Description

Technical Field

[0001] The utility model relates to the field of water tanks, in particular to a water tank structure that prevents water from dripping. Background Art

[0002] As people's material living standards continue to improve and increase, the demand for water tanks in various types of equipment has become more and more diverse. Coffee machines, soybean milk machines, ice machines, instant hot water dispensers, fabric cleaning machines and other products have all derived product series with water tanks. Taking the patent document with patent application number CN201020514340.3 as an example, the water tank is independent of the water tank support (i.e., the water tank seat), but this type of water tank structure has a common problem in that there are always trace water droplets remaining at the water inlet at the bottom of the water tank. When the water tank is taken away from the water tank support, the sealing ring is not closed in time, resulting in a small amount of water droplets falling on the water tank support. Moreover, if the water tank is used as a sewage tank, the falling sewage will cause the water tank support to be contaminated, increasing the cleaning workload. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the utility model provides a drip-proof water tank structure, which solves the dripping problem.

[0004] The utility model is realized by the following technical solutions:

[0005] A water tank structure for preventing dripping, comprising:

[0006] A water tank body having a containing cavity for containing liquid;

[0007] The water tank seat body is provided with a supporting platform, and the supporting platform is used to support the water tank body;

[0008] A swing structure is pivotally connected to the water tank seat body through a pivot shaft; the swing structure comprises a pressure block and a driven member linked to the pressure block;

[0009] A water inlet connector, linked to the driven component;

[0010] Among them, when the water tank body is supported by the supporting platform, the pressure block of the swinging structure is pressed by the water tank body, and the water inlet connector extends into the accommodating cavity; when the water tank body is separated from the supporting platform, the swinging structure is in a natural state, and the water inlet connector is located outside the accommodating cavity.

[0011] The pressure block of the swing structure is pressed by the water tank body, so that the water inlet connector is linked to extend into the accommodating cavity, thereby ensuring that the water tank body and the water inlet connector are reliably matched; and, since the water inlet of the water inlet connector is located at the top of the water tank body, no water leakage will occur when the water tank body is lifted from the water tank seat. Moreover, when the water tank body is separated from the supporting platform, the swing structure is in a natural state, and the water inlet connector is located outside the accommodating cavity, that is, the water inlet connector will not interfere with the removal of the water tank body.

[0012] Furthermore, the pressure block and the driven member are located on two opposite horizontal sides of the pivot axis; when the water tank body is separated from the supporting platform, the swing structure is driven to return to a natural state under the gravity of the driven member. In this way, the swing structure is driven to return to a natural state by utilizing the weight imbalance on both sides of the swing structure.

[0013] Furthermore, the water inlet connector is connected to a water inlet pipe, and the water inlet pipe is located on a side of the driven component away from the accommodating cavity. In this way, the water inlet pipe not only serves as a water inlet, but also serves as a counterweight.

[0014] Furthermore, the water tank seat is provided with at least two supporting blocks, each of which is provided with an arc-shaped supporting groove; the pivot shaft is movably connected to a plurality of the arc-shaped supporting grooves. Thus, the structure of the anti-drip water tank structure is relatively simple and the assembly difficulty is relatively low.

[0015] Furthermore, the water tank seat has a cover, the cover has a first through hole; the cover has a plurality of arc-shaped undercut grooves, the plurality of arc-shaped undercut grooves are correspondingly engaged with one of the arc-shaped supporting grooves, and form a circular hole structure with the corresponding arc-shaped supporting groove; the supporting platform has a second through hole; the pressure block is correspondingly penetrated in the first through hole and the second through hole. In this way, the running stability of the pivot shaft is enhanced.

[0016] Furthermore, the circumferential angle of the arc-shaped supporting groove is greater than 180°, so that the top of the arc-shaped supporting groove forms a buckle; the pivot shaft is clamped in the arc-shaped supporting groove; the supporting platform is provided with a second through hole; and the pressure block is correspondingly provided in the second through hole. In this way, there is no need to set a cover, and the assembly method is simpler and more convenient.

[0017] Furthermore, the swing structure is provided with a plug hole, and the swing structure is also provided with a key slot connected to the plug hole; the pivot shaft is connected with a transmission key, the pivot shaft is plugged into the plug hole, and the transmission key is plugged into the key slot. In this way, the swing structure and the pivot shaft are fixed together in the circumferential direction.

[0018] Furthermore, the driven member is a plate-like structure, the driven member is provided with a third through hole, the driven member is also provided with a plurality of compensation grooves, the plurality of compensation grooves are distributed at intervals around the circumference of the third through hole, and are all connected to the third through hole; the water inlet connector is connected with a clamping ring, the clamping ring is located between the accommodating cavity and the driven member, and is limited by the driven member. In this way, the assembly convenience of the water inlet connector and the driven member is improved, and the connection between the two is ensured to be sufficiently stable.

[0019] Furthermore, the water tank body is provided with an avoidance hole, and the avoidance hole is used for the water inlet connector to be inserted into the accommodating cavity; the avoidance hole is a waist-shaped hole, and the length direction of the waist-shaped hole is the gravity direction; the width of the waist-shaped hole is smaller than the outer diameter of the clamp ring. In this way, the water inlet connector is protected.

[0020] Furthermore, the water tank seat has a protective shell, the protective shell has a protective cavity, and the driven component and the water inlet pipe are both located in the protective cavity. In this way, the swing structure is in a concealed position.

[0021] The beneficial effects of the anti-drip water tank structure of the utility model are as follows: the pressure block of the swing structure is pressed by the water tank body, so that the water inlet connector is linked to extend into the accommodating cavity, thereby ensuring that the water tank body and the water inlet connector are reliably matched; and, based on the water inlet of the water inlet connector being located at the top of the water tank body, no water leakage will occur when the water tank body is lifted from the water tank seat. Moreover, when the water tank body is separated from the supporting platform, the swing structure is in a natural state, and the water inlet connector is located outside the accommodating cavity, that is, the water inlet connector will not interfere with the removal of the water tank body.

DETAILED DESCRIPTION

[0029] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0030] First embodiment:

[0031] See also Figure 1-Figure 3 A drip-proof water tank structure includes: a water tank body 1, a water tank seat body 2, a swing structure 3, and a water inlet connector 5.

[0032] The water tank body 1 has a receiving chamber 11 for receiving liquid.

[0033] The water tank base body 2 is provided with a supporting platform 21 , and the supporting platform 21 is used to support the water tank body 1 .

[0034] The swing structure 3 is pivotally connected to the water tank seat 2 via a pivot shaft 4; the swing structure 3 includes a pressure block 31 and a driven member 32 linked to the pressure block 31. In this embodiment, the swing structure 3 is preferably a lever structure, but it should be noted that in the basic solution, it can also be a swing rod structure.

[0035] The water inlet connector 5 is linked to the driven member 32 . When the driven member 32 swings relative to the pivot shaft 4 , the swing structure 3 swings around the pivot shaft 4 .

[0036] Among them, when the water tank body 1 is supported by the supporting platform 21, the pressure block 31 of the swing structure 3 is pressed by the water tank body 1, and the water inlet connector 5 extends into the accommodating cavity 11; when the water tank body 1 is separated from the supporting platform 21, the swing structure 3 is in a natural state, and the water inlet connector 5 is located outside the accommodating cavity 11.

[0037] Specifically, when the water tank body 1 is placed on the support platform 21, under the pressure of the gravity of the water tank body 1, the pressure block 31 is pressed so that the driven member 32 swings toward the direction close to the water tank body 1, thereby linking the water inlet connector 5 to extend into the accommodating chamber 11. When the water tank body 1 is removed from the support platform 21, the pressure block 31 loses the pressure of the gravity of the water tank body 1, and the swing structure 3 returns to the natural state, that is, the water inlet connector 5 is located outside the accommodating chamber 11. Among them, in this embodiment, as a preferred structural mode for driving the swing structure 3 to return to the natural state, the pressure block 31 and the driven member 32 are located on the horizontal opposite sides of the pivot shaft 4; when the water tank body 1 is separated from the support platform 21, the swing structure 3 is driven to return to the natural state under the action of the gravity of the driven member 32. That is to say, the swing structure 3 at this time is a lever structure, and the imbalance of the weight on both sides of the swing structure 3 is used to drive the swing structure 3 to return to the natural state. Among them, as an alternative setting method, the swing structure 3 is based on the rocker principle, and one end of the rocker structure 3 is connected to a reset spring. The reset spring can be a compression spring or a tension spring, or a rubber pad, etc.

[0038] Obviously, the pressure block 31 of the swing structure 3 is pressed by the water tank body 1, so that the water inlet connector 5 is linked to extend into the accommodating chamber 11, thereby ensuring that the water tank body 1 and the water inlet connector 5 are reliably matched; and, based on the water inlet of the water inlet connector 5 being located at the top of the water tank body 1, no water leakage will occur when the water tank body 1 is lifted from the water tank seat 2. Moreover, based on the fact that the water tank body 1 is separated from the supporting platform 21, the swing structure 3 is in a natural state, and the water inlet connector 5 is located outside the accommodating chamber 11, that is, the water inlet connector 5 will not interfere with the removal of the water tank body 1.

[0039] In addition, it should be noted that a drip-proof water tank structure is particularly suitable for use as a waste water tank for a water purifier. Waste water dripping from the water inlet connector 5 is collected by the water tank body 1 and discharged uniformly without causing dripping, thereby avoiding unnecessary cleaning work. However, in actual use, a drip-proof water tank structure can also be used as a pure water tank.

[0040] In this embodiment, preferably, the water inlet connector 5 is connected to a water inlet pipe 6, and the water inlet pipe 6 is located on the side of the driven member 32 away from the accommodating chamber 11. In this way, the counterweight of the water inlet pipe 6 increases the single-sided weight of the swing structure 3, thereby more reliably ensuring that the swing structure 3 can be restored to a natural state by gravity. In this way, the water inlet pipe 6 not only serves as a water inlet, but also serves as a counterweight.

[0041] In this embodiment, in order to facilitate the installation of the pivot shaft 4, preferably, the water tank seat body 2 is provided with at least two supporting blocks 22, and the supporting blocks 22 are provided with arc-shaped supporting grooves 221; the pivot shaft 4 is movably overlapped with the plurality of arc-shaped supporting grooves 221. This arrangement makes the structure of a drip-proof water tank structure relatively simple and the assembly difficulty is relatively low. Moreover, the two supporting blocks 22 arranged at intervals can further save material costs. It can be understood that as an alternative arrangement, it can also be connected to the pivot shaft 4 through a casting hole.

[0042] In this embodiment, in order to enhance the running stability of the pivot shaft 4, preferably, the water tank seat body 2 has a cover 23, the cover 23 has a first through hole 231; the cover 23 has a plurality of arc-shaped undercut grooves 232, the plurality of arc-shaped undercut grooves 232 are correspondingly engaged with one of the arc-shaped supporting grooves 221, and form a circular hole structure with the corresponding arc-shaped supporting grooves 221; the supporting platform 21 is provided with a second through hole 24; the pressure block 31 is correspondingly penetrated in the first through hole 231 and the second through hole 24.

[0043] In this embodiment, in order to improve the assembly convenience of the water inlet connector 5 and the driven member 32, and to ensure that the connection between the two is sufficiently stable. Preferably, the driven member 32 is a plate-like structure, the driven member 32 is provided with a third through-hole 321, and the driven member 32 is also provided with a plurality of compensation grooves 322, the plurality of compensation grooves 322 are distributed at intervals around the circumference of the third through-hole 321, and are all connected to the third through-hole 321; the water inlet connector 5 is connected with a snap ring 51, the snap ring 51 is located between the accommodating chamber 11 and the driven member 32, and is limited by the driven member 32. In this way, the snap ring 51 of the water inlet connector 5 is located between the water tank body 1 and the driven member 32. It can be understood that, as an alternative setting, the water inlet connector 5 and the driven member 32 can be fixed together by bonding or screws, etc.

[0044] In this embodiment, in order to protect the water inlet connector 5, preferably, the water tank body 1 is provided with an avoidance hole 12, and the avoidance hole 12 is used for the water inlet connector 5 to be inserted into the accommodating cavity 11; the avoidance hole 12 is a waist-shaped hole, and the length direction of the waist-shaped hole is the gravity direction. More preferably, in order to prevent the water inlet connector 5 from swinging excessively and affecting the weight distribution of the swing structure 3, the width of the waist-shaped hole is smaller than the outer diameter of the clamp 51. In this way, it is better to ensure that the swing structure 3 returns to a natural state by its own weight.

[0045] In this embodiment, in order to make the swing structure 3 in a concealed position, preferably, the water tank seat body 2 has a protective shell 13, the protective shell 13 has a protective cavity 14, and the driven component 32 and the water inlet pipe 6 are both located in the protective cavity 14.

[0046] In this embodiment, the avoidance hole 12 is located above the highest water level mark.

[0047] Second embodiment:

[0048] See also Figure 4 The second embodiment of the utility model includes the first embodiment, and is different from the first embodiment in that: the water tank body 1 does not need to be provided with a avoidance hole 12, and the water inlet connector 5 is located above the absolute highest water level of the water tank body 1 (i.e., the top of the cylinder wall).

[0049] Third embodiment:

[0050] See also Figure 5 and Figure 6 The third embodiment of the utility model includes the first embodiment, and is different from the first embodiment in that: in this embodiment, preferably, the circumferential angle of the arc-shaped supporting groove 221 is greater than 180°, so that the top of the arc-shaped supporting groove 221 forms a buckle 222; the pivot shaft 4 is clamped in the arc-shaped supporting groove 221; the supporting platform 21 is provided with a second through hole 24; and the pressure block 31 is correspondingly penetrated in the second through hole 24. In this way, there is no need to set the cover 23, and the assembly method is simpler and more convenient.

[0051] In this embodiment, preferably, the swing structure 3 is provided with an insertion hole 33, and the swing structure 3 is also provided with a key slot 34 connected to the insertion hole 33; the pivot shaft 4 is connected with a transmission key 41, the pivot shaft 4 is inserted into the insertion hole 33, and the transmission key 41 is inserted into the key slot 34. In this way, the swing structure 3 and the pivot shaft 4 are fixed together in the circumferential direction. As an alternative, the swing structure 3 and the pivot shaft 4 can be formed by integral casting, so that assembly is not required.

[0052] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
