Referring to fig. 1 to 6, an embodiment of the present invention provides a water pumping assembly 100 mounted on a water bucket 800, including: the water pumping cover 200 comprises a side coaming 210 and a top plate 220, the coaming 210 and the top plate 220 jointly enclose to form an accommodating cavity 230 with an opening, a bucket opening (not shown) of the water bucket 800 is embedded in the accommodating cavity 230, and the top plate 220 is provided with at least one through hole 221; a plurality of annular elastic sealing ribs 222 are arranged in the through hole 221, and the elastic sealing ribs 222 are arranged at intervals along the extending direction of the through hole 221; the tube 300 is slidably mounted on the top plate 220 through the through hole 221, at least a portion of the tube 300 extends into the water bucket 800, and the tube 300 is in interference fit with the elastic sealing ribs 222.

It should be noted that the water tank in the market generally includes two sizes of 5 gallon and 3 gallon water tanks 800. The bucket 800 comprises a neck section 810 and a barrel section 820 which are sequentially communicated, the neck section 810 and the barrel section 820 are also generally cylindrical, and the diameter of the neck section 810 is smaller than that of the barrel section 820. The bucket opening is formed at one end of the bucket neck section 810 far away from the bucket body section 820, and the bucket opening is also the only water outlet of the bucket 800; the 5 gallon and 3 gallon bucket 800 differ in the height of the barrel section 820.

The water pumping cover 200 is sleeved on the water barrel 800, and the top plate 220 is provided with the through hole 221, so that the pipe body 300 can extend into the water barrel 800 through the through hole 221, and a user can pump water conveniently. In addition, a plurality of elastic sealing ribs 222 are arranged in the through hole 221 at intervals, and the tube body 300 and the elastic sealing ribs 222 are in interference fit; that is, when the tube 300 is inserted through the through hole 221, the elastic sealing ribs 222 are tightly attached to the sidewall of the tube 300, which forms a multi-layer sealed cavity. On one hand, external impurities are prevented from entering the water bucket 800 through the through hole 221, the surface of the pipe body 300 is smooth, impurities are not easy to retain, and the water quality in the water bucket 800 is improved; on the other hand, the multi-layer sealed cavity formed by the plurality of elastic sealing ribs 222 and the tube body 300 reduces the sliding resistance of the tube body 300 in the through hole 221 on the basis of meeting the sealing level of the side wall of the tube body 300, so that a user can flexibly adjust the length of the tube body 300 extending into the water barrel 800 as required, and the universality of the water pumping assembly 100 is improved.

Specifically, the tube 300 is a "Z" shaped tube.

It can be understood that, in order to improve the structural strength of the water bucket 800 itself, the bottom surface of the water bucket 800 is generally configured to be convex toward the bucket opening, and the height of the bottom surface is the highest at the center of the circle and the height of the edge far away from the center of the bottom surface is the lowest.

When the Z-shaped pipe extends into the bucket 800, the end of the Z-shaped pipe far away from the bucket opening is arranged at the edge of the bucket 800 far away from the circle center, the height of the Z-shaped pipe is the lowest, the water pumping component 100 can be ensured to pump the water at the lowest position in the bucket 800, and the water pumping efficiency of the water pumping component 100 is improved.

Preferably, the water pumping cover 200 and the elastic limiting rib 211 are made of rubber, so that the water pumping cover 200 can be stably sleeved on the water barrel 800, and the sealing performance between the elastic limiting rib 211 and the pipe body 300 is ensured.

Specifically, one end of the pipe 300 located outside the water bucket 800 may be connected to a water pump through a rubber hose, so as to pump water out of the water bucket 800.

Referring to fig. 2, 6 to 9, in some embodiments, a plurality of anti-receding portions 310 are disposed on an outer wall surface of the tube 300, and when the anti-receding portions 310 are located between the two elastic sealing ribs 222, the tube 300 can only slide in one direction in the through hole 221.

It will be appreciated that the two resilient sealing ribs 222 define a cavity therebetween, i.e., a sealed cavity. The anti-back part 310 is embedded in the sealed cavity, and the anti-back part 310 can only slide in one direction in the sealed cavity; on the one hand, the installation stability of the pipe body 300 in the through hole 221 is improved, on the other hand, impurities on two sides of the through hole 221 are prevented from being brought into the water bucket 800 or the sealed cavity when the pipe body 300 slides back and forth, and the water quality in the water bucket 800 is improved.

Preferably, the tube 300 can only slide within the through hole 221 in a direction away from the bung. That is, the pipe body 300 can only slide to reduce the length of the pipe body extending into the water tub 800, thereby preventing foreign substances in the external space from being brought into the water tub 800.

In some embodiments, the anti-backoff portion 310 comprises a lead-in ramp 311 and a stop surface 312; the stop surface 312 is perpendicular to the extending direction of the through hole 221, and the guide inclined surface 311 and the stop surface 312 are disposed at an included angle.

It should be noted that the extending direction of the through hole 221 is the extending direction of the central axes of the neck section 810 and the barrel section 820. And the sectional shape of the receding prevention portion 310 is triangular.

Since the stop surface 312 is perpendicular to the extending direction of the through hole 221, when the anti-receding portion 310 is embedded in the sealed cavity, the tube 300 can press the elastic limiting rib 211 along the guiding inclined surface 311, and the tube 300 can slide towards the inclined direction of the guiding inclined surface 311. When the guiding inclined surface 311 slides completely into the sealed cavity along the elastic limiting rib 211, the stop surface 312 also synchronously enters the sealed cavity. Since the stop surface 312 is substantially parallel or completely parallel to the surface of the elastic limit rib 211, the elastic fiber rib passing through the guide inclined surface 311 moves through the stop surface 312, that is, the retreat prevention portion 310 cannot or is difficult to retreat, so that the pipe body 300 can only smoothly slide toward one direction, but cannot slide and retreat toward the opposite direction.

Specifically, the included angle between the guide inclined surface 311 and the stop surface 312 is 30 ° to 60 °.

Further, in other embodiments, the included angle between the guiding inclined surface 311 and the stopping surface 312 may also be 25 °, or 45 °, or 75 °, etc., which is not limited herein.

Further, the cross-sectional shape of the recession prevention part 310 may be a trapezoid, a hemisphere, or the like, and is not limited herein.

Optionally, the anti-receding portion 310 is disposed around the tube body 300.

In some embodiments, the outer wall of the tube 300 is provided with a plurality of positioning grooves 350, and the plurality of positioning grooves 350 are spaced along the extending direction of the tube 300.

By providing the positioning groove 350 on the outer wall surface of the tube 300, when the tube 300 slides in the through hole 221 and the elastic sealing rib 222 is embedded into the positioning groove 350, it is possible to prompt the user that the tube 300 is installed in place.

Further, two sets of positioning grooves 350 are formed on the outer wall surface of the tube 300, and each set of positioning grooves 350 has two positioning grooves 350.

On one hand, the buckets 800 in the market have two specifications of 3 gallons and 5 gallons, and the two groups of positioning grooves 350 are arranged on the pipe body 300 and respectively correspond to the buckets 800 with the depths of the two specifications, so that the universality of the pipe body 300 can be improved; on the other hand, because the locating groove 350 is sunken towards the centre of a circle of the pipe body 300, only two locating grooves 350 are arranged in each group, so that the situation that all the elastic sealing ribs 222 are embedded in the locating grooves 350 can be avoided, the number of gaps formed between the elastic sealing ribs 222 and the locating grooves 350 is reduced, and the sealing performance of the water pumping assembly 100 is improved.

Further, in other embodiments, the number of positioning slots 350 in each group may also be 1, 3, etc., and is not limited herein.

In some embodiments, a side of the elastic sealing rib 222 away from the inner wall of the through hole 221 is provided with a guide arc 223.

It can be appreciated that, since the tube 300 is slidably mounted in the tube 300, the sliding resistance of the tube 300 in the tube 300 needs to be reduced to improve the efficiency of installing the water pumping assembly 100 for users.

Through set up the guide cambered surface 223 on the spacing muscle 211 of elasticity, when the body 300 pegged graft and gets into in the through-hole 221, the body 300 can improve the accuracy that body 300 inserted through-hole 221 through the guide effect of guide cambered surface 223, has improved the installation effectiveness of body 300.

Preferably, the cross-sectional shape of the elastic sealing rib 222 is a hemisphere.

Thus, the installation stability of the elastic sealing rib 222 on the inner side wall of the through hole 221 can be ensured, the surface shape of the elastic sealing rib 222 can be simplified, and the installation efficiency of the pipe body 300 can be improved.

Further, in other embodiments, the cross-sectional shape of the elastic sealing rib 222 may also be rectangular, triangular, etc., and is not limited herein.

Referring to fig. 3, in some embodiments, a plurality of limiting ribs 211 are disposed on the inner sidewall of the side wall plate 210 at intervals, and the limiting ribs 211 extend toward the extending direction of the through hole 221; when the water pumping cover 200 is sleeved on the water barrel 800, an air inlet channel 212 is formed between any two adjacent limiting ribs 211.

It should be noted that, since the water tub 800 is cylindrical and has a thick wall, the surface deformation of the water tub 800 is small when the water tub 800 is pressed, which can ensure the structural strength of the water tub 800 itself. However, when the water pumping assembly 100 pumps out the water in the water tank 800, if the water tank 800 is not filled with the air in time to fill the volume of the water pumped out by the water tank 800, the water tank 800 with a small deformation cannot maintain the water pumping assembly 100 to pump out more water.

Through the air inlet passage 212 formed on the inner side wall of the side wall plate 210, when the water in the water bucket 800 is pumped out by the water pumping assembly 100, the air in the external space enters the water bucket 800 through the air inlet passage 212, which can ensure that the pressure in the water bucket 800 is the same as or similar to the external space, and ensure the continuous stability of the water pumping assembly 100 for pumping out the water from the water bucket 800.

In some embodiments, the tubular body 300 is a metal tube.

The pipe body 300 made of metal has high structural strength, and the surface of the metal pipe is smooth. It can prolong the life of the pipe body 300 and facilitate the installation of the pipe body 300, improving the installation efficiency of the pipe body 300. In addition, the metal pipe is convenient to clean, bacteria are not easy to breed on the surface of the metal pipe, the cleanliness of the water pumping assembly 100 is improved, and the water quality is improved.

Further, in other embodiments, the material of the tube 300 may also be a hard material such as plastic or glass, which is not limited herein.

Referring to fig. 2, 6 to 10, in some embodiments, an anti-blocking joint 330 is installed at one end of the pipe 300 extending into the water bucket 800; and/or the other end of the pipe body 300 located outside the water tub 800 is formed with a mounting groove 340, and the mounting groove 340 is circumferentially disposed on the outer sidewall of the pipe body 300.

By installing the anti-blocking joint 330 on the pipe body 300, impurities in the water tub 800 can be prevented from blocking the pipe body 300, and the stability of the water pumping assembly 100 in use is improved.

In addition, an annular mounting groove 340 is formed on the outer side wall of the tube 300, so that a rubber hose and the like can be quickly connected to the tube 300, and the water pumping assembly 100 can be conveniently expanded and mounted.

Referring to fig. 11 to 12, in some embodiments, two through holes 221 are formed in the top plate 220, and a detachable dust plug 320 is embedded in at least one of the through holes 221.

Two through holes 221 are formed in the top plate 220, and a dust plug 320 is installed in at least one through hole 221. When the elastic limiting rib 211 in one through hole 221 fails and the sealing performance of the pipe body 300 cannot be guaranteed, the pipe body 300 can be quickly installed in the other through hole 221, so that the service life of the water pumping assembly 100 is prolonged; and the dust plug 320 can effectively seal the unused through hole 221, and the tightness of the water pumping assembly 100 is improved.

In addition, particularly, the water pumping cover 200 with two through holes 221 can install the pipe 300 in the two through holes 221 for pumping water, so that the water pumping efficiency of the water pumping assembly 100 is improved.

Further, in other embodiments, three through holes 221, four through holes 221, etc. are provided on the top plate 220, which is not limited herein.

In some embodiments, one of the through holes 221 of the top plate 220 is used for mounting the tube 300, and the other through hole 221 is used for mounting the water level measuring module 500; the water return module 600 comprises a three-way pipe 610, an overflow valve 620, a water pump 630 and a filter 640, two ends of the overflow valve 620 are respectively communicated with the through hole 221 without the pipe body 300 and the three-way pipe 610, two residual pipe openings of the three-way pipe 610 are respectively communicated with a water outlet of the water pump 630 and the filter 640, and a water inlet of the water pump 630 is communicated with the pipe body 300; and/or a sterilization module (not shown).

Through add water level measurement module 500 for pumping assembly 100, can accurate real-time feedback cask 800 interior water level, user experience is better.

Preferably, the water level measuring module 500 is an electrode probe having a detection capability of a plurality of water level heights.

By adding the water returning module 600 to the water pumping assembly 100, when the water pump 630 is started, water in the water bucket 800 can be pumped out through the pipe 300. When the filter element in the filter 640 is blocked or not unsealed due to long-term use, water cannot flow through the filter element, and the water pumped by the water pump 630 flows to the overflow valve 620; if water pump 630 goes out the increase of water pressure and exceeds the threshold value of overflow valve 620 for overflow valve 620 switches on, and then water backward flow and reentrant cask 800 are with the pressure release, namely water from return module 600 transportation return cask 800 in. The pressure between the water pump 630 and the filter 640 can be prevented from being continuously increased, so that the pipeline is prevented from falling off or the water pump 630 is prevented from being damaged, and the use safety of the water pumping assembly 100 is improved; in addition, particularly, if the water return module 600 returns water, the user can be reminded to replace or check the filter element.

By adding a sterilization module to the pumping assembly 100, the water quality in the water tub 800 can be improved.
