Description

Technical Field

[0001] The invention relates to the technical field of barrel cleaning machines, in particular to drinking water barrel cleaning equipment. Background Art

[0002] With the improvement of awareness of drinking water quality, residents are paying more and more attention to the safety of drinking water. Since tap water may have impurities, residual chlorine or secondary contamination of pipelines, and the bottled water market is counterfeit and substandard, many communities are currently equipped with water vending machines or direct drinking water machines to provide residents with convenient drinking water purchase services, so that residents can get purified drinking water more assured. Since water vending machines do not provide disposable containers, users need to prepare clean buckets or bottles in advance to directly receive purified drinking water. If residents' drinking water barrels are exposed to direct sunlight for a long time, even pure water will promote the growth of microalgae and form moss on the inner wall of the drinking water barrel. Therefore, in order to clean the drinking water barrels, the community generally installs a barrel brush machine near the water vending machine to facilitate residents to clean the drinking water barrels.

[0003] As in the prior art, the patent with the patent authorization announcement number CN215032074U discloses a barrel-lifting and barrel-brushing machine for producing bottled drinking water, including an equipment device, a cleaning chamber is provided inside the equipment device, a cleaning brush is provided inside the cleaning chamber, a clamping device is provided at the bottom end of the cleaning chamber, and the clamping device includes a telescopic rod, a fixing ring, a connecting rod, a first fixing plate, a foam pad and a fixing hole.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figures 1 to 12A drinking water bucket cleaning device comprises a bucket brush machine body 1 and an inner brush roller 2 and an outer brush roller 3 installed inside the bucket brush machine body 1. A cylinder 7 is fixedly connected to one side of the bucket brush machine body 1, a top cover 8 is fixedly connected to the output end of the cylinder 7, a round plate 9 is connected to the middle position of the top cover 8, a fixed clamping rod 20 is rotatably connected to the end of the bottom of the round plate 9 close to the control button of the bucket brush machine body 1, a bottom plate 21 is provided at the bottom of the fixed clamping rod 20, the fixed clamping rod 20 is rotatably connected to the bottom plate 21, and symmetrical upper slide grooves 15 are opened on both sides of the bottom of the round plate 9 away from one end of the fixed clamping rod 20, an upper positioning rod 16 is fixedly connected to the inside of the upper slide groove 15, and an end of the upper positioning rod 16 close to the inner brush roller 2 is sleeved with An upper slider 17 is slidably connected to the upper slide groove 15, and a movable clamping rod 19 is rotatably connected to the bottom of the upper slider 17. An upper elastic member 18 is sleeved on the end of the upper positioning rod 16 away from the inner brush roller 2. Lower slide grooves 22 matching the upper slide groove 15 are opened on both sides of the bottom plate 21 away from the end of the fixed clamping rod 20. A lower positioning rod 23 is fixedly connected to the inside of the lower slide groove 22. The end of the lower positioning rod 23 close to the inner brush roller 2 is sleeved with a lower slider 24 slidably connected to the lower slide groove 22. The end of the lower positioning rod 23 away from the inner brush roller 2 is sleeved with a lower elastic member 25. The movable clamping rod 19 is rotatably connected to the lower slider 24, and a slot 26 is opened in the middle position of the bottom plate 21 away from the end of the fixed clamping rod 20.

[0030] The drinking water bucket cleaning device of the present invention, when putting the drinking water bucket into the inside of the bucket brushing machine body 1, only needs to turn the drinking water bucket upside down (with the bucket mouth facing downward), and then push the drinking water bucket between the circular plate 9 and the bottom plate 21. During the pushing process, the movable clamping rod 19 will move in the direction away from the inner brush roller 2 after being squeezed. After the drinking water bucket completely enters between the movable clamping rod 19 and the fixed clamping rod 20, the movable clamping rod 19 is no longer squeezed, and the upper slider 17 and the lower slider 24 at the upper end of the movable clamping rod 19 will be pushed toward the direction of the inner brush roller 2 by the upper elastic member 18 and the lower elastic member 25 respectively, so that the movable clamping rod 19 is tightly attached to the drinking water bucket, thereby restricting the drinking water bucket to prevent the drinking water bucket from detaching from the circular plate 9 and the bottom plate 21 by itself. At this time, the bucket mouth of the drinking water bucket will be in the clamping groove 26 and aligned with the inner brush roller 2. Then the equipment is started, and the cylinder 7 will drive the drinking water bucket to The top cover 8 is moved down together to insert the drinking water bucket onto the inner brush roller 2. The inner brush roller 2 and the outer brush roller 3 inside the bucket brush machine body 1 will rotate after the top cover 8 is closed, thereby cleaning the drinking water bucket. In the above operation steps, the user eliminates the step of aligning the barrel mouth (of the drinking water bucket) with the inner brush roller 2, making the bucket brush machine body 1 simpler and more convenient when loading. A plurality of bristles composed of nylon threads are fixedly connected to the surfaces of the inner brush roller 2 and the outer brush roller 3. When the inner brush roller 2 is inserted into the drinking water bucket and rotates, the nylon bristles on the surface of the inner brush roller 2 will be lifted up under the action of centrifugal force, and then contact with the inner wall of the drinking water bucket, thereby cleaning the drinking water bucket. Moreover, since the bristles composed of nylon threads have the ability to deform, when the drinking water bucket is inserted into the inner brush roller 2 or pulled out from the inner brush roller 2, the bristles composed of nylon threads will not hinder the drinking water bucket.

[0031] At the same time, when unloading, first turn off the inner brush roller 2 and the outer brush roller 3 through the control button, then start the cylinder 7, and let the cylinder 7 push the top cover 8 upward to make the drinking bucket separate from the inner brush roller 2. Then the user only needs to hold the mouth of the drinking bucket to pull the drinking bucket out from between the circular plate 9 and the bottom plate 21.

[0032] In addition, the start-up of the cylinder 7 and the rotation of the inner brush roller 2 and the outer brush roller 3 can be controlled by the control buttons and control system of the barrel brushing machine body 1, and the cylinder 7 is powered by an external air source (such as an air pump). The structure of the barrel brushing machine body 1, the inner brush roller 2 and the outer brush roller 3 in the present invention is similar to the prior art, and the patent authorization announcement number is CN215032074U, which discloses a barrel brushing machine for bottled drinking water production, so it will not be elaborated here.

[0033] As a preferred technical solution of the present invention, a frame 10 is fixedly connected to the top of the top cover 8, a limiting groove 12 is opened on one side of the frame 10, a threaded rod 13 is fixedly connected to one side of the top of the circular plate 9, the threaded rod 13 passes through the limiting groove 12 and is threadedly connected with the nut 14.

[0034] Specifically, after cleaning the drinking water barrel, if you want to simply clean the inner brush roller 2 and the outer brush roller 3, you can loosen the nut 14, then rotate the circular plate 9, rotate the threaded rod 13 to the other end of the limit groove 12, and then tighten the nut 14 again. At this time, the dynamic clamping rod 19 and the fixed clamping rod 20 will contact the inner brush roller 2 and the outer brush roller 3 respectively, and then start the barrel brushing machine body 1 to make the inner brush roller 2 and the outer brush roller 3 rotate at a low speed. The bristles on the inner brush roller 2 and the outer brush roller 3 will collide with the dynamic clamping rod 19 or the fixed clamping rod 20, allowing the impurities on the bristles of the inner brush roller 2 and the outer brush roller 3 to fall off, thereby achieving a self-cleaning effect.

[0035] As a preferred technical solution of the present invention, a plurality of collision rods 37 are fixedly connected to the outer wall of the bottom plate 21 , the top of the collision rod 37 is fixedly connected to the bottom of the circular plate 9 , and the number of the collision rods 37 is equal to the number of the outer brush rollers 3 .

[0036] Specifically, by adding the collision rod 37, the probability of the bristles of the inner brush roller 2 and the outer brush roller 3 colliding with each other is increased, thereby improving the cleaning efficiency.

[0037] As a preferred technical solution of the present invention, a high-pressure water pump 5 is fixedly connected to one side of the barrel brush machine body 1, and a water inlet pipe 6 connected thereto is fixedly connected to the water inlet position of the high-pressure water pump 5. A water spray channel 4 is provided through the center position of the inner brush roller 2, and the water outlet position of the high-pressure water pump 5 is connected to the lower end of the water spray channel 4.

[0038] Specifically, in the process of pulling the drinking water bucket out from the inner brush roller 2, the high-pressure water pump 5 will start to inject clean water into the water spray channel 4. The clean water will hit the bottom of the drinking water bucket, then flow down along the inner wall of the drinking water bucket, and finally flow out from the mouth of the drinking water bucket, thereby playing a flushing role and preventing impurities from adhering to the inner wall of the drinking water bucket. It is worth noting that the high-pressure water pump 5 here is also controlled by the control button and control system of the bucket brush machine body 1.

[0039] As a preferred technical solution of the present invention, a receiving groove 30 is provided in the middle position of the circular plate 9, and a water storage chamber 33 connected thereto is provided on the outer wall of the receiving groove 30. A plurality of guide grooves 35 are provided on the outer wall of the water storage chamber 33, and the number of the guide grooves 35 is equal to the number of the outer brush rollers 3. An outer water spray hole 36 matching the outer brush roller 3 is provided at one end of the guide groove 35 away from the water storage chamber 33, and an inner water spray hole 34 matching the inner brush roller 2 is provided at the bottom of the water storage chamber 33. A plurality of positioning blocks 31 are fixedly connected to the inner wall of the receiving groove 30, and a connecting sleeve 32 matching the positioning block 31 is slidably connected to the interior of the receiving groove 30, a hole groove connected to the water storage chamber 33 is provided on the upper end of the connecting sleeve 32, and the upper end of the connecting sleeve 32 is threadedly connected to the frame 10.

[0040] Specifically, when the circular plate 9 is rotated before self-cleaning, since the connecting sleeve 32 is threadedly connected to the frame 10, the connecting sleeve 32 will move downward synchronously during the rotation of the circular plate 9 until the connecting sleeve 32 is sleeved on the top of the inner brush roller 2. During the self-cleaning process, the clean water injected into the water spray channel 4 by the high-pressure water pump 5 will enter the water storage chamber 33 through the connecting sleeve 32, and be distributed by the guide groove 35, and finally sprayed onto the inner brush roller 2 and the outer brush roller 3 from the inner water spray hole 34 and the outer water spray hole 36, thereby playing a flushing role and facilitating the separation of impurities from the bristles of the inner brush roller 2 and the outer brush roller 3.

[0041] As a preferred technical solution of the present invention, a placement groove 28 matching the dynamic clamping rod 19 is provided at the bottom of the upper slide groove 15, a positioning plate 29 is fixedly connected to one end of the placement groove 28 close to the inner brush roller 2, and a positioning groove 27 matching the positioning plate 29 is provided at the upper end of the dynamic clamping rod 19.

[0042] Specifically, before self-cleaning, since there is no object squeezing between the two dynamic clamping rods 19, the upper elastic member 18 and the lower elastic member 25 will push the dynamic clamping rod 19 toward the inner brush roller 2, and the positioning plate 29 at the end of the placement groove 28 will be inserted into the positioning groove 27 at the upper end of the dynamic clamping rod 19, thereby preventing the dynamic clamping rod 19 from rotating, making it difficult for the bristles of the inner brush roller 2 and the outer brush roller 3 to achieve the desired collision effect.

[0043] As a preferred technical solution of the present invention, the four corners of the bottom of the top cover 8 are fixedly connected to the limiting rods 11, and the top of the barrel brushing machine body 1 is provided with limiting holes matching the limiting rods 11.

[0044] Specifically, the top cover 8 is restricted by the limiting rod 11, so that the top cover 8 is more stable when moving up and down.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
