see [reference needed]. Figure 4 , Figure 7 and Figure 10 As shown, the rebound mechanism 400 includes two movable push rods 410, which are respectively mounted on the fixed ends of the mounting base 100. A push rod front pad 420 is connected to the ends of the two movable push rods 410, and the push rod front pad 420 protrudes radially from the movable push rods 410. The rebound mechanism 400 also includes two third elastic elements 430, which can be springs. The third elastic elements 430 are sleeved around the movable push rods 410, with one end connected to the mounting base 100 and the other end abutting against the push rod front pad 420. The third elastic elements 430 apply a spring force to the movable push rods 410, causing them to move towards the inner tank liner 300 and abut against it, thereby driving the inner tank liner 300 forward to separate it from the mounting base 100. Of course, the number of movable push rods 410 and third elastic members 430 is not limited to two. In other optional embodiments, the number of movable push rods 410 and third elastic members 430 can be one, three, four, etc.

[0061] Specifically, see Figures 7 to 9 As shown, when the user pushes the water tank inner liner 300 backward, the water tank inner liner 300 abuts against the push rod front pad 420 and compresses the third elastic element 430. At this time, the rebound mechanism 400 is in a compressed state. The first elastic element 513 of the limiting mechanism 500 applies force to make the limiting head 5231 engage with the limiting groove 313 of the water tank inner liner 300. At the same time, the second elastic element 515 applies force to further improve the firmness of the engagement between the limiting head 5231 and the limiting groove 313, thereby blocking and limiting the water tank inner liner 300 through the limiting mechanism 500. (See reference...) Figures 10 to 12 As shown, when the user presses the first movable part 512 to disengage the limiting card head 5231 from the limiting card slot 313, the limiting mechanism 500 is released from obstruction, and the rebound mechanism 400 is in the pop-out state. The third elastic element 430 is released and pushes the water tank inner liner 300 through the push rod front pad 420 and the movable push rod 410, realizing the automatic pop-out function of the water tank inner liner 300 and improving the convenience of water dispensing.

[0062] See Figure 6 As shown, in some embodiments, the water tank liner 300 includes a housing 310, the interior of which forms a cavity for holding water. Furthermore, considering the cleaning of the water tank liner 300, this embodiment sets the housing 310 of the water tank liner 300 as a split structure. The housing liner 310 includes a main body 310a and a cover 310b, the cover 310b being threadedly connected to the main body 310a, and the outer wall of the housing liner 310 having a limiting groove 313. When cleaning is required, the main body 310a and the cover 310b can be disassembled to flush the inside of the water tank liner 300.

[0063] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0064] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
